The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0032] like Figures 1 to 8As shown, the tobacco powder roller-pressing forming equipment of the first embodiment includes: a frame assembly 10, a pressure roller assembly 20 and a detection assembly 30. The pressure roller assembly 20 includes a first dynamic pressure roller structure 21, a second dynamic pressure roller structure 22, a fixed pressure roller structure 23 and a third dynamic pressure roller structure 24. The first dynamic pressure roller structure 21, the second dynamic pressure roller structure 22 and the third dynamic pressure roller structure 24 are all movably arranged on the frame assembly 10, and the fixed pressure roller structure 23 is arranged on the frame assembly 10. A pre-forming area is formed between the first dynamic pressure roller structure 21 and the second dynamic pressure roller structure 22, a first forming area is formed between the second dynamic pressure roller structure 22 and the fixed pressure roller structure 23, and a second forming area is formed between the fixed pressure roller structure 23 and the third dynamic pressure roller structure 24. The detection assembly 30 is arranged on the frame assembly 10 and corresponds to the pressure roller assembly 20, so as to adjust the gaps between the pre-forming area, the first forming area and the second forming area respectively according to the detection results of the detection assembly 30.

[0033] By applying the technical solution of this embodiment, the parameters to be detected are detected by the detection component 30 arranged on the frame component 10, which greatly reduces the parameters that need to be detected manually. The pressure roller component 20 is adjusted according to the detection result of the detection component 30, thus avoiding the problem of much hysteresis in manual detection. The technical solution of this embodiment effectively solves the hysteresis of manual detection and manual adjustment in the prior art, as well as the time-consuming and labor-intensive problems.

[0034] like Figures 1 to 8As shown, in the technical solution of this embodiment, the first dynamic pressure roller structure 21 includes a first moving driving unit 211, a first rotating driving unit 212, a first dynamic pressure roller 213 and a first pressure roller seat 214. The first moving driving unit 211 is arranged on the frame assembly 10, the first pressure roller seat 214 can be arranged on the frame assembly 10 in a translational manner, the first rotating driving unit 212 is connected to the first pressure roller seat 214, the first dynamic pressure roller 213 is rotatably arranged on the first pressure roller seat 214, and the first rotating driving unit 212 is connected to the first dynamic pressure roller 213. The first moving driving unit 211 can drive the first dynamic pressure roller 213 to approach or move away from the second dynamic pressure roller structure 22 to adjust the size of the preforming area, so that the preforming of the tobacco powder can better meet the requirements. It should be noted that the first moving driving unit 211 includes a first moving motor and a first screw, and the first pressure roller seat 214 has a threaded hole adapted to the first screw. The bottom surface of the first pressure roller seat 214 has a dovetail groove, and the frame assembly 10 is provided with a convex rail adapted to the dovetail groove, so that the horizontal movement can be realized while the other directions are limited. In this way, the rotation of the first moving motor is converted into the rotation of the first screw, and the rotation of the first screw is converted into the translation of the first pressure roller seat 214. The above structure has a high degree of automation, high adjustment efficiency, and relatively accurate adjustment. The first dynamic pressure roller 213 and the second dynamic pressure roller are on approximately the same horizontal plane, and the dovetail groove of the first pressure roller seat 214 is arranged horizontally. There are two first moving motors, two first screws, and two first pressure roller seats 214. The two ends of the first dynamic pressure roller 213 are respectively matched with the two first pressure roller seats 214 in rotation, and a first moving motor, a first screw, and a first pressure roller seat 214 are arranged correspondingly. The transmission of the above structure is more stable and the force is more balanced. As another practicable method, the first moving drive unit 211 may include a cylinder or a hydraulic cylinder, and there is no need to set a transmission structure such as a screw.

[0035] like Figure 2 and Figure 3As shown, in the technical solution of this embodiment, the second dynamic pressure roller structure 22 includes a second movable driving unit, a second dynamic pressure roller and a second pressure roller seat, the second movable driving unit is arranged on the frame assembly 10, the second pressure roller seat is movably arranged on the frame assembly 10, the second dynamic pressure roller is rotatably arranged on the second dynamic pressure roller seat, and the second movable driving unit is connected to the second pressure roller seat. The above structure has high adjustment efficiency and easy control of adjustment accuracy. A preforming area is formed between the first dynamic pressure roller and the second dynamic pressure roller. The second movable driving unit drives the second pressure roller seat to move vertically, the dovetail groove of the second pressure roller seat is arranged vertically, and the slide rail on the frame assembly 10 that matches the second pressure roller seat is arranged vertically. The second movable driving unit includes a second mobile motor and a second screw rod, the second pressure roller seat has a threaded hole that matches the second screw rod, the second screw rod is connected to the rotating shaft of the second mobile motor, and the second mobile motor converts the second pressure roller seat into up and down movement by driving the rotation of the second screw rod. It should be noted that the second movable motor is directly connected to the second screw rod, or the second movable motor is connected to the second screw rod through a bevel gear: the first bevel gear is arranged on the second movable motor, the second bevel gear is installed on the end of the second screw rod away from the second pressure roller seat, the rotating shaft of the second movable motor is arranged horizontally, and the second screw rod is arranged vertically. Such a structure further improves the versatility and makes the structure more compact.

