Automatic handle sticking equipment for vinyl bag {The auto handle sticking equipment for vinyl bag}

The present invention relates to a device for automatically attaching a handle to a plastic bag, and more particularly, by driving each part of a device through a single drive motor, while allowing each part to be organically driven while minimizing the number of driving power sources of each part of the device. And, by allowing the handle to be thermally bonded to the vinyl bag film fabric in a certain direction in a certain direction, and relates to a plastic bag handle automatic attachment device for facilitating alignment and lamination of the finished plastic bag.

In general, the manufacturing process of the plastic bag is supplied by folding the wound film fabric so as to make two layers, and attaching a separate handle film to the inner surface of both sides of the supplied film fabric at regular intervals to be bonded by heat bonding, and then transferred to the next step By thermally cutting both sides of the film with the handle, both sides are attached and cut at the same time to complete each plastic bag, and when the finished plastic bag is discharged, it is laminated by a certain amount and stored in a box.

The apparatus for attaching a handle for a plastic bag that proceeds to the manufacturing process as described above was required for the manual operation of the worker in the process of attaching the handle film to the plastic bag film fabric and when the finished plastic bag was discharged, stacking a predetermined quantity and storing it in a box. .

In particular, when attaching the handle film to the plastic bag film fabric, the handle film has a certain area, so when attaching to both sides of one side of the plastic bag film fabric, the round portion of the handle film is rolled to one side. It was a cumbersome problem to turn the handle to dry in the same direction.

If you do not twist the dried direction of the handle in a certain direction as described above, when the discharged lamination is completed, the direction of attachment of the handle is increased, the laminated plastic bag flows down, so that a large amount of lamination is impossible and a large amount can be packed even when stored in a box. There is a problem that can not be.

In addition, each part of the apparatus, such as a plastic bag film fabric supply unit, a handle film supply unit, a handle film cutting unit, a handle film conveying unit, and a handle film sealing unit, is operated by driving means having a separate power. There is a lot of problems in manufacturing the plastic bag, such as high consumption, the organic drive of each part is not made effectively, the handle attachment portion is not constant, the width of the plastic bag is also uneven.

The present invention has been made in view of the above problems, and by driving each part of the device through a single drive motor, while minimizing the number of driving power sources of each part of the device, each part is organically driven, while the plastic bag Technical object of the present invention is to provide a handle for automatically attaching a handle for a plastic bag to facilitate alignment and lamination of the finished plastic bag by allowing the handle to be heat-bonded to a film fabric in a predetermined direction.

The present invention for this purpose is a bevel gear and a power transmission spur gear for switching the transmission direction of the power, a rotating shaft coupled to the bevel gear for transmitting power, and an eccentric bearing and cam coupled to the rotating shaft to convert the rotational force into a linear driving force And a series of upper sealing driving units, lower sealing driving units, cutting driving units, cutting film conveying driving units, and film raw material supply driving units, each of which consists of a series of operations for transmitting driving force to the corresponding parts.
