Description

Technical Field

[0001] The utility model relates to an automatic belt threading machine and a traction mechanism applied to the belt threading machine. Background Art

[0002] The automatic strapping machine is a derivative device of the packaging equipment, especially for large-scale overhead packaged goods. The flip head set by it drives the strapping tape to bypass the packaged goods for a circle, and then the packaging machine is used to package. The automatic strapping machine includes a body, a mobile bracket, and a flip head. The limiting belt is connected between the body and the mobile bracket, and the driving chain is connected between the flip head and the body. At the same time, the flip head is also connected to one end of the strapping tape. The body has a cavity, which stores the driving chain and the limiting belt. The driving chain is driven by a motor to retract and release, and the flip head is driven forward and backward through the driving chain, and the flip head drives the mobile bracket to move along the ground. When the mobile bracket is driven forward and drives out of the packaged object from the bottom, the flipping of the flip head is manually braked by the limiting belt to brake the mobile bracket. The flip head is guided by the limit fit, and flips upward under the drive of the drive chain, then rises and leaves the mobile bracket, and then bypasses the packaged object under the drive and guidance of the drive chain. The above flip head scheme will affect the flipping success rate of the flip head as the parts wear out. Utility Model Content

[0028] With reference to the accompanying drawings, the utility model provides a traction mechanism, including a mobile carrier, a drive chain 2, and a strapping connection structure; the traction mechanism is provided with a traction member 3, and the traction member 3 is provided with the strapping connection structure 31, the traction member 3 is connected to one end of the drive chain 2, and can be driven to move by the drive chain 2; an angle adjustment mechanism and a drive component thereof are provided on the mobile carrier, and the drive component can be a drive motor 40 with a deceleration mechanism, the angle adjustment mechanism can be driven to rotate by the drive motor 40 to adjust the angle, the traction member 3 can be detachably connected to the angle adjustment mechanism, and before being detached from the angle adjustment mechanism, it is carried on the mobile carrier and can be driven by the angle adjustment mechanism to rotate to a flipping angle, for example, after passing through the packaged object from the bottom, the angle adjustment mechanism rotates more than 90 degrees under the drive of the drive motor 40, so that the traction member 3 also rotates more than 90 degrees, at this time, under the drive of the drive chain 2, the traction member 3 performs a strapping movement upward and is detached from the angle adjustment mechanism.

[0029] The driving motor 40 is powered by a battery 41. The mobile carrier is provided with a battery installation position for placing the battery 41. The mobile carrier is provided with a driving component installation position, and the driving motor and the reduction mechanism are arranged on the driving component installation position. The battery installation position and the driving component installation position are respectively located on both sides of the angle adjustment mechanism.

[0030] The battery and the motor are respectively located on both sides of the angle adjustment mechanism, which can balance the mobile vehicle and facilitate the stability of the movement path of the traction member 3.

[0031] For the installation position, the mobile carrier is provided with partitions on both sides of the angle adjustment mechanism, which separate the angle adjustment mechanism from the battery and the motor to improve safety. At the same time, the partition can serve as a rotation support for the angle adjustment mechanism. The first side of the angle adjustment mechanism is rotationally supported on the first side partition 111, and the second side is connected to the drive motor 40 through the gear 42. The first side of the angle adjustment mechanism is rotationally supported on the second side partition 112.

[0032] The mobile carrier includes a chassis 1, on which front and rear travel rollers 12 are arranged; the installation position of the battery 41 is located between the front and rear travel rollers 12. The chassis 1 is also provided with a limiting structure (such as a limiting plate 13 or a limiting rod) and a limiting belt connection structure 14, the limiting structure is located behind the angle adjustment mechanism, and the mobile carrier forms a hole 15 for the traction member and the drive chain to pass through below the limiting plate, so as to guide the forward and backward movement of the drive chain 2.

[0033] The angle adjustment mechanism adopts a frame 4 that penetrates front and back. The traction member 3 and the drive chain 2 pass through the through-hole 43 on the frame 4 to guide the forward and backward movement of the drive chain 2. The hole 15 and the through-hole 43 form a guide channel for the forward and backward movement of the drive chain 2.

[0034] The forward and reverse movement of the mobile vehicle is driven by the drive chain 2 through the traction member 3. A detachable driving matching structure is provided between the traction member and the mobile vehicle, so that before the traction member flips over, the traction member 3 pushes the mobile vehicle forward, and after the traction member 3 flips over, the traction member 3 is disengaged from the pushing effect on the mobile vehicle. The traction member 3 is retracted by retrieving the drive chain 2, and when the traction member 3 is threaded and returned to the mobile vehicle and retracted, it can push the mobile vehicle back.

[0035] The driving cooperation structure includes a limiting structure (limiting block 32) located on the traction member, a first limiting structure (limiting block 16) located on the mobile carrier, and a second limiting structure located on the angle adjustment mechanism. The cooperation between the limiting block 32 and the limiting block 16 pushes the mobile carrier forward, and the cooperation between the limiting block 32 and the second limiting structure pushes the mobile carrier back.

[0036] Preferably, the second limiting structure is located on the angle adjustment mechanism, so that it can be set as a guide structure to facilitate the upward guidance of the traction member and the entry into the angle adjustment mechanism during recovery. For example, a guide groove 44 with a forward opening and a guiding function for the limiting block 32 is used to push the groove bottom 441 to push the mobile carrier back.

[0037] When it is necessary to flip, the driving motor 40 drives the angle adjustment mechanism to rotate to the set angle, and at the same time, the traction member is also rotated to the corresponding angle, which can be adjusted by setting the motor, so that the traction member 3 can rise obliquely at the best angle. At this time, the limit block 32 and the limit block 16 are separated, and the mobile carrier loses the propulsion effect of the drive chain 2.

[0038] Based on the above scheme, the start timing of the drive motor 40 can be precisely controlled, for example, by a controller that can receive a signal corresponding to the running length of the drive chain. The signal can be realized based on a counter, and the counter counts the number of rotations of the sprocket 21 of the drive chain. The count can correspond to the running length of the drive chain 2. When the release length of the drive chain 2 reaches the set length, that is, the mobile carrier has driven out of the packaged object from the bottom, the drive motor 40 is controlled to start working, and the angle adjustment mechanism is driven to adjust the angle. The working time of the drive motor 40, that is, the rotation angle of the angle adjustment mechanism, can be realized based on a limit sensor with a fixed or adjustable installation position, which includes a first limit sensor 171 and a second limit sensor 172, which respectively correspond to the two rotation limit positions of the angle adjustment mechanism, and are used to provide a signal to stop the drive motor 40 and restart the drive chain 12. Reference numeral 46 is a trigger member fixedly connected to the frame 4 and working in cooperation with the first limit sensor 1 and the second limit sensor 172.

[0039] The automatic tape threading machine includes a body 100 , the limiting belt 101 is connected between the mobile carrier and the body 100 , and the other end of the driving chain is connected to a driving device installed on the body 100 , and the driving device may include a sprocket 21 and a sprocket driving motor 22 .

[0040] Furthermore, the present invention also provides a mobile vehicle recovery guide structure, a mobile vehicle parking position, and a battery charging seat at the bottom of the body. When the drive chain is recovered and the mobile vehicle is dragged back to the body, it is accurately returned to the parking position of the mobile carrier in the body through the guidance of the guide mechanism, and the battery charging part on the mobile vehicle can accurately contact the charging seat, so that the battery can be automatically charged.

[0041] In the figure, reference numeral 200 is a strapping belt reel. One end of the strapping belt is connected to the strapping belt connection structure 31, and can go around the strapping object along with the traction member 3.
