Description

Technical Field

[0001] This utility model relates to a die-cutting machine, specifically to a plate and frame anti-detachment guide device for a die-cutting machine. Background Technology

[0002] A die-cutting machine is a specialized device for post-printing paper processing. The die-cutting unit of a die-cutting machine uses a pressure plate and a waste removal plate to perform printing and waste removal operations. These plates are typically housed within a frame. When processing requirements change, the frame needs to be pulled out of the die-cutting unit to replace the required pressure plate or waste removal plate. To ensure the stability of the frame's position during extraction, a guiding device is usually required. Traditional guiding devices typically use a single lower support guide wheel structure. In practice, this structure may cause the frame to tilt, affecting its normal extraction. Furthermore, the support guide wheels are usually fixed, and different frames, pressure plates, or waste removal plates may have varying height requirements for entering the die-cutting machine, leading to significant limitations in its application. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a plate frame anti-detachment guide device for a die-cutting machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A die-cutting machine's frame anti-fall-off guide device includes mounting plates arranged on the left and right sides at the inlet and outlet of the frame. The mounting plates are movably mounted on the machine frame and connected to a lifting and adjusting assembly. An upper positioning guide wheel is rotatably mounted on each mounting plate, and a lower support guide wheel is positioned below the upper positioning guide wheel. The lower support guide wheel is mounted on a movable frame. A first elastic element is provided between the movable frame and the mounting plates. Both ends of the movable frame have arc-shaped portions that can be pressed against the front and rear ends of the frame. The top of the arc-shaped portions is flush with the lower support guide wheel. A mounting base is provided on the mounting plate, and a positioning pin is movably mounted within the mounting base. A second elastic element is provided between the positioning pin and the mounting base. Positioning holes for the positioning pin to be inserted are provided on the frame.

[0006] The lifting and adjusting assembly includes an adjusting screw that is rotatably mounted on the frame. The adjusting screw is screwed to a mounting plate, and a guide assembly is provided corresponding to the mounting plate.

[0007] Both the first elastic element and the second elastic element are springs.

[0008] The arc-shaped portion is disposed on the mounting block, and the mounting block is detachably disposed on the movable frame.

[0009] A handle is provided extending from the outer wall of the positioning pin.

[0010] The die-cutting machine's anti-fall-off guide device for the die-cutting frame, as described above, sets the lower support guide wheel on the movable frame. This allows the movable frame, under the action of an elastic element, to drive the lower support guide wheel to press the top of the die-cutting frame firmly against the upper positioning guide wheel, achieving upper positioning and guiding support for the die-cutting frame. This ensures the die-cutting frame will not tilt during pulling, further improving the stability of the die-cutting frame's movement. Furthermore, by setting the mounting plate as a liftable structure, the overall height of the die-cutting frame can be adjusted by raising and lowering the mounting plate, effectively improving its flexibility and adapting to different specifications of die-cutting frames, imprinting plates, and waste removal plates.

[0011] The present invention includes the following figures:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 This is a structural schematic diagram of the plate frame mounting plate of this utility model;

[0014] Figure 3 This is a structural diagram of the plate frame of this utility model. Detailed Implementation

[0015] As shown in the figure, the die-cutting machine anti-detachment guide device disclosed in this utility model includes mounting plates 3 arranged on the left and right sides at the inlet and outlet of the die-cutting machine. Each mounting plate 3 is movably mounted on the machine frame. The mounting plates 3 are connected to the lifting and adjusting components. An upper positioning guide wheel 8 is rotatably mounted on the mounting plate 3. A lower support guide wheel 14 is arranged below the upper positioning guide wheel 8. The lower support guide wheel 14 is mounted on the movable frame 13. A first elastic element 15 is arranged between the movable frame 13 and the mounting plate 3. Both ends of the movable frame 13 are provided with arc-shaped parts 11 that can be squeezed against the front and rear ends of the die-cutting machine 1. The top of the arc-shaped parts 11 is flush with the lower support guide wheel 14. A mounting seat 2 is provided on the mounting plate 3. A positioning pin 9 is movably mounted in the mounting seat 2. A second elastic element is arranged between the positioning pin 9 and the mounting seat 2. A positioning hole 16 is provided on the die-cutting machine 1 for the positioning pin 9 to be inserted.

[0016] Furthermore, the lifting and adjusting assembly includes an adjusting screw 5 rotatably mounted on the frame, which is screwed to the mounting plate 3. A guide assembly is provided corresponding to the mounting plate 3, including a slide 6 connected to the mounting plate 3, and a slide rail 7 on the frame that mates with the slide 6. With this structure, the mounting plate 3 can be raised or lowered by controlling the rotation of the adjusting screw 5. Alternatively, a linear motor can be used to drive the mounting plate 3 to raise or lower, achieving electric control adjustment.

[0017] Furthermore, both the first and second elastic elements are springs.

[0018] Furthermore, the arc-shaped portion 11 is provided on the mounting block 12, and the mounting block 12 is detachably mounted on the movable frame 13. With this structure, the easily worn arc-shaped portion 11 can be easily replaced.

[0019] Furthermore, a handle 10 is provided extending from the outer wall of the positioning pin 9. This facilitates manual disengagement of the positioning pin 9 from the positioning hole 16 on the plate frame 1, thereby enabling the plate frame 1 to slide.

[0020] Using the above technical solution, when the plate frame 1 needs to be sent in or pulled out, the plate frame first squeezes the arc-shaped part 11, causing the movable frame 13 to descend a certain distance and squeeze the spring, so that the distance between the upper positioning guide wheel 8 and the lower support guide wheel 14 is just adapted to the thickness of the plate frame, realizing the upper positioning guide support of the plate frame 1, ensuring that the plate frame will not tilt during the pulling process, and further improving the stability of the plate frame movement; when the plate frame 1 is pulled out until the positioning hole 16 is aligned with the positioning pin 9, the positioning pin 9 will be inserted into the positioning hole 16 under the action of the elastic element to realize the positioning of the plate frame 1 and prevent it from falling off. If it is necessary to pull out the plate frame completely for replacement, the positioning pin 9 can be manually pulled out from the positioning hole 16; when it is necessary to adjust the height of the plate frame, the plate frame 1 can be raised and lowered by controlling the rotation of the adjusting screw 5 to adjust its height, improving its flexibility of use.
