Description

Technical Field

[0001] This invention relates to the field of waste removal technology in gypsum board production lines, specifically to a single-board flipping waste discharge system for gypsum board production lines. Background Technology

[0002] The gypsum board production process includes forming, drying, slitting, edge banding, and stacking. After drying, the gypsum board enters the slitting process, where multiple gypsum boards are stacked in multiple layers for slitting. This allows multiple boards to be edge-banded into a storage unit for stacking. However, in actual production, if a single-layer board is encountered during the slitting and edge banding process and proceeds directly to the next stage for edge banding, it directly affects the quantity of boards in the entire stack. When multiple sets of single boards enter the stacking table, manual verification of the total number of boards on the stack is required, consuming a significant amount of manpower.

[0003] Therefore, existing technologies often involve waste removal of veneer gypsum boards between slitting processes to ensure automated operation of subsequent slitting, edge banding, and stacking. Most existing waste removal methods are: installing waste removal cylinders on the side of the conveyor rollers to remove waste from the veneer gypsum boards during transmission, or installing lifting double-layer roller conveyors between the conveyor rollers, with the upper roller conveyor lifting the veneer gypsum boards to remove waste and the lower roller conveyor conveying multiple layers of stacked gypsum boards. The second waste removal method is more suitable for online production.

[0004] The second waste removal method also has the following drawbacks:

[0005] (1) Most of the lifting double-layer roller conveyors use two power components, namely one power component for the upper roller conveyor and one power component for the lower roller conveyor. On the one hand, this results in high noise, low energy utilization, and complex control logic. On the other hand, the installation position of the power component of the upper roller conveyor will affect the normal conveying of gypsum board by the lower roller conveyor.

[0006] (2) Most waste removal methods involve setting up a side-push cylinder on the side of the roller conveyor to push the gypsum board to the waste discharge platform. The waste discharge efficiency is slow and the board is prone to breakage. Summary of the Invention

[0007] The purpose of this invention is to provide a single-board flipping waste discharge system for gypsum board production lines, in order to solve the technical problems of existing lifting double-layer roller conveyors that mostly use two power components and side-push cylinders to push gypsum boards to the waste discharge platform, resulting in slow waste discharge efficiency and easy board breakage.

[0008] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0009] A single-board flipping waste discharge system for a gypsum board production line includes,

[0010] The first conveying and detection system is used to convey gypsum board and simultaneously detect the thickness of the gypsum board in real time using multiple detection modules arranged above the gypsum board and distributed along the width direction of the gypsum board.

[0011] The second conveying and waste discharge system is used to continue conveying the gypsum board, and during the conveying process, the thickness of a single gypsum board is used to lift and discharge the waste.

[0012] The waste stacking platform is located on the side of the second waste conveying system and is used to receive and convey the waste gypsum board.

[0013] The second waste conveying system includes a conveying roller conveyor and a lifting double-layer roller conveyor disposed between the conveying roller conveyors. The upper roller conveyor of the lifting double-layer roller conveyor is used to lift the gypsum board that needs to be disposed of, and the lower roller conveyor of the lifting double-layer roller conveyor is used to continue conveying the gypsum board that does not need to be disposed of.

[0014] The upper and lower roller conveyors of the lifting double-layer roller conveyor share the same power drive component. The power drive component drives the lifting double-layer roller conveyor to rotate synchronously. A stripping cylinder is installed below the upper roller conveyor to push it to tilt. The stripping cylinder moves up and down synchronously with the lifting double-layer roller conveyor. When the lifting double-layer roller conveyor is raised to its maximum height, the stripping cylinder pushes the upper roller conveyor to tilt independently, so that the gypsum board raised by the upper roller conveyor is transferred to the waste stacking platform.

[0015] In a preferred embodiment of the present invention, the power drive assembly is mounted on the lower roller conveyor, and the power drive assembly directly drives the lower roller conveyor to rotate in the same direction as the conveying roller conveyor.

