Description

Technical Field

[0001] This utility model relates to tire processing and production, and more specifically, to a pull-out device and a rubber material correction device for correcting rubber material deviation. Background Technology

[0002] In the field of rubber compound processing, especially in the manufacturing of inner lining products, padding cloth correction is crucial for ensuring product quality and production efficiency. Most existing padding cloth correction technologies rely on pull-out rollers in the winding device to guide and position the padding cloth, maintaining its correct path during winding. However, after prolonged continuous operation, pull-out rollers are prone to bending deformation due to material fatigue, mechanical stress, or wear, causing the roller's axis to bend and directly affecting the padding cloth correction effect and the overall winding neatness. Utility Model Content

[0003] The main purpose of this invention is to provide a pull-out device and a rubber material correction device for correcting rubber material deviation, so as to solve the problem of misalignment at both ends of the pull-out roller caused by deformation of the pull-out roller after long-term use in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a pull-out device for correcting rubber material deviation is provided, comprising a bracket, a swing arm assembly, and a support device. The swing arm assembly includes a pull-out roller movably disposed therein, the pull-out roller having a first end and a second end arranged axially, the second end being a free end. A conveying channel for the rubber material to pass through is provided between the pull-out roller and a correction roller for correcting the deviation of the rubber material. The pull-out roller has an initial position for the rubber material to enter the conveying channel and a working position for tensioning the rubber material. The support device is movably connected to the bracket, and the support device is located at the second end. When the pull-out roller is in the working position, at least a portion of the support device is located below the free end and supports the pull-out roller.

[0005] Furthermore, the support device has a locking part that can be docked and locked with the free end. When the pull-out roller is in the working position, the free end is locked in the locking part.

[0006] Furthermore, the free end has a stop, and the support device has an annular structure as a locking part. The annular structure has a notch, and when the pull-out roller is in the working position, the stop enters the annular structure through the notch and is confined within the annular structure.

[0007] Furthermore, one of the annular structure and the stop has a limiting protrusion located on the rotation path of the annular structure or the stop relative to each other. When the pull-out roller is in the working position, the limiting protrusion abuts against the limiting position of the annular structure or the stop.

[0008] Furthermore, the annular structure is a semi-circular ring, the stop block is a semi-circular block, and when the pull-out roller is in the working position, the annular structure is located at the bottom of the stop block.

[0009] Furthermore, the support device also includes a locking drive, which is connected to the bracket and driven to the locking part. The locking drive is used to drive the locking part to rotate relative to the bracket.

[0010] Furthermore, the connection between the locking part and the bracket forms a first connection point, and the connection between the locking part and the locking drive forms a second connection point. The first connection point and the second connection point are located at the two ends of the locking part, respectively, and the locking drive drives the locking part to rotate around the first connection point.

[0011] Furthermore, the swing arm assembly also includes a swing arm and a swing arm drive. The swing arm is connected to the first end of the pull-out roller and is rotatably connected to the bracket. The swing arm drive is driven to the swing arm and drives the swing arm to switch the pull-out roller between the initial position and the working position.

[0012] Furthermore, the pull-out roller includes a roller shaft and a roller body. The roller shaft is connected to the swing arm. When the pull-out roller is in the working position, the roller shaft is in a limiting engagement with the support device. The roller body is sleeved on the roller shaft and is rotatably arranged relative to the roller shaft.

[0013] According to another aspect of the present invention, a rubber material correction device is provided, including the above-mentioned pull-out device for rubber material correction and a correction roller. The correction roller is connected to the bracket of the pull-out device, and there is a conveying channel for the rubber material to pass through between the correction roller and the pull-out roller of the pull-out device. The rubber material enters the conveying channel from the free end of the pull-out roller.

