Technical Field

[0001] The utility model relates to the technical field of label application, in particular to a floating structure of a label applicator. Background Art

[0002] The instant printing and labeling machine is a printing device suitable for instant printing and labeling of products with flat surfaces, flat corners, and flat arcs. It is suitable for self-adhesive labels and is widely used in electronics, hardware, plastics, chemicals, food, aerospace and other industries. It mainly uses a printer with a peeling device to print the label, and the label and the backing paper behind it are automatically peeled off under the action of the peeling device, and then the applicator drives the label to be automatically attached to the product. During the labeling process of the current applicator, the force of the cylinder of the applicator is directly transmitted to the object to be labeled, and the surface of the object to be labeled will be damaged.

[0003] Therefore, in order to correct the above defects, we propose a floating structure of the label applicator. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a floating structure of a label applicator.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a floating structure of a label applicator, the floating structure includes a mounting sleeve, a circular ring plate is connected to the bottom of the mounting sleeve, the diameter of the circular ring plate is larger than the diameter of the mounting sleeve, a floating plate is provided below the circular ring plate, the bottom of the floating plate is connected to a label palm, the circular ring plate and the floating plate are connected by a plurality of guide rods, the guide rods are fixed to the floating plate, the top of the guide rods slides through the circular ring plate, and a spring is provided between the circular ring plate and the floating plate, and the spring is sleeved on the outside of the guide rods.

[0006] Furthermore, a fixed limiting rod is passed through the annular plate from top to bottom, and when the spring is not compressed, a distance is maintained between the bottom of the limiting rod and the floating plate.

[0007] Furthermore, the circular plate is penetrated from top to bottom by several laser sensors, and the bottom end of the laser sensor passes through the bottom of the circular plate. The upper end of the floating plate is equipped with several sensor contact buffer rubber heads corresponding to the laser sensors one by one, and the sensor contact buffer rubber heads are located directly below the laser sensors.

[0008] Furthermore, a shielding cylinder is installed at the lower end of the annular plate, the lower end of the shielding cylinder is flush with the lower end of the limiting rod, and the outer edge of the shielding cylinder is flush with the outer edge of the annular plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the floating structure can provide a buffer when the label palm is pressed against the product, and a laser sensor is provided. When labeling, the label palm contacts the product, and the label palm will retract under the action of elasticity, playing a buffering role. After the label palm retracts, the distance between the laser sensor and the floating plate changes, the laser sensor sends a signal, and the cylinder stops running. Therefore, the labeling distance can be freely determined. At the same time, the labeling force is gentle and constant, and will not crush the object. It can protect the surface of the labeled object from being damaged, and can adapt to product surfaces of different shapes. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The utility model provides a technical solution:

[0018] See also Figure 1-4, a floating structure of a label applicator, the floating structure includes a mounting sleeve 1, the mounting sleeve 1 is connected to the main structure (cylinder rod) of the label applicator by screws, the bottom of the mounting sleeve 1 is connected to a circular ring plate 2, the diameter of the circular ring plate 2 is larger than the diameter of the mounting sleeve 1, so that the outer ring of the circular ring plate 2 protrudes from the outer ring of the mounting sleeve 1, a floating plate 3 is provided under the circular ring plate 2, the bottom of the floating plate 3 is connected to a label palm 4, the circular ring plate 2 and the floating plate 3 are connected by a number of guide rods 5, the guide rods 5 are fixed to the floating plate 3, the top of the guide rod 5 slides through the circular ring plate 2, and a spring is provided between the circular ring plate 2 and the floating plate 3, the spring is sleeved on the outside of the guide rod 5, in the air Under the action of the cylinder, the circular plate 2, the floating plate 3 and the palm 4 are lowered together. When the palm 4 is pressed on the product, the self-adhesive label is attached to the product. Due to the existence of the guide rod 5 and the spring, the palm 4 will retract, and the guide rod 5 and the circular plate 2 will slide, so that no strong impact will be formed on the product, thereby preventing the product from being hurt and damaged. At the same time, the distance between the floating plate 3 and the laser sensor 7 changes, and the laser sensor 7 sends a signal to the control system of the label applicator. The blowing hole on the label applicator blows air outwards, applying pressure to the self-adhesive label, making it stick tightly to the product. A label is attached, and then the output end of the cylinder retracts, waiting for the next self-adhesive label to be posted.

[0019] In the above, the control system of the label applicator and the like are all prior arts.

[0020] In addition, a fixed limit rod 8 is passed through the circular plate 2 from top to bottom. When the spring is in the uncompressed state, a distance is maintained between the bottom of the limit rod 8 and the floating plate 3. The limit rod 8 is used to limit the retraction distance of the floating plate 3. A number of laser sensors 7 are passed through the circular plate 2 from top to bottom. The bottom end of the laser sensor 7 passes through the bottom of the circular plate 2. A number of sensor contact buffer rubber heads 6 corresponding to the laser sensors 7 are installed on the upper end of the floating plate 3. The sensor contact buffer rubber head 6 is directly below the laser sensor 7. When the floating plate 3 retracts, the sensor contact buffer rubber head 6 can protect the laser sensor 7.
