Description

Technical Field

[0001] The utility model belongs to the technical field of vibration mill manufacturing, in particular to a fine vibration mill for magnetic core raw materials. Background Art

[0002] Vibration mill, also known as vibration mill, is an ultra-fine grinding equipment with balls or rods as the medium. The main working principle is to generate energy through the driving motor, which then drives the medium to vibrate inside the mill, so that materials smaller than 2mm are crushed to several microns. This equipment is widely used in medicine, feed veterinary medicine, food, daily chemicals and other industries, such as micro-processing of Chinese medicinal materials, trace element additives, grain powder, facial mask powder, etc.

[0003] Common vibration mills have certain limitations in vibration range, which affects their fineness and vibration efficiency, making it difficult to achieve the ideal fine grinding effect. Due to the small vibration range, the movement trajectory of the material in the mill is restricted, so that the contact area and collision frequency between the material and the medium are limited. In terms of fineness, the insufficient vibration range makes it impossible to fully grind the material to a smaller particle size; in terms of vibration efficiency, the limitation of the vibration range limits the mill's ability to process materials per unit time. Due to the insufficient collision between the material and the medium, it takes a longer time to achieve the expected grinding effect. Utility Model Content

[0004] The utility model aims to provide a fine vibration grinding device for magnetic core raw materials in order to solve the problems of small vibration range, poor fineness and vibration grinding efficiency of common vibration grinding machines.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: it comprises a bottom plate, a plurality of mounting brackets are arranged above the bottom plate, a vibration mill cylinder is arranged on the inner side of the mounting bracket, a motor is arranged on the side of the vibration mill cylinder, the vibration mill cylinder comprises an outer cylinder and an inner cylinder, a feed port is arranged on the top of the inner cylinder, the feed port passes through the outer cylinder, a center tube is arranged on the inner side of the inner cylinder, circular plates are arranged at both ends of the outer cylinder and are connected by screws, the circular plates and the inner cylinder are tightly attached to each other to form a seal, a plurality of first springs are equidistantly arranged between the inner cylinder and the outer cylinder, and the two ends of the first spring are connected to the inner cylinder and the outer cylinder by screws.

[0006] Furthermore, the mounting bracket is penetrated by the vibration cylinder and connected by screws, and a plurality of second springs are provided between the bottom of the mounting bracket and the base plate and connected by screws.

[0007] Furthermore, an eccentric shaft and an eccentric weight installed on the eccentric shaft are provided in the central tube, and the eccentric shaft is connected to the central tube via a rotating shaft.

[0008] Furthermore, a discharge port is fixedly provided on one side of the vibration grinding cylinder, and the discharge port is connected with the inner cylinder through-through.

[0009] Furthermore, a support block is provided at the bottom of the motor, the support block is connected to the base plate and the motor via screws, and the motor is connected to the eccentric shaft via a flexible coupling.

[0010] Beneficial effects: The utility model has reasonable design and has the following beneficial effects:

[0011] 1. In the scheme of the utility model, an inner cylinder capable of irregular shaking is arranged in the vibration grinding cylinder, thereby increasing the vibration range and the vibration amplitude of the medium in the cylinder body, thereby increasing the number of medium throwing and mutual impact, so that the material sandwiched between the media is subjected to more impact and grinding, thereby improving the efficiency and fineness of vibration grinding;

[0012] 2. In the solution of the utility model, since the two ends of the inner cylinder are restricted by the circular plates and cannot move, it can only swing to the side of the cylinder body, which reduces the lateral swing direction of the inner cylinder to prevent the material from falling into the space between the inner cylinder and the outer cylinder. The first spring assists the swing while preventing the inner cylinder and the outer cylinder from directly colliding, and provides a pulling effect on the inner cylinder to prevent the inner cylinder from getting out of control, thereby enhancing the stability of the equipment.

[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] Combination Figures 1 to 4 A magnetic core raw material fine vibration grinding device shown in the figure includes a bottom plate 1, a plurality of mounting brackets 2 are arranged above the bottom plate 1, a vibration grinding cylinder 3 is arranged inside the mounting bracket 2, a motor 4 is arranged on the side of the vibration grinding cylinder 3, the vibration grinding cylinder 3 includes an outer cylinder 31 and an inner cylinder 32, a feed port 33 is arranged on the top of the inner cylinder 32, the feed port 33 passes through the outer cylinder 31, a center tube 34 is arranged inside the inner cylinder 32, circular plates 35 are arranged at both ends of the outer cylinder 31 and are connected by screws, the circular plates 35 and the inner cylinder 32 are tightly attached to each other to form a seal, and a plurality of first springs 37 are equidistantly arranged between the inner cylinder 32 and the outer cylinder 31, and the first springs 37 are arranged at equal distances. Both ends of 37 are connected to the inner cylinder 32 and the outer cylinder 31 by screws, and the circular plate 35 is penetrated by the central tube 34. When the vibration cylinder 3 vibrates, the inner cylinder 32 shakes irregularly under the action of inertia. The first spring 37 assists the shaking while preventing the inner cylinder 32 from directly colliding with the outer cylinder 31, so as to facilitate the irregular shaking of the inner cylinder 32 and provide a pulling effect to prevent the inner cylinder 32 from getting out of control. The two ends of the inner cylinder 32 are restricted by the circular plate 35 and cannot move forward and can only shake to the side of the cylinder body. The feed port 33 is connected to the outer cylinder 31 but not to the inner cylinder 32. When the equipment is running, the top of the inner cylinder 32 is closed to prevent material from splashing.

[0022] The mounting bracket 2 is penetrated by the vibration mill cylinder 3 and connected by screws. A plurality of second springs 21 are provided between the bottom of the mounting bracket 2 and the bottom plate 1 and connected by screws, so that the mounting bracket 2 and the vibration mill cylinder 3 can vibrate simultaneously and maintain the connection stability.

[0023] An eccentric shaft 341 and an eccentric weight 342 mounted on the eccentric shaft 341 are arranged in the center tube 34. The eccentric shaft 341 and the center tube 34 are connected via a rotating shaft. When the eccentric shaft 341 and the eccentric weight 342 rotate, the body of the vibration grinding cylinder 3 supported on the second spring 21 vibrates due to the inertial centrifugal force.

[0024] A discharge port 5 is fixedly provided on one side of the vibration mill cylinder 3, and the discharge port 5 is connected to the inner cylinder 32 through the hole of the discharge port 5 within the vibration range of the inner cylinder 32 to prevent the material from falling between the inner cylinder 32 and the outer cylinder 31;

[0025] A support block 6 is provided at the bottom of the motor 4. The support block 6 is connected to the bottom plate 1 and the motor 4 through screws. The motor 4 is connected to the eccentric shaft 341 through a flexible coupling.

[0026] Working principle: When the utility model is in use, after the raw materials are fed into the inner cylinder filled with grinding media through the feed port, the motor drives the eccentric shaft and the eccentric weight to rotate through the elastic coupling. Due to the action of inertial centrifugal force, the vibration grinding cylinder supported on the second spring vibrates, and the inner cylinder is also affected by inertia and vibrates. Since the two ends of the inner cylinder are restricted by circular plates and cannot move, it can only shake to the side of the cylinder body. The first spring assists the shaking while avoiding direct collision between the inner cylinder and the outer cylinder, and provides a pulling effect on the inner cylinder to avoid the inner cylinder from getting out of control. When the vibration frequency increases, the medium in the cylinder body vibrates with the inner cylinder, causing the medium to rotate, throw and impact each other, and the material sandwiched between the media is crushed by the impact and grinding.
