The packing machine mainly includes a tape threading mechanism for conveying and storing packing tapes, a machine head device for ironing, sticking and shearing packing tapes, and a frame device for the packing tapes to wind around the object to be tied. In the patent No. CN201120244505.4, named: A new tape threading mechanism for a packing machine, it discloses a tape threading mechanism for a packing machine. This structure is a common packing device in the current market. This utility model records a fixed track and a tape retracting chamber cover plate, and the two cooperate to work. When the packing tape enters the tape threading track of the packing machine, the tape retracting chamber cover plate and the fixed track are in a buckled state. In this way, the packing tape can enter the working machine head of the packing machine upward. Subsequently, the tape retracting chamber cover plate is driven by a cylinder to move and separate from the fixed track. When the subsequent coiled packing tape is conveyed into the packing machine again, the redundant packing tape will be stored in the tape storage chamber on one side. However, for this kind of tape threading mechanism, its overall structure has many components, high manufacturing cost, and the tape retracting chamber cover plate occupies a large area in the packing machine, which seriously squeezes the space inside the packing machine.

[0014] In order to be able to more clearly understand the above objects, features, and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0015] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0016] Such as Figure 1-2As shown in the figure, the improved tape threading mechanism of the packing machine in this embodiment includes a middle guide plate 1 arranged on the packing machine frame. Upper and lower guide plates 2 and 3 are respectively arranged at the upper and lower ends of the middle guide plate 1. A first gap 4 is arranged between the upper guide plate 2 and the middle guide plate 1, and a second gap 5 is arranged between the lower guide plate 3 and the middle guide plate 1. A rotatable guide plate 6 is arranged on the packing machine frame at a position corresponding to the left end of the middle guide plate 1. A third gap 7 is arranged between the guide plate 6 and the middle guide plate 1. The first gap 4, the second gap 5, and the third gap 7 communicate with each other to form a tape passing gap.

[0017] The lower end of the guide plate 6 is installed on the left side of the lower guide plate 3 through a rotating shaft 8, and the upper end of the guide plate 6 is attached to the position corresponding to the left side of the upper guide plate 2 after being flipped.

[0018] A motor (not shown in the figure) is also arranged on the packing machine frame at a position corresponding to the rotating shaft 8. The driving shaft of the motor is fixedly connected to the rotating shaft 8, and the guide plate 6 rotates along the rotating shaft 8 under the drive of the motor.

[0019] The left end of the middle guide plate 1 is a semi-circular structure, and the guide plate 6 is an arc-shaped structure adapted to the semi-circular structure of the middle guide plate 1.

[0020] The upper guide plate 2, the middle guide plate 1, and the lower guide plate 3 are all fixedly arranged on the packing machine frame through screws.

[0021] Preferably, the upper guide plate 2, the middle guide plate 1, the lower guide plate 3, and the guide plate 6 are all made of stainless steel.

[0022] As Figure 3 shown, in the second embodiment, an anti-collision block 9 is arranged on the side of the guide plate close to the left end of the upper guide plate 2. The anti-collision block 9 can prevent the upper end of the guide plate 6 from rigidly colliding with the left end of the upper guide plate 2, thereby ensuring that each component will not be damaged during operation and extending the service life of the equipment.

[0023] The working principle of the present utility model is as follows: First, by controlling the motor to drive the guide plate 6 to rotate, the upper end of the guide plate 6 is rotated to a position close to the upper guide plate 2, so that each gap is connected to form an over-belt gap. The wound packing belt is conveyed to the second gap 5 between the lower guide plate 3 and the middle guide plate 1 through the belt feeding wheel set, and then turns along the third gap 7 and enters the first gap 4 between the upper guide plate 2 and the middle guide plate 1. Then, the packing belt is conveyed to the head and frame structure of the packing machine through other belt feeding wheel sets for packing operations. While the packing belt is performing the packing operation, the motor will start again and control the guide plate 6 to rotate again. At this time, the upper end of the guide plate 6 is rotated to a position away from the upper guide plate 2, so that the third gap 7 is destroyed, and further the first gap 4 and the second gap 5 cannot be connected. The subsequent conveyed packing belt will be stored in the belt storage bin. When the packing machine performs the packing operation again, the packing belt in the belt storage bin will be sent out for packing operations. After that, the guide plate 6 stops working until a new wound packing belt is replaced.

[0024] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
