Problems solved by technology

In the extrusion granulation process, the extruded plastic is cooled by water first, and then enters the granulator. The plastic contains a lot of water. In addition, the plastic particles are exposed to moisture in the air, which will seriously affect the chemical properties of the plastic product. In addition, if Impurities enter the barrel with the plastic, which can easily cause damage to the equipment. In addition, due to the high temperature of the die, it is easy to cause the output to fail to form strips and stick to the die.

Embodiment 1

[0013] The invention provides a modified plastic granulator, which includes a metal cylinder 1, a feed hopper 2, a motor 3, a hot air blower 4, a filter device 5, a conveying roller 6, a heater 7, an exhaust hole 8, a sewage hole 9, Die head 10, cooling water inlet pipe 11, cooling water outlet pipe 12, feeding hopper 2 is arranged on the upper end of metal cylinder 1, filter device 5 is arranged between feeding hopper 2 and metal cylinder 1, and on the inner wall of feeding hopper 2 A hot air blower 4 is installed, and a conveying roller 6 is installed inside the metal cylinder 1. The conveying roller 6 is connected to the motor 3. A heater 7 is installed on the conveying roller 6. The metal cylinder 1 is provided with an exhaust hole 8 and a sewage discharge hole 9 below. A die head 10 is installed behind the conveying roller 6, a cooling water inlet pipe 11 is provided above the die head, and a cooling water outlet pipe 12 is provided below.

Embodiment 2

[0015] When working, the modified plastic particles are put into the upper hopper 2, and the hopper 2 is equipped with a hot air blower 4, which can play a role in drying the feed material, and avoid the wet modified plastic particles from entering to cause low product quality. The filter device 5 filters Modified plastic particles absorb metal waste and dust to avoid damage to equipment. The filtered modified plastic particles enter the metal cylinder 1, and the transmission roller 6 drives the modified plastic particles to move forward. The transmission roller 6 is equipped with a heater 7. Electromagnetic heating, the temperature rises quickly. The metal cylinder 1 is provided with an exhaust port 8 and a sewage outlet at the bottom to facilitate the discharge of the hot gas accumulated in the metal cylinder and the sewage left during cleaning. The transfer roller 6 will modify the The plastic particles are sent to the die head 10 and extruded by the die head 10. A cooling w...

Abstract

A modified plastic granulator comprises a metal cylinder, a feeding hopper, a motor and the like. The modified plastic granulator is characterized by further comprising an air heater, a filtering device, a cooling water inlet pipe and a cooling water outlet pipe, the feeding hopper is arranged at the upper end of the metal cylinder, the filtering device is arranged between the feeding hopper and the metal cylinder, the air heater is arranged on the inner wall of the feeding hopper, a conveying roller is mounted in the metal cylinder and connected with the motor, and a heater is mounted on the conveying roller. The modified plastic granulator has the advantages that the air heater is arranged on the inner wall of a feeding port, so that the problem of low product quality caused by entering of moist modified plastic granules is avoided; since the filtering device is added between the feeding port and the metal cylinder, equipment damage degree can be decreased, equipment service life can be prolonged and product quality can be improved; the cooling water inlet pipe and the cooling water outlet pipe are arranged above and below a mould head respectively, and accordingly, die head cooling speed is increased, the situations that discharged materials are not in strips and stuck on the mould head are avoided, and the product quality is further improved.

Description

technical field [0001] The invention relates to a granulator, in particular to a modified plastic granulator. Background technique [0002] Modified plastics refer to plastic products that are processed on the basis of general-purpose plastics and engineering plastics through filling, blending, and reinforcement to improve their performance in terms of flame retardancy, strength, impact resistance, and toughness. In the extrusion granulation process, the extruded plastic is cooled by water first, and then enters the granulator. The plastic contains a lot of water. In addition, the plastic particles are exposed to moisture in the air, which will seriously affect the chemical properties of the plastic product. In addition, if Impurities enter the barrel with the plastic, which can easily cause damage to the equipment. In addition, due to the high temperature of the die, it is easy to cause the discharge material to fail to form strips and stick to the die. Contents of the in...
