Description

Technical Field

[0001] This invention relates to a die-cutting mold, and more particularly to an adjustable mold suitable for die-cutting cigarette packs. Background Technology

[0002] Cigarettes are a type of tobacco product. They are made by drying tobacco, cutting it into shreds, and then rolling it into a cylindrical strip about 120mm long and 10mm in diameter. To smoke, one end is lit, and the smoke is inhaled from the other end. Cigarettes are typically packaged in cigarette boxes. The production of cigarette boxes generally uses low-cost laser-cut wooden boards. The process involves using a laser to cut slits in a wooden board or a blade-fixed board. Then, workers use a specialized cylindrical fixing device to hammer the blade into the slits, creating a die for stamping and cutting. The die is then fixed in place. While it can be installed on a stamping machine, during installation, workers typically need to apply double-sided tape to fix the die. Due to the narrow space of the die on the stamping machine, the space for fixing with bolts is limited, and the position needs to be manually calibrated by the operator, which is inaccurate. It is also inconvenient to disassemble the die plate or the blade. On the other hand, during use, due to the limited time, the blade is prone to side deviation or peeling off of the carbonized layer, which requires replacement. In the existing technology for replacing blades of laser wood die-cutting, the die needs to be removed first, and then the blades need to be pulled out one by one using a pull-out tool, which is very inefficient.

[0003] Therefore, there is an urgent need for an adjustable die for cutting cigarette packs to solve the above problems. Summary of the Invention

[0007] Preferably, a torque gearbox is fixedly connected to the inner wall of the clamping plate, and a rotating convex plate is fixedly connected to the output end of the torque gearbox. A chamfered bevel is formed on the inner top of the clamping plate, and a concave space is formed on the bottom surface of the sliding table. The sliding table is slidably connected to the bottom slide rail of the mold body. A micro motor is installed inside the sliding table, and its output end is meshed with the rotating end of the torque gearbox through a transmission component. A battery and controller are installed on the side of the micro motor. The micro motor can be selected as a four-by-eight mm hollow cup servo motor. A return spring is provided between the positioning plate and the lifting hole.

[0008] Preferably, a pressing mechanism is fixedly connected to the side wall of the mold body. The pressing mechanism includes at least four hydraulic cylinders on the side wall. A lifting plate is fixedly connected to the top output end of each hydraulic cylinder. A rotating plate is rotatably connected to the top of the lifting plate. A pressing plate is fixedly connected to the top of the rotating plate. The rotating plate and the pressing plate are fixedly connected by bolts. A protrusion is provided on the bottom surface of the pressing plate.

[0009] Preferably, an adjustment mechanism is slidably connected inside the bottom side of the mold body. The adjustment mechanism includes an adjustment column, an adjustment gear is engaged with the adjustment column at the toothed end, a rotating rod is fixedly connected to the side end of the adjustment gear, and an adjustment plate is fixedly connected to the side end of the rotating rod.

[0010] Preferably, a stamping mechanism is fixedly connected to the top of the mold body. The stamping mechanism includes a bracket, a hydraulic press is fixedly connected to the top and bottom surfaces of the bracket, a stamping plate is fixedly connected to the bottom of the hydraulic press, and at least two electromagnets are fixedly connected to the center of the bottom surface of the stamping plate.

[0011] Preferably, a sorting mechanism is fixedly connected to the bottom end of the stamping mechanism. The sorting mechanism includes two side supports. A servo motor is fixedly connected to the inner side of the side supports. A sorting platform is fixedly connected to the inner rotating end of the servo motor. A recycling bin is slidably connected to the side end of the sorting platform.

[0012] Preferably, the outer surface of the magnet is flush with the bottom surface of the mold body, the bottom surface of the electromagnet is flush with the bottom surface of the stamping plate, and the magnets have opposite magnetic poles.

[0013] Preferably, the bottom end of the bracket is fixedly connected to two fixed support components and two controllable telescopic support components.

[0014] Preferably, the stamping mechanism is provided with a top plate, the clamping mechanism is provided with a blade at its bottom end, and the blade is slidably connected in a slot on the surface of the mold plate, wherein the slot on the surface of the mold plate is a laser slot.

