Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Please see Figure 1-9 This embodiment provides the following technical solution: an automatic threading device for seven-star floating threads, including a processing table 10.

[0036] A wire feeding device 40 is provided on the processing table 10. The wire feeding device 40 includes a wire feeding frame 41 and a wire feeding frame 43. The wire feeding frame 41 is fixedly connected to the processing table 10. A wire feeding reel 42 is rotatably connected to the wire feeding frame 41. The wire feeding frame 43 is slidably connected to the wire feeding frame 41 and moves along the X-axis. A wire clamp 44 is fixedly connected to the wire feeding frame 43. A pressure wheel 45 is rotatably connected to the left side of the wire clamp 44. A wire feeding tube 46 is fixedly connected to the right side of the wire clamp 44.

[0037] In some embodiments, the line feeder 42 is driven by a geared motor on the line feeder 41 to perform line feeding operations, while the line feeder 43 is slidably connected to the line feeder 41 via a slide cylinder. Under the driving action of the slide cylinder, the line feeder 43 can drive the line clamp 44, the pressure roller 45, and the line feed tube 46 to move along the X-axis direction of the line feeder 41. At the same time, the line feeder 42 rotates to perform line feeding operations. Under the clamping action of the line clamp 44 on the fishing line, the fishing line can be pulled to perform line feeding operations.

[0038] like Figure 3 and Figure 5As shown, it also includes a wire guide mechanism 48, which includes a wire guide frame 48a, a first wire guide wheel 48b, and a second wire guide wheel 48c. The wire guide frame 48a is fixedly connected to the line feed frame 41. An axle is fixedly connected to the top of the wire guide frame 48a. Two first wire guide wheels 48b are rotatably connected to the axle and are distributed along the axial direction of the axle. The second wire guide wheel 48c is slidably connected to the wire guide frame 48a and located below the first wire guide wheels 48b. In some embodiments, one end of the fishing line passes sequentially around the left side of the rear first wire guide wheel 48b, the right side of the second wire guide wheel 48c, the left side of the front winding wheel, the lower edge of the pressure wheel 45, and the line clamp 44 until the fishing line is completely passed through the line feed tube 46. Under the action of the wire guide mechanism 48, the fishing line can always be kept taut during the threading process, avoiding the fishing line from getting tangled or loose, which would prevent the threading from being completed.

[0039] A base plate 48d is fixedly connected to the bottom of the line feeder 48a. An adjusting block 48f is slidably connected above the base plate 48d via a guide rod 48e. The second guide wheel 48c is rotatably connected to the adjusting block 48f. In some embodiments, two guide rods 48e are provided. The adjusting block 48f is provided with a slot for the guide rods 48e to pass through. During the line feeding process of the line feeder 43, the tension of the fishing line will drive the second guide wheel 48c and the adjusting frame to slide upward along the guide rod 48e. After the line feeder 43 resets, the adjusting block 48f resets. During the movement of the adjusting block 48f driven by the fishing line, it has a buffering effect on the fishing line. Excessive tension during the line feeding process can damage the fishing line.

[0040] like Figure 3 As shown, it also includes a clamping mechanism, which is set on the threading table 20 and corresponding to the line feeding tube 46. The clamping mechanism includes a clamping frame 49 and a pneumatic gripper 410. The clamping frame 49 is fixedly connected to the threading table 20, and the pneumatic gripper 410 is fixedly connected to the top of the clamping frame 49 for clamping and fixing the fishing line after it has been fed. With the pneumatic gripper 410, after the line feeding tube 46 drives the fishing line to a suitable position along the X-axis, the end of the fishing line can be clamped and fixed, so that the line feeding frame 43 can drive the line clamp 44 and the line feeding tube 46 to reset.

[0041] like Figure 3 and Figure 4 As shown, it also includes a pneumatic scissors 411, which is fixedly connected to the line feeder 41 and is used to cut the fishing line after it has been fed. In some embodiments, the pneumatic scissors 411 is located on the right side of the line feeder 40. The pneumatic scissors 411 can be used to cut the fishing line.

[0042] In some embodiments, the line feeding device 40 can complete the fixed-length line feeding operation of the fishing line through the steps of releasing, feeding, clamping, and cutting the line, thereby replacing the manual line feeding method. This facilitates threading the fishing line onto the float and improves the line feeding efficiency.

