Description

Technical Field

[0001] This utility model belongs to the field of marking equipment technology, specifically relating to a laser marking label machine. Background Technology

[0002] In the field of label marking, traditional label identification codes are usually achieved through spraying or mechanical coding machines; however, these traditional methods have many shortcomings. First, labels formed by spraying or mechanical coding are easily tampered with, lacking anti-counterfeiting and reliability. Second, in harsh environments, traditional label identification codes are easily damaged, thus affecting product identification and authentication. In addition, traditional label marking technology is cumbersome, inefficient, time-consuming, and labor-intensive when meeting various types of identification style conversions.

[0003] Therefore, in view of the above-mentioned technical defects such as insufficient anti-counterfeiting, poor environmental adaptability and low operating efficiency, there is an urgent need for a new label paper marking device to solve the above problems and improve the efficiency, reliability and anti-counterfeiting of label marking. Utility Model Content

[0007] The label paper tray is used to store label paper and rotate to output label paper; the label paper conveying mechanism drives the label paper to move towards the marking station through rolling friction; the paper pressing device includes a quadrilateral frame and is used to press the label paper tightly so that the label paper is flat and the laser marking machine completes the marking operation.

[0008] The laser marking machine is mounted on a height-adjustable frame, and its working area is located in the middle of the paper pressing device. The height-adjustable frame is used to adjust the working height of the laser marking machine.

[0009] The paper pressing device is equipped with a paper cutting mechanism on the outlet side. The paper cutting mechanism is used to cut the label paper and is connected to a paper outlet hopper.

[0010] This application has the following technical features and combined technical effects:

[0011] Integrated design: The label marking unit integrates label paper tray, height-adjustable frame, laser marking machine, paper cutting mechanism, label paper conveying mechanism and paper pressing device. All functional modules are compactly arranged in the same unit. The integrated design reduces the equipment's footprint, simplifies the production process, avoids the complex material transfer and coordination problems between multiple independent modules in traditional equipment, and significantly improves production efficiency.

[0012] The laser marking machine is mounted on a height-adjustable frame and moves up and down through mechanical structures such as lead screws, guide rails, and drive motors to accommodate label paper of different thicknesses. The height adjustment function ensures that the laser marking machine can work at the optimal focal length, guaranteeing the stability and consistency of marking quality regardless of the thickness of the label paper, thus improving the versatility and adaptability of the equipment.

[0013] The label paper conveying mechanism achieves smooth label paper transmission through a drive motor and upper and lower rollers, while a reset spring ensures tight contact between the upper and lower rollers. The paper pressing device adopts a quadrilateral frame structure with an internal pressing mechanism to ensure that the label paper is flat and wrinkle-free during the marking process. It effectively solves the problems of wrinkles and offset that are prone to occur during label paper transmission in traditional equipment, ensuring the accuracy and consistency of the marking content, while improving the operational stability and reliability of the equipment.

[0014] The paper cutting mechanism uses a pneumatic or electric driven cutter. The up and down movement of the cutter is controlled by a cylinder or motor to achieve automatic cutting of the label paper.

[0075] like Figure 1-17 A laser marking label machine, including a label marking integrated host 100;

[0076] The label marking integrated host 100 is set in the upper compartment of the main electrical cabinet 200. The main electrical cabinet 200 is equipped with a secondary electrical cabinet 300. The main electrical cabinet 200 and the secondary electrical cabinet 300 are used to control the label marking integrated host 100 in a linkage manner to realize the marking operation.

[0077] The label marking integrated host 100 includes a label paper tray 101, a height adjustment frame 102, a laser marking machine 103, a paper cutting mechanism 106, a label paper conveying mechanism 108, and a paper pressing device 110;

[0078] The label paper tray 101 is used to store label paper and rotate to output label paper; the label paper conveying mechanism 108 drives the label paper to move towards the marking station through rolling friction; the paper pressing device 110 includes a quadrilateral frame and is used to press the label paper tightly so that the label paper is flat and the laser marking machine 103 completes the marking operation.

