Description

Technical Field

[0001] This utility model relates to the technical field of material strip processing equipment, and in particular to an ultrasonic automatic slitting machine. Background Technology

[0002] Ultrasonic slitting machines are suitable for cutting and slitting fabrics such as webbing and label tapes. They can process materials such as polyester, nylon, cotton, synthetic fabrics, and natural rubber yarn. The material strip is cut into the desired shape by the ultrasonic slitting machine, generating waste material. In existing technology, the cut material strip needs to be manually collected, separating the desired finished product from the waste material and placing them onto different cores for subsequent sewing. This manual collection operation is inconvenient, severely impacting production efficiency and increasing production costs for enterprises.

[0003] In existing technologies, slitting machines use a direct feeding method. The feed roll, which winds the material strip, directly passes the strip through the slitting machine's worktable. There is no drive mechanism on the feed roll to control unwinding; the slitting machine alone drives the strip, which in turn causes the feed roll to unwind, increasing the load on the slitting machine's motor. Furthermore, there is no tensioning mechanism between the slitting machine and the feed roll to control tension. The slitting speed directly affects the state of the strip, causing it to accumulate or tear. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] refer to Figures 1-12 An ultrasonic automatic slitting machine includes a frame 24, a feeding mechanism 1 mounted on the frame 24, and a slitting machine 3 mounted on a workbench 2 that can cut a strip 25 into waste material 2501 and finished material 2502. A feeding tensioning mechanism 4 for controlling the tension of the strip 25 is provided between the feeding mechanism 1 and the slitting machine 3. The frame 24 is also provided with a waste material winding device 5 for winding up waste material and a finished material winding device 6 for winding up finished material.

[0019] The feeding mechanism 1 includes a strip unwinding roller 101 for feeding material, a fourth drive structure 102 for driving the strip unwinding roller 101 to rotate and unwind, and a sliding structure 26 for driving the strip unwinding roller 101 and the fourth drive structure 102 to slide axially. The feeding tensioning mechanism 4 includes at least one feeding swing rod 401, or a combination of at least one feeding swing rod 401 and at least one feeding tensioning rod 402. The feeding swing rod 401 is equipped with a detector that can detect the rotation amplitude, and the unwinding speed is controlled according to the feedback from the detector. The feeding swing rod 401 can swing along with the material conveying as the material conveys. If the swing amplitude is too large and exceeds the set range, the detector can detect and provide feedback to the feeding mechanism 4, so that the feeding mechanism 4 can control the unwinding speed to ensure that the material conveying maintains reasonable tension.

[0020] In this embodiment, the feeding tensioning mechanism 4 includes a feeding swing arm 401 and four feeding tensioning arms 402, namely: a first feeding tensioning arm 4021, a second feeding tensioning arm 4022, and a third feeding tensioning arm 4023 located between the feeding mechanism 1 and the slitting machine 3; and a fourth feeding tensioning arm 4024 located below the worktable. The feeding swing arm 401 is located between the second feeding tensioning arm 4022 and the third feeding tensioning arm 4023. Figure 3 The material belt passes from the lower end of the first feeding tension rod 4021 to the upper end of the second feeding tension rod 4022, then passes the lower end of the feeding swing rod 401 to the upper end of the third feeding tension rod 4023, and finally passes the lower end of the fourth feeding tension rod 4024 before being transported into the slitting machine. The four feeding tension rods are either rotatable or have smooth surfaces, allowing for smoother material belt movement.

[0021] The fourth drive structure 102 includes a fourth drive motor 1021 and a motor mounting bracket 1022. The strip unwinding roller 101 is mounted on the motor mounting bracket 1022 via an unwinding roller mounting shaft 39. A fourth synchronous belt assembly 38 is provided between the unwinding roller mounting shaft 39 and the fourth drive motor 1021. The fourth drive motor 1021 drives the unwinding roller mounting shaft 39 to rotate via the fourth synchronous belt assembly 38, thereby driving the strip unwinding roller 101 to rotate and unwind.

[0022] The sliding structure 26 includes a sliding seat 2601 mounted on the frame 24 and a screw 2602 mounted on the sliding seat 2601. A nut slider 2603 is mounted on the screw 2602. A manual rotating wheel 27 is provided at one end of the sliding seat 2601 to drive the screw 2602 to rotate and move the nut slider. The motor mounting bracket 4022 is mounted on the nut slider 2603. Rotating the manual rotating wheel 27 drives the nut slider to slide, which in turn drives the entire motor mounting bracket 1022, including the drive structure and the strip unwinding roller 101, to slide together. This allows adjustment of the strip position so that the strip can accurately enter the working position of the slitting machine. Preferably, the worktable 2 has a pressure plate 44 for pressing the strip on the side near the input end of the slitting machine. The strip 25 is transported from the pressure plate 44 and the worktable 2 into the slitting machine for slitting.

[0023] A feeding tensioning mechanism is set between the slitting machine and the feeding mechanism to ensure that the material belt maintains a reasonable tension during conveying. The unwinding speed of the feeding mechanism is adjusted in a timely manner according to the feedback from the feeding swing arm 401. After entering the slitting machine, the cutting effect is better, and it is less likely to cause material belt accumulation or excessively loose or tight conditions. The conveying is smooth, which facilitates subsequent winding.

