Description

Technical Field

[0001] The present invention relates to the technical field of cleaning, and specifically to a scraper device for a stereolithography 3D printer that can be quickly replaced. Background Art

[0002] When replacing the resin in a stereolithography 3D printer, the old resin needs to be first cleared out of the material box, and then new resin is added. The resin is liquid and has a certain viscosity, making it difficult to completely clear the resin from the material box. Therefore, there are material boxes with resin cleaning functions on the market. For example, the existing patent document with the application number 202221667589.7 provides a scraper device for a stereolithography 3D printer, belonging to the technical field of stereolithography 3D printers. It includes an installation box and a connection seat. A servo motor is installed on one side of the installation box. Two lead screws are installed inside the installation box and the connection seat. A threaded block is sleeved on the outer surface of the lead screw. An installation part is arranged at the bottom of the threaded block, and a scraper is arranged at the bottom of the installation part. Through the setting of the lead screw, servo motor, threaded block, heating wire, rotating wheel, transmission belt, spring, and installation part, the rotation of the servo motor causes the lead screw to rotate, and then the rotating wheel and the transmission belt cooperate.

[0003] Taking the scraper device provided inside the material box of the above stereolithography 3D printer as an example, although a scraper device is provided to clean the resin inside the material box, as the use time of the scraper increases, the resin on the outer side of the scraper increases, which will cause the scraper to lose its function. However, the scraper needs to be installed on the displacement control structure, resulting in difficult disassembly and replacement of the scraper and affecting the use of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a scraper device for a stereolithography 3D printer that can be quickly replaced to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A scraper device for a stereolithography 3D printer that can be quickly replaced, including a material box structure of a stereolithography 3D printer. The material box structure of the stereolithography 3D printer includes a resin material box. A heat conduction box is arranged inside the resin material box. Two blades two are fixedly installed on both sides of the heat conduction box. A blade one is fixedly installed at the bottom of one side of the blade two. A sealing frame is fixedly installed on the top of the heat conduction box. A tool control structure is arranged outside the sealing frame. The tool control structure includes a driving component installed outside the material box structure of the stereolithography 3D printer, two support frames three driven by the driving component, two control components arranged on the two support frames three, and a support frame six arranged at one end of the two control components close to the resin material box. A power socket and a plug board are arranged between the two support frames six and both ends of the sealing frame respectively.

[0006] Preferably, sliding grooves are formed on both sides of the top of the resin material tank, and limiting blocks are arranged inside the two sliding grooves. The limiting blocks are fixedly installed at the bottom of the sealing frame.

[0007] Preferably, insertion slots are formed on both sides of the sealing frame. A power plug is arranged inside the insertion slot close to the power socket. The power plug is fixedly connected to the sealing frame. An electric heating wire is fixedly installed inside the heat conduction box. When the electric heating wire works, it heats the scraper, so that the scraper has a certain temperature, reducing the resistance suffered by the scraper when cleaning the resin on the inner wall of the resin material tank.

[0008] Preferably, a first support frame is fixedly installed at one end of the resin material tank away from the heat conduction box. An L-shaped plate member is sleeved outside the first support frame. The control driving component and the control component cooperate to work, and the scraper is placed on the L-shaped plate member and supported by the L-shaped plate member.

[0009] Preferably, the driving component includes a forward and reverse motor I and a gear box fixedly installed outside the resin material tank. The output end of the forward and reverse motor I is fixedly installed with the input end of the gear box. Screws are fixedly installed at both output ends of the gear box. The third support frame is sleeved outside the adjacent screw through a nut pair. A fourth support frame is rotatably sleeved outside the screw. One end of the screw away from the gear box is rotatably connected to a second support frame. Both the second support frame and the fourth support frame are fixedly connected to the resin material tank. A guide rod is fixedly installed between the second support frame and the fourth support frame. The guide rod penetrates through the third support frame. Under the limitation of the guide rod, the third support frame can only move horizontally left and right, ensuring the stability of the working movement of the third support frame.

[0010] Preferably, both of the control components include two first telescopic rods fixedly inserted on the third support frame, a fifth support frame fixedly installed between the two first telescopic rods, a second air cylinder and four second telescopic rods fixedly inserted on the fifth support frame. The first telescopic rods that can be telescopic limit the fifth support frame, so that the fifth support frame can only move up and down. By controlling the second air cylinder to work to extend or contract, the up and down position of the fifth support frame can be controlled. A first air cylinder is fixedly installed on one side of the third support frame. The top end of the first air cylinder is fixedly connected to the fifth support frame.

