Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a coating machine edge cutting mechanism. Background Technology

[0002] The working principle of a fully automatic coating machine is to apply a coating solution to a substrate in a specific manner, and then cure the coated film through processes such as drying and cooling, thereby forming a product with specific functions. Currently, there are coating machines that can coat both sides simultaneously, that is, coat the front and back sides of the substrate with the coating solution at the same time, further improving production efficiency.

[0003] During the coating process, due to the flow and curing of the coating on the substrate, excess and irregular coatings may form at the edges. These parts not only affect the appearance of the product, but may also affect its performance. Therefore, edge trimming is required. Existing automatic coating machines use rotating cutting wheels on their frames to trim the two sides of the finished product. One end of the generated waste material passes through the discharge pipe. A fan is installed at the installation end of the discharge pipe. The fan blows the waste material to the discharge end of the discharge pipe and discharges it.

[0004] The aforementioned automatic coating machine frame typically has only two sets of cutting rollers, arranged left and right, to perform edge trimming on both sides of the finished product. During prolonged use, the cutting rollers gradually wear down due to friction with the material. This wear not only affects the precision and quality of the edge trimming but may also lead to problems such as burrs and unevenness during the trimming process. These issues are often discovered by operators during machine operation. To avoid a reduction in edge trimming quality, operators need to stop the entire automatic coating machine before replacing the damaged cutting rollers, which severely impacts overall production efficiency. Therefore, this application provides an edge trimming mechanism for a coating machine to meet this requirement. Utility Model Content

[0005] The purpose of this application is to provide a cutting mechanism for a coating machine, which solves the technical problem in the prior art that requires the entire automatic coating machine to be stopped before the damaged cutting wheel can be replaced, resulting in a decrease in overall production efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a coating machine edge cutting mechanism, including a mounting plate installed on the coating machine frame, a drive cylinder mounted on the mounting plate, the output end of the drive cylinder being fixedly connected to an L-shaped rod through a mounting bracket, a hollow disc being rotatably provided at the lower end of the L-shaped rod, and a drive gear ring being provided on the outer wall of the hollow disc;

[0009] A drive motor is installed on the outer wall of the hollow disk, and the output shaft of the drive motor is located in the inner cavity of the hollow disk and is meshed with the transmission gear ring through a gear.

[0011] As a preferred embodiment of this invention, an energy-saving unit is also included to reduce the number of cutting wheels that perform non-cutting rotational motion when the drive motor is working normally.

[0012] As a preferred embodiment of this invention, the energy-saving unit includes a slider rotatably mounted on a rotating shaft and three sets of rectangular openings adapted to the rotating shaft and formed on the circular plate.

[0013] The rotating shaft passes through the corresponding rectangular opening, and the two ends of the slider are slidably disposed in the grooves provided on the inner wall of the rectangular opening;

[0014] Initially, only the bottommost cutting wheel is driven by the drive motor to rotate.

[0015] In a preferred embodiment of this invention, the slider is rotatably mounted on the rotating shaft via a bearing.

[0026] 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.

[0027] Example: Reference Figure 1-4 The edge-cutting mechanism of the coating machine shown includes a mounting plate 2 installed on the coating machine frame 1. A drive cylinder 3 is installed on the mounting plate 2. The output end of the drive cylinder 3 is fixedly connected to an L-shaped rod 5 through a mounting bracket 6. A hollow disc 7 is rotatably provided at the lower end of the L-shaped rod 5. A drive toothed ring 8 is provided on the outer wall of the hollow disc 7.

[0028] A rotary motor 4 is mounted on the upper end of the L-shaped rod 5, and the rotary motor 4 is meshed with the drive gear ring 8 through a gear set on the output shaft.

[0029] A circular plate 11 is fixed on the front end of the hollow disc 7, and three sets of rotating shafts 14 are coaxially arranged on the circular plate 11 and arranged around its circumference. Each set of rotating shafts 14 is equipped with a cutting wheel 9 at the end located on the outer side of the hollow disc 7. Each rotating shaft 14 is equipped with a transmission gear 15 at the end located in the inner cavity of the hollow disc 7. A transmission gear ring 17 adapted to the transmission gear 15 is rotatably arranged in the inner cavity of the hollow disc 7.

