Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and more specifically, to an adaptive rolling mechanism for an eye drop bottle labeling machine. Background Technology

[0002] Currently, bottle packaging is widely used in many industries such as food and medicine. Labels are usually affixed to bottle packaging and the labels are pressed firmly with pressure rollers. The labeling process is usually completed by automated labeling machines. For example, when labeling eye drop bottles, the label needs to be pressed firmly by the roller mechanism on the labeling machine.

[0003] However, existing technologies have some problems: In actual operation, although the rolling mechanism on the existing labeling machine can squeeze the eye drop bottle and make it rotate to attach the label, some rigid rolling mechanisms cannot adapt to eye drop bottles of different diameters, which can easily lead to poor adhesion or deformation of the bottle. Although some rolling mechanisms are equipped with springs, the pressure provided by the traditional spring-pressing rolling mechanism is unidirectional. At the moment of squeezing the bottle body, it is still easy to over-squeeze the bottle body, which makes it difficult to provide good applicability and protection. Therefore, we propose an adaptive rolling mechanism for an eye drop bottle labeling machine. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for an adaptive rolling mechanism for an eye drop bottle labeling machine.

[0005] According to a first aspect of this utility model, an adaptive rolling mechanism for labeling eye drop bottles is provided, comprising a base, a conveyor belt disposed on the base, a drive motor fixedly mounted at the bottom of the base, an output shaft of the drive motor connected to a rotating shaft via a coupling, the top end of the rotating shaft extending above the base and fixedly connected to a polyurethane sleeve, a pressure roller disposed on the base, an electric push rod fixedly mounted on the base, the pressure roller and the electric push rod being connected via an elastic component, the pressure roller being able to push the eye drop bottles on the conveyor belt to the polyurethane sleeve for rolling via the electric push rod and the elastic component.

[0006] Optionally, the elastic component includes a push plate, which is fixedly connected to the telescopic end of the electric push rod. A guide rod is movably inserted into the push plate, and a square plate is fixedly connected to the guide rod. The pressure roller is disposed on the square plate, and a first spring is movably sleeved on the outer surface of the guide rod. The two ends of the first spring are respectively fixedly connected to the push plate and the square plate.

[0007] Optionally, a rotating plate is hinged to the square plate, and the other end of the rotating plate is rotatably connected to the pressure roller shaft.

[0008] Optionally, a vertical plate is fixedly installed on each of the two rotating plates, and a second spring is fixedly connected between the two vertical plates.

[0009] Optionally, a pad is fixedly installed on the surface of the vertical plate, and the two pads are arranged symmetrically.

[0010] Optionally, the top of the polyurethane sleeve is flush with the top of the rotating shaft, and the surface of the polyurethane sleeve is provided with anti-slip texture.

[0011] According to one embodiment of this disclosure, by setting a pressure roller and an elastic component, when the electric push rod is running, the elastic component can drive the pressure roller to move closer to the polyurethane sleeve, thereby pushing the eye drop bottle to the polyurethane sleeve.

[0019] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] like Figures 1-4 As shown, an adaptive rolling mechanism for labeling eye drop bottles includes a base 1, a conveyor belt 2 on the base 1, a drive motor 3 fixedly installed at the bottom of the base 1, a rotating shaft 4 connected to the output shaft of the drive motor 3 via a coupling, the top end of the rotating shaft 4 extending above the base 1 and fixedly connected to a polyurethane sleeve 5, a pressure roller 6 on the base 1, and an electric push rod 7 fixedly installed on the base 1. The pressure roller 6 and the electric push rod 7 are connected by an elastic component. The pressure roller 6 can push the eye drop bottles on the conveyor belt 2 to the polyurethane sleeve 5 for rolling through the electric push rod 7 and the elastic component.

[0024] When the eye drop bottle on conveyor belt 2 is detected at the polyurethane sleeve 5, the electric push rod 7 operates, causing the elastic component to drive the pressure roller 6 to move closer to the polyurethane sleeve 5. This pushes the eye drop bottle to the polyurethane sleeve 5, causing the label paper on the label feeding belt to adhere to the eye drop bottle. The rotation of the polyurethane sleeve 5 causes the eye drop bottle to rotate, so that the polyurethane sleeve 5 and the pressure roller 6 together roll the label paper adhered to the eye drop bottle. Due to the presence of the elastic component, it can adapt to eye drop bottles of different sizes and prevent the eye drop bottle from being excessively squeezed and deformed, thus having good applicability and protection.

