Description

Technical Field

[0001] This invention relates to the field of rubber processing and production, and more specifically, to a rubber conveying device and a rubber compounding device. Background Technology

[0002] In the processing and production of wound materials, especially in the manufacturing of flexible materials such as films and sheets, the beginning and end of the sprue often become critical links that hinder production line efficiency and product quality. Due to their flexibility and stickiness, these materials are highly susceptible to wrinkles and folds caused by gravity and speed differences as they fall from the conveyor belt to the winding device. Folds not only damage the integrity of the film, rendering it irreversible waste, but also disrupt the continuous winding process, forcing the production line to stop for manual intervention or cleaning, which undoubtedly significantly reduces production efficiency. More importantly, each fold at the beginning or end of the sprue wastes a certain length of high-quality film, directly increasing production costs. Summary of the Invention

[0003] The main objective of this invention is to provide a rubber material conveying device and a rubber material compounding device to solve the problem in the prior art that the tail of the rubber material is easily folded and waste is generated when the winding process is about to be completed.

[0004] To achieve the above objectives, according to one aspect of the present invention, a rubber material conveying device is provided, comprising a transverse conveying assembly for transversely conveying rubber material, an infeed roller, and a movable roller. Along the conveying direction of the rubber material, the infeed roller is located downstream of the transverse conveying assembly. The movable roller is movably disposed relative to the transverse conveying assembly and has a clearance position for avoiding the conveying path of the rubber material and a working position for moving into the conveying path of the rubber material. When the movable roller is in the clearance position, the rubber material sequentially passes through the transverse conveying assembly and the infeed roller to enter the roll assembly to form a roll. When the movable roller is in the working position, the movable roller is located between the transverse conveying assembly and the infeed roller and pushes the rubber material downward. The rubber material sequentially passes through the bottom surface of the movable roller and the top surface of the infeed roller before entering the roll assembly.

[0005] Furthermore, the rubber material conveying device also includes a second conveying roller. When the movable roller is in the working position, the second conveying roller is farther away from the infeed roller than the movable roller. When the tail of the rubber material is conveyed to the movable roller, the tail falls to the second conveying roller.

[0006] Furthermore, the movable roller is located below the transverse conveyor assembly, and the movable roller is rotatable relative to the transverse conveyor assembly.

[0007] Furthermore, the rubber material conveying device also includes: a swing arm and a swing drive, the swing arm is connected to the movable roller, and the swing arm is rotatably mounted on the transverse conveying assembly; the swing drive is driven to the swing arm and drives the swing arm to switch the movable roller between the avoidance position and the working position.

[0008] Furthermore, the transverse conveying assembly includes a plurality of first conveying rollers, which are spaced apart and arranged laterally. Along the arrangement direction of the first conveying rollers, each first conveying roller sequentially conveys the rubber material.

[0009] Furthermore, at least one first conveying roller includes a plurality of rollers, the arrangement direction of each roller being perpendicular to the arrangement direction of each first conveying roller, and the axial direction of each roller being perpendicular to the arrangement direction of each first conveying roller.

[0010] Furthermore, the transverse conveying assembly also includes a transverse drive component, which is driven to connect with each of the first conveying rollers. When conveying the rubber material, the transverse drive component drives each of the first conveying rollers to move laterally into the falling path of the rubber material. The transverse direction of the first conveying rollers is consistent with the arrangement direction of each of the first conveying rollers.

[0011] Furthermore, the transverse conveying assembly also includes a frame and a slider. The frame has a guide rail extending along the arrangement direction of each of the first conveying rollers. The slider is connected to each of the first conveying rollers and is slidably disposed within the guide rail. The slider can drive each of the first conveying rollers to move along the extension direction of the guide rail.

[0012] Furthermore, the transverse conveying assembly also includes a rotatably mounted guide roller, and there is a gap between the guide roller and the first conveying roller for the rubber material to pass through. The rubber material passes through each of the first conveying rollers in sequence and then leaves the transverse conveying assembly through the gap.

[0013] According to another aspect of the present invention, a rubber compounding apparatus is provided, comprising a roll assembly, a pad conveying assembly, and the aforementioned rubber compound conveying device. The pad conveying assembly has a support roller for conveying the pad, the support roller serving as a second conveying roller. A traverse conveying assembly of the rubber compound conveying device conveys the rubber compound to the infeed roller of the rubber compound conveying device, the pad conveying assembly conveys the pad to the infeed roller of the rubber compound conveying device, the infeed roller compounding the rubber compound and the pad and conveying them to the roll assembly, and the roll assembly winding up the rubber compound.

