Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of labeling device, in particular to an automatic labeling device capable of preventing label breakage. BACKGROUND

[0002] In the field of automatic labeling equipment, the problem of label breakage frequently occurring in the labeling process is one of the key bottlenecks affecting the continuity of production and the stability of equipment.

[0003] Chinese patent CN207985437U discloses a high-speed automatic labeling device, which integrates a pre-labeling device and an active label collecting device that operate synchronously with the labeling engine, thereby reducing the tension fluctuation of the label tape to some extent and reducing the risk of breakage caused by instantaneous overload. Although this structure can improve the labeling speed and reduce the probability of label breakage, it still relies on the label material itself having sufficient tensile strength and physical stability.

[0004] However, in actual industrial applications, the quality of label base paper is uneven, and some inferior materials have uneven fiber distribution or insufficient tensile strength, making it difficult to withstand the continuous tension required in the labeling process. In addition, unsuitable storage or environmental conditions may cause the base paper to become damp and soft or brittle, further weakening its mechanical properties. On the other hand, poor label die-cutting processes such as excessive cutting depth can damage the base paper structure and form potential breaking points, which are prone to breakage under mechanical tension. The existing device lacks real-time sensing and autonomous recovery capabilities for label tape breakage. Once the tape breaks, manual intervention is required for rethreading and system debugging, resulting in production interruption, reduced efficiency, and potential device jamming or misoperation, increasing equipment maintenance costs.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0030] Referring to Figures 1 to 10 As shown in the figure, an automatic labeling device for preventing label tape breakage includes a breakage prevention and repair device installed on the labeling device 1, the breakage prevention and repair device including a limiting installation plate 2, guide rollers 3, a breakage prevention detection device 4, and a quick repair device 5; the limiting installation plate 2 is fixedly installed on the labeling device 1; the guide rollers 3 are provided in multiple numbers, and the guide rollers 3 are rotationally connected with the limiting installation plate 2; the breakage prevention detection device 4 is installed on the limiting installation plate 2, and the breakage prevention detection device 4 includes two detection clamping devices 41 installed on the limiting installation plate 2, a pressure detection head 42 being installed below the detection clamping devices 41, and a multi-section push device 43 for driving the pressure detection head 42 and the detection clamping devices 41 to move; the quick repair device 5 is on the limiting installation plate 2, and the quick repair device 5 is used for repairing the broken label tape.

[0031] The limiting installation plate 2 is installed in a fixed connection manner at a specified position of the labeling device 1, providing a stable installation basis for other components. The guide rollers 3 are provided in plurality and are installed on the limiting installation plate 2 in a rotating connection manner, used for guiding the label tape to move along a predetermined path.

[0032] During the automatic labeling process of the labeling device 1, the label tape starts to move under the pulling action of the labeling device 1. The label tape sequentially passes through the guide rollers 3 and is guided by the guide rollers 3 to move stably to the clamping area of the detection clamping device 41. The label tape will have a short pause when it moves to this area, which provides stable conditions for the subsequent detection operation. Then, the label tape continues to move to the labeling area to complete the labeling work of the labeling device 1, and the continuous labeling is realized in this way.

[0033] When a section of the label tape moves to the clamping areas of the two detection clamping devices 41 and pauses, the multi-section pushing device 43 starts to act. The multi-section pushing device 43 first pushes the detection clamping device 41 to move towards the label tape until the detection clamping device 41 clamps and fixes the label tape, ensuring that the label tape is stable during the detection process and will not move or shake, thereby ensuring the accuracy of the detection result.

[0034] After the detection clamping device 41 clamps and fixes the label tape, the multi-section pushing device 43 continues to act to push the pressure detection head 42 to move towards the fixed label tape. With the movement of the pressure detection head 42, it gradually contacts the surface of the label tape and applies a certain pressure to the surface of the label tape.

