Detailed Description

The present application is described in further detail below with reference to figures 1-2.

Referring to fig. 1, a printing roller for a non-woven fabric printing machine includes a roller body 1, and a rectangular printing plate 2 disposed on a sidewall of the roller body 1, wherein a length direction of the printing plate 2 is the same as a length direction of the roller body 1.

Referring to fig. 2, a rectangular mounting groove 3 which is the same as the roller body 1 in the length direction is formed in the side wall of the roller body 1, the area of a notch of the mounting groove 3 is smaller than that of the printing plate 2, and the printing plate 2 can completely cover the mounting groove 3. Four angle steel 4 of fixedly connected with on the back of printing plate 2, four angle steel 4 support respectively on four corners of mounting groove 3, and two adjacent inside walls of mounting groove 3 are laminated respectively to two lateral walls of angle steel 4. Fixedly connected with two pivots 5 the same with 2 width direction of printing plate on the back of printing plate 2, two pivots 5 are located the both ends at the printing plate 2 back respectively, all rotate on the lateral wall of two pivots 5 and overlap and be equipped with rotor plate 6, two rotor plates 6 can insert in mounting groove 3, and the position one-to-one of two rotor plates 6 and the position of 3 relative two inside walls in mounting groove, still fixed cover is equipped with in the pivot 5 and orders about rotor plate 6 and revolves to the torsional spring 7 that mounting groove 3 corresponds the inside wall. Equal fixed connection second card strip 8 on the looks back of two rotor plates 6, the length direction of second card strip 8 is the same with rotor plate 6's width direction, equal fixedly connected with one on the two relative inside walls of mounting groove 3 blocks a first card strip 9 parallel with second card strip 8, and second card strip 8 is close to a surface laminating and blocking that printing plate 2 can be kept away from with first card strip 9 to a surface of printing plate 2. The second card strip 8 is kept away from and has been seted up direction inclined plane 10 on one side of rotor plate 6, direction inclined plane 10 be used for with the cooperation of the edge butt of first card strip 9, when direction inclined plane 10 contradicts first card strip 9, rotor plate 6 will twist reverse torsion spring 7 automatically and let second card strip 8 leave first card strip 9 soon. A trident-shaped pull rope 11 is further embedded on the printing plate 2, two ends of the pull rope 11 are fixedly connected with the two rotating plates 6 respectively, and the other end of the pull rope 11 extends out of the side wall of the printing plate 2 and is fixedly connected with an iron pull ring 12. Force application grooves 13 which are convenient for workers to pull out the printing plate 2 are further formed in the two opposite side walls of the printing plate 2. When needs installation printing plate 2, the workman inserts four angle steel 4 and two rotor plates 6 simultaneously in mounting groove 3, the edge of first card strip 9 will be contradicted earlier and lead inclined plane 10, under the conflict of first card strip 9 and the guide effect of direction inclined plane 10, rotor plate 6 and second card strip 8 will leave first card strip 9 soon, rotor plate 6 and first card strip 9 can continue to insert in mounting groove 3, when the back of printing plate 2 supports on the lateral wall of roll body 1, second card strip 8 will just be located between first card strip 9 and the 3 tank bottoms of mounting groove, rotor plate 6 receives under the resilience effect of torsional spring 7 will revolve to on the inside wall that mounting groove 3 corresponds, second card strip 8 will be along with rotor plate 6 synchronous revolution and detain on first card strip 9, the position of rotor plate 6 will be locked, printing plate 2 just succeeds in being installed on roll body 1. If the printing plate 2 needs to be detached to replace or clean the printing plate, a worker pulls the pull rope 11 outwards, the two rotating plates 6 are drawn together under the driving of the pull rope 11, the second clamping strips 8 on the rotating plates 6 can be separated from the corresponding first clamping strips 9, and the worker can insert fingers into the force application grooves 13 to pull out the printing plate 2.
