[0059] Figure 7 It is a structure diagram of the swing wheel of the application.

[0060] Figure 8 It is a sectional view of the swing wheel installation structure of the application.

[0061] As shown Figure 7 and Figure 8As shown, the swing wheel 29 comprises an inner end surface 291 and an outer end surface 292, the inner end surface 291 is arranged towards the driving wheel 26, and the outer end surface 292 is arranged away from the driving wheel 26, the outer end surface 292 is outwardly protruded to form a first protrusion 293 and a second protrusion 294, a first channel 295 and a second channel 296 are connected between the first protrusion 293 and the second protrusion 294, and the swing roller 51 can relatively roll along the first channel 295, the top surface of the first protrusion 293, the second channel 296 and the top surface of the second protrusion 294.

At the same time, the swing arm 22 and the rack 10 are further provided with a tension spring 222 (as shown), which is convenient for the reset of the swing arm 22. Figure 23

[0063] ​Furthermore, since the oscillating roller 51 rolls relative to the outer end face (first channel, second channel, outer surface of the first protrusion, outer surface of the second protrusion) of the oscillating wheel 29, the height of the first and second protrusions protruding relative to the main body of the oscillating wheel 29 directly affects the swing amplitude of the lever 21 in the front-back direction. In this embodiment, the first and second protrusions are set on the outer end face of the oscillating wheel 29 (i.e., the side away from the mounting plate 11), so that the protrusion height of the first and second protrusions can have a larger adjustment range to adapt to different sizes of packing straps. For example, if the packing strap of the packing machine 100 is wider, the corresponding lever swing amplitude in the X-axis direction will be larger, and a oscillating wheel 29 with a higher protrusion height should be adapted. Since the first and second protrusions are located on the outer end face of the oscillating wheel 29, the protrusion height of the protrusions and the swing of the swing arm 22 are not restricted. The oscillating wheel 29 with protrusions of corresponding heights can be selected and replaced according to actual needs. In addition, by placing the protrusion on the outside of the swing wheel, the swing arm 22 can be located on the outside of the entire toggle assembly, and the swing of the swing arm in the X-axis will not be interfered with by the toggle assembly, which is suitable for wide-band applications.

[0064] In this embodiment, the swing wheel 29 and the actuating wheel 26 are mounted together and driven to rotate together by the drive spindle 25, so that the lever 21 can swing horizontally relative to the mounting plate 11 and move back and forth relative to the mounting plate 11.

[0093] The packaging process of the packaging machine is as follows:

[0094] Figure 21 is a schematic diagram of the state of the packaging tape of the packaging machine in the packaging process.

[0095] As shown in the figure, Figure 21aAs shown, the object 81 to be packaged is waiting to be sent to the packaging platform 82 (located above the moving plate 31). In the initial position, the first end of the packaging strap 83 is clamped between the positioning knife 32 and the top block 33, and the lever 21 is located near the packaging strap 83. The machine is started, and the object 81 begins to move in the direction of the arrow in the figure until one of its surfaces (the left side in the figure) moves past the clamping block 35. Then, the lever 21 begins to move the packaging strap for the first time: the lever 21 moves the packaging strap 83 in the direction of the object 81's movement. Since the lever 21 is rotating, it moves the packaging strap 83 below the moving plate 31. During this process, the moving plate 31 moves out along the X-axis to above the packaging strap. During this movement, the first end of the packaging strap remains clamped.

[0096] like Figure 21b As shown, after the packing strap 83 wraps around part of the object 81, the lever 21 swings to the first position (located behind the clamping block 35; "behind" here refers to the direction along which the packing strap moves forward; the initial position was forward, and the position after the lever is backward). The clamping block 35 moves upward along the Z-axis, gradually clamping the first layer of packing strap 831 between the clamping block 35 and the moving plate 31. After the packing strap is clamped by the clamping block 35 and the moving plate 31, the lever 21 begins to retract, that is, it moves out of the packing strap and returns to the initial position. At the same time, during the retraction of the lever 21, the top block 33 moves downward along the Z-axis, and the positioning knife 32 retracts along the X-axis, so that the first end of the packing strap 83 is released.

