Description

Technical Field

[0001] The utility model relates to the field of flame retardant board production equipment, in particular to a pre-pressing device for flame retardant board production. Background Art

[0002] Flame retardant panels are a type of building material with fireproof properties, commonly used in building structures such as walls, ceilings and floors. They can effectively slow the spread of fire, provide more escape time, and reduce property losses caused by fire. Flame retardant panels are usually made of flame-retardant materials, such as fiberglass, gypsum, silicate, etc., with high fire resistance, able to maintain structural integrity in a fire, and play a role in preventing the spread of fire. Flame retardant panel production pre-pressing refers to the process of pre-pressing the material when producing flame retardant panels. The main purpose of this process is to ensure the density and uniformity of the flame retardant panel to improve its structural stability and fire resistance. Through pre-pressing, the flame retardant panel can be formed more tightly, reduce internal voids, and increase the density of the material, thereby improving its compression resistance, bending resistance and other properties. Pre-pressing also helps to eliminate bubbles and loose parts in the material, improve the quality and durability of the flame retardant panel, and for this reason, a flame retardant panel production pre-pressing device is usually used in the production process of the flame retardant panel.

[0003] At present, China utility model patent CN 215094332 U announced a pre-pressing device for the production of flame retardant panels. The pre-pressing device for the production of flame retardant panels is provided with a hydraulic push rod. The hydraulic push rod is started, and the hydraulic push rod drives the support plate to move downward to work. Then the pre-pressing head can pre-press the workpiece on the top of the working chamber downward. By providing an electric push rod, when it is necessary to clamp different pre-pressed workpieces, the electric push rod can be started to extend, and the connecting plate can be driven to move away to the opposite side, so that the pre-pressed workpiece with a slightly larger size can be placed, and then the electric push rod is started to a retracted state, so that the connecting plate moves to the opposite side, and the pre-pressed workpiece can be clamped by the clamping plate. By providing a telescopic rod and a spring, the stability of the clamping plate can be increased when clamping, so that the clamping effect is more stable. However, the device clamps and pre-presses the flame retardant plate. The flame retardant plate is made of mixed extrusion of flame retardant materials and additives. It is clamped and extruded during the pre-pressing process. Before the flame retardant plate is formed, the flame retardant material will diffuse to the two sides without the clamping plate, which will cause deformation of the flame retardant plate and waste of flame retardant material. Therefore, there is an urgent need for a pre-pressing device for producing flame retardant panels. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings:

[0023] like Figure 1-Figure 4As shown, a pre-pressing device for the production of flame-retardant panels comprises: a workbench 1 and a connecting frame 2 fixedly connected to the middle end of the top surface of the workbench 1, connecting grooves are respectively provided at both ends of both sides of the workbench 1, and a clamping block 3 is provided in the connecting groove, a frame plate 4 is provided at the middle end of the top surface of the workbench 1, and the four corners of the frame plate 4 are fitted with the clamping block 3, a hydraulic push rod 5 is provided at the middle end of the bottom surface of the connecting frame 2, and a pressing plate 6 is provided at the output end of the hydraulic push rod 5, wherein the connecting grooves are respectively opened at both ends of both sides of the workbench 1, that is, the four corners of the workbench 1, the clamping block 3 is clamped on the four corners of the workbench 1 through the connecting grooves, and the clamping block 3 is fixed and limited to the workbench 1 by limiting bolts to prevent the clamping block 3 from falling off from the connecting grooves. The limiting bolt can be separated from the block 3 and the workbench 1. When the limiting bolt, the block 3 and the workbench 1 are separated, the block 3 can be taken out from the workbench 1. The top surface of the block 3 has two protruding surfaces, and the two protruding surfaces are rectangular. The two protruding surfaces are perpendicular to each other and form a cavity. The frame plate 4 is placed on the top surface of the workbench 1, and its four corners are all located in the cavity formed by the two protruding surfaces of the block 3 and fit with the protruding surfaces. Then, the frame plate 4 is fixed to the top surface of the workbench 1 by the block 3, and the frame plate 4 is limited to prevent it from moving on the surface of the workbench 1 during the pressing process. The hydraulic push rod 5 is fixedly installed at the middle end of the bottom surface of the connecting frame 2, and its output end is fixedly connected with The pressing plate 6 is provided, and the size of the pressing plate 6 is consistent with the size of the cavity formed by the inner wall of the frame plate 4. The cavity formed by the inner wall of the frame plate 4 is used to place a mixture of flame retardant materials and additives for producing flame retardant panels. The output end of the hydraulic push rod 5 pushes the pressing plate 6 into the cavity of the frame plate 4, thereby pressing and molding the mixture of the flame retardant material and the additive to form a flame retardant panel. The mixture of the flame retardant material and the additive is restricted by the frame plate to prevent the mixture of the flame retardant material and the additive from being squeezed during the pressing process and diffusing to the surrounding area, causing the flame retardant panel to deform and reduce the quality of the flame retardant panel while reducing the waste of raw materials. Among them, the outer wall around the pressing plate 6, the bottom surface of the pressing plate 6, the top surface of the workbench 1 and the frame The inner wall of the plate 4 is sprayed with an anti-sticking lubricant.

The cavity formed by the inner wall of the frame plate 4 is used to place a mixture of flame retardant materials and additives for producing flame retardant boards. The output end of the hydraulic push rod 5 pushes the pressing plate 6 into the cavity of the frame plate 4, thereby pressing and molding the mixture of flame retardant materials and additives to form a flame retardant board, thereby limiting the mixture of flame retardant materials and additives, and preventing the mixture of flame retardant materials and additives from being squeezed during the pressing process and diffusing to the surrounding area, causing the flame retardant board to deform, reduce the quality of the flame retardant board, and reduce the waste of raw materials.
