[0002] In the production process of materials such as Velcro, it is usually necessary to roll the finished continuous material into rolls for subsequent storage, transportation or further processing.

[0003] When existing strip winding devices are winding, as the diameter of the strip roll increases, loosening of the roll is likely to occur, affecting the uniformity and tightness of the winding. At the same time, in the cutting process after winding, the outer layer of the strip is still under tension, and the end of the strip is prone to lose tension and rebound, causing the strip to loosen, which is not conducive to the subsequent attaching process of the strip end. Utility Model Content

[0004] The purpose of this utility model is to provide a material strip winding device, which solves the above problems by setting a pressing structure that can press the outer surface of the material roll when the winding mechanism is winding and the shearing mechanism is performing the shearing action.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown, this utility model discloses a material strip winding device, including a frame 1. The frame 1 is provided with a winding mechanism 2 that can drive the material strip to rotate so as to wind it into a material roll, a feeding mechanism 3 for transferring the material strip to the winding mechanism 2, a cutting mechanism 4, and an attaching mechanism 5 for attaching and fixing the material strip at the end of the material roll. A pressure arm 61 is slidably connected to the frame 1. A pressure roller assembly 62 is rotatably connected to one end of the pressure arm 61 near the winding mechanism 2. A first driving device 63 is also provided between the frame 1 and the pressure arm 61, which can drive the pressure arm 61 to press the pressure roller assembly 62 against the outer surface of the material roll when the winding mechanism 2 is winding and the cutting mechanism 4 is cutting.

[0024] like Figure 1 and Figure 2As shown, in this embodiment, the winding mechanism 2 is mounted on the frame 1 and rotates to wind a continuous strip of material to form an ever-growing roll. The feeding mechanism 3 is located upstream of the winding mechanism 2 and transfers the strip to the winding position of the winding mechanism 2. The cutting mechanism 4 can be implemented using pneumatic shears, mechanical cutters, etc., and cuts the strip upon receiving a control signal. After winding is completed, the cutting mechanism 4 performs a cutting action to cut the strip into individual rolls. To prevent the ends of the cut rolls from unraveling, the attaching mechanism 5 preferably uses an adhesive tape applicator that includes tape supply, cutting, and pressing components to adhere and fix the ends of the strip to the surface of the roll. The first drive device 63 is connected between the frame 1 and the pressing arm 61. The first drive device 63 can be implemented by means of a cylinder, hydraulic cylinder, electric push rod or servo motor with lead screw mechanism, etc. The first drive device 63 provides driving force to drive the pressing arm 61 to move. One end of the pressing arm 61 is close to the winding mechanism 2 and is rotatably connected to the pressure roller assembly 62 through a rotating shaft. The pressure roller assembly 62 contacts the outer circumference of the material roll being formed to achieve the pressing effect.

[0025] During the winding process, the diameter of the material roll gradually increases as the material strip continues to wind. To ensure that the pressure roller assembly 62 on the pressure arm 61 maintains stable contact with the surface of the material roll and applies appropriate pressure, the controller can estimate the current diameter of the material roll based on the functional relationship between the rotation speed of the winding mechanism 2, the winding time, and the diameter of the material roll during winding, and control the action of the first drive device 63 accordingly. Alternatively, a non-contact distance sensor can be installed on the pressure arm 61 to measure the relative position between the pressure roller assembly 62 and the surface of the material roll to control the action of the first drive device 63. Through these methods, the position of the pressure arm 61 can be dynamically adjusted so that it retracts accordingly as the diameter of the material roll increases.

