Drive mechanism between a kind of adjacent conveyor roller
Technical field
The present invention relates to mechanical field, the drive mechanism particularly between a kind of adjacent conveyor roller.
Background technology
In prior art, between adjacent conveyor roller, usually adopt the form of chain gear, but chain gear form, when running into foreign material, usually can block, thus affect whole delivery system.
Summary of the invention
The object of this invention is to provide the drive mechanism between a kind of adjacent conveyor roller, effectively can avoid the jammed phenomenon of conveying roller, thus be beneficial to the stability improving whole delivery system.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: the drive mechanism between a kind of adjacent conveyor roller, comprise frame, two conveying rollers being rotationally connected with described frame, the end, the same side of two described conveying rollers is fixedly connected with the first gear and the second gear respectively; This kind of drive mechanism also comprises the floating drive mechanism be fixedly connected in described frame; The second orienting sleeve that described floating drive mechanism comprises the permanent seat being fixedly connected on described frame, the first orienting sleeve being fixedly connected on described permanent seat, longitudinal sliding motion are socketed on described first orienting sleeve, be fixedly connected on described second orienting sleeve floating seat, be located in described second orienting sleeve and two ends can contact at respectively described permanent seat and described floating seat spring, be rotationally connected with described floating seat and be engaged in the 3rd gear of described first gear and described second gear.
As preferably of the present invention, described floating seat comprises the consistent and halfbody be fixedly connected with by screw of two structures, and be fixedly connected with clutch shaft bearing between two described halfbodies, be socketed with rotating shaft in described clutch shaft bearing, described 3rd geared sleeve is connected to described rotating shaft; Each described halfbody is fixedly connected with half arc body, half arc body on two described halfbodies forms described second orienting sleeve.
As preferably of the present invention, the side of described frame is provided with groove, is rotationally connected useful in second bearing of the described conveying roller one end of socket in described groove; The opposite side of described frame is provided with the notch accepting the described conveying roller other end.
As preferably of the present invention, the diameter of described 3rd gear is greater than the spacing between described first gear and described second gear.
In sum, the present invention has following beneficial effect: structure of the present invention is simple, easy to implement; Even and if between gear, there are foreign material, due to the vertical floating of the 3rd gear, the 3rd gear can be made to decline due to the application force of the first gear and/or the second gear, now foreign material then can come off due to the transmission between gear, and then the 3rd gear can automatically float again, to be again effectively engaged in the first gear and the second gear, thus avoid conveying roller to block, effectively improve the stability of delivery system; Simultaneously being rotationally connected of the second bearing and groove, making when installing conveying roller, can first the second bearing be overturn, so that insert conveying roller, and then overturn the second bearing and be installed on notch to make the conveying roller other end, thus improve the convenience that conveying roller installs; Afterwards installation first gear and the second gear is continued again.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification sheets, as long as but be all subject to the protection of patent law in right of the present invention.
Embodiment: as Figure 1-4, the drive mechanism between a kind of adjacent conveyor roller, comprises the end, the same side that frame 1, two is rotationally connected with conveying roller 2, two conveying rollers 2 of frame 1 and is fixedly connected with the first gear 31 and the second gear 32 respectively.
The present embodiment also comprises the floating drive mechanism be fixedly connected in frame 1.
The second orienting sleeve 43 that floating drive mechanism comprises the permanent seat 41 being fixedly connected on frame 1, the first orienting sleeve 42 being fixedly connected on permanent seat 41, longitudinal sliding motion are socketed on the first orienting sleeve 42, be fixedly connected on the second orienting sleeve 43 floating seat 44, be located in the second orienting sleeve 43 and two ends can contact at respectively permanent seat 41 and floating seat 44 spring 45, be rotationally connected with floating seat 44 and be engaged in the 3rd gear 46 of the first gear 31 and the second gear 32.
It is consistent and be fixedly connected with clutch shaft bearing 442 between halfbody 441, two halfbodies 441 be fixedly connected with by screw that floating seat 44 comprises two structures, is socketed with rotating shaft the 443, three gear 46 and is socketed on rotating shaft 443 in clutch shaft bearing 442; The half arc body 431 each halfbody 441 is fixedly connected with on half arc body, 431, two halfbodies 441 forms the second orienting sleeve 43.
The diameter of the 3rd gear 46 is greater than the spacing between the first gear 31 and the second gear 32.
The side of frame 1 is provided with groove 11, is rotationally connected useful in second bearing 12 of socket conveying roller 2 one end in groove 11; The opposite side of frame 1 is provided with the notch 13 accepting conveying roller 2 other end.
