SUMMERY OF THE UTILITY MODEL

For solving the limited shortcoming of trafficability characteristic when crawler-type automatic vending machine goods transmit between the track among the prior art, the utility model aims to provide a track transmission transition mechanism.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

a track transmission transition mechanism is structurally characterized by comprising a transition roll shaft and a transmission mechanism; the transition roll shaft is fixedly arranged at one end or two ends of the transmission crawler; the driving roll shaft of the transmission crawler is in transmission connection with the transition roll shaft through a transmission mechanism, and the rotation directions of the transition roll shaft and the driving roll shaft are the same.

Furthermore, the axial outer wheel of the transition roller shaft is internally tangent to the upper surface of the transmission track so as to ensure the stability of goods transportation.

Furthermore, two ends of the transition roll shaft are respectively arranged on the brackets at two sides of the transmission crawler belt

Further, drive mechanism includes action wheel and follows driving wheel, the action wheel sets firmly in drive roller axle tip, follow driving wheel and set firmly in transition roller axle tip.

Further, the driving wheel is connected with the driven wheel through a gear, a belt or a chain.

Furthermore, drive mechanism still includes the idler, and the idler is located between action wheel and the follow driving wheel and fixes at the support side of transmission track, and action wheel and follow driving wheel all mesh with the idler mutually.

Further, a transmission ratio is arranged between the driving wheel and the driven wheel, and the transmission ratio enables the rotation linear speed of the transition roller shaft to be equal to or slightly larger than the translation speed of the transmission crawler.

Compared with the prior art, the utility model discloses following beneficial effect has:

first, through increasing the transition roller, can reduce the clearance between the transmission track by very big degree, can effectively guarantee that the goods of small-size also can pass through smoothly, and do not blocked.

Second, through increasing the transition roller, reduce the clearance between the transmission crawler greatly for the goods is difficult to take place the slope in transmission process, has effectively improved the stability that the goods passed through, especially to the goods of focus height on the high side, can effectively prevent that the goods from empting.

Thirdly, through drive mechanism, can make the transition roller also can obtain power, through setting up suitable drive ratio moreover, make the rotational linear velocity of transition roller equal to or slightly be greater than the translation speed of transmission track, this not only can prevent effectively that the goods from blocking because of the power is not enough in the transmission course, can also guarantee the stationarity of goods in the transmission course.

Detailed Description

As shown in fig. 1 to 3, the track transmission transition mechanism comprises a transition roller shaft 1 and a transmission mechanism 2. Transition roller 1 sets firmly in the place ahead of transmission track 3, and the axial foreign steamer of transition roller 1 is tangent mutually with transmission track 3 upper surface, and the forefront of transition roller 1 and the forefront parallel and level of transmission track 3. Two ends of the transition roll shaft 1 are respectively fixed on the supports at two sides of the transmission crawler 3 and can freely roll and rotate along the axis of the transition roll shaft. The transmission mechanism 2 is arranged on one side of the transmission crawler 3, the driving roller shaft 31 of the transmission crawler 3 is in transmission connection with the transition roller shaft 1 through the transmission mechanism 2, and the rotation direction of the transition roller shaft 1 is the same as that of the driving roller shaft 31. The transmission mechanism 2 can transmit the power of the drive roller shaft 31 to the transition roller shaft 1.

The transmission mechanism 2 comprises a driving wheel 21 and a driven wheel 22, wherein the driving wheel 21 is fixedly arranged at the end part of the driving roller shaft 31 and can be driven by the driving roller shaft 31 to rotate together. The driven wheel 22 is fixedly arranged at the end part of the transition roll shaft 1 and can drive the transition roll shaft 1 to rotate together. The driving wheel 21 and the driven wheel 22 can be connected by means of, but not limited to, gears, belts or chains. In this embodiment, the transmission mechanism 2 further includes an idle wheel 23, the idle wheel 23 is disposed between the driving wheel 21 and the driven wheel 22, and both the driving wheel 21 and the driven wheel 22 are meshed with the idle wheel 23. The idler wheel 23 is fixed to the side of the frame of the conveyor track 3. The idler 23 can transmit the rotation of the driving wheel 21 to the driven wheel 22, and make the driving wheel 21 and the driven wheel 22 have the same moving direction, thereby ensuring that the moving direction of the transition roller shaft 1 is always consistent with the belt moving direction of the transmission crawler 3.
