Description

Technical Field

[0001] The present invention belongs to the technical field of gypsum board detection, and in particular, relates to a gypsum board strength detection device. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. Gypsum board is widely used in various buildings such as residences, office buildings, shops, hotels and industrial plants, such as interior partitions, wall coverings, ceilings, sound-absorbing panels, ground base panels and various decorative panels.

[0003] Gypsum boards are usually produced in batches, and quality inspections, including strength inspections, are required before leaving the factory. Usually, some samples are taken from the same batch of gypsum boards for testing. The testing method is to test multiple gypsum board samples one by one through testing equipment. Before testing, the position of the gypsum board needs to be adjusted so that the force points are consistent during testing to avoid large test errors due to different positions. Existing gypsum board strength testing equipment usually requires manual calibration of the position of the gypsum board, which is time-consuming and labor-intensive. Moreover, when there are many samples to be tested, since each gypsum board needs to be calibrated before testing, the interval time required for multiple sample testing is long, which will affect the efficiency of the test.

[0024] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0025] See also Figure 1The present invention is a gypsum board strength testing device, comprising a gypsum frame 1, a conveying mechanism 2, a lifting mechanism 3, a pressure mechanism 4 and a cleaning mechanism 5. The opening of the gypsum frame 1 is downward and two symmetrically arranged on the left and right. The pressure mechanism 4 is located above the conveying mechanism 2, and the cleaning mechanism 5 is located between the pressure mechanism 4 and the conveying mechanism 2. The two gypsum frames 1 are respectively provided with a lifting mechanism 3, and the lifting mechanism 3 is arranged on the front and rear side walls of the gypsum frame 1. The lifting mechanism 3 is connected with the conveying mechanism 2 through an external conveying device, and multiple gypsum board samples are intermittently conveyed to the conveying mechanism 2. The conveying mechanism 2 conveys the gypsum board from back to front, and the left and right positions of the gypsum board can be adjusted during the conveying process. The device can unify the detection positions of multiple gypsum boards, thereby reducing the detection error. After the gypsum board position is transported, the lifting mechanism 3 supports the gypsum board to move upward. At this time, the conveying mechanism 2 can transport the next gypsum board sample. After the lifting mechanism 3 lifts the gypsum board to the specified position, the pressure mechanism 4 can apply a gradually increasing load to the gypsum board until the gypsum board sample breaks, and the maximum load that the gypsum board sample can withstand is tested. The broken gypsum board will fall into the cleaning mechanism 5, and then the cleaning mechanism 5 will process the broken gypsum board to prevent the fragments from falling on the next gypsum board to be tested, which will affect the detection result.

[0026] See also Figure 1 and Figure 2, the conveying mechanism 2 includes a supporting component 21, a feeding component 22 and a rectifying component 23. The supporting component 21 includes two left and right side plates 211. The two side plates 211 are respectively fixedly connected to the front and rear inner walls of the two U-shaped frames 1. The bottom between the two side plates 211 is fixedly connected with a bottom plate 212 in common. The upper surface of the bottom plate 212 is fixedly connected with two front and rear parallel slide rails 213. The feeding component 22 and the rectifying component 23 are both arranged on the supporting component 21. While the feeding component 22 conveys the gypsum board forward, the rectifying component 23 adjusts and limits it. The feeding component 22 includes a plurality of fourth rotating shafts 221 arranged at equal intervals in the front and rear. The surfaces of the plurality of fourth rotating shafts 221 are fixedly connected with transmission rollers 222. The left and right ends of the plurality of fourth rotating shafts 221 respectively rotate through the left and right two side plates 211 and are fixedly connected with fourth gears 224. The left and right ends of one of the fourth rotating shafts 221 penetrate through the corresponding fourth gears 224 and are fixedly connected with a worm 223. A plurality of fifth gears 225 arranged at equal intervals are rotatably arranged on the surfaces of the two side plates 211. The plurality of fifth gears 225 and the plurality of fourth gears 224 are arranged in an alternating manner, and the plurality of fifth gears 225 are all meshed with the adjacent fourth gears 224. A first motor 226 is fixedly installed on the inner side of one of the U-shaped frames 1 through a mounting seat. The output shaft of the first motor 226 is fixedly connected with the worm 223 on the same side. After the first motor 226 drives one of the fourth rotating shafts 221 to rotate, the corresponding two fourth gears 224 will rotate synchronously. Then, through the meshing between the plurality of fourth gears 224 and the fifth gears 225, the plurality of transmission rollers 222 can be rotated simultaneously. Moreover, the alternating arrangement of the plurality of fourth gears 224 and the plurality of fifth gears 225 can achieve the purpose of rotating the plurality of transmission rollers 222 in the same direction, so as to convey the gypsum board by the plurality of transmission rollers 222.

