Description

Technical Field

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention achieves webbing winding by setting up a labeling component, using a first motor to drive a second hexagonal rod to rotate a winding wheel, and simultaneously utilizing the webbing's contact with a friction chuck with anti-slip teeth to effectively prevent slippage during conveying, ensuring the stability and accuracy of webbing conveying. The linkage crossbar, driven by the fifth support rod through the first auxiliary rotating shaft, undergoes complex movement and rotation. During the movement, the insertion shaft slides within the embedded groove and moves along a specific trajectory according to the shape of the guide auxiliary plate, cyclically moving from above the guide auxiliary plate to the upper surface, then to the lower surface, and finally back to the upper surface. This allows the linkage crossbar to rotate regularly around the first auxiliary rotating shaft, enabling precise control of the position and posture changes of the linkage crossbar.

[0021] When the linkage crossbar is in a horizontal state, the rubber baffle moves along with the ring and the webbing, causing the adhesive in the dispensing cone to flow onto the webbing. The flow is restricted by the ring, ensuring that there is an appropriate amount of adhesive for attaching the label while preventing the adhesive from flowing freely and contaminating the equipment and webbing. At this time, the label falls precisely at the position where the adhesive was previously applied to the webbing, allowing the label to adhere to the adhesive on the webbing and thus labeling the webbing. As the webbing moves, the labeling cylinder and the dispensing cone move synchronously to press the newly adhered label, effectively improving the labeling quality, reducing the occurrence of label detachment and other defects, improving the automatic labeling effect, and increasing the efficiency of webbing labeling.

[0022] 2. This invention, by incorporating a tensioning component, addresses the issue of significant resistance exerted by the friction plate and frame-shaped counterweights on the rotating friction disc as the webbing winds around the take-up reel, requiring the overcoming of this resistance to continue. This resistance effectively tightens the webbing, preventing slackness, wrinkles, or twisting during transport and labeling. Maintaining tautness is crucial for accurate labeling, ensuring that labels are accurately placed in their designated positions with superior flatness and adhesion.

[0023] 3. This invention, by setting up a detection component, converts the presence or absence of a label into a change in the contact state between the top crossbar and the touch switch, thereby controlling the on / off state of the warning light. When a label passes by, the top crossbar is lifted, the touch switch is not pressed, and the warning light stops lighting up; when there is no label, the bending rod, under the action of the first counterweight and other components, presses down on the top crossbar, causing the top crossbar to press the touch switch, and the warning light lights up. In this way, the physical state of the label on the webbing is transformed into an intuitive visual signal, allowing operators to quickly understand the labeling status of the webbing from a distance, achieving a simple and effective signal transmission function.

[0058] Work steps

[0059] Before using the labeling machine, the unwinding roller 542, with the webbing wound around it, is fitted onto the first hexagonal bar 56, and the take-up roller 543 is fitted onto the second hexagonal bar 541. One end of the webbing on the surface of the unwinding roller 542 is pulled, causing the webbing to pass through the interior of the U-shaped clamp 58, around the surface of the auxiliary pulley 512, and then pass under the friction chuck 520, positioned between the first rotating disk 519 and the second rotating disk 521. One end of the webbing is then fixedly connected to the surface of the take-up roller 543. The adhesive used to bond the label 536 is poured into the dispensing cone 524, and multiple labels 536 are placed inside the labeling cylinder 526. Then, the pressure plate 534 is inserted into the labeling cylinder 526 to squeeze the label 536. Under the constraint of the shape and gravity of the isosceles trapezoidal pressure block 535, the bottom label 536 slides into the square groove 537. Then, the labeling machine is connected to an external power source, and the first motor 540 can be started by operating the external controller.

