Description

Technical Field

[0001] This utility model relates to the field of tire processing, and more specifically, to a fabric feeding rack. Background Technology

[0002] In tire manufacturing, the bonding between the rubber compound and the steel rim during bead production typically relies on adhesives. However, a more refined process exists: the U-shaped fabric wrapping process. This involves using a layer of nylon fabric to bond the steel rim and rubber compound, covering and sealing the seam between them. In this process, the fabric is first applied to the drum, then the bead is placed on the fabric, and finally, the fabric and bead are bonded together. During the fabric feeding and bonding process, because a fixed length of U-shaped fabric needs to be fed to the drum for bonding, risks such as material roll-up and swaying can occur, leading to unstable overlap and length of the fabric at the beginning and end of the wrap. Unstable overlap directly affects the coverage of the bead by the U-shaped fabric, thus impacting the bead's stability. Utility Model Content

[0003] The main purpose of this utility model is to provide a fabric feeding rack to solve the problem of unstable overlap between the front and back ends of the fabric in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a fabric feeding rack is provided, comprising: a frame, a fabric conveying device, and a bonding device, wherein the bonding device is movably disposed at the end of the fabric conveying device and located at the capsule drum device, and the bonding device rotates to bond the fabric to the capsule drum device; the bonding device includes a cutting component.

[0005] Furthermore, the bonding device also includes: a feeding assembly, a suction assembly, and a pressure roller assembly. Along the fabric conveying direction, the cutting assembly is located downstream of the feeding assembly, and the feeding assembly is used to convey the cut fabric head towards the capsule drum device. Along the fabric conveying direction, the suction assembly is located downstream of the feeding assembly, and the cutting assembly is located between the suction assembly and the feeding assembly. The suction assembly is used to suck up and convey the fabric head on the feeding assembly to the capsule drum device. Along the fabric conveying direction, the suction assembly is located upstream of the pressure roller assembly, and the pressure roller assembly is used to roll the fabric on the capsule drum device.

[0006] Furthermore, the fabric feeding rack also includes a pressing device, which is located at the axial end face of the capsule drum device. The pressing device includes a rotatable pressing arm that can swing to the circumferential side of the capsule drum device and press the fabric.

[0007] Furthermore, the pressing device also includes a pressing drive and a pressing drive, both of which are driven to the pressing arm. The pressing drive can drive the pressing arm to swing to the circumferential side of the capsule drum device, and the pressing drive can drive the pressing arm to press the wrapping fabric.

[0008] Furthermore, the cutting assembly includes a cutter for cutting the covering fabric and multiple pressure blocks, each pressure block being arranged along the conveying direction of the covering fabric, and pressure blocks being provided on both sides of the cutter. When the cutter cuts the covering fabric, the pressure blocks press the covering fabric tightly.

[0009] Furthermore, the cutting assembly also includes a cutter drive and a pressure block drive. The cutter drive is connected to the cutter drive and cuts the cover fabric before it is fully attached to the capsule drum. The pressure block drive is connected to the pressure block drive and drives the pressure block to press the cover fabric tightly when the cutter cuts it.

[0010] Furthermore, the feeding assembly includes a feeding tray and a feeding drive. The feeding tray is movably connected to the fabric conveying device; the feeding drive is driven to the feeding tray and drives the feeding tray to move along the fabric conveying direction.

[0011] Furthermore, the fabric feeding rack also includes a length-fixing device, which is located above the fabric conveying device and measures the length of the fabric.

[0012] Furthermore, the fabric feeding rack also includes an adjustment component, which is disposed between the fabric conveying device and the bonding device. The bonding device moves laterally relative to the fabric conveying device via the adjustment component.

[0013] Furthermore, the fabric conveying device is rotatably connected to the frame, and the fabric feeding frame also includes a lifting component. The lifting component is driven to connect to the conveying device and drives the fabric conveying device and the bonding device to lift and swing synchronously.

