Description

Technical Field

[0001] This invention relates to the field of gypsum board production technology, and specifically to a support and adjustment mechanism for weighing gypsum boards. Background Technology

[0002] In the current gypsum board production process, the weight of the wet board after molding is an important indicator, as it significantly impacts the quality of the gypsum board. To effectively monitor and measure the performance parameters of the wet board, a sample board is taken after the second-stage cutting process, various data are measured, and then it is weighed on an electronic scale. The weight of the wet board is calculated by measuring the weight per square meter of gypsum board and then multiplying it by the total square meter count of the stack of gypsum boards. The second-stage operators regularly take samples for measurement and feed the data back to the first-stage operator. The first-stage operator then adjusts various parameters in real time based on this data to ensure the good quality of the gypsum board.

[0003] Manual sampling and weighing cannot accurately measure the weight of the entire gypsum board. Therefore, existing technology usually sets up a weighing sensor that rises slightly when the gypsum board arrives to weigh the entire gypsum board.

[0004] The gypsum board needs to be stopped during transport before it is weighed. The stopping position of the gypsum board varies each time, and the size of each gypsum board is also different. If the weighing sensor at a certain position deviates from the center of gravity of the gypsum board, it may cause the center of gravity of the gypsum board to become unstable, causing the gypsum board to fall off the platform during the weighing process and be damaged. Summary of the Invention

[0005] Therefore, the present invention provides a support and adjustment mechanism for weighing gypsum board, which effectively solves the problem in the prior art that when the weighing sensor at a specific position deviates from the center of gravity of the gypsum board, the center of gravity of the gypsum board may become unstable, causing the gypsum board to fall off the platform and be damaged during the weighing process.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a support and adjustment mechanism for weighing gypsum board, comprising a gravity sensor 1, a sliding track assembly 2, and an alignment and adjustment structure 3, the specific structure of which is as follows:

[0047] Gravity sensor 1 is set on the side of gypsum board roller conveyor 4. There are several gravity sensors 1. The gravity sensor 1 corresponds to the corner of gypsum board 5. The bottom of gravity sensor 1 is provided with a lifting structure 6. The distance between adjacent gravity sensors 1 is kept consistent.

[0048] The sliding track assembly 2 is arranged along the length of the plasterboard 5. A first sliding frame 9 and a second sliding frame 10 are slidably arranged in the sliding track assembly 2. The first sliding frame 9 and the second sliding frame 10 are staggered. A forward moving drive 7 is provided on the first sliding frame 9 at the first end. The forward moving drive 7 is used to drive the first sliding frame 9 at the first end to move along the length of the plasterboard 5. A misalignment drive 8 is provided between the first sliding frame 9 and the second sliding frame 10. The misalignment drive 8 drives the second sliding frame 10 located downstream to move backward relative to the first sliding frame 9 based on the forward movement of the first sliding frame 9, and drives the first sliding frame 9 located downstream to move backward relative to the first sliding frame 10 based on the forward movement of the first second sliding frame 10, so as to adjust the distance between the gravity sensors 1 and keep the distance consistent. The lifting structure 6 is provided on the first sliding frame 9 and the second sliding frame 10.

[0049] The alignment and adjustment structure 3 is set on the sliding track group 2. The front end of the alignment and adjustment structure 3 is provided with a push seat 31. The push seat 31 pushes the sliding track group 2 forward so that the gravity sensors 1 located at the beginning and end are symmetrically arranged at the bottom of the gypsum board 5 to be weighed through the first sliding frame 9 and the second sliding frame 10.

[0050] The gravity sensor 1 is electrically connected to the control module. A photoelectric sensor is installed on the gypsum board roller conveyor 4. The photoelectric sensor is used to detect the position and length of the gypsum board 5. The control module controls the misalignment drive component 8 to adjust the spacing of the gravity sensor 1 based on the length of the gypsum board 5, and pushes and adjusts the position of the sliding track group 2 based on the position of the gypsum board 5.

