Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse film molds, and specifically refers to an efficient seven-layer greenhouse film mold. 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. Due to the increase in the number of layers, the difference in the diameters of the inner and outer layers is relatively large. When simply using the same number of runners, since the outer diameter is larger and the distance between the runners is farther, it is very easy to appear runner lines and thick-thin channels. With the increase in the number of layers, it becomes more difficult to seal. For the original sealing structure, the method of adding sealing strips around the circumference is adopted. The disadvantage of this method is that it is very easy to leak materials. Each disassembly requires heating for disassembly and assembly, and the sealing strips must be replaced, which increases the maintenance cost. With the increase in the number of layers, the processing space left for the internal cooling holes is very small, resulting in a low passing efficiency of the cooling air.

[0003] Here, in order to solve the above series of problems, we hereby propose an efficient seven-layer greenhouse film mold. 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 an efficient seven-layer greenhouse film mold, which solves the problems of "very easy to appear runner lines and thick-thin channels", "very easy to leak materials" and "resulting in a low passing efficiency of the cooling air".

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

[0006] An efficient seven-layer greenhouse film mold, comprising a distributor, an inner spiral body one, an inner spiral body two, an inner spiral body three, an outer spiral body one, an outer spiral body two, an outer spiral body three, a mold shell, an adjusting ring, a die head and an internal cooling pipe; the distributor is cooperatively installed on the lower side of the mold shell, and a die head is fixedly installed on the top. Inside the annular cavity formed among the distributor, the die head and the mold shell, the inner spiral body two, the inner spiral body three, the outer spiral body one, the outer spiral body two and the outer spiral body three are sequentially stacked from the inside to the outside. An adjusting ring sleeving the outside of the die head is fixedly installed on the top of the mold shell. The internal cooling pipe penetrates and is embedded in the inside of the distributor and is inclined.

[0007] The advantages of the utility model compared with the prior art are as follows:

[0008] 1. After the outer spiral body one, the outer spiral body two and the outer spiral body three of the new type are connected to the jet holes, the end of the jet holes adopts the method of one split into two, increasing the number of runners, making the billet more uniform when exiting the die head, improving the thickness uniformity of the film, and the thickness uniformity can be increased by more than 25%.

[0009] 2. This new type adopts an inclined surface sealing structure, which has better sealing performance and is conducive to disassembly. It does not require heating. By using the designed ejection process hole, it can be ejected, reducing the labor intensity during disassembly.

[0010] 3. This new type increases the diameter of the internal cooling pipe. The internal cooling pipe is installed obliquely inside, improving the passing efficiency of the cooling air, increasing the crystallization speed of the blank, and enhancing the brightness of the film.
