Description

Technical Field

[0001] The invention relates to the technical field of scraping processing, and in particular to an electric scraper for a roller surface. Background Art

[0002] Conductive rollers are rollers used for conducting electricity, usually made of conductive materials such as metal or carbon fiber. They are commonly used in the electronics manufacturing and printing industries, mainly for transmitting current and controlling static electricity. Conductive rollers can be used to disperse charges onto printed materials to prevent static interference and printing errors. They can also be used to manufacture electronic components such as semiconductor chips and circuit boards.

[0003] A scraper is a common scraping tool and can be used in a variety of ways. Moving the scraper back and forth on the surface of an object to remove a layer of the surface is a common working method.

[0004] The scraper mechanism with adjustable scraper pressure disclosed in Chinese patent CN209681332U includes a push block, and two first baffles are fixedly connected to the front of the push block. The tops of the two first baffles are provided with a cross through hole, and the inner wall of the first baffle is slidably connected with a cross rod through the cross through hole, and the bottoms of the two cross rods are fixedly connected with a scraper, and the top of the scraper is fixedly connected with a fixed cylinder, and the inner surface of the fixed cylinder is slidably connected with two sliding plates, and the opposite surfaces of the two sliding plates are fixedly connected with springs, and the bottom of the lower sliding plate overlaps with the top of the scraper, and the top of the upper sliding plate is rotatably connected with a threaded rod, and the front of the push block is fixedly connected with a second baffle, and the top of the second baffle is provided with a threaded through hole, and the surface of the threaded rod is threadedly connected with the inner wall of the second baffle through the threaded through hole.

[0005] However, compared with the prior art and the comparative solution, it can be seen that the scraper mechanism still has the following problems during actual use: When scraping the surface of the conductive roller, since the roller surface is arc-shaped, the roller surface is prone to deflect along the arc during the scraping process, resulting in deflection. Once scraped off, the angle between the scraper and the roller surface also changes due to the change in scraping direction, resulting in different forces at different positions of the roller surface, resulting in uneven scraping effects at different positions of the roller surface, and thus making the scraping effect of the roller surface poor. Summary of the invention

[0006] The present invention provides an electric scraper for a roller surface to solve the above technical problems.

[0007] The electric roller scraper of the present invention adopts the following technical solution: it comprises a fixing mechanism, a connecting seat is arranged on the fixing mechanism, a first connecting frame is arranged on the connecting seat, and a scraper, a driving member and a moving wheel are arranged on the first connecting frame; The fixing mechanism comprises a contact frame, on which a ball and a strap are arranged, on which a buckle is arranged, on which a first ratchet ring is arranged, and between which a first elastic member is arranged; A second ratchet ring is arranged at the bottom of the connecting seat, a sliding tube is arranged on the connecting seat, a first latching tooth ring is arranged at one end of the sliding tube, and a second elastic member is arranged between the first latching tooth ring and the connecting seat; A second toothed ring is provided on one side of the first connecting frame, a knob is provided on the side of the first connecting frame away from the second toothed ring, a third elastic member is provided between the knob and the first connecting frame, a sliding groove is provided on the first connecting frame, a first gear and a second gear are rotatably connected on the first connecting frame, a third gear is provided on the axis of the first gear, and a swash plate is provided on the axis of the second gear; The scraper is fixedly mounted on the slide block, and a roller is arranged on the slide block.

[0011] Furthermore, the first connecting frame is rotatably connected to the connecting seat.

[0012] Further, the position of the second latch tooth ring corresponds to the position of the first latch tooth ring, and the second latch tooth ring is adapted to the first latch tooth ring.
