The two groups of limiting sliders are rotatably installed with the middle part of the two groups of rotating drums respectively, which can support the two groups of rotating drums.

[0010] As an optional solution of the technical solution of the present application, a screw hole is opened in the middle of one end of the two groups of slides, and screws are threadedly installed in the two groups of screw holes. The two groups of screws are respectively rotatably installed with the side walls of the two groups of limit sliders, and the two groups of limit sliders can be adjusted.

[0011] As an optional solution of the technical solution of the present application, a gear ring is fixedly installed in the middle of the rotating drum on the other side, and a gear meshing with the gear installed on one side of the gear ring can drive the rotating drum to rotate.

The cooling water will be continuously transported to the inside of the other group of sheeting rollers 11, and finally introduced into the inside of the filter cartridge 23 on the top of the cooling water tank 22. It can not only efficiently cool the two groups of sheeting rollers 11 and cool the thermosetting plastic powder between the two groups of sheeting rollers 11, but also because the filter cartridge 23 is relatively high, when the higher temperature cooling water is introduced into the top of the filter cartridge 23, the high temperature cooling water will move down from the top of the filter cartridge 23 and most of the heat will be taken away by the air, so as to efficiently cool the cooling water and ensure that the device can continuously cool the thermosetting plastic powder.

[0023] In some technical solutions, slideways 3 are fixedly installed on both sides of the conveyor belt 1 through fixing parts, and limiting sliders 31 are slidably installed in the two groups of slides. The two groups of limiting sliders 31 are rotatably installed with the middle parts of the two groups of rotating drums 13 respectively, and can support the two groups of rotating drums 13. Screw holes are opened in the middle parts of one end of the two groups of slideways 3, and screws 32 are threadedly installed in the two groups of screw holes.

[0028] When in use, first introduce the thermosetting plastic powder between the two sets of tableting rollers 11, and then the driving motor 35 drives the gear 34 to rotate. The gear ring 33 meshing with the gear 34 will drive the tableting roller 11 to rotate, and the thermosetting plastic powder between the two sets of tableting rollers 11 will be extruded and tableted. At the same time, the liquid pump 21 inside the driving cooling mechanism will be introduced into the cooling water tank 22 inside the tableting roller 11 on one side, and the two sets of tableting rollers 11 will be connected and installed through the U-shaped tube 24 at one end. The cooling water will be continuously transported to the other set of tableting rollers 11, and finally introduced into the filter cartridge 23 on the top of the cooling water tank 22, which can not only efficiently cool the two sets of tableting rollers 11, but also effectively cool the two sets of tableting rollers 11. 1, and because the filter cartridge 23 is relatively high, when the high-temperature cooling water is introduced into the top of the filter cartridge 23, the high-temperature cooling water will move down from the top of the filter cartridge 23 and most of the heat will be taken away by the air, so as to efficiently cool the cooling water to ensure that the device can continue to cool the thermosetting plastic powder. At the same time, a screw 32 is threadedly installed in the middle of one end of the two sets of slides 3, and the two sets of screws 32 are respectively rotatably installed with the side walls of the two sets of limit sliders 31.
