Abstract

This utility model discloses a die-cutting pressure adjustment mechanism for a die-cutting machine, including a feeding device. A U-shaped frame is fixedly installed on the upper surface of the feeding device. Two hydraulic cylinders are installed on the top of the U-shaped frame, and a movable plate is fixedly installed on the bottom of the two hydraulic cylinders. The outer surfaces of both ends of the movable plate are slidably installed with the inner walls on both sides of the U-shaped frame. A pressure adjustment component and an adjustable die assembly are sequentially arranged on the outside of the movable plate. The operator can use the pressure adjustment component and the adjustable die assembly to make the threaded rod sleeved in the middle of the three transmission wheels rotate synchronously. The sleeve moves up or down along the outer surface of the threaded rod to adjust the height of the adjustable die assembly. Thus, when the hydraulic cylinder pushes the movable plate and the pressure adjustment component and the adjustable die assembly on it to perform the same lifting operation, different pressure effects are presented due to the change in the height of the adjustable die assembly adjusted by the pressure adjustment component, thereby achieving the effect of adjusting the die-cutting pressure of the die-cutting machine.

Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and more specifically, to a die-cutting pressure adjustment mechanism for a die-cutting machine. Background Technology

[0002] Die-cutting machines are devices used for precise cutting, creasing, and punching of materials such as paper, cardboard, plastic, leather, and fabric. They are widely used in bookbinding, packaging box making, and label production. However, some problems still exist in actual use. For example, the die-cutting pressure adjustment mechanism is a key component to ensure processing quality and efficiency. Operators adjust the relative height difference between the die and the material, allowing the die to adapt to the characteristics and processing requirements of different materials under the control of the reciprocating lifting mechanism, thus completing cutting, creasing, and punching. However, adjusting the die usually requires manual rotation of the height control screw, which is not only time-consuming but also reduces the convenience of adjustment, thereby affecting the practicality and efficiency of the die-cutting machine. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a die-cutting pressure adjustment mechanism for a die-cutting machine, so as to solve the problem that in the prior art, manually rotating the screw that controls the height when adjusting the die-cutting mold is time-consuming and inconvenient, which affects the practicality and working efficiency of the die-cutting machine.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a die-cutting pressure adjustment mechanism for a die-cutting machine, including...

[0005] A feeding device is provided, wherein a U-shaped frame is fixedly installed on the upper surface of the feeding device, two hydraulic cylinders are provided on the top of the U-shaped frame, and a movable plate is fixedly installed on the bottom end of the two hydraulic cylinders. The outer surfaces of both ends of the movable plate are slidably installed with the inner walls of both sides of the U-shaped frame. A pressure regulating component and an adjustable pressure mold component are sequentially provided on the outside of the movable plate.

[0006] The pressure regulating assembly includes a transmission wheel, a threaded rod, a limiting sleeve, and a motor. Three transmission wheels are arranged on the top of the movable plate, and the outer surfaces of the three transmission wheels are provided with transmission tracks. The transmission wheels mesh with the transmission tracks. The middle part of the transmission wheel is fixedly sleeved with the top end of the threaded rod. The outer surface of the bottom end of the threaded rod is threadedly connected to a sleeve. The bottom of the sleeve is fixedly installed on the upper surface of the adjustable pressure mold assembly. Two limiting sleeves are provided, and the outer surfaces of the two limiting sleeves are fixedly sleeved with the inner wall of the movable plate. The bottom ends are fixedly installed on the upper surface of the adjustable pressure mold assembly. The output end of the motor is fixedly sleeved with the middle part of one of the transmission wheels.

[0007] It also includes a sorting component, which is disposed at the end of the feeding device.

[0008] The adjustable pressure mold assembly includes a horizontal plate and a second motor. The upper surface of the horizontal plate is fixedly installed to the bottom of the sleeve and the bottom end of the limiting sleeve, respectively. Two vertical plates are fixedly installed on the lower surfaces of both ends of the horizontal plate. A rotating roller is rotatably installed in the middle of the two vertical plates. The second motor is located on the side of one of the vertical plates, and the output end of the second motor is fixedly sleeved with the middle of the rotating roller. Multiple pressure mold components are fixedly installed around the outer surface of the rotating roller.

[0009] The sorting assembly includes a material support platform, a third motor, a worm gear, a worm wheel, a double-acting screw, connecting blocks, and push plates. The surface of the material support platform is fixedly installed on the side of the feeding device. The third motor is fixedly installed on the lower surface of the middle part of the material support platform. The output end of the third motor is fixedly sleeved with a worm gear. The two ends of the double-acting screw are rotatably sleeved with the inner walls of the bottom sides of the material support platform. The middle part of the double-acting screw is fixedly sleeved with a worm wheel, and the outer surfaces of both ends are threaded with connecting blocks. The worm wheel meshes with the worm gear. The outer surfaces of the tops of the two connecting blocks are slidably installed with the inner walls of the top of the material support platform, and push plates are fixedly installed at the tops. The two push plates are symmetrically arranged, and their bottoms are slidably installed with the upper surface of the material support platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In the above scheme, by setting up a pressure regulating component and an adjustable die assembly, when the die-cutting pressure of the die-cutting machine needs to be adjusted, the operator can control the motor to start, and the transmission wheel connected to its output end will start to rotate. Through the meshing transmission track, the other two transmission wheels will also rotate synchronously. The threaded rod sleeved in the middle of the three transmission wheels will rotate synchronously, causing the sleeve connected to its external thread to move up or down along the outer surface of the threaded rod, thereby adjusting the height of the adjustable die assembly at the bottom. At the same time, the movable slide rod in the sleeved limiting sleeve slides along the inside of the fixed sleeve, limiting the movement of the adjustable die assembly. Thus, when the hydraulic cylinder pushes the movable plate and the pressure regulating component and adjustable die assembly on it to perform the same lifting operation, different pressure effects will be presented due to the change in the height of the adjustable die assembly adjusted by the pressure regulating component, thereby achieving the effect of adjusting the die-cutting pressure of the die-cutting machine.

