Abstract
In the plastic processing industry, when in the material feeding process of a feeding pipe, the power is small in size so as to be easy to block under the feeding pipe, and if the power is not cleaned in time, a screw rod of a main machine can be blocked to result in fault. According to the problem, the utility model provides a material feeding and blocking alarm of the plastic extruder which can send alarm when the feeding pipe is blocked. When the material block occurs, the material returns upwards along the feeding pipe, and contacted with an overturning plate to push the feeding pipe to rotate upwards, at the time, a magnetic sensor senses the change of a magnetic field, then signals are sent to the alarm, and finally the alarm is generated.
Description
Technical field
The utility model relates to plastic extruder feeding material jam warning field, relates in particular to a kind of feeding material jam alarm of plastic extruder.
Background technology
In the plastic processing industry, after various pellets and powder mixed through batch mixer, the vertical tremie pipe that is delivered to plastic extruder by feed screw fed in raw material.In the blanking process of tremie pipe, diameter of particle is little, gets lodged in the below of tremie pipe easily; Conveying gap at screw rod forms accumulation; Compound can't in time get into extrusion screw rod at main spout, thereby causes the returning charge phenomenon at main spout, if untimely cleaning; Cause the stuck of main-machine screw easily, break down.
The utility model content
The utility model provides a kind of feeding material jam alarm of plastic extruder to existing problem.This device comprises extruder, tremie pipe, fixed head, returning face plate, alarm, Magnetic Sensor, rotating shaft, support.
Side at tremie pipe is equipped with a returning face plate, and the rotating shaft of returning face plate central authorities is positioned at the sidewall of tremie pipe, and half of returning face plate is in tremie pipe, and be half the outside tremie pipe.
The outside half the top of returning face plate is provided with fixed head, and the below is provided with Magnetic Sensor, links to each other with alarm through electric wire.
Described returning face plate is that magnetic material is made;
Described Magnetic Sensor is fixed on the support of tremie pipe outer wall.
The feeding material jam alarm of the plastic extruder that the utility model provides can give the alarm to the putty of tremie pipe.When putty not taking place, Magnetic Sensor is experienced certain magnetic signal, at this moment, through the setting of circuit, can be as a reference this magnetic signal, at this moment, siren can not reported to the police; When putty took place, material returned on tremie pipe, when touching returning face plate, promoted it and upwards rotated, and at this moment, the magnetic field that Magnetic Sensor is experienced changes, and signal feedback to siren alarm takes place.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, extruder, 2, tremie pipe, 3, fixed head, 4, returning face plate, 5, alarm, 6, Magnetic Sensor, 7, rotating shaft, 8, support
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model, comprises that this device comprises extruder 1, tremie pipe 2, fixed head 3, returning face plate 4, alarm 5, Magnetic Sensor 6, rotating shaft 7, support 8.Wherein, in a side of tremie pipe 2 returning face plate 4 is housed, the rotating shafts 7 of returning face plate 4 central authorities are positioned at the sidewall of tremie pipe, returning face plate 4 half the in tremie pipe 2, half the outside tremie pipe 2.Returning face plate 4 outside half the tops are provided with fixed head 3, and the below is provided with Magnetic Sensor 6, links to each other with alarm 5 through electric wire.Described returning face plate 4 is made for magnetic material; Described Magnetic Sensor 6 is fixed on the support 8 of tremie pipe outer wall.
The feeding material jam alarm of the plastic extruder that the utility model provides can give the alarm to the putty of tremie pipe 2.When putty not taking place, Magnetic Sensor 6 is experienced certain magnetic signal, at this moment, through the setting of circuit, can be as a reference this magnetic signal, at this moment, siren can not reported to the police; When putty took place, material returned on tremie pipe 2, and when touching returning face plate 4, returning face plate upwards rotates along rotating shaft 7, and at this moment, the magnetic field that Magnetic Sensor 6 is experienced changes, and signal feedback to siren 5 alarm takes place.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
