Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and relates to an air-jet loom, in particular to a waste edge yarn treatment device for an air-jet loom. Background Technique

[0002] An air-jet loom mainly consists of a shedding mechanism, an air-jet weft insertion mechanism, a beating-up mechanism, a warp let-off mechanism, a take-up mechanism and other auxiliary mechanisms. Its working principle is roughly as follows: The shedding mechanism drives the heddle frames to move up and down, so that the warp yarns form a shed. The weft insertion mechanism uses air as the weft insertion medium, and the compressed air jet generates frictional traction on the weft yarn to traction it, bringing the weft yarn into the shed, and then the beating-up mechanism drives the reed to beat the weft yarn entering the shed into the cloth fell to form cloth.

[0003] The existing air-jet looms have the following problems:

[0004] 1. When an air-jet loom weaves cloth, since it cannot suck the end of the weft yarn, the waste edge yarn of the woven cloth is relatively long, and the tightness of the cloth cannot be quickly observed, resulting in poor quality of the woven cloth;

[0005] 2. When an air-jet loom weaves cloth, it is necessary to manually cut the weft yarn, which makes the weaving work less convenient and the efficiency of weaving cloth is low. Content of the Utility Model

[0006] In order to solve the technical problems in the background technique, the utility model proposes a waste edge yarn treatment device for an air-jet loom, which solves the problems of long waste edge yarn, inability to be tensioned and cumbersome shearing operation in the existing technology, and greatly improves the efficiency and quality of the woven cloth.

[0007] The purpose of the utility model can be realized by the following technical solutions:

[0008] A waste edge yarn treatment device for an air-jet loom, the waste edge yarn is the end of the weft yarn after the drawing nozzle traction weft yarn enters the shed formed by the warp yarns and forms the cloth surface through the reed beating-up. The drawing nozzle and the reed are both installed on the frame of the air-jet loom. The waste edge yarn treatment device includes a suction mechanism and a shearing mechanism installed on the frame. The suction mechanism is arranged on one side of the drawing nozzle to suck the waste edge yarn at the edge of the cloth surface, and the shearing mechanism is arranged between the suction mechanism and the cloth surface to cut off the waste edge yarn at the edge of the cloth surface.

[0009] Furthermore, the suction mechanism includes a suction chamber fixedly installed on the frame and a suction motor arranged on one side of the suction chamber. The suction motor is communicated with the suction chamber through a suction pipe.

[0010] Further, the air suction cavity adopts a horn-shaped structure. One side of the air suction cavity is connected to the air suction pipe, and the other side is provided with an air suction port. One end of the air suction port is flush with the stretching nozzle, and the other end is flush with the shearing mechanism.

[0011] Further, a collection cavity is provided in the middle of the air suction pipe. One side of the collection cavity is connected to the waste edge yarn collection barrel through a collection pipe, and the other end is connected to the air inlet motor through an air inlet pipe.

[0012] Further, a filter screen is provided in the air suction pipe, and the filter screen is arranged between the collection cavity and the air suction motor.

[0013] Further, the shearing mechanism includes a knife pad fixedly installed on the frame and a knife rest installed above the knife pad. A shearing knife is movably connected to the knife rest, and the shearing knife is driven by a cylinder to move up and down along the knife rest to cut the passing waste edge yarn on the lower knife pad.

[0014] Further, knife grooves adapted to the shearing knife are provided on the knife pad.

[0015] The beneficial effects of the present utility model: The waste edge yarn treatment device for air-jet looms provided by this application solves the problems of long waste edge yarn, inability to tension, and cumbersome shearing operation in the prior art by setting an air suction mechanism on one side of the stretching nozzle to hold the waste edge yarn at the edge of the cloth surface and tension the waste edge yarn that has separated from the cloth edge, and by setting a shearing mechanism between the air suction mechanism and the cloth surface to automatically cut the waste edge yarn passing through the shearing mechanism, greatly improving the efficiency and quality of the woven fabric. By covering the suction range of the air suction mechanism to the installation position of the shearing mechanism, the chips generated when the shearing mechanism cuts the waste edge yarn can be removed in real time, avoiding the chips being carried away by the reserved feather edge section of the cloth surface or accumulating around the shearing mechanism, improving the machine platform environment and production quality. By sending the cut waste edge yarn and the chips generated by shearing into the waste edge yarn collection barrel through the air suction mechanism, the recovery of the waste edge yarn and chips is completed.

