Description

Technical Field

[0001] This utility model relates to the field of fabric winding technology, and in particular to a fabric winding device for all-cotton grey fabric. Background Technology

[0002] A fabric winding device for greige cotton fabric is a specialized piece of equipment used in the textile production process to wind and finish greige cotton fabric. Its core function is to wind the processed greige cotton fabric onto a winding carrier at a certain tension and regularity, forming a fabric roll that is easy to store, transport, and further process. In the production process of greige cotton fabric, the winding device is a key piece of equipment connecting various processing steps, directly affecting the efficiency of subsequent processing and the quality of the finished product.

[0003] However, existing fabric winding devices for all-cotton fabrics have many shortcomings in practical use.

[0004] The installation and disassembly of the take-up carrier are cumbersome. The connection structure between the take-up roller and the limiting component in the existing equipment is complex. Replacing the take-up tube or removing the finished fabric roll requires a lot of time and manpower, reducing production efficiency. At the same time, some equipment has poor mobility and is difficult to adjust its position according to the layout of the production workshop, resulting in poor adaptability. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a fabric winding device for all-cotton fabric, which overcomes the shortcomings of the prior art and effectively solves the problems of cumbersome disassembly and assembly and weak mobility of the winding carrier in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fabric winding device for all-cotton grey fabric includes a movable plate. A winding mechanism and a fastening mechanism are respectively connected to the top two ends of the movable plate. The winding mechanism includes a first support plate, a rotating plate rotatably connected to the top of the inner walls on both sides of the first support plate, a rotating shaft rotatably connected to the outer wall on one side of the rotating plate, a limiting disc welded and fixed to one end of the rotating shaft, a winding roller welded and fixed to the outer wall on one side of the limiting disc, a connecting shaft welded and fixed to one end of the winding roller, a limiting wheel screwed to the outer wall of the connecting shaft, and a winding tube sleeved on the outer wall of the winding roller. The fastening mechanism includes a second support plate, fixed plates symmetrically welded and fixed to the top two sides of the second support plate, a support roller symmetrically rotatably connected between the two fixed plates, T-shaped plates symmetrically rotatably connected to the top two ends of the second support plate, connecting blocks welded and fixed to the bottom two sides of the T-shaped plates, a pressure roller rotatably connected between the two connecting blocks, and pins respectively installed and fixed to the top of the two T-shaped plates.

[0008] Furthermore, casters are fixedly installed at all four corners of the bottom of the movable plate, and the bottoms of the first and second support plates are welded and fixed to the top of the movable plate. The casters have a braking function, which facilitates the operator to move the device within the production workshop. After adjusting to a suitable position, the brakes are locked to ensure stable operation of the device. The welded connection between the first and second support plates and the movable plate ensures the structural stability of the winding mechanism and the fastening mechanism during operation.

[0009] Furthermore, a servo motor is fixedly installed on the outer wall of the other side of the rotating plate, and the output shaft of the servo motor is connected and fixed to the other end of the rotating shaft through a coupling. The servo motor can control the winding speed by adjusting its rotation speed, and its output shaft transmits power to the rotating shaft through the coupling, driving the rotating shaft, limit plate, winding roller and connecting shaft to rotate synchronously, thereby realizing the winding operation of the cotton fabric and ensuring the smoothness and controllability of the winding process.

[0010] Furthermore, the outer wall of the connecting shaft is threaded at one end near the take-up roller, and the thread engages with the limiting wheel. By rotating the limiting wheel, it can be moved along the thread on the connecting shaft, facilitating the fixing or disassembly of the take-up tube sleeved on the take-up roller. The operation is simple and convenient, requiring no complex tools.

[0011] Furthermore, the length of the take-up tube is greater than the length of the take-up roller, and a strip-shaped groove is provided on one side of the outer wall of the take-up tube. The fabric is wound around the take-up tube through the strip-shaped groove, and the take-up tube and the take-up roller are fastened together by a limiting plate and a limiting wheel. The longer length of the take-up tube prevents the fabric from slipping off from both ends during winding; the strip-shaped groove is used to fix the starting end of the fabric to ensure that the fabric does not slip at the beginning of winding; the limiting plate and the limiting wheel limit the take-up tube from both ends to prevent axial displacement of the take-up tube during winding and ensure the regularity of the fabric roll.

[0012] Furthermore, the orientation of the support rollers and pressure rollers is parallel to the orientation of the horizontal connecting shaft, and the bottom of the two support rollers forms a rolling fit with the bottom of the horizontal connecting shaft, while the top of the two pressure rollers forms a rolling fit with the top of the horizontal connecting shaft. The support rollers and pressure rollers clamp and guide the connecting shaft from both the top and bottom to prevent the connecting shaft from shifting during rotation.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The fastening mechanism, through the cooperation of the support roller and pressure roller, clamps and guides the connecting shaft from both the top and bottom, effectively ensuring the stability of the take-up roller in winding the fabric. The winding mechanism's limiting disc and limiting wheel limit the winding tube from both ends, preventing axial displacement and avoiding slippage of the fabric during winding. Simultaneously, the servo motor stably controls the winding speed, ensuring a smooth winding process, solving the problem of poor winding regularity in traditional devices, and improving the appearance quality of the fabric roll and the convenience of subsequent processing.

