Description

Technical Field

[0002] Abrasives are sharp, hard materials used to grind the surfaces of softer materials. Abrasives are divided into two categories according to their manufacturing methods: natural abrasives and artificial abrasives. They are classified into two categories according to their hardness: superhard abrasives and ordinary abrasives. The range of abrasives is very wide, from softer household detergents and gem abrasives to the hardest material, diamond. Abrasives are essential materials for manufacturing every precision product. Many natural abrasives have been replaced by artificial abrasives. In various equipment that use abrasives, an abrasive supply device is required to hold the abrasive and conveniently provide the abrasive to other downstream devices.

[0003] At present, most abrasive supply devices are cylindrical or box structures. When abrasive supply is needed, the abrasive in the cylinder or box enters the conveying pipe and mixes with the pressurized liquid flowing along the conveying pipe, and then is conveyed together to the downstream device. However, since the abrasive itself is a granular structure, the friction between the abrasive particles is large when the abrasive accumulates inside the cylinder or box structure, resulting in a large flow resistance of the abrasive, which makes it easy for the abrasive to get stuck inside the cylinder or box structure, making it difficult for the abrasive to enter the conveying pipe smoothly and continuously, thereby affecting the supply effect of the abrasive. In addition, the abrasive is prone to agglomeration when stored in the cylinder or box structure for a long time, and the agglomerated abrasive is even more difficult to enter the conveying pipe smoothly.

[0029] The present invention will be further explained below with reference to specific embodiments.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 This embodiment provides an abrasive supply device, including an abrasive storage cylinder 10, a feed pipe 20, a drive assembly 30 and a stirring and bulking assembly 40. The abrasive storage cylinder 10 is fixedly arranged on the upper part of the feed pipe 20 and is connected to the feed pipe 20. One end of the feed pipe 20 is connected to an external pressurizing device (not shown in the figure), and the other end is connected to an abrasive receiving mechanism (not shown in the figure). One end of the stirring and bulking assembly 40 extends to the top of the abrasive storage cylinder 10, and the other end extends from the top of the abrasive storage cylinder 10 to the inside of the abrasive storage cylinder 10. The drive assembly 30 is installed on the top of the abrasive storage cylinder 10, and is used to drive the stirring and bulking assembly 40 to move up and down and rotate to stir and disperse the abrasive inside the abrasive storage cylinder 10.

[0031] When the abrasive is supplied, the abrasive inside the abrasive storage tube 10 falls into the feed pipe 20, and at the same time, the liquid is transported to the feed pipe 20 by using an external booster device. When the liquid enters the feed pipe 20, it mixes with the abrasive and then enters the abrasive receiving mechanism together to realize the supply of the abrasive. In the above process, the driving component 30 drives the stirring bulk component 40 to move up and down and rotate, thereby performing dual stirring of the abrasive inside the abrasive storage tube 10 in the vertical and horizontal directions, thereby preventing the abrasive from getting stuck inside the abrasive storage tube 10, and at the same time breaking up the agglomerated abrasive, so that the abrasive can enter the feed pipe 20 smoothly and stably, thereby improving the supply effect of the abrasive.

[0032] See also Figure 1 、 Figure 3 as well as Figure 4 In one embodiment, the bulk material stirring assembly 40 includes a top plate 401, a support tube 402 and a stirring rod 409, one end of the support tube 402 extends to the top of the abrasive storage cylinder 10 and is fixedly connected to the top plate 401, and the other end extends from the top of the abrasive storage cylinder 10 to the inside of the abrasive storage cylinder 10, the support tube 402 is distributed axially along the abrasive storage cylinder 10, and the stirring rod 409 is provided in a plurality of groups, and a plurality of the stirring rods 409 are fixedly arranged on the outer wall of the support tube 402 located inside the abrasive storage cylinder 10, and the driving The dynamic component 30 includes a drive motor 302, a drive shaft 303, a rotating wheel 304 and a shift rod 305. The drive motor 302 is installed above the abrasive storage tube 10, the drive shaft 303 is arranged at the output end of the drive motor 302, the rotating wheel 304 is fixedly arranged outside the drive shaft 303, and the rotating wheel 304 is located on the side of the support tube body 402. The shift rod 305 is provided in several groups, and several of the shift rods 305 are fixedly arranged on the circumferential side wall of the rotating wheel 304. Several of the shift rods 305 are distributed in a ring-shaped manner on the circumferential side wall of the rotating wheel 304.

