Description

Technical Field

[0001] This utility model relates to the field of release film winding technology, specifically a high-speed PET release film winding machine with tension self-adaptation. Background Technology

[0002] PET release film, also known as polyethylene terephthalate release film, is a polymer material made by coating the surface of PET plastic with silicone oil or fluorine materials. PET release film has good transparency, which can clearly show the appearance of the covered object; its thickness ranges widely, from as thin as 0.015 mm to as thick as 0.25 mm. It has high tensile strength and is not easily torn or damaged during production, processing and use. It can withstand a certain amount of external force. During production and processing, it is usually wound up by a winding machine.

[0003] In the field of release film winding, existing winding equipment may cause the release film to loosen during the winding process due to its tensile strength. This can lead to wrinkles and twists in the release film, affecting its overall quality and aesthetics. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that existing release films have a certain tensile strength, they may become loose during the winding process, resulting in wrinkles and twists, which affects the overall quality and aesthetics of the release film.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-speed PET release film rewinder with tension adaptive function, characterized in that it includes:

[0008] An assembly frame is provided, with a winding assembly fixedly installed at its rear end and a receiving roller rotatably connected to the front end of the assembly frame. A tensioning mechanism is provided on one side of the receiving roller.

[0009] The tensioning mechanism includes an electric push rod, which is embedded in the top of the assembly frame. A push block is fixedly installed at the power output end of the electric push rod. A ball bearing is embedded inside the push block, and a rotating rod extends out of the ball bearing. A contact cylinder is sleeved on one end of the rotating rod that extends out of the ball bearing.

[0010] As a further improvement of this utility model: an installation sleeve is embedded in one side of the bottom of the inner part of the assembly frame, and a through rod protrudes from the inside of the installation sleeve.

[0011] As a further improvement of this utility model: the inside of the mounting sleeve is provided with a mounting groove, and a spring is embedded inside the mounting groove.

[0012] As a further embodiment of this utility model: a retaining ring is fixedly installed at one end of the protruding rod that enters the mounting sleeve, and a retaining groove is provided inside the mounting groove corresponding to the position of the retaining ring.

[0013] As a further improvement of this utility model: a rotating block is rotatably connected to one side of the outer wall of the assembly frame, and a limit mechanism is provided at one end of the rotating block.

[0016] As a further improvement of this utility model: a support shaft is fixedly installed inside the groove, and a roller is rotatably connected to the outer wall of the support shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of an electric push rod, mounting sleeve, through rod, and spring, achieves an adaptive tensioning effect during the release film winding process, maintaining uniform tension according to different conditions. This avoids problems such as slackness, wrinkles, or excessive stretching, which affect the overall aesthetics and improve the flatness and quality of the winding, thus benefiting subsequent processing and use.

[0019] 2. This utility model, through the design of a bidirectional threaded rod, a movable frame, an assembly plate, a support shaft, and a roller, can be adjusted according to the width of the release film, always achieving a limiting effect and preventing deviation during the winding process, which would lead to misalignment and stacking after winding, causing wrinkles due to mutual interference.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a high-speed winding machine for PET release film with tension adaptive, including: an assembly frame 1, a winding assembly 2 fixedly installed at the rear end of the assembly frame 1, a receiving roller 3 rotatably connected to the front end of the inner part of the assembly frame 1, and a tensioning mechanism 4 provided on one side of the receiving roller 3.

[0031] The tensioning mechanism 4 includes an electric push rod 401, which is embedded in the top of the assembly frame 1. A push block 402 is fixedly installed at the power output end of the electric push rod 401. A ball bearing 403 is embedded inside the push block 402. A rotating rod 404 extends out of the ball bearing 403. A contact cylinder 405 is sleeved on one end of the rotating rod 404 that extends out of the ball bearing 403.

[0032] Specifically, an installation sleeve 406 is embedded in one side of the bottom of the assembly frame 1, and a through rod 407 extends out of the inside of the installation sleeve 406.

[0033] Furthermore, by installing the sleeve 406 and the through rod 407 to form a telescopic structure, displacement space can be reserved for the lower contact cylinder 405.

[0034] Specifically, the mounting sleeve 406 has a mounting groove 408 inside, and a spring 409 is embedded inside the mounting groove 408.

