Description of reference numerals: the device comprises an unwinding roller 111, a winding roller 112, an expanding roller 113, a supporting vertical plate 114, a reinforcing beam 115, a motor 116, a universal wheel 117, a supporting leg 118, a speed reducer 119 and a connecting plate 120.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples

See fig. 1-3.

The embodiment discloses a winding and unwinding device for a digital printing machine, which comprises a base, an unwinding roller 111, a winding roller 112 and a spreading roller 113 for spreading printing media before winding.

The unwinding roller 111, the winding roller 112 and the expanding roller 113 are all mounted on the base, and in terms of mounting positions, the mounting height of the unwinding roller 111 is higher than that of the winding roller 112, and the mounting height of the winding roller 112 is higher than that of the expanding roller 113. The unwinding roller 111 and the winding roller 112 are both unwound and wound by adopting a driving mode of combining a motor 116 with a speed reducer 119, and the motor 116 and the speed reducer 119 are installed on the side surface of the base.

In this embodiment, under the condition that the installation distance between the unwinding roller 111 and the winding roller 112 does not cause interference between the initial whole printing medium paper tube and the winding roller 112, the unwinding roller 111 and the winding roller 112 are installed compactly as much as possible, so that the volume of the whole winding and unwinding device is reduced, the whole structure is more compact, and the occupied area is reduced.

In this embodiment, the base is arranged in a floor type, and universal wheels 117 and height-adjustable legs 118 are mounted at four corners of the bottom of the base. The universal wheel 117 conveniently receives and releases the removal of rolling up device, when considering being applicable to different digital printing machines, receive unwinding mechanism's height probably need be adjusted, so all install height-adjustable's landing leg 118 in base bottom four corners department in this embodiment, landing leg 118 chooses for use the stand that has the external screw thread, and threaded connection has the nut on the stand, makes it reciprocate and then adjusts the base apart from the distance on ground through revolving the nut soon.

In this embodiment, the base includes two support risers 114, two support risers 114 link together through two reinforcing beam 115, the welding of reinforcing beam 115's both ends has connecting plate 120, connecting plate 120 and support riser 114 pass through bolted connection, connecting plate 120 is the rectangular steel sheet, reinforcing beam 115's tip welding is in connecting plate 120 the position or the position of leaning on down by, link together through setting up connecting plate 120 messenger reinforcing beam 115 and support riser 114, can increase this receipts unwinding device's antitorque nature and stability.

In this embodiment, the spreader roll 113 is a double-opening brush roll. Two divisions of brush rollers are installed soft brush on referring to the roller, and the brush leans out the installation with certain angle respectively with it of roller intermediate position, because the brush is to the slope installation of both sides, consequently the brush roller rotates the in-process and all the time with print media to both sides exhibition flat, has certain expanding, exhibition wrinkle effect, and on the other hand still has certain clean effect.

In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention.
