Description

Technical Field

[0001] The invention relates to the technical field of cord fabric production, in particular to a continuous glue dipping device for cord fabric production. Background Art

[0002] Cord fabric is a skeleton fabric for tires woven with high-strength strands as warps and medium or fine single yarns as wefts. It is named cord fabric because its warps are closely arranged and its wefts are sparsely arranged, presenting a shape similar to a cord. In the production process of cord fabric, in order to enhance the adhesion between the cord fabric and the rubber in the tire and to improve the strength and stability of the cord fabric, a continuous dipping device is required to perform a dipping operation on the cord fabric. In the process of dipping the cord fabric using a continuous dipping device, the cord fabric passes through a bath containing glue under the guidance of a roller, so that the glue in the bath contacts the side of the cord fabric and gradually penetrates into the interior of the cord fabric, thereby completely soaking the glue and wrapping the warps and wefts. However, due to the small gap between the warps and wefts of the cord fabric and the poor fluidity of the glue, it takes a long time to dip the cord fabric per unit area, resulting in a slow dipping speed of the cord fabric and low dipping efficiency of the cord fabric. Summary of the invention

[0005] Furthermore, it also includes: The two outer support rollers are both rotatably connected to the upper side of the shell, and the upper side of the shell is slidably connected to two mounting blocks, a spring is fixed between the mounting blocks and the shell, and the two mounting blocks are rotatably connected to a squeezing roller together, and the squeezing roller contacts the outer support roller on one side.

[0006] Furthermore, the mounting plate and all the support bars are completely located within the housing.

[0007] Furthermore, a plurality of first limiting grooves and a plurality of second limiting grooves are provided on a side of the support bar away from the central axis of the mounting plate.

[0008] Furthermore, the minimum distance between the first limiting groove and the central axis of the mounting disk is greater than the minimum distance between the second limiting groove and the central axis of the mounting disk, and all the first limiting grooves and all the second limiting grooves on the same support bar are staggered, and the first limiting grooves and the second limiting grooves are staggered in the circumferential direction.

[0009] Furthermore, it also includes: The supporting ribs, the number of which is equal to that of the supporting strips, are all fixedly connected between the mounting plate and the sealing ring, and the maximum distance between the supporting ribs and the central axis of the mounting plate is smaller than the minimum distance between the second limiting groove and the central axis of the mounting plate.

[0010] Furthermore, it also includes: The first electric push rod is installed on a side of the shell close to the mounting member, the telescopic end of the first electric push rod is fixedly connected to the mounting member, 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.

[0011] Furthermore, it also includes: Two mounting seats are both fixed in the housing, the two mounting seats are connected to two rotating rollers for common rotation, and the two rotating rollers are commonly wound with a belt; A plurality of offset strips are all fixedly connected to the outer side of the belt.

[0012] Furthermore, one side of the first limiting groove and the second limiting groove close to the central axis of the mounting plate are both arc-shaped surfaces.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention utilizes a circulating pump to drive the glue liquid in the shell to flow and actively pass through the gaps between the warp and weft yarns in the cord fabric, so that the glue liquid is quickly wrapped around the warp and weft yarn surfaces of the cord fabric, shortening the time required for the glue liquid to wrap the warp and weft yarns, and improving the glue dipping efficiency of the cord fabric.

[0015] The cord fabric is supported by support strips, and the first limiting groove and the second limiting groove are used to support the warp threads separately to separate adjacent warp threads.

