Description

Technical Field

[0001] This application belongs to the technical field of winding and packaging equipment, specifically relating to a tape applicator and production line. Background Technology

[0002] Currently, winding machines are commonly used in the packaging and winding of waterproof membrane products. However, manual tape application remains a key factor limiting overall winding efficiency. Manual operation makes it difficult to precisely control the tape length and position, often resulting in tape that is too long or too short, and the tape length cannot be standardized. Current manual tape application methods typically only achieve single-sided application, failing to meet the requirement of double-sided tape application where both ends of the paper tube and the roll material need to be secured. After the initial tape application, the start button still needs to be pressed manually, preventing full automation of the winding process and hindering true "one-button start" or a fully closed-loop automatic cycle. Operators applying tape at close range before the machine is fully running and then need to press the control button afterward, posing a safety risk of being caught in moving parts or injured by mechanical devices. Insecure tape application leading to subsequent roll material detachment can also cause safety issues. Summary of the Invention

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a tape-applying device and production line to realize automatic mechanical tape application for packaging.

[0004] To achieve the above objectives, this application provides a tape applicator for applying tape to rolls of material to be packaged, the tape applicator comprising: The frame is equipped with a film roll placement shaft and an installation shaft, wherein the film roll placement shaft is for the tape to be wound and threaded. A pressure roller is sleeved on the mounting shaft and used to press the tape tightly onto the roll of material to be packaged; A rotating frame is hinged to the mounting shaft and has a cutting blade at one end away from the hinge point. The rotating frame can rotate relative to the frame and drive the cutting blade to reciprocate between a clearance position and an initial position. The cutting blade in the clearance position is used to avoid the tape, so that the pressure roller presses the tape tightly onto the roll to be packaged. The cutting blade in the cutting position is used to cut the tape. The first elastic connector is connected between the rotating frame and the machine frame and is used to drive the rotating frame to reset through its own elasticity.

[0005] In some embodiments, the tape applicator further includes: An air blowing shaft has multiple air outlets facing the pressure roller and is used to blow air onto the tape so that the non-adhesive side of the tape is tightly attached to the pressure roller.

[0006] In some embodiments, the tape applicator further includes: A connecting rod is provided, and the air blowing shaft is connected to the connecting rod. The connecting rod is hinged to the frame and can rotate relative to the frame, driving the air blowing shaft to reciprocate between a remote position and a pressing position. When the air blowing shaft is in the remote position, a clearance space is formed between the air blowing shaft and the pressure roller for the tape to pass through. When the air blowing shaft is in the pressing position, it is used to press the tape tightly against the pressure roller.

[0007] In some embodiments, the tape applicator further includes: The second elastic connector has one end connected to the frame and the other end connected to the connecting rod. The second elastic connector is used to reset the connecting rod.

[0008] In some embodiments, the tape applicator includes two air-blowing shafts, which are respectively disposed on both sides of the pressure roller in the horizontal radial direction.

[0009] In some embodiments, the cutting blade has blades on both sides in its width direction, the cutting blade is detachably mounted on the connecting plate of the rotating frame, and the width of the cutting blade is greater than the width of the connecting plate, so that the blades on both sides of the cutting blade protrude from the connecting plate.

[0010] In some embodiments, the tape applicator further includes: A roller is connected to the rotating frame via a bearing and is able to roll around the bearing. The roller protrudes from the connecting plate and is used to rub against the roll material to drive the rotating frame to move.

[0011] In some embodiments, the frame includes a first main frame and a second main frame, which are connected by the mounting shaft, and the pressure roller is sleeved on the mounting shaft and can roll through the mounting shaft.

[0012] In some embodiments, the tape applicator further includes: A guide roller, connected between the first main frame and the second main frame and capable of rolling along its own axis, is disposed between the film roll placement shaft and the pressure roller and is used to guide the tape.

[0013] A second aspect of this application provides a production line including a winding machine, a clamping device, and a tape applicator as described above. The winding machine has a rotatable air shaft on which the roll of material to be packaged is wound. The tape applicator is located above the air shaft. The clamping device is used to clamp the tape applicator and can drive the tape applicator to move.

