Description

Technical Field

[0001] This application relates to the technical field of auxiliary equipment for lubricating grease processing, and in particular to a feeding device for a grinding machine. Background Technology

[0002] In the grease processing process, various raw materials are usually added to a mixing tank, and a stirring rod is inserted into the mixing tank to stir until the raw materials are mixed evenly to obtain grease. The obtained grease usually needs to be ground in a grinding mill to ensure that the grease has the required uniformity and texture.

[0003] When adding grease to a grinding mill, greases with low viscosity are usually poured into the mill by tilting the mixing tank with the opening facing downwards, making loading easier. For greases with higher viscosity, because the grease flows more slowly, it is usually necessary to manually add the grease from the mixing tank into the grinding mill to improve work efficiency, thus increasing the labor intensity of the workers. Utility Model Content

[0004] To reduce the labor intensity of workers, this application provides a feeding device for a grinding machine.

[0005] The feeding device for a grinding mill provided in this application adopts the following technical solution:

[0006] A feeding device for a grinding mill includes a frame detachably connected to a mixing tank. The frame is equipped with a lifting assembly that drives the mixing tank to move along the height direction of the frame. A discharge port is opened on the lower side of the mixing tank. A baffle is provided on the bottom wall of the mixing tank to block the discharge port. A discharge pipe corresponding to the discharge port is installed on the lower side of the outside of the mixing tank. An auger is rotatably connected in the discharge pipe.

[0007] By adopting the above technical solution, the mixing tank containing lubricating grease is installed on the frame through a lifting component. The lifting component lifts the mixing tank to the position above the discharge pipe, drives the baffle to open the discharge port and drives the auger to rotate, so that the lubricating grease in the mixing tank flows out under the drive of the auger, reducing the possibility of manual feeding and reducing the labor intensity of the workers.

[0008] Optionally, a insertion groove communicating with the discharge port is provided on one side of the bottom wall of the mixing tank, the baffle can be fully inserted into the insertion groove, and a first hydraulic cylinder for driving the baffle into the insertion groove is installed in the insertion groove.

[0009] By adopting the above technical solution, the telescopic rod of the first hydraulic cylinder extends or shortens, thereby controlling the baffle to block or open the discharge port, which facilitates the preparation of lubricating grease and material feeding. When the baffle opens the discharge port, it is fully inserted into the insertion groove, reducing the adverse effects on material feeding and reducing the labor intensity of the workers.

[0010] Optionally, the first hydraulic cylinder is slidably connected to the bottom wall of the mixing tank along the height direction of the mixing tank. The end of the first hydraulic cylinder away from the baffle passes through the bottom wall of the mixing tank and is fixedly connected to a control block. A first lead screw is threaded through and connected to the outer wall of the mixing tank.

[0011] By adopting the above technical solution, when blocking the discharge port, the first hydraulic cylinder drives the baffle to move to face the discharge port. At this time, the first screw is driven to rotate, so that the first hydraulic cylinder drives the baffle to rise to be level with the upper side of the bottom wall of the mixing tank, reducing the possibility of difficulty in mixing raw materials in the mixing tank.

[0012] Optionally, a toothed ring is fitted around the outside of the auger, and mounting rods for connecting the toothed ring are fixedly connected to both sides of the auger. A gear that meshes with the toothed ring is provided on the outside of the discharge pipe, and a first motor that drives the gear to rotate is installed on the lower side of the outside of the mixing tank.

[0013] By adopting the above technical solution, the first motor drives the gear to rotate the gear ring. At this time, the gear ring drives the auger to rotate through the mounting rod, which facilitates the discharge of lubricating grease from the mixing tank and the feeding of materials, reducing the possibility of manual feeding and reducing the labor intensity of workers.

[0014] Optionally, the lifting assembly includes locking blocks inserted into both sides of the mixing tank. A second hydraulic cylinder is installed at the ends of the locking rods that are far apart from each other. A drive block is provided at the ends of the second hydraulic cylinders that are far apart from each other. A second lead screw is provided on the frame that corresponds to the drive block and drives the drive block to move along the height direction of the frame.

[0015] By adopting the above technical solution, the second hydraulic cylinder drives the locking block to move and insert it into the side wall of the mixing tank. At this time, the second lead screw is driven to rotate, causing the drive block to drive the second hydraulic cylinder, the locking block and the mixing tank to move upward, thereby making it easier to lift the mixing tank to facilitate unloading, further reducing the possibility of manual loading and reducing the labor intensity of the workers.

[0016] Optionally, each of the second hydraulic cylinders is rotatably connected to a corresponding drive block, and a second motor is mounted on one of the drive blocks. The output shaft of the second motor passes through the drive block and is fixedly connected to the end of the second hydraulic cylinder.

