[0045] Reference Figures 1 to 4 In some embodiments, the present application provides a fully automatic packaging device for flexible packaging materials, comprising:

[0046] Mounting seat 1;

[0047] The material conveying device 2 is arranged on the mounting seat 1, and includes a first conveying section 21 and a second conveying section 22 arranged horizontally and spaced apart, a first channel is formed between the first conveying section 21 and the second conveying section 22, the first channel is for the flexible packaging material to pass through, and the first conveying section 21 and the second conveying section 22 are used to convey the product to be packaged;

[0048] The feeding device 3 is arranged on the mounting seat 1 and is located above the material conveying device 2. The discharge end of the feeding device 3 is arranged toward the first channel. The feeding device 3 is used to carry the material and convey the flexible packaging material to the first channel.

[0049] The material pulling mechanism 4 is provided on the mounting seat 1 and is located below the material conveying device 2. The material pulling mechanism 4 can pass through the first channel to grab the flexible packaging material and drive the grabbed flexible packaging material to move;

[0050] The cutting device 5 is disposed between the material conveying device 2 and the discharge end of the feeding device 3 and is used for cutting the flexible packaging material.

[0051] In this embodiment, the fully automatic packaging device for flexible packaging materials of the present application can be applied to clothing folding equipment. The material conveying device 2 can convey clothing as products to be packaged. The flexible packaging material can be paper or a film wrapped around the clothing, etc., which is only used as an example here.

[0052] The material conveying device 2 conveys the product to be packaged through the first conveying section 21 and the second conveying section 22 horizontally spaced apart on the mounting seat 1, and utilizes the first channel formed therebetween. The first channel allows the flexible packaging material to pass through, providing a basis for subsequently wrapping the flexible packaging material around the product to be packaged.

[0053] The feeding device 3 is arranged on the mounting seat 1 and is located above the material conveying device 2, with its discharge end facing the first channel. Relying on its own function of carrying materials and conveying flexible packaging materials to the first channel, the feeding device 3 continuously provides the flexible packaging materials required for packaging for the packaging operation. Exemplarily, the feeding device 3 can be a conveyor line or a multi-axis handling robot, which is not limited here.

[0054] The material pulling mechanism 4 is located below the material conveying device 2, and can grab the flexible packaging material and drive it to move. Specifically, in the initial state, the material pulling mechanism 4 is first in a standby state, located at the initial position below the material conveying device 2, waiting for the feeding device 3 to convey the flexible packaging material to the top of the first channel, and preparing for the grabbing operation. When the flexible packaging material reaches the designated area, the material pulling mechanism 4 activates the corresponding grabbing component (for example, through the mechanical clamp 42, the adsorption device, etc., depending on its design structure, which is only exemplified here), passes through the first channel to contact and grab the flexible packaging material. After the grabbing is successful, the material pulling mechanism 4 drives the grabbed flexible packaging material to move according to the preset packaging program instructions. For example, according to the length and packaging requirements of the product, the flexible packaging material is pulled in the direction toward the initial position to reach a suitable length, so as to prepare for subsequent cutting and complete wrapping of the product. After completing this stage of movement, the material pulling mechanism 4 will maintain the grabbing state of the packaging material until the cutting device 5 completes the subsequent process links such as the cutting operation.

[0055] When the front end of the product to be packaged reaches the end of the first conveying section 21, a sensor can be set to detect that the product to be packaged is in place. At this time, the cutting device 5 can accurately control the length of the packaging material and cut it at a suitable position. At the same time, the tearing mechanism 4 releases the cut flexible packaging material, and the first conveying section 21 continues to convey the product to be packaged to the second conveying section 22. When the product to be packaged passes through the first channel between the first conveying section 21 and the second conveying section 22, the cut flexible packaging material is driven by the product to be packaged and wrapped around the outside of the product to be packaged, thereby completing the work of the packaging material of an independent packaging unit, and finally realizing the fully automatic packaging of the product to be packaged.

[0056] The present application achieves the following by setting up a fully automatic packaging device for flexible packaging materials of the above structure:

[0057] Beneficial effects:

[0058] First, it improves packaging efficiency: the entire packaging process is automated, and all devices work together without excessive human intervention. Compared with traditional manual packaging or semi-automatic packaging methods, it can package more products per unit time, greatly improving the packaging speed and overall efficiency.

