Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal separation detection, and in particular to a metal separation detector. BACKGROUND

[0002] The working principle of the metal separation detector is mainly based on electromagnetic induction or radio frequency induction. When metal impurities pass through the metal separation detector, they will interfere with the induction field, thereby generating current or signal changes. By detecting these changes, the metal separation detector can accurately identify metal impurities and trigger an alarm to prevent metal impurities from entering the product.

[0003] The conventional metal separation detector cannot perform limit correction when conveying the sample to be detected, resulting in that the sample will deviate when being conveyed on the belt conveyor and cannot pass directly below the metal detector. Moreover, the height of the conventional metal detector is fixed and inconvenient to adjust, and the practicability is low. Therefore, there are certain disadvantages.

[0004] Therefore, the application provides a metal separation detector to solve the above problems. CONTENT OF THE INVENTION

[0007] Preferably, a servo motor is installed at one end of the outer side of the fixed frame, the output shaft of the servo motor penetrates the fixed frame and is connected with one end of the bidirectional threaded rod, the outer ring surface of the bidirectional threaded rod is threadedly connected with the inner side of one end of the bottom of the movable frame, and the outer side of one end of the bottom of the movable frame is slidably connected with the inner side wall of the sliding groove.

[0008] Preferably, the limiting plate and the limiting roller outside the limiting plate are located above the belt conveyor, and the limiting plate does not interfere with the belt conveyor when moving.

[0009] Preferably, the two ends of the movable plate are in sliding connection with the two limiting columns, and the top of the limiting column is provided with a protruding block to prevent the movable plate from being separated from the two limiting columns.

[0010] Preferably, the bottom of the movable plate is provided with a fixed plate on the two sides of one end, the fixed plate is provided with an adjusting bolt, one end of the adjusting bolt is in rotating connection with a limiting arc plate, the top of the limiting arc plate is in sliding connection with the bottom of the movable plate, and the outer ring surface of the adjusting bolt is in threaded connection with the inside of the fixed plate.

[0011] Preferably, the inner side wall of the limiting arc plate is matched with the size of the outer ring surface of the limiting column, and the inner side wall of the limiting arc plate is provided with an antiskid soft pad.

The limiting arc plate moves towards the limiting column, and the inner side wall thereof extrudes the outside of the limiting column, so as to fix the movable plate on the two limiting columns, and the height of the metal detector can be adjusted conveniently and easily.

[0022] Referring to Figure 1 - Figure 3 , a servo motor 12 is arranged at one end of the outside of the fixed frame 3, the output shaft of the servo motor 12 is connected with one end of the two-way threaded rod 4 after penetrating through the fixed frame 3, the outer ring surface of the two-way threaded rod 4 is threadedly connected with the inside of one end of the bottom of the two movable frames 5, and the outer side surface of one end of the bottom of the movable frame 5 is slidingly connected with the inner side wall of the sliding groove 301, when the servo motor 12 is started, it will drive the two-way threaded rod 4 to rotate, so that the two movable frames 5 move relatively or oppositely, the sliding connection between one end of the bottom of the movable frame 5 and the inner side wall of the sliding groove 301 ensures that the movable frame 5 remains stable when moving, so as to adjust the position of the limiting roller 8 according to the width and shape of the detected sample, so as to adapt to the limiting adjustment of samples of different sizes, the limiting plate 6 and the limiting rollers 8 outside it are located above the belt conveyor 1, and the limiting plate 6 does not interfere with the belt conveyor 1 when moving, the limiting rollers 8 are installed on the limiting plate 6 through the connecting plates 7 and can roll to reduce friction with the sample, when the sample moves on the belt conveyor 1, the limiting rollers 8 will gently touch and guide the object, ensuring that the object moves along the correct path and is detected by the metal detector 11.

[0023] Referring to Figure 4The two ends of the movable plate 10 are slidably connected to the two limiting posts 9, allowing the movable plate 10 to be adjusted up and down as needed, which is convenient for testing samples of different heights.
