Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology for leafy agricultural products, and in particular to a tobacco leaf compression and extrusion packaging mechanism. 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.

The frame system includes a tobacco leaf compressor frame 6, a tobacco leaf compressor frame base, and a tobacco leaf extrusion frame 33. The tobacco leaf compressor frame base includes a tobacco leaf compressor frame base body 1, a pair of roller strip assemblies 2, a pair of pressure-bearing beams 20, and four sets of settling components. It features a high degree of intelligence and automation, high production efficiency, safe operation, and long service life. It is used in conjunction with a tobacco leaf weighing and pre-compression device, a transition conveying device, a tobacco leaf baling and turning device, and a tobacco loading car. It can be used for compressing and baling plant leaves such as kelp and tobacco leaves, and plant stems such as rice straw and wheat straw.

[0005] Another 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 processes of tobacco leaves, labor intensity is significantly reduced and labor efficiency is improved.

[0006] Another example is the "Automatic Packaging Device and Method" disclosed in Chinese patent application (application number 202211100751.1). This automatic packaging device includes: 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, with a dropping port on the first feeding conveying mechanism 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 entire packaging process of the aforementioned automatic packaging device and method is automated, resulting in high packaging efficiency.

[0007] Another Chinese patent application (application number 202312092641.9) 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 conveying mechanism, a dropping mechanism, a second feeding conveying mechanism, 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 conveying mechanism. A section of the second feeding conveying mechanism is located below the first feeding conveying mechanism. The packing mechanism is located on the second feeding conveying mechanism 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.

[0076] The cross-section of the protective plate 4 is in the shape of the upper part of a "convex" character, and the "-" parts on its left and right sides are placed on the protective plate installation support ears 77 and fixed by installation screws, which is used to form the safety protection for the middle part of the tobacco loading vehicle conveying system.

[0077] The tobacco loading vehicle positioning system is composed of two groups of identical tobacco loading vehicle positioning components and two groups of symmetrically identical tobacco loading vehicle positioning components. Among them: one group of tobacco loading vehicle positioning components and one group of symmetrically identical tobacco loading vehicle positioning components are arranged in the front and back directions to form a left tobacco loading vehicle positioning mechanism, and the other group of symmetrically identical tobacco loading vehicle positioning components and the other group of tobacco loading vehicle positioning components are arranged in the front and back directions to form a right tobacco loading vehicle positioning mechanism; the left tobacco loading vehicle positioning mechanism and the right tobacco loading vehicle positioning mechanism are respectively arranged on both sides of the inner cavity in the middle and lower parts of the tobacco leaf compression machine frame 20.

[0078] Taking the tobacco loading vehicle positioning component as an example (that is: the tobacco loading vehicle positioning component at the front of the left tobacco loading vehicle positioning mechanism, see Figure 4 and 12 shown), it is composed of a positioning base block 21, a positioning oil cylinder 84, a positioning oil cylinder hinge pin shaft 82, a positioning oil cylinder hinge pin seat 81, a positioning oil cylinder shaft end joint 87, a positioning rod 90, a positioning rod connection hinge pin shaft 88, and a positioning rod hinge pin base shaft 89.

[0079] The positioning base block 21 is located in the middle front part of the positioning platform 50 on the left side of the inner cavity of the lower part of the tobacco compressor frame 20. The positioning cylinder hinge pin seat 81 connected to its front end is hinged to the rear end of the positioning cylinder 84 through the positioning cylinder hinge pin shaft 82. The end of the positioning cylinder shaft at the front end of the positioning cylinder 84 is hinged to the rear end of the positioning rod 90 through the positioning cylinder shaft end joint 87 and the positioning rod connecting hinge pin shaft 88. The middle part of the positioning rod 90 [shaped like a ")"] is hinged on the positioning rod hinge pin base shaft 89. The positioning rod hinge pin base shaft 89 is stepped with a larger bottom and a smaller top, and it is located in the front part of the positioning platform 50 on the left side of the inner cavity of the lower part of the tobacco compressor frame 20. The oil supply pipe 83 and the oil return pipe 86 brought by the combined control valve 28 are respectively connected to the left and front inner cavities of the positioning cylinder 84.

