Description

Technical Field

[0001] This invention relates to the field of beverage bottle labeling technology, specifically a robot-based glass beverage bottle labeling device. Background Technology

[0002] The glass bottle labeling machine achieves precise label positioning and application through the coordinated movement of the drive wheel, labeling wheel, and reel, combined with sensor detection and PLC control. The drive wheel intermittently drags the label tape, which is pulled out from the reel and separated from the backing paper by the label peeling plate (label knife). When the glass bottle reaches the designated position via the conveyor belt, the label tape drive wheel accelerates to match the speed of the conveyor belt, and the labeling wheel presses the label onto the bottle. Then, it decelerates and stops. When labeling glass beverage bottles, the extension speed and extension length of the label can be adjusted via the control panel. When feeding glass beverage bottles, a robot usually clamps and feeds the bottles and places them on the conveyor belt for labeling.

[0003] In existing technology, when labeling glass beverage bottles, the label backing paper passes through a labeling blade. As the winding assembly feeds the backing paper, a section of the label is automatically peeled off. When an infrared sensor detects the glass beverage bottle passing by, the control device pushes the pressure roller to make the bottle contact the label. The rotating roller rotates to apply the label. Because the backing paper and the rotating roller alternate between rotation and stopping, the labeling blade may shift slightly over time. This shift causes the backing paper to move up and down on the side of the labeling blade, resulting in the label tilting on the glass bottle during labeling, affecting the accuracy of the labeling. Furthermore, the labeling blade is fixed to the base plate by two adjustable screws, requiring adjustments to its level. The need to repeatedly adjust two screws makes it difficult to quickly adjust the level of the labeling blade. Furthermore, the labeling blade lacks a component to monitor the label application; workers can only determine if the label is misaligned by observing the label application on the glass bottle. The absence of a misalignment alarm component hinders timely detection and repair of label misalignment, leading to the need for rework and re-labeling of labeled glass bottles, wasting time and reducing the labeling pass rate. When installing the backing paper, the end of the backing paper needs to be clamped to the take-up roller. Current technology typically uses a U-shaped, elastic clip to fix the backing paper, but the clip's high elasticity makes it difficult to move and insert into the slot on the side of the take-up roller, resulting in inconvenient operation. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a robot-based labeling device for glass beverage bottles.

[0005] The technical solution adopted by this invention to solve its technical problem is: a robot-based glass beverage bottle labeling device, including a bracket and a conveying mechanism mounted on the bracket. A guiding mechanism and a pressing mechanism are mounted on the bracket, and an adjusting mechanism is mounted on the guiding mechanism. The guiding mechanism includes a side frame, which is mounted on the bracket. The adjusting mechanism includes a movable opening. The top of the side frame has an inclined movable opening. A rotating seat located at the movable opening is rotatably connected to the side frame. A labeling knife is fixedly connected to the rotating seat. A labeling tool located at the bottom of the movable opening is mounted on the bottom of the side frame. The mounting plate has a mounting bracket fixedly connected to its bottom, and a base plate fixedly connected to its bottom. Two wedge blocks are fixedly connected to the base plate, and a trapezoidal block is slidably connected between the two wedge blocks. A lead screw is horizontally threaded onto one of the wedge blocks, and the lead screw is rotatably connected to the trapezoidal block. Ball bearings are placed on both sides of the trapezoidal block and between the two wedge blocks. Two push rods are symmetrically rotatably connected to the mounting plate about the rotating seat. The bottom of the push rods is rotatably connected to the ball bearings, and the bottom of the push rods abuts against the bottom of the marking tool.

[0006] Specifically, the height of the trapezoidal block is equal to the height of the two wedge blocks, and the side of the trapezoidal block forms an inverted V-shape with the two wedge blocks. One end of the caliper is inclined, and the other end of the caliper has a rectangular structure. The rotating seat is located at the center of the rectangular surface at the bottom of the caliper.

[0007] Specifically, the adjustment mechanism also includes baffles. Two sets of baffles are symmetrically installed on the base plate about the center of the two balls. The length of the baffles is greater than the distance between the wedge block and the trapezoidal block.

