Principle of the utility model: the second flange can be adjusted up and down, when assembling, loosen the locking bolt, the second flange falls naturally, when the connecting plate of the second flange contacts the silicone strip on the screen machine feeding port, tighten the locking bolt. The utility model eliminates the canvas connection and adopts silicone material as the friction joint surface, which is easy to install and adjust. The silicone has good wear resistance and is durable. Moreover, with long-term operation and use, the joint surface between the silicone strip and the feeding and discharging port will be worn more and more smooth, and there will be no direct contact friction with the silicone strip, so the durability is improved.

[0005] As an improvement, the first flange is formed by bending the feeding channel outward by 90 degrees.

[0006] As an improvement, the second flange is formed by symmetrically arranged side plates and two symmetrically arranged end plates connected end to end, the side plates and the end plates are connected by welding, the long holes are arranged on the side plates, and the side plates and the end plates are both L-shaped.

[0007] As an improvement, a fixing strip is provided on the connecting surface of the third flange, a limiting groove is provided on the fixing strip, and the silicone strip is arranged in the limiting groove.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model eliminates the canvas connection and adopts silicone material as the friction joint surface, which is easy to install and adjust. The silicone has good wear resistance and is durable. Moreover, with long-term operation and use, the joint surface between the silicone strip and the feeding and discharging port will be worn more and more smooth, and there will be no direct contact friction with the silicone strip, so the durability is improved.

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown, a MU screen feeding mechanism comprises a feeding outlet 1 and a screen machine feeding port 2 docking with the feeding outlet 1. The feeding outlet 1 is fixed on the frame, and comprises a feeding channel 11, a first flange 12 arranged at the upper end of the feeding channel 11, and a second flange 13 arranged at the lower end of the feeding channel 11; the first flange 12 is formed by bending the feeding channel 11 outward by 90 degrees, and the first flange 12 and the feeding channel 11 are an integral structure; the second flange 13 comprises a fixing plate 131 and a connecting plate 132, and a connecting block 14 is arranged on the outer side of the feeding channel 11, and a threaded hole is arranged on the connecting block 14, and the fixing plate 131 is provided with a connecting plate 132. The fixed plate 131 is in contact with the outer wall of the feeding channel 11, and a longitudinally arranged elongated hole 16 is provided on the fixed plate 131, and the elongated hole 16 corresponds to the connecting block 14. The fixed plate 131 is fixed to the connecting block 14 by locking bolts 15, so that the second flange 13 is connected to the feeding channel 11; the second flange 13 is surrounded by symmetrically arranged side plates and two symmetrically arranged end plates connected end to end, and the side plates and the end plates are connected by welding, and the elongated hole 16 is arranged on the side plates, and the side plates and the end plates are both L-shaped. A third flange 21 is provided at the upper end of the screening machine feed port 2, and the screening machine feed port 2 is rectangular. Four rectangularly distributed silicone strips 3 are provided on the third flange 21, and a fixing strip 31 is welded on the connecting surface of the third flange 21. A limiting groove is provided on the fixing strip 31, and the silicone strip 3 is arranged in the limiting groove. The silicone strip 3 is installed and positioned by the fixing strip 31, so that it is convenient for disassembly and assembly; the connecting plate 132 of the second flange 13 is in contact with the silicone strip 3, and the wider flange surface prevents gaps from appearing at the joint due to the rotational movement of the screening machine feed port 2.

[0015] Principle of the utility model: the second flange 13 can be adjusted up and down. When assembling, loosen the locking bolt 15, and the second flange 13 falls naturally. When the connecting plate 132 of the second flange 13 contacts the silicone strip 3 on the feed port 2 of the screen machine, tighten the locking bolt 15. The utility model eliminates the canvas connection and uses silicone material as the friction joint surface. It is easy to install and adjust. The silicone has good wear resistance and is durable. Moreover, with long-term operation and use, the joint surface between the silicone strip 3 and the feed and discharge port 1 will be worn more and more smooth, and there will be no direct contact friction with the silicone strip 3, so the durability is improved.
