Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding device with graded grinding. Background Art

[0002] In the production of calcium carbonate, a grinding device with graded grinding can perform the functions of grinding and particle size classification to meet the different particle size requirements of calcium carbonate powder. This device usually combines grinding and screening technology, so that the calcium carbonate ore can be further ground into powder of the required particle size after crushing, and the powder is screened through a grading system to achieve precise particle size control.

[0003] The existing grinding device can grind calcium carbonate ore into different particles, but if you want more fine particles, or want to further refine the particles to make the product particle size distribution more uniform, the staff needs to collect the ground calcium carbonate particles and then pour them into the feed port of the grinding device, which is not only time-consuming and labor-intensive but also reduces work efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a grinding device with graded grinding to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides a grinding device with graded grinding, including a grinder body and a base. A conveying assembly is installed on one side of the grinder body, and the conveying assembly includes a servo motor. The driving end of the servo motor is connected to a worm, and the worm is meshingly connected to a worm wheel. A lead screw is installed on the worm wheel. A slider is threadedly connected to the outer wall of the lead screw, and an arc-shaped receiving box is rotatably connected to the slider. A first arc-shaped plate is installed on one side of the arc-shaped receiving box, and a second arc-shaped plate is arranged on one side of the first arc-shaped plate.

[0006] Furthermore, the two screw rods are rotatably connected to the base, a mounting frame is installed on the top of the base, and the top end of the screw rod is rotatably connected to the inner top wall of the mounting frame.

[0007] Furthermore, an L-shaped rod is installed on the top of the grinder body, a cylindrical block is installed on the side wall of the arc-shaped receiving box, and a screening device is provided on the inner wall of the grinder body.

[0008] Furthermore, the worm is rotatably connected to the mounting frame, and a counterweight is installed at the bottom of the arc-shaped receiving box.

[0009] Furthermore, a telescopic spring and a button are installed on the inner wall of the arc-shaped receiving box, a mounting block is installed on the other end of the telescopic spring, the button is arranged on one side of the mounting block, and an alarm device is installed on the outer wall of the grinder body.

[0010] Furthermore, a telescopic rod is installed between the arc-shaped receiving box and the mounting block, and the telescopic spring is arranged on the outer wall of the telescopic rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the present utility model, under certain circumstances, calcium carbonate may need to be reground after being ground. An arc-shaped receiving box is provided next to the screening device, and the calcium carbonate particles enter this box after being screened. The servo motor is started by the single-chip microcomputer, and the motor drives the worm to rotate, and the worm engages with the worm wheel, thereby driving the lead screw to rotate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] Embodiment 1:

[0025] See also Figure 1-4 A grinding device with graded grinding includes a grinder body 1 and a base 13. A conveying assembly 2 is installed on one side of the grinder body 1. The conveying assembly 2 includes a servo motor 201. A worm 202 is connected to the driving end of the servo motor 201. The worm 202 is meshingly connected to a worm wheel 203. A lead screw 204 is fixedly installed on the worm wheel 203. A slider 205 is threadedly connected to the outer wall of the lead screw 204. An arc-shaped receiving box 206 is rotatably connected to the slider 205. A first arc-shaped plate 207 is fixedly installed on one side of the arc-shaped receiving box 206. A second arc-shaped plate 208 is arranged on one side of the first arc-shaped plate 207.

[0026] In some special cases, after the calcium carbonate is ground in the grinding machine body 1, it may be necessary to regrind it. The arc receiving box 206 is arranged on one side of the screening device 12. The calcium carbonate particles enter the arc receiving box 206 along the screening device 12. The servo motor 201 is started by controlling the single chip microcomputer. The driving end of the servo motor 201 drives the worm 202 to rotate. The worm 202 is meshed with the worm wheel 203. The worm 202 drives the screw 204 to rotate through the worm wheel 203. The screw 204 drives the slider 205 and the arc receiving box 206. The arc-shaped receiving box 206 moves upward in the vertical direction. When the arc-shaped receiving box 206 moves to a certain height, the extended first arc plate 207 will be pressed against the second arc plate 208 on the side of the feed port on the grinder body 1 and flipped toward the feed port. The calcium carbonate particles in the arc-shaped receiving box 206 will be poured into the feed port for grinding again. There is no need for staff to collect the calcium carbonate particles and then pour the calcium carbonate particles into the feed port. The conveying component 2 greatly improves the efficiency of regrinding the calcium carbonate particles.

[0027] See also Figure 1-2 The two screw rods 204 are rotatably connected to the base 13 , a mounting frame 8 is fixedly mounted on the top of the base 13 , and the top end of the screw rods 204 is rotatably connected to the inner top wall of the mounting frame 8 .

