Description

Technical Field

[0001] This utility model relates to the field of spinning equipment, specifically to an automatic doffing frame lifting mechanism. Background Technology

[0002] Existing rotor spinning machines require increasingly higher levels of automation to effectively improve work efficiency and reduce the labor intensity of workers. Under such demand, the automatic doffing robot for semi-automatic rotor spinning machines has emerged.

[0003] In existing technologies, traditional equipment employs two techniques for lifting and opening the yarn frame. One technique involves not lifting the yarn frame but using a cylinder to open it. After the action is completed, the yarn frame falls to the limit position by the counterforce of the pressure spring, thus determining the initial position of the yarn frame and preparing for subsequent actions. The other technique involves using a cylinder and lever mechanism to lift the yarn frame and then using the cylinder to open it.

[0004] However, the impact is large when the cylinder lever is lifted, which can easily damage the spring, damping cylinder and left arm, and even cause deformation. When not lifted, due to material and structural limitations, the doffing accuracy is low, and the yarn bobbin is easily damaged or has poor posture. Therefore, this utility model proposes an automatic doffing yarn frame lifting mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic yarn doffing frame lifting mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic doffing frame lifting mechanism, comprising: a housing, a servo motor fixedly connected to one end of the housing, the output end of the servo motor passing through one end of the housing and fixedly connected to a coupling, a lead screw fixedly connected to the end of the coupling away from the servo motor, and the other end of the lead screw rotatably connected to one end of the housing; a slide is threadedly connected to the outer surface of the lead screw, a mounting plate and a cylinder are fixedly connected to one side of the slide, a groove is opened inside the slide, a cover is slidably connected through the groove, and the two ends of the cover are fixedly connected to the two ends inside the housing.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: an automatic yarn doffing frame lifting mechanism, comprising: a housing 1, the housing 1 being made of aluminum profile, a servo motor 2 fixedly connected to one end of the housing 1, the servo motor 2 being able to precisely control the speed and torque to achieve accurate control of the lead screw 9, the output end of the servo motor 2 passing through one end of the housing 1 and fixedly connected to a coupling, the coupling being divided into a lower coupling 10 and an upper coupling 12, one side of the lower coupling 10 being fixedly connected to the output end of the servo motor 2, the end of the upper coupling 12 away from the lower coupling 10 being fixedly connected to the lead screw 9, the other end of the lead screw 9 being rotatably connected to one end of the housing 1, the lower coupling 10 and the upper coupling 12 being fixedly connected by bolts, which can directly transmit the power and torque generated by the servo motor 2 to the lead screw 9;

[0022] A slide 14 is threadedly connected to the outer surface of the lead screw 9. Grooves are formed on the upper left and right sides of the housing 1, and these grooves are slidably connected to the protruding portion at the upper end of the slide 14. A groove is formed at the bottom of the slide 14. A guide rail 13 is fixedly connected to the inside of the housing 1 near the groove, and the guide rail 13 is slidably connected to the groove. The guide rail 13 and the lead screw 9 restrict the slide 14, allowing it to rise or fall only with the rotation of the lead screw 9. A groove is formed inside the slide 14, through which a cover 3 is slidably connected. The two ends of the cover 3 are fixedly connected to the two ends inside the housing 1. The cover 3 can effectively prevent short fibers from intruding into the lead screw 9 and the guide rail 13. The mounting plate 4 and the cylinder 5 are fixedly connected to one side of the slide table 14. The mounting plate 4 is fixedly connected to the support plate 6 by bolts on the side away from the housing 1. Several round rods 8 are slidably connected inside one end of the cylinder 5. The other end of the several round rods 8 is fixedly connected to the push plate 7. The support plate 6 can lift the yarn frame with the slide table 14. After reaching the set position, the push plate 7 pushes out the yarn frame with the action of the cylinder 5.

[0023] Specifically, the servo motor 2 rotates, driving the lead screw 9 to rotate. Under the action of the lead screw 9 and the guide rail 13, the slide table 14 can move up and down. The cover 3 inside the slide table 14 can effectively prevent short fibers from intruding into the lead screw 9 and the guide rail 13. The upper support plate 6 and push plate 7 can support the yarn frame. After the slide table 14 moves together to the designated position, the cylinder 5 drives the push plate 7 to push the yarn frame out.

[0024] Example 2: Based on Example 1, as follows Figure 2 , Figure 4 As shown, an isolation plate 15 is fixedly installed inside the housing 1, separating the coupling and the lead screw 9. The isolation plate 15 is on one side of the upper coupling 12. Several hydraulic buffer platforms 11 are fixedly connected to the side of the isolation plate 15 away from the upper coupling 12. Several hydraulic buffer platforms 11 are also fixedly connected to the top of the housing 1. Each hydraulic buffer platform 11 includes a contact platform 16, a return spring 17, a cylinder 18, and a piston 19. The cylinder 18 is filled with hydraulic oil. One end of the cylinder 18 and the return spring 17 are fixedly connected to one side of the isolation plate 15. The return spring 17 surrounds the outside of the cylinder 18. The piston 19 is slidably connected to the cylinder 18. Several guide holes are opened in the middle of the piston 19. The piston 19 is fixedly connected to the contact platform 16 through the piston rod. The other end of the return spring 17 is fixedly connected to one side of the contact platform 16. When the contact platform 16 is impacted, the contact platform 16 drives the piston 19 to move inward through the piston rod. Under the action of the guide holes and the return spring 17, the impact on the housing 1 is reduced.

[0025] Specifically, when the device malfunctions, the servo motor 2 may rotate uncontrollably, causing the lead screw 9 to rotate, which in turn causes the slide 14 to impact the inside of the housing 1. The hydraulic buffer platform 11 installed inside the housing 1 can effectively reduce the impact on the housing 1 under the action of its internal piston 19 and return spring 17 and other components.

[0026] In actual use, the servo motor 2 rotates, driving the lead screw 9 to rotate. Under the action of the lead screw 9 and the guide rail 13, the slide table 14 can move up and down. The upper support plate 6 and push plate 7 can support the yarn frame. After the slide table 14 moves together to the designated position, the cylinder 5 drives the push plate 7 to push the yarn frame out. When the device malfunctions, the hydraulic buffer table 11 set inside the housing 1 can effectively reduce the impact on the housing 1 under the action of its internal piston 19 and return spring 17 and other components.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
