Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board conveying, and particularly relates to an adaptive variable-speed conveying roller path for gypsum boards. Background Art

[0002] During the production process of gypsum boards, various production factors affect the final quality of the gypsum boards. Therefore, it is necessary to measure the corresponding parameters of the gypsum boards to detect whether the corresponding production factors meet the standards. For example, if the surface temperature of the gypsum board is too high or too low after final setting, it will cause problems such as non-sticking of the facing paper, board cracking, and energy consumption loss. Or if the board temperature of the board after drying by the dryer is too low or overheated, it will result in poor quality of the gypsum board.

[0003] In this regard, infrared temperature sensors are usually set on the gypsum board conveyor line to measure the temperature of the gypsum board surface. To reduce costs, a single or a small number of infrared temperature sensors are used instead of the design of setting infrared temperature sensors on each layer. The infrared temperature sensors poll and scan the temperature, and collect temperature data for the corresponding layer where the gypsum board enters.

[0004] When there are gypsum boards entering multiple layers at the same time during the polling temperature acquisition technology, it is necessary to collect the temperature of the corresponding layer in sequence. When the temperature acquisition time is fixed, it is possible that the polling temperature acquisition work has not reached the corresponding layer after the gypsum board is discharged, resulting in the situation that the temperature is not collected in time. It is also possible to set a stop device at the discharge end of the gypsum board conveyor line to stop the gypsum board that has not been temperature measured. The conveyor line is still running, causing continuous sliding friction between the conveyor line and the contact end face of the gypsum board, and wearing the surface of the gypsum board in contact with the conveyor line. Summary of the Invention

[0005] Therefore, the present invention provides an adaptive variable-speed conveying roller path for gypsum boards, which effectively solves the problems that the polling temperature acquisition work has not reached the corresponding layer after the gypsum board is discharged in the prior art, resulting in the temperature not being collected in time, and the stop device stops the gypsum board that has not been temperature measured, causing continuous sliding friction between the conveyor line and the contact end face of the gypsum board, thereby wearing the surface of the gypsum board in contact with the conveyor line.

[0046] 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.

[0047] As Figure 1 and Figure 2 shown, the present invention provides an adaptive variable - speed conveyor roller path for gypsum boards, which has a multi - layer roller conveyor device 1, a variable - speed conveyor drive 2, a link transmission device 3, and a variable - speed drive device 4.

[0048] Among them, the multi - layer roller conveyor device 1 is arranged at the discharging end of the loading roller path 5. There are several conveyor rollers 11 arranged in the multi - layer roller conveyor device 1. The multi - layer roller conveyor device 1 decelerates and transports the gypsum boards entering the multi - layer roller conveyor device 1 through the conveyor rollers 11 at a gypsum board transportation speed less than the transportation speed of the loading roller path 5. The multi - layer roller conveyor device 1 includes a deceleration transportation section and an acceleration transportation section. The loading roller path 5 is a transportation device that transports gypsum boards onto the multi - layer roller conveyor device 1.

[0049] The variable-speed conveying drive member 2 is arranged at the loading end and the unloading end of the multi-layer roller conveyor 1. The variable-speed conveying drive member 2 is used for driving connection with the deceleration conveying section and the acceleration conveying section, so that the variable-speed conveying drive member 2 drives the multi-layer roller conveyor 1 to sequentially perform deceleration conveying and acceleration conveying on the gypsum board in sections.

[0050] The link transmission device 3 is connected to the side of the multi-layer roller conveyor 1. The link transmission device 3 is used to establish the connection relationship between the variable-speed conveying drive member 2 and the conveying roller 11, so as to drive the conveying roller 11 to rotate and convey through the variable-speed conveying drive member 2, and establish the connection relationship between adjacent conveying rollers 11, so as to drive the adjacent conveying rollers 11 to rotate and convey through the conveying roller 11.

[0051] The variable-speed drive device 4 is correspondingly arranged on the conveying roller 11 and is connected to the link transmission devices 3 on the adjacent two sides. The variable-speed drive device 4 is used to cut off the connection relationship between the previous link transmission device 3 and the conveying roller 11 at the current position, so that the conveying roller 11 at the corresponding position is driven by the latter conveying roller 11 through the latter link transmission device 3 to drive and rotate for conveying. The variable-speed drive device 4 is used to cut off the connection relationship between the link transmission devices 3 on the adjacent two sides and the conveying roller 11, so that the corresponding conveying roller 11 is in a braking state.

