The replaceable slot-shaped sewing presser foot device can be used to sew arc-shaped stitches with flat sewing, and only two components need to be replaced to achieve sewing of different regular arc-shaped lines, thereby saving the cost of a pattern machine head, improving product quality consistency, improving processing efficiency, greatly reducing the involvement of manual labor, and saving time and effort.

[0004] An embodiment of the present application provides a replaceable slot-shaped sewing presser foot device.

[0005] A replaceable slot-shaped sewing presser foot device includes a mounting base, a limiting column, a limiting slot plate, a moving mechanism, and a sewing presser foot. The limiting column is movably connected to the mounting base. The limiting slot plate is movably connected to the mounting base. The moving mechanism is mounted on the mounting base and connected to the limiting slot plate to drive the limiting slot plate to move. The limiting slot plate can be detached from the mounting base. The limiting slot plate is provided with a limiting passage. The limiting column can extend into the limiting passage through telescopic movement. The sewing presser foot is connected to the limiting slot plate. The sewing presser foot is provided with a sewing passage. The shape of the sewing passage is the same as that of the limiting passage.

[0006] In some embodiments, the replaceable slot-shaped sewing presser foot device further includes a limiting driving component connected to the limiting column. The limiting driving component is used to drive the limiting column to move.

[0007] In some embodiments, the limiting driving component can drive the limiting column to move up and down in the vertical direction.

[0008] In some embodiments, the moving mechanism comprises a moving base and a moving driving component, the limiting groove plate is movably connected to the moving base and can move along a first direction in a horizontal direction, and the moving driving component is used to drive the moving base to move along a second direction in the horizontal direction, the first direction being perpendicular to the second direction.

[0009] In some embodiments, the moving mechanism further comprises a moving guide rail extending along the second direction, and the moving base is slidingly connected to the moving guide rail.

[0010] In some embodiments, the limiting groove plate is detachably connected to the moving mechanism, and the sewing presser plate is detachably connected to the limiting groove plate.

[0011] In some embodiments, the limiting channel is arc-shaped, and correspondingly, the sewing channel is arc-shaped.

[0012] In some embodiments, the replaceable-groove-shaped sewing presser plate device further comprises a rotating component, the sewing presser plate is connected to the limiting groove plate through the rotating component, and the rotating component can drive the sewing presser plate to lift or press down.

[0013] In some embodiments, the rotating component comprises a rotating base and a rotating driving component, the sewing presser plate is movably connected to the limiting groove plate through the rotating base, and the rotating driving component is connected to the sewing presser plate to drive the sewing presser plate to rotate along a vertical direction.

[0014] In some embodiments, the rotating component further comprises a rotating sliding member, the rotating sliding member is connected to the rotating base, the vertical position of the rotating sliding member on the rotating base is adjustable, the sewing presser plate is movably connected to the rotating sliding member, and the rotating driving component is mounted on the rotating sliding member and connected to the sewing presser plate.

[0015] An embodiment of the present application further provides a sewing device.

[0016] A sewing device comprises a sewing machine table, a sewing machine head, and the replaceable-groove-shaped sewing presser plate device, the sewing machine head is mounted on the sewing machine table, the replaceable-groove-shaped sewing presser plate device is mounted on the sewing machine table, the sewing presser plate of the replaceable-groove-shaped sewing presser plate device is located below a sewing needle of the sewing machine head, and the sewing needle can perform sewing through the sewing channel of the sewing presser plate of the replaceable-groove-shaped sewing presser plate device.

