For production lines that need to process three-layer coils, using this device may lead to a decrease in production efficiency. Because it is necessary to find other methods to deal with this part of the roll, or to decompose the three-layer roll into a double-layer roll for processing, which will increase processing time and cost. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a three-layer coil stripping and pulling mechanism, which solves the problems raised in the background technology.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] A three-layer coil stripping and pulling mechanism comprises a back plate, on which a coil to be separated, a guide roller and a winding shaft are mounted;

[0007] The winding shaft is located below the roll to be separated, the back plate is located above the winding shaft and is provided with a first pre-tightening block, a first guide block is provided above the first pre-tightening block, the first guide block is located at one end of the double-headed cylinder, a second guide block is provided at the end of the double-headed cylinder away from the first guide block, two stripping modules are provided at one end of the back plate located at the double-headed cylinder close to the second guide block, and the two stripping modules are respectively above and below the double-headed cylinder, and a second pre-tightening block is provided on the back plate below the double-headed cylinder;

[0008] The material roll to be separated is guided by the guide roller and passes through the first pre-tightening block, the stripping module above the double-headed cylinder of the first guide block, the second guide block, the stripping module below the double-headed cylinder and the second pre-tightening block in sequence, and the material roll to be separated is stripped of the first separation layer by the stripping module above the double-headed cylinder, and the material roll to be separated is stripped of the second stripping layer by the stripping module below the double-headed cylinder.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a first motor is installed on the back plate, and the first motor, the material roll to be separated, the first pre-tightening block and the second pre-tightening block are located on the back side of the back plate and are all installed with a transmission wheel, and the first motor, the material roll to be separated, the first pre-tightening block and the second pre-tightening block are connected through a transmission wheel and a synchronous belt.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] Through the transmission connection mode of the synchronous belt and the transmission wheel, the power transmission between the first motor and the material roll to be separated, the first pre-tightening block and the second pre-tightening block is realized, which has the advantages of high transmission efficiency and stable operation. This transmission mode can ensure that the various components keep running synchronously during the working process, reduce the tension change caused by the inconsistent speed between different components, avoid the problems of slipping, jamming or tearing of the material roll during the transmission process, and also facilitate the power coordination and control of the whole system, which helps to improve the stability and reliability of the production process. In addition, since the synchronous belt has a certain elasticity and buffering property, it can also reduce the mechanical impact between components to a certain extent and extend the service life of the equipment.

[0013] Furthermore, a second motor is installed on the back side of the reel located at the back of the back plate, and the reel is driven by the second motor to reel in the target material roll.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] Using a second motor to drive the reel independently can achieve precise control of the reel speed. This allows the reel speed of the target material to be flexibly adjusted according to production needs, ensuring the tightness and uniformity of the reel, and avoiding problems such as loose or wrinkled material due to too fast or too slow reel speed. Moreover, the independent motor drive method provides sufficient power for the reeling process, ensuring the efficiency of the reeling operation, making the entire mechanism applicable to reels of different thicknesses and materials, improving the versatility and applicability of the equipment, and ensuring the quality of the final product.

[0016] Furthermore, the stripping module is in the shape of a triangular prism, and a separation block is provided at one corner of the stripping module. A receiving groove is provided behind the separation block and at two outer corners of the stripping module. A first guide shaft is rotatably installed in the receiving groove. The separation block is used to strip the material roll to be separated, and the separation block is used to guide the target material roll, the second stripping layer and the first separation layer after stripping.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The triangular prism-shaped stripping module design, with its unique shape characteristics, can effectively strip the three-layer roll material through the separation block. The separation block is located at a corner of the stripping module and can cut into the bonding layer of the roll at a suitable angle, making the stripping process smoother and more efficient. The accommodating groove and the first guide shaft set behind the separation block and at the other two corners not only provide accommodating space for the layers of material after stripping, but also can accurately guide them, avoiding the entanglement or deviation of the predetermined trajectory between the layers of material after stripping, ensuring that the layers of material can continue to be transmitted in an orderly manner after stripping, improving the accuracy and quality of the stripping operation, and also facilitating subsequent processing and handling procedures.

[0019] Furthermore, a guide groove is formed at one end of the first guide block and the second guide block away from the double-headed cylinder, and a second guide shaft is provided on the first guide block and the second guide block. When the material roll to be separated passes through the first guide block, the material roll to be separated is guided through the guide groove by the second guide shaft.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The cooperation of the guide groove on the first guide block and the second guide shaft provides a precise guide path for the roll to be separated. When the roll passes through the first guide block, the second guide shaft guides the roll into the guide groove, ensuring that the roll can accurately move along the predetermined route in a complex transmission path, preventing the roll from deflecting, shaking or misaligning during operation, and laying a good foundation for subsequent peeling and winding operations. This precise guiding method helps to improve the working accuracy of the entire mechanism, reduce process errors caused by inaccurate roll transmission, and improve product consistency and quality.

