Description

Technical Field

[0001] The utility model relates to the technical field of printing and labeling machines, in particular to a label arc pressing device for printing and labeling machines. Background Art

[0002] The printer labeler is an automated device that integrates printing and labeling functions. When labels need to be pasted on curved objects (such as some curved cans, bottles, etc.), the label pressing device of the printer labeler is required.

[0003] A Chinese patent with publication number CN221114748U discloses a printing and labeling machine for curved surface printing and labeling. The labeling work on the curved surface can is realized by using a cylinder, a compacting block, an arc-shaped mouth, a movable plate, a limiting groove and a label separation plate. A conveyor belt is usually provided at the bottom of the movable plate to drive the movement of the movable plate. The curved surface can is placed in the limiting groove of the movable plate. When the label on the label paper moves to the label separation plate, it will be peeled off from the label paper. The peeled label will fall onto the curved surface can. The cylinder pushes the compacting block downward, and the arc-shaped mouth just fits and compacts the label and the curved surface can, thereby completing the curved surface labeling work. This solves the problem that the traditional printing and labeling printing and labeling machine is not suitable for curved surface labeling, and greatly improves the practicality of the device.

[0004] However, the material and shape of the compacting block of the printing and labeling machine in the above scheme are fixed and cannot be changed according to the material of the can body, which may damage the can body, and the can body itself cannot roll, so that it cannot fully contact with the label paper and achieve stable adhesion.

[0005] Therefore, it is necessary to invent a label camber pressing device for a label printing and labeling machine. Utility Model Content

[0034] Working principle: When using this solution, firstly, the cans can be labeled by using a printing and labeling machine (it should be noted that the printing and labeling machine is an existing mature technology in this field, and its specific working principle, general structure and conventional functions are not described here, and the innovation and protection focus of this patent are not on this), and the cans with labels can be placed on the U-shaped groove base 18, (wherein a gripper can be used to assist in completing the placement of the can into the U-shaped groove base 18, and the use of a gripper to grip tightly is also a mature existing technology in the current technical field. This type of gripper device and its corresponding operation method have been widely used in industrial production, and its basic working principle, structural composition and operation process are all well known to technicians in this field. Therefore, in this patent application document, this part of the existing technical content will no longer be explained and described in detail), and then the electric telescopic rods 15 on both sides are started, so that the clamps 16 on both sides move towards each other to clamp the cans;

[0035] Then, the cylinder 192 can be started, which will drive the top plate 193 to move downward, further driving the cross plate 21 and the rotating plate 27 to move downward. Then, it will drive the metal pressing roller 281 to contact the outer wall of the can. Then, start the electric slider 122 to drive the placing table 12 to move left and right, and then drive the clamped can to move left and right. Thus, the metal pressing roller 281 can roll on the can, pressing the label to make the label adhere to the can body. Then, start the motor 13, which will drive the short plate 14 and the electric telescopic rod 15 to rotate, and then drive the can body to rotate. The corner parts of the label can also come into full contact with the can body accordingly, so that the corners of the label can also adhere tightly to the can body, ensuring that the label can be completely and firmly attached to the can body, achieving a good fitting effect. After fixing the label, start the motor 13, which will drive the short plate 14 and the electric telescopic rod 15 to rotate, further driving the can to rotate in the U-shaped groove base 18, and then using the sponge block 181 to clean the outer wall of the can;

[0036] The metal pressing roller 281 is used for relatively hard metal labels and arc-shaped products made of metal materials. For soft plastic labels and arc-shaped products made of glass materials, the arc pressing component can adopt a soft rubber pressing wheel 272, which can adapt to the arc shape of the product through elastic deformation, and at the same time avoid scratching the surface of the product. When the rubber pressing wheel 272 needs to be replaced, the nut 261 can be loosened, and then the threaded rod 26 is moved in the direction close to the C-shaped plate 23, driving the sliding plate 25 to move away from the C-shaped plate 23. Then, slide the C-shaped plate 23 away from the rotating plate 27, causing the L-shaped rod 22 to slide along the T-shaped groove 211. Then, rotate the rotating plate 27 and make the rubber pressing wheel 272 rotate to the bottom of the rotating plate 27. Then, slide the C-shaped plate 23 again and make the pressing plate 24 move to the top between the cross plate 21 and the rotating plate 27. Then, move the sliding plate 25 to the bottom between the cross plate 21 and the rotating plate 27. Then, tighten the nut 261 to fix the rotating plate 27 and realize the replacement of the metal pressing roller 281 and the rubber pressing wheel 272.
