Description

Technical Field

[0001] The utility model relates to the technical field of filter base cloth processing, in particular to a high-density filter base cloth tension adjustment device. Background Art

[0002] Traditional high-density filter fabric tension adjustment devices typically employ simple mechanical structures for tension adjustment. These devices typically utilize a single adjustment component or a series of discrete adjustment units to tighten or loosen the fabric. In common designs, these adjustment components operate independently, requiring manual adjustment of each adjustment point to control fabric tension. While this method achieves a certain degree of tension adjustment, it is complex and offers limited effectiveness. Furthermore, the clamping components in traditional devices, typically consisting of simple clips or rollers, cannot guarantee uniform grip on the filter fabric, leading to slippage and uneven tension.

[0003] Traditional devices lack a flexible linkage structure, and multiple adjustment components cannot be synchronized, resulting in the need to adjust them one by one. This is not only time-consuming and labor-intensive, but can also easily affect the overall tension distribution of the base fabric due to uneven adjustment. In particular, when precise adjustment of base fabrics of different specifications is required, traditional equipment is difficult to adapt effectively, and tension deviation and inadequate adjustment are prone to occur. In addition, the clamping structure of traditional devices is simply designed and cannot provide a stable fixation during the stretching process of the filter cloth. During the tension adjustment process, the filter cloth is prone to slippage or position displacement, resulting in unsatisfactory tension adjustment effect. Especially for high-density filter base fabrics, uneven tension can seriously affect the filtration effect and service life of the product. In addition, the traditional clamping structure lacks the ability to adapt to different tension requirements, requiring frequent adjustments during use, which increases the complexity of operation.

[0004] In view of this, research and improvement are carried out on the existing problems, and a high-density filter base cloth tension adjustment device is provided to solve the current problems. The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Utility Model Content

[0006] A high-density filter base cloth tension adjustment device comprises: a fixed disk, a tension guide assembly, a filter cloth clamping assembly and a drive rod, wherein the tension guide assembly comprises a plurality of deformation forks and linkage ears, adjacent deformation forks are movably connected by the linkage ears, a plurality of filter cloth clamping assemblies are evenly distributed in the circumferential direction, and the two ends of the drive rod are movably connected to one end of the filter cloth clamping assembly and the surface of the fixed disk respectively; the filter cloth clamping assembly comprises a clamping seat and an operating rod and a pressure head rod rotatably mounted on the surface of the clamping seat, a sliding pin is rotatably mounted on the inner side of the operating rod, the surface of the pressure head rod is provided with a pressure ridge, the sliding pin slides and abuts against the surface of the pressure ridge, and one end of the pressure head rod is provided with a pressure head block arranged opposite to the clamping seat surface. By adopting the above technical solution and through this structural design, the device can flexibly perform radial adjustment through the linkage structure of the tension guide assembly, so that the filter cloth clamping assembly can evenly adjust the tension of the base cloth along the circumferential direction, effectively adapt to different tension requirements, and improve the accuracy and uniformity of adjustment.

[0007] In a preferred embodiment, the present invention can be further configured such that the deformable fork includes two mutually rotatably connected connecting rods, and the two connecting rods are connected in an X-shape. By adopting the above technical solution and the design of the X-shaped connecting rod, the deformable fork can flexibly adapt to tension changes in different directions during radial adjustment, thereby enhancing the stability and ease of operation of the overall device.

[0008] In a preferred embodiment, the present invention can be further configured such that the plurality of deformable forks are divided into a plurality of groups, each group of deformable forks forming a ring and movably mounted on the surface of a fixed disk. The groups of deformable forks are arranged in a coaxial ring shape and sequentially connected by linkage ears, and the filter cloth clamping assembly is arranged on the surface of the deformable forks. By adopting this technical solution, by mounting the deformable fork group as a ring structure on the surface of the fixed disk, the device can better achieve uniform distribution and adjustment of tension in the coaxial direction, further improving adjustment accuracy.

[0009] In a preferred embodiment, the present invention can be further configured such that the linkage ears are provided with four pins for connecting to the ends of the deformable fork connecting rods, and the ends of the connecting rods are pivotally connected to the linkage ears via the pins. By adopting this technical solution, the pinned connection design allows adjacent deformable forks to rotate flexibly while maintaining a secure connection, enhancing the linkage and stability of the overall structure.

[0010] In a preferred embodiment, the present invention can be further configured such that the bottom end of the operating rod is pivotally connected to the surface of the clamping seat, the sliding pin is located in the middle of the operating rod, and the pressure ridge surface has a smooth arc structure, with the pressure ridge gradually decreasing in inclination as it moves away from the connection point between the pressure rod and the clamping seat. By adopting this technical solution, the smooth arc structure of the pressure ridge surface ensures that the operating rod can slide smoothly on the sliding pin surface during tension adjustment, preventing the base fabric from getting stuck and being damaged during adjustment.

[0011] In a preferred embodiment, the present invention can be further configured such that the drive rod is either an electric push rod or a hydraulic rod, and is used to drive the radial movement of the filter cloth clamping assembly. By employing this technical solution, using an electric push rod or a hydraulic rod as the drive rod, the radial movement of the filter cloth clamping assembly can be more precisely controlled, making the device more efficient and accurate in tension adjustment, and adapting to different tension requirements.

