Sleeve labeling machine

A sleeve labeling machine includes at least a shrink film synchronous transmission device equipped with label feeding rollers and label pulling rollers, which can produce a synchronous guide and conveyance by feeding and pulling action against the shrink film on the center column;

• said label feeding rollers are set at the side of the first column of the center column, and at the top of the cutter device;
• said label pulling rollers are set at the side of the second column of the center column, and below said cutter device;
• said label feeding rollers can convey the shrink film on the center column down, and after the label pulling rollers pulling synchronously, said shrink film can be cut by the cutter device, forming a single shrink film sheet at the second column of said center column, and then said label pulling rollers synchronously continues pulling each shrink film down, so that the shrink film can accurately cover the surface of cans or bottles as a shrink packaging;
• said shrink film synchronous transmission device is provided a linkage gear module and a support frame, the linkage gear module is a left and right symmetrical structure, which from top to bottom is provided with two symmetrical first rotating arms, two symmetrical second rotating arms, two symmetrical third rotating arms, two symmetrical fourth rotating arms, two symmetrical first gears, two symmetrical second gears, two symmetrical third gears, two symmetrical fourth gears and two symmetrical fifth gears;
• said two first gears are connected to each other and are fixed on said support frame, one of the first gear is connected to the power equipment, so that the two first gears can be rotated in the opposite direction;
• the first gear is set on the top end of the first rotating arm, the second gear is set between the first rotating arm and the second rotating arm, the third gear is set between the second rotating arm and the third rotating arm, the fourth gear is set between the third rotating arm and the fourth rotating arm, and the fifth gear is set on the lower end of the first rotating arm;
• the third gear is connected to the label feeding rollers to simultaneous rotation, and the fifth gear is connected to the label pulling rollers to simultaneous rotation.
