Description

Technical Field

[0001] The utility model relates to the field of embroidery machines, in particular to a feeding device for an embroidery machine. Background Art

[0002] For an embroidery machine for gold embroidery or bead tube embroidery, it is necessary to send gold pieces or bead tubes to the working needle position through a feeding device. The feeding device is provided with a feeding mechanism for conveying the material piece and a cutting knife mechanism for cutting the material piece.

[0003] There are usually two ways for the feeding mechanism and the cutting knife mechanism in the prior art:

[0004] 1. The feeding mechanism and the cutting knife mechanism are respectively driven by two motors. In this way, not only does the number of motors increase, resulting in an increase in the cost of the feeding device, but also the two motors occupy more space, making the volume of the feeding device larger, and at the same time increasing the installation difficulty; 2. The feeding mechanism and the cutting knife mechanism share a motor. The motor is provided with a driving swing rod, and the driving swing rod is provided with two driving parts. The feeding mechanism and the cutting knife mechanism are respectively driven by different driving parts to move. However, this leads to the complexity of the driving swing rod and increases the processing cost of the driving swing rod. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and propose a feeding device for an embroidery machine, which solves various deficiencies existing in the existing feeding device for an embroidery machine.

[0006] In order to achieve the above technical objectives, a feeding device for an embroidery machine proposed by the utility model includes a frame and a first feeding mechanism, a cutting knife mechanism, and a first driving mechanism provided on the frame. The first feeding mechanism includes a first fork that can move back and forth. The cutting knife mechanism includes a knife rod rotatably provided at the bottom of the frame and a cutting knife provided at the front end of the knife rod. The first driving mechanism includes a first motor and a swing rod driven by the first motor. The swing rod has a first end actuated by the first motor and a second end away from the first end. The swing rod is provided with a cylindrical driving part at the second end. The axial direction of the driving part is substantially perpendicular to the swinging direction of the swing rod. The swing rod swinging in the first direction acts on the first feeding mechanism through the driving part to make the first fork move. The swing rod swinging in the second direction acts on the cutting knife mechanism through the driving part to make the knife rod drive the cutting knife to rotate. The first direction is opposite to the second direction.

[0007] Preferably, the driving part is rotatably provided at the second end of the swing rod through a pin shaft.

[0008] Preferably, the rotation center line of the driving part coincides with its central axis.

[0009] Preferably, the driving part is a roller or a bearing.

[0010] Preferably, the driving part is fixedly arranged at the second end of the swing rod.

[0011] Preferably, the cutter mechanism further includes a limiting block arranged at the rear end of the cutter bar, a driving rod rotatably hinged to the frame, a pull rod with one end connected to the limiting block and the other end connected to the driving rod, and a return spring for driving the cutter bar to rotate back to its original position. The return spring is connected to the limiting block, and the connection points of the return spring and the pull rod with the limiting block are respectively located on opposite sides of the cutter bar. The swing rod swinging in the second direction enables the driving part to cooperate with the driving rod, so that the driving rod drives the cutter bar to rotate through the pull rod and the limiting block, and the rotating cutter bar deforms the force of the return spring.

[0012] Preferably, the cutter has a cutting edge, the pull rod and the cutting edge are located on opposite sides of the cutter bar, and the swing rod swinging in the second direction makes the pull rod move upward through the cooperation of the driving part and the driving rod, so that the pull rod drives the cutter to swing downward through the limiting block and the cutter bar; or, the cutter has a cutting edge, the pull rod and the cutting edge are located on the same side of the cutter bar, and the swing rod swinging in the second direction makes the pull rod move downward through the cooperation of the driving part and the driving rod, so that the pull rod drives the cutter to swing downward through the limiting block and the cutter bar.

[0013] Preferably, the first feeding mechanism further includes a first connecting rod hinged to the frame. The first fork is connected to one end of the first connecting rod, and a first torsion spring is arranged at the connection point. The other end of the first connecting rod can cooperate with the driving part. The swing rod swinging in the first direction drives the first fork to move through the cooperation of the driving part and the first connecting rod and deforms the first torsion spring.

