Abstract
Description
Technical Field
[0001] This application relates to the field of duct protection technology, and in particular to a duct protection structure. Background Technology
[0002] In industries such as chemical fibers and textiles, the yarn transport system is a crucial link in ensuring production efficiency and product quality. In this field, with technological advancements, the level of automation in equipment is constantly increasing, while the safety requirements for operators are also becoming increasingly stringent. For example, in equipment such as drawing machines, multiple sets of high-speed rotating drawing rollers stretch the yarn bundle, thereby improving the quality of the yarn bundle and achieving efficient production. However, during the operation of these devices, the safety of operators has gradually become a major concern.
[0003] In existing technologies, to prevent operators' hands from getting caught in the drafting rollers of the drafting machine, protective plates are typically installed for safety protection; see reference Figure 1 The protective plate 1 is installed on the frame of the drawing machine and is located at the front end of the filament traction direction, and the protective plate 1 is located above the guide plate 41 of the frame 4; the protective plate 1 prevents limbs from entering the danger zone by limiting the filament gap between itself and the guide plate 41.
[0004] However, during the fiber bundle raising process, the individual fiber bundles are knotted to facilitate simultaneous stretching and winding. However, the narrow gap in the fiber path makes it difficult for the knots to pass through, and they are prone to getting stuck. If each fiber bundle is stretched separately, the efficiency is low. If the gap in the fiber path is too large, it compromises operator safety. Therefore, a structure is needed that can flexibly adjust the gap between the protective plate and the fiber guide table to improve the convenience of fiber bundle transmission while ensuring operator safety. Utility Model Content
[0005] In order to adjust the gap between the protective plate and the wire guide table, this application provides a wire guide protection structure.
[0006] The silk duct protection structure provided in this application adopts the following technical solution:
[0007] A wire guide protection structure is installed on a frame and includes a protective plate, an adjusting rod, and a fixing component. The adjusting rod is installed on the upper surface of the wire guide platform. The protective plate has an adjusting hole, and the adjusting rod is slidably connected to the inner wall of the adjusting hole. The fixing component is used to fix the adjusting rod and the inner wall of the adjusting hole.
[0008] By adopting the above technical solution, the fixing of the adjusting rod and the fixing component allows for convenient adjustment of the gap between the protective plate and the frame. This structure not only meets the requirement of smooth wire passing through but also ensures effective protection of the operator's hands. Simultaneously, the adjusting rod allows the protective plate to slide relative to the frame without requiring complex modifications to the drawing machine, thereby reducing costs and improving practicality.
[0009] Optionally, the fixing component includes a first threaded portion disposed on the outer wall of the adjusting rod and a second threaded portion disposed on the inner wall of the adjusting hole, the first threaded portion and the second threaded portion cooperating with each other; the wire guide table is provided with a guide rod, and the protective plate is provided with a guide hole for the guide rod to be inserted.
[0010] By adopting the above technical solution, the cooperation between the first threaded part and the second threaded part enables the protective plate to move stably and be fixed along the adjusting rod, thereby achieving precise adjustment of the gap between the protective plate and the frame. This ensures that the wire knots can pass through smoothly and provides effective protection for the hands when needed. The setting of the guide rod and guide hole further improves the stability of the protective plate during movement, avoiding the problem of protection failure or wire bundle transmission obstruction caused by deviation.
[0011] Optionally, the end of the adjusting rod away from the guide wire stage is covered with a rubber sleeve.
[0012] By adopting the above technical solution, the rubber sleeve covering the end of the adjusting rod away from the frame increases the friction when the operator rotates the adjusting rod, thus facilitating the operator to adjust the adjusting rod; at the same time, the rubber sleeve has a certain anti-slip property, which can effectively prevent the operator's hand from slipping during the adjustment process and improve the stability of the adjustment.
[0013] Optionally, the fixing component includes a fixing block and a spring. The outer wall of the adjusting rod has a movable groove, and the fixing block is movably installed in the movable groove. The inner wall of the adjusting hole has a first insertion groove and a second insertion groove for the fixing block to be inserted. The two ends of the spring are respectively connected to the fixing block and the movable groove, and the elastic force of the spring is used to drive the fixing block to move toward the side away from the movable groove.
