[0035] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations may be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as a part of an embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the embodiments of the present invention should belong to the scope of protection of the embodiments of the present invention.

[0036] At present, in the process of chain production and packaging, the chains are mainly folded and packaged manually through cooperation between workers, which has extremely low production efficiency. In addition, each production line needs to be equipped with multiple people to fold the chains, which requires huge manpower costs.

[0037] Based on this, the present application embodiment proposes a chain automatic folding device, such as Figures 1 to 12 As shown, the automatic chain folding device includes: a workbench 1, a driving unit and a folding unit 2, wherein the driving unit and the folding unit 2 are both arranged on the workbench 1, and driven by the driving unit, the chain to be folded placed on the folding unit 2 is folded to meet the packaging requirements.

[0038] The folding unit 2 includes N guide grooves, and the adjacent guide grooves are in a T-shaped structure, and the length of the i+1 guide groove is half of the length of the ith guide groove, and the width of the i+1 guide groove is twice the width of the ith guide groove, thereby effectively ensuring the straightness of the chain after folding and avoiding bending and twisting of the chain during the folding process. Wherein, i∈N, i and N are both positive integers.

[0039] A folding start opening 11 is provided on the i-th guide groove, and the folding start opening 11 is directly opposite to the connection of the T-shaped structure of the i+1 guide groove and the i-th guide groove. Under the action of the driving unit, the folding rod 9 (cylindrical) adapted to the folding start opening 11 moves to the folding start opening 11, and folds the chain to be folded placed in the i-th guide groove along the i+1 guide groove. Here, the inlet and outlet of each guide groove and the folding start opening 11 are all smoothly transitioned to effectively avoid scratches on the folding rod 9 and the chain during the chain folding process.

[0040] The guide groove is arranged on the workbench 1 and can be fixed by welding or detachable connection. Specifically, a plurality of mounting screw holes are provided on the workbench 1, and mounting through holes corresponding to the mounting screw holes are provided on the guide groove, and the guide groove is fixed on the workbench 1 by fastening screws. Furthermore, the guide groove can be adjusted and replaced according to different specifications and models of the chain, effectively improving the adaptability of the guide groove to chains of different specifications and models.

[0041] A roller bearing 10 is also provided at the connection of the T-shaped structure of the i+1th guide groove and the ith guide groove, and there are two roller bearings 10, which are symmetrically arranged at the connection of the T-shaped structure. Specifically, facing the folding start opening 11 of the i-th guide groove, two roller bearings 10 are symmetrically arranged on both sides of the interface between the i+1th guide groove and the i+1th guide groove, so that during the chain folding process, when the chain slides from the i-th guide groove to the i+1th guide groove under the action of the cylindrical folding rod 9, the chain slides under the action of the roller bearings 10, effectively avoiding scratches on the chain.

[0042] In the present application, the driving unit adopts a synchronous belt slide, specifically including: an X-direction synchronous belt slide, a Y-direction synchronous belt slide 4 and an electromagnetic push rod 8. The X-direction synchronous belt slide is installed on the workbench 1, the Y-direction synchronous belt slide 4 is installed on the slider 13 of the X-direction synchronous belt slide, the electromagnetic push rod 8 is installed on the slider 13 of the Y-direction synchronous belt slide 4, and a folding rod 9 is installed at the end of the electromagnetic push rod 8. Thereby, the X-direction synchronous belt slide drives the Y-direction synchronous belt slide 4 to move along the X direction, the Y-direction synchronous belt slide 4 drives the electromagnetic push rod 8 to move along the Y direction, and the electromagnetic push rod 8 drives the folding rod 9 to move along the normal direction of the workbench 1. Furthermore, the folding rod 9 moves along the X direction, the Y direction and the vertical direction, enters from the folding starting openings 11 of different guide grooves, and folds the chain in the guide grooves in different directions.

[0043] In a specific example, the X-direction synchronous belt slide includes a left slide 5 and a right slide 7, which are arranged in parallel along the X direction on both sides of the folding unit 2, and the left slide 5 and the right slide 7 move synchronously. Specifically, the left slide 5 and the right slide 7 share a driving motor (servo motor, stepper motor, etc.), and a linkage shaft 6 is provided between the left slide 5 and the right slide 7, and power is transmitted through the linkage shaft 6, so that the left slide 5 and the right slide 7 move synchronously.

[0044] The two ends of the Y-direction synchronous belt slide 4 are respectively connected to the sliders 13 of the left slide 5 and the right slide 7 through the L-shaped bracket 12. Specifically, the bottom plate 14 of the L-shaped bracket 12 is detachably mounted on the slider 13 by bolts, and the vertical plate of the L-shaped bracket 12 is detachably connected to the Y-direction synchronous belt slide 4 by bolts, thereby driving the Y-direction synchronous belt slide 4 to move along the X direction through the X-direction synchronous belt slide.

[0045] In another specific example, the X-axis synchronous belt slide is installed on the workbench 1 through a slide bracket 3. Specifically, there are four slide brackets 3, which are respectively located at the four corners of the folding unit 2 and arranged in a rectangular shape; the left slide 5 and the right slide 7 are respectively symmetrically arranged on the two slide brackets 3 facing each other in the X direction. Among them, the slide bracket 3 includes: a bottom plate 14 and a support frame 15, the bottom plate 14 is detachably connected to the workbench 1, and the top surface of the bottom plate 14 is provided with an X-axis limit groove 17; the support frame 15 is located in the X-axis limit groove 17, and is threadedly connected to the bottom plate 14 by a clamping bolt, and a Y-axis limit installation groove 16 is provided on the support frame 15, and a limit installation plate 18 is symmetrically arranged on both sides of the Y-axis limit installation groove 16, and a waist-shaped hole is opened on the limit installation plate 18, and the left slide 5 (or the right slide 7) is connected by bolts passing through the waist-shaped holes to detachably connect the X-axis synchronous belt slide. Thus, the synchronous belt slide is fixed on the workbench 1 through the limit installation in the X direction and the Y direction, which effectively prevents the slide from shifting due to vibration during the working process and improves the accuracy of the chain folding.

[0046] When folding the chain, the electromagnetic push rod 8 is placed in the initial position. After the folding chain is integrated into the first guide groove, the folding rod 9 is controlled to move to the folding starting port 11 of the first guide groove, and the electromagnetic push rod 8 is controlled to push out and drive the folding rod 9 downward, and the X-direction synchronous belt slide moves, and drives the folding rod 9 along the second guide groove to fold the chain to be folded, and completes the first folding of the chain; then, the electromagnetic push rod 8 is controlled to retract, drive the folding rod 9 upward, and move to the folding starting port 11 of the second guide groove, and then the electromagnetic push rod 8 is controlled to push out and drive the folding rod 9 downward, and the Y-direction synchronous belt slide 4 moves, and drives the folding rod 9 along the third guide groove to fold the chain to be folded, and completes the second folding of the chain. Cycle in sequence until the chain folding is completed, control the electromagnetic push rod 8 to retract, drive the folding rod 9 upward, and at the same time, control the X-direction synchronous belt slide and the Y-direction synchronous belt slide 4 to move, so that the electromagnetic push rod 8 returns to the initial position. Here, it should be noted that the electromagnetic push rod 8 can also be replaced with a pneumatic push rod, a steering gear, etc.
