A multifold doctor blade 100 according to an embodiment of the invention is described below with reference to fig. 1-4.

The multifold blade 100 according to an embodiment of the present invention, as shown in fig. 1 and 2, includes: a doctor body 1 and a spreader roll 2 for flattening building material. Be equipped with feed inlet 11 and feed inlet 12 down on the scraper body 1, feed inlet 11 is located the top of feed inlet 12 down, be formed with the first plane 13 and the second of pressing that are used for flattening building material on the scraper body 1 and press plane 14, first plane 13 that presses is located the top of feed inlet 12 down, plane 14 is pressed to the second is located the below of feed inlet 11, the reference surface is built out to scraper body 1, the reference surface is levelly and smoothly or tangent mutually with first plane 13 that presses, the reference surface is levelly and smoothly or tangent mutually with second plane 14 that presses. The nip roll 2 is rotatably connected to the doctor body 1, and the nip roll 2 is located below the first pressing plane 13 and above the second pressing plane 14. The multi-fold blade 100 is configured to be fed at least by the upper feed opening 11 when scraping from the bottom up and at least by the lower feed opening 12 when scraping from the top down.

In the description of the present invention, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. That is, in the present invention, "upper" indicates the a orientation, "lower" indicates the B orientation, a and B are opposite orientations, and the AB direction may be the up-down direction, the left-right direction, or the front-back direction, which is not limited in the present application. The upper feed opening 11 is located above the lower feed opening 12, which means that between the upper feed opening 11 and the lower feed opening 12, the upper feed opening 11 is located near the a position, and the lower feed opening 12 is located near the B position. The first flat pressing surface 13 is located above the lower feed opening 12, which means that between the first flat pressing surface 13 and the lower feed opening 12, the first flat pressing surface 13 is located adjacent to the a orientation, and the lower feed opening 12 is located adjacent to the B orientation. The second pressing plane 14 is located below the upper feed opening 11, which means that between the second pressing plane 14 and the upper feed opening 11, the upper feed opening 11 is located adjacent to the a orientation, and the second pressing plane 14 is located adjacent to the B orientation. In addition, the multi-fold blade 100 scrapes from the bottom to the top, which means that the blade scrapes from the B direction to the a direction as shown in fig. 3; the multi-fold blade 100 is directed to scraping from the a-orientation to the B-orientation as shown in fig. 4. All the descriptions mentioned above and below can be interpreted in the above manner. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

It can be understood that, in the prior art, if the building surface is loaded, the building material is firstly piled on the building surface by the scraper, then the piled building material is flattened and evenly pressed by the scraper, then the flattened building material is scraped by the scraper, and the building material on the same area can be scraped by scraping the scraper for multiple times. In the applied scheme, the multi-fold scraper 100 can be used for scraping the building materials through the scraper body 1 and the flattening roller 2 by feeding (such as putty and the like) through at least one of the upper feeding hole 11 and the lower feeding hole 12, so that the processes of feeding while feeding are reduced before scraping.

And when nip roll 2 rotated for scraper body 1, can the roll extrusion wait to scrape building material to can flatten and wait to scrape building material. The first 13 and second 14 press planes can act on the building material to be scraped to further press and smooth the building material to be scraped. That is to say, in the operation of the multi-fold scraper 100, the processes of feeding, rolling and scraping can be performed simultaneously, thereby greatly saving the construction time and reducing the labor intensity of workers.

As shown in fig. 3, when the multi-fold scraper 100 scrapes from bottom to top, the multi-fold scraper can be fed from the upper feeding port 11, at this time, the flattening roller 2 rotates relative to the scraper body 1 to flatten the building material to be scraped, and at least the second flattening surface 14 can further compress and flatten the building material to be scraped. When the multi-fold scraper 100 scrapes from bottom to top, the lower feed inlet 12 may be selected to be not fed or to be fed less.

As shown in fig. 4, when the multi-fold scraper 100 scrapes from top to bottom, the building material can be fed from the lower feeding hole 12, and at this time, the flattening roller 2 rotates relative to the scraper body 1 to flatten the building material to be scraped, and at least the first flattening surface 13 can further compress and flatten the building material to be scraped. When the multi-fold scraper 100 scrapes from top to bottom, the upper feeding port 11 may be selected to be not fed or to be fed less.

Thus, the multi-fold scraper 100 can act on the building material to be scraped from top to bottom and also can act on the building material to be scraped from bottom to top without switching the direction or returning to the initial position for operation, which can further shorten the construction time.