[0011] Preferably, a support frame seven is fixedly installed between the piston ends of the four telescopic rods on the same side. Electromagnets are rotatably installed inside both support frames seven. The electromagnets are fixedly connected to the adjacent support frames six. The electromagnets are rotatably installed outside the piston ends of the adjacent pneumatic cylinders two. A gear one is fixedly installed on one side of each of the two electromagnets. The gear one meshes with a gear two. A transmission shaft is fixedly installed inside each of the two gear twos. Under the cooperation of the forward and reverse motor one and the pneumatic cylinder one, the sealing frame rotates with the line where the position of the blade one in contact with the inner wall of the resin tank is located as the axis. The overall scraper composed of the blade one, the two blade twos, and the heat conduction box is inclined. The scraper plays a role in storing the resin cleaned. A brake is sleeved outside each of the two transmission shafts. The brake works to limit the transmission shaft, and the gear two and the gear one meshed with the gear two are limited. A support frame eight is fixedly installed between the brake and the adjacent support frame seven.

[0012] Preferably, a forward and reverse motor two is fixedly installed at one end of each of the two transmission shafts. The outer shell of the forward and reverse motor two is fixedly connected to the adjacent support frame eight.

[0013] Preferably, a fixed horizontal plate is fixedly installed on one side of the support frame three. A pneumatic cylinder three is fixedly installed on the top of the fixed horizontal plate. A clamping plate is fixedly installed at one end of the pneumatic cylinder three. By controlling the pneumatic cylinder three to work and push the clamping plate to work, the two clamping plates clamp both sides of the scraper, and the position of the scraper is fixed.

[0014] Preferably, an elastic telescopic member one is fixedly installed between the support frame four and the support frame three on the same side, and an elastic telescopic member two is fixedly installed between the support frame three and the support frame two on the same side. The elastic telescopic member one and the elastic telescopic member two protect the lead screw and the guide rod, preventing resin from dripping onto the lead screw and affecting the accuracy of the position control of the support frame three. Compared with the prior art, the beneficial effects of the present invention are: 1. In this application, the plug-in board is inserted into the plug-in slot far from the power plug. Under the action of the two support frames six, the power socket, and the plug-in board, the sealing frame is clamped and fixed, and the scraper fixed by the sealing frame is fixed and restricted. After controlling the pneumatic cylinder two to work and contract, the sealing frame and the scraper can lose their fixation, and the scraper can be quickly replaced.

[0015] 2. In this application, under the cooperation of the forward and reverse motor 1 and the pneumatic cylinder 1, the sealing frame rotates around the line where the contact position between the blade 1 and the inner wall of the resin tank is located as the axis. On the premise that the end of the blade remains in contact with the inner wall of the resin tank, the entire scraper rotates by a certain angle so that the end of the blade is inclined. At this time, the entire scraper composed of the blade 1, the two blades 2, and the heat conduction box is inclined. The scraper plays a role in storing the resin after cleaning, avoiding the situation where the resin flows out and scatters after the scraper leaves the inside of the resin tank, ensuring the cleaning effect of the inside of the resin tank, and enabling the scraper to completely leave the inside of the resin tank. During this process, the blade 1 continues to contact the right wall of the inner cavity of the resin tank to clean it, ensuring the comprehensive and efficient progress of the cleaning work inside the resin tank and avoiding the situation of cleaning dead corners inside the resin tank.

[0016] 3. In this application, the inclination angle of the scraper is the same as the inclination angle of the L-shaped plate near the resin tank end. Therefore, the control drive assembly and the control assembly cooperate to work. The scraper is placed on the L-shaped plate and supported by the L-shaped plate. The pneumatic cylinder 2 is controlled to contract, and the support frame 6 moves away from the sealing frame. The scraper loses its fixation, so that the scraper stays temporarily inside the L-shaped plate for heat dissipation. Moreover, the staff can directly push the L-shaped plate to separate it from the support frame 1, avoiding the possibility of the staff being injured by directly contacting the scraper, and directly disassembling the scraper from the inside of the resin tank, providing sufficient time and space for the cleaning of the scraper and reducing the resin pollution caused by unclean cleaning on the scraper.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Embodiment: As Figures 1 - 13 shown, the present invention provides a technical solution for a scraping knife 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-conducting box 14 is arranged inside the resin material box 11. Blade 2s 13 are fixedly installed on both sides of the heat-conducting box 14. Blade 1 12 is fixedly installed at the bottom of one side of the blade 2 13. A sealing frame 15 is fixedly installed on the top of the heat-conducting box 14. A tool control structure 2 is arranged outside the sealing frame 15. The tool control structure 2 includes a driving component installed outside the light-curing 3D printer material box structure 1, two support frames 3 26 driven by the driving component, two control components arranged on the two support frames 3 26, and a support frame 6 215 arranged at one end of the two control components close to the resin material box 11. A power socket 224 and an insertion board 225 are arranged between the two support frames 6 215 and both ends of the sealing frame 15 respectively.

