Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to an integrated labeling head. Background Technology

[0002] Labeling machines are used to affix labels to the surface of product packaging to indicate information such as the product manufacturer, storage method, and composition. For example, Chinese Patent 202221038816X discloses a high-speed labeling machine (by the same applicant), which includes a labeling machine body. The labeling machine body includes a labeling main body mechanism, a label peeling mechanism, a backing paper recycling mechanism, and a label placement mechanism. The label placement mechanism is located on one side of the labeling main body mechanism, the label peeling mechanism is located on the other side of the labeling main body mechanism, and the backing paper recycling mechanism is located on the upper side of the labeling main body mechanism. The label peeling mechanism can be located on the left or right side of the labeling main body mechanism, thereby realizing a left-out label mode and a right-out label mode.

[0003] However, the tension of the bottom paper recycling mechanism and label placement mechanism of the aforementioned high-speed labeling machine is difficult to control when unwinding the bottom paper and rewinding the labels, which can easily lead to loose winding and unwinding, resulting in slippage. In addition, the control unit needs to be additionally configured. Furthermore, the aforementioned high-speed labeling machine cannot detect when the bottom paper breaks or when a bundle of labels is finished being wound, requiring operators to observe frequently, which increases the labor intensity of the operators. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an integrated labeling head.

[0005] To achieve the above objectives, this utility model proposes an integrated labeling head, comprising: a control chassis, an unwinding shaft, a rewinding shaft, and a label peeling head disposed on the control chassis. The control chassis integrates an electronic control motherboard for controlling the operation of the equipment, an electronic control board for controlling the operation of the unwinding shaft, the rewinding shaft, and the label peeling head, and multiple connectors and data connectors connected to the electronic control motherboard are provided on the side of the control chassis, and a large-size touch screen is provided on the front of the control chassis.

[0006] The control box contains a gear set and a motor drive mechanism for driving the take-up shaft. The gear set of the gear set and the motor drive mechanism uses bevel teeth. The take-up shaft is equipped with a rocker arm, and the control box is equipped with a tension spring for pulling the rocker arm to rotate. The upper end of the rocker arm is equipped with multiple first guide rollers. A second guide roller is provided on the side of the control box of the take-up shaft. The free end of the bottom paper passes through the second guide roller, the first guide roller and the take-up shaft in sequence. The rocker arm is equipped with an arc-shaped sensing plate, and the side wall of the control box is inlaid with a bottom paper take-up detection system set on the front and rear sides along the swing trajectory of the rocker arm.

[0007] The control box contains a synchronous belt and motor drive mechanism that drives the label peeling head to pull the label roll and peel off the label; the label peeling head has a pressure plate for pressing the label paper, and a disassembly plate for connecting to the pressure plate is provided on the front side of the control box. The pressure plate is rotatably connected to the disassembly plate through a rotating shaft, and an adjusting screw for fixing the pressure plate is provided at the upper end of the pressure plate. The end of the adjusting screw is pressed against the end face of the disassembly plate.

[0008] The label peeling head is equipped with two aluminum blocks to press the label peeling plate firmly and prevent it from lifting. The aluminum blocks are symmetrically arranged on both sides of the label peeling plate.

[0009] Two fixing plates are provided on the control box on the upper and lower sides of the unwinding shaft. Both the upper and lower fixing plates are equipped with multiple third guide rollers to adjust the tension of the label paper.

[0010] Furthermore, the control cabinet side wall is provided with multiple mounting holes for installing external devices.

[0011] Furthermore, the control box has multiple through holes.

[0012] Furthermore, the bottom paper winding detection system includes two sensors located on the front and rear sides of the swing trajectory of the swing arm, and the sensors are electrically connected to the electronic control board.

