Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a self-adjusting support structure for the weighing bin of a roller press. Background Technology

[0002] Currently, in the domestic cement grinding process system, the roller press grinding system still occupies a dominant position. Its core advantage lies in "more extrusion and less grinding". Through the principle of high-efficiency material bed crushing, it has achieved the goals of significantly increasing production, greatly saving energy and improving cement quality.

[0003] In cement grinding systems, the stability of the support and the accuracy of material level monitoring in the steady-flow weighing hopper of a roller press directly affect the system's operating efficiency and product quality. Typically, the weighing hopper has three support points evenly distributed along its circumference. There are two main structural configurations: the first uses three load cells as three supports, and the second uses one load cell as the support, with the other two being mechanical supports. The first support structure provides accurate measurements, but it requires a large number of sensors, resulting in high cost and complex signal processing. The second support structure, while using one load cell, has two mechanical supports with a limited range of motion and is inflexible. Due to the uncertainty of material impact, these mechanical supports are prone to jamming with the hopper body, causing the weight of the weighing hopper to be unevenly distributed across the three support points, ultimately leading to inaccurate measurements. Furthermore, both of these support structures are rigid connections. When material collapses within the weighing hopper, causing vibrations, it can easily damage the load cells and even trigger floor resonance.

[0004] Therefore, a self-adjusting support structure for the weighing chamber of a roller press is needed that is low in cost, ensures measurement accuracy, and is not prone to damaging the weighing sensor. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a self-adjusting support structure for the weighing chamber of a roller press, which can achieve low cost, ensure measurement accuracy, and reduce the damage rate of weighing sensors caused by weighing chamber vibration.

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

[0007] A self-adjusting support structure for a weighing bin of a roller press includes a ring support mechanism for supporting the weighing bin in an annular shape. The lower end of the ring support mechanism has three pins that rotate evenly in the circumference. Each pin has two connecting plates that rotate. The lower ends of the two connecting plates corresponding to the same pin have a shock-absorbing mechanism that rotates.

[0008] The shock absorption mechanism includes a base plate fixed to the foundation, a track on the upper surface of the base plate, the track being arranged radially along the weighing bin, a sliding frame sliding on the track, the sliding frame being rotatably connected to two connecting plates, a stop seat being provided on the end of the track away from the weighing bin, and a shock absorption spring being provided between the stop seat and the sliding frame;

[0009] A weighing sensor is installed between the damping spring and the stop seat of one of the damping mechanisms.

[0010] Preferably, the upper middle part of the track is provided with a wheel groove, and there are two rollers that rotate laterally inside the sliding frame.

[0011] Preferably, a connecting groove is provided through the middle of the wheel groove, and a threaded block extends from the lower end of the stop into the connecting groove. An adjusting screw is threadedly connected to the threaded block, and the adjusting screw is rotatably connected to the outer end of the track along the track direction.

[0012] Preferably, the self-adjusting support structure for the weighing bin of the roller press further includes a ground ring, which is coaxially arranged with the ring support mechanism and fixedly connected to three base plates. The lower end of the base plate is provided with an arc-shaped groove that cooperates with the ground ring.

[0013] Preferably, the ring support mechanism includes a ring support seat for supporting the weighing bin, the ring support seat is provided with three support seats evenly distributed around its circumference, the lower ends of the three support seats are respectively rotatably connected to the pin shaft, the weighing bin is fitted with a fixed circular seat, and the circular seat rests in the ring support seat.

[0014] Preferably, a sliding column is vertically fixed on the base plate, the sliding column passing through the corresponding pin and slidably connected to the corresponding support seat.

[0015] Preferably, the annular seat and the ring support seat are spherically connected, and three connecting frames are evenly fixed to the lower end of the weighing chamber. The three connecting frames correspond one-to-one with the three support seats, and tension springs are installed between the corresponding connecting frames and the support seats.