[0008] Specifically, the guiding mechanism also includes a placement plate, which is rotatably connected to the side frame. A guide post one and a guide post two are rotatably connected to the side frame. A fixed frame with an inverted L-shaped structure is installed on the side frame. A motor two is installed on the fixed frame. The output end of the motor two is connected to a drive shaft through a coupling.

[0009] Specifically, the conveying mechanism includes a track, a support is mounted on the track, two rollers are rotatably connected on the track, a conveyor belt is mounted on the two rollers, a motor is mounted on the track, the output end of the motor is fixedly connected to one of the rollers through a coupling, the marking knife and drive shaft are located inside the track, and the robot body is mounted on the support.

[0010] Specifically, the pressing mechanism includes a support frame, which is fixedly connected between the track and the bracket. Two cylinders opposite to the drive shaft are installed on the support frame. The extension and retraction ends of the two cylinders are fixedly connected to a fixed frame with a U-shaped structure. Pressure rollers are vertically rotatably connected to the two fixed frames. The drive shaft and the two pressure rollers are arranged in a triangle.

[0011] Specifically, the sniper blade is equipped with an alarm mechanism, which includes a controller and an alarm. The controller is mounted on the mounting bracket, and the alarm is electrically connected to the controller. A mounting base is fixedly connected to the back side of the sniper blade, and a stud is slidably connected to the mounting base. A limit bracket is fixedly connected to the bottom of the mounting base, and a probe fixed to the bottom of the stud is slidably connected to the limit bracket. The probe has a hexagonal prism structure, and a spring is provided on the outer side of the probe. One end of the spring is fixed to the side wall of the probe, and the other end of the spring is fixed to the bottom of the mounting base. A nut that abuts against the mounting base is threaded onto the stud. The probe is electrically connected to the controller.

[0012] Specifically, the alarm mechanism also includes a pressure plate, and the bottom of the probe is fixedly connected to the pressure plate that fits against the side of the blade. The side of the blade is provided with a protrusion corresponding to the pressure plate.

[0013] Specifically, a winding mechanism is installed on the side frame, the winding mechanism includes a drive disk, the drive disk is rotatably connected to the side frame, a motor is installed at the bottom of the side frame, the output end of the motor is keyed to the drive disk, the drive disk has a cross-shaped groove, a winding reel is attached to the drive disk, a cross-shaped reinforcing frame is welded to the bottom of the winding reel, the reinforcing frame engages with the groove on the drive disk, two sliding rods are slidably connected inside the drive disk, a spring is held between the two sliding rods and the drive disk, and inverted L-shaped grippers are welded to the opposite ends of the two sliding rods, the grippers engage with the winding reel, a spool is welded to the center of the surface of the winding reel, and a guide post is rotatably connected to the side frame.

[0014] Specifically, the winding mechanism also includes side grooves. Two arc-shaped side grooves are formed opposite each other on the reel. A middle plate is welded to the top center of the reel. Outer sleeves are welded opposite each other on both sides of the middle plate. Inner shafts are slidably connected inside the two outer sleeves. Springs are held between the two inner shafts and the outer sleeves. Pressure shafts that engage with the side grooves are vertically fixed to the opposite ends of the two inner shafts. Pressure rods are slidably connected to the middle plate. Connecting rods are rotatably connected between the pressure rods and the two pressure shafts. Springs are held between the pressure rods and the middle plate.

[0015] The beneficial effects of this invention are: 1. The robot-based glass beverage bottle labeling device of the present invention has an adjustment mechanism installed on the side frame. When the labeling blade tilts, causing it to become uneven or the labeling to tilt or shift, the screw connected to the horizontal thread on the rotating wedge block drives the trapezoidal block to slide between the two wedge blocks. The ball bearings on both sides of the trapezoidal block roll accordingly, thereby pushing two push rods that are symmetrically connected about the rotating seat to rise and fall. One push rod raises one end of the labeling blade and lowers the other end, and the two ball bearings always contact the wedge block and the trapezoidal block, thereby accurately adjusting the level of the labeling blade. This design ensures the stability and accuracy of the labeling blade level adjustment, effectively avoids the labeling tilting problem caused by small offsets during the backing paper feeding process, and improves the labeling quality.

