Description

Technical Field

[0001] The present application relates to the technical field of gypsum board processing, and in particular to a conveying device for moisture-proof gypsum board processing. Background Art

[0002] Moisture-proof gypsum board is a kind of building board specially used in humid environment or requiring waterproof and moisture-proof. It is usually mixed with gypsum, cement, admixtures and other materials. The surface has undergone special waterproof treatment and has strong moisture-proof ability.

[0003] Due to the large size of moisture-proof gypsum board, during its production and processing, the moisture-proof gypsum board is generally laid flat on processing equipment or conveying equipment for processing, and after processing the upper surface of the moisture-proof gypsum board, it is often necessary to use a flip machine to turn the moisture-proof gypsum board over so that the upper and lower surfaces are reversed (that is, the originally downward side faces upward, and the originally upward side faces downward) so that the lower surface of the moisture-proof gypsum board can be processed accordingly.

[0004] Referring to the Chinese patent application document with publication number CN118597751A and publication date September 6, 2024, entitled A conveying device and method for gypsum board production, the friction surface of the conveyor belt provides an upward friction force to the entire gypsum board surface through the supporting effect of the support plate and the pushing pressure of the pushing unit on the gypsum board, thereby ensuring that the overall force on the gypsum board is uniform during the turning process, and reducing the possibility of internal cracking, deformation and distortion due to the influence of gravity and inertia during the turning process of the gypsum board.

[0005] Referring to the above technical solution, during the flipping process, the moisture-proof gypsum board often needs to be rolled on two-section flipping frames. During the actual flipping process, the moisture-proof gypsum board may still collide with the flipping frame due to inertia and gravity, thereby affecting the production quality of the moisture-proof gypsum board; and some moisture-proof gypsum boards may already be in a skewed state during feeding. In this case, the flipping operation is more likely to cause the corners of the moisture-proof gypsum board to collide with the flipping frame, which may cause the damage to the moisture-proof gypsum board to be aggravated. Summary of the invention

[0006] In view of this, the present application provides a conveying device for processing moisture-proof gypsum boards, which is mainly used to solve the problem that the moisture-proof gypsum boards may collide with the turning frame during the turning process, thereby affecting the production quality.

[0007] In order to solve the above technical problems, the present application provides a conveying device for moisture-proof gypsum board processing, including a frame and a conveying mechanism and a tensioning mechanism arranged inside the frame, the conveying mechanism is composed of a belt and four transmission rollers, and the four transmission rollers are respectively arranged at the four corners of the frame and connected by belt transmission, and the tensioning mechanism is used to adjust the tension of the belt; a swing arm is hingedly connected to the middle part of the frame, the swing arm is arranged in a U shape, and a swing roller capable of abutting the outer surface of the belt is rotatably connected to the bottom end of the swing arm, two bearing plates are slidably connected to the front and rear inner walls of the swing arm, and a plurality of first cylinders corresponding to the bearing plates one by one and used to drive the bearing plates to move independently are arranged on the swing arm, two guide rollers capable of abutting the inner surface of the belt are rotatably connected between every two front and rear corresponding bearing plates, and an air bag capable of being supplied or exhausted by an external air pump is arranged on the longitudinal arm beam at the bottom end of the swing arm; a driving member is arranged on the side wall of the frame, which is used to drive the swing arm to swing with its own hinge axis as a reference.

[0008] By adopting the above technical solution, the shape of the belt is changed by utilizing the cooperation of the swing arm and the guide roller to complete the turning over of the moisture-proof gypsum board, which can reduce the possibility of the moisture-proof gypsum board colliding with other components due to inertia and gravity.

[0009] Optionally, the tensioning mechanism includes two tensioning rollers slidably connected to the left and right ends of the frame respectively, and both tensioning rollers can abut against the outer surface of the belt. A tension spring is arranged inside the frame to enable the two tensioning rollers to have a tendency to approach each other.

