Furthermore, existing dustproof sealing structures cannot easily adjust the dustproof area, making it impossible to precisely control the dustproof range according to actual needs, significantly reducing the dustproof sealing effect and failing to adequately meet the diverse dustproof sealing requirements of actual production. Therefore, those skilled in the art have provided a dustproof sealing structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The objective of this utility model is achieved through the following means: A dustproof sealing structure includes a feeder base with side plates rotatably hinged to both sides. A sliding groove is formed on the side plate, and a screw is installed within the groove. A main plate is connected to the screw. A secondary plate is positioned above the main plate. A positioning hole is formed on the upper side of the main plate, and slots are formed on both sides of the positioning hole. A retaining strip is installed on the bottom side of the secondary plate, and a bracket is installed on the upper side of the secondary plate. A limit rod is vertically sleeved inside the bracket, and a spring is sleeved on the limit rod.

[0006] Furthermore, the end of the main board facing the side plate is slidably inserted into the slide groove, and the end of the main board facing the slide groove is threadedly connected to the screw. By rotating the screw, the main board and the sub-board can be raised and lowered, thereby adjusting the height of the protective cover formed by the main board and the sub-board.

[0007] Furthermore, the motherboard is provided in two parts, and magnetic plates are installed on the sides of the two motherboards, and the two magnetic plates are magnetically connected.

[0008] Furthermore, the sub-board is slidably engaged with the slot on the main board via a locking strip.

[0009] Furthermore, the bracket is L-shaped.

[0010] Furthermore, a convex ring is installed on the limiting rod, the bottom end of the spring is in abutting contact with the convex ring, the top end of the spring is in abutting contact with the upper end of the bracket, and the lower end of the limiting rod passes through the sub-plate and is inserted into the positioning hole for positioning, thereby positioning the sub-plate. Therefore, the distance between the two sub-plates can be adjusted to achieve the effect of adjusting the dustproof area.

[0011] The beneficial effects of this utility model are as follows: Side plates are provided on both sides of the feeder base, and screws are installed in the inner grooves of the side plates. A main plate and a sub-plate are threaded onto the screws. By rotating the screws to drive the main plate and sub-plate to rise and fall, the height of the protective cover formed by the main plate and sub-plate can be flexibly adjusted. This allows the dustproof sealing structure to be adapted to feeding components of different heights. A positioning hole and a groove are opened on the upper side of the main plate. The sub-plate is slidably engaged with the groove by a locking strip. Using a limiting rod vertically inserted into the L-shaped bracket on the upper side of the sub-plate, combined with the convex ring and spring on the periphery of the limiting rod, the positioning bolt is inserted through the positioning hole of the sub-plate and the main plate under the pressure of the spring. This allows for flexible adjustment of the distance between the two sub-plates, realizing effective adjustment of the dustproof area of ​​the main plate and sub-plate, improving the adaptability of the dustproof sealing structure to feeding components of different sizes, and better exerting the dustproof sealing function.