[0017] The replaceable slot-shaped sewing presser device can be used to sew arc-shaped lines by using a flat sewing machine. When different regular arc-shaped lines need to be sewn, only two parts need to be replaced, thereby saving the cost of the pattern machine head, improving the consistency of the quality of the sewing products, improving the processing efficiency, greatly reducing the labor participation, saving time and effort. Specifically, when the sewing presser plate presses the cloth piece into the specified position, the limiting column moves into the limiting channel of the limiting slot plate, and the moving mechanism drives the limiting slot plate to move along the X-axis in the horizontal direction. Due to the fixed limiting effect of the limiting column, the limiting slot plate moves along the X-axis direction under the driving of the moving mechanism, and at the same time, moves along the Y-axis in the horizontal direction under the cooperation of the limiting column and the limiting channel. Because the shape of the sewing channel on the sewing presser plate is the same as that of the limiting channel, the sewing presser plate can also move synchronously along the X-axis and Y-axis in the horizontal direction, thereby realizing straight-line or non-straight-line sewing. In addition, the sewing needle reciprocates in the Z-axis direction to realize sewing of the cloth piece. It should be noted that the sewing channel can be a straight-line channel. When the sewing channel and the limiting channel are both straight-line channels, the limiting slot plate does not move in the Y-axis direction when the moving mechanism drives it to move along the X-axis. The sewing channel can be a non-straight-line such as an arc. When the sewing channel and the limiting channel are both arc-shaped channels, the limiting slot plate moves synchronously along the X-axis and Y-axis when the moving mechanism drives it, thereby realizing arc-shaped sewing, thereby forming a track that can be used to sew different arc-shaped lines by using a flat sewing machine. When different arc-shaped lines need to be sewn, only the limiting slot plate and the sewing presser plate need to be replaced, without replacing the head of the pattern machine. Therefore, for different arc-shaped sewing, only a few limiting slot plates and sewing presser plates with different arc-shaped shapes are needed, thereby greatly reducing the equipment cost and production cost, and saving labor cost.

[0030] The embodiment of the present application provides a replaceable slot-shaped sewing presser foot device 10 to solve the problems of manual operation, difficult to ensure product quality consistency and low processing efficiency in the prior art when manually moving the fabric piece according to the sewing line path to sew the arc-shaped line.

[0031] The replaceable slot-shaped sewing presser foot device 10 provided by the embodiment of the present application is exemplarily shown in Figure 1 The structure schematic diagram of the replaceable slot-shaped sewing presser foot device 10 provided by the embodiment of the present application is shown in Figure 1 The replaceable slot-shaped sewing presser foot device 10 provided by the embodiment of the present application can be used for arc-shaped sewing line sewing.

[0032] In order to more clearly illustrate the structure of the replaceable slot-shaped sewing presser foot device 10, the replaceable slot-shaped sewing presser foot device 10 will be introduced in combination with the drawings.

[0033] The replaceable slot-shaped sewing presser foot device 10 provided by the embodiment of the present application is exemplarily shown in Figure 1 The structure schematic diagram of the replaceable slot-shaped sewing presser foot device 10 provided by the embodiment of the present application is shown in Figure 1A structure schematic diagram of a replaceable slot-shaped sewing presser foot device 10 is provided in the embodiments of the present application. The replaceable slot-shaped sewing presser foot device 10 comprises a mounting base 100, a limiting column 200, a limiting slot plate 300, a moving mechanism 400 and a sewing presser foot 500.

[0034] The limiting column 200 is movably connected to the mounting base 100. The limiting slot plate 300 is movably connected to the mounting base 100. The moving mechanism 400 is installed on the mounting base 100 and connected to the limiting slot plate 300 for driving the limiting slot plate 300 to move. The limiting slot plate 300 is provided with a limiting passage 310. The limiting slot plate 300 can be detached from the mounting base 100. The limiting passage 310 on the limiting slot plate 300 has multiple specifications, and the corresponding limiting slot plate 300 can be selected according to the actual needs of the sewing track. The limiting column 200 can move in an extending manner into the limiting passage 310. The sewing presser foot 500 is connected to the limiting slot plate 300. The sewing presser foot 500 is provided with a sewing passage 510. The shape of the sewing passage 510 is the same as that of the limiting passage 310.

