AI Technical Summary
When traditional warp spinning machines encounter defects or broken warp yarns on the take-up rollers, they need to stop for repairs, which leads to loosening and tangling of the warp yarns. Furthermore, the existing tensioning mechanism has a limited tensioning stroke, making it difficult to effectively solve the loosening problem.
Design a warp reversing winding structure, including a take-up roller, a guide roller, a moving roller, a reversing roller, and a tensioning roller. The reversing roller is driven by a motor to rotate forward and backward, causing the warp to wind. Combined with multiple direction changes and position adjustments of the tensioning roller, the warp is ensured to remain taut when it breaks up.
During the unwinding process, the reversing rollers drive the warp threads to wind, preventing loosening and tangling. The warp threads are dispersed before winding to ensure winding quality, reduce equipment interference, and improve tension.

Description
Technical Field
[0001] This utility model relates to the field of warp spinning machine equipment technology, and in particular to a warp yarn reversing and straightening structure. Background Technology
[0002] In the textile industry, the warp spinning machine is a key piece of equipment used to process warp yarns. Its main function is to draw the warp yarns from the yarn bobbin and, after a series of processing steps, form warp sheets that meet manufacturing requirements. The quality of the warp yarns directly affects the quality of the fabric; therefore, it is essential to ensure the quality of the warp yarns during the processing.
[0003] In traditional warp spinning machines, if defects or breaks are found in the warp yarn wound on the take-up roller, the machine usually needs to be stopped for dewinding. This process not only loosens subsequent warp yarns but also loosens already wound, potentially leading to tangled yarns. When tensioning is attempted again after this process, it affects the overall tension of the warp yarns, thus reducing the winding quality. Typically, a tensioning mechanism is added to tighten the warp yarns; however, the tensioning stroke of a typical tensioning mechanism is limited, making it difficult to provide sufficient tension for dewinding warp yarns.
[0004] Therefore, this utility model provides a warp reversing winding structure that keeps the warp thread in a taut state when reversing and breaking the roll. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Figures 1-8 It is obvious that the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.
[0028] In order to prevent the warp loosening and disorder when winding the broken warp, the warp reversing and straightening structure of the embodiment comprises a frame 1 which is combined by welding a plurality of metal pipes.
[0029] The thread collecting roller 16 is rotatably installed on the rear part of the frame 1, and the shaft head of the thread collecting roller 16 is connected with a motor one which is fixedly installed on the frame 1 through chain transmission, and the motor one can drive the thread collecting roller 16 to reverse.
[0030] The guide roller 2 is rotatably installed on the lower side of the front of the frame 1, that is, the obliquely lower side of the front, and the guide roller 2 has a certain distance with the thread collecting roller 16, and the distance is between 0.5-2 meters.
[0031] The reversing roller 3 is rotatably installed on the side of the frame 1 which faces the thread collecting roller 16, and the reversing roller 3 is also connected with a motor two which is arranged on the frame 1 through chain transmission, and the motor two can drive the reversing roller 3 to reverse and self-lock.
[0032] The movable tension roller 6 is arranged above the reversing roller 3 on the frame 1, and the position of the tension roller 6 is adjusted to adjust the tension of the thread.
[0033] The movable moving roller 7 is arranged above the guide roller 2 on the frame 1, and the fixed roller 15 is fixed on the frame 1 within the stroke range of the moving roller 7 facing the guide roller 2.
[0034] The tension roller 6 is provided with a plurality of ring grooves 17 arranged axially and the reversing roller 3 is provided with a through groove 18 corresponding to the ring groove 17.
[0035] According to the above technical scheme:
[0036] In use, referring to the accompanying drawings, the thread is guided from the outside, passes below the guide roller 2 and winds around the guide roller 2 to change direction counterclockwise. Figure 4 The thread after the first change of direction winds around the moving roller 7 clockwise to change direction again.The thread after the second change of direction is guided below the reversing roller 3, passes into the through groove 18 from below the through groove 18, and then passes out of the through groove 18 from the upper end of the through groove 18. The thread passing out of the through groove 18 winds around the tension roller 6 clockwise and is in the ring groove 17 on the tension roller 6. The thread winding around the tension roller 6 winds around the take-up roller 16 counterclockwise, and the take-up roller 16 rotates counterclockwise to wind the thread. Figure 4
[0037] The thread is guided through multiple changes of direction, so that the thread is dispersed before winding, and the thread is separated from the root by passing through the through groove 18 and the ring groove 17 in sequence, so that the problems of winding and disorder are avoided.
