Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board conveying, and more particularly to a gypsum board turning device. Background Art

[0002] Gypsum board is a board made of building gypsum as the main raw material, mixed with a small amount of fiber materials, etc. It is a new type of decorative gypsum board flip device and a new type of interior decoration material;

[0003] In the production process of gypsum board, it is necessary to use a flipping device to flip the cut gypsum board so that the patterned surface at the bottom faces upwards, so as to facilitate further processing;

[0004] At present, the gypsum board is generally turned over by a turning machine, such as a gypsum board turning device disclosed in the utility model patent with patent number CN213170139U, in which the conveying mechanism conveys the gypsum board to the turning rod, and the driving device drives the turning rod and the connecting rod to turn upward synchronously to form a V-shaped structure until the turning rod and the connecting rod connect the gypsum board, and then the driving device drives the connecting rod to fall back to the original position, thereby realizing the turning action;

[0005] In the above-mentioned flipping method, when the gypsum board is transferred and handed over between the flipping rod and the connecting rod, the deflection movement of the gypsum board is achieved by the shift of the center of gravity of the gypsum board, and there is a lack of fixing effect on the gypsum board. When the gypsum board contacts the connecting rod, the gypsum board is easily damaged or even broken due to impact; in addition, in the process of flipping the flipping rod and the connecting rod flipping upward, the bottom edge of the gypsum board is easily squeezed by the mutual squeezing effect of the flipping rod and the folding part of the connecting rod, thereby causing damage to the bottom edge of the gypsum board, increasing the unqualified rate of the product.

[0050] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0051] See also Figure 1 The present invention discloses a gypsum board turning device, which is applied to a gypsum board conveying line. The gypsum board conveying line includes a loading conveying belt 600 and a unloading conveying belt 700 arranged in the same line;

[0052] See also Figure 2 The gypsum board flipping device is arranged between the feeding conveyor belt 600 and the unloading conveyor belt 700, and includes a support platform 100 fixedly installed on the foundation, and a flipping platform 200 is rotatably installed on the upper end of the support platform 100, and a flipping shaft 210 is arranged on the flipping platform 200; the support platform 100 is also provided with an intermittent flipping mechanism 500 for driving the flipping platform 200; two sets of clamping mechanisms 300 are centrally symmetrically arranged on the flipping platform 200;

[0053] See also Figure 3The clamping mechanism 300 includes a fixed frame 310 fixed on the turning table 200, a fixed support assembly 320 fixed on the fixed frame 310, and a movable support assembly 330 movably arranged on the fixed frame 310, and the movable support assembly 330 can be adjusted relative to the fixed support assembly 320; the fixed frame 310 is also provided with a trigger transmission assembly 340, which is used to drive the movable support assembly 330 to approach the fixed support assembly 320 when the gypsum board enters the area between the fixed support assembly 320 and the movable support assembly 330, so as to position and clamp the gypsum board;

[0054] Specifically, the support platform 100 is fixedly installed on the foundation between the loading conveyor belt 600 and the unloading conveyor belt 700, and the intermittent flipping mechanism 500 can drive the flipping platform 200 to flip intermittently in the circumferential direction relative to the support platform 100. In the initial state, the two groups of centrally symmetrical clamping mechanisms 300 on the flipping platform 200 are horizontally distributed, one group of clamping mechanisms 300 is just connected to the output end of the loading conveyor belt 600, and the movable support assembly 330 in the clamping mechanism 300 is directly above the fixed support assembly 320; and the other group of clamping mechanisms 300 is just connected to the input end of the unloading conveyor belt 700, and the movable support assembly 330 in the clamping mechanism 300 is directly below the fixed support assembly 320;

[0055] The gypsum board is pushed horizontally into the clamping mechanism 300 connected thereto by the feeding conveyor belt 600, and the lower end surface of the gypsum board just contacts the fixed support assembly 320 of the assembly clamping mechanism 300. As the gypsum board is continuously pushed in, the transmission assembly 340 is triggered to drive the movable support assembly 330 to approach the fixed support assembly 320, until the gypsum board is completely pushed into the clamping mechanism 300, and the fixed support assembly 320 just reaches the lower travel limit, thereby pressing and fixing the upper end surface of the gypsum board;

