Technical Field

[0001] The present invention relates to a flipping device, in particular to a cigarette strip flipping device for a cigarette packing machine. Background Art

[0002] The YB95 cigarette packing machine completes the forming of the transparent wrapping for the strip package. For the strip of cigarettes with the transparent wrapping completed, the transparent drawstring laps all face downward. During the process of conveying the strip package to the downstream equipment, the drawstring lap rubs against the conveying channel, which will cause quality problems such as the drawstring of the strip package being curled up. At the same time, because the drawstring lap of the strip package contacts the conveying channel downward, the appearance inspection of the strip package above the inlet channel of the carton sealer cannot identify the drawstring defect. To avoid the occurrence of quality problems, it is very necessary to flip the strip of cigarettes with the transparent wrapping completed by 180°, so that the drawstring lap of the strip package faces upward. However, there is currently no structure on the equipment to flip the strip of cigarettes, and this problem needs to be solved urgently. Summary of the Invention

Detailed implementation manners

[0020] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and cannot be construed as a limitation to the present invention.

[0021] Embodiment of the present invention: As Figures 1-7 shown, a cigarette turning device for a cigarette packaging machine includes a cigarette output bottom plate 1 of the packaging machine and a cigarette turning panel 2. The cigarette turning panel 2 includes a horizontal section 21, an inclined section 22 and a supporting section 23. One end of the horizontal section 21 is connected to the cigarette output bottom plate 1 of the packaging machine, one end of the inclined section 22 is connected to the other end of the horizontal section 21, and the other end of the inclined section 22 is connected to the supporting section 23.

[0022] By providing the cigarette turning panel 2, when the cigarette 3 is transparently wrapped in the packaging machine and sent out through the cigarette output bottom plate 1 of the packaging machine, in order to prevent the cigarette 3 from skewing when moving on the cigarette output bottom plate 1 of the packaging machine, cigarette side baffles 11 are respectively provided on the left and right sides of the cigarette output bottom plate 1 of the packaging machine. Through the arrangement of the cigarette side baffles 11, it can be ensured that the cigarette 3 accurately moves onto the cigarette turning panel 2.

[0023] The cigarette 3 first moves horizontally on the horizontal section 21. When it moves to the position of the inclined section 22, it slides down along the inclined section 22 until it contacts the supporting section 23. At this time, the cigarette 3 is flipped under the push of the subsequent cigarettes and separated from the supporting section 23, and then falls onto the belt conveyor 7 located below the supporting section 23. When it falls onto the belt conveyor 7, the cigarette 3 has completed a 180° flip, making the lap joint of the strip package drawstring face upward, avoiding the lap joint friction phenomenon during the conveying process.

[0024] The cigarette turning panel 2 can be formed by stamping a whole metal plate or by welding three metal plates.

[0025] Specifically, the length a of the inclined section 23 is less than the width b of the cigarette strip 3, and the length c of the supporting section 23 is less than the height d of the cigarette strip 3.

[0026] Preferably in this embodiment, the length a of the inclined section 23 is two-thirds of the width b of the cigarette strip 3, and the length c of the supporting section 23 is two-thirds of the height d of the cigarette strip 3.

[0027] Through this size design, after the cigarette strip 3 contacts the supporting section 23, the upper end of the cigarette strip 3 tilts up, that is, a part of the cigarette strip 3 is higher than the horizontal section 21. The purpose of this design is to enable the cigarette strip 3 to be pushed by the subsequent cigarette strips. And by designing the length of the supporting section 23 to be two-thirds of the height of the cigarette strip 3, on the one hand, the supporting section 23 can effectively limit the position of the cigarette strip 3, and on the other hand, the cigarette strip can be better separated from the supporting section 23.

[0028] Further, the included angle e between the inclined section 23 and the horizontal section 21 is 105° - 140°, preferably 135°, and the supporting section 23 is perpendicular to the inclined section 22. Through the design of the 135° included angle, it is ensured that the cigarette strip 3 can slide smoothly.

