Description

Technical Field

[0001] This utility model relates to a guiding device, and more specifically to a concealed zipper flip-up guide device. Background Technology

[0002] Currently, the production process of existing zipper tapes often requires the installation of guiding devices within the equipment to guide the movement of the zipper tape. These guiding devices primarily consist of an upper and lower mold, forming a guiding channel. When the zipper tape passes through this channel, it is guided by the channel's constraints. However, to ensure the guiding effect, the cross-section of the guiding channel must be matched to the cross-sectional height of the zipper tape. Existing zipper tapes are equipped with anti-detachment mechanisms to prevent the zipper pull from detaching. These anti-detachment mechanisms typically exceed the width and height of the zipper tape's cross-section. When encountering these anti-detachment mechanisms, the machine must stop, and the upper and lower molds must separate to allow the anti-detachment mechanism to pass through. This leads to a reduction in production efficiency. Utility Model Content

Attached Figure Description

[0012] Figure 1 This is an overall structural diagram of the concealed zipper flip-up guide device of this utility model;

[0013] Figure 2 for Figure 1 Overall structural diagram of the upper and middle mold section. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1As shown, the concealed zipper pull guide device of this embodiment includes an upper mold 1 and a lower mold 2. The upper mold 1 is vertically and vertically positioned above the lower mold 2, so that it can descend to merge with the lower mold 2 to form a guide channel, or rise to separate from the lower mold 2 to create a guide channel. The upper mold 1 includes an upper mold fixing block 11, a left movable cover 12, and a right movable cover 13. The left movable cover 12 and the right movable cover 13 are respectively movably mounted on the left and right sides of the upper mold fixing block 11, moving relative to each other or in opposite directions. The opposite side of the left movable cover 12 and the right movable cover 13 forms the upper mold portion of the guide channel with the lower side of the upper mold fixing block 11. Compared with the problem of reduced production efficiency caused by the need to stop and separate the upper mold 1 and lower mold 2 due to the need for anti-loosening of the zipper pull in traditional guide devices in the prior art, this structure can deal with the anti-loosening of the zipper pull by moving the left movable cover 12 and the right movable cover 13 in opposite directions, without stopping the machine, thus improving production efficiency.

[0016] Furthermore, the upper mold 1 also includes an upper mold mounting block 14, on which the upper mold fixing block 11 is fixedly mounted. The left movable cover 12 includes a left cover plate 121 and a left drive rod 122, and the right movable cover 13 includes a right cover plate 131 and a right drive rod 132. The left drive rod 122 and the right drive rod 132 are rotatably mounted on the upper mold mounting block 14. The left cover plate 121 and the right cover plate 131 are respectively fixedly mounted on the lower ends of the left drive rod 122 and the right drive rod 132. The opposite sides of the left cover plate 121 and the right cover plate 131 form a guide channel for the upper mold portion with the lower side of the upper mold fixing block 11. This structure makes the connection of each part of the upper mold 1 more reasonable, occupies less external space, and allows for more flexible control of the opening and closing of the guide channel, avoiding downtime due to anti-code slippage and improving production efficiency.

[0017] Furthermore, refer to Figure 2 As shown, a drive cylinder 141 is provided above the upper mold mounting block 14. The drive cylinder 141 is linked to the upper ends of the left drive rod 122 and the right drive rod 132 to drive the left drive rod 122 and the right drive rod 132 to rotate, so that the left cover plate 121 and the right cover plate 131 move relative to each other or in opposite directions. By driving the left movable cover 12 and the right movable cover 13 to move through the drive cylinder 141, the guide channel can be adjusted more accurately and quickly, preventing production stoppages caused by anti-code slippage and improving production efficiency.

[0018] Furthermore, the drive cylinder 141 is a pneumatic cylinder. The cylinder body of the drive cylinder 141 is fixedly installed above the upper mold mounting block 14. The push rod extends downward or retracts upward. The left drive rod 122 and the right drive rod 132 have drive grooves 15 on their opposite sides near the upper end. The lower end of the push rod of the drive cylinder 141 is fixed with a drive block 16, which is inserted into the drive groove 15 to wedge with the drive groove 15, causing the upper ends of the left drive rod 122 and the right drive rod 132 to swing relative to or away from each other. In this embodiment, the left drive rod 122 and the right drive rod 132 are elastically hinged to achieve reset. The use of pneumatic cylinder drive and wedge engagement makes the drive more efficient. At the same time, when anti-disengagement is not required, it has a stronger holding force and a faster response. When encountering anti-disengagement, it can adjust the guide channel in time, improving production efficiency.

[0019] Furthermore, a lifting column 17 is fixed to the upper side of the upper mold mounting block 14. The cylinder body of the drive cylinder 141 is fixedly installed on the upper end of the lifting column 17. A lifting block 142 is sleeved on the lifting column 17, and the drive block 16 is fixedly installed on the lifting block 142. The push rod of the drive cylinder 141 is linked with the lifting block 142 to drive the lifting block 142 to move up and down. This structure optimizes the connection method between the drive cylinder 141 and related components, making the overall operation more stable, better coping with anti-code slippage, and ensuring production efficiency.

[0020] Furthermore, a linkage groove 143 is provided on the side of the lifting block 142, and a linkage column is coaxially sleeved on the push rod of the drive cylinder 141. The linkage column has an annular groove, making its cross-section I-shaped. The linkage column is embedded in the linkage groove 143, and the groove wall of the linkage groove 143 is embedded in the annular groove. This connection structure makes the linkage between the drive cylinder 141 and the lifting block 142 more reliable, ensuring that the guide channel can be adjusted in a timely and accurate manner, and avoiding the impact on production efficiency due to anti-disconnection.

[0021] In summary, this concealed zipper flip-up guide device, through the design of the upper mold 1 being able to be raised and lowered and the left and right movable covers being able to move relative to each other or in opposite directions, combined with the synergistic effect of components such as the drive cylinder 141, effectively solves the problem in the prior art where the zipper tape anti-loosening mechanism requires stopping the machine to separate the upper and lower molds, thus reducing production efficiency, and significantly improves production efficiency.
