Paper box enclosure frame forming device and frame enclosure method

Abstract

The invention relates to a paper box enclosure frame forming device and a frame enclosure method. The enclosure frame forming device comprises a conveying belt assembly and a frame enclosure assembly;the conveying belt assembly is used for receiving and conveying foxing strips to a designated position and comprises two conveying belts, a driving roller and a driven roller, the two conveying beltsare symmetrically connected to the left ends and the right ends of the driving roller and the driven roller in a sleeving mode at intervals, and when the driving roller rotates, the two conveying belts are driven to rotate synchronously; the interval width between the two conveying belts is larger than the length of short edge blocks in the foxing strips and smaller than the sum of the length oflong edge blocks in the foxing strips and the length of the short edge blocks in the foxing strips; the conveying belts convey the foxing strips to the position below a mold at the designated position; and the lower long edges of the foxing strips are located under the mold, the junctions of the lower long edges of the foxing strips and the short edges of the foxing strips are arranged on the edges of the conveying belts, and the enclosure frame forming device pushes the foxing strips to turn over upwards through an enclosure frame assembly and tightly presses all the edges of the foxing strips on the mold for enclosure frame forming. The paper box enclosure frame forming device is stable in conveying, high in enclosure frame forming speed and high in flexibility.

Description

technical field [0001] The invention relates to the field of carton production, in particular to a carton enclosing frame forming device and a frame enclosing method. Background technique [0002] At present, on most domestic cigarette case production lines, before the frame-enclosing operation, the conveying device of the surrounding strip is reciprocating, that is, after the conveying device transports the surrounding strip to the designated position, it needs to be reset before the next surrounding strip can be transported. This reciprocating conveying mode causes the conveying device to have an empty return stroke after the conveying is completed, so the conveying time is wasted and the efficiency of cigarette case production is reduced. [0003] In addition, the current enclosing methods of the enclosing frame forming device are similar, and they use a fixed structure to perform enclosing with a fixed carton size, which has a narrow application range and low flexibility...

Problems solved by technology

This reciprocating conveying method makes the conveying device have an empty return stroke after conveying, so the conveying time is wasted and the efficiency of cigarette case production is reduced.

[0003] In addition, the current enclosing methods of enclosing frame forming devices are similar, and they use a fixed structure to perform enclosing of a fixed carton size, which has a narrow scope of application and low flexibility.