[0027] Refer to Figure 2, the rectifying component 23 includes two cross bars 231 on the left and right. The bottoms of the two cross bars 231 are both slidably arranged on the surfaces of the two slide rails 213 through sliders. The upper surfaces of the cross bars 231 are rotatably connected with a plurality of equally spaced rotating columns 232 through round shafts. The plurality of rotating columns 232 and the plurality of driving rollers 222 are arranged alternately, and the tops of the rotating columns 232 are higher than the driving rollers 222. The center position of the upper surface of the bottom plate 212 is rotatably connected with two overlapping sixth gears 234 up and down through a first connecting shaft. The front and rear sides of the upper sixth gear 234 are both engaged with a first rack 233. The two first racks 233 are respectively fixedly connected with the left and right cross bars 231. An electric push rod 235 is fixedly installed on the upper surface of the bottom plate 212. The telescopic end of the electric push rod 235 is fixedly connected with a second rack 236. The tooth surface of the second rack 236 is engaged with the lower sixth gear 234. By pulling the second rack 236 with the electric push rod 235, the two sixth gears 234 are rotated simultaneously. Then, the upper sixth gear 234 can drive the front and rear first racks 233 to move, so that the left and right cross bars 231 follow the corresponding first racks 233 to approach each other, driving the plurality of rotating columns 232 on the left and right sides to approach each other. The left and right groups of rotating columns 232 play a role in rectifying the gypsum board during the conveying process to ensure the unity of the position of the gypsum board during detection.

[0028] Refer to Figure 1 and Figure 3 , the lifting mechanism 3 includes two first rotating shafts 31 up and down. The front and rear ends of the two first rotating shafts 31 both rotatably penetrate the side walls of the U-shaped frame 1 and are fixedly connected with sprockets 33. A chain 34 is commonly engaged between the upper and lower sprockets 33 on the same side. The surface of the chain 34 is fixedly connected with a plurality of equally spaced lifting plates 35. A worm gear 32 is fixedly connected to the surface of the lower first rotating shaft 31. The worm gears 223 on the left and right sides of the outer surface of the fourth rotating shaft 221 are respectively engaged with the corresponding two worm gears 32, and the two worm gears 223 have opposite helix directions. The first motor 226 drives the fourth rotating shaft 221 to rotate. While achieving the purpose of conveying the gypsum board, it can drive the corresponding worm gears 32 and the first rotating shafts 31 to rotate through the two worm gears 223, and the two first rotating shafts 31 rotate in opposite directions. After one of the first rotating shafts 31 in the same U-shaped frame 1 rotates, through the transmission of the sprocket 33 and the chain 34, the chain 34 can be operated, and the left and right chains 34 rotate in opposite directions, so as to achieve the purpose of the common upward operation of the mutually approaching sides of the two chains 34. The distance between the left and right groups of lifting plates 35 is smaller than the distance between the left and right U-shaped frames 1. The plurality of lifting plates 35 are all set in an L shape. When the lifting plates 35 follow the chain 34 to operate to the vertical section, the gypsum board on the conveying mechanism 2 can be lifted by the left and right groups of lifting plates 35 until it is lifted to the specified position, and then the strength detection is carried out by the pressing mechanism 4.

[0029] Refer to Figure 1 , the pressing mechanism 4 includes a connecting plate 41. The left and right ends of the connecting plate 41 are respectively fixedly connected to the tops of two U-shaped frames 1. A cylinder 42 is fixedly arranged through the middle position of the connecting plate 41. The telescopic end of the cylinder 42 is arranged downward, and the telescopic end of the cylinder 42 is fixedly connected to a pressing hammer 43. When the gypsum board is lifted to a certain height by the lifting mechanism 3, the cylinder 42 can push the pressing hammer 43 to apply a downward pressure on the gypsum board through the pressing hammer 43, and the lifting mechanism 3 provides an upward thrust to the gypsum board, so that the load borne by the gypsum board gradually increases until the gypsum board breaks, thereby detecting the maximum load that the gypsum board can bear.

