Description

Technical Field

[0001] The present invention belongs to the technical field of baling machines, and in particular relates to a core system for a baling machine and a baling machine. Background Art

[0002] A baler, also known as a strapping machine, is used to wrap strapping tape around an object to be packaged, then cut the strapping tape with a cutter and fuse the ends of the tape together to complete the packaging. Existing balers, such as the one proposed by the applicant in the prior invention patent CN112278965B, although this structure can package items, the strapping tape must first pass through the entire tape guide frame when packaging, and then be loosened by the tape guide frame and tightened by the tightening mechanism. Finally, the cutter device first welds the strapping tape and then cuts it. The entire structure is more complicated due to the arrangement of the tape guide frame, and the entire device is larger. In addition, the tape guide frame has certain restrictions on the size of the item. Once the width or height of the item exceeds the size of the tape guide frame, it will become unsuitable. Therefore, this type of strapping machine (baler) has certain limitations. Summary of the Invention

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following is a detailed description of the baler movement system and baler of the present invention in conjunction with the embodiments and drawings.

[0042] <Example 1>

[0043] Figure 1 It is a structural diagram of the baler core system from a forward angle according to the present invention.

[0044] Figure 2 It is a rear-angle structural diagram of the baler core system of the present invention.

[0045] This embodiment provides a baler, more specifically, a frameless baler. The baler comprises a body, a core system 100 mounted on the body, a material belt system, and a packaged object conveying system. The material belt system is used to store and transport the baling belt, the packaged object conveying system is used to transport the objects to be packaged, and the core system 100 is used to wrap the baling belt around the objects to be packaged for packaging.

[0046] like Figure 1 and Figure 2As shown, the movement system 100 includes a frame 10, a lever device 20, a tool device 30, a belt guide device 40 and a driving device, wherein the lever device 20 and the tool device 30 are installed on the frame 10, and the lever device 20 is used to move the strapping tape into the tool device 30; the tool device 30 is used to compress the strapping tape and assist the lever device to cut and fuse the object after it is wrapped; the belt guide device 40 is located on one side of the frame 10, and has rollers and hooks and other auxiliary components for guiding the strapping tape (existing technology, not shown in the figure) and a guide member 41 for guiding the strapping tape into the tool device 30; the driving device has a driving spindle 25 that can simultaneously drive the tool device 30 and the lever device 20 to work, and a power source (such as a manual wheel or a motor and a reducer) that drives the driving spindle 25 to rotate. The tool device 30 and the lever device 20 are simultaneously driven by the same power source and the driving spindle 25. The entire driving structure is simple, highly synchronous, and easy to control.

[0047] like Figure 1 As shown, a movable plate 31 is movably provided on the frame 10, and the upper portion of the movable plate 31 is used to place objects to be packaged. The tool device 30 is provided below the movable plate 31, and a belt path for the strapping tape to pass through is formed between the tool device 30 and the movable plate 31 (the direction of the arrow in the figure is the direction in which the strapping tape advances on the belt path). The strapping tape enters the belt path through the shifting lever device 20 to package the objects to be packaged located above the movable plate 31.

[0048] <Lever device>

[0049] Figure 3 It is a structural diagram of the lever device of the present invention installed on the frame.

[0050] like Figure 3 As shown, the lever device 20 includes a lever 21, a swing arm mechanism, and a driving mechanism. The lever 21 is used to move the strapping tape and bring the strapping tape into the belt path. The swing arm mechanism is movably mounted on one end of the lever 21. The driving mechanism is used to drive the swing arm mechanism and the lever to move. Specifically, the swing arm mechanism includes a swing arm 22, a movable shaft 23, and a connector 24. One end of the swing arm 22 is welded to the movable shaft 23, and the other end is rotatably mounted on one end of the lever 21 through the connector 24. The other end of the lever 21 has a dial head 211 for moving the strapping tape. The driving mechanism includes a swing assembly, a toggle assembly, and a lifting assembly. Figure 1 Based on the coordinate axis in , the swing assembly can drive the swing arm 22 and the toggle rod 21 to swing in the X direction, the toggle assembly can drive the toggle rod 21 to swing in the Y direction, and the lifting assembly can drive the movable shaft 23 to move in the Z direction. The swing assembly, the toggle assembly and the lifting assembly are all driven by the same driving spindle 25.

