Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and specifically to a height limiting mechanism for a die-cutting machine. Background Technology

[0002] A die-cutting machine is a specialized mechanical device used in industrial production for cutting and creasing various materials. It uses molds to precisely cut and creasing materials such as paper, plastic, rubber, and metal foil. It is widely used in industries such as packaging, printing, electronics, and shoemaking to meet various processing needs such as product molding, decoration, and protection.

[0003] Specifically, the working principle of a die-cutting machine is to use a die-cutting plate fixed on the machine to press the material into the groove of the die through mechanical pressure, thereby achieving precise cutting and creasing of the material. The whole process can be completed automatically and is suitable for processing large batches of materials. In order to control the vertical movement range of the die-cutting cutter and ensure that it does not exceed the set safe height during processing to prevent damage to the base material or the machine itself, a height limit mechanism is often required. However, in actual operation, different cutting tasks often require different cutting heights, which makes it necessary for operators to frequently adjust the cutting height. During the adjustment of the cutting height, the height limit mechanism also needs to be adjusted simultaneously, resulting in excessive downtime of the die-cutting machine during adjustment, which affects the processing efficiency of the die-cutting machine.

[0004] In view of this, a height limiting mechanism for a die-cutting machine is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional height limiting mechanisms for die-cutting machines require adjustment of the height limiting mechanism when adjusting the cutter height, thus affecting processing efficiency, and to provide a height limiting mechanism for die-cutting machines.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a height limiting mechanism for a die-cutting machine, comprising a die-cutting machine body, the die-cutting machine body including a frame, a lower template fixedly connected to the frame and an upper template slidably connected to the frame, a height-adjustable movable plate slidably connected to the bottom of the upper template, a cutter detachably connected to the bottom of the movable plate, the cutter being used to cooperate with the die-cutting plate to die-cut the raw material, a screw being rotatably connected to the top of the movable plate, a threaded sleeve being threaded onto the screw, a rotating ring being fixedly connected to the top of the threaded sleeve, the rotating ring being rotatably connected to the upper template, the threaded sleeve being used to drive the movable plate to move up and down when rotated to adjust the height of the movable plate and thus limit the height of the cutter.

[0007] Preferably, the bottom of the upper template has a channel for the movement of the movable plate, and multiple sliding sleeves are fixedly connected in the channel. Multiple sliding rods adapted to the size of the sliding sleeves are fixedly connected to the top of the movable plate.

[0009] Preferably, a first gear is fixedly connected to the end of the rotating rod away from the second bevel gear, and a second gear that meshes with the first gear is rotatably connected to the upper template. The second gear is located at the bottom of the first gear, and a rack is meshed with the bottom of the second gear. The rack is slidably connected to the upper template, and a hydraulic cylinder is fixedly connected to the upper template. The extended end of the hydraulic cylinder is fixedly connected to the rack. The hydraulic cylinder is used to drive the rack to move when extending or retracting, so that the threaded sleeve rotates and thereby limits the cutter at different heights.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-7This utility model relates to a height limiting mechanism for a die-cutting machine, comprising a die-cutting machine body 1, wherein the die-cutting machine body 1 includes a frame 2, a lower template 4 fixedly connected to the frame 2, and an upper template 3 slidably connected to the frame 2. A height-adjustable movable plate 7 is slidably connected to the bottom of the upper template 3, and a cutter 6 is detachably connected to the bottom of the movable plate 7. The cutter 6 is used to cooperate with the die-cutting plate to die-cut the raw material. A screw 73 is rotatably connected to the top of the movable plate 7, and a screw sleeve 8 is threadedly connected to the screw 73. A rotating ring 9 is fixedly connected to the top of the screw sleeve 8, and the rotating ring 9 is rotatably connected to the upper template 3. When the screw sleeve 8 rotates, it causes the movable plate 7 to move up and down to adjust the height of the movable plate 7 and thus limit the height of the cutter 6.

