However, the rotating platform is currently usually positioned by using a buffer with a limit bolt or by using a cylinder locking method. These two positioning methods have poor precision and low efficiency, affecting tire production efficiency and tire quality. Summary of the invention

[0005] Furthermore, the fixing member has a protrusion, the limiting member has a recess, the protrusion is inserted into the recess, and the adjusting member is located between the protrusion and the recess.

[0006] Furthermore, the limiting member is a thin-walled tube, and when the rotating table rotates excessively, the rotating table squeezes the limiting member to deform the limiting member.

[0007] Furthermore, there are multiple limiter assemblies, and limiter assemblies are arranged on two opposite sides of the base.

[0008] Furthermore, the outer edge of the rotating table is provided with driven teeth, and the driving assembly includes a gear, which is meshed with the driven teeth; and a driving member, which drives the gear to rotate.

[0009] According to another aspect of the present invention, a method for positioning a rotating platform of a molding machine is provided. The above-mentioned rotating platform of a molding machine is adopted, and the method for positioning the rotating platform of a molding machine includes a driving component driving the rotating platform to rotate a first preset angle from an initial position to a target position at a first rate; the driving component drives the rotating platform to continue rotating toward the target position at a second rate until the limit structure abuts against the limit piece at the target position and the rotating platform stops rotating, wherein the first rate is greater than the second rate.

[0010] Furthermore, the molding machine rotating platform positioning method also includes an adjustment process before driving the rotating table to rotate from an initial position, and the adjustment process includes adjusting the number of adjustment parts of the limit assembly according to the target rotation angle of the rotating table so that the rotating table rotates to the target rotation angle when the rotating table stops rotating.

[0021] In order to solve the problems of poor precision and low efficiency of the positioning method in the prior art, the present application provides a molding machine rotating platform and a molding machine rotating platform positioning method. Example

[0022] See also Figures 1 to 3 The molding machine rotating platform includes a base 10, a driving assembly 20, a rotating table 30 and a limiting assembly 40. The driving assembly 20 is arranged on the base 10. The rotating table 30 is rotatably connected to the base 10. The rotating table 30 is used to prevent the molding machine from being rotated. The driving assembly 20 is drivingly connected to the rotating table 30 and drives the rotating table 30 to rotate. The rotating table 30 has a limiting structure 50. The limiting assembly 40 includes a fixing member 41, a limiting member 42 and at least one adjusting member 43. The fixing member 41 is connected to the base 10. The number of adjusting members 43 can be adjusted between the fixing member 41 and the limiting member 42. When the rotating table 30 is rotated into place, the limiting structure 50 abuts against the limiting member 42 for limiting cooperation.

[0023] The rotation of the rotating table 30 drives the molding machine to rotate, so that the molding machine can cooperate with the tire unloading bracket at different positions. When rotating, the rotating table 30 is driven by the driving component 20, and the rotation of the rotating table 30 is limited by the limiting component 40. When the limiting structure 50 abuts against the limiting member 42, the rotating table 30 cannot continue to rotate. At this time, the molding machine cooperates with the tire unloading bracket, which is convenient for the molding machine to cooperate with the tire unloading bracket. Compared with the use of variable frequency motors with hard limits and cylinder locking mechanisms to position the rotary chassis, the cylinder locking mechanism does not need to work, saving the cylinder locking mechanism action time. The positioning method of the servo motor with the buffer and the limit bolt to position the rotating platform. The bolts will loosen due to repeated impacts for a long time. At the same time, the mounting screws at the bottom of the buffer and the limit bolt support will also cause a certain displacement due to vibration. Therefore, after a period of use, the position of the limit bolt will change, resulting in the loss of molding drum precision and affecting tire quality. The molding machine is rotated and positioned by rotating the rotating table 30 and cooperating with the limiting assembly 40 and the limiting block. The precision is high, stable and reliable, the precision will not be lost after long-term use, the rotation positioning speed is fast, and the tire production efficiency is improved.

[0024] In the present application, the fixing member 41 has a protrusion, the limiting member 42 has a recess, the protrusion is inserted into the recess, and the adjusting member 43 is located between the protrusion and the recess.