[0014] Through the above technical solution, the cooperation between the rotating frame and the cutting blade ensures the automation of the tape application and cutting process. When the cutting blade is in the avoidance position, the pressure roller can press the tape firmly onto the roll material without obstruction, improving application efficiency and accuracy. At the cutting position, the rotating frame drives the cutting blade to reset quickly, completing the cut and preventing the tape from being too long or loose. This tape application device uses mechanical methods to apply tape, reducing manual intervention and increasing packaging speed, making it particularly suitable for production line operations. The self-resetting mechanism of the first elastic connector ensures that the cutting blade automatically returns to its initial position after each operation, preventing safety accidents caused by blade residue and enhancing equipment reliability while reducing the failure rate. Furthermore, the entire structure is simple and compact, utilizing hinges and elastic elements for motion control, making it easy to manufacture and maintain, and reducing production and operating costs.

Explanation of reference numerals in the attached figures Detailed Implementation

[0017] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0018] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0019] like Figure 1 and Figure 2As shown, the first aspect of this application provides a tape applicator 1 for applying tape to a roll of material 3 to be packaged. The tape applicator 1 includes a frame 11, a pressure roller 12, a rotating frame 13, and a first elastic connector 14. The frame 11 is provided with a film roll placement shaft 111 and a mounting shaft 112. The film roll placement shaft 111 is for the tape roll to be threaded through. The pressure roller 12 is sleeved on the mounting shaft 112 and is used to press the tape tightly onto the roll of material 3 to be packaged. The rotating frame 13 is hinged to the mounting shaft 112 and has a cutting blade 131 at one end away from the hinge point. The rotating frame 13 can rotate relative to the frame 11 and drive the cutting blade 131 to reciprocate between a clearance position and an initial position. The cutting blade 131, positioned in the avoidance position, avoids the tape, allowing the pressure roller 12 to press the tape firmly onto the roll 3 to be packaged. The cutting blade 131, positioned in the cutting position, cuts the tape. The first elastic connector 14 is connected between the rotating frame 13 and the frame 11 and is used to drive the rotating frame 13 to reset through its own elasticity. The first elastic connector 14 can be a spring 1113 or other elastic connector. When the rotating frame 13 rotates to the avoidance position, it stretches the first elastic connector 14, causing the first elastic connector 14 to generate elastic potential energy. During the reset process, the first elastic connector 14 releases its elastic potential energy, driving the rotating frame 13 to reset.

[0020] The frame 11 serves as the basic support structure, equipped with a film roll placement shaft 111 and a mounting shaft 112. The film roll placement shaft 111 is used to thread the tape roll, providing a source of tape. A pressure roller 12 is fitted over the mounting shaft 112, which presses the tape tightly against the surface of the roll material 3 during the pasting process, ensuring a secure bond. The rotating frame 13 is connected to the frame 11 via the mounting shaft 112, and a cutter 131 is mounted at the end away from the hinge point. The entire rotating frame 13 can rotate around the mounting shaft 112 to drive the cutter 131 to reciprocate between a clearance position and an initial position. The clearance position refers to the cutter 131 rotating away from the tape pasting area to avoid interfering with the pressing action of the pressure roller 12; the initial position corresponds to the cutting position, where the cutter 131 contacts the tape and performs the cutting action. A first elastic connector 14 is used to automatically pull the rotating frame 13 back to its initial position after rotation, forming a self-resetting mechanism. It is understood that the end of the rotating frame 13 away from the hinge point is the movable end, and the cutting blade 131 is located at the movable end. The other end of the rotating frame 13 is the connecting end, and it is connected to the first elastic connector 14 at the connecting end. The hinge point between the rotating frame 13 and the mounting shaft 112 is located in the middle of the rotating frame 13 and close to the connecting end. That is, the distance between the hinge point and the connecting end is less than the distance between the hinge point and the movable end. This makes the movable end have a larger lever arm when the rotating frame 13 rotates around the hinge point relative to the frame 11. This can drive the connecting end to rotate and stretch the first elastic connector 14 at the connecting end, so that the first elastic connector 14 has elastic potential energy to drive the rotating frame 13 to reset. The cooperation between the rotating frame 13 and the cutting blade 131 ensures the automation of the tape application and cutting process. When the cutting blade 131 is in the avoidance position, the pressure roller 12 can press the tape firmly onto the roll material 3 without obstruction, improving the application efficiency and accuracy. In the cutting position, the rotating frame 13 drives the cutting blade 131 to reset quickly, completing the cut and preventing the tape from being too long or loose. The tape application device 1 of this utility model uses machinery to apply tape, reducing manual intervention and increasing packaging speed, making it particularly suitable for production line operations. The self-resetting mechanism of the first elastic connector 14 ensures that the cutting blade 131 automatically returns to its initial position after each operation, which not only prevents safety accidents caused by blade residue but also enhances the reliability of the equipment and reduces the failure rate. In addition, the entire structure is simple and compact, and the motion control is achieved by using hinges and elastic connectors, making it easy to manufacture and maintain, and reducing production and usage costs.

