Description

Technical Field

[0001] The utility model relates to the technical field of rapier looms, in particular to a rapier loom transmission mechanism. Background Art

[0002] Rapier loom is a kind of textile machinery equipment used for weaving textiles. It is a traditional loom that uses a rapier to complete the weaving work. Rapier looms usually have multiple rapiers, each of which has one or more weaving heads to shuttle the warp and complete the fabric construction. Compared with other looms, rapier looms have certain advantages in weaving speed, weaving stability and weaving width.

[0003] There will be a spinning thread pay-off structure at the front end of the rapier loom, which is used to transport the rolled defense thread to the rapier loom in sequence. The existing pay-off structure is driven by a chain installed on the main shaft to drive the rubber roller to pull the defense thread for defense thread operation.

[0004] The existing pay-off structure is used for transmission, so that the speed of rotation of the rubber roller is fixed. When different spinning threads are used for pay-off, the deformation caused by the tension applied will be different due to the different materials of the spinning threads, so it is necessary to control different speeds for pay-off. The fixed speed will cause the spinning thread to break, so the machine needs to be stopped to connect the disconnected spinning thread, which reduces the efficiency of processing textiles. Utility Model Content

[0005] The utility model aims to provide a rapier loom transmission mechanism to solve the problem in the background art that a fixed speed may cause yarn breakage, thereby stopping the machine to connect the disconnected yarn and reducing the efficiency of processing textiles.

[0013] By adopting the above technical solution, by meshing one of the gears of the gear set with gear c for transmission, the first rubber shaft and gear a can be rotated together, gear a and gear d can be meshed for transmission, and the first rubber shaft drives the second rubber shaft to rotate synchronously. The synchronous speed can drive the spinning line to perform the pay-off operation, thereby reducing the probability of line breakage caused by asynchronous speed.

Through the cooperation between the above structures, three different speed changes can be realized, so that different spinning threads can control the rotation speed of the first rubber shaft 2 according to the predetermined speed, and the speed can be adjusted without stopping the machine to ensure the working efficiency of processing textiles. The wire-releasing structure 1 includes a first rubber shaft 2 rotatably connected to the inner wall of the wire-releasing structure 1, and one end of the first rubber shaft 2 extends to the outer wall of the wire-releasing structure 1. The first rubber shaft 2 is used to pull the spinning thread forward to release it. The adjusting structure 3 is arranged on the outer wall of the pay-off structure 1, and the adjusting structure 3 has a movable tube 305 and a gear c306 in a horizontal sliding position on the transmission gear shaft 302.

Meshing and speed change, the thread groove 304 is inserted into the moving tube 305 on the outer wall of the transmission gear shaft 302, and the gear c306 is welded on the outer wall of the moving tube 305. The moving tube 305 can move on the transmission gear shaft 302, so that the gear c306 on the moving tube 305 can mesh and change speed with the gear on the corresponding gear set 402. The nut 307 is threadedly connected to the thread groove 304. The two nuts 307 are tightened toward each other and pressed against the two ends of the moving tube 305. The position of the moving tube 305 can be limited after horizontal movement, so as to control the meshing between different gears. The gear b303 can be connected to the power structure gear of the rapier loom through a chain. The gear b303 can be connected to the power structure gear on the rapier loom through the chain. The chain is used to move the gear on the rapier loom.

The adjustment structure 3 also includes a limit groove 308 provided on the outer wall of the transmission gear shaft 302 and a limit tooth 309 welded on the inner wall of the moving tube 305. The limit tooth 309 is clamped in the limit groove 308. Since the moving tube 305 can be horizontally moved on the transmission gear shaft 302, the limit tooth 309 is clamped with the limit groove 308, so that the moving tube 305 can be limited while the limit tooth 309 is clamped and limited to rotate with the transmission gear shaft 302. The transmission structure 4 includes a gear a401 welded at one end of the first rubber shaft 2. The gear a401 is inserted into the outer wall of the first rubber shaft 2 for The gear set 402 is welded and fixed on the outer wall of one end of the first rubber shaft 2.

[0035] Embodiment 3

[0036] See also Figure 3 , gear c306 can be divided into three gears with different diameters. The three gears with different diameters of gear set 402 are arranged in the opposite order to the three gears with different diameters of gear c306. One set of gears is meshed between gear c306 and gear set 402 at a time. The small-diameter gear c306 drives the gear on the large-diameter gear set 402 to reduce the speed of the transmission. The three sets of gears with different diameters can adjust the meshing transmission, so that the structure has three set speeds that can be adjusted, ensuring that the speed can be adjusted according to different spinning lines to avoid line breakage. The nuts 307 at both ends of the moving tube 305 rotate inward in the same direction of tightening. The tightening direction of the nuts 307 is the same as the transmission rotation direction of the transmission gear shaft 302. This structure can make the nuts 307 at both ends rotate inward in the same direction of tightening. 07 must be subjected to the same rotational force in order to move against the moving tube 305. When rotating, it will be subjected to a rotational force in the tightening direction, thereby reducing the problem of moving the moving tube 305 caused by loosening of the nut 307 during rotation, thereby improving the stability of the structure during operation. The gear diameters of gear a401 and gear d404 are the same, and the gear a401 and gear d404 have the same diameter, which can ensure the synchronous rotation of the first rubber shaft 2 and the second rubber shaft 403. All gear teeth on the gear set 402 and gear c306 are the same size, and the gear teeth on the gear set 402 and gear c306 are the same size. Due to the different diameters, the number of teeth will be different. The small diameter gear drives the large diameter gear to achieve a speed reduction effect, and the speed regulation effect can be achieved by cooperating with different groups of gears.

[0037] Working principle: When adjusting the speed, first rotate and move one of the nuts 307 to the bottom of the gear on the corresponding gear set 402, push the moving tube 305 so that one end leans against the nut 307, and the other end of the nut 307 rotates and leans against the other end of the moving tube 305 to fix the moving tube 305, so that the corresponding gear of gear c306 meshes with the gear on the corresponding gear set 402 for transmission. Since the gear set 402 and gear c306 have three groups of gears with different diameters, the transmission ratios when the single gears are meshed are different, thereby achieving the speed adjustment effect.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
