[0002] A zipper is mainly composed of chain teeth, a slider, upper and lower stops or locking parts. The slider, as an important structure to realize the opening and closing function of the zipper, mainly includes two parts: a slider body and a pull tab. The pull tab is usually assembled and rotated on the slider body.

[0003] For slider products that require injection molding, injection molding must be performed at the designated position of the slider material to obtain a layer of outer plastic wrapping; for example, for slider products that require injection molding of the pull tab, injection molding must be performed outside the pull tab, and plastic must be wrapped outside the metal pull tab. However, before the slider material is injected, the pull tab and the pull body are in a fitted state, or the angle between the pull tab and the pull body is not enough, which will affect the injection molding effect. The current solution is to manually open the pull tab to about 90° with the pull body; the inventors have found that the current solution has the following shortcomings: For sliders that require injection molding of the pull tab, the pull tab needs to be manually opened on a daily basis before subsequent injection molding work can be performed, and the production efficiency is extremely low.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] In view of the problems existing in the manual pulling of the pull tab in the aforementioned prior art solutions, the present application provides a pull tab pulling device to realize the automatic pulling tab function.

[0028] Please refer to Figures 1 to 4 ,in, Figure 1 The overall structure diagram of the slider pull tab device and the automatic equipment provided in the embodiment of the present application is as follows: Figure 2 This is a schematic diagram of the principle structure of the pull head and pull tab device provided in the embodiment of the present application. Figure 3 This is a schematic diagram of the principle structure of the push-grab member provided in the embodiment of the present application. Figure 4 This is a schematic diagram of the principle structure of the slider limiter provided in an embodiment of the present application.

[0029] In the first specific implementation manner, the pull tab device provided by the embodiment of the present application mainly includes a feed track 1, a pull tab cylinder 2, a push-pull head cylinder 3 and a discharge track 4; the first end of the feed track 1 is an inlet for the pull tab material to enter, and the second end of the feed track 1 is an outlet for the pull tab material to leave; the action end of the pull tab cylinder 2 is equipped with a pull tab rod 5, and the pull tab rod 5 is used to move under the drive of the pull tab cylinder 2, so that the pull tab and the pull body of the pull tab material located at the outlet position are adjusted to a set angle; the action end of the push-pull head cylinder 3 is equipped with a push-grab member 6, and the push-grab member 6 is used to move under the drive of the push-pull head cylinder 3, so that the pull tab material located at the outlet position and adjusted to the set angle leaves the feed track 1 and enters the discharge track 4.

[0030] During the use of the slider pull tab device, first, the slider material is put into the feed track 1 from the inlet, and the slider material moves to the outlet in sequence from the inlet; then, for the slider material located at the outlet position, the pull tab cylinder 2 drives the pull tab rod 5 to move, and the pull tab rod 5 is extended to pull open the slider material, so that the slider and the slider body of the slider material are adjusted to the set angle, so as to facilitate the subsequent injection molding process of the slider; for the slider material located at the outlet position and completing the slider opening action, the push-pull cylinder 3 drives the push-grab member 6 to move, and the push-grab member 6 is extended to push the slider material away from the feed track 1, so that the slider material falls into the discharge track 4 for discharge; the above process is carried out with the slider material being progressively cycled one by one, that is, the slider material falls one by one, and the pull tab cylinder 2 and the push-pull cylinder 3 repeatedly act on each slider material.

[0031] In combination with the above structure and process description, it can be seen that the slider pull tab device has at least the following beneficial effects: compared with the manual pull tab action, the slider pull tab device realizes the function of automatically pulling the pull tab, thereby achieving efficient automation.

[0032] It should be noted that the present embodiment does not limit the setting direction of the feed track 1. That is to say, the horizontal setting, vertical setting and settings in other directions of the feed track 1, as long as they can achieve the effects described in the above technical solution, should also fall within the description scope of the present embodiment.

[0033] As an option, the feed track 1 is arranged vertically, the upper end of the feed track 1 is the inlet, and the lower end of the feed track 1 is the outlet. At this time, the pull head material enters the feed track 1 from top to bottom, and the outlet track 4 is located below the feed track 1.

[0034] In this embodiment, the pull-tab materials are arranged in sequence in the feed track 1, and the pull-tab cylinder 2 pushes the pull-tab rod 5 to pull the bottom pull-tab material in the feed track 1. After the pull-tab is pulled open, the pull-tab cylinder 2 drives the pull-tab rod 5 to retreat and reset. The push-tab cylinder 3 pushes the push-grab member 6 to push the pull-tab materials down one by one. The pull-tab work is completed in a cycle.

[0035] In some embodiments, the pull head and pull tab device further includes a pull head sensor 14 , and the pull head sensor 14 is arranged on the feeding track 1 at a position close to the entrance.

[0036] In this embodiment, the function of the slider sensor 14 is to detect the amount of slider materials in the feed track 1, and to send a signal when the amount of slider materials is too much, prompting the operator to stop feeding the slider materials into the feed track 1; based on this, if automatic feeding such as a vibration plate feeding method is adopted, the slider sensor 14 should control the vibration plate to stop working when it detects that the amount of slider materials reaches the sensing position.

