Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating device for label production. Background Technology

[0002] A coating machine for label processing is a device specifically designed to coat various functional coatings onto the surface of label materials. It mainly consists of an unwinding device, a coating device, a drying device, and a rewinding device. For example, the Chinese utility model patent disclosed in announcement number CN217350070U: a production device for on-demand coating of self-adhesive labels, includes a box with an open top, several coating rollers rotatably connected inside the box, pressure rollers rotatably connected to the top of the coating rollers, and pressure rollers fixed to the top of the box on both sides by pressure roller mounting brackets. A material pool is provided at the bottom of the corresponding coating rollers.

[0003] Existing coating machines often lack flexible and efficient positioning and guiding functions when processing label raw materials of different widths. For example, some equipment requires manual and tedious adjustment of positioning components, which consumes a lot of time and effort. Moreover, the accuracy of manual adjustment is difficult to guarantee, which can easily lead to positional deviations in the label during the coating process, thereby affecting the coating quality and increasing the defect rate of the finished label products. Furthermore, although some equipment has added correction mechanisms during the label raw material conveying process, they cannot be effectively combined with the positioning mechanism. As a result, the adjustment process for positioning and correction during label raw material conveying is lengthy, affecting the processing efficiency. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1:

[0026] like Figures 1-5 As shown, the present invention provides a coating device for label production, including a housing 1, a shaft plate 2, and a take-up frame 6. Multiple feeding rollers 3 are movably installed between the housing 1 and the shaft plate 2, and multiple guiding rollers 4 are also movably installed between the housing 1 and the shaft plate 2. A glue coating mechanism 5 is fixedly installed between the housing 1 and the shaft plate 2 away from the feeding rollers 3. Two bearing seats 7 are fixedly installed on one side of the take-up frame 6 relative to the housing 1. A correction shaft 8 is rotatably installed between the two bearing seats 7. A positioning mechanism 9 is also provided above the correction shaft 8 on the two bearing seats 7. The positioning mechanism 9 includes two L-shaped fixing plates 10. The two L-shaped fixing plates 10 are respectively fixedly installed on one side of the corresponding bearing seat 7 by fixing rings 15. A connecting plate 11 is movably connected to the two L-shaped fixing plates 10. Two adjusting plates 12 are movably installed in the connecting plate 11. A positioning ring 13 is movably installed in the adjusting plate 12.

[0027] like Figures 2-5As shown, multiple grooves 14 are provided on the outer side of the correction shaft 8. The grooves 14 allow the inner side of the positioning ring 13 to connect with the correction shaft 8, thereby guiding and positioning the label material passing through the correction shaft 8. The bottom sides of the connecting plate 11 are respectively fixedly installed on the corresponding first sliders 17. The top sides of the connecting plate 11 are respectively fixedly installed on the second carrier plate 21 and the third carrier plate 23. Two second guide rails 25 are also fixedly installed on the connecting plate 11 between the second carrier plate 21 and the third carrier plate 23. Multiple second sliders 26 are slidably installed on the second guide rails 25. A second motor 22 is fixedly installed on one side of the second carrier plate 21. The second motor 22 is electrically connected to an external main controller via a cable. A second adjusting screw 24 is fixedly installed at the output end of the second motor 22. The end of the second adjusting screw 24 away from the second motor 22 is rotatably installed in the third carrier plate 23. One half of the outer surface of the second adjusting screw 24 is provided with a left-hand thread, and the other half of the outer surface is provided with a right-hand thread. The outer surface of the second adjusting screw 24 is provided with both left-hand and right-hand threads. In conjunction with the third carrier plate 23, the displacement of the two adjusting plates 12 can be adjusted simultaneously. An internally threaded sleeve 27 is fixedly installed on the top of each adjusting plate 12, and side connecting plates 28 are fixedly installed on both sides of each adjusting plate 12. The bottom of each side connecting plate 28 is fixedly installed on the corresponding second slider 26. The internally threaded sleeve 27 is threadedly connected to the second adjusting screw 24. An installation hole 29 is provided inside the adjusting plate 12, and multiple balls 30 are rotatably installed within the installation hole 29. The adjusting plate 12 is threadedly connected to the second adjusting screw 24 via the internally threaded sleeve 27. This allows the positioning ring 13 to be horizontally adjusted and installed on the outside of the correction shaft 8. Multiple third sliders 31 are fixedly installed on the inner side of the positioning ring 13, and a rotating groove 32 is opened on the outer side of the positioning ring 13. The positioning ring 13 is rotatably installed in the mounting hole 29, and the rotating groove 32 is rotatably installed on multiple balls 30. The positioning ring 13 can be adjusted according to the width of the label material by following the adjustment plate 12. A photoelectric sensor 33 is also fixedly installed on one side of the adjustment plate 12. The photoelectric sensor 33 can monitor the edge position of the label material in real time. Example 2:

