Abstract
Description
Technical Field
[0001] This invention relates to the field of gypsum board production technology, specifically to an adaptive control weighing system and control method for gypsum board. 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 needs to be taken after the second-stage cutting process. After measuring various data, it is weighed on an electronic scale to calculate the unit weight of the wet gypsum board, which serves as a reference value for the unit weight of the finished board. 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 not only increases the labor intensity of employees, increases the probability of human error, and increases the cost of subsequent waste disposal, but also cannot accurately reflect the weight of the entire gypsum board. Therefore, existing technology usually uses a weighing sensor to lift the gypsum board slightly when it arrives, and weighs the entire gypsum board.
[0004] However, the size of the gypsum board that the weighing sensor can measure is fixed, while the size of the gypsum board on the gypsum board production line is not fixed. If the length of the gypsum board to be measured is too long, the weighing sensor itself is too small to support and perform the weight measurement of the entire gypsum board. Summary of the Invention
[0005] To address this issue, the present invention provides an adaptive control weighing system and method for gypsum board, which effectively solves the problem in the prior art where the size of the gypsum board does not match the size of the weighing device, resulting in the inability to support the gypsum board and perform the weight measurement of the entire gypsum board.

[0056] 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.
[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 13 As shown, the present invention provides an adaptive control weighing system for gypsum board, comprising a weighing element 1, a support and correction assembly 2, and a connection and drive assembly 3, the specific structure of which is as follows:
[0058] Weighing elements 1 are arranged at equal intervals on the gypsum board production line 4. Each set of weighing elements 1 contains two weighing sensors 5, and the two weighing sensors 5 are in the same position along the length of the gypsum board production line 4. A lifting structure 6 is provided at the bottom of the weighing elements 1.
[0059] The support and correction component 2 is set at the top of the lifting structure 6. A support sleeve 21 is formed at the top of the support and correction component 2. A translation seat 22 is movably arranged on the support sleeve 21. A first support roller 23 and a second support roller 24 are installed at the corner of the upper end face of the translation seat 22. The first support roller 23 is arranged along the length direction of the gypsum board 7, and the second support roller 24 is arranged along the width direction of the gypsum board. The first support roller 23 and the second support roller 24 abut against the gypsum board 7.
[0060] The connecting drive assembly 3 is disposed on the first support roller 23 and the second support roller 24. The connecting drive assembly 3 is used to drive the first support roller 23 and the second support roller 24 to move upward and lift the gypsum board 7, and to drive the gypsum board 7 to adjust its position along the length and width directions through the first support roller 23 and the second support roller 24.
[0061] The top of the lifting structure 6 is provided with a lifting platform 8, the weighing element 1 is provided on the lifting platform 8, and a lifting drive assembly 9 is provided between the lifting platform 8 and the support and correction assembly 2. The lifting drive assembly 9 drives the lifting platform 8 to rise and fall and drives the support and correction assembly 2 to rise and fall in the opposite direction.
[0062] The weighing element 1 is electrically connected to the control module. Several photoelectric sensors 10 are evenly spaced on the gypsum board production line 4. The photoelectric sensors 10 are used to monitor the length and position of the gypsum board 7. The control module controls the number of weighing sensors 5 that are raised and weighed based on the length of the gypsum board 7.
[0063] In this embodiment of the invention, multiple sets of weighing elements 1 are set on the gypsum board production line 4. Each set of weighing elements 1 includes two weighing sensors 5. The length and position of the gypsum board 7 are monitored by a photoelectric sensor 10. The control module controls the number of weighing sensors 5 that are raised and weighed according to the length of the gypsum board 7, thereby ensuring that the gypsum board 7 to be measured can be fully supported and tested. Furthermore, the relative position of the gypsum board 7 and the weighing sensors 5 is corrected by the support correction component 2 and the connection drive component 3, so that the center position of the gypsum board 7 is aligned with the center position of the weighing area formed by all the weighing sensors 7. This improves the overall measurement accuracy while ensuring complete support for the gypsum board 7.
