A cutting device 30 is located below the movable plate 31. A conveyor belt is formed between the cutting device 30 and the movable plate 31 for the packing strap to pass through (the direction of the arrow shown in the figure is the direction of the packing strap forward on the conveyor belt). The packing strap enters from the conveyor belt through the lever device 20 and packages the object to be packaged located above the movable plate 31.

[0048] <Lever Mechanism>

[0050] like Figure 3As shown, the dialing rod device 20 comprises a dialing rod 21 for dialing the packing belt and leading the packing belt into the belt channel, a swing arm mechanism movably installed at one end of the dialing rod 21, and a driving mechanism for driving the swing arm mechanism and the dialing rod to move. Specifically, the swing arm mechanism has a swing arm 22, a movable shaft 23, and a connecting head 24, one end of the swing arm 22 is integrally welded with the movable shaft 23, and the other end is rotatably installed at one end of the dialing rod 21 through the connecting head 24, and the other end of the dialing rod 21 has a dialing head 211 for dialing the packing belt. The driving mechanism comprises a swing assembly, a dialing assembly, and a lifting assembly, so as to Figure 1 The swing assembly can drive the swing arm 22 and the dialing rod 21 to swing in the X direction, the dialing assembly can drive the dialing rod 21 to swing in the Y direction, and the lifting assembly can drive the movable shaft 23 to move in the Z direction, and the swing assembly, the dialing assembly, and the lifting assembly are all driven to work by the same driving main shaft 25. The driving main shaft 25 can be controlled to rotate by a manual wheel or a motor.

[0051] Figure 4 is the front angle structure diagram of the dialing assembly of the present application.

[0052] Figure 5 is the front angle structure diagram of the dialing assembly of the present application.

[0053] As shown in Figure 4 , the dialing assembly has a dialing wheel 26, a rotating rod 27, and a pull rod 28, the dialing wheel 26 can be driven to rotate by the driving main shaft 25, the rotating rod 27 can be driven to rotate by the dialing wheel 26, one end of the pull rod 28 is connected with the rotating rod 27, and the other end is connected with the dialing rod 21, the dialing wheel 26 is driven to rotate by the driving main shaft 25, thereby driving the rotating rod 27 to swing, and the rotating rod 27 drives the dialing rod 21 to swing through the pull rod 28.

[0054] As shown in Figure 5 , a vertical installation plate 11 is arranged in the middle of the rack 10, the driving main shaft 25 and the dialing assembly are respectively located on the two sides of the installation plate 11, the driving main shaft 25 is connected with the dialing wheel 26 through a gear assembly, the gear assembly comprises a driving bevel gear 251 fixed on the driving main shaft 25, a driven bevel gear 252 meshing with the driving bevel gear 251, and a wheel shaft 253, one end of the wheel shaft 253 is combined with the driven bevel gear 252, and the other end is combined with the dialing wheel 26. A through hole 111 is formed in the installation plate 11, the wheel shaft 253 is installed at the through hole 111 through an axle seat 255, a bearing 256 is further arranged between the wheel shaft 253 and the axle seat 255, the driven bevel gear 252 is fixed on the wheel shaft 253 extending out of the through hole 111, and the other side of the wheel shaft 253 is combined with the dialing wheel 26, so that the dialing wheel 26 can be driven to rotate by the driving main shaft 25. As Figure 8As shown, the driven helical gear 252 and the axle 253 are fixed by a key connection. In reality, bolts and washers can also be used for fixing. In comparison, the key connection can make the connection tighter, while the bolt connection is prone to loosening after long-term use.

