[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1:

[0017] like Figures 1-4As shown, this utility model discloses a yarn guide frame for a rapier loom, including a base 1, a sliding groove 2 on the base 1, and two support columns 3 arranged in the sliding groove 2. The support columns 3 are slidably connected to the base 1. A drive motor 10 is arranged on the base 1, and a lead screw 11 is arranged at the output end of the drive motor 10. The lead screw 11 extends and passes through the two support columns 3. The lead screw 11 is divided into two parts with opposite thread directions. The lead screw 11 is threadedly connected to the support columns 3, and the two support columns 3 are respectively connected to the two parts of the lead screw 11 with opposite thread directions. A horizontal shaft 4 is arranged at the same height on the inner side of the two support columns 3. A conical body 5 is rotatably arranged at the end of the horizontal shaft 4. The two conical bodies 5 are used to clamp the yarn bobbin. A lifting mechanism is arranged on the frame between the two support columns 3. A V-shaped support 7 is arranged on the lifting mechanism. The V-shaped support 7 extends directly below the position between the two conical bodies 5.

[0018] A sliding groove 2 is provided on the base 1. The sliding groove 2 can have a dovetail structure. The lower end of the support column 3 is slidably connected to the sliding groove 2, and the support column 3 can slide freely within the sliding groove 2. A drive motor 10 is provided at one end of the base 1, which can drive the lead screw 11 to rotate. The lead screw 11 is formed by two parts joined together, and the threads of the two parts of the lead screw 11 are opposite in direction. When the drive motor 10 drives the lead screw 11 to rotate, it can drive the two support columns 3 to move closer or further apart. The V-shaped support bracket 7 is located between the two support columns 3 and directly below the cone 5. That is, when the yarn bobbin is placed on the V-shaped support bracket 7, the center of the yarn bobbin and the center of the cone 5 are in the same vertical plane. Thus, only the height of the yarn bobbin needs to be adjusted to make the cone 5 and the yarn bobbin in a straight line for easy assembly. Therefore, in actual operation, the yarn bobbin only needs to be placed on the V-shaped support 7. The V-shaped support 7 can position the yarn bobbin. After positioning, the yarn bobbin is lifted by the lifting mechanism to the same height as the conical body 5. At this time, the drive motor 10 drives the two support columns 3 to approach, and the end of the conical body 5 is inserted into the yarn bobbin to clamp it. Since the conical body 5 and the horizontal axis 4 are free to rotate, the conical body 5 on the horizontal axis 4 can rotate with the yarn bobbin to deliver yarn.

[0019] A horizontal through hole 17 is provided on the horizontal shaft 4 and the conical body 5, the horizontal through hole 17 passing through the two horizontal shafts 4 and the two conical bodies 5. An infrared transmitter 14 and an infrared receiver 19 are respectively fixedly installed at the ends of the two horizontal shafts 4. A controller is also included, which is connected to the infrared transmitter 14, the infrared receiver 19, the lifting mechanism, and the drive motor 10. To improve the level of automation, a through hole 17 is provided in the middle of the horizontal shafts 4 and the conical bodies 5. Since the heights of the two horizontal shafts 4 are the same, the central axes of the through holes 17 on the two horizontal shafts 4 coincide. An infrared transmitter 14 and an infrared receiver 19 are respectively fixed at the ends of the horizontal shafts 4 and connected to the controller. During the actual yarn bobbin replacement process, after the yarn bobbin is placed on the V-shaped support 7, the yarn on the bobbin will block the infrared light emitted by the infrared emitter 14. At this time, the controller can control the lifting mechanism to drive the V-shaped support 7 to rise until the center hole of the yarn bobbin is at the same horizontal position as the through hole 17 on the horizontal shaft 4. Then, the infrared light emitted by the infrared emitter 14 passes through the through hole 17 and the center hole of the yarn bobbin in sequence and is sensed by the infrared receiver 19. At this time, it can be determined that the cone 5 corresponds to the yarn bobbin. The drive motor 10 drives the lead screw 11 to rotate, and the two support columns 3 move closer to each other so that the cone 5 is inserted into the center hole of the yarn bobbin and clamps the yarn bobbin. After completion, the infrared emitter 14 stops working, and the lifting mechanism drives the V-shaped support 7 to descend, so as to avoid the V-shaped support 7 interfering with the output of the yarn.

[0020] The above design enables automatic alignment and clamping of the yarn bobbin, achieving a high degree of automation and ensuring a safe and reliable clamping process. Operation is simple and convenient; personnel only need to place the yarn bobbin on the V-shaped support 7.

[0021] The V-shaped support 7 is provided with several horizontal guide rollers 8 at intervals. The horizontal guide rollers 8 rotate freely on the V-shaped support 7 and are distributed in a V-shape on the V-shaped support 7. The design of the horizontal guide rollers 8 allows the yarn bobbin to slide to the bottom better under the action of gravity and maintain a horizontal state, and the yarn bobbin and the conical body 5 can also be better supported.

[0022] The lifting mechanism includes a column 6 and a vertical guide groove 15 disposed on the column 6. The end of the V-shaped support 7 extends into the guide groove 15, and the V-shaped support 7 is slidably connected to the guide groove 15. A vertical screw 16 is disposed in the guide groove 15 on the column 6, and the end of the V-shaped support 7 is threadedly connected to the screw 16. A lifting motor 9 is disposed at the top of the column 6, and the lifting motor 9 is drivenly connected to the screw 16. Through the design of the lifting motor 9 and the screw 16, the V-shaped support 7 can be lifted and lowered within the guide groove 15, thereby changing the position of the V-shaped support 7 and making adjustment convenient.

[0023] The horizontal shaft 4 is slidably connected to the support column 3. An annular protrusion 12 is provided on the horizontal shaft 4 between the support column 3 and the conical body 5. A compression spring 13 is sleeved on the horizontal shaft 4 between the annular protrusion 12 and the support column 3. The two ends of the compression spring 13 are fixed to the support column 3 and the annular protrusion 12, respectively. To maintain stable and reliable clamping between the conical body 5 and the yarn bobbin without damaging the yarn bobbin, the horizontal shaft 4 and the support column 3 are designed to slide freely. The compression spring 13, sleeved on the horizontal shaft 4 between the annular protrusion 12 and the support column 3, allows the compression spring 13 to adaptively adjust the pressure when the support column 3 approaches and the conical body 5 applies pressure to the yarn bobbin, preventing damage from hard compression and maintaining stable clamping force. Furthermore, the two ends of the compression spring 13 are fixedly connected to the support column 3 and the annular protrusion 12, effectively ensuring the connection between the horizontal shaft 4 and the support column 3, preventing detachment, and ensuring safe and reliable sliding.

[0024] Several grooves are spaced apart on the circumferential surface of the cone 5, and rubber strips 18 are embedded in the grooves, with the surface of the rubber strips 18 protruding from the surface of the cone 5.

[0025] A groove is provided on the surface of the cone 5 and a rubber strip 18 is embedded therein. When the cone 5 is connected with the yarn tube, the rubber strip 18 can play a buffering role to avoid excessive compression and damage to the yarn tube.
