Description

Technical Field

[0001] This invention relates to the field of energy-saving and environmental protection technology for saving the amount of self-adhesive film material, and more specifically to a device and method for continuous recycling of self-adhesive film release tape. Background Technology

[0002] In the self-adhesive film industry, the use of release liner tape (hereinafter referred to as "release liner tape") is guided by a constant theme: pursuing efficient equipment operation, environmental protection, and a circular economy, namely, efficient and environmentally friendly recycling and reuse of release liner tape. However, existing recycling methods suffer from the following problems:

[0003] 1. Purely manual recycling: The disadvantages are that it requires a lot of labor and the working environment is not friendly;

[0004] 2. Machine winding with manual splicing for assisted recycling into rolls: The disadvantage is that the machine must be stopped approximately every 15 minutes.

[0005] 3. Directly crush the release tape into powder: The disadvantage is that the recovery of chemical elements from the powder is still limited, and the subsequent recycling technology is not yet ready for industrialization. Summary of the Invention

[0006] 1. The technical problem that the invention aims to solve

[0007] To address the aforementioned problems in the recycling and reuse of release tape in existing technologies, this invention provides a continuous recycling device and method for release tape of self-adhesive film material. This allows the joint of each roll of release tape to automatically switch to a new rewinding air shaft after winding, automatically connecting and then automatically winding. When the winding diameter approaches a set value, it moves closer to another new rewinding air shaft, repeating the cycle continuously. This achieves the goal of recycling release tape without human intervention and without stopping the machine during recycling.

[0008] 2. Technical Solution

[0009] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0010] A continuous recycling device for release tape of self-adhesive film material includes a mounting plate frame, a slide rail hole, a double rotating roller assembly, a guide roller assembly, a feed roller, a cutter, a right take-up air shaft, and a left take-up air shaft. The mounting plate frame is placed vertically. The slide rail hole is opened horizontally on the mounting plate frame between the right and left take-up air shafts. The double rotating roller assembly is slidably connected in the slide rail hole. The right and left take-up air shafts are arranged horizontally and rotatably connected to the mounting plate frame. The guide roller assembly is fixedly connected to the mounting plate frame above the right and left take-up air shafts. The feed roller is fixedly connected to the feed end of the mounting plate frame. The cutter is fixedly connected to the mounting plate frame below the slide rail hole. In practical use, it breaks away from the past requirement of manually touching the release tape and manually pasting the release tape head. Instead, the joint of each roll of release tape will automatically switch to another new take-up air shaft, automatically connect, and then automatically rewind. When the winding diameter approaches the set value, it will automatically move closer to another new take-up air shaft, repeating the cycle without human intervention.

[0011] A further self-adhesive film release tape continuous recycling device includes a dual rotating roller assembly comprising a roller frame, rotating rollers and a rotating shaft. The two rotating rollers are rotatably connected in parallel to the inner side of the roller frame, and the rotating shaft is fixedly connected to the outer side of the roller frame. The roller frame is slidably connected to the slide rail hole through the rotating shaft. The release tape is wound up after being moved back and forth between the right winding air shaft and the left winding air shaft.

[0012] The further self-adhesive film release tape continuous recycling device, the double rotating roller assembly also includes a transverse slide and a transverse slider; the transverse slide is fixedly connected to the back of the mounting plate frame, and the transverse slider is slidably connected to the transverse slide; after the rotating shaft passes through the slide rail hole, it is hinged to the bottom of the transverse slider and moves laterally in a directional manner to ensure the stability and accuracy of the lateral movement.

[0013] The further self-adhesive film release belt continuous recycling device also includes a buffer roller assembly fixedly connected to the mounting plate frame to adjust the tension and storage amount of the self-adhesive film.

[0014] The further improved self-adhesive film release tape continuous recycling device includes a buffer roller assembly comprising a fixed buffer roller assembly and a movable buffer roller assembly; the mounting frame is also fixedly connected to a vertical slide rail, on which a vertical slider is slidably connected; the fixed buffer roller assembly is fixedly connected to the mounting frame, and the movable buffer roller assembly is fixedly connected to the vertical slider; under the coordination of the control unit, the movable buffer roller assembly moves within the area set by the mounting frame, which can form a stable tension and appropriate storage capacity for the release tape.

