Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment parts, in particular to a boron carbide ceramic wear-resistant wiper element. Background Art

[0002] The prior art discloses an adjustable height-jumping ceramic scraper for a papermaking machine, with an application publication number of CN106835802A and an application publication date of 20170613. The ceramic layer of the prior art is composed of ceramic blocks bonded side by side on high-strength fiberglass. The arrangement of the ceramic layer improves wear resistance. However, due to the gap at the joint of the ceramic blocks, water will flow into the gap when the scraper is wiping water, and may even be easily retained in the gap. Long-term use will cause the ceramic blocks to loosen, resulting in uneven joints between the ceramic blocks, thereby affecting the dehydration effect. Utility Model Content

[0003] The utility model aims to provide a boron carbide ceramic wear-resistant wiper element which can reduce water accumulation in gaps.

[0004] In order to achieve the above-mentioned purpose of the utility model, the boron carbide ceramic wear-resistant wiper element of the utility model adopts the following technical solutions:

[0005] A boron carbide ceramic wear-resistant wiper element comprises a plurality of wiper strips mounted on a base, each wiper strip comprising a support strip and a wear-resistant strip, the support strip being fixed to the base, the wear-resistant strip wrapping the outer circumference of the support strip, the wear-resistant strip having an interior provided with a mounting groove, the mounting groove being adapted for the support strip; the support strip extends along the length direction of the base, and the support strip is made of fiberglass; a plurality of wear-resistant strips are arranged along the length direction of the support strip, and the wear-resistant strips are made of boron carbide ceramic; the support strip comprises a support portion and a clamping portion, the clamping portion being arranged at the upper end of the support portion, the top of the clamping portion being provided with two symmetrical inclined surfaces, the butt ends of the two inclined surfaces being the inclined higher ends, the bottom of the clamping portion being provided with two symmetrically arranged clamping grooves, the two clamping grooves being respectively arranged on both sides of the support portion; the two side walls of the upper and middle sections of the support portion are vertical planes, the two side walls of the lower and middle sections of the support portion are inclined planes, the two inclined planes are symmetrically arranged, and the width of the bottom of the support portion is greater than the width of the upper end of the support portion.

[0006] Preferably, the ends of the wear-resistant strips are provided with grooves, the grooves of two adjacent wear-resistant strips correspond to each other, and mounting columns are inserted into the grooves, one end of the mounting column is inserted into the groove of one of the wear-resistant strips, and the other end of the mounting column is inserted into the groove of another adjacent wear-resistant strip.

[0007] Preferably, a magnet is provided at the bottom of the groove, and the mounting post is made of a magnetic material, with the end of the mounting post engaging with the magnet. The magnet allows the mounting post to be stably inserted into the groove, facilitating installation of the wear strip. Furthermore, the magnet secures the end of the mounting post, improving the stability of the butted installation of two adjacent wear strips.

[0008] Preferably, the cross section of the groove is set to be a quadrilateral.

[0009] Preferably, the upper end of the wear-resistant strip is configured as an inverted trapezoidal structure.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model provides an inclined surface at the top of the clamping portion. When there is a gap at the joint of two adjacent wear-resistant strips, the water scraped by the wiper element will slide along the inclined surface due to the presence of the inclined surface and will not be retained in the gap. Therefore, the looseness between the wear-resistant strip and the support strip is reduced, and the unevenness of the joint position of the wear-resistant strip is further avoided, thereby ensuring the dehydration effect. The structure is simple and practical.

[0012] 2. The utility model sets a groove at the end of the wear-resistant strip, and then inserts the installation column between the two adjacent wear-resistant strips. The installation column is used to position the two adjacent wear-resistant strips, ensuring that the wear-resistant strips are installed in the same plane, and further ensuring that the top of the wear-resistant strip is flush with the docking position.

After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0020] like Figure 1-5 As shown, a boron carbide ceramic wear-resistant wiper element includes a plurality of wiper strips mounted on a base 1, each wiper strip includes a support strip 2 and a wear-resistant strip 3, the support strip 2 is fixed on the base 1, the wear-resistant strip 3 wraps the outer periphery of the support strip 2, the upper end of the wear-resistant strip 3 is arranged as an inverted trapezoidal structure, the interior of the wear-resistant strip 3 is provided with a mounting groove 7, the mounting groove 7 is adapted to the support strip 2; the support strip 2 extends along the length direction of the base 1, and the support strip 2 is made of fiberglass; a plurality of wear-resistant strips 3 are arranged along the length direction of the support strip 2, and the wear-resistant strip 3 is made of boron carbide ceramic; the support strip 2 includes a supporting portion 2b and a clamping portion 2a, the clamping portion 2a is arranged at the upper end of the support portion 2b, and the top of the clamping portion 2a is provided with two symmetrical inclined surfaces 2d, and the butt end of the two inclined surfaces 2d is the inclined higher end The bottom of the clamping part 2a is provided with two symmetrically arranged clamping grooves 2c, and the two clamping grooves 2c are respectively arranged on both sides of the supporting part 2b; the two side walls of the upper section of the supporting part 2b are vertical planes, and the two side walls of the lower section of the supporting part 2b are inclined planes. The two inclined planes are symmetrically arranged, and the width of the bottom of the supporting part 2b is greater than the wide part of the upper end of the supporting part 2b; the end of the wear-resistant strip 3 is provided with a groove 4, and the cross-section of the groove 4 is set to a quadrilateral. The grooves 4 of two adjacent wear-resistant strips 3 correspond to each other, and the mounting column 5 is inserted into the groove 4, one end of the mounting column 5 is inserted into the groove 4 of one of the wear-resistant strips 3, and the other end of the mounting column 5 is inserted into the groove 4 of the other adjacent wear-resistant strip 3; a magnet 6 is provided at the bottom of the groove 4, and the mounting column 5 is made of magnetic material, and the end of the mounting column 5 is attracted to the magnet 6.

[0021] The specific working process and principle of the present invention are as follows: multiple wear-resistant strips 3 are docked and installed on the support strips 2, the support strips 2 provide high-strength support, and the wear-resistant strips 3 improve the wear-resistant effect; when the wiper element wipes the water, the scraped water will enter the gap at the docking point of the wear-resistant strips 3. At this time, since the inclined surface 2d is set on the top of the clamping part 2a, the water will slide along the inclined surface 2d and will not be retained in the gap, reducing the looseness between the wear-resistant strips 3 and the support strips 2. In addition, the mounting post 5 is inserted between two adjacent wear-resistant strips 3 for positioning. Combined with the action of the magnet 6, after the mounting post 5 is inserted into the groove 4, it is attracted and fixed by the magnet 6, so that the mounting post 5 will not easily slide out of the groove 4, thereby facilitating the installation of multiple wear-resistant strips 3. At the same time, it is ensured that the installation of the wear-resistant strips 3 is in the same plane, further ensuring that the docking position at the top of the wear-resistant strip 3 is flush, and ensuring the dehydration effect.
