Description

Technical Field

[0001] The utility model relates to cigarette filter rod manufacturing equipment, and more specifically to an ALM module particle dropping device. Background Art

[0002] The particle adding module is mainly used for the manufacture of special filter rods, that is, adding activated carbon, kudzu root and other particles to the tow belt to produce material rods with specific functions. When the particle adding module is running, the particles slide from the end of the conveyor belt to the moving tow belt, are wrapped and carried by the tow belt into the molding process and are rolled into filter rods. In actual production, the particles fall vertically on the surface of the tow belt in a "waterfall" shape. The vertical distance between the particle conveyor belt and the tow belt is about 300mm. The greater the distance between the particles and the tow belt, the greater the gravitational potential energy of the particles, and the greater the impact caused by falling on the tow belt. Under the impact of the particles, the moving tow belt will rebound, resulting in unstable operation of the tow belt and ejecting the particles in different directions, resulting in less particles wrapped by the tow belt and entering the molding process, and then producing material rods with low particle content. In addition, the large impact of the particles on the tow belt will directly penetrate the tow belt, causing damage to the mesh structure of the tow belt and affecting the filtering performance of the material rod.

[0003] Therefore, in view of the large vertical distance between the particles and the filament belt when adding particles to the ALM module, the impact of the particles on the filament belt will cause unstable operation of the filament belt and damage the filament mesh structure. It is necessary to design a dropping device to buffer the gravitational potential energy of the particles, so that the particles can fall smoothly onto the moving filament belt, reduce particle rebound, and ensure that the particle content of the material rod is qualified and stable.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] according to Figures 1 to 3 As shown, the utility model provides an ALM module particle dropping device, including a buffer mechanism 1, a hopper 2, an opener and a molding machine;

[0033] The opening machine is used to open the filter rod tow band 5, and the forming machine is used to roll the filter rod tow band 5 wrapped with particles 4 into a filter rod;

[0034] The hopper 2 is arranged above the filter rod tow belt 5 between the opener and the forming machine, and is used for feeding and conveying the particles 4; a conveyor 3 is also arranged below the hopper 2, and the conveying direction of the conveyor 3 is opposite to the moving direction of the filter rod tow belt 5;

[0035] The buffer mechanism 1 is arranged obliquely between the discharge port of the conveyor 3 and the filter rod tow belt 5 so that the particles 4 can slide into the loosened filter rod tow belt 5 .

[0036] The buffer mechanism 1 in the utility model mainly functions to buffer the gravitational potential energy generated when the particles 4 fall, so as to prevent the particles 4 from directly falling onto the moving filter rod filament belt 5, causing impact on the filter rod filament belt 5, resulting in unstable operation, large-scale shaking, and ejecting more particles 4. At the same time, it also prevents the mesh structure of the filter rod filament belt 5 from being damaged, thereby affecting the filtering performance of the material rod and the smoking taste of the cigarette.

[0037] Furthermore, the buffer mechanism 1 includes a bottom plate 11, a bracket 17, and two sets of baffle plates 12; one side of the bottom plate 11 is connected to the bracket 17, the bracket 17 is fixed to the fuselage wall plate, and the two sets of baffle plates 12 are arranged on the upper surface of the bottom plate 11 and are respectively located on both sides of the discharge port of the conveyor 3. The function of the baffle plates 12 is to limit the sliding trajectory of the particles 4 to prevent the particles 4 from being too dispersed and not conducive to addition.

[0038] Furthermore, two groups of fixed supports 13 are provided on the bottom plate 11, and the two groups of fixed supports 13 are respectively arranged on the outside of the two groups of baffle plates 12. The fixed supports 13 are provided with a rotatably connected adjusting screw 14, and the baffle plates 12 are provided with a nut 15 that cooperates with the adjusting screw 14, so that the spacing between the two groups of baffle plates 12 can be adjusted by adjusting the screw 14. A spring 19 is also provided between the fixed supports 13 and the baffle plates 12, and the spring 19 is sleeved on the adjusting screw 14. The position of the baffle plates 12 can be adjusted according to the width of the particles 4 and the width of the tow band. Specifically, the width adjustment of the baffle plate 12 is completed by the adjustment screw 14, the nut 15 and the spring 19. When the adjustment screw 14 is rotated clockwise, the spring 19 is tightened, the distance between the two baffle plates 12 becomes larger, and the sliding width of the particles 4 becomes wider. When the adjustment screw 14 is rotated counterclockwise, the spring 19 is loosened to push the baffle plate 12 to move, the distance between the two baffle plates 12 becomes smaller, and the sliding width of the particles 4 becomes narrower.

[0039] Furthermore, a guide rod 16 is further provided on one side of the two groups of baffle plates 12 facing the fixed support 13, and a guide hole for sliding connection of the guide rod 16 is provided on the fixed support 13. The function of the guide rod 16 is to support the baffle plates 12 and to assist in adjusting the width of the baffle plates 12.

[0040] Furthermore, at least two waist-shaped holes 18 are provided at the connection between the bracket 17 and the bottom plate 11, and the length direction of the waist-shaped holes 18 is perpendicular to the baffle plate 12, so as to adjust the distance between the bottom plate 11 and the fuselage wall plate through the waist-shaped holes 18. The position of the buffer mechanism 1 can be adjusted according to production requirements, the bracket 17 is fixed to the fuselage wall plate by the existing threaded holes, and the buffer mechanism 1 is installed as a whole at an angle between the conveyor 3 and the filter rod tow belt 5, ensuring that the particles 4 completely fall on the bottom plate 11 of the buffer mechanism 1 and are just distributed between the two baffle plates 12.

[0041] Furthermore, a support roller 6 is provided between the opening machine and the forming machine. The support roller 6 is located below the filter rod filament band 5 to support the filter rod filament band 5 .

[0042] Furthermore, a collecting bucket is provided at the bottom of the filter rod tow belt 5, and the remaining particles 4 fall into the collecting bucket and are recycled.

[0043] During the production of the equipment, the particles 4 dropped from the hopper 2 are conveyed to the end of the conveyor 3, and the particles 4 fall onto the bottom plate 11 of the buffer mechanism 1. The vertical distance between the drop point of the particles 4 and the end of the conveyor 3 and the vertical distance between the end of the bottom plate 11 and the filter rod tow belt 5 are small, and the gravitational potential energy of the particles 4 is small. The particles 4 slide down in a "slide" manner and finally fall onto the moving filter rod tow belt 5. The gravitational potential energy of the particles 4 falling to the buffer mechanism 1 and the particles 4 falling from the buffer mechanism 1 to the filter rod tow belt 5 are both small. The particles 4 will not rebound significantly on the bottom plate 11, nor will they have a significant impact on the filter rod tow belt 5, and will even damage the mesh structure of the filter rod tow belt 5. By using the buffer mechanism 1, the large gravitational potential energy and impact of the particles 4 are eliminated, thereby stabilizing the running trajectory of the filter rod filament belt 5, avoiding the filter rod filament belt 5 from shaking and ejecting a large number of particles 4, and ensuring that the mesh structure of the filter rod filament belt 5 is intact, thereby ensuring the content of the material rod particles 4, the filtering effect of the filter rod and the smoking taste of the produced cigarettes.
