A rotary bag rubbing device

Abstract

The invention discloses a rotary bag rubbing device. The rotary bag rubbing device comprises a semi-closed cylindrical shell with one end opened, and a limiting part, wherein a buffer return mechanism and a core body are sequentially arranged on the shell from the closed end to the opened end; the core body is movably installed in the shell; an adsorption mechanism is fixedly arranged at one end of the core body, and the other end of the core body is connected with the buffer return mechanism; the limiting part comprises a guide part and a spiral guide groove penetrating through the ring surface of the shell; one end of the guide part is fixedly connected with the outer ring surface of the core body, and a guide wheel matched with the guide groove is arranged at the other end of the guide part. The rotary bag rubbing device is capable of conducting rotary bag rubbing action on packing bags, and the phenomenon that normal bag opening is influenced by limitation caused by too tight bag opening bonding due to the width of the packing bags, viscidity of materials, blunt cutters and the like can be effectively avoided; in addition, resistance in the rotary bag rubbing action process is small so that the packing bags can be smoothly opened through rubbing. The overall operation is convenient, the structure is simple and the packing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a bag rubbing device, in particular to a rotary bag rubbing device. Background technique [0002] At present, the upper and lower adsorption mechanisms are generally used to open the packaging bags on the market. The specific steps are to first take out the multiple packaging bags placed in the storage bag tray one by one by the suction cup or suction nozzle on the bag taking device, and then place them in the predetermined packaging. Position, that is, by sucking the two sides of the bag, and then moving the upper suction head a short distance along the top of the product bag to open the bag mouth, but many bags are formed by shearing or extrusion, and the bag mouth is sticky. The closure is relatively tight, or due to the characteristics of the packaging bag itself and storage, extrusion, static electricity, watermarks and other reasons, the packaging bags are adsorbed and stuck together. At this time, the upper and lower lay...

Problems solved by technology

[0002] At present, the upper and lower adsorption mechanisms are generally used to open the packaging bags on the market. The specific steps are to first take out the multiple packaging bags placed in the storage bag tray one by one by the suction cup or suction nozzle on the bag taking device, and then place them in the predetermined packaging. Position, that is, by sucking the two sides of the bag, and then moving the upper suction head a short distance along the top of the product bag to open the bag mouth, but many bags are formed by shearing or extrusion, and the bag mouth is sticky. The closure is relatively tight, or due to the characteristics of the packaging bag itself and storage, extrusion, static electricity, watermarks and other reasons, the packaging bags are adsorbed and stuck together. At this time, the upper and lower layers of the packaging bag are closed too tightly to open. It is difficult to tear apart smoothly only by the suction of the upper and lower suction heads. Before opening the bag, the bag needs to be rubbed manually, and then transported to the bag opening device for processing. This method is inefficient, low in automation, high in cost, and unsatisfactory in effect.
