[0043] like Figure 1 As shown, the present invention provides a forming system for reconstituted tobacco production, which is mainly suitable for thick pulp method reconstituted tobacco production.

[0044] The forming system for producing reconstituted tobacco leaves comprises a headbox 100, a feeding module, a voltage stabilizing module, and a liquid level regulating module;

[0045] The headbox 100 is provided with a discharge port, which is located on the lower side wall of the headbox 100. The thick slurry in the headbox 100 can be discharged through the discharge port, and the thick slurry can be coated on the corresponding conveyor belt after being discharged from the discharge port.

[0046] Optionally, the headbox 100 is composed of a box body and an upper cover, and the upper cover is arranged on the upper opening of the box body to facilitate opening and closing and cleaning of the headbox 100.

[0047] The feeding module includes a feeding pump 210, and the feeding pump 210 is connected to the feed port 110 near the bottom of the slurry box 100 through a pipeline. The feeding pump 210 can pump thick slurry for the slurry box 100, wherein the feed port 110 is arranged near the bottom of the slurry box 100, so that the thick slurry transported by the feeding pump 210 can be effectively reduced from splashing after entering the interior of the slurry box 100 through the feed port 110, thereby preventing the thick slurry from condensing into lumps on the inner wall of the slurry box 100.

[0048] The pressure stabilizing module includes a pressure stabilizing tank 330, the output end of the pressure stabilizing tank 330 is connected to the air inlet 120 near the top of the headbox 100 through a pipeline, and the input end of the pressure stabilizing tank 330 is connected to the input pipeline of compressed gas. The pressure stabilizing tank 330 can provide compressed air with stable pressure in the headbox 100; when the speed of the compressed air delivered by the input pipeline of compressed air is too fast, the pressure stabilizing tank 330 will cut it off to maintain the stable air pressure in the headbox 100.

[0049] The liquid level adjustment module is installed on the headbox 100 to adjust the height of the thick stock liquid level in the headbox 100 .

[0050] In some embodiments of the present invention, the feeding module further includes a flow meter 220 , which is disposed on a pipeline between the feeding pump 210 and the headbox 100 to measure the flow rate of the thick slurry delivered by the feeding pump 210 .

[0051] Furthermore, an adjusting component 230 is provided between the flow meter 220 and the feeding pump 210 for adjusting the flow rate of the thick slurry delivered by the feeding pump 210; specifically, the flow meter 220 can measure the flow rate of the thick slurry delivered by the feeding pump 210 to the headbox 100 in real time, and transmit the metering data to the adjusting component 230, thereby driving the adjusting component 230 to adjust the delivery efficiency of the feeding pump 210 according to a preset threshold value; that is, the feeding pump 210 is feedback-controlled by the flow meter 220, the operator sets the control threshold of the slurry flow in the adjusting component 230, the flow meter 220 detects the flow and feeds back the signal to the adjusting component 230, and the adjusting component 230 automatically adjusts the feeding pump 210 to stabilize the flow. When the thick slurry concentration is constant (controlled by the front-end preparation link), the thick slurry liquid level height in the headbox 100 is constant (controlled by the liquid level adjustment module provided in this embodiment), and the running speed and width of the conveyor belt remain unchanged, the feeding flow of the feeding module can be changed by changing the preset value of the adjustment component 230 to achieve rapid adjustment of the finished product quantity; in other words, the specific relationship between the aforementioned finished product quantity and the feeding flow is: feeding flow×thick slurry concentration×thick slurry density=running speed×width×finished product quantity, so a stable flow can ensure a stable finished product quantity, and at the same time, the finished product quantity can be quickly adjusted through flow changes.

[0052] In some embodiments of the present invention, the pressure stabilizing module also includes a filter pressure reducing valve 320; the input end of the filter pressure reducing valve 320 is connected to the input pipeline of the compressed gas; the output end of the filter pressure reducing valve 320 is connected to the input end of the pressure stabilizing tank 330 through a pipeline, further improving the regulating effect of the gas flow rate and ensuring the smooth output of pressure.

