Description

Technical Field

[0001] This utility model relates to the field of extruded board production and processing technology, and in particular to an extruded board cooling device. Background Technology

[0002] Extruded polystyrene (XPS) boards are materials formed by continuous extrusion and foaming using a special process. XPS boards have advantages such as high thermal resistance and low expansion ratio, so they are often used as insulation materials in my country's construction projects. After processing or after one step of processing, XPS boards need to be heated and cooled before proceeding to the next step to prevent the temperature from being too high for a long time and damaging the internal structure of the XPS board. Therefore, cooling devices are used to cool and lower the temperature of the XPS boards.

[0003] For example, Chinese patent application CN202321168648.0 discloses a cooling device for extruded polystyrene (XPS) boards. Specifically, the XPS board is moved by a front-end conveyor to a rotating roller above a cooling tank. Between two limiting members, cold water in the cooling tank evaporates and absorbs heat, carrying away heat from the surface of the XPS board, thus lowering its surface temperature. A cooling fan blows cold air evenly onto the surface of the XPS board through multiple air outlets in the air duct, promoting air circulation and accelerating the cooling process. However, prolonged heat exchange between the cold water and the XPS board causes the water temperature to rise, reducing the cooling efficiency. To address this, the cap on the water outlet pipe on the side of the cooling tank can be unscrewed to release the heated cold water. Then, the valve at the inlet can be opened, with the other side connected to a tap water pipe, to refill the cooling tank with cold water and maintain the cooling rate of the XPS board. However, the following technical problems have been found:

[0004] Because the air duct is directly exposed to the outside, the cool air dissipates quickly in the hot summer, causing the extruded polystyrene board to cool down slowly. Utility Model Content

[0005] To address the problem mentioned in the background art of slow cooling of extruded polystyrene boards due to rapid dissipation of cold air in summer, this utility model provides the following technical solution:

[0006] An extruded polystyrene board cooling device includes a conveying device;

[0007] The conveying device is equipped with a cooling device for cooling the extruded board.

[0008] The conveying device includes a conveying platform for conveying extruded polystyrene boards. The upper end of the conveying platform is equipped with a protective shell to prevent the rapid loss of cold air. The left and right ends of the protective shell are provided with inlets to facilitate the conveying of the extruded polystyrene boards.

[0009] The protective shell is equipped with baffles at both the left and right ends for adjusting the size of the feed inlet opening.

[0010] Furthermore, a limiting tube is installed at the upper end of the protective shell, and a cooling fan is installed at the upper end of the protective shell to facilitate cooling of the interior of the protective shell. A three-way pipe is installed at the output end of the cooling fan, and ventilation hoses are installed at both ends of the three-way pipe.

[0011] Furthermore, a water tank is installed at the bottom of the conveyor platform, with an inlet pipe installed at the right end of the water tank and an outlet pipe installed at the left end of the water tank.

[0012] Furthermore, the protective shell is equipped with U-shaped rods for limiting the position of the baffle at both the left and right ends. The U-shaped rods have multiple positioning holes machined in the middle. The baffle has sliders installed at both the front and rear ends. The U-shaped rods have positioning pins for limiting the position of the sliders installed in the middle.

[0013] Furthermore, the cooling device includes a cold air box, the upper end of which is equipped with a connecting pipe, and the connecting pipe is connected to a ventilation hose.

[0014] Furthermore, a reinforcing rib is installed at the upper end of the cold air box, and a limiting rod is installed at both ends of the reinforcing rib to limit the position of the cold air box in conjunction with the limiting tube. A cylinder for controlling the up and down movement of the cold air box is installed in the middle of the reinforcing rib, and multiple air outlet slots are opened at the bottom of the reinforcing rib.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Cold water is continuously supplied to the water tank through the inlet pipe, allowing the water heated by the extruded polystyrene (XPS) board inside the tank to carry away heat, thus facilitating the cooling of the XPS board. The air cooler is activated, delivering cold air through a T-junction, ventilation hose, and connecting pipe to the inner cavity of the air cooler box. The cold air inside the box is then blown towards the top of the XPS board through the air outlet duct for rapid cooling. The protective outer shell prevents rapid dissipation of cold air, especially in summer. When cooling XPS boards of different thicknesses, the distance between the baffle and the conveyor table is adjusted to reduce the size of the inlet opening, further preventing rapid loss of cold air.