[0064] In this invention, when the plasterboard 7 reaches the weighing position, the number of weighing sensors 5 for weighing is determined according to the length of the plasterboard 7. When the length of the plasterboard 7 is 6 meters, the first six weighing elements 1 (12 weighing sensors 5) rise and lift the plasterboard 7 to perform the weighing operation. When the length of the plasterboard 7 is 7 meters, the first seven weighing elements 1 (14 weighing sensors 5) rise and lift the plasterboard 7 to perform the weighing operation, and so on.
[0065] The first support roller 23 and the second support roller 24 in this invention are used to raise the gypsum board 7 and correct its position. To ensure that the first support roller 23 and the second support roller 24 can rise and raise the gypsum board 7 before correction, this invention is designed as follows: Figure 7As shown, a rotating shaft 25 is provided on both the first support roller 23 and the second support roller 24. The rotating shaft 25 is offset from the center of the first support roller 23 and the second support roller 24. The upper end face of the translation seat 22 is higher than the highest point of the transport roller on the gypsum board production line 4, and the highest point of the first support roller 23 and the second support roller 24 is higher than the height of the upper end face of the translation seat 22.
[0066] In the initial state, the highest points of the first support roller 23 and the second support roller 24 are inside the translation seat 22 and do not protrude outside the translation seat 22. At this time, the first support roller 23 and the second support roller 24 have not been lifted and corrected. Rotating the rotating shaft 25 drives the first support roller 23 and the second support roller 24 to rotate. Since the rotating shaft 25 is eccentrically set, when rotating, it gradually drives the highest points of the first support roller 23 and the second support roller 24 to move up, gradually approach the bottom surface of the gypsum board 7 and lift the gypsum board 7.
[0067] The translation seat 22 in this invention can lift the plasterboard 7 and move it to adjust the relative position of the plasterboard 7 and the weighing sensor 5. To prevent the translation seat 22 from interfering with the lifting platform 8 and the lifting sensor 5 during movement, this invention, as follows... Figure 4 and Figure 8 As shown, there are two translation seats 22, which are symmetrically arranged between the support sleeve 21. A through gap 26 is formed between the translation seats 22. The lifting platform 8 passes through the through gap 26. The width of the lifting platform 8 is the same as the width of the through gap 26. A through groove 27 is provided on the support sleeve 21. The size of the through groove 27 is the same as the size of the lifting platform 8.
[0068] During the movement of the translation seat 22, the lifting platform 8 is always positioned within the passage gap 26 and will not obstruct the translation movement of the translation seat 22.
[0069] In order to move the gypsum board 7 along its length, the translation seat 22 needs to be translated. Therefore, the support and correction assembly 2 of the present invention adopts the following preferred embodiment, such as... Figure 8 and Figure 9 As shown, the support and correction assembly 2 includes a sliding cavity 28 and a side groove 29 disposed within the support sleeve 21, a drive threaded rod 210 disposed within the sliding cavity 28, a drive worm gear 211 rotatably disposed within the side groove 29, and a drive worm 212 meshing with the side of the drive worm gear 211. Two sliding cavities 28 are provided and symmetrically disposed within the support sleeve 21. The side groove 29 is disposed on the side of the sliding cavity 28. A rotating rod 213 is provided at the end of the drive threaded rod 210. The rotating rod 213 penetrates the side wall of the sliding cavity 28 and extends into the side groove 29. The rotating rod 213 rotates coaxially with the drive worm gear 211. The drive worm 212 is rotatably disposed within the side groove 29. A first drive motor 214 is provided at the end of the drive worm 212, and the drive worm 212 is connected to the output end of the first drive motor 214.
[0070] The first drive motor 214 drives the drive worm 212 to rotate, which in turn drives the drive worm wheel 211 to rotate, causing the rotating rod 213 and the drive threaded rod 210 to rotate simultaneously. Under the rotation of the drive threaded rod 210, the translation seat 22 gradually moves within the sliding cavity 28, causing the gypsum board 7 at its upper end to adjust its position in the length direction.
