Self-standing bag opening mechanism

Abstract

The invention discloses a self-standing bag opening mechanism. The device comprises a transferring mechanism, a self-standing bag is obtained by a feeding mechanism, and the self-standing bag is driven to be transferred at least at a feeding station, a bag opening station, a packing station and a discharging station sequentially. In addition, in the transferring process, the transferring mechanismalways keeps a first side face of the self-standing bag fixed, the bag opening mechanism is provided with a first pulling mechanism and an air blowing mechanism, the first pulling mechanism clamps asecond side face or pulls the second side face to the first side face after adsorption and fixing, and after the second side face is pulled by a set distance through the first pulling mechanism, the air blowing mechanism blows air with set pressure and flow speed into the self-standing bag. The transferring mechanism adopts a rotary table. The rotary table is provided with an adsorption mechanismand a clamping mechanism so that it can be ensured that the self-standing bag is firmly fixed and positioned in the process that a transferring table drives the self-standing bag to be transferred, and the self-standing bag is prevented from falling or being misplaced in the transferring process. The bag opening mechanism can efficiently, quickly and sufficiently expand the self-standing bag, andpacking operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of stand-up pouch packaging, and in particular relates to a stand-up pouch opening mechanism. Background technique [0002] Stand-up bag (Doypack) refers to a flexible packaging bag with a horizontal support structure at the bottom. It does not rely on any support and can stand on its own regardless of whether the bag is opened or not. Since the stand-up bag manufacturer and the stand-up bag packaging company are often not the same company, then In order to reduce the space occupation of stand-up bags and facilitate transportation management, stand-up pouch manufacturers often flatten and pack stand-up pouches, but stand-up pouch packaging companies need to fully open the flattened stand-up pouches when filling materials, so that they can be transported to The stand-up pouch is fully filled with materials, which requires a set of stand-up pouch packaging machine to open, fill and seal the stand-up pouch. ...

AI Technical Summary

Problems solved by technology

Although it provides a device for opening stand-up pouches, the existing problem is that there are many bag-opening actions, the process is complicated, the bag-opening efficiency is low, and it needs to be manually put into the stand-up pouch; in addition, it also has the problem of "bag After the bottom is pulled apart, the vacuum solenoid valve connected to the upper suction cup 3 and the lower suction cup 2 of the bag bottom is closed, the longitudinal cylinder 7 is reset, and the stand-up bag 12 is blown out of the bag opening machine and enters the collection box under the action of the compressed air blown out by the air blowing pipe 8 Due to the randomness of blowing force, it is extremely easy to cause the blowing position of stand-up bags to be scattered, which is not conducive to the continuous automatic production of collection and next process
