Description

Technical Field

[0001] The present invention relates to the technical field of tire manufacturing, and particularly relates to a rubber strip smoothing, feeding and conveying device based on bead composite processing. Background Art

[0002] The heel of the tire refers to the part where the outer side of the bead is in contact with the rounded corner of the rim bead seat. Its center is the bead. The bead is the part of the tire installed on the rim and is mainly composed of a bead wire and a triangular rubber strip. It is an important component of the tire. Its main functions include fixing the tire, transmitting power and steering, supporting the tire wall, enhancing direction stability, providing steering accuracy, rigid transition, extending the service life of the tire, and improving riding comfort.

[0003] The bead wire is used for the bead part of the tire and is one of the main skeleton materials of the tire. The function of the tire bead is to firmly fix the tire on the rim and bear various interaction forces between the tire and the rim. In short, the bead of the semi-steel radial tire plays an important role in improving the structural stability of the tire, protecting the tire side, enhancing the strength of the tire body, balancing stress distribution, reducing temperature, reducing noise, enhancing wet grip, and adapting to different climate conditions;

[0004] In the production process of semi-steel radial tires, the bead rubber compounding is an important link. The original bead compound production line consists of four production equipment units: rubber strip extrusion, cooling, storage, and compounding. And due to the limitations of the height of the rubber strip, the inner diameter of the bead wire, and the storage length, it can only complete the production of beads with a small range of specifications. During the feeding process of the triangular rubber strip, skew or even "derailment" feeding may occur due to different specification factors, directly affecting the smooth compound processing of the bead. Therefore, this application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide a rubber strip smoothing, feeding and conveying device based on bead composite processing, which is used to solve the problem that the bead composite processing fails due to skew caused by different specification factors during the feeding of the triangular rubber strip.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A rubber strip smoothing, feeding and conveying device based on bead composite processing includes a continuously arranged base and a chassis. A picking component and a buffer component for receiving the feeding of the triangular rubber strip are installed on the base, and a contraction component for correcting the feeding of the triangular rubber strip is installed on the chassis;

[0007] The contraction assembly includes a bracket installed on the chassis. In the middle of the lower end of the bracket, a floating roller is rotatably installed through a floating rod. On one side of the upper end of the bracket, a conveying fixed roller is installed. A conveying contraction roller is connected through a rotation fulcrum in the feeding direction of the conveying fixed roller. At one end of the base close to the feeding side, a buffer assembly is installed. The buffer assembly includes symmetrically arranged bottom support seats and upper moving seats, and cross - arranged lower storage wheels and upper storage wheels are respectively installed on the bottom support seats and the upper moving seats.

[0008] It is further set that: a cooling assembly is arranged between the base and the chassis. The cooling assembly includes a platform frame and a cooling roller disc. Diagonal bead wheels are installed at the upper end of the platform frame corresponding to the cooling roller disc.

[0009] It is further set that: a motor is installed on one side of one of the platform frames. The output end of the motor is horizontally connected through a speed reducer to a rotating shaft connected to the cooling roller disc. Rotating rods connected to the diagonal bead wheels are jointly installed at the upper end of the platform frame.

[0010] It is further set that: the floating rod is rotatably arranged in the middle of the bracket. A floating arm is sleeved outside the floating rod. The floating roller is rotatably installed at the bottom of the floating arm. The floating roller is of a symmetric cone structure. A conveying rubber groove is opened in the middle of the floating roller, and a counterweight rod is installed at the upper end of the floating arm.

[0011] It is further set that: a second cylinder is rotatably installed in the middle of the bracket. The output end of the second cylinder is rotatably connected to the lower end of the conveying contraction roller. The rotation fulcrum includes a bearing seat arranged at the upper end of the bracket. The conveying contraction roller deflects through the bearing seat.

[0012] It is further set that: the picking - up assembly includes a sliding rod seat arranged on the base near the extruder side. A slider is installed on the sliding rod seat. Symmetrically arranged picking - up wheels are installed on the slider. A buffer driving wheel is installed at the upper end and far side of the sliding rod seat.

[0013] It is further set that: the buffer assembly further includes a guiding wheel rotatably arranged on the far side of the bottom support seat. A first cylinder facing downward and connected to the bottom support seat is installed on the upper moving seat.

[0014] It is further set that: a vertical linear rail slidingly connected to the upper moving seat is installed on one side of the bottom support seat, and a support rod connected to the sliding rod seat is installed in the middle on the outside of the vertical linear rail.

