Embodiment Construction
[0027] The content of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as Figure 1-5 As shown, this embodiment provides a blow molding machine sealing and stretching linkage mechanism, the linkage mechanism is arranged between the sealing mechanism and the stretching mechanism, and cooperates with the sealing mechanism and the stretching mechanism to realize the sealing mechanism and the stretching mechanism. Linkage work. The linkage mechanism includes a linkage block 1 and a deflection assembly, the linkage block 1 is fixedly connected with the stretch rod 2, and the linkage block 1 drives the stretch rod 1 to move up and down under the driving action of the driving device 3; the deflection assembly, the deflection assembly and the head assembly 5 Fixed connection, in the initial state, the deflection assembly leans inward against both sides of the linkage block 1, when the linkage block 1 moves downward, th...

The invention relates to a sealing and stretching mechanism of a bottle blowing machine, in particular to a sealing and stretching linkage mechanism for the bottle blowing machine. The sealing and stretching linkage mechanism comprises a linkage block and an eccentric rotating assembly and further comprises a support, wherein the linkage block is fixedly connected with a stretching rod, the linkage block drives the stretching rod to move up and down under the driving effect of a drive device, the eccentric rotating assembly is fixedly connected with a head sealing assembly, in the initial state, the eccentric rotating assembly inclines inwards to abut against the two sides of the linkage block, when the linkage block moves downwards, the linkage block pushes the eccentric rotating assemblyoutwards, and the eccentric rotating assembly rotates outwards eccentrically and drives the head sealing assembly to move downwards to carry out sealing. The linkage block and the eccentric rotatingassembly are both arranged in the support. A sliding block is adopted as the linkage block. A sliding rail extending up and down is arranged on the support. The sliding block slides along the slidingrail up and down. Clamping grooves are formed in the left end and the right end of the linkage block correspondingly. The sealing and stretching mechanism solves the problem that stretching and sealing mechanisms of the bottle blowing machine in the prior art are controlled respectively, and precision is low.
Description
technical field [0001] The invention relates to a sealing and stretching mechanism of a bottle blowing machine, in particular to a sealing and stretching linkage mechanism of a bottle blowing machine. Background technique [0002] When the bottle blowing machine is blowing the bottle, firstly the preform is heated to a temperature that is easy to blow, and then sent to the mold by the robot, and then the bottle mouth is sealed by the sealing cylinder, and the preform is preformed into a bottle by blowing at a low pressure. The general shape of the bottle is stretched while blowing once to ensure that the bottle is not eccentric and stretched longitudinally. After the first blowing is completed, the bottle after the first blowing is blown into the mold by high-pressure secondary blowing. Laminating to form the final bottle, then recovering the high-pressure gas in the bottle cavity, and finally exhausting the excess gas to the atmosphere through the silencer. The traditional...
