Description

Technical Field

[0001] The utility model relates to the technical field of textile guide rollers, in particular to a reciprocating and rotating guided composite yarn guide roller. Background Art

[0002] In the spinning texturing machine, when winding the silk thread, in order to evenly wind the silk thread on the paper tube, it is necessary to pull the silk thread back and forth to make the silk thread move back and forth, so as to evenly wind it on the paper tube into a coil. This winding method requires a wire guide to cooperate with the reciprocating translation of the wound silk thread. The current method is to clamp the silk thread on two rollers for clamping and pulling, and then guide and pull the silk thread through the reciprocating motion of the wire guide.

[0003] This method of clamping the wire with two rollers increases the friction between the wire and the rollers, clamping the wire and causing the wire to be blocked. This makes the wire guide at the rear prone to jumping when it moves forward, and the wire may curl up or be unevenly wound when it is wound. In this case, the production process will cause serious wire jumping, and the wire end face will form a threaded shape and a large wave shape. In severe cases, it may be accompanied by abnormal conditions such as mesh wire, resulting in degradation of the grade of the wire roll.

[0004] Based on this, the utility model designs a reciprocating and rotating guided composite yarn guide roller to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a composite yarn guide roller with reciprocating rotation guidance, and adds an inwardly recessed guide groove on the flat guide roller, so that the silk thread is no longer clamped between the driving roller and the guide roller, but is limited in position in the guide groove, and the silk thread can move back and forth in the guide groove. Although the silk thread is guided and constrained by the guide, it is not clamped, thereby reducing the friction area between the surface of the silk thread and the guide roller and the driving roller, further reducing the friction force, thereby reducing the jumping of the silk thread during winding, and effectively avoiding and alleviating various abnormal situations caused by excessive friction during silk thread winding.

[0006] The utility model is implemented as follows: a reciprocating and rotating guided composite yarn guide roller, comprising:

[0007] Guide rollers, wire guide grooves and drive rollers;

[0008] The guide roller is a roller, and the guide roller is rotatably mounted on a machine platform, and the rotation axis of the guide roller is horizontally arranged;

[0009] The wire guide groove is a wave-shaped groove connected end to end, the wire guide groove is recessed inwardly and opened on the cylindrical side wall of the guide roller, and the crests and troughs of the wire guide groove are distributed in the left-right direction and cover the left and right sides of the guide roller;

[0010] The guide roller is externally covered with an anti-skid rubber layer;

[0011] The driving roller is a round roller, and the rotating shaft of the driving roller is connected to the driving shaft of the motor;

[0012] The side wall of the driving roller is tightly fitted with the side wall of the guide roller, and the axes of the guide roller and the driving roller are parallel to each other in the same vertical plane.

[0013] Furthermore, the cross section of the wire guide groove is a U-shaped groove, and the depth d of the wire guide groove on the guide roller is between 3-7 mm.

[0014] Furthermore, the guide roller and the driving roller have the same diameter.

[0015] The beneficial effects of the utility model are as follows: 1. The inwardly concave wire guide groove is added to the flat guide roller, which can effectively limit the range of movement of the wire and make the wire no longer clamped between the driving roller and the wire guide roller, but the position of the wire is limited in the wire guide groove. The wire can move back and forth in the wire guide groove. Although the wire is guided and constrained by the wire guide, it is not clamped, which effectively avoids the situation where the wire is clamped to produce excessive resistance, and also reduces the friction force in the process of the wire moving, thereby reducing the jumping of the wire during winding, and effectively avoiding and alleviating various abnormal situations caused by excessive friction during the winding of the wire;

[0016] 2. The wire guide groove is a U-shaped groove, which can restrain the wire more smoothly without getting hung up, is convenient for movement, and has stable guidance. Moreover, the wire guide groove is wavy and continuous from beginning to end, so the wire is guided smoothly and seamlessly, without any pause or jump during wire guidance, ensuring accurate wire guidance.

