Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a rotary roller for tobacco storage cabinets. Background Technology

[0002] Tobacco storage cabinets play a crucial role in tobacco production and processing. They are used to store pre-processed tobacco leaves, shredded tobacco, or stems, ensuring they remain in good condition before further processing. They provide a stable and suitable storage environment, helping to maintain the tobacco's moisture and aroma and preventing spoilage. In some production processes, the tobacco in the cabinet needs to undergo fermentation for a certain period to improve its flavor and combustion characteristics. The cabinet can control the internal temperature and humidity, promoting uniform fermentation. By storing tobacco in cabinets, quality monitoring and classification management can be implemented, ensuring that only tobacco raw materials meeting standards enter the next process, which is essential for maintaining the quality of the final product. As a buffer in the production process, tobacco storage cabinets balance the material flow on the production line, resolving issues of uneven production rates or temporary changes in supply and demand, ensuring production continuity and efficiency. The tobacco leaves, shredded tobacco, and stems stored in the cabinets are finally transported out as semi-finished products via a bottom conveyor belt and rotating rollers.

[0003] Currently used tobacco storage cabinets are divided into two types: open cabinets and closed, top-mounted cabinets. Their agitator rollers are typically slender cylindrical with rakes on the outer surface. These agitator rollers are as described in patent documents CN115611024A or CN214802250U. However, existing agitator rollers have some drawbacks and shortcomings, as follows:

[0004] The rake nails on the roller are conventionally arranged in a cylindrical shape. Their loosening ability is not high, requiring multiple rotations and repeated feeding to loosen and output the semi-finished material. This causes the tobacco to break apart during repeated loosening, increasing waste and affecting product quality. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a dispensing roller for tobacco storage cabinets. By replacing the rakes on the roller with a multi-level tree-fork shape, and by installing rakes of different lengths according to the material dispensing situation based on the rake position, the material dispensing efficiency of the rakes is improved, and the number of rakes is reduced while achieving better material dispensing. Specifically, the technical solution of this utility model to achieve the above objectives is as follows:

[0006] A push roller for a tobacco storage cabinet, disposed on one side inside the tobacco storage cabinet, is used to loosen and push out the stored materials inside the tobacco storage cabinet, comprising:

[0007] The roller shaft is cylindrical and can be connected to a power mechanism at both ends, which can drive the roller shaft to rotate.

[0008] The rake includes a main rake and a secondary rake. The roller shaft has several main mounting positions, and the main rake is mounted on the main mounting positions. The main rake has several secondary mounting positions, and the secondary rake is mounted on the secondary mounting positions.

[0009] Furthermore, the main mounting positions are connected sequentially along the axial direction of the roller shaft in a spiral shape, and the spacing between two adjacent main mounting positions is the same.

[0010] Furthermore, the main rake nail includes an installation section and a bending section; one end of the installation section is installed on the main mounting position, and the other end is fixedly connected to the bending section. The bending section and the installation section form an angle greater than or equal to 150° and less than 180°, and the bending section is offset relative to the installation section in the rotation direction of the roller shaft; the auxiliary mounting positions are arranged opposite to each other on the installation section and the bending section; the auxiliary rake nail is cylindrical, and when installed on the auxiliary mounting position, the axial direction of the auxiliary rake nail is parallel to the axial direction of the roller shaft; when the installation section is installed on the main mounting position, the installation section is perpendicular to the axial direction of the roller shaft.

[0011] Furthermore, both the main mounting position and the secondary mounting position are provided with internal threads, and the mounting section and the bent section are respectively installed on the main mounting position and the secondary mounting position by threads.

[0012] Furthermore, the installation section and the bending section are each provided with two pairs of auxiliary mounting positions; the auxiliary rake nails include three lengths: 5cm, 7.5cm and 10cm; the 10cm auxiliary rake nails are installed on the installation section, the 7.5cm auxiliary rake nails are installed on a pair of auxiliary mounting positions on the bending section near the installation section, and the 5cm auxiliary rake nails are installed on a pair of auxiliary mounting positions at the end of the bending section.

[0013] Furthermore, the main mounting position includes a rotary mounting seat and a torsion spring. The roller shaft has a mounting groove, and the rotary mounting seat is installed in the mounting groove. The rotation axis of the rotary mounting seat is parallel to the axial direction of the roller shaft. The rotary mounting seat has a threaded hole perpendicular to the rotation axis and extending outward from the mounting groove for installing the main rake nail. The torsion spring is installed below the rotary mounting seat in the mounting groove to support the rotary mounting seat. The rotary mounting seat can rotate downward by 15° and be reset by the spring force.

[0014] Furthermore, a retaining sleeve is provided outside the mounting groove; the retaining sleeve is made of flexible material; mounting holes are formed around the mounting groove; the retaining sleeve is a hollow truncated cone structure, with a pressure ring at one bottom end, which is fitted and fixedly installed on the mounting hole against the outer surface of the roller shaft; a sealing ring is provided at one top end of the retaining sleeve along the axial direction of the truncated cone, the diameter of the sealing ring being the same as the diameter of the main rake nail; the main rake nail passes through the sealing ring and the bottom end of the retaining sleeve in sequence and is then connected and installed on the rotating mounting base. The retaining sleeve is used to block material and prevent material from getting stuck in the mounting groove.

[0015] In use, one end of the mounting section 22 of the grab rake nail 2 is passed through the sealing ring 42 on the bottom of the retaining sleeve 4, slid into the retaining sleeve 4, and then passed through the bottom of the retaining sleeve 4 and rotated to install in the threaded hole of the rotating mounting base 13 and tightened. Then, the pressure ring 41 on the bottom of the retaining sleeve 4 is fixedly installed on the mounting holes around the mounting groove 12 for sealing. Then, the 10cm long auxiliary rake nail 3 is installed in sequence on the main mounting position 11 on the mounting section 22 of the grab rake nail 2, and then the 7.5cm auxiliary rake nail 3 is installed in sequence on a pair of auxiliary mounting positions 21 near the mounting section 22 on the safety end 23. Finally, the 5cm auxiliary rake nail 3 is installed on a pair of auxiliary mounting positions 21 at the end of the safety end 23. When the grab rake nail 2 is subjected to greater pressure, the rotating mounting base 13 and the torsion spring 14 provide space for it to rotate 15° in the opposite direction of the rotation of the roller shaft, which plays a buffering role. This design is for safety; if a worker accidentally gets stuck in the rake nail during misoperation, they can press down firmly on the rake nail to prevent being pulled in. Existing rake nails lack a buffer structure; although the roller rotates very slowly, if items such as belts or clothing get caught in them during misoperation, they are still difficult to remove and can easily be pulled in.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The storage tank paddle roller designed in this utility model, through its tree-fork-like structure, allows the rake nails to fully act on the material, improving the loosening ability of semi-finished products such as tobacco shreds, leaves, and stems, avoiding repeated loosening and paddle operations, reducing breakage and waste, and improving product quality. Simultaneously, this application incorporates a buffer design for the main rake nails, enhancing operational safety. With the structure unchanged, if the materials stored in the storage tank change, only the auxiliary rake nails of different lengths need to be replaced, making it widely applicable.
