Abstract

The invention discloses a tension control device, which comprises a main driving wheel control mechanism, a rubber roller control mechanism, a synchronous belt, and a belt wheel. The main driving wheel control mechanism comprises a motor, a first synchronizing wheel, a servo reducer, and a main driving wheel which are coupled in turn, wherein the motor drives the first synchronizing wheel to rotate synchronously and indirectly drives the main driving wheel to rotate by driving the servo reducer. The rubber roller control mechanism comprises a second synchronizing wheel, a stepless reducer, a precision reducer, and a rubber roller which are coupled in turn. The second synchronizing wheel is connected with the first synchronizing wheel through the synchronous belt and rotates synchronously, and indirectly drives the rubber roller to rotate by driving the stepless reducer and the precision reducer. The belt wheel is arranged between the main driving wheel and the rubber roller. The belt tension between the main driving wheel and the material belt wheel can be controlled through fast drive of the rubber roller and slow drive of the main driving wheel, and the tension control device has the advantages of simple structure, easy control, and stable tension.

Description

Tenslator

Technical field

The present invention relates to the tenslator that a Seed packaged band unreels.

Background technology

Strip unreels or the degree of tension of the Tension Control strip of rolling, and it is directly determining follow-up operation tension force running condition.Tension force is loose excessively, can make that follow-up operation is in service can't accurately locate strip; High strung of the tension makes strip break easily, causes easy broken belt.

What present strip tenslator adopted is the mode of fork+potential device; Strip is walked around third wheel set on the fork; Control the swing of fork through self tension force that unreels; And potential device detects the amplitude of fluctuation of fork, and strip unreels motor and controls the number of turns that unreels of strip through the detected amplitude of fluctuation of potential device, to realize the control of tension force.

Summary of the invention

The objective of the invention is deficiency, provide a kind of tension force steady, simple in structure tenslator to prior art.

For realizing above-mentioned purpose, the present invention adopts following technical scheme:

A kind of tenslator; Comprise main drive wheel control mechanism, rubber roll control mechanism, band and strip third wheel synchronously; Said main drive wheel control mechanism comprises motor, first synchronizing wheel, servo deceleration machine and the main drive wheel that is coupled in order; Said first synchronizing wheel of said motor-driven rotates synchronously; And through driving the said main drive wheel rotation of driving indirectly of said servo deceleration machine, said rubber roll control mechanism comprises second synchronizing wheel that is coupled in order, stepless reductor, accurate reductor and rubber roll, and said second synchronizing wheel is connected with said first synchronizing wheel through said synchronous band and rotates synchronously; And through driving the said rubber roll rotation of driving indirectly of said stepless reductor and said accurate reductor, said strip third wheel is located between said main drive wheel and the said rubber roll.

Preferably:

Said motor is connected with first connecting shaft through first coupler; Said first synchronizing wheel is fixedly connected on said first connecting shaft; The other end of said first connecting shaft is connected with said servo deceleration machine, and the other end of said servo deceleration machine is captiveed joint with second coupler, and the other end of said second coupler is connected with second connecting shaft; Said second connecting shaft is connected with the 3rd coupler, and said the 3rd coupler is connected with said main drive wheel.

Said second synchronizing wheel is captiveed joint with the 3rd connecting shaft; The other end of said the 3rd connecting shaft is connected with said stepless reductor; Said stepless reductor is connected with said accurate reductor through the tetrad axial organ, and said accurate reductor is connected with said rubber roll through the 5-linked axial organ.

Beneficial technical effects of the present invention is:

According to tenslator of the present invention; Main drive wheel and rubber roll are through same motor-driven; Be provided with a servo deceleration machine between motor and the main drive wheel, be provided with a stepless reductor and an accurate reductor between motor and the rubber roll, make between main drive wheel and the rubber roll inconsistent because of disposing different its operating speed that makes; The speed of final control main drive wheel wants slow than the speed of rubber roll; Strip is walked around main drive wheel and is walked around the strip third wheel again, walks around rubber roll at last and unreels, in this process; Can fast driving and driving at a slow speed of main drive wheel through rubber roll control the strip tension force between main drive wheel and the strip third wheel, this kind Tension Control simple structure and adjusting easy to control and to reach strip tension force steady.
