Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and more particularly to a conveying device for the preparation of latex mattresses. Background Technology

[0002] Latex mattresses are widely used in the home mattress industry due to their good elasticity, support, and breathability. The manufacturing process of a latex mattress typically involves first transporting liquid latex to the appropriate processing location, followed by pouring, molding, foaming, or other subsequent processes to complete the mattress production.

[0003] In existing latex conveying methods, liquid latex is typically delivered to the target workstation via emulsion tanks, pipelines, or manual handling. During actual conveying, when the liquid latex remains in the tank for an extended period, localized sedimentation, stratification, or decreased fluidity can easily occur. This is especially true when the conveying distance is long, the conveying time is extended, or the tank is frequently started and stopped, making the internal state of the latex more susceptible to changes, thus affecting its performance after delivery.

[0004] Furthermore, existing latex tanks typically require manual valve opening or independent drive mechanisms to unload after reaching their destination, involving numerous steps and demanding dedicated opening and closing controls, resulting in an inefficient overall process. Therefore, there is an urgent need for a latex tank transport device that ensures uniform transport of latex liquid and facilitates easy unloading. Summary of the Invention

[0012] In addition, a preferred structure is that multiple elastic seats are fixedly provided on the outer side of the movable plate, the piston rods of the elastic seats all extend into the side cavity and are connected to the back plate, and the elastic seats are of the slow-release type.

[0013] Furthermore, in a preferred configuration, side seats are installed on both sides of the movable plate, and deformable components are installed at the bottom of each side seat. A fixing frame for guiding the deformation direction of the side seats is fixedly installed on the movable plate on the outer side of the side seats, and a mother anti-jamming inclined surface and a side push inclined surface are provided on the side seats.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] See Figure 1-3 A conveyor 2 is fitted onto the overhead rail 1, and an emulsion tank 21 is mounted on the conveyor 2. An outlet 22 is located at the bottom of the emulsion tank 21, and a base 31 is fixedly installed inside the emulsion tank 21. Multiple outlet channels 311 are vertically oriented through the base 31, and a rotating shaft 3 is vertically mounted on the top of the base 31, extending upwards from inside the emulsion tank 21. Multiple stirring blades 32 are mounted on the rotating shaft 3 to stir the latex liquid inside the emulsion tank 21, ensuring it remains uniform.

[0021] It is worth noting that both the overhead rail 1 and the conveyor 2 are existing technologies, and their specific driving methods, guiding mechanisms, and other basic conveying structures are common knowledge known to those skilled in the art, so they will not be elaborated further.

[0022] See Figure 4-7 A gear 33 is fixedly fitted on the part of the rotating shaft 3 that extends from the top of the emulsion tank 21. A threaded part 34 is provided above the gear 33, and a smooth part 341 is provided above the threaded part 34.

[0023] The rotating shaft 3 has a vertically penetrating inner cavity 30, and a movable rod 4 is vertically inserted into the inner cavity 30. The movable rod 4 can slide up and down within the inner cavity 30.

[0024] The bottom of the movable rod 4 is fixedly equipped with a liquid outlet seat 41, which is located below the chassis 31 and at the liquid outlet 22. Multiple thin rods 411 are fixedly installed on the liquid outlet seat 41 corresponding to the liquid outlet channel 311. A blocking element 412 for sealing the liquid outlet channel 311 is fixedly installed at the top of each thin rod 411, and a blocking cap 413 is fixedly installed at the top of the blocking element 412. By moving the liquid outlet seat 41 up and down with the movable rod 4, the blocking element 412 and the blocking cap 413 can move synchronously, thereby opening or closing the liquid outlet channel 311.

[0025] The diameter of the plug 412 is adapted to the liquid outlet channel 311. When the plug 412 is located inside the liquid outlet channel 311 and is reinforced by the plug cover 413, the liquid outlet channel 311 can be blocked.

[0026] When the plug 412 and the plug cap 413 move upward, the thin rod 411 moves into the liquid outlet channel 311, at which point the material can be discharged through the liquid outlet channel 311.

