Abstract

A new type of pretreatment device in the tobacco blank box, including a control device, four moving knives, and four vertically moving lifting mechanisms. A single moving knife includes a moving knife holder and a cutting knife connected to the moving knife holder. The moving knife holder is connected with the corresponding lifting mechanism, and the moving knife holder is provided with a linear push mechanism arranged horizontally, and the linear push mechanism is connected with the corresponding cutting knife; there is a distance between adjacent cutting knives, and the cutting knife is vertically Arranged side by side; the control device is connected with the linear push mechanism and the lifting mechanism control. The utility model increases the gap of the cigarette block, and the penetration rate after pretreatment is above 98%. The tobacco flakes are loose and uniform, which reduces the crushing of tobacco leaves and reduces the consumption of tobacco flakes after moisture resurgence. Based on an annual output of 300,000 boxes, it can save about 30,000 kilograms of tobacco leaves.

Description

A new type of pretreatment device in the tobacco blank box

technical field

The utility model relates to a device for cutting and loosening tobacco blanks.

Background technique

At present, the slitting process of the blades in the silk workshop adopts the vertical slitting method of three knives and four pieces. Since the number of slitting blocks is relatively small, the thickness of the slit tobacco blocks is relatively thick, and the gaps in the tobacco blanks are small. , the warming and humidifying water cannot completely penetrate into the whole tobacco base, the average penetration rate is only 92.1%, and the unpenetrated cigarette block is in a dry core state, and the crushing rate reaches about 5% in the subsequent processing. Resulting in greater consumption of raw materials.

Utility model content

The purpose of the utility model is to provide a new type of pretreatment device in the tobacco blank box, which can increase the gap of the cigarette block and then increase the penetration rate.

The technical scheme of the utility model is:

A new type of pretreatment device in the tobacco blank box, including a control device, four moving knives, and four vertically moving lifting mechanisms. A single moving knife includes a moving knife holder and a cutting knife connected to the moving knife holder. The moving knife holder is connected with the corresponding lifting mechanism, and the moving knife holder is provided with a linear push mechanism arranged horizontally, and the linear push mechanism is connected with the corresponding cutting knife; there is a distance between adjacent cutting knives, and the cutting knife is vertically Arranged side by side; the control device is connected with the linear push mechanism and the lifting mechanism control.

The linear propulsion mechanism is an air cylinder.

The lifting mechanism is a chain transmission mechanism, and the chain transmission mechanism includes a chain connected with the knife holder and a driving device for driving the chain to lift.

The spacing between the four cutting knives is equal.

The utility model increases the gap of the cigarette block, and the penetration rate after pretreatment is above 98%. The tobacco flakes are loose and even, which reduces the crushing of tobacco leaves and reduces the consumption of tobacco flakes after rehydration. Based on an annual output of 300,000 boxes, it can save about 30,000 kilograms of tobacco leaves.

detailed description

As shown in Figure 1, a new type of pretreatment device in the tobacco blank box of the present utility model includes a control device, four moving knives 2, and four vertically moving lifting mechanisms 1, and a single moving knife 2 includes a moving knife Frame 3 and the cutting knife 4 that is connected on the movable knife rest 3, the movable knife rest 3 is connected with the corresponding elevating mechanism 1, the linear push mechanism that is provided with horizontally on the movable knife rest 3, and the straight push mechanism is cylinder 5 . The cylinder 5 is connected with the corresponding cutter 4; there is a distance between the adjacent cutters 4, and the cutters 4 are vertically arranged side by side; the distance between the four cutters 4 is equal.

The control device is connected with the cylinder 5 and the lifting mechanism 1 for control. The lifting mechanism 1 is a chain transmission mechanism, and the chain transmission mechanism includes a chain connected to the cutter knife rest 3 and a driving device for driving the chain lifting. Drive cutter knife rest 3 to move up and down.

The device is composed of a cross brace, a large left mobile frame, a small mobile frame, a large frame mobile cylinder assembly, a small frame mobile cylinder assembly and the like.

Working process: When automatically controlling the slicing machine, the four groups of cutters are lowered and inserted into the cigarette stack. In order to avoid the impact of cutting on the cigarette box and prevent the phenomenon of four groups of cutters being caught, the control program is designed with successive operation modes and action sequences. It should be: the outer knife is separated first, and the inner knife is separated later. In manual mode, when the four sets of cutters are inserted into the cigarette stack at the same time, if you press the wrong button, it should not work, and you can only move in order (first outside, then inside). After slitting, the cutting knife rises to lift the knife, and the cutting knife retracts in reverse order, first inside and then outside. That is to say, the whole action procedure is: when the time is divided, the outside is first and then the inside is in, and when the time is right, the inside is first and then the outside.

The utility model changes two movable knives and one fixed knife into four movable knives of the slicing machine, adopts one downward cutting action, the fork is divided into two actions, divides the cigarette pack into five parts, and adds corresponding control valve islands, cylinders, etc.

The moving knife is controlled by a servo cylinder, and the displacement in the horizontal direction of the moving knife is adjusted by the stroke of the servo cylinder. The strokes of the four cylinders are the same, and the stroke does not cause the cutting knife to jam.

The cutter frame is driven up and down by a chain, and the knife frame runs smoothly, eliminating the impact on the tobacco blanks, reducing material crushing, and avoiding excessive pressure, which will easily adhere to the bottom of the box after moisture regain.
