Abstract
Description
Technical Field
[0001] The invention relates to the tobacco production industry, and in particular to a novel guide rail regulating device for accurately controlling the amount of tobacco shreds conveyed by a cigarette-making machine suction belt in cigarette production. Background Art
[0002] The weight of cigarettes is one of the key indicators of cigarette quality. Cigarettes that are too light or too heavy will be rejected as waste. Therefore, cigarette weight control is particularly important in the process of feeding and forming cigarettes in cigarette making machines. Existing cigarette making machines such as ZJ17 and ZJ118 mainly control the weight of cigarettes through the tobacco weight adjustment system. The amount of tobacco passing through is controlled by controlling the gap between the suction belt that transports the tobacco and the flattening plate that trims the thickness of the tobacco, thereby achieving cigarette weight control. Front adjustment blocks and rear adjustment blocks are installed between the two sides of the tobacco channel and the flattening plate. The two adjustment blocks are used to prevent tobacco from leaking sideways. Because the distance between the flattening plate and the suction belt needs to change with the change of tobacco, the height dimensions of the front adjustment blocks and the rear adjustment blocks need to change accordingly. The height dimensions of the front adjustment blocks and the rear adjustment blocks on the existing equipment are designed into three specifications to meet the change of the distance between the flattening plate and the suction belt. This adjustment method is troublesome to change the specifications, and the satisfaction level is low. It cannot achieve stepless adjustment of height, so it cannot accurately control the supply of tobacco. Summary of the invention
[0003] The technical purpose of the present invention is to provide an adjustable front adjustment block and a rear adjustment block in the chopper guide rail component of the tobacco conveying channel of the cigarette making machine to meet the distance change between the flattening disk and the suction belt. This method avoids the trouble of replacing standard parts, and can realize stepless adjustment of the distance change between the suction belt and the flattening disk, thereby accurately controlling the supply amount of tobacco.
[0004] The present invention specifically adopts the following scheme:
[0005] A novel guide rail adjustment device includes a front adjustment block, a rear adjustment block, a connecting block, a bracket, a nut plate, an adjusting screw, a scale plate, a slider and a slider fixing block. The two ends of the connecting block are respectively connected to the bracket and the front adjustment block and the rear adjustment block. The bracket is fixed on a small wall panel where a suction ribbon transmission device is installed in a cigarette making machine; the slider is connected to the slider fixing block and fixed on a chopper guide rail for controlling the movement direction of the suction ribbon in the cigarette making machine; the scale plate and the adjusting screw are fixed on the bracket; the slider between the front adjustment block and the rear adjustment block is connected to the slider fixing block and fixed on the base of the chopper guide rail; the bracket equipped with the scale plate and the adjusting screw is fixed on the small wall panel of the equipment. By rotating the adjusting screw, the front adjustment block and the rear adjustment block are driven to move up and down to meet the distance change between the flattening disk and the suction ribbon, and the supply of tobacco shreds is accurately controlled.
[0006] As a further improvement of the above solution:
[0007] The adjusting screw and the scale plate are fixed on the bracket. The flange of the adjusting screw is embedded in the groove of the connecting block. Rotating the adjusting screw can drive the connecting block to move up and down. There are scale lines on the connecting block. The scale lines on the scale plate correspond to the scale lines on the connecting block, and the specific data of the up and down adjustment can be read.
[0008] The bottom surfaces of the slider, the slider fixing block and the connecting block are made into a hollow structure, which is used to ensure that there is enough negative pressure to absorb the tobacco through the device.
[0009] The front adjustment block, the rear adjustment block, the connecting block and the nut plate assembly are sleeved on the slider; the front adjustment block and the rear adjustment block are fixed to the connecting block through the nut plate, assembled on the slider, and slidably cooperate with the slider. The bottom surface of the slider is used to support the suction wire, and the side surface of the slider plays a positioning and guiding role, so that the adjustment block moves up and down smoothly.
[0010] The connecting block is designed with a convex dovetail, and the bracket is designed with a concave dovetail. The convex dovetail of the connecting block can slide in the concave dovetail of the bracket.
[0011] The leveling plate is fixed on the chopper transmission of the cigarette making machine and is used to scrape off excess tobacco and adjust the thickness of the tobacco. The suction belt is a mesh belt structure. The tobacco is adsorbed on the suction belt under the action of negative pressure and is transported to the required position. The guide rail is fixed on the wind chamber of the cigarette making machine and is a transportation channel for the tobacco.
[0012] The advantages of the present invention are:
[0013] 1. The present invention ingeniously converts the spiral motion of the adjusting screw into the linear motion of the connecting block, thereby driving the front and rear adjusting blocks to move up and down.
[0014] 2. The present invention realizes stepless adjustment of the height of the adjustment block, and can accurately adjust the gap value between the adjustment block and the equipment leveling plate, thereby accurately controlling the delivery amount of tobacco.
[0015] 3. The scale plate designed in the present invention can intuitively read the specific size value of the adjustment.
[0016] 4. The present invention has compact structure, convenient operation and high running precision.
[0017] 5. The present invention can provide equipment with adaptability to tobacco shred structure.
[0018] 6. The present invention can be promoted and applied on medium and high speed cigarette making machines such as ZJ17, ZJ118 and ZJ116. BRIEF DESCRIPTION OF THE DRAWINGS
