Description

The present invention relates to a heat soluble bonding machine bent surface of the heat-welding elastic material cord.

Thermal solvent deposition of the bent face of the heat-welding elastic material straps conventionally at all thermal solvent deposition of the bent surface through a thermal welding elastic material strap for fitting materials manual tongs scissors and iron for soldering It is made using a modified machine, but it requires a strong grip on the right hand, and it seems that there is some difficulty with low uniformity. Therefore the appearance of the machine is desired, such as autothermal soluble adhesive robot.
By simply pushing the push button switch according to the present invention, there will be no strong grip on the right hand, and it will be possible to spend a day with comfortable work with good uniformity.

Conventional manual work requires strong grip strength and practice time, and is considered to be technically very difficult manual work. However, by manually passing a heat-welding elastic material string through the metal bracket, is placed in a simple operation of just pressing a push-button switch, strong grip strength even without the need machine is bent surface of the finished possible heat-welding elastic material string of high-quality products that are accurate and uniformity heat soluble It is something that is going to be solved by the landing machine.

A pair of left and right molds that are placed on and interlocked with a horizontal slide that opens and closes to the left and right, and a pair of left and right side opening and closing side cams that open and close the horizontal slide;
A heating head capable of moving up and down and an outer peripheral cam for up and down movement of the heating head are provided at the center of the pair of left and right molds,
When the end faces of the pair of left and right molds are open, the heating head descends a predetermined distance from above the heat-welding elastic material string placed at a predetermined position across the pair of left and right molds, and after the lowering The heat-weldable elastic material string is bent in the stopped state, and the melt-pressing is started around the heating head together with the heat-weldable elastic material string with the pair of left and right molds, and after the melt-pressing is completed. The heating head is raised, and after the rise, the heat-weldable elastic material string is repressurized and then cooled and heat-welded.
Thermal solvent bonding machine, characterized in that

While in the case of manual considered technically very difficult task, the advent of thermal solvent bonding machine bent surface of the heat-welding elastic material string, provides superior thermal welding to the uniformity and high-speed and safety Therefore, even if the worker changes, it becomes possible to provide a uniform and high-quality product, which is very useful for people who are currently manually working.

Pass the heat-weld elastic material string through the metal fittings by hand, place it on the upper surface of the machine mold, and press the push button switch to achieve accurate, uniform, high speed and safety.
