Abstract

The utility model relates to a printer suitable for cylinder workpieces, mainly composed of a print, a print seat, workpiece guide rails, a printing ink disc, etc. The print can do a straight-line reciprocating motion along an X and a Y two directions. When the printer is used for printing, the print presses the cylinder workpieces to do a straight-line motion, and the workpieces opposite to the print and the workpiece guide rails do a pure rolling motion. The utility model has the advantages of simple structure, clearness and beautiful appearance to printed characters and patterns, stable and reliable integral mechanism and convenient and easy replacement to parts, and the printer has convenient and rapid adjustment when the workpieces with different sizes are printed. The utility model can be used for printing characters and patterns on the outer cylinder faces of the cylinder workpieces.

Description

Straight line pull-alongs columnar workpiece printer

The utility model relates to a kind of printer, is specifically applied to the print job of character pattern on the columnar workpiece external cylindrical surface.

Many products all need character pattern such as printed product model parameter and trade mark on its outer surface before dispatching from the factory, for existing columnar workpiece, character pattern on its external cylindrical surface adopts roller driven type equipment to print mostly, there are a series of roller or roller to transmit motion in this kind equipment through friction, each roller surface after the roller surface of printing ink printing ink on first progressively is diffused into, form ink lay relatively uniformly on the printing ink roller of final one-level in the end, type matrix on being loaded on roller (son) face of cylinder is during with relative rolling of afterbody printing ink roller, promptly be printed on one deck printing ink on the type matrix, band type matrix roller is relative with the next stage rubber roller rolls for this, character pattern on the type matrix is printed on the rubber roller surface, when the character pattern on rubber roller part be filled to arc groove in columnar workpiece between during relative rolling, this literal pattern just has been imprinted on the external cylindrical surface of columnar workpiece, this class printing type is indirect printing, the character pattern stroke that is printed is thicker, the writing shade differs, and printing effect is undesirable; Used roller is to be made by rubber mostly, cleans inconvenience, and the life-span is shorter, and changes also inconvenient; When printing the workpiece of different-diameter size, must the careful distance of adjusting between arc groove and the afterbody roller.With regard to these problems of obvious existence, perplexing discharge tube manufacturer as the semi-automatic printer of existing discharge tube always.

Task to be solved in the utility model just provides a kind of novel printer that is specifically applied to printing character pattern on the columnar workpiece external cylindrical surface, directly dip in and on columnar workpiece, print after getting printing ink with seal, the character pattern that is printed is clear, attractive in appearance, printing effect obviously improves, be applicable to the print job of multiple different-diameter dimension workpiece, maintenance of equipment, part exchanging are all more convenient.

For finishing above-mentioned task, the utility model straight line pull-alongs printer mainly is made of parts such as seal 1, stamp seat 2, workpiece guide rail 3, stamping ink pads 7, and inclination alpha＞1 helps workpiece to roll.Seal 1 is packed into by stage clip 5 in the square hole 13 of stamp seat 2, can easily slide relatively between seal 1 and the stamp seat 2 (Y direction), print moving contact of 1 maintenance of pressure head 4 and seal, both have the free degree in the y direction, stage clip 5 requires to have by enough length and precompressions, make and print pressure head 4 in the process of lifting, pressing down, can remain with seal 1 and contact.Seal 1, stamp seat 2 can be done straight reciprocating motion along directions X, and workpiece guide rail 3 is fixed on the frame.When printing pressure head 4 was depressed seal 1, the lower surface type matrix 11 of seal 1 and the distance of workpiece guide rail 3 should be slightly less than the diameter of columnar workpiece 6, guarantee that seal 1 can compress columnar workpiece 6, and pure rolling contact arc length between the two should be greater than the length of type matrix 11.When beginning to print, printing pressure head 4 lifts, stage clip 5 is upspring seal 1, seal 1 moves to dip on the stamping ink pad 7 along directions X gets printing ink, simultaneously can take manual material loading or automatic orientation hopper material loading, columnar workpiece 6 is delivered to original position, when seal 1 is got back to original position, the printing pressure head presses down, seal 1 compresses columnar workpiece 6 along the directions X moving linearly, columnar workpiece 6 relative seals 1 and workpiece guide rail 3 are made pure rolling, and the character pattern of type matrix 11 promptly has been imprinted on the external cylindrical surface of columnar workpiece 6 on the seal 1, and regulating the final position of printing pressure head 4 and the height of stamping ink pad is the columnar workpiece of printable different-diameter size.Test fully shows: the character pattern that this printing type printed is clear, attractive in appearance, and is easy to adjust when printing the workpiece of different-diameter size, and prolonged the service life of seal greatly, and entire mechanism is stable, reliable.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 8 is the vertical view of workpiece guide rail part in the utility model.

Fig. 9 is the front view of seal parts another program in the utility model.

Seal 1 parts are made of seal bar 9 and type matrix 11, seal bar 9 can form through milling with wearability preferred metal material such as brass, surface 8, surface 10 require smooth smooth, type matrix 11 can be customized, nonmetallic materials such as rubber are made preferably can to select wearability for use, require length and width dimensions to be slightly less than surface 10, stick with glue on the surface 10 of seal bar 9.Also can be made into metal character die 16, be pasted on the surface 10, as shown in Figure 9 by a spongy layer 15.

Stamp seat 2 can use wearability preferred metal such as stainless steel through milling, line cutting forming, and also available No. 45 steel etc. after heat treatment have the metal material of higher hardness to make through technologies such as milling, heat treatment, line cuttings.Square hole 13 requires surfacing, roughness smaller or equal to

Keep vertical with surface 12, guarantee gap 0.02～0.05mm between seal bar 9 and the square hole 13, seal bar 14 can easily be slided in square hole 16, when selecting material and processing technology, require stamp seat 2 to have better wear resistance than seal bar 9.

Workpiece guide rail 3 can be made through technologies such as millings with wearability preferred metal material such as stainless steel, also available No. 45 steel etc. have the material of higher hardness to make through technologies such as milling, heat treatment, grindings through heat treatment, the width dimensions of guide pass should require the roughness on surface 14 to be greater than the height of workpiece 6

Pure rolling when guaranteeing that seal 1 compresses columnar workpiece 6, is made between columnar workpiece 6 and the workpiece guide rail 3 in α＞1 °.

Stage clip 5 can be customized, requires to make with stainless steel wire or the spring steel wire of φ 0.05mm.

By the above, promptly can be made into the utility model---straight line pull-alongs columnar workpiece printer.