[0033] When the abrasive inside the abrasive storage cylinder 10 falls into the feed pipe 20 and mixes with the liquid, the drive shaft 303 is driven to rotate by the drive motor 302, thereby driving the rotating wheel 304 to rotate. When the rotating wheel 304 rotates, it drives the plurality of levers 305 to move in a circular motion. When the plurality of levers 305 move in a circular motion, they act on the bottom edge of the top plate 401 in sequence. When a certain group of levers 305 acts on the bottom edge of the top plate 401, it pushes the top plate 401 so that the support tube 402 moves upward compared to the abrasive storage cylinder 10, thereby driving the plurality of stirring rods 409 to move upward. When the group of levers 305 pushes the top plate 401 to a predetermined height, When the abrasive storage tube 10 is opened, the shift rod 305 is separated from the top plate 401, and then the top plate 401, the support tube 402 and the stirring rods 409 move downward relative to the abrasive storage tube 10 under the action of gravity, until the next group of shift rods 305 acts on the bottom edge of the top plate 401 again, thereby driving the top plate 401, the support tube 402 and the stirring rods 409 to move up again. This reciprocating cycle can realize the up and down movement of the stirring rods 409 along the inside of the abrasive storage tube 10, and then vertically stir the abrasive inside the abrasive storage tube 10 to avoid the abrasive from getting stuck and clumping, thereby improving the supply effect of the abrasive.

[0034] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 In one embodiment, the driving assembly 30 also includes a bracket plate 301, which is fixedly arranged on the upper part of the abrasive storage tube 10, and the driving motor 302 is fixedly installed on the side wall of the bracket plate 301, and the driving shaft 303 passes through the bracket plate 301 and rotates with the bracket plate 301.

[0035] By setting the bracket plate 301, rotation support can be provided for the drive shaft 303, and then rotation support can be provided for the rotating wheel 304 and several levers 305, so that the rotating wheel 304 can rotate smoothly, and then drive the several levers 305 to move smoothly in a circular motion, so that the top plate 401, the support tube body 402 and several stirring rods 409 can move up and down smoothly.

[0036] See also Figure 5 In one embodiment, a turntable 405 is fixedly provided on the outside of the support tube body 402 located above the abrasive storage cylinder 10. The turntable 405 is located below the top plate 401. A plurality of paddles 406 are fixedly provided on the upper edge of the turntable 405 and are arranged obliquely with respect to the diameter of the turntable 405. The plurality of paddles 406 are distributed in a ring-shaped manner on the upper part of the turntable 405.

[0037] When a certain group of levers 305 separates from the top plate 401, causing the top plate 401, the support tube body 402 and the plurality of stirring rods 409 to move downward and reset, a subsequent group of levers 305 rotates to the top of the turntable 405 and acts on the side wall of a certain group of paddles 406. At this time, since the paddles 406 are arranged obliquely with respect to the diameter of the turntable 405, the levers 305 act on the side wall of the paddles 406 to push the turntable 405 to rotate, thereby driving the support tube body 402, the top plate 401 and the plurality of stirring rods 409 to rotate as a whole by a predetermined angle. When the levers 305 separate from the paddles 406, a group of levers 305 acts on the bottom edge of the top plate 401 again, thereby pushing the top plate 401, the support tube body 402 and the plurality of stirring rods 409 to rotate as a whole. The plurality of stirring rods 409 move upwards again, and the lever 305 separates from the top plate 401, so that the top plate 401, the support tube body 402 and the plurality of stirring rods 409 move downwards and reset again. Then, a group of levers 305 acts on the side walls of a subsequent group of paddles 406, thereby pushing the turntable 405, the support tube body 402, the top plate 401 and the plurality of stirring rods 409 to rotate a predetermined angle again. This reciprocating cycle can make the movement state of the plurality of stirring rods 409 inside the abrasive storage tube 10 move up and down - rotate - move up and down - rotate..., so that the abrasive obtains a dual stirring effect in the vertical and horizontal directions, thereby increasing the stirring range of the abrasive and improving the conveying and supply effect of the abrasive.

[0038] See also Figure 5 as well as Figure 6 In one embodiment, a rotating support seat 407 is movably provided on the outer wall of the support tube body 402, and the rotating support seat 407 is rotatably installed on the top wall of the abrasive storage cylinder 10. The bottom of the turntable 405 and the rotating support seat 407 are also connected by an elastic member 408, and the elastic member 408 is used to provide elastic tension to the turntable 405.

