Description

Technical Field

[0001] This utility model relates to the field of edge-trimming machine technology, specifically an edge-trimming machine for woven bags. Background Technology

[0002] Woven bags, with their advantages of low cost, high strength, and strong weather resistance, have become widely used packaging containers in many fields such as grain, chemical, building materials, and logistics. In the woven bag production and processing process, "edge sealing" is a key process, which requires heat sealing, sewing, or pressing the bag opening or seam through an edge sealing machine to ensure the airtightness and structural stability of the packaging.

[0003] As downstream industries continue to demand higher packaging efficiency and quality, traditional woven bag edge-trimming machines are gradually revealing numerous technical shortcomings, making it difficult to meet the needs of large-scale, high-precision production. Specific problems include: Inconvenient clamping adjustment of the pressure plate: During the edge sealing process, the upper pressure plate and the lower support plate are needed to clamp the edge of the woven bag to ensure the flatness of the sealing. Traditional equipment often uses manual screw adjustment or single cylinder drive for the upper pressure plate lifting. Manual adjustment is inefficient and it is difficult to ensure that the height of multiple pressure plates is consistent. Although the cylinder drive has a faster response, it is affected by air pressure fluctuations, and the clamping force is unstable. When there are batch differences in the thickness of the woven bag, it is easy to cause "clamping too loosely, causing edge slippage" or "clamping too tightly, causing damage to the woven bag", which affects the sealing quality. Low adaptability: Different industries have different requirements for woven bag specifications. The feeding roller spacing and pressure plate stroke of traditional edge-trimming machines are mostly fixed structures. To adapt to different specifications of woven bags, it is necessary to replace the feeding rollers, adjust the support frame, etc. The modification cycle is long and requires professional technicians to operate, which seriously affects the efficiency of production changeover and makes it difficult to adapt to the flexible production needs of small batches and multiple specifications.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-6 This is the first embodiment of the present utility model, which adopts the following technical solution, including a conveying device 1, a support frame 3 fixedly connected to the right side of the conveying device 1, an edge-trimming machine device 2 fixedly connected to the rear side of the top of the support frame 3, an upper pressure plate 21 provided on the top of the support frame 3, a lower support plate 22 provided at the bottom of the upper pressure plate 21, which is located on the top of the support frame 3 and is level with the horizontal plane of the conveyor belt of the conveying device 1, an mounting frame 31 fixedly connected to the left side of the front side of the support frame 3, two sets of feeding rollers 4 for conveying woven bags provided on the top of the support frame 3, and a feeding support assembly provided on one side of the mounting frame 31 for supporting and conveying the woven bags in conjunction with the lower support plate 22; The pressure plate lifting mechanism is located on the top of the mounting frame 31 and is used to drive the upper pressure plate 21 to lift. The feeding drive mechanism is located on the front side of the lower support plate 22 and is used to drive the feeding roller 4 to rotate. A dual-end drive mechanism is located on the front side of the mounting frame 31 and is used to drive and control the pressure plate lifting mechanism and the feeding drive mechanism.

[0022] Specifically, the feeding support assembly, in conjunction with the lower support plate 22, not only provides stable support for the woven bag in both the upper and lower directions, but also assists the feeding roller 4 in conveying the bag, preventing the bag from sagging or shifting due to lack of effective support before edge sealing. The pressure plate lifting mechanism is specifically responsible for the lifting and adjustment of the upper pressure plate 21, and can flexibly adjust the clamping gap according to the thickness of the woven bag to ensure that the edge of the woven bag is clamped during edge sealing and to prevent slippage during sealing. The feeding drive mechanism provides rotational power to the two sets of feeding rollers 4, ensuring that the feeding rollers 4 can stably convey the woven bag and keep the edge sealing position and speed uniform. The dual-end drive mechanism can uniformly control the operation of the pressure plate lifting mechanism and the feeding drive mechanism, avoiding asynchronous actions caused by independent power.

