[0064] In order to make the technical content, purpose and effect achieved by the present invention more complete and clear, it is described in detail below. Please refer to the drawings and figure numbers in the specification:

[0065] First, see Figures 1 to 3 The figure shows the overall side view, three-dimensional appearance view, and plan side view of the taping pressure adjustment mechanism of the taping machine of the present invention. The taping machine A is mainly provided with a conveying mechanism C for carrying the packaging box B. Above the conveying mechanism C is a taping pressure adjustment mechanism D for performing taping operations on the corresponding packaging box. The taping pressure adjustment mechanism D includes:

[0066] A base 1 is provided with a tape reel 11 for placing a tape roll, and a plurality of guide rollers 12 for assisting in guiding the tape E. A sensor unit 13 for sensing the output length of the tape E is provided on one of the guide rollers 12. The sensor unit 13 is connected to a control switch 14. The control switch 14 can be a photoelectric switch, a micro switch, or a reed switch.

[0067] a taping arm pneumatic unit 2, mounted on the base 1 and having an output shaft 21, the taping arm pneumatic unit 2 being electrically connected to the control switch 14 (which may be a photoelectric switch);

[0068] A front taping arm 3, one end of which is pivotally mounted corresponding to the inlet end of the base 1, and the other end of which is provided with a contact pressure wheel 31 and a front guide wheel 12 for guiding the adhesive tape E. The adhesive tape passes through the front guide wheel 12 and is guided out of the contact pressure wheel 31. A first pivot assembly 32 is further provided on the front taping arm 3;

[0069] A cutter seat 4 is pivotally mounted on the base 1 and located below the front taping arm 3. One end of the cutter seat 4 is provided with a blade 41 and the other end is a return end 42. A protective cover 43 is pivotally mounted on the blade 41.

[0070] A rear taping arm 5, one end of which is pivotally mounted on the outlet end of the base 1, and the other end of which is provided with a flat pressing wheel 51, and the rear taping arm 5 is provided with a second pivot assembly 52, and a tension spring 53 is provided on the second pivot assembly 52, and one end of the tension spring 53 is connected to the output shaft 21 of the taping arm pneumatic unit 2;

[0071] a connecting rod 6, one end of which is corresponding to the first pivot portion 32 of the front tape arm 3, and the other end of which is corresponding to the second pivot portion 52 of the rear tape arm 5;

[0072] A smoothing brush 7 is provided at the rear of the rear tape arm 5 for smoothing the tape E cut by the blade 41 onto the packaging box B.

[0073] See also Figures 1 to 4 As shown, when actually implemented, the present invention is mainly used in thin packaging boxes B or packaging boxes B with little internal packaging, resulting in a void inside the box. Such packaging boxes B are weak (insufficient) in withstanding external pressure and are prone to sagging. Such packaging boxes B require the tape taping machine A of the present invention with adjustable taping pressure to complete the taping and sealing. The following is a detailed description:

[0074] When installing the tape roll, it is correspondingly placed on the tape wheel 11, and the tape E is pulled out to pass through each guide wheel 12, and a sensing unit 13 is provided on one of the guide wheels 12. The sensing unit 13 is used to sense the length of the tape E being pulled out, and then the tape E is wound around the front guide wheel 12 on the front taping arm 3 and guided out by the contact pressure wheel 31.

[0075] In addition, the position of the blade 41 on the cutter seat 4 is adjustable, and the normal length of the tape E can be cut to seal the two sides and the upper end surface of the packaging box B, or the longer length of the tape E can be cut accordingly and turned to seal it to the bottom end surface of the packaging box B. The tape E needs to be adhered to the bottom end surface in conjunction with a bottom folding brush group 8 installed on the conveying mechanism C. The bottom folding brush group 8 is located below the tape pressure adjustment mechanism D and includes a power unit 81. The power unit 81 is connected to a trigger 82 and is provided with a rack 811 at the output shaft end. The rack 811 is meshed with a gear 83 and is coaxially provided with a sprocket group 84. The sprocket group 84 is provided with a brush 85 (such as Figure 4 shown).

