Description

Technical Field

[0001] The present application relates to the technical field of textile machinery and equipment, and in particular to a flat yarn bobbin installation mechanism. Background Art

[0002] Warping machine is a device used in the textile industry to wind a certain number of warp yarns in parallel on the warp beam or weaving beam according to the specified length and width. During the use of the warping machine, it is necessary to ensure that the tension of each warp yarn is equal and evenly distributed on the warp beam or weaving beam to meet the subsequent sizing and drawing-in process requirements.

[0003] The yarn cone is a supporting structure for the yarn, usually consisting of a side disc and a main body of the yarn cone, which are connected by threads to form a cylindrical cavity after installation. The installation of the yarn cone on the warping machine ensures the continuity and uniformity of the yarn, so that the warp yarn can be wound onto the warp beam at a constant tension and speed.

[0004] Reference Figure 1 In the prior art, the installation of the yarn bobbin on the warping machine requires that the yarn bobbin wound with the flat wire be sleeved on the rotating seat 1 on the warping machine. In order to make the rotating seat 1 drive the yarn bobbin to rotate synchronously while rotating, so as to realize the winding and storage of the flat wire, the end positions of the rotating seat 1 close to both ends are both provided with concave annular grooves 2, wherein the concave annular groove 2 on the rotating seat 1 close to the machine side is sleeved with an O-shaped rubber ring 3, and the concave annular groove 2 on the rotating seat 1 away from the machine side is sleeved with a special-shaped rubber ring 4. When the yarn bobbin is coaxially slidably sleeved on the rotating seat 1 along the axial direction of the rotating seat 1, the friction force of the O-shaped rubber ring 3 and the special-shaped rubber ring 4 restrains the yarn bobbin, thereby achieving the purpose of the rotating seat 1 driving the yarn bobbin to rotate synchronously, and also facilitating the replacement of the yarn bobbin wrapped with flat wire.

[0005] The above method of fixing the bobbin on the rotating seat has been found through long-term practical work that the special-shaped rubber ring in the concave ring groove at the end far away from the machine will be severely worn after a few days of work. The friction force of the worn special-shaped rubber ring to fix the bobbin is greatly reduced, which causes the bobbin to move and rotate relative to the rotating seat, affecting the warping machine's precise control of the speed of winding the flat wire of the bobbin and increasing the risk of the flat wire breaking. Therefore, the special-shaped rubber ring needs to be replaced regularly. However, frequent replacement of special-shaped rubber rings not only increases cost consumption, but also reduces the normal working efficiency of the warping machine. Utility Model Content

[0006] In order to improve the working efficiency of a warping machine, the present application provides a flat yarn bobbin installation mechanism.

[0007] The flat yarn drum installation mechanism provided in the present application adopts the following technical solution:

[0008] A flat yarn bobbin mounting mechanism is mounted on a rotating seat on a warping machine, the rotating seat is provided with concave annular grooves at both ends thereof, an O-shaped rubber ring is sleeved in the concave annular groove on the rotating seat close to the machine side, and a clamping piece is sleeved in the concave annular groove on the rotating seat away from the machine side, and the clamping piece limits the movement of the yarn bobbin on the rotating seat through a clamping force.

[0009] By adopting the above technical solution, the yarn tube is fixed tightly by the clamping member, which replaces the traditional friction fixation of the special-shaped rubber ring to the inner wall of the yarn tube, thereby reducing the replacement frequency of the special-shaped rubber ring, reducing cost consumption, improving work efficiency, and avoiding the problem of flat wire breakage caused by wear of the special-shaped rubber ring.

[0010] Optionally, the clamping member is a waist-shaped drum spring that is ring-sheathed in a concave annular groove, and the drum-shaped reed leaf of the waist-shaped drum spring protrudes in a direction away from the axis of the rotating seat. When the yarn tube is slidably sleeved on the rotating seat along the convex guide of the waist-shaped drum spring, the waist-shaped drum spring is arranged to abut against the inner side wall of the yarn tube.

[0011] By adopting the above technical solution and utilizing the elastic deformation characteristics of the drum-shaped reed on the waist-shaped drum spring, elastic tightening of the yarn bobbin is achieved, further improving the installation stability of the yarn bobbin.