[0018] The seal is used to inhibit the flow of the glue and increase the pressure of the glue. On the one hand, it promotes the glue to penetrate into the warp and weft yarns of the cord fabric. On the other hand, it promotes the discharge of bubbles in the gaps between the warp and weft yarns of the cord fabric, thereby increasing the contact area between the cord fabric and the glue.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0022] A continuous dipping equipment for cord fabric production, please refer to Figure 1-Figure 4 , including: a shell 1, a circulating pump 2 is installed in the shell 1, and the liquid inlet and liquid outlet of the circulating pump 2 are both connected to the inside of the shell 1; two extrusion strips 3 are fixedly connected in the shell 1, and two inner support rollers 4 are rotatably connected in the shell 1, and the inner support rollers 4 are in contact with adjacent extrusion strips 3. The liquid inlet and liquid outlet of the circulating pump 2 are respectively located on the upper and lower sides of the extrusion strips 3; a mounting member 8 is sealingly and slidably connected to the shell 1, and the mounting member 8 is sealingly and rotatably connected to the mounting plate 9, and the mounting member 8 is installed with a motor 10, and the output shaft of the motor 10 is fixedly connected to the mounting plate 9, and the mounting plate 9 is fixedly connected to the side away from the motor 10 with an annular equidistantly distributed support strips 11, and all the support strips 11 are fixedly connected to the side away from the mounting plate 9 with a sealing ring 12, and the sealing ring 12 is in contact with the shell 1; it also includes: two outer support rollers 5, both rotatably connected to the upper side of the shell 1, and two mounting blocks 6 are slidably connected to the upper side of the shell 1, a spring is fixed between the mounting block 6 and the shell 1, and the two mounting blocks 6 are rotatably connected with an extrusion roller 7, and the extrusion roller 7 is in contact with the outer support roller 5 on one side; the mounting plate 9 and all the support strips 11 are completely located in the shell 1.

[0023] The above scheme aims to solve the problem of low efficiency of cord fabric dipping in the existing process of cord fabric dipping due to small pores of the cord fabric and poor fluidity of the glue. The scheme uses a circulating pump 2 to drive the glue in the shell 1 to flow and pass through the gaps between the warp and weft yarns of the cord fabric, so that the glue is quickly wrapped around the warp and weft yarn surfaces of the cord fabric, thereby improving the efficiency of cord fabric dipping. All support bars 11 are cylindrical, and the outer diameter of the cylinder is equal to the outer diameter of the mounting plate 9 and the sealing ring 12. The shell 1, two extrusion bars 3, two inner support rollers 4 and the lower part of the cylinder formed by all support bars 11 together constitute a pressurized chamber. The inner support roller 4 is used to guide the cord fabric to fit to the surface of the cylinder formed by all support bars 11, and the part of the cord fabric entering the pressurized chamber is supported by adjacent support bars 11.

[0024] The shell 1 is connected to an external glue storage device. When the cord fabric is dipped in glue, the glue storage device continuously injects glue into the shell 1 to keep the amount of glue in the shell 1 stable; the inner support roller 4 can be made of elastic rubber material, and the mounting plate 9 and the sealing ring 12 are in contact with the inner support roller 4. The cord fabric is squeezed between the inner support roller 4 and the adjacent support bar 11 during the dipping process. The inner support roller 4 and the adjacent support bar 11 are used to squeeze the cord fabric, so that the bubbles adhered to the surface of the cord fabric warp and weft yarn are separated from the cord fabric, reducing the content of bubbles in the glue in the pressurized chamber, thereby improving the dipping effect of the cord fabric; the liquid inlet of the circulating pump 2 can be installed with an inclined setting The filter cloth can reduce the bubbles in the glue liquid from entering the circulation pump 2, thereby reducing the volume of the bubbles in the pressurized chamber; the squeezing roller 7 and the outer supporting roller 5 on the left are used to clamp the cord fabric to squeeze out the excess glue on the surface of the cord fabric; the sealing ring 12 is used to provide support for the rear end of the support bar 11 to improve the strength of the support bar 11; the mounting plate 9 and all the support bars 11 are located in the shell 1, so that the glue liquid in the shell 1 can completely cover the mounting plate 9 and all the support bars 11, avoiding the mounting plate 9 and all the support bars 11 from contacting with the air during rotation, thereby reducing the probability of bubbles generated by the mounting plate 9 and all the support bars 11 during rotation.