[0014] The upper surface of the adjusting rod is provided with an unlocking groove that communicates with the movable groove. An unlocking rod is slidably installed in the unlocking groove, and one end of the unlocking rod is connected to the fixed block.
[0015] When the fixing block is inserted into the first insertion slot, the gap between the protective plate and the wire guide is at its minimum; when the fixing block is inserted into the second insertion slot, the gap between the protective plate and the wire guide is at its maximum.
[0016] By adopting the above technical solution, the spring force drives the fixing block to insert into the first or second insertion slot, thereby switching between the minimum and maximum gaps between the protective plate and the frame, respectively. When the fixing block is inserted into the first insertion slot, the minimum gap between the protective plate and the frame can effectively prevent the operator's hand from being caught, ensuring operational safety.
[0017] When the fixing block is inserted into the second insertion slot, the maximum gap between the protective plate and the frame provides sufficient space for the wire knots to pass through, preventing the knots from getting stuck and improving the wire bundle drawing efficiency. Furthermore, this structure is simple and reliable, allowing operators to flexibly adjust the gap size according to actual needs.
[0018] Optionally, the fixing component further includes a support plate disposed on the frame, wherein when the protective plate abuts against the support plate, the fixing block is inserted into the first insertion slot.
[0019] By adopting the above technical solution, the support plate can provide stable support for the protective plate, ensuring that the protective plate remains horizontal and stable when adjusted to the minimum gap, thereby effectively preventing the problem of unstable filament transmission caused by the shaking or tilting of the protective plate.
[0020] Optionally, a cushioning pad is provided on the upper surface of the support plate.
[0021] By adopting the above technical solution, the buffer pad on the upper surface of the support plate can effectively reduce the rigid contact between the protective plate and the support plate, thereby reducing the wear caused by the collision and extending the service life of the structure.
[0022] Optionally, a weight-reducing groove is provided in the middle of the protective plate.
[0023] By adopting the above technical solution, the weight-reducing groove can effectively reduce the overall weight of the protective plate, thereby reducing the load-bearing requirements on the adjusting rod and frame, making the installation and disassembly process more convenient. In addition, the weight-reducing groove can also reduce material usage, lower production costs, and improve the lightweight design of the structure while ensuring protective functions.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. The cooperation between the adjusting rod and the fixing component allows for easy adjustment of the gap between the protective plate and the frame, enabling the structure to meet the requirement of smooth wire passing through while ensuring effective protection of the operator's hands. At the same time, the setting of the adjusting rod allows the protective plate to slide relative to the frame without the need for complex modifications to the drawing machine, thereby reducing costs and improving practicality.
[0026] 2. The support plate provides stable support for the protective plate, ensuring that the protective plate remains level and stable when adjusted to the minimum gap. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.
[0034] Example 1:
[0035] This application discloses a wire guide protection structure, which is installed on the frame 4 of the drawing machine and located at the front end of the first drawing roller of the drawing machine.
[0036] Reference Figure 2 A wire guide structure includes a protective plate 1, an adjusting rod 2, and a fixing component 3. A frame 4 is provided with a wire guide platform 41, and a guide rod 42 is vertically installed on the wire guide platform 41. The protective plate 1 has a guide rod 42 for insertion into a guide hole 11. The cooperation between the guide hole 11 and the guide rod 42 allows the protective plate 1 to slide vertically on the wire guide platform 41, thereby adjusting the distance between the protective plate 1 and the wire guide platform 41.
[0037] Reference Figure 3 and Figure 4In this embodiment, the wire guide table 41 has a circular cross-section, and a rotating seat 21 is welded to the upper surface of the wire guide table 41. The adjusting rod 2 is rotatably connected to the rotating seat 21. The protective plate 1 has an adjusting hole 12, which is inserted into the adjusting rod 2. The fixing component 3 is used to fix the guide rod 42 and the inner wall of the adjusting hole 12. The fixing component 3 includes a first threaded part 31 and a second threaded part 32. The first threaded part 31 is disposed on the outer wall of the adjusting rod 2, and the second threaded part 32 is disposed on the inner wall of the adjusting hole 12. The first threaded part 31 and the second threaded part 32 are threadedly engaged.