[0014] By applying the technical solution of this utility model, on the one hand, by setting a support device at the free end of the pull-out roller, the pull-out roller can be supported on the lower part of the free end when it is in the working position, so as to ensure that the free end can be stably supported, thereby ensuring the straightness of the pull-out roller axis and avoiding bending deformation of the pull-out roller under force. Moreover, the support device for the free end can also correct the bending deformation of the pull-out roller when it undergoes a certain degree of bending deformation, thereby facilitating the alignment and centering adjustment of the free end, and keeping the rubber material on the pull-out roller flat, thus ensuring the subsequent correction effect, reducing waste generation, ensuring the smooth operation of the production line, and improving the compactness and operational stability of the pull-out device. On the other hand, when the rubber material is in the conveying channel, the pull-out roller switches from the initial position to the working position, which can drive the rubber material to the working position, so that the rubber material can be conveyed to the correction roller with a certain tension, thereby ensuring the subsequent correction effect.

[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.

[0020] To address the problem of misalignment at both ends of the pull-out roller caused by deformation from long-term use in existing technologies, this invention provides a pull-out device and a rubber material correction device for correcting rubber material deviation.

[0021] like Figures 1 to 3The pull-out device for correcting rubber material deviation shown includes a bracket 10, a swing arm assembly 20, and a support device 30. The swing arm assembly 20 includes a pull-out roller 21 that is movably arranged. The pull-out roller 21 has a first end and a second end arranged axially, with the second end being a free end. There is a conveying channel for the rubber material 50 to pass through between the pull-out roller 21 and a correction roller 40 for correcting the deviation of the rubber material 50. The pull-out roller 21 has an initial position for the rubber material 50 to enter the conveying channel and a working position for tensioning the rubber material 50. The support device 30 is movably connected to the bracket 10 and is located at the second end. When the pull-out roller 21 is in the working position, at least a portion of the support device 30 is located below the free end and supports the pull-out roller 21.

[0022] In this embodiment, by positioning the support device 30 at the free end of the pull-out roller 21, the pull-out roller 21 is supported at the lower part of the free end when in the working position. This ensures stable support for the free end, maintaining the axial straightness of the pull-out roller 21 and preventing bending deformation under stress. Furthermore, the support device 30's support of the free end allows for correction of bending deformation of the pull-out roller 21 even if it undergoes a certain degree of bending deformation, thus facilitating free movement. The alignment and centering adjustment at the end ensure that the rubber material 50 on the pull-out roller 21 remains flat, thereby guaranteeing the subsequent correction effect, reducing waste generation, ensuring the smooth operation of the production line, and improving the compactness and stability of the pull-out device. On the other hand, when the rubber material 50 is in the conveying channel, the pull-out roller 21 switches from the initial position to the working position, which can drive the rubber material 50 to the working position, so that the rubber material 50 can be conveyed to the correction roller 40 with a certain tension, thereby ensuring the subsequent correction effect.

[0023] It should be noted that the rubber material 50 conveying channel in this embodiment has an inlet for the rubber material 50 to enter. Compared with the first end of the pull-out roller 21, the inlet is located on the side close to the first end of the pull-out roller 21. The rubber material 50 conveying device moves along the axial direction of the pull-out roller 21 and conveys the rubber material 50 from the inlet into the conveying channel. Then the pull-out roller 21 switches from the initial position to the working position and pushes the rubber material 50 to move synchronously to the working position during the switching process. This allows the rubber material 50 to maintain a certain tension during the subsequent conveying process, so that the correction roller 40 can perform correction when the rubber material 50 has a certain tension, which is beneficial to improving the correction effect of the subsequent correction roller 40. The adhesive material 50 in this embodiment is widely used in the adhesive material correction pull-out device, and is applicable to all inner lining trolley structures, including trolley structures with left material roll and right padding roll, right material roll and left padding roll, trolley structures with left upper material roll and right lower padding roll, and trolley structures with lower material roll and upper padding roll, etc. It is also applicable to the conveying of other adhesive materials 50.

