Description

Technical Field

[0001] This application relates to the field of bag making machine technology, and more specifically, to a waste recycling device for bag making machines. Background Technology

[0002] A bag-making machine is a device that can produce various types of plastic bags, such as flat bags, vest bags, and zipper bags. Bag-making machines typically use plastic film rolls as raw materials, cutting and sealing them according to the required size and shape. During the bag-making process, some waste materials, such as scraps, are generated.

[0003] In related technologies, to facilitate the winding and recycling of excess waste generated by bag-making machines, for example, the patent with prior art announcement number CN213140924U provides a waste collection device for a fully automatic bag-making machine. During operation, one end of the waste edge is connected to the winding core. The drive assembly drives the winding shaft to rotate, which in turn drives the winding core to rotate, thereby winding the waste edge onto the winding core. This automates the waste edge winding operation, improving work efficiency. It facilitates the centralized collection of waste edges and makes the working environment cleaner. Furthermore, the drive motor drives the winding shaft to rotate, which in turn drives the main gear to rotate. This, in turn, drives the secondary gear to rotate simultaneously via a chain, ensuring that the waste edge is uniformly wound during the winding process, improving the efficiency and quality of the winding work.

[0004] Although the existing technical solution mentioned above can achieve the effect of evenly winding the waste material on the outside of the take-up shaft by driving the take-up core to rotate through the drive motor and moving the waste material on the outside of the take-up core through the lead screw, the take-up core is fixed to the outside of the take-up shaft by the bolts on the outside of the limit ring. When the take-up core is replaced, it is necessary to disassemble the completed take-up core with bolts and replace it before the waste material can be continued to be wound. This results in a time-consuming process of replacing the take-up core. Summary of the Invention

The slide rail is fixedly arranged on the outer side of the rotating disk.

[0037] As an optional solution to the technical solution of this application, a slider is slidably provided on the inner side of the end of the take-up shaft near the drive shaft, a tension spring is fixedly provided on the side of the slider away from the drive shaft, the other end of the tension spring is fixedly provided inside the take-up shaft, a telescopic shaft is fixedly provided on the other end of the slider, a flower shaft is fixedly provided on the other end of the telescopic shaft, and a wedge block is rotatably provided on the outer side of the telescopic shaft, and the wedge block is slidably provided on the outer side of the rotating disk parallel to the axial direction of the telescopic shaft;

[0038] A fixing ring is fixedly installed on the top of the support. An arc-shaped protrusion is fixedly installed on the side of the fixing ring away from the rotating disk.

[0039] By adopting the above technical solution, when the rotating disk drives the take-up shaft to rotate upward, the rotating disk simultaneously drives the wedge block to slide along the fixed ring. When the wedge block approaches the arc-shaped protrusion, the wedge block gradually stretches the telescopic shaft towards the drive shaft. At this time, the slider stretches the tension spring, and the swivel at one end of the telescopic shaft slides along the outer side of the conical disk. When the swivel slides to align with the shaft hole, the wedge block is pulled to the telescopic shaft to its maximum extent under the action of the arc-shaped protrusion, and the drive shaft automatically engages with the swivel under the action of spring B. When replacing the take-up core on the outside of the take-up shaft, the rotating disk drives the take-up shaft to continue rotating, causing the swivel to drive the support block to slide inside the limit sleeve through the drive shaft. At this time, the support block compresses the spring C, and the wedge block gradually disengages from the outer side of the arc-shaped protrusion. The tension spring gradually pulls the telescopic shaft back to slide inside the take-up shaft, eventually causing the swivel to disengage from the inside of the shaft hole. At this time, spring C pushes the support block to automatically reset, while the rotating disk continues to drive the take-up shaft to rotate for replacement, achieving the effect of automatically disconnecting the take-up shaft and drive shaft during replacement.

