A punching device for license plate sealing that is easy to clean debris

Abstract

The present invention relates to the technical field of license plate punching, and discloses a license plate sealing punching device that is convenient for cleaning debris. As the license plate is removed after punching, a scraper plate moves from one end of a workbench to the other end of the workbench to scrape the license plate processing surface of the workbench. Before the scraper plate moves to the top sheet position, the scraper plate resets the top sheet so that debris on the top sheet is located on the license plate processing surface of the workbench, so that the scraper plate scrapes away the debris. In addition, the reset of the punching head passes through a cleaning head, which uses the reset movement of the punching head to clean the punching head, so as to clean any debris that may be on the punching head onto the workbench, so that the scraper plate also performs the debris scraping process, thereby preventing debris from remaining on the workbench and affecting the quality of the processed license plate, thereby increasing the maintenance cycle of the punching device and improving the practicality of the punching device.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] As introduced in the background art, in order to solve the deficiencies in the prior art, the present application proposes a punching device for sealing a license plate that is convenient for cleaning debris.

[0033] In a typical embodiment of the present application, Figures 1-9 As shown, a punching device for a license plate seal that is convenient for cleaning debris includes a body 1, a punching mechanism 2 disposed on the body 1, and a cleaning mechanism 3 disposed on the punching mechanism 2. The punching mechanism 2 includes a workbench 21 and a punch head 213.

[0034] The cleaning mechanism 3 includes a scraper plate 33, a top plate 36, and a cleaning head 313. The scraper plate 33 is movably mounted on the workbench 21. The top plate 36 is slidably engaged with the workbench 21 and is located directly below the punching head 213. The cleaning head 313 is fixedly mounted on the machine body 1 and is adjacent to the punching head 213.

[0035] After the punching head 213 is pressed against the workbench 21 to punch the license plate, the top sheet 36 receives the punched debris and moves it to the workbench 21. When the license plate is removed, the cleaning head 313 cleans the reset punching head 213, and the scraping plate 33 scrapes the workbench 21. At the same time, the scraping plate 33 moves to the front of the top sheet 36, and the top sheet 36 is removed from the workbench 21, so that the scraping plate 33 scrapes off the debris on the top sheet 36.

[0036] When using the present invention:

[0037] The license plate is intermittently fed to the workbench 21 by the feeding device. After the license plate is moved to the workbench 21, the punching head 213 moves down, so that the punching head 213 punches the license plate on the workbench 21. After the punching process, the punched debris is pushed into the workbench 21 by the punching head 213 on the top sheet 36. Then the punching head 213 moves up and resets, and the license plate moves out of the workbench 21. As the license plate moves out, the scraping plate 33 moves from one end of the workbench 21 to the other end of the workbench 21, so that the scraping plate 33 is on the license plate processing surface of the workbench 21. At the same time, before the scraping plate 33 moves to the position of the top sheet 36, the scraping plate 33 will reset the top sheet 36 so that the debris on the top sheet 36 is located on the license plate processing surface of the workbench 21, so that the scraping plate 33 can scrape away the debris. In addition, the reset of the punch head 213 passes through the cleaning head 313. The cleaning head 313 uses the reset movement of the punch head 213 to clean the punch head 213, so as to clean the debris that may exist on the punch head 213 onto the workbench 21, so that the scraping plate 33 can also perform the debris scraping process;

[0038] As the license plate is removed after punching, the scraper plate 33 moves from one end of the workbench 21 to the other end of the workbench 21 to scrape the license plate processing surface of the workbench 21, and before the scraper plate 33 moves to the position of the top plate 36, the scraper plate 33 will reset the top plate 36 so that the debris on the top plate 36 is located on the license plate processing surface of the workbench 21, so that the scraper plate 33 scrapes away the debris, and the reset of the punching head 213 passes through the cleaning head 313, and the cleaning head 313 uses the reset movement of the punching head 213 to clean the punching head 213 to clean the debris that may exist on the punching head 213 to the workbench 21, so that the scraper plate 33 can scrape off the debris together to avoid debris remaining on the workbench 21 affecting the quality of the processed license plate, thereby increasing the maintenance cycle of the punching device and improving the practicality of the punching device.

A plurality of auxiliary rollers 24 are rotatably cooperated on the body 1. The auxiliary rollers 24 are symmetrically and evenly distributed on both sides of the workbench 21. The auxiliary rollers 24 are all located between the rails on both sides of the conveyor belt 23, and the top of the auxiliary roller 24 and the license plate processing surface of the workbench 21 are located in the same horizontal plane.

[0040] Furthermore, a servo motor 25 is fixedly installed in the machine body 1. The servo motor 25 is a double-shaft motor. Toothed belts 26 are tensioned on both side shafts of the servo motor 25 and on both end shafts of the traction roller 22 on one side.

[0041] When punching the license plate, the servo motor 25 is started, the servo motor 25 drives the toothed belt 26 to rotate, the toothed belt 26 drives the traction roller 22 to rotate, and the traction roller 22 drives the conveyor belt 23 to rotate, so that the conveyor belt 23 drives the license plate to move on the auxiliary roller 24 to transfer the license plate to the workbench 21.

