[0002] The labeling machine is a device that sticks rolled self-adhesive paper labels on PCBs, products or specified packaging. For large barrels of beverages, water or other items, labeling on large barrels is a rather complicated task. Most existing labeling machines use linear labeling machines, that is, the barrel is conveyed by a bottle conveyor chain, and then the self-adhesive paper is removed by a label removal mechanism and pressed on the barrel of the bottle conveyor chain. This type of barrel labeling machine has the following disadvantages: when the barrel is large, such as large barrels of condiments and water on the market, it is difficult to set up the above-mentioned label removal mechanism and labeling structure, and its structure is complex and the labor efficiency is low. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a drum labeling machine, which changes the original linear labeling method and automatically attaches a self-adhesive paper label to the drum body by driving the drum body to rotate, thereby greatly improving labor efficiency.

The plate is provided with a notch for the labeling arm to extend into, and the labeling frame is connected with a barrel driving rod which drives the barrel between the bottle inlet and outlet dial wheel and the labeling arm to lift and lower and can drive the barrel to rotate, and the top of the barrel driving rod is provided with a top pressure head which can lean against the bottom of the barrel, and the barrel lifting rod is driven to lift and lower by the barrel lifting power mechanism connected to the labeling frame and driven to rotate by the rotating power mechanism connected to the labeling frame, and the labeling frame is provided with a barrel pressure rod which can move up and down and can rotate, and the bottom of the barrel pressure rod is provided with a barrel pressure head which is arranged opposite to the top pressure head, and a top spring is provided between the barrel pressure rod and the labeling frame, and the top spring can push the barrel pressure rod downward.

[0005] The labeling frame is provided with a driving box, the barrel driving rod is connected to the driving box through a sliding sleeve and can rotate around its own axis and slide up and down, the rotating power mechanism includes a rotating power machine connected to the labeling frame, a middle transmission shaft that can be connected to the power output shaft of the rotating power machine is rotatably connected in the driving box, and a driven gear is connected to the barrel driving rod; a driving gear is installed on the middle transmission shaft, and the driving gear is always meshed with the driven gear when the barrel driving rod slides up and down, or the middle transmission shaft is provided with a driving gear that meshes with the driven gear when the barrel driving rod slides upward to a set position.

[0006] The barrel lifting power mechanism includes a driving swing arm hinged on the labeling frame, and the labeling frame is equipped with a lifting cylinder. One end of the driving swing arm is dynamically connected to the piston rod of the lifting cylinder, and the other end of the driving swing arm is against the bottom of the barrel driving rod.

[0007] A lower ring platform is arranged at the lower part of the barrel driving rod, and a lower top spring for driving the barrel driving rod to slide downward is arranged at the lower ring platform and the labeling machine frame bracket.

[0008] The labeling frame is provided with a downwardly extending lower arm, the middle part of the driving swing arm is hinged on the lower arm, the downwardly extending piston rod of the lifting cylinder rests against the sink groove of the driving swing arm, and a lifting tension spring located at the lifting cylinder and the lower arm bracket is installed between the driving swing arm and the labeling frame. The labeling frame is also provided with a limit frame, and the limit frame is provided with a slide groove for the driving swing arm to swing.

[0009] The upper part of the labeling machine frame is connected to a barrel pressure rod holder, on which an outer sleeve capable of vertical sliding is mounted, and the barrel pressure rod holder is connected to an adjusting nut threaded on the outer sleeve, and an inner stopper capable of sliding up and down is mounted in the outer sleeve, the top of the barrel pressure rod is rotatably connected to the inner stopper, and the top top spring is located between the inner stopper and the inner top wall of the outer sleeve.

[0011] After adopting the above structure, the barrel body is transported by the bottle conveying chain, and the barrel body runs to the bottle in and out dial wheel. The bottle in and out dial wheel rotates a certain angle, so that the barrel body moves to between the bottle in and out dial wheel and the bottle guard plate under the rotation of the bottle in and out dial wheel. At this time, the labeling arm extends from the notch to the barrel body, and the barrel body lifting rod is lifted up by the power drive of the lifting power mechanism. The top pressure head and the barrel body pressing head cooperate to clamp the barrel body. Under the power drive of the rotating power mechanism, the barrel body rotates, and the self-adhesive paper label on the labeling arm can be automatically attached to the barrel body. After the labeling is completed, the barrel body lifting rod falls, and the bottle in and out dial wheel can transport the labeled barrel body away. The present invention utilizes the characteristics that the barrel body labeling position is mostly located in the thickest part in the middle, and the diameter of the top of the barrel body is generally smaller than the middle position of the barrel body. Therefore, after the barrel body is lifted up, the barrel body is driven to rotate to perform labeling work. The labeling is fast and the labeling position is accurate, which greatly improves the labor efficiency and the labeling quality.

