Description

Technical Field

[0001] This invention relates to the field of ball mill technology, and more specifically to an automatic ball-feeding ball mill device. Background Technology

[0002] Ball mills are widely used grinding equipment in mining, building materials, chemical and other fields. Their core working principle involves the machine body driving internal grinding balls to rotate at high speed, utilizing the collision and friction between the grinding balls and the material to be ground to achieve material refinement. However, with the increasing automation of industrial production, traditional ball mills have gradually revealed many technical shortcomings in practical applications, making it difficult to meet the demands of efficient, continuous, and automated production.

[0003] Firstly, the replenishment of grinding balls in existing ball mills largely relies on manual operation. Since grinding balls gradually wear down during long-term grinding, they need to be replenished periodically to maintain grinding efficiency. However, traditional ball mills require operators to manually open the top cover of the machine to add grinding balls after the machine is stopped. This not only interrupts the production process and reduces overall operational efficiency but also increases the labor intensity of the operators. Some ball mills that attempt to achieve automatic ball feeding often use independent ball feeding drive mechanisms (such as cylinders or motors) to control the feeding. This not only increases the manufacturing cost and energy consumption of the equipment but also presents problems with the coordination between the ball feeding action and the discharge and grinding processes, easily leading to incorrect or untimely ball feeding.

[0004] Secondly, existing ball mills suffer from poor adaptability between feeding and grinding conditions. Traditional ball mills often employ fixed feeding mechanisms, where the conveying power and grinding power are independent. During feeding, relative motion interference easily occurs between the feeding mechanism and the rotating machine body, leading to material conveying jams and uneven feeding. Conversely, if the feeding mechanism rotates synchronously with the machine body, it cannot provide a stable fixed reference for subsequent material pushing and discharging actions, making smooth switching between feeding, grinding, and discharging conditions difficult. Some equipment uses complex mechanical clutch structures to achieve condition switching, but this suffers from slow switching response, severe mechanical wear, and susceptibility to jamming failures, affecting the equipment's operational reliability.

[0005] Secondly, the existing material feeding and discharge control structures of ball mills are cumbersome and lack coordination. Traditional ball mills often use independent drive components (such as hydraulic rods or electric push rods) to control the material feeding and discharge baffle opening and closing. This not only increases the complexity of the internal structure of the equipment and raises assembly and maintenance costs, but also results in problems such as lag in action transmission and poor coordination. For example, it is difficult to precisely match the material feeding stroke with the opening range of the discharge baffle, which can easily lead to material residue inside the machine or material splashing during discharge. At the same time, the movement guidance accuracy of the feeding mechanism is insufficient, which can easily cause deviation and jamming, further affecting the discharge efficiency and stability. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic ball mill device with ball feeding, which solves the problems mentioned in the background art.

[0007] The solution of the present invention to the above-mentioned technical problems is as follows:

[0008] This invention provides an automatic ball mill device, comprising: a base, a machine body, a drive mechanism, a feeding mechanism, an automatic ball-adding mechanism, an inner liner, a pusher plate linkage mechanism, and a locking switching mechanism; the machine body is rotatably supported and mounted on the base, the drive mechanism is mounted on the base and is connected to the machine body for driving the machine body to rotate; the inner liner is located inside the machine body and rotates in linkage with the machine body, the feeding mechanism is rotatably supported on the end of the base away from the drive mechanism and extends through the inner liner into the machine body, used to convey grinding parts into the machine body; the automatic ball-adding mechanism is located at the top of the machine body, used to store grinding balls and realize automatic feeding of grinding balls; the pusher plate linkage mechanism is located inside the inner liner and is linked with the automatic ball-adding mechanism and the discharge baffle of the machine body respectively, realizing coordinated control of automatic feeding of grinding balls and opening and closing of the discharge port; the locking switching mechanism is located between the machine body and the feeding mechanism, used to switch the follow-up rotation state and the locked state of the feeding mechanism, and cooperates with the pusher plate linkage mechanism to complete the material pushing and automatic ball-adding actions.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the drive mechanism includes a motor and a reducer. The reducer is mounted on the base and located at one end of the machine body. The motor is mounted on one side of the reducer. The reducer is connected to the motor via a transmission rod. The machine body has rotating shafts at both ends. The rotating shafts are mounted on the first bearing seats at both ends of the base via first bushings. The machine body is connected to the reducer via the rotating shaft at one end.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] By coordinating the motor and reducer, the power can be reduced in speed and increased in torque, precisely matching the low-speed, high-torque rotation conditions required by the ball mill body. This ensures that the inner liner drives the grinding balls to fully collide and grind the grinding parts, improving grinding efficiency and quality. Simultaneously, the reducer effectively reduces the motor load and extends its service life. The rotating shaft is mounted on the first bearing seat via a first bushing, converting the rotational friction of the shaft into rolling friction, significantly reducing frictional resistance and power loss, making the machine body rotate more smoothly and stably. The first bushing also acts as a radial limiter for the rotating shaft, preventing deviation during rotation, ensuring the transmission accuracy between the machine body and various linkage components (such as the inner liner and locking switching mechanism), reducing component wear caused by transmission deviation, and improving the overall operational reliability of the device.

[0013] Furthermore, the machine body is provided with fixing rods on both sides, and a clamp is installed on the base accordingly. The machine body is locked and fixed to the base by the cooperation of the fixing rods and the clamp. The bottom of the end of the machine body away from the automatic ball feeding mechanism is provided with a discharge port. The discharge baffle is slidably installed at the discharge port to control the opening and closing of the discharge port.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The combination of the fixing rod and the clamp ensures a stable lock on the machine body to the base, effectively suppressing vibration and displacement during machine rotation, reducing operating noise, and preventing vibration from affecting transmission and connection components, thus improving the overall operational stability of the device. This fixing method is simple in structure, easy to assemble and disassemble, and facilitates later inspection and maintenance of internal components. The discharge port is located at the bottom of the machine body, conforming to the law of material gravity, allowing the ground material to be discharged quickly and smoothly, reducing material residue in the machine body. The discharge baffle adopts a sliding installation method, with a compact structure and flexible operation, which can precisely control the opening and closing state of the discharge port. Closing it during grinding ensures the airtightness of the machine body, preventing grinding balls or grinding parts from splashing, while opening it during discharge allows for rapid material unloading, improving work efficiency.