[0014] By applying the technical solution of this utility model, the cutting component is placed on the bonding device close to the capsule drum device, thereby shortening the distance between the cutting component and the capsule drum device. This allows the cutting component to cut the fabric being bonded, improving the transmission stability of the fabric feeding frame, improving the overlap effect of the fabric head and tail, and reducing the risks of material rolling and shaking. Specifically, the fabric head can be bonded to the capsule drum device first, before the fabric is cut, ensuring the stability of the bonding position and preventing the fabric tail from falling off after cutting. When the fabric has bonded a predetermined distance but is not completely bonded to the capsule drum device, the cutting component cuts the fabric being bonded, forming the fabric tail of the fabric being bonded and the head of the next section of fabric. Because the distance between the cutting point and the capsule drum device is short at this time, the cutting component can smoothly cut the fabric being bonded, and the cut fabric tail... It can stably adhere to the capsule drum device, thereby reducing vibration during the fabric cutting process to ensure a flat interface and accurate positioning of the fabric on the capsule drum device. It also avoids issues such as fabric tail curling and wrinkling. This stability of the fabric bonding process and the bonding stability of the fabric head and tail both contribute to improving the overlap effect of the fabric head and tail, avoiding problems such as overlap failure. Moreover, the fabric feeding rack in this embodiment has a simple structure and is easy to operate. It does not require additional positioning and conveying mechanisms. Compared with the traditional fabric feeding device that first cuts the fabric to a fixed length and then attaches it to the capsule drum device, the fabric feeding rack in this embodiment can directly feed the fabric to the fabric feeding rack by the fabric guiding mechanism. This saves the intermediate process of conveying and positioning the cut fixed-length fabric, thereby reducing the probability of fabric deviation and improving the accuracy of the fabric's bonding position on the capsule drum device. It also simplifies the structure of the fabric feeding rack. Attached Figure Description

[0020] 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.

[0021] 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.

[0022] In this utility model, 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 used to limit this utility model.

[0023] To address the problem of unstable overlap between the beginning and end of the fabric in existing technologies, this invention provides a fabric feeding rack.

[0024] In this embodiment, the tire bead refers to the steel rim and the rubber compound, with a seam at the joint between them. After the wrapping fabric 20 is wrapped around the bladder drum device 10 once, the tire bead is placed on the outer periphery of the wrapping fabric 20. Then, the wrapping fabric 20 is applied to the tire bead in a U-shape, thus covering both sides of the tire bead and simultaneously wrapping the seam between the steel rim and the rubber compound, thereby improving the stability of the tire bead. The wrapping fabric feeding rack in this embodiment is mainly used to transport and apply the wrapping fabric 20 to the bladder drum device 10. This is a process before the wrapping fabric 20 wraps the tire bead. The smooth and accurate application of the wrapping fabric 20 to the bladder drum device 10 is crucial for the subsequent reliable wrapping of the tire bead by the wrapping fabric 20.

[0025] like Figures 1 to 2 The fabric feeding frame shown includes a frame 311, a fabric conveying device 312, and a bonding device 313. The bonding device 313 is movably disposed at the end of the fabric conveying device 312 near the capsule drum device 10 and located at the capsule drum device 10. The bonding device 313 rotates and bonds the fabric 20 to the capsule drum device 10. The bonding device 313 includes a cutting component 3134.

[0026] In this embodiment, by placing the cutting component 3134 on the bonding device 313 near the capsule drum device 10, the distance between the cutting component 3134 and the capsule drum device 10 is shortened. This allows the cutting component 3134 to cut the fabric 20 being bonded, thereby improving the transmission stability of the fabric feeding frame, improving the overlap effect of the fabric head and tail, and reducing the risks of material rolling and shaking. Specifically, the fabric head of the fabric 20 can be bonded to the capsule drum device 10 first, at which point the fabric 20 is not cut. The cutting component 3134 ensures the stability of the bonding position of the fabric 20 and avoids malfunctions such as the tail of the fabric 20 falling off after cutting. When the fabric is bonded to a predetermined distance but not completely bonded to the capsule drum device 10, the cutting component 3134 cuts the fabric 20 that is being bonded, thus forming the tail of the fabric 20 being bonded and the head of the next section of fabric 20. Since the distance between the cutting point and the capsule drum device 10 is short at this time, the cutting component 3134 can smoothly cut the fabric 20 being bonded. The cut end of the fabric 20 can be smoothly attached to the capsule drum device 10, thereby reducing vibration during the cutting process and ensuring a smooth interface. It also ensures the accuracy of the fabric 20's attachment position on the capsule drum device 10, preventing the end of the fabric 20 from curling or wrinkling. This improved stability of the fabric 20's attachment process and the adhesion of the beginning and end of the fabric improves the overlap effect, avoiding overlap failures. Furthermore, the fabric feeding rack in this embodiment has a simple structure. It is easy to operate and does not require additional positioning and conveying mechanisms. Compared with the traditional cloth feeding device that first cuts the cloth 20 to a fixed length and then attaches it to the capsule drum device 10, the cloth feeding frame of this embodiment can directly convey the cloth 20 to the cloth feeding frame by the cloth guiding mechanism, saving the intermediate conveying and positioning process of the cut cloth to a fixed length, thereby reducing the probability of cloth 20 deviation, thereby improving the accuracy of the attachment position of cloth 20 on capsule drum device 10, and simplifying the structure of cloth feeding frame.

