Description

TECHNICAL FIELD

[0001] The utility model relates to material processing technical field, concretely relates to a scraper felt structure. BACKGROUND

[0002] In the material processing industry, especially for the processing of flexible materials, after cutting with a disc cutter, the cutting edge of the material often produces some debris, burr and other defects, which not only affects the appearance quality of the product, but also may affect the subsequent processing procedures. The traditional processing method is usually to separately set a cleaning device on the cutting equipment, which increases the complexity and cost of the equipment, and the cleaning effect is limited, and it is difficult to achieve ideal processing effect. Therefore, an apparatus capable of being combined with the disc cutter cutting process to effectively process the material edge during cutting is urgently needed. SUMMARY

[0003] The utility model discloses a kind of scraper felt structures, which can clean scraper and ensure processing quality.

[0004] To achieve the above object, the present disclosure provides a scraper felt structure, which includes a scraper body, a felt mounting assembly and a felt. The felt mounting assembly includes a felt clamping serrated pipe and a serrated pipe tightening nut. The felt clamping serrated pipe is a tubular structure for clamping the felt. The outer surface of the felt clamping serrated pipe is provided with a serrated structure. The two ends of the felt clamping serrated pipe are provided with threads for connecting the serrated pipe tightening nut. The felt is positioned near the cutting path of the scraper body.

[0005] The felt mounting assembly of the basic scheme adopts the design of felt clamping serrated pipe and serrated pipe tightening nut. The serrated structure of the outer surface of the felt clamping serrated pipe increases the friction between the felt and the serrated pipe. When the serrated pipe tightening nut is tightened at both ends of the felt clamping serrated pipe, the serrated structure can prevent the felt from slipping or shifting during operation.

[0006] The serrated pipe tightening nut connected to both ends of the felt clamping serrated pipe can prevent the felt from shifting or falling off due to loose connection during cutting, further enhancing the tightness and stability of the connection, and improving the service life and reliability of the entire felt mounting assembly.

[0007] Since the felt is installed by the felt clamping serrated pipe and the serrated pipe tightening nut, when the felt needs to be replaced, only the serrated pipe tightening nut is unscrewed, and the old felt can be conveniently taken out and replaced with new felt. Compared with some complex integrated or adhesive installation methods, the replacement operation of the felt replacement of the technical scheme is more simple and fast, reduces the time and workload of equipment maintenance, and improves the use efficiency of the equipment. The felt position is set near the cutting path of the scraper main body, so that the felt can absorb debris and wipe the burr during the cutting process of the scraper.

[0008] As an implementable preferred solution, the scraper main body includes an upper disc cutter and a lower disc cutter, which are respectively connected with the driving device through respective cutter shafts and rotate in opposite directions through the driving of the driving device.

[0009] As an implementable preferred solution, the serrated pipe tightening nut adopts a hexagonal nut.

[0010] As an implementable preferred solution, the felt is made of wool or synthetic fiber material, and the width is greater than the width of the blade of the scraper main body.

[0011] As an implementable preferred solution, the thickness of the felt is between 5mm and 15mm.

[0012] As an implementable preferred solution, a gasket is further included, which is arranged at the other end of the serrated pipe tightening nut thread connection.

[0013] As an implementable preferred solution, the gasket is made of elastic material, and its shape matches the shape of the end of the serrated pipe tightening nut.

[0014] As an implementable preferred solution, the felt clamping serrated pipe adopts a metal material.

[0015] As an implementable preferred solution, the serrated structure is uniformly distributed on the outer surface of the felt clamping serrated pipe. BRIEF DESCRIPTION OF DRAWINGS

[0023] The present application will be further described in detail below in combination with the drawings:

[0024] Reference signs: upper disc cutter 1-1, lower disc cutter 1-2, felt mounting assembly 2, felt clamping serration pipe 2-1, serration pipe tightening nut 2-2, gasket 2-3, felt 3.

[0025] A scraper felt structure, comprising a scraper main body, a felt mounting assembly 2, and a felt 3.

[0026] Referring to Figure 1 The scraper main body comprises an upper disc cutter 1-1 and a lower disc cutter 1-2, which are cutting components of the present structure. The scraper main body is preferably made of high-strength and high-toughness alloy material, such as tungsten steel alloy or chromium molybdenum steel. The above-mentioned alloy material has good wear resistance and corrosion resistance, and can maintain stable scraping performance during long-term use.

[0027] The upper disc cutter 1-1 and the lower disc cutter 1-2 are connected with the driving device through respective cutter shafts. The driving device can be a motor, which drives the upper disc cutter 1-1 and the lower disc cutter 1-2 to rotate through belt transmission or gear transmission, and the rotation directions are opposite, so as to realize shearing cutting of the material.

[0028] The felt mounting assembly 2 is used for fixing and mounting the felt 3. Referring to Figure 2 The felt mounting assembly 2 comprises a felt clamping serrated pipe 2-1, a serrated pipe tightening nut 2-2 and a gasket 2-3.

