Benefits of technology
This patented technology prevents leaks from gear frames used during welds or other types of work without adding extra components like lubricants or grease onto them. It achieves this through providing an internal oil-replacement layer inside the oil barrier and guiding rails of brackets. Additionally, it includes a special design where multiple oils have different properties but still perform their functions well together. Overall, these technical features improve the efficiency and quality of weld operations while reducing costs associated with maintenance efforts.
Problems solved by technology
This patented technical solution described for improving the lubrication system used with teeth frames in sewing machinery includes adding an oily substance called grease (often containing small particles) onto the outside of the teeth frame' s guiding rails beforehand. By doing these things, any excessive amounts of oil from previous steps may flow into areas around them without being washed away like dirt. Additionally, there could also be issues related to maintain cleanliness when attaching extra components - including thread reeling devices and materials like yarn bundles.

Embodiment Construction
[0023] refer to Figure 1 to Figure 3 The embodiment of the oil leakage prevention device for the tooth frame of the sewing machine of the present invention will be further described.
[0024] In the prior art bracket oil leakage prevention device, only an oil blocking mechanism is arranged on the outer side of the bracket, and there is only one oil prevention measure, and the oil prevention effect is poor. Therefore, the present invention designs two oil-proof mechanisms. The specific structure is as follows. An oil leakage prevention device for a sewing machine bracket 1 includes a bracket 1, a bracket guide 2, an oil baffle 3, and an oil seal 4. The oil seal 4 is assembled in the oil baffle 3, and the bracket 1 It is slidably fitted on the bracket rail 2, the bracket 1 runs through the oil seal 4, and also includes an inner oil-proof assembly 5, the bracket guide 2 is located on the inner side of the oil baffle 3, and the inner oil-proof assembly 5 is located on the inner sid

The invention discloses an oil leakage preventing device of a feet dog rack of a sewing machine. The oil leakage preventing device comprises a feet dog rack, a feet dog rack guide rail, an oil baffle and oil seal sheets. The oil seal sheets are assembled in the oil baffle. The feet dog rack slides on the feet dog rack guide rail in a matched mode. The feet dog rack penetrates through the oil seal sheets. The oil leakage preventing device further comprises an inner oil-proof assembly. The feet dog rack guide rail is located on the inner side of the oil baffle. The inner oil-proof assembly is located on the inner side of the feet dog rack guide rail. The feet dog rack penetrates through the inner oil-proof assembly. Two oil-proof measures are arranged on the feet dog rack, and compared with an existing single oil-proof measure, the oil preventing effect is better; the oil seal sheets on the inner oil-proof assembly are designed into a sawtooth shape, and compared with a plane, oil scraping is more thorough and the oil scraping effect is better; through the cooperation with an oil return tank on the feet dog rack guide rail, oil can be recovered; by arranging the two oil seal sheets in the oil baffle, gaps are formed between the oil seal sheets and the oil baffle, oil scraped from the first oil seal sheet can enter the gaps, oil scraping interference between the first oil seal sheet and the second oil seal sheet is avoided, and meanwhile the oil return function can be effectively achieved. The invention belongs to the technical field of oil leakage prevention of the sewing machine.
