Description

Technical Field

[0001] This utility model relates to the field of tobacco filter rod forming technology, specifically a material spraying device for forming tobacco filter rods. Background Technology

[0002] In the production process of tobacco filter rods, in order to improve the final functionality of the filter rods, it is usually necessary to spray the filament bundles with materials. The existing technology mainly involves material spraying systems.

[0003] However, most existing material spraying systems transport filament bundles via conveyor belts and spray materials onto the bundles during this process. This results in insufficient uniformity of material spraying. As the material accumulates on the surface of the filament bundles, the lower and bottom parts of the bundles cannot be fully mixed with the material, leading to low mixing efficiency between the filament bundles and the material.

[0004] Therefore, a material spraying device for forming tobacco filter rods is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a material spraying device for forming tobacco filter rods, so as to solve the problem of low mixing efficiency of filaments and materials mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material spraying device for forming tobacco filter rods, comprising a mounting component, a vibration component, and a spraying component;

[0029] Reference Figures 1-4 As shown, this utility model provides a technical solution for a material spraying device used in the molding of tobacco filter rods:

[0030] Reference Figure 1As shown, a material spraying device for forming tobacco filter rods includes a mounting assembly, a vibration assembly, and a spraying assembly. The mounting assembly includes a base plate 1 and a U-shaped side plate 11 disposed on the top edge of the base plate 1. A detachable insert plate 12 is disposed at the open end of the U-shaped side plate 11. The vibration assembly includes a base block 2 disposed at four inflection points at the bottom of the base plate 1. A top block 21 is slidably connected to the base block 2. Short shafts 13 are disposed at both ends of the left and right sides of the base plate 1. The short shafts 13 are rotatably connected to the adjacent top blocks 21. A horizontal connecting rod 3 is disposed between the two base blocks 2 on the left and right sides of the base plate 1. A support rod 31 is disposed on the top surface of the horizontal connecting rod 3. A rotating shaft 41 is rotatably connected between the two support rods 31. A motor 4 is connected to one end of the rotating shaft 41. A convex ring block 5 is sleeved on the rotating shaft 41. The spraying assembly includes a vertical connecting rod 32, a conveying rod 6, a nozzle 61, and a connecting pipe 62. The vertical connecting rod 32 connects the conveying rod 6 to the side of the base plate 1. The connecting pipe 62 is used to convey materials into the conveying rod 6. The conveying rod 6 is hollow inside. The nozzle 61 is located on the bottom side of the conveying rod 6.

[0031] Reference Figure 1 As shown, several nozzles 61 are provided, and these nozzles 61 are evenly spaced on the bottom side of the conveyor rod 6. It should be noted that there are two sets of spraying components, and the conveyor rod 6 is located on the top of the base plate 1. The specific number of spraying components depends on the need to spray the material evenly onto the top surface of the filament bundle on the top surface of the base plate 1; in this embodiment, there are two sets.

[0032] Reference Figure 3 As shown, in an optional embodiment, the open end of the U-shaped side plate 11 is provided with a groove 14, and the insert plate 12 is inserted into the groove 14 to close the open end of the U-shaped side plate 11.

[0033] Reference Figure 3 and Figure 4 As shown, a sleeve block 22 is fitted onto the top block 21, and a spring 23 is disposed between the sleeve block 22 and the bottom block 2. It should be noted that the spring 23 is fitted onto the top block 21, but the spring 23 is not in contact with the top block 21. (Refer to...) Figure 4 As shown, the four nested blocks 22 are located at the same position on the top block 21. (Refer to...) Figure 3 and Figure 4 As shown, the motor 4 is fixedly connected to the support rod 31, which is located in the middle of the horizontal connecting rod 3. It should be noted that the convex ring block 5 rotates with the rotating shaft 41, thereby intermittently lifting the base plate 1.

[0034] This device, through the setting of the vibration component, utilizes the rotation of the convex ring block 5 to intermittently lift the base plate 1, thereby causing the filament bundle on the top surface of the base plate 1 to vibrate up and down. When the material is sprayed onto the base plate 1 through the nozzle 61, the material can penetrate into the filament bundle more fully, greatly improving the mixing efficiency of the filament bundle and the material. This device also tilts the base plate 1 toward the opening end of the U-shaped side plate 11 by pressing the opening end of the base plate 1, thereby making the tilting of the filament bundle easier and faster, improving the efficiency of collecting the filament bundle. The structure is ingenious and simple, and is suitable for widespread application.

[0035] The working principle of this device is explained through its operation process: The operator pours the filament bundle onto the base plate 1 and supplies material, mostly granular material, into the conveying rod 6 through the connecting pipe 62. At this time, the motor 4 is started, and the rotation of the output end of the motor 4 will drive the rotating shaft 41 to start rotating, thereby causing the convex ring block 5 to start rotating. Due to the protrusion of the outer side of the convex ring block 5, it intermittently lifts the base plate 1, causing the filament bundle on the top surface of the base plate 1 to vibrate up and down under the action of gravity and inertia. The material in the conveying rod 6 is sprayed onto the filament bundle on the top surface of the base plate 1 through the nozzle 61. The material follows the vibration of the filament bundle on the top surface, preventing the material from accumulating on the top surface of the filament bundle. That is, under the action of its own gravity and inertia, it is easier to pass through the gaps in the filament bundle from the top surface, thereby more fully penetrating into the filament bundle and improving the mixing efficiency of the filament bundle and the material.

[0036] When it is necessary to pour out the filaments after the mixture, simply press the open end of the bottom plate 1 facing the U-shaped side plate 11. Since the short shaft 13 is rotatably connected to the top block 21, the bottom plate 1 will tilt towards the open end of the U-shaped side plate 11. Then, the worker can pull out the insert plate 12 from the groove 14, causing the filaments after the mixture on the top surface of the bottom plate 1 to slide down, which facilitates the collection of the filaments and improves the collection efficiency of the filaments.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
