The cutting device and the swing device 50 can be controlled in time. And the belt pulling device 60 operates; that is, using the original composition constituted above, please cooperate with the fourth picture, when the PET plastic strap K is wound around the object E, we are The thumb of one hand can be positioned on the handle 80, and the other four fingers are held by the belt motor 608 of the belt pulling device 60 and pulled upwards, and the gearbox 602 and the belt of the belt pulling device 60 are pulled up. The wheels 603 and the gearbox side seat 604, etc., can be swung up and down on the base positioning arm 6011 by the screw 602 axe point, and cause the pull-wheels 603 ,, and directly to the rear side. The slider 60 5 has a non-meshing shape corresponding to a large distance. Next, the piston 30 is normally driven by the elastic element 20 to be raised upward to the top, and the rocking arm 5 of the swinging device 50 is caused. 1 cum up friction M258045, creation description (6) block 5 02 and cutting device 40 driving rod 40 3 cum cutter 401 tie belt is raised inwardly, then I can wind the strap K around the object The overlapping part K 'after e is directly placed on the side of the base 6 of the pulling device 60, and is located just below the pulling wheel 60 03, the upper friction block 50 2 and the cutting blade 401; then, please As shown in the fifth and sixth figures, when the overlapping portion of the strap κ is indeed located under the pull pulley 60 3, the upper friction wheel 502 and the cutter 401, we can Pulling motor 608 is lowered. The pulling wheel 603 can be pressed down to contact the strap κ, and the elastic element 7 on the side of the main body 10 is pressed to pull the pulling device 6 at any time. The upper end of the gearbox 602 of the 〇, when the pull-down motor 608 is lowered to cause the pull-down wheel 603 to be pressed down, it is inevitable that the overlapping straps can be surely elastically pressed and directly pulled by the ▼ wheel 603 and the stop slider 605 are engaged by pressure; then, when we press the first switch 9 0 of the air pressure control valve 90, the compressed air drives the belt pull motor 608 of the belt pull device 60 to rotate. The power train can be transmitted to the pulling pulley 603 through the worm 6023, the worm gear 6 022, and the shaft 6024. Naturally, the upper and lower belts of the strap overlapping portion κ that the pulling pulley 603 directly contacts and presses can be driven one by one. The displacement line tightens the action; then, when the strap K completes the tightening action on the object E, we can release the first switch 901 of the air pressure control valve 9 〇 and then press the second switch 9 〇 2. The compressed air enters the plenum 112 (see the sixth figure) of the outer cover 11 of the main body 10 and the driving swing device 50 at the same time.

Lost to the rocker arm 501, and caused the rocker arm 501 and the upper friction block 502 live on the lower end of the rocker arm 501 to be driven together to make a slight high-speed left and right swing cooperation. Naturally, the top friction block 502 The upper layer of the overlapping strap Γ can instantly generate high heat during high-speed swing friction, and directly connects with the overlapping lower strap to form an integrated body. As mentioned above, when the piston 30 is driven down and caused the welding device 50 to perform the welding operation on the overlapped band κ ′, the driving rod 40 of the cutting device 40 is also fixed to the piston 30, so that With the downward movement, and the cutter 401 penetrated by the driving rod 4 03 is supported by the elastic element 4 02 again, the upper layer of the strap overlapping portion K can be reached in an elastic manner during the downward movement. Belt, the cutting edge 40 1 3 of the cutting blade 40 1 is in the shape of a wrong tooth, and the upper layer of the overlapping band ^ ′ is oscillated by the upper friction block 5 2 of the swinging device 50, and the belt is at high speed. With the left and right swings, naturally, the cutter can quickly and surely cut the overlapping band Γ upper band by sawing the shape, and the operator of the packing of the bundle E is surely completed. Of course, because the overlapping portion κ of the strap is not driven by the friction block 5 0 2 above the swinging device 50, but stays tight and stationary, so when the swinging upper layer is elastically lowered, After the cutting blade 401 is sawn off, the cutting blade 401 will not produce any sawing action on the stationary lower belt at all, and it can ensure the authenticity of the strapping K. Next, when the strap K that is wrapped on the object E is welded and cut, we can release the second switch 902 of the air pressure control valve 90 and then press the second switch 90. 3. If the drive motor 5 of the swinging device 5 0 is not driven and causes the air in the air collection chamber 11 2 of the body cover 11 to be discharged, as shown in the third figure, the piston 30 can be elasticized. Element 2 0 springs back and returns

M258045

Both the friction block 502 and the cutting blade 401 of the cutting device 40 are moved upward and returned to facilitate the unpacking of the strap K. As mentioned above, please cooperate with the seventh figure. The base 601 of the strapping device 60 is located at the bottom of the side and is provided with an adjustment screw 6015, and the adjustment screw 6 0 1 5 is exposed to the top to carry the speed change. The bottom of the box 602 can be adjusted high and low. When the slacker pulls the belt motor 608 to cause the gearbox 602 and the belt wheel 603 to be pressed down together, the adjustment screw 6015 is exposed. The height adjustment can control the gearbox 602 and the draw down of the draw pulley 603, so that the draw pulley 603 can press the strap κ at the optimal height, and the operation system of the strap κ is sure and smooth. By. In other words ... the dynamic adjustment of the tightening screw 6 0 1 5 and the low adjustment operation, the pulling wheel 6 0 3 will be able to press the strap K at the optimal height, and the tightening action of the straps κ of various thicknesses Those who can achieve the desired smooth and effective results. As shown in the eighth and ninth figures above, as shown in the eighth and ninth figures, since the belt guide plate 607, which is provided on the front side positioning arm 60 of the strapping device 60, is driven by the elastic element 6072, Pulling force in the direction of the pulling pulley 603, so when the strap κ wound around the object E is placed in the side of the base of the pulling device 60 and is located below the pulling pulley 603, the elastic force is The belt guide plate 607 can be directly pushed and swung by the strap κ as the pivot point, without any hindrance to the driving operation of the strap κ by the pulling pulley 603. On the contrary, please cooperate with the 70th king tenth 2-picture shown when the pull motor 608 is pulled up and causes the pull pulley 603 even ▼ the upper hem does not engage the corresponding stop slider 60 5 and the bundle When the belt has not been placed under the puller pulley 60 3, the belt guide plate 607 is pushed by the force of the wheel 603 at any time, so it pushes the pull without being bound by the belt κ;

Page 12 M258045 IV. Creation instructions (9) In the case where the wheel 603 and the gearbox side seat 604 are swinging up again, it is inevitable that it will automatically spring and swing in the direction of the pull pulley 603 and just stop at At the outer cover 6041 of the transmission side seat 604, the tie-down pulley 603 which is coaxial with the transmission side seat 604 will not have a hem. In addition, the pulley 603 can be used for constant correspondence. The slider 605 does not engage with each other, and accidentally touches the first-position switch 901 of the air pressure control valve 而 and causes the pulling motor 608 to be driven. The pulling pulley—J stop slider 605 will not happen to each other at all. The damage phenomenon of direct friction is fin7qf. However, the lower end of the belt guide plate 607 is provided with a horizontal arc-shaped slot vertical wire. Therefore, it should be used in the interim. The user can also lock it through the screw 60 It can hold the positioner without swinging at the most appropriate position. In summary, the structure of this portable strapping machine is improved for the packing operation of heavy or large-sized objects that are generally inconvenient to carry, and it has the problem-solving performance that is extremely suitable for practical use.
