[0001] The utility model relates to mechanical shaft technical field, especially relates to a glue film mechanical shaft for glue film packaging. BACKGROUND

[0002] The glue film of the photovoltaic module plays a key role in the packaging link of the photovoltaic module, and the main role is to protect the battery piece and package it into the photovoltaic module that can output direct current.

[0003] The existing photovoltaic glue film is usually covered by an automatic laying machine when packaging the photovoltaic module, and the glue film mechanical shaft of the automatic laying machine is used to drive the glue film paper tube to rotate so as to release more glue film.

[0004] But in the implementation process of the above technical scheme, it is found that at least the following technical problems exist: different sizes of photovoltaic modules have different requirements for glue film, so the inner diameter of the glue film paper tube has a certain deviation, so the glue film mechanical shaft is difficult to keep in contact with the inner wall of the paper tube during use, which can easily lead to the glue film being unable to package the photovoltaic module flatly, resulting in a low product pass rate. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the utility model provides a glue film mechanical shaft for glue film packaging, which solves the technical problems that different sizes of photovoltaic modules have different requirements for glue film, so the inner diameter of the glue film paper tube has a certain deviation, so the glue film mechanical shaft is difficult to keep in contact with the inner wall of the paper tube during use, which can easily lead to the glue film being unable to package the photovoltaic module flatly, resulting in a low product pass rate.

[0006] To achieve the above purpose, the utility model realizes the following technical scheme:

[0007] A glue film mechanical shaft for glue film packaging, comprising a shaft body, a bidirectional threaded rod is rotatably installed in the inside of the shaft body, a threaded sleeve is screwedly installed on the bidirectional threaded rod, first supporting rods are uniformly rotatably installed on the threaded sleeve, a second supporting rod is rotatably installed on the shaft body, and a top plate is rotatably installed on the second supporting rod; the tail end of the first supporting rod is rotatably connected with the top plate.

[0008] Preferably, fixed rings are fixedly installed on the two ends of the bidirectional threaded rod.

[0009] Preferably, mounting seats are rotatably installed on the two ends of the bidirectional threaded rod.

[0010] Preferably, double-headed threaded rods are screwedly installed on the fixed rings.

[0011] Preferably, first rubber pads are fixedly installed on the two ends of the shaft body.

[0013] Preferably, mounting holes are uniformly arranged on the mounting base.

[0014] Preferably, the inner portion of the shaft body is fixedly mounted with a supporting ring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] I. When the bidirectional threaded rod and the mounting hole remain relatively stationary, the shaft body rotates in the positive direction to push the threaded sleeve to expand the top plate outward, and the shaft body rotates in the reverse direction to pull the threaded sleeve to shrink the top plate inward, so that the rubber film paper tube with different inner diameters can be clamped, and the product qualification rate is improved.

[0017] II. After the position of the top plate is adjusted, the bidirectional threaded rod is rotated counterclockwise (the right bidirectional threaded rod), and since the bidirectional threaded rod is threadedly connected with the fixed ring, the bidirectional threaded rod will slide to the left (the left bidirectional threaded rod is opposite), and when the side end of the bidirectional threaded rod abuts against the first rubber pad, the other side of the bidirectional threaded rod will be away from the second rubber pad, so that the bidirectional threaded rod can remain relatively stationary with the shaft body by the friction force of the bidirectional threaded rod abutting against the first rubber pad, and when the shaft body is rotated, the bidirectional threaded rod can rotate with the shaft body, so that the position of the top plate is not deviated during use, and the stability of the equipment is improved.

[0026] EMBODIMENT

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 indicated, the technical solution in the present application embodiment effectively solves the technical problem that different sizes of photovoltaic modules have different requirements for glue film, so that the inner diameter of the glue film paper tube has a certain deviation, so that the glue film mechanical shaft is difficult to adhere to the inner wall of the paper tube during use, which easily leads to the technical problem that the glue film cannot be flat and pack the photovoltaic module, resulting in lower product pass rate, and the overall idea is as follows:

[0028] In view of the problems in the prior art, the present application provides a kind of glue film mechanical shaft for glue film packaging, including shaft body 1, bidirectional threaded rod 2 is rotatably installed in the inside of shaft body 1, threaded sleeve 3 is screw mounted on bidirectional threaded rod 2, first support rod 4 is uniformly rotatably installed on threaded sleeve 3, second support rod 5 is rotatably installed on shaft body 1.

