[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0028] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.
[0029] In order to solve the problem of poor quality of all-steel steel cord laminating in the prior art, the present invention provides a steel cord laminating device, a forming machine and a steel cord laminating method.
[0030] like Figures 1 to 3 The steel cord laminating device shown includes a frame 10, a cord laminating template 20, a swing assembly and a correction assembly. The cord laminating template 20 is located at the front end of the frame 10. The cord laminating template 20 includes a transition template 21 and a conveying template 22. The transition template 21 is magnetic and can absorb and convey the cord on the conveying template 22 to the carcass drum 50 to laminate the cord on the carcass drum 50; the swing assembly is connected to the frame 10 and can drive the cord laminating template 20 to move so as to swing and laminate the cord.
[0031] This embodiment incorporates magnetism on the transition template 21. Thus, during the conveying of the cord, the magnetic force of the transition template 21 attracts the cord from the conveying template 22 to the transition template 21 and conveys it to the fitting position on the transition template 21, achieving reliable transition and fitting of the cord. Furthermore, the speed at which the transition template 21 conveys the cord can be matched to the speed of the carcass drum 50, thereby achieving speed matching between the template and the drum and reducing stretching deformation of the steel cord. This arrangement achieves high-precision automatic fitting of the steel cord, reduces cord stretching, and ensures tire quality.
[0032] It should be noted that the front and rear ends in this embodiment refer to the end away from the starting side of the curtain conveyance as the front end, and the end close to the starting side of the curtain conveyance as the rear end.
[0033] like Figure 2 and Figure 3As shown, the cord fitting template 20 of this embodiment further includes a magnetic member, which can be a magnet or other component. The magnetic member is located at the bottom of the transition template 21, and the transition template 21 is located above the conveying template 22. In this way, when the cord on the conveying template 22 is conveyed to the transition template 21, the cord on the conveying template 22 can be adsorbed to the bottom of the transition template 21 under the magnetic force of the magnetic member. Since the transition template 21 is closer to the carcass drum 50 than the conveying template 22, the cord can be subsequently conveyed forward following the transition template 21 to a position where it waits for fitting with the carcass drum 50. By using the transition template 21 with a magnet for cord fitting, the speed matching of the transition template 21 and the carcass drum 50 can be achieved, thereby reducing the tensile deformation of the steel cord.
[0034] In this embodiment, the transition template 21 is movably arranged relative to the conveying template 22, and the curtain fitting template 20 also includes a first drive component 23. The first drive component 23 is arranged between the transition template 21 and the conveying template 22, and can drive the transition template 21 to move forward and backward relative to the conveying template 22 along the conveying direction of the curtain, thereby realizing the position adjustment of the transition template 21 relative to the conveying template 22, ensuring that the transition template 21 can accurately adsorb the curtain on the conveying template 22.
[0035] In this embodiment, the curtain fabric laminating template 20 further includes a second drive assembly 24. The second drive assembly 24 can be a cylinder or other component as needed. The second drive assembly 24 is disposed between the conveying template 22 and the frame 10 and is driven and connected to the transition template 21 and the conveying template 22 via components such as a double-sided toothed synchronous belt, thereby synchronously driving the rollers of the transition template 21 and the conveying template 22 to rotate, thereby achieving rotation of the transition template 21 and the conveying template 22 to convey the curtain fabric. In this way, the transition template 21 and the conveying template 22 are synchronously driven by the double-sided toothed synchronous belt, resulting in good speed matching performance and reduced curtain fabric stretching. Of course, the second drive assembly 24 can also independently drive the rotation of one of the transition template 21 and the conveying template 22, or multiple second drive assemblies 24 can be provided to drive the transition template 21 and the conveying template 22 respectively. It should be noted that the driving of the transition template 21 and the conveying template 22 to rotate mentioned here refers to the driving of the transition template 21 and the conveying template 22 to rotate. Specifically, the transition template 21 and the conveying template 22 include a drive-connected roller and a conveying component. The conveying component can be a transmission belt, etc. The curtain is placed on the conveying component. The rotation of the roller can drive the conveying component to rotate through friction, etc., thereby conveying the curtain thereon.
[0036] The cord fitting template 20 of this embodiment also includes a control switch 25, which is arranged on the front end side of the cord fitting template 20. The control switch 25 is electrically connected to the swing assembly or a component that drives the swing assembly. The control switch 25 is used to control the distance between the cord fitting template 20 and the carcass drum 50. That is, when the transition template 21 approaches the carcass drum 50 to a predetermined distance, the control switch 25 is triggered, and the servo drive device controls the swing assembly to stop swinging, thereby protecting the cord fitting template 20 and preventing the transition from colliding with the carcass drum 50.
