Description

Technical Field

[0001] This invention relates to the field of tire cord fabric production technology, and more particularly to a continuous impregnation equipment for tire cord fabric production. Background Technology

[0002] Tire cord fabric is a type of skeleton fabric used in tires, woven with high-strength ply yarns as warp and medium- or fine single yarns as weft. Because of its tightly arranged warp and sparsely arranged weft, it resembles a curtain, hence the name tire cord fabric. During production, to enhance the adhesion between the tire cord fabric and rubber, and to improve the strength and stability of the cord fabric, a continuous impregnation device is used to impregnate it with adhesive. Currently, in the continuous impregnation process, the cord fabric is guided by rollers through a bath containing adhesive solution, allowing the solution to contact the sides of the fabric and gradually penetrate into the interior, completely saturating and coating the warp and weft. However, due to the small gaps between the warp and weft of the cord fabric and the poor fluidity of the adhesive solution, the impregnation time per unit area is long, resulting in a slow impregnation speed and low efficiency. Summary of the Invention

[0003] This invention provides a continuous impregnation equipment for tire cord fabric production, which overcomes the shortcomings of existing tire cord fabric impregnation processes, such as low impregnation efficiency due to the small gap between the warp and weft yarns and poor flowability of the adhesive.

[0004] The technical solution of this invention is: a continuous impregnation equipment for producing tire cord fabric, comprising:

[0005] A housing, wherein a circulation pump is installed in the housing, and the inlet and outlet of the circulation pump are both connected to the interior of the housing;

[0006] Two extrusion strips are fixedly connected inside the housing. Two inner support rollers are rotatably connected inside the housing. The inner support rollers are in contact with the adjacent extrusion strips. The inlet and outlet of the circulating pump are located on the upper and lower sides of the extrusion strips, respectively.

[0007] The mounting component is slidably and sealed to the housing. The mounting component is rotatably and sealed to a mounting plate. The mounting component is equipped with a motor. The output shaft of the motor is fixedly connected to the mounting plate. An annularly distributed support strips are fixedly connected to the side of the mounting plate away from the motor. A sealing ring is fixedly connected to the side of all the support strips away from the mounting plate. The sealing ring is in contact with the housing.

[0008] Furthermore, it also includes:

[0009] Two outer support rollers are rotatably connected to the upper side of the housing. Two mounting blocks are slidably connected to the upper side of the housing. A spring is fixed between the mounting blocks and the housing. The two mounting blocks are rotatably connected to a squeezing roller, which contacts one of the outer support rollers.

[0010] Furthermore, the mounting plate and all the support bars are completely located within the housing.

[0011] Furthermore, the support bar is provided with a plurality of first limiting grooves and a plurality of second limiting grooves on the side away from the central axis of the mounting plate.

[0012] Furthermore, the minimum distance between the first limiting groove and the central axis of the mounting plate is greater than the minimum distance between the second limiting groove and the central axis of the mounting plate, and all the first limiting grooves and all the second limiting grooves on the same support bar are staggered, with the first limiting grooves and the second limiting grooves being staggered in the circumferential direction.

[0013] Furthermore, it also includes:

[0014] The number of support ribs equal to that of the support strips are all fixed between the mounting plate and the sealing ring. The maximum distance between the support ribs and the central axis of the mounting plate is less than the minimum distance between the second limiting groove and the central axis of the mounting plate.

[0015] Furthermore, it also includes:

[0016] The first electric push rod is installed on the side of the housing near the mounting component. The telescopic end of the first electric push rod is fixedly connected to the mounting component. The height of the central axis of the mounting plate is greater than the height of the central axis of the inner support roller, and the central axes of the two inner support rollers are located in the same horizontal plane.

[0017] Furthermore, it also includes:

[0018] Two mounting bases are fixedly connected to the housing, and the two mounting bases are rotatably connected to two rotating rollers, and the two rotating rollers are wound with a belt.

[0019] Multiple misaligned strips are fixed to the outside of the belt.

[0020] Furthermore, both the first limiting groove and the second limiting groove have an arc-shaped surface on the side closest to the central axis of the mounting plate.

[0021] Furthermore, it also includes:

[0022] The second electric actuator is installed on the side of the housing away from the mounting component;

[0023] A sealing element is rotatably connected to the sealing ring. The support strip and the mounting plate are both in contact with the sealing element. A rectangular through hole is provided on the sealing element.

