Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of new finished wall processing equipment, and specifically relates to a cement-based foam surface removal device and a cement-based foam surface automatic removal line, and in particular to a cutting device for removing an ultra-lightweight, fast-curing cement-based foam surface for thermal insulation and heat insulation filling of a new finished wall. Background Art
[0002] Green rural prefabricated buildings use structural and functional integrated wall materials based on cold-bent thin-walled frames. The filling material in the keel can be selected from ultra-lightweight, fast-curing cement-based foam. Compared with traditional materials such as polyurethane, rock wool, glass wool, microporous calcium silicate, foamed cement, aerogel composite felt, and aeroconcrete, it has outstanding characteristics such as light weight, thermal insulation, fire resistance, hydrophobicity, and low cost. It is currently a hot material for new green rural prefabricated buildings.
[0003] The cement-based foam filling in the keel wall is prepared by chemical foaming technology. Due to its process characteristics, a raised surface foam layer will be formed on the surface above the keel frame, which needs to be cut off after curing to cover the upper cover plate. Unlike traditional foamed cement boards, the cement-based foam surface has a double-layer structure: (1) a surface hard shell with a thickness of about 5-30mm, high hardness, and a compressive strength of about 0.5-1.0MPa; (2) an internal foam body structure with a low hardness, a compressive strength of about 0.08-0.2MPa, and a high moisture content. The moisture content in the solid pore wall is generally greater than 40%. The above material and structural characteristics make it impossible to cut the surface foam layer using traditional tools such as knives and wire saws. It is urgent to develop new cutting equipment that adapts to its unique material composition and structure and meets the requirements of continuous and rapid production. Utility Model Content

[0008] As an embodiment of the utility model, the left straight rod is provided with a first connector fixing groove for adjusting the relative position of the handle bolt and the left straight rod; the right straight rod is provided with a second connector fixing groove for adjusting the relative position of the handle bolt and the right straight rod, and the second connector fixing groove corresponds to the position of the first connector fixing groove.
[0009] As an implementation manner of the present utility model, the left straight rod has the same structure as the right straight rod, and the length of the first connector fixing groove or the second connector fixing groove is not less than 500 mm.
[0010] As an implementation mode of the present utility model, the angle between the front edge of the cutting tool and the horizontal plane is 30-35 degrees; and / or the width of the cutting tool is 10-20 mm.
[0011] As an embodiment of the utility model, the front edge of the cutting tool and / or the side of the cutting tool in contact with the cement-based foam is coated with a polytetrafluoroethylene coating, and the thickness of the polytetrafluoroethylene coating is 20-50 μm.

[0013] As an implementation mode of the utility model, the support beam includes an upper support beam and a lower support beam, and the distance between the upper support beam and the lower support beam is not less than 1 / 4 of the height of the left straight rod or the right straight rod.
[0014] The second aspect of the utility model provides an automatic cement-based foam surface removal line, comprising a conveyor belt and the cement-based foam surface removal device described in the first aspect, the cement-based foam surface removal device also comprising a fixed chassis, the fixed chassis comprising a left fixed chassis and a right fixed chassis corresponding to the left straight rod and the right straight rod respectively, the left fixed chassis and the right fixed chassis having the same structure; the connection position between the left fixed chassis and the left straight rod is at the center of the left fixed chassis, and the connection position between the left fixed chassis and the set plane is arranged on the diagonal line of the left fixed chassis; and / or, the set plane is the ground or tooling equipment; the conveyor belt is arranged between the left straight rod and the right straight rod; a plurality of wall keels filled with cement-based foam are relatively fixed on the conveyor belt, which is used to drive the wall keels to the cement-based foam surface removal device to complete the removal of excess cement-based foam on the surface of the wall keel.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] (1) The cutting tool integrates the characteristics of high hardness, high sharpness, and ultra-thinness. It is made of high-hardness tungsten steel with a hardness of up to HRC69 to 81, which is significantly higher than traditional carbon steel, stainless steel, manganese steel and other materials (~HRC40-60). It has good wear resistance when cutting cement-based foam hard surface and has a longer service life; the cutting tool has a cutting edge angle of 30-35 degrees, which has good sharpness and can avoid blade wear or damage caused by too small a cutting edge angle; the thickness of the cutting tool is set to 1.0±0.2mm and the width is 5-50mm, which not only ensures the strength and sharpness of the tool, but also effectively avoids a large amount of cutting debris caused by a thick blade;
[0017] (2) The cutting edge and bottom of the cutting tool are coated with polytetrafluoroethylene. The polytetrafluoroethylene coating at the cutting edge can significantly reduce the cutting resistance between the cutting edge and the cement-based foam, making the cutting smoother. In addition, the polytetrafluoroethylene coating at the cutting edge and bottom gives the tool a strong water-repellent property, which can effectively prevent high-water content cutting debris from adhering to the cutting edge and bottom of the blade, thereby avoiding the formation of "furrows" during the cutting process, and thus obtaining high-quality products. When using conventional cutting tools, due to the hydrophilicity of the metal tool material itself, "furrows" will inevitably form, causing tool movement obstruction and product surface quality problems;
[0018] (3) The utility model adopts a method in which the cutting tool is fixed and the cement-based foam to be cut moves forward in a straight line to perform surface cutting operations. This is simpler and more efficient than the traditional method in which the product to be cut is fixed and the tool moves, and has higher production efficiency. It is particularly suitable for continuous product cutting operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words such as "up", "down", "left", "right", "front" and "back" used generally refer to the up, down, left and right of the device in actual use or working state, specifically the drawing direction in the drawings. In the utility model, the X direction, the Y direction, and the Z direction are represented by Figure 1 For example, the following definition is made: The X direction is Figure 1 The left and right directions in the figure are the length direction of the cutting tool 1; the Y direction is Figure 1 The direction of penetrating the paper surface in the figure is the width direction of the cutting tool 1; the Z direction is Figure 1 The up-down direction in the figure is also the thickness direction of the cutting tool 1.
