[0002] An important part of the leaf threshing and re-roasting homogenization formula processing is the boxing system. The first-baked tobacco leaves are conveyed to the system by belts after the leaf-laying swing table and the three-stage slitting machine. The placing machine carries the slit tobacco leaves in the form of frame bars.

[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 the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

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

[0034] like Figures 1 to 4 As shown, an embodiment of the present invention provides a compacting and shaping device for primary cured tobacco leaves, comprising: an inspection platform 1, a lifting component 2, an automatic oiling component 3, a control component 4 and a pressing plate 5; a mounting frame 7 is provided on the inspection platform 1, and the mounting frame 7 is fixedly arranged on the inspection 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 arranged on the side wall of the mounting frame 7. The sliding block 23 is arranged on the side wall of the lifting plate 21. The sliding block 23 is slidably connected with the guide rail 22. The guide rail 22 has an oil injection hole. The bottom of the lifting plate 21 is connected with the pressing plate 5 to drive the pressing plate 5 to move up and down. Specifically, the guide rail 22 is provided with arranged steel balls, which make the movement of the sliding block 23 smoother.

[0036] The automatic oil injection assembly 3 is arranged on the top of the mounting frame 7, and the automatic oil injection assembly 3 is connected to the oil injection hole for injecting lubricating oil into the oil injection hole.

[0037] The control component 4 is used to detect the number of times the pressing plate 5 moves and to control the operation of the automatic oil injection component 3 .

[0038] When in use, the up and down movement of the sliding block 23 drives the pressing plate 5 to move up and down, thereby compacting the tobacco leaves; at the same time, the control component 4 detects the number of times the pressing plate 5 moves. When the number of times the pressing plate 5 moves reaches a preset number, the control component 4 controls the automatic oil filling component 3 to work, so that the automatic oil filling component 3 injects lubricating oil into the oil filling hole, thereby being able to timely and automatically replenish the lubricating oil to the oil filling hole of the guide rail 22.

[0039] It should be noted that the above-mentioned pressing plate 5 movement times reaches the preset times, which means that when the pressing plate 5 moves up and down a certain number of times, lubricating oil needs to be added to the track to ensure smooth movement of the sliding block 23. The preset times of pressing plate 5 movement are not limited here and can be determined according to actual conditions.

[0040] The present invention sets the guide rail 22 on the side wall of the mounting frame 7, sets the sliding block 23 on the side wall of the lifting plate 21, and the sliding block 23 is slidably connected with the guide rail 22, and the guide rail 22 has an oil injection hole; the bottom of the lifting plate 21 is connected with the pressing plate 5, and the automatic oil injection component 3 is set on the top of the mounting frame 7, and the automatic oil injection component 3 is connected with the oil injection hole. When in use, the up and down movement of the sliding block 23 drives the pressing plate 5 to move up and down, and the tobacco leaves are compacted; at the same time, the control component 4 detects the number of times the pressing plate 5 moves, and when the number of times the pressing plate 5 moves reaches a preset number, the control component 4 controls the automatic oil injection component 3 to work, so that the automatic oil injection component 3 injects lubricating oil into the oil injection hole, and then the oil injection hole of the guide rail 22 can be replenished with lubricating oil in time and automatically, without stopping the equipment to replenish the lubricating oil to the oil injection hole of the guide rail 22, thereby improving the tobacco leaf processing efficiency.

[0041] Furthermore, currently, the lubricating oil is injected into the guide rail 22 manually, and it is done during the equipment shutdown for maintenance. Moreover, when too little lubricating oil is added, there is no continuous lubrication between the steel balls due to the volatile nature of the lubricating oil. If too much lubricating oil is added, the lubricating oil will overflow to the pressure rod through the gap between the guide rail 22 and the linear bearing steel balls, and combine with environmental dust to produce grease during the production process. The present invention can control the amount of lubricating oil injected into the guide rail 22 by the automatic oiling component 3 through the control component 4, thereby avoiding the problem of inconvenience caused by too little or too much lubricating oil.

[0042] Specifically, the control component 4 includes a height sensor, which is used to detect the height of the lubricating oil added to the inside of 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 device for compacting and shaping the first-cured tobacco leaves of the present invention, Figure 1 As shown, the pressing plate 5 is located below the maintenance platform 1, and the maintenance platform 1 has an opening.

[0045] The compacting and shaping device for primary-cured tobacco leaves further comprises a driving assembly 6 , which is meshed with the transmission teeth 24 .

[0046] Specifically, the driving assembly 6 works to drive the transmission teeth 24 to move, and the movement of the transmission teeth 24 drives the lifting plate 21 to move, and then drives the pressing plate 5 to move up and down, so as to compact the tobacco leaves.

[0047] In one embodiment of the device for compacting and shaping the first-cured tobacco leaves of the present invention, Figure 1 As shown, the drive assembly 6 includes a drive motor 61, a gearbox 62, and a connecting rod gear.

When the control component 4 detects that the number of times the pressure plate 5 moves reaches a preset number of times, the control component 4 controls the first-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, so as to achieve precise control of the refueling amount, so that the equipment can be regularly and quantitatively refueled without stopping the machine, and the steel balls inside the guide roller are evenly lubricated without overflowing.

[0053] Furthermore, there are two guide rails 22 , which are spaced apart and arranged in an upper row on the side wall of the mounting frame 7 .

[0054] There are two transparent oil pipes 34, and the automatic oil filling assembly 3 also includes a three-way joint 35, which is connected to the one-position two-way solenoid valve 33. The first ends of the two transparent oil pipes 34 are respectively connected to the three-way joint 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.

[0059] In one embodiment of the device for compacting and shaping the first-cured tobacco leaves of the present invention, 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 arranged at the bottom of the maintenance platform 1. The first sensor 42 and the second sensor 43 are respectively arranged on the fixed plate 46, and correspond to the highest position and the lowest position of the pressure plate 5 respectively. The controller 41 is electrically connected to the first sensor 42, the second sensor 43 and the automatic oil injection component 3 respectively. 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 oil injection component 3.

[0060] Specifically, when the pressing plate 5 moves to the highest position of the upward movement, the first sensor 42 can detect the pressing plate 5 ; when the pressing plate 5 moves to the lowest position of the downward movement, the second sensor 43 can detect the pressing 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 it to the controller 41.