[0010] By adopting the above technical solution, the tensioning roller can realize adaptive tensioning of the belt under the action of the tension spring, so as to prevent the belt from failing to hold force normally and affecting the conveying work.

[0011] Optionally, the driving member includes a servo motor arranged on a side wall of the frame, and the servo motor can cause the swing arm to swing in a belt drive manner.

[0012] Optionally, a brake assembly is provided at the bottom end of the swing arm, and the brake assembly is used to cooperate with the swing roller to clamp and lock the belt or unlock the belt.

[0013] Optionally, the brake assembly includes a second cylinder arranged at the bottom end of the swing arm, and the execution end of the second cylinder is provided with a pressure plate matching the swing roller, and the pressure plate can abut against the inner surface of the belt.

[0014] By adopting the above technical solution, during the turning over of the moisture-proof gypsum board, the belt is further clamped and locked by the pressure plate and the swing roller to prevent the belt from shifting during the turning over and affecting the clamping effect of the belt on the moisture-proof gypsum board.

[0015] Optionally, a cleaning assembly is provided on the longitudinal arm beam at the bottom end of the swing arm for cleaning the residue remaining on the outer surface of the belt.

[0016] Optionally, the cleaning assembly includes a scraper hinged on the longitudinal arm beam through a torsion spring, and the scraper is located on the side away from the feeding end of the belt, and the longitudinal arm beam is provided with a plurality of scraper holes that can be connected to an external dust suction device.

[0017] By adopting the above technical solution, the scraper can scrape off the residue that may be attached to the outer surface of the belt, and then the external vacuum device cooperates with the residue suction hole to extract the residue, thereby keeping the outer surface of the belt clean to prevent the residue from adhering to the outer surface of the belt and scratching the moisture-proof gypsum board that is subsequently transported.

[0018] Optionally, the scraper consists of a hollow knife sleeve and a scraper slidably connected to the inside of the hollow knife sleeve, and a spring is provided between the hollow knife sleeve and the scraper to enable the scraper to have a tendency to extend from the inside of the hollow knife sleeve.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 6 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0032] Reference Figure 1 and Figure 2 The present embodiment provides a conveying device for processing moisture-proof gypsum boards, comprising a frame 1, a conveying mechanism 2, a tensioning mechanism 3 and a turning mechanism. The conveying mechanism 2 comprises a belt 21 and four transmission rollers 22 respectively rotatably connected to the four corners of the frame 1, and the four transmission rollers 22 are connected by the belt 21; the tensioning mechanism 3 is used to adjust the tension of the belt 21.

[0033] Among them, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The flip mechanism includes a swing arm 4, a swing roller 41, a clamping assembly, an airbag 6 and a driving member 42. The swing arm 4 is U-shaped and hinged in the middle of the frame 1. The swing roller 41 is rotatably connected to the bottom end of the swing arm 4 and can abut against the outer surface of the belt 21; the clamping assembly includes four bearing plates 5, four first cylinders 51 and four guide rollers 52. The bearing plates 5 are slidably connected to the front and rear inner walls of the swing arm 4 in pairs, and the two bearing plates 5 located on the same inner wall of the swing arm 4 are symmetrically arranged. The four first cylinders 51 are all arranged on the swing arm 4 and correspond to the bearing plates 5 one by one. When the first cylinders 51 are running, they can drive the corresponding bearing plates 5 to move independently. The swing arm 4 is provided with a servo motor 421 disposed on the side wall of the frame 1. The servo motor 421 is capable of causing the swing arm 4 to swing with its hinge axis as a reference in a belt drive manner when the servo motor 421 is in operation.

[0034] Among them, refer to Figure 2 and Figure 5 The tensioning mechanism 3 includes a tensioning roller 31 and a tension spring 32. Two tensioning rollers 31 are provided and are respectively slidably connected to the left and right ends of the frame 1. The two tensioning rollers 31 can both abut the outer surface of the belt 21. The tension spring 32 is provided between the frame 1 and the tensioning roller 31 and can make the two tensioning rollers 31 have a tendency to approach each other.

