Description

Technical Field

[0002] Tillage and re-drying of tobacco leaves is the first step in cigarette production and a crucial process for removing foreign matter from tobacco. During this process, tobacco leaves mainly contain a variety of foreign matter, including hemp rope, plastic film, sand, hair, binding straps, insect cocoons, aluminum foil, metal, wood blocks, rubber, and paper strips. These foreign matter are not only diverse but also vary considerably in shape and properties.

[0003] Currently, traditional methods for removing impurities from tobacco leaves mainly include manual sorting and simple mechanical screening. While manual sorting can remove impurities relatively accurately, it is labor-intensive, inefficient, and easily affected by human factors, leading to inconsistent impurity removal results. Simple mechanical screening methods, such as vibrating screens, can improve impurity removal efficiency to some extent, but they are difficult to effectively separate impurities such as hemp rope, plastic film, hair, binding straps, and insect cocoons, resulting in limited impurity removal effects. Therefore, this application proposes an impurity removal device with an impurity transfer roller. Utility Model Content

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] This utility model discloses a debris removal device with a debris transfer roller.

[0033] According to the appendix Figure 1-2 As shown, it includes a carrying unit 1, which is installed above the tobacco conveyor belt. The carrying unit 1 is equipped with a driving unit 2, and the driving unit 2 is connected to an electrostatic cleaning cloth 3. The driving unit 2 can drive the electrostatic cleaning cloth 3 to perform cyclical movement. The bottom part of the electrostatic cleaning cloth 3 is in contact with the tobacco leaves on the tobacco conveyor belt and is used to hook up the debris on the tobacco leaves.

[0034] The carrying unit 1 is equipped with a debris transfer unit 4, a tapping unit 5, and a debris collection box 6. The debris transfer unit 4 can transfer debris from the electrostatic cleaning cloth 3. The tapping unit 5 taps the debris transferred by the debris transfer unit 4, causing the debris to fall into the debris collection box 6.

[0035] Through the coordinated operation of each unit, efficient impurity removal from tobacco leaves is achieved. The electrostatic impurity removal cloth 3, driven by the drive unit 2, circulates and hooks onto impurities on the tobacco leaves; the impurity transfer unit 4 transfers the impurities from the electrostatic impurity removal cloth 3 to itself; and the beating unit 5 beats the transferred impurities, causing them to fall into the impurity collection box 6. The entire device has a reasonable structure and complete functions, effectively improving the efficiency and quality of impurity removal from tobacco leaves.

[0036] Specifically disclosed, the carrier unit 1 includes:

[0037] Box 11;

[0038] The support frame 12 is installed at the bottom of the box 11 by means of a screw rod;

[0039] The mounting clamp 13 is fixedly installed on the outside of the tobacco conveyor belt by bolts, and the mounting clamp 13 is fixedly installed on the bottom of the support frame 12;

[0040] Positioning wheels 14 are symmetrically arranged below the housing 11, and the two positioning wheels 14 are in contact with the inner ring surface of the electrostatic cleaning cloth 3.

[0041] The housing 11 serves as the main structure of the supporting unit 1, used to install and accommodate other components. The support frame 12 is mounted to the bottom of the housing 11 via screws, providing support and fixation. The mounting clamp 13 is bolted to the outside of the tobacco conveyor belt and fixed to the bottom of the support frame 12, used to fix the entire device to the tobacco conveyor belt. Positioning wheels 14 are symmetrically arranged below the housing 11, fitting against the inner surface of the electrostatic cleaning cloth 3, serving to position and guide the movement of the electrostatic cleaning cloth 3.

[0042] Specifically disclosed, drive unit 2 includes:

[0043] The drive motor 21 is fixedly installed on the outside of the housing 11;

[0044] The drive sprocket 22 is rotatably mounted inside the housing 11 via the drive shaft, and the output end of the drive motor 21 is connected to the drive shaft for transmission.

[0045] The passive sprocket 23 is mounted inside the housing 11 and rotates via a passive shaft.

[0046] The plastic mesh chain 24 has its transmission mechanism located between the driving sprocket 22 and the driven sprocket 23.

[0047] Furthermore, the electrostatic cleaning cloth 3 is attached to the outer side of the plastic mesh chain 24.

[0048] The drive motor 21 is fixedly installed on the outside of the housing 11, providing power to the entire drive unit. The drive sprocket 22 is rotatably mounted inside the housing 11 via a drive shaft. The output end of the drive motor 21 is connected to the drive shaft, transmitting the power of the drive motor 21 to the plastic mesh chain 24. The driven sprocket 23 is rotatably mounted inside the housing 11 via a driven shaft, cooperating with the drive sprocket 22 to drive the plastic mesh chain 24. The plastic mesh chain 24 is driven between the drive sprocket 22 and the driven sprocket 23. The electrostatic cleaning cloth 3 is in contact with the outside of the plastic mesh chain 24. When the plastic mesh chain 24 is driven, it drags the electrostatic cleaning cloth 3, thus realizing the cyclical movement of the electrostatic cleaning cloth 3.

[0049] Specifically disclosed, the debris transfer unit 4 includes:

[0050] The transfer electric roller 41 is wrapped with a fleece cloth on its outer side, and the transfer electric roller 41 is located on the side of the electrostatic cleaning fleece cloth 3.

