[0024] During operation, in a rubber mixing mill in the above technology, in the process of adjusting the roller spacing, it is necessary to rotate the handlebars on the two sets of spacing boxes respectively. There are scales engraved on the spacing boxes. When rotating the handlebars, it is necessary to ensure that the scale readings on the two sets of spacing boxes are consistent. The adjustment process is relatively cumbersome. Through the structural design of the adjustment mechanism, the function of facilitating the simultaneous adjustment of the handlebars 21 on the spacing boxes 20 is achieved. When the roller spacing on the device body 1 is to be adjusted, the servo motor 32 is first used to drive the screw rod 30 inside the second fixed block 31 to rotate, and the moving block 29 threadedly connected to the screw rod 30 moves on the screw rod 30. The rack 23 is moved so as to move the connecting rods 27 fixed on both sides of the moving block 29. The connecting rods 27 are fixed to the bottom ends of the racks 23, so as to pull out the racks 23 slidably connected to the inside of the first fixed block 26. Since the racks 23 are meshed with the gear ring 22, the racks 23 will drive the gear ring 22 to rotate during the movement. At this time, the rotating handle 21 on the pitch adjustment box 20 will rotate synchronously, so as to achieve the purpose of easy adjustment. Slide blocks 24 are fixed on both sides of the racks 23. The sliding of the slide blocks 24 in the slide grooves 25 ensures that the racks 23 can remain stable during the pulling out process, so as to ensure the normal meshing between the racks 23 and the gear ring 22.

[0025] Furthermore, the rear end of the screw rod 30 is rotatably connected to the inner wall of the second fixed block 31, and the bottom end of the fixed plate 33 is welded and fixed with a reinforcing plate 42, which is welded and fixed to the front end of the device body 1;

[0026] During operation, the fixing plate 33 is fixed on the device body 1 to support and fix the second fixing block 31 , and a reinforcing plate 42 is also fixed on the bottom end of the fixing plate 33 to assist in supporting the fixing plate 33 .

[0027] Furthermore, a connecting block 34 is welded and fixed to the rear end of the rack 23, and a moving wheel 35 is welded and fixed to the bottom end of the connecting block 34. The moving wheel 35 is slidably connected to the long groove 36, and the long groove 36 is opened on the inner wall of the first fixed block 26;

[0028] During operation, through the structural design of the connecting block 34, the moving wheel 35 and the long groove 36, when the rack 23 moves forward, the connecting block 34 will also slide on the long groove 36 through the moving wheel 35, thereby providing support for the rear end of the rack 23, so that the rack 23 can be more stable during the movement.

[0029] Furthermore, a cushion block 37 is glued and fixed on the inner wall of the first fixing block 26, and the cushion block 37 is in contact with the connecting block 34;

[0030] During operation, the cushion block 37 is made of rubber material and is used to cushion the inner walls of the connecting block 34 and the first fixing block 26 to avoid wear caused by the abutment between the inner walls of the connecting block 34 and the first fixing block 26 .

[0031] Furthermore, a material receiving plate 41 is welded and fixed on the top of the second fixing block 31, and the left and right sides of the material receiving plate 41 are fixedly connected to the device body 1;

[0032] During operation, the receiving plate 41 is used to receive the scraps on the device body 1 to prevent the rubber raw materials from falling onto the fixing plate 33 during processing, which makes cleaning inconvenient.

[0033] Furthermore, a plurality of trapezoidal grooves 40 are formed on the fixing plate 33, and a trapezoidal block 38 is slidably connected inside the trapezoidal groove 40, and the trapezoidal block 38 is welded and fixed to the bottom end of the connecting rod 27;

[0034] During operation, the structural design of the trapezoidal block 38 and the trapezoidal groove 40 can improve the stability of the connecting rod 27 during movement, thereby ensuring that the connecting rod 27 moves smoothly and reducing its shaking.

[0035] Working principle: In the prior art, a rubber mixing mill needs to rotate the handlebars on two sets of pitch adjustment boxes respectively during the process of adjusting the roller spacing. The pitch adjustment boxes are engraved with scales. When rotating the handlebars, it is necessary to ensure that the scale readings on the two sets of pitch adjustment boxes are consistent, which is relatively cumbersome during the adjustment process. In this case, a rubber raw material mixing device for aviation tire production with adjustable roller spacing realizes the function of facilitating the simultaneous adjustment of the handlebars 21 on the pitch adjustment box 20 through the structural design of the adjustment mechanism. When the roller spacing on the device body 1 is to be adjusted, the servo motor 32 is first used to drive the screw rod 30 inside the second fixed block 31 to rotate, and the threaded movable member 30 on the screw rod 30 is threadedly connected to the movable member 30. The movable block 29 will move on the screw rod 30, thereby driving the connecting rod 27 fixed on both sides of the movable block 29 to move. The connecting rod 27 is fixed to the bottom end of the rack 23, thereby pulling out the rack 23 slidably connected to the inside of the first fixed block 26. Since the rack 23 and the ring gear 22 are meshed, the rack 23 will drive the ring gear 22 to rotate during the movement. At this time, the rotating handle 21 on the pitch adjustment box 20 will rotate synchronously, so as to achieve the purpose of easy adjustment. Slide blocks 24 are fixed on both sides of the rack 23. The sliding of the slide block 24 in the slide groove 25 ensures that the rack 23 can remain stable during the pulling out process, so as to ensure the normal meshing between the rack 23 and the ring gear 22.

[0036] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