[0014] Preferably, the embroidery machine feeding device further includes a second driving mechanism and a second feeding mechanism. The second feeding mechanism includes a second connecting rod and a second fork. One end of the second connecting rod is actuated by the second driving mechanism, and the other end of the second connecting rod is connected to the second fork. The second connecting rod actuated by the second driving mechanism drives the second fork to move.

[0015] Preferably, the second driving mechanism includes a second motor arranged below the first motor, and one end of the second connecting rod is sleeved on the motor shaft of the second motor; or, the second driving mechanism includes a second motor and a transmission structure. The second motor is arranged above the first motor, one end of the second connecting rod is hinged to the frame, the transmission structure is arranged between the motor shaft of the second motor and one end of the second connecting rod, and the second motor actuates the second connecting rod through the transmission structure.

[0016] After adopting the above technical solutions, the utility model has the following beneficial effects.

[0017] 1. The utility model proposes an embroidery machine feeding device, which drives the first feeding mechanism and the cutter mechanism to move respectively through a cylindrical driving part, so that there is no need to provide multiple driving parts on the swing rod, which simplifies the design and assembly difficulty of the swing rod, reduces the weight of the swing rod, and reduces the processing cost of the swing rod; at the same time, the cylindrical driving part can reduce the friction when contacting with the first feeding mechanism and the cutter mechanism, and reduce the wear of the driving part, the first feeding mechanism and the cutter mechanism.

[0018] 2. The driving part is rotatably arranged relative to the swing rod, and the driving part cooperating with the first transmission mechanism or the cutting mechanism can rotate, so as to avoid the driving part and the driven component from getting stuck, thereby improving the smoothness of the drive. When the driving part contacts with the first transmission mechanism and the cutting mechanism, the friction force generated by the interaction causes the driving part to rotate, which can further reduce the wear on the contact position, and further reduce the wear on the driving part, the first transmission mechanism and the cutting mechanism.

[0019] 3. The rotation centerline of the driving part is preferably arranged to coincide with its own central axis. The matching contact track between the driving part and the first transmission mechanism is in the shape of an arc and its center always coincides with the rotation centerline of the driving part. The matching contact track between the driving part and the cutting mechanism is in the shape of an arc and its center always coincides with the rotation centerline of the driving part. That is, the distance between each point of the two contact tracks and the rotation centerline of the driving part is always consistent, which can effectively improve the stability of the action of the swing arm driving the first transmission mechanism to achieve feeding and driving the cutting mechanism to achieve shearing through the driving part. In addition, such an arrangement can also reduce the shaking of the driving part when it rotates, thereby further reducing the force between the driving part and the first transmission mechanism and the cutting mechanism, and further reducing the wear of the driving part, the first transmission mechanism and the cutting mechanism.

[0020] 4. The cutter mechanism is reset by driving the driving part in cooperation with the cutter mechanism and the reset spring, thereby realizing the reciprocating motion of the cutter mechanism in cutting materials, simplifying the design of the feeding device, and eliminating the need to set up an additional driving mechanism to increase the volume of the feeding device. In addition, since the spring volume is small and occupies less space, the space required on the frame is saved, thereby further reducing the required size of the frame and further reducing the cost of the feeding device.

[0021] 5. With such arrangement, the swing of the swing arm is transmitted to the cutter mechanism to complete the cutting through reasonable layout. The transmission structure of the cutter mechanism is relatively simple, and correspondingly, its manufacture and assembly are also relatively easy, thereby reducing the production cost of the feeding device.

[0022] 6. The cooperation between the driving part and the first feeding mechanism and the first torsion spring are used to realize the reset of the first feeding mechanism, thereby realizing the reciprocating movement of the first feeding mechanism for feeding. This simplifies the design of the feeding device and eliminates the need to set up an additional driving mechanism that would increase the volume of the feeding device. Moreover, since the torsion spring is small in size and occupies little space, the space required on the frame is saved, further reducing the size of the frame and further lowering the cost of the feeding device.

[0023] 7. By providing the second feeding mechanism and the second driving mechanism, the feeding device can feed out multiple workpieces. Correspondingly, the embroidery machine can embroider more complex patterns with multiple different workpieces, thereby improving the aesthetics of the embroidered products.