[0039] When a certain group of levers 305 acts on the bottom edge of the top plate 401 and drives the top plate 401, the support tube 402 and the plurality of stirring rods 409 to move upward, the support tube 402 moves upward compared to the rotating support seat 407, thereby driving the turntable 405 to move upward compared to the rotating support seat 407. When the turntable 405 moves upward, the elastic member 408 is stretched; when the group of levers 305 is separated from the top plate 401, the elastic member 408 pulls the turntable 405 and drives the support tube 402 to move quickly. When the turntable 405, the support tube 402, the top plate 401 and the stirring rods 409 move downward quickly, thereby realizing the rapid reset of the top plate 401, the support tube 402 and the stirring rods 409; when a certain group of shift rods 305 acts on the side wall of a certain group of shift pieces 406 and thereby drives the turntable 405, the support tube 402, the top plate 401 and the stirring rods 409 to rotate, the turntable 405 drives the rotating support seat 407 to rotate relative to the top wall of the abrasive storage tube 10 through the elastic member 408.

[0040] See also Figure 5 In one embodiment, a plurality of guide rods 404 are fixedly provided on the upper portion of the rotating support seat 407 , and the upper ends of the guide rods 404 pass through the turntable 405 and movably cooperate with the turntable 405 .

[0041] When a certain group of levers 305 acts on the bottom edge of the top plate 401 and thereby drives the support tube body 402 and a number of stirring rods 409 to move upward, the turntable 405 can move upward compared to the guide rod 404. When a certain group of levers 305 acts on the side wall of a certain group of paddles 406 and thereby drives the turntable 405, the support tube body 402, the top plate 401 and a number of stirring rods 409 to rotate, the turntable 405 drives the rotating support seat 407 to rotate adaptively and synchronously through the several guide rods 404. At this time, the elastic member 408 is not subjected to torsion, thereby avoiding the elastic member 408 being subjected to torsion and causing its life to be reduced.

[0042] In one embodiment, the elastic member 408 may be a spring or a metal spring, which is not limited here.

[0043] When the lever 305 is separated from the top plate 401, the top plate 401, the support tube 402 and the plurality of stirring rods 409 are reset downwards by the help of their own weight and the pulling of the elastic member 408, and the downward movement of the plurality of stirring rods 409 occurs inside the abrasive. Therefore, the plurality of stirring rods 409 are easily subjected to greater resistance from the abrasive when moving downwards, resulting in the top plate 401, the turntable 405 and the plurality of paddles 406 possibly not being able to smoothly move downwards to the initial position, making it impossible for the subsequent lever 305 to continue to push up against the top plate 401, and at the same time making it impossible for the subsequent lever 305 to smoothly push sideways against the paddle 406, resulting in an unsatisfactory effect of the subsequent mixing and bulking of the abrasive. For this reason, please refer to Figure 5 as well as Figure 7In one embodiment, the stirring rod 409 includes a rod body 4091 and a flexible belt 4093. The rod body 4091 is provided with an air delivery channel 4092 connected to the inner cavity of the support tube body 402. The side wall of the rod body 4091 is provided with a slot connected to the air delivery channel 4092 along the length direction. The flexible belt 4093 is encapsulated inside the slot. A piston assembly 50 is further provided inside the support tube body 402. When the support tube body 402 and the plurality of stirring rods 409 move upward, the piston assembly 50 is used to pressurize air into the air delivery channel 4092 to drive the flexible belt 4093 to expand outward, thereby increasing the volume of the rod body 4091. The upward movement of the rod body 4091 drives more abrasives to move upward to improve the stirring and dispersing effect of the abrasives. When the support tube body 402 and the several stirring rods 409 move downward, the piston assembly 50 is used to extract the air inside the air supply channel 4092 to drive the flexible belt 4093 to contract, so that the volume of the rod body 4091 is reduced, thereby reducing the downward resistance of the rod body 4091 along the inside of the abrasive, thereby ensuring that the support tube body 402, the turntable 405, the top plate 401 and the several paddles 406 can be smoothly moved down and reset, so that the several stirring rods 409 can subsequently move up and down and rotate smoothly inside the abrasive storage tube 10, thereby continuously stirring and dispersing the abrasive.

[0044] See also Figure 5 In one embodiment, a vertically distributed slide groove 403 is opened on the side wall of the support tube body 402, and the piston assembly 50 includes a piston rod 501 and a connecting rod 502. The piston rod 501 is movably arranged inside the support tube body 402, and one end of the connecting rod 502 is fixedly connected to the piston rod 501, and the other end extends from the slide groove 403 to the outside of the support tube body 402 and is fixedly connected to the guide rod 404.

