Description

Technical Field

[0001] The invention belongs to the technical field of laser engraving demonstration platforms, and in particular relates to an automatic feeding color laser engraving demonstration platform and a use method thereof. Background Art

[0002] The imaging principle of a color laser printer is similar to that of a black and white laser printer. Both use laser scanning to form a latent image on the drum, which then absorbs toner and transfers the toner to the printing paper. The only difference is that a black and white laser printer only has black toner, while a color laser printer uses four colors of toner: yellow, magenta, cyan, and black. The laser engraving demonstration platform is used to demonstrate the imaging effect of laser engraving.

[0003] However, the existing laser marking demonstration platform has the following shortcomings:

[0004] 1. The existing laser marking demonstration platform is generally modified from a laser marking machine, and its feeding structure generally adopts the same replaceable powder box structure as the laser marking machine. However, since the laser marking demonstration platform needs to print for a long time, the laser marking demonstration platform with a replaceable powder box structure needs to replace the powder box frequently, which will affect the normal use of the laser marking demonstration platform;

[0005] 2. The toner in the replaceable powder box structure in laser engraving is generally unevenly distributed or needs to be manually shaken for uniform distribution. After the powder box structure is replaced, the toner in the powder box is evenly transported to the developing roller through the sponge roller. Therefore, after the shell-type powder box replacement structure is cancelled, a feeding structure that evenly distributes the toner is required. Summary of the invention

[0006] The present invention provides an automatic feeding color laser engraving demonstration platform and a method of use, aiming to solve the problem mentioned in the above background technology that the laser engraving demonstration platform with a replaceable powder box structure needs to frequently replace the powder box, which affects the normal use of the laser engraving demonstration platform, and after the shell powder box replacement structure is cancelled, a feeding structure for evenly distributing the carbon powder needs to be set.

[0007] The present invention is implemented as follows: an automatic feeding color laser engraving demonstration platform comprises a display stand, a material storage shell is provided on the top of the display stand, a mounting shell is provided on the top of the material storage shell, buckles are fixedly connected on both sides of the material storage shell, blocks are fixedly connected on both sides of the mounting shell, two blocks correspond to two buckles, a stirring bin is fixedly connected to the top wall inside the mounting shell, a feeding pipe is provided on the top of the stirring bin, the feeding pipe runs through the mounting shell, and a stirring mechanism for stirring carbon powder is provided inside the stirring bin;

[0008] A feeding mechanism for evenly feeding carbon powder is provided at the bottom of the mixing bin.

[0009] Preferably, the stirring mechanism comprises a rotating shaft and a fixed shell, the rotating shaft is arranged inside the stirring chamber, both ends of the rotating shaft are rotatably connected to the inner wall of the stirring chamber, the outer periphery of the rotating shaft is fixedly connected with a stirring rod, and the number of the stirring rods is set to be multiple;

[0011] A spiral stirring bar is arranged on the outer periphery of the rotating shaft, and the surface of the spiral stirring bar is fixedly connected to the ends of a plurality of stirring rods.

[0012] Carbon powder is added into the mixing chamber through the feed pipe, and then the transmission rod is driven to rotate by starting the stepper motor. At the same time, the transmission rod will synchronously drive multiple stirring rods to rotate through the rotating shaft, so that the carbon powder in the mixing chamber is broken up by the stirring rods. By controlling the stepper motor to rotate back and forth in the forward and reverse directions, the stirring rods on the periphery of the transmission rod can drive the spiral stirring bars to rotate back and forth in the forward and reverse directions, and then the carbon powder that enters the mixing chamber and contacts the spiral stirring bars is transported back and forth to both ends of the mixing chamber. In this process, the carbon powder in the mixing chamber can cover the bottom of the mixing chamber.

[0013] Preferably, the feeding mechanism includes a quantitative feeding structure for carbon powder, a uniform conveying structure for carbon powder, and a driving structure for simultaneously driving the quantitative feeding structure and the uniform conveying structure.

