[0002] On the circular knitting machine, it is usually used to collect cloth by installing paper tube on the reel; the reel is synchronized with the paper tube in this process, which is very important. Especially for the fabric with spandex, if not synchronized, it is easy to cause wrinkles during the process of cloth rolling, and irreversible creases caused by long-time extrusion and stacking, which cannot be removed in subsequent dyeing and finishing process, resulting in waste products.

[0003] The Chinese patent with application number 2022210431460 and invention name "reel of circular knitting machine" discloses a reel that can adapt to multiple specifications of paper tubes, which opens the clamping jaw by thread and gear cooperation. In the opening and closing process, it needs to rotate more turns to complete, which takes more time. SUMMARY

[0004] In order to overcome the above-mentioned defects, the present application provides an anti-wrinkle reel capable of quickly locking the paper tube.

[0005] In order to achieve the above-mentioned purpose, the anti-wrinkle reel of the present application comprises:

[0006] A hollow shaft tube;

[0007] Two or more pipe supporting devices are arranged at intervals in the hollow shaft tube;

[0008] The pipe supporting device comprises:

[0009] A sleeve,

[0010] A sliding block is arranged to slide in the sleeve;

[0011] A guide bar is arranged on the inner side wall of the sleeve in the axial direction;

[0012] A guide groove is arranged on the sliding block corresponding to the guide bar;

[0013] A spring is arranged between the sliding block and the sleeve;

[0014] Two or more supports are uniformly arranged at the opening end of the sleeve;

[0015] An L-shaped support arm is hinged on the support; the short arm of the L-shaped support arm abuts against the sliding block; the long arm extends forward in the axial direction; the corner of the L-shaped support arm is the hinge point;

[0016] A through hole is provided at the tail of the sleeve, and a transmission rod extends into the sleeve through the through hole; the sliding block is provided with a through hole in the axial direction, and a thread is arranged in the through hole; a groove is arranged on the upper and lower side walls of the through hole, and the length of the groove is equivalent to the length of the sliding block;

[0017] The front end of the transmission rod is provided with a rectangular insertion portion adapted to the groove, and a wide side of the insertion portion is provided with a thread adapted to the slider thread;

[0018] A window is provided on the wall of the hollow shaft tube corresponding to each L-shaped support arm.

[0019] Furthermore, a limiting device is provided at the front end of the insertion portion.

[0020] Furthermore, the pipe support devices are arranged in pairs in a back-to-back manner in the hollow shaft tube; a torsion spring is installed at the hinge of the L-shaped support arm of each pipe support device, and the elasticity of the torsion spring is smaller than the elasticity of the spring in the sleeve;

[0021] A through hole is provided on the sleeve of the left support pipe device at the position corresponding to the slider, the left end of the traction rope passes through the through hole and is fastened to the slider, and the right end passes through the through hole on the sleeve and passes through the support pipe device on the right and is led out from the right end of the hollow shaft tube; a cover plate is provided at the right end of the hollow shaft tube, and an annular support is coaxially provided on the inner side of the cover plate; a circular ring is sleeved in the annular support, and the left and right sides of the circular ring are hinged to the annular support through an axis; the traction rope is fixed behind the circular ring and led out to the right through the cover plate; a push rod 105 is hinged at the lower end of the circular ring, and the other end of the push rod is hinged to the slider; the traction rope is fastened to a pull ring after passing through the cover plate.

[0022] The L-shaped support arms of the present invention are all extended in the same direction to their maximum position. When a paper tube is inserted forward from the rear of the reel, the L-shaped support arms move inward under the influence of the paper tube, thereby forcing the slider to move backward along its axis until the paper tube is fully inserted. Once the paper tube is inserted, rotating the transmission rod 7 through a small angle drives the insertion portion 5 to rotate with it, causing the threads on the insertion portion 5 to engage with the threads in the slider, causing the slider to shift from a sliding state to a slight forward movement driven by the threads. This allows the ends of the L-shaped support arms 6 to abut against the inner arm of the paper tube, thereby quickly securing and supporting the paper tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The application will be further described below with reference to the accompanying drawings.

