Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing material output mechanism. Background Technology

[0002] As a rapid prototyping technology, 3D printing uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects by printing layer by layer. In the 3D printing process, the material output mechanism plays a key role, and its performance directly affects the printing quality and efficiency. Currently, existing 3D printing ejection mechanisms have some shortcomings. The nozzle, as a crucial component, is prone to clogging during prolonged use. Once clogged, it needs to be disassembled and cleared. However, traditional ejection mechanism nozzles are complex to connect with other components, making disassembly cumbersome, time-consuming, and labor-intensive, severely impacting work efficiency. For example, some ejection mechanism nozzles are secured with multiple screws, requiring individual unscrewing during disassembly, and precise adjustment of position and tightening force during reinstallation, making the process inconvenient.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] For examples, please refer to Figures 1 to 5This utility model provides a technical solution: a 3D printing material output mechanism, including a fixed box 101. A clamping assembly is provided on the lower side of the interior of the fixed box 101. The clamping assembly includes a rectangular plate 104, a bidirectional screw 105, and two clamping plates 108. The rectangular plate 104 is fixedly installed on the inner wall of the fixed box 101, and the bidirectional screw 105 is rotatably installed on one side of the rectangular plate 104. A conveying assembly is provided on the upper side of the clamping assembly for stable conveying of consumables. The two clamping plates 108 are respectively threaded onto both sides of the bidirectional screw 105. A knob 106 is fixedly connected to one end of the bidirectional screw 105. The clamping assembly includes a driving gear 201, a driven gear 202, and two conveying plates 203. The driving gear 201 and the driven gear 202 are both rotatably installed on... Inside the fixed box 101, two conveyor plates 203 are respectively fixedly installed on one side of the driving gear 201 and the driven gear 202. A handle 204 is rotatably installed on one side of one of the conveyor plates 203. The handle 204 is L-shaped and is rotatably installed inside the fixed box 101. A support member 206 is fixedly installed inside the fixed box 101. One end of the support member 206 is connected to a spring 207. The other end of the spring 207 is fixedly connected to the other end of the handle 204. A slot 205 is opened inside the handle 204. A slot 110 is provided on the lower side of the fixed box 101. A buffer pad 109 is fixedly installed on one end of each of the two clamping plates 108. A cover plate 102 is fixedly installed on one side of the fixed box 101. A rubber pad 103 is provided on one side of the cover plate 102.

[0024] In this embodiment, the cover plate 102 and the fixing box 101 are fixedly connected by a snap fastener. A rubber pad 103 is installed on one side of the cover plate 102. When the cover plate 102 is installed, the rubber pad 103 can fit tightly against the nozzle, thereby providing a certain buffer for the nozzle. After opening the cover plate 102, the knob 106 at one end of the bidirectional screw 105 is manually rotated. Driven by the knob 106, the bidirectional screw 105 is rotated. The two clamping plates 108 are respectively threaded onto the bidirectional screw 105. On both sides, the bottoms of the two clamping plates 108 are in contact with the rectangular plate 104. A support plate 107 is installed on one side of the rectangular plate 104. A bidirectional screw 105 is located on the underside of the support plate 107. A slot 110 is provided at the bottom of the fixing box 101. The nozzle is engaged in the slot 110 and in contact with the support plate 107. The buffer pad 109 at one end of the two clamping plates 108 is used to stably clamp the nozzle. At this time, the distance between the two clamping plates 108 gradually increases as the bidirectional screw 105 rotates. The nozzle is then released from its fixation. A tool is used to remove the nozzle along the slot 110. When using the device, the consumable is inserted through the slot 205 between the two conveyor plates 203. Each conveyor plate 203 has an arc-shaped groove in the middle. The two conveyor plates 203 are fixedly connected to the drive gear 201 and the driven gear 202, respectively. One side of the drive gear 201 is fixedly connected to the motor drive end, thus rotating under the drive of the motor. Through the meshing of the conveyor plates 203 and the driven gear 202, the two conveyor plates 203 rotate towards each other, thereby driving the consumable between the two conveyor plates 203 to move downwards. When installing the consumable, one end of the handle 204 is manually pressed. A spring 207 is connected between one end of the handle 204 and the support member 206. The handle 204 is L-shaped. Rotation of the handle 204 causes the other end to move the driven gear 202 away from the drive gear 201, allowing the consumable to be inserted between the two conveyor plates 203.

[0025] Working principle: The cover plate 102 and the fixing box 101 are fixedly connected by a snap fastener. A rubber pad 103 is installed on one side of the cover plate 102. When the cover plate 102 is installed, the rubber pad 103 can fit tightly against the nozzle, thus providing a certain buffer for the nozzle. Open the cover plate 102, and then manually turn the knob 106 at one end of the bidirectional screw 105. Driven by the knob 106, the bidirectional screw 105 is rotated. The two clamping plates 108 are respectively threaded onto the two ends of the bidirectional screw 105. On the side, the bottoms of both clamping plates 108 are in contact with the rectangular plate 104. A support plate 107 is installed on one side of the rectangular plate 104. A bidirectional screw 105 is located on the underside of the support plate 107. A slot 110 is provided at the bottom of the fixing box 101. The nozzle is engaged in the slot 110 and in contact with the support plate 107. The buffer pad 109 at one end of the two clamping plates 108 is used to stably clamp the nozzle. At this time, the distance between the two clamping plates 108 gradually increases as the bidirectional screw 105 rotates. After releasing the nozzle from its fixation, the nozzle is then removed along the slot 110 using a tool. When using the device, the consumable is inserted through the slot 205 between the two conveyor plates 203. Both conveyor plates 203 have arc-shaped slots in the middle. The two conveyor plates 203 are fixedly connected to the drive gear 201 and the driven gear 202, respectively. One side of the drive gear 201 is fixedly connected to the motor drive end, so the drive gear 201 rotates under the drive of the motor. Through the meshing of the conveyor plates 203 and the driven gear 202, the two conveyor plates 203 rotate towards each other, thereby driving the consumable between the two conveyor plates 203 to move downward. When installing the consumable, one end of the handle 204 is manually pressed. A spring 207 is connected between one end of the handle 204 and the support 206. The handle 204 is L-shaped. When the handle 204 rotates, the other end drives the driven gear 202 away from the drive gear 201, so that the consumable can be inserted between the two conveyor plates 203.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
