Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable production technology, and more specifically, it relates to a conductor frame for cable production. Background Technology
[0002] In the manufacturing process of wires and cables, it is often necessary to guide, position, and redirect multiple conductors or cable cores to ensure they enter subsequent processes such as extrusion, braiding, and cabling in an orderly manner. Traditional conductor racks are mostly fixed structures, and the position and height of their guide rollers or pulleys are usually not adjustable. However, with the diversification of cable product models, the number of conductors, arrangement spacing, and guide height required for different cable specifications vary during production.
[0003] Using fixed conductor racks has significant drawbacks: First, when producing cables of different specifications, the entire conductor rack needs to be replaced or multiple spare parts of different specifications need to be prepared, which not only increases equipment costs but also reduces production efficiency. Second, temporary position adjustments are often achieved through rudimentary methods such as shims, resulting in poor stability and easy displacement under traction, affecting guiding accuracy and potentially causing conductors to become tangled or worn. Therefore, there is an urgent need in this field for a universal conductor rack that can flexibly and quickly adjust the guiding position and height while effectively protecting the surface of the conductors. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a conductor frame for cable production, which is achieved by the following specific technical means:
[0005] A conductor frame for cable production includes a horizontal plate, with vertical plates fixedly connected to both ends of the horizontal plate. An mounting plate is installed between two vertical plates, and a slide block is mounted on the mounting plate. A pulley is rotatably mounted on the top of the slide block. Each vertical plate has several rectangular slots evenly spaced on its side. Both ends of the mounting plate are inserted into these rectangular slots. An opening is formed on the surface of the slide block, through which the slide block is fitted onto the mounting plate. A stop plate is slidably mounted within the opening. The upper surface of the stop plate and the bottom surface of the mounting plate are in close contact and both have a rough surface design. A threaded rod is installed at the bottom of the slide block to drive the displacement of the stop plate.
[0006] Furthermore, the rectangular grooves are distributed along the height direction of the vertical plate, and each rectangular groove has a circular hole on its inner wall.
[0007] Furthermore, threaded holes are provided at both ends of the mounting plate, and a screw is screwed into each threaded hole, with each screw passing through a circular hole.
[0008] Furthermore, a ring is fixedly connected to the middle of the bottom end of the stop plate, and an annular groove is formed on the inner wall of the ring.
[0009] Furthermore, the threaded rod passes through the through-hole and is threadedly connected to the slide block. A round block is fixedly sleeved at the top of the threaded rod, and the round block is located in the annular groove. A handwheel is fixedly installed at the bottom of the threaded rod.
[0010] Furthermore, the stop plate is slidably installed inside the opening, with the outer edge of the stop plate fitting against the inner wall of the opening, and mounting holes are provided on the upper surface of the horizontal plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The slide block is fitted onto the mounting plate through the through-hole and can slide freely along its length, realizing the adjustment of the horizontal position of the pulley. This allows a single mounting plate to meet the guiding needs of multiple wires with different spacings at the same height. By setting multiple rectangular slots distributed along the height direction on the vertical plate, the mounting plate can be installed at different heights, thereby quickly adjusting the elevation of the entire guide plane and easily adapting to the guiding height requirements of different production lines or different process stages.
[0013] 2. By rotating the handwheel to drive the threaded rod, the stop plate is pushed so that its rough surface fits tightly against the rough surface of the mounting plate. The huge friction between the planes locks the slide block, and the locking force is large and uniform, which prevents the slide block from moving under the traction force of the wire and ensures the long-term stability of the guide position. The wire is guided by passing around the rotating pulley, which transforms the sliding friction into the rolling friction of the pulley itself, reducing the resistance during the wire's movement and effectively preventing scratches and wear on the insulation layer or sheath of the wire surface.
[0014] Third, the conductor rack for cable production supports the installation of multiple mounting plates on the same sub-frame (horizontal and vertical plates), and multiple slides can be installed on each mounting plate; users can flexibly configure the guide unit according to the specific number of conductors and layers required for the current cable production, realizing "one rack for multiple uses" and improving the equipment's versatility and space utilization.

