Description

Technical Field

[0001] The utility model relates to the technical field of cocoon processing, in particular to an automatic cocoon peeling device. Background Art

[0002] In current cocoon peeling machines, whether they are used by enterprises or inspection institutions, especially notarial inspection institutions, public inspection institutions generally only remove the cocoon floss from standard samples (5 kg) to calculate the cocoon floss rate. The amount of cocoon floss generally ranges from 60 g to 100 g depending on the differences in the cocooning tools. Moreover, it is required that the cocoon floss of the sample must be completely removed to ensure the accuracy of the cocoon floss rate.

[0003] The cocoon peeling machines used by notarial inspection institutions are relatively small, and the cocoon floss wound on the peeling belt cannot be too thick, otherwise it is easy to cause jams. Especially for cocoons with a relatively large cocoon floss rate and a little thin skin, it is even easier to cause jams, and it is also troublesome to handle. Manually removing the cocoon floss has low efficiency, is not easy to remove completely, will have a certain impact on the cocoon floss rate, and there will be certain potential safety hazards during peeling.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 to 5 , an automatic cocoon stripping device provided by the present invention: includes a rotating shaft 4, two ends of the rotating shaft 4 are each rotatably connected to a mounting block 1, two sides of the two mounting blocks 1 horizontally penetrate two mirror-symmetric first countersunk holes 2, the outer edge of the rotating shaft 4 is radially fixed with a plurality of equally spaced and axially distributed stripping rake racks 5, the tooth heads of the stripping rake racks 5 are polished smoothly and are in a bullet shape, both ends of the rotating shaft 4 are each provided with a backstop, each backstop is movably connected to a mounting block 1, and each of the outer sides of the two mounting blocks 1 is provided with a limiting member connected to the rotating shaft 4;

[0022] The backstop includes an arc-shaped block 13 fixed at the end of the rotating shaft 4, the arc-shaped block 13 is concentric with the rotating shaft 4, an arc-shaped groove 14 adapted to the arc-shaped block 13 is horizontally opened on the inner side of the mounting block 1, the arc-shaped block 13 is movably connected in the arc-shaped groove 14, a second spring 15 is jointly fixed between the arc-shaped block 13 and the arc-shaped groove 14, the cross-section of the arc-shaped groove 14 is a dovetail-shaped groove, and the cross-section of the arc-shaped block 13 is a dovetail shape adapted thereto;

[0023] The limiting member includes a support plate 8 fixed on the outer edge of the rotating shaft 4, a blind hole 9 is horizontally opened on the outer side of the support plate 8, a support block 7 is fixedly connected to the outside of the mounting block 1, an insert block 6 adapted to the blind hole 9 is movably connected in the support block 7, a second countersunk hole 11 is horizontally penetrated through the inner side of the support block 7, a pull rod 10 is axially slidably inserted through the second countersunk hole 11, one end of the pull rod 10 is fixedly connected to a pulling block 3, the pulling block 3 abuts against the outside of the support block 7, the insert block 6 is fixedly connected to the other end of the pull rod 10, and a first spring 12 is sleeved on the outer edge of the pull rod 10, and the first spring 12 abuts between the insert block 6 and the second countersunk hole 11.

[0024] By movably connecting the rotating shaft 4 between two mounting blocks 1 by means of a check member and fixing a plurality of equally spaced stripping rake racks 5 on the rotating shaft 4, the cocoon floss and the slightly thin-skinned cocoons wound on the cocoon stripping belt are stripped. On the one hand, it prevents the cocoon floss wound on the cocoon stripping belt from being too thick, which is likely to cause jamming, so that the rotating shaft 4 can automatically rotate according to the thickness of the cocoon floss wound on the cocoon stripping belt, and automatically adjust the angle of the stripping rake rack 5, so that the stripping rake rack always contacts the cocoon floss. On the other hand, it solves the problems of low efficiency of manually removing cocoon floss, not being easy to remove cleanly, and there being certain safety hazards during manual stripping, and improves the accuracy of cocoon stripping efficiency and cocoon floss rate.

[0025] Working principle: When in use, the automatic stripping device is connected to the cocoon stripping machine of the external public inspection agency through the mounting block 1 by bolts and the first countersunk holes 2, so that the rounded tooth heads of the stripping rake racks 5 are tangent to the cocoon floss on the cocoon stripping belt. When cocoon stripping is required, the stripping rake racks 5 will automatically turn backward according to the thickness of the cocoon floss on the cocoon stripping belt. The arc-shaped block 13 moves in the arc-shaped groove 14 in the mounting block 1, and at the same time squeezes the second spring 15 to be compressed. When the second spring 15 is compressed, it exerts a reverse thrust, so that the stripping rake racks 5 always fit the cocoon floss on the cocoon stripping belt. When not in use, the rotating shaft 4 is rotated backward so that the support block 7 is aligned with the support plate 8. At the same time, the pulling block 3 is pulled outward. The pulling block 3 retracts the inserting block 6 into the second countersunk hole 11 through the pull rod 10. At the same time, the first spring 12 is compressed, so that the blind hole 9 is aligned with the second countersunk hole 11. Then the pulling block 3 is released, and the compressed first spring 12 is reset. When the first spring 12 is reset, it pushes the inserting block 6 out of the second countersunk hole 11, so that the inserting block 6 is inserted into the blind hole 9, so that the stripping rake racks 5 are separated from the cocoon floss on the cocoon stripping belt. At the same time, the arc-shaped block 13 moves in the arc-shaped groove 14, and the second spring 15 is compressed.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