[0059] Secondly, the packaging quality is improved: the feeding device 3, the tearing mechanism 4 and the cutting device 5 can accurately control the conveying amount, stretching condition and cutting position of the flexible packaging material, so that the packaging material amount of each product is appropriate, the wrapping is tight and standardized, and the quality of the packaging is effectively guaranteed, and product damage caused by improper packaging is reduced.

[0060] Third, the packaging flexibility is high. The present application can flexibly adapt to various packaging tasks by adjusting the relevant parameters of each device (such as conveying speed, tearing length, cutting position, etc.) according to the size, shape and packaging requirements of different products, and has a wide range of applications.

[0061] Reference Figure 1 In some embodiments, the first conveying section 21 proposed in the embodiment of the present application includes a first conveying belt 211 and a first driving member 212. The output end of the first driving member 212 is drivingly connected to the first conveying belt 211. The first conveying belt 211 is used to carry the product to be packaged. The first driving member 212 is used to drive the first conveying belt 211 to move so that the product to be packaged moves horizontally toward the second conveying section 22.

[0062] The second conveying section 22 includes a second conveying belt 221 and a second driving member 222. The output end of the second driving member 222 is connected to the second conveying belt 221. The second conveying belt 221 is used to receive the product. The second driving member 222 is used to drive the second conveying belt 221 to move so that the product moves away from the first conveying section 21 in the horizontal direction.

[0063] In this embodiment, first, the product to be packaged is placed on the first conveyor belt 211 of the first conveying section 21. The first conveyor belt 211 provides a stable carrying surface for the product, so that the product can be in a suitable position and wait for subsequent conveying operations.

[0064] The output end of the first driving member 212 is in driving connection with the first conveyor belt 211. When the first driving member 212 is started, it transmits power to the first conveyor belt 211, so that the first conveyor belt 211 starts to move. Since the product is placed on the first conveyor belt 211, under the action of friction, the product moves horizontally toward the second conveyor section 22 along with the movement of the first conveyor belt 211.

[0065] When the product reaches the end of the first conveying section 21 under the action of the first driving member 212 and the first conveying belt 211, the product will naturally transition to the second conveying belt 221 of the second conveying section 22. The second conveying belt 221 plays the role of receiving the product here, ensuring that the product can be smoothly transferred from the first conveying section 21 to the second conveying section 22.

[0066] The output end of the second driving member 222 is in driving connection with the second conveyor belt 221. After the product is received, the second driving member 222 is started to provide power to the second conveyor belt 221 to start moving. The product on the second conveyor belt 221 continues to move horizontally away from the first conveying section 21 under the action of friction. The purpose of this step is to completely convey the product that has been wrapped with packaging materials away from the packaging area to make room for the packaging process of the next product to be packaged.

[0067] Reference Figure 1 and Figure 2 In some embodiments, the feeding device 3 proposed in the embodiment of the present application includes:

[0068] A mounting frame 31, disposed on the mounting seat 1, the mounting frame 31 is formed with a second channel for discharging the flexible packaging material;

[0069] A material-carrying roller 32 is provided on the mounting frame 31 and is used for carrying the flexible packaging material;

[0070] The material feeding driving member 33 is used for carrying the material and rolling and rotating to move the flexible packaging material so as to convey the flexible packaging material to the second passage.

[0071] In this embodiment, the feeding device 3 mainly relies on the bearing function of the material loading roller 32 and the power drive of the material feeding drive 33 to realize the conveying of the flexible packaging material. The material loading roller 32 is used as a carrier for placing the flexible packaging material, and the material feeding drive 33 provides the material loading roller 32 with rotational power.

[0072] When the flexible packaging material is a rolled paper, it can be placed on the loading roller 32. When the loading roller 32 rotates, the rolled flexible packaging material is driven to rotate, or the flexible packaging material can be wound on the loading roller 32. The packaging material will move with the rotation of the loading roller 32, thereby being transported to the second channel of the mounting frame 31.

[0073] The present application achieves the following beneficial effects by providing the feeding device 3 with the above structure:

[0074] The feeding device 3 can stably provide flexible packaging materials for the packaging process. Through the synergistic effect of the feeding drive 33 and the loading roller 32, the packaging materials can be conveyed out at a certain speed and sequence, avoiding interruption or instability of material supply and ensuring the continuity of the packaging process. The design of the loading roller 32 can not only effectively carry the flexible packaging materials, but also keep the materials in a good state during the conveying process. Through a reasonable driving method, the packaging materials can be fully utilized, the waste of materials can be reduced, and the production cost can be reduced.

