[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1.

By the mutual cooperation of the first half gear on the first rotating shaft, the second half gear on the second rotating shaft, the fifth gear on the third rotating shaft, etc., the screening plate is driven to move reciprocally left and right. This unique transmission method enables the screening plate to efficiently screen the crushed materials, ensuring the uniformity of the particle size of the recycled materials, improving the quality of the recycled materials, being beneficial for subsequent reuse in the 3D printer body, and enhancing the quality stability of the printed products.

[0017] 2. The 3D printer with a printing material recycling device drives the first crushing roller by a first motor. Through the meshing of the first gear and the second gear, the second crushing roller is driven to rotate in the opposite direction.

[0018] 3. In the 3D printer with a printing material recycling device, in the material pushing mechanism, a second motor drives a lead screw to rotate. The moving frame moves steadily back and forth under the action of the lead screw and the limiting rod. Through the connection of the articulated frame, the articulated rod with the push rod and the push plate, the items or remaining materials that have completed printing on the base of the 3D printer body can be accurately pushed to the designated position, facilitating subsequent collection or processing, greatly improving the operation convenience, reducing the workload of manual operation, and at the same time reducing the risk of item damage caused by manual operation.

[0019] 4. The 3D printer with a printing material recycling device has a receiving frame of the collection mechanism that can be easily pulled out and pushed into the box body through a handle. The sliding plate can achieve automatic reset through the cooperation of the guide rod and the spring in the rectangular frame. When the receiving frame is pushed into the box body, the limiting block slides in the limiting groove, and the sliding plate automatically pops out under the action of the spring to limit the receiving frame and prevent it from accidentally sliding out; when the receiving frame needs to be taken out, press the sliding plate, and the limiting block disengages from the limiting groove, then the receiving frame can be easily taken out. This design facilitates the collection and cleaning of the recycled materials, improving the convenience and efficiency of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Refer toFigures 9 - 11 , and on the basis of the first embodiment, a collection mechanism 6 is further obtained.

[0034] Furthermore, the collection mechanism 6 includes a material receiving frame 61. A handle 62 is fixedly connected to the front of the material receiving frame 61. Rectangular frames 63 are fixedly connected to the left and right sides of the front of the box body 1 at the top of the material receiving frame 61. A slide plate 65 is slidably connected to the front of the inner wall of the rectangular frame 63. Second fixing plates 66 are fixedly connected to the upper and lower sides of the front of the rectangular frame. A guide rod 64 is fixedly connected to the back of the second fixing plate 66. A spring 67 is sleeved on the surface of the guide rod 64 between the slide plate 65 and the second fixing plate 66. A connecting block 68 is fixedly connected to the bottom of the slide plate 65. A fourth rotating shaft 69 is rotatably connected to the back of the connecting block 68. A limiting block 611 is fixedly connected to the rear end of the fourth rotating shaft 69. Limiting grooves 612 corresponding to the limiting block 611 are formed in the left and right sides of the top of the front of the material receiving frame 61.

[0035] Furthermore, a groove matching the material receiving frame 61 is formed in the bottom of the front of the box body 1, and the surface of the material receiving frame 61 penetrates through and is slidably connected to the inside of the groove in the front-back direction. Through holes matching the guide rod 64 are formed in the upper and lower sides of the front of the slide plate 65, and the slide rod is slidably connected to the surface of the guide rod 64 through the through holes. The rear end of the guide rod 64 is fixedly connected to the front of the box body 1. The rear end of the spring 67 is fixedly connected to the front of the slide plate 65, and the front end of the spring 67 is fixedly connected to the back of the second fixing plate 66.

