Description

Technical Field

[0001] This invention relates to the field of grinding ball manufacturing and conveying, specifically an automated conveyor for grinding ball manufacturing and forming. Background Technology

[0002] Grinding balls are key grinding media in ball mills used in industries such as mining, cement, and power. Their manufacturing quality directly affects grinding efficiency and energy consumption. During the manufacturing and forming process of grinding balls, it is necessary to transport the grinding balls at high temperatures between various processes, such as from the forging or hot rolling station to the quenching station, and from the quenching station to the tempering station.

[0003] Due to its simple structure and flexible layout, screw conveyors are widely used in the material conveying process of grinding ball manufacturing. The basic structure of a traditional screw conveyor includes a conveying cylinder, a screw pusher plate set inside the cylinder, and a power device that drives the screw pusher plate to rotate. Its working principle is to push the material to move along the axial direction of the conveying cylinder by the rotating screw pusher plate.

[0004] However, the following technical problems exist when using a traditional screw conveyor to transport grinding balls: First, since the grinding balls are spherical materials, they are prone to disordered accumulation and relative movement under the pushing action of the screw pusher plate in the conveying cylinder, resulting in mutual squeezing and collision. For grinding balls in a high-temperature state (usually 800℃-1000℃), their material strength is low, and mutual squeezing and collision can easily cause the grinding ball surface to be dented, deformed, or even cracked, which seriously affects the finished product quality and subsequent performance of the grinding balls.

[0005] Secondly, in traditional screw conveyors, the grinding balls are driven to a certain height by the rotation of the conveyor drum and then roll freely under gravity. The rolling of the grinding balls removes some of the surface burrs and dense oxide layers. However, in existing traditional screw conveyors, the grinding balls undergo uncontrollable, intermittent, and passive tumbling motion, which reduces the effectiveness of removing some surface burrs and dense oxide layers and fails to meet the manufacturing requirements of high-quality grinding balls.

[0006] Therefore, how to effectively solve the problem of mutual squeezing and collision of grinding balls during the conveying process while maintaining the basic conveying principle of screw conveyors, and at the same time improve the surface cleaning effect, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automated conveyor for manufacturing and forming grinding balls, including a support frame, a spiral conveyor cylinder rotatably arranged on the support frame, a feed chute fixedly connected to the left side of the support frame, a discharge chute fixedly connected to the right side of the support frame, and a separation mechanism arranged coaxially with the spiral conveyor cylinder on the support frame.

[0008] The spiral conveyor consists of an outer rotating drum and a spiral rod welded inside the rotating drum.

[0009] The separating mechanism includes a circular frame rotatably mounted on a support frame. Several partitions are fixedly installed at equal intervals on the left side inside the circular frame, and several rotating rollers are rotatably mounted at equal intervals on the right side inside the circular frame. The left end of the rotating roller is rotatably connected to the right end of the corresponding partition.

[0010] The partitions are arranged at an angle, with the distance between the left ends of two adjacent partitions being greater than the distance between their right ends, and the distance between two adjacent rollers matching the diameter of the grinding ball.

[0011] The feeding trough and the support frame are both equipped with a discharge assembly that discharges grinding balls one by one. The intermittent reciprocating rotation of the ring frame causes the drop grid formed by the left ends of two adjacent partitions and the spiral rod to move sequentially to the lower part of the feeding trough to receive the material.

[0012] Preferably, the ring frame includes a shaft rotatably mounted on a support frame, with ring plates fixedly connected to both the left and right sides of the shaft, and a disc plate fixedly installed at the right end of the shaft.

[0013] Preferably, a synchronous motor is fixedly installed on the right side of the support frame, and the output shaft of the synchronous motor is fixedly connected to the shaft rod.

[0014] Preferably, the discharge chute is composed of a semi-circular plate and a chute. The semi-circular plate is fixedly connected to the support frame. The semi-circular plate is arranged coaxially with the shaft and is located between the ring plate and the disc plate on the right side.

[0015] Preferably, an actuator motor is fixedly installed on the left side of the disc plate, and the output shaft of the actuator motor is connected to all the rotating rollers simultaneously through a belt drive unit.

