Description

Rapier loom with slitter edge collecting function Technical Field The invention relates to the technical field of rapier looms, in particular to a rapier loom with a slitter edge collecting function. Background In the weaving process of the rapier loom, after weft yarns are introduced into the warp yarn layer, redundant slitter edges are formed on two sides of the cloth. In order to ensure the normal operation of the loom, the stable quality of the fabric and the clean production environment, the waste edges of the part need to be treated, so that the waste edges are prevented from scattering and winding equipment parts, causing the failure of the loom or causing defects on the cloth cover. In the prior art, the slitter edge is processed by combining cutting and negative pressure suction, and slitter edges at the edges of the cloth are cut through slitter edge cutting components, so that the slitter edges form uniform short sections, and long slitter edge winding equipment is avoided. The cut slitter edges are transferred by means of a negative pressure suction system, the system takes a fan as a power source, air flow is formed by generating negative pressure, the air flow carries the slitter edges to be conveyed along a suction pipeline, and finally the slitter edges are transferred into a collecting box to be collected. The stable operation of the negative pressure suction system depends on a complete air flow circulation closed loop, and the working logic of the negative pressure suction system is that a fan generates negative pressure, air flow carries waste edges into a collecting box, separation of air and the waste edges is needed to be realized, the waste edges are reserved in the collecting box while the air is smoothly discharged, so that the negative pressure in a pipeline is maintained stable, and the continuous and effective suction function is ensured. However, the existing slitter edge collecting device has a plurality of problems to be solved in practical application, the problems are influenced by the characteristic that the slitter edge is light in self-texture, the slitter edge is difficult to stably settle after entering the collecting box, continuous suspension and repeated flying phenomena are easily formed in the box, uniform accumulation cannot be realized, a series of linkage problems are caused, part of suspended slitter edge can be rolled back to a suction pipeline by disordered air flow in the box to form slitter edge reflux, the reflowed slitter edge can be accumulated on the inner wall of the pipeline in a gradual attaching mode, the through-flow section of the pipeline is reduced, the air flow resistance is increased, the suction efficiency is reduced, the pipeline is blocked gradually, even the light slitter edge can reflow and overflow and scatter to the periphery of a loom and a production workshop, the production environment is polluted, the cleaning workload of the workshop is increased, the surface of core moving parts such as a rapier, a beating reed, a warp feeding roller and a winding roller of the loom is also caused, the parts are blocked and worn, the parts are blocked and broken due to long-term accumulation, the unplanned shutdown is caused, the equipment maintenance cost is increased, and the production rhythm is also disturbed. Meanwhile, the scattered slitter edges are easy to hook and wind with the normally woven fabric, so that warp yarns and weft yarns are broken, cloth defects are generated, the qualification rate of the fabric is reduced, and the production loss is increased; More importantly, when gas-solid separation is carried out, suspended and flying slitter edges are continuously carried by air flow and are attached to the surface of a screen plate of the filtering device, so that a compact yarn film is gradually formed, and the partial or even whole filter screen holes are blocked. After the filter screen is blocked, the ventilation resistance can be greatly increased, so that air cannot be smoothly discharged, the air pressure balance in the collecting box is broken, the pressure in the collecting box is further increased, the negative pressure in the pipeline is suddenly reduced, the suction function is finally invalid, and the normal transfer and collection of waste edges cannot be completed. After the suction function fails, the cut slitter edges can be continuously piled up in a cutting area, blades and rotating shafts of the cutting part are wound, the linkage causes the cutting resistance to be increased and the precision to be reduced, and the problems of continuous slitter edge cutting and different lengths occur, so that a vicious circle of poor cutting, slitter edge piling, suction failure and worse cutting is formed. In addition, the filter screen is blocked by the yarn membrane for a long time, the negative pressure suddenly drops to cause abnormal rise of the fan load, the fan motor is easy to overheat and the impeller is easy to def