[0035] The pressure detection head 42 feeds back the detected pressure data to the control system in real time. If the label tape can withstand the applied pressure, it means that the tensile strength and other physical properties of the label meet the requirements, and it is a qualified label. At this time, the control system controls the multi-section pushing device 43 to drive the pressure detection head 42 and the detection clamping device 41 to reset quickly, and the label tape continues to move normally for subsequent labeling work. If the label tape breaks under the pressure, the pressure data detected by the pressure detection head 42 will change abnormally, and the control system will immediately recognize and determine that it is a breakage fault. At this time, the control system sends an alarm signal and controls the labeling device 1 to pause operation to prevent the fault from expanding.

[0036] After the labeling device 1 pauses operation, the staff uses the quick repair device 5 installed on the limiting installation plate 2 to butt joint and repair the broken area. The quick repair device 5 has the functions of precise positioning and quick connection, and can quickly and accurately butt joint and fix the two ends of the disconnected label tape, ensuring that the connected label tape after repair is firm and smooth.

[0037] After the label tape is repaired, the staff simply debugs the labeling device 1, checks whether the tension of the label tape, the guide path and other parameters return to normal. Through the rapid repair and simple debugging of the labeling device 1, the complex traction debugging process is not needed, and the equipment fault processing time is greatly shortened. After the debugging is completed, the labeling device 1 can continue to run and restore the normal labeling operation.

[0038] Referring to Figures 1 to 6 As shown in the drawings, the detection clamping device 41 comprises a fixed clamping plate 411, a mounting slide rail 412, an anti-skid clamping push plate 413 and a first spring; the mounting slide rail 412 is fixedly installed on the limiting installation plate 2; the fixed clamping plate 411 is horizontally arranged above the label tape, the fixed clamping plate 411 is fixedly connected with one side of the mounting slide rail 412, and the bottom of the fixed clamping plate 411 is provided with a plurality of first sliding rollers 4111; the anti-skid clamping push plate 413 is horizontally arranged directly below the fixed clamping plate 411, and the anti-skid clamping push plate 413 is slidably connected with the mounting slide rail 412; and the first spring is installed between the anti-skid clamping push plate 413 and the mounting slide rail 412.

[0039] The fixed clamping plate 411 is provided with a plurality of first sliding rollers 4111 at the bottom, which can be in contact with the surface of the label tape when the label tape moves, thereby reducing the friction and ensuring smooth movement of the label tape. The anti-skid clamping push plate 413 is horizontally arranged directly below the fixed clamping plate 411 and is slidably connected with the mounting slide rail 412, so as to make linear reciprocating motion along the mounting slide rail 412 under the action of the multi-section pusher 43. The first spring is installed between the anti-skid clamping push plate 413 and the mounting slide rail 412 and is in an initial compression state, thereby providing the anti-skid clamping push plate 413 with elastic support force.

[0040] In the automatic labeling process of the labeling device 1, the label tape starts to move under the pulling action of the labeling device 1. The label tape sequentially passes through the guide rollers 3 and moves stably under the guidance of the guide rollers 3. When a section of the label tape moves to the clamping area of the two detection clamping devices 41, the labeling device 1 pauses the pulling action, so that the label tape is temporarily paused in the area.

[0041] When the label tape is stopped, the multi-stage pushing device 43 is started. The multi-stage pushing device 43 applies a force to push the anti-skid clamping push plate 413, and the anti-skid clamping push plate 413 moves along the mounting slide rail 412 to the fixed clamping plate 411 in the direction of overcoming the elastic resistance of the first spring. With the movement of the anti-skid clamping push plate 413, the anti-skid surface of the anti-skid clamping push plate 413 gradually approaches the label tape and finally tightly presses against the label tape. At this time, the label tape is clamped and fixed between the fixed clamping plate 411 and the anti-skid clamping push plate 413, the first sliding roller 4111 at the bottom of the fixed clamping plate 411 is in contact with the upper surface of the label tape, and the anti-skid surface of the anti-skid clamping push plate 413 is in contact with the lower surface of the label tape, and through the joint action of the two, the position of the label tape is stable during detection and cannot move or shake, which provides a reliable guarantee for subsequent pressure detection.