[0024] See also Figures 1 to 4 As shown, the utility model provides a reciprocating and rotating guided composite yarn guide roller. In a specific embodiment of the technical solution of the utility model:

[0025] It includes a guide roller 1, a wire guide groove 11 and a driving roller 2;

[0026] The guide roller 1 is a roller, and the guide roller 1 is rotatably mounted on a machine platform, and the rotation axis of the guide roller 1 is horizontally arranged;

[0027] The wire guide groove 11 is a wavy groove connected end to end. The wire guide groove 11 is recessed inwardly and opened on the cylindrical side wall of the guide roller 1. The crests and troughs of the wire guide groove 11 are distributed in the left-right direction and cover the left and right sides of the guide roller 1. The cross-section of the wire guide groove 11 is a U-shaped groove, and the depth d of the wire guide groove 11 recessed on the guide roller 1 is between 3-7 mm.

[0028] The guide roller 1 is covered with an anti-skid rubber layer, which facilitates the synchronous rotation of the guide roller 1 and the driving roller 2 without slipping, and can make the guide roller 1 and the driving roller 2 fit tightly, ensuring that the wire will not escape from the wire guide groove 11 and move left and right.

[0029] The driving roller 2 is a round roller, and the rotating shaft of the driving roller 2 is connected to the driving shaft of the motor;

[0030] The side wall of the driving roller 2 is closely fitted with the side wall of the guide roller 1, and the axes of the guide roller 1 and the driving roller 2 are parallel to each other in the same vertical plane.

[0031] The guide roller 1 and the driving roller 2 have the same diameter. Such the same diameter can ensure that the guide roller 1 and the driving roller 2 rotate synchronously.

[0032] The technical problem solved by the utility model is: through the recessed design of the wire guide groove 11, the traveling wire is constrained inside the wire guide groove 11 to avoid the wire slipping and skewing, and there is no need to use two rollers to clamp the wire through a large friction force, which effectively avoids the pulling resistance of the friction force on the travel of the wire, thereby avoiding the jumping of the wire caused by clamping.

[0033] The technical effects achieved are as follows: 1. Adding an inwardly recessed wire guide groove 11 on the flat guide roller 1 can effectively limit the range of movement of the wire, and at the same time, the wire is no longer clamped between the driving roller 2 and the guide roller 1, but is limited in position in the wire guide groove 11. The wire can move back and forth in the wire guide groove 11. Although the wire is guided and constrained by the wire guide, it is not clamped, which effectively avoids the situation where the wire is clamped to produce excessive resistance, and also reduces the friction force during the movement of the wire, thereby reducing the jumping of the wire during winding, and effectively avoiding and alleviating various abnormal situations caused by excessive friction during winding of the wire;

[0034] 2. The wire guide groove 11 is a U-shaped groove, which can restrain the wire more smoothly without hanging the wire, is convenient to move, and has stable guidance. Moreover, the wire guide groove 11 is wavy and continuous from beginning to end, so the wire guide is smooth and seamless, so that there is no pause or jump during the wire guidance, ensuring accurate wire guidance.

[0035] The technical solution in the embodiment of the utility model is to solve the above problems, and the overall idea is as follows:

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] When the utility model is in use, the wire is placed in the wire guide groove 11, and the driving roller 22 rotates, which drives the guide roller 1 to rotate. The wave-shaped undulation of the wire guide groove 11 moves left and right with the rotation of the guide roller 1. The wire is wound on the driving roller 2, but the wire is not wound on the guide roller 1, but only passes through the idle space of the wire guide groove 11, that is, the wire comes from above and is wound on the driving roller 2. The wire moves back and forth horizontally in the left and right directions through the wire guide, so that the wire is pulled back and forth, and the wire It moves back and forth left and right between the guide roller 1 and the driving roller 2, and the best state of the silk thread is to move back and forth in the wire guide groove 11, and the silk thread does not contact the guide roller 1, and the silk thread is only constrained and pulled in the wire guide groove 11 to ensure that the silk thread will not deviate, the silk thread will not fly due to loss of tension, and the silk thread will not scatter randomly, ensuring that the silk thread always moves back and forth in the wire guide groove 11, and the guide roller 1 and the driving roller 2 no longer clamp the silk thread up and down, but guide and limit the silk thread through the channel of the wire guide groove 11.
