Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically to an automatic labeling device for bottles. Background Technology

[0002] Automatic labeling equipment is a highly efficient automated machine used in the packaging industry, capable of accurately labeling bottles of various shapes. This equipment typically consists of a conveyor belt system, a label winding system, and labeling components. An intelligent control system enables automatic detection, label placement, and automatic labeling. Its working principle is that when a bottle enters the equipment, sensors detect it, and the control system issues commands to complete a series of actions including label feeding, positioning, cutting, and labeling. Automatic labeling equipment offers advantages such as high speed and stability, ease of operation, and low maintenance costs, significantly improving production efficiency, reducing manual labor, and ensuring label adhesion accuracy and consistency.

[0003] The authorization announcement number CN222572784U discloses an automatic labeling machine for beverage bottles. According to its instruction manual and drawings, the beverage bottle is cleaned and then conveyed forward by a feeding conveyor belt to a position between the labeling roller and the positioning cylinder. The output end of the positioning cylinder extends and pushes the beverage bottle close to the labeling roller through a fixed plate and a connecting plate. The labeling roller rotates, thereby driving the beverage bottle to rotate and perform labeling on the beverage bottle body.

[0004] Using this structure to label bottles still has limitations. The method of applying labels after clamping requires a high degree of flatness of the bottle surface. Uneven bottles may result in poor label adhesion. Furthermore, the method of applying labels after clamping is inefficient and causes inconvenience during production. Summary of the Invention

[0005] This invention addresses the problems encountered when labeling bottles by proposing an automatic labeling device. The device uses a label drive wheel to move the label conveyor belt, thereby effectively applying the label from the shaft surface to the bottle surface. This process is not limited by the surface roughness of the bottle. After the initial labeling, the label only needs to be properly heated to adhere firmly to the bottle surface.

[0006] The purpose of this invention is achieved through the following technical solution: an automatic labeling device for bottles, comprising a device frame, wherein the device frame is provided with a conveying mechanism and a labeling mechanism capable of labeling bottles on the surface of the conveying mechanism from top to bottom, a transmission mechanism that can adjust the transmission direction at multiple angles is connected to one side of the labeling mechanism, a drive mechanism is connected to one end of the transmission mechanism, and bottle limiting mechanisms that prevent bottles from falling are provided on both sides of the conveying mechanism.

[0007] Preferably, the conveying mechanism includes a conveying base, a conveying support frame, a conveying drive shaft, a bottle conveyor belt, and a first drive motor.

Several conveying drive shafts are provided on both sides of the conveying support frame. The surface of the conveying drive shaft is provided with a bottle conveyor belt. At least one conveying drive shaft is connected to the first drive motor at its end.

[0008] Preferably, the bottle conveyor belt is composed of several conveyor support plates that are hinged together end to end. The conveyor support plates are made of plastic. This arrangement is to provide better friction for the bottle conveyor belt when conveying bottles.

[0009] Preferably, the bottle limiting mechanism includes an adjusting support block, a support screw, a locking knob, and a bottle baffle. One side of each adjusting support block is installed on both sides of the conveying support frame. The internal thread of the adjusting support block is connected to the support screw, and the other side of the adjusting support block is also threaded to the locking knob. Changing the position of the end of the locking knob can tighten or loosen the support screw. The side of the support screw closest to the bottle conveyor belt is provided with a bottle baffle.

[0010] Preferably, the labeling mechanism includes a labeling support plate, a rotating shaft support sleeve, a labeling rotating shaft, and a labeling rotating shaft. A plurality of rotating shaft support sleeves are provided on one side surface of the labeling support plate. Each rotating shaft support sleeve has a labeling rotating shaft inside. Each labeling rotating shaft has a labeling drive wheel on its surface. Adjacent labeling drive wheels are connected by a label conveyor belt. A label placement shaft is provided between the label conveyor belts.

[0011] Preferably, the surface of the label support plate is also provided with a tension support plate, the surface of the tension support plate is provided with a plurality of tensioning shafts, each tensioning shaft is provided with a tensioning wheel, and the surface of each tensioning wheel can fit against one side of the label conveyor belt.

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figure 1 and Figure 3 As shown, an automatic labeling device for bottles includes a frame 1 composed of several profiles fixedly connected to each other, and a conveying mechanism 2 is provided inside the frame 1. The conveying mechanism 2 is used to continuously convey the bottles to be labeled.

[0024] The conveying mechanism 2 includes a conveying base 21, a conveying support frame 22, a conveying drive shaft 23, a bottle conveyor belt 24, and a first drive motor 25. The conveying base 21 is disposed on the inner surface of the equipment frame 1. The conveying support frame 22 is connected to the surface of the conveying base 21. Several conveying drive shafts 23 are provided on both sides of the conveying support frame 22. The bottle conveyor belt 24 is provided on the surface of the conveying drive shaft 23. The first drive motor 25 is connected to the end of at least one conveying drive shaft 23. The bottle conveyor belt 24 is composed of several conveying support plates 241 hinged together end to end. The conveying support plates 241 are made of plastic.

[0025] The first drive motor 25 can drive the conveyor drive shaft 23 to rotate during rotation. Gears are engaged on the surface of the conveyor drive shaft 23. These gears are engaged in the grooves at the bottom of several conveyor support plates 241. Therefore, the conveyor drive shaft 23 can drive the entire bottle conveyor belt 24 to move during rotation.

