Description

Technical Field

[0001] This invention relates to the field of ball mill technology for processing porcelain insulators, specifically a ball mill for processing porcelain insulators with an automatic feeding structure. Background Technology

[0002] The raw materials for porcelain insulators are usually in the form of blocks or granules, which need to be ground before they can be used for subsequent processing. Moreover, the raw materials for porcelain insulators are often a mixture of various mineral materials, such as clay, feldspar, and quartz. Uneven mixing can easily lead to quality problems in porcelain insulators during the firing process, such as cracking or insufficient strength caused by local composition differences. Therefore, ball mills are key equipment in the processing of porcelain insulators.

[0003] A ball mill for processing porcelain insulators with automatic feeding function, disclosed in patent publication number CN114146781B, includes a main body with a grinding cavity inside. The inner wall of the grinding cavity is lined with an inner plate, and a first support and a second support are respectively provided at both ends of the main body. This invention connects the grinding cavity to a conveying pipe at the lower end of the main body via a feeding pipe. A spiral conveying rod is installed inside the conveying pipe. During the grinding process, the ground material passes through a filter plate at the lower end of the grinding cavity and enters the feeding pipe, then into the conveying pipe. Simultaneously, a power motor drives the spiral conveying rod inside the conveying pipe via a second transmission mechanism to transport the material, which is finally discharged from the material outlet at one end of the conveying pipe. Throughout the grinding process, the feeding speed is adjusted by regulating the feed valve of the feed pipe, thus achieving simultaneous feeding, processing, and discharging.

[0004] However, in the ball mills mentioned above, the material enters the grinding cavity through the conveying pipe, which cannot guarantee the accuracy of the feeding. The continuous feeding of material from the conveying pipe can easily lead to excessive raw material, resulting in excessive load on the ball mill during operation. Furthermore, it cannot guarantee the uniform distribution of material, which can easily damage the ball mill, reduce its service life, reduce the grinding rate, and fail to guarantee the grinding quality and ensure uniform crushing of the material. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a ball mill for processing ceramic insulators with an automatic feeding structure, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ball mill for processing porcelain insulators with an automatic feeding structure, comprising a fixed frame and a power system. The ball mill body passes through the fixed frame, and a large gear is fixed to the outer wall of the ball mill body. The power system includes a motor and a small gear. The motor is located at the bottom of the ball mill body, and a small gear is fixed to the output end of the motor. The small gear meshes with the large gear. A feeding device is fixed to the left side of the ball mill body, and a discharging device is fixed to the right side of the ball mill body. The feeding device is equipped with a control mechanism for intermittent feeding of the ball mill. The control mechanism is equipped with a striking mechanism for striking the inner wall of the ball mill body and an auxiliary mechanism for pushing the material towards the center.

[0007] The control mechanism includes a first fixed plate, a first spring, a movable plate, a movable rod, a liner, a second fixed plate, a protruding rod, and a sliding groove. The first fixed plate is fixedly connected to the inner wall of the ball mill body and has a discharge hole. The inner wall of the feeding device is fixedly connected to one end of the first spring, and the other end of the first spring is fixed to the movable plate. The movable plate passes through the side wall of the feeding device and is slidably connected at the penetration point. When the ball mill body rotates, the first fixed plate on its inner wall rotates and pushes the movable rod to the left, causing the movable plate to move to the left and open, allowing the feeding port to discharge material. In conjunction with the first spring, the movable plate and the movable rod reciprocate, changing the continuous feeding from the feeding port to intermittent feeding.

[0008] According to the above technical solution, a movable rod is fixed to the side wall of the movable plate away from the first spring. The movable rod is Z-shaped. The end of the movable rod away from the movable plate is attached to the first fixed plate. A liner passes through the feed end of the ball mill body and is rotatably connected at the through-hole.