[0026] The specific working principle of one embodiment of the tape winding device is as follows: The feeding mechanism 3 pulls the free end of the tape into the winding mechanism 2. Then, the winding mechanism 2 starts, and the first driving device 63 pushes the pressure arm 61 close to the tape roll, so that the outer peripheral surface of the pressure roller assembly 62 located at the front end of the pressure arm 61 presses against the outer peripheral surface of the tape roll and applies a preset radial pressure to the tape roll. During the continuous rotation of the winding mechanism 2 for winding, the diameter of the tape roll gradually increases as the tape is continuously wound. The first driving device 63 drives the pressure roller assembly 62 to move away from the tape roll simultaneously, while pressing the pressure roller assembly 62 tightly against the outer peripheral surface of the tape roll, thereby ensuring the tightness of the tape roll winding. When the tape in the tape roll on the winding mechanism 2 reaches a predetermined length or the tape roll reaches a predetermined diameter, the first driving device 63 operates to keep the pressure roller assembly 62 pressing against the outer peripheral surface of the tape roll. Then, the shearing mechanism 4 cuts the tape to prevent the tape roll from loosening due to the elastic rebound of the tape. Then, the attaching mechanism 5 starts. One end of the tape is attached to the end of the outermost layer of the material roll. After the winding mechanism 2 rotates slightly, the attaching mechanism 5 attaches the other end of the tape to the surface of the material roll. Finally, the material roll is unloaded, thus completing a complete winding cycle.

[0027] The first drive device 63 drives the pressure arm 61, so that the pressure roller assembly 62 continuously presses the outer surface of the material roll throughout the winding process, ensuring tight adhesion between the material strip layers. This solves the problem of loose winding caused by the increase in roll diameter and improves the tightness of winding. At the same time, when the shearing mechanism 4 performs the shearing action, the first drive device 63 still remains in working state, and the pressure roller assembly 62 continues to press the material roll, limiting the springback and slack of the material strip and improving the reliability of adhesion.

[0028] The first driving device 63 includes a cylinder body 631 fixedly connected to the frame 1 and an output shaft 632 that can extend axially along the cylinder body 631. The end of the output shaft 632 is connected to the pressing arm 61, and the extension and retraction direction of the output shaft 632 is arranged radially along the rotation center of the winding mechanism 2 to drive the pressing arm 61 to move in that radial direction. When air enters the cylinder body 631, it pushes the output shaft 632 to extend outward along its axial direction, thereby driving the pressing arm 61 to move axially and causing the pressure roller assembly 62 at its front end to press radially against the outer peripheral surface of the material roll. The structure is simple and has high stability.

[0029] The pressure arm 61 is provided with a pressure roller shaft 611 at one end near the winding mechanism 2. The pressure roller assembly 62 includes a material roll pressure roller 621 rotatably connected to the pressure roller shaft 611. A material roll pressure plate 622 for limiting the axial displacement of the material strip during the winding process is sleeved and fixed on the material roll pressure roller 621.

[0030] The pressure roller shaft 611 can be integrally formed with the end of the pressure arm 61, or it can be a separate shaft fixedly connected to the pressure arm 61 by means of threads, welding, etc. The axial direction of the pressure roller shaft 611 is perpendicular to the length direction of the pressure arm 61. The coil pressure roller 621 is a cylindrical roller with a through shaft hole in its center, allowing the coil pressure roller 621 to rotate around the axis of the pressure roller shaft 611. When the outer circumferential surface of the coil pressure roller 621 contacts the outer circumference of the rotating coil, the coil pressure roller 621 can apply radial clamping force to the coil while avoiding sliding friction with the surface of the material strip, preventing the material strip from being scratched or stretched and deformed. Since the coil is formed by winding layer by layer on the winding mechanism 2, its axial position tends to move slightly. The coil pressure plate 622 is sleeved on the outer circumference of the coil pressure roller 621 and fixedly connected to the coil pressure roller 621. The surface of the coil pressure plate 622 is perpendicular to the axis of the pressure roller shaft 611. When the pressure roller assembly 62 presses against the coil, the surface of the coil pressure plate 622 abuts against the axial end face of the coil. The abutment of the coil pressure plate 622 forms an axial mechanical limit, which restricts the axial displacement of the strip during the winding process, ensures that the strip is kept in the predetermined axial position during winding, and improves the winding quality.

