Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a labeling machine for a special-shaped packaging box. Background Art

[0002] A labeling machine is a device that uses adhesive to stick paper or metal foil labels on specified packaging containers. The existing labeling machine uses a label pulling mechanism to pull the label belt to move. The label passes through a vertical plate and is partially separated from the label belt. The packaging box sticks to the packaging box when passing the label, and then a round roller or a flat plate is used to smooth the label and press it onto the packaging box. However, when the existing labeling machine labels the special-shaped surface of a special-shaped packaging box, the round roller or the flat plate cannot be pressed onto the special-shaped surface of the packaging box as a whole, and the label is often not completely attached to the packaging box, resulting in the label easily falling off during the subsequent transportation of the packaging box.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 As shown, the utility model provides a special-shaped packaging box labeling machine, including a fuselage 1, a conveyor belt 2 is installed on the fuselage 1, a label holding structure 3 and a vertical plate 5 are installed on the left side plate of the conveyor belt 2, a baffle structure 4 is installed on the right side plate of the conveyor belt 2, a label pulling mechanism 6 and a main control screen 7 are installed on the fuselage 1, the label pulling mechanism 6 is located on the left side of the conveyor belt 2, and guide plates 8 are installed on the left and right side plates of the conveyor belt 2 through brackets. When the labeling machine is used, the label tape needs to bypass the vertical plate 5 and be installed on the label pulling mechanism 6. The label will be separated from the label tape when passing the vertical plate 5, and the adhesive side of the label tape will stick to the packaging box when the packaging box passes the vertical plate 5, thereby tearing the label off the label tape.

[0025] like Figure 2 and Figure 3 As shown, the label structure 3 includes a first base 31, which is installed on the left side plate of the conveyor belt 2. A rotating shaft 32 is installed on the first base 31, and a plurality of L-shaped plates 33 are arranged on the rotating shaft 32. One end of the L-shaped plate 33 is rotatably installed on the rotating shaft 32, and a pressure wheel 34 is horizontally rotatably installed on the other end of the L-shaped plate 33. A second stopper 37 is installed on the L-shaped plate 33, and a torsion spring 36 is arranged on the L-shaped plate 33. The torsion spring 36 is sleeved on the rotating shaft 32 and one end is fixed to the rotating shaft 32, and the other end of the torsion spring 36 is against the second stopper 37. The rotating shaft 32 corresponds to the position of the L-shaped plate 33 A first stopper 35 is provided, and under normal conditions, the L-shaped plate 33 is pressed against the first stopper 35 by a torsion spring 36. During the process of labeling the irregular surface of the packaging box, the packaging box will push the pressure wheel 34 outward when passing through the label-stroking structure 3, causing the L-shaped plate 33 to rotate slightly. Each L-shaped plate 33 on the rotating shaft 32 can rotate independently, so that the pressure wheel 34 on each L-shaped plate 33 can be pressed on the irregular surface of the packaging box. Multiple pressure wheels 34 cooperate to press the label as a whole onto the irregular surface of the packaging box. At the same time, the outer ring of the pressure wheel 34 is covered with a thick silicone pad 38 to prevent the pressure wheel 34 from scratching the packaging box.

[0026] like Figure 4As shown, the baffle structure 4 includes a second base 41, which is installed on the right side plate of the conveyor belt 2. Two vertical first guide rods 42 are slidably installed on the second base 41. The third base 44 and the first bottom plate 43 are installed at the upper and lower ends of the first guide rod 42 respectively. A first screw 45 is rotatably installed between the first bottom plate 43 and the third base 44. A screw hole is provided on the second base 41, and the first screw 45 cooperates with the screw hole. The bottom end of the shaft of the first screw 45 passes through the first bottom plate 43 and is installed with a first knob 46. Two horizontal second guide rods 47 are slidably installed on the third base 44. A baffle 49 and a second bottom plate 48 are installed at the left and right ends of the second guide rod 47 respectively. A second screw 410 is rotatably installed between the second bottom plate 48 and the baffle 49. The third base 44 is provided with a screw hole, and the second screw 410 cooperates with the screw hole. The right end of the shaft of the second screw 410 passes through the second bottom plate 48 and is installed with a second knob 411. Rotating the first knob 46 can control the rotation of the first screw 45, and then the height of the baffle 49 can be adjusted by cooperating the first screw 45 with the screw hole on the second base 41. Rotating the second knob 411 can control the rotation of the second screw 410, and then the horizontal position of the baffle 49 can be adjusted by cooperating the second screw 410 with the screw hole on the third base 44. The front and rear edges of the left side of the baffle 49 are provided with slopes. When the packaging box passes through the baffle 49, it will be displaced a short distance toward the label structure 3 and the vertical plate 5 through the slope, so that the packaging box is closer to the label, making it easier for the label to stick to the packaging box.

[0027] The working principle and use process of this utility model:

[0028] Before using the special-shaped packaging box labeling machine, the label tape is passed around the vertical plate 5 and installed on the label pulling mechanism 6. After the labeling machine is started, the special-shaped packaging box is placed on the conveyor belt 2. The conveyor belt 2 moves forward with the packaging box and first reaches the baffle structure 4. The packaging box is displaced a short distance toward the label pulling structure 3 and the vertical plate 5 through the slope of the baffle 49. Then the packaging box passes through the vertical plate 5, and the label is adhered to the packaging box. The packaging box then passes through the label pulling structure 3. During this process, the packaging box pushes the pressure wheel 34 outward, causing the L-shaped plate 33 to rotate slightly. Under the tension of the torsion spring 36, the L-shaped plate 33 causes the pressure wheel 34 to squeeze the special-shaped surface of the packaging box for labeling. After passing through the pressure wheel 34, the label is tightly attached to the packaging box. Each L-shaped plate 33 on the rotating shaft 32 can rotate independently, so that the pressure wheel 34 on each L-shaped plate 33 can be pressed on the special-shaped surface of the packaging box. Multiple pressure wheels 34 cooperate to press the label as a whole on the special-shaped surface of the packaging box, so that the label is more firmly attached.

[0029] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
