Description

Technical Field

[0001] The invention relates to a two-step double-station integrated molding machine for an all-steel engineering tire, belonging to the technical field of tire processing equipment. Background Art

[0002] The domestic forming machines for all-steel tires are mainly two-drum one-step forming machines, three-drum one-step forming machines, four-drum one-step forming machines and two-step forming machines. The one-step forming machine has the problem that after the tire is formed, there is a gap at the drum shoulder, which affects the tire quality and cannot be solved. This is mainly because the wire ring of the one-step forming drum relies on the expansion of the lock block to position, and the drum shoulder cannot be compacted after the capsule is expanded. The structure of the forming drum determines that this problem is difficult to solve. The ordinary two-step forming machine has low forming efficiency. The completed tire embryo in one stage needs to be manually installed on the second stage forming drum, especially for medium and large size tires. The tire embryo is heavy, the time cost is high, and manual participation has a certain impact on the quality. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and provide a two-step double-station all-steel engineering tire forming machine that automatically transfers tire blanks from the first stage to the second stage, reduces labor costs, improves efficiency, and enhances tire quality.

[0033] The present invention is a two-step dual-station integrated molding machine for all-steel engineering tires. The carcass drum and the turn-up drum work independently. The carcass tube composite is pasted on the bonding drum and then transferred to the turn-up drum, and the steel ring is buckled onto the side of the turn-up drum after the carcass tube is turned up. After the carcass tube of the one-step molding machine is completed, when the carcass transfer ring clamps the carcass tube, the transfer ring also comes with a steel ring and is sleeved onto the carcass tube, and then transferred to the capsule molding drum to position the steel ring and turn it upside down. The tube of the one-step molding machine will be smaller than the inner diameter of the steel ring, while the carcass tube of the two-step molding machine will be larger than the inner diameter of the steel ring. In this way, after the final molding, the carcass cord tube diameter of the two-step molding machine is larger than that of the one-step molding machine, which means that for tires of the same specification, the expansion amount is small, and the density of the carcass cord is relatively large, that is, the thickness is thick, which can greatly reduce the probability of causing the crown to burst. The steel wire ring of the two-step dual-station integrated molding machine is fixed by drum shoulder positioning, which is rigid positioning. The wire ring is installed on the buckle ring disks on both sides of the reverse drum. When the cord is evenly contracted by the finger-shaped piece to be smaller than the inner diameter of the steel ring, the cylinder drives the buckle ring disk to extend and push the wire ring to the shoulder of the reverse drum. This can fully ensure that there are no gaps and bubbles at the inner mouth of the tire, and the mouth and the rim are all in uniform contact, greatly reducing the probability of air accumulation at the mouth. The one-time method relies on the extension of the tiles inside the capsule drum to position, and relies on the inflation of the capsule to squeeze the bubbles at the shoulder of the drum. There are problems of unsolid pressure and gaps, which affect the quality of the tire. The reverse drum of the two-time method double-station integrated molding machine is a solid rigid structure. The rubber material is tightly attached to the drum. When rolling the mouth and other parts, it can be firmly compacted to reduce bubbles in the mouth and other parts. The one-time molding machine is rolled after inflation. The rolling is supported by the pressure of the gas on the inside, which is bound to cause the problem of unsolid rolling. After the wire ring of the two-step double-station integrated forming machine is wrapped in a finger-shaped capsule and reversed, the rear pressure roller further rolls to drive out bubbles. After the tire sidewall is applied, the rear pressure roller rolls the sub-mouth. This two-time rolling is conducive to the sub-mouth being firm and free of bubbles. At the same time, the two-step double-station integrated forming machine transfers a section of the formed carcass cord tube directly to the second-stage PU drum through the carcass transfer trolley, eliminating manual participation, saving time and cost. The second-stage PU drum consists of two sets, which are horizontally distributed at 180 degrees. The main machine can rotate as a whole. While the 1# main machine is winding, the 2# main machine can apply the belt layer composite and inflate the forming. The two sets of main machines work independently, greatly improving work efficiency.