[0009] According to the above technical solution, a second fixed plate is fixed to the inner wall of the liner, a protruding rod is fixed to the upper surface of the movable rod, and a sliding groove is provided on the inner wall of the liner. The end of the protruding rod away from the movable rod is slidably connected to the inner wall of the sliding groove. When the movable rod moves to the left, it drives the liner to rotate in conjunction with the protruding rod and the sliding groove. When the liner rotates, it drives the second fixed plate to rotate, bringing the material and steel ball to a higher place so that the steel ball can obtain greater kinetic energy and more effectively crush the material when it impacts it, thereby improving the grinding efficiency.

[0010] According to the above technical solution, the striking mechanism includes a fixed block, a first hinge rod, a second hinge rod, a movable block, a second spring, a slider, a baffle, an obtuse-angle hinge rod, a third hinge rod, and a small iron block. The fixed block is fixedly connected to the upper surface of the movable rod, and the first hinge rod is hinged to the upper surface of the fixed block.

[0011] According to the above technical solution, the first hinge rod is hinged to the end away from the fixed block with a second hinge rod. The movable rod passes through the movable block and is slidably connected at the point of penetration. The upper surface of the movable block and the end of the second hinge rod away from the first hinge rod are hinged together. The right side wall of the movable block and one end of the second spring are fixedly connected. The other end of the second spring is fixedly connected to the left side wall of the fixed block.

[0012] According to the above technical solution, the bottom surface of the movable rod is provided with a movable groove, a slider slides in the movable groove, a baffle is hinged to the bottom surface of the left end of the slider, a protrusion is fixed to the outer wall of the hinge end of the second hinge rod and the first hinge rod, the protrusion passes through the obtuse angle hinge rod and is rotatably connected at the point of penetration, and the end of the obtuse angle hinge rod away from the protrusion is hinged to the right side wall of the baffle.

[0013] According to the above technical solution, the bottom right end of the slider is hinged to the upper end of the third hinge rod, the bottom end of the movable rod is hinged to the upper end of the third hinge rod, the bottom ends of the two sets of third hinge rods are hinged to each other, and small iron blocks are simultaneously hinged at the hinge points of the two sets of third hinge rods.

[0014] According to the above technical solution, the auxiliary mechanism includes a telescopic rod, a sliding plate, and a fourth hinge rod. The telescopic rod is fixedly connected to the bottom surface of the movable rod. The telescopic rod passes through the sliding plate and is slidably connected at the point of penetration. The fourth hinge rod is hinged to the left side wall of the sliding plate, and the end of the fourth hinge rod away from the sliding plate is hinged to the right side wall of the movable block.

[0015] This invention provides a ball mill for processing ceramic insulators with an automatic feeding structure.

[0016] It has the following beneficial effects:

[0017] 1. In this invention, when the main body of the ball mill rotates, the rotation of the first fixed plate on its inner wall pushes the movable rod to the left, causing the movable plate to move to the left and open, allowing material to be fed into the inlet. The first spring then causes the movable plate and the movable rod to reciprocate, changing the continuous feeding from continuous to intermittent feeding, making the material feeding more precise and preventing excessive material intake. The leftward movement of the movable rod, in conjunction with the convex rod and sliding groove, causes the liner to rotate. The rotation of the liner causes the second fixed plate to rotate, carrying the material and steel balls to a higher position, allowing the steel balls to gain greater kinetic energy and more effectively crush the material upon impact, improving grinding efficiency and accelerating the grinding process.

[0018] 2. In this invention, the movable rod moves to the left, causing the fixed block to move to the left as well. This, in conjunction with the movable block, causes the first and second hinge rods to rotate, allowing the hinge points to strike the inner wall of the ball mill body, preventing material from adhering to the inner wall and affecting the grinding effect. The rotation of the first and second hinge rods causes the obtuse-angle hinge rod to rotate and move. A small iron block detects the material height to determine if there is enough material. When there is enough material, the third hinge rod fixes the slider, and the obtuse-angle hinge rod pulls the baffle to close, stopping the feeding. This allows the baffle to automatically change the feeding state, preventing the addition of material before the material inside the ball mill body is fully ground, resulting in more thorough grinding. Furthermore, this invention prevents the ball mill body from operating at full load for extended periods, thereby reducing maintenance costs and extending the equipment's service life.

