A rotatable rod is rotatably connected between the two sidewalls includes a right-handed threaded section and a left-handed threaded section. The two blocks has two respective threaded passages which are respectively connected to the right-handed threaded section and the left-handed threaded section so that when rotating the rotatable rod, the two blocks are moved in opposite directions. Two wheels are respectively connected to the two blocks so as to contact thermo shrinkable film mounted on a shaft. An adjustable mechanism includes a driving wheel connected to an end of the rotatable rod and can be positioned by a positioning unit received in one of the two sidewalls.
Description
- The present invention relates to an adjustable mechanism for micro-adjusting the wheels for transmitting the thermo shrinkable film of different thickness.
- A conventional thermo shrinkable film machine generally includes a transmission wheel with a hole defined centrically therethrough and a shaft rotatably extends through the hole in the transmission wheel with a small gap defined between the inner periphery of the hole and the shaft. Two upper pressing wheels are located around the shaft so as to provide proper pressure on the thermo shrinkable film and to move film downward along the shaft. A cutting device is located beneath the transmission wheel so as to cut the film at pre-decided length. A positioning device is located beneath the transmission wheel and includes two lower pressing wheels which guide the film to be mounted to containers or cans. Two flexible plates are used to stop lower edge of the film which is not yet sent to mount on the containers or cans. A common problem is that the thickness of the film may vary due to the different manufacturers and the upper pressing and lower pressing wheels have to be adjusted accordingly by manual efforts and this spends a lot of time.
- The present invention intends to provide an adjustable mechanism for micro adjusting the pressing wheels for the shrinkable film of different thickness.
- The present invention relates to a thermo shrinkable film machine which comprises a base with two sidewalls and two rails are connected between the two sidewalls. A rotatable rod is rotatably connected between the two sidewalls and located between the two rails. The rotatable rod includes a right-handed threaded section and a left-handed threaded section. Two blocks are movably mounted to the two rails and have two respective threaded passages so as to be engaged with the right-handed threaded section and the left-handed threaded section respectively. Two wheels are respectively connected to the two blocks so as to contact thermo shrinkable film mounted on a shaft. A positioning unit received in one of the two sidewalls and a driving wheel which is connected to an end of the rotatable rod. The driving wheel is positioned by the positioning unit.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
-
FIG. 1 is an exploded view to show the thermo shrinkable film machine and the adjustable mechanism of the present invention; -
FIG. 2 is a perspective view to show the thermo shrinkable film machine and the adjustable mechanism of the present invention; -
FIG. 3 is a cross sectional view to show that the bead is engaged with one of the notches in the driving wheel; -
FIG. 4 shows when rotating the driving wheel, the bead is removed from the notch of the driving wheel; -
FIG. 5 shows the bead is engaged with another notch of the driving wheel so as to adopt the wheels on the two blocks to the thicker film; -
FIG. 6 is another embodiment of the adjustable mechanism of the present invention, and -
FIG. 7 is yet another embodiment of the adjustable mechanism of the present invention. - Referring to FIGS. 1 to 3, the thermo
shrinkable film machine 2 of the present invention comprises a base with twosidewalls base 20 and atransmission wheel 60 for driving ashaft 6 is rotatably engaged with a recess in a side of thebase 20. Tworails sidewalls rotatable rod 3 is rotatably connected between the twosidewalls rails rotatable rod 3 includes a right-handed threadedsection 31 and a left-handed threadedsection 32. Twoblocks rails section 31 and the left-handed threadedsection 32 are respectively threadedly engaged with the two respective threaded passages such that when rotating therotatable rod 3, the twoblocks rails wheels blocks shrinkable film 7 mounted on theshaft 6. - An adjustable mechanism includes a
positioning unit 5 received in ahole 210 in thesidewall 21 and adriving wheel 4 has a rectangular hole through which a rectangular section on an end of therotatable rod 3 extends. Thedriving wheel 4 has a plurality ofnotches 40 defined in a side thereof. Thepositioning unit 5 includes abead 50 and aspring 51 which biases thebead 50. Thebead 50 and thespring 51 are received in asleeve 52 which has a smaller opening in one end of thesleeve 52 so as to prevent thebead 50 from dropping from thesleeve 52. Thebead 50 is engaged with one of thenotches 40 of thedriving wheel 4. - Referring to
FIGS. 4 and 5 , when thefilm 7 to be used is thicker than the previous one, the user may rotating thedriving wheel 4 to move the twoblocks bead 50 is engaged with anothernotch 40. The small gap of adjustment between thewheels film 7 allows thewheels thicker film 7 properly. - Referring to
FIG. 6 which shows another embodiment of the present invention wherein thedriving wheel 4 includes an insertion which is rotatably extends through thesidewall 21, and a plurality ofnotches 40 are defined in an outer periphery of the insertion.
