Description

Technical Field

[0001] The utility model relates to the field of pearl cotton manufacturing, and more specifically to an oil temperature conduction unit heating device for a pearl cotton extruder die head. Background Art

[0002] Pearl cotton is a commonly used material in the packaging field. It mainly plays a cushioning role in packaging. It needs to be foamed during its production process and then extruded from the die of the extruder after foaming. The extrusion die needs to be heated during the molding process. In the prior art, the extruder foaming extrusion die is generally heated by an electric heating coil. This heating method has many problems, such as uneven and unstable heating and long heating time. In addition, electric sparks are easily generated during use, which may cause safety hazards and the fire protection is not up to standard.

[0003] China Patent Authorization Announcement No.: CN218196850U provides an oil temperature conduction unit heating device for the pearl cotton extruder die head. The solution is to install the oil pipe in the thermal conductive silicone layer, and the thermal conductive silicone layer is in full contact with the pearl cotton extruder die head. In this way, the heat of the oil pipe can be evenly transferred to the pearl cotton extruder die head through the thermal conductive silicone layer, and the heating is more uniform, and the heat conduction effect is better. There is no need to groove the outer wall of the pearl cotton extruder die head to fix the oil pipe, avoiding the modification of the pearl cotton extruder die head. In addition, the unit installation structure can be used to select different numbers and sizes of oil temperature conduction units for installation according to the structure of the pearl cotton extruder die head, and the versatility is strong. The heating unit can circulate and heat the hot oil in the oil pipe, and can stably maintain the temperature of the pearl cotton extruder die head.

[0004] However, the mounting sleeve in the scheme can be fastened by screws so that it can be fixed to the outer end of the extruder die of different calibers. However, unless the outer diameter of the extruder die is exactly the same as the inner diameter of the mounting sleeve, there must be a gap between the thermally conductive silicone layer and the extruder die. These gaps will cause the heat conducted by the silicone layer to be unable to be quickly conducted to the extruder die, thereby reducing the heating efficiency and may cause uneven heating inside the extruder die, affecting its normal operation. Therefore, in view of the above problems, an oil temperature conduction unit heating device for the pearl cotton extruder die is proposed. Utility Model Content

[0038] Example:

[0039] See also Figure 1-4 A pearl cotton extruder die head oil temperature conduction unit heating device comprises a mounting ring 1, an annular groove is provided at the inner end of the mounting ring 1, a heat-conducting silicone ring 4 matching with the annular groove is inlaid and installed at the inner end of the annular groove, an oil pipe 5 is embedded in the inner end of the heat-conducting silicone ring 4, and the oil pipe 5 is arranged in a serpentine shape. A reserved opening 2 is provided at one end of the mounting ring 1, and the ends of the mounting ring 1 located on both sides of the reserved opening 2 are connected by a screw 3 connected therethrough, and an annular filling bag 6 and an annular expansion block 7 are respectively installed at the inner end of the heat-conducting silicone ring 4, and the annular expansion block 7 is arranged in the inner cavity of the annular filling bag 6.

[0040] Pearl cotton is a commonly used material in the packaging field. It mainly plays a cushioning role in packaging. It needs to be foamed during its production process and then extruded from the die head of the extruder after foaming. The extruder die head needs to be heated during molding. In the prior art, the extruder foaming extrusion die head is generally heated by an electric heating coil.

[0041] In this solution, the user can sleeve the mounting ring 1 on the outer end of the extruder die head, and tighten the mounting ring 1 by tightening the screw 3 to fix it on the outer end of the extruder die head. The outer end of the mounting ring 1 is equipped with a heating unit, and both ends of the oil pipe 5 extend from the position of the reserved opening 2 and are connected to the heating unit to form an oil temperature conduction cycle, so that the heat of the oil pipe 5 can be evenly transferred to the extruder die head through the thermal conductive silicone ring 4, the heating is more uniform, the heat conduction effect is better, no additional modification of the extruder die head is required, and it is convenient to use.

[0042] However, in actual use, unless the outer diameter of the extruder die head is exactly the same as the inner diameter of the mounting ring 1, there must be a gap between the thermally conductive silicone ring 4 and the extruder die head. These gaps will cause the heat conducted by the thermally conductive silicone ring 4 to be unable to be quickly conducted to the extruder die head, thereby reducing the heating efficiency. Therefore, in this solution, an annular filling capsule 6 is provided at the inner end of the thermally conductive silicone ring 4. The annular filling capsule 6 is closely attached to the surface of the extruder die head. As the oil pipe 5 introduces hot oil, the thermally conductive silicone ring 4 begins to conduct heat. The annular expansion block 7 can be set to carbon nanofiber material. Carbon nanofiber is a nanomaterial with high thermal conductivity and excellent thermal expansion characteristics. It can absorb The heat of the thermally conductive silicone ring 4 is absorbed and expanded inside the annular filling capsule 6, thereby pushing the annular filling capsule 6 to expand, so that the surface of the annular filling capsule 6 fills the gap between the thermally conductive silicone ring 4 and the extruder die head. The material of the annular filling capsule 6 can be set to thermally conductive silicone, which has good elasticity and high thermal conductivity. Therefore, the heat of the oil pipe 5 can be successively transmitted to the extruder die head through the thermally conductive silicone ring 4, the annular expansion block 7 and the annular filling capsule 6, thereby reducing the gap between the thermally conductive silicone ring 4 and the surface of the extruder die head, which can effectively improve the heat conduction speed and make the surface of the extruder die head heated more evenly.