[0019] 3. In this invention, the movable rod can move to the left, causing the telescopic rod and the sliding plate to move to the left. This, in conjunction with the movable block, drives the fourth hinge rod to rotate, causing the sliding plate to descend. When the movable rod moves to the right, it also drives the sliding plate to the right, pushing the material towards the center of the ball mill body. This makes the steel balls and material more evenly distributed, ensuring grinding efficiency and quality, while preventing material from accumulating at the feed inlet and affecting the feeding process.

[0028] 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.

[0029] Please see Figures 1-7 One embodiment of the present invention is as follows: a ball mill for processing porcelain insulators with an automatic feeding structure, comprising a fixed frame 1 and a power system 2. The ball mill body 3 passes through the fixed frame 1. A large gear is fixed to the outer wall of the ball mill body 3. The power system 2 includes a motor and a small gear. The motor is located at the bottom of the ball mill body 3. A small gear is fixed to the output end of the motor. When the motor is started, the motor drives the small gear to rotate. The small gear meshes with the large gear. When the small gear rotates, it drives the large gear to rotate. The rotation of the large gear drives the ball mill body 3 to rotate. A feeding device 4 is fixed to the left side of the ball mill body 3. The material to be processed is inverted above the feeding device 4 and fed through the feeding device 4. A discharging device 5 is fixed to the right side of the ball mill. The feeding device 4 is provided with a control mechanism 6 for intermittent feeding of the ball mill.

[0030] The control mechanism 6 includes a first fixed plate 61, a first spring 62, a movable plate 63, a movable rod 64, a liner 65, a second fixed plate 66, a protruding rod 67, and a sliding groove 68. The first fixed plate 61 is fixedly connected to the inner wall of the ball mill body 3. When the ball mill body 3 rotates, the first fixed plate 61 inside it also rotates. The first fixed plate 61 has a discharge hole. The inner wall of the feeding device 4 is fixedly connected to one end of the first spring 62, and the other end of the first spring 62 is fixed with a movable plate 63. The movable plate 63 moves to the left to compress the first spring 62. The movable plate 63 penetrates the side wall of the feeding device 4, and the penetration point is slidably connected. The movable plate 63 moves away from the side wall of the feeding device 4. A movable rod 64 is fixed to the side wall of the first spring 62. Moving the movable rod 64 to the left moves the movable plate 63 to the left, exposing the feed inlet and allowing the feeding device 4 to feed material. The movable rod 64 is Z-shaped, with the end of the movable rod 64 away from the movable plate 63 fitting against the first fixed plate 61. Since the first fixed plate 61 is inclined, when the first fixed plate 61 rotates, it pushes the movable rod 64, which is fitted against it, to move to the left. A liner 65 passes through the feed end of the ball mill body 3, and the through-hole is rotatably connected. A second fixed plate 66 is fixed to the inner wall of the liner 65. When the liner 65 rotates, it drives the second fixed plate 66 to rotate. The material and steel balls inside the ball mill body 3 are brought to a higher position and then dropped. A protruding rod 67 is fixed to the upper surface of the movable rod 64. When the movable rod 64 moves to the left, it drives the protruding rod 67 to move to the left. A sliding groove 68 is provided on the inner wall of the liner 65. The end of the protruding rod 67 away from the movable rod 64 is slidably connected to the inner wall of the sliding groove 68. Because the protruding rod 67 and the sliding groove 68 are in contact and can only slide along the sliding groove 68, the protruding rod 67 slides along the sliding groove 68 while moving to the left, causing the sliding groove 68 to rotate. Therefore, when the protruding rod 67 moves, it drives the liner 65 to rotate. This control mechanism 6, when the ball mill body 3 rotates, controls the rotation of the liner 65 through its internal... The first fixed plate 61 of the wall rotates, pushing the movable rod 64 to the left, which in turn moves the movable plate 63 to the left to open, allowing the feed inlet to discharge material. In conjunction with the first spring 62, the movable plate 63 and the movable rod 64 reciprocate, changing the continuous discharge from the feed inlet to intermittent discharge, making the material feeding more precise and avoiding excessive raw material. The leftward movement of the movable rod 64, in conjunction with the protruding rod 67 and the sliding groove 68, drives the liner 65 to rotate. When the liner 65 rotates, it drives the second fixed plate 66 to rotate, bringing the material and steel ball to a higher position so that the steel ball gains greater kinetic energy and more effectively crushes the material when it impacts it, improving grinding efficiency and accelerating the grinding process.

