Description

Technical Field

[0001] The utility model relates to the technical field of labeling, in particular to a device for attaching anti-counterfeiting labels to plastic cans. Background Art

[0002] A plastic jar anti-counterfeiting label is a special mark attached to the surface of a plastic jar to verify and confirm the authenticity and true source of the product to prevent the emergence of counterfeit and inferior products. This label usually has a unique identification code or logo that can be verified by scanning or other means. The anti-counterfeiting label on the plastic jar may also include other security features, such as anti-counterfeiting marks, anti-counterfeiting patterns or special materials to ensure that it is difficult to forge. With anti-counterfeiting labels, consumers can have greater confidence when purchasing products, while manufacturers can also protect their brand reputation and product quality;

[0003] The existing anti-counterfeiting label attaching device for plastic cans needs to push the can body delivered to the labeling mechanism inward when labeling, so that the can body and the pressure roller rotate and squeeze each other, so that the anti-counterfeiting label can be pressed by the pressure roller when the label is attached to the surface of the can body, so that the protective label can be tightly attached to the surface of the can body. However, the guide rollers on the existing pushing structure are usually fixed to the telescopic end of the telescopic structure by bolts, so it is difficult to adjust the size between the guide rollers when feeding. It is difficult to ensure the accuracy of pushing for larger or smaller can bodies, which makes the can body easy to deviate during the pushing process, making it difficult to ensure the labeling and pressing effects, thereby reducing the labeling quality. For this reason, we propose an anti-counterfeiting label attaching device for plastic cans. Utility Model Content

The mounting frame 4 includes a mounting block, a mounting rod horizontally sleeved on the inner side of the mounting block, and a bolt for fastening at the upper end of the mounting rod. Loosening the bolts allows the mounting rod to move back and forth under the limit of the mounting block, thereby adjusting the front and back distance of the side frame 5, so that the side frame 5 can adapt to the limit use during different tank transportation within a certain range during adjustment, effectively reducing the limitations of the device when used.

[0022] Among them, the pushing assembly 11 includes a connecting frame 111, an electric telescopic rod 112, a connecting plate 113, a fixed frame 116 and a pushing roller 117. The upper end of the surface of the connecting frame 111 is detachably nested with the electric telescopic rod 112 through a bolt, and the telescopic end of the electric telescopic rod 112 passes through the connecting frame 111 and extends to the inner side of the connecting frame 111. The telescopic end of the electric telescopic rod 112 is detachably connected to the connecting plate 113. A connecting slider 118 is horizontally provided on the surface of the connecting plate 113. Fixed frames 116 are slidably provided at both ends of the surface of the connecting chute 115. A pushing roller 117 is vertically rotated on the inner side of the fixed frame 116. An adjusting assembly is provided in the inner cavity of the connecting chute 115. The adjusting assembly includes an adjusting motor 114, a connecting slider 118 and a driving screw 119. A driving screw 119 is provided in the inner cavity of the connecting chute 115 for horizontal rotation. The surfaces of both ends of the driving screw 119 are threadedly connected to the connecting slider 118, and the outer The side wall is fixedly connected to the back of the fixing frame 116, and an adjusting motor 114 is detachably provided on one side of the connecting plate 113, and the power output end of the adjusting motor 114 passes through the connecting plate 113 and extends to the inner cavity of the connecting slide 115 and is fixedly connected to one end of the driving screw 119; a laser sensor is provided at the center position of the upper and lower ends of the inner wall of the connecting plate 113. When the can body moves between the pushing roller 117 and the pressing roller 10, the laser sensor provided on the inner wall of the connecting plate 113 automatically senses the can body and transmits the signal to the control terminal. The control terminal automatically controls the electric telescopic rod 112 on the connecting frame 111 to push the inner pushing roller 117 to move toward the pressing roller 10, thereby pushing the plastic can body on the conveyor belt 6 to fit with the pressing roller 10, thereby effectively labeling and pressing the can body, improving the labeling quality, and the driving screw 119 is a double-threaded screw, which can drive the connecting sliders connected at both ends of the surface to move toward or relative to each other during the rotation process.

[0023] Among them, the laser rangefinder 12 and the baffle 13 are detachably connected at the corresponding positions on the inner side of the fixing frame 116 at both ends of the connecting plate 113; the laser rangefinder 12 generates laser pulses when working, and emits the generated laser pulses through the optical path system. The laser pulses propagate at high speed in the air, and the laser pulses intersect with the baffle 13. At this time, part of the laser energy is absorbed by the target object, and part of the laser energy is reflected back by the target object. The laser rangefinder 12 is equipped with a receiver and a detector to receive the reflected laser signal. By measuring the time difference between the emitted laser pulse and the received reflected laser pulse, the laser rangefinder 12 can calculate the distance from the laser to the target object, and calculate the distance value based on the speed of light and the time difference. Then, when the push roller 117 is adjusted, the distance between the roller bodies can be accurately understood in real time, reducing the difficulty of adjustment and improving the adjustment efficiency.

[0024] Among them, the labeling component includes a collecting roller 7, a baffle 8, a conveying roller 9 and a pressure roller 10. A pressure roller 10 is rotatably provided at the center position of one side of the side frame 5 and at a position corresponding to the pushing component 11. A feed roller is vertically rotated on the upper surface of the workbench 1 on the back of the pressure roller 10. A baffle 8 is detachably provided on one side of the pressure roller 10. Conveying rollers 9 and collecting rollers 7 are vertically rotated on both sides of the end of the baffle 8. The collecting roller 7, conveying roller 9 and the bottom of the pressure roller 10 are all equipped with drive motors, so that the labels can be transported, pressed and waste label paper can be recycled during the rotation process during labeling.

[0025] Among them, the inner walls of the side frames 5 are all laterally fixedly connected with arc rods; the arc rods can reduce the friction coefficient of the inner side of the side frames 5, so that the can body can slide smoothly on the inner side of the side frames 5 under the drive of the conveyor belt 6, ensuring the stability of feeding.

[0026] It should be noted that the present invention is a device for attaching anti-counterfeiting labels to plastic cans. When labeling, the plastic can body is placed vertically on the conveyor belt 6, and the can body is transported by the conveyor belt 6. During the transportation process, the can body is limited by the side frame 5 to avoid the can body from deflecting and ensure the stability of transportation. When the can body moves between the pushing roller 117 and the pressing roller 10, the sensor provided on the inner wall of the connecting plate 113 automatically senses the can body and transmits the signal to the control terminal, which automatically controls the electric telescopic rod 112 on the connecting frame 111 to push the inner side of the can body. The pushing roller 117 moves toward the pressure roller 10, thereby pushing the plastic can body on the conveyor belt 6 to fit with the pressure roller 10, and the driving motors respectively provided at one end of the pressure roller 10, the conveying roller 9 and the collecting roller 7 will drive the three to rotate respectively. During the rotation process, the protective label belt on the surface of the conveying roller 9 is conveyed outward, and under the guidance of the baffle 8, the surface is attached to the surface of the can body, and the excess waste paper will be recovered by the collecting roller 7. The labeled label will be tightly attached to the surface of the can body under the pressure of the pressure roller 10, effectively avoiding falling off, thereby improving the attachment effect of the protective label.
