[0028] Working process: 1) Regarding the width of the unsealed cigarette box, first adjust the first movable adjustable component to move closer to or further away from the first support, so that the distance between the carton contact adjustable component on the first movable adjustable component and the carton flaring adjustable component on the first support, the distance between the second lifting and folding component on the first movable adjustable component and the first lifting and folding component on the first support, and the distance between the fourth lifting and folding component on the first movable adjustable component and the third lifting and folding component located on the first support are suitable for the width of the unsealed cigarette box. Then adjust the second movable adjustable component to move closer to the first support. The distance between the second adjustable lifting roller on the second movable adjustable component and the first adjustable lifting roller on the first support, the distance between the sixth adjustable lifting folding component on the second movable adjustable component and the fifth adjustable lifting folding component on the first support, the distance between the sixth adjustable lifting folding component connected to the moving end of the second adjustable lifting roller and the fifth adjustable lifting folding component on the first support, and the distance between the second adjustable lifting sealing assembly on the second movable adjustable component and the first adjustable lifting sealing assembly on the first support are suitable for the width of the unsealed cigarette box;

[0029] 2) Next, regarding the height of the unsealed cigarette box, adjust the height of the first lifting and folding component on the first support and the second lifting and folding component on the second support, the height of the carton flaring adjustable component on the first support and the carton abutting adjustable component on the second support, the height of the carton flaring adjustable component on the first support and the carton abutting adjustable component on the second support, the height of the third lifting and folding component on the first support and the fourth lifting and folding component on the second support, the height of the first lifting pressure roller adjustable component on the first support and the second lifting pressure roller adjustable component on the second support, the height of the fifth lifting and folding component on the first support and the sixth lifting and folding component on the second support, and the height of the first lifting and folding sealing component on the first support and the second lifting and folding sealing component on the second support to suit the height of the unsealed cigarette box.

[0030] 3) After the above adjustments are completed, first use the suction cup connected to the robotic arm to put the unsealed cigarette box at both ends into the carton placement suction device in the conveying channel and suction the two push arms located in the cigarette box push assembly. Then, make one open end of the cigarette box fit into the flared end of the carton flaring adjustable assembly in the expanded state and make the abutting end of the carton abutting adjustable assembly abut into the other open end of the cigarette box. Then push the five-layer cigarette stack from the carton flaring adjustable assembly into the cigarette box fitted with the flared end of the carton flaring adjustable assembly.

[0031] 4) After the tobacco stack enters the tobacco box with both ends open, first make the adjustable carton flaring component move to the retracted state (the flaring end of the adjustable carton flaring component is in the retracted state to facilitate the tobacco box to detach from the flaring end of the adjustable carton flaring component) and make the contact end of the adjustable carton contact component retract to no longer contact the tobacco box. Then, make the folding ends of the first lifting folding component and the third lifting folding component, which are close to the flaring end of the adjustable carton flaring component, extend simultaneously to pre-fold the two wings on one open end of the tobacco box that are close to the flaring end of the adjustable carton flaring component. At the same time, the folding ends of the second lifting folding component and the fourth lifting folding component, which are far away from the flaring end of the adjustable carton flaring component, pre-fold the two wings on the other open end of the tobacco box that are far away from the flaring end of the adjustable carton flaring component.

[0032] 5) After the above folding process is completed, first make the carton placement adsorption component no longer adsorb to the cigarette box containing the cigarette stack, then drive the cigarette box pushing component in the conveying channel to carry the cigarette box containing the cigarette stack through the third and fourth lifting adjustable folding components, the fifth and sixth lifting adjustable folding components, the first and second lifting adjustable pressure roller components, and the first and second lifting adjustable sealing components in sequence. The third and fourth lifting adjustable folding components first press down on the upper and lower side wings at the two open ends of the cigarette box, which are in the open state. The fifth and sixth lifting adjustable folding components continue to press down on the upper and lower side wings at the two open ends of the cigarette box. The first and second lifting adjustable pressure roller components then press down on the upper part of the cigarette box and the upper and lower side wing seams at the open ends of the cigarette box. The first and second lifting adjustable sealing components then seal the upper and lower side wing seams at the open ends of the cigarette box.

