Description

Technical Field

[0001] The utility model relates to a sand box trolley cleaning mechanism, which relates to the technical field of cleaning trolleys for casting. Background Art

[0002] Sand mold transportation is a very important process in the production line of the foundry industry. It involves the automatic transportation of the sand box on the trolley. During the processing and transportation of the sand mold, some residual sand or other solids will fall on the trolley, which will cause the surface of the trolley to be uneven. When the trolley transports the sand mold again, it will affect the stability and flatness of the sand mold on the trolley. For example, a push-type offline cleaning mechanism with a Chinese patent announcement number of CN208131960U mainly pushes the sand mold to the collection table by pushing the offline plate. During the pushing process, the metal brush at the bottom of the offline plate cleans the residual sand in the exhaust groove, and then the scraper scrapes the residual sand that has been cleaned out. When the pushing down line plate completes the pushing action of the sand mold, the pushing down line plate returns to the starting position under the action of the pushing down line cylinder. During the return process, the metal brush and scraper once again clean the remaining sand in the exhaust groove. However, the existing cleaning structure simply scrapes the trolley surface with the metal brush and scraper when passing the upper side of the trolley, and the metal brush and scraper are usually fixed and cannot adapt to the accumulation on the upper surface of the trolley. This may cause incomplete cleaning or poor cleaning effect in some areas. Forcibly scraping objects will only make it easier to damage the scraper and affect its service life. The processing and use of the molding sand are not ideal. Therefore, it is necessary to design a sand box trolley cleaning mechanism. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a sand box trolley cleaning mechanism to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: a sand box trolley cleaning mechanism, comprising a support frame, a slide, and a driving device for driving the slide to slide linearly on the support frame, wherein the bottom of the slide is sequentially installed with a rubber scraper, an alloy horizontal scraper, a grooved alloy scraper and a brush from front to back, wherein the grooved alloy scraper is elastically rotatably connected to the slide, and the bottom of the grooved alloy scraper is lower than the horizontal line of the rubber scraper and the brush, and the bottom of the alloy horizontal scraper is higher than the horizontal line of the rubber scraper and the brush.

[0005] Based on the above technical solution, a rotating frame assembly is provided on the lower side of the slide, and the grooved alloy scraper is rotatably mounted on the lower side of the rotating frame assembly.

[0006] Based on the above technical solution, the rotating frame assembly includes multiple longitudinal frame plates locked and installed at the bottom of the slide, and a rotating shaft is rotatably installed in the middle of each longitudinal frame plate. Multiple transverse frame plates corresponding to the lower side of the longitudinal frame plate are fixedly installed on the rotating shaft, and a reset spring is connected between the longitudinal frame plate and the transverse frame plate, and the grooved alloy scraper is installed on one side of the transverse frame plate.

[0007] Based on the above technical solution, a plurality of notches are provided at the bottom of the grooved alloy scraper.

[0008] Based on the above technical solution, a plurality of negative pressure through holes are opened on the surface of the rotating shaft, the interior of the rotating shaft is hollow and connected to each negative pressure through hole, and a dust suction pipe is installed at one end of the rotating shaft, and the dust suction pipe is connected to an external vacuum cleaner.

[0009] Based on the above technical solution, the longitudinal frame plate and the transverse frame plate are both U-shaped.

[0010] Based on the above technical solution, the brush is a soft brush.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The utility model is provided with a rubber scraper, an alloy horizontal scraper, a grooved alloy scraper and a brush in sequence from front to back at the bottom of the slide. The cooperation of the multi-stage scraper and the brush can effectively clean the molding sand on the platform, realizing a gradual cleaning process from more to less. Compared with the existing technology, it can ensure that the molding sand on the surface of the trolley is more comprehensive and effective.

[0013] In addition, the rubber scraper is made of rubber, which is used to initially scrape off large particles of molding sand and some softer residues attached to the trolley, thereby avoiding damage to the molding sand and the surface of the trolley. The alloy horizontal scraper follows the rubber scraper and is used to further clean the residual molding sand. It is suitable for handling some more stubborn sand particles. The trough-shaped alloy scraper rotates and tilts and sticks to the upper surface of the trolley when passing through the trolley, and uses the elastic force of the reset spring of the rotating frame assembly to scrape the molding sand. This can reduce the rigid contact between them, and the last brush is used to clean the fine sand and dust that are difficult to clean with the scraper. During this period, since there are multiple negative pressure through holes distributed on the surface of the rotating shaft and connected to the hollow part, the hollow part is connected to the aspirator through the dust suction pipe. Therefore, the raised dust can be absorbed simultaneously while scraping the sand, thereby improving the cleaning and use effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] Please refer to this Figure 1-Figure 3 The present invention provides a technical solution of a sand box trolley cleaning mechanism: it includes a support frame 1, a slide 2, and a driving device 3 for driving the slide 2 to slide linearly on the support frame 1. The driving device 3 is in the prior art, and is pushed by a cylinder or a hydraulic cylinder to push the slide 2, so that the slide 2 is rolled along the guide rail on the support frame 1 by the rail wheel. Therefore, the driving device 3 is not further described here. The bottom of the slide 2 is sequentially installed with a rubber scraper 4, an alloy horizontal scraper 5, a grooved alloy scraper 6 and a brush 7 from front to back, so that they are arranged side by side in sequence. Through the cooperation of this multi-stage scraper and brush 7, the molding sand on the trolley can be effectively cleaned, realizing a gradual cleaning process from more to less. The grooved alloy scraper 6 is elastically rotatably connected to the slide 2, and the bottom of the grooved alloy scraper 6 is lower than the horizontal line of the rubber scraper 4 and the brush 7, and the bottom of the alloy horizontal scraper 5 is higher than the horizontal line of the rubber scraper 4 and the brush 7, and is adjacently arranged on the upper side of the trolley for scraping sand.

