Description

Technical Field

[0001] The present invention relates to the field of grinding equipment, in particular to an electric carbon product grinding equipment. Background Art

[0002] Electrical carbon products are conductive materials made from carbon and graphite materials. They are widely used in power transmission, motor equipment, electric locomotives, communication equipment and other fields. Their core characteristics include high conductivity, high temperature resistance and stable chemical properties. The product forms include brushes, carbon slides, contacts, electrodes and other types, which can meet the functional requirements of different conductive components in industrial scenarios.

[0003] The electric carbon product grinding equipment and method is a mechanical equipment specially used for grinding electric carbon materials. It can grind the electric carbon raw materials into the required fine powder or granular materials. This type of equipment is widely used in the production field of electric carbon products, such as the manufacture of motor carbon brushes, graphite electrodes and other products. The working principle of the electric carbon product grinding equipment and method mainly involves the friction and collision between the grinding medium and the raw material. During the rotation of the grinding cylinder, the grinding medium and the raw material continuously rub and collide with the inner wall of the grinding cylinder and other grinding media, so that the raw material is gradually ground into the required fine powder or granular materials.

[0004] In the prior art, when using grinding equipment to grind electric carbon products, the electric carbon raw materials are usually placed into the equipment manually, and then the equipment is started to grind the electric carbon raw materials. When grinding the electric carbon raw materials, multiple grinding steps are required to complete the grinding of the raw materials. After the grinding is completed, the electric carbon raw materials also need to be taken out of the equipment manually. The overall operation process requires many processes of manual intervention. When manually discharging the materials, the electric carbon raw materials are generally placed in large quantities into the equipment. In this case, it is also easy to cause blockage inside the equipment. In addition, the sizes of the electric carbon raw materials are also different, which will cause some of the electric carbon raw materials to not be fully ground, thereby resulting in a decrease in grinding quality. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an electric carbon product grinding equipment to solve the technical problems that manual loading and unloading of raw materials is required during grinding, and manual loading of large quantities of raw materials at one time may cause blockage inside the equipment, and raw materials of different sizes cannot be fully ground inside the equipment.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an electric carbon product grinding device, comprising a machine body, a crushing mechanism is provided on the top of the machine body, a conveying mechanism is installed at the bottom of the crushing mechanism, a feeding mechanism is provided between the conveying mechanism and the machine body, a grinding mechanism is installed inside the machine body, the conveying mechanism comprises a conveying motor, a first spiral blade, a second spiral blade, a cam, a driving block and a movable plate, wherein the conveying motor is installed on the top of the machine body, and the output end of the conveying motor is fixedly connected to the first spiral blade, the end of the first spiral blade is movably connected to the second spiral blade, the cam is fixedly installed at one end of the first spiral blade, and a driving block is installed on one side of the cam, and the driving block is movably connected to the movable plate, the cam drives the movable plate to open and close through the driving block, the crushing mechanism comprises a crushing roller, wherein the crushing roller is movably connected to the conveying motor, and the crushing roller plays a role in preliminarily crushing the raw material and slowing down the falling of the raw material.

[0007] By adopting the above technical scheme, the present invention manually puts large quantities of electric carbon raw materials of different sizes into the equipment at one time, and performs preliminary crushing on the mixed raw materials through crushing rollers, avoiding manual pre-screening, significantly improving feeding efficiency and reducing labor costs, and the electric carbon raw materials that are not fully crushed are automatically returned to the crushing area for secondary processing through the conveying mechanism, forming a closed-loop reprocessing. A cam is set in the conveying mechanism to drive the movable plate to open and close at high frequency, which can push the electric carbon raw materials and prevent the raw materials from being blocked. The rotation of the inner cylinder and the outer cylinder cooperates with the multi-stage grinding media to realize deep crushing of the raw materials. At the same time, the impact force of the falling grinding media drives the spring-type screen to vibrate autonomously, and no additional power is required to prevent powder from sticking to the screen holes, thereby ensuring smooth discharge.