[0014] By applying the technical solution of this invention, the movable roller and the transverse conveying assembly allow the rubber material to have two conveying paths when it is conveyed to the roll assembly. This not only ensures that the material tail is not kinked during conveying but also ensures that the material head is smoothly fed into the roll, thereby saving rubber material, reducing waste, and lowering production costs. Specifically, in this embodiment, the movable roller is movably configured. During normal rubber material conveying, the movable roller is in a clearance position, allowing the rubber material to be directly conveyed from the transverse conveying assembly to the in-roll roller, thus ensuring conveying efficiency. When the material tail is conveyed, the movable roller moves to the working position, allowing the material tail to be conveyed from the transverse conveying assembly. The material is fed to the movable roller, and then from the bottom surface of the movable roller, it continues to be conveyed to the top surface of the in-wound roller. In this way, the movable roller pushes the tail of the rubber material away from the in-wound roller, so that the rubber material downstream of the in-wound roller is smoothly wound up, and the rubber material upstream of the in-wound roller is pushed to the movable roller away from the in-wound roller. This prevents the tail of the material from falling heavily to the winding assembly due to gravity and other factors after leaving the transverse conveyor assembly, causing stacking and wrinkles. On the other hand, when the head of the rubber material is conveyed to the transverse conveyor assembly, the transverse conveyor assembly can adjust the conveying direction of the rubber material so that the rubber material can be conveyed laterally to the in-wound roller, achieving smooth feeding and avoiding folding of the head of the material, thereby avoiding the generation of waste.

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] 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.

[0019] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0020] To address the problem in existing technologies where the rubber compound tail tends to fold and generate waste when the winding process is nearing completion, this invention provides a rubber compound conveying device and a rubber compound compounding device.

[0021] like Figures 1 to 3 The illustrated rubber material conveying device includes a transverse conveying assembly 10 for transversely conveying rubber material, an infeed roller 20, and a movable roller 30. Along the conveying direction of the rubber material, the infeed roller 20 is located downstream of the transverse conveying assembly 10. The movable roller 30 is movably disposed relative to the transverse conveying assembly 10. The movable roller 30 has a clearance position to avoid the conveying path of the rubber material and a working position to move into the conveying path of the rubber material. When the movable roller 30 is in the clearance position, the rubber material passes through the transverse conveying assembly 10 and the infeed roller 20 in sequence and enters the roll assembly 70 to form a roll. When the movable roller 30 is in the working position, the movable roller 30 is located between the transverse conveying assembly 10 and the infeed roller 20 and pushes the rubber material downward. The rubber material passes through the bottom surface of the movable roller 30 and the top surface of the infeed roller 20 in sequence and then enters the roll assembly 70.

[0022] This embodiment, by setting up a movable roller 30 and a transverse conveying assembly 10, allows the rubber material to have two conveying paths when conveyed to the roll assembly 70. This not only ensures that the material tail is not kinked when conveying, but also ensures that the material head is smoothly enclosed when conveying, thereby saving rubber material, reducing waste, and lowering production costs. Specifically, in this embodiment, the movable roller 30 is movably set. During normal rubber material conveying, the movable roller 30 is in a clearance position, allowing the rubber material to be directly conveyed from the transverse conveying assembly 10 to the enclosed roller 20, thus ensuring conveying efficiency. When conveying the material tail, the movable roller 30 moves to the working position, allowing the material tail to be conveyed from the transverse conveying assembly 10 to the movable roller 30, and then from the movable roller 30... The bottom surface output of 0 continues to be conveyed to the top surface of the in-wound roller 20. In this way, with the push of the movable roller 30, the tail of the rubber material moves away from the in-wound roller 20, so that the rubber material downstream of the in-wound roller 20 is smoothly wound up, and the rubber material upstream of the in-wound roller 20 is pushed to the side of the movable roller 30 away from the in-wound roller 20. This avoids the tail of the material from falling heavily to the winding assembly 70 due to gravity and other factors after leaving the transverse conveyor assembly 10, causing stacking and wrinkling, and thus avoiding the generation of waste. On the other hand, when the head of the rubber material is conveyed to the transverse conveyor assembly 10, the transverse conveyor assembly 10 can adjust the conveying direction of the rubber material so that the rubber material can be conveyed laterally to the in-wound roller 20, achieving smooth feeding and avoiding the head of the material from being folded, thereby avoiding the generation of waste.

