[0011] The technical scheme provided in the embodiments of the present application has at least the following technical effects:

[0012] The packaging bag processing method provided by the present application first detects the input outer layer printing scheme and inner layer printing scheme, and controls the printing device to print one side of the packaging roll to obtain a printed layer based on the outer layer printing scheme and controls the printing device to print one side of another packaging roll to obtain a packaging layer based on the inner layer printing scheme. In this step, the packaging bag is divided into two layers and printed separately to obtain a printed layer and a packaging layer, which can make the inner and outer layers of the packaging bag have different properties and serve as the basis for the subsequent double-sided die cutting step. Then, the glue application scheme is detected, and the printing surface of the printed layer or the packaging layer is positioned and glued on the opposite side based on the glue application scheme. In this step, the opposite side of the printing surface of the printed layer or the packaging layer is selected as the gluing surface and positioned and glued, which can select different gluing schemes to expand the opening scheme of the packaging bag.

In this method, the printed layer and the packaging layer are compounded into a compound layer which is double-sided die cut into an openable label, without subsequent addition of a label and opening. The function of repeated opening can be completed during the production of the packaging bag, reducing the processing steps of the existing opening and repeated pasting packaging bag processing method, and solving the problems of multiple processing steps and processing difficulty in the existing opening and repeated pasting packaging bag processing method.

[0038] In the description of the application, the reference "one embodiment" or "some embodiments" and the like means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in additional some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0039] In the related art, the existing opening repeated pasting packaging bag needs to be processed into a packaging bag first, and then the opening is opened on the packaging bag and the label is installed at the opening. The opening is closed and opened by pasting and opening the label, which has the problems of many processing steps and processing trouble.

[0040] To solve the above problems, the embodiment of the present application provides a packaging bag processing method. First, the input outer printing scheme and inner printing scheme are detected, and based on the outer printing scheme, the printing device is controlled to print one side of a packaging web to obtain a printing layer, and based on the inner printing scheme, the printing device is controlled to print one side of another packaging web to obtain a packaging layer. In this step, the packaging bag is divided into two layers and printed separately, and the printing layer and the packaging layer are obtained, so that the inner and outer layers of the packaging bag have different properties, and the subsequent double-sided die cutting step is based on this. Subsequently, the input glue coating scheme is detected, and based on the glue coating scheme, the glue coating device is controlled to position and coat the opposite side of the printing surface of the printing layer or the packaging layer. In this step, the opposite side of the printing surface of the printing layer or the packaging layer is selected as the glue coating surface and is positioned and coated, so that different glue coating schemes can be selected to expand the opening scheme of the packaging bag. Then, the composite device is controlled to composite the opposite sides of the printing surfaces of the printing layer and the packaging layer to obtain a composite layer. In this step, the printing layer and the packaging layer are composited to obtain a composite layer, and the rudiment of the packaging bag is preliminarily obtained. Then, the input die cutting scheme is detected, and based on the die cutting scheme, the die cutting device is controlled to die cut the composite layer to obtain a die cut composite layer. In this step, the composite layer is die cut on both sides, so that the composite layer can be die cut into a label, without subsequent opening and pasting of the label, and the processing steps of the existing opening and repeated pasting packaging bag processing method are reduced. Finally, the cutting and edge sealing device is controlled to cut the die cut composite layer according to the predetermined size, and the edge is sealed to obtain an openable packaging bag. In this method, the composite layer composed of the printing layer and the packaging layer is die cut on both sides to obtain an openable label, without subsequent addition of the label and opening. In the process of producing the packaging bag, the repeatable opening function can be completed, the processing steps of the existing opening and repeated pasting packaging bag processing method are reduced, and the problems of the existing opening and repeated pasting packaging bag processing method, such as many processing steps and processing troubles, are solved.

[0041] The packaging bag processing method provided by the embodiment of the present application can be applied to a packaging bag processing device, and at this time, the packaging bag processing device is the execution subject of the packaging bag processing method provided by the embodiment of the present application, and the specific type of the packaging bag processing device is not limited in the embodiment of the present application.

[0042] For example, the packaging bag processing equipment can include a printing device, a gluing device, a laminating device, a die-cutting device, a slitting and edging device, and a control device in communication connection with the printing device, the gluing device, the laminating device, the die-cuting device, and the slitting and edging device. The printing device can be a digital printer, the gluing device can be an automatic dispensing machine, the laminating device can be various laminating machines, the die-cutting device can be various die-cutting machines, and the slitting and edging device can be various edging machines. The control device can control the printing device to perform different printing schemes on the printing layer and the packaging layer, control the gluing device to perform different gluing schemes on the printing layer and the packaging layer, control the laminating device to laminate the printing layer and the packaging layer to obtain a laminated layer, control the die-cutting device to perform die-cutting on the laminated layer, and control the slitting and edging device to perform slitting and edging on the laminated layer after die-cutting.