[0027] In this embodiment, the bonding device 313 is located at one end of the fabric feeding rack near the capsule drum device 10, and can bond the fabric 20 to the capsule drum device 10. Both the fabric feeding device 312 and the bonding device 313 are positioned above the frame 311, with the bonding device 313 closer to the capsule drum device 10 than the fabric feeding device 312. The frame 311 has a certain height, ensuring that the end of the bonding device 313 near the capsule drum device 10 is at a certain height, allowing the end of the capsule drum device 10 to be positioned above it, facilitating the bonding of the fabric 20. The cutting component 3134, as part of the bonding device 313, is also located near the capsule drum device 10. When the fabric 20 is bonded to the capsule drum device 10, it can cut off the tail of the fabric 20 being bonded, forming the head of the next section of fabric 20. In this way, compared to the traditional process of cutting the wrapping fabric 20 before bonding, the cutting component 3134 in this embodiment is set on the bonding device 313, which makes the cutting component 3134 closer to the capsule drum device 10. This shortens the distance between the cutting component 3134 and the capsule drum device 10, so that the wrapping fabric 20 does not need to be cut before bonding. When the cutting component 3134 is activated, the wrapping fabric 20 has already been partially bonded and fixed to the capsule drum device 10, thereby shortening the distance from the fixed point of the wrapping fabric 20 to the cutting point. This reduces the shaking and displacement of the wrapping fabric 20 during the cutting process, thereby ensuring the accuracy of the cutting position and improving the accuracy of the bonding of the wrapping fabric 20.

[0028] In this embodiment, the bonding device 313 further includes a feeding assembly 3131, a suction assembly 3132, and a pressure roller assembly 3133. Along the conveying direction of the fabric 20, the cutting assembly 3134 is located downstream of the feeding assembly 3131, and the feeding assembly 3131 is used to convey the cut end of the fabric 20 towards the capsule drum device 10. Along the conveying direction of the fabric 20, the suction assembly 3132 is located downstream of the feeding assembly 3131, and the cutting assembly 3134 is located between the suction assembly 3132 and the feeding assembly 3131. The suction assembly 3132 is used to suck up and convey the end of the material on the feeding assembly 3131 to the capsule drum device 10. Along the conveying direction of the fabric 20, the suction assembly 3132 is located upstream of the pressure roller assembly 3133, and the pressure roller assembly 3133 is used to roll the fabric 20 on the capsule drum device 10. In this way, through the coordinated action of the feeding component 3131, the suction component 3132 and the pressure roller component 3133, the fabric 20 is precisely fitted and firmly fixed. The feeding component 3131 can ensure the accurate positioning of the fabric 20 head, the suction component 3132 will absorb the head and send it to the capsule drum device 10, and the pressure roller component 3133 will make the fabric 20 fit tightly against the surface of the capsule drum device 10 through the rolling action.

