Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board conveying, and particularly relates to an open roller way conveying device for a light-weight and high-strength gypsum board line. Background Art

[0002] During the production process of gypsum boards, the gypsum boards are conveyed through an open roller way. The traditional open roller way uses a stainless steel roller way, and the transmission method is to drive the rotation and transportation of the stainless steel roller way through an entire roller chain. The smoothness of the roller surface of the stainless steel roller way is insufficient. After a period of use, it is deformed, the roller way has a large jump, and the high-speed transmission of the roller chain generates a large noise. The wet board vibrates greatly during the operation and transportation process, and the facing paper on the board surface is easily adhered to the roller surface, causing damage to the board and seriously affecting the quality of the board.

[0003] The prior art usually uses alumina rollers instead of stainless steel roller ways. The radial jump of the roller surface of the traditional stainless steel roller way is about 0.3 mm. Compared with the radial jump of the roller surface of the stainless steel roller way, the radial jump of the roller surface of the alumina roller way reaches 0.02 mm, and the roller surface reaches a mirror effect. The wet board has a small jump during the transportation process, and the facing paper of the board is not easily adhered, reducing the damage to the board.

[0004] The alumina roller way in the prior art reduces the jump of the roller surface of the board to a certain extent. However, the roller surface of the alumina roller way will also be uneven after long-term use. If it cannot be processed in time, it will cause continuous jumping of the subsequent board, resulting in damage to the board. To replace the corresponding alumina roller, the entire roller way needs to be braked, affecting the transportation rate of the board. Summary of the Invention

[0005] Therefore, the present invention provides an open roller way conveying device for a light-weight and high-strength gypsum board line, effectively solving the problems in the prior art that if the alumina roller is not processed in time, it will cause continuous jumping of the subsequent board, resulting in damage to the board, and replacing the alumina roller affects the production and transportation of the board.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] As Figure 1 shown, the present invention provides a light - weight and high - strength gypsum board line open roller path conveying device, which includes a driving and conveying roller path group 1, a transmission driving mechanism 2, a disassembly, installation and replacement single roller 3, a roller path lifting driving mechanism 4 and an installation driving mechanism 5.

[0050] Among them, the driving and conveying roller path group 1 is used to provide a plurality of conveying single rollers 11 to drive the gypsum board to be transported forward.

[0051] The transmission driving mechanism 2 is arranged on the driving and conveying roller path group 1. The transmission driving mechanism 2 is used to drive the driving and conveying roller path group 1 to rotate so as to drive the gypsum board to be transported forward.

[0052] The disassembly and replacement single roller 3 is arranged in the driving and conveying roller path group 1. The disassembly and replacement single roller 3 is used to replace the conveying single roller 11 at the corresponding position where the gypsum board has a springboard. The disassembly and replacement single roller 3 can be lifted and lowered to be adjusted to be flush with the conveying single roller 11. Both the conveying single roller 11 and the disassembly and replacement single roller 3 can be detachably installed.

[0053] The roller path lifting drive mechanism 4 is arranged on the sides of the conveying single roller 11 and the disassembly and replacement single roller 3. The roller path lifting drive mechanism 4 is used to drive the conveying single roller 11 to descend and drive the disassembly and replacement single roller 3 to ascend when the conveying single roller 11 and the disassembly and replacement single roller 3 change positions.

[0054] The installation drive mechanism 5 is arranged at the end where the conveying single roller 11 and the disassembly and replacement single roller 3 are connected to the transmission drive mechanism 2. The installation drive mechanism 5 is used to drive and connect with the transmission drive mechanism 2 to establish the connection relationship between the conveying single roller 11, the disassembly and replacement single roller 3 and the transmission drive mechanism 2, so that the transmission drive mechanism 2 drives and drives the conveying single roller 11 and the disassembly and replacement single roller 3 to rotate.

