Description

Technical Field

[0001] This utility model relates to the technical field of abrasive feeding devices for grinding wheels, and specifically to an abrasive feeding device for grinding wheels. Background Technology

[0002] Abrasives are tools used for grinding, lapping, and polishing. They are mainly divided into artificial abrasives and natural abrasives. Artificial abrasives are made of abrasives and binders, while natural abrasives are made directly from natural minerals. Artificial abrasives, such as the grinding wheels used in angle grinders, are made by mixing abrasives, binders (such as resins and ceramics), and other additives in a specific ratio, then placing the mixture in a mold, pouring it into the abrasive, letting the mixture stand until it stabilizes, and then pressing the mixture into shape using a pressing device to form a grinding wheel.

[0003] Chinese utility model patent CN222201382U discloses an abrasive feeding device for grinding wheels, including a "material hopper". A feeding pipe is fixedly connected to the lower end of the hopper. A screen is installed in the upper part of the feeding pipe. A top plate is provided on the upper side of the hopper. A connecting shaft is fixedly connected to the middle of the upper surface of the top plate. A horizontal plate rotatably connected to the connecting shaft is sleeved on the connecting shaft. A second pulley is fixedly connected to the upper end of the connecting shaft. The second pulley is connected to a first pulley via a transmission belt. The first pulley is mounted on a motor output shaft. An elongated opening is provided on the upper surface of the horizontal plate away from the connecting shaft. The motor output shaft passes through the elongated opening. A cloth is installed on the lower surface of the horizontal plate along the length of the horizontal plate. The device features an electric push rod, the movable end of which is fixedly connected to a motor. Multiple agitator rods are mounted on the lower surface of the top plate. The device first starts the motor under no-load conditions and controls the electric push rod to move the motor, causing it to rotate via a transmission belt, which in turn rotates the agitator rods to disperse the abrasive. However, after the abrasive stabilizes in the hopper, it adheres to the agitator rods. When the motor starts under no-load conditions, it moves, pulling the motor and transmission belt together, causing the transmission belt to rotate. During this process, due to the adhesion between the abrasive and the agitator rods, although the motor will drive the transmission belt when it comes into contact with it, slippage occurs between the transmission belt and the pulley, preventing the connecting shaft from rotating. Utility Model Content

[0004] The purpose of this invention is to provide an abrasive feeding device for grinding wheels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an abrasive feeding device for grinding wheels, comprising a hopper, wherein an adjusting component is provided inside the hopper, a movable support is movably connected to the outer wall of the adjusting component, and a stirring component is rotatably connected to the inner wall of the movable support;

[0006] A mounting bracket is fixedly installed on the top surface of the hopper, and a sieve plate is provided inside the outlet at the bottom end of the hopper;

[0007] The adjustment assembly includes a screw and a worm gear. There are two screws, and a worm gear is fixedly connected to the bottom end of each screw. The two ends of the worm gear are respectively provided with worm teeth. The end of the worm gear is installed and connected to the output end of a servo motor that is fixedly installed on the outer wall of the hopper.

[0008] A vertical rod is fixedly connected to the bottom surface of the movable support, and a rotating hole is opened through the interior of the vertical rod;

[0009] The stirring assembly includes a rotating rod and a transmission chain. A rotating wheel is fixedly connected to the top of the rotating rod. The rotating wheel is connected to a rotating wheel via the transmission chain. The top of the rotating wheel is connected to the output end of a servo motor that is fixedly installed on the top surface of the movable support. A disc is fixedly connected to the bottom of the rotating rod. Multiple stirring rods are fixedly connected to the bottom surface of the disc in a circumferential array.

[0010] The beneficial effects of this utility model are as follows: This device, by setting up an adjustment component, a moving bracket, and a stirring component, uses a servo motor to drive a turbine to rotate within the mounting bracket. A worm gear synchronously drives screws on both sides to rotate, thereby causing the moving bracket to move up and down along the screw direction. The moving bracket further drives the stirring component to move up and down together, thus moving multiple stirring rods at the bottom of the stirring component upwards from the abrasive in the hopper. After the abrasive stabilizes, a second servo motor, via a transmission chain, drives the shaft and the bottom stirring rods to rotate under no-load. Once the stirring rods begin to rotate, the adjustment component moves the moving bracket along with the stirring component downwards. The high-speed rotating stirring rods disperse the abrasive in the hopper sequentially from the top surface. The adjustment component then removes the stirring component from the abrasive. This structure effectively avoids the problem of slippage caused by the motor contacting the transmission chain during no-load rotation.

