Abstract
Description
Technical Field
[0001] The utility model relates to a fabricating device, in particular to a fabric distribution system for producing polyurethane sandwich panels, which is applied to the field of heat insulation board production. Background Art
[0002] In some buildings that require heat insulation, heat insulation boards generally need to be installed for heat insulation. The heat insulation boards are connected to the wall surface by connectors and completely cover the wall surface, which can effectively block the heat transfer between the internal and external spaces. A fabricating device will be used when producing polyurethane heat insulation boards.
[0003] The production process of a continuous polyurethane heat insulation board production line is a way to produce polyurethane heat insulation boards. Its principle is that after the upper and lower coils are formed (without disconnection), polyurethane liquid is evenly sprayed on the lower formed coil by a polyurethane foaming machine gun head and then enters the mold at a uniform speed for curing.
[0004] However, the existing fabricating device has the phenomenon of uneven fabric spraying during use, which leads to uneven heat insulation boards produced, poor strength, and even serious lack of foam in the heat insulation boards, thus reducing the quality of heat insulation board production. Summary of the Utility Model
[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that the existing fabricating device has the phenomenon of uneven fabric spraying during use, which leads to uneven heat insulation boards produced, poor strength, and even serious lack of foam in the heat insulation boards, thus reducing the quality of heat insulation board production.
[0006] To solve the above problems, the present utility model provides a fabric feeding system for the production of polyurethane sandwich panels, which includes an upper template and a lower template. A fixed end die is provided between the upper template and the lower template. A push rod is fixedly connected to the right end of the fixed end die. A fabric cart is provided at the upper end of the lower template. A camera is fixedly connected to the upper end of the fabric cart. A fixed table is provided on the left side of the lower template. Two cylinders are fixedly connected to the upper end of the fixed table. A support plate is fixedly connected to the upper ends of the two cylinders. A guide wheel is fixedly connected to the upper end of the support plate. An upper fixing plate is provided above the upper template. A plurality of guiding components are fixedly connected to the lower end of the fixing plate. Each guiding component includes two mounting plates. The upper ends of the mounting plates are fixedly connected to the lower end of the fixing plate. Two rotating rods are rotatably connected between the two mounting plates. A guiding roller is fixedly sleeved on the outer circle of each rotating rod. A mounting rod is provided at the front end of one of the guiding components. The rear end of the mounting rod movably penetrates through the front mounting plate and is fixedly connected to one of the rotating rods. A positioning plate and a fixed end point are also fixedly connected to the lower end of the fixing plate. A motor is fixedly connected to the front end of the positioning plate. A pulley group is sleeved on the outer circles of the motor and the mounting rod. The fixed end point is located between the two mounting plates of the rightmost guiding component. A drag chain tube is fixedly connected to the inner wall of the fixed end point. One end of the drag chain tube away from the fixed end point sequentially movably penetrates through a plurality of guiding components and the guide wheel and is fixedly connected to the fabric cart. A material feeding port is opened at the upper end of the fixing plate.
[0007] In the above-mentioned fabric feeding device for the continuous production line of polyurethane heat insulation panels, the polyurethane foam gun head cart placed in the mold cavity can be evenly moved at a constant speed without moving the upper and lower panels. The gun head evenly sprays the polyurethane liquid on the lower template, so that the produced heat insulation panels are uniform and have high strength, improving the production quality.
[0008] As a further improvement of the present application, the guide wheel includes a fan-shaped outer shell. A plurality of rollers are rotatably connected to the inner wall of the fan-shaped outer shell. The plurality of rollers are distributed in a circular array around the central axis of the fan-shaped outer shell.
[0009] As a further improvement of the present application, the outer surfaces of the guiding roller and the rollers are both in contact with the outer surface of the drag chain tube. The two ends of the fixed end die are respectively in contact with the upper template and the lower template.
[0010] As a further improvement of the present application, the right ends of the two mounting plates on the rightmost side are jointly fixedly connected with a U-shaped drag chain groove, and the drag chain groove is located below the drag chain tube.
[0011] As another improvement of the present application, the fabric cart includes a trailer and a spray pipe fixedly connected to the right end of the trailer. A plurality of nozzles are fixedly connected to the right end of the spray pipe.
[0012] As another improvement of the present application, a slide plate is fixedly connected to the lower end of the trailer. The lower end of the slide plate is in sliding contact with the upper end of the lower template. A speed sensor is fixedly connected to the front end of the trailer. The speed sensor, the camera, the cylinders and the motor are all in signal connection with an external controller.
[0013] In summary, in the actual application process, a drag chain pipe with a material pipe and an air pipe inside is connected to the cloth truck. The motor is started to drive a rotating rod to rotate, so that the guide roller rotates, driving the drag chain pipe to move left and right, thereby driving the cloth truck to move. At the same time, the feeding system is started to convey the spraying material into the cloth truck and spray it between the upper template and the lower template. When the cloth truck is used as a reference object, it is equivalent to the upper template and the lower template moving at a uniform speed in opposite directions at the same time. The feeding time of the cloth truck is adjusted according to the heat insulation boards of different sizes. When the feeding time is completed, the cloth truck just walks from one end of the lower template to the other end, so as to evenly spray the polyurethane liquid on the lower template, making the produced heat insulation boards uniform and with high strength, and can simultaneously produce polyurethane sandwich panels with fire protection grade B1 or B2 and conventional ones, improving the production quality.

A material feeding port is opened at the upper end of the fixed plate 9. The right ends of the two rightmost mounting plates 10 are fixedly connected together with a U-shaped drag chain groove 19. The drag chain groove 19 is located below the drag chain tube 18. After the upper template 1 and the lower template 2 are installed in the mold, by pushing the push rod 4, the volume between the upper template 1 and the lower template 2 can be adjusted, so as to facilitate the production of heat insulation plates of different sizes.
[0026] Figure 3 shows: The guide wheel 8 includes a sector-shaped outer shell. A plurality of rollers are rotatably connected to the inner wall of the sector-shaped outer shell.