[0042] After the label tape is clamped and fixed, the pressure detection head 42 moves to the surface of the label tape under the pushing of the multi-stage pushing device 43 and applies a certain pressure for detection. The pressure detection head 42 feeds back the detected pressure data to the control system in real time to determine whether the tensile strength and other physical properties of the label tape meet the requirements. When the pressure detection head 42 completes the detection of the label tape, the multi-stage pushing device 43 quickly changes the direction of the force to drive the pressure detection head 42 and the anti-skid clamping push plate 413 to reset. The anti-skid clamping push plate 413 moves away from the fixed clamping plate 411 along the mounting slide rail 412 under the elastic restoring force of the first spring, and gradually releases the pressure on the label tape. When the anti-skid clamping push plate 413 is completely reset, the label tape is no longer affected by the clamping force and returns to a free state. At this time, the labeling device 1 can continue to pull the label tape to move it to the labeling area to complete the labeling work.

[0043] Referring to Figures 1 to 4 As shown in the figure, the pressure detection head 42 includes a fixed mounting block 421, a mounting bracket 422, a contact roller 423, a rotating shaft 424 and a pressure detector; the fixed mounting block 421 is fixedly installed at the movable end of the multi-stage pushing device 43; the rotating shaft 424 is provided with two, and the rotating shaft 424 is rotatably installed on the fixed mounting block 421; a torsional spring is installed between the rotating shaft 424 and the fixed mounting block 421; the mounting bracket 422 is provided with two and is evenly distributed on the rotating shaft 424, and the mounting bracket 422 is fixedly connected with the rotating shaft 424; the contact roller 423 is provided with two and is evenly distributed on the mounting bracket 422, and the contact roller 423 is rotatably connected with the mounting bracket 422; the pressure detector is installed in the inside of the fixed mounting block 421, and the pressure detector is used for detecting the pressure value of the torsional spring.

[0044] During the operation of the labeling device 1, when the detection clamping device 41 clamps and fixes the label tape, the multi-section pushing device 43 pushes the fixed mounting block 421 to move towards the label tape. Since the fixed mounting block 421 is connected with the mounting bracket 422, the rotating shaft 424 and other components, the entire pressure detection head 42 structure moves towards the label tape. During this process, the abutting roller 423 has not contacted the label tape, and the torsional spring remains in the initial state, and the pressure value detected by the pressure detector is the initial value.

[0045] With the continuous movement of the fixed mounting block 421, the abutting roller 423 gradually contacts the surface of the label tape. When the abutting roller 423 is subjected to the pressure of the label tape, it will cause the mounting bracket 422 to drive the rotating shaft 424 to rotate. When the rotating shaft 424 rotates, the torsional spring is subjected to extrusion, the elastic potential energy increases, and the pressure value changes.

[0046] The pressure detector monitors the change of the pressure value of the torsional spring in real time, and transmits the detection data to the control system. With the continuous pushing of the multi-section pushing device 43, the fixed mounting block 421 further approaches the label tape, the pressure applied by the abutting roller 423 to the label tape gradually increases, and the pressure value of the torsional spring also increases accordingly. When the pressure value of the torsional spring reaches the pre-set threshold value, it indicates that the label tape does not break under the pressure, that is, the tensile strength and other physical properties of the label tape meet the requirements, and it is determined as a qualified label.

[0047] Referring to Figures 1 to 4 As shown in the figure, the multi-section pushing device 43 includes a connecting bracket 431, a movable connecting frame 432, a second spring 433, a rotating drive disc 434, a linkage push rod 435 and a rotating driver; the connecting bracket 431 is fixedly connected with the detection clamping device 41; the movable connecting frame 432 is slidingly installed on the connecting bracket 431, and one end of the movable connecting frame 432 is fixedly connected with the pressure detection head 42; the second spring 433 is installed between the connecting bracket 431 and the movable connecting frame 432; the rotating drive disc 434 is rotatably installed on the limiting mounting plate 2; one end of the linkage push rod 435 is rotatably connected with the rotating drive disc 434, and the other end of the linkage push rod 435 away from the rotating drive disc 434 is rotatably connected with the movable connecting frame 432; the rotating driver is fixedly installed on the limiting mounting plate 2, and the output end of the rotating driver is in transmission connection with the rotating drive disc 434.

