Description

Technical Field

[0001] The utility model relates to the technical field of membrane material processing, in particular to a cutting structure for processing architectural membrane materials. Background Art

[0002] Architectural membrane, also known as "tensile membrane", is an emerging building material. It has been recognized as the "sixth building material" after brick, stone, concrete, steel and wood. Membrane material is a thin film material with strength and good flexibility. It is made of fibers woven into a fabric base material, and the base material is fixed with resin as a coating material on both sides. The central fabric base material is divided into polyester fiber and glass fiber. After the processing and winding of the architectural membrane is completed, a cutting structure will be used for cutting operation.

The utility model discloses a cutting device for processing PTFE membrane materials, which relates to the field of membrane material processing, including a cutting table, a mounting plate is provided above the cutting table, and connecting plates are provided at both ends of the mounting plate, and the mounting plate and the connecting plate are both arranged in a "冂"-shaped structure, and the bottom two ends of the connecting plate are fixedly connected to the mounting plate by fixing screws. The utility model is provided with a detachable connecting plate at both ends of the mounting plate, and the motor on the connecting plate cooperates with the reciprocating screw to drive the slider to move, thereby driving the cutting knife on the slider to cut the membrane material, and the pressing plate on the mounting plate cooperates with the damping layer thereon to press the membrane material to limit it, thereby improving the efficiency and speed of cutting, and the cutting knife is arranged as a detachable structure, so that the cutting knife can be quickly disassembled and replaced when damaged, thereby improving the working efficiency of the device.

[0004] The existing architectural membrane material cutting structure is not equipped with a mechanism for sharpening the cutting blade. After long-term use of cutting architectural membrane materials, the sharpness of the cutting blade will be greatly reduced, which will not only affect the quality of subsequent cutting of architectural membrane materials, but also require frequent replacement of the cutting blade in large-scale processing, thereby reducing processing efficiency. Therefore, a cutting structure for architectural membrane material processing is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a cutting structure for processing architectural membrane materials, aiming to solve the problem that the architectural membrane material cutting structure is not provided with a mechanism for sharpening the cutting knife. After long-term use of cutting architectural membrane materials, the sharpness of the cutting knife will be greatly reduced, which will not only affect the quality of subsequent cutting of architectural membrane materials, but also require frequent replacement of the cutting knife in large-scale processing, thereby reducing processing efficiency.

[0006] To achieve the above object, the cutting structure for building membrane material processing proposed by the present utility model includes a connecting frame. A chute is provided at the top of the connecting frame. A moving structure is arranged inside the chute. A cutting knife is bolted to the bottom of the moving structure. A lifting structure is arranged at the rear side of the bottom of the connecting frame. A double-sided grinding mechanism is arranged at the front side of the lifting structure. The double-sided grinding mechanism is located outside the cutting knife. A secondary pressing structure is arranged at the bottom of the double-sided grinding mechanism;

[0007] The double-sided grinding mechanism includes a first motor, a bidirectional lead screw, a fixed rod, a fixed block, an outer plate, a grinding sheet and a moving block. The first motor is embedded in the front side of the lifting structure. The bidirectional lead screw is bolted to the output end of the first motor. The fixed rod is fixedly connected to the left side of the front side of the lifting structure. The fixed block is slidably connected to the front side and the rear side of the surface of the fixed rod. The outer plate is fixedly connected to the inner side of the fixed block. The grinding sheet is bolted to the inner side of the outer plate. The grinding sheet is located outside the cutting knife. The moving blocks are respectively threadedly connected to the front side and the rear side of the surface of the bidirectional lead screw. The inner side of the moving block is fixedly connected to the outer side of the outer plate.

[0008] Preferably, the moving structure includes a second motor bolted to the left side of the connecting frame. The output end of the second motor penetrates through the left side of the connecting frame and extends into the chute. A threaded rod is bolted to the output end of the second motor. The right side of the threaded rod is rotatably connected to the right side inside the chute. A moving block is threadedly connected to the surface of the threaded rod. The bottom of the moving block is bolted to the top of the cutting knife.

[0009] Preferably, the lifting structure includes electric telescopic rods bolted to both sides of the bottom of the connecting frame. A lifting rod is bolted to the telescopic end of the electric telescopic rod. The inside of the front side of the lifting rod is embedded and connected to the first motor.

[0010] Preferably, the secondary pressing structure includes a groove opened on the outer side of the outer plate. Rotating columns are rotatably connected to both sides inside the groove. A secondary pressing shaft is rotatably connected to the inner sides of the rotating columns.