[0030] A drive motor 10 is installed on the outer wall of the hollow disc 7. The output shaft of the drive motor 10 is located in the inner cavity of the hollow disc 7 and is connected to the transmission gear ring 17 through gears.

[0031] The drive cylinder 3, rotary motor 4, and drive motor 10 are all electrically connected to the PLC controller.

[0032] During operation, the drive motor 10 drives the transmission gear ring 17 to rotate, and the rotation of the transmission gear ring 17 simultaneously drives the three rotating shafts 14 to rotate (because the transmission gear ring 17 meshes with the three transmission gears 15). Only the bottom set of cutting wheels 9 performs the edge cutting operation on the substrate. When it is necessary to replace a damaged cutting wheel 9, the operator can control the PLC controller to make the rotary motor 4 drive the hollow disk 7 to rotate, thereby driving the three sets of cutting wheels 9 to rotate. When the nearest cutting wheel 9 moves to the damaged cutting wheel 9, it stops rotating, completing the switching of the cuttable wheel 9 (the switching process is as follows). Figure 5 As shown in the figure, no downtime is required for replacement, thus improving overall work efficiency.

[0033] It should be noted that during the switching process of the cutting rollers, before the lower end of the damaged cutting roller 9 moves above the substrate, the lower end of the switching cutting roller 9 is located below the lower end of the substrate, which is conducive to forming a complete and uninterrupted cutting operation on the substrate.

[0034] As a preferred embodiment of this invention, an energy-saving unit is also included to reduce the number of cutting wheels 9 that perform non-cutting rotational motion when the drive motor 10 is working normally.

[0035] The purpose is to reduce the load on the drive motor 10 and save energy.

[0036] As a preferred embodiment of this example, Figure 3 and Figure 4 As shown, the energy-saving unit includes a slider 16 rotatably mounted on a rotating shaft 14 and three sets of rectangular openings 12 adapted to the rotating shaft 14 and opened on a circular plate 11.

[0037] The rotating shaft 14 passes through the corresponding rectangular opening 12, and the two ends of the corresponding slider 16 are slidably disposed in the groove 13 provided on the inner wall of the rectangular opening 12.

[0038] Initially, only the bottommost cutting wheel 9 is driven by the drive motor 10 to rotate.

[0039] With this structure, at the beginning, the drive motor 10 can only drive the bottom cutter 9 to rotate, while the two upper cutter 9 will move away from the transmission gear 17 due to their own gravity, thus causing the transmission gear 15 to separate from the transmission gear ring 17. Ultimately, the two upper cutter 9 cannot rotate, thereby reducing the load on the drive motor 10 and saving energy.

[0040] When a damaged cutting wheel 9 needs to be replaced, for example, when the hollow disc 7 is being replaced clockwise, during the rotation, adjacent cutting wheels 9 will swap positions, and during this rotational switching process (see reference...). Figure 5 During rotation, the cutting wheel 9 located to the right of the damaged cutting wheel 9 moves outward under its own gravity and completes the meshing of the transmission gear 15 and the transmission gear ring 17 before contacting the substrate. After the meshing is completed, both cutting wheels 9 below rotate. After the replacement between the two cutting wheels 9 is completed, the transmission gear 15 and the transmission gear ring 17 on the damaged cutting wheel 9 separate and stop rotating. Only the bottommost cutting wheel 9, after being switched, rotates alone to perform edge trimming on the substrate.

[0041] As a preferred embodiment of this example, Figure 4 As shown, the slider 16 is rotatably mounted on the rotating shaft 14 via a bearing.

[0042] The rotational friction between the rotating shaft 14 and the slider 16 can be reduced by using bearings.

[0043] It should be noted that universal ball bearings can be installed on the end face of slider 16 to reduce the friction between it and slide groove 13.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
