Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire winding machine technology for prestressed concrete pipes, and in particular to the improvement of the structure of the wire winding machine. Background Technology
[0002] like Figure 5-6 As shown, in the prior art, in order to wind prestressed steel wire around the outer wall of the core of RCP (reinforced concrete drainage pipe) or PCCP (prestressed concrete cylinder pipe), the prestressed steel wire purchased from the market needs to be placed on a special wire feeding spool 7 and pre-wound onto a double-spool wire winding machine. Wire winding spool 1 (2) and wire winding spool 2 (3) can be used alternately. For example, wire winding spool 1 (2) is used to supply the required prestressed steel wire to the entire wire winding machine, while wire winding spool 2 (3) is used for pre-winding. When wire winding spool 1 (2) is working, the steel wire on the wire feeding spool 7 can be pre-wound onto wire winding spool 2 (3).
[0003] During normal production, the wire winding machine places the steel wire on the wire feeding tray 7 and moves unidirectionally between the stress mechanisms of the double-drum wire winding machine to wind the steel wire onto the pre-wound core 8. However, in special circumstances, wire unwinding is required, such as when the wire suddenly breaks, during trial production and equipment debugging, or when the remaining steel wire on the double-drum wire winding machine cannot meet the needs of the existing core and intermediate wire winding is required.
[0004] The existing equipment lacks a corresponding device for wire unwinding, which leads to uneven distribution of steel wires on the winding drum, thus affecting the tension of the steel wires on the winding drum. Especially as the market demands for concrete pipes continue to increase, the diameter of the prestressed steel wires used has increased from the conventional φ3-5mm to φ6-10mm, which places higher demands on the prestressed steel wires at any stage. Summary of the Invention
[0005] To address the above problems, this utility model provides a wire unwinding and unwinding device that ensures neat winding and uniform winding tension when the winding machine reverses and unwinds the wire in situations requiring wire splicing.
[0006] The technical solution of this utility model is as follows: a wire unwinding and wire laying device, comprising a wire winding machine, wherein the wire winding machine includes a first wire winding drum, a second wire winding drum, a stress mechanism, and a wire feeding reel.
[0007] It also includes a wire unwinding mechanism, which includes a frame, a lifting rod, a push rod, a slide rod, and a wire unwinding device. The bottom surface of the frame is fixedly connected to the top end of the lifting rod. The push rods are respectively provided at both ends of the top surface of the frame. The slide rod is fixedly provided between the push rods at both ends. The wire unwinding device is slidably mounted on the slide rod. The wire unwinding device has a wire unwinding hole.
[0008] The wire winding mechanism is installed between the first winding drum, the second winding drum, and the stress mechanism.
[0009] Furthermore, a wire guide device is provided at the rear end of the first winding spool.
[0010] Furthermore, the rear end of the winding spool two is provided with a wire guide three.
[0011] Furthermore, a guide wheel is provided between the wiring mechanism and the stress mechanism.
[0012] Furthermore, a guide wheel is provided between the first winding drum, the second winding drum, and the wire feeding disc.
[0013] This invention effectively solves the problem of uneven wire distribution when the wire returns to the winding drum during wire unwinding in a wire winding machine, thus affecting the tension. This invention also has the beneficial effect of ensuring that the wire on the winding drum is neatly wound and the winding tension is uniform when the wire winding machine is running in reverse to unwind the wire.

[0022] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.
[0023] The following is in conjunction with the instruction manual appendix. Figure 1-4 The present invention will be further described below.
[0024] A wire unwinding and winding device includes a wire winding machine, which comprises a first winding spool 2, a second winding spool 3, a stress mechanism 6, and a wire feeding reel 7. The wire feeding reel 7 is mounted at the tail end, and the first winding spool 2 and the second winding spool 3 are mounted in front of the wire feeding reel 7, arranged one behind the other, with the center of the first winding spool 2 lower than the center of the second winding spool 3. The stress mechanism 6 is mounted in front of the first winding spool 2 and the second winding spool 3. The wire feeding reel 7 is used to place the steel wire pre-wound onto the winding spool. The steel wire on the wire feeding reel 7 is evenly wound onto the winding spool. Then, the pre-stressed steel wire on the winding spool is wound several times on the stress wheel of the stress mechanism 6 and then wound onto the pre-wound core 8. The wire winding devices one to three and the stress mechanism involved in this utility model are conventional structures and will not be described in detail.
[0025] It also includes a wire laying mechanism 1 for unwinding wires. The wire laying mechanism 1 includes a frame 11, a lifting rod 12, a push rod 13, a slide rod 14 and a wire laying device 15. The bottom surface of the frame 11 is fixedly connected to the top end of the lifting rod 12. Push rods 13 are respectively provided at both ends of the top surface of the frame 11. A slide rod 14 is fixedly provided between the push rods 13 at both ends. The wire laying device 15 is slidably mounted on the slide rod 14. The wire laying device 15 is provided with a wire laying hole 151.
[0026] The wire winding mechanism 1 is installed between the first winding drum 2, the second winding drum 3, and the stress mechanism 6.
[0027] like Figure 2 As shown, when the wire on the winding machine is wound towards the pre-wound core 8, the wire laying mechanism 1 is in a laid-down state, and the wire is wound onto the pre-wound core 8 through the stress mechanism 6. At this time, the wire laying mechanism 1 is below the wire and does not affect the normal operation of the winding machine.
[0028] like Figure 3 As shown, when the wire on the winding drum 2 needs to be unwound, the push rod 13 is activated so that the wire can pass through the wire guide hole 151 on the wire guide 15. At this time, the wire is wound onto the winding drum 2 in the required order through the wire guide hole 151.
[0029] like Figure 4As shown, when the wire on the winding drum 3 needs to be unwound, the lifting rod 12 and the pushing rod 13 are activated so that the wire can pass through the wire feeding hole 151 on the wire feeder 15. At this time, the wire is wound on the winding drum 3 in the required order through the wire feeding hole 151.
[0030] Furthermore, the rear end of the winding spool 2 is equipped with a wire guide 21. This ensures that the steel wire on the wire feeding spool 7 is evenly distributed when it is wound onto the winding spool 2 through the wire guide hole 211, thus ensuring the tension on the winding spool.
[0031] Furthermore, the rear end of the winding spool 2 3 is provided with a wire guide 3 31. This ensures that the steel wire on the wire feeding spool 7 is evenly distributed when it is wound onto the winding spool 2 3 through the wire guide hole 3 311, thus ensuring the tension on the winding spool.
[0032] Furthermore, a guide wheel 4 is installed between the wiring mechanism 1 and the stress mechanism 6.
[0033] Furthermore, a guide wheel 5 is installed between the first winding spool 2, the second winding spool 3, and the wire feeding spool 7. The guide wheel 4 and the guide wheel 2 are used to constrain the direction of the steel wire and prevent the steel wire from scattering.
