Guide rails 121 are provided on the outer sides of the first baffles 12 on both sides of the sliding slot. A slide 131 cooperates with the guide rail 121 via a slider 132 and is driven up and down by the telescopic cutting rod 14. The slide 131 is connected to the lower end of the telescopic cutting rod 14 driven by a power (pneumatic or hydraulic) on the crossbeam 16 at the top of the baffle. The two ends of the cutter 13 are hinged to the slide 131 via corresponding rods.
[0038] The clamping structure 15 includes a bracket 151 arranged between the tops of the first baffles 12, a clamping telescopic rod 152 driven by power (pneumatic or hydraulic) arranged on the bracket, a clamping follower rod 154 located on the outside of the telescopic rod, and a pressing member 153 connected to the lower end of the clamping telescopic rod.
[0039] In the present invention, a sensor for detecting whether tobacco leaves pass through is provided on the first conveyor belt 11 located below the cutter.
[0040] There are at least two compression telescopic rods 152, and the pressing member 153 includes a synchronization rod 1531, a connecting member 1532 and two pressure plates 1533. The synchronization rod 1531 is connected to the lower ends of the compression telescopic rod 152 and the compression follower rod 154. The compression follower rod 154 is installed in the bracket 5 and moves up and down with the compression telescopic rod. The lower end of the pressure plate 1533 is provided with a plurality of convex teeth; guide wheels are provided at both ends of the synchronization rod 1531, which can slide up and down along the guide grooves on the baffles on both sides (see Figure 5). Figure 6 、 Figure 7 ).
[0041] The feeding device 2 is a flip feeding device, comprising a horizontal bracket 21, an upright auxiliary rod 22 perpendicular to the bracket 21, and flip telescopic rods 23 located on both sides thereof for driving the bracket to flip. One end of the flip telescopic rod 23 is hinged to the auxiliary rod 22 through a connecting rod, and the other end is hinged to the lower part of the two first baffles 12. A feeding sensor is also provided at the end of the bracket facing the first conveyor belt 11.
[0042] The feeding device 3 includes a second conveyor belt 31 connected to the bottom of the discharge end of the first conveyor belt 11 and second baffles 32 on both sides;
[0043] The feed sensor, the tilting telescopic rod 23 and the second conveyor belt 31 are all connected to the controller signal.
[0044] A current limiting impeller 33 is provided above the top of the second conveyor belt 31 , and both ends of the current limiting impeller 33 are supported on the second baffle 32 .
[0045] The controller includes a PLC controller and a host computer. The PLC controller is connected to the first conveyor belt 11, the second conveyor belt 31, the pressure sensor, the cutter telescopic rod 14, the pressing telescopic rod 152, the flip telescopic rod 23 and each position sensor signal.
[0046] The present invention is described in more detail below in conjunction with the working principle or process:
[0047] The cutting device is used to complete large-scale tobacco leaf cutting operations, and includes a first conveyor belt 11, a first baffle 12, a cutter 13, a power unit (i.e., a pneumatic cutting telescopic rod 14) and a pressure sensor. The first conveyor belt 11 can be a belt conveyor, which is used to receive tobacco leaves from the previous process. At the same time, the cutting process is also completed on the first conveyor belt, and the cut tobacco leaves are sent to the next process. The two baffles 12 can be made of steel parts, extending along the length direction of the first conveyor belt 11, sandwiching the first conveyor belt 11 from both sides without leaving any gaps, forming a channel for tobacco leaves to pass through, increasing the thickness of the tobacco leaves accumulated on the first conveyor belt 11, and preventing tobacco leaves from falling from both sides of the first conveyor belt 11. The cutter 13 is set between the two first baffles 12, and the power unit drives the cutting telescopic rod 14 to drive the cutter 13 to reciprocate up and down to cut the tobacco leaves on the first conveyor belt 11. Specifically, Figure 1 、 2As shown, the cutter 13 can be positioned in the middle and rear section of the first conveyor belt 11, extending parallel to the width of the first conveyor belt 11. The conveyor belt of the first conveyor belt 11 can be a cut-resistant belt. A pressure sensor is used to measure the weight added or subtracted from the cutting device and transmit the data signal to the controller. Specifically, the cutting device 1 is provided with four supporting legs at the bottom, each of which is equipped with a pressure sensor. The pressure sensor can detect the increase or decrease in tobacco leaf mass on the first conveyor belt 11.
