[0029] The material screening device is a key material separation device, and the existing design has shown its limitations in coping with the increasing production capacity demand and more stringent quality standards, and it is difficult to meet these increasing demands. After the separation of the material in the traditional material screening device design, the material texture of the material itself affects the material, and part of the material is screened due to its gravity and other factors, so that the impact force of the falling material is large, which causes the material to collide with the structure on the material screening device, and the material is easily damaged to a certain extent, which is not conducive to long-term use and has poor reliability.
[0030] The utility model provides a kind of unloading buffer device 100.

[0032] The blanking buffer device 100 of the utility model, by adopting first casing 1 and being equipped with feed inlet 14 on first casing 1, material can enter first channel 11 from feed inlet 14, and screening mechanism 2 is arranged at the discharge port position of first casing 1, so that the material can be further screened, and the material that does not meet the specification size can be more effectively screened out, thereby improving the quality of the material obtained after screening, by arranging two buffer plates in the first channel 11, after the material enters the first channel 11 after screening, it will first contact the first buffer plate 16a, because the plate is downwardly inclined, the falling speed of the material will be slowed down and guided to the second buffer plate 16b, and after further slowing down, it falls from the discharge port to the slide screen 22 for further screening, the two buffer plates can significantly disperse part of the impact force generated during the falling of the material, effectively reducing the falling difference of the material, thereby avoiding damage to the material due to violent impact during falling, and the reliability is better.
[0033] In an embodiment, the screening mechanism 2 includes a second casing 21 and a slide screen 22, the second casing 21 is connected with the first casing 1, the second casing 21 forms a second channel communicated with the first channel 11, the second casing 21 is provided with a first outlet 211 and a second outlet 212 communicated with the second channel, the first outlet 211 is located below the blanking port 15, and the second outlet 212 is located below a side of the first outlet 211 along the horizontal direction, the slide screen 22 is arranged at the first outlet 211, and the slide screen 22 includes a mounting end 221 close to the first side 12 and a discharge end 222 away from the first side 12, the discharge end 222 is arranged towards the second outlet 212, the slide screen 22 is downwardly inclined from the mounting end 221 to the discharge end 222, and the slide screen 22 is used to screen the material entering the second channel from the blanking port 15.
[0034] It can be understood that the second housing 21 forms a second channel in communication with the first channel 11, and is provided with a first outlet 211 and a second outlet 212. After being screened by the slide screen 22, the oversize material is discharged from the second outlet 212, and the undersize material is discharged from the first outlet 211, thereby facilitating the collection of different specifications of materials. The slide screen 22 is downwardly inclined from the mounting end 221 to the discharge end 222. This design can effectively guide the material to slide / roll along the surface of the slide screen 22, and at the same time, the gravity of the material itself can assist the material to slide along the surface of the slide screen 22, thereby facilitating the separation of the material. The material adjusts its own posture passively in the process of sliding or rolling, so as to achieve the best screening effect. In addition, it also prevents the material from piling up on the slide screen 22, thereby improving the screening efficiency.
[0035] It should be noted that the slide screen 22 can adopt the slide screen 22 in the prior art, which has a screen mesh. The oversize material is the material that cannot pass through the screen mesh, and the undersize material is the material that can pass through the screen mesh. The material that passes through the screen mesh is directly discharged from the first outlet 211, and the material that cannot pass through the screen mesh slides / rolls along the top surface of the screen mesh, thereby being discharged from the second outlet 212.
[0036] Specifically, the slide screen 22 completely covers the first outlet 211, thereby preventing the material from falling out of the gap between the slide screen 22 and the first outlet 211.
[0037] In an embodiment, the screening mechanism 2 further comprises a guide frame 23. One end of the guide frame 23 is connected with the second housing 21. The guide frame 23 is provided with a first chute in communication with the first outlet 211. The first chute is downwardly inclined from the end close to the first outlet 211 to the end away from the first outlet 211.
[0038] It can be understood that the guide frame 23 and the first chute thereon provide a smooth transition path for the material discharged from the first outlet 211 of the slide screen 22. The downwardly inclined chute can ensure that the material moves on the first chute under the influence of gravity, thereby avoiding the material from being concentrated and piled up on the first chute. The guide frame 23 also prevents the material from being scattered and falling out of the first outlet 211.
[0039] In an embodiment, a transparent window is arranged at the top of the guide frame 23 and close to the first outlet 211.