[0016] The upper and lower roller conveyors are connected by a synchronous transmission assembly. The upper roller conveyor rotates synchronously and in the same direction with the lower roller conveyor using the synchronous transmission assembly. The upper and lower roller conveyors of the lifting double-layer roller conveyor can be driven separately by the synchronous transmission assembly. The lower roller conveyor remains stationary by separating from the upper roller conveyor during waste discharge.

[0017] As a preferred embodiment of the present invention, the lower roller conveyor includes two open track plates at the front and rear, and a plurality of first cylindrical rollers uniformly arranged inside the two open track plates. The same end of all the first cylindrical rollers is mounted inside the open track plate by bearings, and the other end of all the first cylindrical rollers is connected by a first transmission chain arranged between two adjacent first cylindrical rollers.

[0018] The power drive assembly includes a drive motor disposed below the open track plate and a drive chain disposed on the output wheel of the drive motor. A synchronous rotating wheel is disposed on the first cylindrical roller located away from the waste stacking platform and on the outermost side. The drive chain is disposed between the synchronous rotating wheel and the output wheel of the drive motor. The power drive assembly drives the first cylindrical roller located on the outermost side to rotate through the drive chain, and all the first cylindrical rollers rotate synchronously through multiple first transmission chains.

[0019] As a preferred embodiment of the present invention, the upper roller conveyor includes a track panel close to the waste stacking platform, a hollow track plate away from the waste stacking platform, and a plurality of second cylindrical rollers uniformly arranged between the track panel and the hollow track plate. One end of all the second cylindrical rollers is mounted on the track panel through a bearing seat, and the other end of all the second cylindrical rollers is mounted on the side panel of the hollow track plate through a bearing ring.

[0020] All the ends of the second cylindrical rollers inside the hollow track plate are connected by a second drive chain disposed between two adjacent second cylindrical rollers, and all the second cylindrical rollers rotate synchronously through the second drive chain.

[0021] As a preferred embodiment of the present invention, the synchronous transmission assembly includes a fixed gear disposed on the first cylindrical roller on the outermost side, and a synchronous chain disposed on the fixed gear. A second cylindrical roller directly above the first cylindrical roller is provided with a separate combined wheel inside the hollow track plate. The fixed gear and the separate combined wheel rotate synchronously in the same direction through the synchronous chain.

[0022] As a preferred embodiment of the present invention, a support panel is provided below the track panel, and the track panel is hinged to the support panel. The two sides of the support panel are respectively installed on each of the open track panels by a plurality of evenly distributed reinforcing rods.

[0023] The open track plate is equipped with a tensioning wheel, which adaptively adjusts the tension of the synchronous chain according to the inclination state of the upper roller conveyor, so that the redundant length of the synchronous chain meets the inclination requirements of the upper roller conveyor.

[0024] As a preferred embodiment of the present invention, when the separate combined wheel is a whole, the first cylindrical roller drives the second cylindrical roller to rotate through the synchronous chain, and all the second cylindrical rollers rotate synchronously and in the same direction with the first cylindrical roller through the second transmission chain;

[0025] When the second cylindrical roller separates into two wheel bodies, the second cylindrical roller remains stationary independently of the first cylindrical roller.

[0026] As a preferred embodiment of the present invention, the separable combined wheel includes a rotating gear mounted on the end of the second cylindrical roller, and a cylindrical insert wheel mounted on the second cylindrical roller and disposed inside the rotating gear. The opposing surfaces of the rotating gear and the cylindrical insert wheel are respectively provided with a protrusion and a groove that can be fitted together. The rotating gear and the cylindrical insert wheel are combined into a whole by the protrusion and the groove, and the protrusion and the groove of the rotating gear and the cylindrical insert wheel form independent individuals when separated.

[0027] In a preferred embodiment of the present invention, the rotating gear is fixedly mounted on the second cylindrical roller, and the cylindrical insert is movably mounted on the second cylindrical roller. The end side curved surface of the second cylindrical roller is provided with a plurality of evenly distributed recessed grooves. The inner surface of the cylindrical insert is mounted in the recessed grooves by a locking block and moves along the inner and outer limits of the recessed grooves.

