Their weft insertion method is reasonable, the weft insertion rate is high, the operation is simple and safe, and they have the advantages of wide adaptability, low material consumption, high efficiency, high speed and low noise. They have become one of the most promising new looms.

[0003] The air jet loom consists of an air jet system, a loom frame, a heald drying and wetting system, a fabric pick-up and delivery mechanism, and a control system. The air jet system is responsible for spraying air onto the fabric. The loom frame is the supporting structure of the air jet loom. The heald drying and wetting system is used to process the heald to prevent it from being too dry or too wet and affecting the quality of the fabric. The fabric pick-up and delivery mechanism is used to store and deliver the fabric, usually including a winding mechanism and a feeding mechanism. The control system is used to control the operation of various parts and coordinate the entire machine. However, the drive components and control components of the existing air jet loom are located inside the machine body. During maintenance, it is necessary to use a screwdriver to remove the external screws and then open the corresponding shell, which is cumbersome and inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide an air jet loom that is easy to maintain, so as to solve the problem in the above background art that when maintaining the air jet loom, a screwdriver must be used to remove the external screws and then open the corresponding housing, which is a cumbersome and inconvenient operation.

[0005] To achieve the above object, the present invention provides the following technical solutions: an air jet loom that is easy to maintain, comprising an air jet loom body, a mounting frame and a fabric taking and delivering assembly,

[0006] Mounting frames are provided on both sides of the air-jet loom body, a fabric picking-up and delivery assembly and a heald yarn drying and lubricating assembly are provided inside the mounting frame, a driving assembly and a control assembly are provided on one side of the mounting frame, a mounting plate is connected to the side of the mounting frame away from the fabric picking-up and delivery assembly and the heald yarn drying and lubricating assembly, protective shells are provided on both sides of the mounting plate, an unfolding mechanism is provided inside the protective shell, and the unfolding mechanism consists of a driving motor, a driving gear, a transmission gear, a bidirectional threaded rod, an internal threaded rod and a sliding groove.

[0007] Preferably, a driving motor is mounted on one side of the mounting plate via a locking bolt, a driving gear is mounted on one end of the driving motor via a coupling, and the outer side of the driving gear is meshed with the transmission gear.

[0008] Preferably, a bidirectional threaded rod is connected to the middle of the transmission gear, the outer side of the bidirectional threaded rod is inserted through the mounting plate, and both sides of the bidirectional threaded rod are threadedly connected to the internal threaded rod through threads.

[0009] Preferably, one end of the internal threaded rod away from the mounting plate is connected to the protective shell on an adjacent side, and sliding grooves are symmetrically opened inside the mounting frame, and both sides of the protective shell are slidably connected to the sliding grooves.

[0010] Preferably, a first heat dissipation net is installed in the slot opened inside the protective shell, a second heat dissipation net is provided on one side of the first heat dissipation net, a connecting frame is connected to the outer side of the second heat dissipation net, and the bottom of the connecting frame is rotatably connected to the mounting frame through a rotating shaft.

[0011] Preferably, a steering mechanism is provided on one side of the second heat dissipation net, the steering mechanism is composed of a push rod, a limiting slide groove and a return spring, and the limiting slide grooves are provided inside the four protective shells.

[0012] Preferably, one side of the connecting frame is rotationally connected to one end of the push rod, and the other end of the push rod is slidingly connected to the protective shell on the adjacent side through a limiting slide groove. A return spring is connected inside the limiting slide groove, and one end of the return spring is connected to the push rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the air-jet loom is easy to maintain, and the driving motor controls the start-up driving gear, the transmission gear and the bidirectional threaded rod to rotate through the coupling. When the bidirectional threaded rod rotates, the protective shell is pushed to both sides through the action of the outer thread and the inner thread of the rod, which solves the problem of needing to use a screwdriver to remove the external screws and then open the corresponding shell during maintenance of the air-jet loom, which is cumbersome and inconvenient.

[0014] 1. This easy-to-maintain air jet loom is designed to facilitate quick inspection of the drive components and control components on both sides of the mounting frame. The operator turns on the drive motor through the outer control panel. The drive motor starts the drive gear through the coupling control. When the drive gear rotates, the outer side engages with the transmission gear, driving the transmission gear and the bidirectional threaded rod installed in the middle to rotate. When the bidirectional threaded rod rotates, the outer thread and the inner thread of the rod act to push the protective housing to both sides, exposing the drive components and control components. This easy-to-maintain air jet loom is equipped with an unfolding mechanism, which can quickly open the protective housing to both sides for easy inspection and convenient operation.

[0015] 2. The air-jet loom is easy to maintain. A single-layer heat dissipation net is used to dissipate heat from the working components inside the air-jet loom body. The single-layer heat dissipation net cannot intercept external dust more thoroughly, but the double-layer heat dissipation setting is not convenient for cleaning the heat dissipation net. Therefore, a second heat dissipation net is rotatably installed inside the mounting frame through a rotating shaft and a connecting frame to strengthen the filtration of dust in the air. At the same time, one side of the connecting frame is slidably connected to the protective shell through a push rod and a limiting slide. When the protective shell is unfolded to both sides, one end of the limiting slide will pull one end of the push rod, thereby driving the second heat dissipation net and the connecting frame to flip. The air-jet loom is easy to maintain and is provided with a double-layer heat dissipation net, and the second heat dissipation net can move accordingly with the operation of the unfolding mechanism, which is convenient to use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 The utility model provides a technical solution: an air jet loom that is easy to maintain, comprising an air jet loom body 1, a mounting frame 2 and a fabric taking and delivering assembly 201.

