Vibration can prevent foam particles from standing still and affecting the cooling speed and adhesion. At the same time, vibration screening can also be used, so that the material taken out from the discharge port has undergone preliminary screening. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A packaging foam maturation silo comprises a maturation box 1, a hanging plate 2 is movably mounted on the upper end of the interior of the maturation box 1, a first sieve plate 3 and a second sieve plate 4 are sequentially arranged at the bottom end of the hanging plate 2 from top to bottom, and a vibration assembly is arranged between the first sieve plate 3 and the second sieve plate 4; a servo motor 5 is fixedly mounted on one side of the top of the maturation box 1, a worm 6 is arranged on the output shaft of the servo motor 5, a worm wheel 7 is movably mounted on one side of the maturation box 1 close to the worm 6, a gear 8 is arranged on one side of the worm wheel 7, and a gear ring 9 meshing with the gear 8 is arranged on one side of the hanging plate 2 A first hanger 10 is fixedly installed at the top of the inner side of the maturation box 1 near the servo motor 5. The first hanger 10 is movably connected to the hanging plate 2 through a rotating shaft. The hanging plate 2 is fixedly connected to the four corners of the first sieve plate 3 through a first elastic plate 11, and the first sieve plate 3 is fixedly connected to the four corners of the second sieve plate 4 through a second elastic plate 12. A through groove 22 is provided in the middle of the hanging plate 2, and a feeding port 23 is provided at the upper end of the maturation box 1 near the through groove 22. Two unloading ports 24 are sequentially provided from top to bottom on the side of the maturation box 1 away from the servo motor 5.

[0027] In this embodiment, when unloading, the servo motor 5 is started, the servo motor 5 controls the worm 6 to rotate, the worm 6 drives the worm wheel 7 to rotate, and the worm wheel 7 drives the gear ring 9 on one side of the hanging plate 2 to flip downward through the gear 8. When the gear ring 9 flips down, the hanging plate 2 drives the first screen plate 3 and the second screen plate 4 to flip synchronously through the first elastic plate 11 and the second elastic plate 12, and then the foam particles thereon slide off from one side. In this way, no residue will be generated when unloading, and the unloading speed is faster.

[0028] like Figure 2 As shown, the vibration assembly includes a double-shaft motor 13, an eccentric wheel 14, a connecting rod 15 and a fixed block 16. The double-shaft motor 13 is fixedly installed on the left upper end of the first sieve plate 3, and the eccentric wheels 14 are arranged at both ends of the double-shaft motor 13. The fixed blocks 16 are fixedly installed at both ends of the side of the second sieve plate 4 away from the double-shaft motor 13, and the fixed block 16 is movably connected to the eccentric wheel 14 through the connecting rod 15;

[0029] In this embodiment, during processing, foam particles fall onto the first screen plate 3, and then the dual-axis motor 13 is started. The dual-axis motor 13 controls the rotation of the eccentric wheel 14. When the eccentric wheel 14 rotates, the second screen plate 4 is driven to swing through the connecting rod 15. In this way, the first screen plate 3 and the second screen plate 4 will vibrate in different directions, so that small-volume particles on the first screen plate 3 fall onto the second screen plate 4. Vibration can prevent foam particles from standing still, which affects the cooling speed and adhesion. At the same time, vibration screening can also be used, so that the material taken out from the discharge port 24 has undergone preliminary screening.

[0030] like Figure 3 As shown, a second hanger 17 is provided on the right side of the top of the interior of the ripening box 1, an electric push rod 18 is fixedly installed on the outside of the bottom end of the second hanger 17, and a stop rod 19 is fixedly installed on the output shaft of the electric push rod 18;

[0031] In this embodiment, when the hanger plate 2 is flipped up and reset, the electric push rod 18 at the bottom end of the second hanger 17 is started. The electric push rod 18 controls the blocking rod 19 to push forward and then support it below the right bottom end of the hanger plate 2. In this way, the structural stability of the hanger plate 2 is higher during vibration.

[0032] like Figure 2 As shown, both sides of the maturation box 1 close to the first sieve plate 3 and the second sieve plate 4 are movably mounted with a stopper 21 through a spring 20, and the end of the stopper 21 away from the spring 20 is a semicircular structure;

[0033] In this embodiment, when the first sieve plate 3 and the second sieve plate 4 vibrate, the blocks 21 on both sides are elastically matched through the springs 20, so that when the first sieve plate 3 and the second sieve plate 4 vibrate, the foam particles will not fall from both ends, and when the angle is flipped, the blocks 21 can be retracted to one side through the springs 20.

[0034] Working principle: During processing, foam particles fall onto the first sieve plate 3, and then the dual-axis motor 13 is started, and the dual-axis motor 13 controls the rotation of the eccentric wheel 14. When the eccentric wheel 14 rotates, the second sieve plate 4 is driven to swing through the connecting rod 15, so that the first sieve plate 3 and the second sieve plate 4 will vibrate in different directions, so that the small-volume particles on the first sieve plate 3 fall onto the second sieve plate 4. When unloading, the servo motor 5 is started, and the servo motor 5 controls the rotation of the worm 6, and the worm 6 drives the worm wheel 7 to rotate. The worm wheel 7 drives the gear ring 9 on one side of the hanging plate 2 to flip downward through the gear 8. When the gear ring 9 flips down, the hanging plate 2 drives the first sieve plate 3 and the second sieve plate 4 to flip synchronously through the first elastic plate 11 and the second elastic plate 12, and then the foam particles thereon slide off from one side.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
