Description

Technical Field

[0001] This utility model relates to the field of sewing machine teeth technology, specifically to an intelligent sewing machine teeth assembly. Background Technology

[0002] The sewing machine feed dog is mainly used to move the fabric by driving the feed dog when the sewing needle is sewing, so that the sewing machine can continuously sew the fabric.

[0003] According to a sewing machine toother assembly disclosed in the public notice (Announcement No.: CN219568241U), the above application involves installing multiple U-shaped plates on the inner walls of the first and second guide rails. The rollers inside the U-shaped plates contact the grooves on the outer wall of the slide rod, converting sliding friction into rolling friction. This greatly reduces the friction between the first and second guide rails and the slide rod, preventing wear and damage to the surfaces of the first and second guide rails and the slide rod. The multiple rollers on the side wall of the U-shaped plates make rolling contact with the inner wall of the grooves, reducing friction between the U-shaped plates and the grooves and preventing leakage of lubricating oil.

[0004] However, after long-term use of the sewing machine, the feed dog is prone to misalignment when it moves repeatedly. When the feed dog of the existing sewing machine is misaligned, the sewing machine can only be opened for repair. It is not possible to adjust the misaligned feed dog while it is moving, which affects the working efficiency of the sewing machine. In view of this, we propose an intelligent sewing machine feed dog assembly. Utility Model Content

A baffle is slidably connected to the inner wall of the clamping block, and a through slot is provided on the outer wall of the baffle. When the feed dog is misaligned and will collide with the feed opening of the sewing machine during movement, the feed dog and the feed opening push the pressure plate, causing the pressure plate to drive the push plate to move. This allows the jamming block to extend and retract, thereby changing the position of the fixed base.

[0010] Preferably, the size of the slot matches the size of the insert block, the insert block passes through the clamping block and engages with the slot, so that after the baffle slides on the clamping block, the insert block can be engaged with the slot by pressing a button, thereby fixing the baffle and allowing the anti-jamming component to adjust the feed teeth of different heights.

[0011] Preferably, the gap between the locking block and the teeth of the gear plate is the same size, the end of the fixing spring away from the locking block is fixedly connected to the inner wall of the fixing seat, and there are two sets of locking blocks and gears. The two sets of locking blocks and gears are mirror-distributed on the inner walls of both ends of the fixing seat, so that when the limiting block locks the locking block, the locking block can fix the gear plate to the fixing seat.

[0012] Preferably, the end of the card block near the connecting seat has a notch, the two sides of the notch match the two sides of the limiting block, the limiting block fits into the card slot, so that when the feed tooth is squeezed, the push plate is driven by the pressure plate, and when the limiting block leaves the card block, the fixed seat can move.

[0013] Preferably, the end of the pressure plate away from the clamping block is provided with a movable groove, and the end of the push plate near the pressure plate is provided with a movable block. The thickness of the movable block is the same as that of the movable groove, and the cross-sectional area of ​​the movable groove is larger than that of the movable block, so that the pressure plate can drive the push plate to move, thereby enabling the fixed seat to adjust the misaligned feed teeth. A sleeve is provided at the connection between the pressure plate and the push plate on the outer wall of the fixed seat to prevent the push plate and the pressure plate from colliding.

[0014] Preferably, the outer wall of the fixed seat is provided with a through groove, the toothed plate is slidably connected to the inner wall of the groove, the gear is rotatably connected to the inner wall of the groove, and the gear meshes with the toothed plate, so that the fixed seat can move stably on the toothed plate.

[0015] Compared with the prior art, the present invention provides an intelligent sewing machine teeth assembly, which has the following beneficial effects:

[0016] 1. In this intelligent sewing machine feed dog assembly, when the feed dog is misaligned, the feed dog and the feed opening push the pressure plate, causing the pressure plate to move the push plate, thereby causing the limit block to disengage from the locking block. The locking block extends and retracts, and the fixed seat continues to move under the drive of the feed roller until the fixed seat moves to the point where the feed dog leaves the feed opening. At this time, the return spring pushes the push plate to reset, causing the limit block to lock the locking block again, fixing the position of the fixed seat, and ensuring that the feed dog will not collide with the feed opening during the next feed, thus improving the working efficiency of the sewing machine.

[0017] 2. This intelligent sewing machine feed dog assembly uses a sliding baffle to align the upper end of the baffle with the feed dog teeth. At this point, a button can be pressed to engage the insert with the slot, thus fixing the baffle. This allows the anti-jamming component to be adjusted for feed dogs of different heights, improving the feed dog assembly's usability. Attached Figure Description

[0024] like Figures 1-5As shown, this utility model provides a technical solution: an intelligent sewing machine toother assembly, including a sleeve 1, a bolt 2 threadedly connected to the outer wall of the sleeve 1, an installation cylinder 3 rotatably connected to the outer wall of the sleeve 1, an arc plate 4 fixedly connected to the outer wall of the installation cylinder 3, a toothed plate 5 fixedly connected to the outer wall of the arc plate 4, a fixing seat 6 provided on the outer wall of the toothed plate 5, a threaded hole 7 opened on the outer wall of the fixing seat 6, a connecting seat 8 fixedly connected to the end of the toothed plate 5 away from the arc plate 4, and an adjustment component 9 provided inside the fixing seat 6, the adjustment component 9 including a locking block 91, a fixing spring 92, a pressure plate 93, a push plate 94, a limiting block 95, a reset spring 96, and a gear 97.

