Embodiment Construction

[0021] Such as Figure 1-3 As shown, the sheet extruder with the melt pressure control system in this preferred embodiment includes a fuselage 1, a host machine 2, a metering pump 3, a filter screen 4, and a melt pressure control system, and the host machine 2, metering The pump 3, the filter screen 4, and the melt pressure control system are installed on the fuselage 1 respectively.

[0022] The melt pressure control system includes

[0023] The pressure detection mechanism detects the melt pressure at three places of the sheet extruder and sends out a pressure detection signal;

[0024] The control device receives and processes the pressure detection signal, and sends out the speed regulation control signal;

[0025] The speed regulating mechanism receives two speed regulating control signals and controls the speed of the corresponding driving motor.

[0026] The pressure detection mechanism includes a first pressure sensor 5, which detects the melt pressure in front of t...

Abstract

The invention discloses a sheet extruding machine with a melt pressure control system. The sheet extruding machine comprises a machine body, a main engine, a metering pump, a filter screen and the melt pressure control system, wherein the main engine, the metering pump, the filter screen and the melt pressure control system are respectively arranged on the machine body. The sheet extruding machine is characterized in that the melt pressure control system comprises a pressure detection mechanism, a control device and a speed regulating mechanism, wherein the pressure detection mechanism is used for detecting at least one position melt pressure of the sheet extruding machine so as to send a pressure detection signal; the control device is used for receiving the pressure detection signal and process so as to send speed regulating control signals; the speed regulating mechanism is used for receiving at least one speed regulating control signal and controls the rotating speed of the corresponding drive motor. Compared with the prior art, the sheet extruding machine provided by the invention has the beneficial effects that the melt pressure control system is capable of detecting melt pressure in real time, the melt pressure is regulated and can keep the appropriate range all the time, thus the quality of a sheet manufactured by the sheet extruding machine is effectively guaranteed.

Description

technical field [0001] The present invention relates to a sheet extruder, more particularly to a sheet extruder with a melt pressure control system. Background technique [0002] The sheet extruder extrudes the sheet through the die head. Under the conventional control operation, it is necessary to have a rich work experience and a good understanding of the material properties to make a better quality plastic sheet, which is very wasteful. time and manpower. [0003] This is because after the plastic is melted into a melt, the pressure of the melt is difficult to control, and if the pressure changes, it will adversely affect the quality of the extruded sheet. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a sheet extruder with a melt pressure control system in view of the shortcomings of the prior art that the melt pressure is difficult to control. This sheet extruder with a melt pressure control syste...