[0016] 2. The robot-based glass beverage bottle labeling device of the present invention has an alarm mechanism installed on the labeling blade. During the labeling process, if the label position is offset, resulting in inaccurate labeling, the backing paper will push the pressure plate at the bottom of the probe upward, causing the probe displacement to exceed a preset value. At this time, the controller electrically connected to the probe will receive an abnormal signal and immediately trigger the alarm. This timely feedback mechanism allows operators to quickly detect abnormalities in the device's operating status, avoid the continuous offset of the backing paper leading to the production of more unqualified products, and improve the labeling pass rate.

[0017] 3. The robot-based glass beverage bottle labeling device of the present invention has a winding mechanism installed on the side frame. When installing the winding reel, simply pull the two grippers back to back to create installation space, place the winding reel on the drive plate, and make the cross-shaped reinforcing frame at the bottom of the winding reel engage with the cross-shaped groove on the drive plate to achieve initial positioning. Under the pulling force of the second spring, the grippers will retract inward and engage with the winding reel to further fix the winding reel and prevent it from falling off during rotation. The installation method is simple and quick, without complicated operation steps, and it is easy to remove the wound backing paper. When it is necessary to replace the backing paper on the reel, press down the pressure rod that is slidably connected to the middle plate. The pressure rod drives the two pressure shafts to expand outward through the connecting rod, so that the pressure shafts are disengaged from the side groove. At this time, the old backing paper can be removed, the new backing paper can be placed inside the side groove, and then the pressure rod is released. The third spring returns to its original position, and the pressure shafts will re-engage in the side groove to complete the replacement of the new backing paper. The operation is simple and labor-saving, without the need to turn the existing elastic fixing clamp, which improves the efficiency and convenience of replacing the backing paper.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-12As shown, the present invention discloses a robot-based glass beverage bottle labeling device, comprising a support 1 and a conveying mechanism 2 mounted on the support 1. A guiding mechanism 3 and a pressing mechanism 6 are mounted on the support 1. An adjusting mechanism 4 is mounted on the guiding mechanism 3. The guiding mechanism 3 includes a side frame 301, which is mounted on the support 1. The adjusting mechanism 4 includes a movable opening 402. The movable opening 402 is obliquely opened at the top of the side frame 301. A rotating seat 403 located at the movable opening 402 is rotatably connected to the side frame 301. A labeling blade 401 is fixedly connected to the rotating seat 403. A mounting plate 404 located at the bottom of the movable opening 402 is mounted at the bottom of the side frame 301. The bottom of the mounting plate 404 is fixedly... A mounting bracket 405 is fixedly connected to the base plate 406, and two wedge blocks 408 are fixedly connected to the base plate 406. A trapezoidal block 409 is slidably connected to the base plate 406 between the two wedge blocks 408. A lead screw 411 is horizontally threaded onto one of the wedge blocks 408, and the lead screw 411 is rotatably connected to the trapezoidal block 409. Ball bearings 410 are placed on both sides of the trapezoidal block 409 between it and the two wedge blocks 408. Two push rods 407 are symmetrically rotatably connected to the mounting plate 404 about the rotating seat 403. The bottom of the push rods 407 is rotatably connected to the ball bearings 410, and the bottom of the push rods 407 abuts against the bottom of the marking tool 401. The height of the trapezoidal block 409 is equal to the height of the two wedge blocks 408, and the side of the trapezoidal block 409 forms an inverted V-shape with the two wedge blocks 408. One end of the marking blade 401 is inclined, and the other end of the marking blade 401 has a rectangular structure. The rotating seat 403 is located at the center of the rectangular bottom surface of the marking blade 401. The adjusting mechanism 4 also includes a baffle 412. Two sets of baffles 412 are symmetrically installed on the base plate 406 about the center of the two balls 410. The length of the baffle 412 is greater than the distance between the wedge block 408 and the trapezoidal block 409. The guiding mechanism 3 also includes a placement plate 302. The placement plate 302 is rotatably connected to the side frame 301, and a guide post 30 is rotatably connected to the side frame 301. 