Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a winding device for nonwoven fabric processing with adjustable transmission tension. Background Technology
[0002] Nonwoven fabric processing refers to various processing methods applied to nonwoven fabrics to change their properties and uses. Common nonwoven fabric processing methods include printing, lamination, composite, and hot pressing to meet the needs of different fields, such as medical and health care, household goods, and clothing. In the processing, the winding machine is one of the key pieces of equipment. Its function is to wind up and arrange the processed nonwoven fabric, thus preparing it for subsequent processing and use. It is used to wind up the processed nonwoven fabric into a roll shape for subsequent transportation, storage, and use.
[0003] Existing nonwoven fabric processing winding equipment mostly controls tension by adjusting the conveying angle of the nonwoven fabric through the translation of two tension rollers. However, the translation distance of the two tension rollers does not change synchronously with the increase in tension, resulting in obvious tension peaks or valleys. This leads to material stretching deformation or relaxation, producing wrinkles, frayed edges, or even breaking or deforming the nonwoven fabric, affecting subsequent transportation, storage, and unwinding. Furthermore, a sufficiently long travel space needs to be reserved for the movement of the tension rollers, increasing the overall size and weight of the equipment. At the same time, before the wound nonwoven fabric rolls are transferred for transportation, manual assistance is required to separate the winding rollers from the winding frame, consuming a lot of time. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a winding device for nonwoven fabric processing with adjustable transmission tension.
[0005] This utility model is achieved by the following technical solution: a nonwoven fabric processing winding device with adjustable transmission tension, including support legs, winding table, tensioning mechanism, winding mechanism, first mounting frame, first guide roller, second mounting frame and second guide roller; A winding table is fixedly connected to the top of the support leg. A tensioning mechanism is provided on the top of the winding table. A winding mechanism is provided on the top of the winding table. A first mounting frame is fixedly connected to the top of the winding table. A first guide roller is rotatably connected to the inner wall of the first mounting frame. A second mounting frame is fixedly connected to the top of the winding table. A second guide roller is rotatably connected to the inner wall of the second mounting frame. The tensioning mechanism includes a tensioning frame, an active turntable, a driven turntable, a gear ring, gears, a tensioning motor, a first fixed frame, and a tensioning roller; The inner wall of the tensioning frame is rotatably connected to a drive turntable, and the inner wall of the tensioning frame is rotatably connected to a driven turntable. A gear ring is fixedly connected to the end of the drive turntable away from the tensioning frame. A gear meshes with the tooth surface of the gear ring. A tensioning motor is fixedly connected to the end of the gear away from the drive turntable. A first fixing frame is fixedly connected to the surface of the tensioning motor. A tensioning roller is rotatably connected to the inner wall of the drive turntable.
[0006] Through the above technical solution, by setting a driven turntable and an active turntable, tension adjustment is achieved by the active turntable rotating in the tensioning frame, which improves the space utilization of the device. At the same time, the rotation structure has a more stable motion trajectory than the translation structure, reducing structural wear and extending service life. By setting a gear ring and gears, the gear ratio between the gear ring and gears increases the transmission ratio of the tensioning motor, increases the output torque, and achieves precise angle control. By controlling the rotation angle of the active turntable, the swing position of the tensioning roller is controlled, and the wrapping angle and stroke path of the nonwoven fabric are adjusted, thus achieving precise and stepless adjustment of the nonwoven fabric tension.
[0007] As a further improvement to the above solution, the bottom of the tensioning frame is fixedly connected to the top of the winding table, and the bottom of the first fixing frame is fixedly connected to the surface of the tensioning frame.
[0008] As a further improvement to the above scheme, the end of the tensioning roller away from the active turntable is rotatably connected to the inner wall of the driven turntable, and two tensioning rollers are provided, symmetrically arranged on the inner wall of the active turntable.