In the scheme, if the flattening roller and the flattening surface are sequentially arranged on one side of the feeding hole, when the multi-fold scraper scrapes upwards from the initial position and reaches the upper boundary of the surface to be scraped, the direction needs to be switched (for example, the multi-fold scraper rotates by 180 degrees) or the multi-fold scraper returns to the horizontal plane where the initial position is located, so that the operation can be carried out, and the operation efficiency is low.

The multi-fold scraper 100 of the embodiment of the invention is configured to be at least fed by the upper feeding port 11 when the multi-fold scraper 100 scrapes from bottom to top, the flattening roller 2 and at least the second pressing plane 14 can act on the building material to be scraped, and at least the lower feeding port 12 feeds when the multi-fold scraper 100 scrapes from top to bottom, and the flattening roller 2 and at least the first pressing plane 13 can act on the building material to be scraped, so that when the multi-fold scraper 100 moves to the boundary of the surface to be scraped, the direction does not need to be switched, or the multi-fold scraper returns to the initial position, and continuous operation can be realized by directly changing the moving direction of the multi-fold. Thus, when the multi-fold blade 100 is adapted to a robot hand such as a screed robot, the movement of the robot hand can be simplified, energy can be saved, and work efficiency can be improved. When manual operation is adopted, the operation steps of workers can be simplified, the labor intensity of the workers is reduced, and the operation efficiency is improved.

According to the multi-fold scraper 100 provided by the embodiment of the invention, the processes of feeding, rolling and scraping can be simultaneously carried out, so that the construction time is greatly saved, and the labor intensity of workers is reduced. By configuring the multifold blade 100 to be fed at least by the upper feed opening 11 when scraping from bottom to top, the spreader roll 2, at least the second nip surface 14, can act on the building material to be scraped. At least the lower feed opening 12 feeds the building material to be scraped while the building material is being scraped from above downwards, and the spreader roll 2, at least the first nip surface 13, can act on the building material to be scraped. Therefore, the operation efficiency of the multi-fold blade 100 can be improved, for example, when the multi-fold blade 100 moves to the boundary of the surface to be scraped, the direction does not need to be switched, the operation does not need to return to the initial position, and the continuous operation can be performed only by changing the movement direction.

In some embodiments, as shown in fig. 1 and 2, the first pressing plane 13 is located above the upper feed opening 11, and the second pressing plane 14 is located below the lower feed opening 12. Like this as shown in fig. 3, when the multi-fold scraper 100 scrapes from bottom to top, the multi-fold scraper can be fed through the upper feed opening 11, or can be fed through the upper feed opening 11 and the lower feed opening 12 together, at this time, the flattening roller 2 rotates relative to the scraper body 1 to flatten the building material to be scraped, and the second flattening surface 14 can further compress and flatten the building material to be scraped. As shown in fig. 4, when the multi-fold scraper 100 scrapes from top to bottom, the multi-fold scraper may be fed through the lower feeding port 12, or through the upper feeding port 11 and the lower feeding port 12, at this time, the flattening roller 2 rotates relative to the scraper body 1 to flatten the building material to be scraped, and the first flattening surface 13 may further compress and flatten the building material to be scraped. That is to say, when the multi-fold scraper 100 is scraped from bottom to top, the nip roll 2 and the second nip plane 14 can act on and wait to scrape building material, and when the multi-fold scraper 100 is scraped from top to bottom, the nip roll 2 and the first nip plane 13 can act on and wait to scrape building material, are favorable to improving and wait to scrape the homogeneity of building material atress, improve the operation quality of multi-fold scraper 100.

Specifically, as shown in fig. 2 and 3, the blade body 1 is formed with a first receiving surface 131 and a first feeding surface 132 between the first nip surface 13 and the nip roller 2, the first feeding surface 132 is connected below the first receiving surface 131, and the first receiving surface 131 and the first feeding surface 132 extend in a direction away from the reference surface in a direction toward each other, and the upper feed port 11 is located on the first receiving surface 131. It will be appreciated that the first receiving surface 131 defines the upper feeding opening 11, so that the first receiving surface 131 can improve the stability of the feeding of the upper feeding opening 11, and the first receiving surface 131 can collect the construction material scraped by the lower edge of the first pressing plane 13 when the construction material is scraped from the top to the bottom. After the upper feeding opening 11 is fed, the first feeding surface 132 may be used for carrying the building material to be scraped, and may allow the building material to be scraped to adhere to the surface to be scraped. The first collecting surface 131 and the first feeding surface 132 extend in a direction away from the reference surface in a direction toward each other, so that the working area of the first collecting surface 131 and the first feeding surface 132 can be increased, and the working efficiency of the multi-fold blade 100 can be improved.

