Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production, in particular to an adjustable die-cutting machine for producing cigarette boxes. Background Art

[0002] The adjustable die-cutting machine for the production of cigarette boxes is a device specially used for the production of cigarette boxes. This die-cutting machine has the characteristics of adjustability. It can flexibly adjust the position, angle, pressure and other parameters of the die-cutting tool according to the design requirements of cigarette boxes of different specifications. Through precise adjustment, it can adapt to the production needs of cigarette boxes of different sizes, shapes and materials, ensuring that the die-cut cigarette boxes have neat edges and accurate sizes.

[0003] At present, when the conventional adjustable die-cutting machine for producing cigarette boxes is used, the corresponding connection layer is first selected according to the shape of the cardboard to be cut, and the distance between the two positioning wheels is adjusted according to the size of the cardboard to be cut. Then, the cardboard is conveyed into the support plate through the conveying device, and then conveyed to the side of the die-cutting roller by the feeding roller. During this process, when the sensing positioning device senses the cardboard, the feeding roller continues to convey the cardboard, and the die-cutting roller rotates synchronously. When the cardboard passes through the die-cutting roller, it will be cut along the cutting line composed of blades arranged in sequence on the die-cutting roller;

[0004] However, when the conveying device is used to transport the cardboard, the cardboard is transported to the side of the die-cutting roller under the action of the feed roller. The feed roller generates friction with the cardboard through rotational motion to push it forward, but since the cardboard is wrapped around the surface of the feed roller, it will bend and deform, which will cause the cardboard to be uneven. When the uneven cardboard enters the die-cutting machine, it may contact the die-cutting tool unevenly, causing uneven die-cutting and even paper jams. This will frequently interrupt the production process and require operators to clean and adjust, wasting time and manpower. Summary of the invention

[0005] In order to solve the problem of the inconvenience of flattening the cardboard mentioned in the above background technology, the present invention provides an adjustable die-cutting machine for producing cigarette boxes.

[0006] To achieve the above object, the present invention provides the following technical solution: an adjustable die-cutting machine for producing cigarette boxes, comprising a fixed frame, a conveyor belt is fixedly installed inside the fixed frame, a cutting mechanism, a flattening mechanism and a guide mechanism are sequentially designed on the top of the fixed frame from left to right, the flattening mechanism is fixedly installed on one side of the cutting mechanism, and a tensioning mechanism is installed at the bottom of the guide mechanism;

[0007] The leveling mechanism comprises a fixed frame, a slide rail, a slider and a leveling roller, wherein the slide rail is fixedly connected to one end of the fixed frame, the slider is slidably connected to the inside of the slide rail, and one side of the slider is connected to the leveling roller through a support frame;

[0008] The tensioning mechanism includes two moving plates slidably connected to both sides of the fixing frame, a gear meshed with the moving plate, and a driving motor fixedly connected to the gear, and the two moving plates are connected by an adjustment plate.

[0009] Preferably, the bottom surface of the fixing frame is arranged in a rectangular array with four supporting legs, and the bottom surfaces of the four supporting legs are fixedly connected to the bottom of the fixing frame, and slide grooves are provided with movable plates on both sides of the fixing frame.

[0010] Preferably, the cutting mechanism includes an electric guide rail, an electric skateboard, a telescopic rod and a cutting knife. The electric skateboard is slidably connected to the electric guide rail, the bottom surface of the electric skateboard is fixedly connected to the top surface of the telescopic rod through a connecting frame, and the cutting knife is fixedly connected to the bottom surface of the telescopic rod.

[0011] Preferably, both ends of the electric guide rail are fixedly connected with fixed plates, a top plate is fixedly installed on the top of the fixed plate, the bottom surface of the fixed plate is connected to the top surface of the fixed frame, and a short plate is fixedly connected to the surface of the telescopic rod close to the cutting knife end.

[0012] Preferably, the other end of the fixing frame is fixedly connected to one side of the top plate, the other side of the sliding block is fixedly connected to one end of the short plate, and both ends of the leveling roller are rotatably connected to the inner side of the supporting frame through a rotating shaft.

