In this process, loosening and rehydrating is the first processing step that affects the sensory quality of the process product at the beginning of the leaf silk line. Its processing quality will affect the stability of the process quality indicators of the subsequent main processes such as moistening and adding materials, cutting and shredding, and drying and shredding. The process task of the loosening and rehydrating process is to increase the moisture content and temperature of the tobacco leaves, improve the processing resistance of the tobacco leaves, make the tobacco leaves loose after slicing, and have no caking or clumping of the tobacco leaves, so that the sensory quality of the tobacco leaves is improved.

[0064] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0065] like Figure 1-5 As shown, according to the first aspect of an embodiment of the present application, a rotary blade cutting device is proposed, comprising: a rotary blade assembly 100, wherein the rotary blade assembly 100 is used to cut tobacco slices loosely; a frame assembly 200, wherein the rotary blade assembly 100 is arranged on the frame assembly 200, and the frame assembly 200 includes a lifting cylinder 210, and the lifting end of the lifting gas lever is electrically connected to the rotary blade assembly 100; an air circuit system 300, wherein the air circuit system 300 is connected to the air circuit system 300 connected to the lifting cylinder 210, and is used to drive the lifting cylinder 210; an electrical control system 400, wherein the electrical control system 400 is electrically connected to the rotary blade assembly 100, the frame assembly 200 and the air circuit system 300, wherein the rotary blade assembly 100 realizes a lifting function through the lifting cylinder 210, and the rotary blade assembly 100 has a first position and a second position, and the horizontal height of the second position is higher than that of the first position.

[0066] The rotary blade slicing device provided in the embodiment of the present application includes a rotary blade assembly 100, a frame assembly 200, an air circuit system 300 and an electrical control system 400; wherein the rotary blade assembly 100 is used to cut the tobacco slices loosely, and the rotary blade assembly 100 is connected to the frame assembly 200, and the frame assembly 200 is used to provide support for the rotary blade assembly 100 and fix and protect the entire device; at the same time, the frame assembly 200 includes a lifting cylinder 210, and the rotary blade assembly 100 is connected to the lifting cylinder 210, and the rotary blade assembly 100 is switched between a first position and a second position through the lifting cylinder 210; wherein the air circuit system 300 is connected to the lifting cylinder 210, and the air circuit system 300 is used to drive the lifting cylinder 210 to lift and lower; wherein the electrical control system is electrically connected to the frame assembly 200, the rotary blade assembly 100 and the air circuit system 300, and the electrical control system is used to provide electrical power for the rotary blade slicing device.

[0067] In actual use, the rotary blade slicing device is applied to cigarette pack slicing, and the frame assembly 200 can adjust the height of the rotary blade assembly 100 through the lifting cylinder 210, and the height is adjusted according to the height of the cigarette packs fed into the rotary blade slicing device.

[0068] In this technical solution, the device is a device for further slicing the tobacco slices into loose pieces through a rotary knife assembly 100 after the tobacco packs are sliced ​​in a tobacco silk production line. The tobacco slices are usually not stacked on the assembly line, and the height is basically kept uniform. At this time, the rotary knife assembly 100 is in a first position to further slice the tobacco slices. When the tobacco slices are stacked, the rotary knife assembly 100 can adjust the height to a second position to avoid the lower layer of tobacco slices and cut the upper layer of tobacco slices. This method can avoid material jamming when the tobacco slices are stacked, improve the stability of the loose rehumidification production process, reduce the failure rate, and improve production efficiency.

[0069] like Figure 1-5 As shown, the frame assembly 200 includes: a main body bracket 220, the main body bracket 220 includes a top plate, a front plate, a rear plate and two side plates; the front plate is provided with a feed port; the rear plate is provided with a discharge port; the two side plates are respectively provided with lifting slots 230, and the main body bracket 220 is connected to the rotary knife assembly 100 through the lifting slots 230; the lifting cylinders 210 are magnetically coupled rodless cylinders, and there are four of them. Two lifting cylinders 210 are respectively provided on the two side plates, and the two lifting cylinders 210 are respectively provided on both sides of the lifting slots 230. The lifting end of the lifting gas rod can drive the rotary knife assembly 100 to rise from the first position to the second position in the side plate lifting slots 230, and / or, to fall from the second position to the first position.

[0070] In this technical solution, the frame assembly 200 includes a main frame 220, which includes a top plate, a front plate, a rear plate and two side plates, wherein the front plate is provided with a feed port, through which the sliced ​​cigarette packs enter the rotary blade cutting assembly; the rear plate is provided with a discharge port, through which the loosened materials further cut by the rotary blade assembly 100 are discharged.

