Description

Technical Field

[0001] This application relates to the technical field of logistics auxiliary equipment, and in particular to a privacy protection label and printing device and a printing method thereof. Background Technology

[0002] Currently, self-adhesive labels are the most commonly used on express delivery waybills. Self-adhesive labels consist of three parts: release paper, face paper, and adhesive that bonds the two together. The release paper, commonly known as the "backing paper," has an oily surface and acts as a barrier against the adhesive, thus serving as the substrate for the face paper to ensure it can be easily peeled off. The face paper carries the printed content and is categorized by material, including coated paper, thermal paper, PET, and PVC. The adhesive is applied to the back of the face paper, ensuring both adequate adhesion between the back paper and face paper, and strong adhesion to the object being labeled after the face paper is peeled off.

[0003] Using the aforementioned waybills, after the waybills are attached to the surface of the cardboard box or plastic bag, it is inconvenient for customers to peel them off, which can easily lead to the leakage of customer privacy. Even if the waybill is peeled off, it still needs to be destroyed, otherwise there is still a possibility of leakage of privacy information. Summary of the Invention

[0004] The purpose of this application is to provide a privacy protection label and printing device, as well as a printing method thereof, that facilitate privacy protection.

[0005] Firstly, the privacy protection label provided in this application adopts the following technical solution:

[0006] A privacy protection label includes an attachment layer and several label layers. The label layers are disposed on the attachment layer, and the several label layers are arranged at intervals along the length of the attachment layer. Each label layer includes an information layer and an adhesive layer. The information layer includes a first printing layer, which is adhered to the adhesive layer on one side along its thickness direction, and a second printing layer is disposed on the other side. The adhesive layer is adhered to both the first printing layer and the attachment layer on both sides along its thickness direction. Both the first printing layer and the second printing layer are capable of printing information, and the second printing layer is made of a transparent material.

[0007] By adopting the above technical solution, the attachment layer can support the label layer, thereby facilitating the roll-up of the label layer.

[0008] The label layer includes an adhesive layer and an information layer. The adhesive layer allows the information layer to adhere to the attachment layer, facilitating bonding between the label and the attachment layer. Simultaneously, when using the label, the adhesive layer also allows the information layer to be attached to the corresponding package or other location. The information layer includes a first printing layer and a second printing layer, both capable of printing information. The second printing layer is made of a transparent material and is positioned above the first printing layer. The information printed on the first and second printing layers can overlap and be combined to form complete information. Because the second printing layer is not bonded to the first printing layer, it can be easily peeled off. When the second printing layer is peeled off, the information on both the first and second printing layers is incomplete, thus protecting customer privacy.

[0009] Optionally, the first printing layer has a connecting portion on one side along the length direction of the attachment layer, and the connecting portion is connected to the first printing layer and the second printing layer on opposite sides respectively.

[0010] By adopting the above technical solution, the connection part connects the first printing layer and the second printing layer to each other, and also enables the second printing layer to be flipped with the connection part as the central axis; thus, after the second printing layer is flipped, it can be printed directly along the length direction of the attachment layer on the first printing layer and the second printing layer in sequence, so that the label can be printed in one go.

[0011] Optionally, the connecting portion is provided with a cutting line, the length direction of which is along the width direction of the attachment layer.

[0012] By adopting the above technical solution, the cutting line on the connecting part makes it easy to tear the first printing layer and the second printing layer apart; when the label is stuck on items such as express parcels, the second printing layer can be quickly torn off through the cutting line, thereby protecting customer privacy.

[0013] Optionally, an auxiliary adhesive portion is provided on one side of the adhesive layer along the length direction of the attachment layer, and the auxiliary adhesive portion is provided on the side of the first printed layer away from the connecting portion; when the second printed layer is folded toward the first printed layer, the side of the second printed layer away from the connecting portion adheres to the auxiliary adhesive portion.

[0014] By adopting the above technical solution and setting the auxiliary adhesive part, after the second printing layer is flipped onto the first printing layer, the second printing layer can adhere to the auxiliary adhesive part, which can increase the stability of the second printing layer after the label is attached to the express package and reduce the possibility of the second printing layer falling off due to friction or other reasons during the transportation of the express package.

