[0033] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0035] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Embodiment 1:

[0037] A differentiated label paper, combined with Figure 1 , comprising a label paper body 1, a scraping area 2 is arranged on the label paper body 1, an 8-shaped image 3 is arranged on the scraping area 2, and a scrapeable covering layer 4 covering the image is arranged on the outer side of the scraping layer 2.

[0038] A preferred implementation of this embodiment is that a plurality of 8-shaped graphics 3 are arranged in an array along the length direction on the scraping area 2 to form a multi-digit number.

[0039] In specific use, the 8-shaped graphic is like the digital display of existing traffic lights. When the upper and lower vertical bars on the left are scraped off, it represents 1, and when all are scraped off, it represents 8. Scratching off the outer circle and leaving only the middle bar represents 0. It is similar to the red and green digital display, and can display all numbers from 0 to 9. Multiple 8-shaped graphics, such as three 8-shaped graphics, can represent three-digit numbers, thereby effectively distinguishing numbers up to three-digit numbers.

[0040] When in use, you can scrape off the scrape-off cover layer according to your own preferences to display different numbers. When you take a break or leave the meeting, you can find the beverage bottle you are drinking according to your number, avoiding the situation where you cannot accurately distinguish which bottle you are drinking, reducing the situation where drinkers throw away their drinks because they cannot distinguish the bottles they are drinking, and reducing the waste of water resources. Different packaging bottles can meet the needs of dozens or even hundreds of different people in large conferences to distinguish their drinks when using the same packaged beverage.

[0041] When the present invention is implemented, the background color, the image color and the scratchable coating color can be kept in three different colors. It is best to set them to three colors with obvious color differences, such as white background, red image, blue scratchable coating, etc.

[0042] In specific implementation, the overall background is white, with a red 8-shaped logo area printed on it, which can be completed in one process during printing. In the second printing process, the bottom red 8-shaped text is covered with a blue scratchable coating. This is the initial state, that is, a white background with a blue 8-shaped graphic. In specific use, if the number 0 needs to be represented, the outer circle of blue can be scraped off to represent the bottom red 0, or only the middle horizontal bar can be scraped off to represent the blue 0. In the above method, ten red numbers from 0 to 9 can be displayed, and ten blue numbers from 0 to 9 can also be displayed, forming 20 different numbers of different colors, achieving more differentiated effects.

[0043] The present invention also discloses a labeling machine, Figure 2 , 3 , including a support seat 5, a conveying mechanism 6 arranged above the support seat 5, a labeling mechanism 7 is arranged above one side of the conveying mechanism 6, and a bonding mechanism 8 is arranged on the other side thereof, a placing table 9 is arranged on the top of the support seat 5 close to the conveying mechanism 6, and the placing table 9 is a horizontally arranged flat plate, and a feeding column A9-1, a feeding column B9-2, a feeding column C9-3 and a collecting column 9-4 are vertically arranged on the placing table 9, and the feeding columns A9-1, B9-2 and C9-3 are arranged in a herringbone shape, and a hot air mechanism 10 for heating the label paper is arranged in the middle of the feeding columns A9-1, B9-2 and C9-3, and an electric collecting column 9-5 is arranged on the side of the labeling mechanism 7 away from the placing table 9, and a cooling clamping mechanism is arranged on the side of the electric collecting column 9-5 away from the labeling mechanism 7, and the clamping cooling mechanism is used to clamp the label paper and quickly cool the adhesive layer.

[0044] In specific implementation, the packaging bottle is transported from the left to the right by the conveying mechanism. When it is transported to the laminating mechanism, the laminating mechanism presses the packaging bottle onto the labeling mechanism, and the labeling mechanism drives the packaging bottle to rotate and paste the label paper. After the label paper is pasted, the laminating mechanism releases the packaging bottle, and the packaging bottle continues to move forward under the drive of the conveying mechanism. The conveying mechanism transports the packaging bottle to the cooling and clamping mechanism, and the cooling and clamping mechanism clamps the packaging bottle, so that the label paper pasted on the outer ring of the packaging bottle is pasted more firmly. At the same time, the adhesive layer on the label paper is quickly adhered and hardened by blowing cooling, so that it can be pasted on the packaging bottle better and faster to complete the packaging.

