Description

Wear-resisting galley roller

Technical Field

The utility model relates to the field of printing technology, especially, relate to a wearability galley roller.

Background

The plate roller is also called a steel roller. The method is divided into a hollow roller and a solid roller, a roller with a shaft and a roller without a shaft, and is generally used for plate making, the surface of a roller is plated with copper, patterns are carved by an electronic engraving machine of a gravure plate, and then a layer of chromium is plated. Wearing and tearing are inevitable at the in-process that uses, and only through the degree that adopts the different reducing wear of material, current version roller forms the wearing layer through directly plating chromium on the cylinder surface, prevents wearing and tearing, but when wearing and tearing damage appears in the wearing layer, is not convenient for change the wearing layer, is unfavorable for the life of version roller.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that the wearing layer was not convenient for change that exists among the prior art, and the wearability galley roller that proposes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a wearability galley roller, includes the connecting roll, the connecting roll both ends are all welded there is the pivot, two all set up threaded hole in the pivot, two all overlap in the pivot and be equipped with the go-between, and the internal diameter of go-between and the diameter phase-match of pivot, two threaded connection has fastening bolt on the go-between, the fastening bolt screw thread runs through the go-between and extends into threaded hole, the equal fixedly connected with connecting rod in go-between both sides, two connecting rod one end fixedly connected with U-shaped clamp splice, the connecting roll outside cover is equipped with the wearing layer, U-shaped clamp splice and wearing layer looks joint, be provided with stop gear on the U-shaped clamp splice.

Preferably, stop gear is including seting up the spacing groove in both sides about the connecting roll, equal fixedly connected with stopper on the inner wall about the wearing layer, the stopper slides and sets up at the spacing inslot.

Preferably, the wear-resistant layer comprises a reinforcing layer, and a chromium coating is fixedly connected to the inner wall of the reinforcing layer.

Preferably, the fastening bolt is a stainless steel bolt.

Preferably, the inner diameter of the wear layer is matched with the outer diameter of the connecting roller.

The utility model provides a pair of wearability galley roller, beneficial effect lies in: through the design of U-shaped clamp splice, screw hole, fastening bolt, go-between, stop gear, play fixed effect to the wearing layer, also be convenient for dismantle the wearing layer simultaneously to change the wearing layer, be favorable to prolonging the life of version roller.

In the figure: the device comprises a rotating shaft 1, a connecting ring 2, a connecting rod 3, a U-shaped clamping block 4, a connecting roller 5, a wear-resistant layer 6, a limiting block 7, a limiting groove 8, a threaded hole 9, a fastening bolt 10, a reinforcing layer 11 and a chromium-plated layer 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, a wear-resistant printing plate roller comprises a connecting roller 5, rotating shafts 1 are welded at two ends of the connecting roller 5, threaded holes 9 are formed in the two rotating shafts 1, connecting rings 2 are sleeved on the two rotating shafts 1, the inner diameters of the connecting rings 2 are matched with the diameters of the rotating shafts 1, fastening bolts 10 are connected to the two connecting rings 2 in a threaded manner, the fastening bolts 10 are stainless steel bolts, the threads of the fastening bolts 10 penetrate through the connecting rings 2 and extend into the threaded holes 9, connecting rods 3 are fixedly connected to two sides of the connecting rings 2, a U-shaped clamping block 4 is fixedly connected to one end of each of the two connecting rods 3, a wear-resistant layer 6 is sleeved on the outer side of the connecting roller 5, the inner diameter of the wear-resistant layer 6 is matched with the outer diameter of the connecting roller 5, the U-shaped clamping block 4 is clamped with the wear-resistant layer 6, the wear-, when the wearing layer 6 needs to be replaced, the connecting ring 2 is disassembled by loosening the fastening bolt 10, the limitation of the U-shaped clamping block 4 on the wearing layer 6 is removed, and the wearing layer 6 is taken down and replaced.

Be provided with stop gear on U-shaped clamp 4, stop gear is including seting up the spacing groove 8 in both sides about connecting roller 5, equal fixedly connected with stopper 7 on the inner wall about wearing layer 6, and stopper 7 slides and sets up in spacing groove 8, when connecting roller 5 rotates, because stopper 7 sets up in spacing groove 8, will drive wearing layer 6 and rotate, prevents that the wearing layer 6 condition of skidding from appearing.
