[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Reference below Figure 1-Figure 13 The material receiving device according to the embodiment of the present invention is described. First, the waste buffer plate 411 is arranged on the inner side of the waste sampling port, so that after the material falls into the waste bin 41, the material can be prevented from quickly and massively overflowing. In addition, the dust suction component 5 effectively absorbs and discharges the dust near the identification device 2, reduces the influence of the dust on the identification device 2, improves the performance and reliability of the identification device 2, and thus improves the accuracy of the color sorter 100 in screening materials.

[0044] like Figure 1-13 As shown, a material receiving device according to an embodiment of the present invention includes: a device body 4, a finished product bin 42 and a waste bin 41 are formed in the device body 4, the device body 4 is provided with a feed port connected to both the finished product bin 42 and the waste bin 41, a waste sampling port connected to the waste bin 41 is provided on the side wall of the device body 4, the waste sampling port is provided with an openable and closable waste sampling door 414, a waste buffer plate 411 is also provided in the waste bin 41, and the waste buffer plate 411 is located between the waste sampling door 414 and the waste feeding space.

[0045] When the color sorter is working, the material receiving device is located below the sorting chamber. The materials passing through the sorting chamber can directly fall freely into the finished product bin 42, and the rejected materials will enter the waste bin 41 due to the change of the falling trajectory. The color sorter widely uses nozzles to reject materials, that is, the waste material feeding space is the space on the side of the nozzle facing the waste bin 41. Since the nozzle covers a large area, it is inevitable that the good materials nearby will be brought out when the bad materials are sprayed, resulting in the finished products being blown into the waste bin 41. In order to reduce the carry-out ratio, the materials in the waste bin 41 need to be sampled and tested during production, and the working parameters of the nozzle are adjusted when the carry-out ratio does not meet the requirements.

[0046] In the prior art, however, when the waste sampling door 414 is opened, materials will overflow from the waste sampling door 414 during the sampling process, affecting the on-site working environment and causing inaccurate sampling data. However, in the embodiment of the present invention, a waste buffer plate 411 is arranged on the inner side of the waste sampling port and in the waste bin 41. When the material falls into the inner side near the waste sampling door 414, the waste buffer plate 411 blocks and buffers the material to prevent the material from leaving the waste bin 41 directly from the waste sampling door 414.

[0047] Specific, combined Figure 1 and Figure 3As shown, the waste sampling door 414 is arranged on the side wall of the waste bin 41 away from the finished product bin 42, and the lower end of the waste sampling door 414 is hinged on the side wall of the waste bin 41 through the first chain 4141, so that it can be rotated outward to open, and the upper end of the waste sampling door 414 can be fixedly matched with the side wall of the waste bin 41 to realize the closure of the waste sampling door 414. The waste buffer plate 411 is arranged on the inner side of the waste bin 41, and at this time, the bottom of the waste buffer plate 411 can be higher than the bottom of the waste sampling port, that is, when the waste sampling door 414 is opened, due to the effect of the waste buffer plate 411, the waste will not flow out in large quantities, but the height difference between the bottom of the waste buffer plate 411 and the bottom of the waste sampling port can enable a small amount of waste to be taken out from the waste sampling port, thereby achieving orderly removal of waste.

[0048] Specifically, a lock buckle 4142 is rotatably provided on the side wall of the waste bin 41. When the waste sampling door 414 is in a closed state, the lock buckle 4142 can be rotated to a position that matches with the upper end surface of the waste sampling door 414 to lock the waste sampling door 414, thereby quickly and conveniently realizing the opening and closing operation of the waste sampling door 414. Of course, those skilled in the art can also realize the matching and fixing of the waste sampling door 414 and the waste bin 41 through other locking and fixing structures.

[0049] Therefore, in the embodiment of the present invention, a waste buffer plate 411 is disposed on the inner side of the waste sampling door 414 . When the waste sampling door 414 is opened outward, the waste buffer plate 411 can prevent waste from overflowing from the waste bin 41 .