[0045] When a certain group of levers 305 acts on the bottom edge of the top plate 401 and drives the support tube body 402 and the plurality of stirring rods 409 to move upward, the piston rod 501 is confined inside the support tube body 402 by the connecting rod 502 and the guide rod 404, so that the support tube body 402 moves upward compared to the piston rod 501. At this time, the connecting rod 502 slides down along the inside of the slide groove 403. When the support tube body 402 moves upward compared to the piston rod 501, the piston rod 501 pressurizes the air inside the support tube body 402 into the air delivery channel 4092 to drive the flexible belt 4093 outward. The flexible belt 4093 contracts to reduce the downward resistance of the rod 4091 along the inside of the abrasive, so that the top plate 401, the support tube 402, the turntable 405 and the plurality of paddles 406 can be smoothly reset.

[0046] In one embodiment, the flexible belt 4093 can be a flexible rubber belt or a flexible silicone belt, which is not limited here.

[0047] See also Figure 1 In one embodiment, a feeding port 101 is provided on the top of the abrasive storage tube 10 , and abrasive can be added to the abrasive storage tube 10 through the setting of the feeding port 101 .

[0048] In one embodiment, a discharge valve (not shown in the figure) is provided at the bottom inner side of the abrasive storage cylinder 10. When abrasive supply is not required, the discharge valve is in a closed state, thereby preventing the abrasive inside the abrasive storage cylinder 10 from entering the feed pipe 20. When abrasive supply is required, the discharge valve can be opened to allow the abrasive inside the abrasive storage cylinder 10 to enter the feed pipe 20 and mix with the flowing liquid.

[0049] The working principle of the present invention is as follows:

[0050] When the abrasive is supplied, the abrasive in the abrasive storage cylinder 10 enters the feed pipe 20, and the external booster device is turned on at the same time. The external booster device transports the liquid into the feed pipe 20. After the liquid enters the feed pipe 20, it mixes with the abrasive and enters the abrasive receiving mechanism. During the above process, the drive motor 302 can be started, and the drive motor 302 drives the wheel 304 to rotate through the drive shaft 303, thereby driving the plurality of levers 305 to move in a circle. The plurality of levers 305 act on the bottom edge of the top plate 401 in turn. The edge, in conjunction with the pulling effect of the elastic member 408 on the turntable 405, causes the top plate 401, the support tube body 402 and the plurality of stirring rods 409 to move up and down, thereby realizing vertical stirring of the abrasive. When the plurality of levers 305 act on the gap between the top plate 401, the plurality of levers 305 can also act on the side walls of the plurality of paddles 406 in turn, thereby pushing the support tube body 402, the top plate 401 and the plurality of stirring rods 409 to rotate, thereby stirring the abrasive horizontally. The abrasive is fully dispersed after vertical and horizontal stirring. When the support tube 402 moves upward, the piston rod 501 pressurizes the air inside the support tube 402 to the air delivery channel 4092 inside the rod 4091, thereby driving the flexible belt 4093 on the side wall of the rod 4091 to expand outward, so that the volume of the rod 4091 increases. When the volume of the upwardly moving rod 4091 increases, more abrasive can be driven upward, thereby improving the dispersion effect of the abrasive. When 402 moves downward, the piston rod 501 draws the air in the air delivery channel 4092 inside the rod body 4091 into the interior of the support tube body 402, causing the flexible belt 4093 to shrink, thereby reducing the volume of the rod body 4091, and further reducing the resistance of the rod body 4091 from the abrasive when it moves downward, so that the support tube body 402, the top plate 401, the turntable 405 and the plurality of paddles 406 can be smoothly moved downward and reset, thereby allowing the subsequent vertical and horizontal mixing of the abrasive to proceed smoothly.

[0051] In the embodiment of the present invention, when the abrasive is supplied, the abrasive located inside the abrasive storage cylinder 10 falls into the feed pipe 20, and at the same time, the liquid is transported to the feed pipe 20 by using an external pressurizing device. When the liquid enters the feed pipe 20, it is mixed with the abrasive and then enters the abrasive receiving mechanism together to realize the supply of the abrasive. In the above process, the driving component 30 drives the stirring and bulking component 40 to move up and down and rotate, thereby performing dual stirring of the abrasive inside the abrasive storage cylinder 10 in the vertical and horizontal directions, thereby preventing the abrasive from getting stuck inside the abrasive storage cylinder 10, and at the same time, breaking up the agglomerated abrasive, so that the abrasive can enter the feed pipe 20 smoothly and stably, thereby improving the supply effect of the abrasive. Compared with the prior art, during the abrasive supply process, the abrasive inside the abrasive storage cylinder 10 can be subjected to dual stirring and dispersion treatment in the vertical and horizontal directions, thereby preventing the abrasive from getting stuck and ensuring smooth and continuous supply of the abrasive.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