[0022] Furthermore, a fixed roller is rotatably mounted on the first pre-tightening block and the second pre-tightening block, the transmission wheels of the first pre-tightening block and the second pre-tightening block are transmission-connected to the fixed roller, and a fixed frame is movably mounted on one side of the fixed roller in the first pre-tightening block and the second pre-tightening block, and a movable roller is rotatably mounted on the fixed frame.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The fixed roller and the movable roller are arranged on the first pre-tightening block and the second pre-tightening block, which can effectively pre-tighten and support the material roll to be separated. The fixed roller is a stable supporting component, which is connected to the transmission wheel to ensure the power transmission of the pre-tightening block, while the movable roller can adjust the position according to the thickness and state of the material roll. They cooperate with each other to provide a stable transmission channel for the material roll, ensuring that the material roll maintains appropriate tension during the transmission process. This helps to avoid the material roll from being loose or too tight during the pre-tightening process, improves the transmission stability of the material roll, reduces the quality problems such as wrinkles and stretching deformation caused by uneven tension of the material roll, and ensures the smooth progress of subsequent stripping and winding operations.

[0025] Furthermore, a threaded rod is rotatably mounted on the fixed frame, and the threaded rod passes through the first pre-tightening block or the second pre-tightening block, and the threaded rod is transmitted by threaded engagement with the first pre-tightening block or the second pre-tightening block. A handle is provided at the end of the threaded rod, and the threaded rod is driven to rotate by the handle, thereby causing the fixed frame to move back and forth in the first pre-tightening block or the second pre-tightening block, so that the first pre-tightening block or the second pre-tightening block clamps the material roll to be separated through the movable roller and the fixed roller.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The handle drives the threaded rod to rotate, and the threaded meshing transmission drives the fixed frame to move forward and backward, realizing the precise adjustment of the spacing between the movable roller and the fixed roller, thereby realizing the flexible clamping of the coil to be separated. The operator can easily adjust the clamping force by turning the handle according to the coils of different thicknesses and materials, so that the pre-tightening block can adapt to different working conditions. This manual adjustment method is simple and easy, does not require complex tools and equipment, and can also ensure that the ideal pre-tightening effect can be achieved when processing coils of different production batches or different specifications, improving the adaptability of the equipment and the convenience of operation, and helping to improve the work efficiency and product quality of the entire mechanism.

[0028] The present invention provides a three-layer coil stripping and pulling mechanism, which has the following beneficial effects:

[0029] The reel is driven by a second motor located on the back of the back plate, which provides a stable and powerful power source for the reeling of the target material. By directly driving the reel with the motor, the speed and tension of the reel can be accurately controlled to ensure the stability of the reeling process and avoid reeling quality problems caused by insufficient or unstable power, such as loose rolls and wrinkles. Compared with some methods that rely on mechanical transmission to drive the reeling indirectly, this design significantly improves the reeling efficiency and is suitable for large-scale, continuous production operations.

[0030] The first motor is connected to the material roll to be separated, the first pre-tightening block and the second pre-tightening block through the transmission wheel and the synchronous belt. This transmission method has high synchronization and can ensure that all components maintain a coordinated and consistent motion state during operation. When the first motor is started, it can simultaneously drive the unwinding of the material roll to be separated, the movement of the first pre-tightening block and the second pre-tightening block, so that the entire coil material transmission and pre-processing process is completed in one go, reducing the problems of jamming and pulling caused by the uncoordinated movement between components, and improving the operation stability and reliability of the overall mechanism.

[0031] During the transmission process, the roll to be separated passes through multiple carefully designed guide components. The guide roller first guides the roll preliminarily so that it can smoothly enter the subsequent processing flow. Then, the second guide shaft and guide groove are respectively provided on the first guide block and the second guide block. When the roll to be separated passes through the first guide block, the second guide shaft can accurately guide the roll through the guide groove, providing accurate path guidance for the transmission of the roll. This multi-component coordinated guide design effectively avoids the roll from deflecting or shaking during the transmission process, ensures that the roll is always in a stable operating state, and provides a reliable material basis for subsequent stripping operations.

