Description

Technical Field

[0001] A double-layer gypsum board distributor with an anti-fall structure belongs to the technical field of material conveying equipment. Background Technology

[0002] With the acceleration of industrialized construction and the promotion of green and environmentally friendly building materials, gypsum board, due to its excellent properties such as lightweight, fire resistance, sound insulation, and ease of processing, is increasingly widely used in building decoration, partition walls, and ceilings. In a gypsum board production line, the distributor is a key conveying device connecting the forming section and the dryer. Its core function is to directionally and smoothly convey the formed wet gypsum board blanks layer by layer to the dryer for curing and drying. The feeding efficiency of the drying process directly affects the capacity of the entire production line. In existing gypsum board production lines, the distributor is usually a single-layer structure, receiving and conveying only one layer of wet gypsum board into the dryer at a time. As production line speeds increase, the single-layer distributor is gradually becoming a bottleneck in capacity. Therefore, there is an urgent need to develop a new type of distribution equipment that can achieve efficient double-layer conveying of gypsum board to the dryer without significantly increasing the floor space and cost, so as to break through the limitations of existing technology. However, how to achieve efficient, synchronous and stable double-layer feeding in a limited space has become a key technical problem restricting the upgrading of high-speed gypsum board production lines. By lifting and lowering each layer of conveying through the lifting mechanism, while improving efficiency, stability and safety issues also need to be considered. Utility Model Content

Detailed Implementation

[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0023] Reference Figure 1 The double-layer gypsum board distributor with anti-fall structure includes a frame 1, a support platform, a lower conveyor belt, an upper conveyor belt, a conveyor belt drive mechanism, a lifting mechanism, a counterweight device, and anti-fall structures. The upper and lower conveyor belts are vertically spaced apart. One end of the upper and lower conveyor belts is rotatably connected to the frame 1, and the other end is suspended on the lower side of the support platform by the lifting mechanism. The lifting mechanism is connected to the counterweight device. The conveyor belt drive mechanism is set on the frame 1 and connects the upper and lower conveyor belts. Multiple anti-fall structures are set on one side of the support platform. When the upper and lower conveyor belts are lifted, the anti-fall structures extend to the lower side of the upper and lower conveyor belts.

[0024] Specifically, the upper and lower conveyor belts have the same structure, are vertically parallel, and the upper conveyor belt is positioned above the lower conveyor belt. One end of each conveyor belt is rotatably connected to the frame 1 via hinge 19, and the other end passes under the bridge-type support platform, with the conveying height adjusted via a lifting mechanism. The frame 1 consists of two pillars and crossbars, with three layers of crossbars. The upper conveyor belt is positioned on the top layer, and the lower conveyor belt is positioned in the middle layer.

[0025] The upper conveyor belt includes an upper frame 2 and multiple belts 4, and the lower conveyor belt includes a lower frame 3 and belts 4. The structure is described in detail below using the upper conveyor belt as an example. One end of the rectangular upper frame 2 is rotatably connected to the uppermost crossbar via a hinge 19. The upper conveyor belt of this invention is divided into two ends. Each section of the conveyor belt consists of multiple belts 4 arranged parallel to each other on the upper frame 2, and each section of the conveyor belt is connected to a conveyor belt drive mechanism.

[0026] The conveyor belt drive mechanism includes a drive wheel 5, a driven wheel 6, a connecting roller 7, a bearing 8, and a drive motor 9. The two ends of the belt 4 are respectively mounted on the upper frame 2 via the drive wheel 5 and the driven wheel 6. The upper frame 2 has four short sides along the transport direction, and a conveyor belt is formed between two short sides. The short sides are located on the upper side of the two long sides and are higher than the long sides. The drive wheel 5 and the driven wheel 6 are located on the side of the short sides. After the belt 4 passes around the drive wheel 5 and the driven wheel 6, it returns from the lower side of the two short sides.

[0027] Multiple connecting rollers 7 are provided between the driving wheel 5 and the driven wheel 6. The direction of the connecting rollers 7 is perpendicular to the direction of the belt 4. The two ends of the connecting rollers 7 are connected to bearings 8 set on the upper frame 2. Each section of the conveyor belt is equipped with a drive motor 9, which is set on the long side of the upper frame 2 and connected to the driving wheel 5. The drive motor 9 drives the driving wheel 5 to rotate, thereby driving the belt 4 to rotate on the connecting rollers 7.

[0028] The upper conveyor belt is also equipped with a detection sensor 24. The two long sides of the upper frame 2 are provided with crossbeams for installing the detection sensor 24, so that the detection sensor 24 is set on the upper side of the upper frame 2, and can detect the gypsum board during the transportation of the gypsum board.

[0029] The support platform of this utility model includes columns 10 and platforms 11 set on both sides of the upper and lower conveyor belts. The platforms 11 are horizontally set between the two columns 10 and are erected on the upper end of the columns 10, with an installation space provided with the columns 10. The support platform is composed of a bridge-type combination of two platforms 11 and columns 10. Two lifting mechanisms are respectively set on the two platforms 11. The platforms 11 are surrounded by guardrails 26. A straight ladder 27 is provided on one side of the columns 10. When workers climb up to the platforms 11 by the straight ladder 27, the guardrails 26 can play a protective role.