[0048] The controller, which can be a programmable logic controller, is connected to the first conveyor belt, the pressure sensor, and the power unit. Based on the mass reduction data collected by the pressure sensor, it can calculate the real-time flow rate of the first conveyor belt. By adjusting the operating speed of the first conveyor belt, closed-loop flow control is achieved to achieve precise feeding. The controller can also control the cutting frequency of the cutter according to a predetermined frequency.
[0049] When the present invention is working, tobacco leaves enter from the feed end of the first conveyor belt, the pressure sensor detects an increase in mass, and the controller starts the power device to drive the cutting telescopic rod 14 to drive the cutter 13 to move up and down to cut the tobacco leaves. The cut tobacco leaves flow out from the discharge end of the first conveyor belt.
[0050] The intelligent feeding machine of the present invention also includes a flip feeding device 2 and a feeding device 3; the flip feeding device 2 includes a bracket 21, and the two sides of the bracket 21 close to one end of the first conveyor belt 11 are respectively hinged on the two first baffles 12, and are each provided with an auxiliary rod 22 perpendicular to the bracket 21, and a flip telescopic rod 23 is hinged between the auxiliary rod 22 and the first baffle 12; the bracket 21 is provided with a flip feeding sensor at one end facing the first conveyor belt 11; the feeding device 3 includes a second conveyor belt 31 connected to the bottom of the discharge end of the first conveyor belt 11, and second baffles 32 arranged on both sides of the second conveyor belt 31; the sensor, flip telescopic rod 23 and second conveyor belt 31 are all connected to the controller signal.
[0051] like Figure 1-5As shown, the flip feeding device 2 is arranged at the feeding end of the first conveyor belt 11, which can slowly flip the existing tobacco transfer box. The tobacco leaves are transferred from the transfer box to the first conveyor belt under the combined action of their own gravity and friction, and their orientation remains unchanged during the feeding process. The bracket can be made of steel and is used to support the bottom of the tobacco transfer box during the flipping process. Its length can be the same as the length of the tobacco transfer box, and the two sides of the bracket are respectively hinged on the two first baffles. The flip telescopic rod can be a pneumatic or hydraulic telescopic rod with a travel switch, and its two ends are respectively hinged on the auxiliary rod and the first baffle, and together with the auxiliary rod and the bracket, it forms a connecting rod mechanism. The flip feeding sensor can be a photoelectric sensor, which is used to detect whether there is a tobacco transfer box on the bracket and whether the tobacco transfer box has been completely placed on the bracket.
[0052] The bracket is initially in a flat position, with the telescopic rod extended. Once the tobacco transfer box is fully in place, the feed sensor sends a signal to the controller, which retracts the telescopic rod and pulls the bracket upward via the auxiliary rod.
[0053] The feeding device 3, which transfers the cut tobacco leaves to the next process, comprises a second conveyor belt 31 and a second baffle 32. The second conveyor belt can be a belt conveyor, with its feed end located below the discharge end of the first conveyor belt. The second baffle can be made of steel. The two second baffles sandwich the second conveyor belts, leaving no gaps between them and forming a channel for transporting the tobacco leaves. To accommodate the installation height of subsequent equipment, the second conveyor belt can be installed at an angle to raise the discharge end and facilitate feeding.
[0054] like Figure 3 、 4 As shown in Figures 5 and 6, to ensure the cutter completely cuts the tobacco leaves, its length can be greater than the width of the first conveyor belt. Therefore, a sliding slot is provided on each of the two first baffles for the cutter to pass through. The sliding slot can extend vertically, with guide rails provided on either side parallel to the sliding slot. The guide rails are slidably connected to the slider of the slide, guiding the sliding of the cutter. Furthermore, the guide rails can be T-shaped or dovetail-shaped, interlocking with the slider to prevent the slide from deviating from the track.
