Description

Paper winding device with centered guide function

Technical Field

The utility model belongs to the technical field of printer, duplicator etc., especially, relate to a stock form device of direction placed in middle.

Background

Most thermal-sensitive and thermal transfer printing and other printers at present, the stock form input device of usefulness all adopts a stock form axle and controls two baffles and support spacing stock form, or directly does not have spacing state with a stock form axle, and some complicated operational difficulties of structure, some too simple spacing not enough can not make the stock form steadily placed in the middle, beat the easy incline of printing paper, cause to print the effect not good.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that exists among the above-mentioned prior art, the utility model provides a stock form device of direction placed in the middle, the device convenience of customers installs the stock form, simple structure to can make the stock form steadily placed in the middle, guarantee printing quality.

The technical scheme is as follows:

the roll paper device with the centered guide comprises a roll paper shaft, a paper box assembly and centered guide ribs, wherein the roll paper shaft is installed on the paper box assembly, the upper surface and the lower surface of the roll paper shaft are arc-shaped in a front view, the distance between the two arc-shaped parts on the central axis of the roll paper shaft is shortest, a plurality of centered guide ribs are arranged on the upper surface and/or the lower surface of the roll paper shaft, a central guide rib is arranged on the central axis of the upper surface and/or the lower surface of the roll paper shaft, the centered guide ribs on two sides of the central guide rib are inclined like the central axis by one end of the roll paper outlet side, the inclination angle is α, and 0 degree < α <90 degrees.

Furthermore, the centered guide ribs on two sides of the center guide rib are symmetrical about the central axis.

Further, the paper winding shaft comprises a main shaft and a supporting piece, the two ends of the main shaft are respectively provided with the supporting piece, and the paper winding shaft is detachably connected with the paper box assembly through the supporting piece.

Further, the carton assembly is provided with a notch, and the support member is placed into the notch.

The utility model has the advantages that:

the roll paper device with the centered guide function adopts the arc-shaped roll paper shaft with slightly thin middle and slightly thick two ends, the centered guide rib structure is added on the surface of the roll paper shaft, and roll paper of the thermal-sensitive and thermal-transfer printer rotates automatically centered under the action of the guide rib in the printing state, so that the roll paper is prevented from swinging left and right to influence the normal printing of the printer, and the printing quality is ensured; adopt detachable construction to connect, convenience of customers installs the stock form, simple structure, the cost is lower moreover.

Detailed Description

The centrally directed reel-up is further described below in connection with fig. 1-7.

A centrally-guided paper rolling device comprises a paper rolling shaft 1, a paper box assembly 2 and a centrally-guided rib 3, wherein the paper rolling shaft 1 is installed on the paper box assembly 2, the upper surface and the lower surface of the paper rolling shaft 1 are arc-shaped in a front view, the distance between the two arc-shaped parts on the central axis of the paper rolling shaft 1 is shortest, a plurality of centrally-guided ribs 3 are arranged on the upper surface and/or the lower surface of the paper rolling shaft 1, a central guide rib 31 is arranged on the central axis position of the upper surface and/or the lower surface of the paper rolling shaft 1, one end, close to the outlet side of a paper rolling 4, of the centrally-guided ribs 3 on two sides of the central guide rib 31 inclines like the central axis, the inclination angle is α, 0 degrees < α <90 degrees, and preferably 20 degrees < α.

Further, the central guide ribs 3 on both sides of the central guide rib 31 are symmetrical about the central axis.

Further, the winding shaft 1 comprises a main shaft 11 and a support member 12, the support member 12 is respectively mounted at two ends of the main shaft 11, and the winding shaft 1 is detachably connected with the paper box assembly 2 through the support member 12.

Further, the carton assembly 2 is provided with a slot into which the support member 12 is placed.

As shown in 4, the paper winding device that leads in the middle adopts the arc roll paper axle that the centre is slightly thin, both ends are slightly thick, increases the 3 structures of direction muscle in the middle on 1 upper and lower surfaces of roll paper axle, and the roll paper 4 rotates the automation when the state is printed to the temperature sensing and heat transfer printer and is placed in the middle under the effect of direction muscle 3 placed in the middle, avoids roll paper 4 horizontal hunting to influence the printer and normally prints. This patent convenience of customers installation stock form 4, simple structure can also guarantee that stock form 4 is steady placed in the middle, and the cost is lower moreover.

The working principle is as follows: the roll paper 4 is sleeved on the roll paper shaft 1 and then put on the paper box assembly 2 together, the support piece 12 of the roll paper shaft 1 is placed in a notch on the paper box assembly 2, the roll paper 4 is aligned with a roll paper channel of the printer, and the roll paper 4 is kept in a centered state under the guiding action of the centered guide rib 3 on the roll paper shaft 1 in the printing process, so that the left-right swinging is avoided.

The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
