Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to a dust-proof structure for a ball mill used in coating production. Background Technology

[0002] Ball mills for paint production are key equipment in the paint industry for grinding and dispersing pigments. Their core structure is a drum that rotates around a horizontal axis and contains steel or ceramic grinding media. The rotation of the drum causes the media to collide and rub against the material, achieving impact grinding and shear dispersion, thereby uniformly refining the pigment to the required particle size. This equipment is highly adaptable and can process a variety of pigments, and is especially good at dispersing difficult-to-grind materials.

[0003] To facilitate material discharge, existing technologies typically install discharge gates directly on the outer wall of ball mills. These gates are opened by rotation or sliding. However, when the discharge gates are opened and the coating powder inside the drum is discharged, a large amount of dust is easily generated around the ball mill. This not only poses a safety hazard to the working environment of the equipment but also easily leads to material waste. Utility Model Content

[0007] The dustproof mechanism includes a hopper, a sealing frame is fixedly connected to the inner side of the top surface of the hopper, and upper bolts are symmetrically threaded to the outer wall of the sealing frame.

Handles are provided on both sides of the counterweight, and the operator can grasp the handles and shake them slightly, which helps the material adhering to the inner wall of the guide bag to fall, avoids material waste, and also reduces the cleaning difficulty of the dustproof mechanism.

Both the top and bottom ends of the guide bag 204 are provided with openings, and a counterweight 205 is fixedly connected to the middle of the outer wall of the guide bag 204. Handles 206 are fixedly connected to both sides of the counterweight 205. A discharge hopper 207 is fixedly and continuously connected to the bottom end of the guide bag 204, and several lower bolts 208 are continuously connected to the lower end of the outer wall of the discharge hopper 207. The bottom of the discharge hopper 207 is sealed and a paint collection box 209 is inserted into it. The upper end of the outer wall of the paint collection box 209 is threadedly connected to each of the lower bolts 208. Figure 2 As shown, a rubber sealing gasket is bonded to the outside of the sealing frame 202 to reduce the connection gap with the unloading frame 109. The collecting hopper 201, the discharging hopper 207 and the counterweight 205 can be made of stainless steel or plastic. When the guide bag 204 is damaged, it is easy to replace the whole thing.

[0030] The belt-driven ball mill 1 also includes a base plate 101. Limiting plates 102 are symmetrically fixedly connected to the center of the top surface of the base plate 101. The two limiting plates 102 are clamped and slidably connected to a paint collection box 209, and the top surface of the base plate 101 is slidably connected to the paint collection box 209. A first bracket 103 is fixedly connected to one side of the top surface of the base plate 101, and a second bracket 104 is fixedly connected to the other side of the top surface of the base plate 101. A first limiting bearing 105 is fixedly installed in the middle of the top of the first bracket 103. An upper drive wheel 116 is rotatably connected to the side of the first limiting bearing 105. The other end of the upper drive wheel 116 is fixedly connected to the center of the drum 108. A second limiting bearing 106 is also rotatably connected to the center of the side of the drum 108 away from the upper drive wheel 116. The outer wall of the second limiting bearing 106 is fixedly installed to the top of the second bracket 104. Figure 1 As shown, the top of the paint collection box 209 is provided with an opening, and a grate structure can be placed in the opening as needed, so as to facilitate the separate collection of grinding media in the falling material.

[0031] A discharge frame 109 is fixedly and continuously connected to the center of the bottom surface of the roller 108. An arc-shaped groove 110 is provided on the upper end of one side of the discharge frame 109. The lower ends of both sides of the discharge frame 109 are respectively connected to upper bolts 203. Threaded holes 111 are provided on the surface of the discharge frame 109 on both sides of the upper bolts 203. The lower end of the inner wall of the discharge frame 109 is sealed and inserted into the sealing frame 202. An arc-shaped baffle 112 is slidably connected to the inner side of the arc-shaped groove 110. A pull ring 113 is fixedly connected to the other end of the arc-shaped baffle 112. Connecting ears 114 are fixedly connected to the bottom surface of the arc-shaped baffle 112 on both sides of the pull ring 113. Figures 3-4 As shown, the fastener with the anti-slip washer is screwed into the threaded hole 111. The anti-slip washer can prevent the fastener from loosening when the roller rotates.

[0032] The lower end of the connecting ear 114 is on the same horizontal line as the threaded hole 111. A sealing gasket 115 is also glued and fixed to the top edge of the arc-shaped baffle 112. The top surface of the sealing gasket 115 abuts against the outer surface of the roller 108. A transmission belt 117 is installed on the outer side of the upper transmission wheel 116. A lower transmission wheel 118 is connected to the inner side of the lower end of the transmission belt 117.

Figure 5 As shown, according to actual production and transmission needs, the transmission belt 117 can be a synchronous toothed belt, and grooves for tooth meshing can be provided on the outer side of each transmission wheel structure that is in sync with the belt.

[0033] The working principle of this utility model:

[0034] When the device is in use, materials and grinding media can be fed into the drum 108 through the unloading frame 109. After the arc-shaped baffle 112 is inserted along the arc-shaped slide groove 110, the threaded hole 111 is aligned with the lower end through hole of the connecting ear 114. Then, fasteners such as screws that fit the anti-slip washer are tightened in the threaded hole 111. When the synchronous motor 107 starts, it drives the lower transmission wheel 118 to rotate. Through the transmission belt 117, the upper transmission wheel 116 and the drum 108 can be rotated, so that the grinding media can move in the drum 108 and grind and crush the materials.

[0035] When grinding is finished, the synchronous motor 107 drives the roller 108 to rotate until the unloading frame 109 faces downward. Then, the sealing frame 202 is inserted into the inside of the unloading frame 109 and locked with the upper bolt 203. The arc baffle 112 is moved along the arc-shaped slide 110, and the ground material and grinding media fall into the collection hopper 201. Then, the material falls along the guide bag 204 and finally enters the paint collection box 209. During this process, the operator can hold the handle 206 and shake it to ensure that no material adheres to the inside of the guide bag 204. Then, the lower bolt 208 can be removed and the paint collection box 209 can be taken out separately.

[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