[0051] Figure 4 It is a structural diagram of the toggle assembly of the present invention from a forward angle.

[0052] Figure 5 It is a structural diagram of the toggle assembly of the present invention from a top-down angle.

[0053] like Figure 4 As shown, the toggle assembly includes a toggle wheel 26, a rotating rod 27 and a pull rod 28. The toggle wheel 26 can be rotated by the driving main shaft 25, and the rotating rod 27 can be rotated by the driving main shaft 25. One end of the pull rod 28 is connected to the rotating rod 27, and the other end is connected to the toggle rod 21. The toggle wheel 26 is rotated by the driving main shaft 25, thereby driving the rotating rod 27 to swing, and the rotating rod 27 then drives the toggle rod 21 to swing through the pull rod 28.

[0054] like Figure 5 As shown, a vertical mounting plate 11 is provided in the middle of the frame 10. The driving spindle 25 and the toggle assembly are respectively located on both sides of the mounting plate 11. The driving spindle 25 is connected to the toggle wheel 26 through a gear assembly. The gear assembly includes a driving bevel gear 251 fixed to the driving spindle 25, a driven bevel gear 252 meshing with the driving bevel gear 251, and a wheel axle 253. One end of the wheel axle 253 is coupled to the driven bevel gear 252, and the other end is coupled to the toggle wheel 26. A through hole 111 is provided on the mounting plate 11. The wheel axle 253 is mounted on the through hole 111 through an axle seat 255. A bearing 256 is further provided between the wheel axle 253 and the axle seat 255. The driven bevel gear 252 is fixed to the wheel axle 253 extending from one side of the through hole 111. The other side of the wheel axle 253 is coupled to the toggle wheel 26, so that the toggle wheel 26 can rotate under the drive of the driving spindle 25. As shown Figure 8 As shown, the driven helical gear 252 and the axle 253 are fixed by a key connection. In reality, they can also be fixed by bolts and gaskets. In comparison, the key connection can make the connection tighter, while the bolt connection is prone to loosening after long-term use.

[0055] Combine Figure 4 One end of the rotating rod 27 is rotatably mounted on the mounting plate 11 through the rotating shaft 271, and the other end is mounted with a pull rod 28, and a tension spring is provided between the end of the rotating rod 27 close to the mounting pull rod 28 and the mounting plate 11 ( Figure 4 Not shown, please refer to Figure 22A tension spring 91 is used to help the rotating rod 27 maintain contact with the outer contour of the toggle wheel 26. A roller 52 is positioned in the middle of the rotating rod 27, capable of rolling relative to the outer edge of the toggle wheel 26. The toggle wheel 26 is a cam, with recesses 261 and protrusions 262 arranged at intervals along its outer edge. When the roller 52 rolls on the recesses 261, the toggle rod 21 swings away from the rotating rod 27; when the roller 52 rolls on the protrusions 262, the toggle rod swings toward the rotating rod. In this embodiment, the roller 52 is a bearing, with its center mounted on the rotating rod 27 via a mounting shaft, and its outer ring capable of rolling relative to the outer edge of the toggle wheel 26.

[0056] like Figure 4 As shown, the pull rod 28 can be set as an adjustment rod, with screws 281 at both ends of the pull rod 28, and threaded connectors 282 and locking nuts 283 are provided on the screws 281 on both sides. 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 deflector 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 deflector 21 is achieved, thereby adjusting the rotation (deflection) amplitude of the deflector 21, so as to adjust the final stop position of the deflector 21 according to actual needs. In addition, the dial head 211 at the upper end of the deflector 21 can also be set as follows Figure 4 In the adjustable manner shown, the dial head 211 is mounted on the upper end of the dial rod 21 via an adjusting bolt 212. Specifically, a strip-shaped hole is provided at the upper end of the dial rod 21, and the adjusting bolt 212 passes through the strip-shaped hole 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 in the strip-shaped hole can be adjusted.

