Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to an automatic collection device for cutting waste from woven bag rolls. Background Technology

[0002] In the production of woven bags, the cutting of rolled fabric is a critical process that generates a large amount of waste. If not handled properly, it will not only affect the production environment but may also lead to reduced production efficiency and increased risk of equipment failure. To solve these problems, various automatic collection devices for woven bag rolled fabric cutting waste have emerged on the market. However, existing devices still have many areas for improvement in the cutting blade-related parts, especially in the quick-release component of the cutting blade.

[0003] Currently, common automatic waste collection devices for woven bag rolls mainly consist of a waste collection mechanism, a conveying system, a centralized storage device, and a power and control unit. The waste collection mechanism typically uses a negative pressure suction port or a mechanical feeder to capture waste at the moment of cutting. The conveying system transports the waste from the cutting station to the storage area through airflow or mechanical conveying. The centralized storage device is responsible for temporarily storing the waste, and some also have compression or packaging functions for subsequent recycling. The power and control unit provides power to each component and realizes automated linkage control. However, these devices have exposed a series of problems related to the cutting blade in actual use.

[0004] The existing cutting blade is tightly fixed to the blade holder by multiple bolts. When the cutting blade needs to be replaced due to wear, dulling, or damage after prolonged use, the operator has to use multiple tools and spend a lot of time and effort to unscrew these bolts one by one. According to actual operation statistics, completing such a cutting blade replacement undoubtedly seriously affects the continuity and efficiency of production. At the same time, frequent disassembly operations can easily damage the threads of the bolts and blade holder, reducing their service life and further increasing equipment maintenance costs.

[0031] Please see Figures 1-4 This utility model provides a technical solution: an automatic collection device for woven bag roll cutting waste, including a support base 1, a feeding roller 3, a rolling roller 10, a tensioning roller 12 and two sliding seats 8;

[0032] Limiting components are provided on both sliding seats 8;

[0033] The limiting assembly includes a cutting blade 13, a hydraulic telescopic rod 15, and two rotating threaded rods 16. A mounting base 19 is fixedly installed at the output end of the hydraulic telescopic rod 15. A cutting blade groove 5 is formed on the lower surface of the mounting base 19. The upper outer wall of the cutting blade 13 is slidably connected to the inside of the cutting blade groove 5. Second limiting block grooves 17 are formed on both inner walls of the cutting blade groove 5. Limiting blocks 18 are slidably connected inside the two second limiting block grooves 17. First limiting block grooves 14 are formed on both outer walls of the upper end of the cutting blade 13. The two limiting blocks 18... The ends of the two rotating threaded rods 16 near the first limiting block groove 14 are slidably extended into the interior of the cutting blade slide groove 5 and are slidably connected to the interior of the corresponding first limiting block groove 14. The two rotating threaded rods 16 are threadedly connected to the outer walls of the two end protrusions of the mounting base 19. The outer walls of the four T-shaped blocks at the upper end of the cutting blade 13 are slidably connected to the interior of the four T-shaped block grooves opened in the inner wall of the cutting blade slide groove 5. The ends of the two rotating threaded rods 16 near the limiting block 18 are threadedly extended into the interior of the second limiting block groove 17 and are rotatably connected to the outer walls of the corresponding limiting block 18.

[0034] The feeding roller 3 is rotatably connected at both ends to the opposite rear surfaces of the two support frames at the upper end of the support base 1 via rotating shafts. A first motor 2 is fixedly mounted on the upper surface of the fixed plate at the rear end of the left support frame at the upper end of the support base 1. The output end of the first motor 2 extends rotatably to the outside of the left support frame and is fixedly connected to one end of the feeding roller 3. Adjusting threaded rods 4 are rotatably connected to the slots inside the opposite surfaces of the two support frames at the upper end of the support base 1. The end of the adjusting threaded rod 4 away from the support base 1 extends rotatably to the outside of the support frame and is fixedly mounted with a rotating block. The tension roller 12 is slidably connected at both ends to the outer walls of the corresponding adjusting threaded rods 4 via connecting seats. The winding roller 10 is rotatably connected at both ends to the opposite front surfaces of the two support frames at the upper end of the support base 1 via rotating shafts. The fixed plate at the front end of the left support frame at the upper end of the support base 1... A third motor 11 is fixedly installed on the upper surface. The output end of the third motor 11 extends rotatably to the outside of the left support frame and is fixedly connected to one end of the roll roller 10. A fixed frame 7 is fixedly installed on the opposite side of the two support frames on the upper end of the support base 1. A bidirectional threaded rod 9 is rotatably connected inside the fixed frame 7. Two sliding seats 8 are threadedly connected to the outer wall of the bidirectional threaded rod 9. Two hydraulic telescopic rods 15 are fixedly installed in the groove at the lower end of the corresponding sliding seats 8. The outer walls of the T-shaped blocks on both sides of the two sliding seats 8 are slidably connected to the T-shaped block grooves opened on the inner walls of both sides of the fixed frame 7. A second motor 6 is fixedly installed on the upper surface of the middle fixed plate of the left support frame on the upper end of the support base 1. The output end of the second motor 6 extends rotatably to the inside of the fixed frame 7 and is fixedly connected to one end of the bidirectional threaded rod 9.

