[0001] The present invention relates to the technical field of feeding, and in particular to a special feeding mechanism for a ceramic 3D printer. Background Art

[0002] With the rapid development of science and technology, three-dimensional printing technology has shown great potential and application prospects in the manufacturing industry. As an important branch, ceramic 3D printing is gradually changing the face of the traditional ceramic manufacturing industry with its high efficiency, flexibility, precision and environmental protection. The feeding process of ceramic 3D printing is one of the key links in ceramic 3D printing technology. It is directly related to the continuity of printing and the quality of the final product. The feeding of ceramic 3D printing mainly involves the supply, transportation and precise control of ceramic materials to ensure that the required ceramic materials can be provided stably, continuously and accurately during the printing process.

[0012] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0013] 1. This special feeding mechanism for ceramic 3D printers drives the counterclockwise rotation of the gear ring meshing with the first gear, and drives the coverless column to rotate counterclockwise through the fixed connection between the gear ring and the coverless column. The ratchet gear ring connected to the coverless column rotates along with the counterclockwise rotation of the coverless column. The counterclockwise rotation of the ratchet gear ring generates resistance, so that the ratchet gear ring will drive the ratchet teeth to rotate together when rotating counterclockwise. The counterclockwise rotation of the ratchet teeth drives the rotation of the main rod. When the secondary rod rotates counterclockwise, the raised block fixedly connected to the secondary rod rotates counterclockwise, and the second disc seat rotates counterclockwise along with the raised block. The sliding groove on the second disc seat rotates counterclockwise, and the sliding rod is driven to rotate counterclockwise by the counterclockwise rotation of the sliding groove. The slider is fixedly connected under the triangular block, and the slider rotates counterclockwise. Through the track of the hexagonal track and the counterclockwise rotation of the triangular block, the six triangular slides are expanded outward, and the hose clamped by the triangular slide will be in a circulation state. The raw materials stored in the storage bin will flow into the barrel through the hose, and the raw materials in the hose will be sucked into the barrel through the upward suction of the piston. After the suction is completed, the first gear will rotate clockwise again, thereby completing the feeding action of the feeding component to extrude and suck the raw materials.

[0014] 2. The feeding mechanism dedicated to this ceramic 3D printer is connected by meshing of the first gear and the grooved rack. The first gear drives the movement of the grooved rack. The downward movement of the grooved rack drives the feeding rod of the feeding assembly to move downward. The tail of the feeding rod is fixedly connected with a piston. By setting the diameter of the piston to be the same as the inner wall diameter of the barrel, when the piston moves downward, it will push the raw material in the barrel into the nozzle, and finally extrude it through the nozzle onto the operating platform for 3D printing. This extrusion design sets the diameter of the piston to match the inner diameter of the barrel, and the raw material in the barrel can be completely squeezed out by the downward movement of the piston. The outer ring of the piston is in full contact with the inner wall of the barrel during the downward movement of the piston to scrape off the raw material on the inner wall of the barrel, thereby avoiding the adhesion of the raw material mud of ceramic printing to the inner wall of the barrel, which affects the printing effect and the storage capacity of raw materials.

[0015] 3. This kind of special feeding mechanism for ceramic 3D printer, when the gear ring rotates, the second gear meshing therewith rotates, the second gear is fixedly connected to the connecting rod, the connecting rod rotates driven by the second gear, the connecting rod passes through the third gear and is fixedly connected to the cutting knife, the cutting knife is fixedly connected to the stirring rod, the cutting knife and the stirring rod are driven to rotate by the rotation of the connecting rod, when the cutting knife and the stirring rod rotate, the raw materials stored in the storage bin can be stirred, the cutting knife has a sharp edge, and the raw materials can be cut while stirring, the raw material mud used for ceramic 3D printing is easy to agglomerate and clog after long-term accumulation, and the agglomerated raw materials can be dispersed by stirring and cutting with the stirring rod and the cutting knife, so that the material discharge is smoother during printing, and the printing quality is improved.

[0016] 4. This special feeding mechanism for ceramic 3D printers is connected with ratchet teeth by setting a spring, setting the ratchet teeth as an inclined surface, utilizing the contact between the inclined surface of the ratchet teeth and the ratchet gear ring, and generating resistance to the inclined surface of the ratchet teeth when the ratchet gear ring rotates clockwise and counterclockwise to drive the ratchet teeth to rotate, utilizing the elasticity of the spring, completing the transmission of the resistance on the ratchet teeth to the spring when the ratchet gear ring rotates clockwise, protecting the ratchet teeth while completing the opening and closing of the triangular slide in both clockwise and counterclockwise states, thereby controlling the output of raw materials, avoiding raw materials remaining in the triangular slide when the machine is not in use, and clogging the triangular slide when the raw materials remain for too long, resulting in the problem of rough quality of printed works. This design saves raw materials and avoids clogging.