[0016] Preferably, each of the three support seats has a mounting ear plate fixed on its outer side, and a limiting mechanism for symmetrical weight swing is installed on the three mounting ear plates.

[0017] Preferably, the limiting mechanism includes a limiting ring coaxially arranged with the ring support, and three connecting rods are evenly fixed circumferentially on the limiting ring, with the three connecting rods respectively mounted on three mounting lugs.

[0018] Preferably, one of the connecting rods has a thread on its outer surface, and the connecting rod is connected to an adjusting nut by the thread. The adjusting nut is rotatably connected to the corresponding mounting ear plate, and the other two connecting rods are slidably connected to the corresponding mounting ear plates.

[0019] The present invention has the following beneficial effects:

[0020] When the weighing bin is supported by the ring support mechanism, the gravity generated by the overall weight of the weighing bin and the ring support mechanism is converted by the three pins through the connecting plate and the fixed shaft into a force that causes the sliding frame to slide along the track away from the center of the ring support mechanism. This, in turn, compresses the damping springs. Therefore, when the weighing bin vibrates, the overall weight change of the weighing bin is converted into a compressive force on the damping springs. By utilizing the elasticity of the damping springs, the vibration is buffered, avoiding the impact of the weighing bin vibration on the load cell, thus reducing the damage rate of the load cell caused by the vibration of the weighing bin. In addition, due to the cooperation and circumferential uniform distribution of the pins, connecting plate and damping mechanism, the ring support mechanism is kept in a horizontal state, which in turn ensures that the compressive force on each damping spring is the same. That is, the weight of the weighing bin can be evenly distributed on the three damping springs, ensuring the accuracy of the load cell measurement and achieving the goal of using only one load cell at low cost.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] Combination Figure 1 , Figure 2 and Figure 5 A self-adjusting support structure for a weighing bin of a roller press includes a ring support mechanism 2 for annularly supporting the weighing bin 1. Three pins 3 rotate evenly around the lower end of the ring support mechanism 2, and two connecting plates 4 rotate on each pin 3. A damping mechanism 5 rotates at the lower end of each of the two connecting plates 4 corresponding to the same pin 3. The damping mechanism 5 includes a base plate 51 fixed to the foundation, a track 52 on the upper surface of the base plate 51, the track 52 being radially arranged along the weighing bin 1, a sliding frame 53 sliding on the track 52, the sliding frame 53 being rotatably connected to the two connecting plates 4, a stop 54 at the end of the track 52 away from the weighing bin 1, and a damping spring 55 between the stop 54 and the sliding frame 53. A weighing sensor 6 is installed between the damping spring 55 and the stop 54 of one of the damping mechanisms 5.

[0041] Specifically, the base plate 51 is provided with mounting holes for fixing to the foundation by anchor bolts. The track 52 is a T-shaped structure. The lower end of the sliding frame 53 is provided with a T-shaped groove that matches the track 52, so that the sliding frame 53 slides on the T-shaped track 52 through the T-shaped groove, thereby forming a radial movement of the sliding frame 53 towards or away from the center of the ring support mechanism 2. The upper end of the sliding frame 53 is fixed with a fixed shaft. The fixed shaft is parallel to the corresponding pin 3 and perpendicular to the corresponding track 52. The lower ends of the two connecting plates 4 are rotatably connected to the two ends of the fixed shaft, and the upper ends of the two connecting plates 4 are sleeved on the pin 3. The connecting plates 4 are in an inclined state with the upper end close to the center of the ring support mechanism 2 and the lower end away from the center of the ring support mechanism 2.