[0055] Combination Figure 4 One end of the rotating rod 27 is rotatably mounted on the mounting plate 11 via a rotating shaft 271, and the other end is equipped with a pull rod 28. A tension spring is provided between the end of the rotating rod 27 near the mounting pull rod 28 and the mounting plate 11. Figure 4 Not shown in the image, please refer to the following: Figure 22 A tension spring 91 is used to assist the rotating rod 27 in continuously abutting against the outer contour of the actuating wheel 26. A roller 52, which can roll relative to the outer edge of the actuating wheel 26, is provided in the middle of the rotating rod 27. The actuating wheel 26 is a cam, with spaced recesses 261 and protrusions 262 on its outer edge. When the roller 52 rolls on the recesses 261, the lever 21 swings away from the rotating rod 27; when the roller 52 rolls on the protrusions 262, the lever swings closer to the rotating rod. In this embodiment, the roller 52 is a bearing, with its middle portion mounted on the rotating rod 27 via a mounting shaft, and its outer ring able to roll relative to the outer edge of the actuating wheel 26.

[0056] like Figure 4 As shown, the pull rod 28 can be configured as an adjusting rod. Both ends of the pull rod 28 have screws 281. Each screw 281 has a threaded connector 282 and a locking nut 283. One end of the threaded connector 282 is threadedly connected to the screw 281, and the other end is connected to the rotating rod 27 and the lever 21. By adjusting the connection distance between the threaded connector 282 and the screw 281, and locking it with the locking nut 283, the installation distance between the rotating rod 27 and the lever 21 is adjusted, thereby adjusting the rotation (leveraging) amplitude of the lever 21 to adjust the final stopping position of the lever 21 according to actual needs. Alternatively, the lever head 211 at the upper end of the lever 21 can also be configured as follows... Figure 4 As shown in the adjustable configuration, the dial head 211 is mounted on the upper end of the lever 21 via an adjusting bolt 212. Specifically, a slotted hole is provided at the upper end of the lever 21, through which the adjusting bolt 212 passes and is fixed to the dial head 211. When the height of the dial head 211 needs to be adjusted, the fixed position of the adjusting bolt within the slotted hole can be adjusted.

[0057] Figure 6 This is an installation structure diagram of the swing assembly of the present invention.

[0058] like Figure 6As shown, the swing assembly has a swing wheel 29 and a swing roller 51, the swing wheel 29 is coaxially arranged with the driving wheel 26, and the swing wheel 29 is directly installed on the driving wheel 26, both of which are driven by the driving shaft 25 to rotate, the swing roller 51 is installed on the swing arm 22, and the swing roller 51 can roll along the end face of the swing wheel 29. The swing arm 22 is provided with a mounting seat 221, and the swing roller 51 is installed on the mounting seat 221 through a pin shaft, when the swing roller 51 rolls along the end face of the swing wheel 29, the swing roller 51 also rotates around the pin shaft.

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

[0060] Figure 8 is the sectional view of the swing wheel mounting structure of the application.

[0061] As Figure 7 and Figure 8 shown, the swing wheel 29 contains an inner end face 291 and an outer end face 292, the inner end face 291 is arranged towards the driving wheel 26, and the outer end face 292 is arranged away from the driving wheel 26, the outer end face 292 outwardly protrudes 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. The driving wheel 26 is sleeved on the wheel shaft 253, and the middle part is formed with a boss 263, the swing wheel 29 is provided with a through hole 297 in the middle part, the through hole 297 is sleeved on the outer periphery of the boss 263, and then the swing wheel 29 is fixed on the driving wheel 26 through screws or bolts.

[0062] The swing wheel 29 rotates in the counterclockwise direction under the driving of the driving shaft 25, at this time, 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, in the rolling process of the horizontal section of the first channel 295 or the second channel 296, the pull rod 28 can move the push rod 21 away from the rotating rod 27, at the connection between the first channel 295 and the first protrusion 293, the second protrusion 294 or the connection between the second channel 296 and the first protrusion 293, the second protrusion 294, the swing roller 51 is in a climbing or downhill position, at this stage, the swing arm 22 can move the push rod 21 away from or close to the mounting plate 11, to realize the swing of the push rod 21 in the X-axis direction. At the same time, the swing arm 22 and the rack 10 are also provided with a tension spring 222 (as Figure 23 shown), to facilitate the reset of the swing arm 22.