As shown in fig. 2 and 4, the doctor body 1 is formed with a second receiving surface 141 and a second feeding surface 142 between the second nip surface 14 and the nip roller 2, the second feeding surface 142 is connected above the second receiving surface 141, and the second receiving surface 141 and the second feeding surface 142 extend in a direction away from the reference surface in a direction toward each other, and the lower feed opening 12 is located on the second receiving surface 141. It will be appreciated that the second receiving surface 141 defines the lower feed opening 12, so that the second receiving surface 141 can improve the stability of the feeding of the lower feed opening 12, and the second receiving surface 141 can collect the construction material scraped by the upper edge of the second pressing plane 14 when the construction material is scraped from the bottom to the top. After the lower feeding hole 12 feeds, the second feeding surface 142 can be used for limiting the building materials to be scraped, so that the building materials to be scraped are attached to the surface to be scraped. The second collecting surface 141 and the second feeding surface 142 extend in a direction away from the reference surface in a direction toward each other, so that the working area of the second collecting surface 141 and the second feeding surface 142 can be increased, and the working efficiency of the multi-fold blade 100 can be improved.

Further, as shown in fig. 2, the first receiving surface 131 and the first feeding surface 132 are inclined planes having an included angle with respect to the reference surface. It can be understood that when the multi-fold scraper 100 acts on the surface to be scraped, the first material receiving surface 131 and the first material loading surface 132 form an included angle with the surface to be scraped, and the first pressing plane 13 has a large scraping force on the building material to be scraped. The reaction force and the friction force of the surface to be scraped to the building material to be scraped are large, so that the operation quality of the multifold scraper 100 can be improved, and the multifunctional scraper has high troweling quality and good putty scraping effect. In addition, the inclined plane is also favorable for the building material to be scraped to flow towards the surface to be scraped, so that the adhesion effect of the building material to be scraped can be improved.

Optionally, as shown in fig. 2, the included angles of the first material receiving surface 131 and the first material loading surface 132 with respect to the reference surface are in the range of 19 ° to 29 °, so that the included angles of the first material receiving surface 131 and the first material loading surface 132 with the surface to be scraped are small, and the force of the first pressing plane 13 on the building material to be scraped, such as putty, is large, which is beneficial to improving the operation quality of the multifold scraper 100.

Alternatively, as shown in fig. 2, the first material receiving surface 131 and the first material loading surface 132 are respectively arranged at an angle of 24 ° relative to the reference surface, and the reaction force and the friction force of the surface to be scraped to the building material to be scraped such as putty reach the maximum value, so that the working effect of the multi-fold blade 100 can be further improved.

As shown in fig. 2, the second receiving surface 141 and the second feeding surface 142 are inclined planes having an included angle with respect to the reference plane. It can be understood that when the multi-fold scraper 100 acts on the surface to be scraped, the second material receiving surface 141 and the second material loading surface 142 form an included angle with the surface to be scraped, and the scraping force of the building material to be scraped by the second pressing plane 14 is large. The reaction force and the friction force of the surface to be scraped to the building material to be scraped are large, so that the operation quality of the multifold scraper 100 can be improved, and the multifunctional scraper has high troweling quality and good putty scraping effect. In addition, the inclined plane is also favorable for the building material to be scraped to flow towards the surface to be scraped, so that the adhesion effect of the building material to be scraped can be improved.

Optionally, as shown in fig. 2, the included angles of the second material receiving surface 141 and the second material loading surface 142 with respect to the reference surface are in the range of 19 ° to 29 °, so that the included angles of the second material receiving surface 141 and the second material loading surface 142 with the surface to be scraped are small, and the scraping force of the second pressing plane 14 on the building material to be scraped, such as putty, is large, which is beneficial to improving the operation quality of the multifold scraper 100.

Alternatively, as shown in fig. 2, the second material receiving surface 141 and the second material loading surface 142 respectively have an included angle of 24 ° with respect to the reference surface, and the reaction force and the friction force of the surface to be scraped to the building material to be scraped, such as putty, reach the maximum value, so that the working effect of the multi-fold scraper 100 can be further improved.

