Description

Technical Field

[0001] The present invention belongs to the technical field of cultural relic mural cutting equipment, and particularly relates to a wire feeding structure for a mural masonry stripping device. Background Art

[0002] Ancient murals refer to paintings directly drawn on walls, usually appearing on the walls of grottoes, tombs or important buildings. They are important materials reflecting ancient society, life, art, etc., and are also witnesses of ancient Chinese civilization. Here, it mainly refers to paintings drawn by painters on the surfaces of ancient tombs or rocks with certain historical and archaeological value. Exquisite murals are generally from noble tombs. However, there are a large amount of soil, water and microorganisms in ancient tombs, which will all have a destructive impact on the murals. How to extract precious murals from the tomb passage intact is a great challenge for cultural relic protection personnel. Currently, murals are usually cut into pieces manually, otherwise they will break, which determines that there will inevitably be damage during mural cutting, resulting in irreparable consequences. Moreover, manual operation has large errors and requires relatively high experience and physical strength, and manual cutting is bound to damage the murals.

[0003] So far, there is no automated or semi-automated equipment that can be referred to in the mural stripping industry. It is a completely new technical blank for the mural industry, and it can only be integrated through a series of calculations and designs through a large number of attempts, tests and verifications; select a suitable cutting and stripping method according to the different cutting media and the mixture, structure of the media itself, as well as the connection characteristics between them;

[0004] Existing cutting equipment on the market can all be used for conductive materials. During the cutting process, coolant and cutting fluid are added, and the cutting speed can be adjusted according to the magnitude of the current and the different materials to be cut. However, murals are non-conductive, cannot be cooled with water, and cannot vibrate;

[0005] The present invention proposes a brand-new wire feeding structure to ensure that vibration and noise are maintained at a minimum during the cutting process, and damage to the murals is reduced as much as possible. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a wire feeding structure for a mural masonry stripping device.

[0028] Such as Figure 1-2A wire feeding structure for a mural masonry stripping device as shown, including a wire rotating assembly, a wire guiding wheel assembly, and a wire cutting assembly. The wire rotating assembly includes a front-back shifting member, wire 1, a wire feeding shaft 2, and a wire feeding servo motor 3. The wire cutting assembly includes a first rod 4 and a second rod 5 arranged in parallel and a wire guiding wheel 6. The parallel arrangement of the first rod 4 and the second rod 5 can effectively reduce the rotational inertia and avoid vibration as much as possible.

[0029] The wire feeding shaft 2 is installed on the front-back shifting member. One end of the wire feeding shaft 2 is connected to the wire feeding servo motor 3. The wire 1 is wound around the wire shaft 2. One end of the first rod 4 and one end of the second rod 5 are both connected to the bottom of the front-back shifting member, and the other ends of both are provided with wire guiding wheels 6. The wire 1 is wound around the wire feeding shaft 2, and one end of it extends out of the wire feeding shaft 2 and forms a winding path through the wire guiding wheel assembly and the two wire guiding wheels 6.

[0030] The wire 1 serves as a tool for cutting the mural masonry.

[0031] Specifically, it further includes a synchronous belt 7, a first synchronous belt pulley 8, a second synchronous belt pulley 9, a synchronous belt pulley servo motor 10, and a wire arranging lead screw 11. The wire arranging lead screw 11 is arranged on the front-back shifting member. One end of the wire feeding shaft 2 away from the wire feeding servo motor 3 is connected to the first synchronous belt pulley 8. One end of the wire arranging lead screw 11 is connected to the second synchronous belt pulley 9, and the other end is connected to the synchronous belt pulley servo motor 10. The synchronous belt 7 is sleeved on the first synchronous belt pulley 8 and the second synchronous belt pulley 9.

[0032] The function of wire arranging is achieved by the forward and reverse rotation of the wire feeding servo motor 3. Specifically, when the wire feeding servo motor 3 rotates forward, the wire feeding shaft 2 starts to wind the wire forward, and the wire arranging lead screw 11 drives the whole to move forward. When it moves to the front extreme limit position of the wire feeding shaft 2, the wire feeding servo motor 3 rotates in reverse and retreats, and the wire arranging lead screw 11 drives the whole to move backward. When it moves to the rear extreme limit position of the wire feeding shaft 2, the wire feeding servo motor 3 rotates forward. The wire arranging part keeps performing such reciprocating motions. The whole movement process is only completed by the forward and reverse rotation of the wire feeding servo motor 3, and it is ensured that the wires do not overlap during the wire arranging process.

[0033] Specifically, the front-back shifting member includes a base 12, a sliding plate 13, and a linear guide rail 14. The linear guide rail 14 is installed on the base 12. The sliding plate 13 is installed at the bottom of the wire feeding shaft 2. The sliding plate 13 is slidably matched with the linear guide rail 14. The bottom of the base 12 is connected to one end of the first rod 4 and the second rod 5 arranged in parallel away from the wire guiding wheel 6.

[0034] Specifically, the wire guide wheel assembly includes a first wire guide wheel 15, a second wire guide wheel 16, a third wire guide wheel 17, and a fourth wire guide wheel 18. The first wire guide wheel 15 and the second wire guide wheel 16 are arranged on both sides of the wire transporting shaft 2, and the central axes of the first wire guide wheel 15 and the second wire guide wheel 16 are parallel to each other. The third wire guide wheel 17 and the fourth wire guide wheel 18 are oppositely arranged on both sides of the wire transporting shaft 2, and the central axes of the third wire guide wheel 17 and the fourth wire guide wheel 18 are both perpendicular to the central axes of the first wire guide wheel 15 and the second wire guide wheel 16, so that the wire can be smoothly transitioned to facilitate the adjustment of the wire tension.

[0035] Specifically, the wire 1 is wound around the wire transporting shaft 2 and one end thereof extends out of the wire transporting shaft 2 and sequentially passes through the first wire guide wheel 15, the fourth wire guide wheel 18, two wire guide wheels 6, the third wire guide wheel 17, and the second wire guide wheel 16 to form a closed loop.

[0036] Specifically, it further includes a tension adjuster 19 connected to the first wire guide wheel 15. The tension of the wire 1 is adjusted through the wire guide wheel assembly.

[0037] Specifically, the tooth number ratio of the first synchronous pulley 8 and the second synchronous pulley 9 is 2:5, and the synchronous effect is optimal at this ratio.

[0038] Specifically, it further includes a handle 20 installed on one side of the base 12. The function of the handle 20 is to facilitate the assembly of the wire structure onto the mural masonry stripping device.

[0039] Working principle:

[0040] The wire cutting part moves (i.e., the position where the wire 1 is located between the two wire guide wheels 6), so as to ensure that the non-cut part is cooled by air. The wire arranging function is mainly achieved by the forward and reverse rotation of the wire transporting servo motor 3. The entire movement process is only completed by the forward and reverse rotation of the wire transporting servo motor 3, and it is ensured that the wires do not overlap during the wire arranging process;

[0041] At the same time, the wire tension is adjusted through the wire guide wheel assembly during the reciprocating movement of the wire.

[0042] In summary, a device applicable to the cutting of complex media such as mural masonry is developed, filling the gap in the lack of automated machinery for the stripping and repair of mural supports in masonry murals in cultural relics, and greatly reducing the damage to cultural relics during mural excavation.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.

[0044] Many other changes and modifications can be made without departing from the spirit and scope of the present invention. It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
