Description

Technical Field

[0001] This utility model relates to the technical field of lubricant production equipment, and in particular to a multi-roller grinding machine for lubricants. Background Technology

[0002] In the production process of lubricants, multi-roll mills are one of the commonly used pieces of equipment. Their working principle is based on the precise speed difference and pressure coordination between multiple grinding rollers to continuously squeeze, shear and refine the lubricant raw materials, aiming to make the final product meet strict standards of fineness and uniformity.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: During the grinding operation, due to the difficulty in achieving precise and uniform pressure distribution between the grinding rollers, some lubricant may not be fully ground. This insufficiently ground lubricant will flow directly out of the discharge guide plate along with the standard-compliant and fully ground lubricant, and mix with it in the receiving container. As a result, the mixed lubricant is very likely to experience a decrease in lubrication performance in various actual use scenarios, failing to fully meet the lubrication requirements of the corresponding equipment; therefore, a multi-roller lubricant grinding machine is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem in existing grinding technologies where, due to the difficulty in achieving precise and uniform pressure distribution among the grinding rollers, some lubricant may not be fully ground. This insufficiently ground lubricant will flow directly out of the discharge guide plate along with the fully ground lubricant that meets the standards, mixing with it in the receiving container. Consequently, the mixed lubricant is highly likely to experience reduced lubrication performance in various actual use scenarios, failing to fully meet the lubrication requirements of the corresponding equipment. Therefore, this invention proposes a multi-roller lubricant grinding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-roller grinding machine for lubricants, comprising a multi-roller grinding machine body, wherein a plurality of grinding rollers are installed inside the multi-roller grinding machine body, and a discharge guide plate is installed inside the multi-roller grinding machine body. Two sliding holes are opened on the surface of the discharge guide plate, and two collection chambers are fixedly connected to the lower surface of the discharge guide plate. A square hole is opened on the upper surface of each of the two collection chambers, and the square hole communicates with the sliding hole. A filter plate is fixedly connected to the surface of the discharge guide plate, and a collection box is slidably inserted into the collection chamber. Two fixing plates are fixedly connected to one side of the collection chamber, and a threaded rod is rotatably connected inside the fixing plate. A slider is threadedly connected to the arc surface of the threaded rod, and the slider is slidably connected to the inner wall of the fixing plate. A fixing block is fixedly connected to the upper surface of the slider, and a round shaft is fixedly connected to one end of the threaded rod.

[0006] The effect achieved by the above components is as follows: by setting a filter plate on the discharge guide plate, it can accurately intercept solid lubricants that are not sufficiently ground and have large particles. With the collection bin and the slidable collection box, these insufficiently ground lubricants can be effectively collected. Subsequently, the lubricant in the collection box can be conveniently put back into the grinding roller for re-grinding, ensuring the grinding quality of the lubricant and preventing insufficiently ground lubricant and fully ground lubricant from flowing out directly together.

[0007] Preferably, a soft pad is fixedly connected to the inner wall of the fixing block, and the soft pad is made of rubber.

[0008] The effect achieved by the above components is that the rubber pads increase the friction with the surface of the collection box, making the collection box more stable in the collection chamber and preventing it from accidentally slipping out.

[0009] Preferably, the circular arc surface of the circular shaft is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are arranged in a circumferential array.

[0010] The effects achieved by the above components are as follows: the anti-slip groove can effectively increase the friction between the operator's hand and the shaft when rotating the shaft, preventing the hand from slipping during operation, making the operation of rotating the shaft and adjusting the threaded rod easier, more stable and more precise, and thus facilitating the adjustment and control of components such as the collection box, improving the convenience and reliability of equipment operation.

[0011] Preferably, the filter plate is triangular in shape and is made of metal.

[0012] The effects achieved by the above components are as follows: the triangular filter plate helps guide the material to flow into the sliding holes, improves the filtration efficiency, and allows insufficiently ground particles to enter the collection box more smoothly, further improving the control of the grinding quality of the lubricant. The metal material gives the filter plate high strength and wear resistance, and it can maintain good filtration performance for a long time in the face of hard particles that may be present in the lubricant and frequent filtration work.

[0013] Preferably, two guide plates are fixedly connected to the surface of the discharge guide plate, and the surface of the discharge guide plate is coated with a nano-composite coating.

[0014] The effects achieved by the above components are as follows: During the grinding process, the lubricant is most likely to be insufficiently ground at both ends of the grinding roller, resulting in accumulation. The guide plate can guide the accumulated lubricant flowing down from both ends of the grinding roller into the sliding hole in advance, avoiding the filter plate from being blocked by too much lubricant. The nano-composite coating, with its excellent non-stick properties, prevents the accumulated lubricant from sticking to the surface of the discharge guide plate, ensuring that the lubricant can flow smoothly along the guide plate.

[0015] Preferably, a U-shaped block is fixedly connected to one side of the collection box.

[0016] The effect achieved by the above-mentioned components is that the U-shaped block provides a convenient point of leverage for operating the collection box. When it is necessary to insert or remove the collection box, the operator can directly hold the U-shaped block, which is more convenient and stable for applying force compared to direct contact with the collection box.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, by setting a filter plate on the discharge guide plate, it is possible to accurately intercept solid lubricants that are not sufficiently ground and have large particles. With the collection bin and the slidable collection box, these insufficiently ground lubricants can be effectively collected. Subsequently, the lubricant in the collection box can be conveniently put back into the grinding roller for re-grinding, ensuring the grinding quality of the lubricant and preventing insufficiently ground lubricant and fully ground lubricant from flowing out directly together.

