Description

Technical Field

[0001] This utility model relates to the field of label processing technology, and more specifically, to a label coating machine. Background Technology

[0002] A label is an additional piece of paper or tag used to identify things. Nowadays, labels are used to mark product targets and categories or contents. They are keywords that define the target, making it easier for oneself and others to find and locate the target. When producing labels, a coating machine is used to coat the raw materials for label making, so that a layer of glue is applied to the surface of the raw materials to facilitate subsequent processing.

[0003] However, most traditional coating machines do not have a mechanism to guide the raw materials for the labels, which means that the raw materials cannot be kept taut during the coating process, resulting in uneven coating on the labels.

[0004] Furthermore, in the process of using traditional coating machines, most of them only use coating rollers to coat the raw materials. This processing method makes it difficult to evenly coat the adhesive on the surface of the raw materials, which will affect the subsequent coating quality. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a label coating machine with the following advantages:

[0018] 1. By setting up a tension roller, an electric push rod, and a sliding block, the user can guide the label raw material into the housing from the middle position of the two feeding rollers, then pass it through the lower end of the tension roller, and then exit it through the two guide rollers to achieve the guiding effect, which facilitates the subsequent coating process. In addition, the height of the tension roller can be adjusted by controlling the electric push rod to keep the label raw material in a taut state and prevent uneven coating.

[0019] 2. By setting up a storage bin, coating roller, recycling box and inclined scraper, the user can turn the handwheel to drive the threaded rod to move the inclined scraper upward so that it contacts the lower surface of the label material, thereby making it easier to scrape the glue at the bottom of the label material into a uniform state, thereby increasing the coating quality of the label and making it convenient to use.

[0030] Please see Figure 1-5 A label coating machine includes a housing 1, with material inlets 2 on both sides of the housing 1. Feeding rollers 3 are rotatably mounted on the inner wall of the material inlets 2 on both the upper and lower sides. Connecting plates 4 are fixedly mounted on the upper part of the outer wall of the housing 1. Two sets of connecting plates 4 are arranged symmetrically. Guide rollers 5 are rotatably mounted on the bottom of the connecting plates 4. A vertical plate 6 is fixedly mounted on one side of the inner wall of the housing 1. Sliding holes 7 are opened on both the vertical plate 6 and the housing 1. Sliding blocks 8 are slidably mounted inside the sliding holes 7. A tensioning roller 9 is rotatably mounted at the middle position of the two sliding blocks 8. An electric push rod 10 is fixedly mounted on the upper end of the vertical plate 6. The output end of the electric push rod 10 is fixedly connected to the sliding block 8. A storage box 11 is located in the middle of the inner wall of the housing 1. A coating roller 12 is rotatably mounted on the upper end of the storage box 11. A motor 23 is mounted on one end of the coating roller 12 on the outer wall of the storage box 11.

[0031] In this embodiment, a recycling box 13 is fixedly provided on the upper end face of the storage box 11 and on one side. One side of the recycling box 13 is connected to the interior of the storage box 11. A threaded rod 14 is movably provided at the bottom and middle position of the recycling box 13. The threaded rod 14 is threadedly connected to the recycling box 13. The upper end of the threaded rod 14 passes through the recycling box 13 and is provided with an inclined scraper 15 that rotates. The lower end is fixedly provided with a handwheel 16. An inclined slope is provided at the connection position between the recycling box 13 and the storage box 11.

[0032] More specifically, the user can guide the label raw material into the housing 1 from the middle position of the two feeding rollers 3, then pass it through the lower end of the tension roller 9, and exit it through the two guide rollers 5 to achieve the guiding effect, which facilitates the subsequent coating. The height of the tension roller 9 can also be adjusted by controlling the electric push rod 10 to keep the label raw material in a taut state and prevent uneven coating. During coating, the motor 23 can be controlled to rotate the coating roller 12 so that it applies the glue inside the storage box 11 to the bottom of the raw material. The handwheel 16 can also be turned to move the threaded rod 14 to drive the inclined scraper 15 upward so that it contacts the lower surface of the label raw material, thereby facilitating the scraping of the glue at the bottom of the label raw material to a uniform state and improving the coating quality of the label.

[0033] Please see Figures 1-3As an embodiment for limiting the label raw material at the upper end of the guide roller 5: a sliding rod 17 is slidably provided on the upper end surface of the housing 1 and on both sides. A lifting frame 18 is fixedly provided at the bottom of the sliding rod 17. A pressure roller 19 is rotatably provided inside the lifting frame 18. A moving block 20 is fixedly provided at the upper end of the two sliding rods 17. An adjusting rod 21 is movably provided at the middle position of the moving block 20. The adjusting rod 21 is threadedly installed with the moving block 20. The bottom of the adjusting rod 21 is rotatably installed with the housing 1, and a rotating disk 22 is fixedly provided at the upper end.

[0034] Specifically, the user can rotate the rotating disk 22 to make the adjusting rod 21 drive the moving block 20 to move downward. At this time, the moving block 20 will drive the sliding rod 17 and the pressure roller 19 to move downward so that they come into contact with the label raw material at the upper end of the guide roller 5, so as to make the guiding effect of the device better.

[0035] Please refer to Figure 2 and Figure 4 As a further embodiment for drying the glue application area: a drying component is provided on one side of the recycling box 13, and an observation window 24 is provided on the outer wall of the storage box 11.

[0036] Specifically, the drying component can quickly dry the glue at the bottom of the raw materials, thereby increasing the efficiency of the device.

[0037] In summary, when using the overall equipment: the user can guide the label raw material into the housing 1 from the middle position of the two feeding rollers 3, then pass it through the lower end of the tension roller 9, and exit it through the two guide rollers 5. Then, by rotating the rotating disk 22, the adjusting rod 21 can be moved downwards to drive the moving block 20. At this time, the moving block 20 will drive the sliding rod 17 and the pressure roller 19 downwards, so that they contact the label raw material at the upper end of the guide roller 5, thereby improving the material guiding effect of the device and facilitating subsequent coating. The height of the tension roller 9 can also be adjusted by controlling the electric push rod 10. The coating roller 12 is rotated slowly by motor 23 during coating to keep the label material taut and prevent uneven coating. The roller applies the adhesive from storage bin 11 to the bottom of the material. The handwheel 16 can be turned to move the threaded rod 14 to the inclined scraper 15 upwards so that it contacts the lower surface of the label material, thus scraping the adhesive at the bottom of the material evenly and improving the coating quality. Excess adhesive scraped off will enter the storage bin 11 through the inclined scraper 15 and the inclined slope for later use.