[0028] As a preferred embodiment of the present invention, the outer surface of the cylindrical insert is provided with a rotating body capable of rotating around the cylindrical insert, and at least two return springs are provided between the side curved surface of the rotating body and the side edge of the support panel.

[0029] When the second cylindrical roller rotates to an inclined state, the return spring drives the cylindrical insert to move towards the inside of the second cylindrical roller, so that the rotating gear and the cylindrical insert separate, and the second cylindrical roller remains stationary independently of the first cylindrical roller.

[0030] When the second cylindrical roller returns to a horizontal position, the reset spring drives the cylindrical insert to move outward of the second cylindrical roller, so that the rotating gear and the cylindrical insert combine, and the second cylindrical roller rotates synchronously with the first cylindrical roller.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] This invention utilizes a lifting double-layer roller conveyor for lifting and removing waste slabs, as well as for normal conveying of multi-layer stacked gypsum boards. The lifting double-layer roller conveyor uses a single power drive component, which reduces the number of power drive components required, reduces the area occupied, ensures the normal conveying function of the lower roller conveyor, saves energy, and ensures that the conveying speed of the two roller conveyors is exactly the same.

[0033] In addition, the upper roller conveyor of the present invention is adjusted to an inclined state to automatically remove waste by utilizing the gravitational potential energy of the gypsum board, thereby improving waste removal efficiency and reducing the probability of board breakage.

[0047] 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.

[0048] like Figure 1 As shown, this invention provides a single-layer board flipping waste disposal system for a gypsum board production line. During the gypsum board production process, sometimes single-layer boards appear, and multiple sets of single boards enter the stacking platform. In this case, it is necessary to manually confirm the number of boards in the whole stack, which consumes a lot of manpower. In order to solve the above problem, this embodiment detects the stacking thickness of the conveyed gypsum boards, determines whether there is a single board being conveyed based on the stacking thickness, and then disposes of the single board as waste.

[0049] The single-board automatic waste disposal system specifically includes a first conveying and detection system 1, a second conveying and waste disposal system 2, and a waste stacking platform 3.

[0050] The first conveying and detection system 1 is used to convey gypsum board, and at the same time, it uses multiple detection modules arranged above the gypsum board and distributed along the width direction of the gypsum board to detect the thickness of the gypsum board in real time.

[0051] When the slit gypsum board passes through the belt conveyor of the first conveying and detection system 1, the detection module monitors its thickness to determine whether the board meets the requirements for edging. Specifically, the distance between the installation position of the detection module and the belt conveyor is a fixed value. Based on the distance measurement value fed back by the detection module, the stack thickness of the slit gypsum board is obtained. When the stack thickness of the gypsum board is expressed as the thickness of a single gypsum board, the second conveying and waste disposal system 2 is used to transfer the single gypsum board to the waste stacking platform 3.

[0052] The second waste conveying system 2 is used to continue conveying gypsum board, and during the conveying process, it will lift and discharge waste from individual gypsum boards with a thickness indicated by the thickness of the board.

[0053] The waste stacking platform 3 is located on the side of the second waste conveying system 2 and is used to receive and convey the waste gypsum board.

[0054] It should be noted that the first conveying and detection system 1 and the second conveying and waste discharge system 2 are connected to a PLC system. When the detection module detects that the board does not meet the board feeding requirements, it transmits the waste discharge signal to the PLC system. At this time, the PLC system controls the second conveying and waste discharge system 2 to lift the single gypsum board to a high position and automatically transfer the unqualified board to the waste stacking platform 3.

[0055] Once a set of waste boards has been discharged, the PLC system automatically controls the second waste conveying system 2 to descend and switch to normal operation, transferring the qualified boards to the edge-wrapping station.

[0056] As can be seen from the above, the second waste conveying system 2 includes a conveying roller conveyor 21 and a lifting double-layer roller conveyor 22 disposed between the conveying roller conveyors 21.

