Detailed Embodiment

[0020] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0021] Embodiments of the present utility model: As Figures 1-6 shown, a novel automatic water transfer paper width adjusting device for ZJ17 cigarette making machine includes a water transfer paper support assembly, a main shaft 1, a spring 2, a push plate 3 and a push plate driving device. The water transfer paper support assembly is movably installed on the main shaft 1. One end of the main shaft 1 is fixedly provided with a mounting plate 4. The spring 2 is sleeved on the main shaft 1. One end of the spring 2 abuts against the mounting plate 4, and the other end of the spring 2 abuts against the water transfer paper support assembly. The other end of the main shaft 1 is threadedly connected to one end of an adjusting screw rod 5, and the other end of the adjusting screw rod 5 is fixedly connected to the push plate 3. The push plate 3 is connected to the push plate driving device.

[0022] The main shaft 1 is fixed to the frame of the splicer through the mounting plate 4. The spring 2 functions to push the water transfer paper support assembly, and the spring 2 always provides a thrust to the water transfer paper support assembly. The push plate 3 generates rotation and axial displacement under the action of the push plate driving device. When the push plate 3 approaches the mounting plate 4, it pushes the water transfer paper support assembly to move in the direction close to the mounting plate 4. When the push plate 3 moves in the direction away from the mounting plate 4, under the action of the spring 2, the water transfer paper support assembly moves in the direction away from the mounting plate 4, thereby realizing the change of the position of the water transfer paper 31, thereby adjusting the relative position between the water transfer paper and the cutter, and changing the width of the water transfer paper after being cut by the cutter.

[0023] In a specific embodiment, the water transfer paper support assembly includes an adjusting shaft 6, a middle water transfer paper support block 7, a first paper edge adjusting block 8 and a second paper edge adjusting block 9. The adjusting shaft 6 is movably sleeved on the main shaft 1. The middle water transfer paper support block 7 is fixedly connected to the adjusting shaft 6. The first paper edge adjusting block 8 and the second paper edge adjusting block 9 are both movably installed on the adjusting shaft 6. The first paper edge adjusting block 8 and the second paper edge adjusting block 9 are located on both sides of the middle water transfer paper support block 7. An adjusting assembly is provided on the middle water transfer paper support block 7, and the adjusting assembly is threadedly connected to the first paper edge adjusting block 8 and the second paper edge adjusting block 9.

[0024] The adjusting shaft 6 is a circular tubular structure. The adjusting shaft 6 is sleeved on the main shaft 1 and can move on the main shaft 1. The middle water transfer paper support block 7 is fixed in the middle of the adjusting shaft 6. The first paper edge adjusting block 8 and the second paper edge adjusting block 9 are of symmetrical structure. By adjusting the distance between the first paper edge adjusting block 8 and the second paper edge adjusting block 9 through the adjusting assembly, the water transfer paper support assembly can support water transfer papers of different specifications, improving the versatility of the equipment.

[0025] Specifically, the middle support block 7 of the tipping paper has a first mounting hole 10 and a second mounting hole 11. The adjusting shaft 6 is inserted and connected to the first mounting hole 10. A first threaded hole 12 is formed on one side of the middle support block 7 of the tipping paper. The first threaded hole 12 communicates with the first mounting hole 10, and the first threaded hole 12 is perpendicular to the first mounting hole 10. A locking screw 13 is threadedly connected in the first threaded hole 12.

[0026] After the middle support block 7 of the tipping paper is mounted on the adjusting shaft 6 through the first mounting hole 10, it is moved to the middle position of the adjusting shaft 6, and then the locking screw 13 is rotated. The end of the locking screw 13 is conical. By the abutment of the locking screw 13 against the outer wall of the adjusting shaft 6, the middle support block 7 of the tipping paper is fixed on the adjusting shaft 6. As can be seen from the drawings, the top surface of the middle support block 7 of the tipping paper has an arc-shaped support surface and a horizontal support surface.

[0027] Further, the adjusting assembly includes an intermediate shaft 14, a first threaded rod 15, and a second threaded rod 16. The two ends of the intermediate shaft 14 are respectively rotatably connected to the first threaded rod 15 and the second threaded rod 16. One-shaped grooves 17 are formed at the ends of the first threaded rod 15 and the second threaded rod 16 away from the intermediate shaft 14. The intermediate shaft 14 is press-fitted into the second mounting hole 11.

[0028] The axis of the second mounting hole 11 is parallel to the axial direction of the first mounting hole 10. The adjusting assembly is horizontally arranged. By making the intermediate shaft 14 and the second mounting hole 11 in interference fit, the adjusting assembly is fixed on the middle support block 7 of the tipping paper.

