Description
Technical Field

[0002] Elevator brake friction pads are a crucial component of elevators. They are primarily used during the braking process to generate braking force through friction, bringing the elevator to a stop. Their main function is to ensure the safe operation of the elevator and prevent dangerous situations such as unexpected descent or overshooting in the event of power outages or malfunctions.
[0003] In the processing of elevator friction pads, an adhesive coating device is required to coat the friction pads with adhesive. Existing technology, such as patent publication number CN220590557U, discloses an adhesive coating device for motorcycle friction pads, including a base plate and a support column.

[0025] Example 1
[0026] Reference Figures 1-4 This utility model discloses a dynamic adhesive application device for elevator friction plates, including an adhesive application tube 1, a positioning seat 2, a first shaft 3 fixedly mounted on the bottom of the positioning seat 2; a grooved wheel mechanism, including a cooperating active dial 4 and a grooved wheel 5, a second shaft 6 fixedly mounted on the bottom of the active dial 4, a third shaft 7 passing through the center of the grooved wheel 5, the first shaft 3 and the second shaft 6 being connected in a transmission manner, and an incomplete gear 8 fixedly mounted on the top of the third shaft 7; and an adhesive application mechanism, including a base plate 9, a movable seat 10 slidably connected to the base plate 9, a rack 11 fixedly mounted on the side wall of the movable seat 10 that cooperates with the incomplete gear 8, a spring 12 connected between one end of the movable seat 10 and the base plate 9, and an adhesive application tube 1 connected to the end of the movable seat 10 away from the spring 12.
[0027] With the above structure, the first shaft 3 can rotate the friction plate on the positioning seat 2 during glue application. The rotation of the first shaft 3 will drive the second shaft 6 to rotate. The second shaft 6 will intermittently drive the third shaft 7 to rotate through the active dial 4 and the grooved wheel 5. The third shaft 7 will intermittently drive the moving seat 10 with rack 11 to move along the diameter direction of the friction plate through the incomplete gear 8, so as to drive the glue application tube 1 to apply glue to the glue application surface in multiple turns. When the glue application surface width is reached, the glue application tube 1 first stops applying glue, the toothless part of the incomplete gear 8 rotates to the rack 11, and then the rotation of the first shaft 3 stops. Under the action of the spring 12, the glue application tube 1 returns to the initial position, the friction plate is replaced, and the next friction plate is glued. While driving the positioning seat 2 to rotate, the glue application tube 1 moves along the diameter direction of the friction plate, realizing continuous glue application to the friction plate with a wide glue application surface, and the control cost is low.
[0028] In detail, in this embodiment, a three-jaw chuck 13 is fixed on the top of the positioning seat 2. The three-jaw chuck 13 is an existing product. If a manual three-jaw chuck is used, the model can be K11 series.
[0029] In detail, in this embodiment, the transmission mechanism includes a first pulley 14 and a second pulley 15. The first pulley 14 is fixedly sleeved on the outside of the first shaft 3, and the second pulley 15 is fixedly sleeved on the outside of the second shaft 6. The first pulley 14 and the second pulley 15 are connected by a transmission belt 16. The first shaft 3 drives the second shaft 6 to rotate through the first pulley 14, the second pulley 15 and the transmission belt 16. This enables the active dial 4 to rotate when the friction plate on the positioning seat 2 rotates, thereby driving the movable seat 10 on which the glue applicator tube 1 is mounted to move through the grooved wheel 5, the third shaft 7, the incomplete gear 8, the rack 11 and other structures.
[0030] In this embodiment, the grooved wheel 5 is a four-groove grooved wheel. Preferably, the transmission ratio of the first pulley 14 and the second pulley 15 is 1:1, so that during the rotation of the friction plate on the positioning seat 2, the active dial 4 drives the grooved wheel 5 to rotate once, moving the glue application tube 1 from the outer ring to the next glue application ring. In this way, after the friction plate on the positioning seat 2 rotates multiple times, such as three times, the glue application tube 1 will apply glue to the glue application surface of the friction plate in multiple rounds.
[0031] In detail, in this embodiment, a horizontal plate 17 is fixed to one side wall of the substrate 9, and a slide rail 18 is fixed to the top of the horizontal plate 17. The movable seat 10 is slidably connected to the slide rail 18. The horizontal plate 17 is fixed to one side of the substrate 9 by a triangular plate, which can provide stable support. The movable seat 10 can be fixed to the slide block on the slide rail 18, so that the movable seat 10 can move smoothly on the slide rail 18.
[0032] Example 2
[0033] Reference Figures 1-4 Based on the same concept as in Embodiment 1 above, this dynamic adhesive application device for elevator friction plates also includes a mounting plate 19 fixed to one end of the movable seat 10 away from the spring 12. A telescopic cylinder 20 is fixed on the mounting plate 19, which provides stable support for the telescopic cylinder 20. A mounting base 21 is provided at the bottom of the mounting plate 19, and a guide rod 22 passing through the mounting plate 19 is fixed to the top of the mounting base 21. The power end of the telescopic cylinder 20 is fixedly connected to the top of the mounting base 21. The telescopic cylinder 20 can be a pneumatic cylinder. By controlling the telescopic cylinder 20, the mounting base 21 is driven to adjust its height, thereby adjusting the height of the adhesive application tube 1, which facilitates adhesive application and disassembly / removal of the friction plates. An adhesive pump 23 and an adhesive application tube 1 are mounted on the mounting base 21. The adhesive application tube 1 is connected to external adhesive liquid through the adhesive pump 23. The principle of the adhesive liquid pumping out is existing technology and will not be described in detail.
[0034] In detail, this embodiment also includes a support platform 24, and a reduction motor 25 is fixed at the bottom of the support platform 24. The output end of the reduction motor 25 is fixedly connected to the bottom end of the first shaft 3. When it is necessary to apply glue, the reduction motor 25 is started to drive the first shaft 3 to rotate.
[0035] Working principle:
[0036] The friction pad to be coated with adhesive is fixed by the three-jaw chuck 13. Then, the geared motor 25 and the adhesive pump 23 are started. When the adhesive application tube 1 applies adhesive to the spraying surface of the friction pad, the geared motor 25 drives the positioning seat 2 to rotate through the first shaft 3, thereby driving the friction pad to rotate and perform adhesive injection on the outer ring of the friction pad. After the first shaft 3 rotates one revolution, the active dial 4 will drive the adhesive application tube 1 to move a small distance along the diameter direction of the friction pad through the grooved wheel 5, the third shaft 7, the incomplete gear 8, the rack 11, and the moving seat 10. For a certain distance, the glue-applying tube 1 performs a second round of glue application on the friction plate. This process is repeated. After the friction plate on the positioning seat 2 rotates multiple times, the glue-applying tube 1 applies glue to the coating surface multiple times. When the width of the coating surface is reached, the glue-applying tube 1 stops applying glue and the first shaft 3 rotates. The glue-applying tube 1 first stops applying glue, and the toothless part of the incomplete gear 8 rotates to the rack 11. Then, the rotation of the first shaft 3 stops. Under the action of the spring 12, the glue-applying tube 1 returns to its initial position, and the friction plate is replaced to apply glue to the next friction plate.
[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
