Description

Improved gradient color splitter

technical field

The utility model relates to a fluid distributor, in particular to a fluid distributor used in the production of plastic sheets and film extrusion production lines and installed between an extruder and an extrusion die head.

Background technique

Early products such as plastic sheets and films were realized through in-mold co-extrusion dies. The dies were large in size, high in manufacturing cost and limited in lack of replacement product types. Just be difficult to realize through specific adjustment or simple replacement of some parts.

Utility model content

The purpose of the utility model is to provide an improved gradient color dispenser, which can control the position of the color bars through the confluence mandrel, and the dispenser has a simple structure and low cost.

Above-mentioned object realizes through following technical scheme:

The improved gradient color distributor includes the organic body, the confluence mandrel and the flow channel between the two. The body is divided into the feed end body, the main body and the discharge connecting plate. There are feed ports for the main machine and auxiliary machines on the top, and it is characterized in that: the auxiliary machine flow channels and the main machine flow channels of different materials in the middle and on both sides are designed on the confluent mandrel, and the auxiliary machine flow channels are 1 or 1 More than one, the host flow channel is divided into two upper and lower flow channels after entering the body at the feed end, and converges on the discharge side of the confluence mandrel in the way of covering the confluence mandrel.

As for the confluence mandrel, the flow channel of the main machine is designed on the surface of the confluence mandrel in such a way as to cover the confluence mandrel, and the auxiliary machine flow channel passes through the confluence mandrel and exits from the other side.

The confluent mandrel is set in the main body through the sealing gasket and the cover plate.

The installation direction of the confluent mandrel can be the same as the feeding direction of the auxiliary machine, or can be perpendicular to the feeding direction of the auxiliary machine.

By adopting the distributor with the above structure, products with different color strip positions can be obtained by setting the positions of the main flow channel and the auxiliary machine flow channel in the confluent mandrel, and the distributor has simple structure, convenient adjustment and operation, and low cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-4, the improved gradient color distributor includes an organic body, which is composed of a feed end body 1, a main body 2 and a discharge connecting plate 3, wherein the confluent mandrel 4 passes through the sealing gasket and the cover plate 41 In the main body 2 in the middle, the body 1 at the feed end has a main machine feed port 11 and an auxiliary machine feed port 12, and the auxiliary machine flow channel and the main machine flow channel of different raw materials in the middle and on both sides are designed on the confluent mandrel 4. Road, the auxiliary machine flow channel 121 is connected with the auxiliary machine feed port 12, the main machine flow channel 111 is connected with the main machine feed port 11, the auxiliary machine flow channel 121 is at any position of the confluence mandrel 4, and the auxiliary machine flow channel 121 is 1 One or more, the host runner 111 is divided into two upper and lower runners after entering the feed end body 1, the host runner 111 is designed on the surface of the confluence mandrel 4 in a way that covers the confluence mandrel 4, and the two hosts The runners merge at the discharge side of the confluence mandrel, and the auxiliary machine runner 121 passes through the axis of the confluence mandrel 4 and passes out from the other side. Wherein, the installation direction of the confluence mandrel 4 may be the same as the direction of the auxiliary machine feed port 12, or may be perpendicular to the direction of the auxiliary machine feed port 12.

Products with different color stripe positions can be obtained by setting the positions of the main flow channel 111 and the auxiliary machine flow channel 121 in the confluence mandrel 4, and the distributor has simple structure, convenient adjustment and operation, and low cost.
