Description

Technical Field

[0001] This utility model relates to the field of die-cutting machines, and in particular to an automatic alignment and feeding device for a sheet 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 various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. When die-cutting sheet materials, a feeding mechanism is set up to feed the die-cutting material in order to ensure production continuity and improve production efficiency.

[0003] In current technology, when die-cutting sheet materials, a conveyor belt is usually used to feed the die-cutting material. At the same time, a fixing plate is used to fix one part of the sheet material and transport it with the conveyor belt. During the transportation process, the edge of the sheet material is prone to tilting, which will affect the cutting accuracy of the sheet material. Utility Model Content

[0004] Therefore, it is necessary to provide an automatic alignment and feeding device for a sheet die-cutting machine to address the problem that the edges of sheet materials are prone to tilting during the conveying process, which affects the cutting accuracy of the sheet materials.

[0005] Includes: a die-cutting machine body, wherein an electric conveyor belt is installed on the inner side of the die-cutting machine body frame; The fixing mechanism includes a fixing component disposed on the inner side of the die-cutting machine body frame. Fixing rods are fixedly connected to both sides of the die-cutting machine body frame. A second electric push rod is fixedly connected to the inner wall of each fixing rod. A moving block is fixedly connected to the telescopic end of the second electric push rod. A bolt is threadedly connected to the inner wall of the moving block. A mounting rod is rotatably connected to the bottom end of the bolt. Multiple moving rods are slidably connected to the bottom end of the mounting rod. A circular roller is rotatably connected to the lower inner wall of each moving rod. A connecting rod is rotatably connected to the top end of each moving rod. The opposite ends of two adjacent connecting rods are hinged.

[0006] In one embodiment, the fixing mechanism further includes two movable plates mounted to the fixing assembly. A crossbar is slidably connected to one side of each movable plate, and the inner wall of the crossbar is fixedly connected to the surface of one of the movable rods. Pull rods are fixedly connected to opposite sides of the two mounting rods, and the ends of the two pull rods away from the mounting rods are rotatably connected to the ends of two connecting rods, respectively. The pull rods help ensure stability when the crossbar pulls the multiple movable rods to unfold, thereby ensuring the effectiveness of the device.

[0007] In one embodiment, the fixing component includes an electric slider slidably connected to the inner side of the die-cutting machine frame. A support plate is fixedly connected to one side of the electric slider, and a first electric push rod is embedded in the inner wall of the support plate. A fixing plate is fixedly connected to the telescopic end of the first electric push rod. This design allows the electric conveyor belt to transport materials larger than the sliced ​​material while the support plate and fixing plate clamp and transport the sliced ​​material synchronously, ensuring the stability of the movement of the sliced ​​material during transport.

[0008] In one embodiment, two sliders are slidably connected to one side of the fixed plate, and one side of each slider is fixedly connected to the side of the two movable plates away from the crossbar. This facilitates the synchronous movement of the movable plates while the fixed plate moves in the fixing assembly, and also facilitates the synchronous operation of multiple rollers with the fixed plate.

[0009] In one embodiment, a round rod is slidably connected to the top end of the mounting rod, and the top end of the round rod extends through the moving block. This facilitates limiting the vertical movement path of the mounting rod.

[0010] In one embodiment, a plurality of the circular rollers are arranged longitudinally on the same axis and are flush. This ensures that the multiple rollers effectively limit the movement of the sliced ​​material at the edge.

[0011] In one embodiment, the bottom end of the mounting rod is provided with a sliding groove, and the upper surface of the movable rod is slidably connected to the inner wall of the sliding groove, which helps to limit the movement path of the movable rod.

[0012] In one embodiment, a corrugated cover is fixedly connected between the top end of the mounting rod and the bottom end of the movable block, and the bolt is located inside the corrugated cover. This facilitates the protection of the bolt.

[0013] Beneficial effects 1. The fixing mechanism described above, through the fixing component, facilitates the simultaneous conveying and clamping of the sliced ​​material by the electric conveyor belt, ensuring stability during the feeding process. Furthermore, multiple rollers limit the edges of the sliced ​​material during feeding, preventing tilting. The rollers operate synchronously with the fixing component, improving the consistency of the device's operation. The constant edge-limiting by the rollers during feeding ensures slicing accuracy and improves the cutting quality of the sliced ​​material. 2. In this solution, the horizontal position of multiple moving rods is adjusted by the second electric push rod, and the vertical height of multiple moving rods is adjusted by bolts. This is beneficial for limiting the edge of sliced ​​materials of different heights and thicknesses, and improves the practicality of the device. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figure 1 - Figure 6 This invention describes the automatic alignment and feeding device for a sheet die-cutting machine.