[0034] The specific effect analysis is as follows:

[0035] 1. The first feeding rack or the second feeding rack has a clever structural design. The rubber material is guided away by the feeding trolley. The rubber material roll is sleeved on the I-wheel. The trolley driving motor drives the I-wheel to rotate, thereby guiding away the rubber material. The guided rubber material is transported to the conveying rack to continue to move forward. The rubber material is centered by the centering mechanism, and the position of the rubber material is adjusted by the deviation correction mechanism. After adjustment, it is automatically cut by the cutting mechanism. The cut rubber material is transported to the conveying template and then transported to the belt drum through the front template. The present invention has a high degree of automation, reduces manual operations, and improves work efficiency;

[0036] 2. The rubber in the belt feeder is transported to the corresponding conveying mechanism or the lower discharging template, which can meet the feeding requirements of four different rubber materials, and realize the transmission of multiple rubber materials on the same feeder. There is no need to feed multiple rubber materials on multiple feeders, which reduces the space occupied by the equipment, and has a small space occupation and high conveying efficiency. In addition, automatic conveying can be achieved through the conveying mechanism, which reduces material stretching and improves tire quality. Automatic cutting is achieved through the cutting mechanism, which reduces the labor intensity of workers, especially the cutting of thick rubber materials. Automatic cutting not only has a good cutting effect;

[0037] 3. The fixed-edge correction device detects whether the two sidewall rubbers are symmetrically distributed through the correction electric eye mechanisms respectively arranged on the left sidewall correction mechanism and the right sidewall correction mechanism. If not, the motor 14 is controlled to work through the PLC controller, and the motor 14 drives the correction roller 12 to move left and right along the length direction of the first linear guide rail 9, thereby driving the rubber to move and adjust the position of the rubber. Since the correction roller 12 is rotatable, the stretching and wear during material transportation can be reduced. If it is necessary to adjust the position of the rubber significantly, the PLC controller drives the swing cylinder 4 to work, and the swing cylinder 4 drives the inner shaft 17 to swing with the connecting shaft 16 as the axis. The swing roller 18 flips upward and lifts the rubber. After the rubber is lifted, the position of the correction roller 12 is readjusted by the motor 14. After adjustment, the swing roller 18 flips downward, the rubber contacts the correction roller 12, and continues to move forward. Repeating this process many times can achieve a significant adjustment of the position of the rubber. The present invention can achieve better relative center symmetry distribution of two sidewall rubbers on the feeding rack without deviation, so that the materials can be transported from the feeding rack to the forming drum to achieve center symmetry lamination, thereby ensuring the precision and quality of the manufactured tire;

[0038] 4. The tire blank after one stage of the transfer trolley is installed on the columnar forming drum. The tire blank after one stage needs to be removed from the forming drum first. The first horizontal movable frame and the second horizontal movable frame are unfolded in sequence to make the clamping mechanism close to the forming drum, and the tire blank is clamped by the clamping mechanism. Then the first horizontal movable frame and the second horizontal movable frame are retracted to remove the tire blank from the forming drum. The distance between the clamping mechanisms on both sides and the middle clamping mechanism can be adjusted by the screw rod combination, so that tire blanks of different lengths can be clamped. Since the two facing arc-shaped clamping plates can be driven by the cylinder to move closer to each other, tire blanks of different diameters can be clamped. The tire blank is transferred from the first stage to the second stage forming drum. The angle needs to be adjusted before it can be installed on the second stage forming drum. Therefore, the tire blank angle adjustment is achieved by rotating the bracket, so that the tire blank can be smoothly installed on the second stage forming drum. It is easy to use and has high work efficiency. It is suitable for transporting tire blanks of various specifications and has a good transportation effect.

[0039] 5. The rotating mechanism drives the small gear to rotate through the driving motor, and the small gear drives the large gear to rotate. The rotating large gear drives the rotating main machine on the bottom plate of the rotating main machine to rotate together. The four locking mechanisms are distributed in degrees, which can realize the positioning of the rotating main machine in four directions. During operation, the locking cylinder of the locking mechanism retracts the positioning rod. When the rotating main machine moves to the required position, the proximity switch sensing block triggers the proximity switch, and the locking cylinder pushes the positioning rod to move in the direction of the large gear, so that the positioning rod blocks the gap between the two fixed blocks, thereby locking the positioning block of the rotating main machine and realizing accurate and reliable positioning of the rotating main machine. The locking cylinder drives the positioning rod to extend and retract. There are four fixed blocks on the left and right sides of the positioning rod. After positioning, the tangential force transmitted by the main machine is all applied to the rotating main machine positioning block and the positioning rod. The positioning rod finally transmits the force to the fixed blocks on the left and right sides. The locking cylinder does not bear torque, and only the tangential friction force produces a very small force, which prolongs the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The first feeding rack 4 or the second feeding rack 8 includes an upper discharge template 1-1 and a lower discharge template 1-2 located below the upper discharge template 1-1. The upper discharge template 1-1 and the lower discharge template 1-2 can be extended and retracted toward the carcass drum 3. The upper discharge template 1-1 corresponds to three rubber material conveying mechanisms arranged up and down, namely, the first conveying mechanism 1-4, the second conveying mechanism 1-5, and the third conveying mechanism 1-6. The three conveying mechanisms and the lower discharge template 1-2 each correspond to a feeding trolley 1-3. A centering device or an edge correction device is provided between the feeding trolley 1-3 and the conveying mechanism and the lower discharge template 1-2 according to the type of rubber material. A cutting mechanism 1-7 is installed on each conveying mechanism. The first conveying mechanism 1-4 and the second conveying mechanism 1-5 have the same structure and are both trapezoidal. The third conveyor 1-6 is horizontal. Therefore, it can meet the feeding requirements of 4 different rubber materials, and occupies a small space. Moreover, each layer does not interfere with each other and can work independently, effectively utilizing the template and improving efficiency.