[0009] By adopting the above technical solution, the second spiral blade is rotated synchronously with the first spiral blade through the cooperation of the bevel gear set, the sprocket set and the transfer shaft. Under the operation of the second spiral blade, the electric carbon raw material that has not been completely crushed will gradually rise until it reaches the top of the second spiral blade, and then enter the crushing mechanism again through the slide port, so that it can be crushed again. In order to prevent the electric carbon raw material that has not been completely crushed from being blocked in the connecting shell, a cam is installed at the end of the first spiral blade, and a slide is installed in the connecting shell. Therefore, when the cam rotates, the drive block will slide in the slide, and a movable plate is installed at one end of the drive block, and an elastic plate is installed between each two sets of movable plates, and one end of the slide is also connected to the movable plate.

[0010] Furthermore, the crushing mechanism also includes a loading port and a pulley group, wherein the loading port is fixedly installed on the top of the conveying mechanism, and the two sets of crushing rollers are located inside the loading port, and the conveying motor is rotatably connected to the two sets of crushing rollers through the pulley group.

[0011] By adopting the above technical solution, the output shaft of the conveying motor is connected to the two sets of crushing rollers through the pulley set, so the conveying motor drives the crushing rollers to rotate while driving the first spiral blade to rotate.

[0012] Furthermore, the feeding mechanism includes an outer shell, a feeding chamber and a feed chamber, wherein the outer shell is fixedly installed at the bottom of the conveying mechanism, multiple groups of feeding chambers are opened inside the outer shell, and the feeding chambers serve to screen electro-carbon raw materials of the same size, and the bottom of the feeding chamber is connected to the feed chamber, and the bottom of the feed chamber is connected to the inside of the machine body.

[0014] Furthermore, the grinding mechanism includes a grinding motor, a drive shaft, an outer cylinder, an inner cylinder, a planetary gear set and a drive gear, wherein the grinding motor is fixedly installed inside the machine body, the output end of the grinding motor is fixedly connected to the drive shaft, the bottom of the drive shaft is movably connected to the outer cylinder through the drive gear, the top of the drive shaft is movably connected to the inner cylinder through the planetary gear set, the inner cylinder is located inside the outer cylinder, and the inner cylinder and the outer cylinder are rotatably connected; The grinding mechanism also includes a blocking net, a driving plate and a discharge port, wherein the blocking net is fixedly installed at the bottom of the inner cylinder, and multiple groups of grinding media are placed inside the inner cylinder, the driving plate is located between the inner cylinder and the outer cylinder, and the driving plate is fixedly connected to the bottom end of the inner cylinder, and a vibration mechanism located at the bottom end of the outer cylinder is installed at the bottom of the driving plate.

[0015] By adopting the above technical solution, the output end of the grinding motor will drive the drive shaft to rotate, and the drive shaft will drive the inner cylinder to rotate in the opposite direction relative to the outer cylinder through the planetary gear set. Multiple sets of grinding media are placed inside the inner cylinder, and the volume of the electric carbon raw material and the grinding media entering the inner cylinder is larger than the grid in the barrier net at the bottom of the inner cylinder. Therefore, when the inner cylinder rotates, under the action of eccentricity, the grinding media will collide with the electric carbon raw material rapidly. Then, after the electric carbon raw material is crushed, it will pass through the barrier net and enter the area between the outer cylinder and the inner cylinder. Multiple sets of grinding media are also set between the inner cylinder and the outer cylinder. When the inner cylinder rotates, the drive plate will rotate synchronously. Therefore, the electric carbon raw material entering this area will be crushed again, thereby realizing the grinding processing of the electric carbon raw material. In order to prevent the electric carbon raw material ground into powder from clogging the screen, when the grinding mechanism is working, the grinding media will continuously fall on the screen and the connecting shell, thereby continuously squeezing the connecting shell and the screen, and under the action of the spring, the screen will achieve the effect of continuous vibration.

