DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are involved in the protection scope of the utility model.

[0022] Reference Figures 1-5 A sponge foaming machine, comprising a shell 1, the top of the shell 1 is provided with a liquid inlet 101, the bottom of the shell 1 is provided with a liquid outlet 102, further comprising a stirring mechanism, the stirring mechanism comprises a rotating motor 2 arranged at the top of the shell 1, a stirring rod 201 arranged in the shell 1 and rotating plates 202 respectively fixedly connected with both sides of the stirring rod 201, the stirring rod 201 as a whole can be designed in a cylindrical shape, and the stirring rod 201 is rotationally connected with the rotating plates 202, the surface of the cylindrical stirring rod 201 is smooth and simple, compared with the stirring tool with complex geometric shape, it can rotate more stably in the solution, reducing fluid resistance. Reducing resistance helps to reduce motor power consumption, and can make the stirring process more efficient.

[0023] Further, the output end of the rotary motor 2 extends to the inside of the shell 1 and is fixedly connected with the rotating plate 202, the opposite side of the two rotating plates 202 is fixedly connected with the air supply cylinder 203, the outer surface of the air supply cylinder 203 is provided with a plurality of air outlet hard pipes 204, each air outlet hard pipe 204 is in communication with the inside of the air supply cylinder 203, each air outlet hard pipe 204 is provided with an air outlet channel 205, the air outlet hard pipe 204 is connected with an air supply mechanism, the top of the shell 1 is provided with a fixed plate 6, the rotary motor 2 is fixedly connected with the fixed plate 6 through bolts, and the rotary motor 2 and the fixed plate 6 are fixed to prevent self-rotation during operation, thereby ensuring the stability during work.

[0024] In use, the staff injects the foaming solution into the inside of the shell 1 through the liquid inlet 101, starts the rotary motor 2 and the air supply mechanism. The output end of the rotary motor 2 drives the rotating plate 202 to rotate, and the rotating plate 202 in turn drives the stirring rod 201 to stir the foaming solution. At the same time, the air supply mechanism continuously injects air into the air supply pipe 301, and injects the gas into the inside of the solution through the air outlet channel on the air outlet hard pipe 204, thereby avoiding the gas staying on the surface of the solution, ensuring that it is more deeply distributed in the entire solution, and improving the foaming effect. In addition, the air outlet hard pipe 204 will rotate under the action of the air supply cylinder 203, and disturb the solution, further enhancing the mixing effect.

[0025] Specifically, the air supply mechanism includes a blower 3 and an air supply pipe 301, the inside bottom of the shell 1 is provided with a rotating column 302, the rotating plate 202 is rotationally connected with the rotating column 302, the rotating column 302 and the air supply cylinder 203 are on the same axis, and the output end of the rotary motor 2 can also be on the same horizontal plane with the rotating column 302 and the air supply cylinder 203, the inside of the rotating column 302 and the air supply cylinder 203 is provided with an air supply channel 303, one end of the air supply pipe 301 is in communication with the inside of the air supply channel 303, and the other end of the air supply pipe 301 is connected with the blower 3. When the rotating plate 202 rotates under the action of the rotary motor 2, the rotating plate 202 will drive the air supply cylinder 203 to rotate, and the stirring rod 201 will rotate around the air supply cylinder 203, and the other rotating plate 202 will rotate around the rotating column 302 under the action of the air supply cylinder 203 and the stirring rod 201, thereby preventing the air supply cylinder 203 from driving the air supply pipe 301 to rotate.

[0026] In use, the air blower 3 will continuously input stable air flow to the air supply pipe 301 after the staff starts the air blower 3, and the air supply pipe 301 will deliver the air to the air supply channel 303, so that the air enters the inside of the solution through the air outlets of the air hard pipes 204. The selection of the air blower 3 can ensure the uniformity of air input, avoid the unevenness of foam or quality fluctuation caused by unstable air flow (it should be noted that when the gas flows into the inside of the shell 1 through the air outlet channel 205 under normal operation, a certain flow rate and pressure are usually maintained, and the density difference between the liquid and the gas makes it difficult for the liquid to enter the inside of the air supply cylinder 203 through the air outlet channel 205 under normal circumstances, so the solution is difficult to enter the inside of the air supply channel 303 through the air outlet channel 205 under normal operation), and after the foaming solution is mixed, the staff can open the liquid outlet 102 to discharge the foaming solution in the inside of the shell 1.

