Description

Technical Field

[0001] This utility model relates to the field of packaging film processing technology, and in particular to a cutting mechanism with adjustment function for packaging film processing. Background Technology

[0002] Packaging film, as an important component of the modern packaging industry, is widely used in many fields such as food, medicine, daily chemicals, and electronics. With the continuous growth of market demand and the increasing requirements of consumers for product packaging, the packaging film processing industry has experienced rapid development. Packaging film must not only possess good protective properties, such as moisture resistance, oxidation resistance, and UV protection, but also meet various requirements such as aesthetics, easy tearing, and environmental friendliness. In the production process of packaging film, cutting is a crucial step, and its accuracy and efficiency directly affect the quality and production cost of the packaging film. Accurate positioning during the cutting process is key to ensuring cutting precision. However, traditional cutting mechanisms are inconvenient for adjusting the width of the packaging film to be cut. They typically rely on manual visual inspection or simple rulers to position the width of the packaging film to be cut. This method has low accuracy, is easily affected by human factors, and is not convenient for limiting the cutting of packaging films of different thicknesses or for adjusting the tension of the packaging film during cutting. This can lead to slack or excessive tension, causing shaking, offset, and deformation, reducing the accuracy and stability of the cutting. Therefore, we propose a cutting mechanism with an adjustable function for packaging film processing to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a cutting mechanism with an adjustable function for packaging film processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cutting mechanism with adjustable function for packaging film processing includes: a first fixed plate and a second fixed plate. Guide rollers are rotatably mounted inside the first and second fixed plates. A tensioning assembly and two sets of limiting assemblies are disposed inside the first and second fixed plates. Each limiting assembly includes a bidirectional lead screw rotatably mounted inside the first fixed plate. Two sets of threaded plates are threadedly connected to the outer side of the bidirectional lead screw. Limiting rollers are rotatably mounted on one side of each of the two sets of plates. A fixing frame is disposed between the first and second fixed plates. A cutting assembly is disposed inside the fixing frame. The cutting assembly includes a gear and two sets of racks. Both sets of racks mesh with the gear. Connecting blocks are fixedly mounted at the bottom of each set of racks. Electric telescopic rods are fixedly mounted at the bottom of each set of connecting blocks. Cutting blades are fixedly mounted at the output ends of each set of electric telescopic rods. A winding roller is disposed on one side of the fixing frame.

[0006] Preferably, the tensioning assembly includes: a threaded rod, which is rotatably mounted inside a fixed plate, and a threaded block is threadedly connected to the outer side of the threaded rod, with a tensioning roller rotatably mounted on one side of the threaded block.

[0007] Preferably, a scale is provided on both sides of the fixing frame, a guide rod is slidably installed inside the two sets of racks, the two sets of guide rods are fixedly installed inside the fixing frame, a short plate is fixedly installed on both sides of the two sets of connecting blocks, the four sets of short plates are slidably installed inside the two sides of the fixing frame, and a pointer is fixedly installed on the top of the four sets of short plates. The two sets of pointers on the same side are respectively located at the bottom of the corresponding scale.

[0008] Preferably, the gear is rotatably mounted on the top inner wall of the fixed frame, a second motor is fixedly mounted on the top of the fixed frame, the output shaft of the second motor is fixedly connected to the gear, a base plate is fixedly mounted on the bottom of the first fixed plate and the second fixed plate, two sets of brackets are fixedly mounted on the top of the base plate, the take-up roller is rotatably mounted inside the two sets of brackets, a first motor is fixedly mounted on one side of the front bracket, and the output shaft of the first motor is fixedly connected to the take-up roller.

[0009] Preferably, a motor three and two sets of motor four are fixedly installed inside the fixing plate one, and the output shafts of the motor three and the two sets of motor four are respectively fixedly connected to the corresponding threaded rod and the bidirectional lead screw.

[0010] Preferably, a sliding rod and two sets of limiting rods are fixedly installed inside the second fixed plate. A slider is slidably installed on the outside of the sliding rod. One side of the slider is rotatably connected to the tension roller. Two sets of sliding plates are slidably installed on the outside of each of the two sets of limiting rods.

[0011] In this utility model, a cutting mechanism with adjustable function for processing packaging film is provided, which includes a fixed frame, a cutting component, a scale, and a second motor. By driving the second motor, the gear rotates, causing the gear to drive two sets of racks to move in opposite directions. This causes the two sets of connecting blocks to drive the short plates on both sides and the pointer to move in opposite directions. By observing the pointer and the scale, the width of the packaging film to be cut can be adjusted. Through the cooperation of the scale and the pointer, the operator can intuitively determine the width of the packaging film to be cut, which can ensure that the size of each cut is very accurate and avoid the size deviation caused by manual measurement error or insufficient equipment precision, thereby improving the cutting accuracy of the packaging film.

[0012] In this invention, a cutting mechanism with adjustable function for packaging film processing is provided. It includes a tensioning component and a limiting component. A third motor rotates, causing a threaded rod to rotate, which in turn causes a threaded block to move a tensioning roller on one side up and down, facilitating adjustment of the packaging film tension. Two fourth motors drive corresponding bidirectional lead screws, causing two threaded plates on the same side to move corresponding limiting rollers relative to each other. This allows adjustment of the distance between the two limiting rollers according to the thickness of the packaging film, thus facilitating the adjustment of the packaging film tension. Appropriate tension ensures the packaging film remains stable during transport, preventing slackness or excessive tightness that could cause shaking, shifting, or deformation. This meets the processing needs of packaging films of different materials, improving the equipment's versatility. It also facilitates the limiting and transporting of the packaging film, enabling precise cutting of packaging films of different thicknesses and ensuring the film travels steadily along a predetermined path without shifting or skewing, thereby guaranteeing the accuracy and stability of the cutting.

[0021] In this embodiment, the tensioning assembly 7 includes: a threaded rod 702, which is rotatably installed inside the fixed plate 1. A threaded block 703 is threadedly connected to the outer side of the threaded rod 702. A tensioning roller 704 is rotatably installed on one side of the threaded block 703 to facilitate the rotation of the threaded rod 702 and to facilitate the adjustment of the tension of the packaging film. A scale 5 is provided on both sides of the fixed frame 4. Guide rods 908 are slidably installed inside the two sets of racks 902. The two sets of guide rods 908 are fixedly installed inside the fixed frame 4. Short plates 906 are fixedly installed on both sides of the two sets of connecting blocks 903. The four sets of short plates 906 are slidably installed inside the two sides of the fixed frame 4. A pointer 907 is fixedly installed on the top of the four sets of short plates 906. The two sets of pointers 907 on the same side are respectively located at the bottom of the corresponding scale 5 to facilitate observation of the width of the packaging film to be cut.

[0022] In this embodiment, gear 901 is rotatably mounted on the top inner wall of the fixed frame 4. Motor 2 11 is fixedly mounted on the top of the fixed frame 4, and the output shaft of motor 2 11 is fixedly connected to gear 901.

This causes the two sets of connecting blocks 903 to move the short plates 906 and pointers 907 on both sides relative to each other. Then, by observing the pointers 907 and the scale 5, the width of the packaging film to be cut can be adjusted.
