Description

Technical Field

[0001] This utility model belongs to the technical field of surface treatment equipment for metal materials, and specifically relates to a bluing and rust prevention treatment device for end-hook type steel fibers. Background Technology

[0002] The bluing and rust prevention treatment device for end-hook steel fibers is an industrial equipment specifically designed to improve the corrosion resistance of steel fibers. This device uses a high-temperature oxidation process (bluing treatment) to form a dense oxide film layer on the surface of the steel fibers. Its core function is to achieve uniform rust prevention layer coverage on the complex geometry of end-hook steel fibers (such as the hooked areas).

[0003] Currently, during the bluing and rust prevention process, the hook-shaped steel fibers are prone to embedding into the mesh or seams of the conveyor belt due to their hook-like structure. With continuous operation, they gradually accumulate in the high-temperature section, forming an anchoring effect and causing localized blockage at the bottom of the fiber layer. This blockage problem is progressive, initially difficult to detect but worsening over time, and may eventually cause conveyor belt jamming, abnormal tension, or even motor overload and shutdown.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a bluing and rust-preventing treatment device for end-hooked steel fibers, comprising: The support mechanism 100 includes a support frame 110, a transmission assembly 120 disposed in the inner cavity of the support frame 110, a side plate 130 fixedly installed on the outside of the support frame 110, an adjustment channel 140 opened on the outside of the side plate 130, and a limiting groove 150 opened on the outside of the side plate 130. The guiding auxiliary mechanism 200 includes a fixed rod 210, a telescopic rod 220 fixedly installed at the bottom of the fixed rod 210, a bracket 230 movably sleeved on the outside of the telescopic rod 220, an adaptive adjustment component 240 disposed on one side of the bracket 230, a bearing seat 250 fixedly installed on the other side of the bracket 230, a support crossbar 260 hinged to the outside of the bearing seat 250, a limiting plate 270 hinged to the outside of the support crossbar 260, ceramic guide comb teeth 280 fixedly installed at the bottom of the support crossbar 260, and a movable component 290 disposed at the center of the bottom of the bracket 230.

[0019] The combination of the support frame 110 of the bearing mechanism 100 and the conveying component 120 enables stable conveying of steel fibers in high-temperature environments. The coordinated design of the side plate 130, the adjusting channel 140, and the limiting groove 150 provides a precise mechanical positioning basis for the subsequent adaptive adjustment component 240. The guide auxiliary mechanism 200, through the linkage of the fixed rod 210, the telescopic rod 220, and the adaptive adjustment component 240, enables the ceramic guide comb 280 to dynamically adapt to the arrangement requirements of steel fibers of different specifications. At the same time, the hinged structure of the support crossbar 260 and the limiting plate 270 effectively prevents the fibers from being hooked and deviated. The whole system forms a transmission system that combines rigid support and flexible adjustment.

[0020] Specifically, the adaptive adjustment component 240 includes a connecting rod 241 fixedly installed on the outside of the bracket 230, and a return spring 242 fixedly installed on the bottom of the connecting rod 241. The adaptive adjustment component 240 also includes a movable rod 243 sleeved in the inner cavity of the return spring 242, a support plate 244 fixedly installed on the bottom of the movable rod 243, and a slider 245 fixedly installed on the outside of the support plate 244. The connecting rod 241 is movably engaged in the inner cavity of the adjustment channel 140, and the slider 245 is movably engaged in the inner cavity of the limiting groove 150.

[0021] The adaptive adjustment component 240 uses an elastic connection between the connecting rod 241 and the return spring 242, which enables the bracket 230 to have an automatic reset function. When the thickness of the steel fiber stack changes, the spring deformation can absorb the impact force, avoiding fiber deformation or equipment damage caused by hard contact, significantly improving the system's fault tolerance and long-term operational stability. The nested design of the movable rod 243 and the support plate 244, together with the slider 245, transforms the linear motion of the return spring 242 into precise lateral displacement adjustment. This ensures the real-time response of the adaptive component to changes in fiber layer thickness, and through the guiding effect of the slider 245 in the limiting groove 150, ensures that there is no radial offset during the adjustment process, maintaining the consistency of the working trajectory of the ceramic guide comb 280. The sliding fit between the connecting rod 241 and the adjusting channel 140, combined with the constraint of the slider 245 in the limiting groove 150, forms a dual guiding mechanism, which enables the adaptive adjusting component 240 to have horizontal stability during longitudinal extension and retraction, effectively suppressing the mechanism swaying phenomenon caused by fiber conveying vibration, and ensuring that the distance between the ceramic guide comb 280 and the conveyor belt 123 is constant.