[0023] Example 2 The second embodiment of this utility model adopts the following technical solution: the feeding support assembly includes a support base 32 and a rotating bracket 33. The support base 32 is fixedly connected to the top right side of the mounting frame 31, and the rotating bracket 33 is fixedly connected to the top of the support frame 3 and its front side is fixedly connected to the support base 32. The feeding roller 4 is rotatably mounted to the rotating bracket 33 on the side near the rotating bracket 33, and the end of the feeding roller 4 near the support base 32 passes through the support base 32 and is rotatably mounted to the support base 32. The pressure plate lifting mechanism includes a second bevel tooth 54, a screw 36, a movable top frame 34, a slide rod 35, and a fixed rod 23. The screw 36 is rotatably mounted on the top of the mounting frame 31. The second conical tooth 54 is fixedly installed at the bottom of the surface of the screw 36 and at the top of the mounting bracket 31. The bottom of the screw 36 is fixedly connected to a retaining ring located at the bottom of the mounting bracket 31. The movable top bracket 34 is threadedly connected to the top of the surface of the screw 36. The sliding rod 35 is fixedly connected to both sides of the top of the support base 32. The top of the sliding rod 35 slides with the movable top bracket 34. Two sets of fixing rods 23 are provided and are fixedly installed on both sides of the back of the movable top bracket 34 and the back of the support base 32, respectively. The movable top bracket 34 is fixedly installed to the upper pressure plate 21 through one set of fixing rods 23. The lower support plate 22 is fixedly installed to the support base 32 through another set of fixing rods 23.

[0024] Specifically, the rotating bracket 33 provides a force to support the feeding roller 4 and facilitates the rotation of the feeding roller 4. At the same time, the support base 32 and the rotating bracket 33 are matched so that both ends of the feeding roller 4 are rotated and supported. The second bevel tooth 54 can be driven to rotate by the double-end drive mechanism, which then drives the screw 36 fixed thereto to rotate. Subsequently, the movable top frame 34 is driven to rise and fall by the screw 36 under the sliding limit of the slide rod 35. Then, the upper pressure plate 21 is driven to rise and fall through the fixed rod 23 to clamp the woven bag mouth, so that the sealing edge of the woven bag mouth is stable. The retaining ring can prevent the screw 36 from moving longitudinally inside the mounting frame 31 when it rotates, ensuring drive stability.

[0025] Example 3 The third embodiment of this utility model adopts the following technical solution: the feeding drive mechanism includes a first synchronous pulley 41, a second synchronous pulley 42, a third synchronous pulley 44, and a second synchronous belt 45. The first synchronous pulley 41 and the second synchronous pulley 42 are respectively fixedly connected to one end of two sets of feeding rollers 4 that pass through the support base 32. The surfaces of the first synchronous pulley 41 and the second synchronous pulley 42 are connected to the first synchronous belt 43 for transmission. One end of one set of feeding rollers 4 near the mounting frame 31 passes through the support base 32 and is fixedly connected to the third synchronous pulley 44. The second synchronous belt 45 is sleeved on the third synchronous pulley 44. The surface of the synchronous pulley 44, the double-end drive mechanism includes a mounting platform 311, a stepper motor 5, a drive shaft 51, a first bevel gear 52, a transmission gear 6, a driven rotary assembly, and a switching assembly. The mounting platform 311 is fixedly connected to the top of the front side of the mounting bracket 31. The stepper motor 5 is fixedly connected to the top of the mounting platform 311. The drive shaft 51 is fixedly connected to the output end of the stepper motor 5. The surface of the drive shaft 51 is provided with a long keyway. The first bevel gear 52 is slidably mounted on the surface of the drive shaft 51. The transmission gear 6 is fixedly connected to the surface of the drive shaft 51 near the stepper motor. On one side of 5, the driven rotating assembly is located on the side of the mounting platform 311 near the third synchronous pulley 44 and is in transmission cooperation with the third synchronous pulley 44. The switching assembly is located on one side of the top of the mounting platform 311 and is used to drive the first bevel gear 52 to slide back and forth, controlling the meshing state of the first bevel gear 52 and the second bevel gear 54. The driven rotating assembly includes a fourth synchronous pulley 46, a driven gear 61, a driven shaft 62, and a gear carrier 63. The fourth synchronous pulley 46 is fixedly connected to one end of the driven shaft 62, and the fourth synchronous pulley 46 is transmitted to the third synchronous pulley 44 through the second synchronous belt 45. The gear carrier 63 is fixedly connected to the side of the mounting platform 311 near the third synchronous wheel 44. The driven shaft 62 is rotatably mounted inside the gear carrier 63. The driven gear 61 is fixedly connected to the surface of the driven shaft 62 and meshes with the transmission gear 6. The switching assembly includes an electromagnetic push rod 55 and a toggle slide rod 53. The electromagnetic push rod 55 is fixedly connected to the top of the mounting platform 311 and is located on one side of the transmission shaft 51. The output end of the electromagnetic push rod 55 is fixedly connected to the toggle slide rod 53. The toggle slide rod 53 slides and limits the engagement with the surface of the first bevel tooth 52.

