Description

Technical Field

[0001] This utility model relates to the field of color printing and packaging technology, and in particular to a multi-sided labeling device for color printing and packaging. Background Technology

[0002] After the printing process is completed, color-printed packaging boxes typically require labels containing product information, anti-counterfeiting features, or promotional content to be affixed to multiple sides to meet the needs of commodity circulation and market management. With the improvement of automation levels, multi-sided labeling operations are generally completed using labeling equipment to improve production efficiency and labeling consistency. Existing color-printed packaging labeling devices mostly use a single-sided sequential labeling method, that is, labels are affixed to each side of the box in turn. This results in long operation cycles and slow production pace, making it difficult to meet the requirements of high-speed production lines. While some equipment has the function of simultaneous double-sided labeling, it usually uses two independent drive mechanisms to control the left and right labeling heads separately, leading to an increase in the number of motors, a complex control system, and a significant increase in equipment manufacturing and maintenance costs.

[0003] Furthermore, during the label supply process, the label tape is released by the unwinding mechanism, peeled off from the backing paper by the peeling plate, and then transferred by the labeling head. This process often results in label wrinkles, misalignment, or air bubbles due to sudden tension changes at the moment of peeling, affecting labeling quality. Simultaneously, the lack of an effective synchronous linkage mechanism between the unwinding and rewinding mechanisms makes the backing paper prone to loosening or breaking during high-speed operation, causing downtime for adjustments and affecting the continuous and stable operation of the equipment.

[0004] Therefore, it is necessary to design a multi-sided labeling device for color printing and packaging to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing color printing and packaging labeling devices, such as sudden tension changes during label peeling leading to label wrinkles or skewing, high equipment cost and complex control due to the use of independent drive structure for multi-sided labeling, and asynchronous unwinding and rewinding causing label tape slack or breakage affecting continuous operation, this utility model provides a color printing and packaging multi-sided labeling device.

[0006] The technical solution of this utility model is as follows: a multi-sided labeling device for color printing and packaging, including a frame, a control box, a first electric push rod, a connecting rod, a transition rod, a second electric push rod, a labeling head, a conveyor belt assembly, a connecting plate, a feeding cylinder, a dual-shaft motor, a rotating shaft, a fixed box, and a bevel gear. The control box is installed on the lower front side of the frame. A first electric push rod with its telescopic end facing left is installed on the right side of the frame. A connecting rod is fixed to the telescopic end of the first electric push rod. The connecting rod extends from the right side of the frame to the left and then branches into two branches, front and rear. The two branches extend horizontally along the front and rear sides of the frame to the upper part of their respective sides. A transition rod is vertically fixed to each extension end. A second electric push rod is fixed to the top of each of the two transition rods. The telescopic ends of the two second electric push rods face each other and are respectively fixed with labeling heads. The left side of the frame... A conveyor belt assembly is installed between the right two sides. A connecting plate is fixed on the top of the frame on both the front and rear sides of the conveyor belt assembly. The two connecting plates are parallel to each other and symmetrical with the longitudinal center line of the conveyor belt assembly. On the left side of the two connecting plates that are far apart from each other, a feeding cylinder is rotatably connected. The outer wall of the feeding cylinder is wound and fitted with the label tape. Fixed boxes are fixedly connected on the front and rear sides of the frame at the positions corresponding to the lower part of the feeding cylinder. A dual-shaft motor is installed on the lower left side of the frame. The front and rear output shafts of the dual-shaft motor are each connected to a rotating shaft through a coupling. The extended ends of the rotating shafts are fixed with bevel gears as driving components. A connecting cylinder is coaxially fixed at the bottom of the feeding cylinder. The connecting cylinder passes downward through the top wall of the fixed box and a bevel gear as a driven component is fixed inside the box. The driven bevel gear meshes with the driving bevel gear on the rotating shaft.

[0007] As a preferred technical solution of this utility model, it also includes a vertical plate and an anti-stick plate. The top of the frame is fixedly connected to the right end of the two connecting plates, and the vertical plate and the connecting plate are separated to form an opening. An anti-stick plate is fixed to each of the two vertical plates on their opposite sides. The anti-stick plate has a microporous vacuum chamber inside, and the vacuum chamber is connected to an external vacuum source through a solenoid valve. The surface of the anti-stick plate is treated with fluorocarbon to prevent label adhesive from adhering.

[0008] As a preferred technical solution of this utility model, it also includes limiting cylinders, with two limiting cylinders rotatably connected at intervals along the conveying direction on the outside of each connecting plate at the top of the frame.

