Description

Technical Field

[0001] One or more embodiments of this disclosure relate to the field of embroidery machine technology, and in particular to a material tray structure for ribbon embroidery, a ribbon embroidery device, and an embroidery machine. Background Technology

[0002] A ribbon embroidery device is used for embroidering ribbons and / or cords. A typical ribbon embroidery device consists of a housing, drive shaft, needle bar, feeding section, presser foot, and thread take-up lever. Current feeding sections use a tray to carry the ribbon, which is mounted on the device's bushing via a mounting bracket. During ribbon embroidery, the needle pierces the fabric, and the thread locks the cord or ribbon from the tray onto the fabric. Moving the embroidery frame at this time moves the cord / ribbon.

[0003] In some related technologies, the mounting bracket has an opening and closing structure. After opening and closing the structure, one end of the connecting shaft on the mounting bracket is exposed, allowing the material tray to be inserted from this end and fitted onto the connecting shaft. Afterwards, closing the opening and closing structure seals the exposed end of the connecting shaft, thus completing the assembly of the material tray and the mounting bracket. This structure is relatively complex and inconvenient for installing and replacing the material tray.

[0004] In some related technologies, the tray is fixed to the mounting frame by a rotating plunger. Although the tray structure is simple, the installation is laborious because the fixing or removal of the tray is achieved by the elastic fit between the rotating plunger and the mounting frame. Furthermore, the installation accuracy of the rotating plunger affects the installation accuracy of the tray on the mounting frame. If there is a positional deviation at both ends of the tray, the tray may be installed at an angle on the mounting frame, or it may even be impossible to install. Utility Model Content

[0005] This disclosure provides one or more embodiments of a material tray structure, a ribbon embroidery device, and an embroidery machine for ribbon embroidery, aimed at solving one or more of the above-mentioned problems and other potential problems.

[0006] Firstly, this disclosure provides a tray structure for ribbon embroidery. The tray structure includes a mounting frame and a tray, with the mounting frame connected to the tray. The mounting frame has slots, and the tray is engaged with tray shafts at both ends, thus confining the tray shafts within the slots. The tray structure for ribbon embroidery according to this disclosure is not only simple in structure and easy to disassemble and replace, but also meets the requirement for rapid and stable rotation of the tray during high-speed ribbon embroidery operations.

[0007] In some embodiments, the tray and the tray shaft are assembled as one unit.

[0008] In some embodiments, the material tray shaft is fixedly mounted on the material tray, or the material tray shaft is rotatably mounted on the material tray.

[0009] In some embodiments, the width of the slot is greater than the diameter of the tray shaft.

[0010] In some embodiments, the card slot is opened downward from the upper edge of the mounting bracket, and the bottom of the card slot is connected to the slot body portion which is vertically arranged or offset toward the rotation center of the tray.

[0011] In some embodiments, the mounting bracket is provided with a limiting member for preventing the tray shaft from disengaging from the slot.

[0012] In some embodiments, the limiting member is an elastic limiting member.

[0013] In some embodiments, the elastic limiting member is mounted on the mounting bracket, and the free end of the elastic limiting member at least partially interferes with the slot, such that the width of the channel formed between the slot wall and the free end of the elastic limiting member is smaller than the diameter of the spool shaft, thereby restricting the spool shaft from disengaging from the slot.

[0014] In some embodiments, the mounting bracket includes a first mounting bracket and a second mounting bracket, the first mounting bracket being used to mount on the head of a tape embroidery machine, the second mounting bracket being connected to the first mounting bracket, and a slot being formed on the second mounting bracket.

[0015] In some embodiments, the second mounting bracket has at least two mounting arms, with the tray shafts at both ends of the tray mounted between two adjacent mounting arms.

[0016] Secondly, embodiments of this disclosure also provide a ribbon embroidery apparatus. The apparatus includes a ribbon embroidery machine head and a material tray structure for ribbon embroidery as described in the first aspect.

[0017] In some embodiments, the mounting bracket is installed outside the bushing of the tape embroidery machine head, and the tape embroidery machine head is provided with a rotating mechanism that drives the bushing to rotate.

