Automatic film tearing cutting machine for SMC (sheet molding compound)

Abstract

An automatic film tearing cutting machine for SMC (sheet molding compounds) comprises a film tearing and sheet feeding device, a cutting device and a sheet picking device. The film tearing and sheet feeding device comprises an upper film tearing rotary drum, a lower film tearing rotary drum, a main sheet feeding rotary drum and a driven sheet feeding rotary drum, the upper film tearing rotary drum and the lower film tearing rotary drum are respectively matched with an upper film and a lower film, the main sheet feeding rotary drum and the driven sheet feeding rotary drum are matched with a middle core, and the various rotary drums are driven by a servo motor via a transmission mechanism; the cutting device comprises a cutting support, a lead screw, a sliding rod and a slider are mounted in the cutting support, the lead screw is driven by a second servo motor, and a blade is connected to the lower side of the slider and is driven to rotate by a third motor; and the sheet tanking device comprises a sheet picking framework, more than two sheet picking rotary drums are mounted in the sheet picking framework, are matched with a cut core, and are mutually driven by a motor via a transmission chain, and sheet picking plates are arranged below the sheet picking rotary drums and are driven by a picking sliding mechanism to pick out a cut and molded core.

Description

technical field [0001] The invention relates to an automatic film-tearing cutting machine for SMC sheets, which belongs to the field of plastic machinery. Background technique [0002] SMC is a new type of molded composite material. With the gradual maturity of its materials and processes, its application range is becoming wider and wider, such as bumpers, fenders, masks, etc. used in automobiles, as well as construction, electronics, etc. in the industry. The SMC sheet includes an intermediate core material and a PE film covering the upper and lower layers of the intermediate core material. Before being used for production, the upper and lower PE films need to be torn off, and then the intermediate core material should be cut to make the size of the core material conform to the mold. According to the production requirements, the cut core material is put into the mold for compression molding. However, the above-mentioned steps in the prior art are all carried out manually,...

AI Technical Summary

Problems solved by technology

However, the above-mentioned steps in the prior art are all carried out manually, the production efficiency is low, the speed is slow, the labor intensity is high, and the labor cost is high. Especially, the manual operation will touch the core material, sometimes pollute the core material, and cause the product in the mold to be scrapped.
