Plastic uptake device

Abstract

The invention relates to the field of plastic uptake equipment, in particular to a plastic uptake device which comprises a mold assembly, a supporting assembly, a heating assembly and an adsorption assembly, wherein the mold assembly comprises a support and a lower mold base arranged on the support, the support is provided with a cavity, and the lower mold base is provided with a plastic uptake hole communicating the cavity with the space of the upper surface of the lower mold base; the supporting assembly comprises a lifting rod, the lower end of the lifting rod is fixedly connected with the bottom surface, and the upper end of the lifting rod is fixedly connected with a clamping piece; the heating assembly comprises a heating plate and an air heater, an electric heating element is arranged in the heating plate, the heating plate is connected with a rack, and the air heater is communicated with the cavity through a first air pipe; and the adsorption assembly comprises a vacuumizer, and the vacuumizer is communicated with the cavity through a second air pipe. According to the device, the two surfaces of a plastic sheet are uniformly heated, uniform extension of the plastic sheet during plastic uptake is facilitated, uneven thickness of the plastic sheet caused by excessive falling of the heated and softened plastic sheet is prevented, and the quality stability of a product is favorably improved.

Description

technical field [0001] The invention relates to the field of plastic-absorbing equipment, in particular to a plastic-absorbing device. Background technique [0002] Blister molding is a kind of plastic processing technology. The main principle is to heat and soften the flat hard plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. [0003] Blister machine is a machine that absorbs heated and plasticized thermoplastic sheets into plastic products of various shapes. The traditional plastic-absorbing process is to heat and soften the plastic sheet on one side, and then use vacuum suction to heat and soften the thermoplastic plastic sheet such as PVC and PET to form various shapes of plastic-absorbing products through the mold. Heating one side of the plastic sheet will cause the temperature of the two sides of the workpiece to be inconsisten...

AI Technical Summary

Problems solved by technology

The traditional plastic-absorbing process is to heat and soften the plastic sheet on one side, and then use vacuum suction to heat and soften the thermoplastic plastic sheet such as PVC and PET to form various shapes of plastic-absorbing products through the mold. Heating one side of the plastic sheet will cause the temperature of the two sides of the workpiece to be inconsistent. During processing, problems such as incomplete shape of the workpiece and many defects may occur. Heating the plastic sheet will make it easy to appear in the middle of the sheet. The falling phenomenon makes the thickness of the heated sheet uneven, so that the thickness difference of the product after blister molding is too large, and the quality is unstable
