Description
Technical Field
[0001] This utility model relates to the field of spinning preparation equipment, and in particular to a flat sand tool for spinning filter components. Background Technology
[0002] Spinning filter components are key parts in spinning production. They are mainly used to filter impurity particles in the spinning melt or solution to prevent clogging of the spinneret orifices and affecting the quality of the filaments. Their structural design and filtration accuracy play a crucial role in the stability of the spinning process and the performance of the final product. Sand leveling tools are mainly used to level the metal sand, ensuring its uniform distribution and providing a good foundation for subsequent metal processing or casting processes.
[0003] A sand leveling tool for spinning filter modules is a specially designed device primarily used to level the sand layer within the module. It mechanically levels the sand layer, providing a smooth working surface. As the tool moves across the sand surface, its own weight or additional pressure presses down protruding sand particles, ensuring a uniform sand layer height. It also scrapes away excess sand particles, redistributing them to thinner areas, thus achieving a level sand layer. This ensures that the spinning solution passes through the sand layer evenly during filtration, preventing localized excessively fast or slow flow rates. Some sand leveling tools can also moderately compact the sand layer, enhancing its overall stability and preventing easy damage to the sand layer structure during spinning filtration, thereby maintaining good filtration performance.
[0004] In the existing technology, some flat sanding tools used for spinning filter components are time-consuming and prone to uneven sorting due to the use of hard cards by the assemblers during the assembly process. This can lead to leakage and uneven pressure when the components are installed on the machine, resulting in repeated component replacements and fuzzy fibers during spinning. Ultimately, this increases production costs and causes product quality problems. Therefore, a flat sanding tool for spinning filter components is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a flat sand tool for spinning filter components, which aims to improve the problems of repeated component replacement and fuzzing in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sand leveling tool for a spinning filter assembly includes a housing. A fixed plate is detachably connected to the top of the housing. A rocker arm is rotatably connected inside the fixed plate. A connecting ring is fixedly connected to the bottom of the rocker arm. Two support plates are fixedly connected to the outside of the connecting ring. A connecting column is fixedly connected to the top of the support plates. A sliding groove is formed inside the connecting column. A sliding column is slidably connected inside the sliding groove. A spring is sleeved on the outside of the sliding column. A sleeve is sleeved on the outside of the connecting column. Sand leveling scrapers are fixedly connected to the bottom of the two sliding columns. Stirring blocks are fixedly connected to the left and right sides of the bottom of the sand leveling scrapers.
[0008] As a further description of the above technical solution:
[0009] A fixing ring is fixedly connected to the top of the fixing plate, and two exhaust ports are opened inside the fixing plate;
[0010] As a further description of the above technical solution:
[0011] A crank handle is fixedly connected to the top of the rocker arm, and the bottom of the sleeve is fixedly connected to the top of the flat sand scraper.
[0012] As a further description of the above technical solution:
[0013] The two ends of the flat sand scraper are in contact with the inner wall of the housing, and the outside of the sleeve is slidably connected to the inside of the housing;
[0014] As a further description of the above technical solution:
[0015] The top of the spring is fixedly connected to the bottom of the chute, and the bottom of the spring is fixedly connected to the top of the flat sand scraper.
[0016] As a further description of the above technical solution:
[0017] The flat sand scraper is rectangular in shape, and the mixing block is arc-shaped.
[0018] This utility model has the following beneficial effects:
[0019] In this invention, by cranking the handle, the connecting ring rotates, which in turn rotates the support plate. The connecting column and sliding column then rotate the flat sand scraper for tidying. Simultaneously, the stirring block fully agitates the metal sand, facilitating its tidying. The sliding column slides within its groove and automatically resets due to the elasticity of the spring, preventing damage to the flat sand assembly. The spring's elasticity also compacts the metal sand using the flat sand scraper, effectively enhancing the density and stability of the metal sand layer. This allows it to better withstand the pressure during the filtration process in the spinning filter assembly, reducing voids between metal sand particles, improving impurity retention, and ultimately enhancing the filtration accuracy of the spinning filter assembly.

[0025] 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.
