Description

Technical Field

[0001] This utility model specifically relates to a degumming device. Background Technology

[0002] Disposable medical sheets are commonly used hygiene consumables in medical institutions, primarily used to cover surfaces such as examination beds, treatment beds, and operating tables, providing patients with a clean and isolated contact interface. Double-sided tape (covered with release paper) affixed to the edges or specific locations of the sheet is mainly used to secure its position. The release paper must be removed before applying the double-sided tape to the mattress or bed surface. This prevents the sheet from wrinkling, sliding, or shifting when the patient turns over or moves, ensuring the sheet always covers the bed surface smoothly.

[0003] However, the release paper remains adhered to the adhesive surface at both the ends and edges of the double-sided tape, meaning the tape is a double layer of adhesive throughout, making it extremely difficult to find a "peeling point." Whether a gloved doctor, an unarmed operator, or in a dry / humid environment, methods such as prying with fingernails or rubbing with fingertips are required. This process is limited by insufficient friction between the fingers and a smooth surface, easily leading to uneven force that can tear the release paper or deform the adhesive surface, requiring a considerable amount of time to peel off. During surgery, "spending a considerable amount of time separating the double-sided tape from disposable bed sheets" is unacceptable. Therefore, how to help people quickly separate the "release paper from the surface of the double-sided tape" is a problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a de-adhesive device that addresses the shortcomings of the prior art by integrating double-sided adhesive feeding, adhesive surface cutting, film material conveying and adhesive surface separation functions, thereby achieving automated peeling of the adhesive surface of the double-sided adhesive head from the release paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a de-adhesive device, characterized in that it includes a de-adhesive frame, on which a double-sided adhesive feeding component, an adhesive surface separation component, an adhesive surface separation component, and an adhesive layer feeding component are installed. The double-sided adhesive feeding component can transport double-sided adhesive to the adhesive surface separation component. The adhesive surface separation component can cut the adhesive surface of the double-sided adhesive and transport the cut double-sided adhesive to the adhesive surface separation component. The adhesive layer feeding component can transport a film material with an "adhesive surface" to the adhesive surface separation component. When the cut double-sided adhesive is transported to the adhesive surface separation component, the adhesive surface of the double-sided adhesive faces the film material with an "adhesive surface," and the adhesive surface separation component can adhere the cut adhesive surface to the film material with an "adhesive surface."

[0006] Using the above technical solution, the adhesive cutter serves as an integrated carrier. The double-sided adhesive feeding component continuously feeds the roll of double-sided adhesive (including release paper and adhesive surface) to the adhesive surface separation component. The adhesive surface separation component cuts the adhesive surface of the double-sided adhesive according to a predetermined length (the release paper remains continuous), forming a fixed-length adhesive surface segment (to be separated) and a continuous adhesive surface segment (retained on the release paper for subsequent bonding with disposable bed sheets and other products). Subsequently, the cut double-sided tape (including release paper and fixed-length adhesive segments, and continuous adhesive segments) is conveyed to the adhesive separation component. At the same time, the adhesive layer feeding component conveys the "adhesive-adhesive film material" (such as film, paper, etc., only requiring the "adhesion between the film material and the adhesive surface" to be stronger than the "adhesion between the release paper and the adhesive surface") to the adhesive separation component, so that the film material contacts the adhesive side of the double-sided tape. The adhesive separation component only adheres the fixed-length adhesive segments (that need to be separated) to the surface of the film material. Finally, the film material carries away the fixed-length adhesive segments (that need to be separated), while the continuous adhesive segments remain on the release paper, realizing the automated peeling of "only the adhesive surface of the double-sided tape head is separated from the release paper". Thus, the double-sided tape head is the "release paper", eliminating the need for manual repeated rubbing to find the separation point. In summary, the double-sided tape head after processing with this solution is a release paper. In actual use (such as when medical staff are laying bed sheets), the release paper head can be directly grasped to quickly separate the release paper from the adhesive surface, reducing operation time. It is especially suitable for scenarios with high requirements for operation efficiency, such as surgery.

[0007] The aforementioned degumming device can be further configured as follows: the adhesive separation assembly includes a first guide roller and an adhesive separation roller that are parallel to each other. The two ends of the first guide roller are rotatably mounted on the adhesive break frame through bearings. At least one set of pressing members are linked on the adhesive separation roller. The pressing members are provided with arc-shaped pressing portions extending outward. The adhesive separation roller is linked with a first driving component for driving the adhesive separation roller to rotate. The first guide roller is linked with a second driving component for driving the first guide roller to rotate.

