Description

Technical Field

[0001] The invention relates to the technical field of garbage can production, in particular to an injection molding auxiliary demoulding and stacking device for garbage cans. Background Art

[0002] The materials used to make trash cans are generally plastic, so plastic trash cans are generally produced using injection molding. Injection molding is a commonly used method in plastic molding processing. The process is as follows: powdered or granular plastic is sent from the hopper of the injection machine into the barrel for heating to melt the plastic, reach a flowing state and have good plasticity, and then injected into the mold cavity with a lower temperature through the nozzle at the front end of the barrel under the push of the plunger. After cooling and shaping, the mold is opened to complete the production of the plastic trash can. The barrel body needs to be sucked by a suction cup, and then the barrel body is removed from the injection molding equipment. However, since the weight of the trash can itself is not small, a large negative pressure attraction needs to be provided during the entire separation and transfer process to ensure that the barrel body does not fall.

[0003] However, the currently used trash can transfer equipment is affected by the smoothness of the trash can surface, which makes it difficult to firmly suck the trash can.

[0014] The present invention provides a garbage can injection molding auxiliary demoulding and stacking device, which has the following beneficial effects: 1. The trash can injection molding auxiliary demoulding and stacking device is placed on one side of the demoulding equipment when in use. After the trash can is separated from the mold, it falls into the collecting device, and then the collecting device is driven to move by the electric conveyor belt. When the collecting device moves to a suitable position, the trash can is released to complete the collection and stacking, which is convenient for automatically collecting and stacking the trash cans after demoulding. A limiting base and a limiting card slot are also provided, and the collecting device can cooperate with the limiting card slot on the limiting base, so that the conveying device can simultaneously convey multiple groups of collecting devices and the trash cans processed thereon, thereby realizing assembly line production with high production efficiency.

[0015] 2. The garbage bin injection molding auxiliary demoulding and stacking device is provided with a collecting device. When in use, the collecting device is placed on the conveying device, and the limiting card block is inserted into the limiting card slot. The collecting bracket is fixed to the conveying device through the cooperation of the limiting card block and the limiting card slot. After the garbage bin falls off the demoulding device, it falls into the collecting circle, and then the electric rotating table rotates to drive another group of collecting circles to move to the bottom of the demoulding device for collection again. When the collecting device moves to the stacking position, the small motor drives the collecting circle to rotate, and the collecting circle drives the internal garbage bin to rotate. When the garbage bin mouth faces downward, it can fall out of the collecting circle and fall below under the action of gravity. The same group of collecting devices can collect multiple groups of garbage bins with high collection efficiency, and the collected garbage bins can be stacked.

When the garbage bin falls into the collection circle, the air pump is started, and the air pump sends cold air into the annular air duct, and the annular air duct sends the cold air into the first rotating device. The cold air inside the first rotating device enters the second branch pipe through the first branch pipe and the second rotating device, enters the air outlet nozzle through the second branch pipe, and is discharged from the air outlet nozzle, so as to cool down the garbage bin above and help the garbage bin to be completely cooled, so as to avoid deformation caused by squeezing when the garbage bin is stacked.