[0079] The first conveying mechanism 1-4 and the second conveying mechanism 1-5 both include an inclined first conveyor belt 1-8, a horizontal second conveyor belt 1-9 and a third conveyor belt 1-10, and an inclined fourth conveyor belt 1-27. The third conveying mechanism 1-6 includes a horizontal second conveyor belt 1-9 and a third conveyor belt 1-10. The material is conveyed to the second conveyor belt 1-9 by the first conveyor belt 1-8. A cutter is provided between the second conveyor belt 1-9 and the third conveyor belt 10. When the required length is reached, the cutter cuts the material, and the cut material continues to be conveyed forward to the fourth conveyor belt 1-27 to wait for loading.

[0080] The feeding trolley 1-3 includes a trolley driving motor 1-28 mounted on the trolley body and an I-shaped wheel 1-12 with a rolled rubber material on the outside. The trolley driving motor 1-28 drives the I-shaped wheel 1-12 to rotate, thereby guiding the rubber material;

[0081] The cutting mechanism 1-7 is arranged between the second conveyor belt 1-9 and the third conveyor belt 1-10. The cutting mechanism 1-7 includes a cutting device and a pressure plate device. The cutting device includes a cutting linear guide rail 1-13 across the conveyor belt. A cutting seat 1-14 capable of sliding left and right along the length direction of the cutting linear guide rail 13 is installed on the cutting linear guide rail 1-13. A cutting knife 1-30 is installed below the knife seat 1-14. A cutting synchronous belt 1-15 linked to the knife seat 14 is arranged along the length direction of the cutting linear guide rail 1-13. The synchronous belt 1-15 is driven by a cutting motor 1-16; through the cutting motor 1 -16 drives the synchronous belt 1-15, and the synchronous belt 1-15 drives the cutter 1-30 to move, thereby cutting the rubber material; the pressure plate device includes two cylinders 1-17 and a swing rod 1-18 driven by the two cylinders 1-17, the swing rod 1-18 is connected to a long axis 1-19 across the conveyor belt, and a pressure plate 1-20 for pressing the rubber material to facilitate cutting is also installed along the length direction of the long axis 1-19; the cylinder 17 drives the swing rod 1-18 to rotate, the swing rod 1-18 drives the long axis 1-19 to rotate, and the long axis 1-19 drives the pressure plate 1-20 to flip, thereby pressing the rubber material to facilitate cutting;

[0082] The upper discharging template 1-1 and the lower discharging template 1-2 have the same structure, both of which include a mobile frame 1-21 and a discharging conveyor belt 1-22 installed on the mobile frame 1-21, the discharging conveyor belt 1-22 is driven by a discharging motor 1-23, a discharging linear guide 1-26 is installed at the bottom of the mobile frame 1-21, a slider 1-24 is installed on the discharging linear guide 1-26, the bottom of the slider 1-24 is fixed on the fixed frame 1-25, a discharging driving cylinder 1-29 is installed on the side of the fixed frame 1-25, and the output end of the discharging driving cylinder 1-29 is connected to the mobile frame 1-21.

[0083] When in use, the cut 1# rubber material continues to be transferred forward to the upper discharge template 1-1 to wait, and the rubber material behind continues to be transmitted and cut. After cutting, it waits for the template signal on the conveyor belt. The same working process is carried out on the other layers of conveyor belts, and the rubber materials are cut and wait for the template signal. The upper discharge template 1-1 or the lower discharge template 1-2 is divided into a retractable type. After the mobile frame 1-21 extends to transfer the 1# rubber material to the forming drum 1-11, the template does not need to be returned, and the 3# material will continue to be transferred to the upper discharge template 1-1, and the 4# rubber material will continue to be loaded. After the 4# rubber material is loaded, the mobile frame 1-21 retracts and transfers the waiting 2# rubber material to the upper discharge template 1-1 to wait. At the same time, the lower discharge template 1-2 extends to load the 4# rubber material. When the lower discharge template 1-2 transfers the material to the drum, the 2# material of the upper discharge template 1-1 has been loaded and is in a waiting state, and the 2# material continues to be conveyed. Each layer does not interfere with each other and can work independently, effectively utilizing the template and improving efficiency.