[0080] On the right side of the front end of the positioning cylinder 84, there is also a cylinder stop 85. The setting of the cylinder stop 85 allows the axis of the positioning rod connecting hinge pin shaft 88 and the axis of the positioning rod hinge pin base shaft 89 to form a distance difference in the left and right directions (the distance difference can be greater than 5mm). The purpose is to allow the positioning rod 90 to swing counterclockwise around the axis of the positioning rod hinge pin base shaft 89 when the positioning cylinder shaft of the positioning cylinder 84 extends forward, and also to prevent the front end of the positioning cylinder 84 from swinging excessively to the right.

[0081] The electrical control system consists of an electrical control box 46 and a control panel 7. The electrical control box 46 is located at the front of the upper cavity of the right frame of the tobacco extruder frame 22, and the control panel 7 is located at the upper left side of the tobacco compressor frame 20. The signal lines of the control panel 7 are connected to the electrical control box 46. The control lines of the electrical control box 46 are also connected to the oil pump 23, the combined control valve 28, the geared drive motor 68, and the hydraulic oil condenser 33. The signal lines of the tobacco loading car entry detection sensor 51, the tobacco loading car exit detection sensor 22, the tobacco loading car door lifting positioning detection sensor 39, the tobacco loading car door lifting positioning detection sensor plate 48, the tobacco extrusion cylinder in-situ detection sensor 34, and the tobacco extrusion cylinder extrusion end position detection sensor 28 are all connected to the electrical control box 46. The signal lines of the tobacco compression execution return positioning detection sensor 19 and the right-side tobacco loading car door lifting positioning detection sensor 27 are connected in series and then connected to the electrical control box 46.

[0082] The tobacco leaf compression and extrusion mechanism 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.

[0083] Before use, connect the tobacco weighing and pre-compression device, the transition conveyor device, and the rear side of the tobacco compressor frame 20 in sequence. Then connect the tobacco bale turning device to the bale discharge cylinder 3 on the left side of the tobacco compressor frame 20. Finally, preset various process parameters through the control screen 7 and save them to the electrical control box 46.

[0084] 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 production 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 46 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 20 (or, when the previous tobacco loading cart leaves the inner cavity of the tobacco compressor frame 20, the tobacco loading cart departure detection sensor 49 transmits the detected departure signal to the control box 46, which then commands the transition conveyor device to send the cart). When the loading cart (with its front bottom surface resting on the chain 2 from the moment it enters the inner cavity of the tobacco compressor frame 20) is detected by the loading cart entry detection sensor 48 located at the rear of the lower right side of the tobacco compressor frame 20, the sensor immediately takes over the feeding control of the transition feeding device and starts the reduction drive motor 68 via the electrical control box 46, causing the chain 2 to move the loading cart from back to front until the rear of the loading cart moves forward beyond (i.e., out of) the detection range of the loading cart entry detection sensor 48. At this point, on the one hand, the loading cart entry detection sensor 48 loses control of the feeding of the loading cart and therefore stops feeding (the loading cart has already left the feeding component of the transition feeding device); on the other hand, the loading cart leaves. The detection sensor 49 detects the entry signal from the front right side of the tobacco loading cart and then instructs the transition conveyor to stop conveying the cart via the electrical control box 46. Meanwhile, the electrical control box 46 instructs the shaft end of the positioning cylinder 84 to extend forward, thereby pushing the positioning rod 90 to swing counterclockwise around the axis of the positioning rod hinge base shaft 89 until the front end of the positioning rod 90 swings to the left and right direction, at which point the shaft end of the positioning cylinder 84 stops extending. At this time, the front end of the positioning rod 90 becomes a "bar". At the same time, the positioning rods in the other three tobacco loading cart positioning components also form similar "bars", thus forming a precise rectangular (i.e., matching the dimensions of the cuboid tobacco loading cart) positioning barrier, thereby accurately positioning the tobacco loading cart at the compression and extrusion position.

