A connecting part 43 is fixedly connected to the middle third fixing part 42, and a heated cutting blade 44 is fixedly connected to the lower end of the connecting part 43. Due to the precise cooperation between the fixed rods, fixing parts, connecting parts, and cutting blade, the entire cutter structure can maintain high stability. The equidistant arrangement of the fixing parts ensures the consistency of the position of each cutting blade during operation, thereby improving the cutting accuracy, especially in situations requiring high-precision cutting. By adjusting the connecting part, the height and angle of the cutting blade can be adjusted according to the thickness and hardness of different materials. This flexibility allows the adjusting cutter to adapt to the cutting needs of different types and specifications of packaging bags, films, or other materials, increasing the applicability of the equipment. The third fixing part 42 is fixedly connected to the housing 1. The fixed rods 41 are located on both sides of the pressure cover 3, and the heated cutting blade 44 is located below the pressure cover 3. The third fixing part 42 is a movable locking accessory used for adjusting the distance of the heated cutting blade 44.

[0020] Working Principle: Plastic packaging bags or films are fed into the equipment's feeding support rod 5 via a conveying system. The feeding support rod 5 is located on both sides of the upper end of the housing 1, serving to support and guide the material, ensuring that the material enters the cutting area smoothly and correctly. During this process, the material is positioned by gravity or other conveying methods, ready for cutting. The device's pressing mechanism 2 is driven by a telescopic cylinder 21, controlling the up-and-down movement of the pressure cap 3. The upper end of the telescopic cylinder 21 is fixedly connected to a first fixing member 22, and both ends are equipped with guide rods 23 to ensure the linear movement of the cylinder. Under the drive of the cylinder, the pressure cap 3 is precisely pressed down, pressing down on the material to be cut, ensuring that the material does not move during the cutting process. The pressure of the pressure cap 3 on the material can be adjusted as needed, and the pressure is precisely applied by the cylinder control. The core cutting part of this device is the adjusting blade 4, which includes two... The fixed rod 41 has multiple third fixing parts 42 arranged at equal intervals on it. Each third fixing part 42 is fixedly connected to a connector 43, and the lower end of the connector 43 is fixedly connected to a heated cutting blade 44. When the pressing mechanism presses down the cover 3, the adjusting blade 4 will automatically enter the cutting position as the pressure increases and begin to cut the material. The heated cutting blade 44 can easily cut plastic materials by heating and prevent burrs or tears from forming on the cutting edge, ensuring a neat and smooth cut. The height, angle and cutting depth of the cutting blade can be finely adjusted by adjusting the connector 43. The connector 43 can adjust the distance of the cutting blade 44 according to the thickness and hardness of different materials to ensure that packaging bags of different types and thicknesses can be accurately cut. The third fixing part 42 is a movable lock accessory, which makes the distance adjustment of the blade more flexible and convenient, and can be quickly adjusted as needed.
