Description

Technical Field

[0001] This utility model relates to the technical field of insulating sheet production equipment, and in particular to a mixing tank for a double planetary mixer. Background Technology

[0002] Insulating sheets are widely used in electronic products due to their excellent electrical insulation, mechanical properties, and heat resistance. In the consumer electronics industry, they are used between batteries and circuit boards, and between chips and heat dissipation components, serving as insulation and buffering mechanisms. Currently, some high-performance insulating sheets are produced using a casting process. This process involves mixing materials and then casting the mixture into sheets of the desired thickness using a casting machine. The mixing process requires a double planetary mixer.

[0003] Existing planetary mixers typically use a discharge port on the mixing drum. Since the discharge port usually uses a ball valve or butterfly valve as the closing valve, although this commonly used valve can complete the opening and closing work, there are inevitably dead zones between the valve and the drum body. When the material gets stuck in the dead zone, the mixing blades of the planetary mixer will have difficulty mixing this part of the material, resulting in insufficient mixing of the output material. Therefore, there is a need for a mixing drum that can reduce the dead zone area to improve the mixing efficiency of the material. Utility Model Content

[0004] The purpose of this invention is to provide a mixing tank for a double planetary mixer, which aims to solve the problem of uneven material mixing caused by dead zones in existing mixing tanks.

[0005] To achieve the above objectives, this utility model provides a mixing tank for a double planetary mixer, including a mixing tank body with a discharge port on the mixing tank body. A valve assembly is provided at the discharge port, and the valve assembly includes a discharge pipe, an adapter, a telescopic drive mechanism, and a sealing plate. The adapter is installed in the discharge port and is detachably connected to the discharge pipe. The telescopic drive mechanism is installed in the discharge pipe and is used to drive the sealing plate to move closer to or away from the discharge port. One side of the sealing plate fits against the inner wall of the mixing tank body, and the diameter of the sealing plate is smaller than the diameter of the discharge pipe.

[0006] Furthermore, the telescopic drive mechanism includes a sleeve, a sliding rod, and an adjusting gear. A mounting seat is provided inside the discharge pipe for installing the sleeve. The sliding rod is installed in the sleeve and has an adjusting rack that meshes with the adjusting gear. The sliding rod is fixedly connected to the sealing plate.

[0007] Furthermore, an adjusting handle is also provided on the discharge pipe, and the adjusting handle is connected to the adjusting gear.

[0008] Furthermore, the main body of the mixing tank includes an inner cylinder and an outer cylinder connected together, with a cavity provided between the inner cylinder and the outer cylinder. The discharge port is installed on the inner cylinder and passes through the outer cylinder.

[0009] Furthermore, the bottom of the discharge port is lower than the bottom of the inner cylinder.

[0010] Furthermore, the cavity is filled with heat-conducting oil, and a surrounding heating wire is installed inside the cavity. The surrounding heating wire is immersed in the heat-conducting oil, and a heating wire conductive connector is provided at both ends of the surrounding heating wire.

[0011] Furthermore, the surrounding heating wire includes a connected sidewall heating wire and a bottom heating wire, with the bottom heating wire installed at the bottom of the inner cylinder and the sidewall heating wire installed on the sidewall of the inner cylinder.

[0012] Furthermore, an isolation layer is provided in the cavity, and the heating wire and heat-conducting oil are both placed between the isolation layer and the inner cylinder.

[0013] Furthermore, a pulley system is provided at the bottom of the outer cylinder, and a handrail is provided on the side wall of the outer cylinder.

[0014] The mixing drum for a double planetary mixer provided by this utility model, compared with the prior art, can block the discharge port when mixing is required, making the inner cylinder a single unit, avoiding dead corners at the discharge port that affect mixing efficiency. When it is necessary to discharge materials, the user can rotate the adjustment handle to retract the sealing plate into the discharge pipe, allowing the discharge port to open and facilitating the flow of materials.

[0029] The present invention will be described in detail below with reference to specific embodiments.

[0030] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0031] like Figures 1 to 10 As shown, this utility model provides a mixing tank for a double planetary mixer, including a mixing tank body 1. The mixing tank body 1 is provided with a discharge port 12. A valve assembly 2 is provided at the discharge port 12. The valve assembly 2 includes a discharge pipe 21, an adapter 20, a telescopic drive mechanism, and a sealing plate 24. The adapter 20 is installed in the discharge port 12 and is detachably connected to the discharge pipe 21. The telescopic drive mechanism is installed in the discharge pipe 21 and is used to drive the sealing plate 24 to move closer to or away from the discharge port 12. One side of the sealing plate 24 fits against the inner wall of the mixing tank body 1, and the diameter of the sealing plate 24 is smaller than the diameter of the discharge pipe 21.

