[0034] Reference Figures 1-5 A scribing device for easy adjustment of scribing angle includes a scribing machine body 1, a scribing machine 2, and a rotating component 3. The scribing machine 2 is mounted on the scribing machine body 1, and the rotating component 3 passes through the scribing machine body 1 and is rotatably connected to the scribing machine body 1 to control the adjustment angle of the scribing machine body 1.

[0035] Specifically, the marking machine body 1 includes a support plate 11, a bracket 12, and rollers 13. The rollers 13 are mounted on both sides of the support plate 11 and are rotatably connected to the support plate 11, so that the rollers 13 drive the support plate 1 and the bracket 12 to move. The brackets 12 are located on both sides of the rear end of the support plate 11 and are fixedly connected to the support plate 11. The rotating assembly 3 passes through the bracket 12 and is rotatably connected to the bracket 12 in a limited manner.

[0036] Specifically, the marking machine 2 includes a material cylinder 21, a feeding pump 22, a connecting plate 23, a baffle plate 24, and a fixing pin 25. The material cylinder 21 and the feeding pump 22 are both mounted on the support plate 11, and the feeding pump 22 is interconnected with the material cylinder 21 to feed material from the output end of the feeding pump 22 to the output end. The output end of the feeding pump 22 is also connected to a discharge pipe 221, and the end of the discharge pipe 221 is connected to a nozzle 222, so that the nozzle 222 is interconnected with the feeding pump 22. The connecting plate 23 is mounted on the upper end of the nozzle 222 and is sleeved on the discharge pipe 221, and is fixedly connected to the discharge pipe 221. A rotating plate 231 is provided at the lower end of the connecting plate 23, and the rotating plate 231 abuts against both sides of the nozzle 222. The rotating plate 231 has a rotating hole, and the baffle plate 24 is embedded in the rotating hole by the fixing pin 25 to fix the baffle plate 24. A positioning rod 232 is provided at the center of the front side of the connecting plate 23, and the positioning rod 232 is installed opposite to the middle position of the nozzle 222. The baffle plate 24 is rotatably connected to the rotating plate 231 so that the relative adjustment angle of the baffle plates 24 on both sides is fixed by the fixing pin 25. A baffle cavity 241 is provided on one side of the upper end face of the baffle plate 24, and the upper end of the baffle cavity 241 has an opening. At the same time, the baffle cavity 241 is also connected to the inner wall of the nozzle 222 so that when the baffle plate 24 is adjusted to a small opening angle, the sprayed part of the nozzle 222 near the edge of the baffle plate 24 can enter the baffle cavity 241 to prevent the sprayed material from splashing. A rotating groove 242 is also provided on the inner end of the baffle cavity 241. The opening width of the rotating groove 242 matches the rotating plate 231, and the opening depth of the rotating groove 242 is greater than the rotation radius along the nozzle 222. It should be noted that the actual spraying width of the nozzle 222 is between the two opposing baffles 24. The actual spraying width of the nozzle 222 changes accordingly by adjusting the two opposing baffles 24. When the two opposing baffles 24 are rotated to the required spraying width, the fixing pins 25 pass through one side of the baffles 24 respectively and abut against it, so that the baffles 24 are fixed relative to the rotating plate 231.

[0037] Specifically, the rotating assembly 3 includes an operating support rod 31, a rotating shaft 32, a linkage mechanism 33, a limiting rotating part 34, and a rotating wheel 35. The operating support rod 31 is mounted on the upper end of the bracket 12. The operating support rod 31 is rotatably connected to the bracket 12 with a relative limitation, and handles 311 are provided on both sides of the operating support rod 31. A switch 312 is provided at the front end of one of the handles 311, which is activated by the operator pressing the switch 312. The switch 312 is connected to the material pump 22 to control the material pump 22 for material delivery and spraying. The upper end of the rotating shaft 32 is fixedly connected to the operating support rod 31, and the rotating shaft 32 passes through the bracket 12 and is rotatably connected to the bracket 12, so that when the operating support rod 31 rotates, it drives the rotating shaft 32 to rotate with a limited limitation. The lower end of the rotating shaft 32 is fixedly connected to the linkage mechanism 33, and the linkage mechanism 33 is installed at the lower end of the support plate 11. When the rotating shaft 32 rotates, the linkage mechanism 33 rotates along with the rotating shaft 32. The linkage mechanism 33 includes a first linkage plate 331, a first linkage rod 332, a second linkage plate 333, a second linkage rod 334, and a connecting end 335. The first linkage plate 331 is fixedly connected to the lower end of the rotating shaft 32. In this embodiment, two first linkage rods 332 are provided, and the two first linkage rods 332 are respectively hinged to the front ends of the first linkage plate 331, and the first linkage rods 332 are located at the lower end of the support plate 11. The second linkage plate 333 is located at the end of the first linkage rod 332 away from the first linkage plate 331, and the second linkage plate 33 is hinged to the first linkage rod 332. The second linkage plate 333 is sleeved on the limiting rotation part 35, which is located at the lower middle part of the support plate 11. The second linkage plate 333 and the limiting rotation part 35 are rotatably connected in a limiting manner, and the limiting rotation part 35 is located at the end away from the roller 13. In this embodiment, two second linkage rods 334 are provided, and the two second linkage rods 334 are respectively installed on both sides of the lower end of the second linkage plate 333, and the second linkage rods 334 are fixedly connected to the second linkage plate 333. Connecting ends 334 are respectively installed on the lower ends of the second linkage rods 334, and the connecting ends 334 are arranged opposite to each other, so that the rotating wheel 35 is connected to the connecting ends 334. The two sides of the rotating wheel 35 are rotatably connected to the connecting ends 334, so that the rotation is driven by the operating support rod 31 to drive the rotating shaft 32 and the linkage mechanism 33, ultimately causing the rotating wheel 35 to turn. It should be noted that the lower edges of the roller 13 and the rotating wheel 35 are flush with each other to ensure the linkage of the travel trajectory.

[0038] Working Principle: First, the operator manually drives the steering system by operating the support rod. The support rod drives the rigidly connected rotating shaft to rotate, and this rotational force is transmitted to both sides of the first linkage rod via the first linkage plate. Second, the first linkage rod pushes the second linkage plate to move in an arc around the limiting rotating part. Through the connecting end of the second linkage rod, it drives the rotating wheel to deflect at a precise angle. This deflection angle forms a vector linkage relationship with the roller's travel trajectory, thereby changing the direction of the equipment's movement. Finally, the spraying axis of the nozzle forms a fixed angle with the direction of the equipment's movement through the spatial positioning relationship of the mechanical structure. When the rotating wheel turns, the spraying trajectory of the nozzle changes angle accordingly. Throughout the steering process, the multi-stage linkage transmission system of the linkage mechanism converts the rotational motion of the operating end into the linear displacement of the rotating wheel, and the axial constraint of the limiting rotating part ensures steering stability.

[0039] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
