Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically a packaging device for POF heat shrink film. Background Technology

[0002] POF heat shrink film is a multilayer co-extruded polyolefin heat shrink film. It uses linear low-density polyethylene as the middle layer and copolymer polypropylene as the inner and outer layers. It is processed through special extrusion, die forming and film bubble inflation processes. It has the characteristics of being non-toxic and environmentally friendly, high transparency, high shrinkage rate, good heat sealing performance, toughness, tear resistance and uniform heat shrinkage. POF heat shrink film is widely used in the packaging field. After the POF heat shrink film is completely produced, it is generally rolled up in a roll and then packaged by packaging equipment.

[0003] For example, the authorized patent with announcement number CN217533471U (a POF heat shrink film packaging device) includes an operating table. The upper middle part of the operating table is provided with a packaging sealing component. The packaging sealing component includes a sealing shell and a cutter. There are two sealing shells.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a packaging device for POF heat shrink film, including a device platform 1, a placement rack 2 above the device platform 1, a front pad 3 fixedly installed above the device platform 1 along the front end of the placement rack 2, side pads 4 symmetrically arranged on both sides of the rear end of the front pad 3, a screw box 5 fixedly installed at the front end of the front pad 3, a sealing assembly 10 above the placement rack 2, the sealing assembly 10 including a front pressure plate 1001, side pressure plates 1002 and a screw box 2 1003, the screw box 2 1003 fixedly installed at the front end of the front pressure plate 1001, two side pressure plates 1002 are provided, the two side pressure plates 1002 are symmetrically arranged on both sides of the rear end of the front pressure plate 1001, a front heating sealing strip 11 is fixedly installed on the lower end surface of the front pressure plate 1001, and a side heating sealing strip 12 is fixedly installed on the lower end surface of the side pressure plates 1002.

[0024] By designing a sealing assembly 10 including a front pressure plate 1001, a side pressure plate 1002, and a corresponding screw box 1003, wherein the front pressure plate 1001 and the side pressure plate 1002 are respectively equipped with a front heating sealing strip 11 and a side heating sealing strip 12 on their lower end faces, the position of the side pressure plate 1002 can be adjusted to adapt to the packaging requirements of POF heat shrink film rewinding materials of different widths without replacing the entire packaging sealing component. Furthermore, when packaging POF heat shrink film rewinding materials, by driving the front pressure plate 1001 and the side pressure plate 1002 to move downward and cooperate with the front pad 3 and the side pad 4, the packaging film of the POF heat shrink film rewinding material can be heat-sealed, thereby improving the versatility and practicality of the device.

[0025] Please see Figure 3 Inside the second screw box 1003, a ball screw 15 is rotatably mounted. A drive motor for the ball screw 15 is provided on one side of the second screw box 1003. The threads at both ends of the outer side of the ball screw 15 are arranged in opposite directions. Sliding blocks 16 are symmetrically mounted on both ends of the outer side of the ball screw 15 through ball nuts. A transmission plate 17 is fixedly mounted on one side of each of the two sliding blocks 16. One end of each of the two transmission plates 17 slides through the front pressure plate 1001 and is fixedly connected to the two side pressure plates 1002 respectively. The internal structure of the first screw box 5 is the same as that of the second screw box 1003, and the ball screw in the first screw box 5 is also fixedly connected to the two side pads 4 through the two transmission plates respectively.

[0026] This allows the two side pressure plates 1002 and the two side pads 4 to move synchronously, enabling the sealing assembly 10 to better adapt to POF heat shrink film rewinding materials of different widths, thus increasing its practicality.

[0027] Please see Figure 2 A mounting plate 9 is provided above the sealing assembly 10. The mounting plate 9 is fixedly connected to the front pressure plate 1001. Vertical plates 13 are symmetrically fixedly installed on both sides of the rear end of the mounting plate 9. A stabilizing rod 14 is fixedly installed between the two vertical plates 13. The stabilizing rod 14 slides through the side pressure plate 1002.

[0028] The stabilizing bar 14 enhances the stability of the side pressure plate 1002 during movement, preventing the side pressure plate 1002 from shaking or shifting when adjusting its position, thereby ensuring the reliability of the sealing assembly 10 and improving the sealing quality.

[0029] Please see Figure 1 A top plate 7 is provided above the mounting plate 9. A back plate 6 is fixedly installed at the rear end above the device platform 1. The top plate 7 is fixedly connected to the back plate 6. A hydraulic cylinder 8 is fixedly installed above the top plate 7. The piston rod end of the hydraulic cylinder 8 slides through the top plate 7 and is fixedly connected to the mounting plate 9.

[0030] The hydraulic cylinder 8 is designed to drive the sealing assembly 10 to move up and down, thereby facilitating the sealing operation of the packaging film.

[0031] Please see Figure 1 and Figure 4 The placement frame 2 includes a plate base 201 and a rotating roller 202. There are two plate bases 201 and two rotating rollers 202. The two rotating rollers 202 are rotatably installed between the front and rear ends of the two plate bases 201. The plate base 201 is fixedly connected to the device platform 1.

[0032] This allows the POF heat shrink film roll to be placed stably on the placement rack, increasing its practicality.

[0033] Working principle: In use, place half of the cut packaging film on the placement rack 2, then place the POF heat shrink film roll to be packaged on the packaging film on the placement rack 2, and then cover the other half of the packaging film on the POF heat shrink film roll, so that the front end and sides of the packaging film are on the front pad 3 and side pad 4 respectively. Then, the hydraulic cylinder 8 drives the sealing assembly 10 to move down, and through the cooperation of the front pressure plate 1001 and the side pressure plate 1002 with the front pad 3 and the side pad 4, the sealing assembly 10 is closed. Under the action of the heating sealing strip 11 and the side heating sealing strip 12, the edge of the packaging film is heat-sealed, realizing the packaging of POF heat shrink film roll material. If it is necessary to package POF heat shrink film of different widths, the ball screw 15 can be driven to rotate, which drives the two sliding blocks 16 to move synchronously. The transmission plate 17 on the sliding block 16 drives the two side pressure plates 1002 to move synchronously to adapt to different width requirements. The stabilizing rod 14 slides through the side pressure plate 1002 to enhance the stability of movement.