[0053] Furthermore, a manual valve 310 is provided on the compressed gas input pipeline to facilitate the manual control of the compressed gas input by the staff, thereby improving safety.

[0054] In some embodiments of the present invention, the liquid level regulating module includes a liquid level sensor 410 , an air pressure sensor 420 , a total pressure sensor 430 , a proportional valve 440 , and a control component 450 .

[0055] Specifically, the liquid level sensor 410 is installed at the upper end of the headbox 100 to measure the height of the thick slurry level in the headbox 100; the air pressure sensor 420 is installed on the upper side of the headbox 100 to measure the air pressure inside the headbox 100; the total pressure sensor 430 is installed on the lower bottom side of the headbox 100 to measure the total pressure of the thick slurry inside the headbox 100; the proportional valve 440 is installed on the pipeline between the pressure stabilizing tank 330 and the headbox 100.

[0056] Furthermore, the control component 450 is electrically connected to the proportional valve 440, the liquid level sensor 410, the total pressure sensor 430 and the air pressure sensor 420, respectively. The control component 450 can regulate the pressure of the compressed air in the headbox 100 through the proportional valve 440 to keep the liquid level of the thick slurry in the headbox 100 constant; that is, the data measured in real time by the liquid level sensor 410, the air pressure sensor 420 and the total pressure sensor 430 are directly transmitted to the control component 450, and then the proportional valve 440 is regulated by the control component 450, and finally the pressure in the headbox 100 is adjusted to keep the liquid level of the thick slurry in the headbox 100 constant, so as to ensure the normal operation of the headbox 100.

[0057] The forming system for producing reconstituted tobacco leaves provided by the present invention, when in use, uses the feeding module feeding pump 210 to convey the thick slurry to the headbox 100 through the feed port 110, and uses the flow meter 220 to measure the flow rate of the thick slurry conveyed by the feeding pump 210 in real time and transmit it to the regulating component 230, and uses the regulating component 230 to regulate the feeding pump 210 to ensure that the flow rate is stable when the thick slurry is conveyed; then, compressed air is conveyed to the headbox 100 through the pressure stabilizing module, and the pressure of the conveyed compressed air is stabilized by the pressure stabilizing tank 330, so as to ensure that when the concentration and viscosity of the thick slurry in the headbox 100 are both high, it can still be stably pressed out from the discharge port by the air pressure in the headbox 100 and coated on the corresponding on the conveyor belt; the relevant data in the headbox 100 is also monitored in real time through the liquid level sensor 410, the air pressure sensor 420, and the total pressure sensor 430 and transmitted to the control component 450. When the air pressure value and the pressure value in the headbox 100 exceed the preset threshold value of the control component 450, the proportional valve 440 is adjusted by the control component 450 to reduce the rate of conveying compressed air into the headbox 100. When the thick slurry liquid level in the headbox 100 is too high and exceeds the preset threshold value of the control component 450, the conveying power of the feeding pump 210 is adjusted by the control component 450 to reduce, and finally the liquid level of the thick slurry in the headbox 100 is kept constant to ensure the normal operation of the headbox 100.

[0058] like Figures 2 to 3 As shown, the present invention also provides equipment for a forming system for reconstituted tobacco production, including a flow box 100 and a knife door 500; the flow box 100 has a closed cavity inside, a side wall of the flow box 100 is provided with a feed inlet 110 near the bottom, and a side wall of the flow box 100 is provided with an air inlet 120 near the top; the knife door 500 is installed on the side wall of the flow box 100 near the bottom and is docked with the discharge port provided on the flow box 100, and the thick slurry in the flow box 100 can be discharged through the knife door 500.

[0059] Furthermore, a detection port 150 is provided at a side edge of the bottom end of the headbox 100 , and a total pressure sensor 430 is connected to the detection port 150 .

[0060] Furthermore, a plurality of feed ports 110 are evenly distributed in the horizontal direction to improve the uniformity of the thick slurry when it is transported into the headbox 100 .

