The end of the heating net 41 is fixed with a rectangular slider in threaded connection with a screw 44 through a screw, the slider is connected with a guide rail 43 in a sliding manner, the screw 44 is vertical to the cloth surface, and the screw 44, the slider and the guide rail 43 are in one-to-one correspondence.

The stepping motor 45 is fixed to the drying rack 11 by screws, and an output shaft thereof is coaxially fixed to the screw 44, thereby driving the screw 44 to rotate. The one end coaxial fixed with drive wheel 441 that drying rack 11 was kept away from to screw rod 44, the cover is equipped with drive belt 442 on two drive wheels 441, drive the drive wheel 441 of cloth both sides in step through drive belt 442 to this drives screw rod 44 synchronous rotation, reduces step motor 45's use amount, and reduce cost reduces the interval error of heating net 41 both ends and cloth simultaneously, improves the even degree of heating net 41 to the cloth heating.

The last cladding of heating net 41 has casing 411, and casing 411 passes through the fix with screw with heating net 41 to this isolated heating net 41 and external, can dismantle on the casing 411 and be connected with filter screen 42, and casing 411 leans on one side opening setting of cloth, has seted up spout 461 on the both ends inner wall of casing 411. The bottom end of the sliding slot 461 is closed, the top opening is upward, and the two ends of the filter screen 42 are in inserting fit with the sliding slot 461. Impurities such as woolen yarns are adhered to the cloth, and the contact between the woolen yarns and the heating net 41 is avoided through the filter screen 42, so that the peculiar smell caused by burning of the woolen yarns is avoided, and meanwhile, the service life of the heating net 41 is prolonged.

The implementation principle of the embodiment is as follows: before printing, an operator only needs to slide the sliding sleeve 263 to enable the distance between the two infrared sensors 262 to be consistent with the width of the cloth, and the infrared sensors 262 are centered according to the measuring scale 265, so that the deviation of the cloth can be conveniently detected, and the sliding base 22 can be corrected.

The transfer roller 121 is driven by a driving motor 122 to transfer the cloth to the head 13 for ink ejection. During ink jetting, the infrared sensor 262 detects the deviation of the cloth, when the cloth deviates to one side, the infrared sensor 262 is triggered and an electric signal is sent to the controller 267, and the controller 267 controls the transmission motor 251 to be started to enable the stud 24 to rotate. At this time, the slide 22 moves to the triggered infrared sensor 262 side, so as to finely adjust the position of the slide 22, so that the position of the slide 22 corresponds to the position of the cloth all the time, the ink-jet position of the head 13 corresponds to the position of the surface of the cloth, the printing accuracy is improved, and the printing quality is improved. The head 13 and the slide 22 are driven to move relatively by the oil cylinder 23, so that the head 13 is controlled to jet ink on all positions of the surface of the cloth, and patterns of various colors are formed.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
