Description

Technical Field

[0001] This utility model relates to the field of polishing powder unloading, specifically an automatic unloading device for rare earth polishing powder. Background Technology

[0002] Polishing powder is an abrasive material used for surface treatment, mainly composed of abrasives of various hardnesses and binders. It plays a role in grinding, polishing, and deburring during surface treatment, improving the surface smoothness, flatness, and corrosion resistance of products. This is of great significance for improving product quality and extending product lifespan. To facilitate the feeding of polishing powder, a feeding device is needed. The "Unloading Device for a Rotary Kiln for Rare Earth Polishing Powder Calcination" disclosed in application number "202323388279.9" is an increasingly mature technology. It involves "absorbing and recovering heat from the unloading tank through a heat recovery pipe, circulating and heating water through a circulating pump connected to the heat recovery pipe and a water storage tank, and using a scale to collect the water from the unloading tank." The unloading device weighs rare earth polishing powder and uses a movable baffle and connecting rod to drive a servo motor for easy unloading. A vibrator is also used to increase the unloading speed. However, this unloading device has the following drawbacks: While the circulating pump and water tank facilitate unloading, the combination of these structures makes continuous feeding difficult, affecting efficiency. Therefore, a device that facilitates continuous feeding and improves efficiency is necessary. Furthermore, the device does not allow for proper stirring of the polishing powder, leading to powder accumulation. Therefore, a device that facilitates stirring and improves feeding smoothness is also necessary. Utility Model Content

[0022] Example 1

[0023] Please see Figures 1-4 This utility model provides an automatic unloading device for rare earth polishing powder, including a conveying component 100 and a stirring component 200;

[0024] The conveying assembly 100 includes a conveying pipe 101, a spiral conveying roller 102 rotatably connected inside the conveying pipe 101, a feeding pipe 103 fixedly connected to the lower end of the conveying pipe 101, a feeding pipe 104 fixedly connected to the upper end of the conveying pipe 101, a transmission mechanism 105 provided at one end of the spiral conveying roller 102, two transmission rollers 106 rotatably connected to the lower end of the conveying pipe 101, and a conveyor belt 107 connected between the two transmission rollers 106.

[0025] The mixing assembly 200 includes a feeding cylinder 201, a drive shaft 202 is rotatably connected inside the feeding cylinder 201, a number of mixing blades 203 are fixedly connected to the side surface of the drive shaft 202, a screen 204 is installed inside the feeding cylinder 201, and a second motor 205 is installed at the upper end of the drive shaft 202.

[0026] In one specific embodiment, the combination of the conveying component 100 and the stirring component 200 not only facilitates the avoidance of blockage during polishing powder feeding and improves the unloading smoothness of the unloading device, but also facilitates continuous feeding of polishing powder, thereby improving unloading efficiency. In use, the polishing powder is first placed in the feeding cylinder 201, and the second motor 205 is started to rotate the drive shaft 202, which in turn rotates several stirring blades 203 on the side surface, thereby automatically stirring the polishing powder and preventing it from accumulating and blocking. When the polishing powder enters the conveying pipe 101, the transmission mechanism 105 is started to rotate the spiral conveying roller 102, thereby conveying the polishing powder onto the upper end of the conveyor belt 107. Then, the polishing powder can be conveyed by an external motor rotating one of the drive shafts 202, thereby improving the unloading efficiency of the unloading device.

[0027] Please see Figure 2 and Figure 3 The lower end of the conveying pipe 101 is fixedly connected to a bracket 111, which is made of cast aluminum.

[0028] In one specific embodiment, the bracket 111 made of cast aluminum can reduce its own weight while ensuring its own strength, thereby improving the installation stability of the delivery pipe 101.

[0029] Please see Figure 2 and Figure 3 A mounting frame 121 is installed at the lower end of the conveying pipe 101, and two drive rollers 106 are rotatably connected between the mounting frame 121.

[0031] Please see Figure 2 and Figure 3 The transmission mechanism 105 includes a first motor 1051 installed at one end of the conveying pipe 101, a synchronous pulley 1052 at one end of the spiral conveying roller 102 and at the output end of the first motor 1051, and a synchronous belt 1053 between the two synchronous pulleys 1052.

[0032] In one specific embodiment, the first motor 1051 is started to rotate one of the synchronous pulleys 1052, and the synchronous belt 1053 can rotate the other synchronous pulley 1052, so as to rotate the spiral conveyor roller 102 to stably convey the polishing powder.

[0033] Please see Figure 4 The upper end of the drive shaft 202 is provided with a limiting hole 211, and the output end of the second motor 205 is provided with a limiting shaft 212, which is inserted into the inside of the limiting hole 211.

[0035] Please see Figure 4 The feed cylinder 201 is equipped with a fixed frame 221 inside, and the drive shaft 202 is rotatably connected inside the fixed frame 221.

[0036] In one specific embodiment, the mounting bracket 221 can enhance the installation stability of the drive shaft 202, thereby facilitating the stable rotation of the polishing powder.

[0037] Please see Figure 4 The 204 sieve is made of stainless steel.

[0038] In one specific embodiment, the stainless steel screen 204 can prevent rust, thereby extending the service life of the screen 204.

[0039] Working principle: In use, polishing powder is first placed in the feeding cylinder 201. At the same time, the second motor 205 is started, which drives the transmission shaft 202 to rotate, thereby rotating several stirring blades 203 on the side surface. This automatically stirs the polishing powder, thus preventing it from accumulating and clogging. When the polishing powder enters the conveying pipe 101, the transmission mechanism 105 is started, which drives the spiral conveying roller 102 to rotate, thus conveying the polishing powder onto the upper end of the conveyor belt 107. Subsequently, an external motor drives one of the transmission shafts 202 to rotate, thereby conveying the polishing powder and improving the unloading efficiency of the unloading device.