[0024] Reference Figures 1-4As shown, this utility model provides a technical solution: a multi-roller grinding mill for lubricants, including a multi-roller grinding mill body 1, a plurality of grinding rollers 2 installed inside the multi-roller grinding mill body 1, a discharge guide plate 3 installed inside the multi-roller grinding mill body 1, two sliding holes 4 formed on the surface of the discharge guide plate 3, two collection bins 6 fixedly connected to the lower surface of the discharge guide plate 3, square holes formed on the upper surface of each of the two collection bins 6, the square holes communicating with the sliding holes 4, a filter plate 5 fixedly connected to the surface of the discharge guide plate 3, a collection box 7 slidably inserted inside the collection bin 6, two fixing plates 8 fixedly connected to one side of the collection bin 6, a threaded rod 9 rotatably connected inside the fixing plate 8, and a slider 1 threadedly connected to the arc surface of the threaded rod 9. 1. The slider 11 is slidably connected to the inner wall of the fixed plate 8. A fixed block 12 is fixedly connected to the upper surface of the slider 11. A round shaft 10 is fixedly connected to one end of the threaded rod 9. By setting a filter plate 5 on the discharge guide plate 3, it can accurately intercept solid lubricant that is not sufficiently ground and has large particles. With the collection bin 6 and the slidably insertable collection box 7, these insufficiently ground lubricants can be effectively collected. Subsequently, the lubricant in the collection box 7 can be conveniently put back into the grinding roller 2 for re-grinding, ensuring the grinding quality of the lubricant and preventing insufficiently ground lubricant and fully ground lubricant from flowing out directly together. A soft pad 13 is fixedly connected to the inner wall of the fixed block 12. The soft pad 13 is made of rubber. The rubber soft pad 13 can increase the efficiency of the lubricant grinding process. The frictional force applied to the surface of the collection box 7 makes the collection box 7 more stable within the collection chamber 6, preventing it from accidentally slipping out. The circular surface of the round shaft 10 is provided with several anti-slip grooves 14 arranged in a circumferential array. These anti-slip grooves 14 effectively increase the friction between the operator's hand and the round shaft 10 when rotating it, preventing slippage and making operations such as adjusting the threaded rod 9 easier, more stable, and more precise. This facilitates the adjustment and control of components such as the collection box 7, improving the convenience and reliability of equipment operation. The filter plate 5 is triangular and made of metal. The triangular filter plate 5 helps guide the material to flow towards the sliding holes 4, improving filtration efficiency and allowing insufficiently ground particles to pass through. The lubricant enters the collection box 7 more smoothly, further improving the control of the grinding quality. The metal material gives the filter plate 5 high strength and wear resistance, and it can maintain good filtration performance for a long time, even in the face of hard particles that may be present in the lubricant and frequent filtration. Two guide plates 16 are fixedly connected to the surface of the discharge guide plate 3. The surface of the discharge guide plate 3 is coated with a nano-composite coating. During the grinding process, the lubricant is most likely to be insufficiently ground at both ends of the grinding roller 2, causing accumulation. The guide plates 16 can guide the accumulated lubricant flowing down from both ends of the grinding roller 2 into the sliding holes 4 in advance, avoiding the filter plate 5 from being blocked by too much lubricant. The nano-composite coating, with its excellent non-stick properties, prevents the accumulated lubricant from sticking to the surface of the discharge guide plate 3.To ensure smooth flow of lubricant along the guide plate 16, a U-shaped block 15 is fixedly connected to one side of the collection box 7. The U-shaped block 15 provides a convenient point of leverage for operating the collection box 7. When inserting or removing the collection box 7, the operator can directly grasp the U-shaped block 15, which is more convenient and stable for applying force compared to direct contact with the collection box 7.

[0025] The working principle is as follows: the lubricant to be ground is fed into the multi-roller mill body 1 and ground by several grinding rollers 2. Due to uneven pressure distribution among the grinding rollers 2, insufficiently ground lubricant may be produced. The filter plate 5 on the discharge guide plate 3, with its high strength and wear resistance of metal material, accurately intercepts larger particles of insufficiently ground solid lubricant and guides the material flow to the sliding hole 4 through its triangular structure, allowing it to enter the collection box 7 in the collection bin 6 below. The guide plate 16 on the surface of the discharge guide plate 3 guides the lubricant that easily accumulates at both ends of the grinding rollers 2 to the sliding hole 4 in advance, preventing the filter plate 5 from clogging. The nano-composite coating also prevents the lubricant from sticking to the surface of the discharge guide plate 3, ensuring smooth flow. When a certain amount has accumulated, the operator rotates the round shaft 10 with anti-slip grooves 14, causing the threaded rod 9 to rotate backward. This causes the slider 11, which is threaded to the threaded rod 9, to move backward within the fixed plate 8. The fixed plate 8 then moves the rubber pad 13 backward, thereby releasing the collection box 7. The operator can then pull the collection box 7 out of the collection chamber 6 by holding the U-shaped block 15, and put the insufficiently ground lubricant into the multi-roller grinding machine body 1. Then, the collection box 7 is reinserted into the collection chamber 6. The operator rotates the round shaft 10 in the opposite direction to drive the threaded rod 9, which in turn drives the fixed block 12 to move forward until the fixed block 12 drives the rubber soft pad 13 to abut against the surface of the collection box 7. Then, the grinding roller 2 grinds the insufficiently ground lubricant to ensure the grinding quality of the lubricant.
