Description

Re-cured tobacco frame chain conveying device

Technical Field

The utility model relates to a chain conveyor especially relates to a redrying cigarette frame chain conveyor.

Background

As is known, before redrying, tobacco leaves are usually sorted, put into a tobacco frame with a plurality of holes distributed on the surface, and sent into a steaming room for moisture regain treatment. In order to improve production efficiency, utilize band conveyer to shift to the tobacco leaf that the letter sorting is good to the height at tobacco leaf letter sorting line usually at present, then drop into the tobacco frame that is located chain conveyor through the hopper of being connected with band conveyer with the tobacco leaf again, can shift to the tobacco frame that fills with the tobacco leaf to evaporate the room through chain conveyor and carry out the conditioning.

At present, a chain conveying device for conveying cigarette frames generally comprises two conveying chains arranged on a frame, a motor for driving the conveying chains to move, and a brake device for braking the motor. Because the cigarette frame is bulky, the loading capacity is also big, in order to facilitate the hoist and mount to shift, the cigarette frame generally adopts thin wall stainless steel plate and iron frame that distributes and has a plurality of bleeder vents to constitute, therefore the cigarette frame self weight is also heavier. The following conditions exist in the process of driving the cigarette frame to move by the conveying chain:

1) Because the cigarette frames are placed on the conveying chains by self weight, the conveying chains drive the cigarette frames to move by friction force; when the motor stops rotating, the tobacco frame can continuously slide forward for a certain distance relative to the conveying chain due to the inertia effect, so that the hopper and the tobacco frame are staggered, and tobacco leaves are scattered.

2) Because the cigarette frame both sides do not have spacing guider, the cigarette frame motion route takes place the skew easily, and this also is the reason that causes the cigarette frame can't be adjusted well with the hopper.

3) As the tobacco leaves are relatively fluffy, the stacking height of the tobacco leaves exceeds that of the tobacco frames and the tobacco leaves are scattered outwards in the framing process, and the preset loading weight of the tobacco leaves in each frame cannot be reached. For this purpose, the tobacco leaves in the tobacco frame must be compacted by means of a ram arranged in the hopper. If the cigarette frame and the hopper can not be aligned correctly, the cigarette frame plate can be damaged by the pressure head.

In order to avoid the above situation, in actual production, multiple operators are usually required to repeatedly move and correct the position of the cigarette frame in a coordinated manner so as to ensure that the cigarette frame is aligned with the funnel. Not only has high labor intensity, troublesome operation and low efficiency, but also has great influence on the correction effect by human factors. In addition, sliding friction exists between the conveying chain and the rack, the resistance is large, and the chain is easy to wear. Thirdly, in the process that the pressure head compacts the tobacco leaves, the conveying chain is easy to damage due to frequent impact pressure.

Disclosure of Invention

To the above-mentioned defect that prior art exists, the utility model aims at providing a tobacco frame location is convenient accurate, carry not fragile redrying tobacco frame chain conveyor of chain.

In order to achieve the purpose, the utility model adopts the following technical proposal that the device comprises two conveying chains which are horizontally arranged on a frame, a motor which drives the two conveying chains to move, and a braking device which brakes the motor; two positioning cylinders which are fixed on the frame and electrically connected with the control device are arranged between the two conveying chains, and a positioning block is fixed on a piston rod of each positioning cylinder; guide rods parallel to the conveying chains are fixed on both sides of the rack; two supporting cylinders which are fixed on the frame and electrically connected with the control device are arranged at the outer sides of the two guide rods, and a supporting block is fixed on a piston rod of each supporting cylinder; one side of the frame is provided with a photoelectric switch electrically connected with the control device.

The front end of the guide rod is bent towards the arc of one side of the frame; the lower part of the conveying chain is provided with a strip-shaped base plate which is fixed on the frame and made of polytetrafluoroethylene.

Compared with the prior art, the utility model discloses owing to adopted above-mentioned technical scheme, consequently at least, have following advantage:

1) Because two positioning cylinders controlled by the control device are arranged between the two conveying chains, the cigarette frame can be prevented from sliding forwards due to inertia when the conveying chains stop moving, and the accurate positioning of the moving direction of the cigarette frame is realized;

2) Because the guide rods are fixed on the two sides of the rack, the four supporting legs positioned at the bottom of the cigarette frame can be limited and guided, so that the cigarette frame is ensured not to deviate in the moving direction;

3) Because two supporting cylinders are arranged on two sides of the frame, the cigarette frame can be jacked upwards through the four supporting legs after the cigarette frame is positioned, so that pressure impact on the conveying chain in the tobacco leaf compacting process by the pressure head can be avoided, and the conveying chain is prevented from being damaged;

4) The backing plate fixed on the frame can effectively reduce the motion friction resistance of the conveying chain, thereby reducing the abrasion of the conveying chain and prolonging the service life.
