Description

Technical Field

[0001] This utility model relates to a hot pressing device, and more particularly to a hot pressing device for heat insulation plates. Background Technology

[0002] Heat insulation panels, commonly used in automotive interiors and other fields, are sheets formed by stacking and hot-pressing fabrics made of various polymer fibers. During the hot-pressing process, pressure rollers at a certain temperature press against the stacked fabrics, causing the fibers to shrink and tighten under pressure. Because the hot-pressing process is relatively short, when the sheet has a certain thickness, the fabric in the center cannot be heated due to the excessive thickness of the sheet, resulting in a looser center compared to the outer edges. This leads to insufficient strength in the sheet. On the other hand, extending the hot-pressing time may cause the outer edges of the sheet to overheat, deform, and bend, rendering the sheet unusable. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a heat insulation plate hot pressing device that can heat the plate evenly inside and out.

[0004] To achieve this objective, the structure adopted in this utility model is as follows: a heat insulation plate hot pressing device, including a frame, on which tension rollers, heating rollers, pressure rollers, transmission rollers and separation rollers are arranged. A ring-shaped hot pressing mesh is sleeved on each roller. The tension roller presses the hot pressing mesh. The surface of the hot pressing mesh is arranged with barbs. The hot pressing mesh is a mesh structure woven from metal wire.

[0005] Hydraulic cylinders are symmetrically arranged on both sides of the frame, and the piston rods of the hydraulic cylinders are connected to both ends of the tensioning roller through a gear set.

[0006] The tensioning roller is located above the separating roller, the heating roller is located above the pressure roller, the heating roller and the tensioning roller are at the same height, and the transmission roller is located in the center of the tensioning roller, the heating roller, the pressure roller and the separating roller.

[0007] The needles are arranged on the surface of the hot-pressed mesh, with a needle length of 0.5 to 3 cm and a distance of 5 to 20 cm between adjacent needles.

[0008] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. After the hot pressing mesh is heated by the heating roller, it is pressed on the layered fiber fabric, flattened and hot-pressed with a grid pattern under the action of heating. The grid pattern is harder than the surrounding fiber fabric, so that it plays a linear shaping and support role. At the same time, the needles on the surface of the hot pressing mesh penetrate into the center of the material when passing through the pressure roller, so that the center of the material forms a dense hot pressing point evenly, ensuring the tightness of the internal structure of the board. Attached Figure Description

[0009] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0010] Figure 1 This is the front view of this utility model;

[0011] Figure 2 This is a diagram of the hot-pressed mesh structure. Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0013] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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 an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 The heat-pressing device for the heat insulation board shown includes a frame 1. Parallel tension rollers 2, heating rollers 3, pressure rollers 4, transmission rollers 5, and separating rollers 6 are arranged on the frame 1. A ring-shaped heat-pressing mesh 7 is threaded between the rollers. Gear sets 8 are located at both ends of the tension rollers 2, and these gear sets 8 are connected to the frame 1 via sliding grooves 10. Two sets of hydraulic cylinders 9 are located at corresponding positions on the frame 1. The hydraulic cylinders 9 are connected to both ends of the tension rollers 2 via the gear sets 8. The hydraulic cylinders 9 control the position of both ends of the tension rollers 2 on the sliding grooves 10 through piston movement, thereby controlling the tension of the heat-pressing mesh 7. The heating rollers 3 heat the heat-pressing mesh 7, which is a mesh structure woven from metal wires. After passing through the heating rollers 3, it is uniformly heated. After passing through the pressure rollers 4 and contacting the polymer fiber fabric, a texture is imprinted on its surface, forming linear grooves that provide support.

[0016] The tensioning roller 2 is located above the separating roller 6, the heating roller 2 is located above the pressure roller 4, the heating roller 4 and the tensioning roller 2 are at the same height, the horizontal position of the separating roller 6 is 3 to 10 cm higher than the pressure roller 4, the transmission roller 5 is located in the center of the tensioning roller 2, the heating roller 3, the pressure roller 4 and the separating roller 6, and a motor is connected to one side of the transmission roller 5 to drive the rotation of the hot pressing mesh 7.

[0017] like Figure 2 As shown, the surface of the hot-pressed mesh 7 is arranged with barbs 11. The barbs 11 are metal needles with a length of 0.5 to 3 cm and a distance of 5 to 20 cm between adjacent barbs. Different lengths and arrangement densities of barbs 11 are selected according to the thickness and hardness of the hot-pressed material. When the barbs 11 penetrate the hot-pressed material, a contraction point is formed in the center of the hot-pressed material. The contraction points are evenly distributed in the center of the plate to form point support, which avoids the structure in the center of the plate being loose and the plate strength being insufficient.

[0018] Meanwhile, the presence of the needles 11 can keep the board and the hot press mesh 7 synchronized, and avoid insufficient tension of the hot press mesh 7, which would cause the hot stamping on the board surface to be messy and affect the quality of the board.

[0019] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