[0008] Using the above technical solution, the second driving component drives the first guide roller to rotate, conveying the double-sided adhesive (including release paper, fixed-length adhesive segments, and functional adhesive segments) cut by the adhesive surface separation component, so that it enters the separation area (between the first guide roller and the adhesive separation roller) with the adhesive surface facing the film material. The first driving component drives the adhesive separation roller to rotate, and its arc-shaped pressing part rotates with the adhesive separation roller. The arc-shaped pressing part and the first guide roller form a clamping space. The arc-shaped pressing part applies pressure through the arc-shaped contact surface, so that the fixed-length adhesive segment is in close contact with the film material. Since the adhesion force between the film material and the adhesive surface is greater than the adhesion force between the release paper and the adhesive surface, the fixed-length adhesive segment is adhered to the film material and detaches with the film material. Then, the release paper and functional adhesive segments continue to be conveyed with the first guide roller, completing the directional separation. The first and second drive components independently control their rotation speeds to match the film traction speed during the separation of the fixed-length adhesive segments and the continuous conveying speed of the functional adhesive segments, ensuring that only the cut fixed-length adhesive segments are separated and avoiding interference with the functional adhesive segments. Furthermore, the arc-shaped contact surface of the arc-shaped pressing part can apply concentrated and uniform pressure to the fixed-length adhesive segments, enhancing the adhesion between the film and the adhesive surface and ensuring that the fixed-length adhesive segments are completely transferred to the film.

[0009] The aforementioned degumming device can be further configured as follows: a first pressing member and a second pressing member are installed on the adhesive separation roller, arranged sequentially along the axis of the adhesive separation roller. The first pressing member has a first mounting hole sleeved on the adhesive separation roller and a first arc-shaped pressing part extending outward. The second pressing member has a second mounting hole sleeved on the adhesive separation roller and a second arc-shaped pressing part extending outward.

[0010] By adopting the above technical solution, a first pressing component and a second pressing component are set up. The axial adjustment function can flexibly adjust the distance between the two pressing components according to the width of the double-sided tape, ensuring that the pressing part covers the effective area of ​​the adhesive surface and avoiding incomplete separation of the edge of the wide adhesive surface or wasted pressure on the narrow adhesive surface. The circumferential adjustment function controls the contact time between the arc-shaped pressing part and the fixed-length adhesive surface segment by changing the phase difference of the pressing components, adapting to the separation requirements of fixed-length adhesive surface segments of different lengths. It can meet the production of multi-specification products without replacing the pressing components, and can cover the diverse adhesive surface separation requirements from narrow to wide and short to long segments, enhancing versatility.

[0011] The aforementioned degumming device can be further configured such that: both ends of the adhesive separation roller are rotatably connected to a first sliding block via bearings; the adhesive breaking frame is machined with a set of first strip holes corresponding to each set of first sliding blocks; each set of first sliding blocks is installed in a set of first strip holes; one end of the first strip hole is open; and a first stop block for sealing the opening of the first strip hole is detachably connected to the adhesive breaking frame.

[0012] Using the above technical solution, the first sliding block is loosened (e.g., by screws or pins), and then the first sliding block can slide along the first strip hole, causing the adhesive separation roller to move closer to or further away from the first guide roller, thereby adjusting the clamping gap between the two to accommodate double-sided adhesive or film materials of different thicknesses. This ensures that the pressure applied by the arc-shaped pressing part is always adapted to the material characteristics (e.g., increased pressure for thick adhesive surfaces and decreased pressure for thin adhesive surfaces), avoiding separation failure due to insufficient pressure or problems caused by excessive pressure. The first stop block can be detachably connected to the adhesive break bracket via screws. Furthermore, one end of the first strip hole is open; after removing the first stop block, the first sliding block along with the adhesive separation roller can be directly removed from the opening without disassembling other parts of the adhesive break bracket, facilitating the installation, replacement, or maintenance of the adhesive separation roller. The stop block ensures the installation stability of the first sliding block during operation, preventing accidental dislodgement.

