Description

Technical Field

[0001] This utility model relates to the field of label printing technology, and in particular to a label printing machine for packaging and decoration. Background Technology

[0002] A label printer is a device specifically designed for printing labels. It can customize labels according to user needs and print various types of labels, such as product labels, price tags, and address labels. This type of device typically uses thermal printing or thermal transfer technology. Label printers are used to affix labels to packaging during the decoration and printing process.

[0003] A label printing machine for packaging and decoration disclosed in Chinese patent CN221624228U includes a working plate: a rectangular hole is opened in the middle of the working plate, a support plate is fixedly connected to the lower side of the working plate, a collection box is provided on the outer side of the support plate, a placement unit is provided on the inner side of the rectangular hole, an electric push rod is fixedly connected to the upper side of the working plate, a top plate is fixedly connected to the upper end of the electric push rod, two top blocks are provided on the lower side of the top plate, two rotating shafts are rotatably connected to the outer side of the top blocks, a label roll is provided on the outer side of the rotating shaft, and the placement unit includes a rotating rod, which is rotatably connected to the inner side of the rectangular hole.

[0004] The existing device described above, when in use, is equipped with a working plate, rectangular holes, rotating rollers, fixing blocks, clamping plates, two electric push rods, and a label roll. This facilitates the control of the label roll to label the packaging, and the rotating rollers quickly discharge the labeled packaging. However, the clamping and releasing process of this device is still relatively cumbersome. It requires a motor to drive the placement plate on the rotating roller to rotate, causing the placement plate to rotate the labeled packaging downwards, and controlling the separation of the clamping plate from the packaging. This results in limitations of the existing structure, as the clamping / releasing process relies on the step-by-step actions of multiple components (rotating roller rotation and clamping plate opening and closing), leading to insufficient process integration efficiency.

[0005] To address the aforementioned problems, this utility model proposes a label printing machine for packaging and decoration. Utility Model Content

[0026] Please see Figure 1-5This utility model provides a technical solution: a label printing machine for packaging and decoration, including a collection box 1, a fixed bracket 2 fixedly mounted on the upper surface of the collection box 1, and a label roll 3 rotatably mounted on the fixed bracket 2; a vertical plate 4 is movably mounted on the upper surface of the collection box 1 corresponding to the label roll 3, and L-shaped movable plates 5 are slidably mounted on both sides of the vertical plate 4, with a clamping plate 6 fixedly connected to the side of the L-shaped movable plate 5 near the label roll 3; screws 7 are rotatably mounted on both sides of the vertical plate 4, and the screws 7 are threadedly connected to the corresponding L-shaped movable plates 5, with a linkage component between the vertical plate 4 and the screws 7. A collection port 13 is opened on the upper surface of the collection box 1, and the collection port 13 is located between the vertical plate 4 and the label roll 3.

[0027] The linkage assembly includes a connecting rod 8, a first bevel gear 9, a gear 10, a second bevel gear 11, and a toothed plate 12; a support plate 19 is fixedly installed on the side of the vertical plate 4 away from the label roll 3, and a connecting rod 8 is rotatably installed on both ends of the support plate 19. The first bevel gear 9 is fixedly installed on the top end of the connecting rod 8, and the gear 10 is fixedly installed on the bottom end of the connecting rod 8. The second bevel gear 11 is fixedly installed on the end of the screw 7 away from the vertical plate 4, and the second bevel gear 11 meshes with the first bevel gear 9. Toothed plates 12 are fixedly installed on both sides of the upper end face of the collection box 1, and the toothed plates 12 mesh with the corresponding gears 10.

[0028] A U-shaped plate 14 is fixedly installed on the upper surface of the collection box 1. The U-shaped plate 14 surrounds the outside of the vertical plate 4. An electric push rod 15 is fixedly installed on the U-shaped plate 14. The telescopic end of the electric push rod 15 is fixedly connected to the side of the vertical plate 4 away from the label roll 3.

[0029] In this embodiment of the utility model: a limiting groove 16 is provided on both sides of the U-shaped plate 14, and a slider 17 is slidably arranged inside the limiting groove 16. The two sides of the vertical plate 4 are respectively fixedly connected to the corresponding slider 17.

[0030] In this embodiment of the utility model: multiple springs 18 are fixedly connected to both sides of the vertical plate 4. The springs 18 on both sides are arranged longitudinally, and the other end of the spring 18 abuts against the corresponding L-shaped moving plate 5.

[0031] In this embodiment of the utility model: two rotating shafts are rotatably connected to the fixed bracket 2, and a label roll 3 is provided on the outside of the rotating shaft. A motor is fixedly installed on the outside of the fixed bracket 2. When in use, the motor is started, the motor drives the rotating shaft to rotate, and the rotating shaft drives the label roll 3 to rotate, so that the label on the label roll 3 can be easily affixed to the packaging.

[0032] Working principle:

[0033] During operation, the package to be labeled is placed in the gap between the vertical plate 4 and the clamping plate 6. After activating the electric push rod 15, its telescopic end pushes the vertical plate 4 smoothly along the limiting slide groove 16 of the U-shaped plate 14 towards the label roll 3. During this process, the connecting rods 8 fixed on both sides of the vertical plate 4 move accordingly, driving the bottom gear 10 to roll and mesh along the fixed tooth plate 12, forcing the gear 10 to rotate. This rotational motion is transmitted axially through the connecting rods 8, causing the first bevel gear 9 at the top to rotate synchronously, which in turn drives the second bevel gear 11 meshing with it to rotate. Since the second bevel gear 11 is coaxially fixed with the screw 7, the rotation of the screw 7 causes the threaded L-shaped moving plate 5 to slide along the limiting track of the vertical plate 4, driving the clamping plate 6 to press against the package laterally. The spring 18 is compressed at this stage, providing elastic preload to enhance clamping stability.

[0034] When the clamping plate 6 completes its clamping action, the gear 10 disengages from the meshing area of ​​the toothed plate 12, and the transmission chain self-locks to ensure that the clamping force continues to act. At this time, the packaging continues to move forward with the vertical plate 4, so that the label on the surface of the label roll 3 is pressed against the surface of the packaging to complete the labeling.

[0035] After labeling, the electric push rod 15 retracts in the reverse direction, and the vertical plate 4 retracts synchronously with the packaging. When the gear 10 re-engages with the toothed plate 12, the above transmission process is repeated in reverse: the gear 10 rolls in reverse, causing the first bevel gear 9 to reverse, which in turn causes the screw 7 to reverse through the second bevel gear 11, driving the L-shaped moving plate 5 to move outward and release the clamping plate 6. The spring 18 releases its stored energy to assist in resetting, and the unclamped packaging automatically falls into the collection box 1 through the collection port 13 under the action of gravity.

[0036] The entire process achieves sequential coordination of clamping, labeling, and release through mechanical linkage. The electric push rod 15, in conjunction with the reversing transmission of bevel gears 9 / 11 and gears 10 / tooth plate 12, ensures precise synchronization between clamping action and pushing stroke. It is suitable for continuous packaging production scenarios.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
