Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber processing equipment, and particularly relates to a weft wire breaking device for cut-off glass fiber. Background Art

[0002] After glass fiber is made into glass fiber filaments, it needs to be woven into glass fiber cloth by a warp knitting machine for subsequent use; after the warp knitting machine conducts textile production, there will be excess weft threads. In order to process these weft threads, people need to use a weft cutting device to cut them off to ensure the flatness of the edge of the glass fiber cloth.

[0003] For the weft cutting device of cut-off glass fiber, the excess glass fiber weft threads are cut off by the extrusion between the cutting knife and the sleeper. After the sleeper is used for a long time, many cutting marks will be cut out on it by the cutting knife, resulting in insufficient contact between the cutting knife and the sleeper. The edge cut of the glass fiber weft thread is relatively rough, affecting the quality of the finished product; sometimes, the weft thread even gets stuck in a larger cutting mark and cannot be cut off, affecting the cutting efficiency; at the same time, after the sleeper is used for a period of time, the part located below the cutting knife is consumed relatively seriously. At this time, if the sleeper is not replaced, a good cutting effect cannot be achieved. If the sleeper is directly replaced, the part that the cutting knife cannot contact is still relatively intact, which is a waste. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a weft wire breaking device for cut-off glass fiber, which fixes the sleeper on the cutting table. The sleeper can move left and right along the cutting table, aligning the unconsumed part of the sleeper with the cutting knife, so that the contact between the sleeper and the cutting knife is better and the utilization rate of the sleeper is higher.

[0005] The utility model includes a base, on which a tool rest is rotatably installed. A cutting knife is fixedly installed at the end of the tool rest, and a cutting table is arranged below the cutting knife; the cutting table includes a front wall and a rear wall arranged opposite to each other. A support plate is installed between the front wall and the rear wall, and a sleeper is fixedly installed on the support plate; sliding plates are slidably installed on the outer sides of the front wall and the rear wall, and open slots penetrating the front wall and the rear wall are arranged on the sides of the front wall and the rear wall; connecting plates are fixedly connected to the front and rear ends of the support plate, and the connecting plates pass through the open slots and are fixedly connected to the sliding plates.

[0006] Preferably, chutes are arranged on the upper parts of the front wall and the rear wall, and the chutes extend in the left-right direction; sliding blocks are fixedly connected to the upper parts of the sliding plates, and the sliding blocks slide in the chutes.

They only represent relative position relationships, not absolute position relationships.

[0023] like Figures 1 to 5 As shown together, a weft cutting device for cutting glass fiber comprises a base 1, a rotating shaft 5 is provided on the base 1, a tool holder 2 is rotatably mounted on the rotating shaft 5, a cutter 3 is fixedly mounted on the end of the tool holder 2, and a cutting table 4 is provided below the cutter 3; a spring 8 is connected to the tail of the tool holder 2, and the other end of the spring 8 is fixed on the base 1; a cam 7 is connected to the lower part of the tool holder 2, and the cam 7 is connected to the transmission shaft 6, and the transmission shaft 6 rotates under the drive of the motor, thereby driving the cam 7 to rotate, and during the rotation process, the cam 7 drives the tool holder 2 to intermittently swing up and down around the rotating shaft 5, thereby driving the cutter 3 to cut the weft located on the cutting table 4.

[0024] The cutting table 4 includes a front wall 401 and a rear wall 402 which are arranged opposite to each other. A support plate 403 is installed between the front wall 401 and the rear wall 402. A sleeper 404 is fixedly installed on the support plate 403. The sleeper 404 is used to receive the weft and can buffer the cutting force from the cutter 3 to prevent the cutter 3 from being damaged. Usually, the sleeper 404 is made of a softer material. A sliding plate 405 is slidably installed on the outer side of the front wall 401 and the rear wall 402. The side parts of the front wall 401 and the rear wall 402 are both provided with an opening groove 406 which penetrates the front wall 401 and the rear wall 402. The opening groove 406 is provided on the side of the front wall 401 and the rear wall 402. 06 extends in the left-right direction, and the front and rear ends of the support plate 403 are fixedly connected with connecting plates 407, which pass through the opening groove 406 and are fixedly connected to the sliding plate 405; when the sliding plate 405 slides on the front wall 401 and the rear wall 402, it drives the support plate 403 and the sleeper 404 to move left and right, thereby adjusting the position of the sleeper 404, and aligning the unconsumed part of the sleeper 404 with the cutter 3, so that the sleeper 404 is in better contact with the cutter 3, the weft thread breaking efficiency is higher, and each position of the sleeper 404 can be evenly and fully used to save costs.

[0025] Further, chutes 408 are provided at the upper parts of the front wall 401 and the rear wall 402. The chutes 408 extend in the left-right direction and are arranged in parallel with the opening slot 406. A slider 409 is fixedly connected to the upper part of the sliding plate 405. The slider 409 slides in the chute 408, thereby driving the pallet 403 and the sleeper 404 to move. The chutes 408 arranged in parallel on the front wall 401 and the rear wall 402 make the movement of the pallet 403 more stable.

[0026] Further, a V-shaped groove 410 is provided at the bottom of the opening slot 406. The V-shaped groove 410 extends along the length direction of the opening slot 406 and is arranged in parallel with the chute 408. A V-shaped block 411 is fixedly connected to the lower part of the connecting plate 407. The V-shaped block 411 slides in the V-shaped groove 410. The sliding plate 405 is in contact with both the front wall 401 and the rear wall 402 at the positions of the upper chute 408 and the V-shaped groove 410, making the load-bearing effect of the pallet 403 better.

[0027] Further, the four sides of the pallet 403 are turned up to form flanges 412. Clamping ridges 413 are provided at the tops of the flanges 412. The clamping ridges 413 are 3 / 4 circular, and the clamping ridges 413 around the four sides are inclined towards the center direction of the pallet 403 relatively, clamping the sleeper 404 on the pallet 403.

[0028] Further, a number of threaded holes 414 are arranged at intervals in the horizontal direction on the front wall 401 and the rear wall 402. Through holes 415 are provided at the corresponding positions of the sliding plate 405 to the threaded holes 414. Both the threaded holes 414 and the through holes 415 are arranged in two rows, and the two rows of threaded holes 414 and through holes 415 are respectively arranged on the upper and lower sides of the opening slot 406. After moving the sleeper 404 to a suitable position, fasteners are passed through the through holes 415 and the threaded holes 414 to fix the sliding plate 405.

[0029] Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples.
