[0002] Shrink film has high puncture resistance, good shrinkage, and a certain shrinkage stress. It is mainly used in the sales and transportation of various products to stabilize, cover, and protect them. Shrink packaging not only makes the product look nice, but also serves to prevent moisture, dust, loosening, theft, and aggregation. Shrink film can be used as the outer packaging of garbage bags, providing good moisture and dust protection. During the production of shrink film, it needs to be sealed and cut using a sealing device.

[0003] For example, announcement number CN214690537U proposes a heat shrink film sealing and cutting device, including a machine body, a sealing and cutting groove in the middle of the top of the machine body, and a sealing and cutting component corresponding to the sealing and cutting groove fixedly on the top of the machine body. The sealing and cutting component includes a fixing frame, a cutting plate, two electric telescopic rods, two limiting rods, a sealing and cutting knife, and two electric heating plates. However, in the process of using this utility model, it directly heat seals the shrink film and does not have the function of flattening the shrink film. Since the surface of the shrink film generally has wrinkles, it affects the processing quality of the shrink film when heat sealing the shrink film used for the outer packaging of garbage bags.

[0004] Therefore, to solve the above problems, a high-efficiency automatic shrink film sealing device for the outer packaging of garbage bags is proposed. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This embodiment of a high-efficiency automatic shrink film sealing device for the outer packaging of garbage bags includes a base 1, a support frame 2 is provided on the upper end surface of the base 1, a cylinder 3 is provided on the inner side of the support frame 2, a fixed plate 4 is slidably provided inside the support frame 2, the output end of the cylinder 3 is fixedly connected to the fixed plate 4, a sealing and cutting knife 5 and two heating plates 20 are provided on the lower end surface of the fixed plate 4, a flattening component is provided on the fixed plate 4, and a feeding component is provided on the base 1.

[0024] In actual use, by placing the shrink film on the base 1 so that the shrink film is below the sealing and cutting knife 5, the cylinder 3 is started to drive the fixed plate 4 to move, and the sealing and cutting knife 5 seals and cuts the shrink film to facilitate transportation. At the same time, the heating plate 20 heats the shrink film during sealing and cutting, so that the shrink film shrinks and seals, thus performing the sealing and cutting process.

[0025] Please see Figure 1-3The flattening assembly includes two fixed frames 6 located on the lower end face of the fixed plate 4. A baffle 12 is provided inside the fixed frame 6. A rotating rod 7 is rotatably provided inside the fixed frame 6. Two connecting rods 8 are provided on the outside of the rotating rod 7. The baffle 12 abuts against the connecting rods 8. The connecting rods 8 are inclined. A mounting frame 9 is provided at one end of the two connecting rods 8. A flattening roller 10 is rotatably provided inside the mounting frame 9. The sealing and cutting knife 5 is located between the two flattening rollers 10.

[0026] In actual use, the baffle 12 can restrict the connecting rod 8, making the connecting rod 8 inclined. When the fixed plate 4 moves downward, the flattening roller 10 first contacts the shrink film on the base 1. By squeezing the flattening roller 10, the flattening roller 10 rotates around the rotating rod 7 through the connecting rod 8, so that the two flattening rollers 10 roll on the surface of the shrink film. The two flattening rollers 10 cooperate to flatten the shrink film.

[0027] Please see Figure 1-2 Two torsion springs 11 are fitted on the outer side of the rotating rod 7. One end of the torsion spring 11 is fixedly connected to the inner side of the fixing frame 6, and the other end of the torsion spring 11 is fixedly connected to the outer side of the connecting rod 8.

[0028] It should be noted that when the connecting rod 8 rotates around the rotating rod 7, the torsion spring 11 deforms. By setting the torsion spring 11, when the flattening roller 10 rotates around the rotating rod 7 via the connecting rod 8, when the cylinder 3 drives the fixed plate 4 to reset and the flattening roller 10 is no longer squeezed, the torsion spring 11 drives the connecting rod 8 to rotate and reset it.

[0029] Please see Figure 1 The feeding assembly includes two support plates 13 located on the upper surface of the base 1. A motor 14 is located on one side of the left support plate 13. A rotating rod 15 is located on the output shaft of the motor 14. Two connecting cylinders 16 are located on the outer side of the rotating rod 15. Movable rods 17 are movably arranged inside the connecting cylinders 16. A feeding plate 18 is located at one end of the two movable rods 17. A spring 19 is located inside the connecting cylinders 16.

[0030] Please see Figure 1 and Figure 4 The connecting cylinder 16 has an internal movable hole that matches the size of the movable rod 17. A rubber pad is provided on the outer side of the feeding plate 18. One end of the spring 19 is fixedly connected to the inner wall of the connecting cylinder 16, and the other end of the spring 19 is fixedly connected to one end of the movable rod 17.

[0031] In actual use, when the feeding plate 18 is rotated by the motor 14, the feeding plate 18 contacts the base 1. The feeding plate 18 slides inside the connecting cylinder 16 through the movable rod 17. The spring 19 ensures that the feeding plate 18 continuously abuts against the base 1. The feeding plate 18 pushes the shrink film after the sealing and cutting process is completed. The rubber pad increases the friction between the feeding plate 18 and the shrink film.

[0032] The working principle of the above embodiments is as follows:

[0033] When sealing shrink film used for the outer packaging of garbage bags, the shrink film is placed on the base 1, positioned below the sealing and cutting blade 5. The cylinder 3 is activated to move the fixing plate 4, and the sealing and cutting blade 5 seals the shrink film for easy transport. Simultaneously, the heating plate 20 heats the shrink film during sealing, causing it to shrink and seal. At the same time, as the fixing plate 4 moves downwards, the flattening roller 10 first contacts the shrink film on the base 1. The flattening roller 10 is squeezed, and it rotates around the rotating rod 7 via the connecting rod 8, causing the two pressure rollers to... The flat roller 10 rolls on the surface of the shrink film, and two flattening rollers 10 work together to flatten the shrink film, reducing wrinkles on its surface during the shrink film sealing process and improving the sealing quality of the shrink film. In addition, after the shrink film is sealed and cut, the motor 14 drives the connecting cylinder 16 outside the rotating rod 15 to rotate, so that the feeding plate 18 rotates with it. The feeding plate 18 pushes the shrink film after sealing and cutting, which facilitates the collection of the processed shrink film, making the processing of shrink film more efficient and convenient for users.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
