Description

Technical Field

[0001] The invention relates to the technical field of labeling equipment, in particular to an adjustable bottle feeding spiral device. Background Art

[0002] The bottle feeding spiral is a device that transports bottles on the chain path into the bottle feeding star wheel. The pitch of the last section of the bottle feeding spiral is equal to the center distance between the two openings in the bottle feeding star wheel. Before production, the position of the bottle feeding spiral needs to be adjusted so that when the bottle is in the middle of the groove of the bottle feeding star wheel, the last section of the bottle feeding spiral is close to the bottle but does not move. Otherwise, the bottle will be stuck or exploded.

[0003] In actual production, a labeling machine can label bottles of various shapes and sizes. After adjusting the positions of the bottle feeding star wheel and the bottle feeding screw according to the first bottle size and labeling, it is necessary to adjust the position of the bottle feeding screw again when labeling bottles of the second bottle size. The existing patent CN205972123U discloses a bottle feeding screw adjustment mechanism, which includes a water pump bearing 1, a bottle feeding screw 2, a locking seat component 3, an adjustment seat 4, a clamping ring component 5, a transmission shaft 6, and a fixed arm. Component 7, movable arm component 8 and synchronous wheel component 9; the clamping ring component 5 is used to clamp the adjustment seat 4 and the transmission shaft 6, which includes a clamping ring 51 and four clamping screws 52. Each time adjustment is made, the four clamping screws 52 need to be opened to loosen the clamping ring component 5, and then the relative distance between the adjustment seat 4 and the transmission shaft is adjusted to complete the position adjustment; however, the structure of the bottle feeding spiral adjustment mechanism is relatively complicated, and each time adjustment is made, the four clamping screws 52 need to be opened and tightened after adjustment, which is time-consuming to operate. Summary of the Invention

[0004] In view of the above problems, an embodiment of the present invention provides an adjustable bottle feeding spiral device.
