Description

Technical Field

[0001] The utility model relates to the technical field of metering and packaging of leafy plants, in particular to an improved mobile weighing and extruding package-out type tobacco leaf packaging machine. Background Art

[0002] Leafy agricultural products, such as tobacco and kelp, are bulky and loose. Therefore, after being purchased at production bases, they typically need to be weighed and packaged before being transported to processing plants for storage. Existing equipment for weighing and packaging leafy plants typically compresses and bundles the leaves, then wraps them in hemp sheets. This approach is inefficient and also presents challenges such as complexity, bulk, and significant space requirements.

[0003] The Chinese patent (CN117502679A) discloses a "mobile weighing and extruding tobacco baler", which includes a frame assembly, a box assembly, a compression assembly, a weighing assembly, a hydraulic assembly, an electronic control assembly and a moving assembly, as well as an extrusion and packaging assembly composed of an extrusion component and a packaging component 32; the frame assembly includes a vertical compressor frame component and a horizontal extrusion frame component, the compression assembly and the box assembly are respectively arranged at the upper and lower parts of the compressor frame component, the hydraulic assembly and the electronic control assembly are arranged at the upper part of the extrusion frame component, and the weighing assembly and the moving assembly are sequentially arranged at the lower part of the frame assembly; it has the characteristics of small size, light weight, accurate weighing, easy use, long service life, and integrates the functions of weighing, compression, bagging, etc., and can be used for weighing, compressing and bagging tobacco leaves, and can also be used for weighing, compressing and bagging leafy and stem agricultural products such as rice straw, wheat straw and kelp.

[0004] Another Chinese patent (CN216685162U) discloses a "tobacco baling machine" consisting of a frame, a fixed silo, a sliding silo, a vertical pressing device, a finished product pushing device, and a discharge channel. The sliding silo is provided with a guide rod and a drive mechanism, and an automatically retractable sliding door is provided on one side of the finished product pushing device. The discharge channel is provided with a floating cover. Tobacco leaves of a set weight are placed in the silo, the sliding silo is translated to a fixed position, the vertical pressing device compresses and packs the leaves downward, the sliding silo is withdrawn, the sliding door extends to fix the tobacco blocks, and the finished product pushing device pushes the tobacco blocks out through the discharge channel into sacks. The pressing process of this utility model requires fewer movements, the sliding silo can effectively reduce tobacco leaf breakage and improve the safety of equipment operation. The pressing, forming, and pushing processes are completed in one go, which significantly improves work efficiency and reduces the number of workers and labor intensity.

[0005] There is also a Chinese patent (CN217309114U) that discloses a "new tobacco baler" that includes a baling box with inlet and outlet holes on the opposite side walls. A closing plate that fits the outer edge of the inlet and outlet holes is also installed on the outer wall of the baling box in a vertical sliding manner. A delivery belt is also installed in the baling box to rotate horizontally. The two ends of the delivery belt pass through the two inlet and outlet holes and extend to the outside. A support platform is also horizontally provided on one side of one of the inlet and outlet holes. The upper surface of the support platform is flush with the upper surface of the delivery belt. This utility model solves the problem that after the device in the traditional technology packs the tobacco leaves, the operator needs to take the packed tobacco leaves out of the platform, which is cumbersome, time-consuming and labor-intensive; and before the tobacco leaves are put in, the operator needs to manually open and close the door, which increases the labor intensity. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to provide a tobacco packaging equipment which has a simple appearance, small size, light weight, accurate weighing, easy use, long service life, low noise, and integrates the functions of weighing, compression, bagging, etc.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is to design an improved mobile weighing extrusion-packing tobacco baler: comprising a frame assembly, a box assembly, a compression assembly, an extrusion-packing assembly, a weighing assembly, a hydraulic assembly, an electronic control assembly and a moving assembly; the frame assembly comprises a vertical compressor frame member and a horizontal extrusion frame member 9, forming an "L" shape; the compression assembly and the box assembly are respectively arranged at the upper and lower parts of the compressor frame member, and the weighing assembly and the moving assembly are sequentially arranged at the lower part of the frame assembly; the extrusion-packing assembly comprises an extrusion member and a packing member 29, the extrusion member is arranged in the extrusion frame member 9, and the packing member 29 is arranged at the lower left part of the compressor frame member; the electronic control assembly comprises an electric control box 7 and a start-stop switch 10, and the start-stop switch 10 is arranged at the middle front part of the right side of the compressor frame member;

[0008] The hydraulic assembly includes an oil tank 37, an oil pump 36, an oil pump motor 38, and a multi-way control valve 8. The oil tank 37 is arranged at the right rear part of the inner cavity of the extrusion frame member 9, and the oil pump 36 and the oil pump motor 38 are respectively arranged at the left and right parts of the upper part of the oil tank 37; the multi-way control valve 8 is arranged at the left front part of the right part of the inner cavity of the extrusion frame member 9;

[0009] The electric control box 7 is arranged at the right front portion of the right portion of the inner cavity of the extrusion frame member 9 .

