[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a PET-PP tape receiving and sending mechanism for an automatic baler, comprising an installation frame 1, wherein the installation frame 1 is provided with a tape feeding port 11 and a tape outlet 12, wherein the PET-PP tape enters from the tape feeding port 11 and passes through the tape outlet 12, wherein the receiving and sending mechanism further comprises a tightening device 2, a pressing device 3 and a connecting rod mechanism 4, wherein the tightening device 2, the pressing device 3 and the connecting rod mechanism 4 cooperate with each other to receive and send the PET-PP tape, wherein sending refers to sending the PET-PP tape from the mechanism to the baling mechanism, and receiving refers to pulling the PET-PP tape back from the baling mechanism, wherein the PET-PP tape is bundled on the goods through the action of sending and receiving the tape in cooperation with the baling mechanism.

[0024] In this embodiment, the mounting frame 1 includes a bottom plate 13 and four side plates 14. The four side plates 14 are respectively installed vertically on the four sides of the bottom plate 13. The side plates 14 are connected together by connecting pieces 15. There is also a cover plate (not shown in the figure) on the side opposite to the bottom plate 13, so that the entire mounting frame 1 constitutes a closed cubic space to better protect the internal components. In addition, the side plates 14 at the bottom are two grooved steels 16 installed opposite to each other. Connecting plates 17 are provided on both sides of the top of the mounting frame 1. Bolts are provided on the connecting plates 17, so that the utility model can be better installed on the assembly line where the packaging equipment is located. Ventilation holes 18 are provided on the mounting frame 1 to cool the interior.

[0025] In this embodiment, the tightening device 2 includes a tightening servo motor 21, a tightening wheel 22 and a driven wheel 23. The tightening wheel 22 is arranged at the shaft end of the tightening servo motor 21, and the tightening wheel 22 is connected to the driven wheel 23 through a synchronous belt 24. Specifically, the tightening servo motor 21 is installed on one side of the bottom plate 13, the driving shaft of the tightening servo motor 21 passes through the bottom plate 13, and the tightening wheel 22 and the driven wheel are both installed on the other side of the bottom plate 13 away from the main body of the tightening servo motor 21.

[0026] In a specific embodiment of the present embodiment, an adjustment component is provided on the synchronous belt 24, and the adjustment component includes an adjustment frame 25, a waist hole 26 at one end of the adjustment frame 25, and a roller 27 is provided between the two waist holes 26. The roller 27 is set in the waist hole 26 by a screw. The adjustment component can adjust the tightness of the synchronous belt 24.

[0027] In this embodiment, the clamping device 3 includes a clamping servo motor 31, a cam 32, a swing rod 33 and a pressure block 34. The cam 32 is arranged at the shaft end of the clamping servo motor 31, and the swing rod 33 is arranged between the cam 32 and the pressure block 34. The cam 32 drives the swing rod 33 to swing and drives the pressure block 34 to tighten / loosen the tightening wheel 22. Specifically, the tightening servo motor 31 and the clamping servo motor 21 are both installed on the same side of the mounting frame 1, which can save the installation space of the utility model. The swing rod 33 is rotatably connected to the base plate 13 through a connecting column, and the pressing block 24 is slidably arranged on the base plate 13. A first spring 35 is arranged on the pressing block 24, and one end of the first spring 35 is hung on the side plate 14 located on the other side of the swing rod 33. The first spring 35 drives the pressing block 24 to move in the direction of the swing rod 33, and the swing rod 33 drives the pressing block 24 to move in the direction of the tightening wheel 22. The swing frequency of the swing rod 33 is determined by the cam 32. When the swing rod 33 moves to the left, a gap is generated between the pressing block 24 and the tightening wheel 22. At this time, the PET-PP belt passes through the gap under the action of the connecting rod mechanism 4 and moves in the direction of the packaging mechanism. When the swing rod 33 moves to the left, the pressing block 24 is pressed against the tightening wheel 22, and the PET-PP belt stops moving. At this time, if it is necessary to wind up the belt, the tightening servo motor 21 rotates in the opposite direction, so that the PET-PP belt can move from the packaging mechanism to the direction of the utility model.

[0028] In this embodiment, in order to make the connecting rod mechanism 4 include the connecting rod 41, the pressing wheel 42 and the pressing wheel mounting frame 43, the two ends of the connecting rod 41 are respectively movably connected to the pressing wheel 42 and the pressure block 24, and the pressing wheel 42 is mounted on one end of the pressing wheel mounting frame 43. The other end of the pressing wheel mounting frame 43 is rotatably mounted on the bottom plate 13, and the upper side of the pressing wheel mounting frame 43 is further provided with a second spring 44, which is used to press the pressing wheel 42 downward, thereby making the pressing wheel 42 close to the driven wheel 23, and the PET-PP belt is tangent to the surface of the pressing wheel 42 and the driven wheel 23, and the driven wheel 23 drives the PET-PP belt to move toward the packaging mechanism. When the pressing block 24 moves to the left, the connecting rod 41 drives the pressing wheel 42 to move downward, so that the pressing wheel 42 is pressed against the driven wheel 23, and at this time a gap is generated between the pressing block 24 and the tensioning wheel 22, so the movement direction of the PET-PP tape is from the feeding port 11 to the tape outlet 12; when the pressing block 24 moves to the right, the gap between the pressing block 24 and the tensioning wheel 22 disappears, the connecting rod 41 lifts the pressing wheel 42 upward, and the tape feeding action stops. The length of the connecting rod 41 is adjustable, and the tightness between the pressing wheel 42 and the driven wheel 23 can be adjusted.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
