Description

Technical Field

[0001] This utility model relates to the field of color masterbatch screening technology, and in particular to a screening device for color masterbatch processing. Background Technology

[0002] In the processing and production of color masterbatches, screening is one of the key steps to ensure product quality. The particle size and uniformity of color masterbatches directly affect their performance in subsequent processing, such as dispersibility and coloring effect. However, existing color masterbatch screening equipment has many problems in practical applications and cannot meet the needs of modern color masterbatch production for efficient and precise screening as well as adaptability to continuous production.

[0003] Traditional masterbatch screening equipment mostly uses a single screen structure, resulting in a relatively simple screening method. During the screening process, the masterbatch passes through the screen by its own gravity or simple vibration, which is inefficient. Furthermore, the discharge process after screening is also cumbersome, usually requiring additional operations to remove the screened masterbatch from the equipment, increasing the complexity of the production process. Therefore, it is necessary to design a screening device for masterbatch processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screening device for color masterbatch processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for color masterbatch processing includes a base, a rotating drum above the base, a first cylindrical screen plate fixed on the inner wall of the rotating drum, a second cylindrical screen plate fixed on the inner wall of the first cylindrical screen plate, spiral guide plates fixed on the inner walls of the rotating drum, the first cylindrical screen plate, and the second cylindrical screen plate, and two support frames fitted on the outer wall of the rotating drum, the rotating drum being rotatably connected to the support frames, and a feeding mechanism and a rotating mechanism provided on the side wall of the support frame near the closed end of the rotating drum.

[0007] As a further improvement of this utility model, the feeding mechanism includes a fixed plate fixedly connected to the side wall of the support frame, and a feeding hopper fixedly connected to the fixed plate is provided through the fixed plate. The feeding hopper passes through the closed end of the rotating drum, the closed end of the first cylindrical screen plate, and the closed end of the second cylindrical screen plate, and the feeding hopper is rotatably connected to the rotating drum, the first cylindrical screen plate, and the second cylindrical screen plate.

[0008] As a further improvement of this utility model, the rotating mechanism includes a motor mounted on the side wall of the support frame, the output shaft of the motor is fixedly connected to a gear, and a gear ring is fixedly sleeved on the side wall of the rotating drum, the gear ring meshing with the gear.

[0009] As a further improvement of this utility model, the upper end of the base is provided with three placement slots, which are respectively located below the opening end of the rotating drum, the opening end of the first cylindrical sieve plate, and the opening end of the second cylindrical sieve plate. The interior of each placement slot is provided with a collection mechanism.

[0010] As a further improvement of this utility model, the collection mechanism includes a collection box disposed inside the placement slot, and handles are fixed on both opposite side walls of the collection box.

[0011] As a further improvement of this utility model, the lower end of the support frame is fixedly connected to two fixing rods, and the lower ends of the fixing rods are fixedly connected to the upper end of the base.

[0012] The beneficial effects of this utility model are:

[0013] By using the coaxial nesting design of the rotating drum, the first cylindrical screen plate, and the second cylindrical screen plate, combined with the spiral guide plate, the color masterbatch is pushed, turned, and automatically screened in multiple stages by applying continuous axial thrust when the spiral guide plate rotates. The screened color masterbatch can be directly discharged, which greatly improves the screening efficiency and significantly increases the batch processing efficiency. It is particularly suitable for the high-frequency operation requirements of continuous production lines. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A screening device for color masterbatch processing includes a base 1, a rotating drum 6 above the base 1, a first cylindrical screen plate 7 fixed on the inner wall of the rotating drum 6, a second cylindrical screen plate 8 fixed on the inner wall of the first cylindrical screen plate 7, and spiral guide plates 9 fixed on the inner walls of the rotating drum 6, the first cylindrical screen plate 7, and the second cylindrical screen plate 8. The first cylindrical screen plate 7 and the second cylindrical screen plate 8 can be used to screen the color masterbatch in multiple stages. Two support frames 3 are fitted on the outer wall of the rotating drum 6. Two fixing rods 2 are fixedly connected to the lower end of the support frame 3. The lower end of the fixing rods 2 is fixedly connected to the upper end of the base 1. The rotating drum 6 is rotatably connected to the support frame 3. A feeding mechanism and a rotating mechanism are provided on the side wall of the support frame 3 near the closed end of the rotating drum 6.

