Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, an embodiment of the present invention is shown: the quick adjusting device for the distance between the rolling cutter heads comprises a cutter shaft 1, connecting sleeves 2 are sleeved at two ends of the cutter shaft 1 in a sliding mode, cutter heads 3 are fixedly sleeved on the outer side walls of the connecting sleeves 2, rotating cavities are arranged at two ends of the cutter shaft 1, threaded rods 4 are connected in the rotating cavities in a rotating mode, one ends of the threaded rods 4 penetrate through the rotating cavities and extend outwards, rotating blocks 5 are fixedly connected at one ends of the threaded rods 4, a moving plate 6 is sleeved on the threaded rods 4 in a threaded mode, a plurality of connecting pieces 7 are fixedly connected to the outer side walls of the moving plate 6, the connecting pieces 7 penetrate through the rotating cavities and are fixedly connected with the inner walls of the connecting sleeves 2, sliding grooves corresponding to the connecting pieces 7 are formed in the outer walls of the cutter shaft 1, and are communicated with the rotating cavities; specifically, a plurality of connecting pieces 7 on the outer wall of the movable disc 6 realize the connection of the connecting sleeve 2 so as to install the cutter disc 3 installed on the connecting sleeve 2, the threaded rod 4 can be driven to rotate in a rotating cavity on the cutter shaft 1 through rotating the rotating block 5 in the actual use process, and the movable disc 6 installed on the threaded rod in the rotating process moves under the meshing effect of the screw thread so as to adjust the position of the cutter disc 3.

In the embodiment, a plurality of anti-skid lines are arranged on the outer side wall of the rotating block 5, and are obliquely arranged, so that the friction force of the rotating block 5 is increased, and the rotating block is convenient to rotate; the outer side wall of the rotating block 5 is fixedly connected with an L-shaped supporting rod 8, one end of the L-shaped supporting rod 8 is slidably inserted with a push rod 9, one end of the push rod 9 is fixedly connected with a limiting block 10, the other end of the push rod 9 is fixedly connected with a fixed block 11, two symmetrically arranged springs 12 are fixedly connected between the fixed block 11 and the L-shaped supporting rod 8, after the proper position is adjusted, the fixed block 11 pushes the push rod to slide on the L-shaped supporting rod 8 under the resilience force of the springs 12 so as to drive the limiting block 10 to move, the limiting block 10 presses against the outer surface of the rotating block 5 so as to realize rotation and fixation, and the phenomenon that the rotating block 5 is mistakenly operated to influence the position of the cutter head 3 is avoided; one side fixedly connected with slipmat 13 that push rod 9 was kept away from to stopper 10, and slipmat 13 material is rubber, the increase and the rotary block 5 between the frictional force, stability is higher.
