Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and more specifically, to a silk fabric winding device. Background Technology

[0002] Silk fabric is an expensive fabric woven from silkworm silk. It boasts excellent skin-friendliness and breathability, enhancing comfort when in contact with the skin, especially in clothing. However, as a protein fiber, silk has poor wrinkle resistance and is easily deformed and damaged under strong tension. Therefore, excessive stretching must be avoided during its production and processing. Furthermore, silk fabric requires winding and finishing during production.

[0003] For example, patent application CN218809275 U discloses a fabric winding device, including a U-shaped support frame, a winding roller, and a servo motor for driving its rotation. The roller is supported and driven by a first and second support column in conjunction with a support limiting plate. The second support column contains a hydraulically driven extension column, which can extend and retract to accommodate winding rollers of different sizes. A sliding support plate with an electric lifting rod is provided below the device for easy installation and removal of the roller. This structure enhances the applicability of the equipment, improves winding efficiency, and increases maintenance convenience.

[0004] In the above description, the paper tube is simply fitted around the outer circumference of the take-up roller. When the drive mechanism rotates the take-up roller and begins to wind up the fabric, the paper tube should theoretically rotate synchronously with the take-up roller as a whole. However, due to the lack of a dedicated fixing device between the two, the power transmission relies solely on the limited and unstable static friction between the inner wall of the paper tube and the outer surface of the smooth roller.

[0005] This loose connection method makes the paper tube prone to slippage between the paper tube and the winding roller during the winding process, especially during startup, speed changes, or when subjected to high winding tension. Slippage causes the winding tension applied to the fabric to become unstable and difficult to control precisely. This can further lead to a series of quality problems, such as loose fabric winding, uneven roll ends, wrinkles between layers, and even tensile damage or indentations to delicate silk fabrics due to sudden stress changes.

[0006] Therefore, the unreliable connection between the paper tube and the winding roller, which leads to inaccurate tension control, has become a prominent bottleneck restricting the improvement of winding effect and finished fabric quality. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a silk fabric winding device that can increase the friction between the paper tube and the winding roller.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A silk fabric winding device includes an installation mechanism, a winding mechanism, an adjustment mechanism, and a drive mechanism. The installation mechanism is placed on the ground. The winding mechanism is connected to the mounting mechanism; the adjusting mechanism is mounted on the mounting mechanism and its output end is connected to the winding mechanism; the output end of the drive mechanism is connected to the winding mechanism. The winding mechanism includes a winding roller and multiple contacting components. The winding roller is a hollow tubular component with multiple internally threaded holes evenly distributed along the axial and circumferential directions on its tube wall. The paper tube is fitted onto the outer wall of the winding roller. Each contact component includes a screw, a spring, and a rubber sheet. The screw engages with the internal threaded hole on the wall of the take-up roller and is screwed into the take-up roller. The two ends of the spring are fixedly connected to the rubber sheet and the screw, respectively. The outer peripheral wall of the rubber sheet is provided with an anti-slip structure.

[0009] The present invention is further configured such that the spring is a disc spring.

[0010] The present invention is further configured such that the anti-slip structure is a dense array of anti-slip bumps or anti-slip patterns.

[0011] The present invention is further configured such that: the installation mechanism includes an installation base, an installation plate, and an installation seat; the installation base is a rectangular base, and a through-type placement groove is machined along the length direction at the center of the installation base platform; the adjustment mechanism is placed in the placement groove; the installation plate is a plate-shaped structure, and the lower end of the installation plate is fixedly connected to one side of the upper end face of the installation base; the installation seat is a movable support block, and the lower part of the installation seat is fixedly connected to the adjustment mechanism; the upper part of the installation seat is used to support one end of the winding mechanism.

[0012] The present invention is further configured such that: the adjustment mechanism includes a lead screw, a guide rod, a handle, and a slide; one end of the lead screw is rotatably connected to one end wall of the placement groove; the other end of the lead screw extends to the outside of the mounting base and is fixedly connected to the handle; the guide rod is arranged parallel to the lead screw; both ends of the guide rod are connected to the inner wall of the placement groove through fixed seats; the center of the slide is provided with a threaded hole matching the lead screw; one side of the slide is provided with a smooth through hole; the slide is fitted onto the lead screw through the threaded hole, while the through hole passes through the guide rod; and the mounting base is fixedly installed on the upper end face of the slide.

[0013] The present invention is further configured such that the winding mechanism also includes an insert rod, one end of which is fixedly mounted on the mounting base, and the other end of which is inserted into the hollow tube of the winding roller.

[0014] The present invention is further configured such that: the driving mechanism includes a connecting shaft and a driving component, one end of the connecting shaft is fixedly connected to the driving component, and the other end passes through the mounting hole on the mounting plate and is connected to one end of the take-up roller, the end face of the take-up roller near the driving mechanism is provided with a mating hole, and the end of the connecting shaft is provided with a radial pin hole, and the take-up roller is fixed to the connecting shaft by inserting a pin.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By using multiple contact parts set on the take-up roller, the screw screws engage, the springs provide pre-tension, and the anti-slip structure on the rubber sheet works together to make the rubber sheet tightly press against the inner wall of the paper tube, which significantly increases the friction between the paper tube and the take-up roller. This effectively prevents the paper tube and the take-up roller from sliding relative to each other during the winding process, thereby ensuring the smoothness of the winding process and the winding quality.

