Description

Technical Field

[0001] The invention relates to the technical field of viscose fiber production, in particular to a steel wire cutting and taking device and method suitable for cellulose pulp bales. Background Art

[0002] Viscose fiber is made from wood pulp, cotton pulp and other polymer materials containing natural cellulose through chemical and mechanical processing. It has the characteristics of soft touch, moisture absorption and breathability, drape and flow, bright dyeing, anti-static and easy textile processing. It is a regenerated cellulose fiber derived from nature but superior to natural ones, and is one of the important raw materials for the textile industry.

[0003] In the viscose fiber production process, different chemical materials are needed, and chemical materials are generally in the form of pulp; so pulp is a very important production raw material. In order to facilitate transportation, the raw pulp is generally divided into equal small portions, and then each small portion of pulp is packaged into small rectangular blocks with cardboard, and tied with steel wire outside the cardboard. Subsequently, multiple pulp bags are combined into a large pulp bag, and the outer wall of the pulp bag is again tied with steel wire as a whole. This is convenient for transportation on the one hand, and also convenient for quantitative extraction of pulp when used. At present, when the pulp bag is transported to the processing plant, after the steel wire on the outer wall of the pulp bag is removed and cut, the steel wire outside the pulp bag cardboard needs to be removed and cut. The traditional way of removing the steel wire is to manually use wire cutters to cut the iron wire, but the existing human resources for such positions will become increasingly tight, and it is a general trend to be replaced by automation.

[0004] Patent publication number CN220721657U discloses a pulp bale shearing wire device. This patent employs a staggered structure to displace the pulp bales within the large pulp bales, separating the steel wire from the bales. A shearing mechanism then cuts the separated steel wire. However, the pulp material within the pulp bales is a single unit, and the steel wires surrounding the pulp bales consist of both transverse and longitudinal wires. The pulp bale shearing wire device described in this patent cannot separate the steel wires from the pulp bales, nor can it be used to remove the transverse wires. Therefore, the pulp bale shearing wire device described in this patent is not directly applicable to removing the steel wires from pulp bales.

[0005] The invention patent with patent publication number CN108216802B discloses a meal feeding production line for chemical fiber production, including a small bale shearing mechanism, which includes a support frame. The small bale shearing mechanism includes a support frame and a small bale wire shear. A horizontal small bale transverse guide rail is first installed on the top plate of the support frame, and then a vertical small bale longitudinal guide rail is installed on the small bale transverse guide rail. In this way, the small bale transverse guide rail and the small bale longitudinal guide rail are combined to form a two-dimensional free motion surface on the vertical plane; finally, the small bale CCD image recognition device, the small bale manipulator and the vacuum suction cup are fixed to the lower end of the small bale longitudinal guide rail; the small bale wire shear is installed on the small bale manipulator.

[0006] However, the patented small-package steel wire shear has only two-dimensional freedom and cannot be used for cutting horizontal and vertical steel wires. Secondly, the small-package steel wire shear has no wire fixing device, so the cut steel wire will directly break apart, easily causing damage to people and objects around it. Thirdly, the shooting distance of the small-package steel wire shear's CCD image recognition device is not fixed, resulting in unsatisfactory recognition results. Fourthly, the small-package steel wire shear has no distance positioning device and cannot be used for pulp packages of different specifications. Fifthly, the small-package steel wire shear has no wire recovery device, so the steel wire needs to be recovered manually, and it is not fully automatic. Therefore, the small-package steel wire shear in this patent cannot be directly used for cutting and recovering pulp packages of different specifications and packaging. Summary of the Invention

The motor base is driven to move by the telescopic rod of the sliding cylinder. The motor base slides along the guide rail to the side away from the clamping assembly. During the sliding process of the motor base, the L-shaped wire withdrawal plate pushes the steel wire rolled into a ball on the winding shaft into the steel wire collecting groove below.

[0073] A limit block 415 for limiting the movement range of the telescopic shaft of the wire fixing cylinder 411 is provided directly below the cylinder connecting member 414 . The limit block 415 is fixedly connected to the mounting plate 413 .

[0074] The wire-fixing cylinder 411 is fixedly connected to the mounting plate 413 via a connecting block 416. The connecting blocks 416 are provided in two pieces. The side surfaces of the two connecting blocks 416 are fixedly connected to the top side surfaces 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.