[0031] In this embodiment, during operation: the motor in the power system 2 starts, driving the small gear to rotate. The rotation of the small gear drives the large gear meshing with it to rotate as well. The rotation of the large gear drives the ball mill body 3 to rotate as well. When the ball mill body 3 rotates, its internal first fixed plate 61 also rotates. Since the first fixed plate 61 is tilted, its rotation pushes the movable rod 64 to the left. The leftward movement of the movable rod 64 causes the movable plate 63 to move to the left, exposing the feed inlet and allowing the feeding device 4 to discharge material. The leftward movement of the movable plate 63 compresses the first spring 62. As the first fixed plate 61 continues to rotate, the movable rod 64 does not mesh with the first fixed plate 62. When the fixed plate 61 makes contact, the movable plate 63 moves to the right under the thrust of the first spring 62, which drives the movable rod 64 to move to the right. When the movable plate 63 moves to the right, it closes the feed port and stops feeding. When the movable rod 64 moves to the left, it drives the protruding rod 67 to move to the left. Since the protruding rod 67 is in contact with the sliding groove 68 and can only slide along the sliding groove 68, the protruding rod 67 slides along the sliding groove 68 while moving to the left, which drives the sliding groove 68 to rotate. Therefore, when the protruding rod 67 moves, it drives the liner 65 to rotate. When the liner 65 rotates, it drives the second fixed plate 66 to rotate. The rotation of the second fixed plate 66 carries the material and steel balls in the ball mill body 3 to a higher position for them to fall.