[0013] The aforementioned degumming device can be further configured such that: the adhesive surface separation assembly includes a cutting support roller and a roller that are parallel to each other; the two ends of the cutting support roller are rotatably mounted on the adhesive breaking frame through bearings; the roller has a cutting edge machined on it for cutting off the continuous adhesive surface; the cutting support roller is linked with a second driving component; and the roller is linked with a third driving component for driving the roller to rotate.

[0014] Using the above technical solution, the adhesive surface separation component, through the cooperation of the cutting support roller and the roller cutter, can cut the adhesive surface of the double-sided adhesive according to a preset length, while keeping the release paper continuous and undamaged. This forms "fixed-length adhesive surface segments" and "functional adhesive surface segments," achieving functional zoning of the adhesive surface and meeting the dual requirements of "peeling start point" and "product bonding" in actual use. The cutting support roller is linked with the second drive component (synchronously conveying the double-sided adhesive), and the roller cutter is independently driven by the third drive component (controlling the cutting rhythm). By adjusting the speed or start / stop frequency of the third drive component, the cutting requirements of different "preset lengths of fixed-length adhesive surface segments" can be precisely matched, ensuring that the functional adhesive surface segments are always stably attached to the release paper. The size switching of fixed-length adhesive surface segments can be achieved without mechanical adjustment, adapting to the production of diverse product specifications.

[0015] The aforementioned degumming device can be further configured such that: both ends of the roller are rotatably connected to a second sliding block via bearings; the glue-breaking frame is machined with a set of second strip holes corresponding to each set of second sliding blocks; each set of second sliding blocks is installed in a set of second strip holes; one end of the second strip hole is open; and a second stop block for sealing the opening of the second strip hole is detachably connected to the glue-breaking frame.

[0016] Using the above technical solution, loosening the second sliding block (e.g., by screws or pins) allows it to slide along the second strip-shaped hole, moving the entire roller closer to or further away from the cutting support roller. This adjusts the cutting gap between the two, accommodating double-sided tape of different thicknesses or adhesive materials of different viscosities. This ensures the cutting edge accurately cuts the adhesive surface (without damaging the release paper) while avoiding scratches on the release paper due to an excessively small gap or incomplete cutting due to an excessively large gap. One end of the second strip-shaped hole is open. After removing the second stop, the second sliding block and roller can be directly removed from the opening without disassembling other parts of the adhesive cutter frame, facilitating the installation and replacement of the roller. The second stop is detachably connected to the adhesive cutter frame, sealing the opening of the strip-shaped hole during operation to prevent the second sliding block from dislodging due to vibration or external force, ensuring the positional stability of the roller during high-speed cutting.

[0017] The aforementioned degumming device can be further configured as follows: the second driving component includes a guide driven wheel linked with the first guide roller, a cutting support driven wheel linked with the cutting support roller, and a transmission wheel arranged between the guide driven wheel and the cutting support driven wheel. The cutting support driven wheel is engaged with a main driving wheel, and the main driving wheel is linked with a third servo motor. The third servo motor is mounted on the degumming frame.

[0018] Using the above technical solution, the third servo motor can synchronously drive the cutting support roller (for cutting the adhesive surface) and the first guide roller (for conveying after cutting) through gear meshing transmission of the main drive wheel, the cutting support driven wheel, the transmission wheel and the guide driven wheel, ensuring that the speed of the two is matched, avoiding wrinkles of the double-sided adhesive due to speed difference, and ensuring that the "fixed length adhesive surface segment" can accurately enter the adhesive surface separation component after cutting.

[0019] The aforementioned degumming device can be further configured as follows: the first driving component includes a glue-separating driven wheel linked to one end of the glue-separating roller and a glue-separating driving wheel meshing with the glue-separating driven wheel, the glue-separating driving wheel being linked to a first servo motor, the first servo motor being mounted on the glue-cutting frame; the third driving component includes a roller driven wheel linked to one end of the roller roller and a roller driving wheel meshing with the roller driven wheel, the roller driving wheel being linked to a second servo motor, the second servo motor being mounted on the glue-cutting frame.

[0020] Using the above technical solution, the first servo motor drives the adhesive separation roller through the adhesive separation drive wheel and driven wheel, and the second servo motor drives the roller cutter roller through the roller cutter drive wheel and driven wheel. Both are independently controlled and have high-precision speed adjustment capabilities, which can accurately adapt to the needs of adhesive separation (film traction) and adhesive cutting (fixed-length cutting). For example, the speed of the roller cutter roller can be adjusted according to the length of different "fixed-length adhesive segments" to control the cutting frequency, or the speed of the adhesive separation roller can be adapted to the film traction speed to ensure the continuity of separation and cutting actions.

