[0005] The utility model discloses the following technical schemes:

[0006] A high pressure grinding roller pressure grinding gap adjusting structure, including two transmission shafts, each transmission shaft is fixedly sleeved with the eye ring, each eye ring is sleeved with the pressure grinding ring, the eye ring is uniformly provided with a plurality of insertion slots, each insertion slot is slidably connected with the positioning plate, each positioning plate is penetrated and is provided with a plurality of slidingly connected positioning rods, and the both ends of each positioning rod are fixedly connected with the inner wall of the insertion slot.

[0007] Preferably, the fixed ring is screwed with a plurality of bolts, and the fixed ring is fixedly connected with the side wall of the eye ring through the plurality of bolts.

[0008] The utility model has the advantages that: by setting multiple pressure grinding rings with different diameters, the distance between the adjacent two transmission shafts does not need to be adjusted, the labor intensity is reduced, the overall use of the material of the pressure grinding ring is less, the cost is reduced, the diameter of the pressure grinding ring can be controlled during processing, the precision can be effectively guaranteed, repeated adjustment is avoided, time is wasted, and the adjustment efficiency is improved. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 is the schematic diagram of the structure of the utility model;

[0010] Fig. 2 is the front view of the structure of the utility model;

[0011] Fig. 3 is the partial side view of the plugboard in the structure of the utility model.

[0012] In the figure: transmission shaft 1, collar 2, pressure grinding ring 3, insertion slot 4, positioning rod 5, spring 6, positioning plate 7, plug key 8, keyway 9, plugboard 10, fixed ring 11. Specific implementation:

[0013] As Figs. 1 to 3 shown, a high-pressure grinding roller pressure grinding gap adjusting structure, including two transmission shafts 1, each transmission shaft 1 is fixed with a collar 2, each collar 2 is sleeved with a pressure grinding ring 3, a plurality of insertion slots 4 are uniformly arranged on the collar 2, each insertion slot 4 is slidably connected with a positioning plate 7, a plurality of slidingly connected positioning rods 5 are arranged on each positioning plate 7, both ends of each positioning rod 5 are fixedly connected with the inner wall of the insertion slot 4, a spring 6 is sleeved on each positioning rod 5, each positioning plate 7 is fixedly connected with a plug key 8, each plug key 8 penetrates out of the insertion slot 4 and is slidably connected with it, a plurality of keyways 9 are arranged on the inner ring wall of each pressure grinding ring 3, each plug key 8 extends into the corresponding keyway 9 and is slidably connected with it, a slidingly connected plugboard 10 is inserted into each insertion slot 4, one end of each plugboard 10 is inclinedly arranged, one side of each plugboard 10 is abuttingly arranged with the corresponding positioning plate 7, one end of the corresponding plurality of plugboards 10 is fixedly connected with a fixed ring 11, when adjustment work is needed, the fixed ring 11 is pulled away to one side, so that the plurality of plugboards 10 are also pulled out of the corresponding insertion slots 4, so that the positioning plate 7 resets under the elastic force of the spring 6, that is, the plurality of plug keys 8 slide out of the corresponding keyways 9, so that the pressure grinding ring 3 can be smoothly separated from the collar 2 without limiting, then another pressure grinding ring 3 with a matching diameter is replaced (if the interval between the two is increased, a pressure grinding ring 3 with a smaller diameter is selected, and if the gap between the two is reduced, a pressure grinding ring 3 with a larger diameter is selected), then the operation is repeated in turn, so that the corresponding pressure grinding ring 3 is reinstalled, so that normal work can be performed, so that by providing a plurality of pressure grinding rings 3 with different diameters, the distance between the two adjacent transmission shafts 1 does not need to be adjusted, the labor intensity is reduced, the overall use of the pressure grinding ring 3 is less, the cost is reduced, and the diameter of the pressure grinding ring 3 can be controlled during processing, the precision can be effectively guaranteed, thereby avoiding repeated adjustment and wasting time, and improving the adjustment efficiency.

[0014] A plurality of bolts are screwed on the fixing ring 11, and the fixing ring 11 is fixedly connected with the side wall of the sleeve ring 2 through the plurality of bolts, so as to ensure the stability of the plurality of inserting plates 10, thereby ensuring that the pressure grinding ring 3 can normally work.

[0015] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
