Technical Field
[0001] This utility model relates to the field of chemical fiber quilt technology, and in particular to a chemical fiber winding device for the production of chemical fiber quilts. Background Technology
[0002] In the production process of chemical fiber quilts, it is necessary to wind up the chemical fiber materials. The quality of the winding of the chemical fiber materials directly affects the efficiency of subsequent processing and the quality of the products.
[0003] The existing patent publication number is CN215710404U, and the patent title is "A Chemical Fiber Winding Device for Chemical Fiber Quilt Production." This patent includes a base and a winding roller. A mounting frame is provided on the top of the base. Two guide rods are arranged between the left and right sides of the inner wall of the mounting frame. An adjustment component extending to the left side is provided on the right side of the inner wall of the base. Mounting plates extending to the top of the adjustment component and fitting around the two guide rods are provided on both the left and right sides of its top. Rotating components extending to their opposite sides and located between the base and the lower guide rods are provided on the opposite sides of the two mounting plates. A motor frame is located below the left rotating component on the left side of the left mounting plate. This chemical fiber winding device for chemical fiber quilt production can adapt to chemical fiber fabrics of different widths, facilitates the user's disassembly and assembly of the winding roller, improves the work efficiency of workers, and enhances the practicality of the winding device.
[0004] In the above solution, although the take-up roller can be disassembled by adjusting the distance between the two mounting plates, an additional power source is required. Furthermore, there is a lack of dynamic adjustment mechanism for material tension during the winding process. As the winding diameter increases, the winding may become loose or too tight, leading to interlayer misalignment and causing indentations or localized stress concentrations on the material surface. Utility Model Content
[0005] The purpose of this invention is to provide a chemical fiber winding device for the production of chemical fiber blankets, so as to solve the above-mentioned shortcomings in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical fiber winding device for the production of chemical fiber quilts, comprising a frame, with drive shafts installed on both sides of the inner wall of the frame, and a winding roller coaxially installed between the two drive shafts. A coupling sleeve connected to the end of the winding roller is elastically sleeved on the drive shaft. A horizontal plate is fixedly connected inside the frame, and a material abutting mechanism is elastically inserted at the top of the horizontal plate below the winding roller. A material unloading adjustment component is installed inside the frame and is drivenly connected to the material abutting mechanism. When the winding roller winds up the material, the material abutting mechanism presses against the material and gradually descends, thereby driving the coupling sleeve to move away from the end of the winding roller shaft.
[0007] Preferably, a limiting strip is fixedly connected to the inner wall of the coupling sleeve, and slots matching the limiting strip are provided on both the drive shaft and the take-up roller. A top spring is installed between one end of the coupling sleeve and the frame.
[0008] Preferably, the material contacting mechanism includes a lifting frame that is inserted through the horizontal plate, and a pressure spring is sleeved on both sides of the lifting frame. The bottom of the pressure spring is fixed to the top surface of the horizontal plate, and a contact roller is rotatably connected to the top of the lifting frame.
[0009] Preferably, the unloading adjustment assembly includes a push rod slidably mounted on one side of the horizontal plate, an adjusting screw threaded through the bottom of the push rod, one end of the adjusting screw being rotatably connected to the inner wall of the frame, and the other end being fixedly connected to a transmission gear, a transmission rack meshing with the transmission gear being vertically fixedly connected to the lifting frame, and the top of the push rod abutting against one side of the coupling sleeve.
[0010] Preferably, a tilting frame is hinged to the bottom of the horizontal plate, and abutment frames are fixedly connected to both sides of the bottom of the tilting frame, with the abutment frames engaging with the bottom of the lifting frame.
[0011] Preferably, brackets are fixedly connected to both sides of the inner wall of the frame, and the top of the brackets is in contact with the roller shaft of the take-up roller.
[0012] Preferably, the push rod has a horizontal limiting hole for the bracket to pass through.
[0013] Preferably, limit rings are fixedly connected to both ends of the take-up roller.
