Description

Technical Field

[0001] The invention relates to the technical field of mechanical clamping structures, in particular to a clamping hand assembly for a rotary bottle blowing machine. Background Art

[0002] PET bottled water production line is an automated equipment specially used for producing PET (polyethylene terephthalate) bottled water. This production line can complete a series of processes from raw material preparation to finished product packaging. During the production process, a series of operations such as preform heating, bottle blowing, empty bottle inspection, cleaning and disinfection, filling, capping, labeling, coding, and packaging can be carried out. The traditional PET bottled water rotary blow molding machine is used to clamp the preform into the mold and clamp the bottle out of the mold. It relies on the preform or bottle to squeeze open the spring-loaded gripper opening to complete the gripping and release of the preform or bottle. The bottle mouth is easily deformed by impact during the release process, resulting in product loss. At the same time, PET debris is generated due to friction during the clamping and releasing process, causing product contamination. In addition, the gripper structure of the existing bottle blowing machine is simple. When the equipment position is deviated, it is easy to cause clamping failure, thereby affecting the working stability of the gripper. In addition, the traditional gripper relies on the elastic force of the spring to clamp the bottle mouth. During the bottle transfer process, the bottle body is subjected to force, which causes the gripper to expand outward, easily causing the bottle to fall off, thereby affecting the practicality of the gripper. Therefore, it is very necessary to design a gripper assembly for a rotary bottle blowing machine. Summary of the Invention

[0025] Working principle: When in use, an expansion mechanism 3 that can drive the flip block 22 is added on the basis of the traditional clamping structure. Before docking the bottle mouth, the top pressure cylinder 39 is used to drive the limit frame 38 to move forward. During the process, the arc frame 37 in the limit frame 38 presses the force support 36 to make the side bracket 35 drive the support column 34 to rotate, and then the support column 34 drives the bottom rotating plate 32 to rotate.

At the same time, the negative pressure pump 77 in the auxiliary locking mechanism 7 is used to lift the bottle mouth. The negative pressure is supplied to extract the gas in the locking cylinder 74 through the connecting pipe 75, thereby driving the locking rod 76 to retract and pull the clamping parts 23 on both sides closer to each other, playing an auxiliary clamping effect, preventing the bottle from falling off due to force, thereby improving the practicality of the clamping hand; the observation camera 41 in the closed cover 42 is used to collect the position of the bottle mouth, and in the process, the transmission motor 48 is used to drive the transmission gear 46 on the output end of the reducer 47 to rotate.