[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 of 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] like Figure 1 As shown, during the weaving process of the air jet loom, the warp yarn 32 is driven by the opening mechanism to move the heald frame up and down, so that the warp yarn 32 forms a shed, and the weft yarn 31 is pulled by the compressed air flow ejected by the extension nozzle 21 installed on the frame 1 of the air jet loom, enters the warp yarn 32 to form a shed, and then the reed 22 installed on the frame 1 of the air jet loom is driven by the beating mechanism to beat the weft yarn 31 entering the shed into the weaving mouth to weave the cloth surface 6. After the beating action is completed, at the edge of the formed cloth surface 6, the total length of the weft yarn 31 separated from the cloth edge is about 80-100mm, and the glass fiber The cloth surface 6 generally has a reserved feather edge length of about 3-5 mm, and the excess part will be cut off as waste yarn. The utility model provides a waste yarn processing device for an air jet loom, including a suction mechanism 4 and a shearing mechanism 5 installed on a frame 1. The suction mechanism 4 is arranged on one side of the extension nozzle 21 to suck the waste yarn at the edge of the cloth surface 6, and tighten the right end of the weft yarn 31 separated from the cloth edge to facilitate shearing by the shearing mechanism 5. The shearing mechanism 5 is arranged between the suction mechanism 4 and the cloth surface 6 to cut off the waste yarn at the edge of the cloth surface 6, and tiny chips will be generated during the shearing process.

[0021] like Figure 2 As shown, the suction mechanism 4 includes a suction chamber 41 fixedly mounted on the frame 1 and a suction motor 42 arranged on one side of the suction chamber 41, and the suction motor 42 is connected to the suction chamber 41 through a suction pipe 43. The suction chamber 41 adopts a trumpet-shaped structure, one side of the suction chamber 41 is connected to the suction pipe 43, and the other side is provided with a suction port, one end of the suction port is flush with the extension nozzle 21, and the other end is flush with the shearing mechanism 5, and the suction range of the suction port is about 160mm, so that the suction range of the suction mechanism 4 covers from the steel reed 22 to the rearmost position (i.e., the maximum opening position of the warp yarn) to the installation position of the shearing mechanism 5, and the chips generated when the shearing mechanism 5 shears the waste yarn can be removed in real time, avoiding the chips being carried away by the feather edge section reserved by the cloth surface 6 or accumulated around the shearing mechanism 5, thereby improving the machine environment and production quality.

[0022] In the middle of the air suction pipe 43, there is a collection cavity 44. One side of the collection cavity 44 is connected to the waste edge yarn collection barrel 46 through a collection pipe 45, and the other end is connected to the air inlet motor 48 through an air inlet pipe 47. A filter net 49 is arranged in the air suction pipe 43, and the filter net 49 is set between the collection cavity 44 and the air suction motor 42. Both the air suction motor 42 and the air inlet motor 48 adopt scroll blowers. The waste edge yarn cut by the shearing mechanism 5 and the chips generated by shearing are sucked into the air suction cavity 41 from the air suction port, then enter the collection cavity 44 through the air suction pipe 43, and stay in the collection cavity 44 due to the blockage of the filter net 49. Finally, the waste edge yarn and chips in the collection cavity 44 are driven by the air inlet motor 48 and enter the waste edge yarn collection barrel 46 through the collection pipe 45 to complete the recovery of the waste edge yarn and chips.

[0023] As Figure 3 shown, the shearing mechanism 5 includes a knife pad 51 fixedly installed on the frame 1 and a knife rest 52 installed above the knife pad 51. A shearing knife 53 is movably connected to the knife rest 52. The waste edge yarn tensioned by the suction of the air suction mechanism 4 passes through between the shearing knife 53 and the knife pad 51 in sequence. The shearing knife 53 is driven by a cylinder 54 to move up and down along the knife rest 1 to cut the passing waste edge yarn on the lower knife pad 51. A knife groove 55 adapted to the shearing knife 53 is formed on the knife pad 51 to improve the efficiency and stability of cutting the waste edge yarn.

[0024] The working process of the utility model: First, the weft yarn 31 enters the warp yarn 32 under the traction of the compressed air flow of the drawing nozzle 21 to form a shed. The reed 22 beats the weft yarn 31 entering the shed into the fabric surface 6 to weave the fabric. One end of the waste edge yarn that forms and detaches from the fabric edge on the fabric surface 6 is sucked into the air suction cavity 41 under the action of the air suction motor 42. The waste edge yarn is tensioned due to the suction and passes through between the shearing knife 53 and the knife pad 51 in sequence. The shearing knife 53 is driven by a cylinder 54 to move up and down along the knife rest 1 to cut the passing waste edge yarn on the lower knife pad 51. The cut waste edge yarn and the chips generated by shearing are sucked into the air suction cavity 41 from the air suction port, then enter the collection cavity 44 through the air suction pipe 43, and stay in the collection cavity 44 due to the blockage of the filter net 49. Finally, the waste edge yarn and chips in the collection cavity 44 are driven by the air inlet motor 48 and enter the waste edge yarn collection barrel 46 through the collection pipe 45 to complete the recovery of the waste edge yarn and chips.
