Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a label peeling device for peeling the backing paper from the face paper of label printing paper. Background Technology

[0002] Label peelers are a common optional module for industrial barcode printers, with two main application scenarios: standalone and embedded. Standalone applications are used in production lines and other locations where manual labeling is required. After printing labels, the printer uses a label peeler to separate the face paper from the backing paper, allowing manual removal and affixing of the label to the electronic product or its packaging. Embedded applications involve embedding the printer into automated equipment such as labeling machines. After printing labels, the printer uses a peeler to separate the face paper from the backing paper, and automated equipment such as a labeling arm removes the label and affixes it to the electronic product or its packaging.

[0003] The application scenarios for the two types of label peelers described above have different requirements for their structure and other aspects. In standalone applications, to ensure good coordination between the machine and manual operation, a paper detection mechanism needs to be installed below the paper output of the label peeler to identify whether the peeled label paper has been manually removed. Only after the paper detection mechanism detects that the previous label has been removed can the printer execute the printing and peeling action for the next label; otherwise, the adhesive labels will stick together and become unusable. In embedded applications, the automated equipment needs to communicate with the printer in real time, sending the printing instructions and content to the printer. The printer, in conjunction with the peeling module, performs the printing and peeling actions, outputting the paper to the paper output port, where it is then picked up by the labeling arm and other equipment for application. Normally, the labeling arm has a label detection component, eliminating the need for an additional paper detection mechanism on the peeler.

[0004] In both of these applications, embedded applications, especially in vertical labeling, require the label peeling device to be positioned at the peeler's exit point (i.e., the peeling point of the peeling blade) to ensure versatility and simplify the structure and operation of the labeling arm and other label-taking devices. This necessitates that all related structures on the peeler, such as the peeling roller, the closing hook, and the opening handle, be designed inside the peeling point on the peeling blade to avoid interfering with the normal movement of the labeling arm. In stand-alone applications, the paper-taking detection structure must be designed outside the peeling point to detect the presence of a label after the peeling point.

[0005] The above-mentioned different requirements normally require the design of two different peelers, which are manufactured and sold separately according to different applications; or in embedded applications, a lateral movement structure is added to the label picking device to avoid the peeler panel. Summary of the Invention

[0006] Based on the above-mentioned technical problems, the purpose of this application is to provide a label peeler that simultaneously meets the needs of both stand-alone and embedded applications.

[0007] To achieve the above objectives, this application provides a label peeler suitable for use in a barcode printer. The label peeler includes: a peeling inner support assembly configured to be switchably mounted on a mounting bracket between an open position and a closed position, and including an inner support and a peeling roller; when the peeling inner support assembly is held in the closed position and viewed from a direction along the axis of the peeling roller, the peeling inner support assembly is located inside the peeling point; a peeling blade configured to create a turning angle on the backing paper of the label printing paper as it passes through, the peeling blade defining a label peeling point; and an outer panel assembly detachably mounted to the... The outer panel assembly includes an inner peeling support assembly; the outer panel assembly includes an outer panel and a paper pick-up detection device mounted on the outer panel; the outer panel assembly is configured to expose the label peeling point when attached to the inner peeling support assembly, so that the user can manually remove the label paper peeled off from the label peeling point; the paper pick-up detection device is configured to communicate with the printer's control board to identify whether the peeled label paper has been removed from the label peeling point; when the outer panel assembly is attached to the inner peeling support assembly and viewed from the direction along the axis of the peeling roller, the paper pick-up detection device is located outside the peeling point.

[0008] The label peeler in this case can be combined to meet the needs of both standalone and embedded applications. Its components are universal, which significantly reduces manufacturing costs.

[0009] In some specific embodiments of the above technical solutions, the label peeler further includes: a mounting bracket, which is fixedly mounted to the barcode printer, and the inner peeling bracket assembly is rotatably connected to the mounting bracket between an open position and a closed position; viewed from the direction along the axis of the peeling roller, the mounting bracket is located inside the peeling point.

[0010] In some specific embodiments of the above technical solutions, the inner support peeling assembly includes an inner cover handle for the user to manually switch the inner support peeling assembly from the closed position to the open position, and the outer panel assembly includes an outer cover handle; the outer cover handle is configured to engage with the inner cover handle when the outer panel assembly is attached to the inner support peeling assembly, thereby replacing the inner cover handle for the user to manually perform the operation of switching the inner support peeling assembly from the closed position to the open position.

