Abstract
The utility model discloses a mandrel for paper winding tube, which aims at providing a mandrel which has small bounce, can wind longer paper tubes and enable the paper tubes to easily withdraw, which is realized through adopting the technical proposal of the utility model that the mandrel is made into two parts, namely a driving mandrel and a driven auxiliary mandrel, the main shaft mandrel and the driven mandrel share the same axial cord, the contacting end surfaces of the two mandrels are respectively processed with concave-convex fixed core structures, a driven shaft is combined with a driving shaft during winding tubes, the driving shaft can drive the driven shaft to together rotate, and after finishing winding the tubes, the driven shaft can withdraw.
Description
Technical field
The utility model relates to a kind of device of processing paper tube, especially the effective mandrel of coil paper.
Background technology
Generally all be by axle rotation of motor drives at present in coil paper pipe process, for the paper tube of spooling can be taken out from mandrel smoothly, this mandrel all is to make cantilever beam structure, this cantilever beam structure makes institute's coil paper pipe can not be oversize, otherwise being easy to generate, the mandrel cantilever end beats, pipe crimping can not finely be carried out, and oversize mandrel also make paper tube be difficult to withdraw from from axle.
The utility model content
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the mandrel that coil paper is effective is made initiatively mandrel and passive supplemental support mandrel two parts, initiatively mandrel and by moving mandrel on same straight line, the contact surface of diaxon is processed with the concavo-convex cored structure of deciding respectively, can be done the motion of straight line advance and retreat by moving mandrel with respect to the active mandrel.
The utility model compared with prior art has following beneficial effect:
1, avoided coil paper tube core axle owing to beating more greatly that cantilever produces, it is good to roll out the paper tube quality.
2, can roll up long paper tube, and paper tube withdraws from from mandrel easily.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, main mandrel 1 is inserted in the main shaft 2, main shaft 2 is by antero posterior axis bearing 3 and 5 supportings, the gear 4 that is contained on the main shaft 2 drives main shaft 2 rotations, thereby make the also rotation together of main mandrel 1, recessed centre hole is processed in main mandrel right side, be contained in the bearing seat 7 by moving mandrel 6, bearing seat 7 is contained on the line slideway slide block 8, slide block 8 can be done the advance and retreat motion by relative main shaft core 1 with bearing seat 7 on line slideway 9, made convexity by moving mandrel 6 at left end, just in time match at the right-hand member centre hole with active mandrel 1, when the needs pipe crimping, bearing seat 7 drives by moving mandrel 6 together to left movement, can drive by moving mandrel 6 when making initiatively mandrel 1 rotation and rotate together, be withdrawed to the right together by moving mandrel 6 and paper tube can be moved back from the active mandrel smoothly unload thereby spool rear bearing block 7 drives when paper tube.
The turning motor transmission of gear 4, gear 4 also can be belt pulleys.
The advance and retreat motion of bearing seat 7 can be by cylinder transmission or other mechanical power transmissions.
Claims (1)
- The effective mandrel of a kind of coil paper, the bearing seat that comprises support mandrel, drive the mandrel motor rotating, it is characterized in that: this mandrel comprises initiatively mandrel and passive supplemental support mandrel two parts, initiatively mandrel and by moving mandrel on same straight line, the contact surface of diaxon is processed with the concavo-convex cored structure of deciding respectively, can be done the motion of straight line advance and retreat by moving mandrel with respect to the active mandrel.