[0026] In this embodiment, please refer to Figure 2As shown, the conveying mechanism 2 is provided with bottle limiting mechanisms 6 on both sides to prevent bottles from falling. The bottle limiting mechanism 6 includes an adjusting support block 61, a support screw 62, a locking knob 63, and a bottle baffle 64. One side of each adjusting support block 61 is installed on both sides of the conveying support frame 22. The internal thread of the adjusting support block 61 is connected to the support screw 62, and the other side of the adjusting support block 61 is also threaded with a locking knob 63. Changing the position of the end of the locking knob 63 can tighten or loosen the support screw 62. The side of the support screw 62 near the bottle conveyor belt 24 is provided with a bottle baffle 64.

[0027] The bottle baffle 64 is used to prevent the bottle from falling off the surface of the bottle conveyor belt 24 during the labeling process. When it is necessary to adjust the height of the bottle baffle 64, loosen the locking knob 63 to release the locking of the support screw 62, then adjust the height of each support screw 62, and then re-tighten the locking knob 63 to adjust the height of the bottle baffle 64.

[0028] In this embodiment, please continue to combine Figure 2 , Figure 5 and Figure 6 As shown, the labeling mechanism 3, which labels the bottles on the surface of the conveying mechanism 2 from top to bottom, includes a labeling support plate 31, a rotating shaft support sleeve 32, a labeling rotating shaft 33, and a labeling drive wheel 34. A plurality of rotating shaft support sleeves 32 are provided on one side surface of the labeling support plate 31. Each rotating shaft support sleeve 32 has a labeling rotating shaft 33 inside. Each labeling rotating shaft 33 has a labeling drive wheel 34 on its surface. Adjacent labeling drive wheels 34 are connected by a label conveyor belt 35. A label placement shaft 36 is provided between the label conveyor belts 35.

[0029] The label support plate 31 is further provided with a tension support plate 37. The tension support plate 37 is provided with a plurality of tensioning shafts 38. Each tensioning shaft 38 is provided with a tensioning wheel 39. The surface of each tensioning wheel 39 can be attached to one side of the label conveyor belt 35.

[0030] The labels sliding down the surface of the label placement shaft 36 have been sheared and adjusted before being pressed by the label conveyor belt 35. At this time, when the bottle on the bottle conveyor belt 24 is conveyed to directly below the label placement shaft 36, each label drive wheel 34 is driven by the label shaft 33, causing the label drive wheel 34 to rotate at high speed, rapidly dropping the labels between the label conveyor belts 35 on both sides onto the bottle surface. During operation, each tension wheel 39 tensions the bottle conveyor belt 24, enabling it to press firmly against the outer surface of the label.

[0031] In this embodiment, a transmission mechanism 4 with adjustable transmission direction at multiple angles is connected to one side of the labeling mechanism 3, and a drive mechanism 5 is connected to one end of the transmission mechanism 4. The transmission mechanism 4 includes a transmission component support frame 41, sliding guide rods 42, metal sliders 43, a first cylinder 44, and a cross-shaft universal coupling 45. The transmission component support frame 41 has several sliding guide rods 42 inside, and a metal slider 43 is slidably connected to the surface of each sliding guide rod 42. Each metal slider 43 is connected to the other side of the labeling support plate 31. The two ends of the first cylinder 44 are respectively connected to the sides of different labeling support plates 31. The distance between adjacent labeling support plates 31 is controlled by the piston rod of the first cylinder 44. One end of the bottom rotating shaft support sleeve 32 is connected to a cross-shaft universal coupling 45, and each cross-shaft universal coupling 45 is connected to the drive mechanism 5.

[0032] The drive mechanism 5 includes a drive support frame 51, a gear support plate 52, a drive gear 53, and a second drive motor 54. The drive support frame 51 is internally connected to the gear support plate 52. A plurality of mutually engaging drive gears 53 are provided on one side of the gear support plate 52. At least one drive gear 53 is connected to the end of the second drive motor 54.

[0033] In actual production, due to differences in label material and thickness, it is necessary to adjust the distance between adjacent label support plates 31. The piston rod of the first cylinder 44 can change the distance between adjacent label support plates 31 when it extends and retracts. During the movement of the label support plate 31, the metal slider 43 plays a supporting and guiding role, sliding on the surface of the sliding guide rod 42.

[0034] Because the position of the label support plate 31 changes, the position of the label rotating shaft 33 also changes accordingly. However, during this process, the universal joint 45 can change its angle, thereby maintaining the transmission relationship with the label rotating shaft 33. The rotating shaft of the second drive motor 54 can drive one of the drive gears 53 to rotate during rotation, thus causing each drive gear 53 to rotate. The drive gears 53 drive each label rotating shaft 33 to rotate via the universal joint 45.

[0035] Working principle and usage of this utility model:

[0036] The rotating shaft of the first drive motor 25 drives the conveyor drive shaft 23 to rotate during its rotation, which in turn drives the entire bottle conveyor belt 24 to move. The bottle conveyor belt 24 is used to transport the bottles to be labeled to the bottom of the label placement shaft 36.

[0037] Next, the labels sliding down the surface of the label placement shaft 36 have been cut and adjusted before being pressed by the label conveyor belt 35. At this time, when the bottle on the surface of the bottle conveyor belt 24 is conveyed to directly below the label placement shaft 36, the rotating shaft of the second drive motor 54 drives one of the drive gears 53 to rotate, thereby causing each drive gear 53 to rotate. The drive gears 53 drive each label sleeve shaft 33 to rotate via a cross-shaft universal coupling 45.

[0038] Finally, the label drive wheel 34 is driven by the label shaft 33, and the label drive wheel 34 rotates at high speed, causing the labels between the label conveyor belts 35 on both sides to fall quickly down and land on the surface of the bottle. During operation, each tension wheel 39 is used to tension the bottle conveyor belt 24, so that the bottle conveyor belt 24 can press the outer surface of the label.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
