Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle technology, and in particular to a nozzle for an air-jet loom and an air-jet loom. Background Technology
[0002] Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. Their working principle is to use air as the weft-introducing medium, and the compressed airflow generated by the jet will generate frictional traction force to pull the weft yarn through the shed. The jet of air generated by the nozzle will achieve the purpose of weft introduction.
[0003] In most cases, the nozzles of existing air-jet looms are installed at the shed inlet on the left side of the loom. The weft yarn is then inserted into the nozzle, and the air pipe is connected to the air inlet pipe on the nozzle. The nozzle then emits a high-speed airflow through compressed air to power the flight of the weft yarn, enabling it to fly into the shed quickly and accurately for weaving.
[0004] However, when the air tube injects gas into the nozzle body, the gas will flow back through the air inlet pipe and exert a back thrust on the air tube, causing the connection between the air tube and the air inlet pipe to loosen and fall off, resulting in interruption of gas delivery and affecting the normal supply of yarn. Utility Model Content
[0005] The technical problem this invention aims to solve is that when gas is injected into the nozzle body through the air pipe, the gas will flow back through the air inlet pipe and exert a back thrust on the air pipe, causing the connection between the air pipe and the air inlet pipe to loosen and fall off, resulting in interruption of gas delivery and affecting the normal supply of yarn.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a nozzle for an air-jet loom, including a nozzle body installed on the body of the air-jet loom, an air inlet pipe provided on one side of the nozzle body, a reinforcement device provided on one side of the air inlet pipe to clamp and fix a flexible hose sleeved on the air inlet pipe to prevent the flexible hose from falling off, and a protective device provided on one side of the nozzle body to intercept external objects and prevent objects from colliding with the nozzle body.
[0007] The effect achieved by the above components is as follows: First, the nozzle body is assembled at the shed inlet on the left side of the air jet loom body. Then, the weft yarn is inserted into the nozzle body, and at the same time, the air pipe is sleeved on the surface of the air inlet pipe on the nozzle body. Subsequently, the nozzle body emits a high-speed airflow through compressed air to provide power for the flight of the weft yarn, enabling it to quickly and accurately fly into the shed on one side of the air jet loom body for weaving.
[0008] Preferably, the reinforcement device includes a frame, which is fixedly sleeved on the surface of the air intake pipe. Two electric telescopic rods are symmetrically fixedly connected to the inner wall of the frame. A connecting rod is fixedly connected to the output end of each of the two electric telescopic rods. A round rod is fixedly connected to one side of each of the two connecting rods. A clamp is fixedly connected to the adjacent end of each of the two round rods.
[0009] The effect achieved by the above-mentioned components is as follows: By setting up a reinforcement device, the air tube is first sleeved on the surface of the air inlet pipe, so that the air tube is located between two clamping plates. At this time, the two electric telescopic rods are activated, causing the two electric telescopic rods to move in opposite directions, causing the two connecting rods to move in opposite directions, causing the two round rods to move in opposite directions, causing the two round rods to move in opposite directions, and causing the two clamping plates to move in opposite directions. When the two clamping plates move in opposite directions to the position where they simultaneously squeeze the surface of the air tube, the two clamping plates cooperate with the air inlet pipe to clamp and fix the sleeved air tube, thereby reinforcing the connection between the air tube and the air inlet pipe. This reduces the possibility of the air tube loosening at the connection between the air tube and the air inlet pipe during use, causing the air tube to detach from the surface of the air inlet pipe and disconnect the airflow delivery to the nozzle body, thus improving the stability of the connection between the air tube and the air inlet pipe.
[0010] Preferably, multiple anti-slip strips are fixedly connected to the inner sides of both clamps, and the multiple anti-slip strips are arranged at equal intervals.
[0011] The effect achieved by the above components is that by setting anti-slip strips, the anti-slip strips can increase the friction between the clamp and the surface of the trachea, reducing the possibility of the trachea slipping.
[0012] Preferably, two perforated plates are symmetrically fixedly connected to one side of the frame, and the two perforated plates are respectively fitted onto the surfaces of the two round rods.
[0013] The effect achieved by the above components is that by setting the circular hole plate, the circular hole plate can assist in limiting the circular rod, reducing the shaking of the circular rod and the clamping plate during use.
[0014] Preferably, a sleeve is fixedly connected to one side of the frame, the sleeve is fitted onto the surface of the air intake pipe, and a sealing gasket is provided inside the sleeve.