[0033] 6) During the sealing process of the upper and lower side wing seams at the open ends of the cigarette box by the first and second adjustable sealing components, if the tape tension in the first and second adjustable sealing components is too tight and is detected, the first and second adjustable sealing components will compensate for the tape tension in the first and second adjustable sealing components to prevent the tape tension in the first and second adjustable sealing components from breaking due to excessive tightness.

[0034] 7) After the upper and lower side wing seams of the two open parts of the cigarette box are sealed with adhesive, the cut ends of the first and second adjustable sealing components cut the transparent tape. The sealed cigarette box with the cigarette stack leaves the sealing machine through the discharge end of the conveying channel to complete the sealing process of cigarette boxes of different sizes.

[0035] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0036] 1. This utility model relates to an adjustable flexible carton sealing mechanism comprising a frame, a cigarette box pushing component, a carton flaring adjustable component, a carton placement suction component, a first fold adjustable component, a second fold adjustable component, a pressure roller adjustable group, a third fold adjustable component, and a sealing component with compensation function. This mechanism allows for the adjustment of the carton flaring adjustable component, carton placement suction component, first fold adjustable component, second fold adjustable component, pressure roller adjustable group, third fold adjustable component, and sealing component with compensation function within the flexible carton sealing mechanism when sealing cigarette boxes of different heights and widths. This satisfies the need to seal cartons of different heights and widths, thereby solving the problem that existing carton sealing machines cannot seal cartons of different heights and widths.

[0037] 2. This utility model integrates a tape supply mechanism with compensation function, comprising a tape reel, a tape compensation component, a tape tension guide component, a tape tension monitoring component, and a base plate. The tape tension over-tightness detector and the tape tension normality detector in the tape tension monitoring component are located within the swing range of the tension swing arm in the tape tension guide component. The tension swing arm is in active contact with the tape tension over-tightness detector and the tape tension normality detector, respectively. The tape tension over-tightness detector and the tape tension normality detector are electrically connected to the tape compensation motor through a controller. When the tension swing arm swings to the point where the tape tension over-tightness detector detects that the tape is too tight, the tape tension over-tightness detector will drive the tape compensation guide wheel with tape wound on it to rotate through the controller tape compensation motor, thereby releasing a portion of the tape on the tape reel, thus relieving the tension of the tape and preventing the tape from being pulled apart due to excessive tightness.

[0087] In practical applications, when using a flexible carton sealing machine to seal cigarette cartons of different specifications, for the width of the unsealed cigarette cartons, first adjust the first movable adjustable component 9 to move closer to or further away from the first support 5, so that the distance between the carton contact adjustable component 4 on the first movable adjustable component 9 and the carton flaring adjustable component 7 on the first support 5, the distance between the second lifting and folding component 15 on the first movable adjustable component 9 and the first lifting and folding component 14 on the first support, and the distance between the fourth lifting and folding component 20 on the first movable adjustable component 9 and the third lifting and folding component 19 located at the first support 5 are suitable for the width of the unsealed cigarette cartons. Then adjust the second movable adjustable component 25 towards the first support 5. A bracket 5 moves closer to or further away from the first bracket 5, such that the distance between the second lifting pressure roller adjustable member 24 on the second movable adjustable member 25 and the first lifting pressure roller adjustable member 23 on the first bracket 5, the distance between the sixth lifting adjustable folding member 28 on the second movable adjustable member 25 and the fifth lifting adjustable folding member 27 on the first bracket 5, the distance between the sixth lifting adjustable folding member 28 connected to the moving end of the second lifting pressure roller adjustable member 24 and the fifth lifting adjustable folding member 27 located on the first bracket 5, and the distance between the second lifting adjustable sealing assembly 31 on the second movable adjustable member 25 and the first lifting adjustable sealing assembly located on the first bracket 5 are suitable for the width of the unsealed cigarette box;