[0052] In the embodiment of the present invention, the variable-speed conveying drive member 2 drives the multi-layer roller conveyor 1 to sequentially perform deceleration conveying and acceleration conveying on the gypsum board in sections, and the variable-speed drive device 4 divides the corresponding deceleration conveying section and acceleration conveying section, or directly cuts off the connection relationship between the link transmission devices 3 on the adjacent two sides and the conveying roller 11, so that the corresponding conveying roller 11 is in a braking state. The variable-speed drive device 4 brakes the conveying of the gypsum board and accelerates the conveying of the gypsum board after the temperature detection is completed, avoiding the accumulation of the gypsum board caused by deceleration conveying, and ensuring the timely temperature detection of the gypsum board by controlling the conveying speed and conveying state of the gypsum board.

[0053] In the present invention, the multi-layer roller conveyor 1 is used to convey the gypsum board. The multi-layer roller conveyor 1 is composed of a plurality of roller layers 12. The conveying rollers 11 are sequentially and equidistantly installed in the roller layers 12; a driving shaft 13 is coaxially arranged on the conveying roller 11, and the conveying roller 11 is rotationally installed on the roller layer 12 through the driving shaft 13.

[0054] In the above embodiment, the temperature detection device 6 arrives at the corresponding roller layer 12 in sequence to measure the temperature of the gypsum board on the corresponding layer. The present invention can be applied not only in the polling temperature detection process, but also in the process of detecting other parameters.

[0055] In the present invention, the variable-speed conveying driving member 2 is in transmission connection with the decelerating conveying section and the accelerating conveying section, so that the variable-speed conveying driving member 2 drives the multi-layer roller conveying device 1 to sequentially perform decelerating conveying and accelerating conveying on the gypsum board in sections. The following preferred embodiments are adopted for the variable-speed conveying driving member 2 of the present invention. The variable-speed conveying driving member 2 includes a decelerating driving motor 21 arranged on the side of the conveying roller 11 at the feeding end, a first driving column 22 connected to the output end of the decelerating driving motor 21, an accelerating driving motor 23 arranged on the side of the conveying roller 11 at the discharging end, and a second driving column 24 connected to the output end of the accelerating driving motor 23. Both the first driving column 22 and the second driving column 24 are connected to the link transmission device 3.

[0056] In the above embodiment, the decelerating driving motor 21 drives the first driving column 22 to rotate, thereby driving the corresponding conveying roller 11 to rotate. The accelerating driving motor 23 drives the second driving column 24 to rotate, thereby driving the corresponding conveying roller 11 to rotate. In this embodiment, the driving speeds of the decelerating driving motor 21 and the accelerating driving motor 23 are different.

[0057] In addition, the first driving column 22 and the driving shaft 13 are in transmission connection through the link transmission device 3, and the second driving column 24 and the driving shaft 13 are also in transmission connection through the link transmission device 3. The area corresponding to the transmission connection with the decelerating driving motor 21 is the decelerating conveying section, and the area corresponding to the transmission connection with the accelerating driving motor 23 is the accelerating conveying section. Usually, when the temperature of the gypsum board is not detected at the beginning, all of the multi-layer roller conveying device 1 is in transmission connection with the decelerating driving motor 21, that is to say, all are the decelerating conveying section. After the gypsum board passes the temperature detection, the variable-speed driving device 4 needs to cut off the connection relationship between the previous link transmission device 3 and the conveying roller 11 at the current position, so that the conveying roller 11 at the corresponding position is driven to rotate and convey by the subsequent conveying roller 11 through the subsequent link transmission device 3. That is to say, the current conveying roller 11 is driven by the accelerating driving motor 23 located behind to perform accelerating conveying.

[0058] In addition, when the temperature detection is not performed when the gypsum board reaches the end of the multi-layer roller conveying device 1, the variable-speed driving device 4 needs to be driven to cut off the connection relationship between the link transmission devices 3 on the adjacent sides and the conveying roller 11, so that the corresponding conveying roller 11 is in a braking state and the conveying action of the gypsum board is stopped until the gypsum board completes the temperature detection.

[0059] In order to prevent the gypsum board from piling up during the conveying process, the present invention also makes the following design. The driving speed of the driving end of the loading roller path 5 is V1, the driving speed of the decelerating driving motor 21 is V2, and the driving speed of the accelerating driving motor 23 is V3; wherein, V3 is greater than V1, and V1 is greater than V2.

