Description

Technical Field

[0001] The utility model relates to the technical field of brush wire cutting for shield machines, in particular to a brush wire continuous cutting device for shield machines. Background Art

[0002] The shield tail brush is mainly composed of three parts, including a protective plate made of steel plate material, a pressing plate and a wire brush made of stainless steel. The wire brush is installed between the protective plate and the pressing plate. The protective plate, the pressing plate and the wire brush are fixed to the base plate of the shield tail through pins. Since the shape of the wire brush is generally a broken line or a wave shape in its length direction, the smooth and flat steel wire needs to be pressed to a certain extent and then cut into small sections of a certain length to meet the length requirements of the steel wire.

[0003] The brush wire bundle is usually composed of several strands of brush wire, so multiple pay-off mechanisms are required to pay out the wires at the same time before cutting and bundling, and compaction is required before bundling and plying, so as to facilitate the subsequent continuous cutting and processing of the bundled brush wire bundle. In the existing equipment, it is not convenient to install a single brush wire pay-off wheel and a bracket to replace the pay-off wheel as a whole after the pay-off is completed; and when the brush wires before bundling and plying are compacted and limited, it is not convenient to quickly release the compaction so as to compact the new brush wires, and the overall disassembly and compaction efficiency needs to be improved.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1The utility model provides a technical solution: a shield machine brush wire continuous cutting device, comprising a support frame 1, a workbench 8 with a cutting assembly 18, and a plurality of pay-off wheels 5 rotatably connected to the support frame 1 through a rotating shaft 4, a notch 2 is arranged on the upper part of the support frame 1, bearings are installed at the ends near both ends of the rotating shaft 4, and the bearings are placed in the notch 2. A limit plate 3 is arranged on one side of the support frame 1, and the bearings cannot move along the axial direction of the rotating shaft 4 under the limiting effect of the limit plate 3 (the inability to move here refers to the inability to move outside the gap within the installation tolerance range); a screw thread between the pay-off wheel 5 and the rotating shaft 4 The workbench 8 is connected in a threaded manner, with two locking pieces 7 being threadedly connected to the rotating shaft 4, and a number of pay-off wheels 5 are limitedly fixed between the two locking pieces 7; a guide base 9 is fixedly provided at the edge of the upper end surface of the workbench 8, and a number of guide grooves 10 are penetrated through the guide base 9, and a clamping plate 13 is rotatably connected to the guide base 9 through a connecting seat 11, and a clamping protrusion 14 matching the guide groove 10 is provided on the lower end surface of the clamping plate 13, and a clamping plate 15 is symmetrically arranged on the clamping plate 13, and the clamping plate 13 is fixed to the guide base 9 by the clamping plate 15; a number of clustering tubes 17 are arranged on the workbench 8 between the cutting assembly 18 and the guide base 9.

[0023] The utility model, through the U-shaped groove and the limit plate 3, after the brush wire on the pay-off wheel 5 is paid off, the rotating shaft 4 can be lifted upward as a whole, so as to separate the support frame 1 from the rotation, and then the rotating shaft 4 loaded with another brush wire pay-off wheel 5 is limited and placed in the U-shaped groove, so as to improve the overall cutting efficiency. When the whole device is in a working state, the pay-off wheel 5 on the disassembled rotating shaft can be replaced with a pay-off wheel 5 loaded with brush wire, and can be fixed by the locking member 7 in conjunction with the thread on the rotating shaft 4, and the overall disassembly and assembly efficiency is high. Through the provided clamping plate 15 and the connecting seat 11, when it is necessary to release the clamping limit of the brush wire, the clamping relationship between the clamping plate 15 and the guide base 9 can be released, and then the clamping plate 13 can be quickly flipped to open the guide groove 10. After the new brush wire bundle is put into the guide groove 10 again, the clamping protrusion 14 on the clamping plate 13 can be used again through the clamping plate 15 to clamp and limit the brush wire bundle in the guide groove 10, and the overall replacement efficiency is high.

[0024] Reference Figure 1 and 3 As shown, in this embodiment, a compression spring 6 is provided between the locking member 7 and the outermost pay-off wheel 5, and the compression spring 6 is sleeved on the rotating shaft 4. Under the action of the compression spring 6, the threaded connection between the two locking members 7, the plurality of pay-off wheels 5 and the rotating shaft 4 can be subjected to the elastic pre-tightening force of the compression spring 6, thereby improving the stability of the locking member 7 and the pay-off wheel 5 installed with the rotating shaft 4, so that the pay-off wheel 5 can stably rotate with the rotating shaft 4 during the subsequent cutting process.

[0025] Reference Figure 3 As shown, in this embodiment, the locking member 7 includes a locking sleeve 71 threadedly connected to the rotating shaft 4, and the outer surface of the locking sleeve 71 is evenly distributed with a plurality of protrusions 73 in an annular shape, and a polygonal sleeve 72 is provided on one side of the locking sleeve 71. A person can manually hold the protrusion 73, thereby locking the locking sleeve 71 to lock the extrusion spring 6 and the pay-off wheel 5; at the same time, the polygonal sleeve 72 can be screwed with the help of a tool to complete the installation of the locking sleeve 71. By providing two locking methods on the locking sleeve 71, it is convenient for a person to select a suitable installation method to tighten the locking sleeve 71 according to actual application needs, which is conducive to improving the locking installation efficiency of the pay-off wheel 5.

[0026] In this embodiment, a connecting portion 12 is disposed on the pressing plate 13 , and the connecting portion 12 is rotatably connected to the connecting seat 11 .

[0027] Reference Figure 4 As shown, in this embodiment, a push plate 16 is integrally formed on the clamping plate 15, and the clamping plate 15 can be elastically deformed by squeezing the push plate 16, thereby releasing the clamping fixation between the clamping plate 13 and the guide base 9. When the clamping plate 13 needs to be adjusted and opened, it is only necessary to push the push plate 16 to elastically deform the clamping plate 15, so that the lower part of the clamping plate 15 is no longer clamped with the guide base 9, so that the clamping plate 13 can be rotated to open, and personnel can put a new brush bundle into the guide groove 10. The overall replacement and clamping process only requires manual operation by personnel, which is convenient and quick.

[0028] Reference Figure 4 As shown, in this embodiment, a bent portion is provided at one end of the clamping plate 15 away from the clamping plate 13, and the open direction of the bent portion faces the guide base 9. When the lower portion of the clamping plate 15 is clamped and fixed with the guide base 9, due to the bent portion provided on the clamping plate 15, the rounded corner of the bent portion first contacts the end surface of the guide base 9. Therefore, when a person pushes the pushing plate 16 to elastically deform the clamping plate 15, under the action of the elastic force, the bent plate and the lower portion of the clamping plate 15 can be smoothly clamped and fixed with the lower end surface of the guide base 9, thereby completing the clamping fixation of the clamping plate 13.
