Description

Technical Field

[0001] This utility model relates to the field of vibration motor technology, and in particular to a core vibration motor with dustproof function. Background Technology

[0002] A vibratory motor is a device that converts electrical energy into mechanical energy. It generates excitation force by using centrifugal force produced by the high-speed rotation of the shaft and eccentric blocks, through adjustable eccentric blocks installed at both ends of the rotor shaft. The excitation force of a vibratory motor is infinitely adjustable, making it easy to use. It can be widely used in industries such as mining, metallurgy, coal, power, building materials, chemicals, casting, light industry, food, pharmaceuticals, grain, cement, ports, railways, dust removal, coating, and PCB electroplating, serving as a vibration source for various vibratory screens, vibratory feeders, vibratory finishing machines, compaction tables, and silo arch breaking and anti-blocking devices.

[0003] A vibratory motor is a device that converts electrical energy into mechanical energy. Its working principle is based on the laws of electromagnetic induction and electromagnetic force. When energized, a magnetic field is generated in the coil, which exerts a magnetic force on the iron core, causing it to vibrate. By adjusting the magnitude and direction of the current in the coil, the strength and direction of the magnetic field can be controlled, thereby controlling the amplitude and direction of the iron core's vibration.

[0004] Motors generate heat during operation and require a suitable heat dissipation structure. However, traditional partial vibration motors cannot simultaneously address dust prevention and motor protection during the heat dissipation process. Therefore, a dust-proof iron core vibration motor is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a dustproof iron core vibratory motor, comprising a lower cover 1 and an upper cover 2. A vibratory motor 3 is fixedly connected inside the lower cover 1, and a mounting plate is fixedly connected to the bottom of the lower cover 1. A heat dissipation mechanism is fixedly connected to the top of the upper cover 2, and a disassembly and assembly mechanism is slidably connected inside the lower cover 1. The lower cover 1 is the lower protective structure of the entire iron core vibratory motor, with the vibratory motor 3 fixedly connected inside. The mounting plate at its bottom is used for the overall installation and fixation of the motor. The lower cover 1 and the upper cover 2 cooperate to form a relatively enclosed space, protecting the internal vibratory motor 3 from external dust and moisture. The vibratory motor 3 is the core component of the entire device. Its vibration acts on the iron core and other components, producing the required vibration effect. Its normal operation directly affects the functionality of the entire device. During operation, it generates heat, requiring a heat dissipation mechanism to regulate the working environment temperature, and also requires the protection of the lower cover 1 and the upper cover 2 to prevent external factors from affecting it.

[0034] The heat dissipation mechanism includes an air inlet pipe 4, which is fixedly connected to the top of the upper cover 2. A connecting pipe 5 is fixedly connected to the bottom of the air inlet pipe 4. Air inlet covers 6 are fixedly connected to both sides of the connecting pipe 5. The connecting pipe 5 serves as an intermediate connection for air transmission, distributing the air introduced by the air inlet covers 6 into the air inlet pipe 4. The arrangement of two air inlet covers 6 increases the air intake area, which helps to improve the efficiency of air intake and allows more air to enter the entire heat dissipation system, thereby better dissipating heat from the vibration motor 3 and purifying the air. A square box 7 is fixedly connected to the front end of the air intake pipe 4. The bottom end of the square box 7 is fixedly connected to the top end of the upper cover 2. The square box 7 is the main place for air purification. A disassembly frame 8 is detachably connected to the top of the square box 7. A filter plate 13 is fixedly connected to the rear side of the bottom end of the disassembly frame 8. The filter plate 13 adsorbs dust in the air passing through the square box 7 to prevent dust from entering the working environment of the vibration motor 3 and avoids dust damage to the motor. A moisture-absorbing plate 14 is fixedly connected to the front side of the bottom end of the disassembly frame 8. The moisture-absorbing plate 14 absorbs moisture in the air passing through the square box 7 to reduce the moisture in the air and prevent moisture from causing corrosion to the vibration motor 3 or affecting its electrical performance, thus creating a dry working environment for the motor.

[0035] A fan 9 is fixedly connected to the front end of the square box 7. The bottom end of the fan 9 is fixedly connected to the top end of the upper cover 2. An air outlet pipe 10 is fixedly connected to the output end of the fan 9. The fan 9 generates power to drive the air flow in the lower cover 1 and the upper cover 2, so that the air enters the square box 7 through the air inlet hood 6 and other structures for purification. Then, the purified and dried air is output through the air outlet pipe 10, which is the power source for the entire air circulation. A connecting pipe 2 11 is fixedly connected to the output end of the air outlet pipe 10. Air outlet hoods 12 are fixedly connected to both sides of the connecting pipe 2 11. The air outlet pipe 10 delivers the air driven and purified by the fan 9 to the connecting pipe 2 11. The connecting pipe 2 11 distributes the air from the air outlet pipe 10 to the air outlet hoods 12, so that the air is blown evenly to the vibration motor 3, improving the heat dissipation effect, cooling the vibration motor 3, and ensuring that the motor operates at a suitable temperature to avoid overheating and failure.

