Abstract
The utility model provides a vacuum decompression alarming isolation system of a plastic pipe production line, and the vacuum decompression alarming isolation system is characterized in that a vacuum shaping box and a plasticization screw rod are respectively provided with a pressure sensor, wherein the pressure sensors, a power supply switch, a pneumatic electromagnetic valve and an alarming lamp are connected onto an intermediate relay, the pneumatic electromagnetic valve is connected with an isolation wire, the power supply switch and the intermediate relay are installed inside a host control box, the alarming lamp is installed on the host control box, and the pneumatic electromagnetic valve is installed on a rack. The vacuum pressure abnormality caused by the deformation of a pipe is adopted as a signal source to realize an effect for isolating rejected projects and alarming prompting, so that the qualification rate of the products can be improved, and the inferior-quality product can be prevented from being mixed with the finished products.
Description
Technical field
The utility model belongs to the plastic tube product line technical field, specifically, relates to the vacuum decompression warning shielding system of this production line.
Background technology
Plastic pipe need be used vacuum tank in extruding the process of production, tubing sprays cooling during through vacuum tank, makes tube outer diameter, wall thickness, fineness reach production requirement.But in the running of production line, can not guarantee definitely that the negative pressure in the vacuum tank continues to remain on certain value, when negative pressure reduces, explain that the pipe workpiece quality of process vacuum tank is defective, external diameter is too small, has influenced moulding.Also do not have solution for this situation at present, the operator can not in time find, causes substandard products to mix with certified products, is difficult to distinguish, and has only the negative pressure problem that when apparent in view mass defect occurring, just can remove to check, control vacuum tank.
Summary of the invention
In order to solve the problem of above-mentioned proposition, the utility model provides a kind of substandard products of effectively avoiding to sneak in the certified products, and the plastic tube product line vacuum decompression warning shielding system that improves product quality and production efficiency is used following technical scheme:
A kind of plastic tube product line vacuum decompression warning shielding system; On the plasticized screw of vacuum shaping box and host computer control case, respectively be provided with a pressure inductor; Pressure inductor, power switch, air-operated solenoid valve and alarm lamp are connected on the auxiliary reclay, connect shielding wire on the air-operated solenoid valve, and power switch and auxiliary reclay are installed in the host computer control case; Alarm lamp is installed in above the host computer control case, and air-operated solenoid valve is installed on the bin.
Pressure inductor is sensed as vacuum switch; When pressure inductor is sensed the vacuum decompression; The vacuum switch contact point is connected, and makes auxiliary reclay work, and air-operated solenoid valve was opened and ejected shielding wire when alarm lamp was reported to the police; Substandard products and certified products are separated, be convenient to sort out fast and accurately substandard products.
The utlity model has following beneficial effect:
With because the vacuum pressure that the tubing distortion causes is a signal source unusually, reach waste product and isolate and alarm effect, improve product percent of pass, avoid substandard products to sneak into finished product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the electrical principle block diagram of the utility model.
The specific embodiment
To combine the accompanying drawing and the specific embodiment to come the utility model is done further detailed explanation below.
Like Fig. 1, shown in Figure 2; The plastic tube product line vacuum decompression warning shielding system of the utility model; On the plasticized screw of vacuum shaping box 1 and host computer control case 2, respectively be provided with a pressure inductor 3; Pressure inductor 3, power switch 4, air-operated solenoid valve 5 and alarm lamp 6 are connected on the auxiliary reclay 7, connect shielding wire 8 on the air-operated solenoid valve 5, and power switch 4 is installed in the host computer control case 2 with auxiliary reclay 7; Alarm lamp 6 is installed in above the host computer control case 2, and air-operated solenoid valve 5 is installed on the bin.
Pressure inductor 3 is a vacuum switch, and the vacuum switch contact point is connected, when the idling of taking seriously is pressed less than setting value, and auxiliary reclay 7 work; Start air-operated solenoid valve 5, eject shielding wire 8, certified products and substandard products are separated; And the startup alarm lamp, alert is debugged.The workman sorts out substandard products according to shielding wire 8 subsequently.
