Abstract

The utility model relates a paper feeding mechanism with guide limit function, especially suitable for printing devices with coiled paper as printing carriers such as printing calculator and cashing printer in supermarkets. The printing device's paper feeding guide mechanism is special in that it includes an upper cover and lower cover, which form an empty chamber. One of the covers is set with paper inlet, and the chamber is set with paper feeding guide groove. The paper feeding mechanism can feed printing paper smoothly from paper inlet guide to the printing place. The paper feeding mechanism also has the function of restricting the level movement of printing paper so as to avoid printing deviation.

Description

A kind of paper feed guiding mechanism of printing equipment

Technical field

The utility model relates to a kind of paper feed guiding mechanism of printing equipment, particularly utilizes the paper feed guiding mechanism on the printing calculator.

Background technology

Chinese patent CN2334053Y discloses a kind of printing computer, wherein prints coil paper and is hidden in the calculator, by rotation pivot paper is sent into the printing paper feed port, wherein prints in the paper feed process not impose any restrictions entering paper.Therefore in actual printing operation process toward the ill phenomenon of paper feed back occurring, the phenomenon that may occur the dislocation of paper feed and printing portion sometimes, when particularly changing coil paper, the paper of packing into from paper feed port need be sought the paper feed of printing portion, this process all needs manually to finish, so often make troubles, be not easy to operation.In printing the paper feed process, also the phenomenon of horizontal shift may occur in addition, thereby cause the phenomenon of printing skew.

The utility model content

The purpose of this utility model is to overcome the problems referred to above, has proposed a kind of paper feed mechanism with guide and limit function, is specially adapted to printing calculator, supermarket cash register printer etc. and adopts in the printing equipment of coil paper band as print carrier.

The purpose of this utility model can reach by following measure:

The paper feed guiding mechanism of this printing equipment, its special character is: described paper feed guiding mechanism comprises loam cake and lower cover, and loam cake and lower cover form a cavity, and one of them covers and is provided with paper feed port; Described cavity inside is provided with the paper feed gathering sill.

The purpose of this utility model can also reach by following measure:

Described paper feed gathering sill is formed by the drum position that the arc that is fixed on the upper and lower covers inboard matches each other.

The drum position that covers on described has the curved surface to the lower cover projection, wherein fixes near an end of paper feed port, and described lower cover has the concave curvatures that is complementary with above-mentioned drum position, and upper and lower covers combination back forms the paper feed gathering sill.

The drum position that has convex surface in the described arc drum position is single tongue type, and the drum position with concave surface is many tongues type.

Be provided with the drum position that the restriction paper perpendicular to paper feed port moves horizontally in the described upper and lower covers cavity.

The utility model has following advantage compared to existing technology:

1, it is smooth and easy that this paper feed mechanism makes the print paper paper feed, automatically paper tape is directed to printing from paper feed port.

2, this paper feed mechanism also has the function that the restriction print paper moves horizontally, the generation that can avoid printing shift phenomenon.

Description of drawings

Fig. 1 is the paper feed guiding mechanism loam cake partial schematic diagram of described printing equipment.

Fig. 2 be among Fig. 1 A-A to cutaway view.

Fig. 3 is the paper feed guiding mechanism lower cover partial schematic diagram of described printing equipment.

Fig. 4 be among Fig. 2 B-B to cutaway view.

Fig. 5 is a upper and lower covers assembly partial schematic diagram.

The specific embodiment

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 to Fig. 5 shows a preferred forms of the present utility model.This paper feed guiding mechanism comprises a loam cake 1, a lower cover 2, and upper and lower covers fastens the back and forms a cavity.Loam cake inside is provided with a ligulate guiding drum 11, and it has protruding cambered surface to lower cover, is respectively equipped with a spacing drum 12 of perpendicular level in the both sides of ligulate drum position.Under cover and be provided with paper feed port 21, inside is provided with the guiding drum 22 that a shape of being made up of four ligulates drums and loam cake ligulate drum are complementary, drum 22 both sides are respectively equipped with a spacing drum 23 of perpendicular level leading.After upper and lower covers fastened mutually, guiding drum 11 and guiding drum 22 formed a paper feed gathering sill 3, and the

spacing drum

12,23 of the level on the upper and lower covers cooperates paper feed gathering sill 3 to finish the paper feed guiding and the position-limiting action of air exercise printed volume paper.

Below just implement a preferred examples of the present utility model, those skilled in the art is done on inferior basis is equal to replacement, all in the description scope of this paper.

Claims
