Description

Cylinder screen printer proportion expression gear drive

Technical field:

The utility model relates to the printing machinery technical field, refers in particular to a kind of proportion expression gear drive of cylinder screen printer.

Background technology:

In the printing technology of traditional cylinder screen printer, the circumference circle that workpiece rotates when printing in order to make and the length of silk screen guarantee synchronous operation, must the adapted gear to ensure this synchronous operation, as shown in Figure 1, if how long the active length of half tone 1 has, then require the circumference of lifter wheel 2 how long to have, that is lifter wheel 2 moves on lifter rack 3 and how long has, we can learn thus, the workpiece of different-diameter must adapted the gears of different sizes, this is a kind of time-consuming, bothersome and structure that expend financial resources is used till today on the cylinder screen printer always, brings great inconvenience for the machine user.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of universal cylinder screen printer proportion expression gear drive is provided.

The utility model is achieved by the following technical solution: slide protrudes out the board perpendicular, the tooth bar travelling carriage slides and is embedded in slide, two ends at the tooth bar travelling carriage respectively set firmly a sliding sleeve, the axial line of sliding sleeve is perpendicular to the plane that moves horizontally of tooth bar travelling carriage, each activity plugs elevating lever in sliding sleeve, the top of elevating lever is fixed with lifter rack, gear and lifter rack engagement, lifter rack is folded between gear and the bearing, lifter rack moves horizontally the plane parallel that moves horizontally of plane and tooth bar travelling carriage, side at a sliding sleeve, be movably hinged with the slip fork, at slip fork upper sleeve through one fork sliding sleeve is arranged, fork sliding sleeve and fork slide block are hinged, the fork slide block is embedded in the fulcrum chute, and the fork slide block adjusting screw mandrel that a side of fork slide block is threaded and runs through the fulcrum chute, the fork slide block is regulated the move horizontally plane of the axial line of screw mandrel perpendicular to the tooth bar travelling carriage, the fulcrum chute is installed on the board, is hinged with a half tone travelling carriage that can move horizontally at the other end of slip fork.

The utility model is simple in structure, processing ease, highly versatile, and the processing of different-diameter workpiece only needs a fixing gear just can all handle, reduced operator's labour intensity greatly, and simplified the auxiliary facility of machine, reduced production cost, had extensive market prospects.

Description of drawings:

Accompanying drawing 1 is for commonly using cylinder screen printer workpiece schematic diagram

Accompanying drawing 2 is the utility model structural representation

The specific embodiment:

See accompanying drawing 2, the utility model is: slide 2 protrudes out board 1 perpendicular, tooth bar travelling carriage 3 slides and is embedded in slide 2, respectively set firmly a sliding sleeve 31 at the two ends of tooth bar travelling carriage 3, the axial line of sliding sleeve 31 is perpendicular to the plane that moves horizontally of tooth bar travelling carriage 3, each activity plugs elevating lever 32 in sliding sleeve 31, the top of elevating lever 32 is fixed with lifter rack 33, gear 5 and lifter rack 33 engagements, lifter rack 33 is folded between gear 5 and the bearing, lifter rack 33 moves horizontally the plane parallel that moves horizontally of plane and tooth bar travelling carriage 3, side at a sliding sleeve 31, be movably hinged with slip fork 6, at slip fork 6 upper sleeve throughs one fork sliding sleeve 62 is arranged, fork sliding sleeve 62 is hinged with fork slide block 61, fork slide block 61 is embedded in fulcrum chute 7, and the fork slide block adjusting screw mandrel 71 that a side of fork slide block 61 is threaded and runs through fulcrum chute 7, the fork slide block is regulated the move horizontally plane of the axial line of screw mandrel 71 perpendicular to tooth bar travelling carriage 3, fulcrum chute 7 is installed on the board 1, is hinged with a half tone travelling carriage 8 that can move horizontally at the other end of slip fork 6.

When using the utility model, the workpiece 9 of need printing is attached to an end of gear 5, rise elevating lever 32 by transmission device, rise the lifter rack 33 on top, driving tooth bar travelling carriage 3 again moves back and forth in slide 2,6 of slip forks that are movably hinged in a side of sliding sleeve 31 serve as that the swing point produces swing with fork sliding sleeve 62 and fork slide block 61 hinged points, and then make hinged half tone travelling carriage 8 generations of the other end move horizontally, thereby make half tone 4 abut in the outer surface of the workpiece 9 that needs printing, the reciprocal horizontal movement of lifter rack 33, make the gear 5 that is engaged back and forth rotate, driving needs the workpiece 9 of printing also to produce reciprocating motion, scraper 10 is applied to the outer surface of the workpiece 9 that needs printing equably with printed liquid, and 9 of workpiece finish printing.

If the distance that circumference circle that the workpiece 9 that need print rotates and half tone travelling carriage 8 move is isometric, turn fork slide block is regulated the screw mandrel of screw mandrel 71 1 ends and is regulated knob, make fork slide block 61 rise or descend, it is isometric with the distance of the hinged point of half tone travelling carriage 8 to slip fork 6 with fork sliding sleeve 62 and fork slide block 61 hinged points with the distance of fork slide block 61 hinged points to fork sliding sleeve 62 with the hinged point of slip fork 6 to regulate sliding sleeve 31, that is to say, fork sliding sleeve 62 and fork slide block 61 hinged points are positioned at the centre position of slip fork 6, when tooth bar travelling carriage 3 moves horizontally, the distance that half tone travelling carriage 8 moves is isometric with the distance that tooth bar travelling carriage 3 moves horizontally, direction is opposite, the isometric requirement of distance that circumference circle that the workpiece 9 that having satisfied needs printing rotates and half tone travelling carriage 8 move;

If need one times of the distance that circumference circle that the workpiece 9 of printing rotates moves greater than half tone travelling carriage 8, turn fork slide block is regulated the screw mandrel of screw mandrel 71 1 ends and is regulated knob, make fork slide block 61 descend, the hinged point of regulating sliding sleeve 31 and slip fork 6 is 1 to 2 to the distance of fork sliding sleeve 62 and fork slide block 61 hinged points and fork sliding sleeve 62 and fork slide block 61 hinged points to slip fork 6 with the ratio of the distance of the hinged point of half tone travelling carriage 8, that is to say, fork sliding sleeve 62 and fork slide block 61 hinged points to the distance of sliding sleeve 31 and the hinged point of slip fork 6 be fork sliding sleeve 62 with fork slide block 61 hinged points to the hinged point of slip fork 6 and half tone travelling carriage 8 apart from half, when tooth bar travelling carriage 3 moves horizontally, slip fork 6 is swung as the swing point with fork sliding sleeve 62 and fork slide block 61 hinged points, and because the ratio of distance is 1 to 2, the big end swinging distance of distance is exaggerated one times, be that tooth bar travelling carriage 3 moves horizontally a unit, the distance that half tone travelling carriage 8 moves is two units, and direction is opposite, then, under the condition of same gear 5, the requirement that the distance that moves greater than half tone travelling carriage 8 in the circumference week that the workpiece 9 that having satisfied needs printing rotates is a times;

In like manner, if the circumference circle that needs the workpiece 9 of printing to rotate is greater than or less than the distance that half tone travelling carriage 8 moves, the hinged point that then only need calculate adjusting sliding sleeve 31 and slip fork 6 then can obtain the displacement of correct half tone travelling carriage 8 to distance and the fork sliding sleeve 62 and the ratio of fork slide block 61 hinged points to the distance of the hinged point of slip fork 6 and half tone travelling carriage 8 of fork sliding sleeve 62 with fork slide block 61 hinged points.
