[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 - 9 shown, this embodiment discloses an automatic two-way pull head threading machine, which includes a tape feeding device 1, a loading device 2, a feeding chute 3, a material transferring device 4 and a tape threading device 5. One end of the tape feeding device 1 is docked with one end of the tape threading device 5. One end of the feeding chute 3 is docked with the loading device 2, and the other end is opposite to the tape threading device 5, and is used to sequentially send the sorted pull heads to one side of the tape threading device 5. The material transferring device 4 sequentially pushes the pull heads to the lower part of the tape threading device 5. The material transferring device 4 is arranged on the side of the tape threading device 5. It further includes a reversing device 6, which is arranged under the tape threading device 5. The material transferring device 4 pushes the pull heads from the feeding chute 3 to the reversing device 6. The reversing device 6 is used to adjust the orientation of the pull heads and send the pull heads to the tape threading device 5 for the pull head threading action, so that the tape of the tape feeding device 1 can penetrate from both ends of the pull head to complete the penetration action, realizing the tape threading and reversing of the pull heads.

[0032] Furthermore, the tape threading device 5 includes a slide table 51, a base plate 52, a tape threading table 53, a tape pressing device 54 and a tape threading and pulling assembly 55. The slide table 51 is arranged along the moving direction of the tape, and can drive the tape threading device 5 as a whole to move to adjust the relative position between the pull head and the tape threading device 5. The base plate 52 is slidably connected to the slide table 51. The tape threading and pulling assembly 55 is arranged on the base plate 52 and is used to fix the tape, split the tape and fix the pull head. The tape threading table 53 is arranged on one side of the tape threading and pulling assembly 55 and is used to fix the pull head. The tape pressing device 54 is arranged on the tape threading table 53 and is used to press one end of the tape to fix the tape. The tape pressing device 54 is divided into two parts arranged on both sides of the tape threading table 53.

[0033] Further, the commutation device 6 includes a gripper 61, a turntable 62, and a lifting seat 63. The lifting seat 63 is arranged on the seat plate 52 and can move simultaneously with the tape threading device 5, ensuring that the positions of the upper pull head and the threading tape are the same, improving the accuracy of the actions of the upper pull head and the threading pull head. The turntable 62 is arranged on the lifting seat 63 and is used to drive the pull head to rotate for commutation. The gripper 61 is arranged on the turntable 62 and is used to grip the pull head. The gripper 61 moves upward under the drive of the lifting seat 63, sending the picked pull head to the pull head threading position. The top end of the pull head abuts against the pull head fixing block 551, which can position and press the pull head.

[0034] Furthermore, the center of the gripper 61 coincides with the rotation center of the turntable 62, enabling the pull head to commutate in place, reducing the moving actions, and improving the speed and accuracy of commutation.

[0035] Furthermore, the gripper 61 includes a left jaw 611, a right jaw 612, and a hook 64. The left jaw 611 is fixedly connected to the turntable 62, the right jaw 612 is slidably connected to the turntable 62. A pull head clamping position is formed between the left jaw 611 and the right jaw 612. The hook 64 is rotatably connected to the left jaw 611 and the hook 64 passes through the left jaw 611 and extends into the pull head clamping position. The material transfer device 4 pushes the pull head from the side to the pull head clamping position, and the left jaw 611 and the right jaw 612 clamp the pull head. After the pull head is clamped, the side with the pull ring faces downward. One end of the hook 64 extends into the pull head, and the hook 64 is driven by a cylinder to rotate, which is used to trigger the lock of the pull head, and can open the lock during threading the pull head, facilitating reverse threading.

[0036] Preferably, the part of the seat plate 52 close to the pull head clamping position is hollowed out. The cross-section of the seat plate 52 is U-shaped, and the hollowed-out part is used for the material transfer device 4 to send the pull head to the gripper 61, and the threading assembly 55 and the gripper 61 can be aligned, facilitating the use of the threaded pull head.

[0037] Further, the threading assembly 55 includes a pull head fixing block 551, a first tape separating block 552, a second tape separating block 553, and a pull head sensing rod 554. The pull head fixing block 551 is arranged on the seat plate 52. The first tape separating block 552 and the second tape separating block 553 are respectively telescopically connected to both sides of the pull head fixing block 551. The pull head sensing rod 554 is arranged to slide through the pull head fixing block 551. The first tape separating block 552 and the second tape separating block 553 can act independently and are used to separate the tapes on both sides of the pull head respectively, facilitating the use of the tape when threading different orientations of the pull head. The pull head sensing rod 554 is slidably connected in the pull head fixing block 551, and one end of it moves upward after contacting the pull head, which is used to sense whether the pull head is in place, ensuring the accuracy of the threading pull head action.

[0038] Preferably, the threading and pulling assembly 55 further includes a sensor 56, which is arranged at one end of the slider fixing block 551 away from the slider. One end of the slider sensing rod 554 passes in front of the sensor 56. The sensor 56 is non-contact type and can transmit a signal to the control box 9 when the slider sensing rod 554 slides upward, so as to trigger the subsequent slider threading action and prevent the belt from being threaded empty.

[0039] More preferably, it further includes a control box 9, which is arranged on one side of the feeding device 2 and is used to directly observe the execution of the slider threading action and adjust the speed of the slider threading action.

[0040] More preferably, it further includes a lower chain device 7, which is arranged at the other end of the belt threading device 5. The lower chain device 7 is composed of a belt and a synchronous pulley and is used to provide the power for the belt to move outward.

[0041] More preferably, the belt feeding device 1, the feeding device 2, the feeding slideway 3, the material shifting device 4 and the belt threading device 5 are all installed on the chassis 8. The slide table 51 of the belt threading device 5 is installed inside the chassis 8, and electrical and pneumatic components are also installed inside the chassis 8, which is convenient for overall movement.

[0042] The working process of this automatic two-way slider threading machine is as follows:

[0043] The sliders are sorted by the feeding device 2 and then enter the feeding slideway 3. The sliders move to the movable clamping table 31 in sequence through the feeding slideway 3. The push rod 42 drives the push arm 41 to extend forward to send the slider on the movable clamping table 31 below the threading and pulling assembly 55. The left clamping jaw 611 opens, the lifting seat 63 drives the gripper 61 to rise to the position of the slider. The left clamping jaw 611 slides and closes to clamp the slider. The lifting seat 63 continues to rise to move the slider to the belt threading position for the slider, so that the top of the slider contacts the slider fixing block 551 to complete the fixation. The belt feeding device 1 feeds the belt into the belt threading position for the slider to complete the belt threading of the slider. After completing a belt threading action, the gripper 61 descends to receive the slider, and the turntable 62 drives the gripper 61 to rotate in place to complete the slider commutation. The lifting seat 63 drives the gripper 61 to the belt threading position for the slider again to complete the belt threading of the slider in the other direction.
