[0036] Example 1:

[0037] Please refer to Figure 1-4 This embodiment discloses an electric sealing tape device, including a box head sealing mechanism and a box tail sealing mechanism 80; a sealing station 90 is formed between the box head sealing mechanism and the box tail sealing mechanism 80, and the sealing station 90 is formed on the carton conveying channel of the carton sealing machine, allowing cartons to pass through. In this embodiment, the carton conveying channel of the carton sealing machine is a bottom-up lifting channel, that is, the carton inlet of the sealing station 90 is at the bottom, and its carton outlet is at the top, so that the carton completes the sealing process during the upward lifting process, which is beneficial to the spatial layout of the carton sealing equipment. The box head sealing mechanism is used to seal the box head with tape, and the box tail sealing mechanism is used to seal the box tail with tape. The box head sealing mechanism and the box tail sealing mechanism 80 are arranged opposite each other on both sides of the sealing station 90.

[0038] The box-head sealing mechanism includes a tape supply assembly 10 and a sealing assembly 20. The tape supply assembly 10 includes a tape roller mounting plate 11, a tape supply roller 12, a tape conveying drive roller 13, and a tape conveying drive component 14. The tape roller mounting plate 11 mainly serves as a support and connection, used to fix the box-head sealing mechanism to the main frame of the box-sealing machine. The end of the tape supply roller 12 is rotatably connected to one side of the tape roller mounting plate 11; the end of the tape conveying drive roller 13 is rotatably connected to the tape roller mounting plate 11, and the tape conveying drive component 14 is drively connected to the tape conveying drive roller 13. The tape conveying drive component 14 is a geared motor, and the tape conveying drive component 14 is fixed to the other side of the tape roller mounting plate 11, with its output shaft connected to the tape conveying drive roller 13.

[0039] In use, the sealing tape 121 is wrapped around the glue supply roller 12, and the sealing tape is wound around the glue delivery roller 13 and extends to the sealing assembly 20. The sealing assembly 20 then seals the carton head with the tape, achieving automatic sealing. In this embodiment, the glue delivery drive 14 drives the glue delivery roller 13 to rotate, providing power to the sealing tape in contact with it. This powers the sealing tape to the sealing assembly 20, which then attaches the sealing tape to the carton's leaf joint. Compared to the traditional method where the carton's movement pulls the sealing tape to generate power, this embodiment actively provides power to the sealing tape by transmitting the power of the glue delivery drive 14 through the glue delivery roller 13. This ensures a smooth release of the tape, avoids uneven tension leading to poor adhesion or breakage, and significantly improves sealing efficiency.

[0040] Furthermore, the tape supply assembly 10 also includes a first guide roller 131 and a second guide roller 132, both of which are rotatably connected to the tape roller mounting plate 11. The first guide roller 131 and the second guide roller 132 are respectively disposed on opposite sides of the active tape conveying roller 13, and guide the sealing tape through the first guide roller 131 and the second guide roller 132, thereby increasing the contact area between the sealing tape and the surface of the active tape conveying roller 13.

[0041] The surface of the active roller 13 for conveying glue has a knurled surface 133, which is used to contact the sealing tape. The knurled surface 133 can increase the friction between the active roller 13 for conveying glue and the sealing tape.

[0042] By increasing the contact area and friction between the sealing tape and the surface of the conveying roller 13, the power transmission efficiency of the conveying roller 13 for the sealing tape is improved.

[0043] The tape supply assembly 10 in this embodiment further includes a tension roller 15, a tensioning elastic element 16, and a tensioning connecting plate 17. The tensioning connecting plate 17 is hinged to the tape roller mounting plate 11. One end of the tensioning connecting plate 17 is connected to the tape roller mounting plate 11 through the tensioning elastic element 16, and the other end is rotatably connected to the tension roller 15. A first winding roller 151 and a second winding roller 152 are provided on both sides of the tension roller 15. The sealing tape is sequentially wound around the first winding roller 151, the tension roller 15, and the second winding roller 152 in the circumferential direction. The tensioning elastic element 16 provides an elastic force that drives the tension roller 15 away from the axis connecting the first winding roller 151 and the second winding roller 152, thereby adjusting the tension of the sealing tape during the conveying process and further ensuring the smooth release of the tape.

[0044] The tape roller mounting plate 11 is provided with a tension sensor 18 and a balance sensor 19; the tension sensor 18 is a proximity switch located near the tension roller 15, which obtains the position information of the tension roller 15; the balance sensor 19 is a diffuse reflection sensor located near the glue supply roller 12, which is used to obtain the balance information of the sealing film roll 121.