[0021] The aforementioned degumming device can be further configured as follows: the adhesive layer feeding assembly includes an adhesive layer feeding roller, an adhesive layer winding roller, and a second guide roller rotatably mounted on the adhesive breaking frame. A tension adjustment mechanism is provided between the second guide roller and the adhesive layer feeding roller. The tension adjustment mechanism includes a third guide roller and a tension roller that are parallel to each other. The two ends of the tension roller are rotatably connected to third sliding blocks via bearings. The adhesive breaking frame is machined with a set of third strip holes corresponding to each set of third sliding blocks. Each set of third sliding blocks is installed in a set of third strip holes. One end of the third strip hole is open. A third stop block for sealing the opening of the third strip hole is detachably connected to the adhesive breaking frame. The second guide roller is distributed between the adhesive surface separation assembly and the adhesive surface separation assembly, and the second guide roller can pull the adhesive layer at the tension adjustment mechanism to the adhesive surface separation assembly.

[0022] The above technical solution utilizes a third sliding block (locked by screws or pins) that slides along the third slot, causing the tension roller to change position and adjust the film tension. This prevents wrinkles and ensures the film remains flat during transport, maintaining uniform pressure when in contact with the fixed-length adhesive section, thus improving adhesive adhesion stability. One end of the third slot is open and equipped with a detachable third stop, allowing the third sliding block and tension roller to be removed directly from the opening. This facilitates replacement, cleaning, and maintenance of the tension roller. The detachable stop also ensures the stability of the sliding block during operation, preventing the tension roller from dislodging due to vibration. The second guide roller, positioned between the adhesive separation assembly and the adhesive separation component, guides the tensioned film to the "clamping space between the first guide roller and the adhesive separation roller" of the adhesive separation component, ensuring the film contacts the adhesive side of the double-sided adhesive at a preset position, guaranteeing alignment between the fixed-length adhesive section and the film. The adhesive layer feeding roller (unwinding) and the adhesive layer take-up roller (rewinding the used film material) form a closed-loop conveying system, which, together with the guide roller and tension adjustment mechanism, enables continuous supply of film material and is compatible with the automated production process of the degumming device.

[0023] The aforementioned de-adhesion device can be further configured such that: the double-sided adhesive feeding assembly includes a double-sided adhesive feeding roller and a double-sided adhesive traction roller rotatably mounted on the adhesive breaking frame; the adhesive surface separating assembly is distributed between the double-sided adhesive feeding roller and the adhesive surface separating assembly; and the double-sided adhesive traction roller is distributed between the adhesive surface separating assembly and the double-sided adhesive feeding roller.

[0024] Using the above technical solution, the double-sided adhesive traction roller is distributed between the feeding roller and the adhesive surface partition component. Through traction, the double-sided adhesive is further tightened, eliminating tension fluctuations (such as slack and wrinkles) during the unwinding process of the roll material, and ensuring that the double-sided adhesive enters the adhesive surface partition component in a flat and stable manner.