[0024] The waste material winding device 5 includes a waste material winding roller 501, a first drive structure 502 for driving the waste material winding roller 501 to rotate, a waste material guide 7, a waste material conveying mechanism 8, and a first tensioning mechanism 9 for controlling the tension of the waste material. The first drive structure 502 includes a first drive motor 5021 and a first synchronous belt assembly 5022 disposed between the waste material winding roller and the first drive motor. The first drive motor 5021 drives the waste material winding roller 501 to rotate through the first synchronous belt assembly 5022.

[0025] The waste guide 7 includes a guide mounting frame 702, on which at least one rotatable rotating block 703 is provided. Each rotating block 703 has a waste material feed hole 701. The waste guide 7 is equipped with a sensor that can sense the rotation range of the rotating block 703 to determine whether the tape has broken. The waste guide 7 is located between the slitting machine 3 and the waste material conveying mechanism 8. A winding hole 23 is also provided near the waste material take-up roller 501. Preferably, the waste guide 7 includes several waste material feed holes 701 arranged side by side for threading multiple strips of waste material, allowing multiple strips of waste material to be wound simultaneously for higher efficiency. Initially, the rotating block 703 hangs naturally under the action of gravity. When the waste material passes through the waste material feed hole 701, it will lift the rotating block 703. If the waste material breaks, the rotating block 703 will return to its hanging state and be detected by the sensor, causing the entire machine to stop operating. This allows for timely handling of belt breakage, preventing the accumulation of waste material due to continued operation after belt breakage.

[0026] The finished material winding device 6 includes at least one finished material winding mechanism 10, a finished material conveying mechanism 11, and a second tensioning mechanism 12 for controlling the tension of all finished materials. The finished material winding mechanism 10 has at least one row, with at least one mechanism in each row. The finished material winding mechanism 10 includes a finished material winding roller 1001, a guide wheel assembly 1002 that can reciprocate along the axial direction of the finished material winding roller 1001, and a pressure roller assembly 1003 for pressing the material, which is located close to the finished material winding roller 1001. The finished material winding mechanism 10 also includes a third tensioning mechanism 16 for controlling the tension of a single finished material.

[0027] In this embodiment, the finished material winding mechanism 10 has two rows, with four in each row, and each row has at least one transfer wheel 40 for transferring the finished material. Preferably, each finished material winding mechanism has one transfer wheel 40. Setting up multiple finished material winding mechanisms 10 allows multiple finished materials to be wound up simultaneously, resulting in higher efficiency. The transfer wheel 40 is used to separately wind multiple finished materials onto different finished material winding rollers 1001, enabling multiple finished materials to be wound up simultaneously. The transfer wheel 40 also serves to support the transportation of finished materials and prevent mutual interference.

[0028] The guide wheel assembly 1002 includes a guide wheel 18, a guide wheel seat 19, and a guide wheel mounting rod 20. Because the finished material take-up roller is very long, the reciprocating motion of the guide wheel assembly 1002 is to ensure that the finished material is evenly wound onto the finished material take-up roller 1001, and this allows more finished material to be stored on the finished material take-up roller 801. The pressure roller assembly 1003 includes a pressure roller 21 and a pressure roller mounting frame 22. The pressure roller mounting frame 22 is rotatably mounted on the housing 13. The pressure roller 21 presses the finished material on the finished material take-up roller 1001 by gravity and / or elasticity. The pressure roller 8031 ​​is used to press the finished material on the finished material take-up roller 801, allowing the finished material to be wound more tightly and in greater quantities.

[0029] The upper end of the frame 24 is provided with a second drive structure 14 for driving the finished material take-up roller 1001 to rotate and a third drive structure 15 for driving the guide wheel assembly to reciprocate.

[0030] The second drive structure 14 includes a second drive motor 1401, a gear 1402 driven by the second drive motor 1401, and a rack 1403 cooperating with the gear 1402. The third drive structure 15 includes a third drive motor 1501 and a finished material take-up roller mounting frame 1502. The second and third drive motors are mounted on the same motor mounting plate 28. The rack 1403 is mounted in the axial direction of the finished material take-up roller and is connected to the guide wheel assembly 1002 via a connecting plate 29. A guide rail assembly 30 is also provided between the connecting plate 29 and the motor mounting plate 28. The second drive motor 1401 drives the gear 1402 to rotate, and the gear cooperates with the rack to drive the rack 1403 to move, thereby moving the entire connecting plate 29, including the guide wheel assembly 1002 on the connecting plate 29.

