Description

Technical Field

[0001] The present application relates to the field of waste recycling of 3D printing materials, and particularly to a waste recycling device. Background Art

[0002] 3D printing is a type of rapid prototyping technology, usually realized by using a digital technology material printer. It is often used in the fields of mold manufacturing, industrial design, etc. to manufacture models, and later gradually used for the direct manufacturing of some products. 3D printing technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.

[0003] In dentistry, mostly biocompatible photocurable 3D printing resin materials are used for 3D printing to produce implant surgical guides, orthodontic guides, functional retainers, orthodontic attachments, bite plates, bite pads, and X-ray guides, etc. The materials have high forming speed and high mechanical strength and are easy to polish. At the same time, the tensile strength, elasticity, and low water absorption can meet the requirements of the guide material.

[0004] Regarding the above related technologies, the inventor believes that there are defects in that a large amount of waste is usually generated during 3D printing using a digital technology material printer, and directly discarding the waste will cause material waste. Utility Model Content

[0005] In order to recycle and reuse a large amount of waste generated during 3D printing, the present application provides a waste recycling device.

[0006] A waste recycling device provided by the present application adopts the following technical solutions:

[0007] A waste recycling device includes a crushing mechanism. The crushing mechanism includes a first housing, a crushing component disposed in the first housing for crushing waste, and a filtering component disposed directly below the crushing component for screening the crushed waste; a plurality of discharge ports are formed in the first housing opposite to the filtering component; and a bracket is disposed on a surface of the first housing close to the ground.

[0008] By adopting the above technical solutions, the crushing mechanism is supported on the ground by the bracket. The waste generated by 3D printing is first preliminarily crushed by the crushing component in the crushing mechanism. After crushing, the waste is filtered and grouped by the filtering component directly below the crushing mechanism according to different degrees of crushing. Then, the crushed waste of different sizes is discharged through different discharge ports. After separating the waste of different sizes, it can be adapted to different usage conditions and can be reused as needed.

[0009] Preferably, the filter assembly includes a filter basket arranged directly below the crushing assembly, a plurality of filter plates installed on the inner wall of the first shell and located directly below the filter basket, and a discharge plate installed on the inner wall of the first shell and located directly below the plurality of filter plates; the plurality of filter plates are parallel to each other, and the discharge plate and the filter plates are parallel to each other.

[0010] By adopting the above technical scheme, the waste crushed by the crushing assembly first passes through the filter basket to filter out the oversized waste, and then passes through multiple filter plates. Different filter plates have different sizes of filter holes, so the sizes of waste filtered out are also different. Finally, when it reaches the discharge plate, it is the smallest waste. Waste of different sizes is discharged from different discharge ports for use, and the waste in the filter basket needs to be taken out and crushed again by the crushing mechanism.

[0011] Preferably, the filter basket includes a basket body and a filter net, the basket body is vertically fixed to the filter net, the basket body and the first shell are connected by a plurality of springs, a first handle is fixed to the surface of the basket body close to the first shell, and a first clearance opening is opened on the first shell for the first handle to pass through and move.

[0012] By adopting the above technical solution, when using the filter basket for filtering, shaking the filter basket by the first handle can accelerate the filtration. During the filtering process, the basket prevents the waste from splashing when the waste is shaken, and smaller waste is filtered through the filter screen onto the filter plate.

[0014] By adopting the above technical solution, when waste falls onto the filter plate, the setting of a spring with one end hinged and the other end can cause the filter plate to vibrate through the force of the waste falling on the filter plate body, thereby achieving a filtering effect.

[0015] Preferably, a second handle is fixedly connected to one side of the baffle plate where the spring is arranged, a second clearance opening is opened on the first shell for the second handle to move through, and the side of the filter plate close to the second handle is higher than the side hinged to the first shell.

[0017] Preferably, a plurality of the discharge ports are arranged at one ends of the plurality of filter plates away from the second relief opening and at one ends of the discharge plate away from the second relief opening, and the plurality of discharge ports communicate the inside and outside of the first housing, and discharge valves are arranged at the plurality of discharge ports.

[0018] By adopting the above technical solution, the plurality of discharge ports correspond to different filter plates, so that waste materials of different sizes are discharged through different discharge ports, and the discharge valves can control the discharging of the discharge ports, achieving the purpose of discharging materials separately or simultaneously.

[0019] Preferably, a heating mechanism is further included. The heating mechanism includes a second housing, a first heating component arranged in the second housing and fixedly connected to the inner wall of the second housing, a second heating component located directly below the first heating component, a discharge pipe communicated with the second heating component, and a discharging component for applying pressure to the material in the discharge pipe to facilitate discharging; a first discharge pipeline is communicated between the first housing and the second housing; the discharging component is arranged close to the crushing mechanism; and one end of the discharge pipe away from the discharging component is fixedly connected with an extrusion opening communicating the inside and outside of the discharge pipe.

