Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic structural diagram of the plastic extruder of the present invention.
Detailed Description
The utility model provides a plastic extruder, as shown in figure 1, which comprises a control system and an extrusion charging barrel 1, extrusion screw and hopper 2, extrusion screw locates in extruding feed cylinder 1 and by control system control work, hopper 2 locates the back end top of extruding feed cylinder 1, the bottom and the extrusion feed cylinder 1 intercommunication of hopper 2, the plastics extruder still includes weighing cylinder 3 and the conveyer belt 4 of pay-off to weighing cylinder 3, the discharge gate and the hopper 2 intercommunication of weighing cylinder 3, be equipped with weighing sensor 31 on the weighing cylinder 3, weighing sensor 31 is connected with control system electricity and sends the real-time weight information of weighing cylinder 3 to it, control system presets the upper limit value and the lower limit value of weighing cylinder 3, control system controls conveyer belt 4 and pay-off to weighing cylinder 3 when the weight of weighing cylinder 3 reaches the lower limit value and controls conveyer belt 4 to stop the pay-off when the weight of weighing cylinder 3 reaches the upper limit value.
The utility model discloses a weighing sensor 31 acquires the weight information of weighing cylinder 3, compare prior art and judge the inventory in hopper 2 through photoelectric signal, can not receive the influence of dust basically, not only the accuracy of acquireing information is better, the reliability is higher, be favorable to in time supplementing the material in weighing cylinder 3, weighing sensor 31 sends the real-time weight information of weighing cylinder 3 to control system in addition, can let the rate of use of control system real time monitoring material, whether normal operating is judged to the extrusion speed of cooperation plastics extruder, can in time shut down or report to the police when the machine appears unusually.
The discharge gate of weighing cylinder 3 and 2 intercommunications of hopper can be realized through the pipeline, also can be like this embodiment, directly stretch into hopper 2 with the bottom of weighing cylinder 3, and the discharge gate of weighing cylinder 3 is located hopper 2, saves the pipeline cost, but also can set up the shock absorber between weighing cylinder 3 and hopper 2, increases the stability of weighing cylinder 3 when receiving the material, such as cushion or sponge etc..