[0024] 8. The second driving mechanism includes a second motor. The second motor is arranged below the first motor, and one end of the second connecting rod is sleeved on the motor shaft of the second motor. With this arrangement, the structure of the second driving mechanism and the second feeding mechanism is simpler, which can reduce the production and assembly costs of the feeding device.

[0025] 9. The second driving mechanism includes a second motor and a transmission structure. The second motor is arranged above the first motor, one end of the second connecting rod is hinged to the frame, the transmission structure is arranged between the motor shaft of the second motor and one end of the second connecting rod, and the second motor actuates the second connecting rod through the transmission structure. Since the first driving mechanism drives the first feeding mechanism and the cutting mechanism to operate respectively, and the structure of the second feeding mechanism is simpler than that of the first feeding mechanism and the cutting mechanism, with two feeding mechanisms, through the above arrangement, the distance between the first driving mechanism and the first fork and the cutter does not increase, thus avoiding the increase in cost caused by the increase in the transmission distance of the relatively complex first feeding mechanism and cutting mechanism, and effectively controlling the production and manufacturing cost of the feeding device.

[0026] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiment 1:

[0045] As Figures 1 to 6As shown in the figure, a feeding device for an embroidery machine proposed in an embodiment of the present utility model includes a frame 100, a first feeding mechanism 200, a cutting mechanism 300, and a first driving mechanism 400 provided on the frame 100. The first feeding mechanism 200 includes a first fork 210 that can move back and forth. The cutting mechanism 300 includes a cutter bar 310 rotatably provided at the bottom of the frame 100 and a cutter 320 provided at the front end of the cutter bar 310. The first driving mechanism 400 includes a first motor 410 and a swing rod 420 driven by the first motor 410. The swing rod 420 has a first end actuated by the first motor 410 and a second end away from the first end. The swing rod 420 is provided with a cylindrical driving portion 421 at the second section. The axial direction of the driving portion 421 is substantially perpendicular to the swinging direction of the swing rod 420. The swing rod 420 swinging in the first direction acts on the first feeding mechanism 200 through the driving portion 421 to make the first fork 210 move. The swing rod 420 swinging in the second direction acts on the cutting mechanism 300 through the driving portion 421 to make the cutter bar 310 drive the cutter 320 to rotate. The first direction and the second direction are opposite to each other.

[0046] The first feeding mechanism 200 and the cutting mechanism 300 are respectively driven by the cylindrical driving portion 421, so that there is no need to provide multiple driving portions 421 on the swing rod 420, which simplifies the design and assembly difficulty of the swing rod 420, reduces the weight of the swing rod 420, and reduces the processing cost of the swing rod 420. At the same time, the cylindrical driving portion 421 can reduce the friction force when contacting the first feeding mechanism 200 and the cutting mechanism 300, and reduce the wear of the driving portion 421, the first feeding mechanism 200, and the cutting mechanism 300.

[0047] In this embodiment, the first feeding mechanism 200 conveys the first workpiece for embroidery forward to the working needle position, and the cutting mechanism 300 is used to cut the first workpiece at the working needle position. The workpiece is a plurality of gold flakes or a plurality of bead tubes connected in a strip shape.

[0048] Combined with Figures 1 to 6, in this embodiment, the first feeding mechanism 200 further includes a first connecting rod 220. The first connecting rod 220 includes an upper connecting rod 221, a lower connecting rod 222, and a connecting rod shaft 223. The connecting rod shaft 223 is hinged to the frame 100, and the upper connecting rod 221 and the lower connecting rod 222 are respectively fixedly connected to the connecting rod shaft 223. The lower connecting rod 222 is connected to the first fork 210, and a first torsion spring 230 is provided on the lower connecting rod 222. The first torsion spring 230 is sleeved on the connecting rod shaft 223. One end of the first torsion spring 230 is fixed to the frame 100, and the other end is fixed to the lower connecting rod 222. The upper connecting rod 221 can cooperate with the driving part 421. The swing rod 420 swinging in the first direction drives the first fork 210 to move through the cooperation of the driving part 421 and the upper connecting rod 221 and causes the first torsion spring 230 to deform. When the swing rod 420 swings in the second direction, the action on the upper connecting rod 221 is released, the first torsion spring 230 restores and drives the lower connecting rod 222 to reset, and the upper connecting rod 221 and the first fork 210 reset accordingly, thereby realizing the reciprocating movement of the first fork 210 for feeding.