[0035] In use, the limiting column 200 can move in the vertical direction and is fixed in position in the horizontal direction. After the limiting column 200 is extended into the limiting passage 310, the moving mechanism 400 drives the limiting slot plate 300 to move along the X-axis direction in the horizontal direction. Due to the limiting action of the limiting column 200, the limiting slot plate 300 can also passively move in the Y-axis direction due to the restriction of the arc-shaped limiting passage 310. Thus, the sewing presser foot 500 with the same shape of the sewing passage 510 is driven to move along the X-axis and Y-axis directions at the same time, and then the movement of the sewing needle in the Z-axis direction is matched to complete the sewing of the arc-shaped sewing track of the fabric piece. When different shapes of arc-shaped sewing tracks need to be sewn, only the limiting slot plate 300 and the sewing presser foot 500 with different shapes need to be replaced, and the sewing machine head does not need to be replaced, thereby saving the production equipment cost.

[0036] In some embodiments, the replaceable slot-shaped sewing presser foot device 10 further comprises a limiting driving component 600. The limiting driving component 600 is connected to the limiting column 200. The limiting driving component 600 is used for driving the limiting column 200 to move. Preferably, the limiting driving component 600 can be a driving motor.

[0037] In some embodiments, the limiting driving component 600 can drive the limiting column 200 to move up and down in the vertical direction. Preferably, as shown in Figure 2 Figure 2 ​This is a side view of the replaceable slotted sewing press plate device 10 according to an embodiment of the present invention. The limiting drive component 600 can be a linear cylinder. The limiting drive component 600 is installed in the vertical direction, and the limiting post 200 is installed in the vertical direction on the limiting drive component 600.

[0038] In some of these embodiments, see Figure 1 and Figure 2 As shown, the moving mechanism 400 includes a moving base 410 and a moving drive component 420. A limiting slot plate 300 is movably connected to the moving base 410. The limiting slot plate 300 is capable of moving horizontally along a first direction relative to the moving base 410. The moving drive component 420 drives the moving base 410 to move horizontally along a second direction. The first direction is perpendicular to the second direction. For example, the first direction is the Y-axis direction, and the second direction is the X-axis direction.

[0039] In some of these embodiments, see Figure 1 and Figure 2 As shown, the moving mechanism 400 also includes a moving guide rail 430. The moving guide rail 430 is a linear guide rail that extends along the second direction, and the moving seat 410 is slidably connected to the moving guide rail 430. The moving guide rail 430 is provided to restrict the movement of the sliding seat and the limiting groove plate 300 along the second direction.

[0040] In some embodiments, the limiting groove plate 300 is detachably connected to the moving mechanism 400. The sewing pressure plate 500 is detachably connected to the limiting groove plate 300. The detachable connection between the limiting groove plate 300 and the moving mechanism 400, and the detachable connection between the sewing pressure plate 500 and the limiting groove plate 300, facilitates the removal and replacement of the limiting groove plate 300 and the sewing pressure plate 500.

[0041] In some embodiments, the limiting channel 310 is arc-shaped, and correspondingly, the sewing channel 510 is arc-shaped. It is easy to understand that the specific shape of the arc can be set according to the stitches to be sewn on the fabric piece. It is also easy to understand that the aforementioned limiting channel 310 and sewing channel 510 can be straight.

[0042] In some of these embodiments, see Figure 1 and Figure 2 As shown, the replaceable slotted sewing presser plate device 10 also includes a rotating component 700. The sewing presser plate 500 is connected to the limiting slot plate 300 via the rotating component 700. The rotating component 700 can drive the sewing presser plate 500 to lift or press down. The rotating component 700 enables the sewing presser plate 500 to rotate, so as to weave the fabric piece to be sewn under the sewing presser plate 500.

[0043] In some of these embodiments, see Figure 1 andFigure 2 As shown, the rotating component 700 includes a rotating base 710 and a rotating drive component 720. The sewing presser plate 500 is movably connected to the limiting groove plate 300 via the rotating base 710. The rotating drive component 720 is connected to the sewing presser plate 500 to drive the sewing presser plate 500 to rotate in the vertical direction.

[0044] In some embodiments, the rotary drive component 720 may be a drive motor.

