in order to solve the technical problem, the utility model discloses a realize through following technical scheme:
the utility model provides a production of plastics master batch is with changing filter screen device, trades net ware, first fuse-element pipeline and second fuse-element pipeline including two, trade the net ware and include the main part, the main part top is equipped with the support, the support is equipped with the cylinder, makeup and back makeup before the main part is equipped with, preceding makeup is equipped with the fuse-element entry, back makeup is equipped with the fuse-element export, be equipped with the picture peg that reciprocates by the cylinder drive between preceding makeup and the back makeup, the picture peg is equipped with the filter screen, first fuse-element pipeline intercommunication first branch pipe and second branch pipe, the fuse-element entry of makeup before first branch pipe and the second branch pipe are connected one respectively to the other end of first branch pipe and second branch pipe, second fuse-element pipeline intercommunication third branch pipe and fourth branch pipe, the fuse-element export of makeup after a trade net ware is connected respectively to the third branch.
Further, the picture peg is provided with a groove for installing the filter screen.
Further, the groove is circular.
Further, the support includes the backup pad, the backup pad is worn to establish the cylinder, the backup pad is equipped with four bracing pieces, per two the bracing piece install respectively in preceding makeup and back makeup.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses when can realizing the filter screen and changing, the melt flow is undulant little in the production process, basically has no influence to production stability, has improved production efficiency and product quality effectively.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in figures 1 and 2, the utility model relates to a plastic master batch production is with changing filter screen device mainly comprises front and back Y type fuse-element pipeline 1, two screen changers 2. A plastic melt extruded by double screws is divided into a left strand and a right strand through a Y-shaped melt pipeline, the left strand and the right strand respectively enter a screen changer 2, the Y-shaped melt pipeline comprises a first melt pipeline 3 and a first branch pipe 15 and a second branch pipe 16, the screen changer 2 comprises a main body 5, a support 6 is arranged above the main body 5, the support 6 is provided with an air cylinder 7, the main body 5 is provided with a front jointed board 8 and a rear jointed board 9, the front jointed board 8 and the rear jointed board 9 are fixedly connected or welded through bolts, the front jointed board 8 is provided with a melt inlet 10, the first branch pipe 15 and the second branch pipe 16 are respectively communicated with melt inlets 10 of two screen changers 2, the rear jointed board 9 is provided with a melt outlet 11, the front and the rear of the screen changer 2 are connected with a melt pipeline, an inserting plate 12 driven by the air cylinder 7 to move up and down is arranged in the middle of the screen changer 2. The melt after passing through the screen changer 2 is synthesized into a melt by a Y-shaped melt pipeline, and the melt enters the next working procedure, wherein the Y-shaped melt pipeline comprises a second melt pipeline 4 and a third branch pipe 17 and a fourth branch pipe 18 which are communicated, and the third branch pipe 17 and the fourth branch pipe 18 are respectively communicated with the melt outlets 11 of the two screen changers 2. When the front-back pressure difference of the filter screen 13 reaches a certain value and the filter screen 13 needs to be replaced, the filter screen 13 of one of the screen changers 2 is replaced firstly, and at the moment, because the filter screen of the other screen changer 2 still works, the pressure fluctuation of the melt is not large, and the production stability is not influenced.
Wherein, support 6 includes backup pad 19, and cylinder 7 is worn to establish by the backup pad, and backup pad 19 is equipped with four bracing pieces 20, and every two bracing pieces 20 are installed respectively in preceding makeup 8 and back makeup 9.
Because the device adopts the double screen changers 2, when the filter screen of one screen changer 2 is changed, the flow of the melt is not interrupted, and only the flow proportion distributed in the two filter chambers is different, so the flow basically does not change obviously, thereby effectively improving the production stability when the screen is changed and reducing the waste.
Finally, it should be noted that: although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements and the like can be made in the technical solutions of the foregoing embodiments or in some technical features of the foregoing embodiments, but all modifications, equivalents, improvements and the like within the spirit and principle of the present invention are intended to be included in the scope of the present invention.
