Description

Technical Field

[0001] This invention relates to a rope embroidery, and more particularly to a simple rope embroidery structure. Background Technology

[0002] Due to the limited space at the head of the embroidery machine, existing rope embroidery typically includes two structures.

[0003] 1. An independent cord feeder structure is set on one side of the needle bar frame to cooperate with a needle bar on the needle bar frame. The cord feeder structure is relatively complicated and can only cooperate with one needle bar, which is not convenient for color changing.

[0004] 2. A rope feeding structure with a rope feeding hole is installed on the presser foot corresponding to each needle bar, serving as a multi-functional, simple rope embroidery tool. This rope feeding structure can function as both a presser foot and simultaneously feed rope. A motor is then installed to drive the presser foot with the rope feeding structure, effectively enabling color changes. However, the independent presser foot drive mechanism is costly and ineffective in rope embroidery. Furthermore, in flat embroidery, the independent presser foot drive motor and the machine system drive motor may experience some misalignment due to power or program settings issues. Therefore, this simple rope embroidery solution is rather impractical and has limited real-world value.

[0005] In addition, due to the limited space in the embroidery machine head, the presser foot rod of the presser foot with the rope feeding hole structure is relatively thin, which is easily damaged during embroidery. Summary of the Invention

[0006] To address the problems existing in the use of the prior art, this invention provides a simple rope embroidery structure that is easy to construct and has high practical value.

[0007] The technical solution of this invention to solve the existing problems is: a simple rope embroidery structure, including a needle bar frame, wherein the needle bar frame has at least two needle bar mounting positions, wherein at least one needle bar mounting position is equipped with a first needle bar. As an improvement, the needle bar on the side adjacent to the first needle bar is provided with a presser foot rod that cooperates with the first needle bar. The bottom of the presser foot rod is provided with a first presser foot that cooperates with the needle on the first needle bar for sewing. The first presser foot is provided with a needle hole or needle groove that cooperates with the needle on the first needle bar and allows the needle to pass through for sewing. The first presser foot is also provided with a rope guide hole or rope guide groove that can guide the rope into the needle hole or needle groove. The presser foot rod is provided with a lifting block and a driving block, and the first needle bar is provided with a lifting block that can cooperate with the lifting block and the driving block.

[0008] As a further improvement, the presser foot rod is provided with a first presser foot spring that drives the first presser foot.

[0009] As a further improvement, the lifting block is provided with a sliding hole or sliding groove to accommodate the pressure foot rod.

[0010] As a further improvement, the lifting block can be installed in an adjustable position on the corresponding first needle bar.

[0011] As a further improvement, the inlet of the guide rope hole or guide rope groove is located at the front of the needle bar frame.

[0012] As a further improvement, the presser foot is provided with a manual or / and motorized lifting mechanism.

[0013] As a further improvement, a positioning structure is provided between the needle bar holder and the presser foot rod to position the idle presser foot rod in an idle position.

[0014] As a further improvement, the positioning structure includes a baffle plate connecting the needle bar frame and a positioning bolt for the presser foot rod in the idle position. The positioning plate on the presser foot rod is provided with a positioning hole or positioning groove that mates with the positioning bolt.

[0015] As a further improvement, a rope guide structure that mates with the rope guide hole or rope guide groove is also included.

[0016] As a further improvement, the needle bar holder is also provided with at least one second needle bar for flat embroidery, the second needle bar being provided with a matching flat embroidery presser foot.

[0017] Compared with existing technologies, this invention features a first needle bar mounted at least once on a needle bar holder. A presser foot is positioned on the adjacent side of the first needle bar, with a first presser foot at its bottom. The first presser foot has a needle hole or groove and a guide hole or groove. The presser foot has a lifting block and a driving block, and the first needle bar has a lifting block that cooperates with the lifting block and driving block for sewing. Its advantages are that when the first needle bar descends, the lifting block cooperates with the driving block on the presser foot to push the first presser foot downwards; when the first needle bar rises, the lifting block cooperates with the lifting block on the presser foot to drive the first presser foot upwards, thus realizing the entire working process of the needle bar and the first presser foot during flat embroidery or rope embroidery. This invention has a simple and compact structure. It does not require a separate motor; it can achieve both rope and flat embroidery through needle bar drive. It is low-cost and effectively meets the multi-functional needs of both flat and rope embroidery. Attached Figure Description

Detailed Implementation

[0026] See Figure 1-8 This embodiment presents a simple rope embroidery structure, including a needle bar frame 1. The needle bar frame 1 has at least two needle bar mounting positions, at least one of which is equipped with a first needle bar 2. A presser foot 3, cooperating with the first needle bar 2, is located on the adjacent needle bar position. The bottom of the presser foot 3 has a first presser foot 4 that mates with the needle on the first needle bar 2 for sewing. The first presser foot 4 has a needle hole 41 or needle groove that mates with the needle on the first needle bar 2 for sewing. The first presser foot 4 also has a rope guide hole 42 or rope guide groove. The presser foot 3 has a lifting block 31 and a driving block 32. The first needle bar 2 has a lifting block 21 that mates with the lifting block 31 and the driving block 32. The rope guide hole 42 or rope guide groove connects to the needle hole 41 or needle groove, used to guide the rope 6 into the needle hole 41 or needle groove to achieve rope embroidery.

[0027] In this embodiment, the first presser foot 4 is provided with a pinhole 41 and a guide rope hole 42.

[0028] The first needle bar 2 is typically a standard needle bar. The number of first needle bars 2 installed can be adjusted according to actual needs. Referring to the attached diagram, this embodiment has four first needle bars 2 installed, facilitating color changes in simple cord embroidery. In the attached diagram, a presser foot 3 that mates with the corresponding first needle bar 2 is installed on the adjacent needle bar position to the right of each first needle bar 2.

