Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, the utility model provides a kind of resistance temperature device of the door seal gum cover extruder of refrigerator, packet
The junction of the temperature measuring box 2 for including extruder barrel 1 and being mounted on 1 outer wall of extruder barrel, the temperature measuring box 2 and extruder barrel 1 is set
It is equipped with through-hole 3, horizontal drive plates 4 are provided in the temperature measuring box 2, are provided on two opposite inner walls of the temperature measuring box 2
Limit sliding chutes 5, the limit sliding chutes 5 are located at the top of horizontal drive plates 4, and sliding is provided with limit and slides in the limit sliding chutes 5
Seat 6 is connected with motor fixing seat 7 between limiting slide seat 6 described in two, and the lower end surface of the motor fixing seat 7 is provided with drive
Dynamic motor 8, the output shaft of the driving motor 8 straight down and are connected with pushing plate 9, and the lower end surface of the pushing plate 9 is vertical
It is provided with resistance temperature stick 10, the resistance temperature stick 10 is thread through horizontal drive plates 4, while the resistance temperature
The lower end of stick 10 is extended in extruder barrel 1 by through-hole 3.
In the present invention, resistance temperature stick 10 is the component with material directly contact in extruder barrel 1, in order to keep away
Exempt from the work that resistance temperature stick 10 hampers double screw extruder, the utility model makes following setting: since motor is fixed
The both ends of seat 7 are separately fixed in two limiting slide seats 6, and limiting slide seat 6 is merely able to slide up and down in limit sliding chutes 5, so
Motor fixing seat 7 also can only just be slided up and down and can not be rotated, to limit the driving motor being mounted in motor fixing seat 7
8 moving direction, the resistance temperature stick 10 that just will drive pushing plate 9 when driving motor 8 works and be mounted in pushing plate 9
Rotation, due to being threadedly coupled between resistance temperature stick 10 and horizontal drive plates 4, and horizontal drive plates 4 are kept fixed, so working as
When resistance temperature stick 10 rotates, resistance temperature stick 10 can also move up and down.In the mistake that resistance temperature stick 10 moves up and down
Cheng Zhong also will drive the up and down motion of pushing plate 9, driving motor 8, motor fixing seat 7 and driving motor 8.
It is silent in above description to be, by controlling the rotation direction of driving motor 8, it can be realized and resistance-type is surveyed
The descending operation of warm stick 10.When needing using resistance temperature stick 10 to carry out temperature detection, driving motor 8 rotates forward band
Dynamic resistance temperature stick 10 moves downward, and so that the lower end of resistance temperature stick 10 is inserted into extruder barrel 1 by through-hole 3, to realize
Detection to 1 internal material temperature of extruder barrel.Since the lower end of resistance temperature stick 10 in the utility model is stretched when in use
Enter inside extruder barrel 1, is directly contacted with material in extruder barrel 1, therefore temperature detected is temperature of charge, and
It is not the temperature of 1 inner wall of extruder barrel, therefore detected data are more intuitive accurate.
When using extruder, often first the material in extruder is heated, after material is heated to predetermined temperature
Extrusion operation is carried out again, and the temperature measuring equipment in the present invention works between above-mentioned two process, for whether detecting material
Reach predetermined temperature.Screw rod when due to detection temperature in extruder does not have started rotation, so resistance temperature stick 10 protrudes into
It will not influence screw rod in extruder barrel 1, but when extruder starts extruded material, when screw rod starts turning, be located in extruder barrel 1
Resistance temperature stick 10 just will affect the normal operation of extruder.In order to avoid the generation of above situation, when temperature detection is complete
Cheng Hou, driving motor 8 will rotate backward, to drive resistance temperature stick 10 to rise, until under resistance temperature stick 10
End face is parallel with the inner wall in extruder barrel 1, not only will not influence the rotation of screw rod and the flowing of material in this way, but also can be to avoid
Material flows out extruder barrel 1 from through-hole 3.
As shown in Figure 1, in the present invention, cricoid seal groove 11, institute are provided on the inner wall of the extruder barrel 1
State the outside that seal groove 11 is looped around through-hole 3, be provided with sealing ring 12 in the seal groove 11, the inner wall of the sealing ring 12 with
Resistance temperature stick 10 is in close contact, and 12 lower end surface of sealing ring is flushed with the inner wall of extruder barrel 1, the extruder barrel 1
Outer wall and the temperature measuring box 2 inside and outside wall on be provided with thermal insulation layer 13, the outer surface of the temperature measuring box 2 is provided with heat-insulated
Rack 14 is provided with heat shield 15 on the heat-insulated rack 14, and control chip 16 and display screen are equipped on the heat shield 15
17, the resistance temperature stick 10, control chip 16 and display screen 17 are successively electrical connected.
In the present invention, control chip 16 is using common AT89C51 single-chip microcontroller on the market, no special to want
It asks, resistance temperature stick 10 processes the information detected and passes to control chip 16, and control chip 16 is to information note memory processing
And judgement, and control display screen 17 is shown into temperature registration.Since extruder internal temperature is higher, chip 16 and display are controlled
If screen 17 is mounted on inside extruder or will affect on table wall its service life, therefore control chip 16 and display screen 17 are installed
It is separated in the outside of extruder barrel 1, and by heat-insulated rack 14 and heat shield 15, further avoids high temperature to control chip 16
And the influence of display screen 17.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