[0037] In some embodiments, the pull head pull tab device also includes a push-grab connecting rod 7, a latch 8, a spring 9 and a push-grab limit plate 10. The action end of the push-grab cylinder 3 is connected to the first end of the push-grab connecting rod 7, and the second end of the push-grab connecting rod 7 is connected to the push-grab member 6 through the latch 8. The spring 9 is connected between the push-grab connecting rod 7 and the push-grab member 6, and the push-grab limit plate 10 is installed on the push-grab connecting rod 7; the push-grab member 6 is used to be pressed by the spring 9 when pushing away the pull head material and the push-grab limit plate 10 maintains the posture of the push-grab member 6, and the push-grab member 6 is used to move after pushing away the first pull head material and rotate around the latch 8 to the second pull head material.

[0038] In this embodiment, combined with Figure 2 and Figure 3 To explain, the push-grab piece 6 is connected to the push-grab connecting rod 7 through a horizontal pin 8. When the push-pull head cylinder 3 drives the push-grab connecting rod 7 and the push-grab piece 6 to push the pull head downward as a whole, the protruding part of the front end of the push-grab piece 6 contacts the shoulders of the pull head material and presses downward. At this time, the push-grab limit plate 10 clamps the rear end of the push-grab piece 6 to ensure that the push-grab piece 6 does not rotate around the pin 8 when it moves downward. The lower plane of the front end of the push-grab piece 6 contacts the pull head material and is subjected to force, pushing the pull head material downward. When a slider material is pushed downward, the slider push cylinder 3 drives the push-grab connecting rod 7 and the push-grab member 6 to reset upward as a whole, and the front end of the push-grab member 6 also rotates upward due to the overall upward reset and the action of the spring 9, and then the front end of the push-grab member 6 contacts the slider material to be pulled in the feed track 1, and the front end of the push-grab member 6 rotates downward around the latch 8, and after continuous contact and friction through the slider material above, it is inserted into the gap between the two slider materials and maintained, and the spring 9 supports the push-grab member 6 to ensure that the lower plane of the push-grab member 6 is restored to a horizontal level, in preparation for pushing the next slider material. The cycle is repeated in sequence, and the slider materials are pushed downward one by one.

[0039] Please continue to refer to Figure 4 In some embodiments, the slider pull tab device also includes a slider limit plate 11, a limit spring 12 and a spring seat 13, the limit spring 12 is connected between the slider limit plate 11 and the spring seat 13, the slider limit plate 11 is used to provide a clamping force to the slider material at the exit position, and the slider material at the exit position can overcome the clamping force of the slider limit plate 11 under the action of the push-grasp member 6.

[0040] In this embodiment, the combination of the slider limiter 11 and the slider cylinder 3 ensures that only one slider material is pushed down each time. The core technical solution of the slider puller device is not only the way of pulling the slider by the combination of the slider cylinder 2 and the slider cylinder 3, but also the combination of the slider cylinder 3 and the slider limiter 11 to achieve the sequential drop of the slider materials that have completed the pull, so as not to affect the pull action of the next slider material, thereby improving the efficiency and accuracy of the machine.

[0041] Furthermore, the slider limit plate 11, the limit spring 12 and the spring seat 13 are each in two groups, and the two groups of slider limit plates 11, the limit spring 12 and the spring seat 13 are arranged in mirror symmetry, and the two groups of slider limit plates 11 are clamped on both sides of the slider material at the exit position.

[0042] In this embodiment, the slider limiter 11, the limiter spring 12 and the spring seat 13 are divided into two groups, the left and right slider limiters 11 and the left and right slider limiters 11 cooperate to clamp the slider material at the same time. The slider limiter 11 is supported toward the middle by the limiter spring 12, and always keeps in contact with the slider material in the feed track 1, so as to limit the slider material above. When the push-grab member 6 pushes the slider material downward, the limiter spring 12 is compressed, and the gap between the left and right slider limiters 11 is opened, so that the slider material continues to contact and pass downward. The structures of the left and right slider limiters 11 are mirror images, and the middle area of ​​the slider limiters 11 is narrow at the bottom and wide at the top. When the widest part of the bottom slider material passes through, the slider material falls off; but under the pressure of the limiter spring 12, the left and right slider limiters 11 are always squeezed toward the middle to ensure that the slider material above is clamped and limited and does not fall off, thereby achieving the effect of only one slider material passing through at a time.

[0043] The present application also provides an automatic device for pulling a slider and a pull tab, comprising the above-mentioned slider pulling tab device, and the automatic device for pulling a slider and a pull tab further comprises a slider conveying device for conveying slider materials to the slider pulling tab device.

[0045] In some embodiments, the slider conveying device includes a vibration plate 15, and the outlet position of the vibration plate 15 is connected to the inlet position of the slider pulling tab device.

[0046] In this embodiment, the pull head material is loaded from the vibration plate 15, enters the inlet of the pull head pull tab device, slides down through the feed track 1, and enters the pull tab area. The pull tab cylinder 2 pushes the pull tab rod 5 to push open the pull tab of the bottom pull head material in the feed track 1, and the pull tab cylinder 2 drives the pull tab rod 5 to retreat and reset. The push-pull head cylinder 3 pushes the push-grab member 6 to push down the pull tab material, drop it into the discharge track 4, and then drop it into the storage box, and at the same time, the push-pull head cylinder 3 and the push-grab member 6 retreat and reset. The pull tab work is completed in a cycle.
