Problems solved by technology

[0005] However, in the prior art, the fixed point of the synchronous belt lies in the two pulleys. There are high requirements for the parallelism of the axes of the two pulleys and the flatness of the end faces. The longer the transmission interval, the higher the processing requirements for the base.
Moreover, the loose edge of the synchronous belt only plays the role of force transmission, and the use efficiency is extremely low

Embodiment Construction

[0016] Referring to Fig. 1, in the prior art, the rotation of the pulley generally drives the spray head or print head to perform linear reciprocating motion. In this structure, the motion platform 14 with the print head installed is fixed on the tight side of the conveyor belt 17, and is driven by the drive motor. The reciprocating motion of the motion platform 14 is realized by driving the forward and reverse rotation of the pulley 15 and the pulley 16 .

[0017] Referring to Fig. 2, the printing head drive mechanism of the present invention comprises frame 8 with guide rail 13 and the moving platform 12 that is fixed with printing head, is provided with driving wheel 1, pinching wheel 2 and pinching wheel 3 on the moving platform 12, synchronously The belt 5 partially covers the driving wheel 1 under the limitation of the pressing wheel 2 and the pressing wheel 3, and the two ends of the synchronous belt 5 are fixed on the frame 8, and the driving wheel 1 drives the moving p...

Abstract

The invention discloses a printer head driving mechanism comprising a frame with a guide rail and a movable terrace fixed with the printer head. A driving wheel and two pressing wheels are arranged on the movable terrace. The driving wheel is coated by a synchronous belt under the limit of the two pressing wheels. Both ends of the synchronous belt are fixed on the frame. The movable terrace is driven by the driving wheel and moves along the guide rail under the effect of driving force. The printer head driving mechanism of the invention changes the driving model of the closed synchronous belt of the prior art, and only uses a driving wheel for driving the printer head to carry out reciprocating movement along the single synchronous belt. Besides, tension force of the synchronous belt of the printer head driving mechanism of the invention can be adjusted conveniently.

Description

technical field [0001] The invention relates to a transmission device, in particular to a synchronous transmission mechanism of a printing head. Background technique [0002] Synchronous belts are widely used in transmission systems. There are two traditional synchronous belt transmission methods: one is the transmission of circular motion to circular motion, which is generally used in variable speed motion systems; the other is the transmission of circular motion to linear reciprocating motion. [0003] In the prior art, the nozzles or print heads of inkjet printers and printing machines are all fixed on the tight side of the synchronous belt, and the reciprocating motion is realized by driving the forward and reverse rotation of the pulley by the drive motor. In order to ensure the effective meshing between the synchronous belt and the pulley, it is more common to increase the tension pulley or adjust the center distance between the two pulleys, but the installation of the...
