Description

Technical Field

[0001] The present application relates to the field of foam molding machine design, and in particular to a plastic temporary storage device for a foam molding machine. Background Art

[0002] Foam plastic machinery is a mechanical equipment used to manufacture polystyrene foam plastic boards, and the products produced can be used as external insulation materials for buildings.

[0003] Since a batch of injection molding usually requires a lot of plastic, a large amount of plastic particles need to be temporarily stored in a temporary storage device for use. Usually, a structure is adopted in which a pipe and an air suction fan are connected to a tank. The air suction fan sucks the plastic particles in the external device and then sends them into the tank through the pipe for temporary storage. Since the plastic particles are usually small in diameter, they are easy to remain in the air suction fan. The impeller and other parts of the air suction fan are easily blocked by plastic particles, resulting in a decrease in suction force. Even too many plastic particles hitting the impeller may cause damage to the precision impeller. Frequent cleaning of the air suction fan and replacement of the impeller will lead to a decrease in production efficiency and an increase in production costs. Summary of the invention

[0030] Reference Figure 1-5 ,

[0031] A temporary storage device for plastics of a foam molding machine comprises: a storage tank 1, a sieve plate 2, an air suction pipe 3, an air suction fan 4, a feed pipe 5 and a discharge control device 6. The storage tank 1 forms a first interface, a second interface and a third interface. The air suction fan 4 uses an existing vacuum suction machine, one end of the feed pipe 5 is connected to the second interface, and the other end of the feed pipe 5 is connected to an external feeding device. The air suction end of the air suction fan 4 is connected to one end of the air suction pipe 3, and the other end of the air suction pipe 3 is connected to the first interface. After the air suction fan 4 is started, the gas in the storage tank 1 is sucked out through the air suction pipe 3, the air pressure in the storage tank 1 is reduced, and the plastic particles in the external feeding device enter the storage tank 1 through the feed pipe 5 under atmospheric pressure. The first interface and the second interface are formed together at the upper part of the storage tank 1, so that most of the plastic particles entering the storage tank 1 from the feed pipe 5 fall downward into the storage tank 1 under the action of gravity, and avoid entering the first interface. The first interface is covered with a sieve plate 2 to prevent a small portion of plastic particles from entering the suction pipe 3 when the suction fan 4 sucks air. The third interface is formed at the lower part of the storage tank 1. Under the action of gravity, the plastic particles in the storage tank 1 flow to the third interface, and the third interface is connected to the discharge control device 6, which controls the opening and closing of the third interface.

[0032] Specifically, the storage tank 1 includes: a tank body 11, a column 12, a first pipe joint 13 and a sealing tube 14. The upper and lower ends of the column 12 are both open, and the opening of the lower end of the column 12 extends into the upper part of the tank body 11 to form a first interface. The edge of the sieve plate 2 is fixed to the opening of the lower end of the column 12, and the sieve plate 2 covers the opening of the lower end of the column 12. The column 12 extends out of the side wall of the tank body 11 and is connected to the suction pipe 3. The opening at the upper end of the column 12 is fixed to the lower end of the first pipe joint 13 by bolts. The upper end of the first pipe joint 13 forms an external thread, and the lower end of the closed tube forms an internal thread. The upper end of the first pipe joint 13 and the lower end of the closed tube form a detachable threaded connection. When the worker needs to check and clean the sieve plate 2, the sealing tube 14 is unscrewed from the first pipe joint 13, and the sieve plate 2 can be seen downward through the first pipe joint 13.

