Description

Technical Field

[0001] The utility model relates to the technical field of cutting and punching waste edges, in particular to a device for cutting and punching waste edges of pulp molded three-dimensional products. Background Art

[0002] After the pulp molded three-dimensional product is cut, the waste edge of the product is separated from the product, and it needs to be taken away by people from the fixture during waste edge cleaning; because the waste edge is still a whole, it is not easy to take it off the fixture, which increases the workload and working intensity of the operator; currently, after the pulp molded three-dimensional product is cut, the product and the waste edge need to be taken away by the operator manually from the fixture. The product can be blown by air pressure, but the waste edge cannot be blown away by air pressure and needs to be taken off manually by the operator. And the waste edge is at the bottom and has a very small gap with the fixture, and the operator needs to use force to take it off, which greatly increases the working intensity and working time, thus reducing the output and efficiency of the production line. This patent punches the waste edge after cutting, and the operator can easily take away the waste edge, greatly reducing the working intensity, thereby improving the working output and efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment

[0021] A device for cutting and punching the waste edges of three-dimensional pulp molding products includes a base 1 of a circular cutting machine and a base 2 of a fixture. An installation cavity is formed inside the base 2 of the fixture. A first through hole is formed inside the base 2 of the fixture. A first air pressure pipe 3 adapted to the inner diameter of the first through hole is detachably connected inside the first through hole. The first air pressure pipe 3 is located inside the installation cavity. A connection through hole is formed at one end of the first air pressure pipe 3. A connection conduit is arranged inside the connection through hole. One end of the connection conduit away from the first air pressure pipe 3 is detachably connected to a cylinder 4. A connecting rod 5 is arranged at the end of the cylinder 4 away from the connection conduit. A punch 6 is detachably connected to the end of the connecting rod 5 away from the cylinder 4. A bracket 7 is arranged on the inner bottom wall of the installation cavity. The cylinder 4 is detachably connected to the upper end of the bracket 7. The connection conduit, the cylinder 4, and the connecting rod 5 are all located inside the installation cavity. A second through hole is formed inside the base 2 of the fixture. A second air pressure pipe 8 is arranged inside the second through hole. The size of the second air pressure pipe 8 is larger than that of the first air pressure pipe 3. A circular cutting fixture 9 is arranged on the upper surface of the base 2 of the fixture. The size of the circular cutting fixture 9 is smaller than that of the base 2 of the fixture. A product 10 is arranged at the upper end of the circular cutting fixture 9. A waste edge 11 is arranged at the lower end of the product 10. A circular cutting working chamber 12 is arranged on the upper surface of the base 1 of the circular cutting machine. A fixture moving platform 13 is arranged on the upper surface of the base 1 of the circular cutting machine. The base 2 of the fixture is installed on the upper surface of the fixture moving platform 13. An operating rod is arranged on the inner bottom wall of the circular cutting working chamber 12. A circular cutting knife 14 is installed at the lower end of the operating rod. The number of the fixture moving platform 13 and the circular cutting knife 14 is two, and they are evenly distributed inside the circular cutting working chamber 12.

[0022] In order to reduce the working intensity and working time, thereby improving the production line output and efficiency, as shown in the appendix Figures 1-3As shown in the figure, the present application adopts the following structure. Through the cooperation of the base 1 of the ring cutting machine, the base 2 of the fixture, the first air pressure pipe 3, the air cylinder 4, the connecting rod 5, the punch 6, the bracket 7, the second air pressure pipe 8, the ring cutting fixture 9, the product 10 and the waste edge 11, during the use process, the base 2 of the ring cutting fixture 9 and the fixture are made, and the first air pressure pipe 3 is additionally added to the base 2 of the ring cutting fixture 9 to drive the air cylinder 4. At the same time, the air cylinder 4 is located inside the ring cutting fixture 9. When the product 10 is cut by the ring cutting tool 14, the product 10 comes out of the ring cutting working chamber 12. The gas in the external air pump is introduced into the second air pressure pipe 8, and the second air pressure pipe 8 is activated to blow up the product 10. After the product 10 is blown up, the gas in the external air pump is introduced into the first air pressure pipe 3, and the air cylinder 4 is activated. The air cylinder 4 drives the punch 6 (or the tool) to cut off the waste edge 11. Subsequently, the air cylinder 4 returns to its original position, and the operator takes away the product 10 and the waste edge 11. A punch 6 (or a tool) can be used on the air cylinder 4, which can be applicable to products 10 of different sizes and thicknesses. When choosing the position to break through the waste edge 11 of the product 10, it should be selected below the cutting line of the product 10 and not exceed the cutting line to prevent the product 10 from not being blown away and being damaged by the punch. At the same time, the air cylinder 4, the punch 6 (or the tool), the first air pressure pipe 3, and the second air pressure pipe 8 are all detachable. If the product 10 is not produced, the accessories can be used on other ring cutting products 10 to save costs. Thus, the working intensity is reduced, the working time is reduced, and the production line output and efficiency are improved.