[0012] Optionally, an adjustment component for adjusting the axial length of the concave ring groove located on the side away from the machine is provided on the rotating seat, and the adjustment component is used to adjust the clamping force of the side walls at both ends of the concave ring groove along the axial direction on the two ends of the waist-shaped drum spring.

[0013] By adopting the above technical solution, the setting of the adjustment component can achieve fine adjustment of the length of the concave ring groove axis, which can not only tighten the two ends of the waist-shaped drum spring slidably set in the concave ring groove, but also accurately control the tightening force of the waist-shaped drum spring on the yarn tube, which not only ensures the stability of the yarn tube, but also avoids damage to the yarn tube caused by excessive tightening force. This design makes the installation of the yarn tube more flexible and reliable, and adapts to the fixing requirements of yarn tubes of different specifications.

[0014] Optionally, the rotating seat includes a supporting body rotatably connected to the warping machine and an adjusting part coaxially connected to the end of the supporting body, the concave annular groove is jointly located at opposite ends of the supporting body and the adjusting part, the adjusting assembly includes a limiting ring sleeve arranged at the end of the supporting body and a plug-in ring arranged on the adjusting part to match the limiting ring sleeve, a thread is matched between the outer ring side wall of the plug-in ring and the inner ring side wall of the limiting ring sleeve, and the plug-in ring and the limiting ring sleeve are rotationally matched through threads.

[0015] By adopting the above technical solution, the rotating adjustment part, since the threaded rotation adjustment is stepless adjustment, the threaded cooperation between the plug-in ring and the limiting ring sleeve can achieve fine adjustment of the axial length of the concave ring groove, thereby controlling the tightening force of the waist-shaped drum spring.

[0016] Optionally, a plurality of anti-slip ridges are arranged circumferentially on the outer peripheral side wall of the adjusting portion away from the plug-in ring and close to the end portion, and the length direction of each anti-slip ridge is parallel to the axial direction of the adjusting portion.

[0017] By adopting the above technical solution, the provision of the anti-skid ridges enhances the anti-skid performance of the outer surface of the adjustment part, making it easier for operators to perform rotational adjustment operations on the adjustment part.

[0018] Optionally, the clamping member includes a plurality of top support blocks arranged along the circumference of the concave ring groove and an oblique push portion that pushes the top support blocks to extend out of the rotating seat, a dividing block connecting the opposite side walls of the concave ring groove is provided in the concave ring groove corresponding to each two connected top support blocks, and a plurality of sliding grooves connecting the concave ring grooves are provided on the end side walls of the rotating seat, the sliding grooves are located on the side of the concave ring groove facing the axis direction of the rotating seat, and correspond one-to-one with the top support blocks, each of the sliding grooves is parallel to the axis direction of the rotating seat, and the oblique push portion includes an oblique push rod provided corresponding to each sliding groove and a connecting ring that connects the plurality of oblique push rods together, the inclined surface of each oblique push rod facing one side of the top support block, and is inserted into the corresponding sliding groove along the end of the rotating seat, the oblique push rod and the sliding groove are slidably matched, and the connecting ring is abutted against the rotating seat through bolts.

[0019] By adopting the above technical solution, since the top support block has a certain elasticity, it can support the inner wall of the yarn tube. If the top support block is worn after long-term use, the bolt on the connecting ring is rotated to make the inclined push rod slide along the slide groove, thereby pushing the top support block to extend out of the rotating seat, thereby adjusting the clamping force of the top support block on the inner wall of the yarn tube, which can increase the service life of the top support block and improve the durability of the installation mechanism.

[0020] Optionally, limiting grooves are provided on the inner walls on both sides of the concave ring groove along the axis direction of the rotating seat corresponding to each top support block, the length direction of each limiting groove points to the axis center of the rotating seat, and a limiting block is slidably arranged in each limiting groove, each limiting block is connected to the corresponding top support block, and a spring is abutted between each limiting block and the relative side wall of the limiting groove along its own sliding direction.