[0015] Compared with the prior art, the adjustable die for cigarette packaging provided by the present invention has the following advantages:

[0016] 1. Through the coordinated operation of the clamping mechanism, the pressing mechanism, and the mold body, the blade can be inserted to a limit during mold installation. The blade position can also be flexibly adjusted and initially fixed after adjustment. The blade can be quickly disassembled during disassembly. At the same time, the installation and disassembly of the mold body can also be completed using an electromagnet, which greatly reduces the time for installing and disassembling the blade and the mold body. Overall, the installation efficiency is greatly improved. The installation and fixing of the blade is more flexible, and the position of the mold body is more accurate, making the die-cutting mold faster, more accurate, and more flexible in use.

[0017] 2. Through the coordinated operation of the mold body and the adjustment mechanism, the depth of the mold plate can be adjusted before the blade is installed, thereby adjusting the length of the blade protrusion. This makes the blade installation and adjustment process faster and more efficient. At the same time, the adjustment length is determined by the number of teeth, and the length can be more accurate, which greatly improves the efficiency of blade installation and adjustment and saves time.

[0018] 3. Through the cooperation of the stamping mechanism and the sorting mechanism, the blades and die plates can be quickly recycled after disassembly. At the same time, the limiting effect of the inclined plane prevents the blades from scattering. When sorting the table, the debris on the table can also be sorted and recycled, thus keeping the platform clean and tidy and avoiding the situation where debris affects the stamping work. This greatly improves the efficiency of sorting and recycling blades, die plates and debris, and reduces the sorting process for workers.

[0019] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0035] To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] like Figures 1 to 9 As shown in the figure, an adjustable die for cigarette packaging provided by an embodiment of the present invention includes a die body 1. A plurality of clamping mechanisms 2 are slidably arranged inside the die body 1. Each clamping mechanism 2 includes a sliding table 201. Two sliding groove plates 202 are fixedly connected to the top surface of the sliding table 201. Two clamping plates 203 are slidably connected to the inner sides of the two sliding groove plates 202. At least two clamping springs 204 are fixedly connected between the two clamping plates 203. Lifting holes 207 are provided at the bottom ends of the two clamping plates 203. A positioning plate 208 is slidably connected to the inner side of the lifting holes 207. Before stamping, the die plate 8 should be cut using a laser. Then, the position of the clamping mechanism 2 in the die body 1 is adjusted according to the cut shape. The sliding table 201... The bottom is a concave frustum, which has low friction and can slide and rotate quickly in the groove on the surface of the mold body 1. After adjusting several sliding tables 201 to the appropriate positions, the stamping mechanism 7 is provided with a top plate. The clamping end of the clamping mechanism 2 clamps the blade 6. The blade 6 is slidably connected to the slot on the surface of the mold plate 8. The slot on the surface of the mold plate 8 is a laser slot, which can limit the blade 6 at the corresponding position by the chamfered slope of the clamping plate 203, and then insert the blade 6. At this time, the rotating convex plate 205 is in a horizontal stationary state and does not affect the insertion of the blade 6. At the same time, the insertion of the blade 6 causes the clamping plate 203 to move to both sides. The clamping spring 204 provides the clamping force of the blade 6, so that the blade 6 can maintain the clamped state even without the mold plate 8. Figure 5As shown, in an optional embodiment, a return spring is provided between the positioning plate 208 and the lifting hole 207. Due to the movement of the clamping plate 203, the positioning plate 208 moves downward within the lifting hole 207, and finally the bottom end of the positioning plate 208 contacts the sliding groove of the mold body 1. Due to the contact of the bottom end of the positioning plate 208, the contact area between the clamping mechanism 2 and the mold body 1 is increased, and the friction is increased. Thus, the clamping mechanism 2 can fix the position while clamping the blade 6. In this way, the position of the sliding table 201 and the insertion and fixing of the blade 6 can be flexibly adjusted as needed by adjusting the sliding table 201. During operation, the blade 6 in the first slot can be initially installed and fixed quickly, improving the overall installation efficiency of the inserted blade 6.