[0015] The further improved self-adhesive film release tape continuous recycling device has a feeding roller with a reversing double roller structure at a 90° angle to each other, which can be adaptively adjusted and reversed according to the material direction of the release tape.

[0016] Further, a continuous recycling device for release tape of self-adhesive film material is provided, with double-sided adhesive layers pasted on the shaft surfaces of the right and left take-up air shafts, which can automatically paste the release tape roll head.

[0017] The further self-adhesive film release tape continuous recycling device has a guide roller assembly consisting of parallel double guide rollers that guide the material while simultaneously flattening the release tape.

[0018] A recycling method for a self-adhesive film release tape continuous recycling device includes the following steps:

[0019] The release belt is fed from the feed roller to the guide roller assembly;

[0020] The guide roller assembly guides the release belt between the two rotating rollers;

[0021] The release belt wraps around the two rotating rollers to the left take-up air shaft;

[0022] The left take-up air shaft winds the air to the predetermined thickness diameter;

[0023] The two rotating rollers move to the right along the transverse slide rail holes to the right winding air shaft;

[0024] The cutter cuts the release tape;

[0025] The release strip near the right take-up air shaft forms the starting point of a new roll, and the right take-up air shaft rewinds;

[0026] The two rotating rollers move to the left along the transverse slide rail hole to the middle of the slide rail hole, completing the replacement winding of the left and right take-up air shafts.

[0027] In a further recycling method, the two rotating rollers are initially positioned at an angle of 60° to the horizontal direction; when the left and right take-up air shafts are replaced during take-up, the two rotating rollers rotate 240° clockwise to maintain the release belt tension and flattening state between the two rollers.

[0028] 3. Beneficial effects

[0029] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0030] The self-adhesive film release tape continuous recycling device of the present invention breaks away from the past requirement of manual contact with the release tape and manual pasting of the release tape head. Instead, the joint of each roll of release tape can be automatically switched to another new take-up air expansion shaft, automatically connected, and then automatically rewound. When the rewound diameter approaches the set value, it automatically moves closer to another new take-up air expansion shaft, repeating the cycle without human intervention. Moreover, the recycling method is faster and more convenient, more worker-friendly, and the equipment is more efficient. Compared to the previous method that required an average of 15 minutes of machine downtime, the recycling efficiency is increased by more than 30%. Attached Figure Description

Detailed Implementation

[0038] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with the accompanying drawings.

[0039] Example 1

[0040] The self-adhesive film release tape continuous recycling device in this embodiment, such as Figure 1 , 2As shown in Figure 4, the assembly includes a mounting frame 1, a slide rail hole 8, a double rotating roller assembly 7, a guide roller assembly 6, a feed roller 12, a steering roller 5, a cutter 4, a right take-up air shaft 2, and a left take-up air shaft 3. The mounting frame 1 is placed vertically. The slide rail hole 8 is opened horizontally on the mounting frame 1 between the right take-up air shaft 2 and the left take-up air shaft 3. The right take-up air shaft 2 and the left take-up air shaft 3 are arranged horizontally and vertically rotatably connected to the mounting frame 1. Their driving components are assembled on the back of the mounting frame 1. The driving principle and structure are existing technologies and will not be described in detail. The guide roller assembly 6 and the steering roller 5 are fixedly connected to the mounting frame 1 above the right take-up air shaft 2 and the left take-up air shaft 3. The feed roller 12 is fixedly connected to the left feed end of the mounting frame 1. The cutter 4 is fixedly connected to the mounting frame 1 below the slide rail hole 8. The cutter 4 is usually driven by a telescopic cylinder for cutting.

[0041] like Figure 5 As shown, the dual rotating roller assembly 7 includes a roller frame 71, rotating rollers 72 and a rotating shaft 73. The two rotating rollers 72 are rotatably connected to the inner side of the roller frame 71 in parallel, and the rotating shaft 73 is fixedly connected to the outer side of the roller frame 71. The roller frame 71 is slidably connected to the slide rail hole 8 through the rotating shaft 73. The release belt 100 is wound up after being moved back and forth between the right take-up air shaft 2 and the left take-up air shaft 3.