[0021] By adopting the above technical solution, when the supporting block is pushed outward by the inclined push rod, the spring will be compressed to generate an inward elastic force. When the supporting force of the supporting block needs to be reduced, just loosen the connecting ring, and the elastic force of the spring will push the limit block and the supporting block inward, so that the supporting block is retracted into the concave ring groove.

[0022] Optionally, a chamfer is provided on the side wall of the supporting block which contacts the inclined surface of the inclined push rod.

[0023] By adopting the above technical solution, the contact surface between the inclined push rod and the top support block is smoother due to the chamfered setting, thereby reducing the friction resistance, so that the inclined push rod can push the top support block to move more smoothly.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The yarn tube is fixed tightly by the tightening piece, which replaces the traditional special-shaped rubber ring that fixes the inner wall of the yarn tube by friction, thereby reducing the replacement frequency of the special-shaped rubber ring, reducing cost consumption, improving work efficiency, and avoiding the problem of flat wire breakage caused by wear of the special-shaped rubber ring;

[0026] 2. By utilizing the elastic deformation characteristics of the drum-shaped reed on the waist-shaped drum spring, the elastic tightness of the yarn tube is realized, further improving the installation stability of the yarn tube;

[0027] 3. The setting of the adjustment component realizes the fine adjustment of the length of the concave ring groove axis, which can not only tighten the two ends of the waist-shaped drum spring slidingly set in the concave ring groove, but also accurately control the tightening force of the waist-shaped drum spring on the yarn tube, which not only ensures the stability of the yarn tube, but also avoids damage to the yarn tube caused by excessive tightening force. This design makes the installation of the yarn tube more flexible and reliable, and adapts to the fixing requirements of yarn tubes of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 2-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a flat yarn bobbin installation mechanism.

[0037] Example 1

[0038] Reference Figure 2 A flat yarn bobbin mounting mechanism includes a rotating seat 1 mounted on a warping machine, and the rotating seat 1 is provided with concave annular grooves 2 at both ends thereof. An O-shaped rubber ring 3 is sleeved in the concave annular groove 2 on the rotating seat 1 near the machine side, which is used to abut against the inner wall of the yarn bobbin to increase friction so that the yarn bobbin can rotate synchronously with the rotating seat 1.

[0039] Reference Figure 2 A tightening member 5 is sleeved in the concave annular groove 2 on the rotating seat 1 away from the machine side. The tightening member 5 in this embodiment is a waist-shaped drum spring 51, which is sleeved in the concave annular groove 2. The drum-shaped spring leaf of the waist-shaped drum spring 51 protrudes in the direction away from the axis of the rotating seat 1, forming a convex arc structure. When the yarn tube is slidably sleeved on the rotating seat 1 along the convex guide of the waist-shaped drum spring 51, the drum-shaped spring leaf of the waist-shaped drum spring 51 contacts the inner side wall of the yarn tube, and the elasticity of the waist-shaped drum spring 51 itself generates a tightening force on the yarn tube, thereby fixing the yarn tube.

[0040] Reference Figure 2 and Figure 3 In order to further adjust the pressing force of the waist-shaped drum spring 51 on the yarn tube, an adjustment component 6 is also provided on the rotating seat 1. The rotating seat 1 includes a supporting body 11 and an adjustment part 12, the supporting body 11 is rotatably connected to the warping machine, the adjustment part 12 is coaxially arranged at the end of the supporting body 11, and the concave annular groove 2 is located at the opposite ends of the supporting body 11 and the adjustment part 12, the adjustment component 6 includes a limiting ring sleeve 61 and a plug-in ring 62, the limiting ring sleeve 61 is integrally formed at the end of the supporting body 11, the plug-in ring 62 is integrally formed on the end of the adjustment part 12 with the limiting ring sleeve 61, the outer ring side wall of the plug-in ring 62 and the inner ring side wall of the limiting ring sleeve 61 are matched and provided with threads, and a plurality of anti-skid ridges 121 are arranged on the outer peripheral side wall of the adjustment part 12 away from the plug-in ring 62 near the end, the anti-skid ridges 121 are integrally formed on the adjustment part 12, and the length direction of each anti-skid ridge 121 is parallel to the axial direction of the adjustment part 12.