[0026] Specifically, the third synchronous pulley 44, in conjunction with the second synchronous belt 45, can be rotated by the double-end drive mechanism. Subsequently, the third synchronous pulley 44 drives one set of feeding rollers 4 to rotate, which in turn drives the second synchronous pulley 42, fixed to the surface of the feeding rollers 4, to rotate. Then, the second synchronous pulley 42, via the first synchronous belt 43, can drive the first synchronous pulley 41, which is in transmission with it, to rotate. This causes the feeding rollers 4 on the first synchronous pulley 41 and the feeding rollers 4 on the second synchronous pulley 42 to rotate synchronously, feeding the woven bag. The mounting platform 311 can support and mount the stepper motor 5. After the stepper motor 5 starts, it can drive the drive shaft 51 to rotate, which in turn drives the first bevel gear 52 to rotate. When the second bevel tooth 54 needs to be driven, the switching component can be used to push the first bevel tooth 52 towards the second bevel tooth 54, causing the first bevel tooth 52 to mesh with the second bevel tooth 54 and drive the second bevel tooth 54 to rotate. After the height of the upper pressure plate 21 is adjusted, the switching component can be activated again to drive the first bevel tooth 52, causing the first bevel tooth 52 to separate from the second bevel tooth 54, thereby causing the second bevel tooth 54 to lose its rotational driving force. When the transmission shaft 51 rotates, the rotation of the transmission gear 6 can drive the driven rotation component to drive the third synchronous wheel 44, so that the two sets of feeding rollers 4 rotate synchronously to achieve feeding. After the transmission gear 6 rotates, it can drive the driven gear 61 that meshes with it to rotate. Furthermore, the driven shaft 62 rotates due to the support of the gear frame 63, which in turn drives the fourth synchronous pulley 46, which is fixed coaxially with it, to rotate. The fourth synchronous pulley 46, in conjunction with the second synchronous belt 45, drives the third synchronous pulley 44 to rotate. Subsequently, the third synchronous pulley 44 drives one set of feeding rollers 4 to rotate, which in turn drives the second synchronous pulley 42, which is fixed on the surface of the feeding roller 4, to rotate. Then, the second synchronous pulley 42, through the first synchronous belt 43, drives the first synchronous pulley 41, which is in conjunction with it, to rotate. This causes the feeding rollers 4 on the first synchronous pulley 41 and the feeding rollers 4 on the second synchronous pulley 42 to rotate synchronously to feed the woven bag. After the electromagnetic push rod 55 is activated, it can drive the sliding rod 53 to move the first synchronous pulley 41. The bevel tooth 52 slides back and forth on the surface of the drive shaft 51. Since the rotation of the first bevel tooth 52 is not affected by the sliding rod 53, the first bevel tooth 52 can be driven to rotate through the long keyway when it is pushed to engage with the second bevel tooth 54. This rotation drives the second bevel tooth 54 to rotate, and the second bevel tooth 54 to rotate. The second bevel tooth 54 then drives the screw 36 to rotate, which in turn drives the movable top frame 34 to adjust its height. After the height adjustment is completed, the electromagnetic push rod 55 is controlled to move the sliding rod 53 backward. The sliding rod 53 then moves the first bevel tooth 52 backward and separates it from the second bevel tooth 54, so that the second bevel tooth 54 loses the driving force of the first bevel tooth 52, thus completing the adjustment of the height.