[0075] Reference Figure 3 In some embodiments, the fully automatic packaging device for flexible packaging materials provided in the embodiment of the present application further includes a tensioning device 6 located between the loading roller 32 and the second channel, and the tensioning device 6 is used to tension the flexible packaging material.

[0076] Furthermore, in some embodiments, the tensioning device 6 proposed in the embodiments of the present application includes multiple tensioning shafts 61, and the multiple tensioning shafts 61 are distributed at intervals in the horizontal direction, and two adjacent tensioning shafts 61 are staggered in the vertical direction. Each tensioning shaft 61 is used for flexible packaging materials to be wound around to tension the flexible packaging materials.

[0077] In the above embodiment, the tensioning shaft 61 can also be called a counterweight bracket, which mainly realizes the tensioning of the flexible packaging material through multiple tensioning shafts 61 that are spaced apart in the horizontal direction and two adjacent tensioning shafts 61 are staggered in the vertical direction. When the packaging material is wound on these tensioning shafts 61, due to the position distribution characteristics of the tensioning shafts 61, the packaging material will change direction when passing through each tensioning shaft 61, which makes the packaging material stretched under the action of its own tension and the friction force with the tensioning shaft 61, thereby achieving the tensioning effect. This design utilizes the flexibility and friction principle of the packaging material, and puts the material in an appropriate tension state through a reasonable layout of the tensioning shafts 61.

[0078] Before the packaging equipment is started, the flexible packaging material is first drawn out from the loading roller 32, and then sequentially wound on a plurality of tensioning shafts 61. The packaging material will pass between the tensioning shafts 61 that are spaced apart in the horizontal direction, and at adjacent tensioning shafts 61, the material will continuously change direction due to the staggered arrangement of the tensioning shafts 61 in the vertical direction.

[0079] As the feeding drive 33 of the feeding device 3 is started, the loading roller 32 starts to rotate and convey the packaging material. When the packaging material moves between the tensioning shafts 61, due to its own elasticity and the friction with the surface of the tensioning shaft 61, the material will be gradually tensioned in the process of passing through each tensioning shaft 61. This tensioning state will be maintained as the packaging material is continuously conveyed, ensuring that the packaging material output from the tensioning device 6 is always at an appropriate tension, so that it can smoothly enter the second channel and be conveyed to the top of the first channel of the material conveying device 2.

[0080] The present application achieves the following beneficial effects by providing the tensioning device 6 of the above structure:

[0081] The tensioning device 6 can effectively prevent the flexible packaging material from becoming loose during the conveying process. By maintaining the appropriate tension of the material, problems such as interruption or uneven feeding caused by loose material are prevented, thereby improving the stability and reliability of feeding. The appropriate tension enables the flexible packaging material to be more accurately grasped and operated by the tearing mechanism 4 when it is conveyed to the packaging position. Loose packaging materials may cause inaccurate grasping positions or wrinkles, deformations, etc. during the packaging process, and the tensioning device 6 can reduce the occurrence of these problems, thereby improving the accuracy and quality of packaging.

[0082] Reference Figure 2In some embodiments, the fully automatic packaging device for flexible packaging materials provided in the embodiments of the present application further includes a clamping mechanism 7, which is disposed on the upper side of the first channel and includes:

[0083] A first clamping member 71, provided on the mounting frame 31;

[0084] A second clamping member 72 is slidably connected to the mounting frame 31, and the second clamping member 72 is horizontally spaced apart from the first clamping member 71;

[0085] A clamping driving member 73 is provided on the mounting frame 31, and an output end of the clamping driving member 73 is connected to the second clamping member 72;

[0086] A third passage for the flexible packaging material to pass through is formed between the first clamping member 71 and the second clamping member 72 , and the clamping drive member 73 is used to drive the first clamping member 71 to abut against or move away from the second clamping member 72 to clamp or release the flexible packaging material in the third passage.