[0030] Refer to Figure 4 and Figure 5 , the cleaning mechanism 5 includes a support assembly 51, a transmission assembly 52 and a pumping and moving assembly 53. The support assembly 51 includes four vertical plates 511 distributed in a matrix. The four vertical plates 511 are respectively located on the front and rear sides of the conveying mechanism 2. A baffle 512 is fixedly connected between the two vertical plates 511 on the front side of the conveying mechanism 2, and the baffle 512 is located in front of the driving roller 222. When the plurality of driving rollers 222 continuously convey the gypsum board, the gypsum board will abut against the baffle 512, so as to stop moving forward. At this time, the left and right positions of the gypsum board have been adjusted and limited by the regularizing assembly 23. After that, the positions of the plurality of gypsum boards supported by the lifting plate 35 can be kept consistent, ensuring that the detection positions of the gypsum boards are consistent, thereby reducing the detection error.

[0031] Refer to Figure 4 and Figure 5The withdrawing assembly 53 includes two third rotating shafts 531 at the front and rear, and the left and right ends of the two third rotating shafts 531 are respectively rotatably connected to the two vertical plates 511 on the same side. The transmission assembly 52 includes two second rotating shafts 521 at the front and rear, and the two second rotating shafts 521 are respectively rotatably arranged on the opposite surfaces of the corresponding two vertical plates 511, and the surfaces of the two second rotating shafts 521 are jointly connected with the third synchronous belt 526 through the first synchronous wheel. The surface of the front second rotating shaft 521 is fixedly connected with the first gear 522, and the second gear 523 is meshed above the first gear 522. The second gear 523 is rotatably arranged on the side of the vertical plate 511 through the second connecting shaft, and the second connecting shaft rotates through the corresponding vertical plate 511, and is jointly connected with the first synchronous belt 524 through the second synchronous wheel with the third rotating shaft 531 on the same side. The second rotating shaft 521 located at the rear side rotates through the corresponding vertical plate 511 and is The third rotating shaft 531 on one side is connected to the second synchronous belt 525 through the third synchronous wheel. A second motor 527 is arranged on the surface of one of the vertical plates 511 on the front side. The output shaft of the second motor 527 rotates and passes through the corresponding vertical plate 511 and is fixedly connected to the second rotating shaft 521. The second motor 527 is a forward and reverse motor. When the second motor 527 drives the second rotating shaft 521 on the front side to rotate forward, the third rotating shaft 531 on the rear side will rotate forward at the same time through the transmission action of the third synchronous belt 526 and the second synchronous belt 525. At this time, the first gear 522 drives the second gear 523 and the second connecting shaft to reverse, so that the third rotating shaft 531 on the front side is reversed through the first synchronous belt 524, so as to achieve the purpose of the two third rotating shafts 531 turning in opposite directions. The same motor drives the two third rotating shafts 531, which can ensure the synchronous rotation of the two third rotating shafts 531.

