Description

Technical Field

[0001] The present application relates to the technical field of packaging machinery, and in particular to a material dividing mechanism and an automatic packaging machine. Background Art

[0002] With the development of packaging machine technology, automatic packaging machines have emerged. These machines can simultaneously make bags and convey materials, then pack the materials into finished bags, effectively improving production efficiency. Due to their high packaging efficiency, automatic packaging machines are widely used in various production processes, such as ice production and packaging. Existing automatic packaging machines for ice processing generally feature a divider mechanism that divides the ice delivered from the previous process into multiple portions. Each portion is the same volume as or slightly smaller than the bag's capacity, preventing overflow or bag damage caused by excessive ice.

[0003] In related technologies, the dispensing mechanism typically features an adjustable chamber. Ice cubes are introduced into the chamber, and once the chamber is full, the ice cubes are transferred to the packaging bag. By manually adjusting the chamber's size, the volume of the chamber matches the volume of the packaging bag, ensuring the bag can hold the appropriate amount of ice.

[0004] However, the above-mentioned method of manually adjusting the volume of the receiving chamber requires first releasing the fixings of the material distribution mechanism, such as bolts, before manually adjusting the volume of the receiving chamber. After the volume of the receiving chamber is adjusted to an appropriate size, the material distribution mechanism needs to be fixed again using the fixings for use. The above-mentioned manual adjustment method is time-consuming and labor-intensive, and is difficult to perform when the material distribution mechanism is large in size and weight. Summary of the Invention

[0005] Based on this, it is necessary to provide a material dividing mechanism and an automatic packaging machine that can automatically adjust the volume of the accommodating cavity to address the above-mentioned time-consuming and labor-intensive manual operation problems.

[0006] In one aspect, the present application provides a material distribution mechanism, comprising:

[0007] Dispensing barrel;

[0008] A collecting hopper, connected to the distributing cylinder;

[0009] A rotating shaft, a first rotating member, and a second rotating member, wherein the first rotating member and the second rotating member are both disposed in the distributing barrel and extend from the central axis of the distributing barrel to the inner side wall of the distributing barrel, and the first rotating member and the second rotating member are spaced apart; the rotating shaft is connected to the first rotating member and is used to drive the first rotating member to rotate around the central axis of the distributing barrel, and the first rotating member, the second rotating member, and the inner wall of the distributing barrel enclose a receiving chamber;

[0010] An inflatable shaft is coaxially connected to the rotating shaft. When the inflatable shaft is inflated, the inflatable shaft cooperates with the second rotating member, so that when the rotating shaft drives the first rotating member to rotate, the inflatable shaft drives the second rotating member to rotate synchronously with the first rotating member. When the inflatable shaft is deflated, the inflatable shaft releases the cooperation with the second rotating member, so that the first rotating member and the second rotating member can move relative to each other to adjust the volume of the accommodating chamber.

[0011] In some embodiments, the distributing mechanism further includes a driving member, a driving rack and a driving gear, wherein the driving rack is connected to the distributing barrel, the driving member is provided on one side of the distributing barrel, and the driving gear is connected to the driving member and is used to engage and drive the driving rack to move under the drive of the driving member, so as to drive the distributing barrel to rotate;

[0012] The second rotating member is connected to the inner side wall of the material distributing barrel and moves along with the side wall of the material distributing barrel.

[0013] In some embodiments, the material dispensing mechanism further includes a telescopic mechanism, which is connected to the driving gear and is used to drive the driving gear to move relative to the driving rack, so that the driving gear is engaged with or separated from the driving rack.

[0014] In the above-mentioned material distribution mechanism, the first rotating member and the second rotating member are both arranged in the material distribution barrel and spaced apart. The first rotating member, the second rotating member, and the inner wall of the material distribution barrel enclose a storage chamber, and the collection hopper guides the material into the storage chamber. During use, the pneumatic shaft is inflated, and the rotating shaft drives the first rotating member and the second rotating member to move synchronously. After the material fills the storage chamber, the first rotating member and the second rotating member push the ice cubes in the storage chamber to the subsequent device for processing. When the volume of the storage chamber needs to be adjusted, the pneumatic shaft is deflated, and the rotating shaft drives the first rotating member and the second rotating member to move relative to each other, thereby changing the volume of the storage chamber. After the volume of the storage chamber is adjusted to the appropriate size, the pneumatic shaft is inflated, so that the pneumatic shaft and the second rotating member are re-matched. At this time, the first rotating member and the second rotating member can rotate synchronously, that is, the relative position of the two is fixed, and the volume of the storage chamber can be adjusted. Through the above-mentioned arrangement, the volume of the storage chamber of the material distribution mechanism can be changed without manual adjustment, saving time and effort, improving efficiency, and being able to adapt to material distribution mechanisms of different sizes.

