Technical Field

[0001] The utility model relates to the technical field of engineering plastic particle processing, in particular to size screening equipment for engineering plastics. Background Art

[0002] Engineering plastic particles are a type of plastic that can be used as engineering materials and to replace metal to manufacture machine parts. They have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used for a long time in harsh chemical and physical environments and can replace metal as engineering structural materials.

[0003] Engineering plastic particles need to be size-screened during the processing process in order to classify engineering plastic particles of different sizes. The screen of the existing screening mechanism is usually plate-shaped. In order to ensure the screening effect, the surface area of ​​the screen is large, resulting in a large footprint of the screening mechanism, which is not conducive to improving its flexibility during assembly and movement. Therefore, a size screening device for engineering plastics is proposed to solve the above-mentioned problems. Utility Model Content

[0006] Furthermore, the first outer screen and the second outer screen are both provided with first sieve holes, the first inner screen and the second inner screen are both provided with second sieve holes, and the caliber of the first sieve holes is smaller than that of the second sieve holes.

[0007] Furthermore, the output shaft of the motor passes through the bottom wall of the fuselage and is rotatably connected to the bottom wall of the fuselage. The bottom of the driven cylinder is rotatably connected to the inner bottom wall of the fuselage. A slot is provided inside the driven cylinder, and the driven cylinder can be connected to the driving bar through the slot.

A limit groove is provided on the limit support seat, and a limit rail is provided on the inner bottom wall of the fuselage. The inner bottom wall of the fuselage can be slidably connected to the limit support seat through the limit rail and the limit groove.

[0009] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0010] The size screening device for engineering plastics is used to pour the engineering plastic particles to be screened into the first inner screen, and the first inner screen and the second inner screen, the first outer screen and the second outer screen are spliced ​​together by bolts and nuts. The motor drives the driving bar, the driven cylinder, the first outer screen, the second outer screen, the first inner screen and the second inner screen to rotate, and centrifugal force is generated during rotation to throw the engineering plastic particles to the surroundings.

[0020] A size screening device for engineering plastics includes a body 1, a motor 2 is provided at the bottom of the body 1, a driving bar 3 is fixedly connected to the top of the output shaft of the motor 2, a driven cylinder 4 is movably connected to the outside of the driving bar 3, a first outer screening mesh 5 is fixedly connected to the top of the driven cylinder 4, a second outer screening mesh 6 is fixedly connected to the top of the first outer screening mesh 5 by bolts and nuts, a fixing rod 7 is fixedly connected to the first outer screening mesh 5 and the second outer screening mesh 6, a first inner sub-screen 8 is fixedly connected to the top of the fixing rod 7 on the first outer screening mesh 5, a second inner sub-screen 9 is fixedly connected to the bottom of the fixing rod 7 on the second outer screening mesh 6, and the first inner sub-screen 8 and the second inner sub-screen 9 can be spliced ​​with each other.

[0021] Furthermore, the fuselage 1 plays a role in supporting the device and maintaining the stability of the overall structure of the device. The output shaft of the motor 2 is fixedly connected to the driving bar 3, so that the motor 2 can drive the driving bar 3 to rotate after starting. The driving bar 3 can be connected to the driven cylinder 4 through the slot 401, so that when the driving bar 3 rotates, the driven cylinder 4 can be driven to rotate, and it is convenient for the driven cylinder 4 and the first outer screen 5 to be disassembled and assembled. The driven cylinder 4 is fixedly connected to the first outer screen 5, so that when the driven cylinder 4 rotates, the first outer screen 5 can be driven to rotate.

[0022] Furthermore, the first outer screen 5 can be fixedly connected to the second outer screen 6 by bolts and nuts, and the first outer screen 5 is connected to the first inner screen 8 by a fixing rod 7, and the second outer screen 6 is connected to the second inner screen 9 by a fixing rod 7, so that the first outer screen 5, the second outer screen 6, the first inner screen 8 and the second inner screen 9 can rotate synchronously, and the first outer screen 5, the second outer screen 6, the first inner screen 8 and the second inner screen 9 generate centrifugal force when they rotate, and throw the engineering plastic particles to the surroundings, so that the first sieve holes 5601 and the second sieve holes 8901 on the first outer screen 5, the second outer screen 6, the first inner screen 8 and the second inner screen 9 screen the engineering plastic particles.

[0023] Furthermore, the fuselage 1 is slidably connected to the limiting support seat 11 through the limiting rail 10 and the limiting groove 1101, maintaining the stability of the limiting support seat 11 during the displacement process. The limiting support seat 11 supports the first outer screen 5 and maintains the stability of the first outer screen 5, the second outer screen 6, the first inner screen 8 and the second inner screen 9 during rotation.

The motor 2 drives the driving bar 3, the driven cylinder 4, the first outer screen 5, the second outer screen 6, the first inner screen 8 and the second inner screen 9 to rotate. Centrifugal force is generated during rotation, and the engineering plastic particles are thrown to the surroundings. Since the diameter of the first sieve hole 5601 is larger than that of the second sieve hole 8901, the engineering plastic particles with a diameter larger than the second sieve hole 8901 will be retained in the first inner sieve 8 and In the second inner sieve 9, engineering plastic particles with a diameter smaller than the second sieve hole 8901 and larger than the first sieve hole 5601 will be retained in the space formed by the first outer sieve 5, the second outer sieve 6 and the first inner sieve 8, the second inner sieve 9, and engineering plastic particles with a diameter smaller than the first sieve hole 5601 will pass through the first outer sieve 5 and the second outer sieve 6 and be retained inside the fuselage 1. The first outer sieve 5, the second outer sieve 6, the first inner sieve 8 and the second inner sieve 9 are all in the shape of a hemispherical net, which increases the surface area while reducing the footprint, solving the problems raised in the background technology.
