Category Tag

Our tandem extruder, an integral component of the EPE Foam Sheet Extrusion Line consists of :

A primary extruder that melts and intensively mixes EPE with a blowing gas and other additives.

A secondary extruder optimizes cooling and forwards the melt to the foaming die enabling proper and maximum output.

A unique screw provides intensive mixing and enables the production of quality foam sheets with any cell size, density, flexibility, and surface texture.

The video above will give you a simple understanding of how the machine works.
Then it begins with a detailed explanation of the machine:

Extruder

The extruder for the polyethylene foam sheet machine consists of a Motor, Gearbox, Loader, Hopper, Screw, Heating Unit, Cooling System, Hydraulic Filter, and Die head.

According to the requirements of product width, thickness, and output, the model of the machine have the difference of 105/120/135/150/180/200/220/250. The naming of the model is based on the diameter of the screw barrel.

To further elaborate on this, take a look at the pictures below (This photo is EPE machine Model JG-FPM105).

1. Motor

The motor is the source of power for the EPE machine. It provides the kinetic energy of the entire production process. TONGJIA uses Siemens brand motor. As a world-renowned manufacturer, Siemens has branches and after-sales services in most countries and regions around the world. The fault can be resolved quickly, even if the engineer of TONGJIA cannot reach the customer’s factory within 72 hours after the fault occurs due to visa issues, the after-sales department of Siemens can also handle the fault well.

2. Gearbox

The function of the gearbox is to convert the fast rotating power provided by the motor into a more powerful torque force to drive the entire screw to rotate. TONGJIA chose the GUOMAO brand. As the largest gearbox brand manufacturer in China, the GUOMAO brand provides solutions for more than 90% of China’s plastic machines. TONGJIA has used GUOMAO brand gearbox for nearly 20 years, and the failure rate is less than 2%.

3. Auto Feeder
Auto Feeder

Even with the smallest model of EPE, the height of the hopper from the ground is still more than 1700mm. Obviously, it is not appropriate to use workers to carry the plastic materials into the hopper, so it is better to use a feeder. The feeder can transport plastic raw materials into the hopper by the force of negative pressure.

4. Hopper

The hopper is mainly used for the temporary storage of plastic raw materials. According to the difference of EPE models, the volume of the hopper will also change. You can pay a certain fee to upgrade to stainless steel, but the material of the hopper will not affect the quality of the final product, it just looks better.

5. Screw

The screw is equivalent to the heart of EPE. The main function of the screw is to cooperate with the heating system and cooling system to transform the plastic raw materials from granular to a molten state, and to better mix and disperse with other auxiliary materials to ensure that each bubble in the EPE sheet is uniform, So as to control the density and reduce the production cost of users. TONGJIA uses high-strength materials to ensure long-term production even if users use completely recycled plastic materials.

6. Heating Unit

The heating system uses electric heating to heat the screw so that the plastic material in the screw quickly reaches a molten state. It has to be said that due to the Voltage stability of different users, the parts in this system are easily damaged. No matter what brand or material is selected, the result will not change. The only good news is that TONGJIA provides enough Heating spareparts are packaged together with the machine when shipped.

7. Cooling System

In fact, if we want to process plastic raw materials into what we want, we need to control the temperature of the plastic raw materials, so that the plastic raw materials inside the screw can be fully mixed and quickly reduced to the correct temperature range. There are currently two cooling methods, one is external water cooling, and the other is internal oil cooling. For EPE products, external water cooling is sufficient. Internal oil cooling will not improve the performance of the final product much, but it will also greatly increase the price of the machine. By the way, we recommend that users who use water cooling should establish a closed water system in their own factories and add soft water treatment because the only failure of the external water cooling system is that the pipes are blocked due to scale.

8. Hydraulic Filter

The hydraulic filter is an important device to reduce the user’s production cost. If you have used a drinking water purifier, you will quickly understand that this device filters the impurities in the recycled plastic raw materials to make the low-priced recycled raw materials close to new The performance of raw materials, even these recycled raw materials are dirty. Must say it again, TONGJIA’s EPE machine can better use 100% plastic recycling materials, not only because of the hydraulic filter, but also because of the special treatment and design decisions made on the screw.

9. Die Head

Come to the last device of the extruder, the Die head. We want to control the thickness of the EPE sheet and the width of a certain range needs to be controlled by it. We can understand that it is the brain part of this machine. Adjust the bolts on the top to control the outlet size of the plastic material that is already at the optimal temperature. If the outlet range is increased, the thickness of the EPE sheet will become thicker. If the outlet range is reduced, the EPE sheet thickness will become thinner. If you want to be simpler, we also have automatic head adjustment devices for areas where workers high salary. Of course, you need to pay for them.

The part of the extruder is finished, then we will explain the middle and end of the machine.

10. Formed Size unit

Maybe when we talked about the machine die head, we also mentioned that the machine die head can adjust the width of the EPE sheet, but only a little bit. The device that can really determine the width of the EPE is the Formed Size unit​. The perimeter of this unit is the width of the EPE sheet. When the EPE product comes out from the position of the machine die head, it is in a cylindrical shape. Then, after magnification, cooling, and molding, the Formed Size unit has a cutting unit to cut the circle The tube becomes a sheet.

11. Flattening platform

Well, must have to admit that this shelf is very simple, and it is indeed the least valuable part of the whole machine, but it is still a necessary part. These shelves allow the sheet to be flattened and then naturally cooled down in contact with air. If you want to replace these racks with stainless steel for a more beautiful appearance.

12. Traction Devices

If you just want to push the EPE sheet to the winding unit by the pressure of the screw. It is impossible, so you need a traction device to achieve a pulling force to pull the EPE sheet to the back. It must be noted that the responsible factory must install a static elimination system on this device, which is absolutely the MOST IMPORTANT for the user and his workers! ! !

13. Winding Unit

At the end of the machine, that is, the winding unit, TONGJIA adopts the double-station winding unit, which can reduce the waste of time and allow the machine to produce products with maximum efficiency. By the way, the wearing part of this unit is the airbag in the reeling rod, which needs to be replaced every 18 months, because the material of the airbag will age after oxidation and high frequency and high pressure.