[0016] Furthermore, the automatic ball feeding mechanism includes a feeding hopper and a discharging assembly. The feeding hopper is located on one side of the top of the machine body for storing grinding balls, and the discharging assembly is installed inside the feeding hopper. The discharging assembly includes a guide plate, a flap, a second connecting plate, a pin, a ratchet mechanism, and a drive plate. The flap is rotatably mounted on the lower end of the guide plate via a torsion spring shaft. The lower part of the flap is connected to the second connecting plate. The end of the second connecting plate opposite to the flap is rotatably connected to the drive plate via a pin and a ratchet mechanism. The ratchet mechanism enables unidirectional transmission. When the drive plate pushes forward, it drives the second connecting plate to deflect via the ratchet mechanism, thereby driving the flap to deflect and open for discharging. When the drive plate pushes in the reverse direction, only the drive plate deflects and folds, while the flap remains closed.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The feeding hopper allows for centralized storage of grinding balls, eliminating the need for frequent manual replenishment and improving operational continuity. The guide plate directs the grinding balls precisely to the flap, preventing accumulation and blockage within the hopper. A torsion spring provides automatic reset force to the flap, ensuring rapid closure after grinding ball feeding and preventing continuous leakage. The unidirectional transmission characteristic of the ratchet mechanism is key to precise ball feeding control. It strictly distinguishes the direction of the drive plate's movement, triggering the flap to open for feeding only when pushed forward (i.e., when the second push plate resets to replenish grinding balls). When pushed backward (i.e., when the second push plate pushes outward), the drive plate simply avoids the movement, keeping the flap closed. This effectively prevents accidental feeding of grinding balls during discharge, achieving precise isolation between feeding and discharge actions and improving the reliability of feeding control. The entire feeding assembly is compact, requiring no separate drive source; automatic control is achieved through the movement of the second push plate, reducing equipment manufacturing costs and energy consumption.

[0019] Furthermore, the inner liner includes an inner liner, a liner plate, a first end cap, a second end cap, and a guide rod; the inner liner is disposed within the machine body, and the liner plate is installed on the inner wall of the inner liner; the first end cap and the second end cap are respectively installed at both ends of the inner liner, and the rotating shafts at both ends of the machine body are respectively fixed on the first end cap and the second end cap, and the inner liner is driven to rotate within the machine body by the rotating shafts; the guide rod is connected between the first end cap and the second end cap and is used to limit and guide the push plate linkage mechanism.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The first and second end caps seal the inner liner, preventing material or grinding balls from leaking from either end during grinding. They also securely connect the inner liner to the machine's rotating shaft, ensuring precise transmission of rotational power from the machine to the inner liner, achieving synchronous rotation and guaranteeing stable grinding conditions. The liner on the inner wall enhances the collision and friction between the grinding balls and the grinding media, improving grinding efficiency. Simultaneously, the liner directly withstands the impact and wear of the grinding balls, preventing damage to the inner liner and extending its service life. Furthermore, the liner is easy to disassemble and replace, reducing maintenance costs. The guide rod provides precise limiting and guidance for the first and second push plates of the push plate linkage mechanism, ensuring that the push plates can only move along the inner liner's axial direction, preventing deviation or jamming during movement, and ensuring the linkage accuracy between the push plates, the discharge baffle, and the drive plate, thereby improving the stability of the discharge and ball-addition actions.

[0022] Furthermore, the pusher linkage mechanism includes a first pusher plate, a second pusher plate, a spring, a first connecting plate, a second bushing, a connecting rod, and a steel ring; both the first and second pusher plates are sleeved on the feeding mechanism and are limited and installed between the first and second end covers by guide rods; the first pusher plate is elastically connected to the first end cover by the spring to achieve elastic reset; the first pusher plate is connected and fixed to the discharge baffle by the first connecting plate to achieve linkage between the first pusher plate and the discharge baffle; the second pusher plate is rotatably mounted on the second bushing, and a steel ring is connected to one side surface of the second bushing by a connecting rod, the steel ring being used to contact the first pusher plate and push it to move when the second pusher plate moves.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] Both the first and second push plates are fitted onto the feeding mechanism and limited by guide rods, ensuring the coaxiality and stability of the push plate movement and preventing push plate offset from affecting motion transmission. The spring design enables automatic elastic reset of the first push plate, eliminating the need for an additional reset drive assembly and simplifying the structure. After discharge, the first push plate, under the action of the spring, can automatically close the discharge port with the discharge baffle, preparing for the next round of grinding operations and improving the level of automation. The first connecting plate achieves rigid linkage between the first push plate and the discharge baffle, ensuring that the movement of the first push plate is accurately transmitted to the discharge baffle, achieving synchronous opening and closing of the discharge baffle and avoiding problems of delayed or incomplete opening and closing due to transmission gaps. The second push plate is rotatably mounted via a second bushing, adapting to the combined motion requirements of inner liner rotation and its own axial movement, reducing motion interference. The steel ring increases the contact area between the second and first push plates, making the pushing force of the second push plate on the first push plate more uniform, preventing excessive local stress that could cause component deformation, while also reducing contact wear and extending the service life of the linkage mechanism.

