Description

Technical Field

[0001] This invention relates to the field of pulp molding production technology, and in particular to an integrated punching and waste removal device for pulp molding production. Background Technology

[0002] Pulp molding is a common manufacturing process used to produce paper packaging products, tableware, toys, and more. This process typically involves punching the pulp to create various shapes. Punching generates a significant amount of waste that requires timely cleaning and disposal. Traditionally, punching and waste removal in pulp molding were performed separately, requiring additional equipment and manpower. This not only increased production costs but also impacted efficiency and environmental protection. Currently, integrated punching and waste removal systems for pulp molding are widely used in the industry. With increasing market demand for environmentally friendly and efficient production, more and more companies are adopting these systems to improve efficiency, reduce costs, and minimize waste emissions.

[0003] Currently, integrated equipment boasts continuously improving technology, high levels of automation, ease of operation, and enhanced production efficiency and stability. It can also be customized to meet the production requirements of products with different specifications and shapes. Furthermore, integrated equipment is energy-saving and environmentally friendly, effectively reducing energy consumption and waste emissions, aligning with the modern concept of sustainable development for enterprises.

[0004] In current pulp molding three-dimensional products, if the product is not placed in the correct position during punching, the punching position will be offset, resulting in product defects. At the same time, the punching cavity is very small, and waste edges are very easy to get stuck in the waste removal cavity. If this is not detected in time, it will cause product defects and machine malfunctions. Furthermore, the punched products will have burrs and incomplete punching, reducing yield and output. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated punching and waste removal device for pulp molding production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated punching and waste removal device for pulp molding production includes a platform base. A pushing mechanism is provided on one side of the top of the platform base, and a punching knife is fixedly connected to the moving end of the pushing mechanism. A jig base is fixedly connected to the outer wall of the platform base near the top of the punching knife. A waste collection box is placed at the bottom of the jig base. A punching jig is fixedly connected to the outer wall of the top of the jig base. A jig limiting block is fixedly connected to one side of the punching jig. A pulp molding product is sleeved on the top of the punching jig.

[0008] Preferably, the pushing mechanism includes a punching position, a punching cutter bracket, a punching cutter, a punching cutter moving bracket, a cylinder, and a cylinder bracket. The cylinder bracket is fixedly connected to one side of the top of the platform base, the cylinder is fixedly connected to one side of the cylinder bracket by bolts, and the punching cutter is threaded to the piston end of the cylinder.

[0009] Furthermore: the punching cutter is bolted to the top side of the punching cutter moving bracket, and the punching cutter bracket is fixedly connected to the top side of the fixture base. A movable hole is provided on the top side of the punching cutter bracket.

[0010] Based on the aforementioned scheme: the punching cutter and the movable hole form a sliding fit, the punching position is opened on the top side of the punching fixture, and the punching position is adapted to the end of the punching cutter.

[0011] A better option among the aforementioned solutions is that the front side of the fixture base is fixedly connected to a system air pressure port and a system air pressure / vacuum port, and a waste removal cavity is opened on one side of the punching fixture. The waste removal cavity has a flared shape with a small opening at the top and a large opening at the bottom.

[0012] As a further aspect of the present invention: the inner end of the system air pressure port near the punching fixture is fixedly connected to the bottom end of the air pressure pipe by a thread, and a groove is provided on the top inner wall of the waste cleaning cavity.

[0013] Meanwhile, the top of the air compressor pipe is connected to an air compressor nozzle via a thread, and the inner wall of the top of the punching fixture is provided with equally spaced vacuum suction holes.

[0014] As a preferred embodiment of the present invention: a sealing hole is provided on one side of the inner cavity of the top of the punching fixture, and the top circumference of the air compressor pipe is fixedly connected to the sealing hole through a sealing ring.

[0015] Meanwhile, the waste collection box has a fitting hole on the side directly below the waste cleaning cavity, and the inner walls of the two sides of the waste collection box near the fitting hole are respectively connected to a rotating shaft by threads.