[0036] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the fixed pressure roller structure 23 includes a second rotary drive motor 231 and a fixed pressure roller 232, the second rotary drive motor 231 is arranged on the frame assembly 10, the fixed pressure roller 232 is rotatably mounted on the frame assembly 10, and the fixed pressure roller 232 is arranged vertically corresponding to the second dynamic pressure roller. The arrangement of the fixed pressure roller structure 23 can not only meet the requirements of adjusting the first molding area and the second molding area, but also meet the requirements of reducing the dynamic equipment structure. Such a structure has lower processing costs and is easier to maintain. It should be noted that the fixed pressure roller 232 is arranged vertically corresponding to the second dynamic pressure roller, which means that the rotating shaft of the fixed pressure roller 232 and the rotating shaft of the second dynamic pressure roller are in the vertical plane.

[0037] like Figure 3As shown, in the technical solution of this embodiment, the fixed pressure roller structure 23 also includes a first gear 233, and the second dynamic pressure roller structure 22 includes a second gear 221. The first gear 233 is connected to the fixed pressure roller 232, and the second gear 221 is connected to the second dynamic pressure roller, and the first gear 233 and the second gear 221 are meshed. The transmission between the first gear 233 and the second gear 221 is more stable. In the technical solution of this embodiment, the first gear 233 and the second gear 221 can be directly meshed, or can be transmitted through other transmission gears, for example, the first gear 233 and the second gear 221 are transmitted through one or more transmission gears. It should be noted that the fixed pressure roller 232 and the second dynamic pressure roller have a certain speed difference, so that the tobacco powder can easily separate from the fixed pressure roller 232 and the second dynamic pressure roller after being pressed. According to the use environment, in the technical solution of this embodiment, when the second dynamic pressure roller moves up and down, the adjustment amount is relatively small (for example, the adjustment amount can be 1mm), and such an adjustment amount ensures that the first gear and the second gear are in a matched state.

[0038] like Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the third dynamic pressure roller structure 24 includes a third movable driving unit, a third dynamic pressure roller and a third pressure roller seat. The third pressure roller seat is movably arranged on the frame assembly 10, and the third dynamic pressure roller is rotatably mounted on the third pressure roller seat. The third movable driving unit is arranged on the frame assembly 10, and the third movable pressure roller is connected to the third pressure roller seat. The third dynamic pressure roller is located on the side of the fixed pressure roller 232 away from the second dynamic pressure roller. The above structure makes it easy for the third dynamic pressure roller structure 24 to adjust the size of the second molding area, that is, the gap between the third dynamic pressure roller and the fixed pressure roller 232. The above structure has a high degree of automation. It should be noted that the third movable driving unit includes a third movable motor and a third screw, and its structure is similar to that of the second movable driving unit and the first movable driving unit, except that the position is adjusted accordingly, which will not be repeated here.

[0039] like Figure 3 As shown, in the technical solution of this embodiment, the detection component 30 includes a mobile detection module 31, and the mobile detection module 31 is arranged corresponding to the first dynamic pressure roller structure 21, the second dynamic pressure roller structure 22 and the third dynamic pressure roller structure 24. The arrangement of the mobile detection module 31 facilitates the real-time acquisition of the distances moved by the first dynamic pressure roller, the second dynamic pressure roller and the third dynamic pressure roller, so that the adjustment accuracy is higher. The mobile detection module 31 of this embodiment includes a displacement sensor, for example, a transmitter is arranged on the rotating shaft, and a receiver is arranged on the fixed seat. The transmitter and the receiver are docked once every time the rotating shaft rotates one circle. The distance pushed each time is certain. The processor can calculate the moving distance through the number of rotations. The first moving motor, the second moving motor and the third moving motor are all forward and reverse motors, so that the distance can be reduced or increased at any time.

[0040] like Figure 7 As shown, in the technical solution of this embodiment, the detection component 30 also includes a thickness detection module 32, which is arranged on the frame component 10 and is arranged opposite to the pressure roller component 20; and the detection component 30 also includes a width detection module 33, which is arranged on the frame component 10 and is arranged corresponding to the pressure roller component 20. The above structure can detect the thickness, width and other parameters of the pressed tobacco powder. The detection component 30 also includes a pressure detection module, which includes a plurality of pressure sensors, each of which measures the pressure of the pressure roller. For example, a pressure sensor is arranged between the first dynamic pressure roller and the first pressure roller seat (arranged at the horizontal force between the first dynamic pressure roller and the first pressure roller seat), and the extruded thickness of the tobacco powder can be judged according to the detected pressure. The same principle applies to the second dynamic pressure roller and the fixed pressure roller, and the fixed pressure roller and the third dynamic pressure roller.