[0018] Thirdly, embodiments of this disclosure also provide an embroidery machine. This embroidery machine includes the ribbon embroidery apparatus described in the second aspect. Attached Figure Description

[0025] Preferred embodiments of the present disclosure will be described in detail with reference to the drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure is more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] The term "comprising" and variations thereof as used herein are intended to mean "including but not limited to". The term "or" as used herein is intended to mean "and / or". The term "based on" is intended to mean "based, at least in part, on". The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "upper", "lower", "front", "back", and the like, indicate the orientation or position of the word as shown in the drawings, and are used only for the convenience of describing the principles of the present disclosure, and do not indicate or imply that the elements referred to must have a particular orientation, be constructed or operated in a particular orientation, and therefore should not be construed as limiting the present disclosure.

[0027] As mentioned above, the tray is mounted on the disc-braid embroidery device through the mounting frame, and the tray serves as a feeding part to deliver the braid for locking the braid on the embroidery with the face thread during the disc-braid embroidery operation. In order to facilitate the replacement of the braid, the tray and the mounting frame are generally designed as a detachable structure. At the same time, it is also necessary to consider that the mounted tray can still stably deliver the braid during the rapid rotation process during the disc-braid embroidery operation.

[0028] In some related technologies, the mounting frame adopts a closed structure. When a tray needs to be installed, the mounting frame is opened through an opening and closing structure, so that the connecting shaft is exposed, the tray can pass through the installation, and then the opening and closing structure is closed, so that the exposed connecting shaft and the opening and closing structure form a closed structure again. In this way, the opening and closing structure can be opened and closed according to the assembly needs to realize the installation or disassembly of the tray. Moreover, when the tray rotates quickly, the tray will not be separated from the mounting frame, and the embroidery material can be stably conveyed. However, the tray structure is relatively complex, and the opening and closing structure needs to be designed for use. On the one hand, the opening and closing structure needs to be specially designed and accurately assembled, so that after the tray is installed on the connecting shaft, the opening and closing structure can be effectively closed to ensure that the tray will not be separated from the connecting shaft due to the opening of the opening and closing structure when rotating. On the other hand, the opening and closing structure needs to be repeatedly opened and closed for each disassembly and assembly of the tray, which is complicated and inconvenient. Especially when there are multiple tray embroidery devices on one embroidery machine, the disassembly and assembly are complicated and inefficient.

[0029] In view of this, according to the embodiments of the present disclosure, a tray structure for tray embroidery is provided, which is simple in structure and convenient to disassemble and assemble. The mounting frame of the tray structure does not need to be designed with an opening and closing structure. The tray can be quickly installed by clamping the tray shaft at both ends into the clamping groove on the mounting frame. The tray can also be quickly disassembled by separating the tray shaft at both ends from the clamping groove. Further, since the clamping groove limits the movement space of the tray shaft, even if the tray rotates quickly during the tray embroidery operation, the tray is not easy to separate from the clamping groove of the mounting frame, and the embroidery material can be stably conveyed.

[0030] Figure 1 A structural diagram of a tray structure 10 for tray embroidery according to an embodiment of the present disclosure is shown. As shown in the figure, Figure 1 The tray structure 10 can include a tray 102 and a mounting frame 101. The tray 102 is detachably connected to the mounting frame 101. The mounting frame 101 is provided with a clamping groove 101-1. The tray 102 is clamped into the clamping groove 101-1 through the tray shaft 103 at both ends, and the tray shaft 103 is limited in the clamping groove 101, so that the tray can rotate stably during the tray embroidery operation, and the tray can be stably conveyed. In the example shown in the figure, there are two trays, which are arranged on both sides of the mounting frame 101. In some embodiments, one tray can be arranged on one side of the mounting frame. In some embodiments, three or more trays can be arranged, and the number of trays can be arranged according to needs, and the trays are evenly distributed on the mounting frame.

[0031] In some embodiments, the slot width of the clamping groove 101-1 is greater than the diameter of the tray shaft 103, so that the tray shaft can be clamped into the clamping groove 101.

[0032] In order to prevent the tray shaft 103 from separating from the clamping groove 101-1, the clamping groove 101-1 can be provided as an inclined through groove, for example Figure 1The form shown is not limited to this form. In addition, the card slot 101-1 can also be set as a non-through slot, can be a multi-layer rotating slot or a curved slot. Based on the principle that the tray shaft will not be separated from the card slot due to the rotation centrifugal force during the rotation of the tray, the card slot can be designed as needed, which is not limited to Figure 1 The form of the card slot shown. In some embodiments, the slot of the card slot 101-1 can be opened at an edge (such as a lower edge, a side edge, an upper edge, etc.) of the mounting frame, and the overall slot body between the slot opening and the slot bottom can be connected in a straight-through structure, or in a rotating structure or a curved structure.