[0015] Optionally, the adhesive layer has supporting adhesive portions spaced apart on one side along the length direction of the attachment layer; when the second printing layer is folded to be flush with the first printing layer, the supporting adhesive portions are respectively adhered to the second printing layer and the attachment layer on both sides along their own thickness direction.

[0016] By adopting the above technical solution, the setting of the support adhesive part enables the support adhesive part to fix the second printing layer before the label is printed, so that the second printing layer can be flush with the first printing layer, which facilitates the printing of information.

[0017] Optionally, the adhesive layer is provided with superimposed adhesive blocks on both sides along the length direction of the attachment layer, and the superimposed adhesive blocks are respectively adhered to the second printing layer and the attachment layer on both sides along their own thickness direction.

[0018] By adopting the above technical solution and setting the superimposed adhesive block, after the second printing layer is adhered to the superimposed adhesive block, both the second printing layer and the first printing layer are connected to the adhesive layer, and there is no mutual adhesion between the second printing layer and the first printing layer. This allows the second printing layer to be attached to the surface of the first printing layer, and also makes it easy to peel the second printing layer off the first printing layer.

[0019] Optionally, a plurality of printing through holes are provided through the second printing layer.

[0020] By adopting the above technical solution, since printing through holes are opened on the second printing layer, printing can be performed directly after the first printing layer and the second printing layer are superimposed. At this time, some information will be printed on the second printing layer, and other information will be printed on the first printing layer through the printing through holes, so that the label can be formed in one printing after the first printing layer and the second printing layer are superimposed.

[0021] Secondly, the printing device provided in this application adopts the following technical solution:

[0022] A printing device for printing the aforementioned privacy protection label includes a housing, within which a printing production line is disposed. The printing production line includes a thermal printhead, an unwind roller, a conveyor roller assembly, and a feed roller. The housing has a paper outlet for feeding the printed label out of the housing. Several conveyor roller assemblies are arranged along the conveying direction of the printing production line. Each conveyor roller assembly includes a first conveyor roller and a second conveyor roller, the first and second conveyor rollers being axially parallel to each other. Both the first and second conveyor rollers are rotatably connected to the inner wall of the housing, and their outer surfaces abut against each other. The unwind roller is parallel to both the first and second conveyor rollers and the feed roller, and a driving component is coaxially disposed on both the feed roller and the unwind roller. The thermal printhead faces the surface of the conveyed tape within the printing production line. The feed roller is disposed on the side of the thermal printhead near the paper outlet.

[0023] By adopting the above technical solution, the internal printing production line realizes the entire process of label printing from unwinding to printing to finished product delivery. The printing production line includes unwinding and delivery rollers, each equipped with a drive mechanism, enabling the unwinding of the tape and the final discharge process. The thermal printhead enables the printing of information on the first and second printing layers. The conveyor roller assembly guides and limits the conveying direction of the tape.

[0024] Thirdly, the printing method provided in this application adopts the following technical solution:

[0025] A printing method for printing information on the aforementioned privacy protection label includes the following steps: S1: Receiving information: transmitting printing information to a printing device; S2: Information processing: dividing the privacy information to be printed into two parts; S3: Information printing: S31: First layer information printing: printing the first part of the privacy information on a first printing layer; S32: Second layer information printing: printing the second part of the privacy information on a second printing layer; S4: Information integration: bonding the second printing layer with the first printing layer to complete the splicing of the first part of the privacy information and the second part of the privacy information.

[0026] By adopting the above technical solution, privacy information is divided into two parts and printed separately on the first and second printing layers. The complete information can only be displayed after the first and second printing layers are superimposed. Therefore, as long as the second printing layer is damaged, the customer's privacy can be protected.

[0027] Optionally, each specific piece of information in the privacy information to be printed can be divided into two separate parts.