[0071] Among them, the two side panels of the main frame 220 are respectively provided with lifting grooves 230. During the installation process, the two ends of the rotary knife assembly 100 are respectively embedded in the lifting grooves 230, and the lifting function of the rotary knife assembly 100 is realized by moving inside the lifting grooves 230.

[0072] There are four lifting cylinders 210 , two of which are arranged on each side panel, and the lifting cylinders 210 arranged on the same side panel are arranged on both sides of the lifting slot 230 , respectively. During operation, the four lifting cylinders 210 must ensure synchronous movement.

[0073] like Figure 1-5As shown, the frame assembly 200 also includes: an incoming material detection sensor 240, the number of which is two, and the number of which is two, which are respectively arranged on both sides of the feed port, for detecting whether there is incoming material at the feed port, and the photoelectric sensor is electrically connected to the rotary cutter assembly 100; a pile detection sensor 250, the pile detection sensor 250 is a through-beam photoelectric sensor, for detecting the height of the incoming material, and the pile detection device is electrically connected to the rodless cylinder.

[0074] In this technical solution, the frame assembly 200 further includes an incoming material detection sensor 240 and a piled material detection sensor 250 .

[0075] Among them, the incoming material detection sensor 240 is used to detect and determine whether there is incoming material and is electrically connected to the rotary cutter assembly 100. When incoming material is detected, the incoming material detection sensor 240 controls the rotary cutter assembly 100 to start and cut the material. There are two incoming material detection assemblies. When one of them detects an incoming material signal, it controls the rotary cutter assembly 100 to rotate and cut. This setting increases the stability of incoming material identification and avoids the situation where incoming material is not identified.

[0076] Among them, the pile detection sensor 250 is used to detect and determine the material height, and is electrically connected to the lifting cylinder 210. According to the pile height of the incoming material, the lifting cylinder 210 is controlled in real time to adjust the cutting height of the rotary knife assembly 100. This setting can automatically detect the height of the incoming material and realize automatic adjustment of the height of the rotary knife assembly 100, thereby increasing the usability of the rotary knife cutting device.

[0077] like Figure 1-5 As shown, the frame assembly 200 also includes: a magnetic detector, which is arranged on the lifting cylinder 210 and is used to detect whether the rotary knife assembly 100 is lifted to the second position and / or lowered to the first position; an alarm, which is electrically connected to the magnetic detector and the lifting cylinder 210, and when the magnetic detector detects that the rotary knife assembly 100 is not lifted to the specified position, and / or the operating time of the lifting cylinder 210 exceeds a threshold, the alarm issues an alarm.

[0078] In this technical solution, the rack assembly 200 further includes a magnetic detector and an alarm.

[0079] It can be understood that when the slice cutting rotary cutter 130 of the rotary cutter assembly 100 stops rotating, the reducer 140 can keep the slice cutting rotary cutter 130 stopped at the same angle. In the present embodiment, when the slice cutting rotary cutter 130 stops, it always stops when one of the cutting sides of the slice cutting rotary cutter 130 is at the highest point, and at the same time, the other cutting side is at the lowest point.

[0080] The magnetic detector is disposed on the lifting cylinder 210, and is used to detect whether the rotary cutter assembly 100 is lifted into place.

[0081] Specifically, the magnetic detector detects two heights, namely, the highest point that the slicer blade 130 can reach when the rotary blade assembly 100 is in the second position, and the lowest point that the slicer blade 130 can reach when the rotary blade assembly 100 is in the first position.

[0082] In the normal operation of the device, the ascending process of the rotary cutter component is about X seconds, and the descending process is about Y seconds, X>Y. When the ascending process time interval exceeds X, or the descending process exceeds Y seconds, and the rotary cutter magnetic detector detects that the rotary cutter assembly 100 is not lifted or lowered into place, the alarm will sound an alarm to remind the maintenance personnel to check the function of the lifting cylinder 210 or whether there is a jamming phenomenon during the lifting process.

[0083] Among them, when the time when the rotary cutter assembly 100 is in the second position exceeds a threshold value, it can be inferred that the production line has abnormalities such as frequent material stacking. At this time, the alarm sounds an alarm to remind the staff to conduct inspections and repairs.

[0084] like Figure 1-5 As shown, the rotary cutter assembly 100 includes: a rotary cutter shaft 110, both ends of which are respectively connected to the frame assembly 200; a seat bearing 120, which is arranged at both ends of the rotary cutter shaft 110, and the rotary cutter shaft 110 is connected to the frame assembly 200 through the seat bearing 120; a slice cutter 130, the number of which is multiple, and the slice cutter 130 is arranged at intervals on the rotary cutter shaft 110; a reducer 140, The reducer 140 is arranged on the rotary cutter shaft 110, and is used to drive the slice cutting rotary cutter 130 to rotate; the cutting end of the slice cutting rotary cutter 130 is arc-shaped, and the cutting end of the slice cutting rotary cutter 130 includes a cutting side and a back side, and the distance from the cutting side to the center of the rotary cutter shaft 110 is greater than the distance from the back side to the center of the rotary cutter shaft 110; each of the slice cutting rotary cutters 130 has two cutting sides and is a centrally symmetrical structure, and the center of symmetry of the slice cutting rotary cutter 130 overlaps with the axis of the rotary cutter shaft 110.

