Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, specifically a sand mill with quantitative feeding. Background Technology

[0002] Sand mills primarily grind materials through the friction and collision of grinding media within the grinding cylinder. In ink production, sand mills are widely used for the dispersion and refinement of color pastes, ensuring that pigments in the ink are fully dispersed, guaranteeing ink stability and color effects. During operation, a transfer pump is typically used to deliver liquid materials into the sand mill while simultaneously sending liquid materials out of the mill, creating a circulation between the storage tank and the sand mill for continuous grinding and dispersion. However, re-transferring the ground liquid materials back to the storage tank may result in some liquid materials remaining there, requiring a longer grinding time. Furthermore, continuous feeding and unloading may lead to variations in the liquid volume within the mill due to excessive feeding or unloading. Conversely, excessive liquid in the mill can cause over-diluted materials during sand milling, affecting pigment dispersion and grinding efficiency. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] Please see Figure 1-4 In this embodiment of the utility model, a quantitative feeding sand mill includes a feeding module 100 and a machine body 200.

[0035] The feeding module 100 is capable of feeding materials. The feeding module 100 includes a material cylinder 110. A partition 140 is provided on the inner side of the material cylinder 110. A washer 141 is rotatably connected to the side of the partition 140 and slidably connected to the side of the material cylinder 110. A plurality of opening slots 142 are opened on the top surface of the partition 140. A plurality of baffles 144 are slidably connected to the inner side of the partition 140 corresponding to the opening slots 142. A fixed plate 160 is fixedly connected inside the material cylinder 110. A sliding plate 170 is slidably connected to the inner side of the material cylinder 110. The fixed plate 160 is located between the partition 140 and the sliding plate 170. A plurality of circular grooves 161 are opened on the top surface of the fixed plate 160. A one-way valve is provided inside the circular grooves 161. The machine body 200 is located on one side of the feeding module 100.

[0036] A connecting seat 143, which is fixedly connected to the side of several baffles 144, is rotatably connected to the inner side of the partition 140. Limit seats 180 are rotatably connected to the inner sides of both the fixed plate 160 and the sliding plate 170. A drive mechanism 150 is provided on the material cylinder 110. A conveying frame 130 is fixedly connected to the bottom and top surfaces of the side of the material cylinder 110. A conveying pump is installed inside the conveying frame 130. A conveying pipe 131 and a fixed pipe 132, which communicate with the conveying pump, are provided on the side of the conveying frame 130. The bottom fixed pipe 132 corresponds to the fixed plate 160. 0. The fixed plate 160 has a notch corresponding to the fixed pipe 132. The ends of the two conveying pipes 131 are connected to the machine body 200, and the ends of the two fixed pipes 132 are connected to the material cylinder 110. The bottom conveying pump can suck up the liquid material in the adjacent fixed pipe 132, and then transport the liquid material to the machine body 200 through the bottom conveying pipe 131. The top conveying pump can suck up the liquid material in the machine body 200 through the top conveying pipe 131, and then transport the liquid material to the inside of the material cylinder 110 through the top fixed pipe 132.

[0037] Specifically, the baffle 144 can be rotated to block the corresponding opening slot 142, and the partition 140 can be moved downwards, allowing a certain amount of liquid to pass through the circular groove 161 and the one-way valve into the space between the fixed plate 160 and the sliding plate 170. The one-way valve can prevent the liquid from flowing back to the top of the fixed plate 160. Then, the liquid between the fixed plate 160 and the sliding plate 170 can be transported to the inside of the machine body 200 by the bottom conveying pump, thereby quantitatively adding material into the machine body 200 and avoiding excessive liquid inside the grinder from affecting the grinding effect. The partition 140 and the baffle 144 separate the inside of the material cylinder 110 vertically. The ground liquid can be transported to the top of the gasket ring 141 by the top conveying pump, while the unground liquid is located at the bottom of the partition 140, thereby preventing the liquid from mixing with each other and allowing some liquid to remain inside the material cylinder 110, which helps to reduce the grinding time.

[0038] After the liquid material at the bottom of the partition 140 is gradually transported into the machine body 200, when the partition 140 moves to the top of the fixed plate 160, the baffle 144 can rotate inside the partition 140, causing the baffle 144 to retract into the partition 140, thereby dislocating the baffle 144 from the opening groove 142. At this time, the partition 140 can be moved upward, so that the liquid material can flow through the opening groove 142 to the bottom of the partition 140. Then, the baffle 144 can block the opening groove 142 again, and the partition 140 can be moved downward again for the next grinding, which is beneficial for continuous grinding of the liquid material.

[0039] A discharge pipe can be installed at the bottom of the material cylinder 110, and a feed pipe can be installed at the top of the material cylinder 110. Material is added into the material cylinder 110 through the feed pipe, and the ground liquid material is discharged through the discharge pipe.

[0040] Example 1

[0041] like Figure 2 As shown, in this embodiment, a plurality of support columns 111 are fixedly connected to the bottom surface of the material cylinder 110. The support columns 111 can support the material cylinder 110. A sliding rod 112, which is fixedly connected to the bottom surface of the sliding plate 170, is slidably connected to the inner side of the support column 111. A return spring 113, which is fixedly connected to the inner side of the support column 111, is fixedly connected to the inner side of the sliding rod 112. Under the action of the return spring 113, the position of the sliding rod 112 is maintained, thereby maintaining the position of the sliding plate 170.

[0042] In practice, when the liquid material passes through the circular groove 161 and the one-way valve, the sliding plate 170 can be squeezed, causing the sliding plate 170 to move downward. When the bottom conveying pump draws the liquid material between the fixed plate 160 and the sliding plate 170, under the action of the return spring 113, the sliding rod 112 and the sliding plate 170 can be moved upward to their original positions, so that the top surface of the sliding plate 170 is in contact with the bottom surface of the fixed plate 160. By blocking the circular groove 161 through the sliding plate 170, it is beneficial to quantitatively feed the machine body 200.