[0043] The control device can be a single-chip microcomputer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a desktop computer, a computing device, or other processing devices connected to a wireless modem.

[0044] In order to better understand the packaging bag processing method provided by the embodiments of the present application, the specific implementation process of the packaging bag processing method provided by the embodiments of the present application is exemplarily introduced below.

[0045] Figure 1 A schematic flowchart of the packaging bag processing method provided by the embodiments of the present application is shown, and the packaging bag processing method includes:

[0046] S100, detecting an input outer layer printing scheme and an inner layer printing scheme, and controlling a printing device to print one side of a packaging web to obtain a printing layer based on the outer layer printing scheme and to print one side of another packaging web to obtain a packaging layer based on the inner layer printing scheme. The outer layer printing scheme and the inner layer printing scheme are used to instruct the printing device to print, the printing device is used to print a pattern or a barrier layer on the packaging web, the printing layer is used to print an outer layer packaging pattern, and the packaging layer is used to contact and isolate a product.

[0047] It can be understood that the outer layer printing scheme can be a preset outer layer printing pattern, the printing layer refers to the outer layer, and PET, PE, PA, etc. can be used as the packaging web of the printing layer; the inner layer printing scheme can be an inner layer watermark or no pattern, and the packaging layer refers to the inner layer, and PET, PE, aluminum foil, etc. can be used as the packaging web of the packaging layer.

[0048] In this way, the inner and outer layers of the packaging bag can have different properties, such as using PA material for the outer layer to effectively improve the toughness of the packaging bag, and using PE material for the inner layer to effectively ensure food safety.

[0049] S200, detecting an input glueing scheme, and controlling the glueing device to positionally glue the reverse side of the printing surface of the printing layer or the packaging layer based on the glueing scheme. The glueing scheme is used to instruct the glueing device to perform glueing, and the glueing device is used to apply adhesive glue on the printing layer or the packaging layer.

[0050] It can be understood that the reverse side of the printing surface of the printing layer or the packaging layer is selected for glueing, and the reverse side of the printing surface of the printing layer and the packaging layer can also be simultaneously glued (when simultaneously gluing, the printing layer and the packaging layer glueing scheme is an axisymmetric relationship). Positional glueing can adopt different glueing schemes to achieve different packaging bag opening positions. The difference of different glueing schemes is reflected in the type and glueing position of the applied adhesive glue.

[0051] In this way, different openable packaging bags can be adapted to, and different packaging bag opening position schemes can be achieved.

[0052] In one possible implementation, in step S200, the glueing device is controlled to positionally glue the reverse side of the printing surface of the printing layer or the packaging layer based on the glueing scheme, including:

[0053] S210, dividing the reverse side of the printing surface of the printing layer or the packaging layer into a first station and a second station based on the glueing scheme. The first station refers to a processing station for bonding the printing layer and the packaging layer, and the second station refers to a processing station for enabling the packaging bag to be opened.

[0054] It can be understood that the reverse side of the printing surface of the printing layer or the packaging layer is selected as the glueing surface, and the glueing surface is then divided into a first station and a second station. The first station refers to a conventional glueing position in the packaging bag, which is used to bond the printing layer and the packaging layer. The second station refers to a glueing position for labeling in the packaging bag, which is used for opening and repeated opening and pasting of the packaging bag after opening.

[0055] For example, as shown in Figure 2 , the plane shown in Figure 2 is the glueing surface, Figure 2 in which 11 is the first station, Figure 2 12 and 13 are both the second station, and the packaging bag using this glueing scheme will include two repeatable pasting openings.

[0056] In this way, this step can initially achieve a no-label open and repeatable pasting packaging bag.

[0057] S220, controlling the glueing device to apply a first adhesive glue at the first station. The first adhesive glue refers to a glue that cannot be repeatedly bonded.

[0058] It can be understood that the first station is a conventional gluing position, and thus the first adhesive is applied, which can be various non-reusable adhesives, such as epoxy adhesives and the like.

[0059] In this way, the conventional gluing position of the packaging bag can be tightly bonded to the printing layer and the packaging layer.

[0060] S230, controlling the gluing device to apply the second adhesive at the second station. The second adhesive refers to a reusable adhesive.

[0061] It can be understood that the second station is a gluing position for labeling, and thus the second adhesive is applied, which can be various reusable adhesives, such as silicone and the like.

