Description

Technical Field

[0001] This utility model relates to the field of thermoplastic elastomer raw material mixing technology, and in particular to a fluorosilicone dynamic vulcanization thermoplastic elastomer raw material mixing device. Background Technology

[0002] Fluorosilicone dynamically vulcanized thermoplastic elastomers, as a high-performance material, combine the chemical resistance and high-temperature resistance of fluororubber with the easy processability of thermoplastics, making them widely used in many high-end fields such as aerospace, automotive manufacturing, and electronics. In their production process, the raw material mixing stage is crucial, as the mixing effect directly determines the performance and quality of the final product.

[0003] A mixing device for processing thermoplastic elastomer raw materials, as disclosed in publication number CN220162899U, includes a base, a screw, a mixing chamber, a mixing assembly, a drive component, a scraper, and a filter screen. A support frame is fixedly connected to the base, and the screw is threadedly connected to the support frame. A clamping block is fixedly connected to the inner end of the screw, and the clamping block faces the side of the mixing chamber. Two bases are used, with the lower sides of the mixing chamber connected to the two bases respectively. The mixing chamber has an internal cavity for holding the thermoplastic elastomer raw material. A feed pipe is connected to one side of the upper end of the mixing chamber, and the feed pipe communicates with the cavity. The mixing assembly is connected to the upper part of the mixing chamber. After mixing the material, the device discharges the material through the discharge pipe. However, because the material is stirred during heating, it becomes sticky and easily adheres to the inner wall of the discharge pipe. The discharge pipe opening is small, making cleaning inconvenient and hindering rapid material discharge, resulting in low efficiency.

[0004] Therefore, it is necessary to design a fluorosilicone dynamic vulcanized thermoplastic elastomer raw material mixing device that can automatically flip the heating tank after the rotating cover is opened, so as to facilitate quick material discharge and easy cleaning. Utility Model Content

[0005] To overcome the shortcomings of material mixing and heating processes, such as the material's stickiness causing it to adhere to the inner wall of the discharge pipe, the small size of the discharge pipe opening making cleaning inconvenient, and the inconvenience of quickly discharging the material, resulting in low efficiency, this utility model provides a fluorosilicone dynamic vulcanized thermoplastic elastomer raw material mixing device that can automatically flip the heating tank after opening the rotating cover, facilitating quick material discharge and easy cleaning.

[0006] The technical solution is as follows: A mixing device for fluorosilicone dynamically vulcanized thermoplastic elastomer raw materials, comprising a support frame, an insulated barrel, a first motor, a bidirectional lead screw, a sealing cover, a second motor, a stirring frame, a slide rail, an opening and closing assembly, and a tilting assembly. The insulated barrel is connected to the upper side of the middle of the support frame, and the first motor is connected to the upper right side of the support frame. The first motor and the processor are electrically connected through a control module. The bidirectional lead screw is connected to the output shaft of the first motor and is rotatably connected to the support frame. The sealing cover is threadedly connected to the upper part of the bidirectional lead screw and is slidably connected to the support frame. The second motor is connected to the middle of the sealing cover and is electrically connected to the processor through a control module. The stirring frame is connected to the output shaft of the second motor. A slide rail is connected to the inner rear side of the insulated barrel. The right side of the support frame is provided with an opening and closing assembly that can open the bottom of the insulated barrel while raising the stirring frame. The support frame is provided with a tilting assembly that can tilt and quickly pour materials while descending.

[0007] Furthermore, a feed pipe is provided on the upper rear side of the sealing cap.

[0008] Furthermore, the opening and closing assembly includes a rotating cover, a pressing block, a torsion spring, a pressure rod, and a roller. The rotating cover is rotatably connected to the right middle part of the support frame, and the pressing block is connected to the rear right side of the rotating cover. A torsion spring is connected between the pressing block and the support frame. The pressure rod is connected to the rear side of the sealing cover, and a roller is rotatably connected to the lower part of the pressure rod. The roller contacts the pressing block.

[0009] Furthermore, a sealing gasket is provided on the outside of the rotating cover.

[0010] Furthermore, the pressing block has a folded structure.

[0011] Furthermore, it also includes a flipping assembly, which includes a sliding frame, a heating barrel, a gear, and a rack. The lower part of the bidirectional lead screw is threadedly connected to the sliding frame, which is slidably connected to the support frame. The left side of the sliding frame is rotatably connected to the heating barrel, which is slidably engaged with the slide rail. The front side of the heating barrel is connected to a gear, and the front part of the support frame is connected to a rack, which meshes with the gear.

[0012] The beneficial effects are as follows: 1. This utility model uses a torsion spring to drive the pressing block to rotate, so that the rotating cover can be opened. When the sliding frame continues to move downward, the gear and rack will mesh with each other and drive the heating barrel to rotate, so that the material inside the heating barrel can be poured out. This achieves the effect of automatically flipping the heating barrel after the rotating cover is opened, which is convenient for quickly pouring out the material and is easy to clean.