[0042] Furthermore, a plurality of punching holes 27 are provided on the workbench 21, and the punching holes 27 are all opposite to the punching head 213.

[0043] Furthermore, a column 210 is fixedly installed on the body 1, and the column 210 is opposite to the workbench 21. A punch 211 is fixedly installed on the top of the column 210. The hydraulic rod of the punch 211 passes through the column 210. A suspension 212 is fixedly installed on the hydraulic rod of the punch 211. The suspension 212 is located directly above the workbench 21. A plurality of punch heads 213 are fixedly installed on the bottom surface of the suspension 212. The sizes of the punch heads 213 are all adapted to the punching holes 27.

[0044] Among them, after the license plate is transferred to the workbench 21, the servo motor 25 stops running and the rotating arm cylinder 28 is started. The rotating arm cylinder 28 drives the fixed arm 29 to rotate, so that the fixed arm 29 fixes the license plate to the workbench 21, and then the punching machine 211 on the column 210 is started. The punching machine 211 drives the suspension 212 to move, and the suspension 212 drives the punching head 213 to move, so that the punching head 213 moves toward the workbench 21 to punch the license plate, and at the same time, the debris after punching is pushed into the punching hole 27.

[0045] Furthermore, the cleaning mechanism 3 also includes a track groove 31. A track groove 31 is provided in the middle part of the workbench 21. Limit rails 32 are fixedly installed on the wall surfaces on both sides of the track groove 31. Scraping plates 33 are provided between the limit rails 32. The scraping plates 33 are movably matched with the limit rails 32 on both sides. The width of the scraping plates 33 is the same as the width of the punching hole 27. The connection between the scraping plates 33 and the limit rails 32 is rotatably matched with a movable adapter frame 34. An electric push rod 35 is movably provided in the body 1. The fixed rod of the electric push rod 35 is rotatably matched in the body 1, and the extension rod of the electric push rod 35 is fixedly connected to the movable adapter frame 34.

[0046] Among them, as the punched license plate is moved out, the electric push rod 35 is started, the electric push rod 35 extends the extension rod to drive the movable adapter frame 34 to move, and the movable adapter frame 34 drives the scraper plate 33 to move on the limit rail 32. Through the rotation of the electric push rod 35 body and the rotational connection between the movable adapter frame 34 and the scraper plate 33, the scraper plate 33 is stably attached to the workbench 21 for scraping processing.

[0047] Furthermore, a top plate 36 is slidably fitted in the punching holes 27. The top surface of the top plate 36 is located in the same horizontal plane as the license plate processing surface of the workbench 21. A return spring 37 is provided in the punching holes 27. One end of the return spring 37 is connected to the punching hole 27. The other end of the return spring 37 is connected to the top plate 36. A plurality of accommodating grooves 38 are provided in the workbench 21. The accommodating grooves 38 are all connected to the punching holes 27. The accommodating grooves 38 are all located on one side of the punching holes 27. 8 are fixedly installed with a reset telescopic rod 39, and a limiting member 310 is fixedly installed on the extension rod of the reset telescopic rod 39. The limiting members 310 extend into the punching hole 27. The top portion of the limiting member 310 located in the punching hole 27 is an arc-shaped structure, and the bottom end portion of the limiting member 310 located in the punching hole 27 is a flat structure. When the top sheet 36 moves downward from the top of the limiting member 310, the top sheet 36 pushes the limiting member 310 to move the top sheet 36 to the bottom of the limiting member 310.

[0048] Furthermore, the portion of the limiting member 310 located in the punching hole 27 does not affect the normal expansion and contraction of the reset spring 37. By providing the limiting member 310, after the top sheet 36 is pressed into the punching hole 27, the top sheet 36 is restricted by the limiting member 310 and cannot be reset immediately, ensuring that the top sheet 36 will be reset with debris only after the license plate is removed, avoiding debris from adhering to the license plate, and ensuring the stable operation of the punching device.

[0049] Furthermore, a plurality of toggle grooves 311 are provided on the workbench 21, and the toggle grooves 311 are symmetrically distributed on both sides of the track groove 31, and the accommodating grooves 38 on both sides are communicated with the toggle grooves 311 on both sides. A toggle member 312 is provided in the toggle groove 311, and the toggle member 312 is rotatably cooperated with the scraper plate 33. The toggle member 312 is an "L"-shaped structure, so that when the toggle member 312 moves with the scraper plate 33, the toggle member 312 is first located in the same vertical plane as the limiting member 310, and a plurality of cleaning heads 313 are fixedly installed on the column 210, and the cleaning heads 313 all pass through the suspension 212, and the cleaning heads 313 are all attached to the punching head 213.

[0050] Furthermore, a torsion spring is provided between the toggle member 312 and the scraper plate 33. The elastic limit of the torsion spring is greater than the elastic limit of the reset telescopic rod 39, so that when the toggle member 312 pushes the limiting member 310 to move, the toggle member 312 will not rotate first. After the limiting member 310 moves to the bottom, the toggle member 312 will rotate to pass through the limiting member 310, thereby ensuring the stability of the device operation.