[0085] In this technical solution, the rotary cutter assembly 100 includes a rotary cutter shaft 110 , a seat bearing 120 , a slice cutting rotary cutter 130 and a reducer 140 .

[0086] Among them, seat bearings 120 are respectively arranged at both ends of the rotary cutter shaft 110, and the rotary cutter shaft 110 is connected to the frame assembly 200 through the seat bearings 120. In this embodiment, the seat bearings 120 are connected to the lifting cylinder 210 and are arranged in the lifting groove 230 of the frame assembly 200. The slice cutting rotary cutter 130 is arranged at intervals on the rotary cutter shaft 110, and the cutting of the piled tobacco slices is achieved by the slice cutting rotary cutter 130. Among them, the reducer 140 drives the slice cutting rotary cutter 130 to rotate and cut.

[0087] The cutting end of the slice cutter 130 is arc-shaped, and the cutting end of the slice cutter 130 includes a cutting side and a back side, and the distance from the cutting side to the center of the slice cutter shaft 110 is greater than the distance from the back side to the center of the slice cutter shaft 110. In actual application, the back side of the slice cutter 130 is closer to the slice cutter shaft 110, so the distance between the back side of the slice cutter 130 and the sheet cigarette moving platform is sufficient for the sheet cigarette to pass through, and the sheet cigarette can enter between the back side of the slice cutter 130 and the transport platform, so that the slice cigarette is cut evenly each time, and further avoids the occurrence of material jamming.

[0088] like Figure 1-5 As shown, the rotary cutter assembly 100 further includes: an expansion sleeve structure 150 , the number of the expansion sleeve structures 150 corresponds to the slice cutter 130 , the slice cutter 130 is connected to the rotary cutter shaft 110 via the expansion sleeve structure 150 , and the slice cutter 130 is detachably connected to the expansion sleeve structure 150 .

[0089] In this technical solution, the slice cutting rotary cutter 130 is connected to the rotary cutter shaft 110 via the expansion sleeve structure 150. The position and angle of the slice cutting rotary cutter 130 are adjusted via the expansion sleeve structure 150, which increases the usability and flexibility of the technical solution.

[0090] At the same time, the slice cutting rotary cutter 130 is detachably connected to the expansion sleeve structure 150, so that the slice cutting rotary cutter 130 can be easily installed and disassembled, and the blade can be removed for grinding when it is not sharp. In this embodiment, the expansion sleeve structure 150 and the slice cutting rotary cutter 130 are connected by bolts.

[0091] like Figure 1-5 As shown, the rotary cutter assembly 100 further includes: a frequency converter, and the frequency converter is electrically connected to the reducer 140 .

[0092] In this technical solution, the rotary cutter assembly 100 also includes a frequency converter, which is electrically connected to the reducer 140 and is used to adjust the rotation speed of the reducer 140 to match the speed of the front tobacco conveyor belt motor to ensure loosening uniformity. According to production requirements, the ratio of the speed of the reducer 140 to the speed of the front tobacco conveyor belt motor can be manually set to further optimize the loosening effect of the cut tobacco.

[0093] like Figure 1-5 The rotary cutter assembly 100 further includes a current sensor, which is electrically connected to the reducer 140 and the frame assembly 200. When the current of the reducer 140 is over-current, the rotary cutter assembly 100 is transferred from the first position to the second position.

[0094] During use, the cutting direction of the slice cutting rotary knife 130 is such that the tobacco slices are loose and have gaps. At this time, the current passing through the reducer 140 is within the normal range. When the tobacco slices on the conveyor belt are out of position and the slice cutting rotary knife 130 cannot cut the tobacco slices at the correct angle, the cutting resistance of the slice cutting rotary knife 130 increases, and the current of the reducer 140 exceeds the normal range. At this time, the current sensor transmits an electrical signal to the frame assembly 200, changing the rotary knife assembly 100 from the first position to the second position, so that the tobacco slices in the abnormal position can enter the subsequent structure through the rotary knife cutting device, avoiding the difficulty in cutting the eccentric tobacco slices, resulting in the retention of tobacco slices and causing the pile of materials, thereby further improving the stability.

