Plastic particle extruding production equipment for carrying out polyvinyl chloride smoke dechlorinating through S-shaped screw rod

Abstract

The invention discloses plastic particle extruding production equipment for carrying out polyvinyl chloride smoke dechlorinating through an S-shaped screw rod. The structure of the equipment comprisesa hand-dragging gate, an alloy base, an S-shaped pelleting device, a stepping motor rack, a hopper, a gear transmission box, a belt wheel and a base. According to the equipment, the S-shaped pelleting device is adopted and matched with the hopper, the material blocking effect that an S-shaped screw rod frame drives an arc cover wing spread plate to rub with a kickback-resisting plastic block up and down is achieved, the compression moulding effect that the unformed plastic block is rotated back continuously to an injection mould cover plate is achieved, by means of the S-shaped rotation track, the hopper is in butt joint with a conveying groove, a certain space exists in the middle, stacked plastic particles are output intermittently in batches to form products for step-by-step sample detection, the phenomenon of shell blocking is improved, an external supporting steel pin brush plate cuts and crushes the plastic block, plastic powder is added into the screw rod again for machining, waste materials are utilized cyclically, the production quality and the homogeneity effect are improved, it is guaranteed that polyvinyl chloride is spirally rotated and filled into along with smoke for precipitating chlorine elements, and the effect of pollution-free and environment-friendly processing of polyethylene is achieved.

Description

technical field [0001] The invention relates to plastic granule extrusion production equipment for polyvinyl chloride flue gas serpentine screw dechlorination, and belongs to the field of plastic granule production equipment. Background technique [0002] Plastic granule extrusion production equipment is the preferred production equipment for granule plastic parts such as mica granules. Because the feeding funnel is convenient, and then cooperates with the screw rotary mold to output molded parts after die-casting, it achieves the convenience of long-distance transportation and improves the combination of granulation equipment. The operating efficiency of high-precision mold molding, the disadvantages of the current technology that need to be optimized are: [0003] The screw rod of the plastic granulator cooperates with the bottom frame of the hopper to form an overhead rotation phenomenon, which will cause the die-casting pellets of the machine head and the mold to recoil,...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a plastic granule extrusion production equipment for polyvinyl chloride flue gas serpentine screw dechlorination, so as to solve the problem that the screw of the plastic granulator is combined with the bottom frame of the hopper to form an overhead rotation. Phenomenon, this will cause feed recoil to the die-casting pellets of the machine head and the mold, which will cause the plastic block to be centrifugally thrown upwards and out of the frame when the pellets are not completely pelletized, thereby disturbing the uniformity of continuous feeding and making the pelletizing process The probability of agglomeration is too high, which leads to the phenomenon of screw rotation jamming and hardware lock-up. It is necessary to manually crush hard plastic blocks, which consumes labor and delays the progress of the project. The homogeneity of the two granulations before and after leads to the low pass rate of the later product inspection
