Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rotary die-cutting machine technology, and more specifically, to a universal blade holder for a rotary die-cutting machine. Background Technology

[0002] Die-cutting machines are mainly divided into three types according to the different printing methods: rotary die-cutting, rotary-flat die-cutting, and flat die-cutting. Since the rotary die-cutting machine operates with continuously rotating rollers, its production efficiency is the highest among all types of die-cutting machines. However, the die-cutting plate needs to be bent into a curved surface, which is relatively troublesome and costly, and technically challenging. Therefore, rotary die-cutting machines are often used for mass production.

[0003] Currently used die-cutting machines generally require a matching die holder. The die holders used today are generally of fixed length, which means that when you want to change to a different size of roller cutter, you need to change the die holder, resulting in low production efficiency. In addition, if you want to use different roller cutters, you also need to use a different size die holder, which leads to high production costs and is not conducive to large-scale use. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a universal blade holder for a rotary die-cutting machine, which solves the technical problems that the blade holders currently used in the prior art are generally of fixed length, which means that when you want to change to a different size of roller blade, you need to change the blade holder, resulting in low production efficiency. In addition, if you want to use different sizes of roller blades, you also need to equip different sizes of blade holders, resulting in high production costs and making it unsuitable for large-scale use.

The auxiliary component includes two auxiliary rods movably connected inside the clamping plate. The end of the auxiliary rod is fixedly connected to the sleeve tube in the first group, and the end of the auxiliary rod is rotatably connected to a first limiting frame.

[0009] As a preferred technical solution of this utility model, a first pressing component is provided on the outside of the auxiliary rod. The first pressing component includes two first screws that are slidably connected inside the first limiting frame. The first screws pass through the clamping plate and are movably connected.

[0010] As a preferred technical solution of this utility model, the first pressing assembly further includes a first pressing plate fixedly connected to the end of the first screw, the inside of the first pressing plate being slidably connected to the auxiliary rod and the outside of the sleeve tube in the first group, and a first nut being threadedly connected to the outside of the first screw.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. In this disclosure, a rotary air pump drives the first transmission rod to rotate, which in turn drives the transmission plate to rotate, which in turn drives the first rotating shaft to move, which in turn drives the pull plate to move, which in turn drives the second rotating shaft to move, which in turn drives the two clamping plates to move relative to each other, thereby changing the distance between the two clamping plates. This allows for the adaptation to roller cutters of different sizes, thereby reducing the need for a tool holder and reducing production costs. Furthermore, if it is necessary to change roller cutters of different sizes, it is not necessary to change the tool holder, saving the time of changing the tool holder and thus improving production efficiency.

[0017] 2. In this disclosure, by rotating the second nut, the second screw is moved, which in turn moves the second pressing plate, so that the second pressing plate abuts against the clamping plate, thereby restricting the position of the second limiting frame, and thus accommodating roller cutters of different sizes.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, a universal blade holder for a rotary die-cutting machine according to an embodiment of the present disclosure is illustrated, including a mounting plate 1. A first transmission rod 2 is rotatably connected to the top of the mounting plate 1. A rotary air pump 3 is fixedly connected to the top of the first transmission rod 2. A transmission plate 4 is fixedly connected to the outside of the first transmission rod 2. Two first rotating shafts 5 are fixedly connected to the top of the transmission plate 4. A pull plate 6 is rotatably connected to the outside of the first rotating shafts 5. A second rotating shaft 7 is rotatably connected inside the pull plate 6. A clamping plate 8 is fixedly connected to the bottom of the second rotating shaft 7. The clamping plate 8 passes through the mounting plate 1 and is slidably connected.

[0032] The rotary air pump 3 drives the first transmission rod 2 to rotate, which in turn drives the transmission plate 4 to rotate, which in turn drives the first rotating shaft 5 to move, which in turn drives the pulling plate 6 to move, which in turn drives the second rotating shaft 7 to move, which in turn drives the two clamping plates 8 to move relative to each other, thereby changing the distance between the two clamping plates 8. This allows for the adaptation to different sizes of roller cutters, thereby reducing the need for a tool holder and reducing production costs. Furthermore, if different sizes of roller cutters need to be replaced, there is no need to replace the tool holder, saving time on tool holder replacement and thus improving production efficiency.

