Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to an adjustable grinding equipment for producing curing agents. Background Technology
[0002] Grinding equipment for curing agent production is used to grind curing agent raw materials to a specific fineness. One type is a three-roll milling device, which has the following structure:
[0003] 1. Housing and three grinding rollers: The three grinding rollers are the feed roller, the intermediate roller and the discharge roller. The three grinding rollers are installed in the housing and are driven by the drive mechanism to rotate at different speeds. The raw material enters from the gap between the feed roller and the intermediate roller, is ground under the squeezing and shearing action of the rollers, and is then discharged from the gap between the intermediate roller and the discharge roller, thus completing the grinding process.
[0004] 2. Adjustment mechanism: This is used to adjust the gap between each grinding roller to control the grinding fineness of the curing agent. It is usually composed of components such as adjusting handwheel and connecting rod. The operator changes the gap between the rollers by rotating the adjusting handwheel.
[0005] When workers need to adjust the gap between the three grinding rollers, they need to turn the adjusting handwheel. When the gap is small, the amount of rotation of the adjusting handwheel is extremely small, often only a fraction of a turn or even a smaller angle is required. However, in this process, the manual operation of the workers has unavoidable limitations: natural hand tremors, uneven force application, and perceptual deviations in the small rotation angle. These factors can easily lead to differences in the actual rotation amplitude of the two adjusting handwheels. These differences cause deviations in the gap between the grinding rollers, which in turn causes uneven force on the hardener during the grinding process. This results in some particles being ground too coarsely or some particles being ground too finely, affecting the overall uniformity of the hardener and ultimately leading to a decrease in the quality of the hardener. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable grinding device for curing agent production. It solves the problem that when the adjustment gap is small, the rotation of the adjusting handwheel is extremely small, often requiring only a fraction of a turn or even a smaller angle. However, manual operation by the operator has unavoidable limitations: natural hand tremors, uneven force application, and perceptual deviations in minute rotation angles. These factors easily lead to differences in the actual rotation amplitude of the two adjusting handwheels. These differences cause deviations in the gap between the grinding rollers, resulting in uneven force on the curing agent during grinding. This leads to some particles being ground too coarsely or too finely, affecting the overall uniformity of the curing agent and ultimately causing a decline in its quality.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An adjustable grinding device for producing curing agents includes a housing and two adjusting handwheels. Each side of the housing corresponding to one of the handwheels is provided with a measuring component for measuring the rotation range of the handwheel. The measuring component includes two scales. Each handwheel has a pointer on its exterior, one end of which moves along the scale as the handwheel rotates. Each side of the housing corresponding to one scale is provided with a fixing mechanism for securing the scale. Each fixing mechanism includes a positioning block, a nut, and a bolt. The positioning block is fixedly installed on the exterior of the housing, the scale is engaged with the exterior of the positioning block, the nut is located on the exterior of the positioning block, and the bolt is threaded into the interior of the nut to limit the movement of the scale.
[0009] Preferably, each positioning block has an external mounting groove, the nut is engaged inside the mounting groove, and each positioning block has a through hole on the side corresponding to the mounting groove, and the bolt is threaded into the nut through the through hole.
[0010] Preferably, each adjusting handwheel is fixedly mounted with a reference shaft, and each housing is provided with a measuring plate. The two ends of the measuring plate are located on the upper surface of the two reference shafts, and two storage racks for placing the measuring plates are fixedly mounted on the outside of the housing.
[0011] Preferably, each adjustment handwheel has a movable groove on its outside, and the end of the pointer away from the scale is slidably connected to the inside of the movable groove. A spring is fixedly connected inside each movable groove, and the pointer is fixedly connected to the end of the spring.
[0012] Preferably, each bolt has a washer that is movably fitted onto its exterior.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] One end of the dial is slidably connected to the outside of the positioning block. At this time, the bolt is threaded into the inside of the nut and used to restrict the movement of the dial. The edges of the two dials corresponding to the same adjustment handwheel are tightly fitted to form a continuous scale surface, and their scale lines are precisely aligned. During operation, when the adjustment handwheel is rotated, the pointer rotates synchronously with the adjustment handwheel and forms a continuous indicating trajectory on the fitted dial. By observing the displacement difference between the two pointers, the rotation amplitude of the two adjustment handwheels can be intuitively controlled to be consistent, effectively avoiding grinding gap deviation caused by adjustment differences, ensuring the uniformity of hardener particle grinding, and thus ensuring the production quality of hardener products.

