Specific embodiments

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0026] The present application provides a technical solution:

[0027] Please refer to Figures 1 to 4An automatic folding mechanism for producing a mattress, comprising a workbench 1, a folding plate 3 is hinged to the right side of the inside of the workbench 1, a conveying roller 2 is rotatably connected to the top of the workbench 1 and the folding plate 3, moving grooves 10 are formed in the front and rear ends of the upper end of the workbench 1, servo motors 5 are fixedly connected to the front and rear ends of the left side of the workbench 1, and a moving mechanism 6 is arranged between the two moving grooves 10.

[0028] The moving mechanism 6 comprises a first threaded rod 61 rotatably connected to the inside of the moving groove 10, a moving block 62 is threadedly connected to the outer surface of the first threaded rod 61, an electric telescopic rod 63 is fixedly connected to the top of the moving block 62, a protective plate 64 is fixedly connected to the top of the electric telescopic rod 63, a fixed plate 65 is fixedly connected between the two protective plates 64, a first spring 66 is fixedly connected to the top of the fixed plate 65, a plurality of first springs 66 are fixedly connected to the top of a lifting plate 67, and a neat plate 68 is hinged to the top of the front and rear ends of the lifting plate 67.

[0029] The number of the first springs 66 is more than one, and the elastic force is greater than the sum of the gravity of the lifting plate 67 and the neat plate 68.

[0030] The fixed plate 65 is fixedly connected with a moving roller 7, and the top of one end of the two protective plates 64 is provided with a limiting groove 12.

[0031] The right side of the inside of the workbench 1 is provided with a placing cavity 11, the inside of the placing cavity 11 is fixedly connected with a hydraulic cylinder 4, and the output end of the hydraulic cylinder 4 is hinged to the bottom of the folding plate 3.

[0032] By adopting the above technical solution, during use, the compressed mattress is transported to the workbench 1. Then, the operation of the electric telescopic rod 63 drives the protective plate 64 to rise and fall. Simultaneously, the operation of the servo motor 5 drives the first threaded rod 61 to rotate. The rotation of the first threaded rod 61 drives the moving block 62 to move. After the output end of the electric telescopic rod 63 rises, it drives the protective plate 64 to rise. The movement of the moving block 62 drives the electric telescopic rod 63 and the protective plate 64 to move. The movement of the protective plate 64 drives the fixed plate 65 to move. When the fixed plate 65 moves the moving roller 7 to the center of the top of the mattress, the operation of the electric telescopic rod 63 drives the protective plate 64 to fall. The falling of the protective plate 64 drives the moving roller 7 to fall, thus pressing down on the center of the top of the mattress. Subsequently, the operation of the hydraulic cylinder 4 pushes the folding plate 3. The folding plate 3, after being pushed, pushes the top of the mattress, pushing one end of the mattress. The mattress is then folded due to gravity, and the folded mattress falls onto the top of the lifting plate 67. The lifting plate 67, pressed by the weight of the mattress, compresses the first spring 66, causing the aligning plate 68 to descend. During its descent, the aligning plate 68 slides within the limiting groove 12, thus providing a stable clamping effect on both sides of the mattress. Then, as the servo motor 5 reverses its operation, it drives the first threaded rod 61 to rotate in the opposite direction. The rotation of the first threaded rod 61 causes the moving block 62 to move in the opposite direction, thereby causing the electric telescopic rod 63 and the protective plate 64 to move in the opposite direction. The reverse movement of the protective plate 64 causes the lifting plate 67 and the aligning plate 68 to move. The aligning plate 68, during this movement, aligns the top and bottom of the folded mattress, preventing unevenness after folding and avoiding dimensional deviations during subsequent processing. This improves the neatness of the mattress during folding and increases the efficiency of mattress folding.

[0033] Specifically, such as Figures 3-4 As shown, lifting blocks 9 are fixedly connected to the right sides of both the front and rear ends of the fixed plate 65, and a pressing mechanism 8 is provided on the left side inside the limiting groove 12 and the top right side of the protective plate 64.

