Description

Technical Field

[0002] Currently, the stacking and transportation of packaged goods typically involves forming regularly shaped stacks, such as stacks of plastic bottles or glass bottles before canning. Usually, the stack is wrapped with one or more pieces of packaging film (protective film) to improve the stability of the packaged goods during transportation and prevent damage.

[0003] After the material stack is transported to the processing plant, the packaging film needs to be removed before unloading. Usually, the packaging film needs to be cut manually. Specifically, a knife is used to cut open the packaging film wrapped around the material stack, and then the packaged items are unloaded. This process is repeated.

[0056] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0057] Currently, the material stacks are wrapped with one or more layers of packaging film (protective film) to improve the stability of the packaged items during transportation and prevent damage. After the material stacks are transported to the processing plant, the packaging film needs to be removed before unloading. Typically, removing the packaging film requires manual cutting; specifically, a knife is used to cut open the packaging film wrapped around the material stack, and then the packaged items are unloaded, repeating this process.

[0058] However, when manually cutting packaging film, the manual operation is monotonous, and prolonged operation can easily lead to fatigue and high labor intensity. In addition, the knife may scratch the packaging, and it will also increase the production cost due to labor.

[0059] For this reason, see Figure 1 This application provides a novel automatic packaging film cutting device 10. Figure 1 This is a schematic diagram of an automatic packaging film cutting device 10 cutting a stack 90 according to an embodiment of this application. The automatic packaging film cutting device 10 is applied in a processing equipment (not shown) to automatically cut the packaging film on the outside of the stack 90, so that the processing equipment can process the packaged items (not shown) in the stack 90.

[0060] Understandably, the packages are stacked into a regular shape to form a stack 90. ​​Generally, the stack 90 has a hexahedral structure, such as a cuboid or cube. To facilitate the transportation of the stack 90, a plastic film is usually wrapped around the outside of the stack 90 as a packaging film (protective film). The packaging film is wrapped around the outer surface of the stack 90 to protect the packages inside.

[0061] Optionally, the packaging may include, but is not limited to, plastic bottles, glass bottles, and other structures that are transported by stacking. Of course, in other embodiments of this application, the packaging may also be a box, etc.

[0062] Taking glass bottles as an example, empty glass bottles are transported to processing equipment for high-temperature sterilization, filling, and other processing. Before being transported to the processing equipment, the glass bottles are usually stacked into a stack 90, and a packaging film is wrapped around the outside of the stack 90. ​​This facilitates both storage and transportation of the glass bottles.

[0063] After the stack 90 is conveyed to the processing equipment, the packaging film on the outside of the stack 90 is cut by the automatic packaging film cutting device 10 of this application. Then, the packaging film can be removed. Alternatively, the glass bottles can be directly picked up by the unloading device (not shown) and transferred to the processing device for processing. The processing device processes the glass bottles. The principle of processing the stack 90 is essentially the same for other packaging structures, and will not be described in detail here.

[0064] It is worth noting that the focus of this application is on the cutting of the packaging film by the automatic packaging film cutting device 10. The stacking of the material stack 90, the wrapping of the packaging film, the unloading of the unloading device, and the processing of the processing device can be handled by currently feasible structures, and will not be described in detail here.

[0065] The automatic packaging film cutting device 10 of this application can automatically cut each surface of the outer packaging film of the stack 90 without the need for manual cutting by operators, thereby reducing the labor intensity of operators and reducing production costs. At the same time, the cutting mechanism can control the cutting thickness to avoid scratching the packaging inside the packaging film, ensuring the performance and appearance integrity of the packaging.

[0066] To better illustrate the specific structure of the automatic packaging film cutting device 10, the structure of the stack 90 is briefly described here. It should be noted that the automatic packaging film cutting device 10 cuts the six surfaces of the packaging film on the outside of the stack 90. ​​The stack 90 is hexahedral, and after the packaging film is wrapped around its outside, it has six surfaces. For example... Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 The diagram shows a stack of materials 90 wrapped in packaging film.

[0067] The packaging film has a first surface 901 and a second surface 902 disposed opposite to each other along a first direction, and a third surface 904 disposed opposite to each other along a second direction. The first surface 901, the second surface 902, the third surface 903, and the fourth surface 904 surround the side of the packaging film. The packaging film has a top surface 905 and a bottom surface (not shown) disposed opposite to each other along a third direction. The top surface 905 is located above the packaging film, and the bottom surface is located below the packaging film.

[0068] It is worth noting that the first direction, the second direction, and the third direction, such as... Figure 1 and Figure 2 As shown. The first direction is the left-right direction (the length direction of the stack 90), which is also the direction in which the stack 90 is pushed, and the stack 90 moves from right to left. The second direction is the front-back direction (the thickness direction of the stack 90), and the third direction is the up-down direction (the top and bottom direction, the height direction of the stack 90).

[0069] The following description of the specific structure of the automatic packaging film cutting device 10 will all use the following terms. Figure 1 and Figure 2 The directions shown are the baseline, and the first, second, and third directions will not be discussed in detail later.

[0070] The automatic packaging film cutting device 10 can cut the first surface 901, the second surface 902, the third surface 903, the fourth surface 904, and the top surface 905. After cutting, the packaging film is in a broken state. At this time, the cut packaging film can be removed from the stack 90. ​​Of course, the packaging film can also be left unremoved, and the package can be directly grabbed from the cut to achieve unloading.

[0071] The following describes the specific structure of an automatic packaging film cutting device 10 according to an embodiment.

[0072] See Figures 1 to 4 In one embodiment, the automatic packaging film cutting device 10 includes a frame 100, a conveying mechanism 200, and a plurality of cutting mechanisms. The conveying mechanism 200 passes through the frame 100 along a first direction and has a cutting position (not shown). The conveying mechanism 200 pushes the stack 90 to the cutting position along the first direction. The plurality of cutting mechanisms are respectively disposed in the frame 100 and / or the conveying mechanism 200 and correspond to the cutting position. The plurality of cutting mechanisms correspond to the surface of the stack 90 exposed at the cutting position, and each cutting mechanism is used to cut the corresponding surface of the outer packaging film of the stack 90. Figure 3 for Figure 1 The front view of the automatic packaging film cutting device 10 shown is shown. Figure 4 for Figure 1 Side view of the automatic packaging film cutting device 10 shown.

[0073] The frame 100 is a component supporting the cutting mechanism of the automatic packaging film cutting device 10, and the conveying mechanism 200 is a mechanism for pushing the stack 90. ​​The conveying mechanism 200 extends along a first direction, can extend through the frame 100, the frame 100 can surround the periphery of the conveying mechanism 200, and the conveying mechanism 200 protrudes from both sides of the frame 100 in the first direction.

[0074] Multiple cutting mechanisms are respectively disposed on the frame 100 and / or the conveying mechanism 200. The multiple cutting mechanisms can cut the surfaces corresponding to the outer packaging film of the material stack 90 along the first direction, the second direction and the third direction, respectively.

[0075] The position of the conveying mechanism 200 corresponding to the frame 100 is the cutting position. After the stack 90 is placed on the conveying mechanism 200, the conveying mechanism 200 pushes the stack 90 along the first direction. When the stack 90 is pushed to the cutting position, the conveying mechanism 200 stops, at which point the stack 90 is in the cutting position. In this way, each cutting mechanism can cut the surface corresponding to the outer packaging film of the stack 90. ​​By using multiple cutting mechanisms to cut various surfaces of the packaging film, it is convenient for subsequent destacking and unloading operations.

[0076] Furthermore, after the cutting is completed, the conveying mechanism 200 can push the cut stack 90 to the unloading position, and at the same time, push the next stack 90 to be cut to the cutting position. This process is repeated to achieve continuous cutting of the outer packaging film of the stack 90 and improve production efficiency.

[0077] The automatic packaging film cutting device 10 of the above embodiment uses multiple cutting mechanisms to automatically cut each surface of the outer packaging film of the stack 90, eliminating the need for manual cutting by operators, reducing the labor intensity of operators, and reducing production costs. At the same time, the cutting mechanism can control the cutting thickness to avoid scratching the packaging inside the packaging film, ensuring the performance and appearance integrity of the packaging, improving cutting efficiency, and facilitating the subsequent processing of the stack 90 by the subsequent processing equipment.

[0078] See Figure 1 , Figure 2 and Figure 4 In one embodiment, the frame 100 includes two side support frames 110, a top support frame 120, and a bottom support frame 130. The bottom support frame 130 extends along a second direction, the two side support frames 110 extend along a third direction and are spaced apart along the second direction from the bottom support frame 130, and the top support frame 120 is disposed above the two side support frames 110 and above the bottom support frame 130 along the second direction.

[0079] Furthermore, the bottom support frame 130 is located below the conveying mechanism 200, the top support frame 120 is located above the conveying mechanism 200, and the two side support frames 110 are located on the front and rear sides of the conveying mechanism 200. Thus, the two side support frames 110, the top support frame 120, and the bottom support frame 130 can form a quadrilateral structure, surrounding the periphery of the conveying mechanism 200. At least part of the cutting mechanism can be supported by the side support frames 110 and the top support frame 120.

[0080] Optionally, the side support frame 110, top support frame 120, and bottom support frame 130 can be frame structures to ensure the stability of the frame 100 structure and the reliability of the support for the cutting mechanism. Of course, in other embodiments of this application, the side support frame 110, top support frame 120, and bottom support frame 130 can also be columns, beams, or other structural forms.

[0081] Optionally, the bottom support frame 130 is mounted on the mounting surface. This mounting surface includes, but is not limited to, the ground or a support platform, and can also be other platform surfaces that support and mount processing equipment.

[0082] See Figure 1 and Figure 3 In one embodiment, the conveying mechanism 200 includes a conveying bracket (not shown), a conveying drive (not shown), and a conveying transmission (not shown). The conveying drive is disposed on the conveying bracket, and the conveying transmission is movably disposed on the conveying bracket and can output movement along a first direction.

