Description

Technical Field

[0001] This utility model relates to the field of lubricant processing technology, and more specifically, to a device for pulverizing solid lubricants to ensure thorough pulverization. Background Technology

[0002] Solid lubricants are a class of materials that reduce friction and wear between friction pairs in a solid state, and are widely used in various mechanical systems. Pulverization is a key step in the processing of solid lubricants. Pulverization can significantly improve the specific surface area, dispersibility, chemical stability, and activity of the lubricant, thereby better meeting the needs of different application scenarios and improving its performance and lifespan in actual use.

[0003] Patent CN221868708U discloses a pulverizing device for solid lubricants. When the drive shaft rotates, it drives the pulverizing shaft to rotate together, and the pulverizing blades on the pulverizing shaft rotate together to pulverize the material in the pulverizing barrel.

[0004] Although the aforementioned pulverizing equipment can pulverize solid lubricants using the rotation of the pulverizing cutter, the pulverization of solid lubricants is completed within a vertically positioned pulverizing drum. During the pulverization process, a large amount of solid lubricant accumulates at the bottom of the pulverizing drum under gravity, making it difficult for the cutter to make sufficient contact with the solid lubricant. This results in incomplete pulverization, ultimately producing finished particles with uneven particle size, which affects the lubrication effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a solid lubricant pulverizing device that employs a multi-stage pulverization method, first pre-pulverizing the solid lubricant, then further pulverizing it, and finally sieving and filtering the pulverized solid lubricant to ensure thorough pulverization and uniform particle size of the finished product.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A solid lubricant pulverizing device for thorough pulverization includes a mounting bracket, a pre-pulverizing component and a pulverizing component mounted on the mounting bracket, and a scraping component and a baffle component mounted on the pulverizing component. The pulverizing component includes a pulverizing cylinder inclined along a horizontal plane, a third pulverizing shaft rotatably disposed within the pulverizing cylinder, and a pulverizing cutter disposed around the third pulverizing shaft. The scraping component includes a plurality of mounting rods equidistantly arranged along the axial direction of the third pulverizing shaft, each mounting rod being connected to a scraper plate, the scraper plate being in contact with the inner wall of the pulverizing cylinder.

[0008] The present invention is further configured such that: the pre-crushing component includes a first crushing shaft and a second crushing shaft that mesh with each other, a pre-crushing cutter disposed on the first crushing shaft and the second crushing shaft, and a feeding hopper that communicates with the crushing component.

[0009] The present invention is further configured such that: the pre-crushing motor and the second crushing shaft are arranged in the feeding hopper, one end of the first crushing shaft is connected to the pre-crushing motor, and the bottom of the feeding hopper is connected to the unloading hopper.

[0010] The present invention is further configured such that: the pre-crushing cutter is arranged axially along the first crushing shaft and the second crushing shaft, and the pre-crushing cutter on the first crushing shaft and the pre-crushing cutter on the second crushing shaft are arranged at equal intervals.

[0011] The present invention is further configured such that: a vibration motor is connected to the side wall of the crushing cylinder, the two ends of the third crushing shaft pass through the crushing cylinder, one end of the third crushing shaft is connected to the crushing motor, and several filter holes are opened at the bottom of the crushing cylinder.

[0012] The present invention is further configured such that: the crushing cutter is arranged around the axis of the third crushing shaft, the two crushing cutters are equidistant from each other, and the length of the crushing cutter is less than the inner diameter of the crushing cylinder.

[0013] By adopting the above technical solution, as the mounting rod rotates with the third crushing shaft, the scraper plate comes into contact with the inner wall of the crushing cylinder, thereby scraping off the solid lubricant adhering to the inner wall of the crushing cylinder, allowing it to be crushed again, and further improving the crushing uniformity.

[0014] The present invention is further configured such that: the material blocking assembly includes a material blocking arc plate that fits against the outer wall of the crushing cylinder and a sliding groove installed on both sides of the crushing cylinder, and a plurality of pulleys that can slide on the sliding groove are connected to the material blocking arc plate.

[0015] The beneficial effects of this utility model are:

[0016] First, the solid lubricant is pre-crushed by the rotation of the first and second crushing shafts using a pre-crushing cutter to reduce its fineness. Then, the rotation of the third crushing shaft drives the crushing cutter to further crush the solid lubricant in the crushing cylinder. This multi-stage crushing method improves the thoroughness of crushing and thus enhances the particle size uniformity of the solid lubricant. Simultaneously, the scraper 43, in conjunction with the crushing cutter 34, effectively disperses the solid lubricant in the crushing cylinder 31, increasing its dispersion and preventing accumulation that could hinder the thorough crushing process.

[0030] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Please refer to Figures 1-3 A solid lubricant pulverizing device for thorough pulverization includes a mounting bracket 1, a pre-pulverizing component 2 and a pulverizing component 3 mounted on the mounting bracket 1, and a scraper component 4 and a baffle component 5 mounted on the pulverizing component 3. The solid lubricant is first pulverized by the pre-pulverizing component 2, and after pre-pulverization, it enters the pulverizing component 3 for secondary pulverization. After secondary pulverization, the baffle component 5 opens, and with the cooperation of the scraper component 4, the solid lubricant is filtered and discharged from the pulverizing component 3.

