Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, specifically to an engine cache printing labeling machine. Background Technology

[0002] In modern industrial production, engine buffer printing and labeling machines are widely used in many industries due to their integration and automation advantages. They can efficiently complete the unwinding, printing and labeling of label films, reduce costs and are easy to maintain. However, the buffer components of existing equipment still have some defects. For example, the buffer components of existing engine buffer printing and labeling machines mostly rely on a single mechanical elastic structure, and their buffering force adjustment range is limited, making it difficult to adapt to label films of different materials, thicknesses and unwinding speeds, thus making it difficult to ensure the stability of the buffering effect. In addition, existing engine buffer printing and labeling machines have limited means to precisely control the label film transmission speed and tension, making it difficult to meet the high-precision labeling requirements of modern production. Utility Model Content

[0003] The purpose of this application is to provide an engine buffer printing labeling machine to solve the problem that traditional buffer components in the prior art cannot guarantee the stability of the buffering effect, as well as the problem that there are limited means to accurately control the label film transmission speed and tension.

[0004] One embodiment of this utility model provides an engine buffer printing labeling machine, including a labeling machine body and an unwinding component, a film guiding component, a printing engine, a buffer component, and a film taking component mounted on the mounting surface of the labeling machine body. The labeling machine body is provided with a discharge port, and a label dispensing component is provided at the discharge port. The buffer component is located above the label dispensing component, and the unwinding component is located away from the label dispensing component. The film guiding component and the printing engine are installed between the unwinding component and the label dispensing component. The buffer component is used to counteract the impact force on the label film during its movement after being released from the unwinding component and passing through the printing engine and the film guiding component. It also works with the film guiding component to adjust the buffering force and the label film tension, so that the label film can reach the label dispensing component smoothly.

[0005] In one embodiment, the buffer component includes a reset shaft, a swing arm, and a buffer shaft. The reset shaft is movably connected to the mounting surface, the swing arm is mounted on the reset shaft, and the buffer shaft is mounted on the swing arm.

[0006] In one embodiment, a reset bearing block is provided on the side of the mounting surface opposite to the reset shaft, and the reset shaft is rotatably connected in the reset bearing block.

[0007] In one embodiment, a limiting member is provided on the mounting surface, and the limiting member is located on the swing rod.

[0008] In one embodiment, the film guiding component includes an unwinding guide shaft, a dispensing guide shaft, and a take-up guide shaft. The unwinding guide shaft is located on one side of the unwinding component, the dispensing guide shaft is located on one side of the dispensing component, and the take-up guide shaft is located on one side of the take-up component.

[0009] In one embodiment, the labeling machine body is equipped with multiple motors, and the unwinding guide shaft, the label dispensing guide shaft, and the take-up guide shaft are respectively connected to different motors.

[0010] In one embodiment, the dispensing component includes a dispensing shaft and a dispensing support plate, with the dispensing guide shaft located above the dispensing support plate.

[0011] In one embodiment, the unwinding component includes an unwinding shaft, a first unwinding tray, a clamping block, a second unwinding tray, and a mounting block. A gasket and the clamping block are respectively installed on both sides of the first unwinding tray, and a label top block and the mounting block are respectively installed on both sides of the second unwinding tray. Both the first unwinding tray and the second unwinding tray are mounted on the unwinding shaft.

[0012] In one embodiment, the mounting block is provided with a disassembly wrench, which is used to disassemble or install the mounting block.

[0013] In one embodiment, the film collection component includes a film collection shaft for collecting the printed label film.

