Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and specifically to a traction device for cable processing. Background Technology

[0002] In the modern cable processing industry, traction devices are indispensable key equipment in the production process, and their performance directly affects the quality and efficiency of cable processing. Currently, most common cable processing traction devices on the market adopt a conveying method with two rows of straight-lined pressure rollers. The cable is clamped and pulled by the two rows of parallel pressure rollers. Due to the simple contact method between the cable and the pressure rollers and the small contact wrap angle, the traction force that the device can provide is limited. When pulling thicker cables or cables with high surface friction, slippage is likely to occur, making stable conveying impossible. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a traction device for cable processing, which improves the traction force when conveying cables.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a traction device for cable processing, comprising:

[0005] Two traction units are symmetrically slidably mounted on the base;

[0006] A spacing adjustment mechanism, mounted on the base, is used to adjust the spacing between the two traction units;

[0007] The guide unit is fixed on the base, and the cable passes through the guide unit and between the two traction units;

[0008] The traction unit includes a housing and multiple pressure rollers rotatably mounted in the housing. Belts are wound around the multiple pressure rollers, which are arranged in an "S" shape. Corresponding pressure rollers in two traction units cooperate to clamp the cable between two belts.

[0009] Preferably, the traction unit further includes a drive wheel and a driven wheel rotatably mounted inside the housing, and the belt is wound around the drive wheel, the driven wheel and a plurality of pressure rollers.

[0010] Preferably, a drive shaft is rotatably mounted on the base, and the drive shaft drives the drive wheels of the two traction units to rotate simultaneously through a transmission mechanism.

[0011] Preferably, the transmission mechanism includes:

[0012] The two first bevel gears are respectively fixed on the axle of the driving wheel in the two traction units;

[0013] Two rotating sleeves are rotatably mounted on two outer shells via bearing seats, and the rotating sleeves are slidably sleeved on the drive shaft via splines;

[0014] Two second bevel gears are fixed on two rotating sleeves and mesh with two first bevel gears respectively.

[0015] Preferably, two positioning frames are slidably mounted on the outer shell, and the multiple pressure rollers in the traction unit are divided into two groups. The two groups of pressure rollers are rotatably mounted on the two positioning frames respectively. Two adjusting rods are rotatably mounted on the outer shell, and the two adjusting rods are threadedly engaged with the two positioning frames respectively.

[0016] Preferably, the two sets of pressure rollers are distributed in a staggered manner.

[0017] Preferably, the spacing adjustment mechanism includes:

[0018] The lead screw is rotatably mounted on the base;

[0019] Hinged seat, threaded onto the lead screw;

[0020] Two connecting rods are respectively hinged to two housings, with the end of the connecting rod away from the housing hinged to a hinge seat.

[0021] Preferably, a slide rail is fixed on the base, and a slider is fixed to the bottom of the housing and slidably mounted on the slide rail.

[0022] Preferably, the traction unit further includes a plurality of guide wheels rotatably mounted inside the housing. The guide wheels are located between two adjacent pressure wheels and are used for belt reversal, so that the belt wraps around the same side of the two adjacent pressure wheels.

[0023] Preferably, there are two guide units, located at both ends of the base respectively; each guide unit includes a bracket and a guide cylinder fixed on the bracket, and a damping sleeve is provided inside the guide cylinder, through which the cable passes.

[0024] The beneficial effects of this utility model are as follows:

[0025] The traction unit designed in this utility model includes multiple pressure rollers, which are arranged in an "S" shape. When two traction units approach each other, the multiple pressure rollers press the belt onto the cable, squeezing the cable into an S shape. This forms multiple contact segments, increasing the contact wrap angle and positive pressure between the cable and the pressure rollers. Compared with the traditional two-row straight-line arranged pressure roller conveying form, it has the advantage of greater traction force.