[0083] The conveying drive component is connected to the conveying transmission component. When the conveying drive component is working, it can drive the conveying transmission component to move, and then the conveying transmission component can drive the material stack 90 to move along the first direction so that the material stack 90 to be cut can be conveyed to the cutting position, and the cut material stack 90 can be conveyed to the unloading position.

[0084] Optionally, the conveying drive is a motor. Optionally, the conveying transmission is a belt drive structure, i.e., belt conveyor. Two pulleys are rotatably mounted on the conveying support at a distance from each other along a first direction, and a synchronous belt is sleeved on the two pulleys. When the conveying drive drives the pulleys to rotate, the pulleys can drive synchronous movement along the first direction, realizing the conveying of the stack 90.

[0085] Optionally, the conveying drive may also include multiple rollers arranged side by side along the first direction. The rollers are driven synchronously by a belt drive or a chain drive. In this way, the conveying drive can drive the multiple rollers to rotate through the belt drive or chain drive, thereby realizing the conveying of the stack 90 along the first direction.

[0086] In this embodiment, the conveying mechanism 200 is a belt conveyor. Of course, in other embodiments of this application, the conveying mechanism 200 may also be other mechanisms capable of pushing the stack 90 along the first direction.

[0087] See Figure 1 , Figure 2 and Figure 4In one embodiment, the plurality of cutting mechanisms includes at least a first cutting mechanism 300, a second cutting mechanism 400, a third cutting mechanism 500, and a fourth cutting mechanism 600. The first cutting mechanism 300 is located on the side of the conveying mechanism 200 and is used to cut the first surface 901 and the second surface 902 of the stack 90 opposite to each other in the first direction along a second direction. The second cutting mechanism 400 is located on the side of the conveying mechanism 200 and is used to cut the third surface 903 and the fourth surface 904 of the stack 90 opposite to each other in the second direction along the first direction. The third cutting mechanism 500 is located above the conveying mechanism 200 and is used to cut the top surface 905 of the stack 90 along the first direction. The fourth cutting mechanism 600 is located in a third direction corresponding to the first surface 901 of the stack 90 and is used to cut the first surface 901 of the stack 90 along the third direction.

[0088] The first cutting mechanism 300 is rotatably mounted on the side support frame 110 of the frame 100 and located behind the conveying mechanism 200. When the first cutting mechanism 300 rotates, it can move closer to or further away from the first surface 901 and the second surface 902. When the first cutting mechanism 300 is not cutting the packaging film, it moves away from the cutting position. In this way, the first cutting mechanism 300 will not obstruct the conveying mechanism 200 from pushing the stack 90, ensuring that the stack 90 can move accurately along the first direction.

[0089] After the stack 90 is pushed to the cutting position, the first cutting mechanism 300 rotates relative to the frame 100, allowing it to move to the left and right sides of the stack 90. ​​At this point, the first cutting mechanism 300 can align with the first surface 901 and the second surface 902, thus cutting the first surface 901 and the second surface 902. After cutting, the first cutting mechanism 300 rotates again relative to the frame 100 to return to its initial position away from the stack 90, facilitating the pushing away of the cut stack 90 and the transport of the stack 90 to be cut to the cutting position.

[0090] The second cutting mechanism 400 is disposed on the two side support frames 110 of the frame 100 and can move along the second direction. The second cutting mechanism 400 is aligned with the third surface 903 and the fourth surface 904 of the material stack 90. ​​After the material stack 90 moves to the cutting position, the second cutting mechanism 400 can move along the second direction to cut the third surface 903 and the fourth surface 904. After cutting is completed, the second cutting mechanism 400 can return to the initial position along the second direction.

[0091] The third cutting mechanism 500 is mounted on the top support frame 120 of the frame 100. The third cutting mechanism 500 can move up and down in the third direction to align with the top surface 905 of the material stack 90. ​​After the material stack 90 moves to the cutting position, the third cutting mechanism 500 moves in the third direction to cut the top surface 905. After cutting is completed, the third cutting mechanism 500 returns to the initial position in the third direction.

[0092] The fourth cutting mechanism 600 is located on the front side of the frame 100 and is mounted on the mounting surface. The fourth cutting mechanism 600 is rotatably configured to move closer to or further away from the first surface 901. After the stack 90 moves to the cutting position, the fourth cutting mechanism 600 rotates to align with the first surface 901 to cut the first surface 901 along a third direction. After cutting is completed, the fourth cutting mechanism 600 rotates back to its initial position.

[0093] Optionally, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600 can perform cutting in a certain order. Of course, in other embodiments of this application, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600 can perform at least partial cutting without interference.

[0094] like Figure 1 and Figure 2 As shown, after the first cutting mechanism 300 cuts the first surface 901 and the second surface 902, a first slit 911 along the second direction is formed on the first surface 901, and a second slit 921 along the second direction is formed on the second surface 902. After the second cutting mechanism 400 cuts the third surface 903 and the fourth surface 904, a third slit 931 along the first direction is formed on the third surface 903, and a fourth slit 941 along the first direction is formed on the fourth surface 904.

[0095] After the third cutting mechanism 500 cuts the top surface 905, it forms a fifth slit 951 along the first direction on the top surface 905. After the fourth cutting mechanism 600 cuts the first surface 901, it forms a sixth slit 912 along the third direction on the first surface 901, and the sixth slit 912 intersects with the first slit 911.

[0096] See Figure 1 and Figure 2 In one embodiment, the first slit 911 and the second slit 921 cut by the first cutting mechanism 300 to the first surface 901 and the second surface 902, and the third slit 931 and the fourth slit 941 cut by the second cutting mechanism 400 to the third surface 903 and the fourth surface 904, are on the same surface.

[0097] In this embodiment, the first slit 911, the second slit 921, the third slit 931, and the fourth slit 941 are coplanar and interconnected, which facilitates the removal of the packaging film and, consequently, the unpacking and unloading operations of the stack 90.

[0098] Of course, in other embodiments of this application, the first slit 911 and the second slit 921 are offset from the third slit 931 and the fourth slit 941 along a third direction. In this way, the removal of the packaging film can also be achieved.

[0099] See Figure 1 In one embodiment, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600 cut the packaging film using a thermomelting cutting method. That is, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600 utilize the principle of electric heating for thermomelting cutting.

[0100] This avoids the dulling problem that occurs when using ordinary blades for cutting, thus preventing incomplete cuts and ensuring that the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600 can accurately cut, thereby improving the cutting stability of the automatic packaging film cutting device 10.

[0101] The specific structures of the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 will be explained later. Here, we will first introduce the structure of the positioning mechanism 800 that positions the stack 90.

[0102] See Figure 1 In one embodiment, the automatic packaging film cutting device 10 further includes a positioning mechanism 800, which is disposed on the conveying mechanism 200 and is used to position the stack 90 at the cutting position. The positioning mechanism 800 is movably disposed at the cutting position and can limit the stack 90.

[0103] When the conveying mechanism 200 pushes the stack 90, the positioning mechanism 800 can block and abut against the stack 90, thus limiting the stack 90. ​​In this way, the stack 90 can be accurately positioned at the cutting position, making it easy for the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 to align with the stack 90.

[0104] See Figure 1 and Figure 5 In one embodiment, the positioning mechanism 800 includes a first positioning component 810, which is disposed on the conveying mechanism 200 and can be raised and lowered in a third direction to limit the material stack 90 at the cutting position. Figure 5 for Figure 1 A schematic diagram of the first positioning component 810 in the automatic packaging film cutting device 10 shown.

[0105] The first positioning component 810 is located on the left side of the cutting position. The first positioning component 810 can abut against the first surface 901 of the stack 90 to limit the position of the stack 90. ​​Before the conveying mechanism 200 pushes the stack 90, it controls the first positioning component 810 to rise (move upwards along a third direction). Then, the conveying mechanism 200 pushes the stack 90 to move along the first direction. When the stack 90 contacts the first positioning component 810, the conveying mechanism 200 stops working. At this time, the stack 90 is in the cutting position.

[0106] In this way, the moving material stack 90 is limited by the first positioning component 810 so that the material stack 90 can be accurately transported to the cutting mechanism, so that the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 can be aligned with the surface of the material stack 90, ensuring the accuracy of the packaging film cutting and facilitating the subsequent removal of the packaging film and unloading operations.

[0107] After the material stack 90 is cut, the first positioning component 810 descends relative to the conveying mechanism 200 (moving downwards along a third direction). At this point, the material stack 90 is no longer obstructed, and the conveying mechanism 200 can push the material stack 90 past the first positioning component 810 to the unloading position. Furthermore, after the material stack 90 has passed the first positioning component 810, the first positioning component 810 can rise again to limit the next material stack 90 to be cut.

[0108] See Figure 1 and Figure 5 In one embodiment, the first positioning component 810 includes a first positioning drive 811 and a first positioning component 812. The first positioning drive 811 is disposed on the conveying mechanism 200 and outputs a lifting motion along a third direction. The first positioning component 812 is disposed at the output end of the first positioning drive 811 and is used to fit the first surface 901.

[0109] The first positioning drive 811 is the power source for the first positioning assembly 810, and the first positioning drive 811 can output lifting motion along a third direction. The first positioning drive 811 is disposed in the conveying mechanism 200, and the output end of the first positioning drive 811 is equipped with a first positioning member 812, which can conform to the first surface 901.

[0110] The first positioning drive 811 can drive the first positioning member 812 to rise or fall. When the first positioning drive 811 drives the first positioning member 812 to rise, the first positioning member 812 can conform to the first surface 901 to limit the material stack 90. ​​When the first positioning drive 811 drives the first positioning member 812 to fall, the first positioning member 812 can disengage from the first surface 901, releasing the limitation on the material stack 90.