[0015] The effect achieved by the above components is as follows: by setting up the sleeve, the personnel can move the air tube to the position inside the sleeve for positioning, and at the same time, the sleeve, together with the sealing gasket, assists in sealing the opening of the air tube, reducing the outflow of gas.
[0016] Preferably, the protective device includes a first ring, which is fixedly sleeved on the surface of the nozzle body. A plurality of intercepting rods are fixedly connected to one side of the first ring. A second ring is fixedly connected to one end of the plurality of intercepting rods away from the first ring. A reinforcing ring is fixedly connected to the middle position of the plurality of intercepting rods. Both the second ring and the reinforcing ring are sleeved on the surface of the nozzle body.
[0017] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the first ring is first moved manually, which causes the first ring to drive multiple intercepting rods, reinforcing rings and the second ring to move. When the first ring moves to the position where it is fitted on the surface of the nozzle body, the first ring is welded and fixed to the nozzle body. This allows multiple intercepting rods to wrap around the surface of the nozzle body and intercept external objects, thereby protecting the nozzle body. This reduces the possibility of the nozzle body being accidentally hit by objects during use, causing dents or damage to the surface of the nozzle body, which would affect the normal use of the nozzle body, and improves the safety of the nozzle body in use.
[0018] Preferably, a plurality of rubber blocks are fixedly connected to the inner wall of the second ring, and the surfaces of the plurality of rubber blocks are all in contact with the surface of the nozzle body.
[0019] The effect achieved by the above-mentioned components is that by setting the rubber block, the rubber block can fill the gap between the second ring and the nozzle body, reducing the shaking caused by the force on the second ring.
[0020] Preferably, the air-jet loom employs the air-jet loom body described in any one of the embodiments for mounting the nozzle body.
[0021] The beneficial effects of this utility model are:
[0022] By installing a reinforcement device, the connection between the air pipe and the air inlet pipe can be strengthened, reducing the possibility of the air pipe loosening at the connection point during use, causing the air pipe to detach from the surface of the air inlet pipe and disconnect the airflow to the nozzle body, thus improving the stability of the connection between the air pipe and the air inlet pipe.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Figure 1-4 The nozzle of a jet loom shown includes a nozzle body 1 mounted on the jet loom body 3. An air inlet pipe 2 is provided on one side of the nozzle body 1. A reinforcement device 4 is provided on one side of the air inlet pipe 2 to clamp and fix the hose sleeved on the air inlet pipe 2 and prevent the hose from falling off. A protective device 5 is provided on one side of the nozzle body 1 to intercept external objects and prevent objects from colliding with the nozzle body 1. First, the nozzle body 1 is assembled at the shed inlet on the left side of the jet loom body 3. Then, the weft yarn is inserted into the nozzle body 1. At the same time, the air pipe is sleeved on the surface of the air inlet pipe 2 on the nozzle body 1. Then, the nozzle body 1 emits a high-speed airflow through compressed air to provide power for the flight of the weft yarn, so that it can quickly and accurately fly into the shed on one side of the jet loom body 3 for weaving.
[0032] Figure 2 and Figure 3The reinforcement device 4 shown includes a frame 41, which is fixedly sleeved on the surface of the air intake pipe 2. Two electric telescopic rods 42 are symmetrically fixedly connected to the inner wall of the frame 41. Each of the output ends of the two electric telescopic rods 42 is fixedly connected to a connecting rod 43. A round rod 44 is fixedly connected to one side of each of the two connecting rods 43. A clamping plate 45 is fixedly connected to the adjacent end of each of the two round rods 44. By setting up the reinforcement device 4, the air pipe is first sleeved on the surface of the air intake pipe 2, so that the air pipe is located between the two clamping plates 45. At this time, the two electric telescopic rods 42 are activated, so that the two electric telescopic rods 42 drive the two connecting rods 43 to the surface of the air intake pipe 2. The connecting rod 43 moves in opposite directions, causing the two connecting rods 43 to drive the two round rods 44 to move in opposite directions, causing the two round rods 44 to drive the two clamping plates 45 to move in opposite directions. When the two clamping plates 45 move in opposite directions to the position of simultaneously squeezing the surface of the air pipe, the two clamping plates 45 cooperate with the air inlet pipe 2 to clamp and fix the air pipe, thereby strengthening the connection between the air pipe and the air inlet pipe 2. This reduces the possibility of the air pipe loosening at the connection point with the air inlet pipe 2 during use, causing the air pipe to detach from the surface of the air inlet pipe 2 and disconnect the airflow to the nozzle body 1, thus improving the stability of the connection between the air pipe and the air inlet pipe 2.
