DH-L300-3 high speed wet towel capping machine It is the combination of robot technology, visual recognition technology and conveyor belt tracking technology. The performance of quanchuang automatic capping machine has reached the world advanced level. At the same time, it also provides strong technical support for our high automatic wet towel production line. The labeling accuracy, pasting speed and capping accuracy of the system are in a priority position in China.

It can complete a series of actions such as automatic rubber recovery, smoke exhaust from the rubber box, automatic cover removal, labeling, gluing and cover sticking. At the same time, it can select the visual education mode when changing the cover specification. Save manpower, reduce labor cost, greatly improve production efficiency and product qualification rate, and improve the degree of automation. Components, low failure rate, simplified mechanical structure, high stiffness, stable structure and convenient maintenance.

When the plastic cover is pasted on the wet paper towel bag with the wet towel gluing machine, the error of the pasting position will cause the plastic cover to press the label on the wet paper towel bag, so that the wet paper towel can not be pulled out normally. In order to solve this problem, the function and working principle of each component of wet towel capping machine are analyzed according to the pasting process. It is found that the causes of pasting position error are mainly reflected in three links: synchronous belt conveying plastic cap; Flat belt conveying wet paper towel wrap ring joint; Parallel manipulator grasping and pasting link. There are five errors in the process of synchronous belt conveying plastic cover: the dimensional error of synchronous belt's own process connection, the installation position accuracy error of synchronous belt stop, the position error of plastic cover caused by the size of synchronous belt chute, the error of plastic cover's own material deformation, and the inertial overshoot error caused by the high-speed start and stop of synchronous belt conveying plastic cover.

Through calculation, the inertial overshoot error is the key error because of its large value in all errors. In order to eliminate the inertial overshoot error, four solutions are proposed according to Hooke's Law: changing the material of the contact surface of the plastic cover, increasing the friction coefficient of the contact surface, increasing the pressure on the upper surface of the plastic cover with the torsion spring, increasing the pressure between the plastic cover and the contact surface with the vacuum adsorption device, and increasing the thrust on the side of the plastic cover with elastic deformation.
