BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 A schematic diagram of a quick-change bottle pressing structure provided by the utility model;
[0016] Figure 2 It is a schematic diagram of the quick-change structure of the bottle pressing head. DETAILED DESCRIPTION
[0017] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0018] Example
[0019] Figure 1 , 2 As shown, a quick-change bottle pressing structure provided by the utility model includes a bottle pressing shaft 8, a bottle pressing head 5 and other components.
[0020] The bottle pressing shaft 8 is the rotating main shaft of the overall structure, and its upper key is connected to the synchronous pulley 1. The upper power can be transmitted through the engagement of the synchronous belt with the synchronous pulley 1 to provide power for the rotation of the structure; a fixing nut is sleeved below it, which cooperates with the bottle pressing flange seat 3 to fix the overall structure in a matching fixed position; two bearings 2 are sleeved below it, which cooperate with the bottle pressing flange seat 3, and a spacer sleeve 9 is provided between the two bearings 2 to protect the inner ring of the bearing 2 and prevent it from falling off. This design can be used as a guide for the bottle pressing shaft 8 and also enables it to rotate smoothly; two keyways and countersunk threaded holes are provided below it, and the connecting key 4 is fixed to the bottle pressing shaft 8 by a key fixing bolt 10 to limit the position of the bottle pressing head 5, and the slot on the other side provides a through-installation position for the quick-change pin 14.
[0021] The bottom of the bottle pressing head 5 matches with the bottle mouth of the container. Containers of different specifications require bottle pressing heads 5 of different specifications for pressing the caps. The structures of bottle pressing heads 5 of different specifications are the same, and the difference is that the sizes of the grooves below are different; a key slot, a quick-change pin installation position, a limiter installation position and a quick-change pin pressing avoidance position are provided on the bottle pressing head 5; the key slot cooperates with the connecting key 4 for limiting; the quick-change pin 14 is installed after the quick-change pin spring 13 is installed in the quick-change pin installation position, and the quick-change pin limiting member 12 is installed through the limiter installation position, and the quick-change pin 14 is pressed and limited, and the quick-change pin 14 extends from the quick-change pin pressing avoidance position to the outside of the bottle pressing head 5, and a square groove and a circular arc groove are respectively provided on both sides of the quick-change pin 14. The square groove is used for limiting the position of the quick-change pin limiter 12, and the radius of the arc groove is slightly larger than the radius of the corresponding position of the bottle pressing shaft 8; when installing the bottle pressing head 5, press the quick-change pin 14, the quick-change pin spring 13 is compressed, and the front end of the quick-change pin limiting groove contacts the quick-change pin limiting groove 12. At this time, the arc groove moves backward to a position concentric with the bottle pressing shaft 8, and the bottle pressing shaft 8 can be inserted into the quick-change pin 14. When the bottle pressing shaft 8 is inserted into place, the quick-change pin 14 rebounds under the action of the quick-change pin spring 13, and the rear end of the quick-change pin limiting groove contacts the quick-change pin limiting groove 12, limiting the quick-change pin 14, and the arc groove moves forward to lock the bottle pressing shaft 8; when disassembling the bottle pressing head 5, press the quick-change pin 14, and after the bottle pressing head 5 is pulled out from the bottle pressing shaft 8, the quick-change pin 14 is reset.
[0022] The lower side end of the bottle pressing head 5 is provided with a pin hole, and the pre-compression pin spring 6 is first installed in the lower end of the bottle pressing head 5, and then the bottle pressing head pre-compression pin 7 is installed, and then the side limit pin 11 is installed; when the bottle pressing structure presses the container downward, the bottle pressing head pre-compression pin 7 is compressed upward, and as the descending distance increases, the bottle pressing head 5 gradually presses the aluminum cover tightly. This process is flexible and controllable, effectively protecting the container and the aluminum cover below, and greatly improving the product yield; when there is a need to rotate the bottle body, the upper structure transmits the rotational power to the bottle pressing head 5, and when the bottle pressing head 5 presses the container tightly, it can stably and firmly drive the container to rotate.
