Description

Technical Field

[0001] This utility model relates to the field of cosmetic bottle packaging, and in particular to a labeling machine suitable for labeling cosmetic bottles. Background Technology

[0002] Cosmetic bottles are packaging containers that achieve isolation through specific materials and structural designs. The main materials include plastics (such as ABS, PP, and PET) and glass. Plastics are environmentally friendly, while glass is mostly used for creams and ointments that need to be stored away from light. Moreover, the design of cosmetic bottles must take into account multiple factors such as protecting the activity of ingredients, ease of use, and environmentally friendly disposal. The bottle opening design must match the product form, such as wide-mouth bottles for solid ointments and narrow-mouth bottles for liquid products.

[0003] To ensure consumers have access to comprehensive and accurate product information and to guarantee safe use, labels on cosmetic packaging are crucial. Labeling cosmetic bottles requires labeling machines, and in automated labeling processes, cosmetic round bottles exhibit significant size diversity, with different product bottle diameters such as small-capacity serum bottles and large-capacity lotion bottles. Traditional labeling machines have several shortcomings: First, the positioning roller spacing is fixed, only suitable for round bottles of a single diameter. Changing bottle types requires disassembling and replacing the roller assembly, which is cumbersome and time-consuming. Second, the round bottle conveyor before labeling lacks an automatic bottle-separating structure, easily leading to multiple bottles piling up and being squeezed, such as partial blockage of the conveyor belt. This can cause bottle misalignment, label misalignment (e.g., uneven label height, wrinkles), and even equipment jamming, affecting production continuity and labeling quality.

[0004] To address this issue, we propose a labeling machine suitable for labeling cosmetic bottles. Utility Model Content

[0008] Furthermore, the height adjustment mechanism includes a mounting frame fixedly connected to the conveying mechanism. The inner wall of the mounting frame is fixedly connected to two guide columns and a threaded rod. The outer surfaces of the two guide columns are slidably connected to an adjusting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The technical solution provided by this utility model has at least the following technical effects or advantages:

[0017] 1. This utility model uses a positioning mechanism with an adjustment mechanism that drives a bidirectional screw via a servo motor to move two transmission screw plates synchronously closer or further apart, achieving precise adjustment of the positioning clamping roller spacing. No parts need to be disassembled. It can be adapted to labeling cosmetic round bottles of different diameters. Furthermore, the guide strip and circular column ensure that the clamping rollers remain parallel during adjustment, preventing bottle rotational offset due to roller skew. Labeling position accuracy is significantly improved, and its adaptability covers mainstream cosmetic round bottle sizes, achieving adaptive clamping roller spacing and accommodating multiple bottle sizes.

[0018] 2. This utility model uses a bottle-separating star wheel of the bottle-separating mechanism, which rotates under the drive of a bottle-separating drive motor. In conjunction with the ring-shaped bottle-separating elastic rollers, it can separate the round bottles piled up on the conveyor belt one by one. The circular slide rail ensures that the bottle-separating star wheel rotates smoothly, avoiding the bottles from tipping over due to the star wheel shaking. Compared with the traditional non-separating structure, the round bottle accumulation rate is greatly reduced, the risk of assembly line jamming is greatly reduced, and automatic bottle separation and anti-accumulation are achieved, ensuring smooth conveying.

[0019] 3. This utility model uses a height adjustment mechanism to adjust the height of the positioning mechanism via a threaded rod, ensuring that the positioning clamping roller is always aligned with the center of the bottle. It can adapt to round bottles of different heights. The side guide plate of the guiding mechanism corrects the conveying direction of the bottle and prevents the bottle from tilting. The elastic labeling roller of the labeling mechanism and the positioning clamping roller are arranged in a triangle to ensure that the label adheres tightly. The multi-structure collaboration improves the labeling accuracy. Attached Figure Description

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example 1:

