[0046] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. It is usually achieved using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields. After 3D printing, a part of the printing waste will remain. Directly discarding the printing waste will cause a lot of waste. Therefore, waste recycling equipment will be used to recycle it. Materials that can be melted and re-molded can be recycled and put back into use.

[0047] In the related art, the device has a complex structure and uses the force of a spring to make it rebound, so that the screening box shakes back and forth, which can easily cause damage to other components in the screening box. Moreover, after the waste is screened, the larger waste cannot be cleaned up, causing the larger waste to block the holes on the filter plate, reducing its screening efficiency.

[0048] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a waste recycling device for 3D printing. When it is needed, the waste only needs to be put into the feed port 15, and then the motor 16 is started by an external power supply. The output end of the motor 16 drives the first rotating rod 161 and the first crushing roller 17 to rotate. At the same time, the first rotating rod 161 drives the first gear 18 to rotate. The first gear 18 drives the second gear 181 to rotate by meshing with the second gear 181, and drives the second rotating rod 162 and the second crushing roller 171 to rotate. The rotating first crushing roller 17 and the second crushing roller 171 will crush the waste put into the feed port 15, and the crushed waste will fall into the screening basket 21. At this time, the vibration motor 23 is started, and the vibration motor 23 drives the screening basket 21 to vibrate to screen the waste in the screening basket 21. Excessive waste will remain in the screening basket 21 and will not affect other components of the cabinet 11.

[0049] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0050] Combination Figure 1-Figure 7The embodiment of the present application provides a waste recycling device for 3D printing, including a device body 1, which includes: a base 12 is arranged at the bottom of a cabinet 11; a sealing door 13 is arranged on the outside of the cabinet 11; a feed port 15 is arranged at the top of the cabinet 11; a motor 16 is arranged on one side of the cabinet 11; a first rotating rod 161 is arranged at the output end of the motor 16 and passes through the cabinet 11, a first crushing roller 17 is arranged on the outside of the first rotating rod 161 and is located inside the cabinet 11; a first gear 18 is arranged at one end of the first rotating rod 161, a second gear 181 is arranged on the outside of the first gear 18 and is meshed with the second gear 181, a second rotating rod 162 is arranged on the second gear 181 and passes through the second gear 181 and the outer wall of the cabinet 11, a second crushing roller 171 is arranged on the outside of the second rotating rod 162 and is located inside the cabinet 11. A screening assembly 2 is provided inside the cabinet 11 and is located below the first crushing roller 17 and the second crushing roller 171. The screening assembly 2 includes: a support plate provided on the inner wall of the cabinet 11; a vibration motor 23 provided on the top of the support plate; a first connecting block 231 provided on the top of the vibration motor 23; a screening basket 21 provided on the top of the first connecting block 231; and an auxiliary assembly 3 provided on one side of the screening basket 21.

[0051] When using the waste recycling device for 3D printing, firstly, the waste is put into the feed port 15, and then the motor 16 is started by an external power supply. The output end of the motor drives the first rotating rod 161 and the first crushing roller 17 to rotate, and at the same time, the first rotating rod 161 drives the first gear 18 to rotate. The first gear 18 drives the second gear 181 to rotate by meshing with the second gear 181, and drives the second rotating rod 162 and the second crushing roller 171 to rotate. The rotating first crushing roller 17 and the second crushing roller 171 will crush the waste put into the feed port 15, and the crushed waste will fall into the screening basket 21. At this time, the vibration motor 23 is started, and the vibration motor 23 drives the screening basket 21 to vibrate, so as to screen the waste in the screening basket 21. The waste that is too large will remain in the screening basket 21, and will not affect other components of the cabinet 11.

[0052] Specifically, the model of the vibration motor 23 is YZS5-6, and the working principle is based on the principles of electromagnetic force and mechanical vibration. Specifically, the vibration motor 23 includes a fixed iron core, a coil wound with copper wire, and a rotatable eccentric wheel. When current passes through the coil, a rotating magnetic field is generated. This magnetic field causes the eccentric wheel to be unbalanced, resulting in vibration. By adjusting the magnitude and frequency of the current, the vibration amplitude and frequency of the vibration motor can be controlled.

