Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment for leafy agricultural products, and in particular to a tobacco leaf compression and extrusion device. Background Technology

[0002] Leafy agricultural products, such as tobacco, are bulky and loose, so after being purchased from the production base, they usually need to be weighed, packaged, and then transported to the processing plant for storage.

[0003] In the existing technology, most equipment used for weighing and packing leafy plants uses a tobacco loading cart for weighing and compressing, and then the cart door is opened for bundling and packing. This method has relatively low work efficiency and the labor intensity of the operators is relatively high.

[0004] Chinese patent application (application number 201510080922.2) discloses an "Intelligent Tobacco Leaf Packing Equipment and Method." This equipment includes multiple conveyors connected sequentially in a closed frame shape via a lifting mechanism, with one conveyor passing through a mobile tobacco cart loading area; multiple mobile tobacco carts; a packing machine that spans over another conveyor, allowing the other conveyor to pass through its interior; a rotating packing mechanism connected to the packing machine; a power source mechanism connected to the multiple conveyors to provide driving force; and a control system connected to the multiple conveyors, the packing machine, the rotating packing mechanism, and the power source mechanism. By automating the loading, pressing, packing, and sewing of tobacco leaves, this method significantly reduces labor intensity and improves labor efficiency.

[0005] Another Chinese patent application (application number 202211100751.1) discloses an "automatic packaging device and method," the automatic packaging device comprising: a control device and, respectively connected to the control device, an incoming material conveying mechanism, an inbound lifting mechanism, a storage silo, an outbound lifting mechanism, a first feeding conveying mechanism, a dropping mechanism, a second feeding conveying mechanism, a packaging mechanism, and a finished product conveying mechanism; the inbound lifting mechanism is located between the incoming material conveying mechanism and the storage silo; the outbound lifting mechanism is located between the storage silo and the first feeding conveying mechanism; a section of the first feeding conveying mechanism and the second feeding conveying mechanism are stacked; the dropping mechanism is located on a section of the first feeding conveying mechanism and the second feeding conveying mechanism, and the first feeding conveying mechanism has a dropping port corresponding to the position of the dropping mechanism; the packaging mechanism is located on the second feeding conveying mechanism and is situated to one side of the dropping mechanism. The aforementioned automatic packaging device and method automates the entire packaging process, resulting in high packaging efficiency.

[0006] Another Chinese patent application (application number 202311492641.9) discloses a "Tobacco Leaf Packing Line, Control Device, and Control Method Based on Intelligent Conveyor Vehicles." This tobacco leaf packing line includes multiple intelligent conveyor vehicles, an incoming material conveying mechanism, a vertical warehouse, a first feeding conveyor, a dropping mechanism, a second feeding conveyor, a packing mechanism, and a finished product conveying mechanism. The vertical warehouse is arranged adjacent to the incoming material conveying mechanism and the first feeding conveyor, respectively. A section of the second feeding conveyor is located below the first feeding conveyor, and the packing mechanism is located on the second feeding conveyor and adjacent to the finished product conveying mechanism. This application automatically transports the first tobacco basket to the incoming material conveying mechanism and automatically removes the finished products transported by the finished product conveying mechanism to the finished product storage area using intelligent conveyor vehicles. This enables automatic transfer of tobacco leaves before and after processing, resulting in high efficiency, low manual labor intensity, and a high degree of automation.

[0007] There is also a Chinese patent application (application number 202021020553.0) disclosing a "novel automatic tobacco baling machine," which includes: a workbench; a feeding station unit disposed on the workbench; a pre-compression station unit disposed on the feeding station unit; an unlocking and extraction module disposed on one side of the pre-compression station unit; a re-weighting station unit disposed on one side of the unlocking and extraction module; a bagging station unit disposed on one side of the re-weighting station unit; and a strapping station unit disposed on one side of the bagging station unit.

[0061] Example:

[0062] The tobacco leaf compression and extrusion bale device in this embodiment consists of a frame system, a hydraulic system, a tobacco leaf compression system, a tobacco leaf extrusion bale system, and an electrical control system.

[0063] The frame system consists of a tobacco compressor frame 6, a tobacco compressor frame base, and a tobacco extruder frame 33.

[0064] The tobacco compressor frame 6 is a rectangular frame structure (the vertical direction is greater than the front-to-back and left-to-right directions). It consists of four columns, a top frame 11, and a second-layer frame 9 (two front-to-back crossbeams are set on each side of the middle of the top frame 11 and the second-layer frame 9). The top frame 11 and the second-layer frame 9 are set from top to bottom. On the top frame 11, in the middle of the front-to-back direction, there are symmetrical tobacco loading cart lifting gates 15 arranged in the left-to-right direction. The middle side of the tobacco loading cart lifting gate 15 is tapered outward to leave a space in the middle to accommodate the tobacco compressor cylinder 16.

