Description

Technical Field

[0001] The utility model relates to the technical field of transmission mechanisms, in particular to a ball forming machine driving device. Background Art

[0002] Ball forming machines are specialized equipment used in cement, chemical, and furnace materials industries. The upward-facing, tilted hopper of the ball forming machine is used to hold the material. During operation, the hopper rotates continuously, and the material, combined with the action of a binder, forms a ball.

[0003] The rotating shaft, motor shaft, and reducer shaft of a common pelletizing machine are coaxially arranged. However, the hopper part of the pelletizing machine is heavier and produces continuous vibration during operation. Therefore, in actual use, the connection between the rotating shaft and the reducer shaft is difficult to maintain a coaxial state. Once eccentricity occurs, the entire system is easily damaged, and it is necessary to shut down for maintenance. If the material in the hopper cannot maintain a continuous state of motion, it will aggregate into larger lumps. At this time, the batch of materials cannot be directly used, which will have a certain impact on production. Therefore, it is necessary to design a transmission device with better stability. Utility Model Content

[0004] The purpose of the utility model is to provide a ball forming machine driving device, which can not only effectively improve the stability of the ball forming machine operation, but also can continue to operate for a period of time when the driving mechanism is damaged.

[0005] The embodiments of the present invention are realized through the following technical solutions: the ball forming machine driving device of the present invention includes a partition, a rotating shaft arranged on the upper side of the partition, a driving shaft arranged on the lower side of the partition, a sprocket assembly for connecting the rotating shaft and the driving shaft, and a first supporting device, a second supporting device and a spare supporting device for supporting the driving shaft; the axial direction of the rotating shaft is parallel to the axial direction of the driving shaft; the first supporting device, the second supporting device and the spare supporting device are distributed along the axial direction of the rotating shaft; the rotating shaft is connected to the ball forming machine, and the driving shaft is connected to a gearbox and a motor.

[0006] Furthermore, the sprocket assembly is provided at the ends of the rotating shaft and the driving shaft.

[0007] Furthermore, the rotating shaft and the driving shaft are arranged on the same side of the sprocket assembly.

[0008] Furthermore, the sprocket assembly includes sprockets provided at the ends of the rotating shaft and the driving shaft, and a chain for connecting a pair of the sprockets.

[0009] Furthermore, the rotating shaft and the driving shaft are each provided with a pair of sprockets, and the chains are provided with a pair.

[0010] Furthermore, along the direction from the sprocket assembly to the pelletizing machine, the first supporting device, the second supporting device and the spare supporting device are distributed in sequence.

[0011] Furthermore, the first supporting device and the second supporting device have the same structure; the first supporting device includes a first bearing sleeved on the outer wall of the rotating shaft, a first ring sleeved on the outer wall of the first bearing, a first support rod supporting the first ring, a first support plate provided at the lower end of the first support rod, and a first sealing cover sleeved on the outer wall of the first ring; the first sealing cover is connected to the rotating shaft in a sealing and rotatable manner, lubricating oil is provided in the first sealing cover, and the first support plate is connected to the partition.

[0012] Furthermore, the backup support device includes a second bearing sleeved on the outer wall of the rotating shaft, a second ring sleeved on the outer wall of the second bearing, a second support rod for supporting the second ring, a sleeve provided at the lower end of the second support rod, a second support plate provided at the lower end of the sleeve, side plates provided on both sides of the second support rod, and bolts threadedly connected to the side plates; a second sealing cover is sealingly and rotatably connected to the rotating shaft, lubricating oil is provided in the second sealing cover, the lower end of the second support is slidably provided in the sleeve, the lower end of the bolt abuts against the second support plate, and the second support plate is connected to the partition.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the ball forming machine driving device of the utility model, when in use, the motor outputs power to the drive shaft through the reducer, and the drive shaft then outputs power to the rotating shaft through the sprocket assembly, and finally drives the ball forming machine to operate through the rotating shaft. In this way, the motor, reducer, and rotating shaft do not need to be located on the same axis, which can well avoid eccentric failures caused by vibration during the operation of the ball forming machine, and the operation of the entire device is more stable. Moreover, after the sprocket assembly is changed to drive, the shear force on the end of the rotating shaft becomes larger, so a first device and a second supporting device are provided at the end of the rotating shaft, wherein the second supporting device near the ball forming machine is subjected to greater pressure and is more prone to damage. Therefore, when it fails, a spare supporting device can be temporarily used to assist in supporting the rotating shaft, which can reduce the force applied to the second supporting device, so that the device can continue to operate for a period of time without having to stop for maintenance immediately. During this time, the production and maintenance processes can be reasonably arranged, which can effectively ensure the efficient operation of production. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example

