[0001] The utility model patent relates to the technical field of rapier looms, in particular to a coiling and collecting device for a rapier loom. Background Art

[0002] A rapier loom is an efficient weaving machine, mainly used for producing high-quality fabrics, especially excellent in producing fancy fabrics with multi-color weft insertion. A rapier loom mainly consists of a frame, a main drive system, a shedding mechanism, a weft insertion mechanism, a beating-up mechanism, a warp feeding mechanism, a coiling mechanism and other parts.

[0003] There is a coiling device mentioned in CN214004953U in the prior art. Although it solves the problem of manual handling of the coiling roller, the applicable scenarios of this technology are limited. When using the clamping jaws, a large clamping force is required, and at the same time, the coiled fabric will also shift; on the other hand, when cutting the fabric, the fabric often loosens and shifts because it is not pressed tightly. Therefore, there is an urgent need for a coiling and collecting device for a rapier loom to solve the above problems. Summary of the Invention

The pushing mechanism is fixedly installed on the base, and the coiling mechanism is fixedly installed on the support frame. The coiling mechanism is arranged in sequence as a pressing roller, a guiding roller and a fabric coiling roller. A pressure roller is hinged at the roller shaft of the guiding roller. One end of the fabric coiling roller is fixedly installed with a driven wheel. An installation groove is opened on the roller circumference of the fabric coiling roller. An installation cylinder is sleeved on the fabric coiling roller. Positioning plates are inserted at both ends of the installation cylinder, and a pushing mechanism is arranged outside the positioning plates.

[0008] As a preferred technical solution, the pressing rollers are a pair of upper and lower ones. Adjusting gears are fixedly installed at both ends of the shafts of the pressing rollers, and a rack is meshed on one side of the adjusting gears.

[0009] As a preferred technical solution, the support frame is provided with an adjusting groove, the pressing roller is inserted into the adjusting groove, and the rack is fixedly installed on one side of the adjusting groove.

[0010] As a preferred technical solution, the pressure roller naturally drops due to its own gravity, and a groove is opened in the moving direction at the roller shaft of the pressure roller.

[0011] As a preferred technical solution, the pushing mechanism includes a pushing fork, which is fixedly installed on the carriage nut. The carriage nut is threadedly installed on the lead screw, and the lead screw is fixedly installed on the support frame. One end of the lead screw is fixedly installed with a first rotating motor.

Detailed implementation manners

[0023] The coiling and collecting device of a rapier loom according to the present utility model will be further described in conjunction with the accompanying drawings.

[0024] As shown in the Figure 1 accompanying drawings, a coiling and collecting device of a rapier loom includes a base 1, a support frame 2, a pushing mechanism 4 and a winding mechanism 3. The pushing mechanism 4 is fixedly installed on the base 1, and the winding mechanism 3 is fixedly installed on the support frame 2. The winding mechanism 3 is arranged in sequence as a pressing roller 31, a guide roller 32 and a cloth winding roller 33. A pressure roller 34 is hinged at the roller shaft of the guide roller 32. One end of the cloth winding roller 33 is fixedly installed with a driven wheel 333. Mounting slots 332 are provided on the circumferential surface of the cloth winding roller 33. A mounting cylinder 331 is sleeved on the cloth winding roller 33. Positioning plates 334 are inserted at both ends of the mounting cylinder 331. The pushing mechanism 4 is arranged outside the positioning plates 334.

[0025] As shown in the Figure 2 accompanying drawings, further, the pressing rollers 31 are a pair of upper and lower ones. Adjusting gears 311 are fixedly installed at both ends of the shaft of the pressing roller 31. A rack 22 is engaged with one side of the adjusting gear 311.

[0026] As shown in the Figure 3 accompanying drawings, further, the support frame 2 is provided with an adjustment groove 21. The pressing roller 31 is inserted into the adjustment groove 21. The rack 22 is fixedly installed on one side of the adjustment groove 21.

[0027] Further, the pressure roller 34 naturally sags under its own gravity. A groove is provided in the moving direction at the roller shaft of the pressure roller 34.

[0028] As shown in the Figure 4 accompanying drawings, further, the pushing mechanism 4 includes a pushing fork 41. The pushing fork 41 is fixedly installed on a slide nut 42. The slide nut 42 is threadedly installed on a lead screw 43. The lead screw 43 is fixedly installed on the support frame 2. A first rotating motor 5 is fixedly installed at one end of the lead screw 43.

[0029] Further, a second rotating motor 44 is installed on the base 1. The output end of the second rotating motor 44 is fixedly installed with a driving wheel 6. The driving wheel 6 and the driven wheel 333 are driven by a belt 7.

[0030] The working principle of the present utility model is as follows: The fabric passes through the pressing roller 31, the guiding roller 32, and the pressure roller after the guiding roller 32, and finally is placed on the cloth winding roller 33. First, the gap between the pressing rollers 31 is adjusted through the rack 22 and the adjusting gear 311 to adapt to fabrics of different thicknesses. The first rotating motor 5 is started, the driving wheel 6 rotates, and is transmitted to the driven wheel 333 through the belt 7, driving the cloth winding roller 33 to rotate and wind the cloth. The positioning plate 334 provided beside the mounting cylinder 331 can effectively center the wound fabric. After the fabric is wound to the required length, the first rotating motor 5 is stopped, the pressure roller 34 provides downward pressure to press the fabric, and then the fabric is cut. The pressure roller 34 can press down and tighten the fabric to make the cutting more accurate and precise, prevent the fabric from shifting, reduce the inclination rate of fabric cutting, and reduce the generation of waste. After cutting, the push fork 41 on the side of the positioning plate 334 is driven by the second rotating motor 44 to rotate the lead screw 43, which will push the positioning plate 334 and push the mounting cylinder 331 outwards for replacement, and then it falls into the fabric storage box or the transfer box.