[0017] 5. This special feeding mechanism for ceramic 3D printers is equipped with a stirring rod and a cutting knife, which are connected to the second gear. The second gear is meshed with the gear ring. No matter whether the second gear moves clockwise or counterclockwise, the gear ring will move in a circular motion. The circular motion of the gear ring drives the movement of the second gear, ensuring that the stirring rod and the cutting knife can rotate during the loading process or the printing process. The raw materials in the storage bin are always in a stirred state during operation, thereby ensuring the fineness of the extruded raw materials.

[0018] 6. This special feeding mechanism for ceramic 3D printers sets a hexagonal track on the first disc seat, and designs the shape of the hexagonal track to be compatible with the closed state of the triangular slide. A sliding rod is set on the triangular block, and the shape of the sliding rod is adapted to the slide groove, so that the six triangular slides can completely clamp the triangular slide in the closed state to ensure that the raw material in the hose does not flow out, and then the raw material in the triangular slide is released by unfolding the triangular slide.

Six sliding grooves 09 are opened on the second disc seat 07, and the sliding grooves 09 are adapted to the sliding rod 06.

[0043] Working principle:

[0044] The first step is to prepare the raw materials of the ceramics to be printed, and pour the raw materials into the stirring rod 1315. When using it for the first time, the raw materials must also be loaded into the feeding assembly 111, and the motor connected to the power arm 115 is turned on. The motor connected to the power arm 115 starts to supply energy to the power arm 115, and the power arm 115 starts to rotate. The power arm 115 rotates clockwise. When the power arm 115 rotates, the power arm 115 penetrates the connecting piece 114 and is connected to the first gear 116. The first gear 116 connected to the power arm 115 starts to rotate. After the first gear 116 rotates, the first gear 116 is meshed with the grooved rack 112 through the meshing connection of the first gear 116. The first gear 116 drives the movement of the grooved rack 112, and the grooved rack 112 starts to move downward. The grooved rack 112 is fixedly connected to the feeding assembly 111, and the downward movement of the grooved rack 112 drives the feeding assembly The loading rod 1111 of the component 111 moves downward, and the tail of the loading rod 1111 is fixedly connected with a piston 1112. By setting the diameter of the piston 1112 to be the same as the inner wall diameter of the barrel 1113, when the piston 1112 moves downward, the raw material in the barrel 1113 will be pushed into the nozzle 1114, and finally extruded through the nozzle 1114 onto the operating platform for 3D printing. This extrusion design sets the diameter of the piston 1112 to match the inner diameter of the barrel 1113, and the raw material in the barrel 1113 can be completely squeezed out by the downward movement of the piston 1112, and the outer ring of the piston 1112 is in full contact with the inner wall of the barrel 1113 during the downward movement of the piston 1112 to scrape off the raw material on the inner wall of the barrel 1113, thereby avoiding the adhesion of the raw material mud of ceramic printing to the inner wall of the barrel 1113, which affects the printing effect and the storage capacity of raw materials.

[0045] In the second step, the rotation of the first gear 116 also drives the rotation of the gear ring 121 meshing with the first gear 116. The gear ring 121 is fixedly connected to the uncovered column 123. When the gear ring 121 rotates, the uncovered column 123 rotates accordingly. Regardless of whether the gear ring 121 rotates counterclockwise or clockwise, the uncovered column 123 rotates counterclockwise or clockwise accordingly. In the first step, when the first gear 116 rotates clockwise, the gear ring 121 rotates clockwise, and the uncovered column 123 fixedly connected to the gear ring 121 rotates clockwise. A ratchet gear ring 122 is connected inside the uncovered column 123, and the ratchet gear ring 122 rotates clockwise along with the uncovered column 123. When the uncovered column 123 rotates clockwise, the inclined surface of each gear on the ratchet gear ring 122 applies pressure to the inclined surface of the ratchet tooth 1247. After receiving the pressure, the ratchet tooth 1247 moves in the direction of the spring 1246. The ratchet tooth 1247 generates a pressure on the spring 1246, causing the spring 1246 to contract, thereby making the ratchet tooth 1247 unable to block the ratchet gear ring 122, and the ratchet gear ring 122 can slide smoothly and continuously.