[0035] When the moisture-proof gypsum board is turned over and conveyed, the moisture-proof gypsum board is first placed at the loading end on the left side of the belt 21, and then the swing arm 4 is swung to the right based on its own hinge axis through the cooperation of the driving member 42, until the swing roller 41, the transmission roller 22 at the upper left end and the guide roller 52 at the upper left end are in the same inclined plane. At this time, the belt 21 between the swing roller 41 and the transmission roller 22 at the upper left end is in a straight line state inclined downward from left to right, and this part of the belt 21 is in tangential contact with the guide roller 52 at the upper left end, and then, with the cooperation of the external driving device, the belt 21 is displaced around the four transmission rollers 22 and the moisture-proof gypsum board is conveyed to the right.

[0036] When the moisture-proof gypsum board is transferred between the four guide rollers 52, the airbag 6 will expand with the cooperation of the external air pump and abut against the end face of the moisture-proof gypsum board. At this time, the external driving device stops to stop the belt 21 from conveying the moisture-proof gypsum board. Then the first cylinder 51 runs to move each supporting plate 5 and the guide roller 52 toward the direction close to the moisture-proof gypsum board and apply pressure to the belt 21, thereby prompting part of the belt 21 on the left and right sides of the swing roller 41 to clamp and fix the moisture-proof gypsum board. In this process, the tensioning roller 31 can realize adaptive tensioning of the belt 21 under the action of the tension spring 32 to prevent the belt 21 from failing to hold force normally and affecting the conveying work.

[0037] Then, the driving member 42 cooperates with the swing arm 4 to swing leftward based on its own hinge axis until the moisture-proof gypsum board is turned over. The first cylinder 51 drives the supporting plates 5 and the guide rollers 52 to reset so that the belt 21 releases the clamping state of the moisture-proof gypsum board, so that the swing roller 41, the transmission roller 22 at the upper right end and the guide roller 52 at the upper right end are in the same inclined plane. At this time, the belt 21 between the swing roller 41 and the transmission roller 22 at the upper right end is in a straight line state inclined downward from right to left, and this part of the belt 21 is in tangential contact with the guide roller 52 at the upper right end. Then the external driving device is started again to make the belt 21 continue to transport the turned moisture-proof gypsum board to the right.

[0038] The moisture-proof gypsum board can be always positioned on the belt 21 for flipping, thereby reducing the possibility of the moisture-proof gypsum board being damaged by collision with other components due to inertia and gravity. When the moisture-proof gypsum board is skewed, the airbag 6 can provide flexible buffering support for the corners of the moisture-proof gypsum board, thereby reducing the probability of aggravated damage to the corners of the moisture-proof gypsum board.

[0039] Reference Figure 3 and Figure 4 The bottom end of the swing arm 4 is provided with a brake assembly 7, which is used to cooperate with the swing roller 41 to clamp and lock the belt 21 or unlock the belt 21. The brake assembly 7 includes a second cylinder 71 and a pressure plate 72. The second cylinder 71 is provided at the bottom end of the swing arm 4, and the pressure plate 72 is provided at the execution end of the second cylinder 71 and matches the swing roller 41, and the pressure plate 72 can abut against the inner surface of the belt 21.

[0040] When the moisture-proof gypsum board is transferred between the four guide rollers 52 and the external driving device stops to stop the belt 21 from conveying the moisture-proof gypsum board, the second cylinder 71 operates to make the pressure plate 72 close to the swing roller 41. At this time, the swing roller 41 and the pressure plate 72 cooperate to further clamp and lock the belt 21 to prevent the belt 21 from shifting in position during the turning process and affecting the clamping effect of the belt 21 on the moisture-proof gypsum board.

