Description

Technical Field

[0001] The invention relates to the technical field of self-adhesive tapes, in particular to a self-adhesive tape rolling device. Background Art

[0002] In the traditional roll production of self-adhesive tape, there are common key issues that restrict continuous automated production. Replacing the material roll and peeling off the release film are mainly completed manually. When a large roll of self-adhesive tape is exhausted, the machine needs to be stopped, and the operator must manually remove the empty barrel, install a new roll, and align the end of the old and new self-adhesive tapes with the starting end to stick them together. Existing production lines are not only time-consuming, causing frequent interruptions and reducing production efficiency, but also the peeling of the release film from the surface of the self-adhesive tape is also done entirely manually by the operator, at a speed that is difficult to match the conveyor line speed and is labor-intensive. These links are highly dependent on manual labor and require shutdowns for roll-changing operations, making it difficult for existing production lines to achieve efficient and continuous operation, resulting in high labor costs and limited production capacity. Summary of the Invention

[0022] Reference Figures 1 to 12As shown, a self-adhesive tape reeling device according to one embodiment of the present invention includes: a mounting wall 1000, an automatic reeling mechanism 2000, a conveying mechanism 4000, a pressure roller 5000, a reeling mechanism 6000, a redirecting roller 7000, and a slitting mechanism. The mounting wall 1000 is welded from steel plates and steel sections. The mounting wall 1000 provides a mounting surface for other components. The mounting wall 1000 is vertically disposed. The automatic reeling mechanism 2000 is connected to the mounting wall 1000. The self-adhesive tape 3100 is wound around a barrel 3000. The specific structures of the self-adhesive tape 3100 and the barrel 3000 are prior art and will not be described in detail. The automatic rewinding mechanism 2000 is used to load the self-adhesive tape 3100 wound around the barrel 3000 and to connect another roll of self-adhesive tape 3100 when one roll is exhausted. The automatic rewinding mechanism 2000 continuously delivers the self-adhesive tape 3100 to the conveyor mechanism 4000, where it is then transported to the next process step, improving production efficiency. The conveyor mechanism 4000 horizontally transports the self-adhesive tape 3100 from the automatic rewinding mechanism 2000. The conveyor mechanism 4000 utilizes a conventional conveyor belt, with the conveying direction of the conveyor mechanism 4000 running from front to back. The self-adhesive tape 3100 extends parallel to the conveying direction of the conveyor mechanism 4000. A film 3110 to be peeled off is attached to the upper end of the self-adhesive tape 3100. The film 3110 must be separated from the self-adhesive tape 3100 before it can enter the slitting mechanism. The installation method and specific structure of the pressure roller 5000 are prior art and will not be described in detail. The pressure roller 5000 is rotatably mounted on the mounting wall 1000 and is used to push the self-adhesive tape 3100 against the conveyor mechanism 4000. This close contact between the self-adhesive tape 3100 and the conveyor mechanism 4000 increases friction, enabling the conveyor mechanism 4000 to stably transport the self-adhesive tape 3100. The reeling mechanism 6000 is located above the conveyor mechanism 4000 and is used to peel the film 3110 from the self-adhesive tape 3100. This automatically peels the film 3110 from the self-adhesive tape 3100, reducing operator workload. A redirecting roller 7000 is located between the conveyor mechanism 4000 and the automatic reeling mechanism 2000 and is used to change the direction of movement of the self-adhesive tape 3100. There can be one or more redirecting rollers 7000, and their implementation is conventional and will not be described in detail. A slitting mechanism is located at the end of the conveying mechanism 4000 and is used to cut the self-adhesive tape 3100. After the self-adhesive tape 3100 is separated from the film 3110, the self-adhesive tape 3100 is fed into the slitting mechanism. The slitting mechanism cuts the self-adhesive tape 3100. The slitting mechanism is conventional and will not be described in detail, nor is it shown in the figure.The automatic rewinding mechanism 2000 automatically rewinds the next roll of self-adhesive tape 3100 after each roll is exhausted, ensuring continuous delivery of the tape 3100 to the conveyor mechanism 4000. The pressure roller 5000 ensures that the tape 3100 adheres tightly to the conveyor mechanism 4000, effectively increasing friction between the two and preventing the tape 3100 from slipping or deviating during transport. The rewinding mechanism 6000 automatically peels the film 3110 from the tape 3100, eliminating manual peeling and enabling continuous production and improving efficiency.

