Description
Technical field
The utility model relates to a kind of underwater pelletizer putty pick-up unit.
Background technology
Underwater pelletizer adopts optoelectronic switch to carry out " wrapper " putty and detects; when putty detects optoelectronic switch action; guide head can be got to the position of waste discharge by control system according to the chain condition of setting in advance; make follow-up adhesive tape can not continue to enter the accumulating amount reducing polymkeric substance in boundling guide plate, reduce cleaning task afterwards amount.But owing to there are following two shortcomings, actual effect is not satisfactory:
(1) the putty drop point site that detects the optoelectronic switch position not good adhesive tape owing to getting off from die head from optoelectronic switch very close to, slightly deviation will the light eye of shading light electric switch, and cause optoelectronic switch misoperation, pelleter cannot normally pelletizing.When putty phenomenon appears in pelleter, also because putty optoelectronic switch position is higher, cannot realize putty the very first time and detect, polymkeric substance bulk deposition causes pelleter " chartered plane ".
(2) putty optoelectronic switch is subject to water vapour affects underwater pelletizer in pelletizing process, needs overflow water and shower water to cool high temperature adhesive tape; a large amount of water vapour can be produced in adhesive tape cooling procedure; water vapor moves upward the light that also may have influence between optoelectronic switch transmitter and receiver, causes optoelectronic switch misoperation.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of underwater pelletizer putty pick-up unit.
The utility model solves the technical scheme that its technical matters adopts: a kind of underwater pelletizer putty pick-up unit, for preventing the material putty between guide head and cutting knife group, comprise and be installed on the boundling guide plate be obliquely installed between guide head and cutting knife group and be installed on the putty switch that boundling leads, boundling guide plate has the groove of the directing material advance be arranged side by side, putty switch is one group of optical fiber correlation optoelectronic switch, putty switch is positioned at the boundling guide plate side from boundling guide plate bottom 1/3 distance, putty switch comprises the transmitter and receiver that lay respectively at boundling guide plate both sides, the infrared measurement of temperature pick-up unit that an investigative range can cover whole boundling guide plate is installed above boundling guide plate.
Further, infrared measurement of temperature pick-up unit is formed by one group of four infrared temperature probe and is fixed on support, and infrared measurement of temperature pick-up unit (5) is installed on the position of 30 °, boundling guide plate (1) front upper place.
Further, putty switch and infrared measurement of temperature pick-up unit all with PLC connection.
The beneficial effects of the utility model are: optoelectronic switch displacement improve putty detect reliability, but infrared measurement of temperature pick-up unit decrease be subject to water vapour impact there is misoperation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. boundling guide plate, 2. groove, 3. transmitter, 4. receiver, 5. infrared measurement of temperature pick-up unit.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of underwater pelletizer putty pick-up unit as shown in Figure 1, for preventing the material putty between guide head and cutting knife group, comprise the boundling guide plate 1 be obliquely installed be installed between guide head and cutting knife group and the putty switch be installed on boundling guide plate 1, boundling guide plate 1 has the groove 2 of the directing material advance be arranged side by side, putty switch is one group of optical fiber correlation optoelectronic switch, putty switch is positioned at boundling guide plate 1 side from boundling guide plate 1 bottom 1/3 distance, putty switch comprises the transmitter 3 and receiver 4 that lay respectively at boundling guide plate 1 both sides, the infrared measurement of temperature pick-up unit 5 that an investigative range can cover whole boundling guide plate is installed above boundling guide plate 1.
Putty switch and infrared measurement of temperature pick-up unit 5 all with PLC connection.
One group of optical fiber correlation optoelectronic switch utilizes photoelectric effect, is take light source as medium, when light source by object masks or launch, presence or absence, size and light and shade that radiation, shading cause light income to change carrying out inspected object, and produce the switch module of contact point signal.When bulk polymer buildup is to optoelectronic switch co-altitude, the light between transmitter and receiver is blocked, and light income changes, and optoelectronic switch action the number of delivering letters connect fermium guide head to waste position to PLC allows discharging pump stall.
Putty switch is positioned at the boundling guide plate side from boundling guide plate bottom 1/3 distance, and end of extruded band polymkeric substance adhesive tape out can not the light eye of shading light electric switch again, eliminates one of them misoperation because of rope.Meanwhile, if there is putty phenomenon, optoelectronic switch can detect polymkeric substance putty in advance, and the polymkeric substance of accumulation is greatly reduced.
Temperature probe adopts the IRT series of products of Exergen company of the U.S., and temperature-measuring range is 0 ~ 300 DEG C, the response time 150 milliseconds, distance coefficient 2Omm ~ 1000mm, and precision is ± 1%.This device is installed on the position of about 30 °, boundling guide plate front upper place, and infrared temperature probe is aimed at boundling guide plate and temperature value is converted to current value is sent programmable logic controller (PLC) in real time, and the investigative range of four temperature probes can cover whole boundling guide plate.During putty, temperature is far above the environment temperature (70 ~ 90 DEG C) during normal pelletizing, and when temperature probe detects temperature higher than setting value, PLC program can judge in time, realizes the differentiation of normal pelletizing state and putty state.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
