Description

Track differential cam mechanism based on carton material feeding unit

Technical Field

The utility model relates to the technical field of carton processing equipment, in particular to a track differential cam mechanism based on a carton feeding device.

Background

With the continuous development of the automatic feeding technology of the paper boxes, the front edge paper feeding has replaced the back type paper feeding in a large area to become the main stream of automatic feeding in the current paper box industry, and is widely applied to ink printers, paperboard grooving machines, die cutting machines, line-striking machines, box booking machines and the like. The advantages of leading edge paper feeding in practical applications for over ten years are not shown here. The following is mainly concerned with what is its greatest disadvantage. The strength of the paper board fed by the front edge paper feeding mechanism is obviously reduced to different degrees. The result is that (the lower strength paperboard is more prominent about 50 percent lower strength) is sufficient to significantly decrease the compressive strength of cartons produced by the carton industry. The development direction of low gram weight and high strength advocated by the current carton industry becomes a counter-current of wasting resources, labor, civil and financial traumas. Many carton manufacturers have to choose a high grade of base paper for the grammage of corrugated and facestock in order to ensure the compressive strength of the carton. This is sufficient to make a wide range of carton manufacturers overwhelming, especially when the base paper is priced. The technical breakthrough of solving the problem that the front edge paper feeding does not harm the corrugated paper becomes urgent. Is also a technical subject of urgent need for breakthrough by leading edge manufacturers.

The front edge paper feeding part in the market at present mainly comprises a paper feeding gearbox and a paper feeding frame, the basic principle is that a main machine inputs a uniform speed transfer synchronous with the working period of the main machine to the gearbox, and the main machine outputs a motion which is uniformly accelerated, is transited to be uniformly decelerated and is then transited to be intermittent to be at one period of tail to be transmitted to a paper feeding rubber wheel on the paper feeding frame through the gearbox (the main machine is directly a cam divider). And then the paperboard above the rubber wheel is tightly adhered to the arc surface of the rubber wheel under the action of wind negative pressure below the divider according to the left periodical rotary motion of the motion curve of the divider. And the paper board is sent out to the main machine rubber wheel in a static state according to a curve track of uniform acceleration under the action of the rubber wheel. When the paper board reaches the center of the glue shaft, the linear speed of the paper feeding glue wheel (at the moment, on the transition section after uniform acceleration) just reaches synchronization with the speed of the glue shaft, the paper board enters the glue shaft and is then strongly pressed down by the glue shaft (at the moment, the rear part of the paper board is mostly on a table top, the paper board is separated from the glue wheel under the action of a machine, but the negative pressure acts on the paper board to be adsorbed on the movable outer surface to form strong resistance for advancing the paper board), and in such a state, the paper board is advanced forward by being forced by the rolling force generated by the glue shaft and the lower shaft on the paper board (at the moment, the advancing speed of the paper board is synchronous with the linear speed of a host machine). And (5) conveying the paper to a printing unit to finish one-time paper conveying process. The rolling damage of the glue shaft and the lower embossing shaft after the paper board enters the glue shaft when the strength of the paper board is damaged can be seen throughout the whole paper feeding process. If the pressure between the glue shaft and the embossing shaft is reduced, most of the paper board is adsorbed on the paper lifting board. The glue shaft must overcome the forward resistance caused by the negative pressure on the paper board. Therefore, only the rubber shaft pressure can be adjusted, and if the pressure is too high, the corrugated board collapses, so that the strength is damaged.