[0010] The weighing assembly includes a weighing component and a weighing display component. The weighing component is arranged at the lower part of the frame assembly. The weighing display component includes a weighing display screen 12 and a weighing display screen mounting bracket 11; the weighing display screen mounting bracket 11 is arranged in the middle of the right side of the compressor frame component, and the weighing display screen 12 is arranged on it.

[0011] A mains power input socket 3 is also provided at the lower right side of the extrusion frame member 9 .

[0012] The mains power input socket 3 is an aviation socket.

[0013] This improved mobile weighing and extruding tobacco baler utilizes a single-chassis design with dual compression cylinders. This results in a compact, lightweight, and cost-effective design, making it suitable for small tobacco collection stations. Utilizing the principle of three points forming a plane, the machine employs three load cells for weighing and metering, ensuring that each load cell is consistently under load, resulting in high weighing accuracy. Furthermore, a mobile assembly has been added to its base, making it easier to move around. Furthermore, during the compression and bagging process, only two handles are required, aside from loading and bagging, making it extremely convenient to use. In addition, placing the hydraulic assembly and the electric control box in the inner cavity of the extruder frame not only makes the product's appearance simpler, but also prevents many exposed parts of the hydraulic assembly from being contaminated by oil and dust and accelerating aging and failure, thereby extending the service life of the equipment. In addition, a supporting wheel component is provided in the extrusion component to ensure that the axis of the extrusion cylinder shaft in the extrusion component is consistent with the axis of the inner hole of the extrusion cylinder, which can not only prevent the extrusion cylinder shaft from being deformed, but also reduce the wear of the extrusion component on the inner plate of the box on the bottom surface of the tobacco compression cavity and the inner cavity bottom surface of the package discharge component, thereby further extending the service life of the equipment. In addition, since the hydraulic assembly is placed in the inner cavity of the extruder frame, the noise it generates is sealed, thereby greatly reducing the noise of the entire machine.

The packing component 29 is a thin-walled tube with a rectangular cross-section (its inner wall is the same as the inner surface of the inner plate 40 of the box body, which remains smooth and can reduce friction during extrusion). Its left end is used to fit the sack wrapped with tobacco leaves, and the right end is connected to the left side of the lower part of the tobacco compression cavity 26.

[0033] The extrusion component is composed of an extrusion cylinder 4, an extrusion plate 32, an extrusion lining plate 41, an inner plate 40 of the box body and a supporting wheel component.

[0034] The extrusion cylinder 4 is installed in a left-right direction, with the left portion being arranged on the extrusion cylinder mounting crossbeam 39 in the middle of the right end of the inner cavity of the extrusion frame member 9 and fixed with an extrusion cylinder clamp 42. The extrusion cylinder flange 34 at the left end of the extrusion cylinder 4 is fixed by bolts between two extrusion cylinder mounting frame crossbeams 47 (angle steel is used in this example) arranged above and below the extrusion cylinder mounting frame 35. The end of the extrusion cylinder shaft 33 extending from the left end of the extrusion cylinder 4 is connected to the extrusion plate 32, the extrusion lining plate 41 and the box inner plate 40 in sequence.

The front and rear ends of the lower beam 2 are placed on the two universal casters 1 of the mobile component. The weighing component is provided with three weighing sensors, which are arranged according to the principle of three points (two on the left and one on the right) forming a plane. This ensures that each weighing sensor can sense gravity, so it can avoid the phenomenon that individual weighing sensors are not under force (i.e., working without exerting force) when four weighing sensors are used. The weighing display screen 12 (the direction of the weighing display screen 12 is adjustable) is respectively connected to the directional end weighing sensor 28 and the universal end weighing sensor 5 through signal lines. The weighing parameters can be set on the weighing display screen 12, such as gross weight, net weight, overweight alarm, etc.

[0038] Directional end weighing sensor protection plates 27 are respectively installed under the front and rear sides of the left side of the base frame 25 to protect the directional end weighing sensor 28 from being hit by other objects during movement or use.

