Description

Vinyl film cutting device {A VINYL FILM CUTTING DEVICE}

The present invention relates to a vinyl film cutting device, and more particularly, to a cutting device structure to make the cutting operation of the vinyl film more effectively in the manufacturing process of the vinyl bag used as a fertilizer bag or feed bag.

In general, the manufacturing process of a vinyl bag used for packaging fertilizers or feeds is to fold the wound film fabric into two layers and heat-bond the folds, and then transfer the feed through a feed roller. After the vinyl film is cut at regular intervals in the process of continuously supplying the film fabric, manufacturing is made by heat-sealing finishing one side of the cut portion.

On the other hand, in the case of a conventional cutting device, the cutting blade is driven up and down, and in this case, the adhesion is often made between the film fabric at the cut portion by the pressing force of the cutting blade.

That is, when the cutting blade gradually becomes dull with use for a certain period of time, a high pressing force is applied to the film cutting portion, and the bonding phenomenon is caused by the pressing force between the two layers of the upper and lower films at the cutting portion.

Therefore, since the opening of the cutting site is not naturally made after cutting, the worker had to open the cutting site once more, which is inconvenient.

The present invention has been proposed to improve the above problems in the conventional film cutting operation, by providing a cutting device that can prevent the adhesion phenomenon between the upper and lower films in the cut portion of the two-ply film is more vinyl film cutting operation The goal is to be effective.

The present invention for achieving the above object, and a transport roller disposed in pairs in the up and down to transport the vinyl film supplied in a two-ply state on one side; A worktable on which a vinyl film transported by the transport roller is seated, and a cutting hole is formed on the upper surface to have a predetermined length in a width direction so that the cutting blade can reciprocate; A cutting blade configured to reciprocate in a horizontal direction along the cutout in a state where the cutout is provided at a predetermined height; A guide rail for guiding the reciprocating drive of the cutting blade; A pressurizing member provided to elevate from an upper portion of the incision hole to press and press the vinyl film when driving the cutting blade; A bottom groove formed on the bottom of the presser to secure a moving space of the cutting blade; Lifting drive means for manually lifting and lowering the presser bar; The drive belt is connected for the reciprocating drive of the cutting blade, the drive belt receives the forward / reverse drive force from the sub-motor;

In the present invention, the cutting edge of the vinyl film is cut in the form of reciprocating driving in the horizontal direction, so that the open state of the cutting portion can be stably maintained, thereby improving the cutting quality.

In particular, since the cutting operation is made in the pressurized state by the presser when cutting, it is possible to improve the quality of the cutting portion.

Figure 7 is an enlarged cross-sectional view of the lower end of the presser according to another embodiment of the present invention.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the characteristic structure of the film cutting device according to the present embodiment, the feed roller for forcibly conveying the vinyl film (S), which is supplied in the state of being wound in two layers on a winding roll (not shown) of one side to the cutting part side 10 is provided in pairs at the top and bottom, each of the transport roller 10, as shown in Figures 2, 3, 6, the guide spring 11 is provided at a position intersecting between the upper and lower, the vinyl film ( It was configured to achieve a stable transfer of S). Reference numeral M1 denotes a roller drive motor.

In addition, the worktable 20 to be cut is formed in the cutting hole 21 for securing a moving space of the cutting blade 30 has a predetermined length, the cutting blade 30 is the moving block 31 and the support block. It forms an integral coupling structure with (32), and the rail groove (32a) is formed on the bottom of the support block 32 is guided through the guide rail 40, the stable left and right sliding movement of the cutting blade (30) It could be done.

Drive belt 60 driven by the sub-motor 61 is connected to the movable block 31 to form a structure in which the drive belt is interlocked.

On the other hand, the pressing bar 50 for pressing and pressing the cutting portion of the vinyl film (S) during the cutting operation is configured to be lifted by the lifting drive means from the top, the lower edge of the presser 50, the cutting blade 30 The bottom groove 51 for preventing interference with the () is formed.

That is, the elevating drive means, the eccentric ring 59 is inserted into the outer circumferential side of the eccentric disc is rotated by receiving power from the drive motor (M) and on the upper portion of the eccentric ring 59 The second connecting rod 58 is connected, the second connecting rod 58 is connected to one side arm arm 56 is rotatably supported by the hinge shaft 57, and the other side of the arm stage 56 The first connecting rod 55 connected to the elevating plate 54 coupled to the lower end of the first connecting rod 55 and the pressure shaft 52 for connecting the elevating plate 54 and the presser 50. ) And an elastic spring 53 provided to surround the pressure shaft 52.

The effect of the driving of the film cutting device of the present invention constituting such a structure will be described.

First, while the conveying of the vinyl film S is performed by driving the conveying roller 10, when a certain length of conveying is made, the cutting operation by the cutting blade 30 is stopped while the conveying of the vinyl film S is stopped. Will be done.

That is, at this time, the presser bar 50 in the ascending state as shown in FIG. 2 is lowered as shown in FIG. 3 in accordance with the driving of the elevating driving means to press and fix the portion where the cutting of the vinyl film S is to be made. In this state, when the sub-motor 61 is driven in the forward direction, the movable block 31 and the support block 32 which are connected to the driving belt 60 along the guide rail 40 together with the cutting blade 30. The vinyl cutting is made by horizontally moving along the cutting hole 21 of the work table 20.

After the cutting operation is completed as described above, the press bar 50 is raised back to its original position, and the cut vinyl film is moved for the next bonding process, and the vinyl film is continuously driven by driving the transport roller 10. (S) is transferred back to the cutting work site.

When the vinyl film S is transferred to a predetermined length, the transport roller 10 is stopped and the presser 50 is lowered again. The 30 is moved horizontally again while the vinyl is cut.

Therefore, it can be seen that the continuous cutting operation of the vinyl can be achieved by the driving of the feed roller 10 and the lifting and lowering operation of the presser 50 and the left and right reciprocating movement of the cutting blade 30.

On the other hand, Figure 7 shows the lower structure of the presser 50 according to another embodiment of the present invention in cross section.

That is, the urethane layer 51a is formed on the bottom of the presser 50 as a coating to increase the frictional force with the vinyl film.

Since the urethane layer 51a is coated to prevent damage to the film surface when the vinyl film S is pressed, a more stable pressurized state can be maintained by increasing friction.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the vinyl cutting device of the present invention may be variously modified and implemented by those skilled in the art.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