[0056] Then, the intermittent flipping mechanism 500 drives the flipping table 200 to flip 180°, so that the clamping mechanism 300 clamped with the gypsum board flips upward toward the side of the unloading conveyor belt 700, thereby realizing the flipping action of the gypsum board, and the unloaded clamping mechanism 300 flips downward toward the side of the loading conveyor belt 600, until the two sets of clamping mechanisms 300 flip to a horizontal posture again; when the clamping mechanism 300 clamped with the gypsum board is connected with the unloading conveyor belt 700, the movable support assembly 330 in the assembled clamping mechanism 300 moves away from the fixed support assembly 320 under the action of gravity, and at the same time, the gypsum board after flipping is driven to move horizontally from the clamping mechanism 300 to the unloading conveyor belt 700 by triggering the transmission assembly 340; when the unloaded clamping mechanism 300 is connected with the loading conveyor belt 600, the gypsum board on the loading conveyor belt 600 can be transferred to the assembled clamping mechanism 300 again; this reciprocating process can realize the continuous flipping operation of the gypsum board.

[0057] In one embodiment, see Figure 4 and Figure 5 The fixed support assembly 320 includes a plurality of first mounting frames 321 equidistantly distributed on the fixed frame 310, and a plurality of first rollers 322 are rotatably mounted on the first mounting frames 321; when the clamping mechanism 300 rotates to engage with the feeding conveyor belt 600, the highest point of the first roller 322 is flush with the upper belt surface of the feeding conveyor belt 600;

[0058] Specifically, the length extension direction of the first mounting frame 321 is parallel to the conveying direction of the feeding conveyor belt 600. When the feeding conveyor belt 600 conveys the gypsum board toward the clamping mechanism 300 connected thereto, since the highest point of the first roller 322 is flush with the upper belt surface of the feeding conveyor belt 600, the lower end surface of the gypsum board can be smoothly transferred from the upper belt surface of the feeding conveyor belt 600 to the first roller 322. Under the driving action of the feeding conveyor belt 600, the gypsum board is fed forward in sequence along the first rollers 322 on each of the first mounting frames 321, and the first rollers 322 are passively rotated, thereby effectively avoiding scratches on the lower end surface of the gypsum board.

[0059] See also Figure 4 and Figure 7 The movable support assembly 330 includes a sliding frame 331 slidably arranged on the fixed frame 310 and a plurality of second mounting frames 332 equidistantly distributed on the sliding frame 331, and a plurality of second rollers 333 are rotatably mounted on the second mounting frames 332; the fixed frame 310 is provided with a sliding groove 311 adapted to the sliding frame 331;

[0060] When the clamping mechanism 300 rotates to engage with the unloading conveyor belt 700, the highest point of the first roller 322 is flush with the upper belt surface of the unloading conveyor belt 700;

[0061] Specifically, during the process of the gypsum board entering the clamping mechanism 300, as the gypsum board is continuously fed, the transmission assembly 340 is triggered to drive the sliding frame 331 to slide along the sliding groove 311, thereby driving the second mounting frame 332 to move closer to the first mounting frame 321, until the gypsum board completely enters the clamping mechanism 300, at which time the second roller 333 on the second mounting frame 332 just contacts the upper end surface of the gypsum board, thereby fixing the gypsum board between the first roller 322 and the second roller 333;

[0062] Further, considering that the distance adjustment between the movable support assembly 330 and the fixed support assembly 320 is triggered by the trigger transmission assembly 340, and the trigger transmission assembly 340 needs to respond according to the motion state of the gypsum board, specifically, refer to Figure 4 and Figure 5The trigger transmission assembly 340 includes a slide bar 341 that slides through the fixed frame 310, and the end of the slide bar 341 away from the flip table 200 is connected to a push plate 342, and the push plate 342 is located between the fixed support assembly 320 and the movable support assembly 330; the end of the slide bar 341 facing the flip table 200 is connected to a push rod 343, and a connecting rod 344 is hinged between the push rod 343 and the sliding frame 331;

