Description

[Detailed description of the invention] Heat sealing device Technical field The present invention relates to a device for thermally bonding a display mark to textiles. relates to a heat sealing device used to apply text or logos to clothing.

Background technology There are two types of conventional heat sealing equipment. These two types are clam forging. type and swing-away type. Both types of devices have an upper pressure plate and a lower pressure plate, and The pressure plates can be moved relative to each other and are therefore aligned in the closed position. Heat source is on one side Included in the pressure plate. Heat-fixed display marks such as letters, numbers, and identification logos To be applied to T-shirts, long-sleeved sweaters or other clothing, the markings must be is placed on the fabric between the pressure plates, pressure is applied to each pressure plate, and at the same time the heat-fixed display body is Make sure to provide enough heat to bond to the fabric. After an appropriate period of time, the lateral pressure plate Separate the fabric and take out the fabric with the display mark stuck to it.

These two types of equipment are further classified as manual, semi-automatic, and automatic equipment. It will be done. Both devices require an operator. The manual device controls the side pressure plate pressure, temperature, The operator is required to adjust the time when the pressure and temperature are applied to the visible mark and the fabric. Ru. Semi-automatic equipment requires manual alignment of the lateral pressure plate, but after a predetermined time The side pressure plate opens automatically. The automatic device provides the force to move the lateral pressure plate to the alignment position. Compressed air or a motor is required to supply the air, and after alignment, pressure is applied and then After a period of time, separate the pressure plates. In these devices, the pressure on the side pressure plate during alignment is controlled by the operator. or the force of the mechanical means used to effect the alignment. side pressure plate Manual or semi-automatic devices are known that have means for controlling and regulating the pressure between not present. Unable to control the pressure between the lateral pressure plates, the operator must It is impossible to know whether the pressure applied is appropriate and the same set of letters and fabrics If it is supplied for each actuation, repetition will occur. The same display mark It cannot be applied repeatedly to the same fabric. As often happens, A good bond between the marking and the fabric will not be achieved if inappropriate pressure is applied. A difficult situation arises.

The time and heat that the lateral pressure plates are overlapped (aligned) also makes it easier to write letters on clothing. It is equally important for good adhesion. With both manual and semi-automatic equipment The matching time is also initiated by the operator, and very often the timer is set on a clock or wristwatch. However, other types of timers can also be employed.

Since the alignment time is started by the human operator, similar characters between the lateral pressure plates and There are variations in the application time of the pressure applied to the fabric, which can lead to poor bonding. Cause.

Additionally, manual or semi-automatic devices can control pressure, time and temperature at the same time. The device is unknown. These variables such as pressure, time, and temperature are interrelated. However, there is no known heat sealing device that can simultaneously control these variables and perform an effective bonding process. Not yet.