[0111] Optionally, the first positioning drive member 811 is a lifting motor. Of course, in other embodiments of this application, the first positioning drive member 811 may also be a cylinder. Optionally, the first positioning member 812 is a positioning plate; further, the first positioning member 812 is L-shaped, so that the first positioning member 812 can fit against the first surface 901 and the bottom surface. Of course, in other embodiments of this application, the first positioning member 812 may also be a frame structure or a limiting post, etc.

[0112] See Figure 1 and Figure 5 In one embodiment, the positioning mechanism 800 further includes a fixing component 813 and a first guide portion 814. The fixing component 813 is disposed on the first positioning drive component 811, and the first guide portion 814 guides and connects the fixing component 813 and the first positioning component 812. The output end of the first positioning drive component 811 passes through the fixing component 813 and connects to the first positioning component 812.

[0113] When the first positioning drive 811 drives the first positioning member 812 to move, the first positioning member 812 can drive the first guide part 814 to move along a third direction. The first guide part 814 guides the lifting and lowering of the first positioning member 812, ensuring that the first positioning member 812 accurately fits or detaches from the first surface 901.

[0114] Optionally, the fixing component 813 is a fixing plate. Of course, in other embodiments of this application, the fixing component 813 may also be a fixing seat or a fixing frame, etc. Optionally, the first guide portion 814 is a linear bearing. Of course, in other embodiments of this application, the first guide portion 814 may also be a guide rod, and the first positioning component 812 has a guide hole that mates with the guide rod.

[0115] In one embodiment, there are multiple first positioning components 810, which are either integral or separately arranged along the second direction. Each first positioning element 812 corresponds to one first positioning drive element 811. Optionally, each first positioning element 812 corresponds to one or at least two first guide portions 814.

[0116] See Figure 1 and Figure 6In one embodiment, the positioning mechanism 800 further includes two sets of second positioning components 820, which are spaced apart on the conveying mechanism 200 or the frame 100 along the second direction and are movable along the second direction. Figure 6 for Figure 1 The diagram shows the integration of the second positioning component 820 and the second cutting mechanism 400 in the automatic packaging film cutting device 10.

[0117] There are two sets of second positioning components 820, symmetrically arranged along the second direction on the side support frame 110 of the frame 100. The two second positioning components 820 correspond to the third surface 903 and the fourth surface 904 of the stack 90, respectively. Furthermore, the second positioning components 820 are movable along the second direction. Thus, the second positioning components 820 can move in the second direction to approach or move away from the third surface 903 and the fourth surface 904.

[0118] When the conveying mechanism 200 pushes the stack 90, after the first surface 901 of the stack 90 abuts against the stack 90, the conveying mechanism 200 stops, and the stack 90 is in the cutting position. Then, the two second positioning components 820 move along the second direction and respectively abut against the third surface 903 and the fourth surface 904. At this time, the two second positioning components 820 can clamp the stack 90 in the second direction, thus fixing the stack 90 in the cutting position.

[0119] See Figure 1 and Figure 6 In one embodiment, the second positioning component 820 includes a second positioning drive 821 and a second positioning component 822. The second positioning drive 821 is disposed on the conveying mechanism 200 or the frame 100, and the second positioning component 822 is disposed at the output end of the second positioning component 822, so that the second positioning component 822 moves along the second direction to approach or move away from the third surface 903 or the fourth surface 904.

[0120] The second positioning drive 821 is the power source for the movement of the second positioning assembly 820, and the second positioning drive 821 can output movement along the second direction. The second positioning drive 821 is disposed on the frame 100 or the conveyor frame 100, and the output end of the second positioning drive 821 is equipped with a second positioning member 822, which can conform to the third surface 903 or the fourth surface 904 (the following description only uses the conformation of the second positioning member 822 to the third surface 903 as an example).

[0121] The second positioning drive member 821 can drive the second positioning member 822 to move along the second direction to approach or move away from the third surface 903. When the second positioning drive member 821 is in its initial position, there is a certain distance between the second positioning member 822 and the third surface 903. Then, the second positioning drive member 821 drives the second positioning member 822 to move towards the third surface 903, so as to approach and then abut against the third surface 903. The second positioning drive member 821 also drives the second positioning member 822 to move away from the third surface 903, so as to disengage and move away from the third surface 903.

[0122] Optionally, the second positioning drive member 821 is a moving motor. Of course, in other embodiments of this application, the second positioning drive member 821 may also be a cylinder. Optionally, the second positioning member 822 is a positioning plate; further, the second positioning member 822 is L-shaped, so that the second positioning member 822 can fit against the third surface 903 and the fourth surface 904. Of course, in other embodiments of this application, the second positioning member 822 may also be a frame structure or a limiting post, etc.

[0123] See Figure 1 and Figure 6 In one embodiment, the positioning mechanism 800 further includes a second guide portion (not shown) and a third guide portion (not shown). The second guide portion is disposed on the frame 100 or the conveying mechanism 200 along a second direction, and the third guide portion is movably disposed on the second guide portion. The second positioning member 822 is disposed on the third guide portion.

[0124] When the second positioning drive 821 outputs movement along the second direction, the second positioning drive 821 drives the second positioning member 822 to move, and then the second positioning member 822 drives the second guide portion to move along the third guide portion. The movement of the second positioning member 822 is guided by the second guide portion and the third guide portion to ensure that the second positioning member 822 accurately fits into or disengages from the third surface 903.

[0125] Optionally, the second guide portion is a guide rail, and the third guide portion is a guide slider, with the guide slider slidably disposed on the guide rail; or, the second guide portion is a guide slider, and the third guide portion is a guide rail. Of course, in other embodiments of this application, the second and third guide portions may also be linear axes or guide rods, or other structures capable of guidance.

[0126] See Figure 1 and Figure 6 In one embodiment, the second positioning component 820 is integrated with the second cutting mechanism 400. That is, the second cutting mechanism 400 is disposed on the second positioning component 820, and further, the second cutting mechanism 400 is disposed on the second positioning member 822 of the second positioning component 820.

[0127] When the second positioning drive 821 drives the second positioning member 822 to position the stack 90, the second positioning member 822 can drive the second cutting mechanism 400 to move synchronously toward the third surface 903 and the fourth surface 904, so that the second cutting mechanism 400 can cut the third surface 903 and the fourth surface 904.

[0128] Furthermore, by integrating the second positioning component 820 with the second cutting mechanism 400, only a first positioning drive component 811 and a second positioning guide are needed to guide the second positioning component 820 and the second cutting mechanism 400 along the second direction, thereby reducing the complexity of the structure and lowering the cost.

[0129] Of course, in other embodiments of this application, the second positioning component 820 and the second cutting component 420 can also be set independently. That is, the second positioning component 820 and the second cutting component 420 are respectively set in the conveying mechanism 200 and / or the frame 100, and move along the second direction respectively, as long as the second positioning component 820 and the second cutting component 420 do not interfere with each other.

[0130] This application employs a positioning mechanism 800 to position the stack 90 at the cutting position: when the conveying mechanism 200 pushes the stack 90, it can abut against the first positioning component 810, and the conveying mechanism 200 stops working, so that the stack 90 is in the cutting position; then, the two first positioning components 810 are driven to move closer to each other to clamp the stack 90, and the stack 90 is positioned in the second direction. In this way, the stack 90 can be reliably fixed to the cutting position, ensuring that the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 can accurately cut the stack 90.

[0131] In one embodiment, the automatic packaging film cutting device 10 includes a control host. The first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 are electrically connected to the control host. The control host realizes automatic cutting control of the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600, eliminating the need for manual operation and reducing labor intensity.

[0132] Of course, in other embodiments of this application, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500 and the fourth cutting mechanism 600 can also be centrally controlled by the control host of the packaging equipment.

[0133] It is worth noting that when describing the specific structures of the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, and the fourth cutting mechanism 600, only one of the same structures will be used as an example for explanation, and will not be repeated in the following text.

[0134] See Figure 1 , Figure 7 and Figure 8 In one embodiment, the first cutting mechanism 300 includes a first mounting member 310, a first driver 320, and two sets of first cutting components 330. The first driver 320 is disposed on the frame 100. The first mounting member 310 is rotatably connected to the frame 100 and disposed at the output end of the first driver 320. The two sets of first cutting components 330 extend along a second direction and are symmetrically disposed on the first mounting member 310 along a first direction.

[0135] The first driver 320 can drive the first mounting component 310 to rotate the two sets of first cutting mechanisms 300, so that the two sets of first cutting components 330 can correspond to or move away from the first surface 901 and the second surface 902. Figure 7 for Figure 1 A schematic diagram of the first cutting mechanism 300 in the automatic packaging film cutting device 10 shown. Figure 8 for Figure 7 A partial schematic diagram of the first cutting mechanism 300 at point A.

[0136] In this embodiment, the two sets of first cutting components 330 correspond to the first surface 901 and the second surface 902 of the material stack 90, respectively. Furthermore, the two sets of first cutting components 330 are connected as a single unit via a first mounting member 310, enabling synchronous movement control of the two sets of first cutting components 330. Of course, in other embodiments of this application, the two sets of first cutting components 330 can also be rotatably mounted directly on the frame 100, allowing the two first cutting components 330 to move independently and correspond to the first surface 901 and the second surface 902, respectively.

[0137] The first cutting component 330 is the main component for cutting the packaging film. Two sets of first cutting components 330 are symmetrically arranged in the first mounting part 310 along the first direction. The first cutting component 330 on the left corresponds to the first surface 901, and the first cutting component 330 on the right corresponds to the second surface 902. The first surface 901 and the second surface 902 are cut by the two sets of first cutting components 330.

[0138] The first driver 320 is fixedly mounted on the side support frame 110 at the rear of the frame 100. The output end of the first driver 320 is connected to the first mounting member 310, and both ends of the first mounting member 310 are rotatably connected to the side support frame 110. When the first driver 320 drives the first mounting member 310 to move, the first mounting member 310 can rotate relative to the frame 100, thereby driving the two first cutting components 330 to rotate.