[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.

[0065] Figure 9 This is an installation structure diagram of the lifting component of the present invention.

[0066] Figure 10 This is a perspective view of the lifting component of the present invention.

[0067] like Figure 9 and Figure 10 As shown, the lifting assembly includes a lifting component 61, a lifting roller 62, a lifting bracket 63, a guide post 64, and a first elastic element 65. The lifting component 61 is connected to the movable shaft 23. The lifting roller 62 is mounted on the lifting bracket 63 and acts on the lifting component 61 to drive the lifting component 61 to move up and down. The lifting bracket 63 is linked to the drive spindle 25, and under the drive of the drive spindle 25, the lifting bracket 63 moves up and down. The guide post 64 is fixedly mounted on the mounting plate 11, and the first elastic element 65 is a spring, sleeved on the upper end of the outer periphery of the guide post 64. In this embodiment, the movable shaft 23 is a hollow cylinder, sleeved on the outer periphery of the guide post 64, and one end of the first elastic element 65 abuts against the movable shaft 23 to help the movable shaft 23 return to its original position.

[0068] Figure 11 This is a front view of the lifting roller mounting structure of the present invention.

[0069] The lifting roller 62 has a first end surface 621, a second end surface 622 and a peripheral surface 623, the first end surface 621 is combined with the lifting support 63, the second end surface 622 is towards the movable shaft and a gap exists between the second end surface 622 and the movable shaft, the peripheral surface 623 is in contact with the lower end surface of the lifting component 61, the lifting roller 62 is lifted by the lifting support 63, the lifting component 61 is lifted in the lifting process, the lifting component 61 is moved upwards with the movable shaft 23, so that the rocker arm 22 is moved upwards with the push rod 21.

[0070] Figure 12 Fig. 3 is a connection structure diagram of the lifting assembly and the driving main shaft of the present application.

[0071] As shown in Figure 12 Fig. 2, the driving main shaft 25 is provided with a first cam 254, the lifting support 63 has a movable plate 631, a first sliding block assembly 632 and a support plate 633, the support plate 633 is L-shaped, one end of the support plate 633 is provided with a first roller 53 which cooperates with the first cam 254, the other end of the support plate 633 is fixed on the sliding block of the first sliding block assembly 632, the sliding rail of the first sliding block assembly 632 is vertically installed on the mounting plate 11. One end of the movable plate 631 is installed on the sliding block of the first sliding block assembly 632 and can move up and down on the sliding rail along with the sliding block; the other end of the movable plate 631 is used to install the lifting roller 62. The lifting roller 62 is provided with at least two and is uniformly arranged on the lower end surface of the lifting component 61, so that the lifting component 61 is uniformly stressed in the process of being lifted by the lifting roller 62. In the embodiment, the lifting component 61 is separately provided with the movable shaft 23, the lifting component 61 is in the shape of a hollow circular ring, is sleeved on the upper end of the outer periphery of the movable shaft 23 and is fixed with the movable shaft 23 from the peripheral surface by a fixing piece, the movable shaft 23 is also provided with a circlip at the upper end surface of the lifting component 61 to position the movable shaft 23 in the axial direction. Since the lifting component 61 is relatively fixed with the movable shaft 23, when the movable shaft 23 rotates (the rocker arm 22 is swung by the swinging assembly), the lifting component 61 also rotates, so that the force in the plane is generated between the lower end surface of the lifting component 61 and the peripheral surface of the lifting roller 62. In order to avoid abrasion, the cylindrical lifting roller 62 (the peripheral surface of the lifting roller 62 is used as the contact surface) is used to drive the lifting component 61, so that each component can be better protected.

[0094] The packaging process of the packaging machine is as follows:

[0095] Fig. 21 is a schematic diagram of the state of the packaging tape of the packaging machine in the packaging process.