[0065] The tobacco compressor frame base consists of the tobacco compressor frame base body 1, a pair of symmetrically arranged roller strip assemblies 2, a pair of symmetrically arranged pressure-bearing beams 20, four sets of settlement assemblies arranged symmetrically in the front, back, left, and right directions, and positioning components for the tobacco loading cart.

[0066] The base body 1 of the tobacco compressor frame is a rectangular flat (i.e., relatively low in the height direction) double-layer box, on which the tobacco compressor frame 6 is set (at the front, back, left, and right corners).

[0067] A pair of roller strip assemblies 2 are symmetrically arranged in the front-to-back direction on the left and right sides of the base body 1 of the tobacco compressor frame, and are composed of roller strips 58 and multiple rollers 59.

[0068] The roller strip 58 is a rectangular tube. A rectangular hole is provided on the roller strip 58 where the roller 59 is installed to accommodate the roller 59. A stepped hole (i.e., an inner stepped hole) is provided at the axial center of the roller 59, in which a roller bearing 63 and a roller bearing cover 62 are installed. The roller bearing cover 62 is inserted into the upper middle cavity of the roller strip 58 by a screw pin 60, and the roller 59 protrudes 5-20mm (10-15mm is more optimized) from the top of the roller strip 58. The exposed part of the roller 59 is used to support the cigarette cart. The roller bearing cover 62 is added to prevent dust from entering.

[0069] The pressure-bearing beam 20 is a channel steel, which is symmetrically (the slots can be opposite each other or back to back; in this example, they are opposite) set between the two roller strips 58 on the base body 1 of the tobacco compressor frame. The horizontal height of the pressure-bearing beam 20 is lower than the horizontal height of the roller strip assembly 2 (i.e., the exposed outer cylindrical surface of the roller 59).

[0095] The tobacco leaf compression and extrusion device of this embodiment is used in conjunction with the tobacco leaf weighing and pre-compression device, the transition conveying device, the tobacco leaf extrusion and turning device, and the tobacco loading car.

[0096] Before use, connect the tobacco weighing and pre-compression device, the transition conveying device, and the rear side of the tobacco compressor frame 6 in sequence. Then connect the tobacco bale turning device to the bale discharge cylinder 3 on the left side of the tobacco compressor frame 6. Finally, preset various process parameters through the control screen 7 and save them to the electrical control box 32.