[0063] When the gypsum board enters the clamping mechanism 300 connected thereto under the drive of the feeding conveyor belt 600, one end of the gypsum board fed forward gradually approaches the push plate 342 until it contacts the push plate 342, thereby pushing the push plate 342 to move forward synchronously. Since the push plate 342, the slide bar 341 and the push rod 343 are an integrated fixed structure, the slide bar 341 is synchronously driven to slide relative to the fixed frame 310 toward the side of the turning table 200, thereby driving the push rod 343 to gradually move away from the fixed frame 310. Driven by the connecting rod 344, the sliding frame 331 is driven to slide downward along the slide groove 311, thereby driving each second mounting frame 332 to gradually approach the first mounting frame 321. When the gypsum board pushes the push plate 342 to the set position, it indicates that the gypsum board is delivered to the position. At this time, driven by the connecting rod 344, the second roller 333 on the second mounting frame 332 also just presses the upper end surface of the gypsum board, thereby achieving the clamping and fixing of the gypsum board.

[0064] See also Fig.10 Then, during the turning process of the turning table 200, the clamping mechanism 300 clamped with the gypsum board first turns upward to a vertical state and then turns downward to a horizontal state. During the entire turning process of the clamping mechanism 300, the gravity G on the gypsum board will always generate a component force F1 parallel to the sliding direction of the slide rod 341 and a component force F2 perpendicular to the sliding direction of the slide rod 341. The component force F1 will act on the slide rod 341 through the push plate 342, so that the push rod 343 can always pull the slide frame 331 to slide along the slide groove 311 toward the first mounting frame 321 through the connecting rod 344, so as to ensure the pressing effect of the second roller 333 on the gypsum board, so as to firmly fix the gypsum board between the first roller 322 and the second roller 333, so as to avoid the gypsum board and the clamping mechanism 300 from being separated or shifted during the turning process, and ensure the stability during the turning process.

[0065] It should be noted that during the entire flipping process of the clamping mechanism 300, no matter what the flipping angle of the clamping mechanism 300 is, the gravity G of the gypsum board will always generate a component force F1 parallel to the sliding direction of the slide rod 341 to maintain the pressing effect of the second roller 333 on the gypsum board, and the closer the clamping mechanism 300 as a whole is to a vertical state, the greater the component force F1, and thus the better the pressing effect on the gypsum board.

[0066] Furthermore, considering that when the clamping mechanism 300 rotates from the vertical state toward the unloading conveyor belt 700, the component force F2 will change from acting on the first mounting frame 321 to acting on the second mounting frame 332, and the closer the clamping mechanism 300 is to the unloading conveyor belt 700, the greater the component force F2 will be, and the smaller the component force F1 will be, in this case, the sliding frame 331 may move away from the first mounting frame 321 along the sliding groove 311, thereby losing the pressing and fixing effect on the gypsum board. It can be understood that relying solely on the component force F1 to make the second roller 333 press the gypsum board is still not reliable enough, so please refer to Figure 5 and Figure 6 The clamping mechanism 300 further includes a locking assembly 350, which includes a limiting frame 351 fixed on the fixing frame 310 and a locking pin 352 slidably disposed in the limiting frame 351, the locking pin 352 is provided with a limiting plate 353 adapted to the limiting frame 351, the fixing frame 310 is provided with a pin hole 314 adapted to the locking pin 352, and the sliding rod 341 is provided with a through hole 345 adapted to the locking pin 352;

[0067] Specifically, see Figure 8 and Fig. 9 In the initial state, the portion of the slide bar 341 without the through hole 345 blocks the pin hole 314, thereby limiting the locking pin 352 above the slide bar 341. In the process of clamping the gypsum board, as the gypsum board is continuously fed, the slide bar 341 also slides until the gypsum board is clamped in place. At this time, the through hole 345 on the slide bar 341 is just aligned with the pin hole 314, so that the locking pin 352 above the slide bar 341 passes through the through hole 345 to reach the bottom of the pin hole 314, and the locking pin 352 can be used to lock the slide bar 341. At this time, the slide bar 341 no longer slides relative to the fixing frame 310. Accordingly, the distance between the second mounting frame 332 and the first mounting frame 321 can also be kept in a locked state, thereby achieving stable clamping of the gypsum board.

