[0002] The automatic strapping machine is a derivative of the strapping equipment, especially for large-scale overhead strapping goods. The flip head is used to drive the strapping belt to go around the strapping goods for a circle, and then the strapping machine is used to strap them. The automatic strapping machine includes a machine body, a mobile bracket, and a flip head. The machine body and the mobile bracket are connected by a connecting belt, and the flip head and the machine body are connected by a driving chain. At the same time, the flip head is also connected to one end of the strapping belt. The machine body has a cavity in which a drive chain and a connecting belt are stored. The drive chain is driven by a motor to be retracted and released, and the drive chain drives the flip head forward and backward, and the flip head drives the mobile bracket to move along the ground. The connecting belt is a sheet belt with a certain toughness. The connecting belt is released forward as the mobile bracket moves forward, and is stored back in the machine body cavity as the mobile bracket moves backward. When the mobile bracket moves forward into place, the mobile bracket is braked by clamping the connecting belt. In order to adapt to the different release lengths of the mobile bracket, a plurality of holes are provided on the connecting belt for cooperation with the active latch. However, this greatly affects the firmness of the connecting belt, making it easy to break, which is not conducive to the frequent use of the automatic tape threading machine. Utility Model Content

[0020] Refer to the attached drawings. The automatic strapping machine includes a body 100 and a mobile carrier 1, on which a flip head 3 is carried, and the flip head 3 is connected to a strapping belt, driving the strapping belt to go around the packaged goods for a circle, and then the strapping machine performs the packaging. A drive chain 2 is connected between the flip head 3 and the body 100, and the drive chain is driven by a motor to retract and release, and the flip head is driven forward and backward through the drive chain, and the flip head 3 drives the mobile carrier 1 to move along the ground, and after reaching the flipping point, the flip head 3 flips upward.

[0021] The utility model provides a traction limiting device, wherein one end of the connecting belt is movably connected to the body 100 of the automatic tape threading machine, and the other end is connected to the moving carrier 1 of the automatic tape threading machine. The connecting belt 101 is a sheet belt with certain toughness.

[0022] A limit block 6 is provided on the connecting belt 101, and more than three locking mechanisms 5 are provided on the body of the automatic threading machine along the running route of the connecting belt 101 on the body. The locking mechanism includes a movable locking member matched with the limit block and a driving motor 51 thereof.

[0023] A guide slope 61 is provided on the back side of the limit block 6 to facilitate smooth reverse retraction movement.

[0024] The movable lock member of the locking mechanism is a rotating member, and the rotating member includes a connecting portion 52 and a baffle 53, and the connecting portion 52 is connected to the output shaft 54 ​​of the driving motor 51. The baffle 53 moves between a first position and a second position by rotating. When the baffle 53 is located at the first position, the baffle 53 abuts against the limit block 6, and when the baffle 53 is located at the second position, the baffle 53 gives way to the limit block 6. The movable lock member can also be set as a linear motion component.

[0025] The locking mechanism further includes a mounting member 56 , and the mounting member 56 is fixedly connected to the body 100 ; the connecting portion is provided with a connecting hole, and the output shaft 54 ​​passes through the mounting member 56 and enters the connecting hole to be fixedly connected to the connecting portion.

[0026] The machine body is provided with a vertical plate 103 and a mounting plate 104 facing each other, and a groove 105 is provided on the mounting plate 104 and the vertical plate 103 to guide the operation of the connecting belt 101. The two sides of the connecting belt 101 are respectively inserted into the groove 105 on the same side as each side, and the portion of the connecting belt 101 located outside the groove is provided with the limit block 6. The mounting piece 56 is connected to the mounting plate 104 to mount the drive motor 51 on the mounting plate 104.

[0027] The connection part 52 may be configured to be shaft-shaped, and bearings 55 of the connection part 52 are respectively disposed on the vertical plate 103 and the mounting plate 104 .

[0028] The vertical plate 103 is also provided with a notch 106 communicating with the groove 105 for the connecting portion 52 and the baffle 53 to penetrate.

[0029] The vertical plate 103 and the mounting plate 104 are also the front and rear panels of the machine body 100 . A cavity of the machine body is formed between the vertical plate 103 and the mounting plate 104 for the connection belt 101 and the driving chain 2 to run and store.

[0030] For the automatic strapping machine, the connecting belt 101 is connected to the bottom of the mobile carrier 1, and the driving chain 2 drives the mobile carrier 1 and the connecting belt 101 to move together, passing through the bottom of the packaged goods. When the mobile carrier 1 moves forward to the stop position, the locking mechanism rotates and limits the movement of the connecting belt 101 (blocking the limit block 6). Since the connecting belt 101 is connected to the mobile carrier 1, the movement of the mobile carrier 1 is also restricted. A rubber pad can be added to the limit block 6 to reduce the impact force. The rotation of the locking mechanism at different positions can determine the extension length of the connecting belt 101.

[0031] The driving motor 51 of each locking mechanism can use a small motor to drive the rotating part to rotate. The small motor has low cost. Moreover, when the extension length of the connecting belt 101 needs to be adjusted, the connecting belt 101 can be pressed against the locking mechanism at different positions. In this case, the damage rate of the locking mechanism is low.
