Material feeding mechanism of flat type bag-cover packing machine

Abstract

The invention relates to a material feeding mechanism of a flat plate type blister packaging machine. The material feeding mechanism comprises a lower clamp (50), an upper clamp (30) and a towing air cylinder (40); and also comprises a precision lead screw (100), a ball nut (20), a towing arm (60), a servo motor (70) and a synchronous belt (80); the precision lead screw (100) is fixedly arranged under the towing air cylinder (40); the ball nut (20) in contacted with the precision lead screw (100) is arranged on the precision lead screw (100); the ball nut (20) is connected with the towing arm (60); the towing arm (60) is connected with the lower clamp (50) and the upper clamp (30); and the servo motor (70) is connected with the precision lead screw (100) through the synchronous belt (80) and enables the precision lead screw (100) to rotate. The material feeding mechanism has the advantages that the structure is simple, and the digital control and adjustment can be realized.

Description

technical field [0001] The invention relates to a flat-type covering packaging machine, in particular to a material feeding mechanism of the flat-type covering packaging machine. Background technique [0002] Flat-type cover packaging machine is a kind of blister-type aluminum (PTP) / plastic (PVC), aluminum / aluminum, aluminum-plastic aluminum, Special equipment for composite sealed packaging [0003] The flat cover packaging machine is generally composed of a forming mechanism, a feeding mechanism, a heat sealing mechanism, an indentation mechanism, a forming material feeding mechanism (also called a traction mechanism), and a punching mechanism. [0004] Depend on figure 1 It can be seen that when the spline main shaft 1 rotates, it drives the traction cam 2 to rotate. When the traction cam 2 pushes the roller 3 to the high position of the cam curve, the roller 3 moves horizontally to the left while driving the roller arm 5 to push the lower link 7 to move to the left.

[0005] But this structure will be more complicated when debugging the stroke length. The adjustment method is as follows: loosen the fastening nut 6 and rotate the adjusting screw 8 to adjust the lower connecting rod 7 downward or upward, thereby changing the stroke of the traction arm 10 when it reciprocates Length: when the adjusting screw 8 is turned counterclockwise, the lower link 7 will be adjusted downward, and the stroke length will become longer; when the adjusting screw 8 is turned clockwise, the lower link 7 will be adjusted upward, and the stroke length will be shortened

Since the position of the connecting rod is adjusted in the form of a screw driven slider, the correct position can only be found by constant comparison when adjusting the forming length, and the adjustment is time-consuming