[0139] When the first cutting mechanism 300 is not cutting, it is located behind the conveying mechanism 200 and does not extend above the conveying mechanism 200, thus not obstructing the stack 90. ​​The stack 90 is pushed to the cutting position, and then the first driver 320 drives the first mounting member 310 to rotate relative to the frame 100, so that the two first cutting components 330 correspond to the first surface 901 and the second surface 902 respectively.

[0140] In this way, the two first cutting components 330 can simultaneously cut the first surface 901 and the second surface 902. After cutting, the first driver 320 drives the first mounting component 310 to move the first heated cutting component 333 away from the first surface 901 and the second surface 902. At this time, the first cutting mechanism 300 will not obstruct the stack 90, which facilitates the subsequent pushing of the stack 90.

[0141] Optionally, the first driver 320 is a motor or a cylinder. Optionally, the first driver 320 is connected to the first mounting member 310 via a connecting rod. Optionally, the first mounting member 310 is a connecting rod. Of course, in other embodiments of this application, the first mounting member 310 may also be a connecting bracket, etc. Optionally, the first mounting member 310 is rotatably mounted to the side support frame 110 via bearings.

[0142] See Figure 7 and Figure 8 In one embodiment, the first cutting assembly 330 includes a first support member 331, a first cutting drive member 332, and a first heating cutter 333. The first cutting drive member 332 is disposed on the first mounting member 310. The first support member 331 is movably disposed on the first mounting member 310 along a first direction and connected to the output end of the first cutting drive member 332. The first heating cutter 333 is disposed on the first support member 331 along a second direction. The first cutting drive member 332 can drive the first support member 331 to move along the first direction, so that the first heating cutter 333 heats and cuts the first surface 901 or the second surface 902.

[0143] The first support member 331 is a component that supports the first cutting assembly 330. The first support member 331 is disposed on the first mounting member 310 along the second direction, and the first support member 331 is movable on the first mounting member 310 and can move along the first direction. The first heated cutting member 333 is disposed on the surface of the first support member 331 facing the stack 90. ​​When the first driver 320 drives the first cutting assembly 330 to align with the first surface 901 (the second surface 902 will not be described), the first heated cutting member 333 can cut the first surface 901.

[0144] The first heating and cutting element 333 is electrically connected to the control host, which can control the first heating and cutting element 333 to be energized or de-energized. When the first heating and cutting element 333 is energized, it can perform thermal melting cutting on the first surface 901. Optionally, the first heating and cutting element 333 is a heating wire. Of course, in other embodiments of this application, the first heating and cutting element 333 may also be blade-shaped or other shapes.

[0145] Understandably, in the initial position, the distance between the two sets of first cutting components 330 is greater than the length of the stack 90 along the first direction. Thus, when the first driver 320 drives the first mounting member 310 to rotate the first cutting components 330, the two sets of first cutting components 330 can move into the left and right sides of the stack 90 to accurately align the first surface 901 and the second surface 902.

[0146] At this time, there is a certain distance between the first cutting component 330 and the first surface 901 and the second surface 902, and the first heating cutting component 333 cannot cut the first surface 901 and the second surface 902. Therefore, this application provides a first cutting drive component 332 on the first mounting component 310. The output end of the first cutting drive component 332 is connected to the first support component 331 and can output movement in a first direction. Optionally, the first cutting drive component 332 is a motor or a cylinder.

[0147] In this way, the first cutting drive 332 can drive the first support 331 to move the first heated cutting component 333 toward the first surface 901 and the second surface 902 to cut the first surface 901 and the second surface 902. After cutting, the first cutting drive 332 drives the first support 331 to move the first heated cutting component 333 away from the first surface 901 and the second surface 902. Then, the first driver 320 drives the first mounting component 310 to move the two sets of first cutting components 330 back to their initial positions.

[0148] See Figure 7 and Figure 8 In one embodiment, the first cutting assembly 330 further includes a first slide rail 334 and a first slider 335. The first slide rail 334 is disposed on the first mounting member 310 along a first direction, and the first slider 335 is slidably disposed on the first slide rail 334 and connected to the first support member 331. Thus, when the first cutting drive member 332 drives the first support member 331 to move along the first direction, the first support member 331 can drive the first slider 335 to move along the first slide rail 334, so that the first cutting assembly 330 can accurately approach or move away from the first surface 901 along the first direction.

[0149] See Figure 7 and Figure 8In one embodiment, the first cutting assembly 330 further includes a first tensioning member 336, one end of which is connected to the first support member 331, and the other end of which is connected to the first heated cutting member 333. The first tensioning member 336 can tension the first heated cutting member 333 to keep it straight, thereby ensuring the cutting effect on the first surface 901 and the second surface 902.

[0150] Optionally, the first tensioning member 336 is a combination of a spring and a pull rod. Of course, in other embodiments of this application, the first tensioning member 336 may also be a tensioning wheel or other structure capable of tensioning the first heated cutting member 333.

[0151] See Figure 7 and Figure 8 In one embodiment, the first cutting mechanism 300 further includes two sets of first adsorption components 340, each set of first adsorption components 340 being disposed along the second direction on the corresponding first cutting component 330, and the first adsorption components 340 being used to adsorb the first surface 901 or the second surface 902.

[0152] Each first adsorption component 340 is disposed on a first support member 331 and extends toward the stack 90. ​​The first adsorption component 340 can adsorb the first surface 901 or the second surface 902. Before the first heated cutting member 333 cuts the first surface 901, the first adsorption component 340 adsorbs the first surface 901. This facilitates the first heated cutting member 333 in cutting the first surface 901 and also avoids damage to the packaging in the stack 90 by the first heated cutting member 333.

[0153] See Figure 7 and Figure 8 In one embodiment, the first adsorption assembly 340 includes a first adsorption box 341 and a plurality of first adsorption elements 342. The first adsorption box 341 is disposed on the first support member 331, and the plurality of first adsorption elements 342 are disposed on the surface of the first adsorption box 341 facing the material stack 90 and are connected to the first adsorption box 341. The first adsorption box 341 can be connected to an external negative pressure source to control the first adsorption elements 342 to perform adsorption operations.

[0154] The first driver 320 drives the first mounting component 310 to move the first cutting component 330 to align with the first surface 901. Then, the negative pressure source evacuates each of the first adsorption components 342 through the first adsorption box 341 so that the first adsorption components 342 can adsorb onto the first surface 901, which facilitates the subsequent cutting of the first surface 901 by the first heated cutting component 333.

[0155] Optionally, the first adsorption element 342 is a vacuum suction cup. The host control controls the first adsorption element 342 to perform adsorption or release actions. Of course, in other embodiments of this application, the first adsorption element 342 may also be a pneumatic adsorption element or an electric adsorption element, etc., which will not be described in detail here.

[0156] See Figure 7 and Figure 8 In one embodiment, the first adsorption assembly 340 further includes a first adsorption drive 343, which is disposed on the first support 331 and has its output end connected to the first adsorption box 341. The first adsorption drive 343 can drive the first adsorption box 341 to move multiple first adsorption elements 342 along a first direction, so that the first adsorption elements 342 can approach or move away from the first surface 901 or the second surface 902 to adsorb or release the first surface 901 or the second surface 902. Optionally, the first adsorption drive 343 is a motor or a cylinder.

[0157] See Figure 1 and Figure 6 In one embodiment, there are two sets of second cutting mechanisms 400, symmetrically arranged along a second direction. The two sets of second cutting mechanisms 400 correspond to the third surface 903 and the fourth surface 904, respectively. The two sets of second cutting mechanisms 400 are spaced apart along the second direction, and the two sets of second cutting components 420 are symmetrical and extend along a first direction. Thus, the two second cutting mechanisms 400 are respectively located on the front and rear sides of the conveying mechanism 200, and can respectively abut against the third surface 903 and the fourth surface 904 to cut the third surface 903 and the fourth surface 904.

[0158] In this embodiment, the movements of the two sets of second cutting mechanisms 400 are independent of each other. That is, the two sets of second cutting mechanisms 400 are respectively connected to the control host, and the control host controls the two sets of second cutting mechanisms 400 to move towards or away from the material stack 90. ​​Of course, in other embodiments of this application, the two sets of second cutting mechanisms 400 can also be synchronously connected by components such as connecting rods, as long as interference with other cutting mechanisms is avoided and the conveying of the material stack 90 is not affected.

[0159] In this embodiment, the second cutting mechanism 400 is disposed on the second positioning member 822 of the second positioning component 820. Thus, when the second positioning component 820 moves along the second direction, it can drive the second cutting mechanism 400 to move synchronously along the second direction, allowing the second cutting mechanism 400 to abut against or disengage from the third surface 903. Of course, in other embodiments of this application, the second cutting mechanism 400 can also be directly disposed on the frame 100, and driven to move along the second direction by an independent moving component such as a linear motor.

[0160] See Figure 1 and Figure 6 In one embodiment, the second cutting mechanism 400 includes a second mounting member 410 and a second cutting assembly 420. The second mounting member 410 is disposed on the frame 100 and / or the conveying mechanism 200, and the second cutting assembly 420 is disposed on the second mounting member 410 along a first direction and corresponds to a third surface 903 or a fourth surface 904.

[0161] The second mounting member 410 is a component that supports the second cutting mechanism 400. The second mounting member 410 is disposed on the second positioning member 822, or it may be disposed on the frame 100. Of course, the second mounting member 410 may also be part of the frame 100 or the second positioning member 822. In this embodiment, the second mounting member 410 is a combination structure of a mounting plate or mounting rod, such as... Figure 1 and Figure 6 The second cutting component 420 is fixed to the second positioning component 822 by the second mounting component 410.