[0015] On the other hand, an automatic packaging machine is provided, which includes the material dividing mechanism as described above; and

[0016] a frame, wherein the material distribution mechanism is connected to the frame;

[0017] An ice crushing mechanism is connected to the frame and is used to process the material processed by the material dividing mechanism. The ice crushing mechanism is provided with a discharge port;

[0018] a film rolling mechanism connected to the frame and used to provide a membrane structure;

[0019] A transmission mechanism connected to the frame, the film rolling mechanism being provided at one end of the transmission mechanism, the transmission mechanism being used to transport the film structure along a transmission direction, and the middle portion of the transmission mechanism being provided corresponding to the discharge port;

[0020] The bag-making mechanism and the packaging mechanism are both arranged corresponding to the transmission mechanism. The bag-making mechanism is arranged between the film-rolling mechanism and the discharge port, and is used to process the film structure into a bag-like structure. The packaging mechanism is arranged between the discharge port and the other end of the transmission mechanism, and is used to seal the bag-like structure.

[0021] A water spray assembly is connected to the frame and is used to inject water into the material distribution mechanism.

[0022] In some embodiments, the ice crushing mechanism includes a housing, a first crushing knife, and a second crushing knife, wherein the length of the first crushing knife is greater than the length of the second crushing knife.

[0023] In some embodiments, the film rolling mechanism includes a film rolling drum, a fiber optic sensor and an alarm assembly, the film rolling drum is rotatably connected to the frame, and the film structure is wound around the outer circumference of the film rolling drum; the fiber optic sensor and the alarm assembly are both connected to the frame, the fiber optic sensor is electrically connected to the alarm assembly, and is used to detect the thickness of the film structure wound around the film rolling drum.

[0024] In some embodiments, the film rolling mechanism further includes a heat sealing mechanism, which is connected to the frame and disposed on a side of the film rolling drum.

[0025] In some embodiments, the transmission mechanism includes at least two conveyor belts, the at least two conveyor belts are arranged in parallel, and the membrane structure is sandwiched between the conveyor belts;

[0026] It also includes a bag opening mechanism, which is arranged corresponding to the discharge port. The bag opening mechanism includes two oppositely arranged guide plates. The two guide plates are movably connected to the frame and can move toward or away from each other. The two guide plates are arranged between the two conveyor belts, and the two conveyor belts are respectively in contact with the side walls opposite to each other of the two guide plates.

[0027] In some embodiments, the automatic packaging machine further includes a shaking mechanism, which is connected to the frame and is arranged corresponding to the bag opening mechanism, for vibrating the bag-like structure located at the bag opening mechanism.

[0028] In some embodiments, the automatic packaging machine further includes an air storage assembly fixed to the frame, wherein the air storage assembly is connected to the shaking mechanism and is used to drive the shaking mechanism.

[0029] The automatic packaging machine, through the provision of a material distribution mechanism, can divide ice cubes into multiple portions of specific volumes. After being distributed by the material distribution mechanism, the materials are sequentially fed into the ice crushing mechanism for thorough crushing, resulting in ice cubes that meet production standards. A film roll device provides a film structure, which is then driven by a conveyor mechanism and passed through a bag-making mechanism. The bag-making mechanism processes the film structure to form a bag-shaped structure. The bag-shaped structure is then moved along the conveyor mechanism to the discharge port, allowing the ice cubes processed by the ice crushing mechanism to fall into the bag-shaped structure through the discharge port. After the bag-shaped structure is filled with material, it is moved along the conveyor mechanism to the packaging mechanism for sealing, completing the material packaging. A water spray assembly is provided to inject water into the material distribution mechanism, flushing any ice cubes remaining in the material distribution mechanism and ice crushing mechanism into the bag-shaped structure, thereby preventing the weight of the ice cubes in the bag from failing to meet production requirements. Through this arrangement, the material distribution mechanism ensures that the volume of material loaded into the bag-shaped structure corresponds to the bag-shaped volume; the ice crushing mechanism crushes the ice cubes to obtain ice cubes of the desired size. The water spray assembly can clean the material dispensing mechanism and the ice crushing mechanism, and clean the crushed ice remaining in the material dispensing mechanism and the ice crushing mechanism.

