Automatic glue attaching volume control device and method

Abstract

The invention belongs to the technical field of the chemical fiber spinning industry. An automatic glue attaching volume control device is arranged in a glue dipping assembly of cord fabric. The gluedipping assembly comprises a glue dipping tank, a glue dipping roller arranged in the glue dipping tank and a vacuum suction unit for sucking surplus glue dipping liquid on the cord fabric obtained after glue dipping. The automatic glue attaching volume control device comprises a metering unit and a controller, wherein the metering unit is used for metering the usage amount of glue dipping liquidin the glue dipping tank within the unit time, the controller is used for controlling the intensity of negative-pressure suction of the glue-dipped cord fabric through the vacuum suction unit according to metering data fed back through the metering unit. The invention further discloses an automatic glue attaching volume control method. The structure design is reasonable, through metering of the usage amount of the glue dipping liquid, the actually-measured glue attaching volume is obtained, and through comparison with the theoretical design value of the glue attaching volume, automatic controlis achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber spinning industry, and in particular relates to an automatic control device and method for the amount of glue attached. Background technique [0002] The amount of glue attached to the cord in the dipping process is mostly controlled manually, and the adjustment method is mostly adjusted based on experience, and after adjustment, the amount of glue attached cannot be monitored during the production process, which can easily lead to changes in the amount of glue attached to the cord Large, resulting in product quality can not be guaranteed. [0003] After the existing cord is dipped in glue, the excess glue on the cord surface can be removed and controlled by two parts: the extrusion roller and the vacuum suction, and the adjustment of the negative pressure adsorption force of the vacuum glue determines the final adhesive amount of the cord. However, the adjustment of the negative pressure ...

[0003] After the existing cord is dipped in glue, the excess glue on the cord surface can be removed and controlled by two parts: the extrusion roller and the vacuum suction, and the adjustment of the negative pressure adsorption force of the vacuum glue determines the final adhesive amount of the cord. However, the adjustment of the negative pressure adsorption force of vacuum glue mostly depends on the production experience of the workers, in view of the change of the liquid level in the dipping tank during the production process, the change of the operating conditions between shifts, and the different types of cords, etc. Both may cause the amount of glue attached to the cord to fail to meet the standard, and effective monitoring and adjustment cannot be carried out. There are great technical problems, and the technology in this area is still blank in the industry, and the optimization and improvement of the dipping process cannot be realized.
