[0001] This utility model relates to the field of breathable membrane technology, and in particular to an antibacterial breathable membrane cutting mechanism. Background Technology

[0002] Antibacterial and breathable membranes, which combine antibacterial and breathable properties, are widely used in medical protection, food packaging, industrial filtration and other fields. The precision of their cutting and processing directly affects the performance and stability of subsequent products.

[0003] A search revealed a cutting device for antibacterial folded film, patent application number 202222243477.5 on the Chinese Patent Network. In use, the folded film to be cut is placed on the surface of the cutting table. The movable end of the telescopic component moves the frame plate towards the cutting table, and the limiting plate first contacts the folded film on the cutting table surface. The cutting table supports the folded film, and the limiting plate presses down on it, reducing the possibility of movement during cutting and improving the stability of the folded film during cutting, making it less prone to deformation of the cut edge. However, the above device has the following problems: the remaining film after cutting needs to be manually pulled to the next cutting position, which not only increases the labor intensity of the operator, but also easily causes uneven force, resulting in film stretching deformation or positional displacement, affecting the subsequent cutting dimensional accuracy.

[0004] To address the above problems, this utility model proposes an antibacterial and breathable membrane cutting mechanism. Utility Model Content

[0005] Based on the existing technical problems of uneven manual force causing membrane displacement and stretching deformation, which affects the subsequent cutting accuracy, this utility model proposes an antibacterial and breathable membrane cutting mechanism.

[0006] This utility model proposes an antibacterial and breathable membrane cutting mechanism, including a cutting table, a roller shaft at one end of the cutting table, a breathable membrane wound around the surface of the roller shaft, an auxiliary mechanism at the other end of the cutting table, a gantry frame on the outside of the cutting table, a laser cutting head slidably connected to the lower side of the gantry frame, and grooves on both sides of the cutting table.

[0007] Preferably, the auxiliary mechanism includes an electric telescopic rod symmetrically arranged inside the cutting table. One end of the electric telescopic rod is fixedly connected to the inner wall of the cutting table, and the other end of the electric telescopic rod is fixedly connected to a push rod. A column is symmetrically arranged on the upper surface of the push rod along the length direction of the cutting table. A circular groove adapted to the surface of the column is opened at the upper end of the cutting table, and the surface of the column is slidably connected to the inner wall of the circular groove.

[0008] Preferably, auxiliary rods are rotatably connected to both ends of the push rod, and a rotating rod is rotatably connected to one end of the auxiliary rod. T-shaped blocks are symmetrically fixed to both sides of the cutting table. The upper end of the T-shaped block is rotatably connected to the inner wall of the rotating groove opened in the rotating rod body. A circular pressure block is fixedly connected to one end of the rotating rod, and another pressure block is also fixedly connected to the upper end of the column.

[0009] Preferably, the inner wall of the slide groove is provided with a straight slide rail, and a pneumatic gripper is fixedly connected to the upper end of the slider of the straight slide rail, and a clamping block is fixedly connected to the clamping part of the pneumatic gripper.

[0010] Preferably, the clamping surface of the clamping block is provided with anti-slip texture.

[0011] Preferably, a silicone cushioning pad is fixedly attached to the lower surface of the circular pressure block, and the lower surface of the silicone cushioning pad has an array of micro anti-slip grooves.

[0012] The beneficial effects of this utility model are as follows:

[0013] By setting up an auxiliary mechanism, the electric telescopic rod drives the push rod, which in turn drives the pressure blocks on the column and rotating rod to simultaneously press the membrane. In conjunction with the pneumatic clamp on the straight slide rail, the remaining breathable membrane after cutting can be automatically stretched to the designated position without manual traction, reducing operation steps and improving efficiency. The silicone buffer pad of the pressure block can prevent membrane damage, and the anti-slip texture of the clamping block can prevent stretching slippage, ensuring stretching accuracy, reducing membrane displacement, and improving the consistency of cutting dimensions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 An antibacterial and breathable membrane cutting mechanism includes a cutting table 1, a roller 2 at one end of the cutting table 1, a breathable membrane 3 wound around the surface of the roller 2, an auxiliary mechanism 4 at the other end of the cutting table 1, a gantry frame 5 on the outside of the cutting table 1, a laser cutting head 6 slidably connected to the lower side of the gantry frame 5, and grooves 10 on both sides of the cutting table 1.

[0021] In this embodiment, the auxiliary mechanism 4 includes an electric telescopic rod 41 symmetrically arranged inside the cutting table 1. One end of the electric telescopic rod 41 is fixedly connected to the inner wall of the cutting table 1, and the other end of the electric telescopic rod 41 is fixedly connected to a push rod 42. A column 43 is symmetrically arranged on the upper surface of the push rod 42 along the length direction of the cutting table 1. A circular groove adapted to the surface of the column 43 is opened at the upper end of the cutting table 1. The surface of the column 43 is slidably connected to the inner wall of the circular groove.

