Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly mesh belt technology, specifically an environmentally friendly mesh belt for brazing furnaces. Background Technology

[0002] Brazing is a welding method that uses a metal with a lower melting point than the base metal as a filler metal. The liquid filler metal wets the base metal and fills the gap between the workpiece interface, allowing it to diffuse with the base metal. Brazing results in minimal deformation and smooth, aesthetically pleasing joints. It is suitable for welding precision, complex components made of different materials. A brazing furnace is a device used for metal brazing and bright heat treatment. It is suitable for mass production of small and medium-sized stainless steel parts (tableware, knives, hardware, etc.), such as bright quenching and tempering of martensitic stainless steel and bright annealing of austenitic stainless steel.

[0003] An environmentally friendly mesh belt brazing furnace, as disclosed in authorization announcement number CN212470109U, includes a brazing furnace body. Side plates are provided on both ends of the brazing furnace body. The interior of each side plate is connected to a first guide wheel and a second guide wheel via bearings. The interior of the other end of the brazing furnace body is connected to a third guide wheel via bearings. A limit wheel is connected to the inner bottom of the brazing furnace body via bearings. A mesh belt is also provided inside the brazing furnace body. Three horizontally arranged support plates are evenly arranged inside the brazing furnace body. Vertically arranged uprights are welded to the top of each support plate.

[0004] Although it achieves the connection of the first guide wheel and the second guide wheel through the side plate pivot, and the connection of the third guide wheel through the pivot at the other end, and the connection of two limit wheels to the bearing on the inner side of the bottom of the brazing furnace body, and the winding of the mesh belt on the outside, so that the mesh belt drives the component to continuously guide the component into the brazing furnace body to realize the brazing operation, when the component is guided to the top of the bending plate, the front part of the component will detach from the mesh belt and realize the brazing operation under the action of the lower nozzle. When the front part of the component is too heavy and is lowered, the rear part of the component will be lifted and realize the complete brazing operation under the action of the nozzle, which greatly improves the brazing effect of the contact part with the mesh belt.

[0005] However, this does not solve the problem that existing environmentally friendly mesh belts generally do not maintain stable dimensions and strength during use, affecting their service life, conveying stability, and making it difficult to move them back and forth for cleaning.

Multiple sets of first protrusions at equal intervals are provided on the surface of each rotating ring.

[0009] Preferably, the rotating ring surface near the first protrusion is provided with multiple sets of second protrusions at equal intervals. The first protrusions are all engaged with the first through hole, and the second protrusions are all engaged with the second through hole.

[0018] (1) Place the workpieces sequentially on the surface of the mesh belt body. The servo motor drives the rotating shaft to rotate, which in turn drives the synchronous belt pulley assembly to rotate. The synchronous belt pulley assembly drives the rotating shaft to rotate, which in turn drives the rotating frame, rotating ring, first protrusion, and second protrusion to rotate, thereby driving multiple sets of mesh belt strips to rotate, which in turn drives the mesh belt body to rotate, conveying the workpieces on the surface. The second roller and third roller play a role in smooth conveying. When passing one side of the brazing furnace body, the workpiece pushes the baffle into the interior of the brazing furnace body. When the baffle is separated from the workpiece, under the action of its own gravity, the baffle droops down and resets, protecting the interior of the brazing furnace body. When it is necessary to adjust the looseness of the mesh belt body... When tightening, turn the two sets of second nuts on both sides of the connecting plate. Under the threaded connection between the second nuts and the bolts, the two sets of second nuts move in opposite directions, causing the bolts to move left and right. The bolts drive the mesh belt body to move left and right through the first roller to tighten it. After tightening, tighten the second nuts on both sides of the connecting plate. Under the threaded connection between the second nuts and the bolts and the support of the connecting plate, the two sets of second nuts and the connecting plate come into contact, providing limit support for the bolts and fixing the mesh belt body. This ensures that the environmentally friendly mesh belt maintains stable dimensions and strength, avoiding accidents such as mesh belt deformation scraping the furnace body and jamming shutdown, increasing the service life of the environmentally friendly mesh belt, and improving the stability of the environmentally friendly mesh belt during transportation. (2) When it is necessary to blow clean the surface of the mesh belt body, connect the docking pipe to the external air supply device. The air is sprayed out through the docking pipe, adapter sleeve, hose, moving pipe and nozzle to clean the surface of the mesh belt body. When it is necessary to adjust the height up and down, the stepper motor drives the threaded rod to rotate, so that the threaded rod drives the threaded block to move up and down to the designated area for blowing and cleaning. When it is necessary to reciprocate and move for blowing and cleaning, the power motor drives the rotating disk to rotate, the rotating disk drives the support column to rotate, and the support column slides inside the connecting arm, so that the connecting arm drives the sector gear to reciprocate around the connecting column as the axis. Under the meshing of the sector gear and the rack, the sector gear drives the rack and nozzle to reciprocate and move for blowing and cleaning, realizing the convenient reciprocating movement of the environmentally friendly mesh belt for blowing and cleaning, reducing the labor intensity of manual labor and improving the efficiency of reciprocating movement of the environmentally friendly mesh belt for blowing and cleaning.

The surfaces of the bolts 42 on both sides of the connecting plate 40 are fitted with second nuts 41. The second nuts 41 and the first nuts 39 are threadedly connected to the bolts 42. When using an environmentally friendly brazing furnace mesh belt, the mesh belt body 5 is typically made of a high-performance heat-resistant alloy, which is much more expensive than ordinary stainless steel. However, the overall benefits brought by its long service life far outweigh the initial investment. Workpieces are placed sequentially on the surface of the mesh belt body 5. The servo motor 9 is turned on, and with the support of the frame 1, the servo motor 9 drives the rotating shaft 10 to rotate.

Air is sprayed out through docking pipe 28, adapter sleeve 4, hose 29, moving pipe 30, and nozzle 38 to clean the surface of mesh belt body 5. When it is necessary to adjust the height, stepper motor 23 drives threaded rod 24. The rotation causes the threaded rod 24 to move the threaded block 25 up and down to the designated area for cleaning. When reciprocating cleaning is required, the power motor 31 drives the rotating disk 32 to rotate, which in turn drives the support column 33 to rotate. The support column 33 slides inside the connecting arm 34, which in turn drives the sector gear 36 to reciprocate around the connecting column 35.