[0025] Please refer to Figure 3-Figure 5 A plurality of first limiting grooves 111 and a plurality of second limiting grooves 112 are provided on the side of the support bar 11 away from the central axis of the mounting disk 9; the minimum distance between the first limiting groove 111 and the central axis of the mounting disk 9 is greater than the minimum distance between the second limiting groove 112 and the central axis of the mounting disk 9, and all the first limiting grooves 111 and all the second limiting grooves 112 on the same support bar 11 are staggered, and the first limiting grooves 111 and the second limiting grooves 112 are staggered in the circumferential direction.

[0026] In the above scheme, the purpose is to solve the problem that in the process of glue passing through the cord fabric, the warp yarns of the cord fabric are closely arranged, and the weft yarns are sparsely arranged, that is, the gap between two adjacent warp yarns (hereinafter referred to as the gap between the warp yarns to refer to the gap between the warp yarns and the adjacent warp yarns) is small, and the constraint force of the weft yarns on the warp yarns is small, so that in the process of glue passing through the gap between the warp yarns, the glue squeezes the warp yarns at some positions and bends them in the front-to-back direction, thereby increasing the gap between the warp yarns at the above positions (the glue can more easily pass through the cord fabric from the position where the gap between the warp yarns increases). However, since the width of the cord fabric is fixed, the increase in the gap between the warp yarns at some positions will make the warp yarns at the adjacent positions more closely arranged (it is difficult for the glue to pass through the gap between the warp yarns that are more closely arranged), so that the glue cannot evenly contact the warp yarns. In this scheme, the support strips 11 are used to support the cord fabric. The cord fabric is supported, and the first limiting groove 111 and the second limiting groove 112 are used to separately support adjacent warps to separate the adjacent warps. At the same time, the first limiting groove 111 and the second limiting groove 112 are used to apply a restraining force in the front-to-back direction to the warps to suppress the bending of the warps in the front-to-back direction, thereby maintaining the stability of the gaps between the warps and improving the uniformity of the contact between the glue and the warps; 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 two warps between the two adjacent support strips 11 are cross-distributed, and the gap between the warps is increased, which is conducive to the glue passing through the cord fabric, thereby improving the efficiency of the glue penetrating the cord fabric.

[0027] The width and density of the first limiting groove 111 and the second limiting groove 112 in the central axis direction of the mounting disk 9 can be determined according to the density of the warp threads on the cord fabric to be processed, and the widths of the first limiting groove 111 and the second limiting groove 112 in the central axis direction of the mounting disk 9 are equal.

[0028] Please refer to Figure 3-Figure 5 , and also includes: support ribs 13, the number of which is equal to that of the support bars 11, all of which are fixed between the mounting plate 9 and the sealing ring 12, and the maximum distance between the support ribs 13 and the central axis of the mounting plate 9 is smaller than the minimum distance between the second limiting groove 112 and the central axis of the mounting plate 9.

[0029] In the above scheme, the support ribs 13 are used to provide support for the warp threads to prevent the warp threads from excessively bending during the impact of the glue liquid. At the same time, when the warp threads are not subjected to force, the support ribs 13 do not contact the warp threads, that is, the support ribs 13 do not hinder the contact between the warp threads and the glue liquid. When the warp threads are deformed by the impact of the glue liquid, the support ribs 13 support the warp threads to prevent the warp threads from deforming, thereby increasing the length of the warp threads between adjacent support bars 11 and causing the warp threads to reappear in the above-mentioned uneven warp thread gap problem.

[0030] Please refer to Figure 1-Figure 3 , and also includes: a first electric push rod 14, which is installed on one side of the shell 1 close to 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.

[0031] In the above scheme, the first electric push rod 14 is used to drive the mounting plate 9 and all the support bars 11 to move up and down, so that workers can wind the cord fabric around the lower part of the cylinder surrounded 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, and the contact points of the two inner support rollers 4 with the mounting plate 9 and the sealing ring 12 are used to 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.

[0032] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 , and also includes: two mounting seats 15, both fixedly connected to the shell body 1, the two mounting seats 15 are connected to two rotating rollers 16 for common rotation, and the two rotating rollers 16 are commonly wound with a belt 17; a plurality of offset strips 18, all fixedly connected to the outer side of the belt 17; the first limiting groove 111 and the second limiting groove 112 are both arc-shaped surfaces on one side close to the central axis of the mounting plate 9.