[0023] It should be noted that, in this embodiment, the downward pushing of the rubber material by the movable roller 30 refers to the downward movement of the movable roller 30 when it switches from the avoidance position to the working position. During the switching process, the movable roller 30 abuts against the rubber material and drives it downward, thereby changing the conveying path of the rubber material. Here, "downward" does not only refer to vertical downward, but can also refer to inclined downward. Specifically, during the switching process, the movable roller 30 can abut against the rubber material being conveyed from the transverse conveyor assembly 10 to the in-wound roller 20 and drive the rubber material to continue moving to the working position. This causes the conveying path from the transverse conveyor assembly 10 to the in-wound roller 20 to bend, so that the rubber material directly conveyed between the transverse conveyor assembly 10 and the in-wound roller 20 becomes conveyed in a zigzag pattern between the transverse conveyor assembly 10, the movable roller 30, and the in-wound roller 20. This avoids the large drop and stacking of the material tail due to the height difference between the transverse conveyor assembly 10 and the in-wound roller 20, which would cause folding.

[0024] In this embodiment, when the movable roller 30 is in the working position, the transverse conveying assembly 10, the movable roller 30, and the infeed roller 20 are arranged sequentially along the height direction, so that the height of the material tail decreases sequentially during the conveying process, thereby further reducing the probability of the material tail folding.

[0025] In this embodiment, the rubber material conveying device also includes a second conveying roller 40. When the movable roller 30 is in the working position, the second conveying roller 40 is farther away from the in-wound roller 20 than the movable roller 30. When the tail of the rubber material is conveyed to the movable roller 30, the tail falls to the second conveying roller 40, so that the tail can be spread flat on the second conveying roller 40 under the push of the movable roller 30, so that the tail can be smoothly conveyed to the in-wound roller 20 later. Specifically, along the height direction, the second conveyor roller 40 is located between the transverse conveyor assembly 10 and the infeed roller 20. When the movable roller 30 is in the working position, the second conveyor roller 40 is located between the transverse conveyor assembly 10 and the infeed roller 20. Along the horizontal direction, when the movable roller 30 is in the working position, the movable roller 30 is located between the infeed roller 20 and the second conveyor roller 40. In this way, when the material tail falls off the transverse conveyor assembly 10 due to its short length, since the second conveyor roller 40 is closer to the movable roller 30 than the transverse conveyor assembly 10, and the height of the second conveyor roller 40 is between the movable roller 30 and the transverse conveyor assembly 10, the material tail can fall onto the second conveyor roller 40 under the push of the movable roller 30. This allows the second conveyor roller 40 to continue supporting the material tail in place of the transverse conveyor assembly 10, so that the material tail can continue to be conveyed to the movable roller 30 and the infeed roller and then wound up by the winding assembly.

[0026] In this embodiment, the movable roller 30 is located below the transverse conveying assembly 10, allowing the rubber material to be directly conveyed to the movable roller 30 via the transverse conveying assembly 10 without the need for an additional power conveying device. Preferably, the movable roller 30 is located directly below the transverse conveying assembly 10, which helps to save space occupied by the rubber material conveying device and improve space utilization.

[0027] Preferably, the infeed roller 20, the second conveyor roller 40, and the roll assembly 70 are also located directly below the transverse conveyor assembly 10, so that the entire roll of the rubber material can be completed directly below the transverse conveyor assembly 10, which can provide a relatively stable working environment for the roll of the rubber material and save space.

[0028] In this embodiment, the movable roller 30 is rotatably configured relative to the transverse conveying assembly 10, allowing it to flexibly switch between a clearance position and a working position, thereby improving the flexibility of the rubber material conveying device. Specifically, when the movable roller 30 is in the clearance position, it can be retracted into the bottom of the transverse conveying assembly 10, thus making full use of the space below the transverse conveying assembly 10. When the movable roller 30 switches to the working position, it can swing downwards away from the transverse conveying assembly 10 and into the conveying path of the rubber material, thereby adjusting the conveying direction of the rubber material and achieving anti-bumping treatment of the material tail. Of course, the configuration of the movable roller 30 is not unique; it is sufficient to achieve switching between the clearance position and the working position. For example, the movable roller 30 can also be configured to be retractable relative to the transverse conveying assembly 10. When the movable roller 30 is in the clearance position, it retracts into the bottom of the transverse conveying assembly 10, and the clearance position is switched to the working position through the extension of the relevant telescopic component.

