The invention provides a winding mechanism 10 which can improve the binding strength of a coil stock 20 to a product and improve the storage convenience of a packaging tape.
Referring to fig. 1 and 2, in some embodiments of the winding mechanism 10 of the present application, the winding mechanism 10 includes:
a winding shaft 11, the winding shaft 11 being used for winding a coil stock 20; and
a retraction unit 12, wherein the retraction unit 12 includes a first air column 121 and a second air column 122, the first air column 121 has elasticity and is of a hollow structure, one end of the first air column 121 is connected with the winding shaft 11, the second air column 122 has elasticity and is of a hollow structure, and the second air column 122 is communicated with the first air column 121;
the second air column 122 is fixed, and when the coil 20 is torn out to rotate the winding shaft 11, one end of the first air column 121 is driven to rotate so that the first air column 121 is twisted, so as to discharge the gas in the first air column 121 into the second air column 122.
The winding mechanism 10 provided by the present application can wind the coil 20 on the winding shaft 11 and pull the coil 20 from the winding shaft 11, and can be applied to the occasions where the coil 20 needs to be automatically recovered or the coil 20 needs to have a certain pre-tightening force, such as vehicle-mounted safety belts, and also can be used for packaging belts, specifically, the winding mechanism 10 provided by the present application is provided with the winding shaft 11 for winding the coil 20 and the retraction unit 12 for automatically retracting the coil 20; the material roll 20 may be a packaging bag or a safety belt, and the winding shaft 11 needs to be disposed on a mounting seat, which may be a component of the winding mechanism 10 itself, and the winding mechanism 10 is mounted and fixed on a use position through the mounting seat, which may also be a mounting structure on an application position, and the winding shaft 11 and the retraction unit 12 are mounted on the application position. The retraction unit 12 includes a first air column 121 and a second air column 122, wherein the first air column 121 and the second air column 122 are both elastic hollow structures, and can be made of rubber or silica gel, and the like, the first air column 121 is provided with a vent 1211 for communicating with the second air column 122, and one end of the first air column 121 is fixedly connected with the winding shaft 11. With such arrangement, when the roll material 20 is pulled out, the winding shaft 11 drives the first air column 121 to rotate so as to twist the first air column 121, the air in the first air column 121 is discharged to the second air column 122 through the vent 1211 and the vent 1221 of the second air column 122, so as to expand the second air column 122, at this time, the first air column 121 has a tendency of returning and restoring and driving the winding shaft 11 to reset and the roll material 20 to retract, and the second air column 122 also generates an elastic restoring force so as to have a tendency of discharging the air back to the first air column 121; when the free end of the coil 20 is fixed, the coil 20 is tightened under the action of the retraction force; when the free end of the coil stock 20 is loosened, the second gas column 122 contracts to return to the original shape under the action of elastic restoring force, so that the gas in the second gas column 122 can be discharged back to the first gas column 121, the first gas column 121 expands and reversely twists, the winding shaft 11 is driven to rotate to recycle the coil stock 20, the purpose of automatically recycling the coil stock 20 is achieved, and the coil stock 20 is prevented from being scattered and wound.
In some embodiments, the roll material 20 wound around the winding shaft 11 of the winding mechanism 10 of the present application is a packaging tape, and is used as a packaging tape device 100 for being applied in product packaging, such that the packaging tape device 100 is disposed on one side of a support seat for placing a product, and the free end of the roll material 20 is pulled out to cross over the support surface of the support seat and be connected to the other side of the support seat, at this time, the retraction unit 12 of the winding mechanism 10 can make the roll material 20 have a retraction tendency, but when the free end of the roll material 20 is fixed, the roll material 20 can be tightened to tightly press and bind the product, and when the free end of the roll material 20 is unwound, the roll material 20 can be automatically retracted, thereby preventing the roll material 20 from being scattered and wound, and improving convenience in use.
In some embodiments, if the roll 20 is pulled rapidly, the output of the air flow in the first air column 121 is blocked because the vent 1211 is not enough to rapidly discharge the air in the first air column 121 to the second air column 122, so as to block the rotation of the winding shaft 11 and prevent the roll 20 from being pulled out excessively; at this time, for example, when the roll 20 is a packaging tape for binding a product, when there is a risk of dropping the product when the product is inverted, it is possible to prevent the roll 20 from loosening and causing the product to drop from the winding mechanism 10, so as to reduce the risk of dropping and damaging the product and protect the product well.
In addition, if a mechanical structure such as the winding mechanism 10 of a volute spiral spring is adopted, the volute spiral spring may be permanently deformed to lose the original elastic force or the mechanical structure may be damaged due to fatigue after long-term use or when the force is applied too much, and the like, but in the present application, the gas column is adopted as the retraction unit 12, and the time of fatigue loss of the retraction unit 12 can be delayed by adopting the elastic gas column, so that the service life is prolonged, and the performance stability is ensured.
Therefore, it can be understood that the winding mechanism 10 of the present invention is provided with the winding shaft 11, which can be used for winding a packaging bag or the like as the roll 20, and is provided with the retraction mechanism to provide a reverse acting force to the winding shaft 11 when the roll 20 is pulled out, so that the roll 20 has a tendency of retracting, specifically, when the roll 20 is pulled out, the winding shaft 11 is driven to rotate, the winding shaft 11 drives the first air column 121 to rotate, so that the first air column 121 is twisted, the air in the first air column 121 is discharged to the second air column 122, so that the second air column 122 is expanded, so that the first air column 121 has a tendency of returning and driving the winding shaft 11 to reset and retract the roll 20, the second air column 122 also generates an elastic restoring force, and has a tendency of discharging the air back to the first air column 121, when the free end of the roll 20 is loosened, the second air column 122 contracts back to the original shape under the elastic restoring force, so that the air in the second air column 122 can be discharged back to the first air column 121, so that the first air column 121 is expanded and twisted, so that the roll 20 is wound, thereby improving the convenience of the roll 20.
When the roll 20 is used to press bound products and the free end of the roll 20 is fixed, the retraction unit 12 pulls the roll 20 to tighten the roll 20, so that the roll 20 compresses the products, and the binding strength of the products is improved.