[0047] See Figure 1 、 Figure 2 and Figure 3 , Figure 1 FIG. 1 shows a schematic diagram of the overall structure of an automatic packaging machine in an embodiment of the present application. Figure 2 The figure shows the disassembled structure of the material distributing mechanism and the ice crushing mechanism in one embodiment of the present application. Figure 3 A disassembled schematic diagram of the internal structure of the material distributing barrel in one embodiment of the present application is shown. On the one hand, one embodiment of the present application provides a material distributing mechanism 100, which includes a material distributing barrel 110, a collecting hopper 120, a rotating shaft 130, a first rotating member 140, a second rotating member 150 and an inflatable shaft 160. Among them, the collecting hopper 120 is connected to the material distributing barrel 110; the first rotating member 140 and the second rotating member 150 are both arranged in the material distributing barrel 110, and both extend from the central axis of the material distributing barrel 110 to the inner side wall of the material distributing barrel 110, and the first rotating member 140 and the second rotating member 150 are spaced apart; the rotating shaft 130 is connected to the first rotating member 140, and is used to drive the first rotating member 140 to rotate around the central axis of the material distributing barrel 110, and the first rotating member 140, the second rotating member 150 and the inner wall of the material distributing barrel 110 enclose a container. The inflatable shaft 160 is coaxially connected to the rotating shaft 130. When the inflatable shaft 160 is inflated, the inflatable shaft 160 cooperates with the second rotating member 150, so that when the rotating shaft 130 drives the first rotating member 140 to rotate, the inflatable shaft 160 drives the second rotating member 150 to rotate synchronously with the first rotating member 140. When the inflatable shaft 160 is deflated, the inflatable shaft 160 releases the cooperation with the second rotating member 150, so that the first rotating member 140 and the second rotating member 150 can move relative to each other to adjust the volume of the accommodating chamber 101.

[0048] The first rotating member 140 and the second rotating member 150 can be provided singly or in corresponding numbers. If multiple first rotating members 140 and multiple second rotating members 150 are provided, the multiple first rotating members 140 and the multiple second rotating members 150 are provided in a one-to-one corresponding manner. Figure 2 、 Figure 3 and Figure 4As shown, preferably, the collecting hopper 120 is provided above the distributing barrel 110, and the collecting hopper 120 is used to convey materials into the distributing barrel 110. The first rotating member 140 includes a first partition 141, and the second rotating member 150 includes a second partition 151. The first partition 141 and the second partition 151 both extend from the central axis of the distributing barrel 110 to the inner side wall of the distributing barrel 110. The sides of the first partition 141 and the second partition 151 with larger areas are arranged along the axial direction of the distributing barrel 110. The first partition 141, the second partition 151 and the inner side wall of the distributing barrel 110 enclose a receiving chamber 101. The materials in the collecting hopper 120 can fall into the receiving chamber 101, so that the materials fill the receiving chamber 101. Therefore, the volume of the materials entering the receiving chamber 101 is determined by the volume of the receiving chamber 101. The rotating shaft 130 is connected to the first rotating member 140 and drives the first rotating member 140 to rotate around the central axis of the distributing barrel 110. The inflatable shaft 160 is arranged on the outer periphery of the rotating shaft 130 or as a part of the rotating shaft 130 (one section of the rotating shaft 130). When the inflatable shaft 160 is inflated, the raised part on the surface of the inflatable shaft 160 is engaged with the second rotating member 150. The rotating shaft 130 drives the second rotating member 150 to rotate synchronously with the first rotating member 140 through the inflatable shaft 160, that is, the first partition 141 and the second partition 151 rotate synchronously, so that the material in the accommodating chamber 101 moves under the drive of the first partition 141 and the second partition 151, so that the material is discharged from the distributing barrel 110 in a specific volume (the volume of the accommodating chamber 101), thereby achieving the purpose of distributing the material. When the inflatable shaft 160 is deflated, the first rotating member 140 and the second rotating member 150 can move relative to each other to adjust the distance between the first partition 141 and the second partition 151, that is, to adjust the volume of the accommodating chamber 101 to change the volume of the material entering the accommodating chamber 101.

[0049] like Figure 3 and Figure 4As shown, it should be noted that there are three first rotating members 140 and three second rotating members 150. The three first rotating members 140 are equidistantly spaced around the central axis of the distributing barrel 110 and move synchronously. The three second rotating members 150 are equidistantly spaced around the central axis of the distributing barrel 110 and move synchronously. The first rotating members 140 and the second rotating members 150 correspond to each other one by one. The first rotating member 140 also includes a first baffle 142, and the second rotating member 150 also includes a second baffle 152. The first baffle 141 and the first baffle 142 are bent, and the second baffle 151 and the second baffle 152 are bent. The first baffle 142 and the second baffle 152 are both fan-shaped structures, and the centers of the first baffle 142 and the second baffle 152 coincide with the central axis of the distributing barrel 110. Each first baffle 142 is overlapped with its corresponding second baffle 152, and the side of the first baffle 142 away from the first partition 141 is slidably connected to the side of the second baffle 152 away from the second partition 151. When the first rotating member 140 and the second rotating member 50 move relative to each other, the overlapping area between the first baffle 142 and its corresponding second baffle 152 can be changed. For ease of understanding, as shown in FIG. Figure 4 As shown, a receiving chamber 153 is formed between the second partition plate 151 and the second baffle plate 152. When the first rotating member 140 approaches the second rotating member 150, which is arranged to overlap with it, the first rotating member 140 can be accommodated in the receiving chamber 153, the overlapping area of ​​the first baffle plate 142 and the second baffle plate 152 increases, and the volume of the receiving chamber 101 increases. Conversely, when the first rotating member 140 moves away from the second rotating member 150, which overlaps with it, the overlapping area of ​​the first baffle plate 142 and the second baffle plate 152 decreases, and the volume of the receiving chamber 101 decreases. Through the above arrangement, three receiving chambers 101 with the same volume and capable of synchronously adjusting the volume can be formed in the distributing barrel 110, thereby improving the distributing efficiency. In addition, a cylindrical structure may be provided at the center of the material distribution barrel 110 for accommodating structures such as the rotating shaft 130 and the inflatable shaft 160. The first rotating member 140 and the second rotating member 150 may be connected to the cylindrical structure. The first partition 141, the second partition 151, the inner sidewall of the material distribution barrel 110, and the outer sidewall of the cylindrical structure together form the accommodating chamber 101. The above configuration is a feasible embodiment and is provided only to facilitate understanding of the technical solution of the present application and does not specifically limit the technical solution.

