Description

Technical Field

[0001] This utility model relates to the field of general equipment, and in particular to a wire frame used in a vertical I-beam reel wire feeding machine. Background Technology

[0002] In the process of producing yarn, to solve the problems of uneven tension and poor yarn feeding stability in traditional horizontal yarn feeding, a vertical I-beam reel yarn feeding machine is usually chosen. When using a vertical I-beam reel yarn feeding machine, the I-beams need to be mounted vertically on the frame. To guide the yarn, a guide wire holder needs to be installed on the I-beam reel. Currently, guide wire holders on the market include... Figure 1 As shown, it includes: a pressure plate 1, a rotating shaft 11 rotatably disposed in the pressure plate 1, a pulley 12 fixedly disposed on the rotating shaft 11, a belt 13 disposed on the pulley 12, both ends of the belt 13 being fixed to the pressure plate 1, a horizontal bar 14 passing through the pulley 12, ceramic eyelets 15 being disposed at the end of the horizontal bar 14 and at the top of the rotating shaft 11, and a through hole 16 communicating with the ceramic eyelets 15 being disposed on the side wall of the rotating shaft 11. In use, the pressure plate 1 is fastened onto the I-beam wheel 2. Under its own weight, the pressure plate 1 will be fixed on the I-beam wheel 2. Then, the wire in the I-beam wheel 2 is passed through the ceramic eye 15 on the crossbar 14, the through hole 16 on the rotating shaft 11, and the ceramic eye 15 on the rotating shaft 11 before being inserted into the relevant equipment. When there is enough wire in the I-beam wheel 2, the wire will not come into contact with the edge on the I-beam wheel 2. When there is less wire, the wire in the I-beam wheel 2 is more likely to come into contact with the edge on the I-beam wheel 2, resulting in damage to the wire. Moreover, when the I-beam wheel is in the vertical position, it is stationary. The wire is released by pulling the wire with the wire drawing equipment. During the release process, the wire will rotate with the crossbar 14, and the wire will rub against the ceramic eye 15 on the crossbar 14, which can easily cause scratches to the wire. Utility Model Content

[0003] The purpose of this invention is to provide a wire holder for a vertical I-beam reel wire feeding machine that prevents damage to the wires in the I-beam reel.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wire frame for a vertical I-beam reel wire feeding machine, comprising: a heavy pressure plate, a connecting rod shaft passing through the heavy pressure plate, a turntable mounted on the connecting rod shaft, several connecting plates evenly distributed around the circumference of the turntable, an annular tube between the connecting plates, the inner diameter of the annular tube being larger than the outer diameter of the I-beam reel, a stop bar horizontally passing through the turntable, a ceramic ring mounted on the stop bar, a pressure plate keyed to the connecting rod shaft located above the turntable, a felt mat placed between the pressure plate and the turntable, a spring mounted on the connecting rod shaft, the spring abutting against the pressure plate, and an adjusting handle threadedly connected to the connecting rod shaft, the adjusting handle abutting against the spring.

[0005] Furthermore, in the aforementioned wire frame used in the vertical I-beam reel wire feeding machine, the connection structure between the pressure plate and the connecting rod shaft is as follows: a shoulder and a threaded section are provided on the lower section of the connecting rod shaft, and a connecting hole is opened at the center of the pressure plate. The threaded section of the connecting rod shaft passes through the connecting hole of the pressure plate and is threadedly connected to the locking nut. The locking nut abuts against the pressure plate through an elastic washer, and the shoulder on the connecting rod shaft abuts against the pressure plate. The locking nut, in conjunction with the shoulder, fixes the connecting rod shaft to the pressure plate.

[0006] Furthermore, in the aforementioned wire frame used in a vertical I-beam reel wire feeding machine, a bearing is provided in the turntable, the connecting rod shaft is connected to the bearing, and the bearing abuts against the shoulder of the connecting rod shaft.

[0007] Furthermore, in the aforementioned wire frame used in a vertical I-beam reel wire feeding machine, a positioning ring coaxial with the pressure plate is provided extending downwards on the pressure plate.

[0008] Furthermore, in the aforementioned wire frame used in the vertical I-beam reel wire feeding machine, a bending portion is bent downward and outward on the connecting plate, and the bending portion on the connecting plate is welded to the top wall of the ring tube.

[0009] Furthermore, in the aforementioned wire frame used in the vertical I-beam reel wire feeding machine, a triangular handle is welded onto the stop bar, the triangular handle does not protrude from the bend of the connecting plate, a horizontal threaded section is provided on the stop bar, one end of the ceramic ring abuts against the triangular handle, and a set nut is threaded onto the horizontal threaded section, the set nut abuts against the other end of the ceramic ring.

[0010] Furthermore, in the aforementioned wire support used in a vertical I-beam reel wire feeding machine, a set bolt is threaded onto the pressure plate and abuts against the connecting rod shaft.

