Abstract

The utility model relates to a printing rubber roller supporting device of a scroll printer. The characteristics of the printing rubber roller supporting device are as follows: a printing rubber roller is arranged on a wall plate of the printer, a movable bracket is articulated on the wall plate, a supporting bracket is arranged on the movable bracket, a spring and a fixed plate are arranged on the supporting bracket, a printing head corresponding to the printing rubber roller is arranged on the fixed plate, a plate pressing shaft is arranged on the wall plate, a cam used for compacting the supporting bracket is arranged on the plate pressing shaft, a cam cushion block is arranged on the supporting bracket, and two parallel carrier rollers in contact with the printing rubber roller are arranged on the wall plate. The printing rubber roller supporting device utilizes the two carrier rollers to limit the deforming and bending of the printing rubber roller in two directions, so as to lead to uniform force bearing points of the printing rubber roller and to solve the problem of deflection due to pressure on the printing rubber roller by the printing head, thereby improving the printing quality. Moreover, the printing rubber roller supporting device also has the advantages of simple structure and easy manufacturing.

Description

The banner printing machine is printed the rubber roll bracing or strutting arrangement

Technical field

The utility model relates to a kind of banner printing machine and prints the rubber roll bracing or strutting arrangement.

Background technology

The banner printing machine is mainly used in cloth mark text printout.Printhead (thermal head) and following printing rubber roll thereof are the critical components of printer, its known configurations is: the printing rubber roll is installed on the wallboard of printer, on wallboard, be hinged with travel(l)ing rest, carriage is installed on travel(l)ing rest, spring and fixed head are installed on carriage, the printhead corresponding with printing rubber roll is installed on fixed head, on wallboard, be equipped with and press the version axle, on pressure version axle, the cam that is used to compress carriage is installed, and the cam cushion block is installed on carriage.The printing rubber roll of the banner printing machine of this structure is in operation, and to bear pressure bigger, and long-play makes printing rubber roll and axle easy deformation thereof below the printhead, print rubber roll and amount of deflection occurs, especially in the middle of printing effect obviously reduce.

Summary of the invention

The utility model provides a kind of maintenance to print the indeformable banner printing machine printing of rubber roll rubber roll bracing or strutting arrangement for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of banner printing machine is printed the rubber roll bracing or strutting arrangement, comprise wallboard, be installed in printing rubber roll on the wallboard, be hinged on travel(l)ing rest on the wallboard, be installed in carriage on the travel(l)ing rest, be installed in spring and fixed head on the carriage, be installed on the fixed head and corresponding with printing rubber roll printhead, be installed in pressure version axle on the wallboard, be installed in and press being used on the version axle to compress the cam of carriage and be installed in cam cushion block on the carriage, be equipped with on the described wallboard two parallel and with print the carrying rollers that rubber roll contacts.

The advantage that the utlity model has with good effect is: because two parallel and carrying rollers that contact with the printing rubber roll are installed on the wallboard of printer, limited the bending of printing the rubber roll both direction, stress point is average, solved and printed the amount of deflection problem that pressure produced that rubber roll is subjected to printhead, improved print quality; The utility model also has advantage simple in structure, that be easy to make in addition.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

Among the figure: 1, wallboard; 2, printhead; 3, fixed head; 4, hinge; 5, travel(l)ing rest; 6, carriage; 7, press the version axle; 8, spring; 9, cushion block; 10, cam; 11, print rubber roll; 12, carrying roller.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

As shown in Figure 1 and Figure 2, on the wallboard 1 of printer, be equipped with and print rubber roll 11, on wallboard, be hinged with travel(l)ing rest 5 by hinge 4, carriage 6 is installed on travel(l)ing rest, spring 8 and fixed head 3 are installed on carriage, the printhead corresponding with printing rubber roll 2 is installed on fixed head, on wallboard, be equipped with and press version axle 7, on pressure version axle, the cam 10 that is used to compress carriage is installed, the cushion block 9 of cam is installed on carriage.Two parallel and carrying rollers 12 that contact with the printing rubber roll are installed on the described wallboard.Like this,, limited the bending of printing the rubber roll both direction on the wallboard of printer, made printing rubber roll stress point average, solved the problem of printing the rubber roll amount of deflection, improved print quality because two parallel and carrying rollers that contact with the printing rubber roll are installed; The utility model also has advantage simple in structure, that be easy to make in addition.

Claims