[0032] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present utility model. In addition, in the following embodiments, the description of each embodiment has its own emphasis. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.
[0033] See also Figures 1 to 8The utility model provides a cement-based foam surface removal device, which is particularly suitable for removing the cement-based foam surface layer of a new finished wall filling. It includes a cutting tool 1, a connector 2, a bracket 3 and a fixed chassis 4. The bracket 3 is fixedly arranged on the fixed chassis 4, and the fixed chassis 4 is used to be fixed on a set plane. The set plane can be the ground or a tooling equipment, such as an assembly line equipment. The bracket 3 is a square frame, and at least two connectors 2 are respectively arranged on both sides of the bracket 3. The connector 2 includes a first edge 210 and a second edge 220 that are fixedly arranged. The first edge 210 is used to fit and fix with the bracket 3, and the second edge 220 is used to fit partially with the cutting tool 1. Figure 1 In this specific embodiment, the connector 2 is substantially in an "L"-shaped structure, the first side 210 is a long side arranged in the up-down direction, and the second side 220 is a short side arranged in the left-right direction.
[0034] When it is necessary to cut the cement-based foam surface layer on the keel wall module, the light steel keel wall module that has been cured is transported to the cutting device described in the utility model. For example, the light steel keel wall module can be placed on a turnover vehicle and the light steel keel wall module can be moved by rail. Then, the height of the cutter is adjusted according to the height of the wall module and the height of the raised layer of the cement-based foam surface layer to meet the cutting requirements. The height adjustment method will be described in detail later. Then, the wall module is moved from front to back (specifically to the Figure 1 The surface is cut by pushing the tool through the plane (in the middle is the direction of penetration), and then the cut surface is collected by a specific tooling to enter the subsequent processes such as the cover plate.
[0035] It can be understood that the focus of this solution is to cut cement-based foam flatly, thereby removing the excess position on the surface of cement-based foam. The existing cement-based cutting device focuses on longitudinal cutting of cement-based foam, that is, cutting cement-based materials into multiple sections of cement-based foam. For flat cutting, the focus needs to be considered in the smoothness of the cutting process, and how to avoid the reduction of product quality due to the adhesion of cutting debris on the blade and the bottom of the tool during the process of cutting the excess cement-based foam on the surface of the wall keel.
[0036] See also Figure 1-3 The cutting edge of the cutting tool 1 and the side in contact with the cement-based foam (in Figure 2The bottom surface of the cutting tool 1 is coated with a polytetrafluoroethylene coating 11. By coating the polytetrafluoroethylene coating, the friction resistance between the cutting edge and the cement-based foam can be greatly reduced at the cutting edge and the contact surface of the cutting tool 1, making the cutting smoother; at the same time, the polytetrafluoroethylene coating has super water-repellent properties, which can effectively prevent the cutting debris from sticking to the cutting edge and the bottom of the tool. It can be understood that since the cutting debris generated by cutting has a high water content and viscosity, if it sticks to the surface of the tool, it will inevitably cause obstacles to the tool's movement and produce "grooves" on the surface of the sample with lower strength, thereby affecting the product quality.
[0037] Please continue reading Figure 2 The cutting angle of the front edge 12 of the cutting tool 1 is preferably 30-35 degrees, that is, the angle between the front edge 12 of the cutting tool 1 and the horizontal plane is preferably 30-35 degrees, which can fully ensure the sharpness of the front edge 12 while taking into account the overall strength and hardness of the tool.