[0068] It should be noted that in actual application, the friction between the locking pin 352 and the through hole 345 of the sliding rod 341 can be adjusted so that during the whole process of the clamping mechanism 300 carrying the gypsum board to flip, the locking pin 352 will not slide relative to the sliding rod 341, so that the sliding rod 341 and the fixing frame 310 can be locked. Fig.11 Only when the clamping mechanism 300 is completely turned over to connect with the unloading conveyor belt 700, that is, after the gypsum board is turned over 180°, the locking pin 352 will overcome the friction resistance with the slide bar 341 under the action of its own gravity and come out of the through hole 345 to unlock the slide bar 341, thereby causing the second roller 333 to gradually move away from the first roller 322, and at the same time drive the push plate 342 to push the gypsum board horizontally onto the unloading conveyor belt 700.

[0069] In order to improve the use effect of the locking assembly 350, a counterweight ball 354 is provided at the end of the locking pin 352 away from the pin hole 314. During the locking process, when the through hole 345 on the sliding rod 341 is connected to the pin hole 314, the locking pin 352 can more smoothly penetrate the through hole 345 and be inserted into the bottom of the pin hole 314 under the action of the gravity of the counterweight ball 354. During the unlocking process, when the gypsum board is flipped 180°, the locking pin 352 can also be smoothly pulled out of the through hole 345 under the action of the gravity of the counterweight ball 354 until the limit plate 353 on the locking pin 352 contacts the limit frame 351. At this time, the locking pin 352 is completely separated from the sliding rod 341, and the second mounting frame 332 is separated from the first mounting frame 321 under the action of its own gravity, and synchronously drives the push plate 342 to push the gypsum board out.

[0070] In addition, in the unlocking process, in order to enable the sliding frame 331 to be smoothly reset, a guide rod 312 is provided in the sliding groove 311, and the sliding frame 331 slides through the guide rod 312, and a spring 313 is provided on the movable sleeve of the guide rod 312;

[0071] Specifically, during the process of the gypsum board entering the clamping mechanism 300, as the sliding frame 331 gradually approaches the first mounting frame 321, the spring 313 is gradually compressed. After the gypsum board is flipped 180°, as the locking pin 352 disengages from the through hole 345, under the elastic force of the spring 313 and the gravity of the sliding frame 331 itself, the entire movable support assembly 330 can be driven to smoothly move away from the fixed support assembly 320.

[0072] In another embodiment, considering that after the gypsum board is turned over 180°, as the second mounting frame 332 gradually moves away from the first mounting frame 321, the overall height of the second mounting frame 332 gradually decreases, and at the same time, the push plate 342 gradually pushes the gypsum board horizontally, and the bottom surface of the gypsum board is always supported on the second roller 333. In this way, in the horizontal direction, the gypsum board gradually approaches the unloading conveyor belt 700, and in the vertical direction, the height difference between the gypsum board and the unloading conveyor belt 700 is constantly changing, which may cause a certain degree of interference between the gypsum board and the unloading conveyor belt 700, or the gypsum board is damaged or even broken when it falls on the unloading conveyor belt 700 due to the large height difference between the gypsum board and the unloading conveyor belt 700;

[0073] For the above questions, please refer to Figure 1 and Fig.12The output end of the loading conveyor belt 600 and the input end of the unloading conveyor belt 700 are both provided with a guiding mechanism 400, and the guiding mechanism 400 includes a connecting frame 410 and third mounting frames 420 equidistantly distributed on the connecting frame 410, and a plurality of third rollers 430 are rotatably mounted on the third mounting frames 420; wherein the highest point of the third roller 430 corresponding to the loading conveyor belt 600 is flush with the upper belt surface of the loading conveyor belt 600, and the highest point of the third roller 430 corresponding to the unloading conveyor belt 700 is flush with the upper belt surface of the unloading conveyor belt 700;

[0074] Specifically, when the feeding conveyor belt 600 feeds the gypsum board into the corresponding clamping mechanism 300, the first roller 322, the third roller 430 and the upper belt surface of the feeding conveyor belt 600 are at the same height, so as to ensure that the gypsum board can be smoothly pushed into the clamping mechanism 300;

[0075] When the clamping mechanism 300 clamped with the gypsum board is flipped 180° and connected to the unloading conveyor belt 700, the second mounting frame 332 can pass through the gap between the adjacent third mounting frames 420 from top to bottom in the vertical direction, thereby transitioning the gypsum board to the third roller 430 on the third mounting frame 420 on the same side, and at the same time, the gypsum board supported on the third roller 430 is pushed horizontally to the upper belt surface of the unloading conveyor belt 700 by using the push plate 342. Since the second roller 333 is separated from the gypsum board at this time, the gypsum board can move stably and horizontally along the horizontally distributed third roller 430 to the unloading conveyor belt 700, effectively avoiding interference between the gypsum board and the unloading conveyor belt 700 or damage to the gypsum board due to height difference.