[0035] Embodiment 1

[0036] As shown in the drawings, the anti-wrinkle reel of the embodiment comprises: Figures 1 to 8

[0037] A hollow shaft tube 1;

[0038] Two supporting tube devices are arranged in the hollow shaft tube in the same direction; and a window 2 is arranged on the wall of the hollow shaft tube corresponding to each L-shaped supporting arm.

[0039] The supporting tube device comprises:

[0040] A sleeve 3, in which a sliding block 4 is arranged to slide;

[0041] A guide strip 31 is arranged on the inner wall of the sleeve in the axial direction; and a guide groove 41 is arranged on the sliding block corresponding to the guide strip; thus the sliding block cannot rotate relative to the sleeve;

[0042] A spring 8 is arranged between the sliding block and the sleeve;

[0043] Two or more than two supports 33 are arranged on the opening end of the sleeve; an L-shaped supporting arm 6 is hinged on the support; the short arm of the L-shaped supporting arm abuts against the sliding block; in order to reduce the friction when the sliding block abuts against the short arm, a roller 44 is arranged on the sliding block corresponding to the position of the short arm; the long arm extends forward in the axial direction; and the corner of the L-shaped supporting arm is the hinge point;

[0044] ​A through hole 32 is formed in the rear end of the sleeve, and a transmission rod 7 extends into the sleeve through the through hole. The transmission rod only rotates relative to the sleeve and does not move forward and backward, and therefore limit pins (not shown in the figure) are arranged on the transmission rod relative to the front and rear positions of the through hole of the sleeve in the axial direction.

[0045] The sliding block is axially provided with a through hole, and a thread 42 is arranged in the through hole. A groove 43 is arranged in the through hole corresponding to the thread 42 in the up and down direction, and the length of the groove is equivalent to the length of the sliding block.

[0046] The front end of the transmission rod is provided with a rectangular insertion part 5 matched with the groove, and the wide side of the insertion part is provided with a thread 51 matched with the thread of the sliding block. In this way, when the insertion part is matched with the groove in the sliding block, the sliding block can move forward and backward in the axial direction, and when the insertion part rotates, the thread of the insertion part is engaged with the thread in the sliding block to limit the movement of the sliding block.

[0047] The front end of the insertion part is provided with a limit nut 71 limiting the maximum movement position of the sliding block.

[0048] The working process is as follows: in the initial state, the thread on the insertion part 5 is not engaged with the thread in the sliding block, and the sliding block is in a sliding state relative to the sleeve; the sliding block moves forward to the position of the limit nut 71 under the action of the spring, and the L-shaped supporting arm 6 is fully opened to the maximum position in the same direction.

[0049] When the paper tube 9 is sleeved from the rear of the reel to the front, the L-shaped supporting arm moves inward under the action of the paper tube, thereby pressing the sliding block to move backward along the axis until the paper tube is completely sleeved.

[0050] When the paper tube is completely sleeved, the transmission rod 7 is rotated by a small angle (the rotation angle is related to the hardness of the inner surface of the paper tube and the concentricity of the paper tube, and the maximum is not more than 180 degrees), which drives the insertion part 5 to rotate, so that the thread on the insertion part 5 is engaged with the thread in the sliding block, and the sliding block changes from the sliding state to a slight forward movement under the driving of the thread, so that the end of the L-shaped supporting arm 6 supports the inner arm of the paper tube, thereby achieving the effect of fixing and supporting the paper tube.

[0051] When the winding operation is completed, the transmission rod 7 is rotated in the opposite direction by a small angle, which drives the thread of the insertion part 5 to disengage with the thread in the sliding block, so that the sliding block is in a sliding state, and at this time the reel (containing the cloth) can be easily pulled out from the rear to the front.

[0052] The transmission rod 7 and the insertion part 5 can be integrally processed or segmented processed according to the actual processing conditions and processing methods, and can be connected into one body by welding or screwing and the like in the later stage.