[0061] Furthermore, the knife door 500 is provided with an opening adjustment device for adjusting the opening size of the knife door 500, so as to adjust the coating speed and thickness of the headbox 100 according to demand.

[0062] like Figure 4 , Figure 5 As shown, in some embodiments of the present invention, the knife door 500 includes an upper lip plate 510 and a lower lip plate 520, and the upper lip plate 510, the lower lip plate 520 and the corresponding side plates form a material transfer channel, wherein the upper lip plate 510 and the lower lip plate 520 are both slender plates, and the two ends of the upper lip plate 510 and the lower lip plate 520 are respectively connected by corresponding side plates; the material transfer channel is installed on the headbox 100 through a connecting plate 530. The opening adjustment device is installed at the end of the material transfer channel away from the headbox 100.

[0063] Further, a distance between ends of the upper lip plate 510 and the lower lip plate 520 close to the headbox 100 is greater than a distance between ends of the upper lip plate 510 and the lower lip plate 520 far from the headbox 100 .

[0064] In some embodiments of the present invention, the opening adjustment device includes a blocking plate 540 and a threaded rod 550; the blocking plate 540 is arranged at the opening of the feed channel away from the slurry box 100; the threaded rod 550 is threadedly inserted into the upper lip plate 510, and the lower end of the threaded rod 550 is rotatably connected to the blocking plate 540; rotating the threaded rod 550 can adjust the relative position of the blocking plate 540 and the knife door 500; in other embodiments, an electric control rod or a pneumatic turbine can also be used to adjust the position of the blocking plate 540.

[0065] Furthermore, a plurality of the threaded rods 550 are evenly distributed to ensure the stability of the position of the blocking plate 540; the plurality of threaded rods 550 are linked together by a linkage mechanism, and each threaded rod 550 can be driven to rotate synchronously by manipulating the linkage mechanism; in other embodiments, the linkage mechanism is electrically driven.

[0066] In some embodiments of the present invention, a viewing mirror 130 is provided on the side wall of the headbox 100 , so that the staff can directly observe the height of the thick slurry level in the headbox 100 .

[0069] Furthermore, the homogenizing roller 140 is a mirror roller with holes. The hole setting of the homogenizing roller 140 can effectively improve its stirring effect. The mirror setting on the outside of the homogenizing roller 140 can effectively reduce the adhesion and agglomeration of thick slurry on the outer surface of the homogenizing roller 140, avoiding blockage of the knife door 500.

[0070] Specifically, when the homogenizing roller 140 is rotating, the thick slurry level in the headbox 100 is higher than the upper surface of the homogenizing roller 140 , which can effectively prevent the homogenizing roller 140 from bringing bubbles into the thick slurry when rotating.

[0071] Furthermore, two homogenizing rollers 140 are symmetrically provided, and the rotation directions of the two homogenizing rollers 140 are opposite, so that the flow effect of the thick pulp in the headbox 100 can be better.

[0072] The equipment of the forming system for reconstituted tobacco leaf production provided by the present invention, when in use, by inputting thick slurry from the feed port 110 and then introducing compressed air through the air inlet 120, the air pressure in the headbox 100 can squeeze the thick slurry to be discharged from the knife door 500 and coated on the corresponding conveyor belt, and when coating the thick slurry with high concentration and viscosity, by increasing the rate of introducing compressed air, that is, increasing the air pressure in the headbox 100, the thick slurry can be smoothly discharged from the knife door 500; and when the thick slurry liquid level in the headbox 100 is higher than the upper surface of the homogenizing roller 140, the homogenizing roller 140 can be started to rotate and stir the thick slurry, so that the thick slurry in the headbox 100 keeps flowing and avoids the thick slurry in the upper layer from agglomerating; and the opening adjustment device arranged on the knife door 500 allows the staff to directly adjust the opening size of the knife door 500 without stopping the headbox 100, which can greatly improve the production efficiency.
