Description

Technical Field

[0001] This utility model belongs to the technical field of functional plastic masterbatch screening equipment, and particularly relates to a multi-stage screening device for functional plastic masterbatch. Background Technology

[0002] Functional plastic masterbatch is a granular product made by using resin as a carrier, compounding basic additives such as dispersants and stabilizers, and selectively adding core additives with specific functions (such as antistatic agents, antibacterial agents, UV stabilizers, flame retardants, thermal conductive agents, toughening agents, etc.). After scientific formulation, mixing, and modification, it is produced by extrusion and granulation. The processing requires a vibrating screen, which is a device that uses a vibrating motor or eccentric shaft to generate periodic vibrations, classifying, screening, removing impurities, or filtering granular, powdery, or lumpy materials through a screen.

[0003] To stabilize the screen position and ensure flexible connection, vibrating screens require many springs for positioning, resulting in a complex internal mechanical structure and thus low practicality of conventional vibrating screens.

[0004] To address this issue, we propose a multi-stage screening device for functional plastic masterbatch. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low practicality of conventional vibrating screens, and to propose a functional plastic masterbatch multi-screening device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage screening device for functional plastic masterbatch includes a motor and a vibrator. A frame is fixedly connected to the outside of the motor. A spring-loaded rotating column is fixedly connected to the output shaft of the motor. The upper part of the spring-loaded rotating column is rotatably mounted on the frame. A spring-loaded frame is rotatably connected to the upper part of the frame. The spring-loaded frame is rotatably connected to the spring-loaded rotating column and fixedly connected to the vibrator. A disc screen is fixedly connected to the spring-loaded rotating column. A connecting block is fixedly connected to the middle of the frame, and a guide shell is fixedly connected to the connecting block. Material is placed into the disc screen. An external power supply drives the vibrator to vibrate the spring-loaded frame. The spring-loaded frame acts on the spring-loaded rotating column, which in turn acts on the disc screen, causing it to vibrate. The motor screens the material layer by layer. After screening, the vibrator is turned off, and the motor is driven to rotate the disc screen. The disc screen rotates the material remaining in it, throwing it into the guide shell for discharge. This simple structure achieves multi-stage screening, improving practicality.

[0007] Preferably, the frame includes a frame body, a support is fixedly connected to the lower end of the frame body, a first bearing seat is fixedly connected to the upper part of the frame body, the upper part of the motor is fixedly connected to the frame body, and the connecting block is fixedly connected to the frame body.

[0008] Preferably, the elastic frame includes a spring plate, one end of which is fixedly connected to the frame body, and the other end of which is fixedly connected to a second bearing seat. A fixing block is fixedly connected to one end of the second bearing seat, and the fixing block is fixedly connected to the lower end of the vibrator. The vibrator drives the fixing block to vibrate, which in turn acts on the second bearing seat, which in turn acts on the elastic rotating column, facilitating the vibration of the elastic rotating column by the vibrator.

[0009] Preferably, the elastic rotating column includes a column body, with a turntable fixedly connected to the upper end of the column body. The upper part of the column body is rotatably connected to a first bearing seat, and the turntable is fixedly connected to the output shaft of the motor. The motor drives the turntable to rotate, which in turn drives the column body to rotate, thereby causing the column body to drive the disc screen to rotate, facilitating the discharge of residual materials by centrifugal force.

[0010] Preferably, the disc screen includes a screen mesh, with a bucket-shaped ring fixedly connected to the outer periphery of the screen mesh, and a connecting sleeve fixedly connected to the middle of the screen mesh, the connecting sleeve being fixedly connected to the outside of the column. When the column vibrates, the column acts on the connecting sleeve, which in turn acts on the screen mesh, and the screen mesh acts on the material, thus sieving the material. When the column rotates, the column drives the connecting sleeve to rotate, which in turn drives the screen mesh to rotate, causing the material to rotate and be thrown towards the bucket-shaped ring, where it is guided upwards and discharged, facilitating sieving and discharge.

[0011] Preferably, the guide shell includes a housing, a baffle ring fixedly connected to the upper end of the housing, and a discharge nozzle fixedly connected to the lower part of the housing. The internal spaces of the baffle ring and the discharge nozzle are connected. The screen is fixedly connected to the connecting block. The hopper-shaped ring is located inside the housing and the baffle ring, and the hopper-shaped ring does not contact the housing or the baffle ring. The baffle ring blocks the upper side of the hopper-shaped ring to prevent material from flying upwards. The housing guides the material into the discharge nozzle, and the material is discharged outwards through the discharge nozzle, facilitating centralized material discharge.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. Place the material into the disc screen, and use an external power source to drive the vibrator to vibrate the elastic frame. The elastic frame acts on the elastic rotating column, which in turn acts on the disc screen, causing it to vibrate. The motor then filters the material layer by layer. After screening, turn off the vibrator and drive the motor to rotate the disc screen. The disc screen then rotates the material remaining inside, throwing it into the guide shell and discharging it outwards. This simple structure achieves multi-layer screening, improving practicality.

[0013] 2. The vibrator drives the fixed block to vibrate, and the fixed block acts on the second bearing seat, which in turn acts on the elastic rotating column, making it convenient for the vibrator to drive the elastic rotating column to vibrate.

[0014] 3. The motor drives the turntable to rotate, which in turn drives the column to rotate, which in turn drives the disc screen to rotate, making it easy to discharge residual materials by means of centrifugal force.

[0015] 4. When the column vibrates, the column acts on the connecting sleeve, which in turn acts on the screen, which in turn acts on the material. The screen then sieves the material. When the column rotates, it drives the connecting sleeve to rotate, which in turn drives the screen to rotate. The screen then drives the material to rotate, throwing the material toward the bucket ring. The bucket ring then guides the material upwards for discharge, facilitating screening and discharge.

[0016] 5. The baffle ring is used to block the upper side of the bucket-shaped ring to prevent the material from flying upward. The shell guides the material into the discharge nozzle and discharges it outward through the discharge nozzle, which facilitates centralized discharge. Attached Figure Description