[0042] The recycling method of the self-adhesive film release tape continuous recycling device in this embodiment includes the following steps:

[0043] S1, release belt 100 is fed into guide roller assembly 6 by feed roller 12 and guide roller 5 in sequence;

[0044] S2, guide roller assembly 6 guides release belt 100 to between two rotating rollers 72;

[0045] S3, release belt 100 wraps around the two rotating rollers 72 to the left take-up air shaft 3;

[0046] S4. Left winding air shaft 3 winds up to the predetermined thickness diameter;

[0047] S5. The two rotating rollers 72 move to the right along the transverse slide rail hole 8 to the right winding air shaft 2;

[0048] S6, Cutter 4 cuts the release strip 100;

[0049] S7. The release strip 100 near the right take-up air shaft 2 forms the starting point of a new roll, and the right take-up air shaft 2 takes up the roll.

[0050] S8. The two rotating rollers 72 move to the left along the transverse slide rail hole 8 to the middle of the slide rail hole 8, completing the replacement winding of the right winding air shaft 2 to the left winding air shaft 3. Conversely, the replacement winding of the left winding air shaft 3 to the right winding air shaft 2 is completed.

[0051] Example 2

[0052] The self-adhesive film release tape recycling device in this embodiment has the same basic structure as in Embodiment 1, with the following differences or improvements: Figure 1 , 2 As shown in Figures 3, 4, and 5, the dual rotating roller assembly 7 also includes a transverse slide 74 and a transverse slider 75. The transverse slide 74 is fixedly connected to the back of the mounting plate frame 1, and the transverse slider 75 is slidably connected to the transverse slide 74. After the rotating shaft 73 passes through the slide rail hole 8, it is hinged to the bottom of the transverse slider 75 and moves laterally in a directional manner to ensure the stability and accuracy of the lateral movement.

[0053] To facilitate the steering of the dual rotating roller assembly 7, it is preferable to assemble a steering cylinder at the bottom of the transverse slider 75, replacing the rotating shaft 73 with the output shaft of the steering cylinder, and the output shaft is fixedly connected to the side of the roller frame 71 facing the transverse slide rail hole 8.

[0054] It also includes a buffer roller assembly fixedly connected to the mounting frame 1 to adjust the tension and storage amount of the self-adhesive film material. The buffer roller assembly includes a fixed buffer roller assembly 10 and a movable buffer roller assembly 9; the mounting frame 1 is also fixedly connected to a vertical slide rail 11, on which a vertical slider 91 is slidably connected; the fixed buffer roller assembly 10 is fixedly connected to the top of the mounting frame 1, and the movable buffer roller assembly 9 is fixedly connected to the inner side of the vertical slider 91; the movable buffer roller assembly 9, under the coordination of the control unit, moves within the area defined by the mounting frame 1, thereby creating a stable tension and suitable storage amount for the release belt 100. The number of fixed buffer rollers and movable buffer rollers in the fixed buffer roller assembly 10 and the movable buffer roller assembly 9 can be adjusted accordingly based on the required buffer amount. Figure 1 The images show three items arranged side by side.

[0055] The feed roller 12 is a reversing double roller structure with a 90° angle between them. It works in conjunction with the steering roller 5 and can be adaptively adjusted and reversed according to the material direction of the release belt 100.

[0056] Double-sided adhesive layer 15 is pasted on the shaft surfaces of the right take-up air shaft 2 and the left take-up air shaft 3 to stick the roll head of the release tape 100 after being cut by the cutter 4.

[0057] The back of the mounting plate frame 1 is equipped with a servo geared motor assembly, a transition wheel assembly 14, a tension wheel assembly 16, and an air shaft brake 13. The output end of the servo geared motor passes through the transition wheel assembly 14 and the tension wheel assembly 16 via a synchronous belt and is connected to the right take-up air shaft 2 and the left take-up air shaft 3. On the back of the mounting plate frame 1, near the shaft surface of the right take-up air shaft 2 and the left take-up air shaft 3, an air shaft brake 13 is installed.

[0058] Both the right take-up air shaft 2 and the left take-up air shaft 3 are driven by one-way bearings to avoid the right take-up air shaft 2 and the left take-up air shaft 3 rotating at the same time due to the timing belt.

[0059] The guide roller assembly 6 consists of two parallel guide rollers that guide the material while simultaneously flattening the release belt 100.

