Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing printing waste collection, and in particular to an additive manufacturing waste collection device. Background Art

[0002] Additive manufacturing is a technology that builds objects by adding materials layer by layer. Compared with traditional subtractive manufacturing, additive manufacturing theoretically has a higher material utilization rate, but there are still several situations that will generate a certain amount of waste.

[0003] First, during the 3D printing process, the printer builds up material layer by layer according to computer instructions to form the final product. Due to the layer-by-layer nature of the printing process, as well as the temporary support material added to support the structure, this temporary support material needs to be removed after printing is completed, resulting in a certain amount of waste.

[0004] Secondly, after printing is complete, some post-processing is required, such as support structure removal and surface treatment, which may generate waste. Print failures and residual material can also generate some waste. This is especially true during power outages or other power supply issues, which can interrupt printing and even damage the printer or the part being printed, resulting in a failed print. Furthermore, a small amount of printed material often remains during printing, insufficient for further printing, and thus becomes waste.

[0005] Most of these waste materials are made of materials such as plastic, metal, and ceramics, which have a significant negative impact on the ecological environment. After multi-color printing, the amount of waste is huge and it is difficult to handle.

[0006] In the existing technology, the collection of such waste materials generally involves first classifying and collecting 3D printing waste by material type, followed by pulverization, which breaks the waste into pieces of a certain size for easier processing. Separation and purification are then carried out, using physical or chemical methods to separate and purify the different materials.

[0007] Some physical recycling methods include mechanical grinding, which uses grinding equipment to grind waste into powder that can be directly used in 3D printing. Other methods include high-temperature melting, which heats the waste to its melting point to form liquid metal or plastic, which is then cooled and solidified.

[0008] As mentioned above, various waste materials need to be collected first, and then classified and processed according to different materials. However, the shapes and sizes of the same type of waste are different, and the crushed waste materials are of different sizes, which is not conducive to sufficient dissolution in the subsequent fusion process. The difference in color can easily lead to partial incomplete fusion of the fused waste, resulting in color defects in the finished product. Summary of the Invention

[0009] In view of this, the present invention aims to provide an additive waste collection device to improve the uniformity of crushing and ensure the waste fusion effect.

[0010] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0012] The transmission and screening mechanism includes a second transmission part and a screening part provided at the outlet of the second transmission part;

[0013] The screening part includes a mounting plate and a plurality of screening rods arranged at intervals on the mounting plate. The mounting plate and the side ends of the transmission part are provided with flow openings, and the waste is transmitted to the collection mechanism through the gaps between the screening rods and the flow openings.

[0016] Furthermore, the second transmission part includes a second frame, a second transmission belt provided on the second frame, and a second driving part for driving the second transmission belt;

[0017] A plurality of guide wheels arranged at intervals are provided on a side of the second frame close to the flow port. The guide wheels are pivotally connected to the mounting shaft, and the mounting shaft is arranged along the height direction of the second frame.

[0018] Furthermore, the mounting plate is provided with a fixed shaft extending toward the second conveyor belt, the screening rod is pivotally connected to the fixed shaft, and the fixed shaft and the screening rod are arranged in a one-to-one correspondence.

[0019] Furthermore, the first collecting part includes a base, a first receiving hopper provided on the upper part of the base, a crushing shaft provided below the first receiving hopper, a third driving part for driving the crushing shaft to rotate, and a storage bin provided below the crushing shaft;

[0020] The two crushing shafts are relatively pivotally connected to the base, and the waste is crushed by being squeezed by the two crushing shafts;

[0021] The spiral feeding part is connected to the storage bin.

[0022] Furthermore, the power output end of the third driving unit is connected to one of the pulverizing shafts, and the two pulverizing shafts are connected through a sprocket and a chain transmission;

[0023] A receiving plate for receiving the waste is further provided below the crushing shaft, a receiving cavity is provided at the lower part of the base and passes through in the longitudinal direction, and a driving mechanism is provided at one end of the other crushing shaft, and the driving mechanism is used to drive the receiving plate to swing back and forth;

[0024] The receiving plate is provided with a plurality of through holes, and the plurality of through holes form a screen, and the waste material falls into the storage bin through the through holes.

[0025] Furthermore, the driving mechanism includes a turntable connected to the other pulverizing shaft, a swing arm slidably connected to the turntable, and a driving plate connected to the receiving plate on a side facing the turntable;

[0026] The driving plate is provided with a first tooth-shaped portion protruding upward, and the rocker arm is provided with a second tooth-shaped portion transmission-connected to the first tooth-shaped portion;

[0027] An extension shaft is provided on the base, and the swing arm is pivotally connected to the extension shaft.

