An automatic adjustment device for paper edge height of double flue

Abstract

The invention relates to an automatic paper edge height adjusting device for a double-cigarette-channel machine in the production process of a cigarette making machine. The device is characterized bycomprising inclined rollers, a support seat, servo motors, central shafts, end face cams, ejector pins, sliding blocks, upper clamping plates, lower clamping plates, compression springs, cylindrical pins and paper guiding rollers, wherein the inclined rollers are mounted on a small wall board through a bracket, the support seat is mounted on the small wall board, the servo motors are fixed on thesupport seat and fixedly connected with the central shafts, the central shafts are fixedly connected with the end face cams, the end face cams are in contact with the ejector pins, the ejector pins are movably mounted in the sliding blocks, and the upper clamping plates and the lower clamping plates are fixed in the support seat, two groups of up and down corresponding circular arc grooves are formed in the upper clamping plate and the lower clamping plate, and the cylindrical pins mounted on the sliding blocks and circular arc-shaped bulge parts of the sliding blocks can slide in the circulararc grooves of the upper clamping plates and the lower clamping plates. The device has the advantages that full-automatic closed loop action adjustment is achieved, the response speed is high, manualinterference is not needed, and the change of the paper tape path during adjusting can be reduced to the maximum degree as a result of the adjusting mode of the inclined rollers.

Description

technical field [0001] The invention belongs to tobacco machinery, and relates to a device for automatically adjusting the height of double flue paper edges in the production process of cigarette machines. Background technique [0002] In the double-flue high-speed cigarette machine, the double-width cigarette paper is cut online to form two equal-width paper strips, the front and the rear, and then enter the front and rear bongs respectively. Next, the paper edge (width direction) of each paper strip forms a height difference. This height difference is the overlap width of the cigarette paper when the shredded tobacco is rolled and shaped. It needs to be constant, otherwise it will affect the glue quality of the cigarette and the quality of the cigarette. Overlapping quality causes cigarette quality problems. Therefore, before rolling into cigarettes, the high-speed cigarette machine has been set to detect the height of the two paper tapes in the front and rear bongs respe...

Problems solved by technology

[0004] Although the traditional method is simple, it can only be adjusted manually before starting the machine, and the adjustment effect is relatively poor. The manual method has been unable to meet the production needs of high-speed cigarette machines; and the CN201610602899.3 method can solve the problems existing in the traditional method, but the structure is relatively complicated, and while ensuring the position of the paper tape is accurate, two paper tapes must be ensured The anti-counterfeiting stamp on the paper can be aligned, that is, to prevent the paper tape from moving in the direction of motion
