[0002] Embedded sealing strips are sealing materials used to fill installation gaps and achieve functions such as sealing, dustproofing, waterproofing, and sound insulation. They are usually made of flexible materials such as rubber, PVC, and EPDM. The installation method is to embed the sealing strip into a pre-set groove or gap, and rely on its own elasticity or structural shape to fit tightly against the contact surface to form an effective seal. They are widely used in doors and windows, automobiles, mechanical equipment, electrical cabinets and other fields.

[0003] According to a public announcement (Announcement No.: CN211107254U) of a winding device for producing automotive sealing strips, the above application includes a base, a water tank is fixedly connected to the left side of the top of the base, a conduit is connected to the bottom of the right side of the water tank, a water outlet pipe is connected to the top of the right side of the water tank, a pressure pump is connected to the end of the conduit away from the water tank, a water inlet pipe is connected to the right side of the pressure pump, and a fixing rod is fixedly connected to the top of the base and to the right side of the pressure pump.

[0004] However, in actual use, the embedded sealing strip is not a standard circle in cross-section, which makes it easy to twist during winding. Twisting will cause permanent deformation of the sealing strip cross-section, affecting its tightness with the assembly structure, and thus reducing its sealing, waterproofing, and sound insulation performance. In view of this, we propose an embedded sealing strip winding device. Summary of the Invention

[0011] Preferably, the take-up roller is connected to the transmission rod, and a gear is fixedly connected to the end face of the transmission rod. The gear meshes with an external drive device, thereby causing the take-up roller to rotate and take up the sealing strip body.

[0012] Preferably, one end of the spring is fixedly connected to the inner bottom surface of the fixed box, and the other end of the spring is fixedly connected to the bottom end surface of the lower pressure plate.

[0013] Preferably, the reciprocating screw is rotatably connected to the frame, a pulley is fixedly connected to the side wall of the reciprocating screw, the pulley is connected to a belt drive, and a second pulley is fixedly connected to the side wall of the transmission rod, the second pulley is connected to a belt drive.

[0014] Preferably, a crossbar is fixedly connected to the inner wall of the frame, and the crossbar is slidably connected to the movable block. The crossbar ensures that the movable block can only reciprocate laterally along the reciprocating screw.

[0015] Preferably, a sealing ring is fixedly connected to the side wall of the bidirectional screw, and the sealing ring is drivenly connected to the inner wall of the movable block.

[0016] Compared with the prior art, the present invention provides an embedded sealing strip winding device, which has the following advantages:

[0017] 1. This embedded sealing strip winding device, through the set winding assembly, guides the sealing strip through the guide groove before it is wound by the winding roller. The guide path closely fits its cross-sectional contour, forcing it to maintain the correct posture and preventing winding deformation or indentation caused by abnormal posture. The clamping plates move towards each other, thus enabling the device to adapt to sealing strips of different sizes, widths, and heights. After the clamping plates are tightened, they can stabilize the position of the sealing strip during the guiding process, preventing it from shifting or tilting during high-speed movement. The lower pressure plate provides continuous and stable clamping force to prevent it from loosening, keeping the shape of the sealing strip compact and stable after winding, and ensuring that the overall winding shape is regular.

[0018] 2. The embedded sealing strip winding device, through the setting of the sealing ring, is embedded in the annular gap between the bidirectional screw and the movable block, which plays a role in gap compensation, effectively preventing the bidirectional screw from shaking or deviating during rotation, and at the same time moderately increasing the friction to prevent it from rotating unexpectedly.

[0026] As shown in Figures 1-6, this utility model provides a technical solution: an embedded sealing strip winding device, including a frame 1, a guide roller 2 rotatably connected to the inner wall of the frame 1, a transmission rod 3 rotatably connected to the side wall of the guide roller 2, and a winding assembly 4 provided on the inner wall of the frame 1. The winding assembly 4 includes a winding roller 401, a guard plate 402, a fixing box 403, a vertical rod 404, a lower pressure plate 405, a spring 406, a movable block 407, a guide groove 408, a chamfer 409, a bidirectional screw 410, a connecting frame 411, a clamping plate 412, and a reciprocating screw 413.