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

[0058] like Figure 6 As shown, the swing assembly includes a swing wheel 29 and a swing roller 51. The swing wheel 29 is coaxially arranged with the toggle wheel 26 and is directly mounted on the toggle wheel 26. Both are driven to rotate by the drive spindle 25. The swing roller 51 is mounted on the swing arm 22 and can roll along the end surface of the swing wheel 29. The swing arm 22 is provided with a mounting seat 221. The swing roller 51 is mounted on the mounting seat 221 via a pin. When the swing roller 51 rolls along the end surface of the swing wheel 29, the swing roller 51 also rotates about the pin.

[0059] Figure 7 It is a structural diagram of the swing wheel of the present invention.

[0060] Figure 8 It is a cross-sectional view of the swing wheel mounting structure of the present invention.

[0061] like Figure 7 and Figure 8 As shown, the swing wheel 29 includes an inner end surface 291 and an outer end surface 292. The inner end surface 291 faces the toggle wheel 26, while the outer end surface 292 faces away from the toggle wheel 26. A first protrusion 293 and a second protrusion 294 are formed outwardly on the outer end surface 292. A first channel 295 and a second channel 296 are formed between the first protrusion 293 and the second protrusion 294. The swing roller 51 can roll relative to each other 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 toggle wheel 26 is mounted on the wheel shaft 253, and a boss 263 is formed in the middle thereof. A through hole 297 is formed in the middle of the swing wheel 29, and the through hole 297 is mounted on the outer periphery of the boss 263. The swing wheel 29 is then fixed to the toggle wheel 26 by screws or bolts.

[0062] Driven by the driving main shaft 25, the swing wheel 29 rotates in the counterclockwise direction. At this time, the swing roller 51 can roll relative to 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. During the horizontal rolling process of the first channel 295 or the second channel 296, the pull rod 28 can move the shift rod 21 in the direction 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 descending position. At this stage, the swing arm 22 can move the shift rod 21 in the direction away from or close to the mounting plate 11, so as to realize the swing of the shift rod 21 in the X-axis direction. At the same time, a tension spring 222 (such as Figure 23 As shown), it is convenient for the swing arm 22 to be reset.

[0063] Furthermore, since the swing roller 51 rolls relative to the outer end surface of the swing wheel 29 (the first channel, the second channel, the outer surface of the first protrusion, and the outer surface of the second protrusion), the height of the first and second protrusions relative to the main body of the swing wheel 29 directly affects the swing amplitude of the lever 21 in the forward and backward directions. In this embodiment, the first and second protrusions are positioned on the outer end surface of the swing wheel 29 (i.e., the side facing away from the mounting plate 11), allowing for a wider range of adjustment for the protrusion heights of the first and second protrusions to accommodate strapping of varying sizes. For example, if the strapping strap of the baler 100 is wider, the corresponding swing amplitude of the lever in the X-axis direction will be greater, requiring a swing wheel 29 with a higher protrusion height. Since the first and second protrusions are located on the outer end surface of the swing wheel 29, the protrusion height of the protrusions and the swinging motion of the swing arm 22 are not restricted, and a swing wheel 29 with protrusions of corresponding heights can be selected and replaced according to actual needs. In addition, the protrusion is arranged on the outside of the swing wheel, so that the swing arm 22 can be located outside the entire toggle assembly. The swing of the swing arm in the X-axis direction will not be interfered with by the toggle assembly, which is suitable for wide band use.

[0064] In this embodiment, the swing wheel 29 and the shift wheel 26 are installed together and driven by the driving main shaft 25 to rotate together, so that the shift rod 21 can swing in the horizontal direction relative to the mounting plate 11 while also being able to move in the front and rear directions relative to the mounting plate 11.