[0036] Reference Figure 1 , Figure 2 and Figure 4The disassembly and assembly mechanism includes multiple square plates 16. A cavity 15 is formed at each of the four corners of the lower cover 1. The outer walls of the square plates 16 are slidably connected to the inner walls of the cavity 15. Two connecting rods 17 are fixedly connected inside the square plates 16. Springs 18 are sleeved on the outside of the connecting rods 17. The opposite sides of the multiple springs 18 are fixedly connected to the adjacent sides of the two square plates 16. The adjacent sides of the multiple springs 18 are fixedly connected to the adjacent inner walls of the two cavity 15. Two locking blocks 19 are fixedly connected to the opposite sides of the multiple connecting rods 17. The outer walls of the locking blocks 19 are slidably connected to the inner walls of the cavity 15. Insert blocks 22 are fixedly connected at each of the four corners of the bottom of the upper cover 2. The bottoms of the multiple insert blocks 22 are slidably connected to the inside of the lower cover 1. The bottoms of the insert blocks 22 engage with the outside of the locking blocks 19. The cavity 15 provides space for the square plates 16, connecting rods 17, springs 18, and locking blocks 19, ensuring that these structures can move normally during installation and disassembly. It is an important component of the disassembly and assembly mechanism. When installing the upper cover 2, the square plate 16 will compress the spring 18 along with the connecting rod 17 when the insert block 22 presses against the locking block 19. As the locking block 19 moves, the connecting rod 17 transmits force to the square plate 16, and simultaneously, under the action of the spring 18, the locking block 19 is reset, thus playing a role in force transmission and connection. The spring 18 provides elasticity and reset. The bottom of the insert block 22 has a slot that engages with the locking block 19 after installation. A sealing ring 23 is fixedly connected to the top of the lower cover 1, with the top side of the sealing ring 23 contacting the bottom side of the upper cover 2. When installing the upper cover 2 and the lower cover 1, the sealing ring 23 provides a seal, preventing external dust and moisture from entering the interior through the connection point, thus protecting the working environment of the vibration motor 3. Multiple locking blocks 19 are fixedly connected to transmission rods 20 on opposite sides. The external sides of the multiple transmission rods 20 are slidably connected to the inside of the lower cover 1. Control plates 21 are fixedly connected to opposite sides of the multiple transmission rods 20. The adjacent sides of the multiple control plates 21 are in contact with the outer side of the lower cover 1. When disassembling the upper cover 2, by moving the control plates 21, the transmission rods 20 transmit force to the locking blocks 19, causing the locking blocks 19 to move and release from the engagement with the insert block 22, thus playing the role of force transmission.

[0037] Working principle: By turning on the fan 9, the air inside the lower cover 1 and the upper cover 2 is driven to flow. The air enters the square box 7 through the air inlet hood 6, connecting pipe 1 5 and air inlet pipe 4. The filter plate 13 adsorbs dust and impurities in the air, and then the moisture absorption plate 14 absorbs moisture in the air. The clean and dry air is delivered to the air outlet pipe 10 by the fan 9, and finally blown onto the vibrating motor 3 through the connecting pipe 2 11 and air outlet hood 12. This removes dust and moisture from the air inside the lower cover 1 and the upper cover 2, and cools and protects the vibrating motor 3.

[0038] When the upper cover 2 needs to be installed on the lower cover 1, the upper cover 2 is aligned with the lower cover 1 and pressed down, which in turn drives the insert block 22 to move downward. The downward movement of the insert block 22 compresses the locking block 19, causing it to move inward into the chamber 15. This movement of the chamber 15 drives the connecting rod 17 and the square plate 16 to move inward, compressing the spring 18. When the upper cover 2 and the sealing ring 23 on the lower cover 1 are tightly fitted together, and the insert block 22 is fully inserted into the lower cover 1, the pressure generated by the compression of the spring 18 drives the square plate 16, the connecting rod 17, and the locking block 19 to move outward. This allows the locking block 19 to move outward and engage with the bottom of the insert block 22, thus achieving the installation of the lower cover 1 and the upper cover 2. When the vibration motor 3 needs to be repaired, the locking block 19 is moved by moving the control plate 21 in conjunction with the transmission rod 20 to release the engagement with the insert block 22, allowing the upper cover 2 to be removed from the lower cover 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