[0041] Reference Figure 4 and Figure 6A cleaning assembly 8 is provided on the longitudinal arm beam 401 at the bottom end of the swing arm 4, and is used to clean the residues remaining on the outer surface of the belt 21. The cleaning assembly 8 includes a scraper 81 and a residue suction hole 82. The scraper 81 is hinged to the longitudinal arm beam 401 at the bottom end of the swing arm 4 through a torsion spring, and the scraper 81 is located on the side away from the feeding end of the belt 21. The residue suction hole 82 is opened on the longitudinal arm beam 401 at the bottom end of the swing arm 4, and the residue suction hole 82 can be connected to an external dust collection device.

[0042] After the moisture-proof gypsum board has completed the turning over action, as the belt 21 continues to be transported, the scraper 81 can always abut against the outer surface of the belt 21 under the action of the torsion spring, so as to scrape off the residue that may be attached to the outer surface of the belt 21, and then the external vacuum equipment can operate to extract the residue scraped by the scraper 81 through the residue suction hole 82, thereby keeping the outer surface of the belt 21 clean and preventing the residue from adhering to the outer surface of the belt 21 and scratching the moisture-proof gypsum board transported subsequently.

[0043] In addition, refer to Figure 6 The scraper 81 is composed of a hollow knife sleeve 811 and a scraper 812 slidably connected to the inside of the hollow knife sleeve 811, and a spring 813 is provided between the hollow knife sleeve 811 and the scraper 812 to enable the scraper 812 to have a tendency to extend from the inside of the hollow knife sleeve 811.

[0044] The scraper 81 composed of the hollow knife sleeve 811 and the scraper 812 can have an adaptive telescopic function with the cooperation of the spring 813, so that the scraper 81 can participate in the work of turning over and conveying moisture-proof gypsum boards of different thicknesses.

[0045] The implementation principle of a conveying device for processing moisture-proof gypsum boards in the embodiment of the present application is as follows:

[0046] When the moisture-proof gypsum board is turned over and conveyed, the moisture-proof gypsum board is first placed at the loading end on the left side of the belt 21, and then the swing arm 4 is swung to the right based on its own hinge axis through the cooperation of the driving member 42, until the swing roller 41, the transmission roller 22 at the upper left end and the guide roller 52 at the upper left end are in the same inclined plane. At this time, the belt 21 between the swing roller 41 and the transmission roller 22 at the upper left end is in a straight line state inclined downward from left to right, and this part of the belt 21 is in tangential contact with the guide roller 52 at the upper left end, and then, with the cooperation of the external driving device, the belt 21 is displaced around the four transmission rollers 22 and the moisture-proof gypsum board is conveyed to the right.

[0047] When the moisture-proof gypsum board is transferred between the four guide rollers 52, the airbag 6 will expand with the cooperation of the external air pump and abut against the end face of the moisture-proof gypsum board. At this time, the external driving device stops to stop the belt 21 from conveying the moisture-proof gypsum board. Then the first cylinder 51 runs to move each supporting plate 5 and the guide roller 52 toward the direction close to the moisture-proof gypsum board and apply pressure to the belt 21, thereby prompting part of the belt 21 on the left and right sides of the swing roller 41 to clamp and fix the moisture-proof gypsum board. In this process, the tensioning roller 31 can realize adaptive tensioning of the belt 21 under the action of the tension spring 32 to prevent the belt 21 from failing to hold force normally and affecting the conveying work.

[0048] Then, the driving member 42 cooperates with the swing arm 4 to swing leftward based on its own hinge axis until the moisture-proof gypsum board is turned over. The first cylinder 51 drives the supporting plates 5 and the guide rollers 52 to reset so that the belt 21 releases the clamping state of the moisture-proof gypsum board, so that the swing roller 41, the transmission roller 22 at the upper right end and the guide roller 52 at the upper right end are in the same inclined plane. At this time, the belt 21 between the swing roller 41 and the transmission roller 22 at the upper right end is in a straight line state inclined downward from right to left, and this part of the belt 21 is in tangential contact with the guide roller 52 at the upper right end. Then the external driving device is started again to make the belt 21 continue to transport the turned moisture-proof gypsum board to the right.

[0049] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
