Abstract

The lower chuck of the bottle making machine includes a jaw base, a core tube, and a base, and a fixed-length plane is arranged on the upper surface of the jaw base. The utility model has the advantages that: since the upper surface of the jaw seat has a fixed-length plane, the fixed-length plane can be used as a reference plane for determining the length of the bottle and the length of the tube head at the fixed-length station of the bottle making machine. It can be used as a reference plane for breaking glass bottles, and as a reference plane for secondary length fixing during the bottle making process. In addition, the lower chuck can be directly used as a connecting device. There is a small hole on the fixed-length plane, and the plane on the jaw seat contacts with the bottle mouth end surface of the glass bottle to form a seal after the glass bottle is broken or the second length is fixed, so as to realize the bottom blowing process. Due to the addition of a positioning plate on the base, combined with other components, the vertical position of the lower chuck can be conveniently limited, thereby expanding the application range of the bottle making machine. Because a roller is added on the positioning plate, it is convenient for the lower chuck to move on the guide rail.

Description

Bottom chuck of bottle making machine

technical field

The invention relates to a part of a bottle making machine for controlling glass bottles, in particular to a lower chuck.

Background technique

On the currently used bottle-making machine for controlling glass bottles, the structure of the lower chuck has three types, which are the rotating shaft chuck, the lever chuck and the self-centering chuck. , Jaw seat 2, spring 4, core tube 3, base 9 and force transmission device. The three types of lower chucks all transmit the spring force to the jaw 1, so that the jaw 1 can clamp the glass bottle, but the way of transmitting the spring force is different due to the different force transmission devices, as shown in Figure 1 It is a schematic diagram of the structure of the rotary shaft type lower chuck.

The lower chucks of the above three forms all have a common feature, that is, there is a core tube 3 in the middle of the jaw base 2, and the inner hole of the core tube can accommodate a glass bottle. At the breaking station on the bottle making machine, when the lower chuck is raised to break a longer glass bottle, the bottle mouth and a part of the bottle body of the glass bottle can enter the inside of the jaw seat, while at the bottle output station , the jaws 1 of the lower chuck are loosened, and the finished glass bottle directly enters the inside of the core tube 3, and finally drops the bottle from the bottom of the core tube.

With the development of bottle-making technology, new bottle-making processes have emerged, such as secondary length-fixing process and bottom-blowing process. Among them, the second length determination refers to the second determination of the length of the bottle after the breaking, on the basis of the first determination of the length of the bottle before the breaking, so as to make the length and size of the glass bottle more accurate. The bottom blowing refers to blowing air with a certain pressure into the bottle after breaking the glass bottle to make the bottom of the bottle bulge up, so as to eliminate the defect of uneven thickness of the bottom of the bottle. In addition, in order to make the bottle making machine suitable for bottle lengths and tube head lengths of various specifications, it is necessary to limit the vertical position of the lower chuck. However, the existing lower chuck cannot adapt to these new bottle-making techniques due to its limited structure, and must be improved.
