[0022] The attached figure shows the preferred embodiment of the roller-type tobacco leaf non-grading table. The following is a more detailed description of this application in conjunction with the attached figure.

[0023] Depend on Figures 1 to 5 As shown, the roller-type tobacco leaf non-grading table includes a support table 1 and a rotating roller 2.

[0024] The support platform 1 serves as the basic load-bearing structure of the equipment and mainly includes a top frame 101, a guide box 102, a collection box 103, and support legs 104. These components work together to realize the functions of tobacco leaf conveying and impurity guidance and collection.

[0025] The top frame 101 adopts a rectangular ring-shaped frame design to provide stable installation support for the roller 2. Its rectangular structure is adapted to the tobacco leaf conveying path to ensure that the tobacco leaves do not deviate from the track during the conveying process.

[0026] The bottom surface of the feed box 102 is set as an inclined surface. The inclined structure uses gravity to guide impurities mixed in the tobacco leaves, such as broken leaves, dust, and small stones, to slide to the lower point. The top surface is open and fixedly connected to the top frame 101 to form the lower enclosure of the tobacco leaf conveying channel to prevent tobacco leaves and impurities from scattering.

[0027] The collection box 103 and the guide box 102 are connected at the lowest point of their bottom surfaces to collect falling impurities. In this embodiment, two structural forms are designed to adapt to different production scenarios: The first type: The lower end of the collection box 103 is open, which is suitable for scenarios where impurities do not require negative pressure to assist in collection. Impurities fall naturally into the collection box 103 through the inclined surface of the guide box 102, and can be cleaned manually or collected by covering with a cloth bag.

[0028] The second type: The lower end of the collection box 103 is closed, and the box body is connected to the connector 3. The connector 3 is connected to the external negative pressure suction system to enhance the impurity collection capacity and is suitable for the efficient removal of fine and light impurities.

[0029] Several support legs 4 are fixed below the material guide box 102 to ensure the overall stability of the support platform 1. The support legs 4 can be telescopic rods, and their height can be adjusted according to the on-site installation requirements to ensure that the equipment is placed horizontally.

[0030] Inside the top frame 101, several rotating rollers 2 are rotatably mounted via a rotating shaft 201. The rollers 2 are parallel to each other and spaced apart, and their rotation enables the smooth conveying of tobacco leaves. The spacing between the rollers 2 can be adjusted according to the particle size requirements of the tobacco leaf grading, ensuring that the tobacco leaves pass through smoothly while allowing impurities to fall from the gaps between the rollers into the feed box 102.

[0031] The negative pressure impurity removal auxiliary system is designed for the negative pressure collection box 103, and is equipped with a receiving box 4 and filter plate 5 to improve impurity collection efficiency and maintenance convenience. The receiving box 4 is detachably connected to the collection box 103. It is inserted into the box body through a pull-out hole on the side wall of the collection box 103 and is located above the connector 3 to directly receive falling impurities. The outer wall of the receiving box 4 has a fixed handle 401 for easy removal and cleaning by the operator; several air vents 402 are opened on the bottom to ensure normal airflow of negative pressure; and a ring-shaped support frame 403 is protruding in the middle of the interior for placing the filter plate 5.

[0032] The filter plate 5 is detachably mounted on the support frame 403, and its filter hole inner diameter is larger than the air outlet 402 on the bottom surface of the impurity collection box 4. The filter plate 5 can prevent impurities from being sucked into the negative pressure system, while ensuring smooth airflow and avoiding the negative pressure effect being affected by impurities clogging the system.

[0033] Several scrapers 6 are fixed inside the top frame 101. The scrapers 6 are arranged one-to-one with the rotating rollers 2, and the top of the scraper 6 abuts against the lower half of the circumferential surface of the rotating roller 2. During the rotation of the rotating roller 2, the scrapers 6 can clean the residual tobacco leaf fragments and impurities on the surface of the rotating roller 2 in real time, so as to avoid the residual materials from affecting the tobacco leaf conveying and grading accuracy, and ensure the continuous and stable operation of the rotating roller 2.

[0034] After the equipment is started, the rotating roller 2 rotates at a constant speed. The rotating roller 2 can be rotated by manually pushing the tobacco leaves to drive the rotating roller 2 to rotate, or by having gears fixed on the outside of the rotating shaft 201. All gears are connected to a synchronous belt, and a servo motor that drives the synchronous belt to rotate is fixed on the outside of the support platform 1, so as to realize the automatic rotation of the rotating roller 2.

[0035] The tobacco leaves to be processed are evenly spread above the rotating roller 2, and the tobacco leaves are conveyed forward as the roller 2 rotates. During the conveying process, impurities in the tobacco leaves fall from the gap between the rollers 2 to the guide box 102 below under the action of gravity. The inclined bottom surface of the guide box 102 guides the impurities to slide to the lowest point and finally fall into the collection box 103.

[0036] The open-type collection box 103 directly collects impurities and requires regular manual cleaning. The negative pressure collection box 103 generates airflow through the negative pressure suction system connected to the connector 3, which accelerates the falling of impurities. The impurities are collected by the impurity collection box 4, and the filter plate 5 blocks the impurities from entering the negative pressure pipeline. The airflow is discharged through the air outlet 402 of the filter plate 5 and the impurity collection box 4.

[0037] As the roller 2 rotates, the scraper 6 continuously contacts the circumferential surface of the roller 2, cleaning any remaining tobacco leaves and impurities from the roller 2 surface to ensure cleanliness and prevent material adhesion that could affect the conveying effect. The cleaned tobacco leaves continue to be conveyed with the roller 2 to the next grading process, achieving continuous operation of impurity removal and grading pretreatment.

[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