[0096] As Figure 21a shown, the object 81 to be packaged is waiting to be sent to the packaging platform 82 (the packaging platform 82 is located in the upper region of the moving plate 31), and in the initial position, the leading end of the packaging tape 83 is clamped between the positioning knife 32 and the top block 33, and the lever 21 is located near the packaging tape 83. Start the machine, the object 81 starts to move in the direction of the arrow in the figure, until its one side surface (the left side in the figure) moves beyond the clamping block 35, and then the lever 21 starts to move the packaging tape for the first time: the lever 21 moves the packaging tape 83 towards the direction of the movement of the object 81, and since the lever 21 is in a rotating state, it will move the packaging tape 83 to the lower side of the moving plate 31, and during this period, the moving plate 31 will move out to the upper side of the packaging tape along the X-axis direction, and during this movement, the leading end of the packaging tape is always clamped.

[0097] As Figure 21bAs shown, after the wrapping tape 83 is wound around part of the object 81, the lever 21 is swung to the first position (behind the clamping block 35, the rear side here refers to the advancing direction of the wrapping tape, the initial position is forward and the position after the lever is swung is rear), the clamping block 35 moves upward along the Z axis, gradually clamping the first layer of wrapping tape 831 between the clamping block 35 and the moving plate 31. When the wrapping tape is clamped by the clamping block 35 and the moving plate 31, the lever 21 begins to retract, i.e. moves out of the wrapping tape 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 retreats along the X axis, so that the leading end of the wrapping tape 83 is released.

[0098] As Figure 21c shown, after the leading end of the wrapping tape 83 is released, the pressing plate 381 rotates to flatten and press the leading end of the wrapping tape 83 between the pressing plate 381 and the moving plate 31. Then, the tape guiding device 40 pushes the wrapping tape to the lower side of the moving plate 31 to wrap the object, and then the lever 21 is used to secondly move the wrapping tape 83, so that the subsequent wrapping tape 83 is tightly attached to the outer side of the object and enters from below the first layer of wrapping tape 831, thereby forming the second layer of wrapping tape 832.

[0099] As Figure 21d shown, during the movement of the lever 21, the second layer of wrapping tape 832 is bent on both sides of the lever head 211, and at the same time, the pressing plate 381 retreats away from the first layer of wrapping tape 831, and the positioning knife 32 and the top block 33 begin to move. During this process, the ironing head 36 also extends below the first layer of wrapping tape 831. When the lever 21 moves to the position between the cutter 34 and the ironing head 36 (i.e. to 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 wrapping tape, and then the cutter 34 moves upward to cut the second layer of wrapping tape 832 along the top block 33.

[0100] As Figure 21e shown, after the second layer of wrapping tape 832 is cut, the lever 21 continues to swing towards the direction of the rotating rod to flatten and stretch the second layer of wrapping tape 832 below the lever head 211 along the bottom of the ironing head, and at the same time, the pressing block 37 gradually moves upward to gradually press the second layer of wrapping tape 832 against the bottom of the ironing head. When the lever 21 is separated from the wrapping tape, the ironing head 36 is located between the first layer of wrapping tape 831 and the second layer of wrapping tape 832, and then the two layers of wrapping tape are heat-fused.

[0101] As Figure 21fAs shown, after the hot melting, the iron 36 retreats to leave the packing tape, and the block 37 moves up to press the two layers of packing tape together. After the packing tape is pressed together, the moving plate 31, the block 37 and the clamp 35 are gradually withdrawn to the original position. The packing tape under the moving plate 31 will automatically adhere to the bottom of the object after the moving plate 31 is withdrawn, thereby completing the packing of the object.

[0103] Figure 22 is a structural schematic diagram of the core system of the packing machine according to the present application.

[0104] The present embodiment is basically the same as the above-mentioned embodiment 1, and the difference is that, as shown in 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 of the pull rod 28, is extended to form a connecting block 272, and a connecting column is arranged on the connecting block 272. One end of the pull spring 91 is hooked on the connecting column, and the other end is hooked on the connecting column installed on the mounting plate 11.
