Description

Technical Field

[0001] The utility model relates to the field of weaving, and more specifically, it relates to a weft feeding mechanism of a rapier loom. Background Art

[0002] When the rapier of a rapier loom conducts weft insertion, rapier heads and corresponding driving mechanisms are installed on both sides of the loom to drive the rapier heads to reciprocate. These two rapier heads are respectively called the weft feeding rapier and the weft receiving rapier. During weft insertion, the weft feeding rapier and the weft receiving rapier move from both sides of the machine towards the center of the shed. The weft yarn is first held by the weft feeding rapier and sent to the center of the shed. The two rapiers meet at the center of the shed, and then the weft feeding rapier and the weft receiving rapier retreat respectively. During the initial retreat process, the weft yarn is transferred from the weft feeding rapier to the weft receiving rapier, and the weft receiving rapier pulls the weft yarn across the shed. When the two groups of rapier heads of the weft feeding rapier and the weft receiving rapier move, a guide rail is required for guiding to prevent the rapier heads from shifting when moving at high speed.

[0003] When the weft feeding guide rail of the rapier head of a traditional rapier loom is in use, its friction is large and there is no good lubrication assisting component. When the rapier loom operates at high speed for a long time, the guide rail of the weft feeding mechanism wears out relatively quickly, which is not conducive to the stable operation of the loom.

[0004] Based on the above, the purpose of the utility model is to provide a weft feeding mechanism of a rapier loom to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a weft feeding mechanism of a rapier loom. By setting an oil path and multiple groups of lubrication modules on the slide rail, the lubrication modules will use the lubricating oil in the oil path to lubricate the plug and the chute, reducing the wear of the guide rail.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A weft feeding mechanism of a rapier loom includes a weft feeding rapier, a weft receiving rapier, and a driving mechanism that respectively drives the weft feeding rapier and the weft receiving rapier to move. Sliders are arranged at the lower ends of the weft feeding rapier and the weft receiving rapier. A slide rail is arranged between the two side sliders. The driving mechanism drives the sliders to reciprocate along the slide rail. Plug blocks are arranged on both sides of the sliders. A chute for the plug blocks to insert and move is arranged on the slide rail. Both the plug blocks and the chute are trapezoid-shaped. An oil path is arranged on the slide rail, and several lubrication modules are arranged on the oil path. The lubrication modules can lubricate the chute and the plug blocks.

[0007] By adopting the above technical solutions, when weaving operations are carried out, the driving mechanism drives the two side sliders to drive the weft feeding rapier and the weft receiving rapier to operate respectively. During this process, the lubrication modules will use the lubricating oil in the oil path to lubricate the plug blocks and the chute, reducing the wear of the guide rail.

[0008] The present utility model is further configured as follows: The lubrication module includes an oil storage tank communicated with an oil passage. A conveying tank with one end communicated with the oil storage tank is arranged on the oil storage tank. The other end of the conveying tank is provided with a plurality of dispersion tanks with one end communicated with the conveying tank. The other end of the dispersion tank extends into the sliding groove and is fixedly connected with a sponge plug. A plunger is slidably connected in the oil storage tank. A pressing plate is fixedly connected to the plunger. A plurality of sliding rods are arranged on the pressing plate. Both the pressing plate and the sliding rods are slidably connected with a sliding rail. A spring is sleeved on the sliding rod. One-way valves are arranged between the oil passage and the oil storage tank and between the oil storage tank and the conveying tank. The one-way valves prevent the oil storage tank from delivering liquid to the oil passage and the conveying tank from delivering liquid to the oil storage tank.

[0009] The present utility model is further configured as follows: The lubrication modules on both sides of the oil passage are arranged in a staggered manner.

[0010] The present utility model is further configured as follows: Guardrails are arranged on both sides of the sliding rail, and an oil collecting tank is arranged inside the guardrails.

[0011] The present utility model is further configured as follows: A recovery pipe is arranged on the sliding rail. Recovery grooves with one end communicated with the recovery pipe are respectively arranged on both sides of the recovery pipe. The other ends of the two recovery grooves are respectively communicated with the two oil collecting tanks.

[0012] The present utility model is further configured as follows: A plurality of universal balls are arranged on the plug block.

