Description

Technical Field

[0001] The invention relates to the technical field of embroidery machines, and in particular to an embroidery bead feeding mechanism. Background Art

[0002] With the progress of society and the improvement of living standards, people's demand for objects is not only limited to functional use, but also aesthetics greatly affects people's choices. The most intuitive manifestation is in clothing and household textiles. People are more and more particular about the patterns on clothing and textiles. In order to attract consumers to buy, tiny embroidery beads are sewn onto clothes as decorative patterns to make the patterns three-dimensional and aesthetically pleasing. In order to better enrich the color and layering of the patterns, it is necessary to use embroidery beads of multiple colors and specifications at the same time. In order to improve production efficiency, technicians in this field have developed a variety of multi-color embroidery machines with color-changing devices. Limited by the structure, most of the existing multi-color embroidery machines can usually only be used for multi-color and multi-specification embroidery beads with small height differences. There are also a few embroidery machines that can be used for embroidery beads of different heights and specifications, such as Chinese patents CN114016221A, CN113846441A, CN116377668A, etc.

[0003] Chinese patent CN114016221A discloses a method for conveying beads of various heights. An adjustment plate that can slide to or leave the bead feeding area is provided on the bead feeding area of ​​the bottom plate of the bead feeding mechanism, and a sliding driver is provided to drive the adjustment plate to slide. The present invention provides an adjustment plate that cooperates with the bead clamp on the bottom plate, and a sliding driver that drives the adjustment plate to slide to or leave the bead feeding area. The sliding driver drives the adjustment plate to slide into the bead feeding area so that the adjustment plate forms the bottom surface of the beads held by the bead feeding clamp, so that the bead clamp can relatively stably clamp beads with a smaller height. Alternatively, the sliding driver drives the adjustment area so that the bottom plate forms the bottom surface of the beads held by the bead feeding clamp, and the depth of the bottom plate is increased, so that it can be used to clamp beads with a higher height. The present invention has a simple structure and can adapt to conveying beads of various heights compared to the existing bead feeding structure. In the above scheme, the bottom plate needs to be processed with transversely distributed guide grooves, which makes the bottom plate processing difficult, and when working, the adjustment plate needs to slide left and right, so that the above bead feeding mechanism requires a larger installation space.

[0004] Chinese patent CN113846441A discloses a multi-color embroidery bead feeding mechanism, comprising a base, an active pulley that slides forward and backward, a bead feeding elastic clamp, and a bead passing block located above the bead feeding elastic clamp and capable of moving left and right, the bead passing block having at least two lower bead holes arranged side by side, the side of the bead feeding elastic clamp having at least one layer of side grooves, all of which are used to divide the bead receiving opening of the bead feeding elastic clamp into at least two sections, and the corresponding side grooves can be matched with corresponding baffles to adjust the bead receiving depth of the bead receiving opening to meet the needs of bead feeding of embroidery beads of different heights; the present invention also provides a method for using a multi-color embroidery bead feeding mechanism; the present invention can realize the feeding of embroidery beads of various lengths without stopping the machine, and the structure is compact, and the bead feeding elastic clamp will not be suspended during the working process, so as to avoid deformation of the bead feeding elastic clamp and affect the continuity of bead feeding. In the above scheme, the thickness of the bead feeding elastic clamp is relatively large, and the structure of the bead feeding elastic clamp is complex, and during the working process, the baffle needs to slide left and right, so that the above mechanism requires a large installation space.

[0005] Chinese patent CN116377668A discloses a multi-bead feeding device, including a lower section for conveying beads that can cooperate with an upper section. The positioning hole tubes are arranged on the seat body in sequence in front and back, and in sequence in the transverse direction. A sufficient transverse distance is set between two adjacent positioning hole tubes. The seat body can be driven by a sliding driver to make any positioning hole tube enter the position of cooperating with the bead clamp, so that the bead clamp is driven by the driving structure to receive beads from a positioning hole tube at the cooperating position and deliver the beads to the bead embroidery station. Since the adjacent positioning hole tubes are arranged with a sufficient transverse distance, the beads conveyed in the rear positioning hole tube will not interfere with and collide with the beads in the front positioning hole tube, and the requirements for the beads of each bead feeder are relatively low, and beads with low precision requirements can be conveyed, which greatly saves costs. The pad and the driver of the pad that change the height of the bead feeding base surface on the bottom plate are omitted, and the width of the bottom plate can be effectively reduced, so that it can cooperate with other mechanisms such as bead feeding mechanisms and sheet feeding mechanisms and the same machine needle. During operation, the bead receiving station will be different according to the different positioning hole tubes of the dropped beads, which will cause the stroke of the bead clamp to be different, making the control difficult, and increasing the stroke of the bead clamp will reduce the work efficiency. Summary of the invention

[0006] The invention provides an embroidery bead feeding mechanism which has a simple structure and requires a small installation space.

