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 single-layer bags, double bags or single-layer and double-layer plastic films, and double-layer bagging bags are selected for working procedure examples.

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

S20, preparation of raw materials: the two-layer sleeved raw material bags are selected to be stacked together, and the raw material bags are placed in the material adjusting space 123 by the first alignment material state adjusting device 13 to wait for operation.

S21, opening the bag: and the edges of two sides of the bag mouth are picked up by the first material state adjusting device 13, the first material state adjusting device 13 respectively grabs the edges of each layer of the bag mouth of the double-layer sleeved raw material bag, and then the first material state adjusting device 13 displaces to open the bag mouth.

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

S24, two sections are put into bags: the side support workpiece 143 stretches into the bag mouth under the drive of the adjusting and shifting mechanism 142, at the moment, the material outer bag is adsorbed by the first material state adjusting device 13, the bag mouth is in an open state, the inner film is adsorbed by the side support workpiece 143 and is in a tightening state, the relative positions of the material outer bag and the bag mouth of the inner film are adjusted through the stretching action of the side support workpiece 143 to the bag mouth, the distance between the bag mouth of the inner film and the bag mouth of the outer bag is adjusted, and the effect that the stretching amount of the bag mouth of the inner film stretching out of the bag mouth of the outer bag is adjustable is achieved, so that preparation is made for the next shaping work.

S26, outer shaping: the shaping device 12 presses the material onto the adjusting workpiece 141 for shaping, and the shaping device 12 can be a heat sealing device, such as a heat sealing knife, an ultrasonic spot ironing machine, or a gluing and sewing machine, wherein the heat sealing knife is used for example, and the shaping device 12 performs synchronous hot pressing actions towards the direction of the bag mouth of the raw material bag at two sides of the bag mouth of the raw material bag during heat sealing; the adjusting workpiece 141 is located at the center of the heat sealing area when being pressed and heated after extending into the raw material bag mouth, and the adjusting workpiece 141 has two working and setting modes, one is the pressure receiving part which is arranged flush with the center of the heat sealing area, and the adjusting workpiece 141 directly extends into the bag mouth to be matched with the shaping device 12 for shaping the bag mouth, and the other is that the initial position of the adjusting workpiece 141 cannot be arranged at the position flush with the center of the heat sealing area due to the limited station space, so that the adjusting workpiece 141 needs to be displaced before shaping the bag mouth by the shaping device 12 or synchronously with the shaping work of the shaping device 12, so that the adjusting workpiece 141 can be pressed and shaped at the center of the heat sealing area, otherwise, the device is easy to damage and malfunction, the shaped product is easy to be shaped transition on one side, and the shaping effect is easy to be bad on the other side.

S26, resetting and sending: and the second material state adjusting device 14 is reset, and the material bag is conveyed to 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 to complete the relative position adjustment of the edges of the openings between the material bags under the driving of the adjusting and shifting mechanism 142, the side supporting workpiece 143 adsorbs the inner bag of the raw material, at this time, the outer bag of the raw material is positioned by the first material state adjusting device 13, that is, the inner bag and the outer bag of the raw material are respectively grasped by the two devices, then the two shaping devices perform relative displacement, where the negative pressure mechanism 143 moves, the first material state adjusting device 13 is not moved, and the relative displacement is generated between the two devices to adjust the distance between the two bags, where the extension amount or the extension amount of the edges of the openings can be specifically determined according to the actual working condition.

The step S24 and the step S26 also comprise the step S24-1 of expanding the transverse struts: the side support workpiece 143 stretches out and draws back the action along adjusting workpiece 141 place plane under the drive of opening actuating mechanism 144, prop the bag body to the flattening, let side support workpiece 143 carry out the stull action in adjusting workpiece 141 both sides here, can prop the bag body that overlaps together to the flattening state, and still can solve the fold that causes when snatching the material owing to material state adjusting device one 13, and carry out vacuum adsorption back negative pressure mechanism 143 removal and fix a position the inside and outside bag first, then carry out the side support, the inner bag that the negative pressure mechanism 143 removed the bag mouth that causes its side behind the vacuum adsorption is piled up near the sack, cause the inner bag fold in the sack region, the action that will pile up fold part through adsorbing back is no longer in the sack and has been put the bag body department below the sack, so help the sack to remain the flattening, also help the inner membrane bag can have more allowances when carrying out the packing, reduce the circumstances of inner membrane bag damage, and if in addition, in the department of sack department, the shaping device 12 is located at the sack, can not take place the shaping device, can take place the negative pressure effect in the shaping device, the rate can be reduced, the negative pressure can not take place the shaping device is carried out the shaping device, then the negative pressure efficiency is reduced, the appearance can be partly carried out the shaping, the shaping device is moved, the negative pressure can be avoided.

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 is used to replace the first side supporting workpiece 143 and the opening driving mechanism 144, in the step S22, the adjusting workpiece 141 extends between the inner bags of the opened double-layer pocket, and the first side supporting workpiece 145 also enters the inner bags, and because the first side supporting workpiece 145 has the elastic workpiece with the convex arc, the first side supporting workpiece 145 tightens the inner bags while the adjusting workpiece 141 enters the inner bags, so as to achieve the effect that the transverse supporting of the step S23 can be achieved.

