Description

Technical Field

[0001] This utility model relates to the field of color masterbatch production technology, specifically to a color masterbatch drying and screening device. Background Technology

[0002] Masterbatch is a core coloring material in the processing of plastics, chemical fibers and other products. Traditional masterbatch drying and screening equipment is a key piece of equipment in masterbatch production. It is mainly used in plastic processing plants, masterbatch production enterprises and other scenarios to remove moisture from masterbatch, separate impurities and particles of different sizes, ensure that the masterbatch is uniformly mixed with the substrate, and ensure the color consistency and physical properties of the molded products.

[0003] However, in scenarios requiring multi-particle-size grading and screening, and continuous batch production, traditional drying and screening equipment are mostly independent, with dispersed processes. The transfer process can easily lead to secondary moisture absorption of the masterbatch. At the same time, the connection between drying and screening is not continuous, making it difficult to adapt to the efficient and flexible processing needs of large-scale production. Utility Model Content

[0004] This invention provides a color masterbatch drying and screening device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

A mode switching mechanism includes a second motor, a second gear fixedly connected to one end of the second motor shaft, and a second gear meshing with the surface of the second gear.

[0007] A further improvement of this utility model is that the dual-purpose drying and sieving mechanism also includes a rotating ring, the surface of which is rotatably connected to both ends of the multifunctional inner cylinder.

[0008] A further improvement of this utility model is that the side of the rotating ring away from the multifunctional inner cylinder is fixedly connected to both sides of the inner cavity of the mounting frame, and a rotating block is rotatably connected to the middle of both ends of the multifunctional inner cylinder.

[0009] A further improvement of this utility model is that the side of the rotating block away from the multifunctional inner cylinder is fixedly connected to both sides of the inner cavity of the mounting frame, and an exhaust pipe is fixedly connected inside the rotating block on the left side.

[0010] A further improvement of this utility model is that: a feed pipe with a built-in solenoid valve is fixedly connected to the upper end of the rotating block on the right side, and one end of the feed pipe is connected to the interior of the multifunctional inner cylinder.

[0011] A further improvement of this utility model is that: a feeding hopper is fixedly connected to the other end of the feeding pipe, and an air inlet pipe is fixedly connected to the lower end of the rotating block on the right side, with one end of the air inlet pipe connected to a hot air blower.

[0012] A further improvement of this utility model is that the surface of the multifunctional inner cylinder is provided with a closed area, a discharge hole area, a large sieve hole area and a small sieve hole area. The closed area, discharge hole area, large sieve hole area and small sieve hole area are evenly distributed in a circumferential array on the surface of the multifunctional inner cylinder, and the areas of the closed area, discharge hole area, large sieve hole area and small sieve hole area are the same.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a color masterbatch drying and screening device. By adopting an integrated drying and screening design, the color masterbatch is dried and screened in a multi-functional inner cylinder without the need for transfer, thus avoiding secondary moisture absorption caused by contact with air. During drying, the closed area is used in conjunction with the hot air fan for air intake and the exhaust pipe for moisture removal to form a drying environment and ensure the drying effect.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1, as Figures 1-8 As shown, this utility model provides a color masterbatch drying and screening device, including a drying and screening dual-purpose mechanism. The drying and screening dual-purpose mechanism includes a mounting frame 11, a material discharge chamber 12 is provided at the lower end of the mounting frame 11, a first motor 13 is fixedly connected to one side of the mounting frame 11, a first gear 14 is fixedly connected to one end of the shaft of the first motor 13, a first gear ring 15 is meshed on the surface of the first gear 14, and a multi-functional inner cylinder 16 is fixedly connected to one side of the first gear ring 15; a mode switching mechanism, including a second motor 21, a second gear 22 is fixedly connected to one end of the shaft of the second motor 21, and a second gear ring 23 is meshed on the surface of the second gear 22.