[0079] The laser marking machine 103 is mounted on the height adjustment frame 102, and the working area of ​​the laser marking machine 103 is located in the middle of the paper pressing device 110. The height adjustment frame 102 is used to adjust the working height of the laser marking machine 103.

[0080] The paper pressing device 110 is provided with a paper cutting mechanism 106 on the outlet side. The paper cutting mechanism 106 is used to cut label paper. The paper cutting mechanism 106 is connected to a paper outlet hopper 107.

[0081] When implementing this application, the key points are as follows:

[0082] Compared to existing technologies, which suffer from multiple, dispersed processes, low efficiency, susceptibility to wrinkles and misalignment, unstable quality, frequent adjustments required for different thicknesses, poor versatility, manual feeding and cutting, high labor intensity, complex structure, and large footprint, these technologies have the following drawbacks:

[0083] This application features an integrated design with a high degree of automation and significantly improved efficiency; the height adjustment and clamping device ensures high marking quality; the height adjustment function offers strong adaptability; and the automated paper cutting and output require minimal manual intervention. The integrated design results in a compact structure and small footprint.

[0084] The working principle and process of this application are as follows:

[0085] I. Working Principle

[0086] The laser marking label machine of this application integrates the processes of label paper feeding, conveying, pressing, marking, cutting, and unloading into a single main unit through an integrated design, and achieves automated operation by combining it with an electrical control system; its core working principle is as follows:

[0087] 1. Label feeding and conveying:

[0088] The label roll is installed on the label reel 101 and rotated by a motor to continuously output the label roll;

[0089] The output label paper is limited by the label paper guide post 1011 and enters the label paper conveying mechanism 108; the conveying mechanism drives the lower roller 1082 to rotate through the drive motor 1081, and uses the friction between the upper and lower rollers to drive the label paper to move towards the marking station.

[0090] 2. Label paper pressing and flattening treatment:

[0091] After the label paper enters the paper pressing device 110, it is pressed onto the work platform by a pressing mechanism (such as a spring or cylinder, or the weight of the parts) to ensure that the label paper is flat and wrinkle-free during the marking process. The quadrilateral frame structure of the paper pressing device 110 provides stable support, and the internal pressing components can adjust the pressure according to the thickness and material of the label paper.

[0092] 3. Laser marking:

[0093] The laser marking machine 103 is mounted on the height adjustment frame 102, and the marking height can be adjusted according to the thickness of the label paper to ensure that the working area of ​​the laser marking machine 103 accurately covers the middle of the paper pressing device 110;

[0094] The laser marking machine 103 controls the movement and energy output of the laser beam to perform high-precision etching and marking on the compressed label paper, ensuring the clarity and anti-counterfeiting of the marked content;

[0095] 4. Label cutting and output:

[0096] After the label paper is marked, it enters the paper cutting mechanism 106, and the cutter is driven up and down by a cylinder or motor to realize the automatic cutting of the label paper.

[0097] The cut label paper is output through the paper output hopper 107, and the paper output detection device 1071 monitors the paper output status in real time to ensure that the cut label paper is output smoothly.

[0098] 5. Electrical control and linkage:

[0099] The main electrical cabinet 200 and the auxiliary electrical cabinet 300 are linked and controlled through a communication module. The main electrical cabinet 200 is equipped with a display device 203 and operation buttons 202 for human-machine interaction and equipment monitoring.

[0100] The tri-color warning light 201 is used to display the equipment's operating status in real time, ensuring that operators can understand the equipment's operating status and perform corresponding operations in a timely manner.

[0101] II. Work Process

[0102] 1. Device startup and initialization:

[0103] The operator starts the equipment via the operation button 202 on the main electrical cabinet 200. The equipment performs a self-test and initializes each functional module.