[0021] A rotating frame assembly 8 is provided on the lower side of the slide 2, and the grooved alloy scraper 6 is rotatably installed on the lower side of the rotating frame assembly 8. The rotating frame assembly 8 includes a plurality of longitudinal frame plates 81 locked and mounted on the bottom of the slide 2, and a rotating shaft 9 is rotatably installed in the middle of each longitudinal frame plate 81. A plurality of transverse frame plates 82 corresponding to the lower side of the longitudinal frame plates 81 are fixedly mounted on the rotating shaft 9, so that the transverse frame plates 82 can rotate on the longitudinal frame plates 81 through the rotating shaft 9, and a reset spring 83 is connected between the longitudinal frame plates 81 and the transverse frame plates 82, and the transverse frame plates 82 are reset and supported by the reset spring 83, and the grooved alloy scraper 6 is installed and can move synchronously with one side of the transverse frame plate 82, wherein the grooved A plurality of slots 61 are provided at the bottom of the alloy scraper 6. The slots 61 are designed mainly for cleaning the larger residual molding sand particles, while the finer molding sand and dust particles are cleaned by the subsequent brush 7, which can give full play to the cleaning effect of the brush 7. A plurality of negative pressure through holes 91 are provided on the surface of the rotating shaft 9. The interior of the rotating shaft 9 is hollow and is connected to each negative pressure through hole 91. A dust suction pipe 92 is installed at one end of the rotating shaft 9. The dust suction pipe 92 is externally connected to a vacuum cleaner, so that it has the effect of dust suction and dust removal while hanging and sweeping the molding sand. The longitudinal frame plate 81 and the transverse frame plate 82 are both U-shaped and staggered with each other. The brush 7 is a soft brush, which is also convenient for entering the gap of the trolley for cleaning.

[0022] During use, the driving device 3 is used to push the slide 2 to move toward the upper side of the trolley. The heights of the rubber scraper 4, the grooved alloy scraper 6 and the brush 7 are all lower than the lifting level. Only the height of the alloy horizontal scraper 5 is adjacent to the upper side of the trolley. In this way, when passing the upper side of the trolley, the rubber scraper 4, the grooved alloy scraper 6 and the brush 7 can fully contact the upper side of the trolley. The first rubber scraper 4 can scrape off large particles of molding sand and some softer residues attached to the trolley, and the rubber material has a certain softness. When scraping away most of the molding sand, it can reduce damage to the molding sand and the surface of the trolley. The alloy horizontal scraper 5 follows the rubber scraper 4 and is used to further clean the residual molding sand. Since the alloy horizontal scraper 5 has a high hardness, it is suitable for handling some more stubborn sand particles. The first two passes can scrape off most of the molding sand dust, and pass through the third grooved alloy scraper 6 and the last brush. 7 is used to quickly remove the residue on the surface of the molding sand. When the grooved alloy scraper 6 passes the upper side of the trolley, it is blocked and rotates backward under the action of the rotating shaft 9. The end is tilted and contacts the trolley, and the horizontal frame plate 82 rotates and tilts synchronously. The grooved alloy scraper 6 uses the return spring 83 between the longitudinal frame plate 81 and the horizontal frame plate 82 to elastically support the upper side of the trolley and scrape the molding sand, which can reduce the rigid contact between them. During this period, the vacuum cleaner externally connected to the dust suction pipe 92 works, so that the negative pressure through hole 91 of the rotating shaft 9 generates negative pressure, thereby recovering and cleaning the dust and fine sand while hanging and sweeping, and the brush can penetrate into the tiny gaps on the surface of the trolley, providing a more thorough cleaning effect. After the scrapers and brushes 7 at all levels complete the scraping of the molding sand, they return to their positions, and the grooved alloy scraper 6 returns to its original position under the elastic force of the return spring 83, ready for the next cleaning.
