Description

Technical Field

[0001] This invention belongs to the field of building materials machinery technology, and relates to a mechanical component for extrusion molding of building materials, specifically a grooving device for extrusion molding of building components. Background Technology

[0002] Building component extruders are equipment used to achieve industrialized production lines for building component materials, primarily in the fields of building component panels and walls. Through automatic water supply, material feeding, and grouting molding processes, this equipment can produce hollow, solid, and composite sandwich building component panels. The building component panels produced by the extruder have smooth, flat surfaces and high density, truly realizing the industrialized production line production of new building component panels.

[0003] Chinese Patent Publication No. CN207606955U discloses a utility model patent entitled "Forming Die for Wall Panel Extruder". The technical description

[0015] describes a die comprising two parallel vertical end plates 1. An upper forming protrusion 4 is integrally fixed to the upper ends of the two vertical end plates 1 facing each other. A lower forming protrusion 5 is integrally fixed to the lower ends of the two vertical end plates 1 facing each other. The lower end face of the lower forming protrusion 5 is flush with the lower end face of the vertical end plate 1. The cross-section of the lower forming protrusion 5 is a right-angled triangle. The upper forming protrusion 4, the vertical end plates 1, and the forming protrusion 3 are integrally formed from stainless steel, which avoids seams at the joints. The gap ensures that the edges of the wall panels are smooth after extrusion molding, facilitating the connection between two wall panels. The cross-section of the lower forming protrusion 5 is set as a right-angled triangle for easy processing. At the same time, it ensures that the edges of the wall panels form a bevel after molding. When the wall panels are connected, even if the flatness is not high, it can be smoothed by the plaster layer, resulting in a smooth wall surface. The opposing surfaces of the two vertical end pressure plates 1 are respectively processed with protrusions or grooves. One vertical end pressure plate 1 has protrusions, and the other vertical end pressure plate 1 has grooves. The protrusions 3 and grooves on the two vertical end pressure plates 1 match each other. Both the protrusions and grooves extend to the two ends of the corresponding vertical end pressure plates 1.

[0004] In practical applications, during the extrusion molding process of the wall panel (building component), the shape of the top surface of the wall panel is formed by the extrusion and drawing of the lower forming protrusion 5, the shape of one side of the wall panel is formed by the extrusion and drawing of the upper forming protrusion 4 and grooves, and the shape of the other side of the wall panel is formed by the extrusion and drawing of the upper forming protrusion 4 and ridge 3. When the bottom surface of the wall panel (building component) needs to be extruded and drawn into various shapes, the technical solution disclosed in the above patent specification cannot be completed.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The present invention provides a groove strip I for a grooved device for extruding and molding building components, which can complete the extrusion and grooving of the bottom surface shape (groove) of the building component during the extrusion and molding process of the building component by the extruder.

[0025] 2. This invention provides a grooving strip I for extruding building components. Located in the middle and rear end of the forming die cavity, the grooving strip is a trapezoidal cone-shaped column with a thicker rear end and a thinner front end. This prevents material shortages such as honeycomb and voids from forming on the bottom groove of the building component during extrusion. Under the extrusion of the trapezoidal cone-shaped grooving strip I, the tensile strength near the bottom groove of the building component is slightly higher than that of other parts of the building component.

[0026] 3. This invention provides a grooving device for extruding building components. The grooving bars II and III are located in the middle and rear ends of the forming die cavity, and are trapezoidal conical columns with a thicker rear end and a thinner front end. This avoids material shortage phenomena such as honeycomb and voids in the double-body grooves and single-body grooves during the extrusion of building components. Under the extrusion of the trapezoidal conical grooving bars II and III, the tensile strength near the double-body grooves and single-body grooves of the building component is slightly higher than that of other parts of the building component.

[0027] The beneficial effects of the present invention are not limited to this description. For better understanding, a more detailed description is provided in the Detailed Embodiments section. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] The grooving device for extruding building components according to the present invention will be further described below with reference to the accompanying drawings and specific embodiments. The grooving device in the present invention has the following two independent embodiments.

