[0044] In this embodiment, the swinging member 2 is swingably arranged on the stand 1, one end of the third pushing member 3 is rotatably arranged on the stand 1, and the other end is connected to the swinging member 2, the swinging member 2 and the stand 1 swing relative to each other, the swinging direction of the swinging member 2 is perpendicular to the stand 1, the extrusion rotating member 4 and the swinging member 2 are rotatably arranged relative to the swinging member 2, when the swinging member 2 is driven to swing by the third pushing member 3, the extrusion rotating member 4 swings synchronously, and at the same time, the extrusion rotating member 4 rotates itself, so that the extrusion rotating member 4 can obtain the effects of swinging and rotating, and perform a multi-directional extrusion effect on the material, making the extrusion effect more sufficient, improving the efficiency of material extrusion dehydration, and enhancing the dehydration effect of the material, and preventing the problem of different moisture content of the material after dehydration in different parts due to insufficient and uneven extrusion.

[0045] A toothed member 5 is provided on the extrusion rotating member 4, and a rack 6 is meshed with the toothed member 5, and the rack 6 is slidably arranged with the swinging member 2. During the reciprocating movement of the rack 6, the toothed member 5 is driven to rotate reciprocatingly, so that the extrusion rotating member 4 periodically switches between two rotation directions, so that the extrusion between the extrusion rotating member 4 and the material is more fully extruded, thereby enhancing the extrusion and dehydration effect of the device on the material and improving the efficiency of the extrusion and dehydration.

[0046] Furthermore, it also includes: a cylinder body 7, which is arranged on the swing member 2, and the cylinder body 7 has a first cavity 701 and a second cavity 702, a first push member 601 and a second push member 602 are respectively arranged at two ends of the rack 6, the first push member 601 is slidably arranged in the first cavity 701, and the second push member 602 is slidably arranged in the second cavity 702.

[0047] In this embodiment, a cylinder body 7 is provided on the swinging member 2, and a first pusher 601 and a second pusher 602 are provided at both ends of the rack 6. The first pusher 601 and the second pusher 602 form a sealed first cavity 701 and a second cavity 702 with the cylinder body 7. The first cavity 701 and the second cavity 702 are both hydraulic sealed cavities. During operation, the hydraulic station injects pressure and releases pressure into the two sealed cavities in turn, so that the first pusher 601 and the second pusher 602 push the rack 6 to move in turn, drive the toothed member 5 to reciprocate, and make the extrusion rotating member 4 reciprocate in two directions. The rack 6 has a stable reciprocating motion with sufficient driving force to drive the stable rotation of the toothed member 5, thereby improving the operating stability of the device and enhancing the use effect of the device.

[0048] Furthermore, the extrusion rotating member 4 is slidably arranged relative to the swinging member 2 , and the extrusion rotating member 4 is slidably arranged relative to the gear member 5 .

[0049] In this embodiment, there is relative sliding between the extrusion rotating member 4 and the swinging member 2. In addition to the overall movement of the device itself, the extrusion rotating member 4 also has a small relative sliding with the swinging member 2, and the material is repeatedly extruded within a small range, thereby improving the efficiency of extrusion dehydration, making the extrusion between the extrusion rotating member 4 and the material more complete, and enhancing the extrusion dehydration effect of the device on the material.

[0050] Furthermore, the toothed member 5 has a sliding groove 501 , and the extrusion rotating member 4 has a guiding portion 401 , and the guiding portion 401 is slidably disposed in the sliding groove 501 .

[0051] In this embodiment, when the extrusion rotating member 4 and the swinging member 2 slide against each other, the tooth member 5 arranged on the extrusion rotating member 4 slides synchronously. In this scheme, the tooth member 5 has a sliding groove 501, and the extrusion member guide part 401 slides in the sliding groove 501, so that the extrusion rotation process of the extrusion rotating member 4 is smoother, and the slippage damage caused by the movement of the internal structure is reduced.

[0052] Furthermore, the cylinder body 7 also has an axial cavity 703 , and the extrusion rotating member 4 also has a piston portion 402 , and the piston portion 402 is slidably disposed in the axial cavity 703 .

[0053] In this embodiment, the piston portion 402 of the extrusion rotating member 4 is slidably disposed in the axial cavity 703 of the cylinder body 7, and the piston portion 402 is hydraulically pushed to drive the extrusion rotating member 4 to reciprocate in the cylinder body 7, so that the extrusion driving member produces a small reciprocating motion, thereby enhancing the extrusion and dehydration effect of the device on the material. The use of the piston portion 402 to drive makes the reciprocating motion effect of the extrusion rotating member 4 in the axial cavity 703 more stable.