[0050] When the material dispensing mechanism 100 is in use, the inflatable shaft 160 is deflated, and the relative distance between the first rotating member 140 and the second rotating member 50 is adjusted according to the desired material volume, thereby adjusting the volume of the accommodating chamber 101 to the desired volume. After the volume of the accommodating chamber 101 is adjusted, the inflatable shaft 160 is inflated, causing the first rotating member 140 and the second rotating member 150 to move synchronously. At this time, the volume of the accommodating chamber 101 remains unchanged, and the rotating shaft 130 drives the first rotating member 140 and the second rotating member 150 to rotate synchronously in the dispensing barrel 110 around the central axis of the dispensing barrel 110 in a specified direction. The material distribution operation is as follows: when the position of one of the accommodating chambers 101 corresponds to the collecting hopper 120, the rotating shaft 130 stops rotating, and the material in the collecting hopper 120 falls into the accommodating chamber 101. When the accommodating chamber 101 is full, the rotating shaft 130 starts rotating, and the first partition 141 and the second partition 151 drive the material to move, and the other accommodating chamber 101 corresponds to the collecting hopper 120 to load the material. The material in the accommodating chamber 101 is moved out of the distributing barrel 110 before the accommodating chamber 101 corresponds to the collecting hopper 120 again, to ensure that the accommodating chamber 101 can continue to be loaded with material when it corresponds to the collecting hopper 120 again. Repeat the above-mentioned material distribution operation to achieve automatic material distribution.

[0051] Through the above-mentioned setting, the beneficial effect of the material dividing mechanism 100 is that the volume of the accommodating chamber 101 can be adjusted by adjusting the relative positions of the first rotating member 140 and the second rotating member 150, thereby dividing the material into multiple portions according to volume, without the need to manually adjust the volume of the accommodating chamber 101, saving time and effort and effectively improving production efficiency.

[0052] Furthermore, based on the above structure, in some embodiments, an adjustment mechanism is provided at the overlapping portion of the first rotating member 140 and the second rotating member 150, and the relative position between the first rotating member 140 and the second rotating member 150 is adjusted by the adjustment mechanism. For example, the adjustment mechanism may employ a rack and pinion structure, wherein the overlapping portion of the first rotating member 140 and the second rotating member 150 are each provided with a rack, a gear is disposed between the two racks, and the gears mesh with the two racks, respectively. The two racks can move toward or away from each other depending on the direction of the gears, thereby adjusting the relative position of the first rotating member 140 and the second rotating member 150, thereby adjusting the volume of the accommodating chamber 101.

[0053] In some embodiments, the dispensing mechanism 100 further includes a driving member 170, a driving rack 111 and a driving gear 180, the driving rack 111 is connected to the dispensing barrel 110, the driving member 170 is arranged on one side of the dispensing barrel 110, the driving gear 180 is connected to the driving member 170, and is used to engage the transmission driving rack 111 to move under the drive of the driving member 170 to drive the dispensing barrel 110 to rotate; the second rotating member 150 is connected to the inner side wall of the dispensing barrel 110, and moves with the side wall of the dispensing barrel 110.

[0054] like Figure 2 and Figure 3 As shown, preferably, the side wall of the distributing barrel 110 and the upper and lower bottom walls of the distributing barrel 110 are separately provided, the driving rack 111 is provided along the outer side wall of the distributing barrel 110, the driving gear 180 can be provided as a single one or multiple ones, and the driving gear 180 is provided on the outer periphery of the distributing barrel 110 and meshes with the driving rack 111. When the driving member 170 drives the driving gear 180 to rotate, the driving gear 180 drives the side wall of the distributing barrel 110 to rotate relative to the bottom wall of the distributing barrel 110, thereby enabling the second rotating member 150 to move relative to the first rotating member 140 when the air shaft 160 is deflated, so as to adjust the relative position of the first rotating member 140 and the second rotating member 150. It should be noted that the driving member 170 can be a device such as a motor.