[0014] This utility model provides a chemical fiber winding device for the production of chemical fiber quilts. It has the following beneficial effects:
[0015] This chemical fiber winding device for chemical fiber production utilizes a flexible coupling sleeve in conjunction with a material unloading adjustment component and a material contact mechanism to achieve rapid unloading after winding. The material contact mechanism continuously presses against the chemical fiber material during the winding process, preventing material loosening. The natural accumulation of material during winding triggers the gradual downward movement of the material contact mechanism, maintaining constant contact pressure while simultaneously adjusting the winding tension. Furthermore, the linkage design between the material contact mechanism and the coupling sleeve ensures that the winding operation and unloading preparation are synchronized. When the winding diameter reaches the preset value, it can quickly contact the transmission connection of the winding roller, facilitating the loading, unloading, and replacement of the winding roller.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-4A chemical fiber winding device for producing chemical fiber quilts includes a frame 1. Drive shafts 2 are installed on both sides of the inner wall of the frame 1. A winding roller 3 is coaxially installed between the two drive shafts 2. A coupling sleeve 4, which is elastically sleeved on the drive shaft 2 and connected to the end of the winding roller 3, is respectively sleeved on the ends of the drive shaft 2 and the winding roller 3 under the action of elastic force. A drive motor is installed on the outside of the frame 1, and the output shaft of the drive motor is connected to one of the drive shafts 2. A horizontal plate 101 is fixedly connected inside the frame 1. A material abutment mechanism 5 is elastically inserted into the top of the horizontal plate 101 below the winding roller 3. A discharge adjustment component 6 is installed inside the frame 1 and is connected to the material abutment mechanism 5. When the winding roller 3 winds up the material, the material abutment mechanism... 5. The material is pressed against and gradually lowered, and then the coupling sleeve 4 is moved away from the end of the take-up roller 3. The chemical fiber material is introduced from the upstream equipment and wound around the surface of the take-up roller 3. At this time, the material contact mechanism 5 is always in close contact with the material surface, providing initial clamping force. The drive motor drives the transmission shaft 2 to rotate, and drives the take-up roller 3 to rotate and take in the material through the coupling sleeve 4. As the take-up diameter increases, the material layer pushes the material contact mechanism 5 down. When the take-up diameter reaches the preset value, the position of the material contact mechanism 5 remains fixed. At this time, the depth of the take-up roller 3 roller shaft inserted into the coupling sleeve 4 decreases as the coupling sleeve 4 moves outward. After pressing down the material contact frame 103, the coupling sleeve 4 can be easily moved away, which is convenient for the staff to adjust or quickly replace the take-up roller 3.
[0024] In a further technical solution of this utility model, a limiting strip 401 is fixedly connected to the inner wall of the coupling sleeve 4. Slots 201 matching the limiting strip 401 are provided on both the drive shaft 2 and the take-up roller 3. A top spring 402 is installed between one end of the coupling sleeve 4 and the frame 1. The preload of the top spring 402 always presses the coupling sleeve 4 against the end of the take-up roller 3, ensuring that the limiting strip 401 and the slots 201 on the drive shaft 2 and the take-up roller 3 are fully engaged. When the take-up roller 3 is in operation, the top spring 402 pushes the coupling sleeve 4 towards the take-up roller 3, thus ensuring the limiting strip 401 is fully engaged with the slots 201 on the inner wall of the coupling sleeve 4. The positioning bar 401 is simultaneously inserted into the slots 201 of the drive shaft 2 and the take-up roller 3. At this time, the positioning bar 401 and the slot 201 form a torque transmission path, ensuring that the power of the drive shaft 2 is stably transmitted to the take-up roller 3. When the material contact mechanism 5 moves down, the unloading adjustment component 6 gradually pulls the coupling sleeve 4 to move outward through the traction rope. During the movement of the coupling sleeve 4, the top spring 402 is compressed and stores energy. The positioning bar 401 slowly exits from the slot 201 of the take-up roller 3, while the slot 201 of the drive shaft 2 remains engaged with the positioning bar 401. As the coupling sleeve 4 moves outward, the subsequent take-up roller 3 can be quickly disassembled and replaced.
[0025] In a further technical solution of this utility model, the material contacting mechanism 5 includes a lifting frame 501 inserted through the horizontal plate 101. Both sides of the lifting frame 501 are fitted with pressure springs 502. The bottom of the pressure springs 502 is fixed to the top surface of the horizontal plate 101. A contact roller 503 is rotatably connected to the top of the lifting frame 501. During the winding process, the contact roller 503, under the elastic force of the pressure springs 502, presses upwards against the chemical fiber material layer on the surface of the winding roller 3. As the winding diameter increases, the contact roller 503 is subjected to material accumulation... The accumulated thrust drives the lifting frame 501 to move down and compress the pressure spring 502. During this process, the elastic force of the pressure spring 502 dynamically balances the material tension to prevent loosening. At the same time, the lifting frame 501 and the unloading adjustment component 6 are linked. When winding continues, the unloading adjustment component 6 allows the coupling sleeve 4 to gradually disengage from the winding roller 3 to complete rapid unloading. After unloading, the pressure spring 502 can push the lifting frame 501 back to the initial height. Before the lifting frame 501 rises, a new winding roller 3 can be installed in advance to prepare for the next round of winding.
