Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and in particular to a feeding device for conveying the end of a strip and a tire strip length-fixing device containing the same. Background Technology

[0002] In the tire forming process, the tire carcass feeding system provides semi-finished components such as the sidewall, inner liner, and carcass cord to the forming drum, ensuring that these components fit accurately onto the drum. The tire carcass feeding system includes a carcass conveyor, an inner liner conveyor, and a sidewall fixed-length conveyor, among other semi-finished product feeding and conveying devices. Existing semi-finished product feeding and conveying devices typically perform fixed-length cutting of semi-finished products on a straight conveyor belt (fixed-length cutting refers to measuring and cutting continuous semi-finished products to the required length according to production needs). Because the semi-finished components are alternately transferred to the forming drum for tire forming, there is a waiting period after the fixed-length cutting on the semi-finished product feeding and conveying device.

[0003] After being cut to a fixed length, the semi-finished parts are waiting to be conveyed on the semi-finished product feeding and conveying device. Due to the influence of external temperature changes and the material's own characteristics (such as the inconsistent thickness on both sides of the tire sidewall and the material's own flow characteristics), the length and width of the semi-finished parts will expand or contract. This is especially true for the narrower tire sidewall material, which will affect the accuracy of the bonding.

[0004] To address the aforementioned issues, the applicant developed a circumferential tire strip length-fixing device for better length control of tire strips. After the strip has been lengthened on the circumferential device, a feeding device is needed to transfer the end of the strip (the end being either the head or tail) to the correct length. During use, the applicant found that when producing tires of different specifications, and the thickness of the strip varies, the position of the feeding mechanism needs repeated adjustments, resulting in lengthy changeover and debugging times. Therefore, it is necessary to develop a feeding device applicable to strips of varying thicknesses. Utility Model Content

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5As shown, this utility model discloses a feeding device 1 (hereinafter referred to as the feeding device) for conveying the end of a tire strip (the end of the strip includes a strip material head and / or a strip material tail). The feeding device 1 includes a support frame 10, a feeding drive mechanism 20 disposed on the support frame 10, and a feeding mechanism 30. The feeding mechanism 30 is connected to the feeding drive mechanism 20, and the feeding drive mechanism 20 is used to drive the feeding mechanism 30 to move. The feeding mechanism 30 includes a feeding mounting base 31, a picking drive source 32 fixed on the feeding mounting base 31, a picking mounting frame 33 driven by the picking drive source 32, a needle mechanism 34 disposed on the picking mounting frame 33, and an elastic mechanism 40. The picking mounting frame 33 can be movably disposed relative to the picking drive source 32 through the elastic mechanism 40, thereby driving the needle mechanism 34 to be movably disposed relative to the picking drive source 32. With the above configuration, when the feeding device grips strips of different thicknesses, the needle mechanism 34 is first driven by the feeding drive source 32 to descend and contact the strip on the fixed-length wheel 100 (which is used to fix and cut the strip to the correct length). Once the needle mechanism 34 can no longer descend after contacting the strip, the drive end of the feeding drive source 32 continues to move to a designated position. During this process, the needle mechanism 34 stops moving downwards via the elastic mechanism 40. This design is well-suited for gripping strips of different thicknesses and avoids collisions between the needle mechanism 34 and the fixed-length wheel 100 that supports the strip, thus preventing damage to the needle. When producing strips of different thicknesses, there is no need to change the feeding device, facilitating production.

[0023] Preferably, the needle mechanism 34 includes a retractable needle 341, which extends when it is necessary to fix and grasp the strip, and retracts when it is no longer necessary to fix and grasp the strip. The needle mechanism 34 is prior art and will not be described in detail here.

[0024] like Figure 3As shown, specifically, the elastic mechanism 40 includes an elastic mounting plate 41 disposed at the driving end of the material picking drive source 32. The material picking mounting frame 33 is movably disposed on the elastic mounting plate 41 via a first moving component 42 (a combination of slide rail and slider). It also includes a first connecting member 43 connected to the elastic mounting plate 41, and a second connecting member 44 connected to the material picking mounting frame 33. Furthermore, it includes an elastic element 45 connecting the first connecting member 43 and the second connecting member 44, making the distance between the first connecting member 43 and the second connecting member 44 adjustable. With the above configuration, during the material picking process, when the material picking drive source 32 drives the elastic mounting plate 41 downwards, causing the needle mechanism 34 to press down and contact the strip on the surface of the fixed-length wheel, when the material picking drive source 32 continues to drive the elastic mounting plate 41 downwards, the material picking mounting frame 33 is rigidly limited and remains stationary, no longer moving downwards. The elastic mounting plate 41 continues to move downwards relative to the material picking mounting frame 33, and the elastic element 45 is compressed.

