Abstract
Description
Technical Field
[0001] This invention relates to the field of tire production equipment, and more specifically, to a cord trimming device and a steel cord processing system. Background Technology
[0002] In the manufacturing process of engineering tires and giant radial tires used in mining engineering machinery, steel cord fabric tire carcass is one of the important components. The production of engineering tires and giant tire steel cord fabric tire carcasses requires cutting calendered steel cord fabric to the required angle and width, and then splicing and winding it for forming and use.
[0003] The edges of calendered steel cord fabric are often not perfectly aligned with the joint requirements, leading to problems such as excessively large cord spacing or insufficient joint strength. Typically, the calendered fabric needs to be trimmed after the cutting process to meet the joint requirements.
[0004] The traditional cold trimming technique using disc cutters to remove excess adhesive from the fabric is as follows: Currently, the thickness of traditional all-steel and semi-steel tire cord fabric is typically between 1mm and 4mm. This method involves using a torque motor to drive the disc cutters on both sides of the fabric, pressing them against the edge to trim away the excess adhesive. However, this method is only suitable for trimming traditional all-steel and semi-steel tire cord fabric, which is typically 1mm to 4mm thick. Thinner fabrics have smaller wire spacing. In contrast, engineering and large-scale tire cord fabrics are typically 3mm to 13mm thick, with larger wire spacing. Using a torque motor-driven disc cutter results in inconsistent amounts of excess adhesive after trimming, and the amount of adhesive residue cannot consistently meet the requirement of half the wire spacing.
[0005] Therefore, the existing technology suffers from poor edge trimming effect of giant steel wire cord fabric. Summary of the Invention
[0006] The main objective of this invention is to provide a fabric trimming device and a steel wire fabric processing system to solve the problem of poor trimming effect of giant steel wire fabric in the prior art.
[0007] To achieve the above objectives, according to one aspect of the present invention, a curtain trimming device is provided, comprising: an installation assembly; a positioning assembly disposed on the installation assembly, at least a portion of the positioning assembly being movable relative to the installation assembly, and the positioning assembly having a positioning channel for the curtain to pass through; and a cutting assembly disposed on the installation assembly, wherein, in the direction of movement of the curtain, the cutting assembly is located downstream of the positioning assembly and cuts the curtain passing through the positioning channel, and the cutting assembly is capable of cutting the curtain from both sides in the thickness direction of the curtain.
[0008] Furthermore, the positioning assembly includes at least two sets of opposing roller groups, each set of roller groups having multiple rollers, and a positioning channel between the two sets of opposing roller assemblies.
[0009] Furthermore, the axial direction of the rollers is the same as the width direction of the fabric; and / or the number of rollers in each roller group is the same.
[0010] Furthermore, at least three of the rollers in the two sets of rollers arranged opposite each other have a first positioning protrusion or a second positioning protrusion on their circumferential sidewalls, and there is a positioning gap between the first positioning protrusion and the second positioning protrusion in the width direction of the fabric.
[0011] Furthermore, the positioning component also includes a first driving component, which is connected to a roller having a first positioning protrusion or a second positioning protrusion and drives the roller to move axially to adjust the distance between the first positioning protrusion and the second positioning protrusion.
[0012] Furthermore, the roller assembly consists of two groups, each group having three rollers. In one group, the rollers on both sides have a first positioning protrusion, and the roller in the middle has a second positioning protrusion. The positioning assembly also includes a first driving assembly, which is drivenly connected to the roller with the second positioning protrusion to adjust the distance between the first and second positioning protrusions.
[0013] Furthermore, the positioning component includes a second drive component, which is drivenly connected to at least one of the two opposing sets of rollers to cause the two opposing sets of rollers to move in a direction that moves closer to or further away from each other.
[0014] Furthermore, the positioning assembly includes a positioning plate, which is L-shaped and includes a first section and a second section connected in sequence. The first section is connected to the mounting assembly, and all the roller assemblies are mounted on the second section.
