[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0026] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0027] In order to solve the technical problem in the prior art that some materials are difficult to collect at the receiving port, causing clogging of the mesh holes in some areas, the present application provides a screen structure with a material collecting function, which can realize the collection of powder particles when the powder particles are too large to be screened out by setting a receiving tray structure, thereby avoiding the clogging of the mesh holes on the screen and affecting the screening efficiency. It is beneficial to the rapid recovery of materials that do not meet the specifications and the subsequent secondary processing and reuse, and is also beneficial to improving the screening efficiency.

[0028] Figure 1 A screen structure with a material collecting function is provided in the embodiment of the present application. It cooperates with a high-sealing screening machine to realize powder screening and material collecting, including a collecting tray structure 1, a screen 2 and a collecting part 3. The screen 2 is arranged in the middle position of the collecting tray structure 1, and the collecting part 3 is arranged at the edge of the collecting tray 5. When the high-sealing screening machine is working, the powder material falls and then moves around the screen 2. Most of the materials with a size smaller than the aperture of the screen 2 are screened through the screen 2, and the remaining small part of the unscreened materials and the materials with a size larger than the aperture of the screen 2 move to the periphery of the screen 2 due to the movement of the screening machine. The materials reaching the periphery of the screen 2 are collected by the collecting part 3 due to the existence of the collecting part 3 for subsequent secondary processing and screening operations. Some of the materials that are blocked and not collected by the edge of the collecting part 3 will be transported to the collecting part 3 again under the movement of the subsequent screening machine to realize material collection.

[0029] See also Figure 2 , an opening 4 matching the shape and size of the screen 2 is provided in the middle position of the receiving tray structure 1, and the screen 2 is accommodated in the opening 4 and is arranged flush with the opening 4. The screen 2 is arranged in the middle position of the receiving tray structure 1, so that, driven by the sifting machine, the material will move to the outside of the screen 2, and the arrangement of the receiving tray structure 1 realizes the natural recovery of the material, avoiding the situation that the screen 2 is arranged at one end of the receiving tray structure 1, causing part of the material to stay at the screen 2 for a long time and causing the mesh to be blocked; the screen 2 and the opening 4 of the receiving tray structure 1 are arranged flush, which is conducive to the smooth movement of the material to the receiving tray structure 1, avoiding the height difference affecting the movement of the material, and the powder is more likely to enter the gap between the two. Preferably, the shape of the opening 4 is circular, square or elliptical, which has the advantages of simple structure and convenience, including but not limited to this, and can also be set to an angle, trapezoid and other shapes, which can be set according to actual conditions.

[0030] Please continue reading Figure 2The receiving tray structure 1 includes a tray 5 and a baffle plate 6, which is arranged around the tray 5 and partially protrudes from the tray 5. The arrangement of the baffle plate 6 increases the stability of the overall structure and reduces the possibility of the structure becoming loose after being used for a period of time. At the same time, the structural design of partially protruding from the tray 5 can also prevent the material moving to the edge of the tray 5 from falling, which is conducive to avoiding material waste and saving costs.

[0031] Please continue reading Figure 1 A discharge port 7 is provided at the edge of the tray 5. In this way, when the sifter is working, the powder that cannot be sieved out from the screen 2 is continuously moved from the screen 2 to the tray 5, and continuously moves toward the edge of the tray 5. Through the discharge port 7 located at the edge, the powder can fall in and be subsequently collected. Preferably, the discharge port 7 is tangent to the inner side of the baffle plate 6, which is conducive to avoiding the possibility that the powder that always moves at the edge of the tray 5 cannot fall in, and improves the completeness of powder collection.

[0032] Please continue reading Figure 2 The receiving part 3 collects the powder and transfers the powder to the external recovery structure through the discharge port 7 for subsequent secondary processing and reuse. Specifically, the receiving part 3 includes a curved baffle plate 8 and a discharge pipe 9. The curved baffle plate 8 is arranged on one side of the material tray 5 and is arranged at the discharge port 7. The curved baffle plate 8 is arranged at the edge of the material tray 5 and one end is in contact with the baffle plate 6, and the other end is spaced from the baffle plate 6, that is, one end is used for the entry of powder, and the other end is used to prevent the powder from moving out. The discharge port 7 is arranged between the curved baffle plate 8 and the baffle plate 6. The curved baffle plate 8 is used for the powder to enter the curved baffle plate 8 and the baffle plate 6 during the movement. The powder at the edge of the tray 5 is gathered together so that most of the powder enters between the curved baffle plate 8 and the baffle plate 6 during the movement, so that the powder finally moves therein and then falls into the discharge port 7, avoiding the situation where the powder is not easy to fall into the discharge port 7 due to lack of constraints; the discharge pipe 9 is arranged on the side of the tray 5 away from the curved baffle plate 8, and the discharge pipe 9 is connected to the discharge port 7. The arrangement of the discharge pipe 9 allows the powder falling from the discharge port 7 to be guided so as to enter the subsequent recovery structure. Preferably, the curved baffle plate 8 is welded to the tray 5, and has the advantages that it is not easy to have gaps at the connection, the powder is not easy to get stuck and leak out, and the connection is relatively stable.

[0033] Please continue reading Figure 2The curved baffle plate 8 of the present application includes a first curved plate 10 and a second curved plate 11, one end of the first curved plate 10 is fixedly connected to one end of the second curved plate 11, the opening direction of the arched protrusion of the first curved plate 10 is away from the center of the material tray 5, the opening direction of the arched protrusion of the second curved plate 11 is toward the center of the material tray 5, and the other end of the first curved plate 10 is in contact with the enclosure plate 6. The opening direction of the arched protrusion of the first curved plate 10 is away from the center of the material tray 5, so that the curved baffle plate 8 can gather more powder, providing a larger movement space for the powder to finally move into the material inlet and outlet 7; the opening direction of the arched protrusion of the second curved plate 11 is toward the center of the material tray 5, providing a relatively small feed inlet, so that the powder entering the range of the curved baffle plate 8 is not easy to move out, thereby improving the gathering effect. Preferably, the tangent of the first curved plate 10 corresponding to the connection end with the second curved plate 11 and the tangent of the second curved plate 11 corresponding to the connection end with the first curved plate 10 coincide with each other, that is, the two are smoothly connected, which reduces the possibility of powder being blocked when passing through, and reduces the possibility of powder agglomerating into blocks to affect discharge and increase the difficulty of cleaning.