[0162] The second cutting assembly 420 is the main component for cutting the packaging film. The second cutting assemblies 420 of the two sets of second cutting mechanisms 400 are arranged along the second direction on the side support frame 110 of the frame 100, and respectively correspond to the third surface 903 and the fourth surface 904. Cutting of the third surface 903 and the fourth surface 904 is achieved through the two sets of second cutting assemblies 420. Here, only the second cutting assembly 420 located in front of the conveying mechanism 200 is described; this second cutting assembly 420 corresponds to the third surface 903.

[0163] After the material stack 90 is conveyed to the cutting position, the second positioning component 820, through the second positioning member 822, can drive the second cutting component 420 to move towards the third surface 903, so that the second cutting component 420 can be aligned with the third surface 903, thereby controlling the second cutting component 420 to cut the third surface 903. After the cutting is complete, the second positioning component 820 can drive the second cutting component 420 away from the third surface 903.

[0164] See Figure 1 and Figure 6 In one embodiment, the second cutting assembly 420 includes a second support member 421, a second cutting drive member 422, and a second heating cutter 423. The second cutting drive member 422 is disposed on the second mounting member 410. The second support member 421 is movably disposed on the second mounting member 410 along a second direction and is connected to the output end of the second cutting drive member 422. The second heating cutter 423 is disposed on the second support member 421 along a first direction. The second cutting drive member 422 is disposed on the frame 100 and can drive the second support member 421 to move along the second direction, so that the second heating cutter 423 heats and cuts the third surface 903 or the fourth surface 904.

[0165] The second support member 421 is a component that supports the second cutting assembly 420. The second support member 421 is disposed on the second mounting member 410 along a first direction. The second heating and cutting member 423 is disposed on the surface of the second support member 421 facing the material stack 90. ​​The second cutting drive member 422 is the power source for the second cutting assembly 420. The second cutting drive member 422 is disposed on the second mounting member 410, and its output end is connected to the second support member 421. Optionally, the second support member 421 may be a support plate or a support frame, etc.

[0166] In this way, the second cutting drive 422 can drive the second support 421 to move relative to the second mounting member 410 and the second positioning assembly 820 along the second direction. As the second support 421 moves, it can drive the second heating cutter 423 toward or away from the third surface 903 to cut the third surface 903. Thus, after the first positioning assembly 810 and the second positioning assembly 820 position the stack 90, a certain distance exists between the second cutting assembly 420 and the third surface 903, preventing cutting from occurring without proper positioning.

[0167] After the material stack 90 is positioned at the cutting position, the second cutting drive 422 drives the second support 421 to move along the second direction, so that the second heated cutting element 423 can cut the third surface 903. After the cutting is completed, the second cutting drive 422 drives the second support 421 to move the second heated cutting element 423 back to the initial position, and then controls the second positioning component 820 to move away from the third surface 903.

[0168] The second heating and cutting element 423 is electrically connected to the control host, which can control the second heating and cutting element 423 to be energized or de-energized. After being energized, the second heating and cutting element 423 can perform thermal melting cutting on the third surface 903. Optionally, the second heating and cutting element 423 is a heating wire. Of course, in other embodiments of this application, the second heating and cutting element 423 may also be blade-shaped or other shapes.

[0169] See Figure 6 In one embodiment, the second cutting assembly 420 further includes a second slide rail and a second slider. The second slide rail is disposed on the second mounting member 410 along a second direction, and the second slider is slidably disposed on the second slide rail and connected to the second support member 421. Thus, when the second cutting drive member 422 drives the second support member 421 to move along the second direction, the second support member 421 can drive the second slider to move along the second slide rail, so that the second cutting assembly 420 can accurately approach or move away from the third surface 903 along the second direction.

[0170] See Figure 6In one embodiment, the second cutting assembly 420 further includes a second tensioning member 424, one end of which is connected to the second support member 421, and the other end of which is connected to the second heated cutting member 423. The second tensioning member 424 can tension the second heated cutting member 423 to keep it in a straight state, thereby ensuring the cutting effect on the third surface 903 and the fourth surface 904.

[0171] Optionally, the second tensioning member 424 is a combination of a spring and a pull rod. Of course, in other embodiments of this application, the second tensioning member 424 may also be a tensioning wheel or other structure capable of tensioning the second heated cutting member 423.

[0172] See Figure 6 In one embodiment, the second cutting mechanism 400 further includes a second adsorption component 430, which is disposed on the second support member 421 along a second direction. The second adsorption component 430 is used to adsorb the third surface 903 or the fourth surface 904. The second adsorption component 430 is disposed on the second support member 421 and extends toward the stack 90.

[0173] The second adsorption component 430 can adsorb the third surface 903 or the fourth surface 904. Before the second heating and cutting element 423 cuts the third surface 903, the second adsorption component 430 adsorbs the third surface 903. This facilitates the second heating and cutting element 423 in cutting the third surface 903 and also avoids damage to the packaging in the stack 90 by the second heating and cutting element 423.

[0174] See Figure 7 and Figure 8 In one embodiment, the second adsorption assembly 430 includes a second adsorption box 431 and a plurality of second adsorption elements 432. The second adsorption box 431 is disposed on the second support member 421, and the plurality of second adsorption elements 432 are disposed on the surface of the second adsorption box 431 facing the material stack 90 and are connected to the second adsorption box 431. The second adsorption box 431 can be connected to an external negative pressure source to control the second adsorption elements 432 to perform adsorption operations.

[0175] After the second cutting drive 422 drives the second heating cutter 423 to align with the third surface 903, the negative pressure source evacuates each of the second adsorption elements 432 through the second adsorption box 431, so that the second adsorption elements 432 can be adsorbed onto the third surface 903, which facilitates the subsequent cutting of the third surface 903 by the second heating cutter 423. Optionally, the second cutting drive 422 is a motor or a cylinder.

[0176] Optionally, the second adsorption element 432 is a vacuum suction cup. The host control controls the second adsorption element 432 to perform adsorption or release actions. Of course, in other embodiments of this application, the second adsorption element 432 may also be a pneumatic adsorption element or an electric adsorption element, etc., which will not be described in detail here.

[0177] See Figure 6 In one embodiment, the second adsorption assembly 430 further includes a second adsorption drive 433, which is disposed on the second support 421 and has its output end connected to the second adsorption box 431. The second adsorption drive 433 can drive the second adsorption box 431 to move multiple second adsorption elements 432 along a second direction, so that the second adsorption elements 432 can approach or move away from the third surface 903 or the fourth surface 904 to adsorb or release the third surface 903 or the fourth surface 904. Optionally, the second adsorption drive 433 is a motor or a cylinder.

[0178] See Figure 1 and Figure 9 In one embodiment, the third cutting mechanism 500 includes a third mounting member 510 and a third cutting assembly 520. The third mounting member 510 is disposed on the frame 100 and located above the conveying mechanism 200. The third cutting assembly 520 is disposed on the third mounting member 510 along a first direction and extends toward the top surface 905 of the stack 90. Figure 9 for Figure 1 A schematic diagram of the third cutting mechanism 500 in the automatic packaging film cutting device 10 shown.

[0179] The third mounting component 510 is a component that supports the third cutting mechanism 500. The third mounting component 510 is mounted on the top support frame 120 of the frame 100 and located above the conveying mechanism 200. Thus, after the material stack 90 is pushed to the cutting position, the third cutting mechanism 500 can be positioned above the material stack 90 to cut the top surface 905 of the material stack 90. ​​In this embodiment, the third mounting component 510 is a mounting frame. Of course, in other embodiments of this application, the third mounting component 510 can also be a mounting plate, a mounting column, or other structures capable of mounting the third cutting mechanism 500.

[0180] The third cutting assembly 520 is the main component for cutting the packaging film. It is positioned below the third mounting member 510 and can move up and down relative to the third mounting member 510 (in a third direction). After the stack 90 is conveyed to the cutting position, the third cutting assembly 520 can descend relative to the third mounting member 510, aligning itself with the top surface 905 to cut it. After cutting, the third cutting assembly 520 can rise relative to the third mounting member 510 to move away from the top surface 905.

[0181] See Figure 1 and Figure 9 In one embodiment, the third cutting assembly 520 includes a third support member 521, a third cutting drive member 522, and a third heating cutting member 523. The third cutting drive member 522 is disposed on the third mounting member 510. The third support member 521 is disposed on the output end of the third heating cutting member 523 and can move along the third third direction with the third heating cutting member 523. The third heating cutting member 523 is disposed on the third support member 521 along the first direction. The third cutting drive member 522 can drive the third support member 521 to move along the third third direction, so that the third heating cutting member 523 cuts the top surface 905.

[0182] The third support member 521 is a component that supports the third cutting assembly 520. The third support member 521 is disposed on the third mounting member 510 along the first direction. The third heating and cutting member 523 is disposed on the surface of the third support member 521 facing the material stack 90. ​​The third cutting drive member 522 is the power source of the third cutting assembly 520. The third cutting drive member 522 is disposed on the third mounting member 510, and its output end is connected to the third support member 521.

[0183] In this way, the third cutting drive 522 can drive the third support 521 to move relative to the third mounting member 510 in a third direction. Consequently, when the second support 421 moves, it can drive the third heated cutting member 523 toward or away from the top surface 905 to cut the top surface 905. Thus, the third heated cutting member 523 can only descend during cutting, avoiding interference with the pushing of the stack 90 and preventing cutting from occurring without proper positioning.

[0184] The third heating and cutting element 523 is electrically connected to the control host, which can control the third heating and cutting element 523 to be powered on or off. After being powered on, the third heating and cutting element 523 can perform thermal melting cutting on the top surface 905. Optionally, the third heating and cutting element 523 is a heating wire. Of course, in other embodiments of this application, the third heating and cutting element 523 may also be blade-shaped or other shapes.

[0185] See Figure 9 In one embodiment, the third cutting assembly 520 further includes a first slider 524, which guides and connects the third support 521 and the third mounting member 510 along a third direction. When the third cutting drive 522 drives the third support 521 to move along a third direction, the third support 521 can drive the first slider 524 to move, so that the third cutting assembly 520 can accurately move closer to or further away from the top surface 905 along a third direction.

