Description

Technical Field

[0001] This utility model relates to the field of mixing machines, specifically a mixing machine for precise proportioning of insulating raw material masterbatch. Background Technology

[0002] Insulating masterbatch is made from carefully selected imported insulating carbon black, combined with special PA raw materials and chemical additives, through high-energy mixing and refining. It is mainly used for electrical products, and electrical casings need to withstand high voltage breakdown, have strong applicability, and withstand high temperatures. It also has a certain strengthening and wear resistance effect on the product. It is commonly processed by injection molding and extrusion processes. During processing, the masterbatch and raw materials are put into a mixer in proportion and mixed evenly. The mixer is used to mix the raw materials. During use, various raw materials are put into the mixer in a certain proportion and mixed. Existing mixers cannot measure the amount of raw materials added. It is necessary to weigh the raw materials with weighing equipment first and record the weight manually before putting them into the mixer for mixing, which affects the accuracy of the proportioning.

The metering screw 42 is rotatably installed inside the feeding pipe 43. The feeding pipe 43 is connected to a temporary storage cylinder 44. A weighing sensor 45 is installed on one side of the temporary storage cylinder 44. A solenoid valve 46 is installed at the bottom of the temporary storage cylinder 44. A display 47 is provided on the surface of the temporary storage cylinder 44.

[0031] In practical use: A servo motor 41 is installed on the top of the mixing tank 3. After the servo motor 41 rotates, it drives the metering screw 42 to rotate. The metering screw 42 is installed in the feeding pipe 43. The servo motor 41 controls the metering screw 42 to feed the material. The color masterbatch in the mixing tank 3 falls into the temporary storage cylinder 44. The feeding is weighed by the weighing sensor 45 installed on the surface of the temporary storage cylinder 44. The weighing result is displayed on the display 47, which makes it easy for personnel to observe the amount of material to be added according to the ratio. After the required amount of material is met, the solenoid valve 46 opens to feed the material. The feeding is precisely controlled by the screw and the material is fed after automatic weighing, which replaces the manual weighing and feeding method, so as to complete the accurate ratio of feeding.

[0032] Please see Figure 1 , Figure 3 The mixing assembly 5 includes a rotary motor 51 mounted on the top of the cover plate 101. A reducer 52 is mounted on the output end of the rotary motor 51. A transmission rod 53 is fixedly mounted on the output end of the reducer 52. The transmission rod 53 extends into the mixing tank 1, and stirring blades 54 are mounted on the surface of the transmission rod 53.

[0033] In practical use: When the rotating motor 51 rotates, the speed reduction and torque increase of the reducer 52 drive the transmission rod 53 to rotate inside the mixing tank 1. The transmission rod 53 fully mixes and stirs the added masterbatch through the stirring blades 54 installed on the surface, which facilitates subsequent processing.

[0034] Please see Figure 3 A U-shaped rod 6 is installed at the bottom of the transmission rod 53, and several scrapers 7 are fixedly installed on the surface of the U-shaped rod 6. The scrapers 7 are in contact with the inner wall of the mixing tank 1.

[0035] In practical use: A U-shaped rod 6 is installed at the bottom of the transmission rod 53. The rotation of the U-shaped rod 6 drives the scraper 7 on the surface to scrape and clean the inner wall of the mixing tank 1, so as to prevent the material from adhering to the inner wall of the mixing tank 1.

[0036] Please see Figure 1 , Figure 3 The cover plate 101 has feeding ports 8 on both sides of its surface. A screw feeder 9 is installed at the bottom of the temporary storage cylinder 44. The discharge end of the screw feeder 9 extends to the top of the feeding port 8.

[0037] In practical use: feeding ports 8 are provided on both sides of the surface of the cover plate 101. The screw feeder 9 installed at the bottom of the temporary storage cylinder 44 conveys the weighed material to the feeding port 8, thereby adding the material into the mixing tank 1 for mixing.

[0038] Please refer to Figure 4. A vacuum feeder 10 is installed on the top side of the mixing tank 3. A conveying pipe 11 is connected to the bottom of the vacuum feeder 10. One end of the conveying pipe 11 is connected to a hopper 12.

[0039] In practical use: After the vacuum feeder 10 installed on one side of the top of the mixing tank 3 starts working, it conveys the color masterbatch in the hopper 12 to the mixing tank 3 through the conveying pipe 11, which facilitates the replenishment of the mixing tank 3.

[0040] Please see Figure 1 A discharge pipe 13 is installed at the bottom of the mixing tank 1.

[0041] In practical use: After mixing is completed, the mixture is discharged outward through the discharge pipe 13 at the bottom of the mixing tank 1.

[0042] Please see Figure 1 The surface of the support leg 2 is equipped with a control panel. The servo motor 41, the load cell 45, the solenoid valve 46, the display 47, the rotary motor 51, the screw feeder 9 and the vacuum feeder 10 are all electrically connected to the control panel. The control panel is electrically connected to an external power supply.

[0043] In practical use: When the control panel is connected to the external power supply, the servo motor 41, weighing sensor 45, solenoid valve 46, display 47, rotary motor 51, screw feeder 9 and vacuum feeder 10 are powered on and controlled to run. When the control panel is disconnected from the external power supply, the equipment stops running.

[0044] A servo motor 41 is installed on the top of the mixing tank 3. After the servo motor 41 rotates, it drives the metering screw 42 to rotate. The metering screw 42 is installed in the feeding pipe 43. The servo motor 41 controls the metering screw 42 to feed the material. The color masterbatch in the mixing tank 3 falls into the storage tank 44. The feeding is weighed by the weighing sensor 45 installed on the surface of the storage tank 44. The weighing result is displayed on the display 47, which makes it easy for personnel to observe the amount to be added according to the ratio. After the required amount of the ratio is met, the solenoid valve 46 opens to feed the material. The feeding is precisely controlled by the screw and automatically weighed before feeding, which replaces the manual weighing and feeding method, so as to complete the accurate feeding ratio. When the color masterbatch is put into the mixing tank 1 according to the ratio, the rotating motor 51 is controlled to rotate. The speed reduction and torque increase of the reducer 52 drives the transmission rod 53 to rotate inside the mixing tank 1. The transmission rod 53 mixes and stirs the added color masterbatch through the stirring blade 54 installed on its surface, which facilitates subsequent processing.
