Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton production equipment, and more specifically, to a temperature regulating device for pearl cotton production. Background Technology

[0002] In the production process, EPE foam is foamed using an EPE foaming machine. A die is installed at the front of the machine, extruding molten material into a ring-shaped sheet of EPE foam of a certain thickness. The ring-shaped sheet is then cut open by a cutting device, flattened, and rolled up into a roll. To ensure that the molten EPE foam solidifies after being discharged from the die, a cooling temperature regulating device is installed on the die for cooling. In existing technology, the die is circular, and the cooling temperature regulating device is water-cooled. This involves wrapping a cold water pipe around the die and covering the pipe with a protective cover. A circulation system connects the pipe to the cold water pipe, achieving water cooling circulation and thus cooling.

[0003] However, the inner wall of the cold water pipe is smooth. When the coolant flows in the spiral pipe, the flow velocity of the coolant near the inner wall of the cold water pipe (i.e., the outer wall of the mold head) is less than that at the center of the pipe due to the structure of the spiral bend of the cold water pipe. This creates a situation similar to laminar flow in a straight pipe, resulting in poor heat exchange and low cooling efficiency, which increases the running time of the temperature control device. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a temperature regulating device for EPE foam production, comprising a first sleeve and a second sleeve. The first sleeve is adapted to be fitted onto a die head. A spiral groove is formed on the outer wall of the first sleeve for coolant to flow through. A plurality of baffles are provided on the side of the spiral groove near the inner wall of the first sleeve, and the plurality of baffles are arranged at intervals along the extension direction of the spiral groove. The second sleeve is fitted onto the first sleeve and is tightly fitted and fixedly connected to the first sleeve. A fluid inlet and a fluid outlet are respectively provided at both ends of the first sleeve, and both the fluid inlet and the fluid outlet are connected to the spiral groove.

[0005] Optionally, the first sleeve is made of aluminum.

[0006] Optionally, the spoiler is inclined within the spiral groove.

[0007] Optionally, the baffle plate extends at an angle towards the second sleeve, gradually moving in the opposite direction to the coolant flow direction.

[0008] Optionally, the tilt angles of two adjacent spoilers are different.

[0009] Optionally, the first sleeve is provided with a first end plate and a second end plate at both ends, and the first end plate and the second end plate are precisely welded to the first sleeve and the second sleeve.

[0010] Optionally, the first end plate is provided with a first pipe communicating with the fluid inlet, and the second end plate is provided with a second pipe communicating with the fluid outlet.

[0011] Optionally, the second sleeve is made of aluminum.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. By setting multiple baffles, the side of the spiral groove near the inner wall of the first sleeve forms an uneven structure. When the coolant flows in the spiral groove, it will generate turbulence and increase the turbulence effect. Compared with laminar flow, turbulence has high-frequency vortex phenomenon, which can enhance the heat exchange between the fluid and the wall and improve the cooling efficiency.

[0014] 2. When the coolant flows, the baffles are tilted and open at a certain angle. The coolant will collide with the baffles and flow back. At the same time, different tilt angles of the baffles can make the coolant mix more strongly, enhance the turbulence effect, and further improve the cooling efficiency.

[0015] 3. Both the first and second sleeves are made of aluminum, which has a good heat dissipation effect and improves the heat exchange effect. The threaded groove is opened on the outer wall of the first sleeve, and then the second sleeve is fitted on the first sleeve, which makes it easier to process the threaded groove and reduces the production difficulty.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-2 This application will be described in further detail.

[0020] This utility model embodiment provides a temperature control device for pearl cotton production, referring to... Figure 1 and Figure 2The temperature control device for EPE foam production includes a first sleeve 1 and a second sleeve 2. The first sleeve 1 is adapted to be fitted and fixed on the die head, and the second sleeve 2 is fitted on the first sleeve 1 and is tightly fitted and fixedly connected to the first sleeve 1. The outer wall of the first sleeve 1 is provided with a spiral groove 11 for the coolant to flow through. Multiple baffles 12 are provided on the side of the spiral groove 11 near the inner wall of the first sleeve 1, thereby generating turbulence when the coolant flows in the spiral groove 11, enhancing the heat exchange between the fluid and the wall surface, and improving the cooling efficiency.

[0021] The two ends of the spiral groove 11 pass through the openings at both ends of the first sleeve 1, thus forming a fluid inlet and a fluid outlet. The coolant enters from the fluid inlet, flows through the entire spiral groove 11, and is discharged from the fluid outlet, thereby carrying away the heat of the die head and achieving a cooling effect.