[0186] In this embodiment, the first sliding member 524 is a linear bearing. Of course, in other embodiments of this application, the first sliding member 524 may also be a guide rod and a guide hole, or a sliding rail and slider mating structure.

[0187] See Figure 9 In one embodiment, the third cutting assembly 520 further includes a third tensioning member 525, one end of which is connected to the third support member 521, and the other end of which is connected to the third heating cutting member 523. The third tensioning member 525 can tension the third heating cutting member 523 to keep it in a straight state, thereby ensuring the cutting effect on the third surface 903 and the fourth surface 904.

[0188] Optionally, the third tensioning member 525 is a combination of a spring and a pull rod. Of course, in other embodiments of this application, the third tensioning member 525 may also be a tensioning wheel or other structure capable of tensioning the third heated cutting member 523.

[0189] See Figure 9 In one embodiment, the third cutting mechanism 500 further includes a third adsorption component 530, which is disposed on the third mounting member 510 along a first direction and is used to adsorb the top surface 905. The third adsorption component 530 is disposed on the third mounting member 510 and extends toward the stack 90.

[0190] The third adsorption component 530 can adsorb the top surface 905. Before the third heating and cutting element 523 cuts the top surface 905, the top surface 905 is first adsorbed by the third adsorption component 530. This makes it easier for the third heating and cutting element 523 to cut the top surface 905, and at the same time, it can also prevent the third heating and cutting element 523 from damaging the packaging in the stack 90.

[0191] Of course, the third adsorption component 530 can also be disposed on the third support member 521. In this embodiment, there are two sets of the third adsorption components 530, located on both sides of the first cutting component 330; of course, there can also be one set or other quantities of the third adsorption components 530.

[0192] See Figure 9 In one embodiment, the third adsorption assembly 530 includes a third adsorption box 531 and a plurality of third adsorption elements 532. The third adsorption box 531 is disposed on the third mounting member 510, and the plurality of third adsorption elements 532 are disposed on the surface of the third adsorption box 531 facing the material stack 90 and are connected to the third adsorption box 531. The third adsorption box 531 can be connected to an external negative pressure source to control the third adsorption elements 532 to perform adsorption operations.

[0193] After the third cutting drive 522 drives the third heating and cutting component 523 to align with the third surface 903, the negative pressure source evacuates each of the third adsorption components 532 through the third adsorption box 531, so that the third adsorption components 532 can be adsorbed onto the top surface 905, which facilitates the subsequent cutting of the top surface 905 by the third heating and cutting component 523. Optionally, the third cutting drive 522 is a motor or a cylinder.

[0194] Optionally, the third adsorption element 532 is a vacuum suction cup. The host control controls the third adsorption element 532 to perform adsorption or release actions. Of course, in other embodiments of this application, the third adsorption element 532 may also be a pneumatic adsorption element or an electric adsorption element, etc., which will not be described in detail here.

[0195] See Figure 9 In one embodiment, the third adsorption assembly 530 further includes a third adsorption drive 533, which is disposed on the third support 521 and has its output end connected to the adsorption third adsorption box 531. The third adsorption drive 533 can drive the third adsorption box 531 to move multiple third adsorption elements 532 along a third direction, so that the third adsorption elements 532 can approach or move away from the top surface 905 to adsorb or release the top surface 905. Optionally, the third adsorption drive 533 is a motor or a cylinder.

[0196] See Figure 1 and Figure 10 In one embodiment, the fourth cutting mechanism 600 includes a fourth mounting member 610, a second driver 620, and a fourth cutting component 630. The fourth mounting member 610 is disposed along a third direction, the second driver 620 is disposed on the fourth mounting member 610, and the fourth cutting component 630 is disposed at the output end of the second driver 620 and moves with the second driver 620, so that the fourth cutting component 630 moves away from the first surface 901. Figure 10 for Figure 1 A schematic diagram of the fourth cutting mechanism 600 in the automatic packaging film cutting device 10 shown.

[0197] The fourth mounting component 610 is a component that supports the installation of the fourth cutting mechanism 600. The fourth mounting component 610 is arranged along a third direction and located on the left side of the cutting position. The fourth cutting assembly 630 can be mounted on the frame 100 or the conveying mechanism 200, or it can be mounted on the mounting surface. The second driver 620 is mounted on the fourth mounting component 610, and its output end is connected to the fourth cutting assembly 630.

[0198] Furthermore, the fourth cutting assembly 630 is the main component for cutting the packaging film. The fourth cutting assembly 630 is also rotatably connected to the fourth mounting member 610. The second driver 620 can drive the fourth cutting assembly 630 to rotate around the fourth mounting member 610, so that the fourth cutting assembly 630 can move closer to or away from the first surface 901, thereby enabling it to cut the first surface 901 in a third direction.

[0199] When the fourth cutting mechanism 600 is not cutting, it is located in front of the conveying mechanism 200 and does not extend above the conveying mechanism 200, thus not obstructing the stack 90. ​​The stack 90 is pushed to the cutting position, and then the second driver 620 drives the fourth cutting assembly 630 to rotate relative to the fourth mounting member 610 so that the fourth cutting assembly 630 can correspond to the first surface 901.

[0200] In this way, the fourth cutting component 630 can cut the first surface 901. After cutting, the second driver 620 drives the fourth cutting component 630 away from the first surface 901. At this time, the fourth cutting mechanism 600 will not obstruct the stack 90, which facilitates the subsequent pushing of the stack 90.

[0201] Optionally, the second driver 620 is a motor or a cylinder. Optionally, the second driver 620 is rotatably connected to the fourth cutting assembly 630 via a connecting rod, and the fourth cutting assembly 630 can also be rotatably connected to the fourth mounting member 610 via a connecting rod. Optionally, the fourth mounting member 610 is a column. Of course, in other embodiments of this application, the fourth mounting member 610 can also be a fixed bracket, etc.

[0202] See Figure 1 and Figure 10 In one embodiment, the fourth cutting assembly 630 includes a fourth support member 631, a fourth heating and cutting member 632, and two fourth cutting drive members 633. The fourth support member 631 is rotatably connected to the fourth mounting member 610 along a third direction and is disposed at the output end of the second driver 620. The two fourth cutting drive members 633 are spaced apart from the fourth support member 631 along a third direction and are capable of outputting movement along a first direction. The two ends of the fourth heating and cutting member 632 are respectively connected to the output ends of the fourth cutting drive members 633 and move with the fourth cutting drive members 633.

[0203] The fourth support member 631 is a component that supports the fourth cutting assembly 630. The fourth support member 631 extends in a third direction and is rotatably connected to the fourth mounting member 610. Furthermore, the fourth support member 631 is also rotatably connected to the second driver 620. The second driver 620 can drive the fourth support member 631 to rotate around the fourth mounting member 610. Optionally, the fourth support member 631 may be a support plate or support frame, etc., and is rotatably connected to the fourth mounting member 610 via a connecting rod or adapter plate, etc.

[0204] The fourth cutting drive member 633 serves as the power source for the fourth heating and cutting member 632. Two fourth cutting drive members 633 are spaced apart on the fourth support member 631 along a third direction. The top of the fourth heating and cutting member 632 is connected to the upper fourth cutting drive member 633, and the bottom of the fourth heating and cutting member 632 is connected to the lower fourth cutting drive member 633. The fourth cutting drive member 633 is movable relative to the fourth support member 631 along a first direction. In this way, the fourth cutting drive member 633 can drive the fourth heating and cutting member 632 to move along the first direction to approach or move away from the first surface 901, thereby achieving cutting of the first surface 901.

[0205] After the material stack 90 is positioned at the cutting position, the second driver 620 drives the fourth support member 631 to rotate around the fourth mounting member 610, so that the fourth support member 631 drives the fourth heated cutting member 632 to move towards the first surface 901. When the fourth cutting assembly 630 moves into position, the fourth cutting drive member 633 drives the fourth heated cutting member 632 to move towards the first surface 901 to cut the first surface 901. After cutting is completed, the second driver 620 drives the second cutting assembly 420 back to the initial position.

[0206] The fourth heating and cutting element 632 is electrically connected to the control host, which can control the fourth heating and cutting element 632 to be powered on or off. When powered on, the fourth heating and cutting element 632 can perform thermal melting cutting on the first surface 901. Optionally, the fourth heating and cutting element 632 is a heating wire. Of course, in other embodiments of this application, the fourth heating and cutting element 632 may also be blade-shaped or other shapes.

[0207] See Figure 10 In one embodiment, the fourth cutting assembly 630 further includes a second sliding member, which guides and connects the fourth cutting drive member 633 and the fourth heating cutting member 632 along a first direction. When the fourth cutting drive member 633 drives the fourth heating cutting member 632 to move along the first direction, the fourth heating cutting member 632 can drive the second sliding member to move, so that the fourth cutting assembly 630 can accurately approach or move away from the first surface 901 along the first direction.

[0208] In this embodiment, the second sliding member is a linear bearing. Of course, in other embodiments of this application, the second sliding member may also be a guide rod and a guide hole, or a slide rail and slider mating structure.

[0209] See Figure 10 In one embodiment, the fourth cutting assembly 630 further includes a fourth tensioning member 634. One end of the fourth tensioning member 634 is connected to the output end of the fourth cutting drive member 633, and the other end of the fourth tensioning member 634 is connected to the fourth heating cutting member 632. The fourth tensioning member 634 can tension the fourth heating cutting member 632 to keep the fourth heating cutting member 632 in a straight state, thereby ensuring the cutting effect on the first surface 901.

[0210] Optionally, the fourth tensioning member 634 is a combination of a spring and a pull rod. Of course, in other embodiments of this application, the fourth tensioning member 634 may also be a tensioning wheel or other structure capable of tensioning the fourth heated cutting member 632.

