Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a sealing strip winding machine. Background Technology

[0002] In the field of sealing strip production, automated winding equipment is widely used in the winding and collection processes of sealing strips to improve production efficiency and reduce manual intervention. Currently, common automated sealing strip winding machines mainly rely on simple traction and winding mechanisms, enabling basic feeding and winding functions. However, due to the diversity of sealing strip materials (such as different cross-sections, sizes, hardness, and resilience characteristics), existing equipment has significant limitations when handling sealing strips of different specifications. Specifically, existing winding machines often cannot adapt to the automatic feeding requirements of sealing strips, and problems such as uneven layer thickness, inconsistent direction, or improper tension easily occur during the winding process, leading to defects such as collapse, knotting, or curling edges in the coiled products, affecting subsequent production processes. Furthermore, existing models lack precise automatic cutting functions after winding a specified layer thickness, have inaccurate exit space positioning, and insufficient capacity to handle double-exit products (with consistent left and right directions), especially during high-speed reciprocating winding, where automatic speed adjustment is impossible. These problems not only reduce the versatility and stability of the equipment but also increase operational complexity and maintenance costs, failing to meet customers' requirements for high efficiency, precision, and adaptability to multiple specifications. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a sealing strip winding machine.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model provides a sealing strip winding machine, including: a frame, a Y-axis drive mechanism mounted on the frame, a Z-axis drive mechanism mounted on the output end of the Y-axis drive mechanism, a feeding and traction assembly and a cutting assembly mounted on the output end of the Z-axis drive mechanism, and a winding assembly mounted on the frame and located next to the Y-axis drive mechanism. The feeding and traction assembly includes, in sequence, a guide traction assembly, a traction drive mechanism, and a guide groove along the conveying direction of the sealing strip. The cutting assembly is disposed between the traction drive mechanism and the guide groove and is used to cut the sealing strip. The sealing strip is sequentially guided by the guide traction assembly and the traction drive mechanism, and under the linkage adjustment of the Y-axis drive mechanism and the Z-axis drive mechanism, it is output through the guide groove to the winding assembly to complete the coiling.

[0005] Preferably, the feeding traction assembly further includes a fixing plate, and the guiding traction assembly, traction drive mechanism, cutting assembly, and guide groove are all fixed on the fixing plate.

[0023] Reference Figures 1 to 4 This utility model provides a sealing strip winding machine, including: a frame, a Y-axis drive mechanism 1 mounted on the frame, a Z-axis drive mechanism 2 mounted on the output end of the Y-axis drive mechanism 1, a feeding traction assembly 3 and a cutting assembly 4 mounted on the output end of the Z-axis drive mechanism 2, and a winding assembly 6 mounted on the frame and located next to the Y-axis drive mechanism 1. The Y-axis drive mechanism 1 enables horizontal fine-tuning along the Y-axis direction, used for left-right centering and entry line calibration of the sealing strip at the winding position; the Z-axis drive mechanism 2 enables height fine-tuning along the Z-axis direction, linked with the Y-axis, to precisely control the entry angle and height of the sealing strip at the winding entrance, reducing interlayer warping and misalignment.

[0024] The feeding traction assembly 3 includes, in sequence along the conveying direction of the sealing strip, a guide traction assembly, a traction drive mechanism, and a guide groove 5. The cutting assembly 4 is disposed between the traction drive mechanism and the guide groove 5 and is used to cut the sealing strip. The sealing strip is sequentially guided by the guide traction assembly and the traction drive mechanism, and under the linkage adjustment of the Y-axis drive mechanism 1 and the Z-axis drive mechanism 2, it is output through the guide groove 5 to the winding assembly 6 to complete the winding.

[0025] Furthermore, the feeding traction assembly 3 also includes a fixed plate 301. The guide traction assembly, traction drive mechanism, cutting assembly 4, and guide groove 5 are all fixed on the fixed plate 301. The fixed plate 301 is located at the output end of the Z-axis drive mechanism 2.

[0026] Furthermore, the guiding and traction assembly includes a first fixed guide wheel 302, a floating guide assembly, and a second fixed guide wheel 305; the first fixed guide wheel 302 is disposed at one end of the fixed plate 301; the floating guide assembly is disposed on the lower side of the fixed plate; the second fixed guide wheel 305 is disposed on the fixed plate 301; the floating guide assembly includes a sliding guide rail 303 fixed to the lower side of the fixed plate and a floating guide wheel 304 slidably connected to the sliding guide rail 303; the floating guide wheel 304 cooperates with the first fixed guide wheel 302 and the second fixed guide wheel 305 to form an adjustable tension structure to adapt to the feeding tension of sealing strips of different specifications; wherein, the first fixed guide wheel 302 is responsible for guiding and initial orientation; the floating guide wheel 304 provides variable compression; the second fixed guide wheel 305 performs strip shaping and posture stabilization, so that the sealing strip forms a stable traveling posture before being pulled into the guide groove. The floating guide wheel 304 can reciprocate on the sliding guide rail, and together with the first fixed guide wheel 301 and the second fixed guide wheel 305, it forms a continuously adjustable tension, which can maintain a suitable tension for sealing strips of different widths, thicknesses, hardnesses and rebounds, and avoid arching due to being too loose or stretching and deforming due to being too tight.