[0078] In this embodiment, the model of the position detection sensor 5162 is E2B-M12KN05-M1-B1; In this embodiment, step S4 specifically includes the following steps: S41. Contract the telescopic shaft of the thread-fixing cylinder 411 to move the cylinder connector 414 upward until it contacts the connecting block 416. The cylinder connector 414 drives the end of the arm I 4121 connected to the cylinder connector 414 upward. The connecting ends of the two clamping arms, arm I 4121 and arm II 4122, rotate toward each other. The thread-fixing claws 4123 of arm II 4122 rotate away from each other, opening the thread-fixing claws 4123 and simultaneously controlling the pneumatic clamp 431 to open. S42: After the position sensor 442 detects that the distance between the position detection sensor 5162 and the transverse steel wire reaches the set range, the wire fixing cylinder 411 starts to operate, and the telescopic shaft of the wire fixing cylinder 411 starts to extend; S43: The telescopic shaft of the wire-fixing cylinder 411 extends, driving the cylinder connector 414 downward until it contacts the limit block 415. The cylinder connector 414 drives the end of the arm I 4121 connected to the cylinder connector 414 downward. The other end of the arm I 4121 drives the arm II 4122 to rotate. The wire-fixing claws 4123 of the arm II 4122 of the two clamping arms clamp together, securing the wire. S44: After the steel wire is clamped and fixed, the three-axis moving mechanism 3 is actuated to lift the steel wire upward by 3-7 mm to separate the paper sheet from the steel wire, and the steel wire is lifted to the middle of the pneumatic clamp 431; S45, control the pneumatic pliers 431 to cut the transverse steel wire.

[0079] In this embodiment, the bottoms of the position detection component 44, the fixed wire component 41 and the pneumatic clamp component 43 are in the same horizontal plane, and the position detection component 44, the fixed wire component 41 and the pneumatic clamp component 43 are arranged in sequence along the width direction of the conveyor belt 21. Therefore, the distance between the position detection sensor 5162, the fixed wire component 41, the pneumatic clamp component 43 and the transverse steel wire is the same. By detecting the distance between the position sensor 442 and the transverse steel wire, the distance between the fixed wire component 41 and the transverse steel wire can be obtained.

[0080] Example 3 The difference between this embodiment and embodiment 2 is that, in this embodiment, the visual sensing mechanism 6 includes a visual sensor 61 and a fill light 62 , and the visual sensor 61 and the fill light 62 are fixedly connected to the rack 1 via a visual mounting seat 63 .

[0081] like Figure 9 As shown, the paper pressing assembly 42 includes a paper pressing cylinder 421 and a paper pressing block 422. The side of the paper pressing cylinder 421 is fixedly connected to the wire fixing assembly 41, the end of the telescopic shaft of the paper pressing cylinder 421 is fixedly connected to the paper pressing block 422, and the paper pressing cylinder 421 is fixedly connected to the wire fixing assembly 41.

[0082] The paper pressing assembly 42 also includes two optical axes 423, which are respectively arranged on both sides of the paper pressing cylinder 421 along the width direction of the conveying mechanism 2.

[0083] 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.

[0084] The cylinder guide mounting base 424 is fixedly connected to the back of the mounting plate 413 of the wire fixing assembly 41 through 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 that of embodiment 2.

[0085] In this embodiment, the visual detection sensor 5162 includes a camera and a lens. The camera model is MV-CS200-10GC, the lens model is FA1616A, and the fill light 62 model is KM-2BRD48030.

[0086] In this embodiment, step S3 includes the following steps: S31, extend the telescopic rod of the paper pressing cylinder 421 to drive the paper pressing block 422 downward; When the telescopic rod of the cardboard pressing cylinder 421 is extended, the cardboard pressing block 422 and the optical axis 423 move downward together to prevent the cardboard pressing block 422 from tilting due to uneven force during the cardboard pressing process, thereby preventing the cardboard pressing block 422 from being unable to flatten the cardboard; S32, the wire cutting mechanism 4 is moved to the horizontal wire position by the three-axis moving mechanism 3, and the telescopic rod of the paper pressing cylinder 421 is compressed and retracted; The position detection assembly 44 detects the distance between the transverse steel wire and the position sensor 442 in real time. When the position detection sensor 5162 is 3-7 mm away from the transverse steel wire, the three-axis moving mechanism 3 stops. Since the bottoms of the position detection assembly 44, the wire fixing assembly 41, and the pneumatic clamp assembly 43 are on the same horizontal plane and are arranged sequentially along the width of the conveyor belt 21, the position detection assembly 44, the wire fixing assembly 41, and the pneumatic clamp assembly 43 are at equal distances from the transverse steel wire. 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 a result, as the three-axis moving mechanism 3 moves downward, the pressure of the paper pressing block 422 on the pulp bale becomes greater and greater, thereby flattening the paper of the bale and playing a buffering role at the same time.

