Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and specifically discloses a cooling device for EPP production. Background Technology

[0002] EPP is an abbreviation for expanded polypropylene, a new type of foamed plastic. EPP is a polypropylene foam material, a high-performance, highly crystalline polymer / gas composite material. With its unique and superior properties, it has become the fastest-growing environmentally friendly new pressure-resistant, cushioning, and heat-insulating material. EPP is also an environmentally friendly material that can be recycled and reused, can be naturally degraded, and will not cause white pollution. EPP sheets are produced at high temperatures and need to be cooled down to facilitate further operations.

[0003] Currently, the most common cooling methods used in the industry are natural cooling, forced air cooling, or water mist spray cooling. However, natural cooling takes too long, severely restricting production efficiency; forced air cooling has the disadvantages of insufficient cooling intensity and high energy consumption, especially for thicker products, where uneven cooling can easily generate internal thermal stress, leading to product deformation or shrinkage; while water mist spray cooling improves efficiency, it still cannot achieve rapid and uniform heat exchange for the entire product, especially the core parts, and water droplet splashing also makes it difficult to guarantee the stability of the cooling effect. Therefore, a cooling device for EPP production is needed to solve this problem. Utility Model Content

[0004] This invention proposes a cooling device for EPP production, which uses a metal mesh belt that operates synchronously from top to bottom to forcibly clamp the EPP product and completely immerse it in water, fundamentally solving the problem of uneven cooling caused by its low density and floating, and achieving efficient and uniform immersion cooling.

[0005] This utility model is implemented as follows: a cooling device for EPP production includes a water tank containing cooling water. The outer wall of the water tank is provided with an inlet and an outlet. The inner wall of the water tank is rotatably connected to two symmetrically distributed first rollers via a rotating shaft. The outer walls of the two first rollers are provided with a first conveyor belt. The outer wall of the water tank is equipped with a first drive motor whose output end is fixedly connected to one of the first rollers. The upper end face of the water tank is fixedly connected to a mounting plate via support legs. A pressing mechanism is provided on the lower side of the mounting plate. The clamping mechanism includes a bracket disposed below the mounting plate. An electric push rod with its output end fixedly connected to the bracket is mounted on the upper surface of the mounting plate. Two symmetrically distributed second rollers are rotatably connected to the lower side of the bracket via a rotating shaft. A second conveyor belt is disposed on the outer wall of the two second rollers. A second drive motor with its output end fixedly connected to one of the second rollers is mounted on the outer wall of the bracket.

[0006] As a preferred embodiment of the cooling device for EPP production according to this utility model, the inner wall of the water tank is provided with two limiting rollers located below the first roller shaft. The limiting rollers abut against the lower half of the first conveyor belt. The front and rear end faces of the inner wall of the water tank are rotatably connected to two limiting wheels located below the first roller shaft through a rotating shaft. The limiting wheels abut against the upper half of the first conveyor belt.

[0007] As a preferred embodiment of the cooling device for EPP production according to this utility model, the inner wall of the water tank is fixedly connected with two baffles.

[0011] As a preferred embodiment of the cooling device for EPP production according to this utility model, the outer wall of the water tank is equipped with a controller, and the first drive motor, the second drive motor and the electric push rod are all electrically connected to the controller.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-4 A cooling device for EPP production includes a water tank 1 containing cooling water. The outer wall of the water tank 1 is provided with an inlet 15 and an outlet 16. The inner wall of the water tank 1 is rotatably connected to two symmetrically distributed first rollers 2 via a rotating shaft. The outer wall of the two first rollers 2 is provided with a first conveyor belt 4. The outer wall of the water tank 1 is equipped with a first drive motor 5 whose output end is fixedly connected to one of the first rollers 2. The upper end face of the water tank 1 is fixedly connected to a mounting plate 8 via a support leg. A pressing mechanism is provided on the lower side of the mounting plate 8. The clamping mechanism includes a bracket 10 disposed below the mounting plate 8. An electric push rod 9 with its output end fixedly connected to the bracket 10 is mounted on the upper end surface of the mounting plate 8. Two symmetrically distributed second rollers 11 are rotatably connected to the lower side of the bracket 10 via a rotating shaft. A second conveyor belt 12 is disposed on the outer wall of the two second rollers 11. A second drive motor 13 with its output end fixedly connected to one of the second rollers 11 is mounted on the outer wall of the bracket 10.