[0051] Cylinder 42 is installed in housing 11, and the output end of cylinder 42 is connected to transfer electric roller 41.

[0052] Furthermore, a bracket 43 is installed on the outside of the transfer electric roller 41, and a sliding groove is provided in the housing 11. The end of the bracket 43 is slidably disposed in the sliding groove, and the output end of the cylinder 42 is fixedly connected to the bracket 43.

[0053] The transfer electric roller 41 has a fleece wrapped around its outer side and is positioned to the side of the electrostatic cleaning fleece 3. Through contact with the electrostatic cleaning fleece 3, it transfers debris onto its own fleece. A cylinder 42 is installed in the housing 11, and its output end is connected to the transfer electric roller 41 to drive its movement, facilitating better contact and separation from the electrostatic cleaning fleece 3. A bracket 43 is installed on the outside of the transfer electric roller 41. A groove is provided in the housing 11, and the end of the bracket 43 is slidably positioned within the groove. The output end of the cylinder 42 is fixedly connected to the bracket 43, enabling the transfer electric roller 41 to move stably under the drive of the cylinder 42.

[0054] Specifically, the tapping unit 5 includes:

[0055] The electric tapping roller 51 is rotatably mounted in the housing 11 and is positioned obliquely above the transfer electric roller 41.

[0056] A flexible slapping plate 52 is installed on the outside of the slapping electric roller 51.

[0057] The electric tapping roller 51 is rotatably mounted in the housing 11 and positioned diagonally above the transfer electric roller 41. Its rotation drives the flexible tapping plate 52 to tap the debris on the transfer electric roller 41. The flexible tapping plate 52 is installed on the outside of the electric tapping roller 51 to tap the debris and cause it to fall off.

[0058] Furthermore, the debris collection box 6 is installed at the bottom of the housing 11 and below the transfer electric roller 41 and the beater electric roller 51, so as to facilitate the collection of debris falling from the transfer electric roller 41.

[0059] When the drive motor 21 is powered on, it starts to run. The rotational motion of the drive motor 21 transmits power through its output shaft, driving the connected drive sprocket 22 to rotate. As a key starting component for power transmission, the drive sprocket 22 performs stable and continuous circular motion around its own axis under the drive of the drive motor 21.

[0060] As the drive sprocket 22 rotates, the plastic mesh chain 24 also begins to move. During this movement, the plastic mesh chain 24 drives the driven sprocket 23 to move accordingly. Driven by the plastic mesh chain 24, the driven sprocket 23 also rotates around its own axis, ensuring the smooth and stable operation of the entire transmission system and laying the foundation for subsequent impurity removal.

[0061] Simultaneously, the electrostatic cleaning cloth 3, attached to the plastic mesh chain 24, also enters its working state. The running direction of the plastic mesh chain 24 is consistent with the material feeding direction. This design allows for sufficient and appropriate contact between the material and the electrostatic cleaning cloth 3, facilitating the adhesion of impurities. Furthermore, the running speed of the plastic mesh chain 24 and the electrostatic cleaning cloth 3 is faster than the material feeding speed. Due to this speed difference, when the material moves slowly on the feeding device, the relatively faster movement of the electrostatic cleaning cloth 3 makes it easier for impurities on the material feeding device to adhere to the electrostatic cleaning cloth 3.

[0062] As the electrostatic cleaning cloth 3 moves continuously, the debris caught on it also moves along with it, gradually moving into the working area of ​​the transfer electric roller 41. The transfer electric roller 41 is also wrapped with cloth of the same material as the electrostatic cleaning cloth 3. This design aims to better transfer and collect debris and reduce the rate of incorrect rejection of tobacco leaves. Furthermore, the operating speed of the transfer electric roller 41 is intentionally set to be faster than that of the plastic mesh chain 24. Thus, when the electrostatic cleaning cloth 3 carrying debris comes into contact with the transfer electric roller 41, the faster linear speed of the transfer electric roller 41 allows the debris on the cloth to be more easily caught on it, further realizing the transfer of debris from the cloth 3 to the roller 41. This improves the efficiency and effectiveness of the cleaning process while also reducing the rate of incorrect rejection of tobacco leaves.

[0063] After the entire impurity removal process has been ongoing for a period of time, the transfer electric roller 41 will retreat from the electrostatic impurity removal cloth 3 and return to a position close to the tapping electric roller 51 according to a preset program. When the transfer electric roller 41 reaches the position of the tapping electric roller 51, the tapping electric roller 51 begins to rotate in the opposite direction. During the reversal process, the impurities accumulated on the transfer electric roller 41 will move relative to the tapping electric roller 51. Due to its fixed position and specific shape, the tapping electric roller 51 can effectively remove the impurities accumulated on the transfer electric roller 41, causing the impurities to detach from the transfer electric roller 41 and fall into the specially designed impurity collection box 6. When the impurity collection box 6 has collected a certain amount of impurities, it is pulled out and poured into the designated impurity placement area, thus completing the entire impurity removal process. This ensures the purity of the tobacco material in subsequent processing stages and ensures that the quality of tobacco products is not affected by impurities.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