[0053] In some embodiments, a spring 24 cooperating with the vibration motor 23 is provided on the top of the first support plate 22. Due to the rebound movement of the spring 24 after being subjected to force, the screening basket 21 is driven to vibrate, and the stability of the screening basket 21 driven to vibrate by the vibration motor 23 is increased. A second connecting block 241 is provided on the top of the spring 24.

[0054] In some embodiments, a slide plate 25 is provided on the top of the first connecting block 231 and the second connecting block 241, and a slide groove 26 matching the slide plate 25 is provided at the bottom of the screening basket 21, so that the screening basket 21 is slidably connected with the vibration motor 23 and the spring 24. When there is too much oversized waste in the screening basket 21, the sealing door 13 is opened to directly pull out the screening basket 21 through the slide groove 26, and the oversized waste in the screening basket 21 is cleaned up, which increases the convenience of cleaning the oversized waste and avoids the situation where the larger waste cannot be cleaned up after the waste is screened, resulting in the larger waste blocking the holes on the screening basket 21 and reducing its screening efficiency. The cleaned oversized waste is put back into the feed port 15 for crushing again.

[0055] In some embodiments, the auxiliary component 3 includes: a positioning plate 31 is arranged on one side of the screening basket 21, and a positioning groove 32 matching the positioning plate 31 is arranged on the inner wall of the cabinet 11. When the screening basket 21 is installed, the positioning plate 31 is inserted into the positioning groove 32, and the slide groove 26 at the bottom of the screening basket 21 can be easily slidably connected with the spring 24 and the slide plate 25 on the top of the vibration motor 23, and the screening basket 21 can be installed in the cabinet 11.

[0056] In some embodiments, a telescopic tube 242 of the spring 24 is provided on the top of the first support plate 22 and is located on the inner side of the spring 24 to support the spring 24 to prevent the spring 24 from bending after high-intensity vibration, which causes excessive deviation in the supporting force of the spring 24 at both ends of the screening basket 21 on the ground, thereby increasing the stability of the screening basket 21.

[0057] In some embodiments, a water pump 14 is provided on the top of the base 12, and a water pipe 141 is provided on one side of the water pump 14. An atomizing nozzle 142 cooperating with the first crushing roller 17 and the second crushing roller 171 is provided inside the cabinet 11, and is fixedly connected to one end of the water pipe 141. A large amount of dust will be generated when the crushing rollers crush the waste. The water source is brought by the water pump 14 and transported to the atomizing nozzle 142 through the water pipe 141. The atomizing nozzle 142 is used to spray water mist inside the cabinet 11 to clean the dust, thereby preventing dust from floating out of the cabinet 11 and entering the motor to cause malfunctions and air pollution.

[0058] In some embodiments, a shock-absorbing rubber pad 163 is provided on one side of the cabinet 11 to cooperate with the motor 16, which can reduce the vibration generated when the motor 16 is running under load and avoid affecting other components in the cabinet 11. A second support plate 164 is provided at the bottom of the motor 16 to support the motor 16 and have a certain stability.

[0059] Specifically, the shock-absorbing rubber pad 163 is a functional soft material that can effectively reduce equipment noise and vibration. Its principle is: when an object moves or vibrates, the air in the rubber can convert this energy into heat energy to reduce the kinetic energy of movement or vibration, thereby slowing down the impact, reducing noise, reducing vibration and extending service life, ultimately achieving better use results.

[0060] In some embodiments, a receiving trough 19 is provided inside the cabinet 11 and is located below the screening basket 21. After the waste is crushed by the crushing roller, the qualified waste will fall from the screening basket due to vibration and fall into the receiving trough 19, where it will be recycled and re-molded for reuse after being melted.

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0062] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
