[0002] When replacing the resin of a light-curing 3D printer, the old resin needs to be cleaned out of the material box first, and then new resin is added. The resin is liquid and has a certain viscosity, so it is difficult to completely clean the resin out of the material box. Therefore, a material box with a resin cleaning function has appeared on the market. For example, the existing patent document with application number 202221667589.7 provides a scraper device for a light-curing 3D printer, which belongs to the technical field of light-curing 3D printers. It includes an installation box and a connecting seat. A servo motor is installed on one side of the installation box. Two sets of screw rods are installed on the inner sides of the installation box and the connecting seat. The outer surface of the screw rod is sleeved with a threaded block.

The utility model is provided with a screw rod, a servo motor, a threaded block, an electric heating wire, a rotating wheel, a transmission belt, a spring and a mounting portion. The rotation of the servo motor causes the screw rod to rotate, and then the rotating wheel and the transmission belt cooperate.
[0003] Taking the scraper device installed in the material box of the above-mentioned light-curing 3D printer as an example, although the scraper device is set to clean the resin inside the material box, as the scraper is used for a longer time, the resin on the outside of the scraper increases, causing the scraper to lose its function. However, the displacement control structure on which the scraper needs to be installed makes it difficult to disassemble and replace the scraper, affecting the use of the equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In this application, the plug board is inserted into the plug slot away from the power plug.

[0018] 3. In this application, the inclination angle of the scraper is the same as the inclination angle of the L-shaped plate close to the resin material box end, so the control drive component and the control component work together to place the scraper on the L-shaped plate and be supported by the L-shaped plate, control the pneumatic cylinder 2 to contract, and the support frame 6 moves away from the sealing frame.

[0033] 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.
[0034] Example: Figures 1-13As shown, the present invention provides a technical solution for a scraper device for a light-curing 3D printer that can be quickly replaced, including a light-curing 3D printer material box structure 1, the light-curing 3D printer material box structure 1 includes a resin material box 11, a heat conduction box 14 is arranged inside the resin material box 11, blade two 13 are fixedly installed on both sides of the heat conduction box 14, blade one 12 is fixedly installed on the bottom of one side of blade two 13, a sealing frame 15 is fixedly installed on the top of the heat conduction box 14, and a tool control structure 2 is arranged on the outside of the sealing frame 15, the tool control structure 2 includes a drive component installed on the outside of the light-curing 3D printer material box structure 1, two support frames three 26 driven by the drive component, two control components arranged on the two support frames three 26, and a support frame six 215 provided by the two control components near one end of the resin material box 11, and a power socket 224 and a plug board 225 are respectively arranged between the two support frames six 215 and the two ends of the sealing frame 15.
[0035] Specifically, blade two 13 is fixedly installed on both sides of the heat conduction box 14 arranged inside the resin material box 11, and the two blade twos 13 clean the front inner wall and the rear inner wall of the resin material box 11 respectively; a blade one 12 is fixedly installed on the bottom of one side of the heat conduction box 14, and the blade one 12 cleans the bottom wall of the inner cavity of the resin material box 11; a sealing frame 15 is fixedly installed on the top of the heat conduction box 14, and the length of the sealing frame 15 is longer than the distance between the front inner wall to the rear inner wall of the resin material box 11, and the sealing frame 15 supports and limits the scraper composed of the heat conduction box 14, the two blade twos 13 and the blade one 12; sliding grooves 19 are provided on both sides of the top of the resin material box 11, and the two limit blocks 18 arranged inside the two sliding grooves 19 are fixedly installed on the bottom of the sealing frame 15. Under the restriction and guidance of the two limit blocks 18 and the two sliding grooves 19, the sealing frame 15 and the scraper installed on the sealing frame 15 move horizontally left and right to avoid unnecessary wear between the scraper and the inner wall of the resin material box 11.
[0036] Specifically, a support frame 111 is fixedly installed at one end of the resin material box 11 away from the heat conduction box 14, and an L-shaped plate 3 is sleeved on the outside of the support frame 111. The L-shaped plate 3 can be removed from the outside of the support frame 111. The L-shaped plate 3 is used to support the scraper leaving the inside of the resin material box 11, providing convenience for the staff to manually hold and operate the scraper, reducing the possibility of the staff being injured by the scraper.
