Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, specifically to an automatic feeding mechanism for a grinding mill. Background Technology

[0002] A grinding mill is a mechanical device that grinds lumpy or granular materials into powder. It uses mechanical force to subject the material to compression, impact, and shearing within the grinding chamber, thereby achieving the purpose of crushing and grinding. Equipment used for mass production is usually equipped with a feeding mechanism to improve processing efficiency.

[0003] Existing technology, such as publication number CN217910587U, provides a rubber mill feeding mechanism for asphalt modified powder production, including a grinding box, a feeding funnel inside the grinding box, a double-roll mill assembly below the feeding funnel, a feeding lifting box on one side of the grinding box, a bucket elevator inside the feeding lifting box, a feeding port on one side of the bottom of the feeding lifting box, a return port communicating with the grinding box on the other side of the bottom of the feeding lifting box, and through holes communicating with the feeding funnel on the top sidewalls of the feeding lifting box and the grinding box. A guide filter screen adapted to the return port is located below the double-roll mill assembly inside the grinding box. This utility model's rubber mill feeding mechanism for asphalt modified powder production belongs to the field of asphalt modified powder production technology. By connecting the feeding lifting box to a closed grinding box, the material is conveyed into the grinding box, preventing dust from drifting to the outside and avoiding air pollution.

[0004] The current design uses a bucket elevator to automatically feed materials into the discharge port, with a stirring rod inside to prevent blockage. However, in practice, inconsistent particle sizes can lead to larger particles not being fully ground, resulting in coarse powder and affecting product quality. For example, in flour production, unscreened wheat entering the mill can introduce barley grains or impurities, making the flour less fine and affecting the texture and appearance of pasta. Therefore, we propose an automatic feeding mechanism for the flour mill. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic feeding mechanism for a grinding mill. This automatic feeding mechanism solves the problem that when the particle size of the material is inconsistent, if the particle size difference is large, large particles may not be fully ground during grinding, resulting in coarse particles in the ground powder, which affects the product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic feeding mechanism for a grinding mill includes a grinding mill body, a feed inlet fixedly connected to the top of the grinding mill body, a support frame fixedly connected to the back of the grinding mill body, and the support frame extending into the inside of the feed inlet. A conveyor belt is connected to the support frame, and an adjustment mechanism is provided at the position of the support frame above the conveyor belt.

[0008] The adjustment mechanism includes a support base, which is fixedly connected to the top of the support frame at the lower position. The top of the support base has a circular groove, and a discharge port is opened at the position of the circular groove corresponding to the position of the conveyor belt. A feeding bin is fixedly connected to the top of the support base above the circular groove.

[0009] Preferably, a support plate is fixedly connected to the top of the feeding hopper, an electric telescopic rod is fixedly connected to the bottom of the support plate, and a baffle is fixedly connected to the bottom of the electric telescopic rod.

[0010] Preferably, a pusher plate is rotatably connected to the bottom of the inner wall of the circular groove, and a motor is fixedly connected to the bottom of the support base via a support frame to drive the pusher plate to rotate.

[0011] Preferably, the circular groove is provided with a distribution mechanism at the discharge port position, the distribution mechanism including a guide frame, the guide frame being fixedly connected to the support base at the position below the discharge port.

[0012] Preferably, the inner wall of the guide frame is slidably connected to a sliding frame via a limiting rod. The sliding frame has a material distribution port near the conveyor belt. Elastic strips are fixedly connected to both sides of the sliding frame, and the elastic strips are fixedly connected to the corresponding side of the inner wall of the guide frame.

[0013] Preferably, a magnetic suction plate is connected to the bottom of the sliding frame, and a drive plate is slidably connected to the bottom of the guide frame at the position corresponding to the magnetic suction plate, and the drive plate and the magnetic suction plate are magnetically attracted to each other.

