Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, specifically a color masterbatch raw material proportioning machine that can accurately measure raw materials. Background Technology

[0002] In various industries such as plastics, chemical fibers, and rubber, color masterbatch is used more and more widely as an important colorant and functional additive. Color masterbatch can give products a rich variety of colors and improve their physical properties and processing performance. As the market continues to raise the requirements for product quality and appearance, higher standards are also being set for the quality of color masterbatch. Accurate raw material ratio is one of the key factors to ensure the quality of color masterbatch, which directly affects the color stability, performance consistency and other indicators of the product.

[0003] Currently, there are various technical methods for the proportioning of color masterbatch raw materials. Manual batching is still used in some small enterprises or in scenarios where high precision is not required. Workers weigh each color masterbatch raw material one by one according to the formula, and then manually stir and mix them. This method relies on manual operation, the process is simple and direct, and does not require investment in complex equipment. Some enterprises of a certain scale use volumetric metering equipment. This equipment uses a cavity of a specific shape and size to quantitatively measure the color masterbatch raw materials. During operation, the motor drives the screw or impeller and other components to make the raw materials enter the metering cavity from the feed port. After filling, they are discharged from the discharge port. The amount of raw materials is controlled by controlling the number of fillings of the metering cavity and the motor speed. In addition, weighing metering equipment is also used in some enterprises with high precision requirements. The raw materials fall from the silo to the weighing platform through the conveying device. The high-precision sensor converts the weight signal into an electrical signal and transmits it to the control system. When the preset weight is reached, the conveying device stops feeding, and the metering is completed.

[0004] Although manual batching requires low initial equipment investment, in the long run, labor costs are high. Due to the low efficiency of manual weighing, a large number of people are needed for large-scale production, which increases labor costs. Moreover, manual operation is prone to errors, resulting in unstable product quality and increased scrap rate, which further increases production costs. The mechanical structure of volumetric metering equipment is relatively complex with many parts. During the production process, these parts are easily damaged by friction and impact of raw materials, resulting in high equipment maintenance costs. Utility Model Content

The front side wall of the measuring wheel is rotatably connected to a rotating shaft. The rear end of the rotating shaft is provided with a gear. The gear is located inside the adjusting groove and meshes with the rack plate to adjust the position of the adjusting plate inside the measuring groove.

[0010] Furthermore, the front side of the measuring wheel is provided with a mounting cylinder, the front end of which passes through the middle of the front side wall of the mixing chamber.

A feed pipe 10 is provided at the feed inlet on the upper side wall of the proportioning tank 1. A stirring shaft 11 is rotatably connected to the inclined surface of the top wall of the proportioning tank 1. A motor 12 is installed on the inclined surface of the right end of the proportioning tank 1. The output shaft of the motor 12 is fixedly connected to the center of the shaft end face of the stirring shaft 11. The input end of the motor 12 is electrically connected to the output end of the control switch group 14. A valve 13 is connected in series in the middle of the discharge pipe at the lower end of the proportioning tank 1. The input end of the valve 13 is electrically connected to the output end of the control switch group 14.

[0025] The system also includes a proportioning mechanism 2. The proportioning mechanism 2 comprises a proportioning bin 21, a metering wheel 22, a metering groove 23, and an adjusting plate 24. The proportioning bin 21 is connected in series in the middle of the feed pipe 10. The metering wheel 22 is rotatably connected inside the proportioning bin 21 (the outer arc surface of the metering wheel 22 is in contact with the inner arc surface of the proportioning bin 21). A metering groove 23 is formed at the upper end of the outer arc surface of the metering wheel 22, and an adjusting plate 24 is slidably connected inside the metering groove 23. The proportioning mechanism 2 also includes a sliding hole 25 and a sliding column 26. An adjusting groove 221 is formed inside the metering wheel 22, and a sliding hole 25 is formed on the right side of the bottom wall of the metering groove 23. The internal sliding connection includes a sliding column 26, the upper side of which is fixedly connected to the lower side of the adjusting plate 24, and the lower end of the sliding column 26 is located inside the adjusting groove 221. The proportioning mechanism 2 also includes a rack plate 27, a clearance groove 28, and a gear 29. The lower side of the adjusting plate 24 is provided with a rack plate 27, and the lower end of the rack plate 27 passes through the clearance groove 28 opened on the left side of the bottom wall of the adjusting groove 221. The front side wall of the measuring wheel 22 is rotatably connected to a rotating shaft 6, and the rear end of the rotating shaft 6 is provided with a gear 29. The gear 29 is located inside the adjusting groove 221 and meshes with the rack plate 27.

