Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco machines, and particularly relates to a tobacco shredder and a knife door gap adjustment component thereof. Background Art

[0002] In the tobacco industry, the shredder is a key equipment in the production of shredded wire. The SQ34 shredder has a unique structure and a curved blade horizontal cutting method, which makes its shredding quality better than other models. Therefore, it has extremely high precision requirements for the gap between the lower knife door, that is, the distance between the blade and the lower knife door, which needs to be maintained at 0.2mm to 1mm. The traditional adjustment method is to use the following method in the prior art to adjust the gap between the shredder blade and the knife door. First, determine the position of the shredder blade. Paste cigarette paper in the middle and both ends of the blade with a thickness of the required gap between the blade and the knife door, evenly apply a small amount of ink at three locations corresponding to the knife door, and then turn the knife roller by hand to make the blade with cigarette paper pass through the knife door. If the ink is evenly applied to the cigarette paper, the gap is ideal, and the cigarette paper is cut off, indicating that the gap is too small; if there is no ink on the cigarette paper, it means that the gap is too large, and it is necessary to manually advance the knife to readjust the position. Secondly, determine the position of the grinding wheel. After determining the position of the blade, manually rotate the knife roller to shake the blade to the position of the grinding wheel, manually push the grinding wheel downward, so that the grinding wheel and the blade touch each other. At this time, the position of the grinding wheel is the standard position. Then, determine the position of other blades. Taking the grinding wheel as the reference, manually shake the other blades in turn until they touch the grinding wheel, and the position of all blades is determined. Finally, determine the position of the diamond. Taking the grinding wheel as the reference, adjust the diamond to touch the grinding wheel, and the position of the diamond is determined. After the positional relationship between the blade and the knife gate, the grinding wheel and the diamond, and the blade and the grinding wheel is determined, the value of the gap between the blade and the knife gate is also determined. When the gap distance between the blade and the knife gate meets the requirements of wire cutting, the adjustment process is completed. If it does not meet the requirements, the above method steps need to be repeated until the gap distance between the blade and the knife gate meets the requirements of wire cutting. When the tolerance is exceeded, fine-tune again based entirely on experience.

[0003] The above method uses a sticker method to adjust the knife door gap, but the slitting machine cannot be accurately adjusted immediately using the sticker method during the production process, that is, when it is running. It can only be temporarily adjusted based on operating experience, and the temporary adjustment of the knife door gap is inaccurate. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a tobacco cutter and a knife door gap adjustment component thereof, so as to solve the problem in the prior art that the knife door gap cannot be adjusted instantly and accurately by using a sticker method during the production process.

The following is a description of the embodiments of the present invention based on its overall structure.

[0024] Figure 1 This is a schematic diagram of the structure of the adjustment assembly provided by the utility model, see Figure 1 The adjustment assembly includes a mounting frame plate 1, a positioning pin 2 and a plurality of gaskets 3.

[0025] The mounting plate 1 is connected to the grinding wheel of the tobacco cutter, and the positioning pin 2 is connected to the mounting plate 1 through a connecting member 4, so that the positioning pin 2 is connected to the grinding wheel of the tobacco cutter.

[0026] The positioning pin 2 is connected to the mounting plate 1 through a connecting piece 4, and the mounting plate 1 is connected to a grinding wheel. A plurality of the gaskets 3 overlap each other, and the overlapping plurality of the gaskets 3 are arranged between the positioning pin 2 and the diamond. The protruding amount of the diamond is confirmed by the thickness of the gasket 3, and thus the knife gate clearance of the tobacco cutter is determined by the protruding amount of the diamond.

[0027] The adjustment assembly provided in the above embodiment, when adjusting the knife gate gap of the tobacco shredder, takes the grinding wheel as a reference, when the diamond does not touch the grinding wheel, that is, when the diamond does not scrape the positioning pin, first stack a gasket between the diamond and the positioning pin, and then calculate the distance between the diamond and the positioning pin by the thickness of the gasket, then adjust the diamond to touch the grinding wheel, the positioning pin scrapes the diamond, and then calculate the extension amount of the diamond, that is, the extension length of the diamond, to confirm the position of the diamond. During the operation of the shredder, the position of the diamond determines the position of the grinding wheel, and the position of the grinding wheel determines the length of the blade of the knife roller body, which also determines the gap between the blade and the knife. Therefore, the knife gate gap adjustment assembly provided by the utility model determines the positional relationship between the grinding wheel and the diamond by the extension length of the diamond, and finally can confirm the gap distance between the blade and the knife gate, thereby meeting the shredding requirements of the tobacco shredder.
