Description

Technical Field

[0001] This invention relates to the field of gypsum board processing technology, specifically to a self-correcting gypsum board facing paper scoring system. Background Technology

[0002] During the gypsum board molding process, a scoring machine is needed to score the gypsum board facing paper. To produce gypsum boards of different thicknesses, the scoring positions need to correspond to the scoring positions of the facing paper. Therefore, the scoring machine spacing needs to be adjusted to adjust the scoring positions of the facing paper. Grooves are scored on the gypsum board paper using a circular knife or pressure roller mechanism. The edges of the gypsum board are then straightened using a forming knife and an edge trimmer. Generally, the angle between the top and bottom edges of half of the gypsum board is 90 degrees. Since the facing paper is 0.2-0.3mm thick, the scoring accuracy requirements on the facing paper are relatively high. Deep scoring can easily cause the paper surface to tear, while shallow scoring can result in the edge shape being rounded after passing through the edge trimmer and forming knife, failing to achieve the ideal angle.

[0003] To facilitate the circular blade's marking on the gypsum board facing paper, a deep groove is engraved on the paper shaft below the blade. This groove, in conjunction with the blade, marks the gypsum board facing paper portion above it. However, the marking position of the marking machine needs adjustment depending on the thickness and width of the gypsum board. Since the position of the deep groove on the paper shaft is fixed, the blade deviates from the groove during adjustment, affecting the marking process. Current methods solve this problem by connecting the blade and paper shaft together for movement. However, during the transport of the facing paper, static friction causes a slight change in the groove's position over time, leading to the blade moving to the edge or exceeding the groove's position, resulting in blade wear and high-speed motor damage, ultimately preventing marking at the groove's location.

[0004] Therefore, the existing technology has the following technical problems: long-term use causes the circular blade to shift from the deep groove position on the paper shaft, resulting in wear of the circular blade and damage to the high-speed motor, and a decrease in the quality of the engraving. Summary of the Invention

[0005] To address this issue, the present invention provides a self-correcting gypsum board facing paper marking system, which effectively solves the problem in the prior art where long-term use leads to misalignment between the circular blade and the deep groove on the paper shaft, resulting in wear of the circular blade and damage to the high-speed motor, thus reducing the marking quality.

Detailed Implementation

[0044] 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.

[0045] like Figure 1 As shown, the present invention provides a self-correcting gypsum board facing paper scoring system, which includes a fixed scoring structure 1, a follow-up limiting shaft 2, a connecting linkage 3, and a correction and alignment structure 4.

[0046] The fixed scoring structure 1 is used to receive the gypsum board facing paper to be scored and adjust the position of the scoring head according to the width of the gypsum board to adjust the scoring position on the gypsum board facing paper.

[0047] The follower limiting shaft 2 is located below the fixed scoring structure 1, and the gypsum board facing paper is located above the follower limiting shaft 2. The follower limiting shaft 2 is movably provided with a scoring limiting groove seat 5, and a scoring deep groove 6 is formed in the scoring limiting groove seat 5. The follower limiting shaft 2 can adjust the position of the scoring limiting groove seat 5 according to the position of the scoring head of the fixed scoring structure 1 so that the scoring deep groove 6 is aligned with the scoring position on the gypsum board facing paper.

[0048] The linkage component 3 is set between the fixed scoring structure 1 and the follower limiting shaft 2. The linkage component 3 is used to drive the scoring limiting groove seat 5 on the follower limiting shaft 2 to move synchronously with the same displacement when the fixed scoring structure 1 makes an adjustment, so that the scoring groove 6 is aligned with the scoring position of the gypsum board facing paper.

[0049] The alignment structure 4 is set on the follower limiting shaft 2. The alignment structure 4 is used to measure the horizontal position of the scoring groove 6 and the scoring position of the gypsum board facing paper. When the horizontal position of the scoring groove 6 and the scoring position of the gypsum board is misaligned, the relative position of the scoring groove 6 and the scoring head of the fixed scoring structure 1 is adjusted, and the horizontal position of the scoring limiting groove seat 5 is periodically corrected so that the position of the inner groove of the scoring limiting groove seat 5 is directly below the scoring position of the gypsum board facing paper.

