Embodiment Construction

[0013] A kind of bottle blowing machine blowing needle water cooling circulation device provided by the present invention is described in detail below in conjunction with the accompanying drawings:

[0014] Such as Figure 1 ~ Figure 3 As shown, a blowing needle water cooling circulation device of a bottle blowing machine includes a blowing needle body 1, and an exhaust pipe 2, an air intake pipe 4, a cooling water pipe 5, a blowing needle cutter 7 and a blowing needle head 8 are installed on the inner side of the blowing needle body 1, The blowing needle body 1 is provided with an air inlet 102 , an air outlet 101 , a water inlet 103 and a water outlet 104 . The exhaust pipe 2, the air intake pipe 4 and the cooling water pipe 5 all adopt thin-walled seamless stainless steel pipes. The distance between the air inlet 102 and the water inlet 103 is 30-35mm. The intake pipe 4 is outside the exhaust pipe 2 . The cooling water cavity formed by the cooling water pipe 5, the air i...

Abstract

The invention relates to a bottle blowing machine blowing pin water cooled circulating device. The device comprises a blowing pin body, wherein an exhaust pipe, an air inlet pipe, a cooling water pipe, a blowing pin cutter and a blowing pin head are mounted on the inner side of the blowing pin body; an air inlet, an air outlet, a water inlet and a water outlet are formed in the blowing pin body; the device is characterized in that the distance between the air inlet and the water inlet is 30 to 35 mm; the air inlet pipe is formed on the outer side of the exhaust pipe; a cooling water cavity comprising the cooling water pipe, the air inlet pipe, the blowing pin body and the blowing pin head is led to the blowing pin head, is sealed through an upper part O-shaped sealing ring, a middle O-shaped sealing ring and a lower part O-shaped sealing ring, and is isolated through an air cavity, the device can form a good cooling circuiting loop, and can keep a blowing pin at low temperature, thereby ensuring that the blowing pin and a bottle blank form large temperature difference, preventing the blowing pin from being adhered to a bottleneck, and further being capable of improving the production quality and the production efficiency of bottles.

Description

Technical field [0001] The invention belongs to the technical field of a blowing needle cooling device of a blow molding machine, and in particular relates to a blowing needle water cooling cycle device of a blow molding machine. Background technique [0002] The blowing needle needs to be cooled during the working process. The purpose of cooling is to form a significant temperature difference between the blowing needle and the plastic hollow container. Otherwise, when the blowing needle withdraws from the plastic hollow container, it will stick to the mouth of the plastic hollow container. , affecting the quality of plastic hollow containers. [0003] There are some deficiencies in the existing blowing needle cooling device: [0004] The Chinese patent whose patent application number is 200620063331 discloses a blow molding machine blowing device, which includes a drive cylinder and a support plate for installing the drive cylinder. The support plate is provided with a sup...
