AI Technical Summary
In the existing heat insulation strip processing equipment, the extrusion hole is easily blocked by under-hot semi-hot melting material, resulting in the material flow being blocked.
A feed extrusion plate including a plate body and several extrusion units is designed. The extrusion unit consists of convex conductive convex ribs, material grooves on both sides and strip-shaped extrusion holes arranged between phases. The material that is not sufficiently hot melt is directed to the side of the feed groove under the guidance of the conductive convex ribs, away from the convex ribs, and reduces the particle size of the pellet through the extrusion hole.
It effectively avoids clogging of the extrusion holes, ensures smooth flow of materials, and improves the forming quality of the heat insulation strips.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat insulation strip processing equipment and relates to a feed extrusion plate for heat insulation strip processing. Background Art
[0002] When processing the PA66 insulation strip, the mixed powder is first hot-melted, then fed into the die cavity of the extruder, and finally extruded from the die head by pressurized extrusion. The mixed granules after hot-melting need to be fed into the die cavity of the extruder through an extrusion plate. In the prior art, Figure 1 As shown, a plurality of grooves are distributed on the feeding extrusion plate, and extrusion holes are arranged alternately at the bottom of the grooves. The hot-melted material enters the mold cavity of the extrusion device through the extrusion holes. The grooves have the function of gathering the material. However, the existence of the grooves will also cause some semi-hot-melt materials that are not fully hot-melted to gather in the grooves, thereby blocking the extrusion holes. Utility Model Content
[0003] The purpose of the utility model is to provide a feed extrusion plate for processing heat insulation strips in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to avoid clogging of the extrusion holes.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a feed extrusion plate for processing thermal insulation strips, characterized in that it includes a plate body and a plurality of extrusion units located on the plate body, the extrusion unit includes an outwardly protruding material guide rib, each side of the material guide rib has a material groove, and the material guide rib is provided with a plurality of extrusion holes arranged alternately.
[0005] Furthermore, the extrusion hole is in the shape of a strip perpendicular to the material guiding convex rib, the material guiding convex rib and the material trough have a smooth transition, and the material trough and the plate surface where the material trough is located have a smooth transition.
[0006] The advantage of this structure is that compared with the prior art, the material trough still has the function of gathering materials, but it is changed from one to two, and they are symmetrically distributed on both sides of the material guide ribs. The material that is not fully melted can be guided to one side of the material trough by the material guide ribs, and then away from the ribs. In addition, the strip-shaped extrusion holes can reduce the particle size of the pellets passing through the extrusion holes without changing the flow area, making it more difficult for the unmelted pellets to pass through the extrusion holes.

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 2 and Figure 3 As shown, the feed extrusion plate used for processing the thermal insulation strip includes a plate body 1 and a plurality of extrusion units located on the plate body 1, the extrusion unit includes an outwardly protruding material guide rib 2, and the two sides of the material guide rib 2 are respectively provided with a material groove 3, and the material guide rib 2 is provided with a plurality of extrusion holes 4 arranged alternately.
[0013] The extrusion hole 4 is in the shape of a strip perpendicular to the material guiding rib 2 . There is a smooth transition between the material guiding rib 2 and the material trough 3 , and there is a smooth transition between the material trough 3 and the plate surface of the plate body 1 where the material trough 3 is located.
[0014] The advantage of this structure is that compared with the prior art, the material trough 3 still has the function of gathering materials, but is changed from one to two, and is symmetrically distributed on both sides of the material guide rib 2. The material that is not fully melted can be guided to one side of the material trough 3 by the material guide rib 2, and then away from the rib. In addition, the strip-shaped extrusion hole 4 can reduce the particle size of the pellets passing through the extrusion hole 4 without changing the flow area, making it more difficult for the unmelted pellets to pass through the extrusion hole 4.
[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