[0011] To achieve the effect of synchronously driving the screws on both sides to rotate:

[0012] The configuration is further defined as follows: the turbines at the bottom ends of the two screws are respectively engaged with the worm gears at both ends of the worm.

[0013] By adopting the above technical solution, while the worm rotates, the spiral teeth at both ends mesh with the turbine, thereby synchronously driving the screws on both sides to rotate.

[0014] To achieve the effect of vertical adjustment and movement of the movable stand:

[0015] The configuration is further defined as follows: the two screws are located on both sides of the mounting bracket, and the outer walls of the two screws are threadedly connected to the inner walls of both ends of the movable bracket, and the outer wall of the vertical rod is slidably connected to the inner wall of the mounting bracket.

[0016] By adopting the above technical solution, the movable bracket is moved up and down along the screw direction within the mounting bracket by the screws on both sides.

[0017] To achieve the effect of stirring and dispersing by rotating the stirring rod:

[0018] The configuration is further defined as follows: the outer wall of the rotating rod is rotatably connected to the inner wall of the rotating hole inside the vertical rod, and the disc is located at the bottom end of the vertical rod.

[0019] By adopting the above technical solution, the second servo motor drives the rotating rod to rotate in the rotating hole of the vertical rod through the transmission chain, and then drives the multiple stirring rods at the bottom to rotate together through the disc, so as to achieve the effect of stirring and dispersing by rotating the stirring rods.

The two ends of the worm gear 22 are respectively provided with worm teeth 221. The end of the worm gear 22 is installed and connected to the output end of a servo motor 222 fixedly installed on the outer wall of the hopper 1.

[0033] A vertical rod 31 is fixedly connected to the bottom surface of the movable support 3, and a rotating hole 32 is opened through the inside of the vertical rod 31;

[0034] The stirring assembly 4 includes a rotating rod 41 and a transmission chain 43. A rotating wheel 42 is fixedly connected to the top of the rotating rod 41. The rotating wheel 42 is connected to the rotating wheel 44 via the transmission chain 43. The top of the rotating wheel 44 is connected to the output end of the servo motor 45 fixedly mounted on the top surface of the movable bracket 3. A disc 46 is fixedly connected to the bottom of the rotating rod 41. Multiple stirring rods 47 are fixedly connected to the bottom surface of the disc 46 in a circumferential array.

[0035] In this embodiment, as Figure 1 and Figure 4 As shown, the turbines 211 at the bottom of the two screws 21 are respectively engaged with the worm gears 221 at both ends of the worm 22.

[0036] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, two screws 21 are located on both sides of the mounting bracket 11, and the outer walls of the two screws 21 are threadedly connected to the inner walls of both ends of the movable bracket 3, and the outer wall of the vertical rod 31 is slidably connected to the inner wall of the mounting bracket 11.

[0037] In this embodiment, as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the outer wall of the rotating rod 41 is rotatably connected to the inner wall of the rotating hole 32 inside the vertical rod 31, and the disc 46 is located at the bottom end of the vertical rod 31.

[0038] The computer software involved in the hardware carriers such as servo motor one and servo motor two in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0039] Therefore, the "servo motor one" and "servo motor two" mentioned in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0040] The working process of this abrasive feeding device is as follows:

[0041] First, the uniformly mixed abrasive is added into the hopper 1. After the abrasive settles and stabilizes, the servo motor 245 is started to drive the rotating wheel 244 to rotate. Through the transmission chain 43, the rotating wheel 142 is driven to rotate synchronously. The rotating wheel 142 drives the rotating rod 41 to rotate in the rotating hole 32 of the vertical rod 31, thereby enabling the disc 46 and the stirring rod 47 to run without load. Then, the servo motor 222 is started to drive the worm gear 22 to rotate in the mounting bracket 11. The worm gear 221 at both ends of the worm gear 22 meshes with the worm wheel 211 of the screw 21 on both sides, driving the screw 21 to rotate synchronously, so that the moving bracket 3 can be raised and lowered smoothly along the axial direction of the screw 21.

[0042] During this process, the stirring component 4 disperses the abrasive material in the hopper 1 layer by layer from top to bottom. The dispersed abrasive material is screened and discharged through the bottom screen plate 12 of the hopper 1. By removing the stirring component 4 from the abrasive material and running it under no-load, the problem of slippage caused by the motor contacting the transmission chain 43 during no-load rotation is effectively avoided.

[0043] Servo motor one and servo motor two can adopt the existing known model 1PM4105-2LF86-1CS1, which are all well-known existing technologies. The above model can be used, but it is not limited to this.
