By combining the specific implementation methods, the working steps of the packaging bag processing equipment are as follows:

the raw materials can be selected from a single-layer bag body, a double-layer bag body or a single-layer or double-layer plastic film, and the double-layer bag body is selected for process examples.

When the double-layer sleeved raw material bag only needs to be shaped, the shaping method can be completed through the following steps:

preparing S20 raw material: the raw material bags sleeved in a double layer are selected to be flatly stacked together, and the raw material bag openings are placed in the material adjusting space 123 by aligning the first material state adjusting device 13 to wait for operation.

S21 opening the bag opening: picking up two side edges of the bag opening through a first material state adjusting device 13, respectively grabbing each layer of bag opening edge of the bag opening of the double-layer sleeved raw material bag by the first material state adjusting device 13, and then displacing the first material state adjusting device 13 to open the bag opening.

S22 pressing the plate into a bag: the second material state adjusting device 14 enters the interior of the material through the opening of the bag in the opening state, and the adjusting workpiece 141 extends into the opening of the raw material bag.

S24 two-stage bagging: the side supporting workpiece 143 is driven by the adjusting and shifting mechanism 142 to extend into the bag opening, the material outer bag is adsorbed by the material state adjusting device I13 at the moment, the bag opening is in an open state, the inner film is adsorbed by the side supporting workpiece 143 and is in a tightening state, the relative position of the material outer bag and the bag opening of the inner film is adjusted through the extending action of the side supporting workpiece 143 to the bag opening, the distance between the bag opening of the inner film and the bag opening of the outer bag is adjusted, the extending amount of the bag opening of the inner film extending out of the bag opening of the outer bag is adjustable, and preparation is made for next setting work.

S26 outside sizing: the shaping device 12 presses the material on the adjusting workpiece 141 for shaping, the shaping device 12 may be a heat sealing device, such as a heat sealing knife, an ultrasonic point ironing machine, or a gluing and sewing machine, and is exemplified by a heat sealing knife, and during heat sealing, the shaping device 12 performs synchronous heat pressing action towards the bag mouth direction on both sides of the bag mouth of the raw material bag; the adjusting workpiece 141 is inserted into the mouth of the raw material bag and then should be located at the center of the heat sealing area when the raw material bag is subjected to pressure heat sealing, the adjusting workpiece 141 has two working and setting modes, one mode is that the adjusting workpiece 141 is a pressed piece which is arranged in a flush manner with the center of the heat sealing area, the adjusting workpiece 141 is directly inserted into the mouth of the bag to be matched with the shaping device 12 for carrying out bag mouth shaping work, the other mode is that the starting position of the adjusting workpiece 141 cannot be arranged in a flush manner with the center of the heat sealing area due to limited station space, after the adjusting workpiece 141 is inserted into the mouth of the bag, the adjusting workpiece 141 needs to be inserted into the mouth of the bag and before the shaping device 12 carries out bag mouth shaping work or moves synchronously with the shaping device 12, so that the adjusting workpiece 141 can be subjected to pressure matching shaping at the center of the heat sealing area, otherwise, the other side is easy to have poor shaping effect.

S26 reset send: and the second material state adjusting device 14 resets, and the material bag is conveyed to enter the next station through the material conveying assembly 3.

In step S24, the side-supporting workpiece 143 of the second material state adjusting device 14 performs negative pressure adsorption on the inner bag, and cooperates with the first material state adjusting device 13 under the driving of the adjusting and shifting mechanism 142 to complete the relative position adjustment of the bag opening edge between the material bag bodies, the side-supporting workpiece 143 adsorbs the inner raw material bag, at this time, the outer raw material bag is positioned by the first material state adjusting device 13, that is, the inner and outer raw material bags are respectively grabbed by the two devices, and then the two shaped devices perform relative displacement, in this case, the negative pressure mechanism 143 moves, the first material state adjusting device 13 does not move, and a relative displacement is generated between the two bags to adjust the distance between the two bag bodies, wherein the adjusted extending amount or extending amount of the bag opening edge can be specifically determined according to the actual working condition requirements.

