Description

Technical Field

[0001] This utility model relates to the field of grinding wheel processing technology, and in particular to a stirring device for grinding wheel processing. Background Technology

[0002] During the production of grinding wheels, raw materials (abrasives, binders, additives, etc.) need to be uniformly mixed, dispersed, and preheated to ensure the particle distribution, hardness, and lifespan of the grinding wheel. A stirring device is typically used to agitate the materials in a container, with the motor driving the stirring rod to rotate. To facilitate the loading and unloading of containers and the adjustment of the stirring position, lifting mechanisms such as cylinder lifting or screw lifting can be used to raise and lower the stirring device. However, because the motor is positioned above the stirring rod, it rises and falls along with the stirring device during lifting, increasing the load on the lifting mechanism and causing the overall center of gravity to be too high, affecting the stability of the equipment. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems of existing stirring devices when they are raised and lowered.

[0004] To achieve the objectives of this utility model, the following technical solution is adopted: A stirring device for grinding wheels includes a base, a stirring assembly, and a lifting assembly. The stirring assembly is mounted on the base and includes a drive mechanism, a rotating sleeve, a rotating rod, a transmission mechanism, and a stirring rod. The drive mechanism is mounted on the base, and the rotating sleeve is connected to the drive mechanism. The rotating rod is inserted from top to bottom into the hollow cavity of the rotating sleeve and rotates synchronously with the rotating sleeve. The transmission mechanism is located at the top of the rotating rod, and the stirring rod is connected to the transmission mechanism and moves synchronously with the rotating rod. The lifting assembly drives the transmission mechanism to rise and fall, and when the transmission mechanism rises and falls, the stirring rod and the rotating rod rise and fall synchronously.

[0005] In some embodiments, there are at least two stirring rods, and several stirring rods are arranged in parallel and connected to the rotating rods respectively through a transmission mechanism.

[0006] In some embodiments, the transmission mechanism is mounted on a mounting base, and the lifting assembly includes a driver and a lifting rod connected to the driver. The driver is mounted on a base, and one end of the lifting rod is connected to the driver, while the other end is connected to the mounting base.

[0007] In some embodiments, the stirring rod, rotating rod, and lifting rod are arranged in parallel.

[0008] In some embodiments, the rotating sleeve and the rotating rod are connected by a keyway.

[0009] In some embodiments, the transmission mechanism includes a transmission gear, each stirring rod is connected to the transmission gear, and the rotating rod is provided with a drive gear that meshes with the transmission gear.

[0010] In some embodiments, a container is provided on the base, and a stirrer is provided at the bottom of the stirring rod. The stirrer corresponds to the container. The stirrer includes a sleeve, a fixed plate, and a movable part. The sleeve is detachably connected to the stirring rod. The fixed plate is disposed around the sleeve. The movable part is provided with a strip groove. The movable part is connected to the fixed plate through the strip groove and the fixing assembly.

[0011] In some embodiments, the fixing plate has a positioning groove with a through hole, the movable part is disposed in the positioning groove, and the fixing assembly includes a fixing member that passes through the strip groove and the through hole.

[0012] The stirring device for grinding wheel processing provided by this utility model has the following advantages: This invention employs a drive mechanism mounted on a base, which is separate from the transmission mechanism of the stirring rod. This eliminates the need for the drive mechanism to move with the stirring rod as it rises and falls, reducing the load on the lifting assembly. Simultaneously, it enables multiple stirring rods to stir simultaneously, improving stirring efficiency. Furthermore, the stirrer can be adjusted for different containers to achieve better stirring results. Attached Figure Description

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] In this embodiment, "several" and "more than" refer to two or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0027] <Example 1> like Figures 1 to 5 As shown in the figure, this embodiment provides a stirring device for grinding wheels, including a base 1, a stirring assembly 2, and a lifting assembly 3. The stirring assembly 2 is mounted on the base 1 and is used to stir materials. The stirring assembly 2 includes a drive mechanism 21, a rotating sleeve 22, a rotating rod 23, a transmission mechanism 24, and a stirring rod 25. The drive mechanism 21 is mounted on the base 1 and is used to provide driving force, and is supported by the base 1. The rotating sleeve 22 is connected to the drive mechanism 21, enabling the drive mechanism 21 to drive the rotating sleeve 22 to rotate. Specifically, the drive mechanism 21 includes a motor 211, which can rotate the rotating sleeve 22 through a known belt drive or gear drive. The rotating rod 23 is inserted from top to bottom into the hollow cavity 221 of the rotating sleeve 22. When the rotating sleeve 22 rotates, the rotating rod 23 rotates synchronously with the rotating sleeve 22. Specifically, the rotating sleeve 22 and the rotating rod 23 are connected by a keyway. That is, several axial grooves 222 are provided on the rotating sleeve 22, and corresponding axial protrusions are provided on the surface of the rotating rod 23. The protrusions cooperate with the grooves 222. Of course, other existing assembly structures can also be used, as long as the rotating rod 23 and the rotating sleeve 22 can move relative to each other axially and rotate synchronously in the rotational direction. The transmission mechanism 24 is located at the top of the rotating rod 23. The stirring rod 25 is connected to the transmission mechanism 24 and moves synchronously with the rotating rod 23. When the rotating rod 23 rotates, the transmission mechanism 24 drives the stirring rod 25 to rotate, thereby performing stirring. The transmission mechanism 24 is located at the top of the stirring rod 25 and the rotating rod 23, and is separate from the drive mechanism 21, which can distribute the weight. The lifting assembly 3 drives the transmission mechanism 24 to rise and fall. When the transmission mechanism 24 rises and falls, the stirring rod 25 and the rotating rod 23 rise and fall synchronously. In this embodiment, the mixing device for grinding wheels is used by raising the mixing rod 25 to a high position via the lifting assembly 3. The material to be mixed is then placed in the container 10, which is placed on the base 1 and corresponds to the position of the mixing rod 25. The lifting assembly 3 lowers the mixing rod 25 into the container 10, and the drive mechanism 21 provides power to rotate the mixing rod 25 for mixing. Since the lifting assembly 3 does not need to drive the drive mechanism 21 to raise or lower, the power requirement of the lifting assembly 3 is reduced.

