Description

Vinyl Envelope Manufacture Apparatus

The present invention mainly relates to a vinyl bag manufacturing apparatus for putting goods in a variety of businesses, such as large stores or supermarkets, and more particularly relates to a plastic bag manufacturing apparatus of one type of opening and the other closed.

As is well known, various retailers use a rather large plastic packing stand to accommodate products of various specifications.

1 shows a conventional manufacturing apparatus for producing such a rather large plastic bag. As can be seen from the prior art, the welding degree 100 and the cutting degree 101 which slide up and down in order to form a welding line and a cutting line at regular intervals on a large plastic packaging stand were used. Accordingly, the welded sheet 100 and the cut sheet 101 are lowered and welded or cut at the moment of being transported, and the plastic paper must be momentarily stopped. For this purpose, a separate sophisticated braking device must be installed and operated to raise the production cost. Since the process to be stopped and moved regularly must be repeated, there is a problem that the limitation in improving the work speed is inevitable and the productivity is low.

Therefore, by adopting the method of replacing the welding degree 100 and the cutting degree 101 with a rotary roller, it is easy to think of a method for continuous welding and cutting to be made, but the plastic wrap used in the merchandise store has a large standard. It is difficult to apply the rotary roller method because the size of the roller is also increased together.

The purpose of the present invention is to solve this problem, in order to manufacture the plastic packaging to be manufactured while moving continuously without stopping at the moment of transporting the base of the plastic packaging, plastic packaging without the need to use large rollers A large manufacturing apparatus is provided.

In order to achieve the above object, the present invention allows the welding line and the cutting line to be formed in the process of transporting the plastic paper wound on the feed roll to the take-up roll, and the welding degree to which the heater is attached to form the welding line and the cutting line, and the cutting unit A device for manufacturing a plastic wrapper, in which cuts arranged at regular intervals are fixed to a rotating shaft rotated by one or more motors.

Accordingly, the present invention enables the welding line and the cutting line to be continuously formed without using the welding roller or the cutting roller of a large standard, thereby greatly improving the productivity and reducing the burden of facility costs.

This invention is described in more detail with reference to the accompanying drawings as follows.

2 to 4 show the overall configuration of the apparatus for producing a plastic bag according to the present invention. As can be seen from this, the present invention provides a supply roll (1) for supplying a vinyl wrapping paper base, and a winding roll (4) for winding a completed vinyl packaging table on which a welding line (2) and a cutting line (3) are formed. and,

The guide roll 5 for guiding the movement between these feed rolls 1 and the take-up rolls 4 and maintaining proper tension, and for adjusting the distance between the welding line 2 and the cutting line 3, In the well-known plastic bag manufacturing apparatus provided with the lifting roll 6 and the welding line forming means 7, and the cutting line forming means 8 which position is adjusted downward,

Electric welding line forming welding line forming means (7) and cutting line forming means (8) are rotated by one or more motors (9) power and two rotary shafts (10) installed at the position where the plastic wrapper passes through, A welding degree 12 having a heater 11 that generates heat at a temperature and fixed to a rotating shaft 10 on one side, and a cutting diagram 13 fixed to the rotating side on another side and having a plurality of cutting parts 14. And a pad 15 for welding the electric welding degree 12 and the cutting degree 13,

Reference numeral 16 denotes a handle, 17 a bevel gear, and 18 a screw rod.

The present invention as described above is wound around the heater (11) and the motor (9), such that the plastic wrapper base is wound around the take-up roll (4) via the guide roll (5) and the lifting roll (6) in the feed roll (1) Apply power.

Accordingly, the base of the plastic wrapper starts to be transferred by the power of the motor 9 and moves from the feed roll 1 to the take-up roll 4. In this process, the present invention is the first welding degree 12 heated to a certain temperature by the heater 11 is to heat the plastic wrapper base, the welding degree 12 is so that the tip is not sharpened while rotating Intensive heat is applied to one side of the plastic packaging table by the pad 15 fixed at the welded position so that the two sheets are welded to each other so that the welding line 2 is formed. After the welding line 2 is formed in this manner, the base of the plastic wrapper passes through the lifting rolls 6, and then reaches the cutting degree 13. At this time, the cutting portion 13 rotates and the cutting portion 14 is rotated. When the cutting edge of the blade reaches the position to be treated with the pad 15, the sharp cutting portion 14 of the tip portion forms a cutting line 3 on a portion of the base of the plastic wrapper, and then passes through the guide roll 5 To be wound on the take-up roll (4) with an appropriate tension.

In the series of processes for producing such a plastic wrapper, the present invention is a welding line (2) and the cutting line (3) is formed on the vinyl at a continuous and fast speed without particular interruption.

In this process, the present invention is proportional to the distance between the weld line 12 and the cutting line 13 to the center of the rotation axis 10 and the weld line 2 and the cutting line 3 to be rotated.

Therefore, it is a matter of course to design by adjusting the distance from the tip of the welding degree 12 and the cutting degree 13 to the center of the rotary shaft 10 according to the use.

In addition, the distance between the welding line 2 and the cutting line 3 should be adjusted according to the length of the welding line 2. To this end, the present invention provides a bevel gear 17 and a bevel gear 17 which are rotated by the handle 16 so that the position of the lifting roll 6 can be easily adjusted by the rotation of the handle 16. The screw rod 18 which rotates in a fixed position, and the lifting roll 6 fitted to the screw rod 18 and elevating according to the rotation of the screw rod 18 can be provided.

The present invention is the screw rod 18 is rotated as the handle 16 is rotated, according to the rotation direction and the rotational speed of the screw rod 18 rises or falls 6, corresponding to the rotational speed Ascending or descending by the position.

Thereby, the space | interval of the welding line 2 and the cutting line 3 adjacent to it can be adjusted suitably.

In this way, the finished plastic wrapper is rolled up in a rolled state as shown in FIG. 5 to grasp and pull the cut line 3, and one side is opened and the other side is a closed plastic wrapper so that the product can be used.

Thus, in the present invention, the welding line 2 and the cutting line 3 are formed in the process of continuously winding the vinyl wrapper toward the take-up roll 4 from the feed roll 1 in manufacturing the plastic wrapper. Since it is produced without any braking and stopping process, the productivity is greatly improved, but large welding rolls or cutting rolls are unnecessary, so that the production cost is reduced, thereby reducing the burden of facility costs.
