Description

Technical Field

[0001] This invention relates to the field of tape production technology, specifically to a conveying device used in tape processing and production. Background Technology

[0002] The production process of adhesive tape typically includes multiple steps such as substrate preparation, coating, drying, winding, slitting, rewinding, and packaging. Specifically, the production process of adhesive tape is as follows: First, the substrate (such as BOPP film) is unwound from the unwinding device. The pressure-sensitive adhesive is evenly coated onto the surface of the substrate by the coating machine. The coated substrate enters a drying oven channel that is tens of meters long and is dried and cured at a controlled temperature to set the adhesive layer. The dried tape master roll is wound into a wide roll by the winding device, i.e., the master roll. Then, the master roll is conveyed to the slitting machine, where it is longitudinally cut into several narrow strips by the slitting blade group and rewound into several medium-width transition rolls (commonly known as large rolls). These transition rolls are then conveyed to the rewinding machine and rewound into finished small rolls. Finally, the finished product is prepared through the packaging process.

[0003] In the aforementioned tape production process, rewinding is a crucial step in processing the transition roll (large reel) into finished small rolls. Rewinding conveyors are commonly used as the core equipment. The basic structure of existing rewinding conveyors includes a machine body, a release roller, a take-up roller, a guide roller, and an anti-stick roller mounted on the machine body. The workflow is as follows: The operator first manually places the inner tube of the tape (paper tube or plastic tube) onto the take-up roller. Then, the transition roll (large reel) is placed on the release roller. The end of the tape is pulled through the guide roller and anti-stick roller and wound onto the surface of the inner tube. The equipment is then started for rewinding. After rewinding, the tape is cut, and the finished small roll is removed from the take-up roller. A new inner tube is then placed on the tape, and the next roll is rewound.

[0004] However, existing small rewinding conveyors have the following technical defects in actual use: After each rewinding, the operator needs to complete three actions: unloading the finished roll, installing the new inner tube of the tape, and rewinding and fixing the end of the tape. During this process, the operator needs to release a section of tape from the transition roll to wrap the surface of the new inner tube of the tape. When releasing, a certain amount of tension needs to be applied to overcome the resistance of the correction roller and the anti-sticking roller, which is quite laborious. More importantly, during the process of pulling the tape, the operator is also prone to the problem of the tape sticking to their hands or the tape sticking itself, which affects the smoothness of the operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a conveying device for tape processing and production, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for tape processing and production, comprising a rewinding conveyor body and a take-up roller.

A stepper motor is installed within the rewinding conveyor body, and a connecting member is provided between the stepper motor and the telescopic pushing member.

[0007] Preferably, it also includes a release roller rotatably mounted on the rewinding conveyor body, and a correction roller and an anti-sticking roller fixedly mounted on the rewinding conveyor body.

[0008] Preferably, the cutting clamp includes a slide rod slidably connected to the slide opening. An mounting plate is fixedly installed at one end of the slide rod outside the rewinding conveyor body. An arc-shaped pressure plate and a cutter are installed on one side of the mounting plate. The arc-shaped pressure plate is used to squeeze the tape to fit tightly against the inner cylinder of the new tape. The cutter is used to cut the tape to facilitate its winding with the inner cylinder of the new tape. Stop bars matching the cutter are fixedly installed at equal intervals around the toothed disc.

[0009] Preferably, the rotating component includes a power motor fixedly installed inside the rewinding conveyor body, a half gear meshing with a gear plate is fixedly installed at the output end of the power motor, a fixed column is fixedly installed on one side of the half gear, an I-shaped frame is slidably arranged on the inner wall of the rewinding conveyor body, and the sliding rod and the fixed column are both slidably connected to the I-shaped frame.

[0010] Preferably, the telescopic fixing member includes multiple placement openings on the periphery of the take-up roller, a fixing plate is slidably disposed in the placement opening, a spring telescopic member is fixedly installed between the fixing plate and the take-up roller, the fixing plate is arc-shaped on the outer side of the take-up roller, and the fixing plate is obliquely shaped on the inner side of the take-up roller.

[0011] Preferably, the telescopic pusher includes a rectangular rod slidably connected to the rectangular groove. A plurality of inclined top blocks matching the inclined opening are fixedly installed at one end of the rectangular rod inside the rectangular groove for pushing the fixing plate against the inner cylinder of the tape. A T-shaped rod is fixedly installed at one end of the rectangular rod outside the rectangular groove, and a return spring is fixedly installed between the T-shaped rod and the take-up roller.

