[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a foaming device for sponge production includes a processing tank 1; a connecting plate 2 is fixedly connected to one side of the top of the processing tank 1, a drive motor 3 is fixedly connected to the surface of the connecting plate 2, an A toothed shaft 4 is fixedly connected to the output end of the drive motor 3, a toothed belt 5 is sleeved on the surface of the A toothed shaft 4, a B toothed shaft 6 is sleeved on one side inside the toothed belt 5, a mixing component 7 for improving the foaming efficiency of sponge production is fixedly connected to the bottom of the A toothed shaft 4, and a drive component 8 for scraping off the residual raw materials on the inner wall surface of the processing tank 1 during the sponge foaming process is fixedly connected to the bottom of the B toothed shaft 6; the drive component 8 includes a B connecting rod 81 fixedly connected to the bottom of the B toothed shaft 6, a reciprocating screw 82 fixedly connected to one end of the B connecting rod 81 through the top of the processing tank 1, a drive block 83 is provided on the surface of the reciprocating screw 82, a fixing ring 84 is fixedly connected to one side of the drive block 83, and a flexible ring plate 85 with the same diameter as the inside of the processing tank 1 is sleeved on the surface of the fixing ring 84.

[0025] During operation, the drive motor 3 drives the toothed shaft 6 to rotate synchronously via the toothed shaft A 4 and the toothed belt 5, enabling the mixing component 7 and the drive component 8 to operate in parallel. The reciprocating screw 82 of the drive component 8 drives the drive block 83 to move up and down along the square slide 9. The flexible ring plate 85 closely adheres to the inner wall of the processing tank 1 to scrape away residual materials, avoiding the downtime required for traditional manual cleaning. The flexible ring plate 85 is made of silicone-nylon composite material with a Shore hardness of 50A. Driven by the reciprocating screw 82, it adapts to the ellipticity deviation of the inner wall of the processing tank 1 through the guide of the limiting bead 13 and the circular slide 12, thereby improving the wall scraping coverage.

[0026] Furthermore, the mixing component 7 includes an A connecting rod 71 fixedly connected to the bottom of the A toothed shaft 4. One end of the A connecting rod 71 passes through the top of the processing tank 1 and is fixedly connected to a central shaft 72. The surface of the central shaft 72 is provided with a number of irregularly shaped pieces 73 at equal intervals from top to bottom. The irregularly shaped pieces 73 are horizontally symmetrical hooks.

[0027] During operation, the central shaft 72 of the mixing component 7 drives the irregularly shaped sheet 73 to rotate at high speed. The hook-shaped sheet 73 generates turbulent shear force, which increases the foaming rate of polyurethane raw materials and improves the mixing uniformity. The left and right symmetrical hook-shaped design of the irregularly shaped sheet 73 forms a bidirectional vortex when rotating, which increases the contact area between the foaming agent and the raw materials, increases the bubble density, and improves the uniformity of sponge pores.

[0028] Furthermore, a circular groove 12 is provided on the other side of the interior of the processing tank 1. A limiting bead 13 is slidably connected inside the circular groove 12. One side of the limiting bead 13 is fixedly connected to one side of the flexible ring plate 85. A square groove 9 is provided on one side of the inner wall of the processing tank 1. The interior of the square groove 9 is slidably connected to both sides of the drive block 83.

[0029] During operation, the guide structure design of the limiting bean 13 and the circular slide 12 enables the flexible ring plate 85 to self-adaptively fit, solving the problem of dead angles in the scraping caused by tank deformation and improving the equipment's compatibility and adaptability under complex working conditions. The drive block 83 is embedded with square slide 9 on both sides, restricting it to move only in the vertical direction. The pitch of the reciprocating screw 82 is used to improve the stroke accuracy and increase the scraping coverage.

[0030] Furthermore, a connecting rod 10 is fixedly connected to one side of the connecting plate 2, and a limiting shaft 11 is fixedly connected to the bottom of one end of the connecting rod 10. The bottom of the limiting shaft 11 is rotatably connected to the top of the toothed shaft 6 of B.

[0031] During operation, the connecting rod 10 is fixed to the connecting plate 2, and the limiting shaft 11 is connected to the top bearing of the toothed shaft 6 to limit its radial runout, thereby improving the transmission efficiency of the toothed belt 5.

[0032] Furthermore, a feeding pipe 14 for feeding raw materials for sponge production is connected through to the other side of the top of the processing tank 1, and an A stop valve for opening and closing is provided on the surface of the feeding pipe 14.

[0033] During operation, the feeding pipe 14 vertically penetrates the top of the treatment tank 1. The opening of valve A is adjusted by a threaded knob to support quantitative feeding and prevent excessive raw materials from sticking to the tank opening. The discharge pipe 15 is placed at an angle at the bottom of the treatment tank 1. Valve B is connected by a flange and discharges raw materials after opening.

[0034] Working principle: Open valve A of feeding pipe 14, and inject polyurethane prepolymer, foaming agent, and other raw materials into processing tank 1 through feeding pipe 14 according to the formula ratio. After feeding is completed, close valve A to prevent raw material volatilization. Start drive motor 3, and A toothed shaft 4 rotates clockwise, driving B toothed shaft 6 to rotate synchronously through toothed belt 5. The central shaft 72 of mixing component 7 rotates at high speed with A toothed shaft 4, driving the irregularly shaped sheet 73 to generate a bidirectional vortex. The raw materials are fully processed under the shearing force of the hook-shaped irregularly shaped sheet 73. The mixing and foaming reaction is initiated. The toothed shaft 6 (B) drives the reciprocating screw 82 to rotate via the connecting rod 81 (B). The drive block 83 moves up and down along the square chute 9. Under the guidance of the limiting bean 13 and the circular chute 12, the flexible ring plate 85 scrapes off the residual raw materials by adhering to the inner wall of the processing tank 1. When the foaming height reaches 80% of the tank volume, the drive motor 3 is turned off and the B stop valve of the discharge pipe 15 is opened. The residual waste liquid and the scraped solid residue are discharged. The flexible ring plate 85 continues to scrape the wall to the bottom to ensure that there is no residue on the tank wall.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
