Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to an improved stable transmission ball mill. Background Technology

[0002] A ball mill is a key piece of equipment that uses steel balls inside a rotating cylinder to impact and grind materials, thereby refining them. Currently, ball mills generally use gear transmission, but this method suffers from problems such as high noise and easy wear of gears. Timely addition of gear lubricating oil is required to ensure the normal operation of the equipment. Therefore, an improved stable transmission ball mill is needed, which is suitable for dry or wet ball milling systems that operate continuously for a long time and have high requirements for transmission stability.

[0003] For example, Chinese patent application number 2022206070845 discloses a belt-driven ball mill, which includes a cylinder, an inner cylinder, a first block, a first mounting component, a second block, a second mounting component, a belt, and a drive device. The inner cylinder is provided inside the cylinder, and the first block is mounted on the inner cylinder through the first mounting component. By optimizing the setting of the belt and drive device, the drive coordination effect is good. However, the belt is prone to tension attenuation and slippage, resulting in a decrease in transmission efficiency and an increase in energy consumption.

[0004] Based on the above solutions, existing ball mills use conveyor belts for multi-stage transmission. However, under high load and long cycle operation conditions, the plastic elongation of the belt will lead to tension attenuation and slippage, and the belt is prone to deviation. Dust easily adheres to the belt surface, which can easily cause slippage between the belt and the pulley and is difficult to clean. During the transmission process, the uneven tension of multiple parallel belts will cause some belts to wear severely or even break, resulting in reduced transmission efficiency and increased energy consumption. In severe cases, it is necessary to stop the machine for maintenance, which will affect continuous production. Utility Model Content

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] An embodiment of an improved stable transmission ball mill provided by this utility model:

[0032] like Figures 1 to 4 As shown, it includes a ball mill assembly 1, a transmission assembly 2, and an adjustment assembly 3. The transmission assembly 2 is located on one side of the ball mill assembly 1, and the adjustment assembly 3 is located on the transmission assembly 2.

[0033] like Figure 2 As shown, the ball mill assembly 1 includes a ball mill body 101. A fixed pulley 104 is provided on the surface of the ball mill body 101. Bearing seats 102 are provided at both ends of the ball mill body 101. The bearing seats 102 are connected to the ball mill body 101 through the main shaft. A fixed bracket 103 is provided below the bearing seats 102.

[0034] The transmission assembly 2 includes a main transmission wheel 201 and a driven transmission wheel 202. A first transmission belt 203 is provided between the main transmission wheel 201 and the driven transmission wheel 202. A pulley 204 is provided on one side of the driven transmission wheel 202. A second transmission belt 206 is provided between the pulley 204 and the fixed pulley 104. The driven transmission wheel 202 is connected to the pulley 204 through a rotating shaft, and a support seat 205 is provided at both ends of the rotating shaft. A drive motor 207 is provided on one side of the main transmission wheel 201. One end of the output shaft of the drive motor 207 is connected to the main transmission wheel 201. A base 208 is provided below the drive motor 207.

[0035] When in use, start the drive motor 207. The drive motor 207 drives the main drive wheel 201 to rotate together. Under the action of the drive motor 207, the power is transmitted sequentially through the main drive wheel 201, the first drive belt 203, the secondary drive wheel 202, the pulley 204, and the second drive belt 206 to the fixed pulley 104, thereby driving the ball mill body 101 to rotate.

[0036] like Figure 3 , Figure 4 As shown, the adjusting assembly 3 includes a support roller 301, which is located below the second transmission belt 206. A limiting roller 305 is located above the support roller 301. A limiting bracket 306 is located on the limiting roller 305. An elastic spring 308 is located at the top of the limiting bracket 306. A positioning plate 309 is located at the end of the elastic spring 308 away from the limiting bracket 306. A limiting rod 307 is located inside the elastic spring 308.

[0037] The limiting rod 307 extends through and to the outside of the positioning plate 309. One end of the limiting rod 307 is fixedly connected to the limiting bracket 306. The surface of the positioning plate 309 is provided with a limiting hole that matches the limiting rod 307.

[0038] In use, the support roller 301 and the limiting roller 305 cooperate to limit the second transmission belt 206, which is located between the support roller 301 and the limiting roller 305. The limiting roller 305 is elastically limited by the structure of elastic spring 308 and limiting rod 307.

[0039] like Figure 3 As shown, a support frame 302 is provided on the support roller 301, and a cylinder 303 is provided below the support frame 302. A positioning frame 304 is provided at the end of the cylinder 303 away from the support frame 302. The positioning frame 304 is fixedly connected to the positioning plate 309 by bolts.

