Aiming at the defects of the existing independent carving holes and carving holes of an additional device, as shown in fig. 1 to 7, the invention provides an independent carving hole device which is arranged on an embroidery machine head, the embroidery machine head comprises a machine head body 4 and a needle bar frame 5 arranged in front of the machine head body, wherein the machine head body 4 comprises a machine head shell, a main shaft, a needle bar driving component 2, a needle bar driver and the like which are arranged on the machine head shell, a row of needle bars 51 formed by arranging a plurality of needle bars are arranged on the needle bar frame 5 along the left-right direction, a color changing slide rail is arranged between the needle bar frame 5 and the machine head shell, and the needle bar frame 5 is driven by the color changing driver to slide left and right along the color changing slide rail for color changing. The needle bar driving component 2 is used for driving the needle bar driver, and then the needle bar driver drives the needle bar 51 on the needle bar frame to embroider, and the needle bar driving clutch is required to act before and after color changing. The conventional structure and the working principle of the embroidery machine can refer to the prior art, and are not described in detail herein. In order to realize the individual engraving without adding a separate engraving motor, the individual engraving device of the invention is driven by a needle bar driving assembly 2, said needle bar driving assembly 2 being provided with an up-and-down movable engraving driving member.
In addition, the individual engraving device is further provided with:
the hole carving driver 1 comprises a guide shaft 11 and a driving block 12, wherein the driving block 12 is provided with a guide hole which is in up-and-down sliding fit with the guide shaft 11;
the engraving hole clutch 3 comprises a clutch component, and the connection and the separation between the engraving hole driving piece and the driving block 12 are realized through the clutch component.
During the carving, the clutch component forms a transmission connection between the carving driving piece and the driving block 12, so that the driving block 12 can be driven by the carving driving piece to move up and down along the guide shaft 11. When the carving hole is changed into the ordinary embroidery, the clutch component performs clutch action, so that the carving hole driving piece and the driving block 12 are separated and are not in transmission connection. When the common embroidery is converted into the carving hole, the clutch component performs clutch action, and the clutch component enables the carving hole driving piece and the driving block 12 to form transmission connection.
It can be understood that the form of the driving block 12 sliding up and down with the guide shaft 11 through the guide hole includes both the circular shaft hole fit and the shaft hole fit with other shapes, and even the similar various sliding guide forms.
With respect to the row of needle bars 51 of the needle bar frame 5, one needle bar 51 is provided with the engraving needle 511, the other needle bars 51 are provided with the embroidery needle 512, the needle bar 51 provided with the engraving needle 511 is positioned at a first needle position of the needle bar frame 5, which is shown as the first needle position on the right side in fig. 2, the needle bar 51 provided with the engraving needle 511 is driven by the driving block 12 to perform engraving, and the needle bar provided with the embroidery needle 512 is driven by the needle bar driver to perform general embroidery. When the common embroidery and the carving hole are mutually switched, if the common embroidery is switched to the carving hole, the needle rod driving clutch firstly acts, then the carving hole clutch secondly acts, finally the needle rod driving component 2 can drive the carving hole driver 1 to carve the hole, but the needle rod driver cannot be driven to do the common embroidery, if the carving hole is switched to the common embroidery, the carving hole clutch firstly acts, then the needle rod driving clutch secondly acts, and finally the needle rod driving component 2 can drive the needle rod driver to do the common embroidery, but the carving hole driver 1 is not driven to do the carving hole.
Here, the hole-carving needle 511 is detachably mounted on the needle bar corresponding to the first needle position, and can be fixed by matching screws with mounting holes, so that the hole-carving needle 511 on the needle bar of the first needle position can be detached and replaced by the embroidery machine needle 512, and also can be used for ordinary embroidery.
Referring to the structure of the needle bar drive assembly 2 in the prior art, the needle bar drive assembly 2 includes a three-eye link 21, a small link 22, and a link pin 23 connecting a front end eye of the three-eye link and a rear end eye of the small link. The machine head shell transversely penetrates through a main shaft of the embroidery machine, the main shaft of the embroidery machine is connected with a needle rod driving cam in the machine head shell, and the needle rod driving cam drives the three-hole connecting rod 21 through a large connecting rod. Other structures and working principles of the needle bar driving assembly can be referred to in the prior art, and are not described in detail herein.