[0028] The base 13 provides a stable support for the screw rod 204, ensuring that the screw rod 204 can rotate stably during operation. The mounting frame 8 further enhances the stability of the top of the screw rod 204, preventing it from shaking or deflecting during operation, thereby ensuring the accuracy and stability of the mechanical movement.

[0029] See also Figure 2 An L-shaped rod 9 is fixedly installed on the top of the grinder body 1, a cylindrical block 10 is fixedly installed on the side wall of the arc-shaped receiving box 206, and a screening device 12 is provided on the inner wall of the grinder body 1.

[0030] When the arc-shaped receiving box 206 tilts and rotates, when the arc-shaped receiving box 206 rotates to a certain extent, the cylindrical block 10 will resist the L-shaped rod 9 to prevent the arc-shaped receiving box 206 from being overturned. If an overturning occurs, the staff may be required to rotate it, increasing the workload of the staff.

[0031] See also Figure 3-4 The worm 202 is rotatably connected to the mounting frame 8 , and a counterweight 11 is fixedly mounted on the bottom of the arc-shaped receiving box 206 .

[0032] The mounting frame 8 provides good support for the slider 205 . When the arc-shaped receiving box 206 moves downward, the first arc-shaped plate 207 and the second arc-shaped plate 208 are pulled apart for a distance, and then the counterweight 11 can better restore the state in which the opening faces upward.

[0033] Embodiment 2:

[0034] See also Figure 5 A telescopic spring 3 and a button 6 are fixedly installed on the inner wall of the arc-shaped receiving box 206, a mounting block 5 is fixedly installed on the other end of the telescopic spring 3, the button 6 is arranged on one side of the mounting block 5, and an alarm device 7 is fixedly installed on the outer wall of the grinder body 1.

[0035] When the arc-shaped receiving box 206 receives calcium carbonate particles, after the calcium carbonate particles are collected to a certain extent, the calcium carbonate particles will squeeze the mounting block 5, and the telescopic spring 3 will be compressed under the force, and the telescopic spring 3 will drive the mounting block 5 to move toward the button 6 and squeeze the button 6, and then the alarm device 7 will sound an alarm, prompting the staff to stop discharging at the feed port, which can help the staff not to always pay attention to the situation of the arc-shaped receiving box 206 collecting calcium carbonate particles.

[0036] When the alarm device 7 sounds, the staff will push away the calcium carbonate particles next to the mounting block 5, the alarm device 7 stops sounding the alarm, and then starts the servo motor 201.

[0037] See also Figure 1 - Figure 5 A telescopic rod 4 is fixedly installed between the arc-shaped receiving box 206 and the mounting block 5, and the telescopic spring 3 is arranged on the outer wall of the telescopic rod 4.

[0038] The telescopic rod 4 can shrink along with the shrinkage of the telescopic spring 3, and can prevent smaller calcium carbonate particles from entering the interior of the spring. Then the staff is required to take out the calcium carbonate particles therefrom, which increases the workload.

[0039] Working principle: In some special cases, after the calcium carbonate is ground in the grinding machine body 1, it may be necessary to regrind it. The arc receiving box 206 is set on one side of the screening device 12. The calcium carbonate particles enter the arc receiving box 206 along the screening device 12. The servo motor 201 is started by controlling the single chip microcomputer. The driving end of the servo motor 201 drives the worm 202 to rotate. The worm 202 is meshed with the worm wheel 203. The worm 202 drives the screw 204 to rotate through the worm wheel 203. The screw 204 drives the slider 20 5. The arc-shaped receiving box 206 moves upward in the vertical direction. When the arc-shaped receiving box 206 moves to a certain height, the extended first arc-shaped plate 207 will be pressed against the second arc-shaped plate 208 on the side of the feed port on the grinder body 1 and flipped toward the feed port. The calcium carbonate particles in the arc-shaped receiving box 206 will be poured into the feed port and ground again. There is no need for staff to collect the calcium carbonate particles and then pour them into the feed port. The conveying component 2 greatly improves the efficiency of regrinding the calcium carbonate particles.

[0040] When the arc-shaped receiving box 206 receives calcium carbonate particles, after the calcium carbonate particles are collected to a certain extent, the calcium carbonate particles will squeeze the mounting block 5, and the telescopic spring 3 will be compressed under the force, and the telescopic spring 3 will drive the mounting block 5 to move toward the button 6 and squeeze the button 6, and then the alarm device 7 will sound an alarm, prompting the staff to stop discharging at the feed port, which can help the staff not to always pay attention to the situation of the arc-shaped receiving box 206 collecting calcium carbonate particles.

[0041] When the alarm device 7 sounds, the staff will push away the calcium carbonate particles next to the mounting block 5, the alarm device 7 stops sounding the alarm, and then starts the servo motor 201.