[0024] Compared with the prior art, the present invention has the following advantages: The present invention utilizes a circulating pump to drive the adhesive liquid in the housing to flow and actively pass through the gap between the warp and weft yarns in the cord fabric, so that the adhesive liquid can quickly coat the surface of the warp and weft yarns of the cord fabric, shortening the time required for the adhesive liquid to coat the warp and weft yarns and improving the impregnation efficiency of the cord fabric.

[0025] Support strips are used to support the fabric, and the first and second limiting grooves are used to support the warp threads individually to separate adjacent warp threads. At the same time, the first and second limiting grooves are used to apply a constraint force to the warp threads, reducing the degree of bending caused by the impact of the adhesive, thereby maintaining the stability of the gaps between the warp threads and improving the uniformity of the adhesive coating on the warp threads.

[0026] Support ribs are used to provide support for the warp threads, preventing them from bending excessively during the impact of the adhesive.

[0027] By inserting a staggered strip into the gap between two adjacent support strips, the curtain fabric is squeezed and deformed, thereby changing the contact position between the curtain fabric and the support strip, so that all parts of the curtain fabric can fully contact the adhesive.

[0028] By using seals to suppress the flow of adhesive, the pressure of the adhesive is increased. This promotes the adhesive to penetrate into the warp and weft yarns of the cord fabric, and also helps to expel air bubbles from the gaps between the warp and weft yarns, thus increasing the contact area between the cord fabric and the adhesive.

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0039] A continuous impregnation equipment for producing tire cord fabric; please refer to [reference needed]. Figures 1-4 The system includes: a housing 1, on which a circulating pump 2 is installed, with both its inlet and outlet connected to the interior of the housing 1; two extrusion strips 3, both fixedly connected to the housing 1, with two inner support rollers 4 rotatably connected inside the housing 1, the inner support rollers 4 contacting adjacent extrusion strips 3, the inlet and outlet of the circulating pump 2 located on the upper and lower sides of the extrusion strips 3 respectively; a mounting component 8, slidably and sealingly connected to the housing 1, with a mounting plate 9 rotatably connected to the mounting component 8, and a motor 10 mounted on the mounting component 8, the output shaft of the motor 10 being fixedly connected to the mounting plate 9; and the mounting plate... A ring of equally spaced support bars 11 is fixedly connected to the side of the mounting plate 9 away from the motor 10. A sealing ring 12 is fixedly connected to the side of all support bars 11 away from the mounting plate 9. The sealing ring 12 is in contact with the housing 1. The mounting plate 9 and all support bars 11 are completely located inside the housing 1.

[0040] The above solution aims to solve the problem of low impregnation efficiency of existing tire cord fabrics due to the small pores of the fabric and the poor flowability of the adhesive. This solution utilizes a circulating pump 2 to drive the adhesive in the housing 1 to flow and pass through the gaps between the warp and weft yarns of the tire cord fabric, so that the adhesive can quickly coat the warp and weft yarn surfaces of the fabric, thereby improving the impregnation efficiency. All support bars 11 form a cylinder, and the outer diameter of the cylinder is equal to the outer diameter of the mounting plate 9 and the sealing ring 12. The housing 1, the two extrusion bars 3, the two inner support rollers 4, and the lower part of the cylinder formed by all support bars 11 together constitute a pressure chamber. The inner support rollers 4 are used to guide the tire cord fabric to adhere to the cylindrical surface formed by all support bars 11. The part of the tire cord fabric entering the pressure chamber is supported by the adjacent support bars 11.

[0041] The housing 1 is connected to an external adhesive storage device. During the impregnation of the cord fabric, the adhesive storage device continuously injects adhesive into the housing 1 to maintain a stable amount of adhesive within the housing 1. The inner support roller 4 can be made of elastic rubber. The mounting plate 9 and the sealing ring 12 are in contact with the inner support roller 4. During the impregnation process, the cord fabric is squeezed between the inner support roller 4 and the adjacent support strip 11. The inner support roller 4 and the adjacent support strip 11 squeeze the cord fabric, causing air bubbles adhering to the warp and weft yarns of the cord fabric to detach from the cord fabric, reducing the air bubble content in the adhesive in the pressurized chamber, thereby improving the impregnation effect of the cord fabric. The inlet of the circulating pump 2 can be installed at an angle. The filter cloth reduces the amount of air bubbles in the adhesive entering the circulating pump 2, thereby reducing the volume of air bubbles in the pressurizing chamber; the squeeze roller 7 and the outer support roller 5 on the left are used to clamp the curtain cloth to squeeze out excess adhesive from the surface of the curtain cloth; the sealing ring 12 is used to provide support for the rear end of the support strip 11, improving the strength of the support strip 11; the mounting plate 9 and all the support strips 11 are located inside the housing 1, so that the adhesive in the housing 1 can completely submerge the mounting plate 9 and all the support strips 11, preventing the mounting plate 9 and all the support strips 11 from contacting air during rotation, thereby reducing the probability of generating air bubbles in the mounting plate 9 and all the support strips 11 during rotation.

