Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, in particular to a feeding mechanism of a rotary press for resin grinding wheels. Background Technique

[0002] A resin grinding wheel is a grinding wheel made of resin, with high strength, and is used in cutting discs, double-sided grinding wheels, heavy-duty grinding wheels, polishing wheels, etc. It has certain elasticity, low heat resistance, good self-sharpening property, is easy to manufacture, and has a short process cycle; it is widely used in rough grinding, snag grinding, cutting, and free grinding, such as grinding steel ingots and deburring castings; during the production process of resin grinding wheels, generally, it needs to go through the processes of auxiliary material preparation, mixing of abrasives and auxiliary materials, pressing into shape, hardening, and inspection. When forming with a rotary press, it is necessary to first pour the mixed material into a sieve barrel through a device with a vibration screening function for vibration screening and feeding, and then convey the qualified mixed material separated by screening to the designated die station of the rotary press to complete the feeding operation.

[0003] For example, the disclosed document with the application number 202121419820.6 discloses a feeding mechanism of a rotary press for resin grinding wheels. This utility model conducts the first screening process on the mixed material through the internally provided sieve mesh part, can directly screen out unqualified mixed material, reduce the deposition amount of unqualified material inside the barrel, reduce the cleaning frequency, and thus improve production efficiency. However, for this feeding mechanism of the rotary press for resin grinding wheels, when the material is poured above the sieve mesh, it is necessary to manually spread the material, and the uniformity of spreading is not high, which affects the screening efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a feeding mechanism of a rotary press for resin grinding wheels is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding mechanism of a rotary press for resin grinding wheels to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A feeding mechanism of a rotary press for resin grinding wheels, including a material barrel, a triangular cross frame is horizontally and fixedly installed in the middle above the inner surface of the material barrel, a driving motor is fixedly arranged in the middle below the surface of the triangular cross frame, blocking plates are fixedly installed on both the left and right sides below the surface of the triangular cross frame, a sieve mesh is arranged at the bottom end of the driving motor, there is a slight gap between the upper surface of the sieve mesh and the bottom ends of the blocking plates, and a discharge port is arranged at the bottom end of the material barrel.

[0007] Preferably, a ring plate is fixedly sleeved on the outer side of the surface of the sieve mesh, and a sealing ring is fixedly installed above the surface of the ring plate.

[0008] Preferably, a ring groove is formed in the middle of the outer side of the ring plate, and bumps are fixedly installed on the inner surface of the ring groove in a uniform distribution.

[0009] Preferably, the surface of the bump on the side rotating in the same direction as the driving motor is set as an inclined surface, and the periphery of the surface of the sealing ring is in sliding fit with the inner surface of the barrel.

[0010] Preferably, a groove is formed in the inner surface of the barrel, and the position of the groove corresponds horizontally to the position of the ring plate.

[0011] Preferably, spring rods are fixedly installed on the inner surface of the groove in a uniform distribution, a top block is fixedly arranged at the end of the spring rod, and the top block extends out of the groove and is located inside the ring groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the settings of the triangular cross frame, driving motor, baffle plate and sieve mesh in the present utility model, materials are poured into the barrel from the upper opening and received by the sieve mesh. The tip at the upper end of the triangular cross frame prevents materials from accumulating on the triangular cross frame, ensuring that the materials can fall completely. The driving motor can drive the sieve mesh to rotate, and the centrifugal force is used to spread the accumulated materials outward and disperse them. At the same time, the relative movement between the baffle plate and the sieve mesh can also assist in dispersing the materials, automatically and quickly spreading the materials flat, without the need for manual operation to separate the materials, making full use of each pore of the sieve mesh for screening, improving the work efficiency and reducing the manual labor intensity;

[0014] 2. Through the setting of the sealing ring in the present utility model, the sealing ring prevents materials from falling through the edge joint between the ring plate and the barrel, and also prevents the situation that the sieve mesh throws the materials to the edge joint when rotating, ensuring that the materials can be effectively spread flat above the surface of the sieve mesh;

[0015] 3. Through the settings of the ring plate, ring groove, bump, groove, spring rod and top block in the present utility model, the rotation of the sieve mesh will also drive the ring plate to rotate, and the bumps inside the ring groove will move accordingly. The inclined surface is used to push the top block to squeeze the spring rod to contract. When the spring rod is located in the gap between the bumps, it will push the top block to reset again and collide with the ring plate, causing the entire sieve mesh to vibrate, thereby improving the screening efficiency of the sieve mesh and also avoiding the blockage of the sieve mesh.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model

