[0029] Example 1:
[0030] like Figures 1-3 As shown, this utility model provides a warp feeding device for FIBC production, including: an unwinding roller, a warp feeding roller 10, and a cleaning component. The unwinding roller is adapted to unwind warp yarn. The warp feeding roller 10 and the unwinding roller are spaced apart in the length direction. The warp feeding roller 10 is adapted to transport the warp yarn unwinding from the unwinding roller to the FIBC weaving device. The cleaning component is disposed between the unwinding roller and the warp feeding roller 10. The cleaning component has a movable cleaning part. The cleaning component is linked with the warp feeding roller 10 or the unwinding roller. The rotation of the warp feeding roller 10 or the unwinding roller drives the cleaning part to move, thereby achieving cleaning of the warp yarn.
[0031] In some embodiments, the unwinding roller is responsible for storing and releasing the warp yarns. The feed roller 10 and the unwinding roller are spaced apart in the length direction. The feed roller 10 is used to accurately transport the warp yarns released from the unwinding roller to the FIBC weaving device. The cleaning assembly is located between the unwinding roller and the feed roller 10. The cleaning assembly includes a movable cleaning part. The cleaning assembly is linked with the feed roller 10 or the unwinding roller so that when the feed roller 10 or the unwinding roller rotates, it can drive the cleaning part to move, thereby cleaning the passing warp yarns.
[0032] Understandably, through mechanical linkage design (such as gear, belt and other transmission methods), any action during the warp release process (such as the rotation of the unwinding roller or the rotation of the feed roller 10) can trigger the operation of the cleaning component. That is, whenever the warp is fed out, the cleaning component will be automatically activated. The cleaning part in the cleaning component can move under the drive of the feed roller 10 or the unwinding roller to effectively remove dust, impurities and other contaminants from the warp before it enters the weaving area, thus ensuring the weaving quality.
[0033] It is worth mentioning that, compared to the traditional method of fixing the brush head to clean the warp threads, the cleaning section of this application moves to clean the warp threads, resulting in a better cleaning effect. Of course, the cleaning section can be a simple brush head or other cleaning tools; there are no restrictions here.
[0034] According to the present invention, the warp feeding device for producing container bags effectively cleans the warp threads that are about to enter the weaving process through the activity of the cleaning unit, which can significantly reduce fabric defects caused by dust or impurities and improve the quality of the final product. Moreover, since the cleaning component is directly linked to the warp feeding roller 10 or the unwinding roller, the cleaning process is automated, and the cleaning of the warp threads can be completed without additional manual intervention, thereby improving production efficiency.
[0035] Example 2:
[0036] Based on Embodiment 1, this embodiment features a cleaning unit adapted to move relative to the warp threads in the width direction. The feed roller 10 or unwind roller rotates to drive the cleaning unit to move in the width direction to clean the warp threads. It is understood that the cleaning unit can not only perform basic cleaning actions, but also move relative to the warp threads in the width direction. That is, the cleaning unit can move back and forth along the transverse direction of the warp threads (i.e., perpendicular to the warp thread length), thereby achieving thorough cleaning of the warp threads. This results in a more thorough removal of dust, impurities, and other contaminants, improving cleaning efficiency and effectiveness, reducing weaving defects caused by uncleaned warp threads, and ultimately improving the quality of the final product.
[0037] According to some embodiments of the present invention, the warp feed wheel 10 is coaxially provided with a first bevel gear 21, and the cleaning assembly includes a second bevel gear 22, an input gear 23, and an output rack 24. The second bevel gear 22 meshes with the first bevel gear 21, the input gear 23 is coaxially connected with the second bevel gear 22, the output rack 24 extends in the width direction, and the output rack 24 meshes with the input gear 23. The input gear 23 rotates to drive the output rack 24 to move in the width direction, and the cleaning part is connected to the output rack 24.
[0038] Understandably, when the warp feed wheel 10 begins to rotate, the first bevel gear 21 on its shaft also rotates. The first bevel gear 21 drives the second bevel gear 22 to rotate (transmitting rotational motion and potentially changing the direction of rotation through the meshing of the bevel gears). The rotation of the second bevel gear 22 further drives the input gear 23, which is coaxial with it, to rotate. The input gear 23 meshes with the output rack 24, converting the rotational motion of the input gear 23 into the linear motion of the output rack 24. Thus, as the output rack 24 moves in the width direction, the cleaning part connected to the output rack 24 also moves accordingly, thereby achieving comprehensive cleaning of the warp threads.
[0039] Example 3:
[0040] Based on Embodiment 2, the outer peripheral wall of the input gear 23 is provided with an installation area and a blank area extending in the circumferential direction. The installation area is provided with a plurality of meshing teeth 231, which can selectively mesh with the output rack 24. The cleaning component also includes a reset member, which is connected to the output rack 24 and is adapted to drive the output rack 24 to reset.
[0041] In some embodiments, the reset element is constructed as a spring 32. The outer peripheral wall of the input gear 23 is divided into a mounting area and a blank area in the circumferential direction. The mounting area is provided with a plurality of meshing teeth 231, which can mesh with the output rack 24. When the input gear 23 rotates to the mounting area and is directly opposite the output rack 24, the meshing teeth 231 cooperate with the output rack 24 to drive the output rack 24 to move in the width direction. At this time, the spring 32 is stretched. The blank area is not provided with meshing teeth 231. When the input gear 23 rotates to the blank area and is directly opposite the output rack 24, the input gear 23 will not drive the output rack 24 to move. At this time, the reset force of the spring 32 can drive the output rack 24 to reset.
[0042] Therefore, the above-mentioned setup enables the cleaning unit to move back and forth in the width direction, ensuring full coverage and effective cleaning of the warp surface, reducing the impact of dust and impurities. Moreover, combined with the function of the reset component, the entire cleaning process can be completed automatically without manual intervention, improving the level of automation and efficiency of production.
