Description

Technical Field

[0001] This application relates to the technical field of winding devices, and specifically relates to a winding device for PE shrink film. Background Art

[0002] PE shrink film is an industrial packaging film product, which has the characteristics of high tensile strength, large elongation, good self-adhesion, and high transparency. It is used for manual winding film and can also be used for machine winding film, and can be widely used in the centralized packaging of various goods.

[0003] The existing patent (publication number: CN220617767U) discloses a winding device for PE shrink film, including a workbench and a winding roller. One side of the workbench is installed with a moving plate through a moving mechanism, and one side of the moving plate is installed with a cross block through a rotating mechanism. One side of the winding roller is fixedly installed with a first connecting rod, and a cross groove is opened on one side of the first connecting rod. The inner wall of the cross groove is matched with the surface of the cross block. The top of the workbench is fixedly installed with a fixing plate, and an installation mechanism is arranged on one side of the fixing plate. By inserting the second connecting rod into the inner wall of the positioning groove and placing the first connecting rod on the inner wall of the arc groove for positioning, the cross block is driven by the first motor to move, so that the cross block reaches the inner wall of the cross groove for installation. By driving the cross block to move by the first motor, the cross block leaves the inner wall of the cross groove, and the winding roller can be taken out, achieving the purpose of facilitating the quick installation and disassembly of the winding roller.

[0004] Since the PE shrink film needs to maintain a high degree of flatness and stability during the winding process to ensure the final packaging effect, in the above device, only relying on the rotational force of the winding roller for winding, there is a lack of a special limiting mechanism to restrain and stabilize the position of the shrink film during the winding process. This lack of design leads to the shrink film being prone to deviation due to external factors or uneven self-tension during actual operation, resulting in uneven winding and poor packaging effect. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a winding device for PE shrink film, which has the advantages of neat winding and solves the problems raised in the background art.

[0006] To achieve the above object, this application provides the following technical solution: A winding device for PE shrink film, including a bottom plate, two support plates are fixedly connected to the upper surface of the bottom plate, a winding roller is arranged between the two support plates, a chute is opened inside the winding roller, and two symmetrically arranged limiting discs are slidably connected inside the chute. The limiting discs are slidably sleeved on the outer surface of the winding roller;

[0007] A rotating shaft is rotatably connected to the inside of each of the two support plates. A clamping groove is provided at one end of each of the two rotating shafts close to each other. A connecting block is inserted into each clamping groove.

The combined design of the limiting disc and the bidirectional threaded rod enables the user to conveniently adjust the distance between the two limiting discs to adapt to winding PE shrink films of different sizes, enhancing the versatility and flexibility of the equipment. Through the design of the connecting block, clamping groove, spring and handle, the quick installation and disassembly of the winding roller are realized, which not only simplifies the operation process, but also reduces the maintenance cost and improves the work efficiency.

[0009] A connecting disc is slidably sleeved on the outer surface of each of the two connecting blocks. A plurality of connecting rods are fixedly connected to one side of the two connecting discs close to each other. The other end of each connecting rod is fixedly connected to the winding roller.

[0010] Through the arrangement of the connecting disc and the connecting rod, the purpose of driving the winding roller to rotate during the rotation of the rotating shaft can be achieved.

[0011] A spring is installed between each connecting block and the inner wall of the clamping groove close to it.

[0012] Through the arrangement of the spring, the purpose of stably inserting the connecting block into the connecting disc can be achieved.

[0013] Two handles are fixedly connected to the outer surface of each of the two connecting blocks.

[0016] Through the arrangement of the bidirectional threaded rod, the purpose of adjusting the distance between the two limiting discs can be achieved, facilitating the winding of PE shrink films of different sizes.

[0017] Both ends of the bidirectional threaded rod are fixedly connected with a turntable.

[0018] Through the arrangement of the turntable, the purpose of driving the bidirectional threaded rod to rotate can be achieved.

[0019] The left end of the left rotating shaft is fixedly connected to the output end of an external motor.

[0020] By setting an external motor, power can be provided for the rotation of the rotating shaft.

[0021] The outer surfaces of both of the said turntables are knurled.

[0022] By knurling the outer surface of the turntable, the friction coefficient can be effectively increased, facilitating the user to rotate it.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For the winding device of a kind of PE shrink film, by arranging a chute and a slidably connected limit disk inside the winding roller, the position of the shrink film during winding is effectively restricted, preventing the deviation phenomenon caused by external factors or uneven self-tension, ensuring the flatness and stability of winding, thereby improving the packaging effect and product quality.

