Description

Technical Field

[0002] The toothed belt transmission mechanism is a belt transportation method that uses the meshing transmission between the pulley and the belt. Compared with the general flat belt transmission, the toothed belt transmission has the following advantages: there is no relative sliding between the pulley and the belt, which can achieve synchronous transmission, high transmission efficiency, and a wide transmission power range.

[0032] Here’s how it works:

[0033] When the toothed belt transmission mechanism is to be used, the driving gear 2 can be rotated by an external driving device. As the driving gear 2 rotates, the toothed belt 3 meshed with the outer side of the driving gear 2 can move accordingly to achieve synchronous rotation of the driven gear 4 connected to the other side. In this way, the toothed belt 3 as a whole can move stably to meet the required transmission requirements.

[0034] During the movement of the toothed belt 3, it is easy for external foreign matter to adhere to it, causing damage to the toothed belt transmission mechanism. For this reason, a cleaning device 5 is provided in the middle of the connecting plate 1 to realize the purging and cleaning of the tooth gap of the active gear 2. First, the inner tube 547 provided inside the blowing component 54 is connected to the external negative pressure device, so that the gas generated by the external negative pressure device can enter the outer tube 546 along the inner tube 547 and then enter the gas collecting shell 548 along the outer tube 546. Finally, with the cooperation of the multiple groups of inclined nozzles 549 provided at the bottom of the gas collecting shell 548, an inclined purging activity can be realized, so that the foreign matter attached to the tooth gap of the active gear 2 can enter the inlet groove 551 provided on the front side of the connecting shell 52 under the purging effect, and then be collected into the collection box 552 along the inlet groove 551, so as to realize the rapid air purging and cleaning of the outer side of the toothed belt 3, and realize the cleaning of the toothed belt 3 without damaging the toothed belt 3. The servo motor 541 is installed at the upper end of the rear side of the connecting shell 52 to make the servo motor 541 realize the rotation of the turntable 542 connected to the bottom. As the turntable 542 rotates, the transmission shaft 543 inserted into the turntable 542 opens the long groove provided in the connecting strip 544 connected to the bottom to realize the left and right reciprocating movement of the connecting strip 544 as a whole. In this way, the fastening plates 545 connected to both sides of the lower end of the connecting strip 544 can realize the left and right reciprocating telescopic movement of the outer tube 546, and change the position of the gas collecting shell 548 back and forth, so that the nozzle 549 can realize efficient air purging and cleaning of foreign matter. Since the nozzle 549 is installed in an inclined state, it can still maintain the forward purging and cleaning effect during the rightward reset process of the gas collecting shell 548, thereby achieving efficient air purging and cleaning of foreign matter attached to the outer side of the toothed belt 3, thereby ensuring the overall service life of the toothed belt transmission mechanism.

[0035] When the foreign matter swept by the air is collected into the collection box 552 along the inlet groove 551, and the collected foreign matter needs to be processed, the handle 553 provided at the bottom of the collection box 552 can be grasped to pull down the collection box 552 as a whole, thereby causing the docking rod 554 and the convex ball 555 inserted into the front side of the connecting shell 52 to move outward, and the convex ball 555 will quickly release the elastic clamping effect with the spring clip 556, so that the collection box 552 as a whole can be quickly disassembled, realizing To deal with the foreign matter collected inside, when reinstalling the collection box 552, you only need to align the docking rod 554 with the plug-in position, insert the docking rod 554 and the convex ball 555 into the front side of the connecting shell 52, and when the convex ball 555 is connected with the spring clip 556, the convex ball 555 will be squeezed into the spring clip 556, and the spring clip 556 will cooperate with its own elastic effect to achieve elastic locking cooperation with the convex ball 555 as a whole. In this way, the collection box 552 can be installed and used again.
