Description

Technical Field

[0001] This utility model belongs to the field of plastic product processing technology, and specifically relates to a two-component mixing device with color masterbatch metering. Background Technology

[0002] In recent years, beverage packaging, frozen food packaging, reheatable food packaging, and fast food packaging have become increasingly ubiquitous in daily life. These products have brought great convenience to people's lives, which has also driven the rapid development of the plastic film industry. Currently, colored plastic film is one of the fastest-growing categories of plastic products in my country.

[0003] In the production of colored films, special masterbatch raw materials need to be added. In the existing technology, masterbatch can be added to the extruder through a masterbatch machine.

[0004] For example, patent application number CN201921298835.4 discloses a weighing-type color masterbatch mixer, including a main hopper and a base. The discharge port at the bottom of the main hopper is connected to the base. It also includes a feeding mechanism and a storage hopper. The feeding mechanism includes a conveying cylinder inserted into the base. The conveying cylinder has a discharge hole. A screw is installed inside the conveying cylinder. A motor is installed on the conveying cylinder. One end of the screw is connected to the motor through a coupling. The other end of the screw is inclined upward and extends through the conveying cylinder into the base. The storage hopper includes a support plate and a storage hopper body. The support plate is installed on the conveying cylinder. The storage hopper body is connected to the support plate through a weighing sensor. The bottom of the storage hopper body has a discharge port I connected to the conveying cylinder. The top of the storage hopper body has a first opening. A cover plate is rotatably installed on the support plate to cover the first opening. It also includes a support mechanism to support the cover plate. A stirring device is installed inside the base. A stirring motor controlling the stirring device is installed on the base.

[0005] For example, patent application number CN202110268126.7 discloses a weighing-type color masterbatch machine, including a base, the base and a control device. A main material barrel is fixedly installed on the upper part of the base, a feeding cylinder is fixedly installed on one side of the base, a shaft is rotatably installed inside the feeding cylinder, a spiral blade is fixedly installed on the outside of the shaft, a stepper motor is fixedly installed at one end of the feeding cylinder, a color masterbatch barrel is fixedly installed on the upper part of the feeding cylinder, a material dropping seat is fixedly installed inside the base, a stirring mechanism is provided at the bottom of the base, an mounting base is fixedly installed at the bottom of the base, and a weighing mechanism is provided at one end of the feeding cylinder inside the base.

[0006] For example, patent application number CN202122782040.4 discloses a weighing-type color masterbatch machine, including a main hopper, a base, a color masterbatch hopper, and a feeding mechanism. The lower end outlet of the main hopper is connected to the base, and the lower end outlet of the color masterbatch hopper is connected to the feeding mechanism. The color masterbatch is conveyed to the base through the feeding mechanism. A fixed frame is provided on one side of the base, and the feeding mechanism is provided on the mounting frame. The mounting frame is slidably mounted on the fixed frame in the horizontal direction. A weighing sensor is fixed on the fixed frame, and the weighing sensor is in contact with the bottom of the mounting frame.

[0007] As can be seen from the above patents, the existing color masterbatch machine includes a material discharge base, an electrical control box, a stirring mechanism inside the material discharge base, a main material barrel at the top of the material discharge base, a color masterbatch barrel next to the main material barrel, and a spiral feeding mechanism at the bottom of the color masterbatch barrel and connected to the material discharge base. The bottom of the material discharge base is connected to the extruder, and the color masterbatch is quantitatively transported to the material discharge base and mixed with the raw materials through the spiral feeding mechanism.

[0008] During actual production, the applicant discovered that the amount of color masterbatch added is relatively small, ranging from 0.5% to 10% of the raw material weight, typically 1% to 3%. Due to the small amount of color masterbatch, the accuracy of its addition is extremely important. If the color masterbatch container is empty, the screw feeding mechanism will run idle, leading to inaccurate feeding. Summary of the Invention

[0025] The main material tank 3, shell 16, and discharge base 1 are arranged sequentially from top to bottom, while the color masterbatch tank 4, color masterbatch weighing hopper 8, and screw feeding mechanism 5 are arranged sequentially from top to bottom. The main material tank 3, shell 16, and discharge base 1 are all vertically oriented. Specifically, the shell 16 is a vertically oriented rectangular frame with through holes on both its upper and lower sides for material passage. The mixing mechanism 2 is located at the lower part of the discharge base 1 and includes a mixer and a motor. Specifically, the mixing blades of the mixing mechanism 2 are arranged in a front-to-back direction, and its motor is located on the outer rear side of the discharge base 1, away from the lower support 14. The bottom of the discharge base 1 has a discharge port and a mounting base, which is installed on the extruder.

