Abstract
The utility model discloses a novel vertical transmission mechanism for synchronous belts. The vertical transmission mechanism for the synchronous belts is characterized by comprising a clutch assembly, a tensioning mechanism, a power gear, a main drive gear, an auxiliary drive gear, a tension pulley, a shaft and two synchronous belts, wherein the power gear is connected with a motor to obtain motive power and then transmits the motive power to the main drive gear through the synchronous belts and the clutch assembly, and the main drive gear is connected with the shaft; and after obtaining the motive power, the main drive gear drives the shaft to rotate so that an upper scanning assembly can be fed with the motive power. The shaft is raised along with the upper scanning assembly and then upwards rotated at a certain angle, the main drive gear rotates downwards to loose the synchronous belts, and the tensioning mechanism is outwards shifted at the moment so that the synchronous belts can be tensioned again; and the width of the main drive gear is large enough to ensure that the synchronous belts can not slide down wherever the main drive gear is positioned.
Description
Technical field
This mechanism is mainly used in the electronic equipments such as intelligent reading machine, high speed scanner, high-speed printer, is used for solving this kind equipment and goes up scan components in the last problem of being with tensile force in the journey synchronously that climbs over.
Background technology
Intelligent scanning reading machine or scanner are in use owing to may run into the paper paperboard or transfer machine the time, need sometimes last scan components is lifted certain angle conveniently to get paper or accent machine.And, realize that scan components wants steady operation in the normal position for the train of utilizing the power of band transmission synchronously, and certain angle of can overturning can also continue use returning to original position, does not influence the transmission of power.Under this design background, the vertical transmission mechanism of novel synchronization band has just arisen at the historic moment.
Summary of the invention
Lift shortcomings such as inconvenience in order to overcome the last scan components of using in the existing reading machine, the purpose of this utility model provides the vertical transmission mechanism of a kind of synchronous band, this transmission mechanism can guarantee will go up at any time scan components and lift when providing power for last scan components, conveniently taking-up institute paperboard is opened or carried out equipment debugging.
To achieve these goals, the utility model by the following technical solutions: it comprises clutch pack, strainer, power gear, main drive gear, auxiliary driving gear, regulating wheel, axle and two synchronous bands;
Dynamic reception gear of described clutch pack and power transmission gear, can rotate simultaneously, power receives gear and links to each other with power gear by being with synchronously, and power transmission gear and main drive gear, auxiliary driving gear, regulating wheel, strainer link together by a synchronous band; It is inboard that power transmission gear, main drive gear, auxiliary driving gear, strainer all are in synchronous band, and regulating wheel is in the synchronous band outside.
The fixed installation of auxiliary driving gear, main drive gear links together with axle, between main drive gear and the axle bearing pedestal is arranged, and axle can turn an angle in vertical plane; When lifting on axially, main drive gear i.e. down motion, and axially down during motion, main drive gear promptly moves upward;
Strainer comprises regulating wheel, support, spring and a spring dead plate; Regulating wheel is installed in support one end, and support is that central point can swing with the other end, and spring is installed between support and the spring dead plate, and spring is in extended state all the time.
Power gear links to each other with motor, power is provided for whole transmission mechanism, the power of power gear rotating band dynamic clutch assembly receives gear and rotates, the power transmission gear of clutch pack is along with rotation, by synchronous band effect, master/auxiliary driving gear and then rotates, and the rotating band moving axis of main drive gear rotates, thereby power is provided for the last scan components that is installed on the axle.The travelling gear that links to each other with axle imposes on synchronously with a power that makes progress, and the regulating wheel fixed installation is given all the time synchronously with a downward pressure, and the regulating wheel in the strainer also adds a downward pressure to synchronous band application, makes synchronous band be in tensioning state.
Last scan components is installed on the axle, to go up scan components lifts, axle up rotates in vertical plane, travelling gear moves downward, and band loosens synchronously, and the power that makes progress that strainer is added by synchronous band application reduces, spring retraction in the strainer, strainer outwards moves, and its power that imposes on synchronous band increases, and makes to bring back to tensioning state synchronously.
The main drive gear width is wide than other gear, and when assurance was lifted to maximum angle with axle, band can be from landing on the main drive gear synchronously.
The utility model can be opened institute's paperboard taking-up easily or carry out equipment debugging, and is easy and simple to handle, practical, simplifies job step.

Embodiment
The utility model is with vertical transmission mechanism to comprise clutch pack, strainer, power gear, main drive gear, auxiliary driving gear, regulating wheel, axle and two synchronous bands synchronously.
As shown in Figure 1,1 is power gear, and 2 is regulating wheel, and 3 is main drive gear, and 4 are the auxiliary driving gear, and 5 is to be with synchronously, and 6 is strainer, and 7 is axle, and 8 is clutch pack, and 9 is synchronous band, and 10 is bearing pedestal.
Between power gear 1 and the clutch pack 8 by being with 9 to be connected synchronously, clutch pack 8 and regulating wheel 2, main drive gear 3, auxiliary driving gear 4, strainer 6 are by being with 5 to link up synchronously, and it is inboard that clutch pack and main drive gear, auxiliary driving gear, strainer all are in synchronous band, and regulating wheel is in the synchronous band outside.
As shown in Figure 2, main drive gear 3 is applied an outside power with 5 synchronously, 2 pairs of synchronous band applications of regulating wheel add an inside power, strainer 6 adds an outside power for synchronous band application, auxiliary driving gear 4 and clutch pack 8 are all to synchronously with an outside power, band is subjected to four outside power synchronously, and an inside power is in tensioning state.
When last scan components paperboard, it is lifted, turn an angle on axially, simultaneously, main drive gear moves down, and its power that imposes on synchronous band reduces, and band loosens synchronously; When band loosens synchronously, the power that imposes on strainer reduces, two reciprocal power that regulating wheel in the strainer is applied by synchronous band and spring, when band tensioning synchronously, reach balance, when the power that adds when synchronous band application reduces, spring since the elasticity of self toward retraction, the support that drives strainer is swung to the right, regulating wheel moves outward, makes to bring back to tensioning state synchronously.In like manner, to go up scan components and put back to original position, get back to former horizontal level axially, main drive gear moves upward and gets back to original position, and it imposes on the outside power of synchronous band increases, and band affacts the power increase of strainer synchronously, spring is stretched again, the support of strainer is swung left, and regulating wheel moves inward, and makes to bring back to tensioning state synchronously.
The width of main drive gear is wide than other gear, supposes that the main drive gear width is L, and the maximum angle that main drive gear rotates is θ, as long as guarantee Lcos θ greater than the synchronization bandwidth degree, no matter then where main drive gear is in, band can landing synchronously.
