Description

Technical Field

[0001] The present invention relates to the technical field of abrasive tool processing, and particularly relates to a feeding device for abrasive tool forming. Background Art

[0002] Abrasive tools are tools used for grinding, lapping, and polishing. Most abrasive tools are artificial abrasive tools made of abrasives plus binders, and there are also natural abrasive tools directly processed from natural ore rocks. The proportion of mixed abrasives during abrasive tool forming has an important impact on the properties of abrasive tools such as hardness, wear resistance, cutting efficiency, self-sharpening, and toughness. For example, by increasing the proportion of high-hardness abrasives such as corundum and silicon carbide in the abrasive tool, the overall hardness of the abrasive tool will be significantly improved, enhancing the ability of the abrasive tool to resist the intrusion of external forces, making it not easily worn by stones during the cutting process and maintaining good cutting performance.

[0003] After retrieval, for example, a feeding device for abrasive tool forming with the publication number CN115999691A drives the belt feeding plate to move through the operation of the screen. During the movement of the belt feeding plate, the materials in the pouring area are brought onto the screen. The screen sieves the materials, and the sieved materials enter the feeding area through the leakage opening. The output end of the vibration motor drives the vibration shaft to rotate, and then drives the vibration block to rotate, causing the screen to vibrate and improving the sieving efficiency, so that the feeding device for abrasive tool forming has a sieving effect.

[0004] However, during the actual feeding process of the above device, after experiencing bumps and being entered by loose abrasives into the feeding area, vibration dispersion makes it highly random and unable to evenly fall into the feeding pipe to be conveyed by the conveying blades. There will be a large difference in the mass of abrasives conveyed in each section, reducing the stability of the feeding process, and resulting in uneven proportions after falling into the pouring area. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] As Figure 1 - Figure 5 In an embodiment of the present invention, a feeding device for abrasive tool forming is provided, which includes a material conveyor 2 driven by a driving mechanism 1. The output shaft of the driving mechanism 1 is in transmission connection with one of the transmission shafts of the material conveyor 2. It is characterized in that a feeding hopper 3 is arranged on one side of the material conveyor 2. The bottom of the feeding hopper 3 is connected to a discharge box 4. A plurality of support columns are arranged at the bottom of the discharge box 4. A quantitative material transfer device 6 is rotatably installed in the inner cavity of the discharge box 4 through a shaft rod 5, and the quantitative material transfer device 6 is in transmission connection with the driving mechanism 1.

[0031] Specifically, the driving mechanism 1 can be a servo motor, which is in transmission connection with the transmission shaft of the material conveyor 2 and the quantitative material transfer device 6 through belt drive, chain drive, or coupling, etc.; it can also be a pneumatic motor with compressed air as the power source. In some abrasive tool production environments with explosion-proof requirements, such as workshops with flammable and explosive dust, the pneumatic motor is a more suitable driving mechanism 1. It can be connected to the gas source through an air pipeline, and its rotation speed and output power can be controlled by adjusting the intake air volume and air pressure. Although the output power of the pneumatic motor is relatively small, for some small abrasive tool feeding devices, it is sufficient to meet the requirements of driving the material conveyor 2 and the quantitative material transfer device 6.

[0032] Referring to Figure 2 and Figure 3 , the inner cavities of the feeding hopper 3 and the discharge box 4 are connected. A T-shaped plate 7 for blocking the blanking opening is slidably connected to the top opening of the discharge box 4. A pull rod 8 is fixedly installed on the outer wall of the T-shaped plate 7, and the pull rod 8 is used to adjust the size of the blanking opening between the feeding hopper 3 and the discharge box 4.

[0033] Specifically, pour a single type of required abrasive (such as diamond, corundum or quartz sand) into the feed hopper 3, start the driving mechanism 1, and the driving mechanism 1 drives the rotation of a transmission shaft of the material conveyor 2 in a transmission connection manner, so that the material conveyor 2 starts to work. According to the actual abrasive ratio requirement, pull the pull rod 8 outward to drive the T-shaped plate 7 to move from the top of the discharge box 4. The abrasive falls into the discharge box 4 under the action of its own gravity, and the movement of the T-shaped plate 7 changes the size of the material falling opening between the feed hopper 3 and the discharge box 4. At this time, the rotation speed of the driving mechanism 1 remains unchanged. By changing the size of the material falling opening between the feed hopper 3 and the discharge box 4, the amount of abrasive falling onto the quantitative material transfer device 6 in a certain time is changed. The quantitative material transfer device 6 then batches the abrasive onto the material conveyor 2, avoiding large differences in the quality of the abrasive conveyed by each section of the material conveyor 2 and improving the stability of the feeding process.

