Description
Technical Field
The utility model relates to a printing machine field, specific theory has related to a roller is received and released in calico printing machine double-end support.
Background
The wind-up roll and the wind-down roll in the existing decorating machine equipment are generally composed of a group of chucks, namely the chucks are respectively extended to two ends of the paper tube and clamped to support and position the paper tube. This kind of structural installation and dismantlement are convenient, but often can appear only the both ends of fiber container can receive better support, and the middle part of fiber container then is in unsettled state, leads to the fiber container middle part to take place bending deformation, and then influences the stability and the printing quality of rolling and unreeling.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a roller is received and released in calico printing machine double-end support to the not enough of prior art.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a double-head supporting and winding-unwinding roller of a printing machine comprises an unwinding roller and a winding roller; the unwinding roller and the winding roller respectively comprise a rotating shaft and a supporting section bar sleeved on the circumferential surface of the rotating shaft;
the supporting section bar comprises an inner positioning sleeve and an outer supporting sleeve sleeved outside the inner positioning sleeve, and the inner positioning sleeve and the outer supporting sleeve are connected through a plurality of connecting rib plates;
a positioning cover plate is arranged on the rotating shaft, positioning mounting holes matched with the positioning cover plate are formed in two ends of the outer supporting sleeve, and the outer supporting sleeve is connected with the positioning cover plate through bolts;
the surface of the outer supporting sleeve is clamped with a plurality of rubber strips, and the rotating shafts are in transmission connection with a winding and unwinding motor.
Based on the above, the rotating shaft and the winding and unwinding motor are in gear transmission.
Based on the above, the length of the rotating shaft is greater than the length of the supporting section bar.
Based on the above, a plurality of rubber strips are fixed on the surface of the outer supporting sleeve through the fixed pressing plate
Based on the above, a plurality of pressing plate fixing grooves are formed in the surface of the outer supporting sleeve, and one end of the fixing pressing plate is clamped in the pressing plate fixing grooves.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a calico printing machine double-end supports and receives and releases the roller and designs into a complete rotation axis through the wind-up roll with having now and release the roller to establish the surface at rotation axis outer peripheral face cover and have the outer support sleeve that prevents the pivoted rubber strip, thereby can make the fiber container wholly can obtain even support when receiving and releasing, effectively avoided the fiber container intermediate position because of supporting the not enough condition of taking place bending deformation. Furthermore, the length of the rotating shaft is larger than that of the supporting section bar, so that the extending parts at the two ends of the rotating shaft form lifting handles, and the winding roller and the unwinding roller can be conveniently mounted on and dismounted from the rack. Furthermore, a plurality of rubber strips are clamped on the surface of the outer supporting sleeve, and the paper tube can be prevented from moving and shaking in the winding and unwinding processes by utilizing the friction force between the rubber strips and the paper tube.
