Description

Technical Field

[0001] The utility model relates to the technical field of modified plastic production, in particular to an anti-clogging screening device for modified plastic particle mixing. Background Art

[0002] Modified plastics, intermediate products in the petrochemical industry chain, are plastic products that are processed through methods such as filling, blending, and reinforcement based on general-purpose and engineering plastics to improve their flame retardancy, strength, impact resistance, and toughness. Screening devices are required during plastic processing.

[0003] Existing anti-clogging screening devices for modified plastic particle mixtures usually include a screen plate and a vibration motor, which work together to screen the plastic particles. However, the existing screening devices do not have an anti-clogging mechanism for the plastic particles. The screen plate will gradually become clogged after long-term use, thereby reducing the screening rate and screening quality of the plastic particles and reducing the practicality of the screening device during use. Therefore, there is a need for an anti-clogging screening device for modified plastic particle mixtures. Utility Model Content

A motor 16 with an output end connected to the threaded rod 14 is installed at the left end of the screening box 1.

[0028] In combination with the above structure, when the horizontal moving component 8 is in use, the motor 16 drives the threaded rod 14 to rotate, so that the slider 15 slides in the slide groove 1301, thereby driving the blowing component 9 and the scraping component 10 to move horizontally.

[0029] Combined with attachment Figure 2 The blowing assembly 9 includes a hollow plate 17 fixed to the front end of the slider 15, and a plurality of exhaust pipes 18 are respectively provided at the upper and lower ends of the hollow plate 17.

[0037] The threaded rod 14 is driven to rotate by the horizontal moving component 8, i.e., the motor 16, so that the slider 15 slides in the slide groove 1301, thereby driving the blowing component 9 and the scraping component 10 to move horizontally; the air flow is delivered by the external air pump through the telescopic hose 19 of the blowing component 9 into the hollow plate 17, and is discharged through a number of exhaust pipes 18 at the upper and lower ends of the hollow plate 17, so that the strong air flow blows to the pair of inclined screen plates 6, so that the blocked holes of the pair of inclined screen plates 6 are penetrated; the connecting plate 23 in the scraping component 10 drives the connecting rod 24 to move horizontally, and the springs 26 wound around the upper and lower ends of the connecting rod 24 are used to keep the pair of brush plates 25 in contact with the inclined screen plates 6, so that the blocked holes of the pair of inclined screen plates 6 are penetrated, thereby improving the screening rate and screening quality of plastic particles and improving the practicality of the screening device when in use.