[0027] See Figure 8-10 A top column 7 is vertically fixed downwards on the conveyor 2. The top column 7 has a regular hexagonal cross-section. A cavity 40 adapted to the top column 7 is opened on the movable rod 4, so that the movable rod 4 is sleeved on the outside of the top column 7. A movable part 5 is fixedly installed on the top of the movable rod 4, and the movable part 5 is sleeved on the top column 7. A locking part 6 is vertically movable on the top of the movable part 5, and the locking part 6 is also sleeved on the top column 7.

[0028] Because the top column 7 is a regular hexagon, the movable rod 4, movable part 5, and locking part 6 can only move vertically and cannot rotate. The movable part 5 is provided with a main push slope 51, and the two sides of the movable part 5 are provided with a storage side groove 52 and a side push slope 53. The storage side groove 52 is provided with a sub anti-jamming slope 521.

[0029] See Figure 11-14 A back plate 61 is fixedly mounted on the locking member 6, and a movable plate 62 is laterally movably mounted on the back plate 61. A side cavity 622 is formed on the movable plate 62, through which the movable plate 62 is fitted onto the back plate 61, allowing it to move laterally along the back plate 61. A guide post 623 is fixedly mounted inside the side cavity 622 to guide the lateral movement of the movable plate 62.

[0030] Multiple elastic seats 624 are fixedly installed on the outer side of the movable plate 62. The piston rods 625 of the elastic seats 624 all extend into the side cavity 622 and are connected to the back plate 61. The elastic seats 624 adopt a slow-release structure. It is worth noting that the spring seats 624 and piston rods 625 are existing technologies. In the actual implementation of this solution, other structures with the same elastic slow-release and reset function can be used as substitutes.

[0031] The movable plate 62 is provided with a threaded groove 621 that is adapted to engage with the threaded part 34 of the rotating shaft 3, so that the rotating shaft 3 can drive the movable plate 62 to move vertically during rotation.

[0032] Side seats 63 are installed on both sides of the movable plate 62, and deformable parts 633 are installed at the bottom of the side seats 63. A fixing frame 64 is fixedly installed on the movable plate 62 on the outside of the side seats 63. The fixing frame 64 is used to limit and guide the deformation direction of the side seats 63, so that the side seats 63 can only deform through the mother anti-locking slope 631 and the daughter anti-locking slope 521.

[0033] The side seat 63 is provided with a female anti-locking inclined surface 631 and a side-push inclined surface 632. The female anti-locking inclined surface 631 is adapted to the female anti-locking inclined surface 521 on the movable part 5, and the side-push inclined surface 632 is adapted to the side-push inclined surface 53 on the movable part 5.

[0034] An outer frame 8 is fixedly installed on the front end of the unloading section on the hanging rail 1. A rack 81 that is adapted to and can mesh with the gear 33 is installed on the outer frame 8. A drive seat 82 is fixedly installed on the outer frame 8 at the end of the rack 81. A main push inclined surface 821 and a secondary push inclined surface 822 are provided on the drive seat 82. Both the main push inclined surface 821 and the secondary push inclined surface 822 are adapted to the main push inclined surface 51 on the movable part 5.

[0035] In this embodiment, during the preparation and conveying of the latex mattress, the conveyor 2, carrying an emulsion tank 21 containing latex liquid, moves forward along the overhead rail 1. This is prior art and will not be described in detail.

[0036] When the conveyor 2 moves to the outer frame 8 of the unloading section, the gear 33 on the rotating shaft 3 begins to contact and mesh with the rack 81 on the outer frame 8. As the conveyor 2 continues to move forward, the rack 81 drives the gear 33 to rotate, which in turn drives the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 causes the stirring blades 32 inside the emulsion tank 21 to rotate synchronously, thereby automatically stirring the latex liquid to ensure the uniformity of the latex liquid.

[0037] During the meshing and rotation of gear 33 and rack 81, the threaded portion 34 on shaft 3 also rotates synchronously. At this time, the threaded groove 621 on movable plate 62 is engaged with the threaded portion 34. Since locking member 6 and movable member 5 are restricted from rotating by hexagonal top post 7, the rotation of threaded portion 34 on shaft 3 will drive movable plate 62 and locking member 6 to move upward synchronously along top post 7. This upward movement gradually releases the locking member 6 from its original locking state above movable member 5, preparing for the subsequent upward movement and unloading of movable member 5.

