Description

Collecting rolls and filter rod forming machines for filter rod forming machines

technical field

The invention relates to a filter rod forming machine, in particular to a collection roller used in the filter rod forming machine and the filter rod forming machine.

Background technique

With the State Tobacco Administration's proposal of "upper cigarettes" and the continuous improvement of cigarette product quality requirements, filter rod production, an important process in cigarette manufacturing, has higher and higher requirements for its various quality indicators. The physical indicators of the filter rod mainly include weight, circumference, roundness, length, suction resistance, etc. Among them, the suction resistance and weight of the filter rod directly affect the next coiling process and are important quality indicators.

KDF4 filter rod forming machine consists of 4 parts, namely AF4, KDF4, HCF and BOB. Among them, AF4 is a device for uniformly opening the tow and applying glyceride. Figure 1 is a schematic diagram of the production process of AF4. Diacetate fiber tow enters the first-stage opener through the guide wire, and then enters the third-stage opener after passing through the second-stage opener, braking roller pair, input roller pair, and stretching roller pair. , and then apply the plasticizer through the glycerin spray box, and then enter the filter rod forming program through the guide roller pair and the collection roller, wherein, the opening rollers (including the braking roller pair, the input roller pair and the stretching roller pair) and the opening roller pair in AF4 The working state of the filter will affect the opening of the tow, thereby affecting the suction resistance and weight index of the filter rod. When any roller has surface wear, it may increase the SD of the suction resistance value and reduce the quality of the product.

In the actual production process, after the daily unit is put into production for a period of time, the cloth belt and anti-slip belt will be worn, resulting in reduced friction. In the case of variable speed operation such as starting and stopping of the unit, the cloth belt is prone to slipping, smoke, etc. The tow in the gun cannot move backwards, and the tow in AF4 cannot enter the bong through the high-pressure nozzle, and the tow in AF4 will be wound on the collection roller. In order to quickly clean the tow on the collection roller, stop the car Workers usually use a blade cutting method to cut off the twisted tow, which often takes a lot of time and affects production efficiency. At the same time, in the process of cutting with the blade, if the force is too strong, it will cut the surface of the collecting roller, causing the surface of the roller body to be damaged and rough and uneven. When the tow passes through the collecting roller, a small part of the tow will be caught by the surface of the roller The rough part is broken, resulting in uneven feeding of the tow at the high-pressure nozzle, which affects the suction resistance and weight index of the filter rod.

After replacing the new collection roller, the suction resistance SD was at a small value, around 68, but after a month of three shifts of production, the value of the suction resistance SD gradually increased, and on the last day of the three shifts The average reached 79.5, close to the assessment standard of 80. We also recorded the occurrence of wire winding on each machine, 43 times of wire winding occurred in one working day, and the surface of the collecting roller was also obviously scratched. At the same time, it takes 3 to 5 minutes to process the wire winding situation each time, which seriously affects the production efficiency of the filter rod.

Therefore, there is a need for a collection roll that is easy to handle and wrap around the wire, so as to improve the production efficiency of the filter rod.
