technical field

The utility model relates to a knife-free punching and cutting integrated machine in the pulp molding tableware industry, which belongs to the technical field of pulp molding tableware.

Background technique

The existing production technology in the industry is to first use the edge trimmer with a knife for edge trimming, and then transfer the lock box products to the punching machine to complete the punching after the edge trimming is completed. Existing trimming mold is made up of upper formwork, knife plate; Lower formwork, cutter, cutter clamp, mold core form. The trimming operation depends on the positioning of the mold core, the hydraulic pressure lifts the lower template upwards, and the knife and the knife plate are squeezed to cut off the corners of the product. This type of trimming die generally has the problem of rapid wear of the cutter and the blade, and for the flatness of the blade and the blade, the required hydraulic pressure is generally greater than 10 tons. As a result, the service life of common knives and blades is short, and a special tool changer is required in the production process.

The punching operation needs to transfer the products that have been trimmed above to the punching machine for operation. The products are dirty during the transfer process, and there are problems in the punching operation positioning of the punching machine. The punching operation positioning of most products only depends on one side. There are cases where the punching angle deviation is large.

Further, the lower end of the upper template is provided with a receiving groove for the shape to be processed.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model uses the lower template and the upper template as concave-convex molds with a certain gap, and relies on the shearing force of the upper and lower templates to perform edge trimming. The punching is realized by the positioning device and the cross-cutting device. The cross-cutting cylinder completes the punching and reduces the number of tools. The wear and tear is completed after punching, and the two actions can be completed by one operation, which reduces labor costs and improves work efficiency. Compared with the original technology, taking 10 products (24-hour production) as an example, the production of this mold can save tool changers and punchers every day.