[0039] The compression assembly consists of a compression component, a guide component, and a smoke compression plate 14. The compression component comprises a compression cylinder 18 and a compression plate 15. The end flange of the compression cylinder 18 is located in the middle of the top frame 16, and the lower end of the downwardly extending compression cylinder shaft 17 is connected to the compression plate 15. The guide component comprises one or two (two in this example) guide mechanisms, which are located on the top frame 16, on the left and right sides of the compression cylinder 18 (symmetrically arranged). The guide mechanisms comprise a guide rod 19, a guide sleeve 20, and a guide rod end plate 21. The guide sleeve 20 is located on the top frame 16, and the guide rod 19 is inserted into the guide sleeve 20, with its lower end connected to the guide rod end plate 21. The lower sides of the compression plate 15 and the guide rod end plate 21 are connected to the smoke compression plate 14 (the lower side of the smoke compression plate 14 is as smooth as the inner surface of the inner plate 40 of the housing). The compression cylinder 18 is connected to the multi-way control valve 8 of the hydraulic assembly via an oil pipe.

[0040] The hydraulic assembly consists of an oil tank 37, an oil pump 36, an oil pump motor 38, and a multi-way control valve 8. The oil tank 37 is located at the right rear portion of the extrusion frame member 9 (i.e., behind the extrusion cylinder 4). The oil pump 36 and oil pump motor 38 are mounted on its left and right sides, respectively. The pump body (i.e., the oil inlet) of the oil pump 36 is submerged in the oil tank 37. The output shaft of the oil pump motor 38 is connected to the power input of the oil pump 36 (driving the oil pump 36 to rotate). The multi-way control valve 8 is located on the left side of the right front portion of the extrusion frame member 9 (i.e., the front left side of the extrusion cylinder 4). The oil pump 36 is connected to the multi-way control valve 8 via oil pipes. The multi-way control valve 8 is, in turn, connected to the compression cylinder 18, the extrusion cylinder 4, and the oil tank 37 via oil pipes. A pressure gauge (not shown in the drawings) is also installed on the multi-way control valve 8 to monitor the oil pressure. A compression cylinder control rod (not marked in the drawings) and an extrusion cylinder control rod (not marked in the drawings) as well as a pressure regulating valve (not shown in the drawings) are also provided on the multi-way control valve 8, which are used to control the compression cylinder 18 and the extrusion cylinder 4 respectively.

[0041] The electronic control assembly consists of a start / stop switch 10, an electrical control box 7, and a mains power input socket 3 (an aviation socket is used in this example). The start / stop switch 10 is mounted in the center front portion of the right side of the compressor frame member and is provided with start and shutdown buttons. The electrical control box 7 is mounted on the right side of the right front portion of the inner cavity of the extruder frame member 9 (i.e., the front right portion of the extrusion cylinder 4) and is provided with an emergency shutdown switch and a power indicator light (neither of which is marked in the accompanying drawings). The mains power input socket 3 is mounted on the right end of the base frame 25 at the lower right side of the extruder frame member 9. The mains power input socket 3 is connected to the electrical control box 7, which is in turn connected to the start / stop switch 10 and the oil pump motor 38 via control lines.

[0042] Cover panels are installed on the top, front, back and right sides of the extrusion frame member 9, among which: the right cover panel is provided with a hole for allowing the extrusion cylinder 4 to extend out, the front cover panel is provided with holes for allowing the compression cylinder control rod and the extrusion cylinder control rod to extend out, as well as a hole in front of the exposed electrical control box 7.

[0043] Before use, move the improved mobile weighing and squeezing tobacco baler of the present invention to a slightly spacious place, turn on the power, set the weighing parameters on the weighing display screen 12, and adjust the upper limit value of the oil pressure (usually set to 10MPa) through the pressure regulating valve, and then it can be used.