[0050] In this embodiment of the invention, a follower limiting shaft 2 is provided. The position of the scoring limiting groove seat 5 is adjusted according to the position of the scoring head of the fixed scoring structure 1 so that the scoring groove 6 is aligned with the scoring position of the gypsum board. The relative position of the scoring groove 6 and the scoring head of the fixed scoring structure 1 is adjusted by the alignment correction structure 4, and the horizontal position of the scoring limiting groove seat 5 is periodically corrected so that the position of the scoring groove 6 is directly below the scoring position of the gypsum board. The method of adjusting first and then correcting further ensures the alignment of the scoring position with the scoring groove 6, and avoids the scoring head from moving to the edge of the scoring groove 6 or exceeding the position of the scoring groove 6, which would cause wear of the scoring head and damage to the motor.

[0051] In this invention, the follower limiting shaft 2 can adjust the position of the scoring limiting groove seat 5 according to the position of the scoring head of the fixed scoring structure 1, so that the scoring groove 6 is aligned with the scoring position on the gypsum board facing paper. The follower limiting shaft 2 in this invention adopts the following preferred embodiment: the follower limiting shaft 2 includes a frame 21, a fixed guide rail 22 disposed on the frame 21, a mounting bracket 23 disposed on the fixed scoring structure 1, a connecting shaft seat 24 slidably disposed on the fixed guide rail 22, and a slide seat 25 disposed at the bottom of the connecting shaft seat 24.

[0052] The connecting shaft seat 24 is slidably mounted on the fixed guide rail 22 via the slide seat 25. The mounting bracket 23 is provided with a fixed cylinder seat 26. One end of the connecting shaft seat 24 slides inside the fixed cylinder seat 26, and the other end of the connecting shaft seat 24 extends outside the fixed cylinder seat 26. A sliding groove 27 is provided inside the connecting shaft seat 24, and a grooved limiting seat 5 is movably mounted inside the sliding groove 27.

[0053] In the above embodiment, the connecting shaft seat 24 can move horizontally under the drive of the fixed scoring structure 1. The mounting bracket 23 is connected to the fixed scoring structure 1 through the linkage 3, so that the fixed scoring structure 1 moves the connecting shaft seat 24 together while adjusting its position, thereby keeping the connecting shaft seat 24 and the scoring head of the fixed scoring structure 1 in a relatively stationary state during the adjustment of the position of the fixed scoring structure 1.

[0054] In this invention, the fixed scoring structure 1 receives the plasterboard facing paper to be scored and adjusts the position of the scoring head according to the width of the plasterboard to adjust the scoring position on the plasterboard facing paper. The fixed scoring structure 1 of this invention adopts the following preferred embodiments, such as... Figure 1 and Figure 2 As shown, the fixed scoring structure 1 includes a slide rail 11 mounted on the frame 21, a linear slide 12 slidably mounted on the slide rail 11, a drive chamber 13 mounted on the linear slide 12, and a scoring wheel 14 mounted outside the drive chamber 13; a drive motor 15 is mounted on the drive chamber 13, and the scoring wheel 14 is mounted on the output end of the drive motor 15.

[0055] In the above embodiment, the drive motor 15 drives the scoring wheel 14 to rotate at high speed to score the plasterboard facing paper. In addition, the linear slide 12 can slide on the slide rail 11, mainly moving in the horizontal direction, thereby adjusting the horizontal position of the scoring wheel 14 to be flush with the position to be scored on the plasterboard facing paper.

[0056] In order to drive the linear slide 12 to slide on the slide rail 11, the present invention also makes the following design: an adjustment motor 16 is installed on the frame 21, and a threaded screw 17 is provided at the end of the adjustment motor 16, which is threadedly connected to the linear slide 12.