[0037] like Figure 1 , Figure 4 and Figure 6 As shown, in an optional embodiment, an adjustment mechanism 4 is slidably connected inside the bottom side of the mold body 1. The adjustment mechanism 4 includes an adjustment column 401, an adjustment gear 402 is meshed with the side end of the adjustment column 401 at the toothed end, a rotating rod 403 is fixedly connected to the side end of the adjustment gear 402, and an adjustment plate 404 is fixedly connected to the side end of the rotating rod 403. After the blade is adjusted, due to the stamping requirements, the length of the blade protruding from the mold plate 8 is slightly different. At this time, the adjustment plate 404 on the side end of the mold plate 8 can be rotated, thereby driving the rotating rod 403 and the adjustment gear 402 to rotate, thereby adjusting the adjustment column 401 to rise and fall, thereby raising the adjustment column 401 to a certain distance. When the mold plate 8 is pressed down, it will be stopped by the adjustment column 401 and will no longer be pressed down, so that the mold plate 8 stays in a certain position, thereby making the exposed part of the blade reach a certain length requirement.

[0038] like Figures 1 to 9As shown, in an optional embodiment, a pressing mechanism 3 is fixedly connected to the side wall of the mold body 1. The pressing mechanism 3 includes at least four hydraulic cylinders 304 on the side wall. A lifting plate 303 is fixedly connected to the top output end of each hydraulic cylinder 304. A rotating plate 302 is rotatably connected to the top of the lifting plate 303. A pressing plate 301 is fixedly connected to the top of the rotating plate 302. The rotating plate 302 and the pressing plate 301 are fixedly connected by bolts 305. The bottom surface of the pressing plate 301 is provided with protrusions. In traditional die-cutting molds, each blade needs to be hammered with a hammering tool, which is very troublesome. At the same time, in order to ensure the integrity of the mold plate 8, the die-cutting mold cannot be pushed out from the bottom upwards, but is hammered into the slot from the top downwards. This causes considerable trouble for the installation work, and this process wastes a lot of time. In this invention, a first slot that does not affect the integrity of the mold plate 8 is first cut out using laser cutting, and then a second slot that is inserted from the top downwards is cut out. The first slot has two slots. The blade position is adjusted according to the shape of the first slot. After aligning the plate with the first slot, the hydraulic cylinder 304 is activated to retract, causing the lifting plate 303 and rotating plate 302 to descend, which in turn causes the lower pressure plate 301 to press down. The protrusion at the bottom of the lower pressure plate 301 prevents the blade from obstructing its descent during the pressing process, thus pressing the mold plate 8 to its lowest point. Bolts 305 provide a fixing function. Further, a pressing action completes the insertion of all blades 6 into the first slots. Then, utilizing the flared shape of the laser cutting groove, the blades 6 are shallowly inserted into the remaining second slots according to their positions. After insertion, the hydraulic cylinder 304 is activated again, causing the lower pressure plate 301 to press down, pressing all blades into the mold plate 8 to complete the entire die preparation work. This preparation work is faster and more efficient than existing technologies, eliminating the need for repeated hammering for blade installation, significantly reducing time and improving work efficiency.

