Technical Field
[0001] This utility model relates to the field of die-cutting machine technology, specifically to a die-cutting mechanism for a printing slotting die-cutting machine. Background Technology
[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. They utilize steel blades, metal molds, and steel wire, applying pressure through a printing plate to cut printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing. Die-cutting machines have an internal die-cutting mechanism capable of die-cutting printed materials.
[0003] In the process of printing and slotting cardboard, a die-cutting mechanism of a printing and slotting die-cutting machine is required.

This mechanism includes a die-cutting machine body, a supporting frame at the bottom of the machine body, a collecting device inside the machine body, and a die-cutting device inside the machine body. This invention uses a starting motor to drive the upper and lower die-cutting cutters to rotate through a series of transmissions, without directly driving the die-cutting cutters to rotate, thus avoiding wear on the cutters and driving components and extending their service life.
[0004] However, the die-cutting mechanism of the printing slotting die-cutting machine of this utility model uses die-cutting blades with a fixed spacing, which cannot adjust the spacing according to different printing needs, resulting in poor processing flexibility and failure to meet production requirements. Therefore, a die-cutting mechanism for a printing slotting die-cutting machine is proposed to solve the problems mentioned above. Utility Model Content

It solves the problem that the existing die-cutting mechanisms of printing slotting die-cutting machines use die-cutting blades with fixed spacing, which cannot adjust the spacing according to different printing needs, resulting in poor processing flexibility and inability to meet production requirements.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a die-cutting mechanism for a printing slotting die-cutting machine, comprising a die-cutting machine body and a controller fixedly installed outside the die-cutting machine body, wherein a die-cutting mechanism extending into the die-cutting machine body is provided outside the die-cutting machine body, and a spacing adjustment mechanism is provided inside the die-cutting machine body;
[0007] The die-cutting mechanism includes a first die-cutting roller rotatably connected inside the die-cutting machine body, a die-cutting blade sleeved outside the first die-cutting roller, a second die-cutting roller rotatably connected inside the die-cutting machine body, and a drive mechanism disposed outside the die-cutting machine body.

[0009] Furthermore, a fixed cylinder is fixedly connected to the outside of the die-cutting blade, and the fixed cylinder is slidably sleeved with the surface of the first die-cutting roller, and an elastic abutment rod is slidably sleeved on the inner wall of the fixed cylinder.
[0010] Furthermore, the drive mechanism includes driven wheels fixedly installed at one end of the first die-cutting roller and the second die-cutting roller respectively, a belt connecting the two driven wheels, and a drive motor fixedly installed outside the die-cutting machine body. The output shaft of the drive motor is fixedly connected to one end of the first die-cutting roller.
[0011] Furthermore, two guide rods are fixedly connected between the two fixed plates, and several movable blocks are slidably connected to the outside of the guide rods at equal intervals.
[0012] Furthermore, a pulley extending into the variable pitch groove is fixedly connected to the back of the movable block. The outer diameter of the pulley is adapted to the inner diameter of the variable pitch groove, and the variable pitch groove and the pulley are slidably connected.
[0013] Furthermore, the adjustment mechanism includes a fixed frame fixedly installed outside the movable block, an electric push rod fixedly installed on the upper surface of the fixed frame, a movable plate fixedly connected to the output end of the electric push rod, and an adjustment clamp fixedly installed outside the movable plate.

The cleaning mechanism includes a blower fixedly installed on the top of the die-cutting machine body, a collection box slidably connected to the inside of the die-cutting machine body, and an air duct fixedly connected between the blower and the die-cutting machine body.
[0015] Compared with the prior art, this utility model provides a die-cutting mechanism for a printing slotting die-cutting machine, which has the following beneficial effects:
[0016] 1. The die-cutting mechanism of this printing slotting die-cutting machine is driven by a reciprocating motor starting the controller to rotate the adjusting roller. Since the adjusting roller has a variable pitch groove inside, the moving block that cooperates with the variable pitch groove will move when the adjusting roller rotates. Through the extension and retraction of the electric push rod, the position of the moving plate and the adjusting clamp can be precisely controlled, so that the clamp contacts the elastic abutment rod to release the locking of the die-cutting blade, thereby realizing the precise adjustment of the die-cutting blade spacing, greatly improving the adjustment flexibility and achieving the advantage of high processing flexibility.
[0017] 2. The die-cutting mechanism of this printing slotting die-cutting machine starts the blower through the controller and blows air into the die-cutting machine body through the air duct.