[0021] In some implementations, such as Figure 2 and Figure 3As shown, the tape application device 1 also includes an air blowing shaft 15, which has multiple air outlets 151 facing the pressure roller 12. These outlets are used to blow air onto the tape, ensuring the non-adhesive side of the tape adheres tightly to the pressure roller 12. The air blowing shaft 15 has multiple air outlets 151 distributed axially, with the outlets 151 directly facing the surface of the pressure roller 12. It should be noted that the air blowing shaft 15 is a long shaft, and both ends are sealed. The air blowing shaft 15 also has an air inlet 152, which connects to an external air source for continuous air blowing onto the tape. Alternatively, in this embodiment, one end of the air blowing shaft 15 is sealed, while the other end is open, serving as the air inlet 152. The air blowing shaft 15 can be directly connected to the frame 11 or connected to the frame 11 via other components. When the device is running, the air blowing shaft 15 continuously blows air onto the tape through its internal air passage. The airflow acts on the tape, and the airflow adsorption effect forces the non-adhesive side of the tape to adhere tightly to the outer circumference of the pressure roller 12. This design supplements the physical constraint of the pressure roller 12 on the tape through pneumatic principles. Especially when the tape is peeled from the roll, the airflow from the air blowing shaft 15 can suppress the deviation of the tape caused by its own deformation or static electricity. Through airflow adsorption, the non-adhesive side of the tape is forced to adhere to the surface of the pressure roller 12, preventing the tape from twisting, shifting, or partially detaching during the conveying process, ensuring that the tape always moves along the preset trajectory. When the pressure roller 12 presses the tape against the roll 3, the tape has been pre-tensioned and straightened by the airflow, reducing the generation of air bubbles or wrinkles, making the adhesion between the tape and the surface of the roll 3 smoother and tighter. The air blowing suppresses the natural curling of the tape caused by static electricity or material elasticity, preventing the tape from accidentally wrapping around the pressure roller 12 or blocking the path of the cutting blade 131, reducing the frequency of downtime for adjustment, and improving packaging efficiency.

[0022] In some implementations, such as Figure 2 and Figure 3As shown, the tape applicator 1 also includes a connecting rod 16, and an air blowing shaft 15 is connected to the connecting rod 16. The connecting rod 16 is hinged to the frame 11 and can rotate relative to the frame 11, driving the air blowing shaft 15 to reciprocate between a remote position and a pressing position. When the air blowing shaft 15 is in the remote position, a clearance space is formed between it and the pressure roller 12 for the tape to pass through. When the air blowing shaft 15 is in the pressing position, it is used to press the tape tightly against the pressure roller 12. The connecting rod 16 is hinged to the frame 11, and its two ends are respectively connected to the air blowing shaft 15 and the hinge point, so that the air blowing shaft 15 can rotate around the hinge point with the connecting rod 16. The connecting rod 16 drives the air blowing shaft 15 to switch between the away position and the pressing position. When the air blowing shaft 15 is in the away position, the air blowing shaft 15 is separated from the pressure roller 12, and a clearance space is formed between the two, which makes it easy for the operator to thread the tape or change the film roll. When the air blowing shaft 15 is in the pressing position, the air blowing shaft 15 rotates to approach the pressure roller 12, and blows the non-adhesive side of the tape toward the surface of the pressure roller 12 by blowing air. The clearance space allows the tape threading path to be completely open, enabling tape installation or replacement without disassembling parts, significantly reducing downtime. At the pressing position, the airflow from the air shaft 15 eliminates the gap between the tape and the pressure roller 12, especially for high-viscosity tapes or high-speed operation, preventing the tape from detaching from the pressure roller 12 due to centrifugal force, ensuring that the tape remains flat and wrinkle-free, and improving the flatness of subsequent bonding to the roll 3. Moreover, the mechanical pressing force is adjustable, which can flexibly adapt to tapes of different thicknesses and hardnesses.