[0055] The cutting blade faces the first conveyor belt, and its two ends pass through the sliding slot and are hinged between the two slides through the connecting rod. When the two slides are at different heights, the two ends of the cutting plate are hinged on the adjustment cylinder that can adjust the lateral offset angle, so the cutter has space and flexibility to adjust the position. , It can be similar to guillotine cutting. Two cutting telescopic rods 14 are respectively set on the crossbeam 16 above the two sliding seams and are respectively connected to the two slides. The cutting telescopic rods 14 are driven by a pneumatic mechanism to provide power for the up and down movement of the cutter. The cutting telescopic rods can be pneumatic telescopic rods with magnetic limit switches, which can obtain signals from the magnetic limit switches when reaching the limit position.。
[0056] When cutting tobacco leaves, the slide is hinged with a connecting rod and an adjustable telescopic rod. One end of the connecting rod is hinged to the cutter, and the other end is hinged to the adjustable telescopic rod on the slide. The slide and cutter plate are hinged together via the connecting rod. A pneumatic mechanism drives the adjustable telescopic rod on the slide, which in turn drives the cutter left and right through the slide. The two second telescopic rods can extend and retract at different speeds, and the ends of the cutter fall onto the first conveyor belt one after another, cutting the tobacco leaves in a manner similar to that of existing guillotines. This reduces effort and achieves excellent cutting results when processing large batches of tobacco leaves of a certain thickness.
[0057] The cutting device 1 also includes a clamping structure 15 arranged on the side of the cutter 13 facing the flip feeding device 2, and the clamping structure 15 includes a bracket 151 connected between the tops of the two first baffles 12, a clamping telescopic rod 152 arranged on the bracket 151, a pressing piece 153 connected to the telescopic rod, and a position sensor for detecting whether tobacco leaves pass through the first conveyor belt at the bottom of the cutter 13.
[0058] like Figure 1 、 2 As shown in Figures 6, 7, and 10, the clamping structure 15 includes a bracket 151, a clamping telescopic rod 152, a clamping follower rod 15, a pressing piece 153, and the position sensor. The bracket 151 is connected between the tops of the first baffles and can be made of steel to support the entire clamping structure. The clamping telescopic rod 152 can be a pneumatic or hydraulic telescopic rod with a travel switch. There can be multiple of them, which are installed side by side on the bracket 151 and are connected to a pressing piece. The pressing piece is used to directly contact the tobacco leaves. Its extension direction is parallel to the width direction of the first conveyor belt, and its width can be slightly smaller than the width of the first conveyor belt. The position sensor can be an ultrasonic sensor, which is connected to the controller signal to determine whether there are tobacco leaves under the cutter. When the position sensor detects that a tobacco leaf has passed, the controller controls the clamping telescopic rod to start, and after the pressing piece presses down to compact the tobacco leaf, it controls the cutter to descend for cutting.
[0059] Preferably, there are at least two compression telescopic rods 152; the pressing member 153 includes a synchronization rod 1531, a connecting member 1532 and two pressure plates 1533, and multiple connecting members 1532 are connected between the two pressure plates 1533, and the multiple connecting members 1532 are all hinged to the synchronization rod 1531 and the synchronization rod 1531 is connected to multiple compression telescopic rods 152; the pressure plate 1533 is provided with multiple protruding teeth on the side facing the first conveyor belt 11.
[0060] See also Figure 1 、 2In the feeding device, a limiting impeller 33 is also provided on the part of the second baffle 32 at the top of the second conveyor belt 31. The limiting impeller 33 includes a rotating shaft rotatably connected to the second baffle 32, limiting plates evenly distributed in the circumferential direction of the rotating shaft, and a rotating motor with an output shaft connected to the rotating shaft.