[0038] Please continue reading Figure 3 The cutting tool 1 is provided with two fixing holes 13 at both ends in the X direction, and the connecting line of the two fixing holes 13 is parallel to the product travel direction, that is, the Y direction. The cutting tool 1 is fixed to the second side 220 of the connector 2 through the fixing holes 13 to achieve connection with the bracket 3.
[0039] Please continue reading Figure 1-3 The cutting tool 1 is made of tungsten steel. The advantage of using tungsten steel is that the hardness of tungsten steel is significantly higher than that of traditional carbon steel, stainless steel, manganese steel and other cutting tools, which can ensure the hardness, wear resistance and durability of the tool.
[0040] In a preferred embodiment, the thickness of the cutting tool 1, i.e., the height in the Z direction, is preferably set to 1.0 ± 0.2 mm. It is understood that the thickness setting of the cutting tool 1 should not be too thick or too thin. Too thick will result in too much cutting waste, while too thin will affect the overall strength of the tool. Accordingly, the width of the cutting tool 1, i.e., the Y-direction dimension, is set to 5-50 mm, preferably 10-20 mm. If it is too narrow, it will affect the overall strength and stability of the tool. If it is too wide, the friction will be greater, which will lead to greater resistance to the tool's movement.
[0041] In a preferred embodiment, the coating on the cutting edge and the bottom of the cutting tool 1 adopts a polytetrafluoroethylene coating 11 with a thickness of 1-100 microns, preferably 20-50 microns. The purpose of selecting the polytetrafluoroethylene coating is, on the one hand, to utilize its ultra-low friction coefficient to reduce the friction between the cutting edge, the bottom of the tool and the cement-based foam, thereby reducing the cutting resistance, and on the other hand, to utilize the super water repellency of polytetrafluoroethylene to avoid adhesion with cutting waste with high water content, thereby affecting the cutting rate and the surface quality of the product. If the coating thickness is too large, the coating is easy to peel off from the substrate, and if it is too thin, the coating wears quickly and has poor durability.
[0042] Please continue reading Figure 1 , Figure 4-6 The connector 2 includes a first side 210 and a second side 220 that are fixedly connected. The first side 210 is used to be fixedly connected to the bracket 3, and the second side 220 is used to be fixedly connected to the cutting tool 1. Preferably, the size of the first side 210 is larger than the second side 220, that is, the first side 210 is the long side, or the long side of the connector 2. The second side 220 is the short side, or the short side of the connector 2. The first side 210 and the second side 220 are preferably connected at a right angle, so that the connector 2 is a right-angle connector, and can thus assume the two functions of fixing the cutting tool 1 and adjusting its position up and down on the bracket 3 according to production needs. Please refer to 3-6, the cutting tool 1 is fixed to the second side 220 of the connector 2 by four tool fixing bolts 21 and four fixing holes 13 located at the ends of both sides of the tool; the first side 210 of the connector 2 is fixed to the bracket 3 by a handle bolt 22 and two bracket fixing holes 26 located on the long side (i.e., the first side 210) of the connector 2.
[0043] Specifically, see Figure 4-5 , two tool fixing holes 23 are provided on the second side 220 of the connector 2, and tool fixing nuts 24 matching the tool fixing bolts 21 are welded to the bottom of the tool fixing holes 23. The tool fixing nuts 24 are directly welded to the connector 2, which makes it more convenient to replace the tool.
[0044] In a preferred embodiment, a first spring washer is provided between the tool fixing bolt 21 and the cutting tool 1. The first spring washer is preferably a galvanized carbon steel spring washer 25. The advantage of such a configuration is that by tightening the tool fixing bolt 21, the galvanized carbon steel spring washer 25 can generate a greater pressure, thereby firmly fixing the tool 1 on the second side 220 of the connector 2, and will not slip or loosen due to the external cutting force.
[0045] Please continue reading Figure 4 , Figure 6, two bracket fixing holes 26 are provided on the first side 210 of the connector 2, and a bracket fixing nut 27 matching the handle bolt 22 is welded on the side (i.e., the inner side) of the bracket fixing hole 26 close to the cutting tool 1. The purpose of welding the bracket fixing nut 27 to the connector 2 is to facilitate the upper and lower position adjustment operation of the left straight rod 31 and the right straight rod 32 of the tool 1 and the connector 2. A rubber gasket 28 is provided between the first side 210 of the connector 2 and the bracket 3, and the length and width of the rubber gasket 28 are preferably the same as the length and width of the long side of the connector 2, and two bracket fixing holes of the same size are provided at the position corresponding to the first side 210 of the connector 2. The advantage of such a setting is that by providing the rubber gasket 28 between the rigid connector 2 and the bracket 3, the cutting vibration can be effectively buffered, and the elasticity of the rubber gasket 28 also makes the connector 2 more firmly fixed.