[0050] In some embodiments, the waste buffer plate 411 includes an upper plate body 4111 and a lower plate body 4112 connected to each other, and the lower plate body 4112 is made of a flexible plate.

[0051] Reference Figure 4 As shown, the upper plate 4111 can be made of a harder material than the lower plate 4112. For example, the lower plate 4112 can be made of a silicone plate. When the operator takes samples from the lower side of the waste buffer plate 411, interference from the waste buffer plate 411 can be avoided, and the sharp material of the waste buffer plate 411 can be prevented from injuring the operator's hand. Figure 4 The pressure plate 4115 in the middle is fixed to ensure the strength of the silicone plate and prevent the silicone plate from being greatly deformed and affecting the blocking effect. In addition, the proportion of the upper plate body 4111 occupying the waste buffer plate 411 is greater than the proportion of the lower plate body 4112 occupying the waste buffer plate 411, that is, the lower part of the waste buffer plate 411 is close to the operator's hand, and a small amount of silicone material can be used here.

[0052] In some embodiments, side bend edges 4113 are formed on both sides of the waste buffer plate 411, and the side bend edges 4113 are respectively provided with a first connecting groove 4116 and a second connecting groove 4117 that cooperate with the side of the device body 4. In a fixed state, the first connecting groove 4116 is above the second connecting groove 4117, and the waste buffer plate 411 can be slidably adjusted relative to the device body 4 to release the first connecting groove 4116 from the device body 4, so that the waste buffer plate 411 is suitable for being hung on the device body 4 through the second connecting groove 4117.

[0053] In practice, the second connecting groove 4117 can be a closed groove body, and the waste buffer plate 411 can be connected to the device body 4 at the second connecting groove 4117. At the same time, the waste buffer plate 411 cooperates with the device body 4 at the position of the first connecting groove 4116. When the waste buffer plate 411 is slid and adjusted, the waste buffer plate 411 is disengaged from the device body 4 at the first connecting groove 4116. At this time, the waste buffer plate 411 only maintains an active connection with the device body 4 at the position of the second connecting groove 4117, which is equivalent to the waste buffer plate 411 moving downward and staggered with the position of the waste sampling door 414, so as to facilitate maintenance when the waste sampling door 414 is opened.

[0054] In some embodiments, the device body 4 is connected to a limit pin 417, the waste buffer plate 411 is locked and connected to the device body 4 at the second connecting groove 4117 through a locking stud 412 and a locking nut 413, and the waste buffer plate 411 is limited and supported on the limit pin 416 at the first connecting groove 4116, at least the first connecting groove 4116 has an upper opening structure, and the length of the first connecting groove 4116 is less than the length of the second connecting groove 4117.

[0055] Combination Figure 1 and Figure 4 As shown, when the waste buffer plate 411 is connected to the waste bin 41, the limiting pin 416 is connected to the first connection groove 4116 of the side bend 4113, the limiting pin 416 is located at the bottom of the first connection groove 4116, and the locking stud 412 and the locking nut 413 are connected to the second connection groove 4117. Generally, the locking stud 412 and the locking nut 413 lock the waste buffer plate 411 to the waste bin 41, and the limiting pin 416 limits the position of the waste buffer plate 411, that is, the initial state of the waste buffer plate 411 is as shown in FIG. Figure 1As shown; when the waste buffer plate 411 needs to be disassembled and the interior of the device body 4 needs to be maintained and debugged, the lower side of the waste buffer plate 411 is dragged by hand, and the locking nut 413 only needs to be loosened to loosen the locking nut 413 and the locking stud 412, and the waste buffer plate 411 can move downward. When the waste buffer plate 411 moves to the first connecting groove 4116 and leaves the limit pin 416, due to its own weight, the waste buffer plate 411 can be rotated clockwise downward along the locking stud 412 to the bottom, that is, the state of the waste buffer plate 411 is changed from Figure 1 The status changes to Figure 5 status.