[0042] Embodiment 1 of the grooving device of the present invention;

[0043] See Figure 1 and Figure 2 As shown, the grooving device for extruding building components according to the present invention includes a grooving bar I1. The grooving bar I1 is suspended at the bottom of the forming die cavity Aa of the extruder A. Figure 2 The grooved strip I1 shown has its front end fixed to extruder A, while its rear end is suspended above the bottom of the forming cavity Aa of extruder A. (Reference) Figure 1 and Figure 3 As shown, during the working process, the extruder A pulls the grooved strip I1 forward, and the middle and rear ends of the grooved strip I1 are dragged along the working surface B inside the forming cavity Aa of the extruder A.

[0044] refer to Figure 3 As shown, when extruder A moves forward on working surface B, building component D is extruded from forming cavity Aa of extruder A, and grooving strip I1 draws bottom groove Da on the bottom of building component D.

[0045] Embodiment 2 of the grooving device of the present invention;

[0046] See Figure 1 Figure 2 As shown, the grooving device for extruding building components according to the present invention includes a grooving bar I1. The grooving bar I1 is suspended at the bottom of the forming die cavity Aa of the extruder A. Figure 4 As shown, the front end of the grooved strip I1 is fixed to the extruder A, while the rear end is suspended above the bottom of the forming cavity Aa of the extruder A. (Reference) Figure 1 Figure 4 As shown, extruder A is fixedly installed on the upper end of conveyor belt C. The top surface of conveyor belt C is in contact with the bottom surface of the forming cavity Aa of extruder A. When conveyor belt C rotates backward, the middle and rear ends of the groove bar I1 are attached to the conveyor belt C and dragged inside the forming cavity Aa of extruder A.

[0047] refer to Figure 4As shown, the conveyor belt C rotates backward, and the building component D is extruded from the forming cavity Aa of the extruder A and moves backward by the conveyor belt C at the same time. The grooving strip I1 draws the bottom groove Da on the bottom of the building component D.

[0048] To enhance the adhesion stability between the groove strip I of the extrusion molding device for building components described in this invention and the working surface or conveyor belt during extrusion, and to prevent the groove strip I from curling up during extrusion, in the first and second embodiments of this invention, the groove strip I is designed with an arc-shaped elastic shape.

[0049] Specific examples Figure 5 As shown, the grooved strip I1 is located in the forming cavity Aa of extruder A and is elastically arranged in an arc shape, with its arc angle curving towards the lower end of extruder A. (Reference) Figure 1 , Figure 3 and Figure 4 As shown, when extruder A is in working condition, the bottom of the forming cavity Aa of extruder A is flush with the working surface B or the upper surface of the conveyor belt C, and the groove strip I1 is in a straight state with the working surface B or the conveyor belt C under the action of gravity.

[0050] In the first and second embodiments of the grooving device for extrusion molding of building components described in this invention, reference is made to... Figure 1 As shown in Figure 2, it also includes grooved strips II2 and III3. Several grooved strips II2 are fixedly installed on the top wall and side wall of the forming cavity Aa of the extruder A, and several grooved strips III3 are fixedly installed at the intersection of the top wall and side wall, and the side wall and bottom surface of the forming cavity Aa of the extruder A.

[0051] refer to Figure 3 As shown, when extruder A moves forward on working surface B, its forming cavity Aa drives the groove strips II2 and III3 to move forward. Building component D is extruded from the forming cavity Aa of extruder A. The groove strips II2 and III3 draw double-body grooves Db and single-body grooves Dc on the top and side walls of building component D.

[0052] refer to Figure 4 As shown, the conveyor belt C rotates backward, and the building component D is extruded from the forming cavity Aa of the extruder A and moves backward by the conveyor belt C at the same time. The groove strips II2 and III3 draw double-body grooves Db and single-body grooves Dc on the top and side walls of the building component D.