[0104] Display device 203 displays the equipment status, and the three-color warning light 201 lights up green, indicating that the equipment is ready;

[0105] 2. Label feeding:

[0106] Install the roll of label paper on the label paper tray 101, manually pass one end of the label paper through the label paper guide post 1011, and introduce it between the upper and lower rollers of the label paper conveying mechanism 108;

[0107] 3. Label paper feeding and clamping:

[0108] The label paper conveying mechanism 108 is started, and the drive motor 1081 drives the lower roller 1082 to rotate, and the label paper is conveyed forward by the friction between the upper and lower rollers.

[0109] After the label paper enters the paper pressing device 110, the pressing mechanism presses the label paper firmly onto the working platform to ensure that the label paper is flat and wrinkle-free;

[0110] 4. Laser marking:

[0111] The laser marking machine 103 adjusts to the optimal marking height according to the preset marking content and parameters through the height adjustment frame 102;

[0112] Laser marking machine 103 starts up and performs high-precision laser etching and marking on the compressed label paper to complete the printing of the label content;

[0113] 5. Label cutting and output:

[0114] After the label paper is marked, it enters the paper cutting mechanism 106. The paper cutting mechanism 106 starts according to the preset cutting length. The cylinder or motor drives the cutter to move up and down to complete the cutting of the label paper.

[0115] The cut label paper is output through the paper output hopper 107, and the paper output detection device 1071 monitors the paper output status in real time to ensure that the label paper is output smoothly.

[0116] 6. Equipment monitoring and shutdown:

[0117] Throughout the entire operation, the main electrical cabinet 200 monitors the equipment's operating status in real time and provides feedback on the equipment information through the display device 203;

[0118] If any abnormal situation occurs (such as paper jam, marking error, etc.), the three-color warning light 201 will light up red, the equipment will automatically stop, and the operator can troubleshoot and restart the equipment through the operation button 202;

[0119] The laser marking label machine of this application realizes fully automated operation from label paper feeding to marking, cutting and unloading, which significantly improves production efficiency and marking quality, while reducing manual intervention and equipment costs, and has high practicality and innovation.

[0120] Specifically, in one embodiment of this application, a label paper guide post 1011 is provided between the label paper tray 101 and the label paper conveying mechanism 108. A pressing mechanism support post I 111 and a pressing mechanism support post II 112 are provided on both sides of the label paper conveying mechanism 108 and above it. The label paper conveying mechanism 108 includes a drive motor 1081, a lower roller 1082, and an upper roller 1083. The drive motor 1081 drives the lower roller 1082. Both ends of the upper roller 1083 are equipped with reset springs 1088 for driving the upper roller 1083 and the lower roller 1082 to abut and press against each other. One end of the reset spring 1088 abuts against the frame, and the other end abuts against the end of the upper roller 1083.

[0121] The label paper in the label paper tray 101 is limited by the label paper guide post 1011 and enters the rolling drive of the label paper conveying mechanism 108. The label paper conveying mechanism 108 drives the label paper into the paper pressing device 110.

[0122] To ensure stable label paper delivery and accurate labeling, a label paper guide column 1011 is installed between the label paper tray 101 and the label paper delivery mechanism 108 to guide the direction of the label paper and ensure that it remains flat and does not deviate during delivery. At the same time, the pressing mechanism support column I 111 and the pressing mechanism support column II 112 are respectively installed on both sides of the label paper delivery mechanism 108 and above it to support the paper pressing device 110, ensuring that the label paper can be accurately pressed before entering the marking area and avoiding wrinkles or deviations during the marking process.

[0123] The elastic force of the spring makes the upper roller 1083 and the lower roller 1082 in close contact, thereby providing a stable friction force when the label paper passes through, ensuring that the label paper can be smoothly and evenly conveyed to the paper pressing device 110. After the label paper is output from the label paper tray 101, it is first limited by the label paper guide post 1011, and then enters the rolling drive of the label paper conveying mechanism 108. Driven by the cooperation of the upper roller 1083 and the lower roller 1082, it is finally conveyed to the paper pressing device 110, preparing for subsequent labeling operations.

[0124] This embodiment can effectively solve the problems of wrinkles and misalignment that easily occur in the label paper during the transmission process in traditional label marking equipment, while ensuring that the label paper is accurately pressed before marking, thereby improving the marking quality and production efficiency.