[0021] Specifically, on both sides of the heat conduction box 14 arranged inside the resin material box 11, second blades 13 are fixedly installed. The two second blades 13 respectively clean the inner walls of the front side and the rear side of the resin material box 11. At the bottom of one side of the heat conduction box 14, a first blade 12 is fixedly installed. The first blade 12 cleans the bottom wall of the inner cavity of the resin material box 11. At the top of the heat conduction box 14, a sealing frame 15 is fixedly installed. The length of the sealing frame 15 is longer than the distance between the inner wall of the front side and the inner wall of the rear side of the resin material box 11. The sealing frame 15 supports and limits the scraper composed of the heat conduction box 14, the two second blades 13 and the first blade 12. On both sides of the top of the resin material box 11, sliding grooves 19 are respectively opened. Two limiting blocks 18 arranged inside the two sliding grooves 19 are fixedly installed at the bottom of the sealing frame 15. Under the limitation and guidance of the two limiting blocks 18 and the two sliding grooves 19, the sealing frame 15 and the scraper installed on the sealing frame 15 perform horizontal left-right movement, avoiding unnecessary abrasion between the scraper and the inner wall of the resin material box 11.

[0022] Specifically, at one end of the resin material box 11 far away from the heat conduction box 14, a first support frame 111 is fixedly installed. An L-shaped plate member 3 is sleeved outside the first support frame 111. The L-shaped plate member 3 can leave from the outside of the first support frame 111. The L-shaped plate member 3 in the shape of an L is used to support the scraper leaving the inside of the resin material box 11, facilitating the manual holding and operation of the scraper by the staff and reducing the possibility of the staff being injured by the scraper.

[0023] Specifically, insertion slots 16 are respectively opened on both sides of the sealing frame 15. Inside the insertion slot 16 close to the power socket 224, a power plug 17 is arranged. The power plug 17 fixedly connected to the sealing frame 15 is electrically connected to the heating wire 110 fixedly installed inside the heat conduction box 14. When the heating wire 110 works, it heats the liquid inside the heat conduction box 14, causing the temperature of the heat conduction box 14, the second blade 13 and the first blade 12 made of materials with good heat conductivity to rise.

[0024] Specifically, on both output ends of the gear box 22 in the driving assembly, lead screws 23 are fixedly installed. The third support frame 26 is sleeved outside the adjacent lead screw 23 through a nut pair. And a fourth support frame 27 is rotatably sleeved outside the lead screw 23. One end of the lead screw 23 far away from the gear box 22 is rotatably connected to a second support frame 25. Both the second support frame 25 and the fourth support frame 27 are fixedly connected to the resin material box 11, enabling the lead screw 23 to be supported and perform self-rotation. And a guide rod 24 is fixedly installed between the second support frame 25 and the fourth support frame 27. The guide rod 24 penetrates through the third support frame 26 to limit the third support frame 26. Under the limitation of the guide rod 24, the third support frame 26 can only perform horizontal left-right movement, ensuring the stability of the working movement of the third support frame 26.

[0025] Specifically, both of the first telescopic rods 210 in the control component are fixedly inserted into the third support frame 26. A fifth support frame 212 is fixedly installed between the two first telescopic rods 210. The first telescopic rods 210 that can be telescoped limit the fifth support frame 212, enabling the fifth support frame 212 to only move up and down. The top end of the first pneumatic cylinder 211 fixedly installed on one side of the third support frame 26 is fixedly connected to the fifth support frame 212. By controlling the first pneumatic cylinder 211 to work in extension or contraction, the up and down position of the fifth support frame 212 can be controlled. And a second pneumatic cylinder 213 and four second telescopic rods 214 are horizontally and fixedly inserted into the fifth support frame 212. A seventh support frame 216 is fixedly installed between the four second telescopic rods 214 in one control component. The seventh support frame 216 cannot rotate relative to one side of the fifth support frame 212. The electromagnet 217 rotatably installed inside the seventh support frame 216 is fixedly connected to the adjacent sixth support frame 215. The electromagnet 217 is rotatably installed outside the piston end of the adjacent second pneumatic cylinder 213. By controlling the second pneumatic cylinder 213 to work in extension or contraction, the front and back positions of the electromagnet 217 and the sixth support frame 215 can be controlled, and the rotation of the electromagnet 217 will not affect the normal operation of the second pneumatic cylinder 213. Under normal conditions, the electromagnet 217 is in a working state. The electromagnet 217 is adsorbed and fixed to the iron seventh support frame 216 by magnetic force. At this time, the seventh support frame 216 cannot rotate, the electromagnet 217 cannot rotate, the sixth support frame 215 fixedly connected to the seventh support frame 216 cannot rotate, and the relative position between the sixth support frame 215 and the fifth support frame 212 cannot change.

