Technical Field

[0001] The present invention relates to the technical field of textile machinery, and particularly relates to a loom take-up device with a damping function. Background Art

[0002] In the existing take-up of a loom, since there is only an active drive part and a multi-group gear drive is adopted, there will be some meshing clearances. When weaving some fabrics, during the beating-up or shedding motion, the warp shed will shake to a certain extent, and the tension of the fabric surface between the warp shed and the take-up roller will change, sometimes completely slack. The meshing force between the gears of the take-up drive changes repeatedly, resulting in shaking, generating noise, accelerating wear, and affecting the fabric quality. Therefore, the existing technology urgently needs to be further improved. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned existing technology, the purpose of the present invention is to provide a loom take-up device with a damping function, which solves the problems that the meshing force between the gears of the take-up drive changes repeatedly, resulting in shaking, noise, accelerating wear, and affecting the fabric quality.

[0028] The present invention will be described in detail below with reference to the drawings:

[0029] Example 1, in combination with Figure 1 and Figure 2 , a loom take-up device with a damping function includes a left wallboard 101, a right wallboard 102, a take-up roller 103, a driving mechanism and a damping mechanism. The left wallboard 101 and the right wallboard 102 are arranged opposite to each other, one on the left and the other on the right, and the take-up roller 103 is arranged between the left wallboard 101 and the right wallboard 102. The take-up roller 103 is horizontally arranged transversely, and its left and right ends are respectively rotationally matched with the left wallboard 101 and the right wallboard 102 through a first bearing 107.

[0030] The driving mechanism is arranged in the left wallboard 101 and is in transmission cooperation with the left end of the take-up roller 103, and drives the take-up roller 103 to rotate around its axis. An output gear 110 is provided at the right end of the take-up roller 103. The driving mechanism includes a driving gear 104, a driving shaft 105 and an input gear 106. The input gear 106 is fixedly installed at the left end of the take-up roller 103, and both the input gear 106 and the output gear 110 rotate synchronously with the take-up roller 103.

[0031] The driving gear 104 is arranged in the left wallboard 101 through the driving shaft 105, and the driving gear 104 meshes with the input gear 106. Specifically, the axis of the driving shaft 105 is arranged relatively parallel to the axis of the coiling roller 103. The driving shaft 105 is rotationally matched with the left wallboard 101 through two second bearings 108, and its left end extends to the outside of the left wallboard 101 and can be connected to the transmission mechanism of the loom. The transmission mechanism drives the driving shaft 105 and the input gear 106 to rotate, and drives the coiling roller 103 to rotate through the input gear 106.

[0032] The damping mechanism includes a damping gear shaft 201, a connecting seat 204 and a damper. The damping gear shaft 201 is arranged in the right wallboard 102. The left end of the damping gear shaft 201 has a damping gear 203 with an integral structure therewith, and the damping gear 203 meshes with the output gear 110. The damping gear shaft 201 is arranged relatively parallel to the coiling roller 103 and is rotationally matched with the right wallboard 102 through two third bearings 202 arranged on the left and right. The damping gear 203 and the damping gear shaft 201 are of an integral structure, and the coiling roller 103 drives the damping gear shaft 201 to rotate through the output gear 110.

[0033] The damper is arranged on the right wallboard 102 through the connecting seat 204. The connecting seat 204 is fixedly installed on the right side wall of the right wallboard 102. The inner side of the connecting seat 204 is rotationally matched with the damping gear shaft 201 through the third bearing 202 on the right side. The right end of the damping gear shaft 201 passes through the damper and is provided with a compression nut 213.

[0034] The damper is a friction damper, which includes an elastic pressing assembly and an inner fixed friction disc 205, an intermediate rotating friction disc 208, an intermediate fixed friction disc 207, and an outer rotating friction disc 209 that are sequentially arranged at intervals from left to right along the damping gear shaft 201. The inner fixed friction disc 205 is located on the right side of the connecting seat 204 and is fixedly connected to the side wall of the right wallboard 102 through the connecting seat 204.

