Description

Technical Field

[0001] This utility model relates to the field of tire steel cord fabric calendering production technology, specifically a magnetic steel wire calendering warping roller and warping machine. Background Technology

[0002] Steel wire calendering is a crucial semi-finished component production process in tire manufacturing, mainly producing belt layer steel wire cord fabric and carcass steel wire cord fabric. Quality requirements include ensuring uniform steel wire density and eliminating uneven steel wire arrangement. Before rubber coating on the calender, there is a set of grooved steel wire warping rollers. The steel wires are evenly arranged on the grooves of the warping rollers (one steel wire per groove) to ensure that the density and arrangement of the steel wires after rubber coating meet the technical requirements. The drawback is that when the steel wire tension is abnormal, skipped wires can occur, resulting in uneven arrangement and scrapped tires. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to provide a magnetic steel wire calendering and warping roller and a warping machine, in which steel wires are placed in grooves on the outer cylinder. The uniformly distributed grooves can arrange the steel wires evenly. The high-strength magnets attract the steel wires and prevent them from jumping out of the grooves. This would prevent abnormal tension or lack of tension from causing uneven wire arrangement and batch quality accidents.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0012] As a preferred embodiment, two connecting blocks are fixedly installed on the inner walls of opposite sides of the mounting frame, and a limit roller is rotatably connected between the two opposite connecting blocks.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-6 As shown, a magnetic wire rolling warping roller includes a magnetic warping roller mechanism 12. The magnetic warping roller mechanism 12 includes a central rod 2, a high-strength magnet 21, a limiting ring 22, a rotating bearing 23, and an outer cylinder 24. The high-strength magnet 21 is sleeved on the outside of the central rod 2. The limiting rings 22 are fixedly installed at opposite ends of the central rod 2. The rotating bearings 23 are fixedly installed inside the limiting rings 22. The outer cylinder 24 is sleeved on the outside of the high-strength magnet 21. The inner wall of the outer cylinder 24 is in contact with the rotating bearings 23, and the outer cylinder 24 is rotatably connected to the limiting rings 22. The outer cylinder 24 has several grooves 25 that are evenly distributed on the outside. The outer cylinder 24 is made entirely of austenitic stainless steel.

[0025] When manufacturing tire cord fabric, several strands of steel wire are evenly distributed and laid out in the groove 25 to separate the steel wires and avoid uneven arrangement caused by the steel wires coming together. The groove 25 also shortens the distance between the steel wire and the high-strength magnet 21, allowing the steel wire to be better attracted and preventing the steel wire from jumping. The movement of the steel wire in the groove 25 will drive the outer cylinder 24 to rotate. The outer cylinder 24, made of austenitic stainless steel, will not be attracted by the high-strength magnet 21, thus enabling it to rotate. The two rotating bearings 23 make the rotation of the outer cylinder 24 smoother.

[0026] This invention places steel wires in grooves 25 on the outer cylinder 24. The evenly distributed grooves 25 ensure uniform steel wire arrangement. The high-strength magnet 21 holds the steel wires in place, preventing batch quality accidents caused by steel wires jumping out of the grooves 25, resulting in abnormal or no tension in the steel wires and uneven arrangement.

[0027] Example 2

[0028] like Figures 1-3 The magnetic wire warping and straightening machine shown includes: a mounting frame 1; magnetic warping roller mechanisms 12 are provided on both sides of the mounting frame 1, and support feet 11 are fixedly installed at the bottom of the mounting frame 1; a mounting plate 3 is provided on the top of the mounting frame 1, and a tensioning assembly is provided at the bottom of the mounting plate 3. The tensioning assembly further includes: a mounting base 31, an electric push rod 32, a moving block 33, and a tensioning roller 34. Guide rails 35 are fixedly installed on the inner walls of opposite sides of the mounting frame 1, two moving blocks 33 are located inside the guide rails 35, and two electric push rods 32 extend into the two guide rails 35 respectively.

[0029] By controlling the retraction of the two electric push rods 32, the output ends of the two electric push rods 32 push the moving block 33 to move on the guide rail 35. The guide rail 35 guides the moving block 33. When the two moving blocks 33 move, they will drive the tension roller 34 to move upward. Since the steel wire is placed above the tension roller 34, the tension roller 34 lifts the steel wire upward. By controlling the two electric push rods 32 to push out, the steel wire is lowered. The tension of the steel wire is adjusted in conjunction with the two limit rollers 41.

[0030] The mounting frame 1 has two mounting brackets 26 fixedly installed on opposite sides. Each mounting bracket 26 has a retainer 27 fixedly installed on its top. The two retainers 27 have mounting rods 28 inside. The mounting frame 1 has two connecting blocks 4 fixedly installed on opposite inner walls. The two connecting blocks 4 are rotatably connected to a limit roller 41.

[0031] The rotating shafts at both ends of the magnetic warping roller mechanism 12 are connected to the opposite ends of the two mounting rods 28, so that the magnetic warping roller mechanism 12 can rotate inside the two retainers 27. The movement trajectory of the steel wire can be restricted by the limiting rollers 41. The two limiting rollers 41 press the steel wire down, and without affecting the movement of the steel wire, the steel wire is pressed down so that a wrap angle is formed between the steel wire and the outer cylinder 24, which effectively prevents the steel wire from moving out of the groove 25.

[0032] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

The descriptions of the above embodiments are only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
