Description

Technical Field

[0001] This utility model belongs to the technical field of label application, and in particular relates to an auxiliary labeling device for a labeling machine. Background Technology

[0002] A flat labeling machine is a device that automatically applies labels to the outer surface of products. Currently, it mainly uses self-adhesive labels, which consist of a self-adhesive label and a label backing film. Labeling machines are primarily used in the food, daily chemical, pharmaceutical, and other light industrial industries, and can automatically label products of various shapes.

[0003] However, in some flat labeling machines, the label receiving mechanism is the one that rotates while the label feeding mechanism is passively rotated. This results in the label paper being subjected to great force at the label blade during the labeling process, making the label paper prone to breakage and also causing the label paper to shift during the labeling process. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary labeling device for labeling machines to solve the problems of easy breakage and easy deviation of current label paper.

[0005] To address the aforementioned problems, this utility model provides an auxiliary labeling device for a labeling machine, comprising an auxiliary labeling component and a fixed back plate.

[0006] The auxiliary labeling assembly includes an auxiliary labeling drive roller, an auxiliary labeling feed driven roller, and an auxiliary labeling collect driven roller. One end of the auxiliary labeling drive roller is rotatably connected to the fixed back plate. The side of the fixed back plate rotatably connected to the auxiliary labeling drive roller is the front side of the back plate, and the side opposite the front side is the back side. An drive roller shaft is also fixedly installed at the end of the auxiliary labeling drive roller rotatably connected to the fixed back plate. The drive roller shaft extends from the front side of the back plate through the fixed back plate to the back side of the back plate. A first drive roller pulley and a second drive roller pulley are also fixedly installed on one side of the back side of the back plate. The first drive roller pulley is closer to the back side of the back plate than the second drive roller pulley. The auxiliary labeling collect driven roller is above the auxiliary labeling drive roller, and the auxiliary labeling feed driven roller is to the right of the auxiliary labeling drive roller.

[0007] Both the auxiliary labeling feeding roller and the auxiliary labeling receiving roller are rotatably connected to the front of the back plate, and are located at a position slightly below the center of the front of the back plate.

[0008] A traction motor is provided on the upper right side of the front of the back plate. The housing of the traction motor is fixedly connected to the front of the back plate. The shaft of the traction motor passes through the fixed back plate. A motor pulley is provided on the reverse side of the back plate for the shaft of the traction motor.

[0009] A film recycling roller is provided on the lower left side of the front of the back plate. The film recycling roller is rotatably connected to the front of the back plate. The film recycling roller is also provided with a film recycling shaft. The film recycling shaft passes through the fixed back plate from the front of the back plate to the back of the back plate. A film recycling wheel is also fixedly connected to the film recycling shaft on one side of the fixed back plate.

[0010] An active belt is wound around the motor pulley and the first pulley of the active roller.

[0011] A driven belt is wound around the second pulley of the active roller and the film recycling wheel.

[0012] A label feeding arm is fixedly connected to the right side of the back plate. A label feeding roller is rotatably connected to the end of the label feeding arm away from the fixed back plate. Two label feeding trays are provided on the label feeding roller. The two label feeding trays are parallel and perpendicular to the label feeding roller. One label feeding tray is close to the label feeding arm, and the other label feeding tray is away from the label feeding arm. The space between the two label feeding trays is used to accommodate unused labels.

[0013] A label separation assembly is fixedly connected to the front of the back panel. The label separation assembly includes a label separation fixing plate and a label cutter. The separation fixing plate is fixedly connected to the front of the back panel, and the label cutter is fixedly connected to the label separation fixing plate.

[0014] Furthermore, the auxiliary labeling component is provided with a component cover plate on the side away from the front of the back plate. The auxiliary labeling drive roller, the auxiliary labeling feeding driven roller, and the auxiliary labeling receiving driven roller are rotatably connected to the component cover plate. The component cover plate is L-shaped. The auxiliary labeling component also includes a component fixing column. The component cover plate is connected to the front of the back plate. The component fixing column is used to support the component cover plate.

[0015] A component rotating column is also provided on the lower right side of the auxiliary labeling and label feeding driven roller. The component rotating column is located between the front side of the back plate and the component cover plate. The component rotating column is rotatably connected to the front side of the back plate and the component cover plate. The component rotating column is used to support the component cover plate and support the label film.

[0016] Furthermore, a back cover is detachably provided on the reverse side of the back plate, the back cover being used to cover the first pulley of the drive roller, the second pulley of the drive roller, the motor pulley, the drive belt, and the driven belt.

[0017] Furthermore, a second rotating arm is also provided on the label feeding arm. The second rotating arm is fixedly connected to the label feeding arm. A second rotating roller is rotatably connected to one end of the second rotating arm away from the label feeding arm. The second rotating roller is located above the label feeding tray.