[0025] Furthermore, the feeding mechanism includes a guide rod and an auger. The auger is located inside the guide rod, which has a feed inlet located below the unloading assembly. The guide rod has a threaded groove. The feeding mechanism is supported and installed on the base by a second bearing seat. The grinding parts are conveyed to the feed inlet by the auger and then enter the machine body through the feed inlet.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The guide rod provides a mounting platform and protection for the auger, while also guiding the grinding parts to prevent them from scattering during transport. The auger's spiral conveying structure enables continuous and uniform feeding of the grinding parts, allowing them to fully mix and contact with the grinding balls inside the machine, improving grinding uniformity and quality stability. Compared to traditional gravity feeding methods, this effectively avoids feeding blockage problems. The feed inlet is located below the unloading assembly, allowing the grinding parts and grinding balls to enter the machine in the same area, further improving mixing efficiency. The threaded groove on the guide rod provides a transmission basis for the axial movement of the subsequent second pusher plate, achieving functional synergy between the feeding mechanism and the pusher plate linkage mechanism. The second bearing seat provides stable support for the feeding mechanism, ensuring its stability in both rotating and locked states, preventing feeding accuracy or transmission reliability from being affected by the feeding mechanism's wobbling.

[0028] Furthermore, the inner surface of the second bushing is provided with a protrusion. When the locking switching mechanism locks the feeding mechanism, the second push plate moves along the guide rod through the engagement of the protrusion with the threaded groove on the guide rod as the machine body drives the inner liner to rotate.

[0029] The beneficial effects of adopting the above-mentioned further solutions are:

[0030] The engagement of the protrusion and the threaded groove forms a helical transmission mechanism. This ingenious design transforms the rotational motion of the inner liner driven by the machine body into the axial linear motion of the second pusher plate. It eliminates the need for a separate power source to drive the second pusher plate, fully utilizing existing power sources, simplifying the equipment structure, and reducing energy consumption and manufacturing costs. The helical transmission features smooth transmission, high thrust, and high transmission precision, ensuring the smooth and accurate movement of the second pusher plate along the guide rod. This, in turn, guarantees the accuracy of subsequent actions such as material feeding, opening of the discharge baffle, and replenishment of grinding balls. Furthermore, this transmission method has a compact structure, occupies little space, and can be well adapted to the limited installation space inside the machine body, avoiding movement interference with other components and improving the overall rationality and compactness of the device.

[0031] Furthermore, the locking switching mechanism includes an electromagnet, a first gear disc, a second gear disc, a brake pad, and a keyway; the first gear disc is mounted on a rotating shaft at the end of the machine body facing the second bearing seat, and the electromagnet is mounted on the back of the first gear disc; the brake pad is mounted on the side surface of the second bearing seat facing the machine body; the keyway is opened on the end surface of the feeding mechanism located on the outside of the machine body, and the second gear disc is slidably mounted on the feeding mechanism through the keyway, and a strong magnet is integrated inside the second gear disc; by controlling the magnetic poles of the electromagnet, the second gear disc is driven to move towards the first gear disc or the brake pad, thereby realizing the meshing transmission between the second gear disc and the first gear disc or the contact locking with the brake pad.

[0032] The beneficial effects of adopting the above-mentioned further solutions are:

[0033] Employing an electromagnet magnetic drive, the second gear disc achieves rapid and precise switching. Compared to traditional mechanical drive switching structures, it offers faster response, easier operation, and eliminates mechanical contact wear, effectively reducing the failure rate and extending the service life of the switching mechanism. The keyway design provides circumferential limiting for the second gear disc and the feeding mechanism, ensuring the second gear disc can drive the feeding mechanism to rotate synchronously while allowing it to slide axially along the feeding mechanism, meeting switching requirements. The meshing transmission between the first and second gear discs ensures synchronous rotation of the feeding mechanism and the machine body, guaranteeing smooth feeding; the contact locking between the brake pads and the second gear disc quickly fixes the feeding mechanism, providing a stable transmission foundation for the axial movement of the pusher plate. The entire switching mechanism can switch between two operating conditions via electromagnetic control, requiring no manual intervention, thus improving the automation level of the equipment. The switching process is smooth and does not impact other transmission components, ensuring the stability of the device's operation.

[0034] Furthermore, when the locking switching mechanism locks the feeding mechanism and the drive mechanism drives the machine body to rotate forward, the second push plate moves along the guide rod toward the first push plate, pushes the drive plate in the opposite direction to fold and make room, and at the same time pushes the first push plate to move. Through the first connecting plate, the discharge baffle is moved away from the discharge port to realize the discharge. When the drive mechanism drives the machine body to rotate in reverse, the second push plate resets along the guide rod. When it moves to the unloading component, it pushes the drive plate in the forward direction to make the flip plate rotate in reverse and open, realizing the automatic unloading of grinding balls.

[0035] The beneficial effects of adopting the above-mentioned further solutions are:

[0036] By employing a simple forward and reverse rotation control method, the two key actions of material discharge and grinding ball replenishment can be automatically switched and coordinated, eliminating the need for a complex control system, simplifying the operation process, and lowering the operational threshold. When the machine rotates forward, the second pusher plate simultaneously completes two actions: avoiding the grinding ball feeding mechanism and pushing the material discharge, ensuring that the material discharge process is not interfered with by the grinding ball feeding mechanism and achieving smooth discharge. When the machine rotates in reverse, the second pusher plate's reset process simultaneously triggers automatic grinding ball feeding, allowing grinding ball replenishment to be completed quickly after material discharge, improving operational continuity. The entire process requires no manual intervention, completely solving the problem of traditional ball mills requiring shutdown for manual grinding ball replenishment, significantly improving operational efficiency and reducing the labor intensity of operators. At the same time, the actions are closely linked and logically clear, avoiding action conflicts or omissions, and improving the reliability and automation level of equipment operation.

