Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of printing machine, particularly a kind of compression roller of printing machine.
Background technology
At present printing machine include format printing machine and roll-type should brush machine, format should brush machine be that print is realized by galley
Brush, realizes printing during roll printing machine by print roller.
The printing efficiency of roll printing machine is higher, is widely used, and the roll printing machine first having is in printing first by print roller
Side immerse ink in, ink can be attached on the outer circumferential surface of print roller, printed ink to face with the rotation of print roller
On material, in order to ensure printing quality, first have and fabric can be pressed in printing in print roller by rigid pressure roller.Due to adopting
Adhere to ink with the mode in the side immersion ink of print roller, the non-uniform situation of ink thickness that there can be attachment, leads
Color has the depth after causing printing, and printing quality is unable to control；Fabric when fabric is pressed in print roller by rigid pressure roller
Contacted with print roller for line, since print roller is in lasting rotation, the time of contact of fabric and print roller is extremely short, can lead
Cause ink there is no time enough to be transferred on fabric, in order to ensure that printing generally requires to reduce the velocity of rotation of print roller, lead
Cause printing efficiency relatively low.
The content of the invention
The purpose of this utility model is that there are the above problem for existing technology, it is proposed that a kind of hold-down roller of printing machine
Cylinder, the technical problem that the utility model solves are to improve printing quality.
The purpose of this utility model can be realized by following technical proposal：
A kind of compression roller of printing machine, printing machine include casing, are rotatably connected in casing and unreel roller and winding
Roller, is rotatably connected to printing roller positioned at unreeling in the casing, this compression roller is arranged between roller and winding roller
In casing and positioned at the underface of printing roller, it is characterised in that it is described compress roller include ring-shaped section and ring-shaped inner roller and
The outer roller of ring-shaped section and ring-shaped, is fixed, institute between the inner roller and outer roller by some fixed links being radially distributed
The both ends for stating inner roller are connected with housing into rotation, and the inflation pressure cylinder of tubular in a ring, the inflation pressure are cased with outside the outer roller
Cylinder is fixed with outer roller, and the inflation pressure cylinder is made of elastic material, and the inflation pressure cylinder can recline to printing after inflation
On the downside of roller.
Since inflation pressure cylinder has elasticity, punching press pressure cylinder is the mode that face contacts when reclining with printing roller, and is pasted
It is matched during by the outer circumferential surface of face and printing roller, therefore fabric when fabric is acted against on printing roller by inflating pressure cylinder
There can be larger area to abut on printing roller, fabric has the relatively long time to be contacted with printing roller in printing, from
And ink is completely adhered on fabric, improve the effect of printing fabric；The rotation of printing roller can be also improved at the same time
Speed, improves printing efficiency.
In the compression roller of above-mentioned printing machine, snorkel is equipped with the inner roller, is connected on the snorkel
There are some gas tubes, the gas tube is connected through inner roller and outer roller with inflation pressure cylinder, is offered on the inflation pressure cylinder
Some decompression stomatas.Snorkel is connected with air pump, and air pump real-time qi of chong channel ascending adversely into snorkel during use, the gas poured passes through inflation
Pipe even into inflation pressure cylinder in, while gas can from decompression stomata exclude, inflate pressure cylinder in air pressure formed dynamic equilibrium, by
Different in the structure of decorative pattern on printing roller, the inflation pressure cylinder of dynamically balanced air pressure can be supported in the printing roller from different decorative pattern sections
By when real-time adjustment effect pressure on fabric so that the active force that fabric is resisted against on printing roller is kept constant, make
Obtain the effect that ink is attached on fabric to be consistent, improve the effect of printing fabric.
In the compression roller of above-mentioned printing machine, the inflation pressure cylinder is made of silica gel or rubber.
In the compression roller of above-mentioned printing machine, fixed between the inflation pressure cylinder and outer roller by velcro.It is logical
The disassembly and installation of pressure cylinder can conveniently be inflated by crossing velcro.
In the compression roller of above-mentioned printing machine, the decompression stomata is opened in the both ends of inflation pressure cylinder, the decompression
The edge of stomata is fixed with becket.Becket is avoided that at decompression stomata and is torn, and depressurizes the setting position of stomata so that arranging
The gas removed does not interfere with printing.
In the compression roller of above-mentioned printing machine, outside the linear velocity and printing roller that the inflation pressure cylinder outer circumferential surface rotates
The linear velocity that side face rotates is identical.Roller and printing roller is compressed to drive by motor respectively, said structure can cause fabric with
Inflation pressure cylinder is opposing stationary in contact position, and inflation pressure cylinder only serves the effect for compressing fabric.
Compared with prior art, the compression roller of this printing machine has the advantages that to improve printing quality.
