Description

Technical Field

[0001] This utility model relates to the field of edge scraper technology, specifically to an automatically retractable edge scraper. Background Technology

[0002] After the material is processed, in order to improve the quality, excess parts or burrs on the edges of the material must be removed. At this time, an edge scraper is used. It is mainly used to ensure that the edges of the workpiece are flat and smooth to meet specific processing requirements.

[0003] However, traditional scraping equipment has a fixed scraper structure and cannot automatically control the scraper to extend and retract to handle workpieces of different lengths. Usually, it is necessary to manually stop the machine first, and then manually adjust the position of the scraper or workpiece to adapt before restarting the machine for scraping, which is very inconvenient and affects the overall processing efficiency. In order to solve the above problems, the inventor proposed an automatically extendable scraper. Utility Model Content

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an automatically retractable scraper, comprising a processing table, a support frame fixedly installed at the top of the processing table, symmetrically distributed threaded rods rotatably installed at one end of the support frame, a threaded push plate threaded on the outer side of the threaded rods, a scraper fixedly connected to one end of the threaded push plate, a belt drivingly connected to the outer side of the threaded rods, a motor fixedly installed at one end of the support frame, one end of one of the threaded rods fixedly connected to the drive end of the motor, symmetrically distributed electric telescopic rods fixedly installed at the top of the processing table, a push frame fixedly connected to one end of the electric telescopic rods, and a workpiece body movably installed on the inner side of the push frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The screw rod is rotated by a motor, and the two screw rods rotate synchronously by the belt. The rotation of the screw rod controls the movement of the screw push plate, which in turn pushes the scraper to move and adjust. This makes it easier to control the extension and retraction of the scraper, which is convenient for scraping edges of workpieces of different lengths. Compared with manual adjustment, it is smoother and faster, improving processing efficiency.

[0012] 2. By controlling the cooperation of the water pump and the booster pump, water is drawn from the water tank into the T-shaped pipe and then sprayed out by the nozzle. This facilitates heat dissipation and cooling during the scraping of the scraper and the workpiece body, preventing the scraper from overheating and causing irreversible damage due to continuous use, and further effectively improving the service life of the scraper.

[0020] A cross brace 12 is fixedly installed at the top of the support frame 11, and a water tank 21 is fixedly installed at the top of the cross brace 12. A T-shaped pipe 22 is fixedly inserted into one end of the cross brace 12. The top end of the T-shaped pipe 22 is fixedly connected to the water tank 21. Spray nozzles 23 with equal spacing are fixedly installed on the outside of the T-shaped pipe 22. A water pump 24 is fixedly installed on the inside of the water tank 21. A booster pump 25 is fixedly connected to one end of the water pump 24.

[0021] By adopting the above technical solution, water is drawn from the water tank 21 into the T-shaped pipe 22 and then sprayed out by the nozzle 23 by controlling the cooperation of the water pump 24 and the booster pump 25. This facilitates heat dissipation and cooling when scraping the scraper 15 and the workpiece body 20, preventing the scraper 15 from overheating and causing irreversible damage due to continuous use, and further effectively improving the service life of the scraper 15.

[0022] The bottom surface of the push frame 19 is fixedly equipped with an array of pulleys 26, and the top surface of the processing table 1 is provided with symmetrically distributed sliding grooves 27. One end of the pulley 26 is slidably engaged with the inner side of the sliding groove 27.

[0023] By adopting the above technical solution, the smoothness of the movement of the push frame 19 is improved by setting the pulley 26 to slide in the slide groove 27.

[0024] One end of the scraper 15 is fixedly connected to a guide plate 28, and a guide groove 29 is provided on the inner side of the support frame 11. One end of the guide plate 28 is slidably engaged with the inner side of the guide groove 29.

[0025] By adopting the above technical solution, the guiding force is strengthened by setting the guide plate 28 to slide in the guide groove 29.

[0026] One end of each threaded rod 13 is fixedly fitted with symmetrically distributed pulleys 30, and the opposite end of each pulley 30 is in contact with the belt 16.

[0027] By adopting the above technical solution, the belt 16 is stably limited by setting the pulley 30.

[0028] A movable cover 31 is movably installed on the top of the water tank 21.

[0029] By adopting the above technical solution, the water inlet of the water tank 21 can be sealed by setting the movable cover 31 to prevent dust from entering.

[0030] Working principle: First, the workpiece body 20 is placed on the push frame 19. Then, the electric telescopic rod 18 is controlled to push the push frame 19 to move. The push frame 19 drives the workpiece body 20 to move. At this time, if the extension and retraction of the scraper 15 is to be adjusted, the threaded rod 13 can be rotated by the motor 17. The two threaded rods 13 rotate synchronously by the action of the belt 16. The rotation of the threaded rod 13 controls the movement of the screw push plate 14. The screw push plate 14 then pushes the scraper 15 to move and adjust, thus making it easy to control the extension and retraction of the scraper 15. This is convenient for scraping edges of workpiece bodies 20 of different lengths. Compared with manual adjustment, it is smoother and faster, improving processing efficiency. During the continuous scraping process, the water pump 24 and the booster pump 25 are controlled to draw water from the water tank 21 into the T-shaped pipe 22 and then spray it out by the nozzle 23. This facilitates heat dissipation and cooling of the scraper 15 and the workpiece body 20 during scraping, preventing the scraper 15 from overheating and causing irreversible damage due to continuous use, and further effectively improving the service life of the scraper 15.