[0025] Specifically, by setting the adjustment member 43, the distance between the fixing member 41 and the limiting member 42 away from one end of the fixing member 41 can be changed, thereby changing the matching position of the limiting member 42 and the limiting block. The limiting position can be adjusted according to actual usage conditions, thereby increasing the flexibility of equipment use.

[0026] In the present application, the limiting member 42 is a thin-walled tube. When the rotating platform 30 rotates past a certain position, the rotating platform 30 squeezes the limiting member 42 to deform the limiting member 42 .

[0027] Since the limiting member 42 is a thin-walled tube, even if the program is out of control and the rotating table 30 hits the limiting assembly 40 at a high speed, the limiting member 42 can be deformed to absorb the impact energy, thereby protecting the safety of the equipment.

[0028] The outer diameter of hot-rolled seamless pipes (i.e. thin-walled pipes) is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipes (i.e. thin-walled pipes) can be up to 6mm, and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipes can be up to 5mm, and the wall thickness is less than 0.25mm.

[0029] In the present application, there are multiple limiter assemblies 40 , and limiter assemblies 40 are disposed on two opposite sides of the base 10 .

[0030] By providing a plurality of stoppers 42 , the rotating platform 30 can stop rotating at the position of each stopper 42 , so that the rotating platform 30 can stay at a plurality of different positions, making it more convenient to adapt to different devices.

[0031] In the present application, the outer edge of the rotating platform 30 is provided with a driven tooth 31 , and the driving assembly 20 includes a gear 21 , which meshes with the driven tooth 31 ; and a driving member 22 , which drives the gear 21 to rotate.

[0032] The rotating platform can be driven to rotate conveniently by meshing the driven teeth 31 with the gear 21. At the same time, the driving assembly 20 can be arranged on one side of the base 10, so that the driving assembly 20 can be easily maintained. Example

[0033] The molding machine rotating platform positioning method includes: the driving component 20 drives the rotating table 30 to rotate from the initial position to the target position by a first preset angle at a first rate, and the driving component 20 drives the rotating table 30 to continue rotating toward the target position at a second rate until the limiting structure 50 abuts against the limiting member 42 at the target position, and the rotating table 30 stops rotating, wherein the first rate is greater than the second rate.

[0034] In order to improve the efficiency of the work, the rotating table 30 should rotate as fast as possible. However, the rotating table 30 rotating at a high speed has a high kinetic energy. In this way, when the limit block collides with the limit assembly 40, it will cause greater damage to the equipment. Therefore, after the rotating table 30 rotates a certain angle, the rotating table 30 is decelerated and the rotating table 30 is rotated at a second speed. The molding machine is rotated and positioned by rotating the turntable and cooperating with the limit block and the limit assembly 40. The precision is high, stable and reliable, the precision will not be lost during long-term use, the rotation positioning speed is fast, and the tire production efficiency is improved. At the same time, the rotation of the rotating table 30 is controlled to reduce the rotation time of the rotating table 30 as much as possible, while reducing the damage caused by the collision between the limit assembly 40 and the limit block.

[0035] In the present application, the molding machine rotating platform positioning method also includes an adjustment process before driving the rotating table 30 to rotate from the initial position, and the adjustment process includes adjusting the number of adjustment parts 43 of the limit assembly 40 according to the target rotation angle of the rotating table 30, so that when the rotating table 30 stops rotating, the rotating table 30 rotates to the target rotation angle.

[0036] The number of adjusting members 43 of the position-limiting assembly 40 is adjusted according to the target rotation angle of the rotating table 30, so that when the rotating table 30 stops rotating, the rotating table 30 rotates to the target rotation angle. When the angle that the rotating table 30 needs to rotate changes, the position-limiting assembly 40 is changed by changing the number of adjusting members 43, so that the angle adjusted by the rotating table 30 is used. In this way, the adjustable range of the rotating table 30 can be increased, the flexibility of the rotation of the rotating table 30 can be increased, and various working conditions can be adapted.