[0009] As a preferred technical solution of this utility model, each of the two connecting plates has a discharge port on the inner side of its left end.

[0010] As a preferred technical solution of this utility model, it also includes a receiving cylinder and an adapter cylinder. The receiving cylinder is rotatably connected to the side of the two connecting plates that are far apart from each other, located on the left side of the feeding cylinder. The outer wall of the receiving cylinder is wound and fitted with the bottom paper. The receiving cylinder extends axially downward and is fixedly connected to the adapter cylinder.

[0011] As a preferred technical solution of this utility model, it also includes a transmission wheel and a belt. The shaft ends of the connecting cylinder and the adapter cylinder are both fixedly connected to a transmission wheel, and the two transmission wheels are connected by belt drive.

[0012] Beneficial effects: 1. This utility model sets up switchable vacuum anti-stick plates at the right ends of the two connecting plates. After the label is peeled off at the corner, it is temporarily adsorbed and positioned by the anti-stick plate, and then transferred by the labeling head. This achieves step-by-step peeling and precise transfer, effectively avoiding label wrinkles and improving the labeling qualification rate.

[0013] 2. This utility model uses a belt drive and drive wheel linkage structure between the feeding cylinder and the receiving cylinder to keep the label tape at a constant tension, prevent slack, and ensure continuous high-speed feeding and receiving.

[0014] 3. This utility model uses a first electric push rod to drive a forked connecting rod to move synchronously, which in turn drives the second electric push rods on the front and rear sides to move synchronously, so as to realize the simultaneous adsorption, transfer and pressing of the double-sided labeling head. It uses a single drive source to complete multi-sided labeling, which simplifies the structure and reduces the cost of equipment. Attached Figure Description

Detailed Implementation

[0021] Example: A multi-sided labeling device for color-printed packaging, such as... Figures 1-6As shown, the assembly includes a frame 1, a control box 2, a first electric push rod 3, a connecting rod 4, an adapter rod 5, a second electric push rod 6, a labeling head 7, a conveyor belt assembly 8, a connecting plate 11, a feeding cylinder 12, a dual-shaft motor 13, a rotating shaft 14, a fixed box 15, and a bevel gear 17. The control box 2 is installed on the lower front side of the frame 1. A first electric push rod 3 with its telescopic end facing left is installed on the right side of the frame 1. A connecting rod 4 is fixed to the telescopic end of the first electric push rod 3. The connecting rod 4 extends from the right side of the frame 1 to the left and then branches into two branches, one in front and one in back. These two branches extend horizontally along the front and rear sides of the frame 1 to the upper part of their respective sides. An adapter rod 5 is vertically fixed to each extension end. A second electric push rod 6 is fixed to the top of each of the two adapter rods 5. The telescopic ends of the two second electric push rods 6 face each other and are respectively fixed with a labeling head 7. A conveyor belt assembly 8 is installed between the left and right sides of the frame 1. The top of the frame 1 is above the conveyor belt. A connecting plate 11 is fixed on each of the front and rear sides of the conveyor belt group 8. The two connecting plates 11 are parallel to each other and symmetrical with the longitudinal center line of the conveyor belt group 8. The left side of the two connecting plates 11 that are far apart from each other is rotatably connected to the feeding cylinder 12. The outer wall of the feeding cylinder 12 is wound with the label tape for releasing the label tape. The front and rear sides of the frame 1 are respectively connected to the lower part of the feeding cylinder 12 by bolts to the fixing box 15. A dual-shaft motor 13 is installed on the lower left side of the frame 1. The front and rear output shafts of the dual-shaft motor 13 are each connected to a rotating shaft 14 through a coupling. The outer end of the rotating shaft 14 is fixed with a bevel gear 17 as the driving component. The bottom of the feeding cylinder 12 is coaxially fixed with a connecting cylinder 16. The connecting cylinder 16 passes downward through the top wall of the fixing box 15 and is fixed inside the box with a bevel gear 17 as the driven component. The driven bevel gear 17 meshes with the driving bevel gear 17 on the rotating shaft 14.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it also includes upright plates 9, anti-adhesion plates 10, and limiting cylinders 1201. Upright plates 9 are bolted to the right ends of two connecting plates 11 at the top of the frame 1. An opening is formed between the upright plates 9 and the connecting plates 11. Anti-adhesion plates 10 are fixed to the opposite sides of the two upright plates 9. Each anti-adhesion plate 10 has a microporous vacuum chamber inside, which is connected to an external vacuum source via a solenoid valve. The solenoid valve switches the on / off state to achieve label adsorption or release. The surface of the anti-adhesion plate 10 is fluorocarbon treated to prevent label adhesive from adhering. The top of the frame 1 has each connecting plate... Two limiting cylinders 1201 are rotatably connected to the outer side of the connecting plate 11 along the conveying direction. The limiting cylinders 1201 are used to guide and tighten the label tape. Each of the two connecting plates 11 has a discharge port 18 on the inner side of its left end. After the label tape is led out from the feeding cylinder 12, it passes around the two limiting cylinders 1201 in sequence along the outer side of the connecting plate 11 on the same side for guidance and tension. When it travels to the right corner of the connecting plate 11, the label is peeled off from the backing paper. The front end is adsorbed and fixed by the vacuum cavity of the anti-stick plate 10. The backing paper is folded back into the inner side of the connecting plate 11, discharged through the discharge port 18 and wound around the receiving cylinder 20.