[0011] Preferably, mounting blocks are fixedly connected to both sides of the rear side of the connecting frame. Mounting holes are opened on the tops of the mounting blocks.

[0012] Preferably, a secondary sliding rod is bolted to the middle of the top of the lifting rod. The top of the secondary sliding rod penetrates through the bottom of the connecting frame.

[0013] Preferably, a positioning disk is fixedly connected to the top of the secondary sliding rod. The positioning disk is located on the top of the connecting frame.

[0014] Preferably, a limiting disk is bolted to the front side of the fixed rod. The limiting disk is located in front of the front fixed block.

[0015] In the technical solution of the present utility model, by setting a double-sided grinding mechanism and an auxiliary pressing structure, and installing its connecting frame to the cutting table, when cutting building membrane materials, according to the preset cutting path or actual processing requirements, the moving structure drives the cutting knife to move flexibly within the top plane of the connecting frame, so as to realize the cutting of the building membrane materials processed by the cutting table. When the sharpness of the cutting knife decreases after long-term use, the lifting structure lowers the double-sided grinding mechanism and the auxiliary pressing structure, and then starts the first motor embedded on the front side of the lifting structure. The first motor serves as a power source, and its output end drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the moving blocks threadedly connected to the front side and the rear side of its surface to generate relative linear motion. While the moving blocks are moving, the fixed rod and the fixed block slidably connected thereto play a role of fixing and guiding. The fixed block is fixedly connected to the outer plate, restricting the movement of the outer plate in other directions except the axial direction of the bidirectional lead screw, ensuring that the outer plate can only move linearly along the direction of the fixed rod with the moving block. As the moving block moves, the outer plate and the grinding pieces bolted to its inner side also move accordingly. By the forward and reverse rotation of the bidirectional lead screw, the outer plates and the grinding pieces on the front and rear sides can be controlled to approach each other, thereby clamping the cutting knife in the middle. Then, during the cutting movement of the cutting knife, it will repeatedly pass through the grinding pieces, and the grinding pieces can simultaneously grind the two sides of the cutting knife, restoring the sharpness of the cutting knife, without the need to frequently replace the cutting knife, ensuring the quality and processing efficiency of subsequent cutting of building membrane materials. At the same time, the auxiliary pressing structure is located at the bottom of the double-sided grinding mechanism. During the grinding process of the cutting knife, the auxiliary pressing structure can apply a certain pressure to the building membrane material, thereby ensuring the stability of the cutting knife when cutting the building membrane material.

[0028] The utility model provides a cutting structure for building membrane material processing, aiming to solve the problem that the cutting structure of building membrane material does not have a mechanism for grinding the cutting scissors. After long-term use of cutting the building membrane material, the sharpness of the cutting scissors will be greatly reduced, which will not only affect the quality of subsequent cutting of the building membrane material, but also require frequent replacement of the cutting scissors in the state of large-scale processing, thus reducing the processing efficiency.

[0029] As Figures 1-5 shown, the cutting structure for building membrane material processing provided by the embodiment of the utility model includes a connecting frame 1. A chute 2 is opened at the top of the connecting frame 1. A moving structure 3 is arranged inside the chute 2. A cutting scissors 4 is bolted to the bottom of the moving structure 3. A lifting structure 5 is arranged at the rear side of the bottom of the connecting frame 1. A double-sided grinding mechanism 6 is arranged at the front side of the lifting structure 5. The double-sided grinding mechanism 6 is located outside the cutting scissors 4. A secondary pressing structure 7 is arranged at the bottom of the double-sided grinding mechanism 6;

[0030] The double-sided grinding mechanism 6 includes a first motor 601, a bidirectional lead screw 602, a fixed rod 603, a fixed block 604, an outer plate 605, a grinding piece 606 and a moving block 607. The first motor 601 is embedded in the front side of the lifting structure 5. The bidirectional lead screw 602 is bolted to the output end of the first motor 601. The fixed rod 603 is fixedly connected to the left side of the front side of the lifting structure 5. The fixed block 604 is slidably connected to the front side and the rear side of the surface of the fixed rod 603. The outer plate 605 is fixedly connected to the inner side of the fixed block 604. The grinding piece 606 is bolted to the inner side of the outer plate 605. The grinding piece 606 is located outside the cutting scissors 4. The moving blocks 607 are respectively threadedly connected to the front side and the rear side of the surface of the bidirectional lead screw 602. The inner side of the moving block 607 is fixedly connected to the outer side of the outer plate 605.