[0057] The adjusting motor 16 drives the threaded screw 17 to rotate. Under the rotation of the threaded screw 17, the linear slide 12 slides on the slide rail 11, thereby driving the scoring wheel 14 to move in the horizontal direction. At the same time, the mounting bracket 23 and the connecting connector 3 drive the connecting shaft seat 24 to move, so that the scoring groove 6 and the scoring wheel 14 are adjusted to be flush with the scoring position on the plasterboard facing paper.

[0058] In this invention, the linkage component 3 is used to drive the scoring limiting groove seat 5 on the follower limiting shaft 2 to move synchronously with the same displacement when the fixed scoring structure 1 is adjusted, so that the scoring groove 6 is horizontally aligned with the scoring position of the gypsum board facing paper. The linkage component 3 of this invention adopts the following preferred embodiment, such as... Figure 1 As shown, the linkage component 3 includes a connecting frame 31 disposed on the linear slide 12 and a fixing bolt 32 disposed between the connecting frame 31 and the mounting frame 23; the mounting frame 23 is fixed to the connecting frame 31 by the fixing bolt 32.

[0059] In the above embodiment, the linear slide 12 moves by moving the connecting shaft seat 24 through the mounting bracket 23 and the connecting bracket 31, and the connecting bracket 31 and the mounting bracket 23 are installed together by fixing bolts.

[0060] In this invention, the alignment structure 4 measures the horizontal position of the scoring groove 6 and the scoring position of the gypsum board facing paper. When the horizontal position of the scoring groove 6 and the scoring position of the gypsum board is misaligned, the relative position of the scoring groove 6 and the scoring head of the fixed scoring structure 1 is adjusted, and the horizontal position of the scoring limiting groove seat 5 is periodically corrected so that the position of the inner groove of the scoring limiting groove seat 5 is directly below the scoring position of the gypsum board facing paper.

[0061] The calibration alignment structure 4 of the present invention adopts the following preferred embodiments, such as... Figure 2 As shown, the alignment structure 4 includes a alignment motor 41 mounted on a linear slide 12, a first adjusting threaded rod 42 mounted on the output end of the alignment motor 41, a first transmission gear 43 mounted on the first adjusting threaded rod 42, and a first limiting bolt 44 mounted on the first adjusting threaded rod 42. The first adjusting threaded rod 42 is mounted through the mounting frame 23 and is threadedly connected to the drive compartment 13. The first adjusting threaded rod 42 is rotatably mounted on the mounting frame 23 via the first limiting bolt 44.

[0062] In the above embodiment, the correction motor 41 drives the first adjusting threaded rod 42 to rotate, and the rotation of the first adjusting threaded rod 42 drives the drive chamber 13 to move, thereby driving the etched wheel 14 to move and adjust its horizontal position.

[0063] The unilateral adjustment efficiency of the scoring wheel 14 is low. In the initial adjustment process, the scoring wheel 14 and the scoring groove 6 are adjusted together to ensure that the scoring wheel 14 is initially aligned. To move the scoring groove 6 along with the scoring wheel 14 during adjustment, the present invention also incorporates the following design: a first locking shaft 45 is provided on the mounting frame 23, and a second locking shaft 46 is rotatably provided inside the connecting frame 31. Both the first locking shaft 45 and the second locking shaft 46 have second limiting bolts 47 at their ends. The first locking shaft 45 is rotatably mounted on the mounting frame 23 via the second limiting bolts 47. 3. The second locking shaft 46 is rotatably mounted on the connecting frame 31 via the second limiting bolt 47; the first locking shaft 45 is rotatably mounted with a second transmission gear 48, the first transmission gear 43 meshes with the second transmission gear 48; the second locking shaft 46 is rotatably mounted with a third transmission gear 49, the third transmission gear 49 meshes with the second transmission gear 48; the end of the second locking shaft 46 is provided with a threaded shaft 410; the connecting frame 31 is provided with a connecting groove 411; the threaded shaft 410 passes through the connecting groove 411 and enters the fixed cylinder seat 26; the end of the threaded shaft 410 is threadedly connected to the connecting shaft seat 24.

