Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a multi-layer screening machine for processing plastic granules. Background Technology

[0002] In the later stages of plastic pellet production, the cut plastic pellets often cannot guarantee completely uniform size. As plastic products become more refined, there are often requirements for the size of the raw plastic pellets, which necessitates screening. Existing screening machines generally only perform two-stage screening, and different screening machines or secondary screening are often required for different particle size requirements, resulting in low screening efficiency. Therefore, we propose a multi-layer screening machine for plastic pellet processing to solve the above problems. Utility Model Content

The bottom ends of the upper slide rails are fixedly connected to transmission slide frames. An eccentric wheel slides against the transmission slide frame. The output shafts of the dual-output shaft motors are fixedly connected to the eccentric end face of one end face of the eccentric wheel.

[0005] The transmission connecting rod is hinged to a support base in the middle. The support base is fixedly connected to the top side of the support bar. The bottom two ends of the support bar are respectively fixedly connected to support frames. The two sides of the transmission shaft are respectively hinged to one end of the lower connecting rod. The other end of the lower connecting rod is respectively hinged to one end face of the middle screen. The two ends of the middle screen are respectively slidably connected to the lower slide rail. The top of the middle of the lower slide rail is fixedly connected to the bottom outer wall of the transmission slide frame. The bottom of the middle screen is provided with a lower screen fixedly connected to the support frame.

It includes two symmetrically arranged support frames 1. A dual-output shaft motor 2 is fixedly installed inside the top of each support frame 1. The output shafts of the dual-output shaft motor 2 are fixedly connected to one end of a driving connecting rod 3. The other end of the driving connecting rod 3 is hinged to one end of a driven connecting rod 4. The other end of the driven connecting rod 4 is hinged to both ends of a transmission shaft 5. One end of a transmission connecting rod 6 is hinged to the middle of the transmission shaft 5. The other end of the transmission connecting rod 6... One end of the hinged connecting rod 9 is hinged to the middle of one end of the upper screen 10. The bottom two ends of the upper screen 10 are slidably connected to the upper slide rail 11. The bottom of the upper slide rail 11 is slidably sleeved with the support slide frame 15. The support slide frame 15 is fixedly connected to the opposite end face of the top of the support frame 1. The bottom end of the upper slide rail 11 is fixedly connected to the transmission slide frame 16. The transmission slide frame 16 slides against the eccentric wheel 17. The output shaft of the dual output shaft motor 2 is fixedly connected to the eccentric end face of the eccentric wheel 17.

[0019] The middle of the transmission connecting rod 6 is hinged to the support seat 7. The support seat 7 is fixedly connected to the top side of the support bar 8. The bottom two ends of the support bar 8 are respectively fixedly connected to the support frame 1. The two sides of the transmission shaft 5 are respectively hinged to one end of the lower connecting rod 18. The other end of the lower connecting rod 18 is respectively hinged to one end face of the middle screen 12. The two ends of the middle screen 12 are respectively slidably connected to the lower slide rail 14. The top of the middle of the lower slide rail 14 is fixedly connected to the bottom outer wall of the transmission slide frame 16. The bottom of the middle screen 12 is provided with a lower screen 13 fixedly connected to the support frame 1.

[0020] The dual-output shaft motor 2 is connected to the mains power supply, providing power for its operation. When energized, the dual-output shaft motor 2 drives the active connecting rod 3 to rotate circumferentially. The active connecting rod 3 then drives the hinged driven connecting rod 4 to swing, which in turn drives the hinged transmission shaft 5 to reciprocate. The transmission shaft 5 drives the centrally hinged transmission connecting rod 6 to reciprocate around the support base 7. The transmission connecting rod 6 further drives the end-hinged connecting rod 9 to move, causing the hinged upper screen 10 to move towards... Figure 2 As shown, the movement to the right is simultaneously caused by the transmission shaft 5 driving the hinged lower connecting rod 18 to swing. The lower connecting rod 18 then drives the hinged middle screen 12 to move on the lower slide rail 14, with the middle screen 12 facing towards... Figure 2As shown, the leftward movement causes the middle screen 12 and the upper screen 10 to move in staggered linear motion, thus screening the plastic granules. Simultaneously, the dual-output shaft motor 2 drives the fixed eccentric wheel 17 to rotate circumferentially. The eccentric wheel 17 slides against the transmission slide frame 16, causing the transmission slide frame 16 to move up and down as it rotates. The transmission slide frame 16 then drives the fixed upper slide rail 11 to reciprocate up and down. The T-shaped upper slide rail 11 is supported and limited by the support slide frame 15, enabling the upper slide rail 11 to reciprocate up and down. The upper slide rail 11 drives the sliding connecting... The upper screen 10 reciprocates up and down, while the transmission slide frame 16 drives the fixed lower slide rail 14 to reciprocate up and down. The lower slide rail 14 and the upper slide rail 11 reciprocate up and down synchronously, which in turn drives the middle screen 12 and the upper screen 10 to reciprocate up and down while moving in a reciprocating linear motion, further improving the screening effect. The screened plastic particles finally pass through the fixed lower screen 13, and the plastic particles undergo multi-layer screening, so that multiple plastic particle products of different particle sizes can be screened at one time, improving the screening efficiency.