[0055] In the present invention, a disassembly and replacement single roller 3 for replacement is arranged at each conveying single roller 11. When the conveying single roller 11 and the disassembly and replacement single roller 3 change positions, the roller path lifting drive mechanism 4 drives the conveying single roller 11 to descend and the disassembly and replacement single roller 3 to be lifted and lowered. And the installation drive mechanism 5 drives to establish the connection relationship between the conveying single roller 11, the disassembly and replacement single roller 3 and the transmission drive mechanism 2, so that the transmission drive mechanism 2 can drive the corresponding conveying single roller 11 or the disassembly and replacement single roller 3 to rotate. When the jumping amplitude of the gypsum board exceeds a certain range, it drives the conveying single roller 11 to be replaced, and the driving and conveying roller path group 1 is updated in time without affecting the transportation of the gypsum board.

[0056] The present invention conveys the gypsum board through the driving and conveying roller path group 1. The driving and conveying roller path group 1 adopts the following preferred embodiments, such as Figure 2 As shown, the driving and conveying roller path group 1 includes a first driving shaft 12 arranged on the conveying single roller 11 and a first mounting shaft seat 13 arranged on the side of the driving shaft 12; the first driving shaft 12 is rotatably arranged in the first mounting shaft seat 13.

[0057] The first mounting shaft seat 13 serves as the bearing seat of the first driving shaft 12, and the first driving shaft 12 can rotate on the first mounting shaft seat 13.

[0058] In the present invention, the disassembly and replacement single roller 3 can replace the conveying single roller 11. Therefore, the structures, shapes and sizes of the conveying single roller 11 and the disassembly and replacement single roller 3 are the same. The structure of the disassembly and replacement single roller 3 is as follows, such as Figure 3As shown in the figure, a second drive shaft 31 is provided on the side of the dismountable and replaceable single roller 3. A second mounting shaft seat 32 is provided on the side of the second drive shaft 31. The second drive shaft 31 is rotatably arranged on the second mounting shaft seat 32. The second mounting shaft seat 32 serves as the bearing seat of the second drive shaft 31, and the second drive shaft 31 can rotate on the second mounting shaft seat 32.

[0059] In the present invention, both the conveying single roller 11 and the dismountable and replaceable single roller 3 are detachable. It is necessary to arrange rotatable intermediates in the first mounting shaft seat 13 and the second mounting shaft seat 32. Therefore, rotary shaft cylinders 33 are arranged in both the first mounting shaft seat 13 and the second mounting shaft seat 32. The ends of the first drive shaft 12 and the second drive shaft 31 are both arranged in the rotary shaft cylinders 33.

[0060] In the above embodiment, the rotary shaft cylinder 33 can rotate in the first mounting shaft seat 13 and the second mounting shaft seat 32, thereby driving the first drive shaft 12 and the second drive shaft 31 to rotate, and the first drive shaft 12 and the second mounting shaft 31 can be removed from the rotary shaft cylinder 33.

[0061] In order to enable the rotary shaft cylinder 33 to rotate and be positioned in the first mounting shaft seat 13 and the second mounting shaft seat 32, the present invention also makes the following design, as Figure 2 and Figure 3 shown in the figure, a limiting ring 38 is provided on the side of the rotary shaft cylinder 33. Ring grooves 34 are provided in the first mounting shaft seat 13 and the second mounting shaft seat 32. The limiting ring 38 is movably installed in the ring grooves 34, and the rotary shaft cylinder 33 rotates in the first mounting shaft seat 13 and the second mounting shaft seat 32.

[0062] In the above embodiment, the limiting ring 38 is restricted by the ring grooves 34, so that the rotary shaft cylinder 33 can only rotate in the first mounting shaft seat 13 and the second mounting shaft seat 32, but cannot change its position.

[0063] In addition, since both the conveying single roller 11 and the dismountable and replaceable single roller 3 are detachable, in order to enable the first drive shaft 12 and the second mounting shaft 31 to be installed and removed from the rotary shaft cylinder 33, the present invention also makes the following design. Clamping blocks 35 are provided on both the first drive shaft 12 and the second drive shaft 31; a clamping groove plate 36 is arranged in the rotary shaft cylinder 33, a telescopic shaft rod 37 is arranged in the rotary shaft cylinder 33, the end of the telescopic shaft rod 37 is connected to the clamping groove plate 36, and the clamping blocks 35 are clamped with the clamping groove plate 36.

