This plain net textile printing machine 1 has one by one by a predetermined space and is arranged on all dyeing and printing devices 11 on the plain net textile printing machine frame 10.The details of dyeing and printing device 11 is described in detail in Fig. 3 (plane).

Be used in the dyeing and printing device 11 rising and the structure of the device 9 of decline screen cloth as mentioned below.

The details of device 9 is illustrated in the Figure 4 and 5.

One assembly 118 with a screen cloth 118b who tightens on rack 118a is to connect like this, promptly, link to each other with a pair of cramp bar 117 that 4 width extends in the endless belt by rack 118a, described rod member 117 is the setting of parallel interval ground on the length direction of endless belt 4.

The two ends that parallel the scraper guide rail 109 of extension with two cramp bars 117 are connected with four supports 115.This support 115 is supporting the end of two cramp bars 117 by the device 9 of connector effect together.

Device 9 comprises that an axle 901, that moves up and down is connected in the vertical moving member 905 that axle 901 actuator 903 and links with the piston 904 of actuator 903 such as cylinder and by a connector 902.

The axle 901 of device 9 is realized being threaded by the adjusting screw thread 116 that can manually rotate on the support 115.Can raise and reduce axle 901 by rotating adjusting screw thread 116, thereby rise and decline assembly 118 with regard to reliable two cramp bars 117.One interval S is arranged between the screen cloth 118b of the carrier portion of endless belt 4 and relative carrier portion, and it can be regulated by the rising or the reduction of assembly 118.

Axle 901 passes vertical moving member 905 and is fixed in wherein.More particularly promptly axle 901 is fixed in the mode of the Kong Zhongyong of moving member 905 matched in clearance.The piston 904 of actuator 903 raises and reduces moving member 905, thereby makes assembly 118, also extensively is that the fabric 7 on the relative endless belt 4 of screen cloth 118b raises and reduction.Two forked arm 117a that extend towards support 115 from the end of two cramp bars 117 scrape the pin 906 that direction extends by one perpendicular to scraper 114 and are fixed in moving member 905.Pin 906 is inserted in the hole among the two arm 117a with matched in clearance.

Because vertical moving member 905 is connected in from two arm 117a of the end extension of two support bars 117 by pin 906, thus rack 118a scrape or the scraper direction of motion (arrow direction among Fig. 3) on a side and opposite side can rotate around an axis perpendicular to the scraper direction of motion.

Be arranged on and scrape two paired on direction scrapers 114 and in Fig. 3, move together on the arrow direction.When last scraper be positioned at one rise from screen cloth 118b or the position that claims to raise on the time, just be positioned at non-ly when scraping state, back one scraper contacts with screen cloth 118b and scrapes to finish by pressure.Two scrapers 114 scrape operation or the inoperation during non-scraping, all be in the conventional mode, thereby their operation and the situation of not operation be need not more particularly to describe.

Among the present invention, when scraper is forwards moving when contacting with screen cloth, screen cloth 118b almost promptly is raised when scraping or a little later in the initial side that scrapes, to reach required purpose.

Described screen cloth can move up in the above described manner and separate with fabric.

Method with separating screen of the present invention can reach following effect.

The method according to this invention, described screen cloth are raised with respect to fabric.When the separation of screen cloth starts from and scrapes Board position and be close to one of rack 118a of scraping origination side end.Because the position of scraper is close to one of the rack 118a that scrapes origination side end, thereby when the screen cloth initial separation, its distance that is experienced when the distance that initial point experienced more tilts than screen cloth the conventional method is short, thereby not too tensioning or not tensioning.

Different with conventional method, method of the present invention has been avoided the screen cloth springing in that time of separating with fabric.Screen cloth can separate with fabric by the described mode that moves upward reposefully scraping when carrying out after the separation of having experienced initial no springing.Thereby can be issued to gratifying printing effect in the situation that does not reduce an operating efficiency in the print cycle with the present invention.

When scraper advanced to the final position, screen cloth was separated fully.

After scraper lifted, rack 118a raise in the end of the opposite side that scrapes origination side, up to screen cloth 118b with rack 118a is whole together is suspended on the fabric.

Fig. 6 (A) (B) shows the situation that initial period of scraping separates with interstage and screen cloth respectively.Fig. 7 (A) and (B) have illustrated the situation that the terminal stage that scrapes and screen cloth and fabric separate fully respectively.Be pointed out that mill base with 30 among Fig. 6 and 7.

Scraping shown in Fig. 6 and 7 is that right-to-left carries out.View can be able to be imagined conversely as for the process of scraping of carrying out from left to right and to be drawn.

According to the present invention, rack assembly and support member can structurally be independent of and be raised under the situation of other member of dyeing and printing device or reduce.Owing to adopt this structure, can use small-sized actuator to raise or reduce screen cloth, perhaps in other words, can with a kind of simplification, mode makes screen cloth rise simply or descends easily.

Like this, the present invention just can be issued to gratifying printing and dyeing effect in the situation that does not reduce an operating efficiency in the print cycle, and, can be by being used for raising and reducing the small-sized of screen cloth and the device simplified rises screen cloth.