[0041] Reference Figure 2 and Figure 3 The adjusting portion 12 is rotated by utilizing the anti-slip ridge 121 to make the inserting ring 62 move spirally in the limiting ring sleeve 61 , thereby adjusting the relative position of the supporting body 11 and the adjusting portion 12 .

[0042] The implementation principle of a flat yarn bobbin installation mechanism in the embodiment of the present application is: the rotating adjustment part 12 can achieve fine adjustment of the axial length of the concave ring groove 2 through stepless adjustment of the threaded cooperation between the plug-in ring 62 and the limiting ring sleeve 61, thereby controlling the tightening force of the waist-shaped drum spring 51 on the sleeved yarn bobbin.

[0043] Example 2

[0044] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that a different structure of a clamping member 5 is provided. In this embodiment, the clamping member 5 includes four top support blocks 52 and an inclined push portion 53. The four top support blocks 52 are arranged along the circumference of the concave annular groove 2. A dividing block 7 fixedly connected to the opposite side walls of the concave annular groove 2 is provided between each two connected top support blocks 52 in the concave annular groove 2. The dividing block 7 divides the concave annular groove 2 into four independent small grooves, and the small grooves correspond to the top support blocks 52 one by one.

[0045] Reference Figure 4 and Figure 5 The end side wall of the rotating seat 1 is provided with a slide groove 8 connecting four small grooves. The slide groove 8 is located on the side of the concave ring groove 2 facing the axis direction of the rotating seat 1, and corresponds to the top support block 52 one by one. Each slide groove 8 is parallel to the axis direction of the rotating seat 1. The oblique push portion 53 includes an oblique push rod 531 and a connecting ring 532. One oblique push rod 531 is provided corresponding to each top support block 52. The inclined surface of each oblique push rod 531 faces one side of the top support block 52, and is inserted into the corresponding slide groove 8 along the end of the rotating seat 1. The oblique push rod 531 and the slide groove 8 are slidably matched.

[0046] Reference Figure 4 and Figure 5 The connecting ring 532 is used to fix the four inclined push rods 531 together, and the connecting ring 532 is abutted on the rotating seat 1 by bolts. By rotating the bolts, the inclined push rods 531 can be pushed to move in the slide groove 8. The side wall of the top support block 52 that contacts the inclined surface of the inclined push rods 531 is also chamfered. The chamfer makes the contact surface between the inclined push rods 531 and the top support block 52 smoother, reduces friction resistance, and enables the inclined push rods 531 to more smoothly push the top support block 52 to move in a direction away from the rotating seat 1, thereby pressing against the yarn tube.

[0047] Reference Figure 4 and Figure 5In order to further enhance the sliding stability of the top support block 52, the inner walls on both sides of the concave annular groove 2 along the axis direction of the rotating seat 1 are provided with limiting grooves 13 corresponding to each top support block 52, and the length direction of each limiting groove 13 points to the axis of the rotating seat 1. A limiting block 521 is slidably arranged in each limiting groove 13, and the limiting block 521 and the limiting groove 13 are slidably matched. Moreover, each limiting block 521 is integrally formed on the corresponding top support block 52, and when the top support block 52 moves, it will drive the limiting block 521 to move in the limiting groove 13.

[0048] Reference Figure 4 and Figure 5 At the same time, a spring 9 is abutted between the side wall of each limiting block 521 away from the axis of the rotating seat 1 and the inner side wall of the corresponding limiting groove 13.

[0049] The implementation principle of Example 2 is that by rotating the bolt, multiple inclined push rods 531 can be pushed to move in the slide groove 8, and the inclined surface of the inclined push rod 531 pushes the top support block 52 to extend out of the rotating seat 1, thereby adjusting the pressing force generated by the top support block 52 on the inner wall of the yarn tube. When the top support block 52 is pushed outward by the inclined push rod 531, the spring 9 will be compressed to generate an inward elastic force. When it is necessary to reduce the supporting force of the top support block 52, just loosen the connecting ring 532, and the elastic force of the spring 9 will push the limit block 521 and the top support block 52 to move inward, so that the top support block 52 is retracted toward the concave ring groove 2, thereby realizing an adjustment of the pressing force of the top support block 52 on the yarn tube.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