[0025] The above-mentioned adaptive rolling mechanism for labeling eye drop bottles includes a push plate 8, which is fixedly connected to the telescopic end of an electric push rod 7. A guide rod 9 is movably inserted into the push plate 8, and a square plate 10 is fixedly connected to the guide rod 9. A pressure roller 6 is set on the square plate 10. A first spring 11 is movably sleeved on the outer surface of the guide rod 9, and the two ends of the first spring 11 are respectively fixedly connected to the push plate 8 and the square plate 10.

[0026] By setting the first spring 11 to the normal state, when the electric push rod 7 runs, it causes the push plate 8 to drive the square plate 10 and the pressure roller 6 to move, pushing the eye drop bottle to the polyurethane sleeve 5. If the diameter of the eye drop bottle is slightly larger, the first spring 11 will be squeezed and deformed, thus adapting to different sizes of eye drop bottles and preventing the eye drop bottle from being excessively squeezed, achieving a preliminary protective effect.

[0027] The above-mentioned adaptive rolling mechanism for labeling eye drop bottles has a rotating plate 12 hinged to a square plate 10, and the other end of the rotating plate 12 is rotatably connected to the pressure roller 6.

[0028] The square plate 10 drives the pressure roller 6 to move through the rotating plate 12. When the square plate 10 drives the pressure roller 6 to squeeze the eye drop bottle, the rotating plate 12 will rotate so that the two pressure rollers 6 move in opposite directions, thereby further preventing the pressure roller 6 from directly squeezing a certain part of the surface of the eye drop bottle, thus dispersing the squeezing force and further preventing the eye drop bottle from being over-squeezed.

[0029] The above-mentioned adaptive rolling mechanism for labeling eye drop bottles has vertical plates 13 fixedly installed on both sides of the rotating plate 12, and a second spring 14 is fixedly connected between the two vertical plates 13.

[0030] By setting the second spring 14 to its normal state, when the pressure rollers 6 squeeze the eye drop bottle and move in opposite directions, the second spring 14 will be stretched. Due to the tension of the second spring 14, the two pressure rollers 6 will remain attached to the surface of the eye drop bottle, thereby maintaining a stable rolling effect on the label paper on the surface of the eye drop bottle. Furthermore, the tension of the second spring 14 will allow the two pressure rollers 6 to return to their original positions after one rolling operation is completed.

[0031] The adaptive rolling mechanism of the above-mentioned eye drop bottle labeling machine has a pad 15 fixedly installed on the surface of the vertical plate 13, and the two pads 15 are arranged symmetrically.

[0032] The pad 15 can be made of rubber so that when the two pressure rollers 6 return to their original position under the tension of the second spring 14, the contact between the two pads 15 can buffer and dampen the tension of the second spring 14, thus preventing the rotating plate 12 from vibrating repeatedly and affecting the subsequent rolling and labeling.

[0033] In the above-mentioned adaptive rolling mechanism for labeling eye drop bottles, the top of the polyurethane sleeve 5 is flush with the top of the rotating shaft 4, and the surface of the polyurethane sleeve 5 is provided with anti-slip texture.

[0034] The anti-slip texture on the surface of the polyurethane sleeve 5 allows for better rotation of the eye drop bottle, thus achieving more stable rolling operation.

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

[0036] The operator starts the drive motor 3, causing the rotating shaft 4 to rotate the polyurethane sleeve 5. When the eye drop bottle on the conveyor belt 2 moves to the polyurethane sleeve 5 and is detected, the main controller on the labeling machine activates the electric push rod 7, causing the push plate 8 to move the square plate 10 and the pressure roller 6, pushing the eye drop bottle to the polyurethane sleeve 5. This causes the label paper on the labeling belt to adhere to the eye drop bottle. The rotation of the polyurethane sleeve 5 causes the eye drop bottle to rotate, so that the polyurethane sleeve 5 and the pressure roller 6 together roll the label paper adhered to the eye drop bottle. If the diameter of the eye drop bottle is slightly larger, the first spring 11 will be compressed and deformed, thus accommodating eye drop bottles of different sizes. This design avoids excessive pressure on the eye drop bottle, achieving initial protection. When the square plate 10 drives the pressure rollers 6 to squeeze the eye drop bottle, the rotating plate 12 rotates, causing the two pressure rollers 6 to move in opposite directions. This further prevents the pressure rollers 6 from directly pressing on a certain part of the eye drop bottle surface, thus dispersing the pressure and further preventing excessive pressure on the eye drop bottle. When the pressure rollers 6 squeeze the eye drop bottle and move in opposite directions, they stretch the second spring 14. Due to the tension of the second spring 14, the two pressure rollers 6 remain attached to the surface of the eye drop bottle, thus maintaining a stable rolling effect on the label paper on the surface of the eye drop bottle, thereby providing good applicability and protection.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