[0023] Reference Figure 1 、 Figure 2 and Figure 8As shown, it is understood that the automatic rewinding mechanism 2000 includes a rotating disk 2100, a first clamping mechanism 2200, and a second clamping mechanism 2300. The rotating disk 2100 is rotatably mounted on the mounting wall 1000, with its rotation axis perpendicular to the mounting wall 1000. A switching motor 1100 is mounted on the mounting wall 1000 and is connected to the rotating disk 2100 via a gear train. The gear train amplifies the output torque of the switching motor 1100. The switching motor 1100 drives the rotating disk 2100 to rotate. A stepper motor is used for precisely controlling the rotation angle of the rotating disk 2100. The rotating disk 2100 has a first position and a second position. The switching motor 1100 can drive the rotating disk 2100 to switch between the first position and the second position, rotating the rotating disk 2100 from the first position to the second position. The first clamping mechanism 2200 and the second clamping mechanism 2300 have the same structure. The first clamping mechanism 2200 is rotatably mounted on the rotating disk 2100 and is used to secure the self-adhesive tape 3100 and the barrel 3000. The second clamping mechanism 2300 is rotatably mounted on the rotating disk 2100 and is used to secure the self-adhesive tape 3100 and the barrel 3000. The first clamping mechanism 2200 is used to secure the self-adhesive tape 3100 and the barrel 3000. After being secured to the first clamping mechanism 2200, the barrel 3000 can rotate but cannot move axially along the barrel 3000. The second clamping mechanism 2300 is rotatably mounted on the rotating disk 2100 and is used to secure the self-adhesive tape 3100 and the barrel 3000. After being secured to the second clamping mechanism 2300, the barrel 3000 can rotate but cannot move axially along the barrel 3000. The rotational axes of the second clamping mechanism 2300, the first clamping mechanism 2200, and the rotating disk 2100 are parallel to each other. When the rotating disk 2100 is in the first position, the first clamping mechanism 2200 is located between the second clamping mechanism 2300 and the redirecting roller 7000. When the rotating disk 2100 is in the second position, the second clamping mechanism 2300 is located between the first clamping mechanism 2200 and the redirecting roller 7000. When the rotating disk 2100 is in the first position, the barrel 3000 is fixed on the first clamping mechanism 2200. The pulling mechanism drives the self-adhesive tape 3100 wound on the barrel 3000 through the redirecting roller 7000 and then transported to the next process.When the self-adhesive tape 3100 wound on the barrel 3000 is about to be used up, the rotating disk 2100 is first switched to the second position, and then the operator installs the fully rolled self-adhesive tape 3100 on the second clamping mechanism 2300. Since the second clamping mechanism 2300 is located between the first clamping mechanism 2200 and the redirecting roller 7000 when the rotating disk 2100 is in the second position, after the self-adhesive tape 3100 on the first clamping mechanism 2200 is used up, the end of the self-adhesive tape 3100 will pass through the second clamping mechanism 2300. At this time, the operator sticks the starting end of the self-adhesive tape 3100 on the second clamping mechanism 2300 and the end of the self-adhesive tape 3100 driven by the pulling mechanism to each other, and the pulling mechanism will drive the fully rolled self-adhesive tape 3100 on the second clamping mechanism 2300 to continue to be transported to the next process. When the self-adhesive tape 3100 on the second clamping mechanism 2300 is almost exhausted, rotating disk 2100 is switched to the first position, the operating personnel installs the self-adhesive tape 3100 of full roll on the first clamping mechanism 2200 then, because when rotating disk 2100 was positioned at the first position, the first clamping mechanism 2200 was positioned between the second clamping mechanism 2300 and the redirecting roller 7000, so after the self-adhesive tape 3100 on the second clamping mechanism 2300 was exhausted, the end of self-adhesive tape 3100 will pass through the first clamping mechanism 2200, at this moment, the operating personnel drives the end of self-adhesive tape 3100 to be pasted mutually with the self-adhesive tape 3100 starting end on the first clamping mechanism 2200 and the pulled mechanism, and the pulling mechanism will drive the self-adhesive tape 3100 of full roll on the first clamping mechanism 2200 to continue to be transported to next process.Repeat above steps and can automatically bond self-adhesive tape 3100, make self-adhesive tape 3100 can be transported to next process continuously. The main task of the operator is only to install the full roll drum 3000 on the spare clamping mechanism and to perform the pasting operation when the ends of the new and old self-adhesive tapes 3100 meet.

