Abstract

The utility model discloses a plastic extruding machine capable of discharging water and low molecular-weight outflowing matters produced by plastics during heating. The plastic extruding machine comprises a rack, a machine barrel arranged on the rack, a gearbox and a driving motor, wherein a screw rod is movably arranged in the machine barrel, and one end of the screw rod is connected with an output shaft of the gearbox; and an exhaust port is arranged at the middle part of the machine barrel, and the exhaust port is connected with a vacuum machine through an exhaust pipeline. As the exhaust port is arranged on the machine barrel, and the exhaust port is connected with the vacuum machine through the exhaust pipeline, water and low molecular-weight outflowing matters produced by plastics during heating can be discharged outwards, thereby ensuring the quality of finished products.

Description

A kind of plastic extruder
Technical field
The utility model relates to plastic hot processing machinery, refers more particularly to a kind of plastic extruder.
Background technology
Present plastic extruder, its structure comprises: frame and be arranged on machine barrel, reduction box and drive motors on the frame, be movably set with screw rod in the machine barrel, an end of screw rod links to each other with the output shaft of reduction box.In actual use, owing to do not have exhaust outlet on the machine barrel, moisture content that plastics produce in heating process and low molecule lapaxis can't be discharged, and have influence on the quality of finished product.
The utility model content
Technical problem to be solved in the utility model is: the plastic extruder that provides a kind of moisture content that plastics can be produced in heating process and low molecule lapaxis to discharge.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: plastic extruder, comprise: frame, be arranged on machine barrel, reduction box and drive motors on the frame, be movably set with screw rod in the machine barrel, an end of screw rod links to each other with the output shaft of reduction box; The middle part of described machine barrel offers exhaust outlet, and exhaust outlet links to each other with the vacuum machine by gas exhaust piping.
Described gas exhaust piping is provided with pressure sensor.
The beneficial effects of the utility model are: owing to offer exhaust outlet on the machine barrel, and exhaust outlet links to each other with the vacuum machine by the exhaust passage, thus moisture content that plastics can be produced in heating process and low molecule lapaxis discharge, and have guaranteed the quality of finished product.In addition,, can control the start and stop of vacuum machine automatically on gas exhaust piping, realize the exhaust automation by pressure sensor is set.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, frame, 2, machine barrel, 21, exhaust outlet, 3, screw rod, 4, reduction box, 5, drive motors, 6, shaft coupling.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, plastic extruder described in the utility model comprises: frame 1, be arranged on machine barrel 2, reduction box 4 and drive motors 5 on the frame 1, be movably set with screw rod 3 in the machine barrel 2, an end of screw rod 3 links to each other with the output shaft of reduction box 4 by shaft coupling 6; The middle part of described machine barrel 2 offers a pair of exhaust outlet 21, and exhaust outlet 21 links to each other with the vacuum machine by gas exhaust piping; Described gas exhaust piping is provided with pressure sensor, and vacuum machine, gas exhaust piping and pressure sensor all belong to conventional techniques, do not draw among the figure.
During use, according to the pressure sensor on the gas exhaust piping, control the start and stop of vacuum machine automatically, realized the exhaust automation, moisture content and low molecule lapaxis that plastics are produced in heating process discharge, and have guaranteed the quality of finished product.
