Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubberizing equipment, in particular to a sealing strip rubberizing device. BACKGROUND

[0002] Sealing strips are products that seal something, making it difficult to open, and play the roles of shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials such as rubber, paper, metal, and plastic. Since the 1980s, sealing strips have been applied to various industries such as automobiles, doors and windows, cabinets, refrigerators, and containers. According to the requirements of different industries, unique automobile sealing strips, mechanical sealing strips, and door and window sealing strips have been developed. When applying adhesive tape to sealing strips, sealing strip adhesive tape equipment is needed to process it.

[0003] The existing sealing strip rubberizing equipment generally has low automation, relies on manual operation, and has low production efficiency and inconsistent product quality. Its movement function is simple, and it is difficult to complete precise attachment of curves or special-shaped contours, limiting its application range. The pressing mechanism is designed rigidly, lacks elastic compensation, and is prone to uneven pressing, blistering, and debonding. Moreover, the changeover adjustment is complicated, the winding system is designed with a single disc, and the replacement requires stopping production. The winding is not uniform, affecting the subsequent process. The surface of the key components is prone to glue sticking, requiring frequent shutdown for cleaning and maintenance, which not only affects production stability but also increases operating costs. These defects seriously restrict the efficient and high-quality production of sealing strip products. Therefore, we propose a sealing strip rubberizing device to solve this problem. SUMMARY

[0022] 1. In the present application, the device is highly integrated and automatically designed, and multiple traditional processes such as feeding, rubberizing, pressing, cutting and winding, which need to be carried out step by step and manually intervened, are seamlessly connected into a continuous automatic process. Through unified programming control of the central control cabinet, various execution elements such as motors and hydraulic cylinders can accurately cooperate to realize the whole-process unmanned operation from the start of the sealing strip feeding to the completion of the finished product winding. This integrated design completely eliminates the conversion downtime between processes and the speed bottleneck caused by manual operation, greatly improves the production efficiency, and ensures the consistency and stability of the final product quality by automatically controlling the process parameters such as rubberizing pressure, traction speed and cutting length, which avoids the inevitable fatigue errors in manual operation.

[0050] Preparation stage and feeding

[0051] Sealing strip feeding: Install the rolled sealing strip to be glued onto the feeding roller 402 of the sealing strip feeding assembly 4, and fix it through the end disc 403 and the tightening bolt 404. Pull out the head end of the sealing strip and guide it through the feeding groove 3 to the pad 2 area on the upper end of the workbench 1.

[0052] Glue strip feeding: Install the rolled glue strip on the glue strip reel 525 of the glue sticking assembly 5, pull out the head of the glue strip, and pass through the two glue guide rollers 526, the glue guide wheel 521, and the through hole of the cutting box 517 in sequence. Finally, the glue strip is clamped and fixed by the clamping jaw 533 of the glue clamping box 530. The surface of the glue guide roller 526 and the glue guide wheel 521 is coated with an anti-adhesion coating to ensure smooth delivery of the glue strip without adhesion.

[0053] Glue sticking process

[0054] Initial positioning: Start the control cabinet 10, the first motor 505 drives the first lead screw 504 to rotate, driving the vertical plate 507 and all components on it to move along the X-axis first sliding rail 503 direction. The second motor 511 drives the second lead screw 510 to rotate, driving the lifting plate 513 to move along the Y-axis second sliding rail 509 direction. Move the glue clamping box 530 and the pressing wheel 523 to the initial glue sticking position of the sealing strip.

[0055] Glue strip traction and sticking:

[0056] Clamping traction: the third motor 536 in the clamping box 530 is started, driving the threaded rod 531 to rotate, as the two ends of the threaded rod 531 are reverse threaded, driving the two moving sleeves 532 and the clamping jaw 533 to move towards each other, firmly clamping the head end of the adhesive tape.

[0057] Coordinated movement: the rubber roller motor 516 drives the clamping roller 515 to rotate, assisting in conveying the adhesive tape. When the device starts to work, the clamping box 530 moves along the path required by the sealing strip under the overall drive of the adhesive application assembly 5.

[0058] Pressing and pasting: during the movement, the second hydraulic cylinder 522 pushes the pressing wheel 523 to press down, tightly rolling and pasting the adhesive tape pulled out of the clamping jaw 533 on the surface of the sealing strip. The surface of the pressing wheel 523 is coated with anti-adhesion paint to prevent the adhesive tape from adhering to the wheel.

[0059] Adhesive tape cutting:

[0060] First cutting: when the adhesive tape is pasted to the predetermined length, the control system issues an instruction, and the first hydraulic cylinder 519 in the cutting box 517 acts quickly, pushing the first adhesive tape cutting knife 520 to move towards the rubber pad 518 to cut the adhesive tape being conveyed.

[0061] Second cutting: at the same time, the third hydraulic cylinder 538 on the clamping box 530 acts, pushing the second adhesive tape cutting knife 539 to cut the adhesive tape, preparing a section of the adhesive tape head clamped by the clamping jaw 533 for the next adhesive application. After this cutting, the rotating motor 529 can adjust the angle of the clamping box 530 through the rotating part 528 to adapt to the different adhesive application angles of the next sealing strip.

[0062] Pressing and length control

[0063] Pressing enhancement: the adhesive tape continues to be conveyed forward into the pressing assembly 6, and the sealing strip passes between the extrusion roller 604 and the lifting roller 612. The lifting roller 612 provides continuous and flexible pressure under the action of the compression spring 613, ensuring that the adhesive tape is completely pasted with the sealing strip without bubbles or lifting. The rotating handle 607 can synchronously drive the two third lead screws 606 through the transmission belt 609 to adjust the overall height of the lifting roller 612 to adapt to different thicknesses of products.

[0087] After the sealing strip in the area of the pad table 2 is pasted with rubber, one end of the sealing strip is manually passed through the cutting assembly 7 and wound on the surface of the winding disc 810. The fifth motor 809 is started to drive the winding rod 808 to rotate, so that the winding disc 810 rotates to pull one end of the sealing strip to move, so that the sealing strip with the un-pasted rubber strip segment is placed on the surface of the pad table 2. The rubber pasting assembly 5 is reset to the initial position, and the continuous rubber pasting operation is carried out.

[0088] When the short sealing strip is pasted with rubber, the operator can manually place the sealing strip on the surface of the pad table 2, and complete the rubber pasting by one operation of the rubber pasting assembly 5.
