Description

Technical Field

[0001] This utility model relates to the field of hydraulic technology, and in particular to a hydraulic cylinder synchronization device for a baling machine. Background Technology

[0002] In mechanical installation and operation, the use of dual hydraulic cylinders to drive a working device is widespread, ensuring sufficient thrust while generating small angles through the relative movement of the cylinders. However, ensuring the synchronization of the two cylinders when moving in the same direction becomes a major problem in the operation of dual hydraulic cylinder systems. Therefore, researching and developing effective hydraulic cylinder synchronization devices is of great significance for improving the overall performance and reliability of hydraulic systems. Synchronizing multiple cylinders through mechanical transmission mechanisms is commonly used in some simple mechanical equipment. However, this method is limited by the rigidity and precision of the transmission chain and cannot meet the requirements of high precision and high-speed motion. Synchronizing the speed of two hydraulic cylinders in the same direction can be achieved by adjusting the opening size of the speed regulating valve. However, this method has low synchronization accuracy when encountering uneven loads or large load variations, and the installation process results in wasted material and manpower. Therefore, a hydraulic cylinder synchronization device for a baling machine is proposed. Utility Model Content

[0003] This utility model addresses the fact that current equipment or existing technology lacks a suitable device to solve the aforementioned problems, resulting in low synchronization accuracy during use and wasted material and manpower during installation. It provides a hydraulic cylinder synchronization device for a baling machine, effectively achieving synchronized operation of two cylinders, ensuring stable operation of the baling machine, and improving baling effect and quality. The device has a reasonable structural design, facilitates the installation of oil pipes, and is simple to install and maintain, reducing manufacturing and maintenance costs, and effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A hydraulic cylinder synchronization device for a baling machine includes a hydraulic cylinder fixedly connected to the bottom of a frame. The hydraulic cylinder is connected to a hydraulic synchronous motor via a first oil pipe and a second oil pipe. The hydraulic synchronous motor can drive the hydraulic cylinder to work. The hydraulic synchronous motor is fixedly connected to a moving device for adjusting the position. The moving device includes a moving block, which can drive the hydraulic synchronous motor to move.

[0006] The mobile device also includes a housing with a sliding groove. A sliding block is movably installed in the sliding groove. The sliding block is fixedly connected to an adjusting rod. Rotating the adjusting rod can cause the sliding block to move radially. The sliding block is fixedly connected to the moving block. When the sliding block moves, it can drive the hydraulic synchronous motor to move.

[0007] The hydraulic cylinders are symmetrically fixed to the bottom of the frame.

[0008] The first and second oil pipes are connected to the hydraulic synchronous motor and hydraulic cylinder using connectors.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] The use of a hydraulic synchronous motor effectively enables the two cylinders to work synchronously, ensuring stable operation of the baler and improving baling effect and quality. The device has a reasonable structural design, and the movable device facilitates the adjustment of the hydraulic synchronous motor position and the installation of oil pipes. Overall installation and maintenance are simple, reducing manufacturing and maintenance costs. The hydraulic synchronous motor has fewer interfaces and fewer oil pipe connection joints, greatly reducing the possibility of oil leakage and improving the reliability and service life of the device. It is not affected by differences in oil pipe length; even if the first and second oil pipes are of different lengths, the cylinders can still work synchronously, facilitating actual installation.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 The application of dual hydraulic cylinders to drive a working device is very widespread. It can ensure sufficient thrust and generate a small angle through the relative movement of the hydraulic cylinders. However, to ensure the synchronization of the two hydraulic cylinders, four speed control valves 1 are required, and it is not easy to adjust them to a synchronized state. The use of multiple speed control valves 1 in the oil pipe connection process, due to the increase in the number of connection points between the speed control valves 1 and the oil pipe, the increased complexity of the hydraulic system, etc., will lead to an upward trend in the risk of oil leakage in the entire system.

[0018] like Figure 2-4As shown, a hydraulic cylinder synchronization device for a baling machine includes a hydraulic cylinder 2, which is fixedly connected to the bottom of a frame 12. The hydraulic cylinder 2 is connected to a hydraulic synchronous motor 5 via a first oil pipe 3 and a second oil pipe 4. The hydraulic synchronous motor 5 enables the hydraulic cylinder 2 to work. The hydraulic synchronous motor 5 is fixedly connected to a moving device for adjusting the position. The moving device includes a moving block 7, which can drive the hydraulic synchronous motor 5 to move.

[0019] Two hydraulic cylinders 2 are installed at the bottom of the baler frame 12. The two hydraulic cylinders 2 are connected to the oil outlet of a hydraulic synchronous motor 5 via a first oil pipe 3 and a second oil pipe 4, respectively. The oil inlet of the hydraulic synchronous motor 5 is connected to an oil tank (not shown in the figure). When the baler is running, starting the hydraulic synchronous motor 5 allows the two hydraulic cylinders 2 to start working simultaneously. Compared with the previous technique of synchronizing the speed of two hydraulic cylinders by adjusting the opening size of the speed regulating valve 1, using the hydraulic synchronous motor 5 has significant advantages. Firstly, it effectively reduces the risk of oil leakage; secondly, it provides more precise speed adjustment for the hydraulic cylinders 2. Particularly noteworthy is that even if the lengths of the first oil pipe 3 and the second oil pipe 4 are different, it will not affect the simultaneous normal operation of the two hydraulic cylinders 2. This greatly simplifies the actual installation process and avoids inconvenience caused by differences in oil pipe lengths.

