A liquid pump extracts resin, which is then sprayed from a nozzle through an annular pipe. As the conductive powder falls, it passes through the resin spray area formed by the annular pipe nozzle. This ensures that the conductive powder is evenly wetted by the sprayed resin before entering the mixing device. This avoids the phenomenon of dry powder sandwiching or hard agglomerates caused by the rapid coating of the outer resin and the retention of dry powder inside, which is common in traditional one-time feeding methods when a large amount of powder is instantly fed into high-viscosity resin. In the premixing stage, the material has initially formed a uniform slurry, reducing the dispersion difficulty and agglomeration resistance in the subsequent mixing process of the mixing device, shortening the overall dispersion time, and reducing the operating load of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric heating film mixing, specifically an electric heating film mixing device. Background Technology
[0002] An electrothermal film is a semi-transparent polyester film that generates heat when electricity is applied. It consists of conductive ink, metal current-carrying strips, a polyester film substrate, and various protective layers. The electrothermal film converts electrical energy directly into heat energy by applying voltage to the conductive ink layer and utilizing the resistance characteristics of the conductive material.
[0003] Traditional methods involve directly pouring large amounts of conductive powder into high-viscosity resin, which can easily cause the outer layer of resin to quickly coat the powder and form dense clumps. Meanwhile, the inner powder cannot effectively wet and contact the resin, resulting in hard-to-disperse dry powder sandwiches or hard agglomerates. This leads to prolonged mixing time and increased equipment operating burden. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses an electrothermal film mixing device. (Refer to...) Figure 1 , Figure 2 and Figure 3 An electric heating film mixing device includes a mixing device body 1, a liquid inlet pipe 3 fixedly connected to the top of the mixing device body 1, a feed pipe 4 fixedly connected to the top of the mixing device body 1, and a premixing mechanism 2 provided on the inner wall of the feed pipe 4.
[0024] The premixing mechanism 2 includes a storage tank 201, which is fixedly connected to the surface of the feed pipe 4. A pump 202 is fixedly connected to the top of the storage tank 201. The inlet end of the pump 202 is fixedly connected to a first connecting pipe 203, one end of which extends through to the inner wall of the storage tank 201. The outlet end of the pump 202 is fixedly connected to a second connecting pipe 204. An annular pipe 205 is fixedly connected to the inner wall of the feed pipe 4. One end of the second connecting pipe 204 extends through to the inner wall of the feed pipe 4 and is fixedly connected to the surface of the annular pipe 205. A nozzle 206 is fixedly connected to the surface of the annular pipe 205. A diverter plate 207 is rotatably connected to the inner wall of the feed pipe 4. The surface of 07 contacts the inner wall of the feed pipe 4. One end of the diverter 207 penetrates the inner wall of the feed pipe 4 and extends to the outside. The surface of the feed pipe 4 is fixedly connected to the first motor 208. The output end of the first motor 208 is fixedly connected to one end of the diverter 207. By setting the premixing mechanism 2, the first motor 208 controls the rotation of the diverter 207 to control the amount of conductive powder fed. Then, the resin is extracted by the liquid pump 202 and sprayed out from the nozzle 206 through the annular pipe 205. During the falling process, the conductive powder will pass through the resin spraying area formed by the annular pipe 205 and the nozzle 206, so that the conductive powder is already fused with the uniformly sprayed resin before entering the mixing device body 1.
[0025] Reference Figure 2 and Figure 4 A material distribution plate 8 is fixedly connected to the inner wall of the feed pipe 4, and a material distribution column 10 is rotatably connected to the inner cavity of the feed pipe 4. Both the material distribution plate 8 and the material distribution column 10 have protrusions fixedly connected to their surfaces. The material distribution plate 8 and the material distribution column 10 work together. By setting up the material distribution plate 8 and the material distribution column 10, the shear friction force formed between the rotating material distribution column 10 and the fixed material distribution plate 8 is used to break up the conductive powder agglomerates that exist during the falling process. At the same time, the resin sprayed from the nozzle 206 enters the area between the material distribution plate 8 and the material distribution column 10. Under the action of the friction force generated by the rotation of the material distribution column 10, the resin is broken up and comes into full contact with the dispersed conductive powder, mixing the conductive powder with the resin.
[0026] Reference Figure 4 The inner cavity of the feed pipe 4 is provided with a protective box 9. Positioning rods 11 are fixedly connected to both sides of the protective box 9. Both ends of the positioning rods 11 are fixedly connected to the inner wall of the feed pipe 4. The protective box 9 is fixedly connected to the inner cavity of the feed pipe 4 through the two positioning rods 11. The protective box 9 and the positioning rods 11 can provide physical protection for the transmission components, prevent the conductive powder after being fused with the resin from obstructing the transmission components during the falling process, and ensure the smoothness of the falling of the conductive powder after being fused with the resin inside the feed pipe 4.
