[0021] Example 1

[0022] Reference Figure 1-6 A vacuum extruder comprises a bottom plate 1, the top of the bottom plate 1 is fixedly connected to an extruder body 2, the top of the extruder body 2 is fixedly connected to a feed hopper 3, one side of the extruder body 2 is fixedly connected to a motor 4, the other side of the extruder body 2 is fixedly connected to a cylinder 5, the cylinder 5 is provided with multiple groups and is distributed parallel to one side of the extruder body 2, one side of the cylinder 5 is fixedly connected to a first mounting plate 6, one side of the first mounting plate 6 is provided with an arc groove 9, the outer wall of the first mounting plate 6 is provided with a limiting groove 10, the inner wall of the limiting groove 10 is slidably connected to a slider 1 1. A ring 12 is fixed to one side of the slider 11, and the ring 12 is sleeved on the outer wall of the cylinder 5. The slider 11 is provided with multiple groups and is distributed circumferentially on one side of the ring 12. The inner wall of the ring 12 is provided with a thread. Another group of the cylinder 5 is fixed to one side of the second mounting plate 7, and the second mounting plate 7 is fixed to one side of the arc plate 8. The surface of the arc plate 8 is provided with a thread. The arc plate 8 is inserted into the inner wall of the arc groove 9. Multiple groups of the arc plates 8 are provided on the inner wall of the ring 12, and the outer wall of the cylinder 5 is provided with a fixing component for fixing the ring 12.

[0023] In order to solve the problem that the discharging cylinder is inconvenient to be disassembled and assembled according to processing requirements, when the length of the discharging cylinder needs to be increased, one group of cylinders 5 can be placed on one side of the other group of cylinders 5, and the first mounting plate 6 set on one group of cylinders 5 is aligned with the second mounting plate 7 on the other group of cylinders 5, and the arc plate 8 on the first mounting plate 6 can be inserted into the arc groove 9 on the second mounting plate 7, and multiple groups of arc plates 8 can be inserted into the arc groove 9 at the same time, and then the ring 12 is rotated. When the ring 12 rotates, it will drive the slider 11 on one side to slide in the limit groove 10, and the rotation trajectory of the ring 12 can be limited when the ring 12 rotates. Since the outer wall of the arc plate 8 and the inner wall of the ring 12 are provided with Thread, so when the ring 12 rotates, it can drive multiple groups of arc plates 8 to move to one side, and drive the first mounting plate 6 on one side and a group of cylinders 5 to move to one side, until the first mounting plate 6 is attached to one side of the second mounting plate 7, and the ring 12 is tightened, so that the two groups of cylinders 5 can be tightly installed, and the position of the ring 12 can be fixed by the fixing component. When the length of the multiple groups of cylinders 5 after combination meets the processing requirements, the raw materials can be added to the feed hopper 3, and then the raw materials can be crushed and stirred by the extruder body 2. After the raw materials are mixed to a suitable state, the raw materials can be extruded into a green body with high density, good mechanical strength, no internal stress and smooth surface through the discharge barrel.

[0024] Reference Figure 4 The fixing assembly includes a mounting box 14, which is fixed to the top of the cylinder 5. A spring 15 is fixed to the inner wall of the mounting box 14, and a disc 16 is fixed to one side of the spring 15. A plug 17 is fixed to the center of the disc 16. One end of the plug 17 extends out of the inner wall of the mounting box 14, and a slide rod 18 is fixed to the top of the plug 17. The top of the slide rod 18 extends out of the inner wall of the mounting box 14. A fixing hole 13 is opened on the side of the ring 12 away from the slider 11. The fixing holes 13 are provided in multiple groups and are distributed circumferentially on one side of the ring 12. One end of the plug 17 is inserted into the inner wall of the fixing hole 13.

[0025] When the ring 12 needs to be rotated, the slide bar 18 can be pulled, and the insertion rod 17 can be pulled to one side by the slide bar 18. When the insertion rod 17 moves, the disc 16 will move together. The spring 15 can be squeezed by the movement of the disc 16 until one side of the insertion rod 17 moves out of the circular hole, thereby releasing the fixation of the ring 12, causing the ring 12 to rotate and prompting the two sets of cylinders 5 to be installed. When the ring 12 is rotated to the appropriate position, the slide bar 18 can be released. After the slide bar 18 is released, the spring 15 will lose its tension and reset. When the spring 15 resets, it will push the disc 16 and the insertion rod 17 on one side to reset to one side. When the insertion rod 17 resets to one side, it will be inserted into the fixing hole 13 on one side of the ring 12, so that the position of the ring 12 can be fixed, so that the first mounting plate 6 can be tightly mounted on one side of the second mounting plate 7.