[0027] In one embodiment of this utility model, the take-up roller 401 is connected to the transmission rod 3. A guard plate 402 is fixedly connected to the side wall of the take-up roller 401. A fixed box 403 is fixedly connected to the outer wall of the guard plate 402. A vertical rod 404 is fixedly connected to the inner bottom surface of the fixed box 403. A lower pressure plate 405 is sleeved on the side wall of the vertical rod 404. A spring 406 is sleeved on the side wall of the vertical rod 404. One end of the spring 406 is fixedly connected to the inner bottom surface of the fixed box 403. The other end of the spring 406 is fixedly connected to the bottom end face of the lower pressure plate 405. A gear 10 is fixedly connected to the end face of the transmission rod 3. The gear 10 meshes with an external drive device, thereby causing the take-up roller 401 to rotate and take up the sealing strip body 6.

[0028] The reciprocating screw 413 is rotatably connected to the frame 1, and the movable block 407 is threadedly connected to the reciprocating screw 413. The side wall of the movable block 407 is provided with a guide groove 408, which is sleeved with the sealing strip body 6. The side wall of the guide groove 408 is provided with a chamfer 409. The side wall of the reciprocating screw 413 is fixedly connected with a pulley 1, which is connected to the belt 8 for transmission. The side wall of the transmission rod 3 is fixedly connected with a pulley 2, which is connected to the belt 8 for transmission.

[0029] The bidirectional screw 410 is sleeved with the movable block 407. The end face of the bidirectional screw 410 is provided with a slot 5. The side wall of the bidirectional screw 410 is threaded with a connecting frame 411. The side wall of the connecting frame 411 is fixedly connected with a clamping plate 412. The inner wall of the frame 1 is fixedly connected with a crossbar 9. The crossbar 9 is slidably connected with the movable block 407. Through the crossbar 9, the movable block 407 can only move laterally along the reciprocating screw 413.

[0030] The transmission rod 3 is rotated by the external transmission device, which in turn drives the take-up roller 401 to rotate. The take-up roller 401 takes up the sealing strip. The rotation of the transmission rod 3 drives the reciprocating screw 413 to rotate through the transmission of the belt 8, which in turn drives the movable block 407 to move laterally back and forth, guiding the sealing strip so that the sealing strip is evenly wrapped around the outer wall of the take-up roller 401, preventing material from being concentrated in a certain area and causing bulging or uneven tightness.

[0031] The guide groove 408 conforms to the shape of the sealing strip. Before the sealing strip is wound by the take-up roller 401, it passes through the guide groove 408. The guide path closely conforms to its cross-sectional contour, forcing it to maintain the correct posture and preventing entanglement, deformation or indentation caused by abnormal posture. By inserting a hex wrench into the slot 5, the reciprocating screw 413 is driven to rotate, causing the clamping plates 412 to move towards each other. This allows the device to adapt to sealing strips of different sizes, widths and heights. After the clamping plates 412 are clamped, the position of the sealing strip can be stabilized during the guiding process, preventing it from shifting or tilting during high-speed movement.

[0032] After the winding roller 401 winds up the sealing strip, the lower pressure plate 405, under the elastic action of the spring 406, makes the lower pressure plate 405 tightly abut against the sealing strip. The lower pressure plate 405 provides a continuous and stable clamping force to prevent it from loosening, keep the shape of the sealing strip compact and stable after winding, and ensure that the overall winding shape is regular, which is convenient for packaging and use.

[0033] In addition, a sealing ring 7 is fixedly connected to the side wall of the bidirectional screw 410. The sealing ring 7 is connected to the inner wall of the movable block 407. The sealing ring 7 is embedded in the annular gap between the bidirectional screw 410 and the movable block 407, which plays the role of gap compensation. This effectively prevents the bidirectional screw 410 from shaking or deviating during rotation, and at the same time moderately increases the friction to prevent it from rotating unexpectedly.

[0034] In this invention, during use, the take-up roller 401 winds up the sealing strip. The transmission rod 3 rotates, driving the reciprocating screw 413 to rotate via the belt 8, which in turn drives the movable block 407 to move laterally back and forth, guiding the sealing strip so that it is evenly wrapped around the outer wall of the take-up roller 401, preventing material from concentrating in a certain area. Before being wound by the take-up roller 401, the sealing strip passes through the guide groove 408, and the guide path closely fits its cross-sectional contour, forcing it to maintain the correct posture and preventing deformation or indentation caused by abnormal posture. By inserting a hexagonal wrench into the slot 5, the reciprocating screw 413 is driven to rotate, causing the clamping plates 412 to move towards each other, thus enabling the device to adapt to sealing strips of different sizes. After the take-up roller 401 finishes winding up the sealing strip, the lower pressure plate 405, under the elastic action of the spring 406, tightly abuts against the sealing strip, providing a continuous and stable clamping force to prevent it from loosening.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
