Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, in particular to a gypsum board sheet assembly method and device. Background Art

[0002] The gypsum board production line is a special equipment for producing gypsum boards, which consists of a raw material supply system, a board making system, a conveying system, a transverse system, a drying system, a board discharging system, and a trimming system. After trimming, the gypsum boards need to be stacked neatly. When stacking gypsum boards, in order to improve the stacking efficiency and make the final stacking more neat, two gypsum boards are often stacked back to back. The equipment used in the stacking process is a laminating machine.

[0003] For example, a Chinese invention patent with announcement number CN105858232A discloses a gypsum board assembling machine and a assembling method, in which a flip fork and a connecting board fork are symmetrically arranged on two sets of rotating mechanisms. The trimmed gypsum board is received by the flip fork and flipped, and the original gypsum board on the board output fork is also rotated by the board output fork and moved closer to the flip fork. The flip fork releases the flipped gypsum board and stacks it back to back with the gypsum board on the connecting board fork.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 9 , the present invention provides a technical solution:

[0036] like Figure 1As shown, a gypsum board assembly device includes a frame module 100, on which two flip modules 200 are arranged. The two flip modules 200 drive the gypsum boards to flip and realize the assembly of the two gypsum boards. The two flip modules 200 are both provided with an adjustment module 300 for adjusting the position of the gypsum boards. As the flip modules 200 drive the gypsum boards to flip, the adjustment module 300 adjusts the position of the gypsum boards so that the positions of the two gypsum boards correspond to each other, thereby avoiding the phenomenon that the two gypsum boards are misaligned when the gypsum boards are assembled. One of the flip modules 200 is provided with a pushing module 400 for pushing the gypsum boards after the assembly is completed. Under the action of the pushing module 400, the two gypsum boards after the assembly can be squeezed to avoid the gypsum boards from being misaligned under the action of gravity. The rack module 100 is provided with two auxiliary units 500 for pressing the gypsum boards on the flip module 200 respectively. Under the action of the auxiliary units 500, the gypsum boards can be squeezed during the flipping process, thereby avoiding the gypsum boards from falling off due to excessive flipping angles.

[0037] like Figure 2 As shown, the frame module 100 includes a frame 101. The frame 101 serves as the basic supporting structure of the entire device and is welded with high-strength steel. It has sufficient rigidity and stability and can withstand various forces in the process of sheet assembly. A conveying channel 102 is arranged on the top of the frame 101. Two partitions 103 are arranged in the conveying channel 102. The flip module 200 is located between the two partitions 103. A plurality of transmission rollers 104 are rotatably connected between the partitions 103 and the side walls of the conveying channel 102 through a rotating shaft. The surface of the transmission roller 104 is made of rubber material, which can not only ensure effective support and transportation of the gypsum board, but also avoid scratches on the surface of the gypsum board. An installation box 105 is arranged in the middle of the lower surface of the conveying channel 102 for installing some power and transmission components to protect and hide the device, making the appearance of the device more tidy and convenient for maintenance and inspection.

[0038] like Figure 4As shown, the flip module 200 includes a flip box 201, one side of the flip box 201 is rotatably connected with a connecting shaft 202, ensuring that the flip box 201 can stably rotate around the connecting shaft 202, the connecting shaft 202 is fixedly connected to the partition 103, a driving plate 203 is arranged at the bottom of one side of the flip box 201, a fixing seat 204 is arranged at the bottom of the inner wall of the installation box 105, and a hydraulic cylinder 205 is rotatably connected between the fixing seat 204 and the driving plate 203, and the retractable movement of the hydraulic cylinder 205 can accurately control the flip box 201. Flipping angle and speed, two through grooves 206 are provided on the upper surface of the flip box 201, which are convenient for the subsequent pushing module 400 to operate the gypsum board. A baffle 207 is inserted on one side of the upper surface of the flip box 201, and a plurality of ball bearings 208 are provided on the abutting sides of the baffle 207 and the gypsum board. During the entry and flipping process of the gypsum board, the baffle 207 plays a limiting role, and the ball bearings 208 reduce the friction between the gypsum board and the baffle 207 to prevent the surface of the gypsum board from being damaged, so as to facilitate the subsequent adjustment module 300 to adjust the position of the gypsum board.

