[0002] A sand mill is a grinding equipment that enables continuous processing and discharge of materials. It is widely used in industries such as paints, cosmetics, dyes, and inks. To improve the grinding effect, a filtration process is required during feeding to separate out large particles in the material, thereby ensuring production quality.

[0003] Existing sand mill filtration devices rely on gravity for natural filtration and screening of materials. However, this process is slow due to material tending to clump together in the center and the inherent gravity of the material, thus affecting screening efficiency. To address these issues, we provide a sand mill feed filtration device. Utility Model Content

[0007] The present invention is further configured such that a rectangular plate is hinged to the outer wall of the arc-shaped plate, and a first guide groove is provided on both inner sides of the rectangular plate, and a second guide groove is provided on the top of the base.

[0008] The present invention is further configured such that the lifting assembly includes a cylinder fixedly connected to the top of the base, a horizontal plate fixedly connected to the output end of the cylinder, a sliding plate slidably connected to the second guide groove fixedly connected to one side of the horizontal plate, a straight toothed plate fixedly connected to the top of the sliding plate, and a stop rod fixedly connected to the top of the straight toothed plate.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] For a specific implementation example, please refer to Implementation Example 1. Figure 1-9This utility model is a feeding and filtering device for a sand mill, including a screening component 1; the screening component 1 includes a base 101, a collection box 102 is fixedly connected to the top of the base 101, a plurality of sleeves 103 are rotatably connected to the top of the collection box 102, insert rods 104 are slidably connected inside the sleeves 103, a screening box 105 is fixedly connected between the plurality of insert rods 104, a first arc-shaped groove 106 is provided on the outer wall of the screening box 105, an arc-shaped toothed plate 107 is fixedly connected inside the first arc-shaped groove 106, an arc plate 108 is fixedly connected between two adjacent insert rods 104, and a second arc-shaped groove 109 is provided at the bottom of the arc plate 108; a lifting component 2 is provided on the top of the base 101, the lifting component 2 includes a first sliding rod 201 slidably connected inside the second arc-shaped groove 109, and a bending plate 202 is fixedly connected to the bottom end of the first sliding rod 201.

[0030] The screening assembly 1 also includes a control box 110 fixedly connected to the top of the base 101. The top of the collection box 102 is provided with a first annular groove 111. The first annular groove 111 is provided with arc-shaped sliding grooves 112 on both inner walls. The outer wall of the sleeve 103 is symmetrically fixedly connected with a second sliding rod 113 that is slidably connected to the two arc-shaped sliding grooves 112. The bottom of the screening box 105 is fixedly connected with a conical guide plate 114. The outer wall of the conical guide plate 114 and the bottom of the screening box 105 are evenly provided with a plurality of screen holes 115. The outer wall of the arc plate 108 is hinged with a rectangular plate 116. The rectangular plate 116 is provided with a first guide groove 117 on both inner sides. The top of the base 101 is provided with a second guide groove 118.

[0031] The operation process of this embodiment is as follows: First, the arc-shaped toothed plate 107 is controlled to reciprocate, so that the arc-shaped toothed plate 107 drives the screening box 105 to reciprocate. Then, the material is put into the screening box 105. Through the reciprocating rotation of the screening box 105 in the horizontal direction, the material is constantly shaken, thereby accelerating the rapid screening of the material inside the screening box 105. By setting a conical guide plate 114 inside the screening box 105, the material is dispersed from the top of the conical guide plate 114 along its outer wall, thereby avoiding the material from piling up in the middle of the screening box 105, which would affect the screening effect and screening efficiency. At the same time, by controlling the bending plate 202 to reciprocate up and down, the first slide rod 201 drives the insertion rod 104 to reciprocate up and down, thereby driving the screening box 105 to reciprocate up and down, so that the screening box 105 drives the material inside to continuously turn over in the vertical direction, further improving the screening efficiency.

