Raw material preheating device for capacitor plastic shell processing

Abstract

The invention discloses a raw material preheating device for capacitor plastic shell processing, and relates to the technical field of capacitor plastic shell processing. The device comprises a preheating box, wherein the preheating box is obliquely arranged, the top of the upper end of the preheating box communicates with a feeding channel, the lower end of the preheating box communicates with a discharging channel, a driving roller, a driven roller and a conveying belt connecting the driving roller and the driven roller are arranged in the preheating box, and the driving roller and the driven roller are driven by a driving mechanism to rotate; a plurality of downward pressing mechanisms and jacking structures are arranged between the driving roller and the driven roller, the downward pressing mechanisms and the jacking structures are arranged in a staggered mode, the conveying belt penetrates through the downward pressing mechanisms and the jacking structures to form a continuous wavy structure, and guide rollers used for guiding the conveying belt are symmetrically arranged at two ends of the wavy structure; a heat insulation cover is fixedly connected to the inner top wall of the preheating box, and an infrared heating lamp tube is fixedly connected into the heat insulation cover. Defects in the prior art are overcome, plastic raw materials are evenly preheated, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of capacitor plastic case processing, in particular to a raw material preheating device used for capacitor plastic case processing. Background technique [0002] During the processing of the capacitor plastic case, the plastic raw material needs to be heated and melted, and then the molten plastic is injected into the required shape through the mold. [0003] During the processing of the existing plastic raw material extruder, the plastic raw material particles are generally added directly into the extruder through the hopper at room temperature. After entering the extruder, under the heating of the screw and the barrel, the plastic is melted by shearing, and the molten plastic is sent to the mold or flow channel for processing through the rotation of the screw. This conventional processing process makes the plastic raw materials enter the extruder from the hopper at room temperature. The initial temperatur...

Problems solved by technology

This conventional processing makes the plastic raw materials enter the extruder from the hopper at normal temperature. The initial temperature of the plastic raw materials depends entirely on the ambient temperature. When the raw materials first enter the barrel, due to the low temperature of the plastic raw materials Before it has time to melt, the screw needs to expend a lot of driving force to extrude and push the plastic material forward, which reduces the processing efficiency