[0031] The frame 1 is connected to a telescopic rod 71. The front end of the telescopic rod 71 is provided with a connecting block 72. The connecting block 72 extends radially along the rotation center of the winding mechanism 2 to the front of the material roll with a pressure shaft 73. The pressure shaft 73 is rotatably connected to a pressure cylinder 74 for limiting the axial displacement of the material strip. The telescopic rod 71 is connected to a second drive device 75 that can drive it to move in the front-back direction.

[0032] A connecting block 72 is provided at the front end of the telescopic rod 71, and one end of the pressure shaft 73 is fixedly connected to the connecting block 72. The pressure shaft 73 extends radially along the rotation center of the winding mechanism 2, and a pressure cylinder 74 is rotatably connected to the pressure shaft 73 to prevent sliding friction from damaging the material strip. The side wall of the pressure cylinder 74 abuts against the axial side of the material strip, so that the pressure cylinder 74 acts as an axial baffle, further restricting the axial displacement of the material strip away from the core center during the winding process, ensuring that the material strip is stacked to form a material roll with a flat end face. The second drive device 75 can be implemented by means of a cylinder or hydraulic cylinder, etc. The second drive device 75 is connected to the telescopic rod 71 and can drive the telescopic rod 71 to move in the front and back direction. When it is necessary to perform avoidance operations such as loading, removing finished material rolls, or handling abnormalities, the second drive device 75 can drive the telescopic rod 71 to move forward to make room for operation.

[0033] The winding mechanism 2 includes a winding shaft 21, which is connected to a third driving device 22 capable of driving the winding shaft 21 to rotate. The end of the winding shaft 21 has a feed groove 211.

[0034] The roll 21 serves as the base for the material strip winding, and its end face or outer peripheral surface has an inlet groove 211. The feeding mechanism 3 can insert the free end of the material strip into the inlet groove 211, and perform preliminary positioning and clamping of the material strip head through the inlet groove 211 to achieve stable winding. The third drive device 22 is connected to the roll 21. In this embodiment, the third drive device 22 includes a motor, the output end of which is connected to a drive pulley, and the roll 21 is provided with a driven pulley. The roll 21 is driven to rotate through a belt or synchronous belt. The rotational power provided by the third drive device 22 drives the roll 21 to rotate continuously around its own axis, thereby driving the material strip to wind into a roll.

[0035] The feeding mechanism 3 includes a movable frame 31, which is connected to a fourth driving device 34 that can drive it to move in the left and right direction. The lower part of the movable frame 31 is provided with a mounting base 32, and the mounting base 32 is provided with a pneumatic finger 33 for clamping the material strip and moving with the movable frame 31 to feed it into the feed trough 211.

[0036] In this embodiment, the fourth drive device 34 is a KK module. The fourth drive device 34 drives the moving frame 31 to reciprocate linearly in the left-right direction, thereby transporting the material strip from the pick-up point to the inlet point. The pneumatic finger 33 is a conventional pneumatic actuator, comprising a fixed base and multiple relatively openable and closable gripping fingers. It is connected to an air source and a solenoid valve via an air pipe. The gripping fingers open or close by controlling the flow of compressed air. The opening and closing direction of the pneumatic finger 33 is perpendicular to the moving direction, and the pneumatic finger 33 is mounted on a mounting base 32 at the lower part of the moving frame 31, thereby clamping and releasing the material strip.

[0037] The frame 1 is provided with a support rod 81, and the support rod 81 is slidably connected to a mounting plate 82. The roll shaft 21 is fixedly connected to the mounting plate 82. The frame 1 is also provided with a lead screw 83 arranged in the front-back direction. The lead screw 83 is connected to a fifth drive device 84. The mounting plate 82 is provided with a lead screw nut 85 that cooperates with the lead screw 83.