[0056] Thus, the waste buffer plate 411 is connected to the waste bin 41 in this way, which is convenient for disassembly and installation. When repairing, it is not necessary to completely disassemble the waste buffer plate 411, so that it is more convenient to install and use it next time. It should be noted that this is only for the convenience of maintenance. Of course, in most cases, the waste buffer plate 411 is as follows Figure 1 state, that is, it plays the role of blocking materials.

[0057] In some embodiments, the finished product bin 42 is provided with a finished product sampling door 422, and the finished product sampling door 422 is suitable for rotating the lower end inward relative to the finished product bin 42 when opened, and is suitable for being locked by a locking member after closing.

[0058] Combination Figure 6-8 As shown, the locking piece is a hand-tightening handle, and the finished product bin 42 is provided with a first connecting ear 424 at the position where the finished product sampling door 422 is installed. The first connecting ear 424 is provided with an arc groove 4241, and the arc groove 4241 is provided with an A position and a B position. The finished product sampling door 422 is provided with a second connecting ear 4221, and a nut 4222 is provided at the second connecting ear 4221. When the finished product sampling door 422 is connected to the position of the finished product sampling port, the finished product sampling door 422 is also rotatably connected to the finished product bin 42 through the second chain 425. The hand-tightening handle 423 is provided with a connecting shaft, which is connected to the nut 4222 of the finished product sampling door 422 through the connecting shaft of the hand-tightening handle 423 or can be rotated relative to the nut 4222 and disengaged from the nut 4222, and the hand-tightening handle 423 is also connected to the second chain 425. When the hand-tightening handle 423 rotates, it drives the second chain 425 to rotate, so that the second chain 425 drives the finished product sampling door 422 to rotate open or close.

[0059] When the hand-tightening handle 423 is in position A, the connecting shaft of the hand-tightening handle 423 is connected and locked with the nut 4222 of the finished product sampling door 422. At this time, the finished product sampling door 422 is in a closed state. That is, when the connecting shaft of the hand-tightening handle 423 at the finished product sampling door 422 is locked with the nut 4222, the finished product sampling door 422 is also locked; when the connecting shaft of the hand-tightening handle 423 and the nut 4222 of the finished product sampling door 422 are loosened, the connecting shaft of the hand-tightening handle 423 can move along the arc groove 4241 to the B position, and the finished product sampling door 422 is closed. As the hand-twisted handle 423 moves, the second chain 425 can be driven to rotate, and the rotation of the second chain 425 can drive the finished product sampling door 422 to rotate toward the inside of the finished product bucket. By rotating the finished product sampling door 422 toward the inside, it can prevent the finished product sampling door 422 from being opened by the outward force applied to the finished product sampling door 422 after the finished material falls into the finished product bucket, thereby preventing the finished product sampling door 422 from being opened when the finished product sampling door 422 of the finished product bin 42 is opened outward for sampling.

[0060] In some embodiments, the material receiving device also includes a secondary bucket bin 44 and a return bin 43; the finished product bin 42 is located on one side of the waste bin 41, and the waste removal component 3 is arranged above the finished product bin 42. The return bin 43 is located on the side of the finished product bin 42 away from the waste bin 41. The secondary bucket bin 44 is provided with a feed port and a secondary bucket outlet 443. The secondary bucket bin 44 is used to receive the qualified and unqualified materials that deviate from the original track and cannot enter the finished product bin 42 due to the action of the spray valve of the waste removal component 3 through the feed port, and the secondary bucket outlet 443 is connected to the return bin 43.

[0061] In practice, continue to refer to Figure 1 As shown, a waste bin 41 is provided on one side of the finished product bin 42 and a return bin 43 is provided on the other side, and an auxiliary bin 44 is provided below the waste rejection member 3 and close to the finished product bin 42. Part of the auxiliary bin 44 is provided in the waste bin 41. The return bin 43 is used to collect materials that rebound during the screening process. In the process of the waste rejection member 3 rejecting waste, the surrounding materials are disturbed by the air flow and deviate from the original movement path, and some of the materials cannot enter the finished product bin 42. The auxiliary bin 44 is provided to receive materials that may be brought out by the exhaust gas of the spray valve of the waste rejection member 3. The structure of the auxiliary bin 44 is as shown in FIG. Fig. 9 and Fig.10 As shown, the auxiliary bucket bin 44 includes an auxiliary bucket cavity 442, which collects materials that deviate slightly from the original movement path. The materials may include finished materials or waste materials, and the finished materials account for a higher proportion. The finished materials and waste materials are discharged toward the return bin 43 and then discharged toward the return port 431. After discharge, the finished materials and waste materials can be sorted again.