[0211] See Figure 10 In one embodiment, the fourth cutting mechanism 600 further includes a fourth adsorption component 640, which is disposed in a third direction on the fourth cutting component 630 and is used to adsorb the first surface 901. The fourth adsorption component 640 is disposed on the fourth support member 631 and extends toward the stack 90.

[0212] The fourth adsorption component 640 can adsorb the first surface 901. Before the fourth heating and cutting element 632 cuts the first surface 901, the first surface 901 is first adsorbed by the fourth adsorption component 640. This makes it easier for the fourth heating and cutting element 632 to cut the first surface 901, and at the same time, it can also prevent the fourth heating and cutting element 632 from damaging the packaging in the stack 90.

[0213] See Figure 10 In one embodiment, the fourth adsorption assembly 640 includes a fourth adsorption box 641 and a plurality of fourth adsorption elements 642. The fourth adsorption box 641 is disposed on the fourth support member 631, and the plurality of fourth adsorption elements 642 are disposed on the surface of the fourth adsorption box 641 facing the material stack 90 and are connected to the fourth adsorption box 641. The fourth adsorption box 641 can be connected to an external negative pressure source to control the fourth adsorption elements 642 to perform adsorption operations.

[0214] After the fourth cutting drive 633 drives the fourth heating cutter 632 to align with the first surface 901, the negative pressure source evacuates each of the fourth adsorption components 642 through the fourth adsorption box 641, so that the fourth adsorption components 642 can be adsorbed onto the first surface 901, facilitating the subsequent cutting of the first surface 901 by the fourth heating cutter 632. Optionally, the fourth cutting drive 633 is a motor or a cylinder.

[0215] Optionally, the fourth adsorption element 642 is a vacuum suction cup. The host control controls the fourth adsorption element 642 to perform adsorption or release actions. Of course, in other embodiments of this application, the fourth adsorption element 642 may also be a pneumatic adsorption element or an electric adsorption element, etc., which will not be described in detail here.

[0216] See Figure 10 In one embodiment, the fourth adsorption assembly 640 further includes a fourth adsorption drive 643, which is disposed on the fourth support member 631, and its output end is connected to the fourth adsorption box 641. The fourth adsorption drive 643 can drive the fourth adsorption box 641 to move multiple fourth adsorption elements 642 along a first direction, so that the fourth adsorption elements 642 can approach or move away from the first surface 901 to adsorb or release the first surface 901. Optionally, the fourth adsorption drive 643 is a motor or a cylinder.

[0217] See Figure 1 and Figure 11 In one embodiment, the plurality of cutting mechanisms further includes at least a fifth cutting mechanism 700, which is located above the conveying mechanism 200 and spaced apart from the first cutting mechanism 300 along a third direction. The fifth cutting mechanism 700 is used to cut the first surface 901 and the second surface 902 of the stack 90 along a second direction. Figure 11 for Figure 1 A schematic diagram of the fifth cutting mechanism 700 in the automatic packaging film cutting device 10 shown.

[0218] The fifth cutting mechanism 700 is located above the first cutting mechanism 300 and can cut the first surface 901 and the second surface 902 along the second direction, forming a seventh slit 913 on the first surface 901 and an eighth slit 922 on the second surface 902. The seventh slit 913 is parallel to the first slit 911, and the eighth slit 922 is parallel to the second slit 921. This achieves effective cutting of the packaging film, facilitating subsequent destacking and unloading operations.

[0219] The fifth cutting mechanism 700 is disposed on the top support frame 120 of the frame 100 and can extend toward the left and right sides of the stack 90 to correspond to the first surface 901 and the second surface 902. When the fifth cutting mechanism 700 is not cutting, it is located above the stack 90, so that the fifth cutting mechanism 700 will not obstruct the stack 90 pushed by the conveying mechanism 200.

[0220] After the stack 90 is pushed to the cutting position, the fifth cutting mechanism 700 moves relative to the frame 100, allowing it to move to the left and right sides of the stack 90. ​​At this point, the fifth cutting mechanism 700 can align with the first surface 901 and the second surface 902, thus cutting the first surface 901 and the second surface 902. After cutting, the fifth cutting mechanism 700 moves again relative to the frame 100, moving away from the stack 90 to facilitate the pushing away of the cut stack 90 and the transport of the stack 90 to be cut to the cutting position.

[0221] See Figure 10 and Figure 11 In one embodiment, the fifth cutting mechanism 700 includes a fifth mounting member 710, a third driver 720, and two sets of fifth cutting components 730. The fifth mounting member 710 is disposed on the frame 100 or the third cutting mechanism 500 along the second direction. The third driver 720 is disposed on the frame 100. The two sets of fifth cutting components 730 are symmetrically and rotatably connected to the fifth mounting member 710 and disposed at the output end of the third driver 720. They move with the third driver 720 so that the fifth cutting components 730 correspond to or move away from the first surface 901 or the second surface 902.

[0222] The fifth mounting component 710 is a component that supports the fifth cutting mechanism 700. The fifth mounting component 710 is fixedly mounted on the top support frame 120 of the frame 100 and located above the cutting position. Two sets of fifth cutting assemblies 730 are symmetrically arranged on the fifth mounting component 710 along a first direction and are rotatably mounted on the fifth mounting component 710. A fifth driver is mounted on the fifth mounting component 710, and its output end is connected to the fifth cutting assembly 730.

[0223] The fifth cutting component 730 is the main component for cutting the packaging film, and it is also rotatably connected to the fifth mounting member 710. The third driver 720 can drive the fifth cutting component 730 to rotate around the fifth mounting member 710, so that the fifth cutting component 730 can move closer to or away from the first surface 901 and the second surface 902, thereby being able to cut the first surface 901 and the second surface 902 along the second direction.

[0224] When the fifth cutting mechanism 700 is not cutting, it is located above the conveying mechanism 200 and does not extend to the left or right sides of the stack 90, thus not obstructing the stack 90. ​​The stack 90 is pushed to the cutting position, and then the third driver 720 drives the fifth cutting assembly 730 to rotate relative to the fifth mounting member 710, so that the fifth cutting assembly 730 can correspond to the first surface 901 and the second surface 902.

[0225] In this way, the fifth cutting component 730 can cut the first surface 901 and the second surface 902. After cutting, the second driver 620 drives the fifth cutting component 730 away from the first surface 901 and the second surface 902. At this time, the fifth cutting mechanism 700 will not obstruct the stack 90, which facilitates the subsequent pushing of the stack 90.

[0226] Optionally, the third actuator 720 is a motor or a cylinder. Optionally, the third actuator 720 is rotatably connected to the fifth cutting assembly 730 via a connecting rod, and the fifth cutting assembly 730 can also be rotatably connected to the fifth mounting member 710 via a connecting rod. Optionally, the fifth mounting member 710 is a mounting frame or mounting plate, etc.

[0227] See Figure 11 In one embodiment, the fifth cutting assembly 730 includes a fifth support member 731, a sixth support member 732, a fifth cutting drive member 733, and a fifth heating cutting member 734. The fifth support member 731 is rotatably connected to the fifth mounting member 710 along a second direction and is disposed at the output end of the third driver 720. The fifth cutting drive member 733 is disposed on the fifth support member 731, and the sixth support member 732 is mounted on its output end. The fifth heating cutting member 734 is disposed on the sixth support member 732 along the second direction. The fifth cutting drive member 733 can drive the sixth support member 732 to move along a first direction, so that the fifth heating cutting member 734 cuts the first surface 901 and the second surface 902.

[0228] The fifth support member 731 supports the third cutting assembly 520, and the sixth support member 732 supports the fifth heated cutting member 734. The fifth support member 731 is disposed on the fifth mounting member 710 along the second direction. The fifth cutting drive member 733 is the power source for the fifth cutting assembly 730 and is disposed on the fifth support member 731. The sixth support member 732 is disposed at the output end of the fifth cutting drive member 733 and moves with it. The fifth heated cutting member 734 is disposed on the surface of the sixth support member 732 facing the material stack 90.

[0229] In this way, the fifth cutting drive member 733 can drive the sixth support member 732 to move along the first direction, and the sixth support member 732 can then drive the fifth heating cutter 734 toward or away from the first surface 901 to cut the first surface 901. Thus, the fifth heating cutter 734 can only move toward the first surface 901 during cutting, avoiding interference with the pushing of the stack 90 and preventing cutting from occurring without proper positioning.

[0230] The fifth heating and cutting element 734 is electrically connected to the control host, which can control the fifth heating and cutting element 734 to be powered on or off. When powered on, the fifth heating and cutting element 734 can perform thermal melting cutting on the top surface 905. Optionally, the fifth heating and cutting element 734 is a heating wire. Of course, in other embodiments of this application, the fifth heating and cutting element 734 may also be blade-shaped or other shapes.

[0231] See Figure 11 In one embodiment, the fifth cutting assembly 730 further includes a third slider 735, which guides and connects the fifth support 731 and the sixth support 732 along a first direction. When the fifth cutting drive 733 drives the sixth support 732 to move along the first direction, the sixth support 732 can drive the third slider 735 to move, so that the fifth cutting assembly 730 can accurately approach or move away from the first surface 901 and the second surface 902 along the first direction.

[0232] In this embodiment, the third sliding member 735 is a linear bearing. Of course, in other embodiments of this application, the third sliding member 735 may also be a guide rod and a guide hole, or a slide rail and slider mating structure.

[0233] When cutting packaging film using the automatic packaging film cutting device 10 of this application, the position of the third cutting mechanism 500 is first adjusted according to the parameters of the stack 90. ​​The third driver 720 is driven so that the third cutting assembly 520 can rise and fall to the set position according to the set parameters, thus preventing the third cutting mechanism 500 from blocking the conveying mechanism 200 from pushing the stack 90 to the cutting position.

