[0002] An electromagnet is a device that produces mechanical action through electromagnetic effect. Its typical structure is mainly composed of components such as coil, iron core, armature and shell. In practical applications, the design of electromagnet can be very diverse to adapt to different industrial needs and working environments.

[0003] In the prior art, when the electromagnet is used, the core and the armature are magnetized into two magnets with opposite polarities after the coil is energized, and the electromagnetic suction can achieve the mechanical effect of attracting the magnetic material. However, in the application of traditional electromagnets, once the electromagnet is designed, its suction force is often fixed or can only be adjusted within a limited range. This design limits the applicability of electromagnets in variable application environments. In some situations where precise control of the suction force is required (such as medical equipment operating delicate parts or food machinery handling fragile items), the fixed suction force may lead to improper operation or even damage the target object.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 An adjustable suction electromagnet includes a magnet housing 1, a mounting base 2 is fixedly connected to the magnet housing 1, and a magnetic isolation plate 3 is plugged into the mounting base 2; the insertion or removal of the magnetic isolation plate 3 can change the distribution of magnetic lines of force, thereby adjusting the suction force of the electromagnet. The design of the magnetic isolation plate 3 allows the user to accurately adjust the adsorption capacity of the electromagnet by changing the number of magnetic isolation plates 3 according to actual application requirements; the material of the magnetic isolation plate 3 includes but is not limited to soft iron and silicon steel sheets.

[0022] The magnet housing 1 is provided with a limiting structure for limiting and fixing the magnetic isolation plate 3, and the mounting seats 2 are provided with a connecting structure for connecting the mounting seats 2 in pairs.

[0023] The limiting structure includes a pair of U-shaped plates 4 fixedly connected to the top of the magnet housing 1, a connecting plate 5 fixedly connected to the opposite side walls of the two U-shaped plates 4, a limiting plate 6 slidably connected to the U-shaped plate 4, a plurality of screw grooves 7 equidistantly provided on the limiting plate 6, a bolt 8 threadedly connected to the connecting plate 5, and the bolt 8 and the screw groove 7 are threadedly connected. The arrangement of the bolt 8 and the screw groove 7 facilitates the user to move the limiting plate 6 accordingly according to the actual number of magnetic isolation plates 3, so as to ensure the limiting fixation of the magnetic isolation plates 3.

[0024] The concave side surface of the U-shaped plate 4 is close to the magnet housing 1 , the limiting plate 6 slides on the concave side surface of the U-shaped plate 4 , and the limiting plate 6 and the magnet housing 1 are in contact with each other.

[0025] The connection structure includes a connection ear 9 fixedly connected to the vertical side wall of the mounting seat 2, a bolt 10 is threadedly connected to the connection ear 9, a convex strip 11 is fixedly connected to the mounting seat 2, and a dovetail groove 12 corresponding to the convex strip 11 is provided on a side wall of the mounting seat 2 away from the convex strip 11. The arrangement of the connection ear 9 and the bolt 10 facilitates the fixation of the mounting seat 2 and the increase or decrease of the number; the arrangement of the convex strip 11 and the dovetail groove 12 enables a tighter and more precise plug-in between the mounting seats 2.

[0026] The connecting ears 9 and the convex strips 11 are arranged in pairs, thereby ensuring the stability of the connection of the mounting seat 2.

[0027] The mounting seat 2 is provided with a slot 13 for plugging in the magnetic isolation plate 3. The slot 13 is adapted to the magnetic isolation plate 3 to prevent the magnetic isolation plate 3 from shaking and affecting the adjustment of the suction force.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] When using the device, the user vertically inserts the convex strip 11 on the mounting seat 2 into the dovetail groove 12 on the mounting seat 2 that has been relatively fixed on the magnet housing 1 according to the actual suction force requirements, and then screws the bolt 10 in the connecting ear 9 to achieve relative fixation of the two mounting seats 2;

[0030] According to actual needs, the magnetic isolation plate 3 is inserted into the slot 13 to adjust the suction force of the electromagnet. At the same time, the magnetic isolation plate 3 can be inserted into different slots 13 according to actual needs. The different positions of the magnetic isolation plate 3 from the magnet also affect the suction force of the electromagnet.

[0031] After the magnetic isolation plate 3 is inserted, the user moves the limit plate 6 horizontally according to the position of the magnetic isolation plate 3, so that the limit plate 6 is located above the magnetic isolation plate 3, thereby fixing the position of the magnetic isolation plate 3 and preventing it from slipping out of the slot 13; then screw the bolt 8 on the connecting plate 5 so that the bolt 8 and the screw groove 7 are threadedly connected, thereby fixing the limit plate 6.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
