To further elaborate on the scheme, the frame is a square frame with an open upper end, and the four edges of the open end of the frame are respectively provided with a plurality of the trimming devices, and the push-pull device is composed of a horizontally driven pneumatic part and a fixed seat. The fixed seat is fixed on the edge of the opening end of the frame, and the movable end of the pneumatic part is connected with the pneumatic shear. Under the action of the push-pull device, the pneumatic shears can move closer to the center of the support plate and move away from the reciprocating operation.

To further elaborate the solution, the positioning device includes a limiting column and a limiting cylinder, a plurality of the limiting columns are fixed on the support plate, and a plurality of the limiting cylinders are distributed at intervals on the edge of the support plate.

To further elaborate the solution, the frame is also provided with a collection tank, the collection tank is located below the support plate, and a waste window is formed on the side wall of the frame, and the collection tank is inclined to the waste window.

Further elaborating the solution, it also includes a position sensor, and the trimming device and the lifting device are both provided with a position sensor.

The beneficial effect of the utility model is that multiple pneumatic scissors on the frame can quickly cut out the sprue, instead of manually cutting the sprue, avoiding the situation of poor product quality caused by manually cutting the sprue, reducing the labor intensity of employees, The automatic production process technology is realized, the production cost is reduced, and the production efficiency is improved.

detailed description

A specific embodiment of the present utility model is introduced below in conjunction with accompanying drawing 1 to accompanying drawing 2.

As shown in Figures 1 to 2, the automatic shear gate device for the plastic outer cylinder of the washing machine includes a frame 1, a support plate 2, a lifting device 3, a positioning device and a trimming device; the support plate 2 is arranged in the center of the frame 1; The lifting device 3 is arranged below the support plate 2, and the positioning device is fixed on the support plate 2; the pruning device includes a pneumatic shear 4 and a push-pull device 5 connected to the pneumatic shear 4, and a driving cylinder is arranged above the pneumatic shear 4, and the push-pull device 5 is fixed on the frame 1. The lifting device 3 is composed of a lifting cylinder and a guide rod. The lifting cylinder is vertically installed on the lower part of the frame 1. The upper end of the guide rod and the movable end of the lifting cylinder are fixed on the lower surface of the support plate 2. The role of the support plate 2 in the lifting device 3 The bottom can move up and down relative to the frame 1 in a reciprocating cycle.

The frame 1 is a square frame with an upper end opening, and the four edges of the opening end of the frame 1 are respectively provided with a plurality of trimming devices. The push-pull device 5 is composed of a horizontally driven pneumatic part and a fixed seat. Fixed on the edge of the open end of the frame 1, the movable end of the pneumatic part is connected with the pneumatic shear 4. The four pneumatic shears 4 can move closer to the center of the support plate 2 and move away from the reciprocating operation under the action of the respective push-pull devices 5 .
