Description

Technical Field

[0001] This utility model relates to the field of multi-layer filter press technology, specifically a filter cloth positioning device for ultrasonic welding of filter cloth in multi-layer filter press. Background Technology

[0002] A multi-layer filter press is a solid-liquid separation device composed of multiple layers of filter plates, filter frames, and filter cloths. The filter cloth positioning device for ultrasonic welding of filter cloths in a multi-layer filter press is a key auxiliary device used to accurately fix and align the multiple layers of filter cloths during ultrasonic welding. Its core function is to ensure that each layer of the filter cloth is completely overlapped and without displacement during welding, thereby ensuring the sealing and strength of the weld joint.

[0003] Current filter cloth positioning devices utilize various mechanical structures, such as positioning pins, baffles, and positioning grooves, to limit the edges or specific parts of the filter cloth, preventing it from moving or shifting during welding and ensuring accurate relative positioning. However, when the filter cloth surface is uneven or wrinkled, the positioning device cannot handle the wrinkles, resulting in the wrinkled filter cloth affecting the processing quality. Utility Model Content

[0004] The purpose of this utility model is to provide a filter cloth positioning device for ultrasonic welding of filter cloth in multi-layer filter presses. It has the advantage of smoothing out the wrinkles on the filter cloth while positioning it, so as to avoid affecting the processing quality. It solves the problem that the positioning device cannot handle the wrinkled filter cloth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter cloth positioning device for ultrasonic welding of filter cloth in a multi-layer filter press, comprising a worktable, screw sleeves, and fixing rods. A fixing frame is fixedly installed on the front side of the worktable, a hydraulic cylinder is fixedly installed on the top of the fixing frame, a fixing block is fixedly installed on the bottom of the hydraulic cylinder, and lead screws are movably installed on both sides of the fixing block. Two screw sleeves are engaged with two lead screws, and fixing sleeves are fixedly installed on the bottom of each of the two screw sleeves. Insertion holes are opened on the bottom of each of the two fixing sleeves. The tops of the two fixing rods are inserted into the interiors of the two fixing sleeves through the two insertion holes. Springs are fixedly installed inside the two fixing sleeves. Retainers are fixedly installed on the bottom of each of the two fixing rods, and pressure rollers are movably installed on the inner sides of each of the two retainers.

[0006] Preferably, a slider is fixedly installed on the front side of the fixing block, and a sliding groove is opened on the rear side of the fixing frame, with the slider and the sliding groove being slidably connected.

[0007] Preferably, a handwheel is fixedly installed at the opposite ends of the two lead screws, and the two lead screws are fixedly connected at opposite ends.

[0008] Preferably, the outer threads of the two lead screws are distributed in opposite directions.

[0009] Preferably, both of the threaded sleeves are provided with positioning holes, and positioning rods are fixedly installed on both sides of the fixing block, with the two positioning rods passing through the two positioning holes.

[0010] Preferably, a baffle is installed on the top of each of the two fixing rods, and the outer diameter of the two baffles is larger than the inner diameter of the two insertion holes.

[0011] Preferably, a support frame is fixedly installed at the bottom of the workbench, and the bottom of the support frame has fixing holes arranged in a rectangular array.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes threaded sleeves and pressure rollers. A hydraulic cylinder lowers a fixed block, which in turn lowers the threaded sleeves via two lead screws. This causes the pressure rollers inside the two retainers below the threaded sleeves to contact the filter cloth on the top of the worktable. Springs inside the two fixed sleeves are compressed to provide cushioning. By rotating one of the lead screws using a handwheel, both lead screws rotate synchronously, causing the two threaded sleeves to move in opposite directions on the two rotating lead screws. The two threaded sleeves drive the two retainers to move in opposite directions. The pressure rollers inside the two retainers apply pressure to the filter cloth while simultaneously tightening it during the movement, making the filter cloth surface smooth. This achieves the effect of smoothing out wrinkles on the filter cloth while positioning it, thus avoiding affecting the processing quality. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a filter cloth positioning device for ultrasonic welding of filter cloth in a multi-layer filter press, including a worktable 3, a screw sleeve 6, and a fixing rod 16. A fixing frame 11 is fixedly installed on the front side of the worktable 3, a hydraulic cylinder 10 is fixedly installed on the top of the fixing frame 11, a fixing block 4 is fixedly installed on the bottom of the hydraulic cylinder 10, a slider 13 is fixedly installed on the front side of the fixing block 4, and a sliding groove 12 is opened on the rear side of the fixing frame 11. The slider 13 and the sliding groove 12 are slidably connected. The hydraulic cylinder 10 is connected to an external hydraulic source. When the hydraulic cylinder 10 drives the fixing block 4 to rise and fall, the fixing block... 4. The slider 13 slides within the groove 12 of the fixed frame 11 to prevent the fixed block 4 from shaking. Two lead screws 8 are movably mounted on both sides of the fixed block 4. Handwheels 7 are fixedly mounted on opposite ends of the two lead screws 8. The two lead screws 8 are fixedly connected at opposite ends. The two handwheels 7 can be used to rotate the two lead screws 8. When one lead screw 8 rotates, the other lead screw 8 rotates synchronously. Two threaded sleeves 6 engage with the two lead screws 8. The outer threads of the two lead screws 8 are distributed in opposite directions. When the two lead screws 8 rotate, the two threaded sleeves 6 can engage with the two rotating lead screws. The two threaded sleeves 6 are moved in opposite or opposite directions. Each threaded sleeve 6 has a positioning hole 17. Positioning rods 9 are fixedly installed on both sides of the fixing block 4. The two positioning rods 9 pass through the two positioning holes 17. When the two threaded sleeves 6 move, they move on the two positioning rods 9 through the two positioning holes 17 to prevent them from shaking. A fixing sleeve 14 is fixedly installed at the bottom of each threaded sleeve 6. Each fixing sleeve 14 has an insertion hole 19 at its bottom. The tops of the two fixing rods 16 are inserted into the two fixing sleeves 14 through the two insertion holes 19. Each of the two baffles 18 is installed on the top. The outer diameter of the two baffles 18 is larger than the inner diameter of the two insertion holes 19. The two baffles 18 prevent the two fixing rods 16 from slipping out of the two insertion holes 19. Springs 20 are fixedly installed inside the two fixing sleeves 14.
