Product Description
New type of continuous screen changer for foaming products extrusion line
This kind of DHBL series screen changer is designed bases on the plate type hydraulic screen changer, but ,it's a symbol of prograss of the technology. they own the simlar appearance( you can even not see different of their appearance.) But the most difference: you can get from its name. yes . "continuous"
congratulations. continuous, no interrupt the production when we change the screen as the extrusion machine working. also ,this kind of new type continuous screen changer for foaming products extrusion line also equiped with the air venting system, which will help to improve the quality of the product, there will no any bubble in the products.
Look some pictures of this new type continuous screen changer for poaming products extrusion line
Then see how to work of the new type continuous screen changer for foaming products extrusion line.
The basic operation
** Before installation the New type of continuous screen changer for foaming products extrusion line
, the oil pressure of the hydraulic station shall be set to 10 bar
** When installation, the connection flanges should be special sealing, clearance between the locating rings in front and behind should slightly below 0.05-0.10mm, can't be bulged out. Tightly lock the flange bolts symmetrically.
** After installation of the New type of continuous screen changer for foaming products extrusion line
, the sliding plate can be push and pull under the 10bar oil pressure, if can not push and pull freely, it shows that there are deformation problems of the plate, or have different things stuck, we can loose the inlet and outlet flange bolts until sliding freely.
, the sliding plate can be push and pull under the 10bar oil pressure, if can not push and pull freely, it shows that there are deformation problems of the plate, or have different things stuck, we can loose the inlet and outlet flange bolts until sliding freely.
** As required put the filter screen into the slot of the sliding plate, the screen edge and mesh shall not exposed out of the slot. And then push the two screens into the main body of the New type of continuous screen changer for foaming products extrusion line, heating more than 60 minutes up to the operation temperature, then push and pull with 10bar oil pressure, if the sliding can be removable, it shows that the installation is successful.
** The oil pressure shall be adjusted to 4.5-5Mpa, and confirm the two filter screens are in the main body of the screen changer, and then the extrusion machine could be feed material and start operation..
** When the die head is discharging material, push one screen out of the main body about 10-15mm, this time the screen changer is working normally. In the mean time, observe the initial material pressure.
** When the die head is discharging material, push one screen out of the main body about 10-15mm, this time the screen changer is working normally. In the mean time, observe the initial material pressure.
** When the working screen is blocked, the material pressure will be raised 30-40 bar, this time we need to push the exposed screen into the main body, until the blocked screen is pushed out from the other side of the main body, and it will be pulled back to the working position after replacing the fresh screen, and the fresh screen also need to be exposed out 10-15mm.
** After a period of time, the other filter screen will be blocked, pull the fresh screen into the main body until the blocked screen push out totally, and push back after replace the fresh screen, the fresh screen also need to be exposed out 10-15mm
Then we can cyclic operation like this.
** The operation sequence of the New type of continuous screen changer for foaming products extrusion line shall not be violated, otherwise, any damage will not guarantee.
