Description

Carton making machine press roller

technical field

The utility model relates to a paper pressing wheel of a carton making machine, in particular to a rubber wheel which has compression elasticity and can press a cardboard to prevent the cardboard from skewing and indentation during the moving process.

Background technique

As shown in Figure 1, a typical carton making machine 10 is composed of a feeding unit (Feeding Unit) 20, a printing unit (Printing Unit) 30, a slotting unit (Slotting Unit) 40 and a die cutting unit (Die Cutting Unit) 50, To perform feeding, printing, crimping and die-cutting of (corrugated) cardboard to be processed into cartons, respectively. Among them, depending on the needs of carton production, the printing unit 30 can be increased from one to two or more, so as to perform single-color, two-color or color printing (press, one printing unit can only print one color), the carton production of the accompanying drawings The machine 10 is exemplified by two printing sections 30 and 30a.

The carton making machine 10 transports the cardboard 60 into the machine 10 via the three rows of paper feeding wheels 21 provided by the paper feeding part 20 and the wheel box grid 22 ( FIG. 2 ) in cooperation with a moderately sized vacuum. The conveying system (not shown) is a completely closed system, which seals all gears, cams, wheel box grid lifting mechanism and interrupter mechanism inside, and controls the paper feeding wheel according to the wheel box grid 22 moving up and down 21 rpm.

When the machine is idling (interruption period), the wheel box grid 22 is at a high position, so the cardboard 60 is not in contact with the feed wheel 21 . Once the feed cycle has begun, the wheel box grid 22 is lowered from the elevated position of the supporting cardboard 60 around the feed wheel 21 so that the cardboard 60 can come into contact with the feed wheel 21 . At the beginning of the feeding cycle, the speed of the feeding wheel 21 is almost zero, but it can quickly accelerate to 100% of the machine tangential speed, and maintain this speed throughout the feeding stroke, and the cardboard 60 is transported to the first Between the upper feed wheel 31 and the lower feed wheel 32 of the printing section 30, it takes over and conveys between the upper printing wheel 33 and the lower printing wheel 34 to accept the graphic printing of the first color; then, by the second printing section 30a The upper and lower feed wheels 31a, 32a send the cardboard 60 between the upper and lower printing wheels 33a, 34a to carry out graphic printing of the second color; Under the cooperation of the creasing wheels 41, 42 and the upper and lower slotting wheels 43, 44, the creasing and slotting operations are carried out; then, the cardboard 60 is sent into the die-cutting section 50, and the upper and lower die-cutting wheels 51, 52 are used to The unneeded part of the cardboard 60 is cut off with cooperation, and perforations (ventilation holes, hand holes, etc.) are made on the cardboard when necessary. Finally, the folding and gluing operations are carried out through the folding part and the gluing part not shown in the figure, so that the desired carton can be obtained. For generally simple cartons, the grooved portion 40 is sufficient, and the die-cut portion 50 is unnecessary. On the contrary, when making more complex cartons, the die-cutting part 50 is not necessary;

Because the existing carton making machine lacks a proper device to restrict the linear movement of the cardboard during the process of using friction to transport the cardboard to each department for processing, the cardboard is easily skewed during transportation. Operations such as grooving and die-cutting were adversely affected.

Detailed ways

The appearance of the pressing wheel 70 of the carton making machine of the present utility model is shown in FIG. 3 . The platen roller 10 is made of materials with characteristics such as high elasticity, high friction coefficient, high wear resistance and high softness, such as polyurethane (PU for short), urethane (Urethane, commonly known as Youli glue) or the like. The latter is made into a ring shape, which includes a wheel surface 71 formed on the outer peripheral wall, which is used to make sliding contact with the (corrugated) cardboard 60 to be processed, and the friction force generated thereby drives the cardboard 60 to advance, and a wheel surface relative to the wheel. The inner peripheral wall 72 of the surface 71 is used to define a wheel hole 73 for assembling the press wheel 70 to the mold wheel 90 , as shown in FIG. 6 . It should be known that the press roller 70 disclosed in the utility model is suitable for the slotting part 40 and the die-cutting part 50 of the carton making machine 10 mentioned above. When the pressing wheel 70 is applied to the grooved part 40, the mold wheel 90 is the upper grooved wheel 43 illustrated in FIG. 1 , and the anvil wheel 95 that cooperates with the mold wheel 90 in FIG. ; If the platen wheel 70 is assembled in the die-cutting part 50, the die wheel 90 refers to the upper die-cutting wheel 51 illustrated in FIG. 1, and the anvil wheel 95 is the lower grooved wheel 44.