[0037] In the present application, the molding machine rotating platform positioning method further includes rotating the rotating platform 30 to separate the limiting member 42 from the fixing member 41 and replacing the limiting member 42 with a new one when the limiting member 42 is squeezed and deformed.

[0038] Specifically, when the rotating table 30 rotates too far, the limiting member 42 will be damaged. By replacing the limiting member 42, the limiting assembly 40 can continue to maintain a working state without affecting the normal operation of the device.

[0039] In the present application, the first preset angle is 90%-99% of the target rotation angle of the rotating table 30 .

[0040] In order to reduce the rotation time of the turntable as much as possible, the turntable should rotate at the first rate for as long as possible, and sufficient time should be reserved for rotation at the second rate. In actual work, adjustments should be made according to the actual situation. Under the premise of ensuring that the turntable rotates as little as possible, the angle of rotation at the second rate should be reduced.

[0041] In the present application, the molding machine rotating platform positioning method also includes determining the initial position before driving the rotating table 30 to rotate from the initial position, the rotation direction of the rotating table 30 from the initial position to the target position is a first direction, and determining the initial position includes the driving component 20 driving the rotating table 30 to rotate in a second direction opposite to the first direction until the limiting structure 50 abuts against the limiting member 42 at the initial position to limit the position.

[0042] When the limiting structure 50 abuts against the limiting member 42, the rotating table 30 cannot continue to rotate. If the rotating table 30 wants to continue to rotate, the driving component 20 needs to drive the rotating table 30 to rotate in the opposite direction. The initial position is determined by the abutment between the limiting structure 50 and the limiting member 42, which facilitates the initial rotation of the rotating disk and reduces damage to the driving component 20.

[0043] In the present application, the molding machine rotating platform positioning method also includes when the limiting structure 50 abuts against the limiting member 42 at the target position, the controller detects and determines the state of the driving component 20, and when the driving component 20 has no displacement, it indicates that the rotating platform 30 has rotated into place.

[0044] When the limiting structure 50 abuts against the limiting member 42, the rotating platform 30 cannot continue to rotate, and the driving assembly 20 cannot continue to rotate. Therefore, when it is detected that the driving assembly 20 has no displacement, it means that the rotating platform 30 has rotated to the right position.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: 1. The rotation of the rotating table 30 drives the molding machine to rotate, so that the molding machine can cooperate with the tire unloading bracket at different positions. When rotating, the rotating table 30 is driven to rotate by the driving component 20, and the rotation of the rotating table 30 is limited by the limiting component 40. When the limiting structure 50 abuts against the limiting member 42, the rotating table 30 cannot continue to rotate. At this time, the molding machine cooperates with the tire unloading bracket, which is convenient for the molding machine to cooperate with the tire unloading bracket. Compared with the use of variable frequency motors with hard limits and cylinder locking mechanisms to position the rotary chassis, the cylinder locking mechanism does not need to work, saving the cylinder locking mechanism action time. The positioning method of the servo motor with the buffer and the limit bolt to position the rotating platform. The bolts will loosen due to repeated impacts for a long time. At the same time, the mounting screws at the bottom of the buffer and the limit bolt support will also cause a certain displacement due to vibration. Therefore, after a period of use, the position of the limit bolt will change, resulting in the loss of molding drum precision and affecting tire quality. The molding machine is rotated and positioned by rotating the rotating table 30 and cooperating with the limiting assembly 40 and the limiting block. The precision is high, stable and reliable, the precision will not be lost after long-term use, the rotation positioning speed is fast, and the tire production efficiency is improved.

[0046] 2. By setting the adjustment member 43, the distance between the fixing member 41 and the limiting member 42 away from one end of the fixing member 41 can be changed, thereby changing the matching position of the limiting member 42 and the limiting block. The limiting position can be adjusted according to actual usage conditions, thereby increasing the flexibility of equipment use.

[0047] 3. Since the limiter 42 is a thin-walled tube, even if the program is out of control and the rotating table 30 hits the limiter assembly 40 at a high speed, the limiter 42 can be deformed to absorb the impact energy, thereby protecting the safety of the equipment.