[0016] Furthermore, a pneumatic mechanism is installed on the outside of the bottom end of the second spiral blade, and the pneumatic mechanism includes a connecting pipe and an air pump.

Therefore, a connecting pipe is installed at the bottom of the working area of ​​the second spiral blade, and the connecting pipe is connected to the air pump. Under the operation of the air pump, the smaller electric carbon raw material dust will be transported into the feed chamber.

Under the operation of the second spiral blade 304, the electric carbon raw materials that have not been completely crushed will gradually rise until they reach the top of the second spiral blade 304, and when the driving block 308 slides, the multiple groups of movable plates 310 will be compressed, so that the angle between each two groups of movable plates 310 becomes smaller, and then under the elastic action of the elastic sheet, the movable plates 310 will be subsequently stretched open, thereby realizing the driving of the electric carbon raw materials in the connecting shell 307 and accelerating the passing rate of the electric carbon raw materials in the connecting shell 307; Furthermore, the crushing mechanism 2 includes crushing rollers 202, wherein the crushing rollers 202 are movably connected to the conveying motor 301, and the crushing rollers 202 play the role of preliminary crushing of the raw materials and slowing down the falling of the raw materials. The user can put a large number of electro-carbon raw materials of different sizes into the crushing mechanism 2, and contact them with the crushing rollers 202. The two sets of crushing rollers 202 rotate, and the electro-carbon raw materials will be crushed by the crushing rollers 202 and then fall between the two sets of crushing rollers 202. In addition, due to the presence of the crushing rollers 202, the feeding speed of the electro-carbon raw materials can be slowed down. In the example, the crushing mechanism 2 further includes a loading port 201 and a pulley set 203, wherein the loading port 201 is fixedly mounted on the top of the conveying mechanism 3, and two sets of crushing rollers 202 are located inside the loading port 201, and the conveying motor 301 is rotatably connected to the two sets of crushing rollers 202 via the pulley set 203; The output shaft of the conveying motor 301 is connected to the two sets of crushing rollers 202 through the pulley set 203, so the conveying motor 301 drives the first spiral blade 302 to rotate while also driving the crushing rollers 202 to rotate; In the example, the conveying mechanism 3 also includes a transfer shaft 303, a bevel gear set 311 and a sprocket set 312, wherein the bevel gear set 311 is installed at the end of the first spiral blade 302, and the first spiral blade 302 is movably connected to the transfer shaft 303 through the bevel gear set 311, a sprocket set 312 is installed at the bottom of the transfer shaft 303, and the transfer shaft 303 is movably connected to the second spiral blade 304 through the sprocket set 312, and the conveying mechanism 3 also includes a connecting shell 307 and a slide 309, wherein the connecting shell 307 is installed between the first spiral blade 302 and the second spiral blade 304. The slide 309 is fixedly mounted on one side of the connecting shell 307, and the driving block 308 is slidably connected to the connecting shell 307 through the slide 309. One end of a group of movable plates 310 is rotatably connected to the slide 309. An elastic sheet is installed between each two groups of movable plates 310. The movable plate 310 plays a role in resetting the driving block 308 through the elastic sheet. The conveying mechanism 3 also includes a sliding port 305, wherein the sliding port 305 is fixedly mounted on the top of the second spiral blade 304, and the interior of the sliding port 305 is inclined downward, and the sliding port 305 is connected to the loading port 201; The second spiral blade 304 is rotated synchronously with the first spiral blade 302 through the cooperation of the bevel gear set 311, the sprocket set 312 and the adapter shaft 303. Under the operation of the second spiral blade 304, the electro-carbon raw material that has not been completely crushed will gradually rise until it reaches the top of the second spiral blade 304, and then enter the crushing mechanism 2 again through the sliding port 305, so that it can be crushed again. In order to prevent the incompletely crushed electro-carbon raw materials from being blocked in the connecting shell 307, a cam 306 is installed at the end of the first spiral blade 302, and a slide 309 is installed in the connecting shell 307. Therefore, when the cam 306 rotates, the driving block 308 slides in the slide 309, and a movable plate 310 is installed at one end of the driving block 308. An elastic sheet is installed between each two sets of movable plates 310, and one end of the slide 309 is also connected to the movable plate 310. In the example, the feeding mechanism 4 includes a shell 401, a feeding cavity 402 and a feeding cavity 403, wherein the shell 401 is fixedly mounted on the bottom of the conveying mechanism 3, and multiple groups of feeding cavities 402 are opened inside the shell 401, and the feeding cavity 402 plays the role of screening electro-carbon raw materials of the same size, and the bottom of the feeding cavity 402 is connected to the