the feeding and returning belt pressure adjusting rod 611 is connected with a feeding and returning belt pressure roller 610 through a feeding and returning belt eccentric shaft 612, one end of the feeding and returning belt pressure adjusting rod 611 far away from the feeding and returning belt pressure roller 610 is provided with a second pressure adjusting driving mechanism 613 for driving the feeding and returning belt pressure adjusting rod 611 to rotate, and the feeding and returning belt pressure roller 610 is movably arranged on the side edge of the belt guide groove 608 through the feeding and returning belt pressure adjusting rod 611;
the second pressure adjusting driving mechanism 613 is an electromagnet or an air cylinder, in this embodiment, the second pressure adjusting driving mechanism 613 is an electromagnet, and the feeding and retracting belt pressure adjusting rod 611 drives the feeding and retracting belt pressure roller 610 to deflect, so as to adjust the clamping force between the feeding and retracting belt pressure roller 610 and the feeding and retracting belt main wheel 609 on the packing belt, thereby realizing high-speed and stable conveying of the packing belt.
Further, the belt feeding and retracting tightening mechanism 600 further comprises a belt inlet 614 of the machine core arranged on the mounting base plate 601, the belt inlet 614 of the machine core is arranged on one side, away from the arc-shaped belt path, of the auxiliary feeding and retracting large wheel 602 and the auxiliary feeding and retracting pressing wheel 603, the belt inlet 614 of the machine core comprises two groups of guide blocks 615, an arc-shaped guide groove 616 is formed between the two groups of guide blocks 615, and a packing belt penetrates into the belt inlet 614 of the machine core from the arc-shaped guide groove 616.
Specifically, when the tape is fed for the first time, the tape head of the packing tape stored in the tape storage bin enters the gap between the auxiliary feeding and retracting bull wheel 602 and the auxiliary feeding and retracting pinch wheel 603 through the arc-shaped guide groove 616 formed by the tape inlet 614 of the machine core, and enters the arc-shaped tape channel formed by the feeding and retracting belt crescent guide plate 607 and the auxiliary feeding and retracting bull wheel 602, so that the action of penetrating the packing tape into the machine core is completed. The auxiliary feeding and withdrawing belt motor 617 is started to drive the auxiliary feeding and withdrawing main wheel 602 to rotate in the tangential angle direction of the penetrating of the packing belt, the first pressure adjusting and driving mechanism 606 synchronously drives the tightening pressure adjusting rod 604 to push the auxiliary feeding and withdrawing pressure wheel 603 to press the packing belt on the auxiliary feeding and withdrawing main wheel 602, so that in the rotating process of the auxiliary feeding and withdrawing main wheel 602, the packing belt is pushed to be conveyed forwards along an arc-shaped belt path and then enters a belt path guide groove 608, and the gap between the feeding and withdrawing belt main wheel 609 and the feeding and withdrawing belt pressure wheel 610 is extruded. At this time, the tightening pressure adjusting rod 604 moves in the reverse direction to drive the auxiliary feeding and retracting pressure wheel 603 to separate from the auxiliary feeding and retracting bull wheel 602, thereby completing the first feeding and conveying of the packing belt. The subsequent tape is fed forward along the closed loop-shaped tape path 70 by the high-speed rotation of the tape feeding and discharging main wheel 609 and the tape feeding and discharging pressing wheel 610.
The main belt feeding and withdrawing wheel 609 and the belt feeding and withdrawing pressure wheel 610 continuously press against the two sides of the packing belt, the auxiliary large belt feeding and withdrawing wheel 602 continuously rotates for a unit belt feeding time under the control of a PLC program, and the belt drives the main belt feeding and withdrawing wheel 609 and the belt feeding and withdrawing pressure wheel 610 to push the packing belt to feed forward at a high speed and enter the right side belt inserting port of the bundling machine core 10. When the strapping tape is reversely withdrawn, the strapping tape is not easy to fall out from the tape feeding and withdrawing mechanism because the strapping tape is limited by the arc-shaped structure of the arc-shaped tape channel, thereby avoiding the phenomenon that the strapping tape falls off in the strapping and packaging process.
When the tape is fed for the first time, the tape head is not fed in place due to insufficient tape feeding time, insufficient straightness of the tape head of the packing tape, tape head splitting or other abnormal conditions, and the small in-place detection swing rod 41 on the binding machine core 10 cannot be triggered, the tape feeding and withdrawing motor 617 is controlled to rotate reversely for one unit of tape withdrawing time through the PIC program to execute the tape withdrawing action, the tape feeding and withdrawing main wheel 609 and the tape feeding and withdrawing pressing wheel 610 are mutually abutted to press and drive the packing tape to convey in the reverse direction, the packing tape is withdrawn into the arc-shaped tape channel, and the phenomenon that the packing tape falls out from the tape inlet 614 of the machine core cannot occur due to the fact that the packing tape is limited by the arc.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