[0087] Example 4 The difference between this embodiment and embodiment 1 is that, in this embodiment, Figure 12-17 As shown, the wire winding mechanism 5 includes a wire winding assembly 51 for winding the wire, a clamping assembly 52 for limiting the displacement of the wire, a wire withdrawal assembly 53, and a wire winding machine base 54.

The wire clamping unit 521 and the fixing unit 522 are respectively arranged on the top surface of the winding machine base 54 near the winding shaft 512.

[0091] The rest of the structure is the same as that of Example 1.

[0095] The pressure plate roller 5213 is connected to the top surface of the winding machine base 54 through the positioning seat bracket 5216. The bottom of the positioning seat bracket 5216 is fixedly connected to the top surface of the winding machine base 54, and the top of the positioning seat bracket 5216 is rotatably connected to the pressure plate roller 5213.

[0096] The flip transmission connection assembly 5215 is a gear rack box that converts linear motion into flip motion.

[0097] The pressure plate 5211 includes a pressure plate body 5217 and a rotating shaft 5218. One end of the pressure plate body 5217 is fixedly connected to the output end of the flip transmission connection assembly 5215, and the other end of the pressure plate body 5217 extends toward the side away from the pressure plate cylinder 5212.

The pressure plate 5211 is matched with the rotating shaft 5218 and the rotatable pressure plate roller through the clearance. While being able to limit the up and down displacement of the steel wire, it can also allow the steel wire to move along the length direction of the steel wire. When the wire winding shaft 512 winds the steel wire, the steel wire will not be unable to be wound due to the limitation of the wire clamping unit 521.

[0098] like Figure 15 As shown, the fixed unit 522 includes a wire fixing plate I5221, a wire fixing plate II5222 and a fixed cylinder 5223.

[0099] A guide plate 15225 for guiding the wire path is provided on the top of the wire fixing plate 15221. The bottom of the guide plate 15225 is fixedly connected to the top of the wire fixing plate 15221. The top of the guide plate 15225 extends obliquely upward away from the winding motor 511. The rest of the structure is the same as that of embodiment 4.

[0100] In this embodiment, step S53 includes the following steps: S531, the pressing plate cylinder 5212 drives the pressing plate 5211 to flip toward the wire winding motor 511, clamping the steel wire between the pressing plate 5211 and the pressing plate roller 5213, and limiting the upward and downward displacement of the steel wire; S532. The fixing cylinder 5223 is used to drive the wire fixing plate I5221 to move toward the wire fixing plate II5222 in the channel between the two sets of wire clamping components for the fixing unit 522 to pass through, thereby clamping the steel wire between the wire fixing plate I5221 and the wire fixing plate II5222.

[0101] Example 6 The difference between this embodiment and embodiment 4 is that, in this embodiment, Figure 13 As shown, the end of the winding shaft 512 away from the motor is a Y-shaped structure 515 for clamping the steel wire.

[0102] The wire winding assembly 51 also includes a detection unit 516 for detecting the number of rotations of the wire winding shaft 512. The detection unit 516 includes a detection ring 5161 and a detection sensor 5162. The detection ring 5161 is sleeved on one end of the wire winding shaft 512 close to the wire winding motor 511, and the detection sensor 5162 is set at a position corresponding to the detection ring 5161.

[0103] As stated Figure 16 As shown, the wire withdrawal assembly 53 includes a wire withdrawal cylinder 531, an L-shaped wire withdrawal plate 532 and a wire withdrawal mounting plate 533. The wire withdrawal mounting plate 533 is arranged on the top of the wire fixing plate II 5222. The bottom of the wire withdrawal cylinder 531 is fixedly connected to the wire withdrawal mounting plate 533. The telescopic shaft of the wire withdrawal cylinder 531 is connected to one end of the L-shaped wire withdrawal plate 532, and the other end of the L-shaped wire withdrawal plate 532 extends vertically downward toward the direction close to the wire fixing plate I 5221.

