Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder processing, in particular to a crushing and impurity removing machine for carbon powder processing. Background Art

[0002] Carbon powder is a fine granular substance made of carbon. It usually has the characteristics of high purity, small particle size and uniform particle distribution. In order to improve product quality and production efficiency and ensure the purity of raw materials, carbon powder usually needs to be crushed and impurities separated.

[0003] The Chinese patent "A crushing and impurity removal machine for carbon powder production" authorization announcement number "CN219765465U" can screen out some completely crushed carbon powder through the blower on the right side of the first screen in the screening mechanism, and start the vibration device installed on the front surface of the side plate, so that some completely crushed carbon powder can be screened out, and the incompletely crushed carbon powder and some debris can slide into the crushing roller. The first motor works to drive the first rotating shaft to rotate, so that the crushing roller operates to crush the carbon powder, so that the carbon powder is completely crushed, and the completely crushed carbon powder falls into the second screen. The vibration motor on the right side of the second screen works to drive the second screen to screen, so that some substances that are not easy to crush and do not belong to carbon powder are separated.

[0004] Since the raw materials of carbon powder contain iron substances, such as iron ore and iron powder, although the large iron particles that are difficult to crush can be screened out in the above case, when the carbon powder raw materials are crushed, some iron substances will be crushed into small particles and mixed in the carbon powder, which are difficult to be screened out, thus affecting the quality of the carbon powder after screening.

[0005] Therefore, a pulverizing and impurity removing machine for carbon powder processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a crushing and impurity removing machine for carbon powder processing in order to solve the above-mentioned problem, thereby improving the problem that when the carbon powder raw material is crushed, some iron substances will be crushed into small particles and mixed in the carbon powder, which is difficult to be screened out, thereby affecting the quality of the carbon powder after screening.

The impurity removal component is set up, and the second electromagnet will perform the second adsorption of small particles of iron in the crushed carbon powder raw material. Moreover, under the action of the weight of the carbon powder, it is beneficial for the bottom end of the rotating plate to expand outward to better contact the carbon powder, thereby improving the adsorption effect of the second electromagnet. Under the action of the reciprocating vibration of the first spring and the first screen plate, it is beneficial for the rotating plate to drive the second electromagnet to swing back and forth while adsorbing the small particles of iron, and to stir the carbon powder, which is beneficial for the second electromagnet to adsorb the small particles of iron in the carbon powder more thoroughly, thereby improving the quality of the carbon powder after screening.

[0009] Preferably, the top of the guide plate is fixedly connected with a convex block distributed in a rectangular array, and the convex block is in the shape of a cone.

DETAILED DESCRIPTION

[0024] 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.

[0025] When implementing: Figure 1-5As shown, a pulverizing and impurity removing machine for carbon powder processing comprises: a processing box 1, wherein the upper end of the inner wall of the processing box 1 is rotatably connected to two first grinding rollers 2, and the lower end of the inner wall of the processing box 1 is rotatably connected to two second grinding rollers 3; an impurity removing mechanism 4, which is used to remove small-particle iron substances and is arranged inside the processing box 1; wherein the impurity removing mechanism 4 comprises a first sieve plate 401 slidably connected to the middle part of the inner wall of the processing box 1, the first sieve plate 401 is inclinedly arranged, the bottom end of the first sieve plate 401 is fixedly connected to the second sieve plate 402, the top end of the first sieve plate 401 is fixedly connected to a guide plate 403, the inner wall of the guide plate 403 is embedded with a first electromagnet 404, one side of the processing box 1 is fixedly connected to a first motor 405, the output shaft of the first motor 405 passes through the interior of the processing box 1 and is fixedly connected to a cam 406, the bottom end of the first sieve plate 401 is in contact with the surface of the cam 406, and the top of the first sieve plate 401 is provided with an impurity removing component 407. The top of the guide plate 403 is fixedly connected with protrusions 408 distributed in a rectangular array, and the protrusions 408 are in the shape of a cone. The angle between the guide plate 403 and the horizontal plane is less than 45 degrees, and the guide plate 403 and the first screen plate 401 are in a horizontal "eight" shape as a whole.