[0084] The centering device is similar in structure to the edge correction device. The edge correction device includes two symmetrical left and right tire side correction mechanisms. The left tire correction mechanism or the right tire side correction mechanism includes a swinging roller mechanism for lifting the rubber material, a correction roller mechanism for driving the rubber material to move left and right, and a correction electric eye mechanism for detecting the edge position of the rubber material. The swinging roller mechanism, the correction roller mechanism, and the correction electric eye mechanism are installed in sequence from the feeding trolley 1-3 to the first feeding rack 4 or the second feeding rack 8. The swinging roller mechanism, the correction roller mechanism, and the correction electric eye mechanism are all controlled by the PLC controller and are all installed at the feeding port of the first feeding rack 4 or the second feeding rack 8.

[0085] The centering device includes a swinging roller mechanism, a correcting roller mechanism, and a correcting electric eye mechanism. The correcting electric eye mechanism includes left and right lead screws. A handwheel is installed at one end of the left and right lead screws. Two nuts and a fixed seat are installed on the left and right lead screws. Two sliders are installed on the linear guide rail. The fixed seat is installed on the slider. CCD infrared electric eyes are installed on both fixed seats. The deflection correction electric eye mechanism detects whether the rubber material is transmitted along the center of the conveyor belt. If it is not transmitted along the center of the conveyor belt, the PLC controller controls the deflection correction motor to work, and the deflection correction motor controls the deflection correction roller to move along the linear axis, thereby driving the rubber material to move and adjust the position of the rubber material. Since the deflection correction roller is rotatable, the stretching and wear during material transportation can be reduced. If the position of the rubber material needs to be greatly adjusted, the PLC controller drives the swing cylinder to work, and the swing cylinder drives the connecting shaft to swing with the inner shaft as the axis. The connecting shaft flips upward and lifts the rubber material. After the rubber material is lifted, the deflection correction roller position is readjusted by the deflection correction motor. After adjustment, the connecting shaft flips downward, and the rubber material contacts the deflection correction roller and continues to move forward. Repeating multiple times can achieve a large adjustment of the position of the rubber material. The present invention can make the material always be transmitted in the center of the conveyor belt without deviation, so as to achieve the purpose of centering.

[0086] The deflection-correcting roller mechanism includes two connecting plates 2-3 installed on the first feeding rack 4 or the second feeding rack 8, a crossbeam 2-7 is installed between the two connecting plates 2-3, a first linear guide 2-9 is installed on the crossbeam 2-7, two sliders 8 are installed on the first linear guide 2-9, L-shaped fixed seats 2-10 are installed on the two sliders 2-8, a plurality of shafts 2-11 are installed between the two L-shaped fixed seats 2-10, a deflection-correcting roller 2-12 that can rotate around the shaft 11 is installed on each shaft 2-11, a connecting rod 2-13 is installed on the L-shaped fixed seat 2-10, and the connecting rod 2-13 is also connected to the output end of the motor 2-14; the deflection-correcting roller 2-12 is made of aluminum alloy to reduce weight. When materials are transported, the materials drive the deflection-correcting roller 2-12 to rotate, and a slider 2-8 is arranged under the L-shaped fixed seat 2-10, so that the deflection-correcting roller 2-12 can not only rotate but also move left and right as a whole;

[0087] The top of the L-shaped fixing seat 2-10 is arc-shaped, and there are three correcting rollers 2-12, which are arranged in an arc shape from front to back; the arc-shaped design can make the correcting roller 2-12 and the sidewall rubber contact surface larger, and the correcting effect is good;

[0088] The swing roller mechanism includes a swing cylinder 2-4 installed on one of the connecting plates 2-3 and a driving sprocket 2-5 driven by the swing cylinder 2-4, the driving sprocket 5 is connected to the driven sprocket 2-6, supports 2-15 are installed on both sides of the first linear guide 2-9, a connecting shaft 2-16 is installed between the two supports 2-15, swing arms 2-28 are installed at both ends of the connecting shaft, an inner shaft 2-17 is installed between the two swing arms 2-28, and a swing roller 2-18 that can rotate with the inner shaft 2-17 as the axis is installed on the outside of the inner shaft 17 through a rolling bearing;