[0015] Furthermore, the cutting assembly includes a first cutting part and a second cutting part arranged opposite to each other, the first cutting part and the second cutting part meshing with each other and cutting the curtain fabric from both sides of the curtain fabric respectively.
[0016] Furthermore, the mounting assembly includes: a mounting plate having a slide rail; a connecting plate movably mounted on the mounting plate and capable of moving along the slide rail, a positioning assembly and a cutting assembly respectively mounted on the connecting plate; and a third drive assembly drivenly connected to the connecting plate.
[0017] Furthermore, the fabric trimming device also includes an adhesive edge guide assembly, which is located downstream of the cutting assembly, and at least a portion of the adhesive edge guide assembly is connected to the connecting plate.
[0018] According to another aspect of the present invention, a steel wire cord fabric processing system is provided, including a frame, wherein the above-mentioned cord fabric trimming device is respectively provided on both sides of the frame.
[0019] Applying the technical solution of this invention, the curtain trimming device in this application includes an installation component, a positioning component, and a cutting component.

[0020] When using the fabric trimming device of this application, since the device has an installation component, it can be installed at the location where the fabric passes through, thereby achieving side cutting of the fabric. Furthermore, since the device also has a positioning component, when the fabric passes through the positioning channel of the positioning component, the positioning component can adjust the position of the fabric, thereby changing the relative position between the fabric and the cutting component. This allows for adjustment of the cutting position of the cutting component, ensuring that the fabric trimming device of this application can flexibly cut the sides of the fabric. Simultaneously, since the cutting component of this application can cut the fabric from both sides along its thickness direction, the cutting thickness of the fabric trimming device can meet the requirements of giant steel wire fabrics. Therefore, the fabric trimming device of this application effectively solves the problem of poor trimming effect of giant steel wire fabrics in the prior art.
[0021] Furthermore, since the steel cord fabric processing system of this application has the aforementioned fabric trimming device on both sides of the frame, the steel cord fabric processing system of this application can trim both sides of the giant steel cord fabric at the same time.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] To address the problem of poor edge trimming effect in existing technologies for giant steel wire cord fabrics, this application provides a cord trimming device and a steel wire cord fabric processing system.
[0035] And, as Figure 4 and Figure 5 As shown, the steel wire cord fabric processing system of this application includes a frame 50, and the following cord fabric trimming devices 60 are respectively provided on both sides of the frame 50.
[0036] like Figures 1 to 6 As shown, the curtain trimming device of this application includes an mounting assembly 10, a positioning assembly 20, and a cutting assembly 30. The positioning assembly 20 is disposed on the mounting assembly 10, at least a portion of the positioning assembly 20 is movable relative to the mounting assembly 10, and the positioning assembly 20 has a positioning channel for the curtain to pass through; the cutting assembly 30 is disposed on the mounting assembly 10, and in the direction of movement of the curtain, the cutting assembly 30 is located downstream of the positioning assembly 20 and cuts the curtain passing through the positioning channel, and the cutting assembly 30 is capable of cutting the curtain from both sides in the thickness direction of the curtain.
[0037] When using the fabric trimming device of this application, since the fabric trimming device has an installation component 10, the fabric trimming device can be installed at the position where the fabric 600 passes through, thereby achieving the cutting of the side edge of the fabric 600. Furthermore, since the fabric trimming device also has a positioning component 20, when the fabric passes through the positioning channel of the positioning component 20, the positioning component 20 can adjust the position of the fabric, thereby changing the relative position of the fabric and the cutting component 30, and thus adjusting the cutting position of the cutting component 30 on the fabric, ensuring that the fabric trimming device of this application can flexibly cut the side edge of the fabric. Simultaneously, since the cutting component 30 of this application can cut the fabric from both sides in the thickness direction of the fabric, the cutting thickness of the fabric trimming device of this application can meet the thickness of the giant steel wire fabric. Therefore, the fabric trimming device of this application effectively solves the problem of poor trimming effect of giant steel wire fabric in the prior art.