[0125] Specifically, in one embodiment of this application, the label paper conveying mechanism 108 is equipped with a roller lifting mechanism, which drives the upper roller 1083 to overcome the elastic force of the reset spring 1088 and disengage from the lower roller 1082.

[0126] The roller lifting mechanism includes a cylinder 1084, a sliding block 1085, a pressure roller plate 1086, a chute block 1087, a pressing mechanism support column I 111, and a pressing mechanism support column II 112. The cylinder 1084, the pressing mechanism support column I 111, and the pressing mechanism support column II 112 are mounted on the machine frame.

[0127] A sliding block 1085 is provided at the telescopic end of the cylinder 1084; sliding groove blocks 1087 are provided at both ends of the sliding block 1085, and a sliding pair is formed between the two ends of the sliding block 1085 and the sliding groove blocks 1087; the sliding groove blocks 1087 are provided on the support column I 111 and the support column II 112 of the pressing mechanism; the lower end of the sliding block 1085 is fixedly connected to the pressure roller plate 1086, and the lower end of the pressure roller plate 1086 is connected to both ends of the upper roller 1083;

[0128] The cylinder 1084 drives the upper roller 1083 away from the lower roller 1082 by means of the sliding block 1085 and the pressure roller plate 1086.

[0129] The roller lifting mechanism can drive the upper roller 1083 to overcome the elastic force of the reset spring 1088 and disengage from the lower roller 1082, thereby facilitating the replacement, adjustment or cleaning of the label paper, while avoiding roller surface wear caused by prolonged contact.

[0130] The lifting roller mechanism drives the upper roller 1083 through the cylinder 1084 to overcome the elastic force of the reset spring 1088, realizing the rapid separation and contact between the upper roller 1083 and the lower roller 1082. The operation is simple and the response is rapid. The cylinder is used as the power source. Through the sliding pair formed by the sliding block 1085 and the sliding groove block 1087, it is ensured that the upper roller 1083 moves smoothly along the predetermined trajectory during the lifting process and avoids deviation. At the same time, the pressure roller plate 1086 reliably transmits the power of the cylinder to the upper roller 1083, while the pressure mechanism support column I 111 and the pressure mechanism support column II 112 provide stable support and limit the movement of the sliding block 1085, ensuring the stability of the entire mechanism.

[0131] On the one hand, it facilitates the replacement, adjustment, and cleaning of label paper, reducing maintenance and downtime. On the other hand, it reduces wear caused by prolonged contact between the upper roller 1083 and the lower roller 1082, extending the service life of the rollers. The cylinder-driven automated roller lifting function simplifies manual operation, improves the automation level and ease of operation of the equipment, and ensures the stability of label paper conveying, avoiding instability caused by upper roller wobbling, thereby ensuring labeling quality and production efficiency.

[0132] Specifically, in one embodiment of this application, a buffer spring is provided between the pressing mechanism support column I 111, the pressing mechanism support column II 112 and the frame; a sliding pair is formed between the upper roller 1083 and the frame; a paper output detection device 1071 is provided on the paper output hopper 107, which is used to determine the paper output after cutting; paper arching detection devices 109 are provided before the inlet and after the outlet of the label paper conveying mechanism 108, which are used to determine the working condition of the label paper material; a smoke processor interface 104 and a smoke hood 105 are respectively provided on both sides of the marking operation area of ​​the laser marking machine 103, and the smoke processor interface 104 and the smoke hood 105 are used to treat the smoke in the marking operation space of the laser marking machine 103 surrounding the paper pressing device 110;

[0133] A buffer spring is installed between the clamping mechanism support column I111 and the clamping mechanism support column II112 and the frame. The buffer spring can effectively absorb the impact force generated during the label paper conveying and clamping process, reduce the impact of mechanical vibration on the equipment accuracy, protect the clamping mechanism from damage by excessive stress, and extend the service life of the equipment.