[0042] Please refer to Figures 3-5 The support bar 11 has multiple first limiting grooves 111 and multiple second limiting grooves 112 on the side away from the central axis of the mounting plate 9. The minimum distance between the first limiting groove 111 and the central axis of the mounting plate 9 is greater than the minimum distance between the second limiting groove 112 and the central axis of the mounting plate 9. All the first limiting grooves 111 and all the second limiting grooves 112 on the same support bar 11 are staggered. The first limiting grooves 111 and the second limiting grooves 112 are staggered in the circumferential direction.

[0043] The above solution aims to address the problem that, during the process of the adhesive passing through the cord fabric, due to the dense arrangement of the warp threads and the sparse arrangement of the weft threads (i.e., the small gap between adjacent warp threads, hereinafter referred to as the gap between a warp thread and its adjacent warp threads), the weft threads exert little constraint on the warp threads. This causes the adhesive to bend in some positions along the front-to-back direction as it passes through the gaps between the warp threads, increasing the gaps between the warp threads at these positions (making it easier for the adhesive to pass through the cord fabric from these positions with increased gaps). However, since the width of the cord fabric is fixed, the increased gaps in some positions will cause the adjacent warp threads to be arranged more densely (making it difficult for the adhesive to pass through the gaps between the more densely arranged warp threads), resulting in uneven contact between the adhesive and the warp threads. This solution utilizes support strip 11 to... The cord fabric provides support, and the first limiting groove 111 and the second limiting groove 112 provide individual support for adjacent warp threads to separate them. At the same time, the first limiting groove 111 and the second limiting groove 112 apply a front-to-back constraint force to the warp threads, suppressing bending in the front-to-back direction and thus maintaining the stability of the gaps between the warp threads, improving the uniformity of the contact between the adhesive and the warp threads. The distance between adjacent weft yarns in the cord fabric is greater than the distance between two adjacent support strips 11. The first limiting groove 111 is shallower than the second limiting groove 112, and the first limiting groove 111 and the second limiting groove 112 are staggered in the circumferential direction, so that the adjacent warp threads between two adjacent support strips 11 are intersected, increasing the gap between the warp threads, which facilitates the penetration of the adhesive through the cord fabric, thereby improving the efficiency of the adhesive penetrating the cord fabric.

[0044] The width and density of the first limiting groove 111 and the second limiting groove 112 in the direction of the central axis of the mounting plate 9 can be determined according to the density of the warp threads on the curtain fabric to be processed, and the width of the first limiting groove 111 and the second limiting groove 112 in the direction of the central axis of the mounting plate 9 are equal.

[0045] Please refer to Figures 3-5 It also includes: a number of support ribs 13 equal to the number of support bars 11, all of which are fixed between the mounting plate 9 and the sealing ring 12. The maximum distance between the support ribs 13 and the central axis of the mounting plate 9 is less than the minimum distance between the second limiting groove 112 and the central axis of the mounting plate 9.

[0046] In the above solution, the aim is to use the support ribs 13 to provide support for the warp threads, preventing them from bending excessively during the impact of the adhesive. At the same time, when the warp threads are not under stress, the support ribs 13 do not contact the warp threads, meaning that the support ribs 13 do not obstruct the contact between the warp threads and the adhesive. When the warp threads are deformed by the impact of the adhesive, the support ribs 13 support the warp threads, preventing the warp threads from becoming uneven again due to the increased warp thread length between adjacent support ribs 11 caused by warp thread deformation.

[0047] Please refer to Figures 1-3 It also includes: a first electric push rod 14, which is installed on the side of the housing 1 near the mounting member 8. The telescopic end of the first electric push rod 14 is fixedly connected to the mounting member 8. The height of the central axis of the mounting plate 9 is greater than the height of the central axis of the inner support roller 4, and the central axes of the two inner support rollers 4 are located in the same horizontal plane.