3 and guide post 304, the side frame 301 is equipped with a fixed frame 305 with an inverted L-shaped structure, the fixed frame 305 is equipped with a motor 307, the output end of the motor 307 is connected to a drive shaft 306 through a coupling; the conveying mechanism 2 includes a track 201, the support 1 is equipped with the track 201, the track 201 is rotatably connected to two rollers 204, the two rollers 204 are equipped with a conveyor belt 203, the track 201 is equipped with a motor 202, the output end of the motor 202 is fixedly connected to one of the rollers 204 through a coupling, the marking knife 401 and the drive shaft 306 are located inside the track 201, and the support 1 is equipped with a robot body 205;The pressing mechanism 6 includes a support frame 601, which is fixedly connected between the track 201 and the bracket 1. Two cylinders 602 opposite to the drive shaft 306 are mounted on the support frame 601. The extension and retraction ends of the two cylinders 602 are fixedly connected to a fixed frame 603 with a U-shaped structure. Pressure rollers 604 are vertically rotatably connected to the two fixed frames 603. The drive shaft 306 and the two pressure rollers 604 are arranged in a triangle. When labeling the outside of glass beverage bottles, the label backing paper is placed on the placement tray 302. Since the placement tray 302 is rotatably connected to the side frame 301, automatic feeding is achieved. The backing paper is pulled onto guide post 1 303 and guide post 2 304 and wound around them, further passing between the label cutter 401 and the drive shaft 306. Then, the backing paper passes over the other side of the label cutter 401 and rolls with guide post 3 502, finally fixing the end of the backing paper to the reel 504. The robot body 205 then loads the glass beverage bottle onto the conveyor belt 203. Motor 1 202 is started, causing the roller 204 to drive the conveyor belt 203 to rotate, completing the glass bottle transport. When the infrared sensor installed on the track 201 detects the arrival of the glass bottle, motor 2 307 is started, driving the drive shaft 306 to rotate. This, combined with the rotation of the reel 504, moves the backing paper. After a short distance, the labeling blade 401 peels off the label. When the glass bottle reaches the drive shaft 306, the control device extends the cylinder 602, and the two pressure rollers 604 clamp the glass bottle. The label is clamped between the glass bottle and the drive shaft 306. After the motor 307 rotates a certain number of times, it rotates the glass bottle itself, and the pressure rollers 604 rotate accordingly, completing the labeling. If the labeling blade 401 tilts due to uneven overall structure or vibration caused by the drive shaft 306 stopping and starting, resulting in the label being applied crookedly, the screw 411 connected to the horizontal thread on the wedge block 408 can be rotated. Since the screw 411 is rotatably connected to the trapezoidal block 409, rotating the screw 411 can drive the trapezoidal block 409 to slide between the two wedge blocks 408. The height of the trapezoidal block 409 is equal to the height of the two wedge blocks 408, and its side forms an inverted V with the two wedge blocks 408. In the trapezoidal block 409, during sliding, the balls 410 between the two sides of the trapezoidal block 409 and the two wedge blocks 408 roll accordingly, reducing friction and making the adjustment process smoother. Two push rods 407 are symmetrically rotatably connected to the mounting plate 404 about the rotating seat 403. The bottom of the push rods 407 rolls with the balls 410 and simultaneously abuts against the bottom of the blade 401. When the position of the trapezoidal block 409 changes, the position of the balls 410 changes accordingly, one rolling to the left and the other to the right, thus pushing one push rod 407 upwards and the other push rod 407 downwards. This causes one side of the trapezoidal block 409 to... The distance between the side of the trapezoidal block 409 and the wedge block 408 decreases, while the distance between the other side of the trapezoidal block 409 and another wedge block 408 increases. Since the bottom of the push rod 407 abuts against the bottom of the label knife 401, the rise and fall of the two push rods 407 adjusts the level of the label knife 401. One end of the label knife 401 is inclined, and the other end has a rectangular structure. The rotating seat 403 is located at the center of the rectangular surface at the bottom of the label knife 401. This structural design ensures the stability and accuracy of the level adjustment of the label knife 401, avoids slight deviations during the back paper feeding process that could cause the label to tilt, and is simple and quick to operate.