[0234] After the position of the third cutting mechanism 500 is adjusted, the first positioning component 810 in the control positioning mechanism 800 rises. The first positioning drive 811 drives the first positioning component 812 to rise. After the first positioning component 812 rises, the first positioning drive 811 stops. Subsequently, the conveying mechanism 200 pushes the stack 90 along the first direction.

[0235] When the stack 90 is conveyed to the first positioning member 812, the first positioning member 812 can block the stack 90, indicating that the stack 90 has been conveyed to the cutting position, and the conveying mechanism 200 stops. Subsequently, the two second positioning components 820 of the positioning mechanism 800 position and clamp the stack 90. ​​The second positioning drive member 821 drives the second positioning member 822 to move toward the stack 90. ​​When the second positioning member 822 abuts against the third surface 903 and the fourth surface 904 of the stack 90, the stack 90 is clamped, and the second positioning drive member 821 stops working.

[0236] After the stack 90 is positioned, the second cutting mechanism 400 is driven to cut the third surface 903 and the fourth surface 904. The second cutting mechanism 400 moves a certain distance toward the stack 90 along with the second positioning component 820. Subsequently, the second adsorption component 430 is driven to attach the second adsorption member 432 to the packaging film, thereby adsorbing the second adsorption member 432 onto the third surface 903 and the fourth surface 904. Then, the second adsorption member 432 adsorbs the packaging film in a direction away from the stack 90.

[0237] Subsequently, the second cutting drive 422 drives the second heating cutter 423 to move toward the third surface 903 and the fourth surface 904, attaching the second heating cutter 423 to the third surface 903 and the fourth surface 904. At the same time, the control host supplies power to the second heating cutter 423 so that the second heating cutter 423 heats up within a set time and cuts the third surface 903 and the fourth surface 904, forming a third slit 931 on the third surface 903 and a fourth slit 941 on the fourth surface 904.

[0238] After cutting is completed, the second heating and cutting element 423 is de-energized, and the second cutting drive element 422 drives the second heating and cutting element 423 away from the material stack 90, causing the second heating and cutting element 423 to reset. The second adsorption assembly 430 releases the packaging film and resets in a direction away from the material stack 90. ​​In this way, the second cutting mechanism 400 completes the cutting of the third surface 903 and the fourth surface 904, and the second cutting mechanism 400 resets.

[0239] The first cutting mechanism 300 cuts the first surface 901 and the second surface 902 of the stack 90. ​​The first driver 320 drives the first mounting member 310 to rotate the two sets of first cutting components 330, causing the two sets of first cutting components 330 to move to the left and right sides of the stack 90 respectively. At this time, the first cutting components 330 are in position. Then, the first adsorption component 340 is driven to attach the first adsorption element 342 to the packaging film, thereby adsorbing the first adsorption element 342 onto the first surface 901 and the second surface 902. Subsequently, the first adsorption element 342 adsorbs the packaging film in a direction away from the stack 90.

[0240] Subsequently, the first cutting drive 332 drives the first heating cutter 333 to move toward the first surface 901 and the second surface 902, attaching the first heating cutter 333 to the first surface 901 and the second surface 902. At the same time, the control host supplies power to the first heating cutter 333 so that the first heating cutter 333 heats up within a set time and cuts the first surface 901 and the second surface 902, forming a first slit 911 on the first surface 901 and a second slit 921 on the second surface 902.

[0241] After cutting is completed, the first heating element cutting 333 is de-energized, and the first cutting drive 332 drives the first heating cutting element 333 away from the material stack 90, causing the first heating cutting element 333 to reset. The first adsorption assembly 340 releases the packaging film and resets in a direction away from the material stack 90. ​​In this way, the first cutting mechanism 300 completes the cutting of the first surface 901 and the second surface 902, and the first cutting mechanism 300 resets.

[0242] The fifth cutting mechanism 700 cuts the first surface 901 and the second surface 902 of the stack 90 along the second direction, and the fifth cutting mechanism 700 is located above the first cutting mechanism 300. The third driver 720 drives the fifth support member 731 to rotate the corresponding fifth cutting assembly 730, so that the two sets of fifth cutting assemblies 730 move to the left and right sides (descend) of the stack 90 respectively. At this time, the fifth cutting assembly 730 moves into position and is above the first surface 901 and the second surface 902.

[0243] Subsequently, the fifth cutting drive 733 drives the fifth heating cutter 734 to move toward the first surface 901 and the second surface 902, attaching the fifth heating cutter 734 to the first surface 901 and the second surface 902. At the same time, the control host powers on the fifth heating cutter 734 so that the fifth heating cutter 734 heats up within a set time and cuts the first surface 301 and the second surface 902, forming a seventh slit 913 on the first surface 901 and an eighth slit 922 on the second surface 902.

[0244] After cutting is completed, the fifth heating and cutting element 734 is de-energized, and the fifth cutting drive element 733 drives the fifth heating and cutting element away from the material stack 90, so that the fifth heating and cutting element 734 is reset. In this way, the fifth cutting mechanism 700 completes the cutting of the first surface 901 and the second surface 902, and the fifth cutting mechanism 700 is reset (rising).

[0245] The third cutting mechanism 500 is controlled to cut the top surface 905 of the stack 90. ​​The third adsorption assembly 530 is driven to attach the third adsorption member 532 to the packaging film, thereby adsorbing the third adsorption member 532 onto the top surface 905. Subsequently, the third adsorption member 532 adsorbs the packaging film in a direction away from the stack 90.

[0246] Subsequently, the third cutting drive 522 drives the third heating cutter 523 to move toward the top surface 905, attaching the third heating cutter 523 to the top surface 905. At the same time, the control host powers the third heating cutter 523 so that the third heating cutter 523 heats up within a set time and cuts the top surface 905, forming a fifth slit 951 on the top surface 905.

[0247] After cutting is completed, the third heating element cutting 523 is de-energized, and the third cutting drive 522 drives the third heating cutting element 523 away from the material stack 90, causing the third heating cutting element 523 to reset. The third adsorption assembly 530 releases the packaging film and resets in a direction away from the material stack 90. ​​In this way, the third cutting mechanism 500 completes the cutting of the top surface 905, and the third cutting mechanism 500 resets.

[0248] The fourth cutting mechanism 600 cuts the first surface 901 of the stack 90 along a third direction. The second driver 620 drives the fourth cutting assembly 630 to rotate around the fourth mounting member 610, and the fourth cutting assembly 630 moves to the left side of the stack 90, at which point the fourth cutting assembly 630 is in position. Subsequently, the fourth adsorption assembly 640 is driven, so that the fourth adsorption member 642 adheres to the packaging film, and thus the fourth adsorption member 642 adsorbs onto the first surface 901. Subsequently, the fourth adsorption member 642 adsorbs the packaging film in a direction away from the stack 90.

[0249] Subsequently, the fourth cutting drive 633 drives the fourth heating cutter 632 to move toward the first surface 901, attaching the fourth heating cutter 632 to the first surface 901. At the same time, the control host powers the fourth heating cutter 632 so that the fourth heating cutter 632 heats up within a set time and cuts the first surface 901, forming a sixth slit 912 on the first surface 901.

[0250] After cutting is completed, the fourth heating element cutting 632 is de-energized, and the fourth cutting drive 633 drives the fourth heating cutting element 632 away from the material stack 90, causing the fourth heating cutting element 632 to reset. The fourth adsorption assembly 640 releases the packaging film and resets in a direction away from the material stack 90. ​​In this way, the fourth cutting mechanism 600 completes the cutting of the first surface 901, and the fourth cutting mechanism 600 resets.

[0251] After the various surfaces of the stack 90 are cut, the second positioning component 820 moves away from the stack 90 to release it, and the first positioning component 810 descends, no longer obstructing the stack 90. ​​The conveying mechanism 200 pushes the cut stack 90 to the unloading position, completing the cutting of the stack 90. ​​Simultaneously, after the previous stack 90 is cut, the next stack 90 can be conveyed to the cutting position for cutting, achieving continuous conveying of the stack 90 and improving production efficiency.

[0252] It is worth noting that the cutting sequence of the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, the fourth cutting mechanism 600 and the fifth cutting mechanism 700 introduced above is not limited to the above. Cutting can be carried out in other sequences, and some cutting mechanisms can also cut simultaneously without interference.

[0253] The automatic packaging film cutting device 10 of this application, through a first cutting mechanism 300, a second cutting mechanism 400, a third cutting mechanism 500, a fourth cutting mechanism 600, and a fifth cutting mechanism 700, can automatically cut the packaging film of the stack 90 without the need for manual cutting by operators, reducing the labor intensity of operators and lowering production costs. Simultaneously, the cutting mechanisms can control the cutting thickness to avoid scratching the packaging components inside the packaging film, ensuring the performance and appearance integrity of the packaging components, improving cutting efficiency, and facilitating subsequent processing of the stack 90 by subsequent processing equipment.

[0254] Furthermore, the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, the fourth cutting mechanism 600, and the fifth cutting mechanism 700 cut the packaging film through a hot melt cutting method, avoiding the dulling problem that occurs when using ordinary blades for cutting, and thus avoiding the situation of not being able to cut completely. This ensures that the first cutting mechanism 300, the second cutting mechanism 400, the third cutting mechanism 500, the fourth cutting mechanism 600, and the fifth cutting mechanism 700 can accurately cut, thereby improving the cutting stability of the automatic packaging film cutting device 10.

[0255] This application also provides a processing apparatus, including an unloading device, a processing device, and an automatic packaging film cutting device 10 as described above. The automatic packaging film cutting device 10 cuts the packaging film on the outside of the stack 90, the unloading device transfers each package in the stack 90 to the processing device, and the processing device processes each package.

[0256] After adopting the automatic packaging film cutting device 10 of the above embodiment, the processing equipment of this application can realize the automatic cutting of packaging film, which eliminates the need for manual cutting by operators, thereby reducing the labor intensity of operators and improving production efficiency.

[0257] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0258] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