[0064] When the first drive shaft 12 and the second drive shaft 31 are not installed, under the action of the telescopic shaft rod 37, the clamping groove plate 36 extends a certain distance outside the rotating shaft cylinder 33. When it is necessary to install the first drive shaft 12 and the second drive shaft 31, the clamping blocks 35 at one end of the first drive shaft 12 and the second drive shaft 31 are clamped on the clamping groove plate 36, and the clamping groove plate 36 is pushed inward until the clamping blocks 35 at the other end of the first drive shaft 12 and the second drive shaft 31 approach and are clamped on the corresponding clamping groove plates 36. At this time, both ends of the first drive shaft 12 and the second drive shaft 31 are clamped and installed.

[0065] In the present invention, the transmission drive mechanism 2 drives the first drive shaft 12 and the second drive shaft 31 to rotate. The transmission drive mechanism 2 of the present invention adopts the following preferred embodiments, as Figure 4 shown, the transmission drive mechanism 2 includes a first transmission sprocket 21 arranged on the side of the first drive shaft 12, a second transmission sprocket 22 arranged on the side of the second drive shaft 31, and a toothed chain 23 arranged on the first transmission sprocket 21 and the second transmission sprocket 22.

[0066] In the above embodiment, in order to support the toothed chain 23, support sprockets 24 are arranged inside the first drive toothed chain 23. There are two support sprockets 24, which are respectively arranged on both sides of the first transmission sprocket 21 and the second transmission sprocket 22. The support sprockets 24 not only play a role in supporting the toothed chain 23, but also make the transmission of the support sprockets 24 drive the toothed chain 23 to run, thereby driving the first transmission sprocket 21 and the second transmission sprocket 22 to rotate. This indirect transmission method can reduce the impact on the gypsum board caused by the support sprockets 24 directly transmitting and skipping teeth. When the support sprockets 24 are not properly meshed with the toothed chain 23, resulting in tooth skipping, the transportation or transmission instability cannot continue, which will cause the transportation of the gypsum board to stop or be unstable. In this case, if the support sprockets 24 directly drive the first drive shaft 12 and the second drive shaft 31, the entire support sprockets 24 and the toothed chain 23 need to be checked and replaced, resulting in the gypsum board being unable to be transported for a short time. However, if tooth skipping occurs at the support sprockets 24, the corresponding first transmission sprocket 21 and the second transmission sprocket 22 can also directly drive the gypsum board to continue running, and reduce the contact area between the first transmission sprocket 21 and the second transmission sprocket 22 and the toothed chain 23. When the toothed chain 23 is not accurately meshed at the support sprockets 24, it will only cause wear to the support sprockets 24 and may not affect the rotation of the first transmission sprocket 21 and the second transmission sprocket 23. Therefore, it can also reduce the impact of the toothed chain 23 jamming and jumping on the first drive shaft 12 and the second drive shaft 31.

[0067] For the installation of the first driving sprocket 21, the second driving sprocket 22 and the supporting sprocket 24, the present invention also makes the following design. An installation frame 25 is arranged on the side of the driving conveyor roller path group 1. The first driving sprocket 21, the second driving sprocket 22 and the supporting sprocket 24 are all rotatably arranged on the installation frame 25. The first driving sprocket 21, the second driving sprocket 22 and the supporting sprocket 24 form a driving group, and the mutually adjacent supporting sprockets 24 in adjacent driving groups are coaxially connected.

[0068] In the above embodiment, the coaxial connection of the mutually adjacent supporting sprockets 24 in adjacent driving groups is also for the driving connection of adjacent driving groups, so that the entire driving conveyor roller path group 1 can be driven by one driving source to operate the entire roller path group.

