Abstract
Description
Technical Field
[0001] This utility model relates to the field of label paper traction technology, specifically to a traction mechanism for cutting label paper. Background Technology
[0002] In the label paper slitting process, the traction mechanism is a key component to ensure slitting quality, efficiency and equipment stability. Its core function is to solve problems such as tension fluctuation, deviation and inaccurate cutting that may occur during the slitting process by precisely controlling the movement of the material.
[0003] For example, the label paper auxiliary traction mechanism for adhesive tape disclosed in patent CN222410388U includes a machine base, a base on one side of the top of the machine base, a control panel mounted on one side of the top of the base via a bracket, a first motor mounted on the top of the base on one side of the control panel via a bracket, a belt drive mechanism on the upper surface of the base at one end of the first motor, a traction roller mounted on the inner wall of the belt drive mechanism on one side of the first motor via a rotating shaft, a transmission frame on the top of the machine base on one side of the base, a bearing plate above the transmission frame, a piece holder on the top of the bearing plate, an unwinding roller rotatably connected to the inner wall of the piece holder, and a lead screw rotatably connected at the center position inside the transmission frame. However, this patent relies solely on mechanical structures (such as traction rollers and lead screws) for position and tension control. Mechanical contact measurement is prone to measurement errors due to material surface characteristics (such as transparency, reflectivity, uneven roughness), affecting the accuracy of traction and slitting. Furthermore, it relies solely on manual observation and adjustment, requiring manual intervention when the material deviates, leading to reduced production efficiency and unstable slitting quality.
[0004] Therefore, it is necessary to invent a traction mechanism for cutting label paper to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a traction mechanism for cutting label paper, which solves the problem that relying solely on mechanical structures for position and tension control, and relying solely on manual observation and adjustment, requires manual intervention when the material deviates from its intended path.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a traction mechanism for label paper cutting, comprising a frame, an operation panel on the front side of the frame, a detection mechanism arranged inside the frame along the label paper conveying direction, the detection mechanism including a connecting rod, the connecting rod being installed on the inner wall of the frame, a connecting sleeve sleeved on one side of the connecting rod, an ultrasonic sensor disposed below the connecting sleeve, a correction execution mechanism disposed on one side of the detection mechanism, the correction execution mechanism including a servo motor, the servo motor being located on the front wall of the frame, the output end of the servo motor being connected to a ball screw and rotatably mounted on the frame, a ball nut being threaded onto the ball screw, a correction sleeve disposed on the outer side of the ball nut, a controller disposed below the servo motor and located on the side wall of the operation panel, for receiving the detection signal from the ultrasonic sensor and controlling the correction action of the servo motor, a drive roller disposed on one side of the correction execution mechanism, and a driven roller disposed directly above the drive roller.
[0007] Preferably, a support plate is provided on one side wall of the frame, a conveying roller is provided on one side above the support plate, and two guide rollers are rotatably installed on the other side above the support plate.
[0008] Preferably, a lead screw is arranged parallel to the ball screw directly below it, and a sliding sleeve is slidably sleeved on the lead screw. The sliding sleeve is located directly below the correction sleeve, and the sliding sleeve and the correction sleeve are fixedly connected.
[0009] Preferably, the outer surface of the correction sleeve is provided with anti-slip protrusions made of silicone material.
[0010] Preferably, a drive motor is disposed below the drive roller and located on the inner wall of the frame. The output end of the drive motor is connected to one shaft end of the drive roller through a transmission mechanism. The transmission mechanism consists of two transmission gears and a tensioned toothed belt. One transmission gear is installed at the output end of the drive motor, and the other transmission gear is installed at one shaft end of the drive roller.
[0011] Preferably, the drive roller has a drive wheel at its shaft end, and a driven wheel is meshed and connected directly above the drive wheel and installed at the shaft end of the driven roller.
[0012] Preferably, a traction roller is provided on one side of the drive roller, and a pressure roller is provided directly above the traction roller. A second transmission mechanism is provided on one shaft end of the traction roller and one shaft end of the pressure roller. The second transmission mechanism consists of two transmission gears and a tensioned toothed belt. One transmission gear is installed on one shaft end of the driven roller, and the other transmission gear is installed on one shaft end of the traction roller.
[0013] Preferably, the two ends of the pressure roller are slidably mounted in through slots opened on both sides of the frame via bearings, and a cylinder is fixedly mounted on the top of the frame, with the cylinder output end connected to the top surface of the bearing.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. This utility model solves the problem of relying solely on mechanical structures for position control by setting up a detection mechanism and a correction execution mechanism in conjunction. In the detection mechanism, the ultrasonic sensor can detect the position information of the label paper in real time. Once the label paper is detected to be off-center, the controller will quickly receive the detection signal and control the servo motor to drive the ball screw to rotate, thereby moving the correction sleeve to perform the correction operation on the label paper. This realizes automated position control and improves the accuracy and stability of label paper delivery.