[0015] 2. The take-up tube achieves quick assembly and disassembly via the threaded engagement of the limiting wheel and the connecting shaft, eliminating the need for complex tools and reducing the time spent changing the take-up tube and removing the fabric roll, thus improving production efficiency. The casters at the bottom of the movable plate allow for flexible movement of the device, enabling adjustments to its position according to the workshop layout, enhancing its adaptability and improving upon the cumbersome assembly and disassembly and inconvenient movement of traditional devices.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] Reference Figure 1-3A fabric winding device for all-cotton grey fabric includes a movable plate 1. A winding mechanism 2 and a fastening mechanism 3 are respectively connected to the top two ends of the movable plate 1. The winding mechanism 2 includes a first support plate 4, a rotating plate 5 rotatably connected to the top of the inner walls on both sides of the first support plate 4, a rotating shaft 6 rotatably connected to the outer wall of one side of the rotating plate 5, a limiting plate 8 welded and fixed to one end of the rotating shaft 6, a winding roller 9 welded and fixed to the outer wall of one side of the limiting plate 8, a connecting shaft 10 welded and fixed to one end of the winding roller 9, and a limiting wheel 1 screwed to the outer wall of the connecting shaft 10. 1. A take-up tube 12 is fitted onto the outer wall of the take-up roller 9. The fastening mechanism 3 includes a second support plate 13, fixed plates 14 symmetrically welded and fixed to the top two sides of the second support plate 13, a support roller 15 symmetrically rotatably connected between the two fixed plates 14, T-shaped plates 16 symmetrically rotatably connected to the top two ends of the second support plate 13, connecting blocks 17 welded and fixed to the bottom two sides of the T-shaped plate 16, a pressure roller 18 rotatably connected between the two connecting blocks 17, and pins 19 respectively installed and fixed to the top of the two T-shaped plates 16.

[0023] Universal wheels are fixed at all four corners of the bottom of the movable plate 1. The bottoms of the first support plate 4 and the second support plate 13 are welded to the top of the movable plate 1. The universal wheels have a braking function, which makes it easy for operators to move the device in the production workshop. After adjusting to a suitable position, the brakes are locked to ensure stable operation of the device. The welded connection between the first support plate 4 and the second support plate 1 and the movable plate 1 ensures the structural stability of the winding mechanism 2 and the fastening mechanism 3 during operation. A servo motor 7 is fixed on the outer wall of the other side of the rotating plate 5. The output shaft of the servo motor 7 is connected to the other end of the rotating shaft 6 through a coupling. The servo motor 7 can control the winding speed by adjusting its speed. Its output shaft transmits power to the rotating shaft 6 through the coupling, driving the rotating shaft 6, the limit plate 8, the winding roller 9 and the connecting shaft 10 to rotate synchronously, thereby realizing the winding operation of the cotton fabric and ensuring the smoothness and controllability of the winding process. The outer wall of the connecting shaft 10 near the winding roller 9 is threaded, and the thread forms a threaded engagement with the limit wheel 11. By rotating the limiting wheel 11, it can be moved along the thread on the connecting shaft 10, which makes it easy to fix or remove the winding tube 12 sleeved on the winding roller 9. The operation is simple and convenient and does not require complicated tools.

[0024] The take-up tube 12 is longer than the take-up roller 9. A strip-shaped groove is provided on one side of the outer wall of the take-up tube 12. The fabric is wound around the take-up tube 12 through the strip-shaped groove. The take-up tube 12 and the take-up roller 9 are securely engaged by a limiting disc 8 and a limiting wheel 11. The longer take-up tube 12 prevents the fabric from slipping off at both ends during winding. The strip-shaped groove is used to fix the starting end of the fabric, ensuring that the fabric does not slip at the beginning of winding. The limiting disc 8 and the limiting wheel 11 limit the take-up tube 12 from both ends to prevent axial displacement during winding, ensuring the regularity of the fabric roll. The support rollers 15 and pressure rollers 18 are parallel to the orientation of the horizontal connecting shaft 10. The two support rollers 15 form a rolling engagement with the bottom of the horizontal connecting shaft 10, and the two pressure rollers 18 form a rolling engagement with the top of the horizontal connecting shaft 10. The support roller 15 and the pressure roller 18 clamp and guide the connecting shaft from the top and bottom sides to prevent the connecting shaft from shifting during rotation.

[0025] The moving and supporting base components: The moving plate 1 is made of high-strength steel plate, and the four corner casters at the bottom are made of wear-resistant rubber and are equipped with a foot-operated braking device. The operator can push the moving plate 1 to move the entire device. When it reaches the designated working position, the operator can step on the braking device to lock the casters and prevent the device from slipping during operation. The first support plate 4 and the second support plate 13 are both welded steel plate structures, fully welded to the top of the moving plate 1 at the bottom. The weld joints are ground to ensure a firm connection, providing stable support for the winding mechanism 2 and the fastening mechanism 3, respectively, and bearing the tension and weight generated during the winding process.

