Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire feeding devices, specifically to a wire feeding device for plastic steel wire. Background Technology
[0002] In fruit tree and vegetable cultivation, PVC-U steel wire is frequently used for constructing supports, training branches, and securing crops due to its lightweight, high strength, and corrosion resistance. Laying out the wire is an indispensable step in its use, especially when adjustments or reinstallation are required. Currently, most wire laying devices on the market are electrically powered or have complex mechanical structures. While these improve efficiency to some extent, they are too cumbersome and complicated for small-scale operations, temporary laying, or maintenance.
[0003] Most existing wire-laying devices require a power source, are cumbersome to operate, and have a high overall cost. They also require a stable power supply, which is often insufficient or unstable for small-scale wire-laying operations in the field or remote areas, affecting both the equipment's normal operation and the wire-laying work. Furthermore, electrically powered or complex mechanical wire-laying devices are bulky and heavy, making them inconvenient to carry to different work locations. For small-scale operations or budget-constrained situations, these devices are too expensive to recoup costs quickly. To address these issues, this invention proposes a manually operated and portable wire-laying device for plastic-coated steel wire. Utility Model Content
[0004] The purpose of this utility model is to provide a wire feeding device for plastic steel wire, which adopts manual operation for wire feeding, is easy to carry, and is suitable for small-scale operation.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A wire feeding device for plastic-coated steel wire includes a base with symmetrically arranged supports. A placement seat is located on the top of each support, and a movable rod is mounted on the placement seat. Both ends of the movable rod are rotatably connected to the placement seat. A plastic-coated steel coil is sleeved on the movable rod. A fixing device for restricting the movement of the plastic-coated steel coil is provided on the outer surface of the movable rod. The fixing device includes several arc-shaped spring plates arranged circumferentially on the outer surface of the movable rod. Several grooves are formed on the outer surface of the movable rod. The two ends of each spring plate are a fixed end and a movable end, respectively. The fixed end of the spring plate is fixedly connected to the outer surface of the movable rod, and the movable end of the spring plate is slidably disposed within the groove. The base also includes a guide mechanism for guiding the plastic-coated steel wire out.
[0007] As a preferred technical solution, the base includes two crossbars and two rollers. The rollers and crossbars are arranged perpendicular to each other, and the two ends of the rollers are rotatably connected to the two crossbars through a rotating shaft.
[0008] As a preferred technical solution, the crossbar has a square pin hole, and the end faces of both ends of the rotating shaft have square slots that match the pin hole, and the pin hole has a pin that matches the pin hole.
[0009] As a preferred technical solution, the placement base is provided with a U-shaped groove for placing the movable rod. The opening of the U-shaped groove faces upward, and a number of ball bearings are provided on the arc-shaped wall at the bottom of the U-shaped groove. The ball bearings are rotatably connected to the arc-shaped wall.
[0010] As a preferred technical solution, the U-shaped groove is provided with a locking block, which is set on one side of the two placement seats facing each other. The movable rod has locking grooves at both ends that match the locking block, and the locking grooves are annular groove structures.
[0011] As a preferred technical solution, the guiding mechanism includes two vertical rods, a sliding rod, and a guide block. The vertical rods are mounted on the base, and both ends of the sliding rod are fixedly connected to the vertical rods. The guide block is sleeved on the sliding rod and is slidably connected to the sliding rod. The guide block has a through hole for the plastic steel wire to pass through.
[0012] As a preferred technical solution, the plastic-coated steel coil includes a coil and a plastic-coated steel wire, the plastic-coated steel wire being wound on the coil.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] 1. In this utility model, the wire laying is done manually without the need to connect to a power source. It is easy to operate, requires no systematic learning, and is easy to carry. It has low manufacturing cost and is suitable for small-scale or budget-limited operations.
[0015] 2. In this utility model, the base is equipped with a rotatable roller to facilitate overall movement and adapt to different work scenarios. After the square pin is inserted into the matching pin hole, it can limit the rotation of the roller and ensure that the base is stable when feeding the line.
[0016] 3. In this utility model, the circumferentially distributed spring sheet design automatically adjusts and provides uniform radial pressure during the installation of the plastic steel coil, forcing the plastic steel coil to remain coaxial with the movable rod, and the spring sheet can provide support for the plastic steel coil, effectively limiting the axial displacement and rotation of the coil, reducing friction loss, and extending the life of the wire.
[0017] 4. In this utility model, the guide mechanism controls the exit position of the plastic steel wire, ensuring that the plastic steel wire moves along the predetermined track during the wire feeding process.

[0027] Example
[0028] like Figure 1-3 As shown, a wire feeding device for plastic steel wire includes a base, on which symmetrical supports 5 are provided. A placement seat 6 is fixedly provided on the top of the supports 5. A movable rod 7 is provided on the placement seat 6. The two ends of the movable rod 7 are rotatably connected to the placement seat 6. A plastic steel coil 8 is sleeved on the movable rod 7. A fixing device for restricting the movement of the plastic steel coil 8 is provided on the outer surface of the movable rod 7, restricting the relative axial movement and rotation of the plastic steel coil 8 and the movable rod 7. The fixing device includes several arc-shaped spring plates 72, with the concave surface of the arc-shaped spring plates 72 facing the outer surface of the movable rod 7. Several spring plates 72 are arranged circumferentially on the outer surface of the movable rod 7. Several sliding grooves 73 are opened on the outer surface of the movable rod 7. The two ends of the spring plates 72 are a fixed end and a movable end, respectively. The fixed end of the spring plate 72 is fixedly connected to the movable rod 7. The movable end of the spring plate 72 is slidably disposed in the sliding groove 73. When the spring plate 72 is subjected to pressure, the spring plate 72 generates elastic deformation, causing the movable end of the spring plate 72 to move along the sliding groove 73 toward the end of the movable rod 7.
