Description

Technical Field

[0001] This application relates to the field of tire blank production, and in particular to an automatic marking device for tire blanks based on a winding machine. Background Technology

[0002] In the field of tire manufacturing technology, the increasing automation and precision in tire production are of great significance for improving production efficiency and ensuring product quality. Especially in the production of engineering tires, the application of equipment such as radial tire winding machines makes the production process more efficient. For example, Chinese Patent Publication No. CN119239021B discloses a double-head synchronous radial tire winding machine. During operation, the X-axis drive assembly, Y-axis drive assembly, and rotary drive assembly on each of the two winding mechanisms work together to simultaneously press the rubber strip onto the rotating tire carcass using the flat pressure rollers on the corresponding winding heads.

[0003] In the tire blank production process, markings such as the centerline provide crucial reference for subsequent inspections or process positioning, and their accuracy directly impacts tire quality and performance. In the standard tire blank production process, the common method for marking centerlines and other markings is to manually draw the lines on the rotating tire blank using a laser marking can, guided by a laser pointer. Hand-held marking paint cans suitable for manual operation are available on the market. Furthermore, throughout the tire production process, the positioning of these markings relies primarily on manual operation and reference to the laser markings, lacking more automated and precise positioning methods.

[0004] However, the existing method of manually marking lines with a handheld paint can while following the laser marking line has significant drawbacks. Because this process is entirely manual, worker skill levels vary, and the laser marking line itself has inherent deviations. These factors combine to cause these deviations to accumulate, leading to inaccuracies in subsequent testing or reference standards, and ultimately failing to meet the high-precision marking requirements of tire production. Summary of the Invention

[0005] To improve the marking accuracy of tire blanks, this application provides an automatic marking device for tire blanks based on a winding machine.

[0006] The automatic tire blank marking device based on a winding machine provided in this application adopts the following technical solution: An automatic tire blank marking device based on a winding machine includes: The fixing part is located at the winding head of the winding machine; The swinging part is rotatably connected to the fixed part, and the rotation axis of the swinging part is parallel to the rotation axis of the tire blank at the winding machine; The marking section is fixedly connected to the swing section and is used to mark lines on the surface of the tire blank; The driving component is used to drive the swinging part to swing up and down in order to adjust the angle of the scribing part; When the tire blank is wound, the fixing part moves to the tire blank along with the winding head of the winding machine; after the tire blank is wound, the swinging part is driven to swing downward by the driving member to adjust the angle of the marking part so that the marking part touches the surface of the tire blank; through the rotation of the tire blank and the marking operation of the marking part, the marking work on the surface of the tire blank is completed.

[0007] By adopting the above technical solution, the marking device achieves automated and precise operation. The fixed part is located at the head of the winding machine, ensuring that the marking device moves synchronously to the tire blank position with the winding head, avoiding manual positioning errors. The swinging part is rotatably connected to the fixed part, and its rotation axis is parallel to the tire blank axis, ensuring consistent angles during the marking process. The drive component controls the swinging part to swing up and down, adjusting the angle of the marking part to precisely contact the tire blank surface, and automatically completing the marking in conjunction with the tire blank's rotation. This design solves the problem of cumulative errors caused by operator skill and laser marking deviations in manual marking, significantly improving marking accuracy and stability. It also adapts to continuous production processes of the winding machine, allowing marking to be completed without interrupting operation.

[0008] Preferably, the driving component is a telescopic cylinder, and the fixing part includes a fixing bracket and a fixing seat. The fixing bracket is vertically installed at the winding head position of the winding machine, and the fixing seat is installed on the top of the fixing bracket. One end of the telescopic cylinder is rotatably connected to the fixing seat, and the other end is rotatably connected to the swinging part. The telescopic cylinder drives the swinging part to swing up and down by telescopic movement.

[0009] By adopting the above technical solution, the telescopic cylinder, as the driving component, provides stable and reliable linear power. Its two ends are rotatably connected to the fixed base and the swinging part, respectively, enabling smooth and controllable up-and-down swinging of the swinging part. The fixed bracket is vertically positioned at the winding head to ensure the overall structural rigidity, and the fixed base serves as the supporting foundation for the cylinder, further enhancing system stability. This structure simplifies the driving mechanism, reduces maintenance costs, and ensures the repeatability of the scribing angle adjustment.

[0010] Preferably, the fixed seat is provided with a rotating shaft and is rotatably connected to the top of the fixed bracket through the rotating shaft. The fixed bracket is provided with an arc-shaped groove that extends about the rotating shaft of the fixed seat. The fixed seat is provided with a slider that is slidably connected to the arc-shaped groove. The fixed seat is provided with a threaded locking member that is threadedly connected to the rotating shaft. The fixed seat is locked by locking the rotating shaft through the threaded locking member.