[0062] In this way, the gluing position for labeling of the packaging bag can be repeatedly bonded to serve as labeling.

[0063] Optionally, S231, within the range of a packaging bag size of the packaging web, the second station is a single-communication area, the first station is a single-hole area, and the second station is located in the single hole of the first station.

[0064] It can be understood that within the range of a packaging bag size, the second station can be a single-communication area, the first station can be a single-hole area, and the second station is located in the single hole of the first station, at which time there is only one opening on a single- openable packaging bag. For example, Figure 3 as shown in Figure 3 21 is the first station, and 22 is the second station.

[0065] In this way, the simplest gluing scheme of a single-openable packaging bag with two gluing stations is shown.

[0066] Optionally, in step S200, based on the gluing scheme, the gluing device is controlled to position and glue the opposite side of the printing surface of the printing layer or the packaging layer, further comprising:

[0067] S240, based on the gluing scheme, the opposite side of the printing surface of the printing layer or the packaging layer is divided into a first station, a second station and a third station. The first station refers to a processing station for bonding the printing layer and the packaging layer, the second station refers to a processing station for enabling the packaging bag to be opened, and the third station refers to a processing station for bonding the printing layer and the packaging layer and having a supporting effect to facilitate repeated opening of the packaging bag.

[0068] It can be understood that because the composite layer lacks rigidity and is easily bent and wrinkled, which can cause misalignment between the upper and lower layers in the second station, after the gluing surface is selected, the gluing surface is divided into the first station, the second station and the third station, which is similar to step S210, the difference is that the third station refers to the hard gluing position in the packaging bag. The hard gluing position is used to play a hard supporting role on the basis of bonding the printing layer and the packaging layer, so the third station borders the first station and the second station at the same time.

[0069] Exemplarily, as shown in Figure 4 , Figure 4 The first station 31, the second station 32 and the third station 33 are used. The outer opening of the packaging bag using this gluing scheme is the upper semicircle of the second station 32, and the inner opening is the lower semicircle of the second station 32. The third station 33 plays a hard supporting role.

[0070] In this way, the hard support makes the second station as a label naturally fit without misalignment caused by the soft composite layer.

[0071] S250, control the gluing device to coat the first adhesive in the first station. Wherein, the first adhesive refers to the non-reusable adhesive.

[0072] It can be understood that the first station is a conventional gluing position, so the first adhesive is coated, which can be various non-reusable adhesives such as epoxy adhesives and the like, which is the same as step S220.

[0073] In this way, it is ensured that the conventional gluing position of the packaging bag can tightly bond the printing layer and the packaging layer.

[0074] S260, control the gluing device to coat the second adhesive in the second station. Wherein, the second adhesive refers to the reusable adhesive.

[0075] It can be understood that the second station is a gluing position as a label, so the second adhesive is coated, which can be various reusable adhesives such as silicone and the like, which is the same as step S230.

[0076] In this way, it is ensured that the gluing position as a label of the packaging bag can be repeatedly bonded to play the role of a label.

[0077] S270, control the gluing device to coat the third adhesive in the third station. Wherein, the third adhesive refers to the adhesive whose rigidity is greater than a preset threshold after solidification and is not reusable.

[0078] It can be understood that the third station is a hard gluing position, and therefore the third adhesive is applied, which can be various structural adhesives such as epoxy structural adhesives and the like, or the first adhesive with an increment can be used to play a hard supporting role with a high thickness of the first adhesive.

[0079] In this way, the plastic of the third station can play a hard supporting role.

[0080] Optionally, S271, within the range of a packaging bag size, the second station is a single-communication area, the first station and the third station are single-hole areas, the second station is located in the single hole of the third station, and the third station is located in the single hole of the first station.

[0081] It can be understood that within the range of a packaging bag size, the second station can be a single-communication area, the first station and the third station can be single-hole areas, the second station is located in the single hole of the third station, and the third station is located in the single hole of the first station. At this time, the second station and the third station are located in the single hole of the first station, at this time, there is only one opening on a openable packaging bag, for example Figure 5 as shown in Figure 5 41 is the first station, 42 is the second station, and 43 is the third station Figure 5 (shaded area in the figure), at this time, the third station 43 corresponds to a mechanical limiting structure, making the repeated opening function of the openable packaging bag more stable.

[0082] In this way, a gluing scheme of an openable packaging bag with a three-station gluing scheme with a hard supporting role is shown.

[0083] S300, control the composite device to composite the opposite side of the printing surface of the printing layer and the packaging layer to obtain a composite layer. The composite device is used to align and composite the printing layer and the packaging layer.

