Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, specifically a vertical positioning device for a labeling machine. Background Technology

[0002] Many products are labeled with barcodes, which are usually applied by labeling machines. Existing labeling machines generally include components such as a motor, transmission mechanism, label feed roller, label peeler, take-up roller, positioning rod, and conveyor belt, as well as a control system for controlling the movement of these components. The label feed roller, label peeler, take-up roller, and positioning rod form the labeling head. Labels are attached to the label backing paper to form a label roll, which is placed on the label feed roller. When the labeling machine starts working, the control circuit sends operating commands to the labeling machine's key components, such as causing the motor to rotate, which in turn drives the transmission mechanism to move, unrolling the label roll and sending it to the label peeler. The label peeler separates the label from the label backing paper, and the label is pasted onto the item being conveyed along the conveyor belt, while the label backing paper is sent to the take-up roller to be rolled up and recycled.

[0003] Existing labeling machines, when labeling bottles, lack an effective restraint and positioning mechanism. The squeezing force generated during the labeling process easily causes the bottles to tip over or tilt. This not only reduces the stability of the labeling operation but also easily leads to the production of defective labels. Therefore, there is a need for a device to assist in vertical positioning during labeling. In view of this, this application aims to provide a vertical positioning device for a labeling machine to solve the above-mentioned defects in the prior art. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] like Figures 1 to 2 As shown in this embodiment, a vertical positioning device for a labeling machine includes: The mounting base 1 has three mounting holes on its top left side; L-shaped support 2 is connected to the top of fixed base 1; The electric push rod 3 has its extended end in an extended state and is fixedly connected to an arc-shaped top block 301. The electric push rod 3 is fixedly installed on the bottom inner wall of the L-shaped support 2. The rectangular support sleeve 4 is in active contact with the top of the arc-shaped top block 301; the electric push rod 3 is provided to drive the arc-shaped top block 301 to move up and down, so as to release the lifting state of the rectangular support sleeve 4 or to carry out the lifting work. The spring tension lowering vertical guide assembly consists of two sets, both of which are fixedly connected between the left inner wall of the L-shaped support 2 and the bottom of the rectangular support 4; the spring tension lowering vertical guide assembly is used to drive the rectangular support 4 to move downward and guide it vertically when the lifting state is released. A horizontally adjustable pressure support positioning component is installed inside the rectangular support sleeve 4. After the fixed seat 1 is installed on the side of the bottle conveyor belt of the labeling machine, the horizontally adjustable pressure support positioning component is used to press and position the bottle conveyed to the labeling position downward when the rectangular support sleeve 4 moves down, so as to keep the bottle in an upright state and prevent the bottle from accidentally tipping over during labeling.

[0018] Furthermore, the L-shaped support 2 is fixedly connected to the top of the fixed base 1 by welding.

[0019] Furthermore, such as Figure 1 and 2 As shown, the spring tension lowering vertical guide assembly includes a support base 5, two vertical guide rods 503, a moving plate 501, and a compression spring 502. Both sets of support bases 5 are fixedly connected to the left inner wall of the L-shaped support 2. The electric push rod 3 is located between the two support bases 5. The moving plate 501 is fixedly connected to the bottom of the corresponding two vertical guide rods 503. The support base 5 is slidably sleeved on the corresponding two vertical guide rods 503. The compression spring 502 is in a compressed state and is fixedly connected between the top of the corresponding moving plate 501 and the bottom of the support base 5. The tops of the four vertical guide rods 503 are all fixedly connected to the bottom of the rectangular support sleeve 4. In this embodiment, the top of the support base 5 has two vertical guide holes that are respectively slidably fitted onto the outer side of the corresponding vertical guide rod 503, which serve to guide the vertical sliding of the vertical guide rod 503. In this embodiment, the support base 5, two vertical guide rods 503, moving plate 501, and compression spring 502 work together. When the rectangular support sleeve 4 is released from the lifting state, the two compression springs 502, which are in a compressed state, drive the two moving plates 501 to move downward. The two moving plates 501 drive the rectangular support sleeve 4 to move downward through the four vertical guide rods 503. When the rectangular support sleeve 4 is lifted, the rectangular support sleeve 4 drives the two moving plates 501 to move upward through the four vertical guide rods 503, and compresses and stores energy in the two compression springs 502. This achieves the effect of automatically driving the rectangular support sleeve 4 to move downward and guiding it vertically when the lifting state is released.

