Description

Technical Field

[0001] The utility model relates to the technical field of stretch film production, in particular to an anti-wrinkle film pressing device for stretch film production. Background Art

[0002] Stretch film is a plastic film used to wrap and protect goods, also known as wrap film, stretch film or packaging film. It is usually made of plastic materials such as polyethylene or polypropylene, and has excellent stretchability and wear resistance. Therefore, it is often used to wrap goods to protect them from moisture, dust and damage, and to fix and stabilize goods to prevent them from shifting or tipping over during transportation and storage. In the production process of stretch film, in order to facilitate storage and transportation, an anti-wrinkle film pressing device is usually required for winding.

[0003] When winding, the existing anti-wrinkle film pressing device usually uses a tensioning roller to increase the surface tension of the wrapping film to avoid wrinkling after winding. However, the position of most tensioning rollers is fixed by screws, and the surface tension of the wrapping film will change during the winding process. The fixed tensioning roller cannot flexibly adjust the tension of the wrapping film, and the winding roller is not easy to disassemble after winding, which leads to a decrease in work efficiency. In view of the above problems, the technicians in this field have proposed an anti-wrinkle film pressing device for wrapping film production to solve the above problems. Utility Model Content

[0006] Furthermore, the clamping assembly includes two mounting blocks, and the two mounting blocks are respectively rotatably connected to the inner sides of the two side plates, and two limiting grooves are provided inside the mounting blocks, and a spring 2 is fixedly connected inside the limiting groove, and a movable block is fixedly connected to the other end of the spring 2, and a pull rod is fixedly connected to one side of the movable block, and a clamping block is fixedly connected to the other side of the movable block, and clamping grooves are provided on the upper and lower surfaces of both ends of the winding roller.

[0007] Furthermore, a motor is installed on the outer surface of the front side side plate near the pressure roller, and the output end of the motor is fixedly connected to the mounting block.

[0008] Furthermore, the interior of the sliding block is slidably connected to the exterior of the guide rod, and the exterior of the sliding block is slidably connected to the interior of the side plate.

[0009] Furthermore, the other end of the spring is fixedly connected to the inside of the side plate, and the outside of the moving block is slidably connected to the inner wall of the side plate.

[0010] Furthermore, the outside of the movable block is slidably connected to the inside of the limiting groove, and the second set of springs is arranged on the outside of the pull rod.

[0024] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment of an anti-wrinkle film pressing device for the production of winding film, comprising a support table 1, the front and rear sides of the top of the support table 1 are fixedly connected to side plates 2, the outer surfaces of the two side plates 2 are fixedly connected to fixed blocks 3, the top of the fixed block 3 is fixedly connected to an electric telescopic rod 4, the output end of the electric telescopic rod 4 is fixedly connected to a slider 5, a tensioning roller 7 is rotatably connected between the two sliders 5, a guide rod 6 is fixedly connected to the middle position of the inner part of the side plate 2, a limit rod 9 is fixedly connected to the inner part of the left side of the side plate 2, a spring 10 is sleeved on the outer part of the limit rod 9, one end of the spring 10 is fixedly connected to a moving block 11, a pressing roller 8 is rotatably connected between the two moving blocks 11, and a winding roller 13 is installed below the pressing roller 8 through a clamping assembly, the inner part of the slider 5 is slidably connected to the outer part of the guide rod 6, the outer part of the slider 5 is slidably connected to the inner part of the side plate 2, the other end of the spring 10 is fixedly connected to the inner part of the side plate 2, and the outer part of the moving block 11 is slidably connected to the inner side wall of the side plate 2.

[0025] Specifically, the support platform 1 supports the entire device, and the two side panels 2 are fixed on the front and rear sides of the top of the support platform 1, so that the side panels 2 can support part of the structure, and the fixed block 3 supports the electric telescopic rod 4, so that the slider 5 can be pushed to move during its operation, and the guide rod 6 plays a limiting role, so that the two sliders 5 can drive the tensioning roller 7 to move up and down, so that the wrapping film will not be relaxed during winding, and the tensioning force can be flexibly adjusted to adapt to different winding time periods, thereby improving the adaptability of the device, and the limit rod 9 limits the movement of the spring 10 to ensure the stable contraction of the spring 10, so that pressure can be applied to the moving block 11 below, and the pressure roller 8 connected between the two moving blocks 11 can always be in close contact with the surface of the wrapping film, thereby exerting pressure on the wrapping film, pressing it flat, and ensuring that no wrinkles will appear during winding, and by adjusting and coordinating the tensioning roller 7 and the pressure roller 8, the wrapping film is always kept in a tightened state during the winding process, thereby reducing the possibility of wrinkles and ensuring the quality of the product.