[0027] In the embodiment, in order to prevent the solution from entering the inside of the air supply pipe 301 through the air outlet channel 205 when the staff pours the prepared foaming solution into the inside of the shell 1, a sealing mechanism for sealing the air outlet channel 205 is arranged at the end of each air hard pipe 204 away from the air supply cylinder 203, and the sealing mechanism comprises a sealing ball 4, an elastic sheet 401 (the elastic sheet 401 can also be replaced by a spring), and a support plate 402. An annular inclined surface 2051 is arranged at the side of the air outlet channel 205 away from the air supply cylinder 203, and the inner diameter of the annular inclined surface 2051 gradually increases from the air outlet pipe to the side away from the air supply cylinder 203. The support plate 402 is arranged at the side of the annular inclined surface 2051 away from the air supply cylinder 203 and is fixedly connected with the air hard pipe 204. One end of the elastic sheet 401 is fixedly connected with the support plate 402, and the other end of the elastic sheet 401 is fixedly connected with the sealing ball 4. The sealing ball 4 abuts against the surface of the annular inclined surface 2051. It should be noted that the width of the support plate 402 and the elastic member is smaller than the inner diameter of the air outlet channel 205, and a plurality of through holes are arranged on the support plate 402 to ensure that the air can be discharged through the gap between the support plate 402 and the air outlet channel 205.

[0028] By arranging the sealing mechanism, when the air blower 3 is not in use, the sealing ball 4 is always in contact with the annular inclined surface 2051 under the action of the elastic sheet 401, so as to close the air outlet channel 205 and prevent the solution from entering the inside of the air supply cylinder 203 through the air outlet channel 205 when not in use, thereby reducing the risk of blockage of the air supply pipe 301 and ensuring the reliability and stability of the air hard pipe 204 and the air supply mechanism in long-term use (it should be noted that when the air blower 3 is working, the air blower 3 has enough pressure to push the sealing ball 4 to compress the elastic sheet 401).

[0029] In the embodiment, the cleaning mechanism is connected to one side of the air supply pipe 301, and comprises a water storage tank 5, a water delivery pump 501 (water suction pump), and a water delivery pipe 502. One end of the water delivery pipe 502 is arranged at one side of the air supply pipe 301 and communicates with the inside of the air supply pipe 301, and the other end of the water delivery pipe 502 is connected to one end of the water delivery pump 501, and the other end of the water delivery pump 501 communicates with the inside of the water storage tank 5.

[0030] By arranging the cleaning mechanism, after the foaming solution is mixed, the staff can discharge the solution through the liquid outlet 102 and start the cleaning mechanism to clean the inside of the shell 1, so as to prevent the residual solution of the previous batch from reacting with the raw materials of the next batch, thereby ensuring the stability of the quality of each batch of sponge products.

[0031] In use, the staff starts the water delivery pump 501, the water delivery pump 501 sucks out the water in the water storage tank 5 and delivers the solution to the inside of the air supply pipe 301 through the water delivery pipe 502. The solution enters each air outlet channel 205 through the air supply channel 303, pushes the sealing ball 4 to compress the elastic sheet 401, thereby opening the air outlet channel 205, the solution is sprayed out through the air outlet channel 205, thereby completing the flushing of the inside of the shell 1, and the cleaned solution can also be discharged through the liquid outlet. At the same time, the staff can also start the rotating motor 2 to make the air supply cylinder 203 drive the air outlet hard pipe 204 to rotate, thereby improving the cleaning range. It should be noted that after the cleaning is completed, the staff can start the air blower 3 to discharge the residual water in the air supply pipe 301, the air supply cylinder 203 and the air outlet hard pipe 204, so as to avoid that the residual water dilutes the foaming solution of the next batch, thereby further ensuring the stability of the quality of the sponge products.

[0032] In order to prevent the water suction pump from delivering the solution to the inside of the air blower 3, a first stop valve 503 is arranged on the water delivery pipe 502, and a second stop valve 504 is arranged on one side of the air supply pipe 301 close to the air blower 3, and the second stop valve 504 is arranged on the side of the air supply pipe 301 away from the water delivery pipe 502.

[0033] When the cleaning mechanism works, the staff closes the second stop valve 504 and opens the first stop valve 503, so that the solution sucked out by the water suction pump will not be delivered to the inside of the air blower 3; when the air supply mechanism works, the first stop valve 503 is closed and the second stop valve 504 is opened, the air blower 3 delivers air to the inside of the air supply channel 303 through the air supply pipe 301, but will not enter the water suction pump through the water delivery pipe 502, thereby ensuring the stability of the air pressure.

[0034] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