[0030] Please see Figure 1-7This utility model discloses a labeling machine suitable for labeling cosmetic bottles, comprising a conveying mechanism 1. A label traction mechanism 12 and a label covering mechanism 9 are mounted on the back of the conveying mechanism 1. A guiding mechanism 10, a bottle separating mechanism 11, and a height adjustment mechanism 7 are respectively mounted on the front of the conveying mechanism 1. The height adjustment mechanism 7 includes a mounting frame 71 fixedly connected to the conveying mechanism 1. Two guide posts 72 and a threaded rod 73 are fixedly connected to the inner wall of the mounting frame 71. An adjusting plate 74 is slidably connected to the outer surfaces of the two guide posts 72. The adjusting plate 74 is threadedly connected to the threaded rod 73 and fixedly connected to a positioning mechanism 8. The height adjustment mechanism 7 adjusts the height of the adjusting plate 74 via the threaded rod 73. The dynamic positioning mechanism 8 lifts and lowers synchronously. The threaded rod 73 has a self-locking function to ensure stability after adjustment and to ensure that the positioning clamping roller 83 is always aligned with the center of round bottles of different heights. This avoids unstable bottle rotation and label offset caused by misalignment of the clamping roller height. The position of the positioning mechanism 8 can be adjusted according to the round bottles of different heights that need to be labeled. The bottle separating mechanism 11 is located to the right of the guide mechanism 10. The positioning mechanism 8 is installed on the outer surface of the height adjustment mechanism 7. The positioning mechanism 8 includes a drive cylinder 81. Before use, the drive cylinder 81 must be connected to the corresponding air source to ensure sufficient power. The output end of the drive cylinder 81 is fixedly connected to a transmission box 82. Two positioning clamping rollers 83 are provided on the outer surface of the transmission box 82. An adjustment mechanism 13 is installed internally. The adjustment mechanism 13 includes a servo motor 131 fixedly connected to the transmission box 82. A bidirectional screw 132 is fixedly connected to the output end of the servo motor 131. Two transmission screw plates 133 are threadedly connected to the outer surface of the bidirectional screw 132. One end of each transmission screw plate 133 is fixedly connected to the outer surface of the positioning clamping roller 83. A guide strip 135 is fixedly connected to the upper surface of the transmission box 82, and the positioning clamping roller 83 is slidably connected to the guide strip 135. The servo motor 131 can drive the bidirectional screw 132 to rotate, thereby causing the transmission screw plates 133 to move the positioning clamping roller 83 under the action of the screw threads. This allows the positioning clamping roller to be adjusted according to the size of different cosmetic round bottles. The 83-inch spacing, with no disassembly throughout the process, improves the labeling positioning quality. The upper surface of the adjusting tray 74 is fixedly connected to two fixed cylinders 14, and each fixed cylinder 14 has a sliding rod 15 slidably connected inside. One end of each sliding rod 15 is fixedly connected to the outer surface of the transmission box 82. A circular column 134 is fixedly connected to the front of the transmission box 82, and each transmission screw plate 133 is slidably connected to the circular column 134. The fixed cylinders 14 and sliding rods 15 limit the displacement of the transmission box 82, ensuring the stability of the transmission box 82. Furthermore, the circular column 134 ensures that the transmission screw plate 133 drives the positioning clamping roller 83 to always be parallel and without left or right tilt when adjusting, avoiding the bottle body rotation offset caused by the clamping roller tilting, and further ensuring labeling accuracy.

[0031] The bottle-separating mechanism 11 includes a support frame 111 fixedly connected to the conveying mechanism 1. A bottle-separating drive motor 112 is mounted on the outer surface of the support frame 111. A bottle-separating star wheel 114 is fixedly connected to the output end of the bottle-separating drive motor 112. A ring-shaped arrangement of bottle-separating elastic rollers 115 is mounted on the inner wall of the bottle-separating star wheel 114. A circular slide rail 113 is fixedly connected to the upper surface of the support frame 111. The slider inside the circular slide rail 113 is connected to the bottle-separating star wheel 114. Under the action of the rotating bottle-separating drive motor 112, the bottle-separating star wheel 114 separates the round bottles piled on the conveyor belt 102 into individual bottles and transports them in an orderly manner to the positioning clamping roller 83, thereby improving the continuity of subsequent labeling.

[0032] Example 2:

[0033] The conveying mechanism 1 includes a conveying frame 101, inside which a conveyor belt 102 is installed. A conveyor drive motor 103 is mounted on the outer surface of the conveying frame 101 to drive the conveyor belt 102 to rotate. The conveyor drive motor 103 of the conveying mechanism 1 drives the conveyor belt 102 to run at a uniform speed, providing stable conveying power for bottle separation and labeling. The conveying frame 101 ensures that the conveyor belt 102 is flat, preventing bottle tilting due to wrinkles in the conveyor belt 102, thus laying a stable foundation for subsequent bottle separation and positioning labeling. Two sets of connecting seats 2 are fixedly connected to the bottom surface of the conveying frame 101. Support seats 3 are fixedly connected to the bottom surfaces of multiple sets of connecting seats 2. The connecting seats 2 and support seats 3 enhance the overall stability of the conveying mechanism 1, preventing equipment vibration during labeling from causing the conveyor belt 102 to shift. As the bottle sways, the support base 3 raises the equipment, facilitating the subsequent installation of components such as the intelligent controller 4 and the receiving frame 5, thus optimizing the production line layout. The intelligent controller 4 is installed on the upper surface of the support base 3, and the receiving frame 5 is located on the right side of the support base 3. A side guardrail 6 is installed at the top of the receiving frame 5. The intelligent controller 4 has a built-in PLC controller with high reliability and anti-interference capabilities. It is a known technology and is widely used in industrial automation control. It is electrically connected to various electrical components in this utility model. The intelligent controller 4 can preset labeling parameters for different bottle types, such as the clamping roller spacing, conveying speed, and labeling pressure. It can be called up with one click when changing production, without the need for manual adjustment. The receiving frame 5 collects the labeled round bottles, and the side guardrail 6 prevents the bottles from falling, realizing automated labeling and receiving, and reducing manual intervention.

