DETAILED DESCRIPTION

[0021] See also Figure 1-4 , the embodiments of the utility model are further described;

[0022] A button screening device comprises a material box 1 with an inclined bottom, a support frame 2 fixed below the material box 1, and a vibrator 7 installed between the material box 1 and the support frame 2;

[0023] A material guide hopper 4 with a cross section decreasing from top to bottom is installed in the material box 1, a plurality of longitudinally distributed material guide inclined plates 5 are fixed in the material guide hopper 4, a vibrating rod 6 in contact with the material guide hopper 4 is installed in the material box 1, and a feed pipe 3 communicating with the interior of the material box 1 is fixed on the top of the material box 1;

[0024] Specifically, Figure 1 As shown, the buttons to be screened can be poured into the material box 1 through the feed pipe 3. After entering the material box 1, the buttons will enter the guide hopper 4. Since the cross-section of the guide hopper 4 decreases from top to bottom, the discharge amount of the guide hopper 4 can be effectively controlled, and a large amount of material can be prevented from accumulating at the bottom of the material box 1 and the discharge end. The setting of multiple guide inclined plates 5 can guide the buttons in the guide hopper 4, and due to the presence of multiple guide inclined plates 5, the discharge amount of the guide hopper 4 can be further controlled. Since the amount of buttons falling on the bottom of the material box 1 is small, the pressure of the device on the button screening in the later stage can be greatly reduced, thereby improving the efficiency of button screening.

[0025] A control panel 16 is installed on the material box 1, and a mounting groove 11 is opened at the material box 1 discharge end, an electric lifting rod 12 electrically connected to the control panel 16 is fixed in the mounting groove 11, a material baffle plate 13 is fixed at the lower end of the electric lifting rod 12, and the lower end of the material baffle plate 13 is parallel to the bottom of the material box 1;

[0026] Specifically, before screening the buttons, the upward or downward movement of the electric lifting rod 12 is set through the control panel 16 according to the thickness of the buttons, that is, the vertical distance between the baffle plate 13 and the bottom of the material box 1 is adjusted. After the control panel 16 starts the electric lifting rod 12, the electric lifting rod 12 will drive the baffle plate 13 to move up or down. When the lower end of the electric lifting rod 12 is adjusted to the specified position, the control panel 16 will close the electric lifting rod 12. The setting of the electric lifting rod 12 and the baffle plate 13 can adjust the height of the discharge end of the material box 1 according to the buttons of different thicknesses, thereby realizing the screening of buttons of different thicknesses. The structure is simple, convenient for the manufacture of the device, and convenient for the staff to operate.

[0027] When screening buttons, the staff can connect the vibrator 7 to the power supply, and the vibrator 7 will vibrate the bottom of the material box 1 to promote the button screening. When the material box 1 vibrates, it will drive the guide hopper 4 and the vibrating rod 6 inside it to vibrate, and when the vibrating rod 6 vibrates, it will also drive the guide hopper 4 to vibrate, so that the material in the guide hopper 4 is gradually discharged to avoid the situation that the material inside the guide hopper 4 is blocked.

[0028] A conveyor belt 14 is provided on one side of the material box 1 and is located below the discharge end. A stand 15 is installed on one side of the conveyor belt 14. The top of the stand 15 is located above the conveyor belt 14 and is parallel to the conveyor belt 14. Two size detection components are installed on the top of the stand 15. The size detection components are electrically connected to the control panel 16.

[0029] Specifically, before the device is used, the size of the buttons that meet the standards is tested by the size detection component. After the test, the data is entered into the control panel 16 as a standard for later reference. A loading bag or loading barrel is placed at the discharge end of the conveyor belt 14 for later material collection.

[0030] The screened buttons will be directed to the conveyor belt 14, which is used to transport the buttons. During the transportation process, the size detection component will detect the buttons on the conveyor belt 14 one by one. If all the buttons are detected to be qualified, the conveyor belt 14 will operate normally; if unqualified buttons are detected, the control panel 16 will turn off the conveyor belt 14, and the staff can observe the buttons near the size detection component and pick out the unqualified buttons.

[0031] The size detection assembly includes a row of cameras 17 and a row of multi-color lights 18, and the cameras 17 and the multi-color lights 18 are electrically connected to the control panel 16;

[0032] Furthermore, before the device is used, the camera 17 is used to capture images of qualified buttons, and the data is entered into the control panel 16 as a standard for later reference. It should be noted that the multi-color light 18 can turn on white, blue, and red lights. Under normal circumstances, the white light can illuminate the conveyor belt 14, which is conducive to the camera 17 to capture the buttons on the conveyor belt 14; if the multi-color light 18 turns on the blue light, it means that a small number of unqualified buttons have been detected; if the multi-color light 18 turns on the red light, it means that a large number of unqualified buttons have been detected.

[0033] During the process of conveying buttons on the conveyor belt 14, the camera 17 will take pictures of the buttons on the conveyor belt 14, and the pictures taken will be transmitted to the control panel 16, and compared with the qualified button images in the control panel 16. If the buttons photographed are all qualified, the conveyor belt 14 works normally, and the multi-color light 18 keeps on lighting white; if a small number of defective, deformed or prickly buttons are photographed, the control panel 16 will turn off the conveyor belt 14, and the multi-color light 18 will turn on the blue light. At this time, the staff can observe the area where the blue light appears on the conveyor belt 14, and can quickly sort out the unqualified buttons; if more defective, deformed or prickly buttons are photographed, the control panel 16 will turn off the conveyor belt 14, and the multi-color light 18 will turn on the red light, indicating that there are more unqualified buttons in the red light area of ​​the conveyor belt 14. According to the above feedback, the button production situation can be timely understood to reduce losses. The setting of the size detection component can assist the staff to quickly sort out unqualified buttons.

[0034] A filter screen 8 is installed through an opening at the bottom of the material box 1 and near the discharge end;

[0035] Specifically, a small amount of dust will be attached during the button production process. When the vibrator 7 vibrates the material box 1 and the buttons move to the filter screen 8, the dust on the buttons can be discharged through the filter screen 8.

[0036] A funnel 9 covering a filter screen 8 is sealed at the bottom of the material box 1, and a dust collecting box 10 located below the funnel 9 is placed in the support frame 2;

[0037] Furthermore, dust passes through the filter 8 and falls into the funnel 9, and the dust is guided into the dust box 10 through the funnel 9 to be collected.