[0024] In this embodiment, the support device 30 has a locking part 31, which is movably connected to the bracket 10. The locking part 31 and the free end can be docked and locked together. When the pull-out roller 21 is in the working position, the free end is locked to the locking part 31, thereby ensuring the stability of the pull-out roller 21 in the working position and avoiding deformation or displacement of the free end caused by the pulling force or other external forces during the conveying of the rubber material 50. When the pull-out roller 21 is switched from the working position to the initial position, the locking part 31 and the free end are unlocked, so that the free end can be disengaged from the locking part 31.

[0025] like Figure 3 As shown, in this embodiment, the free end has a stop 211, and the support device 30 has an annular structure as a locking part 31. The annular structure has a notch. When the pull-out roller 21 is in the working position, the stop 211 enters the annular structure through the notch and is confined within the annular structure, thereby locking the free end. Specifically, in this embodiment, when the stop 211 is located inside the annular structure, the notch of the annular structure is set to face upwards. This prevents the stop 211 from coming off due to the gravity of the free end, and also prevents the pull-out roller 21 from deforming and coming off due to the tension of the rubber material 50 during continuous conveying. This ensures the stability and straightness of the pull-out roller 21 when it is in the working position. Thus, before the pull-out roller 21 switches to the working position, the notch of the annular structure faces the free end. When the pull-out roller 21 switches to the working position, the annular structure rotates relative to the bracket 10, thereby changing the orientation of the notch and preventing the stop 211 from coming off. It should be noted that the direction of the notch in the annular structure should avoid the direction of the pulling force applied by the rubber material 50 to the pull-out roller 21, so as to prevent the pulling force applied by the rubber material 50 to the pull-out roller 21 from deforming and thus causing the free end to disengage from the notch. Of course, depending on actual needs, the locking fit between the free end and the locking part 31 can also adopt other structural forms. For example, the locking part 31 can also adopt a structure in which two semi-circular clamps are combined to lock the free end. When the free end needs to be disengaged from the locking part 31, the two semi-circular clamps open; when the free end needs to be locked, the two semi-circular clamps lock the free end in the clamps.

[0026] In this embodiment, one of the annular structure and the stop 211 has a limiting protrusion 311. The limiting protrusion 311 is located on the rotation path of the annular structure or the stop 211. When the pull-out roller 21 is in the working position, the limiting protrusion 311 abuts against and limits the annular structure or the stop 211, thereby improving the locking effect between the free end and the locking part 31 and preventing slight displacement of the free end due to changes in the tension of the rubber material 50. Specifically, as Figure 3As shown, in this embodiment, the limiting protrusion 311 is disposed on the annular structure. The limiting protrusion 311 protrudes towards the center of the annular structure and is located at the edge of the annular structure, thereby forming a hook-like structure that prevents the stop block 211 from dislodging from the edge of the annular structure. Thus, the locking part 31 not only supports the stop block 211 from below but also limits its movement, further preventing the stop block 211 from dislodging from the annular structure. Alternatively, the limiting protrusion 311 can be disposed on the stop block 211. When the limiting protrusion 311 is on the stop block 211, it protrudes away from the center of the annular structure, preventing the annular structure from rotating relative to the stop block 211 and thus preventing the stop block 211 from separating from the annular structure. Preferably, the limiting protrusion 311 is provided only on one side of the stop block 211 or only at one end of the annular structure, so that when the annular structure rotates relative to the bracket 10, it can disengage from the stop block 211 from the end away from the limiting protrusion 311, thereby unlocking the annular structure and the stop block 211.

