Description

Technical Field

[0001] This utility model relates to the field of viscose fiber production technology, and in particular to a wire cutting device suitable for small packages of cellulose pulp. Background Technology

[0002] Viscose fiber is made from high-molecular materials containing natural cellulose, such as wood pulp and cotton pulp, through chemical and mechanical processing. It has the characteristics of soft hand feel, moisture absorption and breathability, drape and flow, bright coloring, antistatic properties and easy textile processing. It is a regenerated cellulose fiber derived from nature but superior to nature, and is one of the important raw materials for the textile industry.

[0003] In the production of viscose fiber, various chemical materials are required, and these materials are generally in the form of pulp. Therefore, pulp is a very important raw material. To facilitate transportation, the raw pulp is usually divided into equal portions, and each portion is then packaged into small rectangular blocks using cardboard. These blocks are then bound together with wire. Multiple small pulp packages are then combined into a large pulp package, which is further bound together with wire. This facilitates transportation and allows for precise extraction of pulp during use. Currently, when the large pulp package arrives at the processing plant, after the wires on the outer wall of the large package are removed, the wires on the cardboard of the smaller pulp packages also need to be removed. Traditionally, this involves manually cutting the wires with wire cutters. However, the existing human resources for this position are becoming increasingly strained, and automation is an inevitable trend.

[0004] Utility model patent CN220721657U discloses a device for cutting steel wire from pulp bales. This patent describes a method where a staggered structure is used to misalign the smaller pulp bales, separating the steel wire from the bales. A shearing structure then cuts the separated wire. However, the pulp material inside the smaller bales is a single unit, and the steel wires outside the paperboard of the bales consist of both transverse and longitudinal wires. The device in this patent cannot separate the wire from the bales, nor is it suitable for cutting the transverse wires. Therefore, this device cannot be directly applied to cutting the steel wires from the smaller pulp bales.

[0005] Patent publication number CN108216802B discloses a feed production line for chemical fiber production, including a small package shearing mechanism. The small package shearing mechanism includes a support frame and a small package wire shear. A horizontal small package transverse slide rail is first installed on the top plate of the support frame, and then a vertical small package longitudinal slide rail is installed on the small package transverse slide rail. In this way, the small package transverse slide rail and the small package longitudinal slide rail are combined to form a two-dimensional free motion surface in the vertical plane. Finally, a small package CCD image recognition device, a small package robot, and a vacuum suction cup are fixed to the lower end of the small package longitudinal slide rail; the small package wire shear is installed on the small package robot.

[0006] However, the small-package wire cutter in this patent has several drawbacks: first, it only has two degrees of freedom, making it unsuitable for cutting horizontal and vertical wires; second, it lacks a wire-fixing device, causing the cut wire to break apart and potentially injure people or objects; third, the CCD image recognition device's shooting distance is not fixed, resulting in unsatisfactory recognition results; and fourth, it lacks a distance positioning device, making it unsuitable for different sizes of pulp packages. Therefore, the small-package wire cutter in this patent cannot be directly applied to the cutting and recycling of steel wires from pulp packages of different sizes and packaging. Summary of the Invention

The Y-axis platform 31 and X-axis platform 32 are arranged perpendicularly in the horizontal direction, and the Z-axis platform 33 is arranged vertically.

[0051] In this embodiment, those skilled in the art can set up an external controller using conventional technical means. The external controller can be a PLC controller of model 6ES7 214-1AG40-0XB0. The PLC controller is connected to the three-axis moving mechanism 3, the conveying mechanism 2, the wire cutting mechanism 4, and the vision sensing mechanism 5. The PLC controller receives the signal from the vision sensing mechanism 5 and processes the data to control the actions of the three-axis moving mechanism 3, the conveying mechanism 2, and the wire cutting mechanism 4, thereby realizing the automatic operation of the wire cutting device suitable for small packages of cellulose pulp.

[0052] In this embodiment, the cutting of the steel wire in the small packages of cellulose pulp is completed through the following steps:

[0053] S1. The pulp bales with the crisscrossing steel wires facing upwards are conveyed to the designated workstation via the conveying mechanism 2.

[0055] S3. The wire cutting mechanism 4 is moved to the position of the transverse steel wire by the action of the three-axis moving mechanism 3. During the movement, the paper pressing assembly 42 flattens the paper on both sides of the transverse steel wire.

[0056] S4. The transverse steel wire is clamped and fixed by the wire fixing assembly 41 and lifted upward, so that the cardboard is separated from the steel wire. The transverse steel wire is cut by the pneumatic clamp assembly 43.

[0057] S5. The wire fixing assembly 41 continues to fix the steel wire. The three-axis moving mechanism 3 moves the wire fixing assembly 41 to one side of the frame 1 and pulls out the cut steel wire.