[0069] In addition, in order to ensure the tension of the toothed chain 23, the present invention also makes the following design. A tensioning wheel 26 is arranged inside the toothed chain 23. An installation cylinder seat 27 is arranged on the installation frame 25. A rotating shaft frame 28 is arranged inside the installation cylinder seat 27. The tensioning wheel 26 is rotatably installed at the end of the rotating shaft frame 28. A first torsion spring is arranged inside the installation cylinder seat 27, and the end of the first torsion spring is connected to the rotating shaft frame 28.

[0070] In the above embodiment, under the action of the first torsion spring, the rotating shaft frame 28 drives the tensioning wheel 26 to press down the toothed chain 23, tensioning the toothed chain 23 downward in real time, ensuring good tension of the toothed chain 23, improving the transmission efficiency, reducing the situation that the toothed chain 23 does not mesh well with the corresponding sprocket, and subsequent adjustment of the roller position and the length of the toothed chain 23 to adjust the tension of the toothed chain 23 does not require separate manual adjustment.

[0071] In addition, when the conveying single roller 11 and the disassembly and replacement single roller 3 are replaced in position, the present invention drives the conveying single roller 11 to descend and drives the disassembly and replacement single roller 3 to ascend through the roller lifting drive mechanism 4. The roller lifting drive mechanism 4 of the present invention adopts the following preferred embodiment, as Figure 5 shown, the roller lifting drive mechanism 4 includes a lifting connection seat 41 arranged on the first installation shaft seat 13 and the second installation shaft seat 32, a connecting threaded rod 42 arranged on the lifting connection seat 41, and a first driving motor 43 arranged at the end of the connecting threaded rod 42; the connecting threaded rod 42 is connected to the output end of the first driving motor 43. A threaded groove for the threaded connection of the connecting threaded rod 42 is arranged on the lifting connection seat 41, and a limit bolt 44 is arranged at the end of the connecting threaded rod 42.

[0072] In the above embodiment, the first driving motor 43 drives the connecting threaded rod 42 to rotate. Under the rotation of the connecting threaded rod 42, the lifting connection seat 41 gradually rises or gradually descends, and the limit bolt 44 limits the rising height of the lifting connection seat 41.

[0073] In the present invention, after the corresponding conveying single roller 11 and the disassembly, installation and replacement single roller 3 are replaced in position, the connection relationship between the corresponding conveying single roller 11, the disassembly, installation and replacement single roller 3 and the transmission driving mechanism 2 needs to be established. The present invention connects the installation driving mechanism 5 with the transmission driving mechanism 2 to establish the connection relationship between the conveying single roller 11, the disassembly, installation and replacement single roller 3 and the transmission driving mechanism 2, so that the transmission driving mechanism 2 drives the conveying single roller 11 and the disassembly, installation and replacement single roller 3 to rotate. The installation driving mechanism 5 of the present invention adopts the following preferred embodiments, such as Figure 2 and Figure 3 As shown, the installation driving mechanism 5 includes an installation cylinder base 51 connected to the end of the rotating shaft cylinder 33, a driving cylinder 52 arranged in the installation cylinder base 51, and a telescopic linkage rod 53 connected to the output end of the driving cylinder 52; connecting shafts 54 are arranged on both the first transmission sprocket 21 and the second transmission sprocket 22, a connecting cavity 55 is arranged inside the connecting shaft 54, and the end of the telescopic linkage rod 53 extends into the connecting cavity 55.

[0074] In the above embodiment, the connecting shaft 54 cannot directly drive the telescopic linkage rod 53 to rotate. In order to enable the connecting shaft 54 to directly drive the telescopic linkage rod 53 to rotate, the present invention also makes the following design, such as Figure 5 and Figure 6 As shown, a plurality of connecting grooves 56 are arranged on the circumferential side of the end of the telescopic linkage rod 53, a connecting block 57 is arranged in the connecting groove 56, the connecting block 57 is connected in the connecting groove 56 through a linkage shaft 58, a second torsion spring is arranged on the linkage shaft 58, and the end of the torsion spring is connected to the linkage shaft 58; a linkage groove 59 is arranged in the connecting cavity 55, and the connecting block 57 cooperates with the linkage groove 59; the inner diameters of the installation cylinder base 51 and the connecting cavity 55 are the same.