[0023] The beneficial effects of the auxiliary labeling device for a labeling machine provided by this utility model are as follows: Due to the inclusion of an auxiliary labeling component, a fixed back plate, and a traction motor, the traction motor drives the active roller shaft via a drive belt. The auxiliary labeling active roller, in turn, drives the auxiliary labeling receiving driven roller and the auxiliary labeling feeding driven roller. The second pulley of the active roller shaft drives the film recovery roller to rotate via a driven belt. This ensures that during the labeling process, the auxiliary labeling active roller, the auxiliary labeling receiving driven roller, the auxiliary labeling feeding driven roller, and the film recovery roller can all rotate synchronously, preventing label paper misalignment. Furthermore, since both label feeding and receiving apply force synchronously, the force acting on the label blade edge is reduced, lowering the risk of label paper breakage.

[0029] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 5 The present invention provides a more detailed description of an auxiliary labeling device for a labeling machine.

[0030] like Figures 1 to 5 As shown in the figure, an auxiliary labeling device for a labeling machine according to an embodiment of the present invention includes an auxiliary labeling component and a fixed back plate 200.

[0031] In this invention, the auxiliary labeling assembly includes an auxiliary labeling drive roller 100, an auxiliary labeling feeding driven roller 110, and an auxiliary labeling receiving driven roller 120. One end of the auxiliary labeling drive roller 100 is rotatably connected to a fixed back plate 200, and the side of the fixed back plate 200 rotatably connected to the auxiliary labeling drive roller 100 is the front side 210 of the back plate, while the side opposite to the front side 210 is the back side 220 of the back plate. A drive roller shaft is also fixedly mounted on the end of the auxiliary labeling drive roller 100 rotatably connected to the fixed back plate 200. This drive roller shaft passes through the fixed back plate 200 from the front side 210 and extends to the back side 220 of the back plate.

[0032] Understandably, the active roller shaft is also fixedly provided with an active roller first pulley 101 and an active roller second pulley 102 on one side of the back plate reverse side 220, wherein the active roller first pulley 101 is closer to the back plate reverse side 220 than the active roller second pulley 102.

[0033] Regarding the arrangement of the auxiliary labeling components, viewed from the front of the back panel 210, the auxiliary labeling receiving roller 120 is above the auxiliary labeling driving roller 100, and the auxiliary labeling feeding roller 110 is to the right of the auxiliary labeling driving roller 100. Both the auxiliary labeling feeding roller 110 and the auxiliary labeling receiving roller 120 are rotatably connected to the front of the back panel 210.

[0034] When not labeling, the auxiliary labeling drive roller 100 is in contact with the auxiliary labeling feed roller 110 and the auxiliary labeling take-up roller 120. The auxiliary labeling drive roller 100 can rotate these rollers through friction. During labeling, unused labeling paper is held between the auxiliary labeling drive roller 100 and the auxiliary labeling feed roller 110. At this time, the auxiliary labeling drive roller 100 propels the label paper forward through friction, indirectly driving the auxiliary labeling feed roller 110 to rotate through the label paper. Used labeling backing film is held between the auxiliary labeling drive roller (100) and the auxiliary labeling take-up roller 120. The auxiliary labeling drive roller 100 retracts the label backing film through friction, indirectly driving the auxiliary labeling take-up roller 120 to rotate through the label backing film. This allows for simultaneous receipt and delivery of bids.

[0035] On the entire front side of the back panel 210, the auxiliary labeling drive roller 100, the auxiliary labeling feeding drive roller 110, and the auxiliary labeling receiving drive roller 120 are rotatably connected to the lower center of the front side of the back panel 210; this positional design allows the label separation component to be as close as possible when recycling the label backing film.

[0036] In this utility model, a traction motor 300 is also provided on the upper right side of the front side 210 of the back plate. The housing of the traction motor 300 is fixedly connected to the front side 210 of the back plate, and the shaft of the traction motor 300 passes through the fixed back plate 200. A motor pulley 310 is provided on one side of the back side 220 of the back plate.

[0037] A film recycling roller 400 is provided on the lower left side of the front side 210 of the back plate. The film recycling roller 400 is rotatably connected to the front side 210 of the back plate. The film recycling roller 400 is also provided with a film recycling shaft. The film recycling shaft passes through the fixed back plate 200 from the front side 210 of the back plate to the back side 220 of the back plate. A film recycling wheel 410 is also fixedly connected to the film recycling shaft on one side of the fixed back plate 200.

[0038] It should be noted that a drive belt 320 is wound around the motor pulley 310 and the first drive roller pulley 101. A driven belt 330 is wound around the second drive roller pulley 102 and the film recycling roller 410. The rotation of the traction motor 300 drives the first drive roller pulley 101 to rotate via the drive belt 320. The first drive roller pulley 101 is fixed to the drive roller shaft, and the second drive roller pulley 102 is also fixed to the drive roller shaft. Therefore, the rotation of the first drive roller pulley 101 drives the rotation of the drive roller shaft, and the rotation of the drive roller shaft causes the second drive roller pulley 102 to rotate synchronously. The rotation of the second drive roller pulley 102 drives the film recycling roller 410 to rotate via the driven belt 330, thus realizing the synchronous rotation of the auxiliary labeling drive roller 100 and the film recycling roller 400.