[0026] Reference Figures 1 to 3The present invention provides an embodiment of a flat sand tool for a spinning filter assembly, comprising a housing 1, which is a place for holding metal sand. A fixed plate 2 is detachably connected to the top of the housing 1. After the metal sand is cleaned, the flat sand assembly is removed by removing the fixed plate 2. A rocker arm 3 is rotatably connected inside the fixed plate 2. The rocker arm 3 drives the flat sand assembly to rotate. A connecting ring 4 is fixedly connected to the bottom of the rocker arm 3. The connecting ring 4 ensures that it will not loosen or break during long-term use. Two support plates 5 are fixedly connected to the outside of the connecting ring 4. The support plates 5 provide support for the flat sand assembly such as the flat sand scraper 11 at the bottom.
[0027] A connecting column 6 is fixedly connected to the top of the support plate 5. A sliding groove 7 is provided inside the connecting column 6 to ensure that the sliding column 8 can slide smoothly in it. The sliding column 8 is slidably connected inside the sliding groove 7. A spring 9 is sleeved on the outside of the sliding column 8. The spring 9 can provide sufficient elasticity to realize the up and down movement and reset function of the flat sand scraper 11. A sleeve 10 is sleeved on the outside of the connecting column 6 to protect the spring 9 and the sliding column 8. The flat sand scraper 11 is fixedly connected to the bottom of the two sliding columns 8. The flat sand scraper 11 sorts the metal sand. Stirring blocks 12 are fixedly connected to the left and right sides of the bottom of the flat sand scraper 11. The stirring blocks 12 make the metal sand fully mixed and evenly distributed in the sand box to prevent the metal sand from clumping or local accumulation.
[0028] Reference Figure 1 and Figure 3 The top of the fixed plate 2 is fixedly connected to a fixed ring 13, which allows the rocker arm 3 to rotate freely at its center position. At the same time, the fixed ring 13 can also limit the rocker arm 3. The fixed plate 2 has two exhaust ports 14 inside, which can keep the air pressure in the sand box relatively stable, making the scraping and stirring process of metal sand more uniform and efficient. The top of the rocker arm 3 is fixedly connected to a handle 15, which makes it easy for the operator to operate. The bottom of the sleeve 10 is fixedly connected to the top of the flat sand scraper 11, ensuring that the two move synchronously during the working process. The two ends of the flat sand scraper 11 are in contact with the inner wall of the shell 1, preventing metal sand from getting stuck at both ends of the scraper and causing damage to the flat sand scraper 11. At the same time, when the flat sand scraper 11 rotates, it can cover the inner area of the box to the maximum extent.
[0029] The sleeve 10 is externally slidably connected to the inside of the housing 1, so that the sleeve 10 can maintain linear movement during the up and down sliding process without deviation or jamming, thereby ensuring the smooth movement of the flat sand scraper 11 in the vertical direction. The top of the spring 9 is fixedly connected to the bottom of the slide groove 7, and the bottom of the spring 9 is fixedly connected to the top of the flat sand scraper 11. The spring 9 plays a key role in elastic support in this structure, providing fixation and stability for the spring 9. The flat sand scraper 11 is rectangular in appearance and has rounded corners to prevent the sharp corners from scratching the inner wall of the sand box or causing abnormal accumulation and splashing of metal sand during the rotation of the flat sand scraper 11. The stirring block 12 is arc-shaped, which allows it to better cut into the metal sand and push the metal sand to move during rotation.
[0030] Working principle: When it is necessary to sort the metal sand in the box, the outer part of the fixed plate 2 is locked to the top of the shell 1. By shaking the handle 15, the connecting ring 4 is rotated. The connecting ring 4 drives the support plates 5 on both sides to rotate. The connecting column 6 and the sliding column 8 drive the flat sand scraper 11 to rotate, sorting the metal sand. At the same time, the stirring block 12 can fully stir the metal sand, making it more evenly distributed in the sand box, which is convenient for sorting the metal sand. When the metal sand inside clumps and the flat sand scraper 11 cannot sort it, it can slide in its groove 7 through the sliding column 8. At the same time, the elasticity of the spring 9 will automatically reset it to prevent damage to the flat sand assembly. The elasticity of the spring 9 will also drive the flat sand scraper 11 to compact the metal sand.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