[0038] As the movable plate 62 continues to rise, when it completely passes through the threaded portion 34 and reaches the upper smooth portion 341, since the height of the smooth portion 341 is the same as that of the movable plate 62 and it has no threads, even if the rack 81 is long enough to cause the rotating shaft 3 to continue rotating, the movable plate 62 and the locking member 6 will not continue to rise, thus controlling the rising height. During this process, when the side seat 63 moves upward, the cooperation of the female anti-locking inclined surface 631 and the female anti-locking inclined surface 521 can automatically cause the deformable member 633 to deform outward, allowing the side seat 63 to smoothly disengage from the receiving side groove 52 and preventing the structure from jamming.

[0039] Furthermore, after gear 33 has completely passed through rack segment 81, shaft 3 stops rotating. At this time, conveyor 2 continues to move forward, and movable part 5 moves to a position contacting drive seat 82. The main push-receiving inclined surface 51 on movable part 5 first contacts the main push-in inclined surface 821 on drive seat 82. Under the pushing action of main push-in inclined surface 821, movable part 5 and movable rod 4 are lifted upward to the first height. The rise of movable rod 4 drives the bottom liquid outlet seat 41, thin rod 411, plug 412 and plug cover 413 to move upward synchronously. At this time, plug 412 disengages from the liquid outlet channel 311 on chassis 31, and the liquid outlet channel 311 is opened.

[0040] At the same time, the lower outlet 22 moves to the top of the corresponding external collection tank. At this time, the conveyor 2 temporarily stops operating, and the latex liquid in the emulsion tank 21 flows downward through the outlet channel 311 and the outlet 22, at which point the emulsion can be fed.

[0041] Furthermore, an anti-stick coating is provided on the inner wall of the emulsion tank 21. This anti-stick coating reduces the amount of latex residue adhering to the inner wall of the emulsion tank 21. Also, after the latex is dispensed, the conveyor 2 has a set waiting time at the drive seat 82 to allow any remaining droplets at the outlet 22 to flow completely, thus preventing continuous dripping of liquid during subsequent movement of the conveyor 2. This is prior art and will not be elaborated further.

[0042] After the material is unloaded, the conveyor 2 restarts and continues to move forward. At this time, the main push-receiving inclined surface 51 of the movable part 5 contacts the secondary push-receiving inclined surface 822 on the drive seat 82. Under the pushing action of the secondary push-receiving inclined surface 822, the movable part 5 and the movable rod 4 are lifted upward to a second height. During the first lift, the movable part 5 does not contact the side seat 63. During the second lift, the side push-receiving inclined surfaces 53 on both sides of the movable part 5 contact and push the side push-receiving inclined surfaces 632 on the side seat 63. Through the force transmission of the side seat 63, the movable plate 62 is pushed horizontally outward. After the movable plate 62 moves outward, the screw groove 621 on it no longer meshes with the threaded part 34 of the rotating shaft 3, thereby releasing the threaded engagement relationship, and at this time the piston rod 625 retracts into the elastic seat 624.

[0043] After the conveyor 2, carrying the entire structure, has completely passed the drive seat 82, the moving part 5, locking part 6, moving rod 4, and liquid outlet seat 41, due to the loss of external pushing support, will automatically fall back to their original positions under their own gravity. During the fall, the blocking part 412 and the blocking cover 413 will re-seal the liquid outlet channel 311 on the chassis 31, stopping the liquid discharge. Because the elastic seat 624 adopts a slow-release design, when the moving plate 62 moves horizontally outward, the piston rod 625 will slowly release pressure, allowing the moving plate 62 to slowly return to its original horizontal position inward during the component fall, ensuring that the screw groove 621 can re-align and re-engage with the threaded part 34, completing the entire cycle of conveying, mixing, discharging, and resetting.

[0044] In this invention, the latex liquid can be conveyed by the conveyor 2 driving the emulsion tank 21 to move along the hanging rail 1. The meshing transmission of the gear 33 and the rack 81 drives the rotating shaft 3 to rotate, thereby causing the stirring blade 32 to automatically stir the latex liquid, so that the latex liquid is in a uniform state. Through the linkage structure of the movable rod 4 and the sealing part 412, the liquid outlet channel 311 can be automatically opened for feeding after being conveyed to the designated position, reducing manual operation steps.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