[0038] When a defect or a broken thread is detected on the take-up roller 16, the motor stops and the take-up roller stops winding the thread.
[0039] At the same time of breaking the winding, the motor two drives the reversing roller 3 to rotate, and since the thread passes through the through groove 18, the rotation of the reversing roller 3 will cause the thread to wind around the reversing roller 3, so that the thread loosened by breaking the winding is wound up, avoiding the thread from being loose and hanging on the equipment components.
[0040] After stopping the breaking of the winding, the motor two is turned off and the reversing roller 3 stops winding.
[0041] After the processing is completed, the moving roller 7 and the tensioning roller 6 are reset; the motor one and the motor two are started, the motor one drives the take-up roller 16 to rotate to continue winding the warp, the motor two drives the reversing roller 3 to rotate to unwind the warp, the unwound warp is gradually wound on the take-up roller 16, and after the warp wound on the reversing roller 3 is unwound, the motor two is stopped and braked, and the motor one continues to drive the take-up roller 16 to rotate to wind the warp.
[0042] In the embodiment, the guide roller 2 is sleeved with a swing lever one 4 rotatably installed on the rack 1 at both ends of the shaft head, and the swing lever one 4 is fastened with the guide roller 2 into an integral body through a screw; and the guide roller 2 extends a extending rod at one end of the rack 1, a pneumatic rod one 9 is rotatably installed on the rack 1, the extending end of the pneumatic rod one 9 is rotatably connected with the non-rotating axis part of the extending rod, and the swing lever reciprocating swing can be driven through the extension and contraction of the pneumatic rod one 9. The moving roller 7 is rotatably installed on the upper end of the two swing lever ones 4, and then the extension and contraction of the pneumatic rod one 9 controls the moving roller 7 to reciprocating swing around the axis of the guide roller 2, so as to realize the position shift and brake of the moving roller 7.
[0043] In the embodiment, the reversing roller 3 is sleeved with a swing lever two 5 rotatably installed on the rack 1 at both ends of the shaft head, and a pneumatic rod two 10 is rotatably installed on the rack 1, the extending end of the pneumatic rod two 10 is rotatably connected with the non-rotating axis part of the swing lever two 5. The swing lever two 5 is provided with an open sliding groove at the upper end, a sliding block is slidably installed in the sliding groove, a tensioning spring 8 is arranged between the sliding block and the sliding groove, and the tensioning roller 6 is rotatably installed at both ends of the two sliding blocks. The extension and contraction of the pneumatic rod two 10 can control the tensioning roller 6 to reciprocating swing and shift around the reversing roller 3 and brake; and the setting of the tensioning spring 8 realizes the tensioning adjustment of the warp by the tensioning roller 6.
[0044] In the embodiment, referring to the accompanying drawings Figures 4-6 As shown in the drawings, the upper end surface of the tensioning roller 6 is not lower than the lower end surface of the take-up roller 16, so that the warp around the tensioning roller 6 has sufficient tensioning adjustment effect.
[0045] In the embodiment, the fixed roller 15 is arranged above the warp and separated from the warp to ensure the clamping of the warp by the moving roller 7 and the fixed roller 15.
[0046] In the further embodiment of the scheme, a structure capable of adjusting the tensioning force of the tensioning roller 6 is provided.

When the tensioning distance of the tensioning roller 6 is insufficient to straighten the warp, the supporting plate 11 can be moved upward by screwing the stud 12 to increase the extrusion of the tensioning spring 8, so as to improve the tightening effect of the warp by the tensioning roller 6.
[0047] In the further embodiment of the embodiment 3, the air pressure rod one 9 and the air pressure rod two group device control the moving roller 7 and the tension roller 6 respectively, which increases the production cost of the device. Therefore, in the embodiment, referring to the drawings Figure 7 The air pressure rod one 9 and the air pressure rod two 10 are omitted, and the air pressure rod three 13 is arranged between the guide roller 2 and the reverse roller 3 on the rack 1.
