Description

Technical Field

[0001] The utility model relates to tobacco leaf baking, in particular to a tobacco leaf loading and unloading machine. Background Art

[0002] Tobacco curing is a crucial step in the tobacco production process. In the traditional tobacco curing process, harvested, mature leaves are first sorted, then tied to a wooden pole with ropes, 3-4 leaves in a bunch. This process is repeated repeatedly until the pole is full, and then the leaves are cured. After curing, the ropes are removed, and all the leaves on the pole are bundled. This process makes loading and unloading the tobacco leaves before and after curing time-consuming and labor-intensive, hindering production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is that, in view of the shortcomings that the current loading and unloading of tobacco leaves before and after baking is time-consuming and labor-intensive, the utility model provides a tobacco leaf loading and unloading machine which can improve the efficiency of tobacco leaf loading and unloading.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A tobacco loading and unloading machine comprises an operating table for laying tobacco leaves, a frame and tobacco clamps for clamping tobacco leaves, the operating table is arranged on the frame, the tobacco clamps comprise an upper clamp with spikes and a lower clamp with a tobacco clamping slot, the upper clamp is inserted into the lower clamp, and its structural feature is that: a fixing structure for the lower clamp to be placed is provided on one side of the operating table, one end of the fixing structure is hingedly mounted on a pressure plate via a rotating shaft, and the other end is hingedly mounted on a locking rod, a first clamping slot for the upper clamp to pass through is provided on the pressing plate, and a locking slot matching the locking rod is provided on the upper surface of the pressing plate near the locking rod end, and when the pressing plate is pressed down onto the fixing structure, the locking rod rotates into the locking slot to lock the pressing plate on the fixing structure.

[0006] When the utility model is used, before tobacco leaves are cured, the lower clip of the tobacco clip can be placed on the clamping structure of the operating table, and then the tobacco leaves are spread flat on the operating table, and the lower part of the tobacco leaves are placed on the tobacco clip slot of the lower clip. Finally, the nail teeth of the upper clip are inserted into the tobacco leaves from the top and the upper and lower clips are fixed with a buckle to complete the clamping of the tobacco leaves. After the tobacco leaves are cured, the tobacco clip containing the tobacco leaves can be placed as a whole on the clamping structure of the operating table, and then the pressing plate is pressed down on the buckle structure to separate the tobacco leaves from the nail teeth of the upper clip. At this time, the buckle of the tobacco clip is opened, the upper clip is taken out, and finally the pressing plate is opened. The tobacco leaves on the operating table are bundled and collected to complete the unloading of the tobacco leaves after curing. This makes the loading and unloading of tobacco leaves before and after curing much simpler, significantly reduces the manual participation process, and significantly improves the loading and unloading efficiency.

[0007] Furthermore, the upper and lower clamps are locked with a buckle. When the locking rod enters the locking groove, the locking rod abuts against the buckle, releasing the lock between the upper and lower clamps. In this way, when the tobacco leaves are unloaded after curing, the clamps automatically open simultaneously with the pressing plate pressing down to disengage the tobacco leaves from the spikes of the upper clamp, further improving the efficiency of tobacco unloading.

[0008] Furthermore, the fixing structure includes a second slot for accommodating the lower clip, the second slot being arranged opposite to the first slot and together forming a space for accommodating the cigarette clip. The provision of the second slot makes the cigarette clip more convenient and reliable to attach.

[0009] Furthermore, after the upper clip is inserted into the lower clip, there is a gap between the end of the upper clip and the end of the tobacco slot of the lower clip. When the locking rod enters the locking slot, the locking rod simultaneously extends into the gap, so that after the locking rod pushes against the buckle to open the cigarette clip, the locking rod can fix the lower clip on the fixing structure, making it convenient to remove the upper clip.

[0010] Furthermore, the buckle is arranged at the end of the lower clip, and anti-collision protrusions are provided around the buckle to prevent the cigarette holder from opening due to accidental collision.

[0011] Furthermore, a hydraulic rod is installed between the rotating shaft and the frame to provide a buffer through the hydraulic rod so that the pressure plate can be opened and closed safely.

[0012] Furthermore, an upper clip retractable structure is provided on the outer side of the fixing structure to facilitate temporary storage of the upper clip when it is taken out.

[0013] Furthermore, a temporary placement position for cigarette clips is provided below the operating table to facilitate the temporary storage of cigarette clips.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When loading tobacco leaves, the utility model evenly spreads the tobacco leaves on the lower clip of the cigarette clamp, inserts the lower clip, and locks the upper and lower clips with a buckle to directly complete the loading. After the tobacco leaves are roasted, the cigarette clamp is placed on the locking structure, the pressing plate is closed, and the upper clip is removed. The tobacco leaves can be unloaded and then bundled. Compared with traditional loading and unloading methods, the use of the utility model is more labor-saving, less damaged to the tobacco leaves, and the tobacco leaves are better in appearance.
