Description

Technical Field

[0001] This utility model relates to the field of pelletizing machines, and in particular to a transmission device for a pelletizing machine. Background Technology

[0002] Pelletizers are key equipment used in metallurgy, building materials and other fields to form powdery or small granular materials into pellets with a certain strength and particle size. The transmission device, as a core component, is mainly responsible for power transmission. It needs to transmit the power output from the motor to the pelletizing disc after deceleration and reversal, so as to drive the pelletizing disc to rotate according to the process requirements, so as to ensure the continuity and efficiency of the pellet forming process. It is an important system that determines the overall operating performance of the pelletizer.

[0003] In the application of existing pelletizing machine transmission devices, the motor, reducer and pelletizing disc are usually designed and installed in a direct connection manner. That is, the reducer and the pelletizing machine are at the same angle. After the motor starts, the power is directly transmitted to the reducer installed at the same angle. After the reducer reduces the speed and increases the torque, it directly drives the pelletizing disc to rotate through the transmission shaft. This realizes the transmission of power from the power source to the working parts and meets the operation requirements of the pelletizing disc.

[0004] The existing technology has the following drawbacks: because the reducer is installed at an angle with the pelletizing machine, it cannot maintain a horizontal state, resulting in uneven distribution of oil inside. Key components such as gears and bearings cannot be fully immersed in the reducer oil, making it difficult for the components to obtain sufficient lubrication during high-speed operation. Under long-term operation, the components are prone to serious wear and overheating due to insufficient lubrication, which not only shortens the service life of the reducer but may also cause component damage and failure, leading to the shutdown of the pelletizing machine's transmission device and affecting the overall production progress. Therefore, a transmission device for the pelletizing machine is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a transmission device for a pelletizing machine, which aims to improve the problem of uneven oil distribution in the prior art due to the inclined installation of the reducer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a transmission device for a pelletizing machine, comprising a support frame, a motor fixedly connected to the upper surface of the support frame, a reducer fixedly connected to the upper surface of the support frame, a connecting shaft provided at the output end of the reducer via a universal joint, a pelletizing disc fixedly connected to the right end of the connecting shaft, mounting discs fixedly connected to the side walls of both the motor and the reducer, two sets of mounting discs being provided, a protective cover being detachably installed between the two sets of mounting discs, a connecting pipe fixedly connected to the top of the protective cover, a lubricating bottle detachably installed on the inner wall of the connecting pipe, a guide plate fixedly connected to the inner wall of the top of the protective cover, and an adjustment mechanism provided on the inner wall of the connecting pipe; The adjustment mechanism includes an adjustment screw that is threaded through and connected to the inner wall of the connecting pipe, and a baffle plate is rotatably connected to the end of the adjustment screw.

[0007] As a further description of the above technical solution: The baffle plate is slidably connected to the inner wall of the top end of the connecting pipe.

[0008] As a further description of the above technical solution: The protective cover and the connecting pipe are connected.

[0009] As a further description of the above technical solution: The pelletizing plate is positioned above the load-bearing frame.

[0010] As a further description of the above technical solution: The output end of the motor is located at the connection end of the reducer.

[0011] As a further description of the above technical solution: The output end of the reducer is fixedly connected to one end of the universal joint, and the other end of the universal joint is fixedly connected to the end of the connecting shaft.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by adding a universal joint between the reducer and the pelletizing disc, the horizontal installation of the motor and the reducer is achieved. This solves the problem that the internal parts of the reducer could not be fully immersed in the reducer oil because it was installed at an angle with the pelletizing machine before the improvement. This avoids damage to the parts due to insufficient lubrication, significantly improves the operating stability of the reducer, and extends the service life of the entire transmission device. At the same time, the universal joint can flexibly adapt to changes in the angle of the two shafts, ensuring continuous and stable power transmission from the reducer to the connecting shaft without affecting the normal operation of the pelletizing disc.