[0084] It can be understood that when there is no pattern or no directional pattern in the packaging layer (the directional pattern refers to a pattern arranged at a specific position), the composite device does not need to align the printing layer and the packaging layer left and right, but only needs to align the printing layer and the packaging layer up and down before composite, when the packaging layer includes a directional pattern, it needs to be aligned left and right, up and down at the same time before composite, which can be achieved by setting special laser labels (special laser labels can reflect special frequency laser) on the printing layer and the packaging layer, when the special frequency laser emitted by the laser device is vertically incident on the printing layer and the packaging layer, the reflected laser of the special frequency laser is detected to realize the alignment of left and right, up and down at the same time.

[0085] In this way, the efficiency and accuracy of the composite process are improved.

[0086] S400, detecting an input die-cutting scheme, and controlling the die-cutting device to die-cut the composite layer based on the die-cutting scheme to obtain a die-cut composite layer. The die-cutting scheme is used to instruct the die-cutting device to die-cut, and the die-cutting device is used to die-cut the composite layer. Double-sided die-cutting includes die-cutting the printing layer and not die-cutting the packaging layer, or die-cutting the packaging layer and not die-cutting the printing layer.

[0087] It can be understood that the composite layer is a double-layer structure, and double-sided die-cutting refers to die-cutting the two layers of the composite layer respectively. After double-sided die-cutting according to the die-cutting scheme, the composite layer at the second station can be separated and repeatedly bonded, at which time the composite layer at the second station is equivalent to a label, so the die-cutting scheme is related to the gluing scheme, such as the die-cutting track of the die-cutting scheme can be the edge line of the second station in the gluing scheme.

[0088] In this way, the die-cut composite layer can be opened and repeatedly bonded, and has the function of a label.

[0089] In one possible implementation, in step S400, the die-cutting device is controlled to die-cut the composite layer based on the die-cutting scheme to obtain a die-cut composite layer, including

[0090] S410, obtaining a first track and a second track based on the die-cutting scheme. The first track refers to a part of the edge line of the second station, and the second track refers to another part of the edge line of the second station. The first track and the second track have no intersection.

[0091] It can be understood that the die-cutting scheme can be the edge line of the second station in the gluing scheme, and the die-cutting scheme is double-sided die-cutting. Therefore, the die-cutting scheme can include the first track and the second track, and the two tracks are the die-cutting tracks of the two sides of the double-sided die-cutting. Because the first track and the second track are the inner and outer opening tracks of the packaging bag, the first track and the second track cannot coincide, and if they coincide, a part of the label will be suspended (neither connected to the printing layer nor connected to the packaging layer).

[0092] In this way, the opening of the packaging bag can be more reasonable.

[0093] S420, die-cutting the composite layer along the first track to obtain a first die-cut composite layer. The first die-cutting refers to one side die-cutting operation in the double-sided die-cutting, which can die-cut one side of the composite layer and not die-cut the other side.

[0094] It can be understood that the first side die cutting can be die cutting the printing layer or the packaging layer, the die cutting track is the first track, the first track is part of the edge line of the second station, and the first track is continuous. If the first side die cutting is die cutting the printing layer, the first track is the outer opening track of the packaging bag on the printing layer, and if the first side die cutting is die cutting the packaging layer, the first track is the inner opening track of the packaging bag on the packaging layer, so that the first track is exactly half of the edge line of the second station, and the second track is the other half of the edge line of the second station, so that the inner and outer opening tracks of the packaging bag are more uniform.

[0095] In this way, the opening of the packaging bag is more reasonable.

[0096] S430, the second side die cutting of the composite layer is performed along the second track to obtain a die-cut composite layer. The second side die cutting refers to the other side die cutting operation in the double-side die cutting, which can die cut one side of the composite layer and not die cut the other side, and the die cutting side is opposite to that of the first side die cutting.

[0097] It can be understood that the object of the second side die cutting is opposite to that of the first side die cutting, the die cutting track of the second side die cutting is the second track, if the first track is on the printing layer, the second track is on the packaging layer; if the first track is on the packaging layer, the second track is on the printing layer, and the first track and the second track are different continuous line segments of the edge line of the second station respectively, there is no intersection between the first track and the second track, the length of the first track plus the length of the second track is less than or equal to the length of the edge line of the second station, and the die-cut composite layer is obtained after the double-side die cutting is performed.

[0098] In this way, the opening of the packaging bag is more reasonable.

[0099] Optionally, S421, the second station is a half ring, one of the first track and the second track is the outer circle of the half ring, and the other is the inner circle of the half ring.
