Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and in particular to an adsorption-fixed cigar tobacco leaf flattening device and a use method thereof. Background Art

[0002] Because air-cured cigar tobacco leaves have poor toughness and a low moisture content of only 20% to 22%, they curl under surface tension, ultimately shrinking into slender strips 43cm long. To enable subsequent stacking and fermentation processes, the leaves need to be repeatedly unfolded and rolled until they are fully expanded, approximately 25cm horizontally and 45cm vertically. This process has a critical impact on subsequent fermentation and the sensory quality of the cigar leaves. Furthermore, due to the thinness of cigar leaves and the individual differences between each leaf, the unfolding operation is performed manually in both domestic and international production, resulting in low production efficiency and high labor input.

[0003] The manual spreading process involves placing the tobacco leaves on a smooth, turtle-back-shaped wooden board, then repeatedly spreading them out by hand, one leaf at a time, compacting the edges and stacking them. This repetitive process requires repeated flattening of each leaf, making it labor-intensive, inefficient, and tedious. Due to rising labor costs, the high labor input required in the cigar tobacco spreading process has hindered the profitability of cigar tobacco cultivation.

[0004] Therefore, there is an urgent need to develop a device that can flatten cigar tobacco leaves in production, so as to mechanize the cigar tobacco leaf spreading process, greatly improve the cigar tobacco leaf spreading efficiency, reduce labor input, reduce labor production costs, and improve the comprehensive economic benefits of cigar tobacco planting.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0019] like Figure 1 As shown, on the one hand, an embodiment of the present invention provides an adsorption-fixed cigar tobacco leaf M flattening device, comprising a negative pressure conveying component 100, a flattening component 200 and a humidifying component 300. The negative pressure conveying component 100 has an adsorption conveying surface for adsorbing and conveying tobacco leaves M. The flattening component 200 includes a fixing part 210 and a flexible flattening part 220 arranged in sequence along the conveying direction of the adsorption conveying surface and movably connected to the negative pressure conveying component 100. The fixing part 210 can be moved to a position for pressing the tobacco leaves M on the adsorption conveying surface to fix the tobacco leaves M. The flexible flattening part 220 can be moved to a position close to the tobacco leaves M on the adsorption conveying surface and can be rotated along its axial direction to flexibly contact and flatten the tobacco leaves M. The humidifying component 300 has a humidifying end arranged directly above the adsorption conveying surface. The humidifying end is arranged at a position between the fixing part 210 and the feeding end of the negative pressure conveying component 100.

[0020] During implementation, the tobacco leaves M are adsorbed on the negative pressure conveying component 100 under the action of negative pressure. As the negative pressure conveying component 100 conveys, the humidifying component 300 first humidifies the tobacco leaves M. The humidified tobacco leaves M have better flexibility and are more conducive to spreading. Subsequently, the fixing part 210 fixes the tobacco leaves M, and the flexible flattening part 220 is in flexible contact with the tobacco leaves M. The flexible contact prevents the tobacco leaves M from being damaged during the flattening process, and flattens the tobacco leaves M by squeezing and rotating, replacing manual operation, saving time and effort.

[0021] The negative pressure conveying component 100 in this embodiment has a suction conveying surface for sucking and conveying tobacco leaves M.

[0022] like Figure 6 As shown, in one embodiment, the negative pressure delivery assembly 100 includes a frame 110, a conveyor belt 120, a negative pressure box 130 and a negative pressure member 140. The conveyor belt 120 is installed on the top of the frame 110, and the negative pressure box 130 is built into the conveyor belt 120. A plurality of first holes 121 are opened on the conveyor belt 120, and a plurality of second holes 131 are opened on the top of the negative pressure box 130. The output end of the negative pressure member 140 and the negative pressure box 130 are used to form negative pressure at the first hole 121 above the second hole 131.