[0029] In this embodiment, the rubber material conveying device further includes a swing arm 50 and a swing drive 60. The swing arm 50 is connected to the movable roller 30 and is rotatably mounted on the transverse conveying assembly 10. The swing drive 60 is drivenly connected to the swing arm 50 and drives the swing arm 50 to switch the movable roller 30 between a clearance position and a working position. In this way, the movable roller 30 can flexibly switch between the clearance position and the working position, thereby achieving position switching at the appropriate time, preventing the rubber material from folding, and improving the rubber material winding efficiency. Specifically, the swing drive 60 can be fixed to the frame 13 of the rubber material conveying device. In this embodiment, to avoid interference, the swing drive 60 is fixed to the edge of the frame 13 of the rubber material conveying device. The swing arm 50 can be configured as a rod. One end of the swing arm 50 is connected to the movable roller 30, and the other end of the swing arm 50 is connected to the transverse conveying assembly 10. The connection point between the swing arm 50 and the transverse conveying assembly 10 is the first connection point. A second connection point is provided between the two ends of the swing arm 50. The swing arm 50 is connected to the swing drive 60 through the second connection point. In this way, the swing drive 60 drives the swing arm 50 to rotate around the first connection point and drives the movable roller 30 to swing around the first connection point as the center, so as to realize the switching of the movable roller 30 between the avoidance position and the working position. Optionally, the swing drive 60 can be a cylinder, electric cylinder, etc. In this embodiment, the swing drive 60 is a cylinder. When the rubber material is nearly fully rolled, the cylinder rod of the swing drive 60 extends, and the movable roller 30 presses the rubber sheet to roll it up until it is completely rolled. After the rolling is completed, the cylinder rod of the swing drive 60 retracts, and the swing arm 50 is arranged vertically parallel to the transverse conveying assembly 10.

[0030] In this embodiment, the first connection point along the horizontal direction is located between the in-wound roller 20 and the second conveying roller 40. This allows the movable roller 30 to be in the avoidance position, with the swing arm 50 and the movable roller 30 horizontally housed at the bottom of the transverse conveying assembly 10. The movable roller 30 is located on the side of the in-wound roller 20 away from the second conveying roller 40, thus avoiding the conveying path of the rubber material and preventing interference with the rubber material or other components. When the movable roller 30 is in the working position, the swing arm 50 can extend vertically downwards or tilted downwards. Specifically, the swing arm 50... Driven by the swaying drive 60, the movable roller 30 is swayed towards the second conveying roller 40 and downward. After reaching the conveying path of the rubber material and coming into contact with it, the roller continues to move the rubber material, thereby changing the conveying path of the rubber material. This allows the rubber material to wrap around the side of the movable roller 30 away from the in-wound roller 20 and the bottom surface of the movable roller 30, and increases the wrap angle of the rubber material on the in-wound roller 20. As a result, the movable roller 30 can generate a certain pushing force and restraining force on the rubber material, preventing the material tail from falling freely and causing folding.

[0031] In this embodiment, the transverse conveying assembly 10 includes a plurality of first conveying rollers 11, which are spaced apart and arranged laterally. Along the arrangement direction of the first conveying rollers 11, each first conveying roller 11 sequentially conveys the rubber material. Thus, when the rubber material reaches the transverse conveying assembly 10, the continuous conveying by the plurality of first conveying rollers 11 adjusts the conveying direction of the rubber material to a horizontal direction, thereby mitigating the downward trend caused by the weight of the rubber material and allowing it to be smoothly conveyed to the in-wound roller 20, thereby achieving smooth in-wound feeding. In this embodiment, before reaching the transverse conveying assembly 10, the rubber material is conveyed from top to bottom. After the head of the rubber material falls onto the transverse conveying assembly 10, it passes sequentially through each first conveying roller 11, thereby adjusting the conveying direction of the rubber material to horizontal and mitigating the downward trend caused by gravity, making the conveying speed of the rubber material more stable, thus achieving smooth in-wound feeding.