[0031] In the technical solution of the utility model, by setting the double-sided grinding mechanism 6, during the processing of the building membrane material, after the cutting scissors 4 cut, the double-sided grinding mechanism 6 can timely grind the cutting edge. The grinding piece 606 is located outside the cutting scissors 4, and can quickly process the cutting edge of the membrane material after cutting, removing uneven parts such as burrs, thereby significantly improving the cutting quality. The first motor 601 drives the bidirectional lead screw 602 to rotate, so that the moving block 607 moves on the bidirectional lead screw 602, and then drives the outer plate 605 and the grinding piece 606 to move. This design can realize precise grinding of building membrane materials with different widths, adapt to different specifications of cutting requirements, and improve the efficiency and flexibility of grinding. The setting of the fixed rod 603 and the fixed block 604 provides stable support for the outer plate 605, ensuring that the grinding piece 606 maintains a stable position during the working process, thus ensuring the consistency and reliability of the grinding effect.

[0032] Among them, please refer to Figure 2, the moving structure 3 includes a second motor 301 bolted to the left side of the connecting frame 1. The output end of the second motor 301 penetrates through the left side of the connecting frame 1 and extends into the interior of the chute 2. A threaded rod 302 is bolted to the output end of the second motor 301. The right side of the threaded rod 302 is rotatably connected to the right side inside the chute 2. A moving block 303 is threadedly connected to the surface of the threaded rod 302. The bottom of the moving block 303 is bolted to the top of the cutting scissors 4. In this embodiment, by setting the moving structure 3, the second motor 301 drives the threaded rod 302 to rotate, causing the moving block 303 threadedly connected to the surface of the threaded rod 302 to move within the chute 2, thereby driving the cutting scissors 4 to move. This design can precisely control the position of the cutting scissors 4, meet the cutting requirements at different positions, and improve the flexibility and accuracy of cutting.

[0033] Further, please continue to refer to Figure 3 , the lifting structure 5 includes electric telescopic rods 501 bolted to both sides of the bottom of the connecting frame 1. The telescopic ends of the electric telescopic rods 501 are bolted to lifting rods 502. The first motor 601 is embedded inside the front side of the lifting rod 502. In this embodiment, by setting the lifting structure 5, the electric telescopic rods 501 can drive the lifting rods 502 to move up and down, thereby adjusting the height of the double-sided grinding mechanism 6, enabling the double-sided grinding mechanism 6 to descend when grinding the cutting scissors 4 and ascend when not in use, thus facilitating use.

[0034] Please continue to refer to Figure 4 , the auxiliary pressing structure 7 includes a groove 701 opened on the outer side of the outer plate 605. Rotating columns 702 are rotatably connected to both sides inside the groove 701. An auxiliary pressing shaft 703 is rotatably connected to the inner sides of the rotating columns 702. In this embodiment, by setting the auxiliary pressing structure 7, the auxiliary pressing shaft 703 can roll on the surface of the membrane material, playing an auxiliary pressing role on the building membrane material, preventing the membrane material from shifting during the cutting and grinding processes, ensuring the precision of cutting and grinding. The rotational design of the rotating columns 702 and the auxiliary pressing shaft 703 reduces the friction with the surface of the membrane material and reduces the risk of damage to the membrane material.

In this embodiment, by setting the mounting blocks 8, the mounting holes on the mounting blocks 8 can conveniently fix the entire cutting structure in the working position, ensuring the stability of the equipment during the working process. At the same time, according to different working environments and requirements of the cutting table, a suitable mounting position can be selected, improving the applicability of the equipment.

[0036] In addition, please refer to Figure 3, a secondary sliding rod 9 is bolted in the middle of the top of the lifting rod 502, and the top of the secondary sliding rod 9 penetrates through the bottom of the connection frame 1. In this embodiment, by providing the secondary sliding rod 9, the secondary sliding rod 9 plays a guiding and stabilizing role during the lifting and lowering process of the lifting rod 502, preventing the lifting rod 502 from shaking or deviating, and ensuring the smooth operation of the lifting structure 5.

[0037] In addition, please refer to Figure 3 , a positioning disk 10 is fixedly connected to the top of the secondary sliding rod 9, and the positioning disk 10 is located on the top of the connection frame 1. In this embodiment, by providing the positioning disk 10, the positioning disk 10 located on the top of the connection frame 1 can limit the lowering height of the secondary sliding rod 9, providing safety protection for the operation of the overall structure and avoiding safety accidents caused by operation errors.
