Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled material production, and particularly relates to an asphalt scraping device for waterproof coiled material production. Background Art
[0002] A waterproof coiled material is a flexible building material product that can be coiled into a roll shape, and is mainly used for building walls, roofs, tunnels, roads, landfills, etc. to resist the leakage of external rainwater and groundwater.
[0003] Generally, during the production process of waterproof coiled materials, asphalt needs to be applied to the base material (base fabric), and then the base material coated with asphalt passes between the upper conveying roller and the lower conveying roller and enters the film covering process.
[0004] However, since asphalt remains on the two conveying rollers when the base material passes between the upper conveying roller and the lower conveying roller after the asphalt is applied to the base material, if it is not cleaned regularly, it will cause the problem of uneven asphalt on the subsequent base material. Content of the Utility Model
[0005] The main purpose of the utility model is to provide an asphalt scraping device for waterproof coiled material production to solve the above-mentioned existing problems.
[0006] To achieve the above purpose, the utility model provides an asphalt scraping device for waterproof coiled material production, which includes an asphalt frame and a scraping structure;
[0007] A pressing roller is arranged in the middle of the asphalt frame, a rotating roller is arranged on the upper side of the front end of the asphalt frame, and an upper conveying roller and a lower conveying roller are respectively arranged on the upper side of the rear end of the asphalt frame;
[0008] The scraping structure is arranged at the rear side of the asphalt frame. The scraping structure includes a lateral moving member and a scraping member. There are two groups of the lateral moving members. Each group of the lateral moving members includes a lateral block, a moving plate and a driving member. The lateral block is connected to the end of the rear end of the asphalt frame. The moving plate is movably arranged in a lateral groove at the upper end of the lateral block. The driving member is used to drive the moving plate to move. The scraping member includes a rotating shaft, a long scraping knife and a short scraping knife. The rotating shaft is rotatably arranged between the two moving plates. The long scraping knife and the short scraping knife are respectively arranged on both sides of the rotating shaft.
[0009] The above beneficial effects are as follows: the base material passes between the rotating roller, the pressing roller, the upper conveying roller and the lower conveying roller in sequence. The upper conveying roller and the lower conveying roller are respectively driven by the motor to rotate, so that the base material coated with asphalt is conveyed to the next process. When cleaning the asphalt on the two conveying rollers, the rotating motor drives the rotating shaft to rotate 90°, so that the long scraper faces the upper conveying roller and the short scraper faces the lower conveying roller. Then, the driving member drives the moving plate to move in the transverse groove, and the moving plate drives the scraping member to move, so that the long scraper contacts the upper conveying roller, and at the same time the short scraper contacts the lower conveying roller. By the active rotation of the two conveying rollers, the long scraper and the short scraper respectively scrape off the residual asphalt on the two conveying rollers. After that, the moving plate drives the scraping member to move away from the two conveying rollers, and the rotating shaft rotates reversely by 90°, and the two scrapers face downwards. At this time, the base material can be conveyed to the next process again, so that the cleaning of the asphalt on the two conveying rollers can be completed simultaneously, which is very convenient.
[0010] A preferred solution is that a collection box is arranged below the scraping structure.
[0011] A preferred solution is that the rotating shaft is a hollow rotating shaft, and a plurality of leakage holes are arranged in the radial direction of the hollow rotating shaft.
[0012] A preferred solution is that heating elements are arranged inside both the long scraper and the short scraper.
[0013] A preferred solution is that the driving member is a lead screw, the lead screw is arranged in the transverse groove, and the lower end of the moving plate is arranged on the lead screw.
[0014] A preferred solution is that both ends of the upper conveying roller are respectively connected with lifting blocks, the lifting blocks are movably arranged in the vertical openings at the upper ends of the vertical blocks, and both ends of the lower conveying roller are respectively connected with the lower ends of the vertical blocks.

[0021] Combined with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described. Many specific details are set forth in the following description in order to fully understand 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 promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0022] As Figures 1 to 5 shown, the present invention provides an asphalt scraper device for waterproof coiled material production, including an asphalt frame 10 and a scraping structure 20;
[0023] A pressing roller 11 is arranged in the middle of the asphalt frame 10, a rotating roller 12 is arranged on the upper side of the front end of the asphalt frame 10, and an upper conveying roller 13 and a lower conveying roller 14 are respectively arranged on the upper side of the rear end of the asphalt frame 10;
[0024] The scraping structure 20 is arranged at the rear side of the asphalt frame 10. The scraping structure 20 includes a lateral moving member 210 and a scraping member 220. There are two groups of the lateral moving members 210. Each of the two groups of the lateral moving members 210 includes a lateral block 211, a moving plate 212 and a driving member 230. The lateral block 211 is connected to the end of the rear end of the asphalt frame 10. The moving plate 212 is movably arranged in a lateral groove 213 at the upper end of the lateral block 211. The driving member 230 is used to drive the moving plate 212 to move. The scraping member 220 includes a rotating shaft 221, a long scraper 222 and a short scraper 223. The rotating shaft 221 is rotatably arranged between the two moving plates 212. The long scraper 222 and the short scraper 223 are respectively arranged on both sides of the rotating shaft 221.
