Description

Waste plastic crushing device

Technical Field

The utility model belongs to plastics recycling equipment, concretely relates to waste plastics breaker.

Background

The plastic is a material commonly used in industry and life, and brings great convenience to people. However, the environment is also damaged correspondingly. Therefore, recycling of plastics and reduction of environmental pollution are problems which need to be solved urgently at present. After the plastic is recovered, the plastic is crushed, re-melted and then cooled and formed to be made into plastic particles which become new plastic raw materials. The existing waste plastic crushing device cannot separate crushed plastic fragments from plastic which does not reach the crushing standard in time, so that the crushing efficiency is influenced; and when the crushing mechanism runs at a high speed for crushing, the plastic sheets are attached to the inner wall of the crushing device under the action of centrifugal force, so that incomplete crushing is caused, and the crushing requirement cannot be met.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a waste plastics breaker, be equipped with the broken section of thick bamboo of support including the bottom, be equipped with a broken sieve section of thick bamboo in the broken section of thick bamboo, the top of a broken section of thick bamboo is equipped with crushing motor, crushing motor's output and broken hub connection, broken hub connection extends to in the broken sieve section of thick bamboo, be equipped with a plurality of blades on the broken hub connection, the both sides and the broken section of thick bamboo inner wall of broken sieve section of thick bamboo pass through spring coupling, broken section of thick bamboo inner wall is equipped with the support frame that is used for supporting motor, suit cam in the pivot of motor, the cam rotates and forms the extrusion force to a broken sieve section of thick bamboo and makes the vibration about.

In the preferred scheme, the upper end both sides of a broken sieve section of thick bamboo are equipped with first backup pad, and the relative first backup pad of broken section of thick bamboo inner wall is equipped with the second backup pad, is equipped with the spout in the second backup pad, first backup pad bottom be equipped with spout complex slider.

In a preferred scheme, the blades are arc-shaped blades, and the blades are arranged on two sides of the crushing shaft in pairs and have opposite blade directions.

In the preferred scheme, the feed inlet is provided with two crushing rollers in parallel.

In a preferable scheme, a belt conveyor is arranged below the discharge opening.

The utility model provides a waste plastic crushing device, which forms reciprocating extrusion force to a crushing screen drum through a motor and a cam, and enables the crushing screen drum to vibrate in a reciprocating manner from left to right under the combined action of a spring, thereby being beneficial to enabling the crushed plastic sheets in the crushing screen drum to fall into the crushing drum from the crushing screen drum, realizing the separation of the crushed plastic sheets from other plastics, reducing the load of a blade and improving the crushing efficiency; because the attached plastic sheet of a broken sieve section of thick bamboo inner wall of centrifugal force shakes in falling to a broken sieve section of thick bamboo, prevents to block up the mesh of a broken sieve section of thick bamboo, simultaneously, prevents that attached plastics of a broken sieve section of thick bamboo inner wall can not thoroughly broken, improves crushing effect.

Drawings

The invention will be further explained with reference to the following figures and examples:

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a schematic structural view of the blade of the present invention.

In the figure: the crushing device comprises a crushing cylinder 1, a support 2, a crushing screen cylinder 3, a crushing motor 4, a crushing shaft 5, a blade 6, a spring 7, a motor 8, a supporting frame 9, a cam 10, a valve 11, a first supporting plate 12, a second supporting plate 13, a sliding block 14, a crushing roller 15, a belt conveyor 16, a feeding opening 101, a discharging opening 102 and a sliding groove 1301.

Detailed Description

as shown in fig. 1 ~ 2, a waste plastic crushing device, be equipped with broken sieve section of thick bamboo 1 of support 2 including the bottom, be equipped with broken sieve section of thick bamboo 3 in broken section of thick bamboo 1, broken sieve section of thick bamboo 3 upper end opening, lateral wall and bottom are equipped with the mesh, the plastics piece that supplies broken completion leaks down, the top of broken section of thick bamboo 1 is equipped with crushing motor 4, the output and the broken axle 5 of crushing motor 4 are connected, broken axle 5 extends to in broken sieve section of thick bamboo 3, be equipped with a plurality of blades 6 on the broken axle 5, the both sides and the broken section of thick bamboo 1 inner wall of broken sieve section of thick bamboo 3 pass through spring 7 and are connected, broken section of thick bamboo 1 inner wall is equipped with the support frame 9 that is used for supporting motor 8, suit cam 10 in the pivot of motor 8, cam 10 rotates and forms the extrusion force to broken sieve section of thick bamboo 3 and makes broken sieve section of.

Form reciprocating extrusion force to a crushing sieve section of thick bamboo 3 through motor 8 and the cam 10 that sets up, under spring 7's combined action, make a crushing sieve section of thick bamboo 3 control reciprocating vibration, be favorable to the plastic sheet that has broken completion in a crushing sieve section of thick bamboo 3 to fall into crushing sieve section of thick bamboo 1 from a crushing sieve section of thick bamboo 3 on the one hand, realize accomplishing the separation of broken plastic sheet and other plastics, reduce the load of blade 6, on the other hand is because the attached plastic sheet that shakes of a crushing sieve section of thick bamboo 3 inner wall of centrifugal force falls to a crushing sieve section of thick bamboo 3 in, prevent to block up the mesh of a crushing sieve section of thick bamboo 3, and simultaneously, prevent that attached plastics of a crushing sieve section of thick bamboo.

The upper end both sides of broken sieve section of thick bamboo 3 are equipped with first backup pad 12, and 1 inner wall of broken section of thick bamboo is equipped with second backup pad 13 relative first backup pad 12, is equipped with spout 1301 in the second backup pad 13, and 12 bottoms of first backup pad are equipped with and spout 1301 complex slider 14. Through the cooperation of spout 1301 and slider 14, play the supporting role to crushing sieve section of thick bamboo 3 on the one hand, improve the stability of reciprocating vibration about, can not influence simultaneously that crushing sieve section of thick bamboo 3 moves about.

The feed inlet 101 is provided with two crushing rollers 15 in parallel. Waste plastics falling from the charging opening 101 are primarily crushed under the rolling action of the two crushing rollers 15, the working pressure of the blade 6 is reduced, and the crushing efficiency is improved.

As shown in fig. 2, the blades 6 are arc-shaped blades, and the blades 6 are arranged on two sides of the crushing shaft 5 in pairs and have opposite blade directions. The blade 6 is arc-shaped, so that plastics in all directions in the crushing screen drum 3 can be cut off, and the crushing dead angle is reduced.