The platen wheel 70 further includes a wheel body 74 between the wheel surface 71 and the inner peripheral wall 72. The inner side of the wheel body 74 is provided with a plurality of fixed holes 74 arranged at equal intervals, and the outer side of the wheel body 74 is provided with a plurality of equidistant holes. Arranged elastic holes 76, the fixed holes 75 and the elastic holes 76 run through the wheel body 74 in a direction parallel to the imaginary central axis of the wheel hole 73, wherein the fixed holes 75 provide several pieces of diagonally configured screws 91 to cooperate with the metal ring 92 ( FIG. 6 ) Lock the pressing wheel 70 to the mold wheel 90 . As for the elastic holes 76, the aim is to make the pressure roller 70 obtain ideal radial compression elasticity, so that the wheel surface 71 can be applied to the cardboard 60 with an appropriate pressure, so as to ensure that the cardboard 60 will not be skewed during the movement process, and will not exert pressure on the cardboard at the same time. 60 causes indentation.

In the embodiment of the accompanying drawings, the shape of the elastic hole 76 is close to a rectangle, and the width of its outer side is greater than the width of the inner side. At the same time, the rectangular elastic hole 76 is inclined towards the rotation direction of the pressure roller 70. This arrangement It can make the pressure roller 70 easily deformed and generate elastic force when subjected to radial pressure. Again, the shape of the elastic hole 76 is not limited by the embodiment shown in the accompanying drawings, and other shape designs that can make the pressure roller 70 have compression elasticity, such as circular, oval, etc., should naturally also be included in the scope of the present utility model .

Since the platen wheel 70 disclosed in the above embodiments is in a closed state, the machine must be partially disassembled before being assembled to the mold wheel 90 during use. In order to avoid wasting man-hours for disassembling and assembling the machine, in a preferred embodiment, the above-mentioned press roller 70 can be separated along the two adjacent elastic holes 76 to form a first wheel, as shown in Figures 4 and 5. The design of the press roller 70a of the first joint end 77a and the second joint end 77b allows the press roller 70a to be directly assembled on the mold wheel 90, and then the two joint ends 77a, 77b are joined together with an adhesive.

When the press rollers 70, 70a need to be replaced after being used for a period of time due to wear or other reasons, the press rollers 70, 70a are directly cut off with a cutter.

As shown in Figure 6, when the press wheel 70a (70) is used, it is assembled in the mold wheel 90 of the carton making machine for rotational movement, and uses its wheel surface 71 to press the cardboard 60 to be processed, and cooperates with the counter-rotating anvil wheel 95 , the cardboard 60 is clamped between the two wheels 90, 95, and the cardboard 60 is driven to pass between the two wheels through friction, and accepts slotting, punching or die-cutting operations, so that the cardboard 60 is on the surface of the press wheel 71 Under moderate pressure, it can keep moving in a straight line without skewing or indentation, thus ensuring the processing quality.

In addition, since the press rollers 70, 70a have compressive elasticity, they can allow cardboards 60 of different thicknesses to pass through within a certain range, omitting the procedure of adjusting the gap between the cardboards.

Of course, the above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure or equivalent process conversion made by using the specification of the utility model and the contents of the accompanying drawings, or directly or Indirect applications in other related technical fields are all included in the scope of patent protection of the utility model in the same way.
