[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] One embodiment of this application provides a side-feed drop-type sealing and cutting machine, such as... Figure 1 As shown, it includes: a frame 1, the frame 1 having a worktable 102; a sealing and cutting mechanism 2 is provided on the frame 1, and a first film feeding mechanism 3 and a second film feeding mechanism 4 are respectively provided on the upper and lower parts of the frame 1; the sealing and cutting mechanism 2 is located between the first film feeding mechanism 3 and the second film feeding mechanism 4; a first pushing mechanism 5 is provided on the worktable 102 of the frame 1, the first pushing mechanism 5 pushes the product to be packaged to the sealing and cutting area, so that the product to be packaged is covered with a film, and then the sealing and cutting mechanism 2 heat-seals and cuts the film to realize the packaging of the product. It should be noted that a film for packaging is provided between the first film feeding mechanism 3 and the second film feeding mechanism 4. The two ends of the film are respectively wound and connected to the first film feeding mechanism 3 and the second film feeding mechanism 4 respectively. The first film feeding mechanism 3 and the second film feeding mechanism 4 enable the wound film to be rotated when pulled by external force. When the first pushing mechanism 5 is working, it pushes the product to the area to be sealed and cut. The film moves together on the frame 1 under the drive of the product, so that the film covers the surface of the product. Then the sealing and cutting mechanism 2 heat seals the film and cuts the film to realize the packaging of the product.

[0024] The frame 1 is provided with a conveying channel 6. There is a preset height between the discharge end of the conveying channel 6 and the worktable 102. This preset height is slightly larger than the length of the small cylindrical product 7. The preset height ensures that the product will not be scattered during the feeding process. The conveying channel 6 is arc-shaped and has a channel for the small cylindrical product 7 to pass through, so as to ensure that the small cylindrical product 7 can reach the worktable 102 of the frame 1 in sequence.

[0025] The side of the frame 1 is provided with a second pushing mechanism 8, which pushes the products conveyed by the conveying channel 6 to the waiting area of ​​the first pushing mechanism 5 in sequence.

[0026] The frame 1 has a conveyor line 10 on its side, which is used to transport products to be packaged. The conveyor line 10 is existing technology and will not be described in detail. The discharge end of the conveyor line 10 is higher than its inlet end, allowing the products to move uphill on the conveyor line 10. The inlet end of the conveyor channel 6 cooperates with the discharge end of the conveyor line 10. Products to be packaged output from the discharge end of the conveyor line 10 enter the workbench 102 through the conveyor channel 6, and are then pushed sequentially to the push area of ​​the first pusher mechanism 5 by the second pusher mechanism 8. The conveyor line 10 creates a height difference between the workbench 102 and the discharge end of the conveyor line 10. The conveyor channel 6 connects the conveyor line 10 and the workbench 102, enabling the packaging of small cylindrical products 7, with ten products packaged together. This type of machine is much smaller than the original model, making it easier to set up. Compared to the old model, the advantage is that the overall equipment size is smaller, and the packaged product size can also be smaller.

[0027] As further explained, in this embodiment, such as Figure 1 As shown, the first film feeding mechanism 3 includes two first rollers 31 rotatably connected to the upper part of the frame 1 and arranged at intervals. Two or more first winding cylinders 32 are rotatably connected to the side of the inner first roller 31. The second film feeding mechanism 4 includes two second rollers 41 rotatably connected to the lower part of the frame 1 and arranged at intervals. Two or more second winding cylinders 42 are rotatably connected to the side of the inner second roller 41. The two ends of the film are respectively wound and located on the first film feeding mechanism 3 and the second film feeding mechanism 4, and are wound with the first winding cylinder 32 and the second winding cylinder 42 respectively, so that the wound film can be easily rotated when pulled by external force. This winding method and structure are existing technologies and will not be described in detail.

[0028] As further explained, in this embodiment, such as Figure 1As shown, the first pushing mechanism 5 includes a first power component 51 connected to the table surface of the frame 1. The first power component 51 is a cylinder, which is existing technology and will not be described in detail. The output end of the first power component 51 is connected to a first push plate 52, which is used to push the product out, so that the product drives the film to move to the other side, thereby achieving film coverage of the product.

[0029] As further explained, in this embodiment, such as Figure 1 As shown, the second pushing mechanism 8 includes a second power component mounted on the frame 1. The second power component is a cylinder, which is existing technology and will not be described in detail here. The output end of the second power component is connected to a second push plate, which is used to push the products conveyed by the conveying channel 6 to the push area of ​​the first pushing mechanism 5 in sequence.