[0016] 2. This utility model solves the problem of manual intervention required when materials deviate due to reliance on manual observation and adjustment through an automated detection and correction system. In the past, operators needed to constantly observe the label paper's delivery and manually adjust it as soon as deviation was detected. This not only increased the intensity of manual labor but also made it difficult to guarantee the timeliness and accuracy of manual adjustments. The automated detection and correction system of this utility model can react instantly when the label paper deviates, without the need for manual intervention, greatly improving production efficiency. It also avoids label paper cutting quality problems caused by untimely or inaccurate manual adjustments, ensuring product consistency and quality stability. Attached Figure Description

Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] This utility model provides, for example Figure 1-5 The illustrated label paper cutting traction mechanism includes a frame 1. An operation panel 2 is located on the front side of the frame 1. A detection mechanism 6 is arranged inside the frame 1 along the label paper conveying direction. The detection mechanism 6 includes a connecting rod 601, which is mounted on the inner wall of the frame 1. A connecting sleeve 602 is fitted onto one side of the connecting rod 601. An ultrasonic sensor 603 is located below the connecting sleeve 602. A correction actuator 7 is located on one side of the detection mechanism 6. The correction actuator 7 includes a servo motor 701, which is located on the front wall of the frame 1. The output end of the servo motor 701 is connected to a ball screw 702 and rotatably mounted on the frame 1. A ball nut 703 is threaded onto the upper part of the ball nut 703. A correction sleeve 704 is provided on the outer side of the ball nut 703. A lead screw 707 is arranged parallel to the ball screw 702 directly below it. A sliding sleeve 708 is slidably sleeved on the lead screw 707. The sliding sleeve 708 is located directly below the correction sleeve 704 and is fixedly connected to the correction sleeve 704. The outer surface of the correction sleeve 704 is provided with anti-slip protrusions 705 made of silicone. A controller 706 is provided below the servo motor 701 and located on the side wall of the operation panel 2. It is used to receive the detection signal of the ultrasonic sensor 603 and control the correction action of the servo motor 701. A drive roller 8 is provided on one side of the correction actuator 7. A driven roller 9 is provided directly above the drive roller 8.
[0026] In this embodiment, the ultrasonic sensor 603 has an adjustable angle of 45°±15° with the label paper plane. When the ultrasonic sensor 603 detects that the label paper is off-center, it transmits a signal to the controller 706. The controller 706 has a built-in adaptive PID algorithm. Therefore, the controller 706 controls the servo motor 701 to rotate according to the detection signal. The servo motor 701 drives the ball screw 702 to rotate, and the ball nut 703 moves along the ball screw 702, which in turn drives the correction sleeve 704 to move, correcting the off-center label paper. The screw 707 and the sliding sleeve 708 play an auxiliary support and guiding role to ensure the stability of the movement of the correction sleeve 704. The silicone anti-slip protrusions 705 can increase the friction between the correction sleeve 704 and the label paper, prevent the label paper from slipping during the correction process, and improve the correction effect.
[0027] A support plate 3 is provided on one side wall of the frame 1, a conveying roller 4 is provided on one side above the support plate 3, and two guide rollers 5 are rotatably installed on the other side above the support plate 3.
[0028] In this embodiment, the conveying roller 4 is used to introduce the label paper into the slitting and traction mechanism, and the two guide rollers 5 can guide the label paper to ensure that the label paper is on the correct conveying path before entering the detection mechanism 6 and the correction execution mechanism 7, so as to avoid the label paper from deviating in the initial stage and lay the foundation for subsequent accurate detection and correction.
[0029] A drive motor 10 is located below the drive roller 8 and on the inner wall of the frame 1. The output end of the drive motor 10 is connected to one shaft end of the drive roller 8 through a transmission mechanism 11. The transmission mechanism 11 consists of two transmission gears and a tensioned toothed belt. One transmission gear is installed at the output end of the drive motor 10, and the other transmission gear is installed at one shaft end of the drive roller 8.
[0030] In this embodiment, the drive motor 10 drives the drive roller 8 to rotate through the transmission mechanism 11, providing power for the conveying of the label paper. The transmission mechanism 11 adopts a combination of transmission gears and toothed belts, which can ensure stable power transmission. At the same time, the tensioned toothed belt can prevent slippage during transmission, ensuring that the drive roller 8 rotates at a stable speed, thereby achieving precise control of the label paper conveying speed.