[0028] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0029] Please see Figures 1-4 This utility model provides a cooling device for extruded polystyrene boards, including a conveying device 001.

[0030] The conveying device 001 includes a conveyor table 100 for conveying extruded polystyrene (XPS) boards. After production, the XPS boards are conveyed from the right end to the left end of the conveyor table 100. A protective shell 110 is fixedly installed on the upper end of the conveyor table 100 to prevent rapid loss of cold air. The protective shell 110 prevents cold air from dissipating quickly in summer, allowing it to remain inside the shell for an extended period, thus facilitating rapid cooling of the XPS boards. The protective shell 110 has inlets 111 at both ends for conveying the XPS boards. Limiting tubes 112 are fixedly installed on the upper left and right ends of the protective shell 110 to limit the movement of the limiting rod 221.

[0031] A cooler 120 is fixedly installed at the upper end of the protective shell 110 to facilitate cooling of the interior of the protective shell 110. A three-way pipe 121 is fixedly installed at the output end of the cooler 120. Ventilation hoses 122 are fixedly installed at the two output ends of the three-way pipe 121, and the ventilation hoses 122 are connected to the interior of the protective shell 110 to facilitate the delivery of cold air to the interior of the cold air box 200.

[0032] A water tank 130 is fixedly installed at the bottom of the conveyor table 100. The upper end of the water tank 130 is open and not sealed to facilitate better cooling of the lower end of the extruded polystyrene board. A water inlet pipe 131 is fixedly installed at the right end of the water tank 130, and a water outlet pipe 132 is installed at the fixed left end of the water tank 130. Cold water is continuously supplied to the interior of the water tank 130 through the water inlet pipe 131, so that the water heated by the extruded polystyrene board inside the water tank 130 carries away the heat, thereby facilitating better cooling of the extruded polystyrene board.

[0033] The protective housing 110 is equipped with baffles 140 at both the left and right ends for adjusting the opening size of the feed inlet 111. Both the left and right ends of the protective housing 110 are fixedly equipped with U-shaped rods 150 for limiting the position of the baffles 140, and the baffles 140 slide in the groove in the middle of the U-shaped rods 150.

[0034] The U-shaped rod 150 has multiple positioning holes 151 machined in the middle. The front and rear ends of the baffle 140 are fixedly installed with sliders 141, and the middle of the sliders 141 is provided with limiting holes. The middle of the U-shaped rod 150 is provided with positioning pins 160 for limiting the sliders 141. When cooling extruded boards of different thicknesses, the opening size of the feed inlet 111 is reduced by adjusting the distance between the baffle 140 and the conveyor table 100, so that the cold air is not easily lost quickly. The positioning pins 160 are inserted into the middle holes of the U-shaped rod 150 and the sliders 141 to stabilize the baffle 140.

[0035] The conveying device 001 is equipped with a cooling device 002 for cooling the extruded polystyrene board. The cooling device 002 includes a cold air box 200, which is located in the cavity formed between the protective shell 110 and the conveying table 100. Connecting pipes 210 are fixedly installed at the left and right ends of the upper part of the cold air box 200, and the connecting pipes 210 are connected to the ventilation hoses 122. When cooling the extruded polystyrene board, the cold air fan 120 is started, so that cold air is delivered to the inner cavity of the cold air box 200 through the three-way pipe 121, the ventilation hose 122 and the connecting pipe 210.

[0036] A reinforcing rib 220 is fixedly installed at the upper end of the cold air box 200. Limiting rods 221, which cooperate with the limiting tube 112 to limit the movement of the cold air box 200, are fixedly installed at both ends of the reinforcing rib 220. The limiting rods 221 slide in the middle of the limiting tube 112. A cylinder 222, used to control the up-and-down movement of the cold air box 200, is fixedly installed in the middle of the reinforcing rib 220. The upper end of the cylinder 222 is fixedly installed on the top inner wall of the protective shell 110, and the telescopic end of the cylinder 222 is fixedly installed in the middle of the reinforcing rib 220, so that after the cylinder 222 is activated, it drives the cold air box 200 to move up and down, adjusting the distance between the extruded polystyrene board and the cold air box 200 according to the thickness of the extruded polystyrene board. Multiple air outlet slots 230 are opened at the bottom of the reinforcing rib 220. The cold air inside the cold air box 200 is blown towards the upper end of the extruded polystyrene board through the air outlet slots 230 to rapidly cool the extruded polystyrene board.

[0037] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