[0011] In some specific embodiments of the above technical solutions, the inner support has an outer surface extending in the vertical direction, and the inner opening handle does not protrude from the outer surface in the lateral direction.

[0012] In some specific embodiments of the above technical solutions, the peelable inner support assembly includes a cover retaining mechanism; the cover retaining mechanism includes a cover hook; the cover hook is configured to engage with the mounting bracket to hold the peelable inner support assembly in the cover position.

[0013] In some specific embodiments of the above technical solutions, the peeling blade is configured to be mounted on the mounting bracket, and the mounting bracket, the peeling inner bracket assembly, and the peeling blade constitute a pre-assembled integral module.

[0014] In some specific embodiments of the above technical solutions, the outer panel assembly and the stripped inner support assembly are connected by a number of threaded fasteners.

[0015] In some specific embodiments of the above technical solutions, anti-sticking ribs are provided on the outer panel.

[0016] In this case, by adding anti-sticking ribs, the long label face paper is prevented from bending down and sticking to the outer panel, making it difficult to remove.

[0017] In some specific embodiments of the above technical solutions, the peeling inner support assembly includes an inner auxiliary pressure roller; in terms of the running direction of the bottom paper of the label printing paper, the inner auxiliary pressure roller is located downstream of the label peeling point; the inner auxiliary pressure roller is mounted on the inner support and is configured to adjust the running trajectory of the label printing paper after passing the label peeling point.

[0018] In this case, by adding an inner auxiliary pressure roller to press against the passing bottom paper, the turning angle of the label printing paper at the peeling knife is reduced. A smaller turning angle can effectively promote the separation of the bottom paper and the face paper of the label printing paper, thereby improving the peeling ability of the label peeler.

[0019] In some specific embodiments of the above technical solutions, the label peeler further includes: an external auxiliary pressure roller assembly, which is detachably mounted on the outer outer panel and includes an external auxiliary pressure roller; the external auxiliary pressure roller is located upstream of the label peeling point in terms of the running direction of the bottom paper of the label printing paper; the external auxiliary pressure roller is configured to adjust the running trajectory of the label printing paper that is about to pass through the label peeling point.

[0020] The external auxiliary pressure roller assembly in this case is used to further adjust the turning angle of the paper running trajectory at the peeling knife, further optimizing the peeling performance. In some application scenarios where special materials such as synthetic paper and silver paper are used, or for labels with extremely small heights, there are higher requirements for the peeling ability of the peeler.

[0021] In some specific embodiments of the above technical solutions, the external auxiliary pressure roller assembly includes an external support roller; in terms of the running direction of the bottom paper of the label printing paper, the external support roller is located downstream of the label peeling point; the external support roller is configured to support the peeled label paper from below.

[0022] This invention places the mounting bracket and the peeling inner bracket assembly inside the label peeling point, which allows embedded labeling arms and other automated components to directly press down to perform the labeling action after picking up the label, without the need for extra lateral displacement. This simplifies the structural design of the automated equipment, reduces the manufacturing cost of the equipment, and makes the peeling device more versatile.

[0023] In some specific embodiments of the above technical solutions, the peeling blade is configured as a roller bracket that can be mounted to the barcode printer.

[0024] Other advantages of the embodiments of this application will be further explained in the following description. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this application will now be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] See Figure 1 and Figure 2 This illustrates a label peeler 100. The label peeler 100 can be used as a barcode printer 900 (see...). Figure 9 The label peeler 100 can be used as an optional accessory. It can be used in both embedded applications where labeling is performed by automated equipment such as labeling arms and stand-alone applications where labeling is performed manually.

[0028] The label peeler 100 mainly includes a mounting bracket 1, an inner peeling bracket assembly 2, an outer panel assembly 3, a rotating shaft 4, a peeling blade 5, and an outer auxiliary pressure roller assembly 6. The mounting bracket 1 provides support and secures the label peeler 100 to components such as the rubber roller bracket of a barcode printer. The inner peeling bracket assembly 2 is rotatably mounted on the mounting bracket 1 via the rotating shaft 4, allowing it to be rotated between an open and closed position. The outer panel assembly 3 is detachably attached to the inner peeling bracket assembly 2. The peeling blade 5 can be fixed to a suitable position on the printer's rubber roller bracket. The outer auxiliary pressure roller assembly 6 is an optional component, detachably mounted on either the outer panel assembly 3 or the inner peeling bracket assembly 2. In other embodiments, a similar effect is achieved by using a pivot or hinge structure instead of the rotating shaft 4 in this embodiment.