feeding cavity 403, and the bottom of the feeding cavity 403 is connected to the interior of the body 1; The crushed carbon raw materials will fall to the top of the feeding mechanism 4. The carbon raw materials that meet the size of the feeding cavity 402 will directly slide through the feeding cavity 402 into the feeding cavity 403. The carbon raw materials that are not completely crushed will fall to the top of the feeding mechanism 4. In the example, a pneumatic mechanism 5 is installed on the outside of the bottom end of the second spiral blade 304. The pneumatic mechanism 5 includes a connecting pipe 501 and an air pump 502. One end of the connecting pipe 501 is connected to the working area of ​​the second spiral blade 304, and the other end of the connecting pipe 501 is connected to the air pump 502. The air pump 502 is fixedly installed on the top of the feed chamber 403, and the air outlet end of the air pump 502 is connected to the inside of the feed chamber 403. The air pump 502 plays a role in accelerating the feeding of the electro-carbon raw material; The incompletely crushed electro-carbon raw materials will drop some dust with smaller particles when passing through the conveying mechanism 3. Therefore, a connecting pipe 501 is installed at the bottom of the working area of ​​the second spiral blade 304, and the connecting pipe 501 is connected to the air pump 502. Under the operation of the air pump 502, the smaller electro-carbon raw material dust will be conveyed into the feed chamber 403. At the same time, the air pump 502 supplies air to the inside of the feed chamber 403, which can speed up the rate at which the electro-carbon raw materials pass through the feed chamber 403 and prevent the electro-carbon raw materials of the same size from being blocked in the feed chamber 403. In the example, the grinding mechanism 6 includes a grinding motor 601, a drive shaft 602, an outer cylinder 603, an inner cylinder 604, a planetary gear set 608 and a drive gear 609, wherein the grinding motor 601 is fixedly installed inside the body 1, the output end of the grinding motor 601 is fixedly connected to the drive shaft 602, the bottom of the drive shaft 602 is movably connected to the outer cylinder 603 through the drive gear 609, and the top of the drive shaft 602 is movably connected to the inner cylinder 604 through the planetary gear set 608. The inner cylinder 604 is located inside the outer cylinder 603, and the inner cylinder 604 is rotatably connected to the outer cylinder 603; Furthermore, the grinding mechanism 6 also includes a blocking net 605, a driving plate 606 and a discharge port 607, wherein the blocking net 605 is fixedly mounted on the bottom of the inner cylinder 604, and multiple groups of grinding media are placed inside the inner cylinder 604, the driving plate 606 is located between the inner cylinder 604 and the outer cylinder 603, and the driving plate 606 is fixedly connected to the bottom end of the inner cylinder 604, and the bottom of the driving plate 606 is installed with a vibration mechanism 7 located at the bottom end of the outer cylinder 603, and the discharge port 607 is opened at the bottom of the outer cylinder 603, and the discharge port 607 serves to connect the body 1 with the outside world; Furthermore, the vibration mechanism 7 includes a connecting shell 701, a screen 702 and a spring 703, wherein the connecting shell 701 is movably connected to the bottom end of the inner portion of the outer cylinder 603, the inner portion of the connecting shell 701 is fixedly connected to the screen 702, a spring 703 is installed between the connecting shell 701 and the outer cylinder 603, and the connecting shell 701 and the screen 702 are elastically connected to the outer cylinder 603 via the spring 703; The output end of the grinding motor 601 drives the driving shaft 602 to rotate, and the driving shaft 602 drives the inner cylinder 604 to rotate in the opposite direction relative to the outer cylinder 603 through the planetary gear set 608. A plurality of grinding media are placed inside the inner cylinder 604. The volume of the electro-carbon raw material and the grinding media entering the inner cylinder is larger than the grid in the blocking net 605 at the bottom of the inner cylinder 604. Therefore, when the inner cylinder 604 rotates, under the action of the centrifugal force, the grinding media will quickly collide with the electro-carbon raw material. Then, after the electro-carbon raw material is crushed, it will pass through the blocking net 605 and enter the space between the outer cylinder 603 and the inner cylinder 604. In the area, multiple groups of grinding media are also arranged between the inner cylinder 604 and the outer cylinder 603. When the inner cylinder 604 rotates, the driving plate 606 will rotate synchronously. Therefore, the electric carbon raw materials entering this area will be crushed again, thereby realizing the grinding processing of the electric carbon raw materials. In order to prevent the electric carbon raw materials ground into powder from clogging the screen 702, when the grinding mechanism 6 is working, the grinding media will continuously fall on the screen 702 and the connecting shell 701, thereby continuously squeezing the connecting shell 701 and the screen 702, and under the action of the spring 703, the screen 702 will achieve the effect of continuous vibration.

