Description

Technical Field

[0001] This utility model belongs to the technical field of rewinding machine equipment, and in particular relates to a paper rewinding machine discharge mechanism. Background Technology

[0002] Rewinders are key supporting equipment after paper machines in the papermaking industry. They are mainly used to process large-diameter paper rolls produced by paper machines into finished paper rolls that meet the standards of downstream use. Paper roll rewinders are used to break down large-diameter paper rolls into smaller rolls that meet the requirements of paper roll products.

[0003] Generally, roll paper products need to be unloaded from the winding bar of the rewinding machine. The conventional method is to disassemble the bearing housing at one end of the winding bar to allow the roll paper product nested on the winding bar to be separated from one side of the winding bar. The bearing housing structure needs to be designed as a detachable structure to serve as the unloading mechanism of the roll paper rewinding machine. The current unloading mechanism of roll paper rewinding machines has a complex structure during the disassembly process. The bearing housing needs to complete sliding and deflection actions, so a complex locking structure is required to limit the bearing housing. The complex locking structure leads to insufficient loading and unloading efficiency, which is not conducive to the unloading operation of the product. Utility Model Content

[0023] This utility model embodiment provides a paper rewinding machine discharge mechanism, utilizing the end frame side plate 102 and the winding rod 101 of the rewinding machine, such as... Figures 1-9 As shown, the discharge mechanism of the paper rewinder includes: The base unit 200 includes a base 210 and limiting brackets 220 extending from both sides of the base 210. The flip shaft 300 includes a sliding seat 310 and an assembly shaft 320 rotatably connected to the sliding seat. The base 210 has a sliding cavity 201 for accommodating the sliding of the sliding seat 310, and the end of the sliding cavity 201 has a locking base block 230 for limiting the deflection of the assembly shaft 320. The base 210 can be fixed to the side plate 102 of the frame by bolts or welding. The assembly shaft 320 is an extension... The side plate 102 of the extended frame serves as the fixing structure for the other end of the winding rod 101. Here, the mounting bearing 320 is mainly set at the center for assembling the winding rod 101. The end of the winding rod 101 is provided with a corresponding tenon structure. The bearing is engaged and fixed with the end of the winding rod 101. The mounting bearing 320 is deflected perpendicular to the sliding seat 310. The winding rod 101 is inserted into the bearing seat. When discharging the product, the paper rewinding machine discharge mechanism at the end of the winding rod 101 is removed, and the drum nested on the paper roll of the winding rod 101 is moved out from one end of the winding rod 101. The assembly and fixing unit 400 includes a main frame 410 and wing clips 440 disposed at both ends of the main frame 410. The wing clips 440 are engaged with the base 210. The main frame 410 is also provided with a first embedding block 420 and a second embedding block 430. When the assembly bearing 320 is deflected perpendicular to the sliding seat 310, the first embedding block 420 and the second embedding block 430 are respectively embedded in the base 210 and the sliding seat 310.

[0024] In this embodiment, a sliding cavity 201 is provided in the base 210 to help the flipping shaft 300 achieve sliding movement. First, the flipping shaft 300 can release the nested assembly of the assembly shaft 320 and the winding rod 101 under the sliding movement. Then, the assembly shaft 320 is deflected so that it does not interfere with the product on the winding rod 101. This application uses the assembly fixing unit 400 in conjunction with the locking base block 230 to simultaneously limit the deflection and sliding movement of the assembly shaft 320. The assembly fixing unit 400 simultaneously achieves the purpose of double locking, which simplifies the assembly of the assembly components and improves the assembly efficiency of the equipment in the material discharge process. In a preferred embodiment of this invention, the side plate of the sliding cavity 201 is provided with a guide rail, the side plate of the sliding seat 310 is provided with a sliding groove 302 adapted to the guide rail, the locking base block 230 is disposed on one side of the sliding cavity 201, the sliding seat 310 slides to the end of the sliding cavity 201 near the base block 230, and the assembly fixing unit 400 is inserted into the gap formed by the sliding seat 310 and the sliding cavity 201. The sliding cavity 201 is provided with a first limiting groove 202 at one end away from the locking base block 230 to accommodate the insertion of the first embedding block 420. The sliding seat 310 is provided with a second limiting groove 301. When the assembly fixing unit 400 is inserted into the gap formed by the sliding seat 310 and the sliding cavity 201, the protrusion provided on the second embedding block 430 is inserted into the second limiting groove 301, while the first embedding block 420 is inserted into the first limiting groove 202. In this embodiment, the assembly fixing unit 400 simultaneously completes the insertion connection with the base unit 200 and the flipping shaft seat 300, while the locking base block 230 abuts against one side of the assembly shaft seat 320, and the second embedding block 430 abuts against the side of the assembly shaft seat 320 away from the locking base block 230, thus restricting the rotational deflection of the assembly shaft seat 320; at the same time, the first embedding block 420 penetrates the sliding cavity 201 and inserts into the first limiting groove 202 located at the bottom of the sliding cavity 201, and the portion of the first embedding block 420 embedded in the sliding cavity 201 prevents the sliding seat 310 from sliding; In a preferred embodiment of this invention, the wing card 440 has an L-shaped structure, and the wing card 440 and the main frame 410 form a locking groove. The locking groove engages with the side plate of the base 210 that forms the sliding cavity 201, and the limiting card seat 220 abuts against the wing card 440. In this embodiment, to enhance the structural strength of the assembly and fixing unit 400, the wing clip 440 is provided with screw holes, and the wing clip 440 is fixed to the base 210 by bolts; the bolts are used to enhance the connection and fixing effect between the assembly and fixing unit 400 and the base unit 200.

The mounting shaft seat 320 adopts an extended structure. When the mounting shaft seat 320 is deflected parallel to the base plate 311, it needs to be retracted to the frame side plate 102 to avoid the deflected mounting shaft seat 320 affecting the disassembly of the product on the winding rod 101.