[0014] Preferably, the output shaft of the motor is fixedly fitted with a first gear, the outer wall of the first gear is meshed with a second gear, and the second gear is rotatably connected to the support base. The drive plate is provided with a sliding groove below the second gear, the inner wall of the sliding groove is slidably connected with a guide post, and the guide post is fixedly connected to the bottom of the second gear. The bottom of the support base is fixedly connected with a limit buckle at the position between the second gear and the guide frame. The inner wall of the limit buckle is slidably connected with a limit block, and the limit block is fixedly connected to the drive plate.

[0015] By employing the above technical solution, this utility model provides an automatic feeding mechanism for a grinding mill. It possesses at least the following beneficial effects:

[0016] I. This utility model, through the setting of an adjustment mechanism, after the material is put into the feeding hopper, the pusher plate is driven by the motor to rotate, thereby causing the material in the circular trough to rotate and tumble until it moves to the discharge port of the circular trough and is discharged. During the discharge process, the size of the discharged material can be adjusted by adjusting the height of the baffle through the electric telescopic rod, so that some larger particles will be blocked by the baffle. This ensures that the particle size of the material transported by the conveyor belt to the feed port for processing is consistent with the size of the grinding mill body, thus avoiding the problem that large particles may not be fully ground due to large differences in material particle size, resulting in coarse particles in the ground powder and affecting product quality.

[0017] II. In this utility model, while the motor drives the pusher plate to rotate, it also drives the first gear to rotate. The second gear, which meshes with the first gear, drives the guide column to rotate. The limit buckle and the limit block are connected to limit the rotation, so that the drive plate moves left and right under the push of the guide column. This causes the magnetic suction plate to drive the sliding frame to slide left and right in the guide frame. After the material discharged from the discharge port enters the guide frame, the sliding frame slides left and right, so that the material discharged from the distribution port falls evenly on the conveyor belt. This ensures that the material is evenly distributed on the conveyor belt and falls evenly in the processing area inside the grinding mill body, avoiding the problem of uneven force on the grinding roller caused by the material accumulating in one place.

Detailed Implementation

[0024] 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.

[0025] Example 1

[0026] An automatic feeding mechanism for a grinding mill, such as Figure 1 - Figure 3 As shown, the mill includes a grinding mill body 1. A feed inlet 2 is fixedly connected to the top of the grinding mill body 1. A support frame 3 is fixedly connected to the back of the grinding mill body 1, and the support frame 3 extends into the inside of the feed inlet 2. A conveyor belt 4 is connected to the support frame 3. An adjustment mechanism 5 is set above the conveyor belt 4 on the support frame 3. The adjustment mechanism 5 includes a support base 51, which is fixedly connected to the top of the support frame 3 at the bottom. A circular groove 53 is opened on the top of the support base 51, and a discharge port is opened on the circular groove 53 corresponding to the position of the conveyor belt 4. A feeding bin 52 is fixedly connected to the top of the support base 51 above the circular groove 53. A support plate 54 is fixedly connected to the top of the feeding bin 52. An electric telescopic rod 55 is fixedly connected to the bottom of the support plate 54. A baffle 56 is fixedly connected to the bottom of the electric telescopic rod 55. A pusher plate 59 is rotatably connected to the bottom of the inner wall of the circular groove 53. A motor 58 is fixedly connected to the bottom of the support base 51 through a support frame 57 to drive the pusher plate 59 to rotate.

[0027] In this embodiment, by setting the adjustment mechanism 5, after the material is put into the feeding bin 52, the pusher plate 59 is rotated by the motor 58, so that the material in the circular groove 53 rotates and turns until it moves to the discharge port of the circular groove 53 and is discharged. During the discharge process, the size of the discharged material can be adjusted by adjusting the height of the baffle 56 by the electric telescopic rod 55, so that some larger particles will be blocked by the baffle 56, so that the particle size of the material transported by the conveyor belt 4 to the feed port 2 for processing is consistent with the size of the grinding mill body 1, so as to avoid large particles that may not be fully ground during grinding due to large differences in material particle size.

