The second gear set 32 can reduce the speed of the first servo motor and then transmit the transmission to the let-off roll 33, the first tension sensor on the let-off roll 33 can detect the tension of the warp 70 and transmit the tension information to the controller, and the second driver 31 is controlled to adjust the rotating speed through the calculation of the controller so as to adjust the rotating speed of the let-off mechanism 30.

Referring to fig. 1, as a specific implementation manner of the silk screen weaving device according to the second embodiment of the present invention, the winding mechanism 60 further includes a winding roller 63 and a third gear set 62 connected to one end of the winding roller 63, and the third gear set 62 is connected to an extending end of a fifth driver 61 disposed on the frame body 10; the take-up roll 63 is provided with a second tension sensor for detecting the tension of the warp thread 70 between the let-off mechanism 30 and the take-up mechanism 60, and the second tension sensor is electrically connected with the controller. The second tension sensor on the take-up roll 63 can detect the transmitted tension of the warp threads 70 and transmit the tension information to the controller, and the controller controls the fifth driver 61 to rotate so as to ensure that the tension of the warp threads 70 between the warp feeding mechanism 30 and the take-up mechanism 60 is constant, and further the quality of products is improved.

Referring to fig. 10, as a specific implementation manner of the silk screen weaving device according to the second embodiment of the present invention, the rapier-inserting and weft-inserting mechanism 50 further includes a rapier band 53 for pulling the weft thread to pass through the warp thread 70 and a gear 52 engaged with the rapier band 53, and the gear 52 is connected to an extending end of the third driver 51. The rapier tape 53 is made of elastic material, and the side surface of the rapier tape 53 is provided with a tooth hole meshed with the gear 52, the rotary motion of the third driver 51 is changed into the reciprocating motion of the rapier tape 53 by the meshed connection relationship, the structure is simple, and the practicability is high.

Referring to fig. 9, in a time chart of the silk screen weaving device according to the second embodiment of the present invention, in a period t, the sword starts to start from 80 degrees to 90 degrees in 0.01 second when used, reaches the limit position from 90 degrees to 225 degrees in 0.19 second when used, starts to return from 225 degrees to 300 degrees, reaches the return intersection point with the sword belt 53, takes 0.007 second, returns to the start point from 300 degrees to 360 degrees in 0.01 second when used, and the sword belt 53 completes a reciprocating displacement and pulls the weft once. The moving speed and the period of the rapier tape 53 are controlled within the beating-up intermittent period, in addition, the rapier tape 53 only does reciprocating motion and does not swing along with the steel buckle 45, and the static rapier throwing mode is adopted, so that the operation stability of the device is improved, and meanwhile, the weft insertion speed is also improved. In addition, the sword throwing process has no interference with beating-up work, and the actual use effect is good.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