[0134] The upper roller 1083 is connected to the frame via a precision-machined sliding pair. This sliding pair design ensures that the upper roller 1083 can move smoothly and steadily during operation, reducing frictional resistance and improving the stability and accuracy of label paper delivery. At the same time, the structural design of the sliding pair also facilitates maintenance and adjustment, ensuring long-term stable operation of the equipment.

[0135] A paper output detection device 1071 is installed on the paper output hopper 107 to monitor in real time whether the cut label paper is output normally. The device detects the paper output status of the label paper through photoelectric sensors or proximity switches and feeds the signal back to the control system. Once an abnormal paper output is detected (such as paper jam or missing cut), the system will automatically alarm and stop the machine to avoid production interruption or defective products caused by paper output problems.

[0136] Arching detection devices 109 are installed before the inlet and after the outlet of the label paper conveying mechanism 108. These devices can monitor the arching or wrinkling of the label paper in real time during the conveying process to ensure that the label paper remains flat before entering the marking area. Once an abnormality is detected in the label paper, the system will adjust the tension of the conveying mechanism or stop the machine in time to ensure the stability and consistency of the marking quality.

[0137] A smoke processor interface 104 and a fume hood 105 are respectively installed on both sides of the marking operation area of ​​the laser marking machine 103. The smoke and odor generated during the laser marking process are effectively collected by the fume hood 105 and transmitted to the external smoke purification equipment for treatment via the smoke processor interface 104. This system not only optimizes the environment of the marking operation space, but also meets environmental protection requirements and protects the health of the operators.

[0138] Specifically, in one embodiment of this application, the main electrical cabinet 200 includes an upper compartment and a lower compartment, both of which are equipped with cabinet doors; the layered design separates the control and display functions from the core control host, facilitating maintenance and operation; the cabinet doors are made of high-strength metal material and the surface is treated with anti-corrosion to ensure the durability and protective performance of the electrical cabinet; a transparent observation window is provided on the cabinet door, allowing operators to observe the status of the internal equipment without opening the cabinet door;

[0139] The lower compartment is equipped with a control host; the control host, as the core control unit of the entire equipment, adopts a high-performance industrial-grade computer or PLC (programmable logic controller); the control host realizes the automated control of the equipment through internal circuit boards, processors and memory, including the coordinated operation of components such as drive motors, laser marking machines, and sensors;

[0140] The control host is connected to each actuator and sensor via cables to ensure the stability and reliability of signal transmission; the lower compartment is also equipped with a cooling fan and filter to keep the operating temperature of the control host within a safe range and to prevent dust from entering.

[0141] The upper compartment is equipped with a display device 203 and an operation button 202 on its side wall. The display device 203 uses a high-resolution touch screen or LCD screen to display the equipment's operating status, parameter settings, alarm information, etc. in real time. The operation button 202 is used to manually control the equipment's start, stop, emergency stop and other basic operations, ensuring that the operator can still intervene in the equipment's operation at any time during the automated operation process.

[0142] The upper surface of the upper compartment is equipped with a three-color warning light 201 to intuitively display the operating status of the equipment. The three-color warning light provides immediate feedback to the operator through different colors (such as green for normal operation, yellow for warning, and red for malfunction), which facilitates quick identification of the equipment status and the taking of corresponding measures.

[0143] In summary, this utility model aims to solve many problems existing in traditional label marking equipment, such as low production efficiency, unstable marking quality, complex equipment structure, excessive manual intervention, and lack of automation and intelligent control. Through integrated design, the processes of label paper feeding, conveying, pressing, marking, cutting, and unloading are integrated into the same host machine. Combined with height adjustment, pressing device, automated paper cutting, paper output detection, and linkage electrical control system, fully automated label marking operation is achieved. This technical solution not only significantly improves production efficiency and marking quality, but also enhances the adaptability and reliability of the equipment, reduces manual intervention and equipment costs, and improves the overall level of intelligence, providing an efficient, stable, and economical solution for the label marking field.

[0144] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0145] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