[0032] Please refer to Figures 1-3 The mounting bracket 1 includes a first bracket 11 and a second bracket 12 and a third bracket 13 arranged along the axis of the crushing component 3. The third bracket 13 is located on the side of the second bracket 12 away from the first bracket 11. The crushing component 3 is mounted on the first bracket 11, and the pre-crushing component 2 is mounted on the second bracket 12 and the third bracket 13.

[0033] Please refer to Figures 1-3 and Figure 5The pre-crushing component 2 includes a first crushing shaft 23 and a second crushing shaft 24 that mesh with each other, a pre-crushing cutter 25 disposed on the first crushing shaft 23 and the second crushing shaft 24, and a feeding bin 26 communicating with the crushing component 3. A pre-crushing motor 22 and a second crushing shaft 24 are disposed within a feeding bin 21, and the pre-crushing motor 22 and the second crushing shaft 24 can rotate relative to the feeding bin 21. The feeding bin 21 is mounted on top of the second support 12. An opening is provided at the top of the feeding bin 21, through which solid lubricant can enter the feeding bin 21 for pre-crushing processing. During the pre-crushing process, a baffle can be added to the opening at the top of the feeding bin 21 to prevent solid lubricant powder from splashing during crushing. One end of the first crushing shaft 23 is connected to the pre-crushing motor 22, which is mounted on top of the third support 13, and the pre-crushing motor 22 can drive the first crushing shaft 23 to rotate. The pre-crushing cutter 25 is axially arranged along the first crushing shaft 23 and the second crushing shaft 24, with the pre-crushing cutters 25 on the first crushing shaft 23 and the second crushing shaft 24 being equidistantly spaced. The pre-crushing motor 22 and the ends of the second crushing shaft 24 are equipped with meshing gears, both located outside the feed hopper 21. During the rotation of the first crushing shaft 23, the meshing of the gears synchronously drives the second crushing shaft 24 to rotate. As the first and second crushing shafts rotate, the synchronous rotation of the pre-crushing cutter 25 pre-crushes the solid lubricant, reducing its fineness for subsequent secondary crushing. The bottom of the feed hopper 21 is connected to the discharge hopper 26. The pre-crushed solid lubricant flows downwards into the discharge hopper 26 and finally into the crushing assembly 3.

[0034] Please refer to Figures 1-4The crushing assembly 3 includes a crushing cylinder 31 inclined along a horizontal plane, a third crushing shaft 32 rotatably disposed within the crushing cylinder 31, and crushing cutters 34 arranged around the third crushing shaft 32. The crushing cylinder 31 is a hollow cylindrical structure, and the side of the crushing cylinder 31 near the feeding bin 26 is connected to the feeding bin 26. The feeding bin 26 is connected inside the crushing cylinder 31, and the solid lubricant in the feeding bin 26 can enter the crushing cylinder 31 for secondary crushing. The third crushing shaft 32 extends through the crushing cylinder 31 at both ends, and the two ends of the third crushing shaft 32 are rotatably mounted on the first bracket 11. A crushing motor 33 is connected to one end of the third crushing shaft 32. The crushing motor 33 is installed in the middle of the second bracket 12, and the crushing motor 33 is located below the feeding bin 26. The crushing motor 33 can drive the third crushing shaft 32 to rotate. The crushing cutters 34 are arranged around the axis of the third crushing shaft 32, and the two crushing cutters 34 are equidistant from each other. The length of the crushing cutters 34 is less than the inner diameter of the crushing cylinder 31. During the rotation of the third crushing shaft 32, the crushing cutter 34 can be driven to rotate synchronously, further crushing the solid lubricant in the crushing cylinder 31. The crushing cylinder 31 is inclined along the horizontal plane, specifically, the inclination angle between the crushing cylinder 31 and the horizontal plane is set to 5-10°, and the lower end of the crushing cylinder 31 is located on the side away from the pre-crushing component 2. Several filter holes 35 are opened at the bottom of the crushing cylinder 31. After the secondary crushing is completed, the solid lubricant is filtered through the filter holes 35 and discharged from the filter holes 35 to complete the feeding. During feeding, a hopper for receiving solid lubricant can be set at the bottom of the crushing cylinder 31 to facilitate the direct collection of solid lubricant after discharge. A vibration motor 36 is connected to the side wall of the crushing cylinder 31. During the solid lubricant feeding process, the operation of the vibration motor 36 can drive the crushing cylinder 31 to vibrate, facilitating the discharge of solid lubricant from the filter holes 35.

