DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-5As shown, an embodiment of the present invention proposes a coating machine tool holder, including a mounting plate 1, a movable platform 2 and a lifting assembly. A mounting groove is provided on the side wall of the movable platform 2, and one end of the mounting plate 1 is slidably arranged in the mounting groove. A knife disc 3 is rotatably provided at the end of the mounting plate 1 away from the movable platform 2, and a driving assembly for driving the knife disc 3 to rotate is provided on the mounting plate 1. A cavity 4 is provided inside the knife disc 3, and a plurality of connecting rods 5 are slidably passed through the circumferential direction of the cavity 4. A scraper 6 is provided at one end of each connecting rod 5 after passing through the cavity 4 outward, and a receiving groove for receiving the scraper 6 is provided on the circumferential outer wall of the knife disc 3, and the receiving groove corresponds to the scraper 6 one by one. A knife selection assembly for driving the corresponding scraper 6 to extend out of the receiving groove is also provided on the mounting plate 1, and the lifting assembly is provided on the movable platform 2. The lifting assembly is used to drive the mounting plate 1 to rise or fall in the vertical direction. The movable platform 2 is the main structure of the coating machine, which includes a paint supply system, a traveling wheel and other components. During the construction process, when the scraper 6 needs to be replaced, the driving component is started, and the driving component drives the cutter disc 3 to rotate so that the required scraper 6 is directly below the cutter disc 3. At this time, the scraper 6 is located in the receiving groove, and the knife selection component is started. The knife selection component pushes the connecting rod 5 to move in the direction away from the cavity 4 of the cutter disc 3, so that the scraper 6 extends out of the receiving groove, and then the overall height of the mounting plate 1 can be fine-tuned by the lifting component. The receiving groove serves to store the scraper 6 to prevent the unused scraper 6 from being exposed. The unused scraper 6 can also be protected from being damaged or accidentally touched when exposed to the outside and causing a safety accident. In this embodiment, the scrapers 6 on different connecting rods 5 can be scrapers 6 of the same type or scrapers 6 of different types. The device drives the cutter disc 3 to rotate through the driving component so that the required tool is directly below, and then the tool is pushed out of the receiving slot through the tool selection component and its horizontal height is fine-tuned through the lifting component to complete the tool changing operation. The whole process is convenient and fast. By installing different scrapers 6 on the connecting rod 5, different construction needs are met, and it has a wide range of applications.

[0023] like Figure 2 、 3 As shown in Figure 5, further, the knife selection assembly includes: a first motor 7, the first motor 7 is fixedly mounted on the mounting plate 1, a through hole is provided on the cutter disc 3 and is connected to the cavity 4, a cam 8 is provided after the output end of the first motor 7 extends into the cavity 4 of the cutter disc 3 through the through hole, and each connecting rod 5 is provided with a reset assembly on one end located in the cavity 4 to drive it to abut against the cam 8. In this example, the first motor 7 is fixedly mounted on the bottom of the mounting plate 1, and the cam 8 can be an eccentric wheel. When it is necessary to push the corresponding scraper 6 out of the receiving groove, the first motor 7 is started, and the first motor 7 drives the protruding end of the cam 8 to rotate to the side of the corresponding connecting rod 5, so that it pushes the connecting rod 5 toward the end away from the cavity 4 of the cutter disc 3, thereby allowing the connecting rod 5 to push the corresponding scraper 6 out of the receiving groove, making it easier to use the scraper 6.

[0024] like Figure 5 As shown, each reset assembly further includes a spring 9, each spring 9 being sleeved on a corresponding connecting rod 5. One end of the spring 9 abuts the inner wall of the cavity 4 of the cutter disc 3, and the other end of the spring 9 is fixedly connected to the outer wall of the connecting rod 5. When changing the blade, after the cutter disc 3 rotates a certain angle, the protruding end of the cam 8 no longer abuts the connecting rod 5 corresponding to the scraper 6 that is no longer in use. At this time, the spring 9 pushes the scraper 6 back into the receiving groove, thereby preventing safety accidents caused by accidental collision.