[0064] In the above embodiment, when the first adjusting threaded rod 42 rotates, it drives the first transmission gear 43 to rotate. The first transmission gear 43 drives the second transmission gear 48 to rotate, thereby driving the third transmission gear 49 to rotate. The rotation of the third transmission gear 49 drives the threaded shaft 410 to rotate. Since the end of the threaded shaft 410 is threadedly connected to the connecting shaft seat 24, the connecting shaft seat 24 gradually moves under the limiting effect of the rotation of the threaded shaft 410 and the sliding seat 25.

[0065] In this configuration, the first adjusting threaded rod 42 and the threaded shaft 410 have opposite thread directions. When the first adjusting threaded rod 42 rotates clockwise, it drives the etched wheel 14 to move forward, which in turn drives the first transmission gear 43 to rotate clockwise, the second transmission gear 48 to rotate counterclockwise, and the third transmission gear 49 to rotate clockwise. The threaded shaft 410 rotates clockwise, which drives the connecting shaft seat 24 to move backward. Therefore, in this case, the adjustment processes of the connecting shaft seat 24 and the etched wheel 14 are opposite. When the horizontal positions of the etched wheel 14 and the etched groove 6 do not correspond, clockwise or counterclockwise rotation can make the horizontal positions of the etched wheel 14 and the etched groove 6 gradually approach and coincide.

[0066] Assuming the threads of the first adjusting threaded rod 42 and the threaded shaft 410 are in the same direction, when the first adjusting threaded rod 42 rotates clockwise, it drives the etched wheel 14 to move forward, which in turn drives the first transmission gear 43 to rotate clockwise, the second transmission gear 48 to rotate counterclockwise, and the third transmission gear 49 to rotate clockwise. The threaded shaft 410 rotates clockwise, which drives the connecting shaft seat 24 to move forward. Therefore, in this case, the movement of the connecting shaft seat 24 and the etched wheel 14 during the adjustment process is the same, but the speeds during the movement are different, with one moving faster. Therefore, in this case, clockwise or counterclockwise rotation can make the horizontal positions of the etched wheel 14 and the etched groove 6 gradually approach and gradually move away to find the position where they coincide, so that the horizontal positions of the etched wheel 14 and the etched groove 6 coincide.

[0067] The above process involves adjusting the relative horizontal positions of the scoring wheel 14 and the scoring groove 6 during the preparation stage before the gypsum board facing paper is transported. The alignment structure 4 can also correct the position of the scoring groove 6 during the transportation of the gypsum board facing paper. The present invention is specifically designed as follows: Figure 3 and Figure 4 As shown, a first connecting cylinder 412 is provided in the slide groove 27, and a second connecting cylinder 413 is sleeved on the first connecting cylinder 412. A connecting spring 414 is provided in the first connecting cylinder 412 and the second connecting cylinder 413. One end of the connecting spring 414 is connected to the first connecting cylinder 412 and the other end is connected to the second connecting cylinder 413. The end of the second connecting cylinder 413 is connected to the inner wall of the slide groove 27, and the end of the first connecting cylinder 412 abuts against the engraved limiting groove seat 5.

[0068] The above-mentioned push of the scoring limiting groove seat 5 to the right by the first connecting cylinder 412 and the second connecting cylinder 413 ensures that the scoring limiting groove seat 5 is always subjected to a rightward force. Additionally, an adjustment structure is provided on the right side of the scoring limiting groove seat 5 to adjust its position within the slide groove 27, as detailed below. Figure 3 and Figure 5 As shown, an adjusting disc 415 is provided in the slide groove 27 on the side away from the first connecting cylinder 412 and the second connecting cylinder 413. An adjusting shaft 416 is provided on the adjusting disc 415, and a connecting motor 417 is provided on the adjusting shaft 416. The adjusting shaft 416 is connected to the output end of the connecting motor 417. The adjusting shaft 416 is located on the adjusting disc 415 away from the center, and the end of the adjusting disc 415 abuts against the side wall of the etched limiting groove seat 5.