[0021] Example 2

[0022] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the support bar 8 is fixedly disposed between the transmission shaft 5 and the support frame 1, and the support bar 8 supports the fixing of the support seat 7.

[0023] Specifically, the upper slide rail 11 has a T-shaped structure, and the lower slide rail 14 has an inverted T-shaped structure. The T-shaped upper slide rail 11, together with the sliding support frame 15, enables the upper slide rail 11 to perform reciprocating linear lifting and lowering work. At the same time, the lower slide rail 14 is set opposite to the upper slide rail 11 to provide sliding support for the middle screen 12.

[0024] Specifically, the transmission slide frame 16 has a racetrack-shaped structure. The transmission slide frame 16 and the eccentric wheel 17 slide against each other. When the eccentric wheel 17 rotates in a circle, the transmission slide frame 16 is moved by the contact.

[0025] Specifically, the upper screen 10, the middle screen 12, and the lower screen 13 are arranged sequentially from top to bottom, with the areas of the upper screen 10, the middle screen 12, and the lower screen 13 increasing sequentially, so that the middle screen 12 can completely cover the upper screen 10, and the lower screen 13 can completely cover the middle screen 12.

[0026] Specifically, support frame 1 has an inverted T-shaped structure, and support bar 8 has a U-shaped structure.

[0027] Example 3

[0028] Reference Figure 1-3This is the third embodiment of the present invention. Based on the above two embodiments, in use, the dual-output shaft motor 2 is connected to mains power, providing operating power. When energized, the dual-output shaft motor 2 drives the active connecting rod 3 to rotate circumferentially. The active connecting rod 3 drives the hinged driven connecting rod 4 to swing, which in turn drives the hinged transmission shaft 5 to reciprocate. The transmission shaft 5 drives the centrally hinged transmission connecting rod 6 to reciprocate around the support base 7. The transmission connecting rod 6 then drives the end-hinged hinged connecting rod 9 to move, causing the hinged upper screen 10 to move towards... Figure 2 As shown, the movement to the right is simultaneously caused by the transmission shaft 5 driving the hinged lower connecting rod 18 to swing. The lower connecting rod 18 then drives the hinged middle screen 12 to move on the lower slide rail 14, with the middle screen 12 facing towards... Figure 2 As shown, the leftward movement causes the middle screen 12 and the upper screen 10 to move in staggered linear motion, thus screening the plastic granules. Simultaneously, the dual-output shaft motor 2 drives the fixed eccentric wheel 17 to rotate circumferentially. The eccentric wheel 17 slides against the transmission slide frame 16, causing the transmission slide frame 16 to move up and down as it rotates. The transmission slide frame 16 then drives the fixed upper slide rail 11 to reciprocate up and down. The T-shaped upper slide rail 11 is supported and limited by the support slide frame 15, enabling the upper slide rail 11 to reciprocate up and down. The upper slide rail 11 drives the sliding connecting... The upper screen 10 reciprocates up and down, while the transmission slide frame 16 drives the fixed lower slide rail 14 to reciprocate up and down. The lower slide rail 14 and the upper slide rail 11 reciprocate up and down synchronously, which in turn drives the middle screen 12 and the upper screen 10 to reciprocate up and down while moving in a reciprocating linear motion, further improving the screening effect. The screened plastic particles finally pass through the fixed lower screen 13, and the plastic particles undergo multi-layer screening, so that multiple plastic particle products of different particle sizes can be screened at one time, improving the screening efficiency.
