[0027] in, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The reference direction coordinate system of the embodiment of the present application is given. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the present application is described with reference to the direction shown.

[0028] The embodiment of the present application provides a paper feeding mechanism, see Figures 1 to 5 The paper feeding mechanism includes a moving part 100 and a paper feeding assembly 200. The moving part 100 is provided with a paper outlet 300. The paper feeding assembly 200 is arranged inside the moving part 100. The paper feeding assembly 200 is used to transport paper to the paper outlet 300. The outer periphery of the moving part 100 forms a support part for transporting the plastic film. When the upper film sheet and the lower film sheet of the plastic film are in an opened state, the paper outlet 300 is located between the upper film sheet and the lower film sheet of the plastic film.

[0029] The paper feeding assembly 200 of the paper feeding mechanism can transport the paper to the paper outlet 300. When the upper film and the lower film of the plastic film are opened, the paper outlet 300 is located between the upper film and the lower film of the plastic film. The paper is inserted between the upper film and the lower film of the plastic film. With the movement of the paper feeding assembly 200, the paper is inserted between the upper film and the lower film of the plastic film. Then, since the moving part 100 continues to move in the paper outlet direction, the supporting part on the periphery of the moving part 100 can support the plastic film and drive the plastic film to move to the next process, that is, the paper feeding mechanism 300 pushes the paper and the plastic film forward together until the plastic film and the paper enter the subsequent plastic sealing area entrance, so as to facilitate the plastic sealing of the paper and the plastic film together. The paper feeding mechanism can improve the plastic sealing efficiency. The paper feeding mechanism is used for plastic sealing to ensure the plastic sealing quality, easy operation and low failure rate.

[0030] The paper feeding assembly 200 includes a first roller 210 and a second roller 220. The first roller 210 is located above the second roller 220. A paper feeding area is formed between the first roller 210 and the second roller 220. The paper feeding area is connected to the paper outlet 300. The paper feeding assembly 200 includes a motor capable of driving the first roller 210 and the second roller 220 to rotate. The first roller 210 and the second roller 220 rotate simultaneously, so that the paper sandwiched between the first roller 210 and the second roller 220 moves to extend out of the paper outlet 300. There is a certain friction between the second roller 220 and the paper. When the first roller 210 and the second roller 220 stop rotating, the paper is positioned, which is convenient for inserting the paper between the upper film and the lower film of the plastic film. In some embodiments, the first roller 210 and the second roller 220 are rubber-coated rollers, which effectively drive the movement of the paper. The rubber-coated rollers are usually made of high-quality rubber or polyurethane materials, have good wear resistance and corrosion resistance, long service life, and smooth surface, easy to clean and maintain, extending the service life and maintaining the quality of the paper.

[0031] The paper feeding mechanism includes a pickup wheel 140, which pulls a sheet of paper apart and enters the paper feeding area of ​​the paper feeding assembly 200. The surface of the pickup wheel is covered with a layer of sticky substance made of rubber or similar material. When working, the pickup wheel is located on the top of the paper to be inserted, and is responsible for separating the paper from the stack and transferring it to between the first roller 210 and the second roller 220. Specifically, when the pickup wheel rotates, its sticky surface will grab the top layer of paper, and as it rotates, it will be pulled away from the stack and transferred to between the first roller 210 and the second roller 220.

[0032] A docking portion 130 is provided on the outer side of the moving component 100 , and the docking portion 130 is used to feed the plastic film and paper into the plastic sealing area. It can be understood that there are multiple docking portions 130 , and the multiple docking portions 130 are not arranged along the length direction of the moving component 100 .

[0033] The docking portion 130 includes a first guide plate 131 and a second guide plate 132 arranged on the outside of the moving component 100. A paper outlet channel connected to the paper outlet 300 is formed between the first guide plate 131 and the second guide plate 132. The paper feeding area, the paper outlet 300 and the paper outlet channel are located in the same horizontal plane to facilitate horizontal transportation of paper.

[0034] The support portion includes a first support wall 110 for supporting the upper film of the plastic film and a second support wall 120 for supporting the lower film of the plastic film.

The paper feeding assembly 200 is located in the space surrounded by the first support wall 110 and the second support wall 120. It can be understood that the moving component 100 can be understood as a shell composed of the first support wall 110 and the second support wall 120. The first support wall 110 and the second support wall 120 respectively support the upper film and the lower film of the plastic film, so that the moving component 100 will not cause the plastic film to fall during the movement, thereby realizing the simultaneous transportation of the plastic film and the paper to the next process.

[0035] The top end of the first support wall 110 is located above the first roller 210, and the bottom end of the first support wall 110 extends in the paper output direction and is connected to the first guide plate 131. The bottom end of the second support wall 120 is located below the second roller 220, and the top end of the second support wall 120 extends in the paper output direction and is connected to the second guide plate 132. The first support wall 110 and the second support wall 120 are both arranged obliquely to match the shape of the plastic film in the open state, so as to better support the plastic film. The first guide plate 131 and the second guide plate 132 are convenient for guiding the paper to extend horizontally, so that the paper is aligned with the middle position of the upper film and the lower film of the plastic film, so that the paper can be accurately inserted into the plastic film.

[0036] A guide component 400 is provided at the end of the moving component 100, and the guide component 400 can control the moving component 100 to move along the paper output direction.
