The output end of the fifth motor 420 drives the fourth lead screw 422 to rotate, and in conjunction with the fourth guide bar 423, the push plate 429 on the third movable plate 424 can push the product out.

[0033] Reference Figure 1 As shown, the feeding mechanism 3 includes a second motor 301, which is located at the bottom front end of the frame 1.

A first telescopic cylinder 309 is provided at the top left side of the first mounting frame 304. A pusher 310 is provided at the telescopic end of the first telescopic cylinder 309.

[0034] In this scheme, by setting up a feeding mechanism 3, the first lead screw 302 driven by the output end of the second motor 301 rotates, and the second lead screw 308 driven by the output end of the third motor 306 rotates, so that the material can be conveyed into the frame 1. The pusher 310 controlled by the first telescopic cylinder 309 can push the material to the designated position.

The sorting mechanism 6 includes a third mounting frame 601, which has two sets. One set of the third mounting frame 601 is located inside the top of the second mounting frame 501. Three sets of guide plates 602 are mounted on the bottom of the third mounting frame 601, with two sets of guide plates 602 fitting against the inner side of the third mounting frame 601. Two sets of fourth telescopic cylinders 604 are mounted on the top of one set of the third mounting frame 601. Each set of guide plates 602 has a groove 603 at its top, and a movable door 605 is slidably installed inside each groove 603. The telescopic ends of both sets of fourth telescopic cylinders 604 are also equipped with movable doors 605. A sixth mounting plate 606 is provided at the top of a set of guide plates 602. Two sets of sixth motors 607 are provided at the top of the sixth mounting plate 606. A first bevel gear 608 is provided at the output end of the sixth motor 607. A first guide plate 610 is rotatably mounted on the bottom end of the sixth mounting plate 606 through two sets of rotating shafts. A second bevel gear 609 is provided at the top of each set of rotating shafts. The first bevel gear 608 meshes with the second bevel gear 609. A seventh mounting plate 611 is provided on the left side of another set of third mounting brackets 601. A fifth telescopic cylinder 612 is provided at the top of the seventh mounting plate 611. A drive rack 613 is provided at the telescopic end of the fifth telescopic cylinder 612.

The partially driven gear 614 meshes with the drive rack 613.

[0036] In this solution, the feeding mechanism 5 and the sorting mechanism 6 work together, with the conveyor belt 502 transporting the packaged products to the sorting area. The guide plate 602, the movable door 605, and the first guide plate 610 driven by the sixth motor 607 in the sorting mechanism 6 can accurately classify the products according to different sorting requirements. At the same time, the fifth telescopic cylinder 612 and the active rack 613 on another set of third mounting brackets 601, in conjunction with the partially driven gear 614, realize the flexible rotation of the second guide plate 615, further enhancing the diversity and accuracy of sorting.

[0037] Reference Figure 1-2As shown, the placement mechanism 2 includes a first mounting plate 201, which is located at the top right side of the frame 1. Two sets of first rotating rollers 202 are rotatably mounted on the rear side of the first mounting plate 201. A fixed rod 208 is provided at the top of the frame 1. Two sets of second rotating rollers 203 are rotatably mounted on the inner side of the fixed rod 208. Two sets of adjusting rollers 204 are also rotatably mounted on the inner side of the fixed rod 208. One end of each set of adjusting rollers 204 is connected to the synchronous belt 207 via a synchronous pulley 205. The output end of a first motor 206 is provided on the front side of each set of synchronous pulleys 205.

[0038] In this solution, the first rotating roller 202 on the first mounting plate 201 cooperates with the second rotating roller 203 and the adjusting roller 204 on the fixed rod 208 to provide a stable placement platform for the packaging film. The first motor 206 achieves synchronous rotation of the adjusting roller 204 through the transmission of the synchronous pulley 205 and the synchronous belt 207, ensuring the smooth progress of packaging.

[0039] The working principle of this utility model is as follows: First, two sets of heat shrink film are placed on two sets of first rotating rollers 202 on the first mounting plate 201. At the same time, the output end of the first motor 206 drives one set of synchronous pulleys 205 to rotate, and in conjunction with the transmission of the synchronous belt 207, drives the adjusting roller 204 to rotate synchronously, thereby ensuring that the heat shrink film can be transported forward smoothly and continuously. Second, the feeding mechanism 3 starts to work. The output end of the second motor 301 drives the first lead screw 302 to rotate, transporting the material from the initial position into the machine frame 1. At the same time, the second lead screw 308 driven by the third motor 306 further adjusts the position of the material so that it is aligned with the pusher 310. The pusher 310, controlled by the first telescopic cylinder 309, pushes the material onto the receiving tray 418, preparing for heat shrink packaging. Third, the packaging mechanism 4 is then started. The output end of the fourth motor 405 drives the third lead screw 406 to rotate in the second mounting frame 404, pushing the second movable plate 408 to slide along the third guide strip 407, thereby causing the heat shrink component 411 to descend. The packaging material is tightly wrapped around the packaging material. Simultaneously, the hot-cutting ring 414, controlled by the first lifting cylinder 413, descends, quickly completing the hot-cutting action to ensure the packaging's airtightness. Then, through the cooperation of the second lifting cylinder 415 and the second telescopic cylinder 417, the receiving tray 418 flexibly rises, falls, and extends, effectively receiving and transferring the packaged product to the receiving box 419. Meanwhile, the fifth motor 420 drives the fourth lead screw 422 to rotate, cooperating with the fourth guide bar 423 to allow the push plate 429 on the third movable plate 424 to... The packaged products are pushed to the unloading mechanism 5. Finally, the conveyor belt 502 transports the packaged products to the sorting area. The guide plate 602, the movable door 605, and the first guide plate 610 driven by the sixth motor 607 in the sorting mechanism 6 accurately classify the products according to the preset sorting requirements. At the same time, the active rack 613 driven by the fifth telescopic cylinder 612 cooperates with the partially driven gear 614 to realize the flexible rotation of the second guide plate 615, further enhancing the diversity and accuracy of sorting.