[0038] In one specific embodiment of this application, the fabric trimming device is mounted on the frame 50 of the wire cord fabric processing system via mounting assembly 10.
[0039] Furthermore, in Figure 4 In the illustrated embodiment, since the frame 50 of the steel cord fabric processing system in this application is provided with the above-mentioned fabric trimming device 60 on both sides, the steel cord fabric processing system in this application can trim both sides of the giant steel cord fabric at the same time.
[0040] Specifically, in Figures 1 to 3In the illustrated embodiment, the positioning component 20 includes at least two sets of opposing roller groups 21, each roller group 21 having multiple rollers 211, and a positioning channel between the two opposing roller groups 21. In this application, because the conveying device transporting the curtain fabric does not transport it horizontally during the fabric cutting process, but rather vertically or approximately vertically, the curtain fabric moves vertically or approximately vertically when passing through the fabric trimming device. Therefore, by setting at least two sets of opposing roller groups 21, the movement direction of the curtain fabric can be limited on both sides, thereby ensuring the stability of the cutting component 30 when cutting the curtain fabric. Furthermore, since the roller group 21 has multiple rollers 211, the rollers 211 can rotate relative to the curtain fabric when it passes through the positioning channel, effectively reducing the resistance of the curtain fabric when passing through the positioning channel.
[0041] Furthermore, the two sets of rollers 21 arranged opposite to each other in this application can also support the fabric.
[0042] Optionally, the axial direction of roller 211 is the same as the width direction of the fabric. This arrangement further ensures the positioning effect of the roller assembly on the fabric, guaranteeing that the fabric can move in a preset direction. Simultaneously, this arrangement also effectively reduces the resistance between the rollers and the fabric, thereby ensuring the stable operation of the fabric trimming device.
[0043] Optionally, in Figures 1 to 3 In the illustrated embodiment, each roller group 21 has the same number of rollers 211. This arrangement effectively ensures the stability of the curtain fabric as it passes through the positioning channel, guaranteeing more uniform force distribution on the fabric.
[0044] Specifically, at least three of the rollers 211 in the two opposing roller groups 21 have a first positioning protrusion 212 or a second positioning protrusion 213 on their circumferential sidewalls, and a positioning gap exists between the first positioning protrusion 212 and the second positioning protrusion 213 in the width direction of the fabric. Furthermore, the positioning assembly 20 also includes a first driving assembly 22, which is connected to and drives the rollers 211 with the first positioning protrusion 212 or the second positioning protrusion 213 to move axially, thereby adjusting the distance between the first positioning protrusion 212 and the second positioning protrusion 213. In this embodiment, the total number of first positioning protrusions 212 and second positioning protrusions 213 is at least three, thereby enabling linear positioning of the fabric through all the first positioning protrusions 212 and second positioning protrusions 213, thus ensuring that the fabric can move in a preset direction. Meanwhile, since there is a positioning gap between the first positioning protrusion 212 and the second positioning protrusion 213, the steel wire 610 inside the curtain can be clamped by the first positioning protrusion 212 and the second positioning protrusion 213. At the same time, by changing the steel wire 610 clamped by the first positioning protrusion 212 and the second positioning protrusion 213, the relative position between the positioning component 20 and the curtain can be adjusted, thereby adjusting the relative position between the cutting component 30 and the curtain, and thus changing the cutting position of the cutting component 30 on the curtain, so that the curtain trimming device in this application can trim the curtain to different degrees.
[0045] In other words, in this application, the first positioning protrusion 212 and the second positioning protrusion 213 are located at different positions along the length of the curtain in the direction the curtain travels. The line connecting all the first positioning protrusions 212 is parallel to the direction of curtain travel, and the line connecting all the second positioning protrusions 213 is also parallel to the direction of curtain travel. By driving the first positioning protrusion 212 or the second positioning protrusion 213 through the first driving component 22, the positioning gap between the first positioning protrusion 212 and the second positioning protrusion 213 can be changed, thereby ensuring that the first positioning protrusion 212 and the second positioning protrusion 213 can clamp the steel wire inside the curtain, thereby achieving position adjustment or limiting of the curtain. In this application, by selecting the steel wire clamped by the first positioning protrusion 212 and the second positioning protrusion 213, the position of the curtain can be adjusted. And after the first positioning protrusion 212 and the second positioning protrusion 213 clamp the selected steel wire, the curtain can be limited.
