Hereinafter, the configuration and operation of a preferred embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show a plastic welder 100 using hot air according to an embodiment of the present invention. For convenience of description, in the present embodiment, the arrow direction in which the plastic welder 100 moves during the thermal fusion welding operation is defined as forward and the reverse direction is defined as the reverse direction. 1 and 2, a hot welding plastic welding machine 100 according to an embodiment of the present invention includes a body 110, a front wheel 120, A rear wheel 130, a power transmission unit 140, a hot air fan 150, a guide wheel 160, a handle 170, and a weight 180.

The main body 110 includes a case 111, a control panel installed to be exposed to the outside of the case 111, a driving motor and a blower installed inside the case 111, . The control panel includes a power switch 112, a plurality of selection buttons 113, a control dial switch 114, and a display 115. The moving speed, the temperature of the hot air, and the air volume of the hot air are adjusted by using the selection button 113 and the adjustment dial switch 114. [ The support base 119 is formed to extend laterally from one side of the front side of the case 111. And a fixing portion 119 to which the hot air 150 is fixed is installed on the support base 118. The fixing portion 119 is rotatable about a rotation axis (not shown) extending along the width direction and is coupled to the support 118 so as to be movable along the width. A power supply line 115 to which external power is supplied is connected to the main body 110. The plastic welder 100 is operated by the power supplied through the power line 115. A carrying handle 117 protruding upward is provided on the upper surface of the rear end portion of the main body 110. The operator grips the carrying handle 117 in a state other than the heat welding operation to carry the plastic welder 100. [ A weight 180 is detachably coupled to a rear end of the main body 110.

The front wheel part 120 is positioned at the front lower part of the main body part 110 to movably support the main body part 110. [ The front wheel portion 120 includes a first front wheel 121 and a second front wheel 122 which are disposed apart from each other along the width direction of the body portion 110 and freely roll. The first front wheel 121 is positioned generally below the main body 110 and the second front wheel 122 is positioned apart from the side where the support 119 of the main body 110 is located. The position of the first front wheel 121 can be adjusted to vary along the width direction. And is located at a first position below the main body 110. When the heat sealing function is performed, the operator moves a certain distance toward the second front wheel 122 and is positioned at the second position. That is, when the heat-sealing function is performed, the sheet is positioned on a relatively lower sheet among the two sheets to be fused.

The rear wheel portion 130 is located at the rear lower portion of the body portion 110 to movably support the body portion 110. The rear wheel portion 130 includes a first pressing wheel 131 and a second pressing wheel 132 arranged in a line along the longitudinal direction (moving direction) of the body portion 110.

The first pressing wheel 131 functions as a pressure roller in a heat welding operation and has a flat outer peripheral surface having a proper width. The first pressing roller 131 is placed on the overlapped portion of the two sheets to press the overlapped portion immediately after the heat fusion. The first pressing wheel 131 also functions as a driving wheel driven by receiving the rotational force by the power transmitting unit 140. The first presser wheel 131 causes the plastic welder 100 to move at an appropriate speed.

The second pressure wheel 132 is located behind the first pressure wheel 131 and functions as a pressure roller in the same manner as the first pressure wheel 131. The flat outer circumferential surface of the second pressure wheel 132 . The second pressing wheel 132 is preferably elastically supported so as to be movable up and down.

The power transmission unit 140 transmits the rotational force of the driving motor installed in the main body 110 to the first pressure roller 131. 3, the power transmitting portion 140 is shown. 3, the power transmitting portion 140 includes a driving pulley 141 rotated by a driving motor, and a belt 142 connecting the driving pulley 141 and the first pressing wheel 131 to each other.

The heat blower 150 includes a heating unit 151, a transfer unit 152, and a nozzle unit 153. The hot air fan 150 is detachably fixed to the fixing portion 119 to heat and discharge the air conveyed through a blower (not shown) provided inside the main body portion 110. The heating unit 151 heats the air conveyed through the conveyance pipe 155. The transfer unit 152 is extended from the heating unit 151 and the nozzle unit 153 is coupled to the end thereof. The hot air is transmitted to the nozzle unit 153 through the transfer unit 152. The nozzle unit 153 is detachably fixed to the end of the transfer unit 153. Hot air is blown through the nozzle unit 153. The nozzle portion 153 is a generally flat plate-like shape and is provided with a slot-shaped exhaust port 154 which is elongated in the width direction at the rear end. Hot air is blown through the exhaust port 154. Further, a plurality of discharge holes 155 are provided in the upper and lower plate portions of the nozzle portion 153, respectively. Hot air is also blown through the discharge hole 155. 5, the nozzle unit 153 having a flat shape is sandwiched between two overlapping sheets and is moved while jetting the hot air through the discharge port 154 and the discharge hole 155, S1 and S2 are thermally fused and pressed by the first and second pressing wheels 131 and 132 coming and going immediately after the nozzle unit 153 passes and the two sheets S1 and S2 are strongly fused.

The guide wheel 160 is coupled to the front of the main body 110 so that the width direction position and the vertical position can be adjusted. The side surface of the guide wheel 160 comes into contact with the side edge of the sheet S1 lying on top of the two sheets S1 and S2 during the thermal fusion welding operation. The movement direction of the plastic welder 100 is accurately guided by the guide wheel 160. [

The handle portion 170 has an extension rod portion 171 extending upward from the main body portion 110 and a handle 172 formed at an end of the extension rod portion 171. The tilted angle and length of the extension bar portion 171 can be suitably adjusted by appropriate means. The operator can move the plastic welder 100 by holding the handle 172 by hand.

The weight 180 is detachably coupled to the rear end of the main body 110. The weight 180 appropriately increases the pressing force by the two pressing wheels 131, 132. A plurality of weight weights 180 may be mounted as needed.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
