Pre-opening roller structure of waste fiber leftover pre-opener

Abstract

The invention relates to a pre-opening roller structure of a waste fiber leftover pre-opener, belonging to the field of non-woven fabric machines. The pre-opening roller structure comprises a pre-opening roller. The pre-opening roller consists of a pre-opening roller body, a first end disc, a second end disc, middle discs, hook cutter shaft seats and hook cutter shafts. A first opening roller body shaft head and a second opening roller body shaft head extend from the end surfaces of the two ends of the pre-opening roller body. The first end disc and the second end disc are fixedly arranged at the two ends of the pre-opening roller body. A group of middle discs are fixedly arranged at the middle part of the pre-opening roller body. A group of hook cutter shaft seats are equidistantly distributed around the circumferential direction of the pre-opening roller body. One ends of the hook cutter shaft seats are inserted into the first end disc, the other ends of the hook cutter shaft seats are inserted into the second end disc and the middle parts of the hook cutter shaft seats are inserted into the group of middle discs. Hook cutter shaft grooves are formed on the hook cutter shaft seats. A group of hook cutter shafts are distributed on the hook cutter shaft seats and are inserted into the hook cutter shaft grooves. One ends of the hook cutter shafts are fixedly connected with the first end disc and the other ends of the hook cutter shafts are fixedly connected with the second end disc. A group of hook cutters are sheathed at the middle parts of the hook cutter shafts. The pre-opening roller structure has the advantages of good opening effect, high efficiency, resource saving and reasonable and firm structure.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a pre-opening roller structure of a waste fiber leftover pre-opening machine, which is used for pre-opening special waste fiber leftovers to facilitate recycling and reuse of resources. Background technique [0002] The special waste fiber scraps mentioned above are mainly but not limited to the production of automotive interior parts such as automotive sound insulation felts and floor mats (the floor mats are usually laid on the car floor corresponding to the parts of the driver and co-driver) Cutting leftovers generated during the process. Because, as known to ordinary technicians in the automotive interior parts production industry, whether it is automotive sound insulation felt or floor mats and other similar products, its raw materials are generally made of low-melting thermoplastic fibers such as polypropylene fiber, low-melting thermoplastic fiber ...

AI Technical Summary

Problems solved by technology

In particular, when trying to open the aforementioned leftovers with this type of opener, it can only barely open about 20kg per hour, and because the quality of opening is not satisfactory, the fibers after opening can only be used for processing such as pipe coating Products or civilian products such as insoles, etc., the service life of this card clothing is extremely short and it needs to be replaced frequently

[0004] Based on the two factors that are not limited to the aforementioned low opening efficiency and poor opening quality (or effect), at present, manufacturers of automotive interior parts usually dispose of the aforementioned waste and leftovers, that is, either landfill or dispose of them. Incineration, resulting in the following disadvantages: First, it causes waste of resources, which is contrary to the conservation, energy-saving and circular economy spirit advocated by the whole society; second, landfill will pollute the soil and water systems, and incineration will have an impact on the atmospheric environment; The third is that the cost of automotive interior parts increases due to the inability to reuse
