DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0037] The utility model will be described in detail below.

[0038] The modern tobacco making steps are a series of complex technological processes, mainly including tobacco leaf picking and processing, tobacco leaf grading and formula, tobacco leaf processing and manufacturing, silk making and rolling, splicing and packaging. These steps involve many special technologies and equipment. With the development of technology, the tobacco making process is constantly optimized and automated to improve efficiency and product quality.

[0039] The raw tobacco purchased from local tobacco stations is generally wrapped with hemp pieces into tobacco bales. Before the tobacco is re-dried, the tobacco bales need to be transferred from the warehouse to the separation table, and then the hemp pieces are unpacked and separated. In the prior art, manual transfer and separation are used in this process, and the specific process is as follows: warehouse workers stack the tobacco bales on a pallet, and then a plurality of forklifts transfer them to the buffer in front of each separation station, and the separation station workers timely lift the tobacco bales in the stacked pile to the separation table according to the rear-end tobacco separation speed, unpack the tobacco bales to expose the tobacco pile, and separate part of the tobacco from the tobacco pile one by one until the tobacco pile is separated into a plurality of mutually separated parts.

[0040] In the tobacco processing process, tobacco pile separation is an important link, which directly affects the subsequent processing efficiency and product quality. However, the existing tobacco pile separation process relies on manual operation, which not only has high labor intensity, but also has low efficiency, and is difficult to meet the needs of large-scale production. In addition, the instability of manual operation also affects the uniformity and stability of the tobacco pile separation, and further affects the quality of tobacco products. With the development of industrial automation technology, using intelligent tobacco bale separation devices has gradually become an important technical trend in the tobacco industry.

[0041] Therefore, it is necessary to develop a tobacco separation device that can effectively reduce the labor intensity of workers, reduce labor costs, and accurately, efficiently and stably separate the tobacco.

[0042] The utility model provides a kind of tobacco separation equipment for the above problems existing in prior art, which comprises: bearing platform, for carrying tobacco pile;Separation mechanism, including taking and placing device and moving device, taking and placing device is configured to move between bearing platform and specified position under the drive of moving device, taking and placing device includes two through pieces, each through piece is configured to be driven by first drive assembly to extend or retract;Wherein, in the state that through piece is in extension, two through pieces can be staggered through a certain thickness of tobacco and drive part of tobacco to leave tobacco pile under the drive of moving device.

[0043] Because the penetrating members can extend or retract under the drive of the first drive assembly, the two penetrating members can interlock and penetrate tobacco leaves of a certain thickness. Therefore, the two penetrating members can cooperate to separate and support tobacco leaves of a certain thickness, allowing some tobacco leaves to be separated from the tobacco pile. Since the moving device can drive the penetrating members between the carrying platform and the designated position, the moving device can bring the separated tobacco leaves to the designated position through the extended penetrating members. After retracting the penetrating members, the pick-and-place device returns to an unloaded state and returns to the carrying platform to continue penetrating some tobacco leaves, repeating this cycle until the tobacco pile is completely separated. This enables continuous separation operations with a high degree of automation, saving significant manpower. The work cycle is controllable and constant, helping to improve separation efficiency and saving time and effort. Furthermore, by controlling the first drive assembly to adjust the extension length of the penetrating members according to different production scenarios and needs, the thickness of the penetrating members inserted into the tobacco pile can be changed, thereby controlling the thickness and quantity of separated tobacco leaves. This allows the separation mechanism to be adapted to different production scenarios and needs, offering high flexibility and a wide range of applications.
