Description

Technical Field

[0002] A foaming machine is a mechanical device used to make foam materials. It uses physical or chemical methods to expand liquid or mixture to form foam. It is used to produce different types of foam products, including soft polyurethane foaming machines, hard polyurethane foaming machines, etc. Among them, soft polyurethane foaming machines make polyurethane foam by mixing isocyanate and polyol and other additives such as catalysts, surfactants, foaming agents, etc. Soft polyurethane foam is widely used in furniture, mattresses, car seats, sound insulation materials and other fields due to its good flexibility and comfort.

[0003] In the existing patent CN216968456U, a foaming machine capable of improving foaming efficiency is disclosed. The foaming machine capable of improving foaming efficiency includes a foaming tank body, a feeding pipe for feeding into the foaming tank body is fixedly connected to the foaming tank body, an air inlet hole is opened on the top of the foaming tank body, and an air inlet pipe is fixedly connected to the inner wall of the air inlet hole. By arranging the cooperation of the foaming tank body, the air inlet hole, the air inlet pipe, the conduit, the air diffusion pipe, the stirring rod and the driving device, steam is discharged from the air diffusion hole on the air diffusion pipe along the air inlet pipe and the conduit at the bottom of the foaming tank body, and at the same time, the driving device is started to drive the conduit to rotate, and the rotation of the conduit drives the air diffusion pipe and the stirring rod to rotate. The air diffusion pipe rotates to blow out the steam evenly, and the stirring rod rotates to stir the foam material in the foaming tank body, thereby improving the heating uniformity of the foam particles, avoiding insufficient foaming of the foam particles that sink to the bottom, thereby reducing the foaming time and improving the foaming uniformity.

[0044] Working principle: During normal operation, the foam raw material is introduced into the foam barrel 1 through the feed port 2, so that the foam raw material fills the foam barrel 1. During stirring, the motor 501 is started, and the output shaft of the motor 501 rotates to drive the rotating rod 502 to rotate, and the rotating rod 502 rotates to drive the clamping rod 603 to rotate. Under the action of the convex rod 604 and the groove 602, the clamping rod 603 rotates to drive the sleeve 601 to rotate, and the sleeve 601 rotates to drive the rotating sealing plate 403 to rotate. The sleeve 601 rotates to drive the supporting ear 801 to rotate, and the supporting ear 801 drives the stirring rod 1 802 and the stirring rod 2 803 to rotate. The last stirring rod 2 803 drives another supporting ear 801 to rotate, and at the same time, The support ear 801 drives the sleeve 703 and the annular scraper 704 to rotate, so that the stirring rod 1 802 and the stirring rod 2 803 stir the foam raw material, and at the same time, the rotating sealing plate 403 drives the lower connecting rod 1102 to rotate synchronously, and the lower connecting rod 1102 drives the rotating ring 702 to rotate. Since the upper connecting rod 1101 and the lower connecting rod 1102 are formed as one body, the lower connecting rod 1102 drives the upper connecting rod 1101 to move, so that the lower connecting rod 1102 and the upper connecting rod 1101 synchronously drive the connecting inner tube 1103 and the connecting outer tube 1104 to rotate synchronously, so that the lower air supply ring tube 1003 rotates on the upper air supply ring tube 1002, and the effect of rotation and stirring is achieved;

[0045] During air intake and stirring, in the above stirring process, the air pump 1001 is started, and the air pump 1001 introduces gas into the connecting inner tube 1103 and the connecting outer tube 1104 through the action of the upper air supply ring tube 1002 and the lower air supply ring tube 1003, and introduces gas into the air intake block 1201 through the action of the air intake pipe 1203 and the air distribution pipe 1204, and the gas is guided out to the surroundings of the foam raw material through the air intake hole 1202, so that the gas is dispersed to various positions of the foaming barrel 1, so that every place in the foaming barrel 1 is filled with gas, achieving the effect of uniform foaming, thereby forming the effect of air intake and stirring, and improving the uniform effect of foaming. When the foaming is completed, the discharge port 3 is opened to release the foam for utilization;

[0046] Since the amount of foam raw materials discharged each time is different, when adjustment is needed, the electric push rod 901 is started, and the output end of the electric push rod 901 drives the support ring 902 to move upward or downward to a reasonable position. Taking the upward movement as an example, the upward movement of the support ring 902 drives the upper air supply ring tube 1002 and the lower air supply ring tube 1003 to move upward, so that the upper connecting rod 1101 and the lower connecting rod 1102 move upward. At the same time, under the connection action of the screws and nuts, the connecting inner tube 1103 and the connecting outer tube 1104 move upward, and the lower connecting rod 1102 drives the rotating ring 702 to move upward, so that the rotating ring 702 drives the supporting plate 701 to move upward, and the supporting plate 701 drives the sleeve 703 and the annular The scraper 704 moves upward. Since the position of the sleeve 601 does not change, and the sleeve 703 moves upward, the stirring rod 1 802 and the stirring rod 2 803 will shrink, reducing the space occupied by the stirring rod 1 802 and the stirring rod 2 803. At the same time, the air intake block 1201 moves to a reasonable position with the corresponding stirring rod 1 802 and the stirring rod 2 803. According to the above steps during normal operation, the foam raw material is air-intake-stirred, further achieving the foaming effect of the foam raw material, forcing different amounts of foam raw materials to be allocated to different working spaces in the foaming barrel 1, so that the stirring rod 1 802 and the stirring rod 2 803 shrink to different states, so that the device can adapt to different amounts of foam raw materials;

[0047] When disassembly is required, for example, when the foaming barrel 1 needs to be cleaned, the electric push rod 901 is started, so that the output end of the electric push rod 901 drives the support ring 902 to continuously move upward to the limit position, and the support ring 902 moves upward to drive the upper air supply ring tube 1002 and the lower air supply ring tube 1003 to move upward, so that the upper connecting rod 1101 and the lower connecting rod 1102 move upward, and at the same time, under the connection action of the screw and the nut, the connecting inner tube 1103 and the connecting outer tube 1104 move upward, and the lower connecting rod 1102 drives the rotating ring 702 to move upward, so that the rotating ring 702 drives the supporting plate 701 to move upward, and the supporting plate 701 drives the sleeve 703 and the annular scraper 704 to move upward, so that the stirring rod 1 802 and the stirring rod 2 803 will shrink to the maximum state;

[0048] The nut is rotated to disengage the screw from the nut, and the electric push rod 901 is continued to be started to move the support ring 902 up to a reasonable position. At the same time, the upper connecting rod 1101 is separated from the lower connecting rod 1102, and the connecting inner tube 1103 is separated from the connecting outer tube 1104. The sealing ring 401 and the rotating sealing plate 403, the sleeve 601, the stirring rod 1 802, the stirring rod 2 803, the sleeve 703, the annular scraper 704, the rotating ring 702, and the supporting plate 701 are removed manually or by equipment to disengage the insertion rod 402 from the foaming barrel 1. Under the action of the protruding rod 604 and the groove 602, the sleeve 601 is disengaged from the clamping rod 603, thereby completing the disassembly of the device. During the disassembly process, the annular scraper 704 can clean the residual foam material on the rotating rod 502, and the supporting plate 701 can clean the residual foam material on the inner wall of the foaming barrel 1, thereby improving the cleaning effect.

[0049] The setting of the sealing component 4 can achieve a sealing effect on the foaming barrel 1, avoid overflow when the foam raw material is stirred by air intake, and improve the rationality of the device.