[0076] See also Figures 1 to 10 As shown, during actual use, the user can make choices and adjustments based on the type of packaging the box is to be packaged, such as activating the taping pressure adjustment mechanism D when sealing the two sides and upper end surface of the packaging box B, or activating the taping pressure adjustment mechanism D and the bottom corner brush group 8 at the same time when turning and sealing to the bottom end surface of the packaging box B; however, the following description describes the synchronous movement of the taping pressure adjustment mechanism D and the bottom corner brush group 8, which does not affect the movement of activating the taping pressure adjustment mechanism D alone.

[0077] First, before the packaging box B is introduced, the output shaft 21 of the taping arm pneumatic unit 2 is extended to an appropriate length to relax the tension spring 53 and maintain a small tension state; when the packaging box B is carried by the conveying mechanism C and introduced through the open end of the taping pressure adjustment mechanism D, the side of the packaging box B touches the contact wheel 31 of the front taping arm 3, and the tape E is adhered to the side of the packaging box B ( Figure 5 As shown), at the same time, the packaging box B pushes the touch wheel 31 upward, and also pushes the cutter seat 4, so that the cover 43 is opened and the blade 41 is rotated upward ( Figures 6 and 7 As shown in the figure, when the front taping arm 3 rotates, it drives the connecting rod 6, and the connecting rod 6 drives the rear taping arm 5 to rotate, so that the flat pressure wheel 51 rotates upward to correspond to the upper end surface of the packaging box B. Because the rear taping arm 5 is restrained by the connecting rod 6 and the tension spring 53, the contact pressure wheel 31 of the front taping arm 3 and the flat pressure wheel 51 of the rear taping arm 5 will not exert excessive pressure on the packaging box B. In this way, the packaging box B can be kept intact and not collapsed.

[0078] Next, the packaging box B continues to move forward and the tape E is pasted. The length of the tape E is calculated by the sensing unit 13 on the guide wheel 12, and then the output shaft 21 of the taping arm pneumatic unit 2 is driven to retract by the control switch 14, so as to increase the tension of the tension spring 53 acting on the rear taping arm 5. At this time, the tape E has been cut and is pasted to the side of the packaging box B (as shown in FIG. Figure 8 Then, the flat pressure wheel 51 of the rear tape arm 5 follows the side of the packaging box B and hangs down and caresses the tape E (as Figure 9 Figure 10 shown).

[0079] After the packaging box B is taped, the packaging box B passes over the smoothing brush 7 behind the rear taping arm 5. The smoothing brush 7 smoothes the tape E cut by the blade 41 onto the packaging box B. Simultaneously, when the packaging box B is removed from the cutter block 4, a return spring 44 is provided at the return end 42 of the cutter block 4. One end of the return spring 44 is positioned on the base 1. After the packaging box B is removed, the return spring 44 drives the cutter block 4 to return to its original position, allowing the protective cover 43 to cover the blade 41.

[0080] See also Figures 1 to 10 As shown, if the tape E needs to be stuck to the bottom, when the packaging box B enters the bottom corner brush group 8, it will first contact the trigger 82, causing the trigger 82 to start the rack 811 at the output shaft end of the power unit 81 to extend out, thereby driving the gear 83 and linking the sprocket group 84, so that the brush 85 on the sprocket group 84 can brush from front to back, and brush the tape E stuck on the front side of the packaging box B flat toward the bottom end surface; when the packaging box B passes through and separates from the trigger 82, the rack 811 at the output shaft end of the power unit 81 is started and retracted, thereby driving the gear 83 and linking the sprocket group 84, so that the brush 85 on the sprocket group 84 can brush from back to front, and brush the tape E stuck on the back side of the packaging box B flat toward the bottom end surface.

[0081] The aforementioned embodiments or drawings do not limit the structural form of the present invention. Any appropriate changes or modifications by ordinary technicians in the relevant technical field should be deemed to be within the scope of protection of the present invention.

[0082] In summary, the embodiments of the present utility model can indeed achieve the expected use effect. Moreover, the specific structure disclosed therein has not been seen in similar products and has not been disclosed before the application. Therefore, it fully complies with the provisions and requirements of the Patent Law.
