The cam drive component by the bearing block 22 of 1 intermediate vertical inner hole of cabinet is arranged in, through 14 and of Box Cover The camshaft 19 of bearing block 22, the passive bevel gear 45 being sheathed on 19 cylindrical surface of camshaft consolidate passive 45 circumferential direction of bevel gear Due to the third flat key 42 on 19 cylindrical surface of camshaft, the washer 44, washer 44 is fixed that is arranged in below passive bevel gear 45 In on 19 lower end surface of camshaft the 4th screw 43, be sheathed on camshaft 19 and be arranged in above passive bevel gear 45 first every Set 7, is arranged in 22 inner hole jump-ring slot of bearing block the unilateral bearing 8 for being sheathed on camshaft 19 and 22 inner hole of bearing block being arranged in The second hole retaining ring 9, the cam 16, cam 16 is circumferentially fixed in 19 cylinder of camshaft that is sheathed on 19 middle position of camshaft The first flat key 21 on face, the second spacer 18 for being sheathed on 19 cylindrical surface of camshaft and being arranged in above cam 16, be sheathed on it is convex 19 cylindrical surface of wheel shaft and the second rolling bearing 17 being arranged in 14 inner hole of Box Cover are arranged in 19 cylindrical surface jump-ring slot of camshaft In the second shaft block ring 20, the second screw 23 that bearing block 22 is fixed in cabinet 1, Box Cover 14 be fixed on cabinet 1 First screw 13 of top surface is constituted, driving bevel gear 41 and passive 45 phase configuration of bevel gear, the head end and cam 16 of frizzen Phase configuration.

The working principle of the high low speed conversion set of the utility model belt wheel is as follows:

The quilt installed in the active synchronization belt wheel 48 and centre tooth wheel body 46 installed on 52 axis of motor and gearbox combination Dynamic synchronous pulley 6 constitutes synchronous belt drive mechanism by synchronous belt 49, its general power is constant.Centre tooth wheel body 46 is inputted Power divide two-way, be all the way belt wheel 26 is passed to by planetary drive, and another way pass through cam drive component Pass to cam 16.Because what is installed on camshaft 19 is unilateral bearing, the rotation direction of belt wheel 26 and cam 16 is determining. When automatic electric strapper is in drawstring state, pulling force suffered by belt wheel 26 is little, and cam 16 is in several disc springs Under 12 spring pressure, the second operating position 54 cannot be rotated to from the first operating position 53, cam is motionless, pinion frame 47 Also slack, so the high revolving speed that centre tooth wheel body 46 inputs is entirely delivered to belt wheel by planetary gear 30 and internal tooth 27 26.When strapping is drawn out banding tank systems and begins around packing material, power suffered by belt wheel 26 is become larger, belt wheel 26 Revolving speed gradually becomes smaller, and at this moment, cam 16 overcomes the spring pressure of several disc springs 12, rotates to second from the first operating position 53 Operating position 54 simultaneously stops, while opening frizzen 15, and 15 trigger sensor 10 of frizzen, sensor promotes motor and speed change Speed change gear in case 52 combines is lower speed, and just to slowly run, automatic electric strapper is converted to belt wheel 26 by drawstring movement Puller strap movement.Same reason, cam 16 cannot revolve under the spring pressure of several disc springs 12 from the second operating position 54 Third operating position 55 is gone to, the slow-speed of revolution that centre tooth wheel body 46 inputs is digested by belt wheel 26 completely.When automatic electric is tied up Machine tenses under carrier state, and strapping is close to packing material, and when belt wheel does not turn, cam 16 rotates to third work from the second operating position 54 Make position 55, carries out next movement.

Specifically used method is as follows:

Firstly, strapping 36 is injected part between belt wheel 26 and pad wheel group 37, because there is pressure always on pad wheel assembly 37 Clamp force, so belt wheel 26 can complete that band, drawstring, puller strap etc. is sent to act.Strapping 36 is in motor and gearbox combination 52 Drive under pass through automatic electric strapper tie disc, belt machine, machine head assembly, banding tank systems it is contour speed around packing material one Circle.It send band (to be controlled with encoder) after in place, clamps strapping, high speed drawstring, strapping is drawn out banding tank systems and opens Begin to surround packing material.When strapping has been centered around packing material, 26 revolving speed of belt wheel slows down up to stopping, at this moment, cam 16 The spring pressure for overcoming several disc springs 12 rotates to the second operating position 54 from the first operating position 53 and stops, pushing up simultaneously Frizzen 15,15 trigger sensor 10 of frizzen are opened, the speed change gear in sensor promotes motor and gearbox 52 to combine becomes Low speed, just to slowly run, automatic electric strapper is converted to puller strap by drawstring movement and acts belt wheel 26.Automatic electric is tied up Machine tenses under carrier state, and strapping is close to packing material, and when belt wheel does not turn, cam 16 rotates to third work from the second operating position 54 Make position 55, the movement such as is sealed, cut off.

The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
