Description

Technical Field

[0001] This utility model belongs to the field of labeling machine technology, and in particular relates to a label brushing wheel assembly structure for a high-speed labeling machine. Background Technology

[0002] Labeling machines are core packaging equipment in industries such as food and beverage, pharmaceuticals, and daily chemicals. With the increasing diversification of market demands, they not only need to meet the requirements of high-speed production (currently, mainstream equipment reaches 400-600 bottles / minute), but also need to adapt to different bottle and label sizes—from small bottles with diameters of 52mm and 65mm to large bottles with diameters of 100mm. The corresponding label sizes and center column specifications need to be flexibly adjusted to achieve efficient production changeovers. Among these, the label-swiping transmission mechanism, as a key component for precise label placement and application, directly determines the continuous operation capability of the production line and the quality of product packaging through its operational stability and adaptability.

[0003] In traditional structures, gear meshing transmission involves tooth surface contact friction, which can easily lead to tooth tip wear and tooth thickness reduction during long-term high-speed operation. Furthermore, the transmission ratio between gears and belts is fixed, making the adjustment of the relative position of the brush wheel assembly and the central column cumbersome. When production needs change, it is necessary to replace gears, belts, and the central column with corresponding specifications. Adjusting the position of the label roller is also difficult, resulting in not only time-consuming changeovers but also the potential for improper adjustments to further exacerbate transmission deviations, leading to a decrease in the initial packaging qualification rate after the changeover.

[0004] Therefore, a label brushing wheel assembly structure for a high-speed labeling machine is needed for use. Utility Model Content

[0005] This utility model provides a label brushing wheel assembly structure for a high-speed labeling machine to solve the problems in the prior art.

[0006] The present invention adopts the following technical solution: a label brushing wheel assembly structure for a high-speed labeling machine, comprising two symmetrically arranged mounting seats, a label brushing adjustment mechanism between the two mounting seats, the label brushing adjustment mechanism being rotatably connected to the two mounting seats, a label brushing rotation mechanism on the label brushing adjustment mechanism, the label brushing rotation mechanism being rotatably connected to the label brushing adjustment mechanism, and further comprising a label brushing drive mechanism, the label brushing drive mechanism being transmissionally connected to the label brushing rotation mechanism.

[0007] A further technical solution includes a mounting block, an adjusting block, an adjusting screw shaft, and two sliding rods. The two sliding rods are symmetrically arranged between two mounting seats. The two ends of the adjusting screw shaft are rotatably connected to the two mounting seats. The adjusting screw shaft is located between the two sliding rods. A rotating disk is provided at the end of the adjusting screw shaft. The mounting block is fixedly connected to the two sliding rods. The adjusting screw shaft is divided into a smooth rod section and a screw section. The smooth rod section is rotatably connected to the mounting block. The adjusting block is slidably engaged with the two sliding rods. The adjusting block is threadedly connected to the screw section.

[0008] A further technical solution is provided, wherein the label-brushing rotating mechanism includes two first rotating shafts rotatably connected to the mounting block and two second rotating shafts rotatably connected to the adjusting block. The two first rotating shafts are arranged at equal vertical spacing, and the two second rotating shafts are arranged at equal vertical spacing. One end of each first rotating shaft is provided with a first small synchronous pulley and a first large synchronous pulley arranged coaxially. One end of each second rotating shaft is provided with a second small synchronous pulley and a second large synchronous pulley arranged coaxially. A first synchronous belt is sleeved between the two first small synchronous pulleys, and a second synchronous belt is sleeved between the two second small synchronous pulleys.

[0009] In a further technical solution, a first rubber wheel is provided at the other end of the first rotating shaft, and a second rubber wheel is provided at the other end of the second rotating shaft.

[0010] A further technical solution is provided, wherein the marking drive mechanism includes a symmetrically arranged motor base and a mounting plate, a first drive synchronous wheel is provided on the motor base, a second drive synchronous wheel is provided on the mounting plate, a servo motor is provided on the motor base and is connected to the first drive synchronous wheel, and a drive synchronous belt is sleeved between the first drive synchronous wheel, the second drive synchronous wheel, the two first large synchronous wheels and the two second large synchronous wheels.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: Firstly, this utility model innovates the transmission method: it replaces the traditional "gear meshing + multiple belts" with "single drive synchronous belt + four synchronous pulleys". The synchronous belt and synchronous pulleys are in surface contact transmission, resulting in uniform wear and minimal wear (80% less wear compared to point contact wear of gears). Even during long-term high-speed operation (600 bottles / minute), the wear can be controlled within 0.5mm, avoiding the speed difference between the left and right rubber pulleys caused by 1-2mm wear.

