Description

Plastic granulator

Technical Field

The utility model relates to a pelleter field especially relates to a plastic granulator.

Background

In the plastic extrusion granulation production process, the plastic melt is melted and mixed by an extruder and then extruded into a strip shape by an extruder die head, and the strip-shaped melt is solidified and shaped after being cooled by air or water so as to be conveniently cut into granules for packaging and storage. Because the extrusion speed of the plastic is high, the cooling time of the strip plastic, particularly the plastic with low processing temperature and high viscosity, after being extruded from the machine head is short, most of the heat of the strip plastic is transferred to the moving blade of the granulator, the fixed blade of the granulator, the rubber roll and the granulator in the granulating process. Along with the increase of the temperature of equipment, the cooling effect of strip plastics is worse and worse, and plastic particles are easy to adhere to a cutter and even block the cutter.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a plastic granulator.

The utility model discloses a realize through following technical scheme:

the utility model provides a plastic granulator, includes the pelleter body, it is connected with driven compression roller to rotate on the inner wall of pelleter body, pelleter body inner wall is close to driven compression roller department and rotates and is connected with the initiative pinion cutter, and the height of initiative pinion cutter is higher than driven compression roller, pelleter body top is fixed with the cooling duct of intercommunication, and the cooling duct is between driven compression roller and the initiative pinion cutter towards downwards, be fixed with the cleaning brush on the inner wall of pelleter body, cleaning brush and the contact of initiative pinion cutter, the feed inlet has been seted up to the opposite side of pelleter body, the discharge gate has been seted up to the bottom of pelleter body.

Furthermore, an inclined baffle is fixed at the bottom of the granulator body.

Further, the driven press roller is made of rubber.

Further, the bristles on the cleaning brush are made of high-temperature-resistant and wear-resistant polyamide fibers.

The utility model has the advantages that:

the utility model discloses a novel plastic granulator, which consists of a cooling air duct, a feed inlet, a driving gear cutter, a driven compression roller, a baffle and a cleaning brush; the cooling air in the cooling air duct can effectively cool the plastic particles, the driving gear cutter and the driven compression roller, and is beneficial to cleaning the residual plastic particles on the blade; and the plastic particles adhered to the driving gear cutter can be cleaned in time more effectively through the brush, the granulating effect is improved, and the plastic particles are ensured to be uniform in shape.

Drawings

Fig. 1 is a schematic front view of the present invention;

in the figure: 1. a granulator body; 2. a driven press roll; 3. a driving gear cutter; 4. a cooling air duct; 5. a cleaning brush; 6. a feed inlet; 7. a baffle plate; 8. and (4) a discharge port.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a pelleter body 1, it is connected with driven compression roller 2 to rotate on pelleter body 1's the inner wall, 1 inner wall of pelleter body is close to driven compression roller 2 department and rotates and be connected with drive gear sword 3, and drive gear sword 3 highly is higher than driven compression roller 2, 1 top of pelleter body is fixed with the cooling duct 4 of intercommunication, and cooling duct 4 is down between driven compression roller 2 and the drive gear sword 3 towards, be fixed with cleaning brush 5 on pelleter body 1's the inner wall, cleaning brush 5 and the contact of drive gear sword 3, feed inlet 6 has been seted up to pelleter body 1's opposite side, discharge gate 8 has been seted up to pelleter body 1's bottom.

When using like this, banding plastics fuse-element enters into between driven compression roller 2 and the initiative pinion cutter 3 through feed inlet 6, initiative pinion cutter 3 is connected with the motor and drives it and rotate, drive the fuse-element through the rotation of initiative pinion cutter 3 and move forward like this, and provide holding power through driven compression roller 2 and come to cut up banding fuse-element, the unloading can be accomplished through discharge gate 8 downwards to the plastic granules of cutting up, and when the during operation, cooling duct 4 can be connected with outside cooling blower and come to provide the cooling air to inside, can cool off driven compression roller 2 and initiative pinion cutter 3, prevent that plastic granules from gluing on the cutter, and can more effectively clear up the plastic granules who glues on initiative pinion cutter 3 in time down through the brush, improve and cut a grain effect, guarantee that the plastic granules shape is even unanimous.

An inclined baffle 7 is fixed at the bottom of the granulator body 1. The baffle 7 prevents plastic particles from scattering around the inside of the pelletizer.

The driven press roll 2 is made of rubber. The bristles of the cleaning brush 5 are made of high temperature resistant and wear resistant polyamide fibers. The rubber has good friction force, so that the strip-shaped melt is prevented from slipping, and the bristles cannot be worn by the rotating driving gear cutter 3.

The utility model has the advantages that:

the novel plastic granulator of the utility model comprises a cooling air duct 4, a feed inlet 6, a driving gear cutter 3, a driven compression roller 2, a baffle 7 and a cleaning brush 5; the cooling air in the cooling air duct 4 can effectively cool the plastic particles, the driving gear cutter 3 and the driven press roll 2, and is beneficial to cleaning the plastic particles remained on the blade; the brush can more effectively clean the plastic particles adhered on the stationary knife blade in time, improve the granulating effect and ensure the uniform shape of the plastic particles.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