[0042] Therefore, when the weighing bin 1 is supported by the ring support mechanism 2, the gravity generated by the overall weight of the weighing bin 1 and the ring support mechanism 2 will be converted by the three pins 3 through the connecting plate 4 and the fixed shaft into the force that causes the sliding frame 53 to slide along the track 52 away from the center of the ring support mechanism 2. This force then forms a compression of the damping spring 55 by pressing the stop 54. When the stop 54 is stationary, the damping spring 55 is compressed. Thus, when the weight of the material in the weighing bin 1 changes or is subjected to uncertain material impact force, or when material collapse or other vibrations occur, the overall gravity change of the weighing bin 1 will be converted into a compressive force on the damping spring 55. The elasticity of the damping spring 55 forms a buffer against vibration. Furthermore, since the weighing sensor 6 is installed between the damping spring 55 and the stop 54 of one of the damping mechanisms 5, the impact of the weighing bin 1 vibration on the weighing sensor 6 is avoided, thus achieving the purpose of reducing the damage rate of the weighing sensor caused by the vibration of the weighing bin.

[0043] Meanwhile, since the three pins 3, the three damping mechanisms 5, and the connecting plate 4 between them are all evenly distributed circumferentially, and are perpendicular to the corresponding track 52 through the pins 3 and the fixed shaft and are connected to the rotation of the connecting plate 4, the ring support mechanism 2 is restricted to maintain a horizontal state, thereby making the compressive force on each damping spring 55 the same, that is, the weight of the weighing chamber 1 can be evenly distributed on the three damping springs 55, ensuring the accuracy of the measurement by the weighing sensor 6, and achieving the goal of low cost by using only one weighing sensor 6;

[0044] It should be noted that the force on the weighing sensor 6 is the compressive force on the shock-absorbing spring 55, which needs to be converted using trigonometric functions to obtain the weight of the weighing chamber 1.

[0045] Combination Figure 6 , Figure 8 , Figure 9 In some embodiments, a wheel groove 521 is provided in the middle of the upper end of the track 52, and two rollers 531 rotate laterally inside the sliding frame 53.

[0046] Specifically, the sliding frame 53 is an internally hollow frame structure. Each of the two rollers 531 has a roller shaft at its center. The two rollers 531 are located inside the sliding frame 53 and are rotatably connected to the sliding frame 53 through the roller shaft. A wheel groove 521 is opened on the upper end surface of the track 52 along the direction of the track 52, so that the sliding frame 53 can be connected by rolling within the wheel groove 521 through the two rollers 531, replacing the contact sliding connection between the sliding frame 53 and the upper end surface of the track 52. This improves the smoothness of the sliding frame 53 sliding on the track 52, reduces the friction between the two, and further improves the conversion of the weight of the weighing bin 1 through the sliding of the sliding frame 53.

[0047] Combination Figure 6 , Figure 7 , Figure 10 In some embodiments, a connecting groove 522 is provided through the middle of the wheel groove 521, and a threaded block 541 extends from the lower end of the stop 54 into the connecting groove 522. An adjusting screw 542 is threadedly connected to the threaded block 541, and the adjusting screw 542 is rotatably connected to the outer end of the track 52 along the track 52 direction.

[0048] Specifically, the connecting groove 522 provides sliding space for the threaded block 541. Rotating the adjusting screw 542 enables the threaded block 541 to engage with the adjusting screw 542, forming a threaded transmission to the threaded block 541. This causes the threaded block 541 to move along the track 52 within the connecting groove 522, which in turn drives the stop 54 to move along the track 52, thereby adjusting the distance between the stop 54 and the center of the ring support mechanism 2. This, in turn, adjusts the initial compression length of the damping spring 55, so that the elastic force of the damping spring 55 can adapt to the different weights of the weighing chamber 1 as a whole, reducing the vibration amplitude of the weighing chamber 1.

[0049] Combination Figure 7 11. In some embodiments, a self-adjusting support structure for the weighing bin of a roller press further includes a ground ring 7. The ground ring 7 is coaxially arranged with the ring support mechanism 2 and fixedly connected to three base plates 51. The lower end of the base plate 51 is provided with an arc groove 511 that cooperates with the ground ring 7.

