Description

An EPS foam board weighing molding system

technical field

The utility model relates to the field of EPS foam board production equipment, in particular to an EPS foam board weighing molding system.

Background technique

EPS foam board, also known as polystyrene foam board, EPS board, is a white object that is heated and formed in a mold after heating and pre-expanding by expandable polystyrene beads containing a volatile liquid foaming agent. The structural characteristics of fine closed cells have the advantages of light weight, shock resistance, drop resistance, heat insulation, sound absorption, heat preservation, self-extinguishing, environmental protection, anti-aging, low cost, etc. It is mainly used for building walls, roof insulation, composite board insulation, cold storage , air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc.

The original EPS foam board density automatic weighing system, the material is sucked through a special vacuum cylinder, weighed by a fixed volume measuring cup, and the corresponding density is calculated. The entire sampling device and weighing mechanism are complex, requiring high requirements for the working environment and high cost. , low reliability. In addition, the density deviation range of the EPS foam board of the same specification after molding by the existing molding machine is ±0.5KG/m³, which is completely controlled by the personal experience of the debugger in the pre-release stage. not tall.

Utility model content

In order to solve the deficiencies in the prior art, this application provides an EPS foam board weighing and molding system, which has a simple structure and low cost, can greatly reduce the density deviation range of the same specification EPS foam board, and improve the quality of the foam board. Its technical solution as follows:

An EPS foam board weighing molding system, comprising a feeding motor, a load cell, a storage box, a molding machine, a hydraulic cylinder and a PLC controller, the feeding motor is connected to the storage box through a feeding pipe, and the storage box The upper end is equipped with a weighing sensor, and the lower end is provided with a feeding valve. The feeding valve is connected to the inner mold cavity of the molding machine through the feeding pipe. A mold cavity movable module that moves up and down is arranged in the mold cavity, and the bottom of the mold cavity movable module The telescopic end of the hydraulic cylinder is connected, and the feeding motor, weighing sensor, feed valve and hydraulic cylinder are all electrically connected to the PLC controller.

Further, the movable stroke of the mold cavity movable module in the mold cavity is 5 cm.

A working principle of EPS foam board weighing molding, the specific steps are as follows:

a. The feeding motor is started, and the EPS particles are conveyed to the storage box through the feeding pipe, and the weighing sensor detects the weight of the EPS particles in real time and feeds back to the PLC controller;

b. The PLC controller controls whether the feeding motor continues to feed according to the weight of the input EPS particles fed back. If the set weight is reached, the feeding valve opens and all the EPS particles in the storage box are sent into the mold cavity of the molding machine for step c. , after the feeding is finished, refill the storage box, if the set weight is not reached, continue to step a;

c. Under the control of the PLC controller, the hydraulic cylinder pushes the mold cavity movable module up 5cm to slowly extrude the EPS particles, and injects steam to form them;

d. After the finished EPS foam board to be formed is taken out, the hydraulic cylinder drives the movable module of the mold cavity to reset downward;

e. Repeat steps a, b, c, and d above after the mold cavity movable module is reset.

According to the above technical scheme, this system puts the pre-released EPS particles into the storage box for weighing before putting them into the mold cavity of the molding machine, stops feeding after reaching the set weight, and puts EPS particles of a fixed weight into the mold cavity every time , and then the mold cavity movable module set in the mold cavity moves and squeezes tightly, and then steam is introduced to form it, so that the density of each EPS foam board is basically the same, and the density deviation can be within 0.1KG per cubic meter. Compared with the prior art, the structure is simple and the cost is low, and also has the following advantages:

1. Add a weighing sensor to detect the weight of the EPS granule raw material to be put in, and feed it back to the PLC controller to control whether the feeding motor continues to feed;

2. A storage box is added to store the EPS granule raw materials ready to be put into the molding machine;

3. The feeding valve is added. When the PLC controller receives the signal from the weighing sensor to reach the set weight, it opens the feeding valve and puts the EPS granule raw material in the storage box into the molding machine;

4. Add a mold cavity movable module, and control the mold cavity movable module to move up and down through the hydraulic cylinder; after the feeding of the molding machine is completed, the mold cavity movable module rises by 5cm. At this time, the mold cavity size in the molding machine is the required finished product specification. When EPS After the finished foam board is taken out, the movable module of the mold cavity is reset, and when reset, the mold cavity is 5cm larger than the set size and width of the finished EPS foam board.
