[0023] Embodiment 1:

[0024] See also Figure 1-4 , a screw disassembly and clamping device, comprising a support seat 1, the top of the support seat 1 is slidably connected to a support frame 2, the top of the support frame 2 is equipped with a positioning mechanism 3, the positioning mechanism 3 is used to clamp the screw, the bottom end of the support seat 1 is laterally rotatably connected to a transmission shaft 4, one end of the transmission shaft 4 is fixedly connected to a transmission rod 5, the end of the transmission rod 5 away from the transmission shaft 4 is rotatably connected to a linkage rod 6, and the end of the linkage rod 6 away from the transmission rod 5 is rotatably connected to the bottom end of the support frame 2, the other end of the transmission shaft 4 is fixedly connected to a transmission worm gear 7, one side of the support seat 1 is rotatably connected to a central shaft 8, the bottom end of the central shaft 8 is fixedly connected to a transmission worm 9, and the transmission worm 9 is meshingly connected to the transmission worm gear 7;

[0025] It can be understood that the central shaft 8 is rotated to cause the transmission worm 9 to shift the transmission worm wheel 7, thereby driving the transmission shaft 4 to rotate, and the connection between the transmission shaft 4 and the transmission rod 5 is coordinated to make the transmission rod 5 rotate, and the angle between the transmission rod 5 and the linkage rod 6 is changed. Through the change of the angle between the transmission rod 5 and the linkage rod 6, the linkage rod 6 can push the support frame 2 to slide, so that the positioning arc plate 13 reaches the screw position of the screw extruder;

[0026] In more detail, the bottom end of the support base 1 is fixedly connected to a moving base, and moving wheels are arranged at the four end corners of the moving base. The support base 1 can be conveniently moved by the arrangement of the moving wheels.

[0027] In detail, one end of the transmission rod 5 away from the transmission shaft 4 is fixedly connected with a positioning shaft, and the linkage rod 6 is rotatably connected to the outside of the positioning shaft. By setting the positioning shaft, the linkage rod 6 can be stably mounted to ensure the smoothness of the application of the linkage rod 6.

[0028] Furthermore, a transmission frame is fixedly connected to one side of the support seat 1, and the central shaft 8 is vertically rotatably connected to the inside of the transmission frame. By setting the transmission frame, the central shaft 8 can be stably supported to ensure the transmission effect of the transmission worm 9;

[0029] Embodiment 2:

[0030] See also Figure 1-4 , this embodiment provides a technical solution based on the first embodiment: the positioning mechanism 3 includes an assembly frame 10, a linear slide 11, a displacement frame 12, a positioning arc plate 13, a support shaft 14, a linkage plate 15, a linkage groove 16 and a transmission screw 17, the top of the support frame 2 is fixedly connected with the assembly frame 10, the inside of the assembly frame 10 is fixedly connected with the linear slide 11, the two ends of the outer side of the linear slide 11 are slidably connected with the displacement frame 12, the tops of the two displacement frames 12 are fixedly connected with the positioning arc plate 13, the middle part of the inner side of the assembly frame 10 is fixedly connected with the support shaft 14, the outer side of the support shaft 14 is fixedly connected with the linkage plate 15, the two ends of the linkage plate 15 are provided with linkage grooves 16, and the bottom ends of the two displacement frames 12 are respectively slidably connected inside the two linkage grooves 16, one end of the assembly frame 10 is threadedly connected with the transmission screw 17, and the end of the transmission screw 17 located on the inner side of the assembly frame 10 is rotatably connected with one of the displacement frames 12;

[0031] In summary, the transmission screw 17 pushes the displacement frame 12 connected thereto to move. When the displacement frame 12 moves, it can simultaneously push the linkage plate 15, so that it rotates under the support of the support shaft 14. By utilizing the rotation of the linkage plate 15, another displacement frame 12 can be pulled to move, so that the two positioning arc plates 13 are brought closer to each other, thereby forming a clamping of the screw.

[0032] Among them, a rubber pad is fixedly connected to the inner side of the positioning arc plate 13, and an anti-slip pattern is provided on the outer side of the rubber pad. By setting the rubber pad, when the positioning arc plate 13 contacts the screw rod, the screw rod can be protected to avoid damage to the screw rod;

[0033] Here, the bottom ends of the two displacement frames 12 are fixedly connected with guide shafts, and the two displacement frames 12 are respectively connected to the two linkage grooves 16 through the two guide shafts. By utilizing the cooperation of the guide shafts, the displacement frames 12 can be effectively connected to the linkage grooves 16, so that the displacement frames 12 can be moved conveniently.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] When working, first move the support seat 1 to the vicinity of the screw extruder, then rotate the central shaft 8, prompt the transmission worm 9 to turn the transmission worm wheel 7, thereby driving the transmission shaft 4 to rotate, and cooperate with the connection between the transmission shaft 4 and the transmission rod 5, so that the transmission rod 5 rotates, and changes the angle between the transmission rod 5 and the linkage rod 6. Through the change of the angle between the transmission rod 5 and the linkage rod 6, the linkage rod 6 can push the support frame 2 to slide, so that the positioning arc plate 13 reaches the screw position of the screw extruder;

[0036] The transmission screw 17 is rotated, and the transmission screw 17 is connected to the assembly frame 10, so that the transmission screw 17 pushes the displacement frame 12 connected thereto to be displaced. When the displacement frame 12 is displaced, the linkage plate 15 can be pushed at the same time, so that it rotates under the support of the support shaft 14. The rotation of the linkage plate 15 can pull another displacement frame 12 to be displaced, so that the two positioning arc plates 13 are brought close to each other, thereby forming a clamping of the screw, and then the support seat 1 is moved outward to pull the screw out of the screw extruder, so as to form the disassembly of the screw.