[0029] In some embodiments of this application, the peeling blade 5 is a one-piece bent metal component. The peeling blade 5 defines a label peeling point 50 (i.e., the blade position). The peeling blade 5 is configured to create an effective turning angle on the backing paper of the label printing paper when the label printing paper passes through the label peeling point 50, thereby allowing the label face paper passing through this point to be smoothly peeled off from the label backing paper. A manual operator or an automatic labeling arm can pick up the separated label face paper at the label peeling point 50. In other embodiments, the peeling blade is configured to be mounted to the mounting bracket 1 described below or the inner bracket 21 of the peeling inner bracket assembly 2. In some embodiments, the mounting bracket, the peeling inner bracket assembly, and the peeling blade can form a pre-assembled integral module.

[0030] In some embodiments of this application, the mounting bracket 1 is an integral component, which can be made of a high-strength hard material such as metal.

[0031] The peeling inner support assembly 2 includes an inner support 21, a peeling roller 22 mounted on the inner support 21, a pressure spring 23, a cover retaining mechanism 24, an inner cover opening handle 25, and an inner auxiliary pressure roller 26. A torsion spring 41 is provided at the position of the rotating shaft 4 on the inner support 21 and the mounting bracket 1 (see...). Figure 4 ) The peeling roller 22 is located inside the inner support 21. When the inner support assembly 2 is in operation, the peeling roller 22, under the action of the compression spring 23, clamps the label backing paper after peeling the label face paper between the peeling roller 22 and the printer's printing roller (or backing paper traction roller). The peeling roller 22 and the printer's printing roller (or backing paper traction roller) work together to form a label backing paper traction system, providing backing paper traction force for label peeling.

[0032] The lid-closing retaining mechanism 24 is disposed inside the inner support 11 and includes a lid-closing hook 241, a hook pivot 242, and a hook torsion spring 241. The lid-closing hook 241 cooperates with the mounting bracket 1 to fix the peeled inner support assembly 2 in the working position after the lid is closed. In other embodiments of this application, the lid-closing hook 241 can be omitted and replaced by other types of lid-closing retaining mechanisms, as long as the lid-closing retaining mechanism can satisfy the requirement of holding the peeled inner support assembly 2 in the closed position.

[0033] An inner cover handle 25 is located at the opening 211 in the middle of the inner support 21, and is connected to a closing hook 241. The inner cover handle 25 allows the user to manually switch the inner support assembly 2 from the closed position to the open position; when the inner support assembly 2 is in the open position, the operator can perform tasks such as changing label printing paper. In some embodiments of this application, the inner support 21 has an outer surface 212 extending in the vertical direction, and the front end face of the inner cover handle 25 is flush with the outer surface 212 of the inner support 21. This design can prevent the inner cover handle 25 from interfering with automated equipment such as labeling arms.

[0034] An inner auxiliary pressure roller 26 is mounted on an inner support 21 and configured to adjust the trajectory of the backing paper of the label printing paper after passing the label peeling point 50, thereby adjusting the turning angle of the paper's trajectory at the label peeling point 50 and optimizing peeling performance. In terms of the backing paper's direction of travel, the inner auxiliary pressure roller 26 is located downstream of the label peeling point 50. The inner auxiliary pressure roller 26 adjusts the turning angle by pressing against the backing paper of the label printing paper passing through this point; a smaller turning angle effectively promotes the separation of the backing paper from the label face paper, thus improving the peeling capability of the label peeler. In some embodiments of this application, the inner auxiliary pressure roller is a non-essential component and can be omitted.

[0035] See Figure 2 , Figure 3 In some embodiments of this application, the outer panel assembly 3 includes: an outer panel 31, an outer opening cover handle 32, and a paper detection device 33 mounted on the inner side of the outer panel 31.

