The terms "first", "second", and "third" are only used to facilitate the description of the present technical solution and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", and "third" can explicitly or implicitly include one or more of these features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0026] like Figures 1 to 4 As shown, a packaging bag shaping machine according to an embodiment of the present invention includes a frame 10 , a driving member 20 and a shaping assembly 30 .

[0027] Specifically, the frame 10 has a first direction and a second direction. A plurality of support rollers 11 are spaced apart on the frame 10 along the first direction. Active rollers 12 and passive rollers 13 are rotatably provided at both ends of the frame 10. A conveyor belt 14 is connected between the active rollers 12 and the passive rollers 13, and the conveyor belt 14 is wound around all of the support rollers 11. A driving member 20 is provided on the frame 10 and is used to drive the active rollers 12 to rotate, thereby driving the conveyor belt 14. The shaping assembly 30 includes a shaping frame 31, a power unit 33, and a plurality of shaping members 32. The shaping frame 31 is movably provided directly above the frame 10. All shaping members 32 are rotatably provided on the shaping frame 31 along the first direction. The power unit 33 is used to drive the shaping members 32 to rotate, thereby shaping the surface of the packaging bag passing thereunder.

[0028] It should be noted that the "multiple shaping members 32" mentioned above refer to one or more, and the specific number can be determined according to actual conditions. For example: if the length of the conveyor belt 14 is short, only one shaping member 32 is required to achieve the shaping of the packaging bags placed on the conveyor belt 14; if the length of the conveyor belt 14 is long, three shaping members 32 need to be set to ensure that the surface of the packaging bags can be better shaped.

[0029] For example, the drive member 20 may be a servo motor that drives the active roller 12 to rotate, thereby driving the conveyor belt 14 to move the packaging bags placed on the conveyor belt 14 from one side of the frame 10 to the other side through the shaping member 32, thereby automatically shaping the surface of the packaging bags. The above is merely an example and is not intended to be limiting. The drive member 20 may also be a conventional power component capable of driving the active roller 12 to rotate.

[0030] In addition, the "first direction" mentioned above refers to the transport direction of the packaging bag, specifically the length direction of the rack 10, which can be referred to Figure 1 The "second direction" refers to the transport direction perpendicular to the packaging bag, specifically the width direction of the rack 10, which can be referred to Figure 1 in the Y direction.

[0031] The packaging bag shaping equipment based on the above-mentioned technical features places the packaging bag to be shaped on the conveyor belt 14, and then drives the active roller 12 to rotate through the driving member 20. Since the conveyor belt 14 is wound between the active roller 12 and the driven roller 13, the conveyor belt 14 is driven to operate to transport the packaging bag placed on the conveyor belt 14 along the first direction. At the same time, the power unit 33 is used to drive the shaping member 32 to rotate, and then the surface of the packaging bag passing under the shaping member 32 is shaped, thereby realizing automatic shaping of the packaging bag, replacing the traditional manual shaping method, which not only reduces labor costs and labor intensity, but also greatly improves the shaping efficiency.

[0032] In one possible embodiment, the power unit 33 includes a power piece 331, a transmission rod 332, a transmission chain, a first transmission tooth 34 and a second transmission tooth 35. The transmission rod 332 is connected to one end of the shaping frame 31 along the second direction, the first transmission tooth 34 is rotatably sleeved on the transmission rod 332, and the second transmission tooth 35 is rotatably provided on the other end of the shaping frame 31. The transmission chain is wound between the first transmission tooth 34 and the second transmission tooth 35. The end of the shaping piece 32 is transmission-connected to the transmission chain. The power piece 331 is fixed on the shaping frame 31 for driving the transmission rod 332 to rotate.

