Description

TECHNICAL FIELD

[0001] The utility model relates to gypsum production technology, more specifically, relate to a kind of board conveying device and gypsum board production equipment. BACKGROUND

[0002] In the production process of gypsum board, the plaster is mixed into gypsum slurry by adding auxiliary materials and water, and the gypsum slurry is coated with face paper on both sides to form paper-faced gypsum board. After the paper-faced gypsum board is formed, it is sent into the drying machine (which has 12 layers) in order by the distribution bridge. After passing through the drying machine, the gypsum board is slowly discharged from the drying machine at a speed of 3.5 m / min. After the drying is completed, the gypsum board is discharged by the board placing system. The gypsum board is cut, edged, sealed, and stacked (in the process, it is called three controls, and in this document, it is defined as the downstream system). Then, it is packed into a whole rack of gypsum board and stored in the warehouse.

[0003] In the production process of gypsum board, the drying machine is allowed to stop in continuous production. However, stopping the drying machine in continuous production can cause uneven drying of the gypsum board, resulting in overburning, soft board, and other phenomena. The finished gypsum board is not qualified. If there is a problem in the three controls, the board placing system needs to be stopped and treated for three control faults. The main drive of the drying machine does not stop (stopping the main drive of the drying machine can cause the gypsum board to be overburned). The original equipment can only pause the drying machine for one minute. If the three control faults are not completely treated within one minute, the gypsum board at the board placing position will accumulate together, causing the accumulated gypsum board to be discarded and resulting in waste of products.

It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any way without conflict.

[0033] As Figures 1-5 shown, the utility model embodiment provides a kind of gypsum board production equipment and board conveying device 100, which can be used to transport the board after drying, wherein the board can be gypsum board.Gypsum board production equipment includes drying machine 1 and, be located at the board conveying device 100 of drying machine 1 board material output port, drying machine 1 is used to dry the board.

The predetermined time is generally about 10 minutes, so as to output the board dried in the drying machine; of course, it can also be other length of time, which can be set according to actual conditions.

[0036] The plate conveying device 100 of the utility model can control the plate placing system 2 to stop running and keep the dryer 1 running for a period of time when the downstream system fails, so that the plate output by the dryer 1 can be stored in the multiple pre-storage systems 3a, 3b and 3c, thereby preventing the plate in the dryer 1 from being dried unqualifiedly or preventing the plate in the dryer 1 from being directly conveyed to the plate placing system 2 and colliding and overlapping with the plate on the plate placing system 2, which can only be disposed of as waste, so that the utility model discloses a plate conveying device 100 improves the qualified rate of plate products and saves energy.

[0037] In the embodiment, the multiple pre-storage systems 3a, 3b and 3c include the first pre-storage system 3a, the second pre-storage system 3b and the third pre-storage system 3c arranged in sequence along the plate conveying direction.

[0038] As shown in Figure 3 , Figure 4 , along the height direction, each pre-storage system 3a, 3b and 3c includes multiple layers of storage sections 30. As shown in the drawings, each pre-storage system 3a, 3b and 3c includes 12 layers of storage sections 30, and adjacent layers of storage sections 30 have a certain interval and can store enough plate conveyed by the dryer 1.

[0039] The control device is further arranged to control the multiple pre-storage systems 3a, 3b and 3c to store the plate in the multiple layers of storage sections 30 in sequence from the last pre-storage system 3c to the first pre-storage system 3a when the downstream system is in the fault state.

[0040] As shown in Figure 3 , Figure 4 , each layer of storage section 30 includes a conveying roller 301, a motor 302 driving the conveying roller 301 to move and an inductive device 303 detecting the plate signal of the conveying roller 301.

[0041] The control device is arranged to control the motors of the storage sections 30 of the upstream pre-storage system and the storage sections 30 of the same level as the current storage section 30 to run when the downstream system is in a fault state and the sensing device 303 of the current storage section 30 does not detect the presence of the plate; the control device is arranged to control the motors 302 of the current storage section 30 to stop moving when the downstream system is in a fault state and the sensing device 303 of the current storage section 30 and the sensing device 303 of the storage section of the same level as the current storage section 30 of the downstream pre-storage system both detect the presence of the plate. Through the above arrangement, the multiple pre-storage systems 3a, 3b, 3c can arrange the storage plates as orderly as possible.

[0042] In an exemplary embodiment, each storage section 30 of each pre-storage system 3a, 3b, 3c includes multiple sensing devices, respectively located upstream and downstream of the conveying roller 302 of the storage section 30. When the upstream sensing device 303 of the storage section 30 detects the presence of the plate and the downstream sensing device 303 detects the absence of the plate, the control device controls the motor 302 of the storage section 30 to run at a first predetermined speed; when the upstream and downstream sensing devices 303 of the storage section 30 both detect the absence of the plate, the control device controls the motor 302 of the storage section 30 to run at a second predetermined speed; the second predetermined speed is less than the first predetermined speed.

[0043] In this embodiment, due to the normal working state, the plates will continuously pass through the pre-storage systems 3a, 3b, 3c, and in order to improve the conveying efficiency of the plates, the conveying speed of the pre-storage systems 3a, 3b, 3c is increased to reduce the reduction of the plate conveying speed caused by the additional pre-storage systems 3a, 3b, 3c.