[0087] In this embodiment, the clamping mechanism 7 mainly utilizes the relative movement of the first clamping member 71 and the second clamping member 72 to achieve the clamping or loosening of the flexible packaging material. The first clamping member 71 is fixed on the mounting frame 31, and the second clamping member 72 is slidably connected to the mounting frame 31, and is driven to move by the clamping drive member 73. When the clamping drive member 73 works, it pushes or pulls the second clamping member 72 so that the second clamping member 72 approaches or moves away from the first clamping member 71. The third channel formed between the first clamping member 71 and the second clamping member 72 is used to allow the flexible packaging material to pass through. When the second clamping member 72 approaches the first clamping member 71, the two can apply pressure to the packaging material in the channel and clamp the material by friction; when the second clamping member 72 moves away from the first clamping member 71, the pressure disappears, and the packaging material can pass freely, thereby achieving the effect of loosening.

[0088] Before the packaging process begins, the clamping drive member 73 is in an initial state, and a certain distance is maintained between the second clamping member 72 and the first clamping member 71 to form a third channel through which the flexible packaging material can smoothly pass. At this time, the clamping mechanism 7 does not apply a clamping force to the packaging material.

[0089] When it is necessary to perform a specific operation on the flexible packaging material (such as fixing the position of the material during the cutting operation, or preventing it from moving when adjusting the state of the material, etc.), the clamping drive 73 starts to work. It drives the second clamping member 72 to slide toward the first clamping member 71, and the second clamping member 72 gradually approaches the first clamping member 71. As the distance between the two decreases, the packaging material in the third channel is squeezed, and when a certain pressure is reached, the packaging material is tightly clamped between the first clamping member 71 and the second clamping member 72. In this state, the position of the packaging material is fixed, and subsequent precise operations can be performed.

[0090] When the specific operation is completed, the clamping driving member 73 drives the second clamping member 72 to slide away from the first clamping member 71, and the distance between the first clamping member 71 and the second clamping member 72 gradually increases, and the pressure on the packaging material decreases accordingly. When the distance reaches a certain level, the packaging material is no longer constrained by sufficient friction and can pass freely in the third channel. At this time, the clamping mechanism 7 completes the loosening action, and the packaging material can continue to flow normally in the device to proceed to the next packaging process.

[0091] The present application achieves the following beneficial effects by setting the clamping mechanism 7 of the above structure:

[0092] The clamping mechanism 7 can accurately fix the position of the flexible packaging material when needed. In the key steps of the packaging process (such as the cutting operation), the clamping material can prevent it from being displaced during the force (such as the force of the cutting knife), thereby ensuring the accuracy of the cutting position and helping to improve the accuracy and quality of the packaging.

[0093] Reference Figure 2 In some embodiments, the cutting mechanism proposed in the embodiment of the present application is arranged between the clamping mechanism 7 and the first channel, and includes:

[0094] A first cutter 51 and a second cutter 52, the first cutter 51 and the second cutter 52 are horizontally spaced and both are slidably connected to the mounting frame 31, and a fourth channel for the flexible packaging material to pass through is formed between the first cutter 51 and the second cutter 52;

[0095] The cutting drive member 53 is disposed on the mounting frame 31 , and the output end of the cutting drive member 53 is connected to the first cutter 51 and the second cutter 52 to drive the first cutter 51 and the second cutter 52 to move toward or away from each other to cut the flexible packaging material.

[0096] In this embodiment, the cutting mechanism mainly relies on the relative movement of the first cutter 51 and the second cutter 52 to cut the flexible packaging material. The first cutter 51 and the second cutter 52 are arranged horizontally at intervals and slidably connected to the mounting frame 31, and the fourth channel formed between them is used to allow the packaging material to pass through. The cutting drive 53 is installed on the mounting frame 31, and its output end is connected to the first cutter 51 and the second cutter 52. When the cutting drive 53 is working, it drives the first cutter 51 and the second cutter 52 to move toward each other, so that the two cutters gradually approach each other, and use the sharp edges of the cutters to apply shear force to the packaging material in the fourth channel, thereby cutting the material; when the cutters move away from each other, the fourth channel is opened, and the packaging material can pass normally, preparing for the next cutting.

[0097] When the packaging process is carried out normally, the cutting drive member 53 is in the initial state, and a certain distance is maintained between the first cutter 51 and the second cutter 52 to form a fourth channel, through which the flexible packaging material can pass smoothly. At this time, the cutting mechanism does not cut the packaging material.