[0014] Preferably, the quantitative material discharging structure comprises a baffle, the baffle is arranged at the bottom of the mixing bin, a plurality of mounting grooves are opened on the surface of the baffle, and the plurality of mounting grooves are distributed in a linear array;

[0015] A rotating rod is provided through the middle of the installation groove, both ends of the rotating rod extend to the outside of the baffle, the rotating rod is rotatably connected to the installation groove, both ends of the rotating rod are fixedly connected to driven gears, a conveying roller is fixedly connected to the outer periphery of the rotating rod, a plurality of conveying grooves are opened on the outer periphery of the conveying roller, and the outer wall of the conveying roller is arranged in close contact with the installation groove;

[0016] Under the action of gravity, the carbon powder in the mixing bin will fall to the top of the baffle, and a part of the carbon powder on the top of the baffle will enter the conveying groove on the periphery of the conveying roller in the conveying groove. When the conveying roller rotates, it will drive multiple conveying grooves on its periphery to rotate synchronously. When the conveying groove at the top of the conveying roller rotates to the bottom of the conveying roller, the carbon powder in the conveying groove will be synchronously conveyed to the bottom of the conveying roller. At this time, the carbon powder will fall under the action of gravity. Therefore, the carbon powder is quantitatively discharged by controlling the number of rotations of the conveying roller.

[0017] Preferably, the uniform conveying structure comprises a threaded rod, the threaded rod is arranged inside the mounting shell, both ends of the threaded rod are rotatably connected to the inner wall of the mounting shell, the outer circumference of the threaded rod is threadedly connected to a conveying frame, a feed trough is provided on the top of the conveying frame, a discharge trough is provided on the bottom of the conveying frame, the feed trough and the discharge trough are connected, racks are fixedly connected to both sides of the top of the conveying frame, two racks are respectively arranged on both sides of the baffle, and a plurality of driven gears are matched with the racks;

[0018] When the threaded rod rotates, it drives the conveying frame threadedly connected to it to move horizontally. The moving direction of the conveying frame is controlled by controlling the rotation direction of the threaded rod. When the conveying frame is moving, the two racks on the top of the conveying frame will respectively drive the driven gears on both sides of the baffle to rotate, thereby driving the conveying roller connected to the driven gear to rotate. At this time, the conveying roller conveys the carbon powder to the conveying frame through the feed trough, and the carbon powder in the conveying frame will be discharged from the discharge trough under the action of gravity and fall into the storage shell. The conveying frame moves horizontally around the outer periphery of the threaded rod to evenly spread the carbon powder in the storage shell, thereby avoiding uneven distribution of the carbon powder in the storage shell, which causes the magnetic roller to be unable to evenly take the carbon powder in the storage shell.

[0019] Preferably, the driving structure comprises a driven shaft, a moving frame and a rotating rod, wherein the driven shaft is arranged between the fixed shell and the mounting shell, one end of the driven shaft is rotatably connected to the inner wall of the fixed shell, and the other end of the driven shaft is fixedly connected to the threaded rod;

[0020] One end of the outer circumference of the driven shaft is fixedly connected to the first rotating disk, and the other end of the outer circumference of the driven shaft is fixedly connected to the second rotating disk. The side wall of the first rotating disk is fixedly connected to the first driven gear ring, and the side wall of the second rotating disk is fixedly connected to the second driven gear ring. One side of the second driven gear ring is meshed and connected to two reversing gears. A connecting frame is provided between the two reversing gears, and the connecting frame runs through the two reversing gears. The two reversing gears are both rotatably connected to the connecting frame, and the end of the connecting frame is fixedly connected to the side wall of the mounting shell;

[0021] A moving plate is slidably connected to the middle of the driven shaft, a first driving gear ring is fixedly connected to one side of the moving plate, a second driving gear ring is fixedly connected to the other end of the moving plate, the first driven gear ring corresponds to the first driving gear ring, the two reversing gears correspond to the second driving gear ring, a driving gear ring is fixedly connected to the outer periphery of the moving plate, and a connecting plate is also rotatably connected to the outer periphery of the moving plate;

[0022] The moving frame is slidably sleeved on the outer circumference of the threaded rod, and a connecting rod is fixedly connected between the moving frame and the connecting plate;

[0023] The end of the rotating rod is rotatably connected to the inner wall of the fixed shell, the outer periphery of the rotating rod is fixedly connected to a driving gear, the driving gear is meshed and connected to the driving gear ring, and the thickness of the driving gear is greater than the thickness of the driving gear ring;

[0024] The outer periphery of the rotating rod is also fixedly connected to a driven transmission wheel, the top of the driven transmission wheel is provided with an active transmission wheel, the active transmission wheel is fixedly connected to the transmission rod, and a transmission belt is sleeved between the active transmission wheel and the driven transmission wheel;

[0025] The driving rod and the active driving wheel are driven to rotate by starting the stepping motor, and the active driving wheel drives the driven driving wheel and the rotating rod to rotate through the transmission belt. When the rotating rod rotates, it drives the driving gear ring and the moving disk to rotate through the driving gear. When the first active gear ring on one side of the moving disk is meshed and connected with the first driven gear ring, the moving disk rotates and drives the first driven gear ring and the first rotating disk to rotate through the first active gear ring. At the same time, the first rotating disk drives the threaded rod to rotate through the driven shaft, thereby driving the conveying frame to move horizontally.