[0022] Specifically, the electric telescopic rod 41 is a small industrial-grade telescopic rod with a stroke of 50-100mm and a thrust of 100-200N. Its telescopic speed can be adjusted within the range of 5-10mm / s by the control system to adapt to the pressing requirements of breathable membranes 3 of different thicknesses. The inner diameter of the circular groove is 0.1mm larger than the outer diameter of the column 43, which ensures that the column 43 slides smoothly up and down without jamming, and also restricts the lateral displacement of the column 43, ensuring that the column 43 drives the pressure block 47 to accurately press into the middle area of ​​the breathable membrane 3, providing stable central support for the membrane.

[0023] In this embodiment, auxiliary rods 44 are rotatably connected to both ends of push rod 42, and a rotating rod 45 is rotatably connected to one end of auxiliary rod 44. T-shaped blocks 46 are symmetrically fixedly connected to both sides of cutting table 1. The upper end of T-shaped block 46 is rotatably connected to the inner wall of the rotating groove opened in the body of rotating rod 45. A circular pressure block 47 is fixedly connected to one end of rotating rod 45, and another pressure block 47 is also fixedly connected to the upper end of column 43.

[0024] Specifically, the auxiliary rod 44 is rotatably connected to the push rod 42 and the rotating rod 45 via pins to ensure that there is no loosening or abnormal noise during linkage; the upper end of the T-shaped block 46 is a hollow horizontal cylindrical structure, which is interference-fitted with the rotating groove of the rotating rod 45 to prevent the rotating rod 45 from shaking; the diameter of the pressure block 47 is set to 20-30mm, and the pressure block on the column 43 and the pressure block on the rotating rod 45 are aligned vertically to prevent the film from shaking at the end during cutting.

[0025] In this embodiment, the inner wall of the slide groove 10 is provided with a straight slide rail 410, and the upper end of the slider of the straight slide rail 410 is fixedly connected to a pneumatic gripper 48. The gripping part of the pneumatic gripper 48 is fixedly connected to a clamping block 49.

[0026] Specifically, the straight slide rail 410 is a linear precision guide rail with a length consistent with the cutting table 1. The slider movement accuracy can reach ±0.05mm, ensuring accurate feeding position. The pneumatic gripper 48 adopts a double-finger cylinder, and the clamping force can be adjusted by the air pressure valve, which is compatible with a 0.1-1mm thick breathable membrane 3. The clamping block 49 is fixed to the fingers of the pneumatic gripper 48 by screws, which facilitates the replacement of worn clamping blocks 49 in the future.

[0027] In this embodiment, the clamping surface of the clamping block 49 is provided with anti-slip texture.

[0028] Specifically, the anti-slip texture is a diamond-shaped concave-convex structure with a texture depth of 0.2-0.3mm and a texture spacing of 1mm. The texture is formed by laser engraving, and the surface is smooth and burr-free. It can increase the friction between the clamping block 49 and the breathable membrane 3 while avoiding scratching the antibacterial coating on the membrane surface. Especially for the slightly smooth breathable membrane 3, the anti-slip texture can effectively prevent the membrane from slipping during stretching and feeding, control the feeding deviation within ±0.1mm, and ensure the consistency of cutting dimensions.

[0029] In this embodiment, a silicone cushioning pad is fixedly attached to the lower surface of the circular pressure block 47, and the lower surface of the silicone cushioning pad is arrayed with micro anti-slip grooves.

[0030] Specifically, the silicone cushioning pad is made of food-grade silicone with a Shore hardness of 30-40HA and a thickness of 0.8-1.2mm. It has good elasticity and wear resistance, which can prevent the micropores from being squeezed and deformed due to direct contact between the rigid pressure block 47 and the membrane. The micro anti-slip grooves are distributed in a circular groove array, which can further enhance the anti-slip effect between the pressure block and the membrane, reduce the contact area between the cushioning pad and the membrane, avoid the accumulation of micro-heat generated by laser cutting that could damage the membrane, and facilitate the separation of the membrane from the pressure block after cutting.

[0031] principle:

[0032] In use, the electric telescopic rod 41 drives the push rod 42 to move downward, which in turn drives the column 43 to slide downward along the circular groove. At the same time, the two ends of the push rod 42 pull the rotating rod 45 through the auxiliary rod 44, causing the rotating rod 45 to rotate around the cylindrical end of the T-shaped block 46. Finally, the circular pressure block 47 at the end of the rotating rod 45 moves closer to the membrane surface and presses it, achieving synchronous pressing. Then, the laser cutting head 6 is used to cut the breathable membrane 3. The operator takes out the cut mold body. At this time, the electric telescopic rod 41 returns to its original position, and the slider of the straight slide rail 410 drives the pneumatic clamp 48 to slide along the slide rail. As groove 10 slides, the synchronous roller 2 rotates at the speed of the straight slide rail 410 under the rotation of the external drive device, causing the end of the breathable membrane 3 to move towards the pressure block 47. When the mold of the breathable membrane 3 is located between the pressure blocks 47, the pneumatic clamp 48 drives the clamp 49 to open, releasing the clamping effect on the mold. The slider of the straight slide rail 410 drives the pneumatic clamp 48 to return to its initial position. The pneumatic clamp 48 does not contact the membrane during the movement. The electric telescopic rod 41 extends again, thereby driving the pressure block 47 to press the breathable membrane 3, which facilitates subsequent cutting.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