[0046] In the third step, when the gear ring 121 in the second step rotates, the second gear 1311 meshing therewith rotates, and the second gear 1311 is fixedly connected to the connecting rod 1312. The connecting rod 1312 rotates driven by the second gear 1311, and the connecting rod 1312 passes through the third gear 1313 and is fixedly connected to the cutting knife 1316. The cutting knife 1316 is fixedly connected to the stirring rod 1315, and the rotation of the connecting rod 1312 drives the rotation of the cutting knife 1316 and the stirring rod 1315. When the cutting knife 1316 and the stirring rod 1315 rotate, the raw materials stored in the storage bin 1314 can be stirred. The edge of the cutting knife 1316 is sharp, and the raw materials can be cut while stirring. The raw material mud used for ceramic 3D printing is easy to agglomerate and clog after long-term accumulation. The agglomerated raw materials can be dispersed by stirring and cutting the stirring rod 1315 and the cutting knife 1316, so that the material discharge during printing is smoother, thereby improving the printing quality.

[0047] In the fourth step, when the lower bottom surface of the piston 1112 in the first step is completely in contact with the upper bottom surface of the nozzle 1114, the raw material in the barrel 1113 is completely squeezed out and used up, and the first gear 116 starts to rotate counterclockwise. When the first gear 116 rotates counterclockwise, the connecting member 114 meshing with the first gear 116 will change the moving direction, and the connecting member 114 starts to move upward, and the grooved rack 112 fixedly connected to the connecting member 114 also moves upward with the upward movement of the connecting member 114. The upward movement of the grooved rack 112 drives the upward movement of the feeding assembly 111 fixedly connected to the grooved rack 112.

[0048] Step 5. In the initial stage of upward movement of the feeding assembly 111 in step 4, the counterclockwise rotation of the first gear 116 will drive the counterclockwise rotation of the gear ring 121 meshing with the first gear 116. The counterclockwise rotation of the gear ring 121 is transmitted to the uncovered column 123 through the fixed connection between the gear ring 121 and the uncovered column 123. When the uncovered column 123 rotates counterclockwise, the ratchet gear ring 122 connected to the uncovered column 123 rotates along with the counterclockwise rotation of the uncovered column 123. When the ratchet gear ring 122 rotates counterclockwise, the inclined surface of the ratchet tooth 1247 will generate resistance to the inclined surface of the gear in the ratchet gear ring 122. The resistance generated by 22 makes the ratchet gear ring 122 drive the ratchet teeth 1247 to rotate together when it rotates counterclockwise. The bottom surface of the ratchet teeth 1247 is fixedly connected to the rotating platform 1242. The rotating platform 1242 is fixedly connected to the main rod 1241, so that the counterclockwise rotation of the ratchet teeth 1247 drives the rotation of the main rod 1241. The main rod 1241 passes through the sleeve column 1243 and is fixedly connected to the auxiliary rod 1245, so that the counterclockwise rotation of the main rod 1241 is transmitted to the auxiliary rod 1245. When the auxiliary rod 1245 rotates counterclockwise, the raised block 010 fixedly connected to the auxiliary rod 1245 will rotate counterclockwise. 10 is fixedly connected to the second disc seat 07, and the second disc seat 07 rotates counterclockwise with the protruding block 010. A slide groove 09 is provided on the second disc seat 07, and the slide groove 09 rotates counterclockwise with the second disc seat 07. The sliding rod 06 fixedly connected to the triangular block 04 passes through the slide groove 09, and the slide rod 06 passing through the slide groove 09 is driven to rotate counterclockwise by the counterclockwise rotation of the slide groove 09. The slider 05 is fixedly connected to the lower part of the triangular block 04, and the slider 05 fixedly connected thereto is driven to rotate counterclockwise. The slider 05 is adapted to the hexagonal track 03 on the first disc seat 01, so that the slider 05 can be moved on the hexagonal track 03. Sliding, through the counterclockwise rotation of the track of the hexagonal track 03 and the triangular block 04, the six triangular slides 1322 are expanded outward, and when the six triangular slides 1322 are expanded, the hose 1332 clamped by the triangular slide 1322 will be in a flow state, and the raw materials stored in the storage bin 1314 will flow into the barrel 1113 through the hose 1332, and the raw materials in the hose 1332 will be sucked into the barrel 1113 through the upward suction of the piston 1112. After the suction is completed, the first gear 116 will rotate clockwise again, and the above movement is repeated to perform the feeding action of extruding and sucking the raw materials for the feeding component 111.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
