Abstract
Description
Technical Field
[0001] The utility model relates to a spider-hand conveying arm calibration tool for a cigarette-making machine, belonging to the technical field of cigarette production. Background Art
[0002] At present, in the production process of cigarettes in cigarette factories, the main cigarette making machines used are PT70, ZJ112, ZJ116, ZJ118, etc. In the above models, the transition of cigarettes from the cigarette conveying rail to the cigarette inlet drum of the assembler is completed by spider hands. Most of the existing spider hand mechanisms use 6 to 8 (selected according to the length of the cigarette) conveying arms, on which suction claws are installed. The negative pressure air is used to absorb the cigarettes, and the double-length cigarettes cut by the cutting system can be smoothly and gently conveyed to the inlet drum groove of the assembler, without the cigarettes hitting the head and the appearance is not easily damaged.
[0003] When the spider arm is conveying cigarettes, the transmission box of the mechanism and the transmission shaft of the rotating arm rotate at high speed and rub against the two skeleton oil seals. The internal heat dissipation conditions of the spider arm are poor, the lip temperature of the skeleton oil seal is high, and the oil seal fails due to aging, deformation and wear, resulting in oil leakage. The leaked oil enters the clean air channel and contaminates the cigarettes. In order to ensure product quality and normal operation of the equipment, the spider arm skeleton oil seal must be replaced regularly.
[0004] When replacing the oil seal, the height of the conveyor arm is calibrated according to the position of the fixed claw of the cigarette receiving wheel. The calibration accuracy is insufficient, which makes it easy for the spider hand to drop cigarettes. The traditional spider hand calibration method uses a flower plate calibration, which requires all the suction claws on the conveyor arm to be removed, and then the flower plate is installed to adjust the height of the conveyor arm. The adjustment is time-consuming and labor-intensive, which seriously affects the production efficiency of the equipment. Utility Model Content

Only two suction claws need to be disassembled throughout the process, which greatly saves the calibration time, improves the accuracy of the spider hand, and reduces the phenomenon of the spider hand dropping cigarettes.
[0009] Further preferably, a blind hole matching the shape of the fixed arm is provided inside the telescopic arm, one end of the fixed arm extends into the telescopic arm, and an interference fit is formed between the blind holes of the fixed arm and the telescopic arm.
