Description

foam plastic grinder

technical field

The utility model relates to a device for crushing recycled foam plastics.

Background technique

Recycling and reusing foamed plastics can reduce environmental pollution and save production costs for enterprises. The recycled foamed plastics need to be crushed first. At present, most of the equipment for crushing foamed plastics in China can only be crushed. It is impossible to remove the sundries mixed in the foamed plastics, such as soil, iron nails, etc., which has an adverse effect on the reuse of the foamed plastics.

Utility model content

The purpose of the utility model is to solve the defect that the existing foam plastic pulverizer cannot remove impurities, and to provide a pulverizer that can crush foam plastic and remove dirt, iron nails and other sundries at the same time.

The technical scheme adopted by the utility model to realize the above-mentioned purpose is as follows:

A foamed plastic pulverizer, comprising a guide roller, a rough cutting roller and a material cutting roller, the guide roller is arranged at the material inlet of the foam plastic pulverizer, the rough cutting roller is located under the guide roller, and an assortment is arranged under the rough cutting roller. There is a blocking roller between the debris screen and the rough cutting roller, and an inclined baffle is arranged at the bottom of the debris screen, and the cutting roller is located at the outlet of the debris screen. A discharge screen is provided on the circumferential surface of the roller near the discharge port.

Further, two guide rollers are arranged horizontally side by side, one is driven by a motor, and the other is a follower.

Further, the roller surface of the retaining roller has evenly distributed rectangular teeth.

Beneficial effects: the foamed plastic pulverizer of the utility model adopts two-stage processing of rough cutting and fine cutting, and a screen for impurity removal treatment is added between rough cutting and fine cutting, and the sticky material after rough cutting is crushed by the impact of the retaining roller. The debris attached to the foam is removed, and the size of the foam particles is precisely controlled by the mesh of the discharge screen, which can realize fully enclosed operation and avoid flying dust.

Among them, 1-feed inlet, 2-guiding roller, 3-rough cutting roller, 4-retaining roller, 5-debris screen, 6-oblique baffle, 7-debris outlet, 8-support, 9- Upper baffle, 10-cutting roller, 11-discharge screen, 12-discharge port, (41, 42, 43)-rectangular teeth.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1, the foam plastic pulverizer includes a casing, a bracket, a guide roller, a rough cutting roller and a cutting roller. The casing is fixed by brackets.

The guide roller 2 is arranged at the material inlet 1 of the casing, and two guide rollers 2 are arranged horizontally side by side, one is controlled by a motor, and the other is used as a follower roller.

The rough cutting roller 3 is located below the guide roller 2, an upper baffle plate 9 is arranged obliquely above the rough cutting roller 3, and a sundry screen 5 is arranged below the rough cutting roll 3, and the sundry screen 5 maintains a certain inclination (30-40 degrees), at the same time, there is a retaining roller 4 between the rough cutting roller 3 and the debris screen 5, the retaining roller 4 is close to the discharge of the rough cutting roller 3, and the debris screen 5 The bottom is connected with an inclined baffle plate 6.

As shown in FIG. 2 , the blocking roller 4 has evenly distributed rectangular teeth ( 41 , 42 , 43 ) on the roller surface. The rectangular teeth of each layer are staggered from the adjacent rows of rectangular teeth.

Cutting material roller 10 is positioned at the discharging place of miscellaneous screen cloth 5, is provided with discharging screen cloth 11 on the peripheral surface of cutting material roller 10 being positioned at the discharge port 12 side of casing, an edge of discharging screen cloth 11 and The discharge edge of the debris screen 5 is welded, and the other edge of the discharge screen 11 is welded on the casing.

The rough cutting roller 3, the material retaining roller 4 and the material cutting roller 10 are respectively driven by a motor. The direction of rotation of the rough cutting roller 3 and the retaining roller 4 remains the same.

When working, the foamed plastic enters the pulverizer from the material inlet, and is squeezed to the rough cutting roller 3 under the action of the guide roller 2, and the foamed plastic after rough cutting by the rough cutting roller 3 falls on the debris screen 5, and is The blocking roller 4 provided at the outlet of the cutting roller 3 can increase the impact of the rough-cut foamed plastics, and shake off foreign matter such as earth adhering to the foamed plastics, and the foreign matter falls through the foreign matter screen 5 Slanted baffle plate 6 and discharge from the sundries outlet 7 of the casing, the foamed plastics that removes sundries enters the material cutting roller 10 along the slope of the sundries screen 5, and the foamed plastics is further finely cut by the material cutting roller 10, and then The discharge port 12 at the bottom of the casing collects qualified foamed plastic particles passing through the discharge screen 11 . The upper baffle plate 9 arranged obliquely above the rough cutting roller 3 can prevent the foamed plastic raw material from falling into the cutting roller without shearing, and can also prevent the chopped foamed plastics from being brought back.
