[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a cutting apparatus for card printing. (See also...) Figure 1-6 A card printing cutting device includes a worktable 1, a first support frame 2 and a pressing structure 3 installed on the end face of the worktable 1 and on the front and rear sides, an electric telescopic rod 4 installed on the end face of the first support frame 2, a blade changing structure 5 installed on the drive end of the electric telescopic rod 4 and in the inner cavity of the first support frame 2, and a cutting blade 6 installed on the blade changing structure 5.

[0028] The blade changing structure 5 includes a fixed block 51 installed on the drive end of the electric telescopic rod 4. Limiting blocks 52 are slidably installed on the left and right sides of the fixed block 51 via sliding grooves 511. Crossbars 53 are symmetrically installed on the corresponding side walls of the two sets of limiting blocks 52. An installation ring 54 is installed on the outer wall of the crossbar 53. A spring 55 is installed on the installation ring 54 on the outer wall of the crossbar 53. A pull plate 56 is installed on the front of the left opening 61. By using the fixed block 51, the installation groove 512, the limiting block 52, the installation ring 54, and the spring 55 in cooperation, the quick replacement function of the cutting blade 6 is realized. This solves the problem that most cutting blades of existing card printing cutting devices are fixedly installed on the device, and the cutting blades will wear out after long-term card cutting operations. The fixed cutting blades are very inconvenient to replace. This reduces the replacement time of the cutting blade 6 and improves the replacement efficiency of the cutting blade 6.

[0029] Reference Figure 1 , Figure 2 and Figure 4The clamping structure 3 includes a second support frame 31 installed on the end face of the workbench 1. A servo motor 32 and two sets of slide rails 33 are installed on the left side wall of the second support frame 31. A screw 34 is installed on the drive end of the servo motor 32. A threaded sleeve 35 corresponding to the slide rail 33 is threadedly installed on the screw 34. Connecting rods 36 are rotatably installed on the front and rear sides of the threaded sleeve 35. A T-shaped plate 38 is slidably installed in the inner cavity of the slide rail 33. A connecting block 37 is installed on the side wall of the T-shaped plate 38. The lower ends of the two sets of T-shaped plates 38 are connected by a pressure plate 39. Connection; a support leg 7 is installed at the bottom of the workbench 1 and at the corner. A cutting groove 11 is opened on the end face of the workbench 1 and corresponding to the cutting blade 6. A vertical rod 8 is symmetrically installed on the end face of the fixing block 51. The first support frame 2 is slidably connected to the vertical rod 8 through the connecting hole. An installation groove 512 is opened on the fixing block 51 and corresponding to the installation ring 54. The fixing block 51 is connected to the end of the spring 55 away from the installation ring 54 through the installation groove 512. A tool groove 513 is opened on the lower side of the fixing block 51. The fixing block 51 is slidably connected to the cutting blade 6 through the tool groove 513.

[0030] Among them, by setting the vertical rod 8, when the electric telescopic rod 4 drives the tool changing structure 5 and the cutting blade 6 to move up and down, the movement of the tool changing structure 5 and the cutting blade 6 is more stable.

[0031] Reference Figure 1 , Figure 3 Figure 4 The cutting blade 6 has openings 61 on both the left and right sides, and a limiting groove 62 adapted to the limiting block 52 is provided on the opening 61. The limiting groove 62 is located on the right side of the opening 61. A fixing plate 57 is installed on the front of the opening 61. The fixing plate 57 is installed with a limiting bolt 58 through the connecting hole. A threaded hole 561 is provided on the pull plate 56 corresponding to the limiting bolt 58.

[0032] Among them, by setting the limiting bolt 58 and the threaded hole 561, when the limiting bolt 58 and the threaded hole 561 are threadedly engaged, the pull plate 56 is fixed on the fixing plate 57, so that the two sets of limiting blocks 52 will not move, thereby achieving a firm installation of the cutting blade 6 and making the installation stability of the cutting blade 6 stronger.

[0033] Reference Figure 5 and Figure 6The slide rail 33 has a through hole 331 corresponding to the screw 34. The end of the second support frame 31 away from the servo motor 32 passes through two sets of through holes 331 in sequence and is rotatably connected to the right side of the second support frame 31 through a bearing. The front and rear side walls of the threaded sleeve 35 are equipped with a first connecting pin 351 that is rotatably connected to the connecting rod 36. The front and rear side walls of the connecting block 37 are equipped with a second connecting pin 371. The end of the connecting rod 36 away from the first connecting pin 351 is rotatably connected to the outer wall of the second connecting pin 371 through a connecting hole. The other ends of the first connecting pin 351 and the second connecting pin 371 are equipped with limit pieces 310.

[0034] The limiting piece 310 ensures that both ends of the connecting rod 36 are stably connected to the outer walls of the first connecting pin 351 and the second connecting pin 371, preventing disconnection and ensuring the stable operation of the pressing structure 3.

[0035] Working principle: Remove the limiting bolt 58 from the pull plate 56 and move the pull plate 56 away from the fixed plate 57. The pull plate 56 moves the left limiting block 52 along with it. Through the connection of the spring 55, the left limiting block 52 moves synchronously from the corresponding limiting groove 62 to the opening 61 along with the right limiting block 52. At this time, the mounting ring 54 compresses the spring 55, and the old cutting blade 6 can be moved downward from the tool groove 513. Then, a new cutting blade 6 is replaced, and the cutting blade 6 is driven upward into the tool groove 513. The limiting block 52 slides from the opening 61, so that the limiting block 52 reaches the bottom of the opening 61. Then, the pull plate 56 is released, and the spring... Under the reset action of 55, spring 55 drives the mounting ring 54 to move in the opposite direction. The mounting ring 54 drives the two sets of limit blocks 52 to slide into the limit groove 62, thereby fixing the cutting blade 6 and realizing the quick replacement function of the cutting blade 6. It can drive the limit bolt 58 into the threaded hole 561, increasing the installation stability of the cutting blade 6. This solves the problem that most cutting blades of existing card printing cutting devices are fixedly installed on the device, and the cutting blades will wear out after long-term card cutting operations. The fixed cutting blades are very inconvenient to replace. This reduces the replacement time of the cutting blade 6 and improves the replacement efficiency of the cutting blade 6.

[0036] The entire uncut card is passed under the pressure plate 39 and the cutting position is moved to below the cutting blade 6, aligning the blade of the cutting blade 6 with the cutting line of the card. The servo motor 32 is started to rotate forward by the control switch. The servo motor 32 drives the screw 34 to rotate on the second support frame 31. The screw 34 moves the two sets of threaded sleeves 35 to the right in sync. The threaded sleeves 35 drive the connecting rod 36 to move downward to the right through the transmission action of the first connecting pin 351. The connecting rod 36 drives the connecting block 37 to slide downward in the slide rail 33 through the transmission action of the second connecting pin 371. The two sets of connecting blocks 37 drive the pressure plate 39 to move down and press the card to fix it, so that the card will not move during the cutting process. This solves the problem that the existing card printing cutting device lacks a card fixing structure, which causes the card to move during the cutting process and results in poor card cutting effect. It prevents the card from being cut incorrectly due to card movement during the cutting process and improves the card cutting effect.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