[0097] like Figure 21c After the first end of the strapping 83 is released, the pressure plate 381 rotates to flatten and press the first end of the strapping 83 between the pressure plate 381 and the moving plate 31. Next, the guide device 40 pushes the strapping below the moving plate 31 to wrap the object. Then, the lever 21 moves the strapping 83 a second time, so that the subsequent strapping 83 is close to the outside of the object and enters below the first layer of strapping 831, thus forming the second layer of strapping 832.

[0098] like Figure 21d As shown, during the process of the lever 21 moving the packing strap, the second layer of packing strap 832 bends at the lever 21 and is located on the upper and lower sides of the lever head 211. At the same time, the pressure plate 381 retracts away from the first layer of packing strap 831, and the positioning knife 32 and the top block 33 begin to move. During this process, the heating head 36 also extends under the first layer of packing strap 831. When the lever 21 moves to the position between the cutter 34 and the heating head 36 (i.e., in the second position), it will stay for a period of time. The positioning knife 32 and the top block 33 clamp the end of the second layer of packing strap, and then the cutter 34 moves up to cut the second layer of packing strap 832 along the top block 33.

[0099] like Figure 21eAs shown, after the second layer of packing belt 832 is cut off, the lever 21 will continue to swing towards the direction of the rotating rod, so as to stretch the second layer of packing belt 832 below the lever head 211 along the bottom of the ironing head, and at the same time, the pressing block 37 is gradually moved upwards, and the second layer of packing belt 832 is gradually pressed on the bottom of the ironing head. When the lever 21 is separated from the packing belt, the ironing head 36 is located between the first layer of packing belt 831 and the second layer of packing belt 832, and then the two layers of packing belt are hot melted.

[0100] As shown in the figure, Figure 21f After hot melting, the ironing head 36 retreats and leaves the packing belt, and the pressing block 37 moves upwards to press the two layers of packing belt together. After the packing belt is pressed together, the moving plate 31, the pressing block 37 and the clamping block 35 are gradually withdrawn and returned to the original position. The packing belt below the moving plate 31 is automatically attached to the bottom of the object after the moving plate 31 is withdrawn, thereby completing the packing of the object.

[0101] <Embodiment 2>

[0102] Figure 22 is a structural schematic diagram of the core system of the packing machine according to Embodiment 2 of the present application.

[0103] This embodiment is basically the same as Embodiment 1 described above, and the difference is that, as shown in the figure, Figure 22 The structure of the rotating rod 27 is slightly different. The upper end of the rotating rod 27, i.e. the end close to the installation rod 28, extends to form a connecting protrusion 272, and a connecting column is arranged on the connecting protrusion 272. One end of the tension spring 91 is hooked on the connecting column, and the other end is hooked on a connecting column arranged on the mounting plate 11.

[0104] Effects of the above embodiments:

[0105] In the above embodiment, the swing wheel 29 on the swing assembly protrudes on the outer side (i.e. the side away from the mounting plate 11) to form a first protrusion and a second protrusion, and the swing roller 51 also rolls along the outer end surface of the swing wheel 29. The height of the first protrusion and the second protrusion protruding from the main body of the swing wheel 29 directly affects the swing amplitude of the lever 21 in the front-back direction. Therefore, by arranging the first protrusion and the second protrusion on the outer end surface of the swing wheel 29, the protrusion height of the first protrusion and the second protrusion has a larger adjustment range, so as to adapt to packing belts of different sizes and have a wider application range.

[0106] Meanwhile, the driving mechanism is also provided with a lifting assembly, and the lifting assembly is also driven by the driving main shaft 25 to work, so that the lever 21 can swing in the horizontal direction, the vertical direction and the front-back direction at the same time, so as to meet the requirements of packing belt guiding and swinging in various angles.

[0107] Further, the lifting roller 62 is used to drive the lifting component 61 to move in the lifting assembly, which not only can play the role of lifting driving, but also can form the rolling friction when the lifting component 61 rotates, reduce the abrasion, and better protect each component.

[0108] The above examples are only used for illustrating the specific embodiments of the present application, and the present application is not limited to the description range of the above examples. For example, in the above examples, the lifting component 61 is separately arranged with the movable shaft 23, and in the actual situation, the lifting component 61 can be integrally formed on the movable shaft 23.