[0032] The unique design of the stripping module further enhances the guiding effect on the material roll. The stripping module is in the shape of a triangular prism, and a separation block is provided at one corner thereof for stripping the material roll to be separated. At the same time, a receiving groove is provided at the rear of the separation block and at the other two corners, and a first guide shaft is rotatably installed in the receiving groove. When the material roll is stripped by the separation block, the first guide shaft can guide the stripped target material roll, the second stripping layer and the first separation layer in time to prevent them from being entangled with each other or deviating from the predetermined transmission path, ensuring that the stripped layers of material can continue to be transmitted in an orderly manner, greatly improving the operating stability and reliability of the entire mechanism.

[0033] The clamping device in the first pre-tightening block and the second pre-tightening block is cleverly and flexibly designed. On each pre-tightening block, a fixed roller is rotatably installed, which is connected to the transmission wheel to ensure that the material roll can be stably supported and transmitted during the transmission process. At the same time, on one side of the fixed roller, a fixed frame is movably installed, and a movable roller is rotatably installed on the fixed frame. By rotating the threaded rod (driven by the handle) and utilizing the threaded meshing transmission between the threaded rod and the first pre-tightening block or the second pre-tightening block, the fixed frame can be moved back and forth in the pre-tightening block. This design allows the operator to flexibly adjust the spacing between the movable roller and the fixed roller according to the different thickness, material and other characteristics of the material roll to be separated, thereby achieving precise clamping of the material roll to be separated. It can ensure that the material roll will not slip, wrinkle or other problems due to being too loose during the transmission process, and will not be damaged due to being too tight, which greatly improves the adaptability of the mechanism to different types of coils.

[0034] Two stripping modules are set on the back plate at one end of the double-headed cylinder near the second guide block, and are located above and below the double-headed cylinder respectively. This unique upper and lower layout design enables the mechanism to strip three layers of coils at the same time. The coil to be separated passes through the stripping module above and the stripping module below the double-headed cylinder in turn, and the first separation layer and the second stripping layer are stripped out respectively. Compared with the traditional layer-by-layer stripping method, the stripping time is greatly shortened and the work efficiency is improved. It is especially suitable for industrial production scenarios with high production efficiency requirements.

[0035] The stripping module adopts a triangular prism structure, and the separation block at one corner is specifically used to strip the material roll to be separated. This triangular prism shape design allows the separation block to cut into the joint between the material rolls at a relatively sharp angle to achieve efficient stripping. At the same time, with the guidance of the first guide shaft on the stripping module to the stripped material, the entire stripping process is smoother and more stable, further improving the stripping efficiency and quality.

[0048] Embodiment 1

[0049] A three-layer roll stripping and pulling mechanism includes a back plate 10, on which a to-be-separated roll 1, a guide roller 2 and a reel 5 are mounted. The reel 5 is located on the back of the back plate 10 and is mounted with a second motor 14. The reel 5 is driven by the second motor 14 to reel in a target roll 101. The reel 5 is driven by the second motor 14 alone, so that the reel speed can be precisely controlled. In this way, the reel speed of the target roll 101 can be flexibly adjusted according to production requirements, so as to ensure the tightness and uniformity of the reel, and avoid problems such as loose rolls or wrinkles caused by too fast or too slow reeling speed. Moreover, the independent motor drive mode provides sufficient power for the winding process, ensuring the high efficiency of the winding operation, so that the entire mechanism can be applied to coils of different thicknesses and materials, improving the versatility and applicability of the equipment, and ensuring the quality of the final product. The winding shaft 5 is located below the material roll 1 to be separated, and the back plate 10 is located above the winding shaft 5 and is provided with a first pre-tightening block 4. A first guide block 3 is provided above the first pre-tightening block 4. The first guide block 3 is located at one end of the double-headed cylinder 6, and a second guide block 9 is provided at the end of the double-headed cylinder 6 away from the first guide block 3. A guide groove 302 is provided at the end of the first guide block 3 and the second guide block 9 away from the double-headed cylinder 6. A second guide shaft 301 is provided on the first guide block 3 and the second guide block 9. When the material roll 1 to be separated passes through the first guide block 3, the material roll 1 to be separated is guided to pass through the guide groove 302 by the second guide shaft 301. The coordinated use of the guide grooves 302 and the second guide shaft 301 on the first guide block 3 and the second guide block 9 provides a precise guiding path for the material roll 1 to be separated. When the material roll passes through the first guide block 3, the second guide shaft 301 guides the material roll into the guide groove 302, ensuring that the material roll can accurately move along the predetermined route in a complex transmission path, preventing the material roll from being offset, shaking or misaligned during operation, and laying a good foundation for subsequent peeling and winding operations. This precise guiding method helps to improve the working accuracy of the entire mechanism, reduce process errors caused by inaccurate material roll transmission, and improve product consistency and quality. Two stripping modules 11 are provided on the back plate 10 at one end of the double-headed cylinder 6 close to the second guide block 9, and the two stripping modules 11 are respectively above and below the double-headed cylinder 6. A second pre-tightening block 7 is provided on the back plate 10 below the double-headed cylinder 6. A first motor 12 is installed on the back plate 10, and the first motor 12, the material roll 1 to be separated, the first pre-tightening block 4 and the second pre-tightening block 7 are located on the back side of the back plate 10 and are all equipped with a transmission wheel 104. The first motor 12, the material roll 1 to be separated, the first pre-tightening block 4 and the second pre-tightening block 7 are connected by the transmission wheel 104 and the synchronous belt 13. The transmission connection mode of the synchronous belt 13 and the transmission wheel 104 realizes the power transmission between the first motor 12 and the material roll 1 to be separated, the first pre-tightening block 4 and the second pre-tightening block 7, which has the advantages of high transmission efficiency and smooth operation.This transmission method can ensure that all components keep running synchronously during the working process, reduce the tension change caused by the speed inconsistency between different components, avoid the problems of slipping, jamming or tearing of the roll during the transmission process, and also facilitate the power coordination and control of the whole system, which helps to improve the stability and reliability of the production process. In addition, since the synchronous belt 13 has a certain elasticity and buffering property, it can also reduce the mechanical impact between components to a certain extent and extend the service life of the equipment.