[0026] This utility model is equipped with a lead screw and connecting rod structure. The rotatable lead screw drives the hinge seat to move, and the two connecting rods drive the outer shell to slide on the slide rail, thereby changing the distance between the two traction units. This allows the utility model to be adapted to the conveying of cables of various diameters, and at the same time, it is easy to adjust the friction between the belt and the cable.

[0027] In the traction unit designed in this utility model, the pressure rollers are divided into two groups, and their positions can be moved by two adjusting rods, thereby changing the degree of misalignment of the "S"-shaped distribution of the pressure rollers, adjusting the contact wrap angle between the cable and the pressure rollers, and avoiding damage to the cable.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] like Figures 1 to 6 As shown, Embodiment 1 of this utility model provides a traction device for cable processing, including a base 1, two traction units, a spacing adjustment mechanism, and a guide unit. Four slide rails 17 are fixed on the base 1, symmetrically distributed in pairs on the base 1. The slide rails 17 extend along the width direction of the base 1. The two traction units are symmetrically arranged on the base 1, and each traction unit has a slider 18 fixed to the bottom of its outer shell 2, which is slidably mounted on the slide rail 17. The four slide rails 17 allow the two traction units to slide smoothly relative to each other on the base 1 along the slide rails 17.

[0040] by Figure 4 When viewed from the reference point, it can be seen that four pressure rollers 3 are rotatably mounted inside the outer casing 2 of the traction unit. These four pressure rollers 3 are arranged alternately up and down inside the outer casing 2, forming a curved path similar to an "S". A driving wheel 5, a driven wheel 6, and multiple guide rollers 19 are also rotatably mounted inside the outer casing 2. The belt 4 is wound around the driving wheel 5, driven wheel 6, multiple guide rollers 19, and multiple pressure rollers 3, forming a closed transmission ring. Each guide roller 19 is located between two adjacent pressure rollers 3. When the belt 4 passes between two adjacent pressure rollers 3, the guide roller 19 guides the belt 4 to change direction, ensuring that the belt 4 is wound on the same side of adjacent pressure rollers 3. This allows each pressure roller 3 to act on the belt 4, pressing the belt 4 against the cable. It should be noted that, generally, belt 4 mechanisms have a tensioning device, but this utility model does not improve the tensioning device, so it is not shown in the accompanying drawings. The tensioning device can use existing technology and is set inside the outer casing 2 to tension the belt 4.

[0041] like Figure 3 As shown, when the left and right traction units approach each other, the corresponding pressure rollers 3 in the two traction units cooperate, causing the two belts 4 to clamp the cable from the upper and lower sides. Since the pressure rollers 3 are distributed in an "S" shape, the cable is squeezed into an S shape, forming multiple contact segments, which significantly increases the contact wrap angle and positive pressure between the cable and the pressure rollers 3. Compared with the traditional two rows of straight-line arranged pressure rollers 3 conveying form, it has the advantage of greater traction force.

[0042] To restrict the position of the cable, guide units are fixed at both the front and rear ends of the base 1. Each guide unit includes a bracket fixed to the base 1 and a guide cylinder 20 fixed to the bracket. A damping sleeve 21 is fixedly installed inside the guide cylinder 20. The cable passes through the damping sleeve 21, which provides a certain damping effect on the cable, keeping it stable before entering the traction unit and facilitating accurate clamping of the cable by the traction unit.

[0043] The base 1 is equipped with a spacing adjustment mechanism, which can adjust the spacing between the two traction units, thereby allowing the two belts 4 to clamp or loosen the cable. Figure 4 As shown, the spacing adjustment mechanism includes a lead screw 14, a hinge seat 15, and two connecting rods 16. The lead screw 14 is rotatably mounted on the base 1 via two bearing seats, and the hinge seat 15 is threaded onto the lead screw 14. When the lead screw 14 is rotated, the hinge seat 15 moves axially along the lead screw 14. The two connecting rods 16 are hinged to the two outer shells 2 respectively, with the end of the connecting rod 16 away from the outer shell 2 hinged to the hinge seat 15. Therefore, the movement of the hinge seat 15 causes the sliders 18 at the bottom of the two outer shells 2 to slide on the slide rail 17 via the connecting rods 16, thereby changing the spacing between the two traction units. This design allows the present invention to adapt to the conveying of cables of various diameters, while facilitating the adjustment of the friction between the belt 4 and the cable to meet different processing requirements.