[0029] The felt clamping serrated pipe 2-1 is preferably made of metal material and has a tubular structure for clamping the felt. The outer surface of the felt clamping serrated pipe 2-1 is provided with uniformly distributed serrated structures which can increase the friction with the felt 3, prevent the felt 3 from sliding during use, and will not damage the felt. The length of the felt clamping serrated pipe 2-1 is designed according to the length of the felt 3, and is generally slightly longer than the length of the felt 3, so as to completely wrap the two ends of the felt 3. The inner diameter of the felt clamping serrated pipe 2-1 is determined according to the actual installation requirement, and needs to ensure that the felt 3 can be smoothly inserted. The two ends of the serrated pipe 2-1 are provided with threads for connecting with the serrated pipe tightening nut 2-2.

[0030] The serrated pipe tightening nut 2-2 is connected with one end of the felt clamping serrated pipe 2-1 through threads. After the felt 3 is inserted into the felt clamping serrated pipe 2-1, the serrated pipe tightening nut 2-2 can be tightened to further extrude the felt 3, so that it is fixed more firmly in the felt clamping serrated pipe 2-1. The serrated pipe tightening nut 2-2 is preferably a hexagonal nut, which is convenient for operation by using a wrench or the like. The material of the serrated pipe tightening nut 2-2 is the same as that of the felt clamping serrated pipe 2-1, so as to ensure good cooperation performance and corrosion resistance.

[0031] The gasket 2-3 is arranged at the other end of the serrated pipe tightening nut 2-2 connected by threads. The gasket 2-3 is preferably made of elastic materials such as polyurethane or silica gel, and has good elasticity and wear resistance. The shape of the gasket 2-3 matches the shape of the end of the serrated pipe tightening nut 2-2. When the serrated pipe tightening nut 2-2 is tightened, the gasket 2-3 can play a buffering and sealing role. The gasket plays a buffering and sealing role, prevents external debris and other impurities from entering the threaded connection part, avoids the wear and corrosion of the impurities to the threads, maintains the integrity of the threads, and ensures that the tightening nut can work stably for a long time.

[0032] Referring to Figure 3 The felt 3 is a key material for processing the cutting edge. The felt 3 is made of wool or synthetic fiber material and has good softness and adsorption. The thickness of the felt 3 is selected according to the actual processing requirement, and is generally between 5mm and 15mm. The width of the felt 3 is slightly larger than the width of the cutting edge of the upper disc cutter 1-1 and the lower disc cutter 1-2, so as to ensure that it can completely cover the cutting edge of the material during cutting. The surface of the felt 3 is subjected to special carding and treatment, so that the fibers are more loose, thereby improving the ability of adsorbing debris and wiping the burr.

[0033] The installation process is as follows:

[0034] Place the felt 3 evenly in the zigzag pipe 2-1, and make sure it is wrinkle-free. Then, align one end of the zigzag pipe 2-1 with the rack or other fixed parts, and tighten the zigzag pipe nut 2-2 by screwing. During this process, the zigzag pipe nut 2-2 should be rotated gradually to ensure that the felt 3 is evenly and firmly clamped in the zigzag pipe 2-1. Finally, install a gasket 2-3 that matches the shape of the zigzag pipe nut 2-2 on the other end, and rotate the zigzag pipe nut 2-2 again until the desired clamping force is achieved.

[0035] Referring to Figure 4 Install the felt installation assembly 2 with the felt 3 installed through the connecting piece to the rack of the cutting equipment, adjust the position of the felt 3 to be near the cutting path of the upper disc cutter 1-1 and the lower disc cutter 1-2, and the surface of the felt 3 can be in good contact with the edge of the cut material.

[0036] The working process is as follows:

[0037] When the cutting equipment is started, the driving device drives the upper disc cutter 1-1 and the lower disc cutter 1-2 to rotate in opposite directions. The cutting material is fed into the cutting area between the upper disc cutter 1-1 and the lower disc cutter 1-2 under the action of the feeding device, and the upper disc cutter 1-1 and the lower disc cutter 1-2 cut the material. At the same time, the cutting edge produces debris and burrs, which will contact the felt 3 as the material moves. Because the felt 3 has good adsorption and softness, the debris will be adsorbed on the surface of the felt 3, and the burrs will be wiped flat by the felt 3. As the cutting process continues, the felt 3 will continuously process the cutting edge of the material, thereby improving the processing quality of the material.

[0038] During use, if the adsorption and wiping effect of the felt 3 is found to be reduced, the zigzag pipe nut 2-2 can be disassembled to remove the felt 3 for cleaning or replacement. When cleaning the felt 3, compressed air blowing, water washing, or light tapping can be used to remove debris and impurities on its surface. If the felt 3 is severely worn, a new felt 3 needs to be replaced to ensure the normal operation of the scraper felt structure. At the same time, if the gasket 2-3 is aged, deformed, or affects its buffering and sealing function, it should also be replaced in time.

[0039] The above is only an embodiment of the present application, and common knowledge such as specific structures and properties in the scheme is not described in detail, all ordinary technical knowledge in the technical field of the present application before the application date or the priority date is known to the person skilled in the art, all prior art in the field can be known, and the person skilled in the art has the ability to apply conventional experimental means before the date, and the person skilled in the art can perfect and implement the present scheme under the inspiration given in the present application, and some typical known structures or known methods should not be an obstacle for the person skilled in the art to implement the present application. It should be pointed out that, for the person skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