[0023] Specifically, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, an alarm mechanism 7 is installed on the sniper blade 401. The alarm mechanism 7 includes a controller 701 and an alarm 702. The controller 701 is installed on the mounting bracket 305, and the alarm 702 is electrically connected to the controller 701. A mounting base 703 is fixedly connected to the back side of the sniper blade 401. A stud 704 is slidably connected to the mounting base 703. A limit bracket 705 is fixedly connected to the bottom of the mounting base 703. A probe 706, which is fixed to the bottom of the stud 704, is slidably connected to the limit bracket 705. The probe 706 is hexagonal prism in shape. The structure includes a spring 708 on the outer side of the probe 706, one end of which is fixed to the side wall of the probe 706, and the other end of which is fixed to the bottom of the mounting base 703. A nut 709 is threaded onto the stud 704 and abuts against the mounting base 703. The probe 706 is electrically connected to the controller 701. The alarm mechanism 7 also includes a pressure plate 707, which is fixedly connected to the bottom of the probe 706 and fits against the side of the blade 401. The side of the blade 401 has a protrusion corresponding to the pressure plate 707. During normal operation of the device, the backing paper does not shift. The probe 706 maintains a relatively stable position under the constraint of the mounting base 703 and the limiting bracket 705. The probe 706 is fixed to the mounting base 703 by a stud 704 and a nut 709. The stud 704 can slide on the mounting base 703. By adjusting the position of the stud 704 and tightening the nut 709, the initial position of the probe 706 can be precisely set. A spring 708 is provided on the outside of the probe 706. One end of the spring 708 is fixed to the side wall of the probe 706, and the other end is fixed to the bottom of the mounting base 703. The function of the spring 708 is to allow the probe 706 to undergo elastic deformation when subjected to a certain external force and return to its original position after the external force disappears. When a label appears during the labeling process... If the label is misaligned, it will cause inaccurate labeling. This misalignment will cause the backing paper to push the pressure plate 707 at the bottom of the probe 706 upwards instead of downwards. Because the labeling knife 401 has a raised strip on its side, the spring 708 will retract at this time. The probe 706 is electrically connected to the controller 701. When the displacement of the probe 706 exceeds the preset value, the controller 701 will receive an abnormal signal and immediately trigger the alarm 702 to sound an alarm. The alarm 702 can emit sound or light signals to remind the operator to check the operating status of the device in time, troubleshoot the fault, avoid the backing paper from continuously shifting and causing inaccurate labeling, improve the labeling pass rate, detect problems in time, and avoid rework. Similarly, the level of the labeling knife 401 can be adjusted by rotating the lead screw 411.