[0044] When in use, first open the front and rear loading doors 23, and arrange the tobacco leaves to be packaged in the tobacco compression cavity 26 in the left and right directions, and layer by layer (that is, if the tobacco leaf stalks are placed at the left end of the lower layer, the tobacco leaf tips are placed at the left end of the upper layer). When the tobacco leaves are filled to exceed the upper end of the tobacco compression cavity 26, close the front and rear loading doors 23 and continue loading until the tobacco leaves filled in the tobacco compression cavity 26 reach the set weight value. At this time, the weighing display screen 12 will sound an alarm. Next, press the start button on the start-stop switch 10 to start the oil pump 36; next, put the open end of the sewn tobacco sack on the left end of the bag outlet member 29 and insert it completely; then, move the compression cylinder control lever, the compression cylinder 18 starts to work, and the compression cylinder shaft 17 of the compression cylinder 18 extends downward and pushes the compression plate 15 together with the tobacco pressing plate 14 to compress the tobacco leaves in the tobacco compression cavity 26. When the tobacco pressing plate 14 can no longer compress downward in the tobacco compression cavity 26, the pressure in the oil circuit will exceed the set value ( That is: more than 10MPa), at this time, the pressure regulating valve will automatically release the excess pressure and maintain the current position state; at the same time, the position of the tobacco pressing plate 14 is slightly lower than the inner surface of the upper wall of the inner cavity of the package discharging component 29, so that the squeezing plate 32, the squeezing lining plate 41 and the inner plate 40 of the box can be allowed to enter the inner cavity of the package discharging component 29; then, move the squeezing component operating lever, the squeezing cylinder 4 starts to work, and the squeezing cylinder shaft 33 extending from the left end of the squeezing cylinder 4 drives the squeezing plate 32, the squeezing lining plate 41 and the inner plate 40 of the box to press the tobacco leaves to the left. The compressed tobacco leaves in the tobacco compression cavity 26 are pushed to move toward the inner cavity of the packing component 29 on the left side of the tobacco compression cavity 26, and then enter the tobacco sack set on the left end of the packing component 29. As the squeezing cylinder 4 continues to squeeze, the tobacco leaves entering the tobacco sack will stretch to the left with the tobacco sack set on the left end of the packing component 29. When the squeezing cylinder shaft 33 extending from the left end of the squeezing cylinder 4 moves to the left side of the tobacco compression cavity 26 with the squeezing plate 32, the squeezing lining plate 41 and the box inner plate 40, It will continue to move to the left and enter the inner cavity of the bag-discharging member 29 until the extrusion cylinder shaft 33 of the extrusion cylinder 4 extends to the extreme left end (at this time, the extrusion cylinder 4 will stop working and maintain the current state unchanged). At this time, the compressed tobacco leaves in the tobacco compression cavity 26 are just completely squeezed into the tobacco bag, and the extrusion lining 41 and the box inner plate 40 are just at the left end of the bag-discharging member 29. At this time, the tobacco bag can be dragged away and its right end is sewn together. At this point, the weighing, compression and bagging operations are completed. Afterwards, the extrusion member operating lever is moved again, and the extrusion cylinder shaft 33 of the extrusion cylinder 4 drives the extrusion plate 32, the extrusion lining 41 and the box inner plate 40 to move to the right and reset; then, the compression cylinder operating lever is moved again, and the compression cylinder shaft 17 of the compression cylinder 18 brings the compression plate 15 and the tobacco pressing plate 14 upward and reset.

[0045] In the process (including the reset return stroke) in which the extrusion cylinder shaft 33 of the extrusion cylinder 4 drives the extrusion plate 32, the extrusion lining plate 41 and the box inner plate 40 to move into the tobacco compression cavity 26 on the left and into the inner cavity of the package discharging component 29, the support wheel 43 arranged at the lower right side of the extrusion lining plate 41 rolls along the box inner plate 40 at the bottom of the tobacco compression cavity 26 and the inner cavity bottom surface of the package discharging component 29 to ensure that the axis of the extrusion cylinder shaft 33 is consistent with the axis of the inner hole of the extrusion cylinder 4. Therefore, it can not only avoid deformation of the extrusion cylinder shaft 33, but also reduce the wear on the box inner plate 40 at the bottom of the tobacco compression cavity 26 and the inner cavity bottom surface of the package discharging component 29, thereby extending the service life of the equipment.

[0046] When the compression cylinder 18 is working, since the pressure generated by the compression cylinder 18 acts inside the frame assembly, it will not affect the weighing assembly arranged under the base frame 25 of the frame assembly (that is, the directional end weighing sensor 28 and the universal end weighing sensor 5 will not be damaged due to excessive pressure), and will not damage the moving assembly arranged below the weighing assembly (that is, the directional caster 31 and the universal caster 1 will not be damaged).

[0047] Since the direction of squeezing and pushing out the tobacco leaves is the length direction of the tobacco leaves, and the inner wall of the pushing channel is relatively smooth, the quality of the tobacco leaves will not be damaged like the horizontal pushing method.

[0048] The improved mobile weighing and extruding tobacco baler of the utility model can be used for weighing, compressing, bagging and packaging tobacco leaves, and can also be used for weighing, compressing, bagging and packaging leafy and stem agricultural products such as rice straw, wheat straw and kelp.