[0025] The beneficial effects of this utility model are as follows: By cutting the adhesive surface separator into "fixed-length adhesive surface segments" and then peeling them off by the film material of the adhesive layer feeding component, the double-sided tape head forms a release paper area, which solves the problem of difficult peeling caused by the lack of a "peeling starting point" in the release paper of traditional double-sided tape. This realizes the automated cutting and de-adhesion of double-sided tape, greatly improving the convenience and efficiency of release paper separation when using products such as disposable medical sheets, and is especially suitable for scenarios with high requirements for operation speed, such as surgery.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 5 The de-adhesion device shown includes a de-adhesion frame a1, on which a double-sided adhesive feeding assembly, an adhesive surface separation assembly, an adhesive surface separation assembly, and an adhesive layer feeding assembly are mounted. The double-sided adhesive feeding assembly can transport double-sided adhesive to the adhesive surface separation assembly. The adhesive surface separation assembly can cut the adhesive surface of the double-sided adhesive and transport the cut double-sided adhesive to the adhesive surface separation assembly. The adhesive layer feeding assembly includes an adhesive layer feeding roller a2 and an adhesive layer winding roller a3 rotatably mounted on the de-adhesion frame a1. The adhesive layer feeding roller a2 can transport a film material with an "adhesive surface" to the adhesive surface separation assembly. When the double-sided adhesive with the cut adhesive surface is transported to the adhesive surface separation assembly, the adhesive surface of the double-sided adhesive faces the film material with an "adhesive surface". The adhesive surface separation assembly can adhere part of the cut adhesive surface to the film material with an "adhesive surface". The adhesive layer winding roller a3 can wind up the film material with the adhesive surface. The double-sided adhesive feeding assembly on the adhesive cutter a1 continuously transports the double-sided adhesive (including release paper and adhesive surface) to the adhesive surface separation assembly. The adhesive surface separation assembly cuts the adhesive surface of the double-sided adhesive (while keeping the release paper continuous), forming a "fixed-length adhesive surface segment" (the part to be separated) and a "functional adhesive surface segment" (retained on the release paper for subsequent bonding with disposable bed sheets and other products). The cut double-sided adhesive is then conveyed to the adhesive surface separation assembly. Simultaneously, the adhesive layer feeding assembly, via the adhesive layer feeding roller a2, feeds the adhesive surface separation assembly with an "adhesive-adhesive-compatible" film material (such as film, paper, etc., requiring only "adhesive surface"). (The adhesion between the film material and the adhesive surface must be stronger than that between the release paper and the adhesive surface.) When the double-sided adhesive enters the adhesive separation component, its adhesive surface faces the film material. The adhesive separation component ensures that the fixed-length adhesive section is in close contact with the film material. Utilizing the fact that the adhesion between the film material and the adhesive surface is greater than that between the release paper and the adhesive surface, the fixed-length adhesive section is adhered to the film material. Finally, the adhesive layer winding roller a3 winds up the film material with the adhesive surface, while the release paper and functional adhesive section continue to be conveyed, completing "partial adhesive peeling" to expose a portion of the release paper as the peeling starting point, thus achieving automated cutting and de-adhesion of the double-sided adhesive. In summary, after processing with this solution, the double-sided adhesive head becomes the release paper. In practical use (such as when medical staff lay out bed sheets), the release paper head can be directly grasped to quickly separate the release paper from the adhesive surface, reducing operation time. This is especially suitable for scenarios with high operational efficiency requirements, such as surgery.

[0031] The adhesive separation assembly includes a first guide roller a4 and an adhesive separation roller a5 that are parallel to each other. The two ends of the first guide roller a4 are rotatably mounted on the adhesive break frame a1 through bearings. At least one set of pressing parts are linked to the adhesive separation roller a5. The pressing parts are provided with arc-shaped pressing portions extending outward. The adhesive separation roller a5 is linked to a first driving component for driving the adhesive separation roller a5 to rotate. The first guide roller a4 is linked to a second driving component for driving the first guide roller a4 to rotate. The second drive component drives the first guide roller a4 to rotate, conveying the double-sided adhesive (including release paper, fixed-length adhesive segments, and functional adhesive segments) cut by the adhesive separation component, so that it enters the separation area (between the first guide roller a4 and the adhesive separation roller a5) with the adhesive surface facing the film material. The first drive component drives the adhesive separation roller a5 to rotate, and its arc-shaped pressing part rotates with the adhesive separation roller a5. The arc-shaped pressing part forms a clamping space with the first guide roller a4. The arc-shaped pressing part applies pressure through the arc-shaped contact surface, so that the fixed-length adhesive segment is in close contact with the film material. Since the adhesion force between the film material and the adhesive surface is greater than that between the release paper and the adhesive surface, the fixed-length adhesive segment is adhered to the film material and detaches with the film material. Then the release paper and functional adhesive segments continue to be conveyed with the first guide roller a4, completing the directional separation. The first and second drive components independently control their rotation speeds to match the film traction speed during the separation of the fixed-length adhesive segments and the continuous conveying speed of the functional adhesive segments, ensuring that only the cut fixed-length adhesive segments are separated and avoiding interference with the functional adhesive segments. Furthermore, the arc-shaped contact surface of the arc-shaped pressing part can apply concentrated and uniform pressure to the fixed-length adhesive segments, enhancing the adhesion between the film and the adhesive surface and ensuring that the fixed-length adhesive segments are completely transferred to the film.