[0019] In one embodiment, an automatic alignment and feeding device for a sheet die-cutting machine includes: a die-cutting machine body 100, and an electric conveyor belt 200 installed on the inner side of the frame of the die-cutting machine body 100. The fixing mechanism 300 includes a fixing component 310 disposed inside the frame of the die-cutting machine body 100. Fixing rods 320 are fixedly connected to both sides of the die-cutting machine body 100 frame. A second electric push rod 321 is fixedly connected to the inner wall of the fixing rod 320. A moving block 322 is fixedly connected to the telescopic end of the second electric push rod 321. A bolt 323 is threadedly connected to the inner wall of the moving block 322. An installation rod 330 is rotatably connected to the bottom end of the bolt 323. Multiple moving rods 340 are slidably connected to the bottom end of the installation rod 330. A roller 350 is rotatably connected to the lower end of the inner wall of the moving rod 340. A connecting rod 351 is rotatably connected to the top end of the moving rod 340. The opposite ends of two adjacent connecting rods 351 are hinged.

[0020] It should be noted that: The die-cutting machine body 100 includes: The frame is the main support structure of the die-cutting machine. It is usually made of high-strength steel by welding or casting. It provides a stable mounting base for other components, ensures the rigidity and stability of the die-cutting machine during operation, and reduces vibration and deformation. Transmission components: Motor: This is the power source for the die-cutting machine, usually a servo motor or a stepper motor; Reducer: This connects the motor and the drive shaft, used to reduce the motor speed and increase torque to meet the working requirements of the die-cutting machine; Die-cutting components: The die-cutting blade is one of the core components of the die-cutting machine. It is designed and manufactured according to the shape and size of the product being processed. The die-cutting blade usually consists of a die, a bottom die, and a die-cutting pad. Die-cutting blade holder: Used to install and fix the die-cutting blade and drive the blade to move up and down to achieve die-cutting of the sheet material. Pressure adjustment device: Used to adjust the pressure of the die-cutting blade on the sheet material to adapt to the die-cutting requirements of different materials. The electric conveyor belt 200 includes two rotating rollers rotatably connected to the inside of the die-cutting machine body 100. A conveyor belt is connected between the two rotating rollers. A motor is fixedly connected to one side of the die-cutting machine body 100. The output shaft of the motor is fixedly connected to one end of one of the rotating rollers. The die-cutting pad in the die-cutting die is set inside the conveyor belt, and the top of the die-cutting pad is in contact with the surface of the conveyor belt.

[0021] In this embodiment, the overall shape of the movable block 322 is U-shaped, and the inner wall of the movable block 322 is slidably connected to the surface of the fixed rod 320, thereby limiting the movement of the movable block 322.

[0022] like Figure 3 , Figure 4 and Figure 5As shown, the fixing mechanism 300 also includes two movable plates 370 mounted on the fixing assembly 310. A crossbar 371 is slidably connected to one side of the movable plate 370. The inner wall of the crossbar 371 is fixedly connected to the surface of one of the movable rods 340. Pull rods 360 are fixedly connected to the opposite sides of the two mounting rods 330. The ends of the two pull rods 360 away from the mounting rods 330 are rotatably connected to the ends of the two connecting rods 351 respectively.

[0023] In this embodiment, the surface of the moving rod 340 near the crossbar 371 is installed on the inner wall of the crossbar 371, and the end of the connecting rod 351 at the farthest distance from the crossbar 371 is rotatably connected to the end of the pull rod 360. A sliding groove is provided on one side of the moving plate 370, and the crossbar 371 can move up and down along the sliding groove.

[0024] like Figure 2 and Figure 3 As shown, the fixing component 310 includes an electric slider 311 that is slidably connected to the inner side of the frame of the die-cutting machine body 100. A support plate 312 is fixedly connected to one side of the electric slider 311. A first electric push rod 313 is embedded in the inner wall of the support plate 312. A fixing plate 314 is fixedly connected to the telescopic end of the first electric push rod 313.

[0025] In this embodiment, when the support plate 312 and the fixing plate 314 move to the closest distance in the direction of the die-cutting blade, the distance between the support plate 312 and the fixing plate 314 and the die-cutting blade can ensure that the multiple rollers 350 approach to the closest distance.

