Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The flitch of scraping now has the mode to set up sunken draw-in groove on cuboid billet one side, sets up polyurethane wear-resisting strip into the T font, and the outstanding one side of T font is cast in the draw-in groove. The adhesive tape in the mode is easy to separate from the steel strip, the replacement of the adhesive tape is troublesome after the adhesive tape falls off, and the raw materials cannot be reused; the rubber surface of the mold is damaged, the cloth is seriously uneven, the pressed product is degraded into waste, the mold is damaged, and the empty kiln can be caused, such as greater loss caused by product color difference, less yield and the like, so that the economic benefit of an enterprise is influenced.

The utility model discloses then two following technical problem have been solved: firstly, the wear-resisting adhesive tape of the existing scraping plate is easy to fall off from a steel plate, and the abrasion-resisting adhesive tape cannot be repaired and reused after falling off, so that resources are wasted. Secondly, the friction resistance between the abrasion-resistant rubber strips on the existing scraping plates and the frame surface of the die assembly is large, the abrasion is easy, the jumping is easy to generate in the operation process, the cloth is uneven, and the defects of layering, large head and small head, large thickness difference deviation and the like are caused.

Referring to fig. 1 and fig. 2, the present invention provides a scraping plate, including: the scraping plate comprises a scraping plate body 100 and rubber strips 200 arranged on the lower end face of the scraping plate body 100; the adhesive tape 200 comprises a fixing part 210 and an adhesive tape body 220 formed on the fixing part 210 in a glue casting manner; the scraper plate body 100 is fixedly connected to the fixing portion 210. Like this, will scrape the flitch and divide into two parts, adopt fixed connection's mode to connect, compare in prior art's card and hold in the recess, the connected mode is more firm, adhesive tape 200 and scrape between the flitch body 100 and be difficult for droing. And, set up fixed part 210 in adhesive tape 200, pass through the integrative setting of casting glue mode with fixed part 210 and adhesive tape body 220, strengthened the steadiness for adhesive tape body 220 is difficult for droing with fixed part 210. Like this for adhesive tape 200 is difficult for droing with scraping flitch body 100, has improved production efficiency.

In one implementation, the scraper plate body 100 and the fixing portion 210 are both provided as steel bars. The steel bar has high hardness and is easy to be fixedly connected, such as screw connection. Specifically, the scraper body 100 is configured as a first steel bar, and the fixing portion 210 is configured as a second steel bar. Like this, first billet and second billet fixed connection, the structure is firm, and both are difficult to break away from, are favorable to scraping the holistic stability of flitch.

In one implementation, the fixing portion 210 is configured as a rectangle, and the fixing portion 210 includes a first side, a second side, a third side, and a fourth side, where the first side and the third side are opposite to each other, and the second side and the fourth side are opposite to each other; the adhesive tape body 220 is made of polyurethane adhesive formed on the first side, the second side, and the third side of the fixing portion 210 by a glue casting method. That is, the strip 200 is a polyurethane wear strip, and the polyurethane adhesive has high tensile strength, excellent elasticity, wear resistance, oil resistance, and cold resistance.

In a further implementation manner, referring to fig. 3, an end surface of the rubber strip body 220 facing away from the scraper plate body 100 includes: a first inclined plane 110, a parallel plane 120 and a second inclined plane 130 connected in sequence; the first inclined surface 110 and the second inclined surface 130 are arranged in a V shape, and the opening directions of the first inclined surface 110 and the second inclined surface 130 face the scraper plate body 100. That is to say, the longitudinal section of adhesive tape body 220 roughly is the V style of calligraphy, and installs in adhesive tape body 220 terminal surface down, and polyurethane glue both wear-resisting, also can not drop, warp for cloth stable quality. Therefore, the adhesive tape 200 on the lower end surface of the scraping plate can uniformly scrape the powder filled in the die cavity, and the pressing forming quality after the distribution is finished is facilitated. And the casting glue is of a V-shaped structure, the contact area of the casting glue with the bottom plate of the skip car and the surface of the middle frame of the assembly is small, the jumping generated in the operation process is avoided, and the cloth quality is improved.

In a further implementation manner, the lower end surface of the scraper plate body 100 is disposed to fit with the fourth side surface of the fixing portion 210. That is to say, scrape flitch body 100 with the position that the laminating of fixed part 210 set up does not have the casting polyurethane to glue, but directly will scrape flitch body 100 and fixed part 210 fixed connection, has strengthened the steadiness of structure for adhesive tape 200 is difficult to drop from scraping flitch body 100.

In one implementation, referring to fig. 4, the scraper further includes: a screw 300; the scraper plate body 100 and the fixing portion 210 are fixedly connected by the screw 300. Utilize screw 300 fixed connection, when needing to change adhesive tape 200, directly lift off screw 300, it is very convenient, scrape flitch body 100 then can cyclic utilization.

In a further implementation manner, please refer to fig. 4, the scraper body 100 is a rectangular parallelepiped, the scraper body 100 is provided with a plurality of first screw holes 140 along the length direction, and the first screw holes 140 are disposed through the scraper body 100. Since the scraping plate body 100 is in a rectangular shape, the plurality of first screw holes 140 are formed in the scraping plate body 100 along the length direction, the number of the first screw holes 140 is increased, and the connection stability between the scraping plate body 100 and the fixing portion 210 is further improved.

In a further implementation manner, referring to fig. 5, the fixing portion 210 is a cuboid, that is, a longitudinal section of the fixing portion 210 is a rectangle, the fixing portion 210 is provided with a plurality of second screw holes 211 along a length direction, and the second screw holes 211 are disposed corresponding to the first screw holes 140.

In a further implementation, referring to fig. 6, 7 and 8, the screws are received in the first screw holes 140 and the second screw holes 211.

In a further implementation, the screw is a socket head cap screw. The mode of hexagon socket head cap screwed connection makes to be connected firmly, does not have the condition that adhesive tape 200 and scraping plate body 100 drop, greatly reduced the replacement rate of scraping the flitch.

That is, a plurality of holes for mounting the hexagon socket head cap screws are punched on the rectangular scraper plate body 100; the end face of the rubber strip body 220 (i.e. polyurethane rubber) is an irregular hexagon combined by a rectangle and a trapezoid, a corresponding mold can be arranged, and the structure is formed by casting in the mold.
