Abstract

The utility model relates to a single color printing machine which belongs to the technical field of the improvement of printing devices. The single color printing machine is composed of a plate printing cylinder, an impression cylinder, an ink feeding rubber roller, etc., which realize printing by the friction drive between cylinders, and the outer mechanical drive is cancelled. The utility model has the advantages of simple structure, small ground occupation, convenient operation and use and high safety, and can be suitable for single-color printing of various fiber packaging materials.

Description

Single color printing machine

The utility model belongs to printing equipment and improves technical field.

The all outer machine driving of its printing forme roller of printing equipment, impression roller, the printing ink roller that uses before the utility model realizes printing.Outer machine driving is made up of parts such as motor, reductor, belt, belt pulley, chain, gears.The drive structure complexity, floor space is big, and the installation and maintenance technical difficulty is big, and required machine accessory is many, and noise is big during use, and security is little.

Task of the present utility model provides a kind of printing equipment, cancels outer machine driving, in order to overcome above-mentioned shortcoming.

Task of the present utility model is finished like this: motorized pulleys are used as forme drum, add rubber layer, this rubber layer and impression roller, contact for black rubber roll at the forme drum two ends that stud with protruding hectograph, the upper inking roller tube with contact to black rubber roll.The forme drum friction of rotation drives impression roller, rotates to black rubber roll, upper inking roller tube.

Another improvement of the present utility model is oil removal China ink groove to black rubber roll and upper inking roller tube two ends to be set, and its groove is located at and the inboard corresponding position of forme drum two ends rubber layer, can avoid the two ends rubber layer to be linked with printing ink like this, influences transmission.

Compare with outer machine driving printing equipment, this printing equipment is simple in structure, and cost is low, only adopt motorized pulleys be between forme drum rotation and running roller the outer surface frictional drive finish charging, be coated with China ink, actions such as printing, discharging.Hectograph single color printings such as the trade mark of the package that fibrous materials such as this printing equipment adaptation plastics textile material, news printing paper, brown paper, hardboard, gunnysack are made, pattern, literal, the svelteness degree is good, safe in utilization, noise is little, easy to operate, can intermittently or continuously use.

Below the utility model is described in further detail with embodiment:

Fig. 1 is the utility model schematic diagram

With reference to Fig. 1, this printing equipment mainly comprises base ［ 15 ］, forme drum ［ 1 ］, impression roller ［ 6 ］, gives black rubber roll ［ 3 ］ and upper inking roller tube ［ 5 ］, forme drum ［ 1 ］ two ends add rubber layer ［ 2 ］, made for the skin of black rubber roll ［ 3 ］ by oil resistant rubber, the skin of upper inking roller tube ［ 5 ］ also can add oil resistant rubber.Forme drum ［ 1 ］ itself is motorized pulleys, and motorized pulleys are made up of motor and speed reduction gearing, and motorized pulleys constitute the cylinder rotation by the motor rotation through the gear graduation transferring power.Motorized pulleys are approved products, as JYD type oil injection type motorized pulleys.After this printing equipment starts, when forme drum ［ 1 ］ rotates by ［ 9 ］ direction, rub simultaneously impression roller ［ 6 ］ and give the two ends of black rubber roll ［ 3 ］ of its rubber layer ［ 2 ］ makes impression roller ［ 6 ］ and gives black rubber roll ［ 3 ］ respectively by the rotation of ［ 10 ］ and ［ 11 ］ direction.Drive upper inking roller tube ［ 5 ］ for black rubber roll ［ 3 ］ and make it to rotate by ［ 12 ］ direction, printing ink passes to black rubber roll ［ 3 ］ by upper inking roller tube ［ 5 ］, and printing ink is adhered on the protruding hectograph of forme drum ［ 1 ］ equably.The position of oil removal China ink groove is inboard corresponding with rubber layer ［ 2 ］, is bonded on forme drum ［ 1 ］ the two ends rubber layers ［ 2 ］ to avoid printing ink.Meanwhile, Polywoven Bag enters between forme drum ［ 1 ］ and the impression roller ［ 6 ］ by ［ 13 ］ direction, packaging bag with roller rotate be extruded, go up seal, last packaging bag is taken out of by ［ 14 ］ direction, realize printing.The unsettled device of support ［ 8 ］ that the impression roller bearings at both ends is made up of guide rail and spring is adjusted thrust, like this, can adapt to the fibre packing materials of all thickness.Upper inking roller tube ［ 5 ］ and can pass through debugging apparatus ［ 7 ］ for black rubber roll ［ 3 ］ and arbitrarily adjust and advance and retreat, it is evenly suitable to make to quantity of ink.This printing equipment is simple in structure, and floor space is little, the installation of need not laying foundation, the removable and installation level(l)ing device of whole printing equipment.

Claims (2)

1, a kind of single color printing device, mainly comprise base [15], forme drum [1], impression roller [6] and give black rubber roll [3], it is characterized in that motorized pulleys are used as forme drum [1], add rubber layer [2] studding with the forme drum of protruding hectograph [1] two ends, this rubber layer [2] and impression roller [6], contact for black rubber roll [3], upper inking roller tube [5] with contact to black rubber roll [3].

2, device according to claim 1 is characterized in that oil removal China ink groove ［ 4 ］ to black rubber roll ［ 3 ］ and upper inking roller tube ［ 5 ］ two ends being set respectively, and its position is inboard corresponding with forme drum ［ 1 ］ two ends rubber layers ［ 2 ］.