[0012] Preferably, the push ring has an opening on one side, the opening is arc-shaped, the contact surface between the T-shaped rod and the opening is also arc-shaped, the push ring has a through-hole annular sliding opening on one side, and the take-up roller is rotatably connected to the gear disc through a one-way bearing.

[0013] Preferably, the connector includes a rotating rod fixedly connected to the output end of the stepper motor, the rotating rod being rotatably connected to the push ring, the rotating rod being located within an annular sliding opening, a rectangular opening being provided at the outer end of the rotating rod, a rectangular sliding groove being provided at the outer end of the T-shaped rod, an arc-shaped block being slidably disposed within the rectangular sliding groove, a connecting spring being fixedly installed between the arc-shaped block and the rectangular sliding groove, the arc-shaped block being arched at one end within the rectangular opening, and having flat sides that slide in contact with the inner wall of the rectangular opening.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. To achieve rapid roll changing and automatic adhesion between the new tape inner tube and the tape end during rewinding, this invention rotates multiple take-up rollers at equal intervals on one side of a toothed disc. When the tape inner tube on one of the take-up rollers finishes winding, the toothed disc rotates at a predetermined angle to automatically switch the take-up rollers (moving the take-up roller with the new tape inner tube to the winding station, while simultaneously moving the finished take-up roller to one side). This facilitates subsequent removal of the finished tape roll and replacement of the new tape inner tube, and the roll changing and winding operations are mutually independent. (Without interference) During each switching of the take-up rollers, the unwound tape will naturally come into contact with the surface of the inner drum of the tape at the new station, achieving automatic adhesion by utilizing the tape's own adhesiveness. Subsequently, the cutting clamp is activated to cut the tape. Through the multi-station toothed disc switching mechanism, multiple take-up rollers can enter the take-up station in a cyclical alternation. During the switching process, the tape end and the inner drum of the new tape are simultaneously contacted and adhered, realizing the sequential linkage of "adhesion upon switching and separation upon cutting". This structure eliminates the need for repeated manual traction and winding operations after each drum change.

[0015] 2. To ensure a tight bond between the tape end and the new tape inner cylinder during tape cutting, preventing tape loosening during startup due to weak contact, this invention includes an arc-shaped pressure plate and a cutter on a mounting plate on one side of the slide bar. The mounting plate is connected to both the arc-shaped pressure plate and the cutter via a telescopic rod. After the gear plate switches positions, the mounting plate moves towards the new tape inner cylinder, causing the cutter to contact the stop bar and cut the already wound tape. Immediately afterward, the arc-shaped pressure plate moves to contact the new tape inner cylinder, applying pressure to the tape end. Apply a preset pressure to ensure tight adhesion between the tape and the inner tube surface. After the take-up roller starts rotating for rewinding, the arc-shaped pressure plate can continue to press for a certain period of time under the drive of the telescopic rod before retracting and resetting. The inner arc surface of the arc-shaped pressure plate matches the outer arc surface of the new inner tube of tape, resulting in a large contact area and better pressing effect compared to a flat pressure plate. This combines the cutting and pressing actions into one, achieving a "cutting and pressing" time-series linkage, ensuring that the tape end is firmly adhered to the inner tube of tape before rewinding begins.

[0016] 3. To simultaneously achieve automatic fixing of the inner tape cylinder and automatic unlocking and release of the finished roll during the switching of the take-up roller by the toothed disc, this invention provides a telescopic fixing component within the rectangular groove of the take-up roller to secure the inner tape cylinder. When the fixing plate of this telescopic fixing component unfolds outward, its outer edge abuts against the inner wall of the inner tape cylinder, achieving a firm fixation of the inner tape cylinder and ensuring no relative sliding between the inner tape cylinder and the take-up roller during the winding process. When the fixing plate retracts inward, the fixing plate disengages from the inner wall of the inner tape cylinder, facilitating easy removal of the finished tape roll from the take-up roller. During the process of the toothed disc rotating to switch the winding roller to a new station, the axial movement of the inclined top block in the telescopic fixing component is controlled by the limiting action of the push ring, thereby driving the synchronous unfolding and retraction of the fixing plate. Before the winding roller enters the winding station, the push ring drives the inclined top block to unfold the fixing plate and lock the inner cylinder of the tape. After the winding roller leaves the winding station, the push ring releases the limiting action of the inclined top block, and the fixing plate automatically retracts and unlocks the finished roll. Through the linkage between the toothed disc switching action and the push ring limiting action, the automatic clamping and release of "locking upon entry and unlocking upon exit" is realized.

