Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of additive manufacturing technology, and specifically relates to an additive manufacturing equipment recycling device. BACKGROUND

[0002] Additive manufacturing (AM), also commonly known as 3D printing, is a manufacturing technology that is different from traditional subtractive manufacturing (such as turning, milling, and grinding). The characteristic of additive manufacturing is to build three-dimensional solid parts by adding materials layer by layer. This technology can manufacture complex geometric structures that are difficult to achieve by traditional machining methods, and can quickly produce customized products and parts according to individual needs, using a variety of materials such as plastics, metals, ceramics, and fibers. Because materials are added on demand, compared with subtractive manufacturing, additive manufacturing can reduce material waste and allow rapid reprinting after design modification, speeding up the product development cycle. Common additive manufacturing technologies include stereolithography (SLA), selective laser melting (SLM), fused deposition modeling (FDM), powder bed fusion (PBF), and direct metal laser sintering (DMLS). The process involves using three-dimensional modeling software to design a digital model of the product, slicing the model into a series of two-dimensional cross sections, and using a printer to add materials layer by layer to build a three-dimensional entity according to the slicing information. After printing, post-processing steps such as support removal, polishing, and heat treatment may be required to obtain the final product. Additive manufacturing technology has been widely used in aerospace, automotive, medical, construction, education, and art, and its application range is still expanding as technology continues to advance.

[0003] The additive manufacturing equipment recycling device disclosed in Publication No. CN113799392A includes a working box body having a built-in working box and a feed hopper mounting seat provided on the top of the working box body. The main body of the device is used to collect waste generated after processing and to process the generated powder. The feed hopper has a feed mounting seat and is fixed above the feed hopper mounting seat for easy installation and corresponding positioning. The design of the inner inclined discharge hopper also facilitates powder discharge.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] like Figures 1-7As shown, an additive manufacturing equipment recycling device includes: a chassis 1, a power box 2 is provided on the back of the chassis 1, a motor assembly 4 is provided inside the power box 2, a bottom groove 12 is provided on one side of the bottom end of the chassis 1, a rectangular channel is opened on the inner side of the bottom groove 12, a pressing roller 3 is provided at the front end of the motor assembly 4, a front box 5 is provided on the front of the chassis 1, a rotating drum 8 is provided at the front end of the pressing roller 3, a shaft head 6 is provided on the outer side of the front end of the rotating drum 8, a wedge-shaped inner groove 7 is opened in the inner side of the shaft head 6, a rotating plate 15 is arranged in the outer front end of the rotating drum 8, an extension plate 14 is rotatably arranged on the inner side of the rotating plate 15, and a corner blade 13 is provided at one end of the extension plate 14.

[0028] The lower end of the front end of the chassis 1 is provided with a horizontal opening 9, the bottom end of the power box 2 is provided with an electric telescopic rod body 11, and the front end of the electric telescopic rod body 11 is provided with an auxiliary structure 10.

[0029] As for the rest, since the rotating drum 8 at the front end of the extrusion roller 3 is placed inside the shaft head 6, the user flips the corner blade 13 on the outside of the rotating drum 8. At the same time, the extension plate 14 at one end of the corner blade 13 cooperates with the rotating plate 15 to flip. After the corner blade 13 flips, it enters the inner side of the inner groove 7 and gets stuck. In this way, the corner blade 13 will restrict the rotating drum 8 and the extrusion roller 3 from rotating accidentally. The designer can increase the area or thickness of the corner blade 13 to increase the degree of fit of the corner blade 13 inside the inner groove 7.

[0030] This has resulted in the following effects and novel technologies:

