A kind of printing machine

Technical field

The present invention relates to field of printing machinery, and in particular to a kind of printing machine.

Background technique

Printing machinery is the general designation of the mechanical equipments such as printing machine, binder, platemaking machine and other accessory machineries, modern Printing machine is generally made of mechanisms such as loading, inking, coining, paper feedings.These mechanical equipments have different performance and purposes, because This, the mechanical type for forming them is not exactly the same.And printing machine is the machine of printing word and image.Modern printing machine is general It is made of mechanisms such as loading, inking, coining, paper feedings (including folding).

Its working principle is: printing plate is made in the writings and image that will first print, and fills on the printer, then by artificial Or black be coated on printing plate is had the place of writings and image by printing machine, then is directly or indirectly transferred to paper or other stocks On (such as textile, metal plate, plastic cement, leather, plank, glass and ceramics), to copy printed matter identical with printing plate.Print The invention and development of brush machine play a significant role the propagation of human civilization and culture.

Currently, the Chinese patent of Publication No. CN108372713A discloses a kind of simple reciprocating printing equipment, it is wrapped Printing machine ontology is included, paper feeder is provided on the left of printing machine ontology, is provided with dust-extraction unit, dust-extraction unit on the right side of paper feeder Right side is provided with inking device, and workbench is provided with below inking device, is provided with supporting leg, supporting leg and workbench on the downside of workbench It is bolted；

Workbench front end is provided with the second riser, and the second riser is bolted with workbench, is provided on the inside of the second riser Sliding rail, sliding rail top is provided with third riser, and is slidably connected between third riser and the second riser by sliding rail, third riser Inside is provided with print roller, and shaft is provided on the inside of print roller, and shaft one end is provided with bearing assembly, and bearing assembly and third are perpendicular Plate is bolted.

Although this simple reciprocating printing equipment structure is simple, cost can reduce, its overall structure is larger, though Right structure is simple but component part is more, and weight and required occupied area are all very big, and this printing equipment is placed on small-sized print It in brush shop, needs to overhaul once breaking down, the space of maintenance is smaller, brings great difficulty to service personnel, improves Time, energy and cost needed for maintenance, reduce working efficiency.

Summary of the invention

The object of the present invention is to provide a kind of printing machines, and having can be moved easily, and allow the operator to facilitate inspection The advantages of repairing, time and cost needed for reducing maintenance, improving working efficiency.

Above-mentioned technical purpose of the invention has the technical scheme that

A kind of printing machine is rotated including body, set on the paper feeding cylinder of body side, set on the intracorporal print roller of machine and several The connection deflector roll being connected in body, body is integrally formed with towards ground side is parallel to the mounting plate that ground is arranged, on body Sliding is connected with several wheel bars perpendicular to ground setting, and wheel bar is equipped with ten thousand in the bending setting of " L " font corner, wheel bar end To wheel, the length for taking turns horizontal segment on bar is greater than the width of mounting plate, and universal wheel is set on the wheel bar outside mounting plate, and body is equipped with For driving the slipping mechanism of several wheel bar synchronization-slidings, the lock for fixing it for locking wheel bar is additionally provided in slipping mechanism Tight mechanism, wheel bar, slipping mechanism and retaining mechanism are symmetricly set on the two sidewalls of body about body center's line.

By using above-mentioned technical proposal, when needing printing machine moving out maintenance, operator can star sliding plane Structure, band driving wheel bar slide downwards, and the universal wheel taken turns on bar is contradicted to ground, and slipping mechanism continues to exert a force at this time, universal wheel generation Entire printing machine is supported for mounting plate, thus printing machine can be mobile to all directions under universal wheel effect, facilitates operation Personnel are pushed out to vacant lot repairing.

Such maintenance personal can move printing machine more conveniently, reduce the limitation of space suffered by printing machine, convenient for behaviour Make personnel and overhaul printing machine, time and cost needed for greatly reducing maintenance improve work efficiency.

Further setting: slipping mechanism include be parallel to horizontal plane and be slidably connected at the sliding plate on organism sidewall, if Dry root wheel bar is each attached on sliding plate, and slipping mechanism further includes the sliding component for driving sliding plate to slide up and down.

By using above-mentioned technical proposal, sliding plate is driven to slide up and down by sliding component, due to sliding plate and several Wheel bar is fixed, and sliding plate sliding is just able to drive wheel bar and universal wheel is up and down, replaces mounting plate by universal wheel to realize The purpose that printing machine is integrally supported.

Further setting: sliding component includes two symmetrically set sliding bar, and sliding bar one end level is slidably connected at cunning It moves on plate, and can be rotated around connecting pin, the other end is rotatably connected on body, the connecting pin between two sliding bars and sliding plate Sliding plate is divided into three parts.

Further setting: sliding component further includes two and is symmetrically set and to be horizontally fixed on the driving on body hydraulic Cylinder, it is hinged that output shaft and the sliding bar of driving hydraulic cylinder are connected to one end on body.

By using above-mentioned technical proposal, the output shaft activity of driving hydraulic cylinder drives sliding bar activity, due to sliding bar One end is slidably connected on body, and the other end is hinged with sliding plate, can change its own and sliding plate when sliding bar activity Between angle realize the purpose for pushing wheel bar and universal wheel to change height and the position of sliding plate；And slide bar and cunning Sliding plate is divided into three parts by the connecting pin moved between plate, can be dispersed the thrust for sliding bar, be made each position of sliding plate at the uniform velocity Sliding, avoids inclined happen.

Further setting: sliding component includes the motor reducer being fixed on the machine body, and is set on the output shaft of motor reducer Have the sliding lead screw perpendicular to horizontal plane setting, sliding plate corresponding position is fixed with slipping block, sliding lead screw penetrate slipping block and Sliding plate is simultaneously threadedly coupled with them.