[0057] In this embodiment, the lifting double-layer roller conveyor 22 is divided into an upper roller conveyor 4 and a lower roller conveyor 5. Under normal working conditions, the upper roller conveyor 4 conveys gypsum boards with a thickness exceeding that of a single veneer. When a single veneer gypsum board is present, the upper roller conveyor 4 and the lower roller conveyor 5 of the lifting double-layer roller conveyor 22 are simultaneously lifted. The upper roller conveyor 4 of the lifting double-layer roller conveyor 22 is used to lift up the gypsum boards that need to be disposed of, and the lower roller conveyor 5 of the lifting double-layer roller conveyor 22 is used to continue conveying gypsum boards that do not need to be disposed of.

[0058] To achieve the function of conveying gypsum board, existing technologies also use a lifting double-layer roller conveyor 22 for waste discharge and continued conveying. However, most existing lifting double-layer roller conveyors 22 use two power components, namely one power component for the upper roller conveyor 4 and one power component for the lower roller conveyor 5. On the one hand, this results in high noise, low energy utilization, and relatively complex control logic. On the other hand, the installation position of the power component of the upper roller conveyor 4 needs to be specially set to avoid affecting the normal conveying of gypsum board by the lower roller conveyor 5.

[0059] In order to solve the problems existing in the prior art, in this embodiment, the upper roller 4 and the lower roller 5 of the lifting double-layer roller conveyor 22 share the same power drive component 23, and the power drive component 23 drives the lifting double-layer roller conveyor 22 to rotate synchronously.

[0060] The power drive assembly 23 is installed on the lower roller conveyor 5, and the power drive assembly 23 directly drives the lower roller conveyor 5 to rotate in the same direction as the conveyor roller conveyor 21.

[0061] The upper roller conveyor 4 and the lower roller conveyor 5 are connected by a synchronous transmission assembly 24. The upper roller conveyor 4 rotates synchronously and in the same direction with the lower roller conveyor 5 using the synchronous transmission assembly 24.

[0062] That is, in the implementation method, such as Figure 2 As shown, the power drive component 23 directly drives the lower roller conveyor 5, and the upper roller conveyor 4 and the lower roller conveyor 5 of the lifting double-layer roller conveyor 22 can be driven separately through the synchronous transmission component 24. Thus, the upper roller conveyor 4 and the lower roller conveyor 5 share the same power drive component 23. When the lower roller conveyor 5 is conveying gypsum board that normally requires edge wrapping, the installation position of the power drive component 23 will not obstruct the conveying of the gypsum board.

[0063] In addition, as another innovation of this embodiment, a stripping cylinder 25 for pushing the upper roller 4 to tilt is installed below the upper roller 4 of the lifting double-layer roller conveyor 22. The stripping cylinder 25 moves up and down synchronously with the lifting double-layer roller conveyor 22, and pushes the upper roller 4 to tilt independently when the lifting double-layer roller conveyor 22 is raised to its maximum height, so that the gypsum board raised by the upper roller 4 is transferred to the waste stacking platform 3. The lower roller 5 remains stationary by separating from the upper roller 4 during the waste discharge operation.

[0064] Since the upper roller conveyor 4 and the lower roller conveyor 5 share the same power drive component 23, when the upper roller conveyor 4 and the lower roller conveyor 5 are lifted at the same time, the upper roller conveyor 4 can also maintain dynamic conveying operation. However, since the upper roller conveyor 4 is in an inclined state at this time, the waste gypsum board veneer falls into the waste stacking platform 3 in an inclined state under its own weight and the drive of the roller conveyor. The gypsum board on the waste stacking platform 3 cannot be aligned, which may cause secondary damage.

