Description

Technical Field

[0001] The utility model relates to the technical field of computer embroidery machines, in particular to a high-efficiency multi-color rope embroidery device. Background Art

[0002] The multi-color cord embroidery device is a device that is often used in the cord embroidery process of embroidery machines. It can automatically switch the color of the cord during production according to the program setting to achieve continuous automated production. However, in the automated production of multi-color cord embroidery, the embroidery machine often interrupts production and issues warning signals due to various reasons. The reasons are roughly divided into two categories: one is that the cord transportation or color change is not smooth, resulting in empty needle piercing or missing piercing, or the embroidery needle breaks due to the position deviation of the cord and the embroidery needle; the other is that when the fabric is thick or the cord is thick, the bottom of the cord guide (and the cord on it) is against the fabric, and the sensing device sends a feedback signal to instruct the motor to stop driving. Therefore, in the production of multi-color cord embroidery, an embroidery machine often needs to be equipped with at least one professional technician to guard the machine to solve various temporary shutdown and alarm problems in production. The machine output efficiency is not high and the workload of the technician is heavy. Utility Model Content

[0027] When changing colors, the translation motor 48 drives the nozzle guide frame 47 to translate the specific nozzle guide shaft 45 to the side of the driving block 44 and is clamped by its bayonet 4, the driving motor 41 drives the first connecting rod 42 to rotate, the first connecting rod 42 drives the second connecting rod 43 to swing, pulls the driving block 44 to slide on the rotating shaft 46, pushes the nozzle guide shaft 45 to slide on the nozzle guide frame 47 through the bayonet 4, and sends the nozzle guide 60 with a specific embroidery rope to the bottom of an embroidery needle 50. The color changing principle and color changing process of the multi-color rope embroidery device belong to the prior art, and its detailed structure is not repeated here.

[0028] like Figure 3As shown, the rope feeding mechanism 70 is mounted on the driving seat 49 and is located above the driving mechanism 40, including a base 71 arranged on the driving seat 49, and a plurality of groups of linearly arranged feeding roller groups 72 are arranged on the base 71, each group of feeding roller groups 72 includes a driving roller 2 and a driven roller 3 arranged in parallel, and an embroidery rope can pass between the two; a driving assembly 73 is provided on the base 71, and each driving assembly 73 can be connected to an active roller 2 and can drive it to rotate, so as to drive an embroidery rope thereon to move forward.

[0029] In this embodiment, if Figure 3 As shown, the driving assembly 73 includes a first driving device 5 arranged on a base 71 and a lead screw 6 transmission-connected thereto, the lead screw 6 extends along the arrangement direction of a plurality of feed roller groups 72, and a nut seat 7 transmission-connected to the lead screw 6, and the nut seat 7 can translate along the lead screw 6 to move to the side of an active roller 2 under the drive of the first driving device 5; a second driving device 8 and a transmission wheel 9 transmission-connected thereto are arranged on the nut seat 7, and the transmission wheel 9 can rotate under the drive of the second driving device 8 and drive the active roller 2 to rotate; a sensor 90 is arranged on the side of each feed roller group 72, and each sensor 90 is electrically connected to the second driving device 8.

[0030] During operation, each embroidery rope passes through the middle of the active roller 2 and the driven roller 3 in a feed roller group 72; when a specific embroidery rope is needed, the first drive device 5 drives the lead screw 6 to rotate and drives the nut seat 7 to translate toward the embroidery rope (feed roller group 72), and the sensor 90 next to the feed roller group 72 senses that it has moved into place and instructs the second drive device 8 to drive the transmission wheel 9 to rotate. At this time, the transmission wheel 9 is just in contact with the top of the active roller 2 and drives it to rotate, thereby driving the embroidery rope against it to move forward, completing the rope feeding action, ensuring that the embroidery rope can always move smoothly, avoiding or reducing the phenomenon of missed stitches or broken stitches caused by the embroidery rope being stuck.

[0031] In this embodiment, if Figure 3 As shown, a mounting frame is set up on one side of the base 71, and each active roller 2 and driven roller 3 are set up therein and can rotate relative to it. One end of each active roller 2 extends to the outside of the mounting frame and is matched to the lower end of the transmission wheel 9. The mounting frame is provided with adjustment grooves on both sides of each driven roller 3, and both ends of each driven roller 3 are set up in two adjustment grooves so that the distance between it and the active roller can be adjusted according to the thickness of the embroidery rope used to ensure smooth thread feeding.

