Abstract
Description
Technical Field
[0001] This application relates to the field of EPS foam board processing technology, and in particular to a cooling device for EPS foam board production. Background Technology
[0002] In the molding process of EPS foam boards, high-temperature steam is used for foaming and shaping. To improve the dimensional stability of the product, reduce internal stress, and speed up the production cycle, the cooling process is particularly crucial. Immersion cooling in water is an efficient and easy-to-operate method, especially suitable for medium-thickness or custom-structured EPS foam boards.
[0003] Currently, when using cooling water to cool EPS foam boards, the EPS foam boards are generally directly immersed in a cooling tank, cooled to full contact with the cooling water, and then manually removed. Alternatively, a mesh support frame is used to support the EPS foam boards, and they can be removed by simply pulling the support frame. However, this direct removal method causes some cooling water to be carried out with the EPS foam boards, resulting in water spillage in the factory and waste. Therefore, to solve the aforementioned problem of cooling water waste, a cooling device for EPS foam board production has been designed to address this issue. Utility Model Content
[0004] To address this problem, this application provides a cooling device for EPS foam board production.
[0005] The technical solution provided in this application for a cooling device in EPS foam board production is as follows:
[0006] A cooling device for EPS foam board production includes a cooling box and a support frame fixed above it. A linear motor is mounted on the upper end of the support frame, a movable seat is slidably mounted on the linear motor, an electric push rod is fixedly connected to the lower end of the movable seat, and a swinging component is mounted on the lower end of the electric push rod.
[0007] The swinging component includes a gear fixedly installed in the middle of the upper end of the fixed frame, and two mounting plates installed on the side wall of the support frame. The two mounting plates are arranged vertically, and racks for driving the gear to rotate are fixedly connected to the front two sides of the mounting plates.
[0008] Preferably, the upper middle part of the gear is rotatably connected to the mounting block, and the upper end of the mounting block is fixedly connected to the output end of the electric push rod.
[0009] Preferably, a torsion spring is fixedly connected to the upper end of the gear, and a mounting block is fixedly connected to the upper end of the torsion spring.
[0010] Preferably, a fixed frame is installed at the lower end of the swing component, and a clamping plate is slidably installed at the lower end of the fixed frame.
[0011] Preferably, the two screw rods are rotatably connected on both sides of the fixed frame, and the two screw rods are fixedly connected close to each other at one end.
[0012] Preferably, a movable plate is threaded onto the lead screw, and a clamping plate is fixedly connected to the lower end of the movable plate. The clamping plate has a plurality of mesh holes.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] In this invention, by using a structure consisting of gears, racks, mounting plates, and mounting blocks, after the EPS foam board has cooled, the meshing of the gears and racks causes the clamped EPS foam board to rotate continuously, causing the cooling water adhering to the surface of the EPS foam board to be thrown off and fall into the cooling box. This speeds up the drying process of the EPS foam board after cooling and avoids the waste of cooling water.
[0015] Furthermore, by rotating the EPS foam board inside the cooling box, the continuous rotation allows the EPS foam board to continuously renew its contact surface in the water, resulting in better and faster heat conduction and accelerating the cooling process of the EPS foam board.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0021] This application discloses a cooling device for EPS foam board production. (Refer to...) Figure 1-3 A cooling device for EPS foam board production includes a cooling box 1 and a support frame 2 fixed above it. A linear motor 3 is installed on the upper end of the support frame 2. A movable seat 4 is slidably installed on the linear motor 3. An electric push rod 5 is fixedly connected to the lower end of the movable seat 4. A swinging component is installed on the lower end of the electric push rod 5.
[0022] The swinging component includes a gear 8 fixedly installed in the middle of the upper part of the fixed frame 9, and two mounting plates 6 installed on the side wall of the support frame 2. The two mounting plates 6 are arranged vertically. The front sides of the mounting plates 6 are fixedly connected to racks 7 for driving the gear 8 to rotate. The middle of the upper part of the gear 8 is rotatably connected to a mounting block 51. The upper end of the mounting block 51 is fixedly connected to the output end of the electric push rod 5. The upper end of the gear 8 is fixedly connected to a torsion spring 81. The upper end of the torsion spring 81 is fixedly connected to the mounting block 51.