[0060] When the labeling machine is in use, the operation of the first motor 540 drives the second hexagonal rod 541 to rotate, which in turn drives the take-up roller 543 to rotate, causing the webbing to wrap around the surface of the take-up roller 543. During the wrapping process, the webbing and the surface of the friction chuck 520 are in contact, and the surface of the friction chuck 520 has anti-slip teeth to prevent the webbing from slipping on the surface of the friction chuck 520. When the webbing is wrapped around the surface of the take-up roller 543, it drives the friction chuck 520 to rotate. The rotation of the friction chuck 520 drives the first rotating disk 519 and the first connecting shaft 517 to rotate synchronously. The first connecting shaft 517 is inserted into the hollow slide groove 518, which causes the fifth support rod 516 to move horizontally back and forth. During the movement, the fifth support rod 516 passes through... The first auxiliary rotating shaft 538 drives the linkage crossbar 547 to move synchronously. When the linkage crossbar 547 moves, it drives the insertion shaft 549 to slide inside the embedding groove 510 via the bottom rod 548. That is, when the linkage crossbar 547 drives the second counterweight 546 to move towards the L-shaped plate 51, the insertion shaft 549 adheres to the inner wall of the square guide plate 59 and slides above the guide auxiliary plate 511. After moving a certain distance, the insertion shaft 549 begins to slide against the upper surface of the guide auxiliary plate 511. Furthermore, due to the constraints of the arc-shaped groove on one side of the guide auxiliary plate 511 and the shape of the embedding groove 510, the insertion shaft 549 moves to the side of the guide auxiliary plate 511 closer to the L-shaped plate 51. Since the first counterweight 52 can only move vertically, it continues to move... The linkage crossbar 547 drives the second counterweight 546 to move synchronously, causing the auxiliary cone 525 to slide on the surface of the linkage crossbar 547. During this process, the position between the second counterweight 546 and the linkage crossbar 547 remains unchanged, reducing the lever arm of the linkage crossbar 547 near the auxiliary cone 525. When the insertion shaft 549 moves to the position of the arc-shaped groove on one side of the guide auxiliary plate 511, the second counterweight 546's gravity causes the insertion shaft 549 to move downwards to below the guide auxiliary plate 511. During this process, the linkage crossbar 547 rotates around the first auxiliary rotating shaft 538, and the fifth support rod 516 begins to move away from the L-shaped plate 51, causing the insertion shaft 549 to slide on the guide auxiliary plate 511. The bottom surface of plate 511 slides, and during the sliding process, the torque applied by the first counterweight 52 to the linkage crossbar 547 gradually increases, which causes the insertion shaft 549 to move a distance below the guide auxiliary plate 511 and then begin to slide against the bottom surface of the guide auxiliary plate 511. When the insertion shaft 549 slides out from the bottom surface of the guide auxiliary plate 511, it can slide upward along the side of the guide auxiliary plate 511 away from the L-shaped plate 51. Since the gap between the side of the guide auxiliary plate 511 away from the L-shaped plate 51 and the square guide plate 59 is large, it will not cause the fifth support rod 516 to get stuck. The insertion shaft 549 moves upward to the top of the guide auxiliary plate 511, thereby causing the linkage crossbar 547 to perform the above operation in a cycle.

[0061] When the webbing is wound onto the take-up reel 543, the webbing on the upper surface of the worktable 3 slides against the surface of the worktable 3. When the linkage crossbar 547 is in a horizontal state, the ring 527 and the webbing on the upper surface of the worktable 3 are in contact. Under the action of the shape of the isosceles trapezoidal pressure block 535 and gravity, the lower label 536 is made to adhere to the surface of the webbing. At this time, the lowermost label 536 falls exactly onto the adhesive on the webbing. As the webbing moves, the labeling cylinder 526 and the adhesive cone 524 move synchronously with the webbing, pressing the label 536 that has just been adhered to the webbing, ensuring the adhesion effect between the square groove 537 and the webbing. When the ring 527 adheres to the webbing, the rubber stop is driven by the slide bar 531. As the disc 528 moves upward, the adhesive inside the dispensing cone 524 flows along the inside of the feeding hole 529 onto the webbing. The flow range of the adhesive is restricted by the ring 527. When the linkage crossbar 547 begins to tilt, it drives the dispensing cone 524 and the labeling cylinder 526 to move upward. As the fifth support rod 516 drives the linkage crossbar 547 to move away from the L-shaped plate 51, the webbing continues to slide on the surface of the workbench 3. When the linkage crossbar 547 begins to move horizontally, it drives the labeling cylinder 526 and the dispensing cone 524 to move synchronously until the label 536 at the bottom of the labeling cylinder 526 falls precisely at the dispensing position of the dispensing cone 524 on the webbing.

[0062] The first motor 540 drives the second hexagonal rod 541, which in turn rotates the winding wheel 543 to achieve webbing winding. At the same time, the webbing is in contact with the friction chuck 520 with anti-slip teeth, which effectively avoids the webbing slippage during the conveying process and ensures the stability and accuracy of the webbing conveying. The linkage crossbar 547 moves and rotates in a complex manner under the drive of the fifth support rod 516 through the first auxiliary rotating shaft 538. During the movement, the insertion shaft 549 slides in the embedding groove 510 and moves along a specific trajectory according to the shape of the guide auxiliary plate 511. The cyclic movement from above the guide auxiliary plate 511 to the upper surface, then to the lower surface, and finally back to the upper surface makes the linkage crossbar 547 rotate regularly around the first auxiliary rotating shaft 538 as the axis. It can accurately control the position and posture changes of the linkage crossbar 547, thereby accurately adjusting the timing and force of the operation related to the webbing and the label 536.