[0049] Through the cooperation of the driving part 421 and the first feeding mechanism 200 and the first torsion spring 230, the first feeding mechanism 200 is reset, thereby realizing the reciprocating movement of the first feeding mechanism 200 for feeding, simplifying the design of the feeding device, and there is no need to set an additional driving mechanism to cause an increase in the volume of the feeding device. And because the torsion spring is small in volume and occupies less space, the space required on the frame 100 is saved, thereby further reducing the required size of the frame 100 and further reducing the cost of the feeding device.

[0050] Combined Figures 1 to 6 , in this embodiment, the cutting tool mechanism 300 further includes a limit block 311 provided at the rear end of the tool bar 310, a driving rod 330 rotatably hinged to the frame 100, a pull rod 340 with one end connected to the limit block 311 and the other end connected to the driving rod 330, and a return spring 350 for driving the tool bar 310 to rotate and reset. The return spring 350 is connected to the limit block 311, and the connection points of the return spring 350 and the pull rod 340 with the limit block 311 are respectively located on opposite sides of the tool bar 310. The swing rod 420 swinging in the second direction enables the driving part 421 to cooperate with the driving rod 330, so that the driving rod 330 drives the tool bar 310 to rotate through the pull rod 340 and the limit block 311 to complete the cutting of the workpiece. The rotating tool bar 310 causes the force of the return spring 350 to deform. When the swing rod 420 swings in the second direction, the action on the driving rod 330 is released, the return spring 350 restores and drives the limit block 311 and the tool bar 310 to reset, and the pull rod 340 and the driving rod 330 reset accordingly, thereby realizing the cutting and reset of the cutting tool mechanism 300.

[0051] Among them, the driving rod 330 includes a hinged portion 331 hinged to the frame 100, and a driving arm 332 and a driven arm 333 extending from both ends of the hinged portion 331. The driving portion 421 acts on the driving arm 332 to drive the movement of the driven arm 333. One end of the driven arm 333 away from the hinged portion 331 is hinged to the pull rod 340, so that the movement of the driven arm 333 drives the movement of the pull rod 340.

[0052] Through the cooperation of the driving portion 421 and the cutting mechanism 300 and the reset spring 350 driving the cutting mechanism 300 to reset, the reciprocating movement of the cutting mechanism 300 for cutting materials is realized, which simplifies the design of the feeding device and eliminates the need to set up an additional driving mechanism that may increase the volume of the feeding device. Moreover, since the spring has a small volume and occupies little space, the space required on the frame 100 is saved, further reducing the required size of the frame 100 and further reducing the cost of the feeding device.

[0053] In order to further reduce the wear of the driving portion 421, the first feeding mechanism 200, and the cutting mechanism 300, combined with Figure 3 , in this embodiment, the swing rod 420 includes a pin shaft 422. One end of the pin shaft 422 is fixed to the second end of the swing rod 420, and a stop ring 4221 is provided at the other end. The driving portion 421 is separately arranged from the swing rod 420, and the driving portion 421 is rotatably sleeved on the pin shaft 422, and the stop ring 4221 restricts the driving portion 421 from detaching from the swing rod 420.

[0054] The driving portion 421 is rotatably arranged relative to the swing rod 420, and the driving portion 421 cooperating with the first feeding mechanism 200 or the cutting mechanism 300 can rotate, avoiding the situation where the driving portion 421 is easily stuck with the driven component, thereby improving the smoothness of driving. When the driving portion 421 contacts the first feeding mechanism 200 and the cutting mechanism 300, it rotates due to the frictional force generated by the interaction, which can further reduce the wear at the contact position and further reduce the wear of the driving portion 421, the first feeding mechanism 200, and the cutting mechanism 300.