[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention aims at the technical problem that during the feeding process of the apex strip in bead composite processing, skew or even "derailment" feeding occurs due to the influence of different specification factors. It is applied to the feeding process of the apex strip in bead composite processing, which is basically similar to the feeding principle of the apex strip in the prior art. The main difference lies in the improvement of the tension control structure and the picking-up and feeding structure during the feeding of the apex strip, specifically reflected in:

[0017] Through the folding guidance of the conveying and shrinking rollers and the automatic eccentric adjustment of the cooling roller disc for the apex strip, the apex strip can be fed at a stable speed and adapted to its specifications. On this basis, through the setting of the floating picking-up wheel and the upper storage wheel cooperating with the lower storage wheel, the apex strip can be fed at a constant speed in a dynamic floating winding manner during the picking-up and buffering stages, that is, based on the folding guidance and automatic eccentric adjustment for feeding, supplemented by the constant-speed feeding process of dynamic floating winding, which can effectively realize the stable feeding of the apex strip during the bead composite processing.

[0018] 2. During the tension control process of the apex strip, three combined tension control methods are jointly formed by the moving and fixed pulley structure composed of the lower storage wheel and the upper storage wheel and the telescopic structure of cylinder 1 during the picking-up stage and the buffering stage, so as to be able to adapt to the feeding precision control of different sizes of apex strips.

[0019] Specifically: The tension control methods include three combined methods. One is that the picking-up wheel cooperates with the slider to change the vertical position independently. The second is that cylinder 1 drives the upper moving seat to change the vertical position, thereby changing the distance between the lower storage wheel and the upper storage wheel. The third is the combination of the first and the second above, which can not only change the vertical position of the picking-up wheel but also change the distance between the lower storage wheel and the upper storage wheel. The combination of the two constitutes three combined tension controls to ensure the stability of the buffer during the feeding process of the apex strip and make adaptive settings according to the progress of bead composite processing.

Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Aiming at the technical problem of skewed or even "derailed" feeding during the feeding process of the triangular rubber strip during bead composite processing due to different specification factors, the following technical solutions are proposed:

[0032] Refer to Figures 1-8 As shown, in this embodiment, the rubber strip straightening and feeding conveying device based on bead composite processing includes a continuously arranged base 5 and a chassis 6. A pick-up component 4 and a buffer component 1 for receiving the feeding of the triangular rubber strip are installed on the base 5, and a shrinkage component 3 for correcting the feeding of the triangular rubber strip is installed on the chassis 6;

[0033] The contraction assembly 3 includes a bracket 301 installed on the chassis 6. In the middle of the lower end of the bracket 301, a floating roller 303 is rotatably installed through a floating rod 302. On one side of the upper end of the bracket 301, a conveying fixed roller 305 is installed. In the feeding direction of the conveying fixed roller 305, a conveying contraction roller 306 is connected through a rotation fulcrum. In the middle of the bracket 301, a second cylinder 304 is rotatably installed. The output end of the second cylinder 304 is rotatably connected to the lower end of the conveying contraction roller 306. The rotation fulcrum includes a bearing seat 307 arranged at the upper end of the bracket 301, and the conveying contraction roller 306 deflects through the bearing seat 307;

[0034] For the active control process of the conveying contraction roller 306, it is mainly carried out through the inclination angle of the conveying contraction roller 306 relative to the conveying fixed roller 305. The second cylinder 304 drives the conveying contraction roller 306 to deflect, so that the transmission direction and the control of the end tension of the triangular rubber strip on the conveying fixed roller 305 and the conveying contraction roller 306 are changed, and the transmission accuracy control is carried out in line with the specifications of the triangular rubber strip;

[0035] Refer to Figure 2 As shown, at one end of the base 5 close to the feeding side, a buffer assembly 1 is installed. The buffer assembly 1 includes symmetrically arranged bottom support seats 101 and upper moving seats 102, and cross - arranged lower storage wheels 103 and upper storage wheels 104 are installed on the bottom support seats 101 and the upper moving seats 102 respectively;

[0036] Among them, the lower storage wheels 103 and the upper storage wheels 104 are distributed in a staggered up - and - down manner, and the spacing can be adjusted according to the parameter specifications of the triangular rubber strip. After the spacing is adjusted, the length and height of the cached triangular rubber strip are actively controlled, so as to match the subsequent bead composite processing rate, and the forming efficiency of the integrated bead composite processing equipment is improved;

[0037] Refer to Figure 2 and Figure 3 As shown, the picking - up assembly 4 includes a sliding rod seat 401 arranged on the base 5 near the extruder side. A slider 402 is installed on the sliding rod seat 401, and symmetrically arranged picking - up wheels 403 are installed on the slider 402. The picking - up wheels 403 are of a vertically slidable structure, which can adjust the initial picking - up position according to the triangular rubber strip led out by the extruder, and can cooperate with the buffer driving wheel 404 to adjust the subsequent buffer passing - out position. The picking - up and passing - out steps can be effectively adjusted adaptively according to the parameter specifications of the triangular rubber strip, and the buffer rate can be adjusted according to the bead composite processing progress;