[0043] See also Figure 5 A plurality of first thermal conductive wires 8 are arranged between the annular expansion block 7 and the thermally conductive silicone ring 4, and the plurality of first thermal conductive wires 8 are arranged in a ring shape, and the two ends of the first thermal conductive wires 8 are respectively embedded in the thermally conductive silicone ring 4 and the annular expansion block 7; a plurality of second thermal conductive wires 9 are arranged between the annular filling capsule 6 and the thermally conductive silicone ring 4, and the plurality of second thermal conductive wires 9 are arranged in a ring shape, and the two ends of the second thermal conductive wires 9 are respectively embedded in the thermally conductive silicone ring 4 and the annular filling capsule 6.

[0044] The material of the first thermal wire 8 and the second thermal wire 9 can be set to copper. Copper has excellent thermal conductivity. Through the setting of the first thermal wire 8 and the second thermal wire 9, the heat in the thermally conductive silicone ring 4 can be more quickly and simultaneously conducted to the inside of the annular filling bag 6 and the annular expansion block 7, thereby reducing heat loss and improving the heating rate.

[0045] See also Figure 1 and5 A plurality of limit blocks 10 are arranged on both sides of the mounting ring 1, and the plurality of limit blocks 10 are arranged equidistantly in a ring shape, and the plurality of limit blocks 10 are arranged in an arc shape at one end close to each other. A plurality of slide grooves are opened at the outer end of the mounting ring 1, and a slider matching the slide groove is fixedly connected to the inner end of the limit block 10, and the slider is slidably connected to the slide groove. A spring 11 is arranged in the slide groove, and the two ends of the spring 11 are respectively fixedly connected to the inner wall of the slide groove and the slider.

[0046] When the user puts the mounting ring 1 on the outer end of the extruder die head, the mounting ring 1 is tightened by tightening the screw 3. During this process, the inner ends of the multiple limit blocks 10 are always in contact with the outer end of the extruder die head, and as the mounting ring 1 is tightened, the limit blocks 10 will slide in the slide groove through the slider, causing compression on the spring 11. The elastic action of the spring 11 will make the limit blocks 10 tightly abut against the outer surface of the extruder die head, so that the multiple limit blocks 10 are surrounded on both sides of the annular filling bag 6. Through the setting of the limit blocks 10, the annular filling bag 6 can be limited, so that the annular filling bag 6 does not extend to the outside of the mounting ring 1 while expanding, thereby reducing the expandable range of the annular filling bag 6, so that the expanded annular filling bag 6 can be more compactly squeezed between the thermal conductive silicone ring 4 and the extruder die head, thereby further reducing the existence of the gap.

[0047] Working principle:

[0048] The user sets the installation ring 1 on the outer end of the extruder die head, and tightens the installation ring 1 by tightening the screw 3 to fix it on the outer end of the extruder die head. The outer end of the installation ring 1 is equipped with a heating unit, and both ends of the oil pipe 5 extend from the position of the reserved port 2 and are connected to the heating unit to form an oil temperature conduction cycle. As the oil pipe 5 introduces hot oil, the thermally conductive silicone ring 4 begins to conduct heat, and the annular expansion block 7 absorbs the heat of the thermally conductive silicone ring 4 and expands inside the annular filling capsule 6, thereby promoting the annular filling capsule 6 to expand, so that the surface of the annular filling capsule 6 fills the gap between the thermally conductive silicone ring 4 and the extruder die head, so that the heat of the oil pipe 5 can be successively conducted to the extruder die head through the thermally conductive silicone ring 4, the annular expansion block 7 and the annular filling capsule 6, reducing the gap between the thermally conductive silicone ring 4 and the surface of the extruder die head. The gap effectively improves the heat conduction speed. The arrangement of the first heat conducting wire 8 and the second heat conducting wire 9 enables the heat in the heat conductive silicone ring 4 to be more quickly conducted to the inside of the annular filling bag 6 and the annular expansion block 7 at the same time. At the same time, when the user sets the mounting ring 1 on the outer end of the extruder die head, the inner ends of the plurality of limit blocks 10 are always in contact with the outer end of the extruder die head. As the mounting ring 1 is tightened, the limit blocks 10 will slide in the slide groove through the slider, causing compression on the spring 11. The elastic action of the spring 11 will make the limit blocks 10 tightly abut against the outer surface of the extruder die head, so that the plurality of limit blocks 10 are surrounded on both sides of the annular filling bag 6, which plays a limiting role on the annular filling bag 6 and reduces the expandable range of the annular filling bag 6, so that the expanded annular filling bag 6 can be more compactly squeezed between the heat conductive silicone ring 4 and the extruder die head.

[0049] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