[0055] In this embodiment, the rotation center line of the driving part 421 is preferably coincident with its own central axis. The rotation center line of the driving part 421 is preferably arranged to coincide with its own central axis, the matching contact track between the driving part 421 and the first feeding mechanism 200 is in an arc shape and its center always coincides with the rotation center line of the driving part, and the matching contact track between the driving part 421 and the cutting mechanism 300 is in an arc shape and its center always coincides with the rotation center line of the driving part, that is, the distance between each point of the two contact tracks and the rotation center line of the driving part is always consistent, which can effectively improve the stability of the action of the swing arm driving the first feeding mechanism 200 to achieve feeding and driving the cutting mechanism 300 to achieve shearing through the driving part 421. In addition, such a setting can also reduce the shaking of the driving part 421 when it rotates, thereby further reducing the force between the driving part 421 and the first feeding mechanism 200 and the cutting mechanism 300, and further reducing the wear of the driving part 421, the first feeding mechanism 200 and the cutting mechanism 300.

[0056] In another preferred embodiment, the driving part 421 is preferably a roller or a bearing.

[0057] In some other embodiments, a pin shaft 422 is integrally formed on the driving part 421, and the driving part 421 is rotatably disposed on the second end of the rocker arm 420 through the pin shaft 422. The end of the pin shaft 422 away from the driving part 421 is limited on the rocker arm 420 by a buckle or a retaining spring.

[0058] Embodiment 2:

[0059] Different from the first embodiment, in this embodiment, the driving portion 421 is fixed to the second end of the swing rod 420 .

[0060] Embodiment three:

[0061] Based on embodiments 1 and 2, combined with Figures 1 to 7 In this embodiment, the cutter 320 has a cutting edge 321, and the pull rod 340 and the cutting edge 321 are located on opposite sides of the knife rod 310. The swing arm 420 swinging in the second direction moves the pull rod 340 upward through the cooperation between the driving part 421 and the driving rod 330, so that the pull rod 340 drives the cutter 320 to swing downward through the limit block 311 and the knife rod 310.

[0062] In this embodiment, if Figure 6 As shown, the cutting edge 321 is arranged on the right side of the knife rod 310, the pull rod 340 is arranged on the left side of the knife rod 310, the hinge point of the driving rod 330 is higher than the driving part 421, and the swing of the swing rod 420 in the second direction pushes the driving rod 330 to rotate through the driving part 421, thereby driving the upper end of the pull rod 340 to move upward, and the upward movement of the pull rod 340 located on the left side of the limit block 311 drives the knife rod 310 to rotate so that the cutting edge 321 of the cutter 320 rotates to complete the cutting.

[0063] With such a setting, through a reasonable layout, the swing of the swing rod 420 is transmitted to the cutting tool mechanism 200 to complete the material cutting. The transmission structure of the cutting tool mechanism 200 is relatively simple. Correspondingly, its manufacturing and assembly are also relatively easy, thereby reducing the production cost of the feeding device.

[0064] Embodiment Four:

[0065] Different from Embodiment Three, in this embodiment, the cutting tool 320 has a cutting edge 321. The pull rod 340 and the cutting edge 321 are located on the same side of the tool bar 310. The swing rod 420 swinging in the second direction drives the pull rod 340 to move downward through the cooperation of the driving part 421 and the driving rod 330, so that the pull rod 340 drives the cutting tool 320 to swing downward through the limiting block 311 and the tool bar 310.

[0066] In this embodiment, both the cutting edge 321 and the pull rod 340 are arranged on the right side of the tool bar 310. The hinge point of the driving rod 330 is lower than the driving part 421. The swing of the swing rod 420 in the second direction drives the driving rod 330 to rotate through the driving part 421, thereby driving the upper end of the pull rod 340 to move downward. The downward movement of the pull rod 340 located on the right side of the limiting block 311 drives the tool bar 310 to rotate so that the cutting edge 321 of the cutting tool 320 rotates to complete the material cutting.

