Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to a compaction and shaping device for primary flue-cured tobacco leaves. Background Technology

[0002] A crucial component of the homogenized formulation processing for re-drying tobacco leaves is the packing system. The initially dried tobacco leaves pass through a leaf-laying and stacking table and a three-stage slitting machine, then are conveyed to this system via belt conveyors. The sheet-laying machine carries the slit tobacco leaves in frames. Due to differences in tobacco grade, the leaves are often loose and overflow after entering the frames. Therefore, a compaction and shaping device is added at the second packing station. This device is driven by a motor with gears, and the pressure rod is fixed on a linear guide rail, making a linear reciprocating motion. Based on the current processing time of 18 hours, six compaction and shaping devices have a single-machine stroke of 4 km / day. According to equipment maintenance requirements, lubricating oil needs to be added to all six devices weekly. However, the lubricating oil in the guide rails is prone to evaporation, making it difficult to maintain a continuous lubrication between the steel balls, which affects the normal operation of the linear bearings on the linear rolling guide rails.

[0003] Currently, some manufacturers perform routine maintenance according to linear guide lubrication standards. However, considering the safety of adding lubricating oil, this usually needs to be done on weekends when the machine is shut down, which reduces work efficiency.

[0004] Therefore, how to provide a compaction and shaping device for first-cured tobacco leaves has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] like Figures 1 to 4 As shown, this utility model embodiment provides a compaction and shaping device for first-cured tobacco leaves, including: a maintenance platform 1, a lifting component 2, an automatic oiling component 3, a control component 4, and a pressure plate 5; a mounting frame 7 is provided on the maintenance platform 1, and the mounting frame 7 is fixedly installed on the maintenance platform 1.

[0035] The lifting assembly 2 includes a lifting plate 21, a guide rail 22, and a sliding block 23. The guide rail 22 is mounted on the side wall of the mounting bracket 7, and the sliding block 23 is mounted on the side wall of the lifting plate 21, with the sliding block 23 slidably connected to the guide rail 22. The guide rail 22 has an oil injection hole. The bottom of the lifting plate 21 is connected to the pressure plate 5 to drive the pressure plate 5 to move up and down. Specifically, the guide rail 22 is equipped with a series of steel balls, which make the movement of the sliding block 23 smoother.

[0036] The automatic oiling assembly 3 is located on the top of the mounting bracket 7 and is connected to the oiling hole for injecting lubricating oil into the oiling hole.

[0037] Control component 4 is used to detect the number of times the pressure plate 5 moves and to control the operation of the automatic oiling component 3.

[0038] During use, the up-and-down movement of the sliding block 23 drives the pressure plate 5 to move up and down, thus compacting the tobacco leaves. At the same time, the control component 4 detects the number of times the pressure plate 5 moves. When the number of times the pressure plate 5 moves reaches the preset number, the control component 4 controls the automatic oiling component 3 to work, so that the automatic oiling component 3 injects lubricating oil into the oiling hole, thereby timely and automatically replenishing the lubricating oil in the oiling hole of the guide rail 22.

[0039] It should be noted that the preset number of times the pressure plate 5 moves refers to the need to add lubricating oil to the inside of the track when the pressure plate 5 moves up and down a certain number of times, in order to ensure that the sliding block 23 can move smoothly. The preset number of times the pressure plate 5 moves is not limited here and can be determined according to the actual situation.

[0040] This invention features a guide rail 22 mounted on the side wall of a mounting frame 7, and a sliding block 23 mounted on the side wall of a lifting plate 21, with the sliding block 23 slidably connected to the guide rail 22. The guide rail 22 has an oil injection hole. The bottom of the lifting plate 21 is connected to the pressure plate 5, and the automatic oil injection component 3 is mounted on the top of the mounting frame 7, connected to the oil injection hole. In use, the up-and-down movement of the sliding block 23 causes the pressure plate 5 to move up and down, compacting the tobacco leaves. Simultaneously, the control component 4 detects the number of times the pressure plate 5 moves. When the number of times the pressure plate 5 moves reaches a preset number, the control component 4 controls the automatic oil injection component 3 to work, injecting lubricating oil into the oil injection hole. This allows for timely and automatic replenishment of lubricating oil to the oil injection hole of the guide rail 22, eliminating the need to stop the equipment before replenishing lubricating oil, thus improving tobacco processing efficiency.

[0041] Furthermore, currently, lubricating oil is injected into the guide rail 22 manually during equipment shutdown and maintenance. Insufficient lubricating oil results in insufficient lubrication between the steel balls due to its volatile nature. Excessive lubricating oil overflows through the gap between the guide rail 22 and the linear bearing steel balls, entering the pressure rod and combining with environmental dust during production to form grease. This invention addresses this issue by controlling the amount of lubricating oil injected into the guide rail 22 by the automatic lubrication component 3, thus avoiding the inconvenience caused by insufficient or excessive lubrication.