[0026] The metering wheel 22 has a mounting cylinder 3 on its front side. The front end of the mounting cylinder 3 passes through the middle of the front side wall of the mixing chamber 21. The front end of the rotating shaft 6 is located inside the mounting cylinder 3. The outer arc surface of the mounting cylinder 3 has a scale 4. The upper end of the outer arc surface of the scale 4 has a direction pointer 5 (the direction pointer 5 is used to point to the opening position of the metering groove 23). The upper end of the outer arc surface of the rotating shaft 6 has a pointer 7. The pointer 7 is located in front of the scale 4. The left end of the mounting cylinder 3 is threaded with a tightening screw 8. The tightening screw 8 is set to cooperate with the rotating shaft 6. The rear side of the mixing chamber 21 is equipped with a motor 9. The output shaft of the motor 9 is fixedly connected to the center of the rear end face of the metering wheel 22. The input end of the motor 9 is electrically connected to the output end of the control switch group 14.

[0027] The working principle of this utility model is as follows:

[0028] By connecting the external power supply through the control switch group 14, the equipment is started. According to the actual production needs, the top screw 8 at the left end of the mounting cylinder 3 is rotated to loosen the fixation of the rotating shaft 6. Then, the rotating shaft 6 is manually rotated. The rotating shaft 6 drives the gear 29 to rotate. Since the gear 29 meshes with the rack plate 27, the rack plate 27 will drive the adjusting plate 24 to slide in the metering groove 23.

[0029] During this process, the sliding column 26 slides within the sliding hole 25, providing stable guidance and support for the adjusting plate 24. By observing the position change of the pointer 7 on the scale 4, the adjusting plate 24 is adjusted to a suitable position, thereby determining the actual volume of the metering tank 23 to meet the metering requirements of different masterbatch raw materials.

[0030] After adjustment, tighten the top screw 8 to fix the rotating shaft 6, so that the position of the adjusting plate 24 remains stable. Turn on the control switch group 14, and the motor 9 is powered on and started. Its output shaft drives the metering wheel 22 to rotate in the proportioning bin 21. As the metering wheel 22 rotates, the whole assembly consisting of the mounting cylinder 3, the scale 4 and the direction pointer 5 also rotates. When the direction pointer 5 points directly upward, operate the control switch group 14 to stop the motor 9. The opening of the metering tank 23 faces upward, and the worker puts the color masterbatch raw material into the feed pipe 10. Then, the color masterbatch raw material enters the metering tank 23 under the action of gravity. Since the adjusting plate 24 has been pre-adjusted, the amount of raw material contained in the metering tank 23 each time is fixed and accurate.

[0031] Then, the control switch group 14 makes the motor 9 run again, the metering wheel 22 continues to rotate, the metering tank 23 filled with raw materials faces downward, the color masterbatch raw materials fall into the lower half of the feed pipe 10 by gravity, and continue to be conveyed to the proportioning tank 1, accurately measuring the color masterbatch raw materials that need to be proportioned.

[0032] At the same time, the motor 12 is powered on and its output shaft drives the stirring shaft 11 to rotate in the mixing tank 1. The various color masterbatch raw materials entering the mixing tank 1 are gradually mixed evenly under the stirring action of the stirring shaft 11, ensuring that the color masterbatch raw materials are fully integrated in the mixing tank and achieve the expected mixing effect. After the color masterbatch raw materials are mixed evenly in the mixing tank 1, the valve 13 is opened by the control switch group 14, and the mixed color masterbatch raw materials are discharged from the discharge pipe at the lower end of the mixing tank 1 and enter the subsequent production process.

[0033] It is worth noting that the motor 12 disclosed in the above embodiments can be model 90W-AC-220V, the valve 13 can be model 4WE6E6X / EG24N9K4, the motor 9 can be model 57BLDCM-50W-3000RPM, and the control switch group 14 is provided with control buttons that correspond one-to-one with the motor 9, the motor 12 and the valve 13 and are used to control their switching.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
