Description

Technical Field

[0001] The utility model relates to a capping device for a multi-station flushing and filling integrated machine. Background Art

[0002] Most of the existing capping devices of flushing and filling machines include an independent capping mechanism for screwing the bottle cap and a positioning mechanism for positioning the water bucket below the capping mechanism. The driving parts of the positioning mechanism and the capping mechanism are independent of each other, resulting in a complex structure of the capping device. Not only the cost is relatively high, but also many avoidance paths need to be set for the movement between the structures, resulting in complex capping actions and low efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a capping device for a multi-station flushing and filling integrated machine, which has a compact structure and high capping efficiency.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a capping device for a multi-station flushing and filling integrated machine, which includes a positioning jaw, a first bottom plate vertically arranged, a horizontal moving mechanism installed on the first bottom plate for driving the positioning jaw to move horizontally along one side of the first bottom plate, a vertical moving mechanism installed on the horizontal moving mechanism for driving the positioning jaw to move vertically, and a capping mechanism installed on the vertical moving mechanism. The positioning jaw is installed on the vertical moving mechanism, and the center of the space formed by the enclosure when the jaws are closed is directly below the capping mechanism.

[0005] Another implementation scheme, the horizontal moving mechanism includes a horizontal slide rail fixedly installed on the first bottom plate along the horizontal direction, a horizontal slider slidably connected to the horizontal slide rail, a horizontal base fixed to the horizontal slider, a horizontal bearing fixed to the first bottom plate, a horizontal lead screw rotatably connected to the horizontal bearing, a horizontal nut threadedly connected to the horizontal lead screw and fixedly connected to the horizontal base, a horizontal motor installed on the first bottom plate for driving the horizontal lead screw to rotate, and a horizontal drive pulley assembly connected between the horizontal motor and the horizontal lead screw.

[0006] Another implementation scheme, the vertical moving mechanism includes a vertical slide rail fixed to the horizontal base along the vertical direction, a vertical slider slidably connected to the vertical slide rail, a vertical base fixed to the vertical slider, a vertical bearing fixed to the horizontal base, a vertical lead screw rotatably connected to the vertical bearing, a vertical nut threadedly connected to the vertical lead screw and fixedly connected to the vertical base, a vertical motor installed on the first bottom plate and connected to the vertical lead screw, the capping mechanism is installed on the vertical base, and the positioning jaw is installed on the horizontal base.

[0007] In another embodiment, the cap screwing mechanism includes a cap screwing motor fixed on the vertical base, a torque limiter coaxial with and fixedly connected to the output shaft of the cap screwing motor, and a clamping claw coaxial with and fixedly connected to the torque limiter, wherein the clamping claw always has a tendency to move toward its own axis.

[0008] In another embodiment, the device includes a bottle cap guide rail fixedly mounted on the first base plate and used to guide the bottle cap to the bottom of the clamping claw. When the vertical motor drives the vertical base downward, the clamping claw is driven to move from top to bottom and clamp the bottle cap. Then the capping mechanism moves in the up and down directions and horizontal directions with the vertical base and the horizontal base, so that the bottle cap and the bottle cap guide rail are staggered. Then the positioning claw clamps the canned water bucket and positions it under the clamping claw. The vertical motor drives the vertical base downward to the mouth of the bucket. Then the capping motor rotates and the vertical motor drives the vertical base downward at the same speed as the bottle cap rotates downward to complete the tightening of the bottle cap.

[0009] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art: the positioning mechanism and the cap screwing mechanism of the utility model share a set of horizontal moving mechanisms, which makes the connection structure more compact, reduces the yielding action, and improves the efficiency of taking the bottle cap, positioning the level and tightening the bottle cap.
