Description

Technical Field

[0001] The utility model relates to the technical field of needle threading machine production, in particular to a semi-automatic needle threading machine. Background Art

[0002] Embroidery involves using a needle to thread silk or other fibers or yarns into a patterned and colored material, creating decorative patterns. During the embroidery process, thread is passed through the eye of the needle. Threading the needle is a delicate process that requires close coordination between the threader's eyes and hands. However, some people, due to poor vision, cannot thread the needle independently and require the use of auxiliary tools.

[0003] The utility model with publication number CN 211311826 U discloses a semi-automatic needle threading machine, comprising a base plate, a guide block and a needle fixing block arranged at intervals on the upper end surface of the base plate along the length direction of the base plate; the guide block is provided with a first through hole extending along the length direction of the base plate, and a sliding rod is inserted into the first through hole; however, in the above design, it is difficult to achieve that the fixing plate adapts to needle rows of different sizes through the mutual cooperation of components such as the base plate and the guide block, resulting in the needle being unable to stably penetrate the top of the fixer, making the subsequent needle threading work unable to be more convenient, and resulting in the staff being unable to arrange the needles before threading, which needs to be improved.

This design is conducive to the clamping plate being able to retract to the inner wall of the rectangular groove through the elastic force of the spring.

[0007] There are two fixing plates arranged in a circumferential array on the circumferential surface of the force ring. The side cross-section of the fixing plates is L-shaped. This design is conducive to the fixing plates being able to support and clamp the needle row.

[0008] A positioning device is provided on the top of the support plate, and the positioning device includes a fixing ring, which is fixedly connected to the telescopic end of the electric telescopic rod, the circumferential surface of the fixing ring is fixedly connected to the force-bearing plate, the side surface of the force-bearing plate is fixedly connected to the connecting plate, and the inner wall of the connecting plate is rotatably connected to the rotating shaft. Such a design is conducive to driving the fixing ring to perform reciprocating linear motion when the electric telescopic rod performs reciprocating linear motion.

[0009] The circumferential surface of the rotating shaft is fixedly connected to a force-bearing rod, and the end of the force-bearing rod away from the rotating shaft is fixedly connected to a rotating rod. The inner wall of the rotating rod is rotatably connected to an action block, and the side of the action block is fixedly connected to a push plate.

[0013] The working principle and beneficial effects of the utility model are as follows:

[0014] The utility model realizes that when the clamping plate is subjected to force, the clamping plate is forced to retract into the inner wall of the rectangular groove, so that the fixing plate can support and clamp the needle row.

[0015] The utility model realizes that when the rotating shaft, the force-bearing rod, the rotating rod, the action block and other components cooperate with each other, when the rotating shaft makes a linear motion downward, the force-bearing rod is forced to make an arc motion through the circumferential surface of the rotating rod, thereby forcing the action block to slide on the top of the support plate under the force, so that the push plate slides on the inner wall of the slide groove, thereby positioning and clamping the holder, making it easy for the needle row to insert the needle into the top of the holder, so that the staff can thread the needle with the needle inserted on the top of the holder later, so that the needle threading auxiliary device can complete its work smoothly, and the work efficiency of the staff is improved.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, this embodiment provides a semi-automatic needle threading machine, including a support plate 1, a heat sink 2 fixedly connected to the top of the support plate 1, a connecting rod 3 fixedly connected to the top of the heat sink 2, a control panel 4 provided at the end of the connecting rod 3 away from the heat sink 2, a button 5 provided on the front side of the control panel 4, and a needle threading auxiliary device 6 provided on the top of the support plate 1. The needle threading auxiliary device 6 includes an electric telescopic rod 61, which is arranged at the bottom of the control panel 4. The telescopic end of the electric telescopic rod 61 is fixedly connected to a force ring 62, the circumferential surface of the force ring 62 is provided with a rectangular groove 63, and the inner wall of the rectangular groove 63 is fixedly connected to a spring 64. The end of the spring 64 away from the inner wall of the rectangular groove 63 is fixedly connected to a clamping plate 65, the front side of the clamping plate 65 is fixedly connected to a fixing plate 66, the inner wall of the fixing plate 66 is provided with a needle row 67, and the side of the fixing plate 66 is fixedly connected to a pull ring 68. This design facilitates the retraction of the clamping plate 65 into the inner wall of the rectangular groove 63 by the elastic force of the spring 64. There are two fixing plates 66 arranged in a circumferential array on the circumferential surface of the force ring 62 . The side cross-section of the fixing plates 66 is L-shaped. This design is conducive to the fixing plates 66 being able to support and clamp the needle row 67 .

