DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-3The utility model provides a technical solution: a slitting device for mask production, including a base 1, the top of the base 1 is connected to a plurality of conveying rollers 2 through a driving mechanism, and a frame 3 is provided on the top of the base 1, and a hydraulic cylinder 4 is fixedly installed on the top plate of the frame 3 by bolts, and the output end of the hydraulic cylinder 4 passes through the interior of the frame 3 and is connected and installed with a cutting knife 5, and a cleaning mechanism 8 is provided between the side plates of the frame 3 in a front-to-back symmetrical distribution, the cleaning mechanism 8 is composed of a horizontal frame 81 and a cleaning block 82, and a pressing mechanism 9 is provided on the middle outer side of the cleaning mechanism 8, and the pressing mechanism 9 is composed of a cylinder 91, an angle frame 92, a push plate 93, a pressure rod 94, a spring 95 and a pressure plate 96. When the cutting knife 5 is driven downward by the hydraulic cylinder 4 to cut, During operation, the conveying roller 2 continuously conveys the mask material through the driving mechanism to ensure that the material enters the cutting area smoothly, and the horizontal frame 81 in the cleaning mechanism 8 adjusts the cleaning block 82 to a suitable position so that the cleaning block 82 can be in friction contact with the surface of the cutting knife 5. The cleaning block 82 can effectively scrape off any residual substances that may adhere to the surface of the cutting knife 5, keeping the cutting knife 5 clean. At the same time, the cylinder 91 in the pressing mechanism 9 is started to push the push plate 93 to move vertically on the angle frame 92. The push plate 93 further drives the pressure rod 94 to press down, so that the pressure plate 96 is tightly attached to the position just cut under the elastic force provided by the spring 95, forming an immediate pressing effect, ensuring that the layers of mask material can be quickly fixed after cutting to avoid stratification. Occurs, thereby improving the cleanliness of the cutting process and enhancing the quality and consistency of the finished mask products. A positioning column 6 is fixed on the inner wall of the side plate of the frame 3 through two support blocks, and a positioning sleeve 7 is welded and fixed at both ends of the horizontal frame 81 through a connecting piece, and the positioning sleeve 7 is sleeved on the outside of the positioning column 6 and fixed by screws. This structure can accurately adjust the gap between the two horizontal frames 81 by adjusting the position of the positioning sleeve 7 on the positioning column 6 and fixing it with screws, thereby ensuring that the cleaning block 82 can properly contact the cutting knife 5 and perform effective cleaning work, thereby improving the accuracy and efficiency of the cutting process. The cleaning blocks 82 are all bonded and fixed to the inner side of the horizontal frame 81, and the gap formed between the cleaning blocks 82 corresponds to the position of the cutting knife 5. This structure When the cutting knife 5 moves downward to perform the cutting operation, the horizontal frame 81 can ensure that the cleaning block 82 is in precise contact with the surface of the cutting knife 5. The friction of the cleaning block 82 effectively removes the residue on the cutting knife 5 and keeps the cutting knife 5 clean. The cleaning block 82 can be made of a material with a certain hardness but will not damage the surface of the cutting knife 5, such as high-density polyethylene (HDPE), nylon or other wear-resistant plastics. These materials can effectively scrape off the residue on the surface of the cutting knife 5 without causing scratches or other damage to it. The cylinder 91 is fixed to the middle of the outer side of the horizontal frame 81 by bolts, and the angle frame 92 is welded and fixed to the middle of the bottom end of the horizontal frame 81. The push plate 93 and the pressure plate 96 are respectively arranged on the upper and lower sides of the bottom end of the angle frame 92, and the pressure rod 94 is provided with three.The pressure rod 94 is evenly connected between the push plate 93 and the pressing plate 96 and is movably connected to the bottom end portion of the corner bracket 92. There are two springs 95, and the springs 95 are connected between the bottom surface of the push plate 93 and the top surface of the bottom end portion of the corner bracket 92. In this structure, the action of the air cylinder 91 pushes the push plate 93 to move downward, and then drives the pressing plate 96 to closely adhere to the cut mask material by sliding the pressure rod 94 on the bottom end portion of the corner bracket 92. The elastic action of the spring 95 ensures that the pressing plate 96 stably applies pressure, enabling the cut mask material to be immediately pressed, enhancing the adhesion strength between the layers of fabric, and preventing delamination. The pressing plate 96 is integrally in a strip-shaped rectangular structure, and a protective pad is adhesively fixed to the bottom surface of the pressing plate 96. In this structure, when the pressing plate 96 performs a pressing operation driven by the air cylinder 91, it can contact the cut mask material through the protective pad, avoiding direct compression of the material by the rigid pressing plate 96 and causing damage. At the same time, the protective pad can also increase the friction force of the contact surface, ensuring that the pressing plate 96 can firmly press the material. The top of the cutting knife 5 is fixedly installed with a tool holder through bolts, and the top of the tool holder of the cutting knife 5 is symmetrically connected with a guide shaft 10 through a threaded interface. The upper end of the guide shaft 10 is slidably connected to the top end of the frame 3. In this structure, when the cutting knife 5 performs a cutting operation, it can synchronously drive the guide shaft 10 to slide up and down, ensuring the linearity and stability of the cutting path. At the same time, the sliding connection between the guide shaft 10 and the frame 3 ensures the smooth movement of the cutting knife 5 and reduces the shaking during the cutting process.
[0018] Working principle: When using the slitting device for mask production, first, the position of the positioning sleeve 7 on the positioning column 6 can be adjusted and fixed with screws to accurately adjust the gap between the two horizontal frames 81. When the hydraulic cylinder 4 drives the cutting knife 5 to push downward for cutting operation, at this time, the conveying roller 2 continuously conveys the mask material through the driving mechanism, enabling the material to smoothly enter the cutting area. At this time, the process of the cutting knife 5 working will contact the cleaning block 82, and the residues on the cutting knife 5 can be effectively removed through the friction of the cleaning block 82. At the same time, the air cylinder 91 is started. The air cylinder 91 starts to push the push plate 93 to move vertically on the corner bracket 92. The push plate 93 drives the pressure rod 94 to press down, so that the pressing plate 96 closely adheres to the just-cut position under the elastic force provided by the spring 95. At the same time, the protective pad on the bottom surface of the pressing plate 96 contacts the cut mask material, ensuring that the pressing plate 96 can more firmly press the material, thus completing a series of operations.
[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