[0029] The needle bar holder 1 can be equipped with all first needle bars 2 as needed, or it can be combined with needle bars of other functions as required. For example, a second needle bar 7 for flat embroidery can be installed. Referring to the attached diagram, the needle bar holder 1 also has at least one second needle bar 7 for flat embroidery, and the second needle bar 7 has a matching flat embroidery presser foot 71. The second needle bar 7 can be the same needle bar as the first needle bar 2, the main difference being that the second needle bar 7 has a matching flat embroidery presser foot 71. The specific driving, color changing, and operating principles of the first and second needle bars can refer to the needle bar driving and color changing structures and methods in existing flat embroidery techniques.

[0030] When the first needle bar 2 is needed, the needle bar frame 1 can be driven by the embroidery machine system, so that the corresponding first needle bar 2 on the needle bar frame 1 enters the working position and cooperates with the needle bar driver located in the working position, and can be driven by the needle bar driver to work. The needle bar driver drives the corresponding first needle bar 2 that has entered the working position to move up and down reciprocally. When the first needle bar 2 moves downward, the lifting block 21 on the first needle bar 2 moves downward with the first needle bar 2 until the lifting block 21 collides with the driving block 32 of the presser foot rod 3. The first needle bar 2 drives the driving block 32 downward through the lifting block 21, driving the presser foot rod 3 downward, thereby driving the first presser foot 4 downward, until the first needle bar 2 reaches the lower stop point and then returns to the upper position. The lifting block 21 on the returning first needle bar 2 collides with the lifting block 31 of the presser foot rod 3, lifting the lifting block 31 upward, driving the presser foot rod 3 upward, thereby driving the first presser foot 4 upward, and after rising to the upper stop point of the first needle bar 2, one stitch of embroidery is completed. The needle bar driver continues to drive the first needle bar 2 downward and then upward, repeating this process to complete the actions required for embroidery. This method is applicable to flat embroidery or cord embroidery.

[0031] When rope embroidery is needed, the rope is guided into the needle hole of the first presser foot 4 through the rope guide hole 42 or the rope guide groove, so that the needle on the first needle bar 2 can sew the rope onto the fabric when the first needle bar 2 moves up and down reciprocally. For ease of demonstration, Figure 2-4 In the middle, the different first needle bars 2 are in different positions.

[0032] As can be seen from the above actions, when the first needle bar 2 and the first presser foot 4 work together, the first presser foot 4 is driven entirely by the first needle bar 2. The first presser foot 4 does not require an independent drive motor and can complete rope embroidery. If necessary, it can also complete flat embroidery. Compared with the existing technology, it has a simple structure and low cost.

[0033] The presser foot lever 3 is equipped with a first presser foot spring 5 that drives the first presser foot 4. The first presser foot spring 5 drives the presser foot lever 3 so that the first presser foot 4 on the presser foot lever 3 can press onto the embroidered fabric, which facilitates the embroidery action when the first needle bar 2 moves down.

[0034] The lifting block 21 is provided with a sliding hole 22 or a sliding groove to accommodate the pressure foot rod 3. In this embodiment, the sliding hole 22 is preferred.

[0035] The lifting block 21 is installed on the corresponding first needle bar 2 in an adjustable position. The specific position of the lifting block 21 on the first needle bar 2 can be adjusted according to actual needs.

[0036] The rope feeding frame (not shown in the figure) is usually installed in front of or above the needle bar frame 1. In order to facilitate rope feeding, the inlet 43 of the rope 6 inlet hole 42 is set in front of the needle bar frame 1.

[0037] The presser foot lever 3 is equipped with a manual or / and motorized lifting mechanism. When the cord embroidery is not required, the presser foot lever 3 can be raised manually or by motorized lifting mechanism to prevent the first presser foot 4 from falling.

[0038] A positioning structure is provided between the needle bar holder 1 and the presser foot rod 3 to position the idle presser foot rod 3 in an idle position. The positioning structure is used to position the idle presser foot rod 3. When the first needle bar 2 is not in use, the presser foot rod 3 that cooperates with the first needle bar 2 will also be not in use. The positioning structure can be used to position the presser foot rod 3 to prevent it from falling and affecting other embroidery processes.

[0039] In this simplified embodiment, the positioning structure includes a baffle plate 12 connecting the needle bar frame 1 to the idle presser foot rod 3, and a positioning bolt 11. The positioning plate 44 on the presser foot rod 3 has a positioning hole 45 or a positioning groove that mates with the positioning bolt 11. The positioning bolt 11 can be installed on the baffle plate 12, engaging with the positioning hole 45 or positioning groove. Alternatively, the baffle plate 12 can have mounting holes for the positioning bolt 11. The positioning plate 44 is typically connected to the presser foot rod 3 and slides in conjunction with a guide groove on the needle bar frame 1 to prevent the presser foot rod 3 from rotating. Placing the positioning hole 45 or positioning groove on the positioning plate 44 greatly simplifies the positioning structure. Of course, the positioning structure can also be modified according to existing technology and actual conditions, specifically to ensure that the idle presser foot rod 3 is positioned and prevented from falling.

[0040] It also includes a rope guiding structure (not shown in the figure) that mates with the rope guide hole 42 or the rope guide groove. The rope guiding structure facilitates the guidance of the rope 6 from the rope conveyor frame into the guide hole 42. The rope guiding structure may include guide hooks or guide holes that are necessary in the rope conveying path. The rope guiding structure may be installed on a separate mounting bracket or on the rope conveyor frame.