[0095] like Figure 1-5 As shown, the air circuit system 300 includes: an air pump, which is used to provide power for the movement of gas inside the air circuit component; an air source switch, which is manual and is used to control the opening and closing of the air pump; an air pretreatment valve, which is arranged at the air outlet end of the air pump to filter and regulate the pressure of the air pumped in by the air pump; a speed control valve, which is used to regulate the speed of the air pumped in by the air pump; a five-way valve, which is specifically a pilot-operated, center-sealed, three-position five-way valve, and the five-way valve is connected to the speed control valve and the lifting cylinder 210.

[0096] In this technical solution, the air circuit system 300 includes an air pump, an air source switch, an air pretreatment valve and a speed control valve, wherein the speed control valve can adjust the lifting cylinder 210 by adjusting the flow rate of the air, thereby adjusting the lifting speed of the lifting cylinder 210, and at the same time, the lifting speeds of the four lifting cylinders 210 can be adjusted separately. After different lifting cylinders 210 leave the scene, their lifting rates cannot be guaranteed to be exactly the same. Therefore, through the adjustment of the speed regulating valve, the four lifting cylinders 210 can be fully synchronized during the lifting process.

[0097] like Figure 1-5 As shown, the electrical control system 400 includes: an input / output port box; an input / output port module, which is arranged inside the input / output port box and is electrically connected to the rotary cutter assembly 100, the frame assembly 200 and the air circuit system 300; and an emergency stop button, which is electrically connected to the input / output port module.

[0098] In this technical solution, the electrical control system 400 is used to drive, control, detect, alarm, communicate and other functions of the functional components of the device, so that the rotary blade cutting device can complete the specified actions and communicate with the main line. The electrical control system 400 includes an input / output port box, an input / output port module and an emergency stop button.

[0099] Among them, the input / output port box includes a main circuit breaker, a DC power supply, and a CPU-type programmable I / O adapter configured in the box.

[0100] The electrical control system 400 is connected to the section control via a PN network.

[0101] Among them, the electrical control system 400 also includes an emergency stop button. When the rotary blade cutting component fails out of control, the emergency stop button can be used to cut off the power of the rotary blade cutting device and then repair it, thereby improving the safety of the present technical solution.

[0102] It can be understood that the electrical control system 400 also includes cables and wires.

[0103] like Figure 1-5 As shown, according to the second aspect of the embodiment of the present application, a loose rehumidification machine is proposed, comprising: a loose rehumidification machine body; a climbing belt scale, the climbing belt scale is arranged on the loose rehumidification machine body; a vibrating chute, the vibrating chute is arranged on the loose rehumidification machine body; a rotary blade cutting device as described in any one of the above, the end of the climbing belt scale is connected to the head end of the vibrating chute, and the rotary blade cutting device is arranged at the connection between the climbing belt scale and the vibrating chute.

[0104] In this technical solution, the loosening and rehumidifying machine includes a climbing belt scale and a vibrating chute. It can be understood that the climbing belt scale is the front transport line of the rotary blade cutting device, and when the rotary blade assembly 100 has an adjustable speed, its speed should be coordinated with the transport speed of the climbing belt scale, so as to achieve a better slicing loosening effect.

[0105] In the actual use of this embodiment, after the rotary blade cutting device is installed on the loosening and rehumidifying machine, the air source switch of the pneumatic system is manually turned on, and the electrical control system 400 is turned on to power on the device. Then, the operator should manually test the functions of the rotary blade assembly 100, the lifting function of the rotary blade assembly 100, the incoming material detection device, and the stacking material detection device.

[0106] During the inspection of the rotary blade cutting device, the rotary blade assembly 100 is set at the uppermost end of the lifting range. At this time, the magnetic switch is used to detect whether the rotary blade assembly 100 is lifted into place. If it is not lifted into place, the rotary blade assembly 100 may fall due to a slow leakage of the lifting cylinder 210, or the slicing rotary blade 130 of the rotary blade assembly 100 may not hover to the specified angle when the device is stopped in an emergency. The device should be inspected.

[0107] At the same time, the inspectors should check whether the pneumatic system, the lifting air pump are stuck and whether the five-way valve is faulty. After confirming that there is no fault, the five-way valve returns to the middle normally closed position and the rotary blade cutting device enters the standby state.

[0108] When the incoming material detection sensor 240 detects a material signal and the stacking detection sensor does not detect the need to adjust the height of the rotary cutter assembly 100, the reducer 140 of the rotary cutter assembly 100 drives the slicing rotary cutter 130 of the rotary cutter assembly 100 to rotate, the five-way valve remains in the middle normally closed position, and the rotary cutter device enters a normal working state.

[0109] When the incoming material detection sensor 240 detects a material signal and the stacking material detection sensor detects that the height of the rotary cutter assembly 100 needs to be adjusted, the five-way valve opens and the height of the rotary cutter assembly 100 is adjusted by the lifting cylinder 210. At the same time, the rotary cutter assembly 100 works normally until it is lifted and lowered into place.
