[0002]

[Prior art]

 In order to effectively pack the boxes to be transported, a band of a certain width is usually wrapped around the boxes to enhance connectivity. Older packing machines or banding machines were hand-operated, connecting the bands with metal fasteners. Since this mechanism is manually operated, it is rather inconvenient, and the metal fasteners for fixing do not have strong bonding, and the band may fall off or the metal fasteners may damage the human body. Was not practical.

At present, there is an electric banding machine, which drives a tightening mechanism and a hot-melt mechanism by a motor, and advances the packing of articles electrically. However, such an electric banding machine must provide a non-planar tightening passage or a double band passage in order to prevent the band from moving backward during the hot melt stage. Therefore, the tightening operation cannot be performed well, and the friction wheel is directly driven, so that the reduction ratio cannot be increased.In a high-speed rotational friction situation, the life of the friction wheel is shortened and is not practical. Was. Its overall structure had a fixed connection form, could not be used in a modular fashion, its manufacturing process was complicated, it could not be applied alternately, and its practicality was limited.

A positioning block 18 having a positioning spring steel ball 181 is separately provided between the lower friction pieces, and is used to apply to the binding bands 9 having different widths.

After the binding band 9 is wound at the proper position by wrapping it around the article, the pulling rod 12 and the lock piece 8 are opened. Are restored to their original positions, and the two rubbing wheels 48 below the fixing plate 45 horizontally and evenly press tightly on the binding band 9, which When the cross shaft 47 of the transmission source is pressed by the rotation of the interlocking shaft 431, the friction wheel 48 having the cross groove 482 assumes a balanced state with the cross shaft 47. When the switch 13 is actuated by pressing the upper end of the extension piece 16 forward, the motor 2 drives the main shaft 21 to rotate forward, and the interlocking of the worm 211 and the worm wheel 23 and the one-way bearing 41 Upon receiving the transmission, the transmission shaft 42 rotates (when the main shaft rotates in reverse, the transmission shaft 42 does not interlock), the transmission shaft 42 further transmits to the gears 46, 461, 462, and the cross shaft 47 of the gears 461, 462 is moved.

At the same time, the inverted U-shaped frame 56 is tilted to activate the contact switch 73, so that the motor 2 is stopped first, the tightening mechanism 4 is stopped, the motor 2 is further reversed in the reverse direction, and the unidirectional bearing 22 is As shown in FIG. 13, the fixed seat 53 and the welding seat 54 perform a rapid reciprocating reciprocating movement in a lateral direction, as shown in FIG. The piece 542 receives the action force of the upper spring 551, and the lower tooth surface presses the upper banding band 91 to form friction at a high speed with the lower banding band 92 to melt it, thereby forming the upper layer. The binding band 91 of the lower layer and the binding band 92 of the lower layer are combined. The adjustment wheel 55 is provided to rotate to adjust the pressure on the upper friction piece 542 of the spring 551, thereby adapting to the demands of different situations.

Also, the oblique cone surface 33 of the horizontal bar 3 pushes the convex portion 561 of the inverted U-shaped frame 56 to restore the inverted U-shaped frame 56 to the original vertical position, and the inverted hook portion 562 at the lower end of the inverted U-shaped frame 56. During rotation, the welding seat 54 is lifted and the binding band is released by the design of the oblique guide surface. In addition, the guide post 34 at the end of the horizontal bar 3 pushes the lower oblique guide surface 632 of the tension bar 63 to move the tension bar 63 downward, and the active block 7 is restored to the original position. Further, as shown in FIG. 9, in the present invention, the active block 7 is advanced to the lower end piece by using the extended piece 16 on the side of the handle 11 and manually pressing the side end of the extended piece 16. In this way, when the user recognizes that the binding strength is insufficient, the tightening is stopped in advance to start the welding cutting operation, or when the user does not want the automatic tension control, the welding cutting action is manually performed. You have control.

In the present invention, one adjusting knob 17 of an eccentric design is provided outside the corner of the inner fixing plate 43 in the main body (FIG. 5), and the distance between the inner fixing plate 43 and the lower friction piece 15 is reduced. When the corner of the inner fixing plate 43 comes into contact with a relatively small radius portion of the adjustment knob 17, the above-described distance becomes relatively small, and the adjustment knob 17 is rotated. When the relatively large radius portion is brought into contact with the inner fixing plate 43, the above-mentioned distance is made relatively large, so that a tie band having a different thickness can be used, and when there is no tie band, It is designed to maintain a safe distance.

In summary, the present invention utilizes a single motor, combines two sets of unidirectional bearings, and effectively drives the tightening mechanism and the welding cutting mechanism when the motor rotates forward and backward, respectively, to effectively operate the motor. It is possible to progress the binding operation of the articles, and it has practicality. And, after the binding band is mounted, the design of the unidirectional bearing 41 allows the user to manually correct the position of the binding band first and tighten it appropriately, thereby reducing the time of the tension tightening operation. It can be reduced, the function is enhanced, and the tightening mechanism has a structure combining the worm, worm wheel and gears in the inner fixed plate, so it is used at a high reduction ratio and tightens the binding band. Since the friction wheel of the present invention and the transmitting gear are loosely combined by a cross shaft and a cross groove to transmit power, the flatness of the two friction wheels can be reduced. It is controlled so that uniform force and tightening can be applied to the binding band. Therefore, the tightening operation can be performed on the same plane, which is convenient for implementation, and when the tightening operation proceeds, the tightening operation is performed. Cook piece By utilizing the locking of the pull bar 12 with the locking column 122 by the locking edge 81 of FIG. 8, the binding band is effectively pressed tightly against the fixing plate 45, and loosened and dropped due to the recovery force generated at the time of tightening. Does not occur.

As shown in FIG. 14, a backing plate 454 is connected to the inside of the lower side of the fixed plate 45 by a screw 453, and the position of the backing plate 454 is adjusted by the screw 453, so that bindings of different widths are formed. Bands are made available so that the slats 454 provide a guiding action when the articles are bound. An exchangeable positioning block 18 can be installed between the friction pieces 15 in the bottom seat 14, and a spring steel ball 181 above the positioning block 18 is combined with the adjustment of the abutment plate 454 to form a binding band. The positioning and direction guiding effects are enhanced. Each friction piece and cutter can be of a replaceable design, which can be easily replaced when its friction surface wears out, and uses the body continuously. In addition, as shown in FIG. 10, the tension setting device 6 is provided with another adjusting wheel 64, and by rotating the adjusting wheel 64, the strength of the spring 65 thereunder can be adjusted. The tension of the binding band 9 which is received by the user can be adjusted, that is, the binding strength to the article can be set, and as shown in FIGS. Combined with the column 671 on the lower block body 67, the strength can be indicated, and it is convenient for tension adjustment and setting, and has a stepping property. In addition, the tightening mechanism of the present invention has a modular design, so that different reduction ratios can be achieved with different gear structures or gear ratios. For example, the gear transmission of the fixed plate of the present invention shown in FIG. According to a modified embodiment, the gears arranged linearly in a row are meshed with each other. Therefore, any simple modifications or alterations made in the spirit of the present invention shall fall within the scope of the claims of the present invention.