[0024] Reference Figures 8 to 12As shown, it is understood that the first clamping mechanism 2200 includes a first rotating roller 2210, a mounting post 2220, and three clamping plates 2230. The first rotating roller 2210 is rotatably mounted on the rotating disk 2100. The connection method between the first rotating roller 2210 and the mounting wall 1000 is conventional and will not be described in detail. The first rotating roller 2210 is perpendicular to the mounting wall 1000. The mounting post 2220 is bolted to the first rotating roller 2210 and is sleeved on the first rotating roller 2210. The diameter of the mounting post 2220 is larger than the diameter of the first rotating roller 2210. The card plate 2230 is slidably connected to the mounting column 2220. The three card plates 2230 are symmetrically arranged with the rotation axis of the first rotating roller 2210 as the center. The first rotating roller 2210 extends horizontally in the direction away from the mounting wall 1000. The card plate 2230 can slide radially along the mounting column 2220. The card plate 2230 can move to a preset position. The preset position is within the sliding stroke of the card plate 2230. The mounting column 2220 provides an installation position for the card plate 2230. When the card plate 2230 is at the preset position, the side of the card plate 2230 away from the mounting column 2220 is against the inner wall of the barrel 3000. A limiting member 2221 is connected to the mounting column 2220, and the limiting member 2221 is used to prevent the card plate 2230 from detaching from the mounting column 2220. The mounting column 2220 is connected to an elastic member 2222, and three elastic members 2222 are correspondingly arranged. The elastic member 2222 is connected to the mounting column 2220, and the elastic member 2222 is used to drive the card plate 2230 to move away from the mounting column 2220 and drive the card plate 2230 to press tightly against the inner wall of the barrel 3000. When the barrel 3000 is not installed, the card plate 2230 is pushed by the elastic member 2222 to a position away from the mounting post 2220, and the limit member 2221 limits the travel of the card plate 2230 away from the mounting post 2220. When the barrel 3000 is installed, the card plate 2230 is pushed manually by the barrel 3000 or the operator to compress the elastic member 2222 and approach the mounting post 2220, automatically adapting to the inner diameter of the barrel 3000. After the barrel 3000 is installed in place, the elastic member 2222 drives the card plate 2230 to press against the inner wall of the barrel 3000, forcing the barrel 3000 to automatically position on the central axis of the first rotating roller 2210, and the friction between the card plate 2230 and the barrel 3000 is used to fix the barrel 3000. To install the barrel 3000, simply push it in. The retaining plate 2230 automatically moves inward upon contact with the inner wall of the barrel 3000, eliminating the need for complicated operations or additional tools. To remove the barrel 3000, simply pull it outward, overcoming the elastic force and friction of the elastic member 2222. The retaining plate 2230 then slides inward along the inner wall of the barrel 3000. This reduces the time required to replace the barrel 3000 and improves production efficiency.