[0059] S7. The pulp bales are lifted and rotated 90° by the lifting and rotating assembly 22 of the conveying mechanism 2 and then lowered. The longitudinal steel wires are adjusted to transverse steel wires. Steps S1-S5 are repeated to cut and pull out all the steel wires of the pulp bales.

[0060] Example 2

[0061] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 7 As shown, the wire-fixing assembly 41 includes a wire-fixing cylinder 411 and a clamping arm unit 412. The wire-fixing cylinder 411 is fixedly connected to the frame 1 via a mounting plate 413. The clamping arm unit 412 includes two clamping arms, which are symmetrically arranged along the length of the wire-fixing cylinder 411. The two clamping arms respectively include arm I 4121 and arm II 4122. One end of arm I 4121 is rotatably connected to the top of the telescopic shaft of the wire-fixing cylinder 411, and the other end of arm I 4121 is rotatably connected to one end of arm II 4122. The other end of arm II 4122 is a wire-fixing claw 4123 for fixing the steel wire. A connecting shaft 4124 is provided at the middle position of the two arms II 4122 along the direction of mutual approach. The two connecting shafts 4124 are rotatably connected to the mounting plate 413 via pins.

[0062] The arm I4121 is rotatably connected to the top of the telescopic shaft of the wire-fixing cylinder 411 via a cylinder connector 414. The middle position of the cylinder connector 414 is fixedly connected to the top of the telescopic shaft of the wire-fixing cylinder 411, and the two ends of the cylinder connector 414 are rotatably connected to the arms I4121 of the two clamping arms respectively.

[0063] A limiting block 415 is provided directly below the cylinder connector 414 to limit the range of motion of the telescopic shaft of the wire-fixing cylinder 411. The limiting block 415 is fixedly connected to the mounting plate 413.

[0064] The wire-fixing cylinder 411 is fixedly connected to the mounting plate 413 via a connecting block 416. Two connecting blocks 416 are provided, and the sides of the two connecting blocks 416 are fixedly connected to the top side of the mounting plate 413. A gap is provided between the two connecting blocks 416 for the telescopic shaft of the wire-fixing cylinder 411 to pass through. The wire-fixing cylinder 411 is fixedly connected to the top surface of the two connecting blocks 416, and the telescopic shaft of the wire-fixing cylinder 411 passes through the gap and is rotatably connected to the clamping arm I4121.

[0065] like Figure 8 As shown, the pneumatic clamp assembly 43 includes a pneumatic clamp 431, which is fixedly connected to the connecting block 416 and the mounting plate 413 of the wire fixing assembly 41 via a clamp mounting base 432.

[0066] like Figure 10As shown, the wire cutting mechanism 4 also includes a position detection component 44, which includes an L-shaped mounting base 441 and a position sensor 442 fixed on the L-shaped mounting base 441. The L-shaped mounting base 441 is fixedly connected to the mounting plate 413.

[0067] The bottoms of the position detection component 44, the wire fixing component 41, and the pneumatic clamp component 43 are on the same horizontal plane, and the position detection component 44, the wire fixing component 41, and the pneumatic clamp component 43 are arranged sequentially along the width direction of the conveyor belt 21. The rest of the structure is the same as in Embodiment 1.

[0068] In this embodiment, the model of the position detection sensor is E2B-M12KN05-M1-B1;

[0069] In this embodiment, step S4 specifically includes the following steps:

[0070] S41. The telescopic shaft of the wire-fixing cylinder 411 is retracted, which drives the cylinder connector 414 to move upward until it abuts against the connecting block 416. The cylinder connector 414 drives the end of arm I 4121 connected to the cylinder connector 414 to move upward. The connecting ends of the two clamping arms, arm I 4121 and arm II 4122, rotate towards each other. The wire-fixing claw 4123 of arm II 4122 rotates away from each other. The wire-fixing claw 4123 opens, and at the same time, the pneumatic clamp 431 is controlled to open.

[0071] S42, after the position sensor 442 detects that the distance between the position sensor and the transverse steel wire has reached the set range, the wire-fixing cylinder 411 starts to move, and the extension shaft of the wire-fixing cylinder 411 starts to extend.

[0072] S43, the extension shaft of the wire-fixing cylinder 411 extends, driving the cylinder connector 414 to move downward until it abuts against the limit block 415. The cylinder connector 414 drives the end of arm I 4121 connected to the cylinder connector 414 to move downward, and the other end of arm I 4121 drives arm II 4122 to rotate. The wire-fixing claws 4123 of the two clamping arms of arm II 4122 clamp together to clamp and fix the steel wire.

[0073] S44. After clamping and fixing the steel wire, the three-axis moving mechanism 3 moves the steel wire upward by 3-7mm, so that the cardboard is separated from the steel wire and the steel wire is lifted to the middle of the pneumatic clamp 431.

[0074] S45, control the pneumatic clamps 431 to cut the transverse steel wire.