[0032] The rubber separation roller a5 is equipped with a first pressing component a5-1 and a second pressing component a5-2 arranged sequentially along the axis of the rubber separation roller a5. The first pressing component a5-1 has a first mounting hole that is sleeved on the rubber separation roller a5. The first pressing component a5-1 has a first arc-shaped pressing part a5-3 extending outward. The second pressing component a5-2 has a second mounting hole that is sleeved on the rubber separation roller a5. The second pressing component a5-2 has a second arc-shaped pressing part a5-4 extending outward. The device is equipped with a first pressing component a5-1 and a second pressing component a5-2. The axial adjustment function allows for flexible adjustment of the distance between the two pressing components according to the width of the double-sided tape, ensuring that the pressing part covers the effective area of ​​the adhesive surface and avoiding incomplete separation of the edges of wide adhesive surfaces or wasted pressure on narrow adhesive surfaces. The circumferential adjustment function controls the contact time between the arc-shaped pressing part and the fixed-length adhesive surface segment by changing the phase difference of the pressing components, adapting to the separation requirements of fixed-length adhesive surface segments of different lengths. It can meet the production needs of multi-specification products without changing the pressing components, and can cover the diverse adhesive surface separation needs from narrow to wide and short to long segments, enhancing versatility.

[0033] Both ends of the rubber separation roller a5 are rotatably connected to a first sliding block a6 via bearings. The rubber break frame a1 is machined with a set of first strip holes a1-1 for each set of first sliding blocks a6. Each set of first sliding blocks a6 is installed in a set of first strip holes a1-1. One end of the first strip hole a1-1 is open. A first stop block a1-2 for sealing the opening of the first strip hole a1-1 is detachably connected to the rubber break frame a1. The first stop block a1-2 is detachably connected to the rubber break frame a1 via screws. Loosen the first sliding block a6 (e.g., by locking with a screw or pin), and then the first sliding block a6 can slide along the first strip hole a1-1, causing the adhesive separation roller a5 to move closer to or further away from the first guide roller a4, thereby adjusting the clamping gap between the two to accommodate double-sided adhesive or film materials of different thicknesses. This ensures that the pressure applied by the arc-shaped pressing part is always adapted to the material characteristics (e.g., increased pressure for thick adhesive surfaces and decreased pressure for thin adhesive surfaces), avoiding separation failure due to insufficient pressure or problems caused by excessive pressure. The first stop block a1-2 is detachably connected to the adhesive break frame a1 via screws, enabling quick assembly and disassembly of the first stop block a1-2. Furthermore, one end of the first strip hole a1-1 is open; after removing the first stop block a1-2, the first sliding block a6 along with the adhesive separation roller a5 can be directly removed from the opening without disassembling other parts of the adhesive break frame a1, facilitating the installation, replacement, or maintenance of the adhesive separation roller a5. The stop block ensures the installation stability of the first sliding block a6 during operation, preventing accidental dislodgement.

[0034] The adhesive surface separation assembly includes parallel cutting support rollers a7 and rollers a8. The two ends of the cutting support roller a7 are rotatably mounted on the adhesive cutter frame a1 via bearings. The rollers a8 are machined with cutting edges for cutting continuous adhesive surfaces. The cutting support roller a7 is linked to a second drive component, and the rollers a8 are linked to a third drive component for rotating the rollers a8. Through the cooperation of the cutting support rollers a7 and a rollers a8, the adhesive surface separation assembly can cut the adhesive surface of double-sided adhesive according to a preset length, while keeping the release paper continuous and undamaged. This forms "fixed-length adhesive surface segments" and "functional adhesive surface segments," achieving functional zoning of the adhesive surface and meeting the dual requirements of "peeling start point" and "product bonding" in actual use. The cutting support roller a7 is linked with the second drive component (synchronously conveying double-sided adhesive), while the roller roller a8 is driven independently by the third drive component (controlling the cutting rhythm). By adjusting the speed or start-stop frequency of the third drive component, the cutting requirements of different "predetermined lengths of fixed-length adhesive sections" can be precisely matched, ensuring that the functional adhesive sections are always stably attached to the release paper. The size switching of fixed-length adhesive sections can be achieved without mechanical adjustment, adapting to the production of diverse product specifications.

