Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to Figure 1 、 Figure 2 and Figure 3, an embodiment provided by the present utility model: a plastic packaging film anti-wrinkle compounding machine, including a base 1, both the left and right sides of the top of the base 1 are fixedly connected with baffles 3, the front ends of the adjacent sides of the two baffles 3 are fixedly connected with a first fixing rod 4, a film unwinding reel 5 is rotatably connected to the outer wall of the first fixing rod 4, the upper and lower parts of the front sides of the adjacent sides of the two baffles 3 are fixedly connected with second fixing rods 6, the outer walls of the two second fixing rods 6 are rotatably connected with first rotating cylinders 7, grooves 8 are opened in the middle parts of the adjacent sides of the two baffles 3, the bottom ends of the two grooves 8 are fixedly connected with first telescopic rods 9, the tops of the two first telescopic rods 9 are fixedly connected with moving blocks 10, two third fixing rods 11 are fixedly connected to the adjacent sides of the two moving blocks 10, the outer walls of the two third fixing rods 11 are rotatably connected with second rotating cylinders 12, a fourth fixing rod 13 is fixedly connected to the rear ends of the adjacent sides of the two baffles 3, a third rotating cylinder 14 is rotatably connected to the outer wall of the fourth fixing rod 13, a cross plate 15 is fixedly connected to the top of the rear ends of the adjacent sides of the two baffles 3, second telescopic rods 16 are fixedly connected to both the left and right sides of the bottom of the cross plate 15, the bottom ends of the second telescopic rods 16 are fixedly connected with the same U-shaped frame 17, a heating rotating cylinder 18 is rotatably connected to the bottom of the U-shaped frame 17, and a winding mechanism 2 is arranged at the rear end of the base 1;

[0040] Specifically, place the film on the film unwinding reel 5, and then pass it through the first rotating cylinders 7 located outside the two second fixing rods 6, and at the same time, also pass it through the second rotating cylinders 12 located outside the two third fixing rods 11. The sensor 27 at the bottom of the cross bar 26 will monitor the film in real time. When the film tension is insufficient, the sensor 27 will trigger the operation of the first telescopic rod 9, thereby pushing the moving block 10 to move upward, so that the third fixing rod 11 drives the second rotating cylinder 12 to move upward, adjusting the angular distance between the third fixing rod 11 and the second fixing rod 6, so as to adjust the film tension and reduce the generation of wrinkles. In addition, by turning on the switch 23, the second telescopic rod 16 will drive the U-shaped frame 17 to move downward, so that the heating rotating cylinder 18 moves downward and approaches. The heating rotating cylinder 18 and the third rotating cylinder 14 rotatably connected to the outer wall of the fourth fixing rod 13 act together to press the film. During the pressing process, the heat helps the film to fuse more easily, effectively preventing the formation of wrinkles.

[0041] Refer to Figure 4 and Figure 5, the rewinding mechanism 2 includes a fixed plate 201. The two fixed plates 201 are respectively fixedly connected to the left and right sides of the rear end of the base 1. A motor 202 is fixedly connected to the right side of the right fixed plate 201. The output end of the motor 202 penetrates through the fixed plate 201 and is fixedly connected to a rotating shaft 203. An outer wall of the rotating shaft 203 is fixedly connected to a winding drum 204. A plurality of limiting holes 205 are equidistantly formed at the top of the winding drum 204. Both ends of the winding drum 204 are slidably connected to a limiting plate 206. A prolongation plate 207 is fixedly connected to the far side of each of the two limiting plates 206. A limiting bolt 208 is rotatably connected to the top of each of the two prolongation plates 207. The bottom ends of the two limiting bolts 208 penetrate through the prolongation plate 207;

[0042] Specifically, it is necessary to turn on the switch 23 to drive the rotating shaft 203 to rotate by the motor 202, so that the winding drum 204 rotates accordingly, thereby realizing the winding of the film. By adjusting the positions of the limiting plates 206 at both ends of the winding drum 204, the winding of films with different widths can be adapted. When moving the limiting plate 206, the prolongation plate 207 will move accordingly. At this time, rotate the limiting bolt 208 at the top of the prolongation plate 207 to make it pass through the prolongation plate 207 and enter the corresponding limiting hole 205, so as to fix and limit the prolongation plate 207.

