[0002] Floor paint is mainly made of oil, wood, color, solvent, etc., and is mainly divided into: epoxy floor paint, polyurethane floor paint, anti-corrosion floor paint, elastic floor paint, anti-static floor paint, anti-slip floor paint and load-bearing floor paint. In current construction, in order to improve the efficiency of scraping, people have designed automatic floor paint scraping machines.

[0003] For example, patent number CN216042474U discloses an automatic floor paint scraping machine, in which a first drive motor is mounted on a swing arm, a first pulley is connected to the upper end of each support member, a third pulley is mounted on the swing arm on one side of the first pulley, and a fourth pulley is mounted below the third pulley. The two first pulleys and the fourth pulley are connected in series via a synchronous belt, and the first drive motor is driven and connected to the third pulley via the synchronous belt. When the swing arm swings to the left or right end point, the first drive motor drives the scraper to reverse its rotation so that the scraping surface of the scraper is always consistent with the swing direction. A second drive motor is mounted on the frame, and a second pulley is mounted on the top end of the main drive shaft. The second drive motor is driven and connected to the second pulley. In the above structure, although the scraper can reverse, the angle of the scraper cannot be adjusted according to the actual terrain, making it inflexible. In addition, the use of a larger second pulley to drive the swing arm requires a suitable high-power motor for the second drive motor, which increases manufacturing costs and is not conducive to energy saving.

[0034] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0035] See Figures 1 to 7 The present invention provides an angle-adjustable automatic floor paint scraper, comprising a frame 1, a swing arm 2 rotatably mounted on the frame 1, a scraper 3 mounted on the swing arm 2, and a main pulley 41. The frame 1 is primarily constructed from a plurality of welded rods and plates and is primarily used to support and mount the various components. The main pulley 41 is drivably connected to the scraper 3 to drive the scraper 3 in reverse direction. The swing arm 2 is provided with an angle adjustment mechanism that drives the main pulley 41 to rotate the scraper 3 to adjust its angle.

[0036] See Figure 1 、 Figure 3 and Figure 4The angle adjustment mechanism includes a driven gear 51 coaxially arranged with the main pulley 41, a drive shaft 52 located on one side of the driven gear 51, and a driving gear 53 sliding on the drive shaft 52. The driven gear 51 is located on the lower side of the main pulley 41 and can slide along the drive shaft 52. When the drive shaft 52 rotates, it can drive the driven gear 51 to rotate. The driving gear 53 can mesh with the driven gear 51. When adjusting the angle, the driving gear 53 slides along the drive shaft 52 until it meshes with the driven gear 51. The rotation of the drive shaft 52 drives the driving gear 53 to rotate, and the driving gear 53 drives the driven gear 51 to rotate. The driven gear 51 drives the main pulley 41 to rotate, and the main pulley 41 drives the scraper 3 to rotate to adjust the angle. This structure adds an angle adjustment mechanism. Through the cooperation of the driven gear, driving gear, telescopic rod and shift lever, it can adjust the angle of the scraper according to the actual terrain, thereby improving the scraping quality and making it more flexible to use.

[0037] In some embodiments, as Figures 3 to 5 As shown, the angle adjustment mechanism also includes a telescopic rod 54 installed on one side of the drive shaft 52 and a lever 55 hinged on the swing arm 2. The telescopic rod 54 is connected to the driving gear 53 through the lever 55. The telescopic rod 54 can drive the driving gear 53 to slide along the drive shaft 52 through the lever 55. When adjusting the angle, the telescopic rod 54 moves, and the telescopic rod 54 drives the lever 55 to rotate. The lever 55 shifts the driving gear 53 so that it engages with the driven gear 51. Among them, one end of the lever 55 is provided with a shifting portion, which abuts against the driving gear 53 and is provided with a U-shaped groove 551 that is plugged into the drive shaft 52; the other end of the lever 55 is provided with a waist-shaped groove for hinged connection with the telescopic rod 54. The telescopic rod 54 is provided with a hinge shaft, which is placed in the waist-shaped groove (the hinge shaft and waist-shaped groove are not shown in the figure).

[0038] In some embodiments, as Figure 5 As shown, a spring stopper 521 is provided at the end of the drive shaft 52. A first spring (not shown) is installed between the spring stopper 521 and the driving gear 53. The first spring always forces the driving gear 53 to move away from the driven gear 51 and serves to reset the driving gear 53. Under normal circumstances, the driving gear 53 is disengaged from the driven gear 51 under the action of the first spring.