[0032] In this embodiment, at least one first conveying roller 11 includes a plurality of rollers 111, the arrangement direction of each roller 111 being perpendicular to the arrangement direction of each first conveying roller 11, and the axial direction of each roller 111 being perpendicular to the arrangement direction of each first conveying roller 11, thereby reducing the frictional force experienced by the rubber material during conveying and improving the production quality of the rubber material. Specifically, the rollers 111 in this embodiment can be spherical or annular, so that the rubber material can absorb small displacements from multiple directions caused by factors such as bumps and vibrations, avoiding phenomena such as rubber material stretching and wrinkling caused by other factors. Figure 2As shown, the roller 111 in this embodiment adopts a circular bidirectional bearing, so that when the local rubber material generates a forward or backward pulling force, the roller 111 can rotate with the position of the rubber material, thereby reducing the friction and deformation of the rubber material and ensuring the production quality of the rubber material.

[0033] In this embodiment, multiple rows of rollers 111 are arranged along the conveying direction of the rubber compound, which facilitates the smooth feeding of the rubber compound into the roll. The rollers 111 can be either unpowered or powered. Preferably, the rollers 111 are unpowered, so that when the rubber compound passes over the upper surface of the rollers 111, each roller 111 can roll both in the conveying direction of the rubber compound and against the conveying direction of the rubber compound, thereby avoiding folding caused by differences in the width direction of the rubber compound during conveying.

[0034] In this embodiment, the transverse conveying assembly 10 further includes a transverse drive 12, which is drivenly connected to each of the first conveying rollers 11. When conveying the rubber material, the transverse drive 12 drives each of the first conveying rollers 11 to move laterally into the falling path of the rubber material. The transverse direction of the first conveying rollers 11 is consistent with the arrangement direction of each of the first conveying rollers 11, thereby adjusting the conveying direction of the rubber material so that the rubber material can be smoothly wound after a period of horizontal conveying. Specifically, along the conveying direction of the rubber material, the transverse conveying assembly 10 has a first end and a second end that are arranged opposite to each other. When the rubber material falls onto the transverse conveying assembly 10, it is conveyed towards the direction closer to the second end. In this embodiment, the transverse drive 12 is located at the first end of the transverse conveying assembly 10. When no rubber material passes through, the transverse drive 12 and each of the first conveying rollers 11 are both located at the first end of the transverse conveying assembly 10 to avoid other components and other processing steps of the rubber material. When the rubber material falls from top to bottom to the winding assembly below the transverse conveying assembly 10, the transverse drive 12 pushes each of the first conveying rollers 11 to move away from the first end and comes into contact with the vertically falling rubber material, driving the rubber material to move away from the first end. This allows the rubber material to move with each of the first conveying rollers 11 to the second end of the transverse conveying assembly 10, ensuring that the rubber material is conveyed horizontally over a certain distance. This makes the movement of the rubber material more stable and ensures that the rubber material maintains a certain tension during the winding process, preventing the rubber material from folding. Optionally, the transverse drive 12 can be a cylinder, electric cylinder, etc. In this embodiment, the transverse drive 12 is a cylinder. When the material head hangs down and does not enter the winding, the cylinder can adjust the throttle valve at the cylinder inlet end to match the production line speed. The cylinder rod extends, and at this time the material head will be wound into the winding assembly 70 along with the padding cloth, and winding begins. After winding is completed, the cylinder rod of the transverse drive 12 retracts and returns to the initial position, waiting for the next winding cycle. It should be noted that the production line mentioned in this embodiment refers to the production line for rubber materials, specifically a production line that transports rubber materials from top to bottom.

[0035] In this embodiment, the plurality of first conveying rollers 11 also include a contact roller 112. Compared to the other first conveying rollers 11, the roller 112 is located at the end of the transverse conveying assembly 10 and is closer to the in-wound roller 20 along the conveying direction of the rubber material. When the transverse drive 12 drives each first conveying roller 11 to move laterally away from the first end, the contact roller 112 first comes into contact with the rubber material and drives the rubber material to move away from the first end. Then, as each first conveying roller 11 continues to move towards the second end, the rubber material is spread evenly on the upper surface of each first conveying roller 11.

[0036] In this embodiment, after each first conveying roller 11 moves laterally to the position of conveying the rubber material, the contact roller 112 and the feed roller 20 are located on the same side of the winding assembly 70 in the horizontal direction, and the contact roller 112 is farther away from the winding assembly 70 than the feed roller 20. As a result, when the material head falls to the winding assembly 70, the rubber material moves with the first conveying roller 11 to the end of the lateral conveying assembly 10 through the lateral movement of each first conveying roller 11. At the same time, the rubber material can come into contact with the contact roller 112 and form a certain wrap angle on the contact roller 112 and the feed roller, thereby forming a certain tension in the rubber material and allowing the material head to be smoothly wound.