[0027] In this embodiment, the starting mode switching mechanism activates the second motor 21, which drives the second gear 22 to rotate. The second gear ring 23, which meshes with the second gear, rotates synchronously, thereby causing the sealing outer cylinder 24 to rotate around the surface of the multifunctional inner cylinder 16. If drying is required first, the functional area starting notch 25 of the sealing outer cylinder is aligned with the closed area 161 of the multifunctional inner cylinder 16, so that the closed area 161 seals the functional area starting notch 25. If direct screening is required, the functional area starting notch 25 is aligned with the small sieve hole area 164. After adjustment, the fixing screw 27 is screwed into the fixing hole 26 of the second gear ring 23 until one end abuts against the end of the multifunctional inner cylinder 16, locking the position of the sealing outer cylinder and preventing displacement during operation.

[0028] Example 2, as Figures 1-8 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the drying and sieving dual-purpose mechanism further includes a rotating ring 17. The surface of the rotating ring 17 is rotatably connected to both ends of the multifunctional inner cylinder 16. The side of the rotating ring 17 away from the multifunctional inner cylinder 16 is fixedly connected to both sides of the inner cavity of the mounting frame 11. A rotating block 18 is rotatably connected to the middle of both ends of the multifunctional inner cylinder 16. The side of the rotating block 18 away from the multifunctional inner cylinder 16 is fixedly connected to both sides of the inner cavity of the mounting frame 11. An exhaust pipe 19 is fixedly connected inside the left rotating block 18. A feed pipe 110 with a built-in solenoid valve is fixedly connected inside the upper end of the right rotating block 18. One end of the feed pipe 110 communicates with the interior of the multifunctional inner cylinder 16, and the other end of the feed pipe 110 is fixedly connected to a feed hopper. An air inlet pipe is fixedly connected inside the lower end of the right rotating block 18, and one end of the air inlet pipe is connected to a hot air blower 111.

[0029] In this embodiment, the masterbatch to be processed is poured into the feed hopper by opening the solenoid valve built into the feed pipe 110, and the masterbatch enters the multifunctional inner cylinder 16 through the feed pipe 110. After feeding is completed, the solenoid valve is closed to prevent material leakage during drying or screening; at the same time, the hot air blower 111 is started, and the hot air generated by it is continuously delivered to the multifunctional inner cylinder 16 through the air inlet pipe in the right rotating block 18 to prepare for the drying process. The first motor 13 of the drying and screening mechanism is started, and the first motor shaft drives the first gear 14 to rotate. The first gear ring 15 meshing with the first gear rotates accordingly, thereby driving the multifunctional inner cylinder 16 to rotate around the rotating block 18 and the rotating ring 17. At this time, the closed area 161 of the multifunctional inner cylinder seals the functional area start-up gap 25, forming a sealed space. The hot air in the sealed space fully contacts the rotating masterbatch and evenly removes the moisture from the material; the moisture is discharged through the exhaust pipe 19 in the left rotating block 18, realizing the drying of the masterbatch.

[0030] Example 3, as Figures 1-8As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the surface of the multifunctional inner cylinder 16 is provided with a closed area 161, a discharge hole area 162, a large sieve hole area 163, and a small sieve hole area 164. The closed area 161, the discharge hole area 162, the large sieve hole area 163, and the small sieve hole area 164 are evenly distributed in a circumferential array on the surface of the multifunctional inner cylinder 16. The closed area 161, the discharge hole area 162, the large sieve hole area 163, and the small sieve hole area 164 have the same area. The mode switching mechanism also includes a sealing outer cylinder 24. The sealing outer cylinder 24... One end is fixedly connected to the surface of the second toothed ring 23. The inner wall of the sealing outer cylinder 24 overlaps with the surface of the multifunctional inner cylinder 16, and the end is rotatably connected to the end of the multifunctional inner cylinder 16. The surface of the sealing outer cylinder 24 is provided with a functional area start-up notch 25. The area of ​​the functional area start-up notch 25 is larger than the small sieve hole area 164. The surface of the second toothed ring 23 is provided with a fixing hole 26. Four fixing holes 26 are evenly arranged along the surface of the second toothed ring 23. The fixing hole 26 is internally threaded with a fixing screw 27. One end of the fixing screw 27 abuts against the end of the multifunctional inner cylinder 16.