[0046] In one specific embodiment of this application, such as Figures 1 to 3As shown, the roller group 21 consists of two groups, each with three rollers 211. In one group, the rollers on either side have first positioning protrusions 212, and the middle roller has a second positioning protrusion 213. The positioning assembly 20 also includes a first driving assembly 22, which is drivenly connected to the roller 211 with the second positioning protrusion 213 to adjust the distance between the first positioning protrusions 212 and the second positioning protrusions 213. In this embodiment, the two first positioning protrusions 212 and the one second positioning protrusion 213 of the three rollers 211 form a staggered "V"-shaped protrusion, used to embed into both sides of a single steel wire near the edge of the curtain fabric, preferably the second steel wire at the outermost edge of the curtain fabric. By driving the second positioning protrusion 213, the curtain fabric is slowly clamped to achieve a positioning and guiding function.
[0047] Specifically, such as Figures 1 to 3 As shown, the positioning component 20 includes a second driving component 24, which is drivenly connected to at least one of two opposing sets of roller groups 21, causing the two opposing sets of roller groups 21 to move in directions that bring them closer together or further apart. This configuration enables the positioning component 20 to position fabrics of different thicknesses. In other words, when the thickness of the fabric to be trimmed is different, the second driving component 24 can drive the roller groups 21, ensuring that the positioning channel of the positioning component 20 is adapted to the thickness of the fabric to be trimmed. Specifically, in this application, by setting the second driving component 24 to drive the roller groups 21, the size of the positioning channel, specifically the size of the positioning channel corresponding to the thickness direction of the fabric to be trimmed, is adjusted.
[0048] Optionally, such as Figure 3 As shown, the positioning component 20 includes a positioning plate 23, which is L-shaped and includes a first section and a second section connected in sequence. The first section is connected to the mounting component 10, and all the roller groups 21 are disposed on the second section. That is, in this application, the positioning component 20 is mounted on the mounting component 10 via the positioning plate 23, and the first section of the positioning plate 23 is used to connect with the mounting component 10, while the second section of the positioning plate 23 is used to set the roller groups 21. The purpose of setting the positioning plate 23 in an L-shape is to reduce interference between the roller groups 21 and the mounting component 10 during use, thereby ensuring the stable operation of the fabric trimming device.
[0049] Specifically, the cutting assembly 30 includes a first cutting section 31 and a second cutting section 32 disposed opposite to each other. The first cutting section 31 and the second cutting section 32 mesh with each other and cut the curtain fabric from both sides respectively. Of course, in this application, the structural form of the first cutting section 31 and the second cutting section 32 can be adjusted to at least ensure that the cutting assembly 30 can simultaneously cut both sides of the curtain fabric in the thickness direction through the first cutting section 31 and the second cutting section 32 respectively. Preferably, the first cutting section 31 and the second cutting section 32 each have a circular blade disc.
[0050] In one specific embodiment of this application, the mounting assembly 10 includes a mounting plate 11 and a connecting plate 13. The mounting plate 11 has a slide rail 12; the connecting plate 13 is movably mounted on the mounting plate 11 and can move along the slide rail 12; the positioning assembly 20 and the cutting assembly 30 are respectively mounted on the connecting plate 13; a third driving assembly 14 is drivenly connected to the connecting plate 13. With this configuration, the connecting plate 13 can drive the positioning assembly 20 and the cutting assembly 30 to move together, thereby changing the relative positions of the positioning assembly 20 and the cutting assembly 30 with the curtain fabric, thus changing the trimming position of the curtain fabric, and thereby adjusting the amount of trimming adhesive, ensuring that the amount of trimming adhesive residue meets the requirement of controlling the amount of adhesive residue at half the wire spacing for different wire densities. Furthermore, it should be noted that in this application, the cutting portion of the curtain fabric cut by the cutting assembly 30 is a portion of the curtain fabric passing through the positioning channel.
