Description

Technical Field

[0001] The utility model relates to a tobacco stem chopping and roasting device, belonging to the technical field of tobacco chopping and roasting tools. Background Art

[0002] For the upper tobacco leaves, during the baking process, some tobacco-growing areas and farmers have deviated in the application of some technical measures. Specifically, after baking, the upper leaves have low quality tobacco rate, more variegated colors, and stiff leaves. The internal chemical composition of the tobacco leaves is high in alkalinity and low in sugar, and the smoking quality is characterized by heavy impurities and high irritation.

[0003] To address the above-mentioned issues, existing technology involves cutting and roasting tobacco leaves with their stems at once after they have fully matured. This method, called stem-on-stem cutting, significantly reduces the stiffness of the upper tobacco leaves after roasting, resulting in a looser texture, more oil, a softer texture, and a brighter color. These leaves also avoid moldy ends. Furthermore, the phenomenon of greening and ash formation is significantly reduced, narrowing the differences in appearance quality between different leaf positions on the upper leaves and "lowering" the tobacco leaf position. Therefore, cutting and roasting has become widely used. However, during the roasting process, the applicant discovered that the existing method of cutting tobacco stems is mostly done manually using sickles, which is time-consuming and labor-intensive. Furthermore, the tobacco stems have an inclined cross-section, which can easily damage the tobacco on the upper hanging rack during roasting.

[0004] Therefore, a stem-cutting and roasting device is now needed, which can easily cut off the tobacco stems while avoiding the occurrence of inclined fractures, which is conducive to ensuring the quality of subsequent flue-cured tobacco. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a stem-cutting and roasting device that can easily cut off the tobacco stems while avoiding the occurrence of inclined fractures, which is beneficial to ensuring the quality of subsequent flue-cured tobacco; and can overcome the shortcomings of the existing technology.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The utility model discloses a device for chopping and roasting tobacco stems, which comprises an air pump. A controller and a power supply are provided on one side of the air pump. The air pump is connected to a cylinder through a pipeline. A control switch is provided on the cylinder. The control switch controls the impact and contraction of a piston rod of the cylinder. A cutter I for cutting off the entire cross section of the tobacco stem and a cutter II for cutting a partial cross section on one side of the tobacco stem are connected to the end of the piston rod.

[0008] In the above-mentioned structure, a connecting piece is provided at the end of the cylinder, a bayonet for the flue-cured tobacco stem is provided at the end of the connecting piece, and a telescopic channel for cutter I and cutter II is provided on the connecting piece, and the telescopic channel passes through from the connecting end of the connecting piece to the suspended end of the connecting piece.

[0009] As mentioned above, a connecting plate is provided between the piston rod and the cutter I and the cutter II, and the connecting plate and the piston rod are connected by bolts and nuts.

[0010] As mentioned above, the connecting piece is connected with the cylinder screw.

[0011] As mentioned above, the end of the cutter I is an arc-shaped structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. When cutting flue-cured tobacco, the utility model can cut off the tobacco stems by holding the cylinder horizontally and then controlling the cutter I to impact the tobacco stems horizontally through the control switch. The cross section of the tobacco stems is circular, which is beneficial for avoiding damage to other tobacco on the tobacco rack during tobacco curing. At the same time, during the cutting process, the cutter II can cut a notch on the cut tobacco stems, which is beneficial for the subsequent tobacco braiding and baking, so that the tobacco rope can be stuck in the notch, thereby improving the firmness and stability of the tobacco braid.

[0014] 2. The bayonet facilitates the positioning of the tobacco stems to be cut, preventing displacement of the tobacco stems during the cutting process, and improving the cutting effect and efficiency. The telescopic channel facilitates the extension and retraction of cutters I and II. At the same time, the telescopic channel runs from the connecting end of the connector to the suspended end of the connector, preventing cutters I and II from colliding with the connector when impacting and cutting the tobacco stems, causing damage.

[0015] 3. A connecting plate is provided between the piston rod and cutter I and cutter II. The connecting plate and the piston rod are connected with bolts and nuts to facilitate the replacement of the cutter.