[0012] In summary, the present invention can quickly and automatically label the barrel body, and has the advantages of fast labeling, high labeling quality and high labor efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a drum labeling machine, which includes a labeling frame 1, on which a bottle conveying chain 2 is mounted. The bottle conveying chain 2 can be a conveying chain in the prior art, that is, a conveying roller is coated with a conveying chain, and one of the conveying rollers is connected to a power machine. Its specific detailed structure is a conventional structure for those skilled in the art and will not be described in detail here. The bottle conveying chain 2 is equipped with a bottle in-and-out dial wheel 3 driven to rotate by a bottle in-and-out power mechanism. The bottle in-and-out dial wheel 3 is ringed with a plurality of barrel grooves that can accommodate barrels. In this embodiment, combined with Figure 4 As shown, the bottle in-and-out power mechanism includes a bottle in-and-out power machine 24 connected to the labeling frame 1, and the labeling frame 1 is equipped with a bottle in-and-out power shaft 25 that is power-connected to the bottle in-and-out power machine 24 and vertically arranged, and the bottle in-and-out dial wheel 3 includes a rotating sleeve that is power-connected to the bottle in-and-out power shaft 25 and an upper and lower bottle dial plate connected to the rotating sleeve, and the upper bottle dial plate is provided with a barrel body groove with a ring cloth. The labeling frame 1 is provided with a labeling station 4 located on one side of the bottle inlet and outlet dial wheel 3. The labeling station 4 has a labeling arm 41 extending toward the bottle inlet and outlet dial wheel 3. The specific structure of the labeling station 4 is the prior art. Its basic structure includes a label tube, a label conveying mechanism, etc., and its structure is not described in detail here. The labeling frame 1 is provided with a bottle guard plate 5 corresponding to the bottle inlet and outlet dial wheel 3 and located between the labeling arm and the bottle inlet and outlet dial wheel 3. The bottle guard plate 5 is arranged in an arc shape and is arranged corresponding to the barrel body groove on the bottle inlet and outlet dial wheel 3. A notch is provided on the bottle guard plate 5 for the labeling arm 41 to extend into. When the barrel body is transported to the position of the bottle inlet and outlet dial wheel 3 via the bottle body conveying chain 2, the bottle inlet and outlet dial wheel 3 rotates to drive the barrel body into the position between the bottle inlet and outlet dial wheel and the bottle guard plate 5, thereby preparing for labeling.

