[0008] In addition, particularly preferably, the tool body is adjustably installed on the tool rest by screws.

[0009] In addition, particularly preferably, both the pressure roller and the output rubber roller are made of rubber material.

[0010] The beneficial effects are as follows: In the present utility model, the tobacco leaves are driven forward by a horizontal conveyor belt and gently pressed by a rubber roller with appropriate softness and hardness. When the tobacco leaves pass quickly, the cutter body will scrape off the stalks of the tobacco leaves, separating the tobacco leaves from the stalks. Immediately behind the cutter holder, a recovery tray is installed above to collect the scraped tobacco stalks, and an output rubber roller is installed below to convey the tobacco leaves out of the frame. The present utility model greatly improves the efficiency of stalk scraping, saves labor, and also improves the uniformity and quality of the tobacco leaves. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In the reference numerals of the drawings: 1 - conveying roller, 2 - conveyor belt, 3 - pressure roller, 4 - cutter holder, 5 - cutter body, 6 - recovery tray, 7 - output rubber roller, 8 - frame, 9 - tobacco leaves. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0014] Unless otherwise defined, all terms in this specification have the same meaning as commonly understood by those skilled in the art. If there is a conflict between the terms used in this specification and their common meaning, the definition used in this specification shall prevail. The utility model described below is used to illustrate the embodiments of the present utility model and does not limit the scope of rights of the present utility model. Throughout the specification, the same reference numerals are used for the same components.

[0015] As Figure 1 shown in the tobacco leaf stalk scraping machine, which includes a frame 8 and a horizontal conveyor belt, a pressure roller 3, an output rubber roller 7 and a cutter body 5 installed on the frame 8. Among them, the side of the tobacco leaf that needs to remove the stalks is placed face up on the horizontal conveyor belt (usually the back of the tobacco leaf). When the tobacco leaf is conveyed forward by the horizontal conveyor belt, it first passes through the bottom of the pressure roller 3. The cooperation between the pressure roller 3 and the horizontal conveyor belt completes the conveyance and pressing of the tobacco leaf, and then continues to be conveyed forward. After passing through the inclined cutter body 5, the raised part of the stalk on the tobacco leaf contacts the cutter body 5, and the two move relative to each other, so that it is removed. The tobacco leaf is conveyed into the bottom of the output rubber roller 7 along the bottom of the cutter body 5, and the output rubber roller 7 cooperates with the horizontal conveyor belt to convey it out of the stalk scraping machine. The scraped tobacco stalk filaments are conveyed upward along the cutter body 5 and collected in the recovery tray 6.

[0016] By using this stalk scraping machine, not only labor is saved, the efficiency of stalk scraping is improved, but also the stalk scraping is uniform, further improving the quality of the tobacco leaves, and solving the industry problems of low yield, poor uniformity and large loss in tobacco leaf production for tobacco farmers.

[0017] In addition, it should be noted that the horizontal conveyor belt includes a pair of conveyor rollers 1 spaced apart on a frame 8, and a conveyor belt 2 wound around the two conveyor rollers 1. The two conveyor rollers 1 are connected by a sprocket structure or a pulley structure. The present embodiment preferably uses a pulley structure with less noise, and one of the conveyor rollers 1 is connected to the motor.

[0018] The pressure roller 3 and the output rubber roller 7 are located directly above the horizontal conveyor belt. The rotation direction of the pressure roller 3 and the output rubber roller 7 is consistent with the conveying direction of the horizontal conveyor belt. The two ends of the pressure roller 3 and the output rubber roller 7 are respectively fixed on the frame 8 through the shaft support structure. The pressure roller 3 is set near the feeding end of the horizontal conveyor belt, and the output rubber roller 7 is set near the discharging end of the horizontal conveyor belt. Multiple pressure rollers 3 can be set. In this embodiment, two pressure rollers 3 are set in front and behind. By setting the pressure roller 3, on the one hand, the tobacco leaves can be flatter, and on the other hand, they can be pressed when scraping the stems to prevent the tobacco leaves from sliding relative to the horizontal conveyor belt and affecting the scraping speed. The pressure roller 3 and the output rubber roller 7 cooperate with the conveyor belt 2 to complete the pressing of the feeding and discharging of the tobacco leaves. The material of the pressure roller 3 and the output rubber roller 7 is selected from rubber materials with appropriate hardness and softness, which can not only realize the pressing and conveying function, but also minimize the damage to the tobacco leaves.

[0019] A knife holder 4 for mounting a knife body 5 is provided between the pressing roller 3 and the output rubber roller 7. The knife holder 4 is fixedly connected to the frame 8. The knife body 5 is adjustably mounted on the knife holder 4 by one or two screws. The adjustment includes installation height adjustment and installation angle adjustment. The blade of the knife body 5 extends downward to the bottom of the pressing roller 3. Specifically, the inclination angle of the knife body 5 is 15 to 60°, and the gap between the knife blade and the horizontal conveyor belt is 3 to 5 mm. In this embodiment, the inclination angle of the knife body 5 is preferably 45°, and the gap between the knife blade and the horizontal conveyor belt is 4 mm. At this angle, the tobacco stem peeling effect is better, and the process of entering the recovery tray 6 is smoother. For tobacco leaves of various varieties with different thicknesses and stem thicknesses, the above-mentioned blade gap can be adjusted to adapt.

[0020] One end of the recovery plate 6 is connected to the back end of the blade body 5, and the connection between the two is smoothly transitioned by chamfering. The recovery plate 6 is generally set horizontally, and the shaved stems enter the recovery plate 6 and are collected, thereby realizing the separation of tobacco leaves and stems.