[0098] When the packaging process reaches a stage where the packaging material needs to be cut (for example, when the packaging material is stretched to a suitable length, or when the product reaches a specific location and needs to be wrapped), the cutting drive 53 starts to work. It drives the first cutter 51 and the second cutter 52 to move toward each other, and the two cutters approach each other along the mounting frame 31. As the cutters approach, the shear force generated on the packaging material located in the fourth channel gradually increases. When the blade of the cutter contacts and cuts into the packaging material, the packaging material is cut under the action of the shear force. In this process, since the movement of the cutter is precisely controlled by the cutting drive 53, the packaging material can be accurately cut at the desired position.

[0099] After the packaging material is cut, the cutting drive 53 drives the first cutter 51 and the second cutter 52 to move in opposite directions, so that the two cutters return to the initial spacing and reopen the fourth channel. In this way, subsequent packaging materials can continue to pass through the fourth channel to prepare for the next cutting operation.

[0100] Reference Figure 4 In some embodiments, the material tearing mechanism proposed in the embodiment of the present application includes:

[0101] A base 41 is provided on the mounting base 1;

[0102] A clamping jaw 42 is slidably connected to the base 41, the clamping jaw 42 is arranged corresponding to the first channel, and the clamping jaw 42 is used to clamp the flexible packaging material;

[0103] The material pulling driving member 43 is arranged on the mounting base 1 , and the output end of the material pulling driving member 43 is connected to the clamping jaw 42 to drive the clamping jaw 42 to move in the vertical direction, so that the clamping jaw 42 passes through the first channel and moves toward the discharging end of the feeding device 3 .

[0104] In this embodiment, the material pulling mechanism mainly realizes the grabbing and pulling of the flexible packaging material by driving the clamping jaw 42 to move in the vertical direction through the material pulling driving member 43. The base 41 provides a stable support base for the entire mechanism. The clamping jaw 42 is slidably connected to the base 41 and can move up and down in the vertical direction under the action of the material pulling driving member 43. The clamping jaw 42 is set corresponding to the first channel and can grab the packaging material at a suitable position. When the material pulling driving member 43 is working, it transmits power to the clamping jaw 42, so that the clamping jaw 42 rises in the vertical direction, thereby passing through the first channel to move toward the discharge end of the feeding device 3 to clamp the flexible packaging material extending from the discharge end of the feeding device 3. After clamping, the material pulling driving member 43 drives the clamping jaw 42 to move in the vertical direction, so that the clamping jaw 42 returns along the original path with the flexible packaging material that has been grabbed and passes through the first channel. In this process, the material pulling driving member 43 can accurately control the movement speed and stroke of the clamping jaw 42 to control the movement speed and pull-out length of the flexible packaging material.

[0105] After the packaging material is brought into the first channel, the clamp 42 may maintain the gripping state of the packaging material and wait for further operation instructions (for example, it is necessary to maintain the grip when cooperating with the cutting device 5 to perform a cutting operation) according to the specific needs of the subsequent packaging process, or release the packaging material according to a set process, and then return to the initial position in the vertical direction under the drive of the material pulling drive 43, preparing for the next round of gripping, pulling and material bringing operations, thereby realizing a cyclical packaging process.

[0106] Reference Figure 4 In some embodiments, the fully automatic packaging device for flexible packaging materials provided in the embodiments of the present application further includes:

[0107] A slide rail 8, provided on the base 41;

[0108] The slide block 9 is slidably connected to the slide rail 8 , and the clamping claw 42 is disposed on the slide block 9 .

[0109] In this embodiment, the combination of the slide rail 8 and the slider 9 provides a precise movement path for the clamp 42. The slide rail 8 is formed with a fixed track shape and direction, and the slider 9 can only slide along the direction specified by the slide rail 8. Since the clamp 42 is installed on the slider 9, when the material pulling drive 43 drives the clamp 42 to move, the sliding of the slider 9 on the slide rail 8 can ensure that the clamp 42 moves up and down stably and accurately along the predetermined vertical direction, which can improve the accuracy and repeatability of the movement of the clamp 42, so that the rising and falling positions of the clamp 42 can be accurately controlled each time, thereby ensuring the accuracy of the grabbing and pulling operations of the flexible packaging material, which is conducive to improving the packaging quality and packaging efficiency.
