[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figures 1 to 6The utility model provides a technical solution: a device for integrated punching and waste removal of pulp molded three-dimensional products, including a platform base 1, a cylinder bracket 2, a punching knife motion bracket 3 and a fixture base 4 are installed above the platform base 1, a punching cylinder 5 is installed between the cylinder bracket 2 and the punching knife motion bracket 3, the punching knife motion bracket 3 includes a linear guide rail and a movable bracket below, the piston rod of the punching cylinder 5 is connected to the movable bracket, and the punching cylinder 5 pushes the bracket to reciprocate on the linear guide rail when working, a vacuum cavity 401 is opened above the fixture base 4, and a blanking slot 402 is opened on the side of the vacuum cavity 401 close to the punching knife motion bracket 3, a punching fixture 6 is installed above the fixture base 4, and the punching fixture 6 A vacuum generating chamber 601 and a waste cleaning cavity 602 with openings facing downward are provided inside the punching tool 401, a vacuum suction hole 603 is provided above the vacuum generating chamber 601, a punching hole 604 is provided on the side of the waste cleaning cavity 602 close to the punching knife moving bracket 3, the length and width of the vacuum generating chamber 601 are the same as the length and width of the vacuum cavity groove 401 and are aligned up and down, the length and width of the waste cleaning cavity 602 are the same as the length and width of the blanking slot hole 402 and are aligned up and down, the punching jig 6 and the jig base 4 are assembled together to form two independent cavities, one is a closed vacuum suction chamber, and the other is a waste cleaning cavity with an opening at the bottom, and the side of the jig base 4 is provided with an air pipe joint 7 connected to the vacuum cavity groove 401 and an end connected to the top of the waste cleaning cavity 602 The jet pipe 8 of the part, a punching knife bracket 9 is installed on the upper side of the fixture base 4 close to the cylinder bracket 2, a punching knife 10 passing through the punching knife bracket 9 is installed on the upper side of the punching knife moving bracket 3, and a paper plastic product 11 is sleeved on the upper side of the punching fixture 6. A hole that matches the clearance of the punching knife 10 is opened on the upper side of the punching knife bracket 9. The height of the hole is the same as the height of the paper punching hole 604. The length and width of the paper punching hole 604 are slightly larger than the vertical section size of the punching knife 10. The punching knife 10 can be inserted into the paper punching hole 604, and at the same time, a hole with the same length and width as the vertical section length and width of the punching knife 10 is punched out for the paper plastic product 11. The air pipe joint 7 connects the system vacuum and the system air pressure. When the vacuum is connected, the vacuum suction hole 603 generates a downward suction force to push the paper plastic product 11 is sucked downward so that the paper-plastic product 11 is tightly covered on the top of the punching jig 6. When the air pressure is connected, the vacuum suction hole 603 generates an upward blowing force to blow the paper-plastic product 11 upward so that the paper-plastic product 11 automatically moves upward and separates from the punching jig 6. The jet tube 8 is connected to the system air pressure. The top of the jet tube 8 is higher than the paper punching hole 604. When the top of the jet tube 8 sprays air, a top-down airflow is formed in the waste cleaning cavity 602. The airflow can blow down the waste edge sent into the jet tube 8 by the punching knife 10. A waste collection box 12 is arranged under the jig base 4. The waste collection box 12 is an independent individual. When inserted under the jig base 4, it can receive the waste edge falling down from the blanking slot 402. When pulled out, the waste edge can be taken out from the bottom of the jig base 4.

[0026] During use, the air pipe joint 7 is connected to the system air pressure and the system vacuum through the air pipe at the same time, but the two do not work at the same time. The jet pipe 8 is only connected to the system air pressure. The worker first puts the paper plastic product 11 on the punching jig 6, and then the system vacuum extracts the gas in the vacuum generating chamber 601 through the air pipe joint 7 to form a negative pressure inside. At this time, the vacuum generating chamber 601 sucks air from the top of the punching jig 6 through the vacuum suction hole 603. Since the punching jig 6 is sleeved with a relatively compact paper plastic product 11 on the top, a negative pressure also appears between the paper plastic product 11 and the top surface of the punching jig 6. At this time, the paper plastic product 11 will move downward under the action of the external atmospheric pressure, so that the paper plastic product 11 is automatically buckled down into the punching jig 6 so that the paper plastic product 11 is automatically installed in place, thereby avoiding the problem of inconsistent punching height caused by the inadequate installation of the paper plastic product 11. When the paper plastic product 11 is installed in place, the punching cylinder 5 works to push the punching knife 10 to penetrate the paper plastic product 11 and insert it into the waste cleaning cavity 602 from the paper punching hole 604. At this time, the punching knife 10 also sends the waste edges cut from the paper plastic product 11 to the waste cleaning cavity 602. The system air pressure further connects the compressed gas to the jet pipe 8. The compressed air ejected from the top of the jet pipe 8 forms a top-down airflow in the waste cleaning cavity 602. The airflow can discharge the waste edges downward in time and drop them into the waste collection box 12 for collection. After that, the waste collection box 12 can be pulled out regularly to clean the waste edges. When the paper plastic product 11 is punched, the punching cylinder 5 drives the punching knife 10 to reset. The system air pressure further injects compressed air into the vacuum generating cavity 601 through the air pipe joint 7 to increase the air pressure in the vacuum generating cavity 601. At this time, the vacuum suction hole 603 generates an upward blowing force to blow the paper plastic product 11 upward so that the paper plastic product 11 automatically moves upward and separates from the punching jig 6 to improve production efficiency.

[0027] In summary, the device for integrated punching and waste cleaning of pulp molded three-dimensional products assembles the jig base 4 and the punching jig 6 to form a sealed cavity, the bottom of the cavity is connected to the system vacuum, and a through hole for air suction is opened on the top. When the product is sleeved on the punching jig 6, the system vacuum only needs to extract the air in the cavity to form a negative pressure, which can suck the product downward so that the product is automatically placed in place, thereby achieving the effect of highly uniform punching. At the same time, the cavity can also be connected to the system air pressure, and the system air pressure is injected with compressed air to form high pressure, which can blow the product upward so that the product automatically detaches from the top, thereby achieving the effect of convenient product removal and improving production efficiency. The jet pipe 8 is connected to the system air pressure, and the system air pressure provides compressed air sprayed out from the top of the jet pipe 8, so that a top-down airflow is formed in the waste cleaning cavity 602, and the airflow can discharge the waste edge in time, thereby avoiding the waste edge from being blocked in the waste cleaning cavity 602 and impacting the tool, thereby avoiding tool damage, thereby avoiding the situation of unqualified punching due to tool damage, thereby improving the production yield.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
