Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a chopper disc pressing device for a cigarette making machine. Background Art

[0002] The leveler uses a chopper disc to trim the tobacco bundle on the suction ribbon, and its executive components are a chopper disc and a brush wheel. In order to prevent the tobacco bundle from being offset due to lateral force during leveling, a double chopper disc is symmetrically set based on the center of the tobacco bundle. The chopper is a pair of disc-shaped blades located below the suction ribbon. They are symmetrically arranged based on the center line of the tobacco bundle and driven by the main transmission system to rotate in opposite directions at the same speed (rotation directions are opposite, and the theoretical outer circle tangent point linear speed is equal) to trim the tobacco bundle passing above it. There are six equally divided grooves on the chopper. When leveling, the groove part allows more tobacco to pass. The action position of the chopper disc groove is relatively synchronized with the cutting position of the cutter cutting the tobacco rod, so that the cutter cuts in the middle of the tobacco rod where the chopper disc groove acts, forming a tight head cigarette.

[0003] After being cut by the leveler device, the tobacco bundle that meets the process requirements is sent to the top of the cigarette paper. The negative pressure disappears, and the scraper scrapes the tobacco on the smoking belt. The tobacco bundle and the cigarette paper are driven by the cloth belt into the pipette channel and rolled into cigarette strips. The chopping blade groove on the leveler is an elliptical groove formed by stamping. Since the groove processing technology is stamping, the upper part is large and the lower part is small, and the groove depth is inconsistent. The cutter head can only cut at the axis of the ellipse to make the cigarette head tight. If the cutter head and the chopping knife are misaligned at the same time or the chopping knife blade is damaged, the number of empty loose cigarettes will increase. The chopping knife disk will jump ≤0.05mm during operation. When large stems and impurities in the tobacco pass through instantly, it is easy to cause the chopping knife disk to jump more than this data, which will cause the weight of a single cigarette to be unstable, and further affect the various physical indicators of the cigarette, such as standard deviation, suction resistance, and end drop.

[0004] To ensure good guiding and shearing effects, the brush wheel and the chopping knife disc and the two chopping knife discs should be as close as possible. In order for the leveler to work normally and not interfere with each other during movement, the gap between the rear chopping knife disc and the brush wheel is required to be 0.1mm. The front chopping knife disc is 0.1mm higher than the rear chopping knife disc, and the gap between the two chopping knife discs is 0.1mm. The precision of the gap can obtain the ideal average weight index of cigarettes. Since the chopping knife disc has a shearing function, the thickness of the chopping knife disc blade is generally 0.02MM. When the chopping knife disc has abnormal fluctuations or jumps at high speed, it is very easy to cause the chopping knife disc shearing function to fail, resulting in equipment failure and quality risks.

[0005] Therefore, it is urgent to design a riving cutter disc clamping device to ensure the transmission accuracy and quality of the riving cutter disc during high-speed operation and maintenance. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a cigarette making machine chopper disc clamping device, which can effectively improve the high-speed operation accuracy of the chopper disc when trimming tobacco bundles, extend the service life of the chopper disc, and ensure the high quality of product process quality.

[0007] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0008] A chopper disc clamping device for a cigarette making machine comprises a device body which is annular and provided with a plurality of clamping disc holes which are connected to chopper disc holes via chopper disc fixing screws.

[0009] Preferably, in the above technical solution, the positions of the plurality of clamping disc holes and the plurality of riving knife disc holes correspond one to one.

[0010] Preferably, in the above technical solution, the plurality of compression disc holes are distributed at equal intervals along the circumference of the device body.

[0020] 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.

[0021] like Figure 1 As shown, a chopper disc clamping device for a cigarette making machine comprises a device body 1, which is annular and has a plurality of clamping disc holes 2, and the clamping disc holes 2 and the chopper disc holes 3 are fixed by chopper disc fixing screws.

[0022] Furthermore, the positions of the plurality of clamping disc holes 2 correspond to the positions of the chopper disc holes one by one. The plurality of clamping disc holes 2 are evenly spaced along the circumference of the device body 1. Preferably, the number of the clamping disc holes 2 is four, the diameter thereof is 5 mm, and the hole spacing between two adjacent clamping disc holes 2 is 64 mm.

[0023] Furthermore, the material of the device body 1 is temperable stainless steel. The outer diameter of the annular device body 1 is 75 mm, the inner diameter is 26 mm, and the thickness is 2 mm.

[0026] After the clamping device was improved, the replacement cycle of the cutter disc was extended from the original 15 days to 40 days. It not only reduced the vibration frequency of the cutter disc during high-speed rotation, but also further ensured the shearing accuracy of the cutter disc during high-speed operation, improved the equipment operation efficiency, and further guaranteed the quality of the product.