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

[0066] Figure 10 It is a three-dimensional diagram of the lifting assembly 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 column 64, and a first elastic member 65. The lifting component 61 is coupled 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 up and down. The lifting bracket 63 is linked to the drive spindle 25. Driven by the drive spindle 25, the lifting bracket 63 moves up and down. The guide column 64 is fixedly mounted on the mounting plate 11. The first elastic member 65 is a spring that is mounted on the upper end of the outer periphery of the guide column 64. In this embodiment, the movable shaft 23 is a hollow cylinder that is mounted on the outer periphery of the guide column 64. One end of the first elastic member 65 abuts against the movable shaft 23 to help the movable shaft 23 reset.

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

[0069] The lifting roller 62 has a first end face 621, a second end face 622 and a peripheral surface 623. The first end face 621 is combined with the lifting bracket 63, the second end face 622 faces the movable shaft, and there is a gap between the second end face 622 and the movable shaft. The peripheral surface 623 contacts the lower end face of the lifting component 61, and the lifting roller 62 is lifted up by the lifting bracket 63. Since the lifting roller 62 is located on the lower end face of the lifting component 61, the lifting component 61 can be lifted up during the lifting process, prompting the lifting component 61 to move upward with the movable shaft 23, thereby causing the rocker arm 22 to move upward with the shift rod 21.

[0070] Figure 12 It is a structural diagram of the connection between the lifting assembly and the driving spindle of the present invention.

[0071] like Figure 12 As shown, the drive spindle 25 is provided with a first cam 254, and the lifting bracket 63 comprises a movable plate 631, a first slider assembly 632, and a support plate 633. The support plate 633 is L-shaped, with a first roller 53 that cooperates with the first cam 254 provided at one end and the other end fixed to the slider of the first slider assembly 632. The slide rail of the first slider assembly 632 is vertically mounted on the mounting plate 11. One end of the movable plate 631 is mounted on the slider of the first slider assembly 632 and can move up and down along the slide rail with the slider. The other end of the movable plate 631 is used to mount the lifting roller 62. At least two lifting rollers 62 are provided and are evenly arranged on the lower end surface of the lifting component 61, so that the lifting component 61 is evenly stressed when being lifted by the lifting roller 62. In this embodiment, the lifting component 61 is provided separately from the movable shaft 23. The lifting component 61 is in the shape of a hollow ring and is mounted on the upper end of the outer circumference of the movable shaft 23. It is secured to the movable shaft 23 from the circumferential surface by a fixing member. The movable shaft 23 is also provided with a retaining spring at the upper end surface of the lifting component 61 to axially position the movable shaft 23. Because the lifting component 61 is relatively fixed to the movable shaft 23, when the movable shaft 23 rotates (when the rocker arm 22 is driven to swing by the swing assembly), the lifting component 61 also rotates accordingly, generating a planar force between the lower end surface of the lifting component 61 and the circumferential surface of the lifting roller 62. To prevent wear, a cylindrical lifting roller 62 (with the circumferential surface of the lifting roller 62 serving as the contact surface) is used to drive the lifting component 61, thereby better protecting the various components.

[0075] Figure 14 It is a reverse structural diagram of the tool device of the present invention installed on the frame.

[0076] like Figure 14 As shown, the tool device also includes a pressure plate assembly 38 for flattening the strapping tape and pressing it on the bottom of the movable plate 31. The pressure plate assembly 38 comprises: a pressure plate 381, a rotating frame 382 and a crank 383. The pressure plate 381 is movably arranged below the movable plate 31 and is used to press the initial end of the strapping tape onto the movable plate 31; the rotating frame 382 is used to drive the pressure plate 381 to rotate; and the crank 383 is connected to the rotating frame 382.

[0077] Figure 15 It is a structural diagram of the pressing plate assembly of the present invention installed on the frame.

[0078] Figure 16 It is a schematic diagram of the position structure of the pressure plate assembly and the movable plate of the present invention.

