[0046] The following is for reference. Figures 1 to 4 This invention describes a paint cleaning device according to an embodiment of the present invention.

[0047] like Figures 1 to 4 As shown, the paint cleaning device according to an embodiment of the present invention includes a frame 100, a drive assembly 200, and a scraping assembly 300.

[0048] The frame 100 is used to hold the oil drum 700 and enable the oil drum 700 to rotate around its own axis. In other words, after the oil drum 700 is placed on the frame 100, it can rotate around its own axis. The drive assembly 200 is located on the frame 100 to drive the oil drum 700 to rotate around its own axis. The scraping assembly 300 includes a lifting part 301 and a scraper part 302. The lifting part 301 is movably mounted on the frame 100. Specifically, the lifting part 301 can move vertically or its direction of movement can be slightly inclined relative to the vertical. The scraper section 302 is connected to the lifting section 301. The scraper section 302 includes a first scraper 303 and a second scraper 304. One end of the second scraper 304 is connected to the bottom end of the first scraper 303. After the oil drum 700 is placed on the frame 100, the lifting section 301 can be lowered so that the first scraper 303 is in contact with the inner circumferential surface of the oil drum 700. The extension direction of the first scraper 303 can be parallel to the axial direction of the oil drum 700 or slightly inclined relative to the axial direction of the oil drum 700. The second scraper 304 is in contact with the inner bottom surface of the oil drum 700. The extension direction of the second scraper 304 can be radial to the oil drum 700 or slightly inclined relative to the radial direction of the oil drum 700.

[0049] In this embodiment, when it is necessary to clean the paint residue on the inner surface of the oil drum 700, the oil drum 700 is placed on the frame 100, and then the lifting part 301 is lowered so that the first scraper 303 is in contact with the inner circumferential surface of the oil drum 700 and the second scraper 304 is in contact with the inner bottom surface of the oil drum 700. Then, the drive assembly 200 is activated, and the drive assembly 200 drives the oil drum 700 to rotate around its own axis, so that the oil drum 700 and the first scraper 303 move relative to each other along the circumference of the oil drum 700, and the oil drum 700 and the second scraper 304 move relative to each other along the circumference of the oil drum 700. In this way, the first scraper 303 can scrape off the paint residue on the inner circumferential wall of the oil drum 700, and the second scraper 304 can scrape off the paint residue on the inner bottom surface of the oil drum 700. The operation is more convenient, more time-saving and labor-saving, and the cleaning is more comprehensive and thorough.

[0050] It should be noted that, in order to make the second scraper 304 scrape the paint on the inner bottom surface of the oil drum 700 more comprehensively and thoroughly, the length of the second scraper 304 can be greater than or equal to the radius of the inner bottom surface of the oil drum 700.

[0051] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the frame 100 is provided with a turntable 101, which can rotate around its own axis. The turntable 101 is provided with a plurality of clamping parts 102, which are arranged around the circumference of the turntable 101. The turntable 101 is used to place the oil drum 700, and the plurality of clamping parts 102 are used to abut against the outer peripheral wall of the oil drum 700 and make the oil drum 700 coaxial with the turntable 101.

[0052] In this embodiment, after the oil drum 700 is placed on the turntable 101, multiple clamping parts 102 are operated. The multiple clamping parts 102 abut against the outer peripheral wall of the oil drum 700, so that the oil drum 700 and the turntable 101 are relatively fixed and the oil drum 700 and the turntable 101 are coaxial. In this way, the oil drum 700 can rotate around its own axis when the turntable 101 rotates. The structure is simple, the operation is convenient, and the oil drum 700 is placed more stably.

[0053] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first scraper 303 extends along the axial direction of the turntable 101, and the second scraper 304 extends along the radial direction of the turntable 101.

