Problems solved by technology

[0002] The steel reel is a necessary part for winding automobile sound-absorbing panels. The applicant found that the existing steel reels are generally fixed in size and cannot be adjusted in size, and occupy a large area. Correspondingly, the usable area of ​​the entire workshop is reduced.
[0003] At the same time, the applicant also found that during the process of winding the sound-absorbing plate on the steel drum, the winding is not tight, and the winding is loose, which increases the risk. If the binding is not tight, or the binding material is scratched and broken by the plate, the binding effect is poor

Embodiment

[0025] Example: such as Figure 1-Figure 3 As shown, a new type of steel reel includes a rotary shaft 1, a plurality of winding braces 2 arranged around the rotary shaft 1 and used for winding sound-absorbing plates, and the winding braces 2 pass through the expansion and contraction mechanism 3 Connected with the rotary shaft 1; the expansion mechanism 3 includes a base 31 fixed on the rotary shaft 1, and hinged with the base 31, which rotate axially relative to the rotary shaft 1 and are arranged parallel to each other. The first connecting lever 32 and the second connecting lever 33, the ends of the first connecting lever 32 and the second connecting lever 33 away from the rotary shaft 1 are hingedly arranged with the winding support plate 2, and the expansion and contraction mechanism 3 adjusts the first connecting lever 32. The angle between the second connecting lever 33 and the base 31 realizes expansion and contraction; when the steel reel needs to be contracted, manua...

Embodiment 2

[0036] Embodiment 2: as Figure 4 As shown, the clamping part 552 is a cylindrical body, the surface of the cylindrical body is vertically provided with a plurality of linearly arranged elastic pressure columns 5521, and the end surface of the elastic pressure columns 5521 is provided with a spherical groove 5522, and the grooves 5522 is provided with a rollable spherical indenter 5523. The spherical pressure head 5522 adjusts the contact point during rolling, and the elastic pressure column 5521 reduces the rigid impact during clamping, reduces the deformation of the board, and effectively protects the board.

Abstract

The invention discloses a novel steel reel, includes a rotary axis, and a plurality of winding brackets which are installed along the rotary axis and is used to wind the silence board. The winding brackets are linked with the rotary axis by the expansion mechanism which consists of the base fixed on the rotary axis, the first linking board and the second linking board. The first linking board is in parallel with the second linking board and both of them are hinged together with the base. The first linking board and the second linking board can turn axially by choosing the rotary axis as the reference. The ends, of which the first and second linking boards are far from one end of the rotary axis, are hinged with the winding brackets. The function of the expansion system can be fulfilled by adjusting the angle between the first linking board and the second linking board. The contract and the expansion of the steel reel can be achieved by this invention. While winding, the board has the self blocking function which will lessen the loosing degree of the board and make the roll of the board hard to unfix. After winding process, the self blocking function can also fasten the board effectively.

Description

technical field [0001] The invention relates to a steel reel for automobile sound-absorbing plates, and more specifically relates to a new type of steel reel. Background technique [0002] The steel reel is a necessary part for winding automobile sound-absorbing panels. The applicant found that the existing steel reels are generally fixed in size and cannot be adjusted in size, and occupy a large area. Correspondingly, the usable area of ​​the entire workshop is reduced. [0003] At the same time, the applicant also found that during the process of winding the sound-absorbing plate on the steel drum, the winding is not tight, and the winding is loose, which increases the risk. If the binding is not tight, or the binding material is scratched and cut by the plate, the binding effect is poor. Contents of the invention [0004] The purpose of the present invention is to provide a new type of steel reel, which can realize the shrinkage and expansion of the steel reel. At the ...
