Description

Technical Field

[0001] This utility model relates to the field of pulverizers, and in particular to a separation and screening device for an ultrafine pulverizer. Background Technology

[0002] A shredder is a device used to crush or cut items or materials into small particles or powder. This equipment is commonly used to process different types of raw materials such as waste, plastics, metals, and food. Shredders have various uses in both industrial and domestic environments, helping people process materials, reduce volume, or fulfill other processing needs.

[0003] While existing technologies can achieve some material screening, they suffer from the following drawback: the existing crushing devices lack efficient material screening capabilities, resulting in the inability to quickly crush materials and leaving a large number of large particles that affect subsequent fine particle size reduction. In view of this, we propose a separation and screening device for ultrafine crushers, which solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a separation and screening device for an ultrafine pulverizer.

[0005] The technical solution of this utility model is as follows: A separation and screening device for an ultrafine pulverizer includes a mounting frame, a screen cylinder, a cutter, a first screen plate, and a second screen plate. Insert rods are inserted into both sides of the mounting frame. A screen cylinder is fixed to the lower end of each insert rod. A first screen plate is fixed to the lower end of the screen cylinder. A second screen plate is rotatably mounted to the lower end of the first screen plate. A cutter is rotatably mounted to the lower end of the mounting frame. A cam is rotatably mounted to the upper end of the mounting frame. The cam is in contact with the upper end of each insert rod. A gear is rotatably mounted on one outer wall of the first screen plate. A rack is provided on the outer wall of the second screen plate, and the gear meshes with the rack.

[0006] When using this device, the material can be poured in from the top of the mounting frame and enters the screen cylinder. Driven by the rotating motor, the cutter will cut the material. As the size of the material decreases, the smaller material will be discharged from the outer wall of the screen cylinder and the through holes of screen plate one and screen plate two. The discharged material is small in size. The material that is not discharged can continue to participate in the cutting inside until it is separated and passes through the through holes. When some stubborn materials cannot be further refined, the servo motor can be used to drive screen plate two to rotate relative to screen plate one. The through holes generated by screen plate one and screen plate two are mainly formed by the interlacing of the independently designed through holes. When screen plate two rotates at a certain angle, the gear of the through hole will become larger, which can screen out large stubborn particles. This can quickly empty the material inside the screen cylinder without affecting the original screening effect of particle size, ensuring the orderly progress of screening. When the cutter cuts the material, the screen cylinder will move up and down under the action of the cam, which can achieve fine crushing of the material.

[0007] Preferably, a fixing frame is fixed to the upper end of the mounting bracket, the cam is rotatably mounted between the fixing frames, and a second spring is fixed between the cap of the insertion rod and the mounting bracket. When the top of the cam is directly above, the second spring is in a compressed state.

[0008] Preferably, a second rotating motor is fixed to one side of the outer wall of the fixed frame, the output shaft of the second rotating motor is fixedly connected to the rotation center on one side of the cam, and a synchronizer is fixed to one side of the outer wall of the fixed frame, the synchronizer being adapted to the second rotating motor.

[0009] Preferably, the mounting frame is fixed with brackets on both sides, and a base is fixed at the lower end of the brackets, with the lower surface of the base being 30 centimeters lower than the lower surface of the sieve plate.

[0010] Preferably, a mounting base is fixed to one outer wall of the sieve disc, the gear is rotatably mounted inside the mounting base, a servo motor is fixed to one outer wall of the mounting base, and the output shaft of the servo motor is fixedly connected to the rotation center of one side of the gear.

[0011] Preferably, a rotating shaft is rotatably mounted on the lower end of the mounting plate, and a cutting blade with a four-layer design is fixedly mounted on the lower end of the rotating shaft. A rotating motor is fixedly mounted on the upper end of the mounting plate, and the output shaft of the rotating motor is fixedly connected to the rotating shaft.

[0012] Preferably, a fitting groove is provided in the middle of the upper surface of the screen plate, which can cooperate with the limiting key and the limiting plate when the screen cylinder moves down.

[0013] Preferably, a turntable is rotatably mounted on the lower end of the cutter, a telescopic column is fixed to the lower end of the turntable, a telescopic rod is inserted into the lower end of the telescopic column, a limit plate is fixed to the lower end of the telescopic rod, a limit key is provided at the lower end of the limit plate, and the limit key is inserted into the fitting groove.

[0014] Preferably, a spring is fixed between the limiting plate and the lower end of the cutter, and the spring is located on the outer wall of the telescopic column and the telescopic rod.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model can utilize the up-and-down movement of the sieve cylinder driven by a cam, combined with a cutter in a fixed position, to achieve an alternating crushing and cutting effect, resulting in a high rate of material refinement and stable operation.

[0017] Second, based on the first beneficial effect, by utilizing the rotation effect between screen disc one and screen disc two, the screening size after the two are combined can be changed, thereby assisting in the discharge of large and stubborn particles inside the screen cylinder.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figures 1-6 As shown, this embodiment is a separation and screening device for an ultrafine pulverizer, including a mounting frame 1, a screen cylinder 4, a cutter 11, a first screen plate 5 and a second screen plate 12. Insert rods 3 are inserted into both sides of the mounting frame 1. The screen cylinder 4 is fixed to the lower end of the insert rods 3. The first screen plate 5 is fixed to the lower end of the screen cylinder 4. The second screen plate 12 is rotatably installed at the lower end of the first screen plate 5. The cutter 11 is rotatably installed inside the lower end of the mounting frame 1. The cam 14 is rotatably installed at the upper end of the mounting frame 1. The cam 14 is in contact with the upper end of the insert rods 3. A gear 26 is rotatably installed on one side of the outer wall of the first screen plate 5. A rack 13 is provided on the outer wall of the second screen plate 12. The gear 26 meshes with the rack 13.

