Description

Technical Field

[0001] This invention relates to the field of filling production equipment technology, specifically to a brush device in a labeling machine. Background Technology

[0002] With the rapid development of beverage products, the specifications of labels on beverage packaging are also increasing. Labeling machines typically include a container conveying mechanism, with labeling and brushing stations located on the outer side of this mechanism. The labeling station has a labeling roller, and the brushing station has a brush device. The labeling roller has several through holes evenly distributed on its body, and a negative pressure chamber connected to a negative pressure assembly is located inside the roller. Each through hole is connected to the negative pressure chamber, and under the action of the negative pressure assembly, a negative pressure is created between the negative pressure chamber and the through holes, thus adsorbing the label onto the roller surface. The brush device consists of a brush assembly, with brushes covering its inner side. The container conveying mechanism includes a rotating turntable with several stations spaced circumferentially. Each station has a rotation drive mechanism that drives the container to rotate. The rotation of the turntable sequentially transports the containers to be labeled from each station to the labeling and brushing stations.

[0003] During the labeling process, the turntable revolves, continuously transporting containers to be labeled to the labeling station and the brushing station. At the labeling station, the labeling roller attaches the head of the label to the container. The container then moves away from the labeling station as the turntable revolves, while its own rotation causes the label to gradually wrap around the container. One full rotation of the container ensures the label's tail is firmly attached to the head. The container then revolves to the brushing station, where it continues to revolve and rotate along with the brush device. The container rotates at least one full rotation from the front to the rear of the brush device. The brushes on the brush device smooth and apply pressure to the label on the container, ensuring reliable adhesion from head to tail.

[0004] In the labeling process described above, after one end of the label is attached to the container, the container needs to rotate once for the entire label to be completely wrapped around it. However, during this rotation, the other end of the label has already detached from the labeling roller. Under gravity, the label that is not yet attached to the container tends to sag, resulting in a height difference between the beginning and end of the label after one rotation. This leads to uneven label placement on the container, i.e., severe labeling errors. Furthermore, the brush device is fixed; when the label placement position on the container needs to be changed, the corresponding brush device must be replaced. This is not only time-consuming and labor-intensive but also increases packaging production costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a labeling brush device with a simple and ingenious structure that can ensure that the two ends of the label are flush and improve the packaging quality.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a labeling brush device, comprising: an arc-shaped brush support disposed at the labeling station outside the conveying mechanism of the container to be labeled; a brush assembly disposed on the inner side wall of the brush support; a suction seat disposed at the front end of the brush support; a plurality of suction holes formed on the inner side wall of the suction seat; a plurality of negative pressure channels disposed inside the suction seat; each suction hole communicating with a negative pressure channel; and a negative pressure chamber disposed on the outer side wall of the suction seat. All pressure channels are connected to the negative pressure chamber, which is connected to the vacuum pipe, which is connected to the negative pressure generator. The suction seat is located on the outside of the container conveying mechanism between the labeling station and the brushing station. The front end of the suction seat extends close to the labeling station. Each label is pasted onto the container to be labeled by the labeling roller at the labeling station. The container to be labeled moves away from the labeling station and enters the inside of the suction seat. Labels that are not yet wrapped around the container will be adsorbed onto the inner wall of the suction seat.

[0007] Furthermore, in the aforementioned labeling brush device, the brush support is mounted on a frame, and the connection structure between the brush support and the frame includes: at least two connecting sleeves are fixedly installed on the outer side wall of the brush support, the connecting sleeves are spaced apart along the circumference of the arc-shaped brush support, each connecting sleeve is provided with a connecting post, each connecting sleeve and the corresponding connecting post are detachably fixedly connected by bolts, and a fixing seat with a connecting groove is fixedly installed at the bottom of each connecting post. The frame is provided with several mounting holes for adjusting the installation angle of the brush support, and the fixing seat is fixedly connected to the mounting holes by locking bolts.