[0028] Furthermore, a lower rotating drum and an upper rotating drum are pivotally connected in the accommodating cavity, and the upper rotating drum and the lower rotating drum are both abutted against two side walls of the base along the width direction of the base;

[0029] The receiving plate is arranged between the upper rotating drum and the lower rotating drum.

[0030] Furthermore, the upper plane of the receiving plate is higher than the upper plane of the first receiving hopper, and a shift plate extending along its own width is provided in the middle of the receiving plate.

[0031] Furthermore, the receiving plate is formed into an arc plate, and both ends of the arc plate are constructed around the outside of the first receiving hopper.

[0032] Furthermore, the first transmission unit includes a first frame, a first transmission belt provided on the first frame, and a first driving unit for driving the first transmission belt;

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] The additive waste collection device described in the present invention screens waste materials of different shapes or volumes during the transmission process by setting up a transmission and screening mechanism. Smaller waste materials flow into the first collecting part and the second collecting part through the gap between the two screening rods. Waste materials with larger volumes that cannot pass through the gap between the two screening rods are introduced into the first collecting part from the flow port. After the first collecting part performs screening on one side, the waste materials crushed in the first collecting part are transported to the second collecting part through the spiral feeding part for re-crushing, thereby improving the uniformity of the waste crushing and facilitating the fusion effect of the subsequent fusion process.

[0036] In addition, by arranging a receiving plate under the crushing shaft, the driving mechanism drives the receiving plate to swing back and forth. During the swinging process, some of the crushed small-volume waste falls into the storage bin through the through hole. When the large-volume waste swings to the top of the first receiving hopper with the paddle plate, it is separated from the paddle plate due to the stop of the receiving plate and enters the first receiving hopper for multiple crushing until the crushed volume can be screened through the through hole and fall into the storage bin. By crushing the waste of the same volume again in the second collecting part, waste with similar particle size is obtained, thereby further ensuring the uniformity of crushing.

[0060] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0061] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "back" and other terms indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] Furthermore, in the description of the present invention, unless otherwise expressly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will appreciate the specific meanings of these terms in the present invention based on the specific circumstances.

[0063] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0064] This embodiment relates to an additive waste collection device, comprising a conveying and screening mechanism 1, a collection mechanism 2 disposed below the outlet of the conveying and screening mechanism 1, and a first conveying section 3 disposed below the collection mechanism 2. The conveying and screening mechanism 1 comprises a second conveying section 101 and a screening section 102 disposed at the outlet of the second conveying section 101. The screening section 102 comprises a mounting plate 1021 and a plurality of screening rods 1022 spaced apart on the mounting plate 1021. A flow opening 1023 is provided between the mounting plate 1021 and the side end of the conveying section. Waste is conveyed to the collection mechanism 2 through the gaps between the screening rods 1022 and the flow opening 1023.

[0065] The collection mechanism 2 includes a first collection section 201 located below the flow port 1023 and a second collection section 202 arranged parallel to the first collection section 201. Both the first collection section 201 and the second collection section 202 are used to crush waste and collect the crushed waste. A spiral feeder 203 is provided at the bottom of the first collection section 201 to transport the crushed waste from the first collection section 201 to the second collection section 202.

[0066] The additive waste collection device of this embodiment screens waste of different shapes or volumes during the transmission process by setting up a transmission and screening mechanism 1. Smaller waste flows into the first collecting part 201 and the second collecting part 202 through the gap between the two screening rods 1022. Waste with a larger volume that cannot pass through the gap between the two screening rods 1022 is introduced into the first collecting part 201 through the flow port 1023. After the first collecting part 201 performs one-side screening, the waste crushed in the first collecting part 201 is transported to the second collecting part 202 by the spiral feeding part 203 for re-crushing, thereby improving the uniformity of the waste crushing and facilitating the fusion effect of the subsequent fusion process.

[0067] Based on the above overall introduction, if Figures 1 to 3 As shown, the additive waste collection device of this embodiment serves as an automatic collection device for centralized additive waste processing. It is mainly used in the waste collection stage and is a device for screening and crushing waste. It can be used in an additive waste production line or used alone.

[0068] Among them, such as Figures 1 to 3 As shown, the transmission and screening mechanism 1 is arranged at the front end, and the collected waste of the same material is evenly laid on the second transmission part 101. After the waste of different shapes and volumes is screened by the screening part 102, the screened waste is crushed separately by the first collecting part 201 and the second collecting part 202 to obtain more uniform waste particles.