Detailed Implementation
[0023] 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 protection scope of the present utility model.
[0024] Please see Figures 1 to 4 The die-cutting mechanism of a printing slotting die-cutting machine in this embodiment includes a die-cutting machine body 1 and a controller 2 fixedly installed outside the die-cutting machine body 1. The die-cutting machine body 1 is provided with a die-cutting mechanism 3 extending into it, and the die-cutting machine body 1 is provided with a spacing adjustment mechanism 4. The die-cutting mechanism 3 includes a first die-cutting roller 31 rotatably connected inside the die-cutting machine body 1, a die-cutting blade 32 sleeved outside the first die-cutting roller 31, a second die-cutting roller 33 rotatably connected inside the die-cutting machine body 1, and a drive mechanism provided outside the die-cutting machine body 1.
[0025] The die-cutting blade 32 is externally fixedly connected to a fixed cylinder, and the fixed cylinder is slidably sleeved with the surface of the first die-cutting roller 31. An elastic abutment rod is slidably sleeved on the inner wall of the fixed cylinder.
[0026] Specifically, the drive mechanism includes driven wheels 34 fixedly mounted at one end of the first die-cutting roller 31 and the second die-cutting roller 33, a belt 35 drivingly connected between the two driven wheels 34, and a drive motor 36 fixedly mounted outside the die-cutting machine body 1. The output shaft of the drive motor 36 is fixedly connected to one end of the first die-cutting roller 31. The drive motor 36 drives the first die-cutting roller 31 and the second die-cutting roller 33 to rotate simultaneously through the belt 35 and the driven wheels 34. This transmission method ensures the synchronous rotation of the two die-cutting rollers and avoids die-cutting errors caused by inconsistent speeds.
[0027] In this embodiment, the spacing adjustment mechanism 4 includes a mounting base 41 fixedly connected to the inner wall of the die-cutting machine body 1, a fixing plate 42 fixedly installed on the left and right sides of the mounting base 41, a reciprocating motor 43 fixedly installed outside the right fixing plate 42, an adjusting roller 44 fixedly installed on the output shaft of the reciprocating motor 43, a pitch groove 45 opened inside the adjusting roller 44, a moving block 47 slidably connected inside the mounting base 41, and an adjustment mechanism provided outside the mounting base 41.
[0028] Two guide rods 46 are fixedly connected between the two fixed plates 42. Several moving blocks 47 are slidably connected to the outside of the guide rods 46 at equal intervals. The controller 2 starts the reciprocating motor 43 to drive the adjusting roller 44 to rotate. Since the adjusting roller 44 has a pitch groove 45 inside, the moving blocks 47 that cooperate with the pitch groove 45 move accordingly when the adjusting roller 44 rotates. Through the extension and retraction of the electric push rod 410, the positions of the moving plate 411 and the adjusting clamping plate 412 can be precisely controlled, causing the clamping plate to contact the elastic abutment rod and release the locking of the die-cutting blade 32. This achieves precise adjustment of the spacing of the die-cutting blade 32, greatly improving the flexibility of adjustment and achieving the advantage of high processing flexibility.
[0029] Specifically, the back of the movable block 47 is fixedly connected to a pulley 48 extending into the variable pitch groove 45. The outer diameter of the pulley 48 is adapted to the inner diameter of the variable pitch groove 45, and the variable pitch groove 45 and the pulley 48 are slidably connected.
[0030] It should be noted that the adjustment mechanism includes a fixed frame 49 fixedly installed on the outside of the movable block 47, an electric push rod 410 fixedly installed on the upper surface of the fixed frame 49, a movable plate 411 fixedly connected to the output end of the electric push rod 410, and an adjustment clamp 412 fixedly installed on the outside of the movable plate 411. A guide rail 413 is fixedly installed on the outside of the movable block 47, and the movable plate 411 is slidably connected to the outside of the guide rail 413.
[0031] In this embodiment, a cleaning mechanism 5 extending into the upper surface of the die-cutting machine body 1 is provided. The cleaning mechanism 5 includes a blower 51 fixedly installed on the top of the die-cutting machine body 1, a collection box 53 slidably connected inside the die-cutting machine body 1, and an air duct 52 fixedly connected between the blower 51 and the die-cutting machine body 1. The blower 51 is started by the controller 2, and airflow is blown into the die-cutting machine body 1 through the air duct 52. This airflow can effectively blow and pick up dust, debris, and other impurities inside the die-cutting machine body 1, so that the impurities can be captured by the collection box 53, thereby achieving rapid cleaning of the inside of the die-cutting machine body 1.
[0032] The working principle of the above embodiments is as follows:
[0033] In use, the controller 2 starts the reciprocating motor 43 to drive the adjusting roller 44 to rotate. Since the adjusting roller 44 has a variable pitch groove 45 inside, the moving block 47 that cooperates with the variable pitch groove 45 will move when the adjusting roller 44 rotates. Through the extension and retraction of the electric push rod 410, the position of the moving plate 411 and the adjusting clamp 412 can be precisely controlled, so that the clamp contacts the elastic abutment rod to release the locking of the die-cutting blade 32, thereby realizing the precise adjustment of the spacing of the die-cutting blade 32. The controller 2 starts the drive motor 36 to work, and through the transmission of the belt 35 and the driven wheel 34, it drives the first die-cutting roller 31 and the second die-cutting roller 33 to rotate simultaneously. The controller 2 starts the blower 51 to work, and blows air into the die-cutting machine body 1 through the air duct 52. This airflow can effectively blow and roll up the dust, debris and other impurities inside the die-cutting machine body 1, so that the impurities can be captured by the collection box 53, thereby realizing the rapid cleaning of the inside of the die-cutting machine body 1.
[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