[0033] In the above scheme, the purpose is to use the offset strip 18 to penetrate into the gap between two adjacent support strips 11, squeeze and deform the cord fabric, and then change the contact position between the cord fabric and the support strip 11, so that all parts of the cord fabric can be fully in contact with the glue; the arc surface of the first limiting groove 111 and the second limiting groove 112 is used to reduce the probability of the warp thread being scratched by the support strip 11 when the cord fabric moves relative to the support strip 11; the surface of the belt 17 can be provided with a through hole or it can be made of a material through which the glue can pass, so as to prevent the belt 17 from blocking the cord fabric and affecting the efficiency of the glue passing through the cord fabric.

[0034] The working principle of the above scheme is as follows: when the cord fabric is dipped in glue, the first electric push rod 14 is first started, the telescopic end of the first electric push rod 14 extends out and drives the mounting member 8 to move up, and the mounting member 8 drives the mounting plate 9, the motor 10, all the support bars 11 and the sealing ring 12 to move up together, until the mounting plate 9 is completely located above the two outer support rollers 5, the first electric push rod 14 is stopped, and at this time the worker lays the cord fabric on the two outer support rollers 5 from right to left, and makes the cord fabric pass through the gap between the outer support roller 5 on the left and the squeezing roller 7, and then the worker flattens the cord fabric laid on the two outer support rollers 5, and starts the first electric push rod 14, the telescopic end of the first electric push rod 14 The mounting member 8, mounting plate 9, motor 10, all support strips 11 and sealing ring 12 are driven to move downward together, so that the cord fabric contacts the lower support strip 11 in turn, and the cord fabric between the two outer support rollers 5 bends downward under the pressure of the support strip 11. The worker releases the cord fabric following the bending of the cord fabric, and keeps the tension of the cord fabric stable during this period until the telescopic end of the first electric push rod 14 is reset, and the mounting member 8, mounting plate 9, motor 10, all support strips 11 and sealing ring 12 are reset, and the cord fabric contacts the inner support roller 4 at the same time. Then the worker starts the glue storage equipment and injects glue into the shell 1 until the liquid level of the glue completely covers the mounting plate 9, and temporarily stops the injection of glue.

[0035] As all the support bars 11 move downward, the cord fabric gradually wraps the lower part of the cylinder formed by all the support bars 11. Finally, when the support bars 11 are about to be reset, the support bars 11 squeeze the cord fabric and contact the adjacent offset bars 18. The offset bars 18 enter the gap between two adjacent support bars 11 and squeeze and deform the cord fabric in the gap.

[0036] After the glue is injected into the shell 1, the production line is started. At this time, the cord fabric moves under the traction of the subsequent winding device. At this time, the circulation pump 2, the motor 10 and the glue storage device are started. The glue storage device continues to inject glue into the shell 1 and maintains the stability of the glue liquid level in the shell 1; the motor 10 drives the installation disk 9, all the support bars 11 and the sealing ring 12 to rotate clockwise through the output shaft (the rotation perspective of this article is from front to back). At this time, the worker controls the speed of the output shaft of the motor 10 to make the linear speed of the installation disk 9 consistent with the linear speed of the cord fabric, all the support bars 11 move together with the cord fabric, and the cord fabric drives the inner support roller 4 to rotate. At the same time, the inner support roller 4 and the adjacent support bars 11 give the cord fabric extrusion force. The cord fabric drives the belt 17 to rotate through the offset strip 18 in contact with it, so that the position where the cord fabric contacts the adjacent support strip 11 when it is on the left side of the central axis of the installation disk 9 is changed from the position where the cord fabric contacts the adjacent support strip 11 when it is on the right side of the central axis of the installation disk 9 (the speed at which the cord fabric enters the device is fixed, and a mechanism for maintaining the tension of the cord fabric stable is provided on the left side of the device, so that when the cord fabric is squeezed and deformed by the offset strip 18, the cord fabric on the left side of the central axis of the installation disk 9 is pulled as a whole, so that the position where the cord fabric on the left side of the central axis of the installation disk 9 contacts the adjacent support strip 11 is changed), reducing the shielding area of ​​the support strip 11 on the cord fabric, so that the glue is in full contact with all parts of the cord fabric.