[0027] During installation, the rotatable connection between the screw 73 and the top of the movable plate 7 can be achieved through a bearing. The bottom of the screw 73 is fixed to the inner ring of the bearing, and the outer ring of the bearing is fixed to the movable plate 7, allowing the screw 73 to rotate relative to the movable plate 7. Therefore, when the threaded sleeve 8 connected to the screw 73 rotates, it can drive the screw 73 to move in the vertical direction, thereby moving the movable plate 7 and the cutter 6 to adjust the height of the cutter 6 and the movable plate 7. It should be noted that the movable plate 7 acts as a height limiting component for the cutter 6, so that when the movable plate 7 is limited, it can also limit the height of the cutter 6, and when the movable plate 7 is adjusted, the height of the cutter 6 can be adjusted synchronously.

[0028] In addition, the bottom of the upper template 3 is provided with a channel 74 for the movement of the movable plate 7. Multiple sliding sleeves 72 are fixedly connected in the channel 74, and multiple sliding rods 71 ​​that are adapted to the size of the sliding sleeves 72 are fixedly connected to the top of the movable plate 7. The sliding sleeves 72 and sliding rods 71 ​​are used to limit the movement of the movable plate 7 in the horizontal direction. That is to say, the sliding of the movable plate 7 in the channel 74 is achieved by the sliding sleeves 72 and sliding rods 71. The sliding rods 71 ​​limit the displacement of the movable plate 7 in the horizontal direction so that the movable plate 7 can rise or fall with the screw 73 when the screw sleeve 8 rotates.

[0029] Specifically, a first bevel gear 10 is fixedly connected to the top of the rotating ring 9. The first bevel gear 10 is rotatably connected to the top of the upper template 3. A second bevel gear 11, which is offset from the first bevel gear 10, is meshed with the first bevel gear 10. A rotating rod 12 is fixedly connected to the second bevel gear 11. The rotating rod 12 is rotatably connected to the upper template 3. When the rotating rod 12 rotates, it drives the screw sleeve 8 to rotate to adjust the height of the movable plate 7. This arrangement allows the rotating rod 12 to convert the rotation of its part outside the upper template 3 into the power to drive the first bevel gear 10 to rotate, so that the screw sleeve 8 rotates accordingly.

[0030] Furthermore, the end of the rotating rod 12 away from the second bevel gear 11 is fixedly connected to the first gear 13. The upper template 3 is rotatably connected to the second gear 14, which meshes with the first gear 13. The second gear 14 is located at the bottom of the first gear 13. The bottom of the second gear 14 is meshed with the rack 15, which is slidably connected to the upper template 3. The upper template 3 is fixedly connected to the hydraulic cylinder 18. The extended end of the hydraulic cylinder 18 is fixedly connected to the rack 15. The hydraulic cylinder 18 is used to drive the rack 15 to move when it extends or retracts, so that the threaded sleeve 8 rotates and thus limits the cutter 6 at different heights. That is to say, adjusting the extension and retraction of the hydraulic cylinder 18 can adjust the rotation of the threaded sleeve 8 and the height of the cutter 6 and the movable plate 7. When the hydraulic cylinder 18 is stationary, it can keep the threaded sleeve 8 stationary to a certain extent, preventing the adjusted cutter 6 and the movable plate 7 from shifting during the cutting process.

[0031] In addition, a slider 16 with a T-shaped cross section is fixedly connected to the rack 15, and a groove 17 adapted to the size of the slider 16 is provided on the upper template 3. The slider 16 and the groove 17 can make the movement of the rack 15 more stable, while ensuring the stability of the cutter 6 and the movable plate 7.

[0032] It should be noted that the detachable connection between the cutter 6 and the movable plate 7 can be achieved through connecting parts such as screws. After the cutter 6 and the movable plate 7 are fixed, the movable plate 7 can limit the height of the cutter 6. At this time, adjusting the movable plate 7 can also adjust the height of the cutter 6, making it more convenient to adjust the cutter and reducing the downtime of the die-cutting machine when adjusting the cutter.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
