[0055] like Figures 1-4 As shown, this utility model provides a corner-cutting device 6, which includes a bagged product conveying mechanism 61, two sets of support seats 62, a distance adjustment mechanism 63, two sets of pressing components 64, and four sets of corner-cutting components 65.

[0056] The bagged product conveying mechanism 61 is used to convey the bagged product 8 after it has been covered with a film bag along the X-axis. Two sets of support seats 62 are located on either side of the bagged product conveying mechanism 61. The distance adjustment mechanism 63 controls the two sets of support seats 62 to move synchronously in opposite directions along the Y-axis, thereby adjusting the distance between the two sets of support seats 62, so that this invention can adapt to the corner-cutting operation of bagged products 8 of different sizes. Two sets of pressing components 64 are respectively disposed on the two sets of support seats 62. The pressing component 64 includes a pressure plate 641 and a pressure plate moving mechanism 642 that controls the pressure plate 641 to move along the Y-axis. Four sets of corner-cutting components 65 are disposed on the support seats 62. Each set of support seats 62 has two sets of corner-cutting components 65 facing each other, and at least one set of corner-cutting components 65 can move along the X-axis to further adapt to the corner-cutting operation of bagged products 8 of different sizes. Figure 1 As shown, a set of chamfering components 65 on each set of support seats 62 can move along the X-axis. A first slide rail is provided between the chamfering component 65 and the support seat 62 to realize the sliding of the chamfering component 65. A cylinder or hydraulic cylinder for controlling the movement of the chamfering component 65 can also be provided on the support seat 62. The chamfering components 65 on the two sets of support seats 62 are arranged opposite to each other, wherein the clamping component 64 on the same support seat 62 is located between the two sets of chamfering components 65.

[0057] like Figure 1 , Figure 3As shown, the corner-cutting assembly 65 includes a base 651, a corner-cutting assembly moving mechanism 652, a first cutting mechanism 653, a first moving mechanism 654, a second cutting mechanism 655, a second moving mechanism 656, a pressure film guide post 657, a third moving mechanism 658, and a fourth moving mechanism 659.

[0058] Specifically, the base 651 is slidably mounted on the support 62 along the Y-axis; the corner-cutting assembly moving mechanism 652 is mounted on the support 62 and is used to control the base 651 to move along the Y-axis; the first cutting mechanism 653 is slidably mounted on the base 651 along the X-axis; the first moving mechanism 654 is mounted on the base 651 and is used to control the first cutting mechanism 653 to move along the X-axis; the second cutting mechanism 655 is slidably mounted on the base 651 along the Y-axis; the second moving mechanism 656 is mounted on the base 651 and is used to control the second cutting mechanism 655 to move along the Y-axis; the pressure-film guide post 657 is located between the first cutting mechanism 653 and the second cutting mechanism 655 and can move along the X-axis and Y-axis; the third moving mechanism 658 is mounted on the fourth moving mechanism 659 and is used to control the pressure-film guide post 657 to move along the X-axis; the fourth moving mechanism 659 is mounted on the base 651 and is used to control the pressure-film guide post 657 and the third moving mechanism 658 to move along the Y-axis. The second cutting mechanism 655 is located on the side closer to the clamping assembly 64 relative to the first cutting mechanism 653.

[0059] The working principle of this corner-cutting device is as follows: First, all four sets of corner-cutting components 65 move along the Y-axis to a side away from the bagged product conveying mechanism 61, so that the bagged product conveying mechanism 61 can convey the bagged product 8 with the film covering to the four sets of corner-cutting components 65, avoiding affecting the conveying of the bagged product 8; when the bagged product conveying mechanism 61 conveys the bagged product 8 to the four sets of corner-cutting components 65, at this time, the four sets of corner-cutting components 65 are respectively located at the four vertical edges of the bagged product 8 along the Z-axis, and the first cutting mechanism 653 and the second cutting mechanism 655 of each set of corner-cutting components 65 are respectively located at the two vertical plane positions adjacent to the vertical edge; then, all four sets of corner-cutting components 65 move along the Y-axis to a suitable position (the edge of the first cutting mechanism 653) closer to the bagged product 8. The pressure plate 641 is flush with or slightly beyond the vertical edge of the product 8. Then, the pressure plate moving mechanism 642 controls the pressure plate 641 to move towards the bagged product 8 to press and fix the bagged product 8. The first moving mechanism 654 controls the first cutting mechanism 653 to move towards the bagged product 8 to press and tighten the bagged product 8. The fourth moving mechanism 659 controls the film-pressing guide post 657 to move towards the bagged product 8 to a position that touches or approaches the bagged product 8. The third moving mechanism 658 controls the film-pressing guide post 657 to move towards the first cutting mechanism 653 to move excess corner film on the bagged product 8 to the inside of the first cutting mechanism 653. The second moving mechanism 656 controls the second cutting mechanism 655 to move towards the bagged product 8, engaging with the first cutting mechanism 653 to remove excess corner film. This corner-cutting device removes excess corner film from the bagged product 8, resulting in a neat and simple film after heat-shrink sealing of the bagged product 8.

