Abstract
The present invention discloses a twin screw extruder with an automatic material feeding function. The twin screw extruder comprises screws, a material cylinder and a material hopper, wherein the screws are arranged inside the material cylinder, a material outlet of the material hopper is communicated with the material cylinder, the screws are connected with a power device, a material inlet of the material hopper is provided with an electric material feeding valve, the top of the material hopper is provided with a material level meter, and the material level meter and the electric material feeding valve form electrical connections with a control device. According to the present invention, the material level meter is arranged and is provided for measuring a height of a material inside the material hopper at any time, the material level meter and the control device are connected, and the automatic material feeding valve can be controlled to automatically carry out material feeding on the material hopper when the material inside the material hopper is insufficient so as to reduce workload of workers, provide safety and reliability, and effectively ensure production efficiency.
Description
Technical field
The present invention relates to double screw extruder, relate in particular to a kind of double screw extruder with automatic material compensation function.
Background technology
Extruder can be divided into extruding continuously with discontinuous by type of action to be extruded.Need feed not to be interrupted in extruding continuously, traditional extruder feeding device need to rely on the supply of material in the Artificial Control hopper, so that hopper can be in time to the extruder feed, this situation waste of manpower, thus the workman neglects and easily causes the temporary transient material that lacks to affect production sometimes.
Summary of the invention
The technical problem that the present invention solves is: provide a kind of and have the double screw extruder with automatic material compensation function of automatic material compensation function to guarantee the continuous production of product.
For reaching this purpose, the present invention by the following technical solutions:
A kind of double screw extruder with automatic material compensation function, comprise screw rod, barrel and hopper, described screw rod is arranged in the barrel, described hopper discharging opening is connected with barrel, described screw rod connecting power device, described hopper feed mouth is provided with electronic feed supplement valve, and described hopper top is provided with level-sensing device, and described level-sensing device, electronic feed supplement valve all are electrically connected with control device.
Further, described screw rod is by the decelerator connecting power device, and described power set are motor.
Further, be provided with heater on the described barrel.
Further, be provided with steam vent on the described barrel.
Further, be connected by the diaphragm-type shaft coupling between described decelerator and the power set.
Beneficial effect of the present invention is: be provided with level-sensing device and can measure at any time height of materials in the hopper, level-sensing device is connected with control device can be controlled automatic feeding valve automatic feeding bucket and carry out feed supplement when material in the hopper is not enough, reduced workman's workload, more safe and reliable, can effectively guarantee production efficiency.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is traditional filter screen installment state upward view.
Among the figure:
1, screw rod; 2, barrel; 3, hopper; 4, motor; 5, electronic feed supplement valve; 6, level-sensing device; 7, decelerator; 8, heater; 9, steam vent; 10, diaphragm-type shaft coupling.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, in the present embodiment, a kind of double screw extruder with automatic material compensation function of the present invention, comprise screw rod 1, described screw rod 1 is arranged in the barrel 2, and described barrel 2 tops are provided with hopper 3, and described hopper 3 discharging openings are communicated with barrel 2, described hopper 3 charging apertures are provided with electronic feed supplement valve 5, and described hopper 3 tops are provided with level-sensing device 6; Described electronic feed supplement valve 5 all is electrically connected control device with level-sensing device 6.
Described screw rod 1 connects motor 4 by decelerator 7, is connected by diaphragm-type shaft coupling 10 between described motor 4 and the decelerator 7, is provided with steam vent 9 and heater 8 on the described barrel 2, and described heater 8 is a plurality of surperficial uniform at barrel 2.
Material during extruder work in the hopper 3 enters barrel 2 and is extruded the machine extrusion molding, in the Continuous Extrusion Process when the interior materials of hopper 3 are not enough level-sensing device 6 record the material level data and send control device to, after control device receives signal, control in 5 pairs of hoppers 3 of electronic feed supplement valve and feed in raw material, the highest numerical value timed unit that reaches regulation when hopper 3 interior materials is controlled electronic feed supplement valve 5 and is stopped feed supplement.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present invention and institute's application technology principle; in technical scope disclosed in this invention, the variation that any those skilled in the art of being familiar with easily expected or replacement all should be encompassed in protection scope of the present invention.