[0011] By adopting the above technical solution, the fixed seat is connected to the bracket through a rotating shaft and slides with the arc groove through a slider, allowing the fixed seat to flexibly adjust its initial position within a certain angle range, thereby adapting to different specifications of blanks or scribing requirements; the threaded locking part can quickly fix the rotating shaft after adjustment, preventing accidental deviation during operation, enhancing the adaptability and flexibility of the device, and ensuring the accuracy of the scribing reference.

[0012] Preferably, the top of the fixed base is provided with two oppositely arranged connecting parts, and both sides of the cylinder body of the telescopic cylinder are provided with short shafts corresponding to the connecting parts. The telescopic cylinder realizes the up-and-down swing function by rotating the short shafts and the corresponding connecting parts.

[0013] By adopting the above technical solution, the cylinder body is rotatably connected to the connecting part on the fixed seat through the short shaft on both sides, forming a double-support structure, which effectively disperses the radial load when the cylinder is working and reduces wear caused by single-point stress concentration.

[0014] Preferably, the swinging part includes a fixed tube body and a front pressure cap. One end of the fixed tube body is rotatably connected to a fixed base, and the end of the fixed tube body away from the fixed base is open. The marking part is a marking paint can body, which is installed in the fixed tube body. The front pressure cap is located at the opening of the fixed tube body, and the paint outlet of the marking paint can body passes through the front pressure cap.

[0015] By adopting the above technical solution, the fixed tube body serves as the main body of the swinging part, and its interior accommodates the standard marking paint can, enabling rapid replacement and maintenance of the marking medium. The front pressure cap is fixed at the opening of the tube body, protecting the paint can and precisely guiding the paint outlet to ensure a continuous and uniform marking trajectory. This integrated design simplifies the structure of the marking part, reduces consumable costs, and avoids the impact of external interference on the marking quality.

[0016] Preferably, the fixed tube and the telescopic cylinder are placed on opposite sides of the fixed bracket.

[0017] By adopting the above technical solution, the fixed tube and the telescopic cylinder are placed on both sides of the fixed bracket, forming a balanced lever arm structure, which reduces the inertial impact during the swing process; at the same time, the overall spatial layout is optimized, avoiding interference with other components of the winding machine head, and enhancing equipment compatibility and operational stability.

[0018] Preferably, a first connecting shaft is horizontally arranged at the bottom of the fixed tube body, and the first connecting shaft is perpendicular to the axis of the fixed tube body; the fixed tube body is rotatably connected to the fixed seat through the first connecting shaft.

[0019] By adopting the above technical solution, the first connecting shaft is horizontally set at the bottom of the fixed tube and perpendicular to the tube axis, providing a stable and reliable rotation center, ensuring that the swinging part swings along the fixed axis, and avoiding trajectory deviation caused by shaking during the scribing process; this design also simplifies the rotating connection structure and improves mechanical efficiency.

[0020] Preferably, a second connecting shaft is horizontally arranged at the side wall of the fixed tube body, and the second connecting shaft is perpendicular to the axis of the fixed tube body; the end of the second connecting shaft away from the fixed tube body is rotatably connected to the piston rod of the telescopic cylinder to realize the relative rotation function between the fixed tube body and the telescopic cylinder.

[0021] By adopting the above technical solution, the second connecting shaft is horizontally set on the upper side of the fixed tube body and rotatably connected to the cylinder piston rod, which efficiently converts the linear thrust of the cylinder into the angular displacement of the fixed tube body, realizing precise control of the scribing angle; this rotating pair design reduces motion friction and improves response speed and adjustment accuracy.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The device is installed on the winding head, and the center line coincides with the winding head, which can eliminate deviations caused by inconsistencies in the design, installation, and production center lines; 2. By utilizing the precise positioning of the winding head of the wrapping machine, the positioning and spacing of the marked lines can be controlled, avoiding the accumulation of errors caused by human operation deviations; 3. Automated marking reduces manual intervention, lowers human resource costs, and enables precise production of tire blanks. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] The automatic tire blank marking device based on a winding machine provided in this application embodiment refers to... Figure 1 and Figure 2 The automatic marking device includes a fixed part 5, a swinging part 4, a marking part 3, and a driving component 6. The fixed part 5 is located at the winding head of the winding machine 1. The swinging part 4 is rotatably connected to the fixed part 5, and its rotation axis is parallel to the rotation axis of the tire blank 2 at the winding machine 1. The marking part 3 is fixedly connected to the swinging part 4 and is used to mark lines on the surface of the tire blank 2. The driving component 6 drives the swinging part 4 to swing up and down to adjust the angle of the marking part 3, achieving the effect of accurately marking lines on the surface of the tire blank 2 after winding production. The fixed part 5 moves with the winding head of the winding machine 1, utilizing the precise positioning of the winding head in the XY axis direction to ensure the accuracy of the spacing. This allows the automatic marking device to move to the appropriate position, and then the driving component 6 adjusts the angle of the marking part 3 to bring it against the surface of the tire blank 2, cooperating with the rotation of the tire blank 2 to complete the marking, avoiding human error.