[0062] like Fig.10As shown, the auxiliary bucket bin 44 is provided with an auxiliary bucket cavity 442, and an auxiliary bucket outlet 443 is provided along the side of the auxiliary bucket cavity 442 toward the return bin 43, and a first material guide plate 4421 and a second material guide plate 4422 are also provided in the auxiliary bucket cavity 442 of the auxiliary bucket bin 44. The first material guide plate 4421 and the second material guide plate 4422 are inclinedly arranged and connected at the top. The distance between the first material guide plate 4421 and the second material guide plate 4422 from the side close to the waste rejection part 3 to the side away from the waste rejection part 3 gradually increases. When the material falls into the auxiliary bucket bin 44 from the top of the auxiliary bucket bin 44, the first material guide plate 4421 and the second material guide plate 4422 guide the material toward the auxiliary bucket outlet 443, which is more conducive to the material flowing out toward the auxiliary bucket outlet 443.

[0063] Therefore, by setting the return bin 43 and the auxiliary bin 44, all materials can be received, and further screening on the next side can be performed to improve the purity of the material screening. Fig. 9 As shown, the auxiliary bucket 44 is also provided with an auxiliary bucket door installation opening, and the auxiliary bucket door 441 is as shown in FIG. Fig.11 As shown, the auxiliary bucket door 441 is provided with a fourth connecting ear 4411, and the fourth connecting ear 4411 is rotatably connected to the third connecting ear 444 of the auxiliary bucket bin 44 through a rotating shaft, and the downward extension length of the auxiliary bucket door 441 is greater than the height of the auxiliary bucket bin 44, so that when the auxiliary bucket door 441 is opened, it is convenient to open the auxiliary bucket door 441 by hand. The purpose of setting the auxiliary bucket door 441 is to facilitate the removal of materials in the auxiliary bucket bin 44 for debugging and analysis, and at the same time to facilitate the cleaning of the passage of the auxiliary bucket bin 44 to avoid blockage. The structural design of the auxiliary bucket door 441 is simple, and it is convenient to open and maintain.

[0064] In some embodiments, the material receiving device also includes a dust suction component 5, a dust suction inlet 512 of the dust suction component 5 is arranged at the upper end of the waste bin 41, and a dust suction channel 53 connected to the dust suction inlet 512 is formed between the waste buffer plate 411 and the side of the waste bin 41.

[0065] Reference Figure 1 As shown, a mixture of unqualified materials and qualified materials is transported to the feed port, and the identification device 2 is connected to the waste bin 41, and the identification device 2 analyzes the color of the materials. A waste rejection part 3 is provided on one side of the feed port, and the identification device 2 transmits the screening result to the control system, and the control system controls the waste rejection part 3 to blow the waste into the waste bin 41. After the materials are identified by the identification device 2, they are sorted by the waste rejection part 3. The waste rejection part 3 blows and rejects the waste, which will cause more dust. At this time, the dust will affect the identification and judgment effect of the identification device 2.

[0066] A dust suction component 5 is installed on one side of the identification device 2. The dust suction component 5 is provided with a connecting frame 514 and is connected to the dust suction component 5 through the connecting frame 514 and the connecting piece. Dust is sucked to the dust suction inlet 512 of the dust suction component 5 along the dust suction channel 53 between the waste buffer plate 411 and the side of the waste bin 41. The dust suction component 5 can extract the gas and raised dust sprayed into the waste bin 41 by the waste removal component 3, so that the identification device 2 can more accurately take pictures and samples the materials at the waste removal component 3, thereby improving the accuracy of material screening.