[0040] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0041] (1) This application provides a take-up shaft inside the rotating disk, and a take-up core can be detachably provided on the outside of each take-up shaft. After the rotating disk rotates at a certain angle, the take-up shaft and the take-up core can be automatically replaced. After replacement, the take-up shaft automatically connects with the transmission shaft, so that the transmission shaft drives the take-up shaft and the take-up core to rotate under the drive of the motor to continue to take up the waste material. This solves the problem of the long time required to replace the take-up core, and the take-up core to be replaced can be quickly switched, reducing the time required to disassemble and replace the two take-up cores.

[0042] (2) This application provides a removable winding core on the outside of the winding shaft so that the winding core can be replaced and disassembled from the winding shaft. When the winding shaft drives the winding core to rotate and wind up the waste material, the winding shaft simultaneously drives the winding core to slide along the axial direction so that the waste material can be evenly wound on the outside of the winding core.

[0043] (3) This application provides a drive shaft at the top of the support. When the rotating disk drives the winding shaft to approach the drive shaft, the drive shaft can easily connect with the winding shaft, so that the motor drives the winding shaft to rotate through the drive shaft. When the rotating disk drives the winding shaft to continue to rotate, it can automatically separate from the drive shaft, so that the winding shaft can be automatically separated from the drive shaft when the winding core is replaced.

[0044] (4) This application provides a clutch assembly between the output end of the motor and the rotating disk so that after the motor drives the rotating disk to rotate, the transmission between the rotating disk and the motor can be disconnected by the clutch assembly. At this time, the motor can drive the transmission shaft to drive the winding shaft to rotate in both directions, so that the winding shaft drives the winding core to evenly wind and wind the separation.

[0060] The present application will be further described in detail below with reference to the accompanying drawings.

[0061] Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 9 This application discloses a waste recycling device for a bag-making machine, including a support 1. A rotating disk 2 is rotatably arranged between the side plates on both sides of the support 1. A driving component for driving the rotating disk 2 to rotate is fixedly arranged on one side of the support 1. In this application, the driving component is a motor 3. The output end of the motor 3 is connected to the rotating disk 2 through a clutch assembly. A winding shaft 4 is arranged in a ring array on the inner side of the rotating disk 2. The winding shafts 4 are all rotatably arranged with the rotating disk 2. A winding core 5 is detachably arranged on the outer side of the winding shaft 4. A slide rail 24 for supporting the sliding of the winding core 5 is fixedly arranged on the outer side of the rotating disk 2. A transmission shaft 6 is rotatably arranged on the top of one side of the support 1. The rotating disk 2 drives the winding shafts 4 to engage with the transmission shaft 6 under the drive of the motor 3. Subsequently, the motor 3 drives the transmission shaft 6 to drive the winding shafts 4 through the transmission assembly. When the winding shafts 4 drive the winding cores 5 to rotate, they simultaneously drive the winding cores 5 to slide along the slide rail 24.

[0062] When replacing the take-up core 5, the motor 3 drives the rotating disk 2 to rotate at a certain angle through the clutch assembly, causing the rotating disk 2 to automatically engage with the take-up shaft 4 on the top of the support 1. At this time, the motor 3 drives the drive shaft 6 to rotate, causing the drive shaft 6 to rotate, which in turn drives the take-up shaft 4 to rotate. The take-up shaft 4 then drives the take-up core 5 to rotate and take up the waste material. At the same time, the take-up shaft 4 drives the take-up core 5 to slide along the slide rail 24, so that the waste material is evenly wrapped around the outside of the take-up core 5. When the take-up core 5 moves to one end of the slide rail 24, the motor 3 reverses to reset the take-up core 5. When replacing the take-up core 5 again, the output end of the motor 3 is connected to the rotating disk 2 through the clutch assembly, causing the motor 3 to drive the rotating disk 2 to rotate at a certain angle again. At this time, the rotating disk 2 drives the take-up shaft 4 to automatically disengage from the drive shaft 6. This process is repeated. When the rotating disk 2 drives the take-up shaft 4 to rotate, it can automatically engage and disengage with the drive shaft 6, which facilitates the quick replacement of the take-up core 5 and reduces the time spent on replacing the take-up core 5.