[0060] like Figure 1 , Figure 2 As shown, the distance adjustment mechanism 63 includes a distance adjustment motor 631, a bidirectional lead screw 632 connected to the distance adjustment motor 631, and four support ears 633. Two sets of support seats 62 are located at both ends of the bidirectional lead screw 632 and are equipped with nuts that threadedly engage with the bidirectional lead screw 632. Two bushings 634 are spaced apart at the bottom of each set of support seats 62. Guide shafts 635, which are slidably connected to the four bushings 634, are respectively provided on the four support ears 633. When the distance adjustment motor 631 starts, it drives the bidirectional lead screw 632 to rotate. Since the support seats 62 are threadedly engaged with the bidirectional lead screw 632 through the nuts, the rotation of the bidirectional lead screw 632 causes the two sets of support seats 62 to move in opposite directions along the axial direction of the bidirectional lead screw 632. The sliding connection between the guide shafts 635 and the bushings 634 ensures the stability and straightness of the support seats 62 during movement.

[0061] In one embodiment, two sets of supporting mechanisms 66 are arranged opposite each other on both sides of the bagged product conveying mechanism 61. Both sets of supporting mechanisms 66 are located at the conveying end of the bagged product conveying mechanism 61. Each supporting mechanism 66 includes a supporting plate 661 and a supporting plate lifting mechanism 662 that controls the lifting and lowering of the supporting plate 661. Specifically, the supporting plate lifting mechanism 662 can be a cylinder or a hydraulic cylinder. The piston rod of the cylinder or hydraulic cylinder is connected to the supporting plate 661, and the lifting and lowering of the supporting plate 661 is achieved under the action of the cylinder or hydraulic cylinder. The supporting plates 661 on both sides of the bagged product conveying mechanism 61 are used together to receive the bagged product 8 conveyed from the previous process. Under the action of the supporting plate lifting mechanism 662, the supporting plates 661 are lifted and lowered to place the bagged product 8 on the bagged product conveying mechanism 61.

[0062] In one embodiment, the bagged product conveying mechanism 61 includes a first belt conveyor assembly and a second belt conveyor assembly arranged at intervals and in parallel. Specifically, both the first belt conveyor assembly and the second belt conveyor assembly include a conveying motor 611, a driving wheel 612, a first driven wheel 613, a second driven wheel 614, a tensioning wheel 615, and a belt 616.

The first driven wheel 613 and the second driven wheel 614 are located at the beginning and end of the conveying process, respectively, and the driving wheel 612, the first driven wheel 613, and the second driven wheel 614 are connected by the belt 616.

[0063] In one embodiment, the first cutting mechanism 653 includes a limiting seat 6531 and a blade 6532 disposed on the limiting seat 6531; the second cutting mechanism 655 includes a cutting blade 6551 and a heat insulation plate 6552. A heating element 6553 is disposed inside the cutting blade 6551, and the heating element 6553 is connected to a temperature controller. The heat insulation plate 6552 is connected to a second moving mechanism 656. The heating element 6553 inside the cutting blade 6551 facilitates easier cutting of the film.

[0064] In one embodiment, the cutter 6551 has an inwardly recessed arc-shaped surface 6551a on the side near the pressing component 64, which provides space for the bagged product 8.

[0065] In one embodiment, multiple arc-shaped guide strips 6554 are provided at the concave arc-shaped surface 6551a of the cutter 6551, which can press the film on the bagged product 8 during the movement of the cutter 6551 to better guide the cutting of the corner film.

[0066] like Figures 5-6As shown, this utility model also provides a corner-cutting packaging machine, including an unwinding device 1, a bag-making device 2, a bag-transferring device 3, a product pushing device 4, a sealing device 5, and a corner-cutting device 6. The corner-cutting packaging machine may also include a housing 7, in which all the above-mentioned devices are disposed.

[0067] The unwinding device 1 is used to place the film roll 8, and the film of the film roll 8 is a folded double-layer film 81.

[0068] In one embodiment, such as Figure 7 As shown, the unwinding device 1 includes a motor 11 and a plurality of rotatably arranged rotating rollers 12. The film roll 8 is placed on the first rotating roller 12. The motor 11 is connected to the rotating roller 12 on which the film roll 8 is placed, so that the film roll 8 can rotate. The double-layer film 81 passes around the plurality of rotating rollers 12 in sequence to tighten the double-layer film 81. Preferably, a pressure roller 13 is also provided on one side of one of the rotating rollers 12 to press the double-layer film 81.

[0069] The bag-making device 2 is used to make the double-layer film 81 into a film bag with only one side open.