[0027] In this embodiment, the annular structure is a semi-circular ring, and the stop block 211 is a semi-circular block. When the pull-out roller 21 is in the working position, the annular structure is located at the bottom of the stop block 211, thus giving the stop block 211 an arc-shaped edge. The annular structure also has an arc-shaped edge. When the stop block 211 is located inside the annular structure, the arc-shaped edge of the stop block 211 matches the arc-shaped edge of the annular structure, allowing the annular structure to evenly distribute the force applied to the locking part 31 from the free end along the arc-shaped edge, thereby reducing local stress concentration and achieving a reliable fit between the stop block 211 and the annular structure. Simultaneously, when the annular structure rotates relative to the stop block 211, it can rotate along the arc-shaped edge, thus achieving reliable unlocking of the stop block 211 and the annular structure. Since this embodiment provides a limiting protrusion 311 on the edge of the annular structure, when the annular structure rotates relative to the stop block 211, causing the annular structure to disengage from the stop block 211, the annular structure can rotate around the end where the annular protrusion is located, rotating away from the end of the annular protrusion, thereby unlocking the annular structure and the stop block 211.

[0028] In this embodiment, the support device 30 further includes a locking drive member 32, which is connected to the bracket 10 and drivenly connected to the locking part 31. The locking drive member 32 is used to drive the locking part 31 to rotate relative to the bracket 10, thereby realizing automatic control of the locking part 31 and improving operating efficiency and safety. Specifically, in this embodiment, the locking drive member 32 is disposed below the locking part 31, and is drivenly connected to the end of the locking part 31 away from the limiting protrusion 311. When the locking of the stop 211 and the annular structure is released, the locking drive member 32 drives the annular structure to the side away from the stop 211, that is... Figure 3 The downward movement of the pull roller 21 allows the stop block 211 to disengage from the notch in the annular structure, thereby enabling the pull roller 21 to move the rubber material 50 back to its initial position. When the pull roller 21 moves to the working position and it is necessary to lock the stop block 211 and the annular structure, the locking drive 32 moves the annular structure closer to the stop block 211. The stop block 211 enters the interior of the annular structure from the notch, so that one end of the annular structure is supported and fixed by the locking drive 32, and the other end is stopped by the limit protrusion 311, thereby locking the stop block 211 and the annular structure and preventing the pull roller 21 from bending and deforming due to displacement of the free end. Optionally, the locking drive 32 can be a cylinder, hydraulic cylinder, etc. In this embodiment, the locking drive 32 is a locking cylinder.

[0029] In this embodiment, a first connection point is formed at the connection between the locking part 31 and the bracket 10, and a second connection point is formed at the connection between the locking part 31 and the locking drive member 32. The first and second connection points are located at opposite ends of the locking part 31. The locking drive member 32 drives the locking part 31 to rotate around the first connection point, thereby achieving simple and effective rotation control of the locking part 31. Specifically, in this embodiment, the locking drive member 32 drives the locking part 31 to rotate, changing the orientation of the notch in the locking part 31, thereby achieving locking and unlocking of the locking part 31 and the stop block 211. When the locking part 31 and the stop block 211 are locked together in this embodiment, the connection between the first connection point and the second connection point is horizontal or forms a small angle with the horizontal plane, with the notch facing upward. When the stop block 211 disengages from the locking part 31, the annular structure rotates around the first connection point as the rotation center, and the second connection point rotates towards the direction closer to the bracket 10. This increases the angle between the line connecting the first connection point and the second connection point and the horizontal plane, and the notch also rotates to the side of the stop block 211 away from the bracket 10, so that the stop block 211 can be disengaged from the notch.

