Description

Technical Field

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

[0002] A conductive roller is a roller 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 printing materials to prevent static interference and printing errors. They can also be used in the manufacture of electronic components, such as semiconductor chips and circuit boards.

[0003] A scraper is a common scraping processing instrument, and its usage methods are diverse. Among them, moving the scraper back and forth on the surface of an object to remove a layer of the object's surface is a common working method.

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

[0005] However, compared with the prior art and the comparative solutions, the following problems still exist in this scraper mechanism during actual use:

[0006] When scraping the surface of a conductive roller, since the roller surface is arc-shaped, it is prone to deflect along the arc-shaped roller surface during the scraping process, resulting in the situation of scraping deviation. And once scraping deviation occurs, due to the change in the scraping direction, the angle between the scraper and the roller surface also changes, so that the forces on different positions of the roller surface are different, resulting in uneven scraping effects on different positions of the roller surface, and further resulting in a poor scraping effect on the roller surface. Summary of the Invention

[0007] The present invention provides an electric scraper for a roller surface to solve the above technical problems.

[0008] An electric scraper for a roller surface of the present invention adopts the following technical solutions: including 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;

[0009] The fixing mechanism includes a contact frame, on which balls and a strap are arranged. A buckle is arranged on the strap, and a first ratchet ring is arranged on the contact frame. A first elastic member is arranged between the first ratchet ring and the contact frame;

A fixing bolt 603 is provided on the second connecting frame 601.

[0049] The working process is as follows:

[0050] S1. Before use, according to the scraping path required, rotate the rotating connection seat 2 along the direction of the ratchets on the first ratchet ring 105 and the second ratchet ring 201. The connection seat 2 drives the scraper 4 to rotate through the first connecting frame 3 to adjust the orientation of the scraper 4.

[0051] S2. When linear scraping is required, make the direction of the scraper 4 face the end face of the conductive roller to be scraped. When circular scraping is required, make the direction of the scraper 4 tangent to the roller surface. When spiral scraping is required, make the direction of the scraper 4 inclined relative to the axis of the conductive roller.

[0052] S3. Then, according to the scraping depth required, rotate the first connecting frame 3 through the knob 302 to drive the scraper 4 to rotate and adjust the angle between the scraper 4 and the roller surface.

[0053] S4. At this time, first pull the first connecting frame 3 through the knob 302, the third elastic member 303 contracts, the second ratchet ring 301 leaves the first ratchet ring 203 to release the limit on the first connecting frame 3, and then rotate the first connecting frame 3 through the knob 302. The first connecting frame 3 drives the scraper 4 to rotate to adjust the angle between the scraper 4 and the roller surface.

[0054] S5. After the adjustment is completed, loosen the knob 302, the third elastic member 303 rebounds to drive the first connecting frame 3 to reset, the second ratchet ring 301 engages with the first ratchet ring 203 to limit the first connecting frame 3 and fix the angle between the scraper 4 and the roller surface.

[0055] S6. Then loosen the fixing bolt 603 and rotate the second connecting frame 601 to make the moving wheel 6 contact the roller surface, and then tighten the fixing bolt 603 to limit the second connecting frame 601.

[0056] S7. During use, start the driving member 5. The driving member 5 drives the first gear 305 and the fifth gear 602 to rotate through the fourth gear 501. The first gear 305 drives the second gear 306 to rotate through the third gear 307. The second gear 306 drives the swash plate 308 to rotate. The swash plate 308 drives the slider 401 to reciprocate in the chute 304 through the roller 402. The slider 401 drives the scraper 4 to reciprocate to scrape the roller surface.

[0057] S8. At the same time, the fifth gear 602 drives the moving wheel 6 to rotate to push the scraper 4 to move and scrape the roller surface.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
