Detailed Embodiment

[0018] In order to enable those skilled in the art to better understand the utility model, the technical solution of the utility model will be further described below in conjunction with the drawings and embodiments.

[0019] As Figures 1-3 shown, a cutting device for plastic suction products of the utility model includes a processing table 1, an L-shaped plate 11 is fixed on the upper end of the processing table 1, a cylinder 12 is installed on the upper side of the L-shaped plate 11, the output shaft of the cylinder 12 is connected with a mounting plate 13, a motor 14 is installed on the lower side of the mounting plate 13, and the output shaft of the motor 14 is connected with a cutting knife 15;

[0020] The upper surface of the processing table 1 is provided with a positioning mechanism. The positioning mechanism includes four chutes 2 machined on the upper side of the processing table 1. The four chutes 2 are distributed in a cross shape. A slider 21 is slidably assembled in the chute 2. A positioning block 22 is fixed on the upper side of the slider 21. A first cylinder body 23 is installed inside the processing table 1. A first piston rod 24 is hermetically and slidably assembled in the first cylinder body 23. The upper end of the first piston rod 24 is connected with a lifting plate 25. A hinge rod 26 is hinged on the upper side of the lifting plate 25. The upper end of the hinge rod 26 is hinged with the lower side of the slider 21. A second cylinder body 27 is installed inside the processing table 1. The second cylinder body 27 is communicated with the first cylinder body 23 through a pipeline 28. A second piston rod 29 is hermetically and slidably assembled in the second cylinder body 27. The upper end of the second piston rod 29 slidably penetrates through the processing table 1 and is connected with the mounting plate 13.

[0021] During use, the circular product is placed upside down in the middle of the processing table 1. Subsequently, the air cylinder 12 is started to drive the mounting plate 13 to move downward as a whole, that is, the cutting knife 15 moves downward. During this process, the mounting plate 13 will push the second piston rod 29 to move downward in the second cylinder body 27, and push the air inside the second cylinder body 27 into the first cylinder body 23 through the pipeline 28, so that the first piston rod 24 inside the first cylinder body 23 moves upward. The first piston rod 24 will drive the lifting plate 25 to move upward, and drive the slider 21 to slide outward in the chute 2 by using the hinge rod 26, that is, the four positioning blocks 22 move towards the side wall of the circular product until they contact the inner wall of the circular product to position the circular product. And the cutting knife 15 will also move downward to the bottom of the circular product. Finally, the motor 14 is started to drive the cutting knife 15 to move around the circumference of the circular product, and the cutting knife 15 cuts off the burrs on the side wall of the circular product;

[0022] After the burrs of the circular product are cut off, the air cylinder 12 is started to drive the cutting knife 15 to move upward, and the second piston rod 29 moves upward, sucking the air inside the first cylinder body 23 into the second cylinder body 27, and then the lifting plate 25 can be driven to move downward by the first piston rod 24, and the four sliders 21 are driven to approach each other by using the hinge rod 26, and the operator can take off the cut circular product;

[0023] The utility model can utilize the downward movement stroke of the cutting knife to automatically drive the four positioning blocks to move away from each other to position the circular product, without additional electrical components, with a reasonable structural design, and can quickly cut off the burrs of the circular product.

[0024] The output shaft of the motor 14 is connected with an electric telescopic rod 141, and the cutting knife 15 is fixed on the output shaft of the electric telescopic rod 141;

[0025] The right chute 2 is provided with a threaded through groove, in which a screw rod 3 is threadedly connected. One end of the screw rod 3 located inside the chute 2 is rotatably installed with an abutting block 31, which slides inside the right chute 2. The other end of the screw rod 3 is connected with a handle 32;

[0026] An exhaust port is opened at the bottom of the second tank body 27, and a pressure valve 33 is installed in the exhaust port.

[0027] According to the actual size of the circular product, the operator can drive the abutting block 31 to slide inside the right chute 2 by rotating the screw rod 3, so that the distance from the abutting block 31 to the center of the processing table 1 corresponds to the radius of the circular product. Therefore, when positioning the circular product, the sliding block 21 will be blocked by the abutting block 31 when sliding inside the chute 2. At this time, the positioning block 22 contacts the inner wall of the circular product to complete the positioning, and the second piston rod 29 will continue to move downward to push the air into the first tank body 23. Since the sliding block 21 is blocked by the abutting block 31, the first piston rod 24 cannot move upward. In this way, the pressure inside the second tank body 27 increases, causing the pressure valve at its bottom to open, and the excess air will be discharged from the exhaust port. Therefore, the positioning mechanism can adapt to circular products of different sizes and has higher practicability;

[0028] The electric telescopic rod 141 can drive the cutting knife 15 to move, and it can be adjusted according to the actual size of the circular product;

[0029] When the second piston rod 29 moves upward, it can pump the air inside the first tank body 23 into the second tank body 27. When the piston rod 24 inside the first tank body 23 has moved to the bottom, at this time the pressure valve 33 will also open, and the external air will be pumped into the second tank body 27 to ensure the normal operation of the device.

[0030] A plurality of convex platforms are installed on the side wall of the handle 32; by arranging a plurality of convex platforms on the outer side of the handle 32, the friction force can be increased, thus facilitating the operator to rotate the handle 32.

[0031] The above embodiments only exemplarily illustrate the principle and its effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
