Embodiment Construction

[0012] Such as figure 2 As shown, the preform sleeve joint 11 for the bottle blowing machine of the present invention has a structural composition including a base 111 and an expansion sleeve 113 sleeved on the outside of the base. The base is provided with an elastic O-shaped sealing ring 112 sandwiched between the base 111 and the expansion sleeve 113, and the base 111 is locked to the main structure of the bottle blowing machine by a screw. In particular, at least one layer of wear-resistant and self-lubricating polyether ether ketone film 115 is provided on the outer surface of the expansion sleeve 113 . Since this part is mainly in contact with the mouth of the preform, it must be coated with a polyether ether ketone film.

[0013] In addition, since the outer contour surface of the base is also likely to be in contact with the bottle mouth of the preform during the preform socketing process, because the surface is also coated with a layer of polyether ether that is the...

Abstract

The invention discloses a preform sleeve joint for a bottle blowing machine. The structural composition of the sleeve joint includes a base and an expansion sleeve sleeved on the outside of the base. The base is provided with an elastic O-shaped sealing ring, which is sandwiched between the base and the base. Between the expansion sleeves, it is characterized in that a layer of wear-resistant and self-lubricating polyether ether ketone film is provided on the outer surface of the expansion sleeve and the outer contour surface of the base. The application and implementation of the improved socket joint of the present invention, by setting a layer of polyetheretherketone film on the surface of the sleeve joint that is in contact with the inner wall of the preform bottle mouth, can effectively improve the lubrication degree of the preform socket joint, and it is the batch size of the light and thin bottle body. , High yield rate manufacturing provides a guarantee.

Description

technical field [0001] The invention relates to a bottle blowing machine equipment, in particular to a joint device for a fully automatic rotary bottle blowing machine for socketing preforms for blowing. Background technique [0002] When using a bottle blowing machine to blow the preform into the bottle body required by the specification design, the preform needs to be heated first, and then blown into shape through a high-pressure air source combined with the bottle mold, and the preform is heated in the heating furnace It is fixed in the air by the sleeve joint. Such as figure 1 As shown, the sleeve joint 11 is one of the partial structures of the bottle blowing machine 1 integrally connected by guide rails. The fixing principle is: the sleeve joint 11 slides down along the guide rail, and is inserted into the bottle mouth of the preform. Due to the joint action of the elastic sealing ring and the expansion sleeve, the preform is fixed on the sleeve joint 11, and the he...