[0063] Reference Figure 1 , Figure 4 and Figure 5 A rotating shaft 21 is fixedly installed on the inner side of the rotating disk 2. The rotating shaft 21 is rotatably installed between the side plates of the support 1. A connecting cylinder 22 is coaxially fixedly installed on the end of the rotating shaft 21 near the motor 3. The connecting cylinder 22 has evenly spaced slots 23 on its inner side.

[0064] The clutch assembly includes a fixing member 32, which is fixedly mounted to the output end of the motor 3 via a drive shaft 31. A pawl 34 is rotatably mounted on one side of the fixing member 32 via a pin 33. The other end of the pawl 34 is engaged with the inner side of the slot 23. An arc-shaped sliding hole 35 is provided on the inner side of the pawl 34. A solenoid valve body 36 is fixedly mounted on the side of the fixing member 32 near the pawl 34. A sliding pin 37 is fixedly mounted on the output end of the solenoid valve body 36. The sliding pin 37 is slidably mounted on the inner side of the arc-shaped sliding hole 35. A spring A38 is fixedly mounted between the fixing member 32 and the pawl 34 on the outer side of the solenoid valve body 36.

[0065] When motor 3 drives the rotating disk 2 to rotate, the solenoid valve body 36 is de-energized to release its attraction to the sliding pin 37. At this time, the spring A38 pushes the sliding pin 37 to slide inside the arc-shaped sliding hole 35, causing the sliding pin 37 to push the claw 34 to elastically press against the inside of the connecting cylinder 22. When motor 3 drives the fixing part 32 to engage the claw 34 with the slot 23 inside the connecting cylinder 22, the fixing part 32 drives the connecting cylinder 22 to rotate through the claw 34, which in turn drives the rotating disk 2 to start rotating. After the rotating disk 2 rotates to a certain angle, it drives the winding shaft 4 to automatically connect with the transmission shaft 6. At this time, the solenoid valve body 36 is energized to attract the sliding pin 37, causing the sliding pin 37 to drive the claw 34 away from the inside of the slot 23, so that motor 3 cannot drive the rotating disk 2 to continue rotating.

[0066] Reference Figure 1 , Figure 2 , Figure 3 and Figure 9 The drive shaft 6 has a shaft hole 61 at one end near the take-up shaft 4. The inner side of the shaft hole 61 is provided with a groove 62 that cooperates with one end of the take-up shaft 4. A conical disk 63 is rotatably provided on the outer side of the drive shaft 6. A gear 64 is fixedly provided on the outer side of the drive shaft 6. A bearing ring 65 is rotatably provided at the other end of the drive shaft 6. The bearing ring 65 is slidably provided on the inner side of the support block 66 along the axial direction. The support block 66 is located at the top of the support 1. A spring B67 is provided on the outer side of the drive shaft 6 between the gear 64 and the support block 66.

[0067] When the rotating disk 2 drives the take-up shaft 4 to approach one end of the drive shaft 6, one end of the take-up shaft 4 first contacts the outer side of the conical disk 63 and squeezes the conical disk 63 to push the bearing ring 65 to slide inside the support block 66. At this time, the drive shaft 6 compresses the spring B67 through the gear 64. When the drive shaft 6 rotates to the position of the shaft hole 61, the spring B67 pushes the gear 64 to drive the drive shaft 6 to automatically approach the end of the take-up shaft 4, so that one end of the take-up shaft 4 is first located inside the shaft hole 61, which achieves the effect of facilitating the docking of the take-up shaft 4 and the drive shaft 6.

[0068] Reference Figure 3 A gear ring 39 is meshed on the outer side of the gear 64. The gear ring 39 is driven by the drive shaft 31 and is located at the output end of the motor 3. The thickness of the gear 64 is greater than the thickness of the gear ring 39.