[0029] like Figure 1 , Figure 2As shown, in this embodiment, the bonding device 313 is movably arranged relative to the fabric conveying device 312 along the conveying direction of the fabric 20, and the feeding assembly 3131, the cutting assembly 3134, the suction assembly 3132, and the pressure roller assembly 3133 are arranged sequentially along the conveying direction of the fabric 20. Specifically, the feeding assembly 3131 is movably arranged relative to the fabric conveying device 312. When the head of the fabric 20 is conveyed to the feeding assembly 3131, the feeding assembly 3131 can move relative to the fabric conveying device 312 towards the capsule drum device 10, thereby conveying the head of the fabric 20 directly below the suction assembly 3132. The suction assembly 3132 is vertically adjustable. When the feeding assembly 3131 conveys the head of the fabric 20 directly below the suction assembly 3132, the suction assembly 3132 can fall and absorb the head of the fabric 20. Simultaneously, the suction component 3132 can be moved along the conveying direction of the fabric 20, thereby enabling the suction component 3132 to adsorb the material head and convey it to the capsule drum device 10. When the fabric 20 is partially attached to the capsule drum device 10 but not completely attached, that is, when the fabric 20 is close to its fixed length, the cutting component 3134 cuts the fabric 20, so that the fabric 20 being attached is separated from the subsequent fabric 20 being conveyed, thereby allowing the material tail of the fabric 20 being attached to be smoothly attached to the capsule drum device 10. When the material head of the fabric 20 is attached to the capsule drum device 10, the capsule drum device 10 rotates, so that the fabric 20 can be attached to the outer periphery of the capsule drum device 10 along the rotation direction of the capsule drum device 10. The pressure roller assembly 3133 is located at the end of the bonding device 313 away from the fabric conveying device 312. When the material head is bonded to the capsule drum device 10, after the capsule drum device 10 rotates at a small angle, the material head moves away from the bonding device 313 as the capsule drum device 10 rotates. At this time, the pressure roller assembly 3133 falls down and presses the fabric 20, so that the fabric 20 is stably wrapped around the capsule drum device 10.

[0030] The feeding assembly 3131 in this embodiment includes a feeding tray and a feeding drive. The feeding drive and the feeding tray are driven together. The feeding drive can be disposed below the feeding tray and connected to the fabric conveying device 312. The feeding tray is movably connected to the fabric conveying device 312. The fabric 20 is conveyed to the feeding tray by the fabric conveying device 312. The feeding drive can drive the feeding tray to move towards the capsule drum device 10 to convey the fabric 20 to the underside of the suction assembly 3132, thereby facilitating the suction of the suction assembly 3132. Optionally, the feeding drive can be configured as a cylinder, electric cylinder, etc.

[0031] Optionally, the suction assembly 3132 can be configured to include a suction cup, a suction cup lifting drive, and a suction cup horizontal drive. The suction cup can be a vacuum suction cup, magnetic suction cup, electrostatic suction cup, etc., as long as it can stably adsorb the material head of the covering fabric 20. The suction cup lifting drive and the suction cup horizontal drive are both connected to the suction cup drive. When the material head is conveyed by the feeding assembly 3131 to directly below the suction cup, the suction cup lifting drive drives the suction cup to descend, and the suction cup adsorbs the material head. After the suction cup stably adsorbs the material head, the suction cup horizontal drive drives the suction cup and the suction cup lifting drive to move above the capsule drum device 10 to wait for the material head to be bonded. Optionally, the suction cup lifting drive and the suction cup horizontal drive can be configured as a cylinder, an electric cylinder, etc.

[0032] In this embodiment, the cutting assembly 3134 includes a cutting blade for cutting the covering fabric 20 and multiple pressure blocks. Each pressure block is arranged along the conveying direction of the covering fabric 20, and pressure blocks are provided on both sides of the cutting blade. When the cutting blade cuts the covering fabric 20, the pressure blocks press the covering fabric 20 firmly. The cutting blade can be configured as a guillotine, spanning the width direction of the covering fabric 20 and positioned above it. When cutting the covering fabric 20 is required, the cutting blade falls to make the cut. When the cutting of the covering fabric 20 requires a certain angle, that is, when the cutting direction is not along the width direction of the covering fabric 20, the cutting blade can be adjusted to the corresponding angle. Pressure blocks are set on both sides of the cutter, and the pressure blocks are also set above the covering fabric 20. On the one hand, when the covering fabric 20 needs to be cut, the pressure blocks fall down and press down on the covering fabric 20 to prevent the covering fabric 20 from shifting when the cutter cuts it, thereby improving the accuracy of the cut, ensuring the flatness of the cut, and ensuring that the joint of the covering fabric 20 does not shake. On the other hand, after the covering fabric 20 is cut, the pressure blocks on both sides of the cutter press down on the tail of the first section of the covering fabric 20 and the head of the second section of the covering fabric 20 respectively to prevent the head and tail of the covering fabric 20 from lifting and shifting after the cutting. At the same time, when the feeding component 3131 conveys the head of the second section of the covering fabric 20 to the bottom of the adsorption component, the pressure blocks can press down on the head of the material to ensure the stability of the feeding component 3131 and prevent the covering fabric 20 from shifting on the feeding component 3131.