[0067] With such a setting, through a reasonable layout, the swing of the swing rod 420 is transmitted to the cutting tool mechanism 200 to complete the material cutting. The transmission structure of the cutting tool mechanism 200 is relatively simple. Correspondingly, its manufacturing and assembly are also relatively easy, thereby reducing the production cost of the feeding device.

[0068] Embodiment Five:

[0069] Based on Embodiments One to Four, combined with Figures 1 to 7 , in this embodiment, the embroidery machine feeding device further includes a second driving mechanism 600 and a second feeding mechanism 500. The second feeding mechanism 500 includes a second connecting rod 510 and a second fork 520. One end of the second connecting rod 510 is actuated by the second driving mechanism 600, and the other end of the second connecting rod 510 is connected to the second fork 520. The second connecting rod 510 actuated by the second driving mechanism 600 drives the second fork 520 to move. The second fork 520 is used to convey the second material for embroidery forward to the working needle position, wherein the heights of the second material and the first material are different.

[0070] A second torsion spring 530 is provided at the connection between the second connecting rod 510 and the second fork 520, one end of the second torsion spring 530 is fixed to the frame 100, and the other end is fixed to the second connecting rod 510. The second driving mechanism 600 drives the second connecting rod 510 to move in one direction to drive the second fork 520 to move, and the movement of the second fork 520 causes the second torsion spring 530 to deform. The second driving mechanism 600 releases the action on the second connecting rod 510, and the second torsion spring 530 recovers to drive the second connecting rod 510 to reset, and the second fork 520 is reset accordingly, thereby realizing the reciprocating motion of the second fork 520.

[0071] In this embodiment, if Figure 7 As shown, the cutting edge 321 includes a first cutting edge 3211 and a second cutting edge 3212. The first cutting edge 3211 is used to cut the first material, and the second cutting edge 3212 is used to cut the second material. The first feeding mechanism 200 and the second feeding mechanism 500 can feed materials at the same time, so that the cutting edge 321 cuts the first material and the second material at the same time. The first feeding mechanism 200 and the second feeding mechanism 500 can also feed materials separately, so that the cutting edge 321 cuts the first material or the second material.

[0072] In some other embodiments, a cutting edge 321 may be used to cut the first material and the second material, and the movement range of the cutter 320 may be increased by increasing the rotation angle of the cutter 320 rod, so that the cutting edge 321 can cut the first material and the second material.

[0073] By providing the second feeding mechanism and the second driving mechanism 600, the feeding device can feed a plurality of materials. Accordingly, the embroidery machine can embroider more complicated patterns with a variety of different materials, thereby improving the aesthetics of the embroidery products.

[0074] Preferably, in this embodiment, the second driving mechanism 600 includes a second motor, which is disposed below the first motor 410 , and one end of the second connecting rod 510 is sleeved on the motor shaft of the second motor.

[0075] With such arrangement, the structures of the second driving mechanism 600 and the second feeding mechanism 500 are simpler, which can reduce the production and assembly costs of the feeding device.

[0076] Embodiment six:

[0077] Different from the fifth embodiment, in this embodiment, the second driving mechanism 600 includes a second motor and a transmission structure. The second motor is arranged above the first motor 410, one end of the second connecting rod 510 is hinged to the frame 100, and the transmission structure is arranged between the motor shaft of the second motor and one end of the second connecting rod 510. The second motor actuates the second connecting rod 510 through the transmission structure.

[0078] Among them, the transmission structure can be a structure similar to the first connecting rod 220 in the first feeding mechanism 200.

[0079] Since the first driving mechanism 400 drives the first feeding mechanism 200 and the cutting tool mechanism 300 to operate respectively, and the structure of the second feeding mechanism 500 is simpler than that of the first feeding mechanism 200 and the cutting tool mechanism 300, with two feeding mechanisms provided, through the above settings, the distance between the first driving mechanism 400 and the first fork 210 and the cutting tool 320 does not need to be increased, thus avoiding the increase in cost caused by the increase in the transmission distance of the relatively complex first feeding mechanism 200 and the cutting tool mechanism 300, and effectively controlling the production and manufacturing cost of the feeding device.

[0080] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