[0032] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the control mechanism 6 is provided with a striking mechanism 7 for striking the inner wall of the ball mill body 3, and the control mechanism 6 is provided with an auxiliary mechanism 8 for pushing the material towards the center. The striking mechanism 7 includes a fixed block 71, a first hinge rod 72, a second hinge rod 73, a movable block 74, a second spring 75, a slider 76, a baffle 77, an obtuse-angle hinge rod 78, a third hinge rod 79, and a small iron block 710. The fixed block 71 is fixedly connected to the upper surface of the movable rod 64. When the movable rod 64 moves to the left, it drives the fixed block 71 to move to the left. The upper surface of the fixed block 71 is hinged to the first hinge rod 72, and the end of the first hinge rod 72 away from the fixed block 71 is hinged to the second hinge rod 73. The movable rod 64 passes through... The movable block 74 is slidably connected at the through-hole. When the movable rod 64 moves to the left, it drives the movable block 74 to move to the left as well. When the movable block 74 contacts the liner 65, the movable rod 64 continues to move, and the movable block 74 begins to slide relative to the movable rod 64. The fixed block 71 continues to move with the movable rod 64, and the distance between it and the movable block 74 becomes smaller and smaller. The upper surface of the movable block 74 and the end of the second hinge rod 73 away from the first hinge rod 72 are hinged. When the distance between the fixed block 71 and the movable block 74 decreases, the first hinge rod 72 and the second hinge rod 73 above the fixed block 71 and the movable block 74 rotate. The closer the bottom ends of the first hinge rod 72 and the second hinge rod 73 are, the closer the hinge point of the first hinge rod 72 and the second hinge rod 73 becomes. The higher the moving rod 64, the higher the hinge point of the first hinge rod 72 and the second hinge rod 73 rises, striking the liner 65. The right side wall of the movable block 74 and one end of the second spring 75 are fixedly connected, and the other end of the second spring 75 is fixedly connected to the left side wall of the fixed block 71. The distance between the fixed block 71 and the movable block 74 becomes smaller and smaller, compressing the second spring 75. When the movable rod 64 moves to the right, due to the elastic force of the second spring 75, the distance between the fixed block 71 and the movable block 74 becomes larger and larger. At this time, the first hinge rod 72 and the second hinge rod 73 rotate, causing their hinge point to become lower and lower. The bottom surface of the movable rod 64 has a movable groove, and a slider 76 slides in the movable groove. A baffle 77 is hinged to the bottom surface of the left end of the slider 76. The second hinge rod 73 and the first hinge rod 74 are connected to the second hinge rod 74. A protrusion is fixed to the outer wall of the hinge end of the connecting rod 72. The protrusion passes through the obtuse-angle hinge rod 78, and the connection point is rotatably connected. When the hinge point of the first hinge rod 72 and the second hinge rod 73 rises, it drives one end of the obtuse-angle hinge rod 78 to move upward. When one end of the obtuse-angle hinge rod 78 moves upward, its other end first moves to the right. The end of the obtuse-angle hinge rod 78 away from the protrusion is hinged to the right side wall of the baffle 77. When the obtuse-angle hinge rod 78 moves upward, it drives the baffle 77 to rotate, changing the baffle 77 from a normally open state to a closed state, preventing material from entering the ball mill body 3. The bottom surface of the right end of the slider 76 is hinged to the upper end of the third hinge rod 79, and the bottom surface of the movable rod 64 is hinged to the upper end of the third hinge rod 79. The bottom ends of the two sets of third hinge rods 79 are hinged to each other.Small iron blocks 710 are simultaneously hinged at the hinge points of the two sets of third hinge rods 79. If there is a large amount of material and steel balls inside the ball mill body 3, and the accumulation height is high, the small iron blocks 710 cannot descend above the material. The height of the small iron blocks 710 is fixed relative to the movable rod 64, thus fixing the third hinge rods 79. With the third hinge rods 79 fixed, the slider 76 cannot slide to the right relative to the movable rod 64, keeping the position of the baffle 77 relative to the movable rod 64 unchanged. When the obtuse-angle hinge rod 78 moves upward, it drives the baffle 77 to rotate, changing the baffle 77 from a normally open state to a closed state, preventing material from entering the ball mill body 3. The striking mechanism 7 can drive the fixed block 71 to move to the left by moving the movable rod 64, cooperating with the movable block 74 to make the first hinge rod The first hinge rod 72 and the second hinge rod 73 rotate, causing the hinge point to strike the inner wall of the ball mill body 3, preventing material from adhering to the inner wall and affecting the grinding effect. The rotation of the first hinge rod 72 and the second hinge rod 73 drives the obtuse-angle hinge rod 78 to rotate and move. A small iron block 710 detects the material height to determine if there is enough material. When there is enough material, it cooperates with the third hinge rod 79 to fix the slider 76, and the obtuse-angle hinge rod 78 pulls the baffle 77 to close, stopping the feeding. This allows the baffle 77 to automatically change the feeding state, preventing the addition of material before the material inside the ball mill body 3 is fully ground, ensuring more thorough grinding, and preventing the ball mill body 3 from running at full load for extended periods, thereby reducing maintenance costs and extending the equipment's service life.

[0033] The auxiliary mechanism 8 includes a telescopic rod 81, a sliding plate 82, and a fourth hinge rod 83. The telescopic rod 81 is fixedly connected to the bottom surface of the movable rod 64. The telescopic rod 81 passes through the sliding plate 82 and is slidably connected at the point of penetration. When the movable rod 64 moves to the left, it drives the telescopic rod 81 and the sliding plate 82 to move to the left. The fourth hinge rod 83 is hinged to the left side wall of the sliding plate 82. When the fourth hinge rod 83 rotates clockwise, it pushes the sliding plate 82 downward. The end of the fourth hinge rod 83 away from the sliding plate 82 is hinged to the right side wall of the movable block 74. Since the movable block 74 moves to the right relative to the movable rod 64, the distance between the movable block 74 and the telescopic rod 81 decreases, driving the fourth hinge rod 83. The rotating mechanism causes the sliding plate 82 to move downwards and insert into the material. When the movable rod 64 moves to the right, it drives the telescopic rod 81 and the sliding plate 82 to move to the right. The sliding plate 82 pushes the material towards the center of the ball mill body 3. The auxiliary mechanism 8 can also drive the telescopic rod 81 and the sliding plate 82 to the left by moving the movable rod 64 to the left. This, in conjunction with the movable block 74, drives the fourth hinge rod 83 to rotate, causing the sliding plate 82 to descend. When the movable rod 64 moves to the right, it also drives the sliding plate 82 to the right, pushing the material towards the center of the ball mill body 3. This makes the steel balls and material more evenly distributed, ensuring grinding efficiency and quality, while preventing material from accumulating at the feed inlet and affecting the feeding process.