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 4 In this embodiment, a winding device for a PE shrink film includes a bottom plate 1. Two support plates 2 are fixedly connected to the upper surface of the bottom plate 1. A winding roller 3 is arranged between the two support plates 2. A chute 4 is opened inside the winding roller 3. Two symmetrically arranged limit disks 5 are slidably connected inside the chute 4. The limit disks 5 are slidably sleeved on the outer surface of the winding roller 3. A bidirectional threaded rod 13 is rotatably connected inside the winding roller 3. The two limit disks 5 are respectively threadedly connected to both ends of the bidirectional threaded rod 13. Through the setting of the bidirectional threaded rod 13, the purpose of adjusting the distance between the two limit disks 5 can be achieved, facilitating the winding of PE shrink films of different sizes.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 Rotating shafts 6 are rotatably connected inside both support plates 2. Slots 7 are opened at one end of the two rotating shafts 6 close to each other. A connecting block 8 is inserted into each slot 7. Connecting disks 9 are slidably sleeved on the outer surfaces of the two connecting blocks 8. A plurality of connecting rods 10 are fixedly connected to one side of the two connecting disks 9 close to each other. The other end of each connecting rod 10 is fixedly connected to the winding roller 3. Through the setting of the connecting disks 9 and the connecting rods 10, the purpose of driving the winding roller 3 to rotate during the rotation of the rotating shaft 6 can be achieved.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 A spring 11 is installed between each connecting block 8 and the inner wall of the slot 7 close to it. Through the setting of the spring 11, the purpose of stably inserting the connecting block 8 into the connecting disk 9 can be achieved. Two handles 12 are fixedly connected to the outer surfaces of the two connecting blocks 8. Through the setting of the handles 12, the purpose of pulling the connecting block 8 to move and releasing the limit on the connecting disk 9 can be achieved, thereby achieving the effect of quickly disassembling the winding roller 3.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 Rotary disks 14 are fixedly connected to both ends of the bidirectional threaded rod 13. Through the setting of the rotary disks 14, the purpose of driving the bidirectional threaded rod 13 to rotate can be achieved. The left end of the left rotating shaft 6 is fixedly connected to the output end of an external motor. Through the setting of the external motor, power can be provided for the rotation of the rotating shaft 6. The outer surfaces of the two rotary disks 14 are knurled. Through the knurling of the outer surfaces of the rotary disks 14, the friction coefficient can be effectively increased, facilitating the user to rotate.

[0036] A winding device for a PE shrink film in this embodiment effectively restricts the position of the shrink film during the winding process by arranging a chute 4 and a slidably connected limiting disc 5 inside the winding roller 3, preventing the deviation phenomenon caused by external factors or uneven self-tension, ensuring the flatness and stability of winding, thereby improving the packaging effect and product quality. The combined design of the limiting disc 5 and the bidirectional threaded rod 13 enables users to conveniently adjust the distance between the two limiting discs 5 to adapt to winding PE shrink films of different sizes, enhancing the versatility and flexibility of the equipment. Through the design of the connecting block 8, the clamping groove 7, the spring 11 and the handle 12, the quick installation and disassembly of the winding roller 3 are realized, which not only simplifies the operation process, but also reduces the maintenance cost and improves the work efficiency.

[0037] The working principle of the above embodiment is as follows: Place the winding roller 3 between the support plates 2. Through the plug-in fit of the connecting block 8 and the clamping groove 7 and the fastening effect of the spring 11, the stable installation of the winding roller 3 is realized. According to the size of the PE shrink film to be wound, rotate the turntable 14 to drive the bidirectional threaded rod 13 to rotate, and then adjust the distance between the two limiting discs 5 to ensure that the limiting discs 5 can closely fit both sides of the shrink film to play a limiting role. Fix the left end of the left rotating shaft 6 to the output end of an external motor to ensure that the motor can provide stable rotational power for the rotating shaft 6. Start the external motor, and the output end of the motor drives the rotating shaft 6 to rotate. Due to the arrangement of the connecting disc 9 and the connecting rod 10, the rotation of the rotating shaft 6 will drive the winding roller 3 to rotate synchronously. As the winding roller 3 rotates, the PE shrink film is gradually wound onto the winding roller 3. Under the adjustment of the bidirectional threaded rod 13, the limiting discs 5 keep closely fitting both sides of the shrink film, effectively preventing the deviation of the shrink film during the winding process.
