Description

Technical Field

[0001] The utility model relates to the technical field of double-rapier looms, in particular to a weft joining and edge locking device of a double-rapier loom. Background Art

[0002] A rapier loom is a device used in the textile industry to produce various types of fabrics. This loom uses two swords when working, which move during the weaving process. One of the swords is used to separate the warp threads for the weft threads to shuttle, and the other is used to push in and press the woven fabric.

[0003] During the processing, the weft-joining and edge-locking device is used to deal with the edge problem of the fabric. It is usually used to ensure that the edge of the cloth remains neat during the weaving process and enhance the edge tensile performance. However, the existing weft-joining and edge-locking device squeezes the edge of the cloth through the limit rod, resulting in high friction on the edge of the cloth, which can easily cause burrs and pilling on the edge of the cloth. For this reason, we propose a weft-joining and edge-locking device for a double rapier loom to solve the existing problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a weft joining and edge locking device for a double rapier loom.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a weft-joining and locking device for a double-rapier loom, comprising a base, a motor, a mounting frame, a travel seat and a collecting box, wherein symmetrically distributed travel seats are arranged above the base, and mounting frames are arranged at opposite ends of the travel seats, and guide wheels equidistantly distributed are rotatably installed on the inner walls of the mounting frames, and collecting boxes are arranged at opposite ends of the travel seats, and a fan is embedded in the collecting box, and a suction pipe is installed between the collecting box and the mounting frame, a nut is arranged at the lower end of the travel seat, a motor is arranged inside one end of the base 7, and a screw rotatably inserted in the nut is arranged at the output end of the motor, and symmetrically distributed hooks and weft guides are respectively arranged on one side of the travel seat.

[0006] Preferably, the outer wall of the guide wheel is provided with symmetrically distributed limiting rings. The fiber rings limit the upper and lower positions of the passing cloth to prevent the cloth from falling off the guide wheel.

[0007] Preferably, a filter is provided inside the collection box, and the suction end of the fan is located on one side of the filter. The filter intercepts the sucked fluff to prevent it from entering the fan.

[0008] Preferably, a slider is provided at the lower end of the nut, a symmetrically distributed guide rail is provided at the upper end of the base, and the lower end of the slider is slidably mounted inside the guide rail. The travel seat slides on the guide rail through the slider to obtain a sliding guide.

[0009] Preferably, one end of the hook needle is provided with a support plate 1 fixedly connected to the travel seat, and one end of the weft guide is provided with a support plate 2 fixedly connected to the travel seat. The support plate 1 supports the hook needle, and the support plate 2 supports the weft guide, so that it moves with the travel seat.

[0010] Preferably, a conductor roller is disposed on one side of the travel seat and is located above the first support plate and the second support plate, and support rods connected to the base are disposed at both ends of the conductor roller. The conductor roller supports the bottom of the textile line passing through.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model fixes the edge of the cloth with the guide wheel, and the edge of the cloth avoids direct friction with the structural parts when it moves. The guide wheel limits and adjusts the edge of the cloth while rotating and contacting the edge of the cloth, and the spacing of the guide wheels is adjustable. Because the guide wheel is installed on the travel seat, the screw pushes the thread to drive the installation frame to move relative to or away from each other, and then the relative position of the guide wheel is adjusted to adapt to different specifications of cloth woven by the double rapier loom, and the flexibility is improved during use.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4 As shown, the utility model proposes a weft joining and locking device for a double rapier loom, comprising a base 7, a motor 9, a mounting frame 14, a travel seat 15 and a collecting box 16. A symmetrically distributed travel seat 15 is arranged above the base 7, a mounting frame 14 is arranged at one opposite end of the travel seat 15, and guide wheels 13 equidistantly distributed are rotatably installed on the inner wall of the mounting frame 14. A nut 4 is arranged at the lower end of the travel seat 15, a motor 9 is arranged inside one end of the base 7, and a screw 5 rotatably inserted in the nut 4 is arranged at the output end of the motor 9. A symmetrically distributed hook is arranged on one side of the travel seat 15. The hook needle 1 and the weft guide 11, the outer wall of the guide wheel 13 is provided with symmetrically distributed limit rings 19, the lower end of the nut 4 is provided with a slider 8, the upper end of the base 7 is provided with a symmetrically distributed guide rail 6, the lower end of the slider 8 is slidably installed inside the guide rail 6, one end of the hook needle 1 is provided with a support plate 2 fixedly connected to the travel seat 15, one end of the weft guide 11 is provided with a support plate 2 10 fixedly connected to the travel seat 15, and one side of the travel seat 15 is provided with a wire roller 12 located above the support plate 1 2 and the support plate 2 10, and both ends of the wire roller 12 are provided with support rods 3 connected to the base 7.

[0020] The implementation steps based on Example 1 are as follows: the braided wire is locked on the weft guide 11 through the crochet needle 1, and then transported through the guide roller. The woven cloth is rolled and fitted on both sides through the guide wheel 13 to press the two ends of the cloth. During use, the motor 9 drives the screw 5 to rotate, and the screw 5 pushes the nut 4. Because the lower end of the nut 4 slides on the guide rail 6 through the slider 8, the travel seat 15 is guided by sliding. Because the threads on the outer wall of the screw 5 are relatively distributed, the nut 4 is pushed to move relative to or away from each other, driving the mounting frame 14 to move synchronously. The relative position of the guide wheel 13 is adjusted to adapt to the locking requirements of different widths, avoiding the problem of cloth wear and burrs and pilling caused by extrusion locking, thereby improving the processing quality of the cloth.

[0021] like Figure 1-Figure 4 As shown, the weft joining and locking device for a double rapier loom proposed by the utility model is compared with the first embodiment, and this embodiment also includes: a collecting box 16 is provided at the opposite end of the travel seat 15, a fan 20 is embedded and installed inside the collecting box 16, a suction pipe 18 is installed between the collecting box 16 and the mounting frame 14, a filter screen 17 is provided inside the collecting box 16, and the suction end of the fan 20 is located on one side of the filter screen 17.

[0022] In this embodiment, when both ends of the cloth are in contact with the guide wheel 13, there is still a problem of fluff caused by deficiencies in the processing technology. At this time, the fan 20 is operating, and the suction force acts on the inside of the mounting frame 14 through the suction pipe 18, and the detached fluff is sucked in. The fluff enters the collection box 16, and the filter 17 intercepts the sucked fluff to prevent it from entering the fan 20. A discharge pipe should be set at the lower end of the collection box 16. The discharge pipe is opened and closed by a valve to discharge the collected fluff. The effective treatment of the fluff on the side of the cloth provides assistance for subsequent cleaning work.
