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.

[0023] Please see Figures 1-5This utility model provides a technical solution: a drawing frame suitable for yarn production includes a drawing frame body 1 and an upper wire frame 2 set at the rear. A loading and unloading mechanism is set at the front of the drawing frame body 1, and the loading and unloading mechanism corresponds to the position of the wire outlet of the drawing frame body 1. The loading and unloading mechanism includes a switching disk 5, a drive component 7, a loading component 8 and an unloading component 9.

[0024] A support plate 3 is fixedly connected to the front of the main body 1 of the drawing frame, and a main shaft 4 is rotatably connected to the top of the support plate 3. The switching plate 5 is fixedly connected to the top of the main shaft 4. The drive assembly 7 is located below the switching plate 5 and is used to drive the switching plate 5 to rotate intermittently. The feeding assembly 8 is located on the right side of the switching plate 5 and is used to feed the empty yarn bobbins one by one into the switching plate 5. The front of the main body 1 of the drawing frame is provided with a feeding assembly 9, which is used to feed the collected bobbins after collection. The top of the switching plate 5 is provided with multiple sets of clamping assemblies 6, which are used to clamp and stabilize the collected bobbins entering the switching plate 5.

[0025] The drive assembly 7 includes a driven gear 71 and a drive motor 72. The driven gear 71 is fixedly connected to the surface of the main shaft 4. The drive motor 72 is fixedly connected to the bottom of the support plate 3. The output end of the drive motor 72 is fixedly connected to a drive gear 73. The drive gear 73 meshes with the driven gear 71 for transmission. A support rod 74 is fixedly connected to the top of the support plate 3. A height detection sensor 75 is fixedly installed on the top of the support rod 74 through a bracket. A controller 10 is set in front of the loading assembly 8. The height detection sensor 75 is electrically connected to the controller 10. The drive assembly 7, the loading assembly 8, and the unloading assembly 9 are all controlled by the controller 10.

[0026] The feeding assembly 8 includes a feeding rack 81. A second groove 82 is provided at the bottom of the inner wall of the feeding rack 81. A first arc-shaped push plate 83 is slidably connected to the inner surface of the second groove 82. Two rotating seats 84 are fixedly connected to the bottom of the feeding rack 81, and a lead screw 85 is rotatably connected between the two rotating seats 84. The first arc-shaped push plate 83 is threadedly connected to the surface of the lead screw 85. An input motor 86 is fixedly connected to the right side of the right rotating seat 84, and the output end of the input motor 86 is fixedly connected to one end of the lead screw 85.

[0027] The unloading assembly 9 includes multiple third slides 91 and an unloading rack 96 that are equidistantly opened inside the switching plate 5. An L-shaped slide plate 92 is slidably connected to the inner surface of the third slide 91. A second arc-shaped push plate 93 is fixedly connected to the top of the L-shaped slide plate 92. An electric push rod 94 is fixedly connected to the bottom of the support plate 3. The telescopic end of the electric push rod 94 is fixedly connected to a push block 95 that cooperates with the L-shaped slide plate 92 through an L-shaped rod. The unloading rack 96 is placed in front of the switching plate 5.

[0028] When the drawing frame collects the drawn yarn, the loading and unloading mechanism enables the collecting cylinder to automatically enter below the yarn outlet. After collection, the empty cylinder is automatically switched, and the yarn is unloaded when the collecting cylinder rotates to the unloading position. The whole process is completed automatically with high continuity, which improves the automation level of the device.

[0029] The clamping assembly 6 includes two first slide grooves 61 on the top of the switching disk 5. The inner surfaces of the two first slide grooves 61 are slidably connected to clamping plates 62, and a return spring 63 is fixedly connected between the clamping plates 62 and the inner wall of the first slide grooves 61.

[0030] A clamping component 6 is installed on the switching plate 5 to clamp and stabilize the collecting cylinder entering the switching plate 5, ensuring the stability of the collecting cylinder during the switching process and ensuring the stable operation of the loading and unloading mechanism.

[0031] In use, the collection cylinders are placed inside the loading rack 81. The input motor 86 is started, causing the lead screw 85 to rotate. The rotation of the lead screw 85 moves the first arc-shaped push plate 83, thereby sending the leftmost collection cylinder to the top of the switching disk 5. During the process of the collection cylinder entering the top of the switching disk 5, the collection cylinder contacts the two clamping plates 62 and pushes the two clamping plates 62 away from each other. After the collection cylinder enters between the two clamping plates 62, the two clamping plates 62 are clamped to the outside of the collection cylinder by the action of the return spring 63. At this time, the drive motor 72 works and causes the drive gear 73 to rotate. The drive gear 73 rotates and transmits power to the driven gear 71. The driven gear 71 rotates and transmits power to the driven gear 71. Shaft 4 drives the switching disc 5 to rotate, causing the collecting cylinder to enter below the outlet of the drawing frame body 1, at which point the collecting process can begin. The feeding assembly 8 is activated again to send the empty cylinder onto the switching disc 5. The height detection sensor 75 detects the height of the yarn in the collecting cylinder. When the preset height is reached, the drive assembly 7 works again, causing the empty cylinder to enter below the outlet of the drawing frame body 1 for collection again. When the collecting cylinder enters the position of the unloading assembly 9, the electric push rod 94 is activated, causing the push block 95 to contact the L-shaped slide plate 92 and push the second arc-shaped push plate 93 to move. The movement of the second arc-shaped push plate 93 pushes the collecting cylinder into the unloading rack 96, thus completing the unloading process.
