Technical Field CL -. AN ? fe
The invention relates to a bag making machine, specifically relat s to an edge-folded : forming apparatus for a bottom-connected doypack making machite. ~
Background Technology o Doypack refers to a soft packaging bag with its bottom having a horizontal supporting - structure and can stand voluntarily without leaning on any support, which is a kind of relative new packaged form. The bottom and the sidewall of the bottom-connected doypack are made up of single film, and its bottom forms a horizontal supporting : structure after being spread.
The existing bottom-connected doypack making machine generally adopts double-layer coating material folded in half to manufacture a bottom-connected doypack, its edge-folded forming apparatus has effects of folding one edge of double-layer film material in half and forking inwardly, forming a bottom film with M-shaped cross section required by the doypack. For example, in Chinese invention patent application : description CN102248707A of "Self-standing device for full-automatic multifunctional multi-system integrated bag-making machine", the bottom-folded self-standing forming apparatus (i.e., edge-folded forming apparatus) includes a bottom-folded self-standing former, a bottom-folded forming fork wheel, a bottom-folded former and a fork wheel location adjusting device, regulate bottom-folded self-standing former by bottom-folded former and fork wheel location adjusting device. After adjusting the bottom-folded self-standing former and the bottom-folded forming fork wheel with the bottom-folded former and fork wheel location adjusting device, the bottom-folded self-standing former coordinating with the bottom-folded forming fork wheel completes bottom film forming required by self-standing function (cross section of bottom film is M shaped). The bottom film forming process is that the double-layer film material folded in half is 7 walking membrane along the bottom-folded self-standing former, during this process, = first the bottom-folded self-standing former separates the double-layer film material, then 2 the bottom-folded forming fork wheel folds one edge of the double-layer film material 5. and forks inwardly, forming the bottom film required by the doypack (i.e., cross section Fs of the bottom film is M shaped), and completing bottom-folded self-standing forming. :
The film material that has completed the bottom-folded self-standing forming produces a — bottom-connected doypack through sealing (horizontal sealing at a certain distance), = cutting, etc. The folded edge of the double-layer film material forms a bottom-connected on doypack bottom, and another edge of the double-layer film material forms a bag mouth. -
This bottom-folded self-standing forming apparatus can only complete bottom-folded ~ self-standing forming of film materials required by a row of bottom-connected doypacks, therefore, in a bag making machine equipped with only one self-standing forming apparatus, it can only produce a row of bottom-connected doypacks simultaneously, and production efficiency is lower.
Technical problem to be solved in the invention is to provide a kind of edge-folded forming apparatus for a bottom-connected doypack making machine. With this edge-folded forming apparatus, one bottom-connected doypack making machine can produce two rows of bottom-connected doypacks simultaneously, obviously improving the production efficiency of the bottom-connected doypack making machine. The technical scheme adopted is as follows:
An edge-folded forming apparatus for bottom-connected doypack making machine includes a frame and a former arranged in the frame, the former including an upper forming plate and a lower forming plate with a gap therebetween, characterized in that: the edge-folded forming apparatus also includes an edge-folded plate edge-folded mechanism, at least one left pinch roller and at least one right pinch roller; the edge-folded plate edge-folded mechanism includes a left edge-folded plate, a right edge-folded plate and an edge-folded plate position adjusting mechanism, the > edge-folded plate position adjusting mechanism located in the frame, the left edge-folded 5 plate and the right edge-folded plate installed on the edge-folded plate position adjusting . mechanism, the left edge-folded plate and the right edge-folded plate positioned in the -
N 5 left-edge and the right edge of the former respectively, and the left edge-folded plate and ,.. the right edge-folded plate both corresponding to the gap positions; the left pinch roller = and the right pinch roller respectively pressed with the left half part and the right half - part of the upper surface of the upper forming plate. | =
In the invention, the film material for the manufacture of the bottom-connected doypack . is the double-layer film material formed by the right and left edge of single-layer film ~ material folded inwardly. In this double-layer film material, the lower-layer film material includes the middle part of above-mentioned single-layer film material, and its width accounts for the half of that of the single-layer film material; the upper-layer film material includes a left part and a right part (formed by the left part and the right part of above-mentioned single-layer film material), the width of the left part and the right part respectively accounts for 1/4th of that of the single-layer film material (conventionally, : the width of lower-layer film material is slightly larger than that of the half of the single-layer film material, and the width of the left part and the right part of the upper-layer film material are both slightly less than 1/4th of that of the single-layer film material width, after being folded in half, there is a gap left between the left part and the right part for followed cutting). This double-layer film material has two folded edges, and after edge-folded forming, two folded edges both have bottom film with M-shaped cross section, and like this, the double-layer film material after edge-folded forming can be used for producing two rows of bottom-connected doypacks simultaneously with their bag mouths relative to each other.
