Oppositely blowing type grain cutting cover device

Abstract

The invention discloses an oppositely blowing type grain cutting cover device which comprises a grain cutter, a motor and a cover body, wherein the cover body is fixed on the motor. The oppositely blowing type grain cutting cover is characterized in that the cover body is in a round structure, an air inlet pipeline and an air outlet pipeline are oppositely arranged at the bottom of the cover body, i.e., the openings of the air inlet pipeline and the air outlet pipeline are opposite and are arranged in the same straight line, and a round hole is arranged at the circle center of one side of the cover body; a cover body seat for fixing the cover body is arranged at the other side of the cover body, a sliding rail seat of a sliding rail is also arranged at the bottom of the cover body seat, a brake is arranged at the position of the bottom of the cover body seat contacting the sliding rail, and a window and a lighting lamp are also installed on the cover body. The invention facilitates the cover body of moving on the sliding rail through installing the sliding rail and the brake, temporarily stops the operation of the cover body seat on the sliding rail in time through braking, enables the cover body thereof to move away from the machine head of an extruding machine, is convenient for maintaining the machine head, clearing the inside of the cover body and observing the grain discharging condition of materials in the cover body and improves the production efficiency.

Description

technical field [0001] The invention relates to a pelletizing hood structure, in particular to a counter-blowing pelletizing hood device used for pelletizing materials in an extruder unit. Background technique [0002] In actual production, generally according to the type of polymer to be processed and the shape of the product or semi-finished product, select the extruder, head and die, as well as the corresponding auxiliary devices such as shaping and traction, and then determine the extrusion process conditions such as screw Speed, head pressure, material temperature, setting temperature, traction speed, etc. In the extrusion process, after the polymer is mixed with various additives, it is fed into the extruder to be melted, and further mixed evenly, passing through a multi-hole die to form multiple strips, and then cut into pellets. Cutting can be divided into hot dicing and cold dicing. After the former strip leaves the die, it is cooled by air or water and cut off im...

Problems solved by technology

However, the existing granulation hood is only a hood covering the head part, and one port is connected to a blower to blow the granulated material into the silo

When the granulation is completed, the remaining materials in the granulation hood or the machine head need to be maintained, the operator needs to disassemble the granulation hood for cleaning or maintenance. The operation is complicated, time-consuming and laborious, and reduces the production efficiency.