[0023] In some embodiments, the tape application device 1 further includes a second elastic connector 17. One end of the second elastic connector is connected to the frame 11, and the other end is connected to the connecting rod 16. The second elastic connector 17 is used to reset the connecting rod 16 through its own elasticity. One end of the second elastic connector 17 is fixed to a preset anchor point on the frame 11, and the other end is directly connected to the connecting rod 16 driving the air blowing shaft 15. When the connecting rod 16 is subjected to external force (such as manual operation or linkage mechanism drive) and rotates around the hinge point of the frame 11, the second elastic connector 17 deforms and stores energy. Once the external force is removed, the elastic connector releases the stored energy and automatically pulls the connecting rod 16 back to the initial position through contraction or rebound force. The elastic reset mechanism of the second elastic connector 17 ensures that the connecting rod 16 and the air blowing shaft 15 can accurately return to the pressing position without manual intervention when they are in the original position, greatly improving the smoothness of continuous operation. At the same time, the buffering effect of the elastic connector can absorb the inertial impact during the movement of the connecting rod 16, reduce the mechanical wear of the hinge structure, and extend the life of key components.

[0024] In some embodiments, the tape-applying device 1 includes two air-blowing shafts 15, which are respectively disposed on both sides of the pressure roller 12 in the horizontal radial direction. It should be noted that the film roll placement shafts 111 disposed on the frame 11 can also be two, respectively disposed on both sides of the pressure roller 12, and the two air-blowing shafts 15 are also correspondingly disposed on both sides of the pressure roller 12. That is, in this embodiment of the invention, the tape-applying device 1 adopts a double-sided symmetrical structure design, with two film roll placement shafts 111 and two air-blowing shaft 15 assemblies respectively disposed on both sides of the pressure roller 12. The two film roll placement shafts 111 are symmetrically arranged on the left and right sides of the pressure roller 12, each independently carrying a roll of tape; simultaneously, the two air-blowing shafts 15 are respectively disposed corresponding to two rolls of tape, also located on the left and right sides of the pressure roller 12, with the air outlets 151 of the two air-blowing shafts 15 still facing the pressure roller 12. This double-sided layout allows the device to form two independent but cooperative tape conveying units. By operating the dual tape channels synchronously, tape can be applied to both sides of the tape applicator 1, adapting to the high-volume operation requirements of high-speed production lines. At the same time, the redundant design ensures that the other side can continue to operate when the tape on one side runs out, greatly reducing the frequency of downtime for replacement. In addition, the symmetrical layout makes the frame 11 bear the force evenly, reduces the wear of the pressure roller 12 under off-center load, extends the equipment life, and achieves high-efficiency and high-stability dual-station collaborative packaging as a whole.