[0022] Reference Figure 1 and Figure 2 Both the first sleeve 1 and the second sleeve 2 are made of aluminum, resulting in better heat dissipation and improved heat exchange. When fitted together, the first sleeve 1 and the second sleeve 2 form a tight fit, allowing the coolant to flow directionally along the path of the spiral groove 11. This design also makes the threaded groove machining easier and less difficult. The first sleeve 1 and the second sleeve 2 are then welded together using tungsten inert gas welding. It is worth noting that because aluminum has a certain deformation capacity when heated, the first sleeve 1 and the second sleeve 2 will deform under the heating of the die, resulting in a tighter fit after fitting. This allows the coolant to move more stably within the spiral groove 11, reducing the risk of coolant leakage from the wall thickness between adjacent spiral grooves 11.

[0023] Multiple baffles 12 are arranged at intervals along the path of the spiral groove 11, so that the coolant can collide with the corresponding baffles 12 multiple times in the spiral groove 11, thereby generating turbulent structures in multiple places and enhancing the effect of generating turbulence.

[0024] Reference Figure 1 and Figure 2 The baffle 12 is inclinedly disposed within the spiral groove 11 and welded to the spiral groove 11 by tungsten inert gas welding. This reduces the complexity of the first sleeve 1 mold and lowers costs. Specifically, the baffle 12 gradually extends in the opposite direction of the coolant flow towards the second sleeve 2 without protruding from the spiral groove 11; that is, the baffle 12 opens at a certain angle in the opposite direction of the coolant flow. Thus, the coolant impacts the baffle 12 during flow, creating a backflow and generating high-frequency vortices, enhancing turbulence and improving cooling efficiency.

[0025] In one embodiment, the different inclination angles of adjacent baffles 12 along the path of the spiral groove 11 enable stronger mixing of the coolant, further enhancing the turbulence effect. In another embodiment, the inclination angles of the baffles 12 are all different. In yet another embodiment, the inclination angles of the baffles 12 are all the same.

[0026] In addition, the first sleeve 1 has a first end plate 13 and a second end plate 14 at its two axial ends, respectively. The first end plate 13 has a first pipe 15 communicating with the fluid inlet, and the second end plate 14 has a second pipe 16 communicating with the fluid outlet. The first pipe 15 and the second pipe 16 are connected to the fluid circulation device through corresponding hoses, so that the coolant can be circulated.

[0027] Reference Figure 1 and Figure 2 The first end plate 13 is an annular end plate, concentrically arranged with the first sleeve 1. The inner diameter of the first end plate 13 is equal to the inner diameter of the first sleeve 1, and the outer diameter of the first end plate 13 is equal to the outer diameter of the second sleeve 2. The outer diameter of the first end plate 13 is integrally formed and bent with an annular first flange, which is fitted onto the second sleeve 2, thereby enabling the first end plate 13, the second sleeve 2, and the first sleeve 1 to form a preliminary positioning connection. The first end plate 13 is precisely welded to the first sleeve 1 and the second sleeve 2 by tungsten inert gas welding.

[0028] Reference Figure 1 and Figure 2 Similarly, the second end plate 14 is an annular end plate, concentrically arranged with the first sleeve 1. The inner diameter of the second end plate 14 is equal to the inner diameter of the first sleeve 1, and the outer diameter of the second end plate 14 is equal to the outer diameter of the second sleeve 2. The outer diameter of the second end plate 14 is integrally formed and bent with an annular second flange, which is fitted onto the second sleeve 2, thereby enabling the second end plate 14, the second sleeve 2, and the first sleeve 1 to form a preliminary positioning connection. The second end plate 14 is precisely welded to the first sleeve 1 and the second sleeve 2 by tungsten inert gas welding. After the first sleeve 1 and the second sleeve 2 are welded, and the first end plate 13 and the second end plate 14 are precisely welded to the first sleeve 1 and the second sleeve 2, an airtightness test is performed on the temperature regulating device to ensure the airtightness after welding, allowing the coolant to flow directionally within the spiral groove 11 without leakage.

[0029] The implementation principle of the temperature regulating device for pearl cotton production in this application embodiment is as follows: Multiple baffles 12 are installed to create an uneven structure on the side of the spiral groove 11 near the inner wall of the first sleeve 1. When the coolant flows, the baffles 12 are tilted and open at a certain angle, causing the coolant to collide with the baffles 12 and flow back, generating turbulence. Simultaneously, the different tilt angles of the baffles 12 enable stronger mixing of the coolant, generating high-frequency vortices, enhancing the turbulence effect, strengthening heat exchange between the fluid and the wall surface, and improving cooling efficiency.