[0033] When using this device, the material can be poured in from the top of the mounting frame 1 and enter the screen cylinder 4. Driven by the rotating motor 10, the cutter 11 will cut the material. As the size of the material decreases, the smaller material will be discharged from the outer wall of the screen cylinder 4 and the through holes of the screen plate 1 and screen plate 2 12. The discharged material is small in size. The material that is not discharged can continue to participate in the cutting inside until it is separated and passes through the through hole. When some stubborn material cannot be further refined, the servo motor 19 can be used to drive the screen plate 2 12 to rotate relative to the screen plate 1 5. The through holes generated by the screen plate 1 5 and the screen plate 2 12 are mainly formed by the interlacing of the independently designed through holes. When the screen plate 2 12 rotates at a certain angle, the gear 26 of the through hole will become larger, which can screen out large stubborn particles. This can quickly empty the material inside the screen cylinder 4 without affecting the original screening effect of particle size, ensuring the orderly progress of screening. When the cutter 11 cuts the material, the screen cylinder 4 will move up and down under the action of the cam 14, which can realize the fine crushing of the material.

[0034] Example 2

[0035] Please see Figures 1-6 As shown, this embodiment, based on embodiment 1, further includes: a fixed frame 17 fixed to the upper end of the mounting frame 1, a cam 14 rotatably mounted between the fixed frames 17, and a spring 18 fixed between the cap of the insert rod 3 and the mounting frame 1. When the top of the cam 14 is directly above, the spring 18 is in a compressed state. Under the action of the spring 18, when the top of the cam 14 reaches the top, the spring 18 can drive the insert rod 3 to move the screen cylinder 4 upward. Then, when the top of the cam 14 reaches the bottom, the screen cylinder 4 will move downward. This reciprocating motion can optimize the particle refining effect of the cutter 11 and can also perform a certain amount of shaking to facilitate the screening of qualified fine particles.

[0036] A rotating motor 15 is fixed to one side of the outer wall of the fixed frame 17. The output shaft of the rotating motor 15 is fixedly connected to the rotation center of one side of the cam 14. A synchronizer 16 is fixed to one side of the outer wall of the fixed frame 17. The synchronizer 16 is adapted to the rotating motor 15. The rotating motor 15 can drive the cam 14 to rotate continuously in one direction. The cam 14 is a flexible collision, which can realize the effect of the screen cylinder 4 moving up and down.

[0037] Mounting frame 1 has brackets 2 fixed on both sides, and a base 6 fixed at the lower end of the brackets 2. The lower surface of the base 6 is 30 centimeters lower than the lower surface of the screen plate 12. The brackets 2 and the base 6 can increase the stability of the device and reduce the transmission of noise to a certain extent.

[0038] A mounting base 27 is fixed to the outer wall of screen plate 5. Gear 26 is rotatably mounted inside the mounting base 27. A servo motor 19 is fixed to one side of the outer wall of the mounting base 27. The output shaft of the servo motor 19 is fixedly connected to the rotation center of one side of the gear 26. The servo motor 19 can drive the gear 26 to rotate a short distance, so that the through holes between screen plate 5 and screen plate 12 do not overlap, increasing the size of the through holes after merging, which facilitates the discharge of stubborn particulate matter such as relatively hard minerals.

[0039] A rotating shaft 8 is rotatably mounted on the lower end of the mounting plate 9. A four-layer cutter 11 is fixedly mounted on the lower end of the rotating shaft 8. A rotating motor 10 is fixedly mounted on the upper end of the mounting plate 9. The output shaft of the rotating motor 10 is fixedly connected to the rotating shaft 8. The rotating motor 10 can drive the cutter 11 to rotate continuously, thereby achieving the fine processing of materials.

[0040] A fitting groove 7 is provided in the middle of the upper surface of the screen plate 5. When the screen cylinder 4 moves down, the fitting groove 7 can cooperate with the limit key 25 and the limit plate 24 to ensure that the central shaft coincides with the screen plate 5, which can stabilize the high-speed rotation effect of the cutter 11 to a certain extent.

[0041] A turntable 20 is rotatably mounted on the lower end of the cutter 11. A telescopic column 23 is fixed to the lower end of the turntable 20. A telescopic rod 22 is inserted into the lower end of the telescopic column 23. A limit plate 24 is fixed to the lower end of the telescopic rod 22. A limit key 25 is provided at the lower end of the limit plate 24 and is inserted into the fitting groove 7. A spring 21 is fixed between the limit plate 24 and the lower end of the cutter 11. The spring 21 is located on the outer wall of the telescopic column 23 and the telescopic rod 22. The spring 21 can ensure the continuous cooperation between the limit key 25 and the fitting groove 7, preventing them from separating and ensuring that the cutter 11 can rotate stably at high speed.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