[0007] To achieve the above object, the present invention provides the following technical solutions: A bead feeding mechanism comprises a base and a color changing mechanism on which an active pulley and a bead feeding elastic clamp are installed. The movement of a bead passing block of the color changing mechanism is controlled so that the embroidery beads located in the corresponding bead passing holes of the bead passing block fall into the bead receiving opening of the bead feeding elastic clamp. The mechanism also comprises a bead receiving depth adjustment mechanism linked with the bead passing block. The bead receiving depth adjustment mechanism is used to limit the position of the bottom surface of the embroidery beads relative to the bead receiving opening to realize the feeding of long and short beads.

[0008] Furthermore, the bead receiving depth adjustment mechanism includes an adjustment block, and the adjustment block is located below the bead receiving opening.

[0009] Furthermore, the bead receiving depth adjustment mechanism also includes an elastic floating frame arranged on the base and connected to the adjustment block, and the adjustment block is driven to move relative to the bead receiving port by driving the elastic floating frame.

[0010] Furthermore, the bead receiving depth adjustment mechanism also includes a driving pressure rod that moves synchronously with the bead passing block, and the driving pressure rod is in conflict with the elastic floating frame.

[0011] Furthermore, the driving pressure rod conflicts with the guide slope of the elastic floating frame.

[0012] Furthermore, the driving pressure rod is provided with a roller in contact with the guide slope.

[0013] Furthermore, two sliding shafts are connected to the elastic floating frame, the sliding shafts are slidably connected to the base, and an elastic member is provided between the elastic floating frame and the base.

[0014] Furthermore, the elastic member is a spring sleeved on the sliding shaft.

[0015] Furthermore, the bead receiving depth adjustment mechanism also includes a swing arm, one end of which is in contact with the elastic floating frame, and the swing arm swings to drive the elastic floating frame to move and drive the adjustment block to move relative to the bead receiving port.

[0016] Furthermore, one end of the swing arm contacts the lower surface of the elastic floating frame, and the swing arm is lifted up after enabling the elastic floating frame to overcome the elastic force acting on the elastic floating frame (31); or one end of the swing arm contacts the upper surface of the elastic floating frame, and the swing arm is pressed down after enabling the elastic floating frame to overcome the elastic force acting on the elastic floating frame.

[0017] Furthermore, the swing arm can move synchronously with the bead passing block; or the swing arm can move asynchronously with the bead passing block.

[0018] Furthermore, a detachable driving shaft arranged on the color-changing mechanism is movably connected to a fork opening located on the other end of the swing arm.

[0019] It can be seen from the above technical scheme that the advantages of the present invention are: by setting a lifting and lowering adjustment block at the bead receiving station of the base to adjust the bead receiving depth, the structure is simple, and the installation space required for the embroidery bead feeding mechanism is small; and when the color changing mechanism is separated from the bead receiving depth adjustment mechanism, embroidery work can be carried out with embroidery beads of the same height and different colors.

[0020] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1 refer to Figures 1 to 7 To further explain this application, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The embroidery bead feeding mechanism shown in the figure includes a base 4 equipped with an active pulley 5 and a bead feeding elastic clamp 6, a color changing mechanism 2 and a bead receiving depth adjustment mechanism 3. The embroidery beads in the corresponding bead passing holes 272 of the bead passing block 27 are made to fall into the bead receiving opening 62 of the bead feeding elastic clamp 6 to realize the embroidery bead switching by controlling the movement of the bead passing block 27 of the color changing mechanism 2. The bead receiving depth adjustment mechanism 3 is connected to the bead passing block 27. The bead receiving depth adjustment mechanism 3 is linked with the bead passing block 27. When the bead passing block 27 moves, the bead receiving depth adjustment mechanism 3 moves with the bead passing block 27. The bead receiving depth adjustment mechanism 3 is used to limit the position of the bottom surface of the embroidery beads relative to the bead receiving opening 62 to realize the feeding of long and short beads. Specifically, the bead receiving depth adjustment mechanism 3 includes an adjustment block 321, and the adjustment block 321 is located below the bead receiving opening 62 The bottom surface of the base 4 is provided with a recessed portion corresponding to the bead receiving position, and the adjusting block 321 can be raised and lowered in the recessed portion, and the top surface of the adjusting block 321 can contact the bottom surface of the embroidery beads. The change in the position of the top surface of the adjusting block 321 relative to the bead receiving opening 62 can make the middle parts of embroidery beads of different lengths be clamped by the bead receiving opening 62, which is convenient for the bead feeding elastic clamp 6 to transport the embroidery beads. The setting of the recessed portion can accommodate the adjusting block 321 to avoid excessive increase in the thickness of the base 4. The distance between the top surface of the adjusting block 321 and the bead passing block 27 is adjusted by controlling the lifting and lowering of the adjusting block 321, so that embroidery beads of different heights can be stably and accurately transported by the bead feeding elastic clamp 6. The lifting and lowering action of the adjusting block 321 will not increase the volume of the embroidery bead feeding mechanism, so that the occupied space is small and the structure is simple.