[0030] In this embodiment, the swing arm assembly 20 further includes a swing arm 22 and a swing arm drive 23. The swing arm 22 is connected to the first end of the pull-out roller 21 and is rotatably connected to the bracket 10. The swing arm drive 23 is drivenly connected to the swing arm 22 and drives the swing arm 22 to switch the pull-out roller 21 between the initial position and the working position, thereby achieving efficient and stable switching of the pull-out roller 21. Specifically, the swing arm 22 serves as a connecting bridge between the pull-out roller 21 and the bracket 10. Its rotatable connection design with the bracket 10 allows the pull-out roller 21 to flexibly switch between the initial position and the working position, adapting to the conveying requirements of the rubber material 50 under different working conditions. Figure 1 As shown, in this embodiment, the end of the swing arm 22 away from the pull-out roller 21 is rotatably connected to the top of the direct support, thereby driving the pull-out roller 21 to swing around the connection point between the swing arm 22 and the support 10, thus achieving the switching between the initial position and the working position. Simultaneously, this does not affect the entry of the rubber material 50 into the conveying channel from near the free end of the pull-out roller 21 along the axial direction of the pull-out roller 21. Optionally, the swing arm drive 23 can be a cylinder, hydraulic cylinder, etc. In this embodiment, the swing arm drive 23 is a swing arm cylinder. Of course, the pull-out roller 21 can also achieve the switching between the initial position and the working position through other connection methods, ensuring that the rubber material 50 can enter the conveying channel and that the pull-out roller 21 can drive the rubber material 50 to achieve position switching. For example, a connecting arm can be slidably connected to the support 10, and the connecting arm is connected to the first end of the pull-out roller 21, so that the connecting arm can achieve the switching between the initial position and the working position through sliding relative to the direct support.

[0031] In this embodiment, the pull-out roller 21 includes a roller shaft and a roller body. The roller shaft is connected to the swing arm 22. When the pull-out roller 21 is in the working position, the roller shaft is in a limiting fit with the support device 30. The roller body is sleeved on the roller shaft and is rotatably arranged relative to the roller shaft, so that when the rubber material 50 is conveyed on the pull-out roller 21, it can drive the roller body to rotate relative to the roller body, thereby reducing the friction between the rubber material 50 and the roller body, which is beneficial to improving the conveying efficiency.

[0032] This embodiment also provides a rubber material correction device, including the aforementioned pull-out device for rubber material correction and a correction roller 40. The correction roller 40 is connected to the support 10 of the pull-out device, and there is a conveying channel for the rubber material 50 to pass through between the correction roller 40 and the pull-out roller 21 of the pull-out device. The rubber material 50 enters the conveying channel from the free end of the pull-out roller 21, thereby forming an integrated rubber material 50 correction system, improving the overall performance and stability of the rubber material correction device. Specifically, the correction roller 40 and the pull-out roller 21 are spaced apart and arranged parallel to each other. When the pull-out roller 21 is in the working position, the correction roller 40 is located on the side of the pull-out roller 21 away from the support 10, and the height of the correction roller 40 is slightly higher than that of the pull-out roller 21. This facilitates the formation of a certain tension when the rubber material 50 is conveyed from the pull-out roller 21 to the correction roller 40, thereby facilitating the correction of the correction roller 40, ensuring that the rubber material 50 is neatly wound and that no waste rubber is generated. The conveying channel design between the correction roller 40 and the pull-out roller 21, in conjunction with the movable pull-out roller 21, allows the rubber material 50 to be directly conveyed into the conveying channel. Then, the pull-out roller 21 drives the rubber material 50 to the working position and continues to convey it to the correction roller 40 for correction. This achieves automatic conveying and automatic correction of the rubber material 50 without the need for manual intervention, which helps improve work efficiency. At the same time, the integrated shipping makes packaging convenient, and precise fixing and installation are easy.

[0033] Preferably, the angle between the upper and lower edges of the rubber material 50 on the straightening roller 40 is 90°-110°; the upper edge length of the rubber material 50 on the straightening roller 40 is 0.25-0.5 times the width of the rubber material 50; the lower edge length of the rubber material 50 on the straightening roller 40 is 1-1.5 times the width of the rubber material 50; to prevent the pull-out roller 21 from detaching, the force direction of the pull-out roller 21 is lower than the horizontal direction; the swing arm drive component 23 satisfies the force on the pull-out roller 21 and the rubber material 50 on the trolley; the locking drive component 32 satisfies the braking force on the pull-out roller 21 and the padding cloth on the trolley, and reserves a certain amount of abnormal tension. It should be noted that the width direction of the rubber material 50 is along the axial direction of the pull-out roller 21, and the length direction of the rubber material 50 is perpendicular to the axial direction of the pull-out roller 21.