[0079] like Figure 15 and Figure 16As shown, the movable plate 31 is provided with a connecting block 311, which is provided with a guide hole 3111. One end of the pressure plate 381 is provided with a latch 3811 that can move within the guide hole 3111. Driven by the rotating frame 382, ​​the pressure plate 381 rotates relative to the connecting block 311 along the guide hole 3111. A slide assembly is also provided between the pressure plate 381 and the rotating frame 382. When the movable plate 31 moves, the connecting block 311 also moves with it. Driven by the connecting block 311, the pressure plate 381 can move relative to the rotating frame 382. Therefore, the pressure plate 381 can both rotate and move. In this embodiment, by providing a slide assembly on the rotating frame, the pressure plate can slide on the rotating upper frame, allowing the pressure plate to move synchronously with the movable plate, thereby adapting to the normal operation of the baling machine. At the same time, the rotation of the rotating frame causes the pressure plate to rotate, thereby achieving the smoothing and compression of the strapping tape. In the prior art, most of the time, a universal bearing structure is used to realize the rotation and forward and backward movement of the smoothing part, but the universal bearing has high precision and installation requirements. This embodiment adopts the above-mentioned rotating structure of the rotating frame and the sliding structure following the movable plate to realize the smoothing and pressing functions. The overall structure is simple and the installation is quick, which effectively reduces the difficulty of product manufacturing.

[0080] The driving spindle 25 is provided with a moving plate cam group 71 and a crank cam group 72 for driving the moving plate 31 and the crank 383 to move, respectively. The crank 383 moves vertically (i.e., in the Z direction) under the drive of the crank cam group 72, and the moving plate 31 moves horizontally (i.e., in the X direction) under the drive of the moving plate cam group 71. Specifically, Figure 14 As shown, the moving plate cam assembly 71 comprises a moving plate cam 711, a moving plate rocker arm 712 and a moving plate roller 713. The moving plate cam 711 is mounted on the driving spindle 25. The moving plate 31 is mounted on one end of the moving plate rocker arm 712 and the moving plate roller 713 is mounted on the other end. The moving plate roller 713 cooperates with the moving plate cam 711. Figure 16 As shown, two fixed blocks 312a and 312b are provided at the bottom of the movable plate 31, wherein a connecting block 311 is fixed to one of the fixed blocks 312a, and a slide rail assembly is provided between the other fixed block 312b and the mounting plate 11, so that the movable plate 31 can move on the frame 10 under the drive of the driving spindle 25, and can drive the pressure plate 381 on the connecting block 311 to move. A tension spring 92 (such as Figure 23 As shown), it is convenient for the mobile plate rocker arm 712 to reset. In addition, in order to enhance the stability of the mobile plate 31 when it moves, a pair of limit blocks 12 (as shown) are provided at the location where the mobile plate 31 is installed on the mounting plate 11 of the frame 10. Figure 9 As shown) and the guide groove 13 (as shown Figure 15As shown in FIG. 1 , the edge of the movable plate 31 near the pressure plate 381 extends into the guide groove 13. The guide groove 13 can guide the movable plate 31 on one hand, and can also limit the left and right sides of the movable plate 31 on the other hand. The limit block 12 is located on the front side of the movable plate 31. The overall shape of the movable plate 31 is a "convex" shape. The limit block 12 is located in the concave part on both sides of the movable plate 31, limiting the movable plate 31 in the direction of forward and backward movement. At the same time, as shown in FIG. Figure 13 As shown, the limit block 12 is in an inverted L-shape, and the horizontal edges of the L-shape can be placed above both sides of the movable plate 31, thereby forming a vertical limit for the movable plate 31, which can limit the upward deformation of the movable plate, effectively reducing the loss of the movable plate caused by the various functional knife blocks at the bottom and the pressure of the pressure plate, thereby effectively increasing the overall life of the movable plate.

[0081] like Figure 14-16 As shown, the crank cam assembly 72 includes a crank cam 721, a crank slide 722, a crank slideway 724, and a crank roller 723.

The crank slide 724 is mounted on the mounting plate 11, and the crank slide 722 slides on the crank slide 724. When the drive spindle 25 rotates with the crank cam 721, the crank roller 723 on the crank slide 722 moves along the outer edge of the crank cam 721, causing the crank slide 722 to slide along the crank slide 724. During this sliding process, the crank 383 drives the rotating frame 382 and the pressure plate 381 on the rotating frame 382 to rotate. A tension spring 93 is provided between the crank slide 722 and the frame 10 to facilitate the reset of the crank slide 722.

