All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0034] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a cotton loosening device for a sofa cotton filling machine, comprising:

[0035] The loose cotton chassis 1 is provided with a loose cotton mechanism. It should be noted that the sofa cotton is loosened by the loose cotton mechanism, and the sofa cotton wrapped around the loose cotton stick 4 is automatically cleaned without manual removal and cleaning, which is convenient to use.

[0036] The cotton loosening mechanism includes a power motor 2, a hollow roller 3, a cotton loosening stick 4, a connecting rod 5, a connecting plate 6, an inner column 7 and a spring 8;

[0037] The power motor 2 is fixedly installed on the front side of the cotton loosening machine chassis 1, the output end of the power motor 2 is fixedly connected to the hollow roller 3, the inner column 7 is fixedly installed inside the hollow roller 3, the spring 8 is fixedly installed between the inner column 7 and the connecting plate 6, and the cotton loosening rod 4 and the connecting rod 5 are both fixedly installed on the connecting plate 6.

[0038] By using the above-mentioned loosening mechanism, the two power motors 2 are started, the two hollow rollers 3 rotate in opposite directions, and the hollow rollers 3 drive the loosening stick 4 to rotate, so that the loosening stick 4 loosens the sofa cotton.

[0039] Specifically, the cotton loosening mechanism also includes an electric telescopic rod 9 and a push block 10. The electric telescopic rod 9 is fixedly installed on the side of the cotton loosening machine chassis 1. The telescopic end of the electric telescopic rod 9 is fixedly connected to the push block 10. Circular grooves are provided on both side walls of the cotton loosening machine chassis 1, and the push block 10 is located in the circular grooves.

[0040] Through the above-mentioned cotton loosening mechanism, when more cotton is wound on the cotton loosening swab 4, the power motor 2 is started to align a connecting rod 5 with the pushing block 10, and then the electric telescopic rod 9 is started, and the pushing block 10 moves into the second slide hole to push the connecting rod 5, so that the end of the cotton loosening swab 4 moves into the interior of the first slide hole. During this process, the hollow roller 3 can block the cotton wound on the cotton loosening swab 4, so that the cotton wound on the cotton loosening swab 4 falls off, and then the pushing block 10 returns to its position, and the power motor 2 is started to align an adjacent connecting rod 5 with the pushing block 10, and the above steps are repeated until the cotton wrapped around all the cotton loosening swabs 4 is cleaned.

[0041] Specifically, a connecting pipe 11 is fixedly provided on the cotton loosening machine chassis 1, a sofa cotton filling machine body 12 is fixedly provided on the connecting pipe 11, a fan 13 and a cotton outlet pipe 14 are fixedly provided on the sofa cotton filling machine body 12, and a supporting platform is fixedly provided at the bottom of the sofa cotton filling machine body 12. It should be noted that the loosened cotton is sucked into the cotton filling machine body 12 by the fan 13, and then the cotton is sprayed out through the cotton outlet pipe 14 to fill the sofa. The specific structure of the sofa cotton filling machine body 12 is the existing technology and will not be elaborated here.

[0042] Specifically, a cotton inlet pipe 15 is fixedly provided on the top of the cotton loosening machine chassis 1 , and a valve 16 is installed on the cotton inlet pipe 15 . It should be noted that this is for the convenience of adding cotton into the cotton loosening machine chassis 1 .

[0043] Specifically, the connecting plate 6 contacts the inner wall of the hollow roller 3 . It should be noted that the connecting plate 6 is subjected to a position limiting process.

[0044] Specifically, a plurality of sliding holes 1 are opened on the outside of the hollow roller 3, and the cotton loosening swab 4 is slidably installed in the sliding hole 1. A plurality of sliding holes 2 are opened on the outside of the hollow roller 3, and the connecting rod 5 is slidably installed in the sliding hole 2. The end of the connecting rod 5 is located in the sliding hole 2. It should be noted that this makes it convenient for the cotton loosening swab 4 and the connecting rod 5 to slide on the hollow roller 3.

[0045] Working principle:

[0046] S1: Start the two power motors 2, and the two hollow rollers 3 rotate in opposite directions. The hollow rollers 3 drive the loosening sticks 4 to rotate, so that the loosening sticks 4 loosen the sofa cotton. The loosened cotton is sucked into the cotton filling machine body 12 by the fan 13, and then the cotton is ejected through the cotton outlet pipe 14 to fill the sofa;

[0047] S2: When there is more cotton wrapped around the cotton loosening swab 4, the power motor 2 is started, so that a connecting rod 5 is aligned with the pushing block 10, and then the electric telescopic rod 9 is started. The electric telescopic rod 9 drives the pushing block 10 to move, and the pushing block 10 moves into the second slide hole to push the connecting rod 5, and the connecting rod 5 drives the connecting plate 6 to move. The connecting plate 6 squeezes the spring 8 and drives the cotton loosening swab 4 to move, so that the end of the cotton loosening swab 4 moves into the interior of the first slide hole. In this process, the hollow roller 3 can block the cotton wrapped around the cotton loosening swab 4, so that the cotton wrapped around the cotton loosening swab 4 falls off;

[0048] S3: The pushing block 10 returns to its position and the power motor 2 is started to align an adjacent connecting rod 5 with the pushing block 10. The above steps are repeated until the cotton wrapped around all the loose cotton swabs 4 is cleaned. This facilitates automatic cleaning of the sofa cotton wrapped around the loose cotton swabs 4 and does not require manual removal for cleaning, making it more convenient to use.

[0049] The above describes in detail the loosening device for a sofa filling machine provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention.
