Description

Pneumatic visible inner weight pasting device for narrow-mouth cylinder

Technical Field

The invention belongs to the technical field of dynamic balance, and particularly relates to a pneumatic visual internal weight pasting device for a narrow-mouth cylinder.

Background

The existing weight sticking device sticks the glue-free surface of the aluminum foil and the weight sticking device together in a gluing mode, the sticking firmness degree is difficult to control, if the sticking is not firm, the device is easy to cause the situation that the aluminum foil falls off in the process of delivering the aluminum foil to the inside of the cylinder, and once the aluminum foil is stuck to the cylinder wall, the aluminum foil is difficult to remove due to the high viscosity of one side of the aluminum foil close to the cylinder wall, and other technical treatment is needed if the aluminum foil cannot be removed; if the attachment is too secure, the aluminum foil is difficult to detach from the device after the device delivers the aluminum foil to the attachment site, which may cause the attachment failure. And because the inside of the cylinder is basically in a closed state, the inside condition of the cylinder cannot be clearly observed by artificial naked eyes, natural light and external auxiliary light, and whether the aluminum foil reaches the weight pasting position can be judged only by measuring the length of the weight pasting rod which penetrates into the inside of the cylinder. Therefore, a new weight applying device is needed to reduce the failure rate of weight application and improve the accuracy and reliability of weight application.