[0031] A drive roller 8 has a drive wheel 12 at its shaft end. A driven roller 13 is meshed and connected above the drive roller 12 and installed on the shaft end of the driven roller 9. A traction roller 14 is provided on one side of the drive roller 8. A pressure roller 15 is provided directly above the traction roller 14. A transmission mechanism 2 16 is provided on one shaft end of the traction roller 14 and one shaft end of the pressure roller 15. The transmission mechanism 2 16 consists of two transmission gears and a tensioned toothed belt. One transmission gear is installed on one shaft end of the driven roller 9, and the other transmission gear is installed on one shaft end of the traction roller 14. The two ends of the pressure roller 15 are slidably installed in the through slots opened on both sides of the frame 1 through bearings. A cylinder 17 is fixedly installed at the top of the frame 1, and the output end of the cylinder 17 is connected to the top surface of the bearing.
[0032] In this embodiment, the meshing connection between the driving wheel 12 and the driven wheel 13 enables the driving roller 8 and the driven roller 9 to rotate synchronously, and there is a certain pressure between them, which can reliably clamp the label paper and ensure that the label paper will not slip during the conveying process, thus ensuring the stability and accuracy of the label paper conveying. Furthermore, the driven roller 9 drives the traction roller 14 to rotate through the transmission mechanism 16. The cooperation between the traction roller 14 and the pressure roller 15 further pulls and conveys the label paper, ensuring that the label paper can smoothly pass through the entire slitting and traction mechanism. The transmission mechanism 16 also employs... The combination of transmission gears and toothed belts ensures stable power transmission, enabling the traction roller 14 and driven roller 9 to rotate synchronously, improving the continuity and stability of label paper conveying. Furthermore, cylinder 17 can control the up-and-down movement of pressure roller 15, thereby adjusting the pressure between pressure roller 15 and traction roller 14. When it is necessary to adapt to label paper of different thicknesses or materials, the position of pressure roller 15 can be adjusted by cylinder 17 to ensure that pressure roller 15 and traction roller 14 can provide appropriate clamping force, which can ensure the normal conveying of label paper and avoid damage to the label paper due to excessive pressure.
[0033] Working principle of this utility model:
[0034] Refer to the instruction manual appendix Figure 1-5When using this invention, firstly, one end of the label roll to be cut is passed around the conveyor roller 4 on the support plate 3, allowing the label to enter the traction mechanism. After passing the conveyor roller 4, the label passes around the two guide rollers 5 rotatably mounted above the support plate 3, ensuring the label is on the correct conveying path. The label continues to be conveyed into the detection mechanism 6 area. The ultrasonic sensor 603 detects the label's position information in real time. If the ultrasonic sensor 603 detects that the label is not deviating, the label passes normally through the detection mechanism 6 and enters the subsequent conveying and cutting process. If the ultrasonic sensor 603 detects that the label... When the paper deviates from its designated path, the detection signal is transmitted to the controller 706. Based on the received detection signal, the controller 706 controls the servo motor 701 to rotate. The servo motor 701 drives the ball screw 702 to rotate, and the ball nut 703 moves along the ball screw 702, which in turn drives the correction sleeve 704 to move. At the same time, the screw 707 and the sliding sleeve 708 provide auxiliary support and guidance to ensure the stable movement of the correction sleeve 704. The outer surface of the correction sleeve 704 is provided with anti-slip protrusions 705 made of silicone material to increase the friction between the correction sleeve and the label paper and prevent the label paper from slipping during the correction process, thereby correcting the deviated label paper.
[0035] After correction, the label paper enters between the drive roller 8 and the driven roller 9. The drive motor 10 starts and drives the drive roller 8 to rotate through the transmission mechanism 11. The drive roller 8 rotates simultaneously with the driven roller 9, which in turn drives the label paper forward. After the label paper passes between the drive roller 8 and the driven roller 9, it enters between the traction roller 14 and the pressure roller 15. The driven roller 9 drives the traction roller 14 to rotate through the transmission mechanism 2 16. The transmission mechanism 2 16 makes the traction roller 14 and the driven roller 9 rotate synchronously. According to the thickness and material of the label paper, the cylinder 17 is controlled by the operation panel 2. The output end of the cylinder 17 pushes or pulls the bearings at both ends of the pressure roller 15, so that the pressure roller 15 moves up and down in the through slots opened on both sides of the frame 1, thereby adjusting the pressure between the pressure roller 15 and the traction roller 14 to ensure that the two can provide a suitable clamping force. The traction roller 14 and the pressure roller 15 cooperate to further pull and transport the label paper, ensuring that the label paper can pass smoothly through the entire traction mechanism.
