Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel ball processing technology, and more specifically, to a precision steel ball screening and counting device. Background Technology
[0002] A precision steel ball screening and counting device is a piece of equipment used in automated production processes to screen and count steel balls. This device is used in many industries, such as machinery manufacturing, automotive industry, and precision parts processing. The steel balls to be screened are fed into the screening device via a conveyor belt or hopper. The device contains multiple screens or sieve holes. The appropriate steel balls are selected based on the size of the screens to achieve a grading effect. Typically, the lining structure and screen design can be adjusted according to the required screening specifications. During the screening process, a visual counting sensor detects the number of steel balls passing through in real time and automatically records the count. After screening and counting, qualified steel balls are automatically transported to a designated receiving device, such as a storage bin or packaging box. Because some impurities may be airborne during the steel ball screening and counting process, it is necessary to perform a dust-blocking operation on the screening and counting device.
[0003] In related technologies, during the use of screening and counting devices, impurities adhering to the surface of the visual counting sensor are generally cleaned and wiped regularly to ensure the counting effect of the visual counting sensor and thus enable its use.
[0004] However, during the current use of screening and counting devices, when cleaning the visual counting sensor by direct wiping, impurities directly rub against the visual counting sensor, causing wear and scratches, and even damaging the detection end of the visual counting sensor, thus affecting the counting and dust-proofing effect and service life of the screening and counting device.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-4 This utility model provides a technical solution: a precision steel ball screening and counting device, including a screening and counting machine 1 and a counting and dust-blocking mechanism.

A controller 4 is installed on the front side of the screening and counting machine 1, which can perform counting and dust-blocking work on the visual counting sensor 3. This prevents external impurities from directly adhering to the surface of the visual counting sensor 3, which would cause wear and damage to the detection end of the visual counting sensor 3 during subsequent impurity cleaning, thus affecting the counting accuracy and service life of the visual counting sensor 3. Therefore, the counting and dust-blocking effect and service life of the visual counting sensor 3 are improved.
[0031] Reference Figures 1-4 In a preferred embodiment, the counting dust-blocking mechanism includes a dust-blocking box 5, which is movably connected to the top of the inside of the discharge hopper 2.

The top of the lifting frame 8 is fixedly connected to the bottom of the dust-blocking pad 6. A lifting connection mechanism is provided on the front and rear sides of the inner wall of the lifting groove 7. The movable dust-blocking box 5 is fitted onto the outside of the detection end of the visual counting sensor 3, and the lifting frame 8 cooperates with the dust-blocking pad 6 to close the dust-blocking between the dust-blocking box 5 and the discharge hopper 2, causing the dust-blocking box 5 to close the visual counting sensor 3. The counting and detection end is surrounded and dustproofed. The lifting connection mechanism includes a connection port 9, a screw groove 10, and a bolt 11. The connection port 9 is opened on the front and rear sides of the inner wall of the lifting groove 7. The screw groove 10 is opened on the front and rear sides of the lifting frame 8. The bolt 11 is threaded into the inside of the screw groove 10. The bolt 11 passes through the dustproof box 5 through the connection port 9, which can perform lifting connection and prevent separation between the lifting frame 8 and the lifting groove 7. It also provides a medium for users to fix the lifting frame 8 and the dustproof box 5, avoiding the lifting frame 8 from falling out of the lifting groove 7 or being difficult to fix during use. Therefore, it improves the stability and positioning convenience of the lifting frame 8.
[0032] Reference Figures 2-4In a preferred embodiment, push grooves 12 are provided at the four corners of the bottom of the lifting frame 8. Springs 13 are provided inside the push grooves 12. One end of the springs 13 is connected to the inner wall of the push grooves 12, and the other end of the springs 13 is connected to the inner wall of the lifting grooves 7. This can apply an upward pushing force to the lifting frame 8, causing the lifting frame 8 to drive the dustproof pad 6 to contact and close with the discharge hopper 2, thus avoiding the lifting frame 8 being difficult to rise during use. Therefore, the lifting effect of the lifting frame 8 is improved. The top and bottom of the left side of the dustproof box 5 are movably connected to the force plate 14, and the bottom of the force plate 14 is movably connected to the force rod 15, which can provide the user with a medium for clamping and applying force between the dustproof box 5 and the discharge hopper 2. Therefore, the convenience of clamping and applying force between the dustproof box 5 and the discharge hopper 2 is improved.
[0033] Reference Figures 2-3 In a preferred embodiment, support frames 16 are fixedly connected to both sides of the left side of the dust box 5. A support plate 17 is movably connected to the left side of the support frame 16 via a pivot pin. The outer side of the force-applying rod 15 is located inside the support frame 16. The force-applying rod 15 can be used to connect the force-applying rod 15 and the dust box 5, thus improving the connection effect between the force-applying plate 14 and the dust box 5. A screw hole 18 is provided at the top of the force-applying rod 15. A stud 19 that penetrates the force-applying plate 14 is threaded into the screw hole 18.

The screw seat 20 is located at the top of the force-applying rod 15, which provides a medium for the user to apply threaded thrust to the bottom of the force-applying plate 14, thus improving the ease of applying force to the force-applying plate 14. A following disk 21 is movably connected to the bottom of the force-applying rod 15. The top of the following disk 21 is fixedly connected to the bottom of the stud 19, which can perform anti-displacement work between the stud 19 and the screw hole 18, thus improving the connection stability between the stud 19 and the screw hole 18.
[0035] Specifically, the working process or principle of this precision steel ball screening and counting device is as follows: During use, the device passes through the dustproof box 5 into the discharge hopper 2, with the counting detection end of the visual counting sensor 3 positioned inside the dustproof box 5. At this time, the spring 13, in conjunction with the push groove 12, applies an upward thrust to the lifting frame 8, causing the lifting frame 8 to move the dustproof pad 6 upward, thus closing the dustproof connection between the dustproof box 5 and the discharge hopper 2. During this process, the bolt 11 moves through the screw groove 10, following the lifting frame 8 within the connection port 9, thus connecting the lifting frame 8 and the lifting groove 7 to prevent separation. Subsequently, the hand-held force-applying rod 15, through the screw hole 18 and in conjunction with the stud 19, moves the force-applying plate 14 towards the discharge hopper 2, positioning the force-applying plate 14 outside the discharge hopper 2. At this time, the force-applying rod 15 moves within the support frame 16, thus moving the force-applying rod 15 and the dustproof box 5. Connect the support, then hold the stud 19 and rotate it to engage the screw hole 18 to move the force plate 14 located at the top of the discharge hopper 2 to the top of the discharge hopper 2. Rotate the screw seat 20 to engage the stud 19, and move the force plate 14 located at the bottom of the discharge hopper 2 upward, so that the force plate 14 is clamped on the outside of the discharge hopper 2, and clamp the dust box 5 to the discharge hopper 2. Then, rotate the bolt 11 to engage the screw groove 10 to fix the lifting frame 8 and the dust box 5, so that the lifting frame 8, together with the dust pad 6 and the dust box 5, performs the counting and dust prevention work for the visual counting sensor 3. Since the dust box 5 and the lifting frame 8 are both made of transparent acrylic material, the visual counting sensor 3 can work normally while blocking dust. Afterwards, the dust box 5 can be wiped regularly to clean the impurities blocked by the dust box 5 and reduce the wear and tear of the visual counting sensor 3.
[0036] It should be noted that the screening counting machine 1, the discharge hopper 2, the visual counting sensor 3 and the controller 4 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
