Abstract
The utility model discloses a tightening-feeding device of printing media, comprising a cloth-feeding roller, a guiding roller. The cloth-feeding roller is driven by a gear box actuated by a motor. The utility model is characterized in that the gear box used to drive the cloth-feeding roller to rotate is simultaneously in transmitting connection with the guiding roller via a transmission device, wherein the transmission device enables the rotating linear speed of the guiding roller to be excessive than that of the cloth-feeding device. By employing the tightening-feeding device of printing media of the utility model, because the guiding roller also rotates actively, the rotating linear speed of the guiding roller is slightly excessive than that of the cloth-feeding device, and friction exists between the printing media and the guiding roller, thereby certain tension of the printing media during the process of feeding is always kept in rotation of the cloth-feeding roller, and further realizing level feeding of the print media.
Description
Technical field
The utility model relates to the air brushing machine, relates in particular to the air brushing medium tensioning feed mechanism of air brushing machine.
Background technology
The air brushing medium feed mechanism of existing air brushing machine comprises feed preparation unit roller and guide roller, the air brushing medium is by sending the step roller when delivering to guide roller, air brushing drawing in the air brushing medium of printhead between feed preparation unit roller and guide roller, because guide roller itself is unpowered, be by frictional force and drive and passive rotation with the air brushing medium, the air brushing medium only by feed preparation unit roller at the uniform velocity stepping send to, this causes the air brushing medium rough phenomenon to occur easily, influences the air brushing image quality.
Summary of the invention
The utility model provides a kind of air brushing medium tensioning feed mechanism, and it can avoid the air brushing medium rough phenomenon to occur in sending process to.
Air brushing medium tensioning feed mechanism described in the utility model, comprise feed preparation unit roller, guide roller, feed preparation unit roller be is characterized in that by the gearbox transmission of driven by motor: drive gearbox that feed preparation unit roller rotates and also be in transmission connection by the transmission mechanism and the guide roller of a rotational line speed that makes guide roller a little more than the rotational line speed of feed preparation unit roller simultaneously.
But above-mentioned transmission mechanism chain-wheel mechanism, transmission mechanisms such as gear drive, synchronous band, belt.
Adopt air brushing medium tensioning feed mechanism described in the utility model, because guide roller is active rotation also, and its rotational line speed is a little more than the rotational line speed of feed preparation unit roller, and have frictional force between air brushing medium and the guide roller, so make the air brushing medium in sending process to, remain certain tensile force during the fabric guide roll rotation, send to thereby reach the smooth of air brushing medium.
Description of drawings
Fig. 1 air brushing medium described in the utility model tensioning feed mechanism structural representation.
The specific embodiment
As shown in Figure 1,1 is that air brushing medium, 2 is that feed preparation unit roller, 3 is that gearbox, 4 is that sprocket wheel, 5 is that chain, 6 is that flywheel, 7 is a guide roller.
Feed preparation unit roller 2 is by gearbox 3 driven rotary, and guide roller is by a chain-wheel mechanism transmission, this chain-wheel mechanism comprises sprocket wheel 4, chain 5 and flywheel 6, sprocket wheel 4 is installed on the output shaft of gearbox 3, flywheel 6 is installed in the axle head of guide roller, the transmission of torque of the gearbox that will link to each other with feed preparation unit roller 2 by certain speed ratio by chain 5 to guide roller 7, the linear velocity that the rotational line speed of guide roller 7 is rotated a little more than feed preparation unit roller 2.
Claims (3)