[0028] Example 2

[0029] like Figure 2 , Figure 3 , Figure 4As shown, a distribution mechanism 6 is installed at the discharge port of the circular trough 53. The distribution mechanism 6 includes a guide frame 61, which is fixedly connected to the support base 51 below the discharge port. A sliding frame 62 is slidably connected to the inner wall of the guide frame 61 via a limiting rod 65. A distribution port 63 is opened on the sliding frame 62 near the conveyor belt 4. Elastic strips 64 are fixedly connected to both sides of the sliding frame 62, and each elastic strip 64 is fixedly connected to the corresponding side of the inner wall of the guide frame 61. A magnetic suction plate 66 is connected to the bottom of the sliding frame 62. A drive plate 69 is slidably connected to the bottom of the guide frame 61 at the position corresponding to the magnetic suction plate 66, and the drive plate 69 is magnetically connected to the magnetic suction plate 66. For sexual attraction, the output shaft of motor 58 is fixedly fitted with a first gear 67, the outer wall of the first gear 67 is meshed with a second gear 68, and the second gear 68 is rotatably connected to the support base 51. The drive plate 69 is provided with a sliding groove 691 below the second gear 68. The inner wall of the sliding groove 691 is slidably connected with a guide post 692, and the guide post 692 is fixedly connected to the bottom of the second gear 68. The bottom of the support base 51 is fixedly connected with a limit buckle 694 at the position between the second gear 68 and the guide frame 61. The inner wall of the limit buckle 694 is slidably connected with a limit block 693, and the limit block 693 is fixedly connected to the drive plate 69.

[0030] In this embodiment, while the motor 58 drives the pusher plate 59 to rotate, it also drives the first gear 67 to rotate. The second gear 68, which meshes with the first gear 67, drives the guide column 692 to rotate. The limit buckle 694 and the limit block 693 are connected to limit the rotation, so that the drive plate 69 moves left and right under the push of the guide column 692. The magnetic suction plate 66 drives the sliding frame 62 to slide left and right in the guide frame 61. After the material discharged from the discharge port enters the guide frame 61, the sliding frame 62 slides left and right, so that the material discharged from the distribution port 63 falls evenly on the conveyor belt 4. This makes the material on the conveyor belt 4 evenly distributed and falls evenly in the processing area inside the mill body 1, avoiding the problem of uneven force on the grinding roller caused by the accumulation of material in one place.

[0031] In operation, the automatic feeding mechanism for a grinding mill of this utility model, through the setting of the adjustment mechanism 5, allows the material to be placed into the feeding bin 52. The motor 58 drives the pusher plate 59 to rotate, causing the material in the circular trough 53 to rotate and tumble until it reaches the discharge port of the circular trough 53 for discharge. During the discharge process, the size of the discharged material can be adjusted by using the electric telescopic rod 55 to adjust the height of the baffle 56. This ensures that larger particles are blocked by the baffle 56, guaranteeing that the particle size of the material transported by the conveyor belt 4 to the feeding port 2 for processing matches the size required for grinding by the grinding mill body 1. This prevents large particles from being insufficiently ground during grinding due to large particle size differences. As the material plate 59 rotates, it also drives the first gear 67 to rotate. The second gear 68, which meshes with the first gear 67, drives the guide column 692 to rotate. The limit buckle 694 and the limit block 693 are connected to limit the rotation, so that the drive plate 69 moves left and right under the push of the guide column 692. This causes the magnetic suction plate 66 to drive the sliding frame 62 to slide left and right in the guide frame 61. After the material discharged from the discharge port enters the guide frame 61, the sliding frame 62 slides left and right, so that the material discharged from the distribution port 63 falls evenly on the conveyor belt 4. This ensures that the material on the conveyor belt 4 is evenly distributed and falls evenly in the processing area inside the mill body 1, avoiding the problem of uneven force on the grinding roller caused by the accumulation of material in one place.