[0065] In this embodiment, although the upper roller conveyor 4 and the lower roller conveyor 5 share the same power drive component 23, when the upper roller conveyor 4 and the lower roller conveyor 5 are lifted at the same time, the upper surface of the lower roller conveyor 5 is flush with the upper surface of the conveying roller conveyor 21, and the upper roller conveyor 4 is pushed to an inclined state by the unloading cylinder 25. At this time, the upper roller conveyor 4 and the lower roller conveyor 5 are driven separately. The lower roller conveyor 5 maintains dynamic conveying operation, but the upper roller conveyor 4 is stationary. Thus, the gypsum board is transferred from the inclined upper roller conveyor 4 to the waste stacking platform 3.

[0066] The specific implementation structure for the upper roller conveyor 4 and the lower roller conveyor 5 to use the same power drive component 23 is as follows:

[0067] The lower roller conveyor 5 includes two open track plates 51 at the front and rear, and a plurality of first cylindrical rollers 52 evenly arranged inside the two open track plates 51. The same end of all the first cylindrical rollers 52 is mounted inside the open track plate 51 by bearings, and the other end of all the first cylindrical rollers 52 is connected by a first transmission chain 53 arranged between two adjacent first cylindrical rollers 52.

[0068] The power drive assembly 23 includes a drive motor 231 located below the open track plate 51 and a drive chain 232 located on the output wheel of the drive motor 231. A synchronous rotating wheel 233 is provided on the first cylindrical roller 52 located away from the waste stacking platform 3 and on the outermost side. The drive chain 232 is located between the synchronous rotating wheel 233 and the output wheel of the drive motor 231. The power drive assembly 23 drives the first cylindrical roller 52 located on the outermost side to rotate through the drive chain 232, and all the first cylindrical rollers 52 rotate synchronously through multiple first transmission chains 53.

[0069] It should be noted that a lifting platform is provided below the lower roller conveyor 5. The lifting platform supports the open track plate 51 and is fixed to the open track plate 51, driving the open track plate 51 and the power drive assembly 23 to lift and lower simultaneously.

[0070] The lifting and lowering distance of the lifting platform is the distance between the upper roller conveyor 4 and the lower roller conveyor 5, so that when the lower roller conveyor 5 is lifted, it is flush with the conveyor roller conveyor 21, and when it is lowered, the upper roller conveyor 4 is flush with the conveyor roller conveyor 21.

[0071] The principle behind the synchronous and unidirectional rotation of the first cylindrical roller 52 driven by the power drive component 23 is as follows:

[0072] The drive motor 231 drives the first cylindrical roller 52, which is far away from the waste stacking platform 3 and located on the outermost side, to rotate first through the meshing action of the drive chain 232 and the synchronous rotating wheel 233. The other first cylindrical rollers 52 rotate synchronously through the first transmission chain 53 between two adjacent first cylindrical rollers 52, so that all the first cylindrical rollers 52 achieve synchronous and unidirectional rotation.

[0073] The upper roller conveyor 4 includes a track panel 41 close to the waste stacking platform 3, a hollow track plate 42 away from the waste stacking platform 3, and a plurality of second cylindrical rollers 43 evenly arranged between the track panel 41 and the hollow track plate 42. One end of all the second cylindrical rollers 43 is mounted on the track panel 41 through a bearing seat, and the other end of all the second cylindrical rollers 43 is mounted on the side panel of the hollow track plate 42 through a bearing ring.

[0074] All the ends of the second cylindrical rollers 43 inside the hollow track plate 42 are connected by a second transmission chain 44 disposed between two adjacent second cylindrical rollers 43, and all the second cylindrical rollers 43 rotate synchronously through the second transmission chain 44.

[0075] The synchronous transmission assembly 24 includes a fixed gear 241 disposed on the outermost first cylindrical roller 52 on the other side, and a synchronous chain 242 disposed on the fixed gear 241. The second cylindrical roller 43 directly above the first cylindrical roller 52 has a separate combined wheel 7 inside the hollow track plate 42. The fixed gear 241 and the separate combined wheel 7 rotate synchronously in the same direction through the synchronous chain 242.

