Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fabric winding, and in particular to a device and method for directionally winding woven fabrics. Background Art
[0002] When winding fabrics during textile production, the position of the winding drum is generally fixed. As the diameter of the fabric wound on the winding drum increases, the inclination angle between the fabric that has not been wound onto the winding drum and the winding drum becomes larger, and the winding distance between the fabric from the guide rail at the conduction end to the winding drum also continuously changes. Although the rotation speed of the winding drum can be controlled to a certain extent by controlling the driving motor, the inclination angle between the fabric and the winding drum changes, and at the same time, the travel length of the end section of the fabric winding also changes. For example Figure 7 , the traction force on the fabric during initial winding and continuous winding is both F. However, the vertical component force effect generated after continuous winding of the fabric, and the travel length L of the end section of the fabric winding also gradually becomes shorter. Under the same traction force, the shorter the length of the end section of the fabric winding, the greater the degree of deformation (tendency) per unit length of the fabric (common fabrics have a certain elasticity), which affects the overall quality of some fabrics or textile materials with poor tensile resistance. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a device and method for directionally winding woven fabrics, thereby avoiding excessive deformation (tendency) of the fabric and generating "tearing" deformation, ensuring the overall high quality of the fabric, and to a certain extent, ensuring the service life of the lifting structure of the winding drum.
[0004] To solve the above technical problems, the present invention is achieved through the following technical solutions:
[0005] The present invention provides a device for directionally winding woven fabrics. The winding device includes a base frame, a main support and a sub-support fixedly installed on the upper side of the base frame. The upper ends of the main support and the sub-support are fixedly connected to a top frame. A distance sensor for detecting the real-time height of the fabric downward is arranged at the middle position of the top frame. Both the main support and the sub-support are provided with a guiding installation area and side-position guide grooves located on both sides of the guiding installation area. One side wall surface of the side-position guide groove of the main support or the sub-support is embedded with a main side-position pressure sensing belt, and the other side wall surface is embedded with a sub-side-position pressure sensing belt. Axial guide frames are slidably and guidingly installed in the guiding installation areas of the main support and the sub-support. A winding drum is rotatably installed between the axial guide frames of the main support and the sub-support. A driving motor for driving the winding drum to rotate is arranged outside the axial guide frame on the main support side.
[0006] On both sides of the axial guide frame, there are guiding side plates that are fitted and installed at the positions of the side guide grooves. Multiple balls are arranged on the sides of the guiding side plates facing the main side pressure sensing belt and the secondary side pressure sensing belt. Below the axial guide frames of the main support and the secondary support, there are longitudinal guide rods. The bottom end surface of the longitudinal guide rod is embedded with a magnetic disk. An elastic limit frame is fixedly installed in the guiding installation areas of the main support and the secondary support. An axial rod through groove is opened at the middle position of the elastic limit frame. The longitudinal guide rod passes through the axial rod through groove movably, and a longitudinal support spring located above the elastic limit frame is sleeved on the longitudinal guide rod. At the bottom of the guiding installation areas of the main support and the secondary support, there are lifting devices fixedly installed on the upper side of the base frame. The output end of the lifting device is provided with an electromagnetic module facing the magnetic disk.
[0007] As a preferred technical solution of the winding device in the present invention: There is a bottom support below the axial guide frame and the driving motor on the main support side, and there is a bottom support below the axial guide frame on the secondary support side. The longitudinal support spring is located below the bottom support.
[0008] As a preferred technical solution of the winding device in the present invention: A rotating shaft is arranged at the center position of the side end of the winding drum. A bearing sleeve is installed inside the axial guide frame, and the rotating shaft is connected to the bearing sleeve.
[0009] As a preferred technical solution of the winding device in the present invention: The spring constant of the longitudinal support spring on the main support side is greater than that of the longitudinal support spring on the secondary support side.
[0010] As a preferred technical solution of the winding device in the present invention: There are side L plates on both sides of the elastic limit frame. The side L plates are installed at the positions of the side guide grooves. The main support and the secondary support are installed with fixing screws for fixing the side L plates at their respective positions.
[0011] As a preferred technical solution of the winding device in the present invention: The driving motor is horizontally placed, and the output rotating shaft of the driving motor is connected to the rotating shaft of the winding drum facing the main support side.
[0012] The present invention relates to a method for directionally winding woven fabrics, including a static installation test method and a dynamic self-adjustment method.
