Consult shown in Figure 1, disclose roller frame (1) among the figure and be the unusual axle type support body of length, its both sides are that axle is located at ［ not shown in the figures ］ on the truss, but truss is the support body of an oscilaltion, when truss rises, swinging or rewind belt on the formula printing machine when moving just, when being printed carrier ［ as towel, T-shirt, paper or the like ］ when moving under the half tone on the belt with belt, belt promptly stops immediately, this moment, truss will descend, and scraper can begin printing on half tone then.

Have a plurality of U type pieces (2) on the roller frame (1), now cooperate one group of knife rest to be described in detail as follows with two U type pieces:

On U type piece, have two hold-down screws (6) and be to be located at screw (7), and side there are two screw rods (31) fixing with vertical spiral shell.And respectively having a fixed block (3) in U type piece two sides, edge central authorities have a screw (8) on the fixed block, can be screwed into by screw (6), and be fixed on the side of U type piece (3); In addition, fixed block has a slotted hole groove (10), can adjust screw rod (12) and cooperate a packing ring (11) to penetrate and be screwed in the screw (9) of U type piece for one.So, fixed block by the adjustment spiral shell (36) of the screw of top (6) and side fixing and unlikely about, dystopy up and down.

Secondly, the bottom of fixed block (3) have an oblique rest shoe (13) and one with the symmetrical also fixture block (14) of oblique setting of rest shoe, within the rest shoe mask have two horizontal rows to pawl groove (16).In addition., have two horizontal rows to the button pawl (15) as the pawl groove in knife rest (4) top outward, this button pawl can laterally be embedded in the pawl groove (16), makes knife rest (4) be fixed on the below of fixed block (3).Because the knife rest button pawl back side is an oblique back side (17), and this oblique back side is face within the fixture block (14) that is affixed on fixed block (3), so makes knife rest can not be partial to or unusual fluctuation.And the fixture block of fixed block (14) has a screw (18), can establish and knife rest (4) is locked for the spiral shell of a fixed screw (19), and it is loosening that knife rest is never had.

In addition, knife rest (4) central interior has the grip slipper (30) of a hollow cell body, its central authorities are corresponding left and right cell wall (28) (29), ratchet body (26) (27), and establish bolt (23) more than some by aperture (20) spiral shell of knife rest one end slot wall (29), make right cell wall (29) can limited cell wall left (28) clamp or lax.Scraper (5) can be installed up in the grip slipper (30) thus, again bolt (23) spiral shell be established to aperture (20), reach fastening and scraper is given clamping.

The both sides of U type piece (2) respectively are fixed with one group of cutter frame structure, and two scrapers (5) in the knife rest are to be symmetry and to be the setting of " eight " font.

Promptly as shown in Figure 2, and the embodiment on printing machine promptly as shown in Figure 3 after the combination of two groups of knife rests.Have a belt (32) in Fig. 3 on the surface of screen printer, putting on the belt has one by carrying printed article ［ being a towel in graphic ］ (33), and in the time of under belt is delivered to towel on half tone frame (34), belt promptly stops to move immediately.At this moment, half tone frame (34) can descend at once together with roller frame (1), and cover and be pressed on the towel.Then, roller frame (1) to other side, makes the interior printing ink of half tone frame bring to end in addition by an end by one of half tone frame (34) side shifting, and printing ink covers through the last pattern of wire side (35) and is printed on towel (33) surface; After the roller frame moves to an other end ［ be on the drawing dotted line partly ］, move back into original position again, printing ink is covered once more be printed on the towel surface, just very Feng Yu, distinctness of the pattern color on the towel surface like this, and be loyal to original copy.