[0063] When the linkage crossbar 547 is in a horizontal state, the rubber baffle 528 is moved by the ring 527 adhering to the webbing and the slide bar 531, so that the adhesive in the dispensing cone 524 flows to the webbing and the flow range is restricted by the ring 527. This ensures that there is an appropriate amount of adhesive for pasting the label 536, while preventing the adhesive from flowing indiscriminately and contaminating the equipment and webbing. At this time, the label 536 is exactly placed at the position where the adhesive was last applied to the webbing, so that the label 536 is adhered to the adhesive on the webbing, thus achieving labeling of the webbing. As the webbing moves, the labeling cylinder 526 and the dispensing cone 524 move synchronously to press the newly adhered label 536, which effectively improves the labeling quality and reduces the occurrence of defects such as the label 536 falling off.

[0064] When the webbing is wound on the take-up wheel 543, the unwind wheel 542 drives the first hexagonal rod 56 to rotate, which in turn causes the friction disc 67 to rotate. The friction plate 61 and the friction disc 67 are in contact, and the force between the friction plate 61 and the friction disc 67 is increased under the action of the weight of the frame-shaped counterweight 62, which in turn increases the resistance during the rotation of the first hexagonal rod 56, thereby achieving the effect of tightening the webbing.

[0065] As the webbing winds around the take-up reel 543 and drives a series of components, the friction disc 67 rotates under significant resistance from the friction plate 61 and the frame-shaped counterweight 62. This makes the winding process of the webbing on the take-up reel 543 no longer easy and free, but requires overcoming this resistance to continue. This resistance effectively tightens the webbing, preventing slackness, wrinkles, or twisting during transport and labeling. Maintaining the webbing's tautness is crucial for subsequent precise labeling operations, because only when the webbing is flat and stable can the label 536 be accurately pasted in the predetermined position, and the flatness and firmness of the pasting can be better guaranteed, improving the automatic labeling effect and increasing the efficiency of webbing labeling.

[0066] When the webbing moves the label 536 pasted on its surface, due to the thickness of the label 536, as it passes under the roller 76, the inclined guide rod 74 drives the second auxiliary shaft 72 to rotate. After the rectangular sleeve 79 passes the label 536, the inclined guide rod 74 rotates back to its original position, thereby driving the gear 73 to rotate and return. The rotation of the gear 73 drives the rack 78 to move vertically back and forth. When the rack 78 moves upward, it pushes up the top crossbar 710, so that the top crossbar 710 is no longer pressing the touch switch 711. Under the action of the elastic potential energy of the spring 715, the built-in resistance plate 716 squeezes the rectangular sleeve 79, thereby allowing the built-in insert rod 714 to move. The position is fixed after the top crossbar 710 is moved. When the top crossbar 710 is not pressed by the touch switch 711, the warning light 718 stops lighting. When the first counterweight 52 moves down and drives the bending rod 713 down through the longitudinal insert plate 53, the end of the bending rod 713 presses the top crossbar 710, causing the top crossbar 710 to move down and press the touch switch 711, so that the warning light 718 continues to light up. In this way, the warning light 718 lights up intermittently. By observing the status of the warning light 718, the status of the webbing label can be judged. When the warning light 718 is continuously lit without flashing, it means that no label 536 was applied during the current webbing conveying process, and manual labeling is required.

[0067] The presence or absence of a label is converted into a change in the contact state between the top horizontal bar 710 and the touch switch 711, which in turn controls the illumination of the warning light 718. When a label passes by, the top horizontal bar 710 is lifted, the touch switch 711 is not pressed, and the warning light 718 stops illuminating. When there is no label, the bending rod 713 presses down on the top horizontal bar 710 under the action of the first counterweight 52 and other components, causing the top horizontal bar 710 to press the touch switch 711, and the warning light 718 illuminates. In this way, the physical state of the label on the webbing is transformed into an intuitive visual signal, allowing operators to quickly understand the labeling status of the webbing from a distance, thus achieving a simple and effective signal transmission function.

[0068] Example 2: Figure 1 As shown, this embodiment provides a webbing production line, including a dyeing oven, a receiving box, a visual inspection mechanism, and a winding mechanism. After dyeing, the webbing enters the dyeing oven for drying, then enters the receiving box, and is then inspected by the visual inspection mechanism. Finally, the winding mechanism winds up the webbing, completing the production of the webbing.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
