Description

Technical Field

[0001] The utility model belongs to the technical field of paper-molding equipment, and particularly relates to a dual-power balancing connecting rod mechanism. Background Art

[0002] In paper and plastic equipment, such as pulp molding machines and plastic compounding equipment, there are often process steps such as rapid prototyping, molding, and drying, which involve a large amount of reciprocating motion. Furthermore, the single-power balancing linkage mechanism used in paper and plastic equipment is a widely used mechanical transmission method, especially in some high-load equipment that requires balanced torque. The single-power balancing linkage mechanism can effectively reduce machine vibration and improve the stability and lifespan of the equipment. However, the single-power connection structure used in existing paper and plastic equipment has a small force-bearing area, and it is impossible to adjust the angle and motion trajectory of the connecting rod through single power to ensure that the up and down movement of the equipment remains smooth and efficient. As a result, the paper and plastic equipment will experience shaking and imbalance during the reciprocating motion, which will in turn cause mechanical failure due to the imbalance of the reciprocating motion of the paper and plastic equipment.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 The utility model provides a technical solution: a dual-power balancing connecting rod mechanism, comprising:

[0019] A dual-power balancing connector 1 is provided at the bottom of the dual-power balancing connector 1, which is fixedly connected to a balancing mounting base 3 through four movable guide balancing rods 2. The balancing mounting base 3 ensures the balance of the connecting rod system, reduces vibration and mechanical loss caused by power asymmetry or load changes, and maintains the stability and efficiency of the system by supporting and adjusting the motion trajectory of the connecting rod, ensuring that the paper and plastic equipment can operate smoothly and continuously during reciprocating operation. The dual-power balancing connector 1 is movably connected to four balancing connecting plates 4 at the front and rear through pins. The balancing connecting plate 4 is usually used to achieve force balance between different parts in a dual-power system, especially under the action of two power sources of the connecting rod mechanism (such as an electric motor or a hydraulic system), to balance the power output of each part. It helps to adjust the motion state of each connecting rod through the connection with the connecting rod system, ensures uniform power output of the system, and avoids vibration or excessive wear caused by power asymmetry.

[0020] Three upper connecting rods 6 are movably provided between the front and rear balancing connecting plates 4 of the dual-power balancing connecting seat 1 through the middle connecting pin 5. The upper connecting rods 6 and the lower connecting rods 7 are connected to each other and are responsible for transmitting the power source (such as a motor, hydraulic system, etc.) to different components. In a dual-power system, power may come from two different sources. The connecting rod system can ensure that the outputs of these two power sources can work together and be effectively transmitted to the working parts. The bottom ends of the upper connecting rods 6 are movably connected to the movable plate connecting seat 8 through the lower connecting rod 7, ensuring that the movable plate can move smoothly and reliably under the action of the connecting rod mechanism, while ensuring a stable connection to avoid uneven movement due to improper connection. The two ends of the dual-power balancing connecting seat 1 are movably connected to the power connecting rod connecting seat 9 with the power connecting rod 10. The role of the power connecting rod 10 in the dual-power balancing connecting rod mechanism is to achieve power transmission, balance loads, reduce vibration, improve mechanical efficiency and optimize equipment structure. In paper and plastic industry equipment, the reasonable design and use of the power connecting rod 10 helps to ensure the stable operation of the equipment, improve production efficiency and product quality.

[0021] A servo motor 11 is provided with a reduction gear 12 on the output shaft of the servo motor 11, and a power support seat 13 for driving one end of the power connecting rod 10 is provided on the rotating shafts on both sides of the reduction gear 12 to ensure the stability of the power connecting rod 10 during movement. The inner side of the power support seat 13 is movably connected to a power crankshaft 14 that vertically reciprocates the power connecting rod 10 through the rotating shaft of the reduction gear 12, and cooperates with the drive main shaft 17 to ensure the stable operation of the power connecting rod 10.

[0022] The bottom end of the guide balance rod 2 is fixed at the four corners of the end of the balance mounting seat 3, and the guide balance rod 2 is movably connected to the four directions of the end of the dual-power balance connecting seat 1 and extends upward. The middle connecting pin 5 is connected to the inner side of the balance connecting plate 4 arranged in front and behind the dual-power balance connecting seat 1. The upper connecting rod 6 is evenly arranged on the middle connecting pin 5 in front and behind the dual-power balance connecting seat 1. The inner side of the upper end of the upper connecting rod 6 is movably connected to the fixed plate connecting seat 15 through a pin shaft. The lower connecting rod 7 is movably connected to the inner side of the lower end of the upper connecting rod 6 through a pin shaft, and the inner side of the movable plate connecting seat 8 is movably connected to the lower end of the lower connecting rod 7 through a connecting rod connecting pin.

[0023] The power connecting rod connecting seat 9 is installed on both sides of the end of the dual power balance connecting seat 1 and is located on the corresponding outer side of the guide balance rod 2, and the bottom end of the power connecting rod 10 is movably connected to the power connecting rod connecting seat 9 through a connecting rod connecting pin. The front end of the outer side of the reduction gear box 12 is provided with a mounting plate 16 for fixing the reduction gear box 12. A driving main shaft 17 is rotatably provided on both sides of the reduction gear box 12, and the driving main shaft 17 is movably passed through the power support seat 13 and connected to one side of the power crankshaft 14, and the other side of the power support seat 13 is rotatably provided with an auxiliary secondary shaft 18 connected to the other side of the power crankshaft 14.

[0024] Specifically, when in use, the driving main shafts 17 on both sides of the reduction box 12 provide bidirectional power output, so that the servo motor 11 drives the reduction box 12 to rotate, and the reduction box 12 drives the driving main shafts 17 on both sides to rotate, and the driving main shaft 17 uses the power support seat 13 and the auxiliary countershaft 18 to drive the power crankshaft 14 to move in the reduction box 12, and the reduction box 12 uses the driving main shafts 17 at both ends to drive the power crankshaft 14 to rotate, and at the same time the power crankshaft 14 drives the power connecting rod 10 to move, so that the dual power balance connecting seat 1 is vertically moved upward through the guide balance bar 2. The double-power balance connecting seat 1 reciprocates up and down, and the three balance connecting plates 4 set in front and behind the double-power balance connecting seat 1 are driven to move through the middle connecting pin 5. The movement of the balance connecting plate 4 drives the two middle connecting pins 5 to move, and the middle connecting pin 5 drives the upper connecting rod 6 and the lower connecting rod 7 to move through the connecting rod connecting pin. Thus, through the dual power output, the six fulcrums support can achieve a larger force area and more stable operation, thereby realizing the double-sided power output of a single driving spindle 17, making the reciprocating motion of the paper-molding equipment more stable and firm.