[0033] Preferably, the cutting assembly 3134 further includes a cutting blade drive and a pressure block drive. The cutting blade drive is connected to the cutting blade drive and cuts the covering fabric before it is fully attached to the capsule drum. The pressure block drive is connected to the pressure block drive and drives the pressure block to press the covering fabric firmly when the cutting blade cuts it. Thus, when the fixed-length covering fabric 20 is delivered to the designated position, the pressure block drive drives the pressure block to fall and press the covering fabric 20, and the cutting blade drive drives the cutting blade to fall and cut the covering fabric 20. The pressure blocks on both sides of the cutting blade can use the same pressure block drive or separate pressure block drive components. The pressure block drive can be a cylinder, electric cylinder, etc., as long as it can drive the pressure block to fall and press the covering fabric 20. It should be noted that the width direction of the covering fabric 20 refers to the direction perpendicular to the conveying direction of the covering fabric 20.

[0034] Optionally, the pressure roller assembly 3133 may include a pressure roller and a pressure roller drive component. The pressure roller drive component is connected to the pressure roller drive and can be configured as a cylinder, electric cylinder, etc. The pressure roller drive component can drive the pressure roller to approach the capsule drum device 10 to press the covering fabric 20. The pressure roller can be configured as a cylinder and can be rotated. The outer peripheral side of the pressure roller rolls the covering fabric 20. Preferably, the axial length of the pressure roller is not less than the width of the covering fabric 20 to improve the pressing quality of the covering fabric 20. After the covering fabric 20 is attached to the capsule drum device 10, the pressure roller moves away from the capsule drum device 10 under the drive of the pressure roller drive component to achieve avoidance.

[0035] In this embodiment, the fabric feeding rack further includes a pressing device 314, which is located at the axial end face of the capsule drum device 10. The pressing device 314 includes a rotatably configured pressing arm that can swing to the circumferential side of the capsule drum device 10 and press the fabric 20, thereby improving the stability and efficiency of the fabric 20 bonding, reducing the displacement and loosening of the fabric 20 during the bonding process, and ensuring the stable bonding of the fabric 20 on the capsule drum device 10. Specifically, the pressing device 314 can be disposed on the capsule drum device 10 and rotate synchronously with the rotation of the capsule drum device 10. When the adsorption component delivers the material head to the capsule drum device 10, the pressing arm swings to the material head of the wrapping fabric 20 and presses down the front end of the material head to stably fix the material head onto the capsule drum device 10. When the capsule drum device 10 rotates, the pressing arm rotates synchronously, so that the pressing device 314 can always press the material head tightly during the entire bonding process of the wrapping fabric 20, thereby ensuring reliable bonding of the material head, preventing the material head from shifting or falling off, and facilitating the bonding of the material tail with the material head when the wrapping fabric 20 approaches the material head, avoiding wrinkles. Moreover, this method of fixing the material head is beneficial for saving space and simplifying the structure of the wrapping fabric supply rack.

