Description

Technical Field

[0001] This utility model relates to the technical field of textile equipment, and in particular to a guide rail device and a warp threading machine. Background Technology

[0002] During the operation of the warping machine, the guide belt can pull the yarn through the heddle eye and the reed tooth in a preset process sequence.

[0003] Because the yarn is carried by the guide ribbon, it moves back and forth at high speed within the guide groove of the guide rail. Frequent friction between the guide ribbon and the guide rail, and between the yarn and the guide groove wall, easily generates and accumulates a large amount of static charge. Under the influence of electrostatic attraction, the lightweight, soft yarn will float up and adhere to the inner wall of the guide groove or become entangled on the guide ribbon. This phenomenon can cause the yarn to deviate from its normal threading trajectory, resulting in threading failure, machine downtime, severely reduced threading efficiency, and increased monitoring workload for operators.

[0004] To address the aforementioned electrostatic adsorption problem, the industry currently employs two main methods, but both have inherent drawbacks: The first method involves applying antistatic powder. Operators periodically apply powdered substances such as talcum powder or baby powder to the yarn channel or the yarn itself to reduce friction through their lubrication. However, the powder will quickly fall off and disperse during high-speed friction, resulting in a short-lasting effect that requires frequent refilling. The effect is not long-lasting or stable. Furthermore, the dispersed powder can contaminate the precision components inside the equipment and damage it.

[0005] The second type involves active static eliminators. One method is to install grounded conductive fibers near the guide rail to conduct away the static charge generated by friction. However, lint and oil in the textile environment easily adhere to the surface of conductive components, insulating them and hindering static transfer. Another method is to install an ion wind static eliminator, which generates positive and negative ions to neutralize the charge. However, in the harsh conditions of textile workshops with abundant lint and high humidity, the emitter of the ion generator quickly becomes contaminated, causing a sharp drop in neutralization efficiency. The contaminated electrode may even generate a point discharge under high voltage, posing a fire hazard. Utility Model Content

[0028] The following description, in conjunction with the accompanying drawings, describes a guide rail device and a warp threading machine according to an embodiment of the present invention.

[0029] Reference Figure 1 The present invention aims to provide an embodiment of a guide rail device and a warp threading machine.

[0030] A guide rail device according to an embodiment of the present invention includes a track 100, an ejector 120, and a blocking member 130. The track 100 is provided with a guide groove 110 and a sliding member that moves along the guide groove 110. The sliding member can pull a strip-shaped object to a processing position. After the strip-shaped object is processed, the ejector 120 can drive the strip-shaped object to leave the interior of the guide groove 110. After the strip-shaped object leaves the interior of the guide groove 110, the blocking member 130 can prevent the strip-shaped object from entering the interior of the guide groove 110.

[0031] It is understood that this utility model, by setting up the pusher 120 and the blocking member 130, allows the strip to be yarn. During warp threading, the yarn is hooked by the arrow belt and threaded through the guide rail device from the hook position. After the action is completed, the pusher 120 actively drives the strip away from the inside of the guide groove 110 and the sliding member, keeping the strip away from the core area of ​​static electricity accumulation and adsorption. Then, the blocking member 130 blocks the strip after it leaves the guide groove 110 from the track 100, the sliding member and the pusher 120. This method cuts off the contact opportunity between the yarn and the track 100 and the sliding member, and solves the problem of yarn floating and tangling caused by static electricity adsorption. There is no need to eliminate static electricity itself, so it solves the powder and safety problems generated during existing static electricity elimination. It significantly improves the working reliability, efficiency and continuity of the warp threading machine, and reduces downtime and manual supervision burden.

[0032] In some embodiments of this utility model, reference is made to Figure 2 The ejector 120 is provided with an air blowing hole 150, which can blow air into the guide groove 110 to make the strip detach from the inside of the guide groove 110.

[0033] In this embodiment, by setting an air blowing hole 150, compressed air can be blown out. The compressed air can act on the entire yarn instantly, gently and quickly pushing the yarn away from the guide groove 110. The pusher 120 does not need to act directly on the yarn, thus avoiding the problem of the yarn adhering to the pusher 120 due to direct contact between the pusher 120 and the yarn.

[0034] In some embodiments of this utility model, the track 100 includes two guide bars 160, which are arranged opposite to each other and form a guide groove 110 between the two guide bars 160. The push-out member 120 connects the two guide bars 160, so that the air blowing hole 150 is disposed between the two guide bars 160.

[0035] In this embodiment, by setting two guide bars 160 and placing the air blowing hole 150 between the two guide bars 160, and placing the air blowing hole 150 in the middle or near the guide groove 110, the airflow can be applied to the yarn evenly and symmetrically, avoiding the yarn from deflecting or tangling during the push-out due to uneven force, and ensuring the stability and reliability of the push-out action.

[0036] In some embodiments of this utility model, multiple air holes 150 are provided, and the multiple air holes 150 are distributed along the extending direction of the guide groove 110. Therefore, by using multiple air holes to blow air onto the yarn, the yarn can be effectively blown out of the guide groove 110, ensuring the effectiveness of the entire pushing action.

[0037] In some embodiments of this utility model, reference is made to Figure 3The blocking member 130 is provided with a jet hole 140, which can blow air outwards from the track 100 to move the strip away from the track 100.

[0038] In this embodiment, by setting an air jet hole 140, the air jet hole 140 sprays air outward to the outside of the track 100 to form an invisible air wall. The airflow is used to block the yarn and the track 100, so that the yarn is away from the guide rail. There is no need for physical contact with the yarn, which avoids the yarn being attracted by the static electricity of the blocking member 130. Moreover, the airflow can not only block the yarn from returning, but also help the yarn to move further away from the track 100, so the blocking effect is better.

[0039] In some embodiments of the present invention, the guide groove 110 has an opening, the opening is provided on the horizontal side of the guide groove 110, the opening extends along the extension direction of the guide groove 110, the opening allows the strip to move from the inside of the guide groove 110 to the outside, and the jet hole 140 is located on the side of the guide groove 110 near the opening.

[0040] Understandably, the air jet 140 blows air near the opening of the guide groove 110, which can most directly and effectively blow away the yarn that is trying to drift back from the opening, accurately blocking the path of the yarn returning to the guide groove 110, and achieving the best blocking effect with minimal air consumption.

[0041] In some embodiments of this utility model, multiple jet holes 140 are provided, and the multiple jet holes 140 are distributed along the extension direction of the guide groove 110. It can be understood that a continuous and uniform blocking air curtain can be formed along the length direction of the guide groove 110, thereby greatly improving the comprehensiveness and reliability of the blocking effect.

[0042] In some embodiments of this invention, the jet nozzle 140 sprays air vertically or at an angle away from the opening. It is understood that the increased jet direction of the jet nozzle 140 increases the area of ​​the airflow blocking the opening, more actively moving the yarn away from the track 100, preventing the yarn from lingering near the opening, and resulting in a better blocking effect.

[0043] In some embodiments of this utility model, the blocking member 130 is disposed above the guide groove 110, and the bottom of the blocking member 130 is provided with an air jet hole 140. Therefore, blowing air downwards from above can effectively cover the entire opening area of ​​the guide groove 110 and can effectively suppress the tendency of lightweight yarn to float upwards, causing the yarn to move away from the track 100 under the action of gravity and airflow.

[0044] This embodiment also proposes a warp threading machine, which includes the aforementioned guide rail device.

[0045] Therefore, this threading machine can effectively overcome the industry problem of electrostatic adsorption, reduce threading failures and downtime, and thus significantly improve the overall threading efficiency and quality.