[0034] The pressing mechanism 8 includes a second threaded rod 81 rotatably connected to the right side of the inside of the limiting groove 12, and a first gear 82 is fixedly connected to the bottom of the outer surface of the second threaded rod 81.

[0035] The pressing mechanism 8 also includes a second gear 83 fixedly connected to the lower left side of the limiting groove 12. A rotating frame 84 is fixedly connected to the top of the second gear 83. A movable groove 13 is opened at the lower end of the rotating frame 84. An adjusting plate 86 is movably connected inside the movable groove 13. A second spring 85 is fixedly connected between the adjusting plate 86 and the movable groove 13. A pressing roller 87 is fixedly connected to the bottom of the adjusting plate 86.

[0036] The second spring 85 is multiple in number, and the elastic force of the second spring 85 is greater than the sum of the gravity of the adjusting plate 86 and the pressing roller 87.

[0037] By adopting the above technical scheme, the lifting block 9 is lowered during the lowering of the lifting plate 67, the second threaded rod 81 is rotated during the lowering of the lifting block 9, the first gear 82 is rotated by the rotation of the second threaded rod 81, the second gear 83 is rotated by the rotation of the first gear 82, and the rotating frame 84 is rotated by the rotation of the second gear 83. The rotating frame 84 is rotated to the top of the mattress, and the rotating frame 84 is moved by the movement of the protective plate 64. The adjusting plate 86 and the pressing roller 87 are moved during the movement of the rotating frame 84. The pressing roller 87 during the movement presses the top of the mattress, avoids the mattress from being offset during the extraction of the moving roller 7 from the inside of the mattress, and satisfies the stable fitting effect of the top and the bottom of the mattress by the setting of the pressing roller 87, which is beneficial to improve the neatness of the subsequent processing of the mattress.

[0038] Working principle: when in use, the mattress is compressed by the compressor and delivered to the workbench 1. The mattress is folded in half and delivered to the top of the folding plate 3 by the rotation of the conveying roller 2. Then, the lifting of the electric telescopic rod 63 drives the lifting of the protective plate 64, and the work of the servo motor 5 drives the rotation of the first threaded rod 61. The movement of the moving block 62 and the electric telescopic rod 63 is driven by the rotation of the first threaded rod 61. The movement of the protective plate 64 is driven by the movement of the electric telescopic rod 63. The fixed plate 65 and the moving roller 7 are moved by the movement of the protective plate 64. When the moving roller 7 moves to the center of the mattress, the lifting of the protective plate 64 and the fixed plate 65 is driven by the work of the electric telescopic rod 63. The moving roller 7 presses the top of the mattress. Then, the work of the hydraulic cylinder 4 drives the pushing of the folding plate 3. The folding plate 3 pushes the mattress to fold. The mattress falls to the top of the fixed plate 65. After the mattress presses the fixed plate 65, the first spring 66 drives the neat plate 68 to be clamped in the limiting groove 12, so that the neat plate 68 clamps the two sides of the mattress.

[0039] Meanwhile, the fixed plate 65 is lowered, the lifting block 9 is slid on the outer surface of the second threaded rod 81, the second threaded rod 81 is rotated, the first gear 82 is rotated by the rotation of the second threaded rod 81, the second gear 83 is rotated by the meshing of the first gear 82 and the second gear 83, the rotating frame 84 is rotated by the rotation of the second gear 83, thereby the adjusting plate 86 and the pressing roller 87 are rotated, the pressing roller 87 is used for pressing and rolling the top of the mattress, and the first threaded rod 61 is rotated by the working of the servo motor 5, the moving block 62 is moved by the rotation of the first threaded rod 61, and the alignment plate 68 is used for aligning the two sides of the mattress, so that the alignment during the folding of the mattress is improved.

[0040] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
