Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pellet processing technology, and in particular to a quiet and noise-reducing plastic pellet recycling and processing equipment. Background Technology
[0002] After being processed into pellets, waste plastics still have good reuse value and can meet the technical requirements of blown film, wire drawing, pipe drawing, injection molding, and extrusion profiles. They are widely used in the production of plastic products. In daily life, recycled pellets can be used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery, and other household items and plastic products. In industry, they can be used to manufacture various machine parts, vehicles, cables, and clothing. In agriculture, they can be used to make agricultural films, water pipes, agricultural machinery, fertilizer packaging bags, and cement packaging bags. In building materials, they can be used to manufacture various building components, construction tools, doors, windows, and pipes. In recent years, my country's industry has developed rapidly, and the market has been booming. There are already dozens of large plastic markets, and the price of waste plastic pellets has been rising again and again, with supply falling short of demand.
[0003] Existing technologies have the following problems:
[0004] In existing technologies, plastic recycling equipment mainly focuses on improving crushing efficiency and preventing screen clogging. For example, Chinese patent application CN202022426063.7 discloses a plastic pellet processing equipment that avoids clogging by using a vibrating screening plate. However, such equipment still has significant defects in actual operation, especially the noise pollution problem that urgently needs to be solved. During the plastic pellet recycling process, the high-speed mechanical movement of the equipment, such as the crusher, motor drive system, and material collision, will generate high-intensity noise, often exceeding 85 dB. Long-term exposure to such an environment can easily lead to hearing damage and psychological stress for operators. In addition, due to structural design defects, the vibration transmission path of traditional equipment is not effectively blocked, further aggravating noise diffusion. For example, rigidly connected transmission components are prone to resonance, and repeated collisions between materials and blades in the crushing chamber will also generate high-frequency noise. Although existing technologies have partially alleviated vibration through basic measures such as shock-absorbing pads, the sound insulation and noise reduction effects are limited. On the other hand, existing equipment has the problem of insufficient crushing uniformity, and the blades will wear out after repeated use, making blade replacement cumbersome and laborious.
[0005] To address these shortcomings, we have proposed a quiet, noise-reducing plastic granule recycling and processing equipment. Utility Model Content
[0006] The purpose of this invention is to provide a quiet and noise-reducing plastic granule recycling and processing equipment to overcome the shortcomings of existing technologies.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a silent and noise-reducing plastic granule recycling and processing equipment, comprising a base and a crushing chamber. The crushing chamber is connected to the base, and an inlet and a outlet are fixedly installed on the top and bottom surfaces of the crushing chamber, respectively. Housings are fixedly connected to both sides of the crushing chamber, and drive motors are fixedly installed on the bottom surfaces of both housings. The output ends of the two drive motors extend into the two housings and are fitted with spiral lifting blades. A discharge pipe and an inlet are fixedly installed on the upper and lower ends of the side surface of the two housings near the crushing chamber, respectively. The material pipe, the discharge pipe and the feed pipe are respectively connected to the feed port and the discharge port. The outer walls of the two shells are welded with a support frame, and the support frame is connected to the base through a shock absorber. The inner wall of the base is provided with a limit groove. The support frame is slidably connected to the limit groove. A crushing motor is fixedly installed on one side surface of the crushing chamber, and the output end of the crushing motor extends into the crushing chamber and is installed with a rotating block. The surface of the rotating block is provided with a threaded groove in an annular shape, and a threaded rod is threadedly connected in the threaded groove. A bracket is installed at one end of the threaded rod, and a cutter is installed on the bracket.
[0008] Preferably, the outer wall of the crushing chamber is detachably fitted with a maintenance plate.
[0009] Preferably, a scraper is installed at the other end of the support, and the surface of the scraper is in contact with the inner wall of the crushing chamber.
[0010] Preferably, a control switch is fixedly installed on the outer wall of the crushing chamber, and the control switch is electrically connected to the crushing motor and the drive motor through wires.
[0011] Preferably, both the feed pipe and the discharge pipe are inclined.
[0012] Preferably, the end of the feed pipe closest to the housing is lower than the other end.
[0013] Preferably, the end of the discharge pipe closest to the shell is higher than the other end.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, by setting spiral lifting blades, the plastic particles after preliminary crushing enter the housing through the feed pipe and are lifted upward by the spiral lifting blades. Finally, they return to the crushing chamber through the discharge pipe for secondary crushing. The plastic particles are crushed more evenly, avoiding the problem of uneven crushing in some areas. At the same time, the detachable blades are convenient for disassembly, maintenance and replacement. The design is ingenious and worth promoting.

A bracket 7 is installed at one end of the threaded rod 8, and a cutter 9 is installed on the bracket 7.
[0027] In use, plastic granules are fed into the crushing chamber 2 through the feed inlet 3, and then the crushing motor 4 is started to drive the blades 9 to rotate, thereby crushing the plastic granules. With the setting of spiral lifting blades 15, the initially crushed plastic granules enter the housing 13 through the feed pipe 12 and are lifted upward by the action of the spiral lifting blades 15.
