Description

Technical Field

[0001] The utility model relates to the field of silicon nitride ceramic ball production, in particular to a cleaning device for silicon nitride ceramic ball production. Background Art

[0002] Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. They can be used in highly polluted environments without lubricating media. They have become the preferred material for ceramic bearings and hybrid ceramic ball bearings. After production, they need to be cleaned to ensure the smoothness of the surface. A new type of automatic cleaning device for silicon nitride ceramic balls is disclosed in the Chinese utility model patent with announcement number CN213826163U. It can efficiently and in large quantities transmit silicon nitride ceramic balls through the action of a longitudinal transmission mechanism. It can ensure the cleaning quality through the action of a transverse cleaning mechanism while avoiding rigid contact with the silicon nitride ceramic balls and avoiding damage to the silicon nitride ceramic balls. In the above structure, the conical brush rolls back and forth from left to right. The silicon nitride ceramic ball is placed between two adjacent rubber baffles on a conveyor belt. There is no corresponding positioning structure in the middle. When the conical brush is rolling, it will push the silicon nitride ceramic ball to roll in the direction of movement below the conical brush, which will cause multiple silicon nitride ceramic balls to pile up together. The conical brush can only clean the upper part. Therefore, we designed a cleaning device for the production of silicon nitride ceramic balls. Utility Model Content

[0004] The utility model is implemented by the following technical scheme: a cleaning device for silicon nitride ceramic ball production, comprising two symmetrically arranged frames, a plurality of linearly distributed conveying rollers are rotatably mounted between the two frames through bearings, a conveying belt is tensioned on the conveying roller, a plurality of evenly distributed embedding grooves are formed through the upper and lower surfaces of the conveying belt, and a ball seat is arranged on the inner side of each embedding groove;

[0006] As a further improvement of the above scheme, the rear ends of the multiple shower pipes are connected to the water distribution pipes, and the water distribution pipes are welded with a water inlet main pipe, which is used to connect to an external water pump and a water tank. Clean water can enter the multiple shower pipes through the water inlet main pipe and the water distribution pipe, and then can flush the silicon nitride ceramic balls below through the shower holes below.

[0007] As a further improvement of the above scheme, the front end of the cleaning brush passes through the front mounting plate and is placed in front of it, and the front ends of the three cleaning brushes are connected to the output shaft of the cleaning motor through a toothed belt wheel and a toothed belt, and the three cleaning brushes can rotate synchronously, thereby being able to clean the silicon nitride ceramic ball below;

[0009] As a further improvement of the above scheme, a plurality of support rings with equal spacing are arranged on the conveying roller, the conveying belt is tensioned on the support ring, an embedding groove and a corresponding ball placement seat are arranged between every two adjacent support rings, the silicon nitride ceramic ball can be placed inside the ball placement seat, and the upper and lower sides of the conveying belt are placed above and below it respectively, and the center of the silicon nitride ceramic ball is located in the embedding groove.

[0011] As a further improvement of the above scheme, a storage box is arranged at the upper right end of the frame, the bottom end of the storage box is connected to the top of the conveyor belt, and a movable notch is opened on the left side of the storage box. The height between the movable notch and the conveyor belt is smaller than the diameter of the silicon nitride ceramic ball. After the silicon nitride ceramic ball is placed inside the ball seat, the top of the silicon nitride ceramic ball is below the movable notch, thereby facilitating the movement of the silicon nitride ceramic ball.

[0022] Example:

[0023] Please combine Figure 1-Figure 4 The present embodiment is a cleaning device for producing silicon nitride ceramic balls, comprising two symmetrically arranged frames 1, a plurality of linearly distributed conveying rollers 2 are rotatably mounted between the two frames 1 through bearings, a conveying belt 3 is tensionedly arranged on the conveying rollers 2, a plurality of evenly distributed embedding grooves 31 are formed through the surface of the conveying belt 3 from top to bottom, and a ball seat 8 is arranged on the inner side of each embedding groove 31;

[0024] A mounting plate 5 is arranged above the frame 1, and three cleaning brushes 7 with equal spacing are rotatably mounted between the two mounting plates 5 through bearings, and a plurality of shower pipes 6 are linearly distributed between the two mounting plates 5, and a plurality of shower holes with equal spacing are opened below the outer ring surface of the shower pipe 6.

[0025] The rear ends of the multiple shower pipes 6 are all connected to the water distribution pipe 61, and a water inlet main pipe 62 is welded on the water distribution pipe 61. The water inlet main pipe 62 is used to connect to an external water pump and a water tank. Clean water can enter the multiple shower pipes 6 through the water inlet main pipe 62 and the water distribution pipe 61, and then can flush the silicon nitride ceramic balls below through the shower holes below.

