When the raw materials in the mixing barrel 2 need to be stirred, the motor 802 is first started, the motor 802 rotates the first rotating column 803, the first rotating column 803 drives the first umbrella wheel 804 and the stirring paddle 805 to rotate, and the stirring paddle 805 is used to stir the raw materials in the mixing barrel 2. The second bevel wheel 807 is driven to rotate, and the second bevel wheel 807 drives the transmission column 806 to rotate. The transmission column 806 rotates the second rotating column 809 through the differential 808, and adjusts the speed of the second rotating column 809 through the differential 808. Then the second rotating column 809 drives the sector gear 6 to rotate, and then the sector gear 6, the rack 9 and the spring 10 make the guide slider 5 reciprocate up and down. Then the guide slider 5 drives the stirring mechanism 8 to reciprocate up and down through the second support 7, so that the stirring paddle 805 reciprocates up and down in the inner cavity of the stirring barrel 2.

[0026] Working principle of the polyurethane foam preparation device for car seats:

[0027] When in use, first pour the raw materials into the mixing barrel 2, then start the motor 802, the motor 802 rotates the first rotating column 803, the first rotating column 803 drives the first umbrella wheel 804 and the stirring paddle 805 to rotate, and the stirring paddle 805 is used to stir the raw materials in the mixing barrel 2, and at the same time the first umbrella wheel 804 drives the second umbrella wheel 807 to rotate, the second umbrella wheel 807 drives the transmission column 806 to rotate, the transmission column 806 drives the second rotating column 809 to rotate through the differential 808, and the speed of the second rotating column 809 is adjusted through the differential 808, and then the second rotating column 809 drives the sector gear 6 to rotate, and the sector gear 6 is driven by the differential 808. The rack 9 moves downward, and the fan gear 6 drives the guide slider 5 to move downward through the second rotating column 809, and the spring 10 contracts. When the guide slider 5 moves a certain distance, the fan gear 6 and the rack 9 are no longer engaged, and then the spring 10 rebounds, causing the guide slider 5 to return to its original position, and then repeat the above operation to make the guide slider 5 reciprocate up and down. The guide slider 5 drives the stirring mechanism 8 to move through the second pillar 7, so that the stirring paddle 805 reciprocates up and down in the inner cavity of the stirring barrel 2. The stirring paddle 805 can be rotated and reciprocated up and down at the same time by a motor 802, saving the cost of the device.
