[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the fastener screening device provided by this utility model. Figure 1 ;

[0026] Figure 4 This is a schematic diagram of the auxiliary structure and the sorting and unloading section in this utility model;

[0027] Figure 5 This is a schematic diagram of the sorting and feeding section and the adjustment section in this utility model.

[0028] The fastener screening device includes: a first screening section 1 and a second screening section 2. The first screening section 1 includes a support 3, a screening box 4 is provided on the support 3, a preliminary screening section 5 is provided on the screening box 4, a collection box 6 is slidably connected to the lower part of the screening box 4, and a discharge channel 7 is fixedly connected to the side of the screening box 4 near the second screening section 2. The second screening section 2 includes a vibrating feeder body 8, a spiral feeding channel 9 is provided on the inner side of the vibrating feeder body 8, and an auxiliary structure 10, a sorting and unloading section 11, and an adjustment section 12 are provided on the upper part of the vibrating feeder body 8.

[0029] Fasteners first enter the screening box 4 of the first screening section 1. After being vibrated and screened by the preliminary screening section 5, smaller fasteners such as nuts fall into the collection box 6, while larger fasteners such as bolts enter the second screening section 2 through the discharge channel 7. In the second screening section 2, the vibrating feeder body 8 causes the fasteners to rise in an orderly manner along the spiral feeding channel 9. They are then guided to the classification and unloading section 11 by the auxiliary structure 10. Under the action of gravity and related structures, the fasteners slide along the inclined plane. The size of the unloading notch 115 is adjusted by the adjustment section 12 to achieve sequential screening and classification of fasteners of various specifications.

[0030] The screening box 4 includes a box body 41 and a screening plate 44. The upper part of the box body 41 is rotatably connected to a top cover 42. The top cover 42 is provided with a feed inlet 43. The inner wall of the box body 41 is rotatably connected to a rotating seat 45. The screening plate 44 is fixedly connected to the rotating seat 45. A spring 46 is fixedly connected to the screening plate 44.

[0031] The top cover 42 is rotatably connected to the upper part of the box 41, making it easy to open the box 41 for internal maintenance and cleaning, and preventing the screening plate 44 from becoming clogged after long-term use, which would lead to a decrease in screening efficiency. The rotating seat 45 enables the screening plate 44 to rotate, and works with the preliminary screening part 5 to drive the screening plate 44 to perform vibration screening. The spring 46 plays a buffering and resetting role when the screening plate 44 vibrates.

[0032] The preliminary screening unit 5 includes a driving component 51 and a lifting block 54. The output end of the driving component 51 is provided with a rotating shaft 52, and the end of the rotating shaft 52 is fixedly connected to a cam 53. The lifting block 54 is set on the screening plate 44 at a position corresponding to the cam 53.

[0033] When the drive unit 51 is working, it drives the rotating shaft 52 to rotate, which in turn causes the cam 53 to rotate. During the rotation of the cam 53, it will lift the lifting block 54, thereby causing the screening plate 44 to vibrate up and down. Through vibration, the fasteners are initially screened, and small fasteners such as nuts are screened out.

[0034] The auxiliary structure 10 includes an annular retaining edge 101 and a transfer slope 104. The annular retaining edge 101 has a discharge port 102. One end of the annular retaining edge 101 is provided with a baffle 103. The two sides of the transfer slope 104 are fixedly connected to the two ends of the annular retaining edge 101. The transfer slope 104 is located below the discharge port 102.

[0035] The annular retaining edge 101 prevents fasteners from falling off the edge during conveying. The discharge port 102 is used for the output of fasteners. The shape of the baffle 103 can be changed according to actual needs to block and orient the fasteners, preventing them from accumulating excessively at the discharge port 102 and affecting screening. The transfer slope 104 is located below the discharge port 102 to smoothly transfer the fasteners to the sorting and unloading section 11.

[0036] The sorting and unloading section 11 includes an inclined annular plate 111, with a starting end 112 and a stopping end 113 at its two ends. The height of the stopping end 113 is lower than that of the starting end 112. A fixing rod 114 is provided below the inclined annular plate 111, and the other end of the fixing rod 114 is fixedly connected to the vibrating feeder body 8.

[0037] There is a height difference between the two ends of the inclined annular plate 111, with the starting end 112 being higher than the ending end 113. By utilizing gravity and the blocking and positioning effect of the baffle 103, the heads of fasteners such as bolts are stuck on the upper part of the inclined annular plate 111 and slide automatically along the inclined annular plate 111. The fixing rod 114 fixes the inclined annular plate 111 to the vibrating feeder body 8 to ensure the stability of the inclined annular plate 111.

[0038] The inclined annular plate 111 has evenly distributed feeding notches 115, which correspond to the adjustment part 12. A U-shaped plate 116 is fixedly connected to the feeding notch 115, and a fixing hole 117 is provided on the U-shaped plate 116.

[0039] The feeding notch 115, in conjunction with the fixing hole 117 and the adjustment part 12, allows fasteners that meet the requirements to fall from the corresponding notch, thus achieving classified feeding. This facilitates the adjustment of the size of the feeding notch 115 to meet the screening needs of fasteners of different specifications.

[0040] The adjustment part 12 includes a T-shaped plate 121 and a fixing member 123. The T-shaped plate 121 is located on the U-shaped plate 116. An adjustment groove 122 is provided on the T-shaped plate 121. The fixing member 123 passes through the adjustment groove 122 and the fixing hole 117.

[0041] T-shaped plate 121 is located on U-shaped plate 116. Adjustment groove 122 cooperates with fixing member 123. By moving the position of T-shaped plate 121, the size of the space available for fasteners to fall at the material notch 115 can be changed. Fixing member 123 passes through adjustment groove 122 and fixing hole 117 to fix T-shaped plate 121, so that the equipment can sequentially screen fasteners of various specifications.

[0042] The working principle of the fastener screening device provided by this utility model is as follows:

[0043] Fasteners first enter the screening box 4 of the first screening section 1. After being vibrated and screened by the preliminary screening section 5, smaller fasteners such as nuts fall into the collection box 6, while larger fasteners such as bolts enter the second screening section 2 through the discharge channel 7. In the second screening section 2, the vibrating feeder body 8 causes the fasteners to rise in an orderly manner along the spiral feeding channel 9. They are then guided to the classification and unloading section 11 by the auxiliary structure 10. Under the action of gravity and related structures, the fasteners slide along the inclined plane. The size of the unloading notch 115 is adjusted by the adjustment section 12 to achieve sequential screening and classification of fasteners of various specifications.

[0044] Compared with related technologies, the fastener screening device provided by this utility model has the following beneficial effects:

[0045] Through the graded screening by the first screening section 1 and the second screening section 2, small fasteners such as nuts are initially filtered by the preliminary screening section 5, and then fasteners of various specifications such as bolts are screened and classified by the classification and feeding section 11 and the adjustment section 12. This improves the screening efficiency and accuracy, avoids incomplete screening, and allows the fasteners to be screened and collected in sequence, increasing the practicality of the device.