[0028] By adopting the above technical solution, no complete private information is left on the first printing layer and the second printing layer. This ensures that after the second printing layer is separated from the first printing layer, no useful private information is left on either the first or second printing layer, thereby improving the confidentiality of customer information.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The information layer within the label is divided into a first printing layer and a second printing layer. This ensures that the complete information can only be displayed after the first and second printing layers are superimposed. Furthermore, since the first and second printing layers are not directly adhered, they can be easily separated. This ensures that any residual information on the first printing layer or the independent second printing layer on the express package will not leak the customer's privacy information, thereby improving the privacy of customer information.

[0031] 2. The first and second printing layers are connected by a folding mechanism, allowing for continuous printing of the first and second printing layers and facilitating rapid label printing.

[0032] 3. During the label printing process, the required printing information is divided into two parts, so that the information in both parts is incomplete. This makes it impossible to read any complete privacy information on either the first or second printing layer, thus protecting the privacy of customer information. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0042] Example 1:

[0043] A privacy protection label, as referenced Figure 1 The system includes an attachment layer 1 and several label layers 2, all of which are disposed on the attachment layer 1. The label layers 2 are arranged at intervals along the length of the attachment layer 1. Each label layer 2 includes an information layer 21 and an adhesive layer 22. The adhesive layer 22 is adhered to the information layer 21 on one side and to the attachment layer 1 on the other side along its thickness direction. The attachment layer 1 is a long, rolled release film, thus serving as a carrier for the label layers 2, allowing the labels to be rolled up for easy use.

[0044] Reference Figure 1 The label layer 2 includes a first printing layer 211 and a second printing layer 212. Both the first printing layer 211 and the second printing layer 212 are made of thermal paper. The first printing layer 211 is made of white opaque material, and the second printing layer 212 is made of transparent material. The first printing layer 211 is bonded to the second printing layer 212 and the adhesive layer 22 on both sides along its own thickness direction. The first printing layer 211 and the adhesive layer 22 are bonded to each other. Thus, when the first printing layer 211 and the second printing layer 212 are bonded to each other, the printed information on the first printing layer 211 can be spliced ​​together with the printed information on the second printing layer 212 to form complete privacy information.

[0045] Reference Figure 1 and Figure 2A connecting portion 214 is provided on one side of the first printing layer 211 along the length direction of the attachment layer 1. The connecting portion 214 connects the first printing layer 211 and the second printing layer 212 to each other on opposite sides. Thus, before printing information, the second printing layer 212 is flipped with the connecting portion 214 as the central axis, so that the second printing layer 212 can be flipped to be flush with the first printing layer 211. At this time, the first printing layer 211 and the second printing layer 212 are connected to each other along the length direction of the attachment layer 1 and are flush with each other. Therefore, when the first printing layer 211 and the second printing layer 212, which are in a flat state, are fed into the printing device, information can be printed on the surfaces of the first printing layer 211 and the second printing layer 212 at one time. At the same time, after the information is printed, the second printing layer 212 can be folded towards the first printing layer 211 so that the first printing layer 211 and the second printing layer 212 overlap. At this time, some privacy information on the first printing layer 211 can be spliced ​​together with some privacy information on the second printing layer 212 to form complete privacy information.

[0046] An auxiliary adhesive portion 221 is provided on one side of the adhesive layer 22 along the length of the attachment layer 1. The auxiliary adhesive portion 221 is provided along the length of the attachment layer 1 on the side of the first printed layer 211 away from the connecting portion 214. So when the second printed layer 212 is folded onto the first printed layer 211, the end of the second printed layer 212 away from the connecting portion 214 will stick to the auxiliary adhesive portion 221, thereby increasing the stability of the second printed layer 212 after it is bonded to the first printed layer 211.

[0047] Reference Figure 1 and Figure 2 A supporting adhesive portion 222 is provided on the side of the adhesive layer 22 away from the auxiliary adhesive portion 221 along the length direction of the adhesion layer 1. The supporting adhesive portion 222 is spaced apart from the adhesive layer 22 along the length direction of the adhesion layer 1. When the first printing layer 211 is flipped to be flush with the second printing layer 212, the side of the second printing layer 212 away from the first printing layer 211 adheres to the supporting adhesive portion 222. Thus, the supporting adhesive portion 222 can fix the second printing layer 212 before printing, preventing the second printing layer 212 from shifting during the printing process and causing poor printing results.

