All the electromagnetic valves are controlled by a PLC controller.

The power of the structure is transmitted to four eccentric wheels through bevel gears by a main shaft, the four eccentric wheels drive a left upper palm plate force arm 12, a right upper palm plate force arm 1201, a left lower palm plate force arm 21 and a right lower palm plate force arm 2101 to swing up and down, when the eccentric wheels rotate to the lowest point, the left upper palm plate force arm 12, the right upper palm plate force arm 1201, the left lower palm plate force arm 21 and the right lower palm plate force arm 2101 rotate to the highest point (namely, an upper dead point), and when the eccentric wheels rotate to the highest point, the left upper palm plate force arm 12, the right upper palm plate force arm 1201, the left lower palm plate force arm 21 and the right lower palm plate force arm 2101 rotate to the lowest point (namely, a lower dead point).

The upper left palm plate force arm 12 and the upper right palm plate force arm 1201 control the rising and high position keeping of the first heald plate 5 and the second heald plate 501; the lower left lower palm plate force arm 21 and the right lower palm plate force arm 2101 control the descending and low-position keeping of the left lower palm plate force arm 21 and the right lower palm plate force arm 2101, namely the left upper palm plate force arm 12 and the right upper palm plate force arm 1201 ascend to enable the first heddle plate 5 and the second heddle plate 501 to ascend, the lower left lower palm plate force arm 21 and the right lower palm plate force arm 2101 ascend to enable the first heddle plate 5 and the second heddle plate 501 to descend, and therefore the left upper palm plate force arm 12 of the same heddle plate cannot ascend simultaneously. The upper left palm plate force arm 12 is controlled by an upper left parallel hook 13; the upper left palm plate force arm 12 will remain stopped at the highest point (as shown in fig. 3) only if both hooks of the upper left parallel hook 13 are selected to be hooked; under the condition that the first left selecting hook 14 and the second selecting hook 16 hook the upper left parallel hook 13, the upper left palm plate force arm 12 can push the palm plate to continuously rise and release; the first left selecting hook 14 and the second selecting hook 16 must be accurately moved and must be moved with a gap at the upper and lower dead positions.

The left upper palm plate force arm 12, the right upper palm plate force arm 1201, the left lower palm plate force arm 21 and the right lower palm plate force arm 2101 are respectively swung to a bottom dead center, the lower ends of the third selecting hook 17 and the fourth selecting hook 19 are pressed to a left lower parallel hook 20, and hooked hooks can be released; and the upper end of the arm 12 of the upper left palm plate is separated, at the moment, the upper selecting hook of the upper left parallel hook 13 cannot be separated, and the third selecting hook 17 cannot hook the lower left parallel hook 20. Therefore, only the upper left palm plate force arm 12 can be moved at the top dead center, and only the lower left palm plate force arm 21 can be moved at the bottom dead center. And only when the first heald plate 5 does reciprocating swing between the upper dead point and the lower dead point, the left upper palm plate force arm 12 can be driven to ascend or the left lower palm plate force arm 21 can be driven to descend, so that the ascending or descending of the first heald plate 5 is controlled.

The main shaft is connected with a motor, the motor drives the main shaft to rotate, A, B two pulse signals are taken from a certain proper position of the main shaft, and whether the main shaft rotates forwards or backwards can be judged according to the sequence of A, B two pulse signals; if the A phase pulse is ON and the B phase pulse is turned from OFF to ON (rising edge), the counting is positively increased; if the A phase pulse is ON, the B phase pulse is turned from ON to OFF (falling edge), the counting is reversed and reduced; therefore, the automatic bidirectional counting of whether the woven pattern is the step number or the step number is reduced is realized, and whether the counting accuracy directly influences the result of indexing output. Two signals X75 and X74 of an upper dead point and a lower dead point are taken from the halter, a signal X7 is taken from the position of the eccentric wheel just after the eccentric wheel reaches the dead point, and then a signal X17 is taken from the position of the eccentric wheel about to leave the dead point, wherein the two signals X7 and X17 are used as a heald comparison signal and an electromagnetic valve output signal; these six position signals are important conditions to ensure that the solenoid valve is tightly controlled. The two position signals of the heald (the first heald 5 and the second heald 501) and the shuttle are mainly used for detecting whether the loom operates according to a preset program or not and play a role in detecting error shutdown.

When the main shaft rotates forwards, firstly, signals of upper dead point and lower dead point are sent, then an X7 heald plate comparison signal is sent, the in-place condition of the first heald plate 5 is compared with the position of the second heald plate 501 required by a program, if the results are different, the first heald plate 5 is considered to have an error and is stopped immediately, if the results are the same, the operation is continued, the shuttle beating and the weft insertion are carried out once, after the weft insertion is finished, the program of A, B signals is added by one step, finally, an X17 signal is sent, and palm lifting data (indicating electromagnetic valve action data) of the second heald plate 501 in the next step are output. When the signal is inverted, X17 is used as a heald comparison signal, and X7 is used as an output signal. The purpose of the treatment is that the alarm is immediately stopped when the opening of the first palm plate 5 in the previous step is not completed correctly, the next weft insertion is forbidden, the error of pattern is prevented, if the opening of the first palm plate 5 in the previous step is normal, the next weft insertion is completed normally, the winding device is driven to wind the carpet through the mechanical gear after the weft insertion is completed, the yarn feeding roller is driven to rotate to feed yarn when the tension of the warp yarn is large to a set value, and the yarn feeding is stopped when the tension of the warp yarn is less than the set value, so that the machine can finish the weaving of the carpet in one step according to the action sequence of the opening, the weft insertion, the winding and the yarn feeding.

The present invention is not limited to the above preferred embodiments, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