[0022] Furthermore, the conveying assembly 120 includes a fixed seat 121 fixedly installed in the inner cavity of the support frame 110, a drive shaft 122 hinged to the outside of the fixed seat 121, a conveyor belt 123 movably sleeved on the outside of the drive shaft 122, and fish scale protrusions 124 fixedly installed on the outside of the conveyor belt 123.

[0023] The conveyor assembly 120 adopts an integrated design of fish scale protrusions 124 and conveyor belt 123. The intermittent support surface generated by the protrusions breaks the continuous contact between the steel fiber and the belt surface, fundamentally avoiding the risk of the hooks getting embedded in the mesh. The hinged structure of the drive shaft 122 and the fixed seat 121 allows the conveyor belt 123 to finely adjust the tension to adapt to the thermal expansion and contraction deformation requirements at different temperatures.

[0024] Preferably, the movable component 290 includes a damping damper 291 fixedly installed at the bottom of the telescopic rod 220, a connecting piece 292 fixedly installed at the bottom of the damping damper 291, and an adjusting vertical rod 293 hinged to the bottom of the connecting piece 292, the bottom of the adjusting vertical rod 293 being hinged to the limiting plate 270.

[0025] Among them, the active component 290 absorbs the instantaneous impact load of the telescopic rod 220 through the damping damper 291, and in conjunction with the hinge linkage between the adjusting vertical rod 293 and the limiting plate 270, the vertical vibration is converted into the slow swinging motion of the limiting plate 270, which avoids fiber splashing and prevents the ceramic guide comb 280 from excessively compressing and damaging the oxide layer on the fiber surface, thus achieving dynamic balance process control.

[0026] Furthermore, the support mechanism 100 also includes a top plate 160 fixedly installed on the top of the side plate 130, and a heater 170 fixedly installed on the top of the top plate 160.

[0027] The modular layout of the top plate 160 and the heater 170 forms a closed thermal circulation cavity. The heat insulation and reflection characteristics of the top plate 160 optimize the temperature field distribution, so that the heat radiation energy of the heater 170 is concentrated on the upper part of the fiber layer, which makes up for the uneven temperature defect on the inner side of the hook caused by traditional side heating and improves the uniformity of oxide film formation.

[0028] In use, the hook-shaped steel fibers are first conveyed by the conveyor belt 123 of the conveying component 120. The fish scale protrusions 124 effectively prevent the fibers from getting caught. During the conveying process, the ceramic guide comb 280 of the guide auxiliary mechanism 200 automatically adjusts its height under the linkage of the reset spring 242 and the slider 245 of the adaptive adjustment component 240 to achieve layered fiber guidance. At the same time, the damping damper 291 of the moving component 290 absorbs vibration and keeps the limit plate 270 stable. Under the heat radiation of the heater 170, the top plate 160 forms a uniform heating environment to complete the bluing process, and finally outputs rust-proof steel fibers with a uniform surface oxide film.

[0029] In summary, the support frame 110 and the conveying component 120 form a stable high-temperature conveying platform. The design of the fish-scale protrusions 124 effectively prevents fiber hooks from getting stuck. The adaptive adjustment component 240 achieves dynamic compensation through the linkage mechanism of the reset spring 242 and the slider 245, ensuring that the ceramic guide comb 280 always maintains the best contact pressure with the fiber layer. The shock absorption and hinge composite structure of the movable component 290 absorbs mechanical vibration and maintains the limiting accuracy. The closed thermal circulation system achieves uniform heating through the reflective characteristics of the top plate 160. The entire device solves the problems of fiber blockage and uneven oxidation in traditional processing processes through the organic combination of rigid support and flexible adjustment.
