What is EPS ?

Expanded Polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls. It is this closed cellular construction that gives EPS its remarkable characteristics. EPS is produced in a wide range of densities providing a varying range of physical properties. These are matched to the various applications where the material is used to optimise its performance and strength.

Automatic Vacuum Packaging Machine Frame System1

In the design and manufacture, the framework system is the largest and most complex part.

(1) Rack is the support around the molding machine, connecting parts, including four guide posts and other fixed parts, its steel design and manufacturing accuracy, determines the machine’s life and product accuracy.

(2) mold frame machine mold forming mechanism by the dynamic mode, fixed-mode composition. In general, the dynamic mold frame to install the punch, fixed mold frame to install the die. Punch on the relatively simple, there is no attachment, die on the need to install the material gun and mandrel. There are exhaust valve on the mold frame, behind the three support plate, the support plate should be evenly distributed.

(3) Condenser Products Before vacuum cooling, the steam needs to be cooled by the condenser. Condenser for the tube-type, is an indirect cooling, steam, cooling water is not direct contact, steam walk tube, cooling water jacket. If the steam is cooled by cooling water, it is a direct contact. Condenser is good or bad, affecting the effect of vacuum and cooling speed.

How to maintain the molding machine?

We all know that the construction of the machine is more complex, how to maintain the machine, I believe that many friends should not be very understanding, then, I told you how to maintain into models.

Forming machine maintenance in several ways, the first is the maintenance of the circuit, we usually use the molding machine in the process to always pay attention to the circuit board clean, remember to clean up the strength of the box time dust, try to keep the box dry, So as to avoid damp; the second is the maintenance of oil, the need to regularly check the various parts of the oil circuit there is no oil spill, if any time to deal with, to prevent the piston rod scratches and oil quality deterioration; the third is mechanical maintenance, Check the machine drive parts have no wear, check the butter mouth is not blocked, pay attention to the amount of butter, add butter.

There is also the molding machine hydraulic oil needs to be replaced once a year, to clean up the oil phase of the sludge, clean up the water cooler in time to prevent the rise in oil temperature caused by accelerated aging.

EPS recycling machine

EPS recycling system consists of Crushing machine, De-duster and Mixer Etc. The crushing machine smashes wasted EPS products or EPS scraps into granule, then through de-duster to sieve and remove the dust. After Sieving and de-dusting, the recycling material is mixed with virgin material According to definite proportion, and to be used in both Shape and Block Molding Machine.

Machine Features:

1,Twin shaft crushing blades, this machine adopts manual feeding, the material will be crushed by the twin shaft blades and conveyed to the barrel of the main machine through the screen.

2,The screw of the main machine can convey the heating the material to melt condition ,then extrude them and hydraulic blade cut them to pieces for easy storage and transportation.

3,The shape of the products can be designed according to customers’ requirement.

Working Principle:

The twin shaft crushing blades are two parallel blades shaft with different rotation direction , each blade shaft has 18 blades and driven by the gear box to crush material that will be conveyed to the barrel through the screen. The material will be sent by the high speed rotary screw to the heating barrel. Then they will be melted under high temperature extruded to expected sharps.

Automatic thermoforming machine control system requirements 3

Stretch. The drawing process is carried out by a simple hydraulic system so that the heated soft sheet forms a more regular shape for easy vacuum forming. The hydraulic system includes a three-phase asynchronous motor, three proximity switches and one on-delay relay.

Forming. The sheet is formed by evacuating the softened sheet by means of a vacuum in the mold to form a desired regular shape on the mold. In this system, the vacuum pump is activated by the solenoid valve.

Pinch feet. Fitting action depends on the processing needs of the product, the same is through the solenoid valve to brake, as a vacuum forming the auxiliary action, is conducive to the formation of regular shape of the product.

Punching. After the mold is processed into the desired shape, the product is cut from the sheet by the punching and shearing process, and then the stack is packed. Similarly, the punching and shearing action is controlled by two servo motors. It is necessary to set the speed, steering and operation time of the motor in the program.

Stacking. The stacking action is done by the servo motor with the photoelectric switch and counter. Stacked lifts to punch out the product according to set the number of stacked up to facilitate the packaging. Before the counter reaches the set count value, the elevator moves according to the stroke set by the program. When the count value is reached, the lift will be pushed according to the setting of the other stroke.

Pull the arm action. The function of the arm mechanism is to send the stacked product to the conveyor chain. The arm motor is a single-phase asynchronous motor whose start and stop is controlled by the proximity switch. When the stacking elevator is pushing out the product, the proximity switch is activated to start the arm motor, and the motor reversal and reset are controlled by the other proximity switches.

Delivery. Transmission is done through the chain rail mechanism, the transmission motor is a single-phase asynchronous motor, by the proximity switch control its action.

Received. The control of the receiving action is similar to that of the feeding part, and it is also judged by the proximity switch whether it is necessary to start and stop the motor so that the scrap can be rolled up. The receiving motor is a three-phase asynchronous motor.