The invention adds a carving hole driving component in order to realize that the needle bar driving component 2 can also drive the driving block 12 of the carving hole driver.
In one embodiment, the engraved drive member is an engraved drive wheel 24 coupled to a link pin 23. The engraved driving wheel may employ rollers, bearings, and the like as rolling elements. Therefore, when the connecting rod pin 23 moves up and down, the engraving driving wheel 24 can be driven to move up and down.
Due to the design of the engraving clutch 3, the connection and disconnection between the engraving drive member and the drive block 12 can be realized. The carving hole driving wheel 24 obtains power from the main shaft through the three-hole connecting rod 21 and drives the needle rod (the head of the needle rod is provided with a carving hole knife needle 511) on the first needle position, thereby achieving the effect of carving holes (cutting holes) on the cloth. Therefore, a single hole carving motor is not needed to be added, and the cost is reduced. When the ordinary embroidery and the carving hole embroidery are switched, the needle rod driving clutch and the carving hole clutch are matched only in action, the ordinary embroidery and the carving hole embroidery can be switched at will, and the machine does not need to be stopped for switching. When a certain batch of products are touched in the actual use process and the carving pattern is not needed, the carving knife needle 511 is only needed to be detached and the embroidery machine needle 512 is replaced, the common embroidery can be carried out, the applicability is wide, and the use cost of customers is reduced.
In addition, the carving hole driver 1 further comprises a carving hole driving seat 10, the carving hole driving seat 10 is installed on the machine head shell, and the guide shaft 11 is vertically installed on the carving hole driving seat 10. The guide shaft 11 is provided with a return spring 13 below the driving block 12 for returning the driving block 12 upwards after the engraving is completed. The upper part of the driving block 12 is connected with a buffer block 14, and when the driving block 12 is upwards contacted with the carving hole driving seat 10, the buffer block 14 can realize buffer, so that the impact is reduced.
Example one
As shown in fig. 1 to 6, the carving hole clutch in the present embodiment includes a clutch block 31 horizontally rotatably connected to the driving block 12, and the clutch block and the driving block may be hinged by a vertical pin. Therefore, the clutch block 31 horizontally rotates to realize transmission connection or separation with the carving hole driving piece, when carving is carried out, the carving hole driving piece is in transmission connection with the clutch block 31, and when carving is not carried out, the clutch block 31 is separated from the carving hole driving piece.
Specifically, the clutch block 31 is provided with a driving groove 312, the clutch block is engaged and disengaged by the connection and the disconnection between the carving hole driving member and the driving groove 312, and the carving hole driving member is movably embedded into the driving groove 312 when carving is performed. The engraved hole stops when the needle bar drive assembly 2 drives the needle bar to which the embroidery machine needle corresponds, and the engraved hole drive member does not act on the drive block 12 although it still remains moving because it is disengaged from the drive slot 312.
Preferably, the driving groove 312 is U-shaped, the front end is a closed U-shaped bottom wall, and the two side walls of the U-shape are parallel up and down. The engraved drive wheel 24 may roll back and forth within the drive slot 312. A torsion spring 311 is arranged between the clutch block 31 and the driving block 12, the carving hole driving member and the driving groove 312 have a separation movement trend through the torsion spring 311, and only when the carving hole is formed, the clutch block 31 is driven by external force to overcome the acting force of the torsion spring 311 to rotate and enter the driving groove 312. When the carving is not performed, the external force applied to the clutch piece 31 disappears, and the torsion spring 311 can reset the clutch piece 31 to be separated from the driving groove 312. Of course, it can be understood that it is not excluded that the torsion spring is not provided for resetting, but the clutch block is driven by external force to swing back and forth to perform the clutch action.