[0069] As a preferred embodiment, Figures 1 to 3 As shown, the second conveying unit 101 includes a second frame 1011, a second conveyor belt 1012 mounted on the second frame 1011, and a second driving unit 1013 for driving the second conveyor belt 1012. A plurality of guide wheels 1014 are provided on a side of the second frame 1011 near the flow opening 1023. The guide wheels 1014 are pivotally connected to a mounting shaft 1015 disposed along the height of the second frame 1011.

[0070] In this embodiment, the second drive unit 1013 utilizes a rotary motor. A second driving shaft and a second driven shaft are pivotally connected to the second frame 1011. The power output of the second drive unit 1013 is connected to the second driving shaft, each of which is equipped with a pulley. The second transmission belt 1012 and the pulleys are driven by the motor to transmit the power. In this embodiment, three mounting shafts 1015 are disposed at the rear end of the second frame 1011 along the transmission direction of the second transmission belt 1012. Each mounting shaft 1015 is equipped with three spaced guide pulleys 1014. Deep groove ball bearings connect the guide pulleys 1014 to the mounting shafts 1015. This arrangement facilitates the passage of larger waste materials.

[0071] Preferably, if Figure 2 and Figure 3 As shown, the mounting plate 1021 is provided with a fixed shaft extending toward the second conveyor belt 1012, and the screening rod 1022 is pivotally connected to the fixed shaft, and the fixed shaft and the screening rod 1022 are arranged in a one-to-one correspondence. Figure 2 and Figure 3 As shown, the fixed shaft is plugged and fixed to the mounting plate 1021, and deep groove ball bearings are provided at the upper and lower ends between the screening rods 1022 and the fixed shaft, which makes it easier for waste to pass through the gap between the two screening rods 1022 and avoids jamming.

[0072] In addition, if Figures 4 to 7 As shown, the first collecting unit 201 includes a base 2011, a first receiving hopper 2012 disposed above the base 2011, a crushing shaft 2013 disposed below the first receiving hopper 2012, a third driving unit 2014 that drives the crushing shaft 2013 to rotate, and a storage bin disposed below the crushing shaft 2013. The two crushing shafts 2013 are pivotally connected to the base 2011 relative to each other, and waste is crushed by the two crushing shafts 2013. The spiral feed unit 203 is connected to the storage bin.

[0073] The first receiving hopper 2012 is a tapered cone that tapers downward from top to bottom, facilitating waste collection. Furthermore, the second collecting section 202 in this embodiment has the same structure as the first collecting section 201 and will not be further described here. The second receiving hopper 2024 on the second collecting section 202 is connected to and arranged side by side with the first receiving hopper 2012, ensuring that all waste enters the receiving chamber 2017 described below for crushing.

[0074] Further, as Figures 4 to 7 As shown, the power output end of the third drive unit 2014 is connected to one of the pulverizing shafts 2013. The two pulverizing shafts 2013 are connected via a sprocket and chain transmission. A receiving plate 2016 for receiving waste is located below each of the pulverizing shafts 2013. A longitudinally extending receiving cavity 2017 is provided at the bottom of the base 2011. A drive mechanism is provided at one end of the other pulverizing shaft 2013 to drive the receiving plate 2016 back and forth. The receiving plate 2016 is provided with a plurality of through-holes 20161, which form a screen through which waste falls into a storage bin.

[0075] The third driving part 2014 adopts a driving motor. Through the drive of the third driving part 2014, the two crushing shafts 2013 rotate inward at the same time. The crushing shaft 2013 is provided with a blade in the radial direction. The structure of the crushing shaft 2013 is the same as the crushing shaft 2013 in the crusher in the prior art, and will not be repeated here.

[0076] In this embodiment, a receiving plate 2016 is set below the crushing shaft 2013, and the driving mechanism drives the receiving plate 2016 to swing back and forth. During the swinging process, some of the crushed small-volume waste falls into the storage bin 2015 through the through hole 20161. When the large-volume waste swings to the top of the first receiving hopper 2012 with the shifting plate 2025, it is separated from the shifting plate 2025 due to the stop of the receiving plate 2016 and enters the first receiving hopper 2012 for multiple crushing until the crushed volume can be screened through the through hole 20161 and fall into the storage bin 2015. By crushing the waste of the same volume again in the second collecting part 202, waste with similar particle size is obtained, thereby further ensuring the uniformity of crushing.