[0035] Both ends of the roller a8 are rotatably connected to second sliding blocks a9 via bearings. The glue-cutting frame a1 has a set of second strip holes a1-3 machined for each set of second sliding blocks a9. Each set of second sliding blocks a9 is installed within a set of second strip holes a1-3. One end of the second strip hole a1-3 is open. A second stop block a1-4 is detachably connected to the glue-cutting frame a1 to seal the opening at the second strip hole a1-3. The second stop block a1-4 is detachably connected to the glue-cutting frame a1 via screws. Loosening the second sliding block a9 (e.g., by locking with screws or pins) allows it to slide along the second strip hole a1-3, moving the roller a8 closer to or further away from the cutting support roller a7. This adjusts the cutting gap between the two, adapting to different thicknesses of double-sided tape or different adhesive materials, ensuring the cutting edge accurately cuts the adhesive surface (without damaging the release paper) while avoiding scratches on the release paper due to too small a gap or incomplete cutting due to too large a gap. The second strip-shaped hole a1-3 has an open end. After removing the second stop block a1-4, the second sliding block a9 along with the roller cutter a8 can be directly removed from the opening without disassembling other parts of the glue-cutting frame a1, facilitating the installation and replacement of the roller cutter a8. The second stop block a1-4 is detachably connected to the glue-cutting frame a1. During operation, it blocks the opening of the strip-shaped hole to prevent the second sliding block a9 from coming off due to vibration or external force, ensuring the positional stability of the roller cutter a8 during high-speed cutting.

[0036] The second driving component includes a guide driven wheel a10 linked to the first guide roller a4, a cutting support driven wheel a11 linked to the cutting support roller a7, and a transmission wheel a12 arranged between the guide driven wheel a10 and the cutting support driven wheel a11. The cutting support driven wheel a11 meshes with a main drive wheel a13, and the main drive wheel a13 is linked with a third servo motor a14, which is mounted on the glue-cutting frame a1. Through the gear meshing transmission of the main drive wheel a13, the cutting support driven wheel a11, the transmission wheel a12, and the guide driven wheel a10, the third servo motor a14 can synchronously drive the cutting support roller a7 (for glue surface cutting) and the first guide roller a4 (for post-cutting conveying), ensuring that their speeds are matched, avoiding wrinkles in the double-sided tape due to speed differences, and ensuring that the "fixed-length glue surface segment" can accurately enter the glue surface separation component after cutting.

[0037] The first driving component includes a glue-separating driven wheel a15 linked to one end of the glue-separating roller a5, and a glue-separating driving wheel a16 meshing with the glue-separating driven wheel a15. The glue-separating driving wheel a16 is linked to a first servo motor a25, which is mounted on the glue-cutting frame a1. The third driving component includes a cutter driven wheel a17 linked to one end of the cutter roller a8, and a cutter driving wheel a18 meshing with the cutter driven wheel a17. The cutter driving wheel a18 is linked to a second servo motor a19, which is mounted on the glue-cutting frame a1. The first servo motor a25 drives the adhesive separation roller a5 through the adhesive separation drive wheel a16 and the driven wheel, and the second servo motor a19 drives the cutter roller a8 through the cutter drive wheel a18 and the driven wheel. Both are independently controlled and have high-precision speed adjustment capabilities, which can accurately adapt to the needs of adhesive separation (film traction) and adhesive cutting (fixed-length cutting). For example, the speed of the cutter roller a8 can be adjusted according to the length of different "fixed-length adhesive segments" to control the cutting frequency, or the speed of the adhesive separation roller a5 can be adapted to the film traction speed to ensure the continuity of separation and cutting actions.