Driven by the top block cam assembly 74, the top block 33 moves vertically (i.e., in the Z direction), and driven by the positioning knife cam assembly 73, the positioning knife 32 moves horizontally (i.e., in the X direction). Specifically, the positioning knife cam assembly 73 includes a positioning knife cam 731, a positioning knife rocker arm 732, and a positioning knife roller 733. The positioning knife cam 731 is mounted on the drive spindle 25. The positioning knife 32 is mounted on the positioning knife rocker arm 732 via a sliding assembly. The positioning knife roller 733 is mounted on the positioning knife rocker arm 732 and cooperates with the positioning knife cam 731. When the drive spindle 25 rotates with the positioning knife cam 731, the positioning knife roller 733 on the positioning knife rocker arm 732 moves along the outer edge of the positioning knife cam 731, causing the positioning knife 32 to move upward in the X direction following the positioning knife rocker arm 732. A tension spring 94 (such as Figure 23 As shown, a fixing plate 13 is provided on the frame 10, one end of the tension spring 94 is hooked on the fixing plate 13, and the other end is hooked on the positioning knife rocker arm 732), so as to facilitate the resetting of the positioning knife rocker arm 732.

The ejector 33 is mounted on the ejector connecting rod 742 via an ejector mounting plate 744. The ejector mounting plate 744 is mounted on the mounting plate 11 via a slider assembly. The ejector roller 743 is mounted on the ejector connecting rod 742 and engages with the ejector cam 741. When the drive spindle 25 rotates with the ejector cam 741, the ejector roller 743 on the ejector connecting rod 742 moves along the outer edge of the ejector cam 741, causing the ejector mounting plate 744 to slide along the slider assembly. During this sliding process, the ejector mounting plate 744 drives the ejector 33 in the Z direction. A tension spring is provided between the ejector mounting plate 744 and the frame 10 to facilitate the return of the ejector mounting plate 744.

[0085] Figure 18 It is the structural diagram of positioning knife of the present invention.

[0086] like Figure 18As shown, the positioning knife 32 is F-shaped and has a first cross bar 321, a second cross bar 322 and a vertical bar 323. A sliding space 324 is formed between the second cross bar 322 and the first cross bar 321 for the top block 33 to extend and move. The vertical bar 323 is installed on the positioning knife rocker arm 732 through a slide rail assembly; when the top block 33 moves up to clamp the strapping tape between the top block 33 and the first cross bar 321, the positioning knife 32 can also be pushed up by the top block 33; a tension spring 96 can also be set between the bottom of the vertical bar 323 and the positioning knife rocker arm 732 to pull the positioning knife 32 downward along the sliding assembly on the positioning knife rocker arm 732 for resetting.

[0087] Figure 19 It is a schematic diagram of the installation structure of the ironing knife, cutting knife and pressing block of the present invention.

[0088] like Figure 14 and Figure 19 As shown, the drive spindle 25 is provided with a cam assembly 75 and a pressure block cam assembly 76, which are respectively used to drive the ironing head 36 and the pressure block 37. Driven by the pressure block cam assembly 76, the pressure block 37 moves vertically (i.e., in the Z direction), while driven by the cam assembly 75, the ironing head 36 moves horizontally (i.e., in the X direction) above the pressure block. Specifically, the cam assembly 75 comprises a cam 751, a rocker arm 752, and a roller 753. The cam 751 is mounted on the drive spindle 25, the ironing head 36 is mounted on the rocker arm 752, and the roller 753 is mounted on the rocker arm 752 and cooperates with the cam 751. When the drive spindle 25 rotates with the cam 751, the roller 753 on the rocker arm 752 moves along the outer edge of the cam 751, causing the ironing head 36 to follow the rocker arm 752 and move in the X direction. A tension spring 97 is provided between the ironing head rocker arm 752 and the frame 10 to facilitate the reset of the ironing head rocker arm 752. Figure 23 As shown, one end of the tension spring 97 is hooked on the fixing plate 13 installed on the frame 10, and the other end is hooked on the ironing head rocker arm 752.