[0033] Both the rotary air pump 3 and the motor 21 are electrically connected to the control device on the die-cutting machine.

[0034] like Figure 3 As shown, a reset auxiliary component is provided on the outside of the clamping plate 8. The reset auxiliary component includes a slide rod 9 fixedly connected to the outside of the clamping plate 8. A limit seat 10 is slidably connected to the outside of the slide rod 9. The bottom of the limit seat 10 is fixedly connected to the top of the mounting plate 1. A spring 11 is fixedly connected between the outside of the clamping plate 8 and the outside of the limit seat 10.

[0035] The clamping plate 8 drives the slide bar 9 to move, thereby compressing the spring 11. When the clamping plate 8 needs to return to its original position, the rotary air pump 3 can drive the clamping plate 8 to return to its original position. During this process, the spring 11 can provide some assistance.

[0036] like Figure 1As shown, the top of the mounting plate 1 is provided with a mounting assembly, which includes a mounting bracket 12 fixedly connected to the top of the mounting plate 1. The bottom of the mounting bracket 12 is fixedly connected to the top of the rotary air pump 3, and a sliding hole 13 is provided inside the mounting bracket 12.

[0037] The device can be connected to the die-cutting machine by placing bolts inside the sliding hole 13.

[0038] Other auxiliary parts can also be installed on the mounting bracket 12 to accommodate different types of die-cutting machines.

[0039] like Figure 5 As shown, one of the clamping plates 8 is provided with an auxiliary component inside. The auxiliary component includes a sleeve 15. There are four sleeves 15, which are divided into two groups and arranged opposite each other. The auxiliary component includes two auxiliary rods 14 that are movably connected inside the clamping plate 8. The end of the auxiliary rod 14 is fixedly connected to the sleeve 15 in the first group, and the end of the auxiliary rod 14 is rotatably connected to the first limiting frame 16.

[0040] The position of the auxiliary rod 14 is restricted by the first limiting frame 16, thereby restricting the position of the sleeve 15.

[0041] like Figure 5 As shown, a first pressing assembly is provided on the outside of the auxiliary rod 14. The first pressing assembly includes two first screws 17 that are slidably connected inside the first limiting frame 16. The first screws 17 pass through the clamping plate 8 and are movably connected.

[0042] like Figure 5 As shown, the first pressing assembly also includes a first pressing plate 18 fixedly connected to the end of the first screw 17. The inside of the first pressing plate 18 is slidably connected to the auxiliary rod 14 and the outside of the sleeve tube 15 in the first group. The outside of the first screw 17 is threadedly connected to a first nut 19.

[0043] By rotating the first nut 19, the first screw 17 is moved, which in turn moves the first pressing plate 18, so that the first pressing plate 18 abuts against the clamping plate 8. This restricts the position of the first pressing plate 18 and the position of the sleeve 15, thus accommodating rollers of different sizes.

[0044] like Figure 5 As shown, another clamping plate 8 is provided with an active component on its outer side. The active component includes a second transmission rod 20 movably connected inside the clamping plate 8. There are two second transmission rods 20, and the ends of the second transmission rods 20 are fixedly connected to the ends of the sleeve tube 15 in the second group.

[0045] like Figure 5As shown, the active component also includes a motor 21 fixedly connected to the end of the second transmission rod 20, and a second limiting frame 22 is fixedly connected to the outside of the motor 21.

[0046] The motor 21 drives the second transmission rod 20 to rotate, which in turn drives the sleeve 15 to rotate, thereby driving the roller cutter to rotate.

[0047] like Figure 5 As shown, a second pressing assembly is provided on the outside of the second limiting frame 22. The second pressing assembly includes a second screw 23 that is slidably connected inside the second limiting frame 22. The second screw 23 passes through the clamping plate 8 and is movably connected.

[0048] like Figure 5 As shown, the second pressing assembly also includes a second pressing plate 24 fixedly connected to the end of the second screw 23. The interior of the second pressing plate 24 is movably connected to the outside of the second transmission rod 20 and the sleeve 15 in the second group. The outside of the second screw 23 is threadedly connected to a second nut 25.

[0049] By rotating the second nut 25, the second screw 23 is moved, which in turn moves the second pressing plate 24, causing the second pressing plate 24 to abut against the clamping plate 8. This restricts the position of the second limiting frame 22, thus accommodating rollers of different sizes.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
