Description

Technical Field

[0001] This utility model belongs to the field of filter cloth technology, specifically relating to a cutting device for woven filter cloth. Background Technology

[0002] Woven filter cloth, as a traditional filter material, has a development history closely linked to industrial progress. Early woven filter cloths were primarily made from natural fibers such as cotton, wool, and jute. Due to the availability of raw materials and their inherent filtration properties, they were initially used for ventilation filtration in textile mills and mines, as well as for liquid filtration in the food, chemical, and pharmaceutical industries. With the development of the chemical industry, chemical fibers such as polyester, polyamide, and polyacrylonitrile gradually became the main raw materials for woven filter cloths. The application of these chemical fiber materials significantly improved the chemical resistance and mechanical and physical properties of the filter cloths, enabling them to meet the demands of more complex industrial environments.

[0003] Chinese patent CN205077305U discloses a cutting device for woven filter cloth. A lifting cylinder controls the laser cutting head to descend, so that the nozzle of the laser cutting head is 10mm-15mm away from the woven filter cloth. The laser cutting head begins to cut the woven filter cloth. The moving table moves along the Y-axis on the machine tool and controls the laser cutting head to move in the same direction to cut the woven filter cloth longitudinally. The machine tool controls the moving table to move along the X-axis on the roller bed to cut the woven filter cloth transversely.

[0004] Currently, filter cloths widely used in industrial production typically require manual removal from the cutting equipment by operators after the mechanical cutting process. However, with the continuous improvement of modern industrial automation, especially the rapid development of CNC technology and intelligent control systems, the operating speed of filter cloth cutting equipment has significantly increased. This technological advancement has greatly improved the efficiency of the cutting process. However, in stark contrast, the subsequent manual material handling process remains a traditional manual operation. Due to inherent physiological limitations of human operation, the speed of manual material handling cannot keep up with the high-speed cutting equipment. This speed imbalance between production stages severely restricts the overall efficiency of the filter cloth cutting process, creating a significant production bottleneck. This efficiency mismatch not only affects the overall output of the production line but also, to some extent, restricts further increases in enterprise capacity. Utility Model Content

This precise matching design ensures both cutting accuracy and improved work efficiency. The entire assembly system is meticulously designed, with the interrelationships between components considering both functional requirements and ease of operation.

[0022] As a preferred embodiment, a first mounting plate 11 is fixedly installed on one side of the cutting table 1. This first mounting plate 11 is made of metal, providing high structural strength and stability. Two first bearing seats 12 are precisely and symmetrically installed on the top plane of the first mounting plate 11. These bearing seats 12 are of standard industrial specifications, ensuring installation accuracy and operational reliability. Between the two first bearing seats 12, a rotating roller 13 is rotatably fitted using a precision fit. This roller 13 is made of high-quality steel and its surface has undergone special treatment to ensure wear resistance and smooth rotation. A filter cloth 14 is securely installed on the outer circumference of the roller 13. One end of the filter cloth 14 is free. This filter cloth 14 is woven from a special high-temperature resistant and corrosion-resistant material, effectively filtering debris and dust generated during the cutting process. The entire device has a reasonable structural design, with all components fitting tightly, ensuring the stability and efficiency of the cutting operation.

[0023] As a preferred option, a second mounting plate 15 is securely mounted on the side wall of the cutting table 1 using multiple high-strength screws. This mounting plate is made of high-quality steel and has excellent load-bearing capacity. The top of the second mounting plate 15 is precision-machined to achieve extremely high flatness, and a high-power motor 16 is firmly mounted on it. The output shaft of the motor 16 is tightly connected to the drive shaft of the first conveyor roller 3 via a coupling. A precision transmission component 17 is installed between the first conveyor roller 3 and the second conveyor roller 4. This component includes a gear transmission system and a synchronous belt drive device to ensure synchronous operation between the two rollers. The entire transmission system has a reasonable layout, runs smoothly, and can effectively guarantee the continuity and stability of material conveying.

[0024] As a preferred option, both ends of the first conveyor roller 3 are rotatably supported by precision-machined second bearing seats 18. These second bearing seats 18 are made of high-quality steel and are securely mounted on the side wall of the cutting table 1 using high-strength bolts. Similarly, both ends of the second conveyor roller 4 are also equipped with second bearing seats 18 of the same specifications. These bearing seats, after precise adjustment, are firmly installed in predetermined positions on the second mounting plate 15. The installation positions of the two sets of bearing seats are strictly calibrated to ensure that the conveyor rollers remain horizontal during operation, providing stable and reliable support for material conveying. This double-bearing seat support structure not only improves the operational stability of the equipment but also significantly extends the service life of the conveyor rollers.

[0025] As a preferred embodiment, the transmission component 17 is further composed of three key components: a first synchronous pulley 171, a second synchronous pulley 172, and a synchronous belt 173 connecting the two. The specific assembly relationship is as follows: the first synchronous pulley 171 is fixedly mounted on the end of the first conveyor roller 3, and correspondingly, the second synchronous pulley 172 is also fixedly mounted on the end of the second conveyor roller 4. To ensure synchronous operation of the two conveyor rollers, an annular synchronous belt 173 is precisely fitted between the first synchronous pulley 171 and the second synchronous pulley 172, achieving power transmission through toothed meshing. This transmission arrangement not only ensures the synchronicity between the conveyor rollers but also improves the stability and reliability of the entire transmission system.

