[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5 In this embodiment of the utility model, the non-woven heat sealing device for the bagged spring pack includes two mounting frames 1. Two movable plates 3 are slidably installed on the inner side of the two mounting frames 1. The two movable plates 3 are symmetrically distributed vertically and are synchronously connected by a synchronization mechanism. A bracket 2 is welded to the top of the two mounting frames 1. An electric push cylinder 5 is installed on the top plate of the bracket 2. The piston rod of the electric push cylinder 5 passes through to the bottom of the top plate of the bracket 2 and is fixedly connected to the top of the movable plate 3 above. The synchronization mechanism is installed inside the protective cover 6. A docking groove 13 with one end closed is opened in the horizontal plate part opposite to the two movable plates 3. A docking block 12 is slidably installed inside the docking groove 13. A mounting plate 4 is installed on the opposite side of the two docking blocks 12. A connecting mechanism for limiting the docking block 12 is installed inside the movable plate 3. Two heat sealing plates 11 are installed on the opposite side of the two mounting plates 4. An insertion groove 14 that connects with the connecting mechanism is opened on one side of the docking block 12.

[0015] In this embodiment: First, the tubular nonwoven fabric passes between the two moving plates 3. After the bed spring enters the nonwoven fabric, the electric push cylinder 5 is activated, which pushes the upper moving plate 3 downward. The upper moving plate 3 drives the lower moving plate 3 to move synchronously through the synchronization mechanism. The two moving plates 3 move in opposite directions, so that the two mounting plates 4 move towards each other until the heat-sealing plate 11 clamps and heat-seales the nonwoven fabric. During the long-term use of the heat-sealing plate 11, aging phenomena (such as cracking, wear, etc.) will occur. At this time, the connecting mechanism is pushed by the pushing mechanism to unlock the docking block 12. The mounting plate 4 can then be removed and replaced with a new mounting plate 4 with a new heat-sealing plate 11. The docking block 12 on the new mounting plate 4 is slidably installed into the docking groove 13. The connecting mechanism limits the newly installed mounting plate 4. This method facilitates the replacement of the heat-sealing plate 11.

[0016] Please refer to this carefully. Figure 2 The synchronization mechanism includes a groove 7 inside the mounting frame 1. The two ends of the movable plate 3 are integrally formed with sliders that are slidably connected to the groove 7. A first rack 8 is installed at one end of the upper slider, and a second rack 9 is installed at one end of the lower slider. The inner sides of the first rack 8 and the second rack 9 are meshed with gears 9 that are rotatably mounted to the mounting frame 1.

[0017] In this embodiment: when the upper movable plate 3 moves, the first rack 8 connected to the upper movable plate 3 moves synchronously. The moving first rack 8 drives the second rack 9 to rotate. The rotating second rack 9 drives the gear 9 to move in the opposite direction. The gear 9 moving in the opposite direction drives the lower movable plate 3 to move synchronously, so as to achieve the purpose of the two sets of heat-sealing plates 11 moving closer or further away from each other, and to achieve the effect of heat sealing and separation after heat sealing.

[0018] Please refer to this carefully. Figure 5 The pushing mechanism includes a connecting spring 25 fixedly installed inside the long rod 17. A sliding rod 24 extending through the outside of the long rod 17 is fixedly installed at the other end of the connecting spring 25. A handle 18 is fixedly installed at the end of the sliding rod 24 located outside the long rod 17. A groove 26 for sliding of a protrusion 27 is opened in the inner cavity of the long rod 17. The protrusion 27 is located on the outer periphery of the long rod 17 and outside the long rod 17. A limiting plate 28 is integrally formed at the end of the long rod 17 away from the extrusion plate 16. The side wall of the limiting plate 28 is flush with one side wall of the groove 26.

[0019] In this embodiment: when unlocking the connecting mechanism is not required, the connecting spring 25 drives the sliding rod 24 to be in the reset state. At this time, the protrusion 27 is aligned with the slot 26. When the handle 18 is subjected to force, the handle 18 pushes the sliding rod 24 to slide. At this time, the protrusion 27 slides in the slot 26 and will not push the connecting mechanism. When it is necessary to unlock the connecting mechanism, by rotating the handle 18, the handle 18 drives the sliding rod 24 to rotate synchronously and causes the protrusion 27 to be misaligned with the slot 26. At this time, pushing the handle 18 to move it will push the long rod 17 to move through the protrusion 27. This avoids the problem of accidental unlocking due to accidental touch.

[0020] Please refer to this carefully. Figure 4 The connecting mechanism includes a receiving groove 15 formed inside the horizontal plate of the movable plate 3. A guide rod 22 is fixedly installed on the inner wall of the receiving groove 15. An extrusion plate 16 is slidably connected to the guide rod 22 inside the receiving groove 15. A return spring 23 abuts against the outer side of the extrusion plate 16 and one side of the inner wall of the receiving groove 15. The return spring 23 is sleeved on the outer periphery of the guide rod 22. Both ends of the extrusion plate 16 are integrally formed with extrusion bevels. The connecting mechanism also includes a pressure plate 19 abutting against both ends of the extrusion plate 16. One end of the pressure plate 19 The pressure plate 19 extends into the inner cavity of the docking groove 13. At one end of the inner cavity of the docking groove 13, a first pressure inclined surface is formed. At one end of the inner cavity of the receiving groove 15, a second pressure inclined surface that matches the extrusion inclined surface is integrally formed. The moving plate 3 has a strip groove 20 inside to accommodate the push spring 21. One end of the push spring 21 is fixedly connected to the pressure plate 19. The outer wall of the extrusion plate 16 is integrally formed with an outwardly extending long rod 17. A push mechanism that extends into the interior of the long rod 17 is installed inside the long rod 17.

[0021] In this embodiment: when the long bar 17 moves, the long bar 17 pushes the pressing plate 16 to move synchronously. At this time, the pressing plate 16 slides along the outer wall of the guide bar 22 and presses the return spring 23. At this time, the pressing slope and the second pressing slope gradually separate. Then the pushing spring 21 pushes the pressure plate 19 to move towards the inner wall of the receiving groove 15. At this time, one end of the pressure plate 19 separates from the insertion groove 14, and the mounting plate 4 can be removed. After removal, the force applied to the pushing mechanism is removed. At this time, the return spring 23 pushes the pressing plate 16 to reset. The reset pressing plate 16 then pushes the pressure plate 19 to reset through the pressing slope and the second pressing slope. When installing the new mounting plate 4, the mating block 12 on the new mounting plate 4 slides into the mating groove 13 until one end contacts the second pressure-bearing inclined surface of the pressure plate 19. At this time, the pressure plate 19 is forced to move into the receiving groove 15 until the insertion groove 14 is aligned with one end of the pressure plate 19. At this time, the reset spring 23 resets and pushes, so that one end of the pressure plate 19 is inserted into the insertion groove 14, thus completing the position limit of the mounting plate 4.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