[0013] 2. In this utility model, the baffle can be opened by rotating the adjusting screw, so that the lubricating fluid flows through the connecting pipe and the protective cover to the connection between the motor and the reducer. The guide plate design can ensure that the lubricating fluid drips accurately. The operation is simple and efficient. In addition, the sealed connection between the protective cover and the mounting plate can effectively block the connection between the motor and the reducer, prevent impurities and dust from entering, avoid affecting the transmission, and further ensure the reliability of the transmission device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3This utility model provides an embodiment of a transmission device for a pelletizing machine, including a support frame 1. A motor 2 is fixedly connected to the upper surface of the support frame 1. The support frame 1 mainly connects and supports the entire pelletizing disc 6, the motor 2, and the reducer 3. The reducer 3 is fixedly connected to the upper surface of the support frame 1. The reducer 3 uses gear meshing, belt drive, worm gear drive, etc., to reduce the speed of high-speed power sources such as motors and internal combustion engines, while correspondingly increasing the output torque to meet the requirements of various mechanical equipment for appropriate speed and torque. This is prior art and will not be described in detail. The output end of the reducer 3 is connected to a connecting shaft 5 through a universal joint 4. The right end of the connecting shaft 5 is fixedly connected to the pelletizing disc 6. The pelletizing disc 6 is mainly used to form powdery or small granular materials into pellets with a certain strength and particle size. Mounting discs are fixedly connected to the side walls of the motor 2 and the reducer 3. 7. The mounting plate 7 has bolt holes, allowing bolts to pass through the protective cover 8 and connect to the threaded holes of the mounting plate 7. There are two sets of mounting plates 7, and the protective cover 8 is detachably installed between the two sets of mounting plates 7. The contact ends of the protective cover 8 with the mounting plate 7 are made of rubber material, which can increase the sealing between them. The top of the protective cover 8 is fixedly connected to the connecting pipe 9. The inner wall of the connecting pipe 9 is detachably installed with a lubricating bottle 10. The lubricating bottle 10 contains lubricating fluid, which can be used to lubricate the connection between the output shaft of the motor 2 and the reducer 3. The lubricating bottle 10 and the connecting pipe 9 are connected, disassembled, and installed by threads. The top inner wall of the protective cover 8 is fixedly connected to a guide plate 13. The guide plate 13 has an opening in the middle, and the opening has a high-to-low arc, which can allow the lubricating fluid to flow out of the guide plate 13 without accumulating in the guide plate 13. The inner wall of the connecting pipe 9 is provided with an adjustment mechanism.

[0018] The adjustment mechanism includes an adjustment screw 11, which is threaded through and connected to the inner wall of the connecting pipe 9. The connecting pipe 9 has grooves that match the adjustment screw 11, allowing the adjustment screw 11 to move along the grooves. The threads of the connecting pipe 9 and the adjustment screw 11 are sealed using existing sealing technology to ensure that the lubricant does not flow out from the threads. This is a conventional technology. A baffle plate 12 is rotatably connected to the end of the adjustment screw 11. The contact surface between the top of the baffle plate 12 and the inner wall of the top of the connecting pipe 9 is made of rubber material to prevent the lubricant from flowing downwards.

[0019] Reference Figures 3-5 The baffle plate 12 is slidably connected to the inner wall of the top end of the connecting pipe 9. The inner wall of the top end of the connecting pipe 9 has a protrusion, which allows the baffle plate 12 to move to the protrusion position and not to continue moving. The protective cover 8 and the connecting pipe 9 are connected. The inner wall of the protective cover 8 has a groove, which corresponds to the groove at the bottom end of the connecting pipe 9.

[0020] Reference Figures 1-3The ball-forming plate 6 is set above the load-bearing frame 1. The output end of the motor 2 is set at the connection end of the reducer 3. The output end of the reducer 3 is fixedly connected to one end of the universal joint 4. The universal joint 4 is a mechanical transmission component used to connect two shafts with different axes and to reliably transmit power and torque between the two shafts. The other end of the universal joint 4 is fixedly connected to the end of the connecting shaft 5.

[0021] Working principle: First, the entire pelletizing machine transmission device is in its initial state. When motor 2 is started, the output shaft of motor 2 begins to rotate, outputting high-speed rotational power, which is transmitted to the connection end of the reducer 3 connected to it. The output speed of motor 2 is relatively high, and the torque needs to be further adjusted according to the working requirements of the subsequent pelletizing disc 6. Therefore, the reducer 3 is needed to change the speed and torque. The power processed by the reducer 3, together with the universal joint 4, can adapt to the angle change between the two shafts due to its unique structure, and reliably transmits the power output by the reducer 3 to the connecting shaft 5, ensuring that the power transmission is not affected by the angle difference between the two shafts, ensuring the continuity and stability of the transmission, and ensuring the horizontal installation of the reducer 3.

[0022] When lubrication is required at the connection between motor 2 and reducer 3, the adjusting screw 11 can be rotated to move the baffle plate 12 backward along the inner wall of the top of the connecting pipe 9, opening the slot at the bottom of the connecting pipe 9. This allows the lubricant to flow through the connecting pipe 9 and the protective cover 8 into the opening of the guide plate 13. The lubricant then flows through the opening of the guide plate 13 to the connection between motor 2 and reducer 3. After connecting with the mounting plate 7 through the protective cover 8, the connection between motor 2 and reducer 3 is protected by the protective cover 8, preventing impurities and dust from entering the connection and affecting subsequent transmission. When lubrication is not required, simply rotate the adjusting screw 11 in the opposite direction to move the baffle plate 12 forward, using the baffle plate 12 to block the inner wall of the top of the connecting pipe 9. The operation is simple and convenient.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