[0032] By controlling the screening box 105 to rotate back and forth in the horizontal direction and to move back and forth up and down in the vertical direction, the screening box can shake the material at mutually perpendicular angles, thereby speeding up the screening speed and improving the screening efficiency.

[0033] For a specific embodiment two, please refer to Figure 1-9 Based on the first specific embodiment, the lifting assembly 2 also includes a cylinder 203 fixedly connected to the top of the base 101. A horizontal plate 204 is fixedly connected to the output end of the cylinder 203. A sliding plate 205 that is slidably connected to the second guide groove 118 is fixedly connected to one side of the horizontal plate 204. A straight toothed plate 206 is fixedly connected to the top of the sliding plate 205. A stop rod 207 is fixedly connected to the top of the straight toothed plate 206. The lifting assembly 2 also includes a guide rod 208 fixedly connected to the top of the base 101. The guide rod 208 is slidably connected to the bending plate 202. A support plate 209 located below the bending plate 202 is fixedly connected to the outer wall of the guide rod 208. A baffle 210 is fixedly connected to the top of the guide rod 208. A wedge block 211 that abuts against the stop rod 207 is fixedly connected to one side of the bending plate 202.

[0034] The operation process of this embodiment is as follows: the horizontal plate 204 is moved back and forth horizontally by the control cylinder 203, and then the straight tooth plate 206 is moved back and forth by the slide plate 205, which in turn drives the abutment rod 207 to move back and forth. The abutment rod 207 moves towards the wedge block 211, so that the abutment rod 207 touches the wedge block 211 and moves upward. The abutment rod 207 moves away from the wedge block 211. Under the pressure of the screening box 105, the wedge block 211 moves downward. Through the back and forth up and down movement of the wedge block 211, the bending plate 202 is driven to move back and forth up and down, providing power for the movement of the bending plate 202.

[0035] For a specific embodiment three, please refer to Figure 1-9 Based on specific embodiments one and two, a transmission assembly 3 is rotatably connected to the top of the base 101. The transmission assembly 3 includes a sleeve 301 rotatably connected to the top of the base 101. A rotating shaft 302 is slidably connected to the inner wall of the sleeve 301. Limiting grooves 303 are symmetrically opened on the inner wall of the sleeve 103. A slider 304 that is slidably connected to the two limiting grooves 303 is symmetrically fixed to the outer wall of the rotating shaft 302. A first spur gear 305 that meshes with the spur gear plate 206 is fixedly connected to the outer wall of the sleeve 301. A disc 306 that is slidably connected to the first guide groove 117 is fixedly connected to the outer wall of the rotating shaft 302. A second spur gear 307 that meshes with the arc-shaped toothed plate 107 is fixedly connected to the top of the rotating shaft 302. A PLC controller is provided inside the control box 110. The PLC controller is electrically connected to the cylinder 203.

[0036] The operation process of this embodiment is as follows: By controlling the reciprocating movement of the spur gear 206, the spur gear 206 drives the first spur gear 305 meshing with it to reciprocate, thereby driving the sleeve 301 to reciprocate. Through the insertion and engagement of the slider 304 and the limiting groove 303, the sleeve 301 further drives the rotating shaft 302 to reciprocate, thereby driving the second spur gear 307 to reciprocate, causing the second spur gear 307 to drive the arc-shaped gear plate 107 meshing with it to reciprocate. The rotation provides power for the reciprocating rotation of the arc-shaped toothed plate 107. At the same time, during the reciprocating rotation of the screening box 105, the screening box 105 drives the arc-shaped plate 108 and the rectangular plate 116 to reciprocate, causing the disc 306 on the rotating shaft 302 to slide in the first guide groove 117 on the rectangular plate 116. This ensures that the rotating shaft 302 and the screening box 105 move synchronously in the vertical direction, thereby ensuring that the second spur gear 307 and the arc-shaped toothed plate 107 are always in a meshing state.