[0027] Working principle: This woven bag edge-trimming machine achieves stable conveying, stable clamping, and efficient edge trimming of woven bags through the coordinated operation of multiple mechanisms. The specific workflow is as follows: Phase one involves adjusting the pressure plate height. Based on the thickness of the woven bag to be processed, the initial distance between the upper pressure plate 21 and the lower support plate 22 is adjusted to ensure that the woven bag is not damaged during clamping while maintaining stability. The switching component in the double-end drive mechanism is activated, energizing the electromagnetic push rod 55, which extends and pushes the sliding rod 53 to drive the first bevel tooth 52 forward along the long keyway of the drive shaft 51 until the first bevel tooth 52 fully engages with the second bevel tooth 54 in the pressure plate lifting mechanism. Then, the stepper motor 5 is activated, driving the drive shaft 51 to rotate. This rotation, via the long keyway, drives the first bevel tooth 52 to rotate synchronously, thereby rotating the engaged second bevel tooth 54. Finally, the pressure plate lifting is adjusted. The second bevel tooth 54 drives the screw 36 to rotate. The retaining ring at the bottom of the screw 36 restricts its longitudinal movement to ensure stable transmission. The movable top frame 34, which is threaded to the screw 36, moves up and down along the screw 36 axis under the sliding limit action of the slide rod 35. The movable top frame 34 drives the upper pressure plate 21 to move up and down synchronously through the fixed rod 23 until the distance between the upper pressure plate 21 and the supporting lower plate 22 matches the thickness of the woven bag. Then, it switches to the feeding drive state, the stepper motor 5 stops, the electromagnetic push rod 55 is de-energized and retracts, and the sliding rod 53 is pulled to drive the first bevel tooth 52 to slide backward along the transmission shaft 51, completely separating from the second bevel tooth 54. At this time, the pressure plate lifting mechanism maintains the current height and waits for the woven bag to be conveyed. Phase two involves conveying the woven bags. In this phase, the feeding drive mechanism drives the feeding roller 4 to rotate synchronously, conveying the woven bags to the edge-trimming station. Power transmission is initiated, and the stepper motor 5 restarts, driving the drive shaft 51 to rotate. At this point, the first bevel gear 52 has separated from the second bevel gear 54. Power is transmitted to the driven rotating assembly via the transmission gear 6 fixed on the drive shaft 51. The driven assembly is activated, and the transmission gear 6 meshes with the driven gear 61, driving the driven shaft 62 to rotate within the gear frame 63. The gear frame 63 ensures the coaxiality of the driven shaft 62. The fourth synchronous pulley 46 at one end of the driven shaft 62 rotates synchronously, and the feeding roller 4 rotates synchronously. The fourth synchronous pulley 46 is connected to the second synchronous pulley 51. The step belt 45 drives the third synchronous wheel 44 in the feeding drive mechanism to rotate. The third synchronous wheel 44 is fixedly connected to one of the feeding rollers 4, thereby driving the feeding roller 4 to rotate. The second synchronous wheel 42 at the end of the feeding roller 4 drives the first synchronous wheel 41 at the end of the other feeding roller 4 to rotate through the first synchronous belt 43, thus realizing the synchronous reverse rotation of the two sets of feeding rollers 4 and stable conveying. The woven bag is conveyed to the top of the support frame 3 by the conveying device 1. The support base 32 and the rotating bracket 33 in the feeding support assembly realize double-end rotation support for the feeding roller 4. Under the clamping of the two sets of synchronously rotating feeding rollers 4, the woven bag is smoothly conveyed to the edge-trimming station of the edge-trimming machine device 2. Phase three involves edge clamping and edge sealing. When the edge of the woven bag reaches the edge sealing station, the equipment pauses feeding and clamps the edge of the woven bag using the pressure plate lifting mechanism. This, combined with the edge sealing machine 2, completes the edge sealing. The pressure plate lifting is restarted, the stepper motor 5 pauses, and the electromagnetic push rod 55 is energized again and extends, pushing the first bevel tooth 52 to mesh with the second bevel tooth 54. The stepper motor 5 rotates in the reverse direction, causing the screw 36 to rotate in the reverse direction. The movable top frame 34 moves downward along the slide rod 35, and through the fixed rod 23, it drives the upper pressure plate 21 to press the woven bag downward (support). The lower plate 22 is level with the conveyor belt of the conveyor device 1 to ensure that the edge of the woven bag is wrinkle-free. During the edge-sealing operation, the edge-sealing machine device 2 is started to heat-seal or sew the edge of the clamped woven bag. Since the clamping force of the upper pressure plate 21 and the supporting lower plate 22 is stable and the woven bag is free from deviation and wrinkles, a good edge-sealing effect can be guaranteed. After clamping and releasing, the stepper motor 5 rotates in the forward direction, driving the upper pressure plate 21 to return to the initial distance. The electromagnetic push rod 55 retracts, and the first bevel tooth 52 and the second bevel tooth 54 separate. Phase four is the reset to complete the cycle. After the upper pressure plate 21 is reset, the stepper motor 5 starts again and drives the feeding roller 4 to rotate through the feeding drive mechanism, which transports the finished woven bag to the next process. At the same time, the conveying device 1 transports the next woven bag to be processed to the feeding roller 4, and the equipment enters the next edge-trimming cycle.
