[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] A split screen, such as Figure 1 and Figure 2 As shown, it includes a split side net 1 and a bottom net 2, and two side nets 1 are symmetrically arranged. The side nets 1 are located on both sides of the bottom net 2. Dense sieve holes 3 are evenly distributed on the side nets 1 and the bottom net 2. Symmetrical mounting holes 4 are opened on the side net 1. The mounting holes 4 are waist-shaped holes and the length is set vertically. The waist-shaped mounting holes 4 can achieve fine-tuning of the installation position. In actual use, screws or bolts are inserted into the mounting holes 4 to fix them to the required components, so that the side net 1 can be independently detachable. The bottom of the bottom net 2 has a mounting frame 5 fixed thereto, and the mounting frame 5 is located below the bottom net 2, and shafts for installation are provided on both sides of the mounting frame 5, which are installed with the help of the shafts. The mounting frame 5 is located at the bottom of the bottom net 2 to protect and safeguard it.

[0028] like Figure 1 and Figure 2 As shown, the shaft body includes a hinge shaft 6 on one side and a clamping shaft 7 on the other side. The end of the clamping shaft 7 has a clamping end 8. During the actual installation process, one side of the bottom net 2 can be hinged and installed with the help of the hinge shaft 6, and then the other end is clamped and fixed by the clamping shaft 7. When the bottom net 2 needs to be opened, it is only necessary to release the clamping shaft 7, and the bottom net 2 can be flipped down around the hinge shaft 6 to achieve an open state, which is convenient for cleaning and internal inspection. In actual use, the hinge shaft 6 and other components are also detachably connected, so that when the bottom net 2 is seriously blocked or damaged, it can be disassembled independently to achieve the purpose of replacement, and the replacement operation is simple and convenient.

[0029] By separating the side net 1 and the bottom net 2 into independent and detachable parts, they can be disassembled and cleaned independently according to the different blockage conditions of each part in actual use. When damaged, they can be replaced independently, avoiding the need to clean or replace the entire screen every time, reducing unnecessary waste.

[0030] like Figure 1 and Figure 2As shown, the bottom of the bottom mesh 2 is an arc surface that matches the curvature of the shaping roller. In actual use, the shaping roller will be installed inside the screen to shape and break up the material. The bottom of the bottom mesh 2 is an arc surface that can better fit the shaping roller, ensuring that the material on the screen that has not passed through the sieve hole 3 can be well contacted by the shaping roller to achieve further breakup, thereby achieving better shaping and breaking up effect.

[0031] like Figure 1 and Figure 2 As shown, the shape of the sieve hole 3 in this embodiment is a regular hexagon. Since the material is usually oblate during the granulation process, the regular hexagonal shape of the sieve hole 3 can effectively reduce the phenomenon of material clogging at the sieve hole 3. Moreover, the regular hexagonal shape of the sieve hole 3 has a higher area utilization rate. More sieve holes 3 can be distributed under the same area to improve the screening efficiency.

[0032] Example 2

[0033] A screen assembly, such as Figure 3 and Figure 4 As shown, it includes a bearing seat 9 and embodiment 1, two bearing seats 9 are symmetrically arranged, the bearing seats 9 are arranged vertically to the side nets 1, and the two sides of the bearing seat 9 are respectively fixed to the two side nets 1 by screws or bolts. A mounting block 10 for hinged installation of the hinge shaft 6 is provided on one side of the bearing seat 9, and a clamping plate 11 for clamping the clamping shaft 7 is provided on the other side of the bearing seat 9. The mounting block 10 and the clamping plate 11 can be detachably connected to the bearing seat 9 by fasteners, which is convenient for installation and replacement. The fasteners can be screws or rivets, etc.

[0034] like Figure 3 and Figure 4 As shown, a concave rotation groove 12 is provided on the top of one side of the mounting block 10, and the rotation groove 12 is adapted to the hinge shaft 6. During actual installation, the hinge shaft 6 is placed in the rotation groove 12 to realize the flipping of the bottom net 2. When disassembly is required, it is only necessary to lift it up to realize the disassembly of the hinge shaft 6 from the rotation groove 12, thereby realizing the disassembly of the bottom net 2. The operation is simple, convenient and fast, and the overall structure is simple.

[0035] like Figure 3 and Figure 4The cam 13 is provided with a hook groove 14 on the side of the card plate 11 for clamping the clamping end 8 of the clamping shaft 7. The clamping shaft 7 on the bottom net 2 is hooked with the help of the hook groove 14 to prevent it from falling, so as to achieve the installation and fixation of the bottom net 2. When disassembling, it is only necessary to rotate the card plate 11 so that the clamping shaft 7 is disengaged from the hook groove 14. The bottom net 2 can be rotated and turned down around the hinge shaft 6 under the action of its own gravity to achieve the opening of the bottom net 2. At this time, the bottom net 2 can be cleaned or the interior can be inspected. When the bottom net 2 needs to be disassembled as a whole, it is only necessary to further lift the bottom net 2 so that the hinge shaft 6 is disengaged from the rotating groove 12. The installation of the bottom net 2 is the same, and the operation is simple and convenient. In addition, a handheld plate 15 perpendicular to it is extended on the card plate 11, and the handheld plate 15 is convenient for personnel to hold and rotate the card plate 11.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