[0021] In this utility model, the feeding mechanism includes a fixed plate 4 fixedly connected to the side wall of the support frame 3. A feeding hopper 5 is fixedly connected to the fixed plate 4 and passes through the fixed plate 4. The feeding hopper 5 passes through the closed end of the rotating drum 6, the closed end of the first cylindrical screen plate 7, and the closed end of the second cylindrical screen plate 8. The feeding hopper 5 is rotatably connected to the rotating drum 6, the first cylindrical screen plate 7, and the second cylindrical screen plate 8. By adding the masterbatch into the feeding hopper 5, the masterbatch can be guided into the interior of the second cylindrical screen plate 8. Then, the masterbatch is screened by the second cylindrical screen plate 8 and the first cylindrical screen plate 7.

[0022] The rotating mechanism includes a motor 14 mounted on the side wall of the support frame 3. The output shaft of the motor 14 is fixedly connected to a gear 13. A gear ring 12 is fixedly sleeved on the side wall of the rotating drum 6. The gear ring 12 meshes with the gear 13. By starting the motor 14, the gear 13 is driven to rotate. The meshing of the gear ring 12 and the gear 13 drives the rotating drum 6 to rotate, thereby driving the first cylindrical screen plate 7 and the second cylindrical screen plate 8 to rotate. At the same time, it can drive the spiral guide plate 9 to rotate. The spiral guide plate 9 can continuously push the masterbatch forward, realizing the automatic discharge of the screened masterbatch. This greatly improves the efficiency of masterbatch screening by achieving automatic screening and separate discharge of masterbatch.

[0023] The upper end of the base 1 is provided with three placement slots 15. The three placement slots 15 are respectively located below the opening end of the rotating drum 6, the opening end of the first cylindrical sieve plate 7, and the opening end of the second cylindrical sieve plate 8. The interior of the placement slot 15 is provided with a collection mechanism, which includes a collection box 10 set inside the placement slot 15. The collection box 10 has handles 11 fixed on its opposite side walls. The sieved masterbatch can be collected separately through multiple collection boxes 10.

[0024] When this utility model is in use, after the motor 14 is started, its output shaft drives the gear 13 to rotate. Through meshing with the gear ring 12 fixedly sleeved on the side wall of the rotating drum 6, the rotating drum 6 is driven to rotate under the constraint of the two support frames 3. At the same time, the rotating drum 6 drives the first cylindrical screen plate 7 and the second cylindrical screen plate 8, which are coaxially installed inside, to rotate synchronously.

[0025] Then, the color masterbatch raw material is continuously fed in through the feed hopper 5 on the fixed plate 4. The color masterbatch is accurately introduced into the second cylindrical screen plate 8. During the rotation, the spiral guide plate 9 fixed on the inner wall of each cylinder continuously pushes the color masterbatch to move axially. The smaller particle size color masterbatch passes through the mesh of the second cylindrical screen plate 8 and enters the cavity of the first cylindrical screen plate 7, and then passes through the mesh of the first cylindrical screen plate 7 and enters the cavity of the rotating cylinder 6. The largest particle size color masterbatch is retained inside the second cylindrical screen plate 8. Finally, the color masterbatch separated from the three cylinders is discharged from its opening end and falls into the collection box 10 pre-set in the three placement slots 15 at the upper end of the base 1. The operator can conveniently pick up and put in color masterbatch of different particle size grades through the handle 11 fixed on the side wall of the collection box 10.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
