Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of embossing and slitting of packaging bags, and specifically relates to an embossing and slitting assembly for packaging bags. Background Technique
[0002] The embossing and slitting assembly for packaging bags is usually used to manufacture packaging bags with specific textures and shapes to improve the appearance and functionality of products. The embossing technology is to print patterns or textures on packaging materials through heating and pressure to make them have a raised effect. It is often used to enhance the visual appeal of packaging bags, improve the brand image or the texture of products. The slitting technology is to use a die to cut packaging materials (such as paper, plastic film) into specific shapes and sizes. The shape of the packaging bag can be customized, such as rounded corners, special shapes, etc., to meet the packaging needs of different products. Using an automated embossing and slitting assembly can greatly improve production efficiency and reduce the cost and error of manual operation. Precise slitting and embossing can ensure the consistency of each packaging bag in terms of quality and appearance. Heating can make the packaging bag material soft and easy to process, so that the cutting tool can cut more precisely, ensuring that each packaging bag has a consistent shape and size. Heating can reduce the risk of tearing or damage to the packaging bag during the cutting process. This is because the heated material is softer, and the stress distribution during cutting is more uniform, making it less likely to cause damage to the edges or corners.

[0053] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.
[0054] As shown Figure 1 in FIG. Figure 1 , it is an embodiment of an embossing assembly for a packaging bag provided by the present utility model. In this embodiment, it includes a driving assembly 10, a heat-conducting assembly 20, and a cutting knife 30. The driving assembly 10 is arranged on the top of the heat-conducting assembly 20 and is used to drive the heat-conducting assembly 20 to move up and down. A cutting knife 30 is fixed to the bottom of the heat-conducting assembly 20, and the cutting knife 30 is used to emboss and cut the packaging bag. A heating assembly 40 is arranged between the heat-conducting assembly 20 and the driving assembly 10, and the heating assembly 40 is used to generate heat. The heat-conducting coefficient of the heat-conducting assembly 20 is greater than that of the cutting knife 30, so that the heat at the position where the bottom of the cutting knife 30 contacts the packaging bag is constant, making the embossed and cut patterns on the packaging bag uniform.
[0055] The driving assembly 10 is a driving cylinder.
[0056] Among them, in the above technical solution, there are two heat-conducting assemblies 20, which are respectively fixedly connected to the output end of the driving assembly 10 and the top of the cutting knife 30.
[0057] Further, in the above technical solution, the top area of the cutting knife 30 is larger than the bottom area of the heat-conducting assembly 20.
[0058] Further, in the above technical solution, the shape of the cutting knife 30 is set according to the structure of the embossing and cutting of the packaging bag.
[0059] Further, in the above technical solution, an insulating and heat-insulating layer is arranged at the contact position between the driving assembly 10 and the heating assembly 40.
[0060] Further, in the above technical solution, the heating assembly 40 is a heating wire, and its area is the same as the top area of the heat-conducting assembly 20.
[0061] Further, in the above technical solution, the thickness of the cutting knife 30 is less than the height of the heat-conducting assembly 20.

[0064] Further, in the above technical solution, the cutting knife 30 is made of one of carbon steel and iron.
[0065] Heating system: The heating system consists of heating wires, which are placed in the heat-conducting component. The function of the heating wires is to generate heat, and the heat is transferred to the bottom of the cutting knife through the heat-conducting component. The purpose of this is to ensure that when the cutting knife touches the surface of the packaging bag, it can be quickly heated, so as to form the expected pattern or design on the packaging bag, and provide the necessary heat during slitting to ensure clear and smooth cutting.
[0066] Driving system: The driving system usually adopts a cylinder drive, and the movement of the driving cylinder is controlled by air pressure. This design enables the cutting knife to perform embossing and slitting operations on the packaging bag under a certain pressure and speed in a heated state. The key to the driving system is to ensure the stability of the cutting pressure and speed to ensure the consistency and quality of the processing effect of each packaging bag.
[0067] Cutting knife and heat-conducting component: The cutting knife is usually made of materials with high hardness and strong wear resistance, such as carbon steel. Their design and shape depend on the required embossing and slitting effects. The bottom of the cutting knife directly contacts the heat-conducting component, and the heat-conducting component is usually made of metal materials with good heat conductivity (such as copper or aluminum) to quickly and evenly transfer the heat generated by the heating wires to the working surface of the cutting knife.
[0068] During the operation, first heat the bottom of the cutting knife to the set temperature through the heating system, and then control the movement of the cutting knife through the driving system to perform embossing and slitting operations on the surface of the packaging bag. The heating design can ensure that during the cutting process, the cut is neat and material tearing or other damages are avoided.
[0069] Specifically, the principle of the present utility model is as follows: When in use, ensure that the driving component, heat-conducting component, cutting knife, heating component and insulation and heat insulation layer are installed correctly and connected to the control system. Check the working status and parameter settings of the heating wires and driving cylinders to ensure that the system is ready. According to the specific packaging bag material and thickness, set the temperature control of the heating component to ensure that the cutting area reaches an appropriate temperature. Adjust the pressure and moving speed of the driving cylinder to meet different embossing and slitting requirements. Start the heating component to evenly heat the heat-conducting component and the bottom of the cutting knife to the set temperature. Place the packaging bag to be embossed and slit in the working area to ensure accurate positioning. Start the driving cylinder through the control system to make the cutting knife contact the surface of the packaging bag with an appropriate pressure and speed. When the bottom of the cutting knife touches the packaging bag, due to the effect of the heat-conducting component, the temperature at the bottom of the cutting knife will be quickly conducted to the surface of the packaging bag. This can form a predetermined pattern or design on the packaging bag. As needed, the cutting knife will cut the packaging bag along the designed slitting line in a heated state to ensure that the cut is neat and accurate. During the initial operation, monitor the cutting effect and embossing quality. Adjust the heating temperature, cutting pressure or cutting speed as needed to optimize the product quality and production efficiency.