[0045] The preferred implementation method of this embodiment is to combine the attached Figure 4 , 5 The labeling mechanism 7 includes a mounting bracket 7-1, on which a labeling motor 7-2 is fixedly arranged, and the output end of the labeling motor 7-2 is transmission-connected to a labeling roller 7-3. In the specific design, the output end of the labeling motor 7-2 is connected to an active tooth, and the labeling roller 7-3 is coaxially connected to a transmission tooth that cooperates with the active tooth. The labeling motor 7-2 is transmission-connected to the labeling roller 7-3 through a gear, and the labeling roller 7-3 is vertically arranged. A support shaft is arranged at the center of the labeling roller 7-3, and one end of the support shaft is rotationally connected to the mounting bracket 7-1 through a bearing. The labeling roller 7-3 rotates with the mounting bracket 7-1 under the drive of the support shaft, and a scraper is arranged on the side of the mounting bracket 7-1 close to the labeling roller 7-3, and the scraper is vertically arranged close to the labeling roller 7-3. The laminating mechanism 8 is arranged in cooperation with the labeling mechanism 7. The laminating mechanism 8 includes a laminating bracket 8-1 arranged above the support seat 5. An electric telescopic rod 8-2 is arranged above the laminating bracket 8-1. The output end of the electric telescopic rod 8-2 is connected to a laminating base 8-3. A pair of rollers 8-4 are vertically rotatably connected to the laminating base 8-3. The rollers 8-4 cooperate with the labeling roller 7-3 to clamp the packaging bottle for easy labeling.

[0046] In specific implementation, the electric telescopic rod drives the fitting base to move, and then drives a pair of rollers to put the packaging bottle close to the labeling roller. The labeling motor drives the labeling roller to rotate, and the rotation of the labeling roller drives the packaging bottle to rotate. At this time, the labeling roller, the packaging bottle, and the roller rotate at the same time, and the label paper wrapped on the labeling roller is attached to the packaging bottle, achieving the technical effect of quickly attaching the label paper to the packaging bottle.

[0047] The long strip with label paper is wound on the collecting column, passed through feeding column A, feeding column B, feeding column C and wound on the labeling roller, and then passed through the labeling roller and wound on the electric collecting column. Figure 6The electric collecting column 9-5 includes a column 9-6 and a collecting motor 9-7. The output end of the collecting motor 9-7 drives the column 9-6 to rotate. The column 9-6 is arranged to rotate vertically, and grooves 9-8 are arranged on both sides. U-shaped clips 9-9 are embedded in the grooves 9-8. The U-shaped clips 9-9 are used to clamp and fix the long strips. The collecting column is designed similarly to the electric collecting column, and it also includes a column 9-6. The column 9-6 is arranged to rotate vertically, and grooves 9-8 are arranged on both sides. U-shaped clips 9-9 are embedded in the grooves 9-8. The U-shaped clips 9-9 are used to clamp and fix the long strips.

[0048] During specific implementation, the electric collecting column drives the long strip to move, and when the long strip with the label paper passes through the labeling roller, the label paper is pasted on the packaging bottle under the drive of the labeling roller.

[0049] The preferred implementation method of this embodiment is to combine the attached Figure 3 The feed column A9-1, feed column B9-2, and feed column C9-3 are all rotatably matched with the placement table 9. The hot air mechanism 10 includes a vertically arranged cylinder 10-1, which is arranged between the feed columns A9-1, B9-2, and C9-3, and its top is closed. The outer ring of the cylinder 10-1 is arrayed in the direction of the feed columns A9-1, B9-2, and C9-3. A plurality of blowing holes 10-2 are arranged in an array in two vertical rows along the axial direction of the cylinder 10-1. The bottom end of the cylinder 10-2 is provided with an air pipe connected thereto, and the other end of the air pipe is connected to the hot air blower. The air pipe is provided with an electromagnetic valve that controls its opening and closing. The electromagnetic valve selects a stop-type electromagnetic control valve for flow control, such as a model: 941H-16C national standard electric stop valve.

