Embodiment 1

[0034] Such as Figure 1-3 As shown, a crushing device for waste PP materials in this embodiment includes a main body 1, a feed hopper 2, a primary crushing device, a secondary crushing device, a tertiary crushing device, and a screening device.

[0035] The feed hopper 2 is fixed on the main body 1 and communicates with the inside of the main body 1;

[0036] The primary crushing device, which is located below the outlet of the feed hopper 2, includes a primary crushing chamber 3, a connecting rod 34, two crushing plates 35 and crushing teeth 37; the two crushing plates 35 are arranged side by side in the primary crushing chamber 3 On both sides, the connecting rod 34 passes through the outer wall of the primary crushing chamber 3 and is connected to the spring one 33. The other end of the spring one 33 is fixed on the movable plate 32, and the other side of the movable plate 32 opposite to the spring one 33 is fixed on the cam 31. Above, the cam 31 is driven by a second mot...

Embodiment 2

[0043] This embodiment applies the crushing method of the crushing device of the above embodiment, including the following steps:

[0044] First-level cutting, the material is fed into the first-level crushing chamber 3 through the feed hopper 2, and the second motor 30 is used to drive the cam 31 to periodically squeeze the movable plate 32. The crushing plate 35 connected by the connecting rod 34 and the telescopic rod 36 is in the The movable plate 32 is driven to collide periodically, and the crushing teeth 37 on the crushing plate 35 cut the waste for the first time;

[0045] Secondary crushing, the waste material cut for the first time is guided into the secondary crushing chamber 4 through two sloping plates 7, and the two sloping plates 7 are fixed on the outer wall of the secondary crushing chamber 4 to form a discharge channel; above the discharge channel, use The fixed frame 64 is equipped with the first motor 6, the rotating shaft 601 of the first motor 6 fixes the...

Abstract

The invention provides a crushing device and a crushing method for waste PP materials. The crushing device comprises a main body, a charging hopper, a first-stage crushing device, a second-stage crushing device, a third-stage crushing device and a screening device. The first-stage crushing device carries out cutting through sawtooth meshing, the second-stage crushing device carries out crushing through blades, the third-stage crushing device carries out crushing through gears, and the screening device is used for screening cut and crushed waste materials. According to the invention, before the waste materials enter the blades to be cut, a primary crushing device is arranged in a channel, the materials are cut into small parts for the first time, the crushing burden of the blades is relieved, and the service lives of the blades are prolonged. The materials are subjected to primary cutting, secondary blade crushing and third-time gear crushing through many times of crushing procedures, a high crushing degree is achieved, the materials reach a fine powder state after being crushed by the gears, and moreover, the swinging screening device is arranged after crushing, and the powder meeting the particle crushing requirement is screened out for reuse.

Description

technical field [0001] The invention belongs to the technical field of waste material recovery equipment, in particular to a crushing device and a crushing method for waste PP materials. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or polycondensation reactions. The composition and shape can be changed freely. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. composition. In the existing waste plastic crushing device, when the device is in operation, if too much waste plastic is put in, it is very easy to get stuck, and the existing crushing device is not very careful, and it needs secondary processing if necessary, which wastes Time, therefore, we propose a waste plastic shredding device to solve the above problems. Contents of the invention [0003] In view of the problems existing in the existing technical solutions, th...