[0026] In this application, the tool control structure 2 installed outside the resin material box 11 meets the working requirements such as the clamping and fixing of the scraper, the translational drive of the scraper, and the rotation of the scraper. The specific working method is as follows: Place the scraper into the resin material box 11, and control the smooth surface of the heat conduction box 14 without installed structure to fit against the left inner wall of the resin material box 11, so that the scraper enters the working position. Subsequently, two pneumatic cylinders 211 in the two control components work and extend, two support frames 212 move upward, the support frame 212 drives the support frame 215 upward through the pneumatic cylinder 213, and the two support frames 215 move to both ends of the sealing frame 15. The power socket 224 fixedly installed on one of the support frames 215 and the plug board 225 fixedly installed on the other support frame 215 are aligned with the two plug slots 16. Subsequently, control the two pneumatic cylinders 213 to work and extend, so that the two support frames 215 abut against the sealing frame 15, and a power plug 17 is arranged inside the plug slot 16 close to the power socket 224, so that the power socket 224 is sleeved outside the power plug 17. The power socket 224 is used to connect wires, so that the heating wire 110 is powered on 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 controlling the pneumatic cylinder 213 to work and contract, the sealing frame 15 and the scraper can be unfixed, and the scraper can be quickly replaced.

[0027] Subsequently, normally pour resin into the resin tank 11 and control the operation of the stereolithography 3D printer.

[0028] When the stereolithography 3D printer finishes working and needs to clean the inside of the resin tank 11 before refilling the resin tank 11, first control the heating wire 110 to work to heat the scraper, so that the scraper has a certain temperature, reduce the resistance suffered by the scraper when cleaning the resin on the inner wall of the resin tank 11, and ensure that the inside of the resin tank 11 is cleaned thoroughly. Control the forward and reverse motor 21 in the drive assembly to rotate forward. The output end of the forward and reverse motor 21 fixedly installed outside the resin tank 11 is fixedly installed with the input end of the gear box 22. Both output ends of the gear box 22 are fixedly connected with the lead screws 23. Therefore, the two lead screws 23 rotate synchronously. The two support frames 26 sleeved outside the two lead screws 23 through the nut pair are synchronously subjected to the force of moving rightward, so that the two support frames 212 move rightward. The sealing frame 15 clamped and abutted by the two support frames 215 and the scraper fixedly connected to the sealing frame 15 move rightward inside the resin tank 11, and the high-temperature scraper cleans the bottom wall, the front wall and the rear wall of the inner cavity of the resin tank 11. When the ends of the blade 12 and the blade 13 in the scraper contact the right inner wall of the resin tank 11, the forward and reverse motor 21 pauses working.

[0029] Subsequently, control the pneumatic cylinder 211 to work to push the support frame 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 inner wall of the resin tank 11. After the blade 12 moves upward for a certain distance, the pneumatic cylinder 211 pauses working.