[0088] Next, regarding the height of the unsealed cigarette box, adjust the height of the first lifting and folding component 14 on the first bracket 5 and the second lifting and folding component 15 on the second bracket 5, the height of the carton flaring adjustable component 7 on the first bracket 5 and the carton abutment adjustable component 7 on the second bracket 5, the height of the carton flaring adjustable component 7 on the first bracket 5 and the carton abutment adjustable component 7 on the second bracket 6, the height of the third lifting and folding component 19 on the first bracket 5 and the fourth lifting and folding component 20 on the second bracket 6, the height of the first lifting pressure roller adjustable component 23 on the first bracket 5 and the second lifting pressure roller adjustable component 24 on the second bracket 6, the height of the fifth lifting and folding component 27 on the first bracket 5 and the sixth lifting and folding component 28 on the second bracket 6, and the height of the first lifting and folding sealing component 27 on the first bracket 5 and the second lifting and folding sealing component 28 on the second bracket 6 to suit the height of the unsealed cigarette box.

[0089] After the above adjustments are completed, first use the suction cup connected to the robotic arm to put the unsealed cigarette box into the carton placement suction component 10 in the conveying channel 2 and suction the two push arms 12 located in the cigarette box push component 11. Then, make one open end of the cigarette box fit with the flared end of the carton flaring adjustable component 7 which is in an expanded state, and make the abutting end of the carton contact adjustable component 8 contact the other open end of the cigarette box. Then push the five-layer cigarette stack from the carton flaring adjustable component 7 into the cigarette box fitted with the flared end of the carton flaring adjustable component 7.

[0090] After the tobacco stack enters the tobacco box with open ends, the carton flaring adjustable component 7 is first moved to a retracted state (the flaring end of the carton flaring adjustable component is in a retracted state to facilitate the separation of the tobacco box from the flaring end of the carton flaring adjustable component) and the carton contact adjustable component contact end is retracted to no longer contact the tobacco box. Then, the folding ends of the first lifting folding piece 14 and the third lifting adjustable folding piece 15, which are close to the flaring end of the carton flaring adjustable component 7, are simultaneously extended to pre-fold the two wings on one open end of the tobacco box that are close to the flaring end of the carton flaring adjustable component 7. At the same time, the folding ends of the second lifting folding piece 15 and the fourth lifting adjustable folding piece 20, which are far away from the flaring end of the carton flaring adjustable component 7, are pre-folded toward the two wings on the other open end of the tobacco box that are far away from the flaring end of the carton flaring adjustable component 7.

[0091] After the above folding process is completed, first, ensure that the cardboard box placement adsorption component no longer adsorbs onto the cigarette box containing the cigarette stacks. Then, drive the cigarette box pushing component in the conveyor channel 2 to carry the cigarette box containing the cigarette stacks sequentially between the third adjustable folding component 19 and the fourth adjustable folding component 20, between the fifth adjustable folding component 27 and the sixth adjustable folding component 28, between the first adjustable lifting pressure roller component 23 and the second adjustable lifting pressure roller component 24, and between the first adjustable sealing assembly 27 and the second adjustable sealing assembly 28. The third adjustable folding component... The stacked component 19 and the fourth adjustable folding component 20 first press down on the upper and lower side wings at the two open ends of the cigarette box, which are in the open state. The fifth adjustable folding component 27 and the sixth adjustable folding component 28 continue to press down on the upper and lower side wings at the two open ends of the cigarette box. The first adjustable lifting roller component 23 and the second adjustable lifting roller component 24 then press down on the upper part of the cigarette box and the joints of the upper and lower side wings at the open ends of the cigarette box. The first adjustable sealing component 30 and the second adjustable sealing component 31 then seal the joints of the upper and lower side wings at the open ends of the cigarette box.

[0092] During the sealing process of the upper and lower side wing seams at the open ends of the cigarette box by the first adjustable sealing assembly 30 and the second adjustable sealing assembly 31, if the excessive tension of the tape in the first adjustable sealing assembly 30 and the second adjustable sealing assembly 31 is detected, both the first adjustable sealing assembly 30 and the second adjustable sealing assembly 31 will compensate for the tape tension in both components to prevent the tape from breaking due to excessive tension.