[0024] Specifically, refer to Figure 1 , Figure 2 , Figure 8, Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, a winding mechanism 5 is mounted on the side frame 301. The winding mechanism 5 includes a drive disk 509, which is rotatably connected to the side frame 301. A motor 503 is mounted on the bottom of the side frame 301, and the output end of the motor 503 is keyed to the drive disk 509. The drive disk 509 has a cross-shaped groove, and a winding reel 501 is attached to the drive disk 509. A cross-shaped reinforcing frame 510 is welded to the bottom of the winding reel 501, and the reinforcing frame 510 engages with the groove on the drive disk 509. Two sliding rods 506 are slidably connected inside the drive disk 509, and springs 508 are clamped between the two sliding rods 506 and the drive disk 509. Inverted L-shaped grippers 507 are welded to the opposite ends of the two sliding rods 506, and the grippers 507 engage with the winding reel 501. A spool 504 is welded to the center of the surface of the take-up reel 501. A guide post 502 is rotatably connected to the side frame 301. The take-up mechanism 5 also includes a side groove 518. Two arc-shaped side grooves 518 are opened opposite each other on the spool 504. A middle plate 511 is welded to the center of the top of the spool 504. Outer sleeves 513 are welded opposite each other on both sides of the middle plate 511. Inner shafts 514 are slidably connected inside the two outer sleeves 513. Springs 517 are clamped between the two inner shafts 514 and the outer sleeves 513. Pressure shafts 512 that engage with the side grooves 518 are vertically fixedly connected to the opposite ends of the two inner shafts 514. Pressure rods 515 are slidably connected to the middle plate 511. A connecting rod 516 is rotatably connected between the pressure rod 515 and the two pressure shafts 512. Springs 505 are clamped between the pressure rod 515 and the middle plate 511. After the backing paper is separated from the label, it needs to be wound up. Therefore, a drive plate 509 is installed on the side frame 301. Pulling the two grippers 507 creates installation space, and the winding reel 501 is placed on the drive plate 509, so that the cross-shaped reinforcing bracket 510 at the bottom of the winding reel 501 engages with the cross-shaped groove on the drive plate 509, achieving initial positioning of the winding reel 501. Two sliding rods 506 are slidably connected inside the drive plate 509. Springs 508 are clamped between each sliding rod 506 and the drive plate 509. The opposite ends of the two sliding rods 506 are welded with inverted L-shaped... The gripper 507, with its triangular structure, retracts inward under the tension of spring 508, locking onto the take-up reel 501 to further secure it and prevent it from falling off during rotation. When the backing paper on the reel 504 needs to be replaced with the next backing paper, the pressure rod 515, which is slidably connected to the middle plate 511, is pressed down. The pressure rod 515 is rotatably connected to both pressure shafts 512 by connecting rods 516. Pressing down on the pressure rod 515 will drive the connecting rods 516 to move the backing paper. The two pressure shafts 512 expand outward, causing them to disengage from the side groove 518. At this point, the old backing paper can be removed, and the new backing paper can be placed inside the side groove 518. Then, the pressure rod 515 is released, the spring 517 returns to its original position, and the pressure shaft 512 will re-engage in the side groove 518. The replacement of the new backing paper is simple and labor-saving, without the need to move the existing elastic fixing clamp. When winding, the motor 503 is started to drive the drive disc 509 to rotate, so that the roll 504 can wind up the backing paper.