[0042] Specifically, the control component 4 includes a height sensor, which is used to detect the height of the lubricating oil added inside the guide rail 22. When the height sensor detects the lubricating oil, the control component 4 controls the automatic oiling component 3 to stop working.

[0043] In one embodiment of the compaction and shaping device for the initial cured tobacco leaves of this utility model, such as Figure 1 As shown, the pressure plate 5 is located below the maintenance platform 1. The maintenance platform 1 has an opening, and the lifting plate 21 passes through the opening and is connected to the pressure plate 5. This arrangement allows the lifting plate 21 to stably drive the pressure plate 5 to work.

[0044] In one embodiment of the compaction and shaping device for the first-cured tobacco leaves of this utility model, the sliding block 23 is disposed on the first side wall of the lifting plate 21, and the transmission gear 24 is disposed on the second side wall of the lifting plate 21.

[0045] The compaction and shaping device for the first-cured tobacco leaves also includes a drive assembly 6, which meshes with the transmission gear 24.

[0046] Specifically, the drive component 6 operates, which can drive the transmission gear 24 to move. The movement of the transmission gear 24 drives the lifting plate 21 to move, which in turn drives the pressure plate 5 to move up and down, thereby compacting the tobacco leaves.

[0047] In one embodiment of the compaction and shaping device for the initial cured tobacco leaves of this utility model, such as Figure 1 As shown, the drive assembly 6 includes a drive motor 61, a gearbox 62, and a gear on a connecting rod. The drive motor 61 and the gearbox 62 are mounted on the maintenance platform 1. The output shaft of the drive motor 61 is connected to the gearbox 62 and the first end of the connecting rod. The second end of the connecting rod is connected to the gear, and the gear meshes with the transmission gear 24.

[0048] Specifically, the gearbox 62 is used to change the rotation direction of the drive motor 61, thereby enabling the lifting plate 21 to move upward or downward.

[0049] This utility model sets up a drive motor 61 and a gearbox 62 on a maintenance platform 1. The output shaft of the drive motor 61 is connected to the gearbox 62 and the first end of the connecting rod. The second end of the connecting rod is connected to a gear. The gear meshes with the transmission gear 24. The drive motor 61 drives the connecting rod to rotate, the connecting rod rotates, and the gear rotates, which in turn drives the transmission gear 24 to move. This allows the lifting plate 21 and the pressure plate 5 to move stably.

[0050] In one embodiment of the compaction and shaping device for the initial cured tobacco leaves of this utility model, such as Figure 1 and Figure 2As shown, the automatic oil filling assembly 3 includes a bracket 31, an oil cup 32, a one-position two-way solenoid valve 33, and a transparent oil pipe 34. The bottom of the bracket 31 is fixed on the maintenance platform 1. The oil cup 32 is set on the top of the bracket 31, and the bottom of the oil cup 32 is connected to the one-position two-way solenoid valve 33. The first end of the transparent oil pipe 34 is connected to the one-position two-way solenoid valve 33, and the second end of the transparent oil pipe 34 extends into the oil filling hole. The one-position two-way solenoid valve 33 is connected to the control assembly 4.

[0051] Specifically, the oil cup 32 is filled with lubricating oil, and the control component 4 can control the opening and closing of the one-position two-way solenoid valve 33, thereby connecting the oil cup 32, the one-position two-way solenoid valve 33 and the transparent oil pipe 34, so that the lubricating oil inside the oil cup 32 is injected into the oil filling hole of the guide rail 22 through the transparent oil pipe 34.

[0052] This utility model fixes the bottom of the bracket 31 to the maintenance platform 1, sets the oil cup 32 on the top of the bracket 31, and connects the bottom of the oil cup 32 to the one-position two-way solenoid valve 33. The first end of the transparent oil pipe 34 is connected to the one-position two-way solenoid valve 33, and the second end of the transparent oil pipe 34 extends into the oil injection hole. The one-position two-way solenoid valve 33 is connected to the control component 4. When the control component 4 detects that the number of times the pressure plate 5 has been moved has reached the preset number, the control component 4 controls the one-position two-way solenoid valve 33 to open, so that the lubricating oil inside the oil cup 32 is injected into the oil injection hole of the guide rail 22 through the transparent oil pipe 34, thereby achieving precise control of the amount of oil added. This allows the equipment to be injected with oil at regular intervals and in quantitative quantities without stopping the machine, so as to evenly lubricate the steel balls inside the guide roller without overflowing.

[0053] Furthermore, there are two guide rails 22, which are respectively spaced apart and arranged on the side wall of the mounting bracket 7.

[0054] There are two transparent oil pipes 34. The automatic oil filling assembly 3 also includes a three-way connector 35. The three-way connector 35 is connected to a one-position two-way solenoid valve 33. The first ends of the two transparent oil pipes 34 are respectively connected to the three-way connector 35, and the second ends of the two transparent oil pipes are respectively inserted into the oil filling holes of the two guide rails 22.

