[0001] This utility model relates to the technical field of grinding wheel manufacturing equipment, specifically a grinding wheel manufacturing sieve device. Background Technology

[0002] A grinding wheel is a tool used for grinding operations, typically composed of abrasive grains, a bonding agent, and pores. During manufacturing, abrasive particles are mixed with a bonding agent, and then formed into a grinding wheel of a specific shape through processes such as pressing and sintering. Grinding wheels are mainly used for grinding, cutting, deburring, and polishing of metallic or non-metallic materials, and have wide applications in machining, automotive manufacturing, aerospace, and precision instrument manufacturing. In the manufacturing process of grinding wheels, raw materials need to be sieved to ensure that the particle size of the raw materials meets production requirements, thereby ensuring the quality of the grinding wheels.

[0018] 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.

[0019] like Figures 1 to 4 As shown, this utility model provides a sieving device for making grinding wheels, including a device body, the device body including a frame 1, a collection trough 11 is provided on one side of the frame 1, and a sieving component 2 is provided on the frame 1.

[0020] The screening assembly 2 includes a support frame 21 mounted on one end of the upper surface of the frame 1. A screening box 22 is hinged to the surface of the support frame 21. Three detachable screening plates 23 are arranged in the groove of the screening box 22. The surface of each screening plate 23 is provided with filter holes. A geared motor 24 is installed on the surface of the frame 1 below the screening box 22. The output end of the geared motor 24 is connected to a rotating wheel 25 located at the bottom of the screening box 22. The surface of the rotating wheel 25 is provided with a protrusion that abuts against the bottom surface of the screening box 22. The discharge port of the screening box 22 is located above the collection trough 11. By setting up the geared motor 24, the rotating wheel 25 and the protrusion, the screening box 22 can be driven to vibrate. Combined with the inclined groove of the screening box 22 and the arc-shaped screening plates 23, the screening efficiency and effect of raw materials are greatly improved.

[0021] The groove of the screening box 22 is set with an inclined structure. This inclined structure helps the raw materials to flow in the screening box 22 and improves the screening efficiency.

[0022] The sieve holes on the surface of the three sieve plates 23 are arranged with progressively smaller diameters. By using sieve holes of different diameters, raw materials can be graded and sieved to meet the needs of different particle sizes.

[0023] The screening plate 23 has an arc-shaped structure, and a sliding groove is provided on the side of the screening plate 23 that fits into the groove of the screening box 22. The inner walls of the groove of the screening box 22 are equipped with locking protrusions at corresponding positions on both sides. The sliding groove and the locking protrusions are matched. The arc-shaped screening plate 23 can increase the contact area between the raw material and the screening plate 23, thereby improving the screening effect. The cooperation between the sliding groove and the locking protrusions makes it easy to disassemble and install the screening plate 23, which is convenient for later cleaning and replacement.

[0024] A feeding mechanism 3 is provided above the support frame 21. The feeding mechanism 3 includes a feeding box 31 located above the screening box 22. A filter screen is installed at the bottom of the feeding box 31. A tapered guide pipe 32 is provided below the feeding box 31. Two fixed seats 33 are mounted on the surface of the support frame 21. A guide sleeve 34 is installed above the fixed seats 33. Two sliding rods 35 are symmetrically installed at the bottom of the feeding box 31 through a connecting plate. One end of the sliding rod 35 is inserted into the guide sleeve 34. The inner wall of the guide sleeve 34 is adapted to the sliding rod 35. The slide bar 35 is fitted with a spring 36, and the two ends of the spring 36 are connected to the guide sleeve 34 and the connecting plate, respectively. A vibrator is installed on the bottom surface of the feeding box 31. The filter screen can perform preliminary filtration of the raw materials entering the feeding box 31 to remove larger impurities. The vibrator can drive the feeding box 31 to vibrate. With the help of the spring 36 and the slide bar 35, the raw materials are prevented from clogging in the feeding box 31 and the feeding is ensured to be smooth. The tapered guide pipe 32 can accurately guide the raw materials into the screening box 22.

[0025] Three material distribution plates 4 are installed on the groove surface of the screening box 22 at the position of the material guide pipe 32. Two of the material distribution plates 4 are installed at an angle on the groove surface. The material distribution plates 4 can evenly distribute the raw materials introduced by the material guide pipe 32 onto the screening plates 23, avoid the accumulation of raw materials in the screening box 22, and improve the uniformity and efficiency of screening.

[0026] Working principle and process: When using this grinding wheel to make a screening device, firstly, the raw materials to be screened are placed into the feeding box 31. The filter screen in the feeding box 31 performs preliminary filtration of the raw materials, removing larger impurities. Then, the vibrator on the bottom of the feeding box 31 is activated. The vibrator drives the feeding box 31 to vibrate. Under the action of the spring 36 and the slide rod 35, the feeding box 31 vibrates up and down to prevent the raw materials from clogging. The raw materials enter the screening box 22 through the guide pipe 32.

[0027] The raw material discharged from the feed pipe 32 is evenly distributed onto the three screening plates 23 under the action of the distribution plate 4. The reduction motor 24 is started, driving the rotating wheel 25 to rotate. The protrusions on the surface of the rotating wheel 25 abut against the bottom surface of the screening box 22, thereby causing the screening box 22 to vibrate. Because the screening box 22 is hinged to the support frame 21, and the groove of the screening box 22 is inclined, the raw material flows downward along the groove of the screening box 22 under the action of vibration and its own gravity.

[0028] During the flow process, the raw material passes through three screening plates 23. As the sieve hole diameters of the three screening plates 23 decrease sequentially, the raw material is graded and screened. The raw material that meets the particle size requirements falls through the screening holes into the bottom of the screening box 22, and finally enters the collection tank 11 from the discharge port for collection.

[0029] When it is necessary to replace the screening plate 23, simply slide the screening plate 23 out along the chute from the locking protrusion of the screening box 22 for replacement or cleaning. The operation is convenient and quick.
