Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse film processing, in particular to a seven-layer greenhouse film die distributor without dead angles. Background Art

[0002] With the development of agricultural films, the functional requirements are getting higher and higher. The properties of various masterbatches vary greatly, which puts higher requirements on the equipment. The original three-layer or five-layer die distributors adopt a side-feed coating structure with a large number of dead angles. When changing raw materials and colors, it takes more than 1 hour to complete the replacement, wasting a large amount of raw materials. Moreover, its side-feed structure is prone to uneven distribution, resulting in large deviations in the flow path lines and the thickness of the film.

[0003] Here, to eliminate the above problems, we hereby propose a seven-layer greenhouse film die distributor without dead angles. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a seven-layer greenhouse film die distributor without dead angles, which has no dead angles when shunting (feeding) materials during use.

[0005] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0006] A seven-layer greenhouse film die distributor without dead angles includes an inner spiral body. The bottom opening end of the inner spiral body is fixed with an outer flange one. In the inner cavity of the inner spiral body, an outer flange two, an outer flange three, a middle flange, an inner flange one, an inner flange two, and an inner flange three are sequentially arranged from the opening end inward. Seven groups of jet holes are sequentially arranged in the inner spiral body from top to bottom. Each group of jet holes corresponds to the outer flange one, the outer flange two, the outer flange three, the middle flange, the inner flange one, the inner flange two, and the inner flange three from bottom to top. An inlet pipe communicating with each jet hole is arranged on the outer flange one.

[0007] Each group of jet holes is evenly provided with a plurality of jet holes along the horizontal circumferential direction, and the intersection of the plurality of jet holes is located on the central axis of the inner spiral body.

[0008] The advantages of the utility model compared with the prior art are as follows:

[0009] The utility model adopts a central feeding and jet hole distribution method, reducing the dead angles formed by the flow path and the wall surface, reducing the material change and color change time, reducing the waste of raw materials caused by color change or product change. The color change and material change time can be reduced by 80%, improving the finished product rate; at the same time, due to the reduction of dead angles, the decomposition of raw materials (reduction of paste) caused by the stagnation or deceleration of raw material flow in the dead angle position is avoided, improving the finished product rate, reducing the number of times of cleaning the die, improving the utilization efficiency of the equipment, and reducing the labor intensity of workers.