[0008] Furthermore, in the aforementioned labeling brush device, the brush assembly includes a brush assembly body section and a brush assembly transition section. The brush assembly transition section is located at one end near the suction seat, and the length of the brush assembly transition section protruding from the inner wall of the brush support gradually increases until it matches the length of the brush assembly body section protruding from the inner wall of the brush support.

[0009] Furthermore, in the aforementioned labeling brush device, the inner wall of the suction seat is smooth.

[0010] Furthermore, in the aforementioned labeling brush device, the negative pressure generator is a vacuum pump, and a flow regulating valve is installed on the vacuum connection pipe.

[0011] Furthermore, in the aforementioned labeling brush device, a brush support connecting section is provided at one end of the brush support near the suction seat. The brush support connecting section protrudes from the brush assembly and extends to the outer wall of the suction seat, and the suction seat is connected to the brush support connecting section.

[0012] Furthermore, in the aforementioned labeling brush device, the front end of the suction seat is a sharp shape that facilitates insertion into the labeling station.

[0013] The advantages of this invention are as follows: This application provides a labeling brush device with the following advantages: 1. An air suction seat is provided at its front end. Labels not yet pasted on the container are attracted by the air suction seat, thus supporting the label and preventing it from falling during the application process, thereby ensuring that both ends of the label are flush. 2. Since the air suction seat is located on the brush support, and the brush support is connected to the connecting column through a connecting sleeve, the height of the entire brush support is adjustable. This can adapt to the application of labels with different labeling height requirements, making it applicable to a wide range of scenarios and reducing packaging production costs. In addition, by changing different mounting holes on the frame, the installation angle and position of the entire brush support can be adjusted to better meet the label application requirements.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a labeling brush device includes: an arc-shaped brush support 2 disposed at a labeling station 20 outside the container conveying mechanism 1; a brush assembly 21 disposed on the inner side wall of the brush support 2; a suction seat 3 disposed at the front end of the brush support 2; a plurality of suction holes 31 opened on the inner side wall of the suction seat 3; a plurality of negative pressure channels 32 disposed inside the suction seat 3; each suction hole 31 communicating with a negative pressure channel 32; a negative pressure chamber 33 disposed on the outer side wall of the suction seat 3; all negative pressure channels 32 communicating with the negative pressure chamber 33; the negative pressure chamber 33 communicating with a vacuum connector 34; and the vacuum connector 34 communicating with a negative pressure generator. In this embodiment, the negative pressure generator is a vacuum pump, and a flow regulating valve 341 is disposed on the vacuum connector 34. The purpose of the flow regulating valve 341 is to adjust the negative pressure adsorption force according to actual needs. The inner wall of the suction seat 3 is smooth, which facilitates the movement of the label on the inner wall of the suction seat 3.

[0019] The suction seat 3 is located outside the container conveying mechanism 1 to be labeled, between the labeling station 30 and the brushing station 20. The front end of the suction seat 3 extends close to the labeling station 30. In this embodiment, the front end 301 of the suction seat 3 is sharp and can be easily inserted close to the labeling station 30.

[0020] Each label is attached to the container 5 to be labeled by the labeling roller 4 at the labeling station 30. After the labeling container 5 moves away from the labeling station 30 and enters the inner side of the suction seat 3, the labels that are not yet wrapped around the container 5 will be adsorbed on the inner wall of the suction seat 3.

[0021] In this embodiment, the brush support 2 is mounted on the frame. The connection structure between the brush support 2 and the frame includes: at least two connecting sleeves 22 are fixedly disposed on the outer side wall of the brush support 2. The connecting sleeves 22 are spaced apart along the circumference of the arc-shaped brush support 2. Each connecting sleeve 22 is provided with a connecting post 23. Each connecting sleeve 22 and the corresponding connecting post 23 are detachably fixedly connected by bolts. The bottom of each connecting post 23 is fixedly provided with a fixing seat 25 with a connecting groove 251. The frame is provided with several mounting holes 26 for adjusting the installation angle of the brush support 2. The fixing seat 25 is fixedly connected to the mounting holes 26 by locking bolts. By selecting different mounting holes 26 and adjusting the connection position of the connecting groove 251, the installation position and installation angle of the brush support 2 can be changed.

