Abstract
A power transmission mechanism for a bag opener comprises a direct-driven motor. The rotation shaft on one end of the motor is connected with the upper shaft via a coupling and the rotation shaft on the other end of the motor is firm-jointed with a driving single-wheel. The lower shaft is interlinked with the upper shaft via two synchronous belt wheels and belts. The inventive motor is directly connected with the armshaft of the bag opener.
Description
Technical field
The present invention relates to a kind of power-transmitting unit, particularly a kind of power-transmitting unit of bag-opening machine.
Background technique
Formerly the power-transmitting unit of bag-opening machine is in the technology:
Motor 10 as power source is actuating motors, and motor 10 drives 7 rotations (seeing accompanying drawing 1) of bag-opening machine driving wheel by drivign belt 9, and driving wheel 7 is fixedlyed connected by fastening screw trip bolt 8 with last 1.Thereby driving wheel 7 rotations make axle 1 rotation.Last axle 1 makes rotation light sliding with bearing 2 drive fits that are contained on the casing.Go up axle 1 then by two synchronous pulleys 4 and be with 5 power is passed to lower shaft 6 to make it rotation synchronously, thereby driven whole bag-opening machine running, realize sewing work.Synchronous pulley back-up ring 3 plays assurance synchronously with the 5 not effects of play on axial position.
This driving mechanism is owing to adopted belt, and along with the increase of frequency of utilization, belt constantly is worn, and belt very easily produces deterioration phenomenon.So just will occur between belt and the driving wheel, skidding between motor and the belt, both caused the power of motor waste.Also can cause machine startup and stop slow in reactingly, cause complete machine oscillation.Sometimes may pollute sewing in addition, the belt of rotation more can be involved in the end of a thread and foreign material, brings unnecessary trouble to production, wastes time and energy.
Summary of the invention
To the objective of the invention is the problem that exists in the above-mentioned technology formerly in order overcoming, the deficiency in the technology formerly to be improved, a kind of advanced direct driving force driving mechanism is provided.It is simple, convenient to have assembling, thoroughly stops above-mentioned because the bad phenomenon that belt brought, the cost that improves the speed of sewing action and working efficiency and reduce bag-opening machine.
The present invention for this technological scheme of taking is: power source adopts light-duty advanced person's direct-drive motor.Change original driving mechanism, ban belt.Comprise axle, be contained on the casing bearing that cooperates with last axle, by two synchronous pulleys and lower shaft, direct-drive motor, coupling and the active single-wheel of band and last Spindle Links synchronously.The rotating shaft of direct-drive motor one end is connected with last axle by coupling, and the rotating shaft of the direct-drive motor the other end is fixedlyed connected with the active single-wheel.
As above-mentioned structure of the present invention, when direct-drive motor turns round, directly drive upward axle rotation, last axle makes the lower shaft rotation by two synchronous pulleys and synchronous band, thereby has driven whole bag-opening machine running, realizes sewing work.
Power-transmitting unit effect of the present invention is remarkable.
Because driving mechanism of the present invention does not have the driving medium belt, thereby there are not wearing and tearing and power dissipation.Again since the axle of going up of motor and bag-opening machine directly is connected, make machine startup with stop to be quick on the draw, move accurate positioning, do not have the pollution sewing and be involved in the trouble of the end of a thread foreign material.Noise and vibrations have been reduced.Time saving and energy saving.Because driving wheel of the present invention need not hang drivign belt again, so the structure of driving wheel simple than technology formerly, so driving wheel of the present invention is called initiatively single-wheel.
Description of drawings
Fig. 1 is formerly in the technology, the perspective exploded view of bag-opening machine power-transmitting unit.
Fig. 2 is the decomposing schematic representation of the power-transmitting unit of bag-opening machine of the present invention.
Embodiment
Further specify the structure of power-transmitting unit of the present invention below in conjunction with accompanying drawing.
As shown in Figure 2, comprise: comprise axle 1, be contained on the casing bearing that cooperates with last axle 2, two synchronous pulleys 4, synchronously with 5, by two synchronous pulleys 4 and synchronously with 5 with last 1 lower shaft that links 6, direct-drive motor 13, coupling 11 and active single-wheel 15.
Have coupling clamping screw 12 on the said coupling 11.
Rotating shaft as direct-drive motor 13 1 ends of power source is fixedlyed connected with coupling 11 by coupling clamping screw 12, and coupling 11 is same then fixedlys connected with last 1 by coupling clamping screws 12.Realize that direct-drive motor 13 directly is connected with last axle 1.When direct-drive motor 13 rotations directly make axle 1 rotation.Last axle 1 makes it rotate light the cunning with bearing 2 drive fits that are contained on the casing.Last axle 1 is by two synchronous pulleys 4 and be with 5 power is passed to lower shaft 6 to make it rotation synchronously, thereby has driven whole bag-opening machine running, realizes sewing work.Synchronous pulley back-up ring 3 plays assurance synchronously with the 5 not effects of play on axial position.Direct-drive motor 13 is fixed on the casing by mounting screw 14.Initiatively single-wheel 15 is fixedlyed connected with the rotating shaft of direct-drive motor 13 the other ends by Cock screw 16, has substituted the driving wheel effect in the technology formerly.And active single-wheel 15 structures of the present invention are more simple in structure than technology driving wheel formerly.
Claims (4)
1, a kind of power-transmitting unit of bag-opening machine, comprise axle, be contained on the casing bearing that cooperates with last axle, two synchronous pulleys, synchronously band, by two synchronous pulleys and the lower shaft of band and last Spindle Links synchronously, it is characterized in that comprising direct-drive motor, coupling and active single-wheel; The rotating shaft of direct-drive motor one end is connected with last axle by coupling, and the rotating shaft of the direct-drive motor the other end is fixedlyed connected with the active single-wheel.