[0089] The pressure block cam assembly 76 comprises a pressure block cam 761, a pressure block connecting rod 762, and a pressure block roller 763. The pressure block cam 761 is mounted on the drive spindle 25. The pressure block 37 is mounted on the pressure block connecting rod 762 via a pressure block mounting plate 764. The pressure block mounting plate 764 is mounted on the mounting plate 11 via a slider assembly. The pressure block roller 763 is mounted on the pressure block connecting rod 762 and cooperates with the pressure block cam 761. At the same time, the cutter 34 is also mounted on the pressure block mounting plate 764, so that the cutter 34 can also be driven by the pressure block mounting plate 764. When the drive spindle 25 rotates with the pressure block cam 761, the pressure block roller 763 on the pressure block connecting rod 762 moves along the outer edge of the pressure block cam 761, causing the pressure block mounting plate 764 to slide along the slider assembly. During the sliding process, the pressure block mounting plate 764 drives the cutter 34 and the pressure block 37 to move in the Z direction. A tension spring 98 is provided between the pressure block mounting plate 764 and the frame 10 to facilitate the resetting of the pressure block mounting plate 764 .

[0090] Figure 20 It is a schematic diagram of the installation structure of the clamping block of the present invention.

[0091] The drive spindle 25 is provided with a clamp cam assembly 77 for driving the clamp 35. The clamp cam assembly 77 comprises a clamp cam 771, a clamp connecting rod 772, and a clamp roller 773. The clamp cam 771 is mounted on the drive spindle 25. The clamp is mounted on the clamp connecting rod 772 via a clamp mounting plate 774. A slider assembly is provided between the clamp mounting plate 774 and the mounting plate 10. The clamp roller 773 is mounted on the clamp connecting rod 772 and engages with the clamp cam 771. When the drive spindle 25 rotates with the clamp cam 771, the clamp roller 773 on the clamp connecting rod 772 moves along the outer edge of the clamp cam 771, causing the clamp mounting plate 774 to slide along the slider assembly. During this sliding process, the clamp mounting plate 774 drives the clamp 35 to move in the Z direction. A tension spring 99 is provided between the clamp mounting plate 774 and the frame 10 to facilitate the reset of the clamp mounting plate 774. The slide rail assembly or slider assembly mentioned above is a linear rail assembly formed by a slider and a linear rail, which has a simple and stable structure.

[0092] like Figure 13As shown, a mounting spindle 39 is also provided on the frame. One end of the movable plate rocker arm 712, the ironing head rocker arm 752, and the positioning knife rocker arm 732 is respectively provided with a movable plate sleeve 7121, an ironing head sleeve 7521, and a positioning knife sleeve 7321. The movable plate sleeve 7121, the ironing head sleeve 7521, and the positioning knife sleeve 7321 are all sleeved on the mounting spindle 39. The mounting spindle 39 and the driving spindle 25 are respectively placed on both sides of the mounting plate 11. The pressure block connecting rod 762, the lifting block connecting rod 742, and the clamping block connecting rod 772 are all L-shaped. One end is equipped with the corresponding pressure block roller 763, the lifting block roller 743, and the clamping block roller 773, and the other end is equipped with the corresponding pressure block mounting plate 764, the lifting block mounting plate 744, and the clamping block mounting plate 774. Therefore, the rollers and the mounting plates are also respectively placed on both sides of the mounting plate 11, and the overall structure is compact and the layout is more reasonable. In addition, the pressure block 37, the top block 33 and the clamping block 35 are respectively set on the corresponding pressure block mounting plate 764, the top block mounting plate 744 and the clamping block mounting plate 774 through springs and adjusting nuts, so as to facilitate fine-tuning and movement during operation.

[0093] The lever 21 has a first position and a second position in the process of moving the strapping tape. When the lever 21 swings to the first position, the clamping block 35 moves upward to clamp the strapping tape between the clamping block 35 and the movable plate 31; when the lever 21 swings to the second position, the top block 33 moves upward to clamp the strapping tape between the top block 33 and the positioning knife 32, and then the cutter 34 moves upward to cut the strapping tape; the second position is located in the gap between the ironing head 36 and the cutter 34, and the ironing head 36 hot-melts the strapping tape after the strapping tape is cut by the cutter 34.

