Detailed Description

In order to solve the problem that the unwinding mechanism cannot prevent the unwinding roller from rotating in the opposite direction to cause the unwinding mechanism to stop the canvas from rotating in the opposite direction to collect the canvas which is printed when the unwinding equipment stops running, the canvas printing unwinding mechanism is particularly provided. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Please refer to fig. 1-3, the embodiment provides a canvas printing unwinding mechanism, which includes an unwinding plate 1, an unwinding frame 2 fixedly installed on one side of the surface of the unwinding plate 1, an unwinding roller 3 rotatably installed in the middle of the surface of the unwinding frame 2, a canvas body rotatably installed on the surface of the unwinding roller 3, and an installation frame 5 fixedly connected to one side of the surface of the unwinding frame 2.

In order to prevent the unwinding roller 3 from rotating in the opposite direction when the unwinding roller stops, the surface of the mounting frame 5 is fixedly provided with the rotating motor 4, the inner cavity of the unwinding frame 2 is provided with the fluted disc 31, the top of the inner cavity of the unwinding frame 2 is fixedly provided with the fixing plate 7, the bottom of the fixing plate 7 is provided with the limiting plate 73, a connecting shaft 74 is arranged between the fixing plate 7 and the limiting plate 73, and the bottom of the fixing plate 7 is fixedly provided with the extending block 71.

The inner cavity of the extension block 71 is provided with a rotation groove 72, the limiting plate 73 is rotatably installed in the inner cavity of the rotation groove 72 through a connecting shaft 74, one end surface of the limiting plate 73 is attached to the surface of the inner cavity of the rotation groove 72, the bottom of the limiting plate 73 is attached to the surface of the fluted disc 31, when the rotating motor 4 normally operates, the limiting plate 73 rotates in the rotation groove 72 through the connecting shaft 74, and meanwhile, due to the arrangement of the rotation groove 72 and the connecting shaft 74, the limiting plate 73 does not influence the normal operation of the fluted disc 31 and the unwinding roller 3

When the rotating motor 4 stops operating, the surface of one end of the limiting plate 73 is attached to the inner cavity of the rotating groove 72, so that the limiting plate 73 cannot rotate in the reverse direction, and the bottom of the limiting plate 73 is attached to the surface of the toothed disc 31, so that the toothed disc 31 is limited from rotating in the reverse direction when rotating in the reverse direction, and the unwinding roller 3 is effectively prevented from rotating in the reverse direction when stopping operating.

Further prevent to unreel 3 and rotate motor 4 synchronous rotation with driving fluted disc 31 in the opposite direction rotation, prevent to rotate motor 4 and burn out because of the opposite direction rotation, reduce economic loss, can prevent to unreel 3 opposite direction rotation of roller and influence unreeling of roller 3 surface canvas simultaneously.

In order to conveniently unreel the canvas by the unreeling roller 3, the surface of one end of the unreeling roller 3 penetrates through the middle part of the unreeling frame 2 and the fluted disc 31, the output shaft of the rotating motor 4 penetrates through the middle part of the unreeling frame 2 and the fluted disc 31, the rotating motor 4 rotates to enable the fluted disc 31 fixedly connected with the output shaft of the rotating motor 4 and the unreeling roller 3 to synchronously rotate, and the rotation of the unreeling roller 3 can conveniently realize the unreeling process of the canvas on the surface of the unreeling roller 3.

Example 2

Referring to fig. 1-3, a further improvement is made in example 1:

in order to make things convenient for the better entering lithography apparatus of the canvas of difference in height, unreel 2 surperficial both sides slidable mounting of frame and have regulating plate 6, unreel 2 surperficial both sides of frame and seted up with regulating plate 6 assorted adjusting groove 61, because the canvas reduces at the in-process that unreels gradually for the height when unreeling 3 surperficial canvas of roller gets into lithography apparatus changes, leads to the canvas to get into the difference in height in the lithography apparatus under too much or too little circumstances.

The canvas gets into the unable matching of in-process height of lithography apparatus and influences the printing process of lithography apparatus to the canvas, and regulating plate 6 slides at regulating groove 61 inner chamber and makes 6 bottoms of regulating plate highly adjust the canvas that gets into 3 surfaces of unreeling roller for height when too much or too little canvas gets into lithography apparatus is unanimous all the time, thereby can make things convenient for lithography apparatus to print 3 surface canvases of unreeling roller more.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
