Description

Technical Field

[0002] In the tobacco processing technology, the main processing steps on the tobacco leaf-making line are generally as follows: slicing, loosening and rehydrating, moistening and adding ingredients, cutting into shreds, drying into shreds, and blending and flavoring. The finished tobacco is then transported to the packaging workshop. In this process, loosening and rehydrating is the first processing step at the beginning of the tobacco leaf-making line that affects the sensory quality of the final product. Its processing quality influences the stability of the process quality indicators in subsequent main processes such as moistening and adding ingredients, cutting into shreds, and drying into shreds. The task of the loosening and rehydrating process is to increase the moisture content and temperature of the tobacco leaves, improve their processing resistance, and ensure that the sliced ​​tobacco leaves are loose and free of clumping or agglomeration, thus improving the sensory quality of the tobacco.

The slicing effect can affect the effect of subsequent processing steps and ultimately affect the finished tobacco product. On the loosening and rehydration production line, tobacco sheets may pile up. Existing cutting equipment cannot handle the pile-up, which can cause jamming or even mechanical failure.

[0023] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0024] like Figure 1-5 As shown, a rotary blade cutting device is proposed according to a first aspect of the present application, comprising: a rotary blade assembly 100 for cutting and loosening tobacco sheets; a frame assembly 200, wherein the rotary blade assembly 100 is disposed on the frame assembly 200, the frame assembly 200 includes a lifting cylinder 210, and the lifting cylinder 210 is electrically connected to the rotary blade assembly 100; an air circuit system 300 connected to the lifting cylinder 210 for driving the lifting cylinder 210; and an electrical control system 400 electrically connected to the rotary blade assembly 100, the frame assembly 200, and the air circuit system 300, wherein the rotary blade assembly 100 achieves lifting function through the lifting cylinder 210, and the rotary blade assembly 100 has a first position and a second position, wherein the horizontal height of the second position is higher than that of the first position.

[0025] The rotary blade slicing device provided in this application embodiment includes a rotary blade assembly 100, a frame assembly 200, an air circuit system 300, and an electrical control system 400. The rotary blade assembly 100 is used to cut and loosen tobacco sheets. The rotary blade assembly 100 is connected to the frame assembly 200, which provides support for the rotary blade assembly 100 and secures and protects the entire device. The frame assembly 200 includes a lifting cylinder 210, to which the rotary blade assembly 100 is connected. The rotary blade assembly 100 switches between a first position and a second position via the lifting cylinder 210. The air circuit system 300 is connected to the lifting cylinder 210 and drives the lifting cylinder 210 to move up and down. The electrical control system is electrically connected to the frame assembly 200, the rotary blade assembly 100, and the air circuit system 300, and provides electrical power to the rotary blade slicing device.

[0026] In practical use, this rotary knife slicing device is used in tobacco pack slicing. The frame assembly 200 can adjust the height of the rotary knife assembly 100 through the lifting cylinder 210. This height is adjusted according to the height of the tobacco sheet fed into the rotary knife slicing device.

[0027] In this technical solution, the device is a further cutting and loosening process of tobacco sheets after the tobacco packs are sliced ​​in a tobacco processing production line, using a rotary cutter assembly 100. The tobacco sheets usually do not stack on the production line and their height remains relatively uniform. At this time, the rotary cutter assembly 100 is in the first position, further cutting the tobacco sheets. When the tobacco sheets stack, the rotary cutter assembly 100 can adjust its height to the second position to avoid the lower layer of tobacco sheets and cut the upper layer of tobacco sheets. This method can avoid material jamming when the tobacco sheets stack, improve the stability of the loosening and rehydration process, reduce the failure rate, and improve production efficiency.

[0028] like Figure 1-5 As shown, the frame assembly 200 includes: a main support 220, which includes a top plate, a front plate, a rear plate, and two side plates; the front plate has a feed inlet; the rear plate has a discharge outlet; the two side plates are respectively provided with lifting grooves 230, and the main support 220 is connected to the rotary cutter assembly 100 through the lifting grooves 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 grooves 230. The lifting end of the lifting cylinder can drive the rotary cutter assembly 100 to rise from a first position to a second position and / or fall from the second position to the first position in the side plate lifting grooves 230.