[0037] Therefore, the automatic ball-adding ball mill device provided by the present invention has the following beneficial effects:

[0038] 1. Achieving coordinated automatic ball replenishment and discharge significantly improves operational continuity and automation. Through the ratchet-driven unidirectional transmission design of the pusher plate linkage mechanism and the automatic ball-adding mechanism, the machine's forward and reverse rotation drives the second pusher plate to move bidirectionally along the guide rod, simultaneously achieving precise coordination of discharge pushing, discharge baffle opening, ball replenishment, and flap opening. Specifically, when the machine rotates forward, the second pusher plate pushes the first pusher plate to open the discharge baffle, while simultaneously pushing the drive plate in the reverse direction, which folds and yields due to the ratchet's unidirectional transmission characteristic, without interfering with discharge. When the machine rotates in reverse, the second pusher plate's reset process pushes the drive plate forward, and the ratchet mechanism drives the flap to open, completing the automatic ball unloading. This design eliminates the need for separate ball-adding and discharge drive components, relying solely on the machine's own rotational power to achieve coordinated control of these two key actions. This not only reduces the number of power sources and equipment manufacturing costs but also avoids operational interruptions caused by manual ball replenishment, significantly improving overall operational efficiency and reducing operator workload.

[0039] 2. The magnetic bidirectional switching design of the locking and switching mechanism ensures adaptability and operational stability for both feeding and grinding operations. By switching the magnetic poles of an electromagnet to drive the sliding of the second toothed disc, the feeding mechanism can be quickly switched between two states: rotating and locked. During the feeding stage, the second toothed disc meshes with the first toothed disc, causing the feeding mechanism to rotate synchronously with the machine, avoiding material jamming caused by the relative rotation of the feeding mechanism and the inner liner during auger conveying of grinding parts, ensuring smooth and stable feeding. During the grinding, discharging, and ball-adding stages, the second toothed disc locks against the brake pads, keeping the feeding mechanism fixed. The rotation of the inner liner is converted into axial movement of the second push plate through the helical transmission of the protrusion and threaded groove, providing stable power for discharging and ball-adding. This switching mechanism, driven by an electromagnet, offers advantages over traditional mechanical switching structures, including faster switching response, easier operation, and no jamming caused by mechanical wear. It can precisely adapt to the working conditions of different stages, improving the reliability and service life of the equipment.

[0040] 3. The integrated design of the pusher plate linkage mechanism simplifies the equipment structure and improves the accuracy and reliability of motion transmission. Material pushing, discharge baffle opening, and ball-adding triggering functions are integrated into the pusher plate linkage mechanism. Through the rigid connection between the first pusher plate and the discharge baffle, the linkage between the second pusher plate and the drive plate, and the elastic return design of the spring, the integrated transmission of multiple actions is achieved. Compared with the existing technology where each action has its own independent drive and transmission components, this design significantly reduces the number of parts, simplifies the internal structure of the equipment, and reduces assembly difficulty and maintenance costs. At the same time, the combination of rigid connection and elastic return design ensures that there is no redundant gap in the motion transmission process, enabling precise matching between the discharge baffle opening range and the material pushing stroke. This avoids problems such as material residue and incomplete discharge caused by motion transmission lag or deviation, thus improving the accuracy of equipment operation.

[0041] 4. The linkage design between the inner liner and the machine body, along with the liner plate, effectively improves grinding efficiency and quality. The inner liner is fixed to the machine body's rotating shaft via end caps at both ends, achieving synchronous rotation with the machine body. The liner plate on the inner wall of the liner enhances the collision and friction between the grinding balls and the grinding parts, improving grinding efficiency. Simultaneously, the guide rod's limiting and guiding effect on the push plate ensures that the push plate always moves along the inner liner's axis, avoiding uneven material grinding caused by push plate misalignment. Furthermore, the auger conveyor design of the feeding mechanism enables continuous and uniform feeding of the grinding parts, allowing for thorough mixing and contact between the grinding parts and grinding balls within the liner, further improving the stability of grinding quality and making it suitable for applications requiring high grinding precision.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figures 1 to 10 As shown, the embodiments provided by the present invention are as follows:

[0058] Example 1

[0059] An automatic ball mill device includes: a base 2, a machine body 4, a drive mechanism, a feeding mechanism 7, an automatic ball-adding mechanism, an inner liner 409, a push plate linkage mechanism, and a locking and switching mechanism; the machine body 4 is rotatably supported and mounted on the base 2, the drive mechanism is mounted on the base 2 and is connected to the machine body 4 for transmission to drive the machine body 4 to rotate; the inner liner 409 is disposed inside the machine body 4 and rotates in linkage with the machine body 4, the feeding mechanism 7 is rotatably supported on the end of the base 2 opposite to the drive mechanism and extends through the inner liner 409 into the interior of the machine body 4, using... The grinding parts are conveyed into the machine body 4; the automatic ball feeding mechanism is located at the top of the machine body 4 and is used to store grinding balls and realize the automatic feeding of grinding balls; the push plate linkage mechanism is located in the inner liner 409 and is linked with the automatic ball feeding mechanism and the discharge baffle 414 of the machine body 4 respectively, realizing the coordinated control of automatic feeding of grinding balls and the opening and closing of the discharge port 421; the locking switching mechanism is located between the machine body 4 and the feeding mechanism 7 and is used to switch the follow-up rotation state and the locking state of the feeding mechanism 7, and cooperate with the push plate linkage mechanism to complete the material pushing and automatic ball feeding action.

