Waste fiber leftover material opening machine

Abstract

The invention relates to a waste fiber leftover material opening machine. The waste fiber leftover material opening machine comprises a frame, wherein the frame comprises a left wall plate, a right wall plate and a connecting bottom beam; an opening cylinder, the opening cylinder is fixed between the left and the right wall plates, the rear upper side of left end of the opening cylinder is provided with an opening cylinder waste fiber feeding inlet, the rear lower side of right end of the opening cylinder is provided with an opening fiber leading-out outlet, a waste fiber fixing opening hook base is arranged on the cavity wall of the opening cylinder body cavity, the waste fiber fixing opening hook base is provided with a waste fiber fixing opening hook; an opening roller is positioned inthe body cavity of the opening cylinder, the left end of the opening roller shaft is supported on the left wall plate, the right end is supported on the right wall plate, a waste fiber movement opening hook base is arranged on the outer wall of the opening roller, and a waste fiber movement opening hook is arranged on the waste fiber movement opening hook base; an power transmission mechanism is arranged on the front side of the left wall plate and is connected with the left end of the opening roller shaft; and an opening fiber leading-out mechanism is connected with the opening fiber lead-outoutlet. The waste fiber leftover material opening machine has the advantages that the opening effect is good, the efficiency is high, and the recycling requirement of the waste fiber can be met; small volume and less space occupation; and the opening quality of the waste fiber is ensured.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a waste fiber leftover opening machine, which is used for opening special waste fiber leftovers to facilitate the recovery 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) Redundant leftovers that are cut 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 Mixed fibers mixed with natural fi...

Problems solved by technology

In addition, due to the addition of low-melting-point fibers during the preparation process, the low-melting-point fibers tend to vitrify and solidify to form a certain hardness during the hot-pressing forming stage, so as to reflect the tear resistance during use. Due to the hardness It has both strength and strength, so it is difficult to use known openers such as CN100368612C (opener), CN102586956A (fiber opener), CN102586955A (opener with impurity removal function) and CN1710165A (opener) or similar openers. Effective loosening by loosening machine

Because, since this type of opening machine is designed for the opening of normal non-woven fibers, the phenomenon of "acclimatization" will soon be exposed when opening the waste scraps with both hardness and strength.

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.

[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
