Technical Field

The invention relates to the field of bottle blowing and filling equipment, in particular to a bottom die device for bottle blowing and filling.

Background

The bottom die device for blowing hot filling bottles mainly comprises a cylinder body, a bottom die, a piston and other parts. The cylinder body pushes the piston to reciprocate by alternately air intake and exhaust, so that the bottom die is pushed up and retracted. The bottom die device needs to be installed on a supporting device of the base, and due to the fact that the air cylinder needs to reciprocate up and down, great impact force can be caused to the supporting device, and the supporting device and the bottom die device need to be firmly connected together. Given the productivity of current machines, the same machine must have a certain versatility to accommodate the different types of bottles that may vary in production capacity and format, and the mould devices for bottle forming must in turn be provided with easy removal and disassembly.

The existing bottom die supporting structure comprises a clamping device provided with a mounting hole, a locking structure is arranged in the hole of the clamping device, the clamping device is mounted on a support, the clamping device slides up and down by mounting a guide rail slide block on the support, and the guide rail slide block is mounted on a base to support the clamping device to slide. The cylinder device for driving the bottom die is structurally characterized in that the bottom die is arranged on the upper portion of the cylinder device, a pin is arranged at the bottom of the cylinder device and inserted into a hole of the clamping device, and the cylinder device is locked on the supporting structure through the locking structure, so that the bottom die portion of the whole bottle blowing die is formed. According to the structure, due to the fact that the installation depth of the bottom of the air cylinder is limited, the bolt can only be installed on the surface layer of the bottom of the air cylinder device, the bolt is prone to loosening, and the air cylinder device is prone to damage in the vertical reciprocating motion. In addition, because the aperture size of mounting hole needs to cooperate with the bolt, in the installation, be difficult to once only aim at the mounting hole with the bolt, it is inconvenient to install the time-consuming.

Detailed Description

As shown in fig. 1-4, a bottom die device for a blow-heating bottle includes a cylinder device 2 and a support 3, the top of which is provided with a bottom die 1, the cylinder device includes a cylinder body 21, a cylinder end cover 22 at the bottom of the cylinder body and a piston 23 reciprocating inside the cylinder body, the upper part of the piston fixes a heating body 25 for heating the bottom die through a support shaft 24, the lower end of the piston is provided with a cylinder shaft 4 penetrating through the cylinder end cover, the cylinder shaft and the support shaft are hollow and mutually communicated, the cylinder end covers at two sides of the cylinder shaft are provided with clamping sleeves 5, the inner side edges of the clamping sleeves are provided with buckles 51, and the lower end of the cylinder end cover is also provided with; the upper portion of the support 3 is provided with a positioning boss 31 matched with the positioning spigot 6, the supports on the two sides of the positioning boss are provided with clamping devices 7 inserted into the clamping sleeves, each clamping device comprises a cylinder 71, a movable piece 72 is embedded in the side wall of the cylinder, and a clamping shaft 73 which can upwards push the movable piece to protrude out of the outer surface of the side wall of the cylinder to clamp the buckle is arranged in the cylinder. After the external cam mechanism drives the support to reach an upper position, the left side and the right side of the mold body are transversely combined to clamp the cylinder device, so that the mold body and the bottom mold are surrounded to form a mold space for blowing the bottle. The bottom die device of the blow-hot filling bottle is characterized in that the cylinder shaft penetrates through the cylinder end cover and is communicated with the inside of the supporting column for supporting and fixing the heating body, a wire can be introduced into the cylinder shaft through the inside of the cylinder shaft and is connected with the heating body, the inner space of the cylinder device is fully utilized, and the wire is prevented from being corroded or pulled apart outside the cylinder device in the working process. The positioning spigot arranged at the lower end of the cylinder end cover is matched with the positioning boss arranged at the upper end of the support, so that the cylinder device and the support can be quickly positioned, and the cylinder device can be conveniently and accurately installed on the support. Meanwhile, the clamping sleeve is also sleeved in the clamping device, and at the moment, the clamping shaft is only jacked up to push the moving part to clamp the bulge of the clamping sleeve, so that the cylinder device can be firmly fixed on the support. The clamping device is simple in structure, the clamping shaft pushes the moving part to clamp the buckle of the clamping sleeve, so that the cylinder shaft and the support can be quickly installed and fixed, and the clamping device is convenient and quick and high in efficiency.

In the bottom die device for blowing hot bottles, the bottom of the clamping shaft 73 is connected with a cylinder, and the movable piece 72 is pushed up and down by the cylinder. Also can connect the clamping shaft bottom through the motor, realize the up-and-down motion of clamping shaft, upwards can promote the moving part and block the buckle to keep the chucking fixed, when needs are dismantled, alright will press from both sides the downward motion of clamping shaft through cylinder or motor, loosen the moving part, alright easily dismantle cylinder device from the support.

In the bottom die device for blowing hot filling bottles, an arc-shaped bulge is arranged at the top of the clamping shaft 73. The protruding better with the moving part of arc top is released, prevents that the clamping shaft from dying with the moving part card, leads to the clamping shaft can't release the moving part and block the buckle of clamping sleeve.

In the bottom die device for blowing hot bottles, the moving member 72 is a steel ball. The surface of steel ball is circular-arc, can conveniently be released by the tight axle of clamp, when needing to dismantle simultaneously, has lost the support of pressing from both sides tight axle, and the steel ball also can no longer block the buckle through rolling the return, can be quick dismantle the cylinder device from the support.

In the bottom die device for blowing hot filling bottles, grooves 74 are vertically formed in two side walls of the clamping device 7, springs 75 are arranged in the grooves, the top ends of the springs abut against the support, and when the air cylinder device is installed on the support, the support pushes the air cylinder device downwards and the springs are compressed to abut against the support tightly. When the cylinder device needs to be detached from the support, after the clamping shaft is loosened to abut against the moving part of the buckle, upward force is applied to the support due to the restoring elastic force of the spring, the edge of the support, which is in contact with the clamping device, simultaneously pushes the clamping sleeve upwards, the moving part can be pushed back to the inside of the cylinder body, and the cylinder device can be further rapidly detached from the support.
