The present invention relates to a high-speed jacquard, which improves the operation method of the transfer device and the transverse pressurizing plate to cope with the high speed, and improves the driving method to enable fast power transmission and operation. The electric shaft drives the direct jacquard drive shaft, and the hexagonal roller for the paper transfer is changed quickly by using the ratchet device and the operation cam, so that the overall operation and power transmission can be achieved quickly, precisely, and with high speed.

In the conventional jacquard, the power transmission from the electric motor to the jacquard drive shaft is caused by the chain belt, so it has a drawback that the driving speed can not be increased due to the lack of severe vibration. There is no inconvenience to speed up the feed because there is an attempt to change the direction along with the rotating operation by reciprocating the shaker, there was a noisy defect due to the great working noise.

The present invention is intended to correct the above drawbacks, it will be described in more detail based on the accompanying drawings as follows.

The lower end of the lifting rods 20 and 21 of the knife box 22 mounted on the top of the jacquard main body (A) is connected to the lifting operation pieces 16 and 19, and the lower connection piece of the lifting operation pieces is in the horizontal operation section 17. In the jacquard which is driven through the operating rod (10) and connected to the outer connecting shaft (9) of the chain gear (5), the driven bevel gear (3) on the jacquard driving shaft (4) To be engaged with the driving bevel gear 2 of the electric motor 1, and the ratchet gear 25 is attached to the outer end of the rotary shaft rod 24 of the hexagonal roller 23 for rubbing. The support piece 26 is connected, and the connecting pin 27 is attached to the protruding end thereof, the ratchet 28 supporting hole is inserted into the spring 28 ', and the ratchet operation section 29 is installed laterally. The pressure rod 30 is installed between the upper end and the ratchet support piece, and the sliding roller 31 is connected to the other end between the ratchet operations to contact the outer circumference of the rotation line of the actuating cam 33. The contact plate 40 is installed on the inner side of the pressing plate 35 installed on the outside of the lateral fixation plate 45, and both connecting rods 42 are supported by the pressing plate 35 to coil the coil. The spring 43 is elastic, and the sliding roller 36 is provided on both sides so as to be in contact with the outer circumference of the rotation line of the operation cam 34, the guide horizontal bar 37 of the transverse pressure plate 35, the coil spring 38 The transverse needle plate 35 is brought into contact with the working cam, and the rubbing 39 passes between the contact plate 40 and the fixed side plate 45, and the chain gear (outside the operating cam rotating shaft 32) 32 ') is attached to rotate the chain belt 50.

In this way, the bevel gear (3) is installed on the jacquard driving shaft (4) and is directly engaged with the bevel gear (3) of the electric shaft (1). Therefore, the power transmission is quick and accurate during jacquard driving, and the noise is low. The hexagonal roller 23 for feeding the rubbish is equipped with a ratchet gear 25 attached to the outer end of the rotation shaft 24 and engaged with the ratchet 28 of the ratchet support piece 26. Since it is operated by the operation cam 33 of 29), it is rotated at a certain angle, so that accurate rubbing can be carried out. (34) by pressing the lateral needle while reciprocating horizontally at a constant speed, the operation is accurate and quick, and the contact plate 40 is installed on the inner surface of the pressure plate 35 is pressed against the coil spring 43, so the rub pressure is Not only softens, but can also pressurize without shaking, Since the pressure plate 35 falls down first after pressing, the contact plate 40 is successively spaced apart so that there is no risk of damaging the rub even when operated at high speed. This speeds up and speeds up.