[0060] In the above embodiments, the gypsum board is driven by the deceleration drive motor 21 for decelerated transportation. After a period of decelerated transportation, it is very likely to cause congestion with the gypsum boards transported from the rear. Therefore, the acceleration drive motor 23 can transport the gypsum board at a faster transportation speed, avoiding the accumulation and congestion during the transportation of the gypsum board.

[0061] The present invention establishes the connection relationship between the variable-speed conveying driving member 2 and the conveying roller 11 through the link transmission device 3, so as to drive the conveying roller 11 to rotate and transport through the variable-speed conveying driving member 2, and establish the connection relationship between adjacent conveying rollers 11, so as to drive the adjacent conveying rollers 11 to rotate and transport through the conveying roller 11. The link transmission device 3 of the present invention adopts the following preferred embodiments, such as Figure 3 As shown, the link transmission device 3 includes a first driving sprocket 31 arranged on the first driving column 22 and the second driving column 24, a linkage cylinder 32 connected and arranged on the driving shaft 13, an outer transmission cylinder 33 rotatably arranged at the end of the driving shaft 13, and a toothed chain 34 arranged on the first driving sprocket 31; a first transmission sprocket 35 is arranged on the outer transmission cylinder 33, and the toothed chain 34 is meshed with the first transmission sprocket 35, and a limit seat 36 is fixedly arranged at the end of the driving shaft 13.

[0062] In the above embodiments, the first driving sprocket 31 can drive the first transmission sprocket 35 to rotate through the toothed chain 34, thereby driving the outer transmission cylinder 33 to rotate. The outer transmission cylinder 33 can drive the driving shaft 13 to rotate through the variable-speed drive device 4, thereby driving the conveying roller 11 to rotate.

[0063] The above structure can enable the first driving column 22 and the second driving column 24 to drive the driving shaft 13 to rotate. In order to drive the adjacent driving shafts 13 to rotate through the driving shaft 13, the present invention also makes the following design, such as Figure 3 and Figure 4 As shown, an inner transmission cylinder 39 is rotatably arranged on the driving shaft 13, a second transmission sprocket 37 is arranged on the inner transmission cylinder 39, and the second transmission sprockets 37 on the sides of adjacent conveying rollers 11 are connected by a toothed chain 34 in transmission; a limit rotating groove 310 for the inner transmission cylinder 39 to rotate is arranged on the driving shaft 13.

[0064] In the above embodiments, the rotation of the driving shaft 13 can drive the inner transmission cylinder 39 to rotate, and the inner transmission cylinder 39 can drive the second transmission sprocket 37 to rotate, thereby driving the second transmission sprocket 37 on the corresponding conveying roller 11 to rotate through the toothed chain 34, and driving the adjacent driving shafts 13 to rotate through the second transmission sprocket 37.

[0065] In the embodiment of the present invention, the connection relationship between the inner transmission cylinder 39 and the driving shaft 13 determines the transmission connection between the current conveying roller 11 and the next conveying roller 11, and the connection relationship between the inner transmission cylinder 39 and the driving shaft 13 determines the transmission connection relationship between the current conveying roller 11 and the previous conveying roller 11. The above-mentioned transmission connection relationship is adjustable and can be adjusted by the variable-speed driving device 4. Therefore, the following design is made in the present invention. Clamping members 38 are provided on both the inner transmission cylinder 39 and the outer transmission cylinder 33. The end of the clamping member 38 is clamped on the linkage cylinder 32. When the driving shaft 13 rotates, the inner transmission cylinder 39 and the outer transmission cylinder 33 are driven to be connected through the linkage cylinder 32 and the clamping member 38. The clamping member 38 is provided with at least one.

[0066] The inner transmission cylinder 39 is connected to the driving shaft 13 through the clamping member 38, and the outer transmission cylinder 33 is connected to the driving shaft 13 through the clamping member 38. In this embodiment, when the clamping member 38 is clamped on the driving shaft 13, it indicates that the transmission connection relationship between the two is established, and vice versa, the transmission connection relationship between the two is released.

