Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D self-service printing service terminal. Background Art

[0002] 3D printing is a technology that uses digital model files as the basis, thermoplastic materials and bondable materials to construct objects by printing layer by layer. Its characteristic is that it can print objects of most shapes. Compared with traditional manufacturing technology, 3D printing can produce relatively small quantities of products faster, more flexibly and at a lower cost. With the development of 3D printing, 3D printers have gradually entered people's daily lives. However, the price of 3D printers is relatively high. In order to reduce the cost of users, 3D self-service printing services came into being.

[0003] Traditional 3D printing terminals usually include a housing, a three-axis adjustment module arranged in the housing, a printing module for printing, and a support platform for carrying models. In the prior art, a hot bed is usually arranged on the support platform. In order to facilitate printing, there is usually a certain degree of adhesion between the bottom of the printed model and the hot bed. After the printing operation is completed, it is usually necessary to use a spatula or other tools to scrape the model off the hot bed. The operation is cumbersome, time-consuming and labor-intensive. Especially when performing self-service printing, it takes a lot of time to cut the model, which will have a certain impact on subsequent users. For this reason, we propose a 3D self-service printing service terminal to solve the above problems. Utility Model Content

The transmission arm is movably installed on the object platform through the guide rail and the guide sleeve. The transmission arm is restricted by the cooperation of the guide rail and the guide sleeve to ensure a stable connection between the transmission arm and the object platform, and at the same time, the transmission arm can drive the dividing knife to move stably.

[0008] As a further description of the above technical solution: the connecting claw is fixed to the end of the transmission arm by bolts, and a plug-in slot matching the splitting knife is opened inside the connecting claw. The end of the splitting knife is inserted into the plug-in slot and fixed by screws. The splitting knife is restricted by the plug-in slot and locked by screws to ensure the firmness of the splitting knife after installation and to ensure that the splitting knife can shovel the model stably.

[0009] As a further description of the above technical solution: blades are provided on the front and rear sides of the splitting knife, the bottom end of the splitting knife is flush with the bottom end of the blade, and a plurality of balancing holes are provided on the surface of the splitting knife. The plurality of balancing holes are provided on the splitting knife, which is helpful to destroy the negative pressure formed between the splitting knife and the model when the splitting knife cuts the model, thereby preventing the model from sticking to the splitting knife due to the negative pressure.

Since the dividing knife 18 is provided with a blade 19 on both the front and rear sides, and the bottom of the blade 19 is in contact with the top of the object support table 6, the dividing knife 18 can shovel the printed model along the top of the object support table 6 through the blade 19 when moving, so as to realize the rapid separation of the model and the object support table 6, and by providing a plurality of balancing holes 20 on the dividing knife 18, it is helpful to destroy the dividing knife 18 when cutting the model. The negative pressure formed between the knife 18 and the model prevents the model from sticking to the segmentation knife 18 due to the negative pressure; the segmentation knife 18 moves back and forth under the drive of the servo motor 12 to shovel the model off. For example, the last time the servo motor 12 drives the segmentation knife 18 to move from front to back to shovel the model off, the next time the servo motor 12 drives the segmentation knife 18 to move from back to front to shovel the model off; after the servo motor 12 drives the segmentation knife 18 to move to shovel the model off and stops, the controller 11 controls the air pump 23 to start, and the air pump 23 introduces airflow into the cleaning air pipe 21 along the connecting pipe 24, and makes the airflow spray out along the air nozzle 22, and the surface of the segmentation knife 18 is sprayed by the flowing airflow, and the surface of the segmentation knife 18 is cleaned to prevent the segmentation knife 18 from having plastic residue on the surface when scraping the model, and to ensure that the surface of the segmentation knife 18 is clean, so as to facilitate the segmentation knife 18 to shovel the model off later.
