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.

See, for example, fig. 1-3.

The embodiment discloses a winding and unwinding machine with a front winding brush roller for a digital printing machine, which is particularly suitable for the digital printing machine with a printing medium being transfer paper, so that the following description is provided by taking the transfer paper as the printing medium.

The winding and unwinding machine with the front winding and unwinding brush roller comprises a base 1, an unwinding roller 2, a winding roller 3, a front winding brush roller 4, a first speed reducing motor 6, a second speed reducing motor 7 and an expanding brush roller 8.

In this embodiment, the base 1 includes two side wall boards 100 and a plurality of crossbeams 101 connected between two side wall boards 100, and a universal wheel 102 and a supporting leg cup 103 are all installed to the both ends bottom of every side wall board 100, and this receipts unreeling machine is conveniently removed to the universal wheel 102, and when the installation ground unevenness, the accessible is adjusted supporting leg cup 103 and is made this receipts unreeling machine be in a steady state.

In this embodiment, unreel roller 2 and wind-up roll 3 and install between both sides wallboard 100 parallelly, and all rotate with wallboard 100 and be connected, unreel roller 2 and be located the oblique top position of wind-up roll 3, satisfy the installation distance between unreeling roller 2 and the wind-up roll 3 and can not make under the condition that the most initial whole printing medium fiber container produced the interference with wind-up roll 3, will unreel roller 2 and wind-up roll 3 compact installation as far as possible, and then make whole receipts and unreel the organism volume reduction, whole structure is compacter, and the floor space is reduced.

In this embodiment, unwinding roller 2 is driven by gear motor one 6, and winding roller 3 is driven by gear motor two 7, and gear motor one 6 and gear motor two 7 are installed in one of them side wall 100 outside.

In this embodiment, the pre-winding brush roller 4 is used for cooperating with the winding roller 3, applying pressure to the transfer paper before winding, and expanding and flattening the transfer paper, specifically, two rotating arms 5 in a V shape are required to be arranged for mounting the pre-winding brush roller 4, the two rotating arms 5 are respectively located at two ends of the pre-winding brush roller 4, two support plates 104 are symmetrically mounted on the inner sides of the two side wall plates 100, one end of each rotating arm 5 is rotatably connected with the support plate 104, the other end of each rotating arm 5 is rotatably connected with the end of the pre-winding brush roller 4, and the rotation connection point of the rotating arm 5 and the support plate 104 is located right above the rotation connection point of the winding roller 3 and the base 1.

In this embodiment, the spreading brush roller 8 is disposed downstream of the wind-up roller 3, and is rotatably connected to the side wall panels 100. The expanding brush roller 8 and the rolling front brush roller 4 both adopt double-opening brush rollers. 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. The concrete structure refers to the prior art.

In this embodiment, the reel-shaped blank transfer paper on the unreeling roller 2 enters the printing part of the digital printing machine for printing after unreeling and unfolding, and then is sent to the reeling roller 3 through a series of conveying rollers, the reeling process is firstly performed with spreading and flattening and wrinkle removal through the spreading brush roller 8, and then the spreading and flattening and wrinkle removal are performed again through the front rolling brush roller 4 before being reeled by the reeling roller 3, and the front rolling brush roller 4 can apply certain pressure to the transfer paper to ensure that the reeling is compact. As the thickness of the roll-shaped printed transfer paper on the wind-up roller 3 gradually increases, the pre-wind brush roller 4 rotates together with the rotating arm 5 about the hinge point of the rotating arm 5 and the support plate 104 and is lifted upward, and during this process, the pre-wind brush roller 4 is always in contact with the side of the transfer paper without printing, and provides pressing force to the transfer paper.

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. All the foundation the utility model discloses an all include in the protection scope of the utility model discloses an equivalent change or simple change that structure, characteristic and principle do. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