[0048] Reference Figure 1 and Figure 2 A cutting line 213 is provided on the connecting part 214. The length direction of the cutting line 213 extends through the entire connecting part 214 along the width direction of the attachment layer 1. The cutting line 213 facilitates the tearing of the first printing layer 211 and the second printing layer 212.

[0049] The implementation principle of this application embodiment is as follows: both the first printing layer 211 and the second printing layer 212 can print some privacy information. Since the adhesive layer 22 is set on the first printing layer 211, the first printing layer 211 can be firmly adhered to the express package, which is not easy to tear off or damage.

[0050] Since the first printing layer 211 and the second printing layer 212 are flush with each other and connected to each other along the length of the attachment layer 1, the first printing layer 211 and the second printing layer 212 can be directly used in ordinary thermal printers for information printing. After the information printing is completed, when the second printing layer 212 is folded over the first printing layer 211, since the second printing layer 212 is made of transparent material, the printed information on the second printing layer 212 can be spliced ​​with the printed information on the first printing layer 211. At this time, the first printing layer 211 and the second printing layer 212 can be spliced ​​together to form complete privacy information.

[0051] Since the first printing layer 211 and the second printing layer 212 are not bonded together by the adhesive layer 22, the second printing layer 212 can be easily peeled off from the first printing layer 211, leaving only the first printing layer 211. Therefore, the privacy information remaining on either the peeled second printing layer 212 or the first printing layer 211 is incomplete.

[0052] A printing device, reference Figure 3 It includes a housing 3, and a printing production line 4 is provided inside the housing 3. The printing production line 4 includes a thermal printhead 41, an unwinding roller 42, a conveying roller group 43, and an output roller 44.

[0053] The unwinding roller 42 is axially arranged in the horizontal direction and both ends of the unwinding roller 42 are rotatably connected to the inner wall of the outer casing 3. A driving component is coaxially connected to the unwinding roller 42, and the driving component can be a motor. The unwinding roller 42 can fix the label roll. By driving the unwinding roller 42 to rotate through the driving component, the label roll can be unwound, so as to realize the automatic feeding of the printing equipment.

[0054] Several conveyor roller groups 43 are arranged sequentially along the unwinding direction of the label roll. The conveyor roller group 43 includes a first conveyor roller and a second conveyor roller. The first conveyor roller and the second conveyor roller are axially parallel to each other and are both arranged parallel to the unwinding roller 42. Both ends of the first conveyor roller and the second conveyor roller are rotatably connected to the inner wall of the outer casing 3. The periphery of the first conveyor roller and the periphery of the second conveyor roller are in contact with each other. When the label roll is fed into the first conveyor roller and the second conveyor roller, the first conveyor roller and the second conveyor roller can assist in the conveying of the label.

[0055] The thermal printhead 41 is set vertically and is positioned directly opposite the unwound label, thus enabling the thermal printhead 41 to print information on the label.

[0056] The outer casing 3 has a paper outlet 45. The feed roller 44 is located on the side of the thermal print head 41 near the paper outlet 45, and the feed roller 44 is axially parallel to the unwind roller 42. The feed roller 44 is coaxially connected to a drive unit, which is a motor. An auxiliary roller is located on one side of the feed roller 44. The auxiliary roller is axially parallel to the feed roller 44, and both ends of the auxiliary roller are rotatably connected to the inner wall of the outer casing. The outer side of the auxiliary roller abuts against the outer side of the feed roller 44. The motor drives the feed roller 44 to rotate, which can move the label and also feed the label out of the paper outlet 45.

[0057] The implementation principle of this application embodiment is as follows: the setting of the printing production line 4 inside the outer casing 3 realizes automatic label feeding, conveying, printing and discharging. This meets the printing requirements of privacy protection labels.

[0058] A printing method includes the following steps:

[0059] S1: Information Reception: Transmits the information to be printed to the printing device.

[0060] S2: Information Processing: Process the information to be printed, dividing the privacy information into two parts. Furthermore, each specific piece of information within the privacy information is independently divided into two parts.

[0061] S3: Information Printing: The privacy protection label is fed into the printing device, and information is printed on the privacy protection label at the same time.

