Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of packaging machinery, in particular to a kind of bag collecting equipment of packaging bag welding nozzle machine. BACKGROUND

[0002] In food production packaging, packaging bag is widely used due to its convenient eating and carrying characteristics, especially in some tea or jelly product packaging, which has great market demand. Currently, such packaging bags are often produced by welding nozzle machine.

[0003] With the improvement of technology, the output efficiency of welding nozzle machine is getting higher and higher. It can output multiple welding completed packaging bags at a time within a period of time. If the output packaging bags are still collected and arranged by manual, it not only increases labor cost, but also limits the efficiency of automated production.

[0004] To solve the above problems, the prior art CN103879594A designs an automatic feeding device of welding nozzle machine, which discloses a device for collecting through a chute installed on the filling station. The chute on the material guiding device can be transported to the filling station by the pushing mechanism, thereby realizing the collection of packaging bags and the output of the full chute.

[0005] However, the above-mentioned scheme still has certain defects, including: 1. It does not disclose how to transport the packaging bag into the chute. Especially when welding nozzle machine is welding, the packaging bag is generally in a horizontal or suction nozzle opening upward posture. The automatic feeding device alone cannot realize the overturning and feeding of the packaging bag into the chute. 2. The distance between the filling stations is too close, which causes the bag body to interfere with each other when inputting the packaging bag into the chute of two or more filling stations at the same time. The close filling stations also make the layout of the pushing mechanism below too compact. 3. The pushing mechanism is too complex, which makes it more prone to damage and increases maintenance cost.

[0006] To solve the above problems, the present scheme designs a bag collecting equipment of packaging bag welding nozzle machine. CONTENT OF THE UTILITY MODEL

[0057] Working principle:

[0058] Pre-welding nozzle process: the bag conveying device and the nozzle conveying device of the nozzle machine convey the bag body and the suction nozzle to the bag welding platform A3 respectively, and heat seal through the welding device A2. Then the suction disc of the bag welding platform A3 sucks the packaging bag and delivers it to the direction of the variable-distance horizontal moving device 1 through reciprocating horizontal movement.

[0059] Variable-distance horizontal moving process: the variable-distance horizontal moving platform 11 connected to the end of the bag welding platform A3 sucks two packaging bags B3 through the first bag suction device 12 and the second bag suction device 14 respectively. During the reciprocating movement of the bag welding platform A3, the variable-distance cylinder drives the horizontal moving slider 13 to slide on the variable-distance horizontal moving platform 11, thereby adjusting the distance between the first bag suction device 12 and the second bag suction device 14, and finally placing the packaging bags B3 on the bag receiving platform 222 above the turnover support 22.

[0060] Turnover and bag pushing process: after the turnover support 22 receives the packaging bags B3, the turnover cylinder 23 operates to drive the turnover piece 221 to swing 90° along the rotation shaft through the linkage pull rod 231, and the suction nozzles B1 of the two packaging bags on the bag receiving platform 222 are vertically downward placed on the bag falling section 2411 of the docking conveying seat 24. Then the bag pushing cylinder 2111 operates to drive the bag pushing top rod 2112 to push the packaging bags B3, so that the suction nozzles B1 of the packaging bags enter the suction nozzle sliding groove 321 of the chute 32 along the docking section 2412.

[0061] Bag collecting and outputting process:

[0062] First step: when the chute 32 at the filling station is filled with packaging bags B3, the first chute clamping cylinder 3331-A and the second chute clamping cylinder 3331-B drive the first chute clamping plate 3332-A and the second chute clamping plate 3332-B to rise and clamp the chute 32 on the falling position groove 311 and the chute 32 on the filling station respectively.

[0063] Second step: the limiting cylinder 313 drives the two limiting fingers 314 to rotate from the vertical state to the horizontal state, and releases the chute 32 on the filling station.

[0064] Third step: the moving groove cylinder 332 operates to drive the first chute clamping plate 3332-A and the second chute clamping plate 3332-B to move outward synchronously, so that the chute 32 filled with packaging bags on the filling station is outputted outward, and the chute 32 not filled with packaging bags on the falling position groove 311 is transferred to the filling station.

[0065] Fourth step: the limiting cylinder 313 drives the limiting fingers 314 to recover from the horizontal state to the vertical state, and clamps and positions the trough 32 so that it communicates with the docking conveying seat 24, and then the new trough 32 can receive the subsequent conveying packaging bags B3.

[0066] Fifth step: the first and second groove clamping cylinders 3331-A and 3331-B drive the first and second trough clamping plates 3332-A and 3332-B to descend, and reset through the groove moving cylinder 332.

[0067] Of course, the above embodiment is only for illustrating the technical concept and characteristics of the present application, and its purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application.