[0036] In the present application, preferably, the recessed portion is an adjustment hole 42 provided on the bottom surface of the base 4 , and the adjustment block 321 is provided in the adjustment hole 42 so as to be liftable.

[0037] In the present application, preferably, a bead delivery groove 41 is provided on the bottom surface of the base 4, and the adjustment hole 42 is located on the bottom surface of the bead delivery groove 41, wherein one end of the bead delivery groove 41 extends to the front end surface of the base 4, and the setting of the bead delivery groove 41 enables embroidery beads of different heights to be transported.

[0038] The bead feeding mechanism also includes a bead feeding frame 1 connected to the base 4, and the bead feeding frame 1 is provided with a bead feeding motor 10 and a transmission mechanism 9. The bead feeding motor 10 drives the bead embroidery connecting rod fork 8 to swing through the transmission mechanism 9. The bead embroidery connecting rod fork 8 is connected to the active pulley 5. A cover plate 7 is provided on the bead feeding elastic clamp 6, and a magnet is provided at the bottom of the bead feeding elastic clamp 6. The magnet is used to enable the bead feeding elastic clamp 6 to slide slowly relative to the active pulley 5, and is used to control the bead receiving port 62 of the bead feeding elastic clamp 6 to open or close.

[0039] The color-changing mechanism 2 also includes a bead-changing motor 21 connected to the bead-feeding rack 1, a driving connecting rod 22 connected to the output shaft of the bead-changing motor 21, a mounting plate 24 slidably arranged on the bead-feeding rack 1, and a transmission connecting rod 23 hinged between the mounting plate 24 and the driving connecting rod 22. The bead-passing block 27 is connected to the mounting plate 24. When the bead-changing motor 21 drives the driving connecting rod 22 to rotate, it drives the transmission connecting rod 23 to move. The movement of the transmission connecting rod 23 will drive the mounting plate 24 to slide. The sliding of the mounting plate 24 drives the bead-passing block 27 to move to realize the bead-changing work.

[0040] Specifically, a slider 25 is provided on the mounting plate 24, and a guide rail 26 slidably matched with the slider 25 is provided on the bead feeding frame 1, so that the mounting plate 24 runs smoothly, and further the bead changing process of the bead passing block 27 runs smoothly.

[0041] In an embodiment of the present application, the bead receiving depth adjustment mechanism 3 also includes an elastic floating frame 31 arranged on the base 4 and connected to the adjustment block 321. The elastic floating frame 31 is driven to drive the adjustment block 321 to move relative to the bead receiving port 62. Specifically, the elastic floating frame 31 is driven downward to drive the adjustment block 321 to move downward, so that the distance between the adjustment block 321 and the bead receiving port 62 becomes longer to accommodate the transportation of long embroidery beads; the elastic floating frame 31 is reset to drive the adjustment block 321 to move upward, so that the distance between the adjustment block 321 and the bead receiving port 62 becomes shorter to accommodate the transportation of short embroidery beads.

[0042] Specifically, the adjustment block 321 is detachably connected to the adjustment frame 32 having the adjustment block 321, the bottom surface of the base 4 is provided with a downwardly facing mounting groove, the side surface of the base 4 is provided with a through groove to avoid the connecting portion of the adjustment frame 32, the connecting portion of the adjustment frame 32 is located in the mounting groove, and the above structure is adopted to make the structure of the bead receiving depth adjustment mechanism 3 more compact, and will not excessively increase the thickness of the base 4; the elastic floating frame 31 can be directly driven to rise and fall by connecting with the cylinder; the elastic floating frame 31 can be moved downward by pressing a linear driving mechanism such as a cylinder, an oil cylinder or an electric push rod, and reset by moving upward using an elastic member; the elastic floating frame 31 can realize the lifting and lowering drive of the elastic floating frame 31 through a crank-connecting rod mechanism.