[0031] In this embodiment, during the drying process, the drying temperature and material turning frequency can be controlled by adjusting the air volume of the hot air blower and the speed of the first motor, ensuring uniform drying. After drying, if screening is required, unscrew the fixing screw 27, restart the second motor 21, adjust the starting notch 25 of the functional area of ​​the sealing outer cylinder to align with the small sieve hole area, and screw the fixing screw 27 back into the corresponding fixing hole 26 to lock the sealing outer cylinder. Subsequently, the first motor 13 operates, and the multifunctional inner cylinder 16 continues to rotate. The color masterbatch inside moves towards the cylinder wall under the action of centrifugal force. Color masterbatch that meets the sieve hole size falls into the lower discharge chamber 12 through the sieve hole area. Then, the same method is used to replace the large sieve hole area 163. After screening again, oversized impurities or substandard materials remain in the multifunctional inner cylinder, achieving graded screening without disassembling and replacing the sieve. After screening, the discharge hole area 162 is aligned with the starting notch 25 of the functional area again using the same method, and the first motor 13 is started to discharge oversized impurities or substandard materials.

[0032] The working principle of this masterbatch drying and screening device will be explained in detail below.

[0033] like Figures 1-8As shown, according to processing requirements, the start-up mode switching mechanism is activated as follows: the second motor 21 is powered on, driving the second gear 22 to rotate, and the second gear ring 23, which meshes with the second gear, rotates synchronously, thereby driving the sealing outer cylinder 24 to rotate around the surface of the multifunctional inner cylinder 16. If drying is required first, align the functional area start-up notch 25 of the sealing outer cylinder with the closed area 161 of the multifunctional inner cylinder 16, so that the closed area 161 seals the functional area start-up notch 25; if direct screening is required, align the functional area start-up notch 25 with the small sieve hole area 164. After adjustment, screw the fixing screw 27 into the fixing hole 26 of the second gear ring 23 until one end abuts against the end of the multifunctional inner cylinder 16, locking the position of the sealing outer cylinder and preventing displacement during operation. Open the solenoid valve built into the feed pipe 110 and pour the color masterbatch to be processed into the feed hopper. The color masterbatch enters the interior of the multifunctional inner cylinder 16 through the feed pipe 110. After feeding is completed, the solenoid valve is closed to prevent material leakage during drying or screening. Simultaneously, the hot air blower 111 is started, and the hot air it generates is continuously delivered to the multi-functional inner cylinder 16 through the air inlet pipe inside the right rotating block 18, preparing for the drying process. The first motor 13 of the drying and screening mechanism is started, and the first motor shaft drives the first gear 14 to rotate. The first gear ring 15, which meshes with the first gear, rotates accordingly, thereby driving the multi-functional inner cylinder 16 to rotate around the rotating block 18 and the rotating ring 17. At this time, the closed area 161 of the multi-functional inner cylinder seals the functional area starting gap 25, forming a sealed space. The hot air in the sealed space fully contacts the rotating masterbatch, evenly removing moisture from the material. The moisture is discharged through the exhaust pipe 19 inside the left rotating block 18, achieving the drying of the masterbatch. During the drying process, the drying temperature and material turning frequency can be controlled by adjusting the airflow of the hot air blower and the speed of the first motor to ensure drying uniformity. After drying, if screening is required, unscrew the fixing screw 27, restart the second motor 21, adjust the starting notch 25 of the sealing outer cylinder to align with the small sieve hole area, and screw the fixing screw 27 back into the corresponding fixing hole 26 to lock the sealing outer cylinder. Then, the first motor 13 operates, and the multi-functional inner cylinder 16 continues to rotate. The masterbatch inside moves towards the cylinder wall under centrifugal force. Masterbatch that meets the sieve hole size falls through the sieve hole area into the lower discharge chamber 12. Then, similarly, the large sieve hole area 163 is used for screening again. Oversized impurities or substandard materials remain in the multi-functional inner cylinder, achieving grading screening without disassembling or replacing the sieve. After screening, align the discharge hole area 162 with the starting notch 25 of the functional area using the same method, and start the first motor 13 to discharge oversized impurities or substandard materials.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