[0046] In a preferred embodiment, a second spring washer is provided between the handle bolt 22 and the bracket 3. The second spring washer is preferably a galvanized carbon steel spring washer 29. By tightening the handle bolt 22, the galvanized carbon steel spring washer 29 can generate a large pressure, thereby firmly fixing the connector 2 on the straight rod of the bracket 3 without slipping or loosening due to the cutting external force.
[0047] See also Figure 1 and Figure 7 The bracket 3 includes a left straight rod 31, a right straight rod 32 and a support beam. One end of the left straight rod 31 and the right straight rod 32 are fixed on the set plane, and the other end is fixedly connected by the support beam. The support beam includes an upper support beam 33 and a lower support beam 34. The upper support beam 33 and the lower support beam 34 are both set at the top of the left straight rod 31 and the right straight rod 32, corresponding to Figure 1 In the middle, the upper supporting beam 33 and the lower supporting beam 34 are both arranged at the top ends of the left straight rod and the right straight rod 32. The advantage of such an arrangement is that the fixed gantry structure can well ensure the stability of the entire support.
[0048] In a preferred embodiment, the left straight rod 31, the right straight rod 32, the upper supporting beam 33 and the lower supporting beam 34 are all square hollow rod structures. The advantage of such a setting is that, on the one hand, it can ensure the overall structural strength and strong supporting capacity, and on the other hand, it can also effectively reduce the weight of the overall cutting equipment.
[0049] In a preferred embodiment, the upper support beam 33 and the lower support beam 34 are both fixed to the top of the left straight rod 31 and the right straight rod 32 by welding, and the distance between the upper support beam 33 and the lower support beam 34 is not less than 1 / 4 of the height of the left straight rod 31 or the right straight rod 32, which can ensure the overall stability of the bracket 3. The left straight rod 31 and the right straight rod 32 are connected to the fixed chassis 4 by welding.
[0050] See also Figure 1 and Figure 7 The side of the left straight rod 31 is provided with a first connector fixing groove capable of adjusting the position of the handle bolt 22 relative to the bracket, and the side of the right straight rod 32 is provided with a second connector fixing groove capable of adjusting the position of the handle bolt 22 relative to the bracket, and the first connector fixing groove 35 corresponds to the position of the second connector fixing groove. Figure 1 and Figure 7 In this preferred embodiment, the left straight rod 31 and the right straight rod 32 have the same structure, and the first connector fixing groove and the second connector fixing groove are the same, both of which are connector fixing grooves 35. More preferably, please refer to Figure 7 The connector fixing groove 35 is located below the lower support beam 34, its width matches the handle bolt 22, and its length in the Z direction is not less than 500mm. When the height of the cutting tool 1 needs to be adjusted, it is only necessary to loosen the bracket fixing nut 27, then move the connector 2 to the specified position, and then tighten the bracket fixing nut. The connector fixing groove 35 can be used to adjust the cutting height of the tool 1 within a certain range, thereby adapting to products with different heights and sizes.
[0051] It can be understood that as long as the first side of the connector can be adjustably fixed to the left straight rod 31 and the right straight rod 32 respectively, the present invention does not impose any limitation on this.
[0052] See also Figure 1 and Figure 8 The fixed chassis 4 includes a left fixed chassis 41 and a right fixed chassis 42, which are used to be connected to the left straight rod 31 and the right straight rod 32 respectively. The left fixed chassis 41 and the right fixed chassis 42 have the same structure, both are square, and the side length is 3-8 times the side length of the cross section of the corresponding left straight rod 31 or right straight rod 32. The center (diagonal intersection) of the fixed chassis is connected to the left straight rod or the right straight rod, and four chassis fixing holes 43 are provided on the diagonal of the fixed chassis 4, which are fixed to the set plane by expansion bolts 44. The connection method of the fixed chassis 4 and the ground can ensure the stability and reliability of the entire cutting equipment.

[0054] It is understood that there are many implementation methods of the conveyor belt in the prior art, such as using a transmission belt and a motor to automatically deliver multiple wall keels to the cement-based foam surface removal device. Of course, it can also be implemented in other ways, such as by crawler transmission.
[0055] In summary, the purpose of this scheme is to propose a cutting device for cutting off the surface layer of ultra-lightweight, fast-curing cement-based foam used for thermal insulation filling of new finished wall products, mainly to solve the following problems: (1) The cutting tool has high hardness and sharpness, which can quickly destroy the hard shell of the cement-based foam surface and is durable; (2) During the cutting process, the cutting tool does not adhere to the internal body structure with low strength and high water content, avoiding obstacles to the tool movement and adhesion of waste chips to produce "furrows" that damage the product surface; (3) The cutting process is efficient and meets the continuous production requirements of the production line.