[0077] As a preferred embodiment, Figures 6 to 9 As shown, the drive mechanism includes a rotating disk 2018 connected to the other pulverizing shaft 2013, a swing arm 2019 slidably connected to the rotating disk 2018, and a drive plate 2020 connected to the side of the receiving plate 2016 facing the rotating disk 2018. The drive plate 2020 is provided with an upwardly projecting first tooth-shaped portion 20201, and the swing arm 2019 is provided with a second tooth-shaped portion 20191 drivingly connected to the first tooth-shaped portion 20201. The base 2011 is provided with an extension shaft 2021, and the swing arm 2019 is pivotally connected to the extension shaft 2021.

[0078] like Figure 6 and Figure 8 As shown, the turntable 2018 is a circular disc-shaped structure with a protruding cam 20181 on the turntable 2018. A long groove 20192 is formed on the swing arm 2019, the width of which matches the diameter of the cam 20181. One end of the extension shaft 2021 is fixed to one side of the base 2011, and the other end is connected to the swing arm 2019 via a deep groove ball bearing. When the turntable 2018 rotates with the crushing shaft 2013, the cam 20181 rotates along the center of the crushing shaft 2013, driving the swing arm 2019 to swing back and forth. Through the meshing transmission of the first tooth-shaped portion 20201 and the second tooth-shaped portion 20191, the receiving plate 2016 swings back and forth accordingly.

[0079] It should be pointed out that the swing angle can be determined according to the distance between the cam 20181 and the center of the crushing shaft 2013. Therefore, adaptive adjustment can be made for waste materials of different materials or shapes. Therefore, multiple threaded holes can be set on the turntable 2018, and a protruding threaded portion is provided on the cam 20181 to facilitate the adjustment of the position of the cam 20181 as needed.

[0080] Furthermore, if Figures 6 to 10As shown, a lower rotating cylinder 2022 and an upper rotating cylinder 2023 are pivotally connected within the accommodating cavity 2017. Both the upper rotating cylinder 2023 and the lower rotating cylinder 2022 abut against the side walls of the base 2011 along the width direction of the base 2011. A receiving plate 2016 is disposed between the upper rotating cylinder 2023 and the lower rotating cylinder 2022. The upper rotating cylinder 2023 and the lower rotating cylinder 2022 can be configured to be connected to a polished rod within the accommodating cavity 2017 of the base 2011. A deep groove ball bearing is sleeved on the outer side of the polished rod, and the upper rotating cylinder 2023 or the lower rotating cylinder 2022 is sleeved on the deep groove ball bearing.

[0081] Furthermore, if Figure 7 and Figure 10 As shown, the upper plane of the receiving plate 2016 is higher than the upper plane of the first receiving hopper 2012, and a shift plate 2025 extending along its own width is provided in the middle of the receiving plate 2016. When the shift plate 2025 swings to above the first receiving hopper 2012, part of the waste will detach from the shift plate 2025 and enter the first receiving hopper 2012.

[0082] By providing the paddle 2025, larger waste materials that have not passed through the through hole 20161 can be brought to a position higher than the first receiving hopper 2012 by the paddle 2025. During the rotation of the cam 20181, the swinging direction of the swing arm 2019 changes, causing the receiving plate 2016 to stop and jerk. The large waste materials on the paddle 2025 fall by gravity into the first receiving hopper 2012. This arrangement allows the larger waste materials to reciprocate into the first hopper for further crushing until they can pass through the through hole 20161 and enter the second collecting portion 202 for further crushing.

[0083] Similarly, the receiving plate 2016 in the second collecting section 202 is provided with a through hole 20162 which is smaller in area than the through hole 20161 on the receiving plate 2016 of the first collecting section 201. Large-volume waste that cannot pass through the through hole 20162 needs to be crushed through a reciprocating cycle before it can fall into the first transmission section 3 for collection.

[0084] Preferably, if Figure 7 and Figure 10 As shown, the receiving plate 2016 is formed into an arc plate, and both ends of the arc plate are formed around the outside of the first receiving hopper 2012. The arc plate of this embodiment is a superior arc.

[0085] In addition, if Figures 4 and 5As shown, the first conveying section 3 includes a first frame 301, a first conveyor belt 302 mounted on the first frame 301, and a first driving section 303 for driving the first conveyor belt 302. The waste material crushed by the second collecting section 202 falls onto the first conveyor belt 302. In this embodiment, the first driving section 303 utilizes a rotary motor. The first conveyor belt 302 is mounted on a first driving shaft and a second driven shaft. Both the first driving shaft and the second driven shaft are provided with pulleys. The first driving section 303 drives the first driving shaft to rotate, which in turn drives the first driven shaft to rotate via the pulleys, thereby causing the first conveyor belt 302 to circulate, thereby transporting the fine waste particles crushed by the second collecting section 202 via the first conveying section 3.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
