Any prior art methods, equipment, and materials similar or equivalent to those described in the examples of this utility model may also be used to implement this utility model.

[0022] In the prior art, a pellet screening device can often only screen pellets within a single size range and cannot simultaneously screen pellets of different sizes. Such a device has low screening efficiency and poor practicality.

[0023] An embodiment of the present application provides a pill screening device, comprising a frame 1, a feed bin 2, a vibrating mechanism 3, and a screening mechanism 4 for screening pills of different sizes, wherein the feed bin 2 is mounted on the frame 1, the screening mechanism 4 is mounted on the frame 1, and is arranged below the feed bin 2, for receiving the falling material from the feed bin 2, the screening mechanism 4 comprises a plurality of box units 41 spliced in sequence along the length direction of the screening mechanism 4, each box is provided with a screen 42 connected to the inner cavity of the box unit 41, the mesh sizes of the screens 42 on two adjacent boxes are different, the plurality of screens 42 are arranged obliquely along the length direction of the screening mechanism 4, and the highest screen 42 is arranged corresponding to the discharge port of the feed bin 2.

[0024] In the embodiment of the present application, by providing a plurality of screens 42 with different mesh sizes on the screening mechanism 4, pellets of different sizes can be screened out, thereby classifying the pellets of different sizes and improving screening efficiency. The device uses a vibrating mechanism 3 to drive the screening mechanism 4 to vibrate for screening, resulting in a high degree of automation, which can reduce production costs and improve production efficiency.

[0025] In one embodiment, the upper surface of the screening mechanism 4 is higher at one end close to the feed bin 2 and lower at one end away from the feed bin 2 .

[0026] In the embodiment of the present application, the height of the upper surface of the screening mechanism 4 is higher at one end close to the feed bin 2 and lower at the other end away from the feed bin 2. This allows the pills to move smoothly from the high point to the low point of the screening mechanism 4, allowing the pills to pass through screens 42 of different specifications, thereby smoothly screening out pills of different sizes.

[0027] In one embodiment, the screen 42 is divided into a first screen 421, a second screen 422 and a third screen 423 according to the mesh specifications from small to large. The first screen 421, the second screen 422 and the third screen 423 are arranged in sequence from high to low according to height on the upper surface of the screening mechanism 4.

[0028] In the embodiment of the present application, the mesh size of the first screen 421 is the smallest, and the mesh size of the third screen 423 is the largest. The first screen 421 is set at the highest point on the upper surface of the screening mechanism 4. Along the moving direction of the pills, the lower the height, the larger the mesh size. In this way, pills of different sizes can be screened out in turn, reducing the mixing of pills of different sizes and facilitating the classification and collection of pills.

[0029] In one embodiment, the first screen 421 , the second screen 422 and the third screen 423 are all in plurality, and the screens 42 of the same specification are stacked longitudinally.

[0030] It should be explained that the screens 42 are stacked in the longitudinal direction, which means that the screens 42 are stacked in a direction perpendicular to the upper surface of the screening mechanism 4 .

[0031] In the embodiment of the present application, there are multiple screens 42, and screens 42 of the same specifications are stacked longitudinally. This enables the device to screen pills of different sizes more accurately, reduces errors in the screening process, and improves work efficiency.

[0032] It should be noted that the arrangement of the screen 42 is not limited to the one described above. For example, the screen 42 can also be arranged individually.

[0033] In one embodiment, each box unit 41 has a first passage 43 below the inner cavity thereof for the pellets to pass through.

[0034] It should be explained that the first channel 43 is communicated with the inner cavity of the box unit 41 , and the first channel 43 is an inclined channel.

[0035] In the embodiment of the present application, a first channel 43 is provided below the inner cavity of the box unit 41, so that the pellets screened into the inner cavity can leave the inner cavity along the channel, thereby reducing the accumulation of pellets in the box unit 41, enabling the device to work continuously and improving work efficiency.

[0036] In one embodiment, there are multiple first channels 43 , and the outlets of adjacent first channels 43 are cross-arranged along two sides of the screening mechanism 4 box.

[0037] It should be explained that the outlets of adjacent first channels 43 are cross-arranged along both sides of the screening mechanism 4 box, that is, in every two adjacent first channels 43, the outlet of one first channel 43 is set on one side of the box, and the outlet of the other first channel 43 is set on the other side of the box, and the outlets of the two adjacent first channels 43 are respectively set on different sides of the box.

[0038] In this embodiment, the outlets of adjacent channels are arranged crosswise along the sides of the screening mechanism 4. This facilitates the collection of pellets of different specifications and reduces the possibility of mixing pellets of different specifications. Placing the outlets of the first channel 43 on both sides of the box also provides more space for the receiving vehicle 5, allowing more pellets to be collected at a time.

[0039] In one embodiment, a material receiving trolley 5 for receiving the pellets is provided below the first channel 43 .

[0040] It should be explained that there are multiple material receiving carts 5 , and each material receiving cart 5 is placed under a corresponding first channel 43 .

[0041] In the embodiment of the present application, a material receiving vehicle 5 is provided under the channel, which can collect the screened pellets in time to facilitate the classification of the pellets.

[0042] In one embodiment, the screening box further comprises a debris bin 44 , the debris bin 44 comprises a second passage 45 , and the second passage 45 leads vertically to the material receiving vehicle 5 below.

[0043] It should be explained that some shot materials are too large to be directly put into the shot blasting machine for use. In this case, it is necessary to separate such shot materials separately.

[0044] In the embodiment of the present application, a debris bin 44 is provided to receive oversized pellets, which can separate such pellets from the screened pellets and separate unsuitable pellets for separate collection. This can improve subsequent work efficiency and uniformly recycle oversized pellets, thereby reducing production costs.

[0045] In one embodiment, the frame 1 has an escape opening 12 for the first passage 43 and the second passage 45 to pass through.

[0046] In the embodiment of the present application, the frame 1 has an avoidance opening 12 for the first channel 43 and the second channel 45 to pass through, so that the first channel 43 and the second channel 45 can smoothly pass through the frame 1 to transport the shot material to the material receiving vehicle 5, and the first channel 43 and the second channel 45 can be more firmly installed on the frame 1, reducing the vibration of the first channel 43 and the second channel 45 and improving the efficiency of material receiving.

[0047] In one embodiment, two spring seats 6 are connected to the box walls on both sides of the screening mechanism 4. A spring is installed in each spring seat 6 for resetting the screening mechanism 4. One end of the spring seat 6 is connected to the box wall of the screening mechanism 4. The frame 1 has a mounting seat 11 corresponding to the position of the spring seat 6, and the other end of the spring seat 6 is connected to the mounting seat 11.

[0048] It should be explained that the connection between the spring seat 6 and the box wall of the screening mechanism 4 is preferably welding.

[0049] In the embodiment of the present application, a spring is provided between the screening mechanism 4 and the frame 1, so that the screening mechanism 4 can be smoothly reset after vibration, and the vibration of the screening mechanism 4 can be adjusted within a relatively stable range.

[0050] The above technical solutions of the present invention are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