[0050] Embodiment 2

[0051] In order to separate the target material roll 101 from the second peeling layer 102 and the first separation layer 103, for example, Figures 1 to 6As shown, the present invention also includes: the material roll 1 to be separated is guided by the guide roller 2 to pass through the first pre-tightening block 4, the stripping module 11 above the first guide block 3 double-headed cylinder 6, the second guide block 9, the stripping module 11 below the double-headed cylinder 6 and the second pre-tightening block 7 in sequence, the first pre-tightening block 4 and the second pre-tightening block 7 are rotatably mounted with a fixed roller 405, the transmission wheels 104 of the first pre-tightening block 4 and the second pre-tightening block 7 are transmission-connected with the fixed roller 405, and a fixed frame 401 is movably mounted on one side of the fixed roller 405 in the first pre-tightening block 4 and the second pre-tightening block 7, and a movable roller 404 is rotatably mounted on the fixed frame 401, and the fixed roller 405 and the movable roller 404 are arranged on the first pre-tightening block 4 and the second pre-tightening block 7, so that the material roll 1 to be separated can be effectively pre-tightened and supported. The fixed roller 405 is a stable supporting component connected to the transmission wheel 104 to ensure the power transmission of the pre-tightening block, while the movable roller 404 can adjust its position according to the thickness and state of the material roll. They cooperate with each other to provide a stable transmission channel for the material roll, ensuring that the material roll maintains appropriate tension during the transmission process. This helps to avoid the material roll from being loose or too tight during the pre-tightening process, improves the transmission stability of the material roll, reduces the quality problems such as wrinkles and stretching deformation caused by uneven tension of the material roll, and ensures the smooth progress of subsequent stripping and winding operations. A threaded rod 403 is rotatably installed on the fixed frame 401, and the threaded rod 403 passes through the first pre-tightening block 4 or the second pre-tightening block 7, and the threaded rod 403 and the first pre-tightening block 4 or the second pre-tightening block 7 are transmitted by threaded engagement. A handle 402 is provided at the end of the threaded rod 403. The handle 402 drives the threaded rod 403 to rotate, thereby causing the fixed frame 401 to move forward and backward in the first pre-tightening block 4 or the second pre-tightening block 7, so that the first pre-tightening block 4 or the second pre-tightening block 7 clamps the material roll 1 to be separated through the movable roller 404 and the fixed roller 405. The threaded rod 403 is driven to rotate by the handle 402, and the fixed frame 401 is driven to move forward and backward by the threaded meshing transmission, so as to achieve precise adjustment of the distance between the movable roller 404 and the fixed roller 405, thereby achieving flexible clamping of the material roll 1 to be separated. The operator can easily adjust the clamping force by rotating the handle 402 according to the material rolls of different thicknesses and materials, so that the pre-tightening block can adapt to different working conditions.This manual adjustment method is simple and easy, does not require complicated tools and equipment, and can also ensure that the ideal pre-tightening effect can be achieved when processing different production batches or different specifications of rolls, thereby improving the adaptability of the equipment and the convenience of operation, and helping to improve the working efficiency and product quality of the entire mechanism. The roll 1 to be separated is stripped of the first separation layer 103 through the stripping module 11 above the double-headed cylinder 6, and the roll 1 to be separated is stripped of the second stripping layer 102 through the stripping module 11 below the double-headed cylinder 6. The stripping module 11 is in the shape of a triangular prism, and one corner of the stripping module 11 is provided with Separation block 1102, stripping module 11 is located behind separation block 1102 and at two outer corners of stripping module 11, receiving grooves 1103 are provided, and first guide shaft 1101 is rotatably installed in receiving groove 1103, and the separation block 1102 is used to strip the material roll 1 to be separated, and the separation block 1102 is used to guide the target material roll 101, the second stripping layer 102, and the first stripping layer 103 after stripping. The triangular prism-shaped stripping module 11 is designed, and its unique shape characteristics are utilized, and the separation block 1102 can effectively perform stripping operations on three layers of rolls. Separation block 1102 is located at a corner of stripping module 11, and can cut into the bonding layer of the material roll at a suitable angle, making the stripping process smoother and more efficient. The accommodating groove 1103 and the first guide shaft 1101 arranged behind the separation block 1102 and at the other two corners not only provide accommodating space for the layers of materials after peeling, but also can accurately guide them, avoiding the mutual entanglement or deviation of the predetermined trajectory between the layers of materials after peeling, ensuring that the layers of materials can continue to be transmitted in an orderly manner after peeling, improving the accuracy and quality of the peeling operation, and also facilitating subsequent processing and handling procedures.

