Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine feeding mechanism. Background Technology

[0002] A grinding machine is a grinding machine that uses abrasive-coated or embedded grinding tools to grind the surface of a workpiece. The main types of grinding machines include disc grinding machines, twin-spindle grinding machines, and various special-purpose grinding machines. Twin-spindle grinding machines improve grinding efficiency by driving two grinding shafts to grind simultaneously.

[0003] However, in the case of a dual-shaft grinding mill, it is difficult to precisely control factors such as temperature and pressure during the grinding process. This can cause blockages in the grinding shaft, resulting in uneven grinding of materials and particle sizes that need to be further screened.

[0004] Existing dual-shaft grinding mills typically have a screen at the feeding point for further screening of materials. However, the screen is prone to clogging due to material accumulation, which in turn affects the subsequent screening and discharge of materials. Therefore, a new feeding mechanism for the grinding mill is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing dual-shaft grinding mills usually have a screen installed at the feeding point to further screen the material. However, the screen is prone to clogging due to material accumulation, which in turn affects the subsequent screening and discharge of materials. This utility model proposes a feeding mechanism for a grinding mill.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a grinding machine feeding mechanism of this utility model includes a grinding barrel; a discharge pipe is fixedly installed at the bottom of the grinding barrel, a baffle is fixedly installed inside the discharge pipe, a sieve hole is opened on the baffle, and a bracket is fixedly installed at the bottom of the grinding barrel.

[0007] A cleaning mechanism is provided on the baffle. The cleaning mechanism includes a drive block fixedly installed at the bottom of the baffle. A motor is fixedly connected to the inner bottom wall of the drive block. A partition is fixedly connected inside the drive block. The output end of the motor passes through a through hole in the partition and is connected to a drive rod via a coupling. The top end of the drive rod passes through the drive block and the baffle in sequence and is connected to a rolling rod. An air jet hole is provided on the rolling rod. An injection groove is provided inside the rolling rod. The injection groove communicates with the drive groove on the drive rod. A support plate is fixedly connected to the drive rod on the rod wall inside the drive block. An air pump is fixedly connected to the top of the support plate. An air inlet is provided on the rod wall inside the drive block. The air outlet of the air pump is connected to the air inlet of the drive rod via a conduit.

[0008] Preferably, the jet holes are provided in several groups, and the several groups of jet holes are equidistantly distributed, and a filter screen is provided on the jet holes.

[0009] Preferably, the rolling rods are provided in three sets, and the three sets of rolling rods are distributed at equal intervals. The air jets are inclined, and the inclination of the air jets is opposite to the rotation of the rolling rods.

[0010] Preferably, a retaining ring is fixedly connected to the top of the baffle, a sealing gasket is provided on the top of the retaining ring, and a sealing gasket is provided between the drive rod and the baffle.

[0011] Preferably, the outer surface of the discharge pipe is provided with a sound-insulating coating, and the inner wall of the discharge pipe is provided with a wear-resistant layer.

[0012] Preferably, the support plate is located above the partition, and a blocking ring is rotatably mounted on the partition, with the top of the blocking ring fixedly connected to the bottom of the support plate.

[0013] The advantages of this utility model are:

[0014] 1. This utility model, through the setting of the cleaning mechanism, starts the motor located in the drive block. The motor drives the drive rod to rotate, and the drive rod drives the support plate to rotate, while simultaneously driving the grinding roller connected to its top to rotate, thus performing secondary grinding on the material falling on the baffle, which initially facilitates the material to be discharged through the sieve holes.

[0015] 2. This utility model activates an air pump located within the drive block, allowing high-pressure gas to be introduced into the drive groove within the drive rod via a conduit. The high-pressure gas then travels through the drive groove into multiple interconnected spray grooves, and is discharged through air jets to blow high-pressure air onto the material and powder clogging the screen holes. This blows up the material and powder blocking the screen holes, facilitating their passage through the screen and solving the problem of screen blockage caused by material accumulation, which in turn affects subsequent material screening and discharge.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4 As shown, a grinding mill feeding mechanism includes a grinding barrel 1; a discharge pipe 2 is fixedly installed at the bottom of the grinding barrel 1, a baffle 3 is fixedly installed inside the discharge pipe 2, a sieve hole 4 is opened on the baffle 3, and a bracket 5 is fixedly installed at the bottom of the grinding barrel 1.