[0009] As a further improvement to the above solution, the winding mechanism includes a lifting frame, a U-shaped groove, a bearing, a winding roller, a docking block, a docking seat, a motor, a rotating frame, a second fixed frame, a slider, a slide plate, a hydraulic push rod, a hydraulic pump, and a support frame. The top of the lifting frame has a U-shaped groove, the inner wall of which is slidably connected to a bearing, and the inner wall of which is slidably connected to a take-up roller. One end of the take-up roller is fixedly connected to a docking block, and the surface of the docking block is slidably connected to a docking seat. The end of the docking seat away from the docking block is fixedly connected to a motor, and the surface of the docking seat is rotatably connected to a rotating frame. The surface of the motor is fixedly connected to a second fixed frame, and the bottom of the rotating frame is fixedly connected to a slider. The surface of the take-up table is fixedly connected to a sliding groove plate, and the inner wall of the take-up table is fixedly connected to a hydraulic push rod. The input end of the hydraulic push rod is fixedly connected to a hydraulic pump, and the bottom of the hydraulic pump is fixedly connected to a support frame.
[0010] As a further improvement to the above solution, the bottom of the lifting frame is fixedly connected to the top of the winding table, and the top of the support frame is fixedly connected to the bottom of the winding table.
[0011] The above technical solution, by setting up a lifting frame, drives the take-up roller to rise as the diameter of the nonwoven fabric roll increases, avoiding friction between the nonwoven fabric and the take-up table and improving the practicality of the device.
[0012] As a further improvement to the above solution, the bottom of the second fixed frame is fixedly connected to the surface of the rotating frame.
[0013] As a further improvement to the above solution, the surface of the slider is slidably connected to the inner wall of the winding table, the surface of the slider is slidably connected to the inner wall of the slide plate, and the output end of the hydraulic push rod is fixedly connected to the surface of the slider.
[0014] The above technical solution involves setting up a slider, which is then pushed by a hydraulic pusher to slide in a slide plate. This causes the motor and docking seat to move horizontally and dock with the docking block at one end of the take-up roller. The motor then drives the take-up roller to rotate and perform take-up. Once take-up is complete, the hydraulic pusher drives the slider to slide, separating the docking seat from the docking block. This facilitates the handling and transfer of the take-up roller, reduces human intervention, and improves transfer efficiency.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a tensioning mechanism, specifically a gear ring and gears. By adjusting the gear ratio between the gear ring and gears, the transmission ratio of the tensioning motor is increased, thereby increasing the output torque and achieving precise angle control. This controls the rotation angle of the active turntable, which in turn controls the swing position of the tensioning roller, adjusting the wrapping angle and travel path of the nonwoven fabric. This enables precise and stepless adjustment of the nonwoven fabric tension. By setting a driven turntable and an active turntable, tension adjustment is achieved by the active turntable rotating within the tensioning frame. This improves the space utilization of the device. Furthermore, the rotating structure provides a more stable motion trajectory compared to a translational structure, reducing structural wear and extending service life.
[0016] This invention features a winding mechanism, specifically a lifting frame. As the diameter of the nonwoven fabric roll increases, the winding roller rises, preventing friction between the nonwoven fabric and the winding table and improving the device's practicality. A slider is installed, and a hydraulic pusher pushes the slider to slide within a chute, causing the motor and docking seat to move horizontally and engage with a docking block at one end of the winding roller. This allows the motor to drive the winding roller to rotate and wind it up. Once winding is complete, the hydraulic pusher causes the slider to slide, separating the docking seat from the docking block, facilitating the handling and transfer of the winding roller, reducing human intervention, and improving transfer efficiency.

Tension adjustment is achieved by the rotation of the drive turntable 302 within the tensioning frame 301, improving the space utilization of the device.