[0045] In some of these embodiments, see Figure 2 As shown, the rotary component 700 also includes a rotary slider 730. The rotary slider 730 is connected to the rotary base 710. The vertical position of the rotary slider 730 on the rotary base 710 is adjustable. The sewing presser plate 500 is movably connected to the rotary slider 730, and the rotary drive component 720 is mounted on the rotary slider 730 and connected to the sewing presser plate 500. The rotary slider 730 can be adjusted vertically relative to the rotary base 710 to adapt to different pattern making machines.

[0046] In some embodiments, the materials of the limiting groove plate 300 and the sewing pressure plate 500 can be independently selected from materials such as metals and alloys.

[0047] An embodiment of this application also provides a sewing device.

[0048] A sewing machine includes a sewing machine table, a sewing machine head, and the aforementioned replaceable slotted sewing presser plate device 10. The sewing machine head is mounted on the sewing machine table, and the replaceable slotted sewing presser plate device 10 is mounted on the sewing machine table. The sewing presser plate 500 of the replaceable slotted sewing presser plate device 10 is located under the sewing needle of the sewing machine head, allowing the sewing needle to pass through the sewing channel 510 of the replaceable slotted sewing presser plate 500 for sewing. The sewing machine has an attached... Figure 1 Appendix Figure 2 Not shown in the diagram. The sewing machine head can be a pattern sewing machine. The above-described sewing equipment can be used for sewing irregular fabric pieces, such as fabric pieces that require the sewing of curved stitches. For processing and sewing fabric pieces of different specifications, the appropriate limiting groove plate 300 and sewing pressure plate 500 can be selected according to the corresponding sewing stitch.

[0049] The replaceable slot-shaped sewing presser device 10 is used as follows: when the sewing presser 500 presses the cloth piece to the designated position, the limiting column 200 is actuated to extend into the limiting passage 310 of the limiting slot plate 300, and the moving mechanism 400 is actuated to drive the limiting slot plate 300 to move along the X axis in the horizontal direction. Due to the fixed limiting effect of the limiting column 200, the limiting slot plate 300 moves along the X axis under the driving of the moving mechanism 400, and at the same time, moves along the Y axis in the horizontal direction under the cooperation of the limiting column 200 and the limiting passage 310. Since the shape of the sewing passage 510 on the sewing presser 500 is the same as that of the limiting passage 310, the sewing presser 500 can also move along the X axis and the Y axis in the horizontal direction synchronously, so that straight or non-straight sewing lines can be achieved. In addition, the sewing needle reciprocates along the Z axis to achieve sewing of the cloth piece. It should be noted that the sewing passage 510 can be a straight passage. When the sewing passage 510 and the limiting passage 310 are both straight passages, the limiting slot plate 300 does not move along the Y axis when the moving mechanism 400 drives it to move along the X axis. The sewing passage 510 can be non-straight, such as arc-shaped. When the sewing passage 510 and the limiting passage 310 are both arc-shaped passages, the limiting slot plate 300 moves along the X axis and the Y axis synchronously under the driving of the moving mechanism 400, so that arc-shaped sewing lines can be achieved, thereby forming a track that can be used to sew different arc-shaped lines with a flat sewing machine. When different arc-shaped lines need to be sewn, only the limiting slot plate 300 and the sewing presser 500 need to be replaced, without the need to replace the head of the pattern machine. Therefore, for different arc-shaped sewing, only a few limiting slot plates 300 and sewing pressers 500 with different arc-shaped shapes need to be provided, which greatly reduces the cost of equipment and production, speeds up the replacement, and saves labor costs.

[0050] In summary, the replaceable slot-shaped sewing presser device 10 can be used to sew arc-shaped lines with a flat sewing machine. When different regular arc-shaped lines need to be sewn, only two components need to be replaced, which saves the cost of the head of the pattern machine, ensures high consistency of the quality of the sewn products, and improves the processing efficiency and greatly reduces the involvement of manual labor, thereby saving time and effort.

[0051] In the above embodiments, the description of each embodiment focuses on different aspects. The parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0052] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0053] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