[0051] In this invention, multiple gravity sensors 1 are used to weigh the plasterboard 5 to prevent it from detaching. The position and length of the plasterboard 5 are detected by photoelectric sensors. The control module controls the misalignment drive component 8 to adjust the spacing of the gravity sensors 1 based on the length of the plasterboard 5, ensuring that the spacing of the gravity sensors 1 remains consistent. The position of the sliding track group 2 is adjusted based on the position of the plasterboard 5, so that the gravity sensors 1 located at the edge are symmetrically positioned at the bottom of the plasterboard 5. This ensures that the gravity sensors 1 are symmetrically, equally spaced, and evenly distributed at the bottom of the plasterboard 5, guaranteeing the stability of the weighing process and improving the accuracy of the weighing results.

[0052] In this invention, each of the first sliding frame 9 and the second sliding frame 10 is equipped with a gravity sensor 1. The movement of the first sliding frame 9 and the second sliding frame 10 drives the gravity sensor 1 to move as well. During the movement, the distance between the gravity sensors 1 gradually increases, and the distance between the gravity sensors 1 remains consistent.

[0053] The sliding trajectories of the first sliding frame 9 and the second sliding frame 10 are both along the length of the plasterboard 5, thereby realizing the position adjustment of the gravity sensor 1 in the length of the plasterboard 5. The upper part of the first sliding frame 9 is provided with a movable groove 11, and the upper part of the second sliding frame 10 is provided with a movable strip 12, which is slidably disposed in the movable groove 11. A driving gap 13 is formed between the first sliding frame 9 and the second sliding frame 10, and the misalignment driving component 8 is disposed in the driving gap 13. The lengths of the first sliding frame 9 and the second sliding frame 10 are the same.

[0054] The misalignment drive component 8 can also drive the second sliding frame 10 to move backward during the movement of the first sliding frame 9. Based on the forward movement of the first sliding frame 9, the second sliding frame 10 located downstream moves backward relative to the first sliding frame 9. Based on the forward movement of the second sliding frame 10, the first sliding frame 9 located downstream moves backward relative to the first second sliding frame 10. This adjusts the distance between the gravity sensors 1 and keeps the distance consistent. In other words, when the first first sliding frame 9 moves backward, it drives the second sliding frame 10 located behind it to move backward. Then, it can drive the first sliding frame 9 located behind it to move backward as well. Thus, through the linkage, all the first sliding frames 9 and the second sliding frame 10 can be driven to move backward.

[0055] The misalignment driving component 8 of the present invention adopts the following preferred embodiments, such as... Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the misalignment drive component 8 includes a first transmission gear 81 disposed on the inner wall of the first sliding frame 9 and a first connecting rack 82 disposed on the inner wall of the second sliding frame 10; a mounting frame 83 is installed on the side of the sliding track assembly 2, and a mounting crossbar 84 is connected to the mounting frame 83. A long rack 85 is disposed on the mounting crossbar 84. The long rack 85 on one side of the first transmission gear 81 meshes with the first connecting rack 82 on the adjacent second sliding frame 10 on the other side. The mounting crossbar 84 is disposed along the length direction of the gypsum board 5.

[0056] In the above embodiment, assuming the first sliding frame 9 at the head end moves backward a certain distance, the position of the long rack 85 remains unchanged, the first sliding frame 9 drives the first transmission gear 81 to move backward, the long rack 85 and the first transmission gear 81 move relative to each other, causing the first transmission gear 81 to rotate clockwise, the rotation of the first transmission gear 81 causes the first connecting rack 82 to move backward based on the first transmission gear 81, the distance the first connecting rack 82 moves backward relative to the first transmission gear 81 is the same as the distance the long rack 85 moves relative to the first transmission gear 81, that is, the second sliding frame 10 moves backward a certain distance based on the first sliding frame 9. Assuming the distance the first sliding frame 9 moves backward is x, then the distance the second sliding frame 10 moves backward is 2x, and the distance between the gravity sensor 1 on the first sliding frame 9 and the second sliding frame 10 increases by x.

[0057] In order to enable the movement of the second sliding frame 10 to drive the downstream first sliding frame 9 to move backward relative to the preceding second sliding frame 10, the present invention also includes the following design, such as Figure 6 , Figure 7 and Figure 8 As shown, the inner wall of the second sliding frame 10 is provided with a second transmission gear 86, and the inner wall of the first sliding frame 9 is provided with a second connecting rack 87; one side of the second transmission gear 86 meshes with the long rack 85, and the other side meshes with the second connecting rack 87 on the adjacent first sliding frame 9.

