Description

Technical Field

[0001] This utility model relates to the field of polyurethane board production technology, and in particular to a polyurethane embossing device. Background Technology

[0002] Polyurethane board is a high-performance thermal insulation material with excellent thermal insulation, moisture and water resistance, and fire retardant properties. Polyurethane board embossing is a special process that creates textures or patterns on the surface of polyurethane boards. It is widely used in construction, home furnishing, industry and other fields. In the existing technology, the polyurethane material is heated by an embossing roller and then extruded to form the desired texture or pattern. However, if the cooling rate is too slow after embossing, the board will not set properly, resulting in deformation, bending, twisting or uneven thickness of the embossed polyurethane board. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing technology that the slow cooling rate after embossing leads to poor shaping of the board, resulting in deformation, bending, twisting or uneven thickness of the embossed polyurethane board, and to propose a polyurethane embossing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a polyurethane embossing device, including a support platform, a support frame fixedly connected to the upper end of the support platform, a movable block slidably connected to the support frame, an electric telescopic rod fixedly connected to the upper end of the movable block, the telescopic end of the electric telescopic rod passing through the movable block and fixedly connected to a mounting frame, an embossing roller rotatably connected to the mounting frame, a pump fixedly connected to the upper end of the movable block, a first connecting pipe connected to the outlet end of the pump, a second connecting pipe slidably inserted into one end of the first connecting pipe, the second connecting pipe connected to the mounting frame through a fixing plate, a horizontal pipe connected to one end of the second connecting pipe, and an air outlet pipe connected to the bottom end of the horizontal pipe.

[0006] Preferably, the upper end of the support platform is connected to a limiting frame.

[0007] Preferably, the air outlet pipes are provided in a plurality of them and are distributed at equal intervals along the length of the horizontal pipe, and one end of each air outlet pipe is inclined downward.

[0008] Preferably, the support platform has an air duct, and the upper end of the air duct has a plurality of heat dissipation holes, all of which are located within the limiting frame.

[0009] Preferably, the fixed plate is connected to a buffer mechanism for reducing the intensity of gas impact. The buffer mechanism includes an open box, which is fixedly connected to the fixed plate. The opening of the open box is located below the gas outlet pipe. A strip-shaped hole is opened at the bottom of the open box, and a fixing net is fixedly connected to the strip-shaped hole.

[0010] Preferably, the bottom of one side of the open box has a plurality of air holes at equal intervals along its length.

[0011] The polyurethane embossing device proposed in this utility model has the following advantages:

[0012] The moving block causes the embossing roller to roll and emboss the polyurethane board. At the same time, the pump is powered on and starts. After the pump starts, it continuously draws in air. The drawn air passes through the first connecting pipe and the second connecting pipe in sequence and enters the horizontal pipe. The gas in the horizontal pipe is dispersed and released from different air outlets. The gas released from the air outlets cools the hot-pressed polyurethane board, accelerating the heat dissipation of the polyurethane board. This prevents the polyurethane board from deforming, twisting, or becoming uneven. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-3 A polyurethane embossing device includes a support platform 1, a limit frame 2 connected to the upper end of the support platform 1, a support frame 3 fixedly connected to the upper end of the support platform 1, a movable block 4 slidably connected to the support frame 3, a driving component 5 connected to the support frame 3 for moving the movable block 4 horizontally, an electric telescopic rod 6 fixedly connected to the upper end of the movable block 4, the telescopic end of the electric telescopic rod 6 passing through the movable block 4 and fixedly connected to a mounting frame 7, an embossing roller 8 rotatably connected to the mounting frame 7, and a pump 9 fixedly connected to the upper end of the movable block 4. The outlet end of the pump 9 is connected to... A first connecting pipe 10 is provided, and a second connecting pipe 11 is slidably inserted into one end of the first connecting pipe 10. The second connecting pipe 11 is connected to the mounting bracket 7 through the fixing plate 12. One end of the second connecting pipe 11 is connected to a horizontal pipe 13. The bottom end of the horizontal pipe 13 is connected to an air outlet pipe 14. Several air outlet pipes 14 are provided and are evenly distributed along the length direction of the horizontal pipe 13. One end of each air outlet pipe 14 is inclined downward. An air duct 16 is provided on the support platform 1. Several heat dissipation holes 15 are provided at the upper end of the air duct 16. The several heat dissipation holes 15 are all located within the limiting frame 2.

[0021] Work process:

[0022] The polyurethane board is placed in the limiting frame 2, which limits its movement. After the embossing roller 8 is started, it heats up. The electric telescopic rod 6 drives the mounting frame 7 to move downward a set distance. The mounting frame 7 drives the embossing roller 8 to move downward. After the embossing roller 8 moves downward a set distance, it extrudes the polyurethane board. At the same time, after the mounting frame 7 moves downward, it also drives the fixing plate 12 to move. The fixing plate 12 drives the second connecting pipe 11 to move downward. The second connecting pipe 11 drives the horizontal pipe 13 to move. The horizontal pipe 13 drives the air outlet pipe 14 to move. The horizontal pipe 13 moves synchronously with the embossing roller 8.

[0023] After the embossing roller 8 moves downward a set distance, the drive unit 5 starts and drives the movable block 4 to move horizontally. After the movable block 4 moves, the embossing roller 8 rolls and embosses on the polyurethane board. At the same time, the pump 9 is powered on and starts. After the pump 9 starts, it continuously draws in air. The drawn air passes through the first connecting pipe 10 and the second connecting pipe 11 in sequence and enters the horizontal pipe 13. The gas in the horizontal pipe 13 is dispersed and released from different air outlet pipes 14. The gas released from the air outlet pipes 14 cools down the hot-pressed polyurethane board, accelerating the heat dissipation of the polyurethane board. Several heat dissipation holes 15 are connected to the air duct 16. The heat on the polyurethane board passes through the several heat dissipation holes 15 and enters the air duct 16, improving the heat dissipation of the polyurethane board. This prevents the polyurethane board from deforming and avoids problems such as twisting or unevenness.

[0024] Example 2: In Example 1, when gas is released through the exhaust pipe 14 to dissipate heat from the polyurethane board, the gas released from the exhaust pipe 14 flows at a high speed, generating a large impact force upon contact with the polyurethane board, which can easily cause the polyurethane board to bend. (Refer to...) Figure 3 and Figure 5 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a buffer mechanism 17 for reducing the intensity of gas impact is connected to the fixed plate 12. The buffer mechanism 17 includes an open box 171, which is fixedly connected to the fixed plate 12. The opening of the open box 171 is located below the gas outlet pipe 14. A strip-shaped hole is opened at the bottom end of the open box 171, and a fixing net 172 is fixedly connected to the strip-shaped hole. A plurality of air holes 173 are evenly spaced along the length direction at one bottom side of the open box 171. The gas released from the gas outlet pipe 14 enters the open box 171 and the open box 171 buffers the gas. Part of the gas is released from the air holes 173, and the other part of the gas is buffered and slowed down by the fixing net 172 before contacting the polyurethane board, thus avoiding a large impact force on the polyurethane board and preventing the polyurethane board from bending.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