[0071] In this invention, the connecting drive assembly 3 is used to drive the first support roller 23 and the second support roller 24 to move upward and lift the plasterboard 7. It also drives the plasterboard 7 to adjust its position along the length and width directions through the first support roller 23 and the second support roller 24. In other words, the connecting drive assembly 3 is used to correct the position of the plasterboard 7 after the translation seat 22 drives it to adjust its position. In addition to the position adjustment in the length direction, the position adjustment in the width direction is also realized.
[0072] The connection driving component 3 of the present invention adopts the following preferred embodiments, such as... Figure 10 As shown, the connecting drive assembly 3 includes a drive cavity 31 disposed in the translation seat 22, a second drive motor 32 disposed in the drive cavity 31, and a rotating shaft 25 connected to the output end of the second drive motor 32.
[0073] like Figure 7 and Figure 11 As shown, a rotating ring groove 33 is provided on the inner circumference of the first support roller 23 and the second support roller 24. A rotating ring 34 is rotatably arranged in the rotating ring groove 33. The outer wall of the rotating ring 34 protrudes out of the rotating ring groove 33. A connecting chamber 35 is provided on the outer wall of the first support roller 23 and the second support roller 24. The connecting chamber 35 is located on the extension line of the connecting line where the distance between the rotating shaft 25 and the outer circumference of the first support roller 23 and the second support roller 24 is the smallest. An opening 36 is provided on the side of the connecting chamber 35 near the first support roller 23 and the second support roller 24. A connecting gear 37 is provided in the connecting chamber 35 and passes through the opening 36. At least part of the outer wall of the rotating ring 34 is provided with transmission teeth 38, which mesh with the connecting gear 37.
[0074] A stepper motor is connected to the connecting gear 37, which drives the connecting gear 37 to rotate.
[0075] In the above embodiment, the second drive motor 32 drives the rotating shaft 25 to rotate, which in turn drives the first support roller 23 and the second support roller 24 to rotate to the protruding translation seat 22, gradually raising the gypsum board 7. Then, the connecting gear 37 is driven to rotate, which in turn drives the transmission gear 38 to rotate, and drives the rotating ring 34 to rotate. Since the gypsum board 7 is supported on the rotating ring 34, the rotation of the rotating ring 34 can drive the gypsum board 7 to move along the length or width direction.
[0076] This invention uses a lifting structure 6 to drive the weighing element 1 to rise and fall. The lifting structure 6 in this invention adopts the following preferred embodiments, such as... Figure 1 As shown, the lifting structure 6 includes a lifting frame 61 and a lifting cylinder 62 mounted on the lifting frame 61. The lifting frame 61 is located at the output end of the lifting cylinder 62. The inner wall of the support sleeve 21 is provided with a lifting groove 63. The upper end of the lifting frame 61 is slidably mounted in the lifting groove 63. The lifting platform 8 is lifted and lowered within the lifting frame 61.
[0077] The lifting cylinder 62 drives the lifting frame 61 to move upward, thereby causing the support sleeve 21 and the lifting platform 8 to move upward. During the upward or downward movement, the lifting frame 61, the support sleeve 21 and the lifting platform 8 are in a relatively stationary state.
[0078] In addition, in this invention, the lifting drive assembly 9 drives the lifting platform 8 to rise and fall, and drives the support and correction assembly 2 to rise and fall in the opposite direction, so that the lifting platform 8 moves upward to lift the plasterboard 7 and to weigh it. The lifting drive assembly 9 of this invention adopts the following preferred embodiments, such as... Figure 12 As shown, the lifting drive assembly 9 includes a connecting cavity 91 disposed within the lifting frame 61, a connecting shaft 92 disposed within the connecting cavity 91, and a drive gear 93 disposed on the connecting shaft 92; the lifting groove 63 is provided with first tooth grooves 94 at equal intervals, and the outer wall of the lifting platform 8 is provided with second tooth grooves 95 at equal intervals; the drive gear 93 is movably connected to both the first tooth grooves 94 and the second tooth grooves 95; a transmission belt 96 is disposed on the connecting shaft 92; a drive rod 97 is disposed within the lifting frame 61; the transmission belt 96 is connected to the drive rod 97; and a connecting motor 98 is disposed on the drive rod 97.