[0062] S31: The privacy protection label is delivered inside the printing device, the first printing layer 211 is delivered to the thermal print head 41, and the first part of the privacy information is printed on the first printing layer 211.

[0063] S32: Continue to deliver the privacy protection label, deliver the second printing layer 212 to the thermal print head 41, and print the second part of the privacy information onto the second printing layer 212.

[0064] S4: Information Integration: Fold the second printed layer 212 of the delivered privacy-protected note toward the first printed layer 211 so that the second printed layer 212 adheres to the first printed layer 211. At this time, the privacy information of the first part on the first printed layer 211 and the privacy information of the second part on the second printed layer 212 can be completely combined.

[0065] The implementation principle of this application embodiment is as follows: privacy information can be directly printed on the privacy protection label using common printing equipment. Part of the information is printed on the first printing layer 211, and part of the information is printed on the second printing layer 212. When the second printing layer 212 and the first printing layer 211 are attached to each other, the information on the first printing layer 211 and the corresponding information on the second printing layer 212 are completely spliced ​​together, and the customer's information can be read in this case.

[0066] This printing method ensures that the information on the first printing layer 211 and the second printing layer 212 can be matched, guaranteeing the integrity of the information on the waybill attached to the express package. At the same time, after the second printing layer 212 is torn off, since the printed information on the second printing layer 212 and the printed information on the first printing layer 211 are both incomplete, it is difficult to obtain the customer's privacy information unless both the first printing layer 211 and the second printing layer 212 are obtained at the same time.

[0067] Example 2:

[0068] A privacy protection label, as referenced Figure 4 The difference between this embodiment and Embodiment 1 is that: On both sides of the adhesive layer 22 along the length of the attachment layer 1, there are superimposed adhesive blocks 223. These superimposed adhesive blocks 223 are located outside the first printing layer 211, and are respectively adhered to the second printing layer 212 and the attachment layer 1 on both sides along their thickness direction. Thus, the first printing layer 211 and the second printing layer 212 are independently configured, capable of independent printing, and can then be bonded together by the superimposed adhesive blocks 223.

[0069] The implementation principle of this application embodiment is as follows: information is printed simultaneously on the first printing layer 211 and the second printing layer 212, and the first printing layer 211 and the second printing layer 212 are output simultaneously. After output, the first printing layer 211 is glued to the corresponding express package; while the corresponding second printing layer 212 is superimposed on the first printing layer 211 by superimposing adhesive block 223.

[0070] A printing device, reference Figure 5 The difference between this embodiment and embodiment 1 is that there are two printing production lines 4 inside the outer casing 3, and the two printing production lines 4 are spaced apart in the vertical direction and arranged parallel to each other.

[0071] The implementation principle of this application embodiment is as follows: a printing production line 4 is used for printing information on the first printing layer 211.

[0072] Another printing production line 4 is used for printing information on the second printing layer 212. When the information on the first printing layer 211 is printed and conveyed out of the outer shell 3, the information on the second printing layer 212 is printed simultaneously and conveyed out of the outer shell 3 simultaneously. At this time, the second printing layer 212 is glued to the corresponding first printing layer 211, thus completing the printing.

[0073] A printing method, the difference between this embodiment and embodiment 1 is:

[0074] S3: Information printing. Privacy protection labels are fed into the printing equipment, and information is printed on the privacy protection labels at the same time.

[0075] S31: Print out some privacy information on the first printed layer 211 using a printing device, and then send the printed first printed layer 211 out of the printing device.

[0076] S32: Print another portion of the privacy information on the second printing layer 212 using another printing device, and then send the printed second printing layer 212 to the printing device.

[0077] S4: Information Integration: The printed second printed layer 212 is attached to the corresponding first printed layer 211. At this time, the privacy information of the first part on the first printed layer 211 and the privacy information of the second part on the second printed layer 212 can be completely combined.