[0012] Improved synchronization accuracy: Four large synchronous pulleys are driven by a synchronous belt, with a speed deviation of <0.1%. The left and right offset is controlled within ±0.5mm when the label is lowered. The upper and lower rubber pulleys on the same side are linked by a small synchronous belt, which further ensures that the label is subjected to uniform force, completely solves the problems of label jamming and wrinkling, and reduces the production line downtime failure rate by more than 90%.

[0013] Secondly, in the process of labeling bottles of different specifications, this utility model requires changing the distance between the first and second rubber wheels on the mounting block and the adjusting block. At this time, the rotating disk can be rotated to drive the adjusting screw shaft to rotate on the two mounting seats. The screw section of the adjusting screw shaft rotates on the adjusting block, which will drive the adjusting block to slide horizontally along the two sliding rods, moving closer to or away from the mounting block. When the adjusting block moves, it simultaneously drives the two second rotating shafts and the second rubber wheels to move, so that the distance between the first and second rubber wheels is adjusted from 52mm / 65mm for small bottles to 100mm for large bottles, while ensuring that the positions of the first and second rubber wheels are accurately matched with the center column and the label size.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] The following, in conjunction with the accompanying drawings, details the technical solution of the label brushing wheel assembly structure of a high-speed labeling machine provided by various embodiments of this utility model.

[0017] Reference Figures 1 to 5 As shown in the figure, this utility model embodiment provides a label brushing wheel assembly structure for a high-speed labeling machine, including two symmetrically arranged mounting seats 1, a label brushing adjustment mechanism 2 between the two mounting seats 1, the label brushing adjustment mechanism 2 being rotatably connected to the two mounting seats 1, a label brushing rotation mechanism 3 being provided on the label brushing adjustment mechanism 2, the label brushing rotation mechanism 3 being rotatably connected to the label brushing adjustment mechanism 2, and a label brushing drive mechanism 4 being transmissionally connected to the label brushing rotation mechanism 3.

[0018] It should be noted that a central column is provided between the first rubber wheel 39 and the second rubber wheel 30. The label falls between the first rubber wheel 39 and the second rubber wheel 30 through the central column. The first rubber wheel 39 and the second rubber wheel 30 rotate in opposite directions to generate uniform friction force, which conveys the label downward at a uniform speed and vertically.

[0019] Workflow: Power input: In the brushing drive mechanism 4, the servo motor 45 on the motor base 41 drives the first drive synchronous pulley 43 to rotate, and simultaneously engages the two first large synchronous pulleys 34 and the two second large synchronous pulleys 36 through the drive synchronous belt 46. Synchronous transmission characteristics: The tooth meshing design of the synchronous belt and synchronous pulley avoids the gap error of traditional gear meshing and the slippage problem of belt drive, so that the speed of the four large synchronous pulleys is completely consistent and there is no speed difference.

[0020] Rubber wheel drive: The first large synchronous wheel 34 and the second large synchronous wheel 36 drive the corresponding first rubber wheel 39 and second rubber wheel 30 to rotate synchronously in opposite directions through the first rotating shaft 31 and the second rotating shaft 32. The first rubber wheel 39 rotates clockwise and the second rubber wheel 30 rotates counterclockwise, forming the power for the label clamping and lowering. The label falls between the first rubber wheel 39 and the second rubber wheel 30 through the central column. The synchronous counter-rotation of the first rubber wheel 39 and the second rubber wheel 30 generates uniform friction force, which conveys the label downward at a uniform speed and vertically.

[0021] The two first rubber rollers 39 and second rubber rollers 30 on the same side are linked by the first small synchronous pulley 33 + the first synchronous belt 37 (left side) and the second small synchronous pulley 35 + the second synchronous belt 38 (right side) to ensure that the first rubber rollers 39 and second rubber rollers 30 set at different heights rotate at the same speed, thus avoiding wrinkles on the label due to uneven force on the label. In a specific embodiment, the label adjustment mechanism 2 includes a mounting block 21, an adjustment block 22, an adjustment screw shaft 23, and two slide rods 24. The two slide rods 24 are symmetrically arranged between two mounting seats 1. The two ends of the adjustment screw shaft 23 are rotatably connected to the two mounting seats 1. The adjustment screw shaft 23 is located between the two slide rods 24. The end of the adjustment screw shaft 23 is provided with a rotating disk 25. The mounting block 21 is fixedly connected to the two slide rods 24. The adjustment screw shaft 23 is divided into a smooth rod section 26 and a screw section 27. The smooth rod section 26 is rotatably connected to the mounting block 21. The adjustment block 22 is slidably engaged with the two slide rods 24. The adjustment block 22 is threadedly connected to the screw section 27.

