Description

Technical Field

[0001] This utility model relates to the field of die-cutting blade splicing technology, and in particular to a seamless splicing structure for the ends of die-cutting blades. Background Art

[0002] A die-cutting plate is a device that splices multiple blades into a specific pattern. It is used to cut printed materials or boards into specific shapes. When splicing several blades, in order to ensure the cutting quality, a seamless splicing structure is required to make the ends of the multiple blades fit together.

[0003] Patent specification CN211590443U discloses a die-cutting blade end splicing structure, including: a substrate, a first cutting groove on the substrate, a second cutting groove connected to the first cutting groove, a mounting groove at the connection between the first and second cutting grooves, a first blade disposed in the first cutting groove, a second blade disposed in the second cutting groove, and a connecting device embedded in the mounting groove for connecting the first and second blades. The connection between the first and second blades can be snapped into the connecting device for detachable fixing. This utility model uses a connecting structure to replace traditional welding. During blade assembly, adjacent blades are fixed directly by inserting a locking block into the mounting groove, which is convenient and quick, improving production efficiency, splicing quality, and safety.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned die-cutting blade end splicing structure: the device makes the ends of the first blade and the second blade seamlessly spliced ​​by placing the first locking block at the bottom of the first blade and the second locking block at the bottom of the second blade into the positioning groove, and splices the connection between several blades together by positioning grooves in several bases. Since the distance between two adjacent positioning grooves is fixed, when changing blades of different lengths, the two locking blocks in the same blade cannot be placed into the two positioning grooves at the same time, which makes the device only able to splice blades of a specific length, reducing the applicability of the device. In view of this, a seamless splicing structure for the end of the die-cutting blade is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seamless splicing structure for the ends of die-cutting blades.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a seamless splicing structure for the end of a die-cutting plate blade, comprising a fixing plate, a blade groove at the top of the fixing plate, two cutting blades inside the blade groove, two locking blocks fixed at the bottom of each of the two cutting blades, a placement groove at the top of the fixing plate, a base inside the placement groove, a positioning groove at the top of the base, two sliding rods slidably connected inside the base, two fixing seats fixed on the sides of each of the two sliding rods, a plurality of screws threadedly connected inside each of the four fixing seats, the sides of the plurality of screws threadedly connected to the inside of the fixing plate, two limiting blocks fixedly provided at the top of the base, and limiting bolts inside each of the two limiting blocks.

[0007] As a further description of the above technical solution: the inside of the positioning groove fits into one side of two of the locking blocks, and the inside of the positioning groove is provided with two stops, so that the positioning groove can limit the locking blocks.

[0008] As a further description of the above technical solution: each of the two limiting blocks has a first limiting hole inside, and the interior of the two first limiting holes is threadedly connected to the side of the two limiting bolts respectively, so that the limiting bolts can limit the limiting blocks.

[0009] As a further description of the above technical solution: the top of the fixing plate is provided with several second limiting holes, and the sides of the two limiting bolts are respectively connected to the internal threads of the corresponding two second limiting holes, so that the fixing plate can limit the cutting blade.

[0010] As a further description of the above technical solution: the fixed plate has four connecting slots inside, and each of the four connecting slots is provided with a clamping plate, which facilitates clamping the cutting blade.

[0011] As a further description of the above technical solution: a pair of movable rods are fixedly provided on one side of each of the four clamping plates, and a movable plate is provided at one end of each of the four pairs of movable rods. Eight movable slots are opened inside the fixed plate, and the interior of each of the eight movable slots is respectively in contact with the side of the eight movable rods. The movable plate facilitates the movement of the movable rods.

[0012] As a further description of the above technical solution: one side of each of the four movable plates is fixedly connected to one end of each of the four pairs of moving rods, and each of the four movable plates has a positioning hole inside, and each of the four positioning holes has a fixing bolt inside, which facilitates the limiting of the movable plates.

[0013] As a further description of the above technical solution: the fixing plate has four threaded holes inside, and the interior of the four threaded holes is respectively threaded to the side of the four fixing bolts.

[0014] This utility model has the following beneficial effects:

[0015] This utility model designs a seamless splicing structure for the ends of die-cutting blades. Through its design, when it is necessary to change cutting blades of different lengths, the left and right moving limit blocks move the base left and right, thereby adjusting the distance between the positioning grooves of two adjacent bases. When the distance between the positioning grooves of two adjacent bases reaches the required length, the limit bolts are placed into the limit blocks and the corresponding second limit holes, thereby limiting the base and preventing it from moving. The four locking blocks at the connection points of the three cutting blades are respectively placed into the positioning grooves of the two bases, so that the ends of the three cutting blades are seamlessly spliced. This makes it easy to move the positioning grooves in the base, and the distance between the positioning grooves is adjustable. This makes it easy to stably limit the cutting blades of different lengths, thus improving the applicability of the device.

[0016] This utility model designs a seamless splicing structure for the ends of die-cutting blades. Through its design and coordination, when two cutting blades are placed in the blade slot, rotating the fixing bolt causes the movable plate to move closer to the fixed plate, which in turn moves the moving rods closer together, thereby causing the clamping plates to move closer together. The clamping plates hold the cutting blades, further improving the stability of the cutting blades when placed. When the cutting blades are thicker, reversing the fixing bolt causes the movable plate to loosen, pulling it away from the fixed plate. This causes the moving rods to move away from each other, which in turn moves the clamping plates away from each other, increasing the distance between the two clamping plates. This allows for the clamping of thicker cutting blades, making the device easy to stably hold cutting blades of different thicknesses and further improving the applicability of the device.

