Flexible wrapping machine

Abstract

The invention discloses a flexible wrapping machine. The machine comprises a separation conveying mechanism (100), a flexible multi-specification integration mechanism (200), a manual machine fixture (300), a boxing station (600) and a box sealing station (700); a piston rod of a top molding cylinder (702) at the box sealing station (700) can realize press-fitting molding of the top front side and top folded edges of a packaging box in one-time extending; a bottom side sealing turning cylinder (728) at the box sealing station (700) can drive a bottom side sealing turning plate (729) to turn to press-fit two bottom folded edges of the packaging box synchronously; and one-time box sealing can be realized through cooperation of the top molding cylinder (702) and the bottom side sealing turning cylinder (728) at the box sealing station (700). With the machine, flexible change of multiple specifications of milk bag units and multiple specifications of packaging boxes can be realized, and one-time boxing and one-step box sealing can be realized.

Description

technical field [0001] The invention relates to the technical field of milk package packaging, in particular to a flexible wrapping machine capable of flexible conversion of milk package units of various specifications and packaging boxes of various specifications, and one-time packing and one-step sealing. Background technique [0002] The existing Kangmei wrapping machine has four stations in the packing box process: pulling the box into place, putting the milk bag into the box, sealing the bottom edge, and sealing the top. In actual use, the chain conveying capacity of the wrapping machine is worn and the positioning is not accurate. And the sealing of the box is inaccurate. If there are parallel openings not exceeding 5mm on both sides of the box, and the tongue edge of the top cover with a width of no more than 5mm is exposed, the specific manifestation is: one side of the tongue edge of the top cover is exposed (adhesive glue points on the front, rear and bottom side pa...

[0002] The existing Kangmei wrapping machine has four stations in the packing box process: pulling the box into place, putting the milk bag into the box, sealing the bottom edge, and sealing the top. In actual use, the chain conveying capacity of the wrapping machine is worn and the positioning is not accurate. And the sealing of the box is inaccurate. If there are parallel openings not exceeding 5mm on both sides of the box, and the tongue edge of the top cover with a width of no more than 5mm is exposed, the specific manifestation is: one side of the tongue edge of the top cover is exposed (adhesive glue points on the front, rear and bottom side panels) disengagement, the top tongue edge is bent and one side warps), the middle part of the top cover tongue edge is exposed (the glue point of the top tongue edge is disengaged, and the top tongue edge is bent and warped in the middle), the middle part of the top cover is warped ( The top cover of the carton is seriously warped, and the glue spots on the tongue edge of the top cover are not well bonded) and other problems

The analysis of its functional modules into the box, generally speaking, the drawing of carton boards, integration, clamping, sub-packaging, and pushing will not directly cause wrapping errors; while milk cartons are positioned in the translation of the chain, and the bottom of the carton boards is glued to the edge. Wrapping errors will be directly caused by edge pressing, edge folding and sticking of the top of the carton board, mainly reflected in: too many moving mechanisms, too complicated structure, too frequent movement; too soft material, small size of structural parts and insufficient rigidity ; The matching precision of mechanical coupling parts is too low, serious wear and other problems

In addition, indirect errors will also occur due to the carton board’s own error, packaging material hardness, weather temperature, and humidity changes. For example, the control size of the pure milk carton is often lower than the lower limit, and the front side plate is bulging after the bottom is formed; the outer side of the pure milk carton is covered with film. , the difference in tension between the two sides causes the carton to have large curvature and rebound tension; the film on the front and rear sides of the pure milk carton affects the adhesive force of the glue point; Warped
