Description

Joining and cutting machine for vinyl sheets {a joining and cutting machine for vinyl sheet}

The present invention relates to a device for bonding and cutting vinyl, and more particularly, to printing various patterns, characters, etc. on various vinyl sheets, and then cutting them in a constant size and shape. The present invention relates to a joining and cutting device of a vinyl sheet having a cutting device incorporating a heating cutter at one end of a rotating cylinder so as to be repeatedly executed.

In general, the cutting device of vinyl is to cut to an appropriate size when the vinyl sheet is transported, the heating wire is provided at the end of the cutting device to be joined and cut while the whole is swung up and down.

The conventional vinyl bonding and cutting device is shown in Figure 1, looking at its configuration, the feeding roller 611 and the feeding roller 611 for releasing the vinyl sheet 500 to hold the vinyl sheet 500, and feeding When the vinyl sheet 500 moderately released by the roller 611 is pulled forward by the pinch roller 620, the length is adjusted by the lifting roller 612 and the guide roller 613 to adjust the length, The heater 630 and the cutter 640 that are in motion are interlocked by the pinch roller 620, the stroke 621, and the half moon gear 622, and the half moon gear 622 is pulled forward, and the half moon gear 622 is moved. While reversing, the movement of the vinyl sheet 500 is stopped, and at the same time, the bonding and cutting are performed, and the same operation is repeated by the repeated operation of the pinch roller 620 and the half moon gear 622.

In the conventional vinyl cutting device having the above-described configuration, the heater and the cutter are dualized, and thus a problem in which the point to be cut and the point to be cut does not coincide due to the difference in resistance of the vinyl sheet frequently occurs, and also depending on the state of the vinyl sheet. Due to the continuous fluctuation of the bonding and cutting points, more defects occur in the case of the printed vinyl sheet.

In addition, the heater and the cutter all slide up and down, causing frequent failures, and the force of pressing the vinyl during cutting is not great, making it difficult to maintain the vinyl sheet in a parallel state, thereby causing cutting defects. There is another problem that occurs frequently.

In addition, since the transport means and the cutting means of the vinyl sheet are to be provided respectively, the manufacturing cost of the facility is very high, there is another problem that it is difficult to drive the transport means and the cutting means to interlock at a constant speed.

The present invention has been invented to solve the above problems, by inserting a heating cutter on one end of the cylindrical cylinder to enable the transfer and cutting as a single facility, the transfer means and the cutting means is precisely interlocked at a constant speed It aims at improving the evenness of a product.

In addition, more precise and accurate cutting is possible by using a cutter heated by a heating wire, and when cutting, the vinyl sheet is firmly pressed by a cam plate that slides up and down according to the rotation of the cam. It is another purpose to remain accurate.

In addition, it is another object to easily adjust the width of the vinyl sheet to be cut by replacing the mounting of the cylinder of various diameters.
