Description

Technical Field

[0001] This utility model generally relates to the field of computer embroidery machine technology, and more particularly to a rope embroidery device. Background Technology

[0002] Rope embroidery is a device that uses ropes of different colors as raw materials to embroider patterns onto fabric using an embroidery machine. Specifically, a thicker rope is supplied to the fabric, and then a finer silk thread is embroidered onto the fabric by the embroidery machine. The rope is then tied to the fabric by the silk thread, thus enriching the pattern on the fabric.

[0003] However, the two-color rope embroidery device in the relevant technology occupies a large space and can only be installed and used on embroidery machines with a large head-to-head distance. Utility Model Content

[0004] This utility model provides a rope embroidery device, including a first ring-beating wheel, a second ring-beating wheel, a first multi-stage transmission mechanism, and a second multi-stage transmission mechanism;

[0005] The first multi-stage transmission mechanism is used to drive the first ring wheel to rotate. The first multi-stage transmission mechanism includes at least two first transmission components connected in series. The first transmission components are belt transmission components or gear transmission components. The transmission ratio of each first transmission component is ;

[0006] The second multi-stage transmission mechanism is used to drive the second ring wheel to rotate. The second multi-stage transmission mechanism includes at least two second transmission components connected in series. The second transmission components are belt transmission components or gear transmission components, and the transmission ratio of each second transmission component is 1 to 3.

[0007] As an implementation method, the first multi-stage transmission mechanism includes a first gear transmission assembly and a first belt transmission assembly, wherein the transmission ratio of the first gear transmission assembly is 2 to 3, and the transmission ratio of the first belt transmission assembly is 2 to 3.

[0010] As an implementation method, each of the gear pairs has the same transmission ratio, which is greater than the transmission ratio of the second belt drive assembly.

[0011] As an implementation, the second belt drive assembly includes a second synchronous belt, and the first belt drive assembly includes a first synchronous belt, with the first and second synchronous belts located at the same height.

[0012] As an implementation method, the first ringing wheel and the second ringing wheel are arranged side by side in the left-right direction, and the line connecting the center of the first synchronous wheel and the center of the second synchronous wheel makes an angle β with the left-right direction, where 5°≤β≤25°;

[0013] The second belt drive assembly also includes a fifth synchronous pulley and a guide pulley. The first synchronous pulley, the fifth synchronous pulley and the third synchronous pulley are arranged from back to front. The guide pulley is located outside the second synchronous belt and is positioned close to the fifth synchronous pulley.

[0014] As an alternative implementation, a support assembly is also included. This support assembly comprises a first frame and a second frame connected to the first frame. A common plane of the first and second frames is located on the left or right side of the needle bar frame and on the front side of the needle bar frame. The common plane is inclined relative to the needle bar frame, forming an angle α with the front-rear direction, where 5° ≤ α ≤ 45°.

[0015] The first multi-stage transmission mechanism and the second multi-stage transmission mechanism are mounted on the first frame, and the second frame is used to mount the tensioning mechanism.

[0016] As an alternative implementation, the tensioning mechanism is further included, comprising a first tensioning component and a second tensioning component located at the same height. The first tensioning component and the second tensioning component are parallel to the common plane, and the orthographic projection of the first tensioning component on the projection plane is disposed away from the needle bar frame, while the orthographic projection of the second tensioning component on the projection plane is disposed close to the needle bar frame, wherein the projection plane is coplanar with the common plane.

[0017] As one possible implementation, the support assembly further includes a connecting plate and a vertical telescopic member. The movable end of the vertical telescopic member is capable of reciprocating in the vertical direction. The movable end of the vertical telescopic member is connected to the connecting plate, and the first frame is connected to the connecting plate.

[0018] The connecting plate has a first elongated hole in the front-back direction and a second elongated hole in the left-right direction. The first elongated hole in the front-back direction is used to adjust the spatial position of the first multi-stage transmission mechanism and the second multi-stage transmission mechanism in the front-back direction; the second elongated hole in the left-right direction is used to adjust the spatial position of the first multi-stage transmission mechanism and the second multi-stage transmission mechanism in the left-right direction.

[0019] In the above scheme, the first multi-stage transmission mechanism drives the first ring wheel through a graded series transmission method, with each stage having a transmission ratio of 1 to 3. The second multi-stage transmission mechanism drives the second ring wheel through a graded series transmission method, with each stage having a transmission ratio of 1 to 3. The small transmission ratio of each stage helps to make the transmission pair structure of each stage smaller, thereby reducing the overall size and space occupation of the entire multi-stage transmission mechanism and contributing to its miniaturization design. It can be installed and used not only on embroidery machines with large end-to-end distances but also on embroidery machines with small end-to-end distances. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] This application provides a rope embroidery device for use in a computerized embroidery machine. The rope embroidery device can be connected to the machine head, and works in conjunction with the machine head's needle to automatically embroider ropes or ribbons.

