Description

Technical Field

[0001] The utility model relates to the technical field of heating or cooling preforms, parisons or blown products, and particularly relates to a cooling device for PE bottle production. Background Art

[0002] After the production of PE bottles, in order to ensure their shaping and quality, it is often necessary to cool the PE bottles. The Chinese utility model patent, with the authorization announcement number "CN218660094U", discloses a cooling device for plastic bottle production, which relates to the technical field of plastic bottle production. It includes a base, on the top of which a box body is installed, and a ventilation net is embedded in the center of the top surface of the box body. Two sides at the bottom of the ventilation net are provided with fans, and a spray head is arranged below the fans. The center of the top of the spray head is connected with a motor. Water outlet holes are formed on both sides inside the spray head, and a filter net is connected inside the water outlet holes. A sealing bearing is embedded in the center of the bottom of the spray head, a conduit is connected inside the sealing bearing, and a water pump is installed at the bottom end of the conduit.

[0003] The above technical solution pumps the cooling water inside the box body through the water pump, transmits it into the inside of the spray head through the conduit, sprays it out through the water outlet holes after being filtered by the filter net, and cools the plastic bottles placed above the bearing net. The waste water after cooling the plastic bottles can pass through the bearing net and filter into the lower part inside the box body to form a water cycle, which is relatively water-saving. When cooling different-shaped PE bottles, for example, when cooling a pear-shaped PE bottle, if the cylindrical cooling method is still adopted and water is sprayed at equal intervals for heat dissipation, due to the uneven surface of its pear shape, spraying water with a constant-distance spray head for cooling will ultimately result in uneven cooling of the surface of the pear-shaped PE bottle, causing uneven deformation and increasing the number of defective products. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a cooling device for PE bottle production, which can solve the problem that when cooling a pear-shaped PE bottle with an uneven surface by spraying water with a spray head at a constant distance, it will ultimately result in uneven cooling of the surface of the pear-shaped PE bottle, causing uneven deformation and increasing the number of defective products.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cooling device for PE bottle production, including a cooling housing;

[0006] The spraying assembly is arranged on the cooling housing. The spraying assembly includes an electric telescopic rod I, a connecting plate I and a spraying head.

The connecting plate I is fixedly sleeved on the spraying head. The number of the blowing assemblies is three, and all three blowing assemblies are arranged on the cooling housing;

[0007] The clamping assembly is arranged inside the cooling housing. The clamping assembly includes a clamping disc, a support base, a rotating shaft I and a rod. The rotating shaft I rotates inside the cooling housing. The support base is welded to the upper end of the rotating shaft I, and the clamping disc is fixed on the rod.

[0008] Preferably, a lower gear I is fixedly sleeved on the surface of the rotating shaft I, and a rotating shaft II is rotatably connected inside the cooling housing.

At the same time, the clamping assembly drives different-shaped PE bottles to rotate, cooperating with the spraying assembly, so as to cool the entire PE bottle more evenly, avoiding continuous spraying on a certain part of the PE bottle, resulting in too fast temperature drop and too large overall temperature difference of the PE bottle, and the phenomenon of surface hardness decrease. That is, under the combined action of the spraying assembly and the clamping assembly, different-shaped PE bottles can be cooled evenly, ensuring the shape and surface strength of the PE bottle and reducing the defective rate.
