After the supportingmember 144 being assembled to thesecond part 114, the supportingmember 144 moves along the axis C1 relative to thesecond part 114 but not being released from thesecond part 144 because of a hook structure existed at an end of eacharm 144a. Besides, a plurality of ribs existed on thelip portion 144b to reduce contact area between thefriction ring 142a and thelip portion 144b, such that thefriction ring 142a rotates relative to the supportingmember 144 about the axis C1. - Therefore, the
first spring 146 is pressed and deformed by the supportingmember 144 and thesecond part 114 when thefirst part 112, thesecond part 114 and thefriction module 140 are assembled to each other, such that a pressing force of thefirst spring 146 is provided onto the supportingmember 144 and thefriction ring 142a so as to lean thefriction rollers 142b onto a side surface of thefriction pad 134 via thesub openings 112a respectively. - It is worth to mention that the
friction rollers 142b and thefriction pad 134 are respectively made of friction material such as wool felt, rubber etc., such that a friction force is generated when thefirst spring 146 forces thefriction ring 142a to lean thefriction rollers 142b onto thefriction pad 134. Therefore, when theshaft body 132 is rotated along with thefilm roll 200, the rollingshaft module 130 drives thefriction ring 142a to rotate via the friction force generated between thefriction pad 134 and the friction rollers, wherein the rollingshaft module 130 and thefriction ring 142a are rotated in a same direction while thefilm roll 200 being dragged and rotated by thedriving mechanism 120. -
FIG. 3 andFIG. 5 respectively depict a part of the inflatable cushion packaging machine ofFIG. 2 in different states.FIG. 4 depicts the inflatable cushion packaging machine in another view ofFIG. 3 , wherein thehousing 110 is disassembled inFIG.4 to identify necessary members therein.FIG. 6 depicts the inflatable cushion packaging machine in another view ofFIG. 5 , wherein thehousing 110 is disassembled inFIG. 6 to identify necessary members therein. Please referring toFIGs. 3-6 of the embodiment, thefriction module 140 further comprises at least one second spring 148(twosecond springs 148 are depicted but not limited thereto) connected between thefirst part 112 and ahook 142c located at an edge of thefriction ring 142a, wherein thesecond spring 148 is deformed while thefriction ring 142a being rotated with theshaft body 132 and thefriction pad 134, and a restoring force of thesecond spring 148 pulls back thefriction ring 142a while theshaft body 132 not being dragged and rotated by thedriving mechanism 120. Please referring toFIG. 2 again, each of thesub openings 112a extends along an arc path, and thefriction rollers 142b protruded out of thesub openings 112a move along the arc path while thefriction ring 142a being rotated along with theshaft body 132, which also means the movement of thefriction rollers 142b is guided by thesub openings 112a. As depicted inFIG. 5 andFIG. 6 , a driving force of thedriving mechanism 120 provided to drag thefilm roll 200 is greater than the friction force generated between thefriction rollers 142b and thefriction pad 134, such that thefriction rollers 142b and thefriction ring 142a are both still acted for rotating as well. When once thedriving mechanism 120 is stopped, thefilm roll 200, the rollingshaft module 130, thefriction roller 142b and thefriction ring 142a are still in the movement of rotation because of the inertia of the driving force. At this time, the friction force between thefriction roller 142b and thefriction pad 134, and the restoring force of thesecond spring 148 both act as a braking system to stop the rollingshaft module 130 from rotating, wherein the second springs rotate the friction ring in an opposite direction relative to the shaft body and the friction pad thereon. Therefore, it is beneficial to keep the material sheets of thefilm roll 200 between the rollingshaft module 130 and thedriving mechanism 120 in a stretched manner so as to prevent the material sheets from being folded, stocked and blocked, and it is also beneficial to reduce working time of the inflatablecushion packaging machine 100. - In view of the foregoing, the inflatable cushion packaging machine has a friction module assembled to the housing for reducing the impact of rotational inertia of the film roll and the rolling shaft module while the driving mechanism is stopped. The friction module includes a friction ring forced by a first spring to lean the friction rollers against the friction pad of the rolling shaft module to generate the friction force therebetween, and the friction module further includes the second spring for pulling back the friction ring via the restoring force thereof in a rotating direction opposite to the rolling shaft module (and the film roll). Therefore, the friction module plays a role of a braking structure corresponding to the rolling shaft module so as to reduce the working time of the machine wasted in a process of waiting for the rolling shaft module being stopped.