[0016] As a preferred embodiment of the present invention: trapezoidal guide plates are rotatably connected to the outer walls of the two ends of the rotating shafts, and an adsorption patch is adhered to the top of the trapezoidal guide plate, and the trapezoidal guide plate and the fitting hole are mutually compatible.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This integrated punching and waste removal device for pulp molding production connects the system's air pressure port and air pressure / vacuum port to an air pressure / vacuum system. The system's air pressure / vacuum port is connected to the inner cavity of the punching fixture. Multiple sets of vacuum suction holes located at the top of the punching fixture adsorb and fix the pulp molding product, ensuring that the pulp molding product does not shift in position during punching. After the pulp molding product is punched, the system's solenoid valve controls the switching between air pressure and vacuum pipelines. Air pressure is used to blow up the pulp molding product, making it easy for the operator to remove it. Simultaneously, the system's air pressure port and air pressure pipe drive the air pressure nozzle to spray air, using the airflow to blow the waste edges into the waste collection box. After the punching cutter retracts to its position, the air pressure nozzle stops spraying air, and the waste edges remaining from punching flow into the waste collection box through the waste removal cavity, completing the collection of waste edges. The funnel-shaped waste removal cavity, with a small upper opening and a larger lower opening, facilitates the falling of waste edges and reduces workload.

[0019] 2. This integrated punching and waste removal device for pulp molding production, through a push mechanism including a punching position, a punching knife support, a punching knife, a punching knife moving support, a cylinder and a cylinder support, achieves accurate punching on one side of the pulp molding product, effectively ensuring the quality of punching the pulp molding product.

[0020] 3. This integrated punching and waste removal device for pulp molding production pushes the waste collection box to the bottom of the fixture base and rotates the trapezoidal guide plate, causing the trapezoidal guide plate to flip upward. At this time, the adsorption patch and the side of the fixture base near the bottom opening of the waste removal cavity are magnetically attracted and fixed to each other. The inclined surface of the trapezoidal guide plate faces the inner cavity of the waste collection box. When the waste edge falls from the waste removal cavity, it is guided by the inclined surface of the trapezoidal guide plate into the waste collection box, which prevents the waste edge from shifting and leaking out of the inner cavity of the waste collection box during the fall. When not in use, the trapezoidal guide plate is flipped so that the inclined surface of the trapezoidal guide plate fits with the inclined surface of the fitting hole, which improves practicality.

[0033] Example 1:

[0034] An integrated punching and waste removal device for pulp molding production, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a platform base 1, a pushing mechanism is provided on one side of the top of the platform base 1, and a punching knife 9 is fixedly connected to the moving end of the pushing mechanism. A jig base 3 is fixedly connected to the outer wall of the platform base 1 near the top of the punching knife 9. A waste collection box 2 is placed at the bottom of the jig base 3, and a punching jig 5 is fixedly connected to the outer wall of the top of the jig base 3.

[0035] A fixture limiting block 4 is fixedly connected to one side of the punching fixture 5, and a pulp molded product 6 is sleeved on the top of the punching fixture 5.

[0036] To facilitate punching of pulp molded product 6; such as... Figure 1 , Figure 2 and Figure 3 As shown, the pushing mechanism includes a punching position 7, a punching cutter bracket 8, a punching cutter 9, a punching cutter movement bracket 10, a cylinder 11, and a cylinder bracket 12. The cylinder bracket 12 is fixedly connected to one side of the top of the platform base 1, the cylinder 11 is fixedly connected to one side of the cylinder bracket 12 by bolts, and the punching cutter 9 is threadedly connected to the piston end of the cylinder 11.

[0037] The punching cutter 9 is bolted to the top side of the punching cutter moving bracket 10, and the punching cutter bracket 8 is fixedly connected to the top side of the fixture base 3. A movable hole is provided on the top side of the punching cutter bracket 8, and the punching cutter 9 is slidably fitted with the movable hole. The punching position 7 is provided on the top side of the punching fixture 5, and the punching position 7 is adapted to the end of the punching cutter 9.

