[0002] The foamed sponge production equipment is mainly used for producing sponge products, including household items such as mattresses, seat cushions, sofa cushions, pillows, and industrial sponges. These devices mix chemical raw materials through specific processes and technologies, inject them into molds or other containers, and then foam them by means of heating, pressurization, etc. to form the required sponge-like substances. When mixing chemical raw materials, a stirring device is often used for mixing. And in some cases, the raw materials need to be heated during the stirring process, mainly to promote the mixing and reaction between the raw materials and improve the foaming effect.

This heating method can only heat the mixed materials close to the barrel wall. Usually, the heating efficiency is low, and it takes a long time to achieve an effective heating effect. Moreover, the mixed materials in the barrel are heated very unevenly, which will affect the mixing and foaming effect. Therefore, a foamed sponge production equipment is proposed to solve the above problems. Summary of the Utility Model

Detailed implementation manners
[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:
[0032] As Figure 1 - Figure 2 shown, a foamed sponge production device provided in this embodiment includes a stirring barrel 1, on which a barrel cover 2 is provided, a hollow rotating shaft 3, which is rotatably arranged in the stirring barrel 1, and on which a main heating and stirring rack 41 and an auxiliary heating and stirring rack 42 are installed, a rotating contact power supply mechanism 6, which is used to supply power for the operation of the main heating and stirring rack 41 and the auxiliary heating and stirring rack 42, and a driving mechanism 7, which is used to drive the hollow rotating shaft 3 to rotate.

[0033] To realize the power supply for the main heating and stirring rack 41 and the auxiliary heating and stirring rack 42, as Figure 5As shown in the figure, the rotating contact power supply mechanism 6 includes two contact rings 62 provided at the top of the hollow rotating shaft 3 and electrically connected to the main heating and stirring frame 41 and the auxiliary heating and stirring frame 42, and two power supply brushes 64 in electrical contact with the contact rings 62. An external power cord 65 is electrically connected to the power supply brush 64. The contact rings 62 and the power supply brushes 64 in the rotating contact power supply mechanism 6 work together to transmit electrical energy in a sliding contact manner without interfering with the rotation of the hollow rotating shaft 3.
[0034] As Figure 3 shown in the figure, the main heating and stirring frame 41 and the auxiliary heating and stirring frame 42 have exactly the same structure, both including a heat-conducting outer shell 401. An electric heater 402 is provided in the heat-conducting outer shell 401. A wire 403 is electrically connected to the electric heater 402. Through the above structural form, heat can be continuously generated by the energized operation of the electric heater 402, and the mixed material in contact can be heated through the heat-conducting outer shell 401, which is the basis for the heating function of the entire device.
[0035] Among them, the heating pipes of the electric heater 402 are laid along the direction of the heat-conducting outer shell 401, and the gap between the heat-conducting outer shell 401 and the electric heater 402 is filled with heat-conducting glue. Through the above structural form, it can be ensured that as much space as possible in the heat-conducting outer shell 401 is distributed with the heat-generating electric heater 402. At the same time, the heat-conducting glue can fill the gap between the heat-conducting outer shell 401 and the electric heater 402, improving the heat release efficiency of the electric heater 402.
[0036] In addition, the wire 403 is laid upward along the hollow rotating shaft 3. Among them, all the wires 403 connected to the positive pole are electrically connected to the same contact ring 62, and all the wires 403 connected to the negative pole are electrically connected to the other contact ring 62.

A fixed seat 63 is provided on the barrel cover 2. Both power supply brushes 64 are embedded in the fixed seat 63. Among them, both the sleeve 61 and the fixed seat 63 are made of insulating materials. Through the above structural form, the contact rings 62 and the power supply brushes 64 can be fixedly installed while insulating them, avoiding short circuits or electric shocks caused by contact with metal structures.
[0038] As Figure 4As shown in the figure, a centrally arranged mounting cover cylinder 21 is fixedly provided on the lower end surface of the bucket cover 2. Two fixed bearings 22 are fixedly installed in the mounting cover cylinder 21. Among them, the inner ring of the fixed bearing 22 is fixedly connected to the hollow rotating shaft 3. Through the above structural form, the rotational connection between the hollow rotating shaft 3 and the bucket cover 2 can be realized, while fixing the position of the hollow rotating shaft 3 without affecting its rotation.
[0039] As Figure 4 shown in the figure, the hollow rotating shaft 3 includes a motor bracket 71 fixedly provided on the bucket cover 2. A driving motor 72 is installed on the motor bracket 71, and the output shaft of the driving motor 72 is fixedly connected to the top end of the hollow rotating shaft 3. Through the above structural form, the driving motor 72 can be used to drive the hollow rotating shaft 3 to rotate, and then drive the main heating stirring frame 41 and the auxiliary heating stirring frame 42 fixedly connected to the hollow rotating shaft 3 to rotate, so as to stir and mix the mixture.
[0040] As Figure 2 shown in the figure, a number of material turning paddles 5 are provided on the hollow rotating shaft 3. Among them, the material turning paddle 5 is composed of a collar sleeved on the hollow rotating shaft 3 and a number of blades fixedly connected to the collar. Through the above structural form, when the hollow rotating shaft 3 rotates, the material turning paddle 5 will be driven to rotate synchronously, so as to turn up some of the mixture close to it, which can further improve the mixing efficiency.

[0042] With the main heating stirring frame 41 and the auxiliary heating stirring frame 42 that can be energized and heated, the mixture can be heated from the inside while being stirred, which has high heating efficiency and heating uniformity. And the main heating stirring frame 41 and the auxiliary heating stirring frame 42 are of different sizes, and can heat the mixtures at different positions simultaneously, further improving the heating uniformity. The specific principle is that the electric heater 402 arranged inside generates heat continuously through energization, and heats the contacted mixture through the heat-conducting outer shell 401.
[0043] At the same time, the combination of the contact ring 62 and the power supply brush 64 in the rotating contact power supply mechanism 6 works to realize the transmission of electric energy in a sliding contact manner, which will not interfere with the rotation of the hollow rotating shaft 3, and the input electric energy can be transmitted to the electric heater 402 through the wire 403 electrically connected to the contact ring 62 to make it energized and heated.
[0044] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
