Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of papermaking raw material processing equipment, specifically relating to an automatically cleanable papermaking raw material conveyor belt structure. Background Technology
[0002] Papermaking raw material conveyor belts are key equipment in papermaking production lines used for the continuous transport of raw materials such as wood pulp, waste paper, and straw. Their structure is usually composed of multiple layers of composite materials, including a wear-resistant rubber / polyurethane covering layer that carries the fiber raw materials, a polyester or steel wire rope core reinforcement layer that provides tensile strength, and a bottom anti-corrosion base fabric.
[0003] Currently, when papermaking raw material conveyor belts lack automatic cleaning functions, raw material debris continuously adheres to the conveyor belt surface and grooves, leading to cross-contamination, reduced conveying efficiency, and accelerated belt wear. Long-term accumulation of wet pulp can breed microorganisms that corrode the rubber layer, while fiber dust accumulated in dry environments increases the risk of fire. In extreme cases, residues can cause belt misalignment or idler blockage, requiring manual cleaning and disrupting production continuity. Utility Model Content

[0027] 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.
[0028] 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.
[0029] Example 1
[0030] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an automatically cleanable papermaking raw material conveyor belt structure, including:
[0031] The conveying mechanism 100 includes a support frame 110, a frame 120 fixedly installed on the top of the support frame 110, a drive motor 130 fixedly installed on the outside of the frame 120, and a conveyor belt 140 disposed in the inner cavity of the frame 120.
[0032] The cleaning mechanism 200 includes a support frame 210 fixedly installed on the top of the support frame 110, an adjustment channel 220 opened in the inner cavity of the support frame 210, a positioning component 230 disposed in the inner cavity of the adjustment channel 220, and a scraping component 240 disposed on the outside of the positioning component 230.
[0033] And, a dust-sweeping mechanism 300 used in conjunction with the cleaning mechanism 200.
[0034] The collaborative structure of the conveying mechanism 100, the cleaning mechanism 200, and the dust removal mechanism 300 achieves overall stability through the rigid connection between the frame 120 and the support frame 210. The spatial coordination between the conveyor belt 140 and the scraping component 240 forms a dynamic cleaning path. The drive motor 130 synchronously drives the conveying and cleaning actions, reducing the need for additional power sources. The design of the adjustable channel 220 allows the cleaning mechanism 200 to adapt to conveyor belts 140 of different widths, significantly improving the efficiency of residue cleaning during the papermaking raw material conveying process.
[0035] Specifically, the positioning component 230 includes a limiting plate 231 movably mounted on the top of the adjusting channel 220, a threaded sleeve 232 fixedly mounted on the top of the limiting plate 231, a fastening screw 233 threadedly mounted in the inner cavity of the threaded sleeve 232, a knob 234 fixedly mounted on the end of the fastening screw 233, and a slider 235 mounted on the bottom of the limiting plate 231. The slider 235 is elastically connected to the limiting plate 231. The slider 235 is movably mounted in the inner cavity of the adjusting channel 220. The end of the fastening screw 233 passes through the threaded sleeve 232 until it is threadedly connected to the inner cavity of the slider 235.
[0036] The positioning component 230 adopts a helical transmission structure of threaded sleeve 232 and fastening screw 233, combined with the elastic connection design of slider 235. When the knob 234 is rotated, the vertical pressure of scraper 244 can be finely adjusted. The elastic slider 235 absorbs the vibration of conveyor belt 140, avoids wear caused by rigid contact, and extends the service life of scraping component 240. The sliding pair structure of slider 235 and adjustment channel 220, combined with the end thread connection of fastening screw 233, achieves zero loosening after the scraper 244 is height positioned through the thread self-locking characteristic. At the same time, the guide rail constraint of slider 235 ensures no lateral deviation during scraping operation and maintains the straightness of the cleaning trajectory.
[0037] Furthermore, the cleaning mechanism 200 also includes a fixing plate 250 fixedly installed at the bottom of the slider 235, and a connecting rod 260 fixedly installed on the outside of the fixing plate 250.
[0038] The cantilever beam structure formed by the fixed plate 250 and the connecting rod 260 provides a rigid support base for the scraping component 240. The extended design of the connecting rod 260 increases the force arm of the scraper 244 and enhances the ability to peel off stubborn adhesive impurities.
[0039] Preferably, the scraping assembly 240 includes a vertical rod 241 fixedly installed on the outside of the connecting rod 260, a spring rod 242 fixedly installed on the bottom of the vertical rod 241, a positioning plate 243 fixedly installed on the bottom of the spring rod 242, and a scraper 244 fixedly installed on the bottom of the positioning plate 243.