[0031] This utility model provides a recycling device for additive manufacturing equipment. Through ingenious design, it achieves a safe locking of the extrusion roller 3 when not in use, preventing accidental rotation and improving the safety and reliability of the equipment. Specific effects and novel technologies are as follows: First, by setting a rotating drum 8 at the front end of the extrusion roller 3, and setting a shaft head 6 and a wedge-shaped inner groove 7 on the outer side of the front end of the rotating drum 8, along with a rotating structure composed of a rotating plate 15 and an extension plate 14, the locking function of the extrusion roller 3 is achieved. The user flips the corner blade 13, causing one end of the extension plate 14 to rotate in conjunction with the rotating plate 15. Finally, the corner blade 13 enters the inner groove 7 and locks in place, thereby restricting the rotation of the rotating drum 8 and the extrusion roller 3. Secondly, this design allows… The corner blade 13 can be enhanced by increasing its area or thickness to improve its fit within the inner groove 7, further improving the stability of the locking mechanism. In addition, the fixed connection between the rotating drum 8 and the extrusion roller 3 extends the range of motion of the extrusion roller 3, while the rotating structure between the extension plate 14 and the rotating plate 15 facilitates the rotation of the corner blade 13. Finally, the arc-shaped structure design of the corner blade 13 allows it to easily snap into the inner side of the inner groove 7, ensuring the smooth operation of the locking mechanism. This utility model achieves the safe locking of the extrusion roller 3 through a simple mechanical structure, reduces equipment maintenance costs, improves operational safety, and provides a novel and practical technical solution for the recycling device of additive manufacturing equipment.

[0032] like Figures 1-7 As shown, an additive manufacturing equipment recycling device includes an auxiliary structure 10 comprising a lever 101, a fixing plate 102, a drive rod 103, and a pivot rod 104. The front end of the electric telescopic rod body 11 is provided with the pivot rod 104. Fixing plates 102 are vertically arranged on both sides of the bottom end of the housing 1. A drive rod 103 is rotatably mounted on one side of the bottom end of the fixing plate 102. The front end of the drive rod 103 is provided with the lever 101. A rotating structure is formed between the portion of one side of the bottom end of the fixing plate 102 and the drive rod 103.

[0033] The rest are as follows: the electric telescopic rod body 11 linearly pushes the pivot rod 104 linearly, the pivot rod 104 pushes the drive rod 103 to rotate, the fixing plate 102 rotates in coordination with the drive rod 103, and the drive rod 103 drives the lever 101 to move at the bottom of the housing 1 and inside the horizontal opening 9. The lever 101 will push the material stuck inside the housing 1. The user can increase the area of ​​the lever 101 to increase the lever 101's turning force.

[0034] This has resulted in the following effects and novel technologies:

[0035] The additive manufacturing equipment recycling device provided by this utility model achieves effective material recycling and cleaning through the innovative design of the auxiliary structure 10. The specific effects and novel technologies are as follows: The linear push of the front pivot rod 104 of the electric telescopic rod body 11 is converted into the rotational motion of the drive rod 103. Then, through the rotational cooperation of the fixing plate 102, the lever 101 can be precisely moved between the bottom of the housing 1 and the inside of the horizontal opening 9. This design effectively pushes the material stuck inside the housing 1, ensuring the cleanliness of the housing 1 and the recycling of materials. The novelty lies in the fact that the conversion between the linear motion of the pivot rod 104 and the rotational motion of the drive rod 103 simplifies the operation process and improves the automation level of the device. In addition, the user can increase the area of ​​the lever 101 as needed to enhance the moving force. This design improves the applicability and flexibility of the device. This utility model brings a recycling device that is easy to operate, highly efficient, and highly applicable, providing innovative technical support for the material recycling of additive manufacturing equipment.

[0036] Working principle: When using this additive manufacturing equipment recycling device, the material is first placed inside the housing 1. The motor assembly 4 drives the extrusion roller 3 to rotate. When the extrusion roller 3 rotates, it presses the material structure. At the same time, the electric telescopic rod body 11 pushes the pivot rod 104 to move. The pivot rod 104 pushes the drive rod 103 to rotate. The drive rod 103 drives the lever 101 to rotate at the bottom of the housing 1 and inside the horizontal opening 9. The lever 101 will push the material stuck at the lower end of the housing 1. When the extrusion roller 3 is not in use, the rotating drum 8 at the front end of the extrusion roller 3 is placed inside the shaft head 6. The user flips the corner blade 13 on the outside of the rotating drum 8. The extension plate 14 at the lower end of the corner blade 13 cooperates with the rotating plate 15 to flip. After the corner blade 13 is flipped, it is stuck inside the inner groove 7 to prevent the rotating drum 8 and the extrusion roller 3 from rotating automatically without power. This is the working principle of the additive manufacturing equipment recycling device.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