[0028] Furthermore, there are at least two stirring rods 25, and several stirring rods 25 are arranged in parallel and connected to the rotating rod 23 respectively through the transmission mechanism 24. A single rotating rod 23 can drive several stirring rods 25 to rotate synchronously, so that multiple containers 10 can be stirred synchronously. In this embodiment, two stirring rods 25 are provided.

[0029] Furthermore, the transmission mechanism 24 is mounted on the mounting base 4, which is located above and spaced apart from the base 1. The lifting assembly 3 includes a driver 31 and a lifting rod 32 connected to the driver 31. The driver 31 is mounted on the base 1, and one end of the lifting rod 32 is connected to the driver 31, while the other end is connected to the mounting base 4. Power is provided by the driver 31 to raise and lower the lifting rod 32, thereby driving the mounting base 4 to rise and fall, enabling the transmission mechanism 24 to move up and down. The lifting assembly 3 in this embodiment can use existing lifting devices such as screw jacks, worm gear jacks, or electric telescopic rods. In this embodiment, the driver 31 is a cylinder, which is connected to the lifting rod 32. The raising and lowering of the lifting rod 32 is controlled by the telescopic rod of the cylinder 31. In this embodiment, the stirring rod 25, the rotating rod 23, and the lifting rod 32 are arranged in parallel.

[0030] Furthermore, the transmission mechanism 24 includes a transmission gear 241, with each stirring rod 25 connected to the transmission gear 241, and the transmission gear 241 sleeved on the stirring rod 25. The rotating rod 23 is provided with a drive gear 232, which meshes with the transmission gear 241, thereby driving the drive gear 232 to rotate through the rotating rod 23, which in turn drives the transmission gear 241 and the stirring rod 25 to rotate.

[0031] <Example 2> In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0032] like Figures 6 to 9 As shown, compared to Embodiment 1, the stirring device for grinding wheels provided in this embodiment has the following structural design differences: In this embodiment, a stirrer 5 is provided at the bottom of the stirring rod 25. The stirrer 5 corresponds to the container 10 on the base 1, and the stirring 5 can improve the mixing efficiency of the materials in the container 10. The stirrer 5 includes a sleeve part 51, a fixing plate 52, and a movable part 53. The sleeve part 51 is detachably connected to the stirring rod 25. Specifically, the sleeve part 51 has a mounting hole 511. The end of the stirring rod 25 is inserted into the mounting hole 511, and the sleeve part 51 is locked from the side by a screw 512, which facilitates installation and disassembly. The fixing plate 52 is provided around the sleeve part 51, and the movable part 53 has a strip groove 531. The movable part 53 and the fixing plate 52 are connected by the strip groove 531 and the fixing assembly 54. By providing the strip groove 531, the displacement between the movable part 53 and the fixing plate 52 can be adjusted to suit containers 10 of different diameters. Through the above technical solution, the stirrer 5 can be replaced according to different stirring requirements, or the position of the movable part 53 can be adjusted to suit containers of different sizes.

[0033] Specifically, the fixing plate 52 has a positioning groove 521, and a through hole 522 is provided in the positioning groove 521. The movable member 53 is disposed in the positioning groove 521. The fixing assembly 54 includes a fixing member 541, which passes through the strip groove 531 and the through hole 522. When the movable member 53 is adjusted to the correct position, the fixing member 541 passes through the strip groove 531 and the through hole 522, locking the movable member 53 and the fixing plate 52. In this embodiment, the fixing member 541 includes a bolt, which is locked in place with a nut.

[0034] In this embodiment, the drive mechanism is mounted on the base and is separated from the transmission mechanism of the stirring rod. When the stirring rod is raised and lowered, the drive mechanism does not need to move accordingly, reducing the load on the lifting component. At the same time, multiple stirring rods can be used to stir simultaneously, improving stirring efficiency. In addition, the stirrer can be adjusted according to different containers to obtain better stirring results.

[0035] In the above embodiments one and two, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one and two can be combined or replaced.

[0036] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