[0013] 2. This utility model starts the first motor, which drives the bidirectional lead screw to rotate, causing the sealing cover and the sliding frame to move under the action of the screw thread. This causes the sealing cover and the sliding frame to move away from each other. As the sealing cover moves upward, it will drive the stirring frame to move upward, so that the stirring frame no longer contacts the inside of the heating tank. This achieves the effect of automatically lifting the stirring frame, making it easier to clean the stirring frame. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] A mixing device for fluorosilicone dynamically vulcanized thermoplastic elastomer raw materials, such as Figures 1-5As shown, the device includes a support frame 1, an insulated container 2, a first motor 3, a bidirectional lead screw 4, a sealing cover 5, a second motor 6, a stirring rack 7, a slide rail 8, an opening and closing assembly, and a tilting assembly. The insulated container 2 is connected to the upper middle part of the support frame 1, and the first motor 3 is connected to the upper right side of the support frame 1. The first motor 3 and the processor are electrically connected through a control module. The bidirectional lead screw 4 is connected to the output shaft of the first motor 3 and is rotatably connected to the support frame 1. The sealing cover 5 is threadedly connected to the upper part of the bidirectional lead screw 4. A feed pipe is provided on the upper rear part of the sealing cover 5 for easy feeding. The sealing cover 5 is slidably connected to the support frame 1. The second motor 6 is connected to the middle of the sealing cover 5 and is electrically connected to the processor through a control module. The stirring rack 7 is connected to the output shaft of the second motor 6. The slide rail 8 is connected to the inner rear part of the insulated container 2. The opening and closing assembly is provided on the right side of the support frame 1, and the tilting assembly is provided on the support frame 1.

[0023] like Figures 2-4 As shown, the opening and closing assembly includes a rotating cover 9, a pressing block 10, a torsion spring 11, a pressure rod 12, and a roller 13. The rotating cover 9 is rotatably connected to the right middle part of the support frame 1. A sealing gasket is provided on the outside of the rotating cover 9 to facilitate its fit with the heat preservation bucket 2. The pressing block 10 is connected to the rear right side of the rotating cover 9. The pressing block 10 has a folded structure to facilitate rotation by being squeezed. A torsion spring 11 is connected between the pressing block 10 and the support frame 1. The pressure rod 12 is connected to the rear side of the sealing cover 5. The roller 13 is rotatably connected to the lower part of the pressure rod 12 and contacts the pressing block 10.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, it also includes a flipping assembly, which includes a sliding frame 14, a heating barrel 15, a gear 16, and a rack 17. The lower part of the bidirectional lead screw 4 is threadedly connected to the sliding frame 14, and the sliding frame 14 is slidably connected to the support frame 1. The left side of the sliding frame 14 is rotatably connected to the heating barrel 15, and the heating barrel 15 is slidably engaged with the slide rail 8. The front side of the heating barrel 15 is connected to the gear 16, and the front part of the support frame 1 is connected to the rack 17, with the rack 17 and the gear 16 meshing with each other.

[0025] At this time, the torsion spring 11 is in a deformed state. When using this device, first place the support frame 1 in the mixing area of ​​the fluorosilicone dynamic vulcanized thermoplastic elastomer raw material, then add the thermoplastic elastomer raw material and the material to be mixed into the heating tank 15, and heat it through the heating tank 15. Then, the processor starts the second motor 6 through the control module, which drives the stirring frame 7 to rotate. The stirring frame 7 mixes and stirs the thermoplastic elastomer raw material. After the stirring is completed, start the first motor 3, which drives the bidirectional lead screw 4 to rotate, so that the sealing cover 5 and the sliding frame 14 move under the action of the thread, so that the sealing cover 5 and the sliding frame 14 move away from each other, and the sealing cover 5 no longer contacts the heat preservation tank 2. During the upward movement of the sealing cover 5, it will drive the stirring frame 7 to move upward, so that the stirring frame 7 no longer contacts the heating tank 15, thereby automatically lifting the stirring frame 7, which is convenient for cleaning the stirring frame 7.

[0026] As the sealing cover 5 moves upward, it drives the pressure rod 12 to move upward, causing the roller 13 to move upward. The torsion spring 11 gradually returns to its original state, driving the pressing block 10 to rotate, causing the rotating cover 9 to rotate and open. When the sliding frame 14 moves downward, it drives the heating barrel 15 to move downward along the slide rail 8, causing the heating barrel 15 to disengage from the slide rail 8. As the sliding frame 14 continues to move downward, the gear 16 and the rack 17 will mesh with each other, driving the heating barrel 15 to rotate, causing the material inside the heating barrel 15 to pour out. Thus, the heating barrel 15 can be automatically flipped after the rotating cover 9 is opened, which is convenient for quickly pouring out the material and for easy cleaning.