[0016] Preferably, the support frame is rotatably provided with two sets of support wheels, one set of support wheels supports the rotating drum, and the other set of support wheels supports the ring frame.

[0017] Preferably, an asynchronous motor is fixedly installed on the left side of the support frame, and the output shaft of the asynchronous motor is connected to the support wheel of the support drum through a belt drive unit two.

[0018] Preferably, the right side of the feed trough has an inclined structure with the left side higher than the right side, and the width of the inclined section of the feed trough matches the diameter of the grinding balls, so that the grinding balls are arranged sequentially on the left and right sides of the feed trough.

[0019] Preferably, the discharge assembly includes a lifting frame that slides vertically at the right end of the feed chute, and two baffles are fixedly installed at the lower part of the lifting frame, with the right baffle being higher than the left baffle.

[0020] Preferably, a plate frame is fixedly installed on the support frame, and two hydraulic cylinders are fixedly connected to the plate frame. The telescopic sections of the hydraulic cylinders are fixedly connected to the lifting frame.

[0021] The beneficial effects of this invention are as follows: First, this invention uses several partitions and screw rods to form several independent discharge grids. With the help of the discharge assembly, the grinding balls are discharged one by one into the corresponding discharge grids. This allows each grinding ball to be separated from the others in different independent discharge grids during the rotation of the screw conveyor. This solves the problem of disordered accumulation and mutual squeezing and collision of grinding balls in traditional screw conveyors. It effectively avoids surface depressions, deformations and cracks caused by collisions of high-temperature grinding balls, and ensures the quality of the finished grinding balls.

[0022] Second, the present invention adopts a design in which the distance between two adjacent rotating rollers is matched with the diameter of the grinding ball. When the auger pushes the grinding ball to the position of the rotating roller, the two adjacent rotating rollers form a strict radial limit on the grinding ball to prevent the grinding ball from colliding with the rotating roller. At the same time, it drives each rotating roller to rotate continuously, so that the grinding ball generates an active and continuous rotational motion during the conveying process, which significantly improves the removal effect of burrs and dense oxide layer on the surface of the grinding ball and improves the manufacturing requirements of high-quality grinding balls.

[0023] Third, the present invention adopts a structure in which the partitions are arranged at an incline, so that the distance between the left ends of two adjacent partitions is greater than the distance between their right ends. This creates a larger receiving space in the initial area where the grinding balls fall from the feed chute into the discharge grid, which facilitates the accurate and smooth falling of the grinding balls into the discharge grid and avoids jamming or bouncing deviation caused by narrow discharge space. As the screw pushes the grinding balls to move axially, the space of the discharge grid where the grinding balls are located gradually narrows until the final width matches the diameter of the grinding balls. This guides the grinding balls smoothly to the precise limiting position between two adjacent rollers, providing a reliable position constraint for the subsequent active rotation of the grinding balls by the rollers.

[0024] Fourth, this invention uses a hydraulic cylinder to drive the lifting frame, which in turn drives two baffle plates to move up and down synchronously. This, combined with the arranging of grinding balls by the inclined section on the right side of the feed chute, ensures that during the lifting frame's ascent, the left baffle plate blocks the grinding balls arranged in the feed chute, while the right baffle plate releases the restriction on the end of a single grinding ball, allowing it to smoothly enter the corresponding drop compartment in the spiral conveyor. This achieves the quantitative discharge of grinding balls one by one, ensuring that only one grinding ball is fed into the spiral conveyor at a time. This avoids the accumulation or overlap of grinding balls at the feed end, providing a reliable feed guarantee for the subsequent separate conveying and independent rotation of grinding balls.

[0038] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0039] See Figure 1 , Figure 2 and Figure 3An automated conveyor for manufacturing grinding balls includes a support frame 1, a spiral conveyor 2 rotatably mounted on the support frame 1, a feed chute 11 fixedly connected to the left side of the support frame 1, a discharge chute 12 fixedly connected to the right side of the support frame 1, and a separation mechanism 3 coaxially arranged with the spiral conveyor 2 on the support frame 1.