[0085] Next, via the control panel 7, the electrical control box 46 controls the tobacco compression cylinder 15, causing its downward-extending cylinder shaft to push the tobacco compression plate 9 against the inner cavity of the loading cart until the compression time and pressure reach the set values. After the tobacco compression is complete, the electrical control box 46 controls the cylinder shaft of the tobacco compression cylinder 15, along with the tobacco compression plate 9, to begin retracting upwards. When the tobacco compression execution return positioning detection rod 18 on the tobacco compression plate 9 is detected by the tobacco compression execution return positioning detection sensor 19, the cylinder shaft of the tobacco compression cylinder 15 stops retracting. Then, the electrical control box 46 controls the two loading cart lifting door cylinders 12 of the loading cart lifting door assembly to begin retracting upwards. The loading cart lifting door slot 6, located on the inner side of the loading cart lifting door crossbar 52 (when the loading cart enters the inner cavity of the tobacco compressor frame 20, the horizontal door handles on the left and right sides of the loading cart are inserted into the "ᄃ"-shaped loading cart lifting door slot 6). (Inside) The left and right side doors of the loading cart are lifted and moved upward by inserting the horizontal door handle into the door lifting slot 6. When the door lifting positioning detection sensor 25 of the loading cart door lifting detection assembly detects the door lifting positioning detection sensor plate 51 on the outer side of the door lifting crossbar 52, which is moving upward along with the left and right side doors, it indicates that the doors on both sides of the loading cart are fully opened. (The signal lines of the door lifting positioning detection sensor 25 and the right door lifting positioning detection sensor 27 are connected in series. If either one does not detect a signal, the next procedure cannot be entered.) At this time, the left door of the tobacco loading cart is directly opposite the right side of the bale discharge cylinder 3, and the right door of the tobacco loading cart is directly opposite the tobacco leaf extrusion cylinder extrusion plate 29 of the tobacco leaf extrusion cylinder assembly. Therefore, next, the electrical control box 46 controls the tobacco leaf extrusion cylinder 37 of the tobacco leaf extrusion cylinder assembly, so that its tobacco leaf extrusion cylinder shaft 30, along with the tobacco leaf extrusion cylinder extrusion plate 29, 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 plate 40 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 34. Immediately, the tobacco leaf compression and discharge cylinder shaft 30 stops extending to the left and begins to retract to the right. When the tobacco leaf compression and discharge cylinder detection sensor plate 40 retracts to the right and is below the tobacco leaf compression and discharge cylinder original position detection sensor 39, the tobacco leaf compression and discharge cylinder shaft 30 stops retracting. Then, the tobacco loading cart lifting cylinder 12 begins to extend downward until the set time, at which point the tobacco loading cart lifting cylinder 12 stops moving, and the left and right doors of the tobacco loading cart return to their original positions. Thus, one tobacco leaf compression and discharge action is completed.

[0086] Next, the operator operates the control panel 7 again, instructing the control box 46 to retract the shaft end of the positioning cylinder 84, thereby causing the positioning rod 90 to swing clockwise around the axis of the positioning rod hinge base shaft 89 until the front end of the positioning rod 90 swings to the front-back direction (i.e., reset). At this time, the shaft end of the positioning cylinder 84 stops retracting, and the positioning guide formed by the positioning rod disappears. The control box 46 then instructs the reduction drive motor 68 to start, allowing the chain 2 to continue moving the tobacco cart from back to front until the rear side of the tobacco cart moves forward beyond (i.e., disengages) the tobacco cart and leaves the detection range of the detection sensor 49. At this time, the reduction drive motor 68 stops rotating, and the tobacco cart has disengaged from the chain 2, thus entering the next cycle.

[0087] The tobacco leaf compression and extrusion packaging mechanism of the present invention 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.