[0048] When the labeling device 1 needs to detect the label tape, the rotary driver is started to drive the rotary driving disc 434 to rotate. The rotation of the rotary driving disc 434 drives the linkage push rod 435 to displace, and the linkage push rod 435 pushes the movable connecting frame 432 to slide on the connecting support 431. Since the movable connecting frame 432 is fixedly connected with the pressure detection head 42, the pressure detection head 42 moves synchronously. At the same time, the second spring 433 is elastically deformed by the pushing of the movable connecting frame 432 to generate elastic force. The elastic force of the second spring 433 drives the connecting support 431 to move, and the connecting support 431 is fixedly connected with the detection clamping device 41, thereby driving the anti-slip clamping push plate 413 of the detection clamping device 41 to move. In this process, the anti-slip clamping push plate 413 overcomes the elastic resistance of the first spring and moves towards the fixed clamping plate 411 along the mounting slide rail 412. With the continuous movement of the movable connecting frame 432, the anti-slip clamping push plate 413 continues to move towards the fixed clamping plate 411. When the anti-slip surface of the anti-slip clamping push plate 413 tightly presses against the label tape, the label tape is clamped and fixed between the fixed clamping plate 411 and the anti-slip clamping push plate 413. The anti-slip surface of the anti-slip clamping push plate 413 contacts the lower surface of the label tape, and the anti-slip design ensures that the label tape is stable during detection and does not move or shake, thereby providing a reliable basis for subsequent pressure detection.

[0049] After the label tape is clamped and fixed, the rotary driving disc 434 continues to rotate, and the linkage push rod 435 further pushes the movable connecting frame 432 to rise. The movable connecting frame 432 drives the pressure detection head 42 to continue to move towards the label tape, so that the abutting roller 423 gradually contacts the surface of the label tape. The label tape is subjected to pressure detection.

[0050] Referring to Figures 1 to 3 As shown, the quick repair device 5 includes a broken tape positioning mechanism 51, a double-sided laminator 53, and a tape cutter 52. The broken tape positioning mechanism 51 is installed on the limiting installation plate 2, and is used to position the labeling broken tape position. The tape cutter 52 is fixedly installed on the limiting installation plate 2, and is used to cut the conveying tape 6. The double-sided laminator 53 is connected with the output end of the tape cutter 52, and is used to stably paste the tape 6.

[0051] When the label breakage detection device 4 detects label breakage, the labeling device 1 stops running. The worker operates the breakage positioning mechanism 51 installed on the limiting installation plate 2 to perform alignment positioning operation on both ends of the label breakage, and ensures that the two breakage surfaces of the label are accurately butted with each other, providing an accurate basic position for subsequent repair. After completing the breakage positioning, the worker opens the double-sided laminator 53 and butts with the discharge end of the adhesive tape cutter 52 fixedly installed on the limiting installation plate 2. The adhesive tape cutter 52 transports a fixed length of adhesive tape 6 to the double-sided laminator 53 according to the preset parameters, so as to meet the length requirement of the adhesive tape 6 required for breakage repair. The double-sided laminator 53 fixes the two pieces of adhesive tape 6 transported from the adhesive tape cutter 52 to prevent the adhesive tape 6 from deviating or falling off during movement. Subsequently, the double-sided laminator 53 cooperates with the breakage positioning mechanism 51 to accurately move to the label breakage area that has been aligned and positioned, so as to ensure that the adhesive tape 6 can accurately cover the breakage position.

[0052] When the double-sided laminator 53 moves to the label breakage area, it automatically laminates the two pieces of adhesive tape 6 on the upper and lower surfaces of the label breakage, so that the adhesive tape 6 is closely pasted with the label breakage, realizing the basic connection of the breakage. After completing the lamination of the adhesive tape 6, the worker trims the edges of the adhesive tape 6 laminated on the label using scissors, so that the appearance of the repaired label is flat. Subsequently, the worker resets the components of the quick repair device 5 to prepare for the next repair operation. After the label tape is repaired, the worker performs simple debugging on the labeling device 1 to check whether the tension, guide path and other parameters of the label tape return to normal. After the debugging is completed, the labeling device 1 can continue to run and resume normal labeling operation.

