[0039] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0040] Combination Figure 1 and Figure 2 A vibrating plate for conveying buttons, comprising: a vibrator 1 for driving a material plate 2 to vibrate, the material plate 2 being mounted on the upper end of the vibrator 1, and having a spiral upward feeding channel 21 in the material plate 2; a screening device being mounted in the feeding channel 21, and forming a screening area 1 91 and a screening area 2 92 for screening materials in the feeding channel 21; the screening device comprising: a screening plate 3, which is movably arranged on the material plate 2, and the front end of which is placed in the feeding channel 21, and the front end of the screening plate 3 is provided with The screening part 1 31 and the screening part 2 32 are both provided with screening teeth 30; a material guide plate 1 4, which is movably arranged on the side wall of the feeding channel 21, and cooperates with the screening part 1 31 to form a screening area 1 91; a material guide plate 2 5, which is movably arranged on the side wall of the feeding channel 21, and cooperates with the screening part 2 32 to form a screening area 2 92; and an adjusting mechanism 6, which is movably connected to the side wall of the feeding channel 21, and is used to adjust the curvature of the material guide plate and thus adjust the size of the screening area.

[0041] like Figure 4 The tooth pitch of the screening teeth 30 of the screening part 1 31 is different from the tooth pitch of the screening teeth 30 of the screening part 2 32. The tooth pitch of the screening teeth 30 of the screening part 1 31 is greater than the tooth pitch of the screening teeth 30 of the screening part 2 32. The outer diameter of the buttons screened in the screening area 1 91 is greater than the outer diameter of the buttons screened in the screening area 2 92.

[0042] When the outer diameter of the buttons to be screened is large, the user can select screening area 1 91 to screen the buttons. When the outer diameter of the buttons to be screened is small, the user can select screening area 2 92 to screen the buttons. The operation is simple and convenient.

[0043] Combination Figures 2 to 4The adjusting mechanism 6 comprises: an adjusting piece 61, an adjusting piece 62 and a nut; the adjusting piece 61 and the adjusting piece 62 are screws or bolts; the adjusting piece 61 is threadedly connected to the side wall of the feeding channel 21, and the front end of the adjusting piece 61 movably abuts against the side wall of the front section of the guide plate 4; the adjusting piece 62 is threadedly connected to the side wall of the feeding channel 21, and the front end of the adjusting piece 62 movably abuts against the side wall of the front section of the guide plate 25; the adjusting piece 61 and the adjusting piece 62 are both threadedly connected with nuts, and the nuts fix the positions of the adjusting piece 61 and the adjusting piece 62 on the side wall of the feeding channel 21, so that the guide plate can maintain a bent state.

[0044] By adjusting the adjusting piece 61, the front section of the guide plate 4 is bent, so that the size of the screening area 91 is adjusted to a size suitable for the passage of buttons. By adjusting the adjusting piece 62, the front section of the guide plate 5 is bent, so that the size of the screening area 92 is adjusted to a size suitable for the passage of buttons. When the outer diameters of the buttons are not much different, the screening area can be adjusted to meet the button screening needs by adjusting the adjusting piece to bend the guide plate. The operation is simple and the adaptability is good.

[0045] Combination Figure 2 and Figure 4 A waist-shaped hole 41 is provided at the rear section of the guide plate 4, and the waist-shaped hole 41 can be vertically or horizontally arranged on the guide plate 4, and the end of the connecting piece 42 (screw or bolt) passes through the waist-shaped hole 41 and is connected to the side wall of the feeding channel 21, so that the guide plate 4 is installed in the material tray 2; the guide plate 4 rotates on the side wall of the feeding channel 21 through the waist-shaped hole 41, so that the lower side of the front section of the guide plate 4 is separated from the bottom side of the feeding channel 21, so as to avoid the guide plate 4 affecting the transportation of buttons to the screening area 292 when the buttons are screened in the screening area 292, and the guide plate 4 is rotated and adjusted through the waist-shaped hole 41, and there is no need to rotate the connecting piece 42 to remove the guide plate 4, which saves trouble and effort.

[0046] The rear section of the guide plate 2 5 is similar in structure to the guide plate 1 4 , and both can be connected to the side wall of the feeding channel 21 by using a connecting piece.

[0047] Combination Figure 2 and Figure 4 A avoidance hole 51 is opened on the rear section of the guide plate 25 for the front end of the adjusting member 61 to pass through. When the adjusting member 61 is used to bend and adjust the guide plate 4, the avoidance hole 51 avoids affecting the adjusting member 61 from extending into and abutting against the side end wall of the guide plate 4, so that the bending adjustment of the guide plate 4 can be achieved without disassembling the guide plate 25, which saves trouble and effort.

[0048] Combination Figures 2 to 4The front side of the screening plate 3 has a receiving portion 34, and the inner side of the receiving portion 34 is provided with a rib 35. When the buttons are screened out from the screening area and enter the receiving portion 34, the rib 35 prevents the screened buttons from falling back into the material tray 2, thereby improving the efficiency of screening and transportation; the outer side of the receiving portion 34 is in contact with the feeding channel 21, so that the buttons can be moved from the receiving portion 34 to the feeding channel 21 again, and transported to the button sewing machine through the end of the feeding channel 21.

[0049] A receiving portion 33 is provided on the other side of the front end of the screening plate 3, and the outer side of the receiving portion 33 is in contact with the feeding channel 21 for guiding the buttons to move into the screening area.

[0050] Combination Figures 2 to 4 A mounting opening 22 is provided on the side wall of the feeding channel 21 , and the mounting opening 22 is provided with an adjustment seat 7 whose curvature matches the feeding channel 21 , and the sieve plate 3 is inserted between the bottom end of the adjustment seat 7 and the feeding channel 21 .

[0051] Combination Figures 2 to 4 A mounting portion 23 is provided on the outer side of the feeding channel 21, and the mounting portion 23 is located at the lower end of the mounting opening 22. The screening plate 3 is provided with a plurality of waist-shaped holes 36. The front end of the connecting piece 37 (screw or bolt) passes through the waist-shaped hole 36 and is threadedly connected to the mounting portion 23, so that the screening plate 3 is installed on the material tray 2.

[0052] Combination Figures 2 to 4 A material-diverting piece 8 with a tip bent toward the center of the material tray 2 is provided on the side wall of the feeding channel 21. A spacing for a button to pass through is provided between the material-diverting piece 8 and the bottom end of the feeding channel 21. The material-diverting piece 8 prevents two or more buttons from being transported overlappingly.

[0053] Combination Figures 2 to 4 A material drop hole 38 is provided on the screening plate 3, and screening teeth 30 are provided at the edge of the material drop hole 38 to form a second screening section 32. When the buttons are screened using the second screening area 92, buttons that do not meet the requirements fall back into the material tray 2 from the material drop hole 38.