[0037] Specifically, plug-in slots 16 are provided on both sides of the sealing frame 15, and a power plug 17 is provided inside the plug-in slot 16 near the power socket 224. The power plug 17 fixedly connected to the sealing frame 15 is electrically connected to the heating wire 110 fixedly installed inside the thermal box 14. When the heating wire 110 is working, it heats the liquid inside the thermal box 14, thereby increasing the temperature of the thermal box 14, blade 2 13 and blade 1 12 made of materials with good thermal conductivity.
[0038] Specifically, the two output ends of the gear box 22 in the drive assembly are fixedly installed with a screw rod 23, and the support frame three 26 is sleeved on the outside of the adjacent screw rod 23 through a nut pair, and the outside of the screw rod 23 is rotatably sleeved with a support frame four 27, and the end of the screw rod 23 away from the gear box 22 is rotatably connected to the support frame two 25, and the support frame two 25 and the support frame four 27 are both fixedly connected to the resin material box 11, so that the screw rod 23 is supported and can rotate, and a guide rod 24 is fixedly installed between the support frame two 25 and the support frame four 27, and the guide rod 24 passes through the support frame three 26 to limit the support frame three 26. When the guide rod 24 is limited, the support frame three 26 can only move horizontally left and right, thereby ensuring the stability of the working movement of the support frame three 26.
[0039] Specifically, the two telescopic rods 210 in the control assembly are fixedly inserted on the support frame 3 26, and a support frame 5 212 is fixedly installed between the two telescopic rods 210. The telescopic rod 210 that can be extended and retracted limits the support frame 5 212, so that the support frame 5 212 can only move up and down. The top of the pneumatic cylinder 211 fixedly installed on one side of the support frame 3 26 is fixedly connected to the support frame 5 212. The pneumatic cylinder 211 is controlled to extend or retract, thereby controlling the up and down position of the support frame 5 212.
[0040] In addition, a pneumatic cylinder 213 and four telescopic rods 214 are fixedly inserted horizontally on the support frame 5 212, and a support frame 7 216 is fixedly installed between the four telescopic rods 214 in a control component. The support frame 7 216 cannot rotate relatively on one side of the support frame 5 212. The electromagnet 217 rotatably installed inside the support frame 7 216 is fixedly connected to the adjacent support frame 6 215. The electromagnet 217 is rotatably installed on the outer side of the piston end of the adjacent pneumatic cylinder 213. The control of the pneumatic cylinder 213 to extend or retract can control the front and rear positions of the electromagnet 217 and the support frame 6 215, and the rotation of the electromagnet 217 will not affect the normal operation of the pneumatic cylinder 213.
[0041] Under normal conditions, the electromagnet 217 is in working condition. The electromagnet 217 is fixed to the iron support frame 7 216 by magnetic force. At this time, the support frame 7 216 cannot rotate, the electromagnet 217 cannot rotate, the support frame 6 215 to which the support frame 7 216 is fixedly connected cannot rotate, and the relative position between the support frame 6 215 and the support frame 5 212 cannot change.