[0067] The clamping state of the clamping member 38 of the present invention is adjustable. The following preferred embodiment is adopted for the clamping member 38 of the present invention, as Figure 5 , Figure 6 and Figure 7 shown, the clamping member 38 includes an elastic mounting plate 381 provided outside the inner transmission cylinder 39 and the outer transmission cylinder 33, an elastic convex plate 382 connected to the end of the elastic mounting plate 381, an inner concave clamping plate 383 connected to the end of the elastic convex plate 382, and a lifting end plate 384 connected to the end of the inner concave clamping plate 383; the elastic mounting plate 381 is mounted on the outer walls of the inner transmission cylinder 39 and the outer transmission cylinder 33 through mounting bolts 385.

[0068] In order to enable the driving shaft 13 to be clamped and connected with the above structure, a clamping groove 386 is provided outside the linkage cylinder 32. The clamping groove 386 corresponds to the clamping member 38. The inner concave clamping plate 383 extends inward into the clamping groove 386, and the lifting end plate 384 extends out of the clamping groove 386, and the end of the lifting end plate 384 is flush with the outer wall of the linkage cylinder 32.

[0069] In the above embodiment, the elastic mounting plate 381, the elastic convex plate 382, and the inner concave clamping plate 383 are all made of spring sheet material and can change their positions. However, due to the fixation of the mounting bolts 385, the elastic mounting plate 381 is always mounted on the inner transmission cylinder 39 and the outer transmission cylinder 33. In the initial state, the inner concave clamping plate 383 is clamped in the clamping groove 386. Therefore, the inner transmission cylinder 39, the outer transmission cylinder 33, and the linkage cylinder 32 are in a clamped state. At this time, the driving shaft 13 at the current position can rotate and transmit under the driving action of the previous driving shaft 13, and can also drive the subsequent driving shaft 13 to rotate and transmit under its own driving action.

[0070] When the clamping state between the clamping member 38 on the inner transmission cylinder 39 and the drive shaft 13 is cut off, it indicates that the current drive shaft 13 cannot drive the subsequent drive shaft 13 to rotate. When the clamping state between the clamping member 38 on the outer transmission cylinder 33 and the drive shaft 13 is cut off, it indicates that the current drive shaft 13 cannot perform rotational transmission under the driving action of the previous drive shaft 13. When the clamping states between the clamping members 38 on the inner transmission cylinder 39 and the outer transmission cylinder 33 and the drive shaft 13 are simultaneously cut off, it indicates that the drive shaft 13 cannot establish a transmission connection relationship with the previous drive shaft 13 and the subsequent drive shaft 13, and is in a braking state.

[0071] The present invention mainly cuts off the clamping states between the clamping members 38 on the inner transmission cylinder 39 and the outer transmission cylinder 33 and the drive shaft 13 through the variable-speed drive device 4. The variable-speed drive device 4 of the present invention mainly adopts the following preferred embodiments, such as Figure 5 、 Figure 6 and Figure 7 shown. The variable-speed drive device 4 includes a mounting ring 41 provided on the linkage cylinder 32, drive cylinders 42 provided on both sides of the mounting ring 41, and a lifting ring seat 43 provided at the output end of the drive cylinders 42; the end of the lifting ring seat 43 extends between the lifting end plate 384 and the linkage cylinder 32.

[0072] In the above embodiment, the drive cylinder 42 drives the lifting ring seat 43 to approach between the lifting end plate 384 and the linkage cylinder 32, and the lifting ring seat 43 gradually drives the lifting end plate 384 to move upward, so that the concave clamping plate 383 disengages from the clamping groove 386.

[0073] The concave clamping plate 383 abuts against the outer wall of the lifting ring seat 43. In order to prevent the concave clamping plate 383 from being driven to rotate due to static friction during the rotation of the lifting ring seat 43, the present invention also makes the following design: an embedding groove 44 is provided at the end of the lifting ring seat 43, and a rotating ring 45 is provided in the embedding groove 44; the lifting ring seat 43 moves outward so that the concave clamping plate 383 slides to the outside of the rotating ring 45.

[0074] In the above embodiment, when the lifting ring seat 43 moves outward, the concave clamping plate 383 moves to the outer wall of the lifting ring seat 43 and enters the outside of the rotating ring 45. Since the rotating ring 45 can rotate around the lifting ring seat 43, the clamping member 38 and the lifting ring seat 43 are in a relative movement state. That is to say, when the drive shaft 13 rotates, it will no longer drive the corresponding inner transmission cylinder 39 or outer transmission cylinder 33 to rotate through the clamping member 38.