[0023] like Figure 7 As shown, the frame 110 includes a main frame 111 arranged in parallel, multiple longitudinal support frames 112, multiple transverse support frames 113, and multiple angle brackets 114. The bottom of the main frame 111 is connected to the multiple longitudinal supports via multiple angle brackets 114. The multiple longitudinal supports are connected to each other via multiple transverse support frames 113. The longitudinal support frames 112 and the transverse support frames 113 are connected via angle brackets 114. The conveyor belt 120 and the negative pressure box 130 are both mounted on the main frame 111. The main frame 111 is formed with a negative pressure air guide port 115 that communicates with the negative pressure box 130. The frame 110 has a stable structure, and other forms of frames 110 can also be used, without limitation.

[0024] It is understood that the conveyor belt 120 is a structure that can be imagined by those skilled in the art. The conveyor belt 120 is provided to transport tobacco leaves M, causing them to flow sequentially through the humidifying assembly 300 and the flattening assembly 200. A negative pressure box 130 is disposed within the conveyor belt 120. The negative pressure box 130 has a negative pressure chamber. Under the action of the negative pressure member 140, a negative pressure is generated in the negative pressure chamber, and suction is generated at the second hole 131 toward the first hole 121 above it, firmly adsorbing the leaves above the conveyor belt 120.

[0025] In this embodiment, the first hole 121 is a circular hole, and the second hole 131 is a bar-shaped hole. It is understandable that the first hole 121 and the second hole 131 can also be implemented in other shapes, which is not limited to this.

[0026] The negative pressure conveying assembly 100 in this embodiment also includes a third driving member 122 for driving the conveyor belt 120 to move. The third driving member 122 includes a conveyor belt driven wheel, a conveyor belt driving wheel, a diamond bearing seat, a conveyor belt motor and a speed regulator. The conveyor belt driving wheel is installed and matched with the conveyor belt 120 and fixed at both ends by the diamond bearing seat. The conveyor belt motor is connected to the conveyor belt driving wheel. The speed regulator is connected to the conveyor belt motor to control the running speed of the conveyor belt 120. The conveyor belt driven wheel is installed and matched with the conveyor belt 120 to transport cigar tobacco leaves M.

[0027] To improve flattening efficiency, multiple first holes 121 are distributed on both sides of the conveyor belt 120. Two flexible flattening members 220 are provided, one above each of the multiple first holes 121. This allows two tobacco leaves M to be placed simultaneously on the conveyor belt 120, effectively improving production efficiency. Of course, more tobacco leaves can be placed, and the number of tobacco leaves M to be placed depends on the size of the device and should be determined based on actual conditions.

[0028] like Figure 8 As shown, the negative pressure member 140 in this embodiment includes a centrifugal fan 141, a ventilation duct 142, and a conversion box 143. The air inlet of the centrifugal fan 141 is connected to the conversion box 143 via the ventilation duct 142. The conversion box 143 is fixed to the frame 110 and has an air guide port 144 connected to the negative pressure air guide port 115. The centrifugal fan 141 generates a negative pressure at the first hole 121 of the conveyor belt 120.

[0029] The flattening component 200 in this embodiment includes a fixing part 210 and a flexible flattening part 220 which are arranged in sequence along the conveying direction of the adsorption conveying surface and movably connected to the negative pressure conveying component 100. The fixing part 210 can be moved to a position where the tobacco leaves M on the adsorption conveying surface are pressed to fix the tobacco leaves M. The flexible flattening part 220 can be moved to a position where it is close to the tobacco leaves M on the adsorption conveying surface and can be rotated along its axial direction to flexibly contact and flatten the tobacco leaves M.

[0030] The fixing member 210 is used to fix the tobacco leaves M so that when the flexible flattening member 220 flattens the tobacco leaves M, the tobacco leaves M are deflected, thereby affecting the flattening work.

[0031] like Figure 2-3As shown, in one embodiment, the fixing member 210 includes two first brackets 211, a pressure plate 212 and a first driving member 213. The two first brackets 211 are relatively arranged on both sides of the negative pressure conveying component 100, and the pressure plate 212 is arranged across the adsorption conveying surface. The two ends of the pressure plate 212 are respectively connected to the two first brackets 211 via the first driving member 213. The output end of the first driving member 213 is used to drive the pressure plate 212 to move in a direction close to or away from the adsorption conveying surface.