[0040] During the conveying of grinding balls, the grinding balls roll one by one from the feed trough 11 into the screw conveyor 2. The grinding balls are independently separated by the separating mechanism 3, so that the grinding balls do not come into contact with each other during the entire conveying process. In the middle and later stages of the grinding ball conveying, the separating mechanism 3 can actively apply continuous rotation to the grinding balls, so that the grinding balls actively and continuously tumble during the conveying process, thereby improving the effect of removing some burrs and dense oxide layers from the surface of the grinding balls. The grinding balls conveyed to the right end of the screw conveyor 2 fall into the discharge trough 12. Finally, the grinding balls are discharged to the outside of the screw conveyor 2 along the discharge trough 12 under the action of gravity.

[0041] See Figure 5 , Figure 8 and Figure 9 The spiral conveyor 2 consists of an outer rotating drum 21 and a spiral rod 22 welded inside the rotating drum 21. When conveying grinding balls, the rotating drum 21 is continuously rotated, which causes the rotating drum 21 to drive the spiral rod 22 to rotate continuously. This causes the spiral rod 22 to continuously push the grinding balls falling into the inner wall of the rotating drum 21, causing the grinding balls to gradually move to the right.

[0042] It should be noted that, since the spiral conveyor 2 is a device that actively transports high-temperature grinding balls from a low position to a high position, in actual setup, the spiral conveyor 2 is arranged with the left side lower and the right side higher, and the specific tilt angle depends on the required lifting height of the grinding balls. Therefore, during the conveying process of the grinding balls, the grinding balls are always pressed against the right side of the spiral rod 22 under the action of gravity, so that the grinding balls will not move left or right and cause collisions during the conveying process.

[0043] See Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10 The separating mechanism 3 includes a circular frame 31 rotatably mounted on the support frame 1. Several partitions 32 are fixedly installed at equal intervals on the left side inside the circular frame 31. Several rotating rollers 33 are rotatably mounted at equal intervals on the right side inside the circular frame 31. The left end of the rotating roller 33 is rotatably connected to the right end of the corresponding partition 32.

[0044] See Figure 6 , Figure 8 , Figure 9 and Figure 10Several left and right arranged partitions 32 and spiral rods 22 are combined to form several material dropping grids, that is, the frame-shaped area formed between two adjacent partitions 32 and the left and right sections of the spiral rod 22. When conveying grinding balls, the ring frame 31 is rotated intermittently, so that the material dropping grids formed by the left ends of two adjacent partitions 32 and the spiral rods 22 move sequentially to the lower part of the feed trough 11 to receive the material, so that the grinding balls falling into the inside of the rotating drum 21 fall into each material dropping grid in sequence, so that each material dropping grid can independently separate each grinding ball and prevent the grinding balls from colliding with each other later.

[0045] Furthermore, when the screw rod 22 pushes the grinding ball to the right from the partition plate 32 to the rotating roller 33, the two adjacent rotating rollers 33 form a strict radial contact limit on the grinding ball, and drive each rotating roller 33 to rotate continuously, so that the rotating roller 33 drives the grinding ball to generate an active and continuous rotational motion during the conveying process, which significantly improves the removal effect of burrs and dense oxide layer on the surface of the grinding ball and improves the manufacturing requirements of high-quality grinding balls.

[0046] See Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 11 The feeding trough 11 and the support frame 1 are jointly provided with a discharge assembly 34 for discharging grinding balls one by one. The partitions 32 are arranged at an inclination, and the distance between the left ends of two adjacent partitions 32 is greater than the distance between their right ends. This makes the initial area where the grinding balls fall from the feeding trough 11 into the discharge grid form a larger receiving space, which facilitates the accurate and smooth falling of the grinding balls into the discharge grid and avoids the problem of jamming or bouncing and deviation caused by the narrow discharge space.

[0047] See Figure 6 , Figure 8 and Figure 10 The distance between two adjacent rotating rollers 33 is matched with the diameter of the grinding ball. As the screw rod 22 pushes the grinding ball to move axially, the space of the material drop grid where the grinding ball is located gradually narrows until the final width matches the diameter of the grinding ball, thereby smoothly guiding the grinding ball to the precise limiting position between two adjacent rotating rollers 33, providing a reliable position constraint for the subsequent rotating rollers 33 to drive the grinding ball to rotate actively.