[0037] After the circulation pump 2 is started, the circulation pump 2 transports the glue above the extrusion strip 3 to the pressurized chamber, thereby increasing the pressure of the glue in the pressurized chamber, and driving the glue in the pressurized chamber to pass through the cord fabric and enter the cylinder surrounded by all the support strips 11, thereby increasing the volume of the glue on the inner side of the cord fabric (i.e., the side where the cord fabric contacts the support strips 11). This part of the glue passes through the gap between the cord fabric and the shell 1 and the cord fabric and enters above the extrusion strip 3 and the inner support roller 4. Since the circulation pump 2 continuously extracts the glue above the extrusion strip 3 and new glue is continuously injected into the inner side of the cord fabric, a liquid level difference appears on the inner and outer sides of the cord fabric above the right extrusion strip 3.

[0038] After a liquid level difference appears on the inner and outer sides of the cord fabric, the inner side of the cord fabric first contacts with the glue when the cord fabric enters the device. At this time, the glue penetrates into the cord fabric and drives the bubbles between the warp and weft yarns in the cord fabric to the outside of the cord fabric, thereby reducing the probability of bubbles forming on the surface of the cord fabric when the cord fabric enters the glue (if the inner and outer sides of the cord fabric contact with the glue at the same time, the gas in the internal gap of the cord fabric cannot be discharged, and bubbles are formed on the surface of the cord fabric), thereby increasing the contact area between the subsequent glue and the cord fabric, and improving the glue dipping efficiency of the cord fabric; repeat the above steps until all the cord fabrics are dipped in glue, at which time the circulating pump 2, the motor 10 and the glue storage device are stopped, and the remaining glue in the shell 1 is recovered.

[0039] Please refer to Figure 4 and Figure 8 , further comprising: a second electric push rod 19, mounted on a side of the housing 1 away from the mounting member 8; a sealing member 20, sealingly rotatably connected to the sealing ring 12, the support bar 11 and the mounting plate 9 are both in contact with the sealing member 20, and a rectangular through hole 201 is provided on the sealing member 20.

[0040] In the above scheme, the purpose is to use the seal 20 to inhibit the flow of the glue liquid, thereby increasing the pressure of the glue liquid, on the one hand, to promote the glue liquid to penetrate into the warp and weft yarns of the cord fabric, and on the other hand, to promote the discharge of bubbles in the gaps between the warp and weft yarns of the cord fabric, thereby increasing the contact area between the cord fabric and the glue liquid; the number of rectangular through holes 201 can be two, and the two rectangular through holes 201 are asymmetrically distributed. When one of the rectangular through holes 201 is blocked by the adjacent support bar 11, the other rectangular through hole 201 is located in the gap between the two adjacent support bars 11, so as to keep the sum of the connecting areas of the two rectangular through holes 201 stable, thereby stabilizing the pressure of the glue liquid in the pressurized chamber and the cylinder surrounded by the support bars 11; the seal 20 provides support for all support bars 11, thereby enhancing the stability of the support bars 11 during circumferential rotation.

[0041] The working principle of increasing the pressure of the glue liquid by using the sealing member 20 is as follows: after the glue liquid passes through the cord fabric from the pressurized chamber and enters the cylinder surrounded by all the support strips 11, since the lower part of the cylinder is located in the pressurized chamber, the glue liquid in the cylinder can only be discharged through the rectangular through hole 201 located at the upper part thereof. However, since the total connecting area of ​​the two rectangular through holes 201 is small, the flow rate of the glue liquid when being discharged from the rectangular through hole 201 is fast, causing the pressure of the glue liquid in the pressurized chamber and the cylinder surrounded by all the support strips 11 to increase, thereby increasing the pressure of the glue liquid and causing the glue liquid to penetrate into the cord fabric.

[0042] The above shows and describes 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, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