[0048] In the above scheme, the aim is to use the first electric push rod 14 to drive the mounting plate 9 and all the support bars 11 to move up and down, so that the worker can wrap the curtain cloth around the lower part of the cylinder formed by all the support bars 11. The height of the central axis of the mounting plate 9 is greater than the height of the central axis of the inner support roller 4, and the central axes of the two inner support rollers 4 are located in the same horizontal plane. The contact points between the two inner support rollers 4 and the mounting plate 9 and the sealing ring 12 provide support for the mounting plate 9, all the support bars 11 and the sealing ring 12, thereby improving the stability of the mounting plate 9, all the support bars 11 and the sealing ring 12 during rotation.

[0049] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 It also includes: two mounting bases 15, both fixedly connected to the housing 1, the two mounting bases 15 are rotatably connected to two rotating rollers 16, the two rotating rollers 16 are wound around a belt 17; multiple misalignment strips 18, all fixedly connected to the outside of the belt 17; the first limiting groove 111 and the second limiting groove 112 are both arc-shaped surfaces on the side near the central axis of the mounting plate 9.

[0050] In the above scheme, the aim is to use the staggered strip 18 to insert into the gap between two adjacent support strips 11, to compress and deform the curtain fabric, thereby changing the contact position between the curtain fabric and the support strip 11, so that all parts of the curtain fabric can fully contact the adhesive; the arc-shaped surfaces of the first limiting groove 111 and the second limiting groove 112 are used to reduce the probability of the warp threads being scratched by the support strip 11 when the curtain fabric moves relative to the support strip 11; the surface of the belt 17 can be provided with through holes or be made of a material that allows the adhesive to pass through, to prevent the belt 17 from blocking the curtain fabric and affecting the efficiency of the adhesive passing through the curtain fabric.

[0051] The working principle of the above scheme is as follows: When impregnating the curtain fabric with adhesive, the first electric push rod 14 is activated first. The telescopic end of the first electric push rod 14 extends and drives the mounting part 8 to move upward. The mounting part 8 drives the mounting plate 9, motor 10, all support strips 11 and sealing ring 12 to move upward together until the mounting plate 9 is completely above the two outer support rollers 5. Then the first electric push rod 14 is stopped. At this time, the worker lays the curtain fabric on the two outer support rollers 5 from right to left, and makes the curtain fabric pass through the gap between the left outer support roller 5 and the extrusion roller 7. Then the worker flattens the curtain fabric laid on the two outer support rollers 5 and activates the first electric push rod 14. The telescopic end of the first electric push rod 14... The mounting components 8, mounting plate 9, motor 10, all support bars 11, and sealing ring 12 move downward together, causing the curtain fabric to contact the lower support bars 11 in sequence. The curtain fabric between the two outer support rollers 5 bends downward under the pressure of the support bars 11. The worker releases the curtain fabric following its bending, maintaining stable tension during this period until the telescopic end of the first electric push rod 14 is reset. At this point, the mounting components 8, mounting plate 9, motor 10, all support bars 11, and sealing ring 12 are reset, and the curtain fabric contacts the inner support roller 4. The worker then starts the adhesive storage device and injects adhesive into the housing 1 until the adhesive level completely covers the mounting plate 9, at which point the injection of adhesive is temporarily stopped.

[0052] As all the support bars 11 move downward, the curtain fabric gradually wraps around the lower part of the cylinder formed by all the support bars 11. Finally, when the support bars 11 are about to return to their original position, the support bars 11 squeeze the curtain fabric and contact the adjacent misaligned bar 18. The misaligned bar 18 enters the gap between two adjacent support bars 11 and squeezes and deforms the curtain fabric in the gap.

[0053] After injecting adhesive into housing 1, the production line is started. At this time, the cord fabric moves under the traction of the subsequent winding device. The circulating pump 2, motor 10, and adhesive storage device are then started. The adhesive storage device continuously injects adhesive into housing 1 and maintains a stable adhesive level inside housing 1. Motor 10 drives the mounting plate 9, all support bars 11, and sealing ring 12 to rotate clockwise via its output shaft (the rotation perspective in this article is from front to back). The worker controls the rotation speed of the motor 10 output shaft to ensure that the linear velocity of the mounting plate 9 matches the linear velocity of the cord fabric. All support bars 11 move together with the cord fabric, which drives the inner support roller 4 to rotate. Simultaneously, the inner support roller 4 and the adjacent support bars 11 exert pressure on the cord fabric. The curtain fabric drives the belt 17 to rotate through the misalignment strip 18 in contact with it, changing the position of the curtain fabric in contact with the adjacent support strip 11 when it is on the left side of the central axis of the mounting plate 9 compared to when it is on the right side of the central axis of the mounting plate 9 (the speed at which the curtain fabric enters the device is fixed, and a mechanism to maintain the tension of the curtain fabric is provided on the left side of the device, so that when the curtain fabric is squeezed and deformed by the misalignment strip 18, the curtain fabric on the left side of the central axis of the mounting plate 9 is pulled as a whole, changing the position of the curtain fabric on the left side of the central axis of the mounting plate 9 in contact with the adjacent support strip 11), reducing the area of ​​the support strip 11 covering the curtain fabric, and allowing the adhesive to fully contact all parts of the curtain fabric.