[0033] In some embodiments, when the slot opening of the card slot 101-1 is located at the upper edge of the mounting frame 101, the slot body part connected to the slot bottom can be vertically arranged or arranged to deviate from the rotation center of the tray 102 (the rotation center when the tray rotates during the embroidery work of the tray). When vertically arranged, the overall slot body between the slot opening and the slot bottom can be a non-through slot or a straight-through slot (a corresponding card limiting structure can be provided to prevent the tray shaft from being separated from the card slot in the vertical direction during rotation). When arranged to deviate from the rotation center of the tray 102, the overall slot body between the slot opening and the slot bottom can be a straight-through slot or a non-through slot. In an example, the card slot 101-1 is opened downward from the upper edge of the mounting frame 101, the overall slot body between the slot opening and the slot bottom is an inclined straight-through slot, and the slot opening is offset from the slot bottom in the vertical direction relative to the rotation center of the tray 102. The card slot structure in this example is simple and facilitates quick assembly. In Figure 1 In the example, the mounting frame 101 is provided with the card slot 101-1 with the slot opening upward, the part of the mounting frame 101 for mounting the tray shaft 103 is in a hook-shaped structure (depending on the setting position and shape of the card slot, the part of the mounting frame 101 for mounting the tray shaft 103 is not limited to the hook-shaped structure), the tray shaft 103 is clamped into the card slot 101-1 and is limited by the hook-shaped structure in the vertical direction, so that the tray shaft 103 is not easy to be separated from the card slot 101-1 in the vertical direction.

[0034] In some embodiments, the tray shaft 103 and the tray 102 are pre-assembled into an integrated whole, and then the integrated assembled tray 102 is clamped into the two card slots 101-1 on the mounting frame 101 through the two tray shafts 103 at the ends, to realize the mounting of the tray 102 and the mounting frame 101. Accordingly, the tray can be disassembled from the mounting frame 101 by separating the two tray shafts 103 at the ends from the two card slots 101-1 on the mounting frame 101. After disassembly, the integrated structure of the tray shaft 103 and the tray 102 can be seen. In other embodiments, the tray shaft 103 is integrally formed with the tray 102, and at this time the tray shaft 103 is fixed relative to the tray 102.

[0035] Figure 2A structure diagram of the tray 102 and the tray shaft 103 assembled as a whole is shown. In some embodiments, the tray shaft 103 is fixed on the tray 102. In some embodiments, the tray shaft 103 is rotatably arranged on the tray 102. In this way, the tray 102 is movable relative to the tray shaft 103 and can rotate circumferentially.

[0036] In some embodiments, the tray shaft 103 can be a whole shaft, which penetrates the tray 102 at both ends and is fixed or rotatably connected with the tray. In some embodiments, the tray shaft 103 can be two segmented shafts, which are arranged at both ends of the tray respectively, and the shaft centers of the two segmented shafts are located on the same axis.

[0037] In some embodiments, the part of the tray shaft 103 that extends out of both ends of the tray is used to be clamped into the clamping groove 101-1, and the part that does not extend out is used to wind the tape. In some embodiments, a rotating shaft is further arranged outside the tray shaft, the diameter of the rotating shaft is smaller than that of the tray shaft, and the two disc surfaces of the tray are connected through the rotating shaft. The tray shaft can be a whole shaft, which penetrates the rotating shaft and extends out of the disc surfaces at both ends of the tray, or can be two segmented shafts, which are arranged at both ends of the rotating shaft and located outside the disc surfaces at both ends of the tray. The rotating shaft is used to wind the tape.

[0038] In some embodiments, the tray 102 can be composed of two disc surfaces and a rotating shaft / tray shaft connecting the disc surfaces. In some embodiments, the tray 102 can be composed of a columnar disc body.

[0039] Figure 3 A structure diagram of the mounting frame 101 is shown. The mounting frame 101 can include a first mounting frame 101-2 and a second mounting frame 101-3. The first mounting frame 101-2 is used to mount the tray structure on the head of the disc tape embroidery machine. The second mounting frame 101-3 is connected with the first mounting frame 101-2, and the clamping groove 101-1 is arranged on the second mounting frame 101-3. In some embodiments, the first mounting frame 101-2 and the second mounting frame 101-3 are arranged separately and are fixed by a fixing member. In some embodiments, the first mounting frame 101-2 and the second mounting frame 101-3 are a one-piece frame structure.