[0023] like Figure 1 and Figure 6 As shown, it also includes a take-up cylinder 20, an adapter cylinder 19, a drive wheel 21, and a belt 22. The take-up cylinder 20 is rotatably connected to the side of the two connecting plates 11 that are far apart from each other, located on the left side of the feed cylinder 12. The outer wall of the take-up cylinder 20 is wound and fitted with the bottom paper to take up the peeled bottom paper. The axial direction of the take-up cylinder 20 extends downward and is connected to the adapter cylinder 19 by bolts. The shaft ends of the connecting cylinder 16 and the adapter cylinder 19 are both connected to a drive wheel 21 by bolts. The two drive wheels 21 are connected by a belt 22 to drive the feed cylinder 12 and the take-up cylinder 20 to rotate synchronously.

[0024] When this device is needed, first start the control box 2, the dual-axis motor 13 runs, and drives the feed cylinder 12 to rotate through the meshing transmission of the rotating shaft 14, the active bevel gear 17 and the driven bevel gear 17. The label tape is continuously released and driven by the belt 22. The take-up cylinder 20 and the feed cylinder 12 rotate synchronously to achieve constant linear speed recovery of the backing paper and ensure constant tape tension.

[0025] The label tape is led out from the feeding cylinder 12, passes around the outside of the two limiting cylinders 1201 in sequence to complete the guidance and tension, and then moves to the right along the outside of the connecting plate 11. At the right corner of the connecting plate 11, the front end of the label is lifted up and immediately attached to the microporous vacuum chamber of the anti-stick plate 10. The vacuum chamber is in an adsorption state, so that the label is temporarily laid flat on the surface of the anti-stick plate 10, waiting to be handed over.

[0026] When the box is fed between the two connecting plates 11 by the conveyor belt group 8, the first electric push rod 3 drives the connecting rod 4 to move laterally, so that the labeling head 7 is moved from the initial standby position to directly above the anti-stick plate 10; the anti-stick plate 10 is vacuum closed, the vacuum chamber of the labeling head 7 is opened, the second electric push rod 6 extends, and the label is adsorbed as a whole; then the first electric push rod 3 drives the labeling head 7 to move laterally to the labeling position on the corresponding side of the box, the telescopic end of the second electric push rod 6 drives the labeling head 7 to extend downward, pressing the label onto the surface of the box, the vacuum is closed after labeling is completed, and the second electric push rod 6 retracts to reset.

[0027] After the label is removed, the remaining backing paper enters the inner side of the connecting plate 11 from the folding point, passes to the left and is discharged from the inner discharge port 18 on the left end, and finally rolls around the outer wall of the receiving cylinder 20 to realize continuous recycling of waste. After completing one adsorption and release action, the anti-stick plate 10 returns to the standby state. Its fluorocarbon coating can prevent residual adhesive from adhering and ensure long-term reliable operation.

[0028] Throughout the process, the drive wheel 21 at the bottom of the connecting cylinder 16 drives the drive wheel 21 at the bottom of the adapter cylinder 19 via the belt 22, so that the receiving cylinder 20 and the feeding cylinder 12 rotate synchronously, ensuring that the label tape is always under constant tension. The box moves forward continuously on the conveyor belt group 8. The limiting cylinder 1201 protrudes from the inner edge of the connecting plate 11 to limit the box laterally, ensuring that the labeling position is consistent, thereby completing the multi-sided efficient labeling of color printing packaging.
