[0021] 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.
[0022] Example 1
[0023] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: a self-cleaning device for a large-size workbench, comprising...
[0024] Two cleaning mechanisms are respectively set at both ends of the workbench 1 and on both sides of the workpiece 5. They include two plate seats 15 that are slidably set on the front and rear surfaces of the workbench 1, mounting columns 3 fixed on the top surface of the plate seats 15, scraper 8 installed between the two mounting columns 3 and slidably located on the top surface of the workbench 1, large sprocket 7 fixed on the outer surface of the plate seats 15, and two sets of chain drive assemblies set on the front and rear surfaces of the workbench 1.
[0025] In this embodiment, preferably, the chain drive assembly includes a drive motor 12 bolted to one side surface of the workbench 1, a drive wheel 121 mounted on the output end of the drive motor 12, a transmission rod 17 mounted on one side of the workbench 1, a small sprocket 13 rotatably mounted on the end of the transmission rod 17, a sprocket mounting base 18 bolted to the end surface of the workbench 1, a middle sprocket 6 rotatably mounted on the surface of the sprocket mounting base 18 via a rotating shaft, and a short chain 14 sleeved between the middle sprocket 6, the small sprocket 13, and the drive wheel 121. A center plate 19 corresponding to the sprocket mounting base 18 is bolted to the center of both the front and rear surfaces of the workbench 1, and two center sprockets 191 are rotatably mounted on the surface of the center plate 19. It also includes a long chain 11 fitted between the middle sprocket 6 and one of the central sprockets 191, with the large sprocket 7 located inside the long chain 11 and locked together with it. This allows the subsequent drive motor 12 to drive the short chain 14 to rotate via the drive wheel 121, and the short chain 14 to drive the middle sprocket 6 to rotate, causing the long chain 11 to start running. Because the rack on the large sprocket 7 is locked together with the long chain 11, and the large sprocket 7 is fixed to the plate base 15 and cannot rotate on its own, the long chain 11 and the plate base 15 run synchronously. This causes the long chain 11 to move laterally along with the large sprocket 7 and the plate base 15, thus enabling the mounting column 3 and the scraper 8 to move laterally, allowing the scraper 8 to effectively scrape and clean the top of the workbench 1.
[0026] In this embodiment, preferably, the two central sprockets 191 on the surface of the central seat plate 19 are both supported and installed by bearings, and the two central sprockets 191 do not interfere with each other. They are used to support and install the long chains 11 in the two cleaning mechanisms, so that the two cleaning mechanisms can operate separately without interfering with each other.
[0027] In this embodiment, preferably, a tray 16 is fixed to the inner surface of the plate base 15 relative to the top of the workbench 1, and the tray 16 is slidably located on the top surface of the workbench 1, which can effectively support the scraper 8 at the bottom of the scraper 8. At the same time, a sliding wheel embedded in the T-shaped groove on the top surface of the workbench 1 is installed at the bottom of the tray 16, and the front and rear of the sliding wheel are equipped with protective scrapers to avoid the problem of the sliding wheel under the tray 16 getting stuck due to the debris of the workbench 1 falling into the T-shaped groove.
[0028] In this embodiment, preferably, the inner surface of the plate base 15 is also equipped with rollers, and the rollers roll in the sliding grooves on the front or rear surface of the worktable 1, so that the plate base 15 can slide smoothly.
[0029] In this embodiment, preferably, it also includes a rear panel 4 fixed behind the workbench 1, two side panels 2 fixed to the two sides of the workbench 1 respectively, a front panel 9 fixed to the front of the workbench 1, and a front baffle 10, which can form a enclosure around the workbench 1. The cleaning mechanism is located inside the side panels 2, the rear panel 4, and the front panel 9, so as to collect and receive the debris scraped off by the scraper 8 during cleaning.
[0030] Example 2
[0031] Please see Figures 1 to 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a strip-shaped slot 31 for inserting the end of the scraper 8 is welded and fixed to the surface of the mounting column 3. A limiting structure is also provided between the strip-shaped slot 31 and the scraper 8. The limiting structure includes an L-shaped elastic card 32 fixed to both sides of the strip-shaped slot 31, a hemispherical block 33 disposed inside the L-shaped elastic card 32, and a circular hole 81 opened on the surface of the scraper 8 and corresponding to the hemispherical block 33. The L-shaped elastic card 32 and the hemispherical block 33 are both made of spring steel and have a certain elasticity, which can undergo a certain elastic deformation. The end of the hemispherical block 33 is inserted into the circular hole 81, which can effectively limit the scraper 8 and ensure the installation stability of the scraper 8.
[0032] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