[0058] After the second sliding frame 10 moves backward along with the first sliding frame 9, the second transmission gear 86 on the second sliding frame 10 also moves backward. The long rack 85 remains in the same position, and the long rack 85 moves relative to the second transmission gear 86, causing the second transmission gear 86 to rotate clockwise. Under the rotation of the second transmission gear 86, the second connecting rack 87 moves backward. Therefore, the second connecting rack 87 moves backward based on the second transmission gear 86. That is to say, the first sliding frame 9 located in the latter position moves backward relative to the previous second sliding frame 10. Assuming that the distance the second sliding frame 10 moves backward is 2x, and the distance the second connecting rack 87 moves backward relative to the second transmission gear 86 is x, then the distance the second first sliding frame 9 moves backward is 3x. Therefore, the distance between the gravity sensor 1 on the second sliding frame 10 located in the second position and the first sliding frame 9 located in the third position increases by x, which is the same as the change in the distance of the gravity sensor 1 in the former position. Therefore, the distance of the gravity sensor 1 increases and remains consistent.

[0059] In this invention, each of the second sliding frames 10 is equipped with a first connecting rack 82 and a second transmission gear 86, and each of the first sliding frames 9 is equipped with a first transmission gear 81 and a second connecting rack 87. However, there is no second sliding frame 10 in front of the first sliding frame 9 at the beginning, and no corresponding transmission structure is required. Therefore, the second connecting rack 82 is not installed on the first sliding frame 9 at the beginning, and there is no first sliding frame 9 behind the second sliding frame 10 at the end. Correspondingly, the second transmission gear 86 is not installed on the second sliding frame 10 at the end.

[0060] In order to limit the distance of movement of the first sliding frame 9 and the second sliding frame 10, the present invention also makes the following design: the length of the first connecting rack 82 and the second connecting rack 87 is half the length of the first sliding frame 9 and the second sliding frame 10, and a stop bar 88 is provided at the end of the first connecting rack 82 and the second connecting rack 87, and the top height of the stop bar 88 is lower than the height of the long rack 85.

[0061] In the above embodiment, when the first transmission gear 81 and the second transmission gear 86 move close to the stop bar 88, the first transmission gear 81 and the second transmission gear 86 cannot continue to move backward. At this time, the first sliding frame 9 and the second sliding frame 10 are both braked. Assuming that the length of the first sliding frame 9 and the second sliding frame 10 is l, the backward movement distance of the first sliding frame 9 is limited to within 0.5l. Correspondingly, the increase in the distance between the gravity sensors 1 is also limited to within 0.5l.

[0062] In this invention, the forward-moving drive component 7 is used to drive the first sliding frame 9 located at the head end to move along the length direction of the gypsum board 5. The forward-moving drive component 7 of this invention adopts the following preferred embodiments, such as... Figure 3 and Figure 4 As shown, the forward drive component 7 includes a drive frame 71 disposed on the side of the sliding track assembly 2, a drive motor 72 disposed on the drive frame 71, a connecting shaft 73 disposed at the output end of the drive motor 72, and a connecting gear 74 disposed on the connecting shaft 73; a rack 75 is disposed on the outer wall of the first sliding frame 9 located at the head end, the connecting gear 74 meshes with the rack 75, and the length of the rack 75 is half the length of the first sliding frame 9.

[0063] The drive motor 72 drives the connecting shaft 73 to rotate, which in turn drives the connecting gear 74 to rotate. Under the rotation of the connecting gear 74, the rack 75 moves backward, which in turn drives the first sliding frame 9 to move backward.

[0064] The first sliding frame 9 and the second sliding frame 10 are both slidably mounted on the sliding track assembly 2, such as Figure 5 As shown, the sliding track assembly 2 includes an outer slide rail 21 and an inner slide rail 22; the outer slide rail 21 and the inner slide rail 22 are connected on the side, and the outer slide rail 21 and the inner slide rail 22 are provided with sliding grooves 23. The bottom of the first sliding frame 9 and the second sliding frame 10 are provided with sliding protrusions 24, and the sliding protrusions 24 are slidably disposed in the sliding grooves 23.

