Description

Technical Field

[0001] This utility model relates to the field of grinding wheel production technology, specifically to an automatic grinding wheel feeding device. Background Technology

[0002] Grinding wheels are a major type of grinding tool. They are made by mixing abrasive and binder, pressing, drying, and firing the mixture. In the current technology, grinding wheel forming involves a series of processes such as material preparation, spreading, heating, and pressing, all of which are completed on a continuous production line.

[0003] 1. Currently, when the automatic feeding device feeds materials, the abrasive passes through the feeding shell into the mold to prevent the material from scattering during feeding. However, the material will adhere to the inner wall of the feeding shell during feeding, causing material waste and resulting in poor working quality of the automatic feeding device.

[0004] 2. The automatic feeding device cannot scrape and compact the material after feeding. A separate scraping process is required to scrape the material in the mold. This means that additional scraping equipment needs to be installed in the production line, resulting in higher operating costs for the entire production line. In addition, the automatic feeding device has poor performance. Utility Model Content

[0005] To address the above problems, this utility model provides an automatic grinding wheel feeding device, which solves the aforementioned issues.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for grinding wheels, comprising a conveying device and a fixed column disposed on one side of the conveying device, wherein two electric push rods are connected to the top of the fixed column, the output end of the electric push rods is connected to a connecting block, and the top of the connecting block is connected to a support plate;

[0007] The support plate has two feeding shells inside, and the top of each feeding shell is rotatably connected to a driven gear. The inner wall of the driven gear is connected to an installation ring, and one side of the installation ring is connected to several guide scrapers.

[0008] The bottom end of the guide scraper is connected to a connecting ring. Two scraper plates are connected to one side of the connecting ring. A fixing block is connected to one side of the scraper plate. A compaction roller is connected inside the fixing block.

[0009] Preferably, a first motor is connected to the bottom of the support plate, and a rotating shaft is driven to the output end of the first motor. The outside of the rotating shaft is rotatably connected to the inside of the support plate.

[0010] Preferably, the rotating shaft is externally connected to a drive gear, which meshes with two driven gears.

[0011] Preferably, the conveying equipment is provided with a mold, and the inner bottom surface of the mold is connected to a positioning column.

[0012] Preferably, a support column is connected to the top of the conveying equipment, and a material box is connected to the top of the support column.

[0013] Preferably, the top of the material box is connected to two feed pipes, and the bottom of the material box is connected to two discharge pipes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This application uses a driven gear to drive the mounting ring and guide scraper to rotate inside the feeding shell, so that the guide scraper scrapes off the abrasive adhering to the inner wall of the feeding shell and guides the abrasive through the feeding shell into the mold. This solves the problem that the abrasive will adhere to the inner wall of the feeding shell during the feeding of the automatic feeding device, causing material waste and affecting the quality of grinding wheel production and processing. It is beneficial to improve the working quality of the automatic feeding device.

[0016] 2. This application uses a connecting ring to cooperate with a scraper plate and a compaction roller to rotate inside the mold following the guide scraper, so that the material can be scraped and compacted at the time of feeding. This solves the problem that the automatic feeding device cannot scrape and compact the material after feeding, and a separate scraping process is required for the subsequent scraping work. This is conducive to improving the practical performance of the automatic feeding device and thus reducing the working cost of the entire production line. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Please see Figures 1 to 5 An automatic feeding device for grinding wheels includes a conveying device 1 and a fixed column 4 disposed on one side of the conveying device 1. Two electric push rods 5 are connected to the top of the fixed column 4. A connecting block 6 is connected to the output end of the electric push rod 5. A support plate 7 is connected to the top of the connecting block 6. During grinding wheel production, the conveying device 1 will transport the mold to the automatic feeding device. At this time, the automatic feeding device will put the abrasive into the mold, which will facilitate the subsequent production and processing of the grinding wheel.

[0025] Of course, before the mold reaches the automatic feeding device, a matrix is ​​placed inside to support raw materials such as abrasives and binders;

[0026] When the mold reaches the automatic feeding device, the output end of the electric push rod 5 will drive the connecting block 6 and the support plate 7 to descend, so that the support plate 7 drives the two feeding shells 8 to descend, so that the lower end of the feeding shell 8 enters the interior of the mold 2. This is to prevent the lower end of the feeding shell 8 from having a height difference with the mold 2, which may cause the material to scatter during feeding. In addition, the diameter of the positioning column 3 is smaller than the diameter of the lower end of the feeding shell 8, so that the material will enter the interior of the mold 2 normally.

[0027] The support plate 7 has two feeding shells 8 inside. The top of each feeding shell 8 is rotatably connected to a driven gear 9. The inner wall of the driven gear 9 is connected to an installation ring 10. Several guide scrapers 11 are connected to one side of the installation ring 10.

