Fixture for adjusting blocking rail of PROTOS cigarette-making machine

Abstract

The invention discloses a fixture for adjusting a blocking rail of a PROTOS cigarette-making machine. The cigarette-making machine comprises a twisting drum, grooves are uniformly formed in the circumference of the outer surface of the twisting drum, a clearance is preset between the cutting edge of the blocking rail and the bottom of the grooves, the fixture is arranged in the clearance, the fixture comprises an arc surface body and correcting bar arc surfaces positioned at two ends of the inner side of the arc surface body, the shape of the correcting bar arc surfaces adapt to that of the grooves, and the circle centers of each correcting bar arc surface and the arc surface body are opposite; the outer arc surface of the arc surface body is coaxial with the twisting drum, the outer arc surface is used as an adjusting reference surface, and the height of the outer arc surface higher than the bottommost of the grooves in the radial direction is equal to the clearance; and the correcting bar arc surfaces lean to the interiors of the grooves. The improved fixture is applied to the PROTOS70 (ZJ17) or PROTOS90E (ZJ112) cigarette-making machine, and can be used for eliminating the factors for adjusting the clearance errors between the blocking rail and the twisting drum, avoiding repeated adjustment, and improving the work efficiency. Proven by use, the fixture disclosed by the invention has the advantages that a common maintenance worker can finish calibration of the blocking rail only in 5 minutes by using the fixture and a rework phenomenon is not produced.

Description

technical field [0001] The invention relates to a coiling unit, in particular to a device for adjusting the blocking rail of the coiling unit. Background technique [0002] When the PROTOS crimping unit completes the cigarette rubbing process, the gap between the blocking rail and the rubbing drum must be adjusted precisely to meet the cigarette rubbing quality. At present, the working efficiency of the tooling used to adjust the gap is very low, and the adjustment accuracy is poor, which affects the operation of equipment and product quality. [0003] 1. The working principle of the blocking rail [0004] Such as figure 1 As shown, the rubbing drum 1 of the PROTOS coiling unit is evenly provided with several wheel grooves 9 on the outer circle. During the rubbing of cigarettes by the PROTOS crimping unit, the "cigarette group 2" with glued tipping paper on the rubbing drum 1 (filter in the middle and non-tip cigarettes at both ends) Combination) is lifted out of the whe...

AI Technical Summary

Problems solved by technology

In the actual adjustment process, there are the following problems: First, the adjustment operation is inconvenient. Because the cylindrical school stick 10 is adopted, the cutting edge of the blocking rail 3 and the school stick 10 are in line contact. When the fastening screw 5 of the blocking rail is loosened and the blocking rail is 3 When pushing upwards towards the school stick 10, the school stick 10 is very easy to slip off

The second is that the accuracy of the adjustment result is poor. The diameter of the rubbing drum 1 is 258mm. It is very difficult to make the center of the wheel groove 9 on the line connecting the center of the rubbing drum 1 and the cutting edge of the blocking rail 3. It is very difficult to judge only by visual inspection. As a result, if the center of the wheel groove 9 deviates from the center of the rubbing drum 1 and the cutting edge of the blocking rail 3 at an angle of 0.5°, the gap deviation between the blocking rail 3 and the wheel groove 9 is 0.203mm. If the center of the wheel groove 9 deviates from the rubbing drum 1 If the angle between the center and the cutting edge of the blocking rail 3 is 1°, the gap deviation between the blocking rail 3 and the wheel groove 9 is 0.893mm

In order to ensure the adjustment accuracy as much as possible, after each adjustment, repeated proofreading is required, which affects the debugging progress. It takes 30 minutes for a skilled maintenance worker to adjust the blocking rail
