Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] When implementing: Figure 1-5 As shown, a detachable granulation template for a plastic extrusion granulator comprises: an inner core 1, a middle ring 101 is arranged on the outer edge of the inner core 1, an outer ring 2 is arranged on the outer edge of the middle ring 101, and a plurality of granulation belts 3 distributed in an annular shape and connected end to end are arranged on one side of the middle ring 101; a mounting structure 4, the mounting structure 4 is arranged inside the granulation belt 3, and the mounting structure 4 is used to facilitate the installation and disassembly of the granulation belt 3; wherein, the mounting structure 4 comprises a plurality of mounting blocks 404 fixedly connected to the inner wall of the middle ring 101, two adjacent granulation belts 3 are symmetrically distributed with the center line of the adjacent mounting blocks 404 as the center, and two groups of threaded holes 411 are opened on the top of the mounting block 404, and the two groups of threaded holes 411 are symmetrically distributed.

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the surface of the granulation belt 3 is provided with two groups of symmetrically distributed mounting grooves 401, the interior of the granulation belt 3 is slidably connected with two symmetrically distributed mounting plates 403, one side of the mounting plate 403 is fixedly connected with two symmetrically distributed connecting strips 402, the two connecting strips 402 are slidably connected to the inner wall of the granulation belt 3, the other side of the mounting plate 403 is fixedly connected with a spring 405, the other end of the spring 405 is fixedly connected to the inner wall of the granulation belt 3, the opposite sides of two adjacent connecting strips 402 are fixedly connected with evenly distributed connecting plates 406, the side of the connecting plate 406 away from the mounting plate 403 is fixedly connected with a limiting block 407, the cross-sectional shape of the limiting block 407 is a right-angled trapezoid, the other end of the limiting block 407 passes through the inside of the adjacent mounting groove 401, the top of the mounting plate 403 is fixedly connected with a shift block, the upper end of the shift block passes through the granulation belt 3;

[0022] The spring 405 is configured to apply pressure to the mounting plate 403, so that it drives the two connecting strips 402 to move away from the spring 405, so that the connecting plate 406 can drive the limit block 407 to always remain inserted into the mounting groove 401. By moving the shift block, the mounting plate 403 can be driven to compress the spring 405 and then drive the limit block 407 to shrink to the inside of the granulation belt 3.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an enlarged portion 409 is provided inside the mounting groove 401, and a limiting hole 410 is provided on the surface of the enlarged portion 409. One end of the limiting block 407 extends to the inside of the adjacent limiting hole 410, and a coaxially arranged threaded rod 408 is fixedly connected to the bottom of the enlarged portion 409, and the lower end of the threaded rod 408 penetrates the granulating belt 3 and is threadedly connected to the inner wall of the adjacent threaded hole 411;

[0024] The setting of the enlarged part 409 is used to facilitate the rotation of the threaded rod 408, and the threaded rod 408 is driven to be inserted into the interior of the installation groove 401 through the enlarged part 409, and the enlarged part 409 is rotated to drive the threaded rod 408 to gradually insert into the interior of the threaded hole 411. In this process, the enlarged part 409 can be assembled and inserted into the interior of the installation groove 401, and the inclined surface of the limit block 407 is squeezed by the bottom of the enlarged part 409 to make it shrink to the interior of the granulation belt 3 until it is installed in place. At this time, the limit block 407 is aligned with the limit hole 410, so that the limit block 407 is driven to reset under the action of the spring 405, and the limit block 407 can be driven to insert into the interior of the limit hole 410. At this time, the position of the enlarged part 409 can be limited, thereby preventing the threaded rod 408 from reversing and avoiding the possibility of falling off during use;

[0025] When disassembling and replacing, the shifting block is pulled to actively drive the mounting plate 403 to compress the spring 405 and simultaneously drive the limiting block 407 to separate from the limiting hole 410, so that the threaded rod 408 can be reversed to disassemble the threaded rod 408 so as to remove the granulating belt 3 for replacement.

[0026] When the utility model is in use, the threaded rod 408 is inserted into the interior of the installation groove 401 through the enlarged portion 409, and the enlarged portion 409 is rotated to drive the threaded rod 408 to gradually insert into the interior of the threaded hole 411. In this process, the enlarged portion 409 can be assembled and inserted into the interior of the installation groove 401, and the inclined surface of the limit block 407 is squeezed by the bottom of the enlarged portion 409 to make it shrink to the interior of the granulation belt 3 until it is installed in place. At this time, the limit block 407 is aligned with the limit hole 410, so that the limit block 407 is driven to reset under the action of the spring 405, and the limit block 407 can be driven to insert into the interior of the limit hole 410. At this time, the position of the enlarged portion 409 can be limited, thereby preventing the threaded rod 408 from reversing and avoiding the possibility of falling off during use. When disassembling and replacing, the mounting plate 403 is actively driven to compress the spring 405 by pulling the shift block, and at the same time drive the limit block 407 to separate from the limit hole 410, so that the threaded rod 408 can be reversed, thereby removing the threaded rod 408 to facilitate the removal of the granulation belt 3 for replacement.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