Because two scrapers (5) are to be the setting of " eight " font, thus when pushing away China ink, seal China ink just as Fig. 4, shown in Figure 5.Among Fig. 4, pile up both sides in the half tone frame (34) printing ink, two are between the opposed scraper of " eight " font (5) also to assemble printing ink are arranged, when the knife rest group before roller frame (1) moves, roller frame (1) can be taken advantage of a situation toward a lateral deviation, making wherein, a scraper departs from the half tone face, another scraper then pressing in the half tone face, move on to 2. position by 1. position then, printing ink can very successfully be passed, and this moment, the scraper in left side promoted cutter hub, scraper is moving to 3. position by 2. position, can pause a little while then, the printing ink that this moment, side was piled up can be flowed into by space, two cutter hubs below, to replenish the printing ink that is consumed between two cutter hubs.

In the process of knife rest group and roller frame (1) backhaul as shown in Figure 5, it is to move to 5. position by 4. position, and move to 6. position again, in moving process, roller frame (1) equally also can deflection, its yawing moment with above-mentioned when going journey the direction of deflection opposite, therefore left scraper can deflection have been lifted up, and right scraper just becomes wiping, pushes away China ink, the cutter hub of pressure version.When the roller frame moved the arrival original position, roller frame (1) can be returned again in deflection, makes two scrapers be affixed on the half tone again and is " eight " font.

Whenever roller frame and knife rest group round trip, then half tone and roller frame must rise, and make belt that the towel that prints is moved to next step, carrying out another time printing, and new towel are moved to the below of half tone frame again, with next screen painting that returns of row.

Consult shown in Figure 6, the knife rest (4) that discloses this product among the figure is the casting person through precision, and because the cooperation of material, a left side, right cell wall (28) (29) is that certain elasticity physical property is arranged, when this product clockwise turn bolt (23), right cell wall (29) is slightly to outer displacement, grip slipper (30) spacing strengthens, scraper (5) is can insert in the grip slipper (30), and an alignment left side is withstood at the top that makes scraper, the inner wall of the flange (24) (26) in the right cell wall (28) (29), because the datum-plane of flange is to be set, so scraper (5) is to be the certain level benchmark.

Consult shown in Figure 7, disclose among the figure when clockwise turn bolt (23), then right cell wall (29) is along the screw advancement of bolt (23) and cell wall (28) closing left, when flange (24) closing when flange (25) then displacement movement stop, this moment is left, ratchet body (26) (27) on the right cell wall just closely embedding is pressed on the scraper (5), reach tight clip effect, make the lateral fiducial face of scraper, can reach the levelness of expection and unexpected screw thread with bolt (23) contacts and produces unusual fluctuation, the effect that this kind can accurately be aimed at level reference is that prior art is beyond one's reach.

Because the shape of this product left and right sides cell wall ratchet body (26) (27), system is made of two interior overhead kick teeth and an outward-dipping denticle, characteristic with the scraper of preventing (5) downslide, when pressure is embedded in soft scraper (5), in long-term reciprocal contact movement, unexpected at all its slides downwards or to other position, can reach really to cause the effect of keeping a firm hand on firm scraper, the embedding of more known shape-V thread is pressed, and this product obviously slides than the firm and unexpected scraper of known person and comes off also.

Consult the side cross-sectional schematic that Figure 8 shows that the another kind of knife rest fixed doctor of the utility model (5), by this pattern is slightly different with aforementioned knife rest in described as can be known among the figure, because the cell wall (28) (29) about this knife rest is to be the segregator, and right cell wall (29) promptly is provided with several apertures equally in a trough wall surface position, the set screw (21) of grip slipper (30) is to be corresponding in this aperture (20) and the left cell wall, establish by the spiral shell of bolt (23) thus, the cell wall (28) of right cell wall (29) can being turned left is closely proper, after the chimb (22) at bolt (23) and right cell wall (29) top withstands left cell wall (28), the inside spiral shell of bolt is established to the screw (21) of left cell wall and is promptly stopped displacement action, left and right sides cell wall (28) this moment (29) just closely embedding is pushed down scraper (5), reaches tight clip effect.

Employing the utility model is implemented, and it is comparatively sliding smooth that then screen painting can make stirring with the passing meeting of printing ink, and cutter frame structure is more firm, and printing effect is better, mass colour Feng Ze, distinct beautiful person.