[0026] When the conveying frame moves to one end of the threaded rod, it will squeeze one end of the moving frame, and the moving frame will drive the moving disk to move through the connecting rod and the connecting plate, and at the same time, the first active gear ring on one side of the moving disk will be disengaged from the second active gear ring, and at the same time, the second active gear ring on the other side of the moving disk will be meshed and connected with the two steering gears, so that when the moving disk rotates, the second driven gear ring and the second rotating disk are driven to rotate in the opposite direction through the two steering gears, and at the same time, the second rotating disk will drive the threaded rod to rotate in the opposite direction through the driven shaft, thereby driving the conveying frame to move in the opposite direction, and when the driving frame moves to the other end of the threaded rod, it will squeeze the other end of the moving frame, and the threaded rod will rotate in the opposite direction again. Therefore, the moving frame is automatically moved back and forth laterally around the outer periphery of the threaded rod through the above method, thereby automatically and evenly conveying the carbon powder in the mixing bin to the storage shell.

[0027] Preferably, both ends of the moving frame are fixedly connected with first magnets, one side of the two first magnets is provided with a second magnet, the two second magnets are fixedly connected to the inner wall of the mounting shell, and the two second magnets correspond to the two first magnets respectively;

[0028] The first magnet and the second magnet are arranged so that when the moving frame drives the moving disk to move out of the drive, the magnetism of the first magnet and the second magnet enables the moving frame to fit with the inner wall of the mounting shell when the power is disconnected, thereby driving the moving disk to move to the specified position and connect with the driving structure.

[0029] The present invention provides a method for using an automatic feeding color laser engraving demonstration platform, comprising the following steps:

[0030] S1. The toner required for printing is transported into the stirring chamber through the feeding pipe, and then the toner in the stirring chamber is stirred by the rotating stirring rod to break up the toner in the stirring chamber. By controlling the stepper motor to rotate forward and reversely, the stirring rod on the periphery of the transmission rod can drive the spiral stirring bar to rotate forward and reversely, and then the toner that enters the stirring chamber and contacts the spiral stirring bar is transported back and forth to the two ends of the stirring chamber, and in this process, the toner in the stirring chamber can cover the bottom of the stirring chamber;

[0031] S2. The toner in the mixing chamber is quantitatively transported back and forth into the storage shell through the feeding mechanism to ensure that the toner in the storage shell is in a flat state, so that the magnetic powder can evenly transport the toner to the laser printing area during printing.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. By setting up a quantitative feeding structure, the carbon powder in the mixing bin is quantitatively transported to the storage shell, so as to avoid the accumulation of excessive carbon powder in the storage shell and the insufficient carbon powder in the storage shell to meet the normal use of the device;

[0034] 2. By setting a uniform conveying structure, the reciprocating conveying frame evenly conveys the carbon powder in the mixing bin to the storage shell, so that the carbon powder in the storage shell remains flat, so that the carbon powder in the storage shell can be evenly conveyed to the surface of the laser printing structure;

[0035] 3. The toner is automatically delivered to the storage shell through the cooperation of the stirring mechanism and the feeding mechanism, avoiding the addition of new toner by replacing the toner box. The cooperation of the stirring mechanism and the feeding mechanism can avoid the inaccurate amount of toner delivered, and also avoid the subsequent printing operation being affected by the uneven distribution of the delivered toner in the storage shell.