[0042] In this application, the tool control structure 2 installed outside the resin material box 11 meets the working requirements of the scraper clamping and fixing, the translation drive of the scraper, and the rotation of the scraper. The specific working method is as follows:
[0043] Place the scraper inside the resin material box 11, control the smooth surface of the heat conduction box 14 without the structure installed to fit the left inner wall of the resin material box 11, and put the scraper into the working position;
[0044] Then, the two pneumatic cylinders 1 211 in the two control components work and extend, and the two support frames 5 212 move up. The support frame 5 212 drives the support frame 6 215 to move up through the pneumatic cylinder 2 213. The two support frames 6 215 move to the two ends of the sealing frame 15. The power socket 224 fixedly installed on one of the support frames 6 215 and the plug board 225 fixedly installed on the other support frame 6 215 are aligned with the two plug slots 16. Then, the two pneumatic cylinders 213 are controlled to work and extend, so that the two support frames 6 215 are against the sealing frame 15 and close to the plug slot 16 of the power socket 224. 6 is provided with a power plug 17, and the power socket 224 is sleeved on the outside of the power plug 17. The power socket 224 is used to connect the electric wire, so that the heating wire 110 is energized to heat the scraper. The plug board 225 is inserted into the plug slot 16 away from the power plug 17. Under the action of the two support frames 215, the power socket 224 and the plug board 225, the sealing frame 15 is clamped and fixed, and the scraper fixed by the sealing frame 15 is fixed and restricted. After the control of the second pneumatic cylinder 213 is operated and retracted, the sealing frame 15 and the scraper are released, and the scraper can be quickly replaced.
[0045] Then, the resin is poured into the resin material box 11 to control the light-curing 3D printer to work normally.
[0046] When the light-curing 3D printer is finished working, it is necessary to clean the inside of the resin material box 11 before refilling the resin box 11. First, the electric heating wire 110 is controlled to heat the scraper to make the scraper have a certain temperature, thereby reducing the resistance of the scraper to the resin on the inner wall of the resin material box 11. The resin material box 11 is cleaned thoroughly. The forward and reverse motor 121 in the driving component is controlled to work forward. The output end of the forward and reverse motor 121 fixedly installed outside the resin material box 11 is fixedly installed with the input end of the gear box 22. Both output ends of the gear box 22 are connected to the screw rod 23. The two screw rods 23 are fixedly connected, so they rotate synchronously. The two support frames 3 26 on the outside of the two screw rods 23 are simultaneously subjected to a force to move right, causing the two support frames 5 212 to move right. The sealing frame 15 clamped and contacted by the two support frames 6 215 and the scraper fixedly connected to the sealing frame 15 move right inside the resin material box 11, and the high-temperature scraper cleans the bottom wall, front wall and rear wall of the inner cavity of the resin material box 11; when the ends of the blade 12 and the blade 2 13 in the scraper contact the right wall of the inner cavity of the resin material box 11, the forward and reverse motor 1 21 stops working.
[0047] Subsequently, the pneumatic cylinder 1 211 is controlled to push the support frame 5 212 upward, and the sealing frame 15 and the scraper fixedly installed on the sealing frame 15 move upward, so that the blade 12 cleans the right wall of the inner cavity of the resin material box 11. After the blade 12 moves up a distance, the pneumatic cylinder 1 211 stops working.
[0048] Subsequently, the electromagnet 217 installed for rotation inside the control support frame seven 216 stops working, the fixation between the electromagnet 217 and the support frame seven 216 is removed, and the electromagnet 217 and the support frame six 215 are able to rotate, and then the forward and reverse motor two 222 is controlled to rotate forward for a period of time. Since a gear one 218 is fixedly installed on one side of the electromagnet 217, the gear one 218 is meshed with the gear two 219, and a transmission shaft 220 is fixedly installed inside the gear two 219, one end of the transmission shaft 220 is fixedly installed to the output end of the forward and reverse motor two 222, and the forward and reverse motor two 222 is fixedly connected to the support frame eight 229 fixedly installed on the adjacent support frame seven 216, and the support frame eight 229 fixed to the support frame seven 216 that cannot rotate cannot rotate, so the outer shell of the forward and reverse motor two 222 cannot rotate;
[0049] The two forward and reverse motors 222 are controlled to rotate forward, and the two transmission shafts 220 rotate. Under the transmission action of the gear 219 and the gear 1 218, the electromagnet 217 drives the support frame 6 215 to rotate. The plug-in plate 225 fixedly connected to the rotating support frame 6 215 is inserted into the plug-in slot 16 provided in the sealing frame 15. Therefore, the sealing frame 15 is subjected to the rotation force, and the heat conduction box 14 rotates.
