Problems solved by technology

However, in this patent, only the injection molding machine is monitored, and the production of the injection molding machine is inseparable from the silo, vacuum pump, suction machine and the above-mentioned finished product assembly line, so the comprehensiveness of the monitoring is not enough and the monitoring is not accurate enough
And in the prior art, there is no detection method for whether the suction machine has completed suction. In order to detect the suction, those skilled in the art can only think of setting a sensor to detect whether the air duct valve is open to judge whether to carry out suction. When the vacuum pump is broken or the pipeline between the silo and the suction machine is blocked, although the air duct valve is opened, no raw material enters the suction machine, so there will be problems of inaccurate monitoring

Embodiment 1

[0029] like figure 1 As shown (the assembly line is not drawn in the figure), the injection molding production line used in the industrial production of injection molding products mainly includes a feed bin 4, a suction machine 1, a vacuum pump 3 for sucking the raw materials of the feed bin 4 into the suction machine 1, The injection molding machine 2 for injection molding and the finished product assembly line that transports the products injected by the injection molding machine 2 to the packaging area, and the finished product assembly line is driven by a motor. The vacuum pump 3 and the silo 4 are respectively connected to the suction machine 1. The discharge end of the suction machine 1 is located above the injection molding machine 2. When the air duct valve between the vacuum pump 3 and the suction machine 1 is opened, the vacuum pump 3 and the suction machine The pipeline of 1 is connected, and the negative pressure generated by the vacuum pump 3 makes the material in...

Embodiment 2

[0044]The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the detection unit is an infrared sensor, the infrared sensor is fixed in the installation hole 10a, and the infrared sensor is connected to the input end of the suction machine controller 9 . When the turning plate 6 is opened, the counterweight 5 rises so that the infrared sensor cannot detect the counterweight 5, and the suction machine controller 9 starts timing after receiving the signal sent by the infrared sensor at this time. When the turning plate 6 opens the suction machine 1 When the time at the discharge end is less than the critical value of the discharge time, it shows that the material in the suction machine 1 is not full and does not meet the normal work requirements. At this time, the suction machine controller 9 sends a fault signal to the processor 8, and the processor 8 will suck the material. The fault information of feeder 1 is se...

Abstract

The invention provides an injection molding production line state monitoring device, and belongs to the technical field of injection molding machine state monitoring. The problems that in the prior art, the monitoring accuracy is low, and the effect is bad are solved. The injection molding production line state monitoring device comprises a display screen, a processor, a material sucking machine controller and a detecting unit. The display screen is connected with the processor, the detecting unit is connected with an input end of the material sucking machine controller, the material sucking machine controller is connected with the processor, and a discharging time critical value is preset in the material sucking machine controller; and after the material sucking machine controller controls a vacuum pump to be disconnected with a material sucking machine, the material sucking machine controller judges whether a turning plate opens a discharging end of the material sucking machine or not according to a signal sent by the detecting unit, when it is judged that the turning plate of the material sucking machine does not open the discharging end of the material sucking machine or the time that the turning plate opens the discharging end of the material sucking machine is shorter than the discharging time critical value, the material sucking machine controller outputs a fault signal to the processor, and the processor controls the display screen to display a fault of the material sucking machine. The injection molding production line state monitoring device can effectively improve the monitoring accuracy.

Description

technical field [0001] The invention belongs to the technical field of state monitoring of injection molding machines, and relates to a state monitoring device of an injection molding production line. Background technique [0002] Injection molding is a method of producing shapes for industrial products, and products usually use rubber injection molding and plastic injection molding. The injection molding production line used in the industrial production of injection molding products mainly includes a silo, a suction machine, a vacuum pump for sucking the raw materials in the silo into the suction machine, an injection molding machine for injection molding, and conveying the products injected by the injection molding machine to the packaging The finished product line in the area is driven by a motor. like figure 1 As shown (the assembly line is not drawn in the figure), the vacuum pump 3 and the feed bin 4 are connected to the suction machine 1 respectively, and the discha...
