Ultraviolet vacuum forming device

Abstract

The invention discloses an ultraviolet vacuum forming device. The device comprises a workbench, a storage chamber is formed in the lower part of the workbench, and a vacuum pump, a negative pressure tank, a vacuum chamber and a pipeline are arranged in the storage chamber; the vacuum pump is connected with one side of the pipeline, the negative pressure tank is connected to the pipeline, and a pressure gauge is arranged on the negative pressure tank; a vacuum valve is arranged on the pipeline, and the other end of the pipeline is connected with the vacuum chamber; the vacuum chamber is connected with a vacuum channel, the upper part of the workbench is provided with a mould, and the vacuum channel runs through the storage chamber and the workbench to be connected with the mould; air suction holes are formed in the vacuum channel, the air suction holes are formed in the bottom and corners of a mould cavity, and a shell is arranged outside the mould; an ultraviolet lamp is arranged in the shell. According to the device, a vacuum forming method is adopted to manufacture the plastic model, so that the production efficiency is high, and environmental friendliness is achieved; meanwhile,the ultraviolet lamp is used for curing and forming in a short time, time is saved, and the working efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of vacuum blister packaging, in particular to an ultraviolet vacuum blister device. Background technique [0002] The vacuum blister device is a part of the vacuum packaging machine. Its molding process is mainly to use the vacuum suction generated by the vacuum pump to absorb the heated and softened thermoplastic sheet into various shapes of vacuum covers, blister trays, blisters, etc. Shells, etc., the vacuum plastic device requires easy operation, short production time of mechanical action, and the power consumption of the machine should be saved as much as possible under the same production conditions. The existing application number CN201020508127.1, a plastic-absorbing mold with miniature vacuum eyes and a plastic-absorbing device using the mold, provides a technical solution that a mold body is provided, and several vacuum eyes are uniformly arranged on the mold body, and the aperture of the vacuum ey...

Problems solved by technology

The existing application number CN201020508127.1, a plastic-absorbing mold with miniature vacuum eyes and a plastic-absorbing device using the mold, provides a technical solution that a mold body is provided, and several vacuum eyes are uniformly arranged on the mold body, and the aperture of the vacuum eyes is small , the products produced by blistering will not produce round hole-shaped bulges, and have a good plastic-absorbing effect. The problem with the vacuum-absorbing device is that this device only considers the fit between the plastic sheet and the mold, and does not consider the shape of the plastic sheet after molding. The curing method and curing time, therefore, we need to make certain improvements to the existing vacuum blister device to solve the above problems