[0040] In some embodiments, the second mounting frame 101-3 has at least two mounting arms 101-3A and 101-3B, and one clamping groove is arranged on each side of the two mounting arms 101-3A and 101-3B. The tray shaft 103 at both ends of the tray 102 can be arranged between the two adjacent mounting arms 101-3A and 101-3B, so that the second mounting frame 101-3 can mount at least one tray. In an example, the second mounting frame 101-3 has four mounting arms, two mounting arms 101-3A and 101-3B are arranged on the same side to mount one tray 102, and the other two mounting arms are arranged on the same side to mount another tray.

[0041] In some embodiments, the second mounting frame can be a whole bracket having at least two mounting arms. In some embodiments, the second mounting frame can include a plurality of split brackets. In an example, a split bracket has mounting arms on both sides, and two split brackets have two mounting arms on the same side for mounting a tray. In another example, a split bracket has one mounting arm, and when there are four split brackets, two split brackets have two mounting arms for mounting a tray.

[0042] In some embodiments, the first mounting frame can be a whole bracket having a gap in the center allowing the shaft sleeve on the disc embroidery device to pass through. In some embodiments, the first mounting frame can be a plurality of split brackets for mounting the split second mounting frame outside the shaft sleeve.

[0043] In order to more clearly describe the application environment of the tray structure 10 in the disc embroidery device, the following will be described in combination with Figure 4 The part structure of the disc embroidery device is described in detail. Figure 4 A perspective structural diagram of a disc embroidery device 30 containing the above-mentioned tray structure 10 according to an embodiment of the present disclosure is shown.

[0044] Figure 4 The disc embroidery device 30 shown in the above-mentioned embodiment can at least include a disc embroidery head 40 and the above-mentioned tray structure 10. The disc embroidery head 40 can include a machine shell, a needle bar portion and its driving mechanism, a presser foot portion and its driving mechanism, etc. The needle bar on the needle bar portion vertically passes through the machine shell, and the needle bar is sequentially sleeved with a presser foot sleeve and a shaft sleeve 41. The tray structure 10 is fixed on the shaft sleeve 41. For example, the mounting frame 101 of the tray structure 10 is mounted outside the shaft sleeve 41.

[0045] The disc embroidery device 30 can further include a rotating mechanism for driving the rotation of the shaft sleeve 41. The rotating mechanism can be a rotating mechanism for driving the synchronous rotation of the tray 102 and the presser foot connected to the presser foot sleeve, or a rotating mechanism for driving the rotation of the tray 102 independently of the presser foot, for example, refer to the prior application patent CN113584749B or other independent driving modes.

[0046] Through the above-mentioned embodiments, the present disclosure can ensure the stable conveying of the belt material during the rotation of the tray by redesigning the tray structure 10, while simplifying the tray structure and the mounting method. In addition, the design simplifies the difficulty of mounting the tray and reduces the requirement for the assembly ability of the mounting personnel, further improving the disassembly and assembly efficiency.

[0047] It should be understood that the tray structure of the above-mentioned embodiments is only exemplary. Now referring to Figure 5 The embodiment of one of the other structures is described in more detail. Figure 5A structural schematic of a tray structure 20 for disc band embroidery according to another embodiment of the present disclosure is shown. The tray structure 20 comprises a mounting frame 201 and a tray 202. The mounting frame 201 is provided with a clamping groove 201-1, and the tray 202 is clamped into the clamping groove 201-1 by means of the tray shafts 203 at both ends and is limited by the clamping groove 201-1 and is not easy to be separated from the clamping groove 201-1. Figure 5 Examples and Figure 1 The difference between examples is that the mounting frame 201 is provided with a limiting piece 204 for further limiting the tray shaft 203 from being separated from the clamping groove 201-1.

