Abstract
Provided is an edge insertion device for packaging bag preparation. The edge insertion device comprises four inner supporting wheels, which are located at the same height and are arranged in two rows and two lines. A rotating shaft of each inner supporting wheel is installed along the horizontal direction. The row distance between the front and rear rows is smaller than the line distance between the left and right lines. A vertical inner supporting strip is correspondingly disposed below each inner supporting wheel. The four inner supporting strips are also configured in two rows and two lines. Flat edge insertion wheels are arranged between the front and rear inner supporting strips in each line. Rotating shafts of the edge insertion wheels are installed in the front-rear direction. According to the utility model, a film tube is spread to form a quadrangle, left and right side surfaces of the square film tube are folded inwardly along a central line by the edge insertion wheels so that the left and right side surfaces are folded into the M shape, thereby completing the edge insertion process. The edge insertion device is not in need of pumping air, and avoids deformations and wrinkles of plastic films. In addition, edge insertion and embossment can be carried out simultaneously, and the embossing process has no influence on the edge insertion process.
Description
Technical field
The utility model belongs to the technical field of packaging bag making apparatus, is specifically related to a kind of packaging bag insert edge shaped device.
Background technology
In the process of packaging bag (as plastic packaging bag), a film tube cylindraceous need be converted into the packaging bag bag of square shape through the insert edge operation, so that sack can be strutted when depositing object.In order to realize this point, the insert edge operation of traditional packaging bag manufacturing process generally is performed such: as shown in Figure 1, squeeze into air toward flat-shaped film tube 5 earlier, make film tube inner space gassy, allow film tube bulging, thus flat-shaped film tube is become round shape film tube, with an insert edge wheel or insert edge plate insert edge is carried out in the both sides of bag then, form the side of " M " type.But the deficiency of above-mentioned technology is: it is suitable that the pressure of 1, inflating is difficult to control, if it is too big to inflate pressure, and plastics coating materials easy deformation then, the plastics coating materials can shrink and produces fold after gas pressure disappears; Otherwise if it is too little to inflate pressure, then plastic foil is very opened insufficiently, not in place, and the plastic foil folding will directly cause the film wrinkle at ordinary times.If the plastic film tube surface needs embossing, then this problem is more outstanding, because the plastic foil surface irregularity of embossing, the process of inflating is leaked gas easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of packaging bag insert edge shaped device is provided, and need not inflate when it carries out insert edge.
Its purpose can realize by following scheme: this packaging bag insert edge shaped device comprises four interior support wheels, the rotating shaft installation direction of support wheel is a horizontal direction in each, four interior support wheels are positioned at the sustained height position and are arranged as two row, two row, wherein before and after two the row line-spacings less than about two row the row distances; Correspondence is provided with a vertical interior support bar below the support wheel in each, and four interior support bars also are arranged as two row, two row; Be provided with flat-shaped insert edge wheel in the middle of the two interior support bars in the front and back of each row, the rotating shaft installation direction of insert edge wheel is a fore-and-aft direction.
Be preferably, the rotating shaft installation direction of support wheel is perpendicular to the line between the support wheel central point in support wheel central point and the diagonal angle in this in each.
Be more preferably, the rotating shaft of insert edge wheel is installed on the shaft seating, also is provided with the insert edge amount governor motion that can promote the shaft seating move left and right.
Be provided with interior knurling rolls in the middle of two interior support bars about each row, the rotating shaft installation direction of interior knurling rolls is a left and right directions; From vertical position, interior knurling rolls are positioned at the below of each support wheel and are positioned at the top of insert edge wheel; The every parallel rubber roll that is equipped with in interior knurling rolls next door.
Spacing between the two interior support bars in the front and back of each row from top to bottom diminishes gradually.
The utlity model has following advantage and effect:
1, the utility model can strut the film tube becomes square, and is folded into along medium line by the left and right sides face of insert edge wheel with the quadrangular membrane tube, makes the left and right sides be converted into the M font, finishes the insert edge operation.Owing to need not to inflate, avoid the distortion of plastics coating materials, wrinkle.
But 2, the position move left and right of insert edge wheel, so insert edge amount (being that the insert edge wheel inserts the depth of bag side) can be regulated.
3, insert edge and embossing can be carried out simultaneously, and the embossing operation can not influence the insert edge operation.