[0039] In some embodiments, as Figures 3 to 5As shown, a linear motor 57, a first motor 58, and a second motor 42 are mounted on the swing arm 2. The telescopic rod 54 is located on the linear motor 57, the drive shaft 52 is located on the first motor 58, and the main pulley 41 and the driven gear 51 are both located on the motor shaft of the second motor 42. With this structure, a manual switch can be provided on the frame 1 to control the operation of the linear motor 57 and the first motor 58, thereby adjusting the angle of the scraper 3. Alternatively, a remote control switch can be used to control the operation of the linear motor 57 and the first motor 58, which is more convenient to operate and also facilitates adjustment during equipment operation.

[0040] In some embodiments, as Figure 2 As shown, a third motor 11 and a gear reducer 12 are mounted within the frame 1. The third motor 11 and the gear reducer 12 are connected via a belt drive. Pulleys are mounted on each of the third motor 11 and the gear reducer 12, and the two pulleys are connected via a belt. One end of the swing arm 2 is mounted on the output shaft of the gear reducer 12. Frame 1 is symmetrically mounted with travel switches 13 on either side of the swing arm 2. The travel switches facilitate control of the swing arm's swing amplitude. By replacing the traditional large drive pulley with a gear reducer, the third motor driven by the gear reducer can use a lower power, which is beneficial for energy conservation, reducing manufacturing costs, and reducing the overall weight of the equipment, while also achieving a more stable speed.

[0041] In some embodiments, as Figure 6 and Figure 7 As shown, the scraper 3 comprises a support member 31 rotatably mounted on the swing arm 2, a scraper rod 32 slidably mounted within the support member 31, a connection seat 33 being threadedly connected to the bottom of the scraper rod 32, and a scraper body 34 being hingedly connected to the connection seat 33. A retainer 35 is mounted on the scraper rod 32, and a plurality of balls 36 are evenly distributed on the outer surface of the retainer 35. The retainer 35 slides within the support member 31. A second spring 37 is installed between the connection seat 33 and the retainer 35. The use of a retractable scraper 3 is primarily due to the unevenness of the ground surface, allowing the scraper to adapt to different ground heights, thereby expanding its range of use.

[0042] In some embodiments, as Figure 3 and Figure 6As shown, the upper end of the scraper 3 is connected to the first pulley 43, and a second pulley 44 is installed on one side of the first pulley 43. The first pulley 43 is connected to the second pulley 44 via a synchronous belt, and the second pulley 44 is connected to the main pulley 41 via a synchronous belt. In this structure, when reversing, the second motor 42 drives the main pulley 41 to rotate, the main pulley 41 drives the second pulley 44 to rotate, the second pulley 44 drives the first pulley 43 to rotate, and the first pulley 43 drives the scraper 3 to rotate and reverse direction; when the swing arm swings to the left or right end point, the second motor drives the scraper to rotate 180 degrees so that the scraping surface of the scraper is always consistent with the swing direction, ensuring the scraping quality; to prevent interference, when adjusting the scraper angle, avoid adjusting it when the swing arm swings to the left or right end point to prevent the first motor 58 and the second motor 42 from operating simultaneously.

[0043] In some embodiments, as Figure 3 As shown, the swing arm 2 includes a traction rod 21 connected to the frame 1 and a support rod 22 detachably connected to the traction rod 21. The scraper 3 is mounted at the rear end of the support rod 22. A support frame 23 is mounted on the support rod 22, and a universal wheel 24 is mounted at the bottom of the support frame 23. This structure adopts a segmented structure for easy transportation. The support frame provides stable support, ensuring stable and reliable movement of the scraping mechanism.

[0044] In some embodiments, as Figure 1 and Figure 2 As shown, a driving wheel assembly 14 and a driven wheel assembly 15 are mounted on either side of the bottom of the frame 1. A stepper motor is mounted on the bottom of the frame 1 and is in driving connection with the driving wheel assembly 14. The stepper motor, the driving wheel assembly 14, and the driven wheel assembly 15 cooperate to drive the frame 1 to move. A material storage bin 61 is provided on the frame 1. A pump body 62 is mounted on one side of the material storage bin 61. A material suction pipe 63 of the pump body 62 can extend into the material storage bin 61.

[0045] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0046] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