[0040] It can be understood that the transparent window arranged at the top of the guide frame 23 and close to the first outlet 211 enables the worker to directly observe the process of the material from the slide screen 22 to the first outlet 211 into the first chute, and can timely discover abnormalities such as blockage of the slide screen 22 and blockage of the first chute, thereby facilitating the timely handling of abnormal conditions.
[0041] In yet another embodiment, the entire guide frame 23 is made of transparent material.
[0042] In an embodiment, the outer side of the guide frame 23 away from the first chute is provided with a vibration driving member 25 for driving the guide frame 23 to vibrate. It can be understood that the vibration driving member 25 can make the guide frame 23 vibrate at high frequency, effectively preventing the material from being blocked in the first chute; the vibration can accelerate the speed of the material passing through the first chute, reduce the residence time of the material in the first chute, thereby improving the separation efficiency of the material.
[0043] Further, the slide screen 22 is also connected with the guide frame 23; when the guide frame 23 is driven to vibrate by the vibration driving member 25, the guide frame 23 can also drive the slide screen 22 to vibrate, thereby accelerating the speed of the slide screen 22 screening the material, further improving the screening efficiency of the material.
[0044] It should be noted that the vibration driving member 25 can be a vibration exciter or a vibration motor in the prior art, etc.
[0045] In an embodiment, the screening mechanism 2 further comprises a swing frame 24, one end of the swing frame 24 is rotationally connected with the second housing 21, and the swing frame 24 is provided with a second chute in communication with the second outlet 212. It can be understood that the swing frame 24 is rotationally connected with the second housing 21, so that the second chute can be adjusted in angle or position as needed, which makes it possible to flexibly guide and control the direction of the material, and is more flexible.
[0046] In an embodiment, the end of the overhanging end 162 of the second buffer plate 16b is vertically corresponding with the end of the discharge end 222. This makes the second buffer plate 16b and the slide screen 22 have no interval distance in the vertical direction, and the material buffered by the second buffer plate 16b can all fall into the slide screen 22 for screening, preventing the situation of missing screening, and having better reliability.
[0047] In yet another embodiment, part of the second buffer plate 16b and part of the slide screen 22 are vertically overlapped. This setting can further ensure that the material falls accurately into the slide screen 22, and in addition, it can also cope with more sudden situations, such as the trajectory deviation of the material caused by the collision between the materials, and has better reliability.
[0048] In an embodiment, the first channel 11 is further provided with a buffer pad 17, the buffer pad 17 is installed on the second side 13, and the buffer pad 17 is located above the second buffer plate 16b and corresponds to the position of the overhanging end 162 of the first buffer plate 16a.
[0049] It can be understood that by setting the buffer pad 17, when the material falls from the first buffer plate 16a, the material is prevented from directly colliding with the second side 13, and the buffer pad 17 also slows down the kinetic energy of the material when falling, which can effectively reduce the impact force of the material, avoid damaging the first shell 1 or causing the material to be damaged, prolong the service life of the first shell 1, ensure the material quality, and better reliability.
[0050] Further, the position corresponding to the second buffer plate 16b on the first side 12 is also provided with a buffer pad, and the inner wall opposite to the slide screen 22 in the second channel is also provided with a buffer pad, which can be used to reduce the impact force of the material colliding with the first shell 1 or the second shell 2, and better reliability.
[0051] Specifically, the buffer pad 17 can adopt a rubber pad, a silica gel pad and the like in the prior art.
[0052] In an embodiment, the top of each buffer plate is provided with an elastic buffer layer. It can be understood that the elastic buffer layer can reduce the impact force of the material colliding on each buffer plate, maintain the stability of the material, avoid damage to the material or the buffer plate, and have good reliability.
[0053] Specifically, the elastic buffer layer can also adopt a rubber pad, a silica gel pad and the like in the prior art.
[0054] The utility model also proposes a kind of material screening equipment 200, material screening equipment 200 is provided with the above-mentioned one kind of unloading buffer device 100, and feed inlet 14 is communicated with the discharge port of material screening equipment 200.The specific structure of the unloading buffer device 100 refers to the above-mentioned embodiment, since the main material screening equipment 200 adopts all technical solutions of the above-mentioned all embodiments, at least has all beneficial effects brought by the technical solutions of the above-mentioned embodiment, and here is not repeated.
[0055] Among them, material screening equipment 200 can carry out the first screening to material, and the screening mechanism 2 arranged on unloading buffer device 100 can carry out secondary screening, and the material discharged from first outlet 211 after screening can be returned to material screening equipment 200 to carry out screening again, and the material discharged from second outlet 212 can be directly collected, significantly improve the screening effect of material, and better reliability.
