Description

Technical Field

[0001] The utility model relates to the technical field of bottle making equipment, in particular to a fire head used for bottoming process of piped bottles. Background Art

[0002] In the process of completing bottle making by using bottle making equipment, it is necessary to complete the breaking of the glass tube into the required length of the bottle product at the breaking station of the bottle making equipment.

[0003] When the bottle making equipment completes breaking the glass tube into the required length at its breaking station, it is usually necessary to preheat the glass tube and then break it after preheating; this makes it easy to form a sealing structure at the breaking point of the glass tube due to the preheating extension. A fire head device is usually provided on the bottle making equipment, and the flame output end of the fire head device is arranged opposite to the breaking point of the glass tube. The flame formed by the fire head device is used to pierce the sealing structure formed at the breaking point of the glass tube due to the preheating extension.

[0004] The existing burners (such as the patent with publication number CN217868622U) have the following disadvantages when in use: 1. The ignition gas path and the primer gas path share an air inlet, so the flame sizes of the two paths cannot be controlled separately; 2. When in use, the primer is prone to flameout and flying fire. Utility Model Content

[0010] Furthermore, the primer air inlet portion is a first air inlet hole coaxially arranged in the flame section, and a second air inlet hole connected to the first air inlet hole is provided in the middle of the fire core.

[0011] Furthermore, the ignition air inlet portion is a plurality of third air inlet holes evenly distributed on the flame section.

[0012] Furthermore, a plurality of air inlet grooves are evenly distributed on the flame section, and an ignition air inlet portion is formed between the air inlet grooves and the outer sleeve.

[0013] Furthermore, an air intake cavity is formed between the outer sleeve and the connecting section, and the air intake cavity is communicated with the ignition air intake portion and the ignition air intake port respectively.

[0014] Furthermore, the second air inlet hole is communicated with the primer air inlet port.

[0015] Furthermore, the pilot fire air inlet and the primer fire air inlet are both arranged on the supporting section.

[0016] Furthermore, the cross section of the support segment is a regular hexagon.