[0039] A label feeding arm 500 is fixedly connected to the right side of the back plate 220. A label feeding roller 510 is rotatably connected to the end of the label feeding arm 500 away from the fixed back plate 200. The label feeding roller 510 is provided with two label feeding trays 511. The two label feeding trays 511 are parallel and perpendicular to the label feeding roller 510. One label feeding tray 511 is close to the label feeding arm 500, and the other label feeding tray 511 is away from the label feeding arm 500. The space between the two label feeding trays 511 is used to hold unused label paper, which is wrapped around the label feeding roller 510. The two label feeding trays 511 can limit the label paper on the label feeding roller 510 to prevent the label paper from wrapping outside the label feeding roller 510. At the same time, the label feeding trays 511 can also limit the label paper pulled out for labeling to prevent the pulled-out label paper from deviating and affecting the subsequent pasting work.

[0040] Understandably, a component cover plate 130 is also provided on the side of the auxiliary labeling assembly away from the front side 210 of the back panel. The auxiliary labeling drive roller 100, the auxiliary labeling feed driven roller 110, and the auxiliary labeling take-up driven roller 120 are rotatably connected to the component cover plate 130. The component cover plate 130 is L-shaped. The auxiliary labeling assembly also includes a component fixing post. The component cover plate 130 is connected to the front side 210 of the back panel, and the component fixing post is used to support the component cover plate 130.

[0041] A component rotating column is also provided on the lower right side of the auxiliary labeling and feeding driven roller 110. This rotating column is positioned between the front side of the back plate 210 and the component cover plate 130, and is rotatably connected to both. The rotating column supports the component cover plate 130 and the label film. This design not only further improves the stability of the auxiliary labeling component but also provides support for the used label backing film, facilitating subsequent recycling and preventing unnecessary contact between the label backing film and other components, thus avoiding disruption to the recycling process.

[0042] A back cover 230 is detachably provided on the reverse side 220 of the back plate. The back cover 230 is used to cover the first pulley 101 of the drive roller, the second pulley 102 of the drive roller, the motor pulley 310, the drive belt 320, and the driven belt 330. The back cover 230 can protect the components it covers, reducing external contamination of these components. It can also protect operators from being injured by these components, as these components are in operation during use.

[0043] In this invention, a second rotating arm 620 is also provided on the label feeding arm 500. The second rotating arm 620 is fixedly connected to the label feeding arm 500. A second rotating roller 621 is rotatably connected to the end of the second rotating arm 620 away from the label feeding arm 500. The second rotating roller 621 is located above the label feeding tray 511. The second rotating arm 620 is positioned between the label feeding roller 510 and the fixed back plate 200. A third rotating roller 630 is provided on the upper left side of the back plate front face 210 and is rotatably connected to the back plate front face 210. A fourth rotating roller 640 is provided on the upper right side of the back plate front face 210 and is rotatably connected to the back plate front face 210. A fifth rotating roller 650 is provided below the fourth rotating roller 640 and is rotatably connected to the back plate front face 210. A first rotating roller 610 is provided below the third rotating roller 630 and is rotatably connected to the back plate front face 210.

[0044] Understandably, a label separation assembly is fixedly connected to the front side 210 of the back panel. The label separation assembly includes a label separation fixing plate 710 and a label knife 720. The separation fixing plate is fixedly connected to the front side 210 of the back panel, and the label knife 720 is fixedly installed on the side of the label separation fixing plate 710 that is close to the fifth rotating roller 650 and away from the auxiliary labeling assembly.

[0045] During use, unused labels are pulled out from the label feeding roller 510, and after being reversed by the first rotating roller 610, the labels pass through the second rotating roller 621. After being reversed by the second rotating roller 621, they pass through the third rotating roller 630. Subsequently, after being reversed by the fourth rotating roller 640 and the fifth rotating roller 650, the labels enter the first pulley 101 of the drive roller. The labels pass between the first pulley 101 of the drive roller and the auxiliary labeling drive roller 100. After exiting the first pulley 101 of the drive roller, the labels enter the label separation assembly. After being separated by the label knife 720, the labels are affixed to the product. The label backing film enters the auxiliary labeling drive roller 100 from below the label separation assembly, and passes between the auxiliary labeling drive roller 100 and the auxiliary labeling collection drive roller 120. After exiting the auxiliary labeling collection drive roller 120, the label backing film enters the film recycling roller 400. Throughout the process, the motor drives the auxiliary labeling active roller 100 and the film recycling roller 400 to operate synchronously, which makes the labeling process highly synchronized. Moreover, the label base film is subjected to force on both the label feeding and label receiving sides, making the label less likely to break at the label blade 720 and also preventing the label paper from deviating.

[0046] 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 scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