[0053] In the first and second embodiments of the extrusion molding grooving device for building components described in this invention, as follows: Figure 3 Figure 4 As shown, the bottom surface of building component D has an inverted trapezoidal inward-curving structure on both sides of its bottom groove Da, and the bottom surfaces of some of its double-body grooves Db and single-body grooves Dc also have inverted trapezoidal inward-curving structures. (Reference) Figure 1 Figure 2As shown, when the grooving strip I1 of extruder A draws the bottom groove Da of building component D, or when the grooving strips II2 and III3 draw the double-body groove Db and single-body groove Dc of building component D, the building slurry sometimes cannot fill the inverted trapezoidal recessed spaces on both sides of the grooving strip I1 or the inverted trapezoidal recessed spaces of the grooving strips II2 and III3. Due to the above reasons, when building component D is extruded from the forming cavity Aa of extruder A, honeycomb, voids, and other material shortages will appear on the left and right sides of its bottom groove Da or the bottom surface of the double-body groove Db and single-body groove Dc, thus affecting the bonding strength of the bottom groove Da or the double-body groove Db and single-body groove Dc of building component D.

[0054] To solve the above problems, in the grooving device for extrusion molding of building components described in this invention, the grooving strip I, grooving strip II and grooving strip III can be configured with the following structural forms.

[0055] refer to Figure 7 As shown, the groove strip I1 is located in the middle and rear end of the forming mold cavity Aa, and is a trapezoidal cone shape that is thicker at the back and thinner at the front.

[0056] refer to Figure 7 As shown, groove strips II2 and III3 are located in the middle and rear ends of the inner cavity of the molding mold cavity Aa, and are in the shape of a trapezoidal cone with a thicker rear end and a thinner front end.

[0057] refer to Figure 7 As shown, the groove strip I1 is a column of uniform thickness at the rear end of the outlet part of the forming mold cavity Aa, and a trapezoidal conical column with a thicker rear and a thinner front at the middle part of the inner cavity part of the forming mold cavity Aa.

[0058] refer to Figure 7 As shown, groove strips II2 and III3 are columnar with equal thickness at the rear end of the outlet portion of the forming cavity Aa, and are trapezoidal conical columnar with thicker rear and thinner front at the middle portion of the inner cavity portion of the forming cavity Aa.

[0059] like Figure 6 And refer to Figure 3 Figure 4As shown, when extruder A is working, the building slurry fills the forming cavity Aa of extruder A. The front ends of the trapezoidal conical grooved strips I1, II2, and III3 gradually occupy less space in the forming cavity Aa. As extruder A moves, its forming cavity Aa drives the grooved strips I1, II2, and III3 forward. The front ends of the trapezoidal conical grooved strips I1, II2, and III3 gradually increase in space within the forming cavity Aa. The space of the building slurry near the grooved strips I1, II2, and III3 in the forming cavity Aa is gradually squeezed by the grooved strips I1, II2, and III3. After the building slurry is gradually formed in the forming cavity Aa of the extruder A, the equal-coarse columnar groove strips I1, II2 and III3 located at the outlet of the forming cavity Aa gradually pull out the bottom groove Da, double-body groove Db and single-body groove Dc of the complete building component D.

[0060] To enhance the stability of the grooving strip I in the grooving device for extruding building components described in this invention during the grooving process on the bottom surface of the building component, and to further reduce the lateral swaying and vertical vibration of the grooving strip I when dragged on the upper end of the working surface or the upper end of the conveyor belt, the grooving device of this invention also includes a sliding guide mechanism and a guide sliding mechanism.

[0061] Specific Figure 8 Figure 9 Figure 10 As shown, in the first or second embodiment of the extrusion molding device for building components, the sliding guide mechanism 3 is disposed at the upper end of the working surface B or the upper end of the conveyor belt C, and the guide sliding mechanism 4 is disposed at the rear end of the grooving strip I1. When the grooving strip I1 travels along the working surface B or the conveyor belt C, its rear end guide sliding mechanism 4 slides on the sliding guide mechanism 3 on the working surface B or the conveyor belt C. The sliding guide mechanism 3 and the guide sliding mechanism 4 have the following four embodiments.

[0062] Example 1, see Figure 8 As shown, the sliding guide mechanism 3 is a trapezoidal sliding guide rail 3a installed on the working surface B or the conveyor belt C, and the sliding guide mechanism 4 is a cavity structure 1a with an open bottom surface at the rear end of the grooved bar I1. The cavity structure 1a of the grooved bar I1 slides within the trapezoidal sliding guide rail 3a on the working surface B or the conveyor belt C. The trapezoidal sliding guide rail 3a not only restricts the left and right swinging of the grooved bar I1 on the working surface B or the conveyor belt C, but also restricts the up and down vibration of the grooved bar I1 on the working surface B or the conveyor belt C.

