Description

Technical Field

[0001] The utility model belongs to the technical field of foaming equipment, in particular to a foaming equipment for producing automobile seat foam. Background Art

[0002] The production of automotive seat foam mainly uses polyurethane foaming equipment, including low-pressure foaming machines and high-pressure foaming machines. The high-pressure foaming machine sends components A and B into the mixing head of the high-pressure pouring head through a high-pressure pump. After rapid mixing under high pressure, the components are poured into the mold for foaming and molding.

[0003] At present, in actual application of existing high-pressure foaming machines, it is found that the two materials are mixed inside the mixing head, and the mixing is promoted by external pressure alone. The time is short and it cannot ensure that the materials are fully mixed. It is easy to cause foam voids that affect product quality and the nozzle is easily blocked, which is not conducive to the normal foaming operation of the equipment.

[0004] In order to solve the above problems, this application proposes a foaming device for producing automobile seat foam. Utility Model Content

[0005] The purpose of the utility model is to provide a foaming device for producing automobile seat foam, which solves the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a foaming device for producing automobile seat foam, comprising: a foaming machine and a mixing head and a nozzle below the mixing head; a mixing tube is provided between the mixing head and the nozzle, and the injected material is stirred by a built-in inner ring frame and stirring blades therein to promote fusion, and a filter screen for protecting the stirring blades is provided on the inner side of the inner ring frame near the upper and lower ends; a micro-rotating motor is provided inside the mixing tube, and the adapter shaft at the lower end of the mixing tube engages with the convex teeth at the upper end of the outer ring frame to drive the mixing tube to rotate; the mixing tube is a structure with upper and lower relative structures, and an annular space is formed by the inner and outer layer structures for installing the micro-rotating motor and its adjacent components.

[0008] Furthermore, bosses connected to the mixing tubes are provided below the mixing head and above the nozzle, and opposite surfaces of adjacent mixing tubes are provided with protruding plate mechanisms to form a butt connection.

[0009] Furthermore, a transfer block is provided on the outer side of the inner ring frame and docked with the outer ring frame, and is rotatably installed inside the limiting groove between the inner layer structures of adjacent mixing tubes.

[0010] Furthermore, a toothed structure meshing with the convex teeth is provided on the outer side of the adapter shaft.

[0011] Furthermore, a protruding cam is provided at the lower end of the adapter shaft, and a positioning shaft seat for rotatably mounting the cam is provided inside the upper part of the mixing tube below.

[0012] Furthermore, the connection between the convex shaft and the positioning shaft seat is used to position the rotation axis of the adapter shaft to form a limit to prevent it from swinging significantly.

[0013] Furthermore, the opposite ends of adjacent mixing tubes respectively belong to sealing gasket mechanisms that press against the mixing head and the inner wall of the nozzle to form a seal.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can add a mixing tube so that the two materials can be stirred by the stirring blades immediately when entering, so as to promote the fusion of the two materials and ensure that there are no voids in the foam, which can effectively avoid the occurrence of uneven mixing, thereby ensuring the quality of the foamed product and improving the practical performance of the equipment;

[0016] In addition, by utilizing the upper and lower relative structures of the mixing tube, an adapter shaft can be directly installed inside and the inner ring frame can be driven to rotate through the adapter shaft to achieve the effect of real-time mixing of materials. While being convenient to use, it can be taken out at any time to connect to the water spray mechanism to clean the internal components, reducing the difficulty of equipment maintenance and improving the use effect.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A micro-rotating motor 13 is provided inside the mixing tube 4, which engages with the convex teeth 12 on the upper end of the outer ring frame 9 through the adapter shaft 14 at its lower end to drive its rotation. The mixing tube 4 has an upper and lower relative structure, and the inner and outer layers form an annular space for installing the micro-rotating motor 13 and its adjacent components.

[0030] This embodiment provides a high foaming device that can promote secondary mixing of materials. By adding a mixing tube 4, the incoming material can be stirred through the internal components, so that the adjacent materials are subjected to a secondary mixing process to remove the voids inside the foam and ensure the subsequent foaming quality of the product. In addition, the mechanism is easy to assemble and disassemble and the internal components can be taken out at any time for cleaning and maintenance. It is simple to operate and convenient to use.