[0071] In one embodiment, the clamp moving mechanism 24 includes a support frame 241, a conveyor belt 242, and a second slide rail 243. The support frame 241 is fixedly connected to the conveyor belt 242 and slidably connected to the second slide rail 243 to achieve reciprocating movement of the support frame 241. The support hook 22 is disposed on the support frame 241 and located on the opening side of the film bag, moving together with the support frame 241 to open the opening side of the film bag. The support hook 22 can be controlled by a cylinder to penetrate or move out between the upper and lower layers of the double-layer film 81. Preferably, two pneumatic clamps 23 are provided and movably spaced on the support frame 241 to accommodate the traction of double-layer films 81 of different widths.

[0073] The bag transfer device 3 is used to open the film bag and transfer the film bag to the product bag entry position. The product bag entry position is located at the input end of the bagging product conveying mechanism of the four corner cutting device 6, which is also the corresponding position of the sealing device 5.

[0074] In one embodiment, such as Figure 10 , Figure 12 As shown, the bag-moving device 3 includes an upper support 31, a lower support 32, a support lifting mechanism 33 for controlling the lifting of the upper support 31, and a bag-moving mechanism 34 for controlling the movement of the support lifting mechanism 33. The lower support 32 is fixedly installed at the bottom end of the support lifting mechanism 33. Two sets of bag-supporting assemblies 35 are movably installed on both the upper support 31 and the lower support 32. The bag-supporting assembly 35 includes a fixing member 351 movably connected to the upper support 31 / lower support 32, a support plate 352, a clamping plate 353, and a clamping plate cylinder 354 installed on the fixing member 351. The support plate 352 is located inside the clamping plate 353, and the clamping plate cylinder 354 controls the clamping plate 353 to move up and down.

[0075] In this embodiment, the support lifting mechanism 33 that controls the lifting and lowering of the upper support 31 can be a Z-axis linear module. The upper support 31 is connected to the sliding seat of the Z-axis linear module. The bag-moving mechanism 34 that controls the movement of the support lifting mechanism 33 can be a Y-axis linear module. The support lifting mechanism 33 (i.e., the Z-axis linear module) is connected to the sliding seat of the Y-axis linear module. The bag-supporting components 35 on the upper support 31 and the lower support 32 are paired to better open the film bag. The upper support 31 moves up and down along the Z-axis and the bag-supporting components 35 are movably arranged on the upper support 31 and the lower support 32, which facilitates the adjustment of the position of the bag-supporting components 35 to adapt to the opening operation of film bags of different sizes. When the bag-moving operation is performed, the four bag-supporting components 35 are located at the four corners of the film bag, and the support plate 352 is located inside the film bag, while the clamping plate 353 is located outside the film bag. Under the action of the clamping plate cylinder 354, the clamping plate 353 moves towards the support plate 352 to clamp the film, thereby enabling bag moving.

[0076] The product pushing device 4 is located on one side of the product bag entry position and is used to push the product into the film bag.

[0077] In one embodiment, such as Figure 11 , Figure 13As shown, the product pushing device 4 includes a product conveying mechanism 41 for conveying products, a plurality of push plates 42 for pushing products, a push plate lifting mechanism 43 for controlling the lifting and lowering of the push plates 42, and a push plate moving mechanism 44 for controlling the movement of the push plate lifting mechanism 43. Specifically, the structure of the product conveying mechanism 41 is the same as that of the bagged product conveying mechanism 61; the plurality of push plates 42 can be slidably arranged on the third slide rail 45 to facilitate adjustment of the position of the push plates 42 to adapt to the pushing of products of different sizes; the push plate lifting mechanism 43 can be a Z-axis linear module, the push plate moving mechanism 44 can be an X-axis linear module, and the push plate lifting mechanism 43 is connected to the sliding seat of the X-axis linear module.

[0078] The sealing device 5 is used to seal the open side of the film bag containing the product. For example... Figure 8 , Figure 11 As shown, the structure of the sealing device 5 can be the same as that of the heat-cutting mechanism 25.

[0079] The corner-cutting device 6 is used to cut off the film at the four corners of the bagged product 8.

[0080] The working process of this utility model four-corner cutting packaging machine is as follows: The film roll 8 of the double-layer film 81 is placed on the unwinding device 1. Initially, the upper and lower layers of the double-layer film 81 can be manually placed on the upper and lower sides of the separator plate 21, respectively. Then, the front end of the double-layer film 81 is pulled to the position of the heat-cutting mechanism 25, so that the heat-cutting mechanism 25 can heat-cut and seal the front end. After that, the entire process can be automated. The support hook 22 is controlled by a cylinder to extend between the upper and lower layers of the double-layer film 81, and the pneumatic clamp 23 clamps the double-layer film. The film 81 is pulled and moved along one side that has been heat-sealed. When the other side that needs to be sealed moves to the position of the heat-sealing mechanism 25, it stops to facilitate heat-sealing the other side. The four sets of bag-supporting components 35 of the bag-transferring device 3 clamp the four corners of the film bag and move them to the product entry position. After the product pushing device 4 pushes the product into the film bag, the sealing device 5 seals the open side of the film bag. Then the bagged product conveying mechanism 61 conveys the bagged product 8 to the corner-cutting component 65 to cut off the excess corners of the film bag.

[0081] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
