Anilox roll mounting structure
Technical field
The utility model relates to a kind of flexible printing machine, is specifically related to a kind of anilox roll mounting structure of flexible printing machine.
Background technology
Flexible printing machine has the advantages such as machine construction is simple, adaptability for materials is strong, force of impression is little, printing cost is low, the fast quality of print speed printing speed is good, environmental protection.Printing unit is the core of flexible printing machine, printing unit comprises roller, bottom roller and anilox roll, anilox roll needs frequently to carry out installing/dismounting, in prior art, the two ends of anilox roll are undertaken supporting by the rest pad be fixed on inside frame plate, so the operation (i.e. installing/dismounting) of putting into and take out of anilox roll can be quite loaded down with trivial details, inefficiency.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure simply, is beneficial to the installing/dismounting of anilox roll, the anilox roll mounting structure of increasing work efficiency.
The utility model takes following technical scheme:
Anilox roll mounting structure, it is characterized in that: anilox roll is arranged in swing arm, the swing that left and right directions is made in swing arm is arranged, the bottom of swing arm is swing pivot, removal position after swing arm swings left, the pod groove that the front and back axle head of anilox roll is provided with by swing arm top supports, operating position after swing arm swings to the right, the front and back axle head of anilox roll is supported jointly by the supporting endoporus of a pod groove and fixed hub, the hole wall of the supporting endoporus of fixed hub is provided with the lateral openings allowing anilox roll axle head enter, in operating position, swing arm positions locking by locking cylinder.
After adopting technique scheme, anilox roll is when operating position, under the locking effect of locking cylinder, the front and back axle head of anilox roll is supported jointly by the supporting endoporus of a pod groove and fixed hub, and fixed hub fixedly mounts in the inner side of frame plate, is equivalent to the rest pad of prior art, and anilox roll is when removal position, away from other associated components after anilox roll outwards swings with swing arm, so the installing/dismounting of anilox roll can be very easy, greatly increase work efficiency.
As preferably, described locking cylinder is locked swing arm by latch segment, be provided with corresponding to latch segment pin outside swing arm, latch segment does up and down setting along the gathering sill of fixed guide blocks, latch segment is connected with the push rod of locking cylinder, operating position after swing arm swings to the right, latch segment compresses by pin from left side.By above-mentioned design, when latch segment compresses by pin from left side, swing arm will be push and move to fixed hub direction, thus make a pod groove and supporting endoporus close to each other and jointly the axle head of anilox roll held tightly, anilox roll is worked location reliably, ensures printing quality.
As preferably, described swing arm is provided with arc pallet at the inner side near a pod groove and carries out aiding support to the axle head of anilox roll, and arc pallet is fixed in swing arm.The design of arc pallet can ensure that anilox roll does not depart from from swing arm.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of anilox roll of the present utility model when operating position,
Fig. 2 is the structural representation of anilox roll of the present utility model when removal position,
Fig. 3 is the other direction view of Fig. 1.
Detailed description of the invention
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the operation principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in the figure, anilox roll mounting structure of the present utility model, anilox roll 1 is arranged in swing arm 6, the swing that left and right directions is made in swing arm 6 is arranged, the bottom of swing arm 6 is swing pivot, the bottom of swing arm 6 connects swing fulcrum 8, swing fulcrum 8 is rotated and is located on frame plate, removal position (shown in Fig. 2 position) after swing arm 6 swings left, before and after the front and back axle head 11(of anilox roll, axle head is arranged with rolling bearing) the pod groove 61 that is provided with by swing arm 6 top supports, the axle head 11 that swing arm 6 is provided with arc pallet 9 pairs of anilox roll at the inner side near a pod groove 61 carries out aiding support, arc pallet 9 is fixed in swing arm 6, operating position (shown in Fig. 1 position) after swing arm 6 swings to the right, the front and back axle head 11 of anilox roll is supported jointly by the supporting endoporus 31 of a pod groove 61 and fixed hub 3, the hole wall of the supporting endoporus 31 of fixed hub 3 is provided with the lateral openings 32 allowing anilox roll axle head 11 enter, fixed hub 3 fixedly mounts in the inner side of frame plate, in operating position, swing arm 6 positions locking by locking cylinder 4, concrete structure is: described locking cylinder 4 is locked by latch segment 5 pairs of swing arms 6, be provided with corresponding to latch segment 5 pin 7 outside swing arm 6, latch segment 5 does up and down setting along the gathering sill of fixed guide blocks 2, latch segment 5 is connected with the push rod of locking cylinder 4, fixed guide blocks 2 fixedly mounts in the inner side of frame plate.Operating position after swing arm 6 swings to the right, latch segment 5 compresses from left side by pin 7, when latch segment 5 compresses by pin 7 from left side, swing arm 6 will be push move to fixed hub 3 direction, thus make a pod groove 61 and supporting endoporus 31 close to each other and jointly the axle head 11 of anilox roll held tightly, anilox roll 1 is worked location reliably, ensures printing quality.
