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 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 panels, and the winding braces 2 are connected to each other through an expansion and contraction mechanism 3. The rotary shaft 1 is connected; the expansion and contraction mechanism 3 includes a base 31 fixed on the rotary shaft 1 , and a second shaft that is hinged to the base 31 and rotates axially relative to the rotary shaft 1 and is arranged parallel to each other. A connecting plate 32 and a second connecting plate 33, the ends of the first connecting plate 32 and the second connecting plate 33 away from the rotary shaft 1 are hingedly arranged with the winding brace 2, and the expansion and contraction mechanism 3 adjusts the first connecting plate 32 , The angle between the second connecting plate 33 and the base 31 realizes expansion and contraction; when the steel reel ne...

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 steel reel, which comprises a rotary shaft and a plurality of winding braces arranged around the rotary shaft in the circumferential direction for winding sound-absorbing plates, and the winding braces are connected to the rotary shaft through an expansion and contraction mechanism. connection; the expanding and contracting mechanism includes a base fixed on the rotating shaft, and a first connecting plate and a second connecting plate that are hinged to the base and rotate axially relative to the rotating shaft and are arranged parallel to each other. The ends of the first connecting plate and the second connecting plate far away from the rotary shaft are hingedly arranged with the winding support plate, and the expansion and contraction mechanism realizes expansion and contraction by adjusting the angle between the first connecting plate, the second connecting plate and the base. The invention can realize the contraction and expansion of the steel reel, and at the same time, the plate has a self-blocking function during winding, so that the plate is less slack during winding and is not easy to disperse, and the plate can be effectively clamped after the winding is completed.

Description

technical field [0001] The invention relates to a steel reel for automobile sound-absorbing plates, and more specifically relates to a 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 steel reel, which can realize the contraction and expansion of the steel reel. At the same time, the plate h...
