Description

High-speed cigarette transmission and aluminium foil paper packing plant

Technical Field

The utility model relates to the technical field of automatic cigarette packaging equipment, in particular to an improvement of a high-speed cigarette transmission and aluminum foil paper packaging device which is used for transmitting cigarettes conveyed by a die box belt to two wheels and preparing for packaging aluminum foil paper.

Background

The cigarette transfer wheel industry is commonly provided with a wheel or a first wheel, wherein the wheel is arranged at the head part of the GD main machine body and is positioned between a belt of a cigarette mould box and the wheel. The cigarette is formed for the first time, which is the starting point of package forming. If the cigarette quality defect exists in one wheel part, the material waste in all the subsequent steps is caused, so that once one wheel fails, great economic loss is caused.

The existing wheel mainly comprises a wheel body, a left claw mechanism, a right claw mechanism, a cigarette mold box and a return spring. The left claw mechanism and the right claw mechanism are driven to fold through the cam, and the spring is pulled between the left claw arm and the right claw arm to play a role in resetting the opened state of the claw arms.

The function and the working principle of a wheel are as follows: the cigarette packing machine has the function of transferring the arranged cigarettes conveyed by the belt from the mould box to two wheels to prepare for packing aluminum foil paper.

When the arranged cigarettes are stopped before one round, one round is just at the horizontal position, and the left claw mechanism and the right claw mechanism are both at the horizontal slightly-opened state. Inside pushing away the cigarette board and pushing away a cigarette into round of diaphragm capsule afterwards, then two teams of jack catchs tighten up about, prevent that a cigarette from shifting at a round of rotatory in-process, and a round of anticlockwise rotation is rotatory twice 90 degrees after that, rotate the cigarette to left end horizontal position, aim at the diaphragm capsule that two rounds of right sides are in horizontal position, wait to push away the cigarette board and push away a cigarette into two rounds of diaphragm capsules after the aluminium foil paper targets in place.

A coupler extends out of the mainframe box at one wheel and is connected with a wheel central shaft, and when the mainframe box gear rotates, one wheel rotates along with the wheel. The top end of the central shaft is fixed with a cam, and the central shaft transmits the motion to the cam through the clasping mechanism. The cam surface is contacted with the driven wheel on the long and short swing arms, and the swing arms can be pushed to rotate around the shafts when the cams rotate. The left and right clamping jaws are tightly held on the long and short swing arm shafts through screws, and when the swing arm shafts swing, the clamping jaws swing along with the swing arms, and finally the opening and closing movement of the clamping jaws is realized. Wherein, because the outer cam that former round adopted, the swing arm can't reset, reset spring plays and provides pretightning force and the effect that resets for the swing arm.

The prior round has the following technical problems:

1. the sealing protection is insufficient. The existing wheel is of a semi-open structure, only a cam and four swing arm rollers are arranged in a box body, and other elements are arranged outside the box body and lubricated by grease. The smoke dust is large at one wheel, the grease is easy to be stained with the smoke dust, the smoke dust easily enters a gap for connecting parts under a semi-open structure, the connecting part is gradually abraded, the connection is failed or locked, and finally one wheel of motion is inaccurate.

2. The occupied space is large. The left and right clamping jaws in the existing wheel are positioned in front of the cam, so that the whole wheel structure occupies a large space.

3. The spring has poor return stability. An existing wheel adopts an outer cam to push a swing arm to contract and close a left claw mechanism and a right claw mechanism, and a reset spring is adopted to pull the swing arm to open the left claw mechanism and the right claw mechanism. Since the spring is a flexible member, shock loads are easily generated when switching between compression and expansion rapidly, especially at high speeds.

4. The transmission efficiency is low. The left and right clamping jaws in the existing round are symmetrically arranged, and the cigarettes can be received and conveyed only by rotating 180 degrees, so that the conveying efficiency is low.

5. The lift return curve of the existing cam is very short, the curve corner is sharp, and the change is very violent. The unsmooth cam surface curve will cause the rigidity impact of cam follower, directly influences the life of driven gyro wheel, and the former round of cam follower rolls the diameter little, and the bearing capacity is effective, under great impact effort, very easily causes the damage of cam follower gyro wheel.

Therefore, a wheel has more defects in both structure and material selection, resulting in a higher failure rate. One round of failure, the main influence is cigarette quality. In a round of follow-up packaging process, there is not the device that carries out automated inspection to a cigarette quality, so in case a round of packing is invalid, not only can lead to the serious waste of production material, the very big waste of manpower and materials that can cause moreover.