[0026] In a further technical solution of this utility model, the unloading adjustment assembly 6 includes a push rod 601 slidably installed on one side of the horizontal plate 101. An adjusting screw 602 is threaded through the bottom of the push rod 601. One end of the adjusting screw 602 is rotatably connected to the inner wall of the frame 1, and the other end is fixedly connected to a transmission gear 603. A transmission rack 504 that meshes with the transmission gear 603 is vertically fixedly connected to the lifting frame 501. The top of the push rod 601 abuts against one side of the coupling sleeve 4. In the initial winding stage, the transmission gear 603 and the transmission rack... When 504 is in a non-transmission state, the coupling sleeve 4 maintains a power connection under the action of the top spring 402. As the winding diameter increases, the lifting frame 501 drives the transmission rack 504 to move downward. The transmission rack 504 drives the transmission gear 603 to rotate, which in turn drives the adjusting screw 602 to rotate, causing the push rod 601 to slowly move to one side and push against the coupling sleeve 4. When the winding diameter reaches the set value, the push rod 601 pulls the coupling sleeve 4 away from the roller shaft of the winding roller 3, completing the power separation, so as to facilitate quick replacement of the winding roller 3 without the need for an additional power source.
[0027] In a further technical solution of this utility model, a flipping frame 102 is hinged to the bottom of the horizontal plate 101. Abutment frames 103 are fixedly connected to both sides of the bottom of the flipping frame 102. The abutment frames 103 abut against the bottom of the lifting frame 501. A torsion spring is installed on the hinge shaft of the flipping frame 102 so that the flipping frame 102 can always be horizontally close to the bottom of the horizontal plate 101. If the diameter of the material wound by the winding roller 3 is insufficient but the winding roller 3 needs to be removed, the flipping frame 102 can be rotated to press down the material abutment mechanism 5 to achieve active unlocking, ensuring that the winding roller 3 can be removed at any time.
[0028] In a further technical solution of this utility model, brackets 104 are fixedly connected to both sides of the inner wall of the frame 1. The top of the bracket 104 contacts the roller shaft of the take-up roller 3. A limiting hole 604 is horizontally opened on the push rod 601 for the bracket 104 to pass through. Both ends of the roller shaft of the take-up roller 3 are always supported by the bracket 104 to ensure smooth rotation of the take-up roller 3. When the push rod 601 moves, its limiting hole 604 and the horizontal plate 101 of the bracket 104 form a sliding pair, limiting the push rod 601 to move precisely in the horizontal direction only, avoiding The push rod 601 is deflected due to the transmission reaction force of the unloading adjustment component 6. When the winding diameter increases and triggers the unloading adjustment component 6, the push rod 601 is driven by the transmission gear 603 to move horizontally outward. The limiting hole 604 slides along the bracket 104 to ensure that the abutment block of the push rod 601 is always aligned with the coupling sleeve 4. The linear movement of the push rod 601 will smoothly pull the coupling sleeve 4 away from the winding roller 3. During this period, the bracket 104 continuously provides radial support for the winding roller 3 to prevent the roller shaft from sagging and deforming due to sudden unloading.
[0029] In a further technical solution of this utility model, both ends of the take-up roller 3 are fixedly connected with limit rings 301. The limit rings 301 can prevent the chemical fiber material from detaching from the take-up roller 3 during the winding process, so that the material contact mechanism 5 can be pressed by the normally wound chemical fiber material, ensuring the corresponding accuracy between the mechanisms.
[0030] When the take-up roller 3 winds up the material, the top spring 402 pushes the coupling sleeve 4 towards the take-up roller 3, causing the limiting strip 401 on the inner wall of the coupling sleeve 4 to simultaneously insert into the slot 201 of the drive shaft 2 and the take-up roller 3. At this time, the limiting strip 401 and the slot 201 form a torque transmission path, ensuring that the power of the drive shaft 2 is stably transmitted to the take-up roller 3. The chemical fiber material is introduced from the upstream equipment and wound around the surface of the take-up roller 3. At this time, the material contact mechanism 5 is always in close contact with the material surface, providing initial clamping force. The drive motor drives the drive shaft 2 to rotate, and drives the take-up roller 3 to rotate and take up the material through the coupling sleeve 4. As the winding diameter increases, the material layer pushes the material abutment mechanism 5 downward. When the winding diameter reaches the preset value, the position of the material abutment mechanism 5 remains fixed. At this time, the depth of the winding roller 3 shaft inserted into the coupling sleeve 4 decreases as the coupling sleeve 4 moves outward. After pressing down the material abutment frame 103, the coupling sleeve 4 can be easily removed, making it convenient for staff to adjust or quickly replace the winding roller 3. If the diameter of the material wound by the winding roller 3 is insufficient but the winding roller 3 needs to be removed, the material abutment mechanism 5 can be pressed down by rotating the flipping frame 102 to achieve active unlocking, ensuring that the winding roller 3 can be removed at any time.