[0045] It also includes a tension control module and a low-load indicator module, both integrated into the main control system of the carton sealing machine. The tension control module is signal-connected to the tension sensor 18 and electrically connected to the adhesive conveying drive 14. The tension control module controls the rotation speed of the adhesive conveying drive 14 based on the feedback signal from the tension sensor 18. The position of the tension roller 15 is sensed by a proximity switch to determine the tension of the sealing tape, thereby accelerating or decelerating the rotation of the adhesive conveying drive 14 to achieve flexible tape supply. The low-load indicator module is signal-connected to the low-load sensor 19 and outputs a film roll replacement alarm based on the feedback signal from the low-load sensor 19. When the film roll load is too low, the system triggers an alarm to prompt tape replacement.

[0046] The sealing assembly 20 in this embodiment includes a sealing substrate 21, a sealing mechanism frame 22, a sealing core support rod 23, a pressing core support rod 24, a sealing mechanism and a pressing mechanism, and a sealing component 25.

[0047] The sealing substrate 21 mainly serves as a support and connector. The sealing mechanism frame 22 is fixed to one side of the sealing substrate 21. The sealing core support rod 23 and the pressing core support rod 24 are rotatably connected to the sealing mechanism frame 22 along the carton conveying direction. The sealing mechanism and the pressing mechanism are rotatably connected to the ends of the sealing core support rod 23 and the pressing core support rod 24 near the sealing station 90, respectively. The other ends of the sealing core support rod 23 and the pressing core support rod 24 are hinged by a linkage rod. Both the sealing core support rod 23 and the pressing core support rod 24 can rotate on the sealing machine frame 22, driving the sealing core and pressing core at the ends to extend or retract at the sealing station 90; an elastic element is provided between the sealing core support rod 23 and the sealing machine frame 22, the elastic element providing elastic force to drive the sealing core into the sealing station 90; the cutting element 25 is elastically connected to the sealing machine frame 22 through a knife holder seat, and the cutting element 25 is driven by the knife holder seat to extend and cut the sealing tape.

[0048] The sealing assembly 20 also includes box side guide plates 26. The two box side guide plates 26 are respectively disposed on both sides of the sealing machine core frame 22. The box side guide plates 26 guide the carton and guide the carton to make circumferential contact with the sealing machine core and the pressing machine core.

[0049] The box sealing mechanism of this embodiment also includes an adjustment component 30, which includes an adjustment frame 31 and an adjustment base plate 32. The adjustment frame 31 is used to connect with the main frame of the box sealing machine, and the adjustment base plate 32 is slidably connected to the top of the adjustment frame 31. The adjustment base plate 32 is used to connect with the sealing component 20.

[0050] A width adjustment handwheel 321 and a width adjustment screw are provided at the connection between the adjustment base plate 32 and the adjustment frame 31. The width adjustment screw is connected to the adjustment frame 31 through a screw support seat. One end of the width adjustment screw is screwed to the adjustment base plate 32 through a ball nut, and the other end is connected to the width adjustment handwheel 321. The width adjustment handwheel 321 drives the adjustment base plate 32 to slide on the adjustment frame 31, so that the adjustment base plate 32 moves closer to or away from the sealing station 90, thereby adjusting the sealing width position.

[0051] A locking element is provided at the connection between the width adjusting screw and the adjusting frame 31. The locking element locks the relative position of the width adjusting screw and the adjusting frame 31 by means of a shaft clamping mechanism.

[0052] The sealing substrate 21 is connected to the adjusting substrate 32 via several guide rods; a height adjustment handwheel 211 and a height adjustment screw are provided between the sealing substrate 21 and the adjusting substrate 32.

[0053] The box sealing mechanism also includes a box pressing assembly 40, which is located near the carton entry end of the packing station. The box pressing assembly 40 limits the carton pages and keeps the carton pages in a folded state.

[0054] The pressure chamber assembly 40 includes a pressure chamber base plate 41, a pressure chamber adjusting screw, and a pressure chamber adjusting handwheel 411. The pressure chamber base plate 41 is connected to the chamber head adjusting base plate 32 via several guide rods. The pressure chamber adjusting screw is screwed to the adjusting base plate 32 via a screw nut. The top end of the pressure chamber adjusting screw is connected to the pressure chamber base plate 41 via a screw support seat, and the bottom end of the pressure chamber adjusting screw is connected to the pressure chamber adjusting handwheel 411. The pressure chamber base plate 41 is driven to move closer to or further away from the adjusting base plate 32 by the pressure chamber adjusting handwheel 411, thereby adjusting the height position of the pressure chamber.