[0037] like Figure 2 , Figure 3 As shown, in this embodiment, the transverse conveying assembly 10 further includes a frame 13 and a slider 14. The frame 13 has a guide rail extending along the arrangement direction of each first conveying roller 11. The slider 14 is connected to each first conveying roller 11 and is slidably disposed within the guide rail. The slider 14 can drive each first conveying roller 11 to move along the extension direction of the guide rail, thereby making the transverse direction of each first conveying roller 11 more accurate and reliable. Specifically, guide rails are provided at both sides of the frame 13 along the arrangement direction of each first conveying roller 11, and a slider 14 is provided in each guide rail. Both ends of each first conveying roller 11 are connected to the slider 14, and a transverse drive member 12 is provided on each side of the frame 13. The transverse drive member 12 is driven to each first conveying roller 11 through the slider 14. Thus, when the transverse drive member 12 drives the slider 14 to move along the guide rail, each first conveying roller 11 moves synchronously along the extension direction of the guide rail to achieve material receiving or avoidance.

[0038] In this embodiment, the transverse conveying assembly 10 further includes a rotatably mounted guide roller 15, and there is a gap between the guide roller 15 and the first conveying roller 11 for the rubber material to pass through. The rubber material passes through each of the first conveying rollers 11 in sequence and then leaves the transverse conveying assembly 10 through the gap, thereby providing support and guidance for the conveying of the rubber material. Specifically, the guide roller 15 is located at the end of each of the first conveying rollers 11 away from the transverse drive member, that is, at the second end of the transverse conveying assembly 10, and can rotate about its own axis. In this embodiment, along the conveying direction of the rubber material, the guide roller 15 is located downstream of the contact roller 112, and the guide roller 15 and each of the first conveying rollers 11 are arranged transversely, thereby forming a gap that extends through the height direction between the contact roller 112 and the guide roller 15, so that the rubber material can pass through the gap from top to bottom and move onto the infeed roller 20 or the movable roller 30 below the transverse conveying assembly 10. The guide roller 15 is configured as a round rod, and its two ends are rotatably connected to the frame 13. This allows the guide roller 15 to rotate with the movement of the rubber material as it passes through the gap, thereby reducing the friction during the conveying process and providing guidance and support, so that the rubber material can smoothly leave the transverse conveying assembly 10.

[0039] In this embodiment, the rubber material conveying device further includes a detection element located at the sway drive 60. The detection element detects the operating state of the sway drive 60, thereby enabling real-time judgment of the movement of the sway drive 60 and achieving real-time control of the position of the movable roller 30. The detection element can also be located at the transverse drive 12 and detect its operating state, thereby enabling real-time judgment of the movement of the transverse drive 12 and achieving real-time control of the position of each first conveying roller 11. Optionally, the detection element can be a magnetic switch used to detect the extension and retraction of the cylinder rod.

[0040] To facilitate the installation of the rubber material conveying device, a connecting rod is provided on the top of the rubber material conveying device in this embodiment. The rubber material conveying device can be installed on the hanger through the connecting rod, so that the rubber material conveying device can be suspended below the hanger.

[0041] like Figure 1As shown, this embodiment also provides a rubber compounding device, including a roll assembly 70, a padding fabric conveying assembly 80, and the aforementioned rubber compound conveying device. The padding fabric conveying assembly 80 has a support roller for conveying the padding fabric, which serves as a second conveying roller 40. The lateral conveying assembly 10 of the rubber compound conveying device conveys the rubber compound to the infeed roller 20 of the rubber compound conveying device, and the padding fabric conveying assembly 80 conveys the padding fabric to the infeed roller 20 of the rubber compound conveying device. The infeed roller 20 combines the rubber compound and the padding fabric and conveys them to the roll assembly 70. The roll assembly 70 winds up the rubber compound, thereby realizing the compounding of the rubber compound and the padding fabric. Specifically, considering the compact structure of the rubber compounding device, the roll assembly 70 of this embodiment is located directly below the rubber compound conveying device and is used to wind the compounded rubber compound and the padding fabric into a roll. The padding fabric conveying device is positioned opposite the roll assembly 70, near the infeed roller 20. This allows both the padding fabric and the adhesive to be conveyed to the infeed roller 20 via an optimized path, where they are compounded. The last roller the padding fabric passes before reaching the infeed roller 20 is a support roller, which is slightly higher than the infeed roller 20 in height to facilitate the infeeding of the padding fabric. When the tail of the adhesive is conveyed to the movable roller 30, the support roller simultaneously acts as a second conveying roller 40. Under the push of the movable roller 30, the tail of the adhesive is laid flat on the support roller, allowing it to be smoothly wound up without folding, thus preventing waste.