[0050] Specifically, in order to ensure that the weight of the weighing chamber 1 is evenly distributed on the three damping springs 55, the three base plates 51 need to be evenly distributed circumferentially relative to the center of the ring support mechanism 2 during installation. Then, a ground ring 7 is set up. The ground ring 7 of the ring plate structure is laid flat on the ground and fixed to the three base plates 51 to form an initial fixation of the three base plates 51, thereby ensuring that the three base plates 51 are evenly distributed circumferentially. In addition, with the rotational connection of the pin shaft 3 and the fixed shaft to the connecting plate 4, the three base plates 51 are evenly distributed circumferentially relative to the center of the ring support mechanism 2.

[0051] By setting an arc-shaped groove 511 at the lower end of the base plate 51, the ground ring 7 can be embedded in the arc-shaped groove 511 when the base plate 51 is connected to the ground ring 7. This allows the three base plates 51 to be more quickly and evenly distributed on the ground ring 7, and then evenly distributed on the center of the ring support mechanism 2. This ensures that the weight of the weighing chamber 1 can be evenly distributed on the three damping springs 55, thereby ensuring the accuracy of the measurement by the weighing sensor 6.

[0052] Combination Figure 3-4 In some embodiments, the ring support mechanism 2 includes a ring support seat 21 for supporting the weighing bin 1. The ring support seat 21 is provided with three support seats 22 evenly distributed around its circumference. The lower ends of the three support seats 22 are rotatably connected to the pin shaft 3 respectively. A fixed circular seat 23 is fitted on the weighing bin 1 and rests inside the ring support seat 21.

[0053] Specifically, by coaxially mounting the ring seat 23 onto the outer surface of the weighing chamber 1, the ring support seat 21 can support the ring seat 23, thus forming a symmetrical support for the weighing chamber 1. The vertical downward extension of the support seat 22 provides a position for installing the pin 3 while bringing the pin 3 close to the foundation, thereby reducing the length of the connecting plate 4 and reducing the overall space occupied by the support structure.

[0054] It should be noted that one end of the pin 3 is provided with a stop, and the other end is provided with a pin hole for the cotter pin to pass through. Thus, during installation, both ends of the pin 3 are axially limited by the stop and the cotter pin, respectively.

[0055] Combination Figure 4-5 In some embodiments, a sliding column 56 is vertically fixed on the base plate 51, the sliding column 56 passes through the corresponding pin 3 and is slidably connected to the corresponding support seat 22.

[0056] The sliding column 56 is vertically fixed on the base plate 51 and slides through the pin 3 and the corresponding support seat 22, further forming a limit between the ring support mechanism 2 and the shock absorption mechanism 5, ensuring that the three shock absorption mechanisms 5 are evenly distributed in the circumference relative to the ring support mechanism 2, and providing stable support for the ring support mechanism 2.

[0057] Combination Figure 2-4 In some embodiments, the annular seat 23 and the ring support seat 21 are spherically connected, and three connecting frames 24 are evenly fixed to the lower end of the weighing chamber 1. The three connecting frames 24 correspond one-to-one with the three support seats 22, and tension springs 25 are installed between the corresponding connecting frames 24 and the support seats 22.

[0058] Specifically, the lower end of the ring seat 23 is provided with an outer spherical surface, and the upper end of the ring support seat 21 is provided with an inner spherical surface. The outer spherical surface and the inner spherical surface cooperate to form a spherical rotational connection, so that the ring support seat 21 supports the weighing chamber 1 symmetrically through the ring seat 23, while the weighing chamber 1 can also rotate spherically on the ring support seat 21 through the ring seat 23. At the same time, in order to ensure that the center line of the weighing chamber 1 is collinear with the center line of the ring support seat 21 when no external force is applied, three tension springs 25 are evenly distributed in the circumference. Through the joint tension in the three circumferential directions, it is ensured that the center line of the weighing chamber 1 is collinear with the center line of the ring support seat 21 when no external force is applied.

