Waste fiber leftover pre-opener

Abstract

The invention relates to a waste fiber leftover pre-opener, belonging to the field of non-woven fabric machines. The waste fiber leftover pre-opener comprises a pre-opening roller rack, a waste fiber leftover conveying mechanism, a pre-opening roller, a pressing mechanism, a feeding mechanism, a pre-opening roller driving mechanism, a power transmission mechanism and a fiber leading-out mechanism, wherein a first wallboard is fixedly arranged above one side of the pre-opening roller rack and a second wallboard is fixedly arranged above the other side of the pre-opening roller rack; the waste fiber leftover conveying mechanism is connected with one end of the pre-opening roller rack; the pre-opening roller is supported between the first wallboard and the second wallboard; the pressing mechanism is arranged on the waste fiber leftover conveying mechanism; the feeding mechanism is arranged on the pre-opening roller rack and is arranged between the pre-opening roller and the pressing mechanism; the pre-opening roller driving mechanism is arranged on the pre-opening roller rack and is connected with the pre-opening roller; the power transmission mechanism is arranged on the pre-opening roller rack and is connected with the waste fiber leftover conveying mechanism, the pressing mechanism and the feeding mechanism; and the fiber leading-out mechanism is fixedly arranged on the pre-opening roller rack. The waste fiber leftover pre-opener has the advantages that the opening effect is good, the opening efficiency is ideal, the requirement on reuse of waste fibers can be satisfied, the resources are saved, the environment is protected, the circular economy is reflected and the manufacturing cost of automobile interior ornaments is reduced.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a waste fiber leftover pre-opening machine, which is used for pre-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) 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 Mixed fibers mixed with natural...

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