[0024] The working principle of the present invention is as follows: when the power is turned on, the user can first put a large number of carbon raw materials of different sizes into the feeding port 201. The carbon raw materials enter the crushing mechanism 2 and first come into contact with the crushing rollers 202. The two sets of crushing rollers 202 rotate in opposite directions, so the carbon raw materials are crushed by the crushing rollers 202 and then fall between the two sets of crushing rollers 202. In addition, the presence of the crushing rollers 202 can slow down the feeding speed of the carbon raw materials. The crushed carbon raw materials will fall to the top of the feeding mechanism 4, among which the carbon raw materials that meet the size of the feeding cavity 402 will directly slide through the feeding cavity 402 and fall into the feeding cavity 403. Since a large number of carbon raw materials of different sizes are put into the crushing mechanism 2 together, in order to ensure that the crushing mechanism 2 can discharge the materials quickly, there is a certain gap between the two sets of crushing rollers 202. Therefore, some carbon raw materials that are not completely crushed will also fall to the top of the feeding mechanism 4. The output end of the conveying motor 301 is connected to the first spiral blade 302, so it drives the first spiral blade 302 to rotate. At the same time, the output shaft of the conveying motor 301 is connected to the two sets of crushing rollers 202 through the pulley set 203. Therefore, when the conveying motor 301 drives the first spiral blade 302 to rotate, it also drives the crushing rollers 202 to rotate. The incompletely crushed electro-carbon raw material will move forward under the operation of the first spiral blade 302 until it reaches the connecting shell 307. The incompletely crushed electro-carbon raw material will enter the working area of ​​the second spiral blade 304 through the connecting shell 307. The second spiral blade 304 is synchronously rotated by the first spiral blade 302 through the cooperation of the bevel gear set 311, the sprocket set 312 and the adapter shaft 303. Therefore, under the operation of the second spiral blade 304, the incompletely crushed electro-carbon raw material will gradually rise until it reaches the top of the second spiral blade 304, and then enter the crushing mechanism 2 again through the sliding port 305, so that it can be crushed again. In order to prevent the incompletely crushed electro-carbon raw materials from being blocked in the connecting shell 307, a cam 306 is installed at the end of the first spiral blade 302, and a slide 309 is installed in the connecting shell 307. Therefore, when the cam 306 rotates, the driving block 308 slides in the slide 309, and a movable plate 310 is installed at one end of the driving block 308, and an elastic sheet is installed between each two sets of movable plates 310, and one end of the slide 309 is also connected to the movable plate 310; Therefore, when the driving block 308 slides, the multiple groups of movable plates 310 will be compressed, so that the angle between each two groups of movable plates 310 becomes smaller. Then, under the elastic action of the elastic sheet, the movable plates 310 will be subsequently stretched open, so that the driving block 308 will slide in the slide 309. Under the cooperation of the cam 306 and the movable plates 310, the driving block 308 will reciprocate in the slide 309, so that the movable plates 310 are continuously squeezed and stretched open, thereby realizing the driving of the electro-carbon raw material in the connecting shell 307 and accelerating the passing rate of the electro-carbon raw material in the connecting shell 307. The incompletely crushed electric carbon raw materials will drop some small dust