[0032] Embodiment 1
[0033] As Figures 1-7 The utility model discloses a cigarette machine is with paddle, including paddle body 10 and install in the heating assembly of paddle body 10, heating assembly includes first heating pipe 11 and second heating pipe 12, the diameter of first heating pipe 11 is 12.5mm, the diameter of second heating pipe 12 is 10.5mm, first heating pipe 11 sets up at the bottom end of paddle body 10, first heating pipe 11 distance paddle body 10's bottom end surface 16mm, distance paddle body 10 back 9.5mm, second heating pipe 12 sets up in the middle part of paddle body 10 and is adjacent to first heating pipe 11, second heating pipe 12 distance paddle body 10's bottom end surface 30mm, distance paddle body 10 back 7.5mm, the power of first heating pipe 11 and second heating pipe 12 is identical, for example: the power of first heating pipe 11 and second heating pipe 12 is 500W, still install temperature sensor 13 in paddle body 10, temperature sensor 13 uses platinum resistance, the diameter of platinum resistance is 7mm, and platinum resistance installs in the side of second heating pipe 12 away from first heating pipe 11, platinum resistance distance paddle body 10's bottom end surface 45mm, distance paddle body 10 back 7.5mm. by the first heating pipe 11 and second heating pipe 12 of power 500W to the heating of paddle body 10, replace the heating mode of the single heating pipe of original 1200W, can make the heat transfer of paddle body 10 more uniform, realizes more balanced heating, simultaneously, under the condition that the same heating effect is obtained, total heating power consumption reduces, saves the energy, energy saving and environmental protection.
[0034] Thus, when the cigarette machine is running at high speed, the temperature sensor 13 can be prevented from being affected by the large temperature difference between the head and tail of the paddle body 10 caused by the heat of the paddle body 10 being taken away by the high-speed running of the rubbing wheel corresponding to the paddle body 10, and the large fluctuation of the temperature sensor 13 can be prevented from affecting the detection of the temperature sensor 13. The double-tube uniform heating maintains the temperature of the paddle body 10 stable and uniform, improves the rubbing quality, and has high practicability.
[0035] As Figure 1As shown, in this embodiment, the side of the rubbing board body 10 that contacts the tipping paper is configured as a rubbing section with an arc surface. The rubbing section includes two first sub-rubbing sections 15 and one second sub-rubbing section 16, with the second sub-rubbing section 16 positioned between the two first sub-rubbing sections 15. In this embodiment, the arc radii of the first sub-rubbing sections 15 and the second sub-rubbing section 16 are different. The arc radius of the first sub-rubbing section 15 is 136.2 ± 0.1 mm, corresponding to a bottom width of 24.5 mm and a top width of 13.6 mm for the rubbing board body 10. The arc radius of the second sub-rubbing section 16 is 135.8 ± 0.1 mm, corresponding to a bottom width of 24.1 mm and a top width of 13.2 mm for the rubbing board body 10. This rubbing section design adapts to the running trajectory of the rubbing roller, maintaining the rubbing quality of the tipping paper.
[0036] In practice, when selecting the specifications of the joint, the arc radii of the first sub-joint 15 and the second sub-joint 16 can be the same, both being 136.2±0.1mm. Other size ranges can also be selected as needed. For example, in this embodiment, the arc radii of the first sub-joint 15 and the second sub-joint 16 are both selected to be 135.8±0.1mm; or, both can be 136.0±0.1mm.
[0037] In the above embodiment, the contact surface height B between the first sub-joint 15 and the tipping paper is 0.4 mm lower than the contact surface height A between the second sub-joint 16 and the tipping paper. This structural design, through the design of the first sub-joint 15 and the second sub-joint 16 with varying heights, can prevent the joint edge from carrying the cigarette off-center during the contact with the tipping paper, thereby improving the jointing quality.