[0025] In some embodiments, the cutting blade 131 has cutting edges on both sides in its width direction. The cutting blade 131 is detachably mounted on the connecting plate 132 of the rotating frame 13. The width of the cutting blade 131 is greater than the width of the connecting plate 132, so that the cutting edges on both sides of the cutting blade 131 protrude from the edge of the connecting plate 132. Specifically, the rotating frame 13 is U-shaped and includes the connecting plate 132 and the rotating rod 133. One end of the rotating rod 133 is hinged to the frame 11, and the connecting plate 132 is connected to the other end of the rotating rod 133. The U-shaped rotating frame 13 makes the connection structure of the cutting blade 131 more stable. The double-sided cutting edges allow the cutting blade 131 to cut the tape bidirectionally without adjusting its direction during reciprocating motion, which is especially suitable for high-speed continuous operation scenarios and avoids the problem of frequent blade replacement caused by wear of one-sided cutting edges. The design of the cutting edges protruding from the connecting plate 132 ensures that the cutting edges can cut the tape. At the same time, the detachable structure makes it easy to replace the worn cutting blade 131 separately rather than the entire rotating frame 13 assembly, which greatly reduces maintenance costs and downtime.

[0026] In some embodiments, the tape applicator 1 further includes a roller 18, which is connected to the rotating frame 13 via a bearing 181 and can roll around the bearing 181. The roller 18 protrudes from the edge of the connecting plate 132 and is used to rub against the roll material 3 to drive the rotating frame 13 to move. The roller 18 is connected to the rotating frame 13 via the bearing 181, enabling free rolling around the axis. The outer circumferential surface of the roller 18 protrudes from the edge of the connecting plate 132, forming the only rolling interface between the rotating frame 13 and the outside. During operation, the roller 18 directly contacts the surface of the roll material 3 to be packaged, driving itself to roll through friction, while simultaneously transmitting motion to the rotating frame 13, causing it to rotate around the hinge point. The rolling friction mechanism transforms the contact between the rotating frame 13 and the roll material 3 into low-resistance rolling friction, making the rotating frame 13 move more smoothly on the surface of the roll material 3. The structure of the roller 18 protruding from the connecting plate 132 forms a physical isolation layer, which prevents the connecting plate 132 and the cutting blade 131 from directly contacting the roll material 3. This not only prevents the cutting blade 131 from accidentally scratching the surface of the roll material 3 or surrounding equipment, but also eliminates the dust and debris generated by the connecting plate 132 rubbing against the roll material 3, thus ensuring the continuity of the automated packaging process and the safety of operation.

[0027] In some implementations, such as Figure 4 and Figure 5 As shown, the frame 11 includes a first main frame 113 and a second main frame 114, which are connected by a mounting shaft 112. The pressure roller 12 is sleeved on the mounting shaft 112 and can roll through it. The first main frame 113 and the second main frame 114 are rigidly connected by the mounting shaft 112 to form an integral support structure. The mounting shaft 112 not only serves as the connecting hub of the two main frames, but also acts as the rolling axis of the pressure roller 12 and the hinge point of the rotating frame 13. The pressure roller 12 is sleeved on the outside of the mounting shaft 112 through a bearing 181, so that it can maintain the overall structural stability with the mounting shaft 112, and can also rotate freely around the shaft independently. The mounting shaft 112 connects the distributed load to the first main frame 113 and the second main frame 114, effectively suppressing vibration and deformation during equipment operation, ensuring uniform pressure distribution between the pressure roller 12 and the roll material 3, and avoiding uneven tape adhesion caused by deformation of the frame 11. The pressure roller 12 is directly sleeved on the mounting shaft 112, which not only eliminates the wobble of the pressure roller 12 by utilizing the high rigidity of the mounting shaft 112, but also reduces drive energy consumption through the rolling of the bearing 181, making the tape conveying more stable and continuous. The rotating frame 13 can also rotate around the mounting shaft 112, realizing multiple uses of one shaft. Multiple support shafts 115 are also connected between the first main frame 113 and the second main frame, which further ensure the stability of the frame 11.