[0022] In this embodiment: the high-temperature EPP product is first placed on the first conveyor belt 4 driven by the first drive motor 5 and the first roller 2, and then enters the water tank 1 filled with cooling water. At the same time, the clamping mechanism controlled by the electric push rod 9 starts to work, and its second drive motor 13 drives the second roller 11 to drive the second conveyor belt 12 to operate synchronously. Together with the first conveyor belt 4 below, the EPP product is clamped, overcoming its buoyancy and making it completely submerged in the cooling water for uniform and efficient forced water cooling. After cooling, the product is conveyed to the other end of the water tank 1 and discharged, completing the entire cooling process. This utility model effectively overcomes the characteristics of low density and easy floating of EPP products by using the first conveyor belt 4 and the second conveyor belt 12 that operate synchronously, and realizes forced immersion cooling. It solves the technical problems of low efficiency and poor uniformity of traditional spray cooling methods.

[0023] As a technical optimization of this utility model, the inner wall of the water tank 1 is provided with two limiting rollers 3 located below the first roller shaft 2. The limiting rollers 3 abut against the lower half of the first conveyor belt 4. The front and rear end faces of the inner wall of the water tank 1 are rotatably connected by two limiting wheels 6 located below the first roller shaft 2 through a rotating shaft. The limiting wheels 6 abut against the upper half of the first conveyor belt 4.

[0024] In this embodiment, the first conveyor belt 4 is limited by two first limiting rollers 3 and multiple limiting wheels 6, so that the first conveyor belt 4 is U-shaped as a whole, which facilitates the conveying of EPP products to the cooling water.

[0025] As a technical optimization of this utility model, two baffles 7 are fixedly connected to the inner wall of the water tank 1.

[0026] In this embodiment, the baffle 7 facilitates the separation of the limiting wheel 6 from the EPP product, preventing the EPP product from getting stuck between the limiting wheel 6 and the first conveyor belt 4.

[0027] As a technical optimization of this utility model, both the first conveyor belt 4 and the second conveyor belt 12 are metal mesh structures.

[0028] In this embodiment: by setting both the first conveyor belt 4 and the second conveyor belt 12 as metal mesh structures, the use of metal mesh structures for the first conveyor belt 4 and the second conveyor belt 12 can ensure that the cooling water can fully penetrate the contact product to achieve uniform and efficient cooling, and can also quickly drain water through the mesh to facilitate the subsequent dehydration process.

[0029] As a technical optimization of this utility model, the second drive motor 13 is a waterproof motor.

[0030] In this embodiment, the second drive motor 13 has a waterproof rating of IP67, which fundamentally avoids the risk of short circuit, damage or electric shock caused by water ingress into the motor, and ensures the continuity and safety of the entire pressing mechanism and cooling process.

[0031] As a technical optimization of this utility model, two symmetrically distributed limiting rods 14 are fixedly connected to the upper end face of the bracket 10, and both limiting rods 14 are slidably connected to the mounting plate 8.

[0032] In this embodiment, the limiting rod 14 facilitates the limiting of the bracket 10, making the up-and-down movement of the bracket 10 stable.

[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of the water tank 1, and the first drive motor 5, the second drive motor 13 and the electric push rod 9 are all electrically connected to the controller.

[0034] In this embodiment, the controller facilitates the normal operation of the first drive motor 5, the second drive motor 13, and the electric push rod 9.

[0035] The working principle and usage process of this utility model are as follows: During use, the high-temperature EPP product is first placed on the first conveyor belt 4, driven by the first drive motor 5 and the first roller shaft 2, and then enters the water tank 1 filled with cooling water. Simultaneously, the clamping mechanism, whose height is controlled by the electric push rod 9, begins to operate. Its second drive motor 13 drives the second roller shaft 11, which in turn drives the second conveyor belt 12 to rotate synchronously. Together with the first conveyor belt 4 below, the EPP product is clamped, overcoming its buoyancy and completely submerging it in the cooling water for uniform and efficient forced water cooling. After cooling, the product is conveyed to the other end of the water tank 1 and discharged, completing the entire cooling process. This utility model effectively overcomes the characteristics of low density and easy floating of EPP products by using the synchronously operating first conveyor belt 4 and second conveyor belt 12, achieving forced immersion cooling. It solves the technical problems of low efficiency and poor uniformity of traditional spray cooling methods.