[0027] Furthermore, the traction drive mechanism includes a traction drive motor 306, a drive wheel 307 connected to the output end of the traction drive motor 306, a driven gear 308 meshing with the drive wheel 307, a traction wheel 309 coaxially connected to the driven gear 308, and a pressure wheel 310 disposed opposite to the traction wheel 309. In this embodiment, the working principle of the traction drive mechanism is as follows: the traction drive motor 306 drives the drive wheel 307 to move, thereby driving the driven gear 308 and the traction wheel 309 to move. The sealing strip forms a clamping contact area between the traction wheel 309 and the pressure wheel 310, so that the sealing strip generates sufficient friction with the outer periphery of the traction wheel 309 and is pulled out without slippage.

[0028] Furthermore, the cutting assembly 4 includes a cutting cylinder and a cutting blade disposed at the output end of the cutting cylinder. The working principle of the cutting assembly is as follows: the cutting cylinder drives the cutting blade to cut the sealing strip.

[0029] Furthermore, the winding assembly 6 includes a winding drive motor 601, a take-up turntable 602 connected to the output end of the winding drive motor 601, and a product tray 603 disposed on the take-up turntable 602. In this embodiment, the working principle of the winding drive motor is as follows: the winding drive motor 601 works to drive the take-up turntable 602, thereby driving the product tray 603 to rotate, so that the sealing strip from the guide groove 5 is wound on the take-up cylinder guide of the product tray.

[0030] Furthermore, the Y-axis drive mechanism 1 and the Z-axis drive mechanism 2 are linear modules or lead screw slides arranged orthogonally to each other. The Z-axis drive mechanism 2 is arranged on the output end of the Y-axis drive mechanism 1 to realize the linkage fine adjustment of the winding entrance in the two-dimensional directions of the Y-axis and Z-axis. In this embodiment, the Y-axis drive mechanism 1 works, thereby driving the Z-axis drive mechanism 2 to move along the Y-axis to realize the Y-axis adjustment of the winding entrance. The Z-axis drive mechanism 2 drives the feeding traction component 3 and the cutting component 4 installed on the Z-axis drive mechanism 2 to move along the Z-axis, thereby precisely adjusting the height of the sealing strip entering the winding entrance to realize the linkage fine adjustment of the winding entrance in the two-dimensional directions of the Y-axis and Z-axis.

[0031] Furthermore, the sealing strip winding machine also includes a sensor (not shown in the figure), which is installed on the winding turntable 602 to sense the number of layers of the sealing strip being wound. When the set target number of layers is reached and the threshold is approached, the traction drive motor 306 can be automatically controlled by the PLC controller 7 to enter pre-deceleration. After reaching the threshold, the cutting cylinder is controlled to work to accurately cut the sealing strip. The sensor is an incremental rotary encoder, which is installed on the drive shaft of the winding turntable.

[0032] Furthermore, the sealing strip winding machine also includes a PLC controller 7 mounted on the frame; the corresponding terminals of the PLC controller 7 are electrically connected to the corresponding terminals of the sensor, the winding drive motor 601, the cutting cylinder, the traction drive motor 306, the Y-axis drive mechanism 1, and the Z-axis drive mechanism 2. In this embodiment, the PLC controller 7 controls the Y-axis drive mechanism 1 and the Z-axis drive mechanism 2 to operate, aligning the outlet of the guide groove 5 with the winding inlet; then it controls the start / stop and speed of the traction drive motor 306, so that the traction wheel 306 outputs a stable linear speed that matches the winding speed; simultaneously, it controls the winding drive motor 601 to operate, driving the winding turntable 602 and the product tray 603 to rotate for material take-up; when the sensor feeds back information indicating that the target number of layers is approaching, the PLC controller 7 controls the traction drive motor 306 and the winding drive motor 601 to reduce their speed; when the sensor determines that the set number of layers has been reached, the PLC controls the cutting cylinder to operate, automatically cutting the sealing strip.

[0033] The working principle of this utility model: The sealing strip is guided sequentially from the feed end through the first fixed guide wheel 302, the floating guide wheel 304, and the second fixed guide wheel 305. After entering the clamping area of ​​the traction wheel 309 and the pressing wheel 310, it continues to pass through the guide groove 5. The PLC controller 7 controls the Y-axis drive mechanism 1 and the Z-axis drive mechanism 2 to work, adjusting the outlet of the guide groove 5 in the Y-axis and Z-axis directions to align with the winding inlet, so that the sealing strip stably enters the winding position where the product tray is located. Subsequently, the traction drive motor 306 is controlled to output a stable linear speed for feeding, and the winding drive motor 601 is controlled to drive the winding turntable 602 and the product tray 603 to rotate to complete the winding. The sensor feeds back the winding progress to the PLC controller 7: when the sensor feeds back information that the target number of layers is approaching, the PLC controller 7 controls the traction drive motor 306 and the winding drive motor 601 to reduce their speed. When the set number of layers is reached, the PLC controller 7 controls the cutting cylinder to act, completing the automatic cutting of the sealing strip, thereby ending this winding cycle.