[0022] The brush assembly 21 includes a brush assembly body section 211 and a brush assembly transition section 212. The brush assembly transition section 212 is located at one end near the suction seat 3. The length of the brush assembly transition section 212 protruding from the inner wall of the brush support 2 gradually increases until it is consistent with the length of the brush assembly body section 211 protruding from the inner wall of the brush support 2.

[0023] A brush support connecting section 201 is provided at one end of the brush support 2 near the suction seat 3. The brush support connecting section 201 protrudes from the brush assembly 21 and extends to the outer wall of the suction seat 3. The suction seat 3 is connected to the brush support connecting section 201.

[0024] Working principle: A labeling machine typically includes a container conveying mechanism 1. A labeling station 30 and a label brushing station 20 are located on the outer side of the container conveying mechanism 1. A labeling roller 4 is installed at the labeling station 30, and a brush device is installed at the label brushing station 30. During labeling, the label is conveyed by the labeling roller 4, and the container conveying mechanism 1 continuously conveys the containers to be labeled 5 to the labeling station 30. The negative pressure generator operates, forming a negative pressure adsorption surface on the inner wall of the suction seat 3.

[0025] At labeling station 30, labeling roller 4 affixes the head of label 6 to the container 5 to be labeled, which has moved to labeling station 30. Adhesive is applied to the head of label 6. The container 5 to be labeled revolves on the labeling container conveyor 1 while rotating on its own axis. The container 5 with label 6 affixed revolves away from the labeling station and moves towards labeling station 20, while its rotation continuously wraps the label around itself. Since a suction seat 3 is provided between the labeling station and labeling station 20, when the container 5 to be labeled enters the inner side of the suction seat 3, the label 6 between the labeling station and the container 5 that is not yet wrapped around the container 5 is adsorbed onto the negative pressure adsorption surface formed by the inner wall of the suction seat 3. The suction seat 3 adheres to the label 6, providing support and stability, preventing the label from sagging before it is attached to the container. This ensures the label remains at the same height throughout the labeling process, guaranteeing that the beginning and end of the label are flush and significantly improving product packaging quality. Next, the tagged container continues to rotate while revolving, entering the labeling station 20. It then passes through the brush assembly transition section 212 to the brush assembly body section 211. The brush assembly 21 presses down on the label, ensuring reliable adhesion at both ends. The brush assembly transition section 212 facilitates the smooth entry of the container into the labeling station area.

[0026] In this application, the brush support 2 is connected to the connecting post 23 via a connecting sleeve 22. This allows for adjustment of the overall height of the brush support 2 by adjusting the relative position of the connecting sleeve 22 and the connecting post 23, thus accommodating labels with different labeling height requirements. Furthermore, the mounting angle and position of the entire brush support 2 can be adjusted by changing different mounting holes 26 on the frame, thereby better meeting the labeling needs.

[0027] As can be seen from the above, this application provides a labeling brush device, which has the following advantages: 1. An air suction seat 3 is provided at its front end. The label 6, which has not yet been pasted onto the container, is attracted by the air suction seat 3, thereby supporting the label 6 and preventing it from falling during the application process, thus ensuring that the two ends of the label are flush. 2. Since the air suction seat 3 is set on the brush support 2, and the brush support is connected to the connecting post 23 through the connecting sleeve 22, the height of the entire brush support 2 is adjustable. This can adapt to the application of labels with different labeling height requirements, making it applicable to a wide range of scenarios and reducing filling production costs. In addition, by changing different mounting holes 26 on the frame, the installation angle and position of the entire brush support 2 can be adjusted, thereby better meeting the label application requirements.
