AI Technical Summary
The core of existing packing machines is too large in width, making it difficult to achieve a reasonable structural layout. In particular, the power drive of the strapping mechanism needs to be coordinated with the movement of other mechanisms.
The tape feeding assembly is oscillating. The axial forward and backward movement and oscillation of the tape feeding assembly are controlled by the first and second drive parts respectively. Combined with the second control cam and the reset mechanism, the tape feeding part moves away from and towards the oscillation axis, decomposes the driving power, and reduces the size of the movement in the width direction.
Independent drive of the strapping mechanism was achieved, reducing the width dimension of the strapping machine core, optimizing the structural layout, and improving motion coordination.

Abstract
Description
Technical Field
[0001] This utility model relates to a packing machine, and more particularly to a strapping mechanism in a packing machine. Background Technology
[0002] A strapping machine includes a core mechanism, which comprises a heat-bonding mechanism, a strap-topping mechanism, and a strap-cutting mechanism. A series of cams mounted on the core shaft are driven by a core motor to control the movement of these mechanisms, thereby securing, cutting, and bonding the strapping. One type of strapping machine uses a strap-reaming mechanism to wrap the strapping around the item. This strap-reaming mechanism also requires power to move around the object while simultaneously moving back and forth relative to it.
[0003] The core motor needs to control components that move up and down, such as the top belt mechanism and the belt cutting mechanism, as well as components that move forward and backward, such as the heat sealing mechanism. It also needs to control all the actions of the belt handling mechanism. The core motor's dimensions in the width direction of the packing machine are too large and need to be optimized.

[0023] The packing machine includes a core mechanism. Referring to the attached drawings, the core mechanism is equipped with a core motor 101, a core frame 102, and a core shaft 103. The core shaft 103 is connected to the core motor 101. The core mechanism is equipped with the strapping mechanism described in this utility model.
[0024] The strapping mechanism includes a swingable strapping assembly, which can move back and forth along the axial direction. The strapping assembly includes a swing arm 1 and a strapping component 2 movably connected to the swing arm 1, allowing the strapping component 2 to move away from and towards the swing axis, i.e., the center line of the swing axis 11. The strapping mechanism includes a first driving part and a second driving part. The first driving part includes a first driving motor, which in this embodiment is the core motor 101, but a separate cylinder or other driving motor can also be used. The second driving part includes a second driving motor and a second control part. The second driving motor can be an electric motor, named the second driving motor 3 in this embodiment. The second driving motor 3 is arranged perpendicularly to the core motor 101 and can be arranged in the thickness direction of the packing machine. Preferably, the second driving motor 3 is arranged on the side of the core shaft, opposite to the side of the sliding plate arm in the core. In the accompanying drawings, reference numeral 300 represents the core sliding plate, and reference numeral 301 represents the sliding plate arm. The axial forward and backward movement of the tape feeding assembly and the oscillation of the tape feeding assembly are driven by different drive motors. Furthermore, when the tape feeding assembly oscillates, the second control unit controls the tape feeding component to move away from and towards the oscillation axis.
[0025] The second control section includes a second control cam 4 disposed outside the movement shaft. The second control cam 4 is connected to a mechanism that can raise and lower its cam surface, allowing its cam surface to be raised and lowered. The strap guide 2 is connected to a second reset mechanism and a second control cam engaging component 23, so that the second control cam engaging component 23 and the second control cam are tightly engaged. The second reset mechanism uses a reset spring 24, arranged between the rocker arm 1 and the strap guide 2. The strap guide includes a horizontal portion 21 and a vertical portion 22. The horizontal portion 21 is used for strap guiding, and the vertical portion 22 is used for an insert-type sliding connection with the rocker arm 1. The second control cam engaging component 23 is connected to the vertical portion 22, and the vertical portion 22 is also connected to the reset spring 24. The second control cam engaging component 23 may be a roller.
[0026] The first drive section includes a third control section and a third reset mechanism. The third control section and the third reset mechanism cooperate to adjust the height of the cam surface of the second control cam 4. The lowest descending position of the cam surface of the second control cam 4 is lower than the lowest position of the second control cam mating component 23, causing the belt conveyor assembly to return to above the second control cam via axial movement. This then drives the second control cam 4 to rise, raising the cam surface to the working position and contacting the second control cam mating component 23. The third reset mechanism uses a reset spring 5, arranged between the second control cam and the movement frame 102.
[0027] The mechanism for raising and lowering the cam surface height includes a swing arm 6, which is rotatably mounted on the movement frame 102. The swing arm 6 has a lifting working part for lifting the second control cam 4. The swing arm 6 also has a controlled part that is controlled by a third control part. The second control cam 4 is rotatably mounted on the movement frame 102, increasing the speed and sensitivity of height adjustment. The third control part includes a third control cam 60, which is fixed to the movement shaft 103. The height of the second control cam 4 is higher than the height of the third control cam 60. The lifting working part can be a roller 61, and the controlled part can be a roller 62.
[0028] Furthermore, the mechanism for raising and lowering the height of its cam surface can be a device that directly acts on the second control cam, such as a cylinder. Alternatively, the drive of the third control part can be a motor other than the core motor, and the second control cam 4 can also adopt other movable mounting structures such as sliding mounting, thereby enabling adjustment of the height of its cam surface.
[0029] Furthermore, a vertical slot 41 can be provided on the second control cam 4, and the return spring 5 is movably connected to the vertical slot 41 via the insert rod 42, thereby movably connecting the second control cam 4 to the third reset mechanism.
[0030] The tape feeding mechanism also includes a sliding table 7. The tape feeding assembly and the second drive motor 3 are mounted on the sliding table 7. The sliding direction of the sliding table 7 is the axial forward and backward movement direction of the tape feeding assembly. The sliding table 7 is equipped with a first reset mechanism. The core motor 101 and the first reset mechanism cooperate to drive the sliding table and the structure located on the sliding table 7 (including the second drive motor 3 and the tape feeding assembly) to slide forward and backward. The first driving part includes a first control part, which controls the forward and backward movement of the sliding table. The first control part includes a first control cam 70, which is fixed on the core shaft 103. The sliding table is provided with a controlled component that cooperates with the first control cam 70, such as a roller 71. The sliding table 7 can also be driven by other motors, such as cylinders.
[0031] The first reset mechanism uses a reset spring 8, which is arranged between the sliding table 7 and the mechanism frame 102; the mechanism frame 102 is provided with a guide rail 104 for the sliding table 7, and the sliding table 7 is slidably connected to the guide rail 104 through a slider 72.
