The beneficial effects are that:

1. Compared with the prior art, the device has the advantages that the product to be sheared is fixed, the pouring channels on two sides of the product are sheared through the rotary motion and the sliding motion of the rotary shearing device, meanwhile, two groups of shearing structures which are vertically symmetrical are arranged in the device, the pouring channels on the left side and the right side can be sheared only by rotating the device once, the time for changing the positions of the device is greatly reduced, the shearing process time of a single product is shortened, the production efficiency is improved, and the manufacturing cost of the product is further reduced.

2. In the utility model, the pushing mechanism is arranged between the two groups of shearing structures, and the sheared runner is hung on the shearing structure because of no support, so that the shearing structure is prevented from being blocked when the other runner is sheared, the pushing assembly is pushed by the second driving unit to push the sheared runner away from the shearing structure, and the sheared runner falls out of the rotary shearing pushing device, thereby ensuring the continuity of the shearing process and the production and processing progress of the whole production line.

Further, the rotary driving structure comprises a mounting table and a first driving cylinder, a central transmission shaft is rotatably arranged on the mounting table, one end of the central transmission shaft is fixedly connected with the sliding driving structure, the other end of the central transmission shaft is connected with a rotary push plate, and a piston rod of the first driving cylinder is rotatably connected with the rotary push plate.

Through the rotation angle of the limiting rotation push plate, excessive rotation is prevented, and unnecessary resources and time are wasted.

Further, the mount table is equipped with annular guard plate, is equipped with a plurality of supporting rollers along central transmission shaft circumference in the annular guard plate.

The support rollers are used for supporting the edges of the sliding driving structure and the shearing structure, so that the pressure borne by the central transmission shaft is reduced, and the efficiency of the central transmission shaft for driving the shearing structure to rotate is higher.

Further, the sliding driving structure comprises a linear guide rail, a sliding mounting plate and a second driving cylinder, wherein the sliding mounting plate slides along the linear guide rail, and a shearing mechanism is fixedly mounted on the sliding mounting plate.

The sliding motion of the shearing structure is realized by the second driving cylinder and the linear guide rail, and the position of the shearing structure can be actually adjusted according to production requirements.

Further, the end part of the piston rod of the second driving cylinder is connected with the sliding mounting plate through a floating joint.

Through the arrangement, the coaxiality between the second driving cylinder and the sliding mounting plate does not need to be pursued, the coaxiality precision is low, and the thrust is not reduced.

Further, the pushing component comprises two L-shaped plates and two pushing plates, the pushing plates are fixed to one shorter side of the L-shaped plates in inclined welding mode, and a square block is sleeved on the outer edges of the two pushing plates in inclined shape.

The arrangement ensures that the pouring channel after being sheared in the pushing process can slide along the inclined plane of the pushing assembly and cannot be hung on the pushing assembly.