[0050] During the operation of the forward and reverse motor 222, the forward and reverse motor 1 21 is controlled to reverse, so that the support frame 3 26 is subjected to a force to move to the left, the rotating support frame 6 215 moves to the left, and the sealing frame 15 moves to the left; at the same time, the pneumatic cylinder 1 211 contracts to drive the support frame 5 212 to move downward, the support frame 6 215 moves downward, and the sealing frame 15 moves downward; in summary, with the cooperation of the forward and reverse motor 1 21 and the pneumatic cylinder 1 211, the sealing frame 15 rotates with the line where the blade 12 and the inner wall of the resin material box 11 are located as the axis. On the premise that the end of the blade 12 remains in contact with the inner wall of the resin material box 11, the scraper as a whole rotates a certain angle, so that the end of the blade 12 is tilted. At this time, the scraper composed of the blade 12, the two blades 2 13, and the heat conduction box 14 is tilted as a whole, and the scraper has the effect of storing the resin under cleaning, avoiding the situation where the resin flows out and scatters after the scraper leaves the inside of the resin material box 11, thereby ensuring the effect of cleaning the inside of the resin material box 11.
[0051] When the above-mentioned scraper tilt adjustment work is completed, the pneumatic cylinder 211 is controlled to work and extend, so that the scraper completely leaves the inside of the resin material box 11. During this process, the blade 12 continues to contact the right wall of the inner cavity of the resin material box 11 to clean it, ensuring that the cleaning work inside the resin material box 11 is comprehensive and efficient, and avoiding the occurrence of cleaning dead corners inside the resin material box 11.
[0052] An L-shaped plate 3 is installed on one side of the resin material box 11. The inclination angle of the scraper is the same as the inclination angle of the L-shaped plate 3 close to the resin material box 11, so the control drive component and the control component work together to place the scraper on the L-shaped plate 3 and be supported by the L-shaped plate 3. Then the pneumatic cylinder 2 213 is controlled to shrink, and the support frame 6 215 moves away from the sealing frame 15. The scraper loses its fixation, so that the scraper temporarily stays inside the L-shaped plate 3 for heat dissipation, and the staff can directly push the L-shaped plate 3 to separate from the support frame 1 111, avoiding the possibility of the staff being injured by direct contact with the scraper, and directly remove the scraper from the resin material box 11, providing sufficient time and space for cleaning the scraper, and reducing the occurrence of resin contamination caused by unclean cleaning of the scraper.
[0053] Finally, the forward and reverse motor 1 21 is controlled to reverse, causing the support frame 5 212 and the support frame 6 215 to move right and reset. The pneumatic cylinder 1 211 is controlled to retract, causing the support frame 5 212 and the support frame 6 215 to move downward and reset. The electromagnet 217 is controlled to pause for a period of time. During this process, the forward and reverse motor 2 222 is controlled to reverse, causing the support frame 6 215 to rotate and reset, waiting for the installation of a new scraper. In addition, a brake 221 is sleeved on the outer side of the transmission shaft 220. The brake 221 is fixedly installed together with the adjacent support frame 8 229. After the forward and reverse motor 2 222 completes its operation, the brake 221 operates to limit the transmission shaft 220, and the gear 2 219 and the gear 1 218 meshing with the gear 219 are limited. The electromagnet 217 fixed to the gear 1 218 is limited and cannot rotate.
[0054] In addition, such as Figure 1 and Figure 5 As shown, a fixed horizontal plate 226 is fixedly installed on one side of the two support frames 3 26, and a clamping plate 228 is fixedly installed on one end of the pneumatic cylinder 3 227 fixedly installed on the top of the fixed horizontal plate 226. When the scraper tilt adjustment is completed, the pneumatic cylinder 3 227 can be controlled to work to push the clamping plate 228 to work. The two clamping plates 228 are clamped to both sides of the scraper, and the scraper position is fixed, which is convenient for the staff to collect the resin inside the scraper.
[0055] In addition, such as Figure 1 and Figure 2As shown, an elastic telescopic part 1 28 is fixedly installed between the support frame 4 27 and the support frame 3 26 on the same side, and an elastic telescopic part 29 is fixedly installed between the support frame 3 26 and the support frame 2 25 on the same side.