[0035] Furthermore, when using this device, the fabric roll is first installed on the feeding roller 3, and the first motor 2 is started. Its output end drives the feeding roller 3 to rotate, and the fabric roll is released under the rotation of the feeding roller 3. When passing the tension roller 12, the rotating blocks at both ends of the adjusting threaded rod 4 are rotated to make the adjusting threaded rod 4 rotate in the groove of the support frame, which drives the connecting seat of the tension roller 12 to move up and down, thereby adjusting the tension of the fabric roll and ensuring that the fabric roll is flatly conveyed to the cutting area. Then, when the fabric roll is conveyed to the cutting position, the second motor 6 is started. The output end of the second motor 6 drives the bidirectional threaded rod 9 to rotate in the fixed frame 7. Since the two sliding seats 8 are threadedly connected to the bidirectional threaded rod 9, and the T-shaped blocks on both sides of the sliding seats 8 slide in the T-shaped block groove of the fixed frame 7, the rotation of the bidirectional threaded rod 9 will drive the two sliding seats 8 to move closer or further apart. The distance between the two cutting blades 13 is adjusted according to the cutting requirements. After the position adjustment is completed, the output end of the hydraulic telescopic rod 15 pushes the mounting base 19 to move downward. The cutting blade 13 on the lower surface of the mounting base 19 moves down to cut the rolled fabric. Waste material from the cutting is separated during subsequent rolling. The separated rolls are collected by placing a collection box between the two support frames on the upper end of the support base 1, positioning it below the cutting blade 13. Qualified rolls are then fed to the rolling roller 10. The third motor 11 is started, and its output drives the rolling roller 10 to rotate, winding and collecting the cut fabric. If it is necessary to replace the cutting blade 13 with a different specification, rotate the two rotating threaded rods 16. The rotating threaded rods 16 rotate in the internal thread of the protrusion of the mounting base 19, causing the limiting block 18 to slide in the second limiting block groove 17, so that the limiting block 18 disengages from the first limiting block groove 14. At this time, the cutting blade 13 can be pulled out from the cutting blade slide groove 5. After replacing the new cutting blade 13, rotate the rotating threaded rods 16 in the opposite direction so that the limiting block 18 is re-engaged into the first limiting block groove 14, thus completing the replacement of the cutting blade 13.

[0036] By rotating the two rotating threaded rods 16 in the limiting assembly, the rotating threaded rods 16 rotate in the internal thread of the protrusion of the mounting base 19, causing the limiting block 18 to slide in the second limiting block groove 17, so that the limiting block 18 disengages from the first limiting block groove 14. At this time, the cutting blade 13 can be pulled out from the cutting blade slide groove 5. This makes disassembling the cutting blade 13 simple and quick, effectively improving the practicality and reliability of the equipment, while reducing the workload of the staff.

[0037] Structural Description: Support Base 1 and Feeding Assembly: Support Base 1 provides a stable support foundation for the entire device. The two support frames at the upper end are used to install components such as Feeding Roller 3, Tension Roller 12, and Rolling Roller 10. The two ends of Feeding Roller 3 are rotatably connected to the rear end of the support frame through rotating shafts and are used to place the rolled fabric raw material. The first motor 2 is fixed on the fixed plate of the left support frame to provide power for the rotation of Feeding Roller 3 and realize the automatic feeding of the rolled fabric.

[0038] Tension adjustment assembly: includes adjusting threaded rod 4 and tension roller 12. Adjusting threaded rod 4 is rotatably connected in the groove on the opposite side of the support frame. The rotating blocks at both ends are easy to adjust manually. The connecting seats at both ends of tension roller 12 are slidably connected to the outer wall of adjusting threaded rod 4. The rotation of adjusting threaded rod 4 is used to move up and down, thereby adjusting the tension of the rolled fabric and ensuring that the rolled fabric is flat and wrinkle-free when cut.

[0039] Cutting blade 13 and mounting base 19: The cutting blade 13 is used to cut the rolled fabric. The upper outer wall is slidably connected to the cutting blade slide groove 5. The first limiting block grooves 14 on both sides cooperate with the limiting blocks 18 to achieve fixation. The mounting base 19 is fixed to the output end of the hydraulic telescopic rod 15. The cutting blade slide groove 5 on the lower surface provides an installation track for the cutting blade 13. The second limiting block grooves 17 on both sides are used to install the limiting blocks 18.

[0040] Hydraulic telescopic rod 15 and sliding seat 8: The hydraulic telescopic rod 15 is fixed in the groove at the lower end of the sliding seat 8. The output end drives the mounting seat 19 and the cutting blade 13 to move up and down to realize the cutting action. The sliding seat 8 is threadedly connected to the bidirectional threaded rod 9. Under the drive of the bidirectional threaded rod 9, it slides along the T-shaped block groove of the fixed frame 7 to adjust the lateral position of the cutting blade 13 to adapt to the cutting requirements of different widths.

[0041] Rotating threaded rod 16 and limiting block 18: Rotating threaded rod 16 is threadedly connected to the protrusion of mounting base 19, and one end is rotatably connected to limiting block 18. Rotating rotating threaded rod 16 can drive limiting block 18 to slide in the second limiting block groove 17. By engaging or disengaging limiting block 18 with the first limiting block groove 14, the cutting blade 13 can be fixed or disassembled, making it convenient to replace cutting blades of different specifications.

[0042] The roll assembly: The roll roller 10 is rotatably connected to the front end of the support frame through the rotating shaft at both ends. It is used to roll the qualified roll of cloth after cutting. The third motor 11 is fixed on the fixed plate of the left support frame. The output end drives the roll roller 10 to rotate, realizing the automatic winding and collection of the roll of cloth. It works with the unloading roller 3 and the cutting assembly to form a continuous production process.

[0043] Fixed frame 7 and bidirectional threaded rod 9: Fixed frame 7 is fixed on the opposite side of two support frames, providing installation support for bidirectional threaded rod 9 and sliding seat 8. The bidirectional threaded rod 9 rotates under the drive of the second motor 6, and drives the two sliding seats 8 to move synchronously through thread transmission, ensuring that the position adjustment of the two cutting blades 13 is accurate and synchronous.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
