Abstract
The utility model relates to a device for detecting a melting process of plastic particles. The device comprises an ultrasonic wave sensor (1), a waveguide pipe (2) with a cooling device, and a stirring rod (3), wherein the ultrasonic wave sensor (1) is used for periodically emitting and receiving an ultrasonic wave signal; the waveguide pipe (2) with the cooling device can transmit the ultrasonic wave signal sent by the ultrasonic wave sensor (1) and has a cooling effect; the stirring rod (3) is arranged in a mixing chamber of an internal mixer or an extruding machine; the stirring rod comprises a stirring head and a connecting rod; the waveguide pipe (2) with the cooling device comprises a front-end spiral tooth and the cooling device; the front-end spiral tooth is used for mounting the waveguide pipe on the internal mixer or the extruding machine. According to the device for detecting the melting process of the plastic particles, the normal-temperature ultrasonic wave sensor can be used for measuring the melting condition of the high-temperature plastic particles, the equipment is no longer processed in any form, and the processing cost of the equipment is effectively lowered.
Description
Technical field
The utility model relates to a kind of checkout gear, especially a kind of device that detects plastic grains fusion processes.
Background technology
In prior art, ultrasonic wave is used to detect the melting situation of plastic grains.Yet commercially available ultrasound sensors is used for greatly working under normal temperature environment, the maximum temperature can bear does not surpass 50 ℃, and while all surpassing 100 ℃ of above working environments in the face of plastic cement fusing point, commercially available ultrasound sensors cannot be used.
Summary of the invention
The technical problems to be solved in the utility model is to overcome prior art defect, and a kind of device that detects plastic grains fusion processes is provided.
For solving the problems of the technologies described above the technical scheme of employing, be: a kind of device that detects plastic grains fusion processes, comprise a ultrasound sensors (1), periodically transmitting and the super ripple sound wave signals of reception: the waveguide pipe of a tool cooling device (2), can transmit the sound wave signals sending from ultrasound sensors (1), and possess cooling effect; And one stirring rod (3) be placed in the mixing chamber of banbury or extruder, stirring rod comprises stirring-head and connecting rod; The waveguide pipe of tool cooling device (2) includes: a front end thread, is arranged on waveguide pipe on banbury or extruder; An and cooling device.
Ultrasound sensors is the compressional wave of normal temperature or cuts the sensor of waveform state, or the sensor of tool time delay; Stirring-head can be roller or gear.
The beneficial effect of this utility model is: the invention enables the ultrasound sensors of normal temperature can be used to measure the plastic grains melting situation of high temperature, and do not need again equipment to be carried out to any processing, can effectively reduce equipment processing cost.
Accompanying drawing explanation
Fig. 1 is the device profile that detects plastic grains course of dissolution;
Fig. 2 is the schematic diagram of ultrasonic sensor and waveguide pipe;
Fig. 3 is the side view of stirring rod.
1-ultrasound sensors, the waveguide pipe of 2-tool cooling device, 3-stirring rod, 4-mixing chamber, 5-cooler, 6-thread, 7-waveguide pipe, the stirring-head of 8-roller shape, 9-connecting rod.
The specific embodiment
Before plastic grains is put into the mixing chamber of banbury, the temperature that mixing chamber is heated to a setting (for example: the melting temperature of plastic material), and stirring rod (3) operates at the rotating speed of setting, now ultrasonic signal is sent by sensor (1), via waveguide pipe (2), reaches in mixing chamber (4) and is reflected back sensor again.If the plastic cement in mixing chamber has melted, ultrasonic signal passes the plastic cement liquid into melting, after stirring rod, is reflected back sensor again.But general commercially available ultrasound sensors (1) is the highest can only bear 50 ℃, surpass the just fusing of foam structure in temperature sensor, cause sensor impaired and cannot use; Between sensor and mixing chamber, add a waveguide pipe (2), but, general waveguide pipe is comprised of glass or plastic cement acrylic, Glass breadks easily, and plastic cement acrylic cannot Nai Gaore, therefore the present invention proposes the waveguide pipe consisting of metal, can bear high heat (at least 1000 ℃), and tool toughness; In waveguide pipe, near one end of sensor, add cooling device, high heat rejection mixing chamber being transmitted by cooling device, waveguide pipe can be maintained below 40 ℃ near the temperature of sensor one end, commercially available normal temperature ultrasound sensors (1) can normally be worked, be not subject to the high heat affecting of mixing chamber.Stirring rod in mixing chamber, it is main is grind and stir plastic grains, comprises roller, gear etc.
Claims (2)
1. a device that detects plastic grains fusion processes, it is characterized in that: comprise a ultrasound sensors (1), periodically transmitting and the super ripple sound wave signals of reception: the waveguide pipe of a tool cooling device (2), can transmit the sound wave signals sending from ultrasound sensors (1), and possess cooling effect; And one stirring rod (3) be placed in the mixing chamber of banbury or extruder, stirring rod comprises stirring-head and connecting rod; The waveguide pipe of tool cooling device (2) includes: a front end thread, is arranged on waveguide pipe on banbury or extruder; An and cooling device.
2. the device of detection plastic grains fusion processes as claimed in claim 1, is characterized in that: the compressional wave that ultrasound sensors is normal temperature or cut the sensor of waveform state, or the sensor of tool time delay; Stirring-head can be roller or gear.