[0043] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a threading table 20 is fixedly connected above the processing table 10. A threading device 30 is provided on the threading table 20 and is located on the right side of the thread supply device 40. The threading device 30 includes a bean holder 31, a pressing seat 33, a needle holder 32, and a hook needle 34. The bean holder 31 is slidably connected to the threading table 20 and moves along the X-axis direction to transfer the bean to the feeding area or the threading area. In some embodiments, the bean holder 31 is located in front of the thread feeding tube 46. The bean holder 31 is connected to the threading table 20 through a sliding cylinder. Under the driving action of the sliding cylinder, the bean holder 31 reciprocates along the X-axis direction on the threading table 20, thereby moving the bean to be threaded into the threading area, and then resetting the bean after threading.

[0044] In some embodiments, after the float bean is pressed and fixed by the threading device 30, the hook 34 passes through the line groove on the float bean and pulls the fishing line, thereby passing the fishing line through the float bean and completing the threading operation of the float bean. This replaces the traditional manual threading method, reduces labor costs, and improves threading efficiency and quality.

[0045] like Figure 7 and Figure 8 As shown, the needle holder 32 is slidably connected to the threading platform 20 and moves along the Y-axis. A hook 34 is fixedly connected to the needle holder 32, which is used to pass the hook 34 through the float bean and pull the fishing line through the line groove inside the float bean. In some embodiments, the needle holder 32 is connected to the threading platform 20 through a lead screw transmission platform. Under the action of the lead screw transmission platform, the needle holder 32 drives the hook 34 to move along the Y-axis of the threading platform 20, and improves the accuracy of the movement of the hook 34. This allows the hook 34 to pass through the line groove on the float bean and pull the fishing line behind the float bean through the float bean, thus completing the threading operation of the float bean fishing line.

[0046] like Figure 7 and Figure 8As shown, the pressing seat 33 is slidably connected above the bean holder 31 and moves along the Z-axis direction to press the bean onto the bean holder 31. In some embodiments, a stand is fixedly connected to the left side of the needle holder 32 on the threading platform 20, and a telescopic cylinder is fixedly connected above the stand. The piston end of the telescopic cylinder is fixedly connected to the pressing seat 33. Under the action of the telescopic cylinder, the pressing seat 33 moves along the Z-axis direction of the stand, which can press the bean onto the bean holder 31 to press and fix the bean on the bean holder 31, or the pressing seat 33 can be moved away from the bean holder 31.

[0047] The rear side of the pressing seat 33 is slidably connected to the pressing block 35, which moves along the Z-axis direction to press the fishing line onto the hook groove on the hook 34. In some embodiments, the pressing block 35 is positioned above the fishing line, and the stand is also equipped with a telescopic cylinder for driving the pressing block 35 to move along the Z-axis direction of the stand. Under the action of the telescopic cylinder, after the pressing seat 33 is pressed onto the float bean seat 31, the fishing line can be pressed onto the hook groove on the hook 34, making it easier for the hook 34 to hook the fishing line and facilitating the pulling of the fishing line for threading.

[0048] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, a feeding device 50 is installed on the processing table 10. The feeding device 50 is located behind the threading equipment. The feeding device 50 includes a feeding rack 51, a hopper 52, a sweeping brush 53, and a material tray 54. The feeding rack 51 is fixedly connected to the processing table 10. The hopper 52 is fixedly connected to the feeding rack 51. The sweeping brush 53 is rotatably connected inside the hopper 52. A discharge trough is provided at the bottom of the hopper 52. The material tray 54 is rotatably connected inside the discharge trough. The material tray 54 is provided with circumferentially distributed bean-floating troughs. In this embodiment, a geared motor is fixedly connected to the hopper 52, and a rotating shaft is fixedly connected to the output shaft of the geared motor. The bottom of the rotating shaft extends to the bottom of the hopper 52 and is fixedly connected to a sweeping brush 53. A geared motor is also fixedly connected to the bottom of the feeding rack 51. The output shaft of the geared motor passes through the feeding rack 51 and is fixedly connected to the material tray 54. During the continuous rotation of the material tray 54 and the sweeping brush 53, the floating beans can enter the floating bean trough on the material tray 54 one by one, achieving the effect of material distribution.