[0060] Example 2

[0061] To achieve stable drive of the machine body and precise matching of grinding conditions, and to improve transmission efficiency and equipment reliability, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0062] The drive mechanism includes a motor 1 and a reducer 6. The reducer 6 is mounted on the base 2 and located at one end of the machine body 4. The motor 1 is mounted on one side of the reducer 6. The reducer 6 is connected to the motor 1 via a transmission rod 601. The machine body 4 has rotating shafts 402 at both ends. The rotating shafts 402 are mounted on the first bearing seats 202 at both ends of the base 2 via first bushings 403. The machine body 4 is connected to the reducer 6 via the rotating shaft 402 at one end. Through the cooperation of the motor 1 and the reducer 6, the power can be reduced in speed and increased in torque, which can accurately match the low-speed, high-torque rotation conditions required by the ball mill body 4. This ensures that the inner liner 409 drives the grinding balls to fully collide and grind with the grinding parts, thereby improving grinding efficiency and quality. At the same time, the reducer 6 can effectively reduce the load on the motor 1 and extend the service life of the motor 1. The rotating shaft 402 is mounted on the first bearing seat 202 via the first bushing 403, which can convert the rotational friction of the rotating shaft 402 into rolling friction, greatly reducing frictional resistance, reducing power loss, and making the rotation of the machine body 4 smoother and more stable. The first bushing 403 can also play a radial limiting role for the rotating shaft 402, preventing the rotating shaft 402 from deviating during rotation, ensuring the transmission accuracy of the machine body 4 and each linkage component (such as the inner liner 409 and the locking switching mechanism), reducing component wear caused by transmission deviation, and improving the operational reliability of the entire device.

[0063] Example 3

[0064] To enhance the stability of the machine installation, optimize the discharge structure, ensure smooth operation, and facilitate maintenance, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0065] The machine body 4 has fixing rods 401 on both sides, and clamps 201 are installed on the base 2 accordingly. The machine body 4 is locked and fixed to the base 2 by the cooperation of the fixing rods 401 and the clamps 201. The bottom of the end of the machine body 4 away from the automatic ball feeding mechanism has a discharge port 421. The discharge baffle 414 is slidably installed at the discharge port 421 to control the opening and closing of the discharge port 421. The cooperation of the fixing rods 401 and the clamps 201 realizes the stable locking of the machine body 4 on the base 2, which can effectively suppress the vibration and displacement generated during the rotation of the machine body 4, reduce the operating noise of the equipment, and at the same time avoid the impact of vibration on various transmission components and connecting components, thus improving the overall operating stability of the device. This fixing method has a simple structure and is easy to disassemble and assemble, which facilitates the later inspection and maintenance of the internal components of the machine body 4. The discharge port 421 is located at the bottom of the machine body 4, which conforms to the law of material falling by gravity, allowing the ground material to be discharged quickly and smoothly, reducing the material residue in the machine body 4; the discharge baffle 414 adopts a sliding installation method, which is compact in structure and flexible in operation, and can accurately control the opening and closing state of the discharge port 421. When closed during grinding, it can ensure the airtightness of the machine body 4 and prevent grinding balls or grinding parts from splashing. When opened during discharge, it can achieve rapid material discharge and improve work efficiency.

[0066] Example 4

[0067] To achieve automated and precise feeding of grinding balls, avoid interference between ball feeding and discharging actions, and improve operational continuity, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0068] The automatic ball feeding mechanism includes a feeding hopper 5 and a discharging assembly 501. The feeding hopper 5 is located on one side of the top of the machine body 4 for storing grinding balls. The discharging assembly 501 is installed inside the feeding hopper 5. The discharging assembly 501 includes a guide plate 507, a flap 502, a second connecting plate 503, a pin 504, a ratchet mechanism 505, and a drive plate 506. The flap 502 is rotatably mounted on the lower end of the guide plate 507 via a torsion spring shaft. The lower part of the flap 502 is connected to the second connecting plate 503. The end of the second connecting plate 503 opposite to the flap 502 is connected to the pin 504 and the ratchet mechanism 505. The feed hopper 5 is rotatably connected to the drive plate 506; the ratchet mechanism 505 enables unidirectional transmission. When the drive plate 506 is pushed forward, the ratchet mechanism 505 drives the second connecting plate 503 to deflect, which in turn drives the flap 502 to deflect and open for feeding. When the drive plate 506 is pushed in the reverse direction, only the drive plate 506 deflects and folds, while the flap 502 remains closed. The feed hopper 5 can achieve centralized storage of grinding balls, eliminating the need for frequent manual replenishment and improving the continuity of operation. The guide plate 507 can guide the grinding balls, ensuring that the grinding balls are accurately gathered at the flap 502, preventing the grinding balls from accumulating and clogging in the feed hopper 5. The torsion spring shaft provides automatic reset force for the flap 502, ensuring that the flap 502 closes quickly after the grinding balls are fed, preventing continuous leakage of grinding balls. The unidirectional transmission characteristic of the ratchet mechanism 505 is the core of precise control of the ball feeding action. It can strictly distinguish the pushing direction of the drive plate 506, triggering the flap 502 to open for feeding only when pushed forward (i.e., when the second push plate 411 resets to replenish grinding balls). When pushed in the reverse direction (i.e., when the second push plate 411 pushes out), only the drive plate 506 avoids the movement, and the flap 502 remains closed. This effectively avoids the problem of accidental feeding of grinding balls during the discharge process, achieving precise isolation between the ball feeding and discharge actions, and improving the reliability of ball feeding control. The entire feeding assembly 501 has a compact structure and does not require an additional independent drive source. Automatic control can be achieved by relying on the movement of the second push plate 411, reducing equipment manufacturing costs and energy consumption.