[0024] refer to Figures 1 to 3 , and combined with Figure 6 and Figure 7As shown, the labeling frame 1 is connected with a barrel driving rod 7 which drives the barrel body between the bottle inlet and outlet dial wheel and the labeling arm to lift and lower the barrel body and can drive the barrel body to rotate. The top of the barrel driving rod 7 has a top pressure head 71 which can lean against the bottom of the barrel body. The barrel lifting rod 7 is driven to lift and lower by the barrel lifting power mechanism connected to the labeling frame 1 and is driven to rotate by the rotating power mechanism connected to the labeling frame 1. In this embodiment, a drive box 10 is installed on the labeling frame 1, and the barrel driving rod 7 is connected to the drive box through a sliding sleeve and can rotate around its own axis and slide up and down. The rotating power mechanism includes a rotating power machine 11 connected to the labeling frame 1, and a middle transmission shaft 12 that can be connected to the power output shaft of the rotating power machine 11 is rotatably connected in the drive box, and a driven gear 13 is connected to the barrel driving rod 7; a driving gear 14 is installed on the middle transmission shaft 12, and the driving gear is always meshed with the driven gear when the barrel driving rod 7 slides up and down, or the middle transmission shaft 12 is equipped with a driving gear 14 that meshes with the driven gear when the barrel driving rod 7 slides upward to a set position. Figure 6 The structure shown in the figure is that two upper and lower driven gears 13 are arranged on the barrel driving rod 7, and the thickness of the driving gear 14 is much greater than that of the driven gear 13. Therefore, when the barrel driving rod 7 moves up and down, there is always a driven gear 13 meshing with the driving gear 14. Of course, a structure in which only one driven gear 13 is arranged on the barrel driving rod can also be adopted, that is, when the barrel driving rod 7 slides upward to the set position, the driving gear 14 meshes with the driven gear 13, in order to ensure that the barrel driving rod 7 can be accurately driven to rotate, thereby ensuring the labeling quality. The barrel lifting power mechanism includes a driving swing arm 15 hinged on the labeling frame 1, and a lifting cylinder 16 is installed on the labeling frame 1. One end of the driving swing arm 15 is connected to the piston rod of the lifting cylinder 16, and the other end of the driving swing arm is close to the bottom of the barrel driving rod. The lower part of the barrel driving rod 7 is provided with a lower ring platform 72, and the lower ring platform 72 and the bracket of the labeling frame 1 are equipped with a lower top spring 17 that drives the barrel driving rod to slide downward. When the lifting cylinder 16 drives the barrel driving rod 7 to slide upward, the lower top spring 17 is compressed. After the barrel driving rod 7 drives the barrel to rotate, the lifting cylinder 16 no longer drives the barrel driving rod, and the top pressure of the lower top spring 17 causes the barrel driving rod to return to its position. The labeling frame 1 has a lower arm extending downward, and the middle part of the driving swing arm 15 is hinged on the lower arm. The piston rod extending downward of the lifting cylinder 16 is against the sink groove of the driving swing arm 15. A lifting tension spring 18 located between the lifting cylinder 16 and the lower arm bracket is installed between the driving swing arm 15 and the labeling frame 1. The labeling frame 1 is also equipped with a limit frame 19, and the limit frame 19 is provided with a slide groove for the driving swing arm 15 to swing. The above structure makes the lifting and lowering of the barrel driving rod 7 more stable and reliable, thereby ensuring the labeling quality.

[0025] refer to Figures 1 to 3 , and combined with Figure 5As shown, the labeling frame 1 is provided with a barrel pressure rod 8 which can move up and down and rotate, and the bottom of the barrel pressure rod 8 is provided with a barrel pressure head 81 set for the top pressure head 71, and a top top spring 9 is provided between the barrel pressure rod 8 and the labeling frame 1, and the top top spring can push the barrel pressure rod 8 downward, and the upper part of the labeling frame 1 is connected to a barrel pressure rod holder 20, and the barrel pressure rod holder 20 is provided with an outer sleeve 21 which can slide vertically, and the barrel pressure rod holder 20 is connected with an adjusting nut 22 screwed on the outer sleeve 21, and the outer sleeve 21 is provided with an inner plug-in block 23 which can slide up and down, and the top of the barrel pressure rod 8 is rotatably connected to the inner plug-in block, and the top top spring 9 is located between the inner plug-in block 23 and the inner top wall of the outer sleeve 21. When the barrel driving rod 7 of the above structure slides upward, the top pressure head 71 drives the barrel to move upward, and the top of the barrel rests on the barrel pressing head 81. At this time, the top top spring 9 is compressed. When the barrel driving rod 7 rotates, the barrel pressing rod 8 rotates together with the barrel driving rod and the barrel to label. After the labeling is completed, the barrel driving rod 7 slides downward, the top of the barrel is separated from the barrel pressing head 81, and the barrel pressing rod 8 returns to its original position under the top pressure of the top top spring 9. The barrel pressing rod holder 20 of the above structure can not only ensure the vertical sliding of the barrel pressing rod 8, that is, the sliding connection of the outer sleeve 21 to the barrel pressing rod holder, so that the barrel pressing rod 8 and the outer sleeve 21 slide vertically together, and when the adjusting nut 22 is screwed, the outer sleeve 21 will inevitably slide up and down, thereby driving the barrel pressing rod 8 and the barrel pressing head 81 to slide up and down, that is, the height of the barrel pressing head 81 can be adjusted, so that the present invention is applicable to barrels of different heights, which increases the scope of application of the present invention.

[0026] The present invention may also have other embodiments, and other technical solutions formed in the claims will not be described one by one. The present invention is not limited by the above embodiments, and equivalent changes and component replacements based on the above embodiments of the present invention are all within the protection scope of the present invention.
