Technical Field

[0001] The utility model belongs to the technical field of capping equipment, and particularly relates to a quick-change structure of a capping head assembly. Background Art

[0002] In the production of beer and beverages, the bottles used to fill beer and beverages need to be sealed with bottle caps after filling for easy storage and transportation. Bottles are mostly sealed by pressing caps and screw caps, among which crown caps and ring-pull caps are the main ones. Due to the structural differences between crown caps and ring-pull caps, it is necessary to select corresponding crown cap pressing heads and ring-pull cap pressing heads when sealing bottles.

[0003] At present, most manufacturers adopt the form of co-production when the production process includes crown cap packaging and ring-pull cap packaging to achieve the purpose of cost saving. However, due to the differences in the structure and installation method of the crown cap head and the ring-pull cap head, it is difficult to replace the capping head: on the one hand, the space is limited when disassembling and assembling the capping head on the compact equipment, and the convenience of replacement is poor; on the other hand, when replacing the capping head, it is necessary to disassemble the removed capping head and then reassemble it again. The replacement process is cumbersome and time-consuming, affecting the overall production efficiency. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] See also Figure 1 and 2 As shown, the utility model is a quick-change structure of a capping head assembly, including a capping head fixing assembly 1 connected to a capping machine, the upper end of the capping head fixing assembly 1 is connected to the capping machine, the lower end of the capping head fixing assembly 1 has a guide sleeve 101, and an adapter 2 sleeved with the guide sleeve 101.

[0030] The inner wall of the guide sleeve 101 is provided with an annular groove 102 and two symmetrically arranged insertion grooves 103, and the upper end of the insertion groove 103 is connected to the annular groove 102, and the lower end passes through the lower end surface of the guide sleeve 101. At the same time, the side wall of the guide sleeve 101 is provided with a threaded hole, and is connected with a self-locking spring pin 3, and the end of the self-locking spring pin 3 extends into the interior of the guide sleeve 101.

[0031] like Figure 6 As shown, the lower end of the adapter 2 is used to connect the capping head, and the upper end of the adapter 2 is a columnar structure adapted to the inner wall of the guide sleeve 101, and is a sleeve-like structure with a through hole in the center.

[0032] The circumferential surface of the adapter 2 is fixedly connected with a clamping block 201 corresponding to the insertion slot 103. In addition, the adapter 2 is provided with a latch hole 202.

[0033] Among them, Figures 3 to 5 As shown, when the capping head is a crown cap capping head 4 , the crown cap capping head 4 is provided with a clamping block 201 and a latch hole 202 structure of the adapter 2 , such as directly providing the clamping block 201 and the latch hole 202 on the outer wall of the crown cap capping head 4 .

[0034] like Figures 6 to 9 As shown, when the gland head is a ring-pull gland head 5, the outer wall of the adapter 2 is provided with an external thread, and is threadedly connected and fixed with the ring-pull gland head 5. In addition, the adapter 2 is threadedly connected with a nut 203, and after the threaded connection sleeve of the ring-pull gland head 5 is threadedly connected with the adapter 2, the ring-pull gland head 5 is locked by the locking nut 203, including the connection and fixation between the ring-pull gland head 5 and the adapter 2.

[0035] When installing the capping head, pull the self-locking spring pin 3, and when the block 201 corresponds to the insertion groove 103, insert the adapter 2 into the guide sleeve 101 from bottom to top, and insert the block 201 into the annular groove 102 by rotation. At this time, the axial position of the adapter 2 is limited. When the adapter 2 is rotated to the position of the pin hole 202 corresponding to the self-locking spring pin 3, the self-locking spring pin 3 is inserted into the pin hole 202 to achieve the synchronous limitation of the circumferential direction and axial position of the adapter 2, thereby completing the installation of the capping head through the adapter 2.

[0036] The block 201 is in a strip structure, so that the contact area between the block 201 and the annular slot 102 is increased, which is beneficial to improving the stability and reliability of the connection. When disassembling, it is only necessary to pull the self-locking spring pin 3, and then rotate the adapter 2 so that the block 201 corresponds to the insertion slot 103, and then the adapter 2 can be pulled out to complete the disassembly of the capping head.

[0037] By providing the crown cap pressing head 4 and the pull ring cap pressing head 5 with a clamping block 201 structure which is also matched with the annular clamping groove 102 in the guide sleeve 101, the overall versatility is improved, and the crown cap pressing head 4 and the pull ring cap pressing head 5 can be quickly disassembled and replaced, thereby effectively improving the convenience of replacing the pressing heads, making the replacement process simpler, and being conducive to improving the overall production efficiency.
