AI Technical Summary
During the backwashing process of existing sponge foaming feeders, wastewater can easily remain in the pipe between the feed inlet outlet and the valve, causing pollution and affecting the foaming quality.
A sponge foaming feeder head including a guide column and a solenoid valve was designed. The guide column can move longitudinally in the mixing chamber, block the outlet of the feed pipe, and guide the material to mix through the shrink section, ensuring that sewage does not enter the feed pipe during the backwashing process. The material is folded back in the shrink section to improve the mixing uniformity.
It effectively avoids contamination at the die head, ensures the purity of the material and the stability of the foaming quality, and improves the uniformity of material mixing before the die head.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to sponge processing technical field relates to a convenient reverse washing's sponge foaming feeding machine head. BACKGROUND
[0002] The raw material of sponge foaming is sent into the foaming box through the machine head, and different raw materials are required for different performance sponges, so the residual material in the machine head needs to be cleaned before the machine head is used again, the existing machine head includes a plurality of material inlet connecting pipes and a mixing chamber located in the machine head and connected to each connecting pipe, when reverse washing is needed, each connecting pipe is closed, then reverse washing liquid is sent from the material outlet end of the machine head, and the waste water after reverse washing is discharged from the reverse washing outlet pipe on the machine head, since there is a certain distance between the valve of the material inlet connecting pipe and the outlet of the material inlet connecting pipe, the waste water generated by reverse washing can be stored in the pipeline between the outlet of the material inlet connecting pipe and the valve, causing the machine head to need to be first discharged when it is used again, in addition, the waste water in the pipeline is fouled, which affects the purity of the material to some extent, and affects the foaming quality and the stability of the product parameters. SUMMARY
[0003] The utility model discloses in order to solve the above -mentioned technical problems that exist in the prior art, provide a convenient reverse washing's sponge foaming feeding machine head, and the technical problem that the utility model wants to solve is how to avoid the pollution of the machine head caused by reverse washing.
[0004] The utility model discloses the purpose can be realized through the following technical scheme: a convenient reverse washing's sponge foaming feeding machine head, characterized by including the body, the mixing chamber in the body, a plurality of material inlet pipes connected with the mixing chamber, a blowdown pipe connected with the mixing chamber and a guide column longitudinally slidingly connected in the mixing chamber, the blowdown pipe is located below the material inlet pipe, and the guide column can move downward in the mixing chamber to block the outlet of each material inlet pipe.
[0005] Further, the guide column is controlled by an electromagnetic valve, and the electromagnetic valve can control the longitudinal movement of the guide column in the mixing chamber.
[0006] Further, the guide column includes a closing part capable of blocking the outlet of the material inlet pipe and a contraction part located below the closing part, and the middle part of the contraction part has a smaller diameter than the diameters of the two ends of the contraction part.
[0007] The present scheme can ensure that all positions of the inlet pipes are isolated from the mixing chamber during backwashing by closing the outlets of the inlet pipes with the guide column, so that sewage generated during backwashing cannot enter the inlet pipes. In addition, the middle part of the guide column is provided with a contraction part, which can guide the material in the inlet pipes into the mixing chamber and mix the materials of the inlet pipes entering the mixing chamber. This is because the space is larger when the material enters the middle part of the contraction part, ensuring that the materials discharged from the inlet pipes contact each other. The space gradually decreases as the material continues to descend, increasing the discharge pressure of the material at this position. The material will also produce a turnaround when flowing to the discharge position of the head, and multiple material turnarounds can improve the flow of materials relative to each other, ensuring efficient and uniform mixing before discharging from the head.

[0009] In the figure, 1, the body; 2, the mixing chamber; 3, the inlet pipe; 4, the guide column; 41, the closed part; 42, the contraction part; 5, the electromagnetic valve; 6, the sewage pipe. DETAILED DESCRIPTION
[0010] The following is a specific embodiment of the present application combined with the drawings, which further describes the technical scheme of the present application. However, the present application is not limited to these embodiments.
[0011] As shown in Figure 1 The sponge foaming feeder head includes a body 1, a mixing chamber 2 located in the body 1, a plurality of inlet pipes 3 connected to the mixing chamber 2, a sewage pipe 6 connected to the mixing chamber 2, and a guide column 4 longitudinally slidingly connected in the mixing chamber 2. The sewage pipe 6 is located below the inlet pipe 3, and the guide column 4 can move downward in the mixing chamber 2 to block the outlets of the inlet pipes 3. The guide column 4 is controlled by an electromagnetic valve 5, and the electromagnetic valve 5 can control the longitudinal movement of the guide column 4 in the mixing chamber 2. The guide column 4 includes a closed part 41 that can block the outlets of the inlet pipes 3 and a contraction part 42 located below the closed part 41. The middle part of the contraction part 42 has a smaller diameter than the two ends of the contraction part 42.
[0012] The present scheme can ensure that all positions of the feeding pipes 3 are isolated from the mixing cavity 2 during the backwashing process by closing the outlets of the feeding pipes 3 through the guide columns 4 when backwashing is needed, so that the sewage produced by the backwashing cannot enter the feeding pipes 3. In addition, a contraction part 42 is arranged in the middle of the guide column 4. The contraction part 42 can guide the materials in the feeding pipes 3 to enter the mixing cavity 2 and mix the materials entering the mixing cavity 2 from the feeding pipes 3. This is because the space is large when the materials enter the middle of the contraction part 42, which ensures that the materials discharged from the feeding pipes 3 contact each other. The space gradually decreases when the materials continue to descend, so that the pressure of the materials discharged at this position increases. The materials flow to the discharge position of the machine head again, which can improve the mutual flow of the materials and ensure that the materials are efficiently and uniformly mixed before being discharged from the machine head.
[0013] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