[0025] Reference Figures 8 to 12As shown, it is understood that three symmetrical slots 2223 are provided on the outer circumferential wall of the mounting post 2220. The slots 2223 extend axially along the mounting post 2220, providing radial movement limits for the intermediate plate 2231 and slider 2232. Pushed by the elastic member 2222 or squeezed by the barrel 3000, the clamping plate 2230 can only move radially along the mounting post 2220. An intermediate plate 2231 is provided on the side of the clamping plate 2230 near the mounting post 2220, extending into the corresponding slots 2223. A slider 2232 is provided on the end of the intermediate plate 2231 away from the clamping plate 2230, with a limiter 2221 disposed within the slots 2223. The intermediate plate 2231 is smaller than the slider 2232, and the limiter 2221 narrows the opening of the slot 2223. The opening of the chute 2223 only allows the middle plate 2231 to pass through, and cannot allow the middle plate 2231 to pass through, so the limiter 2221 can play a role in limiting the travel of the slider 2232. The limiter 2221 is integrally formed with the mounting post 2220. The limiter 2221 is set at the opening of the chute 2223 to form a T-shaped cross-section of the chute 2223. The travel of the slider 2232 is limited by the bottom of the chute 2223 and the limiter 2221. The limiter 2221 limits the maximum extension position of the card plate 2230 when the barrel 3000 is not installed, and the bottom of the chute 2223 limits the maximum retraction position of the card plate 2230 when the barrel 3000 is installed. The slider 2232, the middle plate 2231 and the limiter 2221 are embedded in the chute 2223 without adding any extra outer diameter to the mounting post 2220, resulting in a compact structure.

[0026] Reference Figures 8 to 12 As shown, it can be understood that a set screw 2224 is provided through the side wall of the slide groove 2223. The set screw 2224 is a hexagon socket set screw. The set screw 2224 passes through the side wall of the slide groove 2223 and extends into the slide groove 2223. The set screw 2224 limits the position of the slider 2232 in a direction parallel to the axis of the mounting post 2220. The installation steps of the clamping plate 2230 are as follows: tighten the set screw 2224 until it is removed from the slide groove 2223, slide the intermediate plate 2231 and the slider 2232 into the slide groove 2223 along the length direction of the slide groove 2223, and then tighten the set screw 2224 into the slide groove 2223 so that the set screw 2224 blocks the slider 2232. During disassembly, one only needs to loosen the set screw 2224 with an Allen wrench to release the axial constraint of the slider 2232, and then the entire assembly consisting of the clamping plate 2230, the intermediate plate 2231, and the slider 2232 can be pulled out axially along the slide groove 2223. It is foreseeable that the extension direction of the set screw 2224 avoids the clamping plate 2230 so that the clamping plate 2230 will not block the wrench when it is used.

[0027] Reference Figures 8 to 12As shown, it can be understood that the elastic member 2222 is a spring sheet, and the elastic member 2222 is bolted to the bottom wall of the slide 2223. As a flat elastic element, the spring sheet can be easily embedded in the narrow space at the bottom of the slide 2223. Compared with the coil spring, it can save radial space and the overall structure is compact. The spring sheet deforms evenly when subjected to pressure, preventing the card plate 2230 from getting stuck due to uneven force. When the elastic member 2222 needs to be replaced, the card plate 2230 is first removed, and then the bolts fixing the elastic member 2222 are loosened through the opening of the slide 2223 to remove the elastic member 2222. The elastic member 2222 and the slider 2232 are pressed against each other to indirectly push the card plate 2230.