[0067] Furthermore, the dust suction inlet 512 may be provided in a plurality of ways, such as Fig.12 As shown, the dust suction component 5 is provided with a plurality of dust suction inlets 512 distributed at intervals. For example, for a channel type color sorter, a dust suction inlet 512 may be provided corresponding to each channel interval. A dust suction channel 53 is defined between the waste buffer plate 411 and the side wall of the waste bin 41 and / or the waste sampling door 414. Dust passes through the dust suction channel 53 and reaches the plurality of dust suction inlets 512, thereby improving the dust absorption efficiency so that the identification device 2 can identify the material more accurately.

[0068] Reference Figure 2 As shown, a plurality of device bodies 4 may be provided at the bottom of the distribution direction of the plurality of dust suction inlets 512, with gaps left between the plurality of device bodies 4 to facilitate maintenance and operation of a certain device body 4 between adjacent device bodies 4, and each device body 4 is provided with a waste removal component 3, and the plurality of device bodies 4 share one dust suction component 5, and each dust suction inlet 512 corresponds to one device body 4, so that one dust suction component 5 can absorb dust in a plurality of material receiving devices at the same time.

[0069] In some embodiments, the dust suction component 5 is provided with a dust suction chamber, and the dust suction component 5 is provided with at least one air suction port 56 , and the air suction port 56 is connected to a dust removal fan.

[0070] Reference Fig.12 As shown, the dust collection component 5 is provided with a dust collection chamber. When the dust is absorbed into the dust collection chamber of the dust collection component 5, an exhaust port 56 is provided at one or both ends of the dust collection component 5. A dust removal fan is installed at the exhaust port 56 to make the dust removal fan work and take away the dust in the waste bin 41.

[0071] Of course, the air outlet 56 can also be set at other positions of the dust collection component 5, as long as a dust removal fan can be installed, and the dust can be sucked into the dust collection chamber of the dust collection component 5 and sucked out from the dust collection chamber by the dust removal fan. If there are a large number of dust collection channels 53, in order to improve the uniformity of the air volume of each dust collection channel 53, the air outlet 56 can also be designed in the middle position of the dust collection component 5.

[0072] In some embodiments, the dust collection assembly 5 is provided with a cleaning port 511, and a dust collection door cover 52 is connected to the cleaning port 511 via a fastener, and the dust collection door cover 52 is suitable for rotating relative to the cleaning port 511 toward the outside of the dust collection assembly 5 after the fastener is loosened.

[0073] In practice, the cleaning port 511 can be arranged in the middle of the dust collection component 5, and a dust collection door cover 52 is installed at the cleaning port 511. When the handle 521 is pulled to open the dust collection door cover 52, the blockage inside the dust collection chamber can be cleaned, thereby ensuring that the dust collection component 5 can clean dust smoothly and efficiently. Fig.12 As shown, door cover connecting holes 513 are provided on both sides of the cleaning port 511, and hand screws 55 are connected to the door cover connecting holes 513, and the fasteners are hand screws 55. During normal vacuuming, the dust collection door cover 52 remains in a fixed connection state at the cleaning port 511. When the dust collection door cover 52 needs to be opened, the hand screws 55 are loosened, and the dust collection door cover 52 can be rotated and lifted toward the outside of the dust collection component 5, so as to open the dust collection door cover 52, but at the same time the dust collection door cover 52 will not be completely disassembled, so that the dust collection door cover 52 can be conveniently fixed after cleaning; by setting the dust collection door cover 52, impurities in the dust collection chamber of the dust collection component 5 can be cleaned in time to avoid blockage in the dust collection chamber and ensure smooth dust collection.

[0074] In some embodiments, the dust suction component 5 is constructed as a dust suction circular tube, which includes a tube body 51 and an end cover 515 , and the end cover 515 and the tube body 51 are connected with a rounded structure transitionally.

[0075] Among them, by setting the dust collection component 5 as a dust collection circular tube, and the transition connection between the tube body 51 and the end cover 515 is also a rounded structure, the dust collection component 5 with a circular cavity can reduce the dead corners inside the dust collection cavity, reduce the settlement of dust in the dust collection cavity, and improve the overall dust removal efficiency.