[0032] Among them, the first driving member 213 includes two springs 213a and two electromagnets 213b, the pressure plate 212 is an iron plate, and the tops of the two ends of the pressure plate 212 are respectively connected to the two first brackets 211 via two springs 213a, and the two electromagnets 213b are fixedly arranged on the negative pressure conveying component 100, and the two electromagnets 213b are respectively arranged at the lower position of the two ends of the pressure plate 212. When the electromagnet 213b is energized, the electromagnet 213b attracts the pressure plate 212, and the pressure plate 212 moves downward until it is close to the adsorption conveying surface. When the electromagnet 213b is de-energized, the electromagnet 213b is separated from the pressure plate 212, and the pressure plate 212 moves upward until it is separated from the adsorption conveying surface.

[0033] Of course, in other embodiments, the first driving member 213 may also be implemented by a cylinder or other structure, and this is not limited.

[0034] like Figure 4 As shown, in one embodiment, the flexible flattening member 220 includes a second bracket 221, a second driving member 222 and an airbag 223. The second bracket 221 is fixedly connected to the negative pressure delivery component 100, and the second driving member 222 is installed on the second bracket 221. The output end of the second driving member 222 is connected to the airbag 223 to drive the airbag 223 to move in any direction and can drive the airbag 223 to rotate along its vertical axis.

[0035] In one embodiment, the second driving member 222 includes an X-axis screw module 222a, a Y-axis screw module 222b, a Z-axis screw module 222c and a digital servo 222d. The X-axis screw module 222a is installed on the second bracket 221, and the output end of the X-axis screw module 222a is connected to the Y-axis screw module 222b, for driving the Y-axis screw module 222b to move along the conveying direction parallel to the adsorption conveying surface. The output end of the Y-axis screw module 222b is connected to the Z-axis screw module 222c, for driving the Z-axis screw module 222c to move along the horizontal conveying direction perpendicular to the adsorption conveying surface. The output end of the Z-axis screw module 222c is connected to the digital servo 222d, for driving the digital servo 222d to move in the vertical direction. The output end of the digital servo 222d is connected to the airbag 223, for driving the airbag 223 to rotate along its vertical axis direction.

[0036] Among them, the output end of the digital servo 222d is connected to the airbag 223 via the coupling, the connecting pipe 330223a and the disc cover 223b in sequence. By inflating and deflating the airbag 223, the size of the airbag 223 and its elastic deformation can be controlled, thereby controlling the force applied to the tobacco leaf M.

[0037] It is understandable that the above-mentioned X-axis screw module 222a, Y-axis screw module 222b, Z-axis screw module 222c and digital servo 222d are structures that can be thought of by those skilled in the art, and no further elaboration and explanation will be given here.

[0038] The humidifying component 300 in this embodiment has a humidifying end disposed directly above the adsorption conveying surface, and the humidifying end is disposed between the fixing member 210 and the feed end of the negative pressure conveying component 100 .

[0039] like Figure 5 As shown, in one embodiment, the humidification assembly 300 includes a humidifier 310 and a spray pipe 320. The discharge end of the humidifier 310 is connected to one end of the spray pipe 320, and the other end of the spray pipe 320 is closed. The spray pipe 320 is arranged across the adsorption conveying surface. The bottom of the spray pipe 320 is provided with multiple spray holes 321 arranged at equal intervals along its length. The humidifier 310 and the spray pipe 320 can be connected by a connecting pipe 330223a. The shape of the connecting pipe 330223a depends on the actual installation location.

[0040] like Figure 9 As shown, the device in this embodiment also includes a flattening component 400 arranged between the flexible flattening member 220 and the discharge end of the negative pressure conveying component 100, and the flattening component 400 includes two flattening side plates 410 and two pressing rollers 420. The two flattening side plates 410 are relatively arranged on both sides of the negative pressure conveying component 100, and the two pressing rollers 420 span the adsorption conveying surface and are arranged in sequence along the conveying direction of the adsorption conveying surface. The two ends of the pressing roller 420 are respectively rotatably connected to the two flattening side plates 410, and the bottom of the pressing roller 420 is arranged in contact with the adsorption conveying surface.

