[0031] The top end of the rake As 6 and the rake Bs 7 is provided with movable rake hooks 9, the hook head side of the rake hooks 9 extends to the outside of the base plates 8.

[0032] The top end of the base plates 8 is provided with holes for inserting steel wires during the base plate rising process.

[0033] The horizontal moving mechanism 3 comprises a horizontal moving rack 31, further comprises a horizontal moving gear 32 matched with the horizontal moving rack 31 and a horizontal moving transmission motor driving the horizontal moving gear 32 to rotate, the horizontal moving rack 31 is fixedly arranged on the cross beam 2.

[0034] ​The end side of the crossbeam 2 is provided with a dovetail groove 21, and the base 1 is provided with a dovetail slider 11 which is slidingly arranged in the interior of the dovetail groove 21.

[0035] The lifting mechanism 4 comprises a plurality of lifting racks 41 which are slidingly arranged on the base 1, the lower end of each lifting rack 41 is fixedly connected with a lifting plate 5, the lifting racks 41 located on the two sides are oppositely arranged, lifting gears 42 are symmetrically arranged between the upper part and the lower part of the lifting racks 41 located on the two sides, and the lifting gears 41 of the upper part are drivingly connected with a lifting transmission motor.

[0036] The rakes A and B correspond to a lifting plate 5 respectively below, the bottom of the rakes A 6 and B 7 respectively acts on the upper side of different lifting plates when moving upward, and the lifting plate 5 has a certain gap with the rakes A 6 and B 7. A plurality of bottom lifting pieces are arranged on the crossbeam, and the bottom lifting piece on at least one side of the front and rear needle plate can be translated and moved up and down through the crossbeam and the lifting plate.

[0037] The bottom lifting pieces 8 are overlapped with each other, and spaces are arranged between the bottom lifting pieces 8.

[0038] The hook tail side of the rake hook 9 is provided with a counterweight 10, and the rake hook 9 and the counterweight 10 are an integral structure.

[0039] The bottom lifting piece 8 is provided with a sliding groove 81 which is slidingly matched with the crossbeam, the position of the bottom lifting piece 8 located at the sliding groove 81 is provided with a thickened plate 82, and the bottom lifting piece 8 and the thickened plate 82 are an integral structure.

[0040] 1. The working principle of the rake hook 9: the lifting mechanism 4 lifts the rakes A 6 or B 7, and in the lifting process, the hook needle exits the fabric because the rake hook 9 is a movable structure. After the rake hook 9 exits the fabric, it continues to be lifted to the required height and stops lifting and then descends. During the descending process, the rake hook 9 will hook into the fabric to complete the lifting piece action under the action of the angle. At this time, the hook body of the rake hook 9 is suspended, and the weight of the hook body is the pulling force to complete the function of the rake hook.

[0041] 2. The working principle of the rake: the rake is divided into the rakes A 6 and B 7, which are mainly used for two rakes to be used alternately. When the rake A 6 rakes upward to weave the fabric, the rake B 7 acts as a gravity rake to straighten the fabric to assist the rake A 6 to smoothly complete the action of raking into the fabric. The two rakes A 6 and B 7 alternately act.

[0042] 3. The working method of the bottom lifting piece: the horizontal moving device 3 moves to the middle to misalign the lifting mechanism 4, and the lifting position of the original rake A 6 moves to the position of the rake B 7. At this time, the lifting position of the original rake B 7 is suspended, and the lifting plate 5 at the position of the rake B 7 can act on the bottom lifting piece 8 when it rises. When the bottom lifting piece 8 rises above the position of the knitting needle plate, it can complete the bottom lifting work by penetrating the steel wire.

[0043] The control method is as follows:

[0044] (1) One lifting transmission motor on the left and right of the front needle bed controls, forward and reverse rotation controls rake A and rake B respectively;

[0045] (2) One lifting transmission motor on the left and right of the back needle bed controls, forward and reverse rotation controls rake A and rake B respectively;

[0046] (3) One horizontal movement transmission motor controls the horizontal movement device, so that the starting sheet 8 is located in the function of the stop weaving sheet and the function of the waste yarn-free starting plate

[0047] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
