Description

Technical Field

[0001] This utility model relates to the field of glass bottle production, and in particular to a furnace front heating device for an annealing furnace that is easy to adjust. Background Technology

[0002] In existing large-scale glass bottle production lines, the formed glass bottles are typically transported to an annealing furnace via a mesh belt conveyor for annealing. However, due to the distance between the forming equipment and the annealing furnace, and the influence of ambient temperature and airflow within the workshop, the formed glass bottles often experience excessively rapid cooling during transport on the mesh belt conveyor. This results in their actual temperature before entering the annealing furnace being far lower than the ideal furnace entry temperature required by the process. Therefore, the current main approach is to add a combustion heating device to the mesh belt conveyor before the annealing furnace entrance to heat the glass bottles. For example, CN201710563709.6 discloses a stress annealing method and system for glass bottles, in which a heater is installed on the conveyor belt between the bottle forming unit and the annealing furnace to heat the glass bottles, ensuring that they enter the annealing furnace at the ideal temperature and guaranteeing the production quality of the glass bottles.

[0003] Existing heaters mainly use simple brackets to fix the nozzles to one or both sides of the conveyor belt, and heat the glass bottles by the flames emitted from the nozzles. This method of fixing the nozzles with simple brackets cannot heat glass bottles of different heights on the conveyor belt. Therefore, multiple simple brackets of different heights are needed to install nozzles of different heights to meet the heating needs of glass bottles of different heights. This results in high installation costs, and when the nozzles need to be adjusted, the adjustment operation is time-consuming and laborious.

[0004] Based on this, this application provides a furnace front heating device for an annealing furnace that can meet the heating needs of glass bottles of different heights and allows for convenient adjustment of the nozzle position and height to solve the above problems. Utility Model Content

[0005] This invention aims to solve the technical problems existing in the prior art. Therefore, this invention provides an easily adjustable heating device for the front of an annealing furnace, which can conveniently adjust the position and height of the nozzle to meet the heating needs of glass bottles of different heights, and the adjustment is time-saving, labor-saving, simple, and quick.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An easily adjustable annealing furnace front heating device is provided, installed on the side of a mesh belt conveyor, for heating glass bottles on the conveyor belt. It includes a fixed base, a column on top of the fixed base, a movable base movably mounted on the column, a rotating shaft rotatably mounted on the movable base, a mounting rod on the rotating shaft, and multiple nozzles movably mounted on the mounting rod. The movable base has a bushing, and a bearing is mounted on the bushing. The rotating shaft consists of a shaft head and a shaft rod. The end face of the shaft head connecting to the shaft rod has a groove, which is fitted to the outer ring of the bearing. The shaft rod passes through the bushing and through the movable base and the column, and a handle nut for locking the rotating shaft is screwed onto the shaft rod. A locking bolt is also provided on the side of the movable base adjacent to the bushing. The column has an adjustment groove along its length.

[0008] In some alternative embodiments, the end of the shaft head is provided with a positioning groove, and the middle part of the mounting rod is fixedly installed in the positioning groove by screws.

[0009] In some alternative embodiments, the end of the shaft may also be detachably fitted with a handle parallel to the mounting rod for controlling the rotation of the shaft.

[0010] In some optional embodiments, the upper and lower surfaces of the mounting rod are provided with sliding grooves, and multiple nozzle mounting seats are provided on the sliding grooves. The nozzle mounting seats are fixed to the mounting rod by locking screws. The top of the nozzle mounting seat is provided with an air inlet connector, and the side is provided with an air outlet interface that is screwed to the nozzle. The air inlet connector is provided with an air inlet valve.

[0011] In some alternative embodiments, the mounting base is made of channel steel, the column is welded to a side plate on one side, and fastening bolts are screwed onto the side plate on the other side.