[0017] By adopting the above technical solution, when the clamping block lifts the mixing tank, the second motor moves with the mixing tank. After the mixing tank is lifted, the second motor drives the second hydraulic cylinder and the clamping block to rotate the mixing tank to an inclined position. At this time, the discharge pipe is located above the feeding point, thereby shortening the lifting distance of the mixing tank and improving work efficiency.

[0018] Optionally, the upper end of the mixing tank is provided with a cover, and a pressure plate with a diameter equal to the inner diameter of the mixing tank is inserted into and slidably connected to the lower side of the cover. The pressure plate can enter the mixing tank and move along the length of the mixing tank. The cover is provided with a driving component to drive the pressure plate into the mixing tank.

[0019] By adopting the above technical solution, the cover is installed on the mixing tank. When the mixing tank discharges material through the discharge pipe, the drive unit drives the pressure plate to move towards the discharge pipe, which facilitates the grease to be pressed out through the pressure plate while the auger is discharging material, thereby improving the material discharge efficiency.

[0020] Optionally, the cover has an internal cavity, and the lower side of the cover has multiple drive holes communicating with the cavity. When the pressure plate is inserted into the cover, it blocks the drive holes. The drive component includes a vacuum tube installed on the upper side of the cover and communicating with the cavity.

[0021] By adopting the above technical solution, air is introduced into the vacuum tube. At this time, the air passes through the cavity and the drive hole and pushes the pressure plate to move closer to the mixing tank. After the grease is completely squeezed out, the air is extracted through the vacuum tube, which facilitates the reset of the pressure plate and improves the feeding efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The mixing tank containing grease is installed on the frame using a lifting assembly. The mixing tank is then lifted by the lifting assembly until the discharge pipe is above the feeding point. The drive baffle opens the discharge port and drives the auger to rotate, so that the grease in the mixing tank flows out under the drive of the auger, reducing the possibility of manual feeding and reducing the labor intensity of the workers.

[0024] 2. When the clamping block lifts the mixing tank, the second motor moves with the mixing tank. After the mixing tank is lifted, the second motor drives the second hydraulic cylinder and the clamping block to rotate the mixing tank to an inclined position. At this time, the discharge pipe is located above the feeding point, thereby shortening the lifting distance of the mixing tank and improving work efficiency.

[0025] 3. Install the cover on the mixing tank. When the mixing tank discharges material through the discharge pipe, the drive unit drives the pressure plate to move closer to the discharge pipe, so that the grease can be pressed out through the pressure plate at the same time as the auger discharges material, thereby improving the material discharge efficiency.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a feeding device for a grinding mill. (Refer to...) Figure 1 and Figure 2 A feeding device for a grinding mill includes a mixing tank 1 and a frame 2 detachably connected to the mixing tank 1. Rollers 21 are installed at the four corners of the lower end of the frame 2 to facilitate movement. A lifting assembly 3 for driving the mixing tank 1 is provided on the frame 2. A discharge port 11 is opened at the center of the lower end of the mixing tank 1. A vertical discharge pipe 12, communicating with the discharge port 11, is fixedly connected to the lower outside of the mixing tank 1. A vertical auger 13 is rotatably connected to the discharge pipe 12.

[0032] The lower end of the mixing tank 1 is provided with a horizontal baffle 4 that blocks the discharge port 11. A insertion groove 14 is provided on one side of the lower end of the mixing tank 1, which communicates with the discharge port 11 and is lower than the upper side of the bottom wall of the mixing tank 1. The baffle 4 can be completely inserted into the insertion groove 14. A first hydraulic cylinder 41 with a telescopic rod facing the baffle 4 and fixedly connected to the side wall of the baffle 4 is provided in the insertion groove 14. The end of the first hydraulic cylinder 41 away from the baffle 4 passes through the side wall of the mixing tank 1 and is fixedly connected to a control block 42. The first hydraulic cylinder 41 is slidably connected to the mixing tank 1 in the vertical direction, and a first lead screw 43 is rotatably connected to the outer side wall of the mixing tank 1, which passes through the control block 42 and is threadedly connected.

[0033] Reference Figure 2 and Figure 3Both sides of the lower end of the auger 13 are fixedly connected to horizontal mounting rods 131. A gear ring 132, which is inserted into the side wall of the discharge pipe 12 and rotatably connected to the discharge pipe 12, is sleeved and fixedly connected to the outside of the mounting rods 131. The inner diameter of the gear ring 132 is equal to the inner diameter of the discharge pipe 12. A horizontal gear 133 is provided on one side of the discharge pipe. One side of the gear 133 is inserted into the discharge pipe 12 and meshes with the gear ring 132. A first motor 134, which is fixedly connected to the outer wall of the mixing tank 1, is mounted on the upper end of the gear 133.