[0036] Preferably, the pressing device 314 further includes a pressing drive and a pressing drive. The pressing arm can be cylindrical to facilitate pressing down on the covering fabric 20. Both the pressing drive and the pressing drive are driven to the pressing arm. The pressing drive can drive the pressing arm to swing to the circumferential side of the capsule drum device 10, and the pressing drive can drive the pressing arm to press the covering fabric 20. When the pressing device 314 is not working, the axial direction of the pressing arm is set along the tangent of the capsule drum device 10 to avoid other components. When the material head is conveyed to the capsule drum device 10, the pressing drive drives the pressing arm to swing ninety degrees so that the axial direction of the pressing arm is parallel to the width direction of the covering fabric 20 and located above the covering fabric 20 to facilitate pressing down on the covering fabric 20. After the pressing device 314 has finished working, the pressing drive drives the pressing arm to swing back until the axial direction of the pressing arm is parallel to the tangent of the capsule drum device 10. In this embodiment, when the bonding device 313 bonds the covering fabric 20, the material head is located above the capsule drum. Therefore, the pressing device 314 is correspondingly located above the capsule drum device 10. When the pressing arm swings above the covering fabric 20, the pressing drive drives the pressing arm to fall onto the surface of the material head, so as to stably bond the material head to the capsule drum device 10 and prevent it from falling off during the rotation of the capsule drum device 10. Optionally, the pressing drive and the pressing drive can be set as a cylinder, servo motor, cam transmission, or other drive structure, which can realize the swing and pressing of the pressing device 314. Of course, depending on the actual situation, the pressing device 314 can also be set at other positions around the capsule drum device 10, as long as the pressing arm can press and fix the covering fabric 20.

[0037] In this embodiment, the fabric feeding rack also includes a length-fixing device 315. The length-fixing device 315 is located above the fabric conveying device 312 and measures the length of the fabric 20 to achieve precise control of the fabric 20's length, ensuring that the fabric 20's length meets requirements and reducing waste, thus lowering costs. Considering that the bonding device 313 is located near the capsule drum device 10 and has limited space, the length-fixing device 315 is positioned above the fabric conveying device 312. The length-fixing device 315 provides a fixed length of fabric 20, which is then conveyed by the fabric conveying device 312 to the bonding device 313, providing an accurate cutting position for the cutting device to cut the fabric 20. Optionally, the length-fixing device 315 can be a servo motor, which offers high precision and rapid response, providing both length measurement and fabric conveying functions.

[0038] In this embodiment, along the conveying direction of the fabric 20, the bonding device 313 is movably arranged relative to the fabric conveying device 312. The fabric feeding rack also includes an adjustment component 316, which is arranged between the fabric conveying device 312 and the bonding device 313. The bonding device 313 moves laterally relative to the fabric conveying device 312 through the adjustment component 316 to adjust the position of the fabric 20 material head falling on the capsule drum device 10. In this way, on the one hand, along the conveying direction of the wrapping fabric 20, the feeding component 3131 of this embodiment can be movably set relative to the wrapping fabric conveying device 312, so that the feeding component 3131 can convey the wrapping fabric 20 to the bottom of the adsorption component. On the other hand, by adjusting the component 316, the lateral position of the bonding device 313 can be moved as a whole. That is, by adjusting the component 316, the position of the feeding component 3131 is moved, and the adsorption component 3132, the pressure roller component 3133, the cutting component 3134 and the wrapping fabric 20 move laterally in sync. This allows the material head of the wrapping fabric 20 to be accurately bonded to the designated position on the capsule drum device 10, avoiding the wrapping fabric 20 from shifting and causing subsequent process operation failures, thereby improving the accuracy and efficiency of the wrapping fabric 20 bonding. Moreover, when it is necessary to adjust the bonding position of the wrapping fabric 20 and the tire bead, the position of the wrapping fabric 20 wrapped on the capsule drum device 10 can be easily adjusted by adjusting the bonding device 313.

[0039] Optionally, the adjustment component 316 may include structures such as an adjustment drive and an adjustment guide rail. An adjustment guide rail is provided between the bonding device 313 and the fabric conveying device 312, with the extension direction of the adjustment guide rail perpendicular to the conveying direction of the fabric 20. A servo drive or cylinder drive is used to drive the bonding device 313 to move laterally relative to the fabric conveying device 312, that is, to adjust the position of the bonding device 313 along the axial direction of the capsule drum device 10. Of course, the adjustment component 316 can also be configured with other structural forms, as long as it can achieve the overall lateral movement of the bonding device 313 to precisely control the lateral position of the fabric 20 on the capsule drum device 10. It should be noted that in this embodiment, "lateral" refers to being perpendicular to the conveying direction of the fabric 20.