[0043] In the embodiment of the present application, the color-changing mechanism 2 preferably further comprises a driving pressure rod 28 connected to the mounting plate 24. When the driving pressure rod 28 moves, it can move along the guide slope 311 of the elastic floating frame 31 to control the lifting and lowering of the elastic floating frame 31, and then control the lifting and lowering of the adjustment block 321. The color-changing mechanism 2 and the bead receiving depth adjustment mechanism 3 are linked by a mechanical driving structure, which not only makes the structure compact, but also makes the control more convenient. The synchronous action of the bead passing block 27 and the driving pressure rod 28 enables the bead receiving depth at the bead receiving station to be adjusted to match the corresponding embroidery beads while switching the embroidery beads, which can ensure that the embroidery beads are stably and reliably transported.

[0044] In the embodiment of the present application, the driving rod 28 is in conflict with the elastic floating frame 31, specifically, the driving rod 28 is in conflict with the guide slope 311 of the elastic floating frame 31, and preferably, the driving rod 28 is provided with a roller 29 in contact with the guide slope 311. The use of the roller 29 can reduce the contact friction between the driving rod 28 and the elastic floating frame 31, making the bead changing process smoother.

[0045] In the embodiment of the present application, two sliding shafts 33 are connected to the elastic floating frame 31, and the sliding shafts 33 are slidably connected to the corresponding sliding sleeves 34 arranged on the base 4. An elastic member is provided between the elastic floating frame 31 and the base 4 to drive the elastic floating frame 31 to move up and reset.

[0046] In the embodiment of the present application, preferably, the elastic member is a spring 35 sleeved on the sliding shaft 33 .

[0047] In the embodiment of the present application, a bead avoidance groove 271 corresponding to the position of the corresponding bead hole 272 is provided on the bottom surface of the bead passing block 27. The setting of the bead avoidance groove 271 can ensure that the bead feeding elastic clamp 6 is clamped at the center of the embroidery bead, and can prevent the bead feeding elastic clamp 6 from only clamping the upper part of the embroidery bead during the bead feeding process when the embroidery bead is too long, which may easily cause the embroidery bead to fall off due to uneven force during the bead feeding process, and leaking beads. When the bead feeding is completed and the bead is being embroidered, the embroidery bead may also fall off during the embroidery process due to unstable clamping, resulting in leaking beads.

[0048] In the embodiment of the present application, at least two bead passing holes 272 are provided on the bead passing block 27 .

[0049] In the embodiment of the present application, preferably, the higher the height of the embroidery bead, the greater the depth of the embroidery bead avoidance groove 271. When the required embroidery bead height is the largest, the depth of the embroidery bead avoidance groove 271 is also the largest, which can reduce the adjustment stroke of the adjustment block 321 on the one hand, and ensure that the bead feeding elastic clip 6 is clamped at the center of the embroidery bead on the other hand, so that the bead feeding elastic clip 6 can clamp the embroidery bead stably.

[0050] like Figure 6 As shown, the base 4 is also provided with a guide groove 43 which cooperates with the convex shaft of the bead feeding elastic clamp 6 and can limit the stroke position of the bead feeding elastic clamp 6. The base 4 is also provided with a through groove 44 which is located at the rear end of the guide groove 43 and is connected with the guide groove 43. The through groove 44 is mainly used to facilitate broken beads or scattered embroidery beads to fall directly therefrom, that is, to leak beads, so as to avoid the influence of crushed or scattered embroidery beads on embroidery work; the through groove also has a dust removal function.

[0051] like Figure 7 As shown, the bead-feeding elastic clamp 6 is provided with an upwardly extending convex edge 61 at the inner wall of the bead receiving opening 62. The upwardly extending convex edge 61 can increase the depth of the clamping opening of the bead-feeding elastic clamp 6, which is more beneficial for clamping beads with higher heights, and can also be compatible with clamping various types of beads, such as tube beads, bubble beads, etc., and can even clamp round beads.

[0052] Since the present application can simultaneously drive the bead receiving depth adjustment mechanism 3 to perform adjustment during the bead changing process of the color changing mechanism 2, the driving mechanism for driving the bead receiving depth adjustment mechanism 3 is saved, making the structure of the present application compact and simple. Since the bead receiving depth adjustment mechanism 3 only performs lifting and lowering movements, it will not increase the width space required for the present application, and thus the present application will occupy little space during installation.