[0033] like Figures 1-3 As shown, the rope embroidery device includes a first loop-forming wheel 30, a second loop-forming wheel 40, a first multi-stage transmission mechanism 10, and a second multi-stage transmission mechanism 20. The first multi-stage transmission mechanism 10 drives the first loop-forming wheel 30 to rotate. The first multi-stage transmission mechanism 10 includes at least two first transmission components connected in series. Each first transmission component is a belt transmission component or a gear transmission component, and the transmission ratio of each first transmission component is 1 to 3. The second multi-stage transmission mechanism 20 drives the second loop-forming wheel 40 to rotate. The second multi-stage transmission mechanism 20 includes at least two second transmission components connected in series. Each second transmission component is a belt transmission component or a gear transmission component, and the transmission ratio of each second transmission component is 1 to 3.

[0034] In practical applications, such as Figure 1 As shown, the number of needles on the needle bar of a computerized embroidery machine can be 6, 8, 10, 12, etc. Taking 6 needles as an example: Needle No. 1 A is coaxially set with the first looping wheel 30, and needle No. 3 C is coaxially set with the second looping wheel. The color of the rope or ribbon corresponding to the first looping wheel 30 can be different from the color of the rope or ribbon corresponding to the second looping wheel 40.

[0035] The first multi-stage transmission mechanism 10 may include two first transmission components, three first transmission components, four first transmission components, etc., and the transmission ratio of each first transmission component is 1 to 3.

[0036] For example: Reference Figure 4As shown, the first multi-stage transmission mechanism 10 includes two first gear transmission assemblies 11, which are connected in series in stages to drive the first ring pulley 30 to rotate; or, the first multi-stage transmission mechanism 10 includes two first belt transmission assemblies 12, which are connected in series in stages to drive the first ring pulley 30 to rotate; or, the first multi-stage transmission mechanism 10 includes a first gear transmission assembly 11 and a first belt transmission assembly 12, which are connected in series in stages to drive the first ring pulley 30 to rotate.

[0037] The first multi-stage transmission mechanism 10 drives the first ring pulley 30 through a graded series transmission method. The transmission ratio of each stage is 1 to 3. The small transmission ratio of each stage helps to make the transmission pair structure of each stage smaller. For example, the diameter of the driving gear is 1 to 3 times the diameter of the driven gear; the diameter of the driving pulley is 1 to 3 times the diameter of the driven pulley. This can reduce the size of the entire first multi-stage transmission mechanism 10, avoid the first multi-stage transmission mechanism 10 occupying too much space, and help its miniaturization design.

[0038] refer to Figure 4 As shown, the second multi-stage transmission mechanism 20 may include two second transmission components, three second transmission components, four second transmission components, etc., and the transmission ratio of each second transmission component is 1 to 3.

[0039] For example: the second multi-stage transmission mechanism 20 includes three second gear transmission assemblies 21, which are connected in series in stages to drive the second ring pulley 40 to rotate; or, the second multi-stage transmission mechanism 20 includes three second belt transmission assemblies 22, which are connected in series in stages to drive the second ring pulley 40 to rotate; or, the second multi-stage transmission mechanism 20 includes two second gear transmission assemblies 21 and one second belt transmission assembly 22, which are connected in series in stages to drive the second ring pulley 40 to rotate; or, the second multi-stage transmission mechanism 20 includes one second gear transmission assembly 21 and two second belt transmission assemblies 22, which are connected in series in stages to drive the second ring pulley 40 to rotate.

[0040] The second multi-stage transmission mechanism 20 drives the second ring pulley 40 through a graded series transmission method. The transmission ratio of each stage is 1 to 3. The small transmission ratio of each stage helps to make the transmission pair structure of each stage smaller. For example, the diameter of the driving gear is 1 to 3 times the diameter of the driven gear; the diameter of the driving pulley is 1 to 3 times the diameter of the driven pulley. This can reduce the size of the entire second multi-stage transmission mechanism 20, avoid the second multi-stage transmission mechanism 20 occupying too much space, and help its miniaturization design.

[0041] In summary, the first multi-stage transmission mechanism 10 drives the first ring-forming wheel 30 through a graded series transmission method, with each stage having a transmission ratio of 1 to 3. The second multi-stage transmission mechanism 20 drives the second ring-forming wheel 40 through a graded series transmission method, with each stage having a transmission ratio of 1 to 3. The small transmission ratios at each stage contribute to smaller transmission pair structures at each stage, thereby reducing the overall size and space occupied by the entire multi-stage transmission mechanism and facilitating its miniaturization design. It can be installed and used not only on embroidery machines with large end-to-end spacing but also on embroidery machines with small end-to-end spacing.