[0019] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0020] Please see Figures 1-8 A conveying device for tape processing production includes a rewinding conveyor body 1 and a take-up roller 3, a release roller 7 rotatably mounted on the rewinding conveyor body 1, and a correction roller 6 and an anti-sticking roller 5 fixedly mounted on the rewinding conveyor body 1. The above structure is prior art. The general working process of the prior art is briefly described below: a large roll is placed on the release roller 7 and then fixed. The inner roll of tape is placed on the take-up roller 3 and then fixed. The end of the tape is pulled through the correction roller 6 and the anti-sticking roller 5 and then wound around the surface of the inner roll of tape. The equipment is started to rewind. After rewinding, the tape is cut. The finished roll is removed from the take-up roller 3 and then a new inner roll of tape is put on to rewind the next roll. A toothed disc 2 is rotatably mounted through one side of the rewinding conveyor body 1 (the toothed disc 2 is rotatably connected to the rewinding conveyor body 1 via a damping shaft, with its toothed end located in the internal cavity of the rewinding conveyor body 1). Multiple take-up rollers 3 are provided (four are used as an example in this invention), rotatably mounted at equal intervals on one side of the toothed disc 2. A rectangular groove 25 is provided at one end of the take-up roller 3 inside the rewinding conveyor body 1, and a telescopic fixing member is provided within the rectangular groove 25 to fix the inner cylinder of the tape. A sliding opening 10 is provided through one side of the rewinding conveyor body 1, and a cutting clamping member is provided on one side of the rewinding conveyor body 1 that is slidably connected to the sliding opening 10. When the take-up station... After the tape inner tube on the take-up roller 3 finishes winding, the control toothed disc 2 rotates at a predetermined angle to automatically switch the take-up roller 3. The switching process is as follows: the take-up roller 3 with the new tape inner tube is rotated to the take-up station, and the take-up roller 3 that has finished winding is rotated to one side to facilitate the subsequent removal of the finished tape roll and replacement of the new tape inner tube. The removal and replacement of the new tape inner tube do not interfere with the winding work. During each switching of the take-up roller 3, the unwound tape will naturally come into contact with the surface of the tape inner tube on the new station and automatically stick together using the tape's own adhesiveness. After that, the cutting clamp is activated to cut the tape. A rotating component is installed inside the rewinding conveyor body 1 to control the rotation of the toothed disc 2, thereby switching the take-up roller 3. It also controls the cutting clamp to cut the tape after the take-up roller 3 is switched. The cutting clamp includes a slide rod 15 slidably connected to the slide chute 10. An mounting plate 8 is fixedly installed at one end of the slide rod 15 outside the rewinding conveyor body 1. An arc-shaped pressure plate 11 and a cutter 12 are installed on one side of the mounting plate 8 (the mounting plate 8 is connected to the arc-shaped pressure plate 11 and the cutter 12 via telescopic rods; these telescopic rods are existing technology and are not shown in detail in the accompanying drawings. They consist of two mutually sliding fixed rods and a spring, a well-known existing structure). The arc-shaped pressure plate 11 is used to squeeze the tape tightly against the inner cylinder of the new tape, and the cutter 12 is used to... The tape is cut to facilitate its winding with the new tape inner cylinder. The toothed disc 2 has stop bars 9 fixedly installed at equal intervals around its perimeter to match the cutter 12. (When the toothed disc 2 rotates to switch the take-up roller 3, the wound tape roll will cause the unwound tape to wrap around the outside of the corresponding stop bar 9, facilitating the cutting by the cutter 12. At this time, the cut end of the unwound tape is a certain distance from the new tape inner cylinder, which is the reserved length. The cutter 12 first contacts the stop bar 9, and then the arc-shaped pressure plate 11 contacts the new tape inner cylinder.) The rotating component includes a power motor 18 fixedly installed inside the rewinding conveyor body 1. A half gear 19 that meshes with the toothed disc 2 is fixedly installed at the output end of the power motor 18. (When the half gear 19 meshes with the toothed disc 2, the half gear 19 rotates half a turn, and the toothed disc 2 rotates a quarter turn.) The half gear 19 rotates half a turn (then the gear disc 2 does not rotate). A fixed column 30 is fixedly installed on one side of the half gear 19. An I-shaped frame 31 is slidably installed on the inner wall of the rewinding conveyor body 1. The slide rod 15 and the fixed column 30 are slidably connected to the I-shaped frame 31. The starting motor 18 drives the half gear 19 to rotate half a turn (in the meshing state). The half gear 19 drives the gear disc 2 to rotate a quarter turn, switching the take-up roller 3. During this process, the fixed column 30 pushes the I-shaped frame 31 to move. The I-shaped frame 31 pushes the slide rod 15 to move. The slide rod 15 moves along the slide opening 10. The slide rod 15 drives the mounting plate 8 to move. The mounting plate 8 controls the movement of the arc-shaped pressure plate 11 and the cutter 12 (first moving away from the inner cylinder of the new tape, then moving back). (Reset), the power motor 18 drives the half gear 19 to rotate half a turn again. At this time, the half gear 19 does not mesh with the toothed disc 2 (the toothed disc 2 does not rotate. After the rotation is completed, it will maintain the state that is about to mesh when it rotates next time). During this process, when the mounting plate 8 controls the arc-shaped pressure plate 11 and the cutter 12, it first moves towards the new tape inner cylinder and then returns to the return position. When moving towards the new tape inner cylinder, the cutter 12 first contacts the stop bar 9 and cuts the tape that has been wound up. Then the arc-shaped pressure plate 11 moves to contact the new tape inner cylinder and applies a preset pressure to the end of the tape so that it is tightly adhered to the surface of the tape inner cylinder. After the winding roller 3 starts to rotate for rewinding, the arc-shaped pressure plate 11 can continue to press for a certain period of time under the drive of the telescopic rod before retracting and resetting. A telescopic pusher is slidably installed in the rectangular groove 25 to control the operation of the telescopic fixing component. A push ring 16 for controlling the extension and retraction of the telescopic pusher is fixedly installed in the rewinding conveyor body 1. A stepper motor 17 is installed in the rewinding conveyor body 1. A connecting component is provided between the stepper motor 17 and the telescopic pusher.