[0013] (I) Static installation method: ① Install the cloth take-up reel between the main bracket and the auxiliary bracket, and install the axial guide frame, longitudinal guide rod at the positions of the main bracket and the auxiliary bracket, and the drive motor at the position of the main bracket. Install the longitudinal support spring and the elastic limit frame sleeve at the position of the longitudinal guide rod. ② Use a jack to lift the elastic limit frame on the side of the main bracket and the auxiliary bracket upward until the highest point of the cloth take-up reel reaches the horizontal height of cloth winding. ③ The main side pressure sensing belt and the auxiliary side pressure sensing belt sense and monitor the extrusion pressure of the two sides of the guide edge plate on the rolling balls, and linearly adjust the jack on the side of the main bracket or the auxiliary bracket to keep the pressure on the side of the main side pressure sensing belt the same as the pressure on the side of the auxiliary side pressure sensing belt. ④ Use fixing screws to fix the elastic limit frames on the sides of the main bracket and the auxiliary bracket.
[0014] (II) Dynamic self-adjustment method: ① The drive motor starts to drive the cloth take-up reel to wind the cloth. The weight of the continuously winding cloth take-up reel increases linearly, the longitudinal support springs on the sides of the main bracket and the auxiliary bracket are linearly compressed, and the height of the cloth take-up reel and the cloth already wound on the cloth take-up reel decreases linearly. ② The distance sensor senses and monitors the distance downward from the highest point of the cloth already wound on the cloth take-up reel, analyzes the horizontal position of the highest point of the cloth already wound on the cloth take-up reel, and drives and adjusts the real-time highest point position of the cloth already wound on the cloth take-up reel through the lifting device and the electromagnetic module according to the specified height range preset by the system. ③ During the linear descent of the cloth take-up reel and the axial guide frame, the main side pressure sensing belt and the auxiliary side pressure sensing belt sense and monitor the extrusion pressure of the two sides of the guide edge plate on the rolling balls, and adjust the extrusion pressure of the two sides of the guide edge plate on the main side pressure sensing belt and the auxiliary side pressure sensing belt through the interaction between the electromagnetic module and the magnetic disk to keep the pressure on the side of the main side pressure sensing belt the same as the pressure on the side of the auxiliary side pressure sensing belt.
[0015] Among them, in the static installation method: If the pressure on the side of the main side pressure sensing belt is greater than the pressure on the side of the auxiliary side pressure sensing belt, the jack on the side of the main bracket linearly releases the supporting force until the pressure on the side of the main side pressure sensing belt is the same as the pressure on the side of the auxiliary side pressure sensing belt, and then stops linearly releasing the supporting force of the jack. If the pressure on the side of the auxiliary side pressure sensing belt is greater than the pressure on the side of the main side pressure sensing belt, the jack on the side of the auxiliary bracket linearly releases the supporting force until the pressure on the side of the auxiliary side pressure sensing belt is the same as the pressure on the side of the main side pressure sensing belt, and then stops linearly releasing the supporting force of the jack.
[0016] Among them, in the dynamic self-adjustment method: if the highest point position of the fabric already wound on the take-up reel is lower than the specified height range preset by the system, the lifting device drives the output end with the electromagnetic module to linearly rise, pushing the longitudinal guide rod, the axial guide frame, and the take-up reel to rise until the real-time highest point position of the fabric already wound on the take-up reel reaches the lowest point position of the specified height range preset by the system. If the highest point position of the fabric already wound on the take-up reel is higher than the specified height range preset by the system, the electromagnetic module is energized to magnetically attract the magnetic disk on the bottom end face of the longitudinal guide rod, linearly pulling the longitudinal guide rod, the axial guide frame, and the take-up reel to descend until the real-time highest point position of the fabric already wound on the take-up reel reaches the highest point position of the specified height range preset by the system.
[0017] If the pressure on the main side pressure sensing belt side is greater than the pressure on the sub-side pressure sensing belt side, the electromagnetic module on the sub-bracket side enhances the magnetic attraction force on the magnetic disk above it until the pressure on the main side pressure sensing belt side is the same as the pressure on the sub-side pressure sensing belt side, and the electromagnetic module on the sub-bracket side stops enhancing the magnetic attraction force. If the pressure on the sub-side pressure sensing belt side is greater than the pressure on the main side pressure sensing belt side, the electromagnetic module on the main bracket side enhances the magnetic attraction force on the magnetic disk above it until the pressure on the sub-side pressure sensing belt side is the same as the pressure on the main side pressure sensing belt side, and the electromagnetic module on the main bracket side stops enhancing the magnetic attraction force.