In a preferred embodiment, above-mentioned former is configured by a film edge expanding portion and an edge-folded forming portion, the rear end of the film edge expanding portion integrally connected with the front end of the edge-folded forming portion; in the film edge expanding portion, the gap between the upper forming plate and the lower forming plate increases gradually from front to back, and the widths of the upper forming plate and the lower forming plate both reduce gradually from front to = back; in the edge-folded forming portion, the width of the upper forming plate is = consistent everywhere, and the width of the lower forming plate is consistent everywhere, -° ~~... .5 and the gap between the upper forming plate and the lower forming plate reduces " we gradually from front to back; the left edge-folded plate and the right edge-folded plate - are positioned at the left edge and the right edge of the edge-folded forming portion ~ respectively.
The effect of above-mentioned film edge expanding portion is to unfold two - folded edges of the double-layer film material, thereby making the double-layer film a material unfolded into the tubular film material with rectangular cross section, after . double-layer film material unfolded, the parts near to the two folded edges form into two edges of the tubular film material, and the upper-layer film material and the lower-layer film material are close to the upper surface of the upper forming plate and the lower surface of the lower forming plate respectively; in the process of the film material moving along the film edge expanding portion, the width of two edges of above-mentioned tubular film material increases gradually.
When above-mentioned tubular film material process is through the edge-folded forming portion, under the combined action of the edge-folded forming portion, the left edge-folded plate and the right edge-folded plate (the right edge of the left edge-folded plate and the left edge of the left edge-folded plate both inserted in the gap between the upper forming plate and the lower forming plate, the right edge of the left edge-folded plate right and the left edge of the right edge-folded plate respectively contacting with two edges of the tubular film material), two edges of tubular film material are folded inwardly in the middle part, making a M-shaped cross section for both edges of the tubular film material, and forming two bottom films required by the doypack (i.e., cross section of the bottom film is M shaped); with the tubular film material continuing to move along the edge-folded forming portion, under the combined action of the upper forming plate and the lower forming plate, the angles of three break angle reduces gradually in the bottom film of tubular film material with two M-shaped cross sections, reducing the gap between the upper-layer film material and lower-layer film material gradually, the tubular film ~ material by the edge-folded forming become flat and is exported from rear end of the > former finally and sent to the next procedure.
In a more preferred embodiment, the above-mentioned former is symmetrical in its left - and right edge (its symmetry plane divides the former into the left and right parts that are ~~. = in mutually mirrored relationship), the distance between right edge of the left : edge-folded plate and symmetry plane of the former reduces gradually from front to back, - and the distance between left edge of the right edge-folded plate and symmetry plane of = the former reduces gradually from front to back. Like this, with the tubular film material - moving along the edge-folded forming portion, the right edge of the left edge-folded ” plate abuts to the middle break angle position of the left edge bottom film of the tubular film material and applies a thrust to the right, making the middle break angle position of the left edge bottom film insert inward gradually, simultaneously, the left edge of the right edge-folded plate abuts to the middle break angle position of right edge bottom film of the tubular film material and applies a thrust to the left, making the middle break angle position of right edge bottom film of the tubular film material insert inward gradually, thereby making the bottom film on both edges of the tubular film material keep the
M-shaped cross section well, preventing wrinkling and distortion of the tubular film material in its flattening process.
The effect of the above-mentioned left pinch roller and right pinch roller is to press the left part and the right part of the upper film material of the tubular film material on the upper surface of the upper forming plate respectively, making whole tubular film material wrapped tightly on the outer surface of the former, and guaranteeing that the film material formed by the guiding of the former.

In the specific design, the left edge-folded rotating disk and the right edge-folded rotating disk are positioned on the left edge and right edge of front end of the edge-folded forming portion respectively, and the left edge-folded plate and the right edge-folded plate are positioned at the left edge and the right edge of middle part of the edge-folded forming portion respectively. In the process of edge-folded forming, the left edge-folded rotating disk and the right edge-folded rotating disk both have some inserts inserted in the gap between the upper forming plate and the lower forming plate. When the above-mentioned tubular film material is through the edge-folded forming portion, two edges of the tubular film material first contact with the left edge-folded rotating disk and the right edge-folded rotating disk respectively, under the combined action of the : edge-folded forming portion, the left edge-folded rotating disk and right edge-folded rotating disk, two edges of the tubular film material edge are folded inwardly in the middle part to complete preliminary edge-folded forming (i.e., forming the bottom film with M-shaped cross section at both edges of the tubular film material); Subsequently, further edge-folded forming is made by the edge-folded plate edge-folded mechanism.
Because the left edge-folded rotating disk and the right edge-folded rotating disk both can rotate under the drive of the tubular film material, there is rolling friction between the left edge-folded rotating disk and the tubular film material, between the right oo edge-folded rotating disk and the tubular film material, therefore, the rotating disk 7 edge-folded mechanism puts less resistance to the tubular film material in the moving ® process of the tubular film material. ~