[0094] The process of packaging objects by the packaging machine of the present invention is as follows:

[0095] Figure 21 is a schematic diagram of the state of the strapping belt of the strapping machine of the present invention during the strapping process.

[0096] like Figure 21a As 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 area of ​​the movable plate 31). In the initial position, the head end of the strapping tape 83 is clamped between the positioning knife 32 and the top block 33, and the shifting rod 21 is located near the strapping tape 83. The machine is started, and the object 81 begins to move in the direction of the arrow in the figure until one side surface (the left side in the figure) moves beyond the clamping block 35. Then the shifting rod 21 starts to shift the strapping tape for the first time: the shifting rod 21 shifts the strapping tape 83 in the direction of the object 81. Since the shifting rod 21 is in a rotating state, the strapping tape 83 will be shifted to the bottom of the movable plate 31. During this period, the movable plate 31 will move out along the X-axis direction to the top of the strapping tape. During this shifting process, the head end of the strapping tape is always clamped.

[0097] like Figure 21bAs shown, after the strapping tape 83 has wrapped around a portion of the object 81, the lever 21 swings to the first position (at the rear side of the clamping block 35, where the rear side refers to the forward direction of the strapping tape, the initial position is the front, and the position after the lever is moved is the rear). The clamping block 35 moves upward along the Z axis, gradually clamping the first layer of strapping tape 831 between the clamping block 35 and the movable plate 31. After the strapping tape is clamped by the clamping block 35 and the movable plate 31, the lever 21 begins to withdraw, i.e., moves out of the strapping tape and returns to the initial position. At the same time, during the withdrawal 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 head end of the strapping tape 83 is released.

[0098] like Figure 21c After the leading end of the strapping tape 83 is released, the pressing plate 381 rotates to flatten the leading end of the strapping tape 83 and press it tightly between the pressing plate 381 and the movable plate 31. Next, the tape guide device 40 pushes the strapping tape to the bottom of the movable plate 31 to wrap the object. Then, the lever 21 moves the strapping tape 83 a second time, so that the subsequent strapping tape 83 is pressed against the outside of the object and enters under the first layer of strapping tape 831, thereby forming a second layer of strapping tape 832.

[0099] like Figure 21d As shown, in the process of the shifting rod 21 shifting the strapping tape, the second layer of strapping tape 832 is bent at the shifting rod 21 and located on the upper and lower sides of the shifting head 211. At the same time, the pressure plate 381 retreats away from the first layer of strapping tape 831, and the positioning knife 32 and the top block 33 start to move. During this process, the ironing head 36 will also extend below the first layer of strapping tape 831. When the shifting rod 21 moves to the position between the cutter 34 and the ironing head 36 (that is, when it is in the second position), it will stay for a while, the positioning knife 32 and the top block 33 clamp the end of the second layer of strapping tape, and then the cutter 34 moves up to cut the second layer of strapping tape 832 along the top block 33.

[0100] like Figure 21e As shown, after the second layer of strapping tape 832 is cut off, the shifting rod 21 will continue to swing toward the direction of the rotating rod to smooth out the second layer of strapping tape 832 located below the shifting head 211 along the bottom of the ironing head. At the same time, the pressing block 37 is also gradually moving upward, gradually pressing the second layer of strapping tape 832 to the bottom of the ironing head. When the shifting rod 21 is separated from the strapping tape, the ironing head 36 is already located between the first layer of strapping tape 831 and the second layer of strapping tape 832, and then the two layers of strapping tape are hot-melt.

[0101] like Figure 21fAs shown, after hot melting, the ironing head 36 retreats and withdraws from the strapping tape, and the pressing block 37 continues to move upward to press the two layers of strapping tape together. After the strapping tape is pressed together, the movable plate 31, the pressing block 37, and the clamping block 35 are gradually withdrawn and returned to their original positions. The strapping tape located below the movable plate 31 will automatically adhere to the bottom of the object after the movable plate 31 is withdrawn, thereby completing the packaging of the object.