[0035] The intermediate fixed friction disc 207 is connected to the inner fixed friction disc 205. Both the intermediate rotating friction disc 208 and the outer rotating friction disc 209 are fixedly connected to the outer wall of the damping gear shaft 201 through flat keys, and the damping gear shaft 201 drives the intermediate rotating friction disc 208 and the outer rotating friction disc 209 to rotate synchronously.

[0036] Specifically, both the inner fixed friction disc 205 and the intermediate fixed friction disc 207 are annular structures, and the inner side walls of the inner fixed friction disc 205 and the intermediate fixed friction disc 207 are not in contact with the damping gear shaft 201. There are two support pin shafts 206 provided on the right side of the inner fixed friction disc 205. The intermediate fixed friction disc 207 is provided with positioning holes equal in number and corresponding in position to the support pin shafts 206. The left end of the support pin shaft 206 is fixedly connected to the intermediate fixed friction disc 207, and its right end passes through the right side wall of the intermediate fixed friction disc 207 through the corresponding positioning holes. The intermediate fixed friction disc 207 can move horizontally left and right along the support pin shafts 206.

[0037] The surface of the right side portion of the damping gear shaft 201 is provided with splines. The centers of the intermediate rotating friction disc 208 and the outer rotating friction disc 209 are provided with spline holes. The damping gear shaft 201 passes through the spline holes of the intermediate rotating friction disc 208 and the outer rotating friction disc 209 and drives the two to rotate synchronously therewith.

[0038] One friction plate 210 is respectively provided on the left and right sides of the intermediate rotating friction disc 208, and one same friction plate 210 is provided between the intermediate fixed friction disc 207 and the outer rotating friction disc 209.

[0039] The elastic pressing assembly is located on the right side of the outer rotating friction disc 209 and sleeved on the damping gear shaft 201. The pressing nut 213 locks the elastic pressing assembly on the outer rotating friction disc 209. The elastic pressing assembly includes a pressure spring 211 and a spring gland 212. The spring gland 212 is located on the right side of the pressure spring 211. The spring gland 212 makes the intermediate rotating friction disc 208, the intermediate fixed friction disc 207, the outer rotating friction disc 209 and the three friction plates 210 fit together through the pressure spring 211. Under the action of the pressure spring 211, the inner fixed friction disc 205 and the intermediate fixed friction disc 207 apply a frictional resistance opposite to their movement directions to the intermediate rotating friction disc 208 and the outer rotating friction disc 209 through the friction plates.

[0040] By tightening the pressing nut 213 to adjust the pressure to achieve the effect of adjusting the frictional resistance. When the coiling roller rotates, the damping gear shaft 201 is driven by the output gear 110 to drive the rotating friction disc to rotate. The fixed friction disc generates damping on the damping gear shaft 201 through the friction plate. The driving gear 104 meshes with the input gear 106 of the coiling roller 103, and the output gear 110 of the coiling roller meshes with the damping gear shaft 201, but the meshing contact directions of the two are respectively in the forward and reverse directions of the rotation of the coiling roller, solving the problem of the shaking of the coiling roller.

[0041] Example 2, in combination with Figures 1 to 4, A loom take-up device with damping function, its structure is generally the same as that of the loom take-up device with damping function in Embodiment 1 and the damping principle for the damping gear shaft 201. The difference is that the damper is a magnetic powder damper 310. The magnetic powder damper 310 is fixedly connected to the connecting seat 204 through a connecting disk 305 located on its left side. The right end of the damping gear shaft 201 passes through the inner shaft of the magnetic powder damper 310 and is fixedly connected to the inner shaft of the magnetic powder damper 310. Specifically, the damping gear shaft 201 penetrates into the connecting hole of the inner shaft of the magnetic powder damper 310 and is connected by a flat key. The outer pressing nut 213 connects the damping gear shaft 201 and the inner shaft of the magnetic powder damper 310 together. When the take-up roller 103 rotates, it drives the damping gear shaft 201 to rotate through the output gear 110 and drives the inner shaft of the magnetic powder damper 310 to rotate. By adjusting the current of the magnetic powder damper 310, the braking torque is further adjusted to achieve the required damping force.