[0053] Referring to Figures 6 to 9 As shown in the figure, the breakage positioning mechanism 51 comprises a horizontal adjustment sliding rail 511 and a sliding clamping assembly 512; the horizontal adjustment sliding rail 511 is fixedly installed on the limiting installation plate 2; the sliding clamping assembly 512 is provided with two, and the sliding clamping assembly 512 is in sliding connection with the horizontal adjustment sliding rail 511; the sliding clamping assembly 512 comprises a sliding installation block 513 slidingly installed in the horizontal adjustment sliding rail 511, a limiting sliding groove is arranged on the sliding installation block 513, a magnetic attraction block is arranged on the side of the sliding installation block 513, a fixed clamping rod 515 is fixedly installed on the side of the sliding installation block 513, a second sliding roller 5151 is arranged on the bottom of the fixed clamping rod 515, a clamping rod 516 is slidingly installed in the limiting sliding groove, a rotating clamping hook 514 is rotatably arranged on the clamping rod 516, and limiting clamping edges 517 are arranged on the sides of the fixed clamping rod 515 and the clamping rod 516.

[0054] When the label breakage detection device 4 detects the label breakage, the labeling device 1 stops running. At this time, the staff starts to operate the breakage positioning mechanism 51 to clamp the two ends of the label breakage respectively. Each sliding clamping assembly 512, the staff rotates the rotating hook 514 on the clamping rod 516, so that the rotating hook 514 and the fixed clamping rod 515 are clamped with each other. Through this clamping mode, the broken label is stably clamped between the fixed clamping rod 515 and the clamping rod 516, which ensures that the label will not be excessively loose in the subsequent operation process. During clamping, the second sliding roller 5151 arranged at the bottom of the fixed clamping rod 515 is in contact with the upper surface of the label tape. When the sliding clamping assembly 512 moves, the second sliding roller 5151 can roll, effectively reducing the friction between the fixed clamping rod 515 and the label tape, and avoiding damage to the label or affecting the clamping effect due to friction.

[0055] After clamping the two ends of the label breakage, the staff pushes the sliding mounting block 513 of the two sliding clamping assemblies 512. Since the sliding mounting block 513 is slidingly mounted in the horizontal adjustment slide rail 511 fixed to the limiting mounting plate 2, the sliding mounting block 513 can move horizontally along the horizontal adjustment slide rail 511. Because the fixed clamping rod 515 and the clamping rod 516 are connected with the sliding mounting block 513, the horizontal movement of the sliding mounting block 513 will drive the fixed clamping rod 515 and the clamping rod 516 to move horizontally synchronously. Synchronous movement can generate a pulling force on the label breakage, so that the label breakage surface remains in a horizontal state, avoiding bending or twisting of the breakage surface, and creating conditions for subsequent accurate alignment of the breakage joint.

[0056] During the process of the sliding mounting blocks 513 of the two sliding clamping assemblies 512 approaching each other, the magnetic force generated by the magnetic attraction block on the side of the sliding mounting block 513 can attract the other group of sliding clamping assemblies 512, facilitating the mutual splicing of the two groups of sliding clamping assemblies 512. Through mutual cooperation, the two sliding clamping assemblies 512 can effectively bring the joints of the two broken label tapes close to each other. The accurate alignment of the two broken label tape joints can be realized, and the connection quality after the breakage repair is ensured.

[0057] The side of the fixed clamping rod 515 and the clamping rod 516 is provided with a limiting clamping edge 517, which provides important positioning support for the subsequent double-sided bonding operation. When the broken label joint is aligned, the double-sided bonding device 53 can rely on these limiting clamping edges 517 to stay at the specified position. The limiting clamping edge 517 can limit the movement range of the double-sided bonding device 53, ensure the accurate position of the double-sided bonding device 53 when bonding the adhesive tape 6, and make the adhesive tape 6 accurately bond at the specified position of the broken label, provide convenient conditions for subsequent use of the double-sided bonding device 53 to bond and repair the broken label, and improve the accuracy and efficiency of the repair.