[0076] It is worth noting that after the clamping mechanism 300 is flipped into place, the turning table 200 stops rotating. Therefore, when the second mounting frame 332 is away from the first mounting frame 321, the height of the push plate 342 remains unchanged, thereby ensuring that the push plate 342 pushes the gypsum board out horizontally. Moreover, after the push plate 342 pushes the gypsum board to one end and contacts the upper belt surface of the unloading conveyor belt 700, the friction force of the unloading conveyor belt 700 on the gypsum board can be used to completely pull the gypsum board out of the clamping mechanism 300. In other words, the push plate 342 only provides an initial horizontal pushing effect. Therefore, the movement stroke of the push plate 342 is not required to be too long, thereby avoiding interference between the push plate 342 and the third mounting frame 420 and affecting the normal continuous flipping of the turning table 200.

[0077] Furthermore, considering that the first mounting frame 321 and the second mounting frame 332 need not interfere with the third mounting frame 420 in the vertical direction during the continuous flipping process of the flipping table 200, this is a prerequisite for ensuring the smooth and continuous operation of the flipping device and the transfer of the gypsum board. Fig.13In the vertical direction, the first mounting frame 321 and the corresponding second mounting frame 332 overlap with each other, and the first mounting frame 321 and the corresponding second mounting frame 332 are staggered with the third mounting frame 420; in this way, during the rotation of the flip table 200, the first mounting frame 321 and the second mounting frame 332 in the same vertical plane can pass through the gap between the corresponding third mounting frames 420, thereby avoiding interference with the guiding mechanism 400.

[0078] In further embodiments, see Figure 2 and Fig.14 The intermittent flipping mechanism 500 includes a flipping motor 510 fixedly mounted on the support platform 100, a turntable 520 fixedly connected to the output shaft of the flipping motor 510, and an intermittent flipping block 530 fixedly connected to the flipping shaft 210; a raised arc-shaped guide strip 523 is provided on the outer circumference of the turntable 520, and a notch is formed between the two ends of the arc-shaped guide strip 523, and a first lever 521 and a second lever 522 are respectively provided on the turntable 520, and the first lever 521 and the second lever 522 are located at the notch and the first lever 521 and the second lever 522 are on the same circumference; arc-shaped surfaces 533 adapted to the arc-shaped guide strip 523 are symmetrically provided on both sides of the intermittent flipping block 530, and the first arc-shaped groove 531 and the second arc-shaped groove 532 are symmetrically provided on the two sides of the intermittent flipping block 530 adjacent to the arc-shaped surface 533;

[0079] Specifically, Fig.14 For reference, the turning motor 510 drives the turntable 520 to rotate clockwise. First, the first lever 521 enters the first arc groove 531 on one side. At this time, the gap will not restrict the intermittent turning block 530. As the turntable 520 rotates, the intermittent turning block 530 can be driven to rotate synchronously through the first lever 521, thereby realizing the turning of the turning table 200. During the rotation of the intermittent turning block 530, the second lever 522 also successively enters the corresponding second arc groove 532, and the first lever 521 successively moves out of the corresponding first arc groove 531 until the turning table 200 is turned. The intermittent flip block 530 flips 180°. When the first lever 521 and the second lever 522 are both moved out, the arc surface 533 on one side just fits against the inner wall of the arc guide strip 523. Thus, under the restriction of the arc guide strip 523, the intermittent flip block 530 no longer rotates until the turntable 520 rotates 360°. Then, the first lever 521 enters the first arc groove 531 on the other side again, thereby continuing to drive the intermittent flip block 530 to flip 180°. This reciprocating process can drive the intermittent flip block 530 to flip intermittently through the continuously rotating turntable 520.

[0080] It should be noted that in actual applications, the rotation cycle of the turntable 520 can be set so that the flipping frequency of the flipping table 200 meets actual needs, that is, when the gypsum board is loaded and unloaded, the intermittent flipping block 530 performs a flipping action, and during the loading and unloading process of the gypsum board, the intermittent flipping block 530 does not flip.

[0081] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
