Description

Technical Field

[0001] This utility model relates to the field of fine yarn manufacturing technology, specifically to a bobbin protection device used in fine yarn spinning machines. Background Technology

[0002] A spinning frame is a machine used for spinning fine yarn. Its working principle is to process the spinning material through a series of operations, including stretching, refining, and finishing, to finally produce fine yarn. It mainly uses centrifugal force generated by rotating the spinning rod to form a spun yarn, and then uses processing rollers to finish and stretch the spun yarn, thereby refining it into fine yarn. This fine yarn has a more uniform fiber distribution and a higher fiber density, and can be used to make high-quality fabrics.

[0003] Existing bobbin protection devices used on spinning machines are mostly optimized by improving their operation, making the replacement of take-up bobbins more convenient and reducing labor costs. For example, Chinese invention patent application number CN201910250123.3 discloses "A Fully Automatic Transport Mechanism for Yarn Bobbins of a Spinning Machine". In this device, when a single or a portion of the roving roll needs to be replaced, it can be replaced, avoiding the waste of roving caused by replacing the entire row, reducing production costs. The yarn roll is placed on the track mechanism and automatically falls into the yarn roll collection box without the need for manual removal. When the conveyor moves to the rear of the yarn roll conveyor box, it can automatically put the yarn roll onto the conveyor, and the yarn roll continues to be transported to the spinning area with the conveyor belt.

[0004] While the aforementioned bobbin protection device for spinning machines offers advantages in making bobbin replacement more convenient and reducing labor costs, it still has certain drawbacks. The bobbin, installed on the device as part of the yarn winding process, is exposed to the air in spinning mill workshops where the air often contains yarn, fibers, or dust. Without protection, these particles easily adhere to the bobbin, requiring cleaning before winding. Failure to clean it promptly can negatively impact the quality of the wound yarn and the winding effect. Utility Model Content

The bobbin 41, the tilting frame 42, and the pressure roller 43 are a group that move together. There are two groups. The pressure roller 43 can adjust its distance from the outer circumference of the bobbin 41 by tilting the frame 42 to assist the bobbin 41 in winding up the fine yarn.

[0028] Please see Figure 3-4A bobbin protection device for use on a spinning machine. The protection structure 6 includes a frame plate 61, an insert plate 62, a support base 63, a plastic corrugated pipe 64, and a movable structure 65. The insert plate 62 is inserted and locked in front of the frame plate 61. The support base 63 is embedded and fixedly connected to the inner bottom surface of the frame plate 61. The upper end of the support base 63 is connected to the bottom of the movable structure 65. One end of the plastic corrugated pipe 64 is connected to the outer end surface of the movable structure 65 and is movably fitted. The movable structure 65 is movable inside the frame plate 61. The movable structure 65 includes a vertical block q1, a movable block q2, a mating component q3, a drive motor q4, an inner groove q5, and a flat plate q6. The movable block q2 is adjacent to the vertical block q1. The flat plate q6 is installed on the front end face of the inner groove q5 by screws.

The movable structure 65 moves to both sides of the cylinder 41. The plastic corrugated pipe 64 is made of polyethylene plastic and can be folded into a pleated state. When the movable structure 65 moves, it drives the plastic corrugated pipe 64 to rotate, so that it deforms in a circular trajectory. The connection between the other side of the plastic corrugated pipe 64 and the docking disc 45 allows it to move along the circular groove on the docking disc 45, thereby forming a ring-shaped protective cover outside the cylinder 41.

The transmission belt q34 is wrapped around the outer circumference of the bearing q33 and rotates. The lower end of the bearing q33 is connected to the output end of the drive motor q4 and moves. The meshing of the second gear q32 and the first gear q31 at different positions on their outer circumferences causes the second gear q32 to move around the first gear q31, assisting the movable block q2 in performing circular trajectory displacement.

[0030] In summary, during operation, the prepared fiber bundle is added to the bobbin of the spinning machine. After starting the device, the fiber bundle is transmitted to the yarn guide hole 3 via the drafting wheel 2, uniformly stretching and thinning the sliver to the required yarn count. After passing through the yarn guide hole 3, the yarn undergoes a series of stretching and combing processes, making the fibers in the fiber bundle more uniform, parallel, and of more consistent length, with better elasticity and strength. Finally, it is guided to the bobbin 41. Driven by the motor 5, the bobbin 41 rotates. With the assistance of the pressure roller 43, the spun yarn is easily wound onto the bobbin 41 according to certain forming requirements, facilitating transportation, storage, and subsequent processing. When the spinning operation is completed, there is no yarn wound onto the bobbin 41. The operator removes the insert plate 62 from the frame plate 61. One end of the plastic corrugated pipe 64 is installed on the front face of the vertical block q1 and the movable block q2, and the other end is connected to the joint of the docking disc 45. When the drive motor q4 is started, the bearing q33 rotates, which in turn causes the first gear q31 that is connected through to rotate. This drives the second gear q32 to make a circumferential displacement around the first gear q31 due to meshing. This causes the edge of the movable block q2 to always be in contact with the edge of the vertical block q1 and make a circumferential displacement until it moves to the other side of the vertical block q1. The upper end of the movable block q2 moves out of a circumferential trajectory, causing the plastic corrugated pipe 64 to unfold in a ring shape. Therefore, it forms a ring around the outside of the bobbin 41, which protects the bobbin 41 and prevents it from being exposed and easily accumulating cotton lint and dust in the spinning mill.
