Detailed Description
For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.
Example 1
The utility model provides a printing roller convenient to change, roll body 1 including both ends face center is provided with pivot 6, the cover is equipped with the roller shell 4 of compriseing two semi-cylindrical half roller shells 4.1 on the roll body 1, draw-in groove 5 has been seted up to axial on the roll body 1, draw-in groove 5 length is less than roll body 1 length and draw-in groove 5 one end is located and forms opening 8 on the 1 side end face of roll body, the symmetrical breach 2 of seting up a plurality of sizes the same on the roll body 1 of draw-in groove 5 both sides cell wall department, breach 2 bottom and draw-in groove 5 tank bottom are located same horizontal plane, remaining roll body 1 is bellied barrier 7 between the adjacent breach 2, half roller shell 4.1 edge axial evenly is provided with a plurality ofly can with draw-in groove 5 complex hem 3, hem 3 length is the same with breach 2 length, be provided with the fixed establishment 9 that is used.
The working principle is as follows: as shown in fig. 1-3, when the printing roller is normally installed, the folded edge 3 is located in the slot 5 and directly faces the blocking portion 7, so that the roller body 1 and the half roller sleeve 4.1 are kept synchronous in the circumferential direction by using the limiting and blocking effect of the blocking portion 7 on the folded edge 3, the fixing mechanism 9 realizes the relative axial rest of the roller body 1 and the half roller sleeve 4.1, and the whole printing roller can normally perform printing operation. When the roller sleeve 4 needs to be disassembled, the fixing mechanism 9 is firstly enabled to release the axial fixation of the half roller sleeve 4.1, then the half roller sleeve 4.1 is axially moved to move until the folded edge 3 corresponds to the notch 2, finally, the half roller sleeve 4.1 is radially separated from the roller body 1, and the folded edge 3 moves out of the clamping groove 5 through the notch 2. When the half roller sleeve 4.1 is installed, the folded edge 3 is opposite to the notch 2, then the half roller sleeve 4.1 is attached to the roller body 1 in the radial direction, and the folded edge 3 enters the clamping groove 5 through the notch 2. The half roller shell 4.1 is moved axially to enable the folded edge 3 to move axially along the clamping groove 5, the first folded edge 3 moves to the tail end of the clamping groove 5, the two ends of the half roller shell 4.1 are parallel and level with the two ends of the roller body 1, the folded edge 3 corresponds to the blocking portion 7, and finally the fixing mechanism 9 is enabled to fix the two half roller shells 4.1 axially.
During the whole mounting and dismounting process, the half roller sleeve 4.1 can only axially move for the length of one folded edge 3 relative to the roller body 1.
The utility model discloses make the improvement to prior art, set up a plurality of breachs in the draw-in groove both sides, and set up a plurality of hems that correspond with the breach, at whole installation and dismantlement in-process, just to realizing being connected and separating of half roller shell and roll body with staggering through making hem and breach, and then the distance of half roller shell only can roll body hem length of axial displacement relatively, compare and need the distance of roller shell length of axial displacement to realize the installation and dismantle with current roller shell, reduce the demand in printing roller axial space greatly, it is more convenient to make the installation and the dismantlement of roller shell.
Example 2