[0054] In this embodiment, the oil drum 700 is placed on the turntable 101, and the lifting part 301 is lowered so that the first scraper 303 is attached to the inner circumferential surface of the oil drum 700 and the second scraper 304 is attached to the inner bottom surface of the oil drum 700. The extension direction of the first scraper 303 is the axial direction of the oil drum 700, and the extension direction of the second scraper 304 is the radial direction of the oil drum 700. This makes it easier and more thorough to scrape off the paint residue on the inner surface of the oil drum 700, and the scraping effect is better.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, the lifting unit 301 includes a main body 305 and an adjusting frame 306. The main body 305 is movably mounted on the frame 100. The adjusting frame 306 is connected to the main body 305 and can be adjusted by moving radially along the turntable 101. The first scraper 303 is connected to the adjusting frame 306 and can be adjusted by moving axially along the turntable 101.

[0056] In this embodiment, the adjusting frame 306 can be adjusted to move radially along the turntable 101, thereby enabling the second scraper 304 to move radially along the oil drum 700, thus making it suitable for oil drums 700 with different radius sizes. The first scraper 303 can be adjusted to move axially along the turntable 101, thereby enabling the first scraper 303 to move axially along the oil drum 700, thus making it suitable for oil drums 700 with different length sizes, resulting in better practicality.

[0057] In some embodiments of this utility model, such as Figure 3 As shown, the main body 305 is provided with a first groove 307, which extends radially along the turntable 101. The adjusting frame 306 is connected to the main body 305 by a first fastener 308, which passes through the first groove 307. The adjusting frame 306 is provided with a second groove 309, which extends axially along the turntable 101. The first scraper 303 is connected to the adjusting frame 306 by a second fastener 310, which passes through the second groove 309.

[0058] In this embodiment, by positioning the first fastener 308 at different positions along the length of the first groove 307, the adjusting frame 306 can be moved radially along the turntable 101 for adjustment. By positioning the second fastener 310 at different positions along the length of the second groove 309, the first scraper 303 can be moved axially along the turntable 101 for adjustment. The structure is simple, the operation is convenient, and the connection is relatively stable.

[0059] It should be noted that in some embodiments of this utility model, the adjusting frame 306 and the first scraper 303 can also be moved and adjusted in other ways, for example, by means of a hydraulic cylinder.

[0060] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive assembly 200 includes a mounting frame 201, two drive rollers 202, a transmission belt 203, and a drive motor 204. The two drive rollers 202 are rotatably mounted on the mounting frame 201 and arranged circumferentially along the axis of the turntable 101. The axial direction of the drive rollers 202 is parallel to the axial direction of the turntable 101. The transmission belt 203 is installed between the two drive rollers 202 and is used to fit against the outer peripheral wall of the oil drum 700. The drive motor 204 is located on the mounting frame 201 and connected to one of the drive rollers 202.

[0061] In this embodiment, starting the drive motor 204 causes one of the drive rollers 202 to rotate. Both drive rollers 202 then move the transmission belt 203 along its length. The transmission belt 203, through friction with the outer wall of the oil drum 700, causes the oil drum 700 to rotate around its own axis. Because the contact area between the transmission belt 203 and the outer wall of the oil drum 700 is large, the effect of driving the oil drum 700 to rotate is better. Furthermore, because the transmission belt 203 can be bent and deformed, it can be adapted to oil drums 700 of different radii, thus improving its practicality.

[0062] It should be noted that in other embodiments of this utility model, the drive component 200 may also have other structures. For example, the drive belt 203 may not be provided, and the outer peripheral wall of the drive roller 202 may be directly attached to the outer peripheral wall of the oil drum 700. When the drive roller 202 rotates, the oil drum 700 can also be driven to rotate by the friction between the drive roller 202 and the outer peripheral wall of the oil drum 700.

[0063] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the drive assembly 200 also includes a first telescopic member 205, which is disposed on the frame 100 and connected to the mounting bracket 201 to drive the mounting bracket 201 to move radially along the turntable 101. For example, the first telescopic member 205 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, etc. When the oil drum 700 is not placed on the turntable 101, the first telescopic member 205 drives the mounting bracket 201 to move outward to facilitate the placement of the oil drum 700. After the oil drum 700 is placed, the first telescopic member 205 drives the mounting bracket 201 to move toward the oil drum 700, so that the transmission belt 203 fits tightly against the outer peripheral wall of the oil drum 700. This makes it more convenient to use and more applicable to oil drums 700 with different radius sizes, thus improving its practicality.

