[0002] A tobacco shredder is a key piece of equipment in a cigarette manufacturing production line. Its function is to cut processed tobacco leaves or stems into shreds of a certain width that meet the requirements of the cigarette manufacturing process. Shredders are generally classified into three types according to their blade assembly and movement: straight-cut, rotary, and roller-cut. In the straight-cut type, the tobacco leaves are conveyed to the blades via a conveyor, where they are vertically cut. In existing technology, such as Chinese Patent Publication No. CN110506975A, a tobacco shredder is described, including a valve, an inlet, a discharge slope, and a machine body. A water inlet is located below the valve and connected to a boiler. A water level gauge is connected to the outside of the boiler. A conveyor belt is installed below the inlet. However, in actual use, loose tobacco leaves on the conveyor belt, which are difficult to gather, pass through the outlet, preventing the leaves blocked at the outlet from being shredded by the blades. To overcome this technical problem, this utility model provides a tobacco shredder. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] refer to Figure 1-3As shown, this utility model provides a tobacco leaf shredder, including a housing 1, a bottom conveyor belt 6 on the housing 1, and raised side plates 5 on the side walls of the housing 1. The raised side plates 5 and the housing 1 are integrally formed. A pressing conveyor belt 7 is arranged between the raised side plates 5, and the pressing conveyor belt 7 is inclined. A cutting table 20 is arranged between the housing 1, located at the end of the bottom conveyor belt 6 and in contact with the conveying surface of the bottom conveyor belt 6, so that the tobacco leaves can be conveyed to the cutting table 20 for cutting, preventing the shredder blades 17 from damaging the bottom conveyor belt 6. Guide rails 51 are arranged on opposite sides of the raised side plates 5, and the shredder blades 17 are slidably arranged between the guide rails 51. The pressing conveyor belt 7 and the pressing conveyor belt 6 are inclined. The gap between the bottom conveyor belts 6 gradually decreases near the shredder blade 17. When the tobacco leaves are relatively loose, the gradually decreasing gaps compress the tobacco leaves so that they can pass smoothly through the shredder blade 17. The bottom edge of the shredder blade 17 contacts the upper surface of the cutting table 20 or the end of the cutting table 20. When the blade contacts the upper surface of the cutting table 20, it cuts the tobacco leaves on the cutting table 20. When the blade contacts the end of the cutting table 20, the blade and the end of the cutting table 20 generate a shearing force to cut the tobacco leaves. A motor 10 is provided on one side of the machine housing 1, and a synchronization mechanism is provided on the other side for synchronously driving the bottom conveyor belt 6, the pressing conveyor belt 7, and the shredder blade 17 to slide up and down.

[0021] In some embodiments, the bottom of the housing 1 is provided with a support leg 2, and a front cover 3 is also provided on the housing 1. A humidifying pipe 4 is provided in the front cover 3, and a plurality of air holes are provided on the humidifying pipe 4 at intervals.

[0022] In actual use, the humidification tube 4 is connected to the humidifier through a pipe, so that moisture is introduced into the humidification tube 4 to humidify the dry tobacco leaves and reduce breakage during the shredding process. Of course, this humidification operation needs to be used according to the humidity of the tobacco leaves.

[0023] A crankshaft 19 is rotatably mounted between the raised side plates 5. A connecting sleeve 18 is rotatably mounted on the shredder blade 17. The connecting sleeve 18 is fitted onto the crankshaft 19. The rotation of the crankshaft 19 causes the shredder blade 17 to reciprocate up and down. A rear cover 8 is also provided on the raised side plate 5. The rear cover 8 is used to cover the crankshaft 19 and the shredder blade 17 to prevent accidental contact.

[0024] The end of the housing 1 is provided with a discharge guide groove 9 to facilitate the discharge of shredded tobacco. A sand column 21 is also provided between the housings 1, which contacts the shredding blade 17 to grind the blade 17 and prevent sticky substances from the tobacco leaves from adhering to it during the shredding process. A support column 11 is provided between the end of the housing 1 and the cutting table 20 to prevent damage to the cutting table 20 during the shredding process.

[0025] In some embodiments, the synchronization mechanism includes a first gear 12, a second gear 13, a third gear 14, and a fourth gear 15 that mesh sequentially. The first gear 12 is connected to the roller shaft of the bottom conveyor belt 6, the second gear 13 is connected to the roller shaft of the pressing conveyor belt 7, the third gear 14 is rotatably mounted on the side wall of the machine housing 1, and the fourth gear 15 is connected to the end of the crankshaft 19. A gear guard 16 is also provided on the side wall of the machine housing 1. It should be noted that among the above four gears, the fourth gear 15 is a gear with fewer teeth, while the first gear 12 and the second gear 13 have the same number of teeth and are gears with a larger number of teeth. This allows the pressing conveyor belt 7 and the bottom conveyor belt 6 to transport materials in opposite directions at a slower speed. Since the fourth gear 15 has fewer teeth, its rotation speed is faster, thereby increasing the movement speed of the shredding blade 17.

[0026] In actual use, the tobacco leaves are placed on the bottom conveyor belt 6. If the tobacco leaves are relatively dry, the humidifier can be turned on so that the tobacco leaves can be humidified when passing under the front cover 3. When the tobacco leaves pass through the pressing conveyor belt 7, they will be gradually pressed, reducing the overall thickness of the loose tobacco leaves and making it easier to enter under the shredding blade 17. When shredding, the crankshaft 19 drives the shredding blade 17 to move up and down to shred the tobacco leaves. The tobacco shreds are discharged through the discharge guide 9.

[0027] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