[0028] like Figure 4As shown, two first guide rails 16 are fixedly installed on two L-shaped fixing plates 10, and multiple first sliders 17 are slidably installed on the two first guide rails 16. The arrangement of the first guide rails 16 and the first sliders 17 provides conditions for the installation of the connecting plate 11 and enables the connecting plate 11 to achieve horizontal displacement adjustment. A first carrier plate 18 is fixedly installed on one side of one of the L-shaped fixing plates 10, and a first motor 19 is fixedly installed on one side of the first carrier plate 18. The first motor 19 is electrically connected to an external main controller via a cable. The output end of 9 is also fixedly installed with a first adjusting screw 20. The cooperation between the first motor 19 and the first adjusting screw 20 can provide a power source for the horizontal displacement adjustment of the connecting plate 11. The end of the first adjusting screw 20 away from the first motor 19 is threadedly connected to the third carrier plate 23. After the first adjusting screw 20 is threadedly connected to the third carrier plate 23, the overall reciprocating movement of the connecting plate 11 can be realized, thereby cooperating with the two sets of adjusting plates 12, the positioning ring 13 and the photoelectric sensor 33 to realize the correction processing of the conveyed label raw material.

[0029] It should be noted that this utility model is a coating device for label production. During processing, firstly, the feeding roller 3 releases the label raw material. The raw material is guided by multiple guide rollers 4 and is smoothly transported to the coating mechanism 5 for coating operation. After coating is completed, it continues to be transported to the winding frame 6.

[0030] When positioning needs to be adjusted according to the width of the label material, the second motor 22 is started. The output end of the second motor 22 drives the second adjusting screw 24 to rotate. Since half of the outer surface of the second adjusting screw 24 has a left-hand thread and the other half has a right-hand thread, and the inner threaded sleeve 27 at the top of the adjusting plate 12 is threadedly connected to the second adjusting screw 24, and the side connecting plates 28 on both sides of the adjusting plate 12 are fixed to the second slider 26 on the second guide rail 25, when the second adjusting screw 24 rotates, the two adjusting plates 12 will move synchronously in opposite or the same direction on the second guide rail 25, thereby adjusting the distance between the two sets of adjusting plates 12 and the positioning ring 13. The third slider 31 on the inner side of the positioning ring 13 cooperates with the sliding groove 14 on the outer side of the correction shaft 8 to achieve positioning and guidance of the label material, ensuring the quality of winding. During operation, the photoelectric sensor 33 monitors the edge position of the label material in real time. Once a deviation of the label material is detected, the external main controller receives the signal and controls the first motor 19 to start. It then calculates the rotation angle of the first adjusting screw 20 based on the deviation distance, thereby causing the first motor 19 to drive the first adjusting screw 20 to rotate. The end of the first adjusting screw 20 away from the first motor 19 is threadedly connected to the third carrier plate 23. The bottom sides of the connecting plate 11 are fixed on the first slider 17 of the first guide rail 16. Therefore, when the first adjusting screw 20 rotates, the connecting plate 11 will move horizontally back and forth on the first guide rail 16, thereby synchronously driving the two sets of adjusting plates 12 and positioning ring 13 to adjust their positions synchronously, thereby correcting the deviation of the label material and ensuring the positional accuracy of the label during the conveying and coating process.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
