Description

Technical Field

[0001] The invention belongs to the technical field of cotton bale packaging, and in particular relates to an automatic bag making and cotton bale packaging production line. Background Art

[0002] At present, in the cotton processing process, the main method is to manually put the prefabricated packaging bag on the surface of the packaged cotton bale, and then sew the end surface and the barcode paper to complete the production link of cotton bale sealing. The commonly used packaging bags on the market are cotton bags and plastic bags, both of which are prefabricated bags with flat bag openings. The prefabricated bag is manually put on the bagging device, and then the bale pusher pushes the cotton bale out of the bagging device, and the prefabricated bag is completely put on the cotton bale. The cotton bale is weighed on the scale and the barcode paper is manually printed. The cotton bale is sent to a special sewing platform for manual sewing. At this time, due to manual operation, the bag openings at both ends of the prefabricated bag are prone to errors, resulting in a lower product qualification rate. In addition, the labor cost is high, the bagging time is long, and the bagging efficiency is low during the cotton bale bagging process.

The automatic bag making and cotton bag sealing production line according to claim 1, characterized in that: The end face M-shaped closing finishing mechanism includes: an M-shaped closing sliding track, an M-shaped variable model, a cotton bag pressing tentacles, a ninth servo motor, a tenth servo motor, a follow-up sliding track, an eleventh servo motor, and a twelfth servo motor; the cotton bag pressing tentacles and the follow-up sliding track are arranged on the frame, the eleventh servo motor and the twelfth servo motor drive the M-shaped closing sliding track and the M-shaped variable model to move to the cotton bag bagging position to grab the cotton bag through synchronous control, the tenth servo motor drives the M-shaped closing sliding track and the M-shaped variable model to follow the cotton bag in the front and back directions, the ninth servo motor drives the M-shaped variable model to move along the M-shaped closing sliding track, and cooperates with four cotton bag pressing tentacles to tighten toward the middle to complete the M-shaped closing, the M-shaped variable model is composed of two groups of symmetrically installed V-shaped mechanisms and four groups of acupuncture suction cups, and each group of acupuncture suction cups is arranged at both ends of the V-shaped mechanism.

10. The automatic bag making and cotton bag sealing production line according to claim 9, characterized in that: The end face clamping mechanism includes an upper clamping plate, a lower clamping plate, a clamping sliding track, and a thirteenth servo motor. The thirteenth servo motor drives the upper clamping plate and the lower clamping plate to move evenly along the clamping sliding track, so that the end face of the bagged cotton bale after M-shaped closing is clamped.