[0031] The first tensioning mechanism 9 includes at least one first swing arm 901, or a combination of at least one first swing arm 901 and at least one first tensioning rod 902; the second tensioning mechanism 12 includes at least one third swing arm 1201, or a combination of at least one second swing arm 1201 and at least one second tensioning rod 1202; the third tensioning mechanism 16 includes at least one third swing arm 1601, or a combination of at least one third swing arm 1601 and at least one third tensioning rod 1602. The first, second, and third swing arms can all swing to control the tension of the waste or finished material. Each of the three swing arms is equipped with a detector capable of detecting the swing angle of the corresponding swing arm and providing feedback to maintain reasonable tension in the waste and finished materials, preventing the swing arms from being stretched to their limits and also preventing material breakage or accumulation. The first swing arm controls the tension of the waste material, thereby controlling the unwinding speed of the feeding mechanism 1 and the slitting speed of the slitting machine 3; the second swing arm controls the tension of all finished materials located on the first tensioning rod, thereby controlling the unwinding speed of the feeding mechanism 1 and the slitting speed of the slitting machine 3; the third swing arm controls the tension of a single sliver of finished material located on the corresponding finished material take-up roller, thereby controlling the take-up speed of the finished material take-up roller.

[0032] For example Figure 10 This is an embodiment of the first tensioning mechanism, which includes a first rocker arm, a first tensioning rod, and a fixed hook 42 located near the waste take-up roller and movable along the axial direction of the waste take-up roller. Waste material is conveyed from the waste conveying mechanism to the lower end of the first rocker arm, then wound around the top of the first tensioning rod, and then wound onto the waste take-up roller via the fixed hook 42.

[0033] The finished material conveying mechanism 11 of the finished material winding device and the waste material conveying mechanism 8 of the waste material winding device are mounted on the same mounting frame 17. The finished material conveying mechanism 11 includes a first driving wheel 1101 and a first driven wheel 1102 that cooperate with each other. A first adjustment structure 1103 that can adjust the height of the first driven wheel 1102 is provided between the first driven wheel 1102 and the mounting frame 17. The waste material conveying mechanism 8 includes a second driving wheel 801 and a second driven wheel 802 that cooperate with each other. A second adjustment structure 803 that can adjust the height of the second driven wheel 802 is provided between the second driven wheel 802 and the mounting frame 17.

[0034] The mounting bracket 17 is also equipped with a fifth drive structure 41 for driving the first and second drive wheels to rotate. The fifth drive structure 41 includes a fifth drive motor 4101, which directly drives either the first or second drive wheel. A fifth synchronous belt assembly 4102 (not shown) is provided between the first and second drive wheels. Regardless of whether the fifth drive motor 4101 drives the first or second drive wheel, the two drive wheels can rotate simultaneously for feeding under the transmission of the fifth synchronous belt assembly. Finished material passes between the first and second drive wheels, while waste material passes between the second drive wheel and the second driven wheel.

[0035] The first and second adjustment structures are identical, each including an adjustment handle 31. The mounting frame 17 has mounting slots 32 for mounting the first and second driven wheels. The first and second driven wheels are both mounted on a mounting shaft 33, with the corresponding mounting shafts 33 located in the corresponding mounting slots 32. The mounting frame 17 also has an adjustment plate 34 located at the corresponding position of the mounting slots 32. The adjustment plate 34 has a vertical shaft 3402 in its adjustment slot 3401. The mounting shaft 33 has a hole that mates with the vertical shaft, allowing the mounting shaft to slide up and down along the vertical shaft 3402. The vertical shaft 3402 is equipped with a spring 35 above the mounting shaft 33. The adjustment plate 34 has a waist-shaped groove 36 and an adjustment bolt (not shown in the figure) located in the waist-shaped groove. The position of the adjustment plate 34 can be adjusted up and down to adjust the stroke of the mounting shaft 33. The adjusting handle 31 has a U-shaped groove at one end that engages with the mounting shaft 33, and a pull rod at the other end for easy manual operation. A limiting post 43 for limiting the position is located at the lower end of the adjusting handle 31. A fixing bolt (not shown in the figure) and a fixing bolt mounting hole 37 are provided between the adjusting plate and the mounting frame 13 to fix the adjusting handle 31 after adjustment. Before threading the tape, the pull rod can be manually pressed downwards, engaging with the mounting shaft 33 through the U-shaped groove to raise the first or second driven wheel for easier tape threading. Then, the fixing bolt is pressed against the side wall of the adjusting handle 31 for fixation. The lifting distance of the driven wheel can also be adjusted according to the thickness of the finished material.

[0036] The specific workflow is as follows: The feeding mechanism provides the material strip, which enters the working position of the slitting machine through the feeding tensioning mechanism. The slitting machine cuts the material strip into waste material and finished material. The waste material and finished material are manually separated. The waste material passes through the waste material guide and then passes between the second driving wheel and the second driven wheel of the waste material conveying mechanism. It is wound through the first tensioning mechanism and finally all the waste material is wound onto the waste material take-up roller through the waste material belt hole. The waste material take-up roller and the waste material conveying mechanism are activated to automatically transport and take up the waste material. All the finished material first passes through the finished material conveying mechanism and is wound around the second tensioning mechanism. Then, each piece of finished material is wound onto the corresponding third tensioning mechanism and the finished material take-up roller. The finished material conveying mechanism and the finished material take-up roller are activated to automatically transport and take up the finished material.

[0037] This invention employs an automated method for winding up finished and waste materials, which is simple to operate, saves manpower and time, and is more efficient.