[0041] It is understandable that the outer ring of the pressing roller 420 is made of rubber sponge material, which avoids damaging the tobacco leaves M during the process of flattening the tobacco leaves M.

[0042] On the other hand, an embodiment of the present invention further provides a method for using the adsorption-fixed cigar tobacco leaf M flattening device, which is applicable to the adsorption-fixed cigar tobacco leaf M flattening device described above, and further includes the following steps: Step 1: Place the tobacco leaves M to be flattened on the negative pressure conveying assembly 100. Under the action of negative pressure, the tobacco leaves M are adsorbed on the adsorption conveying surface; Step 2: The negative pressure conveying assembly 100 conveys the tobacco leaves M to a position below the humidifying end, and the humidifying end humidifies the tobacco leaves M; In step three, the negative pressure conveying component 100 conveys the tobacco leaves M to the position below the fixing part 210. The fixing part 210 presses the tobacco leaves M onto the adsorption conveying surface. The flexible flattening part 220 flexibly contacts the tobacco leaves M and flattens the tobacco leaves M by squeezing and rotating.

[0043] Compared with existing technologies: 1) This cigar tobacco leaf M parallel adsorption and conveying leaf spreading device has a rational structural design and is easy to use and operate. It can utilize fully mechanized and automated means to adsorb, convey, humidify, fix, flatten, and press the tobacco leaves M. This avoids the time-consuming process of operators repeatedly spreading the cigar tobacco leaves M by hand during current production, thereby improving efficiency and saving labor costs. 2) The present invention utilizes a conveyor belt 120 to transport tobacco leaves M, which can be used for assembly line operations and can simultaneously perform the spreading operation of two cigar tobacco leaves M in parallel, thereby realizing an automated process for spreading cigar tobacco leaves M, reducing the labor intensity of workers, and improving the production efficiency of spreading cigar tobacco leaves M. 3) The negative pressure conveying assembly 100 operates and transports the tobacco leaves M, allowing the tobacco leaves M adsorbed thereon to sequentially pass through the humidifying assembly 300, the flattening assembly 200, and the pressing assembly 400. The ventilation duct 142 does not need to move with it, does not need to stretch, does not deform, and does not affect the wind force, thereby ensuring that the cigar tobacco leaves M above it are always adsorbed. 4) The negative pressure adsorption force generated by the negative pressure conveying assembly 100 is used to adsorb the tobacco leaves M, thereby avoiding the need for other types of clamping members to clamp the tobacco leaves M, reducing damage to the tobacco leaves M, and providing a flat operating space for the flattening assembly 200 and the flattening assembly 400 without obstruction or interference from other components; 5) The fixing member 210 adopts an electromagnetic adsorption method. When working, the electromagnet 213b is energized, and the electromagnet 213b attracts and presses the pressing plate 212, so that it is fixed to the tail of the tobacco leaves M laid on the conveyor belt 120, thereby fixing the tobacco leaves M. After the operation is completed, the electromagnet 213b is de-energized, and the negative pressure conveying assembly 100 starts to move; 6) The rotary extrusion structure adopts the design of XYZ three-axis linear module, which can exert an all-round effect on the tobacco leaves M. At the same time, the digital servo 222d is used to rotate the tobacco leaves M. The airbag 223 is selected as the working part to flexibly contact the tobacco leaves M without damaging the tobacco leaves M. 7) The electric flattening assembly 200 and the flattening assembly 400 can be fixed to both sides of the frame 110 by bolts, which is easy to disassemble and assemble, and facilitates subsequent repair and maintenance; 8) A leaf spreading process of humidifying first and then fixing and flattening is proposed. The humidified tobacco leaves M have better flexibility and are more conducive to leaf spreading. The fixing and flattening of the tobacco leaves M can work simultaneously, which greatly improves the production efficiency of cigar tobacco leaves M and enhances the cigar tobacco leaves M spreading effect.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
