Description

The intaglio press charging and discharging mechanism

[technical field]

The utility model relates to a kind of printing equipment, particularly a kind of charging and discharging mechanism of intaglio press.

[background technology]

Intaglio press on the existing market adopts the inflatable axis handling material mostly, and inflatable axle cost is higher, adopts the inflatable axis handling material simultaneously, and the change of lap action is trouble very, and workload is big, and the lateral attitude that the efficiency of loading and unloading is low, material twists on the material spool is regulated inconvenient; Also have, intaglio press on the existing market, the general double reversing frame blowing that adopts (promptly unreels arm and is provided with two inflatable axles, replace by unreeling revolution of arm during change of lap), the shortcoming that this kind structure exists is: floor space is big, and retractable material coil diameter is subjected to strict restriction, and the impact to support when unreeling revolution of arm is very big, complete machine tension force is exerted an influence, and labour intensity is big during loading and unloading.

[summary of the invention]

Problem in view of present known technology existence, the technical problems to be solved in the utility model is to be to provide a kind of loading and unloading convenience, high, the material volume position adjustments convenience of the efficiency of loading and unloading, little, the retractable material coil diameter of floor space is big simultaneously, the intaglio press charging and discharging mechanism that cost is low.

For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:

The intaglio press charging and discharging mechanism, comprise support, unreel arm and unreeling shaft, unreeling arm is located on the support, unreeling shaft is located at and unreels on the arm, it is characterized in that: described unreeling shaft is made up of two vertex of a cone axles about coaxial mounted, described left vertex of a cone axle is rotatably connected with the left arm that unreels arm, and an end of left vertex of a cone axle is provided with conehead, and the other end is connected with adjusting device; Described right vertex of a cone axle is rotatably connected with the right arm that unreels arm, and an end of right vertex of a cone axle is provided with conehead, and the other end is connected with automatic jack unit, and the conehead of left and right conical apical axis is relative.Described unreeling only established a unreeling shaft station on the arm, unreel arm and can swing with support and be connected, and unreels arm and driven by hydraulic jack.

The structure of two vertex of a cone axles about unreeling shaft of the present utility model adopts, simple in structure, reduce cost, during last volume, adjust left vertex of a cone axial cone head position earlier, at this moment material is rolled into, jack unit action simultaneously automatically heads into the material reel with the conehead of right vertex of a cone axle and promptly finishes volume work, and rolling up the lateral attitude as material has deviation slightly, can regulate the adjusting device of left vertex of a cone axle regulates, very convenient, during last volume, automatic extending-contracting apparatus only needs return to get final product, thus, the utility model loading and unloading are convenient, the efficiency of loading and unloading is high, material volume position adjustments is convenient; Also have, of the present utility model unreeling only established a unreeling shaft station on the arm, floor space is little, retractable material coil diameter is big, only needs during material loading material volume opsition dependent is fixed (material was rolled up and contacted with ground this moment), cylinder action then unreeling to lay on the arm, automatically lift and expect that being rolled onto suitable operating position gets final product, loading and unloading are very convenient, and the automaticity height reduces labour intensity.

[specific embodiment]

As shown in Figure 1, the intaglio press charging and discharging mechanism, comprise support 4, unreel arm 3 and unreeling shaft 1, unreel and only establish a unreeling shaft station on the arm, described unreeling shaft 1 is installed in an end that unreels arm 3, and the other end that unreels arm 3 is hinged on the described support 4, and the mid portion that unreels arm 3 is connected with hydraulic jack 2, the piston rod top of hydraulic jack is connected with joint 5, and joint 5 and described support 4 are hinged.

As Fig. 2,3, shown in 4, described unreeling shaft 1 is by two vertex of a cone axles 8 about coaxial mounted, 9 form, on the described left and right arms that unreels arm 36,7 are coaxially arranged with vertex of a cone axle installing hole, be fixed with bearing block 12 in the vertex of a cone axle installing hole of a left side, the outside end face of bearing block 12 is fixedly connected with cylinder sleeve 15, be provided with slide block 14 (slide block can only slide and can not rotate) in the cylinder sleeve 15 in cylinder sleeve, described left vertex of a cone axle 8 is through in the bearing block 12, by bearing 11 with unreel arm left arm 6 and be rotatably connected, one end of described left vertex of a cone axle 8 is provided with conehead 10, the other end forms with described slide block 14 by bearing 13 and is connected, and is connected with regulating handle 16 on the slide block 14; Be movably equipped with bearing block 20 by bearing 19 in the right vertex of a cone axle installing hole, the cylindrical of bearing block 20 is provided with gear 18, gear 18 is in transmission connection with winding motor 25, simultaneously, right vertex of a cone axle installing hole outside end face is fixedly connected with cylinder sleeve 23, be provided with slide block 22 (slide block can only slide and can not rotate) in the cylinder sleeve 23 in cylinder sleeve, described right vertex of a cone axle 9 is through in the bearing block 20, by bearing 17 and bearing block 20, unreeling arm right arm 7 is rotatably connected, one end of described right vertex of a cone axle 9 is provided with conehead 10, the other end is connected with 22 formation of described slide block by bearing 21, and the conehead that the left and right conical apical axis is provided with is relative, and is connected with cylinder 24 on the slide block 22 that right vertex of a cone axle 9 is connected.

The utility model is work like this, when rolling up on the need, earlier adjust left vertex of a cone axial cone head position by regulating handle, at this moment material is rolled into, cylinder action then heads into the material reel with the conehead of right vertex of a cone axle, next, cylinder action lifts material automatically and is rolled onto suitable operating position, finishes volume work; As expect to roll up the lateral attitude deviation arranged slightly, can regulate left vertex of a cone axle by regulating handle, up to material be rolled onto reach correct position till.During last volume, cylinder action will expect that volume is put on the ground, cylinder action then, and the conehead of right vertex of a cone axle withdraws from the material reel and gets final product blanking.