[0039] like Figure 8 As shown, the adjustment module 300 includes a driving member and two moving plates 307. The moving plates 307 are slidably connected to the bottom of the inner wall of the flip box 201. A high-precision guide rail slider structure is used between the moving plates 307 and the inner wall of the flip box 201 to ensure the stability and accuracy of the movement of the moving plates 307. The driving member is used to drive the moving plates 307 to move. Transmission arms 306 are provided on the opposite sides of the moving plates 307. Adjustment plates 308 are sleeved on the transmission arms 306. Springs 309 are provided between the adjustment plates 308 and the moving plates 307. The springs 309 provide elastic buffering and adaptive adjustment capabilities. The top of the adjustment plates 308 extends out of the flip box 201 and is plugged with an adjustment block 310. When the adjustment block 310 contacts the gypsum board, it can automatically adjust the thrust and position of the gypsum board under the action of the springs 309 according to the position and shape changes of the gypsum board, thereby ensuring that the two gypsum boards always maintain the correct relative position during the flipping process to avoid misalignment.

[0040] Furthermore, the driving member includes a transmission shaft 301, which is rotatably connected to the inner wall of the flip box 201. Bevel gears 302 are provided on the end of the transmission shaft 301 and the connecting shaft 202. The two bevel gears 302 are meshingly connected. The two bevel gears 302 have different specifications, thereby realizing power transmission and speed change. A driving disk 303 is provided on the transmission shaft 301. The driving disk 303 is rotatably connected to a push arm 305 through two shafts 304. The ends of the two push arms 305 are rotatably connected to the transmission arms 306, respectively, thereby converting the rotation of the transmission shaft 301 into a linear motion of the transmission arm 306, thereby driving the movable plate 307 to move.

[0041] like Figure 5-Figure 7 As shown, the pushing module 400 includes a motor 401. The motor 401 adopts a high-performance servo motor, which can accurately control the speed and torque. The motor 401 is arranged inside the flip box 201. The output shaft of the motor 401 is provided with two driving rods 402. Two double-threaded screw rods 403 are rotatably connected in the flip box 201. The two double-threaded screw rods 403 have different pitches, which realize different transmission speeds and displacements. One end of the double-threaded screw rod 403 and the driving rod 402 is provided with a bevel gear 404. The adjacent two Two bevel gears 404 are meshed and connected, and two moving seats 405 are threadedly connected to the double-threaded lead screw 403. The top of the moving seat 405 is rotatably connected to a push plate 406. The ends of the four push plates 406 are rotatably connected to two bottom plates 407. Push plates 408 are arranged above the bottom plates 407. During the resetting process of the gypsum board after the gypsum board is assembled, the motor 401 is started to drive the various components to move, so that the push plates 408 squeeze the gypsum board after the gypsum board is assembled upward, and the two push plates 408 are respectively located in the two through grooves 206.

[0042] Furthermore, a plurality of springs 409 are provided between the pushing plate 408 and the bottom plate 407, two spheres 410 are provided on the lower surface of the pushing plate 408, the central axes of the two spheres 410 are parallel and located in the same vertical plane, and a connecting seat 411 is provided on the upper surface of the bottom plate 407, and the connecting seat 411 is respectively connected with the sphere 410, so that the pushing plate 408 can more flexibly adapt to the surface shape and position changes of the gypsum board during the rising process, thereby further improving the extrusion effect and stability.

[0043] like Fig. 9 As shown, the auxiliary unit 500 includes a cylinder 501, a mounting seat 502 is provided at the output end of the cylinder 501, a fixing block 503 is provided on the top of the mounting seat 502, the fixing block 503 is rotatably connected to an auxiliary shaft 504, an auxiliary arm 508 is provided at one end of the auxiliary shaft 504, the end of the auxiliary arm 508 is rotatably connected to an auxiliary pressure plate 509, and the end of the auxiliary arm 508 and the upper surface of the mounting seat 502 are both provided with hanging rings 510, and the two hanging rings 510 are connected to a spring three 512 through two connecting hooks 511.

[0044] Furthermore, a plurality of limiting grooves 505 are formed on one side of the fixing block 503 , wherein a limiting column 506 is inserted into one of the limiting grooves 505 , and a limiting connecting rod 507 corresponding to the limiting column 506 is disposed at the other end of the auxiliary shaft 504 .

