For the frictional power device of tube rotation
Technical field
The invention belongs to electricity-saving lamp production equipment, relate generally to a kind of frictional power device for tube rotation.
Background technology
In today that the energy reduces day by day, energy-conservationly become upsurge, electricity-saving lamp industry develops rapidly thereupon, the saving aspect of early stage electricity-saving lamp luminance, useful life and the energy exists a lot of not enough, for improving weak point, a kind of novel electricity-saving lamp production equipment arises at the historic moment, and this equipment can make energy-saving lamp tube be in rotation status in the overall drying process, ensure that the bisque on energy-saving lamp tube wall is even, improve electricity-saving lamp quality.The revolving power mechanism of this type of energy-saving lamp manufacturing equipment generally adopts driven by motor at present, and its shortcoming is that cost is high, consumes electric energy large, easily breaks down.
Summary of the invention
For solving the problem, the object of the invention is to propose a kind of frictional power device for tube rotation, making it have that cost is low, energy consumption is little, operate stable feature.
The present invention has been the technical scheme that foregoing invention object is taked: a kind of frictional power device for tube rotation, and described frictional power device mainly comprises frictional disk and to rub the friction pulley producing and rotate with frictional disk; Described frictional disk rotates under actuating unit effect, and described friction pulley is positioned at one end of main shaft and correspondence is arranged on above frictional disk; The other end of main shaft is connected by the transmission mechanism of flexible axle and drive one group of several tube rotation; The friction pulley upper-lower position, the pressure adjustmenting mechanism that are made up of fixed head, U-shaped fixed head, spring and screw are set, described fixed head is fixed on the rolling disc of electricity-saving lamp production equipment, the U-shaped fixed head connected with fixed head is positioned at the sliding tray that movable axle bed both sides set, formation activity axle bed for guide rail, drives the structure that the friction pulley on main shaft, main shaft moves up and down with U-shaped fixed head; Described spring is positioned at groove that movable axle bed sets and on fixed head, arranges the screw acting on spring; Slide up and down to regulate movable axle bed and the pressure of friction pulley Relative friction dish, ensure that the frictional force that friction pulley and frictional disk produce makes main axis, and can not need during rotation, friction pulley to be separated with frictional disk at main shaft.
Described main shaft is provided with the bearing II moved up for main shaft, the movement locus of corresponding described bearing II has boss on electricity-saving lamp production equipment, when movable axle bed, main shaft, friction pulley forward the position of boss to the rolling disc of production equipment, bearing II contacts with boss, and drive activity axle bed moves up along U-shaped fixed head, friction pulley and friction plate is made not to produce frictional rotation, to ensure that energy-saving lamp tube does not rotate in desired location.
A kind of frictional power device for tube rotation that the present invention proposes, produces relative rotation with friction, drives energy-saving lamp tube to rotate, electricity-saving lamp tube rotation is stablized, and not easy break-down, ensure that energy-saving lamp tube manufacturing technique requirent, and it is little to have energy savings, the feature that cost is low.

Embodiment
With specific embodiment, the present invention is illustrated by reference to the accompanying drawings, but does not form any limitation of the invention.
As shown in Figure 1 and Figure 2, a kind of frictional power device for tube rotation, described frictional power device mainly comprises the friction plate be fixed on electricity-saving lamp production equipment base and the friction pulley 6 produced relative rotation with friction plate friction; Described friction pulley 6 is arranged on one end of main shaft 1, and standby tight by two nuts 8, and in order to the bearing pin 7 of fixed friction wheel on main shaft, described bearing pin 7 is vertical with main shaft; The other end of main shaft 1 is connected with flexible axle and forms power output shaft, and mechanism is connected with tube rotation; Described main shaft 1 is connected in movable axle bed 13 by bearing I 10; Described movable axle bed 13 is provided with for the protection of bearing I 10 and the not contaminated axle sleeve 14 of main shaft 1; Described movable axle bed 13 snaps in U-shaped fixed head 12 by the groove that its left and right sides has, the structure that formation main shaft 1, movable axle bed 13 move up and down along U-shaped fixed head 12; Described U-shaped fixed head 12 is fixed on the fixed head 2 of electricity-saving lamp production equipment; Described main shaft 1 is provided with the bearing II 5 for main shaft orientation, the movement locus of corresponding described bearing II 5 has arc boss on friction plate, when friction plate forwards the position of arc boss to, bearing II contacts with arc boss, and drive activity axle bed and main shaft move up, friction pulley and friction plate is made no longer to produce frictional rotation, to ensure that energy-saving lamp tube does not rotate in desired location.
Described movable axle bed 13 has the spring eye of mounting spring 4, described fixed head 2 has the screw 3 acting on spring 4, slide up and down the pressure with friction pulley Relative friction sheet in order to regulate movable axle bed along U-shaped fixed head.
During use, fixed head 2 is fixed on the position that on electricity-saving lamp production equipment, Relative friction dish rotates, the active force of friction pulley 6 Relative friction sheet is regulated by the screw 3 on adjustment fixing plate, namely screw 3 holddown spring 4 makes movable axle bed 13 move down along U-shaped fixed head 12 together with main shaft 1, until the power produced during the motion of friction pulley 6 Relative friction sheet can drive main shaft 1 to rotate; Main shaft 1 is rotated and drives the fluorescent tube rotating mechanism be connected on main shaft 1 by flexible axle to rotate, when on electricity-saving lamp production equipment, Relative friction sheet forwards the position of arc boss to, bearing II 5 contacts with arc boss, and drive activity axle bed 13 and main shaft 1 move up along U-shaped fixed head 12, friction pulley 6 and friction plate is made no longer to produce frictional rotation, to ensure that energy-saving lamp tube does not rotate in desired location.