[0042] Preferably, such as Figure 4 As shown, the first multi-stage transmission mechanism 10 includes a first gear transmission assembly 11 and a first belt transmission assembly 12. The transmission ratio of the first gear transmission assembly 11 is 2 to 3, and the transmission ratio of the first belt transmission assembly 12 is 2 to 3. The second multi-stage transmission mechanism 20 includes two second gear transmission assemblies 21 and one second belt transmission assembly 22. The transmission ratio of each gear pair is 1 to 2, and the transmission ratio of the second belt transmission assembly 22 is 1 to 2.

[0043] like Figure 4 As shown, the first gear transmission assembly 11 and the first belt transmission assembly 12 have the same transmission ratio, both being 2. The first gear transmission assembly 11 includes a meshing first gear 111 and a second gear 112, with the diameter of the first gear 111 being twice the diameter of the second gear 112. The first belt transmission assembly 12 includes a first synchronous pulley 121, a second synchronous pulley 122, and a first synchronous belt 123 wound around the first and second synchronous pulleys 121 and 122, with the diameter of the first synchronous pulley 121 being twice the diameter of the second synchronous pulley 122. The first synchronous pulley 121 and the second gear 112 are coaxially arranged. The second synchronous pulley 122 and the first ring pulley 30 are coaxially arranged. The output shaft of the first motor is vertically aligned, and the first motor drives the first gear 111 to rotate.

[0044] Gear transmission has the advantages of constant transmission ratio, high transmission efficiency and compact structure; synchronous belt transmission can transmit over a certain distance. By using a combination of gear transmission and synchronous belt transmission, the first multi-stage transmission mechanism 10 can arrange the components more flexibly.

[0045] like Figure 4As shown, all gear pairs have the same transmission ratio of 2. The second belt drive assembly 22 has a transmission ratio of 1, and the gear pair transmission ratio is greater than that of the second belt drive assembly 22. One second gear drive assembly 21a includes a meshing first bevel gear 221 and a second bevel gear 222, the diameter of the first bevel gear 221 being twice the diameter of the second bevel gear 222; another second gear drive assembly 21b includes a meshing third gear 223 and a fourth gear 224, the diameter of the third gear 223 being twice the diameter of the fourth gear 224. The second bevel gear 222 and the third gear 223 are coaxially arranged. The second belt drive assembly 22 includes a third synchronous pulley 221, a fourth synchronous pulley 223, and a second synchronous belt 224 wound around the third synchronous pulley 221 and the fourth synchronous pulley 223, the diameter of the third synchronous pulley 221 being the same as the diameter of the fourth synchronous pulley 223. The fourth synchronous pulley 223 is coaxially arranged with the second ring pulley 40. The output shaft of the second motor is arranged in a horizontal direction, and the second motor drives the first bevel gear 221 to rotate.

[0046] Similarly, gear transmission has a constant transmission ratio, high transmission efficiency, and compact structure; synchronous belt transmission can transmit over a certain distance. By using a combination of gear transmission and synchronous belt transmission, the second multi-stage transmission mechanism 20 can arrange the components more flexibly.

[0047] The second synchronous belt 224 is at the same height as the first synchronous belt 123.

[0048] In a specific embodiment, such as Figure 3 As shown, the first synchronizing wheel 30 and the second synchronizing wheel 40 are arranged side by side in the left-right direction. The line connecting the center of the first synchronizing wheel 121 and the center of the second synchronizing wheel 122 forms an angle β with the left-right direction, where 5°≤β≤25°.

[0049] like Figure 4 and Figure 5 As shown, the second belt drive assembly 22 also includes a fifth synchronous pulley 222 and a guide pulley 225. The first synchronous pulley 121, the fifth synchronous pulley 222, and the third synchronous pulley 221 are arranged from back to front. The guide pulley 225 is located outside the second synchronous belt 224 and is positioned close to the fifth synchronous pulley 222. Thus, the second synchronous belt 224 first extends towards the first synchronous pulley 121, and then extends towards the second loop pulley 40. The first synchronous pulley 121, the second synchronous pulley 122, the third synchronous pulley 221, the fifth synchronous pulley 222, and the guide pulley 225 are all located at the same height.

[0050] In this way, the first synchronous belt 123 and the second synchronous belt 224 are close to each other, making their structures compact and thus reducing the overall size and space occupied by the first and second belt drive components.