[0023] Mounting frames 2 are provided on both sides of the air-jet loom body 1, and a fabric picking-up and delivery assembly 201 and a heald yarn drying and wetting assembly 202 are provided inside the mounting frame 2. A driving assembly 203 and a control assembly 204 are provided on one side of the mounting frame 2. A mounting plate 3 is connected to the side of the mounting frame 2 away from the fabric picking-up and delivery assembly 201 and the heald yarn drying and wetting assembly 202. Protective shells 4 are provided on both sides of the mounting plate 3, and an unfolding mechanism 5 is provided inside the protective shell 4. The unfolding mechanism 5 consists of a driving motor 501, a driving gear 502, a transmission gear 503, a bidirectional threaded rod 504, an internal threaded rod 505 and a sliding groove 506.

[0024] A driving motor 501 is installed on one side of the mounting plate 3 through a locking bolt, and a driving gear 502 is installed on one end of the driving motor 501 through a coupling. The outer side of the driving gear 502 is meshed with the transmission gear 503, and a bidirectional threaded rod 504 is connected to the middle of the transmission gear 503. The outer side of the bidirectional threaded rod 504 is inserted through the mounting plate 3, and both sides of the bidirectional threaded rod 504 are threadedly connected to the internal threaded rod 505 through threads. The end of the internal threaded rod 505 away from the mounting plate 3 is connected to the protective shell 4 on the adjacent side, and sliding grooves 506 are symmetrically opened inside the mounting frame 2, and the two sides of the protective shell 4 are slidably connected to the sliding grooves 506.

[0025] During specific implementation, in order to facilitate the staff to quickly inspect the drive components 203 and control components 204 on both sides of the mounting frame 2, the staff controls to open the drive motor 501 through the outer control panel. The drive motor 501 starts the rotation of the drive gear 502 through the coupling control. When the drive gear 502 rotates, the outer side engages with the transmission gear 503, driving the transmission gear 503 and the two-way threaded rod 504 installed in the middle to rotate. When the two-way threaded rod 504 rotates, the protective shell 4 is pushed to both sides through the action of the outer thread and the inner thread rod 505 thread, exposing the drive component 203 and the control component 204 for easy inspection by the staff. At the same time, the two sides of the protective shell 4 are slidably connected to the mounting frame 2 through the sliding groove 506, which can improve the stability of the protective shell 4 when moving. The air-jet loom that is easy to maintain is provided with an unfolding mechanism 5, which can quickly open the protective shell 4 to both sides for easy work and maintenance, and is easy to operate.

[0026] See Figure 3 and Figure 4It can be seen that a first heat dissipation net 6 is installed in the slot opened inside the protective shell 4, a second heat dissipation net 7 is provided on one side of the first heat dissipation net 6, a connecting frame 701 is connected to the outside of the second heat dissipation net 7, the bottom of the connecting frame 701 is rotatably connected to the mounting frame 2 through a rotating shaft, a steering mechanism 8 is provided on one side of the second heat dissipation net 7, the steering mechanism 8 is composed of a push rod 801, a limiting slide groove 802 and a return spring 803, four limiting slide grooves 802 are opened inside the protective shell 4, one side of the connecting frame 701 is rotatably connected to one end of the push rod 801, and the other end of the push rod 801 is slidably connected to the protective shell 4 on the adjacent side through the limiting slide groove 802, a return spring 803 is connected inside the limiting slide groove 802, and one end of the return spring 803 is connected to the push rod 801.

[0027] In specific implementation, a single-layer heat dissipation net is used for heat dissipation of the working components inside the air-jet loom body 1. The single-layer heat dissipation net cannot intercept external dust more thoroughly, but the double-layer heat dissipation setting is not convenient for cleaning the heat dissipation net. Therefore, the second heat dissipation net 7 is rotatably installed inside the mounting frame 2 through the rotating shaft and the connecting frame 701 to strengthen the filtering of dust in the air. At the same time, one side of the connecting frame 701 is slidably connected to the protective shell 4 through the pushing rod 801 and the limiting slide 802. When the protective shell 4 is unfolded to both sides, one end of the limiting slide 802 will pull one end of the pushing rod 801, thereby driving the second heat dissipation net 7 and the connecting frame 701 to flip over, which is convenient for maintenance work. When the protective shell 4 is closed, the return spring 803 in the limiting slide 802 will drag the pushing rod 801 to reset the second heat dissipation net 7, so that the second heat dissipation net 7 can carry out dust removal work. The air-jet loom that is easy to maintain is provided with a double-layer heat dissipation net, and the second heat dissipation net 7 can move accordingly with the operation of the unfolding mechanism 5, which is convenient to use.

[0028] To sum up, when using the air-jet loom that is easy to maintain, the control component 204 controls the start drive component 203 to make the air-jet loom body 1 work. When the air-jet loom body 1 is working, air is used as the weft insertion medium, and the compressed air flow ejected from the heald drying and wetting component 202 and the fabric picking and feeding component 201 generates friction traction on the weft yarn to pull the weft yarn, and the weft yarn is brought through the shed, and the purpose of weft insertion is achieved by the jet generated by the air jet. When the air-jet loom body 1 is overhauled, the start drive motor 501 controls the start drive gear 502, the transmission gear 503 and the bidirectional threaded rod 504 to rotate through the coupling. When the bidirectional threaded rod 504 rotates, the protective shell 4 is pushed to both sides by the action of the outer thread and the inner thread rod 505 thread.
