Pneumatic ram fully sealed feeding and discharging port of plastic powder mixing drum

Abstract

The invention discloses a full-sealed feeding and discharging hole of a pneumatic shutter of a plastic powder mixing cylinder. The full-sealed feeding and discharging hole comprises a cylinder body of the mixing cylinder, wherein a feeding and discharging hole is formed in the cylinder body. The full-sealed feeding and discharging hole is characterized in that a cover plate is arranged around the feeding and discharging hole, a shutter base is arranged on the cover plate, a left shutter groove and a right shutter groove are respectively formed in the left side and the right side of the shutter base, pressing plates are arranged on the left shutter groove and the right shutter groove, a left shutter and a right shutter are respectively arranged between the left shutter groove and the corresponding pressing plate and between the right shutter groove and the corresponding pressing plate, the inner end faces of the left shutter and the right shutter are in contact and are provided with sealing devices, the outer side end of the left shutter is connected with a left cylinder, the outer side end of the right shutter is connected with a right cylinder, and the left cylinder and the right cylinder respectively drive the left shutter and the right shutter to be opened or closed. The cylinders automatically drive the shutters to be opened or closed, and thus the full-sealed feeding and discharging hole is suitable for automatic production, and is high in speed, good in sealing property and high in production efficiency.

Description

technical field [0001] The invention relates to a fully-sealed feeding and discharging opening of a mixing cylinder pneumatic gate used for a fully automatic dust-free plastic powder mixer, belonging to the field of plastic powder mixing equipment. Background technique [0002] When producing plastic specification (decorative) panels, in order to meet the quality requirements, it is necessary to mix a variety of plastic powders (plastic powder) with different characteristics before processing. During processing, first pour all kinds of plastic powder raw materials into the feeding bin, and then transport all kinds of plastic powder to the mixing cylinder for mixing by the feeding auger, after stirring evenly, then send it to the storage tank for cooling, after cooling, The plastic powder is sent to the processing equipment by the unloading auger for processing and molding. The traditional mixing cylinder has feeding and discharging ports, and there are covers on the feeding...

AI Technical Summary

Problems solved by technology

The traditional mixing cylinder has feeding and discharging ports, and there are covers on the feeding and discharging ports. In the existing technology, the plastic powder is sent into the mixing cylinder for stirring and the stirred plastic powder is sent to the storage cylinder. It can only be carried out after the cover is removed manually. After the feeding is completed, the cover is manually closed. The requirements for automatic opening and closing cannot be realized, and automatic production cannot be achieved. The production speed is slow, the efficiency is low, and the sealing performance is poor. The powder is easy to fall out of the cylinder
