Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a guiding and conveying device for cable production. Background Art

[0002] A cable is a device for transmitting electric energy or signals. It is usually a cable similar to a rope formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a central wire. The whole is wrapped with a highly insulating covering layer. The cable has the characteristics of being electrically conductive inside and insulated outside.

[0003] There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. During the production process of cables, since the overall length of the cable is relatively long, it is necessary to guide the cable during the production and transmission process. These mechanical components and equipment for guiding the cable during the transmission process are collectively referred to as cable guiding devices.

[0004] However, in the prior art, the cable is supported and rolled during transmission through components such as transmission rollers. However, these components such as transmission rollers are cylindrical components, resulting in a risk of position deviation of the cable during transmission. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the cable is supported and rolled during transmission through components such as transmission rollers. However, these components such as transmission rollers are cylindrical components, resulting in a risk of position deviation of the cable during transmission.

[0006] To solve the above technical problem, the technical solution of the utility model is as follows:

[0007] A guiding and conveying device for cable production includes a cable. A plurality of adjustable support frames connected in pairs are installed on the outer side of the cable. Two adjustable support frames connected in pairs are symmetrically arranged up and down, and the ends are mutually attached. A guiding roller is rotatably installed between the two ends of the adjustable support frame. Two symmetrically distributed connecting rings are slidably installed on the outer side of the guiding roller. Limit blocks are fixed at both ends of the connecting ring. Electric telescopic rods are fixed on the inner sides of both ends of the adjustable support frame. The movable end of the electric telescopic rod is fixedly connected with the limit block. One end of the limit block is attached to the outer side of the cable, and this end is a smooth arc surface.

[0008] Preferably, two adjacent limit blocks up and down are symmetric with each other. An installation groove is provided at the end of the limit block attached to the cable, and a limit circular block is installed inside the installation groove.

[0009] Preferably, a positioning short shaft is fixed to the end of the limiting circular block that fits the surface of the installation groove, and the positioning short shaft is rotationally inserted into the limiting block.

[0010] Preferably, a plurality of adjusting connecting rods distributed in a circular array are fixed to the other end of the limiting circular block, and a plurality of guiding insertion grooves are distributed in a circular array on the outer surface of the limiting circular block.

[0011] Preferably, the adjusting connecting rod at the end of the limiting circular block is slidably inserted into the guiding insertion groove on the outer surface of another limiting circular block that coincides with the axis of this limiting circular block.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. After the electric telescopic rod is powered on and started, it pushes the limiting block to move, so that the limiting block drives the connecting ring to slide outside the guiding roller. The cable is clamped by rolling with two limiting circular blocks with coincident axes installed between the limiting blocks located on both sides of the cable during movement and the two adjacent upper and lower limiting blocks, ensuring that the cable is transmitted straight and will not move sideways, and avoiding damage to the cable during the production process due to position deviation.

[0014] 2. By providing guiding insertion grooves on the outer surface of the limiting circular block, an adjusting connecting rod is fixed to the end of the limiting circular block and the adjusting connecting rod is slidably inserted into the guiding insertion groove on the outer surface of another limiting circular block. When the distance between the two limiting circular blocks increases but does not exceed the total length of the two adjusting connecting rods, the adjusting connecting rod ensures that the side of the cable is always restricted, avoiding the cable from moving sideways, and can position the position and guide the transmission of cables with different diameters.

[0020] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation on the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in Figure 1 and Figure 2 , a plurality of adjustable support frames 1 connected in pairs are installed on the outer side of the cable 3. The two adjustable support frames 1 connected in pairs are symmetrically arranged up and down in position and the ends are mutually attached. A guide roller 2 is rotatably installed between the two ends of the adjustable support frame 1. Two symmetrically distributed connecting rings 6 are slidably installed on the outer side of the guide roller 2. Limiting blocks 5 are fixed at both ends of the connecting ring 6. Electric telescopic rods 4 are fixed on the inner sides of both ends of the adjustable support frame 1. The movable end of the electric telescopic rod 4 is fixedly connected to the limiting block 5. One end of the limiting block 5 is attached to the outer side of the cable 3 and this end is a smooth arc surface. The cable 3 is clamped, positioned and guided by the limiting blocks 5 on both sides of the cable 3, ensuring that the cable 3 will not be displaced during transmission.

[0022] As a preferred technical solution of this embodiment, as shown in Figure 3 and Figure 4 , the upper and lower adjacent limiting blocks 5 are symmetrical with each other. An installation groove 7 is provided at the end of the limiting block 5 that is attached to the cable 3. A limiting circular block 8 is installed inside the installation groove 7. A positioning short shaft 11 is fixed at the end of the limiting circular block 8 that is attached to the surface of the installation groove 7. The positioning short shaft 11 is rotatably inserted into the limiting block 5. A limiting circular block 8 is installed inside the installation groove 7, and the limiting circular block 8 is rotatably connected to the limiting block 5 through the positioning short shaft 11. When friction occurs between the cable 3 and the limiting circular block 8 during the transmission of the cable 3, the limiting circular block 8 can rotate, reducing the frictional resistance between the cable 3 and the limiting block 5 and preventing the cable 3 from being damaged due to excessive frictional force.

[0023] In this embodiment, a plurality of adjusting connecting rods 9 distributed in a circular array are fixed at the other end of the limiting circular block 8. A plurality of guiding insertion grooves 10 are distributed in a circular array on the outer surface of the limiting circular block 8. The adjusting connecting rods 9 at the end of the limiting circular block 8 are slidably inserted into the guiding insertion grooves 10 on the outer surface of another limiting circular block 8 that coincides with the axis of this limiting circular block 8. The two limiting circular blocks 8 with coincident axes are connected by the adjusting connecting rods 9. When the distance between the two limiting circular blocks 8 increases but does not exceed the total length of the two adjusting connecting rods 9, the adjusting connecting rods 9 ensure that the side of the cable 3 is always restricted, preventing the cable 3 from moving sideways.

[0024] Working principle: First, pass the cable through between two adjacent guiding rollers 2 on the upper and lower layers of the cable 3. Subsequently, connect the power supply of the electric telescopic rod 4 and start it. After the electric telescopic rod 4 starts, it pushes the limit block 5 to move, causing the limit block 5 to drive the connecting ring 6 to slide on the outside of the guiding roller 2. Use the limit blocks 5 that are moving and located on both sides of the cable 3 to position the cable 3, and use two limit circular blocks 8 with coincident axes installed between two adjacent upper and lower limit blocks 5 to roll and clamp the cable 3, so that the cable 3 is located in the middle of the guiding roller 2. Subsequently, start the cable production equipment to process the cable. When the cable is transmitted under the drive of the production equipment, the limit circular block 8 is located on the side of the cable 3 to limit the position of the cable 3, ensuring that the cable 3 is transmitted straight and will not move sideways, avoiding damage to the cable during the production process due to position deviation.

[0025] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