Gears 305 mesh with the teeth of the gear ring 304, and gear 305 is furthest from the drive turntable 302. A tensioning motor 306 is fixedly connected to one end. By increasing the gear ratio between the gear ring 304 and the gear 305, the transmission ratio of the tensioning motor 306 is increased, the output torque is increased, and precise angle control is achieved. The rotation angle of the active turntable 302 is controlled, thereby controlling the swing position of the tensioning roller 308, adjusting the wrapping angle and travel path of the nonwoven fabric, and achieving precise and stepless adjustment of the tension of the nonwoven fabric.

[0023] The winding mechanism 4 includes a lifting frame 401, a U-shaped groove 402, a bearing 403, a winding roller 404, a docking block 405, a docking seat 406, a motor 407, a rotating frame 408, a second fixed frame 409, a slider 410, a slide plate 411, a hydraulic push rod 412, a hydraulic pump 413, and a support frame 414. The top of the lifting frame 401 is provided with a U-shaped groove 402. A bearing 403 is slidably connected to the inner wall of the U-shaped groove 402. A take-up roller 404 is slidably connected to the inner wall of the bearing 403. A docking block 405 is fixedly connected to one end of the take-up roller 404. A docking seat 406 is slidably connected to the surface of the docking block 405. A motor 407 is fixedly connected to the end of the docking seat 406 away from the docking block 405. A rotating frame 408 is rotatably connected to the surface of the docking seat 406. A second fixed frame 409 is fixedly connected to the surface of the motor 407.

A hydraulic push rod 412 is fixedly connected to the inner wall of the take-up table 2. A hydraulic pump 413 is fixedly connected to the input end of the hydraulic push rod 412. A support frame 414 is fixedly connected to the bottom of the hydraulic pump 413.
[0024] The bottom of the lifting frame 401 is fixedly connected to the top of the winding table 2. As the diameter of the nonwoven fabric roll increases, the winding roller 404 rises, avoiding friction between the nonwoven fabric and the winding table 2 and improving the practicality of the device. The top of the support frame 414 is fixedly connected to the bottom of the winding table 2.
[0025] The bottom of the second fixed bracket 409 is fixedly connected to the surface of the rotating bracket 408.
[0026] The surface of slider 410 is slidably connected to the inner wall of take-up table 2, and the surface of slider 410 is slidably connected to the inner wall of slide plate 411. The output end of hydraulic push rod 412 is fixedly connected to the surface of slider 410. Hydraulic push rod 412 pushes slider 410 to slide in slide plate 411, driving motor 407 and docking seat 406 to move horizontally and dock with docking block 405 at one end of take-up roller 404, so that motor 407 drives take-up roller 404 to rotate for take-up. After take-up is completed, hydraulic push rod 412 drives slider 410 to slide so that docking seat 406 separates from docking block 405, which facilitates the handling and transfer of take-up roller 404, reduces human intervention, and improves transfer efficiency.
[0027] The implementation principle of the adjustable transmission tension nonwoven fabric winding device in this application embodiment is as follows: Before use, the hydraulic push rod 412 pushes the slider 410 to slide in the slide plate 411, driving the motor 407 and the docking seat 406 to move horizontally and dock with the docking block 405 at one end of the winding roller 404. Then, the nonwoven fabric passes around the first guide roller 6, through the two tension rollers 308, and then around the second guide roller 8 before being fixed to the winding roller 404. The motor 407 then drives the winding roller 404 to rotate for winding. The increased diameter of the fabric roll causes the take-up roller 404 to rise, preventing friction between the nonwoven fabric and the take-up table 2. At the same time, the tension motor 306 drives the gear ring 304 to rotate through the gear 305, controlling the swing position of the tension roller 308 and adjusting the wrapping angle and travel path of the nonwoven fabric. This achieves precise and stepless adjustment of the tension of the nonwoven fabric. Once the winding is complete, the hydraulic push rod 412 drives the slider 410 to slide, causing the docking seat 406 to separate from the docking block 405. This facilitates the handling and transfer of the take-up roller 404, reduces human intervention, and improves transfer efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
