By adopting the above technical solution, when the winding roller rotates around the bottom of the second gear, the first motor is started, and the output end of the first motor drives the second gear to rotate, thereby driving the first gear and the winding roller to rotate, completing the winding of the packaging bag.

The utility model is further configured as follows: a first placement groove is provided on the base.

The utility model is further configured as follows: a second electric push rod is fixedly mounted on a side wall in the first placement slot close to the first motor, and a cutting knife is fixedly mounted on an output end of the second electric push rod.

By adopting the above technical solution, when the winding roller that has completed winding moves to the side of the push plate, the second electric push rod is started first, and the cutting knife is driven to move by the output end of the second electric push rod, so that the cutting knife cuts off the packaging bag between the winding roller that has completed winding and the winding roller that has not started winding.

The utility model is further configured as follows: a second placement groove is provided on the base.

The utility model is further configured as follows: a second motor is fixedly mounted on a side of the support away from the first motor, an output end of the second motor passes through a side wall of the second placement groove and is fixedly connected to a screw rod, a connecting seat is threadedly mounted on the screw rod, and a pressure ring is fixedly mounted on a side of the connecting seat close to the first motor.

By adopting the above technical solution, when the packaging bag on one of the winding rollers is wound, the bottom ring is rotated to move the next winding roller to the packaging bag winding position, and then the second motor is started. The output end of the second motor drives the screw to rotate, thereby moving the connecting seat and the pressure ring. When the pressure ring moves to the bottom of the winding roller, one side of the packaging bag is pressed against the winding roller that has not started to be wound, so as to prevent the packaging bag from shifting due to instability when it is just wound.

To sum up, the utility model has the following beneficial effects: when the packaging bag on the winding roller is wound to the required thickness, the bottom ring is manually rotated to rotate the winding roller with the packaging bag wound on it to the side of the push plate, and the second motor is started. The output end of the second motor drives the lead screw to rotate, thereby moving the connecting seat and the pressure ring. When the pressure ring moves to the bottom of the winding roller to be wound, one side of the packaging bag is pressed on the winding roller, and the second electric push rod is started. The cutting knife is driven to move by the output end of the second electric push rod, so that the cutting knife cuts off the packaging bag between the winding roller that has completed winding and the winding roller that has not started winding, and then the first electric push rod is started. The output end of the first electric push rod drives the push plate to push the packaging bag on the winding roller down. The first electric push rod reduces the operation time when changing rolls, saves time and effort, and improves operating efficiency.