[0030] Reference Figure 3 and Figure 4Specifically, the fixing part 5 includes a fixing bracket 51 and a fixing seat 52. The fixing bracket 51 is generally made of metal materials such as steel, which has good strength and stability, and is vertically fixed to the frame position of the winding head of the winding machine 1 by bolts. The fixing bracket 51 can also be made of aluminum alloy, which is lightweight and corrosion-resistant. The fixing seat 52 is located on top of the fixing bracket 51. It can be a block structure, and its material can also be steel or aluminum alloy. The fixing seat 52 is provided with a rotating shaft 522, which can be a metal shaft, and is rotatably connected to the top of the fixing bracket 51 to realize the rotation of the fixing seat 52 relative to the fixing bracket 51. An arc-shaped groove 511 is provided at the fixing bracket 51. The arc-shaped groove 511 extends rotatably around the rotating shaft 522 of the fixing seat 52, and its function is to provide a certain range of limitation for the rotation of the fixing seat 52. A slider 521, which slides into the arc-shaped groove 511, is provided at the fixed seat 52. The slider 521 can be a metal block. By engaging with the arc-shaped groove 511, the fixed seat 52 can flexibly adjust its initial position within a certain angle range to adapt to different specifications of tire blanks 2 or marking requirements. The fixed seat 52 is also provided with a threaded locking element 523, such as a bolt, that is threadedly connected to the rotating shaft 522. The rotating shaft 522 is locked to the fixed bracket 51 by the threaded locking element 523, thereby achieving the purpose of locking the fixed seat 52 and ensuring the stability of the fixed seat 52 during operation.

[0031] The top of the fixed base 52 has two opposing connecting parts 524. The connecting parts 524 can be block structures, installed on the top of the fixed base 52 by welding or integral molding. The driving component 6 is a telescopic cylinder. Both sides of the cylinder body have short shafts 61 corresponding to the connecting parts 524. The short shafts 61 can be metal cylinders. The telescopic cylinder achieves its up-and-down swinging function through the rotatable connection between the short shafts 61 and the corresponding connecting parts 524. The telescopic cylinder can also be replaced by other components capable of telescopic function, such as an electric push rod.

[0032] The swinging part 4 includes a fixed tube body 41 and a front pressure cover 42. The fixed tube body 41 is generally made of metal tubing, such as steel or aluminum tubing, with one end rotatably connected to a fixed base 52 and the other end open away from the fixed base 52. A first connecting shaft 411 is horizontally arranged at the bottom of the fixed tube body 41, which is the rotation shaft of the swinging part 4. The first connecting shaft 411 is perpendicular to the axis of the fixed tube body 41. The first connecting shaft 411 can be a metal shaft. The fixed tube body 41 is rotatably connected to the fixed base 52 through the first connecting shaft 411, allowing the fixed tube body 41 to rotate around the first connecting shaft 411. A second connecting shaft 412 is horizontally arranged at the upper side of the fixed tube body 41. The second connecting shaft 412 is perpendicular to the axis of the fixed tube body 41. The end of the second connecting shaft 412 away from the fixed tube body 41 is rotatably connected to the piston rod of the telescopic cylinder to realize the relative rotation function between the fixed tube body 41 and the telescopic cylinder. The second connecting shaft 412 can also be a metal shaft. The front pressure cap 42 is located at the opening of the fixed tube body 41. It can be a round cap that is fixed to the opening of the fixed tube body 41 by means of threaded connection or snap-fit ​​connection.

[0033] The marking section 3 is a marking paint can, which is installed inside the fixed tube 41. It is composed of a marking paint can and a marking head, and is a product manufactured by a proprietary manufacturer that can be purchased directly. The paint outlet of the marking paint can extends through the front pressure cap 42 to mark lines on the surface of the tire blank 2.

[0034] The fixed tube 41 and the telescopic cylinder are placed on both sides of the fixed bracket 51, forming a balanced lever arm structure, which reduces the inertial impact during the swing process; at the same time, it optimizes the overall spatial layout, avoids interference with other components of the winding machine 1 head, and enhances equipment compatibility and operational stability.

[0035] The implementation principle of this embodiment is as follows: After the tire blank 2 is wound, the fixing part 5 moves to the tire blank 2 along with the winding head of the winding machine 1. At this time, the driving part 6 (telescopic cylinder) starts to work, driving the swinging part 4 (fixed tube 41) to swing up and down through the telescopic movement, adjusting the angle of the marking part 3 (marking paint can) so that the paint outlet of the marking paint can comes into contact with the surface of the tire blank 2. Then, the tire blank 2 rotates, and the marking paint can begins to mark the surface of the tire blank 2, completing the marking work. Throughout the process, the servo motors of the X and Y axes of the winding machine 1 control the lead screw to move left and right, precisely controlling the marking position, avoiding the accumulation of errors caused by manual operation, improving the accuracy and precision of marking, and reducing the use of manpower, thus realizing the automation and precision of tire blank 2 marking production.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