[0043] Refer to Figure 1 , Figure 2 and Figure 5 , rubber pads 20 are fixedly connected to the bottoms of the four corners of the bottom of the base 1. Chute grooves 21 are formed in the middle and rear parts of the adjacent sides of the two baffle plates 3. Slide blocks 22 are fixedly connected to the left and right sides of the U-shaped frame 17. The plurality of slide blocks 22 respectively slide inside the corresponding chute grooves 21. A switch 23 is fixedly connected to the right side of the baffle plate 3. The switch 23 is electrically connected to the motor 202, the first telescopic rod 9 and the second telescopic rod 16;

[0044] Specifically, the support feet 19 and the rubber pads 20 can support the base 1 during operation to keep the base 1 in a stable state. The rubber pads 20 can increase the friction force. The chute grooves 21 and the slide blocks 22 can make the U-shaped frame 17 move up and down more stably between the baffle plates 3. The switch 23 can freely control the operation of the motor 202, the first telescopic rod 9 and the second telescopic rod 16.

[0045] Refer to Figure 1 and Figure 3 , a storage box 24 is fixedly connected to the right side of the baffle plate 3. A rotating cover 25 is rotatably connected to the top of the storage box 24. Cross bars 26 are fixedly connected to the upper middle parts of the adjacent sides of the two baffle plates 3. Sensors 27 are fixedly connected to the bottoms of the two cross bars 26. The bottom ends of the two limiting bolts 208 penetrate through the prolongation plate 207 and are rotatably connected in the limiting holes 205. The sizes of the limiting bolts 208 and the limiting holes 205 are the same;

[0046] Specifically, the storage box 24 can facilitate the staff to temporarily place the tools used during work. The sensor 27 can monitor the tension of the film. When the tension is insufficient, it can control the first telescopic rod 9 to work and adjust the tension. The limit bolt 208 passes through the extension plate 207 and turns into the limit hole 205 to limit the extension plate 207. The consistent size can make the limit bolt 208 more stable and not easy to shake.

[0047] Working principle: When using a plastic-sealed packaging film anti-wrinkle compounding machine, the film needs to be first placed on the unwinding reel 5. At this time, the film passes through the first rotating cylinders 7 on the outer walls of the two second fixing rods 6 and at the same time passes through the second rotating cylinders 12 on the outer walls of the two third fixing rods 11. At this time, the sensor 27 at the bottom of the cross bar 26 monitors the film. When the film tension is insufficient, the sensor 27 activates the first telescopic rod 9 to push the moving block 10 to move upward. At this time, the third fixing rod 11 drives the second rotating cylinder 12 to move upward, so that the angle between the third fixing rod 11 and the second fixing rod 6 changes to change the film tension. By changing the angle between the third fixing rod 11 and the second fixing rod 6, the tension is changed to reduce the generation of wrinkles. At the same time, turn on the switch 23 to make the second telescopic rod 16 work to push the U-shaped frame 17 to move downward, so that the heating rotating cylinder 18 moves downward. At this time, the third rotating cylinder 14 rotatably connected to the outer wall of the fourth fixing rod 13 by the heating rotating cylinder 18 presses the film. At the same time, heat is generated during pressing, making the film easier to press and preventing the generation of wrinkles. And the film can be wound up. At this time, turn on the switch 23 to make the motor 202 work to drive the rotating shaft 203 to rotate, so that the winding reel 204 rotates to wind up the film. At the same time, by moving the position of the limit plates 206 at both ends of the winding reel 204, films of different widths can be wound up. At this time, move the limit plates 206 at both ends of the winding reel 204, so that the extension plate 207 moves accordingly. At the same time, rotate the limit bolt 208 at the top of the extension plate 207, which passes through the extension plate 207 and rotates into the corresponding limit hole 205 to limit and fix the extension plate 207.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