[0069] Example 5

[0070] To optimize the grinding performance of the inner liner, achieve stable and precise operation of the pusher plate linkage mechanism, and ensure the coordination of material discharge and ball addition, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0071] The inner liner 409 includes an inner liner 409, a liner 412, a first end cap 406, a second end cap 410, and a guide rod 413. The inner liner 409 is disposed inside the body 4, and the liner 412 is installed on the inner wall of the inner liner 409. The first end cap 406 and the second end cap 410 are respectively installed at both ends of the inner liner 409. The rotating shafts 402 at both ends of the body 4 are respectively fixed to the first end cap 406 and the second end cap 410. The inner liner 409 rotates inside the body 4 via the rotating shafts 402. The guide rod 413... Connected between the first end cap 406 and the second end cap 410, it serves to limit and guide the push plate linkage mechanism. The first end cap 406 and the second end cap 410 achieve a sealed enclosure of the inner liner 409, preventing material or grinding balls from leaking from both ends of the inner liner 409 during grinding. At the same time, it firmly connects the inner liner 409 to the rotating shaft 402 of the machine body 4, ensuring that the rotational power of the machine body 4 can be accurately transmitted to the inner liner 409, achieving synchronous rotation of the inner liner 409 and the machine body 4, and ensuring stable grinding conditions. The liner 412 on the inner wall of the inner liner 409 can enhance the collision and friction intensity between the grinding balls and the grinding parts, improving grinding efficiency. At the same time, the liner 412 can directly withstand the impact wear of the grinding balls, preventing damage to the inner liner 409 body, extending the service life of the inner liner 409, and the liner 412 is easy to disassemble and replace, reducing maintenance costs. The guide rod 413 can provide precise limiting and guiding for the first push plate 408 and the second push plate 411 of the push plate linkage mechanism, ensuring that the push plate can only move along the axial direction of the inner liner 409, avoiding deviation or jamming during the movement of the push plate, ensuring the linkage accuracy between the push plate and the discharge baffle 414 and the drive plate 506, and thus improving the stability of the discharge and ball-adding actions.

[0072] The push plate linkage mechanism includes a first push plate 408, a second push plate 411, a spring 407, a first connecting plate 415, a second bushing 419, a connecting rod 418, and a steel ring 417. Both the first push plate 408 and the second push plate 411 are sleeved on the feeding mechanism 7 and are limited and installed between the first end cover 406 and the second end cover 410 via a guide rod 413. The first push plate 408 is elastically connected to the first end cover 406 via the spring 407, achieving elastic reset. The first push plate 408 is connected to the discharge baffle 4 via the first connecting plate 415. 14. A connection is established to achieve linkage between the first push plate 408 and the discharge baffle 414. The second push plate 411 is rotatably mounted on the second bushing 419. One side surface of the second bushing 419 is connected to a steel ring 417 via a connecting rod 418. The steel ring 417 is used to contact the first push plate 408 and push it to move when the second push plate 411 moves. Both the first push plate 408 and the second push plate 411 are sleeved on the feeding mechanism 7 and limited by the guide rod 413, ensuring the coaxiality and stability of the push plate movement and preventing push plate offset from affecting the action transmission. The spring 407 enables the automatic elastic reset of the first push plate 408, eliminating the need for an additional reset drive component and simplifying the structure. After discharge, the first push plate 408 can drive the discharge baffle 414 to automatically close the discharge port 421 under the elastic force of the spring 407, preparing for the next round of grinding operations and improving the automation level of the operation. The first connecting plate 415 achieves rigid linkage between the first push plate 408 and the discharge baffle 414, ensuring that the movement of the first push plate 408 can be accurately transmitted to the discharge baffle 414, realizing the synchronous opening and closing of the discharge baffle 414, and avoiding the problem of delayed or incomplete opening and closing caused by transmission gap. The second push plate 411 is rotatably installed through the second bushing 419, which can adapt to the combined motion requirements of the inner liner 409 rotation and its own axial movement, reducing motion interference; the setting of the steel ring 417 increases the contact area between the second push plate 411 and the first push plate 408, making the pushing force of the second push plate 411 on the first push plate 408 more uniform, avoiding excessive local force that could cause component deformation, while reducing contact wear and improving the service life of the linkage mechanism.

[0073] The inner surface of the second bushing 419 is provided with a protrusion 420. When the locking switching mechanism locks the feeding mechanism 7, the second push plate 411 moves along the guide rod 702 through the cooperation of the protrusion 420 and the threaded groove 701 on the guide rod 702. During the rotation of the inner liner 409 driven by the machine body 4, the cooperation of the protrusion 420 and the threaded groove 701 constitutes a screw transmission mechanism. This design cleverly transforms the rotational motion of the inner liner 409 driven by the machine body 4 into the axial linear motion of the second push plate 411. There is no need to set up an additional power source to drive the movement of the second push plate 411, making full use of existing power, simplifying the equipment structure, and reducing energy consumption and manufacturing costs. The screw drive features smooth transmission, large thrust, and high transmission precision, ensuring that the second push plate 411 moves smoothly and accurately along the guide rod 702, thereby guaranteeing the accuracy of subsequent actions such as material feeding, opening of the discharge baffle 414, and replenishment of grinding balls. At the same time, this transmission method has a compact structure and occupies little space, which can be well adapted to the limited installation space inside the machine body 4, avoiding motion interference with other components and improving the rationality and compactness of the overall structure of the device.