[0049] like Figure 3 , Figure 8 and Figure 9As shown, a gripping device 60 is provided on the threading table 20. The gripping device 60 is located on the right side of the feeding device 50. The gripping device 60 includes a movable frame 61 and a gripping frame 62. The movable frame 61 is slidably connected to the threading table 20 and moves along the Y-axis. The gripping frame 62 is slidably connected to the movable frame 61 and moves along the Z-axis. Two vacuum nozzles 63 are fixedly connected to the gripping frame 62 for placing or removing floating beans from the floating seat. In some embodiments, threading... A fixed frame is fixedly connected to the platform 20. The movable frame 61 is slidably connected to the fixed frame via a sliding table cylinder. A telescopic cylinder is fixedly connected to the movable frame 61. The piston rod of the telescopic cylinder is fixedly connected to the gripping frame 62. Thus, with the cooperation of the sliding table cylinder and the telescopic cylinder, the gripping frame 62 can move along the Y-axis and Z-axis of the fixed frame, thereby grabbing the floating beans on the material tray 54 onto the floating bean holder 31, and then grabbing the floating beans with threaded wire on the floating bean holder 31 onto the conveying device 70.

[0050] A conveying device 70 is provided on the threading table 20. The conveying device 70 includes a conveying frame 71 and a conveyor belt 72. The conveying frame 71 is fixedly connected to the threading table 20, and the conveyor belt 72 is drivenly connected to the conveying frame 71 for conveying the threaded beans. In some embodiments, a geared motor is fixedly connected to the conveying frame 71, and the output shaft of the geared motor is drivenly connected to the belt roller on the conveying frame 71. Under the driving action of the geared motor, the conveyor belt 72 is conveyed, thereby conveying the threaded beans.

[0051] In some embodiments, the feeder 50 and the gripper 60 can be used to put the float beans to be threaded into the hopper 52, so that the float beans fall one by one into the float bean trough on the tray 54. As the tray 54 rotates continuously, the gripper 60 can transfer the float beans to be threaded on the tray 54 to the float bean holder 31, and then transfer the threaded float beans to the conveying device 70, thereby improving the threading efficiency of the float beans.

[0052] The working principle of this utility model is as follows: In use, the control system of the device causes the sweeping brush 53 and the material tray 54 to rotate, so that the floating beans in the material bin 52 enter the floating bean groove on the material tray 54 in sequence. Then, the gripping frame 62 drives the two vacuum nozzles 63 to move downward, so that the rear vacuum nozzle 63 adsorbs and grips one of the floating beans on the material tray 54. After gripping, the gripping frame 62 drives the vacuum nozzle 63 to move upward to reset. Then, the vacuum nozzle 63 moves forward so that the floating bean corresponds to the floating bean groove on the floating bean seat 31. Then, the gripping frame 62 moves downward to place the floating bean on the floating bean seat 31 and release the adsorption of the floating bean.

[0053] Then, the line feeder 42 feeds the line in a square manner. At the same time, the line feeder 43 drives the line clamp 44 and the line feed tube 46 to move to the right. Under the clamping action of the line clamp 44, the fishing line can be driven to move to the right until the pneumatic gripper 410 clamps and fixes the end of the fishing line. Then, the line feeder 43 drives the line clamp 44 and the line feed tube 46 to reset.

[0054] Then, move the float bean holder 31 to the left so that the line groove on the float bean is aligned with the hook 34, and move the clamping seat 33 downward so that the clamping seat 33 presses the float bean onto the float bean holder 31. Then, move the hook 34 backward and pass through the line groove on the float bean. When the hook groove on the hook 34 is below the fishing line, move the lower pressing block 35 downward so that the fishing line is pressed onto the hook groove on the hook 34. At this time, the pneumatic scissors 411 cuts the fishing line on the left side of the hook 34, and the pneumatic clamp 410 releases the fishing line. At the same time, the hook 34 pulls the fishing line through the line groove on the float bean, thus completing the line threading operation of the float bean.

[0055] Finally, the bean holder 31 moves the threaded bean to the right to reset, and the gripper 62 moves the two vacuum nozzles 63 downward, so that the front vacuum nozzle 63 vacuum adsorbs the bean. After adsorption, the gripper 62 moves upward to reset, and then the gripper 62 moves forward and downward, and releases the vacuum adsorption of the front vacuum nozzle 63, so that the threaded bean is placed on the conveyor belt 72.

[0056] Similarly, while the rear vacuum nozzle 63 is picking up and placing the threaded float beads, the front vacuum nozzle 63 is picking up and placing the unthreaded float beads. By repeating the above steps, the automatic threading operation of the float beads is completed.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