[0026] When the two adjacent rollers 350 in the longitudinal direction move away from each other to the farthest distance, the fixed plate 314 moves away from the die-cutting blade to the farthest distance. At this time, the angle between the two adjacent connecting rods 351 is the largest. The support plate 312 is set on the inner side of the conveyor belt, and the top of the support plate 312 is in contact with the surface of the conveyor belt. The top of the support plate 312 is flush with the top of the die-cutting pad.

[0027] It should be noted that an electric slide rail is installed on one side of the inner wall of the die-cutting machine body 100 frame. The operation of the electric slide rail and the electric conveyor belt 200 do not affect each other. The electric slide rail includes a servo motor, a lead screw, and a limit block. One end of the lead screw is fixedly connected to the output shaft of the motor. The inner wall of the limit block is threadedly connected to the surface of the lead screw. The electric slider 311 is fixedly connected to the opposite side of the limit block. The servo motor is started by the controller, causing the output shaft of the servo motor to rotate clockwise, thereby driving the lead screw to rotate synchronously. The limit block drives the electric slider 311 to move away from the die-cutting blade. The servo motor is started by the controller, causing the output shaft of the servo motor to rotate counterclockwise. At this time, the lead screw rotates counterclockwise, and the limit block drives the electric slider 311 to move closer to the die-cutting blade.

[0028] like Figure 4 As shown, two sliders are slidably connected to one side of the fixed plate 314, and one side of each slider is fixedly connected to the side of the two movable plates 370 away from the crossbar 371.

[0029] In this embodiment, a groove matching the slider is provided on one side of the fixed plate 314, and the slider can move horizontally in the groove. Under the action of the slider, when the fixed plate 314 moves horizontally, it will drive the moving plate 370 and the crossbar 371 to move synchronously.

[0030] like Figure 6 As shown, a round rod 331 is slidably connected to the top of the mounting rod 330, and the top of the round rod 331 extends through the moving block 322.

[0031] In this embodiment, the surface of the round rod 331 is slidably connected to the inner wall of the moving block 322, and the round rod 331 limits the up and down movement of the mounting rod 330.

[0032] like Figure 5 As shown, multiple longitudinal rollers 350 are arranged on the same axis, and the multiple rollers 350 are flush.

[0033] In this embodiment, when the drive roller 350 moves downward to limit the edge of the slice material, the lower ends of the surfaces of multiple rollers 350 will simultaneously contact the slice material.

[0034] like Figure 5 As shown, a groove is provided at the bottom end of the mounting rod 330, and the upper surface of the movable rod 340 is slidably connected to the inner wall of the groove. The groove limits the movement path of the movable rod 340.

[0035] like Figure 3 As shown, a corrugated cover is fixedly connected between the top end of the mounting rod 330 and the bottom end of the moving block 322, and bolts 323 are located on the inner side of the corrugated cover. The corrugated cover is a rubber frame, and when the roller 350 limits the cutting material, the corrugated cover protects the bolts 323.

[0036] Working principle: The material to be sliced ​​is placed at the top of the electric conveyor belt 200. At this time, the controller activates two second electric push rods 321 to push the corresponding moving blocks 322, which in turn move the mounting rod 330 closer to the edge of the slicing material. When the mounting rod 330 moves multiple rollers 350 above the edge of the slicing material, two bolts 323 are rotated in sequence to push the mounting rod 330 downward. This causes the mounting rod 330 to move multiple rollers 350 downward through multiple moving rods 340, so that the surfaces of the multiple rollers 350 contact and adhere to the edge of the slicing material, thereby limiting the edge of the slicing material. The electric slider 311 drives the support plate 312 and the fixed plate 314 to move away from the die-cutting plate. At this time, the multiple rollers 350 will move and rotate in contact with the surface of the slicing material. When the support plate 312 and the fixed plate 314 move to their furthest distance away from the die-cutting blade, the controller activates the first electric push rod 313 to move the fixed plate 314 downwards to press against the top of the material being sliced. At this point, the material being sliced ​​is fixed and limited. Then, the electric slider 311 is driven to move the support plate 312 and the fixed plate 314 closer to the die-cutting blade. Simultaneously, the controller activates the electric conveyor belt 200. Under the action of the electric conveyor belt 200 and the support plate 312 and the fixed plate 314, the material being sliced ​​is conveyed towards the die-cutting blade. During the process of conveying the material, multiple longitudinal rollers 350 move closer to each other and always limit the edge of the material being sliced. Once the material is in place, it can be sliced.

[0037] It should be noted that the motors, controllers, and sensors mentioned above are all devices with relatively mature existing technologies. Specific models can be selected according to actual needs. At the same time, the motors, controllers, and sensors can be powered by built-in power supplies or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