[0038] Refer to Figure 4 and Figure 5As shown, a cooling assembly 2 is arranged between the base 5 and the bottom frame 6, and the cooling assembly 2 includes a stand 201 and a cooling roller disc 203, and an inclined bead wheel 202 is installed at the upper end of the stand 201 corresponding to the cooling roller disc 203, and a motor 204 is installed on one side of one of the stands 201, and the output end of the motor 204 is transversely connected to a rotating shaft 205 connected to the cooling roller disc 203 through a reduction box, and a rotating rod 206 connected to the inclined bead wheel 202 is installed on the upper end of the stand 201;

[0039] Reference Figure 6 As shown, the floating rod 302 is rotatably arranged in the middle of the bracket 301, the floating arm 308 is sleeved on the outside of the floating rod 302, the floating roller 303 is rotatably installed at the bottom of the floating arm 308, the floating roller 303 is a symmetrical cone structure, a conveying glue groove is opened in the middle of the floating roller 303, and a counterweight rod 309 is installed on the upper end of the floating arm 308.

[0040] Basic principle: The feeding process of the apex rubber strip used in the tire bead composite processing of the present invention is basically similar to the feeding principle of the apex rubber strip in the prior art. The difference is mainly the improvement of the tension control structure and the receiving and feeding structure during the feeding of the apex rubber strip, which is specifically reflected in:

[0041] The folding guide of the conveying and shrinking roller 306 and the automatic eccentric adjustment of the cooling roller disc 203 enable the apex rubber strip to be fed at a steady speed and adapted to its specifications. On this basis, the floating receiving wheel 403 and the upper storage wheel 104 cooperate with the lower storage wheel 103 to realize the speed-based feeding of the apex rubber strip in the receiving and caching stage in a dynamic floating winding manner, that is, the feeding based on the folding guide and the automatic eccentric adjustment, supplemented by the speed-based feeding process of the dynamic floating winding, can effectively realize the stable feeding of the apex rubber strip in the tire bead composite processing process;

[0042] The feeding process of the triangular rubber strip in the present invention is briefly described as follows: feeding the extruder, extruding the triangular rubber strip through the extruder, introducing the triangular rubber strip into the receiving component 4, the triangular rubber strip passing through the cooling component 2 to complete cooling, introducing the triangular rubber strip into the buffer component 1 for temporary storage, passing the triangular rubber strip into the shrinking component 3 for feeding guide feeding, and entering the horizontal rotating bonding disk to complete bonding with the wire ring and ejecting the tire ring.

[0043] Embodiment 2: This embodiment further optimizes the structure of Embodiment 1:

[0044] Reference Figures 1-8 As shown, a cache driving wheel 404 is installed at the far side of the upper end of the sliding rod seat 401, and the cache assembly 1 also includes a guide wheel 107 rotatably arranged at the far side of the bottom bracket seat 101, and a cylinder 106 facing downward and connected to the bottom bracket seat 101 is installed on the upper moving seat 102;

[0045] On one side of the bottom support base 101, a vertical linear guide 105 slidably connected to the upper moving base 102 is installed, and a support rod 7 connected to the sliding rod base 401 is installed in the middle of the outer side of the vertical linear guide 105.

[0046] Structural advantages: Combining the above-mentioned Embodiment 1 and the attached Figure 2 As shown, it should be noted that: in the picking-up stage and the buffering stage, three combined tension control methods are jointly composed of the movable and fixed pulley structures formed by the lower storage wheel 103 and the upper storage wheel 104 and the telescopic structure of the first cylinder 106, so as to be able to adapt to the feeding precision control of different sizes of triangular rubber strips;

[0047] It should be noted again that: the tension control method includes three combined methods. One is that the picking-up wheel 403 cooperates with the slider 402 to change the vertical position independently; the second is that the first cylinder 106 drives the upper moving base 102 to change the vertical position, and then changes the distance between the lower storage wheel 103 and the upper storage wheel 104; the third is the combination of the above-mentioned one and two, which can not only change the vertical position of the picking-up wheel 403, but also change the distance between the lower storage wheel 103 and the upper storage wheel 104. The combination of the two constitutes three combined tension controls, ensuring the buffering stability during the feeding process of the triangular rubber strip and making adaptive settings according to the progress of the bead composite processing.

