Description

Technical Field

[0001] This utility model belongs to the field of labeling machine technology, specifically relating to a limiting device for a round bottle labeling machine. Background Technology

[0002] Labeling machines are an indispensable part of modern packaging. Most of them are devices that affix rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. Automatic bottle labeling machines, on the other hand, are devices that label the outside of round bottles. However, current round bottle labeling machines still have some shortcomings: firstly, they are not convenient for limiting and guiding round bottles of different heights to prevent tipping; secondly, they are not convenient for stable labeling; and thirdly, they do not have an adjustable guardrail to limit the round bottle structure.

[0003] In view of this, in order to solve the above problems, this utility model proposes a limiting device that can adjust the guardrail spacing according to different sizes of round bottles, effectively limit the round bottles during labeling to prevent them from tipping over, and ensure their stability during labeling. Utility Model Content

[0004] This utility model provides a limiting device for a round bottle labeling machine, which can adjust the guardrail spacing according to different bottle sizes, effectively limit the round bottle during labeling to prevent tipping, and ensure its stability during labeling. The specific solution is as follows: A limiting device for a round bottle labeling machine includes a labeling machine body. Spacing adjustment components are respectively provided on both sides of the conveyor belt of the labeling machine body. One front end of each spacing adjustment component is located behind the drive roller. A driven roller assembly is provided on the labeling machine body on the opposite side of the drive roller. The driven roller assembly is driven to rotate by a drive component. A displacement component is provided at the lower end of the labeling machine body to allow the driven roller assembly to move towards the drive roller. A round bottle top limiting component is provided on the labeling machine body on one side of the drive roller.

[0005] Furthermore, the round bottle top limiting assembly includes a support plate, a mounting plate, a lifting cylinder, a connector, and a limiting head. The support plate is detachably mounted on the labeling machine body on one side of the active rubber wheel by bolts. The mounting plate is horizontally mounted on the upper part of the support plate and is located directly above the conveyor belt. The lifting cylinder is mounted on the upper surface of the mounting plate, and its output end passes through the mounting plate and is connected to the connector. The limiting head is rotatably mounted on the lower end of the connector.

[0006] Furthermore, a ball bearing is connected to the lower end of the connector, and the limiting head is located at the lower end of the ball bearing.

[0007] Furthermore, the displacement assembly includes a mounting frame, a displacement cylinder, and a displacement plate. The mounting frame is located at the lower end of the labeling machine body, and sliding grooves are provided on both sides of the lower part of the mounting frame. The displacement plate is slidably disposed between the two sliding grooves by sliders provided on both sides. The displacement cylinder is located on one side of the mounting frame, and the output end of the displacement cylinder moves through the mounting frame and is connected to one side of the displacement plate.

[0008] Furthermore, the driven rubber wheel assembly includes two wheel disks spaced apart vertically, with multiple driven rubber wheels equidistantly arranged on the outer sides of the two wheel disks, and a rotating shaft vertically arranged between the middle of the two wheel disks. The lower end of the rotating shaft is rotatably mounted on a displacement plate, and the driving assembly is mounted on the displacement plate.

[0009] Furthermore, the drive assembly includes a drive motor, two synchronous pulleys and a synchronous belt.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] See Figure 1-6 A limiting device for a round bottle labeling machine includes a labeling machine body 1. Spacing adjustment components 2 are respectively provided on both sides of the conveyor belt of the labeling machine body 1. One front end of the spacing adjustment component 2 is located behind the drive rubber wheel 3. A driven rubber wheel group 4 is provided on the labeling machine body 1 on the opposite side of the drive rubber wheel 3. The driven rubber wheel group 4 is driven to rotate by a drive component 5. A displacement component 6 is provided at the lower end of the labeling machine body 1, which allows the driven rubber wheel group 4 to move toward the drive rubber wheel 3. A round bottle top limiting component 7 is provided on the labeling machine body 1 on one side of the drive rubber wheel 3.

[0021] The round bottle top limiting assembly 7 includes a support plate 701, a mounting plate 702, a lifting cylinder 703, a connector 704, and a limiting head 705. The support plate 701 is detachably mounted on the labeling machine body 1 on one side of the drive roller 3 by bolts. The mounting plate 702 is horizontally mounted on the upper part of the support plate 701 and is located directly above the conveyor belt. The lifting cylinder 703 is mounted on the upper surface of the mounting plate 702. The lifting cylinder 703 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. The cylinder is powered externally, and its output end passes through the mounting plate 702 and is connected to the connector 704. The limiting head 705 is rotatably set at the lower end of the connector 704, with the limiting head 705 facing the middle of the conveyor belt. Specifically, when the round bottle is conveyed by the conveyor belt of the labeling machine body 1 to the position directly below the limiting head 705, the lifting cylinder 703 is activated, which drives the connector 704 to move downward, so that the limiting head 705 is pressed against the top of the round bottle to complete the top limiting.

[0022] The lower end of the connector 704 is connected to a ball bearing 706, and the limiting head 705 is located at the lower end of the ball bearing 706. The ball bearing 706 is designed to reduce the resistance of the limiting head 705 when the round bottle is rotated for labeling.