[0018] Compared with the existing technology, the beneficial effects of the present invention are as follows:
[0019] 1. In the present invention, axial guide frames are configured on the brackets on both sides of the take-up reel, and longitudinal guide rods, elastic limit frames, and longitudinal position support springs are configured below the axial guide frames. During the process of the fabric winding and gaining weight, the take-up reel and the wound fabric can linearly descend. At the same time, through the driving cooperation between the lifting device and the longitudinal guide rod, and the magnetic attraction cooperation between the electromagnetic module and the magnetic disk, the incoming fabric section to be wound can maintain the initial incoming stroke and incoming angle, avoiding the "tearing" deformation caused by excessive deformation degree (trend) of the fabric in the later stage of winding, and ensuring the overall high quality of the fabric.
[0020] 2. During the pre-installation process of the winding device of the present invention, the installation (pressure) balance between the axial guide frame and the main bracket and the sub-bracket at the initial position is debugged, and during the dynamic winding process, the installation (pressure) balance between the axial guide frame and the main bracket and the sub-bracket is linearly adjusted, reducing the excessive wear of the guiding structure (the ball in the present invention) of the axial guide frame and the main bracket and the sub-bracket during the lifting process of the take-up reel, and ensuring the service life of the lifting structure of the take-up reel to a certain extent.

Detailed implementation manners
[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0031] Embodiment 1
[0032] Please refer to Figure 1 , Figure 2 , the main support 2 and the auxiliary support 3 are vertically and fixedly installed on the upper side of the base frame 1, the top frame 13 is fixedly installed on the upper sides of the main support 2 and the auxiliary support 3, a distance sensor 14 is arranged at the middle position of the top frame 13, and the distance sensor 14 detects the real - time height of the fabric downward.
[0033] The axial guide frame 4 is slidably and guidingly installed in the guide installation area 201 of the main support 2 and the auxiliary support 3 (in combination withFigure 3 ) The take-up reel 8 is rotatably installed between the axial guide frames 4 of the main support 2 and the auxiliary support 3. Rotating shafts 7 are provided at the central positions of both ends of the take-up reel 8. A driving motor 6 is installed outside the axial guide frame 4 on the side of the main support 2. The driving motor 6 drives the take-up reel 8 to rotate. The driving motor 6 is horizontally arranged, and the output rotating shaft of the driving motor 6 is connected to the rotating shaft 7 of the take-up reel 8 facing the main support 2. A bottom support 5 is arranged below the axial guide frame 4 on the side of the main support 2 and the driving motor 6. A bottom support 5 is also arranged below the axial guide frame 4 on the side of the auxiliary support 3. Longitudinal guide rods 9 are fixedly connected below both bottom supports 5. The longitudinal position support springs 11 are sleeved on the longitudinal guide rods 9. The longitudinal position support springs 11 are located above the elastic limit frames 10 and below the bottom supports 5. The longitudinal position support springs 11 support the axial guide frame 4 upward. As more and more fabric is wound on the take-up reel 8, the axial guide frame 4 presses the longitudinal position support springs 11 downward, and the longitudinal position support springs 11 are continuously compressed. The take-up reel 8 and the wound fabric also move downward. The spring constant of the longitudinal position support spring 11 on the side of the main support 2 is greater than that of the longitudinal position support spring 11 on the side of the auxiliary support 3 (because the driving motor 6 is arranged on the side of the main support 2 and the load is larger. If the axial guide frame 4 on the side of the main support 2 wants to lift and lower synchronously with the axial guide frame 4 on the side of the auxiliary support 3, a longitudinal position support spring 11 with a larger spring constant is required).
[0034] Please refer to Figure 3 、 Figure 4 , both the main support 2 and the auxiliary support 3 (in combination with Figure 1 、 Figure 2 ) are provided with vertically oriented guiding and installation areas 201. Side guide grooves 202 are opened on the wall surfaces of the supports on both sides of the guiding and installation areas 201. A main side pressure sensing belt 203 is embedded on one side wall surface of the side guide groove 202 of the main support 2 or the auxiliary support 3, and a secondary side pressure sensing belt 204 is embedded on the other side wall surface.
[0035] Guiding side plates 402 are provided on both sides of the axial guide frame 4. The guiding side plates 402 are fitted and installed in the side guide grooves 202. A plurality of balls 403 are arranged on a set of side surfaces of the guiding side plates 402. The plurality of balls on one side surface face the main side pressure sensing belt 203, and the plurality of balls on the other side surface face the secondary side pressure sensing belt 204. The balls 403 facing the main side pressure sensing belt 203 are in rolling contact with the main side pressure sensing belt 203, and the balls 403 facing the secondary side pressure sensing belt 204 are in rolling contact with the secondary side pressure sensing belt 204. The main support 2 is located on the right side of the auxiliary support 3 (in combination with Figure 1 、 Figure 2 ), and the main side pressure sensing belt 203 is located on the right side of the secondary side pressure sensing belt 204, that is, the "relative position" of the main side pressure sensing belt 203 and the main support 2 is the same. A bearing sleeve 401 is installed inside the axial guide frame 4. The rotating shaft 7 (in combination withFigure 1 , Figure 2 ) is connected to the bearing sleeve 401.