[0097] In operation, the tobacco loading cart is first loaded with an appropriate amount of tobacco leaves. Then, it is pushed onto the tobacco weighing and pre-compressing device for weighing. The weighed tobacco leaves are then pre-compressed to shorten the subsequent compression time, thereby improving the overall production efficiency of the line. Next, the pre-compressed tobacco loading cart is pushed onto the transition conveyor device, which automatically transports it to its waiting position. Then, when the start button on the control panel 7 is pressed, the control box 32 sends a command to the transition conveyor device, instructing it to send the waiting tobacco loading cart into the inner cavity of the tobacco compressor frame 6 (or, when the previous tobacco loading cart leaves the inner cavity of the tobacco compressor frame 6, the tobacco loading cart departure detection sensor 22 transmits the detected departure signal to the control box 32, which then commands the transition conveyor device to send the cart). When the loading cart (whose front bottom surface rests on the roller assembly 2 from the moment it enters the inner cavity of the tobacco compressor frame 6) is detected by the loading cart entry detection sensor 51 located at the rear of the lower right inner side of the tobacco compressor frame 6, the sensor immediately takes over the delivery control of the transition delivery device, controlling it to continue delivery until the rear of the loading cart moves forward beyond (i.e., out of) the detection range of the loading cart entry detection sensor 51. At this point, on the one hand, the positioning post 81 of the elastic positioning assembly 21 located at the front of the upper part of the tobacco compressor frame base body 1 blocks the front of the loading cart, preventing it from moving forward any further; on the other hand, the loading cart enters... The entry detection sensor 51 loses control over the delivery of the transition delivery device, and thus stops delivery (in fact, the tobacco loading car has already left the delivery chain of the transition delivery device at this time). On the other hand, the entry signal detected by the front right side of the tobacco loading car when the tobacco loading car leaves the detection sensor 22 will also instruct the transition delivery device to stop delivery through the electrical control box 32. Then, the electrical control box 32 controls the positioning cylinder 71 of the hydraulic cylinder positioning assembly 50 to move, so that its positioning cylinder shaft 75 pushes the positioning bar 74 to rotate into a vertical state, thereby blocking the rear side of the tobacco loading car, thus forming an accurate positioning of the tobacco loading car. At this time, the bottom surface of the tobacco loading car is completely placed on the roller bar assembly 2. Next, the electrical control box 32 controls the tobacco compression cylinder 16, causing its downward-extending tobacco compression cylinder shaft 41 to push the tobacco compression plate 4 against the inner cavity of the loading cart via the tobacco compression push plate 8, until the compression time and pressure reach the set values. During this compression process, the pressure applied by the tobacco compression cylinder shaft 41 of the tobacco compression cylinder 16 is transmitted to the roller bar assembly 2 through the loading cart, and the roller bar assembly 2 then transmits the pressure to the settling pad 57. Since the settling plate 61 is supported by the settling spring 64, under the action of pressure, the settling plate 61 will compress the settling spring 64 and settle, thereby transferring the pressure to the bearing beam 20, which is lower in height than the roller bar assembly 2, for support (at this time, the bottom of the loading cart rests on the bearing beam 20), thus avoiding the risk of the roller bar assembly 2 being crushed.After the tobacco leaves are compressed, the electrical control box 32 controls the tobacco leaf compression cylinder shaft 41 to begin retracting upwards. When the tobacco leaf compression execution return positioning detection rod 18 on the tobacco leaf compression plate 4 is detected by the tobacco leaf compression execution return positioning detection sensor 19, the tobacco leaf compression cylinder shaft 41 stops retracting. Then, the electrical control box 32 controls the two loading cart lifting door cylinders 13 of the loading cart lifting door component to begin retracting upwards. The loading cart lifting door slot 47, which is located on the inner side of the loading cart lifting door crossbar 49, is inserted into the horizontal door handles on the left and right sides of the loading cart when the loading cart enters the inner cavity of the tobacco leaf compressor frame 6. The two side doors of the tobacco loading cart (located in the door slot 47) are lifted upwards by inserting the horizontal door handle into the door slot 47. When the door positioning detection sensor 39 of the tobacco loading cart positioning detection component detects the door positioning detection sensor plate 48 on the outer side of the door lifting crossbar 49, which is moving upwards along with the two side doors, it indicates that the doors on both sides of the tobacco loading cart are fully open. (The signal lines of the door positioning detection sensor 39 and the right door positioning detection sensor 42 are connected in series; if either one does not detect a signal, the next procedure cannot proceed.) At this time, the door on the left side of the tobacco loading cart is directly opposite the right side of the bale discharge cylinder 3, and the door on the right side of the tobacco loading cart is directly opposite the tobacco leaf extrusion cylinder extrusion plate 23 of the tobacco leaf extrusion cylinder assembly. Therefore, next, the control box 32 controls the tobacco leaf extrusion cylinder 37 of the tobacco leaf extrusion cylinder assembly, so that its tobacco leaf extrusion cylinder shaft 43, along with the tobacco leaf extrusion cylinder push plate 24 and the tobacco leaf extrusion cylinder extrusion plate 23, squeezes from the right door of the tobacco loading cart to the left, squeezing the already compressed tobacco leaves in the tobacco loading cart to the right side of the bale discharge cylinder 3, and then squeezes them out from the left side of the bale discharge cylinder 3, and enters the tobacco leaf bale turning device to be bagged and tied. When the compressed tobacco leaves are squeezed out from the left side of the discharge cylinder 3, the tobacco leaf compression and discharge cylinder positioning detection sensor 35 of the tobacco leaf compression and discharge cylinder positioning detection component is just below the tobacco leaf compression and discharge cylinder extrusion end position detection sensor 28. Immediately, the tobacco leaf compression and discharge cylinder shaft 43 stops extending to the left and begins to retract to the right. When the tobacco leaf compression and discharge cylinder detection sensor 35 retracts to the right and is below the tobacco leaf compression and discharge cylinder original position detection sensor 34, the tobacco leaf compression and discharge cylinder shaft 43 stops retracting. Then, the loading cart lifting cylinder 13 begins to extend downward until the set time, at which point the loading cart lifting cylinder 13 stops moving, and the left and right doors of the loading cart return to their original positions. Thus, one tobacco leaf compression and discharge action is completed. Next, the operator steps down on the positioning pin 80 of the elastic positioning component 21, causing the positioning pin 81 to retract downwards. Simultaneously, the operator pulls the loading cart forward until it leaves the inner cavity of the tobacco compressor frame 6. At this point, the loading cart is out of the detection range of the loading cart departure detection sensor 22, and the detected departure signal is immediately transmitted to the electrical control box 32, thus entering the next cycle. At the same time, the electrical control box 32 also controls the positioning cylinder 71 of the hydraulic cylinder positioning component 50 to retract its positioning cylinder shaft 75, thereby pulling the positioning bar 74 to rotate to a horizontal position, thus preparing for the next cycle.

[0098] The present invention relates to a tobacco leaf compression and extrusion packaging device, which can be used for compressing and packaging plant leaves such as kelp and tobacco leaves, and plant stems such as rice straw and wheat straw.
