Description

Technical Field

[0001] The utility model belongs to the technical field of equipment for the back-end process of the packaging and printing industry, and specifically relates to a non-stop flatbed die-cutting machine for roll paper. This technology can be fully applied to a flatbed hot stamping machine. Since the flatbed die-cutting machine and the flatbed hot stamping machine have the same properties, for the sake of simplicity, the following description will only take the flatbed die-cutting machine as an example. Background Art

[0002] When the current web-fed flatbed die-cutting machine is working, the running direction of the die-cutting blade table is perpendicular to the running direction of the paper. The paper must be paused and wait for the die-cutting to be completed before it can continue to run. Compared with the web-fed round die-cutting machine, the paper is die-cut without stopping during continuous operation. The working speed of the former is significantly lower than that of the latter. The advantages and disadvantages of the above two die-cutting machines are: the advantage of the web-fed flatbed die-cutting machine is that it is easy to make plates and the cost is low, and the disadvantage is that the efficiency is low, while the disadvantage of the web-fed round die-cutting machine is that it is difficult to make plates and the cost is high, and the advantage is that the efficiency is high. It can be seen that the current two die-cutting machines are not ideal in terms of plate-making cost and efficiency. Summary of the invention

[0003] The purpose of the utility model is to overcome the defects and shortcomings mentioned above and to provide a non-stop flat-bed die-cutting machine for roll paper, that is, the roll paper does not need to be paused, and the die-cutting knife plate table follows the speed of the roll paper to perform die-cutting non-stop during movement. Obviously, its efficiency will be greatly improved, and the speed can reach the level of a circular-circular die-cutting machine, so that it has the dual advantages of easy plate making, low cost and high work efficiency.

[0004] The technical solutions adopted by the utility model to achieve its purpose are as follows:

[0006] Compared with the prior art, the utility model has the following beneficial effects: when die-cutting a roll paper, it is not necessary to stop the paper for die-cutting when the die-cutting blade plate moves in a direction perpendicular to the direction of paper travel as in the prior art. The upper die-cutting blade plate table (7) and the lower die-cutting bottom plate (11) of the roll paper non-stop flatbed die-cutting machine follow the speed of the roll paper and move at the same speed and direction at the moment of die-cutting, and die-cutting is completed without stopping during movement.

[0010] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0011] A non-stop flat-bed die-cutting machine for roll paper, the machine comprises a wall panel (1), a bearing (2), a gear (3), a gear (4), an eccentric main shaft (5), an upper die-cutting blade table (7), a multi-row flat rolling bearing (10), a lower die-cutting bottom plate (11), a bottom table (12) and a roll paper (14), characterized in that two eccentric main shafts (5) are mounted on both sides of the wall panel (1) through bearings, the two eccentric main shafts (5) are of the same size and shape, and are arranged and installed according to the same eccentric position elements, and one end of the two eccentric main shafts (5) is mounted with a gear (3). Figure 1 A gear (4) driven by a servo motor is installed between the two gears (3); a pair of bearing holes are respectively provided on both sides of the upper die cutting knife plate (7), which are installed at the eccentric position of the two eccentric main shafts (5) through bearings (2). Figure 1 and Figure 2 When the gear (4) rotates, it drives the two gears (3) to rotate synchronously in the same direction. Figure 3 , then the two eccentric spindles (5) drive the upper die-cutting knife plate platform (7) to run at a linear speed of V=2πrn (r=eccentricity of the eccentric spindle n=number of revolutions of the eccentric spindle). Obviously, all points on the upper die-cutting knife plate platform (7) run at the same linear speed V; the upper die-cutting knife plate platform (7) has four holes at four corners, and the lower die-cutting base plate (11) has four columns (6) at four corners, and the two are slidably connected; the lower die-cutting base plate (11) has slide rails (13) on both sides of the bottom end, and the base (12) has inherent slide grooves (9) on both sides. Constrained by the slide grooves (9), the lower die-cutting base plate (11) follows the upper die-cutting knife plate platform (7) to make linear motion and reciprocate on a multi-row flat rolling bearing (10) (multi-row needle bearings are used for better effect), and the multi-row flat rolling bearing (10) is arranged on the upper surface of the base (12). At this time, if the running speed of the web is V, then the linear speed of the upper die-cutting blade table (7) is also V. When the circular motion reaches the lowest point, the die-cutting line knife (8) on the upper die-cutting blade table (7) meets and is tangent to the lower die-cutting bottom plate (11) in linear motion, and the die-cutting is completed in motion. The upper die-cutting blade table (7) in circular motion has a tangential speed of V, and the linear speed of the web (14) is V. At the moment of die-cutting, the speed error is very small and can be completely ignored.

[0012] To achieve the requirement of completing one die-cutting operation in one rotation of the spindle, the width of the web (14) to be die-cut is not necessarily exactly equal to the stroke S of the eccentric spindle (5) in one rotation. For example, the web speed is 5 m / s (300 m / min), the linear speed of the upper die-cutting blade table (7) is V = 2πrn = 5 m / s, and the spindle eccentricity r = 0.025 m, it can be known that

[0013] n=V / 2πr=5 / 2πr=31.847 (revolutions) / s, that is, the web (14) travels 5m / s and the eccentric spindle (5) rotates 31.847 times, driving the upper die-cutting knife plate (7) to perform 31.847 die-cuts. Therefore, it is necessary to adjust the servo motor to have two speeds, fast and slow, running alternately. The fast speed is used for die-cutting, which is controlled within the range of half a rotation of the eccentric spindle (5). The other half of the rotation is slow and is used to wait for the web (14) to continue to move into place, and then quickly start to follow the web to perform die-cutting, completing the requirement of performing one die-cutting after one rotation of the spindle.

[0014] The present invention is described in accordance with the embodiments. Without departing from the principle, the present invention can also be modified and improved. It should be pointed out that any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