[0028] A connecting ring 12 is connected to the bottom of the guide scraper 11. Two scraper plates 13 are connected to one side of the connecting ring 12. A fixing block 14 is connected to one side of the scraper plate 13. A compaction roller 15 is connected inside the fixing block 14. When feeding material, the output end of the first motor 16 will drive the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the drive gear 18 to rotate, which in turn drives the two driven gears 9 to rotate synchronously. At this time, the two driven gears 9 will rotate on the top of the corresponding feeding shell 8, so that the driven gears 9 drive the mounting ring 10 and several guide scraper 11 to rotate.

[0029] It should be further explained that the guide scraper 11 is set at an angle. When the guide scraper 11 rotates, it will scrape off the material attached to the inner wall of the feeding shell 8. The scraped material will gradually converge and flow towards the lower outlet of the feeding shell 8 along the inclined direction of the guide scraper 11, and then enter the interior of the mold 2. This avoids the material from being attached to the inner wall of the feeding shell 8, causing material waste and affecting the quality of grinding wheel production.

[0030] At the same time, when the guide scraper 11 rotates, it will drive the connecting ring 12 to rotate at the bottom of the feeding shell 8. At this time, the connecting ring 12 will drive the scraper plate 13 to rotate. The scraper plate 13 will scrape the material in the mold 2. It should be noted that because of the presence of the positioning post 3, in order to avoid scraping dead corners, the scraper plate 13 is set on the side of the positioning post 3. In this way, there will be no dead corners that cannot be scraped when the scraper plate 13 rotates.

[0031] While the scraper plate 13 rotates to scrape the material inside the mold 2, it also drives the compaction roller 15 on one side to rotate and roll, further compacting the scraped material. It is important to note that the rotation direction of the connecting ring 12 is that the scraper plate 13 rotates first, followed by the compaction roller 15. This allows for scraping and compaction during material feeding, solving the problem that the automatic feeding device cannot scrape and compact the material after feeding, requiring a separate scraping process later. This improves the practicality of the automatic feeding device and reduces the operating cost of the entire production line.

[0032] The bottom of the bearing plate 7 is connected to a first motor 16, and the output end of the first motor 16 is connected to a rotating shaft 17. The outside of the rotating shaft 17 is rotatably connected to the inside of the bearing plate 7.

[0033] The external connection of the rotating shaft 17 is a drive gear 18, which meshes with two driven gears 9. It should be further explained that the bottom of the driven gear 9 is provided with a rotating ring, and the top of the feeding shell 8 is provided with a groove. Therefore, when the driven gear 9 rotates on the top of the feeding shell 8, the rotating ring rotates in the groove on the top of the feeding shell 8.

[0034] The conveying equipment 1 is equipped with a mold 2, and the inner bottom surface of the mold 2 is connected to a positioning post 3. It should be noted that the function of the positioning post 3 is that there will be a round hole in the center of the grinding wheel, so this round hole should be reserved during the production of the grinding wheel, rather than drilling the hole after production. Therefore, the positioning post 3 needs to be set at the center of the mold 2.

[0035] The top of the conveying equipment 1 is connected to a support column 19, and the top of the support column 19 is connected to a material box 20. The material box 20 is filled with material, and the material is added into the material box 20 through the feed pipe 21, and then the feeding is automatic.

[0036] The top of the material box 20 is connected to two feed pipes 21, and the bottom of the material box 20 is connected to two discharge pipes 22. The discharge pipes 22 are equipped with valves. During automatic feeding, the valves are opened through the discharge pipes 22 to feed the material into the feeding shell 8, and then the material will enter the mold 2.

[0037] When using this utility model:

[0038] First, during the production of grinding wheels, the conveying equipment 1 will transport the mold to the automatic feeding device. At this time, the output end of the electric push rod 5 will drive the connecting block 6 and the bearing plate 7 to descend, so that the bearing plate 7 will drive the two feeding shells 8 to descend, so that the lower end of the feeding shells 8 enters the interior of the mold 2.

[0039] Secondly, the discharge pipe 22 is equipped with a valve inside. During automatic feeding, the valve is opened through the discharge pipe 22 to feed the material into the feeding shell 8, and then the material will enter the mold 2.

[0040] Then, during feeding, the output end of the first motor 16 will drive the rotating shaft 17 to rotate, which will drive the drive gear 18 to rotate, and then drive the two driven gears 9 to rotate synchronously. At this time, the two driven gears 9 will rotate at the top of the corresponding feeding shell 8, which will drive the mounting ring 10 and several guide scrapers 11 to rotate and scrape off the material attached to the inner wall of the feeding shell 8. The scraped material will gradually converge and flow towards the lower outlet of the feeding shell 8 along the inclined direction of the guide scrapers 11, and then enter the interior of the mold 2.

[0041] Finally, when the guide scraper 11 rotates, it will drive the connecting ring 12 to rotate at the bottom of the feeding shell 8. At this time, the connecting ring 12 will drive the scraper plate 13 to rotate. The scraper plate 13 will scrape the material in the mold 2. When the scraper plate 13 rotates and scrapes the material inside the mold 2, it will also drive the compaction roller 15 on one side to rotate and roll, and further compact the scraped material.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