[0075] The driving cylinder 52 drives the telescopic linkage rod 53 to enter the connecting cavity 55, and the connecting block 57 follows to enter the connecting cavity 55. In the initial state, the connecting block 57 may not directly cooperate with the linkage groove 59, but the rotation of the first transmission sprocket 21 and the second transmission sprocket 22 drives the corresponding connecting shaft 54 to rotate, thereby driving the linkage groove 59 to rotate to correspond to the connecting block 57. At the moment when the linkage groove 59 rotates to correspond to the connecting block 57, under the action of the torsion spring, the connecting block 57 rotates into the linkage groove 59 under the elastic force. At this time, the rotation of the connecting shaft 54 can drive the corresponding telescopic linkage shaft 53 to rotate, thereby driving the installation cylinder base to rotate, and then driving the first driving shaft 12 and the second driving shaft 31 to rotate through the rotation adjustment 33.

[0076] In order to enable the first drive sprocket 21 and the second drive sprocket 22 to rotate and drive the corresponding connecting shaft 54 to rotate, which can drive the linkage groove 59 to rotate to correspond to the connecting block 57 in the initial situation, it is necessary to ensure that the rotating shaft cylinder 33 and the mounting cylinder base 51 do not move during the rotation of the first drive sprocket 21 and the second drive sprocket 22. The present invention makes the following design: the frictional force between the connecting block 57 and the inner wall of the connecting cavity 55 is less than the frictional force between the rotating shaft cylinder 33 and the inner walls of the first mounting shaft seat 13 and the second mounting shaft seat 32.

[0077] In the above embodiment, due to the relatively small frictional force between the connecting block 57 and the inner wall of the connecting cavity 55, it is impossible to drive the rotating shaft cylinder 33 and the mounting cylinder base 33 to frictionally rotate on the inner walls of the first mounting shaft seat 13 and the second mounting shaft seat 32 through the frictional force between the connecting block 57 and the connecting cavity 55.

[0078] In summary, the main implementation process of the present invention is as follows:

[0079] The transmission and conveying roller path group 1 transports the gypsum board: the support sprocket 24 is driven to rotate, driving the toothed chain 23 to rotate, thereby driving the first drive sprocket 21 and the second drive sprocket 22 to rotate. Through the connecting shaft 55, the rotating shaft cylinder 33 and the mounting cylinder base 51 are driven to rotate, and thus the conveying single roller 11 is driven to rotate through the first drive shaft 12, driving the gypsum board to be transported forward;

[0080] Replace the roller path: When the jumping amplitude of the gypsum board exceeds a certain range, the corresponding conveying single roller 11 at the corresponding position is replaced. The driving cylinder 52 drives the telescopic linkage rod 53 corresponding to the conveying single roller 11 to disengage from the connecting cavity 55. The first driving motor 43 drives the connecting threaded rod 42 to rotate. Under the rotation of the connecting threaded rod 42, the lifting connecting seat 41 gradually descends, driving the conveying single roller 11 to lower its position, and driving the disassembly and replacement single roller 3 to rise to be flush with the other conveying single rollers 11;

[0081] Establish a connection between the transmission drive mechanism 2 and the disassembly and replacement single roller 3: The driving cylinder 52 drives the telescopic linkage rod 53 of the disassembly and replacement single roller 3 to enter the connecting cavity 55. The connecting block 57 follows and enters the connecting cavity 55. The first drive sprocket 21 and the second drive sprocket 22 rotate to drive the corresponding connecting shaft 54 to rotate, thereby driving the linkage groove 59 to rotate to correspond to the connecting block 57. Under the action of the torsion spring, the connecting block 57 rotates under the elastic force to the inside of the linkage groove 59. At this time, the rotation of the connecting shaft 54 can drive the corresponding telescopic linkage shaft 53 to rotate, thereby driving the mounting cylinder base to rotate, and thus driving the second drive shaft 31 to rotate through the rotation adjustment 33;