[0055] In one embodiment of the compaction and shaping device for the first-cured tobacco leaves of this utility model, an oil receiving box 36 is also provided at the bottom of the support 31, and the oil receiving box 36 is located below the three-way connector 35.

[0056] This utility model provides an oil collection box 36 at the bottom of the bracket 31, positioned below the tee connector 35. The oil collection box 36 collects any overflowing lubricating oil, preventing it from spilling onto other structures and causing accidents.

[0057] In one embodiment of the compaction and shaping device for the first-cured tobacco leaves of this utility model, the bottom of the support 31 has a plurality of connecting holes 37, and the support 31 is fixed on the mounting frame 7 by installing fastening bolts on the plurality of connecting holes 37.

[0058] This utility model provides multiple connection holes 37 at the bottom of the bracket 31 and installs fastening bolts on the multiple connection holes 37 to fix the bracket 31 to the mounting frame 7, thereby ensuring the stability of the bracket 31 fixed on the mounting frame 7.

[0059] In one embodiment of the compaction and shaping device for the initial cured tobacco leaves of this utility model, such as Figures 1 to 4 As shown, the control component 4 includes a fixed plate 46, a controller 41, a first sensor 42, and a second sensor 43. The fixed plate 46 is located at the bottom of the maintenance platform 1. The first sensor 42 and the second sensor 43 are respectively located on the fixed plate 46 and correspond to the highest and lowest positions of the pressure plate 5, respectively. The controller 41 is electrically connected to the first sensor 42, the second sensor 43, and the automatic oiling component 3. The first sensor 42 and the second sensor 43 are used to detect the number of times the pressure plate 5 moves, and the controller 41 is used to control the operation of the automatic oiling component 3.

[0060] Specifically, when the pressure plate 5 moves to the highest position of the upward movement, the first sensor 42 can detect the pressure plate 5; when the pressure plate 5 moves to the lowest position of the downward movement, the second sensor 43 can detect the pressure plate 5.

[0061] During operation, the first sensor 42 and the second sensor 43 detect the number of times the pressure plate 5 moves up and down and transmit the data to the controller 41. The controller 41 records and counts the number of times the pressure plate 5 moves up and down. When the number of times the pressure plate 5 moves up and down reaches the preset number, the controller 41 controls the one-position two-way solenoid valve 33 to open, so that the lubricating oil inside the oil cup 32 is injected into the oil filling hole of the guide rail 22 through the transparent oil pipe 34.

[0062] After lubricating oil is injected into the oil filling hole of the guide rail 22 by the oil cup 32, the controller 41 records and counts the number of times the pressure plate 5 moves up and down again.

[0063] In one embodiment of the compaction and shaping device for the initial cured tobacco leaves of this utility model, such as Figures 1 to 4 As shown, the control component 4 also includes a power converter 44, an intermediate relay 45, and a button. The power converter 44 is electrically connected to the controller, the first sensor 42, and the second sensor 43, respectively. The intermediate relay 45 is electrically connected to the controller 41 and the automatic oiling component 3, respectively. The button is provided on the intermediate relay 45 and is used to turn the intermediate relay 45 on or off.

[0064] Specifically, the power converter 44 is used for voltage and current conversion, thereby providing protection for the controller 41, the first sensor 42 and the second sensor 43, and also improving power efficiency and enhancing power stability.

[0065] An external AC220V power supply is connected to the power converter 44, which outputs AC24V power to the controller 41, the first sensor 42, and the second sensor 43. After the pressure plate 5 completes one upward and downward compaction action, the controller 41 begins to assign values, record and count the number of upward and downward movements of the pressure plate 5. After reaching the preset number of times, the controller 41 controls the output of DC24V power to the intermediate relay 45. The normally open contact of the intermediate relay 45 closes to output DC24V power, energizing the one-position two-way solenoid valve 33. The valve opens, allowing the lubricating oil inside the oil cup 32 to be injected into the oil filling hole of the guide rail 22 through the transparent oil pipe 34.

[0066] When controller 41 disconnects the normally open contact of intermediate relay 45, the one-position two-way solenoid valve 33 is de-energized and closes, at which point oil cup 32 stops filling with oil.

[0067] In addition, the operator can manually open or close the intermediate relay 45 using a button. Specifically, when the operator presses the button, the normally open contact closes, energizing the intermediate relay 45 and the one-position two-way solenoid valve 33, allowing the lubricating oil inside the oil cup 32 to flow into the oil filling hole of the guide rail 22 through the transparent oil pipe 34. When the operator presses the button again, the normally open contact opens, de-energizing the intermediate relay 45 and the one-position two-way solenoid valve 33, stopping the oil filling of the oil cup 32.