[0013] In summary, the present utility model has the following beneficial effects:

[0014] By arranging an oil passage and multiple groups of lubrication modules on the sliding rail, during the weft feeding operation, the slider will squeeze the pressing plate through the universal balls, causing the pressing plate to drive the plunger to push the lubricating oil in the oil storage tank into the conveying tank, and then through the dispersion tank to the sliding groove. The sponge plug will play a role in buffering and slowly oozing out the lubricating oil. The oozing lubricating oil will gradually slide along the trapezoidal inner wall of the sliding groove, thereby playing a role in lubricating the universal balls and the sliding groove, reducing the wear of the guide rail. The guardrail can prevent the lubricating oil from splashing out and polluting the yarn. The oil collecting tank and the recovery pipe can recover the lubricating oil, which is convenient for the user to clean. Description of the Drawings

[0023] A weft insertion mechanism for a rapier loom, such as Figures 1-3As shown, it includes a weft inserting sword, a weft receiving sword, and a driving mechanism (not shown in the figure) that respectively drives the weft inserting sword and the weft receiving sword to move. Sliders 1 are provided at the lower ends of the weft inserting sword and the weft receiving sword. The weft inserting sword and the weft receiving sword are respectively fixed on the two side sliders 1. A slide rail 2 is provided between the two side sliders 1. The two side sliders 1 are both slidably connected to the slide rail 2. The slide rail can be installed on the loom frame through tools such as bolts. The driving mechanism will drive the slider 1 to reciprocate along the slide rail 2. Insert blocks 3 are formed on both sides of the slider 1. A chute 4 for the insert block 3 to insert and move is formed on the slide rail 2. Both the insert block 3 and the chute 4 are trapezoidal. In this embodiment, the insert block 3 and the chute 4 are isosceles trapezoids. An oil passage 5 is formed on the slide rail 2. A number of lubrication modules are provided on the oil passage 5. The lubrication modules can lubricate the chute 4 and the insert block 3. The oil passage is connected to an external lubricating oil storage device.

[0024] Further, the lubrication module 20 includes an oil storage tank 6 communicated with the oil passage 5. A delivery tank 7 is provided at one end of the oil storage tank 6 and communicated with it. A number of dispersion tanks 8 are provided at the other end of the delivery tank 7 and communicated with it at one end. The other end of the dispersion tank 8 extends into the chute 4 and is fixedly connected with a sponge plug 9. A plunger 10 is slidably connected in the oil storage tank 6. A pressing plate 11 is fixedly connected to the plunger 10. A number of sliding rods 12 are fixedly connected to the pressing plate 11. Both the pressing plate 11 and the sliding rods 12 are slidably connected to the slide rail 2. The side of the pressing plate 11 away from the sliding rods is arc-shaped. A spring 13 is sleeved on the sliding rod 12. One-way valves 14 are installed between the oil passage 5 and the oil storage tank 6, and between the oil storage tank 6 and the delivery tank 7. The one-way valves 14 prevent the oil storage tank 6 from delivering liquid to the oil passage 5 and the delivery tank 7 from delivering liquid to the oil storage tank 6.

[0025] Further, the lubrication modules on both sides of the oil passage 5 are staggeredly distributed.

[0026] Further, guardrails 15 are fixedly connected to both sides of the slide rail 2. An oil collecting tank 16 is provided inside the guardrails 15.

[0027] Further, a recovery pipe 17 is formed on the slide rail 2. Recovery grooves 18 are provided at both ends of the recovery pipe 17 and communicated with it at one end. The other ends of the two side recovery grooves 18 are respectively communicated with the two side oil collecting tanks 16.

[0028] Further, a number of universal ball bearings 19 are installed on the insert block 3.

[0029] Working principle: When weaving, the driving mechanism drives the sliders 1 on both sides to drive the weft insertion sword and the weft receiving sword to reciprocate (the driving mechanism for driving the weft insertion sword and the weft receiving sword to reciprocate is a mature existing technology and will not be elaborated here). During this process, the universal balls 19 will reduce the friction between the insertion block 3 and the chute 4. When the slider 1 moves, it will also squeeze the pressure plate 11 through some of the universal balls 19, causing the pressure plate 11 to drive the plunger 10 to push the lubricating oil in the oil storage tank 6 into the conveying groove 7, and then through the dispersion groove 8 to the chute 4. The sponge plug 9 will play a role in buffering and slowly oozing the lubricating oil. The flowing lubricating oil will gradually slide along the trapezoidal inner wall of the chute 4, thereby playing a role in lubricating the universal balls 19 and the chute 4 and reducing the wear of the guide rail.

[0030] After the slider 1 slides away, the pressure plate 11 and the plunger 10 will reset under the action of the spring 13. At this time, a vacuum suction force is generated in the oil storage tank 6, and then the lubricating oil in the oil path 5 is sucked into the oil storage tank 6, and then the oil supply to the chute 4 is carried out in a cycle. The guardrail 15 can prevent the lubricating oil from splashing out and polluting the yarn. The oil collecting tank 16 and the recovery pipe 17 can recover the lubricating oil, which is convenient for the user to clean.

[0031] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