[0048] To ensure that the grinding balls are fed one by one into the spiral conveyor cylinder 2, the present invention designs the following structure: (See attached diagram) Figure 2 , Figure 9 and Figure 11The feed trough 11 has an inclined structure with the left side higher than the right side. The width of the inclined section of the feed trough 11 matches the diameter of the grinding balls, so that the grinding balls are arranged in order from left to right on the feed trough 11. The discharge assembly 34 includes a lifting frame 341 that is slidably disposed on the right end of the feed trough 11. Two baffle plates 342 are fixedly installed on the lower part of the lifting frame 341. The right baffle plate 342 is higher than the left baffle plate 342. A plate frame 343 is fixedly installed on the support frame 1. Two hydraulic cylinders 344 are fixedly connected to the plate frame 343. The telescopic section of the hydraulic cylinder 344 is fixedly connected to the lifting frame 341.

[0049] When the discharge grid moves to the lower side of the inclined section of the feed trough 11, the telescopic section of the hydraulic cylinder 344 is retracted, causing the hydraulic cylinder 344 to drive the lifting frame 341 to move the two baffle plates 342 upward. During the upward movement of the two baffle plates 342, the left baffle plate 342 first blocks the grinding balls arranged in the feed trough 11, and then the right baffle plate 342 releases the restriction on the end grinding ball, allowing the grinding ball to smoothly enter the corresponding discharge grid.

[0050] Then, the two baffle plates 342 are lowered, so that the right baffle plate 342 first closes the end of the feed trough 11, and then the left baffle plate 342 releases its obstruction on the grinding balls arranged in the feed trough 11, so that these grinding balls slide down under the action of gravity, thereby replenishing the position of the already discharged grinding balls. The reciprocating lifting and lowering baffle plate 342 realizes the quantitative discharge of grinding balls one by one, ensuring that only one grinding ball is put into the screw conveyor 2 each time, avoiding the accumulation or overlap of grinding balls at the feed end, and providing a reliable feed guarantee for the subsequent separate conveying and independent rotation processing of grinding balls.

[0051] In order to allow the material discharge grid to move sequentially to the lower part of the feeding trough 11 to receive the material, the present invention designs the following structure: (See reference) Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The circular frame 31 includes a shaft 311 rotatably mounted on the support frame 1. Ring plates 312 are fixedly connected to both sides of the shaft 311. A disc plate 313 is fixedly installed at the right end of the shaft 311. A partition plate 32 is fixedly connected to the ring plate 312 on the left. A rotating roller 33 is rotatably connected to the ring plate 312 on the right. A synchronous motor 35 is fixedly installed on the right side of the support frame 1. The output shaft of the synchronous motor 35 is fixedly connected to the shaft 311.

[0052] During material feeding, the synchronous motor 35 drives the disc plate 313 and the two ring plates 312 to rotate synchronously via the drive shaft 311. This causes the two ring plates 312 to drive the rotating roller 33 and the partition plate 32 to rotate synchronously. In the initial state, the feeding grid formed by the two adjacent partition plates 32 at the front is located at the end of the feed trough 11. At this time, a grinding ball is discharged into the feeding grid. Subsequently, the synchronous motor 35 drives the partition plate 32 to rotate synchronously and uniformly in the same direction with the rotating drum 21. Each time the corresponding angle is rotated, that is, when each feeding grid corresponds to the position of the feed trough 11, a grinding ball is discharged into the feeding grid, thereby realizing the independent separation and arrangement of each grinding ball.

[0053] When the last discharge grid corresponds to the position of the feed trough 11, the rotating shaft 311 is slowly stopped and the shaft 311 is slowly reversed so that the discharge grid at the front corresponds to the end position of the feed trough 11 again. After the rotating drum 21 rotates one revolution, the shaft 311 is rotated again with the rotating drum 21 to continuously and independently convey the grinding balls.

[0054] It should be noted that the diameter of the rotating drum 21, the rotation speed of the rotating drum 21, the reverse rotation speed of the shaft 311, and the total number and angular range of the partitions 32 have all been obtained through repeated experiments by those skilled in the art, so that when the shaft 311 rotates, the grinding balls that are already in the discharge grid can stably maintain their position in the discharge grid, avoiding the phenomenon of the grinding balls jumping out of the discharge grid.