[0028] Reference Figures 1 to 7As shown, it can be understood that the reeling mechanism 6000 includes a reeling shaft 6100 and a detection mechanism 6200. The mounting wall 1000 is connected to a reeling drive mechanism 1200. The reeling shaft 6100 is rotatably mounted on the mounting wall 1000. The reeling shaft 6100 is horizontally disposed, and the extension direction of the reeling shaft 6100 is perpendicular to the extension direction of the self-adhesive tape 3100. The reeling shaft 6100 is connected to the output shaft of the reeling drive mechanism 1200 via a coupling. The reeling drive mechanism 1200 can drive the reeling shaft 6100 to rotate. The reeling shaft 6100 is detachably connected to a material tray 6110, and the reeling drive mechanism 1200 drives the material tray 6110 to rotate via the reeling shaft 6100. The self-adhesive tape 3100 on the conveyor mechanism 4000 passes beneath the material tray 6110. As the material tray 6110 rotates with the reel 6100, it winds up the film 3110 attached to the self-adhesive tape 3100. To use the self-adhesive tape 3100, one simply peels off the starting end of the film 3110 and attaches it to the material tray 6110. The material tray 6110 rotates, winding and continuously peeling the film 3110 from the self-adhesive tape 3100. If the material tray 6110 rotates too quickly, the separation point between the film 3110 and the self-adhesive tape 3100 will move in the opposite direction of the tape's movement. If the material tray 6110 rotates too slowly, the separation point between the film 3110 and the self-adhesive tape 3100 will move in the direction of the tape's movement. Therefore, the rotation speed of the material tray 6110 needs to be controlled within an appropriate range. The detection mechanism 6200 is used to detect the position of the film 3110 after separation from the self-adhesive tape 3100 and adjust the rotation speed of the winding drive mechanism 1200 based on the position of the film 3110 after separation from the self-adhesive tape 3100. By adjusting the rotation speed of the winding drive mechanism 1200, the separation point of the film 3110 and the self-adhesive tape 3100 is kept within a predetermined range, allowing the material tray 6110 to properly wind the film 3110. As the material disc 6110 is being wound, the film 3110 is gradually wound around the material disc 6110, and the winding diameter becomes larger and larger. If the rotation speed of the material disc 6110 is constant, the speed of the wound film 3110 will continue to increase, which will cause the film 3110 to be pulled apart by mistake. Therefore, a constant rotation speed of the material disc 6110 cannot be used. Instead, the position of the peeled film 3110 must be detected by the detection mechanism 6200, and the rotation speed of the material disc 6110 must be fed back and adjusted in real time based on the measurement results, so that the separation point between the film 3110 and the self-adhesive tape 3100 is shifted back and maintained within a preset range. Reference Figures 1 to 7As shown, it can be understood that the end of the reel 6100 away from the reel drive mechanism 1200 is provided with a thread, and a nut 6120 is bolted to the reel 6100. An annular boss 6130 is connected to the reel 6100. One side of the material tray 6110 abuts against the annular boss 6130, and the other side abuts against the nut 6120. When replacing the material tray 6110, first loosen the nut 6120, then remove the old material tray 6110, install the new material tray 6110, and tighten the nut 6120. The material tray 6110 is clamped by the nut 6120 and the annular boss 6130. The use of the nut 6120 for fastening can compensate for the thickness differences of the material tray 6110, adapting to the material tray 6110 of various thicknesses.

[0029] Reference Figures 1 to 7 As shown, it is understood that the detection mechanism 6200 is connected to a controller, the winding drive mechanism 1200 is a stepper motor, and the controller is an RS485 stepper motor driver commonly used to control stepper motors. The controller controls the speed of the winding drive mechanism 1200 based on the measurement results of the detection mechanism 6200.

[0030] Reference Figures 1 to 7 As shown, it can be understood that the detection mechanism 6200 includes a rotating rod 6210 and two contact switches 6220. The contact switches 6220 are bolted to the mounting wall 1000. The contact switches 6220 are provided with strip slots for the bolts to pass through, facilitating fine-tuning of the mounting position of the contact switches 6220. The contact switches 6220 are electrically connected to the controller. The rotating rod 6210 is vertically mounted, with its lower end rotatably mounted on the mounting wall 1000. A vertical sleeve is welded to one side of the mounting wall 1000, and the lower end of the rotating rod 6210 extends into the sleeve. A detection ring 6211 is provided at the top of the rotating rod 6210. The film 3110 passes through the detection ring 6211. Changes in the position and tilt angle of the film 3110 drive the rotating rod 6210 to rotate via the detection ring 6211. Also provided at the top of the rotating rod 6210 is a paddle 6212, located between two contact switches 6220. As the rotating rod 6210 rotates, the paddle 6212 engages the two contact switches 6220. This purely mechanical measurement structure ensures stable and reliable operation, and is not susceptible to interference from external factors such as ambient light, dust, and moisture. As anticipated, the two contact switches 6220 are mounted independently, allowing the contact switches 6220 to be moved directly to adjust the preset separation range between the film 3110 and the self-adhesive tape 3100. The two contact switches 6220 are respectively set to the separation point moving forward too far and the separation point moving backward too far. The position offset of the film 3110 drives the rotating rod 6210 to rotate, causing the paddle 6212 to trigger the corresponding contact switch 6220, and the controller immediately executes the instruction to increase or decrease the speed of the winding drive mechanism 1200.