[0069] In order to limit the sliding process of the scoring limiting groove seat 5, a limiting groove 418 is provided in the sliding groove 27, and a limiting block 419 is provided at the bottom of the scoring limiting groove seat 5, and the limiting block 419 is slidably disposed in the limiting groove 418.

[0070] In the above embodiment, the connecting motor 417 drives the adjusting shaft 416 to rotate, thereby driving the adjusting disc 415 to rotate. Since the adjusting shaft 416 is centrifugally set, the horizontal position of the adjusting shaft 416 is fixed. During the rotation of the adjusting disc 415, the distance from the edge of the adjusting disc 415 that abuts against the side of the scoring limiting groove seat 5 to the adjusting shaft 416 changes. Under the rightward force of the first connecting cylinder 412 and the second connecting cylinder 413 on the scoring limiting groove seat 5, the scoring limiting groove seat 5 always abuts against the edge of the adjusting disc 415. Therefore, the position of the scoring limiting groove seat 5 changes when the adjusting disc 415 rotates, thereby realizing the position correction of the scoring limiting groove seat 5.

[0071] In addition, the alignment structure 4 of the present invention has the function of measuring the horizontal position of the groove 6 and the scribing position of the plasterboard facing paper. A corresponding photoelectric distance sensor can be set to determine the horizontal position of the groove 6 and the scribing wheel 14, which also facilitates subsequent position adjustment and correction.

[0072] In summary, the main implementation process of this invention is as follows:

[0073] The etched positions of the plasterboard facing paper are preset, the horizontal positions of the etched groove 6 and the etched wheel 14 are measured, and the relative positions of the etched groove 6 and the etched wheel 14 are adjusted according to the measured horizontal positions of the etched groove 6 and the etched wheel 14.

[0074] The correction motor 41 drives the first adjusting threaded rod 42 to rotate. Under the rotation of the first adjusting threaded rod 42, the drive chamber 13 moves, thereby moving the scoring wheel 14 to adjust its horizontal position. When the first adjusting threaded rod 42 rotates, it drives the first transmission gear 43 to rotate. The first transmission gear 43 drives the second transmission gear 48 to rotate, thereby driving the third transmission gear 49 to rotate. The rotation of the third transmission gear 49 drives the threaded shaft 410 to rotate. Since the end of the threaded shaft 410 is threadedly connected to the connecting shaft seat 24, under the rotation of the threaded shaft 410 and the limiting effect of the slide 25, the connecting shaft seat 24 gradually moves. The connecting shaft seat 24 and the scoring wheel 14 are simultaneously adjusted in position so that the scoring groove 6 and the scoring wheel 14 are aligned in the horizontal position.

[0075] The adjusting motor 16 drives the threaded screw 17 to rotate. Under the rotation of the threaded screw 17, the linear slide 12 slides on the slide rail 11, thereby driving the scoring wheel 14 to move horizontally. At the same time, the mounting bracket 23 and the connecting connector 3 drive the connecting shaft seat 24 to move, so that the scoring groove 6 and the scoring wheel 14 are adjusted to be flush with the position to be scored on the gypsum board facing paper. At this time, the scoring groove 6, the scoring wheel 14 and the position to be scored on the gypsum board facing paper are in the same horizontal position.

[0076] The gypsum board facing paper is transported by a drive motor 15, which drives the scoring wheel 14 to rotate at high speed and score the gypsum board facing paper at the scoring groove 6.

[0077] The horizontal position of the scoring groove 6 and the scoring wheel 14 is checked periodically. If the check is inconsistent, the drive motor 417 drives the adjustment shaft 416 to rotate, thereby driving the adjustment disc 415 to rotate. Under the rightward force of the first connecting cylinder 412 and the second connecting cylinder 413 on the scoring limiting groove seat 5, the scoring limiting groove seat 5 always abuts against the edge of the adjustment disc 415. The position of the scoring limiting groove seat 5 changes when the adjustment disc 415 rotates, thus correcting the position of the scoring groove 6.

[0078] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