[0035] Please refer to Figures 3-4 The scraping assembly 4 includes multiple mounting rods 41 equidistantly arranged along the axial direction of the third crushing shaft 32, which surround the third crushing shaft 32. The mounting rods 41 are connected to the third crushing shaft 32 and installed between the crushing cutters 34, ensuring that the crushing cutters 34 can complete the crushing process normally while simultaneously rotating with the third crushing shaft 32. Each mounting rod 41 has a fitting groove 42 at its end away from the third crushing shaft 32, and a scraper plate 43 is connected to each mounting rod 41, installed inside the fitting groove 42. The scraper plate 43 is in contact with the inner wall of the crushing cylinder 31. As the mounting rods 41 rotate with the third crushing shaft 32, the scraper plate 43 remains in contact with the inner wall of the crushing cylinder 31, thereby scraping away the solid lubricant adhering to the inner wall of the crushing cylinder 31, allowing it to be crushed again, further improving the uniformity of the crushing process.

[0036] Please refer to Figures 3-4 and Figures 6-7The baffle assembly 5 includes a baffle arc plate 51 that fits against the outer wall of the crushing cylinder 31 and sliding grooves 54 installed on both sides of the crushing cylinder 31. The baffle arc plate 51 is arranged along the axis of the crushing cylinder 31, and the inner wall of the baffle arc plate 51 fits against the outer wall of the crushing cylinder 31. Multiple connectors 52 are installed on the side walls at both ends of the baffle arc plate 51, and each connector 52 is rotatably connected to a pulley 53 at its end. The sliding grooves 54 are respectively installed on the side walls of the crushing cylinder 31, and the sliding grooves 54 are set as arc structures adapted to the circumference of the crushing cylinder 31, with the center of the sliding grooves 54 coinciding with the center of the crushing cylinder 31. The multiple pulleys 53 connected to the baffle arc plate 51 are slidably installed in the sliding grooves 54. When the pulleys 53 slide relative to the sliding grooves 54, they can synchronously drive the baffle arc plate 51 to rotate along the direction of fitting against the outer wall of the crushing cylinder 31. When no external force is applied, the baffle plate 51 is located at the bottom of the crushing cylinder 31 under the action of gravity and corresponds to the position of the filter hole 35 on the crushing cylinder 31. It can block the filter hole 35 and prevent the solid lubricant in the crushing cylinder 31 from leaking out through the filter hole 35 during the crushing process.

[0037] Specifically, the solid lubricant enters the feed hopper 21 for pre-crushing. The pre-crushing motor 22 drives the first crushing shaft 23 to rotate, simultaneously driving the second crushing shaft 24 to rotate. During the rotation of the first and second crushing shafts 23 and 24, the pre-crushing cutter 25 on them rotates synchronously, pre-crushing the solid lubricant to reduce its fineness, facilitating subsequent secondary crushing. After secondary crushing, the solid lubricant flows downward into the discharge hopper 26, and finally enters the crushing cylinder 31 through the discharge hopper 26. The crushing motor 33 drives the third crushing shaft 32 to rotate. During the rotation of the third crushing shaft 32, on the one hand, it drives the crushing cutter 34 to rotate synchronously, using the crushing cutter 34 to further crush the solid lubricant in the crushing cylinder 31; on the other hand, it also drives the mounting rod 41 to rotate synchronously, and the scraper 43 adheres to the inner wall of the crushing cylinder 31, scraping off the solid lubricant adhering to the inner wall of the crushing cylinder 31, allowing it to be crushed again, further improving the uniformity of crushing. During the secondary crushing process, the baffle plate 51 is located at the bottom of the crushing cylinder 31, sealing the filter hole 35 to prevent solid lubricant from leaking out of the crushing cylinder 31 through the filter hole 35. Simultaneously, during the crushing of the solid lubricant, the scraper plate 43 and the crushing cutter 34 work together. After the scraper plate 43 scrapes off the lubricant, the solid lubricant contacts the crushing cutter 34 during its fall, thoroughly dispersing the solid lubricant in the crushing cylinder 31, improving the uniformity of dispersion, and reducing the probability of solid lubricant accumulation within the crushing cylinder 31. During the crushing process, the baffle plate 51 seals the filter hole 35 to prevent solid lubricant from leaking out of the crushing cylinder 31 through the filter hole 35.

[0038] After crushing, the pulley 53 is pushed to slide relative to the chute 54, simultaneously driving the baffle plate 51 to rotate along the direction of adhering to the outer wall of the crushing cylinder 31, thereby opening the filter hole 35. As the third crushing shaft 32 continues to rotate, the scraper plate 43 continuously discharges solid lubricant from the filter hole 35, thereby completing the feeding in a short time and reducing the splashing of solid lubricant during the feeding process.

[0039] First, the solid lubricant is pre-crushed by the rotation of the first crushing shaft 23 and the second crushing shaft 24 using the pre-crushing cutter 25 to reduce its fineness. Then, the rotation of the third crushing shaft 32 drives the crushing cutter 34 to further crush the solid lubricant in the crushing cylinder 31. This multi-stage crushing method improves the thoroughness of crushing and thus enhances the uniformity of the solid lubricant particle size. At the same time, the scraper 43, in conjunction with the crushing cutter 34, can also fully disperse the solid lubricant in the crushing cylinder 31, increasing its dispersion within the cylinder and preventing accumulation of solid lubricant from affecting the degree of crushing.