[0026] The main material hopper 3 is located at the top outside the shell 16, and a main metering valve 9 is installed at the discharge port at its bottom. It is vertically arranged. The main weighing scale 11 is located at the bottom inside the shell 16. The main weighing hopper 7 is located inside the shell 16, directly below the main material hopper 3, and is installed on the main weighing scale 11. Its discharge port at the bottom (inserted into the inlet at the top of the discharge base 1) outputs the material to the discharge base 1. It is vertically arranged.

[0027] The electrical control box 6 is located on the left or right side of the housing 16 and is used to control the entire device. The alarm 15 is an audible and visual alarm and is located on top of the electrical control box 6. The upper bracket 13 is located in the middle of the other side (right or left) of the housing 16. The lower bracket 14 is located on the upper part of the material dropping base 1 away from the electrical control box 6 (specifically, the right or left side of the material dropping base 1) and is directly below the upper bracket 13. Both the upper bracket 13 and the lower bracket 14 are arranged in a left-right direction and each has a through hole for the color masterbatch to pass through.

[0028] Among them, the color masterbatch 4 is installed on the upper support 13. It is vertically arranged and located next to the main material tank 3. It is arranged side by side with the main material tank 3. It is lower than the main material tank 3 and its volume is smaller than that of the main material tank 3. A color masterbatch metering valve 10 is provided on the discharge port at its bottom.

[0029] The color masterbatch weighing scale 12 and the screw feeding mechanism 5 are respectively located on the upper and lower sides of the lower support 14. The color masterbatch weighing hopper 8 is located on the color masterbatch weighing scale 12, vertically positioned below the upper support 13 and directly below the color masterbatch barrel 4, arranged side by side with the shell 16. Its bottom outlet (inserted into the inlet at the top of the screw feeding mechanism 5) outputs the color masterbatch to the screw feeding mechanism 5, and its volume is smaller than that of the main weighing hopper 7. The screw feeding mechanism 5 is arranged in a left-right direction, and its output end (left end or rear end) extends into the upper part of the discharge base 1.

[0030] The main weighing scale 11, the color masterbatch weighing scale 12, and the alarm 15 are all electrically connected to the control box 6. The control box 6 controls the opening and closing of the main metering valve 9 and the color masterbatch metering valve 10 based on the detection values ​​of the main weighing scale 11 and the color masterbatch weighing scale 12, respectively. When the detection value of the color masterbatch weighing scale 12 is less than a first predetermined weight (such as 1 / 5 to 1 / 4 of the maximum load weight in the color masterbatch weighing hopper, which can be set according to actual needs), the alarm 15 will sound.

[0031] The operating process of this device is as follows: When the detection value of the masterbatch weighing scale 12 is less than the second predetermined weight (e.g., 1 / 2 of the maximum load weight in the masterbatch weighing hopper), the masterbatch metering valve 10 opens, and the masterbatch from the masterbatch tank 4 flows into the masterbatch weighing hopper 8. If the detection value of the masterbatch weighing scale 12 is greater than the third predetermined weight (e.g., 2 / 3 of the maximum load weight in the masterbatch weighing hopper), the masterbatch metering valve 10 closes, ensuring that there is always masterbatch in the masterbatch weighing hopper 8. If there is no masterbatch in the masterbatch tank 4, even if the masterbatch metering valve 10 is open, if the detection value of the masterbatch weighing scale 12 is less than the first predetermined weight (e.g., 1 / 5-1 / 4 of the maximum load weight in the masterbatch weighing hopper), the alarm 15 will sound to remind the operator to add masterbatch to the masterbatch tank 4 or that the automatic feeding equipment of the masterbatch tank 4 is malfunctioning.

[0032] Among them, see Figure 1 In this embodiment of the present invention, both the main metering valve 9 and the color masterbatch metering valve 10 are pneumatic valves. The front side of the electrical control box 6 is provided with a pressure regulating valve 19 for adjusting the gas supply of the main metering valve 9 and the color masterbatch metering valve 10.

[0033] Specifically, see Figure 1 In this embodiment of the present invention, the volume of the main material bucket 3 is 2-5 times that of the color masterbatch bucket 4, the volume of the main weighing hopper 7 is 0.2-0.5 times that of the main material bucket 3, and the volume of the color masterbatch weighing hopper 8 is 0.1-0.4 times that of the main weighing hopper 7.