[0033] Figure 2 and Figure 3 Multiple anti-slip strips 46 are fixedly connected to the inner sides of the two clamping plates 45 shown. The multiple anti-slip strips 46 are arranged at equal intervals. By setting the anti-slip strips 46, the friction between the clamping plate 45 and the surface of the air tube can be increased, reducing the possibility of the air tube sliding. Two perforated plates 47 are symmetrically fixedly connected to one side of the frame 41. The two perforated plates 47 are respectively fitted onto the surface of the two round rods 44. By setting the perforated plates 47, the perforated plates 47 can provide auxiliary limiting for the round rods 44, reducing the possibility of the round rods 44 and clamping plates 45 shaking during use.
[0034] Figure 2 and Figure 3 A sleeve 48 is fixedly connected to one side of the frame 41 shown. The sleeve 48 is fitted onto the surface of the air inlet pipe 2. A sealing gasket is provided inside the sleeve 48. By setting the sleeve 48, personnel can move the air pipe to the position inside the sleeve 48 for positioning. At the same time, the sleeve 48, together with the sealing gasket, assists in sealing the opening of the air pipe to reduce the outflow of gas.
[0035] Figure 4The protective device 5 shown includes a first ring 51, which is fixedly fitted onto the surface of the nozzle body 1. Multiple intercepting rods 52 are fixedly connected to one side of the first ring 51. A second ring 53 is fixedly connected to the end of each intercepting rod 52 away from the first ring 51. A reinforcing ring 54 is fixedly connected to the middle of each intercepting rod 52. Both the second ring 53 and the reinforcing ring 54 are fitted onto the surface of the nozzle body 1. By setting up the protective device 5, the first ring 51 is first manually moved, causing it to move the multiple intercepting rods 52, the reinforcing ring 54, and the second ring 53. When the first ring 51 moves to the position fitted onto the surface of the nozzle body 1, it is welded and fixed to the nozzle body 1. This allows the multiple intercepting rods 52 to wrap around the surface of the nozzle body 1 and intercept external objects, thus protecting the nozzle body 1. This reduces the risk of the nozzle body 1 being accidentally struck by objects during use, causing dents or damage to its surface and affecting its normal operation, thereby improving the safety of the nozzle body 1.
[0036] Figure 4 The inner wall of the second ring 53 shown is fixedly connected with a plurality of rubber blocks 55. The surfaces of the plurality of rubber blocks 55 are all in contact with the surface of the nozzle body 1. By setting the rubber blocks 55, the rubber blocks 55 can fill the gap between the second ring 53 and the nozzle body 1, reducing the shaking caused by the force on the second ring 53.
[0037] Working principle: First, the nozzle body 1 is assembled at the shed inlet on the left side of the air jet loom body 3. Then, the weft yarn is inserted into the nozzle body 1, and the air pipe is fitted onto the surface of the air inlet pipe 2 on the nozzle body 1. Subsequently, the nozzle body 1 emits a high-speed airflow through compressed air to provide power for the flight of the weft yarn, enabling it to quickly and accurately fly into the shed on one side of the air jet loom body 3 for weaving.
[0038] First, the air tube is fitted onto the surface of the air inlet pipe 2, so that the air tube is positioned between the two clamping plates 45. At this time, the two electric telescopic rods 42 are activated, causing the two electric telescopic rods 42 to drive the two connecting rods 43 to move in opposite directions. The two connecting rods 43 drive the two round rods 44 to move in opposite directions, causing the two round rods 44 to drive the two clamping plates 45 to move in opposite directions. When the two clamping plates 45 move in opposite directions to the position where they simultaneously squeeze the surface of the air tube, the two clamping plates 45 cooperate with the air inlet pipe 2 to clamp and fix the fitted air tube, thereby strengthening the connection between the air tube and the air inlet pipe 2.
[0039] First, manually move the first ring 51 so that the first ring 51 drives multiple intercepting rods 52, reinforcing rings 54 and the second ring 53 to move. When the first ring 51 moves to the position where it is sleeved on the surface of the nozzle body 1, weld the first ring 51 to the nozzle body 1 and fix it in place. This allows the multiple intercepting rods 52 to wrap around the surface of the nozzle body 1 and intercept external objects, thereby protecting the nozzle body 1.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