[0026] As a preferred option, the bottom structure of the cutting table 1 is designed to be robust and reliable, with four bases 19 symmetrically installed at each of the four corners of the tabletop. These bases 19 are made of high-quality materials and are tightly connected to the bottom frame of the cutting table 1 by bolts, ensuring that the entire worktable remains stable and does not wobble during use. Each base 19 is precisely leveled, allowing the cutting table 1 to evenly bear the working load and effectively preventing deformation caused by uneven stress. This four-corner support design not only ensures the overall stability of the cutting table 1 but also facilitates the movement and positioning of the equipment.

[0027] As a preferred embodiment, the cutting mechanism 2 further comprises multiple precision components, mainly including: a support frame 21, a Y-axis moving component 22 for Y-axis movement, an X-axis moving component 23 for X-axis movement control, a Z-axis moving component 24 for Z-axis height adjustment, and a vibrating knife cutting machine 25 for performing the cutting task. Specifically, two sturdy support frames 21 are symmetrically fixed on both sides of the top of the cutting table 1. These two support frames 21 not only provide support but also ensure the stability of the entire mechanism. A Y-axis moving component 22 is precisely installed on the top platform of each support frame 21. This component uses a precision guide rail design to achieve smooth longitudinal movement. The X-axis moving component 23 is connected between the two Y-axis moving components 22 by a high-precision slider, allowing it to slide freely in the Y-axis direction. The X-axis moving component 23 is also equipped with a precision guide rail system, and the Z-axis moving component 24 mounted on it can achieve precise vertical lifting and lowering. Finally, at the end of the Z-axis moving component 24, a professional vibrating blade cutter 25 is installed. This cutter uses a high-frequency vibrating blade design, specifically for efficiently and accurately cutting the filter cloth 14 material. The entire cutting mechanism 2, through the coordinated operation of its various moving components, can achieve precise positioning and cutting operations in three-dimensional space.

[0028] As a preferred embodiment, the feeding component 5 further comprises four key components: a support frame 51, cylinders 52, output rods 53, and pressure blocks 54. Specifically, a horizontally arranged support frame 51 is securely installed on the top plane of the cutting table 1. This support frame is made of high-strength steel to ensure the stability of the overall structure. Multiple cylinders 52 are evenly distributed at equal intervals on the top plane of the support frame 51. The number of these cylinders 52 is precisely calculated to match the number of layers of filter cloth 14 to be cut by the production line, ensuring that each layer of filter cloth is effectively processed. Each cylinder 52 has a vertically downward-pointing output rod 53 connected to its output end. These output rods 53 are made of wear-resistant alloy material, and their bottom ends extend downwards through guide holes pre-drilled in the support frame 51. At the bottom of each output rod 53, a pressure block 54 is securely installed. These pressure blocks 54 are made of special rubber material, ensuring sufficient pressure while preventing damage to the filter cloth surface. The design of the entire feeding component 5 fully considers ease of operation and work efficiency, ensuring a smooth and orderly cutting process.

[0029] The first conveying roller, the second conveying roller, the feeding plate, the filter cloth, the motor, the Y-axis moving part, the X-axis moving part, the Z-axis moving part, the vibrating knife cutting machine, and the cylinder in this case are all existing technologies. As long as the first conveying roller, the second conveying roller, the feeding plate, the filter cloth, the motor, the Y-axis moving part, the X-axis moving part, the Z-axis moving part, the vibrating knife cutting machine, and the cylinder meet the requirements of this case, they are all acceptable.

[0030] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0031] Working Principle: All electrical components described in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. Before cutting, accurately place the cutting plate 7 into the pre-set mounting slot 6, and then use dedicated locking screws 10 to firmly fix the cutting plate 7 in the mounting slot 6, ensuring it will not shift during subsequent operations. Simultaneously, securely install the waste collection box 9 directly below the cutting trough 8 to prepare for subsequent waste collection.

[0032] When using the equipment, the operator needs to smoothly wind a sufficient amount of filter cloth 14 onto the rotating roller 13, then lay the free end of the filter cloth 14 flat on the working surface of the cutting table 1, ensuring that the first conveying roller 3 and the second conveying roller 4 can press evenly onto the surface of the filter cloth 14. The motor 16 is started by the controller provided with the equipment. When the motor 16 is running, it drives the first conveying roller 3 to rotate. Simultaneously, through the transmission action of the first synchronous pulley 171, the synchronous belt 173, and the second synchronous pulley 172, the second conveying roller 4 rotates synchronously, thereby achieving stable conveying of the filter cloth 14.

[0033] When the filter cloth 14 is conveyed to the predetermined cutting position, the controller stops the motor 16. At this time, the cutting mechanism 2 is started. Through the three-dimensional coordinated movement of the Y-axis moving part 22, X-axis moving part 23, and Z-axis moving part 24, the movement trajectory of the vibrating knife cutter 25 is precisely controlled, and the vibrating knife cutter 25 is used to precisely cut the filter cloth 14. After the cutting is completed, the motor 16 is started again to continue conveying the filter cloth 14, and the cut part is moved to a position directly above the unloading plate 7.

[0034] Then, cylinder 52 is activated, causing the output rod 53 of cylinder 52 to move downward, which drives the pressure block 54 to descend synchronously. The pressure block 54 smoothly pushes the cut filter cloth 14 into the pre-installed collection box 9, realizing the automatic collection and recycling of the cut filter cloth 14.
