Description

Screen printer

The utility model is a kind of novel screen printer with inching screen frame structure and object delivery configuration, relates to the screen painting machine technology.

Present employed vapour-pressure type screen printer, safety for want of, precision is eliminated with the requirement of automation, as for the treadmill formula screen printer that generally uses at present, though can be better than early stage machine, but also there is shortcoming to wait to improve, as shown in Figure 1, a kind of body with adjusting device under the table top, at first, this treadmill type machine is when settling printing screen plate, because of cantilever (1) and transverse slat (2) all do not have adjusting device, so must be by the staff who is skilled in technique, with range estimation or little mode of beaing, go up clamping screen frame (3) in transverse slat (2), and put thin thin object at clamping bar (21) underlay of transverse slat (2), levelness to screen frame (3) is done coarse adjustment, it is trifling very to bother, again by the three groups of adjusting devices (10) that are provided with between treadmill face (400) and bracket (5), level difference between treadmill face (400) and screen frame (3) is finely tuned, but adjusting device (10) is arranged at the frame mode of treadmill, the effect of leaving its adjustment aside for the moment how, only with regard to it is arranged at adjusting device (10) on the structure thing of reciprocal fast moving, promptly belong to a kind of bad method to set up, because treadmill is in back and forth quick wire mark running, must extremely fast not stop back and forth to move, and quick acting certainly leads to oscillation phenomenon, and it is big more to move fast more then vibration, the weight of adding treadmill itself and attached member surpasses 40Kg at least, often be difficult to guarantee that the angle of adjusting deviation does not take place and loses accurate accuracy, cause in the wire mark process, the positioning of treadmill face, under the still unconscious situation of staff, and cause a lot of waste products, and, the adjustment make of this table top, make the staff must note whether deviation of treadmill face constantly, whether the wire mark quality guarantees or the like, its operating efficiency is impacted, moreover, take out workpiece in finishing printing the back, also must be by manually carrying out, so getting material on the other hand, in the interactive action that another hand again must feeding, often under the bigger or heavier situation of workpiece, the operator often feels inconvenience.

The purpose of this utility model is to provide a kind of novel wire mark machine with inching half tone structure and object delivery configuration, and the positioning bias phenomenon takes place in the time of overcoming the fast moving because of the treadmill face, and can automatic material taking.

The technical solution of the utility model is such:

Has cantilever, transverse slat, screen frame, inching screen frame structure and object delivery configuration are housed on the screen printer of treadmill and bracket, wherein inching screen frame structure comprises: be arranged at the advance and retreat adjustment group on the body left and right sides cantilever (1) respectively, inclination angle adjustment group and just adjustment group of level etc., advance and retreat adjustment group is arranged at the relative inner edge surface of two cantilevers, be connected on cantilever with one group of dovetail groove activity of moving seat, and dog screw is set is locked or loosen in moving a seat upper limb face, and fixed head is set in cantilever leading edge end, the outer rim of fixed head is provided with an adjustment rotary head with scale, wear fixed head and move seat composition screw pair with screw rod, mobile seat can be moved forward and backward and produced by the screw rod traction because of adjusting the rotating screw bolt of rotary head; Adjustment group in inclination angle is arranged at the mobile seat below of advance and retreat adjustment group, lives in changeing and is connected with moving seat with two groups of Qian type seats, runs through between two Qian type seats and overlaps slotting axostylus axostyle, and in Qian type seat end locking nut is set, with fastening or loosen the angle of adjusting type seat; Just adjustment group of level, be arranged between Qian type seat and transverse slat, the ladder type piece is set and Qian type seat leading edge is fixed, and holder and transverse slat back of the body edge is fixed, and is connected so that dovetail groove is movable between ladder type piece and holder, and fastening with screw, establish a location-plate in holder upper limb face, this location-plate outer edge surface is provided with a perforation with internal thread, forms screw pair with adjusting the screw break-through with the ladder type piece, can make holder generation upper and lower displacement by adjusting screw turns.The object delivery configuration, laterally the appropriate location is corresponding respectively on print station and pedestal is provided with rail groove and following rail groove on the array, and cooperate the grooved rail position at pedestal two side ends upper limb, drive group and priming group are set respectively, and the lower edge both sides are provided with pneumatic cylinder respectively and the II type is lifted plate, drive group and priming group are respectively by arbor wheel, propping up piece and plaque constitutes, propping up piece is connected in lifting two outsides, plate upper end, two piece outer ends of drive group are provided with adjustable frame plate, arbor wheel is located between the frame plate, two interblocks of priming group are provided with arbor wheel, activity wheel on two groups of arbor wheels is corresponding to the rail groove, two plaques are arranged at the both end sides of print station, two corresponding end respectively are provided with several curved grooves before and after it, and in groove, install arbor wheel, plaque is clamped on a piece, between the adjustable frame plate, between two arbor wheels through several closed hauling ropes of rail groove winding, and in last rail groove below the hauling rope, setting runs through and is connected the support rail bar that the plate upper limb is lifted in both sides, organize a side in drive again and prop up the piece outer rim, establish a dynamic component, with driving belt and drive band rotating shaft wheel, make the hauling rope can be on-stream, by pneumatic cylinder draw and lift that rising emersion print station props up that object is seen off or the retraction that descends on object delivery configuration in the rail groove.