[0024] Example:
[0025] As attached Figure 1 To be continued Figure 4 As shown:
[0026] This utility model provides a conductor frame for cable production, including a horizontal plate 1, with vertical plates 2 fixedly connected to both ends of the horizontal plate 1. An installation plate 3 is installed between two vertical plates 2, and a slide block 4 is installed on the installation plate 3. A pulley 41 is rotatably installed on the top of the slide block 4. Several rectangular slots 21 are equally spaced on the side of each vertical plate 2. The two ends of the installation plate 3 are respectively inserted into the rectangular slots 21. An opening 42 is opened on the surface of the slide block 4. The slide block 4 is sleeved on the installation plate 3 through the opening 42. A stop plate 5 is slidably installed in the opening 42. The upper surface of the stop plate 5 and the bottom surface of the installation plate 3 are in close contact and both are designed with a rough surface. A threaded rod 6 for driving the displacement of the stop plate 5 is installed at the bottom of the slide block 4.
[0027] The rectangular grooves 21 are distributed along the height direction of the vertical plate 2, and each rectangular groove 21 has a circular hole 22 on its inner wall.
[0028] Both ends of the mounting plate 3 are provided with threaded holes 31, and each threaded hole 31 is screwed into a screw 32, with each screw 32 passing through a round hole 22.
[0029] A ring 51 is fixedly connected to the middle of the bottom end of the stop plate 5, and an annular groove 52 is provided on the inner wall of the ring 51.
[0030] The threaded rod 6 passes through the through-hole 42 and is threadedly connected to the slide block 4. A round block 61 is fixedly sleeved at the top of the threaded rod 6. The round block 61 is located in the annular groove 52. The size of the round block 61 is adapted to the size of the annular groove 52. A handwheel 62 is fixedly installed at the bottom of the threaded rod 6.
[0031] The stop plate 5 is slidably installed in the opening 42, and the outer edge of the stop plate 5 is in contact with the inner wall of the opening 42. The upper surface of the horizontal plate 1 is provided with a mounting hole 11.
[0032] The working principle of this embodiment:
[0033] Step 1: Place the slide 4 onto the mounting plate 3 through the opening 42 on its surface; the number of slides 4 can be flexibly increased or decreased according to the number of conductors required during cable production. Since the slide block 4 and the mounting plate 3 are fitted together, the slide block 4 can slide freely along the length of the mounting plate 3, thereby adjusting the horizontal position of the slide block 4 and the pulley 41 rotatably mounted at the top, to adapt to the guide requirements of wires with different spacing. After the position of the slide block 4 (and pulley 41) is adjusted to the target position, the handwheel 62 mounted at the bottom of the slide block 4 is rotated: the handwheel 62 drives the threaded rod 6 to rotate synchronously. Since the threaded rod 6 passes through the through-hole 42 and is threadedly connected to the slide block 4, the threaded rod 6 will move upward in the vertical direction. The round block 61 fixedly fitted at the top of the threaded rod 6 will rotate freely in the annular groove 52 on the inner wall of the ring 51 at the bottom of the stop plate 5 (to avoid driving the stop plate 5 to rotate). At the same time, the ring 51 pushes the stop plate 5 to slide upward along the inner wall of the through-hole 42 until the upper surface (rough surface) of the stop plate 5 is tightly attached to the bottom surface (rough surface) of the mounting plate 3. By using the friction between the two rough surfaces, the slide block 4 and the mounting plate 3 are relatively fixed, thus locking the position of the slide block 4 (and the pulley 41).
[0034] Step 2: Based on the conductor height requirements during cable production, select one set of rectangular slots 21 cut along the height direction on the side of the vertical plate 2. Insert both ends of the mounting plate 3 into the corresponding rectangular slots 21 of the two vertical plates 2 (the vertical plates 2 that are fixedly connected to the ends of the horizontal plate 1). Then, pass the screws 32 through the round holes 22 on the inner wall of the rectangular slots 21 and rotate them into the threaded holes 31 cut at both ends of the mounting plate 3 to firmly connect the mounting plate 3 to the vertical plate 2, thus completing the height fixing of the mounting plate 3. If multiple sets of conductors are required, the above operation can be repeated to install multiple mounting plates 3 to meet the needs of multiple specifications of cables. The cable guides the conductors to be guided during the cable production process by passing them around the pulleys 41 at the top of each slide block 4. When the conductors move under the traction of the production process, the pulleys 41 rotate synchronously with the conductors, converting the sliding friction between the conductors and the pulleys 41 into rolling friction, which greatly reduces the wear on the surface of the conductors and ensures the integrity of the conductors during the guiding process. The entire conductor frame can be fixed to the designated position on the cable production line using bolts and other fasteners through the mounting holes 11 on the upper surface of the horizontal plate 1, so as to avoid displacement of the conductor frame during the conductor traction process.