[0033] For example, when a packaging bag passes under the shaping member 32, the power member 331 drives the transmission rod to rotate. Because the transmission rod 332 is sleeved with a first transmission tooth 34, a transmission chain is wound between the first transmission tooth 34 and the second transmission tooth 35. The transmission chain is in driving connection with the end of the shaping member 32, so that the shaping member 32 is driven to rotate on the shaping frame 31, thereby shaping the passing packaging bag. Furthermore, the power member 331 can be a servo motor or any other conventional power component capable of driving the transmission rod 332, without limitation.

[0034] Specifically, the output shaft of the power member 331 is connected to a driving gear 334, a driven gear 333 is sleeved on a transmission rod 332, and a transmission belt is connected between the driven gear 333 and the driving gear 334. In this way, the driving gear 334 can be driven to rotate by the power member 331, and the driven gear 333 can be driven to rotate by the transmission belt, thereby pulling the transmission rod to which the driven gear 333 is sleeved to rotate. This simple structure and easy operation.

[0035] In one possible embodiment, the shaping member 32 includes a shaping roller 321 and a plurality of shaping protrusions 322. Connecting shafts 37 extend from both ends of the shaping roller 321, connecting the connecting shafts 37 to the shaping frame 31. The connecting shafts 37 are provided with third transmission teeth, which are in driving connection with a transmission chain. The shaping protrusions 322 protrude outward from the shaping roller 321 and extend axially along the shaping roller 321. All shaping protrusions 322 are spaced apart around the central axis of the shaping roller 321. In other words, when the transmission chain is driven, the third transmission teeth are driven to rotate, driving the connecting shaft 37, which in turn drives the shaping roller 321. Because the shaping protrusions 322 are spaced apart on the surface of the shaping roller 321, the upper surface of the passing packaging bag contacts the shaping protrusions 322, thereby automatically shaping the packaging bag. This achieves good shaping results, eliminates the need for manual shaping, and reduces labor intensity.

[0036] In one possible embodiment, the lifting assembly 36 is further included. The lifting assembly 36 includes a rotating rod 362 and two vertical beams 361. The two vertical beams 361 are axially symmetrically arranged on the outer edges of the shaping frame 31 and connected to the frame 10. The rotating rods 362 are provided on the two vertical beams 361 in the vertical direction. Connecting plates 363 are connected to the outer sides of the shaping frame 31, and the connecting plates 363 are slidably connected to the rotating rods 362. In other words, by driving the rotating rods 362 to rotate, the shaping frame 31 can be driven to move in the vertical direction, thereby driving the shaping member 32 connected to the shaping frame 31 to move closer to or away from the conveyor belt 14, thereby achieving adaptive adjustment of the shaping height. This solves the problem of difficult and complex shaping height adjustment in current packaging shaping machines, can meet the shaping needs of packaging bags of different sizes, and has good adaptability.

[0037] In one possible embodiment, a rotating handwheel 364 is mounted on the upper end of the rotating rod 362. The rotating handwheel 364 is used to drive the rotating rod 362 to rotate, thereby driving the connecting plate 363 to slide along the extension direction of the rotating rod 362. In this way, the rotating rod 362 can be driven to rotate by rotating the handwheel 364, making it easier for workers to adjust the shaping height.

[0038] In one possible embodiment, the output shaft of the driving member 20 is connected to a driving pulley 40, and a driven pulley 50 is provided at one end of the driving roller 12. A transmission belt 60 is connected between the driven pulley 50 and the driving pulley 40. In other words, after the packaging bag to be shaped is placed on the conveyor belt 14, the driving member 20 drives the driving pulley 40 to rotate, thereby driving the driven pulley 50 to rotate via the transmission belt 60. The driven pulley 50 is sleeved on one end of the driving roller 12 to drive the driving roller 12 to rotate, thereby driving the conveyor belt 14 to operate.

[0039] In one possible embodiment, a plurality of legs 70 are provided on the lower surface of the frame 10, and anti-slip pads 80 are provided at the lower ends of the legs 70. In this way, the frame 10 has good stability and ensures that the packaging bag will not move randomly during the shaping process.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