[0055] For easier understanding, see Figure 2 and Figure 3 The operating steps of the above structure are as follows: when the volume of the accommodating chamber 101 needs to be adjusted, the rotating shaft 130 and the first rotating member 140 remain stationary, and the inflatable shaft 160 is deflated. The driving member 170 drives the driving gear 180 to rotate, and the driving member 170 drives the driving gear 180 to rotate, thereby driving the side wall of the distributing barrel 110 and the second rotating member 150 to move relative to the first rotating member 140. The direction and distance of the relative movement of the first rotating member 140 and the second rotating member 150 can be adjusted by controlling the direction and number of rotations of the driving gear 180, thereby adjusting the volume of the accommodating chamber 101. When the volume of the accommodating chamber 101 is adjusted to a predetermined value, the inflatable shaft 160 is inflated, and the first rotating member 140 and the second rotating member 150 can be driven to move synchronously through the rotating shaft 130 and the inflatable shaft 160 to perform the distributing operation.

[0056] Through the above-mentioned arrangement, the relative positions of the first rotating member 140 and the second rotating member 150 can be automatically adjusted by the driving member 170 and the driving gear 180, thereby adjusting the volume of the accommodating chamber 101 without manual operation, saving time and effort, and effectively improving production efficiency. In addition, the adjustment accuracy of the relative positions of the first rotating member 140 and the second rotating member 150 is higher.

[0057] In some embodiments, the material dispensing mechanism 100 further includes a telescopic mechanism, and the driving member 170 is connected to the telescopic mechanism so that the driving member 170 moves along the length direction of the telescopic mechanism.

[0058] In some embodiments, the material dispensing mechanism 100 further includes a telescopic mechanism (not shown in the figure), which is connected to the driving gear 180 and is used to drive the driving gear 180 to move relative to the driving rack 111, so that the driving gear 180 is engaged with or separated from the driving rack 111.

[0059] The telescopic mechanism is a telescopic rod or a telescopic cylinder, and the telescopic mechanism can be directly or indirectly connected to the driving gear 180. Figure 3 As shown, preferably, the telescopic mechanism is arranged vertically, and the upper end of the telescopic mechanism is connected to the driving member 170. When the telescopic mechanism is in the retracted state, the driving gear 180 is engaged with the driving rack 111; when the telescopic rod is extended, the driving member 170 and the driving gear 180 move upward, so that the driving gear 180 and the driving rack 111 are disengaged. When the telescopic mechanism is shortened, the driving gear 180 approaches the driving rack 111 and engages with the driving rack 111. Through the above-mentioned setting, it is possible to control whether the driving gear 180 is engaged with the driving rack 111. The driving gear 180 moves away from the driving rack 111, so that the driving gear 180 and the driving rack 111 are disengaged. At this time, the driving gear 180 cannot drive the second rotating member 150 to move, so as to ensure that the first rotating member 140 and the second rotating member 150 cannot drive the driving gear 180 and the driving member 170 to rotate when they move synchronously. This can prevent the first rotating member 140 and the second rotating member 150 from being resisted by the driving member 170 when they move synchronously, and avoid damage to the driving member 170 while realizing the above-mentioned adjustment of the accommodating chamber 101.

[0060] In addition, if Figure 2 and Figure 3 As shown, the dispensing mechanism 100 further includes a discharge assembly 102, which is mounted on the outer wall of the dispensing barrel 110 and corresponds to the position where the material is discharged from the dispensing barrel 110. For example, in some embodiments, the opening for discharging the material from the dispensing barrel 110 is opened on the side wall of the lower bottom surface of the dispensing barrel 110, and the discharge assembly 102 is mounted on the side wall of the upper bottom surface of the dispensing barrel 110. The discharge assembly 102 includes a spring and a discharge plate, the middle portion of the discharge plate is rotatably connected to the outer wall of the dispensing barrel 110, one end of the spring is connected to the outer wall of the dispensing barrel 110, and the other end is connected to one end of the discharge plate. It should be noted here that when the material falls into the accommodating chamber 101, the material will accumulate due to the action of gravity, thereby making the material in close contact. When the accommodating chamber 101 corresponds to the opening of the material discharge distributor 110, the material may not be able to fall from the opening under the action of gravity and be discharged from the distributor 110 due to close contact. Through the above arrangement, the other end of the discharge plate applies pressure to the material in the accommodating chamber 101 under the action of the spring, which can make the material be discharged from the distributor 110 through the opening, thereby ensuring that the material can be discharged from the distributor 110 normally.

