Description

Technical Field

[0001] This utility model relates to the field of flame-retardant gypsum board production, and in particular to a flame-retardant gypsum board production device. Background Technology

[0002] Gypsum board is a common building material, widely used in the home decoration industry. Depending on different user needs, there are various types of gypsum board, such as waterproof gypsum board, flame-retardant gypsum board, and heat-insulating gypsum board. Our flame-retardant gypsum board has a layer of flame-retardant mesh added inside. When a fire occurs in the house, the flame-retardant mesh prevents the bottom of the gypsum board from burning due to its flame-retardant and support properties. In order to facilitate better laying of the flame-retardant mesh, we have designed a flame-retardant gypsum board production device. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a flame-retardant gypsum board production device, including a slurry feeding silo and a conveyor belt. The conveyor belt carries a bottom protective paper, which is folded on both sides by pressure rollers. The feeding port below the slurry feeding silo feeds the bottom protective paper, including a flame-retardant mesh feeding roll and limiting rollers. The flame-retardant mesh feeding roll is horizontally arranged above the conveyor belt. Two sets of limiting rollers are arranged below one side of the flame-retardant mesh feeding roll, with multiple limiting rollers arranged side by side in each set. The limiting rollers press down on the flame-retardant mesh and the bottom protective paper of the flame-retardant mesh feeding roll.

[0004] The conveyor belt is provided with guide wheels that are inclined outward on both sides. The bent paper surfaces on both sides of the bottom protective paper are attached to the guide wheels and form an angle greater than 90 degrees with the bottom protective paper.

[0005] The rotating shafts on both sides of the flame-retardant mesh feed roll are equipped with bearings, and the bearings on both sides are installed in matching limiting grooves with openings at the top. The limiting grooves are fixed to the bracket below.

[0006] Each set of the aforementioned limit wheels has 4.

[0007] A connecting plate is provided above the limiting wheel, and the limiting wheel is rotatably mounted on the first connecting plate. A second connecting plate is provided on the two connecting plates facing outwards. A fixing plate in the shape of a "[" is provided on the side of the second connecting plate away from the limiting wheel. The upper and lower horizontal plates of the fixing plate are vertically provided with through holes. The through holes can be inserted into the support column, and the bottom of the support column is fixed to the bracket. Threaded holes are provided on one side of the two horizontal plates of the fixing plate. The threaded holes are connected to the through holes. Bolts with threaded engagement are provided in the through holes, and the bolts are used to fix the support column.

[0008] The beneficial effects of this utility model are as follows:

[0009] This device uses limiting wheels on both sides to press the flame-retardant mesh, which is then transported via a conveyor belt. Due to the pressure from the mud in the middle and the limiting wheels on both sides, the flame-retardant mesh is integrated into the mud and will not stick to the underlying protective paper, thus providing better protection for both sides of the gypsum board. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Figure 1 This is a schematic diagram of the present invention.

[0012] Figure 2 This is a partially enlarged schematic diagram of the present invention. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0014] See Figure 1-2 .

[0015] The conveyor belt and the slurry feeding silo are conventional equipment in this field and are not innovative points in this case, so they will not be described in detail here.

[0016] This utility model discloses a flame-retardant gypsum board production device, including a slurry feeding silo 1 and a conveyor belt 2. A bottom facing paper 3 is conveyed on the conveyor belt. The bottom facing paper is folded on both sides by pressure rollers. A feeding port below the slurry feeding silo supplies the bottom facing paper, including a flame-retardant mesh feeding roll 4 and limiting wheels 5. The flame-retardant mesh feeding roll is horizontally positioned directly above the conveyor belt. Two sets of limiting wheels are arranged below one side of the flame-retardant mesh feeding roll, with multiple limiting wheels arranged side-by-side in each set. The limiting wheels press down on the flame-retardant mesh and the bottom facing paper of the flame-retardant mesh feeding roll. The flame-retardant mesh feeding roll itself is not powered; its power comes from two sources: one is the power of the limiting wheels pressing down on the flame-retardant mesh and the bottom facing paper as they pass through the conveyor belt; the other is the tensile force generated by the long-distance transport of the gypsum board before solidification, during which the flame-retardant mesh is constantly wrapped in the slurry. The reason for injecting grout before laying the flame-retardant mesh is that if the flame-retardant mesh is laid first, it will adhere to the protective paper. When the grout is injected first, the grout in the middle has a certain height, and the flame-retardant mesh on both sides adheres to the protective paper, which will generate a certain pressure, causing the flame-retardant mesh to fuse in the middle area of ​​the grout.

[0017] The conveyor belt is equipped with outwardly inclined guide rollers 6 on both sides. The bent paper surfaces 7 on both sides of the bottom protective paper adhere to the guide rollers 6, forming an angle greater than 90 degrees with the bottom protective paper. The guide rollers 6 cause the bottom protective paper to bend upward on both sides, which can prevent mud from flowing out.

[0018] The rotating shafts on both sides of the flame-retardant mesh feed roll are fitted with bearings 8. The bearings on both sides are installed in matching limiting grooves 9 with openings on the top. The limiting grooves are fixed to the bracket 10 below.

[0019] Each set of the aforementioned limit wheels has 4.

[0020] A first connecting plate 11 is provided above the limiting wheel, and the limiting wheel is rotatably mounted on the first connecting plate. A second connecting plate 12 is provided on the two connecting plates facing outwards. A fixing plate 13 in the shape of a "[" is provided on the side of the second connecting plate away from the limiting wheel. The upper and lower horizontal plates 131 of the fixing plate are vertically provided with through holes. The through holes can be inserted into the support column 14, and the bottom of the support column is fixed to the bracket 10. Threaded holes are provided on one side of the two horizontal plates of the fixing plate. The threaded holes are connected to the through holes, and bolts 15 with threaded engagement are provided in the through holes. The bolts press against the support column for fixation. By tightening the bolts, the limiting wheel is lifted, and then a flame-retardant mesh is placed in. The limiting wheel is then lowered to press down the flame-retardant mesh and the conveyor belt. Finally, the first connecting plate is fixed by tightening the bolts, thereby limiting the position of the limiting wheel.

[0021] Specific operations

[0022] The conveyor belt 2 transports the bottom protective paper 3. The bottom protective paper 3 is then transported through the slurry feeding bin 1, which injects slurry into the middle. The flame retardant mesh of the flame retardant mesh feeding roll 4 is pressed down by the limiting wheels 5 on both sides. The flame retardant mesh on both sides is attached to the bottom protective paper 3. There is slurry in the middle, so the middle of the flame retardant mesh will not be completely pressed to the bottom of the bottom protective paper 3. It will be mixed with the slurry and sent to the subsequent process for pressing and baking.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
