Description

Technical Field

[0001] This utility model relates to the field of material cutting device technology, and in particular to a rapid cutting device for cosmetic packaging materials. Background Technology

[0002] A cosmetic packaging material slitting device is a piece of equipment used to cut large rolls of cosmetic packaging materials, such as plastic film, paper, and aluminum foil, into preset sizes and shapes. It is typically used in the packaging stage of a cosmetic production line and can process packaging materials into small pieces or specific shapes suitable for packaging various cosmetics (such as lipstick, foundation, and eyeshadow), thereby meeting the needs of subsequent packaging processes.

[0003] Traditional slitting devices typically have slitting blades that are only adjustable in height, resulting in inaccurate cutting positions and difficulty in meeting the high-precision dimensional requirements of cosmetic packaging. Furthermore, when faced with variations in the size, thickness, and cutting requirements of packaging materials for different brands and models of cosmetics, traditional devices often require manual adjustments, which is not only inefficient but also makes it difficult to ensure consistent cutting quality. Due to the inconvenience of adjustment and insufficient precision, the production efficiency of traditional devices is also relatively low, making it difficult to meet the needs of large-scale, rapid production.

[0004] Therefore, those skilled in the art have provided a rapid cutting device for cosmetic packaging materials to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a rapid cutting device for cosmetic packaging materials. A first servo motor drives a first threaded rod, causing a first sliding block to adjust the horizontal position of the mounting frame. A second servo motor drives a second threaded rod, causing a second sliding block to adjust the horizontal position of the cutting blade. An electric push rod controls the height of the cutting blade. This multi-directional adjustment mechanism allows the device to adapt to different cutting tasks and packaging material specifications, meeting the packaging needs of various cosmetics. An arc-shaped plate prevents direct contact between the blade and the conveyor belt, avoiding damage. A cutting groove guides the blade during cutting, improving accuracy and cut quality.

[0006] To achieve the above objectives, this utility model provides a rapid cutting device for cosmetic packaging materials, comprising two vertical plates, a top plate, and two fixed plates. A first mounting groove is formed in the middle of the lower surface of the top plate. A first servo motor is fixedly connected to the inner wall of the rear end of the first mounting groove. A first threaded rod is provided inside the first mounting groove. The output end of the first servo motor is fixedly connected to the middle of the rear end of the first threaded rod. A first sliding block is threadedly connected to the outer wall of the first threaded rod. A mounting frame is fixedly connected to the lower end of the first sliding block. A second mounting groove is formed in the middle of the lower surface of the mounting frame. A second threaded rod is provided inside the second mounting groove. A second servo motor is fixedly connected to the inner wall of one side of the second mounting groove. The output end of the second servo motor is fixedly connected to the middle of one side of the second threaded rod. A second sliding block is threadedly connected to the outer wall of the second threaded rod. An electric push rod is fixedly connected to the lower surface of the second sliding block. A fixed frame is fixedly connected to the output end of the electric push rod. A cutting tool is rotatably connected to the middle of the lower end of the fixed frame. An arc-shaped plate is provided at the lower end of the cutting tool. A cutting groove is formed in the middle of the upper surface of the arc-shaped plate.

[0007] Through the above technical solution, the first servo motor drives the first threaded rod, causing the first sliding block to adjust the position of the mounting frame in the horizontal front-back direction. The second servo motor drives the second threaded rod, causing the second sliding block to adjust the position of the lower cutting blade in the horizontal lateral direction. Furthermore, the electric push rod allows the cutting blade to be height-adjusted. This multi-directional adjustment enables the device to adapt to various cutting tasks and packaging material specifications, easily handling changes in the size, thickness, and cutting requirements of packaging materials for different brands and models of cosmetics. In addition, the arc plate prevents the cutting blade from directly contacting the conveyor belt, avoiding damage. The cutting groove guides the blade during cutting, improving cutting accuracy and cut quality.

[0008] Furthermore, protective shells are fixedly connected to the front and rear ends of one side of the lower surface of the top plate. A fourth servo motor is installed inside each of the protective shells. A third threaded rod is fixedly connected to the output end of each of the fourth servo motors. Guide rods are fixedly connected to the front and rear ends of the other side of the lower surface of the top plate. The inner wall of one side of the fixed plate is threadedly connected to the outer wall of the third threaded rod. The inner wall of the other side of the fixed plate is slidably fitted to the outer wall of the guide rod. A pressure plate is installed at the lower end of each fixed plate. Multiple telescopic rods are fixedly connected to the upper surface of each pressure plate. The telescopic ends of each telescopic rod are fixedly connected to the lower surface of the fixed plate. A return spring is sleeved on the outside of each telescopic rod. The upper and lower ends of each return spring are fixedly connected to the lower surface of the fixed plate and the upper surface of the pressure plate, respectively. A rubber pad is fixedly connected to the lower surface of the pressure plate.