[0011] The advantages of this invention are: by using the ring tube to prevent the wire in the I-beam wheel from contacting the upper stop edge on the I-beam wheel, the wire can be prevented from being scratched by the upper stop edge; the friction between the pressure plate and the turntable can be adjusted by adjusting the deformation of the spring by the adjusting handle, thereby adjusting the tension of the wire during feeding.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figures 2 to 4 As shown, the wire frame for a vertical I-beam reel wire feeding machine of this utility model includes: a pressure plate 1, a positioning ring 17 extending downward on the pressure plate 1 and coaxial with the pressure plate 1, and a connecting rod shaft 3 passing through the pressure plate 1. The connection structure between the pressure plate 1 and the connecting rod shaft 3 is as follows: a shoulder 31 and a lower threaded section are provided in the lower section of the connecting rod shaft 3, and a connecting hole is opened at the center of the pressure plate 1. The lower threaded section of the connecting rod shaft 3 passes through the connecting hole of the pressure plate 1 and is threadedly connected to a locking nut 32. The locking nut 32 abuts against the pressure plate 1 through an elastic washer, and the shoulder 31 on the connecting rod shaft 3 abuts against the pressure plate 1. The locking nut 32, together with the shoulder 31, fixes the connecting rod shaft 3 to the pressure plate 1. A turntable 4 is mounted on the connecting rod shaft 3, and a bearing 41 is installed in the turntable 4. The connecting rod shaft 3 is connected to the bearing 41, and the bearing 41 abuts against the shoulder 31 of the connecting rod shaft 3. Several connecting plates 42 are evenly distributed around the circumference of the turntable 4. The connecting plates 42 have bends 421 that bend downwards and outwards. A ring tube 43 is welded between the bends 421 of each connecting plate 42. The bends 421 are welded to the top wall of the ring tube 43. The inner diameter of the ring tube 43 is larger than the outer diameter of the I-beam 2, and it passes horizontally through the turntable 4. A stop bar 5 is provided, and a triangular handle 51 is welded onto the stop bar 5. The triangular handle 51 does not protrude from the bend of the connecting plate 42. A horizontal threaded section is provided on the stop bar 5 on the same side as the triangular handle 51. A ceramic ring 52 is fitted on the horizontal threaded section. One end of the ceramic ring 52 abuts against the triangular handle 51. A set nut 53 is threaded onto the horizontal threaded section. The set nut 53 abuts against the other end of the ceramic ring 52. The set nut 53, together with the triangular handle 51, can fix the ceramic ring 52. A pressure plate 6 is keyed to the connecting rod shaft 3 located above the turntable 4. A set bolt 61 is threaded onto the pressure plate 6 and abuts against the connecting rod shaft 3. A felt 7 is placed between the pressure plate 6 and the turntable 4. A spring 8 is fitted onto the connecting rod shaft 3 and abuts against the pressure plate 6. An adjusting handle 33 is threaded onto the connecting rod shaft 3 and abuts against the spring 8. The compression of the spring 8 can be adjusted by adjusting the handle 33. The spring force of the spring 8 pushes the pressure plate 6, thereby adjusting the friction between the pressure plate 6 and the turntable 4. Then, the set bolt 61 is used to fix the pressure plate 6, so that the pressure plate 6 and the turntable 4 maintain a stable friction.

[0018] In use, the positioning ring 17 on the pressure plate 1 of the wire frame described in this utility model is inserted into the shaft hole on the I-beam 2. The pressure plate 1 abuts against the upper stop edge of the I-beam 2. The ring tube 43 is located outside the I-beam 2 and below the upper stop edge of the I-beam 2. Then, the wire in the I-beam 2 is pulled outward, first abutting against the ring tube 43, then against the ceramic ring 52, and finally extending into the relevant equipment. During the wire feeding process, the wire in the I-beam spool 2 moves in a circular motion along the ring tube 43. Since the ring tube 43 is lower than the upper stop of the I-beam spool 2, the pulled-out wire only contacts the ring tube 43 and not the upper stop of the I-beam spool 2. The ring tube 43 is formed by bending a round tube, and the bent part 421 on the connecting plate 42 is obliquely welded to the top wall of the ring tube 43. Therefore, when the wire contacts the ring tube 43, the connecting plate 42 will not interfere with the wire, and the ring tube 43 will not wear down the wire. Because the ring tube 43 positions the wire and restricts the upward path of the wire, when the wire is pulled upward, it can only contact the ceramic ring 52, preventing the wire from being scratched. The wire moves in a circular motion... During the cycle, the thread pushes the stop lever 5 and the turntable 4 to rotate. During the unwinding process, the thread needs to be tensioned. The friction between the pressure plate 6 and the turntable 4 is adjusted by turning the adjusting handle 33 to adjust the compression of the spring 8. When the tension of the thread is increased, turning the adjusting handle 33 compresses the spring 8 downward, thereby increasing the friction between the pressure plate 6 and the turntable 4 by increasing the elasticity of the spring 8. With increased friction, the stop lever 5 and the turntable 4 are less likely to be pushed by the thread, and the tension of the thread increases. Conversely, turning the adjusting handle 33 releases the spring 8, which reduces the friction between the pressure plate 6 and the turntable 4, making it easier for the stop lever 5 and the turntable 4 to be pushed by the thread, and reducing the tension of the thread.