[0034] The labeling mechanism 9 includes a connecting frame 91 fixedly connected to the conveying mechanism 1. A rotary motor 92 is installed inside the connecting frame 91. An elastic labeling roller 93 is fixedly connected to the output end of the rotary motor 92. The elastic labeling roller 93 and two positioning clamping rollers 83 are arranged in a triangle. When the bottle rotates for labeling, the elastic roller can adapt to the curvature of the bottle and press the label tightly onto the bottle surface. The rotary motor 92 drives the elastic labeling roller 93 to rotate synchronously, avoiding scratches on the label due to friction and improving the aesthetics of the packaging labeling. The label traction mechanism 12 includes a mounting base 125 connected to the conveying mechanism 1. A label peeling plate 121, a label tensioning wheel 126, a guide roller 123, and a label winding roller 122 are fixedly installed on the upper surface of the mounting base 125. A power component 124 for driving the guide roller 123 and the label winding roller 122 to rotate is installed on the bottom surface of the mounting base 125. The guiding mechanism 10 includes two fixing rings fixedly connected to the conveying mechanism 1. Each fixed ring seat 16 has a vertical rod 17 inside, and the top of each vertical rod 17 is connected to a horizontal rod seat 18. Each horizontal rod seat 18 has a guide rod 19 inside, and one end of the two guide rods 19 is fixedly connected to a side guide plate 20. The outer surface of each fixed ring seat 16 and the outer surface of the horizontal rod seat 18 are provided with fastening screws. The label traction mechanism 12's peeling plate 121 and label tensioning wheel 126 ensure smooth traction and precise peeling of the label tape, without label breakage or skewing. The label traction mechanism 12 is existing technology. Its core principle is to change the movement direction of the label paper tape through a peeling plate, also known as a peeling blade or peeler. It utilizes the difference in physical properties between the label material, which is usually paper or film, and the backing paper to separate the label from the backing paper. The side guide plate 20 of the guide mechanism 10 can be adjusted in position through the vertical rod 17 and the horizontal rod seat 18 to guide the conveying direction of the round bottle. If the bottle body deviates from the center line of the conveyor belt 102, it ensures that the bottle body accurately enters the subsequent process.

[0035] The working principle of this utility model is as follows:

[0036] Before use, check whether the positioning clamping roller 83 is flexible, whether the bottle separating elastic roller 115 of the bottle separating star wheel 114 is intact, and whether the label peeling plate 121 and guide roller 123 of the label traction mechanism 12 are clean; confirm that the conveyor belt 102 is undamaged and the receiving frame 5 is placed in place. According to the size of the round cosmetic bottle to be labeled, set the parameters on the intelligent controller 4, such as the spacing of the positioning clamping roller 83 and the alignment of the clamping roller height of the height adjustment mechanism 7 with the middle of the bottle body.

[0037] Next, based on the size of the round cosmetic bottle to be labeled, the servo motor 131 can be started to drive the bidirectional screw 132 to rotate. Under the action of the screw, the transmission screw plate 133 drives the positioning clamping roller 83 to move to the appropriate distance. The positioning clamping roller 83 moves on the guide bar 135 and the circular column 134 to ensure that the clamping roller moves smoothly. Then, the threaded rod 73 is rotated, the support plate 74 is adjusted to drive the positioning mechanism 8 to rise and fall to the set height, and the vertical rod 17 and the horizontal rod seat 18 of the guide mechanism 10 are adjusted so that the side guide plate 20 is aligned with the center line of the conveyor belt 102 to ensure that the bottle body is conveyed without deviation.

[0038] Then, the power component 124 of the label traction mechanism 12 can be activated. The label strip is pulled to the peeling plate 121 via the guide roller 123 and the label tensioning wheel 126. The label is confirmed to be accurately peeled off. The label winding roller 122 normally winds up the bottom paper. Then, the conveyor drive motor 103 and the bottle separation drive motor 112 can be activated. The round bottle to be labeled is placed at the front end of the conveyor belt 102. The bottle separation star wheel 114 rotates. The bottle separation elastic roller 115 separates the conveyed round bottles one by one. The single bottle is orderly conveyed to the labeling position along the conveyor belt 102. After the round bottle is separated and spaced, it enters the positioning clamping roller 83. The drive cylinder 81 drives the transmission box 82 and the positioning clamping roller 83 to move and position the round bottle. The elastic labeling roller 93 is used to position the bottle body. After the clamping roller clamps the bottle, the rotary motor 92 drives the elastic labeling roller 93 to rotate and rotate it. At the same time, the label peeled off by the peeling plate 121 is attached to the bottle body. At the same time, the elastic labeling roller 93 of the labeling mechanism 9 rotates and presses the label to ensure tight adhesion.

[0039] After the round bottle with the label is removed from the positioning, it moves with the conveyor belt 102 and finally falls into the receiving box 5. The side guardrail 6 prevents the bottle from falling. The operator regularly empties the receiving box 5 and checks the labeling quality, such as the label position and flatness. When the bottle type needs to be changed, the corresponding preset parameters are called on the intelligent controller 4, and the equipment automatically adjusts the clamping roller spacing, height and conveying speed without the need for manual disassembly of parts.
