Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat exchange technology, and specifically relates to an adjustable and corrective double roller grinding machine. Background Technology
[0002] A double-roll mill is a device used to grind high-viscosity materials (such as pigments, inks, colloids, coatings, etc.). It grinds the material into finer particles through the squeezing and relative motion of two rollers. It features simple structure, convenient operation, and good grinding effect, and is widely used in the chemical, food, and pharmaceutical industries.
[0003] In the actual grinding process of a roller mill, misalignment and imbalance between the two rollers can occur. This misalignment and imbalance leads to poor grinding results and reduced product quality, such as uneven surface texture and inconsistent thickness. Furthermore, if the rollers remain misaligned during prolonged operation, it can cause excessive wear and even breakage, thus affecting the equipment's lifespan. Therefore, alignment technology is crucial for the normal operation of the roller mill and improving grinding efficiency. Traditional alignment methods typically involve manually observing roller misalignment and adjusting the roller position. This method relies on the operator's experience and observation skills, carries the risk of human error and delays, and significantly impacts production efficiency. Utility Model Content

Detailed Implementation
[0019] The present invention will now be described with reference to the accompanying drawings. Several improvements and modifications will be made to the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention. Example 1
[0020] like Figures 1-2 As shown, an adjustable-correction double-roll grinding machine includes a frame 1, a first grinding roller 2 and a second grinding roller 3 mounted on the frame 1, and two sets of correction devices 4 symmetrically mounted on both sides of the frame. The first grinding roller 2 and the second grinding roller 3 cooperate with each other. The correction device 4 includes an active adjustment component 4-1, a driven adjustment component 4-2, a pressure sensor 4-3, and a controller. The active adjustment component 4-1 is fixedly connected to the end bearing seat of the first grinding roller 2, and the driven adjustment component 4-2 is fixedly connected to the end bearing seat of the second grinding roller 3, and is also fixedly connected to the active adjustment component 4-1. Components 4-1 are located on the same side. The active adjustment component 4-1 is fixedly installed on the frame 1, and the driven adjustment component 4-2 is rotatably installed on the frame 1. The active adjustment component 4-1 and the driven adjustment component 4-2 are connected through a pressure sensor 4-3. The controller is installed on the frame 1. The pressure sensor feeds back the monitored data to the controller in real time. The controller controls the active adjustment component 4-1 to drive the driven adjustment component 4-2 to rotate the second grinding roller 3 around the rotatable connection point, which is used to adjust the relative position between the second grinding roller 3 and the first grinding roller 2.
[0021] In this embodiment 1, as Figures 3-5 As shown, the active adjustment component 4-1 includes an active bearing housing 4-11, an active drive device 4-12, an active gear 4-13, a driven gear 4-14, a driven gear shaft 4-15, and a connecting component 4-16. The active bearing housing 4-11 is fixedly installed with the end bearing housing (not shown) of the first grinding roller 2, and the lower end of the active bearing housing 4-11 is fixedly installed on the frame 1. The active drive device 4-12 is installed on the upper end of the active bearing housing 4-11, and the output end of the active drive device 4-12 is connected to the active gear 4-13. The active gear 4-13 and... The driven gears 4-14 mesh with each other and are mounted on the driven gear shaft 4-15, driving the driven gear shaft 4-15 to rotate. One end of the driven gear shaft 4-15 is threadedly connected to one end of the connecting assembly 4-16. The other end of the driven gear shaft 4-15 is rotatably mounted on the upper end of the driving bearing seat 4-11 through several bearings (e.g., two deep groove ball bearings). The other end of the connecting assembly 4-16 is connected to the pressure sensor 4-3. The central axes of the driven gears 4-14 and the driving gear 4-13 are located in the same vertical plane.
[0022] In this embodiment 1, the active adjustment component 4-1 further includes a spring washer 4-17 and a spring 4-18. The spring washer 4-17 is installed at the shaft center of the driven gear 4-14, and the spring 4-18 is sleeved on the driven gear shaft 4-15. Both ends of the spring 4-18 are in contact with the spring washer 4-17 and the connecting component 4-16, respectively. In this invention, by installing the spring 4-18 between the spring washer 4-17 and the connecting component 4-16, the threaded connection between the connecting component 4-16 and the driven gear shaft 4-15 is prevented from developing gaps during clearance adjustment, thus ensuring connection stability.
[0023] In this embodiment 1, the connecting assembly 4-16 includes a U-shaped fork 4-161 and a connecting seat I 4-162. The connecting end of the U-shaped fork 4-161 is threadedly connected to the driven gear shaft 4-15, and the open end of the U-shaped fork 4-161 is connected to the connecting seat I 4-162 via an upper pin 5. The connecting seat I 4-162 is fixedly connected to the pressure sensor 4-3. In this utility model, the structure of the connecting assembly 4-16 can be, but is not limited to, the above structure; any existing connecting assembly that can achieve a threaded connection with the driven gear shaft is applicable.
[0024] In this embodiment 1, the active drive device 4-12 includes a drive motor 4-121 and a reducer 4-122. The output end of the drive motor 4-121 is connected to the input end of the reducer 4-122, and the output end of the reducer 4-122 is connected to the drive gear 4-13 for transmission. In this utility model, the structure of the active drive device 4-12 can be, but is not limited to, the above-described structure; any existing drive device capable of rotating the driven gear shaft can be applied.
[0025] In this embodiment 1, the driven adjustment component 4-2 includes a driven bearing seat 4-21 and a connecting seat II 4-22. One end of the connecting seat II 4-22 is connected to the pressure sensor 4-3, and the other end is connected to the upper end of the driven bearing seat 1 through the upper pin 5. The driven bearing seat 4-21 is fixedly installed with the end bearing seat of the second grinding roller 3. The lower end of the driven bearing seat 4-21 is installed on the frame 1 through the lower pin 6 and can rotate around the lower pin 6.
[0026] The working principle of this utility model is as follows: Before grinding begins, preset grinding parameters, including the pressure parameters between the first grinding roller 2 and the second grinding roller 3, can be set according to the type of grinding material and product quality requirements. The controller then adjusts the parameters based on the real-time pressure feedback from the pressure sensor. When the real-time pressure value exceeds the preset pressure parameter, the controller controls the drive motor 4-121 to rotate, thereby driving the drive gear 4-13 to rotate via the driven gear 4-14, which in turn drives the driven gear shaft 4-15 to rotate. Since the driven gear shaft 4-15 and the connecting assembly 4-16 are threadedly connected, the threaded rotation causes the connecting assembly 4-16 to rotate outwards, thereby driving the driven adjustment assembly 4-2 to rotate the second grinding roller 3 around the lower pin 6 in a direction away from the first grinding roller 2, thus increasing the distance between the two rollers, and vice versa, thereby achieving dynamic balance during the grinding process. In this utility model, the two sets of correction devices located on both sides of the frame can be independently adjusted according to the real-time monitoring values of the pressure sensor.
[0027] The above description is merely an illustration of the present utility model and represents a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the scope of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