[0039] like Figures 7 to 9As shown, at least two magnets 705 are fixedly connected to the bottom of the mold body 1, and a stamping mechanism 7 is fixedly connected to the top of the mold body 1. The stamping mechanism 7 includes a bracket 703, a hydraulic press 701 is fixedly connected to the top and bottom surfaces of the bracket 703, and a stamping plate 702 is fixedly connected to the bottom of the hydraulic press 701. At least two electromagnets 704 are fixedly connected to the center of the bottom surface of the stamping plate 702. The outer surface of the magnets 705 is flush with the bottom surface of the mold body 1, and the bottom surface of the electromagnets 704 is flush with the bottom surface of the stamping plate 702. The magnets 705 have opposite magnetic poles. After the preparation of the blade and die is completed, the die generally needs to be installed at the bottom of the output end of the stamping machine. In the prior art, the distance between the bottom of the output end and the stamping platform is generally limited, and the installation position is at the top surface of the internal space. Under these conditions, the accuracy of installation is greatly difficult. In the prior art, it is generally done by manually applying an adhesive such as double-sided tape and then placing it on the platform with the adhesive facing down. The die is fixed on the stamping machine output end by pressing the output end of the press. However, this method is not only inaccurate but also inconvenient to disassemble. In this invention, the cooperation between electromagnet 704 and magnet 705 is used to solve this problem. The bracket 703 is a bracket with a top plate. The hydraulic press 701 on the bottom surface of the top plate can drive the stamping plate 702 to press down. At least two electromagnets 704 on the bottom surface of the stamping plate 702 are electromagnets with opposite poles. This design mainly utilizes the advantages of position limitation and adjustable attraction between two points. During the installation process, no adhesive is needed to accurately install the die body 1 on the bottom of the stamping plate 702. Due to the effect of opposite poles, the direction of the die body 1 is determined. Since like poles repel each other, there will be no situation where the direction is opposite. At the same time, the attraction of the electromagnet can be adjusted, which is very convenient for installation and disassembly, greatly reducing the installation and disassembly time, and does not affect the normal stamping operation.

[0040] like Figures 1 to 9As shown, a torque gearbox 206 is fixedly connected to the inner wall of the clamping plate 203. A rotating convex plate 205 is fixedly connected to the output end of the torque gearbox 206. A chamfered bevel is formed on the inner top side of the clamping plate 203. A concave space is formed on the bottom surface of the sliding table 201. The sliding table 201 is slidably connected to the bottom slide rail of the mold body 1. A micro motor is installed inside the sliding table 201. Its output end is meshed with the rotating end of the torque gearbox 206 through a transmission component. A battery and controller are provided on the side of the micro motor. The micro motor can be selected as a 4x8 mm motor. The hollow cup servo motor is used in the stamping process. If the position of the blade 6 is offset, or the carbonized layer falls off and the blade 6 needs to be replaced, or the stamping platform needs to be tidied, the tidying mechanism 5 can be used. When the blade 6 needs to be disassembled, the controller controls the rotation of the miniature hollow cup servo motor inside the sliding table 201. This type of motor is inexpensive and extremely small in size. It is commonly used in robot fingers and micro drones and is already widely used. The motor works by driving the top torque gearbox 206 and the rotating cam 205 to rotate through the gear assembly. The rotation of the rotating cam 205 will push the blade 6 out.

[0041] like Figures 1 to 9 As shown, a sorting mechanism 5 is fixedly connected to the bottom end of the stamping mechanism 7. The sorting mechanism 5 includes two side supports 501. A servo motor 502 is fixedly connected to the inner side of the side supports 501. A sorting platform 503 is fixedly connected to the inner rotating end of the servo motor 502. A recycling box 504 is slidably connected to the side end of the sorting platform 503. As the blade 6 is ejected, it falls and, using the telescopic rod structure between the hydraulic cylinder 304 and the mold body 1, in conjunction with the rotation of the rotating plate 302 and the lifting plate 303, tilts the lower pressure plate 301, causing the blade 6 to slide onto the sorting platform 503. Due to the imbalance of gravity, the sorting platform 503 tilts under the action of the servo motor 502 and the side supports 501, thus tilting the blade... The piece 6 moves to the recycling bin 504 via an inclined plane. The servo motor 502 can control its rotation. When the electromagnetic force weakens, the press extends and places the mold body 1 on the top surface of the sorting platform 503. The rotation of the servo motor 502 completes the recycling of the mold body 1. If there are some materials on the table that need to be cleaned, they can also be sorted and recycled using the servo motor 502, the sorting platform 503, and the recycling bin 504 to keep the table clean. The bottom of the bracket 703 is fixedly connected to two fixed support components and two controllable telescopic support components. At the same time, during the stamping process, the fixed support components and controllable telescopic support components of the bracket 703 can be used to support the sorting platform 503 without affecting the rotation of the sorting platform 503.