[0058] Referring to Figures 6 to 8As shown, the output end of the adhesive tape cutter 52 is provided with a docking frame 521, which is fixedly connected with the limiting mounting plate 2, and the docking frame 521 is provided with two sliding insertion strips 522. The adhesive tape cutter 52 is a prior art and will not be described here. The adhesive tape cutter 52 is used to cut a fixed length of adhesive tape 6.

[0059] The adhesive tape cutter 52 is fixedly mounted on the limiting mounting plate 2 to ensure its stability during operation. The output end of the adhesive tape cutter 52 is provided with a docking frame 521, which is also fixedly connected with the limiting mounting plate 2 to provide a stable base platform for docking of the double-sided laminator 53. The docking frame 521 is provided with two sliding insertion strips 522, which are used for precise docking and mounting with the double-sided laminator 53, so that one side of the double-sided laminator 53 can be accurately stopped at the discharge end of the adhesive tape cutter 52, ensuring that the adhesive tape 6 can accurately enter the double-sided laminator 53 when discharged from the adhesive tape cutter 52, and preparing for subsequent adhesive tape 6 lamination operation.

[0060] When the break detection device 4 detects a label break, the labeling device 1 stops running, and the break positioning mechanism 51 completes the alignment and positioning of the label break. At this time, the adhesive tape cutter 52 starts to work according to the preset parameters, and cuts the adhesive tape 6 according to the set length. And the adhesive tape cutter 52 conveys the cut fixed length of adhesive tape 6 to the double-sided laminator 53 which has been docked and mounted. At the same time, the double-sided laminator 53 fixes the entering adhesive tape 6 to prevent the adhesive tape 6 from shifting or falling off during movement, ensuring that the adhesive tape 6 can accurately cover the aligned and positioned label break area.

[0061] Referring to Figures 6 to 10 As shown, the double-sided laminator 53 includes a rotating lamination rail 531, a lamination push block 532, a third spring, and a pressing frame 533. The rotating lamination rail 531 is provided with two ends rotatably connected with each other, and each rotating lamination rail 531 is provided with a docking slot 5312 on the side. The rotating lamination rail 531 is also provided with a limiting rail 5311. The lamination push block 532 is provided with two and evenly distributed on the rotating lamination rail 531, and the lamination push block 532 is slidably connected with the rotating lamination rail 531. The third spring is provided with a plurality of and evenly distributed between the lamination push block 532 and the rotating lamination rail 531. The pressing frame 533 is provided with two and evenly distributed on the rotating lamination rail 531, and the pressing frame 533 is rotatably connected with the rotating lamination rail 531. The pressing frame 533 is provided with a plurality of limiting teeth in the inside.

[0062] When the label breakage detection device 4 detects the label breakage, the labeling device 1 stops running, and the breakage positioning mechanism 51 completes the alignment positioning operation of the label breakage. At this time, the operator starts to operate the double-sided laminator 53, first opens the two rotationally connected rotating lamination rails 531, and rotates and opens the pressing frame 533, so that the pressing frame 533 is separated from the rotating lamination rail 531. Then, the butt joint clamping groove 5312 on both sides of the rotating lamination rail 531 is butt jointed with the sliding insertion strip 522 on the butt joint frame 521 on the output end of the adhesive tape cutter 52, so that the rotating lamination rail 531 is accurately stopped at the discharge end of the adhesive tape cutter 52, and is ready for receiving the adhesive tape 6.

[0063] After the adhesive tape cutter 52 cuts the adhesive tape 6 to a predetermined length according to the preset parameters, the adhesive tape 6 is transported to the rotating lamination rail 531. The limiting rail 5311 arranged on the rotating lamination rail 531 can effectively limit the position of the cut adhesive tape 6, preventing the adhesive tape 6 from shifting during placement. After the adhesive tape 6 is placed, the operator resets the pressing frame 533 so that it is in contact with the rotating lamination rail 531. The multiple limiting teeth arranged inside the pressing frame 533 press the edges of the adhesive tape 6, further ensuring that the adhesive tape 6 is stably stopped inside the limiting rail 5311, avoiding the adhesive tape 6 from falling off or shifting during subsequent operations. The operator places the adhesive tape 6 on the two rotating lamination rails 531 in sequence according to the above steps.

