[0003] For example, a full-automatic foam production machine with publication number CN222178318U relates to the technical field of foam production equipment and comprises a support frame, a stirring tank and a raw material tank. The top of the support frame is fixedly provided with the stirring tank, and the bottom of the support frame is provided with the raw material tank at both ends. The top of each of the two raw material tanks is fixedly provided with a first water pump, and the side of each of the two first water pumps is fixedly provided with a conveying pipeline. The other end of each of the two conveying pipelines is fixedly connected with the support plate and the side surface of the stirring tank. The top of one end of each of the two raw material tanks is fixedly provided with a liquid level detector, and the side of each of the two raw material tanks is provided with a liquid level meter.

[0004] For example, a raw material auxiliary proportioning device for irradiation cross-linking polyethylene foam production with publication number CN118596448A relates to the field of foam production devices. To solve the problem that in the prior art, when polyethylene foam starts to melt, mixing and extrusion production are needed, and the existing proportioning mode mostly mixes and stirs after manual weighing, the production efficiency is slow.

[0037] The auxiliary self-adjusting structure is arranged between the butt joint connecting part 6 and the reservation base 1, and is used for adjusting the transmission rate of the butt joint conductor 3.

[0038] The auxiliary self-adjusting structure is provided with an external butt joint disc 7, which is arranged outside the butt joint connector 6. The upper end surface of the reserved base body 1 is fixedly connected with a reset spring assembly 9, and the upper end of the reset spring assembly 9 is in contact with the lower end of the external butt joint disc 7. The outer side of the external butt joint disc 7 is fixedly connected with a contact support 10, and the contact support 10 corresponds to the outer side of the wedge-shaped butt joint 17.