[0061] See Figure 1 、 Figure 2 、 Figure 5 and Figure 7On the other hand, an automatic packaging machine is provided, which includes the above-mentioned material distribution mechanism 100; and a frame 200, an ice crushing mechanism 300, a film rolling mechanism 400, a transmission mechanism 500, a bag making mechanism 600, a packaging mechanism 700 and a water spraying assembly 800. Among them, the material distribution mechanism 100 is connected to the frame 200; the ice crushing mechanism 300 is connected to the frame 200 and is used to process the materials processed by the material distribution mechanism 100, and the ice crushing mechanism 300 is provided with a discharge port 310; the film rolling mechanism 400 is connected to the frame 200 and is used to provide a film structure; the transmission mechanism 500 is connected to the frame 200, and the film rolling mechanism 40 ... The membrane mechanism 400 is arranged at one end of the transmission mechanism 500, and the transmission mechanism 500 is used to transport the membrane structure along the transmission direction. The middle part of the transmission mechanism 500 is arranged corresponding to the discharge port 310; the bag making mechanism 600 and the packaging mechanism 700 are both arranged corresponding to the transmission mechanism 500, and the bag making mechanism 600 is arranged between the film rolling mechanism 400 and the discharge port 310, and is used to process the membrane structure into a bag-like structure. The packaging mechanism 700 is arranged between the discharge port 310 and the other end of the transmission mechanism 500, and is used to seal the bag-like structure; the water spraying assembly 800 is connected to the frame 200, and is used to inject water into the material distribution mechanism 100.

[0062] like Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, preferably, the material distribution mechanism 100 is mounted on the frame 200, and the ice crushing mechanism 300 is mounted below the material distribution mechanism 100. The material processed (distributed) by the material distribution mechanism 100 falls into the ice crushing mechanism 300, where it is crushed and discharged to the outside of the ice crushing mechanism 300 through the discharge port 310. The film rolling mechanism 400 is provided on the left side of the frame 200, and the transmission mechanism 500 extends from left to right and is used to move the double-layer film structure from the left side of the frame 200 to the right side of the frame 200. During the movement, the double-layer film structure passes through the bag making mechanism 600, the discharge port 310, and the packaging mechanism 700 in sequence. The material discharged from the discharge port 310 falls into the bag structure. After the bag structure is full, the bag structure moves to the packaging mechanism 700 for packaging. When the materials are bagged, the water spray assembly 800 sprays water toward the material distributing mechanism 100 to flush the materials remaining in the material distributing mechanism 100 and the ice crushing mechanism 300 .

[0063] When the automatic packaging machine is in operation, the material (ice cubes) is first processed by the material sorting mechanism 100. The material processed by the material sorting mechanism 100 falls into the ice crushing mechanism 300 for ice crushing, resulting in smaller ice cubes. The smaller ice cubes processed by the ice crushing mechanism 300 are discharged from the ice crushing mechanism 300 through the discharge port 310. While processing the ice cubes, the conveying mechanism 500 transports the double-sided film structure provided by the film winding mechanism 400 to the bag making mechanism 600. The double-layer film structure is sealed and cut by the bag making mechanism 600 to form a bag-like structure. The conveying mechanism 500 drives the bag-like structure to the discharge port 310. The ice cubes processed by the ice crushing mechanism 300 fall into the bag-like structure through the discharge port 310. When the bag-like structure is full, the conveying mechanism 500 drives the bag-like structure to the packaging mechanism 700, which seals the bag-like structure, thereby completing the packaging of one batch of ice cubes. The above steps are repeated to continuously package ice cubes.

[0064] It should be noted that if Figure 1 、 Figure 7 and Figure 10 As shown, the bag-making mechanism 600 includes a longitudinal sealing assembly 610, and the packaging mechanism 700 includes a transverse sealing assembly. When the double-layer film structure moves to the longitudinal sealing assembly 610, the longitudinal sealing assembly 610 uses a cutter to cut the double-layer film structure vertically and heat-seals the cut using a heating device. It should be noted that since the longitudinal sealing assembly 610 only seals the left and right sides of the double-layer film structure, the double-layer film structure can be pre-sealed on the lower side, or a related device can be installed between the film rolling mechanism 400 and the longitudinal sealing assembly 610 to seal the lower side of the double-layer film structure. Through this operation, the double-layer film structure is processed by the longitudinal sealing assembly 610 to form a bag-like structure with sealed left, right, and lower sides. The transverse sealing assembly 710 can seal the upper side of the bag-like structure, making the bag-like structure completely sealed. The above-mentioned configurations are all prior art and will not be elaborated on here. The above content is only for facilitating understanding of the solution and does not constitute a specific limitation.

[0065] Through the above arrangement, the ice crushing mechanism 300 further cuts the ice cubes that were not completely crushed in the previous process to obtain ice cubes that meet production standards. In addition, the water spray assembly 800 can prevent ice cubes from remaining in the distributing mechanism 100 and the ice crushing mechanism 300, thereby ensuring production quality.