[0030] Subsequently, the electromagnet 217 rotatably installed inside the seventh support frame 216 stops working, and the fixation between the electromagnet 217 and the seventh support frame 216 is removed. The electromagnet 217 and the sixth support frame 215 can rotate. Then, the forward and reverse motor two 222 is controlled to rotate forward for a period of time. Since a first gear 218 is fixedly installed on one side of the electromagnet 217, the first gear 218 meshes with a second gear 219, and a transmission shaft 220 is fixedly installed inside the second gear 219. One end of the transmission shaft 220 is fixedly installed with the output end of the forward and reverse motor two 222. The forward and reverse motor two 222 is fixedly connected to the eighth support frame 229 fixedly installed on the adjacent seventh support frame 216. The eighth support frame 229 fixedly installed on the non-rotatable seventh support frame 216 cannot rotate, so the housing of the forward and reverse motor two 222 cannot rotate; Control the two forward and reverse motors two 222 to rotate forward. The two transmission shafts 220 rotate. Under the transmission action of the second gear 219 and the first gear 218, the electromagnet 217 drives the sixth support frame 215 to rotate. And the insertion plate 225 fixedly connected to the rotating sixth support frame 215 is inserted into the insertion slot 16 opened in the sealing frame 15. Therefore, the sealing frame 15 receives a rotating force and the heat conduction box 14 rotates; During the operation of the forward and reverse motor two 222, control the forward and reverse motor one 21 to rotate in reverse, so that the third support frame 26 receives a leftward force, and the rotating sixth support frame 215 moves leftward, and the sealing frame 15 moves leftward; at the same time, the first air cylinder 211 contracts to drive the fifth support frame 212 to move downward, the sixth support frame 215 moves downward, and the sealing frame 15 moves downward; in summary, under the cooperation of the forward and reverse motor one 21 and the first air cylinder 211, the sealing frame 15 rotates with the line where the contact position between the first blade 12 and the inner wall of the resin tank 11 is located as the axis. On the premise that the end of the first blade 12 remains in contact with the inner wall of the resin tank 11, the entire scraper rotates by a certain angle, making the end of the first blade 12 inclined. At this time, the entire scraper composed of the first blade 12, the two second blades 13, and the heat conduction box 14 is inclined. The scraper plays a role in storing the resin cleaned, avoiding the situation where the resin flows out and scatters after the scraper leaves the inside of the resin tank 11, and ensuring the cleaning effect of the inside of the resin tank 11.

[0031] After the above-mentioned inclination adjustment of the scraper is completed, control the first air cylinder 211 to extend, so that the scraper completely leaves the inside of the resin tank 11. During this process, the first blade 12 continues to contact the right inner wall of the resin tank 11 to clean it, ensuring the comprehensive and efficient cleaning work of the inside of the resin tank 11 and avoiding the situation of cleaning dead corners inside the resin tank 11.

[0032] An L-shaped plate member 3 is installed on one side of the resin tank 11. The inclination angle of the scraper is the same as the inclination angle of the end of the L-shaped plate member 3 close to the resin tank 11. Therefore, the control drive assembly and the control assembly cooperate to work. The scraper is placed on the L-shaped plate member 3 and supported by the L-shaped plate member 3. Subsequently, the second pneumatic cylinder 213 contracts, and the sixth support frame 215 moves away from the sealing frame 15. The scraper loses its fixation, so that the scraper stays temporarily inside the L-shaped plate member 3 for heat dissipation. And the staff can directly push the L-shaped plate member 3 to separate from the first support frame 111, avoiding the possibility of the staff being injured by directly contacting the scraper, and directly disassembling the scraper from the inside of the resin tank 11, providing sufficient time and space for the cleaning of the scraper, and reducing the occurrence of resin contamination caused by unclean cleaning of the scraper.

[0033] Finally, control the first forward and reverse motor 21 to reverse and work, so that the fifth support frame 212 and the sixth support frame 215 move rightward to reset. Control the first pneumatic cylinder 211 to work and contract, so that the fifth support frame 212 and the sixth support frame 215 move downward to reset. Control the electromagnet 217 to pause working for a period of time. During this process, control the second forward and reverse motor 222 to reverse and work, so that the sixth support frame 215 rotates to reset, waiting for the installation of a new scraper. And a brake 221 is sleeved outside the transmission shaft 220. The brake 221 is fixedly installed together with the adjacent eighth support frame 229. After the second forward and reverse motor 222 finishes working, the brake 221 works to limit the transmission shaft 220, and the second gear 219 and the first gear 218 meshed with the second gear 219 are limited. The electromagnet 217 fixed to the first gear 218 is limited and cannot rotate.

[0034] In addition, as Figure 1 and Figure 5 shown, fixed cross plates 226 are fixedly installed on one side of the two third support frames 26. One end of the third pneumatic cylinder 227 fixedly installed on the top of the fixed cross plate 226 is fixedly installed with a clamping plate 228. After the inclination adjustment of the scraper is completed, the third pneumatic cylinder 227 can be controlled to work to push the clamping plate 228 to work. The two clamping plates 228 clamp on both sides of the scraper, and the position of the scraper is fixed, which is convenient for the staff to collect the resin inside the scraper.

[0035] In addition, as Figure 1 and Figure 2 shown, an elastic telescopic member 28 is fixedly installed between the fourth support frame 27 and the third support frame 26 on the same side, and an elastic telescopic member 29 is fixedly installed between the third support frame 26 and the second support frame 25 on the same side. The elastic telescopic members 28 and 29 that can perform elastic telescoping will not affect the movement of the third support frame 26, and the elastic telescopic members 28 and 29 protect the lead screw 23 and the guide rod 24, avoiding resin dripping onto the lead screw 23 and affecting the working accuracy of the position of the third support frame 26.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
