Description

Technical Field

[0001] The utility model relates to the field of paper box printing, in particular to a paper box printing die-cutting machine. Background Art

[0002] The die-cutting machine is also called a die cutting machine, a cutting machine, or a CNC punching machine. It is mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste discharge of some corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, and steel wires to apply a certain amount of pressure through the stamping plate to cut printed products or cardboard into a certain shape.

[0003] A Chinese patent discloses a carton printing and die-cutting machine (authorization announcement number CN 216423813 U). The patented technology can solve the problem that when feeding materials into the printing and die-cutting machines on the market, workers usually put the cardboard in the right position by feeling, or use simple limiters to regularize the cardboard. This may cause the position of the cardboard to not correspond to the position of the printing roller and the cutter when the cardboard enters the printing and die-cutting machine, which will cause the pattern and shape of the processed cardboard product to deviate, resulting in quality problems of the finished product and unnecessary waste.

[0004] There is dust adhering to the existing cardboard. If it is printed directly, the pattern may be blurred, making the product substandard. Using a fan for dust removal may cause the dust to float everywhere and damage the internal structure of the die-cutting machine. Utility Model Content

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a carton printing die-cutting machine is provided, including a die-cutting machine body 1 and a feed port 2. The die-cutting machine body 1 is provided with a feed port 2 on the front end surface. A fixed fan 11 is arranged at the rear of the die-cutting machine body 1. A fixed cavity 12 is installed at the bottom of the fixed fan 11. A plurality of outer tubes 13 are installed on the front end surface of the fixed cavity 12. The outer tubes 13 extend into the die-cutting machine body 1. An inner tube 14 is installed on the inner wall of the outer tube 13 by sliding fit. The inner tubes 14 are connected by a connecting rod 15. L-shaped plates 16 are symmetrically installed on the left and right side walls of the die-cutting machine body 1. An electric slider 17 is installed on the inner end of the L-shaped plate 16. The electric slider 17 is installed on the inner end of the L-shaped plate 16. A moving frame is installed on the inner end of the slider 17, and the other end of the moving frame is connected to the outer wall of the inner tube 14. When working, the electric slider 17 is a linear guide slider structure, and the motor drives the lead screw to rotate to control the linear movement of the device. The cardboard enters the die-cutting machine body 1 through the feed port 2, and the fixed fan 11 is started. The wind passes through the fixed cavity 12 and enters the outer tube 13, and then enters the inner tube 14. The electric slider 17 is started, driving the inner tube 14 to move forward, thereby blowing out the dust on the cardboard from the inside to the outside, effectively preventing the dust from falling into the die-cutting machine body 1, thereby damaging its internal structure, and facilitating the recovery and cleaning of the dust.

[0022] A bottom cavity 18 is installed at the bottom of the die-cutting machine body 1, and an adjusting cylinder 25 is installed at the bottom of the bottom cavity 18. A placement cavity 19 is installed at the output end of the adjusting cylinder 25. A long rod is arranged above the placement cavity 19, and a pressing plate 21 is installed on the upper end surface of the long rod. The pressing plate 21 is arranged in the feed port 2. When working, the adjusting cylinder 25 is started to drive the pressing plate 21 to move downward, thereby limiting and fixing the cardboard to avoid the cardboard from shifting during the hot stamping process, resulting in misalignment of the printed pattern.

[0023] An adjusting screw 22 is rotatably installed on the left end surface of the placement cavity 19 through a bearing. The adjusting screw 22 is symmetrical on the left and right and the threads are in opposite directions. The adjusting screw 22 is symmetrically screwed with an adjusting slider on the left and right. A long rod is installed on the upper end surface of the adjusting slider. Long holes are symmetrically opened on the bottom of the die-cutting machine body 1. The long rod is arranged in the long hole. When working, the adjusting screw 22 is rotated to drive the pressing plate 21 to move left and right, so that cardboards of different specifications can be limited and fixed, thereby improving the wide application of the device.

[0024] A control panel 23 is installed on the left end surface of the bottom cavity 18. The control panel 23 is electrically connected to the electric slider 17. When working, a PLC program is written in the control panel 23 to control the operation of each device.

[0025] The bottom of the bottom cavity 18 is symmetrically installed with telescopic rods 24, and the upper end surface of the telescopic rods 24 is installed with a placement cavity 19. When working, the telescopic rod 24 structure is adopted to ensure that the placement cavity 19 remains stable on the left and right to avoid the placement cavity 19 from tilting slightly, which causes one side of the pressure plate 21 to lose the limiting effect on the cardboard.

[0026] The placement cavity 19 is connected to the left and right side walls of the bottom cavity 18 by means of a sliding fit. During operation, the sliding fit is adopted to ensure the stability of the placement cavity 19 when it moves up and down.

[0027] During specific operation, the electric slider 17 is a linear guide slider structure. The motor drives the lead screw to rotate to control the linear movement of the device. The cardboard enters the die-cutting machine body 1 through the feed port 2, and the fixed fan 11 is started. The wind passes through the fixed cavity 12 and enters the outer tube 13, and then enters the inner tube 14. The electric slider 17 is started, driving the inner tube 14 to move forward, thereby blowing out the dust on the cardboard from the inside to the outside, effectively preventing the dust from falling into the die-cutting machine body 1 and damaging its internal structure, making it easy to recover and clean the dust.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
