It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1

[0027] See also Figure 1-5In this embodiment, an automatic film feeding device of a heat shrink film packaging machine is provided, comprising: a main body 1, a workbench with trapezoidal baffles on both sides of the top of the main body 1; a feeding assembly, provided on one side of the top of the main body 1, for providing power to transport the heat shrink film; a laminating assembly, provided on the table of the main body 1, for cooperating with the feeding assembly for laminating and assisting in feeding; and a cutting assembly, provided on the top of the main body 1, for cutting and dividing the heat shrink film. During use, the main body 1 serves as the frame of the entire device, supporting the feeding assembly, laminating assembly and cutting assembly. The trapezoidal baffles on the workbench help to position and guide the material, thereby ensuring that the various components work together. The material is fed through the feeding assembly and the laminating assembly, and is continuously cut through the cooperation of the cutting assembly, thereby achieving an effective cutting and conveying effect.

[0028] Furthermore, the feeding assembly includes: a feeding table 101 arranged on one side of the top of the main body 1, a feeding motor 102 is provided inside the feeding table 101; a feeding roller 103 is arranged on one side of the feeding motor 102, and the feeding motor 102 is driven and connected to the feeding roller 103 through a driving shaft. During use, the feeding motor 102 drives the feeding roller 103 to rotate through the driving shaft, thereby driving the heat shrink film to move forward, thereby providing continuous power and ensuring a stable supply of the heat shrink film.

[0029] Furthermore, a plurality of anti-slip pads 104 are provided on the surface of the feed roller 103. The anti-slip pads 104 are arranged in a ring structure, and the plurality of anti-slip pads 104 are equidistantly distributed. The anti-slip pads 104 increase the friction when the feed roller 103 rotates, preventing the heat shrink film from slipping, ensuring the stability of the heat shrink film during the feeding process, and avoiding material waste and machine failure.

[0030] Furthermore, the cutting component includes: a cutting roller 3 rotatably connected to the top of the main body 1; a driving platform 301 provided on one side of the top of the main body 1, a driving motor 302 is provided inside the driving platform 301, and one side of the driving motor 302 is driven and connected to the cutting roller 3 through a driving shaft; a cutting knife 305 is provided on both sides of the cutting roller 3. During use, the driving motor 302 drives the cutting roller 3 to rotate through the driving shaft, and the cutting knife 305 completes the cutting of the heat shrink film during the rotation process, thereby realizing automatic cutting and improving production efficiency and cutting accuracy.

[0031] Furthermore, two mounting plates 303 are provided on the surface of the cutting roller 3, and a matching plate 304 is provided on one side of the cutting knife 305. A plurality of threaded openings 306 are provided on the surface of the matching plate 304, and the matching plate 304 is connected to the mounting plate 303 through the threaded openings 306 and bolts. During use, the threaded openings 306 on the matching plate 304 are utilized to enable it to be quickly installed and connected to the mounting plate 303. At this time, the cutting knife 305 is fixed to the mounting plate 303 by bolts, which is convenient for replacement and maintenance, thereby simplifying the replacement process of the cutting knife 305 and reducing maintenance costs and downtime.

[0032] Furthermore, the edge of the cutting knife 305 is arranged in an arc-shaped structure, and the cutting edge of the cutting knife 305 is tangent to the surface of the bonding tape 202. During use, the cutting knife 305 with an arc-shaped edge is used for cutting. When the cutting knife 305 rotates with the cutting roller 3, its cutting edge moves tangentially along the surface of the bonding tape 202, which ensures a smooth cutting action when cutting the heat shrink film, thereby reducing the tearing and burrs of the material and ensuring the smoothness and neatness of the edge of the heat shrink film.

[0033] Furthermore, a control panel 105 is provided on one side of the main body 1. The control panel 105 is electrically connected to the feeding motor 102 and the driving motor 302 respectively. The electrical connection enables rapid control of the device, thereby improving the ease of use of the device.

[0034] Example 2

[0035] Based on Example 1, the laminating assembly includes: two laminating platforms 2 respectively provided on the top of the main body 1, two laminating rollers 201 provided between the bottoms of the two laminating platforms 2; a pulling roller 204 provided between the tops of the two laminating platforms 2, and a laminating belt 202 is sleeved on the surfaces of the laminating rollers 201 and 204, and the laminating belt 202 is in contact with the feed roller 103;

[0036] During use, as the heat shrink film is transferred from the feed roller 103, it is attached to the laminating belt 202 and guided to the desired position by the laminating roller 201 and the pulling roller 204. The laminating belt 202 ensures the flatness and positioning of the heat shrink film during transfer, ensuring that the heat shrink film is straight and stable before entering the cutting assembly, which helps improve cutting accuracy and product quality.

[0037] Furthermore, a traction cavity 203 is provided on the inner wall at the top of the bonding platform 2, and a traction roller 204 is slidably connected to the traction cavity 203. A traction spring 205 is provided on the inner wall at the bottom of the traction cavity 203, and the top of the traction spring 205 is connected to the traction roller 204. When the heat shrink film passes through the bonding belt 202, the traction roller 204 will float up and down according to the thickness and resistance of the material, and the traction spring 205 plays a buffering role, maintaining a constant pressure of the traction roller 204 on the heat shrink film, thereby improving the adaptability of the equipment to heat shrink films of different thicknesses, ensuring tension control during the bonding process, and avoiding excessive stretching or relaxation of the material.

[0038] Furthermore, a pressure roller 106 is rotatably connected to one side of the top of the main body 1, and the bottom of the pressure roller 106 is in contact with one side of the top of the bonding tape 202. During use, the pressure roller 106 is located above the bonding tape 202. As the heat shrink film passes through the bonding tape 202, the pressure roller 106 applies additional pressure to it to ensure that the heat shrink film is fully bonded to the bonding tape 202. It also helps to remove air from the material and reduce the formation of bubbles.
