Former eps foam plate density automatic weighing system, suction are claimed by special vacuum cylinder suction by constant volume measuring cup
Weight calculates corresponding density, and entire sampler and Weighing mechanism are complicated, to operating environment requirements height, at high cost, reliability
Low, in addition existing molding machine same specification eps foam plate density variation range after molding is ± 0.5KG/m3, is completely dependent on pre-
The hair stage debugs the personal experience of work to control, and density variation is larger to make the of low quality of plate.
Summary of the invention
In order to solve deficiency in the prior art, the application provides a kind of eps foam plate weighing formation system, structure letter
It is single, it is at low cost, same specification eps foam plate density variation range can be substantially reduced, improves the quality of cystosepiment, and provide simultaneously
Based on the weighing forming method of eps foam plate weighing formation system, its technical solution is as follows:
A kind of eps foam plate weighing formation system, including feeding motor, weighing sensor, material storing box, molding machine, hydraulic cylinder
And PLC controller, the feeding motor are connected to material storing box by feeding tube, material storing box upper end is equipped with weighing sensor, lower end
It is provided with pan feeding valve, the pan feeding valve is connected to molding machine inside cavity by feeding pipe, is provided in the die cavity up and down
Die cavity active module, die cavity active module bottom connect hydraulic cylinder telescopic end, the feeding motor, weighing sensor, pan feeding
Valve and hydraulic cylinder are electrically connected PLC controller.
Further, up and down stroke size of the die cavity active module in die cavity is 5cm.
A kind of eps foam plate weighing forming method, includes the following steps:
A, feeding motor starts, and conveys EPS particle, the EPS of weighing sensor real-time detection investment toward material storing box by feeding tube
Particle weight is simultaneously fed back to PLC controller；
B, PLC controller controls whether feeding motor continues to feed according to the EPS particle weight of the investment of feedback, if reaching setting
Weight, pan feeding valve, which is opened, all send the EPS particle in material storing box into the intracavitary progress step c of molding machine die, stores up after feeding
Hopper feeds again, if not reaching setting weight continues step a;
C, die cavity active module is pushed up 5cm under the control of PLC controller and slowly squeezes EPS particle by hydraulic cylinder, and
Steam is passed through to be allowed to form；
D, after the eps foam board finished product after to be formed takes out, hydraulic cylinder drives die cavity active module to reset downwards；
E, die cavity active module resets repeat the above steps after the completion a, b, c, d.
According to above-mentioned technical proposal, this system first investment storage before putting into molding machine die cavity by the EPS particle after sending out in advance
Hopper is weighed, and stops pan feeding after reaching setting weight, and the EPS particle of fixed weight is put into die cavity every time, and rear mold
The die cavity active module of intracavitary setting is mobile to be squeezed closely, then is passed through steam and is allowed to form, and each piece of eps foam plate density is reached
Almost the same, density variation can be to the effect within every cube of 0.1KG, compared with prior art, the present invention structure is simple, cost
It is low, it also has the advantage that
1, increase a weighing sensor, to detect the EPS particulate material weight for preparing investment, and feed back and arrive PLC controller,
To control whether feeding motor continues pan feeding；
2, a material storing box is increased, to store the EPS particulate material for preparing investment molding machine；
3, pan feeding valve is increased, after PLC controller, which receives weighing sensor, reaches the signal of setting weight, opens pan feeding
Valve, will be in the EPS particulate material investment molding machine of material storing box；
4, increase a die cavity active module, die cavity active module is controlled by hydraulic cylinder and is moved up and down；Molding machine pan feeding
Terminate, die cavity active module rises 5cm, and molding machine inside cavity is having a size of required trimmed size at this time, when eps foam board finished product takes
After out, which resets, and it is 5cm big than eps foam board finished product to be sized width for die cavity when reset.
