A four-needle six-thread sewing machine teeth frame

Abstract

This utility model discloses a feed dog for a four-needle six-thread sewing machine, including a differential feed dog and a main feed dog. The sliding groove one and the sliding groove two of the differential feed dog are both integrally formed, and the sliding groove one and the sliding groove two are movably connected by a slider. This utility model employs an integrally forged, closed slider groove structure, combined with vertical grinding for precision machining. This ensures that the grinding pattern of the feed dog slider groove is in the same direction as the feed dog's movement trajectory, effectively reducing frictional wear between the groove and the slider. This significantly improves the wear resistance of the feed dog, extends its overall service life, and reduces user operating and maintenance costs.

Description

Technical Field

[0001] This utility model relates to the technical field of sewing machine parts, specifically to a four-needle six-thread sewing machine teeth. Background Technology

[0002] The slider groove of the current four-needle six-thread sewing machine's common toother assembly is open-type, such as... Figure 2 As shown, an additional sealing plate is required and screws are used to lock the slot, thereby restricting the movement trajectory of the slider. This structure has obvious shortcomings: on the one hand, the grinding pattern of the open-type toothed slider slot is inconsistent with the actual movement trajectory of the toothed slot during processing, which causes abnormal wear of the toothed slot during long-term use of the sewing machine. This not only shortens the product's service life but also increases the customer's maintenance and replacement costs.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes a four-needle six-thread sewing machine teeth, which can overcome the above-mentioned deficiencies of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A four-needle six-thread sewing machine feeder includes a differential feeder and a main feeder. The sliding groove one of the differential feeder and the sliding groove two of the main feeder are both integrally formed, and the sliding groove one and the sliding groove two are movably connected by a slider.

[0006] Furthermore, the upper and lower ends of the slider are provided with two sets of slider protrusions arranged side by side.

[0007] Furthermore, the upper and lower ends of the sliding groove are provided with slider tracks that match the corresponding slider protrusions.

[0008] Furthermore, the upper and lower ends of the sliding groove are provided with slider tracks that match the corresponding slider protrusions.

[0009] Furthermore, the slider protrusion structures may be the same or different.

[0010] Furthermore, the slider has a hole in the middle.

[0011] The beneficial effects of this utility model are as follows: This utility model adopts an integrated closed slider groove structure formed by integral forging and is precision machined by vertical grinding process, so that the grinding pattern of the slider groove of the dental cartilage is in the same direction as the movement trajectory of the dental cartilage, effectively reducing the friction loss between the groove and the slider, thereby significantly improving the wear resistance of the dental cartilage, extending the overall service life, and reducing the user's use and maintenance costs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figure 1 As shown, a four-needle six-thread sewing machine feeder according to an embodiment of the present invention includes a differential feeder 1 and a main feeder 2. The sliding groove 3 of the differential feeder 1 and the sliding groove 4 of the main feeder 2 are both integrally formed. The sliding groove 3 and the sliding groove 4 are movably connected by a slider 5.

[0016] The upper and lower ends of the slider 5 are each provided with two sets of slider protrusions arranged side by side. The upper and lower ends of the sliding groove 3 are provided with slider tracks 1 that match the corresponding slider protrusions. The upper and lower ends of the sliding groove 4 are provided with slider tracks 2 that match the corresponding slider protrusions.

[0017] The protruding structures of the sliders may be the same or different. A hole 6 is provided in the middle of the slider 5.

[0018] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0019] In practical use, according to the four-needle six-thread sewing machine feeder described in this utility model, the feeder is forged into a single, enclosed slider groove. The main feeder, driven by the right connecting rod, reciprocates back and forth around the slider as a fulcrum. The differential feeder, driven by the left connecting rod, also reciprocates back and forth around the slider as a fulcrum. The feeder assembly swings up and down around the slider as a fulcrum, driven by the lifting rod. During post-processing, a vertical grinding process is used to ensure that the slider groove pattern of the feeder is in the same direction as the feeder's movement trajectory, improving product quality and increasing product lifespan.

[0020] In summary, by employing the integrated closed slider groove structure formed by integral forging and precision machining using vertical grinding, the grinding pattern of the slider groove of the dental cartilage is aligned with the movement trajectory of the dental cartilage, effectively reducing frictional loss between the groove and the slider. This results in significantly improved wear resistance of the dental cartilage, extended overall service life, and reduced user usage and maintenance costs.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