[0020] Furthermore, such as Figure 1 and 2 As shown, the horizontally adjustable pressure support positioning assembly includes a horizontal support plate 401, a rotating shaft, a pressure plate 402, and a knob bolt 403. The horizontal support plate 401 is slidably sleeved in the rectangular support sleeve 4. The rotating shaft is rotatably installed on the bottom right side of the horizontal support plate 401. The pressure plate 402 is fixedly connected to the bottom end of the rotating shaft. A threaded through hole for threaded connection with the knob bolt 403 is opened on the bottom right side of the rectangular support sleeve 4. In this embodiment, a first bearing is fixedly connected to the bottom right side of the horizontal support plate 401. The inner ring of the first bearing is fixedly fitted to the outer side of the rotating shaft, which achieves the effect of rotating the shaft. In this implementation scheme, the horizontal support plate 401, rotating shaft, pressure plate 402, and knob bolt 403 work together to move the horizontal support plate 401 downward when the rectangular support sleeve 4 moves downward. The horizontal support plate 401 drives the pressure plate 402 downward through the rotating shaft to press and position the bottle body, thus achieving downward positioning support to keep the bottle body vertical and prevent accidental tipping of the bottle label during labeling. Rotating the knob bolt 403 in the reverse direction can release the lock on the horizontal support plate 401. After unlocking, the horizontal support plate 401 can be adjusted laterally to drive the pressure plate 402 to move laterally. Rotating the knob bolt 403 in the forward direction can press and lock the horizontal support plate 401. The adjustable lateral position of the pressure plate 402 allows for easy adjustment of the pressure at the top center of different widths, resulting in better applicability.

[0021] It should be noted that the electric push rod 3 can be connected to the control terminal of the labeling machine control system via conventional wires and relays. It is used to control the electric push rod 3 to start in reverse during labeling and to start and reset in the forward direction after labeling is completed.

[0022] This embodiment can press and position the bottle from top to bottom during labeling to keep the bottle upright and prevent the bottle from tipping or tilting due to the squeezing force generated during the labeling process. This improves the stability of the labeling operation, thereby reducing the production of defective labels. In addition, it allows personnel to adjust the pressing position laterally according to the bottle specifications of different batches, so as to press down on the center of the top of bottles of different widths, thus improving applicability.

[0023] The usage method of this embodiment is as follows: When using the vertical positioning device of the labeling machine, the fixing base 1 is installed and fixed on the side of the bottle conveyor belt of the labeling machine. When the bottle is conveyed to the labeling position and stops to be labeled, the electric push rod 3 drives the arc-shaped top block 301 to move downward, releasing the lifting state of the rectangular support sleeve 4. At this time, the two compression springs 502, which are in a compressed state, drive the two moving plates 501 to move downward. The two moving plates 501 drive the rectangular support sleeve 4 to move downward through the four vertical guide rods 503. The rectangular support sleeve 4 drives the horizontal support plate 401 to move downward. The horizontal support plate 401 drives the pressure plate 402 to press and position the bottle downward through the rotating shaft, realizing the downward positioning support work to keep the bottle vertical. To prevent accidental tipping of the bottle during labeling, after labeling, the electric push rod 3 drives the arc-shaped top block 301 to lift the rectangular support sleeve 4 in the forward direction. The rectangular support sleeve 4 then drives the pressure plate 402 to move upward through the horizontal support plate 401 and the rotating shaft to release the pressing and positioning state. The rectangular support sleeve 4 then drives the two moving plates 501 to move upward through the four vertical guide rods 503, and compresses and stores energy in the two compression springs 502, waiting for the downward pressing and positioning work to be carried out again. This achieves the effect of pressing and positioning the bottle from top to bottom when labeling, so as to keep the bottle in an upright state and avoid the squeezing force generated during the labeling process from causing the bottle to tip or tilt, thereby improving the stability of the labeling operation and reducing the production of defective labels. When the knob bolt 403 is rotated in the reverse direction, the locking of the horizontal support plate 401 can be released. After unlocking, the horizontal support plate 401 can be adjusted laterally to drive the pressure plate 402 to move laterally. Rotating the knob bolt 403 in the forward direction will press and lock the horizontal support plate 401. By adjusting the lateral position of the pressure plate 402, it is convenient to press down on the center of the top of bottles of different widths by adjusting the lateral pressing position, thus improving applicability. Example 2