[0040] In use, the position and height of the support roller 301 in the vertical direction are controlled by the cylinder 303, thereby adjusting the tension of the second transmission belt 206.

[0041] like Figure 2 As shown, there are multiple second transmission belts 206 and multiple limiting rollers 305, and the second transmission belts 206 and the limiting rollers 305 correspond one-to-one. The surface of the limiting rollers 305 is provided with a cleaning sleeve 310.

[0042] Both the pulley 204 and the fixed pulley 104 have multiple grooves on their surfaces, and the grooves are spaced apart. The second transmission belt 206 is adapted to the grooves.

[0043] It is worth noting that the cleaning sleeve 310 can be made of felt to clean dust and impurities from the surface of the second drive belt 206 during operation.

[0044] Existing ball mills use conveyor belts for multi-stage transmission. However, under high load and long-cycle operation conditions, belt plastic elongation leads to tension attenuation and slippage, causing belt misalignment. Dust easily adheres to the belt surface, causing slippage between the belt and pulleys, and is difficult to clean. During transmission, uneven tension among multiple parallel belts causes severe wear or even breakage of some belts, resulting in decreased transmission efficiency, increased energy consumption, and in severe cases, requiring shutdown for maintenance, affecting continuous production. To solve this problem, the following measures are taken:

[0045] In actual use, the drive motor 207 is first started, which drives the main drive wheel 201 to rotate. Under the action of the drive motor 207, the power is transmitted sequentially through the main drive wheel 201, the first drive belt 203, the driven wheel 202, the pulley 204, and the second drive belt 206 to the fixed pulley 104, thereby driving the ball mill body 101 to rotate. During this process, the second drive belt 206 will vibrate. To prevent the second drive belt 206 from shifting position, the second drive belt 206 is elastically limited by the cooperation of the support roller 301, the limiting roller 305, the elastic spring 308, and the limiting rod 307. The support roller 301 and the limiting roller 305 elastically clamp the second transmission belt 206, limiting the lateral displacement of the second transmission belt 206 and reducing wear. Specifically, when the second transmission belt 206 vibrates, under the action of the elastic spring 308, the limiting roller 305 moves up and down in the vertical direction along with the second transmission belt 206. At this time, the limiting bracket 306 and the limiting rod 307 move together with the limiting roller 305, and the limiting rod 307 moves in the limiting hole on the surface of the positioning plate 309, thereby preventing the position of the second transmission belt 206 from shifting, and at the same time buffering the vibration of the second transmission belt 206 to ensure the stable operation of the second transmission belt 206.

[0046] It is worth noting that during the above process, the cleaning sleeve 310 on the surface of the limiting roller 305 automatically cleans the dust adhering to the surface of the second transmission belt 206, avoiding excessive dust adhering to the surface of the second transmission belt 206, reducing the coefficient of friction, and increasing the risk of slippage.

[0047] By setting multiple second transmission belts 206 and multiple sets of limiting rollers 305, with the number of second transmission belts 206 and limiting rollers 305 corresponding one-to-one, the transmission capacity is improved and the load is distributed, thereby reducing the load on a single belt and extending its service life.

[0048] In addition, by setting a displacement sensor on the limit rod 307, the deformation of the elastic spring 308 can be detected by the displacement sensor. The sag of the second transmission belt 206 can be obtained based on the deformation of the elastic spring 308, and then the tension of the second transmission belt 206 can be calculated.

[0049] If the tension of the second transmission belt 206 exceeds the preset value, it indicates that the second transmission belt 206 is in a slack state and the tension is reduced. At this time, the controller controls the cylinder 303 to extend. The cylinder 303 drives the support frame 302 and the support roller 301 to move together towards the limit roller 305. That is, the support roller 301 pushes the second transmission belt 206 upward. Under the action of the support roller 301, the second transmission belt 206 is stretched and the tension increases and returns to the standard range, so that the second transmission belt 206 works normally.

[0050] It is worth noting that by detecting the deformation of the elastic spring 308 through the displacement sensor, the sag of the second transmission belt 206 can be obtained based on the deformation of the elastic spring 308, that is, the tension of each second transmission belt 206 can be known. If the tension of a certain second transmission belt 206 is abnormal, it indicates that the second transmission belt 206 needs to be replaced. At this time, the machine should be stopped and an alarm should be sounded. By monitoring the tension of each second transmission belt 206 in real time, timely adjustments and replacements can be made.

[0051] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
