Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco leaf baling technology, specifically a baling component for an adjustable-distance tobacco leaf baling machine. Background Technology
[0002] Tobacco leaf compression is a process in which tobacco leaves are squeezed during the baling process, compressing the loose tobacco leaves into a smaller volume for easier bagging later. On common baling machines, a trolley containing tobacco leaves is pushed under a pressure plate. The pressure plate compresses the tobacco leaves, and the sides of the trolley can be opened. After the tobacco leaves are compressed, a horizontal telescopic cylinder pushes them out for bagging.
[0003] During the baling process, the main focus is on compressing the tobacco leaves inside the trolley. The extension and retraction stroke of the pressure plate is often related to the weight of the tobacco leaves. When the trolley is fully loaded, a smaller downward stroke is not needed to compress the tobacco leaves. Conversely, when the trolley is not fully loaded, a larger stroke is required. Therefore, when baling tobacco leaves of different weights, the maximum downward stroke of the pressure plate needs to be adjusted. Otherwise, the tobacco leaves may not be compressed tightly or may be over-compressed, leading to damage and difficulty in subsequent unloading. Utility Model Content
[0004] The purpose of this invention is to provide a pressing component for a tobacco baling machine with adjustable distance, so as to solve the problems mentioned in the background art.

The pressing bag is a gate-shaped structure. A track plate is fixed inside the pressing bracket. A weighing plate is installed at the center of the upper end of the track plate. A pressure plate is installed inside the pressing bracket and above the weighing plate. A hydraulic cylinder for lifting and lowering the pressure plate is fixed at the upper end of the pressing bracket. Guide rods are fixed diagonally at the upper end of the pressure plate. The upper ends of the guide rods pass through the pressing bracket and are slidably connected to the pressure plate. An end plate is fixed between the upper ends of the guide rods.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3This utility model provides a technical solution: it includes an outer frame 1, a pressing bracket 2 fixed inside the outer frame 1, the pressing bag is a door-shaped structure, a track plate 3 fixed inside the pressing bracket 2, a weighing plate 31 installed at the center of the upper end of the track plate 3, a pressure plate 4 installed inside the pressing bracket 2 and above the weighing plate 31, a hydraulic cylinder 41 fixed at the upper end of the pressing bracket 2 to drive the pressure plate 4 to rise and fall, a guide rod 42 fixed at the diagonal of the upper end of the pressure plate 4, the upper end of the guide rod 42 passing through the pressing bracket 2 and slidingly connected to the pressure plate 4, an end plate 5 fixed between the upper ends of the guide rod 42, a positioning head 6 installed at the bottom of the end plate 5, a telescopic rod 8 fixed at the upper end of the positioning head 6, a driving assembly 7 for driving the telescopic rod 8 to extend and retract at the upper end of the end plate 5, a pressure sensor 32 installed between the track plate 3 and the weighing plate 31, a ramp feeding plate 33 provided at the end of the track plate 3, and a through hole opened on the end plate 5 at the position aligned with the hydraulic cylinder 41.
[0018] The positioning head 6 consists of a mounting plate 61, a buffer pad 62, a buffer sleeve 63, and a buffer spring 64. The mounting plate 61 is fixed to the bottom of the telescopic rod 8, the buffer pad 62 is fixed to the bottom of the mounting plate 61, the buffer sleeve 63 is an open sleeve structure at the top and is fitted around the mounting perimeter, and a buffer spring 64 is fixed between the mounting plate 61 and the inner wall of the buffer sleeve 63.
[0019] The drive assembly 7 includes a fixed sleeve 71 and a synchronous motor 72. The fixed sleeve 71 is fixed to the upper end of the end plate 5 and is aligned with the telescopic rod 8. The upper end of the telescopic rod 8 is slidably connected inside the fixed sleeve 71. The synchronous motor 72 is fixed to the upper end of the fixed sleeve 71. A threaded rod 73 is rotatably connected inside the fixed sleeve 71. The upper end of the threaded rod 73 is fixed to the output end of the synchronous motor 72.
[0020] Working principle: First, connect the entire device to an external power source. After loading tobacco into the trolley, push it along the inclined loading plate 33 onto the track plate 3 and place it on the weighing plate 31. At this point, the weight of the trolley and the tobacco can be weighed to determine the loaded weight of the tobacco. Then, using the hydraulic cylinder 41, the pressure plate 4 is driven downward to compress the tobacco in the trolley. During the compression process, the guide rod 42 will drive the end plate 5 to move downward synchronously until the upper end of the end plate 5 abuts against the positioning head 6, thus limiting the continuous downward pressure of the pressure plate 4. Therefore, after obtaining the loaded weight information of the tobacco, adjust the positioning head 6. The height allows control over the downward stroke of the pressure plate 4. During adjustment, the output of the synchronous motor 72 drives the threaded rod 73 to rotate, which in turn drives the telescopic rod 8 to extend and retract, thus adjusting the height of the positioning head 6. When the positioning head 6 abuts against the upper end of the end plate 5, its buffer sleeve 63 will abut against the end plate 5 first, compressing the buffer spring 64 until the buffer pad 62 abuts against the upper end of the end plate 5. This effectively buffers the impact and protects the mechanical equipment. Finally, the pressing depth of the pressure plate 4 can be determined based on the amount of tobacco leaves in the trolley during the entire pressing process.