[0025] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3As shown, the ball forming machine driving device of this embodiment includes a partition 10, a rotating shaft 13 provided on the upper side of the partition 10, a driving shaft 12 provided on the lower side of the partition 10, a sprocket 14 assembly for connecting the rotating shaft 13 and the driving shaft 12, and a first supporting device 20, a second supporting device 30 and a backup supporting device 40 for supporting the driving shaft 12; the axial direction of the rotating shaft 13 is parallel to the axial direction of the driving shaft 12; the first supporting device 20, the second supporting device 30 and the backup supporting device 40 are distributed along the axial direction of the rotating shaft 13; the rotating shaft 13 is connected to the ball forming machine, and the driving shaft 12 is connected to the gearbox and the motor. Specifically, when in use, the motor outputs power to the driving shaft 12 through the reducer 11, and the driving shaft 12 then outputs power to the rotating shaft 13 through the sprocket 14 assembly, and finally drives the ball forming machine to operate through the rotating shaft 13. In this way, the motor, the reducer 11 and the rotating shaft 13 do not need to be located on the same axis, which can well avoid eccentric faults caused by vibration during the operation of the ball forming machine. After the transmission is changed to the sprocket 14 assembly, the shear force on the end of the rotating shaft 13 becomes greater, so a first device and a second supporting device 30 are set at the end of the rotating shaft 13. Among them, the second supporting device 30 close to the ball forming machine is subjected to greater pressure and is more easily damaged. Therefore, when it fails, the spare supporting device 40 can be temporarily used to assist in supporting the rotating shaft 13. This can reduce the force on the second supporting device 30, so that the device can continue to operate for a period of time without the need to stop for maintenance immediately. During this time, the production and maintenance processes can be reasonably arranged, which can effectively ensure the efficient production.

[0026] The sprocket 14 assembly in this embodiment is arranged at the end of the rotating shaft 13 and the driving shaft 12. The rotating shaft 13 and the driving shaft 12 are arranged on the same side of the sprocket 14 assembly. Specifically, this is more convenient for installation and disassembly.

[0027] The sprocket 14 assembly in this embodiment includes sprockets 14 disposed at the ends of the rotating shaft 13 and the drive shaft 12, and a chain 15 connecting the pair of sprockets 14. A pair of sprockets 14 is provided on each of the rotating shaft 13 and the drive shaft 12, and a pair of chains 15 is provided. Specifically, because the pelletizing machine is subject to high loads and vibrations, the use of a pair of sprockets 14 and chains 15 can better reduce the stress on a single sprocket 14 and chain 15.

[0028] In this embodiment, along the direction from the sprocket 14 assembly to the ball forming machine, the first support device 20, the second support device 30 and the spare support device 40 are distributed in sequence. The first support device 20 and the second support device 30 have the same structure; the first support device 20 includes a first bearing sleeved on the outer wall of the rotating shaft 13, a first ring sleeved on the outer wall of the first bearing, a first support rod 22 supporting the first ring, a first support plate 23 provided at the lower end of the first support rod 22, and a first sealing cover 21 sleeved on the outer wall of the first ring; the first sealing cover 21 is connected to the rotating shaft 13 in a sealed rotation manner, lubricating oil is provided in the first sealing cover 21, and the first support plate 23 is connected to the partition 10. Specifically, the fulcrum of the rotating shaft 13 is mainly on the second support device 30, so the second support device 30 is subjected to greater pressure and is more easily damaged. The first support device 20 and the second support device 30 are only different in position, and their structures are exactly the same.

[0029] The backup support device 40 in this embodiment includes a second bearing 41 sleeved on the outer wall of the rotating shaft 13, a second ring 42 sleeved on the outer wall of the second bearing 41, a second support rod 44 for supporting the second ring 42, a sleeve 45 provided at the lower end of the second support rod 44, a second support plate 46 provided at the lower end of the sleeve 45, side plates 47 provided on both sides of the second support rod 44, and bolts 48 threadedly connected to the side plates 47; the second sealing cover 43 is sealed and rotatably connected to the rotating shaft 13, and lubricating oil is provided in the second sealing cover 43. The lower end of the second support is slidably provided in the sleeve 45, the lower end of the bolt 48 abuts against the second support plate 46, and the second support plate 46 is connected to the partition 10. Specifically, when the backup support device 40 is not in use, the bolt 48 does not contact the second support plate 46, and the lower end of the second support rod 44 does not contact the lower end of the sleeve 45. Therefore, the second bearing 41, the second collar 42, the second sealing cover 43, and the second support rod 44 are suspended, and the backup support device 40 has no supporting effect on the rotating shaft 13. When the second support device 30 (or the first support device 20) is damaged (primarily the bearing is damaged), the bolt 48 can be tightened so that the lower end of the bolt 48 abuts against the second support plate 46. The bolt 48 can also lift the side plate 47, the second support rod 44, the second collar 42, and the second bearing 41, thereby increasing the supporting force of the second bearing 41 on the rotating shaft 13. This can reduce the supporting force of the second support device 30 on the rotating shaft 13, allowing the entire device to continue operating for a period of time.

[0030] In summary, the ball forming machine driving device of the present embodiment, when in use, the motor outputs power to the drive shaft 12 through the reducer 11, and the drive shaft 12 then outputs power to the rotating shaft 13 through the sprocket 14 assembly, and finally drives the ball forming machine to run through the rotating shaft 13. In this way, it is not necessary for the motor, reducer 11, and rotating shaft 13 to be located on the same axis, which can well avoid the eccentric fault caused by the vibration during the operation of the ball forming machine. After the sprocket 14 assembly is changed to drive, the shear force on the end of the rotating shaft 13 becomes larger, so the first device and the second supporting device 30 are set at the end of the rotating shaft 13. The pressure on the second supporting device 30 close to the ball forming machine is greater and more easily damaged. Therefore, when it breaks down, the backup supporting device 40 can be temporarily used to assist in supporting the rotating shaft 13. This can reduce the force on the second supporting device 30, so that the device can continue to run for a period of time, and does not need to be shut down for maintenance immediately. During this time, the production and maintenance process can be reasonably arranged, which can effectively ensure the efficient production.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