[0029] In use, the plastic steel coil 8 needs to be fitted onto the movable rod 7. The plastic steel coil 8 has a hole in the center for the movable rod 7 to pass through. It should be noted that the fixed end of the spring plate 72 should be inserted into the plastic steel coil 8 first. The hole wall in the center of the plastic steel coil 8 applies pressure evenly to several spring plates 72, so that the movable end of the spring plate 72 moves along the slide groove 73 towards the end of the movable rod 7. When the plastic steel coil 8 moves to the appropriate position, several spring plates 72 provide a uniform reaction force to the plastic steel coil 8, so that the plastic steel coil 8 and the movable rod 7 are coaxially set, and the relative axial movement and relative rotation of the plastic steel coil 8 and the movable rod 7 are restricted.
[0030] The spring plate 72 has a large elastic coefficient. Since the larger the elastic coefficient, the greater the stiffness of the spring plate 72, it can provide stronger support force. Therefore, the spring plate 72 can provide strong support force for the plastic steel coil 8, ensuring that the plastic steel coil 8 and the movable rod 7 are coaxially set, and restricting the relative movement and rotation of the two.
[0031] The base is also equipped with a guide mechanism 9 for guiding the release of the plastic steel wire 82. The guide mechanism 9 can control the exit position of the plastic steel wire 82, ensuring that the plastic steel wire 82 moves along a predetermined track during the release process, improving the release accuracy and quality, and reducing the phenomenon of tangling and knotting of the plastic steel wire 82. The guide mechanism 9 includes two vertical rods 91, a sliding rod 92, and a guide block 93. The vertical rods 91 are set on the base, and both ends of the sliding rod 92 are fixedly connected to the vertical rods 91. The guide block 93 is sleeved on the sliding rod 92 and is slidably connected to the sliding rod 92. The guide block 93 has a through hole 94 for the plastic steel wire 82 to pass through. The plastic steel wire 82 is passed through the through hole 94 before release. The exit position of the plastic steel wire 82 can be controlled, and the guide block 93 can slide on the sliding rod 92, so the appropriate exit position can be adjusted according to the working position.
[0032] The slide bar 92 is provided with a limiting groove, and the wire block 93 is provided with a limiting block that matches the slide groove 73. The limiting block can slide in the limiting groove. The cooperation between the limiting block and the limiting groove can limit the relative rotation between the wire block 93 and the slide bar 92, so as to prevent the wire block 93 from rotating relative to the slide bar 92 under force when assisting in wire output.
[0033] The conductor block 93 is provided with a threaded hole, and a bolt is connected to the threaded hole. When the bolt is tightened, the end of the bolt passes through the bolt hole and abuts against the slide rod, which can restrict the left and right movement of the conductor block 93, so that the conductor block 93 is fixed on the slide rod 92. When the bolt is loosened, the conductor block 93 is not restricted and can move relative to the slide rod 92, so that the conductor block 93 moves to a suitable wire outlet position.
[0034] In some feasible embodiments, the base includes two crossbars 1 and two rollers 2. The rollers 2 are arranged perpendicularly to the crossbars 1. The two ends of the rollers 2 are rotatably connected to the two crossbars 1 via rotating shafts 3, allowing the base to move on the ground and avoiding the need for handling during the laying process. The bottom of the rollers 2 extends beyond the bottom of the crossbars 1, ensuring that the rollers 2 can contact the ground and roll on the ground to move the base.
[0035] In some feasible embodiments, a square pin hole is provided on the crossbar 1, and a square slot matching the pin hole is provided on the end face of both ends of the rotating shaft 3. A pin 4 matching the pin hole is provided in the pin hole, and one end of the pin 4 is inserted into the slot. Since the pin 4, the pin hole and the slot are all square, the relative rotation of the rotating shaft 3 and the crossbar 1 can be restricted, so that the roller 2 cannot rotate, and the base can be fixedly placed on the ground and will not move due to the tension generated during the laying of the line.
[0036] The placement seat 6 has a U-shaped groove for placing the movable rod 7. The opening of the U-shaped groove faces upward, making it easy to place the movable rod 7 on the placement seat 6. Several balls 62 are provided on the arc-shaped wall at the bottom of the U-shaped groove. The balls 62 are rotatably connected to the arc-shaped wall. The balls 62 can reduce the friction between the movable rod 7 and the wall of the U-shaped groove, making it easier to lay out the line.
[0037] In some feasible embodiments, a locking block 61 is provided in the U-shaped groove. The locking block 61 is set on one side of the two placement seats 6 facing each other. The movable rod 7 has a locking groove 71 at both ends that matches the locking block 61. The locking groove 71 is an annular groove structure. When the movable rod 7 is placed, the locking blocks 61 on both sides are locked into the locking groove 71 at both ends of the movable rod 7. When the movable rod 7 rotates relative to the U-shaped groove, the locking block 61 rotates relative to the locking groove 71, which can limit the axial displacement of the movable rod 7 and prevent the movable rod 7 and the plastic steel coil 8 on the movable rod 7 from moving during wire feeding, so as to prevent the plastic steel wire 82 from colliding or rubbing with other components, affecting the performance and service life of the plastic steel wire 82.
[0038] The plastic steel coil 8 includes a coil 81 and a plastic steel wire 82, with the plastic steel wire 82 wound on the coil 81.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