[0026] The front end of the cleaning brush 7 passes through the front mounting plate 5 and is placed in front of it, and the front ends of the three cleaning brushes 7 are connected to the output shaft of the cleaning motor through a toothed belt wheel and a toothed belt, so that the three cleaning brushes 7 can rotate synchronously, thereby being able to clean the silicon nitride ceramic ball below;

[0027] The rear ends of the multiple conveyor rollers 2 pass through the rear frame 1 and are placed on the rear side thereof, and the rear ends of the multiple conveyor rollers 2 are connected by sprockets and chains, and the front side of the rightmost conveyor roller 2 is connected to the output shaft of the driving motor through a toothed belt wheel and a toothed belt, so that the multiple conveyor rollers 2 can rotate, thereby moving the conveyor belt 3 above.

[0028] A plurality of support rings 21 are arranged on the conveying roller 2 at equal intervals, and the conveying belt 3 is tensioned on the support rings 21. An embedding groove 31 and a corresponding ball placement seat 8 are arranged between every two adjacent support rings 21. The silicon nitride ceramic ball can be placed inside the ball placement seat 8, and the upper and lower sides of the conveying belt 3 are placed above and below it respectively. The center of the silicon nitride ceramic ball is located in the embedding groove 31, and the bottom of the silicon nitride ceramic ball does not contact the conveying roller 2, so as to facilitate the leftward movement of the silicon nitride ceramic ball.

[0029] The opening of the ball seat 8 gradually decreases from top to bottom, and the center of the ball seat 8 is colinear with the axle pin of the embedding groove 31. The bottom end of the ball seat 8 is above the outer ring surface of the conveying roller 2, and the silicon nitride ceramic ball can be rolled into the ball seat 8 and can roll.

[0030] A storage box 4 is arranged at the upper right end of the frame 1, the bottom end of the storage box 4 is connected to the top of the conveyor belt 3, and a movable notch 41 is opened on the left side of the storage box 4. The height between the movable notch 41 and the conveyor belt 3 is smaller than the diameter of the silicon nitride ceramic ball. After the silicon nitride ceramic ball is placed inside the ball seat 8, the top of the silicon nitride ceramic ball is located below the movable notch 41, thereby facilitating the movement of the silicon nitride ceramic ball.

[0031] The implementation principle of a cleaning device for silicon nitride ceramic ball production in the embodiment of the present application is as follows: a plurality of silicon nitride ceramic balls are placed inside a storage box 4, and then the water inlet main pipe 62 is connected to an external water pump and a water tank, and clean water can enter the plurality of shower pipes 6 through the water inlet main pipe 62 and the water distribution pipe 61, and then the silicon nitride ceramic balls below can be rinsed through the shower holes below, and the power supply of the cleaning motor and the driving motor is turned on. The conveyor belt 3 will move from right to left under the action of the plurality of conveyor rollers 2, and the three cleaning brushes 7 will also rotate counterclockwise (that is, the rotation direction of the cleaning brush 7 is opposite to the movement direction of the conveyor belt 3). Due to the storage box 4 A moving notch 41 is provided on the left side, and the height between the moving notch 41 and the conveyor belt 3 is less than the diameter of the silicon nitride ceramic ball. The silicon nitride ceramic ball will fall into the ball holder 8 and move with the conveyor belt 3, so that the silicon nitride ceramic ball can continuously move to the left. When the silicon nitride ceramic ball moves to the bottom of the cleaning brush 7 and the shower pipe 6, since the rotation direction of the cleaning brush 7 is opposite to the movement direction of the conveyor belt 3, the cleaning brush 7 can also push the silicon nitride ceramic ball to rotate to a certain extent while cleaning the left surface of the silicon nitride ceramic ball, thereby being able to clean its surface in all directions, and will fall and be collected when it moves to the leftmost end;

[0032] By providing an embedding groove 31 and a ball seat 8 for the silicon nitride ceramic ball to roll on the conveying roller 2, and cooperating with a cleaning roller that rotates in the opposite direction, the left surface of the silicon nitride ceramic ball can be cleaned while rotating to a certain extent, thereby being able to clean its surface in all directions;

[0033] By arranging a storage box 4 at the right end above the frame 1, in conjunction with the movable notch 41 and the conveyor belt 3, the silicon nitride ceramic balls can continuously move to the left, thereby improving the cleaning efficiency.