[0014] It should be noted that during actual processing, when the label film is transferred from the unwinding component to the buffer component via the printing engine, if speed fluctuations or impacts occur, the swing arm will rotate around the reset shaft. Since the reset shaft is connected in the reset bearing block, the rotation of the swing arm will drive the reset shaft to rotate accordingly. At this time, a pre-set elastic connection method can be used, taking the elastic connection method in which one end of the rotating tension spring is fixed to the mounting surface and the other end is indirectly in contact with the swing arm or the reset shaft as an example. This allows the rotation of the reset shaft to drive the swing arm to squeeze or stretch the rotating tension spring. During this process, the tension spring undergoes elastic deformation under force, and the resulting elastic reaction force is transmitted to the swing arm through the reset shaft, forming a damping force opposite to the direction of the impact force, thereby dynamically offsetting the impact force and ensuring smooth transmission of the label film. In actual processing, the motors controlling the speeds of the unwinding guide shaft, the label feeding guide shaft, and the take-up guide shaft can all be connected to the same host computer. The host computer can then independently control the operating status of each motor, thereby adjusting the speed difference between the shafts to achieve tension regulation. Specifically, when insufficient label film tension is detected, the unwinding guide shaft motor decelerates to reduce the unwinding speed, while the take-up guide shaft motor accelerates to increase the take-up tension, thus improving the tension. When the tension is too high, the unwinding guide shaft accelerates while the take-up guide shaft decelerates to reduce the tension. When the tension of the guide film assembly is adjusted as described above, the buffer shaft will automatically adapt to the changes in the tightness of the label film as the swing rod rotates. Specifically, when the tension increases, the label film pulls the buffer shaft upward, the swing rod rotates and compresses the rotary spring, and the elastic force of the spring is fed back to the label film to form flexible tension adjustment. When the tension decreases, the rotary spring rebounds and pushes the swing rod downward, so that the buffer shaft applies appropriate pressure to the label film to prevent it from loosening.

[0015] In this solution, the buffer component dynamically offsets the impact force during the movement of the label film, and works in conjunction with the film guide component to adjust the buffering force and label film tension. This effectively overcomes the limitation of the existing equipment's limited buffering force adjustment range. Specifically, when dealing with label films of different materials and thicknesses, and under different unwinding speeds, the buffer component and film guide component can adjust the buffering force in real time to ensure stable buffering effect. At the same time, the buffer component and film guide component can precisely control the label film tension, avoiding the shaking and offset problems caused by uneven tension. Compared with existing engine buffer printers, this significantly improves the tension control accuracy of the label film, thereby reducing the label scrap rate and improving overall production efficiency and product quality.

[0022] Please refer to Figures 1-4One embodiment of this utility model provides an engine buffer printing labeling machine, including a labeling machine body 1 and an unwinding component 2, a film guiding component 3, a printing engine 4, a buffer component 5, and a film taking component 6 mounted on the mounting surface 11 of the labeling machine body 1. The labeling machine body 1 is provided with a discharge port 7, and a label dispensing component 8 is provided at the discharge port 7. The buffer component 5 is located above the label dispensing component 8. The unwinding component 2 is disposed away from the label dispensing component 8. The film guiding component 3 and the printing engine 4 are installed between the unwinding component 2 and the label dispensing component 8. The buffer component 5 is used to counteract the impact force on the label film during its movement after being released from the unwinding component 2 and passing through the printing engine 4 and the film guiding component 3. It also works with the film guiding component 3 to adjust the buffering force and the label film tension so that the label film can reach the label dispensing component 8 smoothly.

[0023] In one embodiment, the buffer component 5 includes a reset shaft 51, a swing rod 52, and a buffer shaft 53. The reset shaft 51 is movably connected to the mounting surface 11, the swing rod 52 is mounted on the reset shaft 51, and the buffer shaft 53 is mounted on the swing rod 52.

[0024] In one embodiment, a reset shaft 51 support block (not shown) is provided on the side of the mounting surface 11 opposite to the reset shaft 51, and the reset shaft 51 is rotatably connected in the reset shaft 51 support block (not shown).

[0025] In one embodiment, a limiting member 12 is provided on the mounting surface 11, and the limiting member 12 is located on the swing rod 52.

[0026] In one embodiment, the film guiding component 3 includes an unwinding guide shaft 31, a bid dispensing guide shaft 32, and a take-up guide shaft 33. The unwinding guide shaft 31 is located on one side of the unwinding component 2, the bid dispensing guide shaft 32 is located on one side of the bid dispensing component 8, and the take-up guide shaft 33 is located on one side of the take-up component 6.

[0027] In one embodiment, the labeling machine body 1 is provided with multiple motors (not shown), and the unwinding guide shaft 31, the label dispensing guide shaft 32 and the take-up guide shaft 33 are respectively connected to different motors (not shown).

[0028] In one embodiment, the dispensing component 8 includes a dispensing shaft 81 and a dispensing support plate 82, with the dispensing guide shaft 32 located above the dispensing support plate.

[0029] In one embodiment, the unwinding component 2 includes an unwinding shaft 21, a first unwinding tray 22, a clamping block 23, a second unwinding tray 24, and a mounting block 25. A gasket 26 and the clamping block 23 are respectively installed on both sides of the first unwinding tray 22, and a label top block 27 and the mounting block 25 are respectively installed on both sides of the second unwinding tray 24. Both the first unwinding tray 22 and the second unwinding tray 24 are mounted on the unwinding shaft 21.

