Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cigarette production equipment, and more specifically to a multi-stage cleaning device for circular knives of cigarette making machines. Background Art
[0002] The principle of secondary cutting of cigarette making machine is as follows: after double-length filter cigarettes are conveyed to the secondary cutting wheel, they enter the cutting guide rail. Under the joint action of the secondary cutting wheel, cutting guide rail and cutter, the double-length cigarettes are cut into normal cigarettes.
[0003] Because medium-sized cigarette filter rods are relatively hard, to ensure cutting quality, the original stainless steel blade + grinding wheel grinding method was eliminated and replaced directly with alloy blades. Furthermore, because the gluing ability of medium-sized cigarette tipping paper is weaker than that of regular cigarettes, the glue is not easily absorbed by the tipping paper during cutting. As the equipment continues to operate, excess glue adheres to the two end faces of the cutter. This glue accumulation makes the cutter rotation inflexible and damaged, increasing the frequency of cleaning by repairmen and blade changes by operators. Furthermore, the increased glue accumulation on the cutter leads to quality issues with the cut of the cigarettes.
[0004] Therefore, there is an urgent need for a multi-stage cleaning device for the circular knife of a cigarette making machine. Utility Model Content

[0026] like Figure 1-Figure 3As shown, the multi-speed cleaning device for the circular knife of the cigarette making machine provided in this embodiment includes: a base 6, two rocker arms 3 are provided on the base 6, a scraper 1 is installed on each rocker arm 3, a spring 7 is provided between each rocker arm 3 and the outer side of the side wall of the base 6, and a plurality of holes 8 are respectively opened on each rocker arm 3, and the spring 7 corresponding to each rocker arm 3 is respectively installed in one of the holes 8; the circular knife of the cigarette making machine is clamped by the two scrapers 1 to achieve the cleaning of the circular knife of the cigarette making machine.
[0027] The base 6 is mounted in the original grinding wheel seat position, and the scraper 1 is mounted on the top of the rocker 3. Made of hard alloy, the scraper 1 is highly wear-resistant. Each scraper 1 is shaped like a frustum, with the base being the working edge. There are three working edges in total. When worn, the scraper 1 can be rotated and replaced with another edge for continued use. The bases of the two scrapers 1 clamp the circular knives of the cigarette making machine, cleaning them as they rotate.
[0028] Furthermore, each of the scrapers 1 is connected to the rocker arm 3 via a corresponding first pin shaft 2 , and each of the rocker arms 3 is symmetrically arranged at both ends of the outer side of one side wall of the base 6 .
[0029] Furthermore, the bottom end of each of the swing arms 3 is mounted on the outer bottom end of the side wall of the base 6 via a second pin shaft 5 , and each of the swing arms 3 can rotate around the corresponding second pin shaft 5 .
[0030] Furthermore, both ends of each spring 7 are respectively mounted on the spring seat 4. The number of holes 8 on each rocker arm 3 is 3-6, and each hole is evenly distributed on the corresponding rocker arm 3, and each spring 7 is installed in the hole 8 with the same serial number. For example, both springs 7 are installed in the fourth hole 8 from the top. In one embodiment of the present invention, the number of holes 8 on each rocker arm 3 is 4. It should be noted that the present invention does not specifically limit the number and distribution of the holes 8 and the serial number of the installation of the springs 7 in the holes 8.
[0031] During operation, before use, the clamping force of the scraper 1 must first be pre-adjusted. By flexibly switching between different hole positions 8 on the rocker arm 3, the elongation of the spring 7 is changed, and multi-level adjustment of the clamping force of the spring 7 is achieved, so that the cigarette machine circular knife can be adjusted to the optimal cleaning state; the two scrapers 1 generate a clamping force under the tension of the spring 7, and the cigarette machine circular knife is clamped by the bottom edges of the two scrapers 1. When the cigarette machine circular knife rotates, the cigarette machine circular knife can be cleaned.
[0032] The embodiment of the utility model provides a multi-speed cleaning device for the circular knife of a cigarette making machine. By flexibly switching between different hole positions, the elongation of the spring is changed. The spring force is adjusted in multiple gears to change the clamping force, thereby realizing multi-speed adjustment of the spring clamping force and adjusting the circular knife to the optimal cleaning state. The frequency of cleaning the knife gap of the cutting drum is increased from 2-3 days / time to 2 weeks / time, and the frequency of replacing the cutter by the operator is increased from 1-2 days / time to 2 weeks / time, which effectively improves the efficiency of the equipment, reduces the labor intensity of the operator and repairman, and effectively ensures the quality of the cigarette cut. The multi-speed adjustment is adopted to ensure the cleaning degree while maximizing the service life of the circular knife. The compatibility is high and it is applicable to different machine models.