[0038] In this embodiment, the mounting plate 82 has through holes that match the support rod 81, thus allowing it to slide on the support rod 81. The winding shaft 21 is fixedly connected to the mounting plate 82, so that when the mounting plate 82 slides along the support rod 81, the winding shaft 21 moves synchronously with the mounting plate 82. A lead screw 83 is provided on the frame 1 along the front-to-back direction. A fifth drive device 84 is connected to one end of the lead screw 83 to provide rotational power to drive the lead screw 83 to rotate around its own axis. A lead screw nut 85 is fixedly connected to the mounting plate 82, and the internal thread of the lead screw nut 85 meshes with the external thread of the lead screw 83. When the lead screw 83 rotates under the drive of the fifth drive device 84, the rotational motion of the lead screw 83 is converted into linear movement of the lead screw nut 85 along with the mounting plate 82, which is fixed to it, along the axis of the lead screw 83, thereby driving the winding shaft 21 to move along the front-to-back direction. In this embodiment, a discharge baffle is provided below the winding mechanism 2, inclined in the left-to-right direction. After the attaching mechanism 5 completes the attaching, the fifth drive device 84 drives the lead screw 83 to move the roll shaft 21 backward, so that the roll loses the support of the roll shaft 21 and moves downward under the action of gravity and falls onto the discharge baffle, and rolls with the discharge baffle to the next process.

[0039] The attaching mechanism 5 includes an attaching plate 51, on which a tape roll 52 is provided. The free end of the tape roll 52 extends to the lower part of the attaching plate 51. The attaching plate 51 is connected to a sixth driving device 53 that can drive the attaching plate 51 to move in the radial direction along the rotation center of the roll mechanism 2, thereby moving it closer to or away from the roll. The attaching plate 51 is also provided with a cutting mechanism 54 for cutting the tape.

[0040] In this embodiment, the tape roll 52 includes a core and tape wound around the core. The tape roll 52 can be rotatably connected to the attachment plate 51 via a central shaft or other means, allowing it to rotate freely and thus smoothly unwind the tape. The free end of the tape extends from the tape roll 52 to the lower part of the attachment plate 51. A sixth drive device 53 is connected between the attachment plate 51 and the frame 1 to drive the attachment plate 51 to move radially along the rotation center of the winding mechanism 2, thereby causing the free end of the tape at the lower part of the attachment plate 51 to contact the outermost end of the tape in the roll. In this embodiment, the cutting mechanism 54 includes a cylinder, the output end of which is connected to a blade. The cylinder drives the blade to cut the tape.

[0041] An auxiliary pressure roller 91 is provided between the shearing mechanism 4 and the winding mechanism 2. The auxiliary pressure roller 91 is connected to a seventh driving device 92 that can drive the auxiliary pressure roller 91 to move in the vertical direction. In this embodiment, the seventh driving device 92 is a cylinder. The cylinder drives the auxiliary pressure roller 91 to move in the vertical direction. During the winding process, the seventh driving device 92 drives the auxiliary pressure roller 91 to a high position and maintains a gap with the material strip to ensure that the material strip is smoothly transmitted under the control of the winding mechanism 2. Before the shearing mechanism 4 performs the shearing action, the seventh driving device 92 drives the auxiliary pressure roller 91 to move downward, so that the auxiliary pressure roller 91 keeps the material strip in a pressed state, thereby reducing the shaking of the material strip during shearing and improving the shearing quality.

[0042] The feeding side of the shearing mechanism 4 is provided with two opposing pressing cylinders 101. The piston rods of the two pressing cylinders 101 are connected to pressing blocks 102 for pressing the strip. The pressing cylinders 101 drive the pressing blocks 102 to clamp and fix the free end of the strip on the feeding side to prevent it from elastically rebounding, and to provide a stable reference position for the feeding mechanism 3 to clamp the free end of the strip in the next winding cycle.