[0029] In this technical solution, the frame assembly 200 includes a main support 220, which includes a top plate, a front plate, a rear plate and two side plates. The front plate has a feed inlet, through which the sliced ​​cigarette packs enter the rotary blade cutting assembly. The rear plate has a discharge outlet, through which the material after being further cut and loosened by the rotary blade assembly 100 is discharged.

[0030] The main support 220 has two side plates with lifting slots 230 respectively. During installation, the two ends of the rotary cutter assembly 100 are embedded in the lifting slots 230 respectively, and the lifting function of the rotary cutter assembly 100 is realized by moving inside the lifting slots 230.

[0031] There are four lifting cylinders 210. Two lifting cylinders 210 are provided on each side plate, and the lifting cylinders 210 on the same side plate are respectively located on both sides of the lifting groove 230. During operation, the four lifting cylinders 210 need to ensure synchronous operation.

[0032] like Figure 1-5 As shown, the frame assembly 200 further includes: two incoming material detection sensors 240, which are respectively disposed on both sides of the feed inlet to detect whether material is entering the feed inlet; the photoelectric sensor is electrically connected to the rotary cutter assembly 100; and a stacking detection sensor 250, which is a through-beam photoelectric sensor used to detect the incoming material height; the stacking detection device is electrically connected to the rodless cylinder.

[0033] In this technical solution, the rack assembly 200 also includes an incoming material detection sensor 240 and a stacking detection sensor 250.

[0034] The incoming material detection sensor 240 is used to detect and determine whether material is arriving and is electrically connected to the rotary cutter assembly 100. When material is detected, the incoming material detection sensor 240 controls the rotary cutter assembly 100 to start cutting the material. There are two incoming material detection components. When one of them detects the incoming material signal, it controls the rotary cutter assembly 100 to rotate and cut. This setting increases the stability of incoming material recognition and avoids the situation where material arrives but is not recognized.

[0035] The material stacking detection sensor 250 is used to detect and determine the material height and is electrically connected to the lifting cylinder 210. Based on the material stacking height, the lifting cylinder 210 is controlled in real time to adjust the cutting height of the rotary blade assembly 100. This setting can automatically detect the material height and realize the automatic adjustment of the height of the rotary blade assembly 100, which increases the ease of use of the rotary blade cutting device.

[0036] like Figure 1-5As shown, the rack assembly 200 further includes: a magnetic detector, which is disposed on the lifting cylinder 210 and is used to detect whether the rotary blade assembly 100 has risen to the second position and / or fallen to the first position; and an alarm, which is electrically connected to the magnetic detector and the lifting cylinder 210. When the magnetic detector detects that the rotary blade assembly 100 has not risen to the specified position and / or the operating time of the lifting cylinder 210 exceeds a threshold, the alarm issues an alarm.

[0037] In this technical solution, the rack assembly 200 also includes a magnetic detector and an alarm.

[0038] It is understood that when the slicing ...

[0039] The magnetic detector is installed in the lifting cylinder 210 and is used to detect whether the rotary cutter assembly 100 has been raised or lowered to the correct position.

[0040] Specifically, the magnetic detector detects two heights: the highest point that the slicing ...

[0041] During normal operation, the rotary cutter assembly rises in approximately X seconds and descends in approximately Y seconds, where X > Y. If the time interval between rises exceeds X seconds, or the time interval between descents exceeds Y seconds, or if the rotary cutter magnetic detector detects that the rotary cutter assembly 100 is not in its proper position, an alarm will sound, reminding maintenance personnel to check the function of the lifting cylinder 210 or whether there is any jamming during the lifting process.

[0042] When the rotary cutter assembly 100 is in the second position for a period of time exceeding the threshold, it can be inferred that an abnormality such as frequent material accumulation has occurred on the production line. At this time, the alarm will sound to remind the staff to check and repair.