[0009] Through the above technical solution, the fourth servo motor drives the third threaded rod to move the fixed plate, which can control the clamping force of the pressure plate on the material. By adjusting the rotation angle and speed of the fourth servo motor, different pressure requirements can be met, ensuring that the material remains stable during the cutting process. Through the cooperation of the telescopic rod and the return spring, the pressure plate can automatically return to its original position after clamping the material. When the pressure plate presses down, the telescopic rod retracts, and the pressure plate can automatically lift under the action of the return spring, avoiding the trouble of manual reset and improving work efficiency. In addition, the pressure plate can uniformly clamp the material, preventing the material from moving or deforming during the cutting process and protecting the surface quality of the material.

[0010] Furthermore, a mounting plate is fixedly connected to the lower outer wall of the rear end of one side of the vertical plate, and a third servo motor is fixedly connected to the upper surface of the mounting plate. The output end of the third servo motor on one side passes through the vertical plate to the other side of the vertical plate and is fixedly connected to a first rotating rod. Both sides of the outer wall of the first rotating rod are fixedly connected to a drive gear, and a second rotating rod is provided at the front end of the first rotating rod. Both sides of the outer wall of the second rotating rod are fixedly connected to a driven gear. A conveyor belt is provided in the middle of the adjacent two sides of the vertical plate.

A support plate is fixedly connected to the middle of the outer walls of the adjacent two sides of the vertical plate, and the upper surface of the support plate is tightly fitted to the inner top surface of the conveyor belt.

[0011] Through the above technical solution, the third servo motor drives the first rotating rod, which, in combination with the second rotating rod and the meshing transmission of the driving gear and the driven gear, stably transmits the power of the third servo motor to the conveyor belt, ensuring a smooth and slip-free conveying process and improving the reliability of the conveying. In addition, the support plate provides the main lower support for the conveyor belt, ensuring that the conveyor belt remains flat during operation and preventing excessive sagging or deformation, thus ensuring the stability of the conveying.

[0012] Furthermore, a support frame is fixed to the middle of the outer wall of the vertical plate on the side away from the center of the conveyor belt. The upper end of the support frame is fixedly connected to the middle of both sides of the outer wall of the top plate. A PLC control panel is fixedly connected to the outer wall of the front end of one side of the vertical plate.

[0013] The above technical solution uses a support frame to firmly connect the vertical plate and the top plate together, forming a stable frame structure. This structure can effectively resist the vibration and impact forces that may be generated during the operation of the equipment, improving the stability and rigidity of the overall structure. The operation of the device is controlled by a PLC control panel.

[0014] Furthermore, the front end of the first threaded rod is rotatably connected to the inner wall of the front end of the first mounting groove, and the outer wall of the first sliding block is slidably fitted to the inner wall of the first mounting groove.

[0015] The above technical solution and design make the movement of the first sliding block, the mounting frame and its lower structure, more stable.

[0016] Furthermore, the other side of the second threaded rod is rotatably connected to the inner wall of the other side of the second mounting groove, and the outer wall of the second sliding block is slidably fitted with the inner wall of the second mounting groove;

[0017] The above technical solution and design make the movement of the slitting tool driven by the second sliding block more stable.

[0018] Furthermore, connecting rods are fixedly connected to both sides of the upper surface of the arc-shaped plate, and the upper ends of the connecting rods are fixedly connected to the lower surface of the mounting frame. The arc-shaped plate is located at the upper end of the conveyor belt.

[0019] The above technical solution connects the arc-shaped plate to the mounting frame using a connecting rod.

[0020] Furthermore, T-shaped blocks are fixedly connected to both sides of the upper surface of the mounting bracket, and T-shaped grooves are opened on both sides of the lower surface of the top plate. The outer walls of the T-shaped blocks are slidably fitted with the inner walls of the T-shaped grooves.

[0021] The above technical solution, through the design of T-slots and T-blocks, ensures that the mounting frame remains horizontal when moving back and forth, avoiding any lateral offset or swaying. Furthermore, the large contact area of ​​the T-slots and T-blocks provides stable support, capable of bearing the weight of the mounting frame and the slitting tools and other components connected to it.

The second servo motor 6 drives the second threaded rod 601, which drives the second sliding block 602 and the cutting blade 605 to move in the horizontal lateral direction, accurately positioning the material. Then, the fourth servo motor 8 drives the third threaded rod 801, which pushes the fixed plate 803 and the pressure plate 804 downward. The telescopic rod 805 compresses the return spring 806, causing the rubber pad 807 on the pressure plate 804 to press the package... The packaging material is pressed between the conveyor belt 505 and the arc plate 7 to prevent it from moving or deforming during the cutting process. Finally, the electric push rod 603 controls the cutting blade 605 to move up and down in the height direction, pressing the blade down and guiding it through the cutting groove 701 on the arc plate 7 to cut the packaging material. The lower surface of the arc plate 7 is in close contact with the upper surface of the conveyor belt 505.
