Abstract
The utility model discloses a multi-section transmission mechanism comprising a machine frame, a plurality of roller wheels and a driving device. The roller wheels are movably installed on the machine frame through a roller shaft, and the driving device drives the roller shaft and enables the roller wheels to rotate on the machine frame. The driving device is provided with a multitooth ratio output gear transmission mechanism which is provided with a plurality of output shafts of different output transmission ratios. The output shafts are connected with the roller shaft through connecting pieces, thereby enabling the plurality of the roller wheels to rotate respectively at different rotating speeds and adding stable traction in multi-section mode. A piece of abrasive cloth attached to the roller wheels is formed and shaped by a number of times of stretching so that the coating of the abrasive cloth is evenly distributed in thickness, internal stress of the stretching is effectively reduced, tenacity of the abrasive cloth is enhanced, and quality of products in use is ensured.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of multi-section type driving mechanism.
Background technique
At present; The driving mechanism that acts on the abrasive cloth machine mainly comprises drive unit and several running rollers; Running roller is movably installed on the frame through the roller moving axis; Drive unit drive roller moving axis and drive roller wheel is rotated on frame, and the emery cloth that scribbles coating carries out the one-off drawing moulding through the surface of several running rollers, the rotating speed of these several running rollers all is identical traveling at the uniform speed.Yet; Many shortcomings can appear in the emery cloth of disposable drawing and forming, like the stretching of disposable several running rollers of process, are difficult to control the intensity of stretching; And cause in the process that stretches; The phenomenon of caking or fracture appears in the coating on the emery cloth because of internal stress is excessive, have a strong impact on the quality of emery cloth, even emery cloth is broken off and causes product rejection.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, provides a kind of simple in structure, and segmented stretches and avoids the emery cloth stretching to produce excessive internal stress, and guarantees to have stable tractive force to guarantee the multi-section type driving mechanism of quality of product again.
The goal of the invention of the utility model is achieved in that a kind of multi-section type driving mechanism; Comprise frame, several running rollers and drive unit; Running roller is movably installed on the frame through the roller moving axis; Drive unit drive roller moving axis and drive running roller and on frame, rotate; It is characterized in that: said drive unit is provided with multiple tooth specific output gear drive, and said multiple tooth specific output gear drive has the output shaft of several different output velocity ratios, and output shaft is connected with the roller moving axis through link makes several running rollers be the different rotating speeds rotation separately.
According to above-mentioned; The velocity ratio of the output shaft of several of said multiple tooth specific output gear drive increases progressively one by one; The output shaft of the corresponding different drive ratios output of several roller moving axis is connected with it, forms one by one the rotating speed of roller moving axis and is and increases progressively state and be arranged in order on frame.
Wherein, said multiple tooth specific output gear drive is a multilevel gear drive mechanism.
Perhaps, said multiple tooth specific output gear drive is a planetary gear mechanism.
In the said structure, said link is a belt.
Perhaps, said link is a chain.
In addition, said drive unit is a motor.
The utility model improves multi-section type driving mechanism in the existing technology; Combine with drive unit, matching of roller moving axis through multiple tooth specific output gear drive, the output shaft of multiple tooth specific output different drive ratios that gear drive is exported is connected with the roller moving axis, realize rotating with different rotating speed between the roller moving axis; And the roller moving axis promotes gradually with rotating speed and is sequentially arranged on the frame; And then segmented increases stable tractive force, forms the emery cloth that fits on the running roller through the just moulding that repeatedly stretches, and the thickness that the coating of emery cloth is distributed is even; Effectively reduce the internal stress of its stretching again; The phenomenon of avoiding once-through and causing coating caking, drawing crack to occur or break increases the toughness of emery cloth, guarantees the service property (quality) of product.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
According to shown in Figure 1; The said multi-section type driving mechanism of the utility model; To the existing driving mechanism that is used for the emery cloth of one-off drawing moulding; It comprises frame 1, several running rollers 2 and drive unit 3, and running roller 2 is movably installed on the frame 1 through roller moving axis 4, this drive unit 3 drive roller moving axis 4 and drive running roller 2 and on frame 1, rotate.Wherein, Drive unit 3 is provided with multiple tooth specific output gear drive 5; This multiple tooth specific output gear drive 5 has the output shaft 6 of several different output velocity ratios, and this output shaft 6 is connected with roller moving axis 4 through link 7 makes several running rollers 2 be the different rotating speeds rotation separately.This drive unit 3 is a motor, the installation that matches of motor and multiple tooth specific output gear drive 5.Be specially; Several output shafts 6 of this multiple tooth specific output gear drive 5 are exported with the rotating speed of different velocity ratios separately; And being one of a ratio, the velocity ratio that each output shaft 6 is exported increases progressively output; And the output shaft 6 of the velocity ratios of corresponding each the different outputs of several rotatingshafts connects, and the rotating speed that drives rotatingshafts with output shaft 6 is the basis, the rotating speed of rotatingshaft is the state that increases progressively is arranged in order on frame 1.When work; Drive unit 3 drives multiple tooth specific output gear drive 5 runnings; At this moment; Several output shafts 6 of this multiple tooth specific output gear drive 5 rotate with different velocity ratio separately, and then the roller moving axis 4 that is connected with output shaft 6 of drive, thereby make running roller 2 rotations that are installed on the roller moving axis 4.Because the rotating speed of several roller moving axis 4 is and increases progressively state and be arranged in order on frame 1, and the rotating speed of the tractive force respective roller moving axis 4 of this stretching is increased gradually, forms the stable tractive force that increases of segmented; Cause the emery cloth that fits on the running roller 2 to take place repeatedly to stretch and moulding; Effectively avoid the moulding of emery cloth one-off drawing and produce the phenomenon that coating caking, drawing crack occur or breaks, reduce excessive internal stress, realize that segmented increases tractive force; Increase the toughness of emery cloth, guarantee the service property (quality) of product.
According to above-mentioned, for the stability of the utility model, multiple tooth specific output gear drive 5 can be multilevel gear drive mechanism; Make output shaft 6 stable operations of its output; And then produce the stable tractive force that continues, and guarantee that the production operation is normal, further guarantee the quality of product.
Perhaps, multiple tooth specific output gear drive 5 is epicyclic transmission mechanism, and is simple and compact for structure, reduces the production of products cost, makes each output shaft 6 stable operations equally, guarantees quality of product.
In addition, the link 7 of the utility model is belt or chain, can decide according to the situation of reality.
Above-mentioned specific embodiment is merely the utility model effect embodiment preferably, and all or multi-section type driving mechanisms of being equal to identical with this structure are all in the application's protection domain.