[0061] The current limiting impeller is arranged on the top of the second conveyor belt and maintains a certain distance between the second conveyor belt to control the thickness of the tobacco leaves piled on the second conveyor belt, making the tobacco leaf mass flow more uniform and easier to control.
[0062] The intelligent dynamic adjustment feeding method of the present invention comprises the following steps:
[0063] S1, feeding, moving the tobacco transfer box to the bracket 21 of the feeding device, turning over the bracket 21, and transferring the tobacco leaves to the first conveyor belt 11.
[0064] Tobacco leaves that have undergone preliminary processing such as leaf swinging are generally stored in a tobacco transfer box. An opening is provided on one or both sides of the tobacco transfer box. The tobacco transfer box is placed on a bracket and the opening is aligned with the first conveyor belt. The controller starts the flipping feeding device to slowly tilt the tobacco transfer box. Under the combined action of gravity and friction, the tobacco leaves are separated from the tobacco transfer box and enter the first conveyor belt.
[0065] S2, cutting, the first conveyor belt 11 conveys the tobacco leaves to the bottom of the cutter 13, the pressing structure 15 first falls to press the tobacco leaves, and then the two ends of the cutter 13 fall successively to the surface of the first conveyor belt 11 to cut the tobacco leaves; then the cutter 13 and the pressing structure are reset and the above cutting steps are repeated.
[0066] When the first conveyor belt delivers tobacco leaves beneath the cutter, a position sensor sends a signal to the controller, which lowers the compression mechanism to compress the leaves. Simultaneously, the two ends of the cutter sequentially contact the first conveyor belt, severing the leaves in a guillotine-like fashion. Once both ends of the cutter have fallen into place, a travel switch on the second telescopic rod sends a reset signal to the controller, which resets the compression mechanism and cutter, repeating the above-described cutting process at a predetermined frequency.
[0067] S3, feeding, the first conveyor belt 11 transfers the cut tobacco leaves to the second conveyor belt 31, and the second conveyor belt 31 sends the tobacco leaves out of the feeding device. The controller controls the mass flow rate of the feeding by controlling the operating speed of the first and second conveyor belts, and uses the current limiting impeller 33 to control the thickness of the tobacco leaves accumulated on the second conveyor belt 31.
[0068] After the tobacco leaves are cut, they are fed out of the feeding device via the first and second conveyor belts. A current-limiting impeller controls the thickness of the tobacco leaves on the second conveyor belt, ensuring a more uniform mass flow rate for the final feed. Simultaneously, a pressure sensor collects data on the mass loss on the first conveyor belt, specifically the mass of tobacco leaves transferred from the first conveyor belt to the second. The controller calculates the real-time flow rate from this data and compares it with a preset target flow rate. Based on this comparison, the controller controls the operating speeds of the first and second conveyor belts, maximizing the real-time flow rate's proximity to the target flow rate, ensuring precise control of the feed rate.
[0069] Preferably, in step S1, the transfer box is transported by an automated guided vehicle (AGV). The transfer box can be transported by utilizing an existing automated guided vehicle (AGV) system to improve the level of automation and achieve unmanned operation, thereby improving production efficiency.
[0070] Preferably, in step S3, the first and second conveyor belts operate in a preset mode; the preset mode includes a continuous feeding mode and a round feeding mode; the continuous feeding mode is that the first and second conveyor belts operate continuously; the round feeding mode is that the first and second conveyor belts operate intermittently.
[0071] Specifically, the first and second conveyor belts have two preferred operating modes, including a continuous feeding mode and a round feeding mode. In the continuous feeding mode, the first and second conveyor belts operate continuously for a long time. In the round feeding mode, the first and second conveyor belts operate intermittently in a fixed cycle, each cycle consisting of working time and non-working time. After the feeding is completed during the working time, the first and second conveyor belts enter the non-working time. The controller uses a pressure sensor to measure the mass of the remaining tobacco leaves on the first conveyor belt, and then controls the mass flow of the first and second conveyor belts during the next working time based on the target feeding amount.
[0072] The above is a description of one or more embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