[0038] By starting the cylinder 11, the punching knife moving bracket 10 is pushed to the left. The punching knife 9 at the top of the moving punching knife moving bracket 10 is slidably connected in the movable hole. The end of the punching knife 9 moves toward the punching position 7, accurately punching one side of the pulp molded product 6, effectively ensuring the punching quality of the pulp molded product 6.

[0039] In order to effectively fix the pulp molded product 6 and ensure the accuracy of punching the pulp molded product 6; such as Figure 4 , Figure 5 and Figure 6As shown, a system air pressure port 13 and a system air pressure / vacuum port 14 are fixedly connected to one side of the front of the fixture base 3, and a waste removal cavity 15 is opened on one side of the punching fixture 5. The waste removal cavity 15 has a flared mouth structure with a small upper opening and a large lower opening. The system air pressure port 13 is fixedly connected to the bottom end of the air pressure pipe 16 near the inner end of the punching fixture 5 by a thread. A groove is opened on the top inner wall of the waste removal cavity 15. An air pressure nozzle 18 is connected to the top end of the air pressure pipe 16 by a thread. Vacuum suction holes 17 are evenly distributed on the top inner wall of the punching fixture 5.

[0040] A sealing hole 19 is provided on one side of the inner cavity of the top of the punching fixture 5, and the top circumference of the air compressor pipe 16 is fixedly connected to the sealing hole 19 through a sealing ring.

[0041] By connecting the system air pressure port 13 and the system air pressure / vacuum port 14 to the air pressure / vacuum system, and connecting the system air pressure / vacuum port 14 to the inner cavity of the punching fixture 5, the pulp molded product 6 is adsorbed and fixed through multiple sets of vacuum suction holes 17 located at the top of the punching fixture 5, ensuring that the position of the pulp molded product 6 does not shift during punching. After the pulp molded product 6 is punched, the switching between air pressure and vacuum pipelines is controlled by the solenoid valve in the system, and the pulp molded product 6 is blown up by air pressure for easy... The operator removes the pulp molding product 6. At the same time, the air compressor nozzle 18 is driven to spray air through the system air compressor port 13 and air compressor pipe 16. The airflow blows the waste edge into the waste collection box 2. After the punching knife 9 is withdrawn to the position, the air compressor nozzle 18 stops spraying air. The waste edge remaining after punching flows into the waste collection box 2 through the waste cleaning cavity 15, completing the collection of waste edge. The funnel-shaped waste cleaning cavity 15 has a small opening at the top and a large opening at the bottom, which makes it easier for the waste edge to fall and reduces the workload.

[0042] Example 2:

[0043] An integrated punching and waste removal device for pulp molding production, such as Figure 7 As shown, in order to ensure that the waste edge does not deviate or leak out when falling from the waste cleaning cavity 15, this embodiment makes the following improvements based on embodiment 1: the waste collection box 2 is provided with a fitting hole 22 on the side directly below the waste cleaning cavity 15, and the inner walls of the two sides of the waste collection box 2 near the fitting hole 22 are respectively connected to the rotating shaft 20 by threads. The outer walls of the ends of the two rotating shafts 20 are rotatably connected to the trapezoidal guide plate 21, and the top of the trapezoidal guide plate 21 is adhered with an adsorption patch 23. The trapezoidal guide plate 21 and the fitting hole 22 are mutually compatible.

[0044] In use, push the waste collection box 2 to the bottom of the fixture base 3 and rotate the trapezoidal guide plate 21 so that the trapezoidal guide plate 21 flips upward. At this time, the adsorption patch 23 and the side of the fixture base 3 near the bottom opening of the waste cleaning cavity 15 are magnetically attracted to each other. The inclined surface of the trapezoidal guide plate 21 faces the inner cavity of the waste collection box 2. When the waste edge falls from the waste cleaning cavity 15, it is guided by the inclined surface of the trapezoidal guide plate 21 to fall into the waste collection box 2, which avoids the waste edge from shifting and leaking out of the inner cavity of the waste collection box 2 during the falling process. When not in use, the trapezoidal guide plate 21 is flipped so that the inclined surface of the trapezoidal guide plate 21 fits with the inclined surface of the fitting hole 22, which improves the practicality.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
