[0023] Reference Figure 1-5 A feeding mechanism for a sponge foaming machine includes a foaming machine body 1. The foaming machine body 1 is provided with a feeding mechanism 2. The feeding mechanism 2 includes a support base 21. A screw drive unit 22 is vertically arranged inside the support base 21. A movable connecting frame 23 is provided at the front end of the support base 21 through the screw drive unit 22. The support base 21 is connected to a feeding component 24 through the movable connecting frame 23.

[0024] Furthermore, the feeding assembly 24 includes a feeding box, and the bottom of the feeding box is provided with a discharge port. The discharge port is equipped with a discharge valve 25. The bottom of the discharge valve 25 is provided with a detachable conveying hose 26. Both ends of the outer wall of the conveying hose 26 are fitted with flanges. The top of the flanges on the top of the conveying hose 26 is provided with multiple mounting parts 3 arranged in a circular array at equal intervals. The conveying hose 26 and the discharge valve 25 are limited by the mounting parts 3. The bottom of the conveying hose 26 is movably fitted with a detachable limiting cover 5.

[0025] Meanwhile, the mounting component 3 includes a fixing block 31, a T-shaped extension block 32 is mounted on the top of the fixing block 31, and a movable clip 33 is slidably sleeved on the outside of the T-shaped extension block 32, and the outer diameter of the movable clip 33 is consistent with the outer diameter of the fixing block 31.

[0026] Meanwhile, the unloading valve 25 includes a flange part two, which has an insertion hole 251 for the installation part 3 to pass through, and guide blocks 252 are symmetrically installed on both sides of the insertion hole 251. A magnetic positioning plug 4 is magnetically attached to the flange part two outside the corresponding installation part 3.

[0027] Furthermore, the fixed block 31 has a sliding groove 1 on its exterior located at the corresponding guide block 252, and the movable clip 33 has a sliding groove 2 on its exterior located at the corresponding guide block 252.

[0028] Furthermore, limit blocks 41 are symmetrically installed on both sides inside the magnetic positioning plug 4, and the cross-sectional area of ​​the limit blocks 41 is the same as that of the guide block 252.

[0029] Meanwhile, a placement cavity is provided on one side of the limiting cover 5 at the flange part at the bottom of the conveying hose 26, and multiple extended protrusions 51 are arranged in a circular array at equal intervals inside the placement cavity.

[0030] Furthermore, a sliding groove is provided in the flange portion at the bottom of the delivery hose 26 at the extension protrusion 51.

[0031] The top of the flange part 2 has a magnetic groove 253 with opposite polarity to the magnetic positioning plug 4.

[0032] It is worth noting that the foaming machine body (the attached diagram is only a partial structural schematic diagram) includes a foaming barrel, and the specific structure and working principle of the foaming machine body, the screw drive unit 22, and the discharge valve 25 are all existing technologies that are currently publicly available on the market, so they will not be described in detail. At the same time, the feeding box of the feeding component 24 is equipped with a stirring component, and the stirring component is driven by a drive unit. The top of the feeding box is provided with a feeding port. The specific structure, connection method, and working principle of the stirring component and the drive unit are all existing technologies that are currently publicly available on the market, so they will not be described in detail. In addition, the screw drive unit 22 is equipped with a dustproof sealing component.

[0033] In this embodiment, the height of the feeding component is adjusted by the screw drive unit, and the feeding component is lowered so that the user can put in the raw materials required for foaming the sponge through the feed port. Then, the driving unit drives the stirring component to rotate so that the stirring component can perform preliminary mixing treatment on the raw materials entering the feeding box.

[0034] Then, the height of the filter assembly is raised by the screw drive unit until the outlet of the feeding assembly is higher than the foaming barrel of the foaming machine body. Then, the limiting cover 5 is rotated until the extended protrusion is aligned with its sliding groove. The limiting cover 5 is then separated from the conveying hose. One end of the conveying hose is then connected to the preset, fixed receiving interface on the foaming barrel body, and the unloading valve is opened to allow the raw material in the feeding box to enter the foaming barrel body along the conveying hose. The foaming machine then foams the raw material.

[0035] Furthermore, during the operation of the foaming machine, the above operations can be repeated to put new raw materials into the feeding box for pre-mixing. When the foaming machine has finished foaming and a new foaming operation is needed, one end of the conveying hose is connected to the preset and fixed receiving interface on the foaming barrel, and the discharge valve is opened to allow the raw materials in the feeding box to enter the foaming barrel along the conveying hose, and the foaming machine will then foam the raw materials.

[0036] Meanwhile, the delivery hose 26 is detachable and can be disassembled for maintenance or cleaning after a period of use. When the delivery hose 26 needs to be disassembled, the magnetic positioning plug 4 is removed and the movable clip 33 is rotated until its sliding groove is aligned with the guide block 252 of its corresponding insertion hole and inserted. The above operation is repeated in sequence, and then the delivery hose can be disassembled.

[0037] After maintenance or cleaning, align the mounting part 3 of the delivery hose 26 with the insertion hole and insert it. Then move the movable clamp 33 away from the fixed block 31 until it is above the flange part 2, and rotate it until the sliding groove 2 of the movable clamp 33 is intersected with the guide block 252 of the insertion hole. Then insert the magnetic positioning plug 4 into the magnetic groove 253, and before insertion, ensure that its limiting plug 41 is aligned with the sliding groove 2 of its movable clamp 33.

[0038] In this invention, the sponge raw material can be premixed by the feeding mechanism and the premixed raw material is transported to the foaming barrel of the foaming machine. When the foaming machine is running, the feeding mechanism can independently premix the next batch of raw material. When feeding the material to the feeding mechanism, the height of the feeding component can be adjusted according to the user's own needs.

[0039] 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.