[0022] During the labeling process for bottles of different sizes, it is necessary to change the distance between the first rubber wheel 39 and the second rubber wheel 30 on the mounting block 21 and the adjusting block 22. At this time, the rotating disk 25 can be rotated to drive the adjusting screw shaft 23 to rotate on the two mounting seats 1. The screw section 27 of the adjusting screw shaft 23 rotates on the adjusting block 22, which will drive the adjusting block 22 to slide horizontally along the two sliding rods 24, moving closer to or away from the mounting block 21. When the adjusting block 22 moves, it simultaneously drives the two second rotating shafts 32 and the second rubber wheel 30 to move, so that the distance between the first rubber wheel 39 and the second rubber wheel 30 is adjusted from 52mm / 65mm for small bottles to 100mm for large bottles, while ensuring that the positions of the first rubber wheel 39 and the second rubber wheel 30 are accurately matched with the center column and the label size.

[0023] It should be noted that when adjusting the position of the adjusting block 22, the high-speed labeling machine has a built-in tension adjustment mechanism for adjusting the tension of the drive timing belt 46. This tension adjustment mechanism is existing technology and is not within the scope of protection of this utility model. In a specific embodiment, the label-brushing rotating mechanism 3 includes two first rotating shafts 31 rotatably connected to the mounting block 21 and two second rotating shafts 32 rotatably connected to the adjusting block 22. The two first rotating shafts 31 are arranged at equal vertical spacing, and the two second rotating shafts 32 are arranged at equal vertical spacing. One end of the first rotating shaft 31 is provided with a first small synchronous pulley 33 and a first large synchronous pulley 34 coaxially arranged. One end of the second rotating shaft 32 is provided with a second small synchronous pulley 35 and a second large synchronous pulley 36 coaxially arranged. A first synchronous belt 37 is sleeved between the two first small synchronous pulleys 33, and a second synchronous belt 38 is sleeved between the two second small synchronous pulleys 35. The other end of the first rotating shaft 31 is provided with a first rubber wheel 39, and the other end of the second rotating shaft 32 is provided with a second rubber wheel 30.

[0024] The arrangement of the first synchronous belt 37 and the second synchronous belt 38 ensures the synchronicity of the rotation of the two first rubber rollers 39 and the two second rubber rollers 30; it also ensures that the rotation speeds of the first rubber rollers 39 and the second rubber rollers 30 are consistent, thus preventing the label from wrinkling due to uneven force.

[0025] In a specific embodiment, the marking drive mechanism 4 includes a motor base 41 and a mounting plate 42 symmetrically arranged. The motor base 41 is provided with a first drive synchronous wheel 43, and the mounting plate 42 is provided with a second drive synchronous wheel 44. The motor base 41 is provided with a servo motor 45 that is drively connected to the first drive synchronous wheel 43. A drive synchronous belt 46 is sleeved between the first drive synchronous wheel 43, the second drive synchronous wheel 44, the two first large synchronous wheels 34, and the two second large synchronous wheels 36.

[0026] When power is supplied to the first rubber roller 39 and the second rubber roller 30, the servo motor 45 drives the first drive wheel synchronous pulley to rotate, which in turn drives the second drive synchronous pulley 44, the two first large synchronous pulleys 34 and the two second large synchronous pulleys 36 to rotate via the drive synchronous belt 46. This drives the first rotating shaft 31 and the second rotating shaft 32, which are set up vertically, to drive the corresponding first rubber roller 39 and second rubber roller 30 to rotate synchronously in opposite directions. The first rubber roller 39 rotates clockwise and the second rubber roller 30 rotates counterclockwise, which forms the power for the label to be clamped and lowered. The label falls between the first rubber roller 39 and the second rubber roller 30 through the central column. The synchronous counterclockwise rotation of the first rubber roller 39 and the second rubber roller 30 generates uniform friction force, which conveys the label downward at a uniform speed and vertically.

[0027] The improved transmission system of this invention increases the production capacity of the labeling machine from 320 bottles per minute to 350 bottles per minute, a speed increase of 9.4%. Simultaneously, through the precision design and enhanced stability of the transmission mechanism, the single-machine operating efficiency is increased from 95% to 98%, effectively reducing downtime and scrap rates.

[0028] This invention improves production speed and enhances the stability and accuracy of the labeling process, ensuring excellent labeling quality even at high speeds.

[0029] This invention is applicable to heat shrink labeling of various containers such as PET bottles and glass bottles. It can be widely used in automated packaging production lines in the beverage, food, and daily chemical industries, and has significant economic benefits and promotional value.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