[0022] As Figures 1-4 shown, a feeding mechanism of a rotary press for resin grinding wheels includes a barrel 1. A triangular cross-frame 2 is horizontally and fixedly installed in the middle above the inner surface of the barrel 1. A drive motor 3 is fixedly arranged in the middle below the surface of the triangular cross-frame 2. Baffle plates 4 are fixedly installed on both the left and right sides below the surface of the triangular cross-frame 2. A screen 5 is arranged at the bottom end of the drive motor 3. There is a slight gap between the upper surface of the screen 5 and the bottom end of the baffle plate 4. A discharge port 13 is arranged at the bottom end of the barrel 1

[0023] By adopting the above technical solutions, the tip at the upper end of the triangular cross-frame 2 prevents materials from accumulating on the triangular cross-frame 2, ensuring that the materials can fall completely; the drive motor 3 can drive the screen 5 to rotate, and the centrifugal force is used to spread the accumulated materials outward and disperse them; the relative movement between the baffle plate 4 and the screen 5 can also assist in dispersing the materials and automatically and quickly spread the materials flat

[0024] Furthermore, a ring plate 6 is fixedly sleeved on the outer side of the surface of the screen 5, and a sealing ring 7 is fixedly installed above the surface of the ring plate 6

[0025] By adopting the above technical solutions, the sealing ring 7 prevents materials from falling through the joint between the ring plate 6 and the edge of the barrel 1, and also prevents the situation that the screen 5 throws the materials to the edge joint when rotating, ensuring that the materials can be effectively spread flat above the surface of the screen 5

[0026] Furthermore, an annular groove 8 is opened in the middle of the outer side of the ring plate 6, and convex blocks 9 are fixedly installed on the inner surface of the annular groove 8 at equal intervals

[0027] By adopting the above technical solutions, the ring plate 6 can rotate synchronously with the screen 5

[0028] Furthermore, the surface of the bump 9 on the side rotating in the same direction as the driving motor 3 is set as an inclined surface, and the periphery of the surface of the sealing ring 7 fits and slides with the inner surface of the barrel 1.

[0029] Furthermore, a groove 10 is formed on the inner surface of the barrel 1, and the position of the groove 10 corresponds horizontally to the position of the ring plate 6.

[0030] Furthermore, spring rods 11 are fixedly installed on the inner surface of the groove 10 in a uniform distribution. The end of the spring rod 11 is fixedly provided with a top block 12, and the top block 12 extends out of the groove 10 and is located inside the annular groove 8.

[0031] By adopting the above technical solution, the bump 9 inside the annular groove 8 will move accordingly. The inclined surface is used to push the top block 12 to squeeze the spring rod 11 to contract. When the spring rod 11 is located in the gap between the bumps 9, it will push the top block 12 to reset again and collide with the ring plate 6, causing the entire screen 5 to vibrate, thereby improving the screening efficiency of the screen 5.

[0032] Working principle: When using the feeding mechanism of the rotary press for resin grinding wheels, first, the material is poured into the barrel 1 from the upper opening and is received by the screen 5. The tip at the upper end of the triangular cross frame 2 prevents the material from accumulating on the triangular cross frame 2, ensuring that the material can fall completely. The driving motor 3 can drive the screen 5 to rotate, and the centrifugal force is used to spread the accumulated material outward and disperse it. At the same time, the blocking plate 4 moves relative to the screen 5, which can also assist in dispersing the material and automatically spread the material quickly and evenly. The rotation of the screen 5 will also drive the ring plate 6 to rotate. The bump 9 inside the annular groove 8 will move accordingly. The inclined surface is used to push the top block 12 to squeeze the spring rod 11 to contract. When the spring rod 11 is located in the gap between the bumps 9, it will push the top block 12 to reset again and collide with the ring plate 6, causing the entire screen 5 to vibrate, thereby improving the screening efficiency of the screen 5. During the spreading process, the sealing ring 7 prevents the material from falling through the edge joint between the ring plate 6 and the barrel 1, and also prevents the situation where the screen 5 throws the material to the edge joint when rotating, ensuring that the material can be effectively spread above the surface of the screen 5. This is the working principle of the feeding mechanism of the rotary press for resin grinding wheels.