[0035] Furthermore, the elastic push of the spring 409 can abut against the through rod 407, thereby allowing the corresponding abutment cylinder 405 above to pull the release film downward. When it becomes loose, the spring 409 can straighten it, achieving self-adjustment.

[0036] Specifically, a retaining ring 411 is fixedly installed at one end of the protruding rod 407 that is inserted into the mounting sleeve 406, and a retaining groove 410 is provided inside the mounting groove 408 corresponding to the position of the retaining ring 411.

[0037] Furthermore, by engaging and sliding the retaining ring 411 with the retaining groove 410, displacement space is reserved during tensioning, while avoiding excessive stretching of the release film that could cause the protruding rod 407 to detach from the contact cylinder 405.

[0038] In use, two sets of push blocks 402, ball bearings 403, rotating rods 404, and abutment cylinders 405 are set up. With the help of receiving rollers 3, the release film is wound three times and then wound up by winding assembly 2. The winding assembly 2 is equipped with components such as motors and winding rollers. This is existing technology and will not be described in detail here. The upper electric push rod 401 drives the corresponding push block 402, so that the upper abutment cylinder 405 is automatically adjusted according to the tension sensor embedded in the abutment cylinder 405 (or assembled on the release film travel path). With the help of the sleeve 406, the through rod 407, and the spring 409, the lower abutment cylinder 405 can pull the release film downward. When there is slight looseness and the tension sensor cannot detect it, the release film can be straightened. With the help of the slot 410 and the retaining ring 411, the through rod 407 is prevented from disengaging.

[0039] In summary, the elastic extension and retraction of the spring 409 initially pulls the release film through the lower contact cylinder 405, which can straighten the film when a small tension force occurs, preventing it from becoming loose. When the looseness is too large, the tension sensor installed in the upper contact cylinder 405 senses the tension and sends a signal to the device control end, which controls the electric push rod 401 to extend and retract, thereby tensioning the release film and enabling adaptive adjustment according to the situation.

[0040] Example 2

[0041] Please see Figure 1 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a high-speed PET release film rewinder with tension adaptive function.

[0042] Specifically, a rotating block 5 is rotatably connected to one side of the outer wall of the assembly frame 1, and a limit mechanism 6 is provided at one end of the rotating block 5.

[0043] Furthermore, the limiting mechanism 6 can limit the release film from both sides to prevent displacement or misalignment during the winding process.

[0044] Specifically, the limiting mechanism 6 includes a bidirectional threaded rod 601, which is fixed to one end of the rotating block 5. The bidirectional threaded rod 601 is slidably connected to a movable frame 602 on the outer wall of one end of the assembly frame 1. A limiting groove 603 is opened on the other side of the bottom inside the assembly frame 1.

[0045] Furthermore, by manually adjusting the bidirectional threaded rod 601 through the rotating block 5, the moving frame 602 can slide stably along the limiting groove 603 and move from both sides toward the release film. The adjustment is made according to the width of the release film to improve applicability.

[0046] Specifically, an assembly plate 604 is fixedly installed on the outer wall of the movable frame 602, and a groove 605 is provided on the outer wall of the assembly plate 604.

[0047] Furthermore, the assembly plate 604 moves along with the moving frame 602, thereby fitting and limiting the release film and preventing deviation during the conveying process.

[0048] Specifically, a support shaft 606 is fixedly installed inside the groove 605, and a roller 607 is rotatably connected to the outer wall of the support shaft 606.

[0049] Furthermore, by rotating the roller 607 on the outer wall of the support shaft 606 to abut against the release film, excessive friction can be avoided while limiting the movement, thus preventing the release film edges from curling.

[0050] In use, first adjust the rotating block 5 according to the width of the release film to make the bidirectional threaded rod 601 rotate, so that the two moving frames 602 slide along the limiting groove 603 and drive the assembly plate 604 to fit the release film. The roller 607, which is fixedly connected to the support shaft 606 inside the groove 605, rotates to resist the release film to avoid excessive friction and damage.

[0051] In summary, by rotating the roller 607 against both sides of the release film, it is possible to prevent the release film from shifting during the winding process, which could lead to misalignment and overlapping after winding, causing wrinkles due to mutual interference. It also prevents excessive friction during winding, which could cause the release film to curl or be damaged, thus improving smoothness. At the same time, by adjusting the moving frame 602 to follow the width of the release film, the versatility and applicability of the application are further improved.
