Technical Field
[0001] The utility model relates to the technical field of mixing equipment, in particular to a raw material mixing equipment for producing resin grinding wheels. Background Art
[0002] Grinding wheels are important cutting tools made of abrasives and used on grinding machines. Grinding wheels of different materials need to be selected according to the material, hardness, grinding amount and precision requirements of the workpiece. For example, resin grinding wheels are made of resin, which have certain elasticity, low heat resistance, good self-sharpening and are easy to make.
[0003] In the production process of resin grinding wheels, it is usually necessary to mix a variety of raw materials. However, most of the existing mixing equipment usually uses centrifugal force to mix the raw materials during the mixing process. In this way, during the mixing process, the resin is easily attached to the inner wall of the container due to the influence of centrifugal force, thus causing uneven mixing. Therefore, a raw material mixing equipment for resin grinding wheel production is proposed to solve the above problem. Utility Model Content
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a raw material mixing device for the production of resin grinding wheels, which can solve the problem that most of the existing mixing devices usually use centrifugal force to mix the raw materials during the mixing process. In this way, during the mixing process, the resin is easily attached to the inner wall of the container due to the influence of centrifugal force, thus causing uneven mixing.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material mixing device for producing resin grinding wheels, comprising a mixing barrel, support legs are fixedly connected to both sides of the mixing barrel, a driving motor is fixedly connected to the upper end of the mixing barrel, a discharge pipe that is interconnected with the lower end of the mixing barrel is fixedly connected, and a valve is arranged on the discharge pipe;
[0006] The interior of the mixing barrel is rotatably connected with a stirring shaft, and the stirring shaft is fixedly connected to the output end of the driving motor;
[0007] The mixing mechanism is arranged on the stirring shaft, and the resin raw materials can be mixed and stirred by the mixing mechanism, and the phenomenon of uneven mixing of the resin raw materials in a centrifugal state can be avoided.
[0008] Preferably, the mixing mechanism comprises two movable rings, and the two movable rings are respectively slidably connected to the stirring shaft;
[0009] Two inclined tie rods are rotatably connected to the two moving rings respectively, and opposite ends of the two inclined tie rods on the two moving rings are rotatably connected together;
[0010] An N-shaped rotating support is rotatably connected to one end of the two inclined tie rods;
[0011] The rotating supports are all fixedly connected with a pushing mixing plate;
[0012] When the stirring shaft rotates, the moving ring and the inclined rod are driven to rotate simultaneously, so the inclined rod can play a preliminary stirring effect.
[0013] Preferably, a stirring limit groove is provided on the stirring shaft, and stirring limit blocks are fixedly connected to the two movable rings, and the stirring limit blocks are slidably connected to the inside of the stirring limit groove.
[0014] Preferably, a return spring is fixedly connected to the stirring limit block, and the other end of the return spring is fixedly connected to the inside of the stirring limit groove.
[0015] Preferably, two stirring movable grooves are provided on the inner wall of the mixing barrel, and stirring limit rods are fixedly connected to the two movable rings;
[0016] A rolling ball is fixedly connected to one end of the stirring limit rod that is not in contact with the moving ring, and the rolling ball is slidably connected to the inside of the stirring moving tank.
[0017] Preferably, the two stirring and moving grooves are both annular wave-shaped.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] (1) In the raw material mixing equipment for producing resin grinding wheels, when the stirring shaft rotates, the moving ring rotates together under the restriction of the stirring limit block. At this time, the stirring limit rod and the rolling ball slide inside the stirring moving groove. Since the stirring moving groove is wavy and undulating, the moving ring slides on the stirring shaft during rotation, thereby changing the angle between the inclined rods, thereby causing the pushing mixing plate to continuously push the resin raw material inside the mixing barrel. Therefore, it can effectively avoid the resin raw material from rotating against the inner wall of the mixing barrel under the action of centrifugal force, thereby ensuring the mixing effect of the resin raw material.
[0020] (2) The raw material mixing equipment for producing resin grinding wheels is connected by sliding through the stirring limit groove and the stirring limit block, so that the stirring shaft can effectively drive the moving ring to rotate when the stirring shaft rotates.

[0034] Furthermore, the mixing mechanism comprises two movable rings 7, and the two movable rings 7 are respectively slidably connected to the stirring shaft 6;
[0035] Two inclined tie rods 8 are rotatably connected to the two moving rings 7, and opposite ends of the two inclined tie rods 8 on the two moving rings 7 are rotatably connected together;
[0036] An N-shaped rotating support 10 is rotatably connected to one end of the two inclined tie rods 8;
[0037] The rotating supports 10 are all fixedly connected with a pushing mixing plate 9;
[0038] When the stirring shaft 6 rotates, the moving ring 7 and the inclined rod 8 are driven to rotate simultaneously, so the inclined rod 8 can play a preliminary stirring effect.
[0039] Furthermore, a stirring limit groove 14 is provided on the stirring shaft 6, and stirring limit blocks 16 are fixedly connected to the two movable rings 7, and the stirring limit blocks 16 are slidably connected to the inside of the stirring limit groove 14;
[0040] By the sliding connection of the stirring limit groove 14 and the stirring limit block 16, the movable ring 7 is limited by the stirring shaft 6, so that the movable ring 7 can be effectively driven to rotate when the stirring shaft 6 rotates.
[0041] Furthermore, a return spring 15 is fixedly connected to the stirring limit block 16, and the other end of the return spring 15 is fixedly connected to the inside of the stirring limit groove 14;

Therefore, it can effectively avoid the resin raw material from rotating against the inner wall of the mixing barrel 1 under the action of centrifugal force, thereby ensuring the mixing effect of the resin raw material.