[0023] Reference Figures 1-4 This utility model provides a seamless splicing structure for the ends of die-cutting blades: It includes a fixing plate 1, with a blade groove at the top of the fixing plate 1. Two cutting blades 2 are housed inside the blade groove, and two locking blocks 3 are fixed to the bottom of each of the two cutting blades 2. A placement groove 15 is provided at the top of the fixing plate 1, facilitating the movement of a base 4. The base 4 is housed inside the placement groove 15, and a positioning groove 16 is provided at the top of the base 4. By inserting adjacent locking blocks 3 into the positioning groove 16 within the base 4, the ends of the two cutting blades 2 can be easily joined together. The base 4 has two sliding rods 5 inside, which are convenient for limiting the base 4 and preventing it from moving out of the placement slot 15. Two fixing seats 6 are fixed on the sides of the two sliding rods 5, which are convenient for limiting the sliding rods 5. Several screws 7 are threaded inside the four fixing seats 6, which are convenient for fixing the fixing seats 6 to the fixing plate 1. The sides of the screws 7 are threaded to the inside of the fixing plate 1. Two limiting blocks 8 are fixed on the top of the base 4, and limiting bolts 9 are provided inside the two limiting blocks 8.

[0024] As a further implementation of the above technical solution: the inside of the positioning groove 16 is in contact with one side of two of the locking blocks 3, and the inside of the positioning groove 16 is provided with two stops 10, so that the positioning groove 16 can limit the locking blocks 3.

[0025] As a further implementation of the above technical solution: each of the two limiting blocks 8 has a first limiting hole inside, and the inside of the two first limiting holes is threadedly connected to the side of the two limiting bolts 9 respectively, so that the limiting bolts 9 can limit the limiting blocks 8.

[0026] As a further implementation of the above technical solution: the top of the fixing plate 1 is provided with several second limiting holes, and the sides of the two limiting bolts 9 are respectively connected to the internal threads of the corresponding two second limiting holes, so that the fixing plate 1 can limit the cutting blade 2.

[0027] In specific implementation: Two cutting blades 2 are joined together, so that the two locking blocks 3 at the joint of the two cutting blades 2 enter the positioning groove 16 of the base 4 together. The cutting blades 2 enter the blade groove. The width of the positioning groove 16 is slightly larger than the width of the two locking blocks 3. A stop block 10 is inserted into the gap between the base 4 and the locking blocks 3 to prevent the locking blocks 3 from loosening with the cutting blades 2, thus ensuring a seamless splicing at the ends of the two cutting blades 2. A base 4 and positioning groove 16 are provided at the connection point between every two cutting blades 2, ensuring a seamless splicing at the end connections between multiple cutting blades 2. When installing the base 4, it is placed into the placement groove 15, so that the four fixing seats 6 are in contact with the sides of the placement groove 15. Several screws 7 are used to fix the fixing seats 6 to the placement groove 15, thus limiting the base 4 to be confined by the placement groove 15 and the sliding rod 5, allowing it to move only left and right, preventing… The base 4 detaches from the placement slot 15. When it is necessary to replace the cutting blade 2 of different lengths, the left and right limiting block 8 is moved, thereby driving the base 4 to move left and right. This allows adjacent bases 4 to move closer and further apart, making the spacing between the positioning slots 16 of the two adjacent bases 4 adjustable. When the spacing between the positioning slots 16 of the two adjacent bases 4 reaches the required length, the limiting bolt 9 is placed into the limiting block 8 and the corresponding second limiting hole, thereby limiting the base 4 and preventing it from moving. The four locking blocks 3 at the connection of the three cutting blades 2 are respectively placed into the positioning slots 16 of the two bases 4, so that the ends of the three cutting blades 2 are seamlessly spliced. This makes it easy to move the positioning slots 16 in the base 4, and the spacing between the positioning slots 16 is adjustable. This makes it easy for the device to stably limit the cutting blades 2 of different lengths, improving the applicability of the device.

[0028] As a further implementation of the above technical solution: the fixed plate 1 has four connecting slots inside, and each of the four connecting slots is provided with a clamping plate 11, which is convenient for clamping the cutting blade 2.

[0029] As a further implementation of the above technical solution: a pair of movable rods 12 are fixedly provided on one side of each of the four clamping plates 11, and a movable plate 13 is provided at one end of each of the four pairs of movable rods 12. Eight movable slots are opened inside the fixed plate 1, and the interior of the eight movable slots is respectively attached to the side of the eight movable rods 12. The movable plate 13 facilitates the movement of the movable rods 12.

[0030] As a further implementation of the above technical solution: one side of each of the four movable plates 13 is fixedly connected to one end of each of the four pairs of moving rods 12. Each of the four movable plates 13 has a positioning hole inside, and each of the four positioning holes has a fixing bolt 14 inside. The fixing bolt 14 is used to limit the movement of the movable plates 13.

[0031] As a further implementation of the above technical solution: the fixing plate 1 has four threaded holes inside, and the inside of the four threaded holes is respectively threaded to the side of the four fixing bolts 14.

[0032] In specific implementation: After the two cutting blades 2 are placed in the blade slot, the fixing bolt 14 is rotated so that it enters the fixing plate 1, thereby bringing the movable plate 13 closer to the fixing plate 1. This causes the moving rods 12 to move closer together, which in turn causes the clamping plates 11 to move closer together. The clamping plates 11 hold the cutting blades 2, further improving the stability of the cutting blades 2 when placed. When the cutting blades 2 are thicker, the fixing bolt 14 is reversed so that the movable plate 13 is loosened. The movable plate 13 is pulled away from the fixing plate 1, thereby causing the moving rods 12 to move away from each other, which in turn causes the clamping plates 11 to move away from each other. This increases the distance between the two clamping plates 11, allowing for the clamping of thicker cutting blades 2. This makes the device easier to stably clamp cutting blades 2 of different thicknesses, further improving the applicability of the device.
