Description

Technical Field

[0001] This utility model relates to the field of labeling technology, specifically to an automatic labeling machine. Background Technology

[0002] In the field of labeling technology, automatic labeling machines are widely used in product labeling operations. However, existing automatic labeling machines generally have functional limitations. These machines can only complete the feeding and initial application of labels, lacking the function of pressing the label edges after application. This leads to labels affixed to the outer wall of the product easily peeling off during subsequent use, handling, or transportation because the edges are not tightly adhered to the product. This not only affects the integrity of the product's appearance but may also cause the label to fall off, failing to reliably fulfill its functions of identification and information transmission. This causes inconvenience in production and use, and makes it difficult to meet the requirements for high-quality labeling. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 The present invention provides an automatic labeling machine, comprising: an automatic labeling machine body 1, and an installation box 2 mounted on the label conveyor belt of the automatic labeling machine body 1. An installation frame 3 is installed on the inner top wall of the installation box 2, and an electric rotating table 4 is installed on the inner top wall of the installation box 2. A rotating component 5 is rotatably mounted on the inner bottom wall of the installation frame 3, and a conductive slip ring 6 is installed on the outer wall of the rotating component 5. The rotating component of the electric rotating table 4 is connected to the top of the rotating component 5. A first electric push rod 7 and a second electric push rod 8 are respectively installed at both ends of the outer bottom wall of the rotating component 5. A suction cup 9 is installed at the bottom of the piston rod of the first electric push rod 7. An installation plate 10 is installed at the bottom of the piston rod of the second electric push rod 8. A surrounding assembly 11 is rotatably mounted on the outer bottom wall of the installation plate 10. A motor 12 is installed at one end of the outer top wall of the installation plate 10, and the output shaft of the motor 12 is connected to one end of the top of the surrounding assembly 11. A pressing assembly 13 is installed on the outer wall of the surrounding assembly 11.

[0021] It should be noted here that the automatic labeling machine body 1 is the prior art in this application, and its specific structure and working principle will not be described in detail here. All electronic components in the equipment are connected to the control system inside the automatic labeling machine body 1 through signal lines.

[0022] The automatic labeling machine body 1 transports the label to be labeled into the mounting box 2, while the product to be labeled also enters the designated position inside the mounting box 2; the piston rod of the first electric push rod 7 extends and retracts downward, driving the suction cup 9 at the bottom to descend to the label surface, and after the label is adsorbed by the negative pressure of the suction cup, the piston rod of the first electric push rod 7 retracts upward to reset; the electric rotary table 4 starts, driving the rotating part 5 connected to it to rotate 180° around its own axis, transferring the suction cup 9 adsorbing the label to directly above the product; then the first electric push rod 7 descends again, affixing the label to the outer wall of the product, and after the affixing is completed, the first electric push rod 7 rises to reset;

[0023] The electric rotary table 4 drives the rotating component 5 to rotate 180° again, so that the first electric push rod 7 returns to its initial position and is ready to pick up the next label. At this time, the mounting plate 10, which is equipped with the surrounding component 11 and the motor 12, is exactly above the product labeling position. The piston rod of the second electric push rod 8 extends and retracts downward, driving the mounting plate 10 and the bottom surrounding component 11 and pressing component 13 to descend, so that the pressing component 13 fits the edge of the label. At the same time, the motor 12 starts, and the output shaft drives the surrounding component 11 to rotate, which in turn drives the pressing component 13 to make a surrounding motion along the edge of the label, pressing the edge of the label tightly with the outer wall of the product to prevent subsequent edge lifting.

[0024] In a preferred embodiment, the surrounding assembly 11 includes four gear rollers 1101 and a toothed belt 1102 drivenly connected to the four gear rollers 1101.

[0025] It should be noted that when the output shaft of motor 12 drives the rotation of one of the gear rollers 1101 connected to it, the four gear rollers 1101 are connected by a toothed belt 1102. The actively rotating gear roller 1101 drives the other three gear rollers 1101 to rotate synchronously and in the same direction through the meshing transmission of the toothed belt 1102. Finally, the toothed belt 1102 moves stably and cyclically along the trajectory formed by the four gear rollers 1101, providing uniform and continuous circumferential power to the pressing assembly 13 installed on its outer wall, ensuring the stability of the pressing trajectory.

[0026] In a preferred embodiment, the pressing assembly 13 includes a mounting block 1301 mounted on the outer wall of the toothed belt 1102, a connecting rod 1302 mounted on the bottom of the mounting block 1301, an arc-shaped shell 1303 mounted on the bottom of the connecting rod 1302, and a ball bearing 1304 rotatably mounted inside the arc-shaped shell 1303.

