Abstract

The utility model discloses a plastic extruding machine with a regular preheating function. The plastic extruding machine comprises an extruding system, a transmission system and a heating and cooling system, wherein the extruding system comprises a screw rod, a machine barrel, a hopper, a machine head and a die; the transmission system comprises a motor, a speed regulation device and a speed reducer; the heating and cooling system comprises a resistance heating device and a control system and further comprises a timing counter electrically connected with the control system; the control system receives timing counting signals of the timing counter to drive the heating and cooling system so as to heat the resistance heating device, so that the control system can drive the heating and cooling system regularly everyday through setting the timing counter, and the resistance heating device can preheat the plastic extruding machine in advance; and therefore, when a worker is on the job, the plastic extruding machine can be in a working state immediately, further, the problem that the time of workers is wasted due to preheating can be avoided, and the production efficiency is improved.

Description

A kind of extruding machine with timing preheat function

Technical field

The utility model relates to a kind of extruding machine, is specifically related to a kind of regularly extruding machine of preheat function that has.

Background technology

The operation principle of extruding machine is: the screw rod that utilizes given shape, in cartridge heater, rotate, to be pushed forward by the plastics of sending here in the hopper, make plastics plastify equably (being melting), by head and difform mould, make plastic extrusion become the plastic layer of successional needed various shapes, be extruded on core and the cable.

The plastic insulation of electric wire and sheath adopt continuously extruded mode to carry out, and extrusion equipment generally is to adopt single multiple screw extruder.Whether extruding machine wants the precheck plastics moist or have or not other foreign material, then adding in the material bin after the plastics preheating before extruding.In extrusion, the plastics in the hopper of packing into enter in the machine barrel by gravity or reinforced spiral, constantly push ahead under the thrust of rotary screw, begin little by little to move to the homogenizing stage from preheating section; Simultaneously, plastics are subject to stirring and the squeezing action of screw rod, and change viscous state under the effect of the outer heat of machine barrel and the shearing friction heat between plastics and the equipment, form the material stream of continuous uniform in screw channel.Under the temperature action of process stipulation, plastics change the plastic object of melting state into from solid state, via promotion or the stirring of screw rod, the plastic heap that plasticizing is good is fully entered head again, arrive the material stream of head, annular gap through between core rod and die sleeve, extrude from the die sleeve mouth, extrude around main line core or the cable core, form continuously closely knit insulating barrier or restrictive coating, then through cooling and curing, make the electric wire product.

Current, when the staff goes to work, first the extruding machine preheated one-section time is then just started working, so, will waste staff's working time, affect production efficiency.

The utility model content

For the problem that prior art exists, the purpose of this utility model is to provide a kind of regularly extruding machine of preheat function that has.

A kind of extruding machine with timing preheat function that the utility model provides, it comprises extrusion system, transmission system and heating and cooling system, wherein, described extrusion system comprises screw rod, machine barrel, hopper, head and mould, described transmission system comprises motor, arrangements for speed regulation and decelerator, described heating and cooling system comprises resistance heater and control system, comprise that further timer conter and described control system are electrically connected, the timer counter signal that described control system receives described timer conter drives described heating and cooling system, makes described resistive heater heats.

Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:

In a kind of extruding machine that has regularly a preheat function that the utility model provides, it comprises that timer conter and described control system are electrically connected, the timer counter signal that described control system receives described timer conter drives described heating and cooling system, make described resistive heater heats, thereby, can be by the setting to described timer conter, make described control system regularly drive described heating and cooling system every day, make described resistive heater heats, to carry out preheating as described extruding machine in advance, thereby, the preheating of described extruding machine is finished when the staff goes to work, can directly enter duty, thereby, can save the time of wasting the staff because of preheating to enhance productivity.
