If the door panels 2 are larger, two operation handles are vertically and fixedly connected to each door panel 2. Thus, four electric cylinders are needed to be matched, are respectively connected at two ends of two operation handles and synchronously move, so that the function of driving the door plate 2 to move is realized.

In order to solve the problem that a customer needs to replace screens 4 with different specifications according to different working conditions, the screens 4 of the screening machine are provided with various types and specifications in a matching way. For this reason, the application also proposes a variety of screen structures for use with the screening machine.

As shown in fig. 6, one of the screens is a mating screen, which includes a rectangular frame 41, a metal skeleton 42, and a mesh surface 43. The metal skeleton 42 is disposed inside the frame 41 and fixedly connected to the frame 41. The outer parts of the frame 41 and the metal framework 42 are wrapped with polyurethane layers, the net surface 43 is fixedly connected to the frame 41 through bolts (the bolts are also subjected to sealing treatment), and no metal is exposed. The mesh 43 may be made of Polyurethane (PU), polyester (PET) or Polycarbonate (PC). The mesh of the polyester mesh 43 can be made very small, suitable for screening small pieces.

In the other type of the mesh screen, the four sides of the mesh surface 43 are not fixed by bolts, but are provided with folded edges, and are inversely fastened to the frame 41, as compared with the mesh screen 4. When the screen 4 is fixed in the slide rail 1 and the clamping groove 31, the folded edges extend into the slide rail 1 and the clamping groove 31 respectively to be directly pressed. The screen surface 43 can be separated directly by taking out the screen 4 from the frame.

Another screen associated with the screening machine is configured as a split screen, as shown in fig. 7, and includes two rims 41 and a screen surface 43. In this embodiment, the frame 41 of the split screen is lined with a metal skeleton 42, and is wrapped with polyurethane. The mesh surface 43 is made of polyester material, and no metal is exposed. Specifically, one side of one of the frames 41 is L-shaped in cross section, and the horizontal end is disposed outward. One side of the other frame 41 is rectangular in cross section. The rectangular cross-section frame 41 is placed on the horizontal end of the L-shaped cross-section frame 41 and is simultaneously placed outside the vertical end of the L-shaped cross-section frame 41. The two rims 41 are buckled with each other in a concave-convex manner, the net surface 43 is clamped in the middle and tightened, and then the outer periphery of the rims 41 is fixed by countersunk bolts (countersunk bolts are arranged on the surface which is not contacted with the materials). The split screen is not required to be replaced as the integral screen is, and the integral screen is required to be replaced. Only the frame 41 needs to be disassembled, the net surface 43 replaced and reassembled.

A screen mesh for preventing blocking matched with the sieving machine is also designed, as shown in figure 8. Since the condition of blocking the screen 4 is common when screening tiny materials, the materials blocked by the screen 4 need to be cleaned periodically when in use. The anti-blocking screen comprises a frame 41, a screen surface 43, a pocket bottom plate 44 and a plurality of silica gel clean tennis balls 45. The frame 41 is lined with a metal skeleton 42 and is wrapped with polyurethane. The mesh surface 43 is made of polyester material, and no metal is exposed. The mesh surface 43 is fixed to the upper surface of the frame 41. The pocket floor 44 is formed with mesh openings and is fixed to the lower surface of the frame 41. The silica gel clear tennis ball 45 is arranged between the net surface 43 and the pocket bottom plate 44, and is separated by the metal framework 42, so that the silica gel clear tennis ball 45 is uniformly distributed. Wherein the apertures in mesh 43 are smaller than the apertures in pocket floor 44. The diameter of the silica gel cleaning ball 45 is larger than the aperture of the bottom plate 44, so that the silica gel cleaning ball 45 is prevented from falling off. When the anti-blocking screen works, fine materials leak down through the small meshes of the screen surface 43. Due to the larger aperture in the tray 44, material will quickly pass through the entire screen 4. The screening machine continuously vibrates during operation, drives the silica gel cleaning balls 45 to irregularly vibrate in the compartment of each metal framework 42 to strike the upper and lower net surfaces 43, and plays a role in cleaning mesh blocking materials.

The working principle of the application is as follows: the door plate 2 on one side is opened, the screen 4 is pushed to move along the track of the sliding rail 1, the opened door plate 2 is closed again after the screen 4 moves to the working position, and at the moment, two ends of the screen 4 respectively extend into the clamping grooves 31. The door panels 2 on both sides are then pressed inwards by the pressing mechanism. After the door plate 2 is pressed, two ends of the screen 4 are clamped in the clamping grooves 31 on the door plate 2, and the other two ends are limited by the sliding rail 1, so that the screen is firmly fixed in the screening channel. When the screen 4 is taken out, the pressing mechanism is loosened, one side door plate 2 is opened, and the screen 4 is directly pulled out of the sliding rail 1.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model.
