Description

Technical Field

[0001] The utility model relates to the technical field of plastic product molding preheating devices, in particular to a plastic product molding preheating device. Background Art

[0002] Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material. Plastic product processing includes films, injection molded products, plastic pipes, plastic hollow products, plastic sheet products and foam plastic products. Plastic is a type of synthetic polymer material with plasticity.

[0003] The existing patent CN219988157U discloses a plastic product molding preheating device. When in use, first start the motor 1, the motor 2, the fan and the heating tube, and then pour the plastic raw material onto the surface of the conveyor belt. At this time, the motor 1 is started, and the plastic raw material is transported under the action of the driving roller and the conveyor belt. When the plastic raw material is transported into the preheating box, the fan is started to inhale the air inside the preheating box, and then the air first enters the purification box and is processed by a number of filter plates and water absorption plates. After the processing, the air enters the wind box, and then is heated by the heating tube and the inside of the preheating box is preheated from a number of exhaust holes. When the motor 2 is started, it drives two elliptical rollers to rotate under the transmission action of the belt and the pulley. When the elliptical roller rotates, it drives the conveyor belt to move to make the plastic raw material roll for preheating.

[0004] When the fan blows hot air into the plastic raw materials for preheating, since the plastic raw materials themselves are granular and relatively light, part of the plastic raw materials will be blown to different places during the hot air blowing process, and part of the plastic raw materials cannot be preheated.