[0013] Preferably, the guide mechanism includes a limit block slidably connected to the top surface of the fixed frame, a fixed column fixedly connected to the top surface of the limit block, a fixed block fixedly installed on the top of the fixed column, and a first guide roller rotatably connected to one side of the fixed block.

[0014] Preferably, one end of the fixed block is fixedly connected to a continuation plate, one side of the continuation plate is rotatably connected to a second guide roller, and the other side of the fixed block is fixedly connected to an inclined plate, one end of which is connected to the movable plate.

[0015] Preferably, a long plate is fixedly connected to one side of the movable plate, the long plate is slidably connected to the inside of the slide groove, and the driving motor is fixedly installed inside one side of the fixed frame.

[0016] Preferably, the adjustment plate comprises a vertical plate and a round rod, and there are two vertical plates, and opposite sides of the two vertical plates are fixedly connected to one end of the round rod.

[0017] Preferably, a mounting frame is fixedly mounted on one end of the fixed frame close to the guide mechanism, and bases are fixedly connected to both sides of the interior of the mounting frame. There are two bases, and a feed roller is rotatably connected between the two bases.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention can flatten the bent cardboard by arranging the cooperation of the cutting mechanism and the flattening mechanism. Since the short plate fixedly connected to the surface of one end of the telescopic rod of the cutting mechanism close to the cutting knife is fixedly connected to the other side of the slider in the flattening mechanism, when the cutting mechanism is working, it will drive the slider to slide in the slide rail, and the slider is connected to the flattening roller through the support frame. The sliding of the slider drives the flattening roller to move, and the flattening roller flattens the cardboard to ensure that the surface of the cardboard is flat, avoiding the subsequent processing being affected by the unevenness. After the cardboard is flattened by the flattening mechanism, the probability of paper jam is greatly reduced, making the production process smoother, and reducing the time and manpower wasted on dealing with problems such as paper jam. The cooperation of the cutting mechanism and the flattening mechanism enables the cardboard to be effectively flattened before cutting, avoiding the need for additional correction procedures after cutting due to the unevenness of the cardboard, which simplifies the production process and improves the overall production efficiency.

[0020] The present invention facilitates the adjustment of the tension of the guide mechanism through the design of the guide mechanism and the tensioning mechanism, thereby adjusting the tension of the paper. When the cardboard needs to maintain a certain tension during the transmission process, the driving motor is started to drive the gear to rotate, and the moving plate meshing with the gear slides in the slide grooves on both sides of the fixed frame. The two moving plates are connected by an adjustment plate. The vertical plate and the round rod of the adjustment plate ensure that the two moving plates move synchronously. The long plate on one side of the moving plate slides in the slide groove to ensure the stability of the movement. The tension of the cardboard is adjusted by the movement of the moving plate to ensure that the cardboard is stably transmitted during the entire processing process. The appropriate tension can ensure that the cardboard remains stable during the transmission process without shaking or loosening. In this way, when the cutting mechanism is cutting, the cut edges can be neat and the size is accurate, the cutting deviation caused by the loose cardboard is avoided, and the cutting quality of the product is improved.

[0030] The leveling mechanism 4 includes a fixed frame 41, a slide rail 42, a slider 43 and a leveling roller 44. The slide rail 42 is fixedly connected to one end of the fixed frame 41, the slider 43 is slidably connected to the inside of the slide rail 42, and one side of the slider 43 is connected to the leveling roller 44 through a support frame 45.

[0031] The tensioning mechanism 6 includes two moving plates 61 slidably connected to both sides of the fixed frame 1 , a gear 62 meshingly connected to the moving plates 61 , and a driving motor 63 fixedly connected to the gear 62 . The two moving plates 61 are connected via an adjustment plate 64 .

[0032] The above scheme is adopted: the fixed frame 1 serves as the main frame of the whole equipment, providing a foundation for installation and support of the conveyor belt 2, the cutting mechanism 3, the leveling mechanism 4, the guiding mechanism 5 and the tensioning mechanism 6. The conveyor belt 2 transports the cardboard to be processed from one end of the fixed frame 1 to the other end, thereby realizing automated material transmission and improving production efficiency.