[0032] See also Figure 4 and Figure 5, third gears 532 are fixedly connected to the left and right sides of the outer surfaces of the two third rotating shafts 531. Support blocks 533 are fixedly connected to the surfaces of the four vertical plates 511 through connecting blocks. The four support blocks 533 are respectively located below the four corresponding third gears 532. Two left and right rectangular frames 534 are sleeved on the outer parts of the two third rotating shafts 531. The inner walls of the horizontal sections on the upper sides of the multiple rectangular frames 534 are all provided with tooth rows. The third gears 532 mesh with the tooth rows of the horizontal sections on the upper sides of the rectangular frames 534. The horizontal sections on the lower sides of the rectangular frames 534 are slidably connected to the front and back of the support blocks 533. The upper surfaces of the two rectangular frames 534 on the same side are jointly provided with a material receiving hopper 535. The material receiving hopper 535 is composed of a rectangular plate and a U-shaped frame integrally connected to the upper surface of the rectangular plate, and the U-shaped frame is located at the corner of the upper surface of the rectangular plate. The two material receiving hoppers 535 are symmetrically arranged front and back. The openings of the U-shaped frames of the two material receiving hoppers 535 are both arranged on the side of the rectangular plate away from the pressing mechanism 4. The bottom of the opening of the material receiving hopper 535 is hinged to the upper surfaces of the two rectangular frames 534 through hinge seats. When the third rotating shaft 531 rotates, it can drive the rectangular frame 534 to move back and forth through the third gear 532. When the second motor 527 rotates forward, the front and rear groups of rectangular frames 534 can be driven to approach each other through the two third rotating shafts 531 respectively. By the forward and reverse rotation of the second motor 527, the front and rear two material receiving hoppers 535 can be driven to approach or move away from each other. When the two material receiving hoppers 535 are in contact with each other, they are located above the conveying mechanism 2 and are used to承接 the broken gypsum board. And through the action of the U-shaped frame, the broken gypsum board fragments can be separated on the two material receiving hoppers 535. Then the second motor 527 rotates in reverse, driving the front and rear groups of rectangular frames 534 and the two material receiving hoppers 535 to move away from each other until the rectangular frame 534 moves out from above the conveying mechanism 2, ensuring that the rectangular frame 534 does not hinder the lifting plate 35 from driving the gypsum board to move upward. At this time, the mutually approaching ends of the two material receiving hoppers 535 are still located above the conveying mechanism 2. When the lifting plate 35 supports the next gypsum board to move upward, the mutually approaching ends of the two material receiving hoppers 535 can be lifted upward respectively by the front and rear ends of the gypsum board, so that the material receiving hopper 535 is turned over and tilted, and the broken gypsum board fragments in the material receiving hopper 535 can be poured out. The gypsum board to be detected continues to move upward, so that it is separated from the contact with the material receiving hopper 535, and the material receiving hopper 535 turns back to its original position again. And through the forward rotation of the second motor 527, the two material receiving hoppers 535 are made to contact each other again, and the broken gypsum board after detection can be承接 again.

[0033] During operation, multiple gypsum board samples are intermittently conveyed to multiple transmission rollers 222 through external conveying equipment, and then the first motor 226 drives the multiple transmission rollers 222 to rotate, so that the gypsum board continues to move forward. During the movement, the electric push rod 235 drives the left and right cross bars 231 to move closer or farther from each other, thereby driving the corresponding rotating column 232 to move. The left and right positions of the gypsum board are adjusted and limited by the rotating column 232 without affecting the forward and backward movement of the gypsum board. After the gypsum board is against the baffle 512, its position is adjusted. The whole is completed, and at the same time, the fourth rotating shaft 221 will drive the corresponding worm wheel 32 and the first rotating shaft 31 to rotate in opposite directions through two worms 223 with opposite rotation directions, so that the left and right chains 34 rotate in opposite directions, and the lifting plate 35 will rotate synchronously with the corresponding chain 34. When the lifting plate 35 rises from the lower direction of the conveying mechanism 2, the gypsum board adjusted on the conveying mechanism 2 can be lifted. At this time, the two receiving hoppers 535 are driven away from each other by the second motor 527 until the front and rear rectangular frames 534 move out of the conveyor. The two receiving hoppers 535 are above the conveying mechanism 2, and the ends of the two receiving hoppers 535 that are close to each other are still above the conveying mechanism 2. When the lifting plate 35 drives the gypsum board to move up, the two receiving hoppers 535 will be pushed by the front and rear ends of the gypsum board respectively, so that the receiving hoppers 535 will be turned over. After that, the gypsum board continues to move up. After the gypsum board is out of contact with the bottom of the receiving hopper 535, the receiving hopper 535 will be turned back to the horizontal position. At this time, the second motor 527 is reversed to move the two receiving hoppers 535 back to the position where they conflict with each other, and the gypsum board is raised to a suitable position. Afterwards, the cylinder 42 pushes the pressure hammer 43, which breaks the gypsum board, thereby testing the strength of the gypsum board. The broken gypsum boards will fall into the two receiving hoppers 535 respectively. At this time, the second motor 527 rotates forward again, driving the two receiving hoppers 535 away from each other again, and the next gypsum board to be tested supported by the lifting plate 35 pushes the two receiving hoppers 535 again, thereby pouring out the broken gypsum board in the receiving hopper 535, preventing gypsum board fragments from falling on the gypsum board to be tested, causing problems affecting subsequent test results.
