How to position the bolts and the blocks at the front end of the rear section chain belt and the rear end of the front section chain belt becomes the technical problem which is mainly solved by the bidirectional double-open zipper cutting equipment.
Disclosure of Invention
The invention aims to provide a bidirectional double-opening zipper notch positioning device which can effectively position a bidirectional double-opening zipper notch and has high working efficiency.
In order to achieve the technical purpose, the technical scheme of the invention is as follows:
the bidirectional double-opening zipper notch positioning device comprises a zipper passing platform, wherein the zipper passing platform is provided with a notch positioning block, the notch positioning block is connected to a positioning sliding rod, the positioning sliding rod is connected with a positioning sliding chute in a sliding manner, the positioning sliding rod slides along the advancing direction of a zipper belt, the positioning sliding rod is provided with a resetting device, and the resetting device resets the positioning sliding rod after the positioning sliding rod slides along the advancing direction of the zipper belt;
the notch positioning block comprises a rear fixing groove block and a front fixing groove block, a press belt gap is formed between the rear fixing groove block and the front fixing groove block, a rear left clamping groove, a rear right clamping groove and a rear chain-dividing guide block are arranged on the upper surface of the rear fixing groove block, the rear chain-dividing guide block is arranged between the rear left clamping groove and the rear right clamping groove, a front left clamping groove, a front right clamping groove and a front chain-dividing guide block are arranged on the upper surface of the front fixing groove block, the front chain-dividing guide block is arranged between the front left clamping groove and the front right clamping groove, and openings of the rear left clamping groove, the rear right clamping groove, the front left clamping groove and the front right clamping groove face the outside;
and a pressing device is arranged at the belt pressing gap and presses the chain belt downwards towards the inner side of the belt pressing gap 23.
When the zipper dividing device is used, a zipper to be divided is conveyed to pass through the zipper passing platform, and the zipper belts on the left side and the right side respectively pass through two sides of the zipper dividing guide block (the rear zipper dividing guide block and the front zipper dividing guide block) (namely the zipper dividing guide block extends into the space between the zipper belts on the left side and the right side); in the advancing process of the chain belt, the plug pin and the square at the front end of the rear chain belt are respectively clamped into the rear left clamping groove and the rear right clamping groove; when the inserted pin and the square block clamped into the rear left clamping groove and the rear right clamping groove continue to advance, the notch positioning block (positioning slide rod) is driven to slide along the advancing direction of the chain belt; after the positioning block to be cut slides along the advancing direction of the chain belt, stopping conveying the chain belt, and pressing the left and right side chain belts downwards towards the inner side of the pressing belt gap by the pressing belt device to enable the plug pin and the square block at the rear end of the front section chain belt to be respectively clamped into the front left clamping groove and the front right clamping groove; and (3) after the inserted pin and the square block at the rear end of the front-section chain belt are respectively clamped into the clamping grooves, positioning the inserted pin and the square block so as to position and cut the chain belt, and preparing the bidirectional double-open zipper.
The outer side walls of the rear left clamping groove, the rear right clamping groove, the front left clamping groove and the front right clamping groove are in a ladder shape. The stepped clamping groove on the outer side wall can prevent the chain belt from being bent, and the pin or the square block can be effectively clamped. Specifically, after the bolt or the square block is clamped into the clamping groove, the outer side wall of the opening side of the clamping groove is lower than the height of the chain belt, the outer side wall of the inner side of the clamping groove is larger than or equal to the height of the bolt or the square block, the bolt or the square block is limited in the radial direction by the outer side wall of the opening side of the clamping groove, and the outer side wall of the inner side of the clamping groove resists against the end part of the bolt or the square block; because the lateral wall on the opening side of the clamping groove is lower than the height of the chain belt, when the bolt or the square block is clamped into the clamping groove, the lateral wall on the opening side of the clamping groove does not influence the chain belt to move, so that the bolt or the square block only moves radially, and the phenomenon that the chain belt is bent due to the overhigh lateral wall to influence the positioning effect is avoided.
The positioning slide rod is provided with a slide rod sensor which is used for monitoring whether the notch positioning block slides along the advancing direction of the chain belt. Whether the positioning slide rod slides or not is monitored by using the slide rod sensor so as to monitor whether the notch positioning block slides along the advancing direction of the chain belt or not, and the chain belt conveying is conveniently stopped in time.
The sliding rod sensor is arranged on one side of the positioning cross rod, the positioning cross rod is fixedly connected with the positioning sliding rod, and the sliding rod sensor is used for monitoring whether the positioning cross rod slides along the notch positioning block or not. Whether the positioning cross rod moves along with the positioning slide rod or not is monitored by using the slide rod sensor so as to monitor whether the notch positioning block slides along the advancing direction of the chain belt or not, and the chain belt conveying is conveniently and timely stopped.
The slide bar sensor is a proximity switch.