[0029] In order to prevent the cigarette strip 3 from shifting and falling from the left and right sides of the horizontal section 21 when moving on the horizontal section 21, a cigarette strip retaining rod 4 is respectively installed on both sides of the horizontal section 21.

[0030] The structures of the two cigarette strip retaining rods 4 are completely the same. The cigarette strip retaining rod 4 includes a horizontal retaining rod 41, a first connecting screw rod 42, and an arc-shaped retaining rod 43. The arc-shaped retaining rod 43 is fixedly arranged at one end of the horizontal retaining rod 41. The arc-shaped retaining rod 43 is located above the inclined section 22. Two first connecting screw rods 42 are fixedly arranged on the horizontal retaining rod 41. The two first connecting screw rods 42 are perpendicular to the horizontal retaining rod 41. Two first mounting holes 44 are respectively opened on both sides of the horizontal section 21. The first connecting screw rod 42 is inserted into the first mounting hole 44 and fixed by a first locking nut 45.

[0031] The first mounting hole 44 preferably adopts a waist-shaped hole, so that the distance between the two cigarette strip retaining rods 4 can be adjusted according to requirements. When installing the cigarette strip retaining rod 4, the two first connecting screw rods 42 are passed through the two first mounting holes 44. There are two first locking nuts 45 on the first connecting screw rod 42. One first locking nut 45 is located above the horizontal section 21, and the other is located below the horizontal section 21. By adjusting the positions of the two first locking nuts 45, the height of the horizontal retaining rod 41 can be adjusted.

[0032] A smoke pressing plate 6 is also installed on the horizontal section 21. The width of the smoke pressing plate 6 is equal to the width of the horizontal section 21. Two second connecting screws 61 are fixed on both sides of the smoke pressing plate 6. The second connecting screws 61 are perpendicular to the smoke pressing plate 6. Two second mounting holes 63 are also provided on both sides of the horizontal section 21. The second connecting screws 61 are plugged into the second mounting holes 63 and fixed by second locking nuts 62.

[0033] The installation mode and height adjustment principle of the cigarette pressing plate 6 are the same as those of the cigarette bar 4. The cigarette pressing plate 6 is used to press the cigarette bar 3 to prevent the cigarette bar 3 from tilting when pushing the cigarette bar 3 in the tilted state.

[0034] Furthermore, two connecting plates 5 with through holes are fixedly provided at the bottom of the horizontal section 21 , and the two connecting plates 5 with through holes are fixedly connected to the cigarette strip output bottom plate 1 of the packaging machine by bolts.

[0035] The working principle of the present invention is as follows: after the cigarette strips 3 are transparently wrapped in the packaging machine, they are sent out through the cigarette strip output bottom plate 1 of the packaging machine. Through the setting of the two cigarette strip side baffles 11, the cigarette strips can be accurately moved to the cigarette strip flip panel 2.

[0036] When a cigarette rod 3 moves on the cigarette turning panel 2, it first moves horizontally along the horizontal section 21. Restricted by the cigarette rod blocking bars 4 on the left and right sides, the cigarette rod 3 does not tilt during movement. When the leading cigarette rod 3 reaches a certain position, it flips over and contacts the inclined section 22, sliding diagonally downward along the inclined section 22 until it contacts the supporting section 23. At this point, one end of the cigarette rod 3 rises and exceeds the top surface of the horizontal section 21.

[0037] As the subsequent cigarette strips 3 move, the second cigarette strip 3 pushes the first cigarette strip 3 to flip it over. When it flips to a certain angle, the cigarette strip 3 separates from the support section 23, flips 180 degrees and falls onto the belt conveyor 7. After the flip, the overlapping ends of the cigarette strips 3 face upwards and are sent to the downward moving process by the belt conveyor 7.

[0038] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
