Description

TECHNICAL FIELD

[0001] The utility model relates to round paper tube production technical field, and specifically relates to the mechanical arm of sucking round paper tube rotation transmission. BACKGROUND

[0002] In industrial production, the transmission of round paper tubes has always been an important link. Traditional transmission methods often rely on conveyor belts or simple pushing mechanisms. When conveying round paper tubes, conveyor belts are difficult to accurately control the position and posture of the round paper tubes, especially in scenarios where round paper tubes need to be placed at specific angles or positions into subsequent processing equipment, conveyor belts are difficult to meet high-precision requirements. Moreover, when rotation operations need to be performed on the round paper tubes during the transmission process, such as adjusting the label position or processing a specific surface, the conveyor belt cannot directly implement such functions and requires additional complex mechanical structures to assist.

[0003] Simple pushing mechanisms can only achieve linear pushing and are powerless for the grasping, rotation, and transmission of round paper tubes between different height planes. In multi-process, high-precision production processes, the limitations of this traditional pushing method become increasingly apparent.

[0004] After searching, a paper bowl machine paper tube mechanical hand transmission device with publication number CN205169809U is disclosed, which includes a rack, a turntable, and a mechanical hand provided on the rack and providing paper tubes to the turntable. The mechanical hand includes a connecting arm and a sleeve ring for supporting the paper tube. One end of the connecting arm is hinged to the rack, and the other end is fixedly connected to the sleeve ring. The sleeve ring matches the paper tube. The rack is also provided with a telescopic structure for pressing the paper tube from the sleeve ring into the turntable.

[0005] The above device controls the paper tube by clamping, but the wall thickness of the paper tube is relatively thin, and the clamping force is small, which can easily cause the paper tube to shake or even fall off during adjustment. When the clamping force is tight, the paper tube is easily deformed or even damaged, and the reliability and practicality are low. UTILITY MODEL CONTENT