[0026] When the toner raw material is crushed, the cover of the feed port at the top of the processing box 1 is opened, and the toner raw material is poured in. A second motor is fixedly connected to the upper end of one side of the processing box 1, and one end of the two first grinding rollers 2 passes through the processing box 1 and is fixedly connected to the first gear. The two first gears are meshed with each other, and one of the first gears is fixedly connected to the output shaft of the second motor. After the raw material is poured in, the second motor is started to drive the first grinding roller 2 to rotate to grind the raw material. The crushed toner will fall onto the guide plate 403, and the first electromagnet 404 is started to adsorb the small particles of iron in the crushed toner raw material, and it will fall onto the first sieve plate 401 through the guide plate 403. At this time, the first motor 405 is started to drive the cam 406 to rotate, and the first sieve plate 401 is rotated between the cam 406 and Under the action of the weight of the carbon powder raw material, it will move up and down reciprocatingly to screen the crushed carbon powder, thereby driving the second screen plate 402 and the guide plate 403 to move up and down synchronously. The first screen plate 401 operates while the impurity removal component 407 is screening. The second grinding roller 3 is arranged below the lower end of the first screen plate 401. The operating principle of the two second grinding rollers 3 is the same as that of the two first grinding rollers 2. After the crushed carbon powder passes through the first screen plate 401 for screening, some larger substances will slide between the two second grinding rollers 3 under the action of the inclined surface of the first screen plate 401. At this time, the second grinding roller 3 is driven to rotate to crush the larger substances again. The carbon powder screened by the first screen plate 401 and crushed again will fall onto the second screen plate 402 for secondary screening.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the impurity removal assembly 407 includes a plurality of round rods 4072, which are distributed in a rectangular array at the top of the first sieve plate 401, the surface of the round rods 4072 is slidably connected to the cylinder 4071, the top of the round rods 4072 is fixedly connected to the first spring 4073, the top of the first spring 4073 is fixedly connected to the inner top wall of the cylinder 4071, two rotating plates 4074 are hinged on the upper end of the surface of the cylinder 4071, the lower end of the surface of the round rods 4072 is hinged to a connecting rod 4075, the other end of the connecting rod 4075 is hinged to one side of the rotating plate 4074, and the inner wall of the rotating plate 4074 is embedded with a second electromagnet 4076. The rotating plate 4074 is a quarter ring, the center of the rotating plate 4074 is the same as the center of the cylinder 4071, and the two rotating plates 4074 are symmetrical with the center of the cylinder 4071. The top end of the cylinder 4071 is in the shape of a flat-topped cone.

[0028] When the guide plate 403 guides the crushed carbon powder to the first sieve plate 401, the second electromagnet 4076 is started. When the carbon powder falls on the first sieve plate 401, the second electromagnet 4076 will perform secondary adsorption on the small particles of iron in the crushed carbon powder raw material. At the same time, under the action of the carbon powder's own weight, it will exert downward pressure on the cylinder 4071. At this time, the cylinder 4071 will move downward and squeeze the first spring 4073. When the cylinder 4071 moves downward, it will drive the top of the rotating plate 4074 to move downward. At this time, under the action of the connecting rod 4075, the angle between the rotating plate 4074 and the cylinder 4071 gradually increases, so that the rotating plate The bottom end of 4074 is extended outward to better contact with the carbon powder, thereby improving the adsorption effect of the second electromagnet 4076. At the same time, under the action of the vibration of the first sieve plate 401, the cylinder 4071 will throw out the pressed raw material. At this time, the cylinder 4071 is reset under the action of the first spring 4073, thereby driving the rotating plate 4074 to reset. Therefore, the rotating plate 4074 will swing back and forth under the action of the first spring 4073 and the weight of the carbon powder, so that the rotating plate 4074 drives the second electromagnet 4076 to adsorb small particles of iron materials while moving the carbon powder, which is beneficial for the second electromagnet 4076 to adsorb small particles of iron materials in the carbon powder more thoroughly.

[0029] like Figure 3As shown, both sides of the first sieve plate 401 are fixedly connected with sliders 409, the surface of the sliders 409 is slidably connected to the inner wall of the processing box 1, the bottom end of the sliders 409 is fixedly connected with a second spring 4091, and the other end of the second spring 4091 is fixedly connected to the inner wall of the processing box 1. Both sides of the top of the first sieve plate 401 are fixedly connected with protective plates 4092, and one side of the protective plate 4092 is in contact with the inner wall of the processing box 1. Both sides of the inner wall of the processing box 1 are provided with slide grooves that match the sliders 409. When the first sieve plate 401 moves up and down, the sliders 409 move in the slide grooves, and the width of the protective plate 4092 matches the width of the slide grooves and the protective plate 4092 is arranged on one side of the slide grooves.

[0030] When the utility model is used, when the carbon powder raw material is crushed, the pigment is poured into the processing box 1, the first grinding roller 2 is started to grind the carbon powder raw material, and the first motor 405 is started to drive the first screen plate 401 to drive the second screen plate 402 and the guide plate 403 to move up and down synchronously, and the crushed carbon powder will slide onto the first screen plate 401 through the guide plate 403. During this process, the first electromagnet 404 is started to absorb the small particles of iron in the crushed carbon powder raw material for the first time. At this time, when the carbon powder slides onto the first screen plate 401, the second electromagnet 4076 is started to absorb the small particles of iron in the crushed carbon powder raw material for the second time. The carbon powder is adsorbed again. At the same time, under the action of the carbon powder's own weight, the cylinder 4071 will drive the top of the rotating plate 4074 to move downward and squeeze the first spring 4073. Under the action of the connecting rod 4075, the bottom end of the rotating plate 4074 will expand outward to better contact the carbon powder. The first sieve plate 401 will vibrate back and forth up and down. The cylinder 4071 will throw out the pressed raw material and drive the rotating plate 4074 to reset under the action of the first spring 4073. The rotating plate 4074 drives the second electromagnet 4076 to swing back and forth while adsorbing small particles of iron material, and stirs the carbon powder, which is beneficial to more thorough adsorption of small particles of iron material in the carbon powder.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