[0030] In one embodiment, the mounting block 25 is provided with a disassembly wrench 9, which is used to disassemble or install the mounting block 25.

[0031] In one embodiment, the film collection component 6 includes a film collection shaft 61 for collecting the printed label film.

[0032] It should be noted that during actual processing, when the label film is transferred from the unwinding component 2 to the buffer component 5 via the printing engine 4, if speed fluctuations or impacts occur, the swing arm 52 will rotate around the reset shaft 51. Since the reset shaft 51 is rotatably connected in the reset shaft 51 support block (not shown), the rotation of the swing arm 52 will drive the reset shaft 51 to generate a corresponding rotational action. At this time, a pre-set elastic connection method can be used, taking the elastic connection method in which one end of the rotating tension spring is fixed on the mounting surface 11 and the other end is indirectly in contact with the swing arm 52 or the reset shaft 51 as an example, so that the rotation of the reset shaft 51 drives the swing arm 52 to squeeze or stretch the rotating tension spring. During this process, the tension spring is subjected to force and undergoes elastic deformation. The elastic reaction force generated is transmitted to the swing arm 52 through the reset shaft 51, forming a damping force opposite to the direction of the impact force, thereby dynamically offsetting the impact force and ensuring the smooth transmission of the label film. In actual processing, the motors (not shown) that control the rotation speed of the unwinding guide shaft 31, the label dispensing guide shaft 32, and the take-up guide shaft 33 can be connected to the same host computer. The host computer can independently control the working status of each motor (not shown), thereby adjusting the tension by adjusting the speed difference between the shafts. Specifically, when insufficient label film tension is detected, the unwinding guide shaft 31 motor decelerates to reduce the unwinding speed, while the take-up guide shaft 33 motor accelerates to increase the take-up tension, thereby increasing the tension. When the tension is too high, the unwinding guide shaft 31 accelerates and the take-up guide shaft 33 decelerates to reduce the tension. When the tension of the guide film assembly is adjusted as described above, the buffer shaft 53 will also automatically adapt to the changes in the tightness of the label film as the swing rod 52 rotates. Specifically, when the tension increases, the label film pulls the buffer shaft 53 upward, the swing rod 52 rotates and compresses the rotary spring, and the elastic force of the spring is fed back to the label film to form flexible tension adjustment. When the tension decreases, the rotary spring rebounds and pushes the swing rod 52 downward, so that the buffer shaft 53 applies appropriate pressure to the label film to prevent it from loosening.

[0033] It should be noted that when dealing with label films of different materials and thicknesses, the guide film component 3 and the buffer component 5 can also be adaptively adjusted by the host computer to make them adaptable. For example, for thinner thermal paper labels, the guide film component 3 can reduce the speed difference between the axes to reduce the initial tension, while the buffer component 5 provides gentle cushioning through the small deformation of the rotating tension spring to prevent the label from tearing. For thicker PET labels, the guide film component 3 can increase the speed difference to increase the tension, while the buffer component 5 provides stronger damping through the large deformation of the rotating tension spring to ensure smooth label transmission.

[0034] It should be further explained that, at different unwinding speeds, the guide film component 3 and the buffer component 5 can also be adaptively adjusted by the host computer to make them adaptable. For example, at high-speed unwinding (such as above 200 mm / s), the guide film component 3 accelerates the rotation of each axis, and the buffer component 5 absorbs high-frequency impact force through rapid swinging and the elastic force of the tension spring, reducing vibration. At low-speed unwinding (such as below 50 mm / s), the buffer component 5 maintains constant tension through slow swinging and the preload of the tension spring, preventing the label from loosening.

[0035] In this embodiment, the buffer component 5 can dynamically offset the impact force during the movement of the label film, and works in conjunction with the film guide component 3 to adjust the buffering force and label film tension. This effectively overcomes the limitation of the buffering force adjustment range in existing equipment. Specifically, when dealing with label films of different materials and thicknesses, and under different unwinding speeds, the buffer component 5 and the film guide component 3 can adjust the buffering force in real time to ensure a stable buffering effect. At the same time, the buffer component 5 and the film guide component 3 can precisely control the label film tension, avoiding the shaking and offset problems caused by uneven tension of the label film. Compared with existing engine buffer printers, this significantly improves the tension control accuracy of the label film, thereby reducing the label scrap rate and improving overall production efficiency and product quality.