[0026] Reference Figure 4 A pull block 19 is fixed to the top end of the slide rod 18, and the pull block 19 is arc-shaped.

[0027] By arranging the arc-shaped pull block 19 at the top end of the slide rod 18 , when the movable rod needs to be pulled, the arc-shaped pull block 19 can be used to pull the rod to one side.

[0028] Reference Figure 6 The outer wall of the ring 12 is fixed with a protrusion 20 , and the shape of the protrusion 20 is trapezoidal. There are multiple groups of protrusions 20 and they are distributed in a circle on the outer wall of the ring 12 .

[0029] By providing multiple sets of trapezoidal protrusions 20 on the outer wall of the ring 12 , when the ring 12 needs to be rotated, the multiple sets of trapezoidal protrusions 20 can be used to increase the friction force of the outer wall of the ring 12 , which is beneficial for the operator to rotate the ring 12 .

[0030] Reference Figure 4 The inner wall of the second mounting plate 7 is fixed with an inclined plate 21, the cross section of the inclined plate 21 is a right triangle, and the inner wall of the first mounting plate 6 is provided with an inclined groove, and the inclined plate 21 is inserted into the inner wall of the inclined groove.

[0031] By arranging the inclined plate 21 on the inner wall of the second mounting plate 7, the inclined plate 21 can be installed into the inclined groove when the second mounting plate 7 is installed on one side of the first mounting plate 6, which can help improve the fit between the first mounting plate 6 and the second mounting plate 7.

[0032] Working principle: In order to solve the problem that the discharge cylinder is inconvenient to disassemble and assemble according to processing requirements, when the length of the discharge cylinder needs to be increased, one group of cylinders 5 can be placed on one side of the other group of cylinders 5, and the first mounting plate 6 set on one group of cylinders 5 is aligned with the second mounting plate 7 on the other group of cylinders 5, and the arc plate 8 on the first mounting plate 6 can be inserted into the arc groove 9 on the second mounting plate 7, and multiple groups of arc plates 8 can be inserted into the arc groove 9 at the same time. By pulling the pull block 19, the pull block 19 can drive the sliding rod 18 and the insertion rod 17 to one side. When the insertion rod 17 moves, it will drive the disc 16 to move together, which can be achieved through The spring 15 is squeezed by moving the disc 16 until one side of the insertion rod 17 moves out of the circular hole, thereby releasing the fixation of the circular ring 12. Subsequently, the circular ring 12 is rotated, and the friction force of the outer wall of the circular ring 12 is increased by multiple sets of trapezoidal protrusions 20, which is convenient for the operator to rotate the circular ring 12. When the circular ring 12 rotates, it drives the slider 11 on one side to slide in the limiting groove 10, and can limit the rotation trajectory of the circular ring 12 when the circular ring 12 rotates. Since the outer wall of the arc plate 8 and the inner wall of the circular ring 12 are both provided with threads, when the circular ring 12 rotates, it can drive multiple sets of arc plates 8 to move to one side. And drive the first mounting plate 6 on one side and a group of cylinders 5 to move to one side until the first mounting plate 6 is attached to one side of the second mounting plate 7, and the ring 12 is tightened, so that the two groups of cylinders 5 can be tightly installed. By arranging the inclined plate 21 on the inner wall of the second mounting plate 7, the inclined plate 21 can be installed in the inclined groove when the second mounting plate 7 is installed on one side of the first mounting plate 6, thereby facilitating the improvement of the fit between the first mounting plate 6 and the second mounting plate 7. Then release the slide rod 18. After the slide rod 18 is released, the spring 15 loses its tension and resets. When the spring 15 resets, it pushes the disc 16 and The insertion rod 17 is reset to one side. When the insertion rod 17 is reset to one side, it will be inserted into the fixing hole 13 on one side of the ring 12, so that the position of the ring 12 can be fixed, so that the first mounting plate 6 is tightly mounted on one side of the second mounting plate 7. When the length of the multiple groups of cylinders 5 after combination meets the processing requirements, the raw materials can be added to the feed hopper 3, and then the raw materials can be crushed and stirred by the extruder body 2. When the raw materials are mixed to a suitable state, the raw materials can be extruded into a green body with high density, good mechanical strength, no internal stress and smooth surface through the discharge barrel, thereby completing the extrusion process of the raw materials.