[0074] Example 6

[0075] To achieve continuous and uniform feeding of the grinding parts, avoid clogging, and adapt to the requirements of the pusher drive, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0076] The feeding mechanism 7 includes a guide rod 702 and an auger 704. The auger 704 is located inside the guide rod 702. The guide rod 702 is located below the unloading assembly 501 and has an inlet 705. The guide rod 702 has a threaded groove 701. The feeding mechanism 7 is supported and installed on the base 2 by the second bearing seat 3. The grinding parts are conveyed to the inlet 705 by the auger 704 and then enter the machine body 4 through the inlet 705. The guide rod 702 provides a mounting carrier and protection for the auger 704, and at the same time guides the grinding parts to prevent them from scattering during the conveying process. The spiral conveying structure of the auger 704 can realize continuous and uniform feeding of the grinding parts, so that the grinding parts can be fully mixed and contacted with the grinding balls in the machine body 4, improving the uniformity and quality stability of grinding. Compared with the traditional gravity feeding method, it can effectively avoid the problem of feeding blockage. The feed inlet 705 is located below the unloading assembly 501, allowing the grinding parts and grinding balls to enter the machine body 4 in the same area, further improving their mixing efficiency. The threaded groove 701 on the guide rod 702 provides a transmission basis for the subsequent axial movement of the second push plate 411, realizing the functional coordination between the feeding mechanism 7 and the push plate linkage mechanism. The second bearing seat 3 provides stable support for the feeding mechanism 7, ensuring that the feeding mechanism 7 remains stable in both rotating and locked states, and preventing the feeding accuracy or transmission reliability from being affected by the shaking of the feeding mechanism 7.

[0077] Example 7

[0078] To achieve rapid and precise switching between two operating conditions of the feeding mechanism and improve the automation level and operational stability of the equipment, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0079] To achieve rapid and precise switching between two operating conditions of the feeding mechanism and improve the automation level and operational stability of the equipment, for example, such as Figures 1 to 10 As shown, the present invention also includes: The locking switching mechanism includes an electromagnet 404, a first gear 405, a second gear 416, a brake pad 301, and a keyway 703. The first gear 405 is mounted on the rotating shaft 402 of the machine body 4 facing the second bearing seat 3, and the electromagnet 404 is mounted on the back of the first gear 405. The brake pad 301 is mounted on the side surface of the second bearing seat 3 facing the machine body 4. The keyway 703 is formed on the outer surface of the feeding mechanism 7 located on the outer side of the machine body 4. The second gear 416 is slidably mounted on the feeding mechanism 7 by means of the keyway 703. The 16 mechanism integrates a strong magnet. By controlling the magnetic poles of the electromagnet 404, the second gear 416 is driven to move towards the first gear 405 or the brake pad 301, achieving meshing transmission between the second gear 416 and the first gear 405 or contact locking with the brake pad 301. The electromagnet 404's magnetic drive method enables rapid and precise switching of the second gear 416. Compared to traditional mechanical drive switching structures, it offers faster response, more convenient operation, and eliminates mechanical contact wear, effectively reducing the failure rate and extending the service life of the switching mechanism. The keyway 703 provides circumferential limiting for the second gear 416 and the feeding mechanism 7, ensuring that the second gear 416 can drive the feeding mechanism 7 to rotate synchronously, while also allowing the second gear 416 to slide axially along the feeding mechanism 7, meeting switching requirements. The meshing transmission between the first gear disc 405 and the second gear disc 416 ensures the synchronous rotation of the feeding mechanism 7 and the machine body 4, guaranteeing smooth feeding. The contact locking between the brake pad 301 and the second gear disc 416 quickly fixes the feeding mechanism 7, providing a stable transmission foundation for the axial movement of the push plate. The entire switching mechanism can switch between the two working conditions through electromagnetic control without manual intervention, improving the automation level of the equipment. Moreover, the switching process is smooth and will not cause impact on other transmission components, ensuring the stability of the device operation.

[0080] Example 8

[0081] To achieve automatic and coordinated switching between material discharge and grinding ball replenishment through simple control, thereby improving operational efficiency and reducing operational intensity, for example, such as Figures 1 to 10 As shown, the present invention also includes:

[0082] When the locking switching mechanism locks the feeding mechanism 7 and the drive mechanism drives the machine body 4 to rotate forward, the second push plate 411 moves along the guide rod 702 toward the first push plate 408, pushing the drive plate 506 in the opposite direction to fold and make room, while simultaneously pushing the first push plate 408 to move. Through the first connecting plate 415, the discharge baffle 414 is moved away from the discharge port 421 to achieve discharge. When the drive mechanism drives the machine body 4 to rotate in reverse, the second push plate 411 resets along the guide rod 702 and moves to the unloading assembly 501, pushing the drive plate 506 in the forward direction, causing the flip plate 502 to rotate in reverse and open, thus achieving automatic unloading of grinding balls. Through this simple control method of forward and reverse rotation of the machine body 4, the automatic switching and coordinated operation of the two key actions of unloading and replenishing grinding balls can be achieved without the need for a complex control system, simplifying the operation process and lowering the operation threshold. When the machine body 4 rotates forward, the second pusher plate 411 simultaneously completes two actions: avoiding the ball-adding mechanism and pushing the discharge mechanism, ensuring that the discharge process is not disturbed by the ball-adding mechanism and achieving smooth discharge. When the machine body 4 rotates in reverse, the second pusher plate 411 resets and simultaneously triggers automatic ball feeding, allowing ball replenishment to be completed quickly after discharge, improving operational continuity. The entire process requires no manual intervention, completely solving the problem of traditional ball mills requiring manual ball adding during shutdown, significantly improving operational efficiency and reducing the labor intensity of operators. At the same time, the actions are closely linked and logically clear, avoiding action conflicts or omissions, and improving the reliability and automation level of equipment operation.

[0083] Working principle:

[0084] Before the device is started, all components are in the initial reset state: In the push plate linkage mechanism, the first push plate 408 is reset to a position close to the first end cover 406 under the elastic force of the spring 407, and the second push plate 411 is reset to a position close to the second end cover 410; the discharge baffle 414 is in the closed state, sealing the discharge port 421; the flip plate 502 of the automatic ball feeding mechanism is kept closed under the torque of the torsion spring shaft, and the feeding hopper 5 stores grinding balls to be replenished; in the locking switching mechanism, the electromagnet 404 is not energized, and the second gear plate 416 is in the initial position under the magnetic balance between itself and the electromagnet 404, not meshing with the first gear plate 405 nor contacting the brake pad 301.