[0076] The first cylindrical roller 52 and the second cylindrical roller 43 directly above it rotate synchronously in the same direction via a synchronous chain 242. The other second cylindrical rollers 43 rotate synchronously via a second transmission chain 44 between adjacent second cylindrical rollers 43, so that all the second cylindrical rollers 43 achieve synchronous rotation in the same direction.

[0077] Therefore, in this embodiment, the power drive component 23 first drives the outermost first cylindrical roller 52 to rotate, and every two first cylindrical rollers 52 are driven by the first transmission chain 53, gradually making all the first cylindrical rollers 52 rotate synchronously in the same direction.

[0078] Finally, the outermost first cylindrical roller 52 and the second cylindrical roller 43 directly above it are driven by a synchronous chain 242. Specifically, the fixed gear 241 on the first cylindrical roller 52 is driven by a separate combination wheel 7 of the second cylindrical roller 43 directly above it via a synchronous chain 242. At this time, the outermost second cylindrical roller 43 rotates in the same direction as the first cylindrical roller 52.

[0079] Every two second cylindrical rollers 43 are driven by the second transmission chain 44, gradually causing all the second transmission chains 44 to rotate synchronously in the same direction. Their rotation direction is the same as that of the first cylindrical roller 52 and the same as that of the conveyor roller table 21.

[0080] Therefore, in this embodiment, the upper roller conveyor 4 and the lower roller conveyor 5 share the same power drive component 23 to rotate synchronously in the same direction. Since the power drive component 23 is located below the lower roller conveyor 5, the power drive component 23 will not hinder the normal conveying of the lower roller conveyor 5. Using only one power drive component 23 to drive the upper roller conveyor 4 and the lower roller conveyor 5 can reduce the space occupied by the drive component, reduce energy consumption, and simplify the control logic.

[0081] When the upper roller conveyor 4 and the lower roller conveyor 5 are simultaneously raised to their highest positions, the unloading cylinder 25 pushes the upper roller conveyor 4 to tilt, and the veneer gypsum board is transferred from the tilted upper roller conveyor 4 to the waste stacking platform 3, which improves waste discharge efficiency and reduces the probability of board breakage.

[0082] like Figure 3 As shown, the upper roller conveyor 4 has an inclined structure as follows: a support panel 45 is provided below the track panel 41, and the track panel 41 is hinged to the support panel 45. The two sides of the support panel 45 are respectively installed on each open track plate 51 by multiple evenly distributed reinforcing rods 46.

[0083] The unloading cylinder 25 specifically pushes the track panel 41 of the upper roller conveyor 4 to tilt around the support panel 45. At this time, the gypsum board falls from the side of the track panel 41 to the waste stacking platform 3. Since the gypsum board has dried and formed at this time, the bearing seat on the track panel 41 will not damage the gypsum board.

[0084] When the upper roller conveyor 4 is pushed to an inclined state, the hollow track plate 42 of the upper roller conveyor 4 is raised. In order to achieve normal transmission operation, a tensioning wheel 6 is provided on the open track plate 51. The tensioning wheel 6 adaptively adjusts the tension of the synchronous chain 242 according to the inclined state of the upper roller conveyor 4 so that the redundant length of the synchronous chain 242 meets the inclined requirements of the upper roller conveyor 4.

[0085] As can be seen from the above, when the upper roller conveyor 4 is pushed to an inclined state, the upper roller conveyor 4 and the lower roller conveyor 5 are separated and driven. The upper roller conveyor 4 becomes stationary, while the lower roller conveyor 5 continues to operate and transport multi-layer gypsum board under the drive of the power drive component 23.

[0086] When the upper roller conveyor 4 returns to a horizontal position and descends to be flush with the conveyor roller conveyor 21, the upper roller conveyor 4 and the lower roller conveyor 5 rotate synchronously in the same direction. At this time, the upper roller conveyor 4 resumes normal conveying operation.