Furthermore, in order to drive the clutch block 31 to rotate, the carving clutch 3 further comprises a swinging shaft 33 and a swinging block 32 mounted on the swinging shaft 33, wherein the swinging shaft 33 is rotatably mounted on a swinging shaft seat 34. The swing block 32 is located on the back side of the clutch block 31 where the driving groove 312 is provided, so that the swing block 32 can be driven by the swing shaft 33 to swing, and the clutch block 31 is driven to rotate by the swing block 32.
In actual use, the torsion spring may fail, and even if the situation is converted into normal embroidery, the carving is performed while the normal embroidery is performed. This is of course not allowed and therefore adds a safety. In order to avoid that the clutch block 31 cannot be reset when the torsion spring 311 fails, a return shifting piece 331 is further fixed on the swinging shaft 33, and specifically, the return shifting piece 331 can be fixed in a hoop manner. When the swing shaft 33 is returned, if the torsion spring is not acted in time, the return shifting piece 331 will shift the clutch block 31, so as to reset the clutch block 31. From the axial view of the oscillating shaft 33, the oscillating block 32 and the return finger 331 are angularly spaced in the circumferential direction of the oscillating shaft 33 so as to be located on both sides of the clutch block 31, respectively, with different directions of the acting force on the clutch block 31, and the position of the return finger 331 ensures that the torsion spring is acted first.
Because the space in the head shell is narrow, and the difficulty of increasing a power source to drive the oscillating shaft 33 in the head shell is high, the carving clutch 3 further comprises a pull rod 37 arranged outside the head shell, and a connecting rod assembly is arranged between the pull rod 37 and the oscillating shaft 33, and because the pull rod 37 is horizontally pulled left and right and is vertical to the axial direction of the oscillating shaft 33, the transmission direction is changed through the linear movement of the pull rod 37 and the connecting rod assembly to drive the oscillating shaft 33 to rotate.
The connecting rod assembly comprises a first connecting rod 36 and a second connecting rod 35, the first connecting rod 36 is provided with a vertical portion 361 and a horizontal extending portion 362 extending horizontally from the lower end of the vertical portion to the side face, the vertical portion 361 can be fixed with the pull rod 37 in a hoop mode, the horizontal extending portion 362 is hinged with the rear end of the second connecting rod 35, and the front end of the second connecting rod 35 is fixed with the swinging shaft 33. Thus, the horizontal linear movement of the pull rod 37 is converted into horizontal rotation of the swing shaft 33 by the above-described design. It will of course be understood that the substitution of other transmission means between the tie rod 37 and the oscillating shaft 33 is not excluded.
The pull rod 37 is mounted on a handpiece shell, a pull rod supporting seat 38 for supporting the pull rod 37 is fixed on the handpiece shell, and the pull rod 37 can be driven by a pull rod motor.
Example two
In this embodiment, the engraved hole clutch is different from the first embodiment.
The carving hole clutch comprises a carving hole driving pin shaft 303 and a carving hole driving connecting rod 301 which is rotatably connected to the carving hole driving pin shaft 303, the carving hole driving pin shaft 303 extends left and right in the horizontal direction, and the carving hole driving connecting rod 301 is in transmission connection or separation with the carving hole driving piece and the driving block 12 through the horizontal sliding of the carving hole driving connecting rod 301 along the carving hole driving pin shaft 303. When the carving hole is performed, the carving hole driving connecting rod 301 is in transmission connection with the carving hole driving piece and the driving block 12, the carving hole driving connecting rod 301 is driven by the carving hole driving piece to swing up and down, and the driving block 12 is driven to slide up and down along the guide shaft 11 by the up-and-down swing of the carving hole driving connecting rod 301. When the needle bar driving assembly 2 drives the needle bar corresponding to the embroidery machine needle, the carving hole is stopped, and the carving hole driving link 301 is staggered with the carving hole driving member and is not in transmission connection with the driving block 12, so that the carving hole driving member still keeps moving but does not act on the driving block 12.