[0033] Specifically, the discharging control device 6 includes: a mounting plate 61, a cover plate 62, a second pipe joint 63, a rotating shaft 64 and a rotating assembly. The upper end of the mounting plate 61 is fixedly connected to the third interface by bolts, the cover plate 62 covers the upper end of the mounting plate 61, the mounting plate 61 forms a plurality of first docking interfaces 611 around the axis of the rotating shaft 64, and the second pipe joint 63 docks with the first docking interfaces 611 from the bottom of the mounting plate 61. The cover plate 62 forms a plurality of second docking interfaces 621 around the axis of the rotating shaft 64, and the plurality of first docking interfaces 611 and the plurality of second docking interfaces 621 correspond to each other one by one. The upper end of the rotating shaft 64 passes through the mounting plate 61 and is fixed to the cover plate 62. The rotating assembly is used to rotate the rotating shaft 64. The rotating assembly rotates the rotating shaft 64, and the rotating shaft 64 drives the cover plate 62 to rotate, so that the multiple second docking ports 621 and the multiple first docking ports 611 are aligned one by one, and the third port is opened, so that the plastic particles in the storage tank 1 can flow into the pipe connected to the mold through the second docking ports 621, the first docking ports 611 and the second pipe joint 63. The rotating assembly can also rotate the rotating shaft 64 to stagger the multiple second docking ports 621 and the multiple first docking ports 611, so that the cover plate 62 cooperates with the mounting plate 61 to close the third port.

[0034] Specifically, the rotating assembly includes: a power member 65 and a connecting rod 66. The power member 65 is a cylinder, the outer shell of the power member 65 is hinged to the mounting plate 61 through a pin, the output end of the power member 65 is hinged to one end of the connecting rod 66 through a pin, the other end of the connecting rod 66 forms a longitudinal polygonal hole, and the middle part of the rotating shaft 64 forms a polygonal connecting part, which is inserted into the polygonal hole and fixed. When the output end of the power member 65 is extended to the longest, the connecting rod 66 drives the rotating shaft 64 to rotate, and the rotating shaft 64 aligns the second docking port 621 of the cover plate 62 and the first docking port 611 of the mounting plate 61, thereby opening the third interface. When the output end of the power member 65 is contracted to the shortest, the connecting rod 66 drives the rotating shaft 64 to rotate, and the rotating shaft 64 staggers the second docking port 621 of the cover plate 62 and the first docking port 611 of the mounting plate 61, thereby closing the third interface.

[0035] Specifically, the rotating assembly further includes: a first sleeve 67, a second sleeve 68 and a spring 69. The first sleeve 67 is coaxially sleeved and fixed with the lower end of the rotating shaft 64, the second sleeve 68 is coaxially slidably connected with the middle part of the rotating shaft 64, the upper end of the second sleeve 68 contacts the lower end of the connecting rod 66, the lower end of the second sleeve 68 is fixed with the upper end of the spring 69, the lower end of the spring 69 is fixed with the upper end of the first sleeve 67, and the spring 69 applies an upward force to the second sleeve 68, so that the second sleeve 68 presses the connecting rod 66 upward against the lower end of the mounting plate 61 to prevent the connecting rod 66 from sliding downward when rotating, causing the polygonal hole and the polygonal connecting portion to be separated.

[0036] Specifically, the second pipe joint 63 includes: a first pipe section 631 and a second pipe section 632. An external thread is formed on the upper end of the first pipe section 631, and an internal thread is formed in the first docking port 611. The upper end of the first pipe section 631 and the first docking port 611 form a detachable threaded connection, which facilitates the replacement of the entire second pipe joint 63. The upper end of the second pipe section 632 extends into the lower end of the first pipe section 631 and communicates with the first pipe section 631. The lower end of the second pipe section 632 is used to be sleeved with an external pipe connected to the mold.

[0037] Specifically, the lower end of the first pipe section 631 forms a first slide groove 6311 and a second slide groove 6312, the first slide groove 6311 is perpendicular to the ground, the second slide groove 6312 is parallel to the ground, the lower end of the first slide groove 6311 is connected to the lower end surface of the first pipe section 631, the upper end of the first slide groove 6311 is connected to one end of the second slide groove 6312, and a protrusion 6321 is formed in the middle of the second pipe section 632, and the protrusion 6321 is slidably matched with the first slide groove 6311 and the second slide groove 6312. When worker Ajing installs the second pipe section 632 on the first pipe section 631, it is only necessary to align the protrusion 6321 with the lower end of the first slide groove 6311, push the second pipe section 632 upward until the protrusion 6321 slides out of the first slide groove 6311 to the docking point between the upper end of the first slide groove 6311 and one end of the second slide groove 6312, and then rotate the second pipe section 632 around its own axis and toward the other end of the second slide groove 6312, and the protrusion 6321 slides into the second slide groove 6312, so that the second pipe section 632 is suspended on the first pipe section 631 to complete the docking.