[0069] When the gear ring 39 drives the gear 64 to rotate, the gear 64 drives the groove 62 on the inner side of the transmission shaft 6 to automatically engage with one end of the take-up shaft 4, so that the transmission shaft 6 can drive the take-up shaft 4 to start rotating. When the transmission shaft 6 drives the gear 64 to slide, the gear 64 slides on the outer side of the gear ring 39, so that the gear 64 always maintains a meshing state with the gear ring 39.

[0070] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 A slider 49 is slidably disposed on the inner side of the end of the take-up shaft 4 near the drive shaft 6. A tension spring 411 is fixedly disposed on the side of the slider 49 away from the drive shaft 6. The other end of the tension spring 411 is fixedly disposed inside the take-up shaft 4. A telescopic shaft 410 is fixedly disposed on the other end of the slider 49. A flower shaft 412 is fixedly disposed on the other end of the telescopic shaft 410. A wedge block 413 is rotatably disposed on the outer side of the telescopic shaft 410. The wedge block 413 is slidably disposed on the outer side of the rotating disk 2 parallel to the axial direction of the telescopic shaft 410.

[0071] A fixing ring 11 is fixedly installed on the top of the support 1. An arc-shaped protrusion 12 is fixedly installed on the side of the fixing ring 11 away from the rotating disk 2. The arc-shaped protrusion 12 is located on the top of the fixing ring 11. The side of the arc-shaped protrusion 12 away from the rotating disk 2 is slidably disposed with the wedge block 413. A limit sleeve 13 is fixedly installed on the top of the support 1. A support block 66 is slidably disposed inside the limit sleeve 13. A spring C68 is fixedly installed on the side of the support block 66 located in the rotation direction of the rotating disk 2. The other end of the spring C68 is fixedly disposed inside the limit sleeve 13. A shell 14 is fixedly installed on the outside of the support 1.

[0072] When the rotating disk 2 drives the take-up shaft 4 to rotate upward, the rotating disk 2 simultaneously drives the wedge block 413 to slide along the fixed ring 11. When the wedge block 413 approaches the arc-shaped protrusion 12, the wedge block 413 gradually stretches the telescopic shaft 410 towards the drive shaft 6. At this time, the slider 49 stretches the tension spring 411, and the flower shaft 412 at one end of the telescopic shaft 410 slides along the outer side of the conical disk 63. When the flower shaft 412 slides to align with the shaft hole 61, the wedge block 413 is pulled to the maximum extent by the arc-shaped protrusion 12, and the drive shaft 6 automatically engages with the flower shaft 412 under the action of the spring B67. When replacing the take-up core 5 on the outside of the take-up shaft 4, the take-up shaft 4 continues to rotate via the rotating disk 2, causing the spool 412 to slide inside the limit sleeve 13 via the drive shaft 6. At this time, the support block 66 compresses the spring C68, and the wedge block 413 gradually disengages from the outside of the arc protrusion 12. The tension spring 411 gradually pulls the telescopic shaft 410 back to slide inside the take-up shaft 4, eventually causing the spool 412 to disengage from the shaft hole 61. At this time, the spring C68 pushes the support block 66 to automatically reset, while the rotating disk 2 continues to drive the take-up shaft 4 to rotate for replacement, achieving the effect of automatically disconnecting the take-up shaft 4 and the drive shaft 6 during replacement.

[0073] Reference Figure 1 , Figure 6 and Figure 7 A lead screw 41 is fixedly installed at the other end of the take-up shaft 4. A bearing inner ring 42 is threaded on the outside of the lead screw 41. A bearing outer ring 43 is rotatably installed on the outside of the bearing inner ring 42. A clamp 44 for fixing the take-up core 5 is symmetrically rotatably installed on the outside of the bearing outer ring 43. A limit groove 45 is opened on the outside of the lead screw 41 parallel to the axial direction. The limit groove 45 is slidably installed on the inside of the take-up core 5. A bracket 46 is fixedly installed on the outside of the bearing inner ring 42. A slide plate 47 is fixedly installed at the other end of the bracket 46. The slide plate 47 is slidably installed on the inside of the slide rail 24.