[0064] After the adhesive tape 6 is placed, the operator contacts one rotating lamination rail 531 with the limiting clamping edge 517 of the clamping rod 516 in the sliding clamping assembly 512, and contacts the other rotating lamination rail 531 with the limiting clamping edge 517 of the fixed clamping rod 515. Since the limiting clamping edge 517 is arranged on the side of the fixed clamping rod 515 and the clamping rod 516, and the limiting clamping edge 517 provides important positioning support for the double-sided lamination operation, the double-sided laminator 53 can be accurately stopped at the specified lamination position by this method. After the double-sided laminator 53 is stopped at the specified lamination position, the operator presses the lamination push block 532 uniformly distributed on the rotating lamination rail 531. The lamination push block 532 is in sliding connection with the rotating lamination rail 531, and a plurality of third springs are uniformly distributed between the lamination push block 532 and the rotating lamination rail 531. When the lamination push block 532 is pressed, the lamination push block 532 overcomes the elastic force of the third spring, passes through the limiting rail 5311, and pushes the adhesive tape 6 in the limiting rail 5311 to pass through the pressing frame 533. The adhesive tape 6 can accurately and smoothly laminate with the aligned and positioned label breakage area, achieving accurate and smooth repair of the label breakage.

[0065] Specific working principle:

[0066] In the automatic labeling process of the labeling device 1, the label tape starts to move under the pulling action of the labeling device 1. The label tape passes through the guide roller 3 in sequence and moves stably to the clamping area of the detection clamping device 41 under the guidance of the guide roller 3. The label tape will stop for a short time when it moves to this area, which provides stable conditions for the subsequent detection operation. Then, the label tape continues to move to the labeling area to complete the labeling work of the labeling device 1, and the continuous labeling is realized in this way.

[0067] When a section of the label tape moves to the clamping areas of the two detection clamping devices 41 and stops, the multi-section pushing device 43 starts to work. The multi-section pushing device 43 first pushes the detection clamping device 41 to move towards the label tape until the detection clamping device 41 clamps and fixes the label tape, ensuring that the label tape is stable during the detection process and will not move or shake, thereby ensuring the accuracy of the detection result.

[0068] After the detection clamping device 41 clamps and fixes the label tape, the multi-section pushing device 43 continues to work and pushes the pressure detection head 42 to move towards the fixed label tape. With the movement of the pressure detection head 42, it gradually contacts the surface of the label tape and applies a certain pressure to the surface of the label tape.

[0069] The pressure detection head 42 feeds back the detected pressure data to the control system in real time. If the label tape can withstand the applied pressure, it means that the tensile strength and other physical properties of the label meet the requirements, and it is a qualified label. At this time, the control system controls the multi-section pushing device 43 to drive the pressure detection head 42 and the detection clamping device 41 to reset quickly, and the label tape continues to move normally for subsequent labeling work. If the label tape breaks under the pressure, the pressure data detected by the pressure detection head 42 will change abnormally, and the control system will immediately identify and determine that it is a breakage fault. At this time, the control system sends an alarm signal and controls the labeling device 1 to pause operation to prevent the fault from expanding.

[0070] After the labeling device 1 pauses operation, the worker uses the quick repair device 5 installed on the limiting installation plate 2 to butt joint and repair the broken area. The quick repair device 5 has the functions of precise positioning and quick connection, and can quickly and accurately butt joint and fix the two ends of the broken label tape, ensuring that the connected label tape after repair is firm and smooth.

[0071] After the label tape is repaired, the worker performs a simple debugging on the labeling device 1 to check whether the tension and guide path parameters of the label tape have returned to normal. Through the quick repair and simple debugging of the labeling device 1, the complex traction debugging process is not needed, which greatly shortens the equipment fault handling time. After the debugging is completed, the labeling device 1 can continue to operate and resume the normal labeling work.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
