Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing.
[0013] The structure of the present invention is as figure 2 As shown, it includes the left and right fingers rotating around the center o3 of the finger circle. When the fingers are opened and closed, the left and right fingers rotate synchronously and in reverse. The front ends of the left and right fingers form a finger opening consisting of two different arcs. The radius of the arc at the front end is R1, and the radius of the arc at the back end is R2. The center o2 of the end arc, the center o1 of the front end arc, and the center o2 of the rear end arc are equal in distance from the center o3 of the finger.
[0014] The working mode of the present invention is as image 3 As shown, when clamping a plastic bottle with a small neck, only the front arc touches the diameter of the bottle; when clamping a plastic bottle with a large neck, the fingers open at a certain ...

The invention provides a clamping finger suitable for transferring plastic bottles with two types of bottlenecks. The clamping finger suitable for transferring the plastic bottles with the two types of bottlenecks comprises a left clamping finger and a right clamping finger which rotate around the center of a circle, wherein clamping finger openings are formed at the front ends of the left clamping finger and the right clamping finger; each clamping finger opening comprises two segments of non-concentric circular arcs; the extended line of the angular bisector of the front-end circular arc passes through the center of a circle of the back-end circular arc; and the distance from the center of the circle of the front-end circular arc to the center of the circle of the clamping fingers is equal to the distance from the center of the circle of the back-end circular arc to the center of the circle of the clamping fingers. The clamping finger suitable for transferring the plastic bottles with the two types of bottlenecks has the beneficial effects that the transferring of the plastic bottles with the two types of different bottlenecks can be realized with no need for additional mechanical structures; and the clamping finger is convenient to manufacture and low in cost.
Description
technical field [0001] The invention relates to the field of clamping tools for plastic bottles, and is applied to cleaning, sterilization, filling and sealing equipment of plastic bottles, in particular to a plastic bottle conveying gripper suitable for two kinds of bottlenecks. Background technique [0002] In the cleaning, sterilization, filling and sealing equipment of plastic bottles, the transfer of bottles is generally carried out by clamping the bottleneck. The fingers that hold the bottle are an essential part. [0003] The most commonly used PET bottles on the market have two bottleneck diameters of 28mm and 38mm. At present, most of the existing gripping fingers can only be applied to one of the bottlenecks, and a few types of gripping fingers can be applied to both bottlenecks, including through sliding Block-separated left and right pinches, such as figure 1 As shown, when it is used for a small bottle neck, the slider moves to the left; when it is used for a ...