[0055] A locking element is provided at the connection between the pressure box adjusting screw and the pressure box head adjusting base plate 32. The locking element locks the relative position of the pressure box adjusting screw and the adjusting base plate 32 by means of a shaft clamping mechanism.

[0056] A box sheet pressing rod 412 is provided on the box pressing base plate 41. The box sheet pressing rod 412 is used to limit the box sheet on the side of the carton so that the box sheet on the side of the carton is tightly attached to the carton body.

[0057] A first roller assembly 43 is provided on the pressing base plate 41. The first roller assembly 43 includes a first roller seat, a first unpowered roller, and a roller drive 42. The roller drive 42 has a fixed end and a telescopic end. The fixed end of the roller drive 42 is connected to the pressing base plate 41, and the telescopic end of the roller drive 42 is connected to the first roller seat. A plurality of the first unpowered rollers are linearly arrayed on the first roller seat. The first unpowered rollers are used to limit the side panel connection of the carton so that the side panel connection of the carton is tightly attached to the carton body.

[0058] The sealing assembly 20 also includes a second roller assembly 27, which includes a roller adjusting frame, a roller seat fixing plate, a second roller seat, and a second unpowered roller.

The second roller seat is fixed to the roller seat fixing plate, and a plurality of second unpowered rollers are linearly arranged in the second roller seat. The second unpowered rollers are used to contact the outside of the carton and limit the outside of the carton.

[0059] The tail sealing mechanism 80 has the same structure as the head sealing mechanism. The two are positioned opposite each other on both sides of the sealing station 90 to automatically seal the sides of the carton with tape. The specific shape and fixed position of the tape roller mounting plate 11 of the tail sealing mechanism 80 and the head sealing mechanism can be adjusted according to the overall layout and clearance requirements of the carton sealing machine. This will be understood by those skilled in the art and will not be elaborated here.

[0060] In this embodiment, the electric sealing tape device installs the box head sealing mechanism and the box tail sealing mechanism 80 on both sides of the carton conveying channel of the carton sealing machine. The box head sealing mechanism and the box tail sealing mechanism 80 are respectively equipped with a tape supply component 10 and a sealing component 20. The tape supply drive component 14 provides power, and the power is transmitted to the tape through the tape supply drive roller 13, thereby providing power to the sealing tape. This ensures that the tape is released smoothly and avoids poor adhesion or breakage due to uneven tension, thus significantly improving the sealing efficiency.

[0061] Several winding rollers are set on the conveyor belt mounting plate 11 to provide guidance for the conveyor belt to wind around; a tension roller 15 is set, the end of which is rotatably connected to the conveyor belt mounting plate 11 through a tensioning elastic element 16, and the position of the tension roller 15 is sensed by a tensioning sensor 18 to determine the tension of the conveyor belt, thereby realizing the acceleration or deceleration control of the conveyor belt drive 14 to achieve the purpose of flexible conveyor belt supply; the remaining amount of sealing conveyor belt is detected by a residual amount sensor 19. When the residual amount is too low, the system will trigger an alarm prompt, and the conveyor belt will be replaced manually.

[0062] By installing the adjustment components 30 of the box head sealing mechanism and the box tail sealing mechanism 80 on both sides of the packing station, the width adjustment handwheel 321 and the height adjustment handwheel 211 rotate the corresponding width adjustment screw assembly or height adjustment screw, so that the trapezoidal nut of the adjustment screw moves linearly on the trapezoidal screw. The self-lubricating graphite copper sleeves sleeved on each guide rod provide guidance and support, so that the relative displacement occurs between the adjustment frame 31, the adjustment base plate 32, and the sealing base plate 21 connected by the trapezoidal nut and the guide rod, thereby realizing the adjustment of the sealing width position and the sealing height position to meet the usage conditions of cigarette boxes of various specifications. The carton pressing assembly 40 provides a guiding function for the carton as it enters the sealing station 90; the first roller assembly 43, controlled by a cylinder, moves away from the carton before it enters the working range of each carton pressing bar 412, facilitating the carton's entry into the working range of the pressing bars 412, and moves closer to the carton after it enters the working range of the pressing bars 412, thus supporting the carton and preventing the carton from opening automatically; the side guide plate 26 provides guidance during the carton's ascent while pressing the tape to prevent damage to the carton due to insecure tape sealing; the second roller assembly 27 is installed on the outside of the sealing machine frame 22, and provides guidance and support to the unsealed side of the carton during the sealing process of the sealing assembly 20, ensuring the carton rises smoothly and improving the sealing quality.