[0065] In the alignment and adjustment structure 3 of the present invention, the push seat 31 pushes the sliding track group 2 forward so that the gravity sensors 1 located at the beginning and end are symmetrically arranged at the bottom of the plasterboard 5 to be weighed through the first sliding frame 9 and the second sliding frame 10. That is, all the first sliding frames 9 and the second sliding frames 10 are moved backward or forward in order to adjust the gravity sensors 1 at the beginning and end to be symmetrically arranged at the bottom of the plasterboard 5.

[0066] The alignment and adjustment structure 3 of the present invention adopts the following preferred embodiments, such as... Figure 1 , Figure 2As shown, the alignment and adjustment structure 3 includes a mounting slot 32, a rotating threaded rod 33 disposed in the mounting slot 32, and a connecting motor 34 connected to the rotating threaded rod 33; the rotating threaded rod 33 is connected to the output end of the connecting motor 34, and the push seat 31 is threadedly connected to the rotating threaded rod 33. The push seat 31, the inner slide rail 22, and the outer slide rail 21 are all slidably disposed in the mounting slot 32.

[0067] The motor 34 drives the rotating threaded rod 33 to rotate. Under the rotation of the rotating threaded rod 33, the push seat 31 moves forward or backward, thereby pushing and pulling the inner slide rail 22 and the outer slide rail 21 to achieve overall symmetrical adjustment of the gravity sensor 1.

[0068] In this invention, the gypsum board 5 is lifted and weighed by the lifting structure 6. The lifting structure 6 of this invention adopts the following preferred embodiment: the lifting structure 6 includes a lifting frame 61 set on the first sliding frame 9 and the second sliding frame 10, a spiral rod 62 set on the lifting frame 61, and a lifting seat 63 set on the spiral rod 62; the gravity sensor 1 is installed on the lifting seat 63, and a rotary motor is connected to the spiral rod 62.

[0069] A rotary motor drives the screw rod 62 to rotate. Under the rotation of the screw rod 62, the lifting seat 63 moves upward, gradually lifting the gypsum board 5 and weighing it.

[0070] In summary, the main implementation process of this invention is as follows:

[0071] The gypsum board roller conveyor 4 transports the gypsum board 4 to the top of the weighing sensor 1. The photoelectric sensor detects the position and length of the gypsum board 5. The control module controls the misalignment drive component 8 to adjust the spacing of the gravity sensor 1 according to the length of the gypsum board 5.

[0072] The drive motor 72 drives the connecting shaft 73 to rotate, which in turn drives the connecting gear 74 to rotate. Under the rotation of the connecting gear 74, the rack 75 moves backward, which in turn drives the first sliding frame 9 to move backward. The first sliding frame 9 at the first end moves backward a certain distance, while the long rack 85 remains in the same position. The first sliding frame 9 drives the first transmission gear 81 to move backward, which in turn drives the first transmission gear 81 to rotate clockwise. This drives the first connecting rack 82 to move backward based on the first transmission gear 81, which in turn drives the second sliding frame 10 at the second position to move backward a certain distance based on the first sliding frame 9.

[0073] The second transmission gear 86 on the second sliding frame 10 moves backward, causing the second transmission gear 86 to rotate clockwise, which in turn causes the second connecting rack 87 to move backward. This causes the first sliding frame 9 in the third position to move backward relative to the second sliding frame 10 in the second position. And so on. Each sliding frame in the next position moves backward based on the previous sliding frame and the displacement relative to the previous sliding frame is consistent. The spacing of the gravity sensors 1 becomes larger and remains consistent, so that the gravity sensors 1 are evenly and completely distributed on the bottom of the gypsum board 5.

[0074] The control module pushes and adjusts the position of the sliding track group 2 based on the position of the gypsum board 5, and connects the motor 34 to drive the rotating threaded rod 33 to rotate. Under the rotation of the rotating threaded rod 33, the push seat 31 moves backward, thereby pushing and pulling the inner slide rail 22 and the outer slide rail 21, and driving the gravity sensor 1 to move as a whole, so that the gravity sensors 1 located at the beginning and end are symmetrically arranged at the bottom of the gypsum board 5.

[0075] The rotary motor drives the screw rod 62 to rotate. Under the rotation of the screw rod 62, the lifting seat 63 moves upward and gradually lifts the plasterboard 5. The plasterboard is weighed. After the weighing is completed, the lifting seat 63 is reset. The drive motor 72 rotates in the opposite direction to reset the first sliding frame 9 and the second sliding frame 10.