[0016] 2. By setting an adjustment mechanism consisting of a lead screw, guide rod, handle and slide, and cooperating with a movable mounting base and insert rod, the position of one end of the take-up roller can be conveniently and precisely adjusted steplessly, enabling the device to quickly adapt to fabrics of different widths and paper tubes of different lengths, thus improving the versatility and ease of operation of the equipment.

[0017] 3. By designing the installation mechanism as a sturdy frame that includes a mounting base with a placement slot, a fixed mounting plate, and a movable mounting seat, and combining it with the pin connection between the connecting shaft and the take-up roller in the drive mechanism, a rigid structure with stable support and reliable transmission is formed. This ensures that the take-up roller rotates smoothly under stress, improving the working stability and service life of the entire device. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 As shown, a silk fabric winding device mainly consists of four parts: an installation mechanism 1, a winding mechanism 2, an adjustment mechanism 3, and a drive mechanism 4. The installation mechanism 1 is placed on the ground to support the winding mechanism 2, the adjustment mechanism 3, and the drive mechanism 4. The winding mechanism 2 is connected to the installation mechanism 1. The adjustment mechanism 3 is placed on the installation mechanism 1 and its output end is connected to the winding mechanism 2. The output end of the drive mechanism 4 is connected to the winding mechanism 2.

[0023] In use, first place the mounting mechanism 1 stably on the work site. Based on the width of the fabric to be wound, move one end of the winding mechanism 2 using the adjusting mechanism 3 to match the effective working length of the paper tube used for mounting the tooling on the winding mechanism 2 with the width of the fabric. Start the drive mechanism 4 to drive the winding mechanism 2 to rotate at a uniform speed, thus smoothly winding the fabric onto the winding mechanism 2.

[0024] like Figure 2 As shown, the mounting mechanism 1 serves as the basic frame of the entire device, and is firmly placed on the ground, providing a mounting base and support for the winding mechanism 2, the adjusting mechanism 3, and the driving mechanism 4.

[0025] The mounting mechanism 1 includes a mounting base 12, a mounting plate 13, and a mounting seat 14.

[0026] The mounting base 12 is a rectangular base that directly contacts the ground to ensure stable operation of the equipment. A through-type placement groove 15 is machined along the length of the center of the mounting base 12's surface. This groove 15 not only accommodates the adjustment mechanism 3 but also guides its sliding motion. To further enhance stability, an anti-slip pad can be added to the bottom of the mounting base 12, or it can be secured with anchor bolts.

[0027] Mounting plate 13 is a plate-like structure, with its lower end fixedly connected to one side of the upper end face of mounting base 12 by welding or high-strength bolts. Mounting plate 13 should be perpendicular to the base plane and have sufficient rigidity to withstand the torque during winding.

[0028] Mounting base 14 is a movable support block located on the other side of mounting base 12. Its lower part is fixedly connected to adjustment mechanism 3, and its upper part is used to support one end of winding mechanism 2.

[0029] like Figure 3 As shown, the two ends of the winding mechanism 2 are connected to the mounting mechanism 1 and the driving mechanism 4, respectively.

[0030] The winding mechanism 2 is the part that directly carries the fabric. It consists of a winding roller 5, an insert rod 20, and an abutment 6. In use, a paper tube is fitted on the outer wall of the winding roller 5 to carry the fabric during winding.

[0031] The take-up roller 5 is a hollow tubular component with a certain wall thickness to ensure torsional rigidity. A mating hole 23 is provided on the end face near the drive mechanism 4. This hole 23 is used to align with the pin hole 24 at the end of the connecting shaft 21. A pin 25, such as a cotter pin or spring pin 9, is inserted to circumferentially fix the take-up roller 5 to the connecting shaft 21, thereby transmitting torque. The take-up roller 5 has a recess for placing the end of the pin 25, preventing uneven fabric winding caused by the pin 25 protruding. Multiple internally threaded holes 7 are evenly distributed along the axial and circumferential directions on the tube wall of the take-up roller 5.

[0032] The insertion rod 20 is a short shaft, one end of which is fixedly mounted on the movable mounting base 14. After the adjustment mechanism 3 is adjusted to the correct position, the insertion rod 20 can be inserted into the hollow tube at the other end of the take-up roller 5, serving as an auxiliary support and centering mechanism.

[0033] like Figure 4 As shown, there are multiple abutment members 6, whose main function is to secure the paper tube to the take-up roller 5, with the paper tube serving as the direct winding core of the fabric. Each abutment member 6 includes a screw 8, a spring 9, and a rubber sheet 10.

[0034] The screw 8 engages with the internal threaded hole 7 on the wall of the take-up roller 5, and can be screwed into the take-up roller 5.