[0024] like Figures 3 to 4As shown, this embodiment differs from Embodiment 1 in that: the L-shaped support 2 is vertically connected to the top of the fixed base 1, the bottom of the L-shaped support 2 contacts the top of the fixed base 1, and a vertical guide lifting adjustment assembly is installed on the top of the fixed base 1. The vertical guide lifting adjustment assembly is used to drive the L-shaped support 2 to rise and fall vertically. The vertical guide lifting adjustment assembly includes six vertical guide posts 6, a T-shaped screw 602, and a lifting seat 601. The six vertical guide posts 6 are fixedly connected to the top of the fixed base 1 in a rectangular shape. The L-shaped support 2 is slidably sleeved on the three vertical guide posts 6 on the right side. The lifting seat 601 is fixedly connected to the left side of the L-shaped support 2 and is slidably sleeved on the three vertical guide posts 6 on the left side. The T-shaped screw 602 is rotatably installed on the top of the fixed base 1, and the lifting seat 601 is threadedly sleeved on the T-shaped screw 602. The top of the lifting seat 601 is provided with a threaded hole for threaded connection with the T-shaped screw 602. In this embodiment, the bottom left side of the L-shaped support 2 is provided with three vertical guide grooves 201 that are respectively slidably fitted to the outer side of the corresponding vertical guide post 6, which serves to guide the vertical sliding of the L-shaped support 2; the top of the fixed seat 1 and the top right side of the vertical guide post 6 in the middle of the left side are both fixedly installed with second bearings, and the inner side of the inner ring of the two second bearings is fixedly connected to the outer side of the T-shaped screw 602, which serves to rotatably install the T-shaped screw 602.

[0025] It should be noted that the vertical guide post 6, T-shaped screw 602, lifting seat 601 and L-shaped support 2 are all made of stainless steel. The T-shaped screw 602 has a high wear-resistant load-bearing specification with an outer thread clearance of 0.1-0.2mm. It utilizes the advantages of stainless steel, such as high hardness, high wear resistance and good maintenance-free effect, to ensure long-term connection and drive support stability.

[0026] This embodiment allows for flexible adjustment of the initial height of the pressure plate 402, thereby enabling convenient and flexible adjustment of the pressing height. This makes it suitable for pressing and positioning bottles of various heights, avoiding the inability to use the bottle when it is too tall, and further improving its applicability.

[0027] The usage method of this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: Through the cooperation of six vertical guide posts 6, a T-shaped screw 602, and a lifting seat 601, rotating the T-shaped screw 602 drives the lifting seat 601 to move upwards or downwards. The lifting seat 601 slides vertically on the three vertical guide posts 6 on the left side, and drives the L-shaped support 2 to slide vertically on the three vertical guide posts 6 on the right side, achieving the effect of driving the L-shaped support 2 to rise vertically or move downwards. By adjusting the height of the L-shaped support 2, the initial height of the rectangular support sleeve 4, the spring-loaded downward vertical guide assembly, and the horizontally adjustable pressure support positioning assembly can be adjusted. This achieves convenient and flexible adjustment of the pressing height, making it suitable for pressing and positioning bottles of various heights, avoiding the inapplicability when the bottle is too high, and further improving applicability.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
