Abstract
The utility model provides a belt-skipping-prevention transmission mechanism of a fast roller and a slow roller of a roller-type flour mill. The belt-skipping-prevention transmission mechanism of the fast roller and the slow roller of the roller-type flour mill mainly comprises a slow roller transmission wheel, a fast roller transmission wheel, a tensioning wheel, a double-sided synchronous belt, a ratchet wheel and a running pulley, and is characterized in that the two transmission wheels and the tensioning wheel are on the same plane and distributed in a triangular form, the ratchet wheel is connected with the fast roller and a transmission source of the flour mill, the slow roller transmission wheel is connected with the slow roller, the double-sided synchronous belt winds across the fast roller transmission wheel and the tensioning wheel to form a closed loop, one outer edge of the closed loop is in transmission connection with the slow roller transmission wheel, and the fast roller transmission wheel, the ratchet wheel and the running pulley form a friction-type ratchet wheel mechanism. Compared with an existing synchronous belt transmission mechanism of the fast roller and the slow roller of the roller-type flour mill, the friction-type ratchet wheel mechanism composed of the fast roller transmission wheel, the ratchet wheel and the running pulley is used for slowly starting the double-sided synchronous belt to move, the vibration problem and the belt-skipping phenomenon of the synchronous belt when the existing transmission mechanism is started are relieved, and the service life of the synchronous belt is prolonged.
Description
One, technical field:
The utility model belongs to the grain processing field, is specially the anti-jump tape handler of speed roller that uses on a kind of roller flour mill.
Two, background technique:
Roller flour mill is the capital equipment of cereal powder process, relative movement in its working procedure between the speed roller is the closely transmission of switched in opposite, and power, rotating speed, speed ratio and moment of torsion are all more moderate, again wire drawing polishing and roll clearance are regulated the influence of change but owing to be subjected to grinding roller, centre distance can't be fixed when adopting gear transmission, the deviation that the variation of centre distance allows considerably beyond assembling during the two-wheeled operation, gear transmission simultaneously, the chain transmission needs oil lubrication, therefore the transmission of roller flour mill speed roller develops into synchronous band driving type gradually, this improvement has obviously reduced noise, reduce greasy dirt and dyed, improved transmission efficiency.
Roller flour mill speed roller synchronous belt drive mechanism of the prior art adopts three train driving mechanisms more, and its features simple structure has reduced energy consumption and manufacture cost.But because grinding roller weight is big, resisting moment is big when causing milling machine to start, and then causes the too much lax of synchronous band slack list, climbing tooth occurs and jumps zoning, has increased the wearing and tearing to synchronous band, even may cause being with synchronously fracture damage.
Three, summary of the invention:
In order to overcome deficiency of the prior art, the purpose of this utility model provides the anti-jump tape handler of a kind of roller flour mill speed roller, mainly comprise slow roller drive wheel, fast roller drive wheel, Idle wheel, two-sided synchronous band, ratchet and roller, it is characterized in that two drive wheels and Idle wheel are positioned on the plane, distribution triangular in shape, ratchet is connected with fast roller and the transmission power source of milling machine, slow roller drive wheel links to each other with slow roller, the fast roller drive wheel of two-sided synchronous band pile warp and Idle wheel form closed loop, one outside of closed loop is in transmission connection with slow roller drive wheel, fast roller drive wheel, ratchet and roller are formed the friction type ratchet mechanism.
The technological scheme that its technical problem that solves the utility model adopts is:
The anti-jump tape handler of a kind of roller flour mill speed roller, driving mechanism is made up of slow roller drive wheel, fast roller drive wheel, Idle wheel, two-sided synchronous band, drive wheel and Idle wheel are positioned on the plane, distribution triangular in shape, slow roller drive wheel links to each other with slow roller, the fast roller drive wheel of two-sided synchronous band pile warp and Idle wheel form closed loop, one outside of closed loop is in transmission connection with slow roller drive wheel, fast roller drive wheel, ratchet and roller are formed the friction type ratchet mechanism, and ratchet is connected with fast roller and the transmission power source of milling machine.
When milling machine started, the fast roller of motor drives and ratchet rotated, because the effect of frictional force, ratchet drives the roller wedging at the narrow crack place of ratchet with fast roller drive wheel, drives fast roller drive wheel and rotates together, thereby slowly start two-sided synchronous band motion.
The beneficial effects of the utility model are:
Compare with existing roller flour mill speed roller synchronous belt drive mechanism, the friction type ratchet mechanism that the fast roller drive wheel of the utility model utilization, ratchet and roller are formed slowly starts two-sided synchronous band motion, effectively alleviate vibration problems and the zoning of band jumping synchronously in the existing driving mechanism start-up course, prolonged the life-span of synchronous band.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model.
Among Fig. 1: 1. slow roller, 2. fast roller, 3. slow roller drive wheel, 4. fast roller drive wheel, 5. ratchet, 6. roller, 7. Idle wheel, 8. two-sided synchronous band.
Five, embodiment:
As shown in Figure 1, the anti-jump tape handler of a kind of roller flour mill speed roller, comprise slow roller drive wheel 3, fast roller drive wheel 4, Idle wheel 7, two-sidedly be with 8 synchronously, ratchet 5 and roller 6, two drive wheels and Idle wheel 7 are positioned on the plane, distribution triangular in shape, ratchet 5 is connected with fast roller and the transmission power source of milling machine, slow roller drive wheel 3 links to each other with slow roller, the two-sided fast roller drive wheel 4 of 8 pile warps and the Idle wheel 7 be with synchronously forms closed loop, one outside of closed loop is in transmission connection with slow roller drive wheel 3, and fast roller drive wheel 4, ratchet 5 and roller 6 are formed the friction type ratchet mechanism.
During this model utility work, actuating motor drives fast roller and ratchet rotates, because the effect of frictional force, ratchet drives the roller wedging at the narrow crack place of ratchet with fast roller drive wheel, drives fast roller drive wheel and rotates together, thereby slowly start two-sided synchronous band motion.