[0027] It should be noted here that when the toothed belt 1102 of the surrounding component 11 moves, it drives the mounting block 1301 fixed on the outer wall to move synchronously around; the arc-shaped shell 1303 moves with the mounting block 1301.

[0028] The ball bearing 1304, which is rotatably mounted inside the arc-shaped shell 1303, is in direct contact with the label surface. During the circumferential motion, the ball bearing 1304 rolls along the edge of the label and rolls the edge of the label to achieve a tight adhesion between the label and the product.

[0029] In a preferred embodiment, a fixing rod 1305 is mounted on the top of the mounting block 1301, and a guide block 1306 is mounted on the top of the fixing rod 1305; a surrounding groove 14 is formed on the bottom outer wall of the mounting plate 10, and the guide block 1306 and the inner wall of the surrounding groove 14 form a sliding fit.

[0030] It should be noted that during the movement of the pressing assembly 13, the guide block 1306 is embedded in the surrounding groove 14 at the bottom of the mounting plate 10 and slides along the groove wall of the surrounding groove 14. The groove shape of the surrounding groove 14 is perfectly matched with the "label edge surrounding trajectory". The groove wall limits the movement direction of the guide block 1306, thereby preventing radial displacement of the pressing assembly 13. At the same time, the sliding fit can reduce the resistance when the guide block 1306 moves, ensuring that the pressing assembly 13 can smoothly and evenly complete the surrounding pressing, thus improving the consistency of the pressing effect.

[0031] In a preferred embodiment, the first electric push rod 7, the second electric push rod 8, and the motor 12 are all connected to the inner slip ring rotor of the conductive slip ring 6 via wires.

[0032] It should be noted here that the rotation of the rotating part 5 should be avoided to prevent the wires connecting the first electric push rod 7, the second electric push rod 8 and the motor 12 from getting tangled, broken or losing power, so as to ensure the continuous operation of the equipment.

[0033] Working principle: The automatic labeling machine body 1 transports the label to be labeled into the mounting box 2. At the same time, the product to be labeled enters the designated labeling position in the mounting box 2. The piston rod of the first electric push rod 7 is controlled to extend and retract downward, driving the suction cup 9 installed at its bottom to descend to the label surface. The negative pressure generated by the suction cup 9 adsorbs the label. After adsorption is completed, the piston rod of the first electric push rod 7 retracts upward, driving the suction cup 9 with the label adsorbed to rise and return to its original position. The electric rotating table 4 is started, and its rotating component drives the rotating component 5 connected to it to rotate 180° around its own axis, transferring the suction cup 9 with the label adsorbed from the initial position to directly above the product.

[0034] The piston rod of the first electric push rod 7 is controlled to extend and retract downwards again, causing the suction cup 9 and the label to descend until the label is attached to the outer wall of the product. After the label is attached, the piston rod of the first electric push rod 7 retracts upwards, causing the suction cup 9 to detach from the product and rise back to its original position. The electric rotary table 4 drives the rotating part 5 to rotate 180° again, so that the first electric push rod 7 and the suction cup 9 return to their initial positions, ready to pick up the next label. At this time, the second electric push rod 8 installed at the other end of the bottom of the rotating part 5 and its bottom mounting plate 10 are exactly rotated to be directly above the product labeling position.

[0035] The piston rod of the second electric push rod 8 is controlled to extend and retract downward, causing the mounting plate 10, the surrounding assembly 11 at the bottom of the mounting plate 10, and the pressing assembly 13 to descend synchronously until the pressing assembly 13 is attached to the label edge on the outer wall of the product; the motor 12 at the top of the mounting plate 10 is started, and its output shaft drives one of the gear rollers 1101 in the surrounding assembly 11 to rotate; through the transmission cooperation between the toothed belt 1102 and the four gear rollers 1101, the toothed belt 1102 moves cyclically along a preset trajectory, thereby driving the pressing assembly 13 installed on its outer wall to move around the label edge.

[0036] During the movement, the guide block 1306, which is connected to the top of the mounting block 1301 by the fixing rod 1305, slides in the surrounding groove 14 at the bottom of the mounting plate 10 to ensure the precise trajectory of the pressing component 13; at the same time, the ball bearings 1304 inside the arc-shaped shell 1303 roll into contact with the edge of the label, rolling the edge of the label to achieve a tight adhesion between the label and the product, and to prevent subsequent edge lifting.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