[0038] The adhesive layer feeding assembly also includes a second guide roller a20. A tension adjustment mechanism is provided between the second guide roller a20 and the adhesive layer feeding roller a2. The tension adjustment mechanism includes a third guide roller and a tension roller a21 that are parallel to each other. The two ends of the tension roller a21 are rotatably connected to a third sliding block a22 through bearings. The glue-breaking frame a1 is machined with a set of third strip holes a1-5 for each set of third sliding blocks a22. Each set of third sliding blocks a22 is installed in a set of third strip holes a1-5. One end of the third strip hole a1-5 is open. A third stop block a1-6 for sealing the opening of the third strip hole a1-5 is detachably connected to the glue-breaking frame a1. The third stop block a1-6 is detachably connected to the glue-breaking frame a1 through screws. The second guide roller a20 is distributed between the adhesive surface separation assembly and the adhesive surface separation assembly, and the second guide roller a20 can pull the adhesive layer at the tension adjustment mechanism to the adhesive surface separation assembly. By loosening the third sliding block a22 (e.g., by locking with a screw or pin) and sliding it along the third slot a1-5, the position of the tension roller a21 is changed to adjust the tension of the film material, avoiding wrinkles and ensuring that the film material remains flat during transportation. This ensures uniform pressure when in contact with the fixed-length adhesive section, improving the adhesion stability of the adhesive surface. One end of the third slot a1-5 is open and equipped with a detachable third stop a1-6, allowing the third sliding block a22 along with the tension roller a21 to be directly removed from the opening. This facilitates the replacement, cleaning, or maintenance of the tension roller a21. The detachable stop also ensures the installation stability of the sliding block during operation, preventing the tension roller a21 from dislodging due to vibration. The second guide roller a20 is located between the adhesive surface separation assembly and the adhesive surface separation assembly. It can guide the tension-adjusted film material to the "clamping space between the first guide roller a4 and the adhesive surface separation roller a5" of the adhesive surface separation assembly, ensuring that the film material and the adhesive surface side of the double-sided adhesive are in contact at a preset position, and ensuring the alignment of the fixed-length adhesive surface section with the film material. The adhesive layer feeding roller a2 (unwinding) and the adhesive layer take-up roller a3 (rewinding the used film material) form a closed-loop conveying system, which, together with the guide roller and the tension adjustment mechanism, realizes the continuous supply of film material and is compatible with the automated production process of the de-adhesive device.

[0039] The double-sided adhesive feeding assembly includes a double-sided adhesive feeding roller a23 and a double-sided adhesive traction roller a24 rotatably mounted on the adhesive breaker a1. An adhesive surface separation assembly is distributed between the double-sided adhesive feeding roller a23 and the adhesive surface separation assembly, and the double-sided adhesive traction roller a24 is distributed between the adhesive surface separation assembly and the double-sided adhesive feeding roller a23. The double-sided adhesive traction roller a24, distributed between the feeding roller and the adhesive surface separation assembly, further tensions the double-sided adhesive through traction, eliminating tension fluctuations (such as slack or wrinkles) during the unwinding process, ensuring that the double-sided adhesive enters the adhesive surface separation assembly in a flat and stable manner.

[0040] The working principle of this embodiment is as follows: Figure 1As shown, the double-sided adhesive feeding roller a23 of the double-sided adhesive feeding assembly releases the double-sided adhesive roll, which is then tensioned by the double-sided adhesive traction roller a24. The double-sided adhesive (including release paper and adhesive surface) is continuously transported to the adhesive surface separation assembly, ensuring that the double-sided adhesive enters the cutting area smoothly. The cutting support roller a7 of the adhesive surface separation assembly cooperates with the roller a8. The cutting edge on the roller a8 rotates under the drive of the third drive component (second servo motor a19, roller drive wheel a18, roller driven wheel a17), cutting the adhesive surface of the double-sided adhesive (while the release paper remains continuous), forming a "fixed-length adhesive surface segment" (the part to be separated) and a "functional adhesive surface segment" (retained on the release paper). The cut double-sided adhesive is then conveyed to the adhesive surface separation assembly. Simultaneously, the adhesive layer feeding roller a2 of the adhesive layer feeding assembly releases the film material with an "adhesive surface," which is then pulled to the adhesive surface separation assembly by the second guide roller a20 via the tension adjustment mechanism, ensuring that the film material is flat and aligned with the adhesive side of the double-sided adhesive. The first guide roller a4 (driven by the second drive component) of the adhesive surface separation assembly conveys the cut double-sided adhesive, with its adhesive surface facing the film material; the adhesive surface separation roller a5 (driven by the first drive component) drives the first pressing component a5-1 and the second pressing component a5-2 to rotate, and their arc-shaped pressing parts form a clamping space with the first guide roller a4, applying pressure to the fixed-length adhesive surface segment, making the adhesive surface and the film material in close contact; taking advantage of the fact that the adhesion force between the film material and the adhesive surface is greater than the adhesion force between the release paper and the adhesive surface, the fixed-length adhesive surface segment is adhered to the film material. The film material with a fixed length of adhesive surface is wound up by the adhesive layer winding roller a3; the release paper and functional adhesive surface are continued to be conveyed by the first guide roller a4 to complete the "partial adhesive surface peeling", which finally makes the head of the double-sided tape form a structure with only release paper, making it easy to tear the double-sided tape.
