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. 7 . 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 press 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 pressure roller 70 further includes a wheel body 74 between the wheel surface 71 and the inner peripheral wall 72, and a plurality of equal parts of the wheel body 74 are respectively provided with an elastic hole 75, and the elastic hole 75 is connected with the wheel hole 73. The direction parallel to the virtual central axis runs through the wheel body 74. Through the design of these densely arranged elastic holes 75, the pressure roller 70 has ideal radial compression elasticity, so that the wheel surface 71 can be applied to the cardboard 60 with an appropriate pressure, ensuring The cardboard 60 will not be skewed during the moving process, and at the same time, no indentation will be caused to the cardboard 60 . In the embodiment of the accompanying drawings, the shape of the elastic hole 75 is circular, but other shape designs that can make the pressure roller 70 possess compression elasticity, such as ellipse, rectangle, etc., should naturally also be included in the scope of the present utility model. Not restricted by the embodiments shown in the drawings.

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 to disassemble and assemble the machine, in a preferred embodiment, the above-mentioned press roller 70 can be separated along the two adjacent elastic holes 75 to form a first joint as shown in FIG. The pinch wheel 70a at the end 76a and the second joint end 76b, this design allows the pinch wheel 70a to be directly assembled on the mold wheel 90, and then the two joint ends 76a, 76b are joined together with an adhesive.

Also, the utility model can also have other different embodiments. Fig. 5 is the appearance of another preferred embodiment of the utility model, and Fig. 6 is its section. The press roller 70b disclosed in this embodiment is based on the above press roller 70a, and its first joint end 76a and second joint end 76b are processed into concave first interface 77a and second interface 77b, wherein The first interface 77a is inlaid with a first bushing 78a, and the second interface 77b is inlaid with at least two second bushings 78b. The two bushings 78a, 78b are hollow made of metal and are used to assemble a fastener 80. The fastener 80, after the platen wheel 70b is assembled on the die wheel 90, its two interfaces 77a, 77b can be joined together.

The buckle 80 is made of steel material, and it looks like a chain link of a chain. The fastener 80 is composed of a body 81, a gasket 82 and two snap rings 83a, 83b. One end of the body 81 has a first pin 84a, and the opposite end has a second pin 84b. The two pins 84a, 84b The length is greater than that of the first and second bushings 78a, 78b, and are respectively inserted from one side of the two ports 77a, 77b and penetrate the first bushing 78a and one of the second bushings 78b. The washer 82 has a first hole 85a and a second hole 85b, and is assembled to the ends of the two pins 84a, 84b from the other side of the two interfaces 77a, 77b. The two clasps 83a, 83b are respectively assembled on the two pins 84a, 84b to prevent the two interfaces 77a, 77b from being separated.

As the second pin 84b of the fastener 80 is inserted into a different second bushing 78b, the matching state of the pressing wheel 70b and the die wheel 90 can be adjusted. To be clear, when the second pin 84b is inserted into the second bushing 78b on the outside, since the gap between the two interfaces 77a, 77b is relatively large, the hole diameter of the wheel hole 73 becomes larger, and the pressure wheel 70b and the die wheel 90 The fit is relatively loose; on the contrary, when the second pin 84b is inserted into the second bushing 78b inside, since the gap between the two interfaces 77a, 77b is relatively small, the diameter of the wheel hole 73 becomes smaller, and the press roller 70b and The fit of the die wheel 90 is relatively tight.

When the press rollers 70, 70a, 70b need to be replaced after being used for a period of time due to wear or other reasons, use a cutter to directly cut off the press rollers 70, 70a, 70b or remove the fastener 80.

As shown in Fig. 7, when the press roller 70b (70, 70a) is used, it is assembled in the mold wheel 90 of the carton making machine to make a 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 clamps the cardboard 60 between the two wheels 90 and 95, drives the cardboard 60 to pass between the two wheels through friction, and accepts operations such as slotting, punching or die-cutting, so that the cardboard 60 is placed on the surface of the press wheel. Under the moderate pressure of 71, it can keep moving in a straight line, neither skew nor indentation, so as to ensure the processing quality.

In addition, since the press rollers 70, 70a, 70 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.