[0050] During specific implementation, as the label paper rotates between feed columns A, B and C, the air pipe delivers hot air into the cylinder, and the blowing holes on the cylinder blow hot air toward the label paper, heating and softening the adhesive layer on the label paper, making it easier to stick the label paper on the packaging bottle.

[0051] The preferred implementation method of this embodiment is to combine the attached Figure 7 , 8 The cooling clamping mechanism includes a rolling assembly 11 and a clamping assembly 12 which are respectively arranged at both ends of the conveying mechanism 6 and cooperate with each other. The rolling assembly 11 includes a rolling bracket 11-1 arranged above the support seat 5. The top of the rolling bracket 11-1 is connected to a rolling pressure frame 11-2. A roller motor 11-3 is arranged on one side of the top of the rolling pressure frame 11-2. A pulley 11-4 is arranged at the output end of the roller motor 11-3. The pulley 11-4 is rotatably connected to the rolling pressure frame 11-2, and a roller belt 11-5 is arranged on the outer ring of the pulley 11-4.

[0052] The clamping assembly 12 includes a clamping bracket 12-1 arranged above the support seat 5, and a clamping electric telescopic rod 12-2 is fixedly connected to the clamping bracket 12-1, and a cooling push plate 12-3 is arranged at the output end of the clamping electric telescopic rod 12-2. The cooling push plate 12-3 is vertically arranged, and an exhaust hole 12-4 is arranged on the side close to the rolling assembly 11. The exhaust holes 12-4 are arranged in a plurality of arrays along the side of the cooling push plate 12-3, and a cavity is arranged inside the cooling push plate 12-3, and the cavity is connected to the exhaust hole 12-4. An inflation head 12-5 connected to the cavity is arranged on the rear side of the cooling push plate 12-3, and the inflation head 12-5 is connected to an external air source through an air pipe.

[0053] In specific implementation, the cooling push plate pushes the package onto the roller belt, starts the roller motor, drives the pulley to rotate, and the pulley drives the roller belt to rotate, so that the packaged bottle rolls and moves under the drive of the cooling push plate and the roller belt. During the rolling movement of the packaged bottle, the label paper pasted on it is more firmly pasted under the pressure of the cooling push plate; at the same time, the exhaust holes on the cooling push plate blow out air through the air pipe to cool and harden the adhesive layer of the label paper quickly, making the pasting more firm and reliable. The exhaust holes can blow out cold air or natural air, and natural air is preferred here. The blowing of natural wind makes the cooling of the adhesive layer more natural and the cooling and solidification are better.

A conveying motor 6-4 is arranged on one side of the conveying frame 6-1, and the output end of the conveying motor 6-4 is transmission-connected to one of the supporting rollers 6-2.

[0055] In specific implementation, the conveying motor drives the supporting roller to rotate, and then drives the conveyor belt wrapped around the supporting roller to rotate, so as to achieve the purpose of conveying the packaging bottles. Guardrails are arranged on both sides of the conveying frame to prevent the packaging bottles from falling.

[0056] A preferred implementation method of this embodiment is that a control screen 5-1 is provided on one side of the support base 5, an operation button 5-2 is provided on one side of the control screen 5-1, and a control system is also provided on the support base 5. The control system is electrically connected to the control screen 5-1, the operation button 5-2, the conveying motor 6-4, the labeling motor 7-2, the electric telescopic rod 8-2, the collecting motor 9-7, the roller motor 11-3, and the clamping electric telescopic rod 12-2 through wires or wireless networks.

[0057] When the present invention is implemented, the control system automatically controls the coordinated operation of various components, so as to quickly complete the labeling work of the packaging bottles, thereby achieving better efficiency and saving a lot of manpower and time.

[0058] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