[0055] To facilitate the rotation of the rotating drum 21, the present invention designs the following structure: (See attached diagram) Figure 1 , Figure 2 , Figure 3 and Figure 4 Two sets of support wheels 13 are rotatably mounted on the support frame 1. One set of support wheels 13 supports the rotating drum 21, and the other set of support wheels 13 supports the circular frame 31, so that the long circular frame 31 and the bottom of the rotating drum 21 are supported to a certain extent, ensuring smooth rotation. An asynchronous motor 23 is fixedly installed on the left side of the support frame 1. The output shaft of the asynchronous motor 23 is connected to the support wheel 13 supporting the rotating drum 21 through the belt drive unit 2.

[0056] The belt drive unit 2 in this embodiment includes a driving pulley 2 fixedly mounted on the output shaft of the asynchronous motor 23, a driven pulley 2 fixedly mounted on one of the supporting rollers 13 of the bearing drum 21, and a belt 2 wound around the outside of the driving pulley 2 and the driven pulley 2.

[0057] When conveying grinding balls, the asynchronous motor 23 is started to drive the corresponding support roller 13 to rotate. The support roller 13 drives the rotating drum 21 to rotate continuously through friction, thereby realizing the continuous conveying of grinding balls.

[0058] To facilitate the guidance of the grinding ball, which has been moved to the right end of the rotating drum 21, to the outside of the rotating drum 21, the present invention designs the following structure: (See reference) Figure 3 , Figure 5 , Figure 6 and Figure 7 The discharge chute 12 is composed of a semi-circular plate 121 and a chute 122. The semi-circular plate 121 is fixedly connected to the support frame 1. The semi-circular plate 121 is coaxially arranged with the shaft 311. The semi-circular plate 121 is located between the ring plate 312 and the disc plate 313 on the right side.

[0059] The grinding balls, which have moved to the right end of the rotating drum 21, are pushed by the screw rod 22 and fall onto the semi-circular plate 121. The grinding balls are received by the arc-shaped inner surface of the semi-circular plate 121, so that the grinding balls are collected along the semi-circular plate 121 into the chute 122. Then the grinding balls roll out along the chute 122, thus completing the conveying of the grinding balls.

[0060] To facilitate the active rotation of the grinding balls by the rotating roller 33, the present invention designs the following structure: (See reference) Figure 3 , Figure 5 and Figure 6 An actuator motor 331 is fixedly installed on the left side of the disc plate 313. The output shaft of the actuator motor 331 is connected to all the rotating rollers 33 through a belt drive unit. When conveying grinding balls, the actuator motor 331 is started to drive all the rotating rollers 33 to rotate, so that the rotating rollers 33 continuously rotate throughout the conveying process by contacting the grinding balls.

[0061] The belt drive unit in this embodiment includes a drive pulley fixedly mounted on the output shaft of the actuator motor 331, a driven pulley fixedly mounted on each roller 33, and a belt that is wound around the outside of all the driven pulleys and the drive pulley.

[0062] It is worth noting that all parts of this invention are made of high-temperature resistant and wear-resistant materials.

[0063] Although the present invention adds structures such as a circular frame 31, a partition plate 32, a rotating roller 33, an actuator motor 331, and a discharge assembly 34 to the traditional screw conveyor, which increases the initial investment cost of the equipment to some extent, the present invention completely separates each grinding ball by using the independent discharge grid composed of the partition plate 32 and the screw rod 22 during the conveying process, avoiding mutual squeezing and collision between the high-temperature grinding balls, significantly reducing the scrap rate caused by surface depressions, deformation, and cracks, and reducing the manpower and material consumption of subsequent quality inspection and rework.

[0064] Meanwhile, by applying active and continuous rotational motion to the grinding balls through the rotating roller 33 in the middle and later stages of conveying, the removal effect of burrs and dense oxide layer on the surface of the grinding balls is effectively improved. The above comprehensive benefits can cover the increased initial investment due to structural optimization in a short period of time, so that the equipment of the present invention can show higher economy and practicality throughout the entire life cycle and has good industrial promotion and application value.