[0053] Embodiment 2 refer to Figures 8 to 11 To further explain this application, Figure 8 , Fig. 9 , Fig.10 and Fig.11 In the bead feeding mechanism shown, the driving pressure rod 28 and the roller 29 are replaced by the swing arm 36, and the structure of the elastic floating frame 31 is adaptively changed according to the change of the driving structure. The other component structures and assembly relationships of the bead feeding mechanism are the same as those in Example 1.

[0054] In the embodiment of the present application, the swing arm 36 is swingably arranged on the base 4 or the bead feeding rack 1 through a pin shaft, and one end of the swing arm 36 is in contact with the elastic floating rack 31. The swing arm 36 swings to drive the elastic floating rack 31 to move and drive the adjustment block 321 to move relative to the bead receiving port 62, so as to adapt to the use of long and short beads for feeding beads.

[0055] Furthermore, when the swing arm 36 swings, it drives the elastic floating frame 31 to perform lifting movement, thereby controlling the lifting and lowering of the adjustment block 321, wherein the swing arm 36 can be connected to a linear drive mechanism such as a cylinder, an oil cylinder, or an electric push rod to achieve linear drive or drive the swing arm 36 through a rotating drive mechanism to move, thereby adjusting the position of the adjustment block 321.

[0056] In an embodiment of the present application, when the swing arm 36 is used to drive the elastic floating frame 31 to lift up, the spring 35 is used to drive the elastic floating frame 31 to descend and reset; when the swing arm 36 is used to drive the elastic floating frame 31 to press down, the spring 35 is used to drive the elastic floating frame 31 to lift up and reset.

[0057] Specifically, one end of the swing arm 36 abuts against the lower surface of the elastic floating frame 31, and the swing arm 36 lifts up after allowing the elastic floating frame 31 to overcome the elastic force acting on the elastic floating frame 31; or one end of the swing arm 36 abuts against the upper surface of the elastic floating frame 31, and the swing arm 36 presses down after allowing the elastic floating frame 31 to overcome the elastic force acting on the elastic floating frame 31.

[0058] Preferably in the present application, the swing arm 36 abuts against the lower surface of the protrusion of the elastic floating frame 31, and the swing arm 36 swings to drive the elastic floating frame 31 to lift up, and the spring 35 is used to drive the elastic floating frame 31 to descend and reset, and the swing arm 36 causes the elastic floating frame 31 to lift up after overcoming the elastic force acting on the elastic floating frame 31.

[0059] In an embodiment of the present application, the swing arm 36 can move synchronously or asynchronously with the bead passing block 27, wherein when the swing arm 36 moves synchronously with the bead passing block 27, the bead receiving depth at the bead receiving station can be adjusted simultaneously when switching the embroidery beads to match the corresponding embroidery beads, thereby ensuring that the embroidery beads are stably and reliably transported; when the swing arm 36 moves asynchronously with the bead passing block 27 and the swing arm 36 remains stationary, the position of the elastic floating frame 31 will not change, and thus the position of the adjustment block 321 will not change. When the position of the adjustment block 321 is stationary, the present application can be adapted to the use of embroidery beads of different colors with the same height.

[0060] Specifically, the detachable drive shaft 241 arranged on the color changing mechanism 2 is movably connected with the fork opening at the other end of the swing arm 36. When the drive shaft 241 is connected to the color changing mechanism 2, the drive shaft 241 will move synchronously with the bead passing block 27. When the drive shaft 241 moves, it will drive the swing arm 36 to swing reliably. The color changing mechanism 2 and the bead receiving depth adjustment mechanism 3 are linked by a mechanical driving structure, which not only makes the structure compact but also makes the control more convenient. When the drive shaft 241 is removed, the swing arm 36 is separated from the color changing mechanism 2. When the swing arm 36 is not driven, the elastic floating frame 31 maintains a stable state under the action of the spring 35, wherein the drive shaft 241 and the bead passing block 27 are both detachably connected to the mounting plate 24 of the color changing mechanism 2.

[0061] In an embodiment of the present application, the threaded section of the drive shaft 241 is threadedly connected to a nut disposed on the mounting plate 24, or a latching tooth disposed on the drive shaft 241 or a latching arm disposed on the mounting plate 24 is elastically snap-fitted and connected, or a screw is used to pass through the drive shaft 241 and connect it to the mounting plate 24 to achieve detachable installation of the drive shaft 241.