[0028] In some embodiments, the first main frame 113 also has an upward extension 1131 with a mounting hole 1132. A mounting seat 1133 passes through the mounting hole 1132. The film roll placement shaft 111 is connected to the mounting hole 1132 through the mounting seat 1133. The film roll placement shaft 111 integrates a lead screw structure. One end of the lead screw is threaded to a first adjusting nut 1111, which axially clamps the tape roll between the end cap 1112 and the first main frame 113. The other end is sequentially fitted with a spring 1113, a spring adjustment ring 1114, and a second adjusting nut 1115. The spring adjustment ring 1114 is threaded with the lead screw. Rotating the adjustment ring can compress the spring 1113, allowing it to store energy and press against the mounting seat 1133, forming an adjustable preload system. The film roll placement shaft 111 significantly improves the stability and adaptability of the tape roll fixing. The first adjusting nut 1111 precisely locks the tape roll through mechanical limiting, preventing axial movement or detachment. The synergistic effect of the spring 1113 and the compression spring adjusting ring 1114 gives the system dynamic buffering capability. When the diameter of the tape roll decreases due to wear, the spring 1113 automatically releases the preload force to push the screw axially, continuously maintaining contact between the tape roll and the end cap 1112, avoiding slippage caused by loose tape rolls in traditional fixing methods. At the same time, the threaded adjustment mechanism allows for manual fine-tuning of the preload force to adapt to tape rolls of different widths or materials, fundamentally ensuring smooth and continuous tape conveying, reducing the risk of tape breakage, and extending the effective operating cycle of the equipment.

[0029] In some embodiments, the tape application device 1 further includes a guide roller 19, connected between the first main frame 113 and the second main frame 114 and capable of rolling along its own axis. The guide roller 19 is disposed between the film roll placement shaft 111 and the pressure roller 12 for guiding the tape. The guide roller 19 and the pressure roller 12 are also connected between the first main frame 113 and the second main frame 114, forming a rigid support spanning the first main frame 113 and the second main frame 114, and ensuring that the guide roller 19 can roll freely along its own axis. The axial length of the guide roller 19 covers the distance between the first main frame 113 and the second main frame 114, and its outer circumferential surface is precisely positioned in the tape conveying path, directly receiving the tape released from the film roll. This eliminates the slack or twisting caused by the tape being suspended after being released from the film roll, ensuring that the tape always enters the working area of ​​the pressure roller 12 in a taut state, fundamentally avoiding misalignment caused by tape slippage or deviation. The guide roller 19 is fixed between the first main frame 113 and the second main frame 114, making it a rigid guide rail for conveying the tape and improving the overall stability of the frame 11; at the same time, the rolling contact greatly reduces the wear on the tape surface, especially protecting the integrity of the printed tape pattern.

[0030] The second aspect of this application provides a production line, which includes a winding machine 2, a clamping device, and a tape-applying device 1 as described above. The winding machine 2 has a rollable air shaft, on which the roll material 3 to be packaged is wound. The tape-applying device 1 is located above the air shaft. The clamping device is used to clamp the tape-applying device 1 and can drive the tape-applying device 1 to move. The winding machine 2, with the rollable air shaft as its core, is used to fix and drive the roll material 3 to be packaged to rotate. The tape-applying device 1 is suspended above the air shaft by the clamping device, and its position is corresponding to that of the roll material 3. The clamping device grips the tape-applying device 1 through a robotic arm or slide rail structure, realizing its controllable movement in the horizontal or vertical direction. The spatial arrangement of the three components allows the pressure roller 12, cutting blade 131, and other functional components of the tape-applying device 1 to directly act on the surface of the roll material 3. The clamping device can be automated using existing single-chip microcomputers to form a closed-loop operation system, realizing full-process automation and high-precision control of the packaging of the roll material 3. The air shaft's rolling characteristic allows the roll material 3 to be rotated to any position in its circumference to reach the adhesive application station. Combined with the clamping device's flexible movement of the tape application device 1, it enables precise multi-segment positioning and application of the roll material 3 along its axial direction, meeting the needs of complex packaging trajectories. Furthermore, it ensures consistent tape length for a more aesthetically pleasing finish. The continuously suspended structure of the tape application device 1 avoids frequent disassembly and assembly. The stable gripping by the clamping device ensures uniform and controllable pressure from the pressure roller 12 on the roll material 3, completely eliminating pressure fluctuations caused by manual operation. Simultaneously, the alignment design of the air shaft and the tape application device 1 maximizes the use of the working space, shortens the tape conveying path, and reduces the risk of tape deviation during high-speed operation. Ultimately, this results in a highly efficient, precise, and replicable standardized production line, significantly improving the yield and production capacity of the roll material 3 packaging.