[0042] The rubber material conveying device in this embodiment adopts a structural layout suitable for reverse winding components. After the rubber material is fed into the roll, it is pushed forward by the lateral drive 12, which is similar to a forward winding method. When conveying the tail of the rubber material, the rubber material swings backward under the action of the movable roller 30 and spreads flat on the first conveying roller 11. The rubber material is conveyed by rolling transmission. Because the diameter of the roll is very large when it is fully wound, the rubber material cannot be completely wrapped with the padding cloth. Therefore, the movable roller 30 presses the tail of the rubber material to wind it until the roll is fully wound. The whole process can effectively solve the problem of folding at the tail of the material, eliminate the generation of waste material, improve the efficiency of the entire winding production line, reduce costs, and increase profits.

[0043] The working process of the rubber material conveying device in this embodiment is as follows: 1. Winding start: After the material head hangs down, when the material head is about to be wound into the roll that has not yet been wound into the winding assembly 70, the time is calculated according to the distance and speed. The speed determines the time when the transverse drive 12 starts to move. At this time, the cylinder rod of the transverse drive 12 starts to extend, driving each first conveying roller 11 to move laterally away from the first end. The transverse speed matches the speed of the production line conveying the rubber material. The material head is wound into the roll, and winding begins. 2. Winding process: According to the actual measured length of the meter wheel or according to the proportion of the roll of the winding assembly 70 to be fully wound, the cylinder rod of the swing arm drive is extended. The cylinder rod of the swing arm drive drives the movable roller 30 to swing to the working position. The movable roller 30 rolls the rubber material. The rubber material slides down from the conveyor belt from top to bottom and is spread flat on each first conveying roller 11. At this time, the rubber material rolls on each first conveying roller 11 until the rubber material is completely wound into the pad, that is, the roll is fully wound. 3. End of winding: The cylinder rod of the swing arm drive retracts and drives the movable roller 30 to swing to the avoidance position. The cylinder rod of the transverse drive 12 retracts and drives each first conveying roller 11 to move laterally towards the first end of the transverse conveying assembly 10, that is, return to the initial state and prepare for the next winding.

[0044] It should be noted that "multiple" in the above embodiments refers to at least two.

[0045] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: 1. This solves the problem in existing technologies where the rubber compound tail tends to fold and generate waste material when the winding process is almost complete; 2. By setting up movable rollers and transverse conveying components, the rubber material can be conveyed to the roll assembly through two paths. This not only ensures that the material tail does not fold when conveying, but also ensures that the material head can be smoothly rolled, thereby saving rubber material, reducing waste, and lowering production costs. 3. In this embodiment, the movable roller is movably configured. When the rubber material is being conveyed normally, the movable roller is in the clearance position, allowing the rubber material to be directly conveyed from the transverse conveyor assembly to the in-wound roller, thereby ensuring conveying efficiency. When the rubber material reaches the tail end, the movable roller moves to the working position, allowing the tail end to be conveyed from the transverse conveyor assembly to the movable roller, and then output from the bottom surface of the movable roller to continue conveying to the top surface of the in-wound roller. In this way, with the push of the movable roller, the tail end of the rubber material moves away from the in-wound roller, so that the rubber material downstream of the in-wound roller is smoothly wound up, and the rubber material upstream of the in-wound roller is pushed to the side of the movable roller away from the in-wound roller, avoiding the tail end from falling significantly to the winding assembly due to gravity and other factors after leaving the transverse conveyor assembly, causing stacking wrinkles. 4. When the rubber material head is conveyed to the transverse conveyor assembly, the transverse conveyor assembly can adjust the conveying direction of the rubber material so that the rubber material can be conveyed laterally to the infeed roller, achieving smooth feeding, avoiding kinking of the material head, and thus avoiding the generation of waste.
