The box pasting and folding machine comprises a machine frame, a paper rolling shaft, a glue barrel and a paper cutter. The glue barrel can slide up and down in the vertical direction of the machine frame, detachable glue distributing wheels are arranged in the glue barrel, and pawls abut against the outer contour faces of the glue distributing wheels. A shell type moving bar is arranged on the part, located in front of the glue barrel, of the machine frame, and at least a row of outer air suction holes communicated with a shell cavity is formed in the outer wall of the moving bar in the axial direction. An air suction barrel is arranged in the moving bar shell cavity in sealed and sliding modes, and an extraction hole communicated with an inner cavity of the air suction barrel is formed in the shaft body of an extending section and communicated with an air extractor. A row of inner air suction holes is formed in the wall of the air suction barrel. A sliding frame is arranged on a sliding rail in a sliding mode. A sliding table is connected to a fixed guide rail in a sliding mode, a movable holding plate and a fixed holding plate are arranged on the sliding table in parallel, and a pair of paper conveying press rollers is correspondingly arranged behind the paper cutter. According to the box pasting and folding machine, ground paper can be quickly corrected, the glue distributing amount is sufficient, glue lines are uniform, and the box pasting quality is good.

In order to meet the requirements of the appearance of the carton (box) and the visualization of the information of the items in the box, a carton (box) with a visual window has been widely used in product outsourcing in recent years. In order to ensure the overall sealing performance of the carton (box) , when making this type of paper (box) box, it is necessary to paste a layer of transparent window film on the blank paper window. At present, it is completed by a special window sticking machine. Although this special window sticking machine can complete the film sticking of the blank paper window, there are still some shortcomings in the actual use of the machine: on the one hand, because the machine is an independent machine, it is different from the It is necessary to use the corresponding model for matching the standard folder gluer. The production and selection of various models is very inconvenient in actual matching, and the blank paper pasted with the window film has to be manually transferred to the subsequent folder gluer On the machine, this reduces the degree of automation of production and affects the production efficiency of the machine; It is too long, takes up too much space, and the blank paper correction channel is long, and the paper correction speed is relatively slow, which affects the production speed of the machine. Obviously, it has the defects of large space occupation and slow paper correction speed; on the other hand, in the current window paste The glue distribution method used on the machine is nothing more than the traditional "paste cylinder storage, butterfly viscose glue" and "rotary wheel glue", among which the "paste cylinder storage material, butterfly viscose glue" method can Realize the glue distribution on the edge of the blank paper window, but because the blank paper is continuously transported forward by the conveying system set on the machine during work, the longitudinal butterfly plate set on the machine can be conveniently realized on the longitudinal edge of the window For the glue distribution on the lateral edge of the window, it is necessary to add a horizontal synchronous motion system that is synchronized with the base paper on the machine, set the horizontal glue distribution disc on the motion system, and follow the motion system together Traveling longitudinally, during this process, the horizontal glue dispensing butterfly completes the glue dispensing operation on the horizontal edge of the window, and after the horizontal glue dispensing operation is completed, the horizontal glue distributing butterfly will follow the motion system to make a quick return trip and return to the glue dispensing The starting point is to glue the window of the next blank paper. This kind of horizontal synchronous motion system not only has a complex structure, but also has high manufacturing costs. Pattern, make the same pattern on the side of the outer ring of the rubber wheel and then hollow out the cloth glue, the abdominal cavity of the rubber wheel stores glue, the blank paper is continuously conveyed forward in a straight line during work, the rubber wheel contacts the blank paper by rotating, The glue in the abdominal cavity of the rubber wheel overflows to the glue line around the blank paper window at the hollow of the rim to complete the glue distribution. Compared with the paste cylinder storage and butterfly glue method, its structure is relatively It is simple and can realize the gluing of the window vertically and horizontally at one time, but because the gluing wheel used in the roller gluing method is usually an integral structure, its width cannot be adjusted, and the horizontal width of the window of various cartons is not the same. , when the width of the blank paper window changes during production, it is necessary to order cloth rubber wheels with corresponding width specifications, so that many specifications of cloth rubber wheels can be formed on one machine, and the production of many specifications of cloth rubber wheels is not only for manufacturing and Storage brings a lot of inconvenience, and it also increases the cost of using the machine. There are too many specifications and high cost of use. In addition, when the runner is used to glue the blank paper cloth with a large water absorption, such as corrugated cardboard, it is often caused by glue. The viscosity of the liquid makes it difficult to flow out from the rolling glue groove, which results in insufficient actual glue distribution and uneven glue lines, resulting in too fast water absorption of the blank paper, which seriously affects the adhesiveness of the glue, and is prone to window The phenomenon of film degumming; on the other hand, the window film used for pasting the window on the current window pasting machine is supplied by the film supply system. The film supply system usually includes a film roll with a certain damping installed on the paper reel. The paper conveying roller of the film, and the paper cutter for cutting the paper film, the paper film covers the window of the blank paper under the traction and rolling of a pair of paper conveying rollers and moves forward together with the blank paper. When the length of the paper film When the length required to cover the window is reached, the paper cutter moves to cut the paper tape. This method of damping the end of the paper tray and pulling and tensioning the window film by the paper delivery roller can realize the cutting of the paper tape. However, the damping applied to the paper tray should not be too large when the paper feeding roller pulls the paper, otherwise it will cause the paper feeding roller to slip and affect the normal transportation of the blank paper and film. The high impact force will easily cause the paper tray to slip and overshoot the rotation, and the paper belt stretched between the paper tray and the paper feeding roller will loosen. When the paper cutter cuts the paper, the cutting impulse will be weakened due to the loose paper, forming The paper cutting is not smooth, the edge of the cut paper is not neat, and the length of the cut window film will be different, resulting in quality problems that the width of the paper film from the upper and lower edges of the window is not equal after the window is pasted, and the paper cutter is on the frame. There is always a certain space on the top, and there is always a certain distance between the paper head of the cut paper tape and the paper delivery roller, and the paper head can only be placed on the viscose base paper, and the base paper is brought into the paper delivery press roller. During this process, the window film is pulled forward by the glue on the base paper, and there will inevitably be slippage between the window film and the base paper, which will easily cause the width of the upper edge of the base paper window to be too narrow or expose the core, forming a Defective products or waste products, so the film cutting and feeding structure used in the current film laminating machine obviously has the defects that the paper film is not tight when cutting the film, the cutting film is not smooth, and the paper film cannot be directly sent to the paper delivery roller.
