Detailed Description

Referring to fig. 1-4, the fluorescent powder grinding and screening device of the present invention comprises a base 1 and a frame 2 fixed on the base, wherein a grinding module 3 is arranged on the frame 2. Grind module 3 top and be provided with feed chute fill 4, the below is provided with screen cloth 5, screen cloth 5 is connected with vibration mechanism 6. The gate plate for controlling the switch is arranged at the discharge port of the feeding trough hopper, and the structure is the prior art and is not shown in the figure. The gate structure may take on various configurations known in the art.

The screen 5 is connected with a rotary drive mechanism 7. In this embodiment, the rotary driving mechanism 7 comprises a linkage shaft 7a connected to the frame 2 above the feeding chute 4 through a bearing, and one end of the linkage shaft 7a is connected to a servo motor 7b with a braking function; and a connecting rod 7c connected with the screen 5 is fixedly arranged on the linkage shaft 7 a. The structure of the connecting rod can be determined according to specific conditions. Provided that the screen does not come into contact with other parts during the movement.

Wherein one end is provided with arc collecting chute 8 along length direction at screen cloth 5, and when 7 drive screen cloths 5 were rotatory at rotary driving mechanism, the nonconforming material that is located on screen cloth 5 got into arc collecting chute 8 in, rotary driving mechanism 7 drove screen cloth 5 and continues to rotate, made arc collecting chute 8 rotatory to feeding chute fill 4 top and export nonconforming material in the arc collecting chute 8 to feeding chute fill 4 in.

Referring to fig. 3-4, preferably, a material guide hopper 9 matched with the arc-shaped material collecting groove 8 is arranged on one side of the opening end of the material feeding groove hopper 4 in an inclined manner and faces upwards, an included angle between the inner bottom surface of the material guide hopper 9 and the horizontal plane is 15-20 degrees, and the included angle between the inner bottom surface of the material guide hopper and the horizontal plane is not too large, so that dust is prevented from flying due to too high material sliding speed, and material waste and environmental pollution are prevented.

An extension piece 10 made of flexible materials is arranged at the lower end of a feeding hole of the material guide hopper 9, and the included angle between the extension piece 10 and the horizontal plane is 30-45 degrees.

The side wall of the arc-shaped material collecting groove 8 is conductively connected with a material outlet 11 matched with the material guide hopper 9, and a guide oblique block can be arranged in the arc-shaped material collecting groove to ensure that the material on the screen mesh is guided to enter the material outlet. The free end of the discharge port 11 is connected with a yielding groove 12 made of flexible materials.

When the abdicating groove 12 rotates to the material guiding hopper 9, the abdicating groove 12 contacts with the end of the extension piece 10 and rotates to the upper part of the extension piece 10 after elastic deformation. When the groove of stepping down begins the slope ejection of compact behind the extension piece promptly, when the material in the arc collecting chute just begins to empty, discharge gate and horizontal plane angle are less, and material moving speed is slower, and the material is difficult not only to get into the guide fill, easily perpendicular from the discharge gate output moreover, consequently need set up the extension piece of flexible material preparation and step down the groove and be used for guaranteeing that the material can empty and get into in the guide fill.

A sensor 13 is arranged on the frame above the feeding trough hopper 4, and a sensing piece 14 matched with the sensor 13 is arranged on the rotary driving mechanism 7. When the abdicating groove 12 rotates to the upper end near end part of the feeding hole of the material guiding hopper 9, the sensor 13 detects the sensing piece 14, and the rotation driving mechanism 7 brakes. After braking, the rotary driving mechanism stands for a preset time to completely output the materials into the material guide hopper.

Further preferably, a dust-proof plate 15 is arranged at the upper end of the feeding hole of the material guide hopper 9. A high-position material guide plate 16 is arranged in the material guide hopper 9 above the extension piece 10, and the included angle between the high-position material guide plate 16 and the horizontal plane is 15-30 degrees. When the abdicating groove 12 rotates past the extending piece 10 and then rotates to the position above the high-position material guide plate 16, the unqualified material output by the abdicating groove 12 enters the material guide hopper 9 through the high-position material guide plate 16 and the extending piece 10 does not contact with the high-position material guide plate 16 in the rotating process. When the groove of stepping down rotated to and is higher from the extension piece, the displacement distance that the material descends is longer, very easily produces the raise dust phenomenon, sets up high-order stock guide and can effectively shorten the distance, reduces the emergence of raise dust.

Preferably, the vibrating mechanism 6 includes baffle plates 6a provided at the proximal end portions of both ends of the bottom of the mesh 5 in the swinging direction of the mesh 5. A bracket 6b is arranged on the base 1 at the outer side of one baffle 6a, and a reset stop 6c matched with the baffle 6a is connected to the bracket 6b through a spring.

A lifting cylinder 6d is arranged on the base 1 below the other baffle, and the free end of a piston rod of the lifting cylinder 6d is connected with a motor mounting seat 6 e. The motor mounting seat 6e is fixedly provided with a motor 6f, and the free end of an output shaft of the motor 6f is connected with an eccentric wheel 6g matched with the side baffle 6 a. The screen 5 is vibrated back and forth by the eccentric 6g and the reset stopper 6 c.

The vibrating mechanism with the structure can be well matched with the screen mesh hinged on the rack, when the screen mesh needs to rotate, the lifting cylinder drives the motor to descend by a preset height, so that the eccentric wheel is positioned at the lower side of the corresponding baffle, and the screen mesh and the baffle at the bottom of the screen mesh are ensured not to be contacted with the eccentric wheel in the rotating process.

In this embodiment, the grinding module 3 includes a mounting frame 3a fixedly mounted on the frame 2, and a mounting box 3b is fixedly disposed on the mounting frame 3 a; at least two groups of grinding rollers 3c are arranged in the mounting box body 3b, each grinding roller 3c is matched and fixed on the mounting box body 3b through a shaft seat and a bearing, and a connecting long hole matched with each shaft seat is arranged on the mounting box body 3 b; a grinding motor 3d is connected to one end of each grinding roller 3 c. When the grinding equipment breaks down or the grinding roller is worn and aged, the whole mounting box body can be directly detached for maintenance and replacement. Meanwhile, according to different processing requirements, the gap between the grinding rollers can be adjusted through the connecting long holes so as to change the particle size of the powder.

In this embodiment, each motor is connected to a distribution box or a corresponding control terminal, and the corresponding connection mode and the working principle thereof are prior art and are not described herein again.

During the use, pour the material into the feeding groove fill, start and grind the module, open the flashboard, the material sieves in getting into reciprocating motion's the screen cloth after grinding, in qualified material gets into the storing basket of screen cloth bottom. When the screening of the preset amount of materials is finished or more unreasonable materials are accumulated in the screen.