[0030] As further explained, in this embodiment, such as Figure 1 As shown, the discharge end of the conveyor line 10 is provided with a pressing component for product limiting. The pressing component is at a preset distance from the conveying surface of the conveyor line 10 so that the product can pass through. The conveyor line 10 is provided with a limiting component 101, which forms a channel for small cylindrical products 7 to pass through.

[0031] As further explained, in this embodiment, such as Figures 2-3 As shown, the sealing and cutting mechanism 2 is located in front of the film to be packaged; the sealing and cutting mechanism 2 includes a first heat sealing die head 21 and a second heat sealing die head 22 slidably connected to the frame 1. The first heat sealing die head 21 and the second heat sealing die head 22 are both existing technologies, and their structures and working principles are also existing technologies, so they will not be described in detail here; the first heat sealing die head 21 and the second heat sealing die head 22 are arranged opposite to each other, and the first heat sealing die head 21 and the second heat sealing die head 22 together weld the film provided by the first film feeding mechanism 3 and the second film feeding mechanism 4; the first heat sealing die head 21 and the second heat sealing die head 22 are respectively located on the upper and lower sides of the worktable 102; the second heat sealing die head 22 is connected to the output end of the third power component 23 provided on the frame 1. The third power component 23 is a cylinder, which is existing technology, so it will not be described in detail here.

[0032] It also includes a mounting bracket 28 slidably connected to the frame 1, the mounting bracket 28 being connected to the output end of a fourth power component 24 disposed on the frame 1; the fourth power component 24 is a cylinder, which is prior art and will not be described in detail; a cutter 25 is connected to the mounting bracket 28, and the first heat sealing die 21 is connected to the mounting bracket 28 via an elastic member 29, the first heat sealing die 21 having a slot parallel to the length direction of the first heat sealing die 21, the slot being located in the middle of the first heat sealing die 21; the first heat sealing die 21 is connected to the cutter 25 via the slot. In conjunction with the elastic element 29, the end of the first heat-sealing die 21 is higher than the blade of the cutter 25. The second heat-sealing die 22 is provided with a cutting groove 26 that cooperates with the cutter 25. After the first heat-sealing die 21 and the second heat-sealing die 22 weld the film, the cutter 25 continues to move under the action of the fourth power element 24. The first heat-sealing die 21 overcomes the elastic force of the elastic element 29 and makes room. The cutter 25 cooperates with the cutting groove 26 on the second heat-sealing die 22 to cut the welded film, thereby separating the packaged product from the film.

[0033] As a further step, in this embodiment, the side of the first heat sealing die head 21 is provided with a protective plate to prevent other personnel from accidentally touching the sealing and cutting mechanism 2 and causing unnecessary damage.

[0034] As a further example, in this embodiment, such as Figure 2 As shown, the mounting bracket 28 is provided with a limiting rod 210 for limiting the first heat sealing mold head 21.

[0035] As a further example, in this embodiment, such as Figure 1 As shown, it also includes a pressing unit 11, which includes a pressing power component 111 connected to the frame 1 or the worktable 102. The pressing power component 111 is a cylinder, which is existing technology and will not be described in detail. The output end of the pressing power component 111 is connected to a pressing plate 112. The pressing unit 11 presses down on the products pushed out by the second pushing mechanism 8. When the number of products on the worktable 102 reaches a preset number, the first pushing mechanism 5 pushes them out together to the sealing and cutting area. There is a product movement space between the pressing plate 112 and the worktable 102 so that the products can move between the pressing plate 112 and the worktable 102.

[0036] During implementation, the product to be packaged is conveyed to the conveying channel 6 via the conveyor line 10 and enters the worktable 102. The second pushing mechanism 8 pushes the product to be packaged on the worktable 102 sequentially to the pushing area of ​​the first pushing mechanism 5. Then, the first pushing mechanism 5 pushes out the product to be packaged, so that the product to be packaged is covered with a film. After being pushed to a preset distance, the first heat sealing die head 21 and the second heat sealing die head 22 weld the film together. The cutter 25 continues to move under the action of the fourth power member 24. The first heat sealing die head 21 overcomes the elastic force of the elastic member 29 to give way. The cutter 25 cooperates with the cutting groove 26 on the second heat sealing die head 22 to cut the welded film, and the packaging is completed.
