Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cigarette product quality detection, and particularly relates to a cut tobacco separating device for cigarette moisture detection. BACKGROUND

[0002] In the tobacco production detection process, the moisture of the finished cigarette rolled is needed to be determined, and the cut tobacco in the cigarette is needed to be stripped according to the national standard and the industry standard. In the long-term actual detection process, the cut tobacco separation work in the cigarette has the largest work intensity, consumes the longest time, and it is also difficult to guarantee the completeness of the cut tobacco in the separated cigarette, and the moisture change caused by long-time operation brings great uncertainty to the accuracy of the detection data.

[0003] Nowadays, there are various cut tobacco separating devices, which save a lot of detection cost compared with manual detection. For example, the Chinese invention patent with the announcement number CN106840804A discloses a cigarette clamping device and a cut tobacco separating equipment using the cigarette clamping device, which comprises an outer sleeve, an elastic tube with an inner diameter smaller than the diameter of the cigarette arranged in the outer sleeve, an annular chamber formed between the elastic tube and the outer sleeve, a gas hole provided on the outer sleeve and communicating with the annular chamber, and the elastic tube has an expansion position which expands along the radial direction and adheres to the outer sleeve when the gas hole communicates with the negative pressure source or the vacuum pumping mechanism, so that the cigarette can enter the elastic tube, and a contraction position which contracts along the radial direction and clamps the cigarette when the gas hole is disconnected from the negative pressure source or the vacuum pumping mechanism. However, the invention needs to set an additional negative pressure source or vacuum pumping mechanism to control the contraction of the elastic tube, and the additional negative pressure source or vacuum pumping mechanism needs to be additionally set with a corresponding intelligent switch structure, which increases the manufacturing cost and wastes resources.

The first spring 242 is in a compressed state in a normal state, so that the connecting block 241 of the arc-shaped gear rack 24 abuts against one end of the sliding groove 13.

[0028] The main body 1 is provided with a frame body 6, the frame body 6 comprises a plurality of annular rings 61, a plurality of support bars 62 are connected between adjacent annular rings 61, the frame body 6 is divided into a first blocking layer 63 and a second blocking layer 64, the first blocking layer 63 is provided with a first blocking device 71, and the second blocking layer 64 is provided with a second blocking device 72.

In use, the driving device drives the main body 1 to rotate, so that the clamping device 2 and the limiting device 3 move, when the rotating plate 22 rotates, the clamping block 21 moves to the center, the clamping device 2 gradually clamps, and the limiting device 3 gradually closes.

[0031] When one end of the arc-shaped gear rack 24 of the limiting device 3 abuts against the limiting baffle 714, because the elasticity of the first spring 242 is smaller than that of the second spring 712, the arc-shaped gear rack 24 is blocked, so that the first spring 242 continues to be compressed, after the arc-shaped gear rack 24 is blocked, the rotating plate 22 can be driven to rotate, so that the limiting device 3 gradually closes until completely closes, after completely closes, the arc-shaped gear rack 24 will move with the main body 1, so that the second spring 712 is compressed, the flue 11 moves to the cigarette entering position, and the stepping motor 4 stops rotating, in this process, the clamping device 2 is always in an open state.

Then, the main body 1 is continuously rotated by the stepping motor 4, the arc-shaped rack 24 of the clamping device 2 is twisted by the elastic force of the first spring 242 and the second spring 712, the limiting baffle 714 is twisted by the torsional spring, the limiting baffle 714 is rotated into the slot 715, the blocking of the arc-shaped rack 24 of the clamping device 2 is released, the arc-shaped rack 24 is bounced back, the clamping device 2 is released, and the cigarette slides out of the flue 11.

[0035] The upper and lower ends of the main body 1 are provided with cover bodies 8 on the mounting seat 12, the cover of the cover body 8 is attached to the arc-shaped rack 24 to prevent the arc-shaped rack 24 from jumping.

[0039] When the device is used, the driving device drives the main body 1 to rotate, so that the clamping device 2 and the limiting device 3 move. When one end of the arc-shaped rack 24 of the limiting device 3 abuts against the limiting baffle 714, the arc-shaped rack 24 is blocked because the elasticity of the first spring 242 is smaller than that of the second spring 712. The first spring 242 is continuously compressed, and after the arc-shaped rack 24 is blocked, the rotating plate 22 can be driven to rotate, so that the limiting device 3 is gradually closed until it is completely closed.