[0089] The deflection correction electric eye mechanism includes a second linear guide rail 2-19 spanning two connecting plates 2-3 and a screw rod 2-23 arranged above the second linear guide rail 2-19, a hand wheel 2-26 is installed at one end of the screw rod 2-23, a nut 2-24 and a fixed seat 22 are installed on the screw rod 2-23, a slider 2-21 is installed on the second linear guide rail 2-19, the fixed seat 22 is installed on the slider 2-21, a CCD infrared electric eye 2-25 is installed on the fixed seat 2-22, the second linear guide rail 2-19 is installed on the fixed beam 2-20, and both ends of the fixed beam 2-20 are installed on the connecting plate 2-3. The second linear guide rail 2-19 is installed on the fixed beam 2-20, and both ends of the fixed beam 2-20 are installed on the connecting plate 2-3. By shaking the hand wheel 2-26, the position of the CCD sensor 2-25 can be adjusted.

[0090] Working principle: The electric eye mechanisms respectively arranged on the left side tire correction mechanism and the right side tire correction mechanism detect whether the two side tire rubbers are deviated. If they are deviated, the motor 2-14 is controlled by the PLC controller to work, and the motor 2-14 drives the correction roller 2-12 to move left and right along the length direction of the first linear guide rail 2-9, thereby driving the rubber to move and adjust the position of the rubber. Since the correction roller 2-12 is rotatable, the stretching and wear during material transportation can be reduced. If the position of the rubber needs to be adjusted significantly, the PLC controller drives the swing cylinder 2-4 to work, and the swing cylinder 2-4 drives the inner shaft 2-17 to swing around the connecting shaft 2-16. The swing roller 2-18 flips upward and lifts the rubber. After the rubber is lifted, the motor 2-14 readjusts the position of the correction roller 2-12. After adjustment, the swing roller 2-18 flips downward, and the rubber contacts the correction roller 2-12 and continues to move forward. Repeating multiple times can achieve a significant adjustment of the position of the rubber.

A third driving mechanism for driving the rotating frame 3-4 to rotate is installed between the moving frame 3-3 and the rotating frame 3-4; since the tire blank after one stage is installed on the cylindrical molding drum, the tire blank after one stage needs to be removed from the molding drum first, and the first transverse movable frame 3-2 and the second transverse movable frame 3-3 are unfolded in sequence, so that the clamping mechanism 3-5 is close to the molding drum, and the tire blank is clamped by the clamping mechanism 3-5, and then the first transverse movable frame 3-2 and the second transverse movable frame 3-3 are contracted to remove the tire blank from the molding drum. The tire blank is transferred from the first stage to the second stage molding drum, and the angle needs to be adjusted before it can be installed on the second stage molding drum.

[0096] The rotating mechanism 10 includes a cylindrical support seat 4-2 installed in the center of the base 4-1, and four equally spaced mounting seats 4-3 are arranged along the outer wall of the support seat 4-2. The base 4-1, the support seat 4-2, and the mounting seat 4-3 are an integrated structure, and each mounting seat 4-3 is provided with a locking mechanism for locking the rotating host positioning block 4-4. A driving motor 4-5 is installed on the base 4-1, and a small gear 4-6 is installed at the output end of the driving motor 4-5. A large gear 4-7 meshing with the small gear 4-6 is installed on the support column 4-2, and a rotating host bottom plate 4-8 is installed on the upper surface of the large gear 4-7, and a proximity switch sensing block 9 is installed on the lower surface.

[0097] Specific structure of the locking mechanism: The locking mechanism includes a locking cylinder 4-11 and a U-shaped positioning rod 4-12 driven by the locking cylinder 4-11. The positioning rod 4-12 moves toward the large gear 4-7 under the drive of the locking cylinder 4-11. Two fixed blocks 4-14 are provided on the left and right sides of the positioning rod 4-12. The fixed blocks 4-14 are installed on the mounting seat 4-3. The rotating mainframe positioning block 4-4 can pass through the two fixed blocks 4-14. When working, the locking cylinder 4-11 of the locking mechanism retracts the positioning rod 4-12. When the rotating mainframe moves to the required position, the proximity switch sensing block 4-9 triggers the proximity switch 4-10, and the locking cylinder 4-11 pushes the positioning rod 4-12 to move toward the large gear 4-7, so that the positioning rod 4-12 blocks the gap between the two fixed blocks 4-14, thereby locking the rotating mainframe positioning block 4-4 and realizing accurate and reliable positioning of the rotating mainframe.

The positioning rod 4-12 finally transmits the force to the fixed blocks 4-14 on the left and right sides. The locking cylinder 4-11 does not bear torque, and only the tangential friction force produces a very small force, which prolongs the service life.
