Uniformly-mixing equipment of coating polyester film coating liquid for enhancing UV printing bonding force

Abstract

The invention discloses uniformly-mixing equipment of a coating polyester film coating liquid for enhancing UV printing bonding force. The equipment comprises a tank body, a first material inlet tube,a second material inlet tube, a fixing frame, a first motor, a material inlet hopper, a controller, a power line, supporting arms, a drive belt pulley, a belt, a driven belt pulley, a main shaft, mixing blades, a material outlet valve, a circulation purification device and a high-efficiency material discharge device. According to the equipment provided by the invention, the circulation purification device is arranged at the right end of the top of the fixing frame, after the equipment starts, hot air is generated to heat the interior of the tank body to prevent the coating liquid from being solidified, and gas released from the interior of the tank body can be extracted for high-efficiency purification, so that workers are prevented from inhaling the gas to cause uncomfortability, and theequipment has high efficiency, stability and good performance; and the high-efficiency material discharge device is arranged at the bottom of the tank body, exciting force is applied in the materialdischarge process of the tank body to assist high-efficiency material discharge, the material discharge process is uniform and stable, discharge of a residual material in the tank body is facilitated,stability of the equipment during the excitation process is not affected, the effects are good, and the costs are effectively reduced.

Description

technical field [0001] The invention relates to the related field of coating liquid processing, in particular to a coating liquid mixing device for enhancing UV printing bonding force and coating polyester film. Background technique [0002] In today's printing industry, in order to improve the adaptability of printing technology and the bonding force of vacuum aluminized layer, corona treatment is usually used to increase the surface tension of PET film. The greater the surface tension of PET film, the better the relationship between PET film and printing The stronger the bonding force of the coating, especially the PET film used in UV printing technology, because the bonding force between the UV printing coating itself and the PET film is not as good as that of the traditional coating, so the PET film used in the UV printing technology pays special attention to its Surface tension, but the surface tension of the PET film after corona treatment has problems such as timeline...

[0002] In today's printing industry, in order to improve the adaptability of printing technology and the bonding force of vacuum aluminized layer, corona treatment is usually used to increase the surface tension of PET film. The greater the surface tension of PET film, the better the relationship between PET film and printing The stronger the bonding force of the coating, especially the PET film used in UV printing technology, because the bonding force between the UV printing coating itself and the PET film is not as good as that of the traditional coating, so the PET film used in the UV printing technology pays special attention to its Surface tension, but the surface tension of the PET film after corona treatment has problems such as timeliness, especially in the environment of high temperature and high humidity, the surface tension of the PET film after corona treatment is easy to attenuate. The problem of maintaining the printing tension attenuation of PET film in a humid environment has become the focus of research in the printing industry. At present, UV ink manufacturers have changed the characteristics of UV inks to enhance the adhesion of UV inks. However, due to the complexity of the components of UV inks, resulting in The modified UV ink is very unstable, so it is difficult to improve the adhesion of the ink through UV ink modification, and the development cost and risk are relatively high. It needs to be manufactured with low risk and low cost, and can be applied to ordinary UV ink printing. Coating liquid is used to solve the problem. When the coating liquid is added and mixed, it is necessary to use a mixing device to efficiently mix its formula ingredients. However, the existing mixing device is easy to solidify in low temperature weather during the mixing process. , Odors are produced, causing physical discomfort to the staff, and the internal residue is too large during discharge, resulting in increased costs and affected subsequent processing