[0036] The elastic limit frame 10 is positioned and installed inside the circumferential direction of the guiding installation area 201 of the main support 2 and the auxiliary support 3 (in combination Figure 1 , Figure 2 ). A shaft rod through groove 1001 is opened at the middle position of the elastic limit frame 10, and the longitudinal guide rod 9 movably passes through the shaft rod through groove 1001. A magnetic disk 901 is embedded at the bottom end surface of the longitudinal guide rod 9.
[0037] The side L plates 1002 are located on both sides of the elastic limit frame 10. The side L plates 1002 are installed at the positions of the side guide grooves 202. The main support 2 and the auxiliary support 3 (in combination Figure 1 , Figure 2 ) are provided with fixing screws 16. The fixing screws 16 are used to fix the side L plates 1002 at their respective positions. Among them, threaded through holes are opened in the main support 2 and the auxiliary support 3, and the fixing screws 16 are screwed and installed at the positions of the threaded through holes. The fixing screws 16 limit and fix the side L plates 1002, thereby completing the position fixing of the elastic limit frame 10. When it is necessary to adjust the position of the elastic limit frame 10, the side L plates 1002 are moved up and down by a certain height, and then fixed with the fixing screws 16.
[0038] The lifting device 12 is fixedly installed on the upper side of the base frame 1 (the lifting device 12 adopts a hydraulic or pneumatic driving device). The lifting device 12 is located at the bottom position of the guiding installation area 201 of the main support 2 and the auxiliary support 3 (in combination Figure 1 , Figure 2 ). An electromagnetic module 1201 is embedded inside the output end of the lifting device 12, and the electromagnetic module 1201 faces the magnetic disk 901.
[0039] Please refer to Figure 5 . When the winding drum 8 just starts to wind the fabric, the diameter and thickness of the fabric to be wound are small, and the distance sensor 14 senses and monitors downward the highest point position of the wound fabric. Refer to Figure 6 . Along with the linear increase in the diameter and thickness of the fabric wound by the winding drum 8, the winding drum 8 and the position of the wound fabric linearly sink. The highest point position of the wound fabric is the same as the highest point position of the wound fabric at the initial winding, and the final stroke and winding angle of the unwound fabric remain unchanged.
[0040] Embodiment 2
[0041] The present invention relates to a method for directionally winding a woven fabric, including a static installation test method and a dynamic self-adjustment method. The specific contents are as follows:
[0042] ㈠ Static installation method
[0043] First, install the winding drum 8 between the main bracket 2 and the auxiliary bracket 3, and install the axial guide frame 4, the longitudinal guide rod 9 at the positions of the main bracket 2 and the auxiliary bracket 3, and the drive motor 6 at the position of the main bracket. Sleeve the longitudinal position support spring 11 and the elastic limit frame 10 on the longitudinal guide rod 9.
[0044] Secondly, use a jack to lift the elastic limit frame 10 on the sides of the main bracket 2 and the auxiliary bracket 3 upward until the highest point of the winding drum 8 reaches the horizontal height of fabric winding.
[0045] Then, the main side pressure sensing belt 203 and the auxiliary side pressure sensing belt 204 sense and monitor the extrusion pressure of the two sides of the guide side plate on the two sides of the ball 403. By linearly adjusting the jack on the side of the main bracket 2 or the auxiliary bracket 3, keep the pressure on the side of the main side pressure sensing belt 203 the same as the pressure on the side of the auxiliary side pressure sensing belt 204.
[0046] Finally, use the fixing screw 16 to fix the elastic limit frame 10 on the sides of the main bracket 2 and the auxiliary bracket 3.
[0047] Among them, in the static installation method:
[0048] If the pressure on the side of the main side pressure sensing belt 203 is greater than the pressure on the side of the auxiliary side pressure sensing belt 204, the jack on the side of the main bracket 2 linearly releases the supporting force until the pressure on the side of the main side pressure sensing belt 203 is the same as the pressure on the side of the auxiliary side pressure sensing belt 204, and then stop linearly releasing the supporting force of the jack.
[0049] If the pressure on the side of the auxiliary side pressure sensing belt 204 is greater than the pressure on the side of the main side pressure sensing belt 203, the jack on the side of the auxiliary bracket 3 linearly releases the supporting force until the pressure on the side of the auxiliary side pressure sensing belt 204 is the same as the pressure on the side of the main side pressure sensing belt 203, and then stop linearly releasing the supporting force of the jack.
