Description

Pin shaft feeding device of automatic pin installing equipment of copper bar chain of filament cutter

The technical field is as follows:

the utility model belongs to the technical field of the thin slice tobacco processing former, concretely relates to automatic round pin axle feedway of selling equipment of dress of filament cutter copper bar chain.

Background art:

in the tobacco shred production line, a tobacco cutter is an important main machine device, and the main task of the tobacco cutter is to cut processed tobacco leaves and tobacco stems into cut leaves and cut stems which meet the requirements of the tobacco shred production process specification. The filament cutter conveyer of filament cutter is mainly chain conveying, including upper chain, lower chain and sprocket, and the upper and lower chain is compacted into "cigarette cake" and is conveyed to the sword door with different speed according to the volume that sets for the supplied materials of conveying hopper.

The chain block is an important component of the conveying device of the tobacco cutter, the chain block is generally made of tin bronze materials, one copper chain block is formed by connecting a plurality of chain block links through pin shafts, and the chain block links are chain plates. The chain bank can produce very big pulling force and wearing and tearing at long-term operation's in-process for the chain bank appears the problem that length increases and thickness reduces, and after the chain bank is elongated, chain bank sag increases, and phenomena such as skidding, shake often can appear in tobacco cutter chain bank conveying system in the operation process, thereby make the pipe tobacco thickness of cutting out uneven, the flow is unstable, hole off tracking scheduling problem, shred quality also correspondingly receives the influence, the chain bank that needs to be renewed this moment. In the use of the copper gang chain, because dust, smoke and oil and water vapor in the environment pollute seriously, the easy accumulated smoke and scale of the gang chain cause the change of the gap between the copper gang chain and the knife gate seat, the conveying copper gang chain can contact the knife gate seat, the cutting circumferential gap of the knife roller is reduced, and the equipment can be stopped due to failure in serious conditions. Therefore, the conveying copper bar chain needs to be detached and cleaned regularly. In any case, the copper gang chain needs to be disassembled, and the gang chain section is butted and then installed on the equipment again after being replaced or cleaned.

At present, in the pin dismounting and mounting process of the chain, two modes of manual dismounting and mounting or machine dismounting and mounting are adopted. The manual disassembly and assembly operation mode is flexible, when the pin is disassembled, the pin shaft between the adjacent chain links needs to be knocked out manually, when the pin is assembled, the pin shaft is knocked into the space between the adjacent chain links manually, the labor intensity of workers is high, the force and the direction of manually knocking the pin shaft are not easy to control when the pin shaft is knocked, the stress of the pin shaft is easy to deflect, and the deformation of the chain links in rows can be caused when the pin shaft is seriously knocked. The problem that artifical dismouting exists is not solved, the technical staff develops the machine dismouting, for example patent number ZL201720929152.9, the name is the chinese utility model patent of "row chain link dress round pin equipment for filament cutter", the chain link dress round pin equipment that this patent discloses can realize the machine dress round pin of the round pin axle of row chain, it discloses the round pin axle workbin that the splendid attire round pin axle was used, the round pin axle in the round pin axle workbin is automatic to roll to the round pin axle constant head tank on the round pin axle conveying roller in, then by round pin axle push cylinder propelling movement between the chain link, realize the dress round pin action.

The utility model has the following contents:

in summary, in order to overcome the defects of the prior art, the utility model provides a pin shaft feeding device of the automatic pin installing equipment of the copper bar chain of the filament cutter, which is a new pin shaft feeding mode, an inclined supporting plate is arranged below the discharge hole of the pin roll blanking box, an air cylinder for pushing the pin roll is arranged on the supporting plate, the inclined direction of the supporting plate is from the discharge hole of the pin roll blanking box to the air cylinder, the supporting plate is arranged obliquely downwards, meanwhile, the distance between the supporting plate and the discharge hole of the pin shaft blanking box is 1.2 to 1.5 times of the diameter of the pin shaft, the existence of the distance ensures that only one pin shaft falls down onto the supporting plate every time, and the obliquely arranged supporting plate ensures that the falling pin shaft cannot directly roll down, therefore, only one pin shaft is pushed into the pin penetrating guide groove by the air cylinder at each time, the pin shaft feeding device is novel in conception, simple in structure and convenient to use, and automatic feeding of the pin shafts can be achieved.
