[0033] Flexible strip products need to be packaged before leaving the factory. They need to be folded and cut, and then put into packaging before leaving the factory. Currently, flexible strip products are mainly folded manually.

[0034] In the related art, the folding of flexible strip products has the problems of being time-consuming, requiring a lot of manpower, being inefficient and costly.

[0035] Please refer to Figure 1-Figure 3 This embodiment provides a folding device 100, which can effectively improve the above-mentioned technical problems, can automatically perform multiple foldings, fold faster, simplify the folding process, improve folding efficiency, and reduce production costs.

[0036] The folding device 100 provided in this embodiment is mainly used for folding flexible strips. Of course, the folding device 100 can also be used for folding other objects to be folded, which is not specifically limited here.

[0037] Please refer to Figure 1 The present embodiment provides a folding device 100 including a unwinding member 10, a material pulling member 20, a first folding member 30 and a second folding member 40. The unwinding member 10 is used to wind up a flexible member 101, the material pulling member 20 is used to drive the flexible member 101 to move, the first folding member 30 is rotatably arranged relative to the unwinding member 10, the second folding member 40 is rotatably arranged relative to the unwinding member 10, and the second folding member 40 and the first folding member 30 are arranged at intervals. The flexible member 101 is used to be folded around the first folding member 30 under the traction of the material pulling member 20, and then the first folding member 30 and the second folding member 40 rotate in sequence to fold the flexible member 101 multiple times.

[0038] Specifically, the material pulling member 20 is located on one side of the unwinding member 10, and the first folding member 30 and the second folding member 40 are located on the other side of the unwinding member 10. The unwinding member 10 includes an unwinding head 11, and the end of the flexible member 101 is arranged on the unwinding head 11, so that the material pulling member 20 can pull the end of the flexible member 101 to move.

[0039] In this embodiment, the material pulling member 20 includes a material pulling jaw 21 and a moving track 22. The material pulling jaw 21 is movably arranged on the moving track 22. The material pulling jaw 21 is used to connect with the flexible member 101, and the material pulling jaw 21 is used to drive the flexible member 101 to move along the moving track 22. Specifically, the material pulling jaw 21 can automatically open and close to press or release the flexible member 101.

[0040] The material pulling member 20 also includes a moving motor 23 and a transmission belt, which is rotatably connected to the moving track 22. The moving motor 23 is connected to the transmission belt, and the material pulling clamp 21 is connected to the conveyor belt. The transmission belt is used to rotate under the drive of the moving motor 23, thereby driving the material pulling clamp 21 to move relative to the moving track 22.

[0041] It should also be explained that the material pulling clamp 21 includes a clamp body 211 and a rotating motor 212, the rotating motor 212 is connected to the movable track 22, the clamp body 211 and the rotating motor 212 are connected, and the clamp body 211 is used to drive the flexible member 101 to rotate under the drive of the rotating motor 212, so that the flexible member 101 is wrapped around the first folding member 30.

[0042] Specifically, when the clamp body 211 drives the flexible member 101 to move to the first folding member 30 , the rotary motor 212 drives the clamp body 211 to rotate, so that the flexible member 101 is wound around the first folding member 30 , completing the first folding.

[0043] In this embodiment, the first folding member 30 includes a first motor 31, a rotating arm 32 and a first central axis 33. One end of the rotating arm 32 is connected to the first motor 31, and the other end of the rotating arm 32 is connected to the first central axis 33. The flexible member 101 is used to be wound around the first central axis 33, and the rotating arm 32 is used to drive the first central axis 33 to rotate under the drive of the first motor 31.

[0044] Specifically, the first center shaft 33 rotates clockwise.

[0045] In this embodiment, the second folding member 40 includes a second motor 41, a second center axis 42 and a third center axis 43. The second center axis 42 is connected to the second motor 41, and the third center axis 43 is connected to the second center axis 42. The first center axis 33, the second center axis 42 and the third center axis 43 are arranged in sequence and located on the same straight line. The second center axis 42 is used to drive the third center axis 43 to rotate under the drive of the second motor 41.

[0046] Among them, the connecting line between the midpoint of the second central axis 42 and the midpoint of the third central axis 43 forms a connecting arm. The second central axis 42 rotates under the drive of the second motor 41, and at the same time drives the third central axis 43 to rotate around the center of the second central axis 42.

[0047] In this embodiment, the length of the connecting arm formed by the line between the midpoint of the second central axis 42 and the midpoint of the third central axis 43 is smaller than the length of the rotating arm 32 of the first folding member 30 .

[0048] The third center shaft 43 rotates counterclockwise.

[0049] Specifically, the rotation direction of the third central axis 43 and the rotation direction of the first central axis 33 are both determined according to the actual folding conditions of the material. The rotation direction of the third central axis 43 can be the same as or opposite to the rotation direction of the first central axis 33, and is not specifically limited here.

[0050] It should also be explained that since the first central axis 33, the second central axis 42 and the third central axis 43 have a certain circumference, the flexible member 101 will consume a certain length when it is wrapped thereon. In order to compensate for the consumed circumference, the folding device 100 also includes a buffer 50. The buffer 50 is arranged between the second central axis 42 and the third central axis 43. The buffer 50 is used to perform buffering compensation on the flexible member 101 when the third central axis 43 rotates, so as to prevent the flexible member 101 from being stuck or being too tight and deformed during the folding process.