[0032] With the above design scheme, under the drive of the telescopic drive mechanism, the sealing plate 24 will fit tightly against the inner wall of the inner cylinder 10, blocking the discharge pipe 21, reducing the dead area of ​​the mixing tank body 1, and ensuring that the material can be mixed evenly. When it is necessary to release the mixed material, the telescopic drive mechanism will bring the sealing plate 24 into the discharge pipe 21. Since the diameter of the sealing plate 24 is smaller than that of the discharge pipe 21, the sealing plate 24 entering the discharge pipe 21 will not completely block the discharge pipe 21, and the material can flow out from the gap between the sealing plate 24 and the discharge pipe 21.

[0033] In this embodiment, the telescopic drive mechanism includes a sleeve 23, a sliding rod 25, and an adjusting gear 27. A mounting seat 22 is provided inside the discharge pipe 21 for mounting the sleeve 23. The sliding rod 25 is installed in the sleeve 23 and an adjusting rack 26 is provided on the sliding rod 25. The adjusting rack 26 meshes with the adjusting gear 27. The sliding rod 25 is fixedly connected to the sealing plate 24.

[0034] In this embodiment, an adjusting handle 28 is also provided on the discharge pipe 21, and the adjusting handle 28 is connected to the adjusting gear 27.

[0035] With the above design, when the sealing plate 24 needs to be adjusted, the user can rotate the adjusting handle 28 to make the adjusting gear 27 rotate. The rotating adjusting gear 27 drives the sliding rod 25 to move in the sleeve 23 through the meshing adjusting rack 26, thereby making the sealing plate 24 closer to or further away from the discharge port 12.

[0036] In this embodiment, the discharge port 12 and the adapter 20, and the adapter 20 and the discharge pipe 21 are all connected by threads. When cleaning the discharge pipe 21 is required, the user can remove the discharge pipe 21 separately. Under the action of the mounting base 22, the telescopic drive mechanism will be disassembled together with the discharge pipe 21, and the sealing plate 24 connected to the telescopic drive mechanism will also be removed from the mixing tank body 1, facilitating the cleaning of the discharge pipe 21. In this embodiment, the mounting base 22 is connected to the telescopic drive mechanism by screws and bolts. The user can further remove the telescopic drive mechanism from the discharge pipe 21 by loosening the screws and bolts and removing the adjusting handle 28, facilitating further cleaning of the discharge pipe 21 and the telescopic drive mechanism.

[0037] In this embodiment, the mixing tank body 1 includes an inner cylinder 10 and an outer cylinder 11 connected to each other. A cavity is provided between the inner cylinder 10 and the outer cylinder 11. The discharge port 12 is installed on the inner cylinder 10 and passes through the outer cylinder 11.

[0038] In this embodiment, the bottom of the discharge port 12 is lower than the bottom of the inner cylinder 10. Since the bottom of the discharge port 12 is lower, when it is necessary to block the discharge port 12, the sealing plate 24 will press against the bottom of the inner cylinder 10 to prevent the sealing plate 24 from extending too far into the inner cylinder 10 and affecting the mixing efficiency.

[0039] In this embodiment, the cavity is filled with heat-conducting oil, and a surrounding heating wire 13 is also installed in the cavity. The surrounding heating wire 13 is immersed in the heat-conducting oil, and a heating wire conductive connector 132 is provided at both ends of the surrounding heating wire 13.

[0040] In this embodiment, the surrounding heating wire 13 includes a side wall heating wire 130 and a bottom heating wire 131 that are connected to each other. The bottom heating wire 131 is installed at the bottom of the inner cylinder 10, and the side wall heating wire 130 is installed on the side wall of the inner cylinder 10.

[0041] Through the above design scheme, in some stirring scenarios, the heating wire 13 heats up to raise the temperature of the heat transfer oil. The heated heat transfer oil can evenly raise the temperature of the side walls of the inner cylinder 10, thereby raising the temperature of the material inside the inner cylinder 10 and improving the stirring efficiency. The side wall heating wire 130 and the bottom heating wire 131 can exchange heat with the heat transfer oil on the side and bottom of the inner cylinder 10 respectively, thereby increasing the heat exchange area and improving the heat exchange efficiency.

[0042] In this embodiment, an isolation layer 14 is provided in the cavity. The isolation layer 14 can provide heat insulation. The heating wire 13 and the heat transfer oil are both provided between the isolation layer 14 and the inner cylinder 10. The isolation layer 14 can prevent heat from being transferred to the outer cylinder 11 and burning the user. At the same time, the isolation layer 14 can also prevent the heat transfer oil from leaking.

[0043] In this embodiment, a pulley group 16 is provided at the bottom of the outer cylinder 11, and a handrail 15 is provided on the side wall of the outer cylinder 11.

[0044] The mixing drum for a double planetary mixer provided by this utility model, compared with the prior art, can block the discharge port 12 when mixing is required, making the inner cylinder 10 a single unit, avoiding the dead corner at the discharge port 12 from affecting the mixing efficiency. When it is necessary to discharge the material, the user can rotate the adjusting handle 28 to retract the sealing plate 24 into the discharge pipe 21, allowing the discharge port 12 to open and facilitate the material to flow out.

[0045] Where there is no conflict, the above embodiments and features can be combined with each other.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