[0087] Specifically, when the split combination wheel 7 is a whole, the first cylindrical roller 52 drives the second cylindrical roller 43 to rotate through the synchronous chain 242, and all the second cylindrical rollers 43 rotate synchronously and in the same direction with the first cylindrical roller 52 through the second transmission chain 44.

[0088] When the split-type combined wheel 7 separates into two wheel bodies from the second cylindrical roller 43, the second cylindrical roller 43 remains stationary independently of the first cylindrical roller 52.

[0089] In this embodiment, the split-type combined wheel 7 can automatically adjust and separate into two wheel bodies according to the tilt state of the second cylindrical roller 43. That is, when the second cylindrical roller 43 is tilted, the split-type combined wheel 7 can automatically separate into two wheel bodies. The second cylindrical roller 43 remains stationary independently of the first cylindrical roller 52. When the second cylindrical roller 43 returns to a horizontal state, the split-type combined wheel 7 automatically forms a whole. The second cylindrical roller 43 and the first cylindrical roller 52 are driven by meshing with the synchronous chain 242.

[0090] Therefore, as Figure 4 As shown, the specific structure of the split combination wheel 7 is as follows:

[0091] The split-type combined wheel 7 includes a rotating gear 71 installed at the end of the second cylindrical roller 43, and a cylindrical insert wheel 72 installed on the second cylindrical roller 43 and disposed inside the rotating gear 71. The opposite surfaces of the rotating gear 71 and the cylindrical insert wheel 72 are respectively provided with a protrusion 73 and a groove 74 that can be fitted together. The rotating gear 71 and the cylindrical insert wheel 72 are combined into a whole by the protrusion 73 and the groove 74, and when the protrusion 73 and the groove 74 of the rotating gear 71 and the cylindrical insert wheel 72 are separated, they form independent individuals.

[0092] The rotating gear 71 is movably mounted on the second cylindrical roller 43, and the cylindrical insert 72 is fixedly mounted on the second cylindrical roller 43. The end side curved surface of the second cylindrical roller 43 is provided with a plurality of evenly distributed recessed grooves 8. The inner surface of the cylindrical insert 72 is mounted in the recessed groove 8 by means of a locking block 9 and moves along the inner and outer limits of the recessed groove 8.

[0093] The outer surface of the cylindrical insert 72 is provided with a rotating body 10 that can rotate around the cylindrical insert 72, and at least two return springs 11 are provided between the side curved surface of the rotating body 10 and the side edge of the support panel 45.

[0094] When the second cylindrical roller 43 rotates to the tilted state, the return spring 11 drives the cylindrical insert 72 to move towards the inside of the second cylindrical roller 43, so that the rotating gear 71 and the cylindrical insert 72 separate, and the second cylindrical roller 43 remains stationary independently of the first cylindrical roller 52.

[0095] When the second cylindrical roller 43 is reset to the horizontal state, the return spring 11 drives the cylindrical insert wheel 72 to move outward of the second cylindrical roller 43, so that the rotating gear 71 and the cylindrical insert wheel 72 are combined, and the second cylindrical roller 43 rotates synchronously with the first cylindrical roller 52.

[0096] Therefore, in this embodiment, a lifting double-layer roller conveyor is used to lift and discharge single boards and to transport multi-layer stacked gypsum boards normally. The lifting double-layer roller conveyor uses a single power drive component, which can reduce the number of power drive components used, reduce the occupied area, ensure the normal transport function of the lower roller conveyor, save energy, and at the same time ensure that the transport speed of the two roller conveyors is exactly the same.

[0097] In addition, the upper roller conveyor in this embodiment is adjusted to an inclined state, which utilizes the gravitational potential energy of the gypsum board to perform automatic waste removal, thereby improving waste discharge efficiency and reducing the probability of board breakage.

[0098] In order to achieve fixed-point waste removal, the upper roller conveyor is separated from the lower roller conveyor. The lower roller conveyor is kept in operation and conveying state, while the upper roller conveyor is kept stationary. In this way, the waste discharge position is always fixed, avoiding damage to the gypsum board from which the waste is discharged.

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.