[0043] like Figure 1-5As shown, the rotary cutter assembly 100 includes: a rotary cutter shaft 110, both ends of which are connected to the frame assembly 200; a seated bearing 120 disposed at both ends of the rotary cutter shaft 110, and the rotary cutter shaft 110 connected to the frame assembly 200 via the seated bearings 120; multiple slicing rotary cutters 130, which are spaced apart from the rotary cutter shaft 110; and a reducer 140. The reducer 140 is disposed on the rotary cutter shaft 110 and is used to drive the slicing rotary cutter 130 to rotate. The cutting end of the slicing rotary cutter 130 is arc-shaped and includes a cutting side and a back side. 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 slicing rotary cutter 130 has two cutting sides and is centrally symmetrical. The center of symmetry of the slicing rotary cutter 130 overlaps with the axis of the rotary cutter shaft 110.

[0044] In this technical solution, the rotary cutter assembly 100 includes a rotary cutter shaft 110, a bearing 120 with a mounting seat, a slicing rotary cutter 130, and a reducer 140.

[0045] The rotary cutter shaft 110 is provided with bearings 120 at both ends. The rotary cutter shaft 110 is connected to the frame assembly 200 through the bearings 120. In this embodiment, the bearings 120 are connected to the lifting cylinder 210 and are located in the lifting groove 230 of the frame assembly 200. The slicing rotary cutters 130 are spaced apart on the rotary cutter shaft 110. The slicing rotary cutters 130 are used to cut the stacked tobacco sheets. The reducer 140 drives the slicing rotary cutters 130 to rotate and cut.

[0046] The cutting end of the slicing rotary cutter 130 is arc-shaped, and includes a cutting side and a back side. 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. In practical applications, the distance between the back side of the slicing rotary cutter 130 and the rotary cutter shaft 110 is relatively short. Therefore, the distance between the back side of the slicing rotary cutter 130 and the tobacco flakes traveling platform is sufficient for the tobacco flakes to pass through. The tobacco flakes can enter between the back side of the slicing rotary cutter 130 and the transport platform, ensuring that the tobacco flakes are cut evenly each time and further preventing material jamming.

[0047] like Figure 1-5 As shown, the rotary blade assembly 100 further includes an expansion sleeve structure 150, the number of which corresponds to the number of the slicing rotary blades 130. The slicing rotary blades 130 are connected to the rotary blade shaft 110 through the expansion sleeve structures 150, and the slicing rotary blades 130 are detachably connected to the expansion sleeve structures 150.

[0048] In this technical solution, the slicing rotary cutter 130 is connected to the rotary cutter shaft 110 through the expansion sleeve structure 150. The slicing rotary cutter 130 can be adjusted in position and angle through the expansion sleeve structure 150, which increases the ease of use and flexibility of this technical solution.

[0049] Meanwhile, the slicing rotary blade 130 is detachably connected to the expansion sleeve structure 150, so that the slicing rotary blade 130 can be easily installed and disassembled. When the blade becomes dull, it can be removed for grinding. In this embodiment, the expansion sleeve structure 150 and the slicing rotary blade 130 are connected by bolts.

[0050] like Figure 1-5 As shown, the rotary cutter assembly 100 further includes a frequency converter, which is electrically connected to the speed reducer 140.

[0051] In this technical solution, the rotary cutter assembly 100 also includes a frequency converter, which is electrically connected to the reducer 140. The frequency converter is used to adjust the rotational speed of the reducer 140 to match the speed of the front-mounted tobacco sheet conveyor belt motor, ensuring uniform loosening. Furthermore, according to production needs, the ratio of the reducer 140 speed to the front-mounted tobacco sheet conveyor belt motor speed can be manually set and adjusted to further optimize the loosening effect of the cut tobacco sheets.

[0052] 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 in the reducer 140 is overcurrent, the rotary cutter assembly 100 moves from a first position to a second position.

[0053] During use, when the cutting direction of the rotary cutter 130 is such that the tobacco flakes are loose and have gaps, the current passing through the reducer 140 is within the normal range. However, when the tobacco flakes on the conveyor belt are misaligned, preventing the rotary cutter 130 from cutting the tobacco flakes at the correct angle, the cutting resistance of the rotary cutter 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 cutter assembly 100 from the first position to the second position. This allows the tobacco flakes in abnormal positions to enter the subsequent structure through the rotary cutter, avoiding the accumulation of tobacco flakes caused by difficulty in cutting misaligned tobacco flakes, and further improving stability.

