Abstract
The utility model relates to an automatic alarm device of a material position for an extruding machine hopper, which relates to the field of automatic control. The hopper is connected with a negative pressure fan through an air suction pipe and a filter screen, and is connected with a raw material box through a material suction pipe. The automatic alarm device has the characteristics that a photoelectric sensor is arranged on the side wall of the hopper, the photoelectric sensor is connected with a controller, and the controller is connected with an alarm device. Since the photoelectric sensor is arranged on the side wall of the hopper, when the material changes into nothing, the light-transmitting amount changes, and the change is translated into an electric signal change and is transmitted to the controller, according to the designed value, the controller judges whether the material exists, and controls the warner to work. When the material position in the hopper of the extruding machine reaches the alarming position, the warner automatically alarms, reminding the staff of taking measures to avoid a quality accident.
Description
Technical field:
The utility model relates to automation field, especially extruder hopper material level autoalarm.
Background technology:
The roof packing box is used for packing and does not contain the vapour beverage, is used for the packing of cold storing and fresh-keeping milk more, and its shelf-life is 4～7 days, this packaged form of the many employings of the preserving milk that provides in the modern supermarket.Packing box used wrapping paper in roof is two-sided aluminum foil composite paper, and in the production technology of this paper, the PE complex technique is absolutely necessary.Common material-uploading style is that when the needs material loading, negative-pressure air fan starts, and through air intake duct and screen pack, makes and forms negative pressure in the hopper; Meanwhile, the suction tube that is connected with hopper and former hopper sucks the PE raw material in the former hopper in the hopper, is the extruder feed.Since the continuity of producing, the insufficient raw material in former hopper, and when perhaps the problem of Yin Teding caused material loading to stop, the staff often was difficult to find at once, and therefore the production line of paper causes the product quality defects still in ceaselessly running, causes damage.
The utility model content:
In order to address the above problem, the utility model provides extruder hopper material level autoalarm, when material level in the extruder hopper reaches the warning position, reports to the police automatically, reminds the staff to take measures.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: extruder hopper material level autoalarm; Comprise the extruder hopper, described hopper is connected negative-pressure air fan through air intake duct with screen pack, connects former hopper through suction tube; It is characterized in that; On the sidewall of hopper, be provided with photoelectric sensor, described photoelectric sensor connects a controller, and described controller connects a warning device.
Described warning device is that sound or light are reported to the police.
Described photoelectric sensor adjustable positions.
The beneficial effect of the utility model is: owing on the sidewall of hopper, be provided with photoelectric sensor, when material was from having to do not having, light transmission capacity changed; This change transitions is that controller is passed in the variation of the signal of telecommunication; Controller is judged having or not of material according to setting value, and the control alarm work.When material level in the extruder hopper reaches the warning position, report to the police automatically, remind the staff to take measures, avoid occurring quality accident.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Among the figure, 1 extruder, 2 hoppers, 3 warning devices, 4 photoelectric sensors, 5 air intake ducts, 6 negative-pressure air fans, 7 suction tubes, 8 former hoppers.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, through the specific embodiment, the utility model is set forth in detail below.
As shown in fig. 1; Extruder hopper material level autoalarm comprises extruder hopper 2, and described hopper is connected negative-pressure air fan 6 through air intake duct 5 with screen pack; Connect former hopper 8. when the needs material loading through suction tube 7; Negative-pressure air fan 6 starts, and through air intake duct 5 and screen pack, makes and forms negative pressure in the hopper; Meanwhile, the suction tube that is connected with hopper and former hopper sucks the PE raw material in the former hopper in the hopper, is extruder 1 feed.
On the sidewall of hopper 2, be provided with photoelectric sensor 4, described photoelectric sensor 4 connects a controller, and described controller connects a warning device 3.When material was from having to do not having, light transmission capacity also changed, and was this change transitions that controller is passed in the variation of the signal of telecommunication, and controller is judged having or not of material according to setting value, and 3 work of control warning device.
Described warning device is that sound or light are reported to the police.Described photoelectric sensor adjustable positions is to regulate controlling level.
Claims (3)
1. extruder hopper material level autoalarm; Comprise the extruder hopper, described hopper is connected negative-pressure air fan through air intake duct with screen pack, connects former hopper through suction tube; It is characterized in that; On the sidewall of hopper, be provided with photoelectric sensor, described photoelectric sensor connects a controller, and described controller connects a warning device.
2. extruder hopper material level autoalarm according to claim 1 is characterized in that, described warning device is that sound or light are reported to the police.