[0059] Therefore, in actual use, when the symmetrical weighing bin 1 is feeding material, due to the uncertainty of material impact, the material may generate a large lateral impact on the symmetrical weighing bin 1. As a result, the weighing bin 1 may rotate spherically on the ring support 21 through the ring seat 23 due to the impact force of the material, and then automatically return to the center through the combined action of the three tension springs 25. This eliminates the vibration caused by the uncertainty of material impact, reduces the influence of vertical gravity of the symmetrical weighing bin 1, and further reduces the damage rate of the weighing bin 1 vibration to the load cell 6.

[0060] Combination Figure 1-2 In some embodiments, mounting ear plates 26 are fixed on the outer sides of the three support bases 22, and limiting mechanisms 8 for symmetrical weight chamber 1 to swing and limit the movement are installed on the three mounting ear plates 26.

[0061] When the symmetrical weighing bin 1 is feeding material, the material may generate a large lateral impact on the symmetrical weighing bin 1, which will cause the weighing bin 1 to rotate at a large angle on the ring support 21 through the ring seat 23. As a result, the three tension springs 25 cannot automatically return to the center position. Therefore, a limiting mechanism 8 is set up to limit the deflection of the symmetrical weighing bin 1 on the ring support 21 through the ring seat 23, so as to avoid the weighing bin 1 tilting too much and failing to return to the center position automatically through the three tension springs 25, which would affect its use.

[0062] Combination Figure 12 In some embodiments, the limiting mechanism 8 includes a limiting ring 81 coaxially arranged with the ring support 21. Three connecting rods 82 are evenly fixed circumferentially on the limiting ring 81, and the three connecting rods 82 are respectively installed on three mounting ear plates 26.

[0063] Specifically, the limiting ring 81 is a circular ring structure, which is fixedly installed to the three mounting ears 26 by three connecting rods 82 respectively, so that the limiting ring 81 and the ring support 21 are coaxial and located above the ring support 21 and are fitted on the weighing chamber 1, while having a certain distance between them. Thus, when the weighing chamber 1 rotates at a large angle on the ring support 21 through the circular ring seat 23, the side of the weighing chamber 1 will contact the limiting ring 81, thereby forming a symmetrical limit for the deflection and tilt of the weighing chamber 1, preventing the weighing chamber 1 from deflecting and tilting too much and failing to automatically return to the correct position by the three tension springs 25, which would affect its use.

[0064] Furthermore, in some embodiments, one of the connecting rods 82 has threads on its outer surface, and the connecting rod 82 is connected to an adjusting nut 83 by the threads. The adjusting nut 83 is rotatably connected to the corresponding mounting ear plate 26, and the other two connecting rods 82 are slidably connected to the corresponding mounting ear plate 26 through them.

[0065] Specifically, since the limiting ring 81 is a fixed circular structure, the distance between it and the outer surface of the weighing chamber 1 remains unchanged. When the position of the limiting ring 81 remains unchanged, the maximum deflection angle of the weighing chamber 1 is fixed and cannot be adjusted. However, due to the different shapes and properties of the materials, the maximum deflection angles at which the three tension springs 25 can automatically return to center will be different. Therefore, when it is necessary to limit the maximum deflection angle of the weighing chamber 1, one of the connecting rods 82 is provided with a thread on its outer surface, and an adjusting nut 83 is provided on its corresponding mounting ear plate 26. Rotating the adjusting nut 83 causes the connecting rod 82 to move axially through the threaded engagement between the adjusting nut 83 and the threaded connecting rod 82. This, in turn, causes the limiting ring 81 to move vertically, thereby changing the horizontal position of the limiting ring 81. With the position of the center of the sphere between the ring seat 23 and the ring support seat 21 remaining unchanged, the maximum deflection tilt angle of the weighing chamber 1 decreases as the limiting ring 81 rises, and the maximum deflection tilt angle of the weighing chamber 1 increases as the limiting ring 81 falls. This achieves the purpose of adjusting the maximum deflection tilt angle of the symmetrical weighing chamber 1.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
