Description

Technical Field

[0001] The invention relates to the technical field of pulp molding production, and in particular to an integrated punching and waste cleaning device for pulp molding production. Background Art

[0002] Pulp molding production is a common manufacturing process used to produce paper packaging products, tableware, toys, etc. In this process, the pulp usually needs to be punched so that it can be made into products of various shapes. A large amount of waste is generated during the punching process, which needs to be cleaned and disposed of in a timely manner. Traditionally, the punching and waste removal work in pulp molding production is carried out separately, requiring additional equipment and manpower to clean and dispose of the waste. This not only increases production costs, but also affects production efficiency and environmental protection. At present, the integrated punching and waste removal device for pulp molding production has been widely used in the pulp molding production industry. With the increasing market demand for environmental protection and efficient production, more and more companies are beginning to adopt this device to improve production efficiency, reduce costs, and reduce waste emissions.

[0003] At present, the technical level of integrated devices is constantly improving, with high automation, easy operation, higher production efficiency and stability. Integrated devices can also be customized according to customer needs to meet the production requirements of products of different specifications and shapes. In addition, integrated devices are also energy-saving and environmentally friendly, effectively reducing energy consumption and waste emissions, and are in line with the concept of sustainable development of modern enterprises.

[0004] When punching holes in existing pulp molded three-dimensional products, if the product is not placed in place, the punching position will be offset, resulting in defective products. At the same time, the punching cavity is very small, and the waste edges are very easy to be blocked in the waste cleaning cavity. If it is not discovered in time, it will cause product defects and machine failures. In addition, the products after punching will have burrs and cannot be punched through, reducing the production yield and output. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an integrated punching and waste cleaning device for pulp molding production.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A punching and waste cleaning integrated device for pulp molding production comprises a platform base, a pushing mechanism is arranged on one side of the top of the platform base, a punching knife is fixedly connected to the movable end of the pushing mechanism, a jig base is fixedly connected to the outer wall of one side of the platform base close to 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 top outer wall of the jig base, a jig limiting block is fixedly connected to one side of the punching jig, and a pulp molding product is sleeved on the top of the punching jig.

[0008] Preferably: the pushing mechanism includes a punching position, a punching knife bracket, a punching knife, a punching knife motion bracket, a cylinder and a cylinder bracket, and the cylinder bracket is fixedly connected to the top side of the platform base, the cylinder is fixedly connected to one side of the cylinder bracket by bolts, and the punching knife is connected to the piston end of the cylinder by threads.

[0009] Furthermore: the punching knife is connected to the top side of the punching knife moving bracket by bolts, and the punching knife bracket is fixedly connected to the top side of the fixture base, and a movable hole is opened on the top side of the punching knife bracket.

[0010] On the basis of the above scheme: the punching knife forms a sliding fit with the movable hole, the punching position is opened on the top side of the punching jig, and the punching position is adapted to the end of the punching knife.

[0011] Among the aforementioned schemes, a better scheme is that the front side of the jig base is fixedly connected with a system air pressure port and a system air pressure / vacuum port, and a waste cleaning cavity is opened on one side of the punching jig, and the structure of the waste cleaning cavity is a trumpet-shaped with a small opening on the upper side and a large opening on the lower side.

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

[0013] At the same time, the top end of the air compressor pipe is connected with an air compressor nozzle through a thread, and the top inner wall of the punching fixture is provided with vacuum suction holes distributed at equal distances.

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

[0015] At the same time, a fitting hole is provided on one side of the waste collection box close to the bottom of the waste cleaning cavity, and the inner walls on both sides of the waste collection box close to the fitting hole are respectively connected with rotating shafts through threads.

[0016] As a more optimal solution of the present invention: the outer walls of the two ends of the rotating shaft are rotatably connected with a trapezoidal guide plate, and the top of the trapezoidal guide plate is adhered with an adsorption patch, and the trapezoidal guide plate and the fitting hole are adapted to each other.

[0017] The beneficial effects of the present invention are:

[0018] 1. The punching and waste cleaning integrated device for pulp molding production connects the system air pressure port and the system air pressure / vacuum port to the air pressure / vacuum system, the system air pressure / vacuum port is connected to the inner cavity of the punching jig, and the pulp molded product is adsorbed and fixed through multiple groups of vacuum suction holes located on the top of the punching jig, so that the position of the pulp molded product will not shift in the punching. After the punching of the pulp molded product is completed, the switching of the air pressure and vacuum pipelines is controlled by the solenoid valve in the system, and the pulp molded product is blown up by air pressure, which is convenient for the operator to take away the pulp molded product. At the same time, the air pressure port and the air pressure pipe drive the air pressure nozzle to spray air, and the air flow is used to blow the waste edge into the waste collection box. After the punching knife is withdrawn into place, the air pressure nozzle stops spraying air, and the waste edge remaining from the punching flows into the waste collection box through the waste cleaning cavity to complete the collection of the waste edge. The trumpet-shaped waste cleaning cavity has a small upper opening and a larger lower opening, which is more convenient for the falling of the waste edge and reduces the work intensity.

[0019] 2. This integrated punching and waste clearing device for pulp molding production, through the set pushing mechanism including a punching position, a punching knife bracket, a punching knife, a punching knife motion bracket, a cylinder and a cylinder bracket, can achieve accurate punching of one side of the pulp molded product, effectively ensuring the quality of the punching of the pulp molded product.

[0020] 3. This is an integrated punching and waste cleaning device for pulp molding production, which pushes the waste collection box to the bottom of the jig base and rotates the trapezoidal guide plate to flip the trapezoidal guide plate upward. At this time, the adsorption patch and the side of the jig base close to the bottom of the waste cleaning cavity are magnetically fixed to each other, and 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 cleaning cavity, it is guided by the inclined surface of the trapezoidal guide plate to fall into the waste collection box, thereby preventing the waste edge from deviating and leaking out of the inner cavity of the waste collection box during the falling process. When not in use, the inclined surface of the trapezoidal guide plate is fitted with the inclined surface of the fitting hole by flipping the trapezoidal guide plate, thereby improving practicality.