[0079] The connecting motor 98 drives the drive rod 97 to rotate, which in turn drives the transmission belt 96 to rotate, thereby driving the connecting shaft 92 to rotate and the drive gear 93 to rotate. Under the rotation of the drive gear 93, the first tooth groove 94 gradually moves down and the second tooth groove 95 gradually moves up, causing the support sleeve 21 to gradually move down and the lifting platform 8 to gradually move up. The weighing element 1 raises the gypsum board 7 and weighs the gypsum board 7.
[0080] In summary, the main implementation process of this invention is as follows:
[0081] Photoelectric sensor 10 monitors the position of gypsum board 7, gypsum board production line 4 transports gypsum board 7 to the designated weighing position, and photoelectric sensor 10 monitors the length of gypsum board 7.
[0082] The control module controls the number of weighing sensors 5 that rise and weigh based on the length of the gypsum board 7. The lifting cylinder 62 drives the lifting frame 61 to move upward, thereby causing the support sleeve 21 and the lifting platform 8 to move upward.
[0083] After moving to a certain height, the connecting motor 98 drives the drive rod 97 to rotate, which in turn drives the transmission belt 96, thereby driving the connecting shaft 92 to rotate and the drive gear 93 to rotate. The support sleeve 21 and the sliding seat 22 gradually move upwards, the lifting platform 8 gradually descends, and the sliding seat 22 gradually raises the gypsum board (e.g., Figure 1 and Figure 4 (as shown);
[0084] The first drive motor 214 drives the drive worm 212 to rotate, which in turn drives the drive worm wheel 211 to rotate, and drives the rotating rod 213 and the drive threaded rod 210 to rotate simultaneously. Under the rotation of the drive threaded rod 210, the translation seat 22 gradually moves within the sliding cavity 28, causing the gypsum board 7 at its upper end to adjust its position in the length direction.
[0085] After that, as Figure 2 and Figure 5 As shown, rotating the rotating shaft 25 drives the first support roller 23 and the second support roller 24 to rotate. During rotation, the highest points of the first support roller 23 and the second support roller 24 are gradually moved upward, gradually approaching the bottom surface of the gypsum board 7 and lifting the gypsum board 7 upward. This drives the connecting gear 37 to rotate, which in turn drives the rotating ring 34 to rotate, causing the gypsum board 7 to be corrected in position along the length or width direction. After the above position adjustment and correction, the gypsum board 7 can be aligned with the center position of the weighing area formed by the weighing sensor 5. The uniform distribution of the weighing sensor 5 can further ensure the accuracy of the final result.
[0086] After the position correction is completed, the connecting motor 98 drives the drive rod 97 to rotate, which in turn drives the transmission belt 96, thereby driving the connecting shaft 92 to rotate and the drive gear 93 to rotate. Under the rotation of the drive gear 93, the first tooth groove 94 gradually moves down, the second tooth groove 95 gradually moves up, the support sleeve 21 gradually moves down, and the lifting platform 8 and the weighing element 1 move up. The weighing element 1 gradually contacts and lifts the gypsum board 7, as shown. Figure 3 and Figure 6 As shown, the weighing element 1 weighs the supported gypsum board 7.
[0087] In addition, the present invention also provides a control method for an adaptive weighing system for gypsum board, comprising the following steps:
[0088] Step 100: Measure the length and position of plasterboard 7;
[0089] Step 200: Control the number of lifting frames 61 that rise based on the length of the gypsum board 7, and control the corresponding lifting frames 61 to rise.
[0090] Step 300: Based on the position of the gypsum board 7, the translation seat 22 is moved to adjust the position of the gypsum board 7 in the length direction;
[0091] Step 400: Control the first support roller 23 and the second support roller 24 to rotate and drive the gypsum board 7 to correct its position in the length and width directions, so as to adjust the weighing position of the weighing sensor 5 corresponding to the bottom surface of the gypsum board 7.
[0092] Step 500: Control the lifting platform 8 to descend, the weighing sensor 5 to rise, and the plasterboard 7 to approach and support the weighing sensor 5 for weighing.
