Description

Technical Field

[0001] This utility model relates to the field of composite insulation board processing technology, specifically a molding die for processing polyurethane composite insulation boards. Background Technology

[0002] Polyurethane insulation board is a new type of fireproof and heat-insulating board with an inorganic fireproof layer pressed onto its surface. It integrates fire prevention and heat insulation and has become an indispensable new type of system insulation product in the current building energy conservation market. It has the characteristics of easy pasting, good heat insulation performance, high flame retardant performance, stable quality, fluorine-free and environmentally friendly, and simple and easy construction. It is widely used in exterior wall insulation decoration, high-end residential buildings, and public building exterior wall insulation.

[0003] Chinese patent CN217144899U discloses a pressing mold for processing polyurethane composite insulation boards. By setting the cutting structure and the supporting mold as polyprismatic prisms with the same number of edges, during pressing, the supporting platforms on different sides of the supporting mold can be selected according to the size of the insulation board. Cutting blocks set on different sides of the cutting block are used for cutting. The set adjustment mechanism can rotate the cutting block and the supporting mold simultaneously and ensure that the angle of rotation of the cutting block and the supporting mold is the same, which makes it convenient for the staff to adjust the cutting block and the supporting mold.

[0004] While the above solutions utilize a support mold to hold the insulation board in place during the lamination process, the single-sided lamination method results in poor bonding of the composite laminate, thus affecting the final quality of the polyurethane composite insulation board. Therefore, we provide a lamination mold for processing polyurethane composite insulation boards to solve these problems. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a molding die for processing polyurethane composite insulation boards.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a molding die for processing polyurethane composite insulation boards, comprising:

[0009] A film pressing box is provided with inlet and outlet ports on both sides. Two heaters are installed on the film pressing box. The heating ends of the two heaters are rotatably connected to a rotating shaft. A squeezing roller is sleeved on the rotating shaft. A heat-conducting block is fixedly connected to the squeezing roller, and the end of the heat-conducting block away from the squeezing roller is fixedly connected to the rotating shaft.

[0010] The drive assembly, located on the pressing box, is used to control the two rotating shafts to rotate in opposite directions.

[0011] Two exhaust boxes are symmetrically arranged inside the film pressing box. Each exhaust box has an air inlet, and the film pressing box is equipped with an adjustment component for adjusting the position of the exhaust boxes.

[0012] The exhaust assembly, located on the pressure film box, is used to simultaneously exhaust air from the two exhaust boxes.

[0013] Furthermore, the drive assembly includes a motor mounted on the pressing box, the output shaft of the motor being connected to any one of the rotating shafts via a belt and a pulley, and transmission gears being fixedly connected to both rotating shafts, with the two transmission gears meshing with each other.

[0014] Furthermore, the adjustment assembly includes a fixed plate fixedly connected inside the pressing box, an adjustment screw threadedly connected to the fixed plate, a linkage plate rotatably connected to one end of the adjustment screw, and one end of the linkage plate fixedly connected to the exhaust box.

[0015] Furthermore, a guide rod is slidably connected to the linkage plate, and one end of the guide rod is fixedly connected to the linkage plate.

[0016] Furthermore, the exhaust assembly includes a storage box installed on the film pressing box, an exhaust fan is installed on one side of the storage box, a filter screen is installed inside the storage box, and two connecting pipes are fixedly connected to the other side of the storage box, and the two connecting pipes are respectively fixedly connected to two exhaust boxes.

[0017] Furthermore, a base is fixedly connected to the bottom surface of the pressing box.

[0018] (iii) Beneficial effects:

[0019] Compared with existing technologies, the pressing mold for processing polyurethane composite insulation boards has the following advantages:

[0020] I. This utility model overcomes the problem of poor adhesion caused by traditional single-sided pressing by setting up a double-sided synchronous pressing structure and using two heated extrusion rollers rotating in opposite directions to simultaneously heat and extrude the substrate and composite layer of the insulation board. The heat-conducting block evenly transfers the heat of the rotating shaft to the extrusion rollers, ensuring stable temperature during the pressing process and significantly improving the bonding strength between the composite layer and the substrate, thereby improving the overall quality of the polyurethane composite insulation board.

