Yarn guide for yarn guide of roving frame

Abstract

The utility model discloses a yarn guide for yarn guide of a roving frame, which comprises a support base, a yarn guide cylinder shell is fixedly arranged on the support base, the inner end face of the yarn guide cylinder shell is connected with a yarn guide cylinder in a sliding mode, and the yarn guide cylinder rotates relative to the yarn guide cylinder shell through a rotating motor fixed in the yarn guide cylinder shell. Yarn penetrating through the yarn guide cylinder abuts against balls arranged on the inner end face of the yarn guide cylinder, and burrs on the outer surface of the yarn are smoothed through the balls due to transverse movement of the yarn and longitudinal rotation of the yarn guide cylinder. According to the device, the balls make contact with yarn, friction force between the yarn and the yarn guide barrel is reduced, and the yarn abrasion probability is reduced; when the yarn moves in the yarn guide cylinder, the yarn guide cylinder rotates on the vertical face through the rotating motor, burrs on the surface of the yarn are smoothed through the balls, the contact area between the yarn and equipment in the traction process is further reduced, abrasion is reduced, and therefore the probability of end breakage is reduced.

Description

TECHNICAL FIELD

[0001] The utility model relates to textile equipment technical field, concretely relates to the yarn guide of roving frame yarn guide. BACKGROUND

[0002] In textile machinery, the yarn guide is an indispensable auxiliary device, which is mainly used for guiding the yarn path to make the yarn reach the specified processing mechanism according to the specified path. The roving frame is a textile machine for making fiber sliver into roving, and the main function is traction and twisting. When the yarn guide is used for traction, the surface of the fiber sliver is miscellaneous, and there are burrs. When the yarn is pulled through the yarn guide, friction occurs between the yarn and the yarn guide, which may even cause the yarn to break, resulting in broken ends of the roving, and greatly affecting the working efficiency of the roving frame. SUMMARY

[0003] In view of the above defects or deficiencies in the prior art, it is desirable to provide a yarn guide for a roving frame.

[0004] According to the technical scheme provided by the embodiment of the present application, the yarn guide for the roving frame comprises a supporting base, a yarn guide cylinder housing is fixedly arranged on the supporting base, a yarn guide cylinder is slidably connected to the inner end face of the yarn guide cylinder housing, the yarn guide cylinder rotates relative to the yarn guide cylinder housing through a rotating motor fixed in the yarn guide cylinder housing, the yarn passing through the yarn guide cylinder abuts against the balls arranged on the inner end face of the yarn guide cylinder, and the transverse movement of the yarn and the longitudinal rotation of the yarn guide cylinder make the burrs on the outer surface of the yarn smooth through the balls.

[0005] Further, the yarn guide cylinder is in a conical shape, and the plurality of balls are uniformly distributed at the two end portions of the yarn guide cylinder, so that the yarn is in contact with the balls to reduce friction.

[0006] Further, the yarn guide cylinder is slidably connected to the yarn guide cylinder housing through an annular sliding ring to realize stable rotation of the yarn guide cylinder.

[0007] Further, the outer end face of the yarn guide cylinder is provided with a gear tooth, and a gear fixed on the motor shaft of the rotating motor is engaged with the gear tooth to realize rotation of the yarn guide cylinder.

[0008] Further, the two side end faces of the yarn guide cylinder housing are arc-shaped end faces to reduce the friction force between the yarn and the yarn guide cylinder housing.

[0009] Further, the supporting base is provided with a mounting hole for convenient installation and fixation.

[0010] In summary, the beneficial effects of the present application: the device of the present application utilizes the contact of the ball with the yarn, reduces the friction between the yarn and the guide tube, reduces the probability of yarn wear; while the yarn moves in the guide tube, the guide tube rotates in the vertical plane through the rotating motor, the burrs on the surface of the yarn are smoothed by the ball, further reducing the contact area of the yarn with the equipment during the traction process, reducing wear, thereby reducing the probability of broken ends.

[0016] The present application will be further described in detail below in conjunction with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that, for the sake of description, only the parts related to the application are shown in the drawings.

[0017] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0018] A yarn guide for a yarn guide of a roving frame, as shown in the figure, the upper end surface of the vertically arranged support base 1 is fixedly provided with a guide tube shell 2. Figure 1

[0019] As shown in the figure, the upper end surface of the vertically arranged support base 1 is fixedly provided with a guide tube shell 2. Figure 2 and Figure 3 ​As shown, the yarn guide tube 3 is slidably connected inside the outer shell 2 of the yarn guide tube via an annular slip ring. In order to maintain balance, two annular slip rings with different diameters are located at the left and right ends of the yarn guide tube 3, respectively. The cross-section of the annular slip ring is convex. The annular slip ring is not shown in the attached drawings of the instruction manual. The outer end face of the yarn guide tube 3 is provided with a circular tooth 32. The tooth 32 meshes with the gear on the motor shaft of the rotary motor 4 fixed inside the outer shell 2 of the yarn guide tube. When the rotary motor 4 rotates with the gear, it will drive the yarn guide tube 3 to rotate simultaneously due to the meshing with the tooth 32. The left and right ends of the inner end face of the yarn guide tube 3 are provided with circular rolling balls 31.

[0020] Before use, install the device on the roving frame via the support base 1, and then feed the yarn into the yarn guide tube 3 from the larger diameter end and exit the yarn from the smaller diameter end.

[0021] Due to the yarn, Figure 1 As shown, the yarn enters from the right end and exits from the left end. During the process of the yarn passing through the yarn guide cylinder 3, the rotary motor 4 is started, causing the yarn guide cylinder 3 to rotate. Therefore, the ball bearings 31 inside the yarn guide cylinder 3 will also rotate around the center line of the yarn guide cylinder 3. As a result, the burrs on the outer surface of the yarn come into contact with the ball bearings 31 in a spiral shape, that is, the burrs on the outer surface of the yarn will be smoothed out.

[0022] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
