The matching puller motor 608 and the gearbox 602 can be matched with each other. Pulling pulley 603, gearbox side seat 604, etc. up and down swing operation; a pneumatic control valve 90 , according to the rear end of the body 10, can be controlled by a plurality of switches 901, 902, 903, and through the airway A of the body 10 (see the third figure), the air inlet 5042 of the drive motor 504 (see the second figure) The drawing of the air tube B of the motor 608 is carried out, and the compressed air is respectively delivered to the plenum 112 of the outer cover 10 and the driving motor 504 of the swinging device 502 and the drawing motor 608 of the pulling device 60., the cutting device 40, the swinging device 50 and the drawing device 60 can be controlled in time; that is, with the above-mentioned creation, please cooperate with the fourth figure, when the PET plastic strap K is wrapped around the bundle. After E, the person can position the thumb of one hand on the handle 80, and the remaining four fingers are gripped by the draw motor 608 of the draw unit 60 and push it up, the gearbox 602 of the draw unit 60, The pull pulley 603, the transmission side seat 604, and the like can be pivoted up on the base positioning arm 6011 with the screw 6021 as a pivot point, and the pull pulley 603 is tilted directly to the stop slider 605. The non-meshing shape corresponding to the large pitch; in turn, the piston 30 is normally actuated by the elastic member 20 When it is lifted up to the apex, and the rocker arm 501 of the swinging device 50 and the upper friction block 502 and the driving rod 403 of the cutting device 40 and the cutter 401 are pulled up, we can The overlapping portion K after the bundle K is wound with the bundle E is directly placed on the side of the base 601 of the drawing device 60, and is located just below the pulley 603, the upper friction block 502 and the cutter 401; Referring to the fifth and sixth figures, when the overlapping portion K of the strap K is indeed located below the pull pulley 603, the upper friction wheel 502 and the cutter 401, the pull motor 608 can be lowered and pulled. The pulley 603 can be coupled with the lower belt and the strap K, and the elastic member 70 disposed on one side of the body 10 elastically presses the upper end of the gearbox 602 of the strap device 60, and the strap motor 608 is pulled down. When the pulley 603 is pressed down, it is inevitable that the overlapping strap K can be elastically pressed and directly pressed by the pull pulley 603 and the stop slider 605; then, when we press the air pressure control The first switch 901 of the valve 90, when the draw motor 608 of the compressed air drive puller device 60 rotates, the power train can pass through the worm 60 23, the worm wheel 6022, the shaft 6024 is transmitted to the pull pulley 603, naturally, the belt pulley 603 is in direct contact with and pressed by the strap overlapping portion K, the upper belt can be driven one by one to drive the tensioning action; ,

In the above, when the piston 30 is driven down and the swinging device 50 is engaged with the overlapping strap K, the driving rod 403 of the cutting device 40 is also fixed to the piston 30 and can be moved downward. And the cutter 401 which is driven by the driving rod 403 is further supported by the elastic member 402, and can be elastically touched with the overlapping portion K, and the upper belt at the cutting edge of the cutter 401. The 4013 is in a zigzag shape, and the overlapping strap K is in turn oscillated by the upper friction block 502 of the swinging device 50, and the belt is rotated at a high speed left and right. Naturally, the cutter can be sawed. The cutting form quickly and surely binds the overlapping strap K, and the upper layer is cut, and the bundle is actually completed by the bundled carrier E. Of course, since the lower belt of the strap overlapping portion K is not driven by the friction block 502 on the swinging device 50, but is kept stationary, the upper layer of the swing is elastically pressed. After the knife 401 is sawn off, the cutter 401 will not cause any sawing action on the stationary lower belt, and the authenticity of the strap K binding can be ensured.

Then, after the binding and the cutting operation of the bundle K of the bundle E, the second switch 902 of the air pressure control valve 90 can be released and the third switch 903 can be pressed continuously. The drive motor 504 of the device 50 is not driven and the air in the plenum 112 of the outer cover 11 is discharged. As shown in the third figure, the piston 30 can be spring-returned by the elastic member 20 and the friction block is applied thereto. 502. The cutters 401 of the cutting device 40 are all moved up and back to facilitate the separation of the straps K of the bundle.

In the above, as shown in the seventh figure, the bottom of the base 601 of the drawing device 60 is provided with an adjusting screw 6015, and the adjusting screw 6015 is attached to the bottom of the gearbox 602 in an exposed manner. When the high and low adjustments are implemented, when the transmission belt 602 and the pulley 603 are pulled down together, the height adjustment of the adjustment screw 6015 can be used to control the transmission 602 and the pulley 603. The magnitude of the pressing force, in turn, allows the pull-up pulley 603 to strike the strap K at an optimum height, and the operating strap of the strap-up belt K being driven to be tightened is more effective and smooth. In other words, with the height adjustment of the adjusting screw 6015, the pulling pulley 603 can press the strap K with the best height, and the tensioning action of the strap K of various thicknesses can achieve the smoothness and the actual need. Effect.

In the above, as shown in the eighth and ninth figures, since the tape guide plate 607 provided on the front end surface of the base positioning arm 6011 of the tape drawing device 60 is actuated by the elastic member 6072, it has the direction of the pull pulley 603 at any time. The force of the elastic force, so when the strap K wound around the bundle E is placed on the side of the base of the draw belt device 60 and under the pull pulley 603, the elastic force guide strip 607 can be used to position the screw 6071 is that the pivot point is directly swung by the strap K, and the driving operation of the strap K by the pull pulley 603 is completely obstructed. On the contrary, please cooperate with the tenth and eleventh figures, when the draw motor 608 is pulled up and the pull pulley 603 is attached to the upper swing without engaging the corresponding stop slider 605, and the strap K is not yet placed. When the pull-in pulley 603 is inserted underneath, since the tape guide plate 607 has a force to be biased toward the pull-up pulley 603 at any time, it is pushed in the unbelted K and the pull-up pulley 603 and the transmission side seat. In the case where the 604 is again in the upper swing, it is inevitable that it will automatically swing in the direction of the pull pulley 603 and just stop at the outer cover 6041 of the transmission side seat 604, and be coaxial with the transmission side seat 604. The pull pulley 603 is not attached to the hem, and the pull pulley 603 can be misengaged with the corresponding stop slider 605, and the first switch 901 of the pneumatic control valve 90 is accidentally touched. When the pull-up belt motor 608 is driven, the pull-up pulley 603 and the stop slider 605 will not be damaged at all by direct friction.

Of course, since the lower end of the tape guide plate 607 is provided with a lateral arcuate groove 6073, the user can also lock it by the screw 6074 according to the needs of actual use, and the position can be maintained at the most appropriate position without swinging. By.

In summary, the present invention provides a structural improvement of a portable strapping machine. For the packing operation of heavy or large-sized objects that are generally inconvenient to handle, it is apparent that the problem-solving performance is extremely satisfactory for practical use, and the device and structure thereof are provided. Although it does not appear complicated and cumbersome, the overall operational concept is rich in the specificity of implementation, and it is not used in the current products of the same type. Therefore, Chengcheng has met the new patent application with "newness, progress and industry availability." The requirements of the "sex", I would like to ask the reviewing committee to review and grant patents, without any prayer.