[0012] In the above solution, by setting up a sorting component, during the process of stacking paper raw materials on the top of the material support platform, the operator can control the motor to start three times, causing the worm gear sleeved at the output end to rotate, driving the meshing worm wheel to rotate, so that the two ends of the bidirectional lead screw rotate along the inner wall of the bottom of the material support platform. The two connecting blocks with external threads drive the push plates installed at the top to slide along the surface of the bidirectional lead screw and the surface of the material support platform respectively, so that the two symmetrical push plates move closer to each other. The relative position of the push plates is adjusted according to the actual paper specifications stacked, thereby centering and positioning the paper raw materials to improve the accuracy of subsequent processing.

[0022] The pressure regulating assembly 5 includes a transmission wheel 50, a threaded rod 51, a limiting sleeve 53, and a motor 55.

The bottom of the sleeve 52 is fixedly installed on the upper surface of the adjustable pressure mold assembly 6. Two limiting sleeves 53 are provided, and the outer surfaces of the two limiting sleeves 53 are fixedly sleeved with the inner wall of the movable plate 4. The bottom ends are fixedly installed on the upper surface of the adjustable pressure mold assembly 6. The output end of the motor 55 is fixedly sleeved with the middle part of one of the transmission wheels 50.

[0023] It also includes a sorting component 7, which is disposed at the end of the feeding device 1.

[0024] The adjustable pressure mold assembly 6 includes a horizontal plate 60 and a second motor 62. The upper surface of the horizontal plate 60 is fixedly installed with the bottom of the sleeve 52 and the bottom end of the limiting sleeve 53, respectively. Two vertical plates 61 are fixedly installed on the lower surfaces of both ends of the horizontal plate 60. A rotating roller 63 is rotatably installed in the middle of the two vertical plates 61. The second motor 62 is set on the side of one of the vertical plates 61, and the output end of the second motor 62 is fixedly sleeved with the middle of the rotating roller 63. Multiple pressure mold parts 64 are fixedly installed around the outer surface of the rotating roller 63.

[0025] By setting the adjustable pressure mold assembly 6, during the die-cutting process, the operator can control the motor 2 62 to start, and the rotating roller 63 connected to the output end of the motor 2 62 will rotate. The multiple pressure mold parts 64 of different specifications arranged around it will also rotate. Thus, the operator can adjust the bottom of the rotation of the appropriate pressure mold part 64 according to the actual required indentation effect, thereby improving the practicality of the device and the actual work efficiency.

[0026] The sorting component 7 includes a material support platform 70, a motor 71, a worm gear 72, a worm wheel 73, a double-acting screw 74, a connecting block 75, and a push plate 76.

The motor 71 is fixedly installed on the lower surface of the middle part of the material support platform 70. The output end of the motor 71 is fixedly sleeved with the worm gear 72. The two ends of the double-acting screw 74 are rotatably sleeved with the inner walls of the bottom sides of the material support platform 70. The middle part of the double-acting screw 74 is fixedly sleeved with the worm wheel 73, and the outer surfaces of both ends are threaded with connecting blocks 75.

The two connecting blocks 75 connected by the external threads drive the push plates 76 installed at the top to slide along the surface of the bidirectional lead screw 74 and the surface of the material support table 70 respectively, so that the two symmetrical push plates 76 move closer to each other. The relative position of the push plates 76 is adjusted according to the actual paper specifications stacked, thereby centering and positioning the paper raw materials to improve the accuracy of subsequent processing.

[0028] The working process of this utility model is as follows:

[0029] When the die-cutting pressure of the die-cutting machine needs to be adjusted, the operator can start the motor 55, and the transmission wheel 50 connected to its output end will start to rotate. Through the meshing transmission track 54, the other two transmission wheels 50 will also rotate synchronously. The threaded rod 51 sleeved in the middle of the three transmission wheels 50 will rotate synchronously, causing the sleeve 52 with its external thread connection to move up or down along the outer surface of the threaded rod 51, thereby adjusting the height of the adjustable die assembly 6 at the bottom. At the same time, the movable slide rod in the sleeved limiting sleeve 53 slides along the inside of the fixed sleeve, limiting the movement of the adjustable die assembly 6. Thus, when the hydraulic cylinder 3 pushes the movable plate 4 and the pressure adjustment component 5 and the adjustable die assembly 6 on it to perform the same lifting operation, different pressure effects will be presented due to the change in the height of the adjustable die assembly 6 adjusted by the pressure adjustment component 5, thereby achieving the effect of adjusting the die-cutting pressure of the die-cutting machine.