[0027] In this embodiment, before the staff needs to thread the needle with the needle threading machine, the staff needs to first fix the needle in the holder 8. Later, when threading the needle with the needle threading machine, the staff needs to turn on the external power supply to energize the needle threading machine body. The staff controls the extension and retraction of the electric telescopic rod 61 through the button 5. Before the staff presses the button 5, the staff needs to pull the pull ring 68 so that the pull ring 68 is forced to drive the fixed plate 66, so that the fixed plate 66 is pulled to drive the card plate 65 to open through the spring 64. The staff replaces the component originally used for threading the needle with the needle row 67, places the needle row 67 on the inner wall of the fixed plate 66, and then releases it. The pull ring 68 makes the pull ring 68 lose its tension, thereby forcing the fixed plate 66 to drive the card plate 65 to clamp the needle row 67 again using the spring 64. When the card plate 65 is under force, the card plate 65 is forced to retract into the inner wall of the rectangular groove 63, so that the fixed plate 66 can support and clamp the needle row 67. Subsequently, the staff controls the electric telescopic rod 61 to extend through the button 5, and inserts the needles in the needle row 67 into the top of the holder 8, so that the fixed plate 66 can adapt to needle rows 67 of different sizes, and the needles can be stably inserted into the top of the holder 8, paving the way for the subsequent needle threading work, making it convenient for the staff to organize the needles before threading, and reducing the staff's workload.

[0028] Example 2

[0029] like Figures 1 to 5As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the top of the support plate 1 is provided with a positioning device 7. The positioning device 7 includes a fixing ring 71, which is fixedly connected to the telescopic end of the electric telescopic rod 61. The circumferential surface of the fixing ring 71 is fixedly connected to a force-bearing plate 72. The side of the force-bearing plate 72 is fixedly connected to a connecting plate 73. The inner wall of the connecting plate 73 is rotatably connected to a rotating shaft 74. This design facilitates the reciprocating linear motion of the electric telescopic rod 61 to drive the fixing ring 71 to reciprocate. The circumferential surface of the rotating shaft 74 is fixedly connected to a force-bearing rod 75. The end of the force-bearing rod 75 away from the rotating shaft 74 is fixedly connected to a rotating rod 76. The inner wall of the rotating rod 76 is rotatably connected to an action block 77. The side of the action block 77 is fixedly connected to a push plate 78. A sliding groove 79 is provided on the top of the support plate 1. This design facilitates the rotating shaft 74 to force the force-bearing rod 75 to move in an arc through the rotating rod 76 when the rotating shaft 74 follows the connecting plate 73 to reciprocate linearly. The side cross-section of the action block 77 is concave, and the action block 77 is slidably connected to the top of the support plate 1. The side cross-section of the push plate 78 is T-shaped. This design facilitates forcing the action block 77 to slide on the top of the support plate 1 when the force rod 75 makes an arcuate motion. The side cross-section of the connecting plate 73 is I-shaped, and two rotating shafts 74 are provided, symmetrically arranged along the vertical center axis of the bottom of the connecting plate 73. This design facilitates the rotating shaft 74 to also make an arcuate motion when the rotating shaft 74 forces the force rod 75 to make an arcuate motion. The button 5 is electrically connected to the electric telescopic rod 61, and the support plate 1 is provided with a conveying function. This design facilitates the smooth insertion of the needle into the top of the holder 8 after the holder 8 is positioned.

[0030] When the fixing ring 71 moves linearly downward, the force-bearing plate 72 is driven to move linearly downward, forcing the connecting plate 73 to move with the force-bearing plate 72 under the force. When the connecting plate 73 moves downward, the rotating shaft 74 is prompted to move linearly downward. When the rotating shaft 74 moves linearly downward, the force-bearing rod 75 is forced to move in an arc shape through the circumferential surface of the rotating rod 76, thereby forcing the action block 77 to slide on the top of the support plate 1 under the force, thereby causing the push plate 78 to slide on the inner wall of the slide groove 79, thereby positioning and clamping the fixture 8, so that the needle row 67 can insert the needle into the top of the fixture 8, so that the staff can thread the needle on the needle stuck on the top of the fixture 8 later, so that the needle threading auxiliary device 6 can complete its work smoothly, thereby improving the work efficiency of the staff.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