[0075] In summary, the main implementation process of the present invention is as follows:

[0076] The multi-layer roller conveyor 1 decelerates the transportation of the gypsum board: such as Figure 5As shown, in the initial state, the drive shafts 13 within a single roller path layer 12 are all drivingly connected. The reduction drive motor 21 drives the first drive column 22 to rotate, thereby driving the corresponding conveying rollers 11 to rotate, and drives all the conveying rollers 11 through the link drive device 3 to decelerate the transportation of the gypsum board entering the roller path layer 12;

[0077] The temperature detection device 6 measures the temperature of the gypsum board: the temperature detection device 6 performs polling temperature acquisition on the roller path layer where the gypsum board enters;

[0078] The multi-layer roller path conveying device 1 accelerates the transportation of the gypsum board: as Figure 6 shown, the variable speed drive device 4 cuts off the connection relationship between the conveying roller 11 at the end of the gypsum board and the previous link drive device 3, so that the conveying roller 11 at the corresponding position is driven by the latter conveying roller 11 through the latter link drive device 3 to rotate and transport;

[0079] For the above actions, the following operations need to be performed: To cut off the driving connection relationship between the drive shaft 13 corresponding to the conveying roller 11 at the end of the gypsum board and the previous drive shaft 13, it is necessary to cut off the clamping state between the outer drive cylinder 33 at the current position and the drive shaft 13. The drive cylinder 42 on the side close to the outer drive cylinder 33 drives the lifting ring seat 43 to approach between the lifting end plate 384 and the linkage cylinder 32. The lifting ring seat 43 gradually drives the lifting end plate 384 to move upward, so that the concave clamping plate 383 disengages from the clamping groove 386, and the concave clamping plate 383 slides outside the rotating ring 45. The clamping member 38 and the lifting ring seat 43 are in a relative moving state, and the drive shaft 13 at the current position and the outer drive cylinder 33 are in a relative rotating state. At this time, the drive acceleration drive motor 23 drives the second drive column 24 to rotate, thereby driving the corresponding conveying rollers 11 to rotate to accelerate the transportation of the gypsum board;

[0080] During the above implementation process, the cut-off position of the driving connection relationship can be used as the demarcation line between the deceleration transportation section and the acceleration transportation section. That is to say, the conveying rollers 11 including the conveying roller 11 where the gypsum board is located and those behind the gypsum board are all in the acceleration transportation section. The deceleration transportation section is driven by the deceleration drive motor 21, and the acceleration transportation section is driven by the acceleration drive motor 23. The transmission between the conveying rollers 11 at the ends of the deceleration transportation section and the acceleration transportation section is disconnected to avoid transmission interference.

[0081] Assume that the gypsum board is transported to the end of the multi-layer roller path conveying device 1 and the temperature has not been detected yet. Then, it is necessary to cut off the connection relationship between the conveying roller 11 at the position of the gypsum board and the link drive devices 3 on both adjacent sides, as Figure 7As shown, the driving cylinders 42 on both sides of the driving shaft 13 at the corresponding positions drive to drive the lifting ring seat 43 to approach between the lifting end plate 384 and the linkage cylinder 32. The lifting ring seat 43 gradually drives the lifting end plate 384 to move upward, so that the concave clamping plate 383 disengages from the clamping groove 386, and the concave clamping plate 383 slides outside the rotating ring 45. The clamping member 38 and the lifting ring seat 43 are in a relative movement state, and the driving shaft 13 at the current position and the outer transmission cylinder 33 are in a relative rotation state. The driving shaft 13 at the corresponding position of the gypsum board cannot establish a transmission connection relationship with the previous driving shaft 13 and the subsequent driving shaft 13, and is in a braking state until the temperature detection of the gypsum board is completed, the driving cylinder 41 is reset and the acceleration driving motor 23 is driven.

[0082] In the above embodiment, until the temperature detection of the gypsum board is completed, the driving cylinder 41 is reset and the acceleration driving motor 23 is driven. Among them, not all the driving cylinders 41 are reset. The driving cylinder 41 on the side of the driving shaft 13 on the conveying roller 11 at the end of the gypsum board close to the outer transmission cylinder 33 does not need to be reset. If it is reset, a transmission connection relationship will occur with the previous deceleration transportation section, causing transmission interference. It only needs to establish a transmission relationship with the acceleration driving motor 23 of the corresponding acceleration transportation section to accelerate the transportation of the gypsum board.

[0083] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