[0037] like Figure 1 As shown, in this embodiment, the swing assembly includes a swing frame 30 and a correction assembly. The swing frame 30 is connected to the frame 10 and the curtain fitting template 20, and can drive the curtain fitting template 20 to move to swing and fit the curtain. The swing frame 30 is electrically connected to the control switch 25; the correction assembly is connected to the frame 10, and can detect the offset of the curtain when the curtain is conveyed, and perform swing correction on the curtain.
[0038] Specifically, the correction component includes a correction electric cylinder component 41, a correction lens component 42 and a correction light source component 43. Among them, the correction electric cylinder component 41 is connected to the frame 10, and is connected to the curtain fitting template 20 and the swing frame 30 to control the correction movement of the curtain fitting template 20 on the swing frame 30. The correction lens component 42 is facing the curtain to detect the offset of the curtain when the curtain is conveyed; the correction light source component 43 is connected to the frame 10, and detects the offset of the curtain together with the correction lens component 42. The correction lens component 42 of this embodiment adopts a CCD (charge coupled device) lens. The CCD lens detects the offset of the curtain and cooperates with the correction electric cylinder component 41 to correct the curtain, with good correction effect and high correction accuracy.
[0039] In this embodiment, the curtain fabric fitting template 20 further includes an encoder assembly 26 , which is mounted on the active roller of the conveying template 22 . The encoder assembly 26 measures the curtain fabric length alone or together with the correction lens assembly 42 , with high measurement accuracy.
[0040] In addition to using the encoder assembly 26, a length measuring switch can also be used. The length measuring switch is set on the conveying template 22 and can also measure the length of the curtain.
[0041] like Figure 4 As shown, this embodiment also provides a steel cord laminating method, using the above-mentioned steel cord laminating device, the steel cord laminating method includes the following steps:
[0042] The first driving assembly 23 drives the transition template 21 to extend to the working position;
[0043] The swing assembly's swing frame 30 drives the fabric laminating template 20 to swing back to its return position. The cut-to-length fabric is then transferred to the conveyor template 22, where it awaits lamination. During this process, the swing assembly corrects the fabric's deflection. The correction light source assembly 43 and correction lens assembly 42 of the swing assembly detect the fabric's deflection. The correction cylinder assembly 41 of the correction assembly drives the fabric laminating template 20 left and right on the swing frame 30 to correct the deflection and ensure the fabric is centered.
[0044] The second drive assembly 24 synchronously drives the conveying template 22 and the transition template 21 through a double-sided toothed synchronous belt. The conveying template 22 conveys the curtain to the transition template 21. During this process, the encoder assembly 26 and the correction lens assembly 42 jointly measure the length of the curtain.
[0045] The transition template 21 magnetically attracts the curtain fabric from the conveying template 22 to the transition template 21 and conveys it forward to the laminating position to wait;
[0046] The swing frame 30 drives the curtain fabric laminating template 20 to swing downward to the laminating position, ready for laminating;
[0047] As the carcass drum 50 rotates, the cord laminating template 20 matches the carcass drum 50 at a speed that matches the carcass drum 50. The template 20 also applies downward pressure, ensuring the cord adheres to the composite components of the carcass drum 50. This prevents the cord from detaching during rotation and ensures a secure laminating effect. During this process, a control switch 25 protects the movement of the transition template 21. If the transition template 21 rotates too far and strikes the drum surface, the control switch 25 is triggered, causing the transition template 21 to stop rotating, protecting both the transition template 21 and the drum plate of the carcass drum 50.
[0048] After laminating, the transition template 21 returns and the curtain is sewed.
[0049] By using the above-mentioned steel cord laminating method in conjunction with a steel cord laminating device, high-precision automatic laminating of the steel cord can be achieved, thereby reducing cord stretching and ensuring tire quality.
[0050] It should be noted that, in the above embodiments, a plurality refers to at least two.
[0051] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0052] 1. Solve the problem of poor quality of all-steel steel cord lamination in the existing technology;
[0053] 2. Achieve speed matching between the template and the drum to reduce the tensile deformation of the steel cord;
[0054] 3. The double-sided toothed synchronous belt is used to achieve synchronous drive of the transition template and the conveying template, which has good speed matching performance and reduces the stretching of the curtain fabric;
[0055] 4. The control switch protects the cord laminating template to prevent excessive collision with the carcass drum;
[0056] 5. The CCD lens detects the deviation of the curtain fabric and cooperates with the correction electric cylinder assembly to correct the curtain fabric, with good correction effect and high correction accuracy;
[0057] 6. The encoder assembly and the correction lens assembly jointly measure the length of the curtain with high measurement accuracy.