[0051] Furthermore, a collecting funnel 314 is fixedly installed on the body 1, and the collecting funnel 314 is adjacent to the workbench 21. The collecting funnel 314 passes through the wall of the body 1, so that the collecting funnel 314 collects the debris pushed off the workbench 21 by the scraper plate 33. A collecting box 315 is movably installed in the body 1, and the collecting box 315 is located directly below the collecting funnel 314.

[0052] When the punching head 213 punches, the punching head 213 presses the debris and the top sheet 36 into the punching hole 27, and the top sheet 36 pushes the limiting member 310, so that the limiting member 310 moves in the receiving groove 38, so that the top sheet 36 moves below the limiting member 310 and is restricted by the limiting member 310 and cannot be reset. Then, as the punched license plate moves out, the moving scraper plate 33 drives the toggle member 312 to move, so that the toggle member 312 pushes the limiting member 310 to move, and the top sheet 36 is no longer restricted by the limiting member 310. 0 and is reset by the reset spring 37 to drive the debris to move to the license plate processing surface of the workbench 21. After the limiting member 310 moves to the bottom, the toggle member 312 deflects to pass through the limiting member 310, and the limiting member 310 is reset by the reset telescopic rod 39. After the debris moves to the workbench 21, the scraper plate 33 pushes the debris on the workbench 21 to push the debris into the collecting funnel 314. The debris passes through the collecting funnel 314 and falls into the collection box 315 for unified collection.

[0053] Working principle:

[0054] The license plate is intermittently fed to the workbench 21 by the feeding device. After the license plate is moved to the workbench 21, the punching head 213 moves down, so that the punching head 213 punches the license plate on the workbench 21. After the punching process, the punched debris is pushed into the workbench 21 by the punching head 213 on the top sheet 36. Then the punching head 213 moves up and resets, and the license plate moves out of the workbench 21. As the license plate moves out, the scraping plate 33 moves from one end of the workbench 21 to the other end of the workbench 21, so that the scraping plate 33 is on the license plate processing surface of the workbench 21. At the same time, before the scraping plate 33 moves to the position of the top sheet 36, the scraping plate 33 will reset the top sheet 36 so that the debris on the top sheet 36 is located on the license plate processing surface of the workbench 21, so that the scraping plate 33 can scrape away the debris. In addition, the reset of the punch head 213 passes through the cleaning head 313. The cleaning head 313 uses the reset movement of the punch head 213 to clean the punch head 213, so as to clean the debris that may exist on the punch head 213 onto the workbench 21, so that the scraping plate 33 can also perform the debris scraping process;

[0055] When punching the license plate, the servo motor 25 is started, which drives the toothed belt 26 to rotate, which drives the traction roller 22 to rotate, which drives the conveyor belt 23 to rotate, so that the conveyor belt 23 drives the license plate to move on the auxiliary roller 24, so as to transfer the license plate to the workbench 21. After the license plate is transferred to the workbench 21, the servo motor 25 stops running, and the rotating arm cylinder 28 is started, which drives the fixed arm 29 to rotate, so that the fixed arm 29 fixes the license plate to the workbench 21, and then the punching machine 211 on the column 210 is started, and the punching machine 211 drives the suspension 212 to move, and the suspension 212 drives the punching head 213 to move, so that the punching head 213 moves toward the workbench 21 to punch the license plate, and at the same time, the punched debris is pushed into the punching hole 27;

[0056] As the punched license plate is removed, the electric push rod 35 is activated, and the electric push rod 35 extends the extension rod to drive the movable adapter frame 34 to move, and the movable adapter frame 34 drives the scraping plate 33 to move on the limit rail 32. Through the rotation of the electric push rod 35 body and the rotational connection between the movable adapter frame 34 and the scraping plate 33, the scraping plate 33 is stably attached to the workbench 21 for scraping.

[0057] When the punch head 213 punches, the punch head 213 presses the debris and the top sheet 36 into the punch hole 27, and the top sheet 36 pushes the limiting member 310, causing the limiting member 310 to move in the receiving groove 38, so that the top sheet 36 moves below the limiting member 310 and is restricted by the limiting member 310 and cannot be reset. Then, as the punched license plate is removed, the moving scraper plate 33 drives the toggle member 312 to move, causing the toggle member 312 to push the limiting member 310 to move, and the top sheet 36 is no longer restricted by the limiting member 310. The limiting member 310 is limited and reset by the reset spring 37 to drive the debris to move to the license plate processing surface of the workbench 21. After the limiting member 310 moves to the bottom, the toggle member 312 deflects to pass through the limiting member 310, and the limiting member 310 is reset by the reset telescopic rod 39. After the debris moves to the workbench 21, the scraper plate 33 pushes the debris on the workbench 21 to push the debris into the collection funnel 314. The debris passes through the collection funnel 314 and falls into the collection box 315 for unified collection.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