[0050] ㈡ Dynamic self-adjustment method
[0051] First, the drive motor 6 starts to drive the winding drum 8 to wind the fabric. The weight of the continuously winding winding drum 8 increases linearly, the longitudinal position support springs 11 on the sides of the main bracket 2 and the auxiliary bracket 3 are linearly compressed, and the height of the winding drum 8 and the fabric wound on the winding drum 8 decreases linearly.
[0052] Secondly, the distance sensor 14 senses and monitors the distance downward to the highest point of the fabric that has been wound by the winding drum 8, analyzes the horizontal position of the highest point of the fabric that has been wound by the winding drum 8 (in the present invention, according to the height of the distance sensor 14 itself and the distance between the highest point position of the fabric and the distance sensor 14, the position of the highest point of the fabric wound by the winding drum 8 can be analyzed), and drives and adjusts the real-time highest point position of the fabric that has been wound by the winding drum 8 through the lifting device 12 and the electromagnetic module 1201 according to the specified height range preset by the system.
[0053] Finally, during the linear descent of the winding drum 8 and the axial guide frame 4, the main side pressure sensing belt 203 and the secondary side pressure sensing belt 204 sense and monitor the extrusion pressure of the rolling balls 403 on both sides of the guiding side plate 402, and adjust the extrusion pressure of the rolling balls 403 on both sides of the guiding side plate 402 on the main side pressure sensing belt 203 and the secondary side pressure sensing belt 204 through the interaction between the electromagnetic module 1201 and the magnetic disk 901, so as to keep the pressure on the main side pressure sensing belt 203 side the same as the pressure on the secondary side pressure sensing belt 204 side [During the frequent lifting and lowering of the lifting structure (such as the axial guide frame 4 that drives the linear lifting and lowering of the winding drum 8 in the present invention), the wear degree of the lifting structure is greatly increased. If the pressure deviates during the directional movement of the lifting structure, for example, the weight distribution of the fabric convolution deviates during the fabric winding process, the wear during the lifting process will be further increased and the service life will be greatly shortened].
[0054] Among them, in the dynamic self-adjustment method:
[0055] If the highest point position of the fabric that has been wound by the winding drum 8 is lower than the specified height range preset by the system, the lifting device 12 drives the output end with the electromagnetic module 1201 to linearly rise, pushing the longitudinal guide rod 9, the axial guide frame 4, and the winding drum 8 to rise until the real-time highest point position of the fabric that has been wound by the winding drum 8 reaches the lowest point position of the specified height range preset by the system.
[0056] If the highest point position of the fabric that has been wound by the winding drum 8 is higher than the specified height range preset by the system, the electromagnetic module 1201 is powered on to magnetically attract the magnetic disk 901 on the bottom end face of the longitudinal guide rod 9, linearly pulling the longitudinal guide rod 9, the axial guide frame 4, and the winding drum 8 to descend until the real-time highest point position of the fabric that has been wound by the winding drum 8 reaches the highest point position of the specified height range preset by the system.
[0057] If the pressure on the main side pressure sensing belt 203 side is greater than the pressure on the secondary side pressure sensing belt 204 side, the electromagnetic module 1201 on the secondary bracket 3 side enhances the magnetic attraction force on the magnetic disk 901 above it until the pressure on the main side pressure sensing belt 203 side is the same as the pressure on the secondary side pressure sensing belt 204 side, and then the electromagnetic module 1201 on the secondary bracket 3 side stops enhancing the magnetic attraction force. If during the subsequent process, the pressure on the main side pressure sensing belt 203 side is less than the pressure on the secondary side pressure sensing belt 204 side, the magnetic attraction force of the electromagnetic module 1201 on the secondary bracket 3 side is linearly released.
[0058] If the pressure on the secondary side pressure sensing belt 204 side is greater than the pressure on the main side pressure sensing belt 203 side, the electromagnetic module 1201 on the main bracket 2 side enhances the magnetic attraction force on the magnetic disk 901 above it until the pressure on the secondary side pressure sensing belt 204 side is the same as the pressure on the main side pressure sensing belt 203 side, and then the electromagnetic module 1201 on the main bracket 2 side stops enhancing the magnetic attraction force. If during the subsequent process, the pressure on the secondary side pressure sensing belt 204 side is less than the pressure on the main side pressure sensing belt 203 side, the magnetic attraction force of the electromagnetic module 1201 on the main bracket 2 side is linearly released.
[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
