Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser punching equipment, in particular to a smoke and dust adsorption mechanism for laser punching of tipping paper. Background Art
[0002] Laser punching of tipping paper is a technology that uses high-precision laser technology to process micropores on the surface of tipping paper (special packaging paper commonly used for products such as cigarette filters). The laser beam instantly vaporizes the material at high temperature to form tiny holes. It has the characteristics of uniform pore size, no mechanical contact, and high efficiency. It is mainly used to adjust air permeability, improve combustion performance or meet specific functional requirements. It is widely used in the tobacco industry to improve product quality and meet environmental protection standards.
[0003] The specification of Chinese utility model patent CN214721566U discloses a new laser punching device for producing environmentally friendly tipping paper, including a laser punching mechanism, a paper tape conveying mechanism, and a dust collection and waste discharge mechanism. The dust collection and waste discharge mechanism includes a rotating crawler, a dust collection box, a vacuum cleaner, and a collection box. The vacuum cleaner box is inserted into the cavity of the rotating crawler, and the vacuum cleaner box is connected to the vacuum cleaner. The laser punching mechanism performs laser punching on the tipping paper tape laid on the rotating crawler. The dust collection and waste discharge mechanism collects smoke and paper scraps generated by the laser punching. The smoke generated by the laser punching is sucked into the vacuum cleaner through the rotating crawler and the dust collection box in turn, and the paper scraps generated by the laser punching are transported into the collection box through the rotating crawler.
[0004] In the above patents and prior art, smoke and dust need to be filtered through a filter element. When the filter element is used for a long time, its permeability will decrease. In order to avoid the influence of smoke and dust, the filter element needs to be replaced regularly. However, the filter element needs to be stopped for operation when replacing, which is not only inconvenient, but also affects the efficiency of laser drilling. Therefore, we propose a smoke and dust adsorption mechanism for laser drilling of tipping paper. Utility Model Content

[0028] The following will be combined with the attached Figures 1 to 6 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] The utility model provides a smoke adsorption mechanism for laser punching of tipping paper through improvement, such as Figure 1 - Figure 6As shown, it includes an adsorption component 1, which includes a bellows 101, a fan 102 is connected to the side wall of the bellows 101, a filter cartridge 103 is connected to the fan 102, and a sealing cover 104 is threadedly connected to both ends of the filter cartridge 103, a secondary pipe 105 and a suction pipe 106 are connected to the filter cartridge 103, the secondary pipe 105 is connected to the suction pipe 106 through a branch pipe 108, and the branch pipe 108 is connected to a smoking hood 107 at one end away from the filter cartridge 103, a secondary filter element 109 is fixedly connected inside the secondary pipe 105, a wind speed sensor 110 is plugged into the secondary pipe 105, a plurality of filter components 2 are slidably connected inside the filter cartridge 103, a limit component 3 is fixedly connected to the side wall of the filter cartridge 103, and an electromagnet 5 electrically connected to the wind speed sensor 110 is fixedly connected to the upper sealing cover 104.
[0030] In this embodiment: the smoke hood 107 can be connected to the laser head. When the laser head is moving and punching, the smoke generated can be absorbed by the smoke hood 107. When the fan 102 is started, the bellows 101 extracts air from the lower side of the butt paper. After being filtered by the filter component 2, the drawn gas is ejected from the smoke hood 107 and blows air to the butt paper to form a circulating wind, thereby achieving the upward blowing and downward suction of the butt paper and improving the smoke and dust collection effect.
[0031] In the above embodiment, in order to achieve the purpose of automatic replacement when the permeability of the main filter element 203 decreases, the following method can be adopted:
[0032] The filter assembly 2 includes a magnet ring block 201 magnetically connected to the electromagnet 5, a sealing cover 202 is fixedly connected to the lower side wall of the magnet ring block 201, a main filter element 203 is fixedly connected inside the sealing cover 202, a connecting plate 204 is fixedly connected to the magnet ring block 201, two magnetic sliders 205 are slidably connected to the upper side wall of the connecting plate 204, the upper ends of the two magnetic sliders 205 are fixedly connected to inclined plates, and the two inclined plates can hook the pull ring 209 when they are against each other, a fixed plate 206 is fixedly connected at the center of the connecting plate 204, a spring 207 is fixedly connected between the two magnetic sliders 205 and the fixed plate 206, a connecting rope 208 is fixedly connected to the lower end of the main filter element 203, and a pull ring 209 is fixedly connected to the lower end of the connecting rope 208.