[0064] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, there are two drive components 200, located on opposite sides of the axis of the turntable 101. In this embodiment, this arrangement not only improves the effect of driving the oil drum 700 to rotate, but also makes the force on the oil drum 700 more even during rotation, and both sides are adhered to by the transmission belt 203, thus making it less likely to tip over and rotating more smoothly.

[0065] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the turntable 101 is provided with a plurality of mounting blocks 103 along its circumference. The clamping part 102 includes a screw 104 and an elastic clamping block 105. The screw 104 is rotatably mounted on the mounting block 103 and extends radially along the turntable 101. The elastic clamping block 105 is located at one end of the screw 104 near the axis of the turntable 101. For example, a handle can be provided at the end of the screw 104 away from the elastic clamping block 105. The elastic clamping block 105 can be made of elastic rubber or elastic plastic. In this embodiment, by operating the handle to rotate the screw 104, the elastic clamping block 105 can be moved and adjusted radially along the turntable 101, thereby clamping or releasing the oil drum 700. The operation is simple and convenient, and the clamping effect of the oil drum 700 is better. Moreover, the elastic clamping block 105 is an elastic structure, which not only clamps the oil drum 700 better, but also makes it less likely to damage the oil drum 700.

[0066] It should be noted that in some other embodiments of this utility model, the clamping part 102 may also be other structures, for example, the elastic clamping block 105 may be moved directly by a hydraulic cylinder.

[0067] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the lifting unit 301 is equipped with a collar 311. The paint cleaning device also includes a base 400, a second telescopic member 500, and an oil extraction pipe 600. The frame 100 is rotatably connected to the base 400 about a horizontal axis. The second telescopic member 500 is located between the base 400 and the frame 100 to drive the frame 100 to rotate. The oil extraction pipe 600 passes through the collar 311 to extract paint from the oil tank 700 when the frame 100 rotates to make an angle between the axis of the oil tank 700 and the vertical. For example, the second telescopic member 500 can be a hydraulic cylinder or a pneumatic cylinder, etc. The oil extraction pipe 600 can move along its own length relative to the collar 311, and the oil extraction pipe 600 can be connected to an oil pump.

[0068] After the paint is scraped off, the second telescopic component 500 can be activated. The second telescopic component 500 controls the frame 100 to rotate around the horizontal axis relative to the base 400. The frame 100 then drives the oil drum 700 to rotate so that the axis of the oil drum 700 forms an angle with the vertical. In this case, the inner bottom surface of the oil drum 700 is inclined relative to the horizontal plane, and the scraped paint will accumulate at the bottom end of the inclined direction of the inner bottom surface of the oil drum 700. Then, the oil suction pipe 600 can be pulled out so that the bottom end of the oil suction pipe 600 is close to the bottom end of the inclined direction of the inner bottom surface of the oil drum 700. Then, the oil pump can be activated to extract the scraped paint from the oil drum 700 through the oil suction pipe 600, making paint cleaning simpler and more convenient.

[0069] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the second telescopic member 500 is fixedly connected to the base 400, and the frame 100 is slidably mounted with a slider 106. The slider 106 slides radially along the turntable 101, and the second telescopic member 500 is hinged to the slider 106. In this embodiment, this arrangement can prevent interference between the second telescopic member 500 and the frame 100 when the frame 100 rotates.

[0070] Of course, it should be noted that in some other embodiments of this utility model, the two ends of the second telescopic member 500 may be hinged to the base 400 and the frame 100 respectively.

[0071] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a lead screw 107 is rotatably mounted on the frame 100. The lead screw 107 extends along the axial direction of the turntable 101. The lifting part 301 is slidably mounted on the frame 100 and threadedly connected to the lead screw 107. The frame 100 may be equipped with a lifting motor 108, which is connected to the lead screw 107.

[0072] Start the lifting motor 108, which will drive the lead screw 107 to rotate. The lead screw 107 will drive the lifting part 301 to rise and fall through the threaded connection with the lifting part 301.

[0073] It should be noted that the lifting unit 301 can also be raised and lowered in other ways, such as by extending and retracting the hydraulic cylinder.

[0074] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