[0025] After material handling is completed, the material handling drive source 32 drives the elastic mounting plate 41 to move upward, causing the compressed elastic element 45 to reset. This continues until the elastic element 45 returns to its free state, then drives the needle mechanism 34, which holds the strip, away from the fixed-length wheel 100, moving the end of the strip to a specified height. Through the aforementioned elastic mechanism 40, when the downward movement of the needle mechanism 34 is restricted, the relative movement of the material handling mounting frame 33 and the drive end of the material handling drive source 32 is achieved, thereby avoiding a hard collision between the needle mechanism 34 and the fixed-length wheel 100.

[0026] The elastic mechanism 40 also includes a limiting member 46 disposed on the elastic mounting plate 41. The limiting member 46 is disposed on the side of the elastic mounting plate 41 near the second connecting member 44 and is detachable from the material-picking mounting frame 33, used to limit the material-picking mounting frame 33. In use, the material-picking mounting frame 33 contacts the limiting member 46 by gravity. When the needle mechanism 34 contacts the strip and is rigidly limited by the fixed-length wheel 100, the material-picking drive source 32 drives the elastic mounting plate 41 to continue moving downward, thereby causing the limiting member 46 to move downward and separate from the material-picking mounting frame 33. Furthermore, the position of the material-picking mounting frame 33 relative to the elastic mounting plate 41 can be adjusted by adjusting the length of the limiting member 46.

[0027] Since the material handling mounting frame 33 and the second connecting member 44 are fixedly installed, after adjusting the position of the material handling mounting frame 33 by adjusting the length of the limiting member 46, in order to maintain the free state between the first connecting member 43 and the second connecting member 44, that is, the position of the elastic element 45 on the first connecting member 43 also needs to be adjusted. In order to cooperate with the position adjustment of the material handling mounting frame 33, an adjusting member 47 is also sleeved on the first connecting member 43. The adjusting member 47 is used to adjust the actual contact length between the first connecting member 43 and the elastic element 45. The elastic element 45 is disposed on the second connecting member 44 and the portion of the first connecting member 43 between the second connecting member 44 and the adjusting member 47.

[0028] It should be noted that, as Figure 4 As shown, when the needle mechanism 34 moves upward after fixing the strip to the surface of the fixed length wheel 100, during the process of separating the end of the strip from the fixed length wheel 100, that is, during the movement from point B to point C, the length between the strips DC (DC is the actual length of the strip when it is lifted to point C) may be greater than the length between the strips DB (DB is the length of the strip when it is at point B), which causes the strip to be pulled during the lifting process, thus causing the strip to be stretched and deformed. Therefore, in order to solve the above-mentioned technical problems, preferably, the setting direction of the material picking drive source 32 of this utility model is set at an obtuse angle to the horizontal transmission direction of the strip, so that the moving direction F1 of the material picking drive source 32 and the horizontal transmission direction F2 of the strip (referring to the horizontal direction of the previous process to the next process) are set at an obtuse angle α (α is greater than 90 degrees and less than 180 degrees). That is, the moving direction F1 of the material picking drive source 32 driving the needle mechanism is set at an obtuse angle α to the horizontal transmission direction F2 of the strip. When the needle mechanism 34 moves the strip from point B to point E, the length between the strip DE is less than the length between the strip DB, thereby avoiding the pulling force on the strip during the lifting process of the needle mechanism.

[0029] The feeding drive mechanism 20 of this utility model includes a feeding drive source 21 and a transmission mechanism 22 disposed on a support frame 10. The transmission mechanism 22 is driven by the feeding drive source 21. The feeding mechanism 30 is connected to the transmission mechanism 22. The feeding drive source 21 drives the transmission mechanism 22 to move, thereby driving the feeding mechanism 30 to move, realizing the feeding of the strip fixed on the feeding mechanism 30. Preferably, the transmission mechanism 22 is a combination of a synchronous belt and a synchronous pulley.

