A die cutting machine unwinding device

Abstract

This utility model discloses a die-cutting machine unwinding device, including a worktable and a roll. A fixed side plate is fixedly connected to the top surface of the worktable, and a motor is fixedly installed on one side of the fixed side plate. A rotating rod is fixedly connected to the motor shaft, and a limiting protrusion is fixedly connected to the outer surface of the rotating rod. This utility model provides initial positioning of the roll with material wound on it by setting the limiting protrusion and limiting groove. By setting a fixed rod, rotating block, flipping limiting plate, through hole, connecting plate, screw, etc., the flipping limiting plate can be flipped to a vertical state and fixed after the roll is installed. Then, a sliding block drives the flipping limiting plate to move, so that the flipping limiting plate moves to contact one side of the roll and fixes its position. This further limits the installation of the roll with material wound on it, facilitating the installation and positioning of rolls with different widths, and is suitable for installing rolls of various widths.

Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to a die-cutting machine unwinding device. Background Technology

[0002] Die-cutting machines, also known as cutting machines or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. They utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or films into specific shapes. Die-cutting machines require an unwinding device during operation.

[0003] For example, Chinese utility model patent CN221850437U discloses a die-cutting machine feeding device and the die-cutting machine itself, including a connecting plate and a cleaning mechanism. One side of the connecting plate is provided with an unwinding mechanism for feeding material, and the cleaning mechanism is located on one side of the connecting plate for cleaning the material released by the unwinding mechanism. The cleaning mechanism includes multiple movable plates movably disposed on one side of the connecting plate, with brush bristles on their opposing surfaces. A pressing mechanism is provided between the movable plates and the connecting plate for the brush bristles to contact the material released by the unwinding mechanism. This utility model utilizes the arrangement of movable plates and brush bristles. The number of movable plates is two, and through the action of the pressing mechanism, the two movable plates tend to move relative to each other, ensuring that the brush bristles on the surface of the movable plates can contact the material surface, thereby brushing off dust from the material surface and preventing the material from carrying dust into the die-cutting machine, ensuring die-cutting quality and avoiding the need for subsequent separate cleaning of the die-cut material.

[0004] However, the existing die-cutting machine unwinding device has a convex strip on the outer wall of the rotating roller for limiting, and a groove on the inner wall of the winding ring to match the convex strip. The winding ring can be fitted onto the outer wall of the rotating roller, which is not convenient for installing and limiting the winding ring with materials of different widths.

[0005] Therefore, we propose a die-cutting machine unwinding device to solve the above problems. Utility Model Content

A connecting plate is fixedly connected to both sides of the connecting block. A through hole is opened on the top surface of the connecting plate. Multiple positioning threaded grooves are opened on the top surface of the workbench. A threaded connection is made to the threaded part of a screw rod in the positioning threaded groove. A smooth part of the screw rod is movably connected in the through hole. A limiting round block is fixedly connected to the top of the screw rod.

[0009] Preferably, multiple limiting guide rods are horizontally fixed in the groove, and guide holes are respectively opened at both ends of one side of the moving block, and the guide holes are slidably connected to the limiting guide rods.

[0010] Preferably, the inner wall of the drum is slidably connected to the rotating rod, one side of the flipping limiting plate contacts the drum, and the connecting plate two is slidably connected to the top surface of the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention provides initial positioning by using limiting protrusions and limiting grooves when installing a roll with material wound on it. By using a fixing rod, rotating block, flipping limiting plate, through hole, connecting plate, screw, etc., the flipping limiting plate can be flipped to a vertical position and fixed after the roll is installed. Then, the sliding block drives the flipping limiting plate to move, so that the flipping limiting plate moves to contact one side of the roll and fixes its position. This provides further positioning for the installed roll with material wound on it, making it convenient for installing and positioning rolls with different widths. It is suitable for installing rolls with a wider range of widths. Attached Figure Description

A flipping limiting plate 13 is fixedly connected to the top surface of the rotating block 12. A through hole 131 is formed on one side of the flipping limiting plate 13. A connecting plate 14 is fixedly connected to both sides of the flipping limiting plate 13. A through hole 2 141 is formed on the top surface of the connecting plate 14. Screws are formed at both ends of the top surface of the connecting block 10. The threaded groove 102 connects to the threaded part of the screw rod 15. The through hole 141 connects to the smooth part of the screw rod 15. A limiting block 16 is fixed to the top of the screw rod 15. Connecting plates 18 are fixed to both sides of the connecting block 10. A through hole 181 is opened on the top surface of the connecting plate 18. Multiple positioning threaded grooves 22 are opened on the top surface of the worktable 1. The threaded part of the positioning threaded groove 22 connects to the threaded part of the screw rod 19. The through hole 181 connects to the smooth part of the screw rod 19. A limiting block 20 is fixed to the top of the screw rod 19. During unwinding, the motor 3 is connected to an external power source. Starting the motor 3 drives the rotating rod 4 to rotate. The limiting protrusion 5 limits the rotation of the drum 6, allowing the drum 6 containing the material to rotate for unwinding.

[0025] Example 2:

[0026] Please see Figure 1-4 This is the second embodiment of the present invention. Based on the previous embodiment, multiple limiting guide rods 8 are horizontally fixed in the slide groove 7. Guide holes 91 are respectively opened at both ends of one side of the moving block 9. The guide holes 91 are slidably connected to the limiting guide rods 8, which can effectively limit the movement of the moving block 9 and improve the stability of the movement of the moving block 9.

[0027] The inner wall of the drum 6 is slidably connected to the rotating rod 4, and the flipping limit plate 13 contacts the drum 6 on one side. The connecting plate 18 is slidably connected to the top surface of the workbench 1.

[0028] The rotating block 12 has contact slots 101 on both sides, which can limit the rotating block 12 and prevent it from shifting. The flip-limiting plate 13 has contact slots 101, which makes it easy to flip the flip-limiting plate 13 to a horizontal or vertical state.

[0029] The bottom surface of the limiting block 16 contacts the bottom surface of the connecting plate 14, and the bottom surface of the limiting block 20 contacts the top surface of the connecting plate 28, thus serving as a limiting element.

[0030] The top surface of the limiting round block 16 is fixed to the rotating handle 17. The rotating handle 17 is provided with a protrusion to facilitate the rotation of the screw 15.

[0031] Please see Figure 1-4In use, the material-wound roll 6 is slid into the rotating rod 4 through the limiting groove 61 corresponding to the limiting protrusion 5 for initial limiting. Then, the flip limiting plate 13 is flipped, and the groove 101 can limit it. The flip limiting plate 13 can be flipped to a vertical state. By inserting the screw 15 into the through hole 141 and screwing it into the threaded groove 102, the flip limiting plate 13 in the vertical state can be fixed. Then, the flip limiting plate 13 is moved, and the moving block 9 moves and slides on the limiting guide rod 8. When the flip limiting plate 13 moves and contacts one side of the roll 6, the through hole 181 on the connecting plate 18 corresponds to the corresponding positioning threaded groove 22. The screw 19 can be inserted into the through hole 181 and screwed into the corresponding positioning threaded groove 22 to fix the position of the flip limiting plate 13. This can further limit the installation of the material-wound roll 6, which is convenient for installing and limiting rolls 6 with different widths. It is suitable for the installation of rolls 6 with more different widths.
