Description

Technical Field

[0001] The utility model relates to the technical field of particle screening, in particular to a PE particle screening device. Background Art

[0002] PE particles are thermoplastic materials commonly used in our daily lives. Environmentally friendly modified PE particles refer to general plastics and engineering plastics that are processed and modified through filling, co-blending and reinforcement to improve flame retardancy, strength, etc. A screening device is required during processing.

[0003] The existing screening device has the following problems when in use:

[0004] (1) The filter is fixed and can only filter particles of a single size. It is troublesome to replace the filter.

[0005] (2) Through vibration screening, the entire device is subjected to vibration, and wearing parts are easily damaged after long-term use. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a PE particle screening device to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a PE particle screening device, comprising a machine base and a support frame fixed to the surface of the machine base, a fixed cylinder for placing particles fixedly connected to the surface of the support frame, a movable cylinder connected to the bottom of the fixed cylinder via an elastic connecting section, winding rollers driven by a motor are rotatably connected to both sides of the support frame, and a filter screen is transmission-connected to the surfaces of the two winding rollers, and the filter screen is composed of multiple filter sections with gradually decreasing calibers from large to small;

[0008] The filter screen is fixedly connected with the surface of the movable cylinder with a telescopic cylinder, and one end of the piston rod of the telescopic cylinder is fixedly connected with an extrusion sleeve, and the filter screen passes through the extrusion sleeve and the movable cylinder, and the top of the extrusion sleeve is provided with a groove adapted to the bottom of the movable cylinder. The side of the support frame is rotatably connected with a cam driven by a rotating motor. When in use, the two winding rollers are driven to rotate according to the use requirements, and the filter section of the required caliber is driven to rotate to the bottom of the movable cylinder. After the rotation is completed, the extrusion sleeve moves upward under the drive of the telescopic cylinder, and can squeeze the filter screen so that it is attached to the bottom of the movable cylinder to screen the particles. At this time, the two winding rollers both release a section of the filter screen, and then the particles are added to the inside of the fixed cylinder. The movable cylinder is then hit by the rotation of the cam, and the movable cylinder vibrates, driving the filter screen to vibrate and screen the particles inside. The vibration can be buffered by the setting of the elastic connecting section, and no vibration is caused to other components. Moreover, filters of different mesh sizes can be selected for screening and separation according to the use requirements, and the scope of application is wider.

[0009] As a further solution of the present invention: the rotation trajectory of the cam coincides with the surface of the movable cylinder, and the cam can impact the movable cylinder through rotation, causing it to vibrate left and right to screen the particles inside through the filter.

[0010] As a further solution of the present invention: the extrusion sleeve is hollow, and a plurality of extrusion nets arranged in a circular array are fixedly connected to the bottom. The extrusion sleeve moves upward under the drive of the telescopic cylinder, and can squeeze the filter net so that it is attached to the bottom of the movable cylinder to screen the particles. Moreover, through the setting of the extrusion net, the filter net can be ensured to maintain a horizontal state to prevent the sieve holes from deformation.

[0011] As a further solution of the present invention: the inner cavity of the machine base is provided with a discharge port located below the movable cylinder, and the particles screened by the movable cylinder are discharged through the discharge port.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When in use, the two winding rollers are driven to rotate according to the use requirements, and the filter section of the required caliber is driven to rotate to the bottom of the movable cylinder. Filters of different mesh sizes can be selected for screening and separation according to the use requirements, which has a wider range of applications.

[0014] (2) The cam rotates to hit the movable cylinder, which vibrates and drives the filter to vibrate to screen the particles inside. The elastic connection section can buffer the vibration and will not cause vibration to other parts. BRIEF DESCRIPTION OF THE DRAWINGS