[0048] In some embodiments, the limiting piece is an elastic limiting piece which is installed on the mounting frame 201 and has a free end which at least partially interferes with the clamping groove 201-1, so that the channel formed between the groove wall of the clamping groove 201-1 and the free end of the elastic limiting piece has a width smaller than the diameter of the tray shaft 203, so as to limit the tray shaft 203 from being separated from the clamping groove 201-1. The limiting piece 204 can block the path through which the tray shaft 203 can be separated from the clamping groove 201-1, so as to avoid the tray shaft 203 from being separated from the groove bottom to the groove opening. In addition, the tray shaft 203 can be more gently restored to the original position under the elastic property of the limiting piece 204.

[0049] In some examples, the elastic limiting piece 204 can be fixed on the side surface of the mounting frame 201, which can be the outer side surface or the inner side surface, and the acting end of the elastic limiting piece 204 can be arranged on the side surface of the mounting frame and partially or completely block the clamping groove 201-1, or can extend into the clamping groove 201-1. In some examples, the elastic limiting piece 204 can be fixed on the groove wall of the clamping groove 201-1, and the acting end thereof can be located in the clamping groove 201-1 and can extend to the other groove wall of the clamping groove 201-1 or extend towards the other groove wall of the clamping groove 201-1.

[0050] In some examples, the acting end of the elastic limiting piece 204 can be in clearance fit with the tray shaft 203 or can be in contact with the tray shaft 203. In some examples, the acting end of the elastic limiting piece can be an arc-shaped acting end, which is convenient for acting on the tray shaft 203 which is about to be separated from the groove bottom.

[0051] In some examples, the elastic limiting piece 204 can be a spring. As shown in Figure 5 one end of the spring (which can also be other positions of the spring except the end portion) is fixed on the mounting arm of the mounting frame 201, and the other end is the acting end and partially blocks the clamping groove 201-1.

[0052] In some examples, the two sides of the mounting frame 201 are provided with elastic limit members 204 at the tray shafts 203 corresponding to the two ends of each tray 202, which can be installed on the two mounting arms 201-3A, 201-3B of the second mounting frame 201-3. In this way, the tray shafts 203 at the two ends of the tray 202 can be stably limited, avoiding the situation that one end of the tray shaft 203 is separated from the clamping groove 201-1 and the other end of the tray shaft 203 is still in the clamping groove 201-1.

[0053] In some embodiments, the limit member can also be a non-elastic pin shaft, which is configured in a switch form on the mounting frame. In an example, the pin shaft is fixed on the mounting frame, and after the tray 202 is installed on the mounting frame 201, the pin shaft is rotated to partially or completely block the clamping groove 201-1. Alternatively, the pin shaft is rotated to cooperate with the mounting frame to form a latch that completely blocks the clamping groove 201-1. In this way, the pin shaft that blocks the clamping groove 201-1 can block the tray shaft 203 from being separated from the groove bottom to the groove opening.

[0054] In addition, the tray structure 20 can also refer to Figure 4 The tray structure 20 is installed on a disc and belt embroidery device. The disc and belt embroidery device can at least include a disc and belt embroidery head and the above-mentioned tray structure 20. The tray structure 20 is fixed on the shaft sleeve of the disc and belt embroidery head. For example, the mounting frame 201 of the tray structure 20 is installed outside the shaft sleeve.

[0055] The embodiments of the present disclosure also provide an embroidery machine, which includes an embroidery frame and a plurality of embroidery machine heads. The plurality of embroidery machine heads includes a plurality of machine heads of flat embroidery devices and a plurality of machine heads of disc and belt embroidery devices. The disc and belt embroidery device can adopt the disc and belt embroidery device provided with the tray structure 10 or 20. The needle bars of the plurality of machine heads (flat embroidery devices) are synchronously moved by a main shaft. The main shaft is also in transmission connection with a cam shaft of the disc and belt embroidery device, and then drives the cam and the connecting rod mechanism to realize the movement of the needle bar of the disc and belt embroidery device by the power of the main shaft. When the disc and belt embroidery device and the flat embroidery device are jointly arranged on one computer embroidery machine, the problem of mechanical wear and loose thread caused by the disc and belt embroidery device moving with the flat embroidery device during the operation of the flat embroidery device is avoided. The disc and belt embroidery device further includes a separation mechanism, so that the disc and belt embroidery device can be separated from the main shaft and stopped from rotating during the operation of the flat embroidery device.

[0056] The above-described embodiments are merely preferred embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements to the technical solutions of the present disclosure made by those of ordinary skill in the art should fall within the protection scope of the claims of the present disclosure.