[0044] As shown in Figure 3 , Figure 4 , the motors 302 of the adjacent storage sections 30 of the same pre-storage system 3a, 3b, 3c are staggered to facilitate installation.

[0045] As shown in Figure 3 , Figure 4 , the heights of the multiple pre-storage systems 3a, 3b, 3c gradually decrease from the first pre-storage system 3a towards the last pre-storage system 3c, and the spacing between the adjacent storage sections 30 gradually decreases, so that a certain distance is maintained between the adjacent storage sections 30 of the same pre-storage system 3a, 3b, 3c during the upstream movement for plate conveying, and the height is reduced during the downstream plate placing process to facilitate the smooth conveying of the plates to the lower plate placing system 2 for sequential plate placing.

[0046] In the embodiment, the induction device 303 is arranged upstream and downstream of each storage section 30, so that the speed of the conveying roller 301 can be increased when the plate passes through the storage section, thereby increasing the conveying speed of the plate; and the speed can be decreased when no plate passes through, thereby saving energy.

[0047] As shown in Figure 5 , the plate output system 2 includes a plurality of sections connected in sequence along the conveying direction of the plate, each section having a plurality of layers in the height direction, each layer being provided with a motor 20 and an induction device 303. The plate output port of each layer of the plate output system 2 is provided with a stop device 22 for stopping the output of the plate, the stop device 22 including a stop rod 221, a swing arm 222 mounted on one side of the stop rod 221, and a cylinder mechanism (not shown) for driving the swing arm 222 to move; the stop device 20 is connected to a control device, which is configured to control the cylinder mechanism to drive the swing arm 22 to move to stop the plate when a fault occurs and the induction device 303 senses that there is a plate, thereby preventing the plate from being conveyed to the downstream system.

[0048] As shown in Figures 6-8 , the induction device 303 includes a fixed base 3030, a rotating shaft 3031 arranged on the fixed base 3030, and a rotating shaft 3031 rotatably arranged on the fixed base 3030. The fixed base 3030 is arranged on the conveying roller 301 of each layer of the storage section 30 and stops on the conveying path of the gypsum board.

[0049] The induction device 303 further includes one or more baffles 3032 arranged on the rotating shaft 3031 and capable of driving the rotating shaft 3031 to rotate, the one or more baffles 3032 being capable of being flipped by the gypsum and driving the rotating shaft 3031 to rotate. The induction device 303 further includes an induction assembly including an induction mechanism 3033 arranged on the rotating shaft 3031 and a proximity induction switch 3034 cooperating with the induction mechanism 3033 to trigger an induction signal. The induction mechanism 3033 includes a mounting disc 3033-1 and an inductor 3033-2 adjustably mounted on the mounting disc 3033-1. The baffle 3032 of the embodiment is made of nylon, and the inductor 3033-2 is semicircular and can be adjusted in position on the mounting disc 3033-1 in the circumferential direction of the mounting disc 3033-1.

[0050] The inductor 3033-2 of the embodiment is designed to be semicircular and can be adjusted at any angle on the mounting disc 3033-1. In the embodiment, a plurality of mounting holes T are arranged in the circumferential direction of the mounting disc 3033-1, and the inductor 3033-2 is detachably mounted in the mounting hole T of the mounting disc 3033-1 by a bolt or the like connecting member.

[0051] When the plasterboard arrives, it contacts the baffle 3032, causing the baffle 3032 to tilt. This tilts the entire sensing mechanism 3033, causing the sensor 3033-2 to move closer to the proximity switch 3034, sending a signal to the DCS system. Therefore, even when the baffle 3032 is worn down by the plasterboard, the position of the sensor 3033-2 ensures that it can still accurately detect the signal. The semi-circular design of the sensor 3033-2 in this embodiment prevents the entire sensing assembly from rotating due to contact with the baffle 3032. Instead, it allows the sensor 3033-2 to be pressed against the proximity switch 3034 for sensing.

[0052] like Figure 9 , Figure 10 As shown, the sensing device 303 also includes a reset mechanism that drives the rotating shaft 3031 to reset. The reset mechanism includes a gear 3035 mounted on the rotating shaft 3031, a chain 3036 meshing with the gear 3035, and a counterweight 3036 connected to the chain 3036. When the rotating shaft 3031 rotates, causing the baffle 3032 to flatten, it drives the chain 3036 to move. The chain 3036 drives the gear 3035 to rotate, and the gear 3035 drives the counterweight 3036 to move. When the plasterboard passes by, the counterweight 3036 drives the gear 3035 to rotate, and the chain 3036 drives the rotating shaft 3031 to return to its original position.

[0053] In one embodiment, the control device is configured to, when in normal operation and when the sensing device 303 of any storage segment of the first pre-stored system senses a board, control all downstream pre-stored systems 3b / 3c and the motors 302 of the storage segment 30 located on the same layer as the storage segment 30 to move at a third predetermined speed, the third predetermined speed being greater than the first predetermined speed and the second predetermined speed.

[0054] In this embodiment, multiple sensing devices 303 are provided downstream of the multiple storage segments 30 of the end pre-storage system 3c. The control device is configured to control the plate feeding system 2 to operate when the downstream system of the dryer 1 is in normal state and when the downstream sensing device 303 senses that there is a plate, so as to transport the plate to the plate feeding system 2.