[0066] In addition, the water spraying assembly 800 can also be installed at the collecting hopper 120 of the material distribution mechanism 100 to facilitate spraying water into the collecting hopper 120.

[0067] In some embodiments, the ice crushing mechanism 300 includes a housing 320 , a first crushing blade (not shown in the figure), and a second crushing blade (not shown in the figure). The length of the first crushing blade is greater than that of the second crushing blade.

[0068] like Figure 2 and Figure 5 As shown, preferably, both the first crushing blade and the second crushing blade are disposed within the housing 320. Multiple first crushing blades and multiple second crushing blades are provided, with the multiple first crushing blades forming a first crushing blade group and the multiple second crushing blades forming a second crushing blade group. Activating the first crushing blade group can cut the ice cubes within the housing 320 into smaller crushed ice; activating the second crushing blade group can cut the ice cubes within the housing 320 into larger granular ice. Providing two crushing blades of different sizes allows the ice cubes to be cut using different cutting tools, thereby switching between different processing methods depending on the desired ice type, resulting in the desired granular ice or crushed ice.

[0069] In addition, in some other embodiments, the spacing between the multiple first crushing knives is smaller than the spacing between the multiple second crushing knives. The spacing between the multiple first crushing knives and the spacing between the multiple second crushing knives are set according to the size of the crushed ice and granular ice to be produced. By starting the multiple first crushing knives to produce crushed ice and by starting the multiple second crushing knives to produce granular ice, the technical effect of producing granular ice and crushed ice respectively can also be achieved.

[0070] In some embodiments, the film winding mechanism 400 includes a film winding drum 410, a fiber optic sensor (not shown in the figure) and an alarm assembly (not shown in the figure); the film winding drum 410 is rotatably connected to the frame 200, and the film structure is wound around the outer circumference of the film winding drum 410; the fiber optic sensor and the alarm assembly are both connected to the frame 200, and the fiber optic sensor is electrically connected to the alarm assembly and is used to detect the thickness of the film structure wound around the film winding drum 410.

[0071] like Figure 1 、 Figure 6 and Figure 7 As shown, preferably, one end of the double-layer film structure is wound around the outer circumference of the film roll 410, and the other end is connected to the transmission mechanism 500. The transmission mechanism 500 pulls the other end of the double-layer film structure to withdraw the double-layer film structure from the film roll 410. A fiber optic sensor is mounted on the frame 200 and faces the film roll 410. The fiber optic sensor is capable of detecting the distance between itself and the film roll 410. The distance between the fiber optic sensor and the film roll 410 is preset. When the double-layer film structure is wound around the film roll 410, the distance detected by the fiber optic sensor is less than the distance between itself and the film roll 410, thereby determining that the double-layer film structure is still wound around the film roll 410. When the distance between itself and the film roll 410 is close to the preset distance, an alarm is issued through the alarm component, prompting the user to replace or add the double-layer film structure, so that the film roll mechanism 400 can continuously provide the double-layer film structure, ensuring the continuous operation of the automatic packaging machine.

[0072] In some embodiments, the film rolling mechanism 400 further includes a heat sealing mechanism (not shown in the figures), which is connected to the frame 200 and disposed on a side of the film rolling drum 410 .

[0073] like Figure 1 and Figure 6 As shown, preferably, a heat sealing mechanism is mounted on the frame 200, and two film rolls 410 are provided. When the film roll mechanism 400 is in use, one of the film rolls 410 provides a double-layer film structure. When the double-layer film structure outside the film roll 410 is about to be used up, the end of the double-layer film structure wound on the other film roll 410 is bonded to the end of the double-layer film structure wound on the other film roll 410 by the heat sealing mechanism, allowing the film roll mechanism 400 to operate uninterruptedly. This arrangement avoids downtime for replacement or addition of double-layer film structures and reduces waste of double-layer film structures.

[0074] It should be noted that in some embodiments, a robotic arm can be used to butt joint the end of the double-layer film structure wrapped around the other film roll 410 with the end of the double-layer film structure wrapped around the first film roll 410, facilitating heat-sealing by the heat-sealing mechanism. This method of operation using a robotic arm is conventional technology and will not be elaborated upon. The above method is only one feasible embodiment. It only needs to ensure that the double-layer film structures wrapped around the outer circumferences of the two film rolls 410 are smoothly butted together, and does not specifically limit the technical solution of this application.

[0075] In some embodiments, the transmission mechanism 500 includes at least two conveyor belts 510 , which are arranged in parallel, and the double-layer membrane structure is sandwiched between the conveyor belts 510 ;

[0076] It also includes a bag opening mechanism 900, which is arranged corresponding to the discharge port 310. The bag opening mechanism 900 includes two oppositely arranged guide plates 910. The two guide plates 910 are movably connected to the frame 200 and can move toward or away from each other. The two guide plates 910 are arranged between the two conveyor belts 510, and the two conveyor belts 510 are respectively in contact with the opposite side walls of the two guide plates 910.