[0025] In one embodiment of this utility model, the locking block 91 is slidably connected to the inner wall of the fixed base 6, and a fixing spring 92 is fixedly connected to the end of the locking block 91 away from the toothed plate 5. A pressure plate 93 is rotatably connected to the outer wall of the fixed base 6.

[0026] In one embodiment of the present invention, a push plate 94 is slidably connected to the inner wall of the fixed base 6, a limit block 95 is fixedly connected to the outer wall of the push plate 94, a return spring 96 is fixedly connected to the end of the push plate 94 away from the connecting base 8, and a gear 97 is rotatably connected to the inner wall of the fixed base 6.

[0027] In addition, an anti-jamming component 10 is provided on the outside of the fixed base 6. The anti-jamming component 10 includes a clamping block 101, which is fixedly connected to the end of the pressure plate 93 away from the fixed base 6. A button 102 is fixedly connected to the outer wall of the clamping block 101. The output end of the button 102 passes through the outer wall of the clamping block 101 and is fixedly connected to an insert block 103. A baffle 104 is slidably connected to the inner wall of the clamping block 101. A through slot 105 is provided on the outer wall of the baffle 104. When the feed tooth is misaligned and will hit the feed opening of the sewing machine during movement, the feed tooth and the feed opening push the pressure plate 93, causing the pressure plate 93 to drive the push plate 94 to move. This allows the clamping block 91 to extend and retract, thereby changing the position of the fixed base 6. This prevents the feed tooth from hitting the feed opening during the next feed, improving the working efficiency of the sewing machine.

[0028] In this embodiment of the utility model, the size of the slot 105 matches the size of the insert 103. The insert 103 passes through the clamping block 101 and engages with the slot 105. After the baffle 104 slides on the clamping block 101, the insert 103 can be engaged with the slot 105 by pressing the button 102, thereby fixing the baffle 104. This allows the anti-jamming component 10 to adjust the feed teeth at different heights, improving the usability of the tooth frame.

[0029] In this embodiment of the utility model, the gap between the locking block 91 and the teeth of the toothed plate 5 is the same size. The end of the fixing spring 92 away from the locking block 91 is fixedly connected to the inner wall of the fixing seat 6. There are two sets of locking blocks 91 and gears 97. The two sets of locking blocks 91 and gears 97 are mirror-distributed on the inner walls of both ends of the fixing seat 6. When the limiting block 95 locks the locking block 91, the locking block 91 can fix the toothed plate 5 and the fixing seat 6, preventing the feeding teeth from loosening during fabric feeding and making it difficult to feed the fabric out.

[0030] In an embodiment of this utility model, a notch is provided at one end of the card block 91 near the connecting seat 8. The two sides of the notch match the two sides of the limiting block 95. The limiting block 95 fits into the card slot, so that when the feeding tooth is squeezed, the push plate 94 is driven by the pressure plate 93, and the limiting block 95 leaves the card block 91, so that the fixed seat 6 can move, thereby ensuring the stability of the fixed seat 6 when no adjustment is required.

[0031] In an embodiment of this utility model, a movable groove is provided at the end of the pressure plate 93 away from the clamping block 101, and a movable block is provided at the end of the push plate 94 near the pressure plate 93. The thickness of the movable block is the same as that of the movable groove, and the cross-sectional area of ​​the movable groove is larger than that of the movable block, so that the pressure plate 93 can drive the push plate 94 to move, thereby enabling the fixed seat 6 to adjust the misaligned feed teeth. A sleeve is provided at the connection between the pressure plate 93 and the push plate 94 on the outer wall of the fixed seat 6 to prevent the push plate 94 from colliding with the pressure plate 93.

[0032] In an embodiment of this utility model, a through groove is provided on the outer wall of the fixed base 6, the toothed plate 5 is slidably connected to the inner wall of the groove, the gear 97 is rotatably connected to the inner wall of the groove, and the gear 97 meshes with the toothed plate 5, so that the fixed base 6 can move stably on the toothed plate 5, thereby improving the accuracy of adjustment.

[0033] In this invention, during use, the clip 1 is fixed to the sewing machine with bolts 2, both ends of the mounting cylinder 3 are connected to the feed roller, the connecting seat 8 is connected to the sewing needle, and the feed dog is fixed to the fixing seat 6. At this time, the sliding baffle 104 is made so that the upper end of the baffle 104 is parallel to the feed dog. Then, the button 102 can be pressed to make the insert 103 engage with the slot 105, thereby fixing the baffle 104. This allows the anti-jamming component 10 to adjust the feed dog at different heights, improving the usability of the feed dog. During long-term use of the sewing machine, the feed dog is prone to misalignment, which may cause the feed dog to... The feed tooth will impact the feed opening, causing it to jam. At this time, the feed tooth and the feed opening push the pressure plate 93, which in turn moves the push plate 94, causing the limit block 95 to disengage from the locking block 91. The locking block 91 can then extend and retract. The fixed seat 6 continues to move under the action of the feed roller, and the locking block 91 continues to extend and retract until the fixed seat 6 is displaced until the feed tooth leaves the feed opening. At this time, the return spring 96 pushes the push plate 94 to reset, causing the limit block 95 to re-lock the locking block 91, fixing the position of the fixed seat 6, and preventing the feed tooth from impacting the feed opening during the next feed, thus improving the working efficiency of the sewing machine.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
