[0032] like Figure 1 As shown, in some embodiments of the tobacco conveyor provided by the utility model, the tobacco conveyor includes a conveying body 1, a conveyor belt 2, a guide wheel 3 and a tensioning device 4, the conveyor belt 2 is installed on the conveying body 1, the conveyor belt 2 is configured to move relative to the conveying body 1, the guide wheel 3 is installed on the conveying body 1, the guide wheel 3 is configured to guide the movement of the conveyor belt 2, the tensioning device 4 is arranged on the conveying body 1, and the tensioning device 4 is configured to adjust the position of the guide wheel 3 relative to the conveying body 1 to adjust the tension of the conveyor belt 2.

[0033] In the above embodiment, by providing the guide wheel 3, the conveyor belt 2 can be guided to move, thereby improving the accuracy of the movement route of the conveyor belt 2 and improving the conveying speed; by providing the tensioning device 4, the position of the guide wheel 3 relative to the conveying body 1 can be adjusted, thereby adjusting the tensioning force of the conveyor belt 2, thereby improving the safety and reliability of the use of the conveyor belt 2, and also preventing the shape of the tobacco on the conveyor belt 2 from being affected, causing the tobacco to accumulate, clump or fall, and affecting the conveying quantity and quality, etc., due to the tensioning force of the conveyor belt 2 being too large or too small.

[0034] like Figure 1As shown, the tobacco conveyor is provided with a plurality of guide wheels 3, and the conveyor belt 2 is wound around the plurality of guide wheels 3 to achieve multiple turns. By adjusting the position of one or more guide wheels 3 relative to the conveyor body 1, the tension of the conveyor belt 2 can be adjusted.

[0035] In some embodiments, the conveyor belt 2 is sucked by negative pressure so that the tobacco shreds are adsorbed on the conveyor belt 2 .

[0036] In some embodiments, the conveyor belt 2 is provided with through holes, and a fan is provided under the conveyor belt 2 , so that the tobacco shreds are adsorbed on the conveyor belt 2 through the suction effect of the fan.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments, the tensioning device 4 includes a driving member 41 and a mounting frame 42, the driving member 41 is arranged on the conveying body 1, the guide wheel 3 is installed on the mounting frame 42, the mounting frame 42 is connected to the driving member 41, and the driving member 41 drives the mounting frame 42 to move relative to the conveying body 1.

[0038] By providing the driving member 41 , the mounting frame 42 can be driven to move relative to the conveying body 1 , and then the mounting frame 42 drives the guide wheel 3 to move relative to the conveying body 1 , thereby adjusting the tension of the conveyor belt 2 .

[0039] In some embodiments, the tobacco conveyor further includes a dust cover 43 , and the driving member 41 is disposed inside the dust cover 43 .

[0040] By providing the dust cover 43 and arranging the driving member 41 inside the dust cover 43 , the driving member 41 can be effectively protected to prevent tobacco and dust from entering the driving member 41 and affecting the normal operation of the driving member 41 .

[0041] After the driving member 41 is damaged, the tension of the conveyor belt 2 cannot be adjusted, which may cause the conveyor belt 2 to slip or break, affecting the transportation of tobacco. Therefore, by providing the dust cover 43, the service life of the driving member 41 can be increased, the tensioning effect of the conveyor belt 2 can be ensured, and the replacement frequency of the driving member 41 can be reduced, saving manpower and improving the transportation efficiency.

[0042] In some embodiments, the tobacco conveyor further comprises a mounting plate 44 , which is mounted on the conveying body 1 , and the dust cover 43 and the guide wheel 3 are respectively arranged on both sides of the mounting plate 44 .

[0043] The mounting plate 44 can be used to support the dust cover 43. The dust cover 43 and the mounting plate 44 are combined to form a substantially closed space, which effectively improves the protection effect of the driving member 41.

[0044] The guide wheel 3 is installed on the side of the mounting plate 44 away from the dust cover 43 , which can optimize the structural layout and facilitate the winding of the conveyor belt 2 .

[0045] The mounting plate 44 may be provided with a mounting hole, and the driving member 41 and the mounting frame 42 are drivenly connected via the mounting hole.

[0046] In some embodiments, the driving member 41 includes a precision slide cylinder.

[0047] The volume of the precision slide cylinder is relatively small, and compared with a mechanical cylinder, it can effectively reduce the space occupied by the driving component 41 and improve the compactness of the structural arrangement.

[0048] The HLH series precision slide cylinder can be selected, which is cheap and has high reliability.

[0049] In some embodiments, the tobacco conveyor further includes a spacer block 45 , which is connected between the driving member 41 and the mounting frame 42 .

[0050] By providing the spacer block 45 , the distance between the driving member 41 and the mounting bracket 42 can be adjusted, thereby adjusting the relative position of the guide wheel 3 on the conveying body 1 , thereby facilitating the arrangement of the guide wheel 3 and the conveying belt 2 .

[0051] The number and thickness of the spacers 45 can be selected as required.

[0052] like Figure 3 As shown, in some embodiments, the mounting frame 42 includes a connecting portion and a mounting portion, the connecting portion is drivingly connected to the driving member 41, the guide wheel 3 is mounted on the mounting portion, and the connecting portion and the mounting portion are integrally formed.

[0053] By arranging the connection part and the mounting part to be integrally formed, the assembly steps of the mounting frame 42 can be reduced, thereby improving the assembly efficiency of the tensioning device 4.

[0054] In some embodiments, the connecting portion is perpendicular to the mounting portion.

[0055] By arranging the connecting portion and the mounting portion to be vertical, the mounting portion can be extended in a direction perpendicular to the mounting plate 44 , and then the guide wheel 3 can be installed on the side of the mounting portion, making it convenient for the conveyor belt 2 to be wound around the guide wheel 3 .

[0056] In some embodiments, the mounting portion decreases in size in a direction away from the connecting portion.

[0057] By setting the size of the mounting portion to decrease in a direction away from the connecting portion, the space occupied by the mounting portion can be reduced, thereby avoiding interference between the mounting portion and other components on the conveying body 1.

[0058] In some embodiments, the size of the mounting portion first remains constant and then gradually decreases in a direction away from the connecting portion.

[0059] The following is combined with Figures 1 to 3 The structure and working process of an embodiment of the tobacco conveyor provided by the utility model are described as follows:

[0060] like Figure 1 As shown, the tobacco conveyor includes a conveying body 1 and a conveying belt 2, a guide wheel 3 and a tensioning device 4 arranged on the conveying body 1.

The mounting frame 42 is located on the side of the mounting plate 44 away from the dust cover 43. Each driving member 41 is correspondingly provided with a pad 45 and a mounting frame 42. Two guide wheels 3 are installed on each mounting frame 42. The two guide wheels 3 are arranged at intervals in the vertical direction.

[0064] The spacer block 45 is in the shape of a rectangular parallelepiped. The mounting plate 44 is a flat plate.

[0065] The driving part 41 adopts HLH precision slide cylinder, which adopts micro-circulating ball linear guide rail and cylinder integrated design, the sealing rod has a small contact area with the outside world, and the dustproof function is better. Moreover, this type of cylinder has excellent straightness and non-rotational accuracy, and is more suitable for use in precision assembly occasions.

[0066] The mounting frame 42 adopts an integrated bracket, which can reduce the assembly process and facilitate quick installation.