In some alternative embodiments, as shown in fig. 2, the doctor body 1 is formed with a first blanking surface 133 and a second blanking surface 143, the first blanking surface 133 is located between the upper feed opening 11 and the nip roll 2, and the second blanking surface 143 is located between the nip roll 2 and the lower feed opening 12. Thus, when the multi-fold doctor blade 100 is in operation, the first blanking surface 133 and the second blanking surface 143 can be pressed onto the building surface from the feeding at the upper feeding port 11 and the lower feeding port 12, respectively, so that the flattening roller 2 can be rolled on the building material which has been fed after the pressing. The operation efficiency and the operation quality of the multi-fold scraper 100 can be improved, and the operation times of the multi-fold scraper 100 on the surface to be scraped can be reduced, for example, the multi-fold scraper 100 can perform a single operation to achieve a good operation effect. And some multi-fold scrapers need to scrape the same area for multiple times to meet the process requirements, and the efficiency is low.

In particular, the first and second blanking surfaces 133 and 143 are level and arranged tangentially to the spreader bar 2. It is understood that when the multi-fold blade 100 scrapes from bottom to top, the first blanking surface 133 may act on the building material to be scraped, preliminarily flatten the building material to be scraped, and then the flattening roller 2 may further flatten the building material to be scraped, and the second blanking surface 143 may play a role of assisting in flattening. When multi-fold scraper 100 from top to bottom scrapes, second charge level 143 can act on and wait to scrape building material, tentatively flattens and waits to scrape building material, and nip roll 2 can further flatten later and wait to scrape building material, and first charge level 133 can play supplementary effect of leveling of receiving to improve the effect of flattening, make multi-fold scraper 100 only need the single operation just can satisfy higher technological requirement. That is, the arrangement of the first blanking surface 133 and the second blanking surface 143 can improve the area and effect of a single operation of the multi-fold blade 100, thereby achieving double improvement of efficiency and quality. The height of the multi-fold scraper is changed to increase the operation area in the prior art, but multiple scraping operations are needed to meet the process requirements.

In some alternative embodiments, the doctor body 1 is formed with a first stock level 134 and a second stock level 144, the first stock level 134 is connected below the first stock level 133, the second stock level 144 is connected above the second stock level 143, the first stock level 134 and the second stock level 144 extend away from the reference plane in a direction towards each other, and the spreader roll 2 is located between the first stock level 134 and the second stock level 144. It can be understood that the space between the first material storage surface 134 and the second material storage surface 144 and the flattening roller 2 can be used for temporarily storing the building materials, for example, when the flattening roller 2 rotates to roll the building materials, the excess building materials can be rolled out, and at this time, the building materials to be scraped can be temporarily stored at the first material storage surface 134 and the second material storage surface 144, so that the excess materials are prevented from being excessively adhered to the flattening roller 2 to affect the rolling effect. In addition, when there is an uneven portion, the building materials to be scraped temporarily stored on the first material storage surface 134 and the second material storage surface 144 can be filled, so that the working effect of the multi-fold scraper 100 is improved.

Specifically, the first material storage surface 134 and the second material storage surface 144 are inclined planes having an included angle with respect to the reference plane. It can be understood that, when the multi-fold scraper 100 acts on the surface to be scraped, the first material storage surface 134 and the second material storage surface 144 form an included angle with the surface to be scraped, so that the first material storage surface 133 and the second material storage surface 143 have a large scraping force on the building material to be scraped, thereby improving the operation quality of the multi-fold scraper 100, such as high troweling quality and good putty scraping effect. In addition, the inclined plane is also beneficial to the building materials to be scraped to flow towards the surface to be scraped, so that the filling effect of the building materials to be scraped on the first material storage surface 134 and the second material storage surface 144 is improved.

Optionally, the first material storage surface 134 and the second material storage surface 144 respectively have an included angle in a range of 19 ° to 29 ° with respect to the reference surface, so that the included angle between the first material storage surface 134 and the second material storage surface 144 and the surface to be scraped is small, which can make the scraping force of the first blanking surface 133 and the second blanking surface 143 on the putty large, and is beneficial to improving the operation quality of the multi-fold scraper 100.

Optionally, the first material storage surface 134 and the second material storage surface 144 are respectively arranged at an angle of 24 ° relative to the reference surface, and the reaction force and the friction force of the surface to be scraped to the building material to be scraped, such as putty, reach the maximum value, so that the working effect of the multi-fold scraper 100 can be further improved.

Optionally, the doctor body 1 further comprises side plates 15, the side plates 15 being located on both sides of the first and second

pressing planes
