[0026] A water-cooled twin-screw granulator, such as Figure 1 and Figure 2 As shown, it includes a body 10, and the top surface of the body 10 is equipped with a feeding structure and a granulation structure. The feeding structure includes two auger conveyors, and the granulation structure includes a casing and a granulation plate. The auger conveyor is connected to the casing. The material is conveyed into the casing and is extruded and formed by the granulation plate. The wall of the casing is also equipped with a cutter for cutting the extruded material. The wall of the casing is provided with a push cylinder to push the cutter to reciprocate. The outer wall of the casing is provided with a cover body for cooling the formed material. The cover body has a cavity, and the wall of the cover body is equipped with a water pipe. By connecting the water pipe to tap water, the flowing tap water is used to promote the cooling and forming of the material. This is an existing well-known technology and will not be elaborated here.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, a load-bearing component for support is provided at the bottom of the machine body 10, and the load-bearing component includes a connecting rod 20, an adjusting sleeve 21, a flip body 22, a bottom plate 23 and a cushion block 24. The connecting rod 20 is fixedly connected to the machine body 10, and the adjusting sleeve 21 is threadedly connected to the connecting rod 20. The wall surface of the adjusting sleeve 21 is rotatably connected to a plurality of flip bodies 22. The flip body 22 can flip and protrude the adjusting sleeve 21 to form a lever and push the adjusting sleeve 21 to rotate. The bottom plate 23 is rotatably connected to the adjusting sleeve 21, and a cushion block 24 can be detachably installed at the bottom of the bottom plate 23. The adjusting sleeve 21 forms a cylindrical structure, and the outer wall of the connecting rod 20 is provided with a thread, and the inner wall surface of the adjusting sleeve 21 is provided with a toothed mouth. The connecting rod 20 is threadedly connected to the inner wall surface of the adjusting sleeve 21, and the outer wall surface of the adjusting sleeve 21 is provided with an arc shaped slot, the flip body 22 is located in the slot, the top of the flip body 22 is rotatably connected to the adjusting sleeve 21 through a pin, and the inner wall surface of the adjusting sleeve 21 is also fixedly connected with a permanent magnet, which can absorb the flip body 22 and limit the flip body 22 in the slot. In this solution, by setting the flip body 22, the flip body 22 is flipped out of the slot, and the arc-shaped flip body 22 can serve as a handle, pushing the flip body 22 to drive the adjusting sleeve 21 to rotate and thereby adjust the height of the adjusting sleeve 21 from the ground. The flipped flip body 22 can increase the length of the force arm of the rotating adjusting sleeve 21 to achieve the purpose of labor saving, and the height adjustment of the adjusting sleeve 21 can be achieved without the help of a wrench tool, thereby making the adjustment sleeve 21 more convenient and flexible in supporting and adjusting the machine body 10. Specifically, Figure 6 As shown, the flip body 22 forms an arc-shaped rod structure, and its overall size needs to be smaller than the notch on the wall of the adjusting sleeve 21 to ensure that there is no movement interference. A pin is fixedly connected to the top surface of the flip body 22, and an axial hole is opened on the inner top surface of the adjusting sleeve. The pin is located in the axial hole and is rotatably connected to the adjusting sleeve 21. The flip body 21 rotates around the pin, so that the flip body 22 can be flipped out of the notch and form an arc-shaped blocking arm;

[0028] By providing a rotating bottom plate 23, after the bottom plate 23 contacts the ground, rotating the adjusting sleeve 21 will not cause the bottom plate 23 to rub against the ground, further reducing the resistance of rotating the adjusting sleeve 21. At the same time, the rubber pad 24 can achieve soft contact between the entire machine body 10 and the ground, thereby suppressing resonance and displacement of the machine body 10 caused by hard contact with the bottom surface during the granulation process.

[0029] like Figure 4As shown, the load-bearing component also includes a bottom connecting block 25 and a connecting body 26. The bottom connecting block 25 is fixedly connected to the adjusting sleeve 21, and the connecting body 26 is fixedly connected to the bottom plate 23 and rotatably connected to the bottom connecting block 25. The bottom connecting block 25 forms a metal sphere. A ball socket is provided on the top surface of the connecting body 26. The bottom connecting block 25 fits with the ball socket and rotates in the ball socket. By setting the bottom connecting block 25 and the connecting body 26, the bottom connecting block 25 rotates in the ball socket of the connecting body 26, so that the relative movement of the bottom plate 23 and the adjusting sleeve 21 can be achieved without interference. At the same time, the bottom plate 23 can remain parallel to the ground and support the adjusting sleeve 21. Even if there is a certain slope on the ground at the installation position, the bottom plate 23 can fit the ground to ensure the stability of the support, which is more adaptable and easy to assemble and debug.

[0030] like Figure 4 and Figure 5 As shown, a slot is provided on the bottom surface of the base plate 23, and the pad 24 is interference fit with the slot. The pad 24 is inserted into the slot, and a plurality of anti-skid grooves 30 are evenly provided on the bottom surface of the pad 24. The pad 24 forms a concave and convex contact surface through the anti-skid grooves 30. The anti-skid grooves 30 form rectangular grooves. The anti-skid grooves 30 extend from the side walls of the pad 24 toward the center position. The depth of the anti-skid grooves 30 is less than the thickness of the pad 24. The bottom surface of the pad 24 is provided with a plurality of anti-skid grooves 30 in an annular array. As a supplement to the above scheme, by providing a detachable pad 24, the pad 24 can be inserted into the slot at the bottom of the base plate 23 or pulled out, so that the pad 24 can be disassembled and assembled, which is convenient for replacement and maintenance of the jacking. The pad 24 with the anti-skid grooves 30 makes the contact position of the pad 24 with the ground form an uneven surface, and the pad 24 can be better deformed to ensure full contact with the ground, which has better anti-deviation and elastic support effects on the body 10.

[0031] The working principle of the utility model is as follows: the flip body 22 is flipped out from the slot, and the arc-shaped flip body 22 can serve as a handle. The flip body 22 is pushed to drive the adjusting sleeve 21 to rotate and thus adjust the height of the adjusting sleeve 21 from the ground. The flipped flip body 22 can increase the length of the force arm for rotating the adjusting sleeve 21 to achieve the purpose of saving effort. The bottom connecting block 25 rotates in the ball socket of the connecting body 26, and can realize the relative movement of the bottom plate 23 and the adjusting sleeve 21 without interference. The bottom plate 23 can remain parallel to the ground and support the adjusting sleeve 21. The pad block 24 can be inserted into the slot at the bottom of the bottom plate 23 or pulled out to realize the disassembly and assembly of the pad block 24. The pad block 24 contacts the ground and forms support for the entire body 10.