[0036] In the actual operation process, when this device is in use, the second motor 53 starts, and its output end drives the lead screw 52 to rotate. The lead screw 52 is threadedly connected to the moving frame 54, and a hole matching the limiting rod 55 is provided near the left side of the bottom of the front surface of the moving frame 54. Under the limiting action of the limiting rod 55, the moving frame 54 can only move back and forth along with the rotation of the lead screw 52. An articulated rod 57 is articulated in the articulated frame 56 at the top of the moving frame 54, and the other end of the articulated rod 57 is articulated with a push rod 58. The right end of the push rod 58 is fixedly connected to a push plate 59. When the moving frame 54 moves back and forth, through the transmission of the articulated frame 56 and the articulated rod 57, the push rod 58 moves left and right in the sliding frame 511, thereby driving the push plate 59 to push the remaining material on the base of the 3D printer body 3 onto the inclined plate 417, and the inclined plate 417 drops the remaining material into the box body 1. The first motor 412 starts, and its output end drives the first crushing roller 413 to rotate. Since a first gear 415 is fixed near the front end of the back surface of the first crushing roller 413, and the first gear 415 meshes with a second gear 416 on the surface near the front end of the second crushing roller 414, the rotation of the first crushing roller 413 will drive the second crushing roller 414 to rotate in the reverse direction through gear transmission. The inclined plate 417 at the top right of the inner wall of the box body 1 guides the printing material between the first crushing roller 413 and the second crushing roller 414. The reverse rotation of the first crushing roller 413 and the second crushing roller 414 forms extrusion and tearing of the material, thereby crushing the printing material into smaller particles to prepare for subsequent screening; A first pulley 427 is fixed near the front end of the surface of the second crushing roller 414 and is connected to a second pulley 428 in the middle of the surface of the first rotating shaft 426 through a belt 429. Therefore, when the second crushing roller 414 rotates, it will drive the first rotating shaft 426 to rotate through the transmission of the belt 429. A third gear 4211 near the rear end of the surface of the first rotating shaft 426 meshes with a fourth gear 4213 near the rear end of the surface of the second rotating shaft 4212, so that when the first rotating shaft 426 rotates, it drives the second rotating shaft 4212 to rotate. A first half gear 4214 near the front end of the surface of the first rotating shaft 426 and a second half gear 4215 near the front end of the surface of the second rotating shaft 4212 will alternately mesh with a fifth gear 4217 near the front end of the surface of the third rotating shaft 4216. When the first half gear 4214 meshes with the fifth gear 4217, it drives the fifth gear 4217 to rotate. The fifth gear 4217 also meshes with a rack 4219 on the top of a fixing block 4218 on the front surface of the slider 422, thereby pushing the slider 422 to move to one side in the chute 421 and driving the screening plate 423 to move. When the second half gear 4215 meshes with the fifth gear 4217, the fifth gear 4217 rotates in the reverse direction, driving the screening plate 423 to move to the other side. In this way, a cyclic movement is achieved, realizing the left-right reciprocating movement of the screening plate 423 on the front surface of the box body 1 to screen the crushed materials. The materials with qualified particle sizes enter the interior of the box body 1 through the screening plate 423 for further processing, and the unqualified ones are pushed out from the right side of the screening plate 423 and can be crushed again; When the screened qualified materials fall into the material collection frame 61 and it is necessary to take out the material collection frame 61, hold the handle 62 by hand and pull the sliding plate 65. The sliding plate 65 is connected to the fourth rotating shaft 69 and the limiting block 611 through the connecting block 68. When pulling the sliding plate 65, the sliding plate 65 slides backward in the rectangular frame 63 against the elastic force of the spring 67, so that the limiting block 611 disengages from the limiting grooves 612 on the left and right sides of the top of the front surface of the material collection frame 61. Then rotate the limiting block 611 so that the limiting block 611 moves away from the front of the limiting groove 612. At this time, the material collection frame 61 can be pulled out from the slot opened at the bottom of the front surface of the box body 1. When it is necessary to put the material collection frame 61 back into the box body 1, push the material collection frame 61 into the slot at the bottom of the front surface of the box body 1, release the sliding plate 65, and under the action of the elastic force of the spring 67, the sliding plate 65 slides forward, and the limiting block 611 slides back into the limiting groove 612 on the top of the front surface of the material collection frame 61 to limit the material collection frame 61 and prevent it from sliding out accidentally, realizing the stable collection of the recycled materials.