[0026] Reference Figure 2 and Figure 5 The clamping assembly includes two mounting blocks 14, which are rotatably connected to the inner side mounting blocks 14 of the two side plates 2 respectively. Two limiting grooves 15 are provided inside the limiting grooves 15, and a spring 17 is fixedly connected inside the limiting grooves 15. The other end of the spring 17 is fixedly connected to a movable block 16, one side of the movable block 16 is fixedly connected to a pull rod 18, and the other side of the movable block 16 is fixedly connected to a clamping block 19. The upper and lower surfaces of both ends of the winding roller 13 are provided with clamping grooves 20, the outside of the movable block 16 is slidably connected to the inside of the limiting grooves 15, the spring 17 is sleeved on the outside of the pull rod 18, the longitudinal section of the clamping block 19 is set to be square, and the outside of the clamping block 19 is slidably connected to the inside of the clamping groove 20 at a similar position.

[0027] Specifically, the mounting block 14 is connected to the two ends of the winding roller 13, and the mounting block 14 is rotatably connected to the side plate 2, so that the winding roller 13 is fixed, and the movable block 16 can be driven to slide inside the limiting groove 15 by pulling the pull rods 18 above and below the mounting block 14, thereby compressing the spring 2 17, wherein the limiting groove 15 can limit the movement of the movable block 16, and the pull rod 18 ensures that the contraction of the spring 2 17 will not deviate, thereby maintaining the stable operation of the structure, and driving the clamping block 19 to disengage from the clamping groove 20 through the movable block 16, so that the two ends of the winding roller 13 are respectively disengaged from the mounting block 14, thereby realizing the rapid disassembly of the winding roller 13, and the winding roller 13 is installed and fixed by clamping, so as to facilitate the rapid disassembly of the winding roller 13, reduce the time wasted during replacement, and thus improve production efficiency.

[0028] Reference Figure 1 and Figure 2 A motor 12 is installed on the outer surface of the front side plate 2 near the pressure roller 8, and the output end of the motor 12 is fixedly connected to the mounting block 14. A reeling roller 21 is rotatably connected between the right adjacent surfaces of the two side plates 2.

[0029] Specifically, the motor 12 is fixed by the side plate 2, so that when the motor 12 is running, it can drive one of the mounting blocks 14 connected to it to rotate, thereby causing the winding roller 13 to rotate, thereby realizing the winding operation. At the same time, the unwinding roller 21 is connected through the two side plates 2, and the wrapping film can be continuously released to complete the winding operation.

[0030] Working principle: When this device is used, the electric telescopic rod 4 on the outside of the two side panels 2 pushes the slider 5 to move, so that when the two sliders 5 move along the guide rod 6, they can drive the tensioning roller 7 to move, so that the tensioning force of the wrapping film is changed, and the tensioning force can be flexibly adjusted during the winding process of the wrapping film to avoid the situation where the wrapping film is loose and causes wrinkles. During the winding process, the pressure roller 8 will fit with the surface of the wrapping film, and the spring 10 can limit the upward movement of the moving block 11, so that the pressure roller 8 is driven by the two moving blocks 11 to fit tightly with the surface of the wrapping film, exert pressure on the wrapping film, and flatten its surface, thereby ensuring that the wrapping film does not slide during the winding process, and the winding effect is good.

[0031] By pulling the pull rods 18 at the upper and lower parts of the mounting block 14, the movable block 16 can be driven to slide inside the limiting groove 15, thereby compressing the spring 2 17, and the movable block 16 drives the clamping block 19 to disengage from the clamping groove 20, so that the winding roller 13 can be removed from the mounting blocks 14 at both ends respectively, so as to realize the quick disassembly of the winding roller 13. When installing, it is only necessary to repeat the above operation, and after the clamping block 19 is aligned with the corresponding clamping groove 20, release the pull rod 18 to restore the spring 2 17 to its original state, thereby pushing the clamping block 19 to engage with the clamping groove 20, and fixing the winding roller 13. Through the above operation, the time for replacing the winding roller 13 is reduced, and the work efficiency is improved.