[0023] This application provides an adjustable grinding device for producing curing agents, effectively solving the problem that when the adjustment gap is small, the rotation of the adjustment handwheel is extremely small, often only a fraction of a turn or even a smaller angle is required. However, in this process, manual operation by the operator has unavoidable limitations: natural hand tremors, uneven force application, and perceptual deviations in minute rotation angles. These factors can easily lead to differences in the actual rotation amplitude of the two adjustment handwheels. These differences cause deviations in the gap between the grinding rollers, resulting in uneven force on the curing agent during grinding. Consequently, some particles are ground too coarsely or too finely, affecting the overall uniformity of the curing agent and ultimately leading to a decrease in the quality of the curing agent.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5and Figure 6 As shown, the technical solution in this application effectively solves the problem that when the adjustment gap is small, the rotation of the adjustment handwheel is extremely small, often only a fraction of a turn or even a smaller angle is required. However, in this process, manual operation by the operator has unavoidable limitations: natural hand tremors, uneven force application, and perceptual deviations in minute rotation angles. These factors can easily lead to differences in the actual rotation amplitude of the two adjustment handwheels. These differences cause deviations in the gap between the grinding rollers, resulting in uneven force on the curing agent during grinding. This leads to some particles being ground too coarsely or some particles being ground too finely, affecting the overall uniformity of the curing agent and ultimately causing a decrease in the quality of the curing agent. The overall approach is as follows:
[0026] To address the problems existing in the prior art, this utility model provides an adjustable grinding device for producing curing agents, including a housing 1 and two adjusting handwheels 2. Each side of the housing 1 corresponding to each adjusting handwheel 2 is provided with a measuring component for measuring the rotation range of the adjusting handwheel 2. The measuring component includes two scales 3. Each adjusting handwheel 2 has a pointer 4 on its exterior. One end of the pointer 4 moves on the scale 3 as the adjusting handwheel 2 moves. The adjustment range is quantified by the change in the position of the pointer 4 on the scale 3. Each side of the housing 1 corresponding to each scale 3 is provided with a fixing mechanism for fixing the scale 3. Each fixing mechanism includes a positioning block 5, a nut 6, and a bolt 7. The positioning block 5 is fixedly installed on the exterior of the housing 1, the scale 3 is snapped onto the exterior of the positioning block 5, the nut 6 is located on the exterior of the positioning block 5, and the bolt 7 is threaded into the interior of the nut 6 and used to limit the movement of the scale 3.
[0027] Each positioning block 5 has an external mounting groove 8, and the nut 6 is snapped into the inside of the mounting groove 8. Each positioning block 5 has a through hole 9 on the side corresponding to the mounting groove 8. The bolt 7 is threaded into the inside of the nut 6 through the through hole 9, which facilitates the replacement of the nut 6. That is, when the nut 6 is damaged, the nut 6 is pulled upward to disengage the nut 6 from the mounting groove 8.
[0028] Each adjustment handwheel 2 is fixedly mounted with a reference shaft 10 on its exterior, and a measuring plate 11 is provided on the exterior of the housing 1. The two ends of the measuring plate 11 are located on the upper surfaces of the two reference shafts 10 respectively, which solves the calibration problem when the pointer 4 is in the scale blind zone. By utilizing the high-precision characteristics of planar contact, the adjustment error of the dual wheels is controlled within a small range, thereby improving the synchronous adjustment accuracy.
[0029] Two storage racks 12 for placing measuring plates 11 are fixedly installed on the outside of the housing 1. The storage racks 12 are L-shaped.
[0030] Each adjusting handwheel 2 has a moving groove 13 on its outside. The end of the pointer 4 away from the dial 3 is slidably connected to the inside of the moving groove 13. A spring 14 is fixedly connected inside each moving groove 13. The pointer 4 is fixedly connected to the end of the spring 14. When the dial 3 is installed, push the pointer 4 to make the pointer 4 away from the housing 1. At this time, put the dial 3 on the threaded part of the adjusting handwheel 2, and then push the dial 3 to make the dial 3 snap into the outside of the positioning block 5.
[0031] Each bolt 7 is fitted with a washer 15 to prevent local compression deformation of the positioning block 5 when the bolt 7 is tightened, and at the same time enhances the anti-loosening effect of the threaded connection.
[0032] Example 1
[0033] One end of the dial 3 is slidably connected to the outside of the positioning block 5. At this time, the bolt 7 is threaded into the inside of the nut 6 and used to restrict the movement of the dial 3. At this time, the edges of the two dials 3 corresponding to the same adjusting handwheel 2 are tightly attached to form a continuous scale surface, and their scale lines are precisely aligned. When operating, the adjusting handwheel 2 is rotated, and the pointer 4 rotates synchronously with the adjusting handwheel 2 and forms a continuous indicating trajectory on the attached dial 3. By observing the displacement difference of the pointers 4 on both sides, the rotation amplitude of the two adjusting handwheels 2 can be intuitively controlled to be consistent, effectively avoiding the grinding gap deviation caused by adjustment differences, and ensuring the uniformity of the grinding of the curing agent particles.
[0034] Example 2
[0035] When pointer 4 is in the blind zone between two adjacent scale lines on dial 3, first coarsely adjust the second adjustment handwheel 2 so that pointer 4 is close to the target scale range. Place the measuring plate 11 horizontally so that the measuring plate 11 is completely in contact with the reference axis 10 corresponding to the first adjustment handwheel 2. At this time, slowly rotate the second adjustment handwheel 2 and observe the displacement of pointer 4 and the attitude change of the reference axis 10 until the reference axis 10 corresponding to the second adjustment handwheel 2 contacts and is in contact with the measuring plate 11. At this time, pointer 4 is just aligned with the target scale line, completing the fine calibration. This operation improves the synchronization accuracy of the dual-wheel adjustment by using the horizontal reference function of the measuring plate 11.
[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
