[0038] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will refer to Figures 1 to 4 An embodiment of a tobacco baking machine of the present invention is further described.

[0039] Figure 1 It is a structural schematic diagram of a tobacco baking machine of the present invention, comprising Figure 1 It can be seen that the tobacco drying machine described in the present invention includes a frame 1 and a conveyor chain plate 2 for conveying tobacco. The conveyor chain plate 2 is installed on the frame 1, and the conveyor chain plate 2 is connected end to end and is annularly sleeved on the frame 1, including a top surface for carrying the tobacco to be dried, and also includes two side surfaces and a bottom surface opposite to the top surface. Since the conveyor chain plate 2 is in the process of conveying tobacco, the fine and broken tobacco is easily adhered to the conveyor chain plate 2 or easily enters the gap of the conveyor chain plate 2. In order to facilitate the cleaning of the conveyor chain plate 2, the present invention is as follows Figure 1 As shown, a cleaning device for cleaning the conveying chain plate 2 is provided, and the cleaning device is detachably and fixedly mounted on the frame 1 .

[0040] In one embodiment of the present invention, the cleaning device includes a cleaning brush 3, and the cleaning brush 3 abuts against the conveying chain plate 2. Specifically, the cleaning brush 3 includes bristles and a mounting portion, and the mounting portion is detachably mounted on the frame 1. The bristles abut against the conveying chain plate 2, and are used to clean the tobacco debris on the conveying chain plate 2. In order to facilitate the installation of the cleaning brush 3, the present invention preferably has a connecting plate 4 fixedly provided on the frame 1, and a mounting hole 5 is provided on the connecting plate 4, and the mounting portion of the cleaning brush 3 is fixedly installed on the connecting plate 4 by bolts. The cleaning brush 3 can be provided in two pieces, and the two cleaning brushes 3 are symmetrically distributed on the two sides of the conveying chain plate 2. During the conveying process of the conveying chain plate 2, the conveying chain plate 2 and the cleaning brush 3 move relative to each other, and the cleaning brush 3 completes the cleaning of the conveying chain plate 2.

[0041] Since the bristles of the cleaning brush 3 will be worn after working for a long time, the bristles will become shorter, which affects the cleaning of the conveyor chain plate 2 by the cleaning brush 3. Figure 2 and Figure 3 As shown, a further embodiment of the present invention is that the tension of the cleaning brush 3 when cleaning the conveying chain plate 2 is adjustable, and the specific design is as follows: the conveying chain plate 2 is arranged in an inverted trapezoidal shape, the top and bottom surfaces are both horizontal, and the two side surfaces are arranged in an inclined surface. The mounting holes 5 on the connecting plate 4 can be arranged in a plurality in the vertical direction, and the cleaning brush 3 is installed at the mounting holes 5 with different heights, so that the height of the cleaning brush 3 changes, so that the cleaning brush 3 is away from or close to the angle between the side surface of the conveying chain plate 3 and the vertical direction, and the tension adjustment of the cleaning brush 3 when cleaning the conveying chain plate 2 is completed. The mounting hole 5 can also be designed as a through hole, and the through hole is designed as a rectangular through hole or a runway-shaped through hole, and the length of the through hole extends in the vertical direction, so that the installation position of the cleaning brush 3 can move up and down along the length direction of the mounting hole 5.

[0042] A further embodiment of the present invention is: the cleaning device also includes a brush roller, the brush roller abuts against the conveying chain plate 2, specifically, the brush roller includes a roller shaft and bristles arranged on the roller shaft, the bristles on the roller shaft abut against the conveying chain plate 2, and the rotation of the roller shaft drives the bristles on the roller shaft to clean the conveying chain plate 2. The roller shaft is rotatably mounted on the frame 1 through a rolling bearing. The brush roller includes an upper brush roller 6 and a lower brush roller 7, wherein the upper brush roller 6 is located on the side of the conveying chain plate 2 facing away from the cleaning brush 3, so that the upper brush roller 6 and the cleaning brush 3 are respectively located on the inner and outer sides of the conveying chain plate 2, and both sides of the conveying chain plate 2 are cleaned, thereby improving the cleaning effect. The upper brush roller 6 can be installed on the side of the conveyor chain plate 2 or on the bottom of the conveyor chain plate 2; and the lower brush roller 7 is installed on the bottom of the conveyor chain plate 2 and is located below the conveyor chain plate 2. When the bottom of the conveyor chain plate 2 tends to sag due to gravity, the lower brush roller 7 supports the conveyor chain plate 2 during the cleaning process to prevent the conveyor chain plate 2 from drooping and dragging on the ground.

[0043] Furthermore, two upper brush rollers 6 and two lower brush rollers 7 are provided, and the two upper brush rollers 6 are symmetrically distributed on the left and right sides of the conveying chain plate 2, so as to achieve a better cleaning degree; the two lower brush rollers 7 are both located below the conveying chain plate 2, so as to provide a more balanced support to the conveying chain plate 2.

[0044] During the process of conveying the baked tobacco, the contact temperature of the conveying chain plate 2 is relatively high. Therefore, the temperature of the conveying chain plate 2 will also be high. Therefore, the cleaning brush 3 and the brush roller are in contact with the conveying chain plate 2, that is, the bristles of the cleaning brush 3 and the brush roller are made of PP material. PP material has the characteristics of high temperature resistance and wear resistance, which can increase the service life of the cleaning brush 3 and the brush roller.

[0045] In addition, since the transmission chain plate 2 and the frame 1 are mostly designed with metal materials, if the transmission chain plate 2 and the frame 1 are directly in contact with each other during transmission, the mutual friction between the metals is relatively large, which will affect the transmission efficiency. Figure 4 As shown, a "["-shaped connecting pipe 8 is fixedly connected to the frame 1, and two connecting pipes 8 are provided. The two connecting pipes 8 are provided on the left and right sides of the conveying chain plate 2 along the width direction of the conveying chain plate 2, and the connecting pipe 8 is only located on the top surface of the conveying chain plate 2. The connecting pipe 8 can be designed as an integral piece to be consistent with the length direction of the top surface of the conveying chain plate 2, or multiple connecting pipes can be provided along the conveying direction of the conveying chain plate 2, and installed on the frame 1 at intervals to abut against the conveying chain plate 2; a nylon strip 9 is sleeved at the bottom end of the connecting pipe 8, and the conveying chain plate 2 is mounted on the nylon strip 9. During the conveying process of the conveying chain plate 2, the conveying chain plate 2 abuts and rubs against the nylon strip 9. The nylon strip 9 is a non-metallic material. When it abuts and rubs against the metal conveying chain plate 2, the friction force is smaller than the friction between metals, thereby reducing the friction of the conveying chain plate 2 and increasing the service life of the conveying chain plate 2.

[0046] Furthermore, in order to prevent tobacco from leaking out through the gap between the conveying chain plate 2 and the connecting tube 8 during the conveying process, a further embodiment of the present invention is that a sealing block 10 is provided on the conveying chain plate 2, and the sealing block 10 is pasted on the side of the conveying chain plate 2 facing away from the nylon strip 9. The shape of the sealing block 10 matches the conveying chain plate 2, and the sealing block 10 abuts against the connecting tube 8. The sealing block 10 blocks the gap between the connecting tube 8 and the conveying chain plate 2, thereby preventing tobacco from falling. The sealing block 10 is also made of nylon material to reduce the relative friction between the sealing block 10 and the connecting tube 8.

[0047] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, any improvements and modifications made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