[0033] like Figures 1 to 6As shown, the bottom surface of the fixed frame 1 is distributed with four supporting legs in a rectangular array, and the bottom surfaces of the four supporting legs are fixedly connected to the bottom of the fixed frame 1. Both sides of the fixed frame 1 are provided with sliding grooves adapted to the movable plate 61. The cutting mechanism 3 includes an electric guide rail 31, an electric slide plate 32, a telescopic rod 33 and a cutting knife 34. The electric slide plate 32 is slidably connected to the electric guide rail 31, and the bottom surface of the electric slide plate 32 is fixedly connected to the top surface of the telescopic rod 33 through a connecting frame 35. The cutting knife 34 is fixedly connected to the bottom surface of the telescopic rod 33. Both ends of the electric guide rail 31 are fixedly connected with a fixed plate 7, and a top plate is fixedly installed on the top of the fixed plate 7.

[0034] The above scheme is adopted: the electric guide rail 31 provides a moving track for the electric slide plate 32, so that the electric slide plate 32 can accurately adjust the position of the cutting knife 34 in the horizontal direction to meet the cutting needs of different sizes and shapes. The electric slide plate 32 slides on the electric guide rail 31, driving the connecting frame 35, the telescopic rod 33 and the cutting knife 34 to move, so as to realize the cutting operation of different positions of the cardboard. The telescopic rod 33 can adjust the height of the cutting knife 34 so as to perform flexible cutting operations according to cardboards of different thicknesses. The cutting knife 34 cuts the cardboard into the required shape and size. The fixed plate 7 and the top plate provide a stable installation foundation for the electric guide rail 31 to ensure the stability of the cutting mechanism 3 during operation. By setting the cooperation between the cutting mechanism 3 and the flattening mechanism 4, the bent cardboard can be flattened. Due to the telescopic rod 33 of the cutting mechanism 3 The short plate 36 fixedly connected to the surface near one end of the cutting knife 34 is fixedly connected to the other side of the slider 43 in the leveling mechanism 4. When the cutting mechanism 3 is working, it will drive the slider 43 to slide in the slide rail 42. The slider 43 is connected to the leveling roller 44 through the support frame 45. The sliding of the slider 43 drives the leveling roller 44 to move. The leveling roller 44 performs a leveling operation on the cardboard to ensure that the surface of the cardboard is flat and avoids affecting subsequent processing due to unevenness. After the cardboard is leveled by the leveling mechanism 4, the probability of paper jams is greatly reduced, making the production process smoother and reducing the time and manpower wasted on dealing with problems such as paper jams. The cooperation of the cutting mechanism 3 and the leveling mechanism 4 enables the cardboard to be effectively leveled before cutting, avoiding the need for additional correction procedures after cutting due to uneven cardboard, which simplifies the production process and improves the overall production efficiency.

[0035] like Figures 1 to 6As shown, the guide mechanism 5 includes a limit block 51 slidably connected to the top surface of the fixed frame 1, a fixed column 52 fixedly connected to the top surface of the limit block 51, a fixed block 53 fixedly installed on the top of the fixed column 52, and a first guide roller 54 rotatably connected to one side of the fixed block 53, one end of the fixed block 53 is fixedly connected to a continuation plate, one side of the continuation plate is rotatably connected to a second guide roller 55, the other side of the fixed block 53 is fixedly connected to an inclined plate 56, one end of the inclined plate 56 is connected to a movable plate 61, one side of the movable plate 61 is fixedly connected to a long plate 611, the long plate 611 is slidably connected to the inside of the slide groove, the driving motor 63 is fixedly installed inside one side of the fixed frame 1, the adjustment plate 64 includes a vertical plate and a round rod, the number of the vertical plates is provided with two, the opposite sides of the two vertical plates are fixedly connected to one end of the round rod, the end of the fixed frame 1 close to the guide mechanism 5 is fixedly installed with a mounting frame, both sides of the inside of the mounting frame are fixedly connected to bases, the number of the bases is provided with two, and a feeding roller 8 is rotatably connected between the two bases.