[0032] In this embodiment, if Figure 4As shown, the buffer assembly 80 is arranged on the driving card block 44, including a longitudinally extending guide rod 81, a spring 82 and a connecting block 83. The guide rod 81 is mounted on the end of the driving card block 44 away from the bayonet 4, and the spring 82 and the connecting block 83 are sequentially sleeved on the guide rod 81. The connecting block 83 is arranged at the end away from the guide nozzle 60 and its two ends respectively abut against the spring 82 and the driving card block 44, and one end of the connecting block 83 is hinged to the second connecting rod 43; the driving card block 44 is hinged on a mounting shaft 46, and its two ends are both U-shaped structures, one U-shaped end forms the bayonet 4, and the other U-shaped end is provided with a guide rod 81.

[0033] During the color change process, when the embroidery cloth is too thick or the embroidery rope is too thick, the guide nozzle 60 may be blocked when it is moved into position, causing the drive motor 41 to be unable to continue to pull the drive block 44 downward, and the drive motor 41 may be stuck and send a warning signal to instruct the embroidery machine to stop. In the present invention, when the guide nozzle 60 (guide nozzle shaft 45) is blocked, the drive motor 41 can still drive the connecting block 83 to buffer and move a certain distance. Within a certain range, the drive motor 41 will not be stuck and will not send a command signal to stop the machine operation, ensuring that the embroidery machine can continue to embroider embroidery ropes within a certain range of thickness on embroidery cloth within a certain range, reducing the number of machine shutdown errors, and improving the production efficiency of the embroidery machine. In application, according to actual conditions, a spring 82 with appropriate elasticity and a guide rod 81 of appropriate length can be selected to ensure that the applicable materials for continuous production of the embroidery machine are expanded without damaging the embroidery needle 50.

[0034] like Figure 5 As shown, each guide nozzle 60 is an integrated L-shaped structure, including an intersecting first arm 61 and a second arm 62, the first arm 61 matches the guide nozzle shaft 45 and is detachably fixed thereto, and the two ends of the second arm 62 are formed with rope holes 11 adapted to the embroidery rope, and a rope passage 12 is formed between the two rope holes 11, and an embroidery hole 13 that can pass an embroidery rope and an embroidery needle 50 is provided on the side of each rope hole 11.

[0035] The utility model sets the guide nozzle 60 as an integrally formed structure, replacing the conventional structure composed of multiple accessories, which can further effectively reduce the accumulated errors caused by manufacturing and assembly, thereby achieving the purpose of further reducing the swing of the guide nozzle, ensuring the position accuracy of the embroidery needle 50, avoiding or reducing the probability of missed stitches and broken stitches, and improving the embroidery quality.

[0036] like Figure 6 As shown, the rope cutting mechanism 30 includes a mounting plate 31 which is tilted above the embroidery cloth, on which a lifting drive device 32 and a rope cutting drive device 33 which are transmission-connected thereto are provided, and the rope cutting drive device 33 is transmission-connected to scissors 34, which are tilted and whose ends are parallel to the embroidery cloth.

[0037] In this embodiment, the lifting drive device 32 and the rope cutting drive device 33 are both linear cylinders. The scissors 34 include a fixed plate arranged on the mounting plate 31 and a driving plate transmission-connected to the rope cutting drive device 33. The fixed plate and the driving plate are both bent structures and are arranged opposite to each other. The rope cutting drive device 33 drives the driving plate to approach or move away from the fixed plate to achieve cutting or moving away from the embroidery rope.

[0038] The utility model tilts the scissors 34 so that an angle a is formed between the scissors and the mounting plate 31, so that the bottom of the scissors can be parallel to the embroidery cloth, avoiding the tip of the knife from piercing the embroidery cloth and ensuring the quality of the embroidery. In this embodiment, the angle a between the scissors and the mounting plate is about 132°; in the application, a can be set to a suitable angle according to the position of the rope cutting mechanism 30 on the frame and its actual relative position with the parallel mechanism 20.

[0039] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