[0051] Optionally, the fabric trimming device further includes an edge guide assembly 40, which is located downstream of the cutting assembly 30, and at least a portion of the edge guide assembly 40 is connected to the connecting plate 13. This arrangement allows the edge guide assembly 40 to separate the cut fabric edge material from the fabric.
[0052] Optionally, the adhesive edge discharge assembly 40 includes: at least one discharge roller rotatably connected to the connecting plate 13; a conveyor belt located downstream of the discharge roller and capable of conveying the cut material edge; and a collection hopper located below the conveyor belt and capable of receiving the adhesive edge 630 conveyed by the conveyor belt. Of course, in this application, a conveyor belt may not be provided, so that the material edge is directly collected by the collection hopper after being discharged by the discharge roller.
[0053] The third drive assembly 14 includes: a lead screw; a nut seat, which is fixedly connected to one end of a support plate and rotatably connected to the lead screw, and is movable along the lead screw; and a drive unit, which is connected to one end of the lead screw and is capable of driving the lead screw to rotate. In this application, the forms of the first drive assembly 22 and the second drive assembly 24 can be flexibly adjusted, as long as the first drive assembly 22 can drive the roller 211 and the second drive assembly 24 can drive the roller group 21. That is, in this application, the first drive assembly 22 and the second drive assembly 24 can be a drive motor, a drive cylinder, or a drive structure that drives the lead screw and nut, etc.
[0054] In this application, the steel cord fabric processing system also includes a guide device 200, which guides the steel cord fabric roll 400 open and peels off the padding fabric and winds it onto the roll via a padding fabric winding device 300. The peeled fabric is then actively conveyed to the fabric trimming device position via a fabric guide pull-out roller mechanism 70, and then the fabric tensioning assembly 80 tensions the fabric and conveys it to the storage arc position. Simultaneously, the trimmed adhesive edge 630 is discharged by the adhesive edge guide assembly 40 for recycling. Thick trimmed fabric is pulled to a fixed length by a clamp pulling device 90 and cut to a fixed length by a cutting main unit 100. The cut fabric strips are conveyed to a splicing joint device by a cutting conveyor belt device 500 for splicing and winding.
[0055] like Figure 6 The diagram shows a process for trimming the fabric. The fabric 600 is composed of multiple parallel steel wires 610 and rubber 620, which are calendered with adhesive using a calendering machine. Let the spacing between the steel wires be 'a'. To ensure that the spacing between the steel wires is as close to the same as possible after the two fabrics are joined, the relative positions of the positioning component 20 and the cutting component 30 are adjusted to achieve an excess adhesive thickness of 1 / 2 'a' for the required trimming thickness.
[0056] From the above description, it can be seen that the embodiments of the present invention achieve the following technical effects: When using the curtain trimming device of this application, since the curtain trimming device has an installation component 10, the curtain trimming device can be installed at the position where the curtain passes through through the installation component 10, thereby realizing the cutting of the side edge of the curtain. Furthermore, since the curtain trimming device also has a positioning component 20, when the curtain passes through the positioning channel of the positioning component 20, the positioning component 20 can adjust the position of the curtain, thereby changing the relative position of the curtain and the cutting component 30, and thus adjusting the cutting position of the cutting component 30 on the curtain, ensuring that the curtain trimming device of this application can flexibly cut the side edge of the curtain. Simultaneously, since the cutting component 30 of this application can cut the curtain from both sides in the thickness direction of the curtain, the cutting thickness of the curtain trimming device of this application can meet the thickness of the giant steel wire curtain. Therefore, the curtain trimming device of this application effectively solves the problem of poor trimming effect of giant steel wire curtain in the prior art.