[0033] In a preferred embodiment, when the permeability of the main filter element 203 decreases, the main filter element 203 generates an upward force under the blowing force of the fan 102. When this force is greater than the force of the limit assembly 3 on the filter assembly 2, the main filter element 203 will move upward for a distance. At this time, the auxiliary pipe 105 is partially connected to the filter cartridge 103. At this time, part of the smoke will be filtered by the auxiliary filter element 109 and discharged from the smoke hood 107. At the same time, the wind speed inside the auxiliary pipe 105 will be detected by the microcomputer in conjunction with the wind speed sensor 110, so that the microcomputer can start the electromagnet 5 through the controller. The electromagnet 5 attracts the magnet ring block 201 through magnetic attraction, driving the filter assembly 2 to move upward. At the same time, this filter assembly 2 is connected through the connecting rope 208. And the pull ring 209 pulls the new filter component 2 upward. When the magnet ring block 201 in the new filter component 2 contacts the limit component 3, the magnetic slider 205 will separate under the suction of the magnetic block 4, so that the pull ring 209 is separated from the new filter component 2. At this time, the new filter component 2 will close the auxiliary pipe 105 again, so that the new filter component 2 can filter the smoke. After the work is completed, the staff can unscrew the sealing cover 104 on the upper side and then take out the blocked filter component 2. In addition, the staff can also regularly unscrew the sealing cover 104 on the lower side and put in the new filter component 2. At the same time, it should be noted that the two magnetic sliders 205 in the new filter component 2 should hook the pull ring 209.
[0034] refer to Figure 4 and Figure 6 In a preferred embodiment, the limiting assembly 3 includes a mounting shell 301 fixedly connected to the filter cartridge 103, two mounting plates 302 are fixedly connected inside the left and right sides of the mounting shell 301, a stop plate 303 is rotatably connected between the two mounting plates 302, a torsion spring 304 is fixedly connected between the stop plate 303 and the mounting plate 302, two magnetic blocks 4 are fixedly connected to the side wall of the mounting shell 301, and the magnetic blocks 4 are magnetically connected to the magnetic slider 205.
[0035] This embodiment: In the initial state, the push plate 303, under the action of the torsion spring 304, limits the filter assembly 2 to prevent the filter assembly 2 from moving upward under the wind force. When the permeability of the filter assembly 2 drops to a certain level, the wind resistance of the filter assembly 2 increases. At this time, the force of the filter assembly 2 moving upward under the action of the wind increases. When this force is greater than the downward force applied to the filter assembly 2 by the push plate 303 under the action of the torsion spring 304, the push plate 303 will flip upward, thereby releasing the restriction on the filter assembly 2.
[0036] Among them, the fan 102, wind speed sensor 110 and electromagnet 5 are all existing technologies, and their structural principles will not be repeated. At the same time, the device also includes a power supply, a switch, a controller, a power supply cable and other devices, which are not the main technologies and will not be described in detail.
[0037] Working principle: When in use, first, the staff starts the fan 102, and then the bellows 101 extracts air from the lower side of the tipping paper. After being filtered by the filter assembly 2, the extracted gas is ejected from the smoking hood 107 and blows air to the tipping paper, forming a circulating wind, achieving the upward blowing and downward suction of the tipping paper, and improving the collection effect of smoke and dust;
[0038] When the permeability of the filter assembly 2 drops to a certain level, the wind resistance of the filter assembly 2 becomes larger. At this time, the upward force of the filter assembly 2 under the action of the wind becomes larger. When this force is greater than the downward force applied to the filter assembly 2 by the torsion spring 304 by the plate 303, the plate 303 will flip upward, thereby releasing the restriction on the filter assembly 2, and the main filter element 203 will move upward for a distance. At this time, the auxiliary pipe 105 is partially connected to the filter cartridge 103. At this time, part of the smoke will be filtered by the auxiliary filter element 109 and discharged from the smoke hood 107. At the same time, the microcomputer and the wind speed sensor 110 will detect The wind speed inside the auxiliary pipe 105 enables the microcomputer to start the electromagnet 5 through the controller. The electromagnet 5 attracts the magnet ring block 201 through magnetic attraction, driving the filter component 2 to move upward. At the same time, the filter component 2 pulls the new filter component 2 upward through the connecting rope 208 and the pull ring 209. When the magnet ring block 201 in the new filter component 2 contacts the limit component 3, the magnetic slider 205 will separate under the attraction of the magnetic block 4, so that the pull ring 209 is separated from the new filter component 2. At this time, the new filter component 2 will close the auxiliary pipe 105 again, so that the new filter component 2 can filter the smoke.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