[0053] Example 2

[0054] like Figures 9 to 11 As shown, the wrinkle-proof reel of this embodiment differs from that of embodiment 1 in that two back-to-back support tube devices are spaced apart within the hollow shaft. This structure cannot be used in the same manner as embodiment 1, and one support tube device must be manually closed before the paper tube can be installed.

[0055] To this end, this embodiment is modified as follows relative to Embodiment 1:

[0056] The threads in the two sliders in the back-to-back pipe support device are rotated in opposite directions; similarly, the threads of the inserting parts on the two transmission rods are adapted to the threads of the corresponding sliders.

[0057] Add a folding device: a) Install a torsion spring (not shown in the figure) at the hinge of the L-shaped support arm of each pipe support device; the elasticity of the torsion spring is less than the elasticity of spring 8.

[0058] b) Add a traction rope 101 for pulling the slider, which is used to pull the two sliders to slide into the sleeve, so that the L-shaped support arm rotates into the hollow shaft tube under the action of the torsion spring.

[0059] As shown in the figure, a through hole is provided on the sleeve of the left support tube device at the position corresponding to the slider (the position of the through hole should be staggered with the position of the L-shaped support arm). The left end of the traction rope 101 passes through the through hole and is fastened to the slider, and the right end passes through the through hole on the sleeve to and through the right support tube device and is led out from the right end of the hollow shaft tube; and for the slider of the right support tube device, a lever device is added between the traction rope and the slider to achieve the effect of pushing the slider into the sleeve. As shown in the figure, a cover plate 102 is provided at the right end of the hollow shaft tube, and the lever device is a circular ring 103, the left and right sides of which are fixed to the annular support 104 of the front cover plate by an axis. The traction rope can be fixed to the upper end of the circular ring 103 by welding or other means; a push rod 105 is hinged to the lower end of the circular ring 103, and the push rod can be directly pressed against the slider or pushed through a slide 106 sleeved on the transmission rod. The traction rope 101 passes through the through hole on the cover plate and is fastened to a pull ring 107. The pull ring has two functions: one is to cooperate with the through hole on the cover plate to limit the sliding distance of the slider out of the sleeve; the other is to pull the traction rope to move the slider into the sleeve.

[0060] The working process is as follows: in the initial state, the thread on the insertion part 5 is not engaged with the thread in the slider, and the slider is in a sliding state relative to the sleeve; the slider moves forward to the position of the limit nut 71 under the action of the spring, and the L-shaped support arms 6 are all stretched in the same direction to the maximum position.

[0061] When the paper tube needs to be installed, the pulling rope is pulled to move the two sliding blocks into the sleeve; the L-shaped supporting arm is rotated and shrunk into the hollow shaft tube under the action of the torsion spring; then the paper tube 9 is sleeved from one end of the reel; after the sleeving is completed, the pulling rope is loosened, the L-shaped supporting arm is quickly opened and supported on the inner side wall of the paper tube under the action of the sliding blocks.

[0062] At this time, the rotating transmission rod 7 is rotated by a small angle (the rotation angle is related to the hardness of the inner surface of the paper tube and the concentricity of the paper tube, and is not more than 180 degrees at most), which drives the insertion part 5 to rotate together, so that the threads on the insertion part 5 are engaged with the threads in the sliding blocks, the sliding blocks are changed from the sliding state to slightly move forward under the driving of the threads, the end of the L-shaped supporting arm 6 is supported in the paper tube, so as to achieve the effect of fixing and supporting the paper tube.

[0063] When the cloth winding action is completed, the rotating transmission rod 7 is rotated in the opposite direction by a small angle, which drives the threads of the insertion part 5 to disengage with the threads in the sliding blocks, so that the sliding blocks are in the sliding state, at this time, the pulling rope is pulled to move the two sliding blocks into the sleeve; the L-shaped supporting arm is rotated and shrunk into the hollow shaft tube under the action of the torsion spring, so that the reel (containing cloth) can be easily pulled out of the hollow shaft tube. The end of the transmission rod can be fixed with a handle to complete the rotation of the transmission rod, of course, a screwdriver or a hexagonal wrench can also be used to complete it.