[0075] In this embodiment, the bottoms of the position detection component 44, the wire fixing component 41, and the pneumatic clamp component 43 are on the same horizontal plane, and the position detection component 44, the wire fixing component 41, and the pneumatic clamp component 43 are arranged sequentially along the width direction of the conveyor belt 21. Therefore, the position detection sensor, the wire fixing component 41, the pneumatic clamp component 43 are all at the same distance from the transverse steel wire. The distance between the wire fixing component 41 and the transverse steel wire can be obtained by detecting the distance between the position sensor 442 and the transverse steel wire.

[0076] Example 3

[0077] Compared with Embodiment 2, the difference in this embodiment is that the visual sensing mechanism 5 includes a visual sensor 51 and a supplementary light 52, and the visual sensor 51 and the supplementary light 52 are fixedly connected to the frame 1 through a visual mounting base 53.

[0078] like Figure 9 As shown, the paperboard pressing assembly 42 includes a paperboard pressing cylinder 421 and a paperboard pressing block 422. The side of the paperboard pressing cylinder 421 is fixedly connected to the wire fixing assembly 41, and the end of the telescopic shaft of the paperboard pressing cylinder 421 is fixedly connected to the paperboard pressing block 422. The paperboard pressing cylinder 421 is fixedly connected to the wire fixing assembly 41.

[0079] The paper pressing assembly 42 also includes two optical shafts 423, which are respectively arranged on both sides of the paper pressing cylinder 421 along the width direction of the conveying mechanism 2. One end of the optical shaft 423 is a free end, and the other end of the optical shaft 423 is fixedly connected to the paper pressing block 422. The optical shaft 423 is fitted with a cylinder guide mounting seat 424, which slides with the optical shaft 423. The cylinder guide mounting seat 424 is fixedly connected to the paper pressing cylinder 421.

[0080] The free end of the optical axis 423 is provided with a sealing plate 425 to prevent the cylinder guide mounting seat 424 from sliding out.

[0081] The cylinder guide mounting base 424 is fixedly connected to the back of the mounting plate 413 of the wire fixing assembly 41 via a transition plate 426, and the paper pressing cylinder 421 is fixedly connected to the cylinder guide mounting base 424. The rest of the structure is the same as in Embodiment 2.

[0082] In this embodiment, the visual inspection sensor includes a camera and a lens. The camera model is MV-CS200-10GC, the lens model is FA1616A, and the fill light 52 model is KM-2BRD48030.

[0083] In this embodiment, as Figure 11As shown, the vision mounting base 53 is a rectangular structure. A vision mounting frame is set at the center of the rectangular structure. The top of the vision mounting frame is fixedly connected to the frame 1 by bolts, and the bottom of the vision mounting frame is fixedly connected to the vision sensor 51. The supplementary light 52 is set at the bottom of the rectangular structure.

[0084] In this embodiment, step S3 includes the following steps:

[0085] S31. Extend the telescopic rod of the paper-pressing cylinder 421 to drive the paper-pressing block 422 to move downward;

[0086] During the extension of the telescopic rod of the paper-pressing cylinder 421, the paper-pressing block 422 and the optical shaft 423 move downward together to prevent the paper-pressing block 422 from tilting due to uneven force during the process of pressing the paper flat, thus preventing the paper flattening from being unable to be flattened.

[0087] S32. The wire cutting mechanism 4 is moved to the position of the transverse steel wire by the action of the three-axis moving mechanism 3, and the telescopic rod of the compression paper pressing cylinder 421 is retracted at the same time.

[0088] The distance between the transverse steel wire and the position sensor 442 is detected in real time by the position detection component 44. When the position detection sensor is 3-7mm away from the transverse steel wire, the three-axis moving mechanism 3 stops moving. Since the bottoms of the position detection component 44, the wire fixing component 41 and the pneumatic clamping component 43 are on the same horizontal plane, and the position detection component 44, the wire fixing component 41 and the pneumatic clamping component 43 are arranged sequentially along the width direction of the conveyor belt 21, the distances between the position detection component 44, the wire fixing component 41 and the pneumatic clamping component 43 and the transverse steel wire are equal.

[0089] During the downward movement of the three-axis moving mechanism 3, the paper-pressing cylinder 421 is compressed by the three-axis moving mechanism 3. As the three-axis moving mechanism 3 moves downward, the pressure of the paper-pressing block 422 on the pulp bales increases, thereby flattening the paper of the bales while providing a buffering effect.

[0090] In this embodiment, the paperboard pressing mechanism achieves flatness on both sides of the steel wire, while reducing the vibration of the entire mechanism when the wire cutting mechanism moves towards the steel wire.

[0091] In this invention, "rotational connection" refers to a connection method that allows two or more connected components to rotate relative to each other around a certain axis. "Sliding fit" refers to a fit relationship in which two contacting parts can slide relative to each other after assembly.

[0092] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
