Description

A kind of opening machine for felt pad production

Technical Field

The utility model relates to an opener for producing felt pads, belonging to the technical field of openers.

Background Art

The main function of the opener is to loosen fibers, cotton, textiles and other materials. It loosens large pieces of tangled fibers into small pieces or bundles by tearing them apart. At the same time, the loosening process is accompanied by mixing and removing impurities. The opener is generally composed of a pair of feeding rollers or feeding rollers and a loosening cylinder. The opening cylinder is equipped with corner nails or combing needles or needle cloths or porcupine beaters. In order to open more thoroughly, some are also equipped with working rollers and stripping rollers on the cylinder. Different structures make their opening effect, mixing effect and impurity removal effect have obvious differences. Therefore, different forms of openers should be used on production lines with different requirements.

The existing patent number is CN201921018903.7, which discloses a short-hair opener, including an opener body, a feeding belt and a dust removal structure, wherein a discharge port is arranged at the rear end of the opener body, and a dust removal structure is arranged at the bottom of the discharge port, a dust removal chamber and a dust collecting chamber are arranged inside the dust removal structure, a discharge belt is arranged in the dust removal chamber through a transmission roller, and a first through hole is evenly distributed on the discharge belt, a dust suction pipe is arranged inside the discharge belt, and the dust suction pipe is evenly distributed at the discharge belt with a second through hole, a dust collecting pipe is installed inside the dust collecting chamber, an axial flow fan is installed at the rear end of the dust collecting pipe through a driving motor, a dust collecting bag is sleeved at the rear end of the dust collecting pipe, and both ends of the dust suction pipe extend downward into the dust collecting chamber, and are fixedly connected to both sides of the dust collecting pipe. The utility model can effectively collect dust in the material after opening by arranging a dust removal structure at the rear end of the traditional opener body, reduce the time for subsequent cleaning, and save costs.

In this public patent, the fan blades for dust extraction are fixedly installed inside the conveyor body, which makes it inconvenient to clean the surface of the blades regularly. During the dust extraction process of the fan, some dust will be continuously adsorbed on the surface of the blades. If the dust accumulates too much, the rotation speed of the fan blades will be reduced and the life of the fan will be reduced. The reduction in the fan rotation speed will directly reduce the efficiency of dust extraction.

Please refer to Figures 1-3, a felt pad production opener includes a housing 1 and a plurality of mounting housings 2. The housing 1 is provided with a plurality of connecting holes 3 on the front side. The number of the connecting holes 3 is the same as the number of the connecting pipes 9, which are three, and are used to connect the connecting pipes 9 with the dust chamber 15 inside the housing 1. The housing 1 is fixedly connected with a plurality of externally threaded fixing tubes 4 on the front side. The number of the externally threaded fixing tubes 4 is three, and the inner surface of each externally threaded fixing tube 4 is provided with four card slots for limiting the mounting housing 2. Four card plates are fixedly installed on the mounting housing 2. When installing, the card plates are inserted into the corresponding card slots to prevent the mounting housing 2 and the internally threaded fixing tubes 4 from being connected. The mounting tube 6 rotates together, and after the position of the mounting shell 2 is fixed, the mounting shell 2 and the connecting tube 9 can be fixedly installed by rotating the internally threaded mounting tube 6 through the adjusting handle 7 until it rotates to the outer surface of the externally threaded fixing tube 4 to prevent the mounting shell 2 and the internally threaded mounting tube 6 from rotating together. The outer surfaces of several mounting shells 2 are fixedly connected with the limiting ring 5, and the limiting ring 5 limits the moving range of the internally threaded mounting tube 6. The outer surfaces of several mounting shells 2 are all threadedly connected with the internally threaded mounting tube 6.