[0069] The present invention provides a method for using an automatic feeding color laser engraving demonstration platform, comprising the following steps:

[0070] S1. The toner required for printing is transported into the stirring chamber 15 through the feeding pipe 16, and then the toner in the stirring chamber 15 is stirred by the rotating stirring rod 23 to break up the toner in the stirring chamber 15. By controlling the stepping motor 25 to rotate forward and reversely, the stirring rod 23 on the periphery of the transmission rod 26 can drive the spiral stirring bar 27 to rotate forward and reversely, and then the toner that enters the stirring chamber 15 and contacts the spiral stirring bar 27 is transported to both ends of the stirring chamber 15, and in this process, the toner in the stirring chamber 15 can cover the bottom of the stirring chamber 15;

[0071] S2. The toner in the mixing chamber 15 is quantitatively transported back and forth into the storage shell 11 through the feeding mechanism 3 to ensure that the toner in the storage shell 11 is in a flat state, so that the magnetic powder can evenly transport the toner to the laser printing area during printing.

[0072] The working principle and use process of the present invention:

[0073] Carbon powder is added into the stirring chamber 15 through the feeding pipe 16, and then the driving rod 26 is driven to rotate by starting the stepper motor 25. At the same time, the driving rod 26 will synchronously drive the multiple stirring rods 23 to rotate through the rotating shaft 21, so that the carbon powder in the stirring chamber 15 is dispersed by the stirring rods 23. By controlling the stepper motor 25 to rotate back and forth in the forward and reverse directions, the stirring rods 23 on the periphery of the driving rod 26 can drive the spiral stirring bars 27 to rotate back and forth in the forward and reverse directions, and then the carbon powder that enters the stirring chamber 15 and contacts the spiral stirring bars 27 is transported back and forth to the two ends of the stirring chamber 15. In this process, the carbon powder in the stirring chamber 15 can cover the bottom of the stirring chamber 15.

[0074] When the transmission rod 26 rotates, the active transmission wheel 3318 is driven to rotate. At the same time, the active transmission wheel 3318 drives the driven transmission wheel 3317 and the rotating rod 333 to rotate through the transmission belt 3319. When the rotating rod 333 rotates, it drives the driving gear ring 3313 and the moving disk 3310 to rotate through the driving gear 3316. When the first active gear ring 3311 on one side of the moving disk 3310 is meshed and connected with the first driven gear ring 336, when the moving disk 3310 rotates, it drives the first driven gear ring 336 and the first rotating disk 334 to rotate through the first active gear ring 3311. At the same time, the first rotating disk 334 drives the threaded rod 321 to rotate through the driven shaft 331.

[0075] When the threaded rod 321 rotates, the conveying frame 322 threadedly connected thereto is driven to move horizontally. When the conveying frame 322 moves, the two racks 325 at the top of the conveying frame 322 respectively drive the driven gears 314 on both sides of the baffle 311 to rotate, thereby driving the conveying rollers 315 connected to the driven gears 314 to rotate.

[0076] When the conveying roller 315 rotates, it will drive the multiple conveying grooves 316 on its periphery to rotate synchronously. When the conveying groove 316 at the top of the conveying roller 315 rotates to the bottom of the conveying roller 315, the carbon powder in the conveying groove 316 will be synchronously conveyed to the bottom of the conveying roller 315. At this time, the carbon powder will fall under the action of gravity and be transported to the conveying frame 322 through the feeding groove 323. The carbon powder in the conveying frame 322 will be discharged from the discharging groove 324 under the action of gravity and fall into the storage shell 11. The conveying frame 322 moves laterally around the outer periphery of the threaded rod 321 to evenly spread the carbon powder in the storage shell 11.

[0077] When the conveying frame 322 moves to one end of the threaded rod 321, it squeezes one end of the moving frame 332, and the moving frame 332 drives the moving plate 3310 to move through the connecting rod 3315 and the connecting plate 3314. At the same time, the first active gear ring 3311 on one side of the moving plate 3310 is disengaged from the second active gear ring 3312, and the second active gear ring 3312 on the other side of the moving plate 3310 is meshed and connected with the two steering gears, so that when the moving plate 3310 rotates, the second driven gear ring 3311 is driven by the two steering gears. The gear ring 337 and the second rotating disk 335 rotate in opposite directions. At the same time, the second rotating disk 335 drives the threaded rod 321 to rotate in opposite directions through the driven shaft 331, thereby driving the conveying frame 322 to move in opposite directions. When the driving frame moves to the other end of the threaded rod 321, it squeezes the other end of the moving frame 332. At this time, the threaded rod 321 rotates in opposite directions again. Therefore, the moving frame 332 automatically moves back and forth laterally around the outer periphery of the threaded rod 321 in the above manner, thereby automatically and evenly conveying the carbon powder in the mixing bin 15 to the storage shell 11.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