[0076] In some embodiments, the dust collection component 5 is installed at the upper end of the waste bin 41, and the outer side of the dust collection component 5 is covered with a flexible cushion layer.

[0077] The design of the flexible cushion layer can not only achieve the sealing of the dust collection component 5 and other structures such as the waste bin 41, but also achieve the buffering and supporting effect of the dust collection component 5. At the same time, when the dust collection component 5 is connected to the identification device 2, it also has a buffering effect on the identification device 2. When the dust collection component 5 is collecting dust, it will vibrate and affect the recognition accuracy of the identification device 2. Therefore, a flexible cushion layer is arranged on the periphery of the dust collection component 5 to buffer the identification device 2. Of course, the sealing with the waste bin 41 is maintained.

[0078] In some embodiments, the dust collection assembly 5 is provided with a dust collection baffle that cooperates with the waste buffer plate 411 near the dust collection inlet 512, and the dust collection baffle includes a bent baffle flange 54, and a top folded edge 4114 is formed at the upper end of the waste buffer plate 411, and at least one side of the baffle flange 54 facing the waste buffer plate 411 is covered with a flexible cushion layer, and when the waste buffer plate 411 is fixed to the waste bin, the baffle flange 54 and the top folded edge 4114 press the flexible cushion layer.

[0079] In practice, the flexible cushion layer includes a first flexible cotton 6, a second flexible cotton 7 and a third flexible cotton 8 which are circumferentially arranged at different positions. The periphery of the dust collection component 5 in contact with the waste bin 41 is provided with a third flexible cotton 8, the periphery in contact with the identification device 2 is provided with a first flexible cotton 6, and the periphery in contact with the waste buffer plate 411 is provided with a second flexible cotton 7.

[0080] Reference Fig.13 As shown, the first flexible cotton 6 is pasted on the tangent line of the dust collection component 5 of the circular tube structure. After the dust collection component 5 is fixed to the identification device 2, the first flexible cotton 6 can better cooperate with the dust collection component 5, and at the same time, the dust collection component 5 and the identification device 2 can be better buffered to reduce the impact of the vibration of the dust collection component 5 on the identification device 2, thereby improving the recognition accuracy of the identification device 2; in addition, a top folding edge 4114 is further provided at one end of the waste buffer plate 411 connected to the dust collection component 5, that is, the top folding edge 4114 is located at the top of the waste buffer plate 411 and is at the two adjacent side folding edges 4113, the dust collection component 5 is provided with a dust collection baffle, and the dust collection baffle includes a baffle flange 54. The baffle flange 54 of the dust collection component 5 and the top folded edge 4114 of the waste buffer plate 411 are sealed by the second flexible cotton 7, and the seal between the baffle flange 54 and the top side 4114 can increase the sealing area, facilitate sealing, and ensure that the dust in the waste bin 41 is sucked into the dust collection chamber as much as possible, while increasing the supporting performance of the dust collection component 5 after being connected to the waste buffer plate 411; in addition, the third flexible cotton 8 is arranged between the dust collection component 5 and the waste bin 41 for sealing.

[0081] When the waste rejection piece 3 is pushed into the set position, the first flexible cotton 6, the second flexible cotton 7 and the third flexible cotton 8 are all rubber-plastic polyethylene cotton with a high foaming coefficient. The rubber-plastic polyethylene cotton with a high foaming coefficient has the advantages of being green and environmentally friendly, reducing noise and vibration, having a long service life and good fire resistance.

[0082] The embodiment of the present invention also discloses a color sorter, comprising a feeding device 1, a waste rejection part 3, an identification device 2 and the above-mentioned material receiving device, that is, the material is transported to the position of the waste rejection part 3 by the feeding device 1, and the identification device 2 takes a photo of the material at the position of the waste rejection part 3 to identify the material, and the waste rejection part 3 then rejects the corresponding waste and rejects it into the waste bin 41, thereby achieving the effect of material screening.
