The existing opening device has the following defects:
1. the distance between the connecting rod sheets is small (only 1mm of gap exists between the sheets), once the connecting rod deforms due to repeated friction, the deformation of the connecting rod is aggravated, the running resistance is increased, and even open fire and other fatal hazards can be caused;
2. in the process of driving the heald frame to rapidly rise, the dead weight of the heald frame and accessories hung on the heald frame is always completely overcome, so that the torque greatly rises;

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, but the present invention is not limited to these examples.
As shown in fig. 1, the energy-saving electronic shedding device comprises a frame, wherein a plurality of heald frames are arranged on the frame. An energy-saving balancing device is arranged above each heald frame, and a shedding device is arranged below each heald frame.
Each of the heald frames comprises an upper beam 1 and a lower beam 2 which are connected to each other. The energy-saving balancing device is positioned above the upper beam 1, two ends of the upper beam 1 are respectively connected with the energy-saving balancing device, and after the upper beam 1 is connected with the energy-saving balancing device, the energy-saving balancing device enables the upper beam and the lower beam to hover at the opening balancing position without external force.
Specifically, the energy-saving balancing device comprises a left fixed pulley 3, a left connecting rope 4, a right fixed pulley 7, a right connecting rope 6 and an elastic connecting piece 5 for connecting the left and right connecting ropes. The left end of connecting rope 4 on the left side is walked around link to each other with the left end of entablature 1 behind the left side fixed pulley 3, and the right-hand member of connecting rope 4 on the left side passes through elastic connection spare 5 links to each other with the left end of right side connection rope 6, and the right-hand member of right side connection rope 6 is walked around link to each other with the right-hand member of entablature 1 behind the right side fixed pulley 7. The pre-elongated tension of the elastic connecting piece 5 causes the upper and lower beams to hover at the opening balance position.
Of course, the energy-saving balancing device in the invention is not limited to the combination form of the fixed pulley, the connecting rope and the elastic connecting piece, any deformation form which can realize that no external drive is always generated in the motion process of the heald frame, the gravity of the heald frame and the accessories thereof is similar, and the force which is always opposite to the gravity of the heald frame and the accessory thereof is the same or similar can meet the requirement.
Preferably, the elastic connection member 5 is a tension spring. When the heald frame is in operation, the starting position of the heald frame is a position where the tension of the tension spring is equal to the gravity of the heald frame and the accessories thereof so as to keep the heald frame balanced. For example, the spring force coefficient of the tension spring is about 0.1N/MM, and when the heald frame moves up and down, the maximum value of the change in the tension on both sides is 2 × 75 × 0.1 — 15N according to hooke's law in a range where the heald frame moves up and down to the upper and lower limits (the shedding motion limit range ± 75 MM). Because the gravity of the heald frame and the accessories thereof is constant, the change of the tension in the limit range of the vertical movement of the heald frame is less than or equal to 15N, and the starting position is the balance position, the tension of the energy-saving balancing device in the limit range of the vertical movement of the heald frame is approximately equal to the gravity of the heald frame and the accessories thereof. In the whole driving process, the energy-saving balancing device not only changes the property of the load, but also reduces the size of the driving force and the energy consumption.
Of course, the elastic connecting element 5 of the present invention is not limited to the tension spring, and any other type of elastic element can be used as long as it can ensure the tension force to keep balance with the self-weight of the heald frame and its accessories.
The opening device is located below the lower beams 2, two ends of each lower beam 2 are respectively connected with the opening device, and the opening devices are driven to move up and down regularly to form an opening.

The rotary motion of the output shaft of the servo motor 9 is converted into synchronous reciprocating lifting motion of a left vertical rod 15 and a right vertical rod 19 through the transmission of the gear transmission assembly, the left coupler 12, the right coupler 16, the left swing rod 13, the right swing rod 17, the left connecting rod 14 and the right connecting rod 18, and the lifting motion of the upper beam and the lower beam is driven to form an opening. The left side and the right side of the rack are respectively provided with a guide sleeve 8 matched with the upper beam and the lower beam, and the upper beam and the lower beam move along the guide sleeves 8 in the up-and-down movement process.
Of course, the structure for transmitting the power of the servo motor in the invention is not limited to the above structure, and any structure capable of converting the rotation motion of the output shaft of the servo motor 9 into the lifting reciprocating motion of the vertical rods at both sides and driving the up and down opening of the heald frame can meet the requirement.
In the whole power transmission process, the opening devices below two adjacent heald frames are independent, the gear shaft interval of each driven gear 11 is fixed, the intervals among the swing rods, the connecting rods and the vertical rods are large, the driven gears are located in different three-dimensional spaces, and the safety problems of mutual friction and dryness do not exist, so that potential safety hazards are eliminated.
