Referring to FIG. 4, FIG. 5 and FIG. 6, the tape transport bundling mechanism 1 of the present invention comprises a side wall (not shown), a bundling assembly mounted on the side wall, and the bundling assembly includes a guide rail 6 and a guide rail entrance. Channel 8, the paper feed roller 7 on the channel, the tongue 10 on the inner side of the guide rail, the hot head 9 disposed opposite the tongue, a plurality of sub-guide wheels 11 distributed inside the guide rail, and a tray holder assembly on one side of the strap assembly The paper tray holder assembly includes a paper tray holder 2 and a paper tray rotating shaft 3 located at a center of the paper tray holder, rotatably fitted to the paper tray 4 of the paper tray holder assembly, and the paper tape rotatably disposed outside the paper tray holder assembly is tightened The device 13, when the paper tape is conveyed, the tape tensioning device is separated from the outer casing of the paper tray, and when the paper tape is initially and stopped, the paper tape tensioning device presses the outer casing of the paper tray.

The specific working mode of the paper tape conveying and bundling mechanism of the present invention is that the paper tape 12 wound on the paper tray 4 is passed through the paper tape tensioning device 13 in advance, passes through the paper guiding roller 5, enters the channel 8, and is fed by the paper feeding wheel 7. Clamping, when a paper tape is required for binding articles such as banknotes, the motor connected to the paper feed roller 7 is opened, the paper feed roller 7 is rotated toward the side of the guide rail 6, and the paper tape 12 is conveyed forward, and the paper tape 12 is conveyed. In an instant, the tape tensioning device 13 is separated from the outer casing of the paper tray, and then the paper tape 12 passes through the gap between the heat head 9 and the pressure tongue 10, and a paper roll is formed inside the guide rail 6 under the driving of the auxiliary guide wheel 11, Prepare for the strapping action. When the bundling action is stopped, the tape stops conveying, and the tape tensioning device 13 instantaneously contacts the outer rim of the paper tray 4, eliminating the inertial force of the paper tray itself to stop the paper tray from rotating. The paper tape tensioning device effectively solves the problem of loose paper or paper tape mess.

Compared with the prior art, the use of the pressing device to continuously press the outer surface of the paper tray to eliminate the rotation of the paper tray under the action of its own inertial force, the technical solution of the present invention is separated from the paper tray by the paper tape tensioning device during the paper tape conveying process. The outer casing reduces the load on the paper feeding motor; it also reduces the wear on the paper tray.

As an improvement of the tape transport bundling mechanism of the present invention, referring to FIG. 4 to FIG. 7, the tape tensioning device 13 includes a rotating shaft 14 fixedly connected to the side wall at one end, and the rotatably set a pressing plate 130 on the rotating shaft, a pressing member 16 for providing a pressing force to the pressing plate, a contact end portion 131 at one end of the pressing plate contacting the outer side of the paper tray, a hollow groove 132 opening at the other end of the pressing plate, and a winding connection between the two side walls of the empty groove The piece 150, through which the tape 12 is conveyed around the wrap 150 to the strapping assembly. When transporting In the case of a paper tape, the paper tape 12 lifts the winding member 150, and the contact end portion 31 of the pressure plate member 130 is separated from the outer side of the paper tray 4. When the conveyance is stopped, the contact end portion 31 is instantaneously pressed by the pressing member 16. Tightening the outer cymbal of the paper tray 4 eliminates the inertial force of the paper tray itself, and the paper tray stops rotating instantaneously.

The following is a comparison of the load of the paper feed motor of the prior art in which the pressing device continuously presses the outer side of the paper tray and the paper web tensioning device of the present invention:

Refer to the force diagram of Figure 9a. In the prior art, the output torque of the motor that is continuously pressed against the outer casing of the paper tray is: M1=M. + FR (where Ml: the torque required for the motor to transport the tape in the prior art;

M ₀ : static force of the paper tray; μ: friction coefficient between the pressing device and the outer cymbal of the paper tray; F: minimum force required to press the outer cymbal of the paper tray; R: outer diameter of the paper tray), usually due to the action of F The line passes through the axis of the paper tray, so F does not create a resistance distance.

Referring to the force diagram of FIG. 9b, the output torque of the motor in the technical solution of the present invention is: M2=M. +FS (where S is the distance between the center of rotation of the platen and the outer contact point of the paper tray), the output torque of the motor of the present invention includes the torque required to convey the paper tape and the paper tape is tightened by the tape tensioning device Torque, and the tightening torque of the tape tensioning device is Ft x L (where Ft is the pulling force of the tape tensioning device on the paper tape, and L is the distance from the pulling end of the tape tensioning device to the rotating shaft) ), as long as the tightening torque of the tape tensioning device makes the tape tensioning device out of the outer disk of the paper tray, the tightening torque Ft XL of the paper tape tensioning device is equal to FS.

The difference between the output torque M1 of the prior art motor and the output torque M2 of the motor of the present invention is that the difference between the two is μΐ and S, and the S of the present invention is smaller than μΐ, and the usual design of the technician is also S less than μΐ. Therefore, the present invention can effectively reduce the load of the paper feed motor relative to the prior art. Secondly, the technical solution of the present invention has an effect of reducing the load of the paper feeding motor as the diameter of the paper tray is increased.

The hole 134 is more specifically a U-shaped hole. When the paper tape is conveyed, the winding member is lifted by the paper tape, and the connecting end of the tension spring is in the hole, and the pressing force is not supplied to the pressure plate, so that the load of the conveying motor is not increased; when the paper tape stops conveying, the winding member When it is dropped, the tension spring contacts the hole wall to tension the pressure plate 130, and the contact end portion 131 presses the outer surface of the paper tray.

Further, the pressing member 16 is a compression spring which is attached to one side of the end portion 131 of the pressure plate 130 contacting the end portion 131 and opposite to the paper tray 4. The pressure contact provided by the compression spring presses the contact end of the pressure plate against the outer rim of the paper tray.