[0030] Reference Figure 2 The lifting mechanism includes a lifting motor 13, a chain 14, a rotating shaft 15, and a sprocket assembly. Two lifting motors 13 are respectively positioned in the middle of the two platforms 11, connected to the two rotating shafts 15 via a shaft coupling. The rotating shafts 15 are positioned perpendicular to the transport direction, extending towards the upper sides of the two columns 10. A protective cover 25 is provided outside the shaft coupling for dust protection. A first sprocket 16 is located at the end of the platform 11, a third sprocket 18 is located in the installation space between the column 10 and the platform 11, and a second sprocket 17 is located on the side of the platform 11. The three sprockets form a triangular sprocket assembly. The column 10 is hollow inside. A circular through hole is provided on the upper surface of the column 10 corresponding to the lower side of the third sprocket 18. The chain 14 is mounted on the sprocket assembly, with one end connected through the through hole to a counterweight device located in the hollow cavity inside the column 10, and the other end connected to the lifting cantilever 20 mounted on the upper and lower conveyor belts.

[0031] The configuration device of this utility model is a counterweight 12. The two sides of the internal cavity of the column 10 are provided with slide rails, and the two sides of the counterweight 12 are provided with sliders. The sliders are set on the slide rails. The lifting motor 13 drives the rotating shaft 15 to rotate, thereby driving the first sprocket 16 to rotate, so that the chain 14 can rise and fall at the same time between the sprocket groups. The counterweight 12 rises and falls through the slide rails and sliders.

[0032] Lifting cantilever arms 20 are provided on both sides of the long side of the upper frame 2 and the lower frame 3. The lifting cantilever arms 20 are located between two parallel columns 10, and the positions of the upper and lower lifting cantilever arms 20 are staggered. The lifting cantilever arm 20 consists of a vertical mounting plate, a support frame for the vertical mounting plate, and a connecting column for the connecting chain 14. The mounting plate is fixed to the long side of the upper frame 2 by bolts. The support frame is perpendicular to the long side and extends out one end. The connecting column is located on one side of the support frame, and the chain 14 is fixedly connected to the connecting column.

[0033] Reference Figure 3The anti-fall structures are vertically spaced on the side of the column 10. This utility model has three anti-fall structures, which are set on the side away from the lifting cantilever 20. The upper and lower conveyor belts are both set with the highest lifting position and the lowest falling position. The height of the uppermost anti-fall structure is higher than the height of the lowest position of the upper conveyor belt, and the height of the lowermost anti-fall structure is higher than the height of the lowest position of the lower conveyor belt. That is, the height of the anti-fall structure is flush with the middle of the side of the upper frame 2 and the lower frame 3. The uppermost and lowermost anti-fall structures prevent the upper and lower conveyor belts from being damaged due to sudden descent caused by a malfunction. The middle anti-fall structure is used for routine maintenance, and its height is suitable for the height of maintenance personnel, making maintenance convenient.

[0034] The anti-fall structure includes a guide sleeve 21, a support plate 22, and a support rod 23. The support plate 22 includes a rectangular base plate and two side plates vertically arranged on the base plate. The two side plates are arranged parallel to each other at intervals. The base plate is fixed to the side of the column 10 by bolts. A guide sleeve 21 is fixed between the two side plates. The guide sleeve 21 is arranged parallel to the base plate. The support rod 23 is slidably arranged in the guide sleeve 21.

[0035] The support rod 23 is cylindrical at one end and flattened cuboid at the other. The cuboid is positioned at the center of the cylinder and parallel to its axis. The end of the cuboid is bent outward to form a handle, facilitating the operator's pushing and pulling of the support rod 23. The cuboid end of the support rod 23 has a positioning hole 31, and the upper side of the guide sleeve 21 has a groove containing a positioning post 30. When the upper and lower conveyor belts are lifted, the support rod 23 extends towards the conveyor belts until the positioning post 30 falls into the positioning hole 31. At this point, the support rod 23 extends under the upper and lower conveyor belts, preventing direct impact damage when the conveyor belts suddenly fall. A positioning sensor 29 is suspended corresponding to the position of the positioning post 30 to check whether the positioning post 30 has fallen into the positioning hole 31. If not, the control system will prompt the operator to push the support rod 23 under the upper and lower conveyor belts.

[0036] The cylindrical support rod 23 has bolt holes for fixing, and the guide sleeve 21 has through holes for fixing at both ends. When the support rod 23 does not need to be pushed out, the bolts pass through the through holes on the side away from the upper and lower conveyor belts and connect with the bolt holes to fix the support rod 23 in the position where it is not pushed out of the guide sleeve 21. When the support rod 23 is pushed out, the positioning sensor 29 detects that the positioning pin 30 falls into the positioning hole 31. At this time, the bolt holes on the support rod 23 coincide with the through holes on the guide sleeve 21 near the upper and lower conveyor belts, and are fixed with bolts to fix the support rod 23 in the position where it is pushed out of the guide sleeve 21.

[0037] Work process: Refer to Figure 4The wet gypsum board enters the present invention via the preceding conveying equipment and is fed into the dryer 28 for drying via the upper and lower conveyor belts. During the conveying process, the position of the gypsum board and the status of the equipment are detected by the detection sensor 24 and fed back to the control system, which automatically triggers lifting, lowering or conveying actions. Thus, the lifting mechanism pulls up or lowers one end of the upper and lower conveyor plates, so that two layers of gypsum board can be fed into the dryer 28 at the same time.

[0038] For example, if 10 layers of gypsum board need to be fed into the dryer 28, this utility model can decompose this task into two parallel 5-layer sub-tasks through spatial vertical integration. That is, the upper and lower conveyor belts are each responsible for conveying 5 layers to the dryer 28, which shortens the conveying time and improves the conveying efficiency.

[0039] After the upper and lower conveyor belts are lifted, the fixing bolts are pulled out, and the support rod 23 is pushed towards the conveyor belt until the positioning post 30 falls into the positioning hole 31. Then, the bolts are used to fix it. At this time, the upper and lower conveyor belts are supported by support rods 23 on both sides, which can prevent the conveyor belt from suddenly falling to the bottom layer due to failure and causing certain damage to the conveyor belt.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