The method also comprises the following steps of S24-1 spreading the wale between the steps of S24 and S26: the side supporting workpiece 143 is driven by the supporting driving mechanism 144 to perform telescopic action along the plane of the adjusting workpiece 141, so as to support the bag body to be flat, the side supporting workpiece 143 is driven by the supporting driving mechanism 144 to perform transverse supporting action on two sides of the adjusting workpiece 141, so that the bag body sleeved together in a stack manner can be supported to be flat, the influence of wrinkles caused by the material state adjusting device 13 when grabbing materials on the setting can be solved, the vacuum adsorption is firstly performed, then the negative pressure mechanism 143 moves to position the inner bag and the outer bag, then the side supporting is performed, the phenomenon that the inner bag near the bag opening caused by the movement of the negative pressure mechanism 143 after the side supporting and the vacuum adsorption is accumulated near the bag opening to form inner bag wrinkles in the area of the bag opening is avoided, and the accumulated wrinkles are not positioned at the bag opening but placed at the bag body below the bag opening through the action of internal feeding after the adsorption, so as to help the bag opening to be flat, also help the wrapping bag interior membrane bag to have more allowances when filling, reduce the damaged condition of interior membrane bag, if the fold is in sack department in addition, setting device 12 can be used in the inner bag part of fold during the design, can influence the design effect, can not set even, causes the defective percentage to rise, and adopts and carries out vacuum adsorption earlier then negative pressure mechanism removes the location sack, then carries out the side branch and can effectively avoid appearing the fold phenomenon that setting device 12 acts on the part and reduce the defective percentage.

Accordingly, by installing the first side-supporting workpiece 145 on the adjusting workpiece 141, the step S23 can be omitted, that is, the first side-supporting workpiece 145 replaces the first side-supporting workpiece 143 and the opening driving mechanism 144, in the step S22, the first side-supporting workpiece 145 enters the inner bag while the adjusting workpiece 141 extends into the space between the inner bags of the opened double-layered bag, and because the first side-supporting workpiece 145 has a convex arc elastic workpiece, the first side-supporting workpiece 145 tightens the inner bag while the adjusting workpiece 141 enters the inner bag, so as to achieve the effect achieved by the unfolding of the cross brace in the step S23.

When the workpiece 141 is adjusted not to be flush with the center of the heat-sealed area, a step S25 of lowering and setting is further included between steps S24-1 and S26: the adjusting workpiece 141 is driven by the adjusting and shifting mechanism 142 to move along with the shaping device 12 arranged on one side to the shaping device 12 arranged on the other side, and the shaping devices 12 arranged on two sides of the material state adjusting device II 14 press the materials on the adjusting workpiece 141 at the same time.

When the double-layer bagging needs to be subjected to bag opening edge folding after the shaping is finished at the processing assembly 1, the method can be finished through the following steps:

s3 folding: the raw material bag is folded inwards or outwards through the folding assembly 2.

S31 opening the bag opening for one section: the material positioning mechanisms 222 clamp the material or start negative pressure suction, the material positioning mechanisms 222 move away from each other to open the bag mouth, and the opening range is smaller than the maximum opening amount of the bag mouth.

S32 folding the opening of the bag: after the material positioning mechanism 222 performs the first opening action, the folding mechanism 221 folds the edge of the bag opening into or out of the bag body; the folding mode here depends on the needs of the working conditions at the time, and here, the folding into the bag body is exemplified.

S34 binding protrusion: after the folding mechanism 221 performs the folding operation into the bag body, the bag mouth edge of the raw material bag is folded inwards to form an unshaped folding structure, and at this time, the connector 26 is driven by the radial displacement mechanism 24 to perform the extending operation relative to the working space 223.

S35 close binding: when the connector 26 extends into the working space 223 in the pocket, the axial flanging mechanism 22 performs a closing action by aligning with the pocket flanging structure, and at this time, the axial flanging mechanism 22 presses the unshaped pocket flanging structure on the connector 26 to combine and fix the materials; the advantage of doing so is that the mode can improve yield and the pleasing to the eye, firm degree after the design to the design mode of other directions.