[0029] The second support rod 5 is rotatably connected with the top plate 6; the end of the first support rod 4 is rotatably connected with the top plate 6; the two ends of the bidirectional threaded rod 2 are symmetrically fixedly connected with the fixed ring 7; and the two ends of the bidirectional threaded rod 2 are symmetrically rotatably connected with the mounting seat 11.

[0030] The fixed ring 7 is uniformly screw-connected with the double-headed threaded rod 8; the two ends of the shaft body 1 are symmetrically fixedly connected with the first rubber pad 9; the side end of the mounting seat 11 is fixedly connected with the second rubber pad 13; the mounting seat 11 is uniformly provided with the mounting hole 12; and the inside of the shaft body 1 is fixedly connected with the support ring 14.

[0031] Working principle:

[0032] Firstly, the two mounting holes 12 are fixed by the second rubber pad 13 during installation; and the shaft body 1 is rotated under the driving of the transmission device during use; the double-headed threaded rod 8 is rotated clockwise (the right double-headed threaded rod 8); since the double-headed threaded rod 8 is screw-connected with the fixed ring 7, the double-headed threaded rod 8 will slide to the right (the left double-headed threaded rod 8 is opposite); when the side end of the double-headed threaded rod 8 abuts against the second rubber pad 13, the other side of the double-headed threaded rod 8 is away from the first rubber pad 9; at this time, the fixed ring 7 is kept relatively stationary with the mounting hole 12 by the friction of the double-headed threaded rod 8, that is, the bidirectional threaded rod 2 is kept relatively stationary with the mounting hole 12; at this time, the shaft body 1 is rotated; the shaft body 1 will drive the threaded sleeve 3 to rotate; since the threaded sleeve 3 is screw-connected with the bidirectional threaded rod 2, when the shaft body 1 is rotated, the threaded sleeve 3 will slide (the left threaded sleeve 3 slides to the right, and the right threaded sleeve 3 slides to the left); the sliding threaded sleeve 3 will lift the top plate 6 through the first support rod 4, so that the plurality of top plates 6 are simultaneously slid outward; at this time, the distance between the top plate 6 and the shaft center of the shaft body 1 will be increased, so that the top plate 6 can clamp the paper cylinder with a large inner diameter from the inside.

[0033] Secondly, when the shaft body 1 is reversed, the threaded sleeve 3 will slide (the left threaded sleeve 3 slides to the left, and the right threaded sleeve 3 slides to the right); the sliding threaded sleeve 3 will pull back the top plate 6 downward through the first support rod 4, so that the plurality of top plates 6 are simultaneously slid inward; at this time, the distance between the top plate 6 and the shaft center of the shaft body 1 will be decreased, so that the top plate 6 can clamp the paper cylinder with a small inner diameter from the inside; when the position of the top plate 6 is adjusted, the double-headed threaded rod 8 is rotated counterclockwise (the right double-headed threaded rod 8); since the double-headed threaded rod 8 is screw-connected with the fixed ring 7, the double-headed threaded rod 8 will slide to the left (the left double-headed threaded rod 8 is opposite); when the side end of the double-headed threaded rod 8 abuts against the first rubber pad 9, the other side of the double-headed threaded rod 8 is away from the second rubber pad 13, so that the bidirectional threaded rod 2 can keep relatively stationary with the shaft body 1 by the friction of the double-headed threaded rod 8 abutting against the first rubber pad 9, so that the bidirectional threaded rod 2 can rotate with the shaft body 1 when the shaft body 1 is rotated.

[0034] Finally, it should be noted that: apparently, the above examples are merely for the purpose of clearly illustrating the utility model, and not limited to the implementation. For those of ordinary skill in the art, on the basis of the above description can also be made other different forms of changes or variations. Here do not need to and can not all the implementation to be exhausted. The obvious changes or variations derived from still within the scope of the utility model.