[0093] After the upper and lower side wing seams of the two open parts of the cigarette box are sealed with adhesive, the cut ends of the first adjustable sealing component 30 and the second adjustable sealing component 31 cut the transparent tape. The sealed cigarette box with the cigarette stack leaves the sealing machine through the discharge end of the conveying channel to complete the sealing process of cigarette boxes of different sizes, thereby solving the problem that the existing sealing machine cannot seal cartons of different heights and widths.

The side wall of the movable seat 145 is connected, and the bottom of the first rotating seat 145 is rotatably connected to the top of the base plate 136. One end of the first support arm 146 connected to the side wall of the first rotating seat 145 is connected to one end of the first tension spring 143, and the other end of the first tension spring 143 is connected to the third connecting post connected to the upper part of the base plate 136. There is an angle between the first tension spring 143 and the tension swing arm 144. The tape tension monitoring device 147 is located within the swing range of the tension swing arm 144. The tape tension monitoring device 147 includes a tape tension over-tightness detector 148 and a tape tension normality detector 149. The tape tension over-tightness detector 148 and the tape tension normality detector 149 are respectively connected to the tape tension compensation device via a controller. The motor 140 is electrically connected. The tape tension over-tightness detector 148 and the tape tension normalness detector 149 are located within the swing range of the tension swing arm 144. The tension swing arm 144 is in active contact with the tape tension over-tightness detector 148 and the tape tension normalness detector 149 respectively.

One end of the third arm 153, which is connected to the side wall of the second rotating seat 152, is connected to one end of the second tension spring 154. The other end of the second tension spring 154 is connected to the fourth connecting post 155, which is connected to the upper part of the base plate 136.

[0115] In practical applications, when using a tape supply mechanism with a compensation function to seal a cigarette box containing cartons of cigarettes, the transparent roll of tape for sealing the cigarette box is first attached to the tape reel 135. The starting end of the transparent tape is then wound around the tape compensation guide wheel 141 and the tension guide wheel 142 until it is adhered to the tape suction cup baffle 150, ready for subsequent sealing of the cigarette box containing cartons of cigarettes. When the cigarette box containing cartons of cigarettes that needs to be sealed passes the tape suction cup baffle 150, the transparent tape adsorbed on the tape suction cup baffle 150 adheres to the moving part of the box. At the seam of the side wall of the cigarette box, as the cigarette box continues to move forward, it pushes against the tape suction cup baffle 150 while continuing to move forward with the adhered tape. During this process, the tape is tightened, and the tape tension changes. Under this tension, the tension swing arm 144, connected to the tension guide wheel 142, swings between the tape tension over-tightness detector 148 and the tape tension normality detector 149 to relieve the tape tension. During the swinging process between the belt tension over-tension detector 148 and the belt tension normal detector 149, if the tension swing arm 144 swings to the belt tension normal detector 149 and comes into contact with it, the belt tension normal detector 149 will not control the belt compensation motor 140 to drive the belt compensation guide wheel 141 to rotate, thus keeping the belt tension within the normal range; if the tension swing arm 144 swings to the belt tension over-tension detector... The device 148 is in contact with the tape tension detector 148. The tape tension over-tightness detector 148 controls the tape compensation motor 140 through the controller to drive the tape compensation guide wheel 141 to rotate. This drives the transparent tape wound on the tape compensation guide wheel 141 to rotate, releasing a section of the transparent roll tape wound on the tape reel 135 in a short time. This relieves the tension of the tape and prevents the tape from breaking due to excessive tension. This solves the problem of the tape being pulled apart in the sealing machine during the sealing of cigarette boxes.

[0116] It should be noted that the over-tight tape detector 148 and the normal tape tension detector 149 are existing sensors that detect when the tape tension is in place. The over-tight tape detector 148 and the normal tape tension detector 149 can also be limit switches. These are existing technologies, and no improvements or designs have been made to them. Therefore, their structures will not be described in detail.