[0023] The displacement assembly 6 includes a mounting frame 601, a displacement cylinder 602, and a displacement plate 603. The mounting frame 601 is located at the lower end of the labeling machine body 1. The lower two sides of the mounting frame 601 are respectively provided with slide grooves 604. The displacement plate 603 is slidably disposed between the two slide grooves 604 by sliders provided on both sides. The displacement cylinder 602 is disposed on one side of the mounting frame 601. The displacement cylinder 602 is powered by an external source. The output end of the displacement cylinder 602 moves through the mounting frame 601 and is connected to one side of the displacement plate 603. Specifically, when in use, controlling the start of the displacement cylinder 602 will cause its output end to push or pull the displacement plate 603 to move along the slide grooves 604.

[0024] The driven rubber wheel assembly 4 includes two wheel disks 401 arranged vertically and vertically. Multiple driven rubber wheels 402 that can rotate are equidistantly arranged on the outer sides of the two wheel disks 401. Two adjacent driven rubber wheels 402 are used to limit the side of the round bottle. A rotating shaft 403 is vertically arranged between the middle of the two wheel disks 401. The lower end of the rotating shaft 403 is rotatably arranged on the displacement plate 603. The drive assembly 5 is arranged on the displacement plate 603.

[0025] The drive assembly 5 includes a drive motor 501, two synchronous pulleys, and a synchronous belt 502. The drive motor 501 is detachably mounted on the lower surface of the displacement plate 603, and its output shaft moves through the displacement plate 603. The drive motor 501 is powered by an external power source. Synchronous pulleys are respectively mounted on the output shaft of the drive motor 501 and the lower part of the rotating shaft 403. The two synchronous pulleys are connected by the synchronous belt 502. Specifically, controlling the start of the drive motor 501 will drive one of the synchronous pulleys to rotate, which will drive the rotating shaft 403 to rotate, and then drive the wheel 401 to rotate.

[0026] The spacing adjustment assembly 2 includes a fixing block 201, a positioning rod 202, an adjusting rod 203, an adjusting sleeve 204, an L-shaped locking rod 205, and a limiting plate 206. Multiple fixing blocks 201 are spaced apart on both sides of the labeling machine. The fixing blocks 201 are detachably mounted on the side of the labeling machine body 1 by bolts. The positioning rod 202 is vertically mounted on the fixing block 201. The adjusting sleeve 204 is fixedly connected to the upper part of the positioning rod 202. The adjusting rod 203 horizontally passes through the adjusting sleeve 204 and the side wall of the labeling machine body 1 and is fixedly connected to the limiting plate 206. The limiting plate 206... The 6-axis is inclined outward at one end away from the active rubber wheel 3. The adjusting sleeve 204 has a threaded hole horizontally opened on it, which is connected to the adjusting rod 203. The outer side of one end of the L-shaped locking rod 205 has an external thread suitable for the threaded hole. Specifically, when the distance between the two limiting plates 206 needs to be adjusted due to the size of the round bottle, the L-shaped locking rod 205 is rotated to loosen the adjusting rod 203, and the limiting plate 206 is pushed or pulled to move. After adjustment, the L-shaped locking rod 205 is rotated so that its end presses against the adjusting rod 203 to fix it. During adjustment, it is necessary to ensure that the two limiting plates 206 are symmetrical.

[0027] The working principle of this utility model: First, determine the bottle body size adjustment spacing adjustment component 2. During adjustment, rotate the L-shaped locking rod 205 to loosen the adjusting rod 203, and push or pull the limiting plate 206 to move. After adjustment, rotate the L-shaped locking rod 205 so that its end presses against the adjusting rod 203 to fix it. Then, adjust the displacement component 6 to make the distance between the two adjacent driven rubber wheels 402 and the driving rubber wheel 3 meet the limit of the round bottle.

[0028] When labeling round bottles, the drive motor 501 is activated to rotate the shaft 403, which in turn rotates the wheel 401. Then, as the round bottle is conveyed by the labeling machine body 1 to one side of the driven roller 402, and is carried by the conveyor belt between two adjacent driven rollers 402, the lifting cylinder 703 is activated when the bottle is aligned with the driving roller 3. This activates the connecting piece 704, causing it to move downwards, thus pressing the limiting head 705 against the top of the bottle. Simultaneously, the drive motor 501 stops operating. The active rubber roller 3 drives the round bottle to complete the labeling. After the labeling is completed, the drive motor 501 and the lifting cylinder 703 start simultaneously. The lifting cylinder 703 moves the limiting head 705 away from the top of the round bottle, and the drive motor 501 drives the driven rubber roller 402 to rotate so that the labeled round bottle continues to move forward under the conveyor belt. This process is repeated. The tight cooperation between the round bottle top limiting component 7 and the driven rubber roller group 4 can effectively ensure the limiting and stability of the round bottle during the labeling process, ensuring that the labeling can be carried out smoothly.