[0078] The implementation principle of this application embodiment is as follows: The first printing layer 211 and the second printing layer 212 are printed independently, and after printing, the first printing layer 211 and the corresponding second printing layer 212 are adhered together. This ensures that the information on the first printing layer 211 and the second printing layer 212 can match each other, guaranteeing the integrity of the information on the waybill affixed to the express package. Simultaneously, after the second printing layer 212 is removed, since both the printed information on the second printing layer 212 and the printed information on the first printing layer 211 are incomplete, it is difficult to obtain the customer's privacy information unless both the first printing layer 211 and the second printing layer 212 are obtained simultaneously.

[0079] Example 3:

[0080] A privacy protection label, referring to Figure 6, differs from Embodiment 2 in that: a plurality of printing through holes 224 are provided through the second printing layer 212.

[0081] The implementation principle of this application embodiment is as follows: by setting the printing through hole 224, the first printing layer 211 and the second printing layer 212 can be superimposed on each other, and then the superimposed first printing layer 211 and the second printing layer 212 are sent into a commonly used thermal printer for printing. Part of the information can be printed on the second printing layer 212, and the other part of the information is printed on the first printing layer 211 through the printing through hole 224, so that all the information can be printed at once.

[0082] A printing device, reference Figure 7 The difference between this embodiment and embodiment 2 is that: there is only one printing production line 4 inside the outer casing 3, and there are two unwinding rollers 42, namely the first printing layer unwinding roller 421 and the second printing layer unwinding roller 422. The printing production line 4 is also equipped with a pressing roller group 46; the first printing layer unwinding roller 421 is rotatably connected to the outer casing 3 at both ends in the axial direction and is equipped with a driver; the second printing layer unwinding roller 422 is rotatably connected to the outer casing 3 at both ends in the axial direction and is also coaxially equipped with a driver; the first printing layer unwinding roller 421 and the second printing layer unwinding roller 422 are arranged parallel to each other and spaced apart from each other, so that the first printing layer unwinding roller 421 can realize the unwinding of the first printing layer 211 and the attachment layer 1, and the second printing layer unwinding roller 422 can realize the unwinding of the second printing layer 212.

[0083] The first printing layer unloading roller 421 and the second printing layer unloading roller 422 are arranged vertically at intervals. The pressing roller group 46 is arranged horizontally between the unwinding roller 42 and the first printing layer unloading roller 421. The pressing roller group 46 includes two pressing rollers that abut against each other in the vertical direction. The pressing rollers are arranged axially parallel to the first printing layer unloading roller 421, and both ends of the pressing rollers are rotatably connected to the inner wall of the outer shell 3.

[0084] The implementation principle of this application embodiment is as follows: by cooperating with the pressing roller group 46 and the unwinding roller 42 in the printing production line 4, the material strip released by the first printing layer unwinding roller 421 and the second printing layer unwinding roller 422 can be fed into the pressing roller group 46 to achieve pressing, so as to obtain the superimposed first printing layer 211 and second printing layer 212. Then, information is printed on the pressed material strip, so that part of the information is printed on the second printing layer 212, while the remaining part of the information can be printed on the first printing layer 211 through the printing through hole 224.

[0085] A printing method, the difference between this embodiment and embodiment 2 is:

[0086] S1: Information Reception: Transmits the information to be printed to the printing device.

[0087] S2: Information Processing: Process the information to be printed, dividing the privacy information into two parts. Furthermore, each specific piece of information within the privacy information is independently divided into two parts.

[0088] S3: Information integration: Now the second printing layer 212 is attached to the first printing layer 211.

[0089] S4: Information printing: The first printing layer 211 and the second printing layer 212 after lamination are sent into the printing device, and privacy information is printed on the first printing layer 211 and the second printing layer 212 after lamination.

[0090] The implementation principle of this application embodiment is as follows: the first printing layer 211 and the second printing layer 212 are bonded together, and then the bonded first printing layer 211 and the second printing layer 212 are printed. Partial information can be printed on the second printing layer 212. Through the printing through hole 224, the print head can print partial information on the first printing layer 211, so that the information on the first printing layer 211 and the second printing layer 212 can match each other, ensuring the integrity of the information on the waybill attached to the express package. This printing method does not require high positioning accuracy between the first printing layer 211 and the second printing layer 212, so that the printed information on the first printing layer 211 and the second printing layer 212 can be aligned, ensuring the accuracy of the information.