[0026] The winding mechanism consists of two inner walls of the first support plate 4, both sides of which are rotatably connected to the rotating plate 5 via pins. The rotating plate 5 can rotate around the pins at a certain angle, facilitating position adjustment during installation or removal of the winding tube 12. One outer wall of the rotating plate 5 is rotatably connected to the rotating shaft 6 via a bearing. Deep groove ball bearings are used to ensure smooth rotation of the rotating shaft 6 and to withstand radial force. The servo motor 7 is bolted to the other outer wall of the rotating plate 5. The motor output shaft is connected to the other end of the rotating shaft 6 via a flexible coupling. The flexible coupling buffers the impact force during motor start-up and stop, protecting the rotating shaft 6 and the motor. A limiting disc 8 welded to one end of the rotating shaft 6 has a diameter larger than the winding roller 9, serving to block the winding tube 12. The winding roller 9, the limiting disc 8, and the connecting shaft 10 are integrally welded, ensuring structural strength during the winding process. The thread on the end of the connecting shaft 10 near the take-up roller 9 is a fine thread, which mates with the internal thread of the limiting wheel 11. The fine thread has good self-locking properties, which can prevent the limiting wheel 11 from loosening during the winding process. The take-up tube 12 is made of paper or plastic. The width of the strip groove on the outer wall is slightly larger than the thickness of the cotton fabric, which makes it easy to insert the starting end of the fabric into the groove for fixation. After the take-up tube 12 is sleeved on the take-up roller 9, the limiting wheel 11 is rotated to make it fit tightly against the end of the take-up tube 12, which, together with the limiting plate 8, firmly fixes the take-up tube 12.

[0027] Fastening mechanism: The fixing plates 14 welded to the top two sides of the second support plate 13 are rectangular steel plates. The two fixing plates 14 are rotatably connected by bearings to a support roller 15. The support roller 15 has a smooth surface and is made of stainless steel. The T-shaped plate 16 is rotatably connected to the top two ends of the second support plate 13 by a pin. The T-shaped plate 16 can be flipped up and down around the pin. The connecting blocks 17 welded to the bottom two sides are rotatably connected by bearings to a pressure roller 18. When the pressure roller 18 presses on the top of the connecting shaft 10, the positions of the two T-shaped plates 16 are fixed by the pin 19. When it is necessary to replace the winding tube 12, the pin can be pulled out to flip the T-shaped plate 16 and lift the pressure roller 18. The operation is convenient.

[0028] Working principle:

[0029] First, according to the layout requirements of the production workshop, push the movable plate 1 to move the device to the designated working position using the casters at the bottom, and then depress the brake device of the casters to stabilize and fix the device. Next, prepare for winding by pulling out the pin 19 at the top of the T-shaped plate 16 in the fastening mechanism 3, flipping the T-shaped plate 16 upwards, and lifting the pressure roller 18 to make room for the installation of the winding tube 12.

[0030] Then install the take-up tube 12. First, rotate the limiting wheel 11 in the take-up mechanism 2 to move it away from the take-up roller 9 along the thread on the connecting shaft 10, so that the take-up tube 12 is fitted onto the outer wall of the take-up roller 9. Push the take-up tube 12 so that one end is tightly against the limiting disc 8. Then rotate the limiting wheel 11 in the opposite direction so that the limiting wheel 11 is tightly against the other end of the take-up tube 12. The take-up tube 12 is fastened to the take-up roller 9 by the cooperation of the limiting disc 8 and the limiting wheel 11. Next, thread the cotton fabric, inserting the starting end of the fabric into the strip groove on the outer wall of the take-up tube 12. Flip the T-shaped plate 16 downward so that the pressure roller 18 presses on the top of the connecting shaft 10. At this time, the pressure roller 18 and the support roller 15 cooperate to clamp the connecting shaft 10 from the top and bottom. Insert the pin 19 to fix the T-shaped plate 16, completing the threading and fixing of the fabric.

[0031] The servo motor 7 in the winding mechanism 2 is started. The output shaft of the servo motor 7 drives the rotating shaft 6 to rotate via a coupling. The rotating shaft 6 drives the limiting plate 8, the winding roller 9, the connecting shaft 10, and the winding tube 12 to rotate synchronously. The winding tube 12 begins to wind up the fabric. During the winding process, the support roller 15 and the pressure roller 18 guide and clamp the connecting shaft 10, ensuring that the fabric can be wound smoothly on the winding tube 12. The servo motor 7 can adjust its speed according to the thickness and tension requirements of the fabric to ensure a smooth winding process.

[0032] After winding is complete, turn off the servo motor 7, pull out the pin 19 to lift the pressure roller 18, cut the greige fabric, then rotate the limit wheel 11 to remove the winding tube 12 of the wound greige fabric. After replacing the new winding tube 12, the next round of winding operation can be performed. The entire workflow is convenient to operate, with high winding regularity, effectively improving the winding efficiency and quality of cotton greige fabric.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