[0025] like Figure 1-5 As shown, further, the driving assembly includes: a second motor 10, the second motor 10 is fixedly mounted on the mounting plate 1, a gear 11 is provided on the output end of the second motor 10, a bearing 12 is fixedly mounted on the bottom of the mounting plate 1, a connecting cylinder 13 is fixedly mounted on the end of the cutter disc 3 facing the movable platform 2, the connecting cylinder 13 is rotatably connected to the bearing 12, an outer gear ring 14 is fixedly sleeved on the outer wall of the connecting cylinder 13, and the outer gear ring 14 is meshed with the gear 11. In this embodiment, the second motor 10 is embedded in the top of the mounting plate 1. When the cutter disc 3 is driven to rotate to replace the scraper 6 to be used, the second motor 10 is started, the second motor 10 drives the gear 11 to rotate, and the rotation of the gear 11 drives the outer gear ring 14 meshed with it to rotate, so that the connecting cylinder 13 drives the cutter disc 3 to rotate, thereby changing the position of the scraper 6 in different areas on the cutter disc 3.

[0026] like Figure 2 As shown, further, the output end of the first motor 7 horizontally passes through the connecting cylinder 13 and extends into the cavity 4 of the cutter disc 3. In this embodiment, the connecting cylinder 13 rotates horizontally via the bearing 12. The connecting cylinder 13 is connected to the center of the cutter disc 3. The output end of the first motor 7 horizontally passes through the connecting cylinder 13 and enters the cavity 4 of the cutter disc 3 without contacting the connecting cylinder 13. This ensures that the rotation of the cam 8 driven by the first motor 7 and the rotation of the cutter disc 3 driven by the second motor 10 do not interfere with each other.

[0027] like Figure 1 、 2 4, further, a third motor 15 is fixedly mounted on the movable platform 2. A screw rod 16 is vertically and rotatably mounted in a mounting groove. The screw rod 16 is threadedly connected to the mounting plate 1. The output end of the third motor 15 is fixedly connected to the screw rod 16. When adjusting the horizontal height of the mounting plate 1, the third motor 15 is started, and the third motor 15 drives the screw rod 16 to rotate. The screw rod 16 drives the mounting plate 1 threadedly connected thereto to rise or fall along the length direction of the screw rod 16, thereby facilitating the worker to adjust the horizontal height of the scraper 6 at any time.

[0028] like Figure 2 、 3As shown in Figure 5, the embodiment further includes two support rods 17, which are symmetrically arranged at both ends of the mounting plate 1. One end of the two support rods 17 is connected to the bottom of the mounting plate 1, and the other ends of the two support rods 17 are rotatably provided with rollers 18. Guide grooves 19 are symmetrically opened at one end of the movable platform 2 facing the mounting plate 1, and each roller 18 is movably connected to the corresponding guide groove 19. In this embodiment, the two support rods 17 are respectively arranged at both ends of the bottom of the mounting plate 1. As the mounting plate 1 rises or falls, the rollers 18 on the two support rods 17 roll in the guide grooves 19. The two support rods 17 are arranged between the mounting plate 1 and the movable platform 2, acting as triangular supports, making the mounting plate 1 less likely to bend during long-term use, thereby improving the overall strength.

[0029] like Figure 4 As shown, further, a guide block 20 is fixedly provided at one end of the mounting plate 1 facing the movable platform 2, and the guide block 20 is slidably disposed in the guide groove 19. The guide block 20 is fixedly connected to the mounting plate 1 and guides the movement of the mounting plate 1, making the mounting plate 1 more stable during the ascent or descent process and reducing the generation of jitter.

[0030] like Figure 2 、 3 As shown in Figures 5 and 6, a vertical rod 21 is fixed to the bottom of the mounting plate 1. A horizontal rod 22 is fixed to the end of the vertical rod 21 extending vertically downward away from the mounting plate 1. The two ends of the horizontal rod 22 are respectively connected to the two support rods 17. In this embodiment, each support rod 17 is provided with a connecting block, and the horizontal rod 22 passes horizontally through the two connecting blocks. When the mounting plate 1 is raised or lowered, the vertical rod 21 drives the horizontal rod 22 to rise or fall as well, so that the horizontal rod 22 drives the two support rods 17 to rise or fall stably, thereby improving the supporting strength of the support rods 17 on the mounting plate 1 and preventing deformation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