[0085] When the feeding mechanism 7 is activated, the auger 704 begins to rotate, and the external grinding parts are fed into the guide rod 702. Under the spiral pushing action of the auger 704, they move towards the machine body 4 and finally enter the inner liner 409 inside the machine body 4 through the feed port 705 on the guide rod 702. At the same time, the electromagnet 404 controlling the locking switching mechanism changes its magnetic poles. Using the attraction force between the electromagnet 404 and the strong magnet inside the second gear disk 416, the second gear disk 416 is driven to slide along the keyway 703 towards the first gear disk 405 until the second gear disk 416 and the first gear disk 405 are fully engaged. At this time, the drive mechanism starts, and the motor 1 drives the machine body 4 to rotate through the reducer 6. The machine body 4 drives the inner liner 409 to rotate synchronously through the rotating shaft 402. The second gear 416, which meshes with the first gear 405, drives the entire feeding mechanism 7 to rotate together with the machine body 4 through the keyway 703, ensuring that the grinding parts will not get stuck due to the relative movement between the feeding mechanism 7 and the inner liner 409 during the feeding process, thus achieving smooth and continuous feeding.

[0086] After the grinding parts are fed, the locking switching mechanism remains engaged, and the drive mechanism continuously drives the machine body 4 and the inner liner 409 to rotate at a constant speed. During the rotation of the inner liner 409, the grinding balls inside collide and rub against the grinding parts under the influence of centrifugal force and the inner wall liner 412 of the inner liner 409. The liner 412 effectively increases the grinding force between the grinding balls and the grinding parts, improving grinding efficiency and grinding accuracy. During this process, the first push plate 408 and the second push plate 411 of the push plate linkage mechanism rotate synchronously with the inner liner 409. Since the feeding mechanism 7 rotates at the same speed as the machine body 4, the guide rod 702 does not rotate relative to the inner liner 409. The second push plate 411 does not move axially under the cooperation of the protrusion 420 and the threaded groove 701. The discharge baffle 414 remains closed, ensuring that the grinding process is carried out in a closed space.

[0087] When the material has been ground to the preset requirements and needs to be discharged, the electromagnet 404 controlling the locking switching mechanism reverses its magnetic poles, causing the electromagnet 404 to generate a repulsive force on the second gear plate 416, driving the second gear plate 416 to slide along the keyway 703 away from the first gear plate 405 until the second gear plate 416 is in close contact with the brake pad 301 on the second bearing seat 3. The friction between the brake pad 301 and the second gear plate 416 locks the feeding mechanism 7, at which point the feeding mechanism 7 stops rotating, while the machine body 4 continues to rotate forward under the drive mechanism. Since the inner liner 409 rotates with the machine body 4, while the guide rod 702 remains fixed, the second push plate 411 forms a helical transmission engagement with the threaded groove 701 on the guide rod 702 through the protrusion 420 on the inner surface of the second bushing 419. The rotational motion of the inner liner 409 is converted into the linear motion of the second push plate 411 along the axial direction of the guide rod 702, and the second push plate 411 moves towards the first push plate 408.

[0088] During the movement of the second push plate 411, it first contacts the drive plate 506 of the automatic ball-adding mechanism and pushes the drive plate 506 in the opposite direction. Due to the unidirectional transmission characteristic of the ratchet mechanism 505 in the unloading assembly 501, only the drive plate 506 itself deflects and folds when pushed in the opposite direction, without driving the second connecting plate 503 and the flip plate 502 to move, thus achieving the clearance function. The second push plate 411, which continues to move, contacts the first push plate 408 through the steel ring 417 and pushes the first push plate 408. The first push plate 408 overcomes the elastic force of the spring 407 and moves towards the first end cover 406. At the same time, it drives the discharge baffle 414 to move synchronously through the first connecting plate 415, opening the discharge port 421. As the second push plate 411 continues to advance, the material that has been ground in the inner liner 409 is pushed towards the discharge port 421 and finally discharged from the discharge port 421, completing the discharge process.

[0089] After discharge, the control drive mechanism reverses, and the machine body 4 drives the inner liner 409 to rotate in the opposite direction. At this time, the feeding mechanism 7 is still locked. Under the spiral transmission of the protrusion 420 and the threaded groove 701, the second push plate 411 moves back to its original position along the guide rod 702 away from the first push plate 408. When the second push plate 411 moves to the unloading component 501 of the automatic ball feeding mechanism, it pushes the drive plate 506 in the forward direction. Due to the one-way transmission of the ratchet mechanism 505, the thrust of the drive plate 506 is transmitted to the second connecting plate 503 through the ratchet mechanism 505, causing the second connecting plate 503 to deflect, which in turn pulls the flap 502 to open against the torque of the torsion spring shaft. The grinding balls stored in the feeding hopper 5 fall into the inner liner 409 through the opening of the flap 502 under its own weight and the guidance of the guide plate 507, realizing the automatic replenishment of grinding balls.

[0090] After the grinding balls are replenished, the electromagnet 404 controlling the locking switching mechanism changes its magnetic pole again, driving the second gear plate 416 to disengage from the brake pad 301 and return to its initial position, or to re-engage with the first gear plate 405, preparing for the next round of feeding. Simultaneously, the drive mechanism stops reversing, the first push plate 408 resets under the elastic force of the spring 407, causing the discharge baffle 414 to close the discharge port 421; the flap 502 resets and closes under the torque of the torsion spring shaft, and the feed hopper 5 stops discharging. The device returns to its initial state, awaiting the next cycle of feeding, grinding, discharging, and ball replenishment.
