Detailed Description

The present invention will be further described with reference to specific embodiments, illustrative embodiments and description of which are provided herein to explain the present invention, but not to limit the present invention.

Example 1

The utility model provides a four-color press printing is with paper feed mechanism, as shown in figure 1, including framework 1, guide bar 2, spring 3, paper feed wheel 4, motor 5, tray 6 and flourishing board 7, the framework 1 left and right sides is provided with a guide bar 2, the quantity of guide bar 2 is four, the upper end of guide bar 2 is slidingtype and is connected with a flourishing board 7, 2 outside covers of guide bar are equipped with spring 3, the one end and the flourishing board 7 rigid coupling of spring 3, the other end of spring 3 then is fixed with framework 1 bottom and is connected, framework 1 upper portion is provided with a paper feed wheel 4, framework 1 right side is provided with a tray 6, be provided with a motor 5 on the tray 6, the output shaft and the paper feed wheel 4 of motor 5 are fixed and are connected.

When using this device, at first need will only hold board 7 and push down, spring 3 shrink this moment, will print paper later place on holding board 7 can, spring 3 resets afterwards, and spring 3 can produce an ascending power to holding board 7 for the last printing paper of holding board 7 is hugged closely paper feed wheel 4, and behind the starter motor 5, paper feed wheel 4 can drive printing paper and carry out the paper feed, reaches the effect of automatic paper feed.