[0043] like Figure 3 As shown, in this embodiment, an adjustment mechanism 120 is provided on the side of the material cylinder 110;

[0044] The adjusting mechanism 120 includes two fixed seats 121, two hydraulic rods 122, two adjusting rods 124, and a connecting rod 123. The two fixed seats 121 are fixedly connected to the side of the material cylinder 110. The two hydraulic rods 122 are respectively fixedly connected to the inner side of the two fixed seats 121. The fixed seats 121 can protect the bottom of the hydraulic rods 122. The two adjusting rods 124 are slidably connected to the inner side of the material cylinder 110. The bottom end of the adjusting rod 124 is fixedly connected to the top surface of the washer 141. The connecting rod 123 is fixedly connected to the top of the two adjusting rods 124. The output ends of the two hydraulic rods 122 are drivenly connected to the bottom surface of the connecting rod 123. The hydraulic rods 122 can support the connecting rod 123. The connecting rod 123 can limit the position of the washer 141 through the adjusting rods 124, thereby limiting the height of the partition 140.

[0045] In practice, the connecting rod 123 can be moved up or down by the hydraulic rod 122. The connecting rod 123 can drive the two adjusting rods 124 to move. The adjusting rods 124 can drive the washer ring 141 to move. The washer ring 141 can drive the partition plate 140 to move up or down, thereby adjusting the position of the partition plate 140. The partition plate 140 can be moved a fixed distance by the hydraulic rod 122, so that the partition plate 140 can squeeze a certain amount of liquid material between the fixed plate 160 and the sliding plate 170.

[0046] Example 2

[0047] Based on Example 1, such as Figure 2 As shown, in this embodiment, the drive mechanism 150 includes a fixed box 151, a drive motor 152, a drive shaft 153, two rotating seats 154, and several positioning rods 155.

[0048] The fixed box 151 is fixedly connected to the bottom surface of the material cylinder 110. The drive motor 152 is fixedly connected to the inner bottom surface of the fixed box 151. The drive shaft 153 is rotatably connected to the inner side surface of the fixed box 151, and the output end of the drive motor 152 is connected to the bottom end of the drive shaft 153. Two rotating seats 154 are rotatably connected to the top and bottom of the inner side surface of the material cylinder 110, respectively. The top end of the drive shaft 153 is fixedly connected to the bottom surface of the rotating seat 154. Several positioning rods 155 are fixedly connected to the opposite surfaces of the two rotating seats 154. The inner side surface of the connecting seat 143 is slidably connected to the sides of the several positioning rods 155, and the inner sides of the two limiting seats 180 are slidably connected to the sides of the several positioning rods 155. The connecting seat 143 and the limiting seat 180 can slide relative to the positioning rods 155, thereby causing the partition 140 to rotate and slide relative to the positioning rods 155.

[0049] In a specific implementation, the drive motor 152 can drive the drive shaft 153 to rotate, the drive shaft 153 can drive the bottom rotating seat 154 to rotate, the rotating seat 154 can drive a number of positioning rods 155 to rotate, the number of positioning rods 155 can drive the connecting seat 143 to rotate, thereby causing the connecting seat 143 to drive the baffle 144 to rotate within the partition 140, so that the baffle 144 blocks the opening slot 142, or makes the baffle 144 and the opening slot 142 misaligned;

[0050] A damper can be optionally provided between the partition 140 and the washer 141, so that the partition 140 is prevented from rotating arbitrarily by the washer 141. This allows the baffle 144 to rotate smoothly relative to the partition 140, so that the baffle 144 corresponds to or is offset from the opening slot 142. Alternatively, the partition 140 can be directly fixed inside the washer 141, so that the partition 140 is prevented from rotating by the washer 141, thereby allowing the baffle 144 to rotate smoothly relative to the partition 140.

[0051] like Figure 3 and Figure 5 As shown, in this embodiment, a stirring frame 145 is provided at the top and bottom of the inner side of the opening groove 142. A fixed shaft 146 is rotatably connected to the inner side of the stirring frame 145 and fixedly connected to the inner side of the opening groove 142. A torsion spring 147 is provided between the side of the fixed shaft 146 and the inner side of the stirring frame 145. Under the action of the torsion spring 147, the angle of the stirring frame 145 can be maintained.

[0052] In specific implementation, after the baffle 144 is rotated into the opening slot 142 and the opening slot 142 is blocked by the baffle 144, the connecting seat 143 can continue to rotate through the positioning rod 155. The connecting seat 143 pushes the partition 140 to rotate through the baffle 144, so that the partition 140 rotates in the gasket 141. The partition 140 can drive the stirring frame 145 to rotate. In this way, the stirring frame 145 can continuously stir the liquid material to perform preliminary mixing and avoid the accumulation of particles in the liquid material. When the partition 140 moves to the top surface of the fixed plate 160, the fixed plate 160 can squeeze the stirring frame 145 to rotate into the opening slot 142. When the partition 140 moves away from the fixed plate 160, the stirring frame 145 can rotate back to its original angle under the action of the torsion spring 147.

[0053] When the partition 140 is fixed inside the gasket 141, the stirring frame 145 can be rotatably mounted on the baffle 144. When the partition 140 is moved upward again to allow the liquid to flow to the bottom of the partition 140, the positioning rod 155 is rotated back and forth by the drive motor 152, thereby causing the stirring frame 145 to move back and forth in the liquid to stir the liquid.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