[0034] It should be noted that when the pull-out roller 21 is in the initial position, the cylinder rod of the locking cylinder retracts, and the annular structure rotates around the first connection point as the cylinder rod opens. The stop block 211 leaves the interior of the annular structure, and the stop block 211 is unlocked from the annular structure. The cylinder rod of the swing arm cylinder extends, and the pull-out roller 21 is in the initial position.

[0035] To facilitate the distinction between the initial position and the working position of the pull-out roller 21, such as Figure 2 As shown, Figure 2 The pull-out roller 21 in the initial position and the pull-out roller 21 in the working position are shown at the same time. The pull-out roller 21 closer to the support 10 is the one in the working position, and the pull-out roller 21 farther away from the support 10 is the one in the initial position.

[0036] The pull-out device for correcting rubber material deviation in this embodiment further includes detection components, including a first detection component and a second detection component. The first detection component is located at the locking drive component 32, and the second detection component is located at the swing arm drive component 23. The first detection component is used to detect the extension and retraction of the cylinder rod of the locking cylinder, and the second detection component is used to detect the extension and retraction of the cylinder rod of the swing arm cylinder. Optionally, the detection frame can be a magnetic switch.

[0037] The working process of the rubber material correction device in this embodiment is as follows: Before the trolley conveying the rubber material 50 enters, the cylinder rod of the locking cylinder retracts, the notch of the annular structure faces the pull-out roller 21, and the cylinder rod of the swing arm cylinder extends, causing the pull-out roller 21 to swing to its initial position as the cylinder rod extends. After the trolley conveying the rubber material 50 enters the work station, that is, after the rubber material 50 enters the conveying channel, the cylinder rod of the swing arm cylinder retracts, driving the pull-out roller 21 to swing from the initial position to the working position. At the same time, the movement of the pull-out roller 21 causes the rubber material 50 to move synchronously to the working position. In other words, the swing of the pull-out roller 21 pulls the rubber material 50 out of the trolley. After the pull-out roller 21 swings to the working position, the rubber material 50 forms an angle with the upper and lower edges of the correction roller 40. Preferably, the angle range is 90°-110°, which provides the best correction effect for the rubber material 50. Then, the cylinder rod of the locking cylinder extends, and the annular structure rotates around the first connection point toward the stop 211 as the cylinder rod extends, locking the annular structure to the stop 211 to fix the free end. When the pull-out roller 21 has bent and deformed, the annular structure, through its contact with the stop 211 during movement, drives the free end to a position that straightens the pull-out roller 21, locking the free end in that position so that the pull-out roller 21 can remain straight. After the work is completed, the circulating trolley enters the previous process, ultimately achieving uninterrupted station-changing winding.

[0038] It should be noted that "multiple" in the above embodiments refers to at least two.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: 1. This solves the problem of misalignment at both ends of the pull-out roller caused by deformation due to long-term use in the existing technology; 2. By setting a support device at the free end of the pull-out roller, the pull-out roller can be supported on the lower part of the free end when it is in the working position, so as to ensure that the free end can be stably supported, thereby ensuring the straightness of the pull-out roller axis and avoiding bending and deformation of the pull-out roller under force. 3. The support device supports the free end, so that even if the pull-out roller undergoes a certain degree of bending deformation, the bending deformation of the pull-out roller can be corrected by the support device. This facilitates the alignment and centering adjustment of the free end, and keeps the rubber material on the pull-out roller flat, thereby ensuring the subsequent correction effect, reducing waste generation, ensuring the smooth operation of the production line, and improving the compactness and operational stability of the pull-out device.