[0045] Specifically, during the turning process of the gypsum board, when the turning angle reaches a certain range of 30 to 60 degrees, the auxiliary pressing plate 509 fits with the surface of the gypsum board. Since the auxiliary pressing plate 509 is rotatably connected to the auxiliary arm 508, the auxiliary pressing plate 509 can completely fit with the gypsum board. As the gypsum board continues to turn over, under the elastic force of the spring three 512, the auxiliary arm 508 drives the auxiliary pressing plate 509 to squeeze the gypsum board, thereby preventing the gypsum board from falling off. It should be noted that the auxiliary pressing plate 509 is a thin sheet structure, so that the two gypsum boards can be as close as possible when they are combined. After turning to the specified angle, the cylinder 501 works to push the mounting seat 502, the fixing block 503 and the auxiliary arm 508 to start moving, so that the auxiliary pressure plate 509 is separated from the gypsum board, and the two gypsum boards complete the joining work. Under the elastic force of the spring three 512, the auxiliary pressure plate 509 is reset. When the two flip modules 200 are reset, the cylinder 501 works again to reset the auxiliary pressure plate 509. Through the cooperation of the limit column 506 and the limit groove 505, the rotation range of the auxiliary shaft 504 can be limited, thereby accurately controlling the extrusion position of the auxiliary pressure plate 509, and effectively preventing the gypsum board from falling off due to excessive flipping angle.

[0046] like Figure 3 As shown, a gypsum board assembling method based on the gypsum board assembling device comprises the following specific steps:

[0047] The staff installs the sheet-closing device between the two conveyors 600, and delivers the gypsum boards to be processed to the two turnover modules 200 through the two conveyors 600;

[0048] The flip module 200 is started. As the flip module 200 drives the gypsum board to flip, the adjustment module 300 adjusts the position of the gypsum board so that the positions of the two gypsum boards correspond to each other. When the flip module 200 drives the gypsum board to flip to 30-60 degrees, the auxiliary unit 500 squeezes the gypsum board to prevent the gypsum board from falling off.

[0049] When one of the flip modules 200 drives the gypsum board to flip to 90-120 degrees, the other flip module 200 drives the gypsum board to flip to 60-90 degrees. At this time, the partial structures of the two adjustment modules 300 are offset, and then the auxiliary unit 500 is separated from the gypsum board, and the two gypsum boards are attached.

[0050] Another flipping module 200 drives the two gypsum boards to reset. During this process, the pushing module 400 works to squeeze the two gypsum boards to avoid misalignment of the two gypsum boards. As the angle between the two gypsum boards and the horizontal plane gradually decreases, one of the flipping modules 200 and the pushing module 400 is reset, and the two gypsum boards work completely together.

[0051] The working process of this embodiment is as follows: the conveyor 600 of the production line is started, and the gypsum board to be processed is conveyed to the conveying channel 102 of the frame module 100. The gypsum board moves toward the flip module 200 under the action of the driving roller 104. When the gypsum board reaches the top of the flip module 200, the baffle 207 initially limits it so that the gypsum board can be stably parked on the flip box 201. At this time, the gypsum board is in an initial horizontal state and is ready for flipping and closing operations. The flip module 200 is started, and the hydraulic cylinder 205 starts to work. Its extension drives the driving plate 203 to move, thereby causing the flip box 201 to rotate. 1 rotates around the connecting shaft 202. During the flipping process, the rotation of the connecting shaft 202 drives the transmission shaft 301 to rotate through the meshing transmission of the bevel gear 1 302. The transmission shaft 301 then drives the moving plate 307 to move through the push arm 305 and the transmission arm 306. The moving plate 307 drives the adjustment plate 308 and the adjustment block 310 to adjust the position of the gypsum board in real time. When the flip module 200 drives the gypsum board to flip to 30-60 degrees, the auxiliary pressing plate 509 fits with the surface of the gypsum board to ensure that the extrusion position and force of the auxiliary pressing plate 509 on the gypsum board are stable. When the two gypsum boards are flipped to the specified position, The cylinder 501 works to push the mounting seat 502, the fixing block 503 and the auxiliary arm 508 to start moving, so that the auxiliary pressing plate 509 is separated from the gypsum board. The motor 401 is started, and its output shaft drives the driving rod 402 to rotate. The double-threaded screw 403 is rotated through the meshing transmission of the bevel gear 404. The moving seat 405 on the double-threaded screw 403 drives the push plate 406 to move. The push plate 406 pushes the bottom plate 407 to rise. The bottom plate 407 cooperates with the connecting seat 411 and the ball 410 to make the push plate 408 squeeze the gypsum board after the sheet is assembled upward. The other flip module 200 drives the two The gypsum boards after joining begin to reset. As the angle between the two gypsum boards and the horizontal plane gradually decreases, when the gypsum boards are close to a horizontal state, one of the flip modules 200 and the pushing module 400 resets, and the hydraulic cylinder 205 works in the reverse direction to return the flip box 201 to the initial horizontal position, and the motor 401 reverses to return the components of the pushing module 400 to the initial state. At this time, the two gypsum boards have completed the entire joining operation. The gypsum boards after joining can be transported to subsequent processing or storage links under the action of the transmission roller 104 of the conveying channel 102, and the entire joining device is ready for the next round of gypsum board joining operations.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