[0051] Specifically, the buffer 50 is a spring, one end of the buffer 50 abuts against the second center axis 42, and the other end of the buffer 50 abuts against the third center axis 43. The buffer 50 is used to make corresponding adjustments according to the change in the circumference of the flexible member 101 when the third center axis 43 drives the flexible member 101 to rotate.

[0052] Furthermore, the folding device 100 further includes a mounting plate 60 , which is connected to the output ends of the first motor 31 and the second motor 41 , and the rotating arm 32 and the second central shaft 42 are both mounted on the mounting plate 60 .

[0053] In this embodiment, the folding device 100 further includes a cutting piece 70, which is disposed between the folding piece and the unwinding piece 10, and is used to cut the flexible piece 101. Specifically, the cutting piece 70 includes a pair of scissors 71, and the scissors 71 are used to cut the flexible piece 101.

[0054] Among them, after the material pulling clamp 21 drives the flexible member 101 to be wound onto the first central axis 33, the material pulling clamp 21 drives the flexible member 101 to move in the opposite direction, that is, to move towards the direction close to the unwinding member 10. When the material pulling clamp 21 moves to the initial position, the cutting member 70 cuts the flexible member 101.

[0055] It should also be noted that the material cutting member 70 further includes a clamping head 72, which can clamp the flexible member 101. After the material pulling clamping claw 21 drives the flexible member 101 to move toward the direction close to the unwinding member 10, the clamping head 72 clamps the end of the flexible member 101, and then the scissors 71 cut the flexible member 101, and the material pulling clamping claw 21 retreats to wait for the next pulling operation.

[0056] Specifically, the clamping head 72 is disposed between the third central shaft 43 and the scissors 71 .

[0057] In addition, in order to prevent the clamping head 72 from over-tightening the flexible member 101 and causing deformation thereof after the flexible member 101 is folded, a buffer spring is provided on the clamping head 72 so that the clamping head 72 can compensate for the circumference of the flexible member 101 .

[0058] When the folded flexible member 101 is cut, in order to ensure smooth cutting of the flexible member 101, the first folding member 30 further includes a telescopic cylinder connected to the first central axis 33, and the telescopic cylinder can drive the first central axis 33 to extend and retract.

[0059] In this embodiment, the direction in which the telescopic cylinder drives the first central axis 33 to extend and retract is parallel to the setting direction of the rotating arm 32 .

[0060] According to the working principle of a folding device 100 provided in this embodiment:

[0061] Place the flexible member 101 on the unwinding member 10, and press the end of the flexible member 101 against the unwinding head 11, leaving a length of 10 mm so that it can be clamped by the clamp body 211. The mobile motor 23 drives the transmission belt to move, and the clamp body 211 is driven by the transmission belt to pull the flexible member 101 in the direction away from the unwinding member 10. When it moves to the first folding member 30, the rotating motor 212 drives the clamp body 211 to rotate, so that the flexible member 101 is wrapped around the first folding member 30, completing the first folding; the clamp body 211 continues to drive the flexible member 101 to move, and the moving direction is now close to the unwinding member 10. When the flexible member 101 moves to the position of the clamping head 72, it is clamped. The head 72 clamps the end of the flexible member 101, and then the scissors 71 cut the flexible member 101, and the clamp body 211 retreats to wait for the next traction operation; then the first motor 31 drives the rotating arm 32 to rotate clockwise, and the first center axis 33 rotates clockwise under the drive of the rotating arm 32, and the flexible member 101 is folded in half by the third center axis 43, completing the second folding; then the second motor 41 drives the second center axis 42 to rotate counterclockwise, thereby driving the third center axis 43 to rotate counterclockwise, thereby completing the third folding.

[0062] The folding device 100 provided in this embodiment has at least the following advantages:

[0063] The folding device 100 folds the flexible member 101 multiple times by rotating and winding, thereby improving the automation rate, reducing manpower, greatly improving the folding efficiency, and saving costs.

[0064] In summary, an embodiment of the present invention provides a folding device 100, which includes a unwinding member 10, a material pulling member 20, a first folding member 30 and a second folding member 40. The unwinding member 10 is used to wind up the flexible member 101, the material pulling member 20 is used to drive the flexible member 101 to move, the first folding member 30 is rotatably arranged relative to the unwinding member 10, the second folding member 40 is rotatably arranged relative to the unwinding member 10, and the second folding member 40 and the first folding member 30 are arranged at intervals. The flexible member 101 is used to fold around the first folding member 30 under the traction of the material pulling member 20, and then the first folding member 30 and the second folding member 40 rotate in sequence to fold the flexible member 101 multiple times. When the folding device 100 is in use, the flexible member 101 is unwound by the unwinding member 10, and the material pulling member 20 pulls the flexible member 101 to move to the first folding member 30 for the first folding, and then the first folding member 30 and the second folding member 40 rotate in sequence, thereby driving the flexible member 101 to fold again. The folding device 100 can fold the flexible member 101 multiple times through the pulling member, the first folding member 30 and the second folding member 40. It can automatically perform multiple foldings, the folding speed is faster, the folding process is simplified, the folding efficiency is improved, and the production cost is reduced.