[0012] The beneficial effects achieved by the utility model are:

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] The following is combined with Figure 1-Figure 5 The present invention describes a high-density filter fabric tension adjustment device provided in some embodiments.

[0025] Example 1

[0026] The utility model provides a high-density filter base cloth tension adjustment device, comprising: a fixed plate 100, a tension guide assembly 200, a filter cloth clamping assembly 300, and a drive rod 400. The tension guide assembly 200 includes a plurality of deformable forks 210 and linkage ears 220, with adjacent deformable forks 210 movably connected via the linkage ears 220. The plurality of filter cloth clamping assemblies 300 are evenly distributed in a circumferential direction. The two ends of the drive rod 400 are respectively movably connected to one end of the filter cloth clamping assembly 300 and the surface of the fixed plate 100.

[0027] The filter cloth clamping assembly 300 includes a clamping base 310, an operating rod 320 rotatably mounted on the surface of the clamping base 310, and a pressure rod 330. A sliding pin 321 is rotatably mounted on the inner side of the operating rod 320. The surface of the pressure rod 330 is provided with a pressure ridge 332, and the sliding pin 321 slides and abuts against the surface of the pressure ridge 332. One end of the pressure rod 330 is provided with a pressure block 331 arranged opposite the surface of the clamping base 310. This structure allows the device to flexibly adjust the base cloth tension according to actual needs while ensuring that the base cloth does not slip or shift during the adjustment process.

[0028] To further enhance performance, the deforming forks 210 are configured as two rotatably connected connecting rods in an X-shaped arrangement. This allows for a wider adjustment range during radial movement, enhancing the tension guidance capabilities of the base fabric. The multiple deforming forks 210 can be divided into several groups. Each group of deforming forks 210 is combined to form a ring and movably mounted on the surface of the fixed disk 100. The groups are arranged in a coaxial ring shape and connected in sequence by linkage ears 220. The filter cloth clamping assembly 300 is arranged on the surface of the deforming forks 210, allowing the device to achieve simultaneous tension adjustment in multiple directions, maintaining uniform tension on the base fabric.

[0029] The driving rod 400 is an electric push rod, which is used to drive the radial movement of the filter cloth clamping assembly 300, making the tension adjustment process more automated and efficient, and reducing the complexity and instability of manual operation.

[0030] Example 2

[0031] This embodiment further optimizes Example 1 by improving the design of the linkage lugs 220 and deformable fork 210, allowing for more flexible tension adjustment. The linkage lugs 220 are equipped with four pins for connecting to the ends of the connecting rods of the deformable fork 210. The ends of the connecting rods are rotatably connected to the linkage lugs 220 via the pins. This connection not only improves the linkage between the deformable forks 210 but also ensures the stability of each deformable fork 210 during radial adjustment.

[0032] Furthermore, the bottom end of the operating rod 320 is pivotally connected to the surface of the clamping base 310. The surface of the pressure ridge 332 is designed as a smooth arc structure, and its inclination gradually decreases away from the connection point between the pressure rod 330 and the clamping base 310. This design ensures smoother sliding of the operating rod 320, reduces adjustment problems caused by friction, and further improves the service life of the device.

[0033] This utility model also features a drive rod 400, which acts as a hydraulic rod. Compared to electric push rods, this hydraulic rod offers greater thrust, making it suitable for applications requiring significant adjustments. When in operation, the drive rod 400 precisely drives the filter cloth clamping assembly 300 in radial motion, ensuring stable and reliable tension adjustment under varying operating conditions.

[0034] Through the optimization of the above embodiments, the utility model can more accurately and reliably adjust the tension of the high-density filter base cloth, is suitable for the production and processing scenarios of various high-density base cloths, improves the convenience of operation and the level of automation, and can ensure the stability and uniformity of the base cloth during the adjustment process, effectively improving production efficiency.

[0035] The working principle and use process of this utility model:

[0036] Place the outer periphery of the high-density filter fabric onto the clamping seats 310 of each filter fabric clamping assembly 300, ensuring the fabric is flat and free of folds. Using the operating lever 320, press the pressing rod 330 down onto the fabric to ensure it is securely clamped. Adjust the position of the operating lever 320 so that the pressing ridge 332 slides into contact with the sliding pin 321, further locking the fabric.

[0037] Activating the drive rod 400 causes the device to begin radially pulling the base fabric. The electric push rod or hydraulic lever of the drive rod 400 drives the filter cloth clamping assembly 300 in radial motion. The combined design of the deformable fork 210 and the linkage lug 220 ensures the linkage of the entire device, allowing the tension guide assembly 200 to uniformly and synchronously adjust the tension of the base fabric, avoiding uneven localized force.

[0038] During the fabric transmission process, the operator can monitor the tension in real time through the control panel and adjust the parameters of the drive rod 400 when necessary to accurately control the stretching degree of the fabric. After the tension adjustment is completed, the tension is maintained until the fabric is stabilized.