[0044] Example 2:

[0045] Based on Embodiment 1, this embodiment further designs a drive mechanism with two belts 4. Combined with... Figure 4 and Figure 5 As can be seen from the contents, a drive shaft 7 is rotatably mounted on the base 1 via two bearing seats, and the drive shaft 7 is perpendicular to the lead screw 14. A motor 22 for driving the drive shaft 7 to rotate is fixed on the base 1. The drive shaft 7 of this utility model can simultaneously drive the drive wheel 5 in two traction units to rotate through a transmission mechanism, so as to realize the synchronous drive of the two traction units and ensure the stability and consistency of cable traction.

[0046] like Figure 5As shown, the transmission mechanism includes two first bevel gears 8, two rotating sleeves 10, and two second bevel gears 11. The axle 9 of the drive wheel 5 extends below the housing 2. The two first bevel gears 8 are respectively fixed on the axle 9 of the drive wheel 5 in the two traction units and rotate together with the axle 9 of the drive wheel 5. The two rotating sleeves 10 are rotatably mounted on the bottom of the two housings 2 via bearing seats. Both rotating sleeves 10 are slidably sleeved on the drive shaft 7 via splines, meaning that the rotating sleeves 10 can slide axially on the drive shaft 7 and rotate together with the drive shaft 7. The two second bevel gears 11 are respectively fixed on the two rotating sleeves 10 and mesh with the two first bevel gears 8 respectively. When the drive shaft 7 rotates, it drives the rotating sleeves 10 to rotate, and then drives the axle 9 of the drive wheel 5 to rotate through the meshing of the second bevel gears 11 and the first bevel gears 8, thereby causing the drive wheel 5 to rotate and driving the belt 4 and the pressure roller 3 to move.

[0047] With the above configuration, the drive shaft 7 can simultaneously drive the drive wheels 5 of the two traction units, ensuring synchronous movement of the two traction units and avoiding problems such as uneven cable stress caused by asynchrony. Meanwhile, the rotating sleeve 10 is connected to the drive shaft 7 via a spline, allowing the rotating sleeve 10 to slide within a certain axial range to adapt to positional changes during the adjustment of the distance between the two traction units, ensuring the stability and reliability of the transmission.

[0048] Example 3:

[0049] like Figure 4 As shown, based on Embodiments 1 and 2, this invention features two slidably mounted positioning frames 12 within the outer casing 2 of the traction unit. Four pressure rollers 3 are divided into two groups, each group rotatably mounted on one of the positioning frames 12. Two adjusting rods 13 are rotatably mounted on the outer casing 2, with handles fixed to their ends. The portions of the two adjusting rods 13 located within the outer casing 2 are threaded, and these two adjusting rods 13 are threadedly engaged with the two positioning frames 12 respectively.

[0050] When the adjusting rod 13 is rotated, the positioning frame 12 slides within the housing 2 along the axial direction of the adjusting rod 13 due to the threaded engagement between the adjusting rod 13 and the positioning frame 12, thereby moving the pressure rollers 3 mounted on it. The two sets of pressure rollers 3 are distributed in a cross pattern, and the degree of misalignment of the overall "S"-shaped distribution can be adjusted by the adjusting rod 13. For example, when it is necessary to adjust the contact angle between the cable and the pressure rollers 3, rotating the adjusting rod 13 moves the two sets of pressure rollers 3 closer or further apart, changing the curvature of the "S" shape, thereby adjusting the contact angle and preventing damage to the cable due to an excessively large contact angle. It can also be adjusted adaptively according to different cable materials and diameters.

[0051] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