[0021] As a further technical solution of the present invention, the telescopic fixing member includes multiple placement openings on the periphery of the take-up roller 3, a fixing plate 4 is slidably disposed in the placement opening, and a spring telescopic member 32 is fixedly installed between the fixing plate 4 and the take-up roller 3. The fixing plate 4 is arc-shaped on the outer side of the take-up roller 3, and has an oblique opening on the inner side of the fixing plate 4. The telescopic pushing member includes a rectangular rod 28 slidably connected to the rectangular groove 25. Multiple oblique openings are fixedly installed at one end of the rectangular rod 28 within the rectangular groove 25. A matching inclined top block 29 is used to push the fixing plate 4 against the inner cylinder of the tape. A T-shaped rod 24 is fixedly installed at one end of the rectangular rod 28 outside the rectangular groove 25. A return spring 22 is fixedly installed between the T-shaped rod 24 and the take-up roller 3. An opening 14 is opened on one side of the push ring 16. The opening 14 is arc-shaped. The contact surface between the T-shaped rod 24 and the opening 14 is also arc-shaped. An annular sliding opening 20 is opened through one side of the push ring 16. The take-up roller 3 is rotatably connected to the gear plate 2 through a one-way bearing. 2. Before switching the take-up roller 3, the T-shaped rod 24 at the outer end of the lowest take-up roller 3 is located at the opening 14. At this time, due to the action of the return spring 22, the inclined top block 29 does not push the fixed plate 4. Due to the action of the spring extension member 32, the fixed plate 4 is in an inward retracted state, which makes it easy to remove the finished tape roll from the take-up roller 3. When the lowest take-up roller 3 moves away from the opening 14, the T-shaped rod 24 contacts the arc surface of the opening 14, squeezing the T-shaped rod 24. When the rectangular rod 28 is pushed to move, the return spring 22 is squeezed, the rectangular rod 28 pushes the inclined top block 29, the inclined top block 29 pushes the fixing plate 4, and the fixing plate 4 is unfolded outward (the spring telescopic member 32 is stretched). Its outer edge abuts against the inner wall of the tape inner tube, so as to achieve a firm fixation of the tape inner tube and ensure that there is no relative sliding between the tape inner tube and the take-up roller 3 during the winding process. At the same time, the other take-up roller 3, which is turned to the opening 14, releases the limit on one side of the T-shaped rod 24, and the corresponding fixing plate 4 retracts.