[0034] In this embodiment, during operation: when the movable rod 64 moves to the left, it drives the fixed block 71 and the movable block 74 to move to the left together. When the movable block 74 contacts the liner 65, the movable rod 64 continues to move, and the movable block 74 begins to slide relative to the movable rod 64. The fixed block 71 continues to move with the movable rod 64, and the distance between it and the movable block 74 becomes smaller and smaller, compressing the second spring 75. When the distance between the fixed block 71 and the movable block 74 decreases, the first hinge rod 72 and the second hinge rod 73 above the fixed block 71 and the movable block 74 rotate. The closer the bottom ends of the second hinge rod 73 are, the higher the hinge point between the first hinge rod 72 and the second hinge rod 73 becomes. This increased hinge point causes the liner plate 65 to be struck, shaking off the material adhering to the inner wall of the ball mill body 3 after wet grinding. When the movable rod 64 moves to the right, the distance between the fixed block 71 and the movable block 74 increases due to the elastic force of the second spring 75. At this time, the first hinge rod 72 and the second hinge rod 73 rotate, causing their hinge points to decrease. Simultaneously, as the hinge points of the first hinge rod 72 and the second hinge rod 73 increase... The obtuse-angle hinge rod 78 moves one end upward, and when it moves upward, the other end moves to the right first. If there is a large amount of material and steel balls in the ball mill body 3, and the pile is high, the small iron block 710 cannot descend above the material. The height of the small iron block 710 is fixed relative to the movable rod 64, thus fixing the third hinge rod 79. With the third hinge rod 79 fixed, the slider 76 cannot slide to the right relative to the movable rod 64, keeping the position of the baffle 77 relative to the movable rod 64 unchanged. When the obtuse-angle hinge rod 78 moves upward, it drives the baffle 77 to move forward. The rotation of the baffle 77 changes the baffle from the normally open state to the closed state, preventing material from entering the ball mill body 3. When there is less material and steel balls in the ball mill body 3, the accumulation height is low and cannot prevent the small iron block 710 from falling. The falling of the small iron block 710 drives the third hinge rod 79 to rotate. When the third hinge rod 79 rotates, it drives the slider 76 to slide to the right relative to the movable rod 64. At this time, one end of the obtuse angle hinge rod 78 moves upward, and the other end drives the baffle 77 and the slider 76 to slide to the right together. The baffle 77 is still in the normally open state, allowing the material to continue to be fed from the feed inlet.

[0035] When the movable rod 64 moves to the left, it causes the telescopic rod 81 and the sliding plate 82 to move to the left. Since the movable block 74 moves to the right relative to the movable rod 64, the distance between the movable block 74 and the telescopic rod 81 decreases, causing the fourth hinge rod 83 to rotate. When the fourth hinge rod 83 rotates clockwise, it pushes the sliding plate 82 downward and inserts it into the material. When the movable rod 64 moves to the right, it causes the telescopic rod 81 and the sliding plate 82 to move to the right. The sliding plate 82 pushes the material towards the center of the ball mill body 3. At the same time, due to the elastic force of the second spring 75, the distance between the movable block 74 and the telescopic rod 81 increases, causing the fourth hinge rod 83 to rotate counterclockwise, pulling the sliding plate 82 upward and away from the material.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