[0052] Working principle:

[0053] The mechanism is mainly powered by a first motor 12 and a second motor 14. The first motor 12 is connected to the to-be-separated material roll 1, the first pre-tightening block 4 and the second pre-tightening block 7 through a transmission wheel 104 and a synchronous belt 13. The second motor 14 is installed on the back of the back plate 10 to drive the reel 5 to reel the target material roll 101.

[0054] This power transmission mode enables the various components of the entire mechanism to work in coordination. When the first motor 12 is started, the to-be-separated roll 1 begins to unwind, and at the same time the first pre-tightening block 4 and the second pre-tightening block 7 also start to work, providing power support for the transmission of the roll. The operation of the second motor 14 ensures that the target roll 101 can be rewound in a timely and effective manner.

[0055] The material roll 1 to be separated is guided by the guide roller 2 to ensure that the material roll can enter the subsequent processing link in a predetermined direction.

[0056] The material roll passes through the first pre-tightening block 4, and the fixed roller 405 and the movable roller 404 on the first pre-tightening block 4 play a certain supporting and pre-tightening role on the material roll 1 to be separated. Here, the movable roller 404 adjusts the distance with the fixed roller 405 by moving the fixed frame 401, so as to adapt to the material rolls of different thicknesses. The operator can drive the threaded rod 403 to rotate through the handle 402, so that the fixed frame 401 moves back and forth in the first pre-tightening block 4, and realizes the operation of clamping or loosening the material roll.

[0057] Next, the material roll reaches the first guide block 3. The first guide block 3 and the second guide block 9 are provided with a guide groove 302 at one end away from the double-head cylinder 6, and a second guide shaft 301. When the material roll 1 to be separated passes through the first guide block 3, the second guide shaft 301 guides the material roll 1 to be separated to pass through the guide groove 302, ensuring the accurate transmission path of the material roll.

[0058] After being guided, the to-be-separated material roll 1 continues to move forward and reaches the stripping module 11 above and below the double-headed cylinder 6. The stripping module 11 is in the shape of a triangular prism, with a separation block 1102 at one corner, and a receiving groove 1103 is provided behind the separation block 1102 and at the other two corners, and a first guide shaft 1101 is rotatably installed in the receiving groove 1103.

[0059] When the material roll contacts the stripping module 11 above the double-headed cylinder 6, the separation block 1102 cuts into the material roll and strips the first separation layer 103 from the material roll 1 to be separated. Similarly, when passing through the stripping module 11 below the double-headed cylinder 6, the separation block 1102 strips the second stripping layer 102. The stripped layers of material are guided by the first guide shaft 1101 to prevent them from being entangled with each other or deviating from the predetermined path.

[0060] After the stripping operation, the target roll 101 (i.e., the remaining part) continues to be transported, and after being guided by the second guide block 9, it passes through the second pre-tightening block 7 under the double-head cylinder 6. The working principle of the second pre-tightening block 7 is similar to that of the first pre-tightening block 4, and the fixed roller 405 and the movable roller 404 are used to clamp and pre-tighten the roll 1 to be separated, thereby ensuring the stability of the roll transmission.

[0061] Finally, the target material roll 101 is transferred to the reel 5, and the reel 5 is driven by the second motor 14 to reel up, thereby completing the peeling and reeling process of the entire three-layer roll.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0063] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