[0022] As a further technical solution of the present invention, the connecting component includes a rotating rod 13 fixedly connected to the output end of the stepper motor 17. The rotating rod 13 is rotatably connected to the push ring 16. The rotating rod 13 is located inside the annular slide 20. A rectangular opening 21 is provided at the outer end of the rotating rod 13. A rectangular slide groove 27 is provided at the outer end of the T-shaped rod 24. An arc-shaped block 23 is slidably arranged in the rectangular slide groove 27. A connecting spring 26 is fixedly installed between the arc-shaped block 23 and the rectangular slide groove 27. One end of the arc-shaped block 23 located inside the rectangular opening 21 is arched (the part of the arc-shaped block 23 located inside the rectangular opening 21 is semi-cylindrical). When the gear disk 2 rotates, it can squeeze the arc-shaped block 23 to shrink, which will not interfere with the rotation of the gear disk 2. The rectangular opening 21 has two flat sides that slide in contact with the inner wall of the rectangular opening 21 (at this time, the rotating rod 13 can rotate to drive the arc block 23 to rotate, the arc block 23 can be an iron block, and a magnet can be installed in the rectangular opening 21 so that it can fit more tightly when connected). During the rotation of the gear disk 2, the arc block 23 is located in the annular sliding opening 20. When the gear disk 2 rotates to switch the take-up roller 3 to the take-up position, the rectangular opening 21 corresponds to the rectangular sliding groove 27, and the arc block 23 goes deep into the rectangular opening 21. At this time, the stepper motor 17 is started to drive the rotating rod 13 to rotate. The rotating rod 13 drives the T-shaped rod 24 to rotate through the arc block 23. The T-shaped rod 24 drives the take-up roller 3 to rotate through the rectangular rod 28.

[0023] During work: Step 1: Start stepper motor 17 to begin winding. Start the stepper motor 17, which drives the rectangular rod 28 to rotate through the rotating rod 13, the arc block 23 and the T-shaped rod 24. The rectangular rod 28 drives the take-up roller 3 located at the take-up station to rotate, and the rewinding operation begins. Step 2: Rewinding complete, start the power motor 18 After the take-up roller 3 at the take-up station completes the take-up operation, the stepper motor 17 stops working and the power motor 18 is started, which drives the half gear 19 to rotate. The half gear 19 meshes with the gear plate 2, which drives the gear plate 2 to rotate a predetermined angle (a quarter turn) to automatically switch the take-up roller 3. The half gear 19 drives the I-shaped frame 31 to slide through the fixed column 30, which in turn drives the slide rod 15 and the mounting plate 8 to move. The mounting plate 8 first moves away from the new tape inner cylinder, and then moves back to the new tape inner cylinder to reset. Step 3: Automatic tape adhesion During the switching process, the unwound tape naturally contacts the surface of the tape inner cylinder at the new station, achieving automatic adhesion using the tape's own adhesiveness. Simultaneously, the arc-shaped block 23 at the end of the T-shaped rod 24 of the newly transferred winding roller 3 is squeezed and completely slides into the rectangular groove 27, and the connecting spring 26 is squeezed until the rectangular opening 21 at one end of the rotating rod 13 aligns with the rectangular groove 27. At this point, one end of the arc-shaped surface of the arc-shaped block 23 slides into the rectangular opening 21 (in this state, the stepper motor 17 can be started for winding). At the same time, the winding roller 3 that has been switched to the unloading station (the winding roller 3 at the lower station) moves its T-shaped rod 24 to the opening 14 of the push ring 16, releasing the compression. The fixing plate 4 automatically retracts and unlocks under the action of the spring telescopic component 32, and the finished roll can be easily removed. After the operator removes the finished roll, the new tape inner cylinder can be fitted onto the winding roller 3 at the unloading station. At this time, the fixing plate 4 is in a retracted state, which is convenient for installation. During the movement of the take-up roller 3 at the unloading station, the T-shaped rod 24 contacts the arc-shaped surface of the opening 14, squeezing the T-shaped rod 24 and pushing the rectangular rod 28 to move. The return spring 22 is squeezed, and the rectangular rod 28 pushes the inclined top block 29. The inclined top block 29 pushes the fixing plate 4, which unfolds the fixing plate 4 outward (the spring telescopic member 32 is stretched). Its outer edge abuts against the inner wall of the tape inner cylinder, achieving a firm fixation of the tape inner cylinder and ensuring that there is no relative sliding between the tape inner cylinder and the take-up roller 3 during the winding process. Step 4: Half gear 19 continues to rotate, triggering the cutting clamp. The half gear 19 continues to rotate (at this time, it disengages from the gear plate 2, and the gear plate 2 is stationary), and drives the I-shaped frame 31 to slide through the fixed column 30, thereby driving the slide rod 15 and the mounting plate 8 to move. The mounting plate 8 first moves towards the inner cylinder of the new tape, and then moves in the opposite direction to reset. During the process of the mounting plate 8 moving towards the inner cylinder of the new tape, the cutter 12 first contacts the stop bar 9 and cuts the tape that has been wound up. Then the arc-shaped pressure plate 11 moves to contact the inner cylinder of the new tape and applies pressure to the end of the tape, so that it is tightly adhered to the surface of the inner cylinder of the tape (the mounting plate 8 can also be maintained after the winding roller 3 starts to rotate for rewinding), and then retracts to reset after a certain period of time.
