Diaphragm flexible conveying belt device of bag machine

Abstract

The invention discloses a diaphragm flexible conveying belt device of a bag machine. The device comprises a machine body, an upper diaphragm conveying mechanism, an upper diaphragm winding roller, anupper diaphragm driving roller, a driving pressure roller, a first sensor and a second sensor; the upper diaphragm driving roller is used for receiving upper diaphragms leaded out from the upper diaphragm winding roller; the driving pressure roller is pivoted to the machine body, and is positioned above a pressing station; the driving pressure roller is used for receiving the upper diaphragms output from the upper diaphragm driving roller, so that the upper diaphragms between the upper diaphragm driving roller and the driving pressure roller form pasting sections; the first sensor and the second sensor are arranged on the machine body; the first sensor is used for sending first signals to the upper diaphragm driving roller when the conveying speed of the pasting sections is lower than theconveying speed; and the second sensor is used for sending the first signals to the upper diaphragm driving roller when the conveying speed of the pasting sections is higher than the conveying speed.The diaphragm flexible conveying belt device of the bag machine can adjust the conveying speed of the upper diaphragms through the first sensor and the second sensor.

Description

technical field [0001] The invention relates to a bag making machine, in particular to a diaphragm flexible belt feeding device of the bag making machine. Background technique [0002] At present, the bag making machine mainly refers to the preparation machine of the pole piece diaphragm bag. The process can be summarized as follows: the lower diaphragm is conveyed by the lower diaphragm conveying mechanism, the upper diaphragm is conveyed by the upper diaphragm conveying mechanism, and the pneumatic gripper grabs the pole piece and places it on the lower diaphragm. , the upper diaphragm covers the pole piece of the lower diaphragm, and after pressing, it is then hot-melted to form a diaphragm bag, so that the pole piece is packaged before the upper diaphragm and the lower diaphragm. [0003] However, in the existing bag-making machine for pole piece diaphragm bags, since the upper diaphragm is conveyed above the lower diaphragm, it needs to cover the lower diaphragm with a ...

Problems solved by technology

[0003] However, in the existing bag-making machine for pole piece diaphragm bags, since the upper diaphragm is conveyed above the lower diaphragm, it needs to cover the lower diaphragm with a suitable strength before entering the pressing station. , the traction speed of the upper diaphragm needs to be consistent with the conveying speed of the lower diaphragm, that is, the conveying speed should not differ too much

If the conveying speed of the upper diaphragm is too fast, the conveying speed of the lower diaphragm will not keep up, that is, the conveying volume of the upper diaphragm will be greater than that of the lower diaphragm, so the upper diaphragm will be stagnated, resulting in the tension of the upper diaphragm gradually decreasing , there will be slack, it will stick to the pole piece, and it will not be flat enough

If the conveying speed of the upper diaphragm is too slow, the conveying speed of the upper diaphragm is lower than that of the lower diaphragm, that is, the conveying volume of the upper diaphragm is smaller than that of the lower diaphragm. In this way, the tension of the upper diaphragm will gradually increase, causing the upper diaphragm to It will be tight, often not adhered to the pole piece or directly broken