[0036] The front end face of the outer panel 31 is provided with several anti-sticking ribs 34. The anti-sticking ribs 34 can prevent long label sheets from bending down and sticking to the outer panel 31, making them difficult to remove. The outer opening handle 32 is located in the middle of the outer panel 31. In this embodiment, the outer opening handle 32 and the outer panel 31 are an integral part. The rear end face of the outer panel 31 is provided with threaded holes 35 for mounting the outer panel 31 to the inner bracket 21. During the process of fixing the outer panel assembly 3 to the peeling inner bracket assembly 2, the installer inserts a pair of threaded fasteners (not shown in the figure) into a pair of mounting holes 213 and a pair of threaded holes 35 on the inner bracket 21 to mount the outer panel 31 to the inner bracket 21. When the outer panel assembly 3 is mounted to the peeling inner bracket assembly 2, the label peeling point 50 of the peeling blade 5 can be exposed so as to set up a paper picking detection device 33 to detect whether the peeled sheet has been taken away, and to prevent multiple peeled labels from being ejected at the same time and sticking together.

[0037] In some embodiments of this application, after the outer panel assembly 3 is assembled with the inner support assembly 2, the outer opening handle 32 on the outer panel assembly 3 engages with the inner opening handle 25 on the inner support assembly 2 and achieves linkage. The outer opening handle 32 can replace the inner opening handle 34 for the user to manually perform the operation of switching the inner support assembly 2 from the closed position to the open position.

[0038] See Figure 4When the inner support assembly 2 is in the closed position, viewed from the direction along the axis 221 of the peeling roller 22 (i.e., the observer stands on one side of the peeling roller 22 and looks towards the other side of the axis), both the mounting bracket 1 and the inner support assembly 2 are located inside the label peeling point 50. After the outer panel assembly 3 is connected to the inner support assembly 2, the inner cover handle 25 and the outer cover handle 32 are interlocked; when the user pulls the outer cover handle 32 outward, the pulling force applied to the outer cover handle 32 will be transmitted to the inner cover handle 25 and pull the closing hook 24 to flip away from the mounting bracket 1, and the inner support assembly 2 is switched to the open position.

[0039] In this embodiment, a mounting bracket 1 is fixed to the barcode printer 900, and the inner support assembly 2 is rotatably connected to the mounting bracket 1, allowing the inner support assembly 2 to switch between an open position and a closed position. In other embodiments, the mounting bracket can be omitted, and the inner support assembly can be selectively fixed to the barcode printer through various methods such as plug-in structures, magnetic structures, and detachable fasteners. It is understood that, provided that the inner support assembly can switch between an open position and a closed position, and when the inner support assembly is in the closed position, and when viewed along the axis of the peeling roller, the inner support assembly is located inside the peeling point, the specific connection method between the inner support assembly and the barcode printer does not limit the scope of protection of this invention.

[0040] Continue as Figure 3 As shown, the paper pick-up detection device 33 is fixedly mounted on the inner side of the outer panel 31 by fasteners 8. The outer panel 31 has a detection port 312 located above the paper pick-up detection device 33. The paper pick-up detection device 33 detects whether the label paper has left the detection port 312, that is, whether the label paper has been removed from the peeling point 50. The paper pick-up detection device 33 can communicate with the printer's control board (not shown in the figure) to identify whether the peeled label paper has been removed from the label peeling point 50. Combined with... Figure 4 After the outer panel assembly 3 is attached to the inner support assembly 2, when viewed from the direction along the axis 221 of the peeling roller 22, the paper picking detection device 33 is located outside the peeling point 50.

[0041] The paper detection device 33 can use sensor components such as photoelectric sensors, laser sensors, ultrasonic sensors and sound wave sensors to detect the label paper; in practical applications, the selection, integration and optimization of components need to be carried out according to specific requirements.

[0042] The external auxiliary pressure roller assembly 6 is an optional component, which can be detachably mounted as an integral assembly on the outer panel 31 or the inner support assembly 2. A pair of threaded mounting posts 36 are provided on the inner side of the outer panel 31. In some embodiments of this application, the external auxiliary pressure roller assembly 6 includes a pair of supports 61, an external auxiliary pressure roller 62, and an external support roller 63. Mounting holes 611 are provided on each of the pair of supports 61. The external auxiliary pressure roller assembly 6 can be fixedly attached to the outer panel 3 by inserting a pair of threaded fasteners 8 into the pair of threaded mounting posts 36 and the pair of mounting holes 611.