[0034] The mixing tank 1 is installed on the frame 2 via the lifting assembly 3. The lifting assembly 3 lifts the mixing tank 1 to the position above the discharge pipe 12 at the feeding point. The first lead screw 43 is driven to rotate and the baffle 4 is driven to move downwards to be directly opposite the insertion slot 14 via the control block 42 and the first hydraulic cylinder 41. At this time, the telescopic rod of the first hydraulic cylinder 41 retracts until the baffle 4 is fully inserted into the insertion slot 14, thereby opening the discharge port 11. The first motor 134 drives the gear 133 and the gear ring 132 to rotate and drive the auger 13 to rotate, so that the grease in the mixing tank 1 flows out under the drive of the auger 13, which facilitates feeding.

[0035] When the discharge port 11 needs to be blocked after the material is discharged, the first hydraulic cylinder 41 drives the baffle 4 to move to face the discharge port 11. At this time, the first lead screw 43 is driven to rotate, so that the first hydraulic cylinder 41 drives the baffle 4 to rise to be level with the upper side of the bottom wall of the mixing tank 1, reducing the possibility of difficulty in mixing the raw materials in the mixing tank 1.

[0036] Reference Figure 1 and Figure 2 The lifting assembly 3 includes two symmetrically arranged locking blocks 31 on both sides of the mixing tank 1, with one end close to the other inserted into the side wall of the mixing tank 1. The vertical cross-section of the locking block 31 is square, and the ends of the locking blocks 31 that are far apart from each other are provided with horizontal second hydraulic cylinders 32. The telescopic rods of the second hydraulic cylinders 32 are directed toward the corresponding locking block 31 and are fixedly connected to the locking block 31.

[0037] Each of the second hydraulic cylinders 32 has a drive block 33 rotatably connected to one of its opposite ends. Each drive block 33 passes through the frame 2 and slides vertically with it. A second motor 34 is fixedly connected to the side of one drive block 33 furthest from its corresponding second hydraulic cylinder 32. The output shaft of the second motor 34 passes through the drive block 33 and is fixedly connected to the second hydraulic cylinder 32. Vertical second lead screws 35, corresponding one-to-one with the drive blocks 33 and threadedly connected to them, are rotatably connected to both sides of the frame 2. A third motor 36, which drives the second lead screws 35, is mounted on the upper end of the frame 2.

[0038] The second hydraulic cylinder 32 drives the locking block 31 to move and insert it into the side wall of the mixing tank 1. At this time, the third motor 36 drives the second lead screw 35 to rotate, causing the drive block 33 to drive the second hydraulic cylinder 32, the locking block 31 and the mixing tank 1 to move upward, thereby lifting the mixing tank 1. At this time, the second motor 34 drives the second hydraulic cylinder 32 and the locking block 31 to rotate the mixing tank 1 to tilt. At this time, the discharge pipe 12 is located above the feeding point, thereby shortening the rising distance of the mixing tank 1 and improving working efficiency.

[0039] Reference Figure 1 and Figure 2 The mixing tank 1 has a cover 5 on its upper side that covers its own opening. The cover 5 is detachably connected to the mixing tank 1 by a mounting pin (not shown in the figure). A pressure plate 51 with a diameter equal to the inner diameter of the mixing tank 1 is inserted into and slidably connected to the lower side of the cover 5. A cavity 52 is opened inside the cover 5, and multiple evenly distributed drive holes 53 communicating with the cavity 52 are provided on the lower side of the cover 5. When the pressure plate 51 is fully inserted into the cover 5, the lower side of the pressure plate 51 is flush with the lower side of the cover 5, and the drive holes 53 are completely blocked. The cover 5 is provided with a drive component that drives the pressure plate 51 into the mixing tank 1 and slides it. In this embodiment, the drive component is set as a vertical vacuum tube 54 installed on the upper side of the cover 5 and communicating with the cavity 52.

[0040] The cover 5 is installed on the mixing tank 1. When the mixing tank 1 discharges material through the discharge pipe 12, air is introduced into the vacuum pipe 54. At this time, the air passes through the cavity 52 and the drive hole 53 and pushes the pressure plate 51 to move closer to the mixing tank 1, so that the grease can be squeezed out through the pressure plate 51 at the same time as the auger 13 discharges material. After the grease is completely squeezed out, the air is extracted through the vacuum pipe 54, which facilitates the reset of the pressure plate 51.

[0041] The implementation principle of a feeding device for a grinding mill according to an embodiment of this application is as follows: the mixing tank 1 is installed on the frame 2 and raised until the discharge pipe 12 is located above the feeding point. The drive baffle 4 is moved to fully enter the insertion slot 14, thereby opening the discharge port 11 and driving the auger 13 to rotate, so that the grease in the mixing tank 1 flows out under the drive of the auger 13, which facilitates feeding.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