Further, the carving hole driving link 301 is connected to a driving swing link 302, and a driving inclined surface 3021 matched with the carving hole driving wheel 24 above is disposed on the back side of the driving swing link 302. When the carving driving wheel 24 moves downwards, the carving driving wheel presses on the driving inclined plane 3021 of the driving swing rod 302, and drives the driving swing rod 302 to swing downwards. Furthermore, the front end of the driving bevel 3021 is provided with a limiting protrusion 3022, so that the carving driving wheel 24 is always positioned at the rear side of the limiting protrusion 3022 even if the carving driving wheel 24 presses the driving swing link 302 downwards to the maximum limit position.
In order to realize the transmission connection between the driving block 12 and the carving hole driving connecting rod 301, the driving block 12 is provided with a driving groove 121 which extends transversely and can be penetrated transversely left and right, the carving hole driving connecting rod 301 is connected with a clutch driving wheel 305, the clutch driving wheel 305 is movably embedded into the driving groove 121, and the carving hole driving connecting rod 301 drives the driving block 12 to move up and down through the clutch driving wheel 305 when swinging up and down. Since the clutch driving wheel 305 is slidable in the driving groove 121 in the left-right direction, the clutch driving wheel 305 moves in the left-right direction when the engraved hole driving link 301 performs a clutch operation of moving in the left-right direction, but always moves in the driving groove 121 without being separated from each other. The clutched drive wheel 305 is secured to the engraved drive link 301 by a nut 306. The clutch drive wheel 305 may employ rollers, bearings, or similar rolling elements.
The clutch driving wheel 305 and the driving recess 121 are not separated during the clutch process, and the eyelet driving wheel 24 may move up and down during normal embroidery even though the eyelet is not driven, so that the driving bevel 3021 may be shifted from the eyelet driving wheel 24 in the left-right direction when the eyelet is not driven after the clutch operation, and thus the driving bevel 3021 may not be pressed against the driving bevel 3021 when the eyelet driving wheel 24 moves down. The carving hole clutch has the clutch function required by design.
The driving recess 121 is formed in the rear protrusion of the driving block 12 at the rear side thereof, and the driving swing lever 302 is offset from the rear protrusion in the left-right direction so that the driving swing lever 302 does not interfere with the rear protrusion when swinging up and down. The clutched drive wheel 305 and the drive groove 121 are not always disengaged during clutching. Since the driving swing link 302 and the clutch driving wheel 305 are both connected to the carving hole driving link 301, the driving swing link 302 and the clutch driving wheel 305 also need to be staggered, here, a front side step 3011 is arranged on the front side of the carving hole driving link 301, the clutch driving wheel 305 is located at the front side step 3011, the driving swing link 302 is fixed on the front side of the carving hole driving link 301 through a screw, and therefore, the driving swing link 302 and the clutch driving wheel 305 are completely staggered left and right.
In addition, the carving hole driving link 301 is connected with a pin bushing 304, and is slidably connected with the carving hole driving pin 303 through the pin bushing 304.
In order to realize the clutch action, the carving hole driving connecting rod 301 horizontally slides left and right along the carving hole driving pin shaft 303. The carving hole clutch further comprises a clutch driving body 307 capable of moving linearly left and right, the clutch driving body 307 is provided with a clutch groove 3071, when the clutch driving body 307 moves left and right, the carving hole driving connecting rod 301 is driven to move left and right through the clutch groove 3071, and the clutch groove 3071 is provided with a space for accommodating the carving hole driving connecting rod 301 to swing up and down. In this embodiment, the clutch groove 3071 is a U-shaped groove, the rear extension 3012 extending into the clutch groove 3071 is disposed on the rear side of the carved hole driving pin shaft 303 of the carved hole driving link 301, and the rear extension 3012 and the front portion of the carved hole driving link 301 form an included angle of about 90 degrees.
Similar to the first embodiment, the engraved clutch in this embodiment also has a pull rod 37, and the pull rod 37 and the clutch driving body 307 can be fixedly connected by a hoop.
In summary, it can be known from the above description of the first and second embodiments that the structure and form of the carving hole clutch can be changed as long as the connection and disconnection between the carving hole driving member and the driving block are realized by the clutch component.