[0013] Furthermore, elastic rollers that contact the swing arm are respectively provided on the control box on the sides of the two sensors.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By integrating the electronic control motherboard and electronic control board into the control box, the operation of the entire equipment and the independent control of the unwinding shaft, rewinding shaft, and label peeling head are realized, making the equipment integrated and usable when installed on corresponding production equipment without the need for additional control equipment, resulting in faster and more accurate labeling; the first guide roller, second guide roller, and third guide roller are set up so that the free end of the label passes through the first guide roller, second guide roller, and third guide roller, thereby increasing the tension and avoiding looseness during unwinding and rewinding, improving the balance of unwinding and rewinding; at the same time, a swing arm is set on the rewinding shaft, and... The first guide roller is mounted on the swing arm, and a bottom paper winding detection system is installed on the front and rear sides of the swing arm's swing trajectory on the control chassis. When the bottom paper passes over the first guide roller and connects to the winding shaft, it has a certain tension, causing the arc-shaped sensor on the swing arm to sense the corresponding sensor, thus detecting normal bottom paper feeding and winding. When the bottom paper breaks or is fully wound, since the first guide roller has no tension, the tension spring pulls the swing arm to rotate backward. When the arc-shaped sensor senses the corresponding sensor, the sensor sends a signal feedback to the electronic control board, which in turn sends a signal feedback to the main control board, causing the main control board to stop the equipment and issue an alarm to alert the operator. In addition, by setting a large-size touch screen, the operator can intuitively see the working status of the labeling head and various parameter settings, improving the convenience and intuitiveness of operation.

[0015] Furthermore, the bevel gear design not only improves transmission stability and precision but also effectively reduces noise and wear, extending the equipment's lifespan while minimizing space requirements. Notably, the disassembly plate and adjusting screw design in this invention simplify the installation and removal of the pressure plate, allowing for adjustment of the pressure force according to actual needs, further enhancing labeling effectiveness and equipment versatility. The aluminum block design effectively prevents the label-peeling plate from warping, ensuring stable and accurate label removal. Attached Figure Description

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides an integrated label applicator, which includes a control housing 10, an unwinding shaft 20, a rewinding shaft 30, and a label peeling head 40 mounted on the control housing 10. The rewinding shaft 30 is rotatably mounted on the control housing 10 via a bearing seat. The control housing 10 contains a gear set and a motor drive mechanism 301 for driving the rewinding shaft 30. The gear set of the gear set and the motor drive mechanism 301 uses bevel gears. This bevel gear design not only improves the stability and accuracy of the transmission but also effectively reduces noise and wear, extends the service life of the equipment, and reduces space occupation. The control housing 10 also contains a drive for the label peeling head 40 to pull the label. The control unit 10 includes a synchronous belt and motor drive mechanism 401 for peeling off labels; in addition, the control unit 10 integrates an electronic control motherboard 101 for controlling the operation of the equipment, an electronic control board 102 for controlling the operation of the unwinding shaft 20, the rewind shaft 30 and the label peeling head 40, a large 4.3-inch touch screen 50 with buttons on the front, and multiple connectors 103 and data connectors 104 connected to the electronic control motherboard 101 on the side of the control unit 10. Different external devices can be connected and data can be transmitted through the connectors 103 and data connectors 104, which improves the compatibility and expandability of the equipment and makes the operation and maintenance of the equipment more convenient.

[0022] To improve the tension of the label roll winding between the unwinding shaft 20, the take-up shaft 30, and the label peeling head 40 during the label paper conveying process, and to prevent loosening during winding and unwinding, the take-up shaft 30 is equipped with a rocker arm 302. Two first guide rollers 303 are located at the upper end of the rocker arm 302. A second guide roller 304 is located on the control housing 10 on the side of the take-up shaft 30. Simultaneously, two fixing plates 402 are located on the control housing 10 on both the upper and lower sides of the unwinding shaft 20. Both the upper and lower fixing plates 402... The system includes two third guide rollers 403 for adjusting the tension of the label paper. After the label roll is placed on the unwinding shaft 20, the free end of the label roll passes sequentially through the third guide roller 403, the label peeling head 40, the second guide roller 304, the first guide roller 303, and the take-up shaft 30. The take-up shaft 30 then winds up the label roll's bottom paper. By using multiple guide rollers, the label paper maintains appropriate tension during transport, effectively preventing loosening during winding and unwinding, and ensuring the stability and accuracy of the labeling process. Furthermore, the placement of the first guide roller 303, second guide roller 304, and third guide roller 403 makes the label paper transport path clearer and smoother, further improving labeling efficiency. Simultaneously, these guide rollers also have a guiding and limiting function, preventing the label paper from shifting or jamming during transport, thus ensuring labeling quality.