[0029] Further, the first paper edge adjusting block 8 has a third mounting hole 18 and a second threaded hole 19. The adjusting shaft 6 is inserted and connected to the third mounting hole 18. The first threaded rod 15 is threadedly connected to the second threaded hole 19. A first limiting boss 20 is formed on the top surface of the first paper edge adjusting block 8.

[0030] The second threaded hole 19 is coaxially arranged with the second mounting hole 11. By rotating the first threaded rod 15, the first paper edge adjusting block 8 can be moved on the adjusting shaft 6. The first limiting boss 20 plays a limiting role to prevent the tipping paper 31 from running off to one side. Similar to the middle support block 7 of the tipping paper, the top surface of the first paper edge adjusting block 8 has an arc-shaped support surface and a horizontal support surface.

[0031] Further, the second paper edge adjusting block 9 has a fourth mounting hole 21 and a third threaded hole 22. The adjusting shaft 6 is inserted and connected to the fourth mounting hole 21. The second threaded rod 16 is threadedly connected to the third threaded hole 22. A second limiting boss 23 is formed on the top surface of the second paper edge adjusting block 9.

[0032] The second limiting boss 23 is used to limit the other side of the tipping paper 31 to prevent deviation. The third threaded hole 22 is coaxially arranged with the second mounting hole 11. By the cooperation of the second threaded rod 16 and the third threaded hole 22, when the second threaded rod 16 rotates, the second paper edge adjusting block 9 moves on the adjusting shaft 6. The top surface of the second paper edge adjusting block 9 also has an arc-shaped supporting surface and a horizontal supporting surface.

[0033] The tipping paper middle supporting block 7, the first paper edge adjusting block 8 and the second paper edge adjusting block 9 jointly support the tipping paper 31. The first limiting boss 20 and the second limiting boss 23 are used to limit the two sides of the tipping paper 31. By changing the distance between the first paper edge adjusting block 8 and the second paper edge adjusting block 9, the utility model is applicable to tipping papers of different specifications.

[0034] Furthermore, proximity switch mounting holes 24 are formed on both the first limiting boss 20 and the second limiting boss 23, and the proximity switches 25 are plugged and connected with the proximity switch mounting holes 24.

[0035] The proximity switches 25 adopt photoelectric switches. The proximity switches 25 are fixedly arranged on the frame of the cigarette tipping machine. The two proximity switches 25 are used to detect the positions of the two sides of the tipping paper 31.

[0036] Moreover, the push plate driving device includes a servo motor 26, a driving wheel 27, a driven toothed belt wheel 28 and a toothed belt 29. A toothed belt wheel mounting shaft 30 is formed on the push plate 3. The driven toothed belt wheel 28 is fixedly mounted on the toothed belt wheel mounting shaft 30. The driving wheel 27 is fixedly mounted on the output shaft of the servo motor 26. The driving wheel 27 is connected with the driven toothed belt wheel 28 through the toothed belt 29.

[0037] Working principle of the utility model: Before the equipment runs, first rotate the first threaded rod 15 and the second threaded rod 16 according to the width of the tipping paper, and change the distance between the first paper edge adjusting block 8 and the second paper edge adjusting block 9, so as to effectively support and limit the tipping paper 31. It should be noted that the servo motor 26 and the two proximity switches 25 of the utility model are both electrically connected to the PLC programmable controller of the cigarette making and tipping machine. During operation, when the cigarette making and tipping machine detects that the widths of the cut tipping paper are not equal, the distance that the tipping paper support assembly should be adjusted is calculated through the program in the PLC programmable controller, and then the PLC programmable controller controls the servo motor 26 to work. The servo motor 26 transmits power to the driven toothed belt pulley 28 through the toothed belt 29, and the driven toothed belt pulley 28 drives the push plate 3 to rotate. The adjusting screw rod 5 fixedly connected to the push plate 3 is in threaded cooperation with the threaded hole in the main shaft 1. Since the main shaft 1 is fixed on the frame of the cigarette making and tipping machine, the main shaft 1 is fixed and immovable, while the push plate 3 will generate an axial displacement. The generation of the axial displacement of the push plate 3 causes the tipping paper support assembly to generate an axial displacement on the main shaft 1. The two proximity switches 25 are fixed and immovable, and they detect the distances from the two side edges of the tipping paper 31 to the proximity switches 25 in real time, so that the PLC programmable controller calculates the moving distance of the tipping paper 31, that is, the moving distance of the tipping paper support assembly. When the tipping paper support assembly reaches the target distance, the servo motor 26 is controlled to stop working. At this time, the widths of the tipping paper cut by the cutter are equal.

[0038] The structure, features and action effects of the utility model have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the utility model, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and the drawings, shall be within the protection scope of the utility model.