[0074] The limiting groove 45 on the outside of the lead screw 41 allows the take-up core 5 to be sleeved on the outside of the lead screw 41. At this time, the take-up shaft 4 can drive the take-up core 5 to rotate and take it up through the lead screw 41. The lead screw 41 also drives the inner ring 42 of the bearing to move, so that the inner ring 42 of the bearing drives the slide plate 47 to slide along the slide rail 24 through the bracket 46. This causes the inner ring 42 of the bearing to push the take-up core 5 to slide along the limiting groove 45, achieving the effect of evenly winding the waste material during the rotation and winding process.

[0075] Reference Figure 6 and Figure 7 Both ends of the winding core 5 are fixedly provided with end plates 51. One end plate 51 is fixed to one side of the bearing outer ring 43 by a clamp 44. Anti-slip pins 52 are fixedly provided on the opposite sides of the end plates 51. The anti-slip pins 52 are inserted into the inner side of the bearing outer ring 43.

[0076] A roller 48 is rotatably mounted on the side of the slide plate 47 near the other end plate 51, and the roller 48 is fitted against the outer side of the end plate 51.

[0077] The end plate 51 of one end of the winding core 5 is fixed to the outside of the bearing outer ring 43 by the gripper 44, which prevents the winding core 5 from moving axially during the winding process, and ensures the stability of the other end of the winding core 5 with the support of the roller 48.

[0078] Reference Figure 6 and Figure 7 The outer side of the gripper 44 is provided with a connecting foot 441, which is fixedly provided on the outer side of the connecting ring 442. The connecting ring 442 is threaded on the outer side of the bolt 443, and the bolt 443 is rotatably provided on the outer side of the bearing outer ring 43.

[0079] By rotating the bolt 443 on the outside of the bearing outer ring 43, the connecting ring 442 is driven to move closer to the bearing outer ring 43, so that the connecting ring 442 pushes the clamp 44 to rotate on the outside of the bearing outer ring 43 through the connecting foot 441, so that the clamp 44 releases the fixation of the end plate 51, and then the winding core 5 can be disassembled from the outside of the lead screw 41. Conversely, the end plate 51 and the bearing outer ring 43 can be fixed to each other.

[0080] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A sliding frame 25 is fixedly installed at the other end of the slide rail 24. The sliding frame 25 is fixedly installed on the outside of the rotating shaft 21 through the connecting plate 26, and the sliding frame 25 is slidably installed on the outside of the slide plate 47.

[0081] When the inner bearing ring 42 pushes the take-up core 5 to move axially, the inner bearing ring 42 pushes the slide plate 47 to slide along the slide rail 24. When the slide plate 47 slides to its maximum extent, it is located between the sliding frame 25 and the rotating disk 2, which ensures the stability of the support of the take-up core 5 by the slide plate 47 and prevents the take-up core 5 from being damaged by the lead screw 41 and the slide plate 47 as the waste material is wound up.

[0082] Reference Figure 1 , Figure 4 and Figure 6 Four supports 46 are arranged in a ring array on the outer side of the inner ring 42 of the bearing. Slide plates 47 are fixedly arranged on the outer side of each support 46. Rollers 48 are rotatably arranged on the other side of the slide plate 47 near the end plate 51. Slide rails 24 are slidably arranged on the outer side of each slide plate 47. Slide rails 24 are fixedly arranged on the outer side of the rotating disk 2.

[0083] By setting four slide rails 24 to support four slide plates 47, the take-up shaft 4 and the take-up core 5 are still supported by the slide plates 47 after rotating to the bottom, ensuring the stability of the take-up core 5 after replacement.