S36 reset: the devices are reset and the material positioning mechanism 222 stops positioning.

Step S33 may be added between steps S32 and S34, and step S33 is that the material positioning mechanism 222 stretches the bag opening two-stage: the material positioning mechanism 222 opens the bag mouth for the second time, the opening range is larger than the step S31 or the bag mouth is opened to the maximum, so that two sides of the raw material bag mouth, which are not folded or are not folded completely, are tensioned and straightened, the bag mouth sides can be turned over along with the bag mouth folding structure, and besides the effect of folding the sides, the bag mouth edges, especially the edges of the double-layer bag mouth overlapping sleeve can be combined in a smooth state after being tensioned and straightened, so that the combination effect can be ensured, and the requirement of the finished product rate can be met.

Wherein, in step S35, the axial hemming mechanism 22 performs a synchronous closing action with respect to the connector 26, the synchronous closing action is performed simultaneously with the closing action of the axial hemming mechanism 22, the radial hemming mechanism 25 performs an opening action along the axial direction of the rotating shaft 22131, the timing of the radial hemming mechanism 25 to the transverse bracing action of the bag opening of the raw material bag is important here, if the transverse bracing is late, the radial mechanism 25 collides with the axial hemming mechanism 22, or the bag opening cannot be combined in a flat state, if the transverse bracing is performed before the axial hemming mechanism 22, the bag opening is easy to be flattened, so that the bag opening hemming structure is easy to be partially or wholly attached to the connector 26 in advance, which may cause the product to be defective due to too long combining time, and if the bag opening passes through the two-stage opening action during the transverse bracing action of the radial hemming mechanism 25, the side edge is not completely folded, the radial flanging mechanism 25 can realize complete flanging of the side edge of the bag opening through cross bracing action, and the radial flanging mechanism 25 and the connector 26 synchronously extend in and out to achieve the aim of synchronous working more easily.

In step S36, after the devices are reset, the material positioning mechanism 222 is closed, the material positioning mechanism 222 stops positioning after being closed, and the material positioning mechanism 222 is reset and opened after stopping positioning. Because when the jointer 26 combines the raw material bag or material positioning mechanism 222 is grabbing the material and carrying out location work, the material can produce physical deformation or thermal deformation, especially under some circumstances, if the operational environment influences, there are phenomena such as adhesion between material and the jointer 26, cause the defective percentage to rise easily at this moment, and material positioning mechanism 222 carries out a pressfitting with the raw materials sack just can solve this moment, and the material can keep the leveling state after being processed.

In order to save the labor consumption of raw material feeding, straightening and the like, a step S1 of straightening and feeding can be added before the step S2: the raw material bags to be folded are placed on the feeding workbench 41, the raw material bags are conveyed to enter the next station through the feeding conveying mechanism 43 and/or the material conveying assembly 3, the adjustment between the processes can be flexibly carried out according to the working space and the processing requirements, and the S1 alignment feeding process is arranged before the S2 process for example.

Before the material bag is conveyed to the next station by the feeding conveying mechanism 43 in the step S1, the angle at which the material bag enters the mechanism of the feeding assembly 4 is adjusted by the feeding adjusting and positioning mechanism 42, the operator places the material bag at the initial position of the feeding conveying mechanism 43, and then the feeding conveying mechanism 43 conveys the material bag to the feeding adjusting and positioning mechanism 42, at this time, the feeding adjusting and positioning mechanism 42 can generate a shift effect on the material bag, the feeding conveying mechanism 43 continuously conveys the material bag until the side of the material bag is adjusted to be perpendicular to the feeding direction, and the feeding conveying mechanism 43 and/or the material conveying assembly 3 conveys the material bag to the next station.

Step S4 is also included after step S2 or S3, and the step S4 is discharging: the materials are stacked to a material storage area through a discharging assembly 5;

s41 pressure feeding and discharging: the discharging conveying mechanism 52 conveys the finished product materials to a bag stacking mechanism 53;

s42 bag folding: the bag stacking mechanism 53 stacks the finished material in the discharge area.
