The main defects of the existing heat-shrinkable tube glue brushing system are as follows:

(1) The device for fixing the heat-shrinkable tube needs workers to fix the heat-shrinkable tube in advance before painting, then the ball screw system is opened to finish gluing, the fixing process is complex, the product types are numerous, and the corresponding fixing devices need to be diversified.

(2) because the heat-shrinkable tube has a certain length, the ball screw has a longer stroke, large inertia and large excess pressure, so that glue solution still continuously overflows when the ball screw stops in place due to the stroke, excess glue is generated in the heat-shrinkable tube fixing device, and the heat-shrinkable tube needs to be continuously cleaned in the later period.

(3) Because the size of pyrocondensation pipe, model are various, and the brush of ball front end also needs multiple, and the surplus glue on the other hand brush can solidify when out of work, when using once more, needs to change the brush.

(4) When the brush is replaced, the ball screw device needs to be disassembled and then replaced, and the replacement process is troublesome.

(5) although the system device reduces the work of manual glue brushing, the labor cost is not really solved because the heat shrinkable tube needs to be fixed manually before glue brushing, and only the labor intensity of workers is reduced.