[0063] Example 2, see Figure 8As shown, the sliding guide mechanism 3 is a trapezoidal sliding guide block 3b installed on the working surface B or the conveyor belt C, and the guiding mechanism 4 is a cavity structure 1a with an open bottom surface at the rear end of the grooved bar I1. The cavity structure 1a of the grooved bar I1 slides within the trapezoidal sliding guide block 3b on the working surface B or the conveyor belt C. The trapezoidal sliding guide block 3b not only restricts the left and right swinging of the grooved bar I1 on the working surface B or the conveyor belt C, but also restricts the up and down vibration of the grooved bar I1 on the working surface B or the conveyor belt C.

[0064] Example 3, see Figure 9 As shown, the sliding guide mechanism 3 is a double sliding guide groove 3c set on the working surface B or the conveyor belt C, and the sliding guide mechanism 4 is a double sliding guide plate 1b provided at the rear end of the groove bar I1. The double sliding guide plate 1b of the groove bar I1 slides within the double sliding guide groove 3c on the working surface B or the conveyor belt C. The double sliding guide groove 3c not only restricts the left and right swing of the groove bar I1 on the working surface B or the conveyor belt C, but also restricts the up and down vibration of the groove bar I1 on the working surface B or the conveyor belt C.

[0065] Example 4, see Figure 9 As shown, the sliding guide mechanism 3 is a T-shaped sliding guide groove 3d set on the working surface B or the conveyor belt C, and the sliding guide mechanism 4 is a T-shaped sliding conductor 1c provided at the rear end of the pull bar I1. The T-shaped sliding conductor 1c of the pull bar I1 slides within the T-shaped sliding guide groove 3d on the working surface B or the conveyor belt C. The T-shaped sliding guide groove 3d not only restricts the pull bar I1 from swinging left and right on the working surface B or the conveyor belt C, but also restricts the pull bar I1 from vibrating up and down on the working surface B or the conveyor belt C.

[0066] In the above embodiment of the grooving device for extruding building components of the present invention, the double sliding guide groove or T-shaped sliding guide groove can be independently set on the working surface.

[0067] For details, please refer to Figure 9 As shown, the double sliding guide groove 3c or the T-shaped sliding guide groove 3d is independently set on the sliding guide rail 3A, and the groove Ba is provided on the working surface B of the extruder. The sliding guide rail 3A is set in the groove Ba of the working surface B.

[0068] For details, please refer to Figure 10 As shown, the double sliding guide groove 3c or the T-shaped sliding guide groove 3d is independently set on the sliding guide block 3B. The conveyor belt C rotating in the opposite direction below the extruder is set separately, and the sliding guide block 3B is set between the two conveyor belts C.

[0069] The grooving process of the grooving device for extrusion molding of building components according to the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0070] Example 1 of groove forming process;

[0071] refer to Figure 3 As shown, the grooving process includes,

[0072] S1. When extruder A moves forward on working surface B, it drags the groove bar I1 forward.

[0073] S2. As building component D is extruded from the forming cavity Aa of extruder A, grooving strip I1 draws a bottom groove Da on the bottom of building component D, and grooving strips II2 and III3 draw double-body grooves Db and single-body grooves Dc on the top and sides of building component D.

[0074] S3. As the extruder A moves forward, the strip-shaped building components D extruded on the working surface B are sawn into blocks as needed.

[0075] Example 2 of grooving forming process;

[0076] refer to Figure 4 As shown, the grooving process includes,

[0077] S1. As the conveyor belt C rotates backward relative to the extruder A, it drives the grooved strip I1 to move backward.

[0078] S2. As the conveyor belt C rotates backward, the building component D is extruded from the forming cavity Aa of the extruder A. The grooving strip I1 draws the bottom groove Da on the bottom of the building component D, and the grooving strips II2 and III3 draw the double-body groove Db and the single-body groove Dc on the top and sides of the building component D.

[0079] S3. As the conveyor belt C rotates backward, the strip-shaped building components D that are extruded on the conveyor belt C are cut into blocks as needed.
