[0053] The details of the present invention can be more clearly understood by referring to the accompanying drawings and the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are for the purpose of explaining the present invention only and should not be construed as limiting the present invention in any way. Based on the teachings of the present invention, skilled artisans can conceive of any possible variations based on the present invention, which should be considered to fall within the scope of the present invention.

[0054] 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:

[0055] First, see Figures 1 to 4 The figure shows the three-dimensional appearance, side view and installation diagram of the pneumatic single-stage or multi-stage taping 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 mechanism D for performing side sealing and taping operations on the corresponding packaging boxes. The taping mechanism D includes:

[0056] A base 1 is provided with a tape wheel 11 for placing a tape roll, and a guide wheel assembly 12 for assisting in guiding the tape E, and a movable groove 13 is provided on the base 1;

[0057] a taping arm pneumatic unit 2, mounted on the base 1 and having an output shaft 21;

[0058] A taping arm 3 is pivotally mounted on the base 1 , with a pressure wheel 31 provided at the front end of the taping arm 3 and a rear end connected to the output shaft 21 of the taping arm pneumatic unit 2 ;

[0059] A tape adjustment wheel assembly 4, comprising a base 41, and correspondingly pivoted at the pivotal location between the taping arm 3 and the base 1. An intermediate wheel 42 for the tape to pass through is provided at one end of the base 41, and a pressure adjustment wheel 43 is provided at the other end, with the tape E being clamped between the pressure adjustment wheel 43 and the contact pressure wheel 31;

[0060] A cutter seat 5 is pivotally mounted on the base 1 and is located on one side of the tape arm 3. One end of the cutter seat 5 is embedded in a movable groove 13 provided on the base 1, and the other end is provided with a cutter 51 for cutting the tape E. A tension spring 52 is hooked on the cutter seat 5, and one end of the tension spring 52 is hooked on the base 1;

[0061] a guide plate 6, assembled and fixed on the base 1 and located behind the cutter 51 of the cutter seat 5, the guide plate 6 having a vertical guide surface 61 for pressing the outer side of the tape E downward for adhesion;

[0062] A first control switch 7 and a second control switch 8 are respectively arranged on the path of the conveying mechanism C for transporting the packaging box B. The taping mechanism D is started by touching the first control switch 7 on the packaging box B, and the second control switch 8 is touched to drive the taping arm pneumatic unit 2 to move, so that the contact pressure wheel 31 of the taping arm adheres the tape E to the packaging box B. After the packaging box B is separated from the first control switch 7, the taping arm pneumatic unit 2 is driven to move, so that the cutter 51 of the cutter seat 5 cuts the tape E.

[0063] When installing the tape roll, it is correspondingly placed on the tape wheel 11, and the tape E is pulled out to pass through the guide wheel group 12. The guide wheel group 12 is used to guide the tape E into the tape adjustment wheel group 4, allowing the tape E to pass through the intermediate wheel 42 and be clamped between the pressure adjustment wheel 43 and the contact pressure wheel 31.

[0064] See also Figures 5 to 16As shown, in actual operation, the present invention mainly uses a packaging box B with a single lid and side seal, and the side gluing can also be performed in a single-stage gluing or multi-stage gluing manner. The air pressure control of the gluing is mainly achieved through the first control switch 7, the second control switch 8 and the time control, which is described in detail below:

[0065] Example 1 is a single-section adhesive tape, please refer to Figures 5 to 11 As shown, before being started, the output shaft 21 of the taping arm pneumatic unit 2 extends to an appropriate length to drive the taping arm 3 to rotate an angle, so that the pressure wheel 31 at the front end of the taping arm 3 retracts upward; when the packaging box B is carried by the conveying mechanism C and introduced into the open end of the taping mechanism D, the side of the packaging box B touches the first control switch 7 on the conveying path to start the taping mechanism D. When the packaging box B touches the second control switch 8, the output shaft 21 of the taping arm pneumatic unit 2 is retracted, the taping arm 3 is rotated, and the pressure wheel 31 at the front end is lowered, so that the upper end surface of the side of the packaging box B touches the pressure wheel 31, and the inner side of the tape E (half area) is adhered to the upper end surface of the side of the packaging box B ( Figures 5 to 7 However, because the package B is a single-lid side-sealed type, the tape E will not be applied starting at the corners of the three end faces. Instead, the package B is allowed to move forward a slight distance until it touches the second control switch 8, and then the tape E is applied starting from an appropriate distance in front of the upper end of the side. Relatively speaking, the back section will also end early, leaving a section unapplied.

