Technical Field
[0001] This utility model belongs to the field of dustproof film cutting, and specifically relates to a cutting device for dustproof film. Background Technology
[0002] Traditional cutting devices have some problems in the process of cutting dustproof films. On the one hand, traditional devices lack effective guiding and fixing devices, and the film is prone to deviation during the cutting process; for example, the film may deviate from the predetermined cutting path due to uneven tension or equipment vibration, resulting in uneven cutting edges, which in turn leads to inconsistent film width and affects the appearance and use of the product.
[0003] On the other hand, traditional cutting devices generally use manual feeding, which is inefficient, cannot meet the needs of large-scale production, and poses certain safety hazards.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a cutting device for dustproof film. By using a feeding guide groove in conjunction with a feeding component, the device achieves precise guidance of the film at a lower cost. At the same time, by setting up a film guiding and gathering component, the film is gathered, which increases the strength of material conveying and improves the stability of feeding.
[0006] Technical Solution: To achieve the above objectives, this utility model provides a cutting device for dustproof films, including a frame, a cutting assembly, and a feeding assembly; the cutting assembly is located at one end of the frame; the cutting assembly includes a cutting mounting frame, a set of guide columns, a cutting cylinder, a cutting plate, and a blade; the cutting mounting frame is located at one end of the frame; the guide columns are located between the upper and lower ends of the cutting mounting frame; the cutting cylinder is located at the upper end of the cutting mounting frame; the cutting plate is located on the guide columns and connected to the output end of the cutting cylinder; the blade is located on one side of the cutting plate; the feeding assembly is located on the frame and is situated beside the cutting mounting frame; the frame is also provided with a feeding guide groove; the feeding guide groove passes through the bottom of the feeding assembly and extends to the bottom of the blade; a film guiding and gathering member is provided at the end of the feeding guide groove away from the cutting assembly. The guide column provides a stable up-and-down movement path for the cutting plate, and the cutting cylinder provides the cutting power. Through the control of the cutting cylinder, the blade can accurately perform the cutting action, ensuring the accuracy and consistency of the cutting action. The feeding assembly, feeding guide groove and film guiding and gathering component work together to realize the automated feeding process, reducing the tediousness and error of manual operation, reducing production interruption and defect rate caused by human factors, and improving production efficiency and product quality. The film guiding and gathering component gathers the film to be cut into a bundle, increasing the strength of the film along the conveying direction, and ensuring the flatness and stability of the film during conveying and cutting.
[0007] Furthermore, the feeding assembly includes a cylinder mounting bracket, a set of rotary cylinders, and a feeding roller; the cylinder mounting bracket is mounted on a platform; the rotary cylinders are horizontally opposite each other and located inside the cylinder mounting bracket; the feeding roller is positioned between the output ends of the rotary cylinders; the feeding roller is axially perpendicular to the feeding guide groove. The rotary cylinders can precisely control the rotation of the feeding roller; the feeding roller ensures that the film remains stable during transport, reducing vibration and shaking of the film during transport; simultaneously, the axial direction of the feeding roller is perpendicular to the feeding guide groove, ensuring that the film can pass through the feeding guide groove evenly, further improving cutting accuracy.
[0008] Furthermore, a material placement roller is provided at the end of the frame away from the cutting component. The film to be cut is wound around the material placement roller to ensure the stability of the film and facilitate subsequent feeding.
[0009] Furthermore, the material placement roller is positioned slightly below the upper surface of the platform, reducing the friction required for feeding and ensuring that the film can be fed smoothly under the drive of the feeding assembly.
[0010] Furthermore, a cutting opening is provided between the guide posts; the cutting opening is located directly below the blade. The cutting opening provides space for the blade to cut, and also facilitates collection after cutting.
[0011] Furthermore, the blade has a cutting edge on the side away from the feeding assembly. After the cutting edge of the blade contacts the film to complete the cut, the non-cutting surface of the blade then contacts the film, turning the cut film downwards and pressing it into the cut opening for easy collection.
[0012] Furthermore, the feeding guide groove is provided with several pressure plates. The pressure plates are used to prevent the film from unraveling from its bundle shape, which would cause the film to lose its strength in the conveying direction and affect the smooth conveying process.
[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0014] 1. This utility model provides a cutting device for dustproof film, which achieves precise guidance of the film at a low cost by using a feeding guide groove in conjunction with a feeding assembly;
[0015] 2. This utility model provides a cutting device for dustproof films. By setting up a film guiding and gathering component, the film is gathered, which increases the strength of material conveying and improves the stability of feeding. Attached Figure Description

[0042] This utility model discloses a cutting device for dustproof film. The dustproof film to be cut is rolled up and placed on the material placing roller 4. The film is passed through the film guide and gathering member 12, and then the bundled film is placed in the feeding guide groove 11, manually pulled to the feeding roller 33, and pressed by the pressure plate 13.
[0043] Start the rotary cylinder 32 to drive the feeding roller 33 to rotate, and drive the bundled film to the cutting port 26 along the feeding guide groove 11. The cutting cylinder 23 drives the blade 25 to complete the cutting. The cut dustproof film falls into the cutting port 26 and is collected below.
[0044] The above description is only a preferred embodiment of the present utility model.