[0023] A linear motor 3 can be used to drive the moving seat 4 to move, which in turn drives the gear 8, the fixed frame 9, and the clamped EPS foam board to move. During the movement, the gear 8 meshes with the rack 7, causing the gear 8 to drive the lower fixed frame 9 to rotate, which in turn drives the torsion spring 81 to rotate. The fixed frame 9 then drives the EPS foam board to rotate. When the rack 7 separates from the gear 8, the torsion spring 81 will drive the gear 8 to rotate back to its original position, causing the EPS foam board to rotate back to its original position. This process is repeated, so that the gear 8 meshes with the rack 7 again and drives the EPS foam board to rotate, shaking off the cooling water adhering to the surface of the EPS foam board and letting it fall into the cooling box 1, thereby accelerating the drying process of the EPS foam board after cooling.
[0024] By adopting the above technical solution, a fixed frame 9 is installed at the lower end of the swing component, and a clamping plate 11 is slidably installed at the lower end of the fixed frame 9. The two sides of the fixed frame 9 are rotatably connected to screw rods 91, and the two screw rods 91 are fixedly connected to each other at one end. A moving plate 10 is threadedly connected to the screw rod 91, and the lower end of the moving plate 10 is fixedly connected to the clamping plate 11. The clamping plate 11 has several mesh holes for drainage, so that the cooling water can fully contact the EPS foam board, which is convenient for cooling the EPS foam board. In use, the EPS foam board that needs to be cooled is placed between the two clamping plates 11, and then the screw rod 91 is rotated to move the moving plate 10. The moving plate 10 moves the clamping plate 11 and clamps the EPS foam board after moving, which is convenient for fixing the EPS foam board.
[0025] The implementation principle of a cooling device for EPS foam board production according to an embodiment of this application is as follows: The EPS foam board to be cooled is placed between two clamping plates 11. Then, the lead screw 91 is rotated, causing the lead screw 91 to drive the moving plate 10 to move. The moving plate 10 drives the clamping plate 11 to move and clamp the EPS foam board after moving. Then, the linear motor 3 is started, causing the linear motor 3 to drive the moving seat 4 to move to the upper end of the cooling box 1, and causing the electric push rod 5 and the lower fixed frame 9 to move together, so that the clamped EPS foam board is fixed. Then, the electric push rod 5 is started, and the electric push rod 5 drives the mounting block 51, gear 8 and fixed frame 9 to descend, so that the EPS foam board clamped at the lower end descends into the cooling box 1 and comes into contact with the cooling water, thereby performing cooling treatment. At this time, the gear 8 descends and becomes flush with the rack 7 on the mounting plate 6 at the lower end.
[0026] When the EPS foam board is stationary in water, a temperature gradient (boundary layer) forms on the surface of the board. This boundary layer reduces the efficiency of heat transfer from the board to the water. Therefore, the linear motor 3 is restarted to move the moving seat 4, which in turn moves the gear 8, the fixed frame 9, and the clamped EPS foam board. During the movement, the gear 8 meshes with the rack 7, causing the lower fixed frame 9 to rotate. This, in turn, causes the torsion spring 81 to twist, and the fixed frame 9 rotates the EPS foam board. When the rack 7 separates from the gear 8, the torsion spring 81 drives the gear 8 to rotate back to its original position, causing the EPS foam board to rotate back to its original position. This process is repeated, continuously causing the EPS foam board to rotate within the cooling box 1. This continuous rotation allows the EPS foam board to continuously renew its contact surface in the water, resulting in better and faster heat conduction and accelerating the cooling process of the EPS foam board.
[0027] After cooling, the electric push rod 5 can be started first to raise the EPS foam board held on the fixed frame 9 and the clamping plate 11 to separate it from the cooling water. After the gear 8 rises, the upper rack 7 is aligned with it. Then, the linear motor 3 is used again to drive the gear 8 and the EPS foam board to move. After the gear 8 meshes with the rack 7, it drives the EPS foam board to rotate again, and the cooling water attached to the surface of the EPS foam board is shaken off and falls into the cooling box 1, thereby accelerating the drying process of the EPS foam board after cooling.
