The included angle between the two loosening roller groups refers to the region close to the inner corner of the L between the leftmost horizontally arranged loosening roller and the lowest vertically arranged loosening roller, and the large tobacco sheet that slips in the tailing stage will inevitably stay in this region due to the characteristics of the loosening mechanism.

[0027] In fact, the six horizontally arranged loosening rollers and the three vertically arranged loosening rollers can be set to different rotating speeds, so that the material at the included angle is better squeezed and sheared by the loosening rollers with different rotating speeds.

[0028] In the embodiment, the linkage mechanism 13 comprises a connecting rod 131 and a mounting frame 132, one end of the connecting rod 131 is flexibly connected with the upper part of the trigger swing plate 12, and the other end is hingedly connected with the middle part of the mounting frame 132; in the embodiment, one end of the mounting frame 132 is connected with a second rotating shaft 133, and is swingably connected in the machine body 1 through the second rotating shaft 133, and the other end of the mounting frame 132 is rotatably connected with the pressure roller 14; specifically, the second rotating shaft 133 is rotatably connected with the machine body 1, one end of the mounting frame 132 is rotatably connected with the second rotating shaft 133, and the other end is mounted with the pressure roller 14; the mounting frame 132 comprises two mounting side frames and a cross rod for connecting the two mounting side frames, and the mounting frame 132 is driven by the trigger swing plate 12 through the connecting rod 131 to swing the cross rod around the second rotating shaft 133.

[0029] In the embodiment, in order to reduce the risk of torsional deformation of the whole trigger swing plate 12 due to uneven stress, the reset elastic member 15 is a tension spring, the number of the tension spring is three, and the tension spring is evenly distributed on the upper end of the trigger swing plate 12, one end of the tension spring is connected with the upper end of the trigger swing plate 12, and the other end of the tension spring is connected with the support; when the trigger swing plate 12 is in the vertical state, the tension spring is just in the initial state, and in fact, the tension spring can also provide elastic force or tension to balance the weight of the trigger swing plate 12, the linkage mechanism 13 and the pressure roller 14.

[0030] In the embodiment, the upper end of the trigger swing plate 12 is provided with a limiting block 16 away from one side of the support 11, when the trigger swing plate 12 is in the vertical state, there is a gap between the upper end of the trigger swing plate 12 and the limiting block 16, when the trigger swing plate 12 is in the limit swing state, the upper end of the trigger swing plate 12 abuts against the limiting block 16; when the material feeding amount is particularly large, the upper end of the trigger swing plate 12 abuts against the limiting block 16, the trigger swing plate 12 plays the role of a material scraper, so that the material entering the loosening machine remains constant and no longer continues to increase, effectively ensuring the loosening effect of the loosening mechanism and reducing other faults caused by overload operation.

[0031] In the embodiment, the lower end of the trigger swing plate 12 is rotatably connected with a roller, the freely rotatable roller first contacts the material, which can reduce the hard scraping of the material by the plate edge and reduce the material crushing.

[0032] In the embodiment, the surface of the pressure roller 14 is provided with a convex ridge structure, the convex surface abuts against the large tobacco sheet slipping in the tail stage to assist the two adjacent loosening rollers at the corner to forcibly loosen.

[0033] In the embodiment, the two ends of each loosening roller are movably sleeved with a conical frustum-shaped cover 17, the conical frustum-shaped cover 17 is fixedly mounted on the machine body 1, and the conical frustum-shaped cover 17 can prevent the tobacco sheet from being clamped into the gap between the end surface of the loosening roller and the machine body, further reducing the residues that need to be manually cleaned by the workers.

[0034] The working principle of the utility model is as follows:

[0035] The tobacco sheet feeding conveyor of the utility model is used, and the baled tobacco sheet opened by the bale turning machine is conveyed from the feeding belt to the sheet loosening machine, the baled tobacco sheet is transmitted and scattered on the horizontally arranged loosening roller, until the vertically arranged loosening roller on the other side of the machine body, the tobacco sheet is extruded and sheared between the adjacent loosening rollers, and the loosening is completed in cooperation with the rake nails on the loosening roller, and the loosened tobacco sheet falls on the discharge belt on the bottom of the loosening mechanism, enters the silo, and is conveyed to the rear-end process through the lifting belt.

[0036] In this process, when the material conveying is sufficient, the continuous and stable tobacco sheet with a certain height continuously pushes the trigger swing plate 12, overcomes the tension of the tension spring, and makes the trigger swing plate 12 rotate clockwise and keep the trigger state, at this time, the material pressing roller 14 is lifted to a sufficient height, and the loosening mechanism normally operates.

[0037] When the material conveying approaches the end, only the last one or several large tail sheets that are not fully loosened continuously slip at the included angle between the horizontally arranged and vertically arranged loosening rollers, at this time, since there is not enough material to push the trigger swing plate 12, the tension spring drives the trigger swing plate 12 to reset counterclockwise, at this time, the material pressing roller 14 is lowered and presses on the large tail sheet that is slipping on the loosening mechanism, and assists the two adjacent loosening rollers at the included angle to forcibly loosen. It should be noted that the size of the pressing force can be adjusted by adjusting the length of the tension spring and is affected by the size of the tail sheet.

[0038] When the tail sheet is loosened and passes through the loosening mechanism, the tension spring continues to act to keep the whole linkage mechanism in static balance, and the trigger swing plate 12 keeps the vertical state until the front end of the next batch of material flow reaches to continuously apply the pressure, and the material pressing roller 14 again restores the normal working state of lifting.

[0039] The above embodiments are only used to illustrate the technical scheme of the utility model and not to limit it, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical scheme of the utility model, and all should be covered in the scope of the claims of the utility model. The technical, shape and structure parts not described in detail in the utility model are all known technologies.
