The telescopic mechanism of locing up of satellite-type flexible printing machine
Technical field
The utility model relates to a kind of mechanism of locing up of satellite-type flexible printing machine.
Background technology
Present stage, the domestic satellite-type flexible printing machine that is using is monoblock type forme and monoblock type anilox roll, its design feature is: all-in-one-piece printing plate cylinder or monoblock type anilox roll are fixed on two side shaft holders, bearing block is connected on the line slideway and can moves forward and backward, and bearing block is generally split type structure and takes out with convenient.When after printing work is finished, needing to change printing plate cylinder or anilox roll, all-in-one-piece printing plate cylinder or monoblock type anilox roll together with two side shaft holders dorsad center roller direction move to the position of suitable space, open the split-type shaft bearing, with artificial or aid all-in-one-piece printing plate cylinder or monoblock type anilox roll are pulled down from machine, changed printing plate cylinder or the anilox roll share.With 2 meters wide degree printing machine is example, about 180~400 kilograms of its printing plate cylinder weight, because spatial constraints, it is very difficult and time-consuming more to change jobs.In general, the printing plate cylinder of one 8 look machine of replacing and anilox roll need two working days.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of mechanism of locing up of satellite-type flexible printing machine, shortens to lock up the time, increases work efficiency and shortens the time of delivery, increases the market competitiveness of satellite-type flexible printing machine.
In order to solve the problems of the technologies described above, the telescopic mechanism of locing up of satellite-type flexible printing machine of the present utility model, comprise printing plate cylinder and the line slideway that is arranged on the printing plate cylinder both sides, described printing plate cylinder is made up of printing plate cylinder mandrel and the telescopic forme that is sleeved on its outside, one end of printing plate cylinder mandrel is positioned on the rest pad, the other end is connected with the printing plate cylinder drive motors, the line slideway that is positioned at rest pad one side is provided with can be along its bearing block that moves, and this bearing block is provided with the turning cylinder that passes rest pad.
As improvement of the technical scheme, described telescopic forme is that rubber-like composite glass fiber material is made, and the surface of described printing plate cylinder mandrel is provided with and is used to carry compressed-air actuated radial hole.
As further improvement in the technical proposal, the end of described printing plate cylinder is provided with horizontal register mechanism, this horizontal register mechanism comprises the bracing frame of fixedlying connected with the printing plate cylinder drive motors, has transverse mobile motor to drive this support movements by horizontal mobile ball screw.
The beneficial effects of the utility model are: the telescopic mechanism of locing up of this satellite-type flexible printing machine is when needs are changed forme, can the operating axis bearing along turning cylinder backward the translation moving axis that rotates again rotate, make printing plate cylinder become cantilever structure, telescopic forme can be extracted out from the printing plate cylinder mandrel very easily, shorten and lock up the time, increase work efficiency and shorten the time of delivery, increase the market competitiveness of satellite-type flexible printing machine.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plate change view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the telescopic mechanism of locing up of satellite-type flexible printing machine of the present utility model, comprise printing plate cylinder 1 and the line slideway 2 that is arranged on printing plate cylinder 1 both sides, it is characterized in that described printing plate cylinder 1 is made up of printing plate cylinder mandrel 11 and the telescopic forme 12 that is sleeved on its outside, one end of printing plate cylinder mandrel 11 is positioned on the rest pad 3, the other end is connected with printing plate cylinder drive motors 4, the line slideway that is positioned at rest pad 3 one sides is provided with can be along its bearing block that moves 5, and this bearing block 5 is provided with the turning cylinder 6 that passes rest pad 3.The telescopic mechanism of locing up of this satellite-type flexible printing machine is when needs are changed forme, can operating axis bearing 5 along turning cylinder 6 backward the translation moving axis 6 that rotates again turn to not interference position, make printing plate cylinder become cantilever structure, telescopic forme can be extracted out from the printing plate cylinder mandrel very easily, shorten and lock up the time, increase work efficiency and shorten the time of delivery, increase the market competitiveness of satellite-type flexible printing machine.
Described telescopic forme 12 is that rubber-like composite glass fiber material is made, and the surface of described printing plate cylinder mandrel 11 is provided with and is used to carry compressed-air actuated radial hole.When changing telescopic forme 12, open baroswitch and feed compressed air to printing plate cylinder mandrel 11, compressed air forms uniform mattress by radial hole to printing plate cylinder mandrel 11 and telescopic forme 12 faying faces, expands thereby pressure enlarges telescopic forme 12 internal diameters and withdraws from from printing plate cylinder mandrel 1 very easily.Equally, new telescopic forme also can be installed on the printing plate cylinder mandrel easily.Close and discharge compressed air, telescopic forme can shrink tightly to be wrapped on the printing plate cylinder mandrel and become one.Whole replacing process approximately needs 15 minutes, and the replacing time of monoblock type printing plate cylinder shortens a lot relatively.And telescopic forme 12 is the composite glass fiber material, and each Mi Zhiliang of telescopic forme of diameter 200mm has only 4~10 kilograms, and is very light.
The end of described printing plate cylinder 1 is provided with horizontal register mechanism 7, this horizontal register mechanism 7 comprises the bracing frame 71 of fixedlying connected with printing plate cylinder drive motors 4, there is transverse mobile motor 72 to drive this bracing frame 71 motions, realizes the horizontal register of printing plate cylinder 1 by horizontal mobile ball screw 73.
In addition, the both sides of described printing plate cylinder 1 are respectively arranged with first, second servomotor 8,9, and this first, second servomotor 8,9 moves with horizontal register mechanism 7 by first, second screw mandrel 13,14 driving shaft bearings 5 respectively.When beginning to print, described printing plate cylinder 1 moves (being called combined pressure) along line slideway to the central impression roll tube; After finishing printing, described printing plate cylinder 1 along line slideway dorsad the central impression roll tube move (being called tripping).
