Edge Trimming Equipment and Edge Trimming Method for Pulp Molded Products

Abstract

The invention discloses a pulp molding product trimming device and a trimming method. The pulp molding product trimming device comprises a device frame, a product clamping device, sliding rails, a trimming tool bit device and an elastic ejecting pressing element, wherein the product clamping device is arranged on the device frame and capable of clamping the pulp molding product and moving the pulpmolding product to rotate around a rotating axis parallel to the lengthwise direction of the pulp molding product; the sliding rails are arranged on the device frame and perpendicular to the extension of the lengthwise direction of the pulp molding product; the trimming tool bit device is slidably connected to the sliding rails and used for perpendicularly cutting the edges of the pulp molding product on the longitudinal direction; one end of the elastic ejecting pressing element is fixedly connected to the device frame, and the other end of the elastic ejecting pressing element is connectedwith the trimming tool bit device; and under an elastic pressing force from the elastic ejecting pressing element, the trimming tool bit device can fit to the outline of the pulp molding product to cut the edges of the pulp molding product. According to the pulp molding product trimming device and the trimming method, no overlap on the pulp molding product after trimming is achieved, and burrs atthe incision are reduced.

Description

technical field [0001] The invention relates to the technical field of edge trimming of pulp molded products, in particular to an edge trimming device and a method for pulp molded products. Background technique [0002] As an environmentally friendly product, pulp molded products have been developed in China for many years. The molding methods have changed from dry pressing to wet pressing to high-quality products. The technology is constantly improving, and the demoulding slope is getting smaller and smaller. The surface of the formed products is smooth and beautiful. ; After the pulp molded product is formed, it is necessary to cut off the excess parts such as burrs and edge materials at the edge of the product, and the production of the product is completed after trimming. Existing trimming technologies for pulp molded products include plane beer trimming, rotary trimming and laser trimming. [0003] Plane beer cutting is to use a knife die to press the punching machine ...

Problems solved by technology

[0005] Laser edge trimming uses a laser generator to convert electrical energy into light, and concentrates light in the target resection area to form a high-temperature fusing material to form an incision, accompanied by dark brown burnt marks, which are more obvious for light-colored paper and plastic products; at the same time The efficiency of laser trimming is low, it is not suitable for trimming large quantities of paper and plastic products, and there are difficulties in positioning, resulting in uneven trimming