[0031] Usage steps: Place the rotating disk 2100 in the first position. The operator pushes the barrel 3000 with the fully rolled self-adhesive tape 3100 into the first clamping mechanism 2200. The clamping plate 2230 automatically tightens and clamps the inner wall of the barrel 3000 under the action of the elastic member 2222. Manually pull the starting end of the self-adhesive tape 3100 around the redirecting roller 7000 and manually pull the starting end of the self-adhesive tape 3100 to the pressing roller 5000, so that the pressing roller 5000 and the conveying mechanism 4000 clamp the self-adhesive tape 3100. Start the conveying mechanism 4000, and the conveying mechanism 4000 drives the self-adhesive tape 3100. When the starting end of the self-adhesive tape 3100 passes below the winding mechanism 6000 in horizontal backward motion, the conveyor belt is stopped. The operator then lifts the film 3110 from the self-adhesive tape 3100, passes the film 3110 upward through the detection ring 6211, and secures the end of the film 3110 to the material tray 6110. The operator then activates the winding drive mechanism 1200 and the conveyor mechanism 4000. The conveyor mechanism 4000 continues to drive the self-adhesive tape 3100 in horizontal backward motion, while the material tray 6110 of the winding mechanism 6000 continuously rotates, peeling the film 3110 from the self-adhesive tape 3100 and winding it. A mechanical feedback system consisting of the rotating rod 6210, the detection ring 6211, the paddle 6212, and the contact switch 6220 detects in real time whether the separation point between the film 3110 and the self-adhesive tape 3100 exceeds a preset range. The controller adjusts the speed of the winding drive mechanism 1200 in real time according to the trigger signal of the contact switch 6220 to keep the separation point between the film 3110 and the self-adhesive tape 3100 stable. The self-adhesive tape 3100 peeled off the film 3110 is transported to the slitting mechanism and cut according to the set requirements. When the self-adhesive tape 3100 wound on the barrel 3000 is about to be used up, the switching motor 1100 is started, and the switching motor 1100 drives the rotating disk 2100 to rotate 180 degrees to switch to the second position. Then the operator installs the barrel 3000 with a full roll of self-adhesive tape 3100 on the second clamping mechanism 2300. Since when the rotating disk 2100 is in the second position, the second clamping mechanism 2300 is located between the first clamping mechanism 2200 and the redirecting roller 7000. Therefore, after the self-adhesive tape 3100 on the first clamping mechanism 2200 is used up, the end of the self-adhesive tape 3100 will pass through the second clamping mechanism 2300. At this time, the operator sticks the starting end of the self-adhesive tape 3100 on the second clamping mechanism 2300 and the end of the self-adhesive tape 3100 driven by the pulled mechanism to each other, and the conveying mechanism 4000 continues to operate, pulling the self-adhesive tape 3100 on the new roll to achieve continuous feeding. When the roll on the second clamping mechanism 2300 is about to run out, the operator installs a new full roll barrel 3000 on the spare first clamping mechanism 2200. The operator then starts the switching motor 1100, which drives the rotating disk 2100 to rotate 180 degrees, and the rotating disk 2100 switches from the second position to the first position.At this point, the end of the old film roll on the second clamping mechanism 2300 is pulled near the first clamping mechanism 2200. The operator then affixes the starting end of the new film roll on the first clamping mechanism 2200 to the end of the old film roll. The conveyor mechanism 4000 continues operating during this process, and the new film roll is put into operation. When the film 3110 on the material tray 6110 is full, the rewinding drive mechanism 1200 is stopped. The nut 6120 at the end of the rewinding shaft 6100 is then loosened, cutting the film 3110. The operator then removes the full film 3110 material tray 6110 and replaces it with a new, empty one. The operator then tightens the nut 6120, which clamps the new material tray 6110, securing the starting end of the stripped film 3110 to the new tray 6110. The rewinding motor is then restarted.