[0084] In summary, when the waste recycling device for a bag-making machine disclosed in this application is in use, the uppermost take-up shaft 4 drives the outer take-up core 5 to take up the waste. When the take-up core 5 is replaced, the solenoid valve body 36 is de-energized to release its adsorption on the sliding pin 37. At this time, the spring A38 pushes the sliding pin 37 to slide inside the arc-shaped sliding hole 35, causing the sliding pin 37 to push the claw 34 to elastically press against the inside of the connecting cylinder 22. When the motor 3 drives the fixing member 32 to engage with the claw 34 in the slot 23 inside the connecting cylinder 22, the fixing member 32 drives the connecting cylinder 22 to rotate through the claw 34, which in turn drives the rotating disk 2 to start rotating. The rotating disk 2 drives the uppermost take-up shaft 4 to continue rotating, allowing the flower shaft 412 to pass through. The drive shaft 6 drives the support block 66 to slide inside the limiting sleeve 13. At this time, the support block 66 compresses the spring C68, and the wedge block 413 gradually disengages from the outer side of the arc-shaped protrusion 12. The tension spring 411 gradually pulls the telescopic shaft 410 back to slide inside the take-up shaft 4, eventually causing the flower shaft 412 to disengage from the shaft hole 61. At this time, the spring C68 pushes the support block 66 to automatically reset, while the rotating disk 2 continues to drive the take-up shaft 4 to rotate for replacement, achieving the effect of automatically disconnecting the take-up shaft 4 and the drive shaft 6 during replacement. When the next take-up shaft 4 rotates upward, the rotating disk 2 simultaneously drives the wedge block 413 to slide along the fixing ring 11. When the wedge block 413 approaches the arc-shaped protrusion 12, the wedge block 413 gradually stretches the telescopic shaft 410 towards the drive shaft 6. As shaft 6 approaches, slider 49 stretches spring 411, and the decorative shaft 412 at one end of telescopic shaft 410 slides along the outer side of conical disk 63, squeezing conical disk 63 and pushing bearing ring 65 to slide inside support block 66. At this time, drive shaft 6 compresses spring B67 through gear 64. When decorative shaft 412 slides to align with shaft hole 61, wedge block 413 is pulled to maximum extent by arc protrusion 12, and spring B67 drives gear 64 to automatically move drive shaft 6 closer to end of take-up shaft 4, so that one end of take-up shaft 4 is first located inside shaft hole 61. When gear ring 39 drives gear 64 to rotate, gear 64 drives the decorative groove 62 inside drive shaft 6 to automatically align with one end of take-up shaft 4. The ends cooperate with each other, so that the drive shaft 6 can drive the take-up shaft 4 to start rotating; then the solenoid valve body 36 is energized to attract the sliding pin 37, so that the sliding pin 37 drives the claw 34 away from the inside of the slot 23, so that the motor 3 cannot drive the rotating disk 2 to continue rotating. At this time, the motor 3 can drive the gear 64 to rotate in both directions through the gear ring 39. The gear 64 drives the take-up shaft 4 to rotate through the drive shaft 6. At this time, the take-up shaft 4 can drive the take-up core 5 to rotate and take up the winding through the lead screw 41. The lead screw 41 synchronously drives the inner ring 42 of the bearing to move, so that the inner ring 42 of the bearing drives the slide plate 47 to slide along the slide rail 24 through the bracket 46, so that the inner ring 42 of the bearing pushes the take-up core 5 to slide along the limiting groove 45, thus achieving the effect of evenly winding the waste material during the rotation and winding process.

[0085] The replaced take-up core 5 is moved to the lower position, and the end plate 51 at one end of the take-up core 5 is fixed to the outside of the bearing outer ring 43 by the clamp 44. By rotating the bolt 443 on the outside of the bearing outer ring 43, the connecting ring 442 is driven to move closer to the bearing outer ring 43, so that the connecting ring 442 pushes the clamp 44 to rotate on the outside of the bearing outer ring 43 through the connecting foot 441, so that the clamp 44 releases the fixation of the end plate 51, and the take-up core 5 can be disassembled from the outside of the lead screw 41. Conversely, the end plate 51 and the bearing outer ring 43 can be fixed to each other.