[0048] Embodiment 3: Refer to Figures 1-8 As shown, this embodiment combines the technical contents of Embodiment 1 and Embodiment 2 to form a method for straightening and feeding the rubber strip based on the bead composite processing, including the following steps:

[0049] S1: Feeding of the extruder: Manually feed the rubber strip into the feeding port, straighten the rubber strip to prevent the rubber strip from curling and knotting, and ensure that the rubber strip can be normally and smoothly introduced into the feeding port; Prepare for starting the extruder, check whether the temperatures of all sections of the extruder are normal, and start the extruder after confirmation; On the operation panel at the head position of the extruder, there is an extruder speed adjustment switch. First, slow down the speed of the extruder, and then gradually increase the speed after it is normal;

[0050] S2: Extruding the triangular rubber strip by the extruder: The picking-up conveyor belt is in a vertical position, and check whether the shape of the extruded triangular rubber meets the requirements, and measure whether the dimensions of each part of the triangular rubber are within the process requirements. If the shape of the triangular rubber does not meet the requirements, the triangular rubber die plate needs to be trimmed, and then try to extrude until the shape of the extruded triangular rubber meets the requirements; If the buffer assembly 1 is in the "full material" state, the extrusion of the extruder is paused;

[0051] S3: Introducing the triangular rubber strip into the picking-up assembly 4: The rubber strip is wound and introduced through the picking-up wheel 403;

[0052] S4: The triangular rubber strip is inserted into the cooling assembly 2 for cooling. During cooling, the eccentricity of the cooling roller disc 203 is adjusted according to the specifications of the triangular rubber strip, so as to adapt different specifications of triangular rubber strips to pass through between the cooling roller disc 203 and the inclined bead wheel 202;

[0053] S5: The triangular rubber strip is introduced into the buffer assembly 1 for temporary storage. It is wound around the lower storage wheel 103 in the buffer assembly 1 through the buffer drive wheel 404, and alternately passes through the lower storage wheel 103 and the upper storage wheel 104 in sequence and finally passes out through the guide wheel 107;

[0054] S6: The triangular rubber strip is inserted into the shrinkage assembly 3 for feeding and guiding. The inclination angle of the conveying shrinkage roller 306 relative to the conveying fixed roller 305 is adjusted, and the conveying shrinkage roller 306 is driven by the cylinder two 304 to deflect, so that the transmission direction and the end tension control of the triangular rubber strip on the conveying fixed roller 305 and the conveying shrinkage roller 306 are changed, meeting the transmission accuracy control according to the specifications of the triangular rubber strip;

[0055] S7: Enter the horizontal rotary fitting disc to complete the fitting with the bead wire and eject the bead. The bead wire is manually placed on the fitting disc. The fitting disc expands and positions the bead wire under the action of the pneumatic gripper. The triangular rubber is sent to the bead wire pressing position. The clamping device on the horizontal rotary fitting disc presses the triangular rubber and fits it on the bead wire. The horizontal rotary fitting disc drives the bead wire and the triangular rubber to rotate simultaneously. At the same time, the main and auxiliary sets of pressing wheel devices press the triangular rubber on the bead wire. The servo motor drives the fitting disc to rotate. After the fixed length is completed, the front end cutter of the triangular rubber cuts. The clamping ring on the horizontal rotary disc resets under the action of the cylinder; the servo motor continues to rotate a small step at a fixed length for bonding, and the two extrusion wheels roll to press the joint well; the fitting disc is positioned and released, and the ejecting device ejects the bead.

[0056] In summary: On the one hand, it is mainly the improvement of the tension control structure and the picking-up and feeding structure during the feeding of the triangular rubber strip; specifically reflected in: through the folding guidance of the conveying shrinkage roller 306 and the automatic eccentricity adjustment of the cooling roller disc 203, the triangular rubber strip can be fed at a stable speed and adapted to its specifications; on this basis, through the setting of the floating picking-up wheel 403 and the upper storage wheel 104 cooperating with the lower storage wheel 103, the triangular rubber strip can be fed at a constant speed in a dynamic floating winding manner during the picking-up and buffering stages; that is, based on the feeding with folding guidance and automatic eccentricity adjustment, supplemented by the constant-speed feeding process with dynamic floating winding, the stable feeding of the triangular rubber strip during the bead composite processing process can be effectively realized;

[0057] On the other hand, through the picking-up stage and the buffering stage, three combined tension control methods are jointly formed by the moving and fixed pulley structure composed of the lower storage wheel 103 and the upper storage wheel 104 and the telescopic structure of the cylinder one 106, so as to be able to adapt to the feeding precision control of different sizes of triangular rubber strips.

[0058] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of the present technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they shall fall within the protection scope of the present invention.