[0066] Then, the packaging box B is continuously transported to the exit end, and the adhesive tape E is continuously adhered, while the outer side (the other half area) of the adhesive tape E passes through the vertical guide surface 61 of the guide plate 6, and its outer side is bent downward and guided to adhere to the side end surface of the packaging box B. Furthermore, a rotary brush 62 is provided behind the guide plate 6, and the adhesive tape E bent and guided by the vertical guide surface 61 is smoothed and brushed to adhere to the side end surface of the packaging box B by the rotary brush 62; when the packaging box B leaves the first control switch After closing 7, the pneumatic unit 2 of the taping arm is started to extend the output shaft 21, so that it drives the contact pressure wheel 31 on the taping arm 3 to approach the cutter 51 of the cutter seat 5, and the cutter seat 5 moves along the side arc segment 32 of the taping arm 3 toward the vertical segment 33, so that the cutter 51 is displaced toward the tape E, and the cutter 51 of the cutter seat 5 cuts the tape E between the packaging box B and the contact pressure wheel 31; in this way, the tape E can be cut, completing the side-sealed single-stage pasting operation (such as Figure 11 shown).

[0067] After the tape E is cut, the packaging box B continues to be conveyed backward. At this time, at least one flattening roller 14 is installed on the taping machine behind the taping mechanism. This roller 14 smoothes the outer edge of the cut tape E against the side surface of the packaging box B, ensuring a more secure adhesion. Finally, after the taping is completed, the output shaft 21 of the taping arm pneumatic unit 2 is pushed out, driving the taping arm 3 to return the contact pressure roller 31 to its original position. The cutter seat 5, through the elastic force of the tension spring 52, returns the cutter 51 to its original position.

[0068] Example 2 is a multi-section adhesive tape (this example uses front and back sections for adhesive tape). Figures 5 and 6 、 Figures 12 to 16 As shown, its general action process is the same as the aforementioned single-stage pasting, and the difference lies in the time control. In the process of multi-stage pasting tape, the first time controller 9 and the second time controller 10 are further used to assist the multi-stage pasting and cutting of the tape E. The first time controller 9 and the second time controller 10 are respectively connected to the taping arm pneumatic unit 2, so as to control the taping arm pneumatic unit 2 to drive the taping arm 3 to tap and the cutter seat 5 to cut the tape through time calculation (such as Figure 12 As shown); the following examples illustrate the pasting method of the front and back sections: before starting, the output shaft 21 of the taping arm pneumatic unit 2 extends an appropriate length to drive the taping arm 3 to rotate an angle, so that the pressure wheel 31 at the front end of the taping arm 3 retracts upward. When the packaging box B is introduced, its side touches the first control switch 7 on the conveying path to start the taping mechanism D. When the packaging box B touches the second control switch 8, the output shaft 21 of the taping arm pneumatic unit 2 retracts, and the pressure wheel 31 at the front end of the taping arm 3 descends, so that the inner side of the tape E is adhered to the upper end surface of the side of the packaging box B ( Figures 5 and 6 However, after touching the second control switch 8, the first time controller 9 starts timing the front-end pasting time (for example, 0.5 to 1 second, that is, the length of the pasting tape). When the front-end pasting time ends, the taping arm pneumatic unit 2 is driven to extend the output shaft again, so that it drives the touch-pressure wheel 31 on the taping arm 3 to approach the cutter 51 of the cutter seat 5, and allows the cutter seat 5 to move along the side arc segment 32 of the taping arm 3 toward the vertical segment 33, so that the cutter 51 is displaced toward the tape E, and the cutter 51 of the cutter seat 5 is allowed to cut the front-end tape E of the tape E between the packaging box B and the touch-pressure wheel 31.

[0069] After the cutting of the front section of tape E is completed, the taping arm 3 and the cutter seat 5 are reset, and the cutter 51 is retracted. Then, the second time controller 10 is used to time again (for example, 2 to 2.5 seconds). This is to calculate the interval time, which is the distance time between the front section of tape and the rear section of tape. When the time is up, the time for the rear section to be pasted is started (for example, 1.5 to 2 seconds). At this time, the taping arm pneumatic unit 2 drives the touch pressure wheel 31 of the taping arm 3 to descend, and the inner side of the tape E is adhered to the rear section of the upper end surface of the side of the packaging box B to start pasting the rear section of the tape E. When the packaging box B is separated from the first control switch 7, the taping arm pneumatic unit 2 will be started again to extend the output shaft 21 again to cut the rear section of the tape E. As mentioned above, the cutting action is performed after the pasting time is calculated by the first time controller 9, and no further details will be given. In this way, the pneumatic and air pressure control of multiple sections of pasting can be completed (such as Figure 15 shown).

[0070] 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.

[0071] In summary, the embodiments of the present utility model can indeed achieve the expected use effect. The specific structure disclosed therein has not been seen in similar products and has not been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law.