[0023] When the label roll is used up, it needs to be replaced, or the backing paper may break during the winding process. Operators need to constantly monitor whether the label roll is empty or the backing paper has broken. To reduce the operator's workload, please refer to [the relevant documentation / guideline]. Figure 4 A swing arm 302 is provided on the take-up shaft 30, and a tension spring 305 is provided on the control housing 10 to pull the swing arm 302 to rotate. An arc-shaped sensing plate 306 is provided on the swing arm 302, and a bottom paper winding detection system is embedded in the side wall of the control housing 10, which is arranged along the front and rear sides of the swing trajectory of the swing arm 302. The bottom paper winding detection system includes two sensors 307 that sense the arc-shaped sensing plate 306. The two sensors 307 are respectively arranged in front and rear sides of the swing trajectory of the swing arm 302, and the sensors 307 are electrically connected to the electronic control board 102. When the bottom paper passes through the first guide roller 303 and the take-up shaft 30, the system detects the bottom paper winding. When connected, a certain tension is applied, causing the arc-shaped sensing plate 306 on the swing arm 302 to sense the corresponding sensor 307, thereby detecting normal feeding and winding of the bottom paper. When the bottom paper is disconnected or winding is complete, since the first guide roller 303 has no tension, the tension spring 305 pulls the swing arm 302 to rotate backward. When the arc-shaped sensing plate 306 senses the corresponding sensor 307, the sensor 307 sends a signal feedback to the electronic control board 102. The electronic control board 102 sends the signal feedback to the electronic control main board 101, causing the electronic control main board 101 to control the equipment to stop operating and trigger an alarm to remind the operator.

[0024] In addition, on the control box 10 on the side of the two sensors 307, there are elastic rollers 308 that contact the swing arm 302. The elastic rollers 308 are mounted on the front of the control box 10 through a rotating shaft. The two elastic rollers 308 are set to prevent the swing arm 302 from rotating beyond the set range and play a limiting role.

[0025] In an optional embodiment, the label peeling head 40 is provided with a pressure plate 404 for pressing the label paper, and a disassembly plate 405 for connecting to the pressure plate 404 is provided on the front side of the control box 10. The disassembly plate 405 is fixed to the front side of the control box 10 by screws. The pressure plate 404 is rotatably connected to the disassembly plate 405 through a rotating shaft. The upper end of the pressure plate 404 is provided with an adjusting screw for fixing the pressure plate 404. The end of the adjusting screw is pressed against the end face of the disassembly plate 405. By rotating the adjusting screw, the end of the adjusting screw is disengaged from the disassembly plate 405 so as to adjust the pressure plate 404. By adjusting the pressure plate 404, the label is pressed against the power roller on the label peeling head 40, and the label is tightened. When the synchronous belt and the motor drive mechanism 401 drive the power roller to rotate, the label is pulled. The disassembly plate 405 is provided to remove and replace the pressure plate 404.

[0026] In an optional embodiment, the label peeling head 40 is provided with aluminum blocks 406 for pressing the label peeling plate 407 to prevent it from warping. Two aluminum blocks 406 are provided and symmetrically arranged on both sides of the label peeling plate 407. This arrangement ensures that the label peeling plate 407 remains stable during operation, preventing poor label peeling due to warping. The aluminum blocks 406 are fixed to corresponding positions on the label peeling head 40 by screws or other fasteners, maintaining close contact with the label peeling plate 407 for a good pressing effect.

[0027] In an optional embodiment, the control chassis 10 is provided with multiple through holes 105, and multiple mounting holes 106 for installing external devices are provided on the side wall of the control chassis 10. The multiple through holes 105 facilitate the installation of the integrated labeling head on the corresponding device. The design of the mounting holes 106 allows users to flexibly add or remove external devices according to actual needs, improving the versatility and scalability of the device. Simultaneously, connecting the corresponding connector 103 via a connector ensures accurate information transmission and guarantees the stability and precision of the labeling process.

[0028] In summary, this integrated labeling head incorporates the control unit within the labeling head, effectively simplifying the equipment's structure and operation, making the entire labeling process more efficient and convenient. Furthermore, by optimizing the design and layout of internal components, the equipment's reliability and durability are improved, reducing maintenance and replacement costs. This integrated design not only enhances labeling efficiency but also strengthens the equipment's flexibility and adaptability, enabling it to meet the needs of various industries and fields.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
