Technical Field
[0001] The utility model relates to the technical field of cigarette conveying equipment, in particular to an automatic cigarette guiding auxiliary device for a cigarette quantitative conveyor. Background Art
[0002] The production and manufacturing equipment of special-shaped packaging cigarettes is the development direction of cigarette machine equipment in the future. A few years ago, the special-shaped packaging production model still relied on traditional simple manual labor as the only labor force. When the existing cigarettes were packaged in special shapes, the cigarettes needed to be manually transferred and clamped. This process is very easy to cause the cigarette body to be damaged by squeezing and wrinkling, and the manual stacking of cigarettes during filling is prone to messy cigarettes. In order to ensure the quality of cigarette products, improve the neatness of cigarette stacking, and also to ensure that the efficiency of cigarette production and manufacturing is at a high level, cigarette turning equipment based on cigarette quantitative conveyors has emerged. The equipment adopts dynamic turning over free feeding, that is, under the condition of ensuring the normal operation of the equipment, the filling process is completed by the weight of the cigarettes themselves. Taking the cigarette quantitative conveyor as an example, during the filling process, the cigarette tray of the cigarette turning over equipment is in an inverted state and fits with the guide plates on both sides of the unloading box to prevent cigarettes from leaking out of the gap between the guide plates and the turning over. However, when the filling is completed, in order to ensure that there are enough cigarettes in the discharge box before the next filling process occurs, the height of the cigarette stacking will usually be higher than the height of the guide plates on both sides of the discharge box, resulting in the cigarettes being unable to enter the discharge box without being restricted. It is easy for the cigarettes to leak directly out of the cigarette quantitative conveyor from above the guide plates on both sides. At the same time, the cigarette turning equipment will cause the cigarette tray to rotate in the opposite direction during the process of returning to the waiting state, resulting in messy stacking of cigarettes on both sides, which will cause a large number of cigarettes to be damaged and wasted.

DETAILED DESCRIPTION
[0016] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0017] See also Figures 1 to 3 The present embodiment discloses an automatic smoke guiding auxiliary device for a cigarette quantitative conveyor. The cigarette quantitative conveyor includes a feed box. Feed box guide plates 1 are respectively provided on both sides of the feed box. The gap between the two feed box guide plates 1 forms a feed channel with a contracted bottom. The automatic smoke guiding auxiliary device includes two groups of smoke guiding auxiliary components 2 respectively installed on the top of the two feed box guide plates 1.
[0018] Each group of smoke guide auxiliary components 2 includes a limit block 3 and a fixed block 4 arranged vertically, the fixed block 4 extends vertically and the bottom end of the fixed block 4 is fixed to the top of the guide plate 1 of the discharge box, the limit block 3 is elastically supported on the top of the fixed block 4 by an elastic component, and in a natural state, under the elastic force of the elastic component, the limit block 3 is in the upper limit position and a gap is left between the fixed block 4; the limit block 3 moves downward and contacts the fixed block 4 when pressurized; a bearing 5 is installed on the top of the limit block 3, and the sleeve is installed on the limit block 3 through a mounting shaft 13 extending in the left and right directions, and the highest point of the bearing 5 is higher than the top surface of the limit block 3.
[0019] Three guide shafts extending vertically downward are fixedly provided at the bottom of the limit block 3, and the three guide shafts are respectively two end guide shafts 6 and one middle guide shaft 7. Three slideways slidably matched with the three guide shafts are provided at the top of the fixed block 4, and the three slideways are respectively two end slideways and one middle slideway. Limiting convex rings are provided at the bottom ends of the two end guide shafts 6, and retaining rings are provided on the inner side walls of the two end slides. The retaining rings and the limiting convex rings are resisted against each other to limit the upper limit position of the end guide shafts 6; the elastic component is a compression spring 8, and the compression spring 8 is sleeved on the upper section of the middle guide shaft 7, and the upper and lower ends of the compression spring 8 are elastically pressed against the top of the fixed block 4 and the bottom of the limit block 3 respectively.
[0020] Two positioning rods 9 are provided at the bottom of the limiting block 3 near the inner side, and two positioning grooves 10 are opened inside the fixing block 4. The positioning rods 9 and the positioning grooves 10 extend vertically, and the two positioning rods 9 are slidably matched with the two positioning grooves 10 respectively.
[0021] The top surface of the limit block 3 is composed of two front and rear working surfaces. The rear working surface is a horizontal working surface 11, and the front working surface is an inclined working surface 12 with the front end tilted downward. There is an arc transition between the front and rear working surfaces. A groove is opened on the top surface of the limit block 3 at the intersection of the front and rear working surfaces, and the bearing 5 is placed in the groove.
[0022] The working process of the automatic smoke guiding auxiliary device of the cigarette quantitative conveyor provided in this embodiment is as follows:
[0023] When the cigarette quantitative conveyor performs the filling action, the cigarette tray begins to flip downward, and the two sides of the cigarette tray preferentially contact the inclined working surface 12 of the bearing 5 and the limit block 3. As the cigarette tray continues to flip, the bearing 5 begins to rotate, and the two sides of the cigarette tray gradually approach the horizontal working surface 11 of the limit block 3. At this time, the limit block 3 is subjected to oblique downward pressure. Under the guidance of the three guide shafts and three slideways and the guidance of the two positioning rods 9 and two positioning grooves 10, the limit block 3 moves downward in the vertical direction, continuously compressing the compression spring 8. Until the cigarette tray is flipped over, the two sides of the cigarette tray fit with the horizontal working surface 11 of the limit block 3, and the limit block 3 contacts the fixed block 4. At this time, the limit block 3 is completely in the downward pressure state, and the filling operation can be carried out smoothly. The cigarettes are stacked neatly by their own gravity to avoid side leakage or disorder during filling.
[0024] When the filling operation is completed, the cigarette tray rotates in the opposite direction to reset, and the two side surfaces of the cigarette tray gradually separate from the horizontal working surface 11 of the limit block 3. Since the compression spring 8 converts the elastic potential energy into kinetic energy, the limit block 3 is lifted upward and reset by the upward force, and the bearing 5 still starts to slide close to the two side surfaces of the cigarette tray. As the cigarette tray continues to flip, the limit block 3 continues to rise, and the two side surfaces of the cigarette tray contact the inclined working surface 12 of the limit block 3. When the cigarette tray is completely reset, the cigarette tray is separated from the limit block 3, and the limit block 3 is lifted to the upper limit position. At this time, the limit block 3 is in the highest smoke blocking position to prevent the stacked cigarettes from leaking out.
[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