[0020] In actual baling machine installation, situations often arise where the two hydraulic hoses are of inconsistent lengths. When connecting these hoses to the hydraulic synchronous motor 5, the hoses may be too long or too short. Excessively long hoses result in waste, while excessively short hoses may be forcefully bent during installation due to distance constraints, affecting their lifespan. To solve this problem, a moving device is fixedly installed at the bottom of the baling machine frame 12, securely connected to the hydraulic synchronous motor 5. During installation, one hose is connected first, and then the position of the hydraulic synchronous motor 5 is adjusted using the moving device. The adjusted position is then measured, and the appropriate length of the second hose is cut. This installation method effectively reduces waste of manpower and resources, significantly improving work efficiency.

[0021] The moving device also includes a housing 9, which has a sliding groove 10. A sliding block 11 is movably installed in the sliding groove 10. The sliding block 11 is fixedly connected to the adjusting rod 8. Rotating the adjusting rod 8 can cause the sliding block 11 to move radially. The sliding block 11 is fixedly connected to the moving block 7. When the sliding block 11 moves, it can drive the hydraulic synchronous motor 5 to move.

[0022] The moving device mainly consists of a housing 9, on which a sliding groove 10 is formed. Inside the sliding groove 10, a sliding block 11 is installed, allowing it to slide smoothly within the groove. A moving block 7 is fixedly connected to the sliding block 11. This moving block 7 is securely connected to the hydraulic synchronous motor 5, thus supporting the hydraulic synchronous motor 5. Adjusting the position of the hydraulic synchronous motor 5 can be achieved via an adjusting rod 8. Operating the adjusting rod 8 pushes or pulls the moving block 7. Since the moving block 7 is connected to the sliding block 11, and the sliding block 11 slides within the sliding groove 10, the moving block 7 can move flexibly under the action of the adjusting rod 8, thereby moving the hydraulic synchronous motor 5, which is fixedly connected to it, to the same position. This structural design greatly facilitates the adjustment of the position of the hydraulic synchronous motor 5 during the installation of the baler when the oil pipe lengths are inconsistent, effectively improving the ease of installation.

[0023] The hydraulic cylinder 2 is symmetrically fixed to the bottom of the frame 12.

[0024] A symmetrical arrangement ensures that the bottom of frame 12 experiences uniform force in all directions when subjected to the force of hydraulic cylinder 2. During operation, the thrust or pull force generated by hydraulic cylinder 2 is evenly distributed across frame 12, preventing excessive localized stress and reducing the risk of deformation or damage to frame 12. In large cargo packaging scenarios, if hydraulic cylinder 2 is asymmetrically arranged, excessive force on one side of frame 12 may lead to frame 12 distortion over time, affecting equipment accuracy and lifespan.

[0025] The first oil pipe 3 and the second oil pipe 4 are connected to the hydraulic synchronous motor 5 and the hydraulic cylinder 2 using a connector.

[0026] When a hydraulic system is working, the hydraulic fluid flows within the pipes and maintains a certain pressure, which the joints must withstand. Fewer joints mean fewer pressure-bearing connection points in the system, thus reducing the likelihood of leaks due to poor sealing. Compared to systems using multiple speed control valves, which require numerous joints to connect the valves and oil pipes, this device only uses joints at the connections between the oil pipes and the hydraulic synchronous motor and hydraulic cylinder, significantly reducing potential leakage points. This effectively lowers the overall risk of leakage in the hydraulic system, ensuring its stability and reliability.

[0027] This utility model provides a hydraulic cylinder synchronization device for a baling machine. The usage process is as follows: Two hydraulic cylinders are symmetrically installed at the bottom of the baling machine frame. The moving device is fixed to the bottom of the baling machine frame, with its moving block fixedly connected to the hydraulic synchronous motor. A first oil pipe, a second oil pipe, and corresponding connectors are prepared. The first oil pipe is first connected to one oil outlet of the hydraulic synchronous motor and one of the hydraulic cylinders via the connector. Using the adjusting rod of the moving device, the moving block is pushed, causing the hydraulic synchronous motor to move to a suitable position. The position data at this point is measured. Based on the measurement results, a second oil pipe of appropriate length is cut, and then connected to the other oil outlet of the hydraulic synchronous motor and another hydraulic cylinder via the connector. The baling machine is started, and the hydraulic synchronous motor is powered on and begins to work. The hydraulic synchronous motor draws hydraulic oil from the oil tank, distributes it equally to the two oil outlets, and enters the two hydraulic cylinders through the first and second oil pipes respectively, pushing the pistons of the hydraulic cylinders to move synchronously, thereby driving the working parts of the baling machine to perform the baling operation. During operation, due to the characteristics of the hydraulic synchronous motor, even if the two oil pipes are of different lengths, the two hydraulic cylinders can still work synchronously. Compared with the traditional speed control valve method, it has a lower risk of oil leakage and more precise speed regulation.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
