[0002] The hand-held paper bag is mainly used for the packaging of clothes and gift boxes, two corresponding rope threading holes are formed in the upper end of the left and right bag surfaces of the hand-held paper bag, and the two ends of the rope are provided with collets, so that the rope threading is facilitated, and the collet is clamped in the bag body after passing through the rope threading hole, thereby forming a hand-held rope. A collet puller of a threading machine is disclosed in Chinese Patent No. CN216733227U, which solves the problem of collet pulling of the hand-held paper bag. However, it is found in use that the prior art still has some defects: the spacing between the rope threading holes on the bag surface of the hand-held paper bag needs to be different according to different paper bags, and the spacing is adjusted by setting a strip-shaped adjusting groove on a connecting plate in the above-mentioned patent, and the clamping pieces are installed on the adjusting groove through bolts. When adjusting the spacing, the bolts are loosened first, and then the spacing between the clamping pieces is adjusted manually. After the adjustment is completed, the bolts are tightened again. This adjusting method not only has general adjusting accuracy, but also wastes labor, is not convenient, and affects efficiency. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides a collet puller, which has an optimized collet puller component structure, is convenient and fast to adjust the spacing, and is flexible and adaptable to various specifications of bag bodies.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This embodiment discloses a card ejection mechanism, such as... Figs. 1-3As shown, the device includes a frame 1, on which a lifting frame 2 that moves up and down is mounted. The lifting frame 2 is equipped with a pair of clamping head extraction components 3 and an adjusting component 4. In order to realize the integrated structure of the left and right clamping parts of the clamping head extraction component 3, the clamping head extraction component 3 includes a fixedly mounted open clamping cylinder 302 and a left clamping part 303 and a right clamping part 304 mounted on the clamping plates on both sides of the open clamping cylinder 302. The left clamping part 303 and the right clamping part 304 are pulled out inward by the open clamping cylinder 302. The adjusting component 4 drives the pair of clamping head extraction components 3 to move closer to each other or further away from each other. Specifically, two clips are inserted into each side of the bag (one clip at each end of the rope). The clip removal component 3 of this invention is integrated, with one clip removal component 3 corresponding to the two clips on each side of the bag and the other clip removal component 3 corresponding to the other two clips on each side of the bag. The spacing between the pair of clip removal components 3 can be flexibly adjusted by the adjusting component 4. The clip removal component of this invention can quickly adjust the spacing for the rope hole spacing on bags of different sizes.

[0019] In a preferred embodiment, the adjusting component 4 includes a parallel slide rail 401 and a lead screw 402. The chuck extraction component 3 is provided with a slide block 301, which has a threaded hole 3011 that engages with the lead screw 402 and a slider 3012 that slidably engages with the slide rail 401. Relying on the slide block 301, the chuck extraction component 3 moves under the drive of the lead screw 402. A ball screw is preferred to achieve high-precision adjustment.

[0020] Furthermore, the lead screw 402 includes a first threaded portion 4021 and a second threaded portion 4022 with opposite thread directions. Slides 301 on a pair of pull-out clip components 3 are respectively disposed on the first threaded portion 4021 and the second threaded portion 4022. With this structure, when the lead screw 402 rotates, the pair of pull-out clip components 3 can be adjusted simultaneously, controlling their simultaneous approach or distance from each other, while maintaining a constant center distance. This ensures that during subsequent processing, the center of the paper bag and the center of the pair of pull-out clip components 3 remain aligned, making the positions of the pull-out clip components 3 and the drawstring holes on the bag more accurate and reliable.

[0021] Furthermore, the adjusting component 4 includes an adjusting motor 403 for driving the lead screw 402 to rotate. The adjusting motor 403 is preferably a servo motor. The rotation amount of the adjusting motor 403 is precisely adjusted by a servo controller, and then coordinated with the pitch stroke of the lead screw 402 and the slider to achieve automatic control of the spacing adjustment. Specifically, before each processing, only the spacing of the drawstring holes on the side of the bag needs to be measured, and then the spacing is input into the computer control system. The computer control system can calculate the required rotation angle of the adjusting motor and send the data to the servo controller to automatically adjust the spacing. Compared with traditional existing technologies, this invention can achieve fully automated adjustment, saving labor and time, and improving efficiency.

[0022] Furthermore, the left clamping member 303 and the right clamping member 304 are equipped with finger-gripping cylinders 5 for clamping the chuck head. The finger-gripping cylinders 5 are connected to an external air source to realize the clamping action of the chuck head, and the structure is simple and reasonable.

[0023] Furthermore, the frame 1 is equipped with a second slider 6 and a lifting motor 7. The lifting frame 2 includes a lifting plate 201, on which a track 8 and a rack 9 are provided. The track 8 is slidably engaged with the second slider 6, and the lifting motor 7 is equipped with a gear 701 that meshes with the rack 9. With the above structure, the rotation of the gear 701 of the lifting motor 7 can drive the lifting plate 201 to move up and down through the rack 9, thereby driving the lifting frame 2 to move up and down, and simultaneously driving the card pull-out component 3 to move up and down, so that the card pull-out component 3 can move into and out of the bag.

[0024] The working principle of this utility model is as follows: When the card pull-out operation is performed, the bag body reaches the corresponding work position, the rope threading mechanism threads the rope, and then the lifting frame 2 drives the card pull-out component 3 to move into the bag opening. The finger-clamping cylinders 5 on the left clamping component 303 and the right clamping component 304 clamp the card head inserted into the bag. Then, the opening clamping cylinder 302 controls the two side clamping plates to close (initially set to the open state), pulling the card head into the bag. Then, the lifting frame 2 rises and resets, pulling the card head upwards a certain distance during the process. Finally, the finger-clamping cylinder 5 releases the card head, thus ensuring that the card head will not come out of the rope threading hole. When changing to different specifications of bag body, the spacing of the rope threading holes on the side of the bag body is measured, and then the motor is adjusted by the computer control system (or manually). The pair of card pull-out components 3 move away from or closer to each other so that the spacing matches the rope threading holes of the bag body, making the adjustment convenient and quick.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