[0020] By adopting the above technical solution, for waste materials with larger sizes, they are sent to the heating mechanism through the first discharge pipe, and then are preliminarily heated by the first heating component. When the waste materials are melted to a certain extent, they will reach the second heating component through the first heating component, and then the waste materials are completely heated into a liquid. Then the liquid flows into the discharge pipe, and the discharging component discharges the liquid in the discharge pipe from the extrusion opening. The discharged waste materials can be reused by products such as 3D printing pens.

[0021] Preferably, the outer surface of the extrusion opening is a threaded structure, and an extrusion head is threadedly connected to the extrusion opening.

[0022] By adopting the above technical solution, for different requirements, different sizes of extrusion heads can be replaced through the threaded structure to obtain strip-shaped objects made of waste materials with different sizes, so as to adapt to different printing pens.

[0033] The following is a further detailed description of the present application in combination with the attached Figures 1-4 drawings.

[0034] The embodiment of the present application discloses a waste recycling device. Refer to Figure 1 and Figure 2, the waste recycling device includes a crushing mechanism 1 and a heating mechanism 2 connected to the crushing mechanism 1 for reprocessing the waste. The crushing mechanism 1 includes a first housing 11, a crushing assembly 12 disposed in the first housing 11 for crushing the waste, and a filtering assembly 13 disposed in the first housing 11 and directly below the crushing assembly 12.

[0035] Referring to Figure 2 and Figure 3 , the first housing 11 can be a cylindrical structure or a cuboid structure. In this embodiment, the cuboid structure is used for illustration. The interior of the first housing 11 is hollow, and a feed hopper 14 communicating the inside and outside of the housing is fixedly connected to the top of the housing. A support 15 is provided on the outer surface of the first housing 11 close to the ground. The crushing assembly 12 is disposed directly below the feed hopper 14. The crushing assembly 12 includes a plurality of crushing cylinders 121. The number of crushing cylinders 121 is at least two. In this embodiment, two crushing cylinders 121 are taken as an example for illustration. The crushing cylinders 121 are cylindrical structures. The axes of the two crushing cylinders 121 are in the same plane and the two crushing cylinders 121 mesh with each other. The waste can be preliminarily crushed into small pieces of different sizes by the crushing cylinders 121. The crushed waste will fall into the filtering assembly 13 directly below the crushing cylinders 121 for filtering.

[0036] Referring to Figure 3 , the filtering assembly 13 includes a filtering basket 131 disposed directly below the crushing assembly 12, a plurality of filter plates installed on the inner wall of the first housing 11 and directly below the filtering basket 131, and a discharge plate 134 installed on the inner wall of the first housing 11 and directly below the filter plates.

[0037] Referring to 2 and Figure 3 , the filtering basket 131 includes a basket body and a filter net. One side of the basket body is perpendicularly fixedly connected to the filter net. During installation, the basket body faces the crushing cylinders 121. Two sides of the basket body in the same rotation direction as the crushing cylinders 121 are respectively installed on the inner wall of the first housing 11 through a plurality of springs 16. A first handle 135 is fixedly connected to any side of the basket body where the springs 16 are provided. A first relief opening through which the first handle 135 passes and moves is provided on the first housing 11. When using the filtering basket, the first handle 135 can be held to shake the filtering basket, so that the waste with particularly large size can be left in the filtering basket, and the waste of other sizes continues to reach the filter plates below. A door 17 that can be opened is provided at the position of the first housing 11 corresponding to the filtering basket 131. After preliminary filtering through the filtering basket 131, the door 17 is opened to take out the waste in the filtering basket 131 and then perform secondary crushing through the crushing cylinders 121.

[0038] Referring to Figure 2 and Figure 3, there are at least two filter plates. In this embodiment, three filter plates are taken as an example for illustration. The three filter plates are arranged in sequence along the longitudinal height of the first housing 11 and are parallel to each other within the first housing 11. The filter plate includes a filter plate body 133 and baffles 132 arranged around three sides of the filter plate body 133. The pore sizes of the filter plate body 133 between the three baffles 132 are different. The pores of the filter plate body 133 closest to the filter basket 131 are the largest, and then the pore sizes of the filter plate body 133 gradually decrease along the height direction. During use, when the shredded waste passes through the three filter plates, different-sized filter plates can be left according to the different pore sizes.