[0041] It should be noted that, as another embodiment, the thickness detection module 32 and the width detection module 33 may be provided separately. For example, the second embodiment only provides the thickness detection module 32, and the third embodiment only provides the width detection module 33.

[0042] In the technical solution of this embodiment, the tobacco powder roller-pressing forming equipment further includes a control component, which is electrically connected to the detection component 30 and the pressure roller component 20. The tobacco powder roller-pressing forming equipment of the above structure has a high degree of automation. The control component includes a memory, a processor, etc. The parameters of the tobacco powder to be extruded, such as thickness, are input into the memory, and the processor adjusts the pre-forming area, the first forming area, and the second forming area according to the input parameters and the data actually measured by the detection component 30.

[0043] like Fig. 9 As shown, the present application also provides an adaptive flexible continuous forming process, which adopts the above-mentioned cigarette powder roller forming equipment, and the adaptive flexible continuous forming process includes the following steps: determining the detection parameters of the detection component 30. The detection component 30 detects the detection parameters, and when the detection parameters detected by the detection component 30 are outside the set detection parameter range, the pressure roller component 20 is adjusted. The adaptive flexible continuous forming process of the present application has high adjustment efficiency, good adjustment accuracy, and rapid response.

[0044] Step 1: Divide the pressing and forming process of the tobacco powder into a feed forming area (preforming area) and two thickness forming areas (first forming area and second forming area). Figure 7 As shown, the initial parameters of pressure and gap in each zone are determined according to the parameters required for the final forming of the smoke powder.

[0045] Step 2: At the strip pressure roller in the last thickness forming zone, two groups of laser distance measuring sensors are arranged in parallel: a thickness sensor group (thickness detection module 32) and a width sensor group (width detection module 33). Figure 7 As shown in the figure, the thickness sensor group is located at the left and right center of the roller surface to ensure that the layer thickness data of the tobacco powder pressed into the film can be collected. The width sensor group is located at the edges of both sides of the roller surface to detect whether the width of the tobacco powder film exceeds the requirement. By measuring the distance between the coating roller and the sensor, the instantaneous detection value of the roller position in multiple forming areas is obtained. The processing module is used to filter the instantaneous value to obtain the initial detection value of the coating roller.

[0046] Step 3: Add wet tobacco powder for pressing. The wet tobacco powder is pressed into a film by a pressing roller. The distance between the pressing roller covering the tobacco powder film and the thickness detection sensor group is measured. After filtering by the processing module, the actual distance change value ΔZ between the pressing roller and the sensor (i.e., the real-time thickness of the tobacco powder film) is calculated.

[0047] Step 4: if the real-time thickness detection value of the smoke powder film is greater than or less than the set value, reduce or increase the pressure in the forming zone until the actual thickness detection value of the smoke powder film meets the set value.

[0048] Step 5: Measure the distance between the pressure roller covering the smoke powder film and the width sensor group. When the measured value is less than the initial detection value, it means that the width of the smoke powder film has exceeded the set value. Then, slightly adjust the pressure roller gap in the feeding area until the width of the smoke powder film meets the requirements.

[0049] It should be noted that in the embodiment of the present application, there is a speed difference between the first dynamic roller structure and the second dynamic roller structure, the second dynamic roller structure and the fixed roller structure, and the fixed roller structure and the third dynamic roller structure, so that the detachment of the smoke powder film can be well ensured. When the speed difference is large, the smoke powder film will be damaged. When the speed difference is small, the effect of the detachment of the smoke powder film is not good, and the phenomenon of the smoke powder film not detaching is likely to occur. The embodiment of the present application adopts: the diameters of the above-mentioned rollers are the same, so the processing cost is low and the maintenance is convenient. The ratio of the rotation speed of the first dynamic roller 213 of the first dynamic roller structure 21 to the rotation speed of the second dynamic roller of the second dynamic roller structure 22 is between 1:1.15 and 1:1.4, the ratio of the rotation speed of the second dynamic roller of the second dynamic roller structure 22 to the rotation speed of the fixed roller of the fixed roller structure is between 1:1.15 and 1:1.4, and the ratio of the rotation speed of the fixed roller to the rotation speed of the third dynamic roller is between 1:1.15 and 1:1.4. Some of the embodiments adopt the ratios as follows: the speed ratio of the first dynamic roller 213 of the first dynamic roller structure 21 to the speed ratio of the second dynamic roller of the second dynamic roller structure 22 is between 1:1.32, the speed ratio of the second dynamic roller of the second dynamic roller structure 22 to the speed ratio of the fixed roller of the fixed roller structure is between 1:1.28, and the speed ratio of the fixed roller to the speed ratio of the third dynamic roller is 1:1.19. The above speed ratios take into account the thickness of the smoke powder film at each stage, the force it bears, and the peeling effect.