[0027] Reference Figure 4A connecting rod 13 is fixedly connected to the bottom of the material distribution column 10. The connecting rod 13 is rotatably connected to the inner wall of the protective box 9. The bottom of the material distribution column 10 contacts the top of the protective box 9. The connecting rod 13 is used to support and position the material distribution column 10, ensuring the stability of the connection between the material distribution column 10 and the protective box 9, ensuring the stability of the material distribution column 10 when rotating, and preventing the material distribution column 10 from shaking.
[0028] Reference Figure 4 A second motor 7 is fixedly connected to the surface of the feed pipe 4. A transmission rod 12 is fixedly connected to the output end of the second motor 7. One end of the transmission rod 12 passes through the inner wall of the feed pipe 4, the protective box 9, and a positioning rod 11. Through the arrangement of the second motor 7 and the transmission rod 12, the second motor 7 provides driving force to drive the transmission rod 12 to rotate, thereby transmitting power and ensuring the stability of power transmission.
[0029] Reference Figure 4 One end of the transmission rod 12 is fixedly connected to a first bevel gear 14, and the surface of the connecting rod 13 is fixedly connected to a second bevel gear 15. The surfaces of the first bevel gear 14 and the second bevel gear 15 mesh with each other. Through the arrangement of the first bevel gear 14 and the second bevel gear 15, the power transmitted by the transmission rod 12 can be converted from the horizontal direction to the vertical direction, which can maintain stable torque transmission and ensure that the material distribution column 10 operates continuously and stably.
[0030] Reference Figure 2 and Figure 4 The inner wall of the feed pipe 4 is fixedly connected with two sealing rings 5. The inner walls of the two sealing rings 5 are in contact with the surfaces of the transmission rod 12 and the diverter plate 207, respectively. The top of the storage tank 201 is fixedly connected to the liquid supply pipe 6. By setting the sealing rings 5, the gap between the transmission rod 12 and the diverter plate 207 and the inner wall of the feed pipe 4 can be filled to prevent dust from entering the feed pipe 4 through the gap and ensure the cleanliness of the conductive powder.
[0031] Working principle: The mixing device body 1 injects resin into the mixing tank through the inlet pipe 3, then adds conductive powder. A motor drives the agitator to rotate, mixing the resin and conductive powder evenly. This is existing technology and will not be elaborated further. The user first injects resin into the mixing device body 1 through the feed pipe 4, then starts the first motor 208 via an external control switch. The first motor 208 is powered by an external power supply. The output of the first motor 208 drives the distribution plate 207 to rotate. By controlling the rotation angle of the distribution plate 207, the opening and closing degree of the distribution plate 207 within the feed pipe 4 channel is adjusted, thus controlling the mixing of the conductive powder. The material flow rate and feed rate are controlled. Simultaneously, the user starts the liquid pump 202 via an external control switch. The liquid pump 202 is powered by an external power source and draws resin from the storage tank 201 through the first connecting pipe 203. The drawn resin enters the inlet of the liquid pump 202 and then flows from the outlet into the second connecting pipe 204. From there, it enters the annular pipe 205 and is sprayed out through the nozzle 206. The sprayed resin comes into contact with falling conductive powder. As the resin and conductive powder fall, they enter between the distribution plate 8 and the distribution column 10. The user then starts the second motor 7, which is powered by an external power source. Power is supplied, and the output end of the second motor 7 drives the transmission rod 12 to rotate. The rotation of the transmission rod 12 drives the first bevel gear 14 to rotate synchronously. The first bevel gear 14 meshes with the second bevel gear 15, and the rotation of the first bevel gear 14 drives the rotation of the second bevel gear 15. The rotation of the second bevel gear 15 drives the connected connecting rod 13 to rotate synchronously. The rotation of the connecting rod 13 drives the material distribution column 10 to rotate synchronously. The shear friction formed between the rotating material distribution column 10 and the fixed material distribution plate 8 is used to break up the clumps of conductive powder during the falling process, so that the conductive powder is evenly distributed. At the same time, it is arranged around the plate. The resin sprayed from the nozzle 206 simultaneously enters the shear zone. When the resin enters the gap, it is subjected to the centrifugal force generated by the rotation of the distribution column 10, and is thrown to all sides and spread into a thin layer, uniformly covering the surface of the distribution column 10. During this process, the conductive powder that has just been dispersed will come into contact with the flowing resin. Under the action of friction, the resin will fuse with the conductive powder to form a uniform premixed slurry, preventing the conductive powder from re-agglomerating after leaving the shear zone. The premixed slurry will be discharged from the bottom of the distribution column 10 and the distribution plate 8, and then enter the mixing device body 1, where it will fuse with the resin in the mixing device body 1 through the agitator.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