[0043] According to some embodiments of this utility model, in the circumferential direction of the input gear 23, the length of the mounting area is c1, and the length of the blank area is c2, satisfying: 0.3≤c1 / c2≤0.5. It can be understood that by setting 0.3≤c1 / c2≤0.5, sufficient time can be allowed for the reset component to work while ensuring sufficient stroke for effective cleaning, thus extending the working time of the reset component (the reset component can also drive the output rack 24 to reciprocate in the width direction during its elastic movement). Furthermore, the contact time between the meshing teeth 231 and the output rack 24 can be reduced, thereby extending the service life of the input gear 23 and the output rack 24.
[0044] Example 4:
[0045] Based on Embodiment 1, in this embodiment, the cleaning section can selectively rotate relative to the warp, and the warp feed roller 10 or the unwinding roller rotates to drive the cleaning section to rotate, thereby cleaning the warp. In some embodiments, when the warp feed roller 10 or the unwinding roller rotates, its power is transmitted to the cleaning section through a transmission device, thereby driving the cleaning section to rotate to clean the warp.
[0046] Understandably, the rotating action of the cleaning section can more effectively remove various contaminants adhering to the warp surface, thereby improving cleaning efficiency and quality. Moreover, due to the rotation of the cleaning section, it can distribute pressure more evenly when in contact with the warp, reducing warp damage caused by excessive local friction and extending the service life of the warp.
[0047] According to some embodiments of the present invention, the cleaning component includes: a first synchronous pulley 41, a synchronous belt 23, and a rotating shaft 24. The first synchronous pulley 41 is coaxially connected to the warp feed wheel 10. One end of the synchronous belt 23 is engaged with the first synchronous pulley 41, and the other end of the synchronous belt 23 is engaged with a second synchronous pulley 42. The rotating shaft 24 is coaxially connected to the second synchronous pulley 42, and a cleaning part is provided on the outer peripheral wall of the rotating shaft 24.
[0048] Understandably, when the warp feed wheel 10 starts working and rotates, the first synchronous pulley 41, which is coaxial with the warp feed wheel 10, also rotates. The first synchronous pulley 41 transmits the rotational motion to the second synchronous pulley 42 through the synchronous belt 23. The second synchronous pulley 42 rotates and transmits its rotational force to the rotating shaft 24 through a coaxial connection. The rotation of the rotating shaft 24 causes the cleaning part on its outer peripheral wall to rotate. During the rotation, the cleaning part contacts and cleans the warp threads that are being unwound or conveyed, effectively removing dust, impurities and other contaminants.
[0049] It is worth mentioning that the warp feed wheel 10 rotates to drive the cleaning section to rotate. Therefore, the faster the warp feed wheel 10 rotates (the faster the production speed and the faster the warp feed speed), the faster the cleaning section rotates; similarly, the slower the warp feed wheel 10 rotates (the slower the production speed and the slower the warp feed speed), the slower the cleaning section rotates. Thus, through the above settings, the cleaning section can automatically adjust its rotation speed according to the production rhythm, so as to effectively clean the warp threads under different production rhythms.
[0050] According to some embodiments of the present invention, the warp feeding device further includes: a mounting shell 50 and an inspection door. The mounting shell 50 is provided with a mounting cavity. The unwinding roller and the warp feeding roller 10 are rotatably disposed in the mounting cavity. The cleaning component is disposed in the mounting cavity and located between the unwinding roller and the warp feeding roller 10. The top of the mounting shell 50 is provided with an inspection port facing the cleaning component. The inspection door is rotatably connected to the mounting shell 50. The inspection door can be rotated to selectively open or close the inspection port.
[0051] In some embodiments, the mounting housing 50 provides a protective outer shell with an internal mounting cavity for accommodating key components such as the unwinding roller, the warp feed roller 10, and the cleaning assembly. The top of the mounting housing 50 has an access port directly facing the location of the cleaning assembly, allowing technicians to directly access the parts that need to be inspected or maintained. Technicians can open or close the access port as needed by rotating the access door, allowing them to easily access the interior of the warp feed device and perform necessary inspections, cleaning, or replacement of parts without disassembling the entire warp feed device.
[0052] During normal operation, the housing 50 is closed to protect the internal components from the influence of the external environment (such as dust, moisture, etc.) and to provide a stable working space for each component. When it is necessary to inspect, adjust or repair the cleaning components or other internal components, simply open the access door to quickly access the part that needs to be treated.
[0053] It should be noted that the inner circumferential wall of the mounting cavity can form mounting and fixing points for the unwinding roller and the warp feed roller 10. Of course, the unwinding roller and the warp feed roller 10 can also be set in the mounting cavity by a specific mounting bracket, which is not limited here.
[0054] In some embodiments, when the cleaning assembly includes a second bevel gear 22, an input gear 23, and an output rack 24, the second bevel gear 22 is rotatably connected to the mounting housing 50 via a rotating rod 25, and a slide rail 31 extending in the width direction is provided inside the mounting cavity. Both ends of the slide rail 31 are connected to the mounting housing 50, and a slider is provided on the output rack 24. The slider is movably housed within the slide rail 31, thereby restricting the movement of the output gear and ensuring that the cleaning unit can move stably in the width direction. Of course, one end of the spring 32 is connected to the output gear, and the other end of the spring 32 is connected to the slide rail 31 or the mounting housing 50; this is not limited here.
[0055] In other embodiments, when the cleaning assembly includes a first timing pulley 41, a timing belt 23, and a rotating shaft 24, both ends of the rotating shaft 24 extend to be rotatably connected to the mounting housing 50.
[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