When the adjustment work 141 is not flush with the center of the heat seal area, the step S25 of lowering and shaping is further included between the steps S24-1 and S26: the adjusting workpiece 141 is driven by the adjusting displacement mechanism 142 to move along with the setting device 12 arranged on one side to the setting device 12 arranged on the other side, and the setting devices 12 arranged on both sides of the material state adjusting device II 14 simultaneously press the material on the adjusting workpiece 141.

When the double-layer bagging is required to be folded after finishing shaping at the processing assembly 1, the folding of the bag mouth can be finished through the following steps:

S3, edge folding: the raw material bag is folded into or out of the bag through the folding assembly 2.

S31, opening a section of bag: the material positioning mechanisms 222 clamp materials or start negative pressure suction, the material positioning mechanisms 222 do mutual distance motion, the bag opening is opened, and the opening amplitude is smaller than the maximum opening quantity of the bag opening.

S32, folding the edges of the bag openings: 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 is determined according to the current working condition, and the folding mode is exemplified by folding the bag body.

S34 combined with stretching: after the folding mechanism 221 folds into the bag body, the edge of the bag mouth of the raw material bag folds into the bag body to form an unshaped folded structure, and at this time, the coupler 26 is driven by the radial displacement mechanism 24 to extend into the working space 223.

S35 closure binding: when the combiner 26 stretches into the working space 223 in the bag mouth, the structure of the bag mouth edge folding is aligned, the axial edge folding mechanism 22 performs closing action, and at the moment, the axial edge folding mechanism 22 presses the unshaped bag mouth edge folding structure on the combiner 26 to combine and fix materials; the advantage of doing so is that compared with the shaping modes in other directions, the shaping mode can improve the yield and the attractive appearance and firmness degree after shaping.

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

Step S33 may be added between steps S32 and S34, where step S33 is that the material positioning mechanism 222 opens the two sections of the bag mouth: the material positioning mechanism 222 opens the bag mouth for the second time, the opening amplitude is larger than that of the step S31 or the opening amplitude is larger than the maximum bag mouth, so that two side edges of the two sides of the raw material bag mouth, which are not folded or are not folded completely, can be tensioned and straightened, the side edges of the bag mouth can be changed into a folded state along with the folding structure of the bag mouth, the side edges are tensioned and straightened, and when the bag mouth edges are combined in the next step, the edges of the bag mouth edges, particularly the edges of the double-layer bag mouth overlapping sleeve, can be combined in a flat state, so that the combined effect can be ensured, and the requirement of the yield is met.

In step S35, the axial hemming mechanism 22 performs a synchronous closing action with respect to the combiner 26, the synchronous closing action is to perform a closing action with respect to the axial hemming mechanism 22, and meanwhile, the radial hemming mechanism 25 performs an opening action along an axial direction of the rotating shaft 22131, where the moment of the radial hemming mechanism 25 to the opening of the raw material bag is important, if the opening is late, the radial mechanism 25 either collides with the axial hemming mechanism 22 or the opening cannot be kept in a flat state for combination, if the opening is performed before the axial hemming mechanism 22, the opening is easily flattened, so that the opening hemming structure is easily attached to the combiner 26 in advance, the combination time is excessively long, the product is left, when the radial hemming mechanism 25 performs the opening transverse stretching action, if the opening is not completely folded, the radial hemming mechanism 25 can completely hem the opening side through the opening transverse stretching action, and the radial hemming mechanism 25 and the combiner 26 are stretched in a synchronous manner, so that the synchronous operation is easier.

In step S36, after resetting the devices, the material positioning mechanism 222 is closed, the material positioning mechanism 222 stops positioning after being closed, and the material positioning mechanism 222 stops positioning and then resets and opens. Because when the combiner 26 combines the raw material bags or the material positioning mechanism 222 performs positioning work when grabbing the materials, the materials can generate physical deformation or thermal deformation, especially in some cases, such as the influence of working environment, the materials can be adhered to the combiner 26, and the like, so that the defective rate is easy to rise, and the problem that the material positioning mechanism 222 performs one-time pressing on the raw material bag opening can be solved, and the materials can be kept in a flat state after being processed.

In order to save the labor consumption of raw material feeding, centering and the like, a step S1 centering feeding can be added before the step S2: the raw material bag to be folded is placed on the feeding workbench 41, and is conveyed to the next station through the feeding conveying mechanism 43 and/or the material conveying assembly 3, and the working procedures can be flexibly adjusted according to the working space and the processing requirement, and the step of setting up the feeding working procedure before the step of S2 by the step of S1 is exemplified.

In step S1, before the feeding and conveying mechanism 43 conveys the raw material bag to the next station, the feeding and adjusting positioning mechanism 42 is matched to adjust the angle of the raw material bag entering the feeding assembly 4, the operator places the raw material bag at the starting position of the feeding and conveying mechanism 43, then the feeding and conveying mechanism 43 conveys the raw material bag to the feeding and adjusting positioning mechanism 42, at this time, the feeding and adjusting positioning mechanism 42 can generate a gear action on the raw material bag, the feeding and conveying mechanism 43 continuously conveys the raw material bag until the side edge of the raw material bag is adjusted to be perpendicular to the feeding direction, and the feeding and conveying mechanism 43 and/or the material conveying assembly 3 conveys the raw material bag to the next station.

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

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

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

The S26 outside shaping may also be: the material pressing device in the shaping device presses the material on the first shaping structure for shaping.

S26, outer shaping can be performed: the material pressing device 162 in the driving of the material state adjusting device I13 presses the material on the shaping structure I161 for shaping.