[0038] like Figure 3 , Figure 5 As shown, in this embodiment, the washboard body 10 includes a mounting bracket 19, which has mounting holes. The first sub-washboard joint 15 and the second sub-washboard joint 16 are mounted on the mounting bracket 19 by screws and mounting holes. This structural design allows the first sub-washboard joint 15 and the second sub-washboard joint 16 to be disassembled and replaced when wear exceeds the limit, thus reducing the cost of using the structure.
[0039] like Figure 1 , Figure 4 As shown, in this embodiment, the top back of the washboard body 10 is set as an inclined surface 14, through which it can contact the return wheel or other structures.
[0040] In this embodiment, the side of the rubbing board body 10 that contacts the tipping paper is provided with contact teeth 18 to form a rubbing joint; the vertical height difference between the top end face of the rubbing board body 10 and its arc center is 17mm.
[0041] likeFigure 4 As shown, the top of the side of the platen body 10 in contact with the tipping paper is provided with a smooth contact surface 20; the height of the smooth contact surface 20 is L1, and the specific value is 10 mm; the side of the platen body 10 in contact with the tipping paper protrudes from the edges of the two ends of the platen body 10 by a distance L2, and the specific value is 0.75 mm. With such a structural design, the part without contact teeth, i.e. the smooth contact surface 20, can make the transition of the tail of the platen body 10 and the tipping paper more smooth, so as to not increase the possibility of generating smoke due to sudden changes.
[0042] As shown in the drawings, Figures 5-7 In this embodiment, the platen body 10 is provided with heat transfer holes 17 in the region between the first heating pipe 11 and the second heating pipe 12, and different heat transfer media are formed between the heat transfer holes 17 and the platen body 10. In this embodiment, the number of heat transfer holes 17 is five, and the shape is a special-shaped hole in the shape of a circular truncated cone. Generally, the material of the platen body 10 is 45 steel; compared with the special-shaped hole, the steel material has faster heat transfer. In this way, by adding the special-shaped hole, the difference in the heat transfer coefficients of different media can be utilized to avoid the temperature transfer between the first heating pipe 11 and the second heating pipe 12 being too concentrated, so as to adjust the uniformity of the temperature transfer of the platen body 10 when the first heating pipe 11 and the second heating pipe 12 heat the platen body 10, reduce the local temperature difference, and thus improve the heating uniformity of the platen body 10.
[0043] As shown in the drawings, Figure 6 , Figure 7 In this embodiment, the actual heat transfer holes 17 can be designed as seven, ten or other numbers of special-shaped holes, and can be flexibly designed as needed in application. The cross-sectional shape of the heat transfer holes in this embodiment is a trapezoidal shape.
[0044] As shown in the drawings, Figure 6 , Figure 7 In this embodiment, the size of the first heating pipe 11 is larger than that of the second heating pipe 12; the opening size of the heat transfer hole close to one end of the second heating pipe 12 is smaller than that of the other end. Such a structural design can correspond to the structure size of the platen body 10, which is small at the top and large at the bottom, is beneficial to balanced heat conduction, reduces the heat transfer concentrated between the first heating pipe 11 and the second heating pipe 12, and at the same time, since the special-shaped hole is a cavity with lower heat conduction than steel itself, the heat transfer between the region of the first heating pipe 11 and the second heating pipe 12 can be better isolated, indirectly balancing the heating of the platen body 10.
[0045] The structure design, on the basis of the existing rolling plate, the first heating pipe 11 and the second heating pipe 12 arranged in the rolling plate body 10 can balance the heating of the rolling plate; the temperature sensor 13 can have small temperature fluctuation of the rolling plate when detecting the temperature, and has high robustness; meanwhile, the total heating energy consumption is reduced by nearly 17%, which is more energy-saving and environment-friendly, and is helpful to popularization; the overall structure of the device is relatively simple, convenient to install, and has high practicability.
[0046] The rolling plate for a cigarette machine is described in detail. The description of the specific embodiments is only used to help understand the method and the core idea of the rolling plate. It should be pointed out that, for ordinary skilled persons in the art, without departing from the principle of the rolling plate, the rolling plate can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the rolling plate.