[0043] An outer auxiliary pressure roller 62 is rotatably supported on a pair of supports 61 about its own axis, and a pressure spring 64 is arranged between the outer auxiliary pressure roller 62 and the pair of supports 61. The outer auxiliary pressure roller 62 is configured to adjust the trajectory of the label printing paper that is about to pass the label peeling point 50. An outer support roller 63 is also rotatably supported on a pair of supports 61 about its own axis, and the outer support roller 63 is configured to support the peeled label paper from below.

[0044] Continue as Figure 4 As shown, in terms of the running direction of the label printing paper, the outer auxiliary pressure roller 62 is located upstream of the label peeling point 50, and the outer support roller 63 is located downstream of the label peeling point 50.

[0045] The external auxiliary pressure roller assembly 6 is used to further adjust the turning angle of the paper running trajectory at the label peeling point 50, further optimizing the peeling performance. In some application scenarios where special materials such as synthetic paper and silver paper are used, or labels with extremely small height are used, there are higher requirements for the peeling ability of the peeler.

[0046] The peeler design mentioned above for barcode printers can be based on the pre-assembly of mounting bracket 1, peeler inner bracket assembly 2, and rotating shaft 4 as a basic assembly 101 (see...). Figure 2 The label peeler 100, when used with the peeling blade 5, is suitable for embedded applications. For standalone use, the outer panel assembly 3 is installed on the basic assembly 101, and the paper feed detection and the printer's pre-installed interface (not shown) are connected to form a complete peeler configuration. In scenarios requiring higher peeling performance, an external auxiliary pressure roller assembly 6 can be added to reduce the peeling angle and improve the peeling capability of the label peeler 100.

[0047] The peeler 100 design of this application allows for the separate manufacture of the peeler base assembly 101 and the outer panel assembly 3, which can then be sold in combination based on demand. This optimizes the manufacturing of the label peeler and the versatility of the parts, eliminating the need to design and manufacture two different peeling solutions.

[0048] The following is in conjunction with the appendix Figure 5-10Let me explain the use of the label peeler 10 in two different application scenarios.

[0049] See Figure 5 , Figure 6 In an embedded application scenario, the label peeler 100 consists of a mounting bracket 1, a peeler base assembly 101 composed of a peeling inner support assembly 2 and a rotating shaft 4, and a peeling blade 5, which are respectively mounted on the rubber roller bracket 601 of the barcode printer 600. Specifically, the mounting bracket 1 and the peeling blade 5 are both mounted on the rubber roller bracket 601, and the cover hook 241 engages with the mounting bracket 1; the peeling inner support assembly 2 is held in the closed position, and the peeling rubber roller 22 is located below the printing rubber roller 602 of the printer 600, and the peeling rubber roller 22 and the lower part of the printing rubber roller 602 abut against each other under the action of the compression spring 23. The label printing paper 700, passing over the printing roller 602 of the barcode printer 600, will move towards the location of the peeling knife 5. After passing the label peeling point 50 of the peeling knife 5, the label printing paper 700 will create a turning angle θ1 on the bottom paper 701 of the label printing paper 700, and the label face paper 702 will be peeled off from the bottom paper 701 of the label printing paper 700, so that automated equipment such as the labeling arm (not shown in the figure) can easily pick up the label face paper 702. The bottom paper 701 of the label printing paper 700 then passes between the inner auxiliary pressure roller 26, the peeling roller 22 and the lower part of the printing roller 602 in sequence, and is recycled to a winding device (not shown in the figure).

[0050] In embedded applications of the label peeler 100, if the label printing paper 700 needs to be replaced, the user only needs to pull the inner cover handle 25 outward to separate the cover hook 241 from the mounting bracket 1 and peel off the inner bracket assembly 2 to enter the open position.

[0051] Furthermore, in this embedded application scenario, since all the structures of the label peeler base assembly 101 after installation are located inside the peeling point 50 on the peeling blade 5, the barcode printer 600 will allow automated equipment such as the labeling arm in embedded applications to directly press down after picking up the label (i.e., Figure 6 The labeling action is performed in the direction of the arrow in the image, without the need for extra lateral displacement. This simplifies the structural design of the automated equipment, reduces the manufacturing cost, and makes the peeling equipment more versatile.