[0104] A guide plate II 534 is provided on the top of the wire withdrawal plate. The bottom of the guide plate II 534 is fixedly connected to the top side of one side of the wire withdrawal plate in the vertical direction. The top of the guide plate II 534 extends obliquely upward in the direction close to the wire winding motor 511.

[0105] like Figure 17 As shown, the top surface of the winding machine base 54 is provided with a material withdrawal hole 541 forming a material withdrawal channel below the wire withdrawal plate, and the bottom of the winding machine base 54 is provided with a wire collecting groove 55 below the material withdrawal hole 541. The rest of the structure is the same as that of embodiment 4.

[0106] In this embodiment, the models of the detection ring 5161 and the detection sensor 5162 are: E3FA-RP21 / XS2F-B12PVC4A2M; In this embodiment, step S54 includes the following steps: S541, when the motor base 5141 slides along the guide rail 5143 to the side close to the clamping assembly 52, the wire winding shaft 512 passes through the middle through hole 5226 of the wire fixing plate II 5222, and the Y-shaped structure 515 at the end of the wire winding shaft 512 clamps the steel wire; S542: The wire winding motor 511 is actuated to drive the wire winding shaft 512 to rotate and reel in the steel wire; S543, the number of rotations of the winding shaft 512 is detected by the detection ring 5161 and the detection sensor 5162. When the number of rotations reaches the set number, the motor stops rotating after one wire is wound. S544: After the rotation stops, the wire withdrawing cylinder 531 is actuated to retract the telescopic rod of the wire withdrawing cylinder 531, thereby driving the L-shaped wire withdrawing plate 532 downward until the L-shaped wire withdrawing plate 532 is loosely fitted with the wire winding shaft 512; S545. The motor base 5141 is driven to move by the telescopic rod of the sliding cylinder 5145. The motor base 5141 slides along the guide rail 5143 to the side away from the clamping assembly 52. ​​During the sliding process of the motor base 5141, the L-shaped wire withdrawal plate 532 pushes the steel wire rolled into a ball on the winding shaft 512 into the steel wire collecting groove 55 below.

[0107] In this embodiment, when the sensor on the detection ring rotates to the position corresponding to the detection sensor 5162, the detection ring 5161 and the detection sensor 5162 are connected, and when the detection ring 5161 rotates to other positions, the detection ring 5161 and the detection sensor 5162 are disconnected. The detection ring 5161 and the detection sensor 5162 are connected and disconnected once, and the winding shaft rotates one circle. After the winding shaft stops rotating, the sensor on the detection ring is rotated to the position corresponding to the detection sensor 5162 through fine-tuning of the winding motor, and the detection ring 5161 and the detection sensor 5162 are connected. At this time, the Y-shaped structure state at the front end of the winding shaft corresponds to the steel wire clamped by the clamping assembly. After the steel wire is unloaded, when the sliding cylinder 5145 pushes the winding shaft to slide to the side near the clamping assembly 52, the steel wire can be stuck in the middle position of the Y-shaped structure, and the Y-shaped structure 515 at the end of the winding shaft 512 clamps the steel wire.

[0108] In this embodiment, the sliding cylinder 5145 is interlocked with the communication signal of the detection ring 5161 and the detection sensor 5162. The sliding cylinder 5145 can only move when the detection ring 5161 and the detection sensor 5162 are connected. The first function of the detection unit 516 is to detect the number of rotations of the winding shaft. When the number of rotations of the winding shaft reaches the set value, it indicates that the winding of a steel wire is completed; the second function is to position the Y-shaped structure at the end of the winding shaft. When the signals of the detection ring 5161 and the detection sensor 5162 are connected, the state of the Y-shaped structure at the front end of the winding shaft corresponds to the steel wire clamped by the clamping assembly, and the sliding cylinder 5145 can move to prevent the steel wire from being stuck in the Y-shaped structure; and after the winding shaft stops rotating, the sensor on the detection ring can be rotated to the position corresponding to the detection sensor 5162 through fine-tuning the winding motor.
