Abstract
The utility model relates to an injection molding machine hopper underfeeding alarm, which is mainly composed of a pressing sheet, a guide rod, a spring and an inductor. The injection molding machine hopper underfeeding alarm is characterized in that the pressing sheet is mounted on the charging barrel at a position which is one third of the distance from a discharge port; the pressing sheet is connected with the guide rod; the spring is fixed on the segment of the guide rod extending out of the charging barrel; the inductor is fixed at the end of the guide rod extending out of the charging barrel. When the material in the barrel is higher than the one third position, the material presses the pressing sheet, and the spring is in a tension state and presses the alarm, and at that time an inductor switch is not turned on and does not alarm. When the material in the barrel is lower than the one third position, the pressure on the pressing sheet is reduced, the spring bounces, and the inductor switch is turned on and alarms. When insufficient material is supplied to an injection molding machine hopper, an alarm is generated to inform a person in advance, so that equipment stop is avoided, and production loss is reduced.
Description
Technical field
The utility model relates to a kind of plastic bottle transfusion injection machine hopper and lacks material additional alarm equipment.
Background technology
Plastic infusion bottle all is to be made through the high temperature bottle blowing by plastic bottle preform at present; in the process of preparation bottle embryo; every injection machine feed all is to control the travel switch suction by the beautiful spotflower herb of suction feeder in process of production; the time and the material travel switch also occurs in the barrel not having and can not get closed signal, cause to lack material and shut down.On the large industrialized streamline, a certain procedure hesitation all can influence the operation of whole streamline, for enterprise causes very big loss.The present invention improves the injection machine hopper construction, can give warning in advance under scarce material situation, avoids harmful effect.
The utility model content
The purpose of this utility model is to send warning when injection machine hopper material is under-supply, informs in advance, does not cause equipment downtime.
In order to solve the deficiency that existing hopper exists, the technical scheme that the present invention realizes is:
At barrel a compressing tablet is installed apart from discharging opening 1/3rd places, compressing tablet links to each other with guide rod, guide rod stretches out outer one section of tube and goes up spring is fixedly arranged, guide rod stretches out the outer end of tube fixedly inductor, and when material in the tube during greater than 1/3rd height, material is oppressed compressing tablet, spring is in tension, the compressing alarm, this moment, the inductor switch was not closed, did not report to the police; When material in the tube less than 1/3rd whens height, compressing tablet pressure reduces, spring is upspring, the inductor switch closure gives the alarm.
The utility model has solved because material in the injection machine hopper is difficult for checking constantly, lacks the difficult problem that material is stopped work and cause, for production has reduced trouble and loss.
Description of drawings
Fig. 1 is utility model suspension ring schematic appearance;
Among the figure: 1-charging aperture, 2-barrel, 3-discharging opening, 4-compressing tablet movable end, 5-compressing tablet, 6-guide rod, 7-spring, 8-inductor
The specific embodiment
Embodiment 1, as shown in drawings,
Material enters in the barrel (2) from charging aperture (1), be discharging opening (3) in the bottom of barrel (2), at barrel (2) compressing tablet (5) is installed apart from discharging opening (3) 1/3rd places, compressing tablet (5) is fixed on the interior compressing tablet movable end (4) of barrel (2), compressing tablet (5) links to each other with guide rod (6), guide rod (6) stretches out outer one section of barrel (2) and goes up spring (7) is fixedly arranged, guide rod (6) stretches out the outer end of barrel (2) fixedly inductor (8), when material in the tube greater than 1/3rd whens height, material compressing compressing tablet, spring is in tension, the compressing alarm, this moment, alarm switch was not closed, did not report to the police; When material in the tube less than 1/3rd whens height, compressing tablet pressure reduces, spring is upspring, the alarm switch closure gives the alarm.
Claims (1)
1. an injection machine hopper lacks the material alarm, it is characterized in that: mainly be made up of compressing tablet, guide rod, spring, inductor; At barrel a compressing tablet is installed apart from discharging opening 1/3rd places, compressing tablet links to each other with guide rod, guide rod stretches out outer one section of tube and goes up spring is fixedly arranged, guide rod stretches out the outer end of tube fixedly inductor, and when material in the tube during greater than 1/3rd height, material is oppressed compressing tablet, spring is in tension, the compressing alarm, this moment, the inductor switch was not closed, did not report to the police; When material in the tube less than 1/3rd whens height, compressing tablet pressure reduces, spring is upspring, the inductor switch closure gives the alarm.