[0026] A cleaning mechanism 6 is provided on the baffle 3. The cleaning mechanism 6 includes a drive block 61 fixedly installed at the bottom of the baffle 3. A motor 62 is fixedly connected to the inner bottom wall of the drive block 61. A partition 65 is fixedly connected inside the drive block 61. The output end of the motor 62 passes through a through hole in the partition 65 and is fixedly connected to a drive rod 63 via a coupling. The top end of the drive rod 63 passes through the drive block 61 and the baffle 3 in sequence and is fixedly connected to a crushing rod 64. An air jet hole 66 is provided on the crushing rod 64, and an injection groove is provided inside the crushing rod 64. The injection groove is connected to the drive rod 63. The drive slot 67 is connected, and the drive rod 63 is mounted on the rod wall inside the drive block 61 with a fixed support plate 610. An air pump 69 is fixedly connected to the top of the support plate 610. An air inlet is provided on the rod wall inside the drive block 61 of the drive rod 63, and the air outlet of the air pump 69 is connected to the air inlet of the drive rod 63 via a conduit 68. During operation, existing dual-shaft grinding mills typically have a screen at the feeding point for further screening of materials. However, the screen is prone to clogging due to material accumulation, which affects subsequent material screening and discharge. Therefore, this device is used. Specifically, when the material passes through… After being ground by the grinding components in the grinding barrel 1, the material falls into the discharge pipe 2, then onto the baffle 3, and passes through the sieve holes 4 on the baffle 3. The cleaning mechanism 6 facilitates further crushing of the material that has not reached the required pulverization level on the baffle 3, while simultaneously cleaning up any material and powder clogging the sieve holes 4, ensuring normal material feeding. Specifically, the motor 62 located in the drive block 61 is activated, driving the drive rod 63 to rotate. The drive rod 63, in turn, drives the support plate 610 to rotate, simultaneously rotating the crushing roller connected to its top, thus performing secondary grinding on the material falling onto the baffle 3, facilitating the material's passage through the sieve holes 4. Simultaneously, the air pump 69 located in the drive block 61 starts, and high-pressure gas is introduced into the drive groove 67 in the drive rod 63 through the conduit 68. Then, the high-pressure gas is introduced into multiple spray grooves connected to it through the drive groove 67, and is discharged through the air jet hole 66 to blow the material and powder blocking the screen hole 4 under high pressure, so that the material and powder blocking the screen hole 4 are blown away, which facilitates the subsequent material feeding and discharge. This solves the problem that the existing double-shaft grinding mill usually sets a screen at the feeding point to further screen the material, but the screen is easily blocked by the accumulation of material, which affects the subsequent screening and discharge of material.

[0027] The jet holes 66 are provided in several groups, and the groups of jet holes 66 are equidistantly distributed. A filter screen is provided on the jet holes 66. During operation, by providing a filter screen on the jet holes 66, the material and powder that are blown up are prevented from being guided into the spray tank through the jet holes 66, thus avoiding blockage.

[0028] The rolling rods 64 are provided in three sets, and the three sets of rolling rods 64 are equally distributed. The air jet holes 66 are inclined, and the inclination direction of the air jet holes 66 is opposite to the rotation direction of the rolling rods 64. During operation, the inclined air jet holes 66, with the inclination direction of the air jet holes 66 being opposite to the rotation direction of the rolling rods 64, facilitate the blowing of material and powder, and at the same time provide further kinetic energy for the rotation of the rolling rods 64.

[0029] A retaining ring 7 is fixedly connected to the top of the baffle 3, and a sealing gasket is provided on the top of the retaining ring 7. A sealing gasket is also provided between the drive rod 63 and the baffle 3. During operation, the sealing between the baffle 3 and the drive rod 63 is enhanced by the retaining ring 7 fixedly connected to the top of the baffle 3, the sealing gasket on the top of the retaining ring 7, and the sealing gasket between the drive rod 63 and the baffle 3.

[0030] The outer surface of the discharge pipe 2 is provided with a sound-insulating coating, and the inner wall of the discharge pipe 2 is provided with a wear-resistant layer. During operation, the sound-insulating coating on the outer surface of the discharge pipe 2 reduces the noise generated by the collision between the blown material and the discharge pipe 2, while the wear-resistant layer on the inner wall of the discharge pipe 2 enhances the wear resistance of the inner wall of the discharge pipe 2.

[0031] The support plate 610 is located above the partition plate 65. A baffle ring 8 is rotatably mounted on the partition plate 65. The top of the baffle ring 8 is fixedly connected to the bottom of the support plate 610. During operation, the baffle ring 8 ensures that the support plate 610 is in operation.

[0032] Example 2

[0033] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the discharge pipe 2 is provided with an inspection port, and an inspection cover 9 is movably installed in the inspection port via a hinge. During operation, the inspection port on the discharge pipe 2 and the inspection cover 9 movably installed in the inspection port via a hinge facilitate the maintenance of the cleaning mechanism 6 located in the discharge pipe 2, thereby improving the service life of the device.

[0034] Working principle: After the material is ground by the grinding components in the grinding barrel 1, it falls into the discharge pipe 2 and then onto the baffle 3. It then passes through the sieve holes 4 on the baffle 3. The cleaning mechanism 6 facilitates further crushing of the material that has not reached the required pulverization level on the baffle 3, while also cleaning up the material and powder clogging the sieve holes 4, ensuring normal material feeding. Specifically, the motor 62 located in the drive block 61 is activated. The motor 62 drives the drive rod 63 to rotate, which in turn drives the support plate 610 to rotate, simultaneously rotating the crushing roller connected to its top. This performs secondary grinding on the material falling onto the baffle 3, facilitating material passage. The gas exits through the sieve hole 4, and at the same time, the air pump 69 located in the drive block 61 starts. High-pressure gas is introduced into the drive groove 67 in the drive rod 63 through the conduit 68. Then, the high-pressure gas is introduced into multiple spray grooves connected to it through the drive groove 67, and is discharged through the air jet hole 66 to blow the material and powder blocking the sieve hole 4 under high pressure. This blows up the material and powder blocking the sieve hole 4, which facilitates the subsequent material feeding and discharge. This solves the problem that existing dual-shaft grinding mills usually set up a screen at the feeding point to further screen the material, but the screen is easily blocked by the accumulation of material, which affects the subsequent screening and discharge of material.