[0031] Before working on the production line, such as Figure 6 As shown, first, insert the paper tube 2a onto the air shaft. The winding machine 2 conveys the starting end of the roll 3, stopping just above the inserted paper tube, waiting for the starting end to be taped. This attaches the starting end of the roll 3 to the paper tube 2a, so that the air shaft can rotate the paper tube 2a to wind up the roll 3. When taping the starting end, the clamping device drives the entire tape application device 1 to press down, while the air shaft 15 blows air, causing the un-taped side of the tape to adhere tightly to the pressure roller 12. Figure 7 As shown, after pressing down, roller 18 presses onto the roll 3. At this time, the adhesive side of the tape adheres to the roll 3. During the continuous pressing process, roller 18 will roll due to the force, driving the rotating frame 13 and the cutting blade 131 to rotate to the avoidance position. Due to the avoidance of the rotating frame 13, the pressure roller 12 can directly contact the tape and press the tape tightly onto the roll 3 through downward pressure. Figure 8 As shown, the clamping device then moves the tape applicator 1 horizontally, causing the tape to adhere to the paper tube 2a, thus bonding the starting end of the roll 3 to the paper tube 2a for easier subsequent winding. Figure 9As shown, after the tape is applied, the clamping device drives the tape applicator 1 to rise. At this time, the rotating frame 13 will return to its initial position due to the elastic potential energy of the first elastic connector 14. During the process of the rotating frame 13 driving the cutting blade 131 to return, the cutting blade 131 will cut the tape on the return path. Then, the clamping device continues to drive the tape applicator 1 to rise again, returning to the starting position. Figure 10 As shown, during the winding process, the air shaft inflates and expands to press against the inner wall of the paper tube 2a, then begins to rotate, driving the paper tube 2a to rotate and wind up. The roll 3 is continuously wound onto the paper tube 2a until it reaches the specified length, at which point the winding is complete. Figure 11 As shown, when winding is about to be completed, the clamping device drives the tape applicator 1 to press down, causing the roller 18 to contact the roll material 3. The frictional force of clockwise winding causes the roller 18 to roll to the right, driving the rotating frame 13 and the cutting blade 131 to rotate to the right. At the same time, the adhesive side of the tape adheres to the roll material 3. Figure 12 As shown, when the roll reaches the specified length, the cutter of the winding machine 2 cuts the roll 3, and the air shaft continues to rotate, driving the roll 3 to rotate, while also stretching the tape. The stretched tape is pressed tightly onto the roll 3 by the pressure roller 12, and the end of the roll 3 is glued in place. Figure 13 As shown, the clamping device then drives the tape applicator 1 to rise, and the cutting blade 131, which has returned to its initial position, cuts the tape, thus completing the packaging of a roll 3.

[0032] Through the technical solution of this utility model, the cooperation between the rotating frame 13 and the cutting blade 131 ensures the automation of the tape pasting and cutting process. When the cutting blade 131 is in the avoidance position, the pressure roller 12 can press the tape firmly onto the roll material 3 without obstruction, improving pasting efficiency and accuracy. In the cutting position, the rotating frame 13 drives the cutting blade 131 to reset quickly, thus avoiding excessive tape length or looseness. The tape-applying device 1 of this utility model uses machinery to apply tape, reducing manual intervention and increasing packaging speed, making it particularly suitable for production line operations. The self-resetting mechanism of the first elastic connector 14 ensures that the cutting blade 131 automatically returns to its initial position after each operation, which not only prevents safety accidents caused by blade residue but also enhances the reliability of the equipment and reduces the failure rate. In addition, the entire structure is simple and compact, using hinges and elastic elements to achieve motion control, making it easy to manufacture and maintain, and reducing production and usage costs. The technical solution of this utility model enables double-sided tape application, making it more practical. Furthermore, the production line provided by this utility model enables fully automated winding and packaging, eliminating the need for manual tape application and allowing the entire process to be completed without human intervention, thus improving packaging efficiency.
