Description

Technical Field

[0001] This utility model belongs to the field of air-jet loom technology, and in particular relates to a protective device for the sheathing linkage of 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. The working principle is to use air as the weft-introducing medium, and the compressed airflow generated by the jet will generate frictional traction force on the weft yarn to pull it through the shed. The jet generated by the airflow achieves the purpose of weft introduction.

[0003] Existing air-jet loom shedding mechanism linkages typically utilize multiple meshing gear components connected to the linkage for transmission, controlling the linkage's rotation. Due to the dispersed arrangement of these meshing components and their prolonged operation, excessive frictional wear occurs, hindering centralized lubrication and impacting their lifespan. Consequently, this affects the lifespan of the linkage connected to these components. Therefore, we provide a protective device for the air-jet loom shedding linkage to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a protective device for the shedding linkage of an air-jet loom. By reciprocating the spraying of oil from a nozzle, the oil is fully sprayed onto the meshing components in the shedding assembly, lubricating the meshing transmission components and thus extending their service life. This, in turn, extends the service life of the shedding linkage connected to the meshing components. This device centrally arranges the meshing transmission components inside the oil box, facilitating synchronous lubrication of the meshing components. It solves the problem that existing air-jet loom multi-arm shedding mechanism linkages typically rely on multiple gear meshing components connected to the linkage for transmission. Due to the dispersed arrangement of the meshing components and their prolonged operation, excessive frictional wear occurs, preventing centralized lubrication and thus affecting the service life of the meshing components and, consequently, the service life of the linkage connected to them.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present utility model.

[0025] For a specific implementation example, please refer to Implementation Example 1. Figure 1-6 This utility model is a protective device for the shedding linkage of an air-jet loom, including an shedding assembly 1; the shedding assembly 1 includes a base 101, and upright plates 102 are symmetrically fixedly connected to the top of the base 101. An mounting plate 103 is fixedly connected to one side of one upright plate 102, and vertical plates 104 are fixedly connected to the top of each upright plate 102. A first rotating shaft 105 is rotatably connected to one side of each vertical plate 104, and a first spur gear 106 is fixedly connected to the end of one first rotating shaft 105 near the mounting plate 103; a drive protection assembly 2 is fixedly fitted to the top of the mounting plate 103, and the drive protection assembly 2 includes an oil box 201 fixedly connected to the top of the mounting plate 103. A first sliding groove 202 is opened on the top of the oil box 201, and a sliding rod 203 is slidably fitted inside the first sliding groove 202.

[0026] An L-shaped plate 204 is fixedly connected to one outer side of the oil box 201. A moving rod 205 is slidably connected through one side of the L-shaped plate 204. A stop plate 206 is fixedly connected to one end of the moving rod 205. A baffle 207 is fixedly connected to the other end of the moving rod 205. A spring 208 sleeved on the moving rod 205 is fixedly connected between the baffle 207 and the L-shaped plate 204. A support rod 209 is fixedly connected to the top of the stop plate 206. A horizontal plate 210 is fixedly connected between the support rod 209 and the sliding rod 203. A conduit 211 is symmetrically fixedly connected through one side of the horizontal plate 210. Several nozzles 212 are evenly connected to the outer periphery of the conduit 211. (Oil is filled into the oil box 201. A pump body is installed at the bottom of the oil box 201. The output end of the pump body 201 is connected to a three-way pipe. A retractable hose is connected between the three-way pipe and the two conduits 211. The pump body provides oil to the nozzles 211.)

[0027] The operation process of this embodiment is as follows: By applying force, the abutment plate 206 is moved towards the L-shaped plate 204 (the spring 208 is stretched), and then the support rod 209 drives the horizontal plate 210 to move the two guide tubes 211 towards the L-shaped plate 204, which in turn drives the nozzle 212 to move towards the L-shaped plate 204. After the abutment plate 206 is no longer under force, under the elastic force of the spring 208, the abutment plate 206 moves away from the L-shaped plate 204. Thus, the support rod 209 drives the horizontal plate 210 to move the two guide tubes 211 away from the L-shaped plate 204, which in turn drives the nozzle 212 to move away from the L-shaped plate 204. This achieves the reciprocating movement of the guide tubes 211 and the nozzle 212. The reciprocating movement of the nozzle 212 sprays oil, which is fully sprayed onto the meshing components in the opening assembly 1, lubricating the meshing transmission components and thus improving the service life of the meshing components, thereby improving the service life of the opening connecting rod connected to the meshing components.