[0030] In actual material feeding, the feeding speed of the feeding mechanism 30 and the rotation speed of the fixed-length wheel 100 must match to complete the feeding process effectively; otherwise, technical problems such as failure to feed or stretching of the strip may occur. However, it is difficult to achieve a perfect match between the feeding speed and the rotation speed of the fixed-length wheel 100, so the feeding length needs to be minimized. Since the feeding device 1 transfers the strip on the fixed-length wheel 100 to a linear conveyor (not shown), and since the linear conveyor has a certain thickness, in order to bring the linear conveyor and the fixed-length wheel 100 as close as possible to each other and reduce the feeding length, the linear conveyor in the subsequent process is inclined. Therefore, the feeding path of the feeding mechanism 30 described in this utility model also needs to be inclined to match it.

[0031] Therefore, in order to achieve the inclined feeding of the strip by the aforementioned feeding mechanism, such as Figure 1 and 2 As shown, the transmission mechanism 22 of this utility model includes a first synchronous pulley 221, a second synchronous pulley 222, and a third synchronous pulley 223, and a first synchronous belt 224 arranged around the first synchronous pulley 221, the second synchronous pulley 222, and the third synchronous pulley 223. The line connecting the first synchronous pulley 221 and the second synchronous pulley 222 is at a certain angle to the horizontal direction F2, and the line connecting the second synchronous pulley 222 and the third synchronous pulley 223 is approximately parallel to the vertical direction F3. This results in the portion of the first synchronous belt 224 located between the first synchronous pulley 221 and the second synchronous pulley 222 being inclined. The portion of the first synchronous belt 224 between the feeding mechanism 30 and the first synchronous pulley 221 and the second synchronous pulley 222 is fixedly arranged. With the above arrangement, when the feeding drive source 21 drives the transmission mechanism 22 to move, it causes the feeding mechanism 30 to move at an incline to feed material.

[0032] The support frame 10 of this utility model includes a first support portion 11 and a second support portion 12. The first support portion 11 is arranged vertically, and the second support portion 12 is arranged at an obtuse angle to the first support portion 11. The second support portion is inclined upward relative to the horizontal conveying direction F2 of the strip. The feeding mounting seat 31 is movably mounted on the second support portion 12 by a second moving component 311 (such as a combination of a slide rail and a slider), and the feeding mounting seat 31 is fixedly mounted on a portion of the first synchronous belt 224 between the first synchronous pulley 221 and the second synchronous pulley 222 by a first fixing member 312. The driving end of the feeding drive source 21 is movably mounted on the first support portion 11 by a third moving component 211 (such as a combination of a slide rail and a slider), and the driving end of the feeding drive source 21 is fixedly mounted on a portion of the first synchronous belt 224 between the second synchronous pulley 222 and the third synchronous pulley 223 by a second fixing member 212. With the above configuration, when the feeding drive source 21 drives the first synchronous belt 224 to move, the first synchronous belt 224 drives the feeding mounting base 31 to move on the second support part 12, thereby driving the feeding mechanism 30 to move to feed materials.

[0033] like Figure 5 As shown, this utility model also provides a tire strip length-fixing device 1000 with a material delivery device, including a fixed frame 200, a rotating shaft 300 rotatably mounted on the fixed frame 200, a cylindrical length-fixing wheel 100 fixedly mounted on the rotating shaft 300, and a rotation drive source 400 fixedly mounted on the fixed frame 200. The rotation drive source 400 drives the rotating shaft 300 to rotate, thereby driving the length-fixing wheel 100 to rotate. It also includes the aforementioned material delivery device 1, which is mounted on the fixed frame 200 and is positioned opposite to the length-fixing wheel 100, such that the material delivery mechanism 30 is located above the length-fixing wheel 100, which facilitates the material delivery mechanism 30 to fix the end of the strip after length-fixing from the length-fixing wheel 100.

[0034] This utility model mainly provides a brand-new material feeding device 1. The material feeding mechanism 30, which is movably arranged relative to the material feeding drive mechanism 20, fixes and grips the end of the strip on the fixed length wheel 100, thereby making it more suitable for strips of different thicknesses. By setting the material picking drive source 32 at an obtuse angle to the horizontal transmission direction of the strip, the moving direction of the material picking drive source 32 is set at an obtuse angle to the horizontal transmission direction of the strip, thereby avoiding the force generated along the horizontal transmission direction of the strip during the process of the material feeding mechanism 30 lifting the strip upward, which would cause the strip to be pulled.