[0077] like Figure 7 、 Figure 8 and Figure 9As shown, preferably, two conveyor belts 510 are provided. The two conveyor belts 510 are arranged side by side and extend from the left side of the frame 200 to the right side of the frame 200. The two conveyor belts 510 clamp the double-layer membrane structure to drive the double-layer membrane structure to move. The facing side walls of the two guide plates 910 are in contact with each other, and the contact point of the two guide plates 910 is aligned with the discharge port 310. The bag-like structure contacts the bag opening mechanism 900 under the drive of the conveyor belts 510. The ends of the two guide plates 910 that first contact the bag-like structure are defined as the front ends. The front ends of the two guide plates 910 form a sharp angle at a certain angle.

[0078] In the initial state, the two guide plates 910 are in contact with each other, and one of the left and right sides of the bag-like structure contacts the sharp corner. As the bag-like structure moves, the sharp corner presses into the gap between the double-layer plastic film of the bag-like structure, and the double-layer plastic film continues to move along the outer wall of the guide plate 910. At this time, the double-layer plastic film is separated, and the single-layer plastic film is sandwiched between the outer wall of the guide plate 910 and the conveyor belt 510, forming a Figure 8 The annular structure in the middle of the conveyor belt 510 shown in FIG. is used to open the bag opening. When the bag is completely below the discharge port 310, the guide plates 910 move away from each other, fully opening the bag opening between the guide plates 910 and the conveyor belt 510. Material falls into the bag from the discharge port 310. When the bag is full, the two guide plates 910 move toward each other, narrowing the bag opening. The conveyor belt 510 drives the bag forward, and the two conveyor belts 510 reattach behind the bag opening mechanism 900. The upper portion of the bag containing ice cubes is clamped and sealed by the two conveyor belts 510. Driven by the conveyor belts 510, the bag moves toward the packaging mechanism 700 for sealing.

[0079] Through the above arrangement, the bag-like structure can be opened by the bag opening mechanism 900, so that the material dropped from the discharge port 310 can smoothly enter the bag-like structure. The operation is simple and convenient, and the production efficiency of material packaging is effectively improved.

[0080] Further, such as Figure 7 、 Figure 8 and Figure 9 As shown, the transmission mechanism 500 further includes a conveyor wheel 520, which is provided on opposite sides of the two conveyor belts 510. The conveyor belts 510 are in contact with the conveyor wheel 520, and the conveyor belts 510 are driven by the conveyor wheel 520. The bag opening mechanism 900 further includes a driving cylinder 920, which is mounted on the frame 200. Two driving cylinders 920 are provided corresponding to the guide plates 910. The guide plates 910 are connected to the driving cylinders 920 in a one-to-one relationship. The driving cylinders 920 drive the two guide plates 910 to move toward or away from each other.

[0081] It should be noted that a notch is provided on the upper portion of the bag structure near the bag opening mechanism 900 to allow the sharp corner to penetrate between the double-layer plastic film. The conveyor belts 510 can be provided in pairs, or in an even number such as four or six. The conveyor belts 510 are arranged in pairs, ensuring that they can move the double-layer film structure in sequence along the conveying direction.

[0082] In some embodiments, the automatic packaging machine further includes a shaking mechanism 210 , which is connected to the frame 200 and is arranged corresponding to the bag opening mechanism 900 . The shaking mechanism 210 is used to vibrate the bag-like structure located at the bag opening mechanism 900 .

[0083] like Figure 1 、 Figure 2 and Figure 5 As shown, preferably, the shaking mechanism 210 is located directly below the discharge port 310. When the bag-like structure moves to the discharge port 310, the bag-like structure is located between the discharge port 310 and the shaking mechanism 210. When the material falls into the bag-like structure, the shaking mechanism 210 supports the bottom of the bag-like structure and vibrates during the process of the material falling into the bag-like structure. This makes the material more compact within the bag-like structure and avoids excessive gaps between the materials that prevent the bag-like structure from being completely filled.

[0084] In some embodiments, the automatic packaging machine further includes an air storage assembly 220 fixed to the frame 200 . The air storage assembly 220 is connected to the shaking mechanism 210 and is used to drive the shaking mechanism 210 .

[0085] like Figure 1 As shown, preferably, the shaking mechanism 210 is a pneumatic tray, and the gas storage component 220 is a gas storage tank, which provides gas to the pneumatic tray to drive the pneumatic tray to vibrate.

[0086] In addition, the gas storage tank can also provide gas for other gas-driven mechanisms, such as the ice crushing mechanism 300 , the bag making mechanism 600 , and the packaging mechanism 700 .

[0087] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0088] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