[0054] like Figure 1-5As shown, the air circuit system 300 includes: an air pump, which provides power for the movement of gas inside the air circuit components; an air source switch, which is manual and used to control the opening and closing of the air pump; an air pretreatment valve, which is located at the outlet end of the air pump and filters and regulates 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; and a five-way valve, which is specifically a pilot-operated, center-sealed, three-position five-way valve, which is connected to the speed control valve and the lifting cylinder 210.

[0055] 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. The speed control valve can adjust the lifting cylinder 210 by adjusting the air flow rate, thereby adjusting the lifting speed of the lifting cylinder 210. At the same time, the lifting speed of the four lifting cylinders 210 can be adjusted individually. Since the lifting speeds of different lifting cylinders 210 cannot be guaranteed to be exactly the same after they leave the factory, the speed control valve is adjusted to achieve complete synchronization of the four lifting cylinders 210 during the lifting process.

[0056] like Figure 1-5 As shown, the electrical control system 400 includes: an input / output port box; an input / output port module, the input / output port module being disposed inside the input / output port box and electrically connected to the rotary cutter assembly 100, the frame assembly 200, and the pneumatic system 300; and an emergency stop button, the emergency stop button being electrically connected to the input / output port module.

[0057] In this technical solution, the electrical control system 400 is used to drive, control, detect, alarm, and communicate the functional components of the device, enabling the rotary blade cutting device to complete the specified actions and communicate with the main line. The electrical control system 400 includes an input / output port box, input / output port modules, and an emergency stop button.

[0058] The input / output port box includes a main circuit breaker, a DC power supply, and a CPU-type programmable I / O adapter.

[0059] The electrical control system 400 is connected to the section control via a PN network.

[0060] The electrical control system 400 also includes an emergency stop button. When the rotary blade cutting assembly malfunctions, the power to the rotary blade cutting device can be cut off via the emergency stop button before maintenance can be carried out, thereby improving the safety of this technical solution.

[0061] Understandably, the electrical control system 400 also includes cables and wires.

[0062] like Figure 1-5 As shown, a loosening and rehumidifying machine is provided according to a second aspect of the embodiments of this application, comprising: a loosening and rehumidifying machine body; an inclined belt scale disposed on the loosening and rehumidifying machine body; a vibrating chute disposed on the loosening and rehumidifying machine body; and a rotary blade cutting device as described in any one of the above, wherein the end of the inclined belt scale is connected to the beginning of the vibrating chute, and the rotary blade cutting device is disposed at the connection between the inclined belt scale and the vibrating chute.

[0063] In this technical solution, the loosening and rehydration machine includes an inclined belt scale and a vibrating chute. It can be understood that the inclined belt scale serves as the upstream conveyor for the rotary blade cutting device. Furthermore, when the rotary blade assembly's rotation speed is adjustable, its speed should be coordinated with the conveying speed of the inclined belt scale to achieve a better slicing and loosening effect.

[0064] In 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 the device. Subsequently, the operator should manually test the rotary blade assembly 100, the lifting function of the rotary blade assembly 100, the material receiving detection device, and the material stacking detection device.

[0065] During the testing 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 raised to the correct position. If it is not raised to the correct position, it may be due to slow leakage of the lifting cylinder 210 causing the rotary blade assembly 100 to fall, or the slicing rotary blade 130 of the rotary blade assembly 100 not hovering at the specified angle when the device is stopped in an emergency. The device should be inspected.

[0066] Meanwhile, inspectors should check the pneumatic system, lifting air pump for jamming, and five-way valve for malfunctions. After confirming that there are no malfunctions, the five-way valve returns to the normally closed position, and the rotary blade cutting device enters standby mode.

[0067] When the incoming material detection sensor 240 detects a material signal and the stacking detection sensor does not detect that the height of the rotary cutter assembly 100 needs to be adjusted, 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 normally closed position, and the rotary cutter device enters the normal working state.

[0068] When the incoming material detection sensor 240 detects a material signal and the stacking 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 operates normally until the rotary cutter assembly 100 is raised or lowered to the correct position.