[0054] Furthermore, the extruded rotating member 4 is rotatably and slidably arranged in the shaft cavity 703, and also includes: a guide sleeve 8, which is arranged in the shaft cavity 703, a linear bearing mounting sleeve 9, which is arranged in the guide sleeve 8, and a linear bearing 10, which is arranged between the linear bearing mounting sleeve 9 and the extruded rotating member 4.

[0055] In this embodiment, a guide sleeve 8 is arranged in the shaft cavity 703, a linear bearing mounting sleeve 9 is arranged in the guide sleeve 8, and a linear bearing 10 is arranged between the linear bearing mounting sleeve 9 and the extrusion rotating member 4. The extrusion rotating member 4 has both rotation and sliding movement modes in the shaft cavity 703. Direct relative sliding or relative rotation with the inner wall of the shaft cavity 703 will cause great wear to the inner wall of the shaft cavity 703 and the extrusion rotating member 4. In this solution, a linear bearing 10 is arranged between the inner wall of the shaft cavity 703 and the extrusion rotating member 4, which can make the extrusion rotating member 4 have a more stable reciprocating rotation and reciprocating sliding effect inside.

[0056] Furthermore, it also includes: a frame 11 and a slide 12 , wherein the slide 12 is slidably arranged on the frame 11 , and the platform 1 is slidably arranged on the slide 12 .

[0057] In this embodiment, the device is further provided with a frame 11, a slide 12 slides relative to the frame 11, and the platform 1 slides relative to the slide 12, and the relative sliding trajectory of the slide 12 and the frame 11 is perpendicular to the relative sliding trajectory of the slide 12 and the frame 11. The two vertical trajectories can provide multiple degrees of freedom in a plane for the platform 1 and the extrusion rotating member 4 arranged on the platform 1, so that the extrusion rotating member 4 can extrude and knead the material from different positions, thereby improving the efficiency of extrusion dehydration, making the extrusion between the extrusion rotating member 4 and the material more sufficient, and enhancing the extrusion dehydration effect of the device on the material.

[0058] Furthermore, the first driving member 13 is disposed on the frame 11 to drive the slide 12 to slide on the frame 11 , and the second driving member 14 is disposed on the slide 12 to make the extrusion rotating member 4 slide relative to the frame 1 .

[0059] In this embodiment, the first driving member 13 is arranged on the frame 11, driving the slide 12 to slide on the frame 11, and the second driving member 14 is arranged on the slide 12, so that the extrusion rotating member 4 and the table 1 slide relative to each other. The first driving member 13 and the second driving member 14 are both controlled by motors. The first driving member 13 and the second driving member 14 respectively control the two directions of freedom of the table 1, so that the movement of the extrusion rotating member 4 is more stable, and the change of the material extrusion position can also be more accurately controlled.

[0060] Furthermore, the third pusher 3 also includes: a screw nut 301, which is hinged on the swing member 2, a screw 302, which is threadedly connected to the screw nut 301, and a motor 303, which is hinged to the stand 1 to drive the screw 302 to rotate.

[0061] In this embodiment, the third pushing member 3 also includes a screw rod 302, which is threadedly matched with a screw nut 301 arranged on the swinging member 2. When the motor 303 drives the screw rod 302 to rotate, the screw rod 302 arranged at one end of the swinging member 2 will approach or move away from the direction of the third pushing member 3 under the action of the screw nut 301. The forward and reverse rotation of the motor 303 can realize the reciprocating swing of the swinging member 2 relative to the stand 1, thereby realizing the swinging extrusion of the extrusion rotating member 4 relative to the material, squeezing and kneading the material from more directions, making the material dehydrated more fully and the extrusion efficiency higher.

[0062] Furthermore, it also includes: a magnetostrictive displacement sensor 16, which is disposed in the shaft cavity 703, the first cavity 701, and the second cavity 702. In this embodiment, the magnetostrictive displacement sensor 16 is disposed in the shaft cavity 703, the first cavity 701, and the second cavity 702, and can detect the sliding amplitude of the extrusion rotating member 4 in the shaft cavity 703, as well as the first pusher 601 and the second pusher 602, so as to more accurately control the movement of the extrusion rotating member 4, improve the accuracy of the operation of the device, and greatly reduce the probability of internal collision damage during the operation of the device.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