[0034] Refer to Figure 2 On the outer wall of the discharge box 4, an adjusting block 11 is fixedly installed. A number of adjusting grooves 12 are linearly formed on the wall body of the adjusting block 11. The bottom end of the pull rod 8 is rotatably installed with a locking rod 13 through a rotating shaft, and the locking rod 13 is movably clamped in any one of the adjusting grooves 12.

[0035] Specifically, pull the pull rod 8 outward to drive the T-shaped plate 7 to move on the top of the discharge box 4, and the locking rod 13 moves synchronously in the direction away from the discharge box 4. Then move the locking rod 13 to a suitable adjusting groove 12 and rotate the locking rod 13 so that the locking rod 13 is movably clamped in any one of the adjusting grooves 12 to fix the overall horizontal position of the T-shaped plate 7.

[0036] Refer to Figure 4 Refer to

[0037] Refer to Figure 2 and Figure 5, a driving wheel 9 is fixedly sleeved on the output shaft of the driving mechanism 1. One end of the shaft rod 5 extends to the outside of the discharging box 4, and a first driven wheel 10 is fixedly sleeved on this end of the shaft rod 5. The driving wheel 9 and the first driven wheel 10 are connected by a sleeved belt for transmission; a stirring rod 16 is movably installed through the inner cavity of the feeding hopper 3, and the stirring rod 16 is in transmission connection with the driving mechanism 1. A plurality of support rods are integrally formed on the outer wall of the stirring rod 16; one end of the stirring rod 16 extends to the outside of the feeding hopper 3, and a second driven wheel 17 is fixedly sleeved on this end of the stirring rod 16. The second driven wheel 17 and the first driven wheel 10 are connected by a sleeved belt for transmission.

[0038] Specifically, when the driving mechanism 1 drives the material conveyor 2 to work, the driving wheel 9 drives the first driven wheel 10 to rotate synchronously. The first driven wheel 10 drives the second driven wheel 17 to rotate through the belt, so that the stirring rod 16 continuously stirs the poured abrasive, avoiding blocking the bottom opening of the feeding hopper 3; after the abrasive in the feeding hopper 3 passes through the top opening of the discharging box 4, the abrasive falls into each storage cavity 63 in batches. The first driven wheel 10 rotates to drive the metering material transfer device 6 to rotate, so that the sand and gravel are metered and fall into the discharging port 14, and then fall from the discharging port 14 onto the material conveyor 2, and are fed to the receiving port of the designated equipment through the material conveyor 2.

[0039] Refer to Figure 3 , a support plate 18 is arranged on the outer wall of the feeding hopper 3, a blower 19 is placed on the top of the support plate 18, the air inlet end of the blower 19 is connected with a dust collection hood through a pipeline, and a filter screen 20 is detachably installed at the opening of the dust collection hood.

[0040] Specifically, during the process that the stirring rod 16 continuously stirs the abrasive, the dust attached to the surface of the abrasive floats up. The blower 19 is turned on, and the dust is sucked through the dust collection hood, so that the dust or impurities adhere to the surface of the filter screen 20, reducing the impurities attached to the surface of the abrasive.

[0041] In summary, the working principle of the present invention is:

[0042] Pour the required single type of abrasive into the feed hopper 3 for stirring. During the stirring process, the dust adhering to the surface of the abrasive will float. At this time, turn on the blower 19, and the blower 19 sucks the dust through the dust collection hood. The dust or impurities adhere to the surface of the detachable filter screen 20, reducing the impurities on the surface of the abrasive. Start the drive mechanism 1 to drive the material conveyor 2, the shaft rod 5, and the stirring rod 16 to start working. According to the actual abrasive ratio requirements, pull out the pull rod 8 outward. The pull rod 8 drives the T-shaped plate 7 to move on the top of the discharge box 4. When it moves to the appropriate position, rotate the locking rod 13 so that it snaps into the appropriate adjustment groove 12 on the wall of the adjustment block 11, thereby fixing the horizontal position of the T-shaped plate 7. The abrasive falls into the discharge box 4 under the action of its own gravity and is batch-fed into each storage cavity 63 of the quantitative transfer device 6. The abrasive is batch-fed quantitatively onto the material conveyor 2 through the discharge port 14. The abrasive falls from the discharge port 14 onto the material conveyor 2. The baffle 15 on the conveyor belt of the material conveyor 2 helps to better carry the abrasive. Finally, the abrasive is fed to the receiving port of the designated equipment. The whole process controls the amount of abrasive falling into the quantitative transfer device 6 by changing the size of the falling material opening, avoiding excessive differences in the mass of the abrasive conveyed by each section of the material conveyor 2 and improving the stability of the feeding process.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