[0040] In this embodiment, the fabric conveying device 312 is rotatably connected to the frame 311. The fabric feeding frame also includes a lifting component 317, which is driven to connect with the fabric conveying device 312 and drives the fabric conveying device 312 and the bonding device 313 to lift and swing synchronously. This allows the suction component 3132 to convey the fabric 20 to the capsule drum device 10. When the fabric 20 needs to be wrapped around the capsule drum device 10, the bonding device 313 can swing downward to accurately bond the fabric 20 to the outer periphery of the capsule drum device 10. After the fabric 20 is bonded, the bonding device 313 is driven to swing upward to avoid the tire bead placement process.

[0041] In this embodiment, the lifting assembly 317 may include a rotating shaft and a lifting cylinder. Both the rotating shaft and the lifting cylinder are disposed between the fabric conveying device 312 and the frame 311, and are arranged along the conveying direction of the fabric 20. When the cylinder rod of the lifting cylinder extends, it lifts the fabric conveying device 312, causing the rotating shaft to rotate. This keeps the height of the end of the fabric conveying device 312 away from the capsule drum device 10 constant, while the end closer to the capsule drum device 10 rises. This causes the fabric conveying device 312 to move the bonding device 313 away from the capsule drum device 10. When the cylinder rod of the lifting cylinder retracts, the end of the fabric conveying device 312 closer to the capsule drum device 10 descends, causing the bonding device 313 to descend as well. This allows the bonding device 313 to abut against the outer peripheral surface of the capsule drum device 10, thus bonding the fabric 20 to the outer peripheral surface of the capsule drum device 10. Optionally, the lifting cylinder may be replaced by an electric cylinder, servo motor, or other drive mechanism. Of course, the lifting component 317 can also adopt other structural forms, as long as it can meet the requirements of the bonding device 313 approaching and moving away from the capsule drum device 10. For example, it can also not adopt the swing motion form, but can also set a lifting cylinder at the rotating shaft, so that the lifting cylinder can drive the cloth conveying device 312 to lift as a whole. When the bonding device 313 drops to a certain height, the end of the bonding device 313 that is close to the capsule drum device 10 can bond the cloth 20 to the capsule drum device 10.

[0042] In this embodiment, the fabric conveying and bonding process includes: the fabric conveying device 312 conveys the fabric 20 to the bonding device 313; the bonding device 313 rotates and bonds the beginning of the fabric 20 to the capsule drum device 10; the capsule drum device 10 rotates to bond the fabric 20; before the bonding of the fabric 20 is completed, the cutting component 3134 moves and cuts the fabric 20; the capsule drum device 10 continues to rotate until the end of the material is bonded. Through the coordinated action of the fabric conveying device 312 and the cutting component 3134, the precise bonding and cutting of the fabric 20 is achieved, ensuring that the length of the fabric 20 meets production requirements; and the rotation of the bonding device 313 ensures that the fabric 20 can be accurately bonded to the capsule drum.

[0043] In this embodiment, the fabric conveying and bonding process further includes: when the fabric 20 is conveyed to the bonding device 313, the feeding component 3131 drives the fabric head of the fabric 20 to be conveyed a predetermined distance toward the capsule drum device 10; the suction component 3132 sucks up the fabric head and conveys it to the capsule drum device 10; the pressure roller component 3133 operates to press the fabric 20 onto the capsule drum device 10; and the capsule drum device 10 rotates to bond the fabric 20. The feeding component 3131 conveys the fabric head of the fabric 20 to the capsule drum device 10 to facilitate bonding between the fabric 20 and the capsule drum device 10. During the bonding process, the pressure roller component 3133 continuously presses the fabric 20, thereby ensuring the bonding quality between the fabric 20 and the capsule drum device 10.

[0044] In this embodiment, the fabric conveying and bonding process further includes: when the suction assembly 3132 picks up the material head and conveys it to the capsule drum device 10, the pressing device 314 is activated, and the pressing arm swings to the material head and presses the material head firmly onto the capsule drum device 10. The pressing device 314 ensures reliable bonding between the material head and the capsule drum device 10, preventing the material head from falling off or shifting.