[0052] See Figure 7 , Figure 8In a standalone application scenario, in addition to installing the aforementioned peeler basic assembly 101 on the barcode printer 800, the outer panel assembly 3 is also installed on the inner support 21 of the inner support assembly 2. Specifically, the mounting bracket 1 and the peeling blade 5 are both installed on the rubber roller bracket 801 of the barcode printer 800. The cover latch 241 engages with the mounting bracket 1, the inner support assembly 2 is held in the closed position, the peeling rubber roller 22 is located below the printing rubber roller 802 of the printer 800, and the peeling rubber roller 22 and the lower part of the printing rubber roller 802 abut against each other under the action of the compression spring 23. The outer cover handle 32 is fastened to the inner cover handle 25. The detection port 312 of the paper detection device 33 is connected to the interface (not shown) reserved by the barcode printer 800. The label printing paper 700, passing over the printing roller 802 of the barcode printer 800, moves towards the peeling blade 5. After passing the label peeling point 50 at the very front of the peeling blade 5, the label printing paper 700 creates a turning angle θ2 on the bottom paper 701, allowing the label face paper 702 to be peeled off from the bottom paper 701. The bottom paper 701 then passes sequentially between the inner auxiliary pressure roller 26, the peeling roller 22, and the lower part of the printing roller 702, and is retracted to a winding device (not shown in the figure). The operator can then manually remove the label face paper 702 from the outside of the label peeling point 50. After the label face paper 702 is removed, the paper detection device 33 feeds back the detection result to the control board of the barcode printer 800, thereby notifying the barcode printer 800 to perform the next round of printing and peeling.

[0053] When the label peeler 100 is used in a standalone scenario, if the label printing paper 700 needs to be replaced, the user only needs to pull the outer cover handle 32 outward to separate the cover hook 241 from the mounting bracket 1 and peel off the inner bracket assembly 2 to enter the open cover position.

[0054] In this standalone application scenario, with the help of the paper detection device 33, the barcode printer 600 can coordinate with the operator's manual labeling rhythm to carry out label printing and peeling work in an orderly manner, and there will be no situation where multiple labels stick together at the label peeling point 50 and become unusable.

[0055] See Figure 9 , Figure 10 This also applies to the label peeler 100 in a standalone application scenario, which is relative to... Figure 7 and Figure 8In the label peeler 100 usage state, in addition to installing the peeler base assembly 101 and outer panel assembly 3 on the barcode printer 900, the outer auxiliary pressure roller assembly 6 is also installed together. Specifically: the mounting bracket 1 and the peeling blade 5 are both installed on the rubber roller bracket 901 of the barcode printer 900, and the outer auxiliary pressure roller assembly 6 is installed on the outer panel 31; the cover latch 241 engages with the mounting bracket 1, the inner peeling bracket assembly 2 is held in the closed position, the peeling rubber roller 22 is located below the printing rubber roller 902 of the printer 900, and the peeling rubber roller 22 and the lower part of the printing rubber roller 902 abut against each other under the action of the compression spring 23, the outer cover handle 32 is fastened to the inner cover handle 25; the detection port 312 of the paper detection device 33 is connected to the interface (not shown) reserved by the barcode printer 800. With the help of the external auxiliary pressure roller assembly 6, the label printing paper 700 passes over the upper part of the printing roller 902 of the barcode printer 900 and then passes through the auxiliary pressure roller 62 and the peeling knife 5 in sequence. After the label peeling point 50 at the front end of the peeling knife 5, the label printing paper 700 will create a turning angle θ3 on the bottom paper 701 of the label printing paper 700, so that the label face paper 702 can be peeled off from the bottom paper 701 of the label printing paper 700. The bottom paper 701 of the label printing paper 700 then passes between the inner auxiliary pressure roller 26, the peeling roller 22 and the lower part of the printing roller 902 in sequence, and is recycled to a winding device (not shown in the figure). The operator can manually remove the label face paper 702. After the label face paper 702 is removed, the paper detection device 33 feeds back the detection result to the control board of the barcode printer 900, thereby notifying the barcode printer 900 to perform the next round of printing and peeling.

[0056] In this example, by adding an auxiliary pressure roller assembly 6, the peeling turning angle θ3 is reduced, thereby improving the peeling capacity of the peeler. It is particularly suitable for peeling labels made of special materials such as synthetic paper and silver paper, or for peeling labels with extremely small heights, i.e., application scenarios that require higher peeling capacity from the peeler.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
