Plastic particle injection molding preheating treatment equipment

Abstract

The invention provides plastic particle injection molding preheating treatment equipment which comprises a preheating box and a discharging plate, and heat protection assemblies capable of preventing the surface temperature of the discharging plate from being too high are movably installed at the front end and the rear end of the discharging plate. The heat-proof assembly comprises heat-proof shells, a right processing assembly and a left processing assembly, the right processing assembly can release one kind of cooling materials after the heat temperature is transmitted in, and the left processing assembly can release the other kind of cooling materials after the heat temperature is transmitted in; a right processing assembly and a left processing assembly are movably installed at the upper right end and the upper left end in the heat-proof shell correspondingly. According to the plastic particle injection molding preheating treatment equipment, the heat-proof function can be achieved outside the discharging plate, when plastic particles preheated through the preheating box are discharged outwards through the discharging plate, even if high-temperature heat is brought to the discharging plate, the heat outside the discharging plate can be digested in time, and therefore the plastic particles are discharged out of the discharging plate. And the safety accident that workers are scalded when making contact with the surface of the discharging plate by mistake is avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, and more specifically, to a preheating treatment equipment for injection molding of plastic particles. Background technique [0002] The plastic granule preheating device of the injection molding machine in the prior art cannot crush the plastic with large granules when used, and cannot recover the heat generated during preheating well, which is easy to cause great waste. The temperature can be adjusted during use. sex is relatively poor. [0003] In view of the above problems, regarding the technical problem that the plastic particle preheating device of the existing injection molding machine cannot crush the plastic with large particles, etc., after a large number of searches, we found an injection molding machine with the patent number CN201920085299.3 The plastic pellet preheating device includes a preheating box. The top outer wall of the preheating box is fixed with a fe...

AI Technical Summary

Problems solved by technology

[0002] The plastic granule preheating device of the injection molding machine in the prior art cannot pulverize the plastic with large granules when used, and cannot well recover the waste generated during preheating. heat, it is easy to cause great waste, and the temperature can be adjusted poorly during use

[0003] In view of the above-mentioned problems, regarding the technical problem that the plastic particle preheating device of the existing injection molding machine cannot crush the plastic with large particles, etc., after a lot of Retrieval, found a plastic pellet preheating device for injection molding machine whose patent number is CN201920085299.3. There is a PLC control board, and there is a discharge hole on one side of the outer wall of the preheating box, and a discharge plate is fixed on one side of the inner wall of the discharge hole by bolts, and a drive motor is fixed on one side of the preheating box by bolts. One end of the output shaft is connected to the rotating rod through a coupling, and the inside of the preheating box is provided with a transmission rod and a connecting rod with sleeve bearings at both ends; Rotating under rotation can well cut the larger particles into smaller particles, reducing the preheating time. At the same time, the crushing cutter head can cooperate with the rotating rod and the transmission rod to make the plastic particles roll inside the preheating box. It is convenient to preheat the plastic particles, but the technical solution provided by this patent does not have the heat-proof function for the outside of the discharge plate. When the plastic particles preheated by the preheating box are discharged through the discharge plate, the high-temperature heat It is easy to be brought to the discharge plate. If the heat outside the discharge plate is not dissipated in time, the staff is prone to be scalded by it when they mistakenly touch the surface of the discharge plate.