[0025] In use, the labeled backing paper is placed on the placement tray 302 for automatic feeding. The backing paper is then pulled onto guide posts 303 and 304 and wound around them, passing between the label cutter 401 and the drive shaft 306. Next, the backing paper passes over the other side of the label cutter 401 and rolls against guide post 502. Finally, the end of the backing paper is fixed to the roll 504. The robot body 205 then loads glass beverage bottles onto the conveyor belt 203. Starting motor 202 causes the roller 204 to drive the conveyor belt 203, completing the transport of the glass bottles. When the track 201 is... After the infrared sensor detects the arrival of the glass bottle, motor 2 (307) starts, driving drive shaft 306 to rotate. This, combined with the rotation of roller 504, moves the backing paper a short distance. Labeling knife 401 peels off the label. When the glass bottle reaches drive shaft 306, the control device extends cylinder 602, and two pressure rollers 604 clamp the glass bottle. The label is held between the glass bottle and drive shaft 306. After motor 2 (307) rotates a certain number of times, it rotates the glass bottle itself, causing the pressure rollers 604 to rotate accordingly, completing the labeling process. However, if the labeling knife 401 vibrates due to unevenness in its overall structure or vibration caused by intermittent rotation of drive shaft 306, the labeling process will be affected. When the label cutter 401 tilts, causing the label on the backing paper to be misaligned, the screw 411 connected to the horizontal thread on the wedge block 408 can be rotated. Rotating the screw 411 causes the trapezoidal block 409 to slide between the two wedge blocks 408. The balls 410 between the trapezoidal block 409 and the two wedge blocks 408 will roll accordingly, reducing friction and making the adjustment process smoother. When the position of the trapezoidal block 409 changes, the position of the balls 410 changes accordingly, one rolling to the left and the other rolling to the right, thereby pushing one of the push rods 407 to rise and the other push rod 407 to fall. The distance between one side of trapezoidal block 409 and wedge block 408 decreases, while the distance between the other side of trapezoidal block 409 and another wedge block 408 increases. Since the bottom of push rod 407 is in contact with the bottom of label knife 401, the rise and fall of the two push rods 407 adjusts the level of label knife 401. One end of label knife 401 is inclined, and the other end has a rectangular structure. Rotating seat 403 is located at the center of the rectangular surface at the bottom of label knife 401. This structural design ensures the stability and accuracy of the level adjustment of label knife 401, avoids small deviations during back paper feeding that cause labeling tilt, and is simple and quick to operate. Then, during normal operation of the device, the backing paper does not shift, and the probe 706 maintains a relatively stable position under the constraint of the mounting base 703 and the limiting bracket 705. The probe 706 is fixed to the mounting base 703 by the stud 704 and the nut 709. The stud 704 can slide on the mounting base 703. By adjusting the position of the stud 704 and tightening the nut 709, the initial position of the probe 706 can be accurately set. The function of the spring 708 is to enable the probe 706 to undergo elastic deformation when subjected to a certain external force and return to its original position after the external force disappears. When the label position shifts during the labeling process, resulting in inaccurate labeling, this shift will cause the backing paper to shift. Pushing the pressure plate 707 at the bottom of the probe 706 upwards will not cause it to move downwards because the side of the labeling knife 401 has a protrusion. At this time, the spring 708 retracts. The probe 706 is electrically connected to the controller 701. When the displacement of the probe 706 exceeds the preset value, the controller 701 will receive an abnormal signal and immediately trigger the alarm 702 to sound an alarm. The alarm 702 can emit sound or light signals to remind the operator to check the operating status of the device in time, troubleshoot the fault, avoid the back paper from continuously shifting and causing inaccurate labeling, improve the labeling qualification rate, detect problems in time, and avoid rework. Similarly, the level of the labeling knife 401 can be adjusted by rotating the screw 411. Finally, after the backing paper is separated from the label, it needs to be wound up. Therefore, a drive plate 509 is installed on the side frame 301. Pulling the two grippers 507 creates installation space, and the winding reel 501 is placed on the drive plate 509, so that the cross-shaped reinforcing bracket 510 at the bottom of the winding reel 501 engages with the cross-shaped groove on the drive plate 509, achieving initial positioning of the winding reel 501. Two sliding rods 506 are slidably connected inside the drive plate 509. Springs 508 are clamped between each sliding rod 506 and the drive plate 509. The opposite ends of the two sliding rods 506 are welded with inverted L-shaped... The gripper 507, with its triangular structure, retracts inward under the tension of spring 508, locking onto the take-up reel 501 to further secure it and prevent it from falling off during rotation. When the backing paper on the reel 504 needs to be replaced with the next backing paper, the pressure rod 515, which is slidably connected to the middle plate 511, is pressed down. The pressure rod 515 is rotatably connected to both pressure shafts 512 by connecting rods 516. Pressing down on the pressure rod 515 will drive the connecting rods 516 to move the backing paper. The two pressure shafts 512 expand outward, causing them to disengage from the side groove 518. At this point, the old backing paper can be removed, and the new backing paper can be placed inside the side groove 518. Then, the pressure rod 515 is released, the spring 517 returns to its original position, and the pressure shaft 512 will re-engage in the side groove 518. The replacement of the new backing paper is simple and labor-saving, without the need to move the existing elastic fixing clamp. When winding, the motor 503 is started to drive the drive disc 509 to rotate, so that the roll 504 can wind up the backing paper.
