Description

Technical Field

[0001] The utility model relates to a wire-reeling device, in particular to a birdcage-type active wire-releasing device. Background Art

[0002] Steel cord is the most widely developed product among rubber skeleton materials and is also the most difficult to produce among metal products. The International Bureau of Synthetic Fiber Standards defines steel cord in its standards as "a structure consisting of two or more steel cords, or a combination of strands or strands and filaments."

[0003] The steel cord production process mainly includes the following key steps: Pretreatment: Clean the surface of the wire rod to remove oxide scale and impurities, reduce drawing resistance, and ensure the surface quality of the finished product. Large drawing: Initially draw the Φ5.5mm hot-rolled wire to Φ3.15mm or Φ2.4mm. Heat treatment: Heat to austenitize, and then quench in a lead bath to improve the strength and elasticity of the steel wire. Electroplating: Copper plating and zinc plating to protect the surface of the steel wire and improve the adhesion to rubber. Wet drawing: High-speed wire drawing is performed in wet wire drawing to make the steel wire reach the required fineness. Stranding into ropes: Apply strong torsional stress to the ultra-fine wire to form a cord, which is then straightened and sent for inspection. As the main skeleton material of tires, steel cord has the characteristics of high strength, flexural resistance, fatigue resistance, and aging resistance. Every step of its production process is crucial and directly affects the quality and performance of the steel cord.

[0004] During the drawing process, steel cord must first pass through lubricating powder before entering the die for drawing. Currently, during the pay-off process, the steel wire does not have a rotating function. As a result, the steel cord carries relatively little lubricating powder when passing through the lubricating powder. As a result, the surface of the steel cord often suffers from scratches during the subsequent drawing process, seriously affecting its surface quality. Utility Model Content

[0005] The utility model aims to provide a birdcage type active pay-off device, which can rotate the steel cord during the pay-off process, so that the surface of the steel cord is fully covered with lubricating powder, which is convenient for subsequent large-scale pulling.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model provides a birdcage type active wire-paying device, comprising a bracket, a wire-paying seat and a driving device;

[0007] A rotating platform is provided on the base of the bracket, and the driving device is used to drive the rotating platform to rotate horizontally;

[0008] The pay-off seat is a birdcage-shaped structure;

[0009] A bottom plate is detachably fixed to the bottom of the pay-off seat, and the bottom plate is detachably fixed to the rotating table and shares the same axis with the rotating table;

[0010] A winding shaft is vertically fixed in the pay-off seat, the top of the winding shaft is fixed to the top inner wall of the pay-off seat, and the bottom of the winding shaft is detachably fixed to the bottom plate and shares the same axis with the bottom plate;

[0011] The outer frame of the pay-off seat is provided with a line-outlet guide wheel, and the top of the bracket is provided with two pay-off guide wheels;

[0012] An edge guide wheel is provided at the edge position of the top outer wall of the pay-off seat.

[0013] Preferably, an extension shaft is provided in the middle of the lower surface of the rotating platform, and the extension shaft passes through the lower surface of the base of the bracket;

[0014] The driving device is a motor, and the output shaft and the extension shaft of the motor are both provided with pulleys, and the same belt is sleeved on the two pulleys.

[0015] Preferably, an intermediate guide wheel is provided in the middle position of the top outer wall of the pay-off seat, and the two pay-off guide wheels are arranged one above and one below on the top of the bracket, and the intermediate guide wheel is located directly below the two pay-off guide wheels.

[0016] Preferably, a protective cover is connected to the base.

[0017] The utility model discloses a birdcage type active pay-off device, which enables the steel cord to rotate during the pay-off process. When the steel cord passes through the lubricating powder box, the surface of the steel cord is covered with lubricating powder, which effectively ensures the surface quality of the steel cord when it is pulled.

[0021] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example

[0023] like Figure 1As shown, a birdcage-type active pay-off device of this embodiment includes a bracket 1, a pay-off seat 2 and a driving device 3.

[0024] A rotating platform 4 is provided on the base of the bracket 1 , and the driving device 3 is used to drive the rotating platform 4 to rotate horizontally.

[0025] The pay-off seat 2 is a birdcage-shaped structure; a base plate 5 is detachably fixed to the bottom of the pay-off seat 2, and the base plate 5 is detachably fixed to the rotating table 4 and shares the same axis with the rotating table 4; a winding shaft 6 is vertically fixed inside the pay-off seat 2, and the top of the winding shaft 6 is fixed to the top inner wall of the pay-off seat 2, and the bottom of the winding shaft 6 is detachably fixed to the base plate 5 and shares the same axis with the base plate 5.

[0026] In this embodiment, if Figure 2 As shown, an extension shaft 7 is provided in the middle of the lower surface of the rotating platform 4, which passes through the lower surface of the base of the bracket 1. The driving device 3 is a motor, and both the motor output shaft and the extension shaft have pulleys (not shown), and the same belt (not shown) is sleeved on the two pulleys. This arrangement allows the driving device 3 to be located below the base without affecting the payout of the steel cord. Furthermore, the payout is an active payout, preventing the steel cord from being broken due to passive payout.

[0027] A wire-outlet guide wheel 8 is provided on the outer frame of the pay-off seat 2 , and two wire-outlet guide wheels 9 are provided on the top of the bracket 1 .

[0028] An edge guide wheel 10 is provided at the edge of the top outer wall of the pay-off seat 2. In this embodiment, the edge guide wheel 10 is located directly above the appearance guide wheel 8, so as to facilitate guiding the steel cord to the pay-off guide wheel 9 at the top of the bracket 1.

[0029] Furthermore, an intermediate guide wheel 11 is provided in the middle position of the top outer wall of the pay-off seat 2, and the two pay-off guide wheels 9 are arranged one above and one below on the top of the bracket 1, and the intermediate guide wheel 11 is located directly below the two pay-off guide wheels 9, which is convenient for guiding the steel cord and facilitating the rotation of the steel cord.

[0030] In this embodiment, if Figure 3 As shown, a protective cover 12 is connected to the base of the bracket 1 to play a protective role and avoid accidental injury to workers during the process of paying out the steel cord.

[0031] During the process of paying out the steel cord, a box filled with lubricating powder is placed on the external fixed seat, and the external fixed seat is placed in the middle of the bracket 1 and directly above the middle guide wheel 11. The I-shaped wheel to be paid out is sleeved on the pay-off seat 2, and the pay-off seat is fixed on the rotating table 4. The motor is started, the rotating table 4 rotates, and the pay-off seat 2 rotates. The steel cord is pulled in turn after passing through the outlet guide wheel 8, the edge guide wheel 10, the middle guide wheel 11, the box filled with lubricating powder and the two pay-off guide wheels 9. Since the steel cord rotates during the pay-off process, its surface is covered with lubricating powder, which effectively protects its surface during the subsequent pulling process.

[0032] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all within the scope defined by the claims of this application.
