Problems solved by technology

[0004] 1. The matching gap is relatively large, resulting in low accuracy of bag unfolding, and even unstable bag unfolding
[0005] 2. Due to the relatively large gap, the shaking between the parts will cause the wear of the parts, accelerate the replacement cycle of the parts, and bring inconvenience to the use

Embodiment

[0025] Such as Figure 1-2 As shown, a bag-expanding device for a fully automatic packaging machine provided in this embodiment includes a positioning plate 15 fixed to a fixed seat 6 arranged symmetrically on one side of the positioning plate 15; an upper rotating shaft is arranged between the two fixed seats 6 9. Bearings 7 are respectively sleeved on the two fixed bases 6, and the two ends of the upper rotating shaft 9 are installed in the bearings 7; the upper rotating shaft 9 is connected through the rotation of the bearings 7, which further improves the rotation flexibility of the upper rotating shaft 9.

[0026] At least one gear 10 is sleeved on the upper rotating shaft 9. Correspondingly, the other side of the positioning plate 15 is fixed with a bag-expanding mechanism 20 compatible with the gear 10; the positioning plate 15 is also equipped with a gear transmission. Mechanism 30 and driving mechanism 40; gear transmission mechanism 30 is connected with upper rotatin...

Abstract

The invention relates to a bag unfolding device of a full-automatic packaging machine. The bag unfolding device comprises a positioning plate and fixing seats which are fixedly arranged on one side of the positioning plate and are symmetrically distributed, wherein an upper rotary shaft is arranged between the two fixing seats; at least one gear sleeves the upper rotary shaft; correspondingly, a bag unfolding mechanism adaptive to the gear is fixedly arranged on the other side of the positioning plate; the positioning plate is further provided with a gear transmission mechanism and a driving mechanism; the gear transmission mechanism is connected with the upper rotary shaft and the driving mechanism respectively; and the driving mechanism drives the gear transmission mechanism to swing so as to drive the upper rotary shaft to rotate. The bag unfolding device of the full-automatic packaging machine is simple in structure and ingenious in design; the driving mechanism, the gear transmission mechanism, the upper rotary shaft and the bag unfolding mechanism are matched with one another so that a whole bag unfolding action is finished; and the automation degree is high and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automatic packaging machine components, and in particular relates to a bag-expanding device for an automatic packaging machine. Background technique [0002] With the improvement of people's quality of life, people's demand for packaging is getting higher and higher. They hope that the packaged products will be more beautiful, more efficient, and the seal will be smoother. New requirements are also put forward for packaging machines. [0003] The bag-expanding device in the prior art is to push the pendulum block through the connecting rod, and then the pendulum block drives another pendulum block to complete the bag-expanding. The action of the two pendulum blocks is completed by sliding and fitting bearings installed in slots, but this has the following defects: [0004] 1. The matching gap is relatively large, resulting in low accuracy of bag expansion, and even instability of bag expansion. [0005]...