[0045] The overall usage process of the fabric feeding rack in this embodiment is as follows: 1. Conveying and bonding the fabric 20: A fixed-length device 315 is provided above the fabric conveying device 312 of the fabric feeding rack, so as to convey a fixed length of fabric 20 to the bonding device 313; when the material head reaches the feeding component 3131 of the bonding device 313, the feeding component 3131 drives the fabric 20 to move towards the capsule drum device 10, so as to convey the material head of the fabric 20 to the underside of the adsorption component, and the adsorption component falls and adsorbs the material of the fabric 20. The head is then conveyed to the capsule drum device 10 by the adsorption component, which drives the wrapping cloth 20 to move closer to the capsule drum device 10. Subsequently, the lifting component 317 drives the wrapping cloth conveying device 312 to move the bonding device 313 downwards to bond the head of material to the capsule drum device 10. The pressing device 314 swings above the head of material and moves downwards to move closer to the head of material, stably fixing the head of material to the capsule drum device 10. Then the capsule drum device 10 begins to rotate, and the head of material rotates synchronously with the capsule drum device 10. After the capsule drum device 10 rotates at a small angle, the pressure roller assembly 3133 lowers the pressure roller to press the wrapping fabric 20, so that the wrapping fabric 20 can be stably wound around the capsule drum device 10. When the wrapping fabric 20 approaches a fixed length, the cutting assembly 3134 cuts the wrapping fabric 20. After the cutter cuts the wrapping fabric 20 that is being bonded, the feeding assembly 3131 moves towards the capsule drum device 10, conveying the material head of the next section of wrapping fabric 20 to below the suction assembly 3132. The approaching fixed length here can be set according to the actual situation, for example, setting it to approach a fixed length. The fixed length is 80% or 90% of the fixed length, etc.; the capsule drum device 10 continues to rotate, and the tail of the wrapping cloth 20 is smoothly rolled onto the capsule drum device 10 and pressed by the pressure roller assembly 3133 at the joint of the head and tail of the material; then the pressure roller assembly 3133 is lifted, and the pressure arm of the pressing device 314 swings back to be parallel to the tangent of the capsule drum device 10 to avoid the position above the wrapping cloth 20. The lifting assembly 317 drives the wrapping cloth conveying device 312 to drive the bonding device 313 to rise away from the capsule drum device 10.

[0046] It should be noted that "multiple" in the above embodiments refers to at least two.

[0047] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0048] 1. This solves the problem of unstable overlap between the front and back ends of the fabric in existing technologies;

[0049] 2. In this embodiment, the fabric feeding rack can first attach the end of the fabric to the capsule drum device. At this time, the fabric is not cut, which can ensure the stability of the fabric attachment position and avoid failures such as the end of the fabric falling off after being cut. When the fabric is attached to a predetermined distance but not completely attached to the capsule drum device, the cutting component cuts the fabric being attached, thus forming the end of the fabric being attached and the beginning of the next section of fabric. Since the distance between the cutting point and the capsule drum device is short at this time, the cutting component can cut the fabric being attached smoothly, and the end of the cut fabric can be attached smoothly to the capsule drum device, thereby reducing the shaking during the fabric cutting process, ensuring the flatness of the interface, and ensuring the accuracy of the attachment position of the fabric on the capsule drum device, avoiding the end of the fabric from curling or wrinkling. In this way, the stability of the fabric attachment process and the stability of the attachment of the end and the end are conducive to improving the overlap effect of the end and the end, avoiding problems such as overlap failure.

[0050] 3. The structure is simple and easy to operate. No additional positioning and conveying mechanisms are required. Compared to traditional fabric feeding devices that first cut the fabric to a fixed length and then attach it to the capsule drum device, the fabric feeding frame in this embodiment can directly feed the fabric to the feeding frame via the fabric guiding mechanism. This saves the intermediate process of conveying and positioning the cut fabric to a fixed length, thereby reducing the probability of fabric deviation and improving the accuracy of the fabric's attachment position on the capsule drum device.

[0051] It also simplifies the structure of the fabric feeding rack.