[0021] II. This utility model uses a rotating adjusting screw to move the exhaust box, adapting to the film pressing requirements of insulation boards of different thicknesses and enhancing its applicability. The exhaust assembly uses a fan to draw the irritating gases generated during the film pressing process into a storage tank, where they are filtered and centrally treated. This ensures a safe and environmentally friendly working environment while preventing residual gases from interfering with the film pressing quality. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-2 As shown, this utility model provides a technical solution: a molding die for processing polyurethane composite insulation board, including a molding box 1, a driving assembly, two exhaust boxes 11 and an exhaust assembly.

[0027] The pressing box 1 has inlet and outlet ports 2 on both sides. The base plate and composite plate of the insulation board enter the pressing box 1 through the inlet and outlet ports 2 for pressing and composite, and then move out of the pressing box 1 through the other inlet and outlet port 2. Two heaters 7 are installed on the pressing box 1. The heating ends of the two heaters 7 are rotatably connected to the rotating shaft 3. The heat generated by the heating ends of the heaters 7 is transferred to the rotating shaft 3, so that the middle of the rotating shaft 3 has a certain amount of heat. The rotating shaft 3 is fitted with a pressing roller 6. A heat-conducting block 10 is fixedly connected to the pressing roller 6, and the end of the heat-conducting block 10 away from the pressing roller 6 is fixedly connected to the rotating shaft 3. The heat is transferred to the pressing roller 6 through the heat-conducting block 10, so that the pressing roller 6 has a certain temperature when pressing the insulation board, which effectively ensures the stability of the composite plate on the base plate. The bottom surface of the pressing box 1 is fixedly connected to the base 8.

[0028] The drive assembly is mounted on the film pressing box 1 and is used to control the two rotating shafts 3 to rotate in opposite directions. The drive assembly includes a motor 5 mounted on the film pressing box 1. The output shaft of the motor 5 is connected to either of the rotating shafts 3 via a belt and a pulley. Both rotating shafts 3 are fixedly connected with transmission gears 4, and the two transmission gears 4 mesh with each other.

[0029] The output shaft of motor 5 drives one of the rotating shafts 3 to rotate, and under the action of two transmission gears 4, the two rotating shafts 3 rotate in opposite directions, thereby pressing the insulation board by squeezing to ensure the pressing quality of the insulation board.

[0030] Two exhaust boxes 11 are symmetrically arranged inside the film pressing box 1. An air inlet 12 is provided on the exhaust box 11. An adjustment component 9 for adjusting the position of the exhaust box 11 is provided inside the film pressing box 1.

[0031] The adjusting assembly 9 includes a fixed plate 92 fixedly connected to the pressing box 1. An adjusting screw 93 is threadedly connected to the fixed plate 92. One end of the adjusting screw 93 is rotatably connected to a linkage plate 91, and one end of the linkage plate 91 is fixedly connected to the exhaust box 11. A guide rod 94 is slidably connected to the linkage plate 91, and one end of the guide rod 94 is fixedly connected to the linkage plate 91.

[0032] By rotating the adjusting screw 93, the adjusting screw 93 moves on the fixed plate 92, and under the guidance of the guide rod 94, the adjusting screw 93 drives the exhaust box 11 to move through the linkage plate 91, thereby adjusting the distance between the exhaust box 11 and the insulation plate.

[0033] The exhaust assembly is installed on the film pressing box 1 and is used to simultaneously exhaust the two exhaust boxes 11. The exhaust assembly includes a storage box 13 installed on the film pressing box 1. An exhaust fan 14 is installed on one side of the storage box 13. A filter screen 15 is installed inside the storage box 13. Two connecting pipes 16 are fixedly connected to the other side of the storage box 13, and the two connecting pipes 16 are respectively fixedly connected to the two exhaust boxes 11.

[0034] Because a heated film pressing method is used, a certain amount of irritating gas will be generated during the film pressing process. The gas in the film pressing box 1 can be transported to the storage box 13 through the air inlet 12, the exhaust box 11 and the connecting pipe 16 by the negative pressure generated after the exhaust fan 14 is started.
