Abstract: A cellulose acetate particle aggregate, a preparation method therefor and an application thereof, which relate to the field of harm reduction additives in cigarettes. The cellulose acetate particle aggregate includes 49-99.5 wt % of cellulose acetate particles, 0-50 wt % of a second kind of particles, and 0.5-20 wt % of a binder. The preparation method involves selecting cellulose acetate particles and a second kind of particles in a certain ratio, or cellulose acetate particles alone, preparing particle aggregates by using an air fluidized granulation method while adding a binder thereto, and sieving the particle aggregates to obtain a cellulose acetate particle aggregate having a required particle size. The cellulose acetate particle aggregate has a porous structure, an irregular shape, and a rough and uneven surface, which help to improve the efficiency of filtering out particulate matters or one or more harmful ingredients in cigarette smoke.

Abstract: A cheek plate device for a stuffer box crimper, comprising a bracket, adjusting mechanisms, cheek plates, a base, a pair of nip rollers and thrust devices. The adjusting mechanisms, which can slide relative to the bracket, are arranged on the bracket, the cheek plates are installed on the inner sides of the adjusting mechanisms, a pair of identical brackets, adjusting mechanisms and cheek plates are symmetrically installed on each side of the pair of nip rollers and affixed on the base. The adjusting mechanisms have adjusting blocks and elastic devices, the elastic devices are installed at the ends of the adjusting blocks and push against the thrust devices, the thrust devices push the adjusting blocks via the elastic devices, and the adjusting blocks push the two cheek plates moving towards the sides of the pair of nip rollers.

Abstract: A cheek plate device is provided for a stuffer box crimper, which has brackets, adjusting mechanisms, cheek plates, a base frame and a pair of nip rollers. The adjusting mechanisms are mounted on the brackets, which can slide relative to the bracket. The cheek plates are mounted on the inside of the adjusting mechanisms. Two identical brackets, adjusting mechanisms and cheek plates are mounted symmetrically at two sides of the pair of nip rollers and affixed on the base frame. The cheek plate device further comprises fluid thrust devices, which include fluid inlets and cylinders located on the brackets. One end of the adjusting mechanism is inserted into and coupled with the cylinder. The fluid of the thrust device flows into the cylinders through the inlets and pushes, via the adjusting mechanisms, the cheek plates toward the sides of the nip rollers. The thrust device can work hydraulically or pneumatically.