particles when passing through the conveying mechanism 3. Therefore, a connecting pipe 501 is installed at the bottom of the working area of ​​the second spiral blade 304, and the connecting pipe 501 is connected to the air pump 502. Under the operation of the air pump 502, the smaller electric carbon raw material dust will be transported into the feed chamber 403. At the same time, the air pump 502 supplies air to the inside of the feed chamber 403, which can speed up the rate at which the electric carbon raw materials pass through the feed chamber 403 and prevent the electric carbon raw materials of the same size from being blocked in the feed chamber 403. After the carbon raw materials of approximately the same size enter the machine body 1, they will directly enter the grinding mechanism 6. Under the operation of the grinding motor 601, the output end of the grinding motor 601 will drive the drive shaft 602 to rotate. The bottom of the outer cylinder 603 is equipped with teeth, and the bottom of the drive shaft 602 is equipped with a drive gear 609. Therefore, when the drive gear 609 is driven by the drive shaft 602 to rotate, it will drive the outer cylinder 603 to rotate synchronously. Gears are installed on the top of the inner cylinder 604, and a planetary gear set 608 is installed on the top of the drive shaft 602. The drive shaft 602 drives the inner cylinder 604 to rotate in the opposite direction relative to the outer cylinder 603 through the planetary gear set 608. Multiple sets of grinding media are placed inside the inner cylinder 604. The volume of the electro-carbon raw material and the grinding media entering the inner cylinder is larger than the grid inside the blocking net 605 at the bottom of the inner cylinder 604. Therefore, when the inner cylinder 604 rotates, the grinding media will quickly collide with the electro-carbon raw material under the action of eccentricity. Then, after the electro-carbon raw material is crushed, it will pass through the blocking net 605 and enter the area between the outer cylinder 603 and the inner cylinder 604. Multiple sets of grinding media are also set between the inner cylinder 604 and the outer cylinder 603, and a driving plate 606 is installed at the bottom of the inner cylinder 604. When the inner cylinder 604 rotates, the driving plate 606 will rotate synchronously. Therefore, the electro-carbon raw materials entering this area will be crushed again, thereby achieving the grinding process of the electro-carbon raw materials; In order to prevent the electric carbon raw material ground into powder from clogging the screen 702, when the grinding mechanism 6 is working, the vibration mechanism 7 is installed at the inner bottom end of the outer cylinder 603, and the grinding medium will continuously fall on the screen 702 and the connecting shell 701 when it is driven to move between the inner cylinder 604 and the outer cylinder 603. Between the bottom of the connecting shell 701 and the outer cylinder 603, multiple sets of springs 703 are installed. Therefore, the continuously falling grinding medium will continuously squeeze the connecting shell 701 and the screen 702, and under the action of the springs 703, the screen 702 will achieve the effect of continuous vibration, so that the ground electric carbon raw material can pass through the screen 702 and fall to the outside of the body 1 from the discharge port 607. A collecting mechanism is placed in advance at the bottom of the body 1 to collect the ground electric carbon raw material. The above structure can solve the technical problems that manual loading and unloading of materials during grinding is required, and manual loading of large quantities of raw materials at one time may cause blockage inside the equipment, and raw materials of different sizes cannot be fully ground inside the equipment.