[0060] The cutter 4 can perform telescopic cutting via a telescopic cylinder mounted on the mounting plate 1, and the cutter 4 is fixedly connected to the output shaft of the telescopic cylinder. The mounting plate 1 is also equipped with existing photoelectric detection, control unit, pneumatic system, protective cover and bracket and other supporting functional components, which will not be described in detail here.

[0061] The recycling method of the self-adhesive film release tape continuous recycling device in this embodiment includes the following steps:

[0062] like Figure 6 As shown: The initial position of the dual rotating roller assembly 7 is in the middle of the slide rail hole 8 between the right take-up air shaft 2 and the left take-up air shaft 3, with an angle α of 60° with the horizontal direction.

[0063] Release tape 100 enters Figure 1 The feed roller 12 shown is designed to work in conjunction with the guide roller 5 to provide adaptive guidance based on the direction of the release belt 100. The release belt 100 then passes around each roller in the buffer moving roller group 9 and the buffer fixed roller group 10. The number of rollers in the buffer roller group is configured according to the tension and buffer amount to ensure that the release belt 100 is in a constant state at all times.

[0064] like Figure 7 As shown: Release belt 100 arrives at guide roller assembly 6, changes direction, enters the space between two guide rollers, and is guided towards double rotating roller assembly 7. The initial position of double rotating roller assembly 7 maintains an angle of 60° with the horizontal direction. The rotation direction is determined according to whether the air shaft to be wound is the left or right group; taking the initial winding with the left winding air shaft 3 as an example... Figure 7 The direction shown is clockwise.

[0065] like Figure 8-9 As shown: When the winding is close to the predetermined diameter and needs to be switched to the right group, the double rotary roller assembly 7 first moves to the right and moves to the right along the transverse slide 74. At this time, the left winding air shaft 3 is still winding, and the release belt 100 is still in normal tension. The double rotary roller assembly 7 continues to move, and the double-sided adhesive layer 15 on the right winding air shaft 2 is ready. The double rotary roller assembly 7 moves to be close to the right winding air shaft 2, and the double-sided adhesive is firmly attached to the release belt 100 to form the starting point of a new roll.

[0066] like Figure 9-14As shown: The left take-up air shaft 3 stops rotating, and the air shaft brake 13 of the left take-up air shaft 3 is engaged to prevent the left take-up air shaft 3 from continuing to rotate due to rotational inertia. At the same time, the telescopic cylinder drives the cutter 4 to rush out and cut the release belt 100. The left take-up air shaft 3 has been disengaged from the take-up state, and the entire roll on the left take-up air shaft 3 is removed. The right take-up air shaft 2 rotates to take up the roll. After the right take-up air shaft 2 rotates twice to stabilize the roll, the double rotating roller assembly 7 moves to the left along the transverse slide 74 and stops moving at the middle position. It then rotates 240° clockwise and... Maintaining this angle, the right take-up air shaft 2 continues to rotate and rewind until it approaches the predetermined diameter. When switching to the left group, the double rotating roller assembly 7 moves to the left group, approaches, and presses against the left take-up air shaft 3. The double-sided adhesive on it adheres to the release tape 100, and the cutter 4 extends to cut the release tape 100. The air shaft brake 13 of the right take-up air shaft 2 brakes, and the right group disengages from winding. The left take-up air shaft 3 continues to rotate and rewind. The double rotating roller assembly 7 moves to the right group, rotates 240° counterclockwise, and maintains this angle, returning to the previous position. Figure 7 The initial state shown prepares the system for the next cycle.

[0067] The self-adhesive film release tape continuous recycling device and recycling method of this embodiment breaks the previous requirement of manual contact with the release tape 100 and manual pasting of the release tape 100 head. Instead, the joint of each roll of release tape 100 can be automatically switched to another new take-up air shaft, automatically connected by double-sided adhesive layer 15, and then automatically rewound. When the rewound diameter is close to the set value, it automatically moves closer to another new take-up air shaft, and repeats continuously without human intervention. Moreover, the recycling method is faster and more convenient, more friendly to the working environment of workers, and more efficient in equipment use. Compared with the previous method of stopping the machine once every 15 minutes on average, the recycling efficiency has been improved by more than 30% according to the test.

[0068] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
