Abstract

The invention discloses a cutter drive device. The cutter drive device comprises an air cylinder (1), a cutter holder (5) and a cutter (6) installed on the cutter holder (5), wherein a gear transmission mechanism is arranged between the air cylinder (1) and the cutter holder (5), and comprises a driving rack (2), a gear (3) and a driven rack (4); the gear (3) is engaged with the driving rack (2) and the driven rack (4) separately; the driving rack (2) is coaxially connected with a telescopic rod of the air cylinder (1); and the driven rack (4) is arranged on the cutter holder (5). Through thecharacteristic that gear transmission can increase the speed, the opening and closing speed of the cutter is accelerated, the production efficiency is improved, and accordingly the influence of unstable factors of the air cylinder on the production efficiency is reduced.

Description

technical field [0001] The invention relates to a cutter driving device, which is suitable for a plastic bottle blowing machine. Background technique [0002] Existing plastic bottle blowing machines generally adopt air cylinders to directly drive the opening and closing of cutters to realize material cutting. For example, Chinese invention document CN201439207U discloses a cold cutter device, including a cutting blade, a blade pressing plate, a fixed seat, a fixing frame, a connecting plate, a cutter front plate, a cutter middle plate, a cutter rear plate and a driving mechanism, and the connecting plate is fixed. On the frame, the fixed frame is installed on the connecting plate, the fixed seat is fixed on the fixed frame, and the two cutting blades are respectively installed on the front plate of the cutter and the middle plate of the cutter through the blade pressure plate. The driving mechanism includes a cylinder, a second One rack, second rack and gear, the cylinder ...