[0039] Refer to Figure 2 and Figure 3 , the baffle 132 is vertically and fixedly connected to the filter plate body 133, and every two adjacent baffles 132 are vertically and fixedly connected. The side of the filter plate without the baffle 132 is hinged to the inner wall of the first housing 11. The baffle 132 opposite to the side without the baffle 132 is directly connected to the first housing 11 through a plurality of springs 16, and a second handle 136 is provided on the surface of this baffle 132 facing the first housing 11. A second relief opening for the second handle 136 to pass through and move is provided on the first housing 11. When the waste is on the filter plate, shaking the filter plate body 133 through the second handle 136 can accelerate filtration, and the baffle 132 plays a role in preventing the waste from splashing everywhere.

[0040] Refer to Figure 2 and Figure 3 , the end of the filter plate provided with the second handle 136 is higher than the end hinged to the inner wall of the first housing 11, making the filter plate inclined at a certain angle to facilitate subsequent discharging. The discharging plate 134 is arranged parallel to the filter plate. A plurality of discharging ports 18 are provided on the first housing 11 at the end of the filter plate away from the second handle 136. The discharging ports 18 are respectively arranged corresponding to the three filter plates and the discharging plate 134. A discharging valve 19 is provided at each discharging port 18. After using the filter plate to filter the waste, the finest and smallest waste will reach the discharging plate 134 and be discharged through the discharging port 18 at the discharging plate 134, while the waste of different sizes left on different filter plates is discharged through the corresponding discharging ports 18.

[0041] Refer to Figure 3 and Figure 4, a first discharge pipe 3 is connected to the discharge port 18 near the filter basket 131, and the other end of the first discharge pipe 3 is connected to the heating mechanism 2. The heating mechanism 2 includes a second housing 21, a first heating component 22 disposed inside the second housing 21 and fixedly connected to the inner wall of the second housing 21, a second heating component 23 located directly below the first heating component 22, a discharge pipe 24 communicating with the second heating component 23, and a discharging component 25 for applying pressure to the material in the discharge pipe 24 to facilitate discharging. The second housing 21 is a square housing, and the first discharge pipe 3 is connected to the side wall of the second housing 21 near the top, and the connection point is above the first heating component 22.

[0042] Referring to Figure 4 , the first heating component 22 includes a heating plate with filter holes. When large pieces of waste reach the first heating component 22, the first heating component 22 can preliminarily heat the waste, and after melting, it flows through the filter holes to the second heating component 23. The second heating component 23 is an arc-shaped structure and can perform secondary heating on the waste that has been preliminarily heated and melted. A plurality of discharge holes 231 are opened at the lowest point of the second heating component 23, and the melted waste flows into the discharge pipe 24 through the discharge holes 231. Then, the discharging component 25 squeezes the inside of the discharge pipe 24 to discharge the waste from the extrusion port 241. The extrusion port 241 is a threaded structure, and extrusion heads 242 of different sizes can be installed according to different requirements, so as to obtain materials of different thicknesses and shapes. The obtained materials can be reused with equipment such as a 3D printing pen.

[0043] Referring to Figure 2 and Figure 4 , the discharging component 25 is disposed near the crushing component 12. The discharging component 25 includes a movable cylinder 251 and a pressing plug 252 connected to the piston rod of the movable cylinder 251 and disposed inside the discharge pipe 24. A plurality of sets of discharging components 25 are provided. In this embodiment, four sets are taken as an example for illustration. The four sets of discharging components 25 are arranged side by side and located at the bottom of the second housing 21. Corresponding to the four sets of discharging components 25 are four discharge pipes 24. Extrusion heads 242 of different sizes can be installed at the extrusion ports 241 of the four discharge pipes 24, so as to obtain materials of different sizes simultaneously. During use, the movable cylinder 251 drives the piston rod to move, thereby driving the pressing plug 252 to move, achieving the purpose of squeezing and discharging the material inside the discharge pipe 24.

[0044] The implementation principle of the embodiment of this application is as follows: The crushing mechanism 1 is supported on the ground by the bracket 15. The waste generated by 3D printing is first preliminarily crushed by the crushing component 12 in the crushing mechanism 1. After crushing, the waste is filtered and grouped according to different degrees of crushing through the filter box and filter plate directly below the crushing mechanism 1. Then, the crushed waste of different sizes is discharged through different discharge ports 18. After separating the waste of different sizes to adapt to different usage conditions, it can be reused as needed. For the waste with larger sizes, it is sent to the heating mechanism 2 through the first discharge pipe 3, and then preliminarily heated by the first heating component 22. When the waste melts to a certain extent, it will reach the second heating component 23 through the first heating component 22, and the waste is completely heated into a liquid. Then, the liquid flows into the discharge pipe 24, and the liquid in the discharge pipe 24 is discharged from the extrusion port 241 through the discharging component 25. The discharged waste can be reused by products such as 3D printing pens.