[0028] For a specific embodiment two, please refer to Figure 1-6 Based on the first specific embodiment, the opening assembly 1 further includes a rotating plate 107 fixedly connected to the ends of the two first rotating shafts 105. A slider 108 is symmetrically slidably connected to the bottom of the rotating plate 107. A guide groove 109 is symmetrically opened at the bottom of the rotating plate 107 to slide with the two sliders 108. A connecting rod 110 is hinged to the bottom of the slider 108. A pressure plate 111 is fixedly connected to the bottom end of the connecting rod 110. A guide collar 112 that slides with the two connecting rods 110 is symmetrically fixedly connected to one side of the upright plate 102 near the two connecting rods 110. A fixing rod 113 is symmetrically fixedly connected between the two rotating plates 107.

[0029] The operation process of this embodiment is as follows: by controlling the reciprocating rotation of the first spur gear 106, the first spur gear 106 drives the first rotating shaft 105 to rotate, which in turn drives the rotating plate 107 to rotate. The rotating plate 107 close to the first spur gear 106 drives the rotating plate 107 on the other side to reciprocate synchronously through the two fixed rods 113. During the reciprocating rotation of the rotating plate 107, the rotating plate 107 drives the two pressure plates 111 to move up and down alternately through the two connecting rods 110, providing power for the movement of the pressure plates 111.

[0030] For a specific embodiment three, please refer to Figure 1-6 Based on specific embodiments one and two, the drive protection component 2 further includes a second rotating shaft 213 that is rotatably connected to an outer side of the oil box 201. An L-shaped rod 214 is fixedly connected to one side of the oil box 201 near the second rotating shaft 213. A mounting base 215 is fixedly connected to the top of the L-shaped rod 214. A motor 216 is fixedly connected to the top of the mounting base 215. The output end of the motor 216 is fixedly connected to the second rotating shaft 213. A contact plate 206 is fixedly connected to the circumferential side of the second rotating shaft 213. The cam 217 engages with the first sprocket 218, and the end of the second rotating shaft 213 is fixedly connected to the first sprocket 218. The drive protection assembly 2 also includes a first fixing plate 219 fixedly connected to the bottom of the oil box 201. A first rotating rod 220 is rotatably connected through one side of the first fixing plate 219. A second sprocket 221 is fixedly connected to the circumferential side of the first rotating rod 220. A chain 222 meshes and drives between the first sprocket 218 and the second sprocket 221. A first bevel gear 223 is fixedly connected to both ends of the first rotating rod 220.

[0031] The drive protection assembly 2 also includes a second fixing plate 224 symmetrically fixedly connected to the bottom of the oil box 201. A second rotating rod 225 is rotatably connected through one side of the second fixing plate 224. A second bevel gear 226 is fixedly connected to one end of the second rotating rod 225. The adjacent first bevel gear 223 meshes with the second bevel gear 226. The other ends of the two second rotating rods 225 are fixedly connected to an incomplete gear 227 that meshes with the first straight gear 106. The two incomplete gears 227 are in opposite directions.

[0032] The operation process of this embodiment is as follows: By controlling the motor 216 to drive the second rotating shaft 213 to rotate, the second rotating shaft 213 drives the cam 217 to rotate. The longer end of the cam 217 rotates to contact the abutment plate 206, thereby driving the abutment plate 206 to move closer to the L-shaped plate 204. With the use of the spring 208, power is provided for the reciprocating movement of the abutment plate 206. At the same time, the rotation of the second rotating shaft 213 drives the first sprocket 218 to rotate, and the first sprocket 218 drives the second sprocket through the chain 222. Rotation of 221 causes the second sprocket 221 to drive the first rotating rod 220 to rotate, which in turn drives the two first bevel gears 223 to rotate. The two first bevel gears 223 then drive the two second bevel gears 226 to rotate, which in turn drive the second rotating rod 225 to rotate. The second rotating rod 225 then drives the incomplete gear 227 to rotate. Through the alternating engagement of the two incomplete gears 227 with the first straight gear 106, the first straight gear 206 is driven to rotate reciprocally, providing power for the rotation of the first straight gear 206.