[0025] During the operation process, the substrate 1 passes successively between the rotating roller 12, the pressing roller 11, the upper conveying roller 13 and the lower conveying roller 14. The upper conveying roller 13 and the lower conveying roller 14 are respectively driven by the motor 51 to rotate, so as to convey the substrate 1 coated with asphalt to the next process. When cleaning the asphalt on the two conveying rollers, the rotating motor 61 drives the rotating shaft 221 to rotate 90°, so that the long scraper 222 faces the upper conveying roller 13 and the short scraper 223 faces the lower conveying roller 14. Subsequently, the driving member 230 drives the moving plate 212 to move in the transverse groove 213, and the moving plate 212 drives the scraping member 220 to move, so that the long scraper 222 contacts the upper conveying roller 13, and at the same time the short scraper 223 contacts the lower conveying roller 14. By the active rotation of the two conveying rollers, the long scraper 222 and the short scraper 223 respectively scrape off the residual asphalt on the two conveying rollers. After that, the moving plate 212 drives the scraping member 220 to move away from the two conveying rollers, and the rotating shaft rotates reversely by 90°, and the two scrapers face downwards. At this time, the substrate 1 can be conveyed to the next process again, so that the asphalt on the two conveying rollers can be cleaned simultaneously, which is very convenient.
[0026] Preferably, a collection box 71 is arranged below the scraping structure 20.
[0027] In order to prevent the asphalt from dripping everywhere when the substrate 1 coated with asphalt is conveyed to the next process, the dripping asphalt can be uniformly collected into the collection box 71.
[0028] Preferably, the rotating shaft 221 is a hollow rotating shaft 228, and a plurality of leakage holes 229 are arranged in the radial direction of the hollow rotating shaft 228.
[0029] When the two scrapers face downwards, the substrate 1 coated with asphalt will pass through the upper end of the hollow rotating shaft 228. At this time, the upper arc section 91 of the hollow rotating shaft 228 will support the substrate 1. When there is residual asphalt on the hollow rotating shaft 228, it will leak into the collection box 71 through the plurality of leakage holes 229.
[0030] In addition, when the long scraper 222 and the short scraper 223 respectively scrape the asphalt on the two conveying rollers, the scraped asphalt flows into the collection box 71 through the leakage holes 229 for unified collection.
[0031] In addition, by driving the scraping member 220 to move by the moving plate 212, the rotating shaft 221 can be moved to different positions, so that the supporting position of the substrate 1 can be adjusted, and thus the conveying position or angle of the substrate 1 can be adjusted, which helps to optimize the operation of the production line and the conveying efficiency of the coil.
[0032] Preferably, heating elements are arranged inside both the long scraper 222 and the short scraper 223.
[0033] When the asphalt remaining on the two conveying rollers hardens, at this time, a heating member is used to generate a certain temperature for the long scraper 222 and the short scraper 223, so that the hardened asphalt is softened, and the scraping of the asphalt on the conveying rollers can be quickly completed. The heating member is a prior art, such as a heating wire, a heating tube, etc., as long as a certain temperature can be generated for the two scrapers.
[0034] Preferably, the driving member 230 is a lead screw 231, the lead screw 231 is arranged in the transverse groove 213, and the lower end of the moving plate 212 is arranged on the lead screw 231.
[0035] The driving motor drives the lead screw 231 to rotate, so that the moving plate 212 moves along the transverse groove 213, and the moving plate 212 drives the scraping member 220 to move.
[0036] Preferably, both ends of the upper conveying roller 13 are respectively connected to the lifting blocks 105, the lifting blocks 105 are movably arranged in the vertical openings 107 at the upper ends of the vertical blocks 106, and both ends of the lower conveying roller 14 are respectively connected to the lower ends of the vertical blocks 106. The lifting cylinder 108 drives the lifting blocks 105 to move in the vertical openings 107, so as to adjust the height position of the upper conveying roller 13 according to the thickness of the asphalt dip-coated on the substrate 1 as required.
[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
