Embodiment 1

[0038] A recycling and crushing device for waste plastics, comprising an outer cylinder 1 and an inner cylinder 2, both arranged horizontally, the inner cylinder 2 fits inside the outer cylinder 1; the top of the outer cylinder 1 is provided with a feeding port, and the bottom is connected with a hopper 102; the inner cylinder 2 Corresponding to the feeding port, there is a feed port 201; the bottom of the inner cylinder 2 is also processed with a discharge port 202; one end of the outer cylinder 1 is installed with a No. 1 rotating motor 3, and the output shaft of the No. 1 rotating motor 3 extends horizontally and is connected with a rotating shaft 4. The rotating shaft 4 passes through the outer cylinder 1 and extends into the inner cylinder 2; the other end of the outer cylinder 1 is equipped with a No. 2 servo motor 7, and the output shaft of the No. The servo motor 7 drives the inner cylinder 2 to do swinging motion; the rotating shaft 4 is evenly installed with a moving ...

Embodiment 2

[0044] The difference from Embodiment 1 is that one end of the bottom of the outer cylinder 1 is provided with a support hydraulic rod 103, and the other end is provided with a fixed-height support foot 104, and the bottom of the support hydraulic rod 103 and support foot 104 is equipped with a base, a top and a discharge hopper 102 Hinged, by adjusting the expansion and contraction of the supporting hydraulic cylinder 103, the whole device is driven to shake around the supporting feet 104, assisting in crushing and grinding.

Embodiment 3

[0046] The difference from Embodiment 2 is that the feed inlet is provided with a feed hopper 101, and several inverted V-shaped partitions 1012 are installed at the bottom of the feed hopper 101, between the partitions 1012, the partition 1012 and the wall surface of the feed hopper 101 are composed of Feeding branch pipe; feed inlet 201 is arranged at the top of inner cylinder 2 at intervals, and the position of feed inlet 201 corresponds to the feeding branch pipe; the top of the outer cylinder 1 is also equipped with an adjustment cylinder 1011, which is arranged on the inlet On both sides of the hopper 101, the telescopic end of the adjustment cylinder 1011 is connected to the feed hopper 101 to drive the feed hopper 101 to move up and down.

[0047] The feeding hopper 101 is driven to move up and down by adjusting the cylinder 1011. When feeding, make the feeding branch pipe pass through the feeding port 201 to ensure that the material falls into the inner cylinder 2 comp...

Abstract

The invention relates to the technical field of plastic crushing and processing, and relates to a waste plastic recycling and crushing device and a crushing method. A double-layer type design is adopted, an inner cylinder serves as a primary crushing cavity, a movable knife is driven by a first rotating motor to interact with a static knife on the inner wall of the inner cylinder for cutting and crushing, meanwhile, particles fall between the inner cylinder and an outer cylinder, inner cylinder swings under the action of a second servo motor, the particle size is further reduced, and the qualified rate of the final finished product is improved; the inner cylinder performs swinging motion under the action of the second servo motor, and meanwhile, the falling of the particles is assisted, and the situation that the discharge hole is blocked is improved; one end of the bottom of the outer cylinder is provided with a supporting hydraulic rod, and the other end of the outer cylinder is provided with a supporting leg with a fixed height, the inner barrel and the outer barrel are driven to swing around the supporting leg by adjusting and supporting the supporting hydraulic rod, and auxiliary crushing, discharging and grinding are carried out; the feeding hopper moves up and down by the adjusting air cylinder, materials can be effectively prevented from entering the inner cylinder during feeding, and interference can not be caused when the device works.

Description

technical field [0001] The invention relates to the technical field of plastic crushing and processing, in particular to a recycling and crushing device and crushing method for waste plastics. Background technique [0002] Plastics are based on synthetic resins or natural resins, adding (or not adding) various plastic additives, reinforcing materials and fillers, and processed into solid materials or cross-linked solidified materials under certain temperature and pressure. There will be a lot of leftover materials in the plastic processing process of products. In addition, waste plastics such as waste plastics and leftover materials collected through recycling stations and other channels can be reused through reprocessing, which is in line with the concept of environmental protection and sustainable social development. Existing stirring and crushing devices have insufficient crushing and stirring, which cannot ensure the uniformity of stirring and crushing, and easily cause ...