[0054] After the circulation pump 2 is started, it delivers the adhesive above the extrusion bar 3 to the pressurization chamber, increasing the pressure of the adhesive in the pressurization chamber and driving the adhesive in the pressurization chamber through the curtain fabric and into the cylinder formed by all the support bars 11. This increases the volume of the adhesive on the inner side of the curtain fabric (i.e., the side of the curtain fabric that contacts the support bar 11). This portion of the adhesive passes through the gap between the curtain fabric and the housing 1 and enters above the extrusion bar 3 and the inner support roller 4. As the circulation pump 2 continuously draws the adhesive above the extrusion bar 3, and at the same time, new adhesive is continuously injected into the inner side of the curtain fabric, a liquid level difference appears between the inner and outer sides of the curtain fabric above the right extrusion bar 3.

[0055] After a liquid level difference appears on the inner and outer sides of the cord fabric, the inner side of the cord fabric comes into contact with the adhesive first during its entry into the device. At this time, the adhesive penetrates into the cord fabric and drives the air bubbles between the warp and weft yarns to the outer side of the cord fabric, reducing the probability of air bubbles forming on the surface of the cord fabric during the process of entering the adhesive (if both the inner and outer sides of the cord fabric come into contact with the adhesive at the same time, the gas in the gaps inside the cord fabric will not be able to escape, thus forming air bubbles on the surface of the cord fabric). This increases the contact area between the subsequent adhesive and the cord fabric, improving the impregnation efficiency of the cord fabric. The above steps are repeated until all the cord fabrics are impregnated with adhesive. At this time, the circulating pump 2, motor 10 and adhesive storage device are stopped, and the remaining adhesive in the housing 1 is recovered.

[0056] Please refer to Figure 4 and Figure 8 It also includes: a second electric push rod 19, installed on the side of the housing 1 away from the mounting part 8; a sealing element 20, which is rotatably connected to the sealing ring 12, and the support bar 11 and the mounting plate 9 are both in contact with the sealing element 20, and the sealing element 20 is provided with a rectangular through hole 201.

[0057] In the above scheme, the aim is to use the sealant 20 to suppress the flow of the adhesive, thereby increasing the pressure of the adhesive. On the one hand, this promotes the adhesive to penetrate into the warp and weft yarns of the cord fabric, and on the other hand, it promotes the expulsion of air bubbles in the gaps between the warp and weft yarns of the cord fabric, increasing the contact area between the cord fabric and the adhesive. The number of rectangular through holes 201 can be two, and the two rectangular through holes 201 are asymmetrically distributed. When one rectangular through hole 201 is blocked by an adjacent support bar 11, the other rectangular through hole 201 is located in the gap between the two adjacent support bars 11, keeping the sum of the communication areas of the two rectangular through holes 201 stable, thereby stabilizing the pressure of the adhesive in the pressurized chamber and the cylinder surrounded by the support bars 11. The sealant 20 provides support for all support bars 11, enhancing the stability of the support bars 11 during circumferential rotation.

[0058] The working principle of increasing the adhesive pressure using the sealing element 20 is as follows: After the adhesive passes through the curtain fabric from the pressurized chamber and enters the cylinder surrounded by all the support bars 11, since the lower part of the cylinder is located in the pressurized chamber, the adhesive in the cylinder can only be discharged through the rectangular through hole 201 located at the upper part. However, since the total connecting area of ​​the two rectangular through holes 201 is small, the flow rate of the adhesive when it is discharged from the rectangular through hole 201 is fast, which increases the adhesive pressure in the pressurized chamber and inside the cylinder surrounded by all the support bars 11. This increases the adhesive pressure and causes the adhesive to penetrate into the curtain fabric.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