[0038] Reference Figure 3 The end of the adjusting rod 2 away from the rotating seat 21 is covered with a rubber sleeve 22. The rubber sleeve 22 increases the friction between the operator's hand and the adjusting rod 2, so as to facilitate the rotation of the adjusting rod 2.
[0039] The protective plate 1 has a weight-reducing groove 13 at one end. The weight-reducing groove 13 can reduce the weight of the protective plate 1, so as to facilitate the vertical sliding of the protective plate 1, reduce the amount of material used, and reduce production costs.
[0040] The implementation principle of Embodiment 1 of this application is as follows:
[0041] The engagement of the first threaded portion 31 and the second threaded portion 32, under the guidance of the guide rod 42, enables the protective plate 1 to slide vertically, thereby achieving precise adjustment of the gap between the protective plate 1 and the wire guide table 41. This ensures that the wire knot can pass through smoothly and provides effective protection for the hand when needed.
[0042] Meanwhile, the adjustment rod 2 and guide rod 42 allow the protective plate 1 to slide relative to the frame 4 without requiring complex modifications to the stretching machine, thereby reducing costs and improving practicality.
[0043] Example 2:
[0044] This application discloses a duct protection structure.
[0045] Reference Figure 5 The difference between Embodiment 2 and Embodiment 1 is that: one end of the adjusting rod 2 is fixed to the upper surface of the crossbeam, and the cross-section of the adjusting rod 2 is rectangular; the fixing component 3 includes a fixing block 33, a spring 34, a support plate 5, and an unlocking rod 35; the side wall of the adjusting rod 2 is provided with a movable groove 23, the fixing block 33 is slidably installed in the movable groove 23, and the inner wall of the adjusting hole 12 is provided with a first insertion groove 14 and a second insertion groove 15 for the fixing block 33 to be inserted.
[0046] When the fixing block 33 is inserted into the first insertion slot 14, the gap between the protective plate 1 and the frame 4 is the minimum; when the fixing block 33 is inserted into the second insertion slot 15, the gap between the protective plate 1 and the frame 4 is the maximum.
[0047] The two ends of the spring 34 are connected to the fixed block 33 and the movable groove 23 respectively. The elastic force of the spring 34 is used to drive the fixed block 33 to move away from the movable groove 23, so as to increase the stability of the fixed block 33 when it is inserted into the first / second insertion groove 15.
[0048] The upper surface of the adjusting rod 2 is provided with an unlocking groove 24 that communicates with the movable groove 23. The extension direction of the unlocking groove 24 is in the same direction as the sliding direction of the fixed block 33. One end of the unlocking rod 35 is connected to the fixed block 33, and the other end of the unlocking rod 35 passes through the unlocking groove 24 and is exposed to the outside. By operating the unlocking rod 35, the fixed block 33 can be moved in the movable groove 23.
[0049] The support plate 5 is set on the frame 4, and the extension direction of the support plate 5 is in the same direction as the extension direction of the wire guide table 41. When the support plate 5 abuts against the bottom of the protective plate 1, the fixing block 33 is inserted into the first fixing groove. The upper surface of the support plate 5 is provided with a buffer pad 51, which is made of rubber material, so that the protective plate 1 and the support plate 5 are flexibly connected.
[0050] The implementation principle of Embodiment 2 of this application is as follows:
[0051] When the fixing block 33 is inserted into the first insertion slot 14, the minimum gap between the protective plate 1 and the frame 4 effectively prevents the operator's hand from getting caught, ensuring operational safety. When the fixing block 33 is inserted into the second insertion slot 15, the maximum gap between the protective plate 1 and the frame 4 provides sufficient space for the wire knots to pass through, preventing the wire knots from getting too short and improving the wire bundle stretching efficiency. In addition, this structure is simple and reliable, and allows operators to flexibly adjust the gap size according to actual needs.
[0052] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
