Description
Technical Field
[0001] The utility model belongs to the technical field of rapier looms, and in particular relates to a waste-free edge control mechanism for rapier looms. Background Art
[0002] The rapier loom is the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation and high-efficiency production of shuttleless looms, its active weft insertion method has strong variety adaptability and can adapt to the weft insertion of various types of yarns. In addition, the rapier loom also has obvious advantages in multi-color weft weaving and can produce color-dyed products with up to 16 colors of weft yarn.
[0003] During the processing of the rapier loom, the weft yarn needs to be passed horizontally through the warp yarn through the cloth mouth for weaving, and the weft yarn needs to be cut to a fixed length during weaving. Due to the lack of support at both ends of the weft yarn after cutting, it will droop, forming waste edges after weaving, which need to be cut later, resulting in waste. Utility Model Content

[0019] 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.
[0020] See also Figure 1-4The utility model provides a waste-free edge control mechanism for a rapier loom, comprising a thread trimming platform 1, on which a thread trimming port 2 facing backward is arranged; a thread control mechanism is arranged on the left side of the thread trimming platform 1, and the thread control mechanism comprises a suction tube 3, a thread control clamping nozzle 4 and an air port 5, wherein the thread control clamping nozzle 4 closes the bottom end of the suction tube 3, and the thread control clamping nozzle 4 is in a mouth shape opened up and down, and a horizontal long clamping groove 6 is arranged in the middle, and the air port 5 is arranged on the clamping groove 6; a conductor rod 7 is arranged on the left side of the rear of the thread trimming platform 1, The bottom end of the conductor rod 7 is provided with a conductor head 8, and the conductor head 8 is provided with a conductor hole 9; a wire pressing rod 10 is provided on the right side of the rear of the wire cutting platform 1, and the top of the wire pressing rod 10 is in the shape of a hook bent forward; a wire feeding mechanism 11 is provided at the rear of the wire cutting platform 1, and an openable wire clamping port 12 is provided at the right end of the wire feeding mechanism 11; during weaving, the suction pipe 3 generates suction inside by connecting to an external suction mechanism, and generates suction at the air port 5 of the wire control clamping nozzle 4, so that the end of the yarn introduced through the conductor hole 9 is fed into the suction pipe 3, and the suction pipe 3 is connected to the external suction mechanism, and the suction pipe 3 ... The wire rod 7 drives the wire head 8 to descend and press the yarn, and the yarn is located at a moderate height on the right side of the wire feeding mechanism 11. Then the wire clamping mouth 12 opens to clamp the yarn, and the wire control clamping mouth 4 releases the yarn end. The wire feeding mechanism 11 drives the yarn to the other side through the driving mechanism to interweave with the warp. At the same time, when the length is appropriate, the wire pressing rod 10 is driven by the driving mechanism to rotate forward to press the yarn, and the yarn is cut by the blade of the wire cutting mouth 2 on the wire cutting table 1. At this time, the wire control clamping mouth 4 generates suction and is combined with the warp yarn. One end of the interwoven yarn at the thread cutting table 1 is in a straight state under suction, and there is no waste edge after weaving. When the yarn introduced at 9 is cut, the end is sucked by the thread control clamp 4, and the same principle is repeated to weave one side without waste edge, and a small amount of waste edge will be produced on the other side. This is because although the thread clamping mouth 12 is close to the thread control clamp 4, the end of the yarn is adsorbed and controlled at the air port 5, and the position clamped by the thread clamping mouth 12 is very far from the air port 5 and lacks control. This distance will sag during weaving to produce a small amount of waste edge.
[0021] Specifically, a mounting plate 13 is welded on the suction tube 3, and a strip-shaped mounting hole 14 is opened on the mounting plate 13; in this embodiment, the suction tube 3 is conveniently installed on the rapier loom through the mounting plate 13, and the strip-shaped mounting hole 14 is conveniently adjusted to fix the position with the bolt.
[0022] Specifically, the thread cutting mouth 2 is provided with blades at the top and bottom, and the mouth is gradually reduced from the outside to the inside. In this embodiment, the thread pressing rod 10 is driven forward by the driving mechanism to press the yarn, which is conducive to entering the blade that gradually reduces from the outside to the inside and cutting the yarn.
[0023] Specifically, the air opening 5 is a long strip structure; in this embodiment, the design of the long strip air opening 5 can prevent the air opening 5 from being completely blocked when the yarn end is sucked.
[0024] Specifically, the edge of the wire hole 9 is a non-angular structure; in this embodiment, the edges are prevented from cutting the yarn.
[0025] Specifically, the outer edge of the thread pressing rod 10 is a structure without edges and corners, and the surface is not smooth; in this embodiment, the edges and corners are prevented from cutting the yarn, and a certain friction force is provided to facilitate accurately pressing the thread to the set position.
[0026] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0027] Working principle: During weaving, the suction tube 3 generates suction inside by connecting to the external suction mechanism, and generates suction at the air port 5 of the thread control clamping nozzle 4, sucking and controlling the end of the yarn led through the wire hole 9, and then the wire rod 7 drives the wire head 8 to descend to press down the yarn, and makes the yarn at a moderate height on the right side of the wire feeding mechanism 11, and then the wire clamping port 12 opens to clamp the yarn, and the yarn end is released at the thread control clamping nozzle 4, and the wire feeding mechanism 11 drives the yarn to the other side through the driving mechanism to interweave with the warp. At the same time, when the length is appropriate, the wire pressing rod 10 is driven by the driving mechanism to rotate forward to press the yarn, and after the wire cutting, The blade of the thread cutting mouth 2 on the table 1 cuts the yarn, and at this time the thread control clamp 4 generates suction, and one end of the yarn interwoven with the warp yarn at the thread cutting table 1 is in a straight state under the suction, and there is no waste edge after weaving, and when the yarn introduced at the wire hole 9 is cut, the end is sucked by the thread control clamp 4, and the same principle is repeated to weave without waste edge on one side, and a small amount of waste edge will be generated on the other side. This is because although the thread clamping mouth 12 is close to the thread control clamp 4, the end of the yarn is adsorbed and controlled at the air port 5, and the position clamped by the thread clamping mouth 12 is very small and lacks control from the air port 5. This distance will sag during weaving to produce a small amount of waste edge.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