[0035] Spring 9 is a butterfly spring. Spring 9 is fitted onto screw 8, with one end abutting against the head of screw 8 or a washer, and the other end abutting against rubber sheet 10. The butterfly spring 9 has the characteristics of high stiffness, strong shock absorption capacity, and the ability to withstand large loads under small deformations, making it very suitable for occasions where the internal space of the take-up roller 5 is limited.

[0036] The rubber sheet 10 serves as a friction block that directly contacts the inner wall of the paper tube. Under the preload of the disc spring 9, the rubber sheet 10 is pushed outward and pressed tightly against the inner wall of the paper tube. To increase friction and prevent the paper tube from slipping during winding, the outer peripheral wall of the rubber sheet 10 is designed with dense anti-slip bumps or patterns.

[0037] The contact part 6 can be quickly replaced or adjusted by turning the screw 8.

[0038] like Figure 5 As shown, the adjustment mechanism 3 is embedded in the placement groove 15 of the mounting base 12. The adjustment mechanism 3 mainly includes a lead screw 16, a guide rod 17, a handle 18, and a slide 19.

[0039] One end of the lead screw 16 is rotatably connected to one end wall of the placement groove 15, and the other end passes through the through hole at the other end of the placement groove 15, extends to the outside of the mounting base 12, and is fixedly connected to the handle 18. Rotating the handle 18 directly drives the lead screw 16 to rotate.

[0040] The guide rod 17 is an optical axis. Both ends of the guide rod 17 are firmly connected to the inner wall of the placement groove 15 through the fixing seat, and are arranged parallel to the lead screw 16.

[0041] The slide 19 is a slider component with a nut embedded inside. The slide 19 has a threaded hole at its center that matches the lead screw 16, and smooth through holes on both sides. The slide 19 is fitted onto the lead screw 16 through the threaded hole, while the through holes on both sides pass through the guide rod 17. In this way, the slide 19 and the lead screw 16 form a helical transmission pair, and the slide 19 and the guide rod 17 form a sliding guide pair.

[0042] Mounting base 14 is fixedly mounted on the upper surface of slide 19 by bolts.

[0043] During the adjustment process, the operator turns the handle 18, causing the lead screw 16 to rotate. Since the slide 19 is restricted from rotating by the guide rod 17, it moves linearly along the axial direction of the guide rod 17 under the drive of the lead screw 16. The movement of the slide 19 directly drives the mounting base 14 to move synchronously, thereby steplessly adjusting the distance between the mounting base 14 and the fixed mounting plate 13 to accommodate take-up rollers 5 with different winding widths or lengths.

[0044] like Figure 2As shown, the drive mechanism 4 is fixed to one side of the mounting mechanism 1, that is, the side opposite to the connecting surface of the winding mechanism 2. Its power output shaft is connected to the other end of the winding mechanism 2 to provide rotational power for the winding action.

[0045] The drive mechanism 4 includes a connecting shaft 21 and a drive component 22. A bracket is mounted on the outside of the mounting plate 13 to support the drive mechanism 4.

[0046] The drive unit 22 serves as the power source, preferably a speed-regulating motor, but it can also be a drive motor assembly with a reduction gearbox, or other devices that can provide stable rotational output, such as a power head driven by sprockets or pulleys, or even a hand-cranked drive handle in simple applications. The drive unit 22 is securely mounted on the bracket; in this embodiment, a speed-regulating motor is selected.

[0047] The connecting shaft 21 is the power output shaft of the drive component 22. It passes through a pre-drilled mounting hole on the mounting plate 13 and extends into the working area between the mounting plate 13 and the mounting base 14. A radial pin hole 24 is provided at the end of the connecting shaft 21.

[0048] When in use, place the device stably, ensure that the drive unit 22 is powered off, and then put the end of the take-up roller 5 with the docking hole 23 onto the connecting shaft 21 that has extended from the mounting plate 13. Align the docking hole 23 with the pin hole 24 on the connecting shaft 21, insert the pin 25 and lock it. If using a cotter pin, the tail end needs to be pried open.

[0049] Screw the screws 8 of each contact member 6 into the corresponding threaded holes of the take-up roller 5, and initially adjust them to the appropriate positions. Then carefully place the prepared paper tube onto the take-up roller 5. Make the rubber sheet 10 contact the inner wall of the paper tube. Ensure that all contact members 6 are evenly stressed, and that the paper tube is securely fastened without any looseness.

[0050] Based on the actual width of the fabric, turn handle 18 to move mounting base 14 via adjustment mechanism 3 until the insertion rod 20 on mounting base 14 is smoothly inserted into the other end of take-up roller 5. At this point, take-up roller 5 is reliably supported between mounting plate 13 and mounting base 14.

[0051] Secure the fabric end to the paper tube using tape. Start the drive unit 22; it drives the take-up roller 5 and the paper tube to rotate together via the connecting shaft 21, initiating the fabric winding operation. The winding speed and tension can be adjusted via the control system of the drive unit 22.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
