Abstract
A driving mechanism for a labeling machine aims to drive a transmission assembly thereof from a power source through a linking member such as a belt. The transmission assembly concurrently drives rotation of an axle assembly so that a feeding wheel coupled on an axle can draw and convey a roll of film. A belt with teeth formed on two sides serves as a transmission member of the transmission assembly to transmit rotation to two axle wheels. The transmission assembly can transmit rotation accurately, rapidly and concurrently. The structure of the transmission assembly is simplified. Wearing can be reduced. Repair and maintenance also are easier.
Claims8
A driving mechanism for a labeling machine, comprising a driving wheel connecting to a power source of an electric motor, a base, a linking assembly, a transmission assembly, an axle assembly and an adjustment assembly, wherein:
- the base is fastened to a chassis of the labeling machine through an angular post and includes at least one sliding track which has two sliders located thereon corresponding to each other;
- the linking assembly is located on and runs through the base and at least includes an actuation shaft, an actuation wheel, a linking wheel and a linking member, the actuation wheel and the linking wheel being fixedly coupled on one end of the actuation shaft, the actuation shaft having other end running through the base, the linking member is annular and engaged with the actuation wheel and the driving wheel;
- the transmission assembly is mounted onto the base and connected to the linking assembly, and at least includes a transmission wheel, a transmission member, two sets of axle wheels corresponding to each other and two sets of pushing wheels corresponding to each other;
- the transmission wheel being fixedly coupled on the other end of the actuation shaft which runs through the base and turnable concurrently with the actuation wheel and the linking wheel, the transmission member is annular and coupled and engaged with the transmission wheel, two sets of axle wheels and two sets of pushing wheels are located respectively on the two sets of sliders, the axle wheels and the pushing wheels are spaced from each other at a selected gap to allow the transmission member to pass through, the transmission member is engaged with the pushing wheels and the axle wheels, the transmission wheel and the axle wheels and the pushing wheels are bridged by the transmission member so that the axle wheels on the two sliders are turnable concurrently;
- the axle assembly is located on the axle wheels of the transmission assembly;
- and
- the adjustment assembly is located on the base and engages with the transmission member of the transmission assembly and has an idler pulley to adjust the tension of the transmission member.