[0040] The scraping assembly 240 consists of a spring rod 242 and a positioning plate 243 forming an elastic clamping structure. The spring rod 242 provides constant downward pressure to make the scraper 244 fit against the curved surface of the conveyor belt 140. The wide surface design of the positioning plate 243 disperses stress and avoids local excessive wear that may lead to missed scraping.
[0041] In use, after the drive motor 130 starts, it drives the conveyor belt 140 to transport papermaking raw materials. At the same time, the cleaning brush 350 rotates synchronously through the gear transmission of the drive component 320. During the conveying process, the spring rod 242 of the scraping component 240 causes the scraper 244 to continuously press against the surface of the conveyor belt 140 to remove residues. The pressure can be adjusted by the knob 234 of the positioning component 230. The cleaned debris is collected again by the rotating cleaning brush 350, and the elastic connection design of the slider 235 effectively absorbs vibration and maintains cleaning stability. Continuous cleaning and maintenance can be completed without manual intervention.
[0042] In summary, the conveying mechanism 100 and the cleaning mechanism 200 are rigidly connected by a frame 120 and a support frame 210 to ensure overall stability. The positioning component 230 set in the adjusting channel 220 achieves precise adjustment of the scraper 244 pressure through the helical transmission of the threaded sleeve 232 and the fastening screw 233. Combined with the elastic buffer design of the slider 235, it effectively absorbs the vibration of the conveyor belt 140. The cantilever structure formed by the fixed plate 250 and the connecting rod 260 enhances the scraping arm. The scraper 244 driven by the spring rod 242 maintains a constant contact pressure. Combined with the rotating cleaning brush 350 of the dust sweeping mechanism 300, a two-stage cleaning system is formed. The overall structure significantly reduces component wear while ensuring the cleaning effect, achieving efficient removal of residues on the surface of the conveyor belt 140 and long-term maintenance-free operation.
[0043] Example 2
[0044] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a dust-sweeping mechanism 300 for cleaning the area below the conveyor belt 140.
[0045] Specifically, the dust removal mechanism 300 includes a housing 310 fixedly installed on the outside of the support frame 110, a drive assembly 320 disposed in the inner cavity of the housing 310, a bearing seat 330 fixedly installed on the inner wall of the housing 310, a shaft 340 hinged to the outside of the bearing seat 330, and a cleaning brush 350 fixedly installed on the outside of the shaft 340.
[0046] Among them, the dust sweeping mechanism 300 has a rotating joint structure between the shaft 340 and the cleaning brush 350. Its beneficial effect is that the low-friction hinge of the bearing 330 allows the cleaning brush 350 to adaptively swing with the uneven surface of the conveyor belt 140, realizing the secondary collection of residual dust, and forming a graded cleaning system with the scraping component 240.
[0047] Furthermore, the drive assembly 320 includes a limiting seat 321 fixedly installed in the inner cavity of the housing 310, a drive gear 322 hinged to the outside of the limiting seat 321, a linkage gear 323 meshing with the drive gear 322, and a driven gear 324 meshing with the linkage gear 323. The outer side of the drive gear 322 is fixedly connected to the output end of the drive motor 130.
[0048] Among them, the drive component 320 has a gear meshing transmission chain structure. Its beneficial effects are: the driving gear 322 changes the transmission direction through the linkage gear 323, the driven gear 324 is directly connected to the shaft 340 to ensure speed matching, and the three-stage reduction design increases the torque of the sweeping brush 350, effectively removing impurities from crevices.
[0049] When in use, when the drive motor 130 starts, the power drives the conveyor belt 140 to run and the drive gear 322 to rotate through the output shaft. The driven gear 324 drives the shaft 340 to rotate at an optimized speed. The high-speed rotating cleaning brush 350, under the floating support of the shaft seat 330, automatically conforms to the bottom curved surface of the conveyor belt 140 for deep cleaning, and thoroughly removes the crevices and impurities that were not removed by the scraping component 240.
[0050] In summary, the drive assembly 320 adopts a structure in which the active gear 322 drives the driven gear 324 after being turned by the linkage gear 323. The output torque of the sweeping brush 350 is significantly improved through three-stage reduction. The low-friction hinge of the bearing seat 330 and the floating design of the shaft 340 enable the sweeping brush 350 to adapt to the curvature of the bottom of the conveyor belt 140, forming a three-dimensional cleaning system with the upper scraping assembly 240, effectively removing the dust accumulated at the bottom of the traditional conveyor belt.