[0051] The rope embroidery device also includes a support assembly 60. The support assembly 60 includes a first frame 62 and a second frame 63 connected to the first frame 62. The first frame 62 can be located on the left or right side of the needle bar frame, and the second frame 63 can be located on the front side of the needle bar frame.

[0052] like Figure 2 As shown, the first frame 62 includes a first accommodating chamber 621 for housing a second gear transmission assembly 21a and a second accommodating chamber 622 for housing the first and second belt transmission assemblies and another second gear transmission assembly 21b. The first motor is located in the space between the first accommodating chamber 621 and the second accommodating chamber 622. This arrangement allows the first multi-stage transmission mechanism 10 and the second multi-stage transmission mechanism 20 to be mounted on the first frame 62, resulting in a compact structure and helping to save space.

[0053] The second frame 63 is used to mount the tensioning mechanism 50. The tensioning mechanism 50 includes a first tensioning component 51 and a second tensioning component 52 located at the same height. The first tensioning component 51 and the second tensioning component 52 are parallel to a common plane and are arranged in a direction perpendicular to the common plane. The first tensioning component 51 is used to tension the rope or ribbon entering the first looper 30, and the second tensioning component 52 is used to tension the rope or ribbon entering the second looper 40.

[0054] The common plane of the first frame 62 and the second frame 63 is located on the left or right side of the needle bar frame and on the front side of the needle bar frame. The common plane is inclined relative to the needle bar frame and forms an angle α with the front and rear direction, where 5°≤α≤45°.

[0055] In practical applications, such as Figure 3 As shown, needles A (No. 1), B (No. 2), and C (No. 3) are arranged sequentially from left to right on the needle bar frame, with needles A, B, and C close to the second frame 63. Because the shared plane forms an angle α with the front-to-back direction, the space between the second frame 63 and the needle bar frame is increased, which helps the operator thread the embroidery thread onto needles A, B, and C.

[0056] Furthermore, the orthographic projection of the first tensioning component 51 on the projection surface is positioned away from the needle bar holder, while the orthographic projection of the second tensioning component 52 on the projection surface is positioned close to the needle bar holder, wherein the projection surface is coplanar with the common plane.

[0057] Figure 3This is a top-view schematic diagram of the rope embroidery device. From this top-view perspective, the first tensioning component 51 is positioned forward, and the second tensioning component 52 is positioned backward. Compared to a top-view configuration where the first tensioning component 51 is positioned backward and the second tensioning component 52 is positioned forward, or where they are aligned, the arrangement of the first tensioning component 51 and the second tensioning component 52 in this embodiment results in a compact structure, which helps save space. Furthermore, from a top-view perspective, there are no obstructions on the front side of the first tensioning component 51, making it convenient for the operator to wrap the rope or ribbon around it for the first time, without being affected by the second tensioning component 52.

[0058] The second accommodating chamber 622 has two rope clamping pieces 70 at its bottom, which are respectively positioned near the first looping wheel 30 and the second looping wheel 40. After the rope embroidery is completed, the rope or ribbon ends on the first and second looping wheels can be clamped onto the rope clamping pieces 70 to prevent the rope or ribbon ends from accidentally detaching from the looping wheels.

[0059] The support assembly 60 further includes a connecting plate 61 and a vertical telescopic member 64. The movable end of the vertical telescopic member 64 can reciprocate in the vertical direction. The movable end of the vertical telescopic member 64 is connected to the connecting plate 61, and the first frame 62 is connected to the connecting plate 61. The vertical telescopic member 64 can be an electric push rod, a hydraulic push rod, a pneumatic push rod, etc., and this embodiment is not limited to this. The vertical telescopic member 64 is used to adjust the spatial position of the first multi-stage transmission mechanism 10 and the second multi-stage transmission mechanism 20 in the vertical direction.

[0060] The connecting plate 61 includes a horizontal portion 612 and a vertical portion 611. One of the horizontal portion 612 and the vertical portion 611 has a first elongated hole in the front-back direction, and the other has a second elongated hole in the left-right direction. The first elongated hole in the front-back direction is used to adjust the spatial position of the first multi-stage transmission mechanism 10 and the second multi-stage transmission mechanism 20 in the front-back direction; the second elongated hole in the left-right direction is used to adjust the spatial position of the first multi-stage transmission mechanism 10 and the second multi-stage transmission mechanism 20 in the left-right direction.

[0061] In this way, the spatial positions of the first multi-stage transmission mechanism 10 and the second multi-stage transmission mechanism 20 can be finely adjusted so that there is a preset distance between the ring-forming wheel and the table of the computer embroidery machine.
