Description

Technical Field

[0001] The utility model relates to the technical field of protection of plastic products, and more particularly to a winding device for plastic protective films. Background Art

[0002] Plastics refer to plastic (flexible) materials formed by processing with high molecular weight synthetic resins as the main component and adding appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc., or rigid materials formed by curing and crosslinking. Subsequently, it can be sold and used after wrapping a protective film on its surface. The protective film can effectively protect the surface of plastic products from scratches.

[0003] The winding device for plastic protective films is usually used for packaging, protecting and fixing articles or products. In order to prevent the pipe wall of plastic pipes from being worn and soaked by rain during transportation and storage, a protective film is usually wrapped outside the plastic pipes. However, the existing winding devices for plastic pipe protective films are not convenient for fixing plastic pipes of different diameters and models, with low applicability. And when it comes to using protective film rolls of different widths, it is not easy to install. As a result, the protective film cannot well wrap the pipes or is wrapped too densely, wasting materials. For this reason, we propose a winding device for plastic protective films to solve the above problems. Summary of the Utility Model

A plastic pipe 7 is arranged at the end of the fixed disk 42 away from the mounting plate 41. The sliding block 9 and the sliding groove 8 form a sliding connection structure.

[0021] In the embodiment of the present application, when in use, according to the length specification model size of the protective film member 66, by starting the third motor 63, the third motor 63 drives the second forward and reverse lead screw 64 to rotate. The second forward and reverse lead screw 64 drives the two moving blocks 65 to move towards the middle relatively, so as to facilitate the fixation of the protective film member 66. Subsequently, the plastic pipe 7 is inserted into the expanding tensioning component 43. Then, by starting the second motor 431, the second motor 431 drives the first forward and reverse lead screw 432 to rotate. The first forward and reverse lead screw 432 drives the two internally threaded moving blocks 433 to move towards the middle relatively. Through the arrangement of the telescopic limiting rod 440, it is convenient to limit the internally threaded moving blocks 433 to prevent them from rotating. The two internally threaded moving blocks 433 move towards the middle relatively and drive the first connecting rod 435 and the second connecting rod 436 to move upward, thereby driving the tensioning plate 438 to expand and tension outward, so that the tensioning plate 438 drives the anti-slip rubber pad 439 to closely adhere to the inner wall of the plastic pipe 7, so as to facilitate the fixation according to plastic pipes 7 with different diameters, and has strong applicability. Then, by starting the first motor 3, the first motor 3 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the mounting plate 41 to rotate, and then drives the fixed disk 42 to rotate, thereby driving the plastic pipe 7 to rotate. Furthermore, through the telescopic movement of the electric push rod 5, it is convenient to push the sliding block 9 to move left and right along the sliding groove 8, so as to drive the protective film member 66 to move left and right, so as to wind the protective film on the outside of the plastic pipe 7.

The number of tensioning plates 438 is three groups, and they are evenly distributed at equal distances along the center point of the plastic pipe 7. The first connecting rod 435 and the second connecting rod 436 are arranged in a cross shape, and the first connecting rod 435 and the second connecting rod 436 form a rotational connection structure through pivot pins. When in use, by starting the second motor 431, the second motor 431 drives the first forward and reverse lead screw 432 to rotate. The first forward and reverse lead screw 432 drives the two internal thread moving blocks 433 to move relatively towards the middle. Through the setting of the telescopic limit rods 440, it is convenient to limit the internal thread moving blocks 433 and prevent them from rotating. The two internal thread moving blocks 433 moving relatively towards the middle drive the first connecting rod 435 and the second connecting rod 436 to move upward, thereby driving the tensioning plate 438 to expand and tighten outward, so that the tensioning plate 438 drives the anti-slip rubber pad 439 to closely adhere to the inner wall of the plastic pipe 7, thus facilitating the fixation of plastic pipes 7 with different diameters, and having strong applicability.

A protective film member 66 is rotatably connected between the two moving blocks 65. The second forward and reverse lead screw 64 passes through one side of the U-shaped frame 61 and extends into the interior of the moving groove 62. The end of the second forward and reverse lead screw 64 away from the third motor 63 is connected to the U-shaped frame 61 through a bearing. During use, by starting the third motor 63, the third motor 63 drives the second forward and reverse lead screw 64 to rotate. The second forward and reverse lead screw 64 drives the two moving blocks 65 to move relatively towards the middle, thereby facilitating the fixing of the protective film member 66 and facilitating the installation of protective film members 66 of different sizes, specifications and models.

[0024] The working principle of the present utility model: During use, first, according to the length, specification and model size of the protective film member 66, by starting the third motor 63, the third motor 63 drives the second forward and reverse lead screw 64 to rotate. The second forward and reverse lead screw 64 drives the two moving blocks 65 to move relatively towards the middle, thereby facilitating the fixing of the protective film member 66. Subsequently, the plastic pipe 7 is inserted into the expansion and tensioning assembly 43. Then, by starting the second motor 431, the second motor 431 drives the first forward and reverse lead screw 432 to rotate. The first forward and reverse lead screw 432 drives the two internally threaded moving blocks 433 to move relatively towards the middle. Through the arrangement of the telescopic limiting rod 440, it is convenient to limit the internally threaded moving blocks 433 and prevent them from rotating. The two internally threaded moving blocks 433 move relatively towards the middle and drive the first connecting rod 435 and the second connecting rod 436 to move upward, thereby driving the tensioning plate 438 to expand outward, so that the tensioning plate 438 drives the anti-slip rubber pad 439 to closely adhere to the inner wall of the plastic pipe 7, thereby facilitating the fixing of plastic pipes 7 of different diameters and having strong applicability. Then, by starting the first motor 3, the first motor 3 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the mounting plate 41 to rotate, and then drives the fixed disk 42 to rotate, thereby driving the plastic pipe 7 to rotate. Furthermore, through the telescopic movement of the electric push rod 5, it is convenient to push the sliding block 9 to move left and right along the sliding groove 8, thereby facilitating the left and right movement of the protective film member 66, and thus winding the protective film on the outer side of the plastic pipe 7.
