Description

Cutter head assembly

Technical Field

The utility model relates to the technical field of cigarette cut-tobacco processing equipment, in particular to a cutter head assembly.

Background

In the tobacco shred production line of a cigarette factory, boxed tobacco shreds come out of a raw material warehouse to a shred production workshop to be disassembled into cartons through a box disassembling machine, the boxlike tobacco shreds are cut into even small pieces through a slicing machine, the small pieces of tobacco shreds are heated and humidified into loose tobacco leaves through a loosening and conditioning machine, and the tobacco leaves enter the next working procedure through a hemp shred removing machine. The raw materials of the tobacco flakes are hydraulically packed and boxed in a redrying factory, and the boxed tobacco flakes have the storage time of two to three years of alcoholization stage; the weight of each box of cigarettes is 200 kg, and the stacked stacking among the cigarettes (usually 3 bags) can cause the extrusion of the lower cigarette bags, so that the cigarette stacks are compact and are not easy to loosen; based on the self characteristics of tobacco leaves, tobacco leaf raw materials with sufficient oil content are easier to adhere and are not easy to loosen when being extruded. Therefore, after the boxed tobacco flake raw materials are sliced by a slicing machine, a small amount of tobacco flakes which are not damped and loose completely still exist after the loosening treatment of the loosening and damping cylinder for heating and damping, namely tobacco leaves are stuck together to form cakes, which is called as 'cake tobacco'.

Wherein, the amount of the cake smoke after being processed by the loosening and conditioning machine is directly related to the return permeability which is an important technological index of the procedure. According to statistics, a batch of cigarettes is fed with 8000 kg, and cake cigarettes of one type of cigarettes have about 30 kg; the cake weight of the second type of cigarettes is about 60 kg. After loosening and conditioning, tobacco leaves and cake cigarettes are separated through a star roller type hemp thread removing machine, the loose tobacco leaves enter the next working procedure, the cake cigarettes are removed through a blanking hopper, and the removed cake cigarettes are added into the next working procedure after being manually torn.

The above method for processing the cake cigarettes is a method commonly adopted in the industry, but the manual cake cigarette processing method mainly has the following problems: the operator needs to tear the tobacco flakes off the tobacco cakes one by one, and the labor efficiency is low.

Therefore, it is necessary to provide a cutter head that can be used to tear pieces of tobacco one by one from a cake of tobacco, thereby replacing the manual work with a direction of study by those skilled in the art.

The stationary knife 82 has a double-edged structure, and has a cutting edge 91 above and at one end. The fixed cutter 82 has the main function of cutting and separating when the cutter disc 33 runs to drive the large cake smoke to pass through the fixed cutter 82, so that the running load of the equipment is reduced.

In some embodiments, the stationary blades 82 are symmetrically disposed, and are disposed in a pointed configuration on a side of the stationary blades 82 facing the cutterhead 33 assembly 21. The cutter disc 33 is convenient to operate to cut and separate when the large cake smoke is driven to pass through the fixed cutter 82, and the operation load of the device is further reduced.

In some embodiments, as shown in fig. 6-8, the cutterhead 33 assembly 21 includes a spline shaft 31, on which a plurality of cutterheads 33 and a plurality of eccentric sleeves are mounted on the spline shaft 31, wherein adjacent cutterheads 33 are mounted in a staggered manner, and the eccentric sleeves are mounted between adjacent cutterheads 33, wherein the eccentric direction of adjacent eccentric bushings 34 is consistent.

The cutterhead 33 assembly 21 consists of a spline shaft 31, a cutterhead 33, an eccentric bushing 34 and a round nut 5435. The cutterhead 33 assembly 21 is the main component of a single-shaft cake-tobacco loosening machine. The spline shaft 31 is a transmission main shaft of a single-shaft type cake tobacco loosening machine, one end of the spline shaft 31 is provided with a shaft shoulder 32, and a plurality of cutterheads 33 and eccentric bushings 34 are arranged on the spline shaft 31. When in installation, the first cutterhead 33 is firstly installed close to the shaft shoulder 32 of the spline shaft 31, and then the first eccentric bushing 34 is installed close to the first cutterhead 33; the second cutterhead 33 is arranged next to the first eccentric bushing 34, the first cutterhead 33 and the second cutterhead 33 are arranged in a staggered mode when being arranged, then the second eccentric bushing 34 is arranged next to the second cutterhead 33, the second eccentric bushing 34 is arranged in a consistent mode with the first eccentric bushing 34 in an eccentric direction, and therefore the cutterhead 33 and the eccentric bushing 34 are arranged in sequence; finally, a round nut 5435 is installed, and the round nut 5435 tightly connects the cutterhead 33 and the eccentric bush 34 together.

For example: the second cutterhead 33 is mounted on the first eccentric bush 34 in a 60-degree offset manner, and the second eccentric bush 34 is mounted on the second cutterhead 33 in an eccentric manner with the first eccentric bush 34. The cutterhead 33 and the eccentric bushing 34 are thus mounted in sequence, and finally the retaining washer and the round nut 5435 are mounted.