[0036] The above scheme is adopted: the first guide roller 54 performs preliminary guidance on the cardboard to ensure that the cardboard can enter the subsequent processing link in the correct direction, and the extension plate is connected to the second guide roller 55 to provide an installation basis for the second guide roller 55. The second guide roller 55 further guides the cardboard to ensure the stability and accuracy of the cardboard during the transportation process. Through the design of the guide mechanism 5 and the tensioning mechanism 6, it is convenient to adjust the tension of the guide mechanism 5, thereby adjusting the tension of the paper. When the cardboard needs to maintain a certain tension during the transportation process, the drive motor 63 is started to drive the gear 62 to rotate, and the moving plate meshing with the gear 62 is connected. 61 slides in the slide grooves on both sides of the fixed frame 1, and the two movable plates 61 are connected by the adjustment plate 64. The vertical plate and the round rod of the adjustment plate 64 ensure that the two movable plates 61 move synchronously. The long plate 611 on one side of the movable plate 61 slides in the slide groove to ensure the stability of movement. Through the movement of the movable plate 61, the tension of the cardboard is adjusted to ensure that the cardboard is stably transmitted during the entire processing process. The appropriate tension can ensure that the cardboard remains stable during the transmission process without shaking or loosening. In this way, when the cutting mechanism 3 is cutting, the cutting edges can be neat and the size is accurate, the cutting deviation caused by the loose cardboard is avoided, and the cutting quality of the product is improved.

[0037] The working principle and use process of the present invention: Check whether the various components of the equipment are firmly installed, ensure that the four supporting legs on the bottom of the fixed frame 1 stably support the entire equipment, and the slides on both sides of the fixed frame 1 and the internal conveyor belt 2 are in normal condition, and at the same time check whether the connection of the cutting mechanism 3, the leveling mechanism 4, the guiding mechanism 5 and the tensioning mechanism 6 is normal;

[0038] Wrap the cardboard around the surface of the feeding roller 8, then pass one end of the cardboard through the first guide roller 54 and the second guide roller 55, then place one end of the cardboard to be processed on the conveyor belt 2 inside the fixed frame 1, start the conveyor belt 2, and the cardboard moves from one end of the fixed frame 1 to the other end driven by the conveyor belt 2;

[0039] When the cardboard is being conveyed, it needs to maintain a certain tension. The drive motor 63 is started, driving the gear 62 to rotate, and the moving plate 61 meshing with the gear 62 slides in the slide grooves on both sides of the fixed frame 1. The two moving plates 61 are connected by the adjustment plate 64. The vertical plate and round rod of the adjustment plate 64 ensure that the two moving plates 61 move synchronously. The long plate 611 on one side of the moving plate 61 slides in the slide groove to ensure the stability of movement. The tension of the cardboard is adjusted by moving the moving plate 61 to ensure that the cardboard is stably conveyed during the entire processing process;

[0040] When the cardboard moves to the bottom of the cutting mechanism 3, the electric guide rail 31 starts, driving the electric slide 32 to slide on the electric guide rail 31, thereby adjusting the lateral position of the cutting knife 34. The telescopic rod 33 connected to the connecting frame 35 on the bottom of the electric slide 32 can adjust the height of the cutting knife 34 as needed, so that the cutting knife 34 can accurately cut the cardboard;

[0041] Since the short plate 36 fixedly connected to the surface of one end of the telescopic rod 33 of the cutting mechanism 3 near the cutting knife 34 is fixedly connected to the other side of the slider 43 in the leveling mechanism 4, when the cutting mechanism 3 is working, it will drive the slider 43 to slide in the slide rail 42, and the slider 43 is connected to the leveling roller 44 through the support frame 45. The sliding of the slider 43 drives the leveling roller 44 to move, and the leveling roller 44 performs a leveling operation on the cardboard to ensure that the surface of the cardboard is flat, avoiding affecting subsequent processing due to unevenness.
